RESUMO
BACKGROUND: Emerging evidence suggests that chronic urticaria (CU) is associated with chronic, low-grade, inflammatory process. OBJECTIVE: To evaluate the association between CU and metabolic syndrome and its components in a large community-based medical database. METHODS: A cross-sectional study of CU patients and matched controls was performed. CU was defined as eight urticaria diagnoses (with each two diagnoses registered within a period of 6 weeks) from 2002 to 2012. Data regarding the prevalence of metabolic syndrome, its components and possible complications were collected. RESULTS: The study included 11 261 patients with CU and 67 216 controls. In a univariate analysis, CU was significantly associated with higher body mass index (BMI) and a higher prevalence of obesity, diabetes, hyperlipidaemia, hypertension, metabolic syndrome, chronic renal failure and gout. Multivariate analysis demonstrated a significant association between CU and metabolic syndrome (OR = 1.12, 95% CI 1.1-1.2, P < 0.001) and its components - obesity (OR = 1.2, 95% CI 1.1-1.3, P < 0.001), diabetes (OR = 1.08, 95% CI 1.01-1.15, P = 0.001), hyperlipidaemia (OR = 1.2, 95% CI 1.1-1.2, P < 0.001) and hypertension (OR = 1.1, 95% CI 1.1-1.2, P < 0.001). CONCLUSIONS: CU patients may have one or more undiagnosed components of metabolic syndrome despite their young age. Thus, appropriate targeted screening is advised.

Rituximab has recently been reported in retrospective studies to be effective in pemphigus at the dosing schedule used for treating rheumatoid arthritis (RA) of two 1,000 mg infusions 2 weeks apart. While the effect of rituximab on B cells has been well described, its effect on global T cell function has not been assessed. Ten patients who received RA dosage rituximab were prospectively assessed for clinical response. Immunological response including autoantibody titers, CD20+ B cell, and CD4+ T cell counts was assessed pre- and post-treatment. The CD4+ T cell function was determined by a novel assay measuring intracellular ATP levels in response to mitogenic stimulus. At 6 months, 90 % of patients achieved remission. Disease control and remission were achieved at median times of 1 and 3.7 months, respectively. There was a 67 % relapse rate during an average follow-up of 22 months. Global CD4+ T cell numbers and function were preserved 3 months after rituximab. A single cycle of RA dosage rituximab with concomitant immunosuppression is effective in pemphigus. We did not find an effect on total CD4+ T cell numbers or function 3 months after treatment.

Pilonidal sinuses usually occur in the sacrococcygeal area in young men, and occasionally can be found in other ectopic sites. We present a retrospective case review on unusual locations of pilonidal sinuses in the past 4 years. The lesion sites were as follows: one on the penis, two on the scalp, two on the abdomen, one on the neck, two in the groin and two in the axilla. Abdominal and penile lesions are uncommon, but the other locations reported are unusually rare. To our knowledge, the groin has not been reported previously as a site of a pilonidal sinus, although the histological appearance of hidradenitis suppurativa may well resemble it. When trying to clarify the pathogenesis of these occurrences, we found that recurrent hair removal was a common characteristic of the patients we contacted, and this may have been the initiating trauma.

BACKGROUND: Previous studies have described factors determining non-attendance at dermatology appointments in small sample sizes. OBJECTIVE: To perform an analysis of factors associated with non-attendance in a dermatology clinic in a larger sample. METHODS: Factors determining non-attendance were examined in 52 604 consecutive first-time visits to a dermatology clinic over a period of 44 months. RESULTS: Non-attendance proportion was 27.6%. Among children, non-attendance was associated with waiting for an appointment < 7 days [odds ratio (OR), 1.44], Bedouin sector (OR, 1.30), rural Jewish sector (OR, 0.45) and the treating physician. Among adults, non-attendance was associated with female gender (OR, 1.08), age < 55 years (OR, 1.65), waiting time for an appointment < 7 days (OR, 1.44), timing of the appointment between 1 and 4 pm (OR, 1.13), Bedouin sector (OR, 1.63), rural Jewish sector (OR, 0.46) and the treating physician. CONCLUSION: Non-attendance is common among Bedouins, adult female patients and young adults and is more likely as waiting times become longer. Strategies to reduce non-attendance are needed.

BACKGROUND: Previous reports have shown an association between psoriasis and the metabolic syndrome, but there are only a few studies on the association between psoriasis and diabetes. OBJECTIVES: To study the association between psoriasis and diabetes. METHODS: A cross-sectional study was performed utilizing the database of Clalit Health Services (CHS). Patients who were diagnosed with psoriasis were compared with CHS enrolees without psoriasis regarding the prevalence of diabetes. Patients with diabetes were identified using the CHS chronic diseases registry. Chi-squared tests were used to compare categorical parameters. Logistic regression models were used for multivariate analyses. RESULTS: The study included 16 851 patients with psoriasis and 74 987 subjects without psoriasis (control patients). The proportion of diabetes was significantly higher in patients above 35 years (P < 0.05). The age-adjusted proportion of diabetes was significantly higher in psoriasis patients as compared to the control group [odds ratio (OR), 1.38, P < 0.05] and was similar in men and women (OR, 1.32, 1.45, respectively). A multivariate logistic regression model showed that psoriasis was significantly associated with diabetes, independently of age and gender (OR, 1.58, P < 0.001). CONCLUSIONS: Our study supports previous reports of an association between psoriasis and diabetes. Dermatologists taking care of patients with psoriasis should be aware of this association and advise the patients to reduce additional risk factors such as smoking, hypertension or dyslipidemia.

BACKGROUND: Previous reports have shown an association between inflammatory diseases such as systemic lupus erythematosus or rheumatoid arthritis and the metabolic syndrome. Recent data demonstrate that psoriasis is an inflammatory disease, suggesting that psoriasis may be one of the components of the metabolic syndrome. OBJECTIVE: To assess the association between psoriasis and the metabolic syndrome. METHODS: A cross-sectional study was performed utilizing the database of the Clalit Health Services. Case patients were defined as patients with a diagnosis of psoriasis vulgaris. Controls were randomly selected from the list of Clalit Health Services enrollees. The proportions of components of the metabolic syndrome (ischemic heart disease, hypertension, diabetes, obesity and dyslipidemia) were compared between case and control patients by univariate analyses. chi(2) tests were used to compare categorical parameters between the groups. Logistic and linear regression models served to measure the association between psoriasis and the metabolic syndrome. RESULTS: The study included 16,851 patients with psoriasis and 48,681 controls. In the case group, there were 8,449 men (50.1%) and 8,402 women (49.9%), with a mean age of 42.7 years (SD = 20.3, range = 2-111). Diabetes mellitus was present in 13.8% of the patients with psoriasis as compared to 7.3% of the controls (p < 0.001). Hypertension occurred in 27.5% of the patients with psoriasis and in 14.4% of the controls (p < 0.001). Obesity was present in 8.4% of the patients with psoriasis as opposed to 3.6% of the controls (p < 0.001). Ischemic heart disease was observed in 14.2% of the patients with psoriasis as compared to 7.1% of the controls (p < 0.001). Multivariate models adjusting for age, gender and smoking status of the patients demonstrated that psoriasis was associated with the metabolic syndrome (OR = 1.3, 95% CI = 1.1-1.4), ischemic heart disease (OR = 1.1, 95% CI = 1.0-1.2), diabetes mellitus (OR = 1.2, 95% CI = 1.0-1.3), hypertension (OR = 1.3, 95% CI = 1.2-1.5) and obesity (OR = 1.7, 95% CI = 1.5-1.9). LIMITATIONS: The study is designed as a case-control study, thus an association alone was proven and not causality. CONCLUSION: Our findings demonstrate a possible association between psoriasis and the metabolic syndrome. Appropriate treatment of the metabolic syndrome may be an important part of the management of patients with psoriasis.

BACKGROUND: Nonattendance for appointments is an impediment to otolaryngology patient care worldwide. In a previous study of children attending an otolaryngology clinic, we observed that attendance was determined by the waiting time for an appointment and the timing of the appointment within the day. However, the factors that affect nonattendance in adults have not been well studied. OBJECTIVE: We aimed to investigate factors associated with nonattendance in adults visiting an otolaryngology clinic. METHODS: Nonattendance was observed for a period of one year in adult patients visiting an ambulatory otolaryngology clinic. The following parameters were also noted: age, gender, treating physician, waiting time and timing of the appointment. The chi-square test was used to analyse differences between categorical variables. The t-test was used to analyse differences between continuous variables. Logistic regression was used for multivariate analyses. RESULTS: The study assessed 8071 visits to the otolaryngology clinic. The overall proportion of nonattendance was 27.7 per cent. A multivariate logistic regression model demonstrated that nonattendance was significantly associated with the following factors: female gender, younger age, long waiting time for an appointment, timing of the appointment within the day and the treating physician. CONCLUSION: In adult otolaryngology patients, nonattendance was associated with patient-related factors and healthcare systems related factors alike. It is suggested that managed overbooking could be carefully introduced into otolaryngology patient scheduling.

BACKGROUND: Tinea pedis is a common infection in soldiers. However, prevalence and risk factors for tinea pedis in soldiers were investigated in only a few studies. OBJECTIVES: To investigate the prevalence and risk factors for tinea pedis in Israeli soldiers. METHODS: A cross-sectional study including interviews, clinical skin examination and mycological tests was performed in Israeli soldiers. The presence of tinea pedis was assessed using the Athlete's Foot Severity Index (AFSI), a scoring system that was developed in order to evaluate the presence and severity of tinea pedis. In soldiers with clinical evidence of tinea pedis (AFSI > 1), scrapings were taken for direct microscopic examination (20% KOH preparation) and fungal culture. Statistical analyses were performed using chi-square or Fisher's exact test for dichotomous variables (as needed), or t-tests for continuous variables. Logistic regression was used for multivariate analyses of dichotomous variables. RESULTS: Two hundred and twenty-three soldiers were included in the study: 205 men (91.9%) and 18 women (8.1%). Mean age was 19.6 years (SD 1.0 year). Clinical point prevalence was 60.1%. Mycological point prevalence was 27.3%. Further analyses were performed using the clinical point prevalence. Univariate analyses demonstrated that the prevalence of tinea pedis varied with the setting of military training (basic training: 70.3%, advanced infantry training: 81.5%, armor commander training: 56.4% and armor officer training: 34.8%) and was associated with male gender, frequency of sock changes and the length of military service. A multivariate analysis demonstrated that tinea pedis was associated with the setting of the military training (OR 1.6, 95% CI 1.2-2.1) and male gender (OR 4.3, 95% CI 1.4-13.8); however, there was no association with hygiene measures (e.g. frequency of changing socks or sleeping with socks) or the length of military service. CONCLUSION: Tinea pedis is highly prevalent in Israeli soldiers. Association of tinea pedis with the setting of military training suggests that contagious spread may be an important risk factor. We suggest that environmental interventions should be planned to in order to decrease the morbidity of tinea pedis among soldiers.

BACKGROUND: Previously, sponsored publications have shown that either terbinafine or itraconazole (pulse regimen) are effective for patients with toenail onychomycosis. However, independent comparative studies are lacking. OBJECTIVES: To objectively compare treatment with terbinafine and itraconazole in patients with toenail onychomycosis. METHODS: The effectiveness of terbinafine (250 mg/day 3 months) versus itraconazole pulse regimen (400 mg/day for the first week of each month, for three cycles) was retrospectively evaluated in patients with toenail onychomycosis using mycological tests and subjective outcome measures. Statistical analyses were performed using one-way analyses of variance (ANOVA) for continuous variables and Fisher exact tests for categorical variables. RESULTS: Included in the study were 117 patients (74 patients treated by terbinafine and 43 patients treated with itraconazole). Patients were examined at an average period of 20 months after the end of therapy. Mycological cure was observed in 70.6% and 62.8% of the patients who were treated by terbinafine or itraconazole, respectively (not statistically significant). Mean visual analogue scale assessment of treatment outcome was 79.9 mm (SD 24.7 mm) and 65.2 mm (SD 34.6 mm) for patients treated by terbinafine or itraconazole, respectively (p=0.008). When the results were stratified according to age and gender, it was observed that the advantage of terbinafine versus itraconazole retained statistical significance only for patients who were 55 years old and above, or females. CONCLUSIONS: Mycological cure proportions were not statistically significant between patients treated by terbinafine or itraconazole for toenail onychomycosis. However, better subjective outcome measures indicated an advantage for terbinafine over itraconazole, noticeable in females and patients 55 years old and above.

In this study, twenty-eight South Indian medicinal plants were screened for their anti-fungal activity against six species of fungi (Trichophyton mentagrophytes, T. rubrum, T. soudanense, Candida albicans, Torulopsis glabrata, and C. krusei). Three plant species extracts, Celastrus paniculatus, Eriodendron anfractuosum and Ficus glomerata showed inhibitory activity. An aqueous extract of galls of Terminalia chebula showed inhibitory effects on three dermatophytes (Trichophyton spp.) and three yeasts (Candida spp.). Seeds extract of T. chebula inhibited only the growth of T. glabrata. An aqueous extract of T. chebula showed inhibitory effects higher than those measured in ethanol extracts. It is therefore suggested that tannins are plausible candidates for the anti-dermatophytic effects of T. chebula. Chebulinic acid, a known tannin of T. chebula was tested and found not inhibitory, thus a search for the active compound is needed.

BACKGROUND: Psoriasis may have a severe impact on patients' quality of life (QOL) in several ways, an impact mediated by the mental or physical difficulties they have to deal with during the course of the disease and the various treatment regimens. In addition, psoriatic patients often suffer from experiences of stigmatization (EOS) related to the disease. OBJECTIVES: This study was designed to test the hypotheses that psoriasis patients report higher levels of stigmatization than a comparison group, and that their EOS play a role in mediating the impact of the severity of psoriasis on their QOL. METHODS: One hundred patients with psoriasis (study group) and 100 patients with mixed skin problems (comparison group) were matched according to age, sex and education. All subjects answered questionnaires on EOS and QOL. A dermatologist diagnosed the diseases and measured severity scores. The Psoriasis Area and Severity Index score was used for psoriasis and a linear severity score for the comparison patients. The mediating effect of EOS was analysed using structural equation modelling (SEM). SEM is a multivariate statistical method used to examine the consistency of a theory relating one group of variables (termed a 'latent construct') to another: in the present study, the relationship between EOS and QOL. RESULTS: Psoriatic patients were found to report significantly higher levels of EOS related to the disease, compared with the comparison group. No significant differences were found regarding QOL or severity of disease. Clinical severity of psoriasis was found to correlate negatively with QOL in psoriasis patients. EOS were found to have a complete mediating effect for the severity of disease on the QOL in patients with psoriasis. This result was not found among the comparison group patients. CONCLUSIONS: The results of this study indicate that psoriasis patients experience higher levels of stigmatization than do other dermatological patients, and that these EOS mediate the association between disease severity and patients' reported low levels of QOL. Treatment of psoriatic patients should consider these results and should include tools for psychosocial intervention.

We developed a simple scoring system to evaluate the severity of tinea pedis (Athlete's foot severity score, AFSS). The AFSS consists of a clinical evaluation, using a three-point scale, of erythema and scaling in the plantar and interdigital spaces of the feet, and counts of interdigital spaces involved. Each foot is evaluated separately. The validity of the AFSS was assessed in 224 soldiers of the Israel Defense Force using mycological cultures as the main outcome measure and subjective assessment of pruritus as the secondary outcome measure. Mycological examinations were performed in 106 patients who had clinical evidence of tinea pedis. AFSS was significantly associated with culture results (P<0.0001), as well as with the presence of pruritus (P=0.002), and pruritus scores (P=0.025). We conclude the AFSS is valid for the clinical evaluation of tinea pedis severity in military settings. The application of AFSS to civilian morbidity should be subjected to further evaluation.

Pyogenic granuloma is a benign vascular, inflammatory proliferation that appears following minor trauma in children. The exact pathogenesis of pyogenic granuloma is unknown, but its formation is closely related to minor trauma, chronic irritation, and hormonal influences. We present a unique case of a pyogenic granuloma that appeared in an infant following circumcision.

Cherry angiomas are the most common vascular proliferation; however, little is known about the pathogenesis and etiology of these lesions. We present two laboratory technicians who were exposed to brominated compounds for prolonged periods and who developed multiple cherry angiomas on the trunk and extremities. We suggest that the association between exposure to bromides and cherry angiomas should be investigated by a controlled study.

BACKGROUND: Multiple miliary osteoma cutis of the face represents primary extra-skeletal bone formation that arises within the skin of the face. METHODS: A 60-year-old woman with multiple miliary osteoma cutis of the face was treated by application of 0.05% tretinoin (all-trans-retinoic acid) cream nightly. RESULTS: After 3 months of therapy there were fewer papules and a decrease in size of remaining lesions. In a literature search, it was found that local application of tretinoin was successful and achieved a decrease in the number of papules over the face in all patients with multiple miliary osteoma cutis of the face; however, the length of time to achieve response varied from a few weeks to 6 months. CONCLUSION: It is suggested that local application of tretinoin cream should be considered in the therapy of multiple miliary osteoma cutis of the face, particularly when the lesions are small and superficial.
