Multicenter Study
The accuracy of HIV rapid testing in integrated bio-behavioral surveys of men who have sex with men across 5 Provinces in South Africa.
We describe the accuracy of serial rapid HIV testing among men who have sex with men (MSM) in South Africa and discuss the implications for HIV testing and prevention. This was a cross-sectional survey conducted at five stand-alone facilities from five provinces. Demographic, behavioral, and clinical data were collected. ⋯ False negatives were similar to true positives with respect to virological profiles. Overall accuracy of the RDT algorithm was high, but sensitivity was lower than expected. Post-HIV test counseling should include discussions of possible false-negative results and the need for retesting among HIV negatives.

Early type 2 diabetes mellitus (DM) may only require lifestyle modifications for glycemic control without the need for oral hypoglycemic agents (OHAs). Metformin is believed to improve cardiovascular outcomes in patients with DM, and it is considered to be a first-line therapy. However, it is unclear whether metformin is beneficial for patients with a new diagnosis of DM compared to those who do not need OHAs for glycemic control. ⋯ The metformin group also had an improved MACE-free survival profile from year 1 to year 12 (P < .001). In addition to lifestyle modifications, the patients with a new diagnosis of DM treated with metformin monotherapy had a lower MACE rate than those who did not take OHAs. Our findings suggest that metformin may be given early to patients with a new diagnosis of DM, even when they do not need OHAs for glycemic control.

This case may be due to basal ganglia dysfunction, which was probably caused by abnormal activation of dopamine 1-like receptor (D1R) boosted by pramipexole binding on dopamine 3-like receptor (D3R) in a situation where D3R was overexpressed by the chronic treatment of L-dopa. ⋯ Since the degree of overexpression of D3R is increased in a high dose of pramipexole, for patients with PD who are treated with L-dopa chronically, a new use of pramipexole and an increase in dose to alleviate the symptoms of PD should be implemented with caution while closely observing the occurrence of drug-induced complications such as dystonia and CRPS.

Case Reports
Myopathy in hyperthyroidism as a consequence of rapid reduction of thyroid hormone: A case report.
Myalgia and elevated creatine kinase (CK) are occasionally observed during the treatment of hyperthyroid patients. Relative hypothyroidism resulted from rapid thyroid hormone reduction had been promoted as a plausible cause of these myopathic changes, however rarely reported. ⋯ Differentiation of relative hypothyroidism from other causes of myopathy, especially with the effect of ATD, is important for clinical practice, although difficult in many cases.
