Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a spectrum of acute, delayed-type hypersensitivity reactions that affect the skin and the mucous membranes. Medications are the culprit cause of these disorders in addition to infections and in very rare instances vaccinations. We report a case of TEN in a 49-year-old woman with no previous medical history. The disorder developed one week after receiving the first dose of COVID-19 vaccine with no other identifiable causes. The patient received two doses of tumor necrosis factor-alpha inhibitor (etanercept) and she stopped developing new lesions after two days of the initial dose; complete healing was observed after 22 days and no side effects were observed in our patient. This case demonstrates an extremely rare complication to the COVID-19 vaccine. The benefits of receiving the COVID-19 outweigh the potential risk.

Acquired hemophilia A (AHA) is an inhibitory coagulopathy that represents a rare variant of hemorrhagic syndromes. We present a case of idiopathic AHA in a 75-year-old male patient with a cutaneous hematoma that could be attributed to a recent COVID-19 vaccination. The aim of this report is to raise awareness of a possible association between AHA and COVID-19 vaccination and to review similar reported cases and management plans to prevent the development of possible morbidity and debilitating complications. This case illustrates an exceptionally rare side effect of the COVID-19 vaccination. The advantages of obtaining the COVID-19 vaccine outweigh the risks.

Highlights Schwannomas are benign tumors that commonly occur in the head and neck, mediastinum and extremities. Pelvic schwannomas are very rare. Patients with pelvic schwannomas have different clinical presentations. We reported 2 cases of schwannomas found at the presacral area. The mass was found incidentally in one of the cases and the patient was completely asymptomatic.

The concentrations of Ni, Cu, Zn, and Pb in human scalp hair of 281 individuals working in 10 Syrian industrial plants were determined using co-precipitation by ammoniumpyrolidinedithiocarbamate (APDC) method for total reflection X-ray fluorescence (TXRF) analysis. The results were compared to data obtained for a control group consisted of individuals working at the Syrian Atomic Energy Commission and also to data reported in the literature. The results given by the group of workers in battery plant showed that Pb concentration in human scalp hair samples were higher than those for control group, while some abnormal concentrations were obtained for Cu, Zn and Ni in cables, printing and battery plants, respectively. Normal concentrations of these elements were obtained for hair workers in olive oil, power stations, textile, and iron industrial plants. The relationships of Pb-Pb/Ni and Cu-Cu/Ni were plotted with correlation coefficients of 0.9937 and 0.9014, respectively. In general, the results showed that, the workers who were occupationally exposed to battery industrial pollution are at risk, followed by individuals in printing and cables industries, while the rest of workers in other industries are considered occupationally unexposed.

Background: Obesity has become a serious epidemic health problem in both developing and developed countries. There is much evidence that obesity among adolescents contributed significantly to the development of type 2 diabetes and coronary heart disease in adulthood. Very limited information exists on the prevalence of overweight, obesity, and associated metabolic risk factors among Syrian adolescents. Therefore, the purpose of this study was to determine the relationship between obesity determined by body mass index and the major metabolic risk factors among Syrian adolescents. Methods: A cross-sectional study of a randomly selected sample of 2064 apparently healthy Syrian adolescents aged 18 to 19 years from Damascus city, in Syria, was performed. Body mass index and blood pressure were measured. Serum concentrations of glucose, triglycerides, total cholesterol, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol were determined. Metabolic syndrome was defined using the national criteria for each determined metabolic risk factor. Individuals with a body mass index 25 to 29.9 were classified as overweight, whereas individuals with a body mass index ≥30 were classified as obese. A receiver operating characteristics curve was drawn to determine appropriate cut-off points of the body mass index for defining overweight and obesity, and to indicate the performance of body mass index as a predictor of risk factors. Results: The obtained data showed that blood pressure and the overall mean concentrations of fasting blood sugar, triglycerides, cholesterol, low-density lipoprotein-cholesterol, and triglycerides/high-density lipoproteincholesterol were significantly higher in overweight and obese adolescent groups (p <0.0001) in comparison with the normal group. Based on receiver operating characteristics calculation for body mass index and some metabolic risks, the data suggest the best body mass index cut-offs ranged between 23.25 and 24.35 kg/m

Proliferative lesions of the Brunner’s glands are uncommonly encountered lesions of the small intestine, originating from the deeply seated mucosal and submucosal Brunner’s glands, mainly in the duodenum. The vast majorities of these lesions are benign and include Brunner’s glands hyperplasia (adenomas/nodules) and hamartomas. The etiology and pathogenesis of these lesions are not fully understood, and the diagnosis can sometimes be challenging. We report a case of Brunner’s gland hamartoma in a 57-year-old man who presented with chronic dyspepsia, hematemesis and weight loss. Endoscopic and radiological investigations show a submucosal polypoid lesion at the first part of the duodenum. Routine endoscopic biopsies demonstrated normal duodenal mucosa. The lesion considered endoscopically unresectable and was surgically resected. Frozen section examination and intraoperative consultation showed unremarkable duodenal mucosa and histologically bland Brunner’s glands.

Prostate-specific antigen (PSA) has become the most useful serum tumor marker in adjunct to digital rectal examination (DRE) for the management of prostate cancer (PC). The currently cited reference range of normal PSA levels (between 0 and 4.0 ng/mL) is deficient in terms of both sensitivity and specificity. Age-adjusted PSA have been proposed as an alternative to serum PSA. The primary objective of the present study is to determine the age-specific PSA and the percentage of free PSA (%FPSA) in healthy Syrian men. A total of 3,000 healthy Syrian men over 40 years old participated in this study. All men were asked to have total serum (TPSA) and free PSA (FPSA) tested, a DRE, and, when recommended, a prostate biopsy. Serum TPSA levels correlated with age (r=0.30, p<0.001). The 95th percentile TPSA values ranged from 1.7 ng/mL in the age group 40-49 years to 5.8 ng/mL in the group 70-80 years. The general pattern for medians and the percentile values for FPSA across age groups were similar to those seen for TPSA concentrations (r=0.37, p<0.001). However, the %FPSA was fairly constant across age groups except for the higher ratios in the youngest age group. These findings confirm that the serum TPSA and FPSA levels correlate with age. Interestingly, however, Syrian men have lower PSA values compared with other races. Racial differences of PSA concentrations were observed. Our results may help increasing the sensitivity and specificity of PSA measurements in the diagnosis of prostate cancer in Syria and probably in the surrounding regions.
