This study examined factors related to high fear of coronavirus disease 2019 (COVID-19) infection in healthcare workers (HCWs) in COVID-19 dedicated teams. We assigned 371 HCWs to low, medium, and high COVID-19 infection fear groups, and investigated factors associated with COVID-19 infection fear. High COVID-19 infection fear was significantly associated with being a woman and poor professional quality of life. High COVID-19 infection fear group had higher burnout levels and secondary traumatic stress scores than the low and medium fear groups. These findings deepen our understanding of risk factors for and psychological outcomes of COVID-19 infection fear in HCWs.

A case of Fetus-in-fetu is reported. The patient was a 8 month-old-boy with a tumor in the left upper retroperitoneum. The characteristic feature of the specimen consisted of vertebral column including pelvis, both upper and lower extremities, neural canal and brain tissue, and well formed large intestine.

PURPOSE: The purpose of this study was to evaluate and compare the scintigraphic findings and diagnostic accuracy of double-phase Tc-99m sestamibi scan in primary and secondary hyperparathyroidism (HPT). MATERIALS AND METHODS: We retrospectively reviewed 16 cases of primary (18 lesions) and 11 cases of secondary HPT (44 lesions) who underwent Tc-99m-sestamibi scan before the surgical intervention. Scan was performed using LEM camera (Siemens, Germany) after the injection of 740MBq of Tc-99m sestamibi. Routine image consisted of baseline and 3-hour delayed images and each image was obtained using both parallel and pine hole collimator. The study population was 27 patients (male/female=5/22, age: 49.1+/-10.8). RESULTS: Eighteen lesions of primary HPT consisted of 13 adenomas and 5 hyperplasias, while all lesions of secondary HPT were hyperplasias. Among the case of primary HPT, we could detect all the lesions of 13 adenomas but only 2 lesions of 5 hyperplasias (40%) could be detected by double phase scintigraphy. Three cases of primary lesion showed decreased uptake in delayed images compared with baseline. The sensitivity, specificity, positive predictive value and accuracy of primary and secondary HPT were 58.8% (10/17), 83.3% (10/12), 83.3% (10/12), 75.9% (22/29), and 37.5% (15/40), 50% (2/4), 88.2% (15/17), 38.6% (17/44), respectively. Overall sensitivity, specificity, positive predictive value and accuracy were 43.9% (25/57), 75% (12/16), 86.2% (25/29), and 53.4% (39/73). There were no statistical difference between the weight of primary and secondary HPT lesion (p>0.05). CONCLUSION: Tc-99m sestamibi scan is fairly good modality to detect parathyroid lesion in patient with primary HPT before the surgical intervention. However, since some of cases may reveal decreased uptake in delayed image, a careful attention to the findings of baseline images may be helpful. Still the low accuracy of sestamibi scan in diagnosis of secondary HPT prohibits routine use of it for this disease.

Abnormalities in the number and function of platelets may contribute to thromboembolic complications in patients with essential thrombocythemia(ET). Physicians often use hydroxyurea which reduces the platelet count for the initial treatment of ET. A 74-year-old man with ET was presented with headache, dysarthria, and right hemiparesis 10 months after discontinuation of hydroxyurea. Initial platelet count was 450x103/microliter and we gave him heparin. However, his platelet count rised upto 1,019x103/microliter within 4 days. He was on hydroxyurea 1.5 g/day and his symptoms improved with decrease of platelet count. We report a case of left MCA(middle cerebral artery) multifocal infarction in ET after discontinuation of hydroxyurea.

Screening test of Human Immunodeficiency Virus(HIV) infection was introduced on Korean Blood Donor Test Program in July 1987, and the test results between July 1987 and December 1990 were reported on the Korean Journal of Blood Transfusion on May 1992. Moreover, we assessed anti-HIV ELISA screening test result of 3,905,986 blood donors donated at Korean Red Cross Blood Centers between January 1991 and December 1993. The seropositivity of anti-HIV ELISA screening test was 0.26% in 1991, 0.30% in 1992 and 0.18% in 1993.0.15% of all donors in 1991 was reactive repeatedly, and 0.15% in 1992 and 0.08% in 1993. The prevalence of HIV infected donors confirmed by Western Blot Assay was 0.0003% in 1991, 0.0015% in 1992, and 0.0009% in 1993. The sero-positivities of anti-HIV screening tests with AIDSDIA reagent and HIVIRO reagent were 0.32% and 0.17% and the difference was significantly(p<0.05). The sero-positivities of ELISA screening and Western Blot. Assay detecting anti-HIV were lower in soldier group than in non-soldier donor group (p< 0.05).
