Certain nail changes are specific for various dermatological disorders. In addition, examination of nails may also provide an insight into more sinister systemic manifestations in the form of both subtle as well as specific changes. These findings may present as a defect of various anatomical components of the nail unit; nail matrix, nail plate and/or nail bed or vasculature. This article is an attempt to equip the dermatologists with a foresight to suspect and diagnose the unapparent systemic connotations that may be possible by a simple but detailed nail examination.

Flow-cytometric osmotic fragility test is the best possible single test followed by EMA for diagnosis of HS. A combination of FOFT and EMA can correctly diagnose 100% patients. These tests are likely to replace conventional OFTs in future.

Summary Akin to cervical cancer in sexually-active women, men who have sex with men (MSM) are predisposed to anal cancers, especially those with HIV co-infection. This cross-sectional study endeavored to assess the prevalence of anal dysplasia using Pap smears and p16 immunostaining amongst Indian MSM. A total of 31 consecutive HIV-positive and 34 HIV-negative MSM, from a cohort of sexually transmitted infection clinic attendees, underwent anal cytological evaluation with Pap smear and p16 staining. Chi square test and coefficient of correlation were used for comparison. Eighteen (27.7%) had abnormal anal cytology; increased in HIV-positive as compared to HIV-negative men (35% versus 20%, p = 0.180). Similarly, both low-grade (25.8% versus 17.6%) and high-grade lesions (8.3% versus 4.8%) were comparable in HIV-positive and HIV-negative group. Thirteen (20%) smears were p16-positive with a sensitivity and specificity for anal dysplasia of 72.3% and 100%, respectively. Anal cytology may be used to screen for anal dysplasia in MSM irrespective of HIV status. Furthermore, the addition of p16, with greater specificity for high-grade lesions, may improve diagnostic accuracy especially for high-grade lesions. A larger study to further corroborate these observations is warranted.
