Onychomycosis is a common nail problem, accounting for up to half of all nail diseases. Several nail disorders may mimic the onychomycosis clinically. Therefore, a sensitive, quick, and inexpensive test is essential for screening nail specimens for the administration of the proper drug. The aim of this study was to compare 4 different diagnostic methods in the evaluation of onychomycosis and to determine their sensitivity, specificity, positive predictive value, and negative predictive value. In a cross-sectional study, nail specimens were collected from 101 patients suspected to have onychomycosis during a 14-month period. The nail specimens were examined using potassium hydroxide (KOH) 20 %, KOH-treated nail clipping stained with periodic acid-Schiff (KONCPA), and calcofluor white (CFW) stain, and grew a fungal culture. The culture was chosen as the gold standard for statistical analysis using the McNemar and chi-square tests. Out of 101 patients, 100 (99 %) patients had at least 1 of the 4 diagnostic methods positive for the presence of organisms. The positive rates for the fungal culture, KOH preparation, CFW, and KONCPA were 74.2, 85.1, 91.09, and 99.01 %, respectively. The sensitivity and negative predictive value of KONCPA was 100 %. KONCPA was the most sensitive among the tests and was also superior to other methods in its negative predictive value. KONCPA was easy to perform, rapid, and gave significantly higher rates of detection of onychomycosis compared to the standard methods of KOH preparation and fungal culture. Therefore, KONCPA should be the single method of choice for the evaluation of onychomycosis.
Background:most obsessive-compulsive disorder (OCD) patients meet psychiatrists 5 to 10 years after onset of OCD. Its relatively high prevalence ratio and the delay in seeking help suggest that patients with OCD may seek help at nonpsychiatric clinics. the present study was undertaken to provide some epidemiological data on the prevalence and severity of OCD in dermatological patients.Method:The participants included 265 consecutive patients with primary dermatologic chief complaint. They were visited by a dermatologist and diagnosis of dermatological lesion was done according to ICD-10. All patients were visited by a psychiatry resident and were screened for OCD using the structured clinical interview for DSM-IV-TR (SCID-I). If the diagnosis of OCD has been made, the Yale-Brown obsessive compulsive scale(Y-BOCS) was used to evaluate the severity of OCD. To analyze the data student t-test for quantitative variables and X2 tests for categorical variables.Results:From the total of 265 patients, 24(9.1%) met the DSM-IV-TR criteria for OCD and 9(37.5%) with OCD had previously been diagnosed with OCD, however, only three were treated pharmacologically. The most symptoms were pathological doubt (29.1%), fear of contamination(29.1%)and washing (54.16%). Severity of OCD according to Y-BOCS was evaluated among patients with OCD. Six (25%) were found with subclinical OCD, 11(45.8%) had mild OCD, six(25%) had moderate OCD, and one (4.2%) was detected with sever OCD.Conclusion:prevalence of OCD in dermatology clinic was higher compared with general population.
Introduction:Obsessive Compulsive Disorder (OCD) is an anxiety disorder which is usually characterized by two types of symptoms, namely.obsessions and compulsions.Objectives:Psychosomatic disorders include psycho-cutaneous disease, obsessive-compulsive disorde r(OCD) might be expressed as dermatological lesion and are known as dermo-OCD.Aims:The aim of this study were to determine the prevalence and severity of OCD and its relationship with dermatological disease in sari, Iran, 2011.Method:The sample consisted of 265 consecutively presenting dermatological patients who agreed to participate in the study, the subjects were assessed with structured clinical interview (SCID-I) by psychiatrist resident and also completed the yalebrown obsessive compulsive scale(Y-BOCS). T-test and chi-square were used to analyze of data.Results:Of the 265 dermatological patients, 24(9.1%) met DSM-IV criteria for OCD. Only 9(37.5%) of them had previousely been diagnosed as OCD. The most common obsession were washing 13(54.1) and pathological doubt 7 (25%), contamination7 (25%), checking 7(25%).Conclusion:There is a high prevalence of OCD in dermatological patients and with considerating of importance of OCD with comorbitiy of skin disease, dermatologist must be aware about relationship between two disorders and referring OCD patients to psychiatrist.
