A statistically significant higher NAPSI score (P less then 0.05) was obtained by a dermoscope than by clinical examination. Salmon patch and splinter hemorrhage were better visualized using a dermoscope than by clinical evaluation (P less then 0.05). The duration of the disease had a strong positive correlation (R = 0.901) with the duration of nail involvement whereas there was a weak correlation between the duration of the disease and the clinical NAPSI (R = 0.23) and dermoscopic NAPSI (R = 0.28). A weak positive correlation (R = 0.3) was noted between the PASI and NAPSI scores. Conclusion Dermoscopy of nails proved to be an efficient, supportive, easy, noninvasive method that provides a better insight into the subtle nail changes in psoriatic patients, which may have been missed clinically.

Renal involvement in patients with psoriasis is sparsely studied and its association is still unclear. Aim The aim of this article was to study causal attributable renal involvement in patients with psoriasis and factors affecting the same. Methods Fifty patients with documented psoriasis were recruited after excluding any secondary causes of renal disease. They were subjected to routine investigations along with hs-CRP and specific investigations for kidney function including urine albumin creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR). The eGFR and ACR of the patients were compared with 50 age- and sex-matched controls. Association with any disease-related factors such as severity and duration were assessed. Renal biopsy was planned in patient with ACR >500 mg/g creatinine. Results The mean eGFR (IQR) (ml/min/1.73 m2) of tis aspect in further details. Limitation of the Study Sample size was small. Large-scale studies would be required to further substantiate these observations.

It is common in collective centers such as schools, garrisons, campuses and old age homes. Cryptotanshinone datasheet It is worldwide in distribution with no strict limitation with respect to age, gender and race. Aims Present study was conducted to investigate the socio-economic and lifestyle risk factors for head louse infestation in pediatric patients. Materials and Methods An observational descriptive study at a tertiary care hospital in rural Uttar Pradesh over a period of 1 year wherein measurement of disease/risk factors associated with head louse infestation was performed. It was carried out in all children between 5 and 15 years of age using a pre-validated questionnaire. The method of convenience sampling was used and multiple logistic regression was run to account for potential confounding variables using SPSS software. Results A total of 165 (71.1%) females and 67 (28.8%) males were infested. Most common age group affected was between 5 and 7 years where 97 (41.8%) children were infected. Ninety-five (40.9%) children were in fourth to seventh standards. Parents of 137 (59%) children were not formally educated. Eighty-one (34.9%) children had six members in the family while per capita income was between 5000 and 2500 in families of 139 (59.9%) children. Eighty-seven (37.5%) children had hair length up to shoulders. One twenty-eight (55.1%) children had no family member affected. Seventy-six (32.7%) children took bath twice a week only. Conclusion Social and economic factors as well as lifestyle and education level of patients play a significant role in epidemiology of head lice.

The present study was undertaken to assess the role of C. trachomatis in patients with ReA since such data is lacking from the Indian population. Materials and Methods PCR using specific primers for C. trachomatis was carried out from urine samples of 65 patients with ReA, 20 of other inflammatory arthritis, and 20 healthy controls. Results C. trachomatis DNA was detected from urinary samples with PCR in 24 (36%) of 65 ReA patients. PCR was negative in the patients of other inflammatory arthritis as well as in normal healthy control group. Out of the 24 patients with urinary PCR positivity, 14 (58.33%) were males and 10 (41.66%) were females. Conclusion Urinary PCR plays an important role in rapid diagnosis of ReA associated with C. trachomatis.

It is used for consultation, education, second opinion, and monitoring medical conditions. This article will review basic concepts, the integration of noninvasive imaging technique images, artificial intelligence, and the current ethical and legal issues.

It is characterized by brownish black discoloration of nail plate and is a common cause of nail plate pigmentation. The aetiology of melanonychia ranges from more common benign causes to less common invasive and in situ melanomas. Melanonychia especially in a longitudinal band form can be due to both local and systemic causes. An understanding of the epidemiology, pathophysiology and clinical details is necessary for adequate patient care and counseling. It not only helps in the early recognition of melanoma but also prevents unnecessary invasive work up in cases with benign etiology. An early diagnosis of malignant lesion is the key to favourable outcome. Though there are no established guidelines or algorithms for evaluating melanonychia, a systematic stepwise approach has been suggested to arrive at a probable etiology. We, hereby, review the aetiology, clinical features, diagnostic modalities and management protocol for melanonychia. Copyright © 2020 Indian Dermatology Online Journal.
