Methods of management of Legg-Calve-Perthes Disease (LCPD) are at present controversial. Some practical prognostic indices were imperative for proper management of the disease. .We followed up on twenty LCPD patients-14 who underwent varization osteotomy of proximal femur and 6 who underwent pelvic innominate osteotomy or shelf procedure-for more than 3 years and analyzed the results using the Stulberg classification. There were three requirements for the hip to be included in this study: follow-up until residual stage occurred, Catterall group III or IV and complete clinical and radiological data. The purpose of this study-was to determine the validity of radiological and clinical factors in predicting prognosis in surgical treatments. Results of the evaluation were as follows; 1.Age was found to be an important prognostic index. Older children aged > 9 years tended to do worse than younger children (P<0.05). Other prognostic indices were not found to be statistically significant. 2. When Stulberg classification IV atients were considered, there were common factors in the children who were more than 9 years old, were of Catterall group IV, and late fragmentation stage disease with more than 1.5 of the lateral subluxation index, regardless of treatment. 3. Although Catterall's classification had been widely accepted, Catterall group III or IV seemed to be difficult to be distinguished. Many cases that had been regarded as Catterall group IV were proved to have intact posteromedial portion of femoral head later in residual stage. 4. Even though well-known prognostic indices were important in anticipating the results, we considered additional unknown biomechanical factors. In some cases continuous deformation of femoral head would not be prevented even though necrotic portion of femoral head was well contained by surgical treatment.

The authors introduced flip back spin echo (FBSE) technique for MR imaging of the temporomandibular joint (TMJ) instead of conventional spin echo (SE) technique, and evaluated whether FBSE technique in MRI of TMJ is adequate for the diagnosis of the disorders or not. FBSE T1 parasagittal images in closed mouth state and sequential opening and closing mouth states using patient's own finger(s) were obtained and then FBSE T1 paracoronal image in closed mouth state and STAGE(short tip angle gradient echo) parasagittal T2WI were followed. All 30 images of the symptomatic TMJs using FBSE technique were excellent in the visualization of articular and their displacement, and we could easily diagnose the internal derangement. FBSE technique was adequate for the diagnosis of internal derangement of the TMJ, and the modified cine display from images using FBSE technique was advantageous in the diagnosis of the disorders by visualization of the dynamic motion of the TMJ.

PURPOSE: The purpose of this study is to find some points that may help the differential diagnosis of ring lesions in magnetic resonance (MR) imaging of the liver through recognition of the characteristics of the morphology and the signal intensities of the ring lesions. MATERIALS AND METHODS: T1- and T2-weighted axial spin-echo images and gadolinium-enhanced Tl-weighted images were obtained with a 1.0 T superconducting MR imager. We reviewed the MR findings of 23 hepatic ring lesions which were confirmed as hepatocellular carcinomas (13), metastases (4), liver abscesses (4), hydatid cyst (1), and hematoma (1). RESULTS: There were 19 single rings and 4 double rings (all the cases were liver abscesses) on Tl-weighted images, and 8 single rings and 14 double rings on T2-weighted images. The signal intensity of the ring was low in hepatocellular carcinoma on Tl-weighted images and in hydatid cyst on T2-weighted images. It was high on Tl-weighted images in subacute hemaroma. Target lesion as an inner high-signal-intensity ring surrounded by a high-signal-intensity ring on T2-weighted images was seen in metatasis, liver abscess, and hepatocellular carcinoma. CONCLUSION: It is helpful to recognize the chracteristics of morphology and signal intensities of the ring lesions in the differential diagnosis of hepatic focal lesions.

We experienced a case of congenital tuberculosis infected in utero, who had been found to have massive ascites and pleural effusion on routine ultrasonography at the 39 weeks' gestation. The emergency C-section delivered a male neonate weighing 2,050 g with poor condition and in severe respiratory distress. He was the first child born of a 27-year-old woman, who was diagnosed as having tuberculous pleurisy after delivery. Detection of acidfast bacilli in gastric aspirates obtained from the newborn as well as the clinical features and maternal history confirmed the diagnosis of congenital tuberculosis. Though rare, congenital tuberculosis requires early detection and treatment because of its severity and high mortality. A brief review of the relevant literature was made.

BACKGROUND: As invasive streptococcal infections are increasing recently and the resistance rate to either erythromycin or clindamycin is elevating, epidemiologic surveillance and appropriate guideline for antibiotic use are required. Geographical epidemiologic characteristics with T typing and antibiotic resistance rate were investigated. METHODS: Distributions of T types according to geographical areas and sources of specimens were analyzed with 82 strains of Streptococcus pyogenes isolated from clinical samples in Seoul and Chinju. Antibiotic susceptibility test was performed for penicillin G, cephalothin, erythromycin, azithromycin, clarithromycin, clindamycin, chloramphenicol, and ofloxacin with agar dilution method. Antibiotic resistance rates were analyzed according to geographical areas, sources of specimens and T types. RESULTS: The most common T types were T12, T1 and T28 in decreasing order. The distribution of T types between Seoul and Chinju was different. While T1, T3, and T6 were frequent in throat or other respiratory specimens, T12, T28, and B3264 were common in blood or closed pus. The resistance rate to erythromycin, azithromycin, and clarithromycin was 20%, 13% to clindamycin, and 49% to tetracycline, respectively. None of the isolates were resistant to penicillin G, cephalothin, chloramphenicol, or ofloxacin. The isolates from Chinju showed higher resistance rate than the strains from Seoul. The isolates from blood or closed pus had higher resistance rate compared to those of throat or sputum. T28 and T6 strains presented higher resistance rate than other T types. CONCLUSIONS: As distributions of T types were variable according to geographical areas or sources of specimens, continuous microbiological and epidemiological surveillance for invasive streptococcal infections are needed. Minimizing unnecessary antibiotic use or acknowledging the severity of resistance are necessary, because the resistant proportions are increasing against macrolide, clindamycin and tetracycline.

Heterotopic pregnancy is the coexistency of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy is about 1 to 30,000 pregnancy in a natural cycle. However, the frequency of heterotopic pregnancy has steadily increased because of rising incidence of pelvic inflammatory disease, pelvic surgery and the development of ovulation induction and assisted reproduction. Because heterotopic pregnancy is difficult to diagnose and it has high morbidity and mortality rate, one should always take this into consideration and should conduct careful and thorough gynecologic evaluation. We have experienced a case of heterotopic pregnancy in a 29-year old woman who presented with acute abdominal pain in a natural cycle and report this case with a brief review of literature.

BACKGROUND: Antistreptolysin O (ASO) has been widely used to diagnose Streptococcus Pyogenes infections and their sequelae, rheumatic fever and acute glomerulonephritis. Butt in some cases there is no elevation of ASO that it is necessary to add one or more tests detecting immune response to S. pyogenes.. The authors analyzed the distribution of antideoxyibonuclease (ADNase) B and antistreptolysin O (ASO) among the children of an elementary school in Seoul and calculated their upper limit of normal (ULN) value. METHODS: ADNase B concentrations were determined by nephelometry (Behring Nephelometer 100 Analyzer, Germany) on 236 sera of healthy elementary school children in Seoul. Throat cultures were taken at the same time to compare ADNase B lovels between S. pyogenes carriers and non-carriers. RESULTS: The distribution of ADNase B concentrations among school children ranged from 77 (detection limit) to 1616 IU/ml and the ULN was estimated to be 362 IU/mL. The carriers of S. pyogenes clad significantly higher ADNase B levels (mean 392 IU/ml) than carriers of non-group A beta-hemolytic streptococci (BHS, 236 IU/ml) oY non-carriers of BHS (234 IU/ml). The relationship between ADNase B (Y) and ASO (X) levels was Y=0.4X+173 (r2=0.209). CONCLUSIONS: The distribution of ADNase B levels showed no close correlation with that of ASO, and ADNase B test was considered to have additive value to ASO test for detecting S. pyogenes infection.

PURPOSE: We wanted to review the clinical results of staged reimplantation in patients who had candidal infection after total knee arthroplasty. MATERIALS AND METHODS: We reviewed five patients who had a candidal prosthetic knee infection, as was assessed by synovial fluid culture. Amphotericin B was intravenously administrated to all five patients during the postoperative period for six weeks and followed for at least twelve months. We carried out two-stage re-implantations with using antifungal agent-impregnated bone cement. Whether or not infection recurred was evaluated according to the symptoms and radiologic and hematologic studies. The clinical results were analyzed on the basis of the range of motion and hospital for special surgery (HSS) score. RESULTS: The final review showed that all of the symptoms disappeared. We could not find any loosening on the radiologic studies and all five patients had normal C-reactive protein values on serological exams. The mean postoperative range of motion was 1degrees (range: 0~5)~99degrees (range: 70~130) and the mean HSS score improved from 49.4 (range: 44~64) points to 73 (range: 65~90) after the re-implantation. CONCLUSION: We successfully controlled five candidal prosthetic knee infections by removing the components in conjunction with using an antifungal- impregnated bone cement and staged re-implantation after a 6 week course of intravenous antifungal drugs.
