The role of the long head of biceps brachii tendon in the stahilization of the head of the humerus is a highly interesting issue in recent studies. But, it is not well understood. Congenital absence of biceps long head tendon ot the hilateral shoulder joint is very rare and on review of literatures, we could not find any case reported. We experienced one case which was confirmed by magnetic resonance imaging and arthroscopic examination of the shoulder, and report it with review of literatures.

BACKGROUND: Percutaneous Mitral Valvuloplasty (PMV) is the first-line treatment modality in selected patients with symptomatic mitral stenosis and more recently available Inoue single-balloon catheter technique produces good results with low incidence of complications. The purpose of this study was to evaluate the immediate and over 6 months follow-up results after successful PMV with an Inoue balloon and to identify the predictive factors for the results. METHODS: From May 1995 to Feburary 1997, a PMV with an Inoue balloon was tech-nically successful in 114 (95%) of the 119 patients treated at the Sejong General Hostpital. In this study, a series of echocardiographic follow-up were performed in 54 patients with rheumatic mitral stenosis, at least 6 months after their successful PMV. In PMV, the inflation was conducted in steps, starting with a recommended maximum size of balloon by the Inoue criteria. After each inflation, the mitral valve opening and competence were evaluated by Transesophageal echocardiography (TEE) and continuing increase balloon size. RESULTS: Echocardiographic follow-up assessment was performed in 54 patients serially in a interval of 3 months or 6 months. Their mean age was 46+/-11 years (24 to 66 years) and the mean total echocardiographic score was 7.1+/-1.6. A optimal result was obtained in 95% of the cases (51/54). The post-PMV mitral valve area increased to 1.95+/-0.37 cm 2 and 1.79+/-0.28 cm 2 by 2-D and Doppler method, the average transmitral mean diastolic pressure gradient decreased to 5.16+/-2.8 mmHg and LA pressure was decreased to 11.28+/-8.2 mmHg. The newly developed and aggravated mitral regurgitation was observed in 17 patients (31.5%). The restenosis was noted in 2 cases (3.7%) after 1 year follow-up. The pre-procedural echocardiographic score for leaflet mobility, thickening and calcification was more higher in patients with restenosis. There was significant tendency of decrement in the mitral valve area in patients with a echocardiographic score=8 compared with those< or =8 over 6 months after the PMV. CONCLUSION: PMV with the Inoue balloon under TEE guide as a combined treatment modality of patient with symptomatic mitral stenosis is relatively safe and achieves good immediate and midterm follow-up results. The echocardiographic score is considered as useful predictor of midterm results and restenosis after PMV with Inoue balloon.

The high osteogenic potential in children can lead to the spontaneous regeneration of a significant bone loss, however, the site documented in the previous reports was limited to the diaphysis in long bones. We report an exceptional case of a spontaneous regeneration of the whole lateral malleolus, including epiphysis, physis, and metaphysic, after traumatic loss in a three-year-old boy. This case emphasizes the importance of attempts to save as much of the cartilaginous tissues and the periosteum as possible, which have a great osteogenic potential, in themanagement of open would in childrhood.

We report a case of right broad ligament tumor with features of female adnexal tumor of probable wolffian origin. A 40-year-old woman presented with dysfunctional uterine bleeding. Ultrasonography revealed 1 10cm sized right parovarian solid mass. On microscopic examination, the tumor showed mixed pattern of tightly packed tubular structures and diffuse spindle cell proliferation. Immunohistochemical study demonstrated cytokeratin-and vimentin-positivity and carcino-embryonic antigen-negativity. The ultrastructural study showed prominent tubular structures, continuous basal lamina, definite junctional complex but no secretory granules or glycogen particles, favoring wolffian origin.

Submerged implants require secondary surgical uncovering of implants after healing period of 3 - 6 months. In surgical methods, there are surgical scalpel, tissue punch, electro-surgical, and laser-used uncovering, and laser-used uncovering, and so forth. The objectives of this study are investigation and assessment of 1) thermal change in clinical application for uncovering of HA-coated implant and pure titanium implant irradiated by pulsed Nd-YAG. CO2, and Er-YAG laser. 2) surface change of cover screws after irradiation using laser energy. The temperature of apex & side wall of implants were recorded at 10sec, 20sec, 30sec after 30sec irradiation to implant healing screw; 1) pulsed Nd-YAG laser; 2W, 20pps, contact mode 2) CO2 laser; water-infused & non-water infused state, 2.5-3.5W, contibuous mode, noncontact mode 3) CO2 laser; non-water-infused state, 3W, superpulse, noncontact mode 4) Er-YAG laser; (1) non-water infused state, 10pps, 60mj, contact mode (2) water-infused state, 10pps, 60mj, 80mj, 101mj, contact mode According to the results of this study, pulsed Nd-YAG laser is not indicated because of increase thermal change and pitting of metal surface of implant cover screw. By contrast, CO2 laser & Er-YAG laser are presumed to indicate because of narrow range of thermal change & near abscence of thermal damage of metal surface. Dental laser is thought to be much helpful to surgical procedure when it is used as optimal power and time condition considering characteristics and indications of each laser. Further research is needed to verify that these techniques are safe and beneficial to implant success.

BACKGROUND: Serologic markers are used to screen and diagnose the hepatitis B virus infection. In endemic area of hepatitis B, the coexistence of HBsAg and anti-HBs was frequently observed. This finding is unusual and difficult to interpret. In this study, we performed three molecular biologic assays-polymerase chain reaction (PCR), chemiluminescent molecular hybridization assay (CMHA), branched DNA (bDNA) nucleic acid hybridization assay- to detect HBV-DNA in the sera which showed both HBsAg and anti-HBs positivity. To define the patients` exact clinical conditions, we analysed the characteristics of the patients according to their diagnoses, other serologic markers and clinical findings. METHODS: HBsAg and anti-HBs were detected by EIA (Enzygnost, Behringwerke, Germany) from clinical specimens of Yonsei University College of Medicine Severance Hospital collected In the period between January 1996 and December 1996. Eighty three specimens from Severance Hospital and twenty two specimens from Health Care Center were randomly selected and were subjected to HBV PCR, HBV CMHA and HBV bDNA assay for the presence of HBV-DNA. RESULTS: The patients were arbitrarily divided into 4 groups on the basis of the optical density values of enzyme immunoassay results. Group I (high HBsAg and high antral-HBs) consisted of 6 cases; group II (high HBsAg and low anti-HBs) consisted of 70 cases, group III (low HBsAg and high anti-HBs) consisted of 1 case; group IV (low HBsAg and low antral-HBs) consisted of 6 cases. Among 83 cases, the positive rate was 51.8% (43 cases) using PCR method, 53.0% (44 cases) using CMHA, 60.2% (50 cases) using bDNA assay. HBeAg and anti-HBc IgM were helpful to predict the presence of HBV-DNA in the sera. CONCLUSIONS: More than half of the patients who showed both HBsAg and anti-HBs positivity were positive for HBV-DNA by molecular biologic methods. In contrast, no one whose serologic markers with only anti-HBc positivity with out HBsAg and anti-HBs positivity showed HBV-DNA positive in the sera from Health Care Center. Taken together, the management and follow-up of the patients of both HBsAg and anti-HBs positivity could be greatly aided by combined adoption of any one molecular biologic assay of HBY-DNA with other serologic markers such as HBeAg and anti-HBc IgM.

Histiocytosis X patients present with a variety of clinical manifestations and outcomes. The principal difficulty in the establishment of a definite protocol for treatment is based on the poor understanding of the basic nature of this disease, the absence of reliable prognostic criteria, and the problems with nomenclature. The objectives of this study were to analysis the course of the disease and the results of treatment in patients who had Langerhans cell histiocytosis and to suggest prognostic factors and guidelines for management. We reviewed the thirty patient who had Langerhans cell histiocytosis for past ten years. These patients were followed for an average 4.8 years (range, excluding patients who died of the disease, two to eleven years). The patients were divided into tow group; eighteen patients who Langerhans cell histiocytosis localized in skeleton (group I) and twelve patients who had Langerhans cell histiocytosis disseminate in both skeleton and extra-skeleton (group II). Methods of treatment included curettage with or without bone graft, radiotherapy, or watchful observation alone in group I; chemotherapy, chemotherapy and radiotherapy, or curettage in group II. All eighteen patients in group I had a complete response to the therapy. Seventeen of these eighteen patients had not a recurrence by the time of the latest follow-up examination; one had a recurrence. Four of twelve patients in group II had a complete response to the therapy, four had a partial response, and four had no response. Eight of these twelve patients had a recurrence; four did not. Two patients in group II died of the disease. The significant prognostic factor was the extent of the disease, limited to the skeleton or not, and the age of onset was an indirect prognostic factor predictin multiple organ involvement.

Interstitial cell tumor of testis is relatively rare, comprising only 0.8 to 1.4 percent of all testicular tumors. A 67-year-old man was admitted to our hospital with rapid growing testicular mass. He had the experience of hydrocele and many times of aspiration since childhood. On physical examination, the testicular mass (left) was hard, adult fist sized and associated with transparent cystic fluid. Under the impression of testicular tumor, orchiectomy was performed. We report this case with review of literature.

PURPOSE: Anatomic configuration of the ankle joint is useful information during various ankle procedures. This study was prospectively designed to investigate the sagittal inclination pattern of the ankle joint. MATERIALS AND METHODS: Lateral standing ankle radiographs from one-hundred people (age: 17~68, M:F=45:55) and magnetic resonance (MR) sagittal ankle images from twenty-four people (age: 16~65, M:F=14:10) were studied. Post-traumatic, arthritic, or grossly deformed ankles at any reason were excluded. The posterior inclination angle (PIA) of the distal tibia was measured and compared between the lateral and the medial segment. RESULTS: On plain radiographic data, the average PIA of the distal tibia was 6.14 degrees +/-3.56 degrees (range 0 degree to 14 degrees) in the lateral segment and 13.16 degrees +/- 3.05 degrees (range 6 degrees to 22 degrees) in the medial segment. On MR imaging data, the average PIA of the distal tibia was 5.08 degrees +/- 4.26 degrees (range 1 degree to 10 degrees) in the lateral segment and 10.16 degrees +/- 4.87 degrees(range 5 degrees to 17 degrees) in the medial segment. The PIA between two segments was significantly different. CONCLUSION: The sagittal configuration of the medial area ankle joint and the lateral area ankle joint has difference in the degree of posterior inclination and shape of curvature.

PURPOSE: Fragile X syndrome (FXS) is the most common heritable cause of cognitive impairment. FXS is caused by hyperexpansion and hypermethylation of a polymorphic CGG trinucleotide repeat in the 5' untranslated region of the fragile X mental retadation-1(FMR1) gene. Combination of Southern blotting and simple polymerase chain reaction(PCR) amplification of the FMR1 repeat region is commonly used for diagnosis in females. To give a definite diagnosis in a female child suspected of having FXS, we carried out the molecular diagnostic test for FXS using the recently developed Abbott Molecular Fragile X PCR Kit. METHODS: The PCR amplification of the FMR1 repeat region was performed using the Abbott Mdecular Fragile X PCR Kit. The amplified products were analyzed by size-separate analysis on 1.5% agarose gels and by DNA fragment analysis using Gene scan. RESULTS: Agarose gel and Gene scan analyses of PCR products of the FMR1 repeat region showed that the patient had two heterozygous alleles with a normal 30 repeats and full mutation of >200 repeats whereas her mother had two heterozygous alleles with the normal 30 repeats and premutation of 108 repeats, suggesting that the premutation of 108 repeats in her mother may have led to the full mutation of >200 repeats in the patient. CONCLUSION: We diagnosed FXS in a female patient using a simplified molecular diagnostic test. This commercially available diagnostic test for FXS, based on PCR, may be a suitable alternative or complement method to Southern blot analysis and PCR analysis and/or methylation specific(MS)-PCR analysis for the molecular diagnosis of FXS in both males and females.
