    Full Text Available Dystrophic epidermolysis bullosa (DEB, a rare form of EB, is characterized by defects in Type VII collagen which is encoded by COL7A1 gene located on chromosome 3p21. A 12-year-old female with low intelligent quotient presented with intensely pruritic multiple violaceous papules which were coalescent at areas on both the shins. Histopathological examination showed epidermis displaying focal thinning. A subepidermal cleft was seen beneath the basement membrane zone. The dermis showed a linear array of keratinous cysts with intervening diffuse lymphohistiocytic infiltrate. Features were suggestive of pretibial DEB. Since it was associated with intense itching, the lesion was termed as pretibial DEB pruriginosa which has combined elements of exclusive pretibial lesions and intense itching. An appropriate clinical history and increased awareness of histopathological features will enable earlier diagnosis and suitable management.

    To determine the clinical features and demographic profile of the patients having papular urticaria. Individuals of all age groups and either gender either suspected of or having definite history of insect bite were included in the study. A specially-designed proforma was filled for each patient separately. The proforma included demographic features, information regarding clothing and sleeping habits, personal or family history of atopy and clinical patterns of the lesions. Computer programme SPSS 10 was used to manage and analyze the data. Out of 280 patients, 201 (71.8%) were children upto 12 years of age, 178 (63.6%) were males, 91 (32.5%) had atopy, 194 (69.3%) were non-locals, 212 (75.7%) came from urban/peri-urban areas and 173 (61.8%) presented during May-August. Lesions were present over exposed parts of the body in 36 (12.9%), arranged in groups in 152 (54.3%) and were papular urticaria in 185 (66.1%) patients. Children, adult males, non-locals and those belonging to urban/peri-urban areas are more vulnerable to papular urticaria in a particular region. Papular and urticarial lesions arranged in groups over both exposed as well as covered body parts of a single patient is the most common clinical pattern. (author)

    Papular urticaria is a chronic allergic reaction induced by insect bites, which is common in the tropics. The objective of this review was to deepen on epidemiological and immunological aspects of this disease, focused on data published in Latin American countries.We conducted a non-systematic review of the literature through electronic search on the epidemiology of papular urticaria, the entomological characteristics of the causative agents and associated immunological mechanisms.Several reports from medical centers suggest that papular urticaria is common in Latin America. Only one epidemiological survey designed to estimate prevalence of papular urticaria has been published, reporting that about a quarter of children under six years of age is affected by this condition in Bogotá. There is evidence on the causal relationship among exposure to indoor fleas, poverty and papular urticaria in Bogotá, a representative city of the Andean altitudes. Information about causal insects in tropical warmer areas is scarce, although from clinical reports Aedes aegypti and Culex quienquefasciatus appear to be the most common. Th2 cellular-mediated mechanisms are involved in its pathogenesis, which explains its delayed hypersensitivity. The role of immunoglobulin E is not clear in this disease. Insect-derived antigens directly involved in papular urticaria etiology are unknown. However, it is possible that common molecules among causal insects mediate cross-reactive reactions, such as Cte f 2 allergen, found in cat fleas, and its counterparts in mosquitoes.Papular urticaria is a frequent disease in Latin America that should be further investigated. Immunological characterization of the molecular components that cause this condition may solve questions about its pathogenesis.

    Full Text Available Lichen myxoedematosus (synonym, papular mucinosis is an uncommon, chronic, idiopathic disorder characterized by lichenoid papules, nodules and/or plaques due to dermal mucin deposition and a variable degree of fibrosis in the absence of thyroid dysfunction. Actually, lichen myxoedematosus includes two clinicopathologic subsets: a generalized papular and sclerodermoid form (also called scleromyxedema with a monoclonal gammopathy and systemic, even lethal, manifestations and a localized papular form with non-disabling course. Discrete papular mucinosis is a rare subtype of the localized form and can be associated with hepatitis C virus and human immunodeficiency virus (HIV infection. Only 12 cases unrelated to HCV or HIV infection have been described in the literature to date. Herein, we report a 64-year-old woman who presented with asymptomatic, flat, flesh-coloured papules on her neck, upper trunk and proximal extremities. A skin biopsy from a papule on her neck demonstrated dermal mucin deposition after alcian blue staining. The number of fibroblasts was increased. Laboratory studies revealed normal thyroid function tests. Serum protein electrophoresis did not show any evidence of a monoclonal gammopathy. Serology tests for HCV and HIV were negative.

    Wearable technology is an exciting new field in humans and animals. In dogs activity monitors have helped to provide objective measurement tools where pet owner observation had been the only source of information. Previous research has focused on measuring overall activity versus rest. This has been relatively useful in determining changes in activity in orthopedic disease or post-surgical cases [Malek et al., BMC Vet Res 8:185, 2012, Yashari et al., BMC Vet Res 11:146, 2015]. Assessment of pruritus via changes in activity, however, requires an assumption that increased activity is due to scratching or other pruritic behaviors. This is an inaccurate method with obvious flaws as other behaviors may also register as greater activity. The objective of this study was to validate the ability of a multidimensional high frequency sensor and advanced computer analysis system, (Vetrax®, AgLogica Holdings, Inc., Norcross, GA, USA) to specifically identify pruritic behaviors (scratching and head shaking). To establish differences between behaviors, sensor and time stamped video data were collected from 361 normal and pruritic dogs. Video annotations were made by two observers independently, while blinded to sensor data, and then evaluated for agreement. Annotations that agreed between the two were used for further analysis. The annotations specified behaviors at specific times in order to compare with sensor data. A computer algorithm was developed to interpret and differentiate between these behaviors. Test subject data was then utilized to test and score the system's ability to accurately predict behaviors. Results for prediction of head shaking behavior included sensitivity and specificity of 72.16% and 99.78% respectively. Analysis of scratching produced sensitivity and specificity of 76.85% and 99.73% respectively. These results illustrate the ability of the system to accurately report both scratching and head shaking with an overall accuracy of 99.24% and 99

    PENS is a rare neuro-cutaneous syndrome that has been recently described. It involves one or more congenital epidermal hamartomas of the papular epidermal nevus with "skyline" basal cell layer type (PENS) as well as non-specific neurological anomalies. Herein, we describe an original case in which the epidermal hamartomas are associated with autism spectrum disorder (ASD). A 6-year-old boy with a previous history of severe ASD was referred to us for asymptomatic pigmented congenital plaques on the forehead and occipital region. Clinical examination revealed a light brown verrucous mediofrontal plaque in the form of an inverted comma with a flat striated surface comprising coalescent polygonal papules, and a clinically similar round occipital plaque. Repeated biopsies revealed the presence of acanthotic epidermis covered with orthokeratotic hyperkeratosis with occasionally broadened epidermal crests and basal hyperpigmentation, pointing towards an anatomoclinical diagnosis of PENS. A diagnosis of PENS hamartoma was made on the basis of the clinical characteristics and histopathological analysis of the skin lesions. This condition is defined clinically as coalescent polygonal papules with a flat or rough surface, a round or comma-like shape and light brown coloring. Histopathological examination showed the presence of a regular palisade "skyline" arrangement of basal cell epidermal nuclei which, while apparently pathognomonic, is neither a constant feature nor essential for diagnosis. Association of a PENS hamartoma and neurological disorders allows classification of PENS as a new keratinocytic epidermal hamartoma syndrome. The early neurological signs, of varying severity, are non-specific and include psychomotor retardation, learning difficulties, dyslexia, hyperactivity, attention deficit disorder and epilepsy. There have been no reports hitherto of the presence of ASD as observed in the case we present. This new case report of PENS confirms the autonomous nature

    Pre-tibial lacerations are complex wounds affecting a primarily aged population, with poor healing and a potentially significant impact on social well-being. Management of these wounds has changed little in 20 years, despite significant advances in wound care. A retrospective observational study was undertaken to observe current wound care practice and to assess the effect of various medical factors on wound healing time on 24 elderly patients throughout their wound journey. Wound length was found to be substantively and significantly associated with wound healing time, with a reduction in instantaneous healing rate of about 30% for every increase of 1 cm in wound length. Hence, longer wounds are associated with longer wound healing times. Prescription of several categories of drugs, including those for ischaemic heart disease (IHD), hypertension, respiratory disease or asthma; and the age of the patient were not significantly associated with wound healing times, although substantive significance could be inferred in the case of prescription for IHD and asthma. Despite the small sample size, this study identified a clear association between healing and length of wound. Neither the comorbidities nor prescriptions explored showed any significant association although some seem to be more prevalent in this patient group. The study also highlighted other issues that require further exploration including the social and economic impact of these wounds. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

  16. Demodex gatoi -associated contagious pruritic dermatosis in cats - a report from six households in Finland

    2009-10-01

    Full Text Available Abstract Background Demodex gatoi is unique among demodectic mites. It possesses a distinct stubby appearance, and, instead of residing in the hair follicles, it dwells in the keratin layer of the epidermis, causing a pruritic and contagious skin disease in cats. Little is known of the occurrence of D. gatoi in Europe or control of D. gatoi infestation. Case presentation We describe D. gatoi in 10 cats, including five Cornish Rex, two Burmese, one Exotic, one Persian and one Siamese, living in six multi-cat households in different locations in Finland containing 21 cats in total. Intense pruritus was the main clinical sign. Scaling, broken hairs, alopecia and self-inflicted excoriations were also observed. Diagnosis was based on finding typical short-bodied demodectic mites in skin scrapings, skin biopsies or on tape strips. Other pruritic skin diseases, such as allergies and dermatophytoses, were ruled out. In one household, despite finding several mites on one cat, all six cats of the household remained symptomless. Amitraz used weekly at a concentration of 125-250 ppm for 2-3 months, proved successful in three households, 2% lime sulphur weekly dips applied for six weeks in one household and peroral ivermectin (1 mg every other day for 10 weeks in one household. Previous trials in four households with imidacloprid-moxidectin, selamectin or injected ivermectin given once or twice a month appeared ineffective. Conclusion D. gatoi-associated dermatitis is an emerging contagious skin disease in cats in Finland. Although pruritus is common, some cats may harbour the mites without clinical signs. In addition, due to translucency of the mites and fastidious feline grooming habits, the diagnosis may be challenging. An effective and convenient way to treat D. gatoi infestations has yet to emerge.

    Pruritus is a characteristic clinical sign of allergic skin conditions including atopic dermatitis (AD) in the dog. IL-31 is a cytokine found in the serum of some dogs with AD and can induce pruritic behaviours in laboratory beagle dogs. The objectives were to characterize an IL-31-induced pruritus model by evaluating the efficacy of prednisolone, dexamethasone and oclacitinib, and to compare the speed of anti-pruritic effects of oclacitinib against those of prednisolone and dexamethasone. Purpose-bred beagle dogs were used in all studies. Randomized, blinded, placebo-controlled studies were designed to evaluate and compare the anti-pruritic properties of prednisolone, dexamethasone and oclacitinib following a single intravenous injection of recombinant canine IL-31. Video surveillance was used to monitor and score pruritic behaviours in study animals. Prednisolone [0.5 mg/kg, per os (p.o.)] reduced IL-31-induced pruritus when given 10 h prior to observation. When the time interval between drug treatment and observation was shortened to 1 h, dexamethasone (0.2 mg/kg, intramuscular) but not prednisolone (0.25 or 0.5 mg/kg, p.o.) reduced IL-31-induced pruritus. Oclacitinib (0.4 mg/kg, p.o.) reduced pruritus when given 1, 6, 11 and 16 h prior to the observation period, and the anti-pruritic activity of oclacitinib was greater when compared to prednisolone and dexamethasone at all time points assessed. The efficacy of prednisolone, dexamethasone and oclacitinib in the IL-31-induced pruritus model gives confidence that this may be a relevant model for acute pruritus associated with allergic dermatitis including AD and can be used to evaluate novel compounds or formulations. © 2015 Zoetis Inc.

    Full Text Available A 50-year-old diabetic female presented with highly pruritic vesicles and excoriated lesions over the anterior aspect of both lower legs. The lesions were recurrent over the last two years. She received a lot of medications with partial response. Hb A1c was 10.8% (normal up to 7%. CBC showed microcytic, hypochromic anemia. Serum zinc, folate, IgE, TSH and T4 were all within normal ranges. Biopsy showed epidermal separation secondary to keratinocyte necrosis and minimal monocytic, perivascular infiltrate. Direct immunofluorescence was negative for intraepidermal and subepidremal deposition of immunoglobulin. The dermis was positive for mucin deposition stainable by both PAS and Alcian blue while it was negative for Congo red and APC immunoperoxidase staining for amyloid material. In conclusion, the case was diagnosed as bullosis diabeticorum by distinctive clinical and pathological features and after exclusion of other possible differentials. Pruritus was partially controlled by topical potent steroid and the case was resolved spontaneously after eight months.

    The nursing programme 'Coping with Itch' aims at reducing itch and at helping patients with chronic pruritic skin diseases cope with itch. The programme consists of educational and cognitive behavioural interventions. Dermatology nurses carry out the programme, which supplements standard medical treatment given by a dermatologist, in individual sessions at a nurse clinic organized by the dermatology outpatient department. To evaluate the effectiveness of the nursing programme 'Coping with Itch' in patients with chronic pruritic skin diseases. A randomized controlled study was carried out. Patients with chronic pruritic skin diseases were randomly assigned to the intervention group or the control group. The intervention group received standard care from a dermatologist and nursing care according to the programme 'Coping with Itch' for a mean of 2.9 visits. The control group received usual care from a dermatologist. Data collection took place at baseline, at 3 months (t1) and at 9 months (t2) after baseline. Most visits to the nurse clinic took place during the first 3 months of the study. Main outcome measures were the frequency and intensity of itching and scratching, itch-related coping, and skin-related and general psychosocial morbidity. Secondary outcome measures were the number of visits to the dermatologist and the use of medication and ointments. Mann-Whitney tests and analyses of covariance were used to analyse differences between the two groups. Data on 29 patients in the intervention group and 36 patients in the control group were used in the analyses. A trend to significance (P = 0.07) was shown in the difference between the two groups in the frequency of itching and scratching at t1. A significant difference (P = 0.04) was shown between the two groups in catastrophizing and helpless itch-related coping at t1. No significant differences were revealed at t2 between the groups. Patients in the intervention group visited the dermatologist significantly less

    Full Text Available Abstract Xanthomatous skin lesions and arthritis in children are not a common association. We present the case of a 3 year old girl who presented with xanthomatous lesions in the periungual region of both hands, around the nares and on her forehead, associated with significant arthritis that was clinically compatible with multicentric reticulohistiocytosis. However, pathology of the xanthomatous lesions was more suggestive of papular xanthoma, a disease that is not associated with arthritis. Based on her presentation and the negative lipid workup, she was treated for presumed multicentric reticulohistiocytosis. Multiple treatment strategies were utilized, with improvement on a combination of infliximab, methotrexate, and prednisone. We review the different diagnoses that should be considered in children with xanthomas and arthritis as well as the different pharmacologic therapies used in children with multicentric reticulohistiocytosis.

    To improve health outcomes during the treatment for pruritic skin diseases, it is important to understand which factors most influence patients' concerns about oral antihistamine drugs. To survey the nature of patients' concerns about oral antihistamine drugs and to examine the factors associated with them. Patients with pruritic skin diseases expressed their concerns regarding the use of oral antihistamine drugs. The independent effects of the patients' background characteristics on their concerns were examined by multiple logistic regression analysis. A total of 291 outpatients were completed the study. Overall, 32% of patients were worried about using oral antihistamine drugs. The most common concern was about their adverse drug events (except drowsiness) and the effects of long-term use. Overall, being concerned about antihistamine use was found to be significantly and independently associated with a younger age, severe itching, being a homemaker, and having previous personal experience of embarrassment due to drowsiness caused by taking over-the-counter drugs. Several factors are associated with altered self-reported concerns about antihistamines. Our results suggest the importance of understanding the nature of patients' fears about oral antihistamine use so that sound advice can be offered to them in a timely manner.

    Veterinarians and pet owners have limited ability to assess pruritic behaviors in dogs. This pilot study assessed the capacity of the Vetrax® triaxial accelerometer to measure these behaviors in six dogs with pruritus likely due to environmental allergens. Dogs wore the activity monitor for two weeks while consuming their usual pet food (baseline), then for eight weeks while consuming a veterinary-exclusive pet food for dogs with suspected non-food-related skin conditions (Hill’s Prescription Diet® Derm DefenseTM Canine dry food). Veterinarians and owners completed questionnaires during baseline, phase 1 (days 1–28) and phase 2 (days 29–56) without knowledge of the activity data. Continuous 3-axis accelerometer data was processed using proprietary behavior recognition algorithms and analyzed using general linear mixed models with false discovery rate-adjusted p values. Veterinarian-assessed overall clinical signs of pruritus were significantly predicted by scratching (β 0.176, p = 0.008), head shaking (β 0.197, p food, the Vetrax® sensor provided an objective assessment of clinically relevant pruritic behaviors that agreed with owner and veterinarian reports.

In most cases, the skin lesions develop in the third trimester of primigravidas. There are no systemic alterations seen in PUPPP; however, most patients report severe pruritus. A 34-year-old woman presented 1 week postpartum with typical clinical features of PUPPP. The patient showed good response to intramuscular injection of autologous whole blood with no adverse effects to the patient or her baby. Presentation of PUPPP in the postpartum period is rare. Conservative management with topical corticosteroids and oral antihistamines is commonly used to relieve pruritus. In severe cases, skin lesions and symptoms are controlled with a brief course of systemic corticosteroids. Investigation of new treatment options has been limited by patient concerns about the negative effects of medication on the fetus or breastfeeding. Intramuscular injection of autologous whole blood could be an alternative treatment option for PUPPP, especially for women who worry about the use of medications during pregnancy or breastfeeding.

    Full Text Available Abstract Background Papular urticaria is a chronic inflammatory disease caused by exposure to arthropod bites. The disease has been reported in children attending medical centers, but the causes as the risk factors associated with the disease have not been established. The objective of this study was to determine the prevalence of papular urticaria caused by flea bite and identify the risk factors in children between 1 to 6 years of age in Bogotá D.C, between March 2009 and June 2011. Methods A cross-sectional, two-stage, clustered study using random probability sampling and stratified with proportional allocation was carried out in children (1–6 years of age in educational institutions in Bogotá D.C. to determine the prevalence of the disease. Children underwent a dermatological examination by general practitioners with a previous training. Furthermore, digital photographs of skin lesions were taken for further confirmation of the diagnosis by dermatologists. A structured survey was completed by the parents or caregivers, and it was evaluated using an unconditional logistic regression to identify factors associated with the disease. Results A total of 2437 children were included in the study. The prevalence of papular urticaria caused by flea bite in this population was 20.3% (CI 95%: 18.2 to 22.5%. The major risk factors associated with the disease were the presence of fleas in households (OR 1.74, CI 95%: 1.35 to 2.25, using mattresses without springs (OR 1.73, CI 95%: 1.20 to 2.50, the use of daily public transportation to carry the children to the educational institutions (OR 1.76, CI 95%: 1.07 to 2.89, having a soil/earth floor in the main bedroom (OR 6.81, CI 95%:1.16–39.96, and having siblings with a history of atopic dermatitis (OR 1.76 CI 95%: 1.07–2.89. Conclusions A high prevalence of papular urticaria caused by flea bite was found in Bogotá D.C. The main factors associated with the disease might be modified with the

    A 54-year-old Caucasian woman with a medical history of mitral valve prolapse presented with a 5-year history asymptomatic papules. There was no family history of similar lesions. Physical examination revealed >100, 2- to 4-mm, firm, yellow, dermal papules located on the neck, antecubital and popliteal fossae, flexor surface of both forearms, and inner aspect of the thighs (Figure 1). There was no skin laxity. A 4-mm punch biopsy was obtained from the left thigh for histologic examination. Findings showed a focal increase in the concentration of elastic fibers highlighted by Verhoeff Van Gieson stain (Figure 2). There was no fragmentation, calcification, or phagocytosis of elastic fibers. There was also no evidence of actinic elastosis. A section stained with hematoxylin and eosin appeared relatively unremarkable. These findings were consistent with late-onset focal dermal elastosis.

    Full Text Available Lichen planus (LP is a common idiopathic inflammatory disorder that affects the flexor aspect of the wrists, the legs, and the oral and genital mucosa. Depending upon the site of involvement, LP can be divided into mucosal, nail, scalp, or palmoplantar types. Palmoplantar LP can pose a diagnostic problem to the clinician as it resembles common dermatoses like psoriasis, verruca, corn, calluses, lichenoid drug eruption, and papular syphilide of secondary syphilis. In this case report, we describe a 4-year-old male child who presented with highly pruritic erythematous to violaceous hyperkeratotic papules and plaques on his palms and soles. Typical LP papules were noted on the upper back. Histopathology of the papular lesion showed features of LP. Dermatoscopy of a papule from the back showed the characteristic Wickham striae. We report this rare involvement of palm and soles in a case of childhood LP.

    McCarthy, J; Kemp, D; Walton, S; Currie, B

    2004-01-01

    Human scabies, caused by skin infestation with the arthropod mite, Sarcoptes scabiei, typically results in a papular, intensely pruritic eruption involving the interdigital spaces, and flexure creases. Recent research has led to a reassessment of the morbidity attributable to this parasite in endemic communities, particularly resulting from secondary skin sepsis and postinfective complications including glomerulonephritis. This has led to studies of the benefits of community based control programmes, and to concerns regarding the emergence of drug resistance when such strategies are employed. The renewed research interest into the biology of this infection has resulted in the application of molecular tools. This has established that canine and human scabies populations are genetically distinct, a finding with major implications for the formulation of public health control policies. Further research is needed to increase understanding of drug resistance, and to identify new drug targets and potential vaccine candidates. PMID:15254301

    The superficial dorsal horn, which is the main target for nociceptive and pruritoceptive primary afferents, contains a high density of excitatory interneurons. Our understanding of their roles in somatosensory processing has been restricted by the difficulty of distinguishing functional populations among these cells. We recently defined 3 nonoverlapping populations among the excitatory neurons, based on the expression of neurotensin, neurokinin B, and gastrin-releasing peptide. Here we identify and characterise another population: neurons that express the tachykinin peptide substance P. We show with immunocytochemistry that its precursor protein (preprotachykinin A, PPTA) can be detected in ∼14% of lamina I-II neurons, and these are concentrated in the outer part of lamina II. Over 80% of the PPTA-positive cells lack the transcription factor Pax2 (which determines an inhibitory phenotype), and these account for ∼15% of the excitatory neurons in this region. They are different from the neurotensin, neurokinin B, or gastrin-releasing peptide neurons, although many of them contain somatostatin, which is widely expressed among superficial dorsal horn excitatory interneurons. We show that many of these cells respond to noxious thermal and mechanical stimuli and to intradermal injection of pruritogens. Finally, we demonstrate that these cells can also be identified in a knock-in Cre mouse line (Tac1), although our findings suggest that there is an additional population of neurons that transiently express PPTA. This population of substance P-expressing excitatory neurons is likely to play an important role in the transmission of signals that are perceived as pain and itch.

    2017-04-01

    Korean red ginseng (KRG) and ginsenosides exhibit diverse biological effects, including anti-inflammatory and anti-allergic. We aimed to investigate the therapeutic effect of KRG in a murine model of atopic dermatitis (AD) is mediated whether by diminishing the pruritus or by suppressing the inflammation. Thirty NC/Nga mice were randomly divided to 5 groups. AD-like skin lesions were induced by percutaneous challenge with 2,4,6-trinitro-1-chrolobenzene (TNCB) on the ears and backs of NC/Nga mice. KRG extract, evening primrose oil, cyclosporine, and phosphate-buffered saline were administered orally by a gastric tube. Each study group was also divided into scratching-permitted and scratching-restricted subgroups to evaluate the impact of scratching behavior on AD. The effects of KRG and the other agents were assessed by measuring the clinical severity score, ear thickness, extent of transepidermal water loss (TEWL), number of scratching movements, total systemic immunoglobulin E (IgE) and interleukin (IL)-31 levels, histologic changes of cutaneous lesions, and mRNA expression levels of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, thymic stromal lymphopoietin (TSLP), and IL-31. KRG exerts therapeutic effects against AD by inhibiting the T helper 2 (Th2) mediated inflammation as well as by diminishing the itching sensation. Moreover, restricting scratching behavior suppresses the vicious cycle of itching and scratching, thus reducing clinical and systemic inflammation in our murine model of AD. © 2017 The Korean Academy of Medical Sciences.

    Hydrolysed protein diets are used to diagnose and treat dogs with cutaneous adverse food reactions (CAFR). Little is known about what proportion of dogs hypersensitive to the native protein would react to its hydrolysed form. To determine the clinical allergenicity of hydrolysed poultry feather (RCU) and chicken liver diets (HZD) in dogs with chicken induced CAFR. In this randomized, double-blinded, crossover trial, ten dogs with chicken induced CAFR were selected after a positive oral challenge to chicken meat and a negative one to corn. Test diets were fed for 14 days separated by a 14 day wash-out period. Owners rated pruritus daily with a Visual Analog Scale (PVAS). The challenge was ended if a flare in pruritus occurred (i.e. PVAS ≥5/10). The median PVAS scores before feeding RCU and HZD were 0.9 and 1.7, respectively (Wilcoxon signed rank test, P = 0.46). Pruritus scores increased significantly after feeding HZD (Friedman's test, P dogs fed RCU, but four dogs fed HZD (40%), were withdrawn after a flare in pruritus developed (Fisher's test, P = 0.04). The maximal PVAS score was significantly higher after HZD (median: 4.7) compared to RCU (2.5) (Wilcoxon signed rank test, P = 0.01). One dog in each group was withdrawn due to diarrhoea. The hydrolysed poultry feather diet did not induce pruritus flares in dogs allergic to chicken in contrast to the hydrolysed chicken liver diet that led to pruritus flares in 40% of these dogs. © 2016 ESVD and ACVD.

    Hairless mice fed a special diet, HR-AD, develop atopic dermatitis (AD)-like skin inflammation with skin barrier defects and itch-related scratching; however, the ingredient(s) causing the dermatitis remains unclear. In this study, we examined whether deficiency of certain polyunsaturated fatty acids (PUFAs) is involved in HR-AD-induced AD. High-purity PUFAs were given to HR-AD-fed mice by dietary supplementation or gavage. Fatty acid levels in the serum and skin were determined by using gas chromatography-mass spectrometry. In serum from HR-AD-fed mice, linoleic acid (LA, 18:2n-6) and α-linolenic acid (ALA, 18:3n-3), as well as their metabolites, were markedly decreased. When mice were fed HR-AD supplemented with LA or ALA in an amount equal to that contained in a normal diet, the development of AD-like symptoms was completely prevented by supplementation with LA but not with ALA. Relatively high dose of ALA slightly alleviated skin barrier defects, but did neither itch-related scratching nor skin inflammation. On the other hand, gavage administration of LA metabolites, such as γ-linolenic acid and arachidonic acid (AA), significantly ameliorated established dermatitis without increasing LA in the serum and skin. Moreover, AA-induced amelioration of dermatitis was not affected by pharmacological blockade of 5-lipoxygenase (5-LOX) and cyclooxygenase (COX), suggesting no involvement of 5-LOX- or COX-mediated AA metabolites in the amelioration. In conclusion, our results indicate that deficiency of n-6 PUFAs is mainly responsible for AD-like symptoms by HR-AD feeding. Thus, this model could be useful for studying the pathomechanisms associated with deficiency of n-6 PUFAs in AD. © 2013 John Wiley & Sons A/S.

    Nigella sativa had been documented to possess many therapeutic functions in medicine but the least expected is sero-reversion in HIV infection which is very rare despite extensive therapy with highly active anti-retroviral therapy (HAART). This case presentation is to highlight the complete recovery and sero-reversion of adult HIV patient after treatment with Nigella sativa concoction for the period of six months. The patient presented to the herbal therapist with history of chronic fever, diarrhoea, weight loss and multiple papular pruritic lesions of 3 months duration. Examination revealed moderate weight loss, and the laboratory tests of ELISA (Genscreen) and western blot (new blot 1 & 2) confirmed sero-positivity to HIV infection with pre-treatment viral (HIV-RNA) load and CD4 count of 27,000 copies/ml and CD4 count of 250 cells/ mm(3) respectively. The patient was commenced on Nigella sativa concoction 10 mls twice daily for 6 months.. He was contacted daily to monitor side-effects and drug efficacy. Fever, diarrhoea and multiple pruritic lesions disappeared on 5th, 7th and 20th day respectively on Nigella sativa therapy. The CD4 count decreased to 160 cells/ mm3 despite significant reduction in viral load (≤1000 copies/ml) on 30th day on N. sativa. Repeated EIA and Western blot tests on 187th day on Nigella sativa therapy was sero-negative. The post therapy CD4 count was 650 cells/ mm(3) with undetectable viral (HIV-RNA) load. Several repeats of the HIV tests remained sero-negative, aviraemia and normal CD4 count since 24 months without herbal therapy. This case report reflects the fact that there are possible therapeutic agents in Nigella sativa that may effectively control HIV infection.

  16. Dermatitis Herpetiformis and Vitiligo

    Directory of Open Access Journals (Sweden)

    Ozlem Karabudak

    2007-11-01

    Full Text Available Dermatitis herpetiformis (DH is a rare immunobullous disorder of the skin that is associated with gluten hypersensitivity. Subepidermal IgA-type antibody deposition against tissue transglutaminase leads to dense neutrophilic microabscess and eventually into vesicles in dermal papillae, which may occasionally merge into bullae. Being a subepidermal vesiculobullous disorder, DH is frequently associated with postinflammatory pigmentary changes, particularly hypopigmentation. However, the association of DH with true vitiligo is extremely rare. Here, we report a 21-year-old male with vitiligo and comorbid DH, and review the literature. This new case had severely pruritic, papular and papulovesicular lesions that were localized symmetrically and partly confined to the pre-existing vitiliginous areas. The skin biopsy specimen taken from an erythematous papule on the elbow showed characteristic findings of DH and vitiligo. Direct immunofluorescence microscopy of the perilesional skin revealed granular IgA deposition of dermal papillae. There are only 10 reports in the literature of DH and vitiligo comorbidity.

    Full Text Available Background and Aims: Skin and mucocutaneous disorders are common in HIV infection and may be the earliest manifestation of the disease. The spectrum of these disorders is wide and may vary in different regions due to varying prevalence of various microbial agents. Therefore, we studied the seroprevalence of HIV infection in patients presenting with skin and mucocutaneous disorders and clinical and regional epidemiological profile of seropositive patients. Methods: Eleven hundred and seventy patients having any type of skin or mucocutaneous disorders were screened for HIV infection (NACO guidelines after recording their clinical and epidemiological profile. Results: Of the 1170 patients screened, 38 (3.24% were found to be positive for HIV 1 and none for HIV 2 antibodies. Seropositive patients belonged to the age group of 9 to 48 years, with a male:female ratio of 0.9:1. Heterosexuality was the most common mode of transmission (86.8%. A wide range of infectious and noninfectious lesions were observed and herpes zoster was the most common infectious disease (31.5% followed by mucocutaneous candidiasis (26.3%. The most common noninfectious manifestation was seborrhoeic dermatitis (18.4% followed by pruritic papular eruptions (7.9%. Conclusion: High prevalence and wide variety of skin and mucocutaneous disorders in HIV-positive patients highlight the importance of better vigilance and early suspicion of HIV infection in such patients.

    The diagnostic approach to eyelid eczema is often a great problem in daily practice. A 16-year old girl developed recurrent severe pruritic edema of the eyelids, followed by redness and scaling. Various cosmetics particularly an eyeliner were considered as possible causes. Patch testing was performed with the standard series, some supplemental series and all ingredients of the eyeliner. The eyeliner produced a papular reaction after 2 days of open application, confirming a high degree of contact sensitization. The patient reacted with a 3+ reaction to the ingredients shellac (20% in ethanol) and 1,3-butylene glycol (2% in water). All remaining materials failed to produce a reaction. Careful allergologic investigations are necessary in cases of edema and/or eczema of the eyelids; the cosmetics used by the patients are of utmost importance. The causative allergen may not be present in the usual patch test series and can only be identified by testing all ingredients. Shellac is now widely used in cosmetics and is increasingly identified as a contact allergen in eye make up.

    Full Text Available Introduction. pityriasis lichenoides chronica (PLC, which is a benign eruption with lymphocytic infiltrates of the skin, presents as a persistent, erythematous, papular eruption with scale. Patients may have guttate, hypopigmented macules with scale in addition to papules. It is related histopathologically to pityriasis lichenoides et varioliformis acuta (PLEVA, which presents as a recurrent papulonecrotic eruption. The PLC is a cutaneous disease of unknown etiology that most commonly affects children and young adults. The highly variable presentation of this condition often poses a diagnostic challenge. Objective. Presentation of two adults with PLC probably induced by infectious agents. Case reports. A woman presented with scaly, pruritic, erythematous-to-brown flattened papules, which varied in size from 3 mm to 1 cm, on the trunk and extremities, being first diagnosed as guttate psoriasis. A man sought medical advice for a disseminated eruption on the trunk and extremities, observed for 2 months before the consultation. He was in a good medical state, with no comorbidities and no medication. He complained of discrete pruritus and urethral discharge for many days. Conclusions. Pityriasis lichenoides may have arisen secondarily to these infections or there were two simultaneous diseases. Further studies must elucidate the role of infectious agents in this pathology.

    Eruptive pseudoangiomatosis was first described in children in the form of an acute non-pruritic macular or papular rash that fades on application of a glass test and resolves within several days. Viral aetiology is suspected but has never been demonstrated to date. We discuss seven cases of infants presenting this disease: 5 boys and 2 girls aged 8 days to 16 months. The rash presented typical clinical features in all cases and affected the face and limbs in 6 of the 7 subjects. In one child, involvement of the face and back was observed with sparing of the limbs. The rash occurred after an episode of rhinolaryngeal infection in 3 cases and after gastrointestinal infection in 1 case. Spontaneous resolution was seen within 3 to 10 days in 6 patients although a longer course lasting over 9 months was observed in one infant. In another patient, the rash appeared after surgery for mesoblastic nephroma. In one child, a similar rash was seen in both parents. Screening for infectious agents was negative for the two children from whom samples were obtained. This series of paediatric cases of eruptive pseudoangiomatosis is characterised by the very young age of one of the children, coexistence of the condition with a renal tumour in another child, the familial nature of the rash in a third child and unusually long disease duration in the final child. However, this series did not allow identification of the causative infectious agent or agents. Probably, as with other syndromes such as Giannotti-Crosti syndrome or "gloves and socks" syndrome, eruptive pseudoangiomatosis forms a clinical picture common to a non-specific viral infection.

    Full Text Available Background: Cutaneous disorders during HIV infection are numerous and skin is often the first and only organ affected during most of the course of HIV disease. Some Cutaneous disorders reflect the progression of HIV disease; though the relation is still controversial. Aims : The objective of this study, conducted at a tertiary care centre in Bastar, Jagdalpur, is to estimate the status of cutaneous manifestation in HIV-infected patients and its relationship with CD4 cell counts. Methods: We enrolled 137 HIV positive subjects. Demographic information such as age, gender, weight, height, socioeconomic status, and educational status were recorded. Laboratory parameter (CD4 counts and treatment regimen were noted. Patients were examined for skin disorders by a dermatologist. Data were analyzed using chi-square test for categorical variables. Results: Majority of the patients were from rural area (65.69% and belonged to a low socioeconomic and educational status. 30.65% of the patients were housewives, 23.35% drivers, and 16.78% labourers. Predominant mode of transmission was heterosexual contact (94.16%. Most common HIV-related dermatological manifestations were seborrheic dermatitis (74.16%, xerosis (52.5%, generalized skin hyperpigmentation 56 (46.67%, onychomycosis 53 (44.16%, pruritic papular eruption 27 (22.5%, oral candidiasis 21 (17.5%, photo dermatitis 21 (17.5%, and scabies 4 (3.33%. Significant correlation with low CD4+ cell counts was found for oral candidiasis (P < 0.0001 and Kaposi′s sarcoma ( P = 0.03, while other disorders such as seborrheic dermatitis ( P = 0.22, xerosis ( P = 0.25, and onychomycosis (P = 0.08 were not statistically significant. Conclusion : This study showed high prevalence of dermatological manifestations in HIV-infected subjects, and they occur more frequently with progression of HIV and decline in immune functions. Therefore, early diagnosis and management of skin disorders can improve the quality of life of

    Polymorphic light eruption (PLE) is a common idiopathic photodermatosis that typically presents with pruritic papular or papulovesicular lesions on sun-exposed skin between spring and autumn. In many subjects PLE is mild, and can usually be prevented by the use of broad-spectrum topical sunscreens and a gradual increase in sunlight exposure. However, in some individuals, sunlight exposure results in florid PLE and they often benefit from prophylactic desensitization treatment using phototherapy in early spring, an artificial method that induces a "hardening" phenomenon. To describe and evaluate the efficacy of a short desensitization protocol, based on a one-month-treatment, administered twice a week with narrow band UVB in subjects with severe polymorphic light eruption (PLE). A retrospective, open planned and non-randomized study to assess the efficacy of UVB phototherapy in prevention of polymorphic light eruption. Fifteen subjects diagnosed with severe PLE were treated with the standard protocol in our Photobiology Unit between 2014 and 2015. The effect of hardening was sustained during follow up in 87.5% of desensitization treatments. A statistically significant association (pPLE and the response to treatment was found. The effect of hardening was maintained in the vast majority of subjects, obtaining a good benefit with no PLE episodes during all the summer. We demonstrate that our standard protocol is effective, and produces a successful outcome for the majority of PLE subjects. Our protocol is shorter than those currently applied, being favourable both for the patient and the physician. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    This study aims to look at the pattern and incidence of skin diseases seen in Dermatology/Venereology clinic at the University of Benin Teaching Hospital, Benin City, Edo State, South-South Zone, Nigeria and compare it with other zones of Nigeria. This was a prospective study on pattern and incidence of skin diseases in new patients presenting at the Dermatology/ Venereology outpatient clinic of the University of Benin Teaching Hospital, Benin City, Edo State, South-South, Nigeria, from September 2006 to August 2007. All patients were seen by the researchers. Diagnosis were made clinically and sometimes with the support of histopathology. A total number of 4786 patients were seen during the study period and these comprised 2647 HIV/AIDS patients and 2112 pure Dermatological patients. Out of 4786 patients, 755 (15.8%) were new patients. The new patients comprised 96 (12.7%) children patients (< 15 years) and 659 (83.7%) adult patients (>15years). The ages of the patients ranged from 2 weeks to 80 years and more than two-third were < 40 years. There were 354 males (46.9%) and 401 females (53.1%). This represents female: male ratio of 1.1: 1. Eczematous dermatitis accounted for 20.9% of the skin diseases and was the most common of the skin diseases observed. This is consistent with observation from other zones in Nigeria. Other skin diseases observed in order of frequencies include: Papulosqamous disorder (9.0%), Infectious skin diseases like fungal, viral, bacterial and parasitic infestation, at 7.9%, 7.7%, 2.3% and 2.1% respectively. Pigmentary disorders (5.0%), hair disorders (4.2%) and Benign neoplastic skin disease (6.5%). All the patients that had neurofibromatosis were females (1.9%). HIV-related skin diseases were observed to have increased remarkably (7.9%) with Kaposi's sarcoma, papular pruritic eruptions and drug eruptions being the commonest mode of presentation. The current pattern of skin diseases in Benin City, South-South Nigeria seems to follow a

    Mucocutaneous manifestations are one of the first clinical signs in patients infected with human immunodeficiency virus (HIV). To the best of our knowledge, there has been no previous study describing dermatologic manifestations in Mauritanians infected with HIV. The aim of the present study was to determine the profiles of mucocutaneous manifestations in relation to CD 4 T cell count in HIV-positive Mauritanian patients. A total of 86 adult patients aged > 18 years old attending the Ambulatory Treatment Center of the National Hospital of Nouakchott, Mauritania, with newly diagnosed HIV and who were not under antiretroviral treatment were included in the study in 2015. Dermatologic manifestations were documented before initiating antiretroviral treatment. Most of the included patients were in clinical stage 3 of the World Health Organization classification at initial diagnosis, with the mean CD 4 T cell count (± SD) of 514 ± 319 cells/mm 3 (range, 2-1328 cells/mm 3 ), and 19 of 86 (22.1%) patients had CD 4 T cell counts below 200 cells/mm 3 . More than half (64%) of newly diagnosed HIV-infected patients had dermatoses, including the following: pruritic papular eruption (44.2%), seborrheic dermatitis (4.7%), Kaposi's sarcoma (3.5%), extensive xerosis cutis (2.3%), drug-induced skin reactions (1.2%), and various infectious dermatoses (dermatophyte infections [16.3%], oral candidiasis [11.6%], herpes zoster [8.1%], and scabies [2.3%]). A low CD 4 T cell count (< 200 cells/mm 3 ) was significantly correlated (P < 0.05) with the presence of following dermatoses: dermatophytosis, oral candidiasis, Kaposi's sarcoma, seborrheic dermatitis, and extensive xerosis cutis. Mucocutaneous lesions occur throughout the course of HIV infection, and dermatologic findings in Mauritanian HIV-positive patients are similar to those of patients in other countries. Early detection of skin disorders in some patients may help establish the diagnosis of HIV and management of HIV

    Full Text Available History of present illness: A 30-year-old African American male presents with two days of gradually worsening vesicular pruritic rash over the left naris, left upper lip, and inferior to medial epicanthus, initially noted just on the upper lip the night before. By the next day it had spread to the nose and cheek. Patient denies any fever, pain, discharge from the rash, ear or nose, or changes in vision. He denies exposure to any new hygiene products, household cleaning products, recent outdoor activities, travel, or insect bites. Past medical history significant for a childhood varicella infection. Patient works for a moving company, and had an episode of heat exhaustion at work one week prior to onset. Denies alcohol or drug abuse. Significant findings: The unilateral distribution of vesicular lesions over the patient’s left naris, cheek, and upper lip are consistent with Herpes zoster reactivation with Hutchinson’s sign. Hutchinson’s sign is a herpes zoster vesicle present on the tip or side of the nose.1 It reflects zoster involvement of the 1st branch of the trigeminal nerve, and is concerning for herpes zoster ophthalmicus.1 Herpes zoster vesicles may present as papular lesions or macular vesicles on an erythematous base.2,3 Emergent diagnosis must be made to prevent long-term visual sequelae.4 Discussion: The history of a childhood viral exanthem, specifically a past varicella infection, helps direct the diagnosis.2 Herpes zoster ophthalmicus is an ophthalmological emergency and results from viral reactivation within the V1 branch of CN V, leading to direct ocular involvement.1 Symptoms of ocular involvement include red eye, blurry vision, eye pain or photophobia.1 If left untreated, corneal ulceration, scarring, perforation, glaucoma, cataracts, and blindness may occur.1 Fluorescein staining with slit lamp examination will show a characteristic “dendritic ulcer” within the epithelial layer of the cornea.1 Treatment is generally

    2017-01-01

    Full Text Available Osteomyelitis following arthroscopically assisted anterior cruciate ligament (ACL reconstruction has rarely been reported in the literature. We report a case of a 20-year-old female who had delayed tibial osteomyelitis and a pretibial cyst with culture-positive, oxacillin sensitive Staphylococcus epidermidis 15 months after an ACL reconstruction with hamstring autograft. Soft tissue fixation within the tibial tunnel was with a poly-L-D-lactic acid (PLDLA bioabsorbable interference screw. The patient underwent surgical treatment with curettage, debridement, hardware removal, and bone grafting of the tibial tunnel followed by a course of intravenous antibiotics. Arthroscopic evaluation demonstrated an intact ACL graft without any evidence of intra-articular infection. The patient returned to collegiate athletics without any complications. While the most common biologic complications include pretibial cysts, granuloma formation, tunnel widening, and inflammatory reactions, infection is exceedingly rare. Late infection and osteomyelitis are also rare but can occur and should be considered in the differential diagnosis.

    Full Text Available Pruritus is a frequent symptom in many dermatological diseases. In this review we want to focus on not only itch problems specific to women, namely, pruritic vulvodermatoses, but also the specific pruritic dermatoses of pregnancy. The specific characteristics of the vulva and the hormonal changes during the different age periods make these dermatoses very particular. It seems that vulvar diseases are still underdiagnosed and undertreated. Pruritic vulvar diseases have a huge impact on quality of life. The most common pruritic diseases will be discussed, such as atopic and contact dermatitis, psoriasis, lichen sclerosis, lichen planus, and infectious vulvaginitis. We focus on the diagnostic issue of these diseases and will consider the general principles of therapy.

    Imatinib mesylate is a tyrosine kinase inhibitor used widely as the first-line treatment for chronic myeloid leukaemia (CML). The side-effect profile of this drug includes fluid retention, muscle cramps, diarrhoea, myelosuppression and skin rashes. Of these, rashes of the type maculo-papular eruptions and oedema developed most commonly. The cutaneous adverse reactions other than maculo-papular eruptions are rare with imatinib. Severe and life-threatening cutaneous reactions can occur in 5% cases. Here, the author reports a case of newly diagnosed CML that developed Steven-Johnsons syndrome due to imatinib therapy. Patient responded and discharged successfully on withdrawal of the culminating drug.

    We report the case of a 10-year-old boy with a full thickness chemical burn on his right pretibial area due to phytophotodermatitis (PPD) following contact with giant hogweed (Heracleum mantegazzianum). Although cutaneous burns due to plants are a well-established cause of chemical burn, previous reports described partial thickness burns that healed with conservative measures. This patient presented to our unit two weeks after the initial injury with an established full thickness burn. Debridement and split thickness skin grafting was required.

    LENUS (Irish Health Repository)

    Cunningham, Laurence Patrick

    2013-01-01

    We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma. Biopsy results revealed metastatic transitional cell carcinoma of the tibia. Intramedullary nailing was performed which relieved pain on weightbearing. The patient declined radiotherapy and was started on a palliative care regimen. This case illustrates the importance of histological diagnosis in the treatment of diaphyseal lesions.

  12. Case report 480: Periosteal amyloid tumor

    1988-01-01

    In summary, a 66-year-old woman presented with an asymptomatic left pretibial tumor of 7 years duration. Serial radiographs over this period demonstrated a slowly enlarging periosteal tumor with focal and increasing calcifications/ossifications. No involvement of the underlying medullary bone, as demonstrated by computed tomography was noted. Following the diagnosis by biopsy of an amyloid tumor, serum and urine electrophoreses, complete blood count, SMAC panel, erythrocyte sedimentation rate, and serum rheumatoid factor level were found to be within reference ranges. A needle biopsy of the abdominal wall failed to reveal amyloid in the fat by Congo-red staining. (orig.)

  13. Concomitant Graves' disease and Hashimoto's thyroiditis, presenting as primary hypothyroidism.

    LENUS (Irish Health Repository)

    Cronin, C C

    2012-02-03

    Hypothyroidism in patients with Graves\\' disease is usually the result of ablative treatment. We describe a 58 year old man with Graves\\' ophthalmopathy and pre-tibial myxoedema, who presented with spontaneous primary hypothyroidism. Circulating TSH receptor antibody activity was increased, while thyroid microsomal antibody was detectable in titres greater than one in one hundred thousand. It is likely that the TSH receptor antibody of Graves\\' disease was ineffective in stimulating hyperthyroidism because of concomitant thyroid destruction due to Hashimoto\\'s disease. Alternatively, primary hypothyroidism could have resulted from the effects of a circulating TSH receptor blocking antibody.

    Full Text Available Lichen myxoedematosus (LM, a form of primary cutaneous mucinosis, may present either as localized less severe form called papular mucinosis or diffuse more severe form called scleromyxoedema. The diffuse form is almost always associated with monoclonal gammopathy, whereas localized form is not. We report an atypical case of localized form of LM associated with multiple myeloma in a 66-year-old male, who presented with asymptomatic waxy papular eruption on extremities, which on histopathological examination confirmed the diagnosis of cutaneous mucinosis. After initially being put on steroids and hydroxychloroquine with minimal improvement, patient subsequently presented with encephalopathy and on evaluation revealed hypernatremia, hypercalcemia, hypergammaglobulinemia, reversal of albumin-globulin (A/G ratio, azotemia, and lytic lesions in skull X-ray. Bone marrow aspiration and biopsy confirmed multiple myeloma. Patient was successfully treated with standard treatment regimen for multiple myeloma with bortezumib and dexamethasone and his skin lesions subsided completely.

    Full Text Available BACKGROUND Paediatric dermatology is a unique subspecialty in that child is not a miniature adult. Paediatric dermatoses differ from that of the adults in clinical presentation, treatment and prognosis. Various studies from India have shown infections and infestations to be the most common paediatric dermatoses. This study was planned to determine the epidemiological pattern of common noninfectious dermatoses in our paediatric patients as no such data are available from this part of the country. A cross-sectional study was undertaken to study the prevalence of the noninfectious dermatoses in all the new paediatric patients attending the Skin Outpatient Department (OPD at Villupuram Medical College over a period of three years. MATERIALS AND METHODS A total number of 550 children in the age group ranging from newborn to 12 years with noninfectious dermatoses attending the OPD for the first time were enrolled in the study. RESULTS Physiological changes of skin was the most common dermatoses in the newborn age group, while eczema was the most common dermatoses in infants, preschool and school going children. In the infants, eczema was followed by pigmentary disorders, mongolian spots, vascular nevi, ichthyosis, epidermolysis bullosa, alopecia areata and papular urticaria in the order of prevalence. Among preschool going children, eczema was followed by papular urticaria, papulosquamous disorders, pigmentary disorders, hair disorders, nevi, drug reactions, keratinisation disorders, urticaria, etc. In the school going age group, eczema was followed by papulosquamous disorders, pigmentary disorders, papular urticaria, nutritional disorders, ichthyosis, nevi, miliaria, drug reaction, hair disorders, photodermatoses, urticaria, collagen vascular disease and vascular nevi in the order of prevalence. CONCLUSION Eczema, papulosquamous disorders, papular urticaria, pigmentary disorders seem to be the most common noninfectious dermatoses in children. However

    1994-11-01

    In a review of 250 cases of lymphedema of the lower extremity, 9 patients were noted to share unique similarities in their history and physical findings. Although these patients had mild swelling in their pretibial areas and were all referred with a diagnosis of lymphedema of the legs, their findings differed significantly from the usual patient with either congenital or acquired lymphedema. Notably, the lower extremity swelling was always bilateral and symmetrical in nature and never involved the feet. Skin changes characteristic of lymphedema were not found, and consistent fat pads were present anterior to the lateral malleoli in each patient. These findings are representative of a clinical entity known as lipedema, which is distinct from lymphedema and for which treatment may be different.

    2013-01-01

    Pruritus and psyche are intricately and reciprocally related, with psychophysiological evidence and psychopathological explanations helping us to understand their complex association. Their interaction may be conceptualized and classified into 3 groups: pruritic diseases with psychiatric sequelae, pruritic diseases aggravated by psychosocial factors, and psychiatric disorders causing pruritus. Management of chronic pruritus is directed at treating the underlying causes and adopting a multidisciplinary approach to address the dermatologic, somatosensory, cognitive, and emotional aspects. Pharmcotherapeutic agents that are useful for chronic pruritus with comorbid depression and/or anxiety comprise selective serotonin reuptake inhibitors, mirtazapine, tricyclic antidepressants (amitriptyline and doxepin), and anticonvulsants (gabapentin, pregabalin); the role of neurokinin receptor-1 antagonists awaits verification. Antipsychotics are required for treating itch and formication associated with schizophrenia and delusion of parasitosis (including Morgellons disease). Copyright © 2013 Elsevier Inc.

    Directory of Open Access Journals (Sweden)

    Shun Kitaba

    2009-01-01

    Full Text Available Besides histamine, substance P (SP has been demonstrated to play a crucial role in pruritic skin diseases. Although antihistamines are frequently used for pruritic skin diseases, little is known concerning the effect on an SP-induced event such as mast cell degranulation and the upregulation of adhesion molecules or the nitric oxide (NO synthesis in endothelial cells. Our aim was to study the effect of bepotastine besilate on SP-induced degranulation of rat basophillic leukemia (RBL-2H3 cells and expression of adhesion molecules and NO synthesis in human dermal microvascular endothelial cells (HMVECs. Bepotastine besilate significantly inhibited SP-induced degranulation of RBL-2H3 cells and NO synthesis in HMVECs. Bepotastine besilate significantly inhibited expression of adhesion molecules in HMVESs, while it failed to suppress SP-induced upregulation of the adhesion molecules in HMVECs. Therefore, bepotastine besilate is assumed to act favorably on SP-induced basophil degranulation and NO synthesis in HMVECs.

    Wahl, R U; Wurpts, G; Merk, H F

    2014-05-01

    Aluminium salts are common adjuvants in all established inactivated vaccines. They are necessary to activate the humoral immune system. In the 1990s a Swedish study on an acellular vaccination against pertussis was started. Until 2013, 745 of 760,000 children with pruritic subcutaneous nodules were identified. In 77 % of these children a contact allergy to aluminium could be proven. Contact allergy to aluminium induced by vaccines causes pruritic subcutaneous nodules at the vaccination site. During infections of the upper respiratory tract the pruritus often escalates with inflammatory, erythematous and urticarial plaques. The use of solutions containing aluminium salts for specific immunotherapy is contraindicated in the case of contact allergy to aluminium. Intramuscular injections of inactivated vaccines can be employed to avoid granuloma formation.

Polish patients with CLM are usually tourists visiting tropical and subtropical countries. The first symptoms do not always appear as creeping eruptions, which complicates the diagnosis. Objective. To present the case of a man with CLM after returning from Thailand to Poland and associated diagnostic difficulties. Case report. We present a case of a 28-year-old man who returned to Poland from Thailand. The first symptoms appeared as disseminated pruritic papules. No improvement after treatment with corticosteroids and antihistamines was observed. The diagnosis was established after the appearance of serpentine erythemas and improvement after albendazole therapy. Conclusions. In the case of returnees from exotic countries suffering from raised, pruritic rashes, and no improvement after treatment with corticosteroids and antihistamines, parasitic etiology should be considered.

    Erythema multiforme (EM) and Stevens-Johnson syndrome (SJS) are thought to be hypersensitivity syndromes with various causes, and radiotherapy might be one of the causes of these syndromes. We herein report two cases of EM/SJS following radiotherapy. The first case was a 63-year-old woman with breast cancer. At the end of postoperative radiotherapy with 60 Gy, severe pruritic erythema appeared in the irradiated area and spread over the whole body. She was diagnosed with EM by a skin biopsy. The second case was a 77-year-old woman with uterine cervical cancer who underwent postoperative radiotherapy. At a dose of 30.6 Gy, pruritic redness appeared in the irradiated area and the precordial region, and it became widespread rapidly with polymorphic transformation. Although without any histological confirmation, SJS was strongly suspected because of her pruritic conjunctivitis. Because both patients were given medicines during irradiation, radiotherapy may not be the only cause of EM/SJS. However, it should be noted that radiotherapy might trigger EM/SJS. (author)

    Histamine is a potent mediator of itch in humans, yet histamine H(1) receptor antagonists have been shown to be of limited use in the treatment of certain chronic pruritic diseases. The histamine H(4) receptor is a recently described histamine receptor, expressed on hematopoietic cells, linked to the pathology of allergy and asthma. The contribution of the novel histamine H(4) receptor to histaminergic and allergic pruritus was investigated. Histamine and a selective histamine H(4) receptor agonist caused scratching responses in mice, which were almost completely attenuated in histamine H(4) receptor knockout mice or by pretreatment with the selective histamine H(4) receptor antagonist, JNJ 7777120. Pruritus induced by allergic mechanisms was also potently inhibited with histamine H(4) receptor antagonist treatment or in histamine H(4) receptor knockout mice. In all cases, the inhibitory effect of histamine H(4) receptor antagonist was greater than those observed with histamine H(1) receptor antagonists. The histamine H(4) receptor-mediated pruritus was shown to be independent of mast cells or other hematopoietic cells and may result from actions on peripheral neurons. These results demonstrate that the histamine H(4) receptor is involved in pruritic responses in mice to a greater extent than the histamine H(1) receptor. Histamine H(4) receptor antagonists may have therapeutic utility for treating chronic pruritic diseases in humans where histamine H(1) receptor antagonists are not effective.

    Oral lichen planus (OLP) is a chronic, inflammatory condition, classified by the World Health Organization as a premalignant lesion. We performed this study to evaluate the correlation between microRNA-137 (miR-137) and CD8 oral tissue expression in OLP patients. Twenty OLP patients [classified into three groups: (a) papular, reticular, or plaque; (b) atrophic; and (c) erosive] and 20 healthy controls were subjected to biopsy of the oral mucosa. To evaluate CD8 tissue expression, we performed immunohistochemical examination, followed by immunostaining and computerized quantification. The expression of miR-137 was evaluated using real-time quantitative PCR. We used SPSS software (version 15 for windows) to perform the statistical analysis. Our analysis showed an increased tissue expression of CD8 (p < 0.01) and reduced expression of miR-137 (p < 0.001) in OLP patients, compared to the control group. Moreover, there was a statistically significant difference (p = 0.001) between OLP subgroups in terms of CD8 tissue expression [highest in erosive OLP and lowest in papular/reticular/plaque OLP]. However, these subgroups showed no significant difference (p = 0.168) in terms of miR-137 expression. A negative correlation (p < 0.05) between tissue expression of miR-137 and CD8 was noted with a varying correlation coefficient in different OLP subgroups (-0.250 in erosive OLP, -0.491 in atrophic OLP and -0.616 in papular/reticular/plaque OLP). Our findings indicate reduced expression of miR-137 and a reverse correlation between tissue expression of miR-137 and CD8 in the oral mucosa of OLP patients. Future studies should investigate the therapeutic potential of miR-137 overexpression in OLP patients.

    It is difficult for rosacea patients to discern which products and ingredients will be beneficial to their skin and which products will lead to an exacerbation of the signs and symptoms of rosacea. In this paper, the authors provide a brief overview of rosacea, its pathogenesis, signs and symptoms, and the management of the two major rosacea subtypes—erythematotelangiectatic rosacea and papular pustular rosacea. Reviewed in greater detail are the common ingredients used in over-the-counter cleansers and moisturizers with discussion of how these ingredients potentially benefit or harm the skin of patients with rosacea. Clinical studies investigating the benefits of using certain over-the-counter cleansers and moisturizers in patients with erythematotelangiectatic rosacea and papular pustular rosacea with or without topical prescription therapy are also reviewed. The specific formulas used in the clinical studies include a sensitive skin synthetic detergent bar, a nonalkaline cleanser and moisturizer, polyhydroxy acid containing cleanser and moisturizer, and a ceramide-based cleanser and moisturizer formulated in a multivesicular emulsion. Based on review of available data, the authors conclude that the use of mild over-the-counter cleansers and moisturizers is beneficial for patients with erythematotelangiectatic rosacea and papular pustular rosacea. The properties of over-the-counter cleansers and moisturizers that contribute to their mildness include an acidic-neutral pH to minimize the flux in skin pH; surfactants or emulsifiers that will not strip the skin of its moisture or strip the lipids and proteins of the stratum corneum; moisturizing ingredients such as emollients, humectants, and occlusives; and formulas without potential irritants and allergens. The most consistent clinical benefits demonstrated in the reviewed studies were a subjectively perceived improvement in subjective symptoms of dryness and irritation as well as an objective improvement in

    Gianotti-Crosti syndrome is a rare disease characterized by acral papular eruption with symmetrical distribution. It is a benign and self-limited disease; the symptoms disappear after two to eight weeks, without recurrences or scars. Skin lesions are usually asymptomatic. Prodrome might occur, suggesting upper respiratory infection, or constitutional symptoms. Diagnosis is eminently clinical, and this disease is associated with viral infections. Due to its rarity and low occurrence in adolescents and adults, we report a case of Gianotti-Crosti syndrome of a teenager.

    Full Text Available Verruciform xanthoma is a rare and benign condition predominantly affecting the oral cavity, but also skin and female anogenital mucosa. It can be flat, papular-warty or crateriform-cystic. Furthermore it can simulate HPV viral lesion such as condyloma and malignant neoplasia such as verrucous squamous cell carcinoma. An accurate diagnosis is important to avoid overtreatment, considering it is a benign lesion that does not require any radical treatment. We present an extremely rare case of a 64 year-old man with a small, slighty raised, gray reddish-dotted lesion on the left portion of the ventral side of his glans.

    We report the case of an 82-year-old woman with a 6-year history of erosive palmoplantar lichen planus associated with eccrine syringofibroadenoma (ESFA). Examination revealed a well-demarcated patche writish of reticulated whitish papular lesions in skin of otherwise normal appearance at the border of erosive lichen planus plaques. These lesions had the histological appearance of ESFA. We suggest that these lesions are induced by the inflammatory remodelling associated with erosive lichen planus and propose to consider ESFA in the context of skin tissue remodelling as a new subtype of ESFA.

Forty-four OLD cases were studied and classified according to their clinical (Group C1: only papular lesions / Group C2: papular and other lesions) and histopathological features (Group HT: OLP-typical / Group HC: OLP-compatible) based in previous published criteria. Standard immunohistochemical identification of EGFR protein was performed. Comparative and descriptive statistical analyses were performed. Thirty-five cases (79.5%) showed EGFR overexpression without significant differences between clinical and histopathological groups (p<0.05). Histological groups showed significant differences in the EGFR expression pattern (p=0.016). Conlusions: All OLD samples showed high EGFR expression. The type of clinical lesion was not related with EGFR expression; however, there are differences in the EGFR expression pattern between histological groups that may be related with a different biological profile and malignant risk.

    Full Text Available Patients who present with papular rashes have a wide differential diagnosis particularly in the setting of immune compromise. A 30-year-old male diagnosed with HIV since 2009, never on antiretroviral therapy, with a nadir CD4 count of 333 cells/mm3 and a current viral load of 44,300 copies/mL, presented with a diffuse monomorphic papular eruption that began on his trunk and extremities and subsequently spread to the penis and scrotum, sparing the distal acral sites. A thorough infectious workup revealed a positive rapid plasma reagin (RPR and varicella IgM and IgG antibodies. Interestingly, the patient had been diagnosed and treated for syphilis in the past with a recent downtrending RPR drawn prior to hospitalization. Repeat RPR was elevated and a preliminary histopathology report demonstrated folliculocentric inflammation with lymphocytes, plasma cells, and polymorphonuclear leukocyte predominance supported the diagnosis of syphilis. After receiving intramuscular penicillin G benzathine, he developed intermittent fevers and new papules. Intravenous (IV acyclovir was initiated for presumed disseminated varicella given his positive varicella-zoster virus IgM and IgG. However, final pathology results revealed a large spirochete burden. The fevers and rash progression were attributed to the development of a Jarisch-Herxheimer reaction. IV acyclovir was discontinued and he completed a course of intramuscular penicillin G benzathine. He was also given a course of doxycycline for rectal chlamydia which was diagnosed during hospitalization.

    Primary localized cutaneous amyloidosis can take several clinical forms. In Asia, macular amyloidosis caused by prolonged friction from a rough nylon towel or brush is common, and macular amyloidosis and lichen amyloidosis occasionally occur together, as so-called biphasic amyloidosis. We report herein the case of an 83-year-old Japanese man with lichen amyloidosis caused by prolonged nylon towel friction. This patient presented with unique symmetrical papular lesions on the upper back and shoulders. Lesions comprised slightly shiny, brownish, fine uniform papules approximately 0.5 mm in diameter, showing a partially linear, annular or rippled arrangement. Although this case was caused by prolonged nylon towel friction, no coexisting macular lesions could be found. To the best of our knowledge, this represents the first case of lichen amyloidosis induced by nylon towel friction in the absence of the macular amyloidosis that is usually observed in such cases. We instructed the patient to stop the habit of nylon towel rubbing and prescribed a topical steroid ointment and cepharanthine. After 6 months of treatment, papular lesions became clearly flatter.

    Full Text Available Introduction: The under-five population is a unique and vulnerable component of our society that always demands special attention. Aims: Our present work aimed to study the seasonal variation, age-wise variation and distribution of lesions of common dermatoses of this age group. Materials and Methods: We clinically studied all fresh cases attending the skin OPD of our hospital for one month each from summer, rainy season and winter. Total number of patients was 879. Results: The top six skin diseases in our study were impetigo, miliaria, scabies, furunculosis, seborrheic dermatitis and papular urticaria. On statistical analysis, scabies and seborrheic dermatitis were more prevalent during winter while impetigo, furunculosis and miliaria were more during summer and rainy season. Papular urticaria was more frequent in the rainy season. Seborrheic dermatitis predominantly affected the infants while impetigo, furunculosis, miliaria and popular urticaria were commoner in older age groups. Conclusion: Distribution of lesions of common dermatoses will help diagnose difficult cases and extensive evaluation of the body parts which, by virtue of being commonly affected, are must-examine sites in under-five children.

    Full Text Available Papular elastorrhexis is a rare acquired disease, first described in 1987 by Bordas, which has been very rarely reported in the literature. It is characterized by small asymptomatic non-follicular papules, mainly distributed in the trunk. Histology of the lesions shows homogenization of collagen and fragmentation of elastic fibers in the dermis. The rarity of this disease is probably due to the subtlety and benign nature of clinical and histopathological alterations, which can be easily confused with other pathologies. The authors report the case of a patient with exuberant clinical manifestations typical of elastorrhexis papular.Elastorrexe papulosa é uma doença adquirida rara, descrita em1987 por Bordas e poucas vezes relatada na literatura. Caracteriza-se por pequenas pápulas, não foliculares, assintomáticas, distribuídas essencialmente no tronco. A histologia das lesões demonstra homogeneização do colágeno e fragmentação de fibras elásticas dérmicas. A raridade dessa entidade provavelmente se deve à sutileza e benignidade das alterações clínicas e histopatológicas, que podem facilmente ser confundidas com inúmeras outras afecções. Os autores relatam o caso de uma paciente com quadro clínico exuberante e característico de elastorrexe papulosa.

    Full Text Available Copidaster cavernicola n. sp. is described from an anchialine cave system in Cozumel, Mexico. Copidaster cavernicola differs from its congeners in having 1-8 papulae in each papular area, and numerous excavate pedicellariae on all surfaces, except between furrow spines and subambulacral spines. C. cavernicola is possibly endemic to the anchialine system which it inhabits.Se describe una especie nueva de la estrella de mar del género Copidaster encontrada en un sistema de cuevas anquihalinas del Caribe, en Cozumel, México. Copidaster cavernicola n. sp. es la primera especie cavernícola de equinodermo que es descrita, y se caracteriza por tener de 1 a 8 pápulas por cada zona papular, numerosos pedicelarios excavados presentes en toda la superficie del cuerpo excepto en el surco ubicado entre las espinas ambulacrales y subambulacrales. Se sugiere que C. cavernicola es una especie endémica propia del sistema anquihalino en el que habita.

    To estimate the incidence of maculo-papular viral exanthemas and to describe the epidemiological and clinical patterns. Observational descriptive study with a sample design. 154 practitioners from the Castilla y León Sentinel Network with a surveilled population of 23 237 people-year under 15 years old, notified in 2002 the cases of diseases by means of a standard form with the variables and inclusion and exclusion criteria. It was included the maculo-papular exanthemas associated to a presumable systemic virus disease in patients under 15 years old. It was excluded the infectious mononucleose, the chickenpox, and other non viral infections or exanthemas. 368 cases were notified which represent a incidence rate of 158.37 cases per 10 000 (95% CI, 142.31-174.42). The incidence was maximum under four years old, more than 350 per 10 000, decreasing significantly in children over this age. Erythema infectiousum presented the highest rate, followed by exanthema subitum. The exanthemas caused by measles or rubella were insignificants. Childhood exanthematous diseases of presumable viral etiology have an important incidence in primary care, although the majorities are banal and self-limited diseases. Clinical characteristics supported the suspicion diagnosis, which was consistent with the observed epidemiological description and expected presentations of each disease. Although serological analysis could diminish the uncertainly on notification and control of diseases submited to especial programs of vaccination and eradication, they would not improve substantially the diagnosis and treatment of these patients.

  17. Reduction of severity of pruritus after elective caesarean section under spinal anaesthesia with subarachnoid morphine: a randomised comparison of prophylactic granisetron and ondansetron.

    2012-02-01

    BACKGROUND: The incidence of pruritus after elective caesarean section under spinal anaesthesia with subarachnoid morphine may be 60-100%, and is a common cause of maternal dissatisfaction. Ondansetron has been shown to reduce pruritus but the effect is short-lived. The objective of this randomized double-blind trial was to evaluate the anti-pruritic efficacy of granisetron compared with ondansetron. METHODS: Eighty ASA I or II women undergoing elective caesarean section received spinal anaesthesia with 0.5% hyperbaric bupivacaine 10 mg, fentanyl 25 microg and preservative-free morphine 150 microg. After delivery of the baby and clamping of the umbilical cord, they were randomised to receive granisetron 3mg i.v. (group G) or ondansetron 8 mg i.v. (group O). RESULTS: The two groups were similar for age, gestational age, height and weight. According to visual analogue pruritus scores, patients in group G experienced less pruritus at 8h (P=0.003) and 24h (P=0.01). Fewer patients in group G (n=8) than group O (n=18) required rescue anti-pruritic medication (P=0.03). Satisfaction scores were also higher in group G than in group O (P=0.03). There was no difference in overall incidence of pruritus, nausea and vomiting, and visual analogue pain scores between the two groups. CONCLUSIONS: Administration of granisetron 3mg i.v. reduces the severity of pruritus and the use of rescue anti-pruritic medication, and improves satisfaction but does not reduce the overall incidence of pruritus in women who have received subarachnoid morphine 150 microg compared to ondansetron 8 mg i.v.

    Full Text Available Histamine is the prototypical pruritogen used in experimental itch induction. However, in most chronic pruritic diseases, itch is not predominantly mediated by histamine. Cowhage-induced itch, on the other hand, seems more characteristic of itch occurring in chronic pruritic diseases.We tested the validity of cowhage as an itch-inducing agent by contrasting it with the classical itch inducer, histamine, in healthy subjects and atopic dermatitis (AD patients. We also investigated whether there was a cumulative effect when both agents were combined.Fifteen healthy individuals and fifteen AD patients were recruited. Experimental itch induction was performed in eczema-free areas on the volar aspects of the forearm, using different itch inducers: histamine, cowhage and their combination thereof. Itch intensity was assessed continuously for 5.5 minutes after stimulus application using a computer-assisted visual analogue scale (COVAS.In both healthy and AD subjects, the mean and peak intensity of itch were higher after the application of cowhage compared to histamine, and were higher after the combined application of cowhage and histamine, compared to histamine alone (p<0.0001 in all cases. Itch intensity ratings were not significantly different between healthy and AD subjects for the same itch inducer used; however AD subjects exhibited a prolonged itch response in comparison to healthy subjects (p<0.001.Cowhage induced a more intense itch sensation compared to histamine. Cowhage was the dominant factor in itch perception when both pathways were stimulated in the same time. Cowhage-induced itch is a suitable model for the study of itch in AD and other chronic pruritic diseases, and it can serve as a new model for testing antipruritic drugs in humans.

    2013-07-01

    Full Text Available Fixed drug eruption (FDE usually appears as a solitary or a small number of pruritic, well circumscribed, erythematous macules that evolve into edematous plaques; these lesions typically resolve after discontinuation of the offending drug, leaving hyperpigmentation at the site of lesions. Fixed drug eruption has been mentioned previously as a disease model for elucidating the mechanism of how skin inflammation is caused by skin-resident T cells, a multistep process that results in eventual tissue damage. In this article we discuss the utility of dermoscopy as an additional tool which gives significant information aiding us to infer these complex processes seen in FDE and thus to confirm the diagnosis

    2010-01-01

    Acanthosis nigricans (AN) is characterized by velvety, hyper pigmented, verrucosus, symmetric and occasionally pruritic plaques along with papillomatous lesions which have a special predilection for neck, axillae, groin, umbilicu and mucosal regions. Rarely, it presents as a para neoplastic syndrome and prompts a thorough search for an internal malignancy. We present here a case of malignant acanthosis nigricans seen in an elderly patient who was found to have underlying adenocarcinoma of the lower end of esophagus. After diagnosing associated malignancy, he was referred for further evaluation and subsequent surgical resection of tumour. (author)

    Scabies is an intensely pruritic disorder induced by a delayed type hypersensitivity reaction to infestation of the skin by the mite Sarcoptes scabiei. The diagnosis of scabies is established clinically and confirmed by identifying mites or eggs by microscopic examination of scrapings from the skin or by surface microscopy using a dermatoscope. Reflectance-mode confocal microscopy is a novel technique used for noninvasive imaging of skin structures and lesions at a resolution compatible to that of conventional histology. Recently, the technique was employed for the confirmation of the clinical diagnosis of scabies. We demonstrate the first ever documentation of a larva moving freely inside the skin of a patient infected with scabies.

    Human scabies affects all social classes and different races around the world. It is highly contagious, but the exact figures on its prevalence are unknown. A 19-year-old male patient was admitted to the emergency room reporting fever (38°C) and multiple lesions throughout the body, except face, soles, and palms. Lesions were non-pruritic, which hampered the initial diagnostic suspicion. Skin biopsy was performed, and the final diagnosis was crusted scabies (Norwegian). It was concluded that human scabies is a significant epidemic disease, due to its different clinical manifestations, and because it is extremely contagious.

    Full Text Available Cold urticaria consists of an allergic immune response to cold temperatures with symptoms ranging from pruritic wheals to life-threatening angioedema, bronchospasm, or anaphylactic shock. Adequate planning to maintain normothermia perioperatively is vital due to impaired hypothalamic thermoregulation and overall depression of sympathetic outflow during deep sedation and general anesthesia. This case report describes the successful perioperative management of a 45-year-old female with a history of cold urticaria undergoing a laparoscopic Nissen fundoplication for refractory gastroesophageal reflux disease and discusses how to appropriately optimize the care of these patients.

    Purpura annularis telangiectodes (PAT), also known as Majocchi purpura, is a rare form of pigmented purpuric dermatosis characterized by non-palpable red-brown, occasionally pruritic patches which progress to hyperpigmented halos. Purpura annularis telangiectodes usually presents in female adolescents as benign symmetric lesions with a predilection for the lower extremities. We present an atypical case of unilateral PAT in an elderly male. To our knowledge, our patient at 85-years-old is the oldest PAT and first unilateral purpura annularis telangiectodes case described in the literature.

    Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

    We report a case of bullous mastocytosis in a 30-month-old girl, who developed disseminated pruritic urticarial and bullous lesions on the trunk accompanied by episodes of vomiting and generalized flushing. Her problems began at the age of 6 months. Her stool was repeatedly positive for occult blood. Histamine and 5-hydroxytryptamine were measured in the urine and serum; urine 5-hydroxytryptamine levels were elevated. In addition, trypsin and chymotrypsin levels were raised in the blister fluid. Metachromatic staining of the mast cells in a skin biopsy specimen confirmed the diagnosis. A combination of oral disodium cromoglycate and ketotifen produced a dramatic improvement of the cutaneous and gastrointestinal features.

    Prurigo pigmentosa is a recurrent inflammatory dermatosis characterized by pruritic erythematous papules and reticulate hyperpigmentation that occurs most frequently in spring and summer. The etiology of prurigo pigmentosa remains unknown. Numerous authors have suggested that various contact allergens may be pathogenic or triggering factors, but nearly all attempts to identify an allergen have been unsuccessful. We report a case of prurigo pigmentosa induced by contact allergy to chrome in detergent, supporting the conclusion that contact allergens such as chrome may play a rôle in inducing prurigo pigmentosa.

    Artificial nails are an increasingly popular cosmetic enhancement to the natural nail. Several forms are available, including sculptured nails, photobonded nails, and preformed nails. Reactions to artificial nails have included paronychia, onychodystrophies, and dermatitis at contact areas and at sites distant to the contactant. We present a patient who developed erythema and painful pruritic vesicles of the paronychial tissue several hours after the application of sculptured nails. A strong reaction of erythema and edema occurred at the site of methyl methacrylate and ethylene glycol dimethacrylate testing. Removal of the artificial nails resulted in resolution of the reaction.

  14. Metastatic Crohn's disease in pediatrics

    Directory of Open Access Journals (Sweden)

    Javier Blasco-Alonso

    Full Text Available Introduction: Metastatic Crohn's disease (MCD is an extraintestinal manifestation of Crohn's disease, with biopsy as fundamental diagnostic tool. There are few References to MCD in children, with a 0.5-1% estimated incidence in adults. There is no consensus about its therapeutic approach. We describe our diagnostic and therapeutic experience in MCD. Case Reports: Four cases of MCD are described in our Pediatric Gastroenterology Unit in a tertiary care hospital. The age at diagnosis was between 7 and 13 years. Lesions appeared before the diagnosis of Crohn's disease in three of them, and during the course of the disease in another one, with genital location in three patients and bilateral pretibial region in the other. All four cases demonstrated non-caseificant granulomas on biopsy. Only two patients used exclusive enteral nutrition therapy with complete resolution, while other two cases received a combination of therapies (corticosteroids, azathioprine, tacrolimus, infliximab and adalimumab because of recurrence. Only one case required surgery after poor clinical control. Discussion: The MCD is infrequent but must always be included in the differential diagnosis of cutaneous lesions in Crohn's disease, considering it could be the debut of the disease. We will rely on biopsy anyway for definitive diagnosis. In this series the genital region is verified as the most commonly affected in children. The therapeutic approach does not differ from the management of intestinal involvement.

    Sonographic examination of the knee has been proposed by several authors in the past as a simple and reliable method to diagnose Osgood-Schlatter disease (OSD). Ultrasound was used to compare the knees of 25 boys and 10 girls with typical OSD with 35 symptom-free knees of an aged-matched group of children. Based on recorded data, patients were categorized (one affected knee in each individual) according to the classification system proposed by De Flaviis et al. in 1989. The results included the following pathological findings: pretibial swelling, fragmentation of the ossification center, insertional thickening of the patellar tendon, and excessive fluid collection in the infrapatellar bursa. Of our patients, 26% fell into the type 1 category, 43% were type 2, 20% type 3, and 11% type 4. This distribution of cases was found to be statistically similar to the initial findings reported by De Flaviis and colleagues. This study therefore supports the validity and reproducibility of their classification method for the ultrasonographic evaluation of children with OSD. This is only the first step, and further assessment of this classification is still required to elucidate its clinical as well as its prognostic value.

    2010-12-01

    Full Text Available Pyoderma gangrenosum is a rare neutrophilic noninfectious dermatose. Etiopathogenesis remains unclear, but in half of cases, there is an associated underlying disease. Inflammatory bowel disease is the most common underlying disorder. Systemic immunosuppressive or immunomodulator drugs and some topical agents are used in treatment of pyoderma gangrenosum. Systemic corticosteroids are the first-choice of treatment. We reported a case with Crohn’s disease associated with pyoderma gangrenosum. She was successfully treated with oral methyl prednisolon. The case was a 54-year-old woman who admitted to hospital because of erythematous, painful plaques on the right and left pretibial surfaces. She had a history of Crohn’s disease, diabetes mellitus, and hypertension. An elevated white blood cell count (13500/μL and high erythrocyte sedimentation rate (120 mm/h were detected. A regime of broad-spectrum antibiotics was started, but response was poor. Histopathological assessment of biopsy specimens showed necrosis, severe edema and erythrocyte extravasations in superficial dermis, regenerative changes in adjacent epithelium, and mixed inflammatory reaction surrounding necrosis in the inner part of the dermis. Based on these clinical and laboratory findings, poor response to antibiotics and underlying disease; her skin lesions were considered as pyoderma gangrenosum. Oral methylprednisolone was started and her skin lesions improved. The steroid dose was tapered and finally stopped under outpatient follow-up. In conclusion, our patient also showed that corticosteroids continue to be the first-choice therapy in pyoderma gangrenosum.

    Carcinoid is a slowly-growing tumor from the group of neuroendocrine or APUD tumors. Characteristic of these tumors is the production of biogene amins & polypeptide hormones. 90% of all carcinoids are located in the GI system. A female patient, 68 years old, comes for a visit with signs of diffuse abdominal pain, diarrhea, irregular bowel movements, weakness, dyspnea and pretibial edemas. The gastroenterologist gives her only symptomatic therapy at first, and starts the examinations after her hospitalization (initial dg: Enterocolitis). One month later she visits again with the same complains. CT scan result shows steatosis hepatica and lots of liquids in the small bowel and colon. She underwent operation--resection of 20 cm of the small bowel with tumor masses and part-time ileostoma. The biopsy of the resected segment of the bowel shows multiple carcinoids. Our patient had no flushing of the skin and therefore couldn't be suspected clinically for this diagnosis. The intestinal carcinoid does not usually produce the carcionid syndrome unless hepatic metastases have occurred. The infiltration of the mesentery provokes an intense fibrotic reaction resulting in kinking of the bowel segments, which causes intestinal obstruction as it happened in this patient. As long as in our clinic we don't have this technique, it is much harder to make an early diagnosis. Fortunately our patient was diagnosed before liver metastases occurred, and therefore her treatment was successful.

    Pericardial effusion is the accumulation of abnormal fluid in the pericardial cavity. The symptoms are not specific and associated with the underlying disease. It was reported that a 53-year-old male patient entered the Emergency Room with a shortness of breath, and getting worse during activity and position. There was weight loss and smoking history. The history of diabetic, hypertension and malignancy were denied. On physical examination showed the enlarged right and left heart border and weakened heartbeat sheer off is found and edema pretibial and normal the other. The laboratory results;blood routine, renal and liver function within normal; lipid profile: hypercholesterolemia; viral marker is non-reactive.Rontgen thorax suggests cardiomegaly, but there was no infiltrate or nodules. Electrocardiogram (ECG) showed a low voltage. Echocardiography examination showed massive pericardial effusion. Pericardiosynthetis performed produces 750 cc of clear yellow liquid and showed transudate. Other laboratory tests such as ANA test, anti ds-DNA, cyfra were a normal impression. Thyroid function: hypothyroid, Mantoux test is negative. Finally, the patient is a massive pericardial effusion caused by hypothyroidism. The pericardiocentesis took, and the hypothyroid drug of euthirax is administered. The patient was well done and continued for recontrol.

    Pancreatic disease can be complicated by extrabdominal manifestations such as panniculitis and polyarthritis. The symptomatic triad comprising pancreatic disease, panniculitis and polyarthritis is also known as PPP syndrome and is characterized by severe chronic sequels and high mortality rate. We describe a case of PPP syndrome successfully treated with spleen preserving total pancreatectomy; in addition we performed a literature review. A 67 years old male presented panniculitis and polyarthritis without clinical abdominal symptoms. Clinical presentation, laboratory values and radiological findings demonstrated an acute pancreatitis and a pancreatic cancer was suspected; failure of conservatory treatments and high suspicious of malignancy led to perform a spleen preserving total pancreatectomy. Finally histological examination excluded a pancreatic cancer and confirmed a chronic pancreatitis. Patient was discharged with complete resolution of the extrabdominal disease. In literature only 64 cases of PPP syndrome have been reported. Abdominal symptoms do not often appear at presentation and diagnosis may be delayed. Panniculitis develope in any part of the body but especially on the distal parts of the lower extremities, around the ankles and pretibial regions of the legs. Between osteo-articular manifestations polyarthritis is the most common one, although oligoarthritis, and monoarthritis in have been reported. PPP syndrome is a rare disease with a high mortality rate. A timely diagnosis and an aggressive treatment may improve the prognosis of this condition. Copyright © 2016 The Authors.

    Necrobiosis lipoidica (NL) is a chronic idiopathic granulomatous disease considered to occur in association with diabetes mellitus. Data on the frequency of this association, however, are inconsistent. Our aim was to retrospectively analyze the clinical characteristics of patients diagnosed with NL at our hospital and to investigate the association with diabetes mellitus and other diseases. We performed a chart review of all patients with a clinical and histologic diagnosis of NL treated and followed in the dermatology department of Hospital de Bellvitge in Barcelona, Spain between 1987 and 2013. Thirty-five patients (6 men and 29 women with a mean age of 47.20 years) were diagnosed with NL in the study period. At the time of diagnosis, 31 patients had pretibial lesions. Thirteen patients (37%) had a single lesion at diagnosis, and the mean number of lesions was 3.37. Twenty-three patients (65.71%) had diabetes mellitus (type 1 in 10 cases and type 2 in 13). In 20 patients, onset of diabetes preceded that of NL by a mean of 135.70 months. The 2 conditions were diagnosed simultaneously in 3 patients. None of the 35 patients developed diabetes mellitus during follow-up. Six patients had hypothyroidism, and 4 of these also had type 1 diabetes. NL is frequently associated with type 1 and 2 diabetes. Although diabetes tends to develop before NL, it can occur simultaneously. Copyright © 2014 Elsevier España, S.L.U. and AEDV. All rights reserved.

  3. Scabies masquerading as bullous pemphigoid: scabies surrepticius

    2017-01-01

    Scabies, a parasitic infestation caused by the mite Sarcoptes scabiei, is diagnosed by observing either the mite, its ova, or its excrement. The mite tracts, known as burrows and a characteristic presentation of the pruritic condition, are typically found on the web spaces between the fingers. Other cutaneous lesions include excoriated papules, pustules, and vesicles. However, atypical clinical variants of scabies, such as bullous, crusted, hidden, incognito, nodular, and scalp forms of the parasitic infestation, mimic the morphologic features of other non-parasitic dermatoses. A 76-year-old man presented with pruritic blisters and urticarial plaques that demonstrated not only pathology changes, but direct immunofluorescence also showed findings of bullous pemphigoid. His condition improved, but did not resolve, with topical corticosteroid cream for the management of the primary autoimmune blistering disorder. When other family members subsequently developed scabies, the correct diagnosis for his condition, bullous scabies, was established by demonstrating mites, ova, and scybala on a mineral oil preparation from a skin scraping of a newly appearing burrow. Bullous scabies can masquerade not only clinically, but also both pathologically and immunologically as bullous pemphigoid. Scabies serrupticius is introduced as a unifying term to designate all of the non-classic presentations of S. scabiei mite infestation. PMID:28883737

    Tattoos have become increasingly common in the United States; however, there are limited data on the rates of tattoo complications and tattoo regret. To determine the rates of infectious and allergic complications after tattooing, rates of tattoo regret, the perception of dermatologists among people with tattoos, and the demographics of people with tattoos. An 18-question cross-sectional survey was fielded in New Orleans in January 2015. Participants had to be at least 18 years old, have at least 1 tattoo, and reside within the United States. In total, 501 participants from 38 American states were enrolled. Of all participants, 3.2% had a history of an infected tattoo, 3.8% had a history of a painful tattoo, and 21.2% had a history of a pruritic tattoo; 16.2% of participants regret a current tattoo and 21.2% are interested in having 1 or more tattoos removed; 21.2% received a tattoo while intoxicated and 17.6% had a tattoo placed somewhere other than at a tattoo parlor; and 78.9% believe dermatologists are knowledgeable about the infectious and allergic complications of tattoos. Given the rates of pruritic tattoos and tattoo regret, there is an opportunity, and trust among people with tattoos, for dermatologists to manage these complications.

    Pregnancy-specific dermatoses include polymorphic eruption of pregnancy, atopic eczema of pregnancy, and pemphigoid gestationis. Intrahepatic cholestasis of pregnancy and impetigo herpetiformis are not real pregnancy-specific dermatoses but they are important to know considering the fetal and maternal risks. Polymorphic eruption of pregnancy is a pruritic disease that usually occurs in primiparous women during the last trimester of pregnancy. Atopic eczema of pregnancy is still controversial as an entity covering conditions with eczematous lesions, prurigo, or folliculitis, and inconstantly associated with a personal history of atopy. Skin biopsy with direct immunofluorescence or search for serum anti-BPAg1 (180kD) NC16a antibodies is mandatory in pruritic dermatoses of pregnancy in order to rule out pemphigoid gestationis. Serum bile salts levels should be tested whenever a generalized pruritus develops during pregnancy in order to rule out intrahepatic cholestasis.

    Atopic dermatitis, a chronic relapsing and pruritic inflammation of the skin also thought to be involved in, or caused by immune system destruction is an upsetting health problem due to its continuously increasing incidence especially in developed countries. Mast cell infiltration in atopic dermatitis skin lesions and its IgE-mediated activation releases various cytokines and chemokines that have been implicated in the pathogenesis of atopic dermatitis. This study was aimed at investigating synergistic anti-inflammatory, anti-pruritic and anti-atopic dermatitis effects of Diospyros lotus leaf extract (DLE) and Muscat bailey A grapefruit stem extract (GFSE) in atopic dermatitis-like induced skin lesions in mice. Combinations of DLE and GFSE inhibited TNF-α and IL-6 production more than DLE or GFSE in PMA plus calcium ionophore A23187-activated HMC-1 cells. DLE and GFSE synergistically inhibited compound 48/80-induced dermal infiltration of mast cells and reduced scratching behavior than DLE or GFSE. Furthermore, DLE and GFSE synergistically showed a stronger ameliorative effect in skin lesions by reducing clinical scores; dermal infiltration of mast cells; ear and dorsal skin thickness; serum IgE and IL-4 production in atopic dermatitis-like mice. Collectively, these results suggest that DLE and GFSE synergistically exhibit anti-atopic dermatitis effects in atopic dermatitis-like skin lesions in mice. Copyright © 2017.

    Excipients are defined as inert substances added to a drug or food to confer a suitable consistency, appearance, or form. They may be added for bulk, to change dissolution or the kinetics of absorption, to improve stability, to influence palatability, or to create a distinctive appearance. The last function may depend heavily on the use of coloring agents, especially when there are multiple dosages (such as with warfarin), and dose confusion may result in profound complications. While described as inert, excipients have been associated with triggering immunological reactions, although this is almost never considered in common practice when patients have reactions to medications, even when they appear to react to many different and distinct drugs. We have found a cohort of 11 patients with chronic, unexplained pruritic skin disorders that have responded to medication changes centered around avoidance of coloring agents, particularly FD&C Blue No. 1 (bright blue) and Blue No. 2 (indigo carmine). We believe that reactions to agents that color medications and foods may be more common than previously appreciated and that recognition of this phenomenon may provide therapeutic alternatives to patients with intractable pruritic disorders.

  9. Recognizing Presentations of Pemphigoid Gestationis: A Case Study

    Full Text Available Introduction. Pemphigoid gestationis (PG is an autoimmune blistering disease that occurs in approximately 1 in 50,000 pregnancies. Failing to recognize PG may lead to inadequate maternal treatment and possible neonatal complications. Case Report. At 18 weeks of gestation, a 36-year-old otherwise healthy Caucasian G4P1 presented with pruritic papules on her anterior thighs, initially treated with topical steroids. At 31 weeks of gestation, she was switched to oral steroids after her rash and pruritus worsened. The patient had an uncomplicated SVD of a healthy female infant at 37 weeks of gestation and was immediately tapered off steroid treatment, resulting in a severe postpartum flare of her disease. Discussion. This case was similar to reported cases of pruritic urticarial papules followed by blisters; however, this patient had palm, sole, and mucous membrane involvement, which is rare. Biopsy for direct immunofluorescence or ELISA is the preferred test for diagnosis. Previous case reports describe severe postdelivery flares that require higher steroid doses. Obstetrical providers need to be familiar with this disease although it is rare, as this condition can be easily confused with other dermatoses of pregnancy. Adequate treatment is imperative for the physical and psychological well-being of the mother and infant.

    Histamine is one of the best-characterized pruritogens in humans. It is known to play a role in pruritus associated with urticaria as well as ocular and nasal allergic reactions. Histamine mediates its effect via four receptors. Antihistamines that block the activation of the histamine H₁receptor, H₁R, have been shown to be effective therapeutics for the treatment of pruritus associated with urticaria, allergic rhinitis, and allergic conjunctivitis. However, their efficacy in other pruritic diseases such as atopic dermatitis and psoriasis is limited. The other histamine receptors may also play a role in pruritus, with the exception of the histamine H₂receptor, H₂R. Preclinical evidence indicates that local antagonism of the histamine H₃receptor, H₃R, can induce scratching perhaps via blocking inhibitory neuronal signals. The histamine H₄receptor, H₄R, has received a significant amount of attention as to its role in mediating pruritic signals. Indeed, it has now been shown that a selective H₄R antagonist can inhibit histamine-induced itch in humans. This clinical result, in conjunction with efficacy in various preclinical pruritus models, points to the therapeutic potential of H₄R antagonists for the treatment of pruritus not controlled by antihistamines that target the H₁R.

  11. Dermatophytosis due to Microsporum nanum infection in a canine

    2017-03-01

    Full Text Available Miscrosporum nanum is a dermatophyte found in swine that causes non-pruritic lesions with desquamation, alopecia, and circular characteristics. M. nanum infection in dogs is rare and poorly understood in terms of its epidemiological and clinical features, and its therapeutic response. The present report describes a case of dermatophytosis due to M. nanum in a Dogo Argentino breed of dog that was used for wild boar hunting. The dermatophytosis presented with hypotrichosis, erythema, and non-pruritic desquamation in the back of the neck and chest area. The dermatophytosis was responsive to systemic treatment with itraconazole and topical (miconazole 2% for 60 days. Thus, we conclude that the practice of hunting wild boar should be considered as a possible source of infection of M. nanum in the reported dog. The M. nanum infection showed clinical features that were similar to the lesions observed in swine, except for the absence of the circular pattern, and showed a good clinical response to the therapy. Finally, M. nanum should be considered as an etiologic agent of dermatophytosis in dogs that in some manner have had direct contact with domestic or wild swine.

    Letterer-Siwe disease is a rare proliferative disorder of the Langerhans cells, usually encountered inpatients under the age of 3 years. We present an unusual case of intrauterine fetal death at the 28th gestational week associated with generalized papular skin eruptions and systemic histiocytic infiltrates characteristic of Letterer-Siwe disease. Histopathologic features of Langerhans cells were further confirmed by immunocytochemistry and electron microscopy. The events occurring in pregnancy which may be worth mentioning are: (1) routine chest P-A view X-ray exposure of the mother 2 days before LMP, (2) the mother was exposed to certain Chinese herbs, in particular, the 101 hair growth solution (A Chinese herb mixture used for alopecia; contents unknown) from assisting her husband in topical applications, and (3) the mother has worked in front of computer monitors 8 hours a day for 10 years.

    Full Text Available ABSTRACT Leishmaniasis is a worldwide tropical infectious disease caused by different species of intracellular protozoa parasites of the genus Leishmania . Herein, we report a 78-year-old man with unusual diffuse cutaneous leishmaniasis (DCL who had a history of opium abuse and chronic obstructive pulmonary disease (COPD. He had multiple papular, crusted and severely ulcerated lesions extended to his arm and chest. Direct smears and skin punch biopsy of the lesions were suggestive of leishmaniasis. Parasite DNA was amplified from ulcers, and identified as Leishmania major by PCR-RFLP, confirmed by sequencing analyses. The aim of the current study was to bring to attention this atypical form of disease in CL endemic countries. Thus, this is the first case of DCL in an opium abuser with COPD due to L. major in Northeastern Iran indicating that atypical and extensive forms of CL (DCL owing to L. major are increasing in Iran.

    Full Text Available Eccrine syringofibroadenoma (ESFA is a rare, benign tumor of eccrine sweat gland origin that usually presents as a nodule on the extremities of an elderly person. It can also present as an ulcerative plaque, verrucous lesion, papular or nodular lesion or as palmoplantar keratoderma. Although the clinical features are variable, histology is characteristic in the form of anastomosing strands, cords and columns of epithelial cells embedded in a fibrovascular stroma. We report the case of a 62-year-old male with a nodular lesion on the extremity that caused secondary involvement of the nail in the form of complete nail dystrophy. The histology showed features consistent with ESFA. Nail involvement by ESFA is a rare presentation and is rarely described in the literature.

    The World Health Organization (WHO) has classified leishmaniasis as an uncontrolled and emerging disease. In Ecuador, the only anecdotal cases of diffuse cutaneous leishmaniasis were recorded in 1994 and have not been formally published. This form can be differentiated from classical localized cutaneous leishmaniasis by the number of injuries, the clinical type of the main elementary lesions (papular and acneform), and a weak response to standard treatments. The case we report is a 34-year-old woman who presented with disseminated nodular lesions and ulcers of various sizes with erythematous edges and scars. We report the case and review diffuse cutaneous leishmaniasis and the differences that can be found with the other cutaneous variants. The diagnosis requires to be considered by primary care physicians in endemic areas and specialists, taking into account that this presentation can also occur in immunocompetent hosts.

  18. Comparative clinicopathological study on pityriasis lichenoides chronica and small plaque parapsoriasis.

    Benmamán, O; Sánchez, J L

    1988-06-01

    The term parapsoriasis refers to a group of chronic asymptomatic scaly dermatoses of unknown etiology about which there is still controversy over the nosology and nomenclature of the different conditions that comprise the group, particularly pityriasis lichenoides chronica (PLC) and small plaque parapsoriasis (SPP). In an attempt to establish the distinctive clinicopathologic features of these two dermatosis, we prospectively studied 44 patients who presented with the typical clinical and histologic picture of either of these two diseases. SPP was clinically characterized by scaly oval plaques on the trunk and proximal aspect of extremities. Spongiosis was the salient histopathologic feature, with absence of fibrosis or melanophages. PLC presented with a scaly papular eruption over the trunk and extremities and histologically was characterized by an interface dermatitis. We conclude that sufficient clinical and histologic features differentiate these two entities and we propose that the term parapsoriasis be used only to designate SPP and large plaque parapsoriasis.

    2013-01-01

    An 18-year-old female presented with a severe ulcerative lesion on her right ear of 6 weeks duration. Her right ear was edematous and erythematous with a large, painless ulcerative lesion covering a third of the pinna and satellite papular lesions on the posterior. She was diagnosed with chiclero's ulcer. A skin smear stained with Diff-quik showed abundant Leishmania parasites. Chiclero's ulcer is a rare clinical presentation and is typically severe and difficult to treat. Physicians in Ecuador recommend administering prolonged intramuscular Glucantime. Side effects are common and can be severe resulting in low patient compliance. Because of preferences of the patient and the large volume needed for her weight, we recommended topical treatment with a lotion of Glucantime mixed half and half with white Merthiolate. After applying this lotion to the lesion 3 to 4 times a day for 6 weeks, the lesion healed. PMID:23926136

    The colour of a lesion is due to its nature and to its histological substratum. In order to ease diagnosis, oral cavity lesions have been classified according to their colour in: white, red, white and red, bluish and/or purple, brown, grey and/or black lesions. To the best of our knowledge, there is no such a classification for yellow lesions. So, a suggestion for a classification of yellowish lesions according to their semiology is made with the following headings: diffuse macular lesions, papular, hypertrophic, or pustular lesions, together with cysts and nodes. This interpretation of the lesions by its colour is the first step to diagnosis. It should be taken into account that, as happens with any other classification, the yellowish group of lesions includes items with different prognosis as well as possible markers of systemic disorders.

    Full Text Available Xanthelasmoid or pseudoxanthomatous mastocytosis is an extremely rare variant of diffuse cutaneous mastocytosis. Herein, we describe an adult male with cutaneous mastocytosis showing multiple widespread yellowish ovoid papules like eruptive xanthoma. A 60-year-old male visited our outpatient clinic with a 1-year history of generalized yellowish, ovoid, and skin color papular eruption located on the trunk, groin, extremities, with the modest pruritus. Vital signs were stable, and Darier′s sign was negative. No other subjective and objective signs were detected during the examination. No abnormality was detected in his diagnostic laboratory tests. Skin biopsy was taken, and histopathologic examination revealed proliferation of mast cells with ovoid and spindle nuclei with distinct cytoplasm borders around the capillaries, which was compatible with mastocytosis. Antihistamine was prescribed for pruritus control which was successful, but eruptions were persistent, and even 1-year phototherapy was not useful.

    Mucha-Habermann disease is a cutaneous clinical manifestation of unknown etiology that frequently appears in young patients. The aim was to present Mucha-Habermann disease that occurred in an old man who had a heart transplant. a 62 year-old male, heart transplant recipient, who four years after that transplantation procedure presented with papular lesions in neck, thoracic members of which extended to all body surfaces and that evolved vesicles and pustular lesions. A skin biopsy was performed and Mucha-Habermann disease was diagnosed. The patient was treated with steroids and antimicrobial therapy with favorable response. After two years there are no skin lesions. Mucha-Habermann disease is a low frequency disease and it requires skin biopsy to confirm diagnose. This is an uncommon case due to the age and kind of patient.

    Cutaneous tuberculosis continues to be an important public health problem even with the availability of highly effective anti-tuberculous drugs. It constitutes 0.1% of all cases of extrapulmonary tuberculosis. Lupus vulgaris is the most common form of cutaneous tuberculosis that occurs in previously sensitized individuals with a moderate degree of immunity against tubercle bacilli. The different types of lupus vulgaris include plaque, ulcerative, vegetative, papular and nodular, and tumor forms. A 40-year-old man presented with large multiple plaques over right upper limb, right side of chest and back, and right lower limb for the past 30 years. Histopathology showed numerous noncaseating granulomas with Langhan's type of giant cells. The Mantoux test showed strong positivity and there was excellent response to anti-tuberculous treatment. This case is being reported because of its extreme chronicity of 30 years duration, unusually large size and multiplicity of lesions.

    Full Text Available Aim: to evaluate the picture of dermatoscopy in case of psoriasis at different stages of the disease. Materials and Methods. We observed 30 patients with a diagnosis of disseminated papular — plaque psoriasis at the stage of progression. Dermatoscopic study was conducted by the expert class videodermatoskop MoleMaxHD (company Derma Medical Systems, Austria, with an increase from x30 to x80 to initiation of therapy, on the 7th and 15th days of treatment. Results. Changes of dermatoscopic picture in psoriasis are observed on the first days of treatment, and outperformed the major clinical manifestations of infections detected by the human eye. Conclusion. Dermatoscopy reveals the earliest signs of positive dynamics of the therapy and can be used to select a rational method of treatment.

    We report a familial form of rheumatoid nodulosis where the early lesions appeared in the first years of life in a young man and his son. The numerous papular and nodular skin lesions disclosed an ulcerative evolution leaving atrophic scars mainly near the limbs' joints. In both patients the evolution was characterized by the late onset of polyarthralgias and of a non-destructive seronegative polyarthritis; intra-osseous lesions were present in the metatarsal bones in the father. Rheumatoid nodulosis is a rare disease, sometimes considered as a benign variant of rheumatoid arthritis without destructive joint involvement. A serum rheumatoid factor is inconstantly present and the intra-osseous geodes have been shown to be rheumatoid nodules exhibiting the same histological structures of palisading granulomas as the subcutaneous nodules. The main symptom of the disease is the occurrence of multiple nodules followed by the delayed onset of a polyarthritis with a benign course without systemic involvement.

    Full Text Available Introduction: Herpes Zoster (HZ is rare in infancy and results from reactivation of varicella-zoster virus, latent in the dorsal root ganglia of sensory or cranial nerves after primary infection (chickenpox. Case Report: We describe the case of an healthy infant, three months old, without previous clinical symptoms of chickenpox, in spite of having contacted with the disease at two weeks of life. She was hospitalized for vesicular-papular rash involving unilaterally dermatomes L4 and L5 and was treated with acyclovir with good clinical outcome. Conclusion: The immaturity of the immune system and the interference of maternal antibodies contribute to the manifestation of HZ in the first year of life. In a previously healthy child it is not recommended the exclusion of underlying immunodeficiency or malignant disease.

    2015-01-01

    Eccrine syringofibroadenoma (ESFA) is a rare, benign tumor of eccrine sweat gland origin that usually presents as a nodule on the extremities of an elderly person. It can also present as an ulcerative plaque, verrucous lesion, papular or nodular lesion or as palmoplantar keratoderma. Although the clinical features are variable, histology is characteristic in the form of anastomosing strands, cords and columns of epithelial cells embedded in a fibrovascular stroma. We report the case of a 62-year-old male with a nodular lesion on the extremity that caused secondary involvement of the nail in the form of complete nail dystrophy. The histology showed features consistent with ESFA. Nail involvement by ESFA is a rare presentation and is rarely described in the literature.

  10. Criterion for inclusion in onchocerciasis control programmes based on ivermectin distribution.

    1995-01-01

    Data on onchocercal lymphatic and skin lesions from 45 communities located in the West African savanna were analysed to determine if the criterion for inclusion in ivermectin mass treatment based on risk of onchocercal blindness needs to be modified. Only 16 cases of elephantiasis were reported among 10,108 people examined. Other lymphatic lesions were almost exclusively found in people older than 30 years living in villages at risk of onchocercal blindness. Permanent skin lesions also affected older people and were 3 times more frequent in villages at risk of onchocercal blindness. Papular rash and pruritus affected younger people. No evidence was, therefore, found to change the criterion based on risk of onchocercal blindness presently in use in savanna areas.

Luego de cinco días de haber permanecido en una región cercana a la localidad de ingeniero Otamendi, partido de Campana, el paciente presentó un síndrome febril agudo caracterizado por hipertermia con escalofríos y sudoración, mialgias, cefalea, astenia y discreta odinofagia, seguido a las 72 horas por un exantema maculopapuloso congestivo con elementos purpúricos, de distribución universal. En la región preauricular izquierda se observaba una lesión papuloerosiva, producida cinco días antes de iniciada la fiebre por una garrapata adquirida en el lugar. El cuadro clínico remitió rápidamente con la administración de doxiciclina. Por inmunofluorescencia indirecta se identificaron anticuerpos reactivos contra el grupo de rickettsias causantes de fiebres manchadas (CDC, Atlanta, EE.UU.. Se realizan consideraciones sobre la especie de rickettsia, el vector involucrado y la posibilidad que la enfermedad fuera debida a Rickettsia parkeri.We describe a case of rickettsial spotted fever in the Paraná Delta region of Buenos Aires province in Argentina. The patient developed an acute febrile syndrome characterized by myalgias, headache, asthenia and moderate odynophagia, followed by a diffuse macular, papular, and purpuric exanthema. The patient had been bitten recently by a tick on the left preauricular region and an erosive papular lesion was evident at the bite site. An indirect immunofluorescence antibody assay identified antibodies reactive with spotted fever group rickettsiae in the patient's serum. The patient improved rapidly with doxycycline. Several considerations relating to the identity of the rickettsial species and tick vector are discussed, including the possibility that this patient's illness may have been caused by Rickettsia parkeri.

    Urticaria is a common cause for consultation in general and specialised medical practices. There is scarce information on the characteristics of patients suffering acute urticaria in Latin America. To investigate demographic and clinical features of patients with acute urticaria attending two allergy clinics in Caracas, Venezuela. A prospective study of all new patients who consulted during a three-year period because of acute urticaria. Information on age, gender, symptom duration, previous medical history, body distribution of wheals and angio-oedema, laboratory investigations, skin prick tests, and pharmacological treatment, was collected. Patients were classified according to their age as children/adolescents and adults. Two hundred and forty eight patients (177 adults and 71 children) were studied. Acute urticaria was more frequent in middle-aged atopic female patients. Lesions more often involved upper and lower limbs and head, and 31% of patients exhibited generalised urticaria. Laboratory investigations, performed only in selected cases, did not contribute to the final diagnosis. Most frequent subtypes of acute urticaria were spontaneous, dermographic, papular, and drug-induced urticaria. Most patients were treated with non-sedating antihistamines, with increased use of cetirizine and levocetirizine in children, while 5.6% of children and 20.3% of adults required the addition of short courses of systemic corticosteroids. Acute urticaria is a frequent cause of consultation for allergists, affecting more often middle-aged female atopic patients. The use of extensive complementary tests does not seem to be cost-effective for this clinical condition. Spontaneous, dermographic, papular and drug-induced urticaria are the most common subtypes.

    Thrombotic microangiopathies are a group of diseases presenting as microangiopathic hemolytic anemia, thrombocytopenia and end-organ dysfunction. As the role of the complement system was elucidated in atypical hemolytic uremic syndrome pathogenesis, eculizumab was successfully introduced into clinical practice. We present a large pedigree with multiple individuals carrying a functionally significant novel factor H mutation. We describe the proband's presentation following a presumed infectious trigger requiring plasma exchange and hemodialysis. A 32-year-old Caucasian woman presented with pyrexia and headache lasting one week to our Emergency Department. She gave no history of diarrhea or other symptoms to account for her high temperature. She was not taking any medication. She was pyrexial (38°C), tachycardic (110 bpm) and hypertensive (160/110 mmHg). Her fundoscopy revealed grade IV hypertensive retinopathy. She had mild pretibial and periorbital edema, with oliguria (450 mL/day). She had a pregnancy one year previously, during which she had hypertension, proteinuria and edema, with successful delivery at term. Her mother had died in her early 30s with a clinical picture consistent with thrombotic microangiopathy. Her laboratory evaluation showed microangiopathic hemolytic anemia. After 22 sessions of plasma exchange, her lactate dehydrogenase levels started to climb. As a result, she was classified as plasma resistant and eculizumab therapy was instituted. Her lactate dehydrogenase level and platelet count normalized, and her renal function recovered after three months of dialysis. We demonstrate that, even in patients with atypical hemolytic uremic syndrome and prolonged dialysis dependence, recovery of renal function can be seen with eculizumab treatment. We suggest a treatment regime of at least three months prior to evaluation of efficacy.

    Infection commonly complicates diabetic foot ulcers and is associated with a poor outcome. In a cohort of individuals with an infected diabetic foot ulcer, we aimed to determine independent predictors of lower-extremity amputation and the predictive value for amputation of the International Working Group on the Diabetic Foot (IWGDF) classification system and to develop a risk score for predicting amputation. We prospectively studied 575 patients with an infected diabetic foot ulcer presenting to 1 of 14 diabetic foot clinics in 10 European countries. Among these patients, 159 (28%) underwent an amputation. Independent risk factors for amputation were as follows: periwound edema, foul smell, (non)purulent exudate, deep ulcer, positive probe-to-bone test, pretibial edema, fever, and elevated C-reactive protein. Increasing IWGDF severity of infection also independently predicted amputation. We developed a risk score for any amputation and for amputations excluding the lesser toes (including the variables sex, pain on palpation, periwound edema, ulcer size, ulcer depth, and peripheral arterial disease) that predicted amputation better than the IWGDF system (area under the ROC curves 0.80, 0.78, and 0.67, respectively). For individuals with an infected diabetic foot ulcer, we identified independent predictors of amputation, validated the prognostic value of the IWGDF classification system, and developed a new risk score for amputation that can be readily used in daily clinical practice. Our risk score may have better prognostic accuracy than the IWGDF system, the only currently available system, but our findings need to be validated in other cohorts. © 2015 by the American Diabetes Association.

    Basic pathology in thermal injury is coagulative soft tissue necorsis that may occasionally be complicated by infection and later by scarring and vascular changes. Radiological features were discussed in detail by Resnick. The early changes consist of soft tissue defect, porosis and periostitis and the late changes include osteophytosis, periarticular calcification or ossification and arthropathy with ankylosis. Acromutilation can occur when small bones of the hand and foot are burned and scarred. This communication describes {sup 99m}Tc-HDP pnhole bone scan manifestations of thermal bone injuries observed in a case of skin-bone burns of the mid-tibial shaft that was complicated by infection, soft tissue scarring and osteonecrosis. Patient was a 49-year-old female thermal burn involving a mid-tibial shaft segment along with overlying skin. The injury was accidental to medullary rimming to fit intramedullary nail to fix fracture. The heat produced during drilling spread to burn the pretibial skin that is sparse in subcutaneous buffer tissue and vessels. The soft tissue burn was infected and healed by repeated skin grafts and scar over a period of 2 years. Concomitantly, the underlying bone was infected locally and treated but ensued in osteonecrosis that was accompanied by osteolysis. Indeed. pinhole {sup 99m}Tc-HDP scan played a unique role in this case in detecting that live lateral cortex had sustained the large dead bone that involved the main volume of the mid-tibial shaft. Importantly, the scan could confirm live cortex to have sustained dead bone uncollapsed. Anatomical and metabolic data gained from bone scanning prompted us to systematically scrutinize radiograph and CT to specifically identify the preserved lateral cortex. As mentioned the existence of healthy cortex is biomechanically and tactically vital to surgically replace and restore the devitalized bone.

  16. Accuracy of physical examination in the diagnosis of hypothyroidism: a cross-sectional, double-blind study

    Full Text Available Background: Hypothyroidism is a common, potentially treatable endocrine disorder. Since hypothyroidism is not always associated with the signs and symptoms typically attributed to it, the diagnosis is often missed. Conversely, patients with typical signs and symptoms may not have the disease when laboratory tests are performed. Aims: We aimed to determine the accuracy of physical examination in the diagnosis of hypothyroidism. Setting and design: Prospective, hospital-based, cross-sectional diagnostic study. Material and Methods: Consecutive outpatients from the medicine department were screened and an independent comparison of physical signs (coarse skin, puffy face, slow movements, bradycardia, pretibial oedema and ankle reflex against thyroid hormone assay (TSH and FT4 was performed. Statistical analysis: Diagnostic accuracy was measured as sensitivity, specificity, positive likelihood ratios, negative likelihood ratios and positive and negative predictive values. Results: Of the 1450 patients screened, 130 patients (102 women and 28 men underwent both clinical examination and thyroid function tests. Twenty-three patients (18% were diagnosed to have hypothyroidism by thyroid hormone assays. No single sign could easily discriminate a euthyroid from a hypothyroid patient (range of positive likelihood ratio (LR+ 1.0 to 3.88; range of negative likelihood ratio (LR-: 0.42 to 1.0. No physical sign generated a likelihood ratio large enough to increase the post-test probability significantly. The combination of signs that had the highest likelihood ratios (coarse skin, bradycardia and delayed ankle reflex was associated with modest accuracy (LR+ 3.75; LR- 0.48. Conclusion: Clinicians cannot rely exclusively on physical examination to confirm or rule out hypothyroidism. Patients with suspected hypothyroidism require a diagnostic workup that includes thyroid hormone assays.

    2017-12-01

    Full Text Available This case describes an obese adult male peritoneal dialysis patient who presented with a pruritic follicular rash. Nutrient deficiency was not suspected initially in this case because there was no history of protein-calorie malnutrition, but the patient reported a diet devoid of fruits and vegetables and had not been taking his dialysis vitamin as prescribed. Skin biopsy showed follicular hyperkeratosis with fragmented hair shafts and corkscrew hairs consistent with scurvy. After supplementation with ascorbic acid 500 mg twice daily for 2 weeks, the rash resolved completely. Dialysis patients are at increased risk for vitamin C deficiency due to indiscriminant clearance of the nutrient with dialysis, but scurvy is rarely seen.

    2015-06-01

    A 9-year-old castrated domestic shorthair cat was presented with a 6 week history of progressive non-pruritic alopecia, polyphagia and weight loss. A diagnosis of lymphocytic mural folliculitis was made and the cat was treated with a combination of prednisolone and ciclosporin; this produced an improvement in the alopecia but no resolution. Sixteen months after the initial assessment and diagnosis, the cat was re-evaluated for intermittent vomiting and weight loss with normal appetite. On examination the dermatopathy was still evident and a mass involving the duodenum and pancreas was present, which was diagnosed as a pancreatic carcinoma. From this case it would appear that lymphocytic mural folliculitis might be an early dermatological manifestation of pancreatic neoplasia. © ISFM and AAFP 2014.

    Chronic myelogenous leukaemia was diagnosed in a 7-year-old male neutered domestic shorthair cat. Leukocytosis (74,900/µl)--mature neutrophilia, eosinophilia and basophilia--was observed. Bone marrow aspiration revealed hypercellularity with proliferation of cells of myeloid lineage. An underlying condition leading to leukocytosis was not identified. The severe leukocytosis did not respond to antibiotic therapy. Based on these findings, chronic myelogenous leukaemia was diagnosed. Because of the absence of clinical signs, the cat was monitored without treatment until 7 months after diagnosis, when it developed pruritic skin lesions. Pruritus was controlled with oral prednisolone. Forty-two months after diagnosis, the cat developed nasal lymphoma, which was treated with radiation therapy, resulting in complete remission. The cat was still in good physical condition 63 months after diagnosis, despite the persistence of marked neutrophilia, eosinophilia and basophilia. © ISFM and AAFP 2013.

    2015-08-01

    Full Text Available SUMMARY Chagas disease (CD is an endemic anthropozoonosis from Latin America of which the main means of transmission is the contact of skin lesions or mucosa with the feces of triatomine bugs infected by Trypanosoma cruzi. In this article, we describe the first acute CD case acquired by vector transmission in the Rio de Janeiro State and confirmed by parasitological, serological and PCR tests. The patient presented acute cardiomyopathy and pericardial effusion without cardiac tamponade. Together with fever and malaise, a 3 cm wide erythematous, non-pruritic, papule compatible with a "chagoma" was found on his left wrist. This case report draws attention to the possible transmission of CD by non-domiciled native vectors in non-endemic areas. Therefore, acute CD should be included in the diagnostic workout of febrile diseases and acute myopericarditis in Rio de Janeiro.

  1. Ignoring the "Itch": The Global Health Problem of Scabies.

    Science.gov (United States)

    Stamm, Lola V; Strowd, Lindsay C

    2017-12-01

    Infestation with Sarcoptes scabiei var. hominis is a common human parasitic affliction endemic in tropical developing countries. Scabies is transmitted by close person-person contact, and outbreaks have been reported in reception centers for asylum seekers. Scabies presents clinically as extremely pruritic excoriated papules and linear burrows in the skin. This infestation predisposes to bacterial skin infections that can result in serious complications affecting the kidneys and possibly the heart. Treatment of individuals with scabies and their close contacts involves the use of antiparasitic agents. First-line treatment is topical 5% permethrin cream. Community mass drug administration, followed by active case finding with targeted treatment, is a promising approach that can reduce the prevalence of both scabies and bacterial skin infections. Organizations such as the International Alliance for the Control of Scabies are advocating for the development of integrated disease control strategies in an effort to decrease scabies infestation worldwide.

    2018-04-01

    Red man syndrome (RMS) is a well-known hypersensitivity reaction caused by intravenous administration of vancomycin, with symptoms ranging from flushing, erythematous rash, pruritus, mild to profound hypotension, and even cardiac arrest. RMS has not previously been described from local application of vancomycin powder in a surgical wound, a technique increasingly utilized for infection prophylaxis in many surgical disciplines including neurosurgery. We describe the first reported case of RMS as a result of local intra-wound application of vancomycin powder for infection prophylaxis. A 73-year-old male with a history of Parkinson's disease underwent 2-stage deep brain stimulation implantation surgeries. Vancomycin powder was applied locally in the surgical wounds for infection prophylaxis during both of the surgeries. The patient developed a well-demarcated, geometric erythematous pruritic rash following the second surgery that was clinically diagnosed as RMS and resolved without sequelae.

    Full Text Available We report a case of a 35-year-old female who presented to the emergency room (ER complaining of a pruritic rash involving multiple areas of the body. She had a significant history of cocaine use in the past. She had first developed a similar rash in 2013 when she was diagnosed with cocaine-induced vasculitis. Her urine toxicology had been positive for cocaine in the past until July 2013. She was incarcerated and attended a drug rehabilitation program after which she quit cocaine use, which was consistent with negative urine toxicology on subsequent admissions. Further workup did not reveal any other, autoimmune or infectious, etiology of this clinical presentation. The patient underwent biopsy of the skin lesion that was consistent with thrombotic vasculopathy likely secondary to levamisole.

    Full Text Available Objective: To evaluate the effectiveness of steroid and 5-fluorouracil (5-FU injection combination for keloid management. Methods: A 22-year-old female patient was presented with recurrent skin lesions. The skin lesions first appeared 10 years prior to consultation, had been surgically excised, and were given triamcinolone acetonide injection. However, no improvement was observed. A decision was made to use and evaluate treatment using an intralesional 4 mg (0.1 ml of 40 mg/ml triamcinolone acetonide and 45 mg (0.9 ml of 50 mg/ml 5-FU injection combination for 5 weeks. Results: Clinical improvements were observed in the third week as the lesions softened and pruritic sensation dinimished. At the end of the fifth week, improvements in the form of keloid lesion flattening and size reduction were observed. Conclusions: Intralesional injection using a combination of triamcinolone acetonide and 5-fluorouracil is effective for keloid lesion treatment.

    Ferreira, M. R.; Amado, A.; Jorge, M.; Grillo, I. M.

    2011-01-01

    Background: Stevens Johnson Syndrome and Erythema Multiforme are hypersensitivity skin reactions generally arising in the context of multiple causes. Radiation therapy is considered to be one of these causes, although most reports are hindered by concomitant medications. Aim: The aim of this paper was to present a case of Stevens Johnson Syndrome arising in a patient undergoing gynaecological brachytherapy with an unusual presentation. Case:We describe a case of a 56-year-old woman with endometrial cancer undergoing adjuvant gynaecological radiotherapy. While undergoing a gynaecological brachytherapy boost, she developed bilateral conjunctivitis that progressed to oral mucositis and pruritic erythema with sloughing of the skin on her arms and legs but not the torso or irradiated fields (namely the vaginal mucosa). Conclusion: This case illustrates the association of RT/SJS; however, it also raises the question of patients undergoing RT being more susceptible to SJS as opposed to a direct cause of the disease.

    Full Text Available Prurigo nodularis (PN is chronic unbearable inflammatory skin disease. Although it was described before a century, not many studies have been conducted regarding the systemic treatment of prurigo nodularis. A 64-year-old male patient has moderate to severe atopic dermatitis superimposed by disseminated pruritic nodules over the trunk and extremities. In spite of topical treatment and Phototherapy, patient condition was deteriorating. Therefore, the patient was treated with multimodalities including high potency topical steroid, intravenous antihistamine, cyclosporine and omalizumab without improvement. Thus the patient has been treated with methotrexate which led to remarkable improvement. Management of prurigo nodularis is often challenging as the etiology of PN in the majority of the cases is unknown. Conservative treatments are often inefficient. This case proves the efficacy of methotrexate in the management of prurigo nodularis.

    Full Text Available Context Atopic dermatitis is a chronic, relapsing skin disorder that affects all ages including infancy and childhood. There are many proved and unproved treatments for atopic dermatitis. Evidence Acquisition Data sources of this narrative review included studies about pediatric atopic dermatitis with the following keywords, pediatric, atopic dermatitis, immunity, acute, chronic, pruritic inflammatory skin disorder, infancy, childhood, diagnosis, management and treatment. All of the articles were written in English language with full text on management or treatment. Results Innate and adaptive immune system involved atopic dermatitis. Major characteristics of atopic dermatitis include pruritus, chronic or relapsing lesions and personal or family history of atopic disease. There is no specific treatment for atopic dermatitis. The treatment included rehydration, emollients, topical steroid, calcineurin inhibitors and immunosuppressant. Crisaborole topical ointment, a PDE4 anti-inflammatory topical agent (phase three of the research could be effective in atopic dermatitis. Conclusions Avoidance from trigger factors and emollients are basic treatments of atopic dermatitis.

    2016-07-15

    A 55-year-old woman presented with a 3-year history of recurrent episodes of pruritic cellulitis-like erythematous plaques, mostly located on the limbs. Simultaneously, fever, malaise and peripheral eosinophilia were noted. The clinical diagnosis of eosinophilic cellulitis (also known as Well's syndrome) was supported by the histopathological finding of typical "flame figures". Treatment with dapsone was initiated at a dose of 50 mg per day. After one year of follow-up the patient was relapse-free. Eosinophilic cellulitis is an uncommon, recurrent inflammatory skin disease. The management is often a challenge, due to the frequent need for long-term therapy. Dapsone is an effective and safe treatment option.

    Palmoplantar lichen planus is an uncommon dermatosis. We present a case of 38-year-old Caucasian male with a history of pruritic, scaly lesions on the right plantar foot. Physical examination revealed whitish plaques and numerous spiny hyperkeratotic papules and focal scaling. A biopsy demonstrated orthohyperkeratosis and acanthosis of the epidermis. Immunohistochemical staining revealed positivity within the epidermis and/or lichenoid infiltrate with CD3, CD8, CD45, CD68, myeloid histiod antigen, BCL2, p27, p53, HLA-DPDQDR, metallothionein and tissue inhibitor of metalloproteinases 1. The diagnosis of PPLP was thus confirmed; this case illustrates that PPLP should be considered in the differential diagnosis of uncommon foot dermatoses with a significant junctional inflammatory component.

    Full Text Available Lymphomatoid contact dermatitis (LCD is a rare variant of noneczematous allergic contact dermatitis, which can mimick parapsoriasis or early-stage mycosis fungoides with its atypical clinical and histopathological manifestation. Many different haptens have been reported to be associated with this reaction. Histopathological examination, immunhistochemistry, clonality tests, and patch tests are mandatory for diagnosis and differential diagnosis. We present a 48-year-old male with a four years history of a relapsing erythematous plaque on the glans penis. Topical corticosteroids had been prescribed but he complained of relapse upon withdrawal. Histopathological examination was consistent with LCD. Thin layer rapid use epicutaneous patch test result was (++ for disperse blue and nickel sulfate. We present this case because of its rarity and unusual localization. This kind of allergic contact dermatitis should be remembered in differential diagnosis of nonspesific pruritic plaques over the genital region.

    Atopic dermatitis (AD) is a familial and chronic inflammatory pruritic skin disease that affects a large number of children and adults in industrialized countries. It is known that one of the prominent features of AD and chronic pruritus is partially due to the histamine released from mast cell. In this work, hydrogel patches with natural herbal extracts were prepared by 'freezing and thawing', and a gamma irradiation. It showed eminent healing results as a consequence of long-term moisturizing effects and natural herbal extracts on atopic wounds. Besides its non-toxicity and human harmlessness, it can be easily attached to or detached from the skin without any trace and help patients to feel refreshment when attached. Based on this work, the hydrogel patches we made can be potentially used as an alternative remedy for not only pruritus in AD, but other dermatitis.

    Atopic dermatitis is an extremely common, pruritic, and frustrating disease to treat in both people and animals. Atopic dermatitis is multifactorial and results from complex interactions between genetic and environmental factors. Much progress has been done in recent years in terms of understanding the complex pathogenesis of this clinical syndrome and the identification of new treatments. As we learn more about it, we appreciate the striking similarities that exist in the clinical manifestations of this disease across species. Both in animals and people, atopic disease is becoming increasingly common and important similarities exist in terms of immunologic aberrations and the propensity for allergic sensitization. The purpose of this review is to highlight the most recent views on atopic dermatitis in both domestic species and in people emphasizing the similarities and the differences. A comparative approach can be beneficial in understanding the natural course of this disease and the variable response to existing therapies.

    2016-05-01

    Teriparatide, or recombinant human parathyroid hormone, is approved for the treatment of osteoporosis. Possible cutaneous adverse events of teriparatide are urticaria, injection site pain, swelling, bruising, and pruritus. However, there have been no reports of widespread eczematous reactions caused by teriparatide. A 47-year-old male was recently diagnosed with osteogenesis imperfecta and prior to teeth extractions, he was subcutaneously injected with teriparatide. The patient developed multiple pruritic erythematous papules and plaques on his abdomen, around the site of the injection. A skin biopsy was done, which showed mild spongiosis and superficial perivenular lymphocytic infiltration with a few eosinophils. Drug-related eczematous changes were most likely suspected and in addition to the discontinuation of the injection, topical steroid was prescribed, in which dramatic improvements were observed. We report the eczematous hypersensitivity reaction caused by teriparatide, which is an adverse reaction that has not been reported before.

  16. Atopic dermatitis in the domestic dog.

    Pucheu-Haston, Cherie M

    2016-01-01

    Dogs may develop a syndrome of spontaneous, inflammatory, pruritic dermatitis that shares many features with human atopic dermatitis, including a young age of onset, characteristic lesion distribution, immunoglobulin E sensitization to common environmental allergen sources, and evidence of epidermal barrier dysfunction. There are also several important differences between canine and human atopic dermatitis. Although dogs may suffer from multiple-organ hypersensitivity syndromes, there is no evidence that this species experiences the progressive evolution from cutaneous to respiratory allergy characteristic of the human atopic march. Despite the presence of epidermal barrier derangement, there is no significant association between canine atopic dermatitis and mutations in filaggrin. Finally, treatment of canine disease relies much less heavily on topical therapy than does its human counterpart, while allergy testing and allergen-specific immunotherapy provide an often essential component of effective clinical management of affected dogs.

    Lyons, Jonathan J.; Milner, Joshua D.; Stone, Kelly D.

    2014-01-01

    Atopic dermatitis (AD) is a chronic, relapsing, highly pruritic skin condition resulting from disruption of the epithelial barrier and associated immune dysregulation in the skin of genetically predisposed hosts. AD generally develops in early childhood, has a characteristic age-dependent distribution and is commonly associated with elevated IgE, peripheral eosinophilia and other allergic diseases. Staphylococcus aureus colonization is common and may contribute to disease progression and severity. Targeted therapies to restore both impaired skin barrier and control inflammation are required for optimal outcomes for patients with moderate to severe disease. Pruritus is universal among patients with AD and has a dominant impact on diminishing quality of life. Medications such as anti-histamines have demonstrated poor efficacy in controlling AD-associated itch. Education of patients regarding the primary underlying defects and provision of a comprehensive skin care plan is essential for disease maintenance and management of flares. PMID:25459583

    Atopic dermatitis is a pruritic inflammatory skin disorder, involving immunological and non-immunological factors. Substance P seems to be involved in the pathogenesis of atopic dermatitis. Substance P-containing nerve fibers are increased in the lesional skin of patients with atopic dermatitis and a reduced weal and flare reaction to intradermal injection of substance P has been observed. We investigated the distribution of substance P receptors in the involved skin of patients before and after single or repetitive UVA irradiations. Our results indicate that substance P receptors of the NK-1 subtype are expressed on blood vessels and on epidermal keratinocytes of involved skin of patients with atopic dermatitis. UVA irradiations did not modify the epidermal distribution of substance P receptors but decreased their expression intensity on blood vessels. UVA irradiations seem to decrease skin inflammation through the modulation of NK-1 receptor expression on endothelial cells.

  2. Bee Venom Phospholipase A2 Alleviate House Dust Mite-Induced Atopic Dermatitis-Like Skin Lesions by the CD206 Mannose Receptor.

    2018-04-02

    Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by highly pruritic, erythematous, and eczematous skin plaques. We previously reported that phospholipase A2 (PLA2) derived from bee venom alleviates AD-like skin lesions induced by 2,4-dinitrochlorobenzene (DNCB) and house dust mite extract ( Dermatophagoides farinae extract, DFE) in a murine model. However, the underlying mechanisms of PLA2 action in actopic dermatitis remain unclear. In this study, we showed that PLA2 treatment inhibited epidermal thickness, serum immunoglobulin E (IgE) and cytokine levels, macrophage and mast cell infiltration in the ear of an AD model induced by DFE and DNCB. In contrast, these effects were abrogated in CD206 mannose receptor-deficient mice exposed to DFE and DNCB in the ear. These data suggest that bvPLA2 alleviates atopic skin inflammation via interaction with CD206.

    2012-02-01

    Ichthyosiform mycosis fungoides (MF) is a recently recognized clinical variant of MF, which appears as dry scaling patches and plaques, or as a generalized eruption. Acquired ichthyosis is well recognized as a paraneoplastic cutaneous presentation of malignancy, especially in lymphoproliferative disorders. In contrast, the ichthyosiform eruption in ichthyotic MF is attributable to infiltration of the skin by tumour cells. We report the case of a 15-year-old boy who presented with a 5-year history of enlarging pruritic plaques on the forehead and back, patchy alopecia and generalized ichthyosis. Histology of the forehead and back showed a dense, lymphocytic, folliculocentric and perivascular infiltrate of predominantly CD4-positive T cells consistent with folliculotropic MF. Histological examination of biopsies from ichthyotic skin found similar features. Our patient had a histological diagnosis at the age of 15 years, making him the youngest reported patient with either folliculotropic MF or ichthyotic MF.

    Chronic urticaria is characterized by transient, pruritic lesions of varying sizes, with central pallor and well-defined edges, with disease duration longer than six weeks. Its cellular infiltrate consists of neutrophils, lymphocytes and eosinophils. There is a subgroup of patients with eosinophilic or neutrophilic urticaria, resistant to the treatment with antihistamines, but that respond to a combination of antihistamine with other drugs. To evaluate the present infiltration in chronic urticaria biopsies and correlate it with the clinical disease activity and response to treatment. Forty-one patients with chronic urticaria were classified according to the score of severity of the disease, response to treatment and type of perivascular infiltrate. Inflammatory infiltrates were divided in eosinophilic (46.30%), neutrophilic and mixed. An association was found between the eosinophilic infiltrate and clinical scores of greater severity (p = 0.002). This association shows that the eosinophilic inflammatory infiltrates denote high clinical activity, which means more severe and exuberant clinical pictures of the disease.

    Adult onset Still's disease (AOSD) is a systemic auto-inflammatory condition of unknown etiology, characterized by high fever, an evanescent, salmon-pink maculopapular skin rash, arthralgia or arthritis and leukocytosis. AOSD can also present with atypical cutaneous manifestations, such as persistent pruritic coalescent papules or plaques and linear lesions that have highly distinctive pathological features and are usually associated with severe disease. Herein, we present a 31-year-old Brazilian man with both typical Still's rash and atypical persistent polymorphic cutaneous manifestations associated with severe systemic inflammatory response syndrome. Eosinophils that are consistently lacking in the AOSD-associated skin lesions were evident in the skin biopsy of the persistent atypical cutaneous manifestations and were either drug-related or AOSD-associated.

    Chagas disease (CD) is an endemic anthropozoonosis from Latin America of which the main means of transmission is the contact of skin lesions or mucosa with the feces of triatomine bugs infected by Trypanosoma cruzi. In this article, we describe the first acute CD case acquired by vector transmission in the Rio de Janeiro State and confirmed by parasitological, serological and PCR tests. The patient presented acute cardiomyopathy and pericardial effusion without cardiac tamponade. Together with fever and malaise, a 3 cm wide erythematous, non-pruritic, papule compatible with a "chagoma" was found on his left wrist. This case report draws attention to the possible transmission of CD by non-domiciled native vectors in non-endemic areas. Therefore, acute CD should be included in the diagnostic workout of febrile diseases and acute myopericarditis in Rio de Janeiro.

    Horses develop many skin and respiratory disorders that have been attributed to allergy. These disorders include pruritic skin diseases, recurrent urticaria, allergic rhinoconjunctivitis, and reactive airway disease. Allergen-specific IgE has been detected in these horses, and allergen-specific immunotherapy is used to ameliorate clinical signs. The best understood atopic disease in horses is insect hypersensitivity, but the goal of effective treatment with allergen-specific immunotherapy remains elusive. In this review, updates in pathogenesis of allergic states and a brief mention of the new data on what is known in humans and dogs and how that relates to equine allergic disorders are discussed.

    Full Text Available Toxic epidermal necrolysis (TEN is a drug-related fatal disease. Extensive necrosis of the epidermis can lead to serious complications. This report describes two cases of TEN, associated with deflazacort (DFZ, in two boys, aged 4 years and 14 years, with nephrotic syndrome (NS. The 14-year-old male teenager received DFZ following NS relapse. After 17 days, pruritic papules appeared on the lower extremities. Another case involved a 4-year-old boy receiving DFZ and enalapril. After a 41-day DFZ treatment period, erythematous papules appeared on the palms and soles. Within 3 days, both boys developed widespread skin lesions (>50% and were admitted to the intensive care unit for resuscitative and supportive treatment. The patients showed improvement after intravenous immunoglobulin-G therapy. Owing to the rapid, fatal course of TEN, clinicians need to be aware of the adverse effects of this drug when treating cases of NS.

    2015-01-01

    Lichenoid dermatoses, a group of inflammatory skin conditions with characteristic clinical and histopathologic findings, range from common to rare. Classic lichen planus typically presents as pruritic, polygonal, violaceous flat-topped papules and plaques; many variants in morphology and location also exist. Other lichenoid dermatoses share similar clinical presentations and histopathologic findings. These include lichenoid drug eruption, lichen planus-like keratosis, lichen striatus, lichen nitidus, and keratosis lichenoides chronica. Epidemiologic characteristics vary among each lichenoid disorder. While classic lichen planus is considered a disease of adults, other lichenoid dermatoses may be more common in younger populations. The literature contains an array of reports on the variations in presentation and successful management of lichen planus and lichenoid dermatoses among diverse populations. Familiarity with the characteristics of each lichenoid dermatosis, rare or common within each patient population, is key to accomplishing timely recognition and effective management.

    Psoriasis is a prevalent chronic inflammatory disease whose exact aetiology is not fully understood, but both genetic and environmental factors have been implicated in the onset and progression of the disease. At the skin level, psoriasis is characterized by localized or widespread thick raised...... silvery-white scaling and pruritic plaques and studies have shown that psoriasis negatively affects patients' quality of life, and depression occurs more often in patients with psoriasis. However, data have shown that psoriasis is a systemic disease which affects the joints, vasculature, and other tissues...... as well. Indeed, approximately one-third of patients with psoriasis develop psoriatic arthritis, and patients with severe psoriasis have a shortened life expectancy. Although our knowledge of the pathogenesis of psoriasis has advanced significantly in the past decade, as have the pharmacological treatment...

    Haemorrhoids or piles are varicosities in the anal canal caused by local pressure. Sometimes they prolapse. Symptoms may include itching, discomfort, pain and bleeding. Haemorrhoids are common in pregnancy. Constipation aggravates piles, so a healthy diet with plenty of water and fibre is advisable. Some sufferers need an appropriate laxative as well. Cleanliness of the anal area is important. Proprietary moist toilet tissues are sold for this purpose and can be soothing and helpful. Relief of symptoms is by haemorrhoid creams, ointments and suppositories. Active ingredients typically include antiseptics, anti-inflammatories, anti-pruritics and local anaesthetics. Many are available from pharmacies without a prescription. If in doubt, always refer the patient to a doctor. For example, rectal bleeding may be due to some more serious condition, or pruritus to anal thrush. In the case of children the advice of a doctor should be sought.

    There is increasing awareness of reactions to vaccination that include persistent skin reactions. We present here a retrospective investigation of long-lasting skin reactions and aluminium hypersensitivity in children, based on medical records and questionnaires sent to the parents. In the 10-year period 2003 to 2013 we identified 47 children with persistent skin reactions caused by childhood vaccinations. Most patients had a typical presentation of persisting pruritic subcutaneous nodules. Five children had a complex diagnostic process involving paediatricians, orthopaedics and plastic surgeons. Two patients had skin biopsies performed from their skin lesions, and 2 patients had the nodules surgically removed. Forty-two children had a patch-test performed with 2% aluminium chloride hexahydrate in petrolatum and 39 of them (92%) had a positive reaction. The persistent skin reactions were treated with potent topical corticosteroids and disappeared slowly. Although we advised families to continue vaccination of their children, one-third of parents omitted or postponed further vaccinations.

  19. Allergy, Histamine and Antihistamines.

    Church, Martin K

    2017-01-01

    This chapter concentrates on the role in allergic disease of histamine acting on H 1 -receptors. It is clear that allergy has its roots in the primary parasite rejection response in which mast cell-derived histamine creates an immediate hostile environment and eosinophils are recruited for killing. This pattern is seen in allergic rhinitis where the early events of mucus production and nasal itching are primarily histamine mediated whereas nasal blockage is secondary to eosinophil infiltration and activation. In asthma, the role of histamine is less clear. Urticaria is characterized by mast cell driven pruritic wheal and flare-type skin reactions that usually persist for less than 24 h. Although the events leading to mast cell degranulation have been unclear for many years, it is now becoming evident that urticaria has an autoimmune basis. Finally, the properties of first- and second-generation H 1 -antihistamines and their role in allergic is discussed.

    Full Text Available The incidence of some skin diseases are increasing at adolescent and early adulthood period. The most frequent disease at this period is acne vulgaris whereas fungal diseases, dermatitis, dermatosis which are due to stress and other reasons, oral mucosal lesions and herpetic lesions of perioral region are also frequent. In this research we aim to determine the frequent dermatologic diseases of university students and 147 female, 74 male, a total of 221 students are included. We questioned the dermatologic complaints of students, then examined dermatologically in detail and registered ages, sexes, findings of the dermatological examination and dermatological diagnostic informations. As a result it is found out that the most frequent diseases are acne vulgaris (34.1%, allergic and pruritic dermatosis (16.6%, fungal diseases ( 13.0%, and eritamatous-squamous disease (8.3%.

    2007-01-01

    Full Text Available Bullae occurring in lesions of morphea are uncommon. The cause of bullae formation in morphea is multifactorial, although lymphatic obstruction from the sclerodermatous process is considered the likeliest cause. Bullous morphea may be confused clinically with lichen sclerosus et atrophicus since both diseases may cause bullae in sclerodermatous plaques. A 69-year-old woman presented with a history of generalized morphea diagnosed 9 years earlier; and a 1-month history of pruritic bullae on her inframammary folds, axillary regions, lower abdomen, upper extremities and inguinal folds. Physical examination revealed multiple erythematous erosions, hemorrhagic vesicles and eroded bullae with slight scale or crusts overlying hypopigmented, indurated, shiny plaques. Skin biopsy revealed prominent edema in the papillary dermis, resulting in bulla formation and thickening of collagen fibers within the dermis. Direct immunofluorescence was negative. According to histologic and clinical features, the diagnosis of bullous morphea was established.

    Full Text Available Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE has been described in a 54-year-old female. The patient presented with pruritic erythematous papules on the left frontoparietal scalp. Histopathological examination showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophils. Features of follicular mucinosis were observed in the same section with several hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these two distinct histopathological patterns in the same biopsy specimen has been described in only three cases to date.

    Scabies is a pruritic dermatosis caused by the ectoparasite Sarcoptes scabiei var. hominis. The diagnosis of scabies is usually made on clinical grounds, but histopathological and/or dermoscopic examinations may sometimes be of assistance. However, these diagnostic modalities do not offer a detailed in vivo demonstration of the motile microorganism. Reflectance confocal microscopy (RCM) is a relatively novel imaging modality that permits in vivo examination of the skin at a resolution similar to that used during similar to histopathologic resolution. Here, a patient with crusted scabies is presented in whom a brief section of the lifecycle of S. scabiei was captured by RCM. Using this advanced imaging modality, the ectoparasite's motion within the human host can be examined for clinical or research purposes and the mite's viability may be assessed to monitor the response to treatment.

    Full Text Available Scabies is an infestation caused by Sarcoptes scabiei and characterised by polymorphous lesions that may include burrows, papules, pustules, crusts and excoriations. Several pruritic diseases may be confused with scabies. Herein, we present a case of scabies with lesions resembling perforating folliculitis diagnosed on the basis of both clinical and histopathological view. A 72-year-old man with type 2 diabetes mellitus and receiving hemodialysis for ten years due to end-stage renal disease was admitted to our dermatology department with a 6-month history of severe pruritus. Based on the results of skin biopsy revealing Sarcoptes scabiei in the epidermis, the patient was diagnosed as scabies and was successfully treated with 5% permethrin. This case is presented to emphasize that scabies should be considered in the differential diagnosis in cases of chronic pruritus.

    Scabies is a common contagious cutaneous disease and usually affects the young, characterized by polymorphous lesions that may present as burrows, pruritic papules, and inflammatory nodules. Bullous scabies (BS) is its rather rare subtype, mimicking bullous pemphigoid. We report a 15-year-old Chinese boy presenting with 1-month history of pruritic bullae on his penile skin, showing poor response to both topical steroids and systemic antihistamines, but cured by sulfur ointment alone. No recurrence occurred in the 5 years of follow-up. We also reviewed the published cases. Up to date, 44 cases, including the present, have been reported. Of them, 30 were male and 14 were female. The age range was from 1 to 89 years old, with a median age of 70.6 years. The bullous lesions may involve the arms, legs, trunk, genitals, feet, buttocks, thighs, neck, inguinal folds, and may even be generalized. Trunk and extremities are the most common involved locations. Facial or mucosa involvement had never been reported. The histological findings present as a subepidermal split with variable inflammatory infiltrate predominantly neutrophils, and eosinophilic spongiosis, or both. Eighteen of 32 patients showed positive deposition of linear-granular IgG or complement 3 alone or in various combinations, and five of 24 patients revealed circulating IgG. All the 40 cases with therapeutic details were cured by antiscabietic remedy. BS always involves the trunk and extremities. It has a predilection for elderlies and males. The treatments for BS are similar to those of classical scabies. © The American Society of Tropical Medicine and Hygiene.

    Determining the cause of pruritus relies on establishing the pattern of abnormal pruritus. The presence of gastrointestinal (GI) disease has also been helpful in determining the cause of pruritus. No study has systematically evaluated typical GI signs and pruritic behaviours in apparently healthy dogs. To evaluate owners' perceptions of pruritus and GI signs in apparently healthy dogs, and determine if age, breed, activity, diet or supplements affected these signs. Three hundred and fourteen apparently healthy dogs ≥ 12 months old with an unremarkable physical examination and no history of pruritus, otitis, skin/hair disease, metabolic or GI disease were enrolled. Thirty one veterinarians enrolled dogs after establishing their pruritus visual analog scale (PVAS) score and faecal consistency score (FCS); owners completed a comprehensive online survey regarding GI signs, possible pruritic behaviours, ear cleaning and sneezing. A PVAS score of ≤ 1.9 was recorded in 87.6% of dogs and the FCS was 2-3 in 94.9% of dogs. PVAS was positively correlated with paw licking/chewing, facial/muzzle rubbing, head shaking and sneezing. Scooting was positively correlated with sneezing. Over 96% of dogs had 1-3 bowel movements (BM) per day. Age was positively correlated with facial/muzzle rubbing, sneezing, coprophagia and borborygmi. The number of walks/day was positively correlated with paw licking/chewing, head shaking, sneezing, number of BM/day, coprophagia, belching, flatulence and borborygmi. A standard method of asking relevant questions was developed and the frequency of GI signs and many behaviours that may indicate pruritus in apparently healthy dogs was established. © 2015 ESVD and ACVD.

    Aquagenic urticaria is a rare but well-known form of physical urticaria mainly affecting young women. It is characterised by the appearance of erythematous and pruritic plaques a few minutes after initial contact with water and irrespective of temperature. The physiopathology of this condition remains poorly understood. Herein, we report a case of localised aquagenic urticaria occurring solely on contact with seawater. A 32-year-old woman reported onset of erythematous and pruritic plaques, confined to the neck and lower part of the face, several minutes after the start of bathing in seawater. Skin tests were carried out by applying wet compresses soaked in seawater (37°C for 30 min) to the areas in which the skin reaction usually occurred. A control test using a compress soaked in fresh water was carried out under identical conditions. An urticaria reaction was noted in the areas in contact with seawater, but no reaction was seen in the areas coming into contact with fresh water. Antihistamines taken on the days of bathing proved ineffective. A number of similar cases have been reported in the literature, enabling the characterisation of this particular form of aquagenic urticaria and allowing its principal characteristics to be defined. It appears to be dependent solely on the salt content of the water. It is reported by young women while bathing in seawater. The urticaria plaques show a predilection for the neck and lower part of the face, as in our case, as well as the shoulders on occasion. The efficacy of antihistamines is inconsistent. The prevalence of this as yet poorly known entity is doubtless underreported. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  8. ECTOPIC CUTANEOUS SCHISTOSOMIASIS: REPORT OF TWO CASES AND A REVIEW OF THE LITERATURE

    Directory of Open Access Journals (Sweden)

    1998-07-01

    Full Text Available Two cases of ectopic cutaneous schistosomiasis are described. Both patients presented with abdominal papular skin lesions, which on biopsy were found to contain granulomas with Schistosoma mansoni eggs. Twenty-five other cases were retrieved from the literature. Most patients were female, mean age 24.9 year, with a predominance of the white race. The most common localization was anterior thorax and abdomen. Usually, the lesions were asymptomatic. In few cases, however, severe clinical syndromes due to the parasite coexisted, such as transverse myelitis or the acute-toxemic form of the disease. Intestinal infection was not frequently demonstrated in these patients. The importance of the recognition of these cutaneous lesions may rest on the opportunity to provide an etiological diagnosis in these difficult cases.Dois casos de esquistossomose cutânea ectópica são relatados. Ambos os pacientes apresentavam lesões papulares no abdômen que, ao exame histopatológico, mostraram presença de granulomas contendo ovos de Schistosoma mansoni. Vinte e cinco casos de esquistossomose cutânea ectópica foram encontrados descritos na literatura. A maioria dos pacientes era do sexo feminino, com idade média de 24,9 anos e predominância da raça branca. A localização mais comum foi o tórax anterior e abdômen. Freqüentemente, as lesões eram assintomáticas. Em alguns casos, no entanto, coexistiam alterações sistêmicas graves, relacionadas ao parasito, como mielite transversa e a forma aguda toxêmica da doença. Na maior parte dos casos, a infecção intestinal não pôde ser demonstrada. O reconhecimento destas lesões cutâneas pode ser importante por proporcionar oportunidade para um diagnostico etiológico nestes casos.

    Cutaneous leishmaniasis caused by Leishmania tropica can leave troublesome and unsightly lesions. Treatment of these scars remains difficult. Pulsed-dye laser (PDL) is one therapeutic approach that may improve the clinical appearance of erythematosus lesions. The purpose of this retrospective study was to evaluate the effectiveness of PDL on the residual red lesions of erythematous facial leishmaniasis in three patients. Case no. 1: a 14-year-old girl presented an ulcerative and erythematous nodular lesion on her left cheek. One month after treatment, an erythematous lesion measuring 3 cm persisted on the patient's cheek, without atrophy or hyperpigmentation. PDL 595nm was used at the following settings: duration: 3ms; spot size: 7mm; energy: 8 j/cm(2). Case no. 2: a 43-year-old woman presented an erythematous papular lesion on her right cheek. Following treatment, a 4-cm hypertrophic, red telangiectasic lesion remained. PDL 595nm was used with the following settings: pulse duration: 3 ms; spot-size: 10mm; energy: 8 j/cm(2). Case no. 3: a 60-year-old woman presented an erythematous papular lesion on her cheek. After treatment, an infiltrated erythematous macule with surface telangiectasia measuring 3.5cm remained. PDL 595nm was also given using the following settings: pulse duration: 3 ms; spot size: 10mm; energy: 8 j/cm(2). All three patients underwent three sessions of PDL. The erythematous and telangiectasic lesions showed improvement after the initial session and had completely disappeared after the third session. Post-laser purpura subsided within around 10 days. Therapeutic response was assessed clinically by comparing photographs taken before and after treatment and follow-up lasted 12 months. Cutaneous leishmaniasis caused by L. tropica is endemo-epidemic in Morocco. A number of treatments are available for red residual lesions but thanks to its effect on erythematous and vascular lesions, PDL has been shown to provide the most reproducibly

    Cutaneous lesions caused by the pine processionary caterpillar Thaumetopoea pityocampa (TP) are frequent in pinewood areas. In the present study, 30 patients diagnosed with occupational immunologic urticaria from this caterpillar were included. Immediate hypersensitivity was demonstrated by performing prick and IgE-immunoblotting tests. Workers were grouped according to their common tasks. Occupations at risk of exposure to TP were pine-cone collectors/woodcutters (14), farmers/stockbreeders (8), other forestry personnel (4), construction workers (2), residential gardeners (1) and entomologists (1). Besides contact urticaria, angioedema (60%), papular lesions of several days of evolution (30%) and anaphylactic reactions (40%) were also detected. The most frequently detected molecular weight bands by immunoblot were 15 (70%), 17 (57%) and 13 kDa (50%). The appearance of isolated bands corresponds with the least serious cases. Only 8 subjects had bands higher than 33 kDa, which was present in the 3 most severe cases of anaphylactic reactions. By presenting these cases, we wish to offer the largest series reported so far of occupational immunologic contact urticaria caused by TP. We include the first cases described in certain occupations, some of them not directly related to forestry work. Pine-cone or resin collectors, woodcutters, farmers and stockbreeders were the most frequently and severely affected workers.

    Scabies is a contagious infestation transmitted by skin-to-skin contact and sometimes by contact with contaminated material. The scabies mite burrows into the skin, producing a papular rash and severe itch at typical sites of predilection. We systematically reviewed the literature to compare the efficacy of various anti-scabies agents, including a calculation of relative risks and confidence intervals. A literature search yielded 596 initial hits; after screening in accor-dance with the defined inclusion and exclusion criteria, 16 studies were selected for this review. Among topical treatments for scabies, permethrin was equally effective or more effective than crotamiton or benzyl benzoate. In a comparison of topical versus systemic treatment, topical permethrin and systemic ivermectin did not differ substantially in efficacy (7 comparative studies revealed no difference; one revealed a difference in favor of permethrin). Comparative trials of topical benzyl benzoate versus systemic ivermectin yielded inconsistent findings. Single and double administrations of ivermectin were similarly effective. In trials involving entire populations with a high prevalence of scabies, systemic ivermectin was found to be superior to topical permethrin. There are hardly any differences in efficacy between the available treatments for scabies. Single administrations of permethrin 5%, crotamiton 10%, and systemic ivermectin are all comparably effective. There are differences in the frequeny and ease of application as well as when eradicating scabies in populations with a high prevalence.

    Scabies is a common, yet neglected, skin disease. Scabies occurs across Australia, but most frequently in socioeconomically disadvantaged populations in tropical regions, including in remote Aboriginal and Torres Strait Islander communities. In temperate settings, the disease clusters in institutional care facilities. The objective of this article is to provide updates on the clinical diagnosis and treatment approaches for scabies in Australia. Clinical examination remains the mainstay of diagnosis, although dermatoscopy is a useful adjunct. Scabies presents with severe itch and a papular rash, with a predilection for the hands, feet and genitalia. The distribution may be more widespread in infants and older people. Secondary bacterial infection is also common in patients with scabies. Crusted scabies is a rare but highly infectious variant. Topical permethrin is highly effective for individual treatment, but less practical for treatment of asymptomatic contacts and control of outbreaks. Oral ivermectin is a safe and effective alternative, and is now listed on the Pharmaceutical Benefits Scheme as a third-line treatment.

    Lobomycosis is a chronic skin mycosis endemic in Amazon regions characterized by chronic nodular or keloidal lesions caused by Lacazia loboi , an uncultivable fungus. Imported cases in nonendemic countries are rare and diagnosed after years. We describe a case of lobomycosis in a healthy 55-year-old Italian traveler who had acquired the infection during 5-day-honeymoon in the Amazon region of Venezuela in 1999. Several weeks after return, he recalled pruritus and papular skin lesions on the left lower limb, subsequently evolving to a plaque-like lesion. Blastomycosis and cryptococcosis were hypothesized based on microscopic morphology of yeast-like bodies found in three consecutive biopsies, although fungal cultures were always negative. In 2016, exfoliative cytology and a biopsy specimen examination showed round yeast-like organisms (6-12 μm), isolated or in a chain, connected by short tubular projections fulfilling the morphologic diagnostic criteria of Lacazia spp. The microscopic diagnosis was confirmed by molecular identification.

    Viruses are considered intracellular obligates with a nucleic acid RNA or DNA. They have the ability to encode proteins involved in viral replication and production of the protective coat within the host cells but require host cell ribosomes and mitochondria for translation. The members of the families Herpesviridae, Poxviridae, Papovaviridae, and Picornaviridae are the most commonly known agents for cutaneous viral diseases, but other virus families, such as Adenoviridae, Togaviridae, Parvoviridae, Paramyxoviridae, Flaviviridae, and Hepadnaviridae, can also infect the skin. Herpetic whitlow should be considered under the title of special viral infections of the acral region, where surgical incision is not recommended; along with verruca plantaris with its resistance to treatment and the search for a new group of treatments, including human papillomavirus vaccines; HIV with maculopapular eruptions and palmoplantar desquamation; orf and milker's nodule with its nodular lesions; papular-purpuric gloves and socks syndrome with its typical clinical presentation; necrolytic acral erythema with its relationship with zinc; and hand, foot, and mouth disease with its characteristics of causing infection with its strains, with high risk for complication.

    Full Text Available Human immunodeficiency virus type 1- infected patients with syphilis are among the most important transmitters of HIV-1 infection due to biological effects of genital ulcerations, and aggravation due to their continued risky behavior. The association between primary syphilis and acute HIV-1 co-infection is not well documented, and reports on isolated cases are raising special interest and indicate that this double primary co-infection may occur. We present a case of a 31-year-old man with no past medical history who presented with fever, papular rash on the face which lasted for a few days, and a single genital ulcer. He was diagnosed with primary syphilis and primary HIV-1 infection after a single exposure with an infected female sex worker. Male-to-female HIV transmission during vaginal intercourse is significantly more likely than female-to-male HIV transmission. However, high prevalence of sexually transmitted diseases among female sex workers contributed to high HIV transmission probability, as in our case.

    Head lice are transmitted by head to head contact. Optimal therapy includes malathion lotion 0.5% repeated in one week left on for 30 minutes to 8 hours. Spinosad topical suspension 0.9% repeated in one week left on for 10 minutes is another option. Scabies is transmitted mainly by direct contact but also via heavily infested fomites due to crusted scabies. Permethrin 5% cream to the body repeated in four days is often sufficient; however, scalp treatment with malathion lotion 0.5% is helpful in crusted scabies and in infested children. Oral ivermectin 200 mcg/kg is another option, repeated in four days. For scabies more than lice, fomites should be placed in a drier at 60 °C for 10 minutes to kill the arthropods. Treatment of close contacts in both cases will control outbreaks and repeated infestations. Both have been associated with methicillin-resistant Staphylococcus aureus infection. Bed bugs are a common cause for papular urticaria. Identification of the insect in the mattress or bedding confirms the diagnosis. Prevention involves encasing the mattress in a sealed plastic cover and extermination. Delusions of parasitosis is a diagnosis of exclusion that is best treated with an antipsychotic. © 2012 The International Society of Dermatology.

    Cutaneous lesions in human patient due to the bite of rat mite Ornithonyssus bacoti are frequently misdiagnosed as allergies, fungal infection, or bacterial infection. Bite lesions in the personnel working in a Laboratory Animal facility which was infested with O. bacoti is reported here along with its therapeutic management. Diagnosis of the parasites obtained from the clothing of the personnel and later from the infested mice colony was based on preliminary light microscopy and confirmed by scanning electron microscopy. The mean length and breadth of adult female mite were 1.13 mm × 0.63 mm. The body is hairy, unsegmented and has four pairs of legs. The gnathostoma has long pointed chelicerae and pedipalp. The dorsal surface has one dorsal shield, and the ventral surface has three shields- sternal, genital and anal shield. Treatment of dermatitis involved antihistaminic drugs for a period of 3-5 days. The skin lesion, characterized by papular erythema, tends to disappear within a period of 4-5 days of antihistaminic treatment. In untreated cases, the lesions disappeared within 7-10 days. Tropical rat mite O. bacoti Hirst, 1931 was identified to be the cause of infestation in the laboratory mice colony of Pasteur Institute of India, Coonoor, Tamil Nadu, predisposing the animal handlers to be temporary host.

    Temporary henna tattoos or pseudotattoos have become increasingly widespread among children and adolescent. A generalized skin reaction, type erythema multiforme-like reaction is unusual, and rarely reported. We describe the case of a 7-year-old boy who reported erythematous papular bull's-eye shaped lesions and consolidated edema primarily in the upper and lower extremities. These lesions were compatibles with erythema multiforme-like reaction. He also showed an erythematous-eczematous lesion on his leg, shaped like a dolphin. In this area, a temporary henna tattoo was painted 1-month earlier. Patch test was positive for paraphenylenediamine (PPD). Skin reactions due to henna are rare. Most of the reactions are due to additives, especially PPD, an aniline derivative, which is added to speed up the process of skin dyeing and to give a darker brown to black color ("black" henna). As henna tattoos are becoming increasingly popular, prevention requires the annual provision of information to consumers, especially young people and their parents.

    Serratia marcescens is an unusual cause of severe skin infection initially described in immunocompromised patients. We report a case of necrotizing cellulitis of the leg caused by S marcescens in a 68-year-old woman with diabetes mellitus and a history of chronic lymphoedema of the leg. We reviewed the literature and found 49 cases of severe skin infections from S marcescens that included 20 cases of necrotizing fasciitis (NF) as well as 29 cases of severe skin infections without NF (non-NF cases). Patients were immunocompromised in 59% to 70% of cases. The mortality rate was high in NF cases (60%) versus non-NF cases (3%). Surgery was required in 95% of NF cases and in 24% of non-NF cases. The other clinical manifestations of S marcescens skin infection reported in the literature included disseminated papular eruptions in patients infected with human immunodeficiency virus with folliculitis on the trunk. Serratia marcescens is naturally resistant to amoxicillin alone and amoxicillin associated with clavulanic acid. Broad-spectrum antibiotics are indicated to treat S marcescens skin infections, and surgery should be promptly considered in cases of severe skin infections if appropriate antibiotic therapy does not lead to rapid improvement.

    Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease that occurs more frequently in middle-aged and elderly female patients. Previous studies indicate that OLP is a T-cell dysfunction-induced localized autoimmune disease. Clinically, six types of OLP, namely reticular, papular, plaque-like, atrophic/erosive, ulcerative, and bullous types, can be identified. OLP more commonly affects buccal mucosa, tongue, and gingiva. It always has a bilateral and symmetric distribution of the oral lesions. Plaque-like and atrophic/erosive OLP may be misdiagnosed as oral leukoplakia and oral erythroleukoplakia, respectively. Our previous study found serum autoantibodies in 195 (60.9%) of the 320 OLP patients. Specific serum anti-nuclear, anti-smooth muscle, anti-mitochondrial, gastric parietal cell, thyroglobulin, and thyroid microsomal autoantibodies are present in 28.1%, 8.4%, 1.6%, 26.3%, 21.3%, and 24.4% of 320 OLP patients, respectively. Furthermore, we also discovered that 21.9%, 13.6%, 7.1%, 0.3%, and 14.8% of 352 OLP patients have hemoglobin, iron, vitamin B12, and folic acid deficiencies, and abnormally high serum homocysteine level, respectively. Therefore, it is very important to examine the serum autoantibody, hematinic and homocysteine levels in OLP patients before starting the treatments for OLP patients. Because OLP is an immunologically-mediated disease, corticosteroids are the drugs of choice for treatment of OLP. Copyright © 2018. Published by Elsevier B.V.

    Full Text Available A 12-month-old healthy girl presented with a chronic diaper rash. Physical examination demonstrated crusting of the scalp, erythematous papules with surrounding petechiae on the lower abdomen, and an intraoral palatal ulcer. Further imaging demonstrated bone involvement. Histopathologic examination of involved skin and the intraoral ulcer demonstrated epithelioid histiocytes with “coffee bean-shaped” nuclei, staining positive for CD1a and langerin by immunohistochemistry, consistent with Langerhans cell histiocytosis (LCH. LCH is a disease entity of unknown etiology characterized by histiocytic proliferation that most commonly presents in young children. The cutaneous findings of LCH include a seborrheic dermatitis-like and/or red-brown papular eruption. Intraoral examination is crucial as oral mucosal and maxillofacial skeletal disease can also be seen in LCH. When a child presents with a recalcitrant seborrheic dermatitis-like eruption or chronic diaper rash, the clinician should be alerted to the possibility of LCH. Timely recognition and diagnosis of LCH is important for oncologic referral, evaluation, and treatment.

    To investigate clinical, pathological and mycological findings in canaries, in which pox lesions and Aspergillus fumigatus (A. fumigatus) infection were observed simultaneously. This study was performed on a breeding colony (about 100 canaries) affected by fatal wasting disease. Necropsy was undertaken on 10 severely affected canaries, and gross lesions were recorded. Samples from internal organs displaying lesions were obtained for histopathological evaluation. Tracheal swap samples of internal organs of the all infected animals with lesions at necropsy were cultured in Sabouraud Dextrose Agar for mycological examination. At necropsy, caseous foci were determined in the lungs, on the air sacs, liver, spleen, heart. Swelling of the eyelids, diffuse hemorrhages in the subcutaneous tissue with small papular lesions of the skin were other typical necropsy findings. Histopathologically, pathognomonic eosinophilic intracytoplasmic inclusion bodies, which called Bollinger bodies, in both skin cells and vacuolated air way epithelial cells confirmed canary pox infection. Moreover, histopathological examination of the white-yellowish caseous foci revealed necrotic granulomatous reaction consisting of macrophages, heterophil leukocytes and giant cells encapsulated with a fibrous tissue. After the culture of the tissue samples, the formation of bluish green colonies confirmed A. fumigatus infection. Canary pox has been known as the disease that can result in high losses in a short time, as a re-emerging disease that has not been present during recent years in canary flocks in Iran. So, the current paper provides useful information to prevent misdiagnosed of canary pox disease which can cause secondary mycotic infection.

    Full Text Available Abstract Introduction Birt-Hogg-Dubé syndrome is a rare genodermatosis characterized by hair follicle hamartomas, renal tumors and spontaneous pneumothorax. We present the case of a patient with pulmonary cysts and recurrent spontaneous pneumothorax. She had typical skin lesions, and was found to have a hybrid oncocytoma which was surgically excised. Case presentation A 60-year-old Caucasian woman had a 10-year history of cystic lung disease and recurrent spontaneous pneumothoraces. She was noted to have papular lesions over her face and forehead. The result of a biopsy showed these lesions to be fibrofolliculomas. A diagnosis of Birt-Hogg-Dubé syndrome was made and she was screened for renal tumors since these are a recognized association. A hybrid oncocytoma was detected which was surgically excised by partial nephrectomy. Conclusion It is important to consider a possible diagnosis of Birt-Hogg-Dubé syndrome in cases of recurrent pneumothorax. Affected individuals must be screened for renal tumors, a potentially lethal consequence of this syndrome.

    Tuberculosis of the penis is an extremely rare disease with few cases reported in the literature. We present the case of a 64 year-old man with a whitish papular-ampullary eruption in the glans penis. After antibiotic/antimycotic therapy and several topical ointments for 3 months without response he was referred to our Department. Biopsy of the ulceration edge was performed and pathology result showed a chronic granulomatous inflammatory necrotizing lesion with granulomatous vasculitis lesions, without tumor infiltration. Systemic examination to rule out other tuberculosis foci was negative. With de suspicion of primary tuberculosis of the glans penis, anti tuberculosis therapy with Isoniazid and Piridoxine was started. Within a period of five months the ulceration healed significantly. Currently, the patient is still asymptomatic without glans penis lesions. Primary glans penis tuberculosis is a rare disease, but we must consider it (both primary and secondary forms) to try to avoid diagnostic delays that may cause prejudice for the patient. This condition promptly responds to anti tuberculosis therapy as evidenced by our case and many other reports.

    Full Text Available Primary cutaneous plasmacytosis is a rare cutaneous disorder with extensive cutaneous plaques/papules mainly on the trunk and face. Cases have mostly been documented from Japan. We present here a rare case of cutaneous plasmacytosis from India of Mongolian descent. This 50-year-old female from Mizoram had extensive maculo-papular violaceous plaques distributed on the face, axillae, trunk and lower extremities. Initial and repeat skin biopsy revealed dense perivascular and periadnexal mature plasma cells. She also had lymphadenopathy. Serum protein electrophoresis did not reveal any M band and the Bence Jones protein was negative in urine. The patient had multiple superficial lymph nodes and a biopsy from the cervical lymph node showed effacement of normal nodal architecture by sheets of plasma cells. Immuno histochemistry was done from both skin and lymph node biopsies. The kappa and lambda tight chains were not restricted; there by proving the polyclonal nature of the plasma cells. The novelty of the case lies in its classical clinical presentation with histopathological documentation.

    Benzoyl peroxide was introduced as a basic treatment already in acne therapy 1934. The mechanism of action is the reduction of anaerobe bacteria by strong oxidation processes. No resistancies have been ever reported. BPO is available in 2.5, 5 and 10 % formulations. Its efficacy is slightly related to the strength of concentrations, but the side effect profile with burning, erythema and desquamation is increasing with concentrations. BPO 5% mostly is efficient enough to control acne of grades I to II according to the Kligman & Plewig classification. BPO my bleach clothes and hair. It is the most costeffective topical drug in acne of grades I-II. Inflammatory acne of the papular-pustular type I-II can also be treated by topical antibiotics such as erythromycin, clindamycin, and, less frequent and today not anymore recommended tetracyclines. Mechanism of action is not alone an antibacterial but anti inflammatory effect. The efficacy and penetration of the topical antibiotics between the groups are similar. Randomized studies have shown that concentrations of 2-4% are equivalent to oral tetracycline and minocycline in mild to moderate acne. Combinatory formulations with BPO and with retinoids enhance the efficacy significantly. Topical antibiotics plus BPO show less bacterial resistancies as topical antibiotics alone. Antibiotics should therefore not be used as monotherapy. Moreover gram negative folliculitis may develop. Azelaic acid is acting as an antimicrobial and can also reduce comedones. It can also be used in pregnancy and during the lactation period.

    Full Text Available A 13-year-old girl was admitted to our department with a history of severe pain of her left axilla and fever. On physical examination, a block of lymph nodes in her left axilla, diffuse papular rash, and red-violet swelling of her supraclavicular and subclavian region were noted. Imaging investigations revealed left axillar and supraclavicular lymphadenopathy and a small nodular shade in the upper lobe of her left lung. A biopsy from an axillary lymph node established the diagnosis of anaplastic large cell lymphoma (ALCL, whereas DNA of Mycobacterium tuberculosis was detected by polymerase chain reaction (PCR in the same tissue biopsy. Patient was started on chemotherapy for ALCL and achieved remission of all initially involved fields. Nevertheless, two new nodular lesions were detected in the left lower lobe. Biopsy revealed granulomas, and PCR was positive for M. tuberculosis. Our patient received treatment with the combination of isoniazid and rifampin (12 months, pyrazinamide (the first 2 months, and maintenance chemotherapy for her ALCL for one year simultaneously. Four years later, she is disease free for both mycobacterial infection and lymphoma. We are reporting this successful management of mycobacterial infection in a patient with ALCL despite intensive chemotherapy that the patient received at the same time.

  9. Hairless and the polyamine putrescine form a negative regulatory loop in the epidermis.

    Hairless (HR) is a nuclear protein with corepressor activity that is highly expressed in the skin and hair follicle. Mutations in Hairless lead to hair loss accompanied by the appearance of papules (atrichia with papular lesions), and similar phenotypes appear when the key polyamine enzymes ornithine decarboxylase (ODC) and spermidine/spermine N(1) -acetyltransferase (SSAT) are overexpressed. Both ODC and SSAT transgenic mice have elevated epidermal levels of putrescine, leading us to investigate the mechanistic link between putrescine and HR. We show here that HR and putrescine form a negative regulatory network, as epidermal ODC expression is elevated when HR is decreased and vice versa. We also show that the regulation of ODC by HR is dependent on the MYC superfamily of proteins, in particular MYC, MXI1 and MXD3. Furthermore, we found that elevated levels of putrescine lead to decreased HR expression, but that the SSAT-TG phenotype is distinct from that found when HR is mutated. Transcriptional microarray analysis of putrescine-treated primary human keratinocytes demonstrated differential regulation of genes involved in protein-protein interactions, nucleotide binding and transcription factor activity, suggesting that the putrescine-HR negative regulatory loop may have a large impact on epidermal homeostasis and hair follicle cycling. © 2013 John Wiley & Sons A/S.

    Like many other drugs co-trimoxazole can induce a large number of different skin reactions, mainly of allergic pathogenesis. The majority of these reactions, such as urticarial, purpuric, maculo-papular, and pustular exanthemas as well as photallergic reactions, generally do not endanger the life of the patient. Apart from very rare cases of anaphylactic shock, there is a risk of lethality associated with Stevens-Johnson syndrome and Lyell's syndrome of approximately 1% and 30%, respectively. Between 1981 and 1985, an extensive epidemiological survey was carried out in Germany which enabled approximation of drug induced severe skin reactions (Lyell's syndrome, Stevens-Johnson syndrome). Preliminary evaluation of the survey allowed the identification of 217 Lyell's syndromes and 296 Stevens-Johnson syndromes. The total registration rate resulting from an almost complete survey of all applicable medical units (dermatology, burns, intensive care) was 92%. The basic risk amongst the population of acquiring Lyell's syndrome and Stevens-Johnson syndrome, as calculated from the data gathered between 1981 and 1985, is 0.8 and 1.0 per year, and per one million inhabitants respectively, in the drug-related incidence calculation. Co-trimoxazole is in the upper third of the table of drugs which certainly, probably, or possibly induced a Lyell's syndrome and in the middle of the table of those that induced Stevens-Johnson syndrome.

    Urticaria is a common inflammatory skin disease. It is clinically defined as the occurrence of transient papular skin and/or mucosal lesions or subcutaneous lesions called angioedema. Chronic urticaria is defined as a clinical course over more than 6weeks. Different clinical forms of urticaria can coexist in the same patient. Urticaria results of mast cell activation. The diagnosis of urticaria is based on clinical examination. An allergic etiology for acute urticaria, although rare, is always to find and remove. Chronic urticaria is not allergic. Diagnosis is based on questioning and a careful clinical examination to rule out differential diagnoses. Few diagnostic tests are necessary for diagnosis and management, and are especially useful in case of doubtful diagnosis. The treatment of urticaria is symptomatic and based on anti-H1 second generation antihistamines as first-line therapy. In some chronic urticarial, antihistamines up dosing may be necessary. In the majority of patients, this treatment is sufficient to control chronic urticaria. In case of antihistamines failure, other treatment particularly immunomodulatory treatments can be offered in specialized departments.

    Pityriasis lichenoides is a benign inflammatory disease of unknown etiology. There are two types of this condition: an acute form (PLEVA = pityriasis lichenoides et varioliformis acuta) and a chronic one (PLC = pityriasis lichenoid chronica). Both are more common in children and young adults. To describe a case of PLC, discuss its clinical presentation, diagnosis, treatment and present a review of the literature. A seven-year-old child who presented with recurrent oligosymptomatic episodes of bright erythematous papular lesions in centripetal distribution, which subsided and left behind hypopigmented macules. The biopsy of the lesions confirmed chronic pityriasis lichenoid. During the 3 years of follow-up, multiple treatment regimens were used to reduce exacerbations, resulting in a partial response. PLC is a rare disease that represents a diagnostic and therapeutic challenge to the physician. The diagnosis of this condition is suspected clinically and confirmed by histology. It does not have specific treatment, but it responds well to corticosteroids, antibiotics, immunosuppressants and phototherapy with UVB narrowband (UVBnb). The latter has given the best results. It is important to monitor patients for risk of developing lymphoproliferative disorders. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Ten thousand new patients were seen between January 1971 and January 1975 at the Department of Pediatric Dermatology, "Hospital del Niño IMAN" in Mexico City. The patients were between 0 and 18 years old. They represented 10.4% of the entire pediatric population attending the general out-patient clinic of the hospital. The results of our study showed no significant difference among the sexes of patients. The highest proportion of patients in the sample were under one year of age. The most frequently observed groups of dermatoses were: parasitic, cutaneous reactions, viral and bacterial. The ten diseases most frequently observed were: papular urticaria (16.3%); atopic dermatitis (12.9%); scabies (10.4%); viral warts (8.4%); impetigo (6.8%); pitiriasis alba (6.6%); vitiligo (2.6%); acne (2.5%); dermatophytosis (2.4%) and numular eczema (2.3%). The 20 skin diseases most frequently recorded accounted for 85.8% of the sample. The ten most frequent skin diseases in each group of age were also recorded. The monthly and annual frequency for the more frequent dermatoses was studied. The present study provides epidemiological information for a rational development of programs on care, education and investigation in pediatric dermatology in Mexico.

    Full Text Available Fabry disease is a rare, X-linked disease, caused by the deficiency of lysosomal and #945;-galactosidase. Clinical fetaures are; acroparesthesia, unexplained fever, hypohidrosis and angiokeratomas. Untreated cases die early from cardiac complications, renal insuffiency or stroke. Currently there is no cure for Fabry disease, enzyme replacement therapy is the only choice in this progressive disease. A 9-year-old boy admitted to the Dermatology Clinic with reddish papular skin lesions, joint pain and anhydrosis. Hystological examination of the skin biopsy revealed angiokeratoma. There was no renal dysfunction or proteinuria. Biochemical confirmation of Fabry disease was made by determining the deficient leukocyte and #945;-galactosidase activity. Subsequently, the patient's molecular analysis was identified a novel nonsense mutation c. 785G>T in the GLA gene. Enzyme replacement therapy with agalsidase beta was started. He is on enzyme replacement therapy for 8 years, significant improvement was obtained in severity and frequency of pain crisis and fatigue. We report this case to emphasize the importance of early diagnosis of Fabry disease restricted to dermatological findings, especially before renal and cardiac involvement occurs, while enzyme replacement therapy is now available. Also this patient is one of the first Fabry patients under enzyme replacement therapy in Turkey. [Cukurova Med J 2015; 40(Suppl 1: 156-160

    Zoonotic cutaneous leishmaniasis (CL) is characterised by a major clinical polymorphism, especially the lupoid type. The aim of our study was to precise the anatomic and clinical particularities of this clinical form of CL. The present work was a prospective 1-year study. In all patients, the epidemiologic and clinical characteristics were identified, together with those regarding disease progression. Standard cutaneous biopsies were carried out for all study patients. The lupoid form was observed in 15% of the patients. It was clinically characterised by a lupoid aspect with papular and squamous placard surrounded by a satellite papule, a short duration of disease progression (28 months in average) and a preferential localisation at the level of the face and the elbow, statistically proven. At the histological level, epidermic hyperplasia was found in 93.8% of the cases; an inflammatory polymorphic dermic infiltrate consisting of lymphocytes and plasmocytes was found in all patients; granulomas were noted in 50% of the cases, and isolated epitheloid cells were observed in the derm of 3 patients. Amastigotes were rarely observed. In our series, the lupoid form was characterised with a short and non chronic evolution and two preferential sites for the affection: the face and the elbow. At the histological level, the lupoid type of CL appeared characterized by a high frequency of granuloma, usually organized, and rare amastigotes. However, the histology of authentic lupoid forms can be non granolomatosic.

    Complications from shoulder corticosteroid injections are uncommon. This article presents a case of altered color perception and visual disturbances in a 29-year-old male active duty Navy SEAL following an intra-articular glenohumeral corticosteroid injection, previously unreported in the orthopedic literature. The corticosteroid injection was administered for the treatment of right-shoulder stiffness occurring approximately 3 months following an arthroscopic superior labrum anterior-posterior (SLAP) repair and subacromial decompression of the ipsilateral shoulder. The patient experienced immediate relief after the injection. Seven days later, however, he began to notice visual disturbances with color and image distortion of his right eye. He also developed a papular, nonpruritic rash on his upper trunk that eventually extended down his legs. He was diagnosed by an ophthalmologist as having central serous chorioretinopathy, a condition in which serous fluid accumulates in the subretinal space of the eye, causing detachment of the retina from the underlying retinal pigment epithelium. The reaction spontaneously resolved within approximately 10 to 12 weeks without treatment. Although intra-articular corticosteroid injections are frequently performed with a low rate of complication, clinicians should be familiar with this rare yet distressing condition. Furthermore, patients with increased production of endogenous corticosteroids (eg, those with Cushing's syndrome, type A personality, hypertension, or obstructive sleep apnea) should be warned of the potential of chorioretinopathy after an intra-articular corticosteroid injection.

    A 21-year-old man presented with a complaint of hoarseness as well as lesions along the eyelids and on his knees, elbows, and fingers. Hoarseness had developed in childhood, followed by lesions along the eyelids and on the elbows and fingers. He had developed lesions on the knees, feet, scrotum, penis, and axilla over the last 2 years. His parents were relatives, but nobody in the family showed similar features. His physical examination was normal. On dermatologic examination, there were beaded papules along the eyelids and small, yellow-white infiltrations on the tongue, buccal mucosa, palate, scrotum, and penis (Fig. 1). His tongue was firm and its mobility was limited. He also had infiltration of the frenulum (Fig. 2) and warty and hyperkeratotic papular and nodular lesions on the hands, knees, elbows (Fig. 3), and axilla. The laboratory findings and laryngoscopic examination were normal. Ophthalmologic, neurologic, and psychiatric examinations were also normal. Electroencephalogram (EEG), electromyogram (EMG), craniography, and cranial computed tomography (CT) scanning revealed no abnormality. The histopathologic examination of the skin biopsy specimens obtained from the axilla, elbow, and dorsum of the hand showed hyperkeratosis and periodic acid-Schiff-positive (PAS(+)) staining hyaline material around the dermal capillaries and sweat glands, and confirmed the diagnosis of lipoid proteinosis.

    Full Text Available Introduction: The Ramsay Hunt syndrome is characterized by combination of herpes infection and lower motor neuron type of facial nerve palsy. The disease is caused by a reactivation of Varicella Zoster virus and can be unrepresentative since the herpetic lesions may not be always be present (zoster sine herpete and might mimic other severe neurological illnesses. Case Report: A 63-year-old man known case of carcinoma of gall bladder with liver metastases, post surgery and chemotherapy with no scope for further disease modifying treatment, was referred to palliative care unit for best supportive care. He was on regular analgesics and other supportive treatment. He presented to Palliative Medicine outpatient with 3 days history of ipsilateral facial pain of neuropathic character, otalgia, diffuse vesciculo-papular rash over ophthalmic and maxillary divisions of left trigeminal nerve distribution of face and ear, and was associated with secondary bacterial infection and unilateral facial edema. He was clinically diagnosed to have Herpes Zoster with superadded bacterial infection. He was treated with tablet Valacyclovir 500 mg four times a day, Acyclovir cream for local application, Acyclovir eye ointment for prophylactic treatment of Herpetic Keratitis, low dose of Prednisolone, oral Amoxicillin and Clindamycin for 7 days, and Pregabalin 150 mg per day. After 7 days of treatment, the rash and vesicles had completely resolved and good improvement of pain and other symptoms were noted. Conclusion: Management of acute infections and its associated complications in an acute palliative care setting improves both quality and length of life.

    BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (pacne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-pacne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

    Full Text Available Leishmaniasis is an infectious disease that is endemic in tropical areas and in the Mediterranean. This condition spreads to 98 countries in four continents, surpassing 12 million infected individuals, with 350 million people at risk of infection. This disease is characterized by a wide spectrum of clinical syndromes, caused by protozoa of the genus Leishmania, with various animal reservoirs, such as rodents, dogs, wolves, foxes, and even humans. Transmission occurs through a vector, a sandfly of the genus Lutzomyia. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis, and mucocutaneous leishmaniasis. The wide spectrum of nonvisceral forms includes: localized cutaneous leishmaniasis, a papular lesion that progresses to ulceration with granular base and a large framed board; diffuse cutaneous leishmaniasis; mucocutaneous leishmaniasis, which can cause disfiguring and mutilating injuries of the nasal cavity, pharynx, and larynx. Leishmaniasis/HIV coinfection is considered an emerging problem in several countries, including Brazil, where, despite the growing number of cases, a problem of late diagnosis occurs. Clinically, the cases of leishmaniasis associated with HIV infection may demonstrate unusual aspects, such as extensive and destructive lesions. This study aims to report a case of mucocutaneous leishmaniasis/HIV coinfection with atypical presentation of diffuse desquamative eruption and nasopharyngeal involvement.

    A previously well infant aged 9 months presented with an acute, self-limiting illness characterised by high fever and a papular eruption that started on the face. Although fever subsided within 3 days, the rash worsened and extended over the whole body, with some papules evolving into vesiculobullous lesions. The infant had been exposed to children with a similar illness 1 week before onset. PCR of vesicular swabs and stool samples taken on day 6 of illness showed Coxsackie virus A6. The illness resolved within 10 days of onset, although onychomadesis was seen on both big toes at follow-up 5 weeks later. Our case exemplifies the severe, atypical cases of hand, foot, and mouth disease that have been reported worldwide since 2008, and in the USA since the 2011. Atypical hand, foot, and mouth disease is caused by a new lineage of Coxsackie virus A6 and is characterised by high fever and vesiculobullous eruptions on the calves and backs of the hands. Infants with eczema might be predisposed to severe disease. Copyright © 2014 Elsevier Ltd. All rights reserved.

    A clinical analysis was made on 161 cases of hyperthyroidism seen at the Radioisotope Laboratory of Kyungpook National University Hospital. This series consisted of 144 cases of diffuse goiter and 17 cases of nodular goiter. 1) Hyperthyroidism was most prevalent in the 4th decade and male to female ratio was 1 : 4.6. 2) Cardinal symptoms in the order of frequency were weakness, easy fatigability, palpitation, weight loss, nervousness, perspiration, heat intolerance, increased appetite, insomnia and dysmenorrhoea. 3) Major physical findings in the order of frequency were goiter, fine tremor, tachycardia, wide pulse pressure, emaciation, warm moist skin, exophthalmos, systolic hypertension and atrial fibrillation. 4) The complications were ophthalmopathy (34.2%), thyrotoxic heart disease (5.6%), thyroid crisis (1 case), pretibial myxedema (1 case) and thyrotoxic myopathy (1 case). 5) Mean values of the six hour and twenty-four hour 131 I uptakes by the thyroid glands were 67.5% and 71.6%, respectively, in diffuse goiter and 64.5% and 65.0%, respectively, in nodular goiter. 6) Mean values of twenty-four PB 131 I conversion ratio were 76.3% in diffuse goiter and 70.2% in nodular goiter and those of the basal metabolic rate was +51% in the former and +41% in the latter. Mean serum cholesterol level was 152 mg% in diffuse goiter and that in nodular goiter was 175 mg%. 7) Among the 134 cases treated with 131 I, 66 cases (49.3%) were successfully controlled with single dose and in the majority of the cases the initial therapeutic dose required was 4.1-4.0 mC in diffuse goiter and 5.1-6.0 mC in nodular goiter. 8) With 131 I treatment the symptoms improved in the following order: heat intolerance, emaciation, nervousness, insomnia, easy fatigability, weakness, fine tremor, goiter, perspiration, exertional dyspnea and palpitation. And in a few cases improvement of even exophthalmos was seen. 9) Following 131 I treatment myxedema occurred in 4 cases (3%) and reoccurrence in 9

Obesity has an impact on the musculoskeletal system, leading to knee and ankle overexertion, difficulty with balance, and functional disability. The aim of this study was to identify changes in kinematic parameters of gait in obese young women. Methods: A case-control study with 24 obese women (mean age 35.20 ± 9.9 years and mean body mass index of 31.85 ± 2.94 kg/m² and 24 eutrophic women (mean age of 36.33 ± 11.14 and mean body mass index of 21.82 ± 1.58 kg/m². The gait of women was evaluated by the system Vicon Motus® 9.2. The linear parameters of speed, cadence, right and left step, and stride lengths were studied, as well as the angular parameters of knee and ankle. Results: There was a decrease in linear gait parameters (P < 0.001, speed, cadence, right and left step, and stride lengths. In regard to the angular parameters of the knee and ankle, there were also differences between the analyses (P < 0.001. At the knee joint, obese women have delayed onset of the second wave of flexion, exacerbating such movement in order to compensate. In regard to the ankle, both groups showed curves of normal plantar flexion and dorsiflexion, but there was a delay in the path graph in the ankle of obese women indicating a reduced range of motion and possible over-exertion of the pretibial

    A 78-year-old-man was admitted to our hospital because of renal insufficiency 20 months after the onset of autoimmune pancreatitis. He had cerebral infarction and prostatic hypertrophy as complications. He had been previously diagnosed with autoimmune pancreatitis (AIP). The initial therapy was started with oral prednisolone at the dose of 0.8 mg/kg (40 mg/day). Prednisolone had been tapered off gradually through a one-year period. Four months later from terminating prednisolone, a follow-up CT showed multiple low-density areas in both kidneys without swelling of the pancreas. Furthermore, 4 months later, laboratory findings showed progressive renal insufficiency. On admission, BP was 167/77 mmHg, and the bilateral submaxillary glands were swollen. He did not have pretibial edema. Laboratory findings were as follows. BUN 55.9 mg/dL, Cre 6.17 mg/dL, Amy 65 mg/dL, TP/Alb 9.5/4 g/dL, gamma-gl 43.7%, IgG/IgA/IgM 3,395/112/74 mg/dL, IgG4 1,460 mg/dL, urinary protein 1.38 g/day, and 24 hr-Ccr 11.8 mL/min/1.73 m2. Percutaneous renal needle biopsy was conducted. Light microscopic findings demonstrated tubulointerstitial nephritis (TIN) and membranous change. Immunofluorescent microscopic findings indicated diffuse deposition of IgG2 and IgG4 in the renal interstitium. On the basis of these findings, the condition was diagnosed as IgG4-related tubulointerstitial nephritis. As renal insufficiency was progressing, hemodialysis was started soon after admission and oral prednisolone was also started at the dose of 0.4 mg/kg (20 mg/day). However, improvement of renal function has not been obtained and hemodialysis and prednisolone tapering are still being conducted. This case showed severe tubulointerstitial nephritis requiring hemodialysis after a cure for autoimmune pancreatitis. IgG4-related renal disease rarely needs hemodialysis. This case indicates that the prognosis of IgG4-related systemic disease is not necessarily good and further accumulation of cases is required.

    The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported. These atypical skin eruptions often present in addition to the typical evanescent rash but may also be the only skin manifestation, resulting in delayed diagnosis because of under-recognition.In this study, we present 3 new cases of AOSD with atypical cutaneous manifestations diagnosed during a 30-year period in our department and review 78 additional cases previously reported (PubMed 1990-2016). These 81 patients form the basis of the present analysis.The overall prevalence of atypical cutaneous manifestations in our AOSD population was 14%. These manifestations may appear at any time over the course of the disease, and usually occur in patients who have persistent and severe disease, with a considerable frequency of clinical complications (23%), including serositis, myopericarditis, lung involvement, abdominal pain, neurologic involvement, and reactive hemophagocytic syndrome.The most representative and frequent lesion among the nonclassical skin rashes is the development of persistent pruritic papules and/or plaques. Interestingly, these lesions show a distinctive histological pattern. Other, less frequently observed lesions include urticaria and urticaria-like eruptions, generalized or widespread non-pruritic persistent erythema, vesiculopustular eruptions, a widespread peau d'orange appearance of the skin, and edema of the eyelids mimicking dermatomyositis without any accompanying skin lesion.The great majority of these patients required medium or high doses of glucocorticoids (including intravenous methylprednisolone pulse therapy in some cases) and, in nearly 40%, a more potent or maintenance immunotherapy with

  10. The Histamine H4 Receptor: From Orphan to the Clinic

    Full Text Available The histamine H4 receptor (H4R was first noted as a sequence in genomic databases that had features of a G-protein coupled receptor. This putative receptor was found to bind histamine consistent with its homology to other histamine receptors and thus became the fourth member of the histamine receptor family. Due to the previous success of drugs that target the H1 and H2 receptors, an effort was made to understand the function of this receptor and determine if it represented a drug target. Taking advantage of the vast literature on histamine, a search for histamine activity that did not appear to be mediated by the other three histamine receptors was undertaken. From this asthma and pruritus emerged as areas of particular interest. Histamine has long been suspected to play a role in the pathogenesis of asthma, but antihistamines that target the H1 and H2 receptors have not been shown to be effective for this condition. The use of selective ligands in animal models of asthma has now potentially filled this gap by showing a role for the H4R in mediating lung function and inflammation. A similar story exists for chronic pruritus associated with conditions such as atopic dermatitis. Antihistamines that target the H1 receptor are effective in reducing acute pruritus, but are ineffective in pruritus experienced by patients with atopic dermatitis. As for asthma, animal models have now suggested a role for the H4R in mediating pruritic responses, with antagonists to the H4R reducing pruritus in a number of different conditions. The anti-pruritic effect of H4R antagonists has recently been shown in human clinical studies, validating the preclinical findings in the animal models. A selective H4R antagonist inhibited histamine-induced pruritus in health volunteers and reduced pruritus in patients with atopic dermatitis. The history to date of the H4R provides an excellent example of the deorphanization of a novel receptor and the translation of this into

    Full Text Available Abstract Introduction Atopic dermatitis is a chronic, pruritic, eczematous skin disease mediated through an immediate (type I hypersensitivity reaction. Posterior sub-capsular cataracts are a recognised complication of atopic dermatitis in adults; however they are rare in children. The management of atopic dermatitis is based on the exclusion of allergens, the use of emollients, and on topical corticosteroids for disease exacerbations. Cataracts may be due to atopic dermatitis but may also occur secondary to the use of corticosteroids. Case presentation We describe two children with atopic dermatitis, treated with cutaneous corticosteroids, both of whom were diagnosed with bilateral posterior sub-capsular cataracts. Conclusion These cases demonstrate that atopic dermatitis and topical corticosteroids may be associated with cataracts in children as well as adults. The cause of cataracts in atopic dermatitis is not known, however, it has been suggested that habitual tapping and rubbing of the face may play a role. Care needs to be taken when prescribing corticosteroids. Inadequate treatment of atopic dermatitis may lead to other ocular complications such as keratitis and permanent visual loss.

    The GERDA classes have the function of updating our knowledge of dermato-allergology. One of the themes tackled this year was the treatment of atopic dermatitis. Apart from consideration of treatment or exception with cortisone, it seemed to be of interest to find the relevance of "old treatments" for atopic dermatitis, either preventive or symptomatic. Preventive treatment made reference to correction of food factors (diet in infants, removal of maternal allergens, supplementation on fatty acids) and of environmental factors especially the fight against house dust mites by use of anti-mite mattress covers. Miracle treatments of atopy do not always exist. Thus there is often need for, besides local corticosteroid therapy, an external symptomatic treatment where the emphasis is on the struggle against skin microbiology, the fight against pruritic inflammatory conditions and above all the battle against xerosis. Knowledge of the physiology of the stratum corneum gives better understanding of the effect of emollients and moisturizers in restoration of the cutaneous barrier, of which dysfunction is one of the elements of atopic dermatitis.

    Full Text Available Mansonella ozzardi is a filarial autochthonous parasite of the American continent that is frequently found infecting human beings in the Brazilian Amazon. The human infection by M. ozzardi is still seen as non pathogenic despite the variety of symptoms related to it such as fever, articular pain, headache, lymphadenopathy, eosinophily and pruritic skins eruptions. During an expedition in the Acre State, we were able to visit the Kamikuã, an Indian village located along the Purus river, close to the city of Boca do Acre (Amazonas State. The inhabitants had been diagnosed as harboring dog´s worms (Dirofilaria immitis but our blood samples collections from some individuals evidenced M. ozzardi infections. In fact, human populations from endemic areas are always complaining about symptoms of M. ozzardi infection and remain living together with high parasitic loads in the expectation of correct diagnostic and treatment. Studies on mansonellosis chemotherapy and control should be carried out in order to add knowledge about the infection and to provide hope and answers for those who live in endemic areas.

    Since 2000, resurgence in bed bugs has occurred in the U.S. Reports of infestations of homes, hospitals, hotels, and offices have been described. On September 1, 2011, complaints of itching and bites among workers in an office were reported to the Tennessee Department of Health. A retrospective cohort study and environmental assessments were performed in response to the complaints. Canines certified to detect live bed bugs were used to inspect the office and arthropod samples were collected. Of 76 office workers, 61 (80%) were interviewed; 39 (64%) met the case definition. Pruritic maculopapular lesions were consistent with arthropod bites. One collected arthropod sample was identified as a bed bug by three entomologists. Exposures associated with symptoms included working in a cubicle in which a canine identified bed bugs (risk ratio [RR]: 1.8; 95% confidence interval [CI]: 1.3-3.6), and self-reported seasonal allergies (RR: 1.6, 95% CI: 1.0-2.4). Bed bugs represent a reemerging and challenging environmental problem with clinical, psychological, and financial impacts.

    Atopic dermatitis (AD) is a pruritic and chronic inflammatory skin disease which affected approximately 20% in children. Bacterial infection is common in AD patients and correlates directly with AD severity. A cross-sectional study was conducted to evaluate the prevalence of bacterial skin infection in AD patients and its relation with severity of AD and also to study bacteria in the infected AD and its antibiotic sensitivity. Samples were 86 children and adolescents with an AD in Helvetia Community Health Center Medan from March 2016 until February 2017. Index of SCORing Atopic Dermatitis (SCORAD) was used to evaluate the severity of AD. Lesion and nonlesional skinwere swabbed to take sterile cultures. All bacteria noted and tested for antibiotic sensitivity. Datawere by using Chi-Square and Mann Whitney test with 95% CI and p-value<0.05 was considered statistically significant. Fifty-six AD patients (65.1%) were bacterial infected. There was a significant relationship between severity of AD and bacterial infection (p = 0.006). Staphylococcus aureus was the leading bacteria from all degrees of AD severity. Isolated Staphylococcus aureuswas sensitive to amoxicillin-clavulanate (93.3%), clindamycin (90%), erythromycin (90%), and gentamicin (90%), while sensitivity to tetracycline was low (20%).

    Scabies infestation is one of the most pruritic dermatoses of dogs. It is often misdiagnosed and dogs are treated with immunomodulatory drugs (IMD) to relieve pruritus. The primary goals of this study were to determine the impact of IMD on skin scraping results, pruritus level and extent of skin lesions, and to evaluate whether disease duration is associated with positive skin scrapings and contagion. Seventy nine dogs with a final diagnosis of scabies. Inclusion in this retrospective study required a positive skin scraping for scabies or a clinical response to an acaricidal treatment trial. The average pruritus score of dogs that received IMD (8.71) was significantly higher than those that did not (7.43; P = 0.03). However, there were no significant differences in either the rates of positive skin scrapings (79.6% versus 59.1%; P = 0.13) or the mean number of body sites affected (3.8 versus 3.4; P = 0.30) between dogs that received IMD and those that did not. Neither skin scraping status nor duration of clinical signs were correlated with a report of contagion within the household. IMD was associated with a significant increase in the pruritus level, but not with the mean number of lesional body sites. Dogs exposed to IMD had a 20.5% higher rate of positive skin scrapings. This difference could be clinically relevant and lack of statistical significance may indicate an underpowered study. © 2016 ESVD and ACVD.

    Full Text Available Introduction. Ecthyma contagiosum is a zoonotic disease caused by the parapoxvirus that causes “sore mouth” in sheep and goats and orf in human. Case Presentation. A 61-year-old sheep farmer presented with a painful non-pruritic lesion on the left hand that had been present for approximately 5 weeks. Physical examination demonstrated a 1 cm pearly, umbilicated papule with raised borders. A biopsy showed an asymmetrical nodule with parakeratotic crust and acanthosis with thin epidermal strands extending deeply in the underlying dermis. Marked edema, capillary proliferation and extensive lymphocytic infiltration was also present. One red intranuclear inclusion was identified in an epidermal keratinocyte. A diagnosis of human orf (ecthyma contagiosum was made. Conclusion. Infected sheep and freshly vaccinated sheep or goats are the reservoir for human infection. After an incubation period of 3–7 days, parapoxvirus infections produce 1–3 painful lesions measuring 1-2 cm in diameter. The natural history of the disease is complete resolution and no treatment is indicated. Prevention of echthyma contagiosum in ruminants through vaccination is thought to be the best way to control infection.

    Full Text Available BACKGROUND: Lichen amyloidosus (LA is a primary localized cutaneous amyloidosis characterized clinically by discrete hyperkeratotic hyperpigmented papules and histologically by deposition of amyloid material in previously normal skin without any evidence of visceral involvement. AIMS AND OBJECTIVES: The aim of this work was to study the etiology, clinical features, histopathology and direct immunofluorescence findings in LA. METHODS: A prospective study of 30 patients with clinical, histological and immunofluorescence findings suggestive of LA was undertaken. After a detailed history and clinical examination, two punch biopsies for histopathology and immunofluorescence were taken. RESULTS: Of the 30 patients, 19 (63.3% were males and 11 (36.7% were females with duration of LA ranging from 6-20 months. Pruritus was the presenting symptom in 27 (90% patients. Shin was involved in 26 (86.7% followed by arms in three (10% and back in one (3.3%. Seventeen patients (56% had used scrubs for more than 2 years. Histopathology, direct immunofluorescence and Congo red staining detected amyloid in all cases. CONCLUSIONS: LA commonly presents over the shins as pruritic discrete hyperpigmented papules. Familial predisposition and friction may have a pathogenic role. Histopathological examination is very useful in the detection of amyloid which may be supplemented with direct immunofluorescence and Congo red staining.

    Full Text Available This paper describes the case of a one-year-old female American Pit Bull Terrier, presented with the history of progressive baldness. The initial clinical signs were demonstrated by symmetric, primarily non-pruritic alopecia that began in the perineal, genital, and ventral abdominal regions and propagated cranially to the thorax and to the neck. Based on physical and dermatological examination, laboratory findings, and results of skin biopsy, a hormone-responsive dermatosis was diagnosed. Once hypothyroidism and hyperadrenocorticism were ruled out, with the help of hormonal tests, the diagnosis was specified as alopecia X. The first treatment option recommended for the patient and subsequently completed was ovariohysterectomy. After three months, the owner reported improvement; the dog was almost covered with hair. The patient was presented again six months later, showing almost the same dermatological symptoms, which, however, were of a more striking character than before ovariohysterectomy. Again a series of hormonal tests was carried out. Considering the elevated basal and post-adrenocorticothropin stimulation progesterone concentrations, the final aetiology of the disease was determined as an adrenal sex hormone imbalance. Therefore trilostan therapy was initiated. The trilostan dosage of 8 mg/kg/day was divided and given 2 times daily. This treatment led to complete hair regrowth in the dog within four months. No adverse effects associated with trilostane were recognized.

    Demodicidosis is an ectoparasitosis, common to humans and many mammals. It is caused by the proliferation of a mite Demodex sp in the pilosebaceous follicles. Its pathogenic role remains controversial. The aim of our study was to report epidemiological and clinical particularities of cases of demodicidosis diagnosed in our region. Over a period of nine years (January 2000 to December 2008), 427 cases of demodicidosis were diagnosed. 73.2% of cases were blepharitis and 26.8% of cases were facial dermatosis. The mean age was 44 years. Women were slightly more affected (56%) than men. Among 787 chronic blepharitis, 243 cases were due to Demodex sp (30.9%). They were treated with yellow oxide of mercury (Ophtergine® 1%). In the face, this mite has been isolated from erythematous and pruritic papulopustular lesions, and their distribution was as follows: cheeks (22.1%), forehead (13.4%), and nose (11.5%). The diagnosis was confirmed by parasitological examination of scales showing more than 5 Demodex sp/cm(2) and response to treatment with metronidazole (Flagyl®) for three months. Currently, there were a large number of arguments for the incrimination of Demodex sp in pathogenesis of dermatosis and blepharitis. Dermatologists and ophthalmologists must therefore think to this mite. The density of Demodex sp found by parasitological exam is a determining factor in establishing an anti-Demodex treatment whose effectiveness is a further argument for the diagnosis.

    BACKGROUND Paracoccidioidomycosis is an endemic mycosis in Central and South America caused by the thermally dimorphic fungus Paracoccidioides brasiliensis. Despite its self-limited course and usually asymptomatic infection, some patients may present with a systemic illness mimicking multiple conditions and thus question the general state of their immune system. CASE REPORT A 28-year-old male presented to the hospital with fever, dry cough, and non-pruritic rash with no characteristic distribution for the past 10 days. Past medical history revealed that the patient had worked as a farmer three years ago, had abused cocaine paste over the same period, and also had in the last month presented to the hospital for acute appendicitis. Initial laboratory tests revealed hypereosinophilia greater than 10,000 eosinophils/mL. Infection of P. brasiliensis was confirmed by lymph node, skin, and colonoscopy biopsies. After treatment with itraconazole, the patient's eosinophil count returned to normal and his symptoms resolved. CONCLUSIONS Paracoccidioidomycosis may present as a systemic illness with only marked eosinophilia on initial diagnostic tests. Furthermore, in our patient's case, the high degree of eosinophilia may have contributed towards the patient's appendicitis in the weeks preceding the subacute infection. It is possible that the patient's history of working at a farm and abusing cocaine paste may have contributed to the initial colonization by the fungus.

    Chronic urticaria (CU) is defined as the occurrence of spontaneous wheals for a duration of more than 6 weeks and is the most frequent skin disease, with prevalence ranging between 15 and 25%, and is a seriously disabling condition, with social isolation and mood changes causing a significant degree of dysfunction and quality of life impairment to many patients. The main clinical features of CU are the repeated occurrence of transient eruptions of pruritic wheals or patchy erythema on the skin that last less than 24 hours and disappear without sequelae. CU is often defined as chronic idiopathic urticaria (CIU) because the causes of CU remain unknown in the great majority (70-95%) of patients. Drugs, food, viruses, alimentary conservative substances or inhalant substances often seem to be involved in determining CIU skin flare. Despite a general agreement that bacteria infections and parasitic infestations can be involved in the pathogenesis of CIU, proven evidence of these relationships is lacking. The aim of the present study is to evaluate the prevalence of Helicobacter pylori (Hp) infection, and the extension and severity of gastritis in a group of CIU patients compared to controls and to evaluate the effectiveness of eradication of Hp on the CIU symptomatology, and the role of Hp infection in pathogenesis of CIU.

    Classic Hodgkin lymphoma with pelvic involvement is a rare entity. Diagnosis and treatment for such an uncommon disease are challenging. Here we report a special case of classic Hodgkin lymphoma in pelvis. A 20-year-old woman was admitted to our department due to left hip symptoms. The patient reported a history of drenching night sweats, low-grade fever, pruritic rash on the body, and an almost 15% weight loss during the previous 3 months. Imaging studies revealed osteolytic destruction of the left hemi-pelvic with a huge soft-tissue mass. Open biopsy established the pathological diagnosis of classic Hodgkin lymphoma. Considering the B symptom, bulky disease, and high risk of pathological fracture of the patient, we performed limb-salvage surgery and 6 cycles ABVD chemotherapy with 2 cycles before surgery. Up to now, at the 3-year follow-up, there is no sign of disease relapse and metastasis. Besides, her limb function recovered well. Based on this case and literature we reviewed, diagnoses for primary bone Hodgkin lymphoma should be cautious. For the treatment, chemotherapy was the main treatment option. Classic Hodgkin lymphoma patients seldom received tumor resection surgery, but for the special bone classic Hodgkin lymphoma individual with a huge tumor volume and high risk of pathological fracture in our study, limb-salvage surgery based on ABVD chemotherapy provided a satisfying clinical outcome.

  5. A Case Report of Rash at Peritoneal Dialysis Exit Site

    2015-11-01

    Full Text Available The International Society for Peritoneal Dialysis recommends the regular application of topical antibiotic-containing preparations in addition to a routine exit site care to reduce the risk of exit site infection (ESI. Among these prophylactic antimicrobial preparations, topical gentamicin is one of the widely used and effective antibiotics for prevention of ESI and peritonitis in peritoneal dialysis (PD patients. Overall, topical gentamicin is well tolerated; however, its use can be associated with the development of allergic contact dermatitis (ACD. We describe a first reported case of PD catheter exit site contact ACD due to topical gentamicin mimicking ESI. The patient in this report developed worsening violaceous in color and pruritic rash surrounding the PD catheter exit site that appeared 3 weeks after the initiation of gentamicin cream. The association between development of rash and initiation of topical gentamicin led to a suspicion of local reaction to gentamicin rather than ESI. Skin biopsy confirmed ACD. Discontinuation of the provoking agent and subsequent treatment with topical hydrocortisone application led to a resolution of the exit site rash. Any rash at a PD catheter exit site should be considered infectious until proven otherwise. However, it is important to be aware of noninfectious etiologies of exit site rashes as the treatment of these 2 conditions differs.

    Uremic pruritus is a common complication in patients with chronic kidney disease. While its cause is not known for certain, different treatments are currently applied. This study aimed to compare the effects of Avena sativa, diluted vinegar, and hydroxyzine on the reduction of uremic pruritus. In this crossover randomized clinical trial, 23 hemodialysis patients with uremic pruritus were randomly divided into 3 groups. The first group was treated with Avena sativa lotion, twice a day, for as long as 2 weeks; the second group received diluted vinegar; and the third group took hydroxyzine tablets for the same time span. After 3-day-long washout periods, the therapeutic methods were crossed over. The data were collected by a pruritus scale and a visual analogue scale, which were completed before and after the interventions. Avena sativa lotion significantly decreased the mean scores of pruritus intensity, consequences, and the verbal descriptor, although it did not have a significant effect on the frequency of pruritus and the pruritic surface. Vinegar and hydroxyzine significantly decreased all of the scores.  Conclusions. Avena sativa, vinegar, and hydroxyzine were effective in decreasing pruritus. Diluted vinegar and Avena sativa can be used as a complement to hydroxyzine, which is itself a common pharmaceutical therapy.

    Full Text Available Familial lichen amyloidosis which is also referred to familial primary cutaneous amyloidosis is a rare clinical variant of cutaneous amyloidosis. Lichen amyloidosis is characterized by persistent, pruritic, small brown papules often located on anterior surfaces of legs which show tendency to form plaques. Amyloid deposits would be identified in papillary dermis in histopathological examination. In our clinic, a 42 year old woman with a widespread involvement describing that similar skin findings were present in her both daughters, elder brother and her nephew was evaluated with suspicion of lichen amyloidosis. In histopathological examination of the involved skin, because of determining amyloid deposits in papillary dermis the case was cited as lichen amyloidosis. Our case was searched for the accompanying diseases such as atopic dermatitis, chronic urticaria, lichen planus, multiple endocrine neoplasia and Kimura disease. The family history of our patient was consistent with autosomal dominant inheritance. Familial lichen amyloidosis has been reported as cases with autosomal dominant inheritance from Russia, Germany, United Kingdom and South America. The genetic researches over familial lichen amylodiosis are limited to the cases with multiple endocrine neoplasia. In this rarely reported cases, further genetical researches are necessary in order to determine the responsible gen locus. (Turkderm 2008; 42: 137-9

    Human dermatophytic cutaneous infections usually present as single or multiple slowly progressing annular erythemato-squamous lesions with a tendency to central healing on the hairless skin. In the intertriginous regions (feet, inguinal, axillar, submammary), dermatophytic colonisations and infections manifest as whitish, slightly hyperkeratotic, pruritic and sometimes fissurated lesions. On the scalp, dermatophytic infections commonly lead to single or multiple more or less inflammatory and alopecic lesions. On the plantar and palmar aspects of the feet and hand, dermatophytosis presents as an eczema-like chronic dermatosis. Abscess-like lesions may occur due to zoophilic dermatomycosis. Dermatophytic infections of the nails reveal ill-defined whitish-yellowish colorations of the distal end or the lateral aspects of the nails, sometimes combined with partial nail embrittlement or even complete destruction. Despite the ubiquity of dermatophytic skin infections and their usually highly typical clinical features, a differential diagnosis has to be considered, in particular when treatment is not efficient or when treatment resistance occurs. This review presents the differential diagnosis in terms of frequency as well as the diagnostic methods permitting the distinction of annular, intertriginous, alopecic, palmoplantar, abscess-like and onychodystrophic lesions.

    Full Text Available Abstract Background The neurocircuits that process somatic sensory information in the dorsal horn of the spinal cord are still poorly understood, with one reason being the lack of Cre lines for genetically marking or manipulating selective subpopulations of dorsal horn neurons. Here we describe Tac2-Cre mice that were generated to express the Cre recombinase gene from the Tac2 locus. Tachykinin 2 (Tac2 encodes a neurotransmitter, neurokinin B (NKB. Results By crossing Tac2-Cre mice with ROSA26-tdTomato reporter mice, we directly visualized Tac2 lineage neurons in the dorsal root ganglia, the dorsal horn of the spinal cord, and many parts of the brain including the olfactory bulb, cerebral cortex, amygdala, hippocampus, habenula, hypothalamus, and cerebellum. This Tac2-Cre allele itself was a null allele for the Tac2 gene. Behavioral analyses showed that Tac2 homozygous null mice responded normally to a series of algogenic (pain-inducing and pruritic (itch-inducing stimuli. Conclusions Tac2-Cre mice are a useful tool to mark specific subsets of neurons in the sensory ganglia, the dorsal spinal cord, and the brain. These mice can also be used for future genetic manipulations to study the functions of Tac2-expressing neurons or the functions of genes expressed in these neurons.

    Full Text Available Abstract Background Anetoderma is a benign condition with focal loss of dermal elastic tissue resulting in localized areas of flaccid or herniated saclike skin. Currently, anetoderma is classified as either primary (idiopathic, or secondary anetoderma (which is associated with a variety of skin conditions, penicillamine use, or neonatal prematurity. Lesions appear on the upper arms, trunk, and thighs. Case presentation We report a 14-year-old boy, which was noticed to have had multiple, white, non-pruritic areas on the acral sites of upper and lower extremities for two years. In physical examination, the patient had normal mental development. Skin lesions consisted of scattered, white to skin-colored papules, less than 1 cm in diameter, and with central protrusion, with distribution on dorsal part of the index finger, forearms, distal portion of thighs and calves. Lesions were detected neither on the trunk nor the proximal areas of extremities. There are no sensory changes associated with the lesions. Otherwise, his general health was good. He did not have any medication consumption history. Family history was negative. Laboratory examinations were within normal limits. Skin biopsy from one of his lesions was done, that confirmed the diagnosis of anetoderma. Conclusions In summary, we report a case of anetoderma on unusual sites of the skin. We could not find similar reports of anetoderma developing on distal extremities without involvement of the upper trunk and proximal arms, in the medical literature.

    Intradermal cheek injection of pruitogens or algogens differentially elicits hindlimb scratching or forelimb wiping, suggesting that these behaviors distinguish between itch and pain. We studied whether pruritogens and algogens excite separate or overlapping populations of primary afferent and second-order trigeminal neurons in mice. Calcium imaging of primary sensory trigeminal ganglion (TG) cells showed that 15.4% responded to histamine, 5.8% to the protease-activated receptor (PAR)-2 agonist, 13.4% to allyl isothiocyanate (AITC), and 36.7% to capsaicin. AITC and/or capsaicin activated the vast majority of histamine- and PAR-2 agonist-sensitive TG cells. A chemical search strategy identified second-order neurons in trigeminal subnucleus caudalis (Vc) responsive to histamine, the PAR-2 agonist, or AITC. A minority of histamine or PAR-2 agonist-responsive Vc neurons responded to the other pruritogen, whereas a large majority of puritogen-responsive Vc neurons responded to capsaicin and/or AITC. A minority of AITC-responsive Vc neurons responded to pruritogens, whereas most responded to capsaicin. These data indicate that most primary and higher-order trigeminal sensory neurons are activated by both pruritic and algesic stimuli, although a minority exhibit selectivity. The results are discussed in terms of population codes for itch and pain that result in distinct behavioral responses of hindlimb scratching and forelimb wiping that are mediated at lumbar and cervical segmental levels, respectively.

  13. Glutamate acts as a neurotransmitter for gastrin releasing peptide-sensitive and insensitive itch-related synaptic transmission in mammalian spinal cord

    Full Text Available Abstract Itch sensation is one of the major sensory experiences of human and animals. Recent studies have proposed that gastrin releasing peptide (GRP is a key neurotransmitter for itch in spinal cord. However, no direct evidence is available to indicate that GRP actually mediate responses between primary afferent fibers and dorsal horn neurons. Here we performed integrative neurobiological experiments to test this question. We found that a small population of rat dorsal horn neurons responded to GRP application with increases in calcium signaling. Whole-cell patch-clamp recordings revealed that a part of superficial dorsal horn neurons responded to GRP application with the increase of action potential firing in adult rats and mice, and these dorsal horn neurons received exclusively primary afferent C-fiber inputs. On the other hands, few Aδ inputs receiving cells were found to be GRP positive. Finally, we found that evoked sensory responses between primary afferent C fibers and GRP positive superficial dorsal horn neurons are mediated by glutamate but not GRP. CNQX, a blocker of AMPA and kainate (KA receptors, completely inhibited evoked EPSCs, including in those Fos-GFP positive dorsal horn cells activated by itching. Our findings provide the direct evidence that glutamate is the principal excitatory transmitter between C fibers and GRP positive dorsal horn neurons. Our results will help to understand the neuronal mechanism of itch and aid future treatment for patients with pruritic disease.

    Atopiclair (Zarzenda) is a topical non-steroidal anti-inflammatory agent for the treatment of allergic diseases of the skin. Three main ingredients are contained in this product: glycyrrhetinic acid, telmesteine and Vitis vinifera extracts. Other ingredients include: allantoin, alpha-bisabolol, capryloyl glycine, hyaluronic acid, shea butter and tocopheryl acetate. Two previous randomized, double-blind, vehicle-controlled clinical studies provided evidence that Atopiclair is effective in the treatment of atopic dermatitis. This article presents an open, multicenter, sponsor-free, study on the anti-pruritic activity of this product in adult patients with mild-to-moderate atopic dermatitis. The Median Visual Analogue Scale (VAS) values were: at the start of the study (TO), median VAS was 48.5 mm; three weeks later (T1), median VAS was 34.1 mm (-14.4 mm from baseline); six weeks later (T2), median VAS was 24.6 mm (-23.9 mm from baseline). Statistical analysis revealed that differences between TO versus T1, TO versus T2 and T1 versus T2 were highly significant (p<0.001). Side effects (local burning) were relatively common, although mild in severity. On the basis of the results of this study, Atopiclair showed efficacy in relief of pruritus in adult patients with mild-to-moderate atopic dermatitis.

    Intrahepatic cholestasis of pregnancy (ICP) is characterized by the occurrence of pruritus mostly in the third trimenon. Diagnosis is based on the presence of pruritus and elevated levels of serum bile acids in the absence of pruritic skin diseases. There is strong evidence of a genetic predisposition for ICP. Numerous studies have investigated the association of known cholestasis genes such as ABCB4 (also designated MDR3), ABCB11 ( BSEP) and ATP8B1 ( FIC1) with ICP. The results of these studies implicate a heterogeneous etiology of this syndrome. ICP increases the risk of preterm delivery and fetal loss. Furthermore, intense pruritus may necessitate premature induction of labor with its known higher frequency of complications for mother and child. Therefore, ICP pregnancies should be managed as high-risk pregnancies. Pharmaceuticals to alleviate pruritus or improve cholestasis like antihistamines, phenobarbital, anion exchange resins, dexamethasone or S-adenosylmethionine are not widely accepted because of questionable efficacy or side effects. Recent randomized studies have shown beneficial effects of ursodeoxycholic acid (UDCA) on laboratory data and pruritus in patients with ICP. Improved knowledge about the diagnostic classification of different types and pathophysiological mechanisms of ICP may allow for a more targeted treatment of this disease in future.

    Canine atopic dermatitis is a common clinical presentation. The skin barrier seems to play a fundamental role in the pathogenesis. Therefore a topical spot-on product containing a mixture of lipids may improve clinical signs without adverse effects if it were to improve stratum corneum barrier function. Twenty six privately owned atopic dogs of different breed, age, gender and weight were included in a double blind, randomized, placebo-controlled study. To evaluate potential clinical benefits and influence on skin barrier function of a topical lipid-containing product applied to the skin of atopic dogs. Atopic dermatitis was diagnosed by adequate testing and the exclusion of other possible pruritic diseases. Dogs were randomly allocated to two treatment groups. A spot-on product containing different types of lipids was applied twice weekly to predisposed and affected areas. The placebo preparation contained only the excipients. The clinical effects were regularly verified with a Visual Analog Score and the Canine Atopic Dermatitis Extent and Severity Index. A medication score was calculated and barrier function was evaluated by means of transepidermal water loss and pH measurements. Twenty three dogs completed the study. There were no significant differences between the groups for any of the evaluated parameters. Adverse effects were not noted. This study could not confirm significant clinical improvement when using the product compared to the placebo, although its use was not associated with adverse effects. © 2017 ESVD and ACVD.

    Wound healing in a pre-existing Th2-dominated skin milieu was assessed by using an epidermal specific interleukin-4 (IL-4) transgenic (Tg) mouse model, which develops a pruritic inflammatory skin condition resembling human atopic dermatitis. Our results demonstrated that IL-4 Tg mice had delayed wound closure and re-epithelialization even though these mice exhibited higher degrees of epithelial cell proliferation. Wounds in IL-4 Tg mice also showed a marked enhancement in expression of inflammatory cytokines/chemokines, elevated infiltration of inflammatory cells including neutrophils, macrophages, CD3+ lymphocytes, and epidermal dendritic T lymphocytes. In addition, these mice exhibited a significantly higher level of angiogenesis as compared to wild type mice. Furthermore, wounds in IL-4 Tg mice presented with larger amounts of granulation tissue, but had less expression and deposition of collagen. Taken together, an inflamed skin condition induced by IL-4 has a pronounced negative influence on the healing process. Understanding more about the pathogenesis of wound healing in a Th2- dominated environment may help investigators explore new potential therapeutic strategies. PMID:26752054

    Full Text Available Cutaneous vasculitis can be cause by multiple disorders or can be idiopathic. Many diseases can present with similar findings, therefore histopathologic examination is always require for confirming the right diagnosis. The erythema elevatum diutinum (EED is a localized vasculitis, classified as a neutrophilic dermatosis. It’s a rare cutaneous condition, distribute on the extensor surface of the extremities, more frequently in the dorsum of the hands, knees and elbows. They have a symmetric distribution and can be asymptomatic, painful; or pruritic, sometimes accompanied paresthesias. The most common clinical presentation is round erythematous papules which become erythemato-violaceous or purpuric plaques. There are not pathognomonic histopathological findings, but can present as a leukocytoclastic vasculitis with perivascular neutrophilic infiltration in the middle and superficial dermis. I presented the case of a 61-year-old female, with erythematous purpuric painful plaques, irregular, symmetric and elevated, located in both thenar regions of her hands and paresthesias. The patient’s presentation is consistent with multiple characteristics of EED such as the description of the lesions, the anatomical location, the symmetric distribution and the histopathological findings of an initial disease. This patient does not have all the clinical progression and outcome, due to the initial stage of the disease.

    Full Text Available Emiliano Antiga, Marzia Caproni Department of Surgery and Translational Medicine, Section of Dermatology, University of Florence, Florence, Italy Abstract: Dermatitis herpetiformis (DH is an inflammatory cutaneous disease with a chronic relapsing course, pruritic polymorphic lesions, and typical histopathological and immunopathological findings. According to several evidences, DH is considered the specific cutaneous manifestation of celiac disease, and the most recent guidelines of celiac disease have stated that, in celiac patients with a proven DH, a duodenal biopsy is unnecessary for the diagnosis. In this review, the most recent data about the diagnosis and the management of DH have been reported and discussed. In particular, in patients with clinical and/or histopathological findings suggestive for DH, the finding of granular IgA deposits along the dermal–epidermal junction or at the papillary tips by direct immunofluorescence (DIF assay, together with positive results for anti-tissue transglutaminase antibody testing, allows the diagnosis. Thereafter, a gluten-free diet should be started in association with drugs, such as dapsone, that are able to control the skin manifestations during the first phases of the diet. In conclusion, although DH is a rare autoimmune disease with specific immunopathological alterations at the skin level, its importance goes beyond the skin itself and may have a big impact on the general health status and the quality of life of the patients.

    Full Text Available IgA pemphigus (IGAP is a rare autoimmune bullous disease characterized by IgA deposits on keratinocyte cell surfaces. The IGAP is classified into: 1 subcorneal pustular dermatosis (SPD type, and 2 intraepidermal neutrophilic (IEN IgA dermatosis type. So far, only 9 children with IGAP have been described in the literature, of whom only 3 with SPD type. We report a 3-year-old boy with SPD type of IGAP. Clinically, he presented with pruritic vesicles, pustules and erosions on the face, trunk, groin area, and extremities. Histopathology showed subcorneal pustules containing a few acantholytic cells. Direct immunofluorescence (DIF test of Tzanck smear showed intercellular IgA deposits on the surface of the groups of epidermal cells. Oral dapsone and prednisone induced remission after two weeks; the treatment was discontinued 11 months later, and complete remission was achieved during 19 months without any treatment. Direct immunofluorescence of Tzanck smear is a simple, sensitive, rapid and non-aggressive test, very suitable for the diagnosis of IGAP in children.

  2. Atopic dermatitis: immune deviation, barrier dysfunction, IgE autoreactivity and new therapies

    2017-07-01

    Full Text Available Atopic dermatitis (AD is a chronic or chronically relapsing, eczematous, severely pruritic skin disorder mostly associated with IgE elevation and skin barrier dysfunction due to decreased filaggrin expression. The lesional skin of AD exhibits Th2- and Th22-deviated immune reactions that are progressive during disease chronicity. Th2 and Th22 cytokines further deteriorate the skin barrier by inhibiting filaggrin expression. Some IgEs are reactive to self-antigens. The IgE autoreactivity may precipitate the chronicity of AD. Upon activation of the ORAI1 calcium channel, atopic epidermis releases large amounts of thymic stromal lymphopoietin (TSLP, which initiates the Th2 and Th22 immune response. Th2-derived interleukin-31 and TSLP induce an itch sensation. Taken together, TSLP/Th2/Th22 pathway is a promising target for developing new therapeutics for AD. Enhancing filaggrin expression using ligands for the aryl hydrocarbon receptor may also be an adjunctive measure to restore the disrupted barrier function specifically for AD.

    Atopic dermatitis (AD) is a common allergic skin disease that is associated with chronic, recurrent eczematous and pruritic lesions at the flexural folds caused by interacting factors related to environmental and immune system changes. AD results in dry skin, and immunoglobulin E-mediated allergic reactions to foods and environmental allergens. While steroids and anti-histamines temporarily relieve the symptoms of AD, the possibility of side effects from pharmacological interventions remains. Despite intensive research, the underlying mechanisms for AD have not been clarified. A study of Staphylococcus aureus (S. aureus) established the role of its toxins in the pathogenesis of AD. Approximately 90% of patients with AD experience S. aureus colonization and up to 50%–60% of the colonizing S. aureus is toxin-producing. Any damage to the protective skin barrier allows for the entry of invading allergens and pathogens that further drive the pathogenesis of AD. Some natural toxins (or their components) that have therapeutic effects on AD have been studied. In addition, recent studies on inflammasomes as one component of the innate immune system have been carried out. Additionally, studies on the close relationship between the activation of inflammasomes and toxins in AD have been reported. This review highlights the literature that discusses the pathogenesis of AD, the role of toxins in AD, and the positive and negative effects of toxins on AD. Lastly, suggestions are made regarding the role of inflammasomes in AD. PMID:28025545

    Ginseng and ginsenosides are frequently used in the treatment of chronic inflammatory diseases. Recently, 20-O-β-d-glucopyranosyl-20(S)-protopanaxadiol (GPD), the main metabolite of ginsenosides, was reported to have both anti-allergic and anti-pruritic effects. The immunomodulatory effects of GPD-fortified ginseng extract (GFGE) on atopic dermatitis (AD)-like symptoms in mice were investigated. This study was designed to investigate the preventive effect of GFGE on AD-like symptoms. The effects of orally administered GFGE on Dermatophagoides farinae body extract (DFE)-induced AD-like symptoms in NC/Nga mice were assessed by analyzing dermatitis score, ear thickness, scratching time, skin histological changes, and serum level of macrophage-derived chemokine (MDC). In addition, splenocytes were isolated from the mice and stimulated with anti-CD3 and anti-CD28 monoclonal antibodies to produce cytokines. Oral administration of GFGE significantly attenuated DFE-induced increases in dermatitis score, ear thickness, scratching time, and severity of skin lesions in NC/Nga mice. GFGE treatment also reduced level of MDC in serum, infiltration of eosinophils and mast cells in skin, and production of cytokines in splenocytes. These results suggest that GFGE might ameliorate DFE-induced AD-like symptoms and be an alternative therapeutic agent for the prevention of AD. © 2013 Published by Elsevier Ireland Ltd.

    We herein report a 51-year old man in whom tinea corporis developed within a radiation field while he was receiving X-ray radiation therapy for the squamous cell carcinoma of hypopharynx. At a dose of 23 Gy approximately 10 days after starting radiotherapy, the patient began to complain of a pruritic eruption on the irradiated skin. A physical examination revealed diffuse erythema, and red papules on both sides of the neck. A fungal culture grew Tricophyton rubrum (T. rubrum). The eruption completely resolved after 3 weeks of topical treatment with 1% clotrimazole cream. We next investigated the effect of X-rays on the growth of T. rubrum and the number of Langerhans cells in the epidermis. One hundred Gy of X-rays did not cause any inhibition of growth of T. rubrum. On the other hand, 25 Gy of X-rays markedly reduced the number of epidermal Langerhans cells. These results show that dermatophytes are resistant to X-rays, while epidermal Langerhans cells, which play a crucial role in the skin immune system, are sensitive to it. These are some of the reasons why tinea corporis developed in the above case entirely within the radiation field during X-ray therapy. (author)

    Generalized discoid lupus erythematosus (DLE) is an autoimmune skin disease variant rarely reported in dogs. The antimalarial immunomodulator hydroxychloroquine has been suggested as maintenance therapy for generalized DLE in one dog, but several recurrences were noted in the 1 year follow-up of that patient. To describe the effective treatment of generalized DLE with ciclosporin in one dog. A 6-year-old, castrated male crossbred dog was presented with pruritic, well-demarcated annular to polycyclic, hyperpigmented plaques with marginal erythema on the dorsal head, neck, trunk and medial extremities; these had been nonresponsive to treatment with doxycycline and niacinamide. Investigation included complete blood count, serum chemistry profile, urinalysis, serum antinuclear antibody test, histopathological examination and direct immunofluorescence testing of skin biopsies. The presence of lymphocyte-rich interface dermatitis on histology, together with generalized chronic recurrent hyperpigmented plaques, was consistent with the diagnosis of a generalized variant of DLE. The absence of systemic signs and unremarkable laboratory tests excluded concurrent systemic lupus erythematosus. Treatment was initiated with oral dexamethasone and ciclosporin. After 1 month, dexamethasone was discontinued and oral ketoconazole was added to the therapeutic regimen. Four months later, pruritus and erythema resolved, with most skin lesions becoming impalpable. Over the last 6 months, the patient's DLE was maintained in remission with oral ciclosporin and ketoconazole in combination every 3 days. The combination of ciclosporin and ketoconazole appeared effective to induce and maintain lesion remission in this dog with generalized DLE. © 2014 ESVD and ACVD.

    Macromastia can cause psychiatric disorders, such as anxiety and depression, and decreases in self-esteem and self-confidence. These problems often externalize themselves on the skin, causing lesions characterized by various degrees of excoriations and lichenified plaques. Mammaplasty operations are very effective in the treatment of neurotic excoriations and similar skin lesions as well as any underlying psychiatric disorders. This study included 17 patients with macromastia and neurotic excoriation lesions who underwent psychiatric treatment for various reasons. Follow ups were performed using routine photographs used in breast surgeries. During the postoperative follow ups, the excoriations for nearly every patient healed within 2 weeks. Some lesions healed with atrophic scars and some with permanent hyperpigmentation. Patients' physical complaints, such as backache, shoulder ache and submammary pruritic dermatitis, were also observed to heal. In addition, the patients stated that they felt better psychologically, and most also reported stopping psychiatric treatment. The psychological problems caused by macromastia include neurotic excoriation and similar skin problems, and aesthetic reduction mammaplasty surgeries are very effective in the treatment of these lesions. Body image perception comprises an important part of self-respect and self-esteem, and psychological-status cosmetic surgery can be evaluated as an alternative to psychological treatment.

    Full Text Available Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/ available.

    OBJECTIVE: To devise a flowchart suitable for assessing risk of trichomoniasis, chlamydia and gonorrhoea in an adolescent population, not all of whom will be sexually experienced or currently in a relationship. METHODS: The data used to derive the flowchart were generated from cross-sectional microbiological surveys of girls aged 14-19 years in Port Harcourt, Nigeria. The flowchart screened on the basis of: (i) sexual experience; (ii) recent sexual activity; (iii) a positive urine leukocyte esterase (LE) test; and (iv) among LE negatives, a history of malodorous/pruritic discharge. FINDINGS: Using this flowchart, we found that 26.2% of all adolescents screened would receive treatment for cervicitis and vaginitis. Chlamydial, gonococcal, and trichomonal infections were correctly diagnosed in 37.5%, 66.7%, and 50% of the cases, respectively. CONCLUSION: Although the flowchart is more suitable for an adolescent population than the vaginal discharge algorithm used in syndromic management protocols, it still lacks precision and needs adapting to local settings.

    Full Text Available A twenty year old male presented with purpuric lesions with chronic painful ulcers over the lower extremities and a recurrent pruritic rash on the trunk for 10 years. He was diagnosed as idiopathic leukocytoclastic vasculitis (LCV after investigations failed to reveal a systemic association. He was treated with immunosuppressants at each visit with partial remission. In 2004, he was diagnosed with bronchial asthma and allergic rhinitis. In his recent admission, he showed necrotic ulcers on legs and extensive shiny, truncal micropapules. Examination revealed maxillary sinus tenderness and loss of sensation on the medial aspect of the left lower limb. Biopsy of ulcer and the micropapules showed the presence of extravascular eosinophils, while hematological investigations showed peripheral eosinophilia of 18%, raised serum Immunoglobulin E (IgE, Anti nuclear antibody (ANA positivity and negative antineutrophil cytoplasmic antibody (ANCA. Radiography confirmed maxillary sinusitis, nerve conduction studies revealed mononeuritis of the anterior tibial nerve and pulmonary function tests (PFT were normal. Clinical examination and investigations pointed towards the diagnosis of Churg-Strauss syndrome (CSS. This report highlights the development of full-blown CSS over a period of 12 years in a patient initially diagnosed as idiopathic LCV, emphasizing the need for regular follow-up of resistant and recurrent cases of LCV.

    The diagnosis of canine atopic dermatitis (CAD) remains challenging due to the lack of a simple biomarker or metabolic profile. In human medicine, Fourier transform infrared spectroscopy (FTIR) is an analytical technique used for several diseases. It requires a small amount of sample and allows the identification of structural moieties of biomolecules on the basis of their infrared absorption, with limited sample pretreatment. The aim of the study was to evaluate the diagnostic value of FTIR. Three groups were tested: 21 dogs with non food-induced CAD (NFICAD), 16 dogs with inflammatory conditions of various origins but without allergic dermatoses (OD) and 10 healthy dogs (H). Peripheral blood was collected and spectra were acquired with a FTIR spectrophotometer. A principal component analysis (PCA) was performed on the full wavenumber spectra (4000-600/cm), followed by a Fisher discriminant analysis (DA) to assess the differences between the three groups. The PCA followed by the DA of whole spectra showed significant differences between the three groups. These results suggest that by using the FTIR method, dogs with NFICAD can be differentiated from healthy dogs and dogs with nonallergic inflammation. There was no overlap between the spectral data of the three groups indicating that NFICAD dogs were correctly segregated from the H and OD groups. A study on a larger cohort including common pruritic skin diseases is necessary to confirm these initial results and the relevance of this diagnostic technique. © 2016 ESVD and ACVD.

    The typical manifestations of Penicillium marneffei (nowadays Talaromyces marneffei) infection in children without human immunodeficiency virus (HIV) remain unclear. The current work presents the case of a child without an underlying disease who was infected with P. marneffei comorbid with eosinophilia. A 2-year-old male was infected with P. marneffei. A physical examination revealed a high-grade fever, ulcerated lesions in the oral mucosa, anemia, pruritic erythematous papules on the sac and thigh and watery diarrhea. A chest enhanced computed tomography scan showed multiple small, nodular, high-density shadows in the lungs, multiple lymphadenectasis in the hilum of the lungs and mediastinum, and liquid in the right pleural cavity. The patient's plasma was negative for HIV. Routine blood tests initially indicated that the patient had leucopenia; however, later tests indicated that he had leukocytosis. This peak was caused by a significant increase in eosinophils. The total IgE and specific allergen levels were normal. The stool was negative for parasite eggs. Aspergillus antigen (galactomannan, GM) levels were significantly increased and were present in the serum for a relatively long period. Eosinophilia can occur during P. marneffei infection, and this finding might provide additional information on the activity of this intracellular parasite. In addition, GM detection might be useful for monitoring the effect of antifungal treatments; however, this theory requires more data for verification.

    Full Text Available Introduction: Systemic contact dermatitis (SCD is a systemic reactivation of a previous allergic contact dermatitis. The initial exposure may usually be topical, followed by oral, intravenous or inhalation exposure leading to a systemic hypersensitivity reaction. A case of a 27 year-old male with SCD due to nickel is reported Case Report: A 27 year-old male presented with recurrent pruritic eruption consist of deep seated vesicles on both palmar and left plantar since 6 months before admission. This complaint began after patient consumed excessive amounts of chocolate, canned food, and beans. The patient worked as a technician in a food factory. History of allergy due to nickel was acknowledged since childhood. The clinical presentation was diffuse deep seated vesicles, and multiple erythematous macules to plaques, with collarette scale. Patch test using the European standard showed a +3 result to nickel. The patient was diagnosed as systemic contact dermatitis due to nickel. The treatments were topical corticosteroid and patient education of avoidance of both contact and systemic exposure to nickel. The patient showed clinical improvement after 2 weeks. Discussion: SCD was diagnosed due to the history of massive consumption of food containing nickel in a patient who had initial sensitization to nickel, with clinical features and the patch test result. Advice to be aware of nickel and its avoidance is important in SCD management.

    2017-07-01

    Full Text Available A 48 years old female patient had been suffering from the lesions presented  for four years. They have started as small, pruritic patches which had been mechanically irritated and grew up in time. The patient had no associated comorbidities or allergies, and she was not under any medication. On physical examination, she presented one erythematous, exudative plaque, with dimensions of 2.5/4 cm, located on the proximal phalanx and interphalangeal articulation of the left thumb. All histopathological  features were consistent with the diagnosis of lichen simplex chronicus. Some lesions of lichen simplex chronicus exhibit signs of pseudocarcinomatous, infundibular and sometimes eccrine ductal proliferation of keratinocytes. Although the pseudoinfiltrative aspect of the epithelial proliferation and its pronounced degree might mimic a well-differentiated lesion of squamous cell carcinoma, a lack of cellular atypia and atypical mitotic figures are features that do not support this diagnosis. On the other hand, long lasting lesions of lichen simplex chronicus may lead to alterations in the processes of keratinocyte proliferation and differentiation and eventually give rise to malignant transformation. The best treatment management is a psychodermatological approach, a combination of skin care with psychotherapy, in order to prevent relapses.

  15. Acute and Chronic Urticaria: Evaluation and Treatment.

    Science.gov (United States)

    Schaefer, Paul

    2017-06-01

    Urticaria commonly presents with intensely pruritic wheals, sometimes with edema of the subcutaneous or interstitial tissue. It has a lifetime prevalence of about 20%. Although often self-limited and benign, it can cause significant discomfort, continue for months to years, and uncommonly represent a serious systemic disease or life-threatening allergic reaction. Urticaria is caused by immunoglobulin E- and non-immunoglobulin E-mediated release of histamine and other inflammatory mediators from mast cells and basophils. Diagnosis is made clinically; anaphylaxis must be ruled out. Chronic urticaria is idiopathic in 80% to 90% of cases. Only a limited nonspecific laboratory workup should be considered unless elements of the history or physical examination suggest specific underlying conditions. The mainstay of treatment is avoidance of triggers, if identified. The first-line pharmacotherapy is second-generation H1 antihistamines, which can be titrated to greater than standard doses. First-generation H1 antihistamines, H2 antihistamines, leukotriene receptor antagonists, high-potency antihistamines, and brief corticosteroid bursts may be used as adjunctive treatment. In refractory chronic urticaria, patients can be referred to subspecialists for additional treatments, such as omalizumab or cyclosporine. More than one-half of patients with chronic urticaria will have resolution or improvement of symptoms within a year.

    Chronic urticaria may often be associated with interleukin (IL)-1-mediated autoinflammatory disease, which should be suspected if systemic inflammation signs are present. Here, we report a case of Schnitzler's syndrome without monoclonal gammopathy treated successfully with the IL-1 receptor antagonist anakinra. A 69-year-old man suffered from a pruritic urticarial rash for 12 years. It became aggravated episodically and was accompanied by high fever, arthralgia, leukocytosis, and an elevated C-reactive protein and erythrocyte sedimentation rate. The episodes each lasted for over one week. Neutrophilic and eosinophilic inflammation was found on skin biopsy. However, serum and urine electrophoresis showed no evidence of monoclonal gammopathy. The cutaneous lesions were unresponsive to various kinds of anti-histamines, systemic glucocorticoids, colchicine, cyclosporine, dapsone, and methotrexate, which were administered over a span of 3 years immediately preceding successful treatment. A dramatic response, however, was observed after a daily administration of anakinra. This observation suggests that the correct diagnosis of this case is Schnitzler's syndrome without monoclonal gammopathy. For an adult patient with refractory chronic urticaria and systemic inflammation, Schnitzler's syndrome could be considered as a possible differential diagnosis. Although the typical form of Schnitzler's syndrome exhibits the presence of monoclonal gammopathy as a diagnostic criterion, monoclonal gammopathy may be absent in an atypical form. In such a situation, an IL-1 antagonist should be effective for the management of chronic urticaria. © Copyright: Yonsei University College of Medicine 2018.

    2017-10-01

    Adverse food reaction (AFR) is an important differential diagnosis for the pruritic dog. It is usually diagnosed by feeding an elimination diet with a novel protein and carbohydrate source for eight weeks followed by subsequent food provocation. A previous study demonstrated that patch testing dogs with foods had a high sensitivity and negative predictability for selection of elimination diet ingredients. The aim of this study was to investigate patch testing with proteins, carbohydrates and dry commercial dog food in dogs to determine whether there was value in patch testing to aid the diagnosis of canine adverse food reaction. Twenty five privately owned dogs, with confirmed AFR, underwent provocation trials with selected food antigens and patch testing. For proteins, carbohydrates and dry dog food the sensitivity of patch testing was 100%, 70% and 22.2%, respectively; the negative predictive values of patch testing were 100%, 79% and 72%. The positive predictive values of patch testing for proteins and carbohydrates were 75% and 74%, respectively. This study confirmed that patch testing may be useful for the selection of a suitable protein source for an elimination diet in dogs with suspected AFR, but not as a diagnostic tool for canine AFR. Results for proteins are more reliable than for carbohydrates and the majority of positive patch test reactions were observed with raw protein. Patch testing with commercial dog food does not seem to be useful. © 2017 ESVD and ACVD.

    Pityrosporum folliculitis is an under-recognized eruption of the face and upper portion of the trunk that may be confused with, or occur simultaneously with, acne vulgaris. We sought to characterize risk factors for Pityrosporum folliculitis, its clinical presentation, and its response to treatment. A retrospective chart review was performed on all patients age 0 to 21 years seen at our facility from 2010 to 2015 with Pityrosporum folliculitis confirmed by a potassium hydroxide preparation. Of 110 qualifying patients, more than 75% had acne that had recently been treated with antibiotics, and when recorded, 65% reported pruritus. Clinical examination demonstrated numerous 1- to 2-mm monomorphic papules and pustules that were typically on the forehead extending into the hairline and on the upper portion of the back. The most common treatment was ketoconazole shampoo, which led to improvement or resolution in most cases. Some patients required oral azole antifungals. This study was retrospective and relied on providers describing and interpreting the clinical findings and potassium hydroxide preparations. No standard grading system was used. Unlike classic acne vulgaris, Pityrosporum folliculitis was more common after antibiotic use. It presented as fine monomorphic, pruritic papules and pustules along the hairline and on the upper portion of the back, and it improved with topical or oral azole antifungal therapy.

    Malignant melanoma of the heel is a rare melanoma subtype with incidence rates that reflect the complex relationship between sun exposure at certain geographic locations, individual melanin levels and overall melanoma risk. It is oftentimes characterized by poor prognosis because of delays in presentation resulting in longitudinal tumor invasion, lymph node involvement and metastasis. A 59-year-old woman was admitted to the Eric Williams Medical Sciences Complex, Trinidad and Tobago with a 5mm pruritic lesion on her left heel. At presentation, the lesion was asymmetric with border irregularities, color heterogeneity, with dynamics in elevation and overall size. She was subsequently diagnosed with malignant melanoma with left inguinal lymphadenopathy. A single stage wide local excision (WLE) of the left heel lesion with a split-thickness skin graft (STSG) and a left inguinal lymphadenectomy were performed. Dacarbazine (Bayer) was administered post operatively. Globally, the incidence of malignant melanoma is rapidly increasing, particularly, in countries like Trinidad and Tobago with a significant population of non-fair skinned individuals. There is need for strategic initiatives to increase patient adherence in these populations. The rarity of malignant heel melanomas heightens the need for increased patient awareness and greater clinical surveillance to ensure early diagnosis and treatment. Copyright © 2016 The Authors.

    To gain information on hair loss amongst curly coated retrievers by questionnaire and to define the clinical and pathological features of hair coat abnormalities in affected dogs in the United Kingdom and Sweden. Questionnaires were completed by members of the Curly Coated Retriever Clubs. Fourteen dogs (six in the United Kingdom, eight in Sweden) were clinically examined and skin/hair samples collected for microscopy and histopathology. Blood was collected for haematological, biochemical and endocrine assays. Of 90 dogs surveyed, 39 had current or previous episodes of symmetrical, non-pruritic alopecia and or frizzy coat changes, usually affecting caudal thighs, axillae, dorsum and neck before 18 months of age; 23 dogs had a waxing/waning course. Examined dogs generally matched the pattern described in questionnaires. Hair shaft anomalies comprised occasional distorted anagen bulbs (10 dogs) and transverse fractures (8 dogs). Vertical histopathological sections showed infundibular hyperkeratosis (28 of 30 sections) and low-grade pigment clumping (17 of 30). Subtle telogenisation of hair follicles was unequivocally confirmed by transverse histomorphometric analyses. The follicular dysplasia of curly coated retriever reported here is similar to that of Irish water spaniels and Chesapeake Bay retrievers but distinct from that of Portuguese water dogs. The genetic basis requires further assessment. © 2016 British Small Animal Veterinary Association.

    Recurrent or persistent follicular dysplasia and interface dermatitis are described in nine Boxers. Data on age, sex, seasonality of alopecia and histopathological features of the follicular dysplasia in these nine Boxers are comparable with those described in previous reports. The interface dermatitis was characterized by multifocal annular crusted lesions confined to the areas of follicular dysplasia. The inflammatory lesions were neither pruritic nor painful and affected dogs were otherwise healthy. Histopathologically the clinically inflammatory lesions were characterized as an interface dermatitis. Immunohistochemical studies failed to demonstrate immunoglobulins or complement at the basement membrane zone or within blood vessel walls. In dogs with recurrent or persistent disease, the follicular dysplasia and interface dermatitis ran identical, concurrent courses of spontaneous remission and recurrence, or persistence, respectively. One dog with persistent disease was treated successfully with tetracycline and niacinamide for the interface dermatitis, and melatonin for the follicular dysplasia. Although the aetiopathogenesis of this newly described condition and the relationship between the two histological reaction patterns are not known, photoperiod and genetic predisposition appear to play a role.

    Drug reaction with eosinophilia and systemic symptoms (DRESS) is a hypersensitivity reaction characterized by maculopapular rash, exfoliative dermatitis, lymphadenopathy, fever, eosinophilia, and involvement of internal organs. Evidence for reactivation of herpes family viruses has been observed in some DRESS patients, and activated CD8+ T lymphocytes are largely directed against Epstein-Barr virus. Here, we report two cases complicated with this infection. Both patients received antibiotics and non-steroidal anti-inflammatory drugs. These patients manifested clinically with high fever, facial edema, diffuse pruritic erythroderma and maculopapules over the entire body, purpuric rashes in both lower limbs and lymphadenopathy of cervical and inguinal nodes. Laboratory tests revealed abnormal liver function, blood eosinophils, and ferritin levels. The patients recovered completely; however, the female patient developed hemophagocytic syndrome on the 15th day of illness. She developed new itchy rash, and laboratory tests rapidly worsened with fibrinogen levels dramatically reduced to 0.61 g/L. Bone marrow aspiration revealed an increased number of macrophages with hemophagocytosis and a reversed CD4/CD8 ratio of 0.45. These cases suggest that human herpes virus and coagulation function evaluations are necessary in DRESS patients.

    Lichen planus (LP) is a mucocutaneous inflammatory disease that involves papulosquamous eruption of the skin, scalp, nails, and mucous membranes. This uncommon condition has a higher prevalence in African Americans and females. Women accounts for 50% of cutaneous LP (CLP) and 60% to 75% of oral LP (OLP) cases. Diagnosis is centered around clinical presentation. Patient evaluation requires a comprehensive physical examination to identify any potential sites of involvement. LP is usually described by the "Six P's": planar, purple, polygonal, pruritic, papules, and plaques. Drug-induced LP, or lichenoid drug reactions, is uncommon and usually indiscernible from other forms of LP. Lichenoid drug reactions exhibit parakeratosis, dermal infiltrates of eosinophils, or perivascular lymphocytic infiltrates affecting the reticular dermis. An extended time interval between the initiation of drug to the onset of symptoms usually does not exclude potential diagnosis of a lichenoid drug reaction. We describe a case of hydrochlorothiazide-induced LP without prolonged exposure to sunlight diagnosed in the emergency department (ED). In this case, a pharmacist-conducted medication reconciliation played an integral role in accurately recognizing this adverse drug reaction. Our case report adds to the limited available literature on the topic, most of which originated more than 30 years ago.

    Atopic dermatitis (AD) is a chronic pruritic dermatitis that has unknown aetiology. It seems that Malassezia furfur has a role in pathogenesis of AD. The purpose of this study was to evaluate skin responses to M. furfur antigens in AD patients. Malassezia furfur was grown and the yeasts were broken. Cells were centrifuged and supernatants were used as crude extracts (CE). Protein components of CE were separated by sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE). In addition, to fractionate CE antigens, gel filtration chromatography was performed. One hundred and fifteen AD patients were selected for skin-prick test (SPT). In SDS-PAGE, CE showed a total of 19 different protein bands (10-100 kDa). Chromatographic gel filtration with M. furfur proteins showed four major fractions (F). The protein pattern of F(1) (tube no. 40) was between 22 and 100 kDa and it was selected for SPT. In SPT, 49.6% and 42.6% patients showed positive reactions with CE and F(1) antigens respectively. The most positive results were obtained in 20-29 aged group (P furfur may have a role in AD signs; it is suggested to use F(1) antigens in allergy tests.

    Several studies have been performed to evaluate the efficacy of dietary n-3 fatty acid for patients with renal dysfunction. While about 40% to 80% of patients with end-stage renal disease (ESRD) complain about pruritus and xerosis, there are few reports on the effects of topical n-3 fatty acid on these symptoms. In order to investigate the possible beneficial effects of topical n-3 fatty acid, oils extracted from chia (Salvia hispanica) seed were formulated into topical products, the effects of which were measured. Five healthy volunteers having xerotic pruritus symptoms and 5 patients with pruritus caused by either ESRD or diabetes were involved in this study. A topical formulation containing 4% chia seed oils were applied for an 8-week duration. Subjective itching symptoms were assessed on a 6-point scale, as were other skin functions, namely transepidermal water loss and skin capacitance. After the 8 weeks of application, significant improvements in skin hydration, lichen simplex chronicus, and prurigo nodularis were observed in all patients. A similar improvement was also observed among healthy volunteers with xerotic pruritus. Improvement of epidermal permeability barrier function and skin hydration, represented by trans-epidermal water loss and skin capacitance, respectively, were also observed. No adverse effects were observed in all the tested patients and volunteers. Chia seed oil can be used as an adjuvant moisturizing agent for pruritic skin, including that of ESRD patients.

    To report an incident of a drug-induced exanthem during treatment with dabigatran in a patient without prior exposure to the drug. A 20-year-old white male was prescribed oral dabigatran 150 mg twice daily for thromboembolic prevention because of nonvalvular atrial fibrillation. After 2 weeks of dabigatran therapy, a raised, pruritic, erythematous rash developed on the patient's inner thigh and forearm. Upon discontinuation of dabigatran and initiation of oral corticosteroid treatment, the rash resolved. Dabigatran therapy was not readministered and thromboembolic prevention therapy with warfarin was instituted. The clinical evidence for efficacy of dabigatran was derived largely from the RE-LY trial, which provided an open-label comparison with warfarin for the reduction of stroke and systemic embolism in nonvalvular atrial fibrillation. The most frequent adverse reactions leading to discontinuation of dabigatran were bleeding and gastrointestinal events. In the RE-LY study, drug hyper-sensitivity, allergic edema, anaphylactic reaction, and anaphylactic shock were reported in <0.1% of patients receiving dabigatran. Despite the low incidence of hypersensitivity reported in the RE-LY trial, the use of the Naranjo probability scale indicated a probable relationship between the rash and dabigatran therapy in this patient. Upon initiation of dabigatran therapy, surveillance for hyper-sensitivity reactions should be included as part of routine drug monitoring.

    Full Text Available Cheyletiellosis (cheyletiella dermatitis is a dermatitis caused by cheyletiella mites that are seen more commonly in cats, dogs and rabbits all over the world. Cheyletiella blakei, which is naturally hosted by cats, causes infestations in people, especially who are in close contact with infested cats. The diagnosis of cheyletiellosis in humans is established by the suspicion of physician or veterinarian and demonstration of the mites in cats. If not suspected, cheyletiellosis may be thought as delusions of parasitosis and may be undiagnosed. A 48-year-old woman presented to our clinic with red, pruritic papules on the chest, abdomen, arms and anterior thighs. There was no remission of the complaints of the patient after 3 days of topical corticosteroid treatment. Following more detailed examination and medical history, cheyletiellosis was suspected. The diagnosis was confirmed by a veterinary control of the cat that the women had started feeding at home about 15 days ago. Although cheyletiella dermatitis is not uncommon, most cases are undiagnosed because it is not a well-known dermatosis by dermatologists. As far as we know, there is no previously reported cheyletiella case in our country. (Turk­derm 2011; 45: 213-5

  8. Update on lichen planus and its clinical variants

    2015-08-01

    Full Text Available Lichen planus (LP is an inflammatory skin condition with characteristic clinical and histopathological findings. Classic LP typically presents as pruritic, polygonal, violaceous flat-topped papules and plaques; many variants in morphology and location also exist, including oral, nail, linear, annular, atrophic, hypertrophic, inverse, eruptive, bullous, ulcerative, lichen planus pigmentosus, lichen planopilaris, vulvovaginal, actinic, lichen planus-lupus erythematosus overlap syndrome, and lichen planus pemphigoides. Clinical presentation of the rarer variant lesions may be largely dissimilar to classic LP and therefore difficult to diagnose based solely on clinical examination. However, histopathological examination of LP and LP-variant lesions reveal similar features, aiding in the proper diagnosis of the disease. Management of LP and LP variants aims to control symptoms and to decrease time from onset to resolution; it often involves topical corticosteroids, but varies depending on the severity and location of the lesion. The literature contains an array of reports on the variations in presentation and successful management of LP and its variants. A familiarity with LP and its variants is important in achieving timely recognition and management of the disease.

    Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease usually with a neutrophil rich inflammatory infiltrate, and characterized by linear IgA deposition at the basement membrane zone (BMZ), and neutrophil predominant dermal inflammation. We report a case of LABD with numerous eosinophils and flame figure formation, a unique histopathologic finding not previously reported. A 69-year-old woman presented with a rapidly progressive, intensely pruritic rash over forearms, breasts, axillae, hips, and thighs. Thelesions were comprised of annular vesicles and bullae with hemorrhagic crusts and erosions. The clinical differential diagnosis included bullous pemphigoid(BP), LABD, and epidermolysis bullosa aquisita (EBA). A biopsy from a bullous plaque on the wrist revealed a subepidermal blister with neutrophils and numerous eosinophils with flame figure formation.Direct immunofluorescent (DIF) microscopy revealed linear deposition of IgA at the BMZ. Although unusual, the combined findings supported a diagnosis of LABD. Increased eosinophils may be associated with drug-induced LABD and may explain the numerous eosinophils in our case. It is important to be aware of this finding as the pathology may easily be misdiagnosed as BP, or possibly bullousWells syndrome. This case emphasizes that combined clinical, pathologic, and DIF findings are essential in the diagnosis of bullous dermatoses.

    In this article, we present a literature review of the most popular and commonly used therapeutic procedures belonging to complementary and alternative medicine, which is part of the modern concept of integrative medicine, used in the treatment of psoriasis. Psoriasis is a chronic, systemic, inflammatory disease wherein skin changes are the most visible sign. It occurs in approximately 1% to 3% of the world population, and the National Psoriasis Foundation of the United States estimates the number of patients in the whole world at about 125 million. Psoriasis primarily affects the skin, burdening patients with inflamed, pruritic, and sometimes painful lesions covered with whitish scales that last for years. Because of its prevalence in the general population, diversity of the clinical picture (from minimal and localized lesions without subjective symptoms to life-threatening conditions), and disease duration (practically a lifetime), psoriasis is a disease that has become a focus of modern medicine, and therapeutic options for the treatment of psoriasis are currently very numerous and diverse. Conventional treatment of psoriasis is guided by the so-called principle of "steps," where treatment options are applied according to the severity of illness assessed by a physician. Apart from the official therapy for psoriasis, as it is defined and understood in modern developed societies, there exists in parallel a great number of traditional, complementary, and alternative psoriasis treatments, which are based on the beliefs, experiences, and theories inherent to different cultures; in this article, we have analyzed the literature related to some of these procedures.

  11. Pruritus in psoriasis: An update.

    Szepietowski, J C; Reich, A

    2016-01-01

    Psoriasis is one of the most common chronic inflammatory skin diseases, found in about 1-3% of the general population. Pruritus affects about 60-90% of patients with psoriasis. The aim of this review was to summarize current knowledge about the pathogenesis and treatment of this symptom in psoriasis patients. Majority of psoriatic patients consider pruritus as the most bothersome symptom. The pathogenesis of pruritus is still unknown but the major concept of its origin is focused on neurogenic inflammation. Possible itch mediators include neuropeptides released from dermal nerve endings upon various stimuli, which were found to be abnormally expressed in itchy psoriatic plaques. Another important phenomenon supporting the idea of neurogenic inflammation as a key player in pruritus accompanying psoriasis is abnormal innervations of psoriatic skin. Possibly increased innervation density in psoriasis may decrease the threshold for pruritic stimuli. It is also suggested that pruritus in psoriasis might be related to abnormal functioning of the peripheral opioid system. Despite the high frequency of pruritus in psoriasis, to date there is no single antipruritic therapy dedicated specifically to treat itch in this disease. Neurogenic inflammation seems to be important for itchiness in psoriasis. Treatment of pruritus in patients with psoriasis should be directed towards the resolution of skin lesions, as disease remission usually is linked with pruritus relief. © 2015 European Pain Federation - EFIC®

    Here, we review the human botfly (Dermatobia hominis), which belongs to a group of Diptera generically known as "myiasis-causing flies," characterized by the ability of their larvae to develop in animal flesh. In addition to its medical and economic importance, there is an academic interest in this botfly because of its peculiar biology, particularly because a phoretic diptera is needed to complete the life cycle. The larvae penetrate the host's skin, causing furuncle-like lesions that are pruritic, painful, and resemble subcutaneous nodules, producing irreversible perforations in the skin. Although D. hominis is distributed from Mexico to Argentina, a review performed by our working group from 1999 to 2015 determined that the countries with the highest infection rates in travelers are Belize, Bolivia, and Brazil. Interestingly, infected men show a higher variation in the distribution of the lesions than in women. Many treatment schemes have been suggested, including the application of highly dense liquids to the lesion to cause anoxia in the D. hominis larvae. We showed, for the first time, a Bayesian inference between D. hominis and other myiasis-causing flies. The flies grouped into two main clusters according to their capacity to produce facultative and obligatory myiasis, and D. hominis was phylogenetically close to Cuterebra spp. © 2016 The International Society of Dermatology.

    Myiasis is the parasitism of organs and tissues of warm-blooded vertebrates by flies larvae. D hominis is a flie geographically restricted to tropical America from Mexico to northern Argentina. The adult flie, which is not hematophagous, needs to put its eggs on the abdominal surface of hematophagous arthropods which serve as carriers of future larvae which are deposited on the skin of the hosts (mammals, birds and accidentally men) when biting. Seven patients (two females) aged 7 to 35 years old, of different nationalities, recalled receiving mosquito bites, after staying in tropical American areas in the previous forty days. They presented furuncle-like lesions in exposed surfaces of the body. These lesions, 2-3 cm long, pruritic and mildly tender, broke and released a serous or serohematic fluid. Through the resulting opening, it was possible to partially observe the larva. Larvae were extracted by manual pressure (4) or surgical incision (3) and identified as D hominis larvae. Diagnosis of dermatobiasis, an imported myiasis, must be based on the characteristics of lesions and the previous residence in endemic areas of America.

  14. Arthropod bites.

    The phylum Arthropoda includes arachnids and insects. Although their bites typically cause only local reactions, some species are venomous or transmit disease. The two medically important spiders in the United States are widow spiders (Latrodectus), the bite of which causes intense muscle spasms, and the brown recluse (Loxosceles), which may cause skin necrosis. Widow bites usually respond to narcotics, benzodiazepines, or, when necessary, antivenom. Most recluse bites resolve uneventfully without aggressive therapy and require only wound care and minor debridement. Tick bites can transmit diseases only after prolonged attachment to the host. Treatment of clothing with permethrin and proper tick removal greatly reduce the risk of infection. Ticks of medical importance in the United States include the black-legged tick, the Lone Star tick, and the American dog tick. The prophylactic use of a single dose of doxycycline for Lyme disease may be justified in high-risk areas of the country when an attached, engorged black-legged tick is removed. Bites from fleas, bedbugs, biting flies, and mosquitoes present as nonspecific pruritic pink papules, but the history and location of the bite can assist with diagnosis. Flea bites are usually on ankles, whereas mosquito bites are on exposed skin, and chigger bites tend to be along the sock and belt lines. Antihistamines are usually the only treatment required for insect bites; however, severe mosquito reactions (skeeter syndrome) may require prednisone. Applying insect repellent containing diethyltoluamide (DEET) 10% to 35% or picaridin 20% is the best method for preventing bites.

    Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease. It represents one of the symptoms of atopic diathesis. DA affects usually infants and children. aim : The aim of our study is to draw up the epidemiological, clinical features, treatment and outcome of severe childhood AD through a hospital series. methods: A retrospective study of 24 cases of severe childhood AD hospitalized in the Dermatology Department of La Rabta hospital of Tunis was conducted during a 28 year-period (1981 - 2009). results: The hospital incidence of severe childhood AD was 0,085‰. Patient's mean age at the beginning was 14 months. The sex ratio H/F was 1.66. Cutaneous manifestations occurred preferentially in face (75%). Generalized eczema was observed in 37.5% of cases. Pruritus and xerosis were constant. The mean duration of hospitalization was 11 days. Topical corticosteroids was the most effective method of treating severe DA, associated with antiseptic solutions emollient and antihistaminic drugs. Infectious complications were noted in 50% of cases. Ocular complications were observed in 16.7% of cases. Recurrences were reported in 9 cases. Conclusion :AD is an inflammatory, chronically relapsing, and pruritic skin disorder developing in a xerotic skin. Severe AD in childhood is rare in Tunisia. It requires a good understanding of therapeutic modalities by the patient and his family. It is a cause of important morbidity and it may have a bad impact on quality of life.

    Adult-onset Still disease (AOSD) is a rare autoinflammatory syndrome characterized by recurring fevers, arthralgia, and consistent laboratory abnormalities that include leukocytosis and hyperferritinemia. Skin findings accompany the disease in nearly 90% of the cases. Early reports described evanescent, pruritic, salmon-pink or urticarial lesions, referred to as the typical eruption of AOSD. Histopathologic findings consist of superficial perivascular dermatitis with varying number of interstitial neutrophils. Later reports described a more persistent rash that tended to be photodistributed, hyperpigmented, often in a linear configuration, sometimes in a rippled pattern, referred to as the atypical eruption of AOSD. The presence of individual necrotic keratinocytes in the upper spinous layer has been the consistent histopathologic finding. The persistent rash may not represent an atypical presentation of AOSD as recent reports indicate a high prevalence of the rash. Emerging data also suggest that patients with persistent eruption have a worse prognosis. The recognition of the clinical and histopathological findings of skin eruptions of AOSD may facilitate an earlier diagnosis, potentially improving disease outcome. Herein, clinical and histopathological features of cutaneous manifestation of AOSD in 2 Asian women are highlighted accompanied by a relevant review of the disease. © 2017 John Wiley & Sons A/S.

    Lichen planus follicularis tumidus (LPFT) represents an uncommon variety of lichen planus (LP). Clinically, it presents with prominent purplish lesions or white-pigmented yellowish cysts and comedones. Histopathologically, it is similar to lichen planopilaris, and it is additionally characterized by follicles and cysts surrounded by a lichenoid lymphocytic infiltrate. The most common location is the retroauricular region, and it may be associated with other variants of LP. Herein, we describe the case of a 50-year-old woman with a history of lower limb hypertrophic LP who subsequently presented with multiple pink, tumid, pruritic plaques with white-yellow cysts and comedones extensively affecting the bilateral face. Histopathologic examination revealed a lichenoid infiltrate surrounding the follicles and cysts. We diagnosed LPFT and began treatment with topical corticosteroids, antihistamines, systemic corticosteroids and oral acitretin without improvement. Subsequently, the patient had an acceptable response to cyclosporine at doses of 5 mg/kg/day with remission of itching and tumidity but with residual cysts and comedones remaining. To date, the literature contains only 16 cases of LPFT. To our knowledge, this is the most severe case and is the only one with cessation of disease activity in response to cyclosporine. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A carbuncle usually presents as a deep-seated mass of fistulous tracts between infected hair follicles. We present a case in which what appeared to be an inflamed, benign neoplasm turned out to be a very unusual presentation for this condition, the first we could find in the literature. A 62-year-old woman presented with a bothersome 'mole' on her flank of uncertain duration but it was initially pruritic and irritated by her clothing. Owing to the pain, she wanted its removal. A 1 cm soft, pink, stalked papule revealed multiple, closed,, comedo-like spots on its surface (Fig. 1). The lesion was mildly tender and freely mobile on a broad-based stalk. A pre-biopsy diagnosis of irritated intradermal nevus or neurofibroma was made, and the lesion was blade-shaved flush with the skin surface. Histologically, the papule demonstrated small abscesses which seemed to connect, as well as foci of granulation tissue and marked dermal edema (Fig. 2). Fragments of infundibular epidermis were found throughout the lesion. No residual melanocytic or neural neoplasms were identified.

    Full Text Available A 30-year-old Iban woman presented to a rural primary healthcare clinic located along the Batang Rejang in Sarawak. She had a 2-day history of rash, which started over her trunk and later spread to her face and limbs. What started out as individual erythematous maculopapular spots later coalesced to form larger raised blotches. The rash was extremely pruritic and affected her sleep, and hence her visit. The rash was preceded by high grade, persistent fever that was temporarily relieved by paracetamol. She also complained of malaise, arthralgia and myalgia. Her appetite had been poor since the onset of the fever. She lived in a long house at the edge of the jungle. Although she did not have a history of going into the jungle to forage, she went regularly to the river to wash clothes. Clinically, she appeared lethargic and had bilateral conjunctival injection. Her left anterior cervical lymph nodes were palpable. There were erythematous macules measuring 5 to 15 mm distributed over her whole body but predominantly over the chest and abdominal region (Figure 1. An unusual skin lesion was discovered at the right hypochondriac region. This lesion resembled a cigarette burn with a necrotic centre (Figure 2. There was no evidence of hepato-splenomegaly. Examination of the other systems was unremarkable. On further questioning, the patient admitted being bitten by a ‘kutu babi’ or mite 3 days before the onset of her fever.

    Hereditary angioedema is a disease which manifests itself with episodes of spontaneous edema on skin, mucosal and airway. Treatment includes acute and prophylactic approach to minimize the attacks and severity. In many parts of the world, androgen derivatives, antifibrinolytic and fresh frozen plasma are the therapies available for prophylaxis. 16 years old teenager of without history of immune decease, has in the course of 1-year repetitive episodes of painless, non-pruritic angioedema, does not respond to antihistamine therapy, corticosteroids or adrenaline; fresh frozen plasma is applied in 1 occasion exacerbating episode with severity. The diagnosis is delayed because of the unavailability of the study in the country, so it is shipped abroad confirming the deficit of C1 Inhibitor (7.1 μg/mL). Initiating prophylactic therapy with Danazol, with subsequent episodes decreased. The delay diagnosis involves considerable risk in these patients; the importance of long-term prophylactic treatment is ratified in the use of androgens, being as an available option in developing countries.

AD long-term treatment is usually required to control and prevent flares, and patients need a treatment that is safe and efficacious when applied continuously or intermittently over a prolonged period of time. The treatment options should be chosen according to age, clinical features and severity of the disease in every single patient. For the treatment of a chronic disease like AD, sustained tolerability and efficacy of the applied medications are essential. A topical immunomodulator, tacrolimus ointment, provides an alternative to topical corticosteroids without the associated adverse events. Tacrolimus is a macrolide lactone with unique immunomodulatory properties and strong anti-inflammatory activities and can be used without increasing the risk of infection or other non-application site adverse events, and without loss of effectiveness, in patients with AD.Keywords: atopic dermatitis, tacrolimus, safety

    Full Text Available Radiation-induced morphea (RIM is a rare and underrecognized complication of radiation therapy that most commonly occurs in women after treatment for breast cancer. Although not fully understood, RIM is hypothesized to arise from an increase in cytokines that stimulate collagen production and extracellular matrix formation. Most documented cases of RIM occur 1 year after radiation therapy and are localized to areas that were treated for breast cancer. We report on a case of a female patient with stage IB endometrial adenocarcinoma who was treated with 24 Gray of adjuvant brachytherapy. The patient developed a diffuse morpheaform, pruritic eruption only at distant sites from the brachytherapy treatment field. Although treatment for RIM is generally unsatisfactory, our patient experienced improvement in the pruritus and a regression of the lesions while applying topical 0.1% tacrolimus ointment and 0.1% triamcinolone creme. An early diagnosis of RIM can prevent extensive workup, guide treatment, and improve quality of life for patients. Keywords: radiation-induced morphea, postirradiation morphea

    We report the unprecedented case of reactive eccrine syringofibroadenoma (ESFA) secondary to primary cutaneous amyloidosis. A 62-year-old woman of Asian ethnicity presented with a pruritic rash on the back of long-standing duration. Physical examination revealed diffuse hyperpigmentation localized to the interscapular region; there were a multitude of hyperpigmented macules merged in a rippled pattern intermixed with scattered papules and cobblestone-like areas. A punch biopsy from a papule was taken. Histopathological examination revealed a network of epithelial strands and cords hanging from the epidermis and harboring foci of ductal differentiation. Eosinophilic collections of amorphous material were found between the epithelial strands, obscuring the superficial dermis. The microscopic picture was consistent with primary cutaneous amyloidosis associated with reactive ESFA. Results of histochemical and immunohistochemical staining confirmed the diagnosis. We speculate that pathogenetic mechanisms intrinsic to primary cutaneous amyloidosis, in addition to unknown genetic factors, resulted in clinical changes of lichen amyloidosus associated with an abnormal hyperplastic epithelial response with histopathological features of ESFA rather than the common epidermal change of acanthosis and hyperkeratosis. © 2013 John Wiley & Sons A/S.

    Lawrence Livermore National Laboratory (LLNL), in collaboration with the Department of Homeland Security (DHS) and the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Services (APHIS) has developed advanced rapid diagnostics that may be used within the National Animal Health Laboratory Network (NAHLN), the National Veterinary Services Laboratory (Ames, Iowa) and the Plum Island Animal Disease Center (PIADC). This effort has the potential to improve our nation's ability to discriminate between foreign animal diseases and those that are endemic using a single assay, thereby increasing our ability to protect animal populations of high economic importance in the United States. Under 2005 DHS funding we have developed multiplexed (MUX) nucleic-acid-based PCR assays that combine foot-and-mouth disease virus (FMDV) detection with rule-out tests for two other foreign animal diseases Vesicular Exanthema of Swine (VESV) and Swine Vesicular Disease (SVD) and four other domestic viral diseases Bovine Viral Diarrhea Virus (BVDV), Bovine Herpes Virus 1 (BHV-1 or Infectious Bovine Rhinotracheitus IBR), Bluetongue virus (BTV) and Parapox virus complex (which includes Bovine Papular Stomatitis Virus BPSV, Orf of sheep, and Pseudocowpox). Under 2006 funding we have developed a Multiplexed PCR [MUX] porcine assay for detection of FMDV with rule out tests for VESV and SVD foreign animal diseases in addition to one other domestic vesicular animal disease vesicular stomatitis virus (VSV) and one domestic animal disease of swine porcine reproductive and respiratory syndrome (PRRS). We have also developed a MUX bovine assay for detection of FMDV with rule out tests for the two bovine foreign animal diseases malignant catarrhal fever (MCF), rinderpest virus (RPV) and the domestic diseases vesicular stomatitis virus (VSV), bovine viral diarrhea virus (BVDV), infectious bovine rhinotracheitus virus (BHV-1), bluetongue virus (BTV), and the Parapox

    Invasive mycoses are an important cause of illness and death in immunocompromised patients. Infections with molds other than aspergilli have been increasingly seen in patients with hematologic cancers, but epidemics of these infections have not yet been reported. To describe an outbreak of invasive mycoses with Paecilomyces lilacinus in severely neutropenic patients. An outbreak investigation. The hematology-oncology isolation and bone marrow transplantation unit of the University Hospital, Basel, Switzerland. 25 consecutive patients admitted between 17 August 1993 (the date of the first manifestation of P. lilacinus infection) and 31 October 1993 (when the unit was closed). Clinical and microbiological data, including histologic findings; cultures from several patient sites; and environmental examinations of potential airborne, parenteral, enteric, and horizontal routes of transmission. Infections were defined by the isolation of P. lilacinus from clinically evident skin eruptions. 12 of the 25 patients (48%) were infected or colonized. Nine patients (36%), including all bone marrow transplant recipients, had documented invasive P. lilacinus infections. All 9 infected patients had papular, pustular, or necrotic skin eruptions. Two patients with severe graft-versus-host disease died with refractory fungal disease; 1 also had microbiologically documented endophthalmitis and kidney infiltrates. Seven affected patients no longer had P. lilacinus after recovery of bone marrow function. The organism was resistant in vitro to amphotericin B, itraconazole, and fluconazole. Patients did not respond clinically to these agents. The outbreak was ultimately traced to a contaminated, commercially available, pharmaceutically prepared skin lotion. The outbreak ended after the skin lotion was recalled and has not recurred after a follow-up period of 2 years. Contaminated skin lotion is a potential cause of opportunistic fungal infections in immunocompromised hosts. Paecilomyces

  7. Differential diagnosis of facial acne on black skin.

    The diagnosis of acne is usually easy, but there are some pitfalls to be avoided. 'Keloid acne of the neck' and beard folliculitis are not acnes in the usual sense: both are inflammatory and fibrous reactions of the hair follicles and frizzy hair; no retentional lesions, blackheads and microcysts--are visible. Gram negative folliculitis classically occurs in acneic male subjects who have undergone extensive treatment with general antibiotics or local antiseptics, but 'de novo' cases do exist. On black skin, this condition is not exceptional, it occurs in both sexes and usually takes the nodular form. The diagnosis should be considered if there is any aggravation of acne which is resistant to classic treatment, with painful nodules on the cheeks. Treatment is based on appropriate antibiotherapy for several weeks and possibly, in a second phase, on Isotretinoin. Pityrosporum folliculitis occurs mainly on the trunk. More frequent in men than in women, it is chiefly observed in subjects living in a hot, humid climate. Demodicidosis is manifested by outbreaks of papular or papulopustular lesions of the face. On black skin the principal differential diagnosis is acne. The presence of numerous parasites is necessary for diagnosis. Clinically speaking, an important sign is when the eyelids are affected. Ivermectin is effective. Acneiform dermatitis may be induced by depigmenting preparations containing powerful dermocorticoids. It is therefore important, in cases of very inflammatory acne, to look for the other clinical signs of voluntary depigmentation. In countries where it is endemic, lepromatous leprosy should be considered. Other common dermatitis may simulate acne or else be associated with it, such as eruptive hidradenoma or molluscum contagiosum. Analysis of the different elementary lesions and the absence of retentional lesions generally enable a diagnosis to be established. © 2012 The International Society of Dermatology.

    Full Text Available Acne conglobata (AC, perifolliculitis capitis abscedens et suffodiens (PCAS and hidradenitis suppurativa (HS are uncommon refractory chronic, inflammatory, scarring diseases but cause serious damage to the quality of life. These three diseases are associated with follicular occlusion. Several studies indicated topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT improved follicular occlusion besides acne treatment. So we attempted to apply ALA-PDT to medicine resistant AC, PCAS and HS. Topical ALA-PDT was applied to 10 patients with AC, seven patients with PCAS and three patients with HS for more than three sessions. All the patients completed the dermatology life quality index (DLQI questionnaire and were assessed for the efficacy at the baseline and on two weeks after each treatment. Adverse effects were recorded at each visit. The results showed 25.5% (5/20, two cases of AC and three cases of PCAS of patients achieved excellent improvement after three sessions of PDT and another 60.0% (12/20, eight cases of AC and four cases of PCAS of patients achieved good improvement. 15.0% (3/20, three cases of HS got poor response (< 20% lesions clearance. Another five cases (three cases of AC and two cases of PCAS also achieved excellent response after 5–7 sessions of PDT. We also found that papular/nodular, cyst/abscess showed higher clearance rate than sinus/fistula (88.5%, 86.1% versus 11.1%. DLQI was reduced after three sessions of PDT in AC and PCAS patients rather than HS patients. 5-ALA-PDT could improve refractory AC and PCAS but could not lead to improvement in late stage of HS. The efficacy increased with more treatment sessions.

    Although skin diseases are associated with low rate of hospitalization, dermatological manifestations are frequent in hospitalized patients. The aim of the study was to describe the inpatient dermatological consultations in a pediatric teaching hospital. Recorded data from inpatient pediatric dermatology consultation requests on a total of 539 consecutive inpatients (aged 0-18 years) from January 2004 to April 2010 were analyzed for consult diagnosis, dermatological disease group, primary diagnosis, requesting department, diagnostic pattern, treatment modality and referral to another department. Of the 539 inpatients, 310 (57.51%) were males and 229 (42.49%) were females. The most frequent requesting department was general pediatrics (37.5%) followed by oncology (15.6%) and pediatric surgery (11.1%). Most of the patients (32.1%) had been hospitalized for dermatological or related disease followed by acute lymphoblastic leukemia (4.1%), chronic renal failure (2.6%), bronchopneumonia (2.6%) and epilepsy (2.4%). Allergic skin diseases (47.1%) were the leading group of dermatoses, which were followed by infectious diseases (14.7%), and systemic diseases with cutaneous manifestations (10.2%). Atopic dermatitis (7.4%) and unclassified eczema (7.4%) were the most frequent dermatoses followed by papular urticaria (5.4%). Most of the patients (80.0%) had diagnosis on clinical basis, whereas skin biopsy was performed in 15.9% and laboratory investigation in 4.1% of the patients. Local treatment was applied to 50.8% of the patients, systemic treatment to 5.8%, local and systemic treatment together to 31.0% while no treatment was given to 11.1%. Only 1.9% of the patients were referred to another department. This study provided important data on the spectrum of skin disorders and their management in pediatric inpatients from the consultation perspective in a pediatric teaching hospital with multispecialty clinics.

    To explain the accumulation of 18 F-2-deoxy-2-fluoro-glucose ( 18 FDG) on positron emission tomography (PET) in the stomach and differences in its pattern, we focus on the accumulation pattern in association with endoscopic findings of the gastric mucosa and Helicobacter pylori (Hp) infection. Of 599 cases undergoing 18 FDG-PET examinations, we retrospectively analyzed the pattern of 18 FDG accumulation in the stomach, findings of upper gastrointestinal endoscopy, and Hp infection. The pattern of 18 FDG accumulation was classified into three groups: localized accumulation only in the fornix (Group A, 32 patients), diffuse accumulation throughout the entire stomach (Group B, 49 patients), and no accumulation (Group C, 191 patients). Regarding the relation between Hp infection and 18 FDG accumulation, Hp infection was positive in 56.3% of Group A, 73.5% of Group B, and 24.1% of Group C, with significant differences (p 18 FDG accumulation and gastric mucosal inflammation, when Groups A and B were compared with Group C, nearly half of the cases in the former groups had papular redness with a significantly higher frequency of redness and erosion. Three cases found to have malignant tumor were limited to the former groups. One mucosa-associated lymphoid tissue (MALT) lymphoma case was also found in the same group. Accumulation of 18 FDG largely corresponded to mucosal inflammation including superficial gastritis and erosive gastritis, and therefore the main cause of non-specific 18 FDG accumulation was considered to be inflammatory mucosa (mainly redness). The accumulation pattern was not associated with atrophic changes of the gastric mucosa or with Hp infection, but with mucosal inflammatory changes, including redness and erosion localized to the fornix. Accumulation of 18 FDG in the stomach suggests a high probability of the presence of inflammatory change in the gastric mucosa forming a background for the development of cancer or malignant lymphoma, and thus requires

    Full Text Available Abstract Background Determinants of the clinical presentation of the leishmaniases are poorly understood but Leishmania species and strain differences are important. To examine the relationship between clinical presentation, species and isoenzyme polymorphisms, 56 Leishmania isolates from distinct presentations of American tegumentary leishmaniasis (ATL from Ecuador were analyzed. Methods Isolates were characterized by multilocus enzyme electrophoresis for polymorphisms of 11 isoenzymes. Patients were infected in four different ecologic regions: highland and lowland jungle of the Pacific coast, Amazonian lowlands and Andean highlands. Results Six Leishmania species constituting 21 zymodemes were identified: L. (Viannia panamensis (21 isolates, 7 zymodemes, L. (V. guyanensis (7 isolates, 4 zymodemes, L. (V. braziliensis (5 isolates, 3 zymodemes, L. (Leishmania mexicana (11 isolates, 4 zymodemes, L. (L. amazonensis (10 isolates, 2 zymodemes and L. (L. major (2 isolates, 1 zymodeme. L. panamensis was the species most frequently identified in the Pacific region and was associated with several clinical variants of cutaneous disease (CL; eight cases of leishmaniasis recidiva cutis (LRC found in the Pacific highlands were associated with 3 zymodemes of this species. Mucocutaneous leishmaniasis found only in the Amazonian focus was associated with 3 zymodemes of L. braziliensis. The papular variant of CL, Uta, found in the Andean highlands was related predominantly with a single zymodeme of L. mexicana. Conclusion Our data show a high degree of phenotypic variation within species, and some evidence for associations between specific variants of ATL (i.e. Uta and LRC and specific Leishmania zymodemes. This study further defines the geographic distribution of Leishmania species and clinical variants of ATL in Ecuador.

    The HIV/AIDS epidemic in Cambodia has become a major problem in the last 7-8 years, mainly because in this formerly war-stricken country the socioeconomic situation is only slowly improving. Since only very few studies have been published to date on the oral health status of Cambodian HIV/AIDS patients, it was the purpose of the present investigation to study oral manifestations in Cambodian patients with HIV disease. One hundred one Cambodian patients with HIV infection or AIDS were examined for the presence of oral manifestations in one medical center in Phomh Penh, Cambodia. Sixty-three men and 38 women with a median age of 32 years were examined (age range 7.5-63.5 years). Of these patients, 42.6% were smokers, 46.5% of men were heavy drinkers and 90.5% of men were promiscuous compared with 5.3% of women. The most frequent AIDS-defining diseases were wasting syndrome (54.5%), Pneumocystis carinii pneumonia (PcP) (19.8%) and tuberculosis (18.8%). Puritic papular eruption, a common cutaneous manifestation in HIV-infected patients, was seen in 17.8% of patients. Candida-associated infections of the oral cavity were most common. Among the patients, 52.5% revealed pseudomembranous candidiasis and 35.6% had bilateral hairy leukoplakia. Only 10% of patients had no oral lesions. Also common were necrotising ulcerative gingivo-periodontal diseases (27.7%). The general health status of 101 Cambodian patients with HIV infection and AIDS was poor, and they demonstrated a large number of oral manifestations. Antiretroviral therapy is presently not available and only a fraction of patients receives antimycotic treatment (25.7%). HIV infection and the AIDS epidemic in Cambodia have become a serious problem and patients urgently need adequate diagnosis and antiretroviral therapies.

    Full Text Available The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices. The incidence of syphilis has increased by 15% in the last 6 years in the United States, with similar increases worldwide. Herein, we present an atypical case of syphilis presenting with severe septic shock and multiple anogenital lesions in an immunocompetent host. A 22-year-old male with no significant past medical history presented with fevers, chills, sore throat, diaphoresis, and diarrhea. He was febrile, tachycardic, hypotensive, and unresponsive to fluid resuscitation requiring short-term vasopressor support. Physical exam revealed diffuse lymphadenopathy; lower extremity macular rash involving the soles of the feet; papular non-pustular lesions on the scrotum; and a 0.5 cm non-tender irregular, healing lesion on the shaft of the penis. Laboratory analysis was significant for leukocytosis and elevated creatinine. Serum screening rapid plasma reagin was positive, and further testing revealed a titer of 1:32, with confirmation via fluorescent treponemal antibody absorption test. The patient was diagnosed with secondary syphilis, which was determined to be the underlying etiology of the sepsis as all other serological evaluations were negative. He was treated with penicillin G benzathine 2.4 million units intramuscular and supportive management, with improvement of symptoms. The patient engaged in high-risk sexual behaviors, including prior unprotected sexual contact with males. New research indicates that up to one-third of patients may present with atypical cutaneous manifestations, as demonstrated by this patient. It is important for physicians to familiarize themselves with the varied clinical presentations of syphilis, which include multiple anogenital lesions and tender primary lesions in primary or secondary syphilis.

    Serratia marcescens is a Gram-negative bacillus belonging to the Enterobacteriaceae family. Because of increasing reports of antimicrobial resistance, this bacterium has received considerable attention and has emerged as an important pathogen. In order to reveal clinical and microbiological characteristics of S. marcescens cutaneous infection and to suggest appropriate antibiotic treatment, we retrospectively analyzed 17 strains isolated from wound swabs of Korean patients between November 2005 and March 2014. A total of 13 patients (five men and eight women) were included in our study, with a mean age of 46.3 years (range, 21-82). Based on medical history, seven patients were classified as immunocompromised. Prior predisposing factors for infections were noted in 12 patients, including pre-existing leg ulcers or dermatitis (5/13), preceding cancer surgeries (2/13), plastic surgeries and filler injection (2/13), traumas (2/13) and medical procedures following cutaneous abscess (1/13). Cutaneous infections showed various clinical presentations, including spontaneous dermal abscess, fingernail change, painful nodules and papular erosions. We found that third- and fourth-generation cephalosporins, gentamicin, levofloxacin and meropenem appeared active against all 17 strains in vitro. Clinically, all patients treated with empirical first-generation cephalosporin showed treatment resistance, and oral quinolone monotherapy was the most preferred antibiotic regimen without treatment failure, with an average treatment duration of 25 days (range, 14-42). This study demonstrates the various clinical presentations and treatment responses for cutaneous S. marcescens infection. Moreover, we suggest that initial antibiotic coverage should be broad enough to account for multidrug resistance in this rare pathogen. © 2015 Japanese Dermatological Association.

    Neutropenic patients developing acute disseminated candidiasis may present with skin lesions. To evaluate the epidemiology of acute disseminated candidiasis with skin lesions in neutropenic patients, taking into consideration changes caused by different prophylactic strategies. A systematic review of English-language articles found via PubMed (1963-2016) was performed. We asked the following questions: (a) What Candida species are more frequently involved in this syndrome? (b) Has antifungal prophylaxis changed the species causing skin lesions? (c) What are the typical patterns of skin lesions? (d) What is the frequency of skin lesions in neutropenic patients with candidaemia or acute disseminated candidiasis? (e) Has antifungal prophylaxis decreased the incidence of acute disseminated candidiasis with skin lesions? Among 183 studies, 33 were selected, reporting 100 cases of acute disseminated candidiasis with skin lesions in neutropenic patients. It occurred more frequently in the setting of induction therapy for de novo or relapsed acute leukaemia, and the most frequent Candida species were C. tropicalis (68%) and C. krusei (15%). Diffuse maculopapular lesions predominated in cases caused by C. tropicalis and nodular and papular lesions in cases caused by C. krusei. Prophylaxis with fluconazole was reported in six cases, C. krusei in five and C. ciferrii in one. The death rate was 45.4%. Two patterns were recognized: disseminated maculopapular lesions caused by C. tropicalis in patients not receiving fluconazole prophylaxis, occurring in 39% to 44% of neutropenic patients with acute disseminated candidiasis, and nodular lesions caused by C. krusei in patients receiving fluconazole prophylaxis, occurring less frequently.

    Rowell syndrome is defined as the association between lupus erythematosus, erythema multiforme-like lesions and characteristic immunological changes including positive tests for rheumatoid factor, speckled antinuclear antibody, positive anti-Ro or anti-La antibodies. The present report presents the case of a 45-year-old female patient who was previously diagnosed in January 2010 with terbinafine-induced subacute cutaneous lupus erythematosus and was admitted for a skin eruption consisting of erythematous-papular erythema multiforme-like lesions, primarily on the trunk and limbs. The associated symptoms consisted of fatigability, myalgia and gonalgia. In October 2015, the illness reoccurred ~1 week after the initiation of Helicobacter pylori eradication treatment. Anti-Ro antibodies, rheumatoid factor and antinuclear antibody tests were positive. Given the patient's medical history, clinical manifestations, and laboratory, histopathological and immunofluorescence microscopy findings, a diagnosis of Rowell syndrome was made. Systemic corticosteroids (methylprednisolone; 0.5 mg/kg/day) and immunomodulatory therapy (azathioprine; 50 mg/day) were administered with the associated medication (omeprazole, 20 mg/day; KCl, 1 g/day) and topical dermocorticoids (fluticasone propionate 0.05% cream; 1 application/day), with a favorable outcome. The major diagnostic criteria for Rowell syndrome are the presence of lupus erythematosus (acute, subacute or systemic), erythema multiforme-like lesions and positive testing for antinuclear antibodies. The minor diagnostic criteria for Rowell syndrome are chilblains, the presence of anti-Ro antibodies and positive testing for rheumatoid factor. A diagnosis of Rowell syndrome is made if the patient exhibits all major criteria and at least one minor criterion. The present case m et al l diagnostic criteria, excluding the presence of chilblains. Notably, in this case there was a co-occurrence of subacute lupus erythematosus and Rowell

    Full Text Available Scrub typhus is an acute febrile illness caused by orientia tsutsugamushi, transmitted to humans by the bite of the larva of trombiculid mites. It causes a disseminated vasculitic and perivascular inflammatory lesions resulting in significant vascular leakage and end-organ injury. It affects people of all ages and even though scrub typhus in pregnancy is uncommon, it is associated with increased foetal loss, preterm delivery, and small for gestational age infants. After an incubation period of 6-21 days, onset is characterized by fever, headache, myalgia, cough, and gastrointestinal symptoms. A primary papular lesion which later crusts to form a flat black eschar, may be present. If untreated, serious complications may occur involving various organs. Laboratory studies usually reveal leukopenia, thrombocytopenia, deranged hepatic and renal function, proteinuria and reticulonodular infiltrate. Owing to the potential for severe complications, diagnosis, and decision to initiate treatment should be based on clinical suspicion and confirmed by serologic tests. A therapeutic trial of tetracycline or chloramphenicol is indicated in patients in whom the diagnosis of scrub typhus is suspected. The recommended treatment regimen for scrub typhus is doxycycline. Alternative regimens include tetracycline, chloramphenicol, azithromycin, ciprofloxacin, rifampicin, and roxithromycin. Treatment of pregnant women with azithromycin was successfully done without relapse and with favorable pregnancy outcomes. Hence, early diagnosis and treatment are essential in order to reduce the mortality and the complications associated with the disease. We searched the English-language literature for reports of scrub typhus in children, pregnant women, and non-pregnant patients with scrub typhus, using the MEDLINE/PubMed database, which includes citations from 1945 to the present time. We used the search terms ′scrub typhus′, ′scrub typhus′ and ′pregnancy′,

    Smooth muscle hamartoma is an uncommon cutaneous dysembryoplasia usually diagnosed in infancy. Among the 61 cases published since 1923, 56 were congenital and 3 appeared in young adults. We report a case in which the lesions started at the age of 15 years as a papular plaque in the right mammary region of a young woman. A review of the literature showed that the usual clinical presentation is a frequently pigmented plaque made of often follicular papules and measuring 1 to 10 centimeters on average. Excessive hairiness is the most frequent sign, being observed in more than two-thirds of the cases, and Darier's pseudo-sign is present in about 53 p. 100 of the patients. The disease is electively located on the lumbar region, the back and the root of the limbs. In 3 cases the lesions were generalized and the patients looked like fatty "Michelin-Tire Babies". The course of the disease is always favourable, and associated pathologies remain exceptional: urticaria pigmentosa and psychomotor retardation have been reported in two cases of the generalized form. Histology is characterized by the presence of numerous smooth muscle fibres disseminated in the dermis and diversely oriented, sometimes in contact with hair follicles which retain their normal morphology. The differential clinical diagnosis is with naevocytic naevus, café-au-lait spots, mastocytosis and connective tissue hamartoma. Belatedly revealed forms of the disease must be distinguished from Becker's hamartoma, but it must be known that in certain cases the classification is so difficult that some authors have suggested that smooth muscle hamartoma and Becker's hamartoma are only two poles of a single spectrum of dysembryoplastic lesions involving to varying degrees the epidermic and hair structures. Finally, the distinction between the localized forms of late onset smooth muscle hamartoma and multiple leiomyomas "en plaques" remains difficult both anatomico-clinically and nosologically.

    Backgrounds: Lichen planus is a chronic systemic disease and oral mucosa is commonly involved. Oral lichen planus (OLP) most commonly affects middle-aged women. The prevalence of the disease ranges between 0.5% and 2.6% in the general population and the range of malignant transformation varies between 0% and 10%. Objectives: To assess the rate of malignant transformation of OLP samples. Materials and Methods: This retrospective study was carried out on 112 medical records of patients with histological diagnosis of OLP who attended the Department of Pathology at the Educational Hospital from 2005 to 2012. H&E-stained slides were reviewed by two pathologists using strict clinical and histopathological diagnostic World Health Organization (WHO) criteria. Dysplastic changes were diagnosed and graded according to the latest WHO classification. Results: Of the 112 cases diagnosed as OLP, there were 39 males and 73 females and the patients’ ages ranged from 15 to 86 years (mean age 44.5 years). The erosive form with fifty cases was the most common clinical type and the papular type with one case was the least common clinical type. Regarding the site, the buccal mucosa was the most common site with 52 cases. Totally, dysplastic changes were found in 12 samples, among them five cases showed mild dysplasia and seven cases showed moderate dysplasia. One case developed oral squamous cell carcinoma after 3 years. Conclusion: OLP is considered as a premalignant condition by the WHO and several authors. Although the malignancy rate is not so high, to reduce morbidity and mortality from cancer arising on OLP lesions, a regular follow-up examination is recommended. PMID:27721603

    The term prurigo has been used for many decades in dermatology without clear definition, and currently used terminology of prurigo is inconsistent and confusing. Especially, itch-related prurigo remains unexplored regarding the epidemiology, clinical profile, natural course, underlying causes, available treatments and economic burden, although burdensome and difficult to treat. To address these issues, the multicentre European Prurigo Project (EPP) was designed to increase knowledge on chronic prurigo (CPG). In the first step, European experts of the EADV Task Force Pruritus (TFP) aimed to achieve a consensus on the definition, classification and terminology of CPG. Additionally, procedures of the cross-sectional EPP were discussed and agreed upon. Discussions and surveys between members of the TFP served as basis for a consensus conference. Using the Delphi method, consensus was defined as an agreement ≥75% among the present members. Twenty-four members of the TFP participated in the consensus conference. Experts consented that CPG should be used as an umbrella term for the range of clinical manifestations (e.g. papular, nodular, plaque or umbilicated types). CPG is considered a distinct disease defined by the presence of chronic pruritus for ≥6 weeks, history and/or signs of repeated scratching and multiple localized/generalized pruriginous skin lesions (whitish or pink papules, nodules and/or plaques). CPG occurs due to a neuronal sensitization to itch and the development of an itch-scratch cycle. This new definition and terminology of CPG should be implemented in dermatology to harmonize communication in the clinical routine, clinical trials and scientific literature. Acute/subacute forms of prurigo are separated entities, which need to be differentiated from CPG and will be discussed in a next step. In the near future, the cross-sectional EPP will provide relevant clinical data on various aspects of CPG leading to new directions in the scientific

    Full Text Available Abstract Definition of the disease Malignant atrophic papulosis (MAP, described independently by Köhlmeier and Degos et al., is a rare, chronic, thrombo-obliterative vasculopathy characterized by papular skin lesions with central porcelain-white atrophy and surrounding teleangiectatic rim. Epidemiology Less than 200 cases have been described in the literature. The first manifestation of MAP usually occurs between the 20th and 50th year of life. Clinical description The cutaneous clinical picture is almost pathognomonic. The histology is not consistent but in most cases it shows a wedge-shaped connective tissue necrosis in the deep corium due to a thrombotic occlusion of the small arteries. In the systemic variant, manifestations mostly occur at the intestine and central nervous system. Etiology The etiopathogenesis of the disease remains unknown, a genetic predisposition may occur. Vasculitis, coagulopathy or primary dysfunction of the endothelial cells have been implicated. Diagnostic methods Diagnosis is only based on the characteristic skin lesions. Differrential diagnosis It depends on the clinical presentation of MAP, but systemic lupus erythematosus and other connective tissue diseases need to be considered. Management No effective treatment exists for the systemic manifestations, while compounds that facilitate blood perfusion have achieved a partial regression of the skin lesions in single cases. Prognosis An apparently idiopathic, monosymptomatic, cutaneous, benign variant and a progressive, visceral one with approx. 50% lethality within 2–3 years have been reported. Systemic manifestations can develop years after the occurrence of skin lesions leading to bowel perforation and peritonitis, thrombosis of the cerebral arteries or massive intracerebral hemorrhage, meningitis, encephalitis, radiculopathy, myelitis.

    Parapoxviruses (PPV), of the family Poxviridae, cause a pustular cutaneous disease in sheep and goats (orf virus, ORFV) and cattle (pseudocowpoxvirus, PCPV and bovine papular stomatitis virus, BPSV). Here, we present the first genomic sequence of a reference strain of PCPV (VR634) along with the genomic sequence of a PPV (F00.120R) isolated in Finland from reindeer (Rangifer tarandus tarandus). The F00.120R and VR634 genomes are 135 and 145 kb in length and contain 131 and 134 putative genes, respectively, with their genome organization being similar to that of other PPVs. The predicted proteins of F00.120R and VR634 have an average amino acid sequence identity of over 95%, whereas they share only 88 and 73% amino acid identity with the ORFV and BPSV proteomes, respectively. The most notable differences were found near the genome termini. F00.120R lacks six and VR634 lacks three genes seen near the right terminus of other PPVs. Four genes at the left end of F00.120R and one in the middle of both genomes appear to be fragmented paralogues of other genes within the genome. VR634 has larger than expected inverted terminal repeats possibly as a result of genomic rearrangements. The high G+C content (64%) of these two viruses along with amino acid sequence comparisons and whole genome phylogenetic analyses confirm the classification of PCPV as a separate species within the genus Parapoxvirus and verify that the virus responsible for an outbreak of contagious stomatitis in reindeer over the winter of 1999-2000 can be classified as PCPV.

    Terra firma-forme (i.e. resembling dry earth) is a condition chiefly affecting children wrongly considered as dermatosis arising out of negligence and inadequate corporal hygiene. It is in fact an acquired and asymptomatic grey-brown hyperpigmentation of the skin that persists despite normal washing with soap and water, but which subsides on rubbing with isopropyl alcohol 70%. Herein we report 10 new cases of this disorder. Ten patients aged between 7 months in 17 years were seen for acquired macular skin pigmentation, either brown or grey, fragmented and confluent. In six patients, this abnormality was the main reason for the consultation, generally on aesthetic grounds, and more rarely for diagnosis or suspicion of acanthosis nigricans. In all cases, questioning revealed normal hygiene measures. The condition comprised macular or acquired papular pigmentation, either brown or grey, of bilateral and symmetrical disposition and electively affecting the neck, trunk and retro-malleolar area of the ankles. Clinical examination together with a test involving rubbing with isopropyl alcohol 70° confirmed the diagnosis, revealing healthy underlying skin. Terra firma-forme dermatosis is frequently seen in clinical practice but is largely ignored in the French literature, possibly because of relevant indifference towards the condition. It affects both sexes equally, with no predilection for age or ethnicity, although it is classically seen to a greater extent during adolescence. Diagnosis of the condition, which is easily made thanks to the hyperpigmentation of dirty brown appearance on the neck and the ankles in particular, should not mislead the practitioner into blaming patients for supposedly deficient body hygiene. Knowledge of this form of dermatosis is useful because of its potentially harmful aesthetic and social effects, despite the ease of treatment by insistent rubbing of the affected areas with medical alcohol or ether. Early recognition also avoids pointless

    Full Text Available The purpose of this study was to compare macroscopic dermatopathology in naïve and sensitised goats, and to assess protective immunity possessed by sensitised goats against Sarcoptes scabiei challenge. Eighteen goats were allocated evenly into 3 groups; group 1 sensitised with the mite twice, group 2 once and group 3 was not sensitised (naïve. Sensitisation was done by infesting goats with the mites on the auricle and infestation was allowed to progress for 7 weeks, then the goats were treated with Ivermectin to obtain complete recovery. After sensitisation, all sensitised and naïve goats were infested with the mites on the auricles. Infestation in the sensitised goat caused severe immediate hypersensitivity that resulted in severe peracute pustular dermatitis. After one week, however, the lesion waned slowly. At 7 weeks post infestation, the remnant of lesion could only be perceived by palpation on the primary site of infestation as a mild papular dermatitis. Infestation on the naïve goats, in contrast, produced slowly progressing lesions which at 7-week post infestation, it ended up with severe crusted scabies affecting almost the whole skin. Antigens responsible for the immediate hypersensitivity which are supposedly contained in the mite secretions or excretions are immunologically protective but unlikely to have the capacity to induce a complete protection against mite challenge in immunised animals. This notion is based on the fact obtained from this study that goats sensitised twice did not possess a higher immune protection against mite challenge than goats sensitised once.

Previous studies have shown the clinical efficacy of Avène thermal spring water in AD, and a new microorganism, Aquaphilus dolomiae was suspected to contribute to these unique properties. The present study evaluated the anti-inflammatory, antipruritic, and immunomodulatory properties of ES0, an original biological extract of A. dolomiae, in immune and inflammatory cell models in order to assess its potential use in the treatment of AD.Materials and methods: An ES0 extract containing periplasmic and membrane proteins, peptides, lipopolysaccharides, and exopolysaccharides was obtained from A. dolomiae. The effects of the extract on pruritus and inflammatory mediators and immune mechanisms were evaluated by using various AD cell models and assays.Results: In a keratinocyte model, ES0 inhibited the expression of the inflammatory mediators, thymic stromal lymphopoietin, interleukin (IL-18, IL-4R, IL-8, monocyte chemoattractant protein-3, macrophage inflammatory protein-3α, and macrophage-derived chemokine and induced the expression of involucrin, which is involved in skin barrier keratinocyte terminal differentiation. In addition, ES0 inhibited protease-activated receptor-2 activation in

    Atopic dermatitis is a chronic and severe pruritic skin disease. Interlukin-31 (IL-31) has been recently demonstrated to be one of the key pruritogens in atopic dermatitis. However, the mechanisms underlying IL-31-induced itching remains unclear. In our previous study, we have shown that thromboxane (TX) A 2 is involved in itch-associated responses in mice with atopy-like skin diseases. IL-31 was given intradermally into the rostral back of ICR mice and the hind-paw scratching to the injection site were counted. Expression of TX synthase and IL-31 receptors were analyzed using immunohistochemical staining or RT-PCR in mouse skin or primary cultures of mouse keratinocytes. The concentration of TXB 2 , a metabolite of TXA 2 , in the skin and the culture medium of primary cultures of mouse keratinocytes was measured using enzyme immunoassay. The concentration of intracellular Ca 2+ ions in mouse keratinocytes was measured using the calcium imaging method. An intradermal injection of IL-31 elicited scratching, an itch-related response, in mice. The scratching was inhibited by TP TXA 2 receptor antagonist DCHCH. The distribution of TX synthase and IL-31RA receptor was mainly epidermal keratinocytes in the skin. The primary cultures of keratinocytes expressed the mRNAs of TX synthase and IL-31 receptors. IL-31 increased the concentration of TXB 2 , which was inhibited by TX synthase inhibitor sodium ozagrel and EGTA, in the skin and the culture medium of primary cultures of keratinocytes. IL-31 increased the concentration of intracellular Ca 2+ ions in mouse keratinocytes. It is suggested that IL-31 elicits itch-associated responses through TXA 2 produced from keratinocytes.

    To determine epidemiological, clinical and mycological characteristics of vulvovaginal candidiasis (VVC) in Tunisian population and to evaluate predisposing factors. In this retrospective study, 2160 vaginal swabs were performed over 2 years (January 2014-December 2015). It was carried out at the laboratory of Parasitology and Mycology, Rabta Hospital in Tunisia. After swab collecting, direct examination and culture on Sabouraud Chloramphenicol and Sabouraud Chloramphenicol Actidione media were implemented to research yeasts. Then identifying of yeast species was through chlamydosporulation test and auxanogram. For each patient, a questionnaire was filled noting age, medical and surgical history, symptoms and risk factors. Statistical analysis of data was performed on SPSS 16 using Khi 2 test, P<0.05 was considered significant. Direct examination was positive showed spore and/or pseudohypha in 24.72%. Candida albicans was isolated most frequently (76.61%) followed by Candida glabrata (17.18%). The maximum frequency of Candida-positive cultures was in 25-34 years old age group. Leucorrhea was the most common symptom (72.25%) followed by vulvar prurits (63.23%), dyspareunia (32.25%) and urinary burning (24.92%). Only pregnancy was correlated positively with VVC. It appears from our study that VVC is relatively common in Tunisia. His diagnosis results from confrontation of anamnestic, clinical and mycological data. The knowledge of risk factors and their correction would be necessary to prevent the occurrence of VVC, especially in its recurrent form. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Immune reconstitution inflammatory syndrome (IRIS) is a condition associated with paradoxical worsening and/or new onset of an opportunistic infection in HIV patients following the initiation of anti-retroviral therapy or switching to more potent antiretroviral therapy (ART) regimen. Although IRIS associated with many opportunistic infections (OIs) has been well reported, syphilis has very rarely been mentioned in this regard. A 52-year-old male, diagnosed with AIDS six weeks ago, presented with the disseminated non-pruritic painless skin rash. He denied any fever, cough, shortness of breath, and joint pain or swelling. The patient had no similar symptoms, genital ulcers, or any medical illness in the past. CD4 cell count and viral load were 40 cells/mm 3 and 280,000 copies/ml, respectively, while screening tests for OIs including rapid plasma reagin test, quantiferon, cryptococcal antigen, and toxoplasma tests were negative at the time of HIV diagnosis. After three days of initiation of anti-retroviral therapy, he developed the above-mentioned skin rash. Repeat rapid plasma regain (RPR) test at this time was also negative. Punch biopsy of the skin lesion demonstrated findings suggestive of secondary syphilitic lesions, which was confirmed by immunostain. The repeat RPR, CD4 cell count, and viral load showed a titer of 1:256, 257 cells/mm 3 , and 5000 copies/ml, respectively. His skin rashes faded away, and RPR titer trended down on treatment with benzathine penicillin without discontinuation of ART. The presence of an IRIS response does not predict overall HIV or OI treatment responses, and discontinuation of ART is not generally recommended as the benefits of treating HIV infection outweighs the risk associated with IRIS.

    Scabies is an ancient disease (documented as far back as 2500 years ago). It affects about 300 million people annually worldwide, and the prevalence is as high as about 60% in Indigenous and Torres Strait Islander children in Australia. This is more than six times the rate seen in the rest of the developed world. Scabies is frequently complicated by bacterial infection leading to the development of skin sores and other more serious consequences such as septicaemia and chronic heart and kidney diseases. This causes a substantial social and economic burden especially in resource poor communities around the world. Very few treatment options are currently available for the management of scabies infection. In this manuscript we briefly discuss the clinical consequences of scabies and the problems found (studies conducted in Australia) with the currently used topical and oral treatments. Current scabies treatment options are fairly ineffective in preventing treatment relapse, inflammatory skin reactions and associated bacterial skin infections. None have ovicidal, antibacterial, anti-inflammatory and/or anti-pruritic properties. Treatments which are currently available for scabies can be problematic with adverse effects and perhaps of greater concern the risk of treatment failure. The development of new chemical entities is doubtful in the near future. Though there may be potential for immunological control, the development of a vaccine or other immunotherapy modalities may be decades away. The emergence of resistance among scabies mites to classical scabicides and ineffectiveness of current treatments (in reducing inflammatory skin reactions and secondary bacterial infections associated with scabies), raise serious concerns regarding current therapy. Treatment adherence difficulties, and safety and efficacy uncertainties in the young and elderly, all signal the need to identify new treatments for scabies.

    Scabies, a highly pruritic and contagious mite infestation of the skin, is endemic among tropical regions and causes a substantial proportion of skin disease among lower-income countries. Delayed treatment can lead to bacterial superinfection, and treatment of close contacts is necessary to prevent reinfestation. We describe scabies incidence and superinfection among children in American Samoa (AS) to support scabies control recommendations. We reviewed 2011-2012 pharmacy records from the only AS pharmacy to identify children aged ≤14 years with filled prescriptions for permethrin, the only scabicide available in AS. Medical records of identified children were reviewed for physician-diagnosed scabies during January 1, 2011-December 31, 2012. We calculated scabies incidence, bacterial superinfection prevalence, and reinfestation prevalence during 14-365 days after first diagnosis. We used log binomial regression to calculate incidence ratios for scabies by age, sex, and county. Medical record review identified 1,139 children with scabies (incidence 29.3/1,000 children aged ≤14 years); 604 (53%) had a bacterial superinfection. Of 613 children who received a scabies diagnosis during 2011, 94 (15.3%) had one or more reinfestation. Scabies incidence varied significantly among the nine counties (range 14.8-48.9/1,000 children). Children aged scabies diagnosis than children aged 10-14 years. Scabies and its sequelae cause substantial morbidity among AS children. Bacterial superinfection prevalence and frequent reinfestations highlight the importance of diagnosing scabies and early treatment of patients and close contacts. Investigating why certain AS counties have a lower scabies incidence might help guide recommendations for improving scabies control among counties with a higher incidence. We recommend interventions targeting infants and young children who have frequent close family contact.

Methodology/Principal Findings We reviewed 2011–2012 pharmacy records from the only AS pharmacy to identify children aged ≤14 years with filled prescriptions for permethrin, the only scabicide available in AS. Medical records of identified children were reviewed for physician-diagnosed scabies during January 1, 2011–December 31, 2012. We calculated scabies incidence, bacterial superinfection prevalence, and reinfestation prevalence during 14–365 days after first diagnosis. We used log binomial regression to calculate incidence ratios for scabies by age, sex, and county. Medical record review identified 1,139 children with scabies (incidence 29.3/1,000 children aged ≤14 years); 604 (53%) had a bacterial superinfection. Of 613 children who received a scabies diagnosis during 2011, 94 (15.3%) had one or more reinfestation. Scabies incidence varied significantly among the nine counties (range 14.8–48.9/1,000 children). Children aged scabies diagnosis than children aged 10–14 years. Conclusions/Significance Scabies and its sequelae cause substantial morbidity among AS children. Bacterial superinfection prevalence and frequent reinfestations highlight the importance of diagnosing scabies and early treatment of patients and close contacts. Investigating why certain AS counties have a lower scabies incidence might help guide recommendations for improving scabies control among counties with a higher incidence. We recommend interventions targeting infants and young children who have frequent close family contact

    The discovery of the histamine H 4 receptor (H 4 R) provided a new avenue for the exploration of the physiological role of histamine, as well as providing a new drug target for the development of novel antihistamines. The first step in this process was the identification of selective antagonists to help unravel the pharmacology of the H 4 R relative to other histamine receptors. The discovery of the selective H 4 R antagonist JNJ 7777120 was vital for showing a role for the H 4 R in inflammation and pruritus. While this compound has been very successful as a tool for understanding the function of the receptor, it has drawbacks, including a short in vivo half-life and hypoadrenocorticism toxicity in rats and dogs, that prevented advancing it into clinical studies. Further research let to the discovery of JNJ 39758979, which, similar to JNJ 7777120, was a potent and selective H 4 R antagonist and showed anti-inflammatory and anti-pruritic activity preclinically. JNJ 39758979 advanced into human clinical studies and showed efficacy in reducing experimental pruritus and in patients with atopic dermatitis. However, development of this compound was terminated due to the occurrence of drug-induced agranulocytosis. This was overcome by developing another H 4 R antagonist with a different chemical structure, toreforant, that does not appear to have this side effect. Toreforant has been tested in clinical studies in patients with rheumatoid arthritis, asthma, or psoriasis. In conclusions there have been many H 4 R antagonists reported in the literature, but only a few have been studied in humans underscoring the difficulty in finding ligands with all of the properties necessary for testing in the clinic. Nevertheless, the clinical data to date suggests that H 4 R antagonists can be beneficial in treating atopic dermatitis and pruritus.

    Full Text Available Pruritus is an unpleasant sensation that provokes the desire to scratch. It has long been recognized as a presenting or concomitant symptom of many systemic diseases. Indeed, generalized pruritus is reported to be associated with underlying diseases in 10-50 percent of cases. This study was conducted to investigate the underlying diseases in pruritic patients without primary skin lesion. Seventy-five patients with at least one-month history of pruritus with no primary skin lesions, presenting to dermatological clinics of Razi Hospital, from April 97 until December 99 were evaluated. The work up procedure consisted of medical history, physical examination, laboratory findings (CBC, ESR, blood chemistry, thyroid function tests, urinalysis, stool exam, chest X-ray and in selected cases, additional specific tests. Fifty-four patients were female, and 21 male the mean age was 45.7y±16.41, and the mean duration of pruritus, 21.8m±21. In 43 patients (75.4 percent, no abnormal finding was detected. Five patients (6.66 percent had atopy. In the remaining 27 patients (36 percent, the following abnormalities were found: Iron deficiency in 6 patients (8 percent, diabetes mellitus in 6 patients (8 percent, hyperthyroidism in 4 patients (5.33 percent, hypothyroidism in 2 patients (2.66 percent, lymphoma in 3 patients (4 percent, chronic hepatitis, hypocalcaemia, cholelithiasis, psychosis and chronic renal failure each in one patient (1.3 percent. Evaluation of patients with pruritus may be a valuable tool for early detection of underlying systemic diseases.

    Tattoos cause a broad range of clinical problems. Mild complaints, especially sensitivity to sun, are very common and seen in 1/5 of cases. Medical complications are dominated by allergy to tattoo pigment haptens or haptens generated in the skin, especially in red tattoos but also in blue and green tattoos. Symptoms are major and can be compared to cumbersome pruritic skin diseases. Tattoo allergies and local reactions show distinct clinical manifestations, with plaque-like, excessive hyperkeratotic, ulcero-necrotic, lymphopathic, neuro-sensory, and scar patterns. Reactions in black tattoos are papulo-nodular and non-allergic and associated with the agglomeration of nanoparticulate carbon black. Tattoo complications include effects on general health conditions and complications in the psycho-social sphere. Tattoo infections with bacteria, especially staphylococci, which may be resistant to multiple antibiotics, may be prominent and may progress into life-threatening sepsis. Contaminated tattoo ink is an open-window risk vector that can lead to epidemic tattoo infections across national borders due to contaminated bulk production. Hepatitis B and C and human immunodeficiency virus (HIV) transferred by tattooing remain a significant risk needing active prevention. It is noteworthy that cancer arising in tattoos, in regional lymph nodes, and in other organs due to tattoo pigments and ingredients has not been detected or noted as a significant clinical problem hitherto, despite millions of people being tattooed for decennia. Clinical observation and epidemiology disagree with register data, which indicate an increased risk of cancer due to chemical carcinogens present in some inks. Registers rely on chronic dosaging of cell lines and animals. However, tattooing in humans is essentially a single-dose exposure, which might explain the observed discrepancy. © 2015 S.

    Balneology can be part of the plastic surgery care sector. The objectives of this study were firstly to the state of knowledge about the hydrotherapy and specify the place reserved for hydrotherapy by surgeons as an adjunct in plastic and reconstructive surgery (adult and child). Multicentric national study by poll (Google Drive®) focused at plastic and/or pediatric surgeons. The following information was analyzed: frequency, timing of prescription, indications, the surgeon's feelings towards hydrotherapy and the differences between adult's and children's prescriptions. Fifty-four teams were contacted: 22 responses were received (15 "adult" plastic surgeons, 9 "pediatric" plastic surgeons, 6 pediatric surgeons, with 12 out of 22 working with burnt patients). Eighteen out of 22 prescribed hydrotherapy. Twenty out of 22 thought that hydrotherapy had a role as adjuvant therapy in plastic surgery. The indications were: burns (11/20), skin-graft hypertrophy (10/20), inflammatory and pruritic scar and cutaneous trophic disorders (9/20), psychological (3/20), retractions (2/20), weight loss and smoking (1/20). The timing of the prescription was: 6 months and 1 year (8/20) after surgery/trauma. Twenty out of 22 found a beneficial effect: physical (19/20): reduction of inflammatory signs, pruritus and pain, scar maturation, skin thinning improvement; psychological (14/20): positive for patient/family. Five out of 17 made the difference between child/adult, 10/17 made no difference but only treated adults or children. The respondents in the study are probably more sensitive to the effects of hydrotherapy that non-respondents. It is difficult to assess the real impact of hydrotherapy in plastic surgery because distinguishing spontaneous favorable evolution of a scar from one only due to the hydrotherapy or multidisciplinary management is difficult. However, hydrotherapy seems to have its role among multidisciplinary management. Copyright © 2015 Elsevier Masson SAS. All

    Background Scabies is a parasitic skin infestation caused by the burrowing mite Sarcoptes scabiei. It is common worldwide and spreads rapidly under crowded conditions, such as those found in socially disadvantaged communities of Indigenous populations and in developing countries. Pruritic scabies lesions facilitate opportunistic bacterial infections, particularly Group A streptococci. Streptococcal infections cause significant sequelae and the increased community streptococcal burden has led to extreme levels of acute rheumatic fever and rheumatic heart disease in Australia's Indigenous communities. In addition, emerging resistance to currently available therapeutics emphasizes the need to identify potential targets for novel chemotherapeutic and/or immunological intervention. Scabies research has been severely limited by the availability of parasites, and scabies remains a truly neglected infectious disease. We report development of a tractable model for scabies in the pig, Sus domestica. Methodology/Principal Findings Over five years and involving ten independent cohorts, we have developed a protocol for continuous passage of Sarcoptes scabiei var. suis. To increase intensity and duration of infestation without generating animal welfare issues we have optimised an immunosuppression regimen utilising daily oral treatment with 0.2mg/kg dexamethasone. Only mild, controlled side effects are observed, and mange infection can be maintained indefinitely providing large mite numbers (>6000 mites/g skin) for molecular-based research on scabies. In pilot experiments we explore whether any adaptation of the mite population is reflected in genetic changes. Phylogenetic analysis was performed comparing sets of genetic data obtained from pig mites collected from naturally infected pigs with data from pig mites collected from the most recent cohort. Conclusions/Significance A reliable pig/scabies animal model will facilitate in vivo studies on host immune responses to scabies

    Membrane plasma exchange (PE) is a mode of extracorporeal blood purification. Since 1985 membrane PE has been in regular use at the Department of Nephrology, Medical Faculty of Skopje, R.Macedonia. In this paper we report on five years (2000-2004) of single centre plasma exchange activity. We performed 540 PE treatments (108 PE/per year) on 99 patients. The M/F ratio was 40/48. The patients underwent a median of 5.45 procedures (range, 1-16). The treated patients were from different Departments. Protocols for PE depend on the disease and its severity. PE were performed 2-4 times weekly using Gambro PF 2000 N filters with an adaptation of the Gambro AK10 dialysis machine or with the Gambro Prizma machine (2 cases). Blood access was achieved through femoral vein. Substitution was made with fresh frozen plasma and/or with 20% human albumin combined with Ringer's solution. An average amount of 2150 ml plasmafiltrate per treatment (respectively 30 to 40 ml plasmafiltrate/kg body weight) was eliminated. Most therapeutic procedures were performed on patients from the Department of Neurology. 63.6% of all patients were referred for Myasthenia gravis and the Guillian Barre syndrome. The total number of procedures per year has remained fairly stable, corresponding to a median of 5.4 treatments/100 000 inhabitants. We observed hypocalcaemia in 8% of the patients, urticarial reactions in 7.3%, pruritic reactions in 12%, and hypotension/headache in 6.8%. No major procedural complications were seen.

    Tinea pedis is the most common dermatophyte infection. Treatment is critical to alleviate pruritic symptoms, to reduce the risk for secondary bacterial infection, and to limit the spread of infection to other body sites or other individuals. The objective of this study was to compare the abilities of econazole nitrate topical foam, 1% and ketoconazole cream (2%) to reduce pruritus, thus improving quality of life, and to determine patient preference for the foam product versus the cream product in patients with interdigital tinea pedis. A single-center, investigator-blinded, observational pilot study was conducted to compare econazole nitrate topical foam (1%) to ketoconazole cream (2%). In this split-body study, 20 subjects received both econazole nitrate topical foam and ketoconazole cream and applied the medications daily to either the right or left foot for 14 days. Improvements in patient quality of life (pruritus) and patient preference were measured using the pruritus visual analog scale (VAS), Skindex-16, and patient preference questionnaires. Nineteen subjects completed the study and one subject was lost to follow-up. Reductions in VAS scores of econazole nitrate topical foam were significantly greater than those of ketoconazole cream, indicating the superiority of the econazole nitrate foam in reducing pruritus. Skindex-16 data showed significant reductions in total scores and individual domains, including patient symptom, emotional, and functional domains, by the final visit. Since each subject received both medications the questionnaire was not medication-specific. Responses to patient preference questionnaires showed that econazole nitrate topical foam,1% was rated as "good" or "excellent" in all measures assessed. One adverse event was noted. In patients with interdigital tinea pedis, application of econazole nitrate topical foam 1% twice daily for two weeks was clinically effective and significantly superior to ketoconazole cream 2% in reducing

    Traditional remedies are an integral part of Colombian culture. Here we present the results of a three-year study of ethnopharmacology and folk-medicine use among the population of the Atlantic Coast of Colombia, specifically in department of Bolívar. We collected information related to different herbal medicinal uses of the local flora in the treatment of the most common human diseases and health disorders in the area, and determined the relative importance of the species surveyed. Data on the use of medicinal plants were collected using structured interviews and through observations and conversations with local communities. A total of 1225 participants were interviewed. Approximately 30 uses were reported for plants in traditional medicine. The plant species with the highest fidelity level (Fl) were Crescentia cujete L. (flu), Eucalyptus globulus Labill. (flu and cough), Euphorbia tithymaloides L. (inflammation), Gliricidia_sepium_(Jacq.) Kunth (pruritic ailments), Heliotropium indicum L. (intestinal parasites) Malachra alceifolia Jacq. (inflammation), Matricaria chamomilla L. (colic) Mentha sativa L. (nervousness), Momordica charantia L. (intestinal parasites), Origanum vulgare L. (earache), Plantago major L. (inflammation) and Terminalia catappa L. (inflammation). The most frequent ailments reported were skin affections, inflammation of the respiratory tract, and gastro-intestinal disorders. The majority of the remedies were prepared from freshly collected plant material from the wild and from a single species only. The preparation of remedies included boiling infusions, extraction of fresh or dry whole plants, leaves, flowers, roots, fruits, and seeds. The parts of the plants most frequently used were the leaves. In this study were identified 39 plant species, which belong to 26 families. There was a high degree of consensus from informants on the medical indications of the different species. This study presents new research efforts and perspectives on the

    Hypocomplementemic urticarial vasculitis (HUV) is an uncommon vasculitis of unknown etiology that is rarely described in the literature. We undertook this study to analyze the clinical spectrum and the therapeutic management of patients with HUV. We conducted a French nationwide retrospective study that included 57 patients with chronic urticaria, histologic leukocytoclastic vasculitis, and hypocomplementemia. We assessed clinical and laboratory data and evaluated the patients' cutaneous and immunologic responses to therapy. We evaluated treatment efficacy by measuring the time to treatment failure. Urticarial lesions were typically more pruritic than painful and were associated with angioedema in 51% of patients, purpura in 35%, and livedo reticularis in 14%. Extracutaneous manifestations included constitutional symptoms (in 56% of patients) as well as musculoskeletal involvement (in 82%), ocular involvement (in 56%), pulmonary involvement (in 19%), gastrointestinal involvement (in 18%), and kidney involvement (in 14%). Patients with HUV typically presented with low C1q levels and normal C1 inhibitor levels, in association with anti-C1q antibodies in 55% of patients. Hydroxychloroquine or colchicine seemed to be as effective as corticosteroids as first-line therapy. In patients with relapsing and/or refractory disease, rates of cutaneous and immunologic response to therapy seemed to be higher with conventional immunosuppressive agents, in particular, azathioprine, mycophenolate mofetil, or cyclophosphamide, while a rituximab-based regimen tended to have higher efficacy. Finally, a cutaneous response to therapy was strongly associated with an immunologic response to therapy. HUV represents an uncommon systemic and relapsing vasculitis with various manifestations, mainly, musculoskeletal and ocular involvement associated with anti-C1q antibodies, which were found in approximately half of the patients. The best strategy for treating HUV has yet to be defined

    Full Text Available Introduction:Cutaneous drug reactions may be classified with regard to pathogenesis and clinical morphology. They may be mediated by both immunologic and non-immunologic mechanisms.Case report:A 56 year old female presented with widespread patches and macules, concentrated on her face, trunk and extremities. The lesions were pruritic, and temporally associated with intake of benzapril hydrochloride, imidapril and metformin.Methods:Biopsies for hematoxylin and eosin (H&E examination, as well as for immunohistochemistry (IHC and direct immunofluorescence (DIF analysis were performed for diagnostic purposes, and also to evaluate the lesional immune response.Results:Hematoxylin and eosin staining demonstrated a histologically unremarkable epidermis. Within the dermis, a moderately florid, superficial and deep, perivascular infiltrate of lymphocytes, plasmacytoid lymphocytes, histiocytes and rare eosinophils was identified, consistent with an allergic drug reaction. DIF demonstrated deposits of IgE, Complement/C3 and fibrinogen around dermal blood vessels. IHC demonstrated positive staining with HAM-56 and myeloid/histoid antigen in the cell infiltrate around the upper dermal blood vessels. HLA-ABC was overexpressed around those vessels, as well as around dermal sweat glands. COX-2 demonstrated positive staining in both the epidermis and upper dermis.Conclusion:Drug reactions are significant causes of skin rashes. In the current case, we were able to identify multiple antigen presenting cells in the area of the main inflammatory process. The immunologic case findings suggest that allergic drug eruptions may represent complex processes. An allergic drug reaction should be suspected whenever dermal, perivascular deposits of fibrinogen, Complement/C3 and other markers such as IgE are identified via DIF.

    Atopic dermatitis (AD) is a chronic and relapsing skin disorder characterized by pruritic and dry skin lesions with allergic inflammation. Recent studies have revealed anti-inflammatory and anti-allergic effects of xanthones in mangosteen through regulation of the nuclear factor (NF)-κB signaling pathway. Activation of NF-κB signals is responsible for allergic inflammation in AD. To develop a new preventive therapy for AD, we examined the effects of the natural medicine, mangosteen rind extract (ME), on AD in a murine model. ME (250 mg/kg per day) was administrated to NC/Tnd mice, a model for human AD, for 6 weeks to evaluate its preventive effects on AD. We also confirmed the effects of ME on various immune cell functions. Oral administration of ME prevented the increase of clinical skin severity scores, plasma total immunoglobulin E levels, scratching behavior, transepidermal water loss and epidermal hyperplasia in NC/Tnd mice; moreover, no adverse effects were noted. We demonstrated that ME suppressed thymic stromal lymphopoietin and interferon-γ mRNA expression both in vitro and in vivo. Not only immunoglobulin E production from splenic B cells but also immunoglobulin E-mediated degranulation of bone marrow-derived cultured mast cells was significantly reduced by the addition of ME to the culture. In addition, mRNA expression levels of nerve growth factor were decreased in ME-administrated NC/Tnd mice compared with those of controls. Keratinocyte proliferation was well-controlled by ME application. Oral administration of ME exhibited its suppressive potential on the early development of AD by controlling inflammation, itch and epidermal barrier function. © 2013 Japanese Dermatological Association.

    Atopic dermatitis (AD) is characterized by highly pruritic, chronic, relapsing inflammatory skin lesions. Furthermore, therapeutic choices are limited, especially in long-standing cases, despite its increasing prevalence. This study was performed to examine the clinical efficacy and the therapeutic mechanism underlying the effects of Actinidia arguta (hardy kiwi) fruit extract in an animal model of AD. To examine the effects of A. arguta extract on AD, 2-chloro-1,3,5-trinitrobenzene-treated NC/Nga mice were orally administered A. arguta extract (100 mg/kg/day), tacrolimus (1 mg/kg/day), or dexamethasone (3 mg/kg/day) for 8 weeks. Skin severity scores, epidermal thickening, mast cell infiltration and degranulation, total serum immunoglobulin (Ig) isotypes (IgE, IgG(1)), and cytokine (interleukin [IL]-4 and interferon [IFN]-gamma) and Toll-like receptor (TLR) (TLR-2, TLR-4, and TLR-9) expressions were examined in each of the study groups. Orally administered A. arguta extract significantly reduced clinical dermatitis severity, epidermal thickness, mast cell dermal infiltration and degranulation, and total levels of serum IgE and IgG(1). Furthermore, this suppression of total serum IgE and IgG(1) levels was accompanied by a decrease in IL-4 and an increase in IFN-gamma expression in skin and splenocytes. Interestingly, TLR-9 expression was increased by oral A. arguta extract. This study confirms that A. arguta extract has potential as a dietary therapeutic agent for the treatment of AD. Furthermore, our findings suggest that its clinical efficacy and mode of action against AD are associated with the modulation of biphasic T-helper (Th) 1/Th2 cytokines, with the inhibition of Th2-mediated IgE overproduction, and possibly with the up-regulation of TLR-9.

    A previously validated 15-item questionnaire on dogs' life quality (QoL1) and that of their owners (QoL2) was applied in a multicentre study to owners of 200 dogs with different dermatological conditions, together with a question on the owner-perceived disease severity (S). Factor analysis was applied to the whole questionnaire. The correlation of S with QoL1 and QoL2 scores was evaluated using Spearman's rank correlation tests. Owner sex, age, educational level and willingness to pay for a potential definitive cure of the disease were recorded, and compared with quality of life (QoL) scores. In 23 atopic dogs, CADESI-03, pruritus Visual Analogue Scale and QoL scores were obtained before and after therapy, and their correlation was evaluated with linear regression. Factor analysis revealed that three factors (S, QoL1 and QoL2) explained 75% of the variance. Owner-perceived severity correlated significantly with QoL1 and QoL2 (P = 0.002 and P = 0.015, respectively). The five diseases with the worst QoL scores were scabies, pododermatitis, complicated atopic dermatitis, pemphigus foliaceus and endocrine alopecia. Pruritic diseases did not give significantly higher QoL1 or QoL2 scores compared with nonpruritic diseases (P = 0.19, Kruskall-Wallis test). Owner sex, age or educational level did not influence QoL scores. Female sex, a younger age and a higher educational level were significantly associated with more willingness to pay. In atopic dogs, all the scores decreased after therapy, but post-treatment CADESI-03 and Visual Analogue Scale scores did not correlate with QoL1 and QoL2. Questions related to the burden of maintenance therapy showed the lowest improvements in score. © 2011 The Authors. Veterinary Dermatology. © 2011 ESVD and ACVD.

    Full Text Available Transient receptor potential vanilloid type 1 (TRPV1 is a non-selective cation channel widely expressed in skin tissues, and peripheral sensory nerve fibres. Activation of TRPV1 releases neuropeptides; the resulting neurogenic inflammation is believed to contribute to the development of pruritus. A TRPV1 antagonist has the potential to perform as an anti-pruritic agent. SB705498 is a TRPV1 antagonist that has demonstrated in vitro activity against cloned TRPV1 human receptors and when orally administered has demonstrated pharmacodynamic activity in animal models and clinical studies.To select a topical dose of SB705498 using the TRPV1 agonist capsaicin; to confirm engagement of the TRPV1 antagonistic action of SB705498 and assess whether the dose selected has an effect on itch induced by two challenge agents.A clinical study was conducted in 16 healthy volunteers to assess the effects of 3 doses of SB705498 on skin flare induced by capsaicin. Subjects with a robust capsaicin response were chosen to determine if the selected topical formulation of SB705498 had an effect on challenge agent induced itch.Following capsaicin challenge the greatest average reduction in area of flare was seen for the 3% formulation. This dose was selected for further investigation. Itch intensity induced by two challenge agents (cowhage and histamine was assessed on the Computerised Visual Analogue Scale. The difference in average itch intensity (Weighted Mean Over 15 Mins between the 3% dose of SB705498 and placebo for the cowhage challenge was -0.64, whilst the histamine challenge showed on average a -4.65 point change.The 3% topical formulation of SB705498 cream was clinically well tolerated and had target specific pharmacodynamic activity. However there were no clinically significant differences on pruritus induced by either challenge agent in comparison to placebo.

    Full Text Available Abstract Background Pelodera (Rhabditis strongyloides is a small saprophytic nematode that lives in decaying organic matter. On rare occasions, it can invade the mammalian skin, causing a pruritic, erythematous, alopecic and crusting dermatitis on skin sites that come into contact with the ground. Diagnosis of the disease is based on case history (a dog living outdoors on damp straw bedding with characteristic skin lesions and on the demonstration of typical larvae in skin scrapings or biopsy. Pelodera (rhabditic dermatitis cases have been reported mainly from Central European countries and the United States. Case presentation During 1975–1999, we verified 11 canine cases of Pelodera dermatitis in Finland. The cases were confirmed by identifying Pelodera larvae in scrapings. Biopsies for histopathology were obtained from three cases, and typical histopathological lesions (epidermal hyperplasia, epidermal and follicular hyperkeratosis, folliculitis and furunculosis with large numbers of nematode larvae of 25–40 μm of diameter within hair follicles were present. The Pelodera strongyloides dermatitica strain from the first verified case in Finland has been maintained in ordinary blood agar in our laboratory since 1975. Light microscopy (LM and scanning electron microscopy (SEM studies were employed to obtain detailed morphological information about the causative agent. The rhabditiform oesophagus at all developmental stages, the morphology of the anterior end of the nematode, copulatory bursa and spicules of the male and the tail of the female were the most important morphological features for identifying P. strongyloides. Conclusion These cases show that Pelodera dermatitis occurs in Finland, and also farther north than described earlier in the literature. This condition should be considered when a dog living outdoors has typical skin lesions situated at sites in contact with the ground as the main presenting clinical feature. The fastest and

    Full Text Available Background: Scabies is a highly contagious and intensely pruritic parasitic infestation. It is a re-emerging infection in the new millennium especially with HIV pandemic and a significant health problem in developing countries. Various treatment modalities have been used since time immemorial but the search for an ideal scabicide is ongoing. Aims: In this study, we compared the therapeutic efficacy of single application of topical 5% permethrin with oral ivermectin (200 μg/kg/dose in a single-dose and a two-dose regimen in patients with scabies. Methods: 120 clinically diagnosed cases of scabies (>5 years of age and/or >15 kg were randomized into three treatment groups A, B, C of 40 patients each; receiving either topical 5% permethrin (group A or oral ivermectin (200 μg/kg/dose in a single dose (group B or double dose regimen (group C repeated at 2 weeks interval. Patients were followed up at 1, 2, and 4 weeks interval. At each visit, cure rate (>50% improvement in lesion count and pruritus and negative microscopy was assessed and compared. Results: Cure rate in three treatment groups at the end of 4 weeks was 94.7% (A, 90% (B, 89.7%(C, and thus all three treatment modalities were equally efficacious. However, at 1 week follow up, group A patients reported better improvement in both lesion count and pruritus. Conclusions: Both permethrin and ivermectin in both single and two dose regimen are equally efficacious and well tolerated in scabies. However, permethrin has a rapid onset of action.

    Atopic dermatitis (AD) is a chronic, pruritic immune-mediated inflammatory dermatosis characterized by a T helper 2 (Th2) immune response phenotype and may be associated with systemic inflammation. Dupilumab is an interleukin 4 (IL-4) receptor α-antagonist that inhibits IL-4 and IL-13 signaling through blockade of the shared IL-4α subunit. Blockade of IL-4/13 is effective in reducing Th2 response. Dupilumab has recently been approved in the United States and Europe for the treatment of adult patients with moderate-to-severe AD. Clinical trials have shown that adults with moderate-to-severe AD who receive weekly or biweekly dupilumab injections have significantly improved clinical and patient-reported outcomes, including Eczema Area Severity Index, SCORing Atopic Dermatitis, Dermatology Life Quality Index, and itch Numeric Rating Scale scores. Concomitant use of topical corticosteroids along with dupilumab results in a greater improvement in signs and symptoms of AD than with use of dupilumab alone. Biomarker analyses show that dupilumab modulates the AD molecular signature and other Th2-associated biomarkers. Common adverse events reported in the clinical trials were nasopharyngitis, upper respiratory tract infection, injection site reactions, skin infections, and conjunctivitis. These were mild-to-moderate in nature, and overall rates of adverse events occurred with similar frequency between the treatment and placebo groups. There were no significant serious safety concerns identified in phase III clinical trials. Dupilumab, as monotherapy or with concomitant use of topical corticosteroids, can significantly improve clinical outcomes and quality of life in patients suffering from moderate-to-severe AD. Ongoing studies of dupilumab will help determine the clinical efficacy and safety profile of its long-term use. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Both humans and their most important domestic animals harbor IgE and a similar IgE receptor repertoire and expression pattern. The same cell types are also involved in the triggering or regulation of allergies, such as mast cells, eosinophils or T-regulatory cells. Translational clinical studies in domestic animals could therefore help cure animal allergies and at the same time gather knowledge relevant to human patients. Dogs, cats and horses may spontaneously and to different extents develop immediate type symptoms to pollen allergens. The skin, nasal and bronchial reactions, as well as chronic skin lesions due to pollen are in principle comparable to human patients. Pollen of various species most often causes allergic rhinitis in human patients, whereas in dogs it elicits predominantly eczematous lesions (canine atopic dermatitis), in horses recurrent airway obstruction or hives as well as pruritic dermatitis, and in cats bronchial asthma and so-called cutaneous reactive patterns (eosinophilic granuloma complex, head and neck pruritus, symmetric self-induced alopecia). In human allergy-specific IgE detection, skin tests or other allergen provocation tests should be completed. In contrast, in animals IgE and dermal tests are regarded as equally important and may even replace each other. However, for practical and economic reasons intradermal tests are most commonly performed in a specialized practice. As in humans, in dogs, cats and horses allergen immunotherapy leads to significant improvement of the clinical symptoms. The collected evidence suggests that canines, felines and equines, with their spontaneous allergies, are attractive model patients for translational studies.

    The attraction of novel foods proceeds alongside epidemic cardiovascular disease, diabetes, obesity, and related risk factors. Dieticians have identified chia ( Salvia hispanica ) as a product with a catalog of potential health benefits relating to these detriments. Chia is currently consumed not only as seeds, but also as oil, which brings about similar effects. Chia seeds and chia seed oil are used mainly as a food commodity and the oil is also used popularly as a dietary ingredient used in various dietary supplements available in the U. S. market. Chia seed is rich in α -linolenic acid, the biological precursor to eicosapentaenoic acid, a polyunsaturated fatty acid, and docosahexaenoic acid. Because the body cannot synthesize α -linolenic acid, chia has a newfound and instrumental role in diet. However, the inconclusive nature of the scientific community's understanding of its safety warrants further research and appropriate testing. The focus of this work is to summarize dietary health benefits of S. hispanica seed and oil to acknowledge concerns of adverse events from its ingestion, to assess current research in the field, and to highlight the importance of quality compendial standards to support safe use. To achieve this end, a large-scale literature search was partaken on the two well-known databases, PubMed and SciFinder. Hundreds of articles detailing such benefits as decreased blood glucose, decreased waist circumference and weight in overweight adults, and improvements in pruritic skin and endurance in distance runners have been recorded. These benefits must be considered within the appropriate circumstances. Georg Thieme Verlag KG Stuttgart · New York.

    Systemic antagonists of the histamine type 1 and 2 receptors (H1/2r) are widely used as anti-pruritics and central sedatives, but demonstrate only modest anti-inflammatory activity. Because many inflammatory dermatoses result from defects in cutaneous barrier function, and because keratinocytes express both Hr1 and Hr2, we hypothesized that H1/2r antagonists might be more effective if they were used topically to treat inflammatory dermatoses. Topical H1/2r antagonists additively enhanced permeability barrier homeostasis in normal mouse skin by the following mechanisms: (i) stimulation of epidermal differentiation, leading to thickened cornified envelopes; and (ii) enhanced epidermal lipid synthesis and secretion. As barrier homeostasis was enhanced to a comparable extent in mast cell-deficient mice, with no further improvement following application of topical H1/2r antagonists, H1/2r antagonists likely oppose mast cell-derived histamines. In four immunologically diverse, murine disease models, characterized by either inflammation alone (acute irritant contact dermatitis, acute allergic contact dermatitis) or by prominent barrier abnormalities (subacute allergic contact dermatitis, atopic dermatitis), topical H1/2r agonists aggravated, whereas H1/2r antagonists improved, inflammation and/or barrier function. The apparent ability of topical H1r/2r antagonists to target epidermal H1/2r could translate into increased efficacy in the treatment of inflammatory dermatoses, likely due to decreased inflammation and enhanced barrier function. These results could shift current paradigms of antihistamine utilization from a predominantly systemic to a topical approach.

    The pruritic skin disease scabies is caused by the burrowing of the itch mite Sarcoptes scabiei (De Geer). It is difficult to diagnose this disease because its symptoms often resemble those of other skin diseases. No reliable blood or molecular diagnostic test is available. The aim of this project was to begin to characterize the scabies proteome to identify scabies mite proteins, including those that may be useful in the development of a diagnostic test or vaccine. Various scabies mite extracts were separated by two-dimensional electrophoresis, and 844 Coomassie Blue-stained protein spots were excised, subjected to trypsin digestion, and analyzed by Matrix Assisted Laser Desorption/Ionization Time-Of-Flight/Time-Of-Flight (MALDI-TOF/TOF) mass spectrometry (MS). Tryptic fragment sequences determined by MS were searched against the recently completed S. scabiei annotated genome, leading to the identification of >150 proteins. Only 10 proteins hit to previously identified scabies proteins including actin, tropomyosin, and several ABC transporters. Thirteen proteins had homology to dust mite allergens (members of groups 8, 10, 13, 17, 20, 25, and 28). Most other sequences showed some homology to proteins in other mites and ticks including homologs of calmodulin, calreticulin, lipocalin, and glutathione-S-transferase. These data will now allow the identification of the proteins to which scabies patients produce antibodies, including those that may be good candidates for inclusion in a diagnostic test and vaccine. © The Authors 2016.

    Introduction: Phenytoin is one of anticonvulsant drugs (AC) which together with the Corticosteroids are used frequently in patients with intracranial tumors either early or metastatic; the association of treatments can cause adverse effects within which are skin reactions called erythema multiforme (EM) syndrome Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) whose incidence is 5 to 10%, with an increased risk are used when the AC associated with treatment with radiotherapy (RT).Case report: A 48 year old woman in whom primitive brain metastases were diagnosed breast cancer, so phenytoin, corticosteroids and performed RT presenting holoencefálica for such treatment maculo-papular skin reaction symmetrical onset zone Radiant treatment extension neck, thorax, abdomen and pelvis, oral mucositis, conjunctivitis and fever, which improved after stopping treatment altogether. Discussion: The clinical picture presented matches the description of the 30 Reported SJS / TEN in the literature with the use of AC and RT cases. The clinical course of the skin reactions in our patient represents the possible combined effect of phenytoin and RT as causative agents and analyzed the occurrence of side effects occurred in the third week of starting treatment with both therapeutic modalities such as what described in these reactions and improved frankly to stop treatment until disappear entirely. Cutaneous adverse reactions may occur as a complication severe in patients treated with RT and phenytoin and both treatments should suspend the first sign of side effects must continue once the patient recovered with AC radiant modifying drug treatment if necessary. There are differences of opinion regarding the prophylactic use of drug therapy in patients with AC intracranial tumors both early and metastatic. The American Academy of Neurology held a consensus in 2000 whose recommendations are non-routine use of AC in patients diagnosed intracerebral tumor that has not

    Full Text Available A neoplasia intra-epitelial vulvar grau III (NIV III se manifesta de modo visível, portanto, acessível à biópsia e, por conseguinte, ao diagnóstico histológico. Há duas formas precursoras do câncer vulvar: a NIV associada ao papiloma vírus humano (HPV e a NIV associada ao líquen simples crônico, hiperplasia de células escamosas e líquen escleroso, não tratados. Porém, pode existir sobreposição das duas formas. O termo papulose bowenóide, apesar de ser desencorajado, define uma das formas clínicas da NIV, que se apresenta como lesões pigmentadas, verruciformes, papulares e múltiplas. A NIV III está associada com HPV em mais de 80% dos casos e em 40% das vezes, nota-se envolvimento perianal. O seu tratamento é muito difícil e pode ocorrer recorrência em qualquer tempo e por muitos anos. Embora não exista tratamento padrão definido, os trabalhos apontam para a cirurgia, respeitando margem de segurança, como o mais adequado.High-grade vulvar intraepithelial neoplasia (VIN III is a visible lesion; therefore, it is accessible to biopsy and thus, to a histological diagnosis. There are two forms of vulvar cancer precursors: VIN caused by human papillomavirus (HPV and VIN associated with untreated lichen simplex chronicus, squamous cell hyperplasia, and lichen sclerosus. There may be overlap of the two forms. The term bowenoid papulosis, although discouraged, identifics a clinical form of VIN III. Such lesion appears as pigmented, wart-like growths or papules. VIN III is associated with HPV in more than 80% of the cases, and there is perianal involvement in 40% of the times. Vulvar intraepithelial neoplasia is difficult to cure and relapses can occur at any time for many years. Although there is no defined standard treatment, studies point to surgery, respecting a free margin, as the most adequate one.

    Full Text Available Abstract Background Germline mutations in the folliculin (FLCN gene are associated with the development of Birt-Hogg-Dubé syndrome (BHDS, a disease characterized by papular skin lesions, a high occurrence of spontaneous pneumothorax, and the development of renal neoplasias. The majority of renal tumors that arise in BHDS-affected individuals are histologically similar to sporadic chromophobe renal cell carcinoma (RCC and sporadic renal oncocytoma. However, most sporadic tumors lack FLCN mutations and the extent to which the BHDS-derived renal tumors share genetic defects associated with the sporadic tumors has not been well studied. Methods BHDS individuals were identified symptomatically and FLCN mutations were confirmed by DNA sequencing. Comparative gene expression profiling analyses were carried out on renal tumors isolated from individuals afflicted with BHDS and a panel of sporadic renal tumors of different subtypes using discriminate and clustering approaches. qRT-PCR was used to confirm selected results of the gene expression analyses. We further analyzed differentially expressed genes using gene set enrichment analysis and pathway analysis approaches. Pathway analysis results were confirmed by generation of independent pathway signatures and application to additional datasets. Results Renal tumors isolated from individuals with BHDS showed distinct gene expression and cytogenetic characteristics from sporadic renal oncocytoma and chromophobe RCC. The most prominent molecular feature of BHDS-derived kidney tumors was high expression of mitochondria-and oxidative phosphorylation (OXPHOS-associated genes. This mitochondria expression phenotype was associated with deregulation of the PGC-1α-TFAM signaling axis. Loss of FLCN expression across various tumor types is also associated with increased nuclear mitochondrial gene expression. Conclusions Our results support a genetic distinction between BHDS-associated tumors and other renal

    Full Text Available Although usually considered a non-pathogenic parasite in parasitological textbooks, Demodex folliculorum has been implicated as a causative agent for some dermatological conditions, such as rosacea-like eruptions and some types of blepharitis. Several anecdotal reports have demonstrated unequivocal tissue damage directly related to the presence of the parasite. However, this seems to be exceedingly rare, in contrast with the marked prevalence of this infestation. We have had the opportunity to observe one of such cases. A 38-year-old woman presented with rosacea-like papular lesions in her right cheek. Histopathological examination revealed granulomatous dermal inflammation with a well-preserved mite phagocytized by a multinucleated giant cell. This finding may be taken as an evidence for the pathogenicity of the parasite, inasmuch as it does not explain how such a common parasite is able to produce such a rare disease.Embora geralmente considerado um parasita não patogênico nos livros-texto de parasitologia, Demodex folliculorum tem sido implicado como agente causal de algumas condições dermatológicas, como erupções tipo rosácea e alguns tipos de blefarite. Vários relatos isolados têm demonstrado alterações teciduais sem dúvida relacionadas diretamente à presença do parasita. Entretanto, esses achados são extremamente raros, ao contrário da enorme prevalência da infestação. Tivemos a oportunidade de observar um destes casos. Paciente do sexo feminino, com 38 anos, apresentou lesões papulosas rosaceiformes, na região zigomática direita. O exame histopatológico revelou inflamação dérmica granulomatosa, com um ácaro bem preservado, fagocitado por uma célula gigante. Esse achado pode ser considerado como evidência a favor da patogenicidade do parasita, embora não explique como um parasita tão comum pode ser capaz de produzir alteração tão rara.

    Dermatomyositis is an idiopathic connective tissue disease characterized by specific cutaneous findings and inflammatory lesions in the muscle biopsy. An association between dermatomyositis and malignancy, including breast, ovarian, lung and colon cancer was recognized many years ago, with an incidence of malignancy in approximately 20 % of cases. Dermatomyositis is hypothesized to be an autoimmune reaction against factors or hormones secreted by the tumor; however, the exact autoimmune mechanism of the disease pathogenesis remains unknown. Here we report a case of a woman with dermatomyositis who was diagnosed with lung adenocarcinoma in the setting of weight loss, progressive fatigue and muscle weakness. A 43-year-old Caucasian woman was referred to our hospital by her physician for suspected contact dermatitis since she described mild itching sensations in her arms and legs as her major symptom. A physical examination revealed erythematous papular lesions over her metacarpophalangeal and proximal interphalangeal joints together with a periungual involvement with redness, hyperkeratosis and capillary telangiectasia along the distal nailfolds on her hands. She was unaware of these features and they did not seem to bother her. A thorough examination of her medical history, however, revealed more symptoms. Pain and weakness in the muscles of her proximal extremities and neck flexor muscles led to difficulty in raising her arms and climbing stairs. At the same time she experienced swallowing difficulties and reported an uncharacteristic weight loss of 10 kg in the last 3 months. The results of laboratory tests showed increased values of serum creatine kinase and myoglobin. An electromyogram, a skin biopsy and a muscle biopsy confirmed the diagnosis of dermatomyositis. A computed tomography of her thorax showed a nodular mass in the upper lobe of her right lung. A histological examination of the lung biopsy showed an adenocarcinoma of moderate differentiation. She was

    Shave excision is an established surgical method for removing benign skin lesions for cosmetic and functional reasons. Usually superficial shave excision is performed with a common scalpel blade for the removal of papular nevi. However, there is little known about deep shave excision of macular melanocytic nevi with the razor blade technique. The present study was undertaken to evaluate the cosmetic outcome of deep shave excision of macular melanocytic nevi with the razor blade technique. Moreover, its potency for sufficient removal of these lesions was investigated. Within routine skin cancer screening 45 outpatients with a total of 77 macular melanocytic nevi were prospectively recruited. Deep shave excisions of these lesions were performed with a double-edged razor blade followed by chemical hemostasis. Histologically all specimens were processed and evaluated in a routine manner. After 6 months the physician and patients evaluated the shave sites for cosmetic outcome with a score graded from 1 to 4 (1 = excellent; 2 = good; 3 = moderate; 4 = poor). Histologically 88% (68 of 77) of the melanocytic lesions were described as completely excised and 60% (46 of 77) were diagnosed as atypical melanocytic nevi; 12% (9 of 77) of the nevi were incompletely excised on the depth. On average, the deep margin of the specimens (n = 77) was 0.5 mm (range 0-1.8 mm) and the lateral margin was 2 mm (range 0.3-8.2 mm). After 6 months 56 shave sites could be reassessed. We observed mild hypopigmentation in 52% (29 of 56), hyperpigmentation in 32% (18 of 56), and erythema in 23% (13 of 56). Recurrent nevi occurred in 13% (7 of 56). The evaluation of the cosmetic outcome by the patients (mean score 1.7) achieved better results than the evaluation by the physician (mean score 2.5). The cosmetic results showed no significant (P >.05) differences in various anatomic sites. Our data confirm that deep razor blade excision presents a highly useful and inexpensive method for the removal of

    Minoxidil is a direct-acting peripheral vasodilator for the treatment of symptomatic hypertension, or refractory hypertension associated with target organ damage, that is not manageable with a diuretic and two other antihypertensive drugs. The most frequent adverse events associated with minoxidil include hypertrichosis and cardiovascular events related to its powerful antihypertensive effect, and less frequently, rashes, bullous eruptions, and Stevens-Johnson syndrome (SJS). Evidence suggests that SJS and toxic epidermal necrolysis (TEN) are variants of a single disease with common causes and mechanisms, but differing severities. Epidermal detachment is mild in SJS, moderate in overlap SJS-TEN, and severe (> 30% of body surface area) in TEN. We describe a case of minoxidil-associated SJS that evolved into fatal TEN. A 69-year-old African-American woman with a history of chronic kidney disease was admitted to the hospital for a cerebrovascular accident and uncontrolled hypertension. On hospital day 12, oral minoxidil was added to her drug regimen. On day 23, she developed a maculopapular rash on her face that gradually diffused to her chest and back. Vesicles and papular lesions extended to her extremities and mucosal membranes; results of a skin biopsy revealed SJS. A positive Nikolsky's sign (blisters spread on application of pressure) was detected. On days 27-31, diffuse bullae developed with rash exacerbation. Skin detachment exceeded 30% and was consistent with TEN. The patient died on day 39. An evaluation of the causality and time course suggested that minoxidil was the most likely culpable drug, with a Naranjo adverse drug reaction probability scale score indicating that the likelihood of the association was possible (score of 3). The mechanism of this reaction has not been well elucidated. It may be related to an impaired clearance of the minoxidil metabolite, or an immune stimulation resulting in apoptosis and epidermis destruction. To our knowledge, this

    Lawrence Livermore National Laboratory (LLNL), in collaboration with the Department of Homeland Security (DHS) and the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Services (APHIS) has developed candidate multiplexed assays that may potentially be used within the National Animal Health Laboratory Network (NAHLN), the National Veterinary Services Laboratory (Ames, Iowa) and the Plum Island Animal Disease Center (PIADC). This effort has the ability to improve our nation's capability to discriminate between foreign animal diseases and those that are endemic using a single assay, thereby increasing our ability to protect food and agricultural resources with a diagnostic test which could enhance the nation's capabilities for early detection of a foreign animal disease. In FY2005 with funding from the DHS, LLNL developed the first version (Version 1.0) of a multiplexed (MUX) nucleic-acid-based RT-PCR assay that included signatures for foot-and-mouth disease virus (FMDV) detection with rule-out tests for two other foreign animal diseases (FADs) of swine, Vesicular Exanthema of Swine (VESV) and Swine Vesicular Disease Virus (SVDV), and four other domestic viral diseases Bovine Viral Diarrhea Virus (BVDV), Bovine Herpes Virus 1 (BHV-1), Bluetongue virus (BTV) and Parapox virus complex (which includes Bovine Papular Stomatitis Virus [BPSV], Orf of sheep, and Pseudocowpox). In FY06, LLNL has developed Bovine and Porcine species-specific panel which included existing signatures from Version 1.0 panel as well as new signatures. The MUX RT-PCR porcine assay for detection of FMDV includes the FADs, VESV and SVD in addition to vesicular stomatitis virus (VSV) and porcine reproductive and respiratory syndrome (PRRS). LLNL has also developed a MUX RT-PCR bovine assay for detection of FMDV with rule out tests for the two bovine FADs malignant catarrhal fever (MCF), rinderpest virus (RPV) and the domestic diseases vesicular stomatitis

    The variability in the clinical or pathological presentation of transmissible spongiform encephalopathies (TSEs) in sheep, such as scrapie and bovine spongiform encephalopathy (BSE), has been attributed to prion protein genotype, strain, breed, clinical duration, dose, route and type of inoculum and the age at infection. The study aimed to describe the clinical signs in sheep infected with the BSE agent throughout its clinical course to determine whether the clinical signs were as variable as described for classical scrapie in sheep. The clinical signs were compared to BSE-negative sheep to assess if disease-specific clinical markers exist. Forty-seven (34%) of 139 sheep, which comprised 123 challenged sheep and 16 undosed controls, were positive for BSE. Affected sheep belonged to five different breeds and three different genotypes (ARQ/ARQ, VRQ/VRQ and AHQ/AHQ). None of the controls or BSE exposed sheep with ARR alleles were positive. Pruritus was present in 41 (87%) BSE positive sheep; the remaining six were judged to be pre-clinically infected. Testing of the response to scratching along the dorsum of a sheep proved to be a good indicator of clinical disease with a test sensitivity of 85% and specificity of 98% and usually coincided with weight loss. Clinical signs that were displayed significantly earlier in BSE positive cases compared to negative cases were behavioural changes, pruritic behaviour, a positive scratch test, alopecia, skin lesions, teeth grinding, tremor, ataxia, loss of weight and loss of body condition. The frequency and severity of each specific clinical sign usually increased with the progression of disease over a period of 16-20 weeks. Our results suggest that BSE in sheep presents with relatively uniform clinical signs, with pruritus of increased severity and abnormalities in behaviour or movement as the disease progressed. Based on the studied sheep, these clinical features appear to be independent of breed, affected genotype, dose, route

    Full Text Available The African hedgehog is one of the newly imported exotic pets which have been observed with increasing regularity in veterinary clinics in Costa Rica. Despite their popularity, information about their diseases is scarce. Within skin diseases of hedgehogs, mange caused by Caparinia spp. is a common diagnosis in other countries. Two adult African hedgehogs, one male and one female, were brought to a private clinic in Heredia, Costa Rica, with chronic pruritic dermatitis, scabs, nearly complete loss of spines, lethargy, dehydration, and weight loss. During physical exam, deposits of dry seborrhea were taken and processed for diagnosis. Microscopic examination revealed psoroptid mites identified as Caparinia tripilis. This is the first report of the presence of Caparinia tripilis in Costa Rica and, to the authors' knowledge, the rest of Central America. O ouriço africano é um dos animais de estimação exótico, recém-importado que tem sido observado com maior regularidade nas clínicas veterinárias da Costa Rica. Apesar da sua popularidade, informações sobre suas doenças são escassas. Dentre as doenças de pele de ouriços, a sarna causada por Caparinia spp. é um diagnóstico comum nos outros países. Dois adultos ouriços africanos, um macho e uma fêmea, foram levados para uma clínica particular, em Heredia, Costa Rica, com a dermatite pruriginosa crônica, crostas, perda quase completa de espinhos, letargia, desidratação e perda de peso. Ao exame físico, os depósitos de seborreia seca foram retirados e processados para o diagnóstico. O exame microscópico revelou ácaros (psoroptidae identificados como Caparinia tripilis. Esse é o primeiro relato da presença de Caparinia tripilis na Costa Rica e, para conhecimento dos autores, o resto da América Central.

    Background Pruritic scabies lesions caused by Sarcoptes scabiei burrowing in the stratum corneum of human skin facilitate opportunistic bacterial infections. Emerging resistance to current therapeutics emphasizes the need to identify novel targets for protective intervention. We have characterized several protein families located in the mite gut as crucial factors for host-parasite interactions. Among these multiple proteins inhibit human complement, presumably to avoid complement-mediated damage of gut epithelial cells. Peritrophins are major components of the peritrophic matrix often found in the gut of arthropods. We hypothesized that a peritrophin, if abundant in the scabies mite gut, could be an activator of complement. Methodology/Principal Findings A novel full length scabies mite peritrophin (SsPTP1) was identified in a cDNA library from scabies mites. The amino acid sequence revealed four putative chitin binding domains (CBD). Recombinant expression of one CBD of the highly repetitive SsPTP1 sequence as TSP-hexaHis-fusion protein resulted in soluble protein, which demonstrated chitin binding activity in affinity chromatography assays. Antibodies against a recombinant SsPTP1 fragment were used to immunohistochemically localize native SsPTP1 in the mite gut and in fecal pellets within the upper epidermis, co-localizing with serum components such as host IgG and complement. Enzymatic deglycosylation confirmed strong N- and O-glycosylation of the native peritrophin. Serum incubation followed by immunoblotting with a monoclonal antibody against mannan binding lectin (MBL), the recognition molecule of the lectin pathway of human complement activation, indicated that MBL may specifically bind to glycosylated SsPTP1. Conclusions/Significance This study adds a new aspect to the accumulating evidence that complement plays a major role in scabies mite biology. It identifies a novel peritrophin localized in the mite gut as a potential target of the lectin pathway of

    Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by highly pruritic eczematous lesions that are commonly treated with topical corticosteroids and calcineurin inhibitors. Side-effects and safety concerns associated with these agents restrict their use, and new, safe treatment options are therefore needed. Recent reports suggest that serotonin, i.e. 5-hydroxytryptamine (5-HT) and the 5-HT2 receptor family may contribute to inflammation and pruritus in the skin. The objective of this particular study was to investigate the 5HT2B receptor antagonist AM1030 with respect to its anti-inflammatory profile and potential. AM1030 was tested in a set of distinct human and rodent in vitro and in vivo models, differing with respect to e.g. T cell involvement, triggering stimulus, main read-outs and route of drug administration. The in vitro systems used were staphylococcal enterotoxin A (SEA)-stimulated human peripheral blood mononuclear cells, lipopolysaccharide (LPS)-stimulated human primary monocytes, LPS-stimulated human THP-1 monocytes and LPS-stimulated mouse primary macrophages. The in vivo systems used were LPS- and SEA-induced cytokine production in the mouse, antigen-induced arthritis in the rat, glucose-6-phosphate isomerase-induced arthritis in the mouse and delayed-type hypersensitivity reaction in the mouse. In addition, different cell populations were analyzed with respect to their expression of the 5-HT2B receptor at the mRNA level. AM1030 significantly reduced both T cell-dependent and T cell-independent inflammatory responses, in vivo and in vitro. Due to the low or absent expression of the 5-HT2B receptor on T cell populations, the influence of AM1030 in T cell-dependent systems is suggested to be mediated via an indirect effect involving antigen-presenting cell types, such as monocytes and macrophages. Based on the wide range of model systems used in this study, differing e.g. with respect to species, T cell involvement, triggering

    Atopic dermatitis is an inflammatory, pruritic skin disease that often occurs in early infancy with a chronic course. However, a specific description of subtypes of atopic dermatitis depending on the timing of onset and progression of the disease in childhood is lacking. To identify different phenotypes of atopic dermatitis using a definition based on symptoms before age 6 years and to determine whether some subtypes are more at risk for developing other allergic diseases. The Protection Against Allergy Study in Rural Environments (PASTURE) is a European birth cohort where pregnant women were recruited between August 2002 and March 2005 and divided in 2 groups dependent on whether they lived on a farm. Children from this cohort with data on atopic dermatitis from birth to 6 years of age were included. Atopic dermatitis, defined as an itchy rash on typical locations from birth to 6 years. The latent class analysis was used to identify subtypes of atopic dermatitis in childhood based on the course of symptoms. Multivariable logistic regressions were used to analyze the association between atopic dermatitis phenotypes and other allergic diseases. We included 1038 children; of these, 506 were girls. The latent class analysis model with the best fit to PASTURE data separated 4 phenotypes of atopic dermatitis in childhood: 2 early phenotypes with onset before age 2 years (early transient [n = 96; 9.2%] and early persistent [n = 67; 6.5%]), the late phenotype with onset at age 2 years or older (n = 50; 4.8%), and the never/infrequent phenotype (n = 825; 79.5%), defined as children with no atopic dermatitis. Children with both parents with history of allergies were 5 times more at risk to develop atopic dermatitis with an early-persistent phenotype compared with children with parents with no history of allergies. Both early phenotypes were strongly associated with food allergy. The risk of developing asthma was significantly increased among the early

    Canine atopic dermatitis is a pruritic allergic skin disease. House dust mites have been identified as the main non-seasonal responsible agent. Unlike in human allergic patients, groups 1 and 2 antigens have been described as minor allergens in dogs, while groups 15 and 18 are considered the major allergens. Despite these differences, allergic dogs have traditionally been treated using extracts intended for human immunotherapy. To investigate the immunological characteristics and the allergen reactivity of dogs with atopic dermatitis using a Dermatophagoides farinae commercial extract. Eighteen dogs diagnosed with atopic dermatitis and 3 healthy control dogs from the Iberian Peninsula were included in the study. All the animals were older than 12 months, from both sexes and different breeds and showed positive specific IgE against D. farinae (>2500 ELISA Absorbance Units). The D. farinae allergenic extract used in this study was manufactured and characterized. The allergenic profile of the dogs was investigated by immunoblot and specific IgE, IgG, IgG1 and IgG2 measured by direct ELISA. Allergen identity was confirmed by immunoblot inhibition and mass spectrometry analyses. The results confirmed the relevance of groups 15 and 18 antigens, but also groups 1, 2 and other medium molecular weight allergens in the sensitization of dogs with atopic dermatitis. Immunoblot inhibition and mass spectrometry assays confirmed these results. Relevant allergens were quantified by scanning densitometry (Der f 1: 17μg/mg, Der f 2: 20.3μg/mg, Der f 15: 18.1μg/mg and Der f 18: 9.4μg/mg). Concerning immunoglobulins profile, differences in IgE and IgG1 levels were observed between non-atopic and atopic dogs. The commercial D. farinae extract characterized in this study contains the major allergens involved in the sensitization of dogs with atopic dermatitis, representing a suitable candidate for its use in the diagnosis and immunotherapy of mite allergic dogs.

    To investigate the spinal processing of cutaneous pruritic and algesic stimuli, single-unit recordings were made from wide-dynamic-range-type lumbar spinal dorsal horn neurons in pentobarbital-sodium-anesthetized rats. Neuronal responses were recorded to mechanical and noxious thermal stimuli, as well as to microinjection (1 microl) of histamine (0.01-10% = 9 x 10(-1)-9 x 10(-4) M), capsaicin (0.1% = 3.3 x 10(-3) M), or other algesic chemicals into skin within the receptive field via intracutaneously placed needles. Most (84%) of the 89 neurons responded to intracutaneous (i.c.) microinjection of histamine with a brief phasic discharge followed by an afterdischarge of variable (s to min) duration. Ten minutes after i.c. microinjection of histamine (but not NaCl), there was a significant increase in the mean area of the low-threshold (but not high-threshold) portion of unit mechanical receptive fields. However, responses to graded pressure stimuli were not significantly affected after histamine. Responses did not exhibit significant tachyphylaxis when histamine microinjections were repeated at 5- or 10-min intervals. Unit responses significantly increased in a dose-related manner to microinjection of histamine at concentrations ranging across 4 orders of magnitude. Within 30 s after i.c. microinjection of the H1 antagonist cetirizine, unit responses to i.c. histamine delivered at the same skin site were significantly attenuated. Unit responses to histamine, as well as to noxious thermal stimulation, were significantly reduced after systemic administration of morphine (3.5 mg/kg i.p.) in a naloxone-reversible manner. Application of a mechanical rub, scratch, or a noxious heat stimulus during the unit's ongoing response to i.c. histamine produced a brief and marked excitation, often followed by a period of reduced ongoing discharge. Unit responses to histamine were markedly suppressed by electrical stimulation in the midbrain periaqueductal gray. Most (79%) histamine

    Ultraviolet radiation (UVR)-emitting sunbeds for self-tanning purposes have been available for around two decades. Originally claimed to be safe by commercial interests, because new technology enabled the emission of mostly UVA (315-400 nm) radiation, rather than the more profuse UVB (280-315 nm) present with UVA in midday summer or tropical sunlight, these devices have now been demonstrated to have similar deleterious cutaneous effects. However, such effects have taken time to define, and sunbed operators have continued to advocate their equipment as safe, with a tendency to tan without the sunburn characteristic of sunlight exposure; now that it indeed appears that sunbed UVA, along with not inconsiderable amounts of UVB usually also emitted, is similarly damaging to sunlight, a recent move has been to produce lamps emitting truly sunlight-like radiation instead. UVB and UVA both apparently exert their effects mainly through cutaneous cellular DNA damage, probably particularly in the germinative basal cell layer, UVB very likely through direct absorption and UVA more through secondary photosensitisation effects. As a result, sunburn, a tissue repair process, is initiated, along with an immediate tanning effect in those who tan readily; the former reaction, which may vary from subclinical to severe, sometimes leads in excessive instances to a persisting cutaneous hypersensitivity, or very rarely in extreme cases a fatal outcome. Delayed tanning also occurs after UVR exposure, again as a result of cutaneous DNA damage, the latter more marked in the fair-skinned who are perhaps more likely to use sunbeds in the first place. In addition, a sunbed tan usually only mildly protects the skin against later sunlight-induced damage, while irregular patchy tanning, dryness and itching of the skin are also common outcomes, and induction of the unsightly, pruritic polymorphic light eruption and more severe potentially debilitating disorders such as lupus erythematosus are

    Cutaneous larva migrans (CLM) is a parasitosis frequently seen in persons who have travelled to tropical or subtropical regions and in those who have worked in contact with soil. The disease frequently develops due to Ancylostoma braziliensis and Ancylostoma caninum species. After penetrating the skin and entering the body, the hookworm larva proceeds to bore tunnels through the epidermis, creating pruritic, erythematous, serpiginous lesions. Secondary bacterial infections of the lesions can often be seen, especially on the legs and buttocks. In this article we presented three atypical local cases which have not been declared previously in our country. The first case, a 54-year-old male who was admitted to hospital in August with complaints of an obverse body rash and itching lasting for a week. Eruptions were observed over a small area on the right side of the abdomen, consisting of itchy, raised, erythematous, curvilinear string-like lesions. Moreover, no eosinophilia was detected in the patient, whose culture showed a growth of Streptococcus pyogenes. The patient was clinically diagnosed with CLM accompanied by secondary bacterial infection and treated for three days with 1 g of amoxicillin-clavulanic acid, mupirocin cream and albendazole 400 mg/d. Under this regime, the lesions were seen to decline. The second case, a 38-year-old male was also admitted in August, complaining of itching and redness on his body. The patient, whose blood count values were normal, exhibited itchy, raised, serpiginous string-like lesions located on the left side of his body. The patient, whose bacterial culture was negative, was clinically diagnosed as CLM and treated for three days with albendazole 400 mg/d and the lesions were seen to improve. The third case, a 23-year old male was admitted in September complaining of itching and redness on his neck. An itchy, crescent-shaped erythematous lesion was detected on his neck; bacteriological cultures and blood count were normal. The

    Introduction Chronic cutaneous lupus erythematosus (CCLE) usually presents as characteristic erythematous patches and infiltrated coin-shaped plaques. However, there are some atypical clinical variants that may mimic other dermatological conditions. Haroon et al. reported in 1972 an unusual presentation of CCLE with hypertrophic follicular scars seen in acne vulgaris. Acneiform presentation is one of the most rarely reported and one of the most confusing, as it resembles a very common inflammatory skin disease. A brief review of the literature using PubMed found only nine other reports. Case report A 32-year-old woman presented with two-year pruritic infiltrated acneiform and comedonal eruption on the right chin treated as acne with isotretinoin without improvement. On examination the patient presented with erythematous-infiltrated plaque, papules, open comedones, pitting scars and hypopigmented atrophic scars on the right chin area and scalp hair loss. An incisional skin biopsy on the chin and scalp lesions was performed and the anatomopathological and immunofluorescence exam showed findings that are consistent with CCLE. Additional tests ruled out systemic involvement. The patient was treated with prednisone and chloroquine diphosphate with great improvement. After four years the lesion is stable, with some scarring. Discussion In a literature review we found nine other cases of acneiform presentation of lupus erythematosus: Three cases were systemic lupus erythematosus (SLE) and seven others were diagnosed as CCLE (including our patient). All three patients who had SLE tested positive for antinuclear antibodies (ANA), and only one patient with CCLE, had a low titer of positive ANA (1:80). Ages varied from 24 to 60 years old, with a median of 32 years old, the same as our patient's age and consistent with the literature. Seven were females and three were males, with a ratio of 2.3:1. Most cases, such as our patient, showed acneiform lesions mainly on the face, a

    Canine atopic dermatitis (cAD) is a common chronic and pruritic skin disease in dogs. The development of cAD involves complex interactions between environmental antigens, genetic predisposition and a number of disparate cell types. The aim of the present study was to perform comprehensive analyses of peripheral blood of AD dogs in relation to healthy subjects in order to determine the changes which would be characteristic for cAD. The number of cells in specific subpopulations of lymphocytes was analyzed by flow cytometry, concentration of chosen pro- and anti-inflammatory cytokines (IL-4, IL-10, IL-13, TNF-α, TGF-β1) was determined by ELISA; and microarray analysis was performed on RNA samples isolated from peripheral blood nuclear cells of AD and healthy dogs. The number of Th cells (CD3(+)CD4(+)) in AD and healthy dogs was similar, whereas the percentage of Tc (CD3(+)CD8(+)) and Treg (CD4(+)CD25(+) Foxp3(+)) cells increased significantly in AD dogs. Increased concentrations of IL-13 and TNF-α, and decreased levels of IL-10 and TGF-β1 was observed in AD dogs. The level of IL-4 was similar in both groups of animals. Results of the microarray experiment revealed differentially expressed genes involved in transcriptional regulation (e.g., transcription factors: SMAD2, RORA) or signal transduction pathways (e.g., VEGF, SHB21, PROC) taking part in T lymphocytes lineages differentiation and cytokines synthesis. Results obtained indicate that CD8(+) T cells, beside CD4(+) T lymphocytes, contribute to the development of the allergic response. Increased IL-13 concentration in AD dogs suggests that this cytokine may play more important role than IL-4 in mediating changes induced by allergic inflammation. Furthermore, observed increase in Treg cells in parallel with high concentrations of TNF-α and low levels of IL-10 and TGF-β1 in the peripheral blood of AD dogs point at the functional insufficiency of Treg cells in patients with AD.

    Full Text Available BACKGROUND: Pruritic scabies lesions caused by Sarcoptes scabiei burrowing in the stratum corneum of human skin facilitate opportunistic bacterial infections. Emerging resistance to current therapeutics emphasizes the need to identify novel targets for protective intervention. We have characterized several protein families located in the mite gut as crucial factors for host-parasite interactions. Among these multiple proteins inhibit human complement, presumably to avoid complement-mediated damage of gut epithelial cells. Peritrophins are major components of the peritrophic matrix often found in the gut of arthropods. We hypothesized that a peritrophin, if abundant in the scabies mite gut, could be an activator of complement. METHODOLOGY/PRINCIPAL FINDINGS: A novel full length scabies mite peritrophin (SsPTP1 was identified in a cDNA library from scabies mites. The amino acid sequence revealed four putative chitin binding domains (CBD. Recombinant expression of one CBD of the highly repetitive SsPTP1 sequence as TSP-hexaHis-fusion protein resulted in soluble protein, which demonstrated chitin binding activity in affinity chromatography assays. Antibodies against a recombinant SsPTP1 fragment were used to immunohistochemically localize native SsPTP1 in the mite gut and in fecal pellets within the upper epidermis, co-localizing with serum components such as host IgG and complement. Enzymatic deglycosylation confirmed strong N- and O-glycosylation of the native peritrophin. Serum incubation followed by immunoblotting with a monoclonal antibody against mannan binding lectin (MBL, the recognition molecule of the lectin pathway of human complement activation, indicated that MBL may specifically bind to glycosylated SsPTP1. CONCLUSIONS/SIGNIFICANCE: This study adds a new aspect to the accumulating evidence that complement plays a major role in scabies mite biology. It identifies a novel peritrophin localized in the mite gut as a potential target of the

    Full Text Available Introduction . Dermatitis herpetiformis (Duhring disease is an autoimmune blistering subepidermal dermatosis characterized by pruritic polymorphic skin eruption accompanied by a clinically asymptomatic gluten-sensitive enteropathy. The etiopathogenesis of the disease is associated with the presence of antibodies against tissue and epidermal transglutaminase. Diagnosis is based on direct immunopathological examination in which granular IgA deposits on the top of dermal papillae are detected. Sulfones are effective in the therapy of skin changes. Objective . The aim of the study is to present difficulties in evaluation of clinical picture, diagnosis and treatment, and monitoring the safety of the therapy in Duhring disease on the basis of three own cases. Case report . Case 1. 37-year-old patient. Itchy skin lesions occurred in mid-2012 and have been treated until now with antihistamines and local corticosteroids without improvement. The diagnosis of dermatitis herpetiformis was established on the basis of direct immunopathology test. Treated with gluten-free diet and dapsone 100 mg/day with improvement. Case 2. 62-year-old patient, in whom the first itchy eruption appeared in October 2012. Treated with antihistamines and topical corticosteroids without improvement. In laboratory examinations elevated level of IgE and triglycerides was found. Histopathological and immunological examinations confirmed the diagnosis of dermatitis herpetiformis. Treated with gluten-free diet and dapsone 150 mg/day with improvement. Case 3. 58-year-old patient. The first changes of typical morphology appeared about 2 years ago. The patient was treated with antihistamines and corticosteroids without improvement. Laboratory tests confirmed the diagnosis of Duhring disease. The introduction of gluten-free diet and dapsone 100 mg/day caused regression of skin changes. Conclusions . Our cases, treated for a long time as eczematous changes, despite the lack of improvement

La fracción libre de estas hormonas es la que ejerce su función biológica, mientras que la mayor parte de la concentración total está ligada a proteínas transportadoras, formando un reservorio hormonal tiroideo.

    El estado hipermetabólico observado en el hipertiroidismo, variable en severidad de acuerdo con niveles hormonales, causa y edad, produce síntomas que pueden relacionarse con una actividad simpático-mimética excesiva y a un aumento del catabolismo. Aunque los tratamientos clásicos del hipertiroidismo incluyen las tioureas, el yodo radiactivo y la cirugía, preferidos en forma prioritaria de acuerdo con la causa y con la edad, en la mayoría de los casos debe realizarse un bloqueo beta-adrenérgico como tratamiento coadyuvante, precisamente para antagonizar la excesiva actividad simpático-mimética (1.

There were no primary clinical evidences of Lyme-simile disease in the patients under study. The sensitivity and specificity of the clinical diagnosis as opposed to the laboratory diagnosis was zero. There was no initial clinical suspicion of the disease in the 10 cases studied and followed up for two years that showed no evidence of cardiologic or neurological complications. This is the first study of Lyme-simile in Brazilian children. CONCLUSION: Prevalence of Lyme-simile disease was low, and it was not remembered at the initial diagnosis of those with skin rash. However, practical knowledge is necessary, demanding increased medical attention.

PATIENTS AND METHODS: Between March/2005 and September/2009, we observed 14 patients with a mean age of 59.6 years undergoing treatment with cetuximab (7 or erlotinib (7, due to lung(10 or colorectal cancer (4. We evaluated the interval between introduction of the drug and onset of symptoms, treatment response, and the clinical pattern of evolution of the cutaneous reaction retrospectively. RESULTS: Twelve patients presented papular-pustular eruption typically affecting the face, chest and back, which appeared in average 13.5 days after starting the drug treatment. The patients underwent oral treatment with minocycline or doxycycline and topical treatment with metronidazole, benzoyl peroxide and/or corticosteroids. All patients showed improvement of the lesions. Five patients presented periungual pyogenic granulomas, which were associated with paronychia in 4 cases, after an average of 8 weeks of treatment. There was improvement of the lesions with topical treatment (antibiotics, corticosteroids and antiseptics. Xerosis was observed in some patients. Other less frequent adverse side effects such as telangiectasia and angiomas, hair and eyelash alterations, and eruptive melanocytic nevi were also described. Treatment with epidermal growth factor receptor inhibitor was maintained in most patients. CONCLUSION: The increasing use of these targeted therapies requires knowledge of their adverse cutaneous side effects to ensure timely intervention in order to allow the continuation of the therapy

    Full Text Available During March to May 2000, 48 carcasses of semi-domesticated reindeer (Rangifer tarandus tarandus were collected on winter pastures and calving grounds from two herds in western Finnmark and two herds in eastern Finnmark, northern Norway. The animals were autopsied and blood and tissue samples were collected for serology (alphaherpes- and pestivirus; virus neutralization test and polymerase chain reaction (PCR; parapoxvirus; B2L gene investigations. Autopsy revealed that 39 of 48 animals (81% had died of emaciation. Parapoxvirus-specific DNA was detected in samples from 6 of 48 animals (12.5%; liver, parotid salivary gland and/or pulmonary lymph nodes. A DNA sequence of 376 base pairs from a PCR amplicon obtained from a liver sample from one animal showed 98-99% identity with orf virus strain Orf-11 and reindeer parapoxvirus isolates from Norway and Finland (1992 and 1994, 92-93% similarity with pseudocowpoxvirus and 87% similarity with bovine papular stomatitis virus. Alphaherpes- and pestivirus antibodies were detected in 10% and 33% of the animals, respectively. These results indicates that parapoxvirus, presumably orf-virus, is present among reindeer also in Finnmark, although contagious ecthyma has never been reported in reindeer in this important reindeer herding area. Furthermore, they show that herpes- and pestiviruses are still endemic in reindeer herds in Finnmark. The nature of these viruses and their impact on reindeer health and reproduction and reindeer herding economy should be further addressed, as well as the possibility that these viruses may be transferred between reindeer and domestic animals in this region.Abstract in Norwegian / Sammendrag: I løpet av perioden mars-mai 2000 ble 48 reinsdyrkadavre (Rangifer tarandus tarandus samlet inn fra vinterbeiter og kalvingsområder fra to flokker i Vest-Finnmark og to i Øst-Finnmark, Norge.

    Full Text Available RESUMO: Um animal da espécie canina, sexo feminino, raça Akita, de três anos de idade foi avaliado clinicamente, devido a dermatite e otite pruriginosas persistentes, com um ano de duração. O exame físico revelou seborréia gordurosa generalizada, crostas aderentes, alopecia focal, eritema, pápulas, liquenificação e hiperpigmentação, evidentes no dorso, cuja localização foi considerada atípica, além do ventre e da pele interdigital do membro pélvico direito, associada a otite externa bilateral com alterações similares. Foi feito o diagnóstico de malassezíase cutânea e otológica, por meio de microscopia em amostras obtidas com fita adesiva. Foi também evidenciada uma significativa redução nos níveis de zinco, através de dosagem sérica. Esse animal, que vinha sendo tratado sem sucesso com drogas fungicidas, respondeu com melhora evidente do quadro após quatro semanas de tratamento com um fármaco fungicida sistêmico, associado a suplementação dietética com um composto polivitamínico e mineral contendo alta concentração de zinco. Os resultados sugeriram que os baixos níveis de zinco tiveram um papel importante no estabelecimento da doença cutânea produzida pela Malassezia. PALAVRAS CHAVE: Malassezia., dematite, cão SUMARY: 3-year-old female Akita was clinically evaluated because of persistent pruritic dermatitis and otitis of one year’ duration. Physical examination revealed generalized waxy scale; adherent crusting; patchy alopecia; erythema; lichenification; and hyperpigmentation. The body regions most severely afected included the back, which was considered uncommon, the ventral region of the abdomen and the interdigital skin of the right pelvic limb. There was also bilateral otitis externa with similar lesions. The diagnostic of Malassezia-associated dermatitis and otitis was made by microscopic examination of skin

    The likelihood of a drug reaction with lamotrigine is increased by dose escalation that is too rapid or drug interactions that increase the concentration of lamotrigine. There is a well-documented interaction between valproic acid and lamotrigine in which lamotrigine levels are increased, subsequently increasing the risk of a drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. This syndrome is characterized by fever, lymphadenopathy, diffuse maculopapular rash, multivisceral involvement, eosinophilia, and atypical lymphocytes and has a mortality rate of 10-40%. We describe the first case, to our knowledge, of DRESS syndrome that was probably induced by a drug interaction between lamotrigine and ginseng. A 44-year-old white man presented to the emergency department after experiencing a possible seizure. His medical history included two other lifetime events concerning for seizures at ages 14 and 29 years old. After referral to the neurology clinic, he was diagnosed with generalized tonic-clonic seizure disorder, and lamotrigine was started with up-titration according to the drug's package insert to a goal dosage of 150 mg twice/day. The patient had also been taking deer antler velvet and ginseng that he continued during his lamotrigine therapy. On day 43 of therapy, the patient presented to the emergency department with a pruritic rash that had started on his extremities and spread to his torso. He was thought to have experienced a drug reaction to lamotrigine, and the drug was discontinued. Thirteen days later, the patient was admitted from the acute care clinic for inpatient observation due to laboratory abnormalities in the setting of continued rash, headache, and myalgias. His admission laboratory results on that day were remarkable for leukocytosis, with a white blood cell count up to 17.6 × 10(3) /mm(3) , with a prominent eosinophilia of 3.04 × 10(3) /mm(3) ; his liver enzyme levels were also elevated, with an aspartate

  13. Diagnosing symptomatic HIV infection and AIDS in adults.

    The US Centers for Disease Control in 1982 listed conditions and infections then associated with AIDS. That case definition, used as a model for many countries, was designed primarily for epidemiologic surveillance and now includes more than 20 conditions. The definition, however, requires diagnostic and laboratory technologies which are not always available in developing countries. The World Health Organization (WHO) therefore published the Bangui definition in 1985 which uses clinical criteria alone. Many developing countries have adapted this definition to the types of pathogens they encounter domestically. According to the AIDS clinical definition, the presence of generalized Kaposi sarcoma or cryptococcal meningitis is sufficient for the diagnosis of AIDS. AIDS is also diagnosed if at least two major signs and one minor sign are present in the absence of known causes of immunosuppression such as malnutrition. Major signs are fever for more than one month, loss of more than 10% of body weight, and diarrhea for more than one month. Minor signs include cough for more than one month, generalized pruritic dermatitis, recurrent herpes zoster or shingles, oropharyngeal candidiasis or thrush, chronic or aggressive ulcerative herpes simplex, and persistent generalized lymphadenopathy. WHO has also developed criteria for diagnosing symptomatic HIV infection as an aid to individual case management. These criteria, however, are not intended to replace the Bangui AIDS case definitions developed for epidemiological purposes. The diagnosis of symptomatic HIV infection is made through physical examination and the taking of a very detailed case history. In so doing, there may be cardinal, characteristic, and/or associated findings. Cardinal findings of HIV infection are Kaposi sarcoma, oesophageal candidiasis, cytomegalovirus retinitis, Pneumocystis carinii pneumonia, and Toxoplasma encephalitis. Characteristic findings include oral thrush in a patient not taking antibiotics

  14. AUTOIMMUNE EPIDERMAL BLISTERING DISEASES

    Full Text Available Autoimmune bullous skin diseases (ABDs are uncommon, potentially fatal diseases of skin and mucous membranes which are associated with deposits of autoantibodies and complement against distinct molecules of the epidermis and dermal/epidermal basement membrane zone (BMZ. These autoantibodies lead to a loss in skin molecular integrity, which manifests clinically as formation of blisters or erosions. In pemphigus vulgaris, loss of adhesion occurs within the epidermis. The pioneering work of Ernst H. Beutner, Ph.D. and Robert E. Jordon, M.D. confirmed the autoimmune nature of these diseases. Walter F. Lever, M.D. contributed significantly to our understanding of the histopathologic features of these diseases. Walter Lever, M.D. and Ken Hashimoto, M.D. contributed electron microscopic studies of these diseases, especially in pemphigus vulgaris and bullous pemphigoid. In bullous pemphigoid (BP, linear IgA bullous dermatosis, epidermolysis bullosa acquisita (EBA and dermatitis herpetiformis (DH, loss of adhesion takes place within or underneath the BMZ. Classic EBA demonstrates extensive skin fragility; DH is commonly associated with gluten-sensitive enteropathy, and manifests clinically with pruritic papulovesicles on the extensor surfaces of the extremities and the lumbosacral area. The clinical spectrum of bullous pemphigoid includes tense blisters, urticarial plaques, and prurigo-like eczematous lesions. Pemphigoid gestationis mostly occurs during the last trimester of pregnancy, and mucous membrane pemphigoid primarily involves the oral mucosa and conjunctivae and leads to scarring. Linear IgA bullous dermatosis manifests with tense blisters in a „cluster of jewels”-like pattern in childhood (chronic bullous disease of childhood and is more clinically heterogeneous in adulthood. Many of the autoantigens in these disorders are known and have been well characterized. ABDs may be influenced by both genetic and exogenous factors. The diagnoses of

    body weight, glomerulopathy, ocular lesions, epistaxis and lameness. Non pruritic skin lesions are the usual manifestation and several forms have been described, such as exfoliative dermatitis and alopecia, and ulcerative, nodular and pustular dermatitis. Seroepidemiological studies of canine leishmaniasis have revealed a large number of asymptomatic seropositive animals. Moreover in areas where leishmaniasis is highly endemic, high proportion of apparently healthy animals show low levels of anti-Leishmania antibodies. Others have regressive forms of the desease, and their antibody levels will decrease in the following months or years; still others maintain low levels of antibodies without developing the desease for many years. However, the total number of infected animals is unknown. Canine leishmaniasis is a major zoonosic parasitic disease, enzootic in the Mediterranean area, caused by the intracellular protozoan Leishmania infantum. The dog is the main reservoir host of the parasite. However, most infected dogs do not present any clinical signs, and there is evidence that Leishmania infection prevalence rates in areas of endemicity are higher than those ascertained by serological studies. Visceral leishmaniasis is becoming a real problem of public health because it is an opportunistic infection in immunocompromised patients and in human immunodeficiency virus-positive subjects. The detection of the extent of the infection, particularly among asymptomatic dogs, is of great importance for the control of leishmaniasis. PCR has been applied successfully in recent years to detect Leishmania spp. even in the cases with any of the clinical manifestation of leishmaniasis. Very recently, real-time PCR for Leishmania has been applied to evaluate the parasitic load of dog tissues both at the time of the diagnosis and during follow-up of the therapy and to measure cytokine mRNA levels in different clinical samples of infected and uninfected dogs.

    Full Text Available Dermatological inflammatory diseases such as atopic dermatitis, psoriasis and seborrhoeic dermatitis often affect the scalp and the eyebrows. Although there are many dosage forms available, these are particularly critical anatomic regions for application of topical formulations because of the presence of hair. Lotions are therefore the recommended type of drug delivery system for these areas. The presence of hair may limit the application and thus the acceptability of the formulation and its compliance. Because of its low apparent viscosity, lotion application is unpleasant. Gels, given their consistency and adhesiveness, are a suitable alternative to lotions in this situation. The aim of this study was to formulate a stable gel containing mometasone furoate, which is an anti-inflammatory and anti-pruritic corticosteroid, in order to improve topical treatment of scalp dermatitis. In this study, pharmaceutical development, physical-chemical characterization, stability and in vitro permeation studies were performed. In terms of the pH, viscosity, assay and macroscopic and microbiological properties, the gel was stable over the period of study. The in vitro permeation studies allowed the characterization of the mometasone furoate permeation profile for the gel through different membranes. Mometasone furoate presented a slow permeation through the skin. This gel appears safe for topical application.Afecções dermatológicas do tipo inflamatório como a dermatite atópica, psoríase e dermatite seborreica, afetam freqüentemente o couro cabeludo e sobrancelhas. Apesar de existirem várias formas farmacêuticas para o seu tratamento, apenas as loções são indicadas para estas zonas, mas devido à baixa viscosidade, a aplicação de loções torna-se desagradável. Os geles, pela maior consistência e capacidade de adesão, apresentam-se como alternativa nesta situação. Neste trabalho procedeu-se ao desenvolvimento galênico de um gel com furoato

Recovery in adult animals usually occurs in 8-15 days. Clinical signs for most serotypes are less dramatic in sheep and goats. Swine can develop very severe coronary band lesions and high mortality in piglets has been observed. One of the challenges of diagnosing FMD is that it may be clinically similar to several other vesicular or ulcerative diseases. FMD is clinically indistinguishable from Vesicular stomatitis, Swine vesicular disease and Vesicular exanthema of swine. It may also resemble Bovine viral diarrhea, Mucosal disease, Infectious bovine rhinotracheitis, Bluetongue, Bovine papular stomatitis, Bovine mammillitis and Rinderpest.

Quatrocentos indíviduos de 74 famílias, residentes nos bairros S. João, Araguaina Sul e Neblina foram entrevistados e sangrados, independentemente de terem adoecido ou não. Os soros tanto de adultos quanto de crianças de ambos os sexos foram usados para pesquisa de anticorpos inibidores da hemaglutinação (IH e IgM através de ensaio imunoenzimático (MAC ELISA. Nas casas onde haviam doentes no momento do inquérito, sangue total também foi colhido para tentativa de isolamento de vírus. O quadro clínico apresentado pelos pacientes foi caracterizado por febre, cefaléia, mialgias, artralgias e exantema do tipo máculo-papular não pruriginoso.

    Full Text Available A estefanofilariose é uma doença mundialmente distribuída e caracteriza-se por lesões na pele causadas por nematódeo do gênero Stephanofilaria. Nos bovinos manifesta-se por uma dermatite crônica associada com erupção papular progredindo para nódulos, alopecia e ulceração crostosa. Apesar de reconhecida há muitos anos, há poucos estudos e relatos sobre a mesma. A literatura é particularmente escassa no Brasil. Esse trabalho teve como objetivos investigar aspectos epidemiológicos e clínicos da estefanofilariose em vacas leiteiras naturalmente acometidas e comparar dois métodos para a confirmação do diagnóstico, o exame histopatológico e o exame direto. Foram investigados aspectos clínicos relacionados à ocorrência natural da estefanofilariose em 58 vacas de leite de sete rebanhos criados nos municípios de Santana do Itararé, PR e de Itaberá, SP durante o período de janeiro de 2006 a agosto de 2008. Dois métodos foram comparados para confirmação do diagnóstico a partir de tecido colhido por biópsia da borda das lesões, o histopatológico (n=24 e o exame direto do sedimento da solução salina isotônica na qual o tecido permaneceu embebido (n=20. A maior prevalência ocorreu de dezembro a março (57% e a maioria das vacas era lactante (87,9%. As lesões se localizavam nos quartos anteriores do úbere em seu aspecto cranial (96,7%, principalmente próximo à linha média (55%. A lesão típica tinha formato circular era ulcerada com crostas e exibia exsudato sero-sanguinolento. No exame histopatológico evidenciou-se uma dermatite crônica com infiltrado mononuclear e eosinofílico. A presença do parasita não foi detectada em nenhum dos cortes examinados. O exame direto possibilitou a demonstração do agente em todas as amostras examinadas, comprovando-se como um método eficiente para a confirmação do diagnóstico.Stephanofilariasis is a worldwide disease caused by the nematode Stephanofilaria that determines
