Onychoscopy, being handy, inexpensive, and noninvasive, has the potential to reduce the invasive procedures. Statistically significant patterns in DLSO and total dystrophic onychomycosis (TDO) are described in our study. Few new patterns have been described whose significance has to be tested by conducting larger sample size studies.

Background: Onychomycosis (OM) is a fungal infection of the finger or toenails caused by dermatophytes, yeasts, or nondermatophyte molds (NDMs) and can involve any component of the nail unit. OM, apart from being asymptomatic, is a chronic disease and warrants long-term treatment. Aims: The aim was to study the clinicoepidemiological features of OM and to evaluate the mycological and histopathological features among patients attending the dermatology outpatient department. Subjects and Methods: A cross-sectional hospital-based study was performed in 500 patients with symptoms related to the nails and nail folds. OM was confirmed in 284 patients by potassium hydroxide (KOH) mount, fungal culture, or biopsy. Descriptive analysis of the data was undertaken. Results: The study included 284 confirmed cases of OM of which 117 (41.1%) were positive for fungal elements by KOH mount, 168 (59.1%) samples showed positivity in fungal culture, and 62 (21.8%) samples had positive nail biopsy results. Distolateral subungual OM was the most common clinical type (47.6%). Among the fungal isolates, a predominance of dermatophytes was observed followed by yeasts and NDMs. The most common dermatophytic fungal isolate in the culture was Trichophyton rubrum (45%). Conclusion: Our study implies the importance of laboratory diagnosis of OM as it can mimic diverse nail disorders. As the role of NDMs and yeasts is on the rise for etiology of OM, investigations such as KOH examination, culture, or nail biopsy becomes essential for correct diagnosis and management.

Background: Iodine deficiency disorders are recognized as major public health problem in India and the simplest, most effective and inexpensive preventive method is the consumption of Iodized salt. The objective of this study is to estimate the prevalence of goitre among children aged 6 to 12 years in rural areas of Koppal district, to determine various factors associated with goiter among children, to estimate the level of urinary iodine excretion among urine samples collected from children and to estimate the level of iodine content among salt samples collected in the study setting.Methods: A cross sectional study was conducted for a duration of 6 months from June 2018 to November 2018 in rural areas of Koppal district among 3047 school children aged 6 to 12 years selected by cluster sampling technique. Goiter was detected and graded using standard techniques and the collected salt and urine samples were sent to MRHRU, Sirwar, Raichur for analysis. Data was collected using pretested and semistructured questionnaire and was analyzed using WHO Epi info software version 3.5.4.Results: The prevalence of goitre among school children in Koppal district was 442 (14.5%) and it was found to be significantly associated with age and source of drinking water. Majority i.e., 65.96% of urine samples had iodine content less than 100 µg/l and majority i.e., 79.15% of salt samples had iodine content less than 15 PPM.Conclusions: Goiter is mild public health problem in Koppal district with majority of urine samples excreting iodine below optimum levels and majority of salt samples being inadequately iodized.
