Psychosocial changes in Medical Students Before and After COVID-19 Social Distancing / 의료커뮤니케이션

Purpose@#: The COVID-19 pandemic has had a far-reaching impact on society. Understanding the changes perceived by medical students is meaningful in that it can suggest the direction of future changes in medical education. The purpose of this study is to investigate the impact of COVID-19 social distancing on psychosocial changes in medical students. @*Methods@#: Anxiety and depression caused by COVID-19, changes in fatigue caused by social distancing, areas where significant changes occurred, and changes in social activity participation and media use behavior among medical students who have experienced the COVID-19 pandemic for more than two years by an online survey. Two hundred twenty-one who are 1st and 2nd-year medical students responded, and we analyzed the results by frequency analysis, independent t-test, paired-sample t-test, and ANOVA. Also, we analyzed Post hoc tests with Tamhane T2, which does not assume equal variance. @*Results@#: The second year of medical school showed higher anxiety and depression than the first. The students who experienced COVID-19 showed lower anxiety, and the more severe the degree of corona blue experience, the higher the anxiety and depression. And the fatigue felt by medical students is higher now than during COVID-19. Areas where the changes due to COVID-19 were seen a lot, were lifestyle attitudes, learning methods, and human relationships. And also, social activities and media medical students use increased after social distancing. @*Conclusion@#: Before and After COVID-19 Social Distancing, medical students have experienced many psychosocial changes.

Sonographic Appearance of Idiopathic Hypertrophy of the First Dorsal Interosseous Muscle of the Hand

We present a rare case of a 28-year-old man with a non-tender soft tissue enlargement on the dorsal side of the first web space of the right hand. Sonographic evaluation showed thickening of the dorsal thenar muscle (dorsal interosseous muscle) without a mass-like or cystic lesion, as compared with the left dorsal thenar muscle. On grasping position, this finding was more prominent and no significantly increased vascular flow was observed in this muscle. We were able to diagnose idiopathic hypertrophy of the first dorsal interosseous muscle solely by sonography. Ultrasonographic evaluation is a noninvasive and accessible tool for diagnosis of pseudotumors, such as idiopathic thenar muscle hypertrophy.

Quantitative Evaluation Using Histo-processing as a Complement of Conventional Hepatic Scintigraphy

The lack of specificity of an abnormal findings visualized on a conventional radiocolloid liver imaging remains a significant limitation of the examination. The purpose of this investigation is to clarify an equivocal abnormal finding visualized on a conventional liver and spleen imaging by using combination of scintiangiography and histogram as a quantiative assessment. Histo-analysis of peak colloidal distribution in the liver and spleen was undertaken as a complement of conventional liver imaging. The following useful patterns was emerged: 1. In hepatitis, the splenic uptake was slightly higher than in normal group. This change was usually not recognized in conventional imaging. 2. In liver cirrhosis, the liver uptake was markedly low whilst splenic uptake was very high, resulting in splenic shift and very low liver-spleen uptake ratio. 3. In hepatoma, the liver uptake was not definitely changed but splenic uptake was considerably high, so that the liver-spleen uptake ratio was very low. 4. In liver metastasis, both liver and splenic uptakes were within normallimits and the liver-spleen uptake ratio was not changed.

Value of lymphography before and after radical hysterectomy in carcinoma of the uterine cervic

Radiological demonstration of lymph vessels and lymph nodes may be achieved only by direct lymphography, whichis perfomred by injecting contrast material directly into the lymph vessels. lymph nodes, or occasionally intolymph cysts. Clinical lymphography is performed essentially according to the direct technique of Kinmonth(1952 &1954). Lymphography has become a routine procedure in patients with carcinoma of the uterine cervix. Thoroughassessment of the extent of carcinoma of the uterine cervix is necessary to the intellignet management of anypatient with uterine carcinoma. This presentation is to outline the technique of lymphangio-adenography(lymphography), lymphographic finding and diagnostic criteria of the cervical carcinoma, and evaluation of theaccuracy of lymphographic diagnosis in cervical carcinoma. A retrospective reivew of the lymphograms of 145patients with carcinoma of the uterine cercix was undertaken. All lymphograms were performed at Kang Nam St.Mary's and St. Mary's Hospitals, Catholic Medical College form 1975 to 1982. Of thse patients 87 were got radicalhysterectomy and lymphographic diagnosis was compared with tissue pathology of the nodes removed, and determinedthe diagnostic accuracy of lymphography. Lymphography can make a significant contribution in the pretreatmentassessment of patients with carcinoma of the uterine cervix. Strict adherence to rigid criteria will yieldexcellent pathologic correlation in the event of a positive radiographic diagnosis of metastatic carcinoma. Once apositive diagnosis is made, it should influence the management of the cancer patients. The results were as follow;1. The accuracy of lymphography in diagnosing lymph node metastasis of carcinoma of the uterine cervix was 85.1%,82.4% in sensitivity and 86.8% in specificity. 2. Metastic lymph nodes were moderately to markedly enlarged andirregular in shape and shown motheaten marginal filling defects in 92.7%. Theses ranged from 3mm to 20mm in thegreatest diameter. 3. Metastatic lymph nodes showed a tendency to get increased in size, inproportion to the sizeof marginal filling defect. 4. The size of filling defect of metastatic lymph nodes was not correlated to theclinical stage of carcinoma of the uterine cervix. 5. Lymph node metastasis was confirmed in 6 patients of 10patients who were got lymphography in 2 to 5 years after radical hysterectomy. 6. Many collateral lymphatics andlymphatic cysts were found out in the lymphography after radical hysterectomy in carcioma of the uterine cerix.
