Prostate-specific antigen (PSA) is elevated in the serum of most men with prostatic diseases. Benign prostatic hyperplasia (BPH) is the commonest of these diseases. The degree of enlargement of the prostate may determine the amount of PSA elaborated. Several reports in some parts of the world have shown a significant correlation between prostate volume (PV) and PSA. However, only a few reports have been documented in Nigeria, especially in the South-South region. ⋯ There is a statistically significant correlation between PV and PSA (both free and total) in men with symptomatic histologically diagnosed BPH. This finding showed that larger benign prostate glands elaborated greater amounts of PSA. It may, therefore, be appropriate to say that it is not in all cases of elevated serum tPSA that the possibilities of malignancy or inflammation should be entertained.

Occupational lead (Pb) exposure causes multisystem effects at high and sustained low doses. However, there are inconsistencies in the dose-response effects on the thyroid and kidneys. ⋯ Though the mean levels of thyroid hormones and Cr were within their respective reference intervals, there was a preponderance of non-euthyroid status among participants in the present study with the majority of the participants falling within CKD grades 2 and 3.

Ocular perfusion pressure (OPP) has been suggested as a possible risk factor for the development and progression of primary open angle glaucoma (POAG). ⋯ OPP was lower in POAG subjects than in NG subjects. The observed relationship suggests that reduced OPP may play a role in the development of POAG.

To compare the effects of disinfectants on surface roughness of the conventional impression materials following chemical disinfection procedures. ⋯ Among all impression materials, polyvinyl siloxane showed the least surface roughness following disinfection procedures. Impression disinfectants that are specially designed for disinfecting dental impressions resulted in less surface roughness in all impression materials. With this study, it was aimed to obtain a smooth and clear model for the production of correct and compatible prostheses in the laboratory while at the same time purifying the impressions from microorganisms.

Review Case Reports
Primary extraskeletal Ewing's sarcoma presenting as an axillary mass: A case report and review of the literature.
Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor predominantly observed in adolescents and young adults, and is characterized by aggressive behavior. So far, only two cases of primary axillary soft tissue EES have been reported in the literature. One of them was a 29-year-old female patient who presented with a lump in her left axilla. ⋯ An immunohistochemistry (IHC) examination was positive for CD99 and negative for ER, PR, Her2neu, CK7, CK5/6, CD56, CD45, CK-pan, CKHMW, P63, desmin, S100, TdT, vimentin, myogenin, synaptophysin, and chromogranin A. The patient was diagnosed with primary axillary soft tissue EES and was started on neoadjuvant chemotherapy. Twelve months later, she is clinically free from the disease.
