Reviewing the results of the blood cultures performed at Yeungnam University Hospital during 4-year-period through January, 1, 1984 to December 31, 1987, the following results were obtained. 1) Out of 8083 blood specimens cultured microorganisms grew in 582 specimens with positivity rate of 7.20%. Polymicrobial bacteremia was found in 16 patients. 2) Among 582 positive specimens, Gram-positive cocci grew in 189 specimens, and Gram-negative bacilli, in 393 specimens. Clinically significant microorganisms consisted of 82 Staphylococcus aureus, and 20 Streptococcus species in Gram-positive cocci group, 80 Salmonella typhi, 72 Escherichia coli, 72 Salmonella paratyphi A in Enterobacteriaceae, and 46 Pseudomonas cepacia, and 16 Pseudomonas aeruginosa in glucose non-fermenting microorganisms. 3) Increasing incidence of Serratia, Acinetobacter and Pseudomonas species as major nosocomial infection source is noteworthy. They showed increased tendency from 6.3% of 1984 to 17.7% of 1987 of total positive blood cultures. 4) High isolation rate of Pseudomonas species and Aeromonas hydrophila was noted in summer, while Salmonella typhi showed high prevalence from May to September and in January. 5) In susceptibility tests of isolated organisms, staphylococcus aureus was sensitive to basic antimicrobial agents except for ampicillin. The glucose non-fermenting microorganisms showed high resistance to basic antimicrobial agents in 32.2%. In conclusion, considering the relatively higher incidence of growth of Staphylococcus epidermidis than ideal level indicates that sampling technique should be improved. Secondly, all the hospital staffs in cooperation with Hospital Infection Committee are desirable to pay efforts to decrease the nosocomial infection.

The purpose of this study was to analyze the growth and development of tooth germ and dental arch related to the bone growth during the fetal period. From 70 maxillae and 61 mandibles of the fetus aged 5, 6, 7, 8, 9 and 10 months, X-ray films were taken and measured. The results were as follows; 1. There was remarkable bone growth in the anterior and posterior area of palatum osseum, that were the interior portion of both deciduous canines anteriorly and the intero-posterior portion of both deciduous second molars posteriorly, where there was active bone growth and radiate formation of bony trabecylae was found. 2. The Growth of anterior tooth germ was greater than that of posterior germ, so anterior tooth germs were crowded. Especially in maxilla, the tooth germa of deciduous lateral incisors were located inside of dental arch and the tooth gerka of decoduous canines were located outside of dental arch. 3. Crowding amount increased with the fetal age because the growth of tooth germs was grdater than that of jow bone. 4. In the growth of upper dental arch, the increase of width was greater than that of length. 5. There was proportional relationship beween the arce of Palatal Trapezoid and the fetal age.

INTRODUTION: The gamma-aminobutyric acid type A (GABAA) receptor is an important pharmacological target of alcohol. The phamacological characteristics of the receptor are largely determined by its subunit composition. Compared with all other alpha subtypes, the alpha6- containing receptors are more sensitive to GABA and less sensitive to benzodiazepines. The purpose of this study was to address a role for GABAAalpha6 receptor subunit gene in the development of alcohol dependence. The differential manifestation of alcohol withdrawal symptoms related to GABAAalpha6 polymorphism in patients treating with benzodiazepines was also examined. METHODS: Eighty-seven inpatients with alcohol dependence, and sixty healthy controls were evaluated using CIWA-Ar scale. Each patient was genotyped for GABAAalpha6 subunit. Association between GABAAalpha6 polymorphism and severity of withdrawal symptom were determined. RESULTS: No significant difference was found in GABAAalpha6 receptor genetic type and allelic distribution between the alcohol dependent and control subject. Tremor was more severe in CC than TT type. TT type had higher degree of anxiety, agitation and headache than CC type. The GABAAalpha6 C allele increased the average score of tremor significantly, and T allele increased that of agitation. CONCLUSION: The results suggested that GABAAalpha6 genetic polymorphism was not associated with alcohol dependence and with severity of alcohol withdrawal symptoms. But in benzodiazepine treated patients, GABAAalpha6 polymorphism and allelic type show the difference in severity of each withdrawal symptom. These differences of severity are partly responsible for the unique pharmacological properties associated with the GABAAalpha6 subunit.

Multifocal fibrosclerosis, a rare disorder, has no known etiology and is considered to be a systemic illness manifested by combinations of fibrosing process of multiple areas such as mediastinal fibrosis, retroperitoneal fibrosis, orbital pseudotumor, sclerosing cholangitis, and Reidel's thyroiditis. We have experienced a 49-year-old man with pseudotumor of the orbit, sclerosing cholangitis, and CNS involvements included unrecognized meningitis and suspicious CNS vasculitis. The patient showed clinical improvement with corticosteroid therapy.

Non-specific periventricular white matter lucencies on computed tomography(leukoaraiosis) were found in 130(40%) of 324 patients with ischemic or hemorrhagic strokes. Patients with leukoaraiosis were significantly older than those without it and correlated with hypertension and lacunar infarction but not with cortical infarction. In patients with hemorrhage, leukoaraiosis occurred sinigificantly more often when aneurysm or arteriovenous malformation were not demonstrated. Our fiindings suggest that leukoaraiosis in cerebrovascular disease is associated with small vessel disease.

Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.

PURPOSE: To determine the value of an anatomic distal radio-ulnar joint ligament reconstruction (Adam's technique) in patients who suffer chronic pain related to distal radio-ulnar joint instability. MATERIALS AND METHODS: Twelve patients who suffered from chronic pain related to distal radio-ulnar instability and underwent a reconstruction of the distal radio-ulnar ligament using a free tendon technique were enrolled in this study. The mean follow up period was at least 1 year. In all cases, injury to the distal radio-ulnar joint was present, which had been previously treated with conservatively. There was no evidence of arthritis on the distal radio-ulnar joint radiologically. The radiological radio-ulnar space and displacement of the ulnar head, clinical pain, stability, the range of motion and the grip power were measured before and after surgery (follow up 1 year). RESULTS: No displacement of the distal radio-ulnar joint or prominence of the ulnar head was observed radiologically in 10 cases, and only partial subluxation was present in 2 cases. Clinically, the pain disappeared in 8 cases and the stability of the joint was recovered in 8. The mean pronation, supination range and grip power increased by an average of 73, 71 degrees and 11.7 kg, respectively. CONCLUSION: In treating distal radio-ulnar joint instability related to chronic pain, Adam's technique using palmaris longus, which is an operation using a single incision, and by restoring the distal radio-ulnar ligament anatomically can decrease the level of pain and recover the range of motion. Therefore, it is a good method worth considering in this situation.

Extracorporeal shockwave therapy (ESWT) has been reported to be a safe and effective method for decreasing pain and relieving range of motion (ROM) limitations caused by neurogenic heterotopic ossification (NHO), though there has been no report that it might cause hematoma if applied to NHO. We hereby report a case of massive hematoma after ESWT, specifically the radial shockwave therapy (RSWT) device at both hips in a 49-year-old female patient with NHO. She had developed NHO after extensive subarachnoid hemorrhage. We had applied RSWT according to the previous report. The pain and the ROM limitations were gradually improved. Six weeks later, she reported pain and ROM limitations on the right hip. From a medial aspect, swelling and bruising of the right thigh could be seen. Magnetic resonance imaging and ultrasonography suggested a large hematoma between right hip adductor muscles. The symptoms disappeared after conservative treatment for one month, and subsequent follow-up imaging studies demonstrated resolution of the hematoma.

PURPOSE:To analyze the clinical aspects and risk factors for recurrent herpes simplex keratitis (HSK) after penetrating keratoplasty (PKP). METHODS: Records from 78 eyes of 41 patients who underwent PKP for HSV keratitis with a mean follow-up duration of 31.83+/-21.35 months (24~97 months) were reviewed. The clinical aspects of recurrent keratitis, rejection, and survival rate were evaluated. Previous operation history, preoperative inflammation and neovascularization, graft size, suture methods, and antiviral use were analyzed to elucidate the risk factor for recurrent HSK after PKP. RESULTS: HSK recurred in 47.4% of the patients at a mean time of 18.36+/-21.02 months after PKP. The mean duration of keratitis was 2.16+/-1.71 months and the mean frequency of recurrence was 1.41+/-0.69 times. Epithelial keratitis developed in 46.2% of the patients, and epithelial keratitis combined with stromal inflammation developed in 36.5%. Previous graft failure due to recurrent HSK and preoperative inflammation were significant risk factors for recurrent HSK after PKP (p=0.019, p=0.006). There were no statistically significant differences in graft rejection and survival rate between the two groups with and without recurrent HSK. CONCLUSIONS: The majority of cases of recurrent HSK after PKP were epithelial keratitis or epithelial keratitis combined with stromal inflammation, and risk factors for the recurrence of HSK were previous graft failure due to recurrent HSK and preoperative inflammation.
