In these days, there are two main ways in the treatment of the avascular necrosis of the femoral head in adult by prosthetic replscement; total hip replacement and bipolar endoprosthesis. So far, no study has been performed on the post-operative functional evaluation of them. Therefore it is difficult to decide which one is preferred to the other in the treatment of avascular necrosis of the femoral head in adult. In order to evaluate the functions of the prosthetic joints, the authors reviewed the results of 18 cases of cementless bipolar endoprosthesis(abbreviated as CBE) and 22 csses of cementless total hip replscement arthroplasty(abbreviated as CTHRA), performed at the Department of Orthopedic Surgery, Seoul National University Hospital, during the period from February, 1984 to May, 1986. The following results were obtained. 1. The average ages of CBE and CTHRA groups at the time of operation were 48.5 years and 37.5 years, respectively. 2. The average follow-ups of CBE and CTHRA were 15.7 months and 30.5 months, respectively. 3. By Meyer's modification of Marcus and Enneking classification, the sverage stages of CBE and CTHRA groups were 3.7 and 4.4 respectively. 4. According to Harris hip rating score system, Harris scores were increased as much as 30.5 in CBE group and 30.6 in CTHRA group. 5. In the aspects of functional improvement and relief of pain, the two groups showed no significant difference. However, the operation was essier, and the damage to the acetabular bone was less in CBE group. For these reasons, CBE was believed to be the preferred choice of treatment of avascular necrosis of femoral head in adult.

Cyclic Neutropenia is a benign, unusual hematologic disorder characterized by regularly recurring episodes of severe neutropenia occurring approximately every 21 days. Beside neutrophils, monocytes, lymphocytes, platelets and reticulocytes all cycle with strict periodicity suggest that this disease should be viewed as cyclic hematopoiesis, not merely as cyclic neutropenia. During neutropenic periods, patients regularly experience aphthous stomatitis, fever, malaise, cervical lymphadenitis, cutaneous infections and occasional pneumonia and otitis media. The exact cause of cyclic neutropenia is unknown. But it is strongly suggested that cyclic neurtopenia is due to an abnormality in the regulation of early hematopoietic precursor cells. We have documented a case of cyclic neutropenia for a period of 2.5 years in a 11 year-old boy who had suffered from recurrent fever, stomatitis, gingival swelling, cervical lymphadenitis and skin infections at 3 weeks intervals since 5 years of age. A brief review of the related literatures is presented.

PURPOSE: Extracorporeal shock wave lithotripsy(SWL) is currently prorposed for the first line treatment of most renal and ureteral stones. In general, SWL is very effective and non-invasive method than open surgery or endoscopic lithotripsy. We experienced 350 cases of SWL for 46 months and announced it. MATERIALS AND METHODS: We retrospectively reviewed the data of 324 patients(350 stones) who had been diagnosed as renal or ureteral stones and underwent SWL using Tripter Compact(R) lithotriptor from September 1994 to July 1998. Male to female ratio was 1.9:1 and patient`s ages ranged from 18 to 82 years(mean 43.7 years). We underwent SWL only with parenteral analgesics for pain control. RESULTS: In 350 stones, renal stones were 90 cases(25.7%) and ureteral stones were 260 cases(74.3%). In 90 renal stones, calyceal stones(include 1 staghorn stone) were 62 cases(68.9%) and renal pelvic stones were 28 cases(31.1%). In 260 ureteral stones, upper ureteral stones were 209 cases(80.4%), mid ureteral stones were 10 cases(3.8%), and lower ureteral stones were 41 cases(15.8%). The stones from 10 to 19mm in diameter were the majority of renal stones(53.3%), whereas in ureter, the stones smaller than 10mm in diameter were most common(41.5%). Less than 3 treatment sessions were needed for 147 cases(93.0%) of stones smaller than 10mm and for 146cases(76.0%) stones larger than 10mm. Less than 3 sessions were needed for 68 cases(75.6%) of renal stones and for 225 cases(86.5%) of ureteral stones. All renal stones were fragmented and the success rate for upper ureteral stones was 93.3%(195/209), for mid ureteral stones was 80.0%(8/10), and for lower ureteral stones was 80.5%(33/41). According to the size of stone, the success rate for the stones smaller than 10mm in diameter was 96.2%(152/158) and for the stones larger than 10mm was 90.6%(174/192). Total success rate was 93.1%(326/350). The complications after SWL were gross hematuria over 24hours(64 cases, 18.3%), flank pain(52 cases, 14.9%), gastrointestinal disturbances(7 cases, 2%), and Steinstrasse(31 cases, 8.9%). The causes of failure were incomplete fragmentation(21 cases, 87.5%) and mucosal impact(3 cases, 12.5%) of stones. Re-treatment rate was 59.7% and auxiliary procedure rate was 8.0%(efficiency quotient was 0.56). CONCLUSIONS: Our experiences shows extracorporeal shock wave lithotripsy is a safe and effective method for the treatment of renal and ureteral stones, and we expect the better outcome by development of techniques and equipments.

PURPOSE: To compare the effect of medial rectus recession in consecutive esotropes who had previous monocular medial rectus resection and lateral rectus recession and in non- accommodative esotropes (NAET) with small angle of deviation who had no prior operation. METHODS: We studied the results of unilateral medial rectus recession at postoperative 2 and 6 months in 7 consecutive esotropes and 19 NAET with deviation angle around 20 PD, and analyzed the corrected amount for 1 mm medial rectus recession. We regarded deviated angle of+/-8 PD at orthophoria as successful operation. RESULTS: The abosolute value of remained deviation in consecutive esotropes and NAET were 4.86+/-5.67 PD and 9.05+/-3.95 PD at postoperative 2 months, and 5.42+/-7.89 PD and 8.26+/-4.45 PD at postoperative 6 months, respectively. There were significant differences between at postoperative 2 and 6 months (p<0.05). The success rates in consecutive esotropes and NAET at postoperative 2 months were 86% and 42%, and 71% and 47%, respectively at postoperative 6 months, which were no significant differences (p>0.05). The average amount of corrected deviation for 1 mm recession at postoperative 6 months was 5.84 PD in consecutive esotropes and 2.97 PD in NAET, which were significant differences (p<0.05). CONCLUSION: Unilateral medial rectus recession in consecutive esotropes may be a useful and first choice of operation procedure when considering second operation. The amount of correction for 1 mm medial rectus recession is larger in consecutive esotropes than in NAET, possibly due to previous resection of medial rectus or release of fat adhesion. Therefore the amount of medial rectus recession in consecutive esotropia should be determined after considering the degree of abduction and operative findings.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

Dysphagia is a dysfunction that occurs during the swallowing process, which involves the oral, pharyngeal, and esophageal stages of the swallowing route. Dysphagia is a prevalent symptom in elderly patients with degenerative diseases such as stroke, dementia, and Parkinson's disease. Dysphagia that occurs in the elderly is often caused by oral phase dysfunction. Oral phase dysfunction is a problem that occurs during the first stage of swallowing. The symptoms of age-associated dysphagia are the following signs: increased oral residual and longer mastication with slower oral bolus transit movement. Dysphagia can lead to malnutrition, dehydration, weight loss, functional decline, and fear of eating and drinking as well as a decrease in quality of life (QOL). Modification in viscosity and texture of food is usually helpful in resolving the nutritional problem of patients presenting signs of oral phase dysfunction. The degree of dietary modification can affect compliance of the diet. Adequate assessment and dietary modifications are important for successful dietary intervention for the elderly patients.
