Though high stone free rates were reported with ESWL monotherapy or anatrophic nephrolithotomy, percutaneous nephrolithotomy with or without ESWL appears to be the procedure of choice for most staghorn calculi. A total of 41 patients with staghorn calculi underwent percutaneous nephrolithotomy(PNL) alone or primary percutaneous debulking followed by extracorporeal shock wave lithotripsy(ESWL) of residual stone fragments. For the objective analysis of the results of PNL stone removal rate was calculated with stone surface area which was determined by computer analyzer. For staghorn calculi smaller than 2000 mm2(38/41), a mean stone removal rate of about 90% was achieved in the PNL. When stone surface area exceeded 2000 mm2(3,41), the mean stone removal rate was 78.8%. The stone removal rates stratified by stone surface area were not significantly different. The stone free rate was 31.7% in the PNL only but 75.6% in the PNL with or without ESWL. The higher mean stone removal rate and stone free rate was achieved in the kidneys with non-dilated collecting system than those with hydronephrosis, but it was not statistically significant.

The pathologic spectrums of the tennis elbow are varies as lateral epicondylitis, degenerative partial tear of extensor tendon origin, annular ligament lesion, synovial fringe between radio-capitellar joint, bursitis and posterior interosseous nerve pathology. So it is difficult to perform separate treatments for each different pathologic conditions. Conservative treatments for the tennis elbow are consisted of rest, immobilization, non-steroidal anti-inflammatory drugs (NSAID), and local injection of the steroid. Usual success rates of the conservative treatment have been reported approximately more than 90%. Several methods of surgical treatm nt of the resistant tennis elbow have been reported. Authors performed surgical treatment for twelve cases of the resistant tennis elbow from Jan. 1989 to Jan. 1994. Authors modified the Nirschl's technique; flap retraction of the extensor carpi radilais brevis (ECRB) and common extensor tendon to expose the radio-capitellar joint and no reattachment of detached tendons to the lateral epicondyle and side-to-side suture with maximal stretching of the ECRB tendon. Identified pathologic conditions were the degenerative partial tear and friable granulation tissues at the ECRB origin, sclerosis of the lateral epicondyle (ten cases), synovial fringe bewteen the radio-capitellar joint (two cases). In one case, authors couldn't find any abnormal pathologic conditions. Microscopic examinations (two cases) showed angioblastic proliferation, fibrosis, degeneration of the collagen fiber. Among these patients, eleven patients were industrial worker (eight painter, two welder and one carpenter). They have something in common with using hammer mainly. The hammering might be a possible cause of the tennis elbow. After the surgery, the functional recoveries were satisfactory. The final results were four excellent (33.3%) and good (66.6%) by Nirsh & ettrone grading system. The time required to return to the original job were varied from one month to eight months (average 4.3 months).

PURPOSE: Intussusception is one of the most common cause of childhood intestinal obstructions. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. METHODS: In order to evaluate the factors contributing to air-reduction failure, we reviewed cases of childhood intussusception admitted via the ER and managed by air enema reduction from 1994 to 1998. They were divided into two groups and compared retrospectively by using medical records. Group I was the operation group after air-reduction failure, and group II was the air-reduction group. RESULTS: In 319 cases (279 patients), group I consisted of 112 cases (110 patients), and group II consisted of 207 cases (169 patients). No differences in age, sex, body weight, location of intussusception, laboratory findings (leukocytosis and thrombocytosis), presence of bloody stool, and body temperature were noted between the two groups. Factors significantly contributing to air-reduction failure were duration of symptoms, type of intussusception and a few physical findings (abdominal distension, palpable mass, lethargy, and vomiting). The recurrence rate of group I was significantly lower than that of group II, and most recurrences developed in the first postoperative month. CONCLUSION: Childhood intussusceptions of a non-ileocolic type with longer durations of symptoms and severe clinical findings have a higher chance of air-reduction failure.

It is well known that mesenchymal stem cell originated from adjacent periosteum and bone marrow play an important role in bone regeneration process such as fracture healing, bone defect healing and distraction osteogenesis. Recently it has been reported that osteogenic stem cell mobilized from remote site can affect bone regeneration process and the role of angiogenic stem cell has been postulated. Angiogenic stem cell is characterized as cells that are mobilized from remote bone marrow and recruited to ischemic sites to enhance neovascularization. In this review, we will introduce recent studies on the role of angiogenic stem cells in bone regeneration process and suggest possibilities of therapeutic application of angiogenic stem cell based cell therapy for the enhancement of bone regeneration.

In order to investigate the level of anxiety, depression and repression, and the coping style in response to the stress of the delinquent adolescents, we examined 158 delinquent adolescents and 60 student adolescents using anxiety scale, depression scale, repression sensitivity scale and coping scale. Data were processed by IBM PC AT computer using SPSS program and were statistically analyzed by ANOVA. The level of anxiety, depression and repression of delinquent adolescents was significantly higher and the score of maladaptive coping scale was significantly higher than those of student adolescents. In conclusion, delinquent adolescents were more anxious, depressive, repressive, and more maladaptive than student adolescents.

The blood bank of the Seoul National University Hospital has joined the U.K. National External Quality Assessment Scheme(NEQAS) for Blood Group Serology since 1992. We reported correct answers on all occasions for thirty-six samples tested for ABO, RhD typing, and direct antiglobulin test. Among 36 antibody screening and antibody,,identification tests, we missed one anti-S. Among 96 crossmatchings, we made 4 major errors and one minor error. It was interesting that all of the major errors we made were from the sample delivered in mid-summer. Since the items included in the domestic program for the external quality control of blood group serology are very limited in Korea, joining any international quality control program will be necessary for larger blood banks to assure quality of varirous blood bank tests being performed.
