A11. UV-related skin hazards: allergic photodermatitis

JOURNAL OF COSMETIC DERMATOLOGY, Issue 2 2002
Paolo Pigatto
Cases of dermatitis induced by exposure to ultra-violet radiation are increasingly encountered in clinical practice, with contact allergic photodermatitis accounting for about 10% of cases. Its frequency seems to be increasing, not only as a result of the increased use of cosmetic products and contact with some of the materials of working processes, but above all because of the greater exposure to both natural and artificial sources of UV radiation. Many substances have been defined ,photo-allergising' but their exact prevalence has varied over the years with the introduction and use of new substances in cosmetics and pharmaceutical products. For these, and other reasons, there are few studies concerning the prevalence and incidence of contact allergic photodermatitis in Italy. A total of 2160 patients with clinical histories suggestive of photoallergic contact dermatitis were seen. All patients underwent photopatch tests with haptens proposed by the Gruppo Italiano Ricerca Dermatiti da Contatto plus other substances suggested by each patient's history. 518 patients (24%) were positive to at least one test substance of the standard series or to added substances. Typical photoallergic reactions were seen in 423 subjects, representing 19.5% of the total population. Topical drugs are the substances most frequently involved in photodermatitis. The incidence in our population was about equal for antimicrobial agents, additives to fragrances, and fragrances themselves. Other allergens frequently found were sun screening agents which were the second group of haptens with clear-cut relevance. [source]


Ovarian carcinoma screening in women at intermediate risk

CANCER, Issue 2 2005
Impact on quality of life, need for invasive follow-up
Abstract BACKGROUND Women with family histories suggestive of an increased risk of ovarian carcinoma who have not had a deleterious BRCA1 or BRCA2 mutation identified are commonly suggested to consider ovarian carcinoma screening with transvaginal ultrasound and/or assessment of CA 125 levels. Limited information is available regarding the impact of this approach on either quality of life (QOL) or need for invasive follow-up in this group of women. METHODS From November 1999 to October 2002, 184 women at intermediate risk of ovarian carcinoma were enrolled in a prospective study. Participants were screened with twice yearly transvaginal ultrasound and CA 125 assessments. Impact on QOL was measured using the Mental Component Summary (MCS) score of the Medical Outcomes Studies Short Form-36. Need for invasive follow-up was determined by questionnaire and medical record review. RESULTS In the current study, 135 participants underwent , 1 follow-up assessment. During a mean of 19.8 months of follow-up, 12.9% of ultrasounds and 3.8% of CA 125 assessments were abnormal. The authors reported that 38.5% of participants had , 1 abnormal ovarian screen that required a short interval follow-up. Because of either abnormal bleeding or ultrasound abnormalities, 24% of participants underwent , 1 endometrial sampling. Controlling for a history of breast carcinoma and menopausal status, abnormal ovarian screening results were associated with a decrease in MCS score (P = 0.034), whereas the need for endometrial sampling was not (P = 0.87). CONCLUSIONS Ovarian carcinoma screening in women at intermediate risk was associated with a substantial rate of abnormal screen results, endometrial sampling, and in women with abnormal ovarian screening findings, a decrease in MCS scores. These findings may have important implications for women considering ovarian carcinoma screening and for the design of future ovarian carcinoma screening trials.

A clinical and genetic study of 56 Saudi Wilson disease patients: identification of Saudi-specific mutations

EUROPEAN JOURNAL OF NEUROLOGY, Issue 2 2004
M. Al Jumah
Wilson disease (WD) is a hereditary disorder, with recessive transmission and genetic heterogeneity. Several mutations of ATP7B, the gene underlying WD, were reported in many ethnic groups. In this study, mutation screening in ATP7B of 56 Saudi Arabian WD patients was undertaken. The clinical data of all patients were recorded. The entire ATP7B coding sequence, including intron,exon boundaries were screened for mutation by the polymerase chain reaction (PCR)-based mutation detection technique and DNA sequencing. Thirty-nine patients were symptomatic at presentation and 17 subjects were pre-symptomatic siblings of affected patients. Fourteen patients had neurological, 11 patients had mixed (hepatic and neurological), and 14 patients had hepatic presentations. Family history suggestive of WD was present in 72% of cases and 68% had consanguineous parents. Genetic analysis showed disease-causing mutations in three exons (exons 8, 19 and 21) of the ATP7B gene in 28 patients (50%). Mutations in exons 21 (18 cases) and 19 (one case) were unique for Saudis. This large series of Saudi patients with WD has shown wide variability in the genomic substrate of WD. There is no correlation between genotype and clinical presentation. [source]


An unusual association of pemphigus vulgaris with hyperprolactinemia

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002
MNAMS, Sujay Khandpur MD
A 21-year-old unmarried woman presented with oral ulcerations and generalized, itchy, fluid-filled, skin lesions of 10 days' duration. The lesions ruptured spontaneously, resulting in extensive denuded areas covered by crusts. One month prior to this, she experienced pain and enlargement of both breasts with galactorrhea. Her menstrual cycles were normal initially, but later she developed menstrual irregularities. No past history suggestive of any other systemic or skin disease, including atopy or drug allergies, could be obtained. Her family history was not contributory. Dermatologic examination revealed multiple, flaccid bullae and extensive denuded areas of skin covered with crusts over the scalp, face, trunk, and upper and lower limbs (Fig. 1). Bulla spread sign and Nikolsky's sign were positive. The oral mucosa, including the lips, buccal surface, tongue, and palate, showed multiple erosions covered with necrotic slough. The rest of the mucocutaneous and systemic examination was within normal limits. Figure 1. Extensive erosions and flaccid bullae over the trunk with breast enlargement The patient's diagnostic work-up revealed: hemoglobin, 11.2 g%; total leukocyte count, 7400/mm3; differential leukocyte count, P62L34E2M2; erythrocyte sedimentation rate, 34 mm/h. A peripheral blood smear examination, urinalysis, blood sugar, and renal and liver function tests were normal. Venereal Disease Research Laboratory (VDRL) test and enzyme-linked immunoabsorbent assay (ELISA) for human immunodeficiency virus (HIV) were nonreactive. Antinuclear antibody, lupus erythematosus (LE) cell, rheumatoid factor, and anti-dsDNA levels were normal. Serum protein electrophoresis demonstrated increased levels of immunoglobulin G (IgG) antibody. The serum prolactin level was significantly raised to 139.49 ng/mL (normal, 3.6,18.9 ng/mL). The sex hormone levels, however, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone, were within normal limits. The thyroid hormone profile was also unaltered. Chest X-ray was normal. Ultrasound of the abdomen and pelvis revealed no visceral abnormality and computerized tomography (CT) scan of the pituitary sella showed no adenoma. Mammography was negative for breast malignancy. A Tzanck smear prepared from the base of the erosion showed multiple acantholytic cells and lymphocytes. Histologic examination from an intact vesicle was suggestive of pemphigus vulgaris (PV), showing a suprabasal cleft with acantholytic cells and the basal layer demonstrating a "row of tombstones" appearance (Fig. 2). Direct immunofluorescence (DIF) revealed the intercellular deposition of IgG and C3 throughout the epidermis in a "fishnet pattern." Indirect immunofluorescence (IIF) test performed on rat esophagus for circulating IgG antibody was positive in a titer of 1 : 120. Figure 2. Photomicrograph showing suprabasal cleft with "row of tombstones" appearance, suggestive of pemphigus vulgaris (hematoxylin and eosin, × 40) Based on the clinical and immunohistological features, a diagnosis of PV with idiopathic hyperprolactinemia was made. The patient was treated with bromocriptine mesylate (Tablet Proctinal, Glaxo Wellcome Ltd, India) at a dose of 2.5 mg twice a day. After 2 months of therapy, significant improvement in the skin lesions was observed. The existing lesions re-epithelialized with a drastic reduction in the number and distribution of new vesicles. However, no change in the mucosal erosions was noticed. IIF test demonstrated a lower antibody titer (1 : 40). The breast complaints also improved with a reduction in serum prolactin level to 6.5 ng/mL. The patient refused further treatment as she experienced nausea and dizziness with bromocriptine. After 2 weeks, the disease relapsed with the appearance of new vesicles over the forearms, abdomen, back, and thighs. She again complained of breast tenderness and galactorrhea, and the serum prolactin level was 95 ng/mL. The IgG titer increased to 1 : 120. Hence, treatment with oral prednisolone (2 mg/kg/day) and bromocriptine (2.5 mg twice a day) with an antiemetic was initiated. After 6 weeks, the skin lesions had cleared completely, the breast symptoms had improved, menses had become regular, and the prolactin level had decreased to 4 ng/mL. IIF test was negative for circulating antibody. Steroids were tapered off and maintenance therapy with bromocriptine at a dose of 2.5 mg/day was continued. [source]

To cite this article: Agondi RC, Barros MT, Rizzo LV, Kalil J, Giavina-Bianchi P. Allergic asthma in patients with common variable immunodeficiency. Allergy 2010; 65: 510,515. Abstract Background:, Many patients with common variable immunodeficiency (CVID) have a clinical history suggestive of allergic respiratory disease. However, in such individuals, the prevalence of asthma and the role of atopy have not been well established. The objective of this study was to evaluate pulmonary function and identify asthma in patients with CVID. We also investigated the role of IgE as a trigger of asthma in these patients. Methods:, Sixty-two patients diagnosed with CVID underwent spirometry, as well as skin prick testing and in vitro determination of serum-specific IgE levels for aeroallergens, together with bronchial provocation with histamine and allergen. Results:, The most common alteration identified through spirometry was obstructive lung disease, which was observed in 29 (47.5%) of the 62 patients evaluated. Eighteen (29.0%) of the 62 patients had a clinical history suggestive of allergic asthma. By the end of the study, asthma had been diagnosed in nine (14.5%) patients and atopy had been identified in six (9.7%). In addition, allergic asthma had been diagnosed in four patients (6.5% of the sample as a whole; 22.2% of the 18 patients with a clinical history suggestive of the diagnosis). Conclusion:, In this study, CVID patients testing negative for specific IgE antibodies and suspected of having allergic asthma presented a positive response to bronchial provocation tests with allergens. To our knowledge, this is the first such study. When CVID patients with a history suggestive of allergic asthma test negative on traditional tests, additional tests designed to identify allergic asthma might be conducted. [source]


Lower prevalence of reported asthma in adolescents with symptoms of rhinitis that received neonatal BCG

ALLERGY, Issue 8 2004
S. S. da Cunha
Background:, BCG is a vaccine used against tuberculosis and leprosy and is an immunostimulant that primes TH1 lymphocytes to produce cytokines that antagonize atopy both in animal models and in man. Considering that atopy is the main risk factor for asthma, one can hypothesize that vaccination inducing TH1 responses, such as BCG, can be protective against asthma. Methods:, Objective:,To estimate the association between neonatal BCG vaccination and prevalence of asthma among adolescents. Study design:,Cross-sectional study with schoolchildren aged 12,16 years. The presence of a scar compatible with BCG was used as a surrogate of neonatal vaccination. A self administered structured questionnaire was prepared based on that used by the International Study of Asthma and Allergies in Childhood. The prevalence of asthma was categorized according to the report of lifetime wheeze, lifetime asthma, lifetime asthma among those referring allergy and among those referring allergy and sneezing. Results:, Neonatal BCG vaccination was not associated with the overall prevalence of reported wheezing or asthma. However, in the subgroup reporting current allergy and sneezing, neonatal BCG was associated with a 37% reduction of prevalence of lifetime asthma. Conclusions:, In the population we surveyed, neonatal BCG scar was associated with a reduction in the risk of asthma only in individuals with a past history suggestive of allergic rhinitis.

PEDIATRICS INTERNATIONAL, Issue 6 2005
Fabio Midulla
AbstractBackground:,The aim was to investigate the role of physical and radiological findings before bronchoscopy in the diagnosis of foreign body aspiration (FBA). Methods:,We retrospectively reviewed the clinical records for 82 patients (mean age 26.4 ± 21.4 months, range 9 months to 13.5 years; 49 males) with a history suggestive of foreign body aspiration. Results:,The presence of a foreign body in the airways was confirmed in 70 children (85.4%) (mean age 25 ± 14.1 months, 45 boys). Of the 70 children, 63 patients (90%) were under 3 years of age, with a peak incidence during the second year. Of the 70 foreign bodies retrieved, 46 (60%) were vegetable and 35 (76%) of these were nuts. In 42% of the patients the foreign body was located in the right bronchial tree. The most frequent physical findings observed in our patients were persistent cough (75%), localized decreased breath sound (62.8%) and localized wheezing (30%). The clinical triad (concomitant cough, localized wheezing and decreased breath sound) was present in 11 patients (15.7%). All clinical findings had a high positive predictive value with poor sensitivity. In 11 patients (20%) chest X-rays were normal. Five foreign bodies (9.1%) were radiopaque. The most frequent radiological findings observed were localized air trapping (43.6%), followed by atelectasis (40%). The diagnostic sensitivity was 80% and the specificity 33% for the presence of a single positive radiological finding. Conclusions:,Our study confirmed that clinical symptoms and radiological findings before bronchoscopy have a low diagnostic value in children with a history of FBA. [source]


Kiwi fruit is a significant allergen and is associated with differing patterns of reactivity in children and adults

CLINICAL & EXPERIMENTAL ALLERGY, Issue 7 2004
J. S. A. Lucas
Summary Background Allergy to kiwi fruit appears increasingly common, but few studies have evaluated its clinical characteristics, or evaluated methods of investigating the allergy. Objective To characterize the clinical characteristics of kiwi fruit allergy and to study the role of double-blind placebo-controlled food challenge (DBPCFC), skin tests and specific IgE in the diagnosis of this food allergy. Methods Two-hundred and seventy-three subjects with a history suggestive of allergy to kiwi completed a questionnaire. Forty-five were investigated by DBPCFC, prick-to-prick skin testing with fresh kiwi pulp, and specific IgE measurement. Nineteen subjects were also skin tested using a commercially available solution. Results The most frequently reported symptoms were localized to the oral mucosa (65%), but severe symptoms (wheeze, cyanosis or collapse) were reported by 18% of subjects. Young children were significantly more likely than adults to react on their first known exposure (P<0.001), and to report severe symptoms (P=0.008). Twenty-four of 45 subjects (53%) had allergy confirmed by DBPCFC. Prick-to-prick skin test with fresh kiwi was positive in 93% of subjects who had allergy confirmed by DBPCFC, and also in 55% of subjects with a negative food challenge. The commercial extract was significantly less sensitive, but with fewer false-positive reactions. CAP sIgE was only positive in 54% of subjects who had a positive challenge. Conclusions Kiwi fruit should be considered a significant food allergen, capable of causing severe reactions, particularly in young children. DBPCFC confirmed allergy to kiwi fruit in 53% of the subjects tested, who had a previous history suggestive of kiwi allergy. Skin testing with fresh fruit has good sensitivity (93%), but poor specificity (45%) in this population. CAP sIgE and a commercially available skin test solution were both much less sensitive (54%; 75%) but had better specificity (90%; 67%). [source]
