Although the goal of fracture treatment is alive bony union with anatomical reduction, prosthetic replacement is indicated for some complicated femoral neck fracture. However it is not defined until now which one is selected between hemiarthroplasty and total hip replacement for the delayed or complicated femoral neck fracture. In order to get the criteria which one is better for this patient when indicated, we reviewed the result of 39 endoprosthetic and 16 total hip replacement patients at Seoul National University Hospital between June of 1975 to June of 1980. Both methods of endoprosthesis and total hip replacement showed satisfactory results of 72% and 90% respectively. Considering two points of the pain-relief and walking ability, total hip replacement is believed to be far better than endoprosthesis, especially for those patients who are over 50 years of age and have had more active living conditions before fracture.

PURPOSE: To compare the exposure rates of two wrapping materials for hydroxyapatite (HA) ocular implants (Tutoplast(R) vs. vicryl mesh). METHODS: We reviewed the medical records of 137 eyes of 137 patients who had received intraorbital HA implantation from March 1997 to March 2001. RESULTS: We used Tutoplast(R) in 72 patients and vicryl mesh in 65 patients. The mean follow-up period was 22.1 months. Implant exposure developed in four cases of eyes using vicryl mesh. No case of exposure occurred in eyes using Tutoplast(R). The mean period from operation and implant exposure was 3.5 weeks (1.5~5 weeks). CONCLUSIONS: When vicryl mesh was used as the wrapping material for HA intraorbital implant it is advisable to pay more attention to the possible postoperative implant exposure than when Tutoplast(R) was used.

The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of 500 mL of blood within 24 hours. A pan-systolic murmur was found on chest examination. A chest computed tomography showed airspace consolidation in the right upper and middle lobes, with faint bilateral ground glass opacity. Echocardiography revealed mitral valve prolapse and grade IV mitral regurgitation. The patient was diagnosed with sporadic primary mitral valve prolapse. After mitral valve repair surgery, the patient recovered fully.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

PURPOSE: Acute gangrenous cholecystitis (AGC) is a severe advanced form of cholecystitis, and it has a higher morbidity and mortality rate than that that of acute nongangrenous cholecystitis (ANGC). Identifying the CT findings of gangrenous cholecystitis will enable physicians to make an early diagnosis and administer aggressive treatment. METHODS: From January 2005 to October 2007, the CT scans in 277 patients (80 with AGC, 149 with ANGC and 45 with normal gallbladder (NGB)) were retrospectively reviewed by 2 radiologists. We evaluated the findings that included wall thickening (>3mm), distension (transverse diameter > 5cm), gallstones, pericholecystic fluid, pericholecystic inflammation, mural striation, adjacent hepatic enhancement, pericholecystic abscess, an intraluminal membrane, an irregular or absent wall, gas in the wall or lumen, and intraperitoneal fluid. The sensitivity and specificity of the each CT finding for diagnosing AGC were calculated. The dimension and wall thickness of the gallbladder were also measured. RESULTS: The sensitivity, specificity and accuracy of CT for diagnosing AGC were 27%, 94% and 74%, respectively. The findings with the highest specificity for AGC were gas in the wall or lumen (100%), intraluminal membranes (99.5%), pericholecystic abscess (99.5%), an irregular or absent wall (98.5%), adjacent hepatic enhancement (97.9%), intraperitoneal fluid (96.9%), pericholecystitic fluid (95.6%), and mural striation (93.8%). The difference of the mean gallbladder wall thickness between the groups was statistically significant. CONCLUSION: These specific CT findings, including the GB wall thickness, will assist clinicians in making an earlier and more exact diagnosis of gangrenous cholecystitis

Differential surgical procedures have been described on the treatment of patients with obstructing carcinoma of the left colon and rectum, and these vary from classical three stage approach to primary resection and anastomosis using intraoperative colonic irrigation or subtotal colectomy. Staged colonic prcedures are associated with significant morbidity and mortality eventhough its initial easy performance, and many patients, unfit for further surgery, are left with a permanent colostomy. We have already reported the initial results of intraoperative antegrade colonic irrigation for one-stage operation in obstructing left colorectal cancers. In this investigation, we evaluated the results of prospective trials of primary resection and anastomosis using intraoperative colon irrigation and subtotal colectomy in obstructing left colon and rectal carcinomas. During recent five years, 19 cases of obstructing left colon and rectal carcinomas which could not received regular colon preparation due to marked abdominal distension were enrolled to this study. There were 12 men and 7 women, and mean age was 61. 14 of the 19 patients which tumors located below mid-descending colon were subjected to primary resection and anastomosis using intraoperative antegrade colonic irrigation, 4 patients which tumors located above the mid-descending colon were treated with subtotal colectomy, and remaining one patient which tumor located upper rectum was performed subtotal coloectomy because of underlying colonic ischemia. There was no mortality and significant postoperative complications such as anastomotic lealrage, pelvic abscess or intraabdominal sepsis which seemed to be related with anastomotic dehiscence. Therefore, primary resection and anastomosis using intraoperative colonic irrigation or subtotal colectomy depending on tumor locations in cases of obstructing left colon and rectal carcinomas might be useful methods to obtain safe one-stage restorative colorectal resections.

BACKGROUND: Our study aimed to make a comparative analysis of clinical outcomes of arthroscopic decompression for rotator cuff calcific tendinitis by location of calcific deposits and by its size. METHODS: We enrolled a total of 38 patients, comprising 39 affected shoulders, who underwent arthroscopic decompression for calcific tendinitis. As our clinical scores, we evaluated the UCLA, the ASES, and the VAS scores and analyzed them by calcific location, by calcific deposit size, by the presence or absence of calcific remnants, and by whether concomitant cuff repair was performed. RESULTS: The clinical scores of those whose calcific deposit had an area greater than 77.0 mm2 and of those whose calcific deposit had an area smaller than 77.0 mm2 did not significantly differ (p=0.21 in ASES; p=0.19 in UCLA; p=0.17 in VAS). Nor did the clinical scores significantly differ with respect to the location of calcification (p=0.23). Further, the clinical scores did not significantly differ between those who had calcific remnants and those who did not and between those who received additional cuff repair and those who did not. CONCLUSIONS: We found that the clinical outcomes after arthroscopic decompression of calcific tendinitis were not significantly associated with the cuff tendon in which the calcium deposits are found; the location of the calcium deposits in the supraspinatus tendon (if found in this tendon); the size of calcific deposits; the presence of calcific remnants; and concomitant cuff repairs.

Limb-Body Wall complex is a complicated with the essential features of neural-tube defects, body-wall disruption, and limb abnormalities. This complex should be distinguished from other body-wall defects including omphalocele and gastroschisis since the prognosis for limb-body wall is uniformly poor. We have experienced one case of limb-body wall complex in a 22-year-old primigravida, which is presented with a brief review of the literature.
