Large Local Reactions

Extensive swelling and erythema, extending from the sting site over a large area, is fairly common. The swelling usually peaks in 24-48 h and may last 7-10 d a sting on the hand may cause swelling extending as far as the elbow. On occasion, when the reaction is severe, fatigue, nausea, and malaise may be present. If mild, these large local reactions can be treated with aspirin and antihistamines. When a reaction is severe or disabling, steroids such as prednisone, 40 mg daily for 2-3 d, are very helpful in diminishing the swelling. There is no documentation that the application of papain (meat tenderizer) or mud alleviates local swelling. These large local reactions have been confused with infection and cellulitis. Insect sting sites are rarely infected and antibiotic therapy rarely indicated. Tetanus prophylaxis is unnecessary.

The Role of Damage Response Pathways in Stem Cell Aging

Elucidation of the role in stem cells of the ATM (Ataxia Telangiectasia Mutated) damage-response pathway has begun to clear up the picture. To interrelate telomere regulation with cellular damage responses, it should be noted that one of the cardinal roles of ATM is in telomere regulation (80). In Atm ' mice, not only do telomeres dysfunction but cellular oxidant levels rise and it was found that the hematopoietic stem cell population was diminished resulting in aplasia and severe anemia in mice only 6 months old (81, 82). Treatment of Atm ' mice with the hydrogen peroxide scavenger N-acetyl-cysteine rescued the stem cell aplasia and restored self-renewal via mechanisms independent from the role of ATM in maintaining telomere stability (81). In a recently published extension of these studies, Ito and colleagues showed that oxidative stress in stem cells, but not progenitor cells, activated the p38 MAPK pathway, a relatively general damage control pathway responding to diverse cellular...

Molecular Determinants Of Angiogenesis In Cutaneous Hemangiomas

To study the relationship between hemangiomas and the microenvironment, the authors developed an in vivo model to study transitive epidermal hyperplasia and angiogenesis using UV-B irradiation of mice. Mice exposed to 10 kJ m2 UV-B developed increasing epidermal hyperplasia and dermal angiogenesis and telangiectasia during the first week following irradiation, but these slowly subsided over the following 7 wk. The authors investigated the production of positive and negative regulators of angiogenesis in this model, and found that the first striking event following UV-B irradiation was the increase in production of bFGF in the keratinocytes of the epidermis (Bielenberg et al., in press). The increase in bFGF proceeded, or at least coincided with, the division of epidermal cells, recognized by immunohistochemical staining with antibodies to proliferating-cell nuclear antigen (PCNA). Days 3-7 following UV-B irradiation showed marked hyperplasia and angiogenesis. The expression of VEGF...

Introduction and Overview

The title of this book might suggest that one mode of cell death (apoptosis) and one mode of growth arrest (senescence) represent the critical elements of tumor cell responses to various forms of cancer therapy. However, a quick glance through the section and chapter headings will readily convey the range of possible responses to both conventional therapies, such as standard cytotoxic drugs and radiation, to more recent therapies, such as monoclonal antibodies and targeting of specific receptor and signaling pathways, to developing modalities, such as photodynamic therapy and approaches targeting the vascular system. With regard to senescence, in addition to the relatively recent realization that senescence is likely to mediate the growth arrest response to many therapeutic treatments and could potentially act as a rational drug response, a considerable section of this book has been devoted to the role of senescence in genomic instability and tumor development. In addition, the reader...

Angiogenesis Associated with Other Pathological Conditions

It has been shown that VEGF expression is increased in psoriatic skin (181). Increased vascularity and permeability are characteristic of psoriasis. Also, VEGF mRNA expression has been examined in three bullous disorders with subepidermal blister formation, bullous pemphigoid, erythema multiforme, and dermatitis herpetiformis (182).

Clinical features

Patients are adults of both sexes 1,2,44 . Reports in children exist but phenotypical data in some cases are incomplete 45,46 . A long history of 'benign panniculitis' is often present 22 . Clinically, patients present with solitary or multiple erythematous tumours or plaques, which are usually not ulcerated and are located most commonly on the extremities, especially the lower ones (Figs 5.1 & 5.2) 1,2,44 . Other sites of the body, including the head, may be affected (Fig. 5.3) 22,47 . Skin lesions are non-specific and may simulate erythema nodosum, lupus panniculitis or other panniculitic diseases. One patient with alopecic lesions on the scalp has also been described 48 . Spontaneous resolution of some of the Fig. 5.1 Subcutaneous T-cell lymphoma. Erythematous plaques ('panniculitis-like') on the leg. Fig. 5.1 Subcutaneous T-cell lymphoma. Erythematous plaques ('panniculitis-like') on the leg. Fig. 5.2 Subcutaneous T-cell lymphoma.

Blepharitis is inflammation of the eyelid margins that is most often misdiagnosed as an ocular allergy because it commonly causes conjunctivitis as well. Infection or seborrhea are common causes. As in patients with atopic dermatitis, the most important organism isolated from the lid margin is Staphylococcus aureus. Antigenic products and not the colonization itself are thought to play the primary role in the induction of chronic eczema of the eyelid margins. The symptoms include persistent burning, itching, tearing, and a feeling of dryness. Patients commonly complain of more symptoms in the morning than in the evening. This is in contradistinction to patients with dry eye syndromes, who complain of more symptoms in the evening than in the morning because of drying out of the tear film during the day. The crusted exudate that develops in these patients may cause the eye to be glued shut when the patient awakens in the morning. The signs of staphylococcal blepharitis include dilated...

Radiofrequency Surgery as a Refinement in Aesthetic Surgery

Other operations such as rhinophyma treatment, endoscopic browlift, hair transplant, and tumour removal will benefit from 4.0 MHz radiosurgery, as would many major surgical interventions such as breast surgery, dermolipectomy, abdominal plastic surgery, and vein surgery. A particular issue is the minimal scar tissue formation. At times we are even able to make some scars invisible.

Postnatal Rubella Symptoms And Signs

Transmission occurs by droplet inhalation. The incubation period is 2-3 weeks, but may be prolonged after administration of specific immunoglobulin. Many cases run asymptomatically or atypically (without rash). Mild conjunctivitis and fever are sometimes observed as prodromes, especially among adults. The rash, which is pinpoint maculopapular, spreads from face to neck and over the trunk as pink, slightly raised macules, which may coalesce. There may be petechiae on the soft palate, conjunctivitis and mild catarrhal symptoms. Posterior cervical, postauricular and occipital lymph nodes are often enlarged and tender. The swelling may persist for 2-3 weeks. Fever is low grade or absent during the rash. Some patients have a more generalized lymphadenopathy and splenomegaly with slight fever during the rash, but the general condition is good. The white cell count is lowered with increased plasma cells and a relative increase in both small and large atypical lymphocytes (Turk cells)....

Cell Cycle Regulation And Checkpoint Arrest

The G2 S checkpoint is monitored by the serine threonine checkpoint kinase 1 (CHK1). Upon DNA damage the protein kinase ATR (ataxia-telangiectasia mutated - rad53 related kinase) is activated (6,7). ATR-dependent phosphorylation of CHK1 promotes its phosphorylation of cdc25 and Wee1 and ultimately inactivation of cdc2.

Skin Anomalies Pathological Noninfective

Lichen planus is an inflammatory eruption of the skin and mucous membranes of unknown aetiology. In the reticular (lacy) pattern there may be mild to severe pruritus, and the erosive and ulcerative form presents with pain and burning. On examination there may be small purple papules with a lacy or reticulated surface. In erosive disease there may be a glazed erythema with tenderness to touch or frank almost ulcerated erosions, often with a lacy or slightly greyish edge. Eczema is a non-infectious condition that may develop following skin irritation or via an immune pathway. Eczema is a collection of clinical findings rather than a particular disease. Patients may present with papules, vesicles, erythema, fissures, weeping and oedema in an acute stage. Itching is often present, and angular and linear erosions produced by finger nails are common. Scaling and lichenification are common in the chronic stage. When lichenification occurs on the mucous membrane of the vulva the skin...

Osler WeberRendu Syndrome

Osler-Weber-Rendu syndrome is also known as hereditary hemorrhagic telangiectasia. It is inherited in an autosomal dominant manner and is characterized by telangiectasias of the skin and mucous membranes and recurrent GI bleeding. Telangiectasias are most common in the stomach and small bowel, although they can be encountered in the colon as well. Bleeding is usually encountered as melena. Although the optimal treatment method has not been determined, lesions can be treated with endoscopic ablation. If endoscopic treatment fails, then surgical resection can be performed. Combination estrogen progesterone hormonal therapy can reduce the transfusion requirements. Hormonal therapy is best used in patients with diffuse lesions or lesions that are inaccessible to endoscopic or surgical treatment (9).

Other Infective Conditions Commonly Seen In Gum Clinics

Adult lice and their eggs can be seen with the naked eye and may appear initially as scabs. Closer visualisation using magnification reveals their true identity. The insects feed on host blood, which they obtain by biting. Patients may present with itching or redness, which is a result of the bites. This reaction varies from person to person. Generally in unexposed people a period of five days can pass before allergic sensitisation occurs, leading to itching, which in turn leads to scratching, erythema, and inflammation. It may be possible also to observe dark-coloured specks on the skin or underwear. There are louse excreta.

Vascular Malformations

Clear that vascular malformations can cause bleeding in any location left colon, stomach, or small bowel. Multiple lesions are present in 3075 of patients. Vascular malformations are probably best considered as a degenerative disease of aging, because they are most common in patients older than 60 years. The exact prevalence in the general population is unknown because many patients are asymptomatic, with lesions discovered only incidentally during bowel resection for another indication or during autopsy. Based on these data, their prevalence in the general population is estimated to be approximately 3 (16). Aortic stenosis and chronic renal failure have been reported to be associated with vascular malformations, although a recent review of the literature shows no clear association between aortic stenosis and vascular malformations (17). A recent study indicated that most patients with bleeding angiodysplasia or telangiectasia have a deficiency of the largest

History And Physical Examination

History and physical examination may sometimes provide clues to the cause of obscure GI bleeding. A directed history can reveal the use of medications known to cause mucosal damage or exacerbate bleeding nonsteroidal antiinflammatory drugs (NSAIDs), alendronate, potassium chloride, and anticoagulants . A family history of GI blood loss will expand the differential diagnosis to include hereditary hemorrhagic telangiectasia, blue rubber bleb nevus syndrome, and intestinal poly-posis. Typical lesions can be found on the upper extremities, lips, and oral mucosa in patients with hereditary hemorrhagic telangiectasia. Patients with blue rubber bleb nevus syndrome can have cutaneous hemangiomas in addition to those in the GI tract. Some rare causes with typical findings on physical examination include celiac sprue (dermatitis herpetiformis), AIDS (Kaposi's sarcoma), Plummer-Vinson syndrome (brittle, spoon-shaped nails, atrophic tongue), pseudoxanthoma elasticum (chicken-skin appearance,...

Clinical Manifestations

With infection in the anterior compartment, there is usually high fever and chills, tender swelling below the angle of the mandible, induration and erythema of the side of the neck, and trismus. Most patients are acutely ill, have odynophagia, dysphagia, and mild dyspnea. A bulge in the lateral pharyngeal wall can be observed but the tonsil is normal in size and relatively uninflamed. Torticollis toward the side of the abscess (due to muscle spasm) is found often as is cervical lymphadenitis (CL). The classical triad of pharyngomaxillary abscess occurs only in anterior compartment syndrome and includes (i) tonsillar and tonsillar fossa prolapse, (ii) trismus, and (iii) swelling of the parotid area. Infection in the posterior compartment is characterized by signs of septicemia, with minimal pain or trismus. Swelling can often be overlooked because it is deep behind the palatopharyngeal arch. Indirect laryngoscopy can reveal ipsilateral obliteration of the pyriform sinus. A tender high...

Laboratory Diagnosis

Diseases mimicking oral herpes infections are other vesicular or ulcerating lesions herpangina caused by coxsackie virus, mononucleosis by Epstein-Barr virus, Stevens-Johnson syndrome, aphthous stomatitis, bacterial infections or lesions caused by drug intolerance, irradiation or immunosuppressive therapy. The diagnosis of genital HSV infection should include chancroid, syphilis, genital lesions, Behcet syndrome, erythema multiforme, local candidiasis and simple erosions. The symptoms of neonatal herpes can be caused by other infections such as rubella, cytomegalovirus and toxoplasma, and sometimes by erythroblastosis.

Other Disorders That May Affect The Basal Ganglion Disorders And May Have Abnormal Eye Movements

Ataxia telangiectasia results from a defect on chromosome 11q. Characteristic eye signs include an ocular motor apraxia with hypometria and increased latency, but normal velocity of saccades with head thrusts (116-119). Both vertical and horizontal saccades are affected. Other features are gaze-evoked nystagmus, periodic alternating nystagmus, square-wave jerks, and unusual slow smooth-pursuit-like movements that are used to change gaze voluntarily when saccades are difficult to generate. a-Feto protein levels are usually dramatically elevated.

Diagnosis of catheterrelated infection

Although a catheter maybe suspected of being infected, in fact this is the case in only about 25 of instances, meaning that many catheters are removed unnecessarily. The predictive value of several markers of infection were studied by Armstrong in 1990.8 Clinical symptoms such as erythema and pyrexia, and skin site and blood cultures were investigated. It was shown that skin site cultures showing more than 50cfu were high predictors of infection, and erythema and temperature had relatively low predictive values.

Prevention of catheterrelated infection

Scheduled changes of central venous catheters at fixed intervals are of no benefit, and may actually increase the infection risk, compared to as-needed replacement.19 Replacement of central venous catheters can be achieved using placement of a new catheter at a new site or by using the Seldinger technique to change the catheter over a guidewire. This can be useful when a potentially infected catheter needs to be replaced in a febrile patient with no signs of infection at the catheter insertion site and no other obvious source of infection, and to avoid venepuncture in patients with poor venous access due to burns, obesity, or a coagulopathy. Studies have suggested that exchanging catheters over a guidewire may be associated with fewer mechanical complications, and no significantly increased risk of infection compared with placement of a new catheter at a different site, although this may to some extent reflect staff inexperience. A comprehensive review of the guidewire exchange...

Diagnosis and Treatment

Subsequent to barium enema, colonoscopy has become the procedure of choice for diagnosing colonic ischemia. The advantages of colonoscopy over barium enema include greater sensitivity, direct visualization of the mucosa, and the ability to obtain tissue samples by pinch biopsy. Colonoscopy also is preferred over the simpler sigmoidoscopy since approximately 50 of ischemic lesions in the colon are proximal to the sigmoid colon (24). Findings at endoscopy include hemorrhagic nodules, ulcers, mucosal erythema, edema, and friability. These findings are typically segmental, with the intervening mucosa being normal. If the colonoscopist finds mucosal changes suggesting necrosis (cyan-otic gray or black mucosa), the procedure should be terminated owing to an increased risk of perforation (33). Furthermore, colonoscopy in any setting of suspected ischemia should be performed with caution, utilizing minimal air insufflation, since overdistention of the colon could lead to diminished colonic...

Sulfonamides and Other Antibiotics

Extended oral TMP-SMX desensitization procedures have proved successful in a limited series of patients 10-23 d (19 21 patients) 10 d (23 28 patients) 2 d (6 7 patients). Use of full-dose challenge or desensitization is not advised for any patient who has a prior history of drug-associated erythema multiform, SJS, or TEN. The management of these situations is best left to the allergist immunologist or an infectious disease specialist. Recent evidence would indicate that individuals who develop a rash to sulfonamide antibiotics are not at risk for a reaction to sulfonamide containing nonantibiotic drugs because of cross-reactivity, but may be a risk because of having multiple drugs sensitivity (see Suggested Reading, Storm et al.).

Secondgeneration Antihistamines

Another difference between first- and second-generation antihistamines is that some of the latter bind to the H2, as well as the H1, receptor. This appears to be especially important for azelastine and epinastine. This property could at least be theoretically important in that the capacitance vessels in the nasal turbinates and the conjunctiva respond to the H2 stimulation by dilating, thus causing nasal congestion and conjunctival erythema. This may explain the observation that azelastine reduces nasal airway resistance, an effect not associated with the administration of an H1 antagonist.

Necrotizing Fasciitis

Streptococcal gangrene is an infection due to either group A, C, or G streptococci, initiated as an area of painful erythema and edema, which is followed in 24 to 72 hours by dusky skin, and yellowish to red-black fluid-filled bullae (3). The area is demarcated and is covered by necrotic eschar, surrounded by erythema resembling a third-degree burn. Unless treated a rapid progression occurs with frank cutaneous gangrene, accompanied sometimes by myonecrosis. Penetration along fascial planes can occur, followed by thrombophlebitis in the lower extremities, bacteremia at metastatic abscesses, and rapid death. Differentiation between cellulitis and NF is important. Cellulitis can be treated with antimicrobials alone while NF requires also surgical debridement of necrotic tissues. NF due to mixed anaerobic-aerobic flora is usually associated with endogenous source of the organisms, and presents in slightly different fashion. The involved area is first erythematous, erythematous ing...

Gangrenous Cellulitis in the Immunocompromised Host

Cellulitis in the immunocompromised can be caused by expected pathogens as well as opportunistic ones. Pseudomonas aeruginosa is the major pathogen causing a sharply demarcated necrotic area with black eschar and surrounding erythema that may evolve from initial hemorrhagic bulla. Rhizopus spp. can be indolent, with slowly enlarging black ulcer, or may be rapidly progressive. The lesion has a central anesthetic black necrotic area with surrounding violaceous cellulitis and edema (10). Ulcerative or nodular lesions due to opportunistic organisms can develop in immunocompromised patients after trauma.

Cardinal Signs and Symptoms

The diagnosis is best made by flexible sigmoidoscopy. Lesions typically begin near the dentate line and extend for a few centimeters proxi-mally. The characteristic findings are pallor or patchy erythema of the mucosa with prominent telangiectasias, friability (easy bleeding with contact), and occasional ulcerations.

DNA Damage Response During CSR

DNA DSBs represent a severe threat for genome integrity and therefore highly sensitive DNA damage signaling and amplification mechanisms have evolved (Sancar et al., 2004). In response to DSB formation, a complex network of proteins is activated in order to impose cell cycle checkpoints, regulate cell survival, and induce DNA repair (Sancar et al., 2004). These responses are tightly coordinated by a family of serine threonine kinases, containing a phospatidylinositol-3-kinase domain that includes ataxia-telangiectasia mutated (ATM), DNA-PKCS, and ATM- and Rad3-related (ATR) (Shiloh, 2003). These kinases are the prototype transducers of the DNA damage signal (Shiloh, 2003). Among these, the ATM kinase plays a prominent role in the response to DSB and disruption of ATM in mice or in humans results in ataxia-telangiectasia (A-T), a syndrome characterized by radiosensitivity, chromosomal instability, cancer predisposition, and immunodeficiency (Barlow et al., 1996 Borghesani et al., 2000...

Other Side Effects of ATRA

Other side effects, including bone marrow necrosis 11 , hypercalcemia 122 , erythema nodosum 123 , marked basophilia 124,125 , severe myositis 126 , Sweet syndrome 127,128 , Fournier's gangrene (necrotizing fasciitis of the penis and scrotum) 129, 130 , thrombocytosis 131 , and necrotizing vasculitis 132 have rarely been reported with ATRA treatment.

Other Obscure Etiologies

Dieulafoy's lesions are minute mucosal defects that may be barely visible on endoscopy but can bleed significantly because they are located directly over a submucosal artery. These lesions were long ago recognized as a cause of upper GI bleeding but more recently were reported as a cause of obscure lower GI bleeding from the intestine or colon (42). Elastic tissue disorders such as pseudoxanthoma elasticum and Ehlers-Danlos syndrome are rare hereditary diseases that can be complicated by lower GI bleeding (43,44). Other disorders that can be recognized by their manifestations in the skin include the Osler-Weber-Rendu syndrome of hereditary hemorrhagic telangiectasia and the blue rubber bleb nevus syndrome (45). The lesions are visible endoscopically. Bleeding

Slapped cheek disease A popular name for the infectious childhood rash called Erythema infectiosum, the major manifestation of infection with B19 virus. An exanthematous rash illness that gives the child the appearance of having slapped cheeks. In 1905 Cheinisse gave it the name 'fifth disease' of six erythematous rash diseases of childhood which he described. Other names given to it include 'academy rash' and 'Sticker's disease'.

Clinical Signs and Diagnosis

The wound can look benign, with minimal erythema, induration or discharge, but the organism and toxin are usually present. Wound botulism has been reported in parenteral drug abusers (31,32). Therefore, botulism should be considered in any patient with typical neurologic symptoms, even if gastrointestinal symptoms are not present.

Minimizing Side Effects

Side effects of topical retinoid use include initial local irritation, including erythema, burning, stinging, peeling, and xerosis (1). These symptoms usually peak after two weeks of use, and subsequently diminish and then resolve once the skin adapts to the use of the product (1,3,18). Factors influencing the extent and duration of irritation include concentration of the medication used, vehicle of delivery, frequency and amount of application, skin type, and environmental factors such as use of abrasive cleansers or other topical alcoholic agents, ambient xerosis, and exposure to the sun (1'6'14'18'28). Higher concentratations or use of a gel or solution vehicle predisposes to the most irritation. Topical retinoids produce more irritation when used by patients with eczema, rosacea, or other conditions of skin sensitivity, including exposure to extreme weather (2,14). In these patients and during the winter, lower concentrations and the milder forms and vehicles should be utilized...

Characteristics of staff authorised to take responsibility for the supply or administration of medicines under Patient

Clinical condition - The PGD is applicable to any patient (male or female) who has been diagnosed with genital candidiasis. Genital candidiasis is a fungal infection and is commonly caused by the species Candida albicans. In women the sites of infection may include the vulva, vagina and the urethra, and in men the most common sites include the glans, prepuce and urethra. Signs and symptoms are variable. Women may complain of a thick white vaginal discharge, pruritus, soreness, erythema, dysuria and dyspareunia. Fissuring may be apparent on the vulva. Men may present with a visible rash on the glans and they may also complain of pruritus and dysuria. Diagnosis is confirmed either clinically, microscopically (by wet and dry slide) or by culture media. Inclusion criteria - symptomatic patients who have had Candida diagnosed clinically and or microscopically, and symptomatic patients who have had Candida diagnosed on culture. Exclusion criteria - this includes female patients who have...

Historical Perspective

A new drug application (NDA 12-611) was originally submitted for thalidomide in September 1960 to the then Bureau of Medicine (a precursor to the FDA) (8). It was being indicated for use in the treatment of somnolence and as a mild hypnotic. At that time thalidomide was widely used in Europe and was considered a safe and effective sedative. The application was found to have significant shortcomings by three reviewers and additional data was requested. In February 1961 reports emerged of peripheral neuritis occuring in individuals receiving long-term treatment with thalidomide, a further delay in the application, which caused review. In addition, concerns were starting to be raised about possible adverse effects to the fetus if administered during pregnancy. In November 1961 the application was put on hold and subsequently withdrawn because of data from Germany suggesting an association between phocomelia (a rare birth defect) and thalidomide. In 1965 efficacy was reported in the...

How Does One Manage A Patient With Suspected Contact Dermatitis

Treat with a steroid in petrolatum (only) and test this to be sure it is tolerated. Hydrocortisone has to be tested as an intradermal (Solu-Cortef 1 mg 0.05-0.1 mL) and read at 72 h. Any erythema at that time is suspect most can be confirmed with a usage test to one area.

Pathological Infective Skin Rashes That May Be Seen In Gum Clinics

Candida infections can cause marked skin irritation and oedema. Erythema is commonly present in women and fissuring may occur at the introitus. Though infection is less common in men, mild erythema and balanitis or balanoposthitis may occur, with fissuring of the prepuce.

Gloves and socks syndrome A petechial or papular-purpuric rash on the hands and feet of children and adults. Following infection there is acute onset of fever, exanthem, edema and erythema of the hands and feet that has been associated with parvovirus B19 infection syndrome has also been described in relation to cytomegalovirus infection.

Clinical Aspects of Inflammatory Bowel Disease in Humans

In addition to these pathological features within the gastrointestinal tract, Crohn's disease and ulcerative colitis are commonly associated with systemic, extra-intestinal features. Inflammation in the eye, both uveitis and episcleritis, are not uncommon in Crohn's disease patients. Arthritis is another complication and can result in chronic pain in large and small joints as well as the spine. There are also examples of blood diseases, such as hypercoagulability, and skin diseases, such as erythema nodosum due to inflammation in the subcutaneous tissue, in Crohn's disease patients. The biliary tract can also be involved in the form of primary scle-rosing cholangitis.

Symptoms And Signs

Transmission is commonly by droplet inhalation. Rarely, the transfusion of blood or blood products may lead to infection. At the peak of the viraemia, 1 week after exposure, there may be a mild flu-like illness with fever, chills and malaise, lasting 2-3 days. In many cases infection occurs without further symptoms. In erythema infectiosum the first sign is often marked erythema of the cheeks (slapped cheek appearance). A faint pink macular or maculopapular rash then develops on the trunk and limbs. As the rash fades a lacy or reticulate pattern may emerge. Recrudescence is common, especially after bathing or exposure to sunlight. In adult women symmetrical arthropathy is common (80 of cases), involving ankles, knees, wrists and fingers. This is normally resolved within 2-4 weeks. Low-grade fever may be present, and the rash may be pruritic. Leukopenia, reticulocytopenia and thrombocytopenia occur. Differential diagnosis. Other exanthems, especially rubella, also scarlet fever,...

Clinical Presentation

Ulcerative colitis typically begins in the rectum and extends proxi-mally. Symptoms tend to develop gradually, with the predominant symptom of diarrhea, accompanied by blood. Occasionally it may begin with infrequent stools but pure rectal bleeding, secondary to the significant rectal inflammation, resulting in a functional right-sided constipation. The course is usually chronic, characterized by remission with intermittent episodes of relapse (7). Less commonly, the course may be continuous, with unrelenting symptoms and eventual surgery. The severity of the symptoms tends to parallel the severity of the inflammation, not necessarily the extent. In other words, a limited extent does not guarantee a more benign course. Symptoms range from occasional rectal bleeding even without diarrhea to profuse purulent bloody diarrhea. Patients may experience lower abdominal pain, urgency, tenesmus, and incontinence. With more severe inflammation, patients also have systemic complaints such as...

Clinical Manifestation

Be manifested by abdominal distention tenderness, delayed gastric emptying and vomiting. General symptoms can progress insidiously and include increased apnea and bradycardia, lethargy, and temperature instability. Fulminant NEC presents with acidosis, disseminated intravascular coagulation, peritonitis, profound apnea, rapid cardiovascular and hemodynamic collapse, and shock. Stools-reducing substance are elevated, the stools will show traces of occult blood, and diarrhea may be present. As abdominal distention progresses, the gastric residuals rise, and within a short period the urine volume decreases and osmolarity rises. Abdominal erythema can appear and gastric aspirate becomes bile stained. At this stage, the child may have hypotension and may have gross blood in diarrheal stools.

Tcell And Combined Disorders

An immunodeficiency also associated with physiological abnormalities, ataxia-telangiectasia (AT), is characterized by both humoral and cellular deficiency in conjunction with cerebellar ataxia, ocular and skin telangiectasia, and a marked predisposition to the development of lymphoid malignancies. AT is autosomal recessive in inheritance, wherein the genetic defect is located on chromosome 11 and codes for the ATM (AT, mutated) protein. The ATM protein has been implicated in the control of cell cycle checkpoints, DNA repair, and maintaining telomere length. The thymus is often A variant of AT, Nijmegen breakage syndrome (NBS), is also characterized by T- and B-cell defects as well as radiosensitivity and a predisposition to cancer. NBS is unique in presenting with moderate mental retardation, facial dysmorphism, and an increased frequency of microcephaly while lacking telangiectasia and progressive ataxia. The defect results from mutations in the gene that codes for nibrin, a protein...

Phototherapy and Laser Therapy of Acne

Anderson et al. (6) have reported a series of 22 patients with acne of the back, who were sensitized aggressively with ALA and then irradiated with a potent dose of broadband (550-700 nm) light. Pain, erythema, and evidence of epidermal damage were common. Patients experienced a flare of acne that was suppressed by following treatments. Although the adverse effects were significant, there was histologic evidence of damage to sebaceous glands and patients had suppressed sebum production for at least 20 weeks after treatment. Although the adverse effects of this regimen are probably too severe for a practicable therapy, the report serves as a wonderful proof-of-principle study, documenting that the sebaceous gland can be destroyed by a limited number of light treatments. Similarly, Lloyd and Mirkov (7) demonstrated that indocyanine green accumulates in the sebaceous gland and can be activated by 810-nm light to damage the sebaceous gland, yet relatively spare the epidermis. All that...

Background 21 Cosmetic Procedures

Laser and light-assisted hair removal is based on the principle of selective photothermolysis. Selective absorption by hair chromophores of energy from lasers and broadband light sources may result in destruction of hair follicles while leaving the skin undamaged, although there are significant differences according to the specific characteristics of the patients and techniques used (8). In general, laser therapy is more effective in women with darker hair and lighter skin. Efficacy is lower and complications are more common in women with darker skin. Transient erythema and edema are common after laser therapy, and blistering, crusting, or alterations in skin pigmentation may also occur.

Erysipelas and Cellulitis

As previously mentioned, diagnosis of erysipelas and cellulitis can generally be made on a clinical basis. The value of needle aspiration for the bacteriologic diagnosis of these infections has not been clearly demonstrated, particularly in adults. Of note, a higher percentage of positive cultures of soft tissue aspirates along the advancing margin of erythema using a 22- or 23-gauge needle attached to a 3- or 5-mL syringe may be achieved in children with cellulitis.5 If received by the laboratory, aspirates should be inoculated onto blood and chocolate agars, as well as a broth such as trypticase soy broth.

Metabolism And Inactivation

(1) Local allergic reactions, which are of three types. The commonest is the late-phase reaction, a biphasic IgE reaction characterized by immediate burning and pruritus with a wheal and flare at the injection site. It may resolve or become indurated, with pruritus continuing for hours to days. Two rarer forms are the Arthustype reaction, producing a pruritic painful nodule 6-8 h after injection, and the delayed hypersensitivity reaction, which is similar but appears 12-24 h after injection. The local reactions are characterized by swelling, erythema, pruritus and lipoatrophy at injection sites they usually disappear with continued treatment. Generalized allergy may produce urticaria, angioedema and, very rarely, anaphylactoid reactions if continued therapy with insulin is essential, desensitization procedures may need to be performed (Wintermantel et al., 1988). Erythema, swelling or pruritus may occur at injection sites. Such localized allergic manifestations usually resolve within...


Reactions to insulin include local or systemic reactions and insulin resistance. Although human recombinant DNA insulin appears to be less antigenic than bovine-type insulin, it can cause allergic reactions. Local reactions are the most common and are generally encountered during the first 1-4 wk of therapy. They are usually IgE-mediated and consist of mild erythema, swelling, burning, and pruritus at the injection site. These local reactions usually disappear in 3-4 wk with continued administration of insulin. Dividing the insulin dose into two or more sites or switching to a different preparation is generally helpful. If not, antihistamines may be given until the reaction disappears. Local reactions may precede anaphylactic reactions. Therefore, epinephrine should be available to these patients. Systemic reactions include urticaria, angioedema, bronchospasm, and hypotension. Most of these reactions occur upon re-starting of insulin after an interruption in therapy. In treatment of...

DNA Damage Repair

The DNA damage response or DSB repair (double-strand break repair) pathway (or during the S-phase checkpoint, the DNA replication stress response pathway) occurs in response to DSB DNA damage. The DSB repair pathway includes a cascade of events sensing of the DNA damage and transduction of the damage signal to multiple pathways (cell-cycle checkpoints, DNA repair, responses to telomere maintenance, and apoptosis) (see Chap. 4). The DSB repair process involves many genes and their products, including the MRE11-Rad50-NBS 1 complex (MRN) X-ray repair cross-complementing (XRCC) the PI3K-like protein kinases (PIKKs) DNA-PKcs, ATM (mutated in ataxia telangiectasia), and ATR (ATM-Rad3related) and ATM substrates NBS1 (Nijmegen breakage syndrome protein 1), SMC1 (structural maintenance of chromosomes 1), Chk1, Chk2, MRE11, p53, MDM2, BRCA1 (breast cancer protein 1), BRCA2 FANCD1 (breast cancer protein 2 Fanconi anemia protein D1), and FANCD2 (Fanconi anemia protein D2).250-269

Clinical Examination

The clinical examination of the eyes for signs of ocular allergy begins with the external components that surround the eye and the eye itself. First, one examines the eyelids and eyelashes, focusing on the presence of erythema on the lid margin, as well as telangiectasias, scaling, thickening, swelling (blepharitis, dermatitis), and collarettes of debris at the base of the eyelashes, and evidence of periorbital discoloration, blepharospasm, or ptosis. Next, the conjunctivae are directly examined for chemosis (clear swelling), hyperemia (injection), palpebral and bulbar papillae, and cicatrization (scarring). The discharge from the eye is also noted for increase or discoloration. It is important to differentiate this from the injection associated with inflammation of the sclera (scleritis) that tends to develop over the course of several days. Scleritis is also commonly associated with autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis, and Wegener's...

Ocular Examination

The ocular examination begins with the eyelids and lashes. One should look for evidence of lid margin erythema, telangiectasia, thickening, scaling, and or lash collars. The sclera and conjunctiva are then examined for the presence of redness (injection). Certain characteristics that can assist in pinpointing the diagnosis are characterized here.

Clinical Signs

Fever occurs in many of the cases of nasopharyngitis. With adenoviral and influenza viral disease, the pharyngeal findings are prominent, but with other respiratory viruses, rhinitis is more notable. In adenoviral infections, follicular pharyngitis and exudate are common. In contrast, the other respiratory viruses usually induce only pharyngeal erythema. Nasophar-yngitis of a viral etiology is most often an acute, self-limited disease lasting from 4 to 10 days. Adenoviral illnesses tend to be more prolonged than other respiratory viruses. Other symptomatology in nasopharyngitis is related to the causative virus.

Other Disorders

Leiner's disease (erythroderma desquamativum) is a disorder that usually begins during the first few months of life and is characterized by severe generalized seborrheic dermatitis, intractable diarrhea, recurrent infections (usually Gram-negative organisms), and marked wasting and dystrophy. The dermatitis involves an intense erythema of the entire body and extensive large, yellow, greasy scales affecting large portions of the body surface. These scales are desquamative, and large skin areas may slough. IgE levels are typically normal and eosinophils are not present. The exact etiology of this disease is unknown but a familial form exists and has been associated with dysfunction of the fifth component of complement (C5). Langerhans' cell histiocytosis disease is a lethal disorder that is a spectrum of diseases affecting the reticuloendothelial system. A subset of that spectrum, previously known as Letterer-Siwe disease, involves a dermatitis that displays features of both seborrhea...

Endoscopic Therapy

Angiodysplasias, gastric antral vascular ectasia, vascular malformations in blue rubber bleb nevus syndrome, and hereditary hemorrhagic telangiectasia have been treated successfully using thermal contact probes, injection sclerotherapy, argon plasma coagulation, and neody-mium yttrium-aluminum-garnet (Nd YAG) laser. However, most angiodysplasias are not bleeding at the time of the diagnosis, and up to 50 of patients with angiodysplasia found upon investigation of GI bleeding do not have bleeding again over several years of follow-up. Nonbleeding angiodysplasia is also found with other potential sources of bleeding. Endoscopic cauterization of bleeding angiodysplasia found on enteroscopy has been shown to decrease the requirement of blood transfusions significantly compared with no treatment (46). In a trial using the Nd YAG laser, sustained reduction of transfusion requirements was found in 100 of patients with angiodysplasia, 75 with gastric vascular ectasia, and 66 with hereditary...


Scopic therapy or surgical resection or when bleeding is recurrent, the diagnosis is unknown, and vascular lesions are suspected (49). In uncontrolled open-label studies, patients with chronic renal failure and GI bleeding caused by angiodysplasia are reported to benefit from estrogen-progesterone combination therapy. In a double-blind randomized, crossover trial, six of eight patients with hereditary hemorrhagic telangiectasia and von Willebrand's disease stopped bleeding during the hormonal therapy arm. However, in a cohort study of patients with small bowel angiodysplasia, treatment with combination hormonal therapy did not alter transfusion requirements or rebleeding rates compared with untreated controls. Other pharmacotherapeutic agents that have been used with partial success in epistaxis and GI bleeding from hereditary hemorrhagic telangiectasia include danazol (antigonadotrophin with weak androgenic activity) and desmopressin. Anecdotal reports suggest improvement in...

Food Anaphylaxis

The signs and symptoms of anaphylaxis resulting from food allergy are no different from those of anaphylaxis as the result of allergy to P-lactam antibiotics, stinging insects, or natural rubber latex. The symptoms and signs may be mild or severe. Milder symptoms signs include contact urticaria, generalized pruritus, erythema, and urticaria with or without angioedema. More severe symptom signs occur with generalized systemic anaphylaxis from a food and may be multiple or single in nature. These symptoms include laryngeal edema, rhinitis with or without conjunctivitis, asthma, blood pressure decrease, or shock and possible cardiovascular collapse and death. Occasionally, additional symptoms include nausea, vomiting, abdominal cramps, diarrhea, and uterine or bladder cramps.


A flexible sigmoidoscopy without preparation should be performed in patients with signs and symptoms of proctitis or colitis (Fig. 1). If performed gently, the information obtained will outweigh the risk of potentiating bleeding or perforation. Endoscopy allows for characterization of the mucosa, acquisition of biopsies, and aspiration of more stool. Examination of the mucosa may distinguish among infectious colitis, ischemic colitis, and IBD, although these disorders can have a similar endoscopic appearance. Colitis caused by significant inflammation from any one of many etiologies appears as focal patchy or segmental erythema, edema, loss of normal vascularity, erosions, or frank ulcerations with mucosal friability and or spontaneous hemorrhage. drome). The appearance of C. difficile infection may range from nonspecific changes in the rectum to the characteristic pseudomembranous exudative colitis. E. coli O157 H7 tends to mimic ischemic colitis, with patchy erythema, mucosal...

Lyme Disease

Lyme disease is characterized by three stages, not all of which occur in any given patient. The first stage, erythema migrans (EM), is the characteristic red, ring-shaped skin lesion with a central clearing that first appears at the site of the tick bite but may develop at distant sites as well (Figure 48-3). Patients may experience headache, fever, muscle and joint pain, and malaise during this stage. The second stage, beginning weeks to months after infection, may include arthritis, but the most important features are neurologic disorders (i.e., meningitis, neurologic deficits) and carditis. The third stage is usually characterized by chronic arthritis and may continue for years. Of note, there is an association between Borrelia species and distinct clinical manifestations.17-18 For example, B. garinii has been associated with up to 72 of European cases of neuroborreliosis.17,18

Generalized Reaction

Anaphylaxis and anaphylactoid reactions to drugs and other therapeutic agents have the same signs and symptoms of reactions as other agents that frequently cause allergic reactions (e.g., insect stings, foods, natural rubber latex). Reactions range in severity from mild pruritus, skin erythema and urticaria angioedema to more generalized and systemic reactions of laryngeal edema, rhinitis conjunctivitis, asthma, shock, and possibly death. IgE sensitization is involved with the following drug reactions p-lactam antibiotics, insulins, protamine, blood products, chymopapain, monoclonal antibodies, vaccines, natural rubber latex used in drug-delivery systems, ethylene oxide used to clean dialysis agents, or neuromuscular agents used in anesthesia induction. Anaphylactoid reactions may occur to sulfa RCM, ASA, NSAIDs, local general anesthetics, ACE-IN, vancomy-cin, chemotherapeutic agents, protamine, and monoclonal antibodies and blood products. Isolated drug fever typically occurs between...


Cellulitis generally appears following trauma, with appearance of local tenderness, pain, and erythema. The area involved is red, hot, and swollen, with non-elevated borders, and is sharply demarcated streptococcal cellulitis following surgery can develop within 6 to 48 hours, be associated with hypotension, and a thin serous discharge. Regional lymphadenitis and bacteremia are common and can cause thrombophlebitis. The infection can spread rapidly in patients with dependent edema. Recurrent episodes of cellulitis of the lower extremities due to streptococci non-group A can occur in patients whose saphenous veins have been removed for coronary bypass (2). The patients often have systemic manifestation of fever toxicity and chills and edema, erythema, and tenderness along the saphenous venectomy site.


Candida spp. can also invade the oral mucosa. Immunosuppressed patients, including very young infants, may develop oral candidiasis, called thrush. Oral thrush can extend to produce pharyngitis and or esophagitis, a common finding in patients with acquired immunodeficiency syndrome and in other immunosuppressed patients. Thrush is suspected if whitish patches of exudate on an area of inflammation are observed on the buccal (cheek) mucosa, tongue, or oropharynx. Oral mucositis or pharyngitis in the granulocytopenic patient may be caused by Enterobacteriaceae, S. aureus, or Candida spp. and is manifested by erythema, sore throat and possibly exudate or ulceration.


Concentrations of tetracyclines that are below the antibiotic threshold still have anti-inflammatory activity. Low doses of doxycycline and minocycine that do not affect bacterial growth decrease the production of neutrophil chemo-attractants by P. acnes (25,26). Subminimal inhibitory doses also retain the ability to inhibit inflammation in vivo and improve diseases such as acne, rosacea, and periodontitis (27-29). The side effect profile (Table 2) of doxycycline and minocycline also differs, most notably in the incidence of photosensitivity with doxycycline and the occurrence of hypersensitivity reactions with minocycline. Photosensitivity is very common at higher doses of doxycycline. The minocycline hypersensitivity reactions are uncommon and include urticaria, serum sickness-like reactions, and what has been termed a lupus-like reaction that in reality is probably not an activation of systemic lupus erythematosus but a generalized drug-induced reaction that resembles lupus (34).

Use And Side Effects

Dispensed and equally divided over two index fingers, which then dab the medication evenly onto opposite sides of the face and spread the medication into a thin layer until no visible product remains (21). Hands should be washed afterwards to avoid retinoid dermatitis (21). Application should first occur every other night for one to two weeks depending on the skin type so as to minimize the initial irritation that may otherwise discourage adherence to the treatment regimen (1,21). Oily skin is better able to tolerate the potential irritating effects of the retinoids and, as such, a shorter introductory period may be utilized (21). Non-comedogenic moisturizers can be used to minimize xerosis, erythema, and stinging (2). Patients should be instructed that as long as four to six weeks of use may be required before the onset of efficacy and that an initial flare in acne may occur following two to four weeks of use due to an accelerated evolution of preexisting microcomedones (3). Periodic...

Other Indications

Thalidomide was first reported to suppress erythema nodosum leprosum (ENL) in 1965 (35). Its beneficial effect was subsequently established in double-blind trials in which activity was noted in about 90 of patients (35-37). The use of several thalidomide analogs in patients with ENL has led to contradictory results (38-40). The mechanism of its action is not understood however, an antibacterial effect has been excluded (41). In addition, thalidomide does not inhibit the growth of M. tuberculosis in vitro (42). These observations suggest that the compound exerts its beneficial effects through a direct action on the immune or inflammatory system. This view is strongly supported by the suppression of GVHD observed with thalidomide in animal experiments (43-50) and in humans (51).

Side Effects

As discussed above, thalidomide has been used for the treatment of leprosy, graft versus host disease, rheumatoid arthritis, aphthous ulcers associated with AIDS, and various dermatologic disorders. The side effects of thalidomide have been well documented and they include drowsiness, constipation, peripheral sensory neuropathy, swelling of the limbs, erythema of the limbs, hair loss, fever, rash, and amenorrhea. Dizziness and mood changes occurred in 33-100 of all patients. Other frequent adverse effects are xerostomia, increased appetite, loss of libido, nausea, pruritus, and menstruation abnormalities have been occasionally observed. The most serious of these side effects is peripheral neuropathy. Its incidence has been estimated to be approx 1 in patients treated for lepra reactions (81), 12 in rheumatoid arthritis (65), 22 in prurigo nodularis (66), and 25 in patients with discoid lupus erythematosus (67). Based on electrophysiologic studies the incidence was estimated at 21...

Groin And Pubic Area

Large areas of demarcated macular erythema may indicate a fungal infection such as Tinea cruris (jock itch). This can be easily treated with topical anti-fungal creams but the nurse should instruct the patient on appropriate hygiene requirements to ensure eradication. Erythema of the pubic skin may also result from other dermatological conditions such as eczema, psoriasis, etc., and patients should be advised to see a general practitioner dermatologist for the management of any non-sexual skin condition. The prepuce (foreskin) if present, needs to be retracted, noting any phimosis (inability to retract the foreskin) (Swartz, 2002 Fuller & Schaller-Ayers, 2000). The examiner may want to retract the foreskin to determine its mobility (Swartz, 2002). Once the foreskin is retracted the glans penis and sub-prepuce skin can also be examined. It is important to note the presence of smegma (Swartz, 2002 Bellack & Edlund, 1992) or odour (Epstein et al., 2000). It is common to find mild...

Retinoid Types

Similarly, novel vehicles can allow controlled release of topical retinoids. Polyolprepolymer-2 is a material designed to help retain drug molecules in and on the skin when applied topically and has been shown to distribute tretinoin over time with equivalent efficacy to vehicle-free analogous formulations (16). The incorporation of tretinoin into this vehicle prevents rapid and excess percutaneous absorption of tretinoin, decreasing irritation (16). In vitro absorption studies, guinea pig irritation models, human patch test studies, and acne clinical trials of tre-tinoin gel and cream containing polyolprepolymer-2 demonstrate that the absorption of tretinoin during the first six hours of delivery is significantly less than that of standard preparations of tretinoin, but becomes similar after this time (16). Additionally, the total penetration of polyolprepolymer-impregnated tretinoin is less than vehicle-free tretinoin (16). Human patch tests demonstrated that both tre-tinoin gel and...

Physical Findings

The rash of AD typically begins as an erythematous, papulovescicular eruption that, with time, progresses to a scaly, lichenified maculopapular dermatitis. Weeping, crusting lesions of the head, neck and extensor surfaces of the extremities are common in infancy (see Fig. 1). These lesions may involve the entire body surface, yet the diaper area may be spared. The scalp is often affected in infants with some having features of concomitant scalp seborrhea. Because of intense pruritus and scratching, traumatic injury occurs over time, providing a portal of entry for secondary bacterial infection. The early erythema-tous lesions will frequently discolor after a while and become dry, hyperpigmented lesions as seen in chronic dermatitis of the older child. Older children and adults have a more flexural distribution of lesions (see Fig. 1). Lesions are typically dry, lichenfied maculopapular lesions. These lesions commonly remain intensely pruritic with resultant scratching, traumatic skin...


Canaliculitis, one of three infections of the lacrimal apparatus (see Table 56-1), is an inflammation of the lacrimal canal and is usually caused by Actinomyces or Propionibacterium propionicum (formerly Arachnia). Infection of the lacrimal sac (dacryocystitis) may involve numerous bacterial and fungal agents the major causes are listed in Table 56-1. Dacryoadenitis is an uncommon infection of the lacrimal gland characterized by pain of the upper eyelid with erythema and often involves pyogenic bacteria such as S. aureus and streptococci. Chronic infections of the lacrimal gland occur in tuber

The Spirochetes

She acquired the disease most likely from the bite of the nymphal form of the Ixodes tick infected with Borrelia burgdorferi. Even though symptoms were not manifest for a few weeks, her description of the initial lesion is consistent with erythema migrans (see Figure 48-3).
