This case describes a 42-year-old female with longstanding history of rheumatoid arthritis (RA) and Felty syndrome (FS). She presented with acute renal kidney failure, skin rash and hemoptysis. A clinical suspicion of small vessel vasculitis (SVV) was thought, serology was also positive for various markers of SVV. ⋯ It is challenging to manage a patient of RA, in the presence of Felty syndrome-related granulocytopenia and thrombocytopenia. Patient initially showed signs of improvement, but finally succumbed to complications of therapy. The case provides insight into the diagnosis and management of such cases.

Out of a panel of 37 candidate genes tested for linkage with polycystic ovary syndrome (PCOS), the strongest evidence of linkage was reported in the follistatin (FST) gene region. Subsequently, a couple of studies outside India investigated the FST gene for the presence of any mutations and its association with PCOS and the results were found to be largely inconsistent probably due to differences in the ethnic backgrounds and small sample sizes. ⋯ The occurrence of the exonic variants of FST gene seems to be dependent on the ethnic background of the subjects under study and its role in the PCOS pathophysiology cannot be established with hitherto available evidence.

Androgen-deprivation therapy is the mainstay of treatment for the management of advanced prostate carcinoma till transition to castration-resistant prostate carcinoma (CRPC). Recently, adrenal and intratumoral synthesis of androgens has been found to be the major cause for CRPC. ⋯ This article reviews the available evidence on efficacy and safety of this drug in CRPC. Searches of Pubmed, Cochrane database, Medscape, Google and clinicaltrial.org were made for terms like CRPC and abiraterone.

Over the last 20 years, the prevalence of healthcare-associated Clostridium difficile (C. diff) disease has increased. While multiple tests are available for the diagnosis of C. diff infection, enzyme immunoassay (EIA) testing for toxin is the most used. Repeat EIA testing, although of limited utility, is common in medical practice. ⋯ The utility of repeat testing was evident in outbreak settings, where the yield of repeat testing was 5%. Repeat C. diff testing for hospitalized patients has low clinical utility and may be considered in outbreak settings or when the pre-test probability of disease is high. Future studies should aim to identify patients with a likelihood of disease and determine the utility of repeat testing compared with empiric treatment.
