OBJECTIVES: Health care workers(HCWs) are more likely to become infected with tuberculosis from patients in the hospital. When HCWs have an active tuberculosis infection, it is possible that they also become a source of infections to other HCWs and patients. METHODS: Tuberculin tests were performed with mantoux method using 5 units of tuberculin by infection control practitioners on Feb. 21, and Mar. 7, 1997. A total of 138 newly employed HCWs including 44interns and 94 nurses were tested. Results of skin test were interpreted by themselves according to the instructions. RESULTS: Among 138 personels, skin tests were negative in 27 personels (19.6%); 4 interns (9.1%) and 23 nurses (24.5%). There were 3 persons (2.2%) who had a history of tuberculosis which had been treated. CONCLUSION: The study showed that approximately 20% of newly employed HCWs had negative tuberculin skin test. Given the possibility of being infected with tuberculosis in the hospital, regular follow up of tuberculin skin test is warranted to protect HCWs,

Stratum corneum was obtained from 10 healthy individuals aged 23 and 24 years, in order to observe morphological differences in a three-dimensionsl structure of stratum corneum from 3 anatomical sites, i. e., flexor surface of the forearm, abdomen, and palm. The stratum corneum obtained by the skin surface biopsy was ohserved under a scanning electron microscope(SME). The surfaces of stratum eorneum obtained by the replice, technique were observed under a stereomicrascope(SM). The results were as follows : 1) SEM observation of the posterior surfaces of the stratum corneum from the skin surface biopsies of the flexor surface of the forearm and abdomen showed divisions with folding lines which were elliptic in the forearm and squere in the abdomen. But there were no similar folding linea in the palm. Among the 3 anatomiral sites, overlapping corneocytes on the palm were most prominent. On a higher magnification, small pits and fine wrinklings in the forearm, fine wrinklings in the abdomen, and villous projections in the palm were observed respeeti vely. 2) SM observation of the stratum corneum from the negative replica of the flexor surface of the forearm, abdomen, and palm showed divisions with folding lines which were X-shape a.t the site of their crossinga in the forearm, *-shape in the abdomen, and linear shape in the palm, Among the 3 snatomical sites, tiny holes on the palm were most prominent. Follicular openings were observed on the pa1m, and abdomen,

Insulinoma is the most frequent endocrine tumor of the pancreas and the first of the endocrine-secreting tumor of the gut to be recognized by Nicholls in 1902. Recurrent episodes of hypoglycemia is the main cause of the symptoms and signs which were sweating, pallor, dizziness, habitual change, convulsion and coma. In 1935, Whipple and Frants were described so-called “Whipple's triad”: the patient's symptoms occur with fasting or exercise; at the time of symptoms, the serum glucose in 50mg/dl or less; and the symptoms are relieved by the administration of glucose. While these criteria were timely, they proved to be rather nonspecific and may be found in other conditions that result in fasting hypoglycemia. We experienced a 44-year-old female patient who had repeated attacks of convulsion, unconsciousness and coma for 3 years. Although she has been treated with anticonvulsant, the symptoms and signs were not disappeared. At the time of administration, she was a full coma state due to hypoglycemia and was dramatically reversed by intravenous administration of the glucose solution. The preoperative test such as provocative test, abdominal CT and celiac angiography revealed insulinoma and after enucleation the pathologic diagnosis was the same. We like to report an adult female patient with insulinoma and the review of literatures briefly.

An experimental study on the effect of the induced dislocation of the femoral head on the femoral anteversion was made in the hips of 55 rabbits, three to four weeks old. The results were as follows; l. In 49 of the 55 operated rabbits, a relative increase of anteversion was observed on the dislocated side, as compared with the nonoperated femur, the differences ranging from 3 to 55 degrees with an average of 20.0 degrees. 2. The anteversion angle of dislocated hip showed steady and gradual increase with the increase of age. 3. The anteversion increase was detected very early after operation; 3 of the 4 rabbits, belonging 4 to 7 days group after operation showed the anteversion increase. 4. The collapse of proximal femoral epiphysis was observed in 42 of the total 55 hips. The incidence of the collapse was higher in postoperative 4 weeks and more groups. 5. The color change, pale discoloration, of the articular cartilage was observed in 32 of the total 55 hips. The icnidence of pale discoloration was higher in the groups within 8 weeks after operation.

Objective: Mechanical thrombectomy (MT) is an effective treatment for patients suffering from acute ischemic stroke secondary to large vessel occlusion. However, recanalization failure rates of interventions were about 20% in literature studies. We report our experience of unsuccessful MT with a focus on technical reasons. Methods: From December 2010 to June 2021, six hundred eight patients with acute ischemic stroke due to large artery occlusion received MT using a stent retriever with or without an aspiration catheter in our institution. We divided the reasons for failure into six categories. We analyzed the reasons for failure by dividing our experience time into 3 periods. Results: A total of 608 cases of thrombectomy for large vessel occlusion were identified in the study period. The successful recanalization rate was 90.4%. In most of the cases (20/57, 35%), the thrombus persisted despite several passes, and the second most common cause was termination of the procedure even after partial recanalization (10/57, 18%). Similar proportions of in-stent occlusion, distal embolization, and termination due to vessel rupture were observed. On analysis of three periods, the successful recanalization rate improved over time. Conclusions MT fails due to various reasons, and intracranial artery stenosis is the main cause of MT failure. With the development of rescue techniques, the failure rate has gradually decreased. Further development of new devices and techniques could improve the recanalization rates.

We report a case of cutaneous calcinosis following extravasation of calcium calcium chloride in a 3-week old neonate, After extravasation of 3% calcium chloride infusion, rapid and marked swelling, erythema, and signs of soft tissue necrosis developed over the extensor surface of both upper extremities. Through the small channels of the destroyed epidermis, tiny white pieces of calcific masses were eliminated spontaneously. Histologically the calcium deposits were found as amorphous masses in the upper dermis and the discharge of calcium deposits also took place by means of transepidermal elimination. The central bone formation and surrounding calcium deposition were present along with dense lymphohistiocytic cell infiltration in the deep dermis. Complications of extravasation of calcium solution during intravenous infusion included localized calcification and, ocasionally necrosis. The incidence of compllcations was about eight percent. This is a case which again emphasises of the danger of using calcium chloride intravenously in the neonate or young infant.

PURPOSE: To evaluate the therapeutic efficacy of intravitreal bevacizumab (IVB) in the treatment of branch retinal vein occlusion (BRVO) in eyes with normal tension glaucoma (NTG). METHODS: We included 16 NTG eyes and 48 age- and sex-matched eyes without NTG that had received IVB for BRVO with more than 6 months of follow-up. The main outcome measures were log MAR best-corrected visual acuity (BCVA) and central macular thickness (CMT) at baseline and 1, 3, and 6 months after IVB. We compared the results according to the comorbidity associated with NTG. RESULTS: The obstruction site of BRVO was significantly closer to the optic disc in eyes with NTG than in eyes without NTG. Baseline log MAR BCVA and CMT were similar between the two groups. After IVB, postoperative BCVA was significantly improved and CMT was significantly reduced, irrespective of the comorbidity associated with NTG. However, vision improvement was more limited in eyes with NTG, while CMT was similarly reduced compared with that in eyes without NTG. The mean numbers of injections were similar between the two groups, and there were no injection-related complications. CONCLUSIONS: IVB may have therapeutic efficacy in the treatment of BRVO associated with NTG. However, the comorbidity associated with NTG may limit vision improvement, although anatomic recovery of CMT is achieved.
