STUDY DESIGNS: A retrospective study. OBJECTIVES: To analyze the clinical and radiological outcomes of spontaneous reduction via minimally invasive transforaminal lumbar interbody fusion (Mini-TLIF) as the treatment for low-grade symptomatic spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Although minimally invasive transforaminal lumbar interbody fusion is technically demanding, this procedure is an effective method for spontaneous reduction of low grade spondylolisthesis. MATERIALS AND METHODS: We analyzed consecutive series of 41 patients with low grade spondylolisthesis who underwent minimally invasive transforaminal lumbar interbody fusion, between April 2008 and July 2009. The minimum follow-up period was 2 years. Clinical evaluation was performed by an analysis of Visual Analogue Scale and Oswestry Disability Index. For the radiological evaluation, disc space height, slip percentage, and slip angle were analyzed. At the final follow-up, the fusion rate was analyzed according to the Bridwell's anterior fusion grade. RESULTS: For the evaluation of clinical outcomes, the Visual Analogue Scale for back pain decreased from 6.8+/-1.2 to 2.0+/-1.1, and that for radiating pain decreased from 7.9+/-1.3 to 1.7+/-1.1. Oswetry Disability Index decreased from 38.5+/-8.4 to 13.4+/-6.1. For the radiological evaluation, disc space height increased from 8.4+/-2.14mm to 11.8+/-1.54mm(P<0.05), slip percentage was reduced from 18.4+/-5.1% to 13.3+/-3.1%(P<0.05) and slip angle decreased from 10.6+/-4.5degrees to 6.2+/-3.4degrees (P<0.05). At the final follow-up, radiological union was obtained in 38 cases (92.7%). CONCLUSIONS: We conclude that minimally invasive transforaminal lumbar interbody fusion appears to be an effective method for spontaneous reduction of low grade spondylolisthesis if the surgeon becomes familiar with this method.

BACKGROUND: Aprotinin, which is a nonspecific serine protease inhibitor, has an antiinflammatory and thrombogenic effect. However, it has an antithrombogenic effect during the cardiopulmonary bypass. This study was performed to evaluated the effects of aprotinin on the activated clotting time(ACT) and the total amount of the heparin used during the cardiopulmonary bypass. MATERIAL AND METHOD: From December 1998 to November 1999, 82 consecutive patients electively underwent open heart surgery at Gachon medical school. The patients were older than 18 years. Eighty two patients were classified into a control group(group C, n=36) and a aprotinin-treated group(group A, n=46). Body weight, height, body surface area(BSA), pump time(PT), aortic cross clamping time(ACCT), and body temperature(BT) were determined. Total amount of heparin and protamine during the CPB were also measured. ACT was determined before heparin administration, at 20, 40 and 60 minutes after heparin administration, and after protamine administration. RESULT: No significant differences were noted in either group in body weight, height, BSA, BT, and the total amoun of heparin and protamine. Group A demonstrated a significant(p<0.05) increase in age, PT, ACCT, and ACT at 20, 40, and 60 minutes after heparin administration. CONCLUSION: In summary, the use of aprotinin prime resulted in an increase in ACT. The total amount of heparin in aproinin-treated patient was similar to that of the control group in spite of having the prolonged pump time. Therefore aprotinin may reduce the requirement of heparin.

PURPOSE: The pharmacologic effect of atropine on HPS can be considered to control pyloric muscle spasm. Therefore, we studied the effects of intravenous atropine sulfate on the clinical course of HPS, and periodically observed the ultrasonographic appearance of the pyloric muscles after atropine treatment. METHODS:From April 1998 to May 1999, 14 infants who were diagnosed with HPS were treated with intravenous atropine sulfate. Intravenous atropine sulfate was administered at an initial dose of 0.04mg/kg/day, which was divided into 8 equal doses. The daily dose was increased by 0.01 mg/kg/day until vomiting was controlled for an entire day while infants received unrestricted oral feeding. Ultrasonographic examinations were performed during hospitalization and repeated at least every 2 months until normalization of pyloric muscles was confirmed. RESULTS: Intravenous atropine was effective in 12 of 14 infants with HPS and the conditions of 9 of them improved. Two infants who were not free from vomiting despite a week of intravenous atropine sulfate treatment underwent pyloromyotomy. A series of ultrasonographic examinations were done after vomiting had improved with intravenous atropine sulfate. The ultrasonographic findings showed good passage of gastric contents through pyloric canals despite thickening of the pyloric muscles. CONCLUSION: Intravenous administration of atropine sulfate is an effective therapy for HPS and can be an alternative to pyloromyotomy. (J Korean Pediatr Soc 2000;43:763-768)

A histopathologic observation was made on 24 patients with cryptorchism admitted to the Department of Urology, Seoul Adventist Hospital during the periods from November 1981 to April 1983. The following results were obtained. 1. The age distribution was ranged from 2 to 28 years and 6 to 10 years of age group was the most commonly affected (9 cases, 37.5%). 2. The most common type of cryptorchidism was the inguinal type (14 cases, 58.3%). The bilateral cryptorchismswere observed in 6 cases and unilateral 18 cases, among them right in 12 cases, left in 6 Cases. 3. On the histopathologic findings of testicular biopsy in 24 cryptorchid testes; per{tubular fibrosis which began before puberty was noted the earliest finding and basement membrane of seminiferous tubules were significantly thickening during puberty. Leydig cells were increased during puberty and they became normal level after puberty but spermatogenesis were not completely observed through all the age group.
