Fractures of the proximal humerus occur more frequently in older patients but are seen in all ages and emerge epiphyseal separations. The objectives of treatment are restoration of all involved structures to normal anatomical state and a completely functional limb in the shortest time possible. One part and two part fractures were indicated in conservative treatment and surgical treatment in most of three, four part fractures. The results of treatment of forty four cases according to Neer's classification were analysed at the Department of Orthopedic Surgery, Chonbuk National University Hospital from Mar. 1978 to Dec.1985. The results were as follows. 1. The prevalent age distribution was third and fifth decade(48%) . 2. The most common cause of injury was slip down(14 cases, 32%). 3. The most frequent cases of the fractures in Neer's classification were two part fractures(22 cases, 50%). 4. Thirty one cases(71%) were treated by conservative treatment, twelve cases(27%) by open reduction and 1 case(2%) by prosthesis. 5. Good results were in 23 cases(52%) of one and two part fractures, fair in 17 cases(39%) and poor in 4 cases(9%) of two, three and four part fractures.

BACKGROUND: To access the accuracy and clinical usefulness of microplate identification (ID) system for the identification of Enterobacteriaceae, we compared microplate ID system with API 20E(bioMerieux, Etoile, France). METHODS: Ninety-two cultures of Enterobacteriaceae and one isolate of Aeromonas species were simultaneously identified by microplate ID system and the API 20E. Twenty biochemical tests used in microplate ID system were lactose, sucrose, and H2S in Kligler's iron agar media; indole, sucrose, raffinose, arabinose, trehalose, adonitol, dulcitol, sorbitol, cellibiose, methy-red, phenylalanine deaminase, ornithine decarboxylase, lysine decarboxylase, arginine dihydrolase, urease, and citrate in microplate; and oxidase test. The identification was obtained by considering percent likelihood(% ID), modal frequency and ID score method. RESULTS: Among the 92 cultures of Enterobacteriaceae and one isolate of Aeromonas species, agreement rate of identification according to the % ID between microplate ID system and API 20E were 90.3% to the species level and 97.8% to the genus level. CONCLUSIONS: For the identification of clinical Enterobacteriaceae isolates, the microplate ID system compares favorably with API 20E in identification accuracy and have the advantage of costsaving and easy to use.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.

BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

BACKGROUND: The erythromycin-resistance rate and phenotype distribution of Streptococcus propenes are quite different by geographical variation and study period. The aim of the present study was to determine the evolution of resistance to erythromycin and the frequency of erythromycin resistance phenotype of S. pyogenes isolated from Wonju Christian Hospital. METHODS: The minimal inhibitory concentrations (MICs) of erythromycin and clindamycin for 94 S. pyogenes isolated from clinical specimens between 1990 to 1998 were investigated. Double disk test of erythromycin (78microgram) and clindamycin (25microgram) were performed for 15 isolates of erythromycin resistant S. pyogenes to evaluate the erythromycin resistance phenotype. RESULTS: The resistance rates of 94 isolates of S. pyogenes were 16%(15/94) to erythromycin and 4%(4/94) to clindamycin. The frequency of erythromycin resistance phenotype in decreasing order were M phenotype (47%), inducible resistance phenotype (40%), and constitutive resistance phenotype (13%). Erythromycin-resistant S. pyogenes did not exist until 1993, but was isolated since 1994, and ranged from 14.0% to 24.0% during the period of 1994-1998. CONCLUSIONS: Our finding documents the emergence of high resistance rates to erythromycin in S. pyogenes at Wonju area since 1994. The M phenotype (47%) and inducible resistance phenotype (40%) account for the majority of erythromycin-resistant S. pyogenes.

BACKGROUND: Recent data suggest that the colonization rate of group B streptococci(GBS) in pregnant women and the incidence of neonatal infections by GBS is increasing trend in Korea, but the antimicrobial susceptibilities and serotypes in pregnant women have not been reported in Korea. So, we studied to define the antimicrobial susceptibility patterns and frequency of serotypes of GBS in pregnant women. METHODS: The susceptibility and serotyping of 60 GBS isolates from 27 pregnant women and four isolates from their two neonates were tested by an agar dilution method and agglutination test, respectively. The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Minimal inhibitory concentration range of 60 GBS from pregnant women were penicillin G 0.015-0.12 microgram/ml, vancomycin 0.5-2 microgram/ml, clindamycin 0.015-4.0 microgram/ml, chloramphenicol 2-4 microgram/ml, erythromycin 0.015-2 microgram/ml, tetracycline 0.5-256 microgram/ml, cephalothin 0.12-0.25 microgram/ml, ceftriaxone 0.03-0.12 microgram/ml, respectively. The resistance rate of GBS were 6.7% to clindamycin, 0% to erythromycin, and 98.3% to tetracycline. Most of GBS serotypes from pregnant women in decreasing order were Ib(48.3%), Ia(24.1%), III(20.7%). CONCLUSION: All GBS strains isolated from pregnant women are highly susceptible to commonly used antimicrobial agents with the exception of tetracycline. The low prevalence of severe neonatal GBS infections in Korea is not due to the absence of serotype III, but probably due to a low genital carriage rate of GBS by pregnant women.
