Symptomatic recurrence of SARS-CoV-2 infection in healthcare workers recovered from COVID-19.

There is rising concern that patients who recover from COVID-19 may be at risk of recurrence. Increased rates of infection and recurrence in healthcare workers could cause the healthcare system collapse and a further worsening of the COVID-19 pandemic. Herein, we reported the clinically symptomatic recurrent COVID-19 cases in the two healthcare workers who treated and recovered from symptomatic and laboratory confirmed COVID-19. We discuss important questions in the COVID-19 pandemic waiting to be answered, such as the protection period of the acquired immunity, the severity of recurrence and how long after the first infection occurs. We aimed to emphasize that healthcare workers should continue to pay maximum attention to the measures without compromising.

Contribution of Sonoelastography to Diagnosis in Distinguishing Benign and Malignant Breast Masses.

OBJECTIVES: The purpose of this study was to investigate the contribution of strain index measurements and a 5-point scoring method to diagnostic accuracy in differential diagnosis of benign and malignant solid breast masses and to compare the diagnostic performances of both methods. METHODS: Eighty female patients were included in this study. Before biopsy, all patients underwent ultrasound (US) and sonoelastographic examinations. The elastographic images of lesions were assessed according to the 5-point scoring method, and then elasticity scores were determined. Strain values of the masses and subcutaneous adipose tissue were measured. The diagnostic efficacies of B-mode US, sonoelastographic 5-point scoring, and strain index methods were compared with histopathologic findings. RESULTS: The mean age of the patients ± SD was 42 ± 13 years (range, 14-81 years). In histopathologic evaluations, 59 (74%) lesions were diagnosed as benign, and 21 (26%) were diagnosed as malignant. The mean strain index values were 10.45 ± 7.04 (range, 3.4-25.1) in malignant lesions and 2.88 ± 2.5 (range, 0.5-19.81) in benign lesions. The mean strain index for malignant lesions was significantly higher than that for benign lesions (P < .05). The highest sensitivity was found for B-mode US, and the highest specificity was found for the strain index. The diagnostic performance of the strain index was higher than that of the 5-point scoring method. CONCLUSIONS: The addition of a sonoelastographic examination to B-mode US prevents unnecessary biopsies. The strain index was found to be superior to the 5-point scoring method to a limited extent.

Arachnoid cysts with spontaneous intracystic hemorrhage and associated subdural hematoma: Report of management and follow-up of 2 cases.

Arachnoid cysts are one of the most frequently encountered intracranial space-occupying lesions in daily neurosurgery and neuroradiology practice. Majority of arachnoid cysts, particularly those of smaller sizes, have a benign uneventful lifetime course. Certain symptoms may indicate serious complications related to underlying arachnoid cysts. Hemorrhage is one of the most fearsome complications of arachnoid cysts and almost all reported cases in the literature have undergone surgical correction. In this study, we aimed to present clinical and radiologic follow-up findings in two adult cases of intracranial arachnoid cyst with spontaneous intracystic hemorrhage and associated subdural hematoma, one of which was successfully treated conservatively. In addition, we broadly summarized and discussed pertinent studies in the English literature.

Acute Pancreatitis and Gastroduodenal Intussusception Induced by an Underlying Gastric Gastrointestinal Stromal Tumor: A Case Report.

Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal system and comprise only 1% to 3% of all gastrointestinal tract tumors, with the majority of them arising in the stomach. In this report, we present the unique findings of a case of gastroduodenal intussusception caused by an underlying gastric GIST and complicated with severe acute pancreatitis.
