1.A Case of Pacemaker-mediated Tachycardia.
Journal of the Korean Society of Emergency Medicine 1999;10(4):686-692
Pacemaker-mediated tachycardia(PMT) is a circus movement tachycardia that can occur in patients with dual chamber pacemaker with atrial sensing(VDD or DDD), when a ventricular depolarization, either spontaneous or paced, causes retrograde activation of the atrium. Recently, a number of pacemaker manufactures have incorporated in their devices a variety of relatively complex algorithms to prevent PMT. Despite these measures, PMT may still occur because of inappropriate programming or unpredictable variations of ventriculoatrial conduction. We report one case of PMT in a 78-year-old male who received DDD type pacemaker due to sick sinus syndrome. In this case, PMT was disappeared after reprogramming parameters of pacemaker and the application of PMT protection algorithm.

Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.

There are many controversies in ability of articular cartilage to heal full thickness defect. Generally, it is reported that full thickness defects of articular cartilage filled with organizing hematoma and granulation tissues, which converted to chondroid tissues. It is clear that the size of defect was related to the repair of articular cartilage. Though cartilagenous material fills the defect and restores the surface continuity, it may undergo degeneration, and lead to localized focus of osteoarthritis. Multiple drilling through subchondral bone could be a kind of treatment in articular cartilage defect. Author conducted an experiment for the full thickness defect of articular cartilage in rabbit. After multiple drilling of articular cartilage, the repair of defect was examined histologically until eighth week. Results were as followings ; l. At lst. week, the defect was repaired by fibrovascular proliferation and granulation tissue. 2. At 3rd. week, hyaline cartilage consisted of normal chondrocyte was formed. 3. At 8th. week, subchondral plste was regenerated completely. 4. All defects that were less than 3 mm. in diameter were healed. More repairs were observed in case with the wider defects if the defects were within 3mm. in diameter. 5. The metachromasia was observed with toluidine blue stain. The reformed cartilage shows slight purple(Grade II) to moderate purple(Grade III) at third week and near normal (Grade IV) at fourth week. In conclusion, multiple drilling may be an effective method of treatment in articular cartilage defect. It is considered that multiple drilling with a 3mm. Steinmann pin may be the most convenient and effective method of the cartilage healing.

The aim of this study was to evaluate the appropriateness of some kinds of surgery and admission, such as cesarean section (C/S), cholecystectomy, and pediatric pneumonia. For appropriateness evaluation, we ourselves developed some criteria, which were included in the category of explicit and linear criteria, with the assistance of specialists of relevant clinical field. The evaluation of appropriateness was performed by two family physicians. The major findings were as follows: 1. For ceserean section, 77.6% of deliveries were determined to be 'appropriate', but the level of appropriateness was not significantly different among hospitals between hospital groups by size. The most frequent indication of C/S was repeated operation, followed by cephalopelvic disproportion(CPD). The labor trials for vaginal delivery among repeated C/S and CPD cases were performed in 24.5% of pertinent deliveries. 2. About 73.8% of cholecystectomy cases was appropriate to one of the surgical indications, without significant differences among hospitals. Of surgical indications, 'sufficiently frequent and intense symptom recurrence' was the most frequent, and 'confirmed acute cholecystitis' was the second. 3. Of children admitted due to pneumonia, only 57.4% of cases satisfied admission criteria, and the level of appropriateness of admission was different among hospitals. The common reasons for admission were 'failure to initial treatment', 'suspected bacterial pnermonia', 'young infant', etc. We could find that there were differences of quality among hospitals in some procedures, especially in the pediatric pneumonia and labor trial before C/S, which suggested that the implementation of quality assurance activities would be necessary in this country. In this study, we used some simple and primitive research tools and the numbers of subjects and tracer procedures were limited. So advanced studies with plentiful subjects and more representative diseases or procedures should be tried.
