Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

Real-time ultrasongraphy is a simple, accurate, noninvasive and potentially valuable means of studying gallbladder size and emptying. The authors calculated ultrasonographically the ejection fraction of 80 cases of normally functioning gallbladder on oral cholecystography, from June 1983 to April 1984, at the department of radiology, Hangang Sacred Heart Hospital. The results were obtained as follows; 1. Ultrasongraphic Ejection Fraction at 30 minutes after the fatty meal was 73.1+-16.85. 2. There was no significant difference in age and sex, statistically.

The muscle glycogen is an important energy source for muscle contraction especially in prolonged exercise. One of the important factors for improvement of physical performance in athletes is the storage of extra-amount of glycogen (supercompensation) in liver and muscles. During 120 minutes treadmill exercise (intensity of exercise was approximatly 80% VO2max), the glycogen concentration was significantly decreased to 36% in liver and 46% in muscles after 60 minutes exercise. At 90 and 120 minutes of exercise, the level of glycogen concentration of liver and muscles statistically were not different from the levels of the 60 minutes exercise. The repletions of glycogen in the liver and muscles in overnight fasted control(C) and 120 minutes treadmill exercise(E) groups during l80minutes after glucose ingestion were investigatect. ln the liver, the concentration of glycogen in C and E groups were markdly increased till 120 minutes after zlucose ingestion, hut the levels of concentration at 180 minutes were decreased comparing to the levels of 120 minutes in both groups. In the muscles, the repletion of glycogen at 60, 120 and 180 minutes of C and E groups were significantly increased comparing to 0 minute of respective groups in the soleus and plantaris muscles. In soleus(SOL), the repletion of glycogen in all of the E groups was significantly higher than that of the respective C groups. However, the repletion of glycogen in all of the E groups of plantaris was revealed higher tendency comparing to respective C groups. Mean repletion rates of glycogen in liver and muscles after glucose ingestion were highest during the first 60 minutes in all groups and the rates of E groups were 2-3 times than those of respective C groups. These results suggest that the glycogen supercompensation in the muscle be provided with decrement of glycogen concentration by exercise, increment of glucose uptake by muscuiar contraction itself and increased insuJin level, and the activation of glycogen synthetase by insulin.

Due to the instability of intertrochanteric fractures in elderly patients, various methods of reduction and fixation were introduced to obtain stable reduction and solid union, But there have been many controversies regarding advantages between anatomical reduction group and non-anatomical reduction group. The authors analyzed the 68 unstable intertrochanteric fractures out of total 94 cases of intertrochanteric fractures treated from Jan. 1988 to Jan. 1994 with mean follow-up 17 months and evaluated the radiologic and clinical results between those two groups. The results were obtained as follows: 1. The most common cause was low energy injury and according to the Tronzo classification, the type III was most common in 54 cases (79.4%). 2. The average union time was 14.0wks (84%), the union rate was low in the medialized reduction group(A-P) and anterior displaced reduction group(A-P), anterior displaced and anatomical reduction groups(Lateral). 3. The compression length more than 10mm of lag screw was deep in medialized reduction group(A-P), another displaced and anatomical reduction groups(Lateral). 4. The average length of lag screw sliding was 9.2mm and depth sliding of 6.8mm (74%) was occurred within immediate postoperative 1 month.

Fractures involving both tibial plataeus result form high energy trauma such as a traffic accidents or falls, and it is frequently accompanied by soft tissue injuries. Thus it is very difficult to treat these fractures satisfactorily and severe complications can be caused. The purpose of study is to analyze the clinical results, complication and factors influencing the results after open reduction and internal fixation of tibial bicondylar fractures. Twenty cases(19 patients) of tibial bicondylar fractures which had been treated by open reduction and internal fixation from January 1989 to December 1994 were analyzed after 1 to 5 years follow-up. The results were as follows. 1. By AO classification, the most common type was C3(13 cases). 2. According to Blokker's criteria, 5 cases was unsatisfactory and all of these cases were C3. 3. Unsatisfactory results were 3 cases of reduction loss(angular deformity), one case of deep infection and one case of unresolved peroneal nerve palsy. 4. Tibial tubercle osteotomy, bone graft and medial buttress plate were important for anatomical reduction and maintenance.

7.The effects of COVID-19 on physician’s burnout: a systematic review
Journal of the Korean Medical Association 2021;64(9):636-646
Background:
To suggest measures to prevent burnout of physicians during the coronavirus disease 2019 (COVID-19) pandemic, we conducted a systematic review of research on physician burnout due to COVID-19.
Methods:
Three foreign databases were used: MEDLINE, Embase, and the Cochrane Library. A search was performed using the following search terms: COVID-19, coronavirus, NCOV, physicians, doctors, residents, and burnout. Four rounds of review were performed to enhance the consistency of quality assessment. The Joanna Briggs Institute checklist for analytical cross-sectional studies was used to assess the quality of the eligible studies.
Results:
A total of 465 studies were identified, of which 32 were selected. The quality assessment determined that 19 studies met the Joanna Briggs Institute criteria and had a low risk of bias. The most common tool used to measure physician burnout in the 32 studies was the Maslach Burnout Inventory.
Conclusion
This study systematically evaluated the literature on physician burnout. However, the generalizability of our findings to Korean physicians may be limited. The composition of the medical personnel in Korea, such as open doctors, volunteer doctors, medical professors, and public health doctors, differs significantly from that of other countries. Nevertheless, evaluating the current status of physician burnout due to COVID-19 globally may hold meaningful implications for policymaking.

BACKGROUND AND OBJECTIVES: Although a prominent large V wave in left atrial pressure tracing (PVLAP) has been reported to be associated with significant mitral regurgitation (MR) or decreased left atrial compliance (LAC), it is sometimes observed in patients with tight mitral stenosis (MS). The purpose of this study was to determine the prevalence and the hemodynamic significance of PVLAP in tight MS. MATERIALS AND METHODS: Catheterization data before percutaneous mitral balloon valvuloplasty (PMV) were analyzed in 84 consecutive patients and PVLAP was defined as V wave 10 mm Hg higher than mean left atrial pressure (MLAP). RESULTS: PVLAP was observed in 45% (38/84) and factors associated with PVLAP were younger age (p=0.02), higher MLAP (p<0.01), higher mitral gradient (p=0.04), smaller valve area (p=0.01) and low echo score (p=0.02): among them MLAP was the only independent factor in multivariate analysis. The presence of PVLAP had no effect on the result of PMV and successful PMV abolished PVLAP. CONCLUSION: PVLAP was observed not infrequently in these selected patients with MS referred for PMV. The presence of PVLAP was not associated with MR and had good correlation with MLAP, which suggest that PVLAP be determined by decreased LAC.
