Shigellosis is one of the most important gastric infections caused by different species of Shigella, and has been regarded as a serious threat to public health. Lineage/sublineage profile of Shigella sonnei is strongly associated with the antibiotic resistance and population structure of this pathogen. In this study, we determined the phylogeny and antibiotic resistance profiles of S. sonnei strains, isolated from 1246 stool and 580 food samples, using multiplex PCR–HRMA genotyping and Kirby–Bauer disk diffusion methods, respectively. A total of 64 S. sonnei strains were isolated (13 food and 51 clinical isolates). Multiplex PCR–HMR assay was able to differentiate the lineages II and III, and sublineages IIIb and IIIc strains successfully considering the definite melting curves and temperatures. Lineage I and sublineage IIIa strain were not isolated in this study. We also demonstrated that most of the S. sonnei strains isolated from both food and clinical samples clustered within the lineage III and sublineage IIIc. Resistance against trimethoprim-sulfamethoxazole, tetracycline, chloramphenicol, and streptomycin antibiotics were the most prevalent phenotypes among the S. sonnei lineage III and sublineage IIIc strains.

Thymolipoma is a benign and rare tumor that could be found at any age. Thymolipoma associated with the myasthenia gravis, Graves disease, aplastic anemia, and hypogammaglobulinemia was reported previously, but in this case, thymolipoma is associated with lymphocytosis. A 6-year-old girl was brought to the hospital because of a chronic cough. Her evaluation revealed a 130 × 160× 160 mm fat-containing soft tissue mass arising from anterior mediastinum with complete left lung collapse and contralateral mediastinal shift. Her past medical history showed that she had been evaluated and treated unsuccessfully due to severe lymphocytosis two years earlier. Her peripheral blood and bone marrow cell morphology were normal; in contrast, blood cell count and CD flow cytometry showed severe lymphocytosis. The patient's tumor was excised entirely without any complications, and lymphocytosis resolved during the follow-up period. Because the T lymphocytes are developed in the thymus, and more than 80% of cells in CD flow cytometry were T lymphocytes, and the lymphocytosis resolved with tumor removal; therefore, the authors suggested that Thymolipoma could be associated with lymphocytosis.

The golden age of Islamic medicine (800 to 1300 CE) is a notable period in medical history. Medical education in this period of time was significant and systematic in Islamic territory. In the early Golden Age of Islamic Medicine, Abū Zayd Ḥunain ibn Isḥāq al-'Ibādī, an exceptional scholar and translator, emerged. He was known as Johannitius in medieval Europe. Al-Masā‘il fī al-tibb lil-Mutāllimīn ( Questions on Medicine for Students) was written by Hunain ibn Isḥāq. This book remains a definitive text on Islamic medicine and has been printed and published widely in Europe. Al-Masā‘il fī al-tibb is written in the style of questions and answers which is distinct from the conventional writing style of medical books on Islamic medicine. The current article reviews Al-Masā‘il fī al-tibb and its distinguishing style, the question and answer format. Today, the question-and-answer method is a popular method of medical education, and clinical teachers tend to use it in medical education because of the advantages it offers. The use of this method in Al-Masā‘il fī al-tibb for education and examination of medical students by Ḥunain ibn Isḥāq reflects a great improvisation in medical education and introduces him as the leading developer of the question-and-answer method in Islamic medical education.
