Prayer marks (PMs) are commonly occurring dermatologic changes in muslims who pray and develop over a long period of time as a consequence of repeated and extended pressure. PMs need careful examination especially for patients with diabetes, who are more vulnerable due to predisposing factors such as venous insufficiency and peripheral neuropathy. A total of 166 patients with diabetes (150 males, 16 females) and 65 normal subjects from Bangladesh were examined for the appearance of PMs. Twenty-eight patients (16.9 %) and one normal subject (1.5 %) had PMs. The marks were not itchy or painful and they were observed on the dorsal aspect of the left foot, which was attributed to a more typical prayer position that placed pressure on the left foot. PMs are not a rare clinical entity among muslim patients with diabetes and most clinicians should be aware of it as it can be the predominant cause of an ulcer. © 2015, Springer Science+Business Media New York.

Background/Aim: Medullary thyroid carcinoma (MTC) originates from thyroid C-cells and is a calcitonin-secreting tumor. Calcitonin is also elevated in C-cell hyperplasia (CCH). The objective of the study was to determine the optimal basal (bCT) and peak stimulated calcitonin (psCT) cut-off value for differentiating MTC from CCH, and to examine the histological findings of thyroidectomy in patients with maximum psCT >100 pg/ml. Patients and Methods: Fifty-five patients had a maximum calcium-psCT >100 pg/ml and underwent total thyroidectomy. Results: A total of 20 patients were diagnosed with MTC and the remaining 35 with CCH. A bCT level >17.4 pg/ml and psCT level >452 pg/ml demonstrated the best sensitivity and positive predictive value for differenting MTC from CCH. Conclusion: The overlap of calcitonin levels between MTC and CCH reduces the accuracy of the calcium stimulation test. Remarkably, an appreciable number of patients with psCT levels >100 pg/ml harbor differentiated thyroid carcinoma of follicular origin. Source
