Gynecomastia is an enlargement of male breast resulting from a proliferation of its glandular component, and it is usually due to an altered estrogen-androgen balance. It should be differentiated from pseudogynecomastia, which is characterized by fat deposition without glandular proliferation and from breast carcinoma. Gynecomastia could be physiological in neonates and pubertal or pathological due to drug intake, chronic liver, or renal disease, hyperthyroidism, testicular or adrenal neoplasms, and hypogonadism whether primary, or secondary. Properly organized work-up is needed to reach the cause of gynecomastia. Here, we reported a case of a young Omani man with gynecomastia with the aim of creating awareness of the occurrence of Klinefelter’s syndrome (KS) in patients with gynecomastia, to observe any differences in clinical presentation of KS from those reported in the literature, and highlight the needed diagnostic work-up and treatment.
Objectives: This study aimed to identify the main barriers which prevent patients with diabetes mellitus from accepting insulin therapy. Methods: This cross-sectional study was conducted from May to December, 2019. Convenience sampling was used to recruit participants from three Diabetes Clinics in Muscat. Eligible participants were interviewed in person based on a pre-prepared questionnaire. The questionnaire, which was administered in Arabic, includes demographic data, and 19 specific items on barriers to insulin therapy. Results: A total of 201 participants (response rate 93 %) were enrolled in the study. The commonest barriers were as follows: concern of frequent blood glucose checking (36.3%), long- term injections (33.8%), side-effects of insulin (29.9%), and weight gain (29.4%). Needle phobia was considered as a barrier by only 9% of the participants. Overall, 125 (62.2%) of the participants were willing to initiate insulin therapy despite of the presence of these barriers and only 20 (10%) of the participants were influenced by these barriers to the degree that they would reject insulin therapy. Conclusion: The majority of our participants had no identifiable reasons which would stop them from accepting insulin therapy. Effective strategies should be developed to address each of the main barriers to improve acceptance and adherence to insulin therapy. Keywords: Diabetes; Insulin; Barrier; Needle phobia; Hypoglycemia; Weight gain.
abstract:Objectives: Glomerular filtration rate (GFR) is the best index of renal function and is frequently assessed by corrected creatinine clearance (CCL cr ). The limitations of CCL cr have inspired researchers to derive easy formulas to estimate GFR, with Cockcroft-Gault (C-G) and the modification of diet in renal disease (MDRD) being the most widely used. This study aimed to evaluate the validity of these equations by finding the relation between CCL cr and estimated GFR (eGFR) by C-G, modified C-G and MDRD equations. Methods: From 2007 to 2011, 158 subjects were analysed for serum creatinine and CCL cr at Bowsher Polyclinic, Muscat, Oman. The C-G equation was used to obtain eGFR C-G which was adjusted to body surface area (BSA) to obtain eGFR mC-G , and the MDRD equation was used to obtain eGFR MDRD . The eGFR MDRD , eGFR mC-G and eGFR C-G were then compared to CCL cr . Results: The eGFR MDRD , eGFR mC-G and eGFR C-G significantly correlated with CCL cr , with a slightly stronger correlation with eGFR MDRD (r = 0.701, 0.658 and 0.605, respectively). A receiver operating characteristic curve analysis showed that the diagnostic accuracy of eGFR MDRD for diagnosing chronic kidney disease (CKD) was higher than that of eGFR mC-G , which in turn was higher than that of eGFR C-G (area under the curve was 0.846, 0.831, and 0.791; cut-off limits were 61.9, 58.3 and 59.5, respectively). Conclusion: C-G and MDRD equations can be an alternative to the CCL cr test for assessing GFR, thus avoiding the need for the cumbersome and expensive GFR test. The MDRD formula had greater validity than the C-G equation and the C-G equation validity was improved by an adjustment to BSA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
