Uterine didelphys with unilateral hematometra, hemicolpos, and ipsilateral renal agenesis is a rare m01lerian duct malformation. Uterine didelphys with an obstructed hemivagina is frequently associated with renal agenesis, mostly ipsilateral to the blind vaginal pouch. Accurate early diagnosis and septal resection elevate pregnancy rate and birth rate but it is difficult to find these malfomations until the complication associated with pregnancy was developed. We report a case of successful gestational outcome in the presence of preterm labor due to hematometrocolpora caused by uterine didelphys with unilateral imperforated vagina and ipsilateral renal agenesis with brief review of the literatures.

BACKGROUND: Methicillin-resistant Staphylococcus aureus(MRSA) is an increasingly common cause of nosocomial infections worldwide. Epidemiologic investigation of MRSA outbreaks and identification of pathways of nosocomial MRSA spread require the ability to distinguish individual MRSA strains. We applied molecular tap ing of the methicillin-resistant determinant (mec) and coagulase typing in the investigation of a nosocomial MRSA infections. METHODS: We randomly selected 79 strains of mecA positive MRSA isolated from patients who visited Dong-A university Hospital from Dec. 1995 to Oct. 1996. Molecular typing of MRSA was performed by comparing the size of the mac-associated hypervariable region amplified by the polymerase chain reaction (PCR). Coagulase typing with type I-VIII antisera was also used for classification of MRSA based on its phenotype. Each isolates were classified by the combination of molecular analyses and coagulase type. RESULTS: The 79 MRSA isolates were grouped Into sin hypervariable legion (HVR) genotypes on the basis of the size of the PGR products. In coagulase typing, the most predominant type was II(46.8%) and type V was not found. Nine strains were not typable. The combination of HVR genotypes and coagulase types showed 23 different types in 79 MRSA Isolates. The strains which were repeatedly isolated from the same patients showed the same HYR genotypes and coagulate types. CONCLUSION: The combination of HVR genotypes and coagulase types is thought to be useful in epidemiolgical Investigation of nosocomial infections caused by MRSA ,because of its simplicity and reproducibility.

Classification of meniscal tear is necessary only for partial resection. In western countries many reports said that medial meniscal tear is commoner than that of lateral meniscus. Actually the reverse is true in Korea and in some other oriental countries, However there is no plausible explanation concerning this matter. In this report 250 knees of 240 patients were involved. We performed arthroscopic meniscectomy in all cases and we investigated the relationship between the pattern of tear and many possibly related factors. The follow-up period was 1–8 years, the ratio of male-female was 163:77, and the range of age was varied between 7 and 71 tears with the young and middle age groups being predominant. Right and left side ratio was 117:113 and the involvement of both knees was noted in 20 knees of 10 patients. The results were as follows: 1. The medial menisci were torn in 100 knees and was less than 142 lateral meniscal tear, with the ratio being 1:1.4. The tear of lateral meniscus was commoner in the age group of less than 30 years and the tear of medial meniscus was commoner in the age group older than 50 years whereas there was no difference in the age group of inbetween. 2. The commonest pattern of tear was longitudinal one including peripheral tear, that is 135 knees (54.0%), followed by complex tear, 50 knees (20.0%), oblique tear, 40 knees (16.0%), horizontal tear, 21 knees (8.4%) and lastly superior and inferior flap tear, 5 knees (2.0%). 3. The longitudinal tear was most prevalent in the age group of 20–40, whereas the complex tear was most prevalent in the age group of beyond 50 years (p<0.05). 4. The longitudinal tear was significantly prevalent in lateral menisci, the complex tear in medial menisci (p<0.05), whereas the transverse and oblique tear were not significantly prevalent in either meniscus (p>0.05). 5. In the longitudinal tear group, the tear occured most frequently in the midsubstance of posterior portion in the medial menisci without statistical significance (p>0.05) wereas the tear occurred most frequently in the periphery of the anterior portion in case of lateral menisci (p<0.05). 6. There were 37 discoid lateral menisci, with the longitudinal tear being the commonest. 7. Ground sports injuries occurred only in 34 knees (13.6%), with the longitudinal tear being significantly commoner than in the other injuries. From these results it would be suggested that although the discoid lateral meniscus has to be given much weight in the total meniscal injuries another explanation should be given concerning the prevalence of lateral meniscus tear compared to the medial meniscus tear and the prevalence of longitudinal tear.

Purpose: A retrograde intramedullary nail is commonly used to treat femoral shaft and distal femur fractures. The authors analyzed the treatment results and the factors affecting the period of bone union for thirty-five patients treated with a retrograde intramedullary nail. Materials and Methods: Thirty-five patients who could be followed up for more than twelve months after the treatment with retrograde intramedullary nailing were analyzed retrospectively. The treatment results and the relationship between the period of bone union and the patient’s age, sex, comminution of fracture, presence of open fracture, location of the fracture, and accompanying fractures were evaluated. Results: The average bone union time was 4.50 months. The period of bone union was unaffected by the age, sex, location, and presence of open fractures but was affected by the presence of comminution and accompanying fractures. Conclusion Retrograde intramedullary nailing is effective for distal and shaft of fractures of the femur. The period of bone union is affected by the presence of comminution and accompanying fractures.

CHAP syndorme consists of choreoathetosis, orofacial dyskinesia, affective change, hypotonia, and pseudobulbar signs. CHAP syndrome was firstly des- cribed with onset 1 to 7 days after induced profound hypothermia and complete circulatory arrest for con- genital heart lesion repair. Since then, only a few cases have been reported until now. Case We report a patient who demonstrated all of the elements of the CHAP syndrome in severe cachexic state. Brain SPECT(99mTC-ECD) shows decreased perfusion in left fronto-parieto-temporal lobe. Comments The pathogenesis of CHAP syndrome is obscure. However our case led us to suggest that more essential component pre- disposing to the CHAP syndrome is hypoxia rather than hypothermia. Furthermore, it seems to be related with circulatory insufficiency in extrapyramidal nervous systems.

We performed a retrospective analysis of twenty-four consecutive hip arthroplasties (Total Hip Arthroplasty 18, Bipolar Arthroplasty 1, Cup revision 5) during which intraoperative frozen sections were analyzed to identify the occult active infection. We also reviewed the data such as laboratory findings (ESR, CRP), intraoperative culture, hip joint sonographic evaluation and permanent histologic section. Among the twenty-four patients those who received hip arthroplasties, 10 cases received revisional hip arthroplasties due to painful hip prosthesis loosening, 9 cases with infected hip prosthesis, 3 cases with infection after open reduction and internal fixation due to hip fracture and 2 cases with septic hip sequelae. Intraoperative frozen section had been obtained during staged revisional hip arthroplasties to determine the presence of active infection. We considered positive for infection if it shows more than 10 PML/HPF (Polymorphonuclear leukocyte /high power field) in at least 5 distinct microscopic fields from intraoperative tissue frozen section and postponed implantation of prosthesis. If it shows less than 5 PML/HPF, we performed revisional hip prosthesis implantation. We decided the implantation based on patient's condition, laboratory findings and intraoperative tissue conditions if it shows between 5 and 10 PML/HPF from intraoperative frozen section. At last follow up, 20 of 21 patients who had a revisional hip arthroplasties as below 10 PML/HPF from intraoperative frozen section remained free of infection (Specificity; 95%). We concluded that analysis of the intraoperative frozen sections is a reliable predictor as a guide to sepsis for the successful hip joint arthroplasties.

Two cases of exercise-induced atrial fibrillation were diagnosed in 68 years old female and 47 years old male. They complained palpitation during exercise, and emotional upset for the last 5 years. There was no evidence of organic heart disease except mild hypertension in female patient. The atrial fibrillation was induced repeatedly by treadmill exercise test and intravenous infusion of isoproterenol. The beta blocker(atenolol 50mg po dialy) prevented the induction of atrial fibrillation during treadmill exercise. We report two cases of exercise-induced atrial fibrillation which is very rare and might be related to catecholamine.

Power lawn mower is a useful equipment for landscape, but it can introduce a new eye trauma. These ocular injuries are recently increasing in Korea. To inform the possibility of visual loss, we reviewed medical records of 11 patients with intraocular foreign bodies by power lawn mowers. All of patients were men and lawn mower operators themselves. Nature of foreign bodies was metallic in 10 eyes(91%), Inlet was through the cornea in 10 eyes(91%), and intraocular location was at the vireo retina in 8 eyes(73%). At final follow-up, best corrected visual acuities were worse than counting fingers in 4 eyes(36%). Safety cover or halmet is needed for prevention of eye trauma caused by power lawn mower, however, more important, operators themselves should follow the ordinary safety rules.
