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
