0.05). 2. At the total success rate, osteotome group was 92.4% and Hatch reamer group was 94.9%. There was no statistically significant difference between the two groups (P > 0.05). 3. On the discomfort during the operation by using numerical rating scale, osteotome group was 2.87 +/- 0.83 and Hatch reamer group was 1.12 +/- 0.64. There was statistically significant difference between the two groups (P < 0.05). The Hatch reamer group' clinical results was similar to osteotome group and we thought that Hatch reamer technique can overcome the faults of osteotome technique.]]>

Since the first report on infective endocarditis by Rokitansky in 1985, this subject has been extensively dealt with in the world literature. Nowadays by use of echocardiography, there has been a high discovery rate of vegetation, and thus made it a valuable tool in diagnosis, treatment, and the evaluation of the patient. However in Korea, there have been only a few case reports and even fewer studies on infective endocarditis. This study is a clinical analysis of 87 infective endocarditis cases, which were admitted and treated at the department of Pediatrics and Internal medicine, diagnosed as infective endocarditis, during the period from january 1975 through February 1984. 1) The mean age was 24.8 years and male to female ratio was 1.49:1. 2) Annual incidence showed no increment during the period and it was 1:2500. 3) Underlying heart diseases consisted of rheumatic heart disease(52.3%), congenital heart disease(39.7%), no underlying heart disease(8%), previous infective endocarditis(4.6%), and prosthetic valve endocarditis(3.4%). 4) Frequent clinical manifestations on admission were high fever, heart murmur, congestive heart failure and frequent laboratory findings were positive blood culture results, anemia, positive C-reactive protein, and hematuria. 5) Blood culture was positive in 75.9% and the most common infecting organism was alpha-streptococcus, which represented 42.4% of total positive cases. S. aureus and S. epidermidis were next common and these three organisms consisted of 71.2% Culture positivity was not significantly related to the type and incidence of complications. 6) Antibiotics sensitivity of the major isolated organisms were performed. Alpha-streptococcus was sensitive to almost all antibiotics except Tetracycline. Group D-streptococcus was sensitive to Chloramphenicol and Cephalosporin. S. aureus and S. epidermidis showed same results, which showd sensitivity to Chloramphenicol, Cephalosporin and Methicillin and resistence to penicillin. 7) Echocardiography was performed in 55 cases and showed vegetation in 58.2%. Complications related to the echocardiographic identification of the vegetations showed difference only in the mortality rate, which was greater by 3 times in the positive cases than in the negative. 8) Peripheral embolizations occurred in 29.9% of cases, and by far the mostcommon site was the brain, where 63% of the embolism was localized. 9) Sufficient duration of hospitalization(4-6 weeks) and judicious antibiotics administration was done in 43.7%. The initial response to therapy was noted in 48.5% of total febrile cases. 10) The mortality rate of the cases was 13.8% of the patients died. However, as many patients were discharged against advice because of socio-economic factors, precise therapeutic results of these cases could not be obtained.

Gastric volvulus is characterized by an abnormal rotation of the stomach typically 180degrees left to right around a line joining the relatively fixed pylorus and the esophagus. Gastric volvulus can be classified anatomically as organoaxial, mesenteroaxial or combined, and symptomatically as acute or chronic. Acute gastric volvulus is an extremely rare emergency surgical condition. The classical triad of gastric volvulus are severe nausea with a paradoxical inability to vomit, localized epigastric pain and an inability to pass a nasogastric tube. Gastric volvulus may be suspected on a plain radiological examination of the abdomen as well as by its symptoms. It is confirmed by the specific findings on the esophagogastroduodenoscopy. We report a case of acute mesenteroaxial gastric volvulus, that was treated using laparoscopic reduction and anterior gastropexy.

BACKGROUND: These days, lung volume reduction surgery (LVRS) is used as an alternative or a bridge operation to lung transplantation in treating patients with severe emphysema. The procedure can be used in patients with pulmonary nodules combined with severe emphysema. We report the results of 21 months follow up after lung volume reduction surgery in 7 cases including 2 cases of concurrent resection of pulmonary nodules. MATERIAL AND METHOD: Seven patients with emphysema, including 2 cases of preoperatively suspected lung cancer were operated with LVRS technique between July 1996 and June 1997. RESULT: Postoperative mortality was observed in a case of squamous cell carcinoma in LUL with brain metastasis, detected at postoperative 13months. Average of 21months(19-25months) follow up was done for other cases without specific events. CONCLUSION: LVRS is a useful operation in the treatment of patients with severe emphysema, but further evaluation should be done about the long term results and precise criteria for patient selection. Simultaneous LVRS and tumor resection could be done in patients with emphysema with marginal reserve in the hope of maximizing postoperative lung functions.

PURPOSE: To determine the effect of photodynamic therapy (PDT) on patients with chronic central serous chorioretinopahty (CSC). METHODS: This was a retrospective multicenter study. We collected demographic and ophthalmic data for patients with chronic CSC who were treated with PDT from 16 institutions in Korea. The best corrected visual acuity (BCVA), ophthalmoscopic finding and optical coherence tomography at baseline and follow-up visits were compared longitudinally. RESULTS: Sixty-five eyes of 65 patients were recruited. Males (51 patients, 78.5%) outnumbered females (14 patients, 21.5%). The mean age was 46.4+/-10.0 years of age (28~69). By 1 month, mean BCVA improved from 0.47 to 0.37 (logarithm of the minimum angle of resolution) (P <0.01). This BCVA increased throughout 6 months. Subretinal fluid resolved partially or completely in 89.1% of the patients. Central macular thickness (CMT) decreased from 303.4 to 168.7 micrometer. The amount of change in CMT after PDT was correlated to the female sex and prePDT CMT. At 3 months after PDT, the amount of change in BCVA was significantly related to that of change of CMT (p <0.05). Adverse events were reported in 4 cases, however, most were mild. CONCLUSIONS: PDT was effective and safe for treating chronic CSC.

Background: and Purpose Epidemiologic data suggest that cluster headache (CH) is significantly associated with cigarette smoking. The aim of this study was to determine differences in features between patients with a smoking history and those who are never-smokers, using data from a prospective multicenter registry. Methods: Data used in this study were obtained from the Korean Cluster Headache Registry that collected data from consecutive patients diagnosed with CH. We compared clinical and demographic features between ever-smokers (current or former smokers) and never-smokers. Results: This study enrolled 250 patients who were diagnosed with CH, of which 152 (60.8%) were ever-smokers and 98 (39.2%) were never-smokers. The age at CH onset was significantly lower in the never-smoker group than in the ever-smoker group [27.1±12.9 years vs. 30.6± 10.9 years (mean±standard deviation), p=0.024]. Seasonal rhythmicity (58.1% vs. 44.7%, p= 0.038) and triptan responsiveness (100% vs. 85.1%, p=0.001) were higher in never-smokers, while other clinical features such as pain severity, duration, attack frequency, and associated autonomic symptoms did not differ significantly between the groups. The male-to-female ratio was markedly higher in ever-smokers (29.4:1) than in never-smokers (1.7:1). Conclusions Most of the clinical features did not differ significantly between patients with a smoking history and never-smokers. However, the age at CH onset, sex ratio, and seasonal rhythmicity were significantly associated with smoking history.
