Effective Home Remedy to Cure Eczema
Dermatitis herpetiformis (DH) is a condition characterized by pruritic papulovesicular skin lesions in which granular or linear IgA deposits are found at the dermal-epidermal junction 10 . The majority of patients with DH have the characteristic findings of celiac disease in small bowel biopsy specimens, although relatively few have GI symptoms. DH patients have similar HLA profiles to celiac patients and develop similar antibody elevations to gliadin and tissue transglutaminase (tTG). They are also at increased risk of malignancies as discussed later. Institution of a gluten-free diet will reverse both the skin and intestinal lesions, while standard therapies for DH such as dapsone improve only skin disease. It is not clear why only a small subset of celiacs has DH, while virtually all DH patients have the intestinal pathology of celiac disease.
Eczema includes atopic dermatitis, irritant dermatitis (due to water, detergents, chemicals, heat), and allergic contact dermatitis. The lifetime incidence of atopic dermatitis is 15-20 , with an equal distribution between the sexes. I. Atopic Dermatitis A. Atopic dermatitis usually first appears in infants 2-6 months of age. Infants and children have rashes on the shoulders, chest, abdomen, and back. Infants usually also have a rash on the face, scalp and around the ears. Children older than 18 months old tend to have rashes on the neck and antecubital and popliteal fossae. B. Atopic dermatitis usually resolves by puberty, but it sometimes recurs at times of stress. In adults it may appear as recalcitrant hand eczema or as a localized dermatitis. C. Acute lesions of atopic eczema are itchy, red, edematous papules and small vesicles which may progress to weeping and crusting lesions. Chronic rubbing and scratching may cause lichenification and hyperpigmentation. D. The classic triad...
Lesions, stemming from the action of beryllium on the skin, vary depending on the reactivity of the specific compound. When beryllium in solution penetrates the skin, contact dermatitis and ulceration can result (13,14). Similarly, dermal granulomas can result when this absorbed beryllium precipitates in the tissue under physiological pH, or when beryllium particles penetrate and become lodged in the skin (15-17). These granulomas do not heal until all traces of the metal have been excised (18,19). Subdermal injection of beryllium lactate in human volunteers resulted in intracellular granulomas (20).
Yarrow stops bleeding wounds and is used as a healing lotion and ointment. It also is used to reduce pain and heavy bleeding due to menstrual irregularities and helps to regulate the menstrual cycle. Yarrow enhances circulation, lowers blood pressure, and has an antispasmodic and anti-microbial effect. It also has an anti-inflammatory effect on skin and on mucous membranes. The most frequently reported side effect of Yarrow is dermatitis (skin rash). Yarrow should not be used for patients who have epilepsy or are pregnant.
Total serum IgE has been found to be markedly elevated in atopic dermatitis, with the serum IgE concentration correlating with the severity of the eczema and with the presence of allergic rhinitis, asthma, or both. Patients with atopic dermatitis without severe skin disease or accompanying asthma or hay fever may have normal IgE concentrations (45). Total IgE concentrations have been found to be markedly elevated in allergic bronchopulmonary aspergillosis.
In type IV, or delayed-type, hypersensitivity, the T-cell antigen receptor on T H1 lymphocytes binds to tissue antigens, resulting in clonal expansion of the lymphocyte population and T-cell activation with the release of inflammatory lymphokines. Clinical examples include contact dermatitis (e.g., poison ivy) and tuberculin hypersensitivity in tuberculosis and leprosy. Type IV reactions are divided into four subtypes. Type IVa1 reactions are mediated by CD4+ TH1 cells causing classic delayed-type hypersensitivity reactions, such as allergic contact dermatitis or tuberculin reactions. Type IVa2 reactions are mediated by CD4+ TH2 cells resulting in cell-mediated eosinophilic hypersensitivity as occurs in asthma. Type IVb reactions are mediated by cytotoxic CD8+ cells that mediate graft rejection and Stevens-Johnson syndrome. Type IVb2 reactions are mediated by CD8+ lymphocytes that can produce IL-5, resulting in cell-mediated eosinophilic hypersensitivity, usually in association with...
Smallpox once killed 40 percent of the people it infected, leaving survivors scarred and often blind. The smallpox virus is a DNA virus that is spread by nasal droplets from sneezing or coughing. Symptoms include fever, headache, backache, and development of a lumpy skin rash, shown in Figure 24-9. The World Health Organization (WHO) began a smallpox eradication program in 1967 through vaccination and the quarantine of sick people. The last naturally acquired smallpox case occurred in Somalia in 1977. In 1980, WHO declared that smallpox had been eradicated in nature.
Idiopathic pseudocystic chondromalacia occurs mainly in young and middle-aged adults. The gross appearance is one of a localised swelling of the auricular cartilage. A cut surface shows a well-defined cavity in the cartilage, which is distended with yellowish watery fluid 42 . Microscopically, the cavity shows a lining of degenerated cartilage on one surface (Fig. 8.2) on the other surface the cartilage is normal. It seems possible that the fluid is an exudate from undamaged perichondrial vessels that cannot be absorbed by the damaged perichondrial vessels. The association of this lesion with severe atopic eczema in four children 27 suggested that minor trauma from repeated rubbing of the auricle may play a part. Small pseudocysts of the elastic cartilage of the pinna may also be seen in the vicinity of inflammatory or neoplastic lesions of that region.
Clinically, patients may present with symptoms characteristic of a drug hypersensitivity reaction, including nonspecific skin rash, malaise, fever, and eosinophilia.120 More specific signs and symptoms referable to the heart include conduction abnormalities and tachy-arrhythmias, sudden death, and increased concentrations of cardiac enzymatic markers such as creatine kinase and the creatine kinase-MB isozyme.106,120,122, 123 Acute fulminant myocarditis with hemodynamic instability has also been described.106,116 The onset of hypersensitivity myocarditis after initiation of the offending medication is highly variable, with onsets hours to months after a medication is started.106,116
Hyperimmunoglobulin E syndrome Also known as Job's syndrome (ffl Old Testament) because of recurrent staphylococcal abscesses. Autosomal recessive inheritance, associated with atopic dermatitis and other autoimmune phenomena. Bacterial fungal infection, chronic dermatitis. Lab features 4 IgE, 4 eosinophils.
The incubation period, clinical features, and progression of the illness vary between organisms, but all share the triad of high fever, skin rash, and headache, with meningoencephalitis developing during the second week of the illness in a significant proportion of cases. Rocky Mountain spotted fever may occur without a rash a rash does not usually accompany Q fever and Mediterranean spotted fever is characterised by a distinctive eschar at the site of the bite.
Recently, the production of natural antibiotic peptides has emerged as an important mechanism of natural immunity in plants and animals. Defensins are diverse members of a large family of antimicrobial peptides, contributing to the antimicrobial action of granulocytes, mucosal host defence in the small intestine and epithelial host defence in the skin and elsewhere (see also Chapter 4 and 10). It has been proposed that a defensin deficiency may play a pivotal role in the aetiopathogenesis of Crohn's disease 11 , Moreover, defensins and other antimicrobial peptides such as cathelicidins, are found to be increased in patients with psoriasis and decreased in patients with atopic dermatitis. A deficiency in the expression of these antimicrobial peptides may account for the susceptibility of patients with atopic dermatitis to skin infection 12 , It has also been reported that pathologies characterised by severe neutropenia and frequent bacterial infections such as morbus Kostmann 13 and...
The apparent effective amelioration of inflammatory skin diseases such as psoriasis and atopic dermatitis by balneotherapy, using spa waters high in strontium (and selenium), prompted the investigation of possible modulatory effects of strontium on the production of cutaneous inflammatory cytokines (8). Effects on the induction of three cytokines in human keratinocytes namely, IL-1a, IL-6, and TNF-a were monitored in culture medium. The addition of strontium salts to both normal and inflammatory reconstituted skin in the medium had an inhibi-
Slightly faster in patients treated with IVIg 0 4 g kg daily for five days compared with those treated with PE.75 A large international trial compared PE alone with IVIg alone and PE followed by IVIg.76 A Cochrane review including these and other smaller trials concluded that there is no significant difference in outcome between the treatments.77 Although IVIg is expensive, it is not much more expensive than PE and it is more widely available and simpler to give. Although there was a trend towards more rapid recovery in the patients who received combined treatment with PE followed by IVIg, this was not significant, and not sufficient to justify the extra inconvenience, risk, and cost.76 The usual regimen is 0 4 g kg of intravenous immunoglobulin by intravenous infusion daily for five consecutive days. There is a small risk of anaphylaxis which is greatest during the first 20 minutes of each infusion. There is also a concern about exacerbating pre-existing renal failure. Side effects...
P.S.--I have kept back for a day the enclosed owing to the arrival of your most interesting letter. I knew it was a mere chance whether you could inform me on the points required but no one other person has so often responded to my miscellaneous queries. I believe I have now in my greenhouse L. trigynum (155 7. Linum trigynum.), which came up from seed purchased as L. flavum, from which it is wholly different in foliage. I have just sent in a paper on Dimorphism of Linum to the Linnean Society (155 8. On the Existence of the Forms, and on their reciprocal Sexual Relation, in several species of the genus Linum.-- Journ. Linn. Soc. Volume VII., page 69, 1864.), and so I do not doubt your memory is right about L. trigynum the functional difference in the two forms of Linum is really wonderful. I assure you I quite long to see you and a few others in London it is not so much the eczema which has taken the epidermis a dozen times clean off but I have been knocked up of late with...
Furthermore, many inflammatory skin diseases can involve the periorbital region. Periorbital eczema may be an expression of a constitutional disease, an irritant or allergic dermatitis. Other inflammatory dermatoses that can involve the eyelids are seborrheic dermatitis, psoriasis, rosacea and dermatomyositis. Other causes of inflammation of the eyelids include bacterial, fungal and viral infections.
Allergic reactions (contact dermatitis) have occurred with topical use in sensitized individuals, and ingestion may also produce allergic reactions in people with preexisting allergies to members of the Compositae family. Feverfew has caused contractions in term pregnancy and has been implicated in cattle abortions and so should be avoided in pregnancy and lactation. A feverfew withdrawal syndrome consisting of joint pain and muscle stiffness may occur following abrupt discontinuation. Theoretically, because of its antiprostaglandin effects, feverfew should not be coadministered with anticoagulants or antiplatelet drugs.
The most common cutaneous illness associated with abnormal processing of HPV is atopic dermatitis, although some studies have not supported an increased incidence. A recent study from the United Kingdom demonstrated that cervical cancer is more common in eczema patients and patients who acquire common warts. However, this study suggests that non-atopic eczemas, such as seborrheic dermatitis, may be the type associated with cervical cancers, as hay fever, an illness commonly co-morbid with atopic eczema, was not statistically correlated to cervical cancer 31 .

Current studies suggest that vitamin E deficiency is common in US toddlers 88 . Vitamin E supplementation enhances proliferative response in vitro 89 and improves IL-2 cytokine response 90 . Vitamin E deficiency causes reduced transferrin receptor internalization in the mouse, which suggests restriction of intracellular iron stores that would be needed for cellular function and proliferation 91 . Vitamin E may influence T cell function by downmodulating PGE2. Improvement in eczema and reduction in serum levels of IgE in atopic subjects has recently been reported 92 . A recent study has shown that antioxidant deficiency is common in a very large cohort of CF patients. Carotenoid and vitamin E deficiencies were found to occur early in the course of the disease and antioxidants were observed to decrease with bronchial infection 93 .
This may occur with chronic neurodermatitis, less frequently with other skin disorders such as scleroderma, poikiloderma, and chromic eczema. Characteristic signs include an anterior crest-shaped thickening of the protruding center of the capsule (Fig. 7.11).
The side effects of paclitaxel include hypersensitivity reactions (such as shortness of breath or skin rash), myelosupression, peripheral neuropathy, cardiac rhythm disturbances, joint or muscle pain, diarrhoea, nausea and vomiting, or hair loss. Patients often receive premedication before receiving paclitaxel to prevent possible allergic reactions.
During the 18th century, mistletoe was applied for weakness of the heart and oedema. These indications have been recorded in the homeopathic materia medica until today (Boericke, 1992). By the end of the 19th century, mistletoe was rejected by the scientists as a folklore remedy. The only remaining acceptable application was the mistletoe-containing ointment, Viscin, which was a yellowish bird-lime. Viscin was reported to be effective for eczema, ulcers of the feet, burns, and granulating wounds (Riehl, 1900 Klug, 1906). In a German encyclopaedia from 1934, it was stated that mistletoe did not contain clinically relevant compounds (Oestergaards Lexicon, 1934). However, an encyclopaedia from 1962 reports the historical use of mistletoe as a cure for epilepsy, convulsions, and worms (Duden Lexicon, 1962). The scientific interest on mistletoe awakened in the 20th century, as Gaultier (1907, 1910) investigated the effect of oral or subcutaneous applications of fresh Viscum album L....
Extensive evidence has accumulated that may define the underlying immunologic basis for the atopic phenotype, that is, individuals with allergic asthma, allergic rhinitis, and atopic eczema (24). The atopic condition can be viewed as a TH2 lymphocyte-driven response to allergens of complex genetic and environmental origins (36). The reciprocal action of IL-4 and IFN-g on IgE production led to several studies on the T-cell origin of these cytokines. Mosmann and Coffman ( 37) described two distinct types of helper T cells in murine systems and defined them as TH1 or TH2 cells by the pattern of cytokine secretion. TH1 cells produced IL-2, IFN-g, and lymphotoxin. TH2 cells produced IL-4, IL-5, IL-6, and IL-10.
Allergic contact dermatitis and even burns from prolonged skin contact with the cloves have been reported. Systemic allergy with bronchospasm or hives from ingestion occurs rarely. There is some concern that chronic high doses may lead to decreased hemoglobin production.
Affects approximately 2 of infants younger than 2 years of age. Clinical spectrum ranges from immediate-type reactions, including urticaria and angioedema, to intermediate and late-onset reactions, such as atopic dermatitis, gastroesophageal reflux, enterocolitis, and proctitis.

Systemic diseases of the skin (e.g., psoriasis, lupus erythematosus, scleroderma) can affect the ear canal and eventually cause external canal obstruction. One important feature of psoriasis is that mild trauma to surrounding skin induces lesions localized to the area of injury.9 Therefore, patients with psoriasis in or near the ear canal should be asked to avoid manipulation of the lesions, so as to prevent stenosis. Cutaneous (contact dermatitis) reactions to shampoos, medications, and foreign material in the ear canal can be severe and may require rapid medical attention to prevent scarring and stenosis of the soft tissue of the canal.
The initial hypothesis of an immunological basis for idiosyncratic reactions came from the clinical presentation delayed onset, fever, and the common occurrence of systemic eosinophilia. Histopathological evaluation of idiosyncratic hepatopathies often reveals infiltrating lymphocytes and plasma cells as well as bridging necrosis reminiscent of viral hepatitis. A skin rash is often part of the clinical presentation and histopathological examination reveals lesions consistent with immune-mediated skin disease. Serum sickness-like reactions, including polyarthritis, have also been reported. On re-exposure, there is often, although not always, a shorter period of time to recurrence of clinical signs. This general clinical picture was consistent with an immunological basis, particularly for the systemic hypersensitivity syndrome reactions associated with drugs such as the sulfonamides and aromatic anticonvulsants (Cribb et al. 1996 Shear and Spielberg 1988).
Some viral diseases involve the upper alimentary system but produce more dramatic symptoms elsewhere in the body. For example, measles produces Koplik's spots in the mouth, a dramatic skin rash, and respiratory symptoms chickenpox causes oral blisters and ulcers, but a striking skin rash infectious mononucleo-sis can cause multiple oral ulcers and bleeding gums, but impressively enlarged lymph nodes and spleen. In this section, we focus on herpes simplex, with its characteristically painful oral ulcers, and mumps, with its enlarged, painful parotid glands. measles, p. 549 chickenpox, p. 546 infectious mononucleosis, p. 726
2.5 Disorders of the Skin and Margin of the Eyelid 2.5.1 Contact Eczema Etiology Contact eczema is caused by an antigen - antibody reaction in patients with intolerance to certain noxious substances. Cosmetics, adhesive bandages, or eyedrops and eye ointments are often responsible, particularly the preservatives used in them such as benzalkonium chloride. 2.5 Disorders of the Skin and Margin of the Eyelid Contact eczema. -
Risk, and reduction of body fat. y-Linolenic acid (GLA) is used for suppression of inflammation and in the treatment of diabetic neuropathy, atopic eczema, and certain cancers, such as malignant human brain glioma. a-Linolenic acid (ALA) has a broad range of health benefits it inhibits the production of eicosanoids, alters the production of several prosanoids, reduces blood pressure in hypertensive patients, and lowers triglycerides and cholesterol. Diets containing ALA inhibit lymphocyte proliferation, retard tumor growth, and may also play a role in metastasis.8
According to Benito et al. (1996) there were no cases described in medical literature of systemic allergic reactions due to oregano before their report on three cases. Benito et al. (1996) concluded that plants belonging to the Labiateae family seem to show cross-sensitivity on the basis of clinical history and in vitro and in vivo test results. However, already in 1993 Futrell and Rietschel have published results of their patch tests of spice allergies, and 4 of their 55 patients with suspected contact dermatitis showed positive results with oregano.
Care should be taken in transferring patients from systemic to aerosol corticosteroids, as deaths due to adrenal insufficiency have been reported. In addition, allergic conditions, such as rhinitis, conjunctivitis, and eczema, previously controlled by systemic corticos-teroids, may be unmasked when asthmatic patients are switched from systemic to inhaled corticosteroids. Caution should be exercised when taking cortico-steroids during pregnancy, as glucocorticoids are terato-genic. Systemic corticosteroids are contraindicated in patients with systemic fungal infections.
Tranexamic acid has a six- to tenfold higher molar potency compared with e-aminocaproic acid and is generally preferred for clinical usage, although routes of administration, effectiveness, limitations, and side-effects of the two compounds are similar. Tranexamic acid is available as 500-mg tablets (Cyklokapron, Pharmacia, United Kingdom), a syrup, or a colorless solution (5 ml contains 500 mg tranexamic acid) for intravenous infusion. Tranexamic acid is rapidly absorbed from the gastrointestinal tract with a serum half-life of 2 h, and is rapidly excreted unchanged in the urine with greater than 90 per cent elimination within 24 h. The inhibitory effect on fibrinolysis lasts for 7 to 8 h compared with less than 3 h for e-aminocaproic acid. As urine levels are considerably higher than plasma levels, reduced doses provide effective control of urinary tract bleeding. Recommended adult dosages are 500 to 1000 mg three times daily orally or a similar dose by slow intravenous injection (1...
Warts are a very common illness worldwide. In the United States, children are the most likely targets of the common wart viruses. Warts follow acne and atopic dermatitis in frequency of diagnosis in pediatric dermatology clinics 12, 13 . It is thought that 10-20 of children will at sometime be infected with warts 1, 3, 14 . The peak incidence of disease varies from study to study with some studies showing a peak age grouping of 8-9 years and others pointing to a peak age range between 12 and 18 year olds 1, 14-16 . The incidence of plantar warts has doubled from its incidence in 1968, which was then found in 1.8-2.9 of primary and secondary school children, to currently 4.5 16 . Females and males are equally affected by HPV infections. The leading sites of HPV infection are the extremities, face and body. Hand warts are often transferred to other cutaneous sites including the lips, nose, and face, via autoinoculation. Autoinoculation is generally the route of disease extension or...
Eczema is seen in association with milk-protein allergy. Cutaneous hemangioma or telangiectasia suggests internal vascular anomalies. Petechia or bruising may suggest liver disease or coagulopathy. Purpura is seen with the vasculitis of HSP. Erythema nodosum frequently is found with inflammatory bowel disease.
Harmful effects produced by the mechanisms of cell-mediated immunity are referred to as delayed hypersensitivity. The name reflects the slowly developing response to antigen reactions peak at 2 to 3 days rather than in minutes as in immediate hypersensitivity. As would be expected with cell-mediated responses, T cells are responsible and antibodies are not involved. Delayed hypersensitivity reactions can occur almost anywhere in the body. They are wholly or partly responsible for contact dermatitis (such as from poison ivy and poison oak), tissue damage in a variety of infectious diseases, rejection of tissue grafts, and some autoimmune diseases directed against antigens of self.
The adverse effects of valacyclovir and acyclovir are similar. Toxicity is generally minimal, consisting largely of headache, nausea, and diarrhea. Less frequently observed are skin rash, fatigue, fever, hair loss, and depression. Reversible renal dysfunction (azotemia) and neurotoxicity (tremor, seizure, delirium) are dose-limiting toxicities of intravenous acyclovir. Adequate hydration and slow drug infusion can minimize the risk of renal toxicity.
Dermatitis herpetiformis showing polymorphonuclear leukocytes at the tips of the papillary corium Microscopically, the lesions of dermatitis herpetiformis show polymorphonuclear leukocyte microabscesses in the tips of the papillary corium (Fig. 3.4). Initially, neutrophils predominate, but as the microabscesses enlarge eosinophils become more conspicuous. The mi-croabscesses eventually fuse to form visible blisters that frequently rupture leaving superficial ulcers. Direct immunofluorescence shows granular deposits of IgA in the BMZ of the dermal papillae, in both affected and adjacent normal mucosa.
Catecholamine metabolites represent the most sensitive and specific tumor markers. While the determination of vanillylmandelic acid (VMA) and ho-movanillic acid (HVA) in a clean void urine sample is considered essential, the additional value of dopamine is less clear. The simultaneous measurement of urinary creatinine permits reliable VMA and HVA estimates in spot urine samples avoiding the uncomfortable 24-h urine collection. The determination of VMA, HVA, and dopamine in serum samples may be useful in some instances, but is 10-15 less sensitive. The usefulness of catecholamine metabolites as early markers of recurrence may be limited. In one study only 54 of patients demonstrated abnormal values at the time of recurrence (Simon et al. 2003). Using HPLC or mass spectrometry, the number of false-positive values is substantially reduced. False positives (predominantly HVA levels) were observed during a large screening program after massive apple juice intake, with active...
Type IV delayed hypersensitivity, also called T-cell mediated contact dermatitis, allergic contact dermatitis, and delayed hypersensi-tivity, directly involves the immune system, in contrast to irritant dermatitis. Among the immunologic responses to latex, 84 percent are Type IV.28 This type of reaction is usually a response to the chemical additives used during the manufacturing process, specifically the accelerators, rather than to the latex proteins themselves. The resulting skin reactions are similar to those caused by poison ivy. Like poison ivy, the skin rash usually appears six to 72 hours after initial contact and may progress from a mild dermatitis to oozing skin blisters. It is important to recognize that not all patients with Type IV reactions progress to Type I reactions. However, 79 percent of Type I patients previously had Type IV symptoms.29 Latex exposure can occur as a result of contact with the skin or mucous membranes or by...
Nickel is widely employed in modern industry in conjunction with other metals for the production of alloys for coins, jewellery, and stainless steel it is also used for plating, battery production, as a catalyst, etc. Workers are exposed to nickel at all stages of the processing of nickel-containing products through air, water or skin contacts. For example, the exposure to airborne nickel-containing particles has long been known to cause acute respiratory symptoms ranging from mild irritation and inflammation of the respiratory system to bronchitis, asthma, and pulmonary fibrosis and edema. Another well-known adverse effect is allergic contact dermatitis. The indicated health problems caused by nickel exposure are mediated by an active change in the expression of genes that control inflammation, the response to stress, cell proliferation or cell death. All this and more is covered in Chapter 16. However, the most serious health effects beyond nickel toxicity relate to carcinogenesis...
Allergic rhinitis (hay fever) is part of an inherited syndrome, which may also manifest as atopic eczema and asthma. In allergic rhinitis, airborne particles, such as grass pollens, moulds and animal allergens, are deposited on the nasal mucosa giving rise to acute and chronic reactions. Allergens combine with the IgE antibodies produced by the plasma cells of the nasal mucosa, which are avidly bound to the Fc-epsilon receptors on mast cells. This triggers degranulation of mast cells and releases the inflammatory mediators of the type I hyper-sensitivity reaction, causing rhinorrhoea and nasal obstruction. Microscopically, the nasal mucosa shows numerous eosinophils, abundant plasma and in some cases an increased number of mast cells. There is goblet cell
Endophthalmitis is one of the most serious complications that can occur following infantile cataract surgery 46 . It has been reported to have a prevalence of 7 10,000 surgeries, which is similar to the prevalence reported following cataract surgery in adults 20 . In most cases, it is diagnosed within several days of cataract surgery. It is most frequently caused by Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, and Streptococcus viridans. Nasolacrimal duct obstruction, periorbital eczema, and upper respiratory infection are important risk factors for the development of postoperative endophthalmitis. For this rea
Most pinworm infections are asymptomatic. When symptoms occur, it is usually in the form of itching from the anus area. Itching is usually worse at night when migration of females and egg deposition occurs. The degree of symptoms are related to the parasite load. Pruritus at night may disturb the sleep for affected children and certainly are an annoyance in the daily life of the affected family. The medical importance of the disease is otherwise small. Some worms may find their way into adjacent orifices, most commonly the female genitourinary tract, producing irritative symptoms such as vulvovaginitis and cystourethritis. Case reports of extra-intestinal infestation by enterobius in the peritoneal cavity, endometrium, lungs, liver, and other organs occur, but mainly from developing countries where high parasite loads could be expected in many patients (Arora et al. 1997 al-Rufaie et al. 1998). Secondary bacterial infections after itching have been reported in children with atopic...
Mercury compounds have been administered for medical purposes since the earliest times, applied directly to the skin, or given by mouth, and more recently by intramuscular or intravenous injection. Hypersensitivity (i.e., contact sensitivity) to mercury as a consequence of medicinal administration was first described in 1895 (93). Like other transition group elements and highly electropositive heavy metals, such as lead and cadmium, mercury can act as a coordination center for electronegative groups (SH groups and disulfide bridges, cysteinyl and histidyl residues) present in proteins, purines, and pteridines. Such complexation can cause conformational changes and hence immunogenicity (94). Hypersensitivity reactions to host proteins haptenized by mercury following skin contact or systemic exposure can be (a) of type I or anaphylactic, mediated by immunoglobulin E (IgE) (presenting clinically as urticaria) (b) of type III or Arthus reactions involving antigen-antibody complexes with...
Sinus problems, hay fever, bronchial asthma, hives, eczema, contact dermatitis, food allergies, and reactions to drugs are all allergic reactions associated with the release of histamine and other autocoids, such as serotonin, leukotrienes, and prostaglandins. Histamine release is frequently associated with various inflammatory states and may be increased in urticarial reactions, mas-tocytosis, and basophilia. Histamine also acts as a neu-rotransmitter in the central nervous system (CNS). Upon release from its storage sites, histamine exerts effects ranging from mild irritation and itching to ana-phylactic shock and eventual death.
Carbamazepine exerts its anticonvulsant activity through its own action on voltage sensitive sodium channels and those of its relatively stable 10-11-epoxide. The compound shows a number of potential toxicities including skin rash, hepatic necrosis and teratogenicity. It is possible the 10-11-epoxide is the causative agent, but struc- tural studies 9 suggest other epoxide metabolites of the aromatic ring may be responsible in part. Oxcarbazepine (Figure 8.7) is a related drug that cannot form the 10-11-epoxide and owes part of its activity to its hydroxyl metabolite. Oxcarbazepine is much less teratogenic in animal models and shows a lower preponderance of skin rash 8,10 .
Observations made in conjunction with the treatment of affective disorders showed that lithium taken orally causes side effects involving various systems of the body, including the skin it can both aggravate preexisting dermatological conditions, and have positive dermatological effects in cases of eczema (contact
Local irritation, such as burning, pruritus, and irritant contact dermatitis, is common following topical application. Major side effects seen after systemic administration include dyslipidemia, leukopenia, liver function test abnormalities, and possibly development of cataracts. Unlike other systemic retinoids, oral bexarotene causes thyroid abnormalities in approximately half of patients, which may necessitate treatment for hypothyroidism. Bexarotene is teratogenic and should not be prescribed in topical or oral form to women of childbearing potential unless a negative serum pregnancy test has been obtained and the patient agrees in writing to use two effective forms of contraception from 1 month before to 1 month after treatment.
While admission to the ICU will depend on clinical need, it is important that other patients and staff are not exposed to unnecessary infection risk. Patients with unexplained diarrhea, infected eczema, or communicable diseases, or who are known or suspected carriers of multiple antibacterial-resistant bacteria, should be admitted to source isolation until cleared of transmission risk.
Pimecrolimus (SDZ ASM 981, Elidel) is another recently approved macrolide immunosuppressant that acts by inhibiting calcineurin and blocking the release of proinflammatory cytokines from T lymphocytes. The parent compound, ascomycin, was originally isolated from Streptomyces hygroscopicus var ascomyceticus. Like tacrolimus, pimecrolimus is approved for the topical treatment of moderate to severe atopic dermatitis that is refractory to other therapies. Transient local irritation is a common side effect.
Numerous theories have been investigated to identify the etiology of vulvar vestibulitis. Chronic bacterial and viral infections have been the strongest focus of study. Candida, chlamydia, gonorrhea, mycoplasma, contact dermatitis and other allergic responses, hormonal reaction, and psychosomatic causes have also been considered. Despite these extensive investigations, the etiology remains unclear and may be multifactorial.
The adverse effects with which stavudine is most frequently associated are headache, diarrhea, skin rash, nausea, vomiting, insomnia, anorexia, myalgia, and weakness. Peripheral neuropathy consisting of numbness, tingling, or pain in the hands or feet is also common with higher doses of the drug. Significant elevation of hepatic enzymes may be seen in approximately 10 to 15 of patients. Lactic acidosis occurs more frequently with stavudine than with other NRTIs. Viral resistance to stavudine may develop, and cross-resistance to zi-dovudine and didanosine may occur.
Sargramostim (GM-CSF, Leukine, Prokine) is a human recombinant granulocyte and macrophage colony-stimulating factor that stimulates the production and potentiates the function of both granulocytes and macrophages from hematopoietic progenitor cells. It is used to accelerate bone marrow repopulation after high-dose chemotherapy, radiation therapy, and bone marrow transplantation. Adverse effects associated with sargramostim use include bone pain (similar to that of filgrastim), fatigue, fevers, skin rash, malaise, and fluid retention.
This is a disorder caused by the spirochaete Borrelia Burgdorferi, characterised by relapsing and remitting arthralgia associated with a characteristic skin rash (erythema chronicum nigrans) and neurological features. The organism, related to the treponemes, is prevalent throughout Europe and North America and is carried by ixodes ticks. Tick bite - flu-like symptoms, arthralgia and skin rash (erythema chronicum nigrans). Treatment with antibiotics is usually curative.
This condition presents at puberty and has been found in association with systemic disorders like Marfan's syndrome, Down's syndrome 52, 88 , neurofibromatosis, Ehlers-Danlos syndrome 56, 94, 129 and atopic dermatitis 93, 109, 119 . It can also be seen in combination with ocular disorders like aniridia, cataract and retinitis pigmentosa 11, 33, 53 . A progressive, non-inflamma
Atopy is an underlying disease syndrome which has been consistently connected with dermatophytosis. A high proportion of chronically infected individuals, over 40 in some surveys, have hay fever, asthma, or atopic eczema either on personal or family history (Hay, 1982 Jones et al., 1973). In addition a high proportion of individuals seen in dermatological clinics with peripheral dermatophyte infection either have negative or immediate-type hypersensitivity to dermatophyte antigens on intradermal testing. Increased prevalence of immediate-type responses to intra-dermally injected antigens is also a feature of atopic subjects. There is also evidence that some individuals with persistent dermatophytosis may also have sensitivity to environmental moulds suggesting a modified (atopic) immunological response to a family of antigens.
The skin is the site of several common disorders that include acne vulgaris, psoriasis, eczema dermatitis, contact dermatitis, drug-induced dermatitis, and burns. Some disorders result from viral infections such as herpes simplex and herpes zoster. Some result from fungal infections such as tinea pedis (athlete's foot) and tinea capitis (ringworm).
Candida albicans is the most frequently isolated fungal pathogen in humans however, its role in allergic disease is relatively minimal. A possible role of this yeast in allergic disease is best appreciated through studies with asthmatic individuals. In studies with 149 asthmatic patients, 48 were positive for C. albicans on skin tests. Of these, 77 had positive inhalation provocation test results, with most demonstrating positive RAST results to C. albicans(138). Two major allergens have been cloned, and one of these has been identified as a subunit of alcohol dehydrogenase ( 139,140). The other major allergen appears to be enolase, which cross-reacts as noted before. Candida also secretes an acid protease, which produces IgE antibodies in 37 of Candida-allergic patients (141). Candida sensitivity is also associated with eczema related to infection with the human immunodeficiency virus (142).
Following the introduction of tympanoplasty in the early 1950s by Wullstein16 and Zollner,17 all surgeries used an overlay graft. Wullstein's article, ''Tympanoplasty as an Operation to Improve Hearing in Chronic Otitis Media and Its Results,'' set the stage for this operation to improve hearing and protect the middle ear from the outside environment. At that time, this operation consisted of full-thickness and split-thickness skin grafts. By the end of the decade, graft eczema, desquamation, and a poor long-term take rate had prompted many surgeons to seed alternate grafting materials and techniques.18 In 1956 Sooy19 had reported the use of canal skin pedicle graft to close marginal perforations. In 1958 House and Plester, working independently, began using canal skin as a free overlay graft.20,21 In 1959 Shea, Austin, and Tabb, working independently, employed vein as an undersurface graft to repair tympanic membrane perforations.22 24 The vein graft tended to atrophy over a few...
Frequent diaper changes gentle, thorough cleansing of area and application of lubricants and barrier pastes is usually all that is needed. Occasionally a short course of low-potency steroids hastens resolution. infection, but significant for pruritus in the perineum. Physical exam showed a well-appearing girl in no acute distress. There was no back pain and no abdominal tenderness. Significant erythema of the labia minora and vulva was noted. There was no appreciable discharge. Urinalysis was normal. Patient was diagnosed with contact dermatitis and started on lubricant ointment 4 times a day. Her symptoms resolved in 5 days.
Morphologically, Sezary cells are either small (approximately 8 m) or larger (approximately 15 to 20 im), the latter reportedly reflecting a block in the cell cycle between G1 and S phase.239 Sezary cells contain a hyperchromatic convoluted or cerebriform nucleus, which is more serpentine than the convoluted nuclei in T-cell lymphoblastic lymphoma (Plate 3-2Q). Similar-appearing peripheral T cells with cerebriform nuclear contours may rarely be found in patients with non-Hodgkin's lymphoma of the diffuse mixed cell type,246 although they generally are pathognomonic for CTCL. Sezary cells have also been observed in the skin and blood of patients with a number of benign dermatoses, including erythrodermic eczema, psoriasis, lichen planus, and actinic reticuloid.247 However, while Sezary
Dermatitis is a skin eruption that is caused by medications (drug-induced dermatitis) or by a chemical agent coming in touch with the skin (contact dermatitis). Contact dermatitis, also called exogenous dermatitis, is caused by chemical or plant irritation and is characterized by a skin rash with itching, swelling, blistering, oozing, or scaling at the affected skin sites. The chemical contact may include cosmetics, cleansing products (soaps and detergents), perfume, clothing, dyes, and topical drugs. Plant contacts include poison ivy, poison oak, and poison sumac. Nonpharmacological treatment of contact dermatitis includes avoiding direct contact with the causative irritant. The patient should use protective gloves and clothing if the chemical agent is associated with his or her employment. At the first sign of contact dermatitis, clean the skin area immediately. Patch testing may be needed to determine the causative factor. Apply wet dressings containing Burow's solution (aluminum...
The protective skin barrier is a vital factor in preventing the HPV from accessing the basal layer of the skin. Skin diseases in which barrier is impaired (e.g., atopic dermatitis and Darier's disease) predispose to HPV infection. However, many of these conditions also feature abnormal cutaneous immunity and thus the skin barrier may not be the only factor influencing the risk of HPV infections. Innate immunity to warts is that aspect of the immune system that works actively against pathogens without prior exposure. These include nitric oxide production, mobilization of natural killer cells and neutrophils, the phagocytic response, and the local production of cytokines and chemokines.
Chickenpox and shingles are caused by the same varicella-zoster herpesvirus. The virus multiplies in the lungs and travels to blood vessels in the skin. The symptoms of chickenpox include fever and skin rash. The virus is spread through direct contact with the skin rash and through the air. After recovery, a person has lifelong resistance to reinfection. The virus, however, can sometimes stay in nerve cells as a provirus. The virus can later cause a disease called shingles. The shingles rash, shown in Figure 24-5, can shed new chickenpox viruses and infect susceptible children and adults.
Tacrolimus is a macrolide lactone originally derived from Streptomyces tsukubaensis. Although structurally unrelated to cyclosporine, tacrolimus has a very similar mechanism of action that is, it blocks the production of proinflammatory cytokines by T lymphocytes by inhibiting calcineurin. Tacrolimus, however, appears to be 10 to 100 times as potent as an immunosuppressive. Oral tacrolimus (FK506) is used for prevention of organ rejection in recipients of renal and hepatic transplants. A topical formulation (Protopic) has recently been approved for treatment of moderate to severe atopic dermatitis in children and adults who have not responded to other therapies. Levels of systemic absorption are low even when applied to a relatively large body surface area. Local irritant reactions (burning, stinging, erythema) are a common side effect, but these usually resolve within the first few days of treatment. The major benefit of topical tacrolimus over topical corticosteroids is that...
Recipient pregnancy monitoring there needs to be some forethought about recipient selection. Multiparous cows are superior to heifers in their ability to calve per vaginum, especially with the increased birthweight associated with cloning (Table 1 15 ). It is also wise to choose larger-framed cows. Suitable cows in the authors' experience are either Friesian or Friesian crossed with Hereford. There are some drawbacks, however, with using a high milk-producing breed, such as the Friesian, if the suckle rearing system is used, for example, the risk of mastitis. It is imperative that the cows are of good temperament because a lot of handling is involved in the management of clone-bearing recipients. The recipients need to be fed suitable planes of nutrition throughout gestation to prevent metabolic complications and calving difficulties. In a pastoral-based system, it can be difficult to avoid overfeeding when the number of animals in a group is small. Local disease risks need to be...
A few individuals may be allergic, or hypersensitive, to a drug. This allergy may arise because of a prior contact with a particular substance called an allergen (it may even be the drug itself). This acquiring of an allergy is called sensitization. You should understand that the symptoms of an allergy are not related to the ordinary effects of the drug. Allergic reactions to a drug may range from a mildly irritated skin rash to anaphylaxis (a fatal shock). It has been shown that penicillin, a widely prescribed antibiotic, produces varying types of allergic reactions in from 1 to 10 percent of the patients who are administered the drug.
Safety testing of skin care products is an important prerequisite to successful market launch for two-in-one, three-in-one, and all-in-one products. This is because the skin, as the largest organ of the body, is an extraordinarily complex and dynamic organ. To maintain normal homeostasis with the internal and external mileu of the body, the stratum corneum along with the major epidermal cell types i.e., keratinocytes, melanocytes ( pigment cells ), Langerhans cells (the immune macrophage of skin), Merkel cells (resevoir for skin neural peptides), and T-lym-phocytes, plus a myriad of cutaneous cytokines determine whether perturbation to the skin and or its appendages during application of cosmetic skin care products results in the potential development of either irritant or allergic contact dermatitis. Furthermore, one needs to evaluate the more common dermatosensorial safety issues (e.g., itching, burning, tingling, stinging phenomena) that may lead to barriers for ultimate marketing...
Reversible airways disease does not always represent asthma. Wheezing may persist for weeks after an acute bronchitis episode. Patients with chronic obstructive pulmonary disease may have a reversible component superimposed on their fixed obstruction. Etiologic clues include a personal history of allergic disease, such as rhinitis or atopic dermatitis, and a family history of allergic disease. B. Physical examination. Hyperventilation, use of accessory muscles of respiration, audible wheezing, and a prolonged expiratory phase are common. Increased nasal secretions or congestion, polyps, and eczema may be present. The chest and lungs should be assessed for wheezing.
The incidence of adverse effects with hydroquinone increases in proportion to its concentration. A relatively common side effect is local irritation, which may actually exacerbate the discoloration of the skin being treated. Allergic contact dermatitis occurs less commonly. A rare but more serious complication is exogenous ochronosis, in which a yellow-brown pigment deposited in the dermis results in blue-black pigmentation of the skin that may be permanent.
The introduction of herceptin (Trastuzumab) into clinical practice for the treatment of breast cancer marks a major advance in the use of monoclonal antibody cancer therapy. Herceptin is a humanized antibody directed against the HER-2 antigen that is overexpressed on the tumor cell surface in approximately 25 of breast cancer patients. HER-2 neu erbB2 overexpression marks an aggressive estrogen receptor-negative form of breast cancer. Therefore, a therapeutic agent selective for this target is particularly valuable. Herceptin is administered by intravenous infusion and in conjunction with paclitaxel can extend survival in patients with HER-2 neu erbB2 overexpressing meta-static breast cancer. Herceptin use is associated with infusion- related hypotension, flushing and bronchocon-striction, and skin rash but no bone marrow toxicity. Herceptin appears to sensitize patients to cardiotoxic-ity, an important concern in patients also receiving doxorubicin.
