Hereditary spherocytosis (HS), a familial defect involving red blood cell (RBC) membrane proteins, is associated with reduced deformability, increased fragility, and progressive destruction of spherical cells. The present study focuses on three subjects of a family showing a history of repeated episodes of lethargy and pallor of unknown etiology. All patients displayed reticulocytosis and spherocytosis and one of them had anemia and splenomegaly. ⋯ Definitive diagnosis can be made on the basis of membrane protein analysis by quantitative sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Interestingly, all patients showed marked decrease in the protein 4.2 expression and therefore, HS was confirmed. This case report highlights the simultaneous occurrence of protein 4.2-dependent "typical" and "atypical" HS in a family and serves as a reminder to clinicians to consider RBC membrane disorders in patients presenting with suspicious and unexplained clinical signs.

Considering the importance of the increasing incidence of non-tuberculous mycobacteria, especially Mycobacterium abscessus worldwide, we conducted a study to evaluate the incidence of these diseases in our area. The aim of this study was to evaluate the prevalence of M. abscessus in patients with non-tuberculous mycobacteria. ⋯ In this study, we observed a high prevalence of Mycobacterium abscessus type 1 in patients. As the treatment protocol for non-TB mycobacteria is different from M. abscessus complex, the diagnosis of these species as soon as possible will be significant for physicians.

Papillary thyroid carcinoma (PTC) is a common subtype of thyroid carcinoma with a rising incidence rate. The purpose of this study was to provide a better understanding of age and PTC using the Surveillance, Epidemiology, and End Results (SEER) Program. ⋯ Age is a prognostic factor in OS and PCT specific survival. AJCC I stage and surgery treatment are also significant in predicting prognosis.

Biological and psychological factors contribute to cardiovascular disease (CVD). This study aimed to test the moderating effect of social loneliness in the relationship between worry and anger rumination, and CVD severity. ⋯ Based on the findings of this research, it can be concluded that along with biological factors, attention to the role of psychological factors of worry, anger rumination, and loneliness in preventive and therapeutic interventions related to CVD is a special necessity.

Iran is a great country with a long history of civilization and medicine. Following the increase in the prevalence of multiple sclerosis (MS), Iranian scientists and physicians started considering this disease and its outcomes in Iran. The first MS paper published by Iranian scientists dates back to 1963, when a case of hereditary spastic ataxia mimicking MS was reported. ⋯ Mohammad Ali Sahraian and was followed by the establishment of the first MS research center. MS Society is presently quite active and the Iranian MS congress is annually held in one of the Iranian universities to review the most recent achievements in the field of the disease. The present study aims to illustrate the history of the efforts made on the way, and attempts to introduce the people who took significant steps in this regard.
