Various methods for the treatment of fracture of the femur neck including total hip arthroplasty have been developed and performed, but it is still called the ""unsolved fracture"" in certain situations. The role of bipolar hemiarthroplasty as primary treatment of fracture of the femur neck, however, continues to be controversial. The authors reviewed and analysed 38 cases of cementless bipolar hemiarthroplasty in patients between the ages of 51 and 69 at the Department of Orthopaedic Surgery, Chosun University, during the period from January, 1989 to December, 1994. The purposes of the study were to analyse the clinical and radiological results and to detect the motions of bipolar cup. At the average 38 months follow up, 31 (81.6%) of the patients were satisfied by Lunceford methods. But, 24 (63.2%) of the patients suffered from inguinal area pain and discomfort while they resumed their normal Korean life-styles. As time elapsed, the amount of the outer bearing motion was more than that of the inner bearing motion. the acetabular erosion were present in 2 patients.

Pseudomonas aeruginosa is the most common and the most severe Gram-negative corneal pathogen. Pseudomonas keratitis often arises from the use of a contaminated fluorescein solution or from contaminated medications used either to examine or to treat a corneal abrasion or injury. Pseudomonas keratitis is an acute rapidly progressive corneal ulcer with greenish pus and hypopyon. A 49 year old Korean woman was found to have pseudomonas keratitis whose clinical features. were different from the classic pattern of pseudomonas keratitis.

Laparoscopic cholecystectomy (LC) is considered as the gold standard operation for the removal of a nonmalignant, diseased gallbladder. With the increasing number of LCs, a number of gallbladder carcinomas have been unexpectedly found either during or following this procedure. The removal of unexpected gallbladder carcinomas by LC can cause also a new complication, port site metastasis (PSM), which is developed by the implantation of tumor cells into the abdominal wall at the port site. We report a rare case of PSM of gallbladder carcinoma which was unsuspected at the time of LC. A 65-year-old man underwent LC at another hospital for calculous cholecystitis. The histologic examination revealed an adenocarcinoma of the gallbladder infiltrating the muscle wall. Despite the surgeon's advice, the patient refused any additional treatment. Ten months after surgery, he visited our hospital because of a painful and palpable subcutaneous mass at the scar of the periumbilical trocar incision. The mass was biopsed and histological examination confirmed metastasis from the gallbladder carcinoma.

Choroid plexus papilloma is a very rare disease in children. The manifestations of the disease differ according to the tumor size and the location. Increased CSF production by the tumor, hydrocephalus and symptoms of increased ICP are the main symptoms. The first line of treatment is surgical excision, but sometimes excision itself is very difficult due to the site and the size of the mass. Adjunctive radiation therapy or chemotherapy is not recommended. Since gross total resection without adjunctive therapy offers highest likelihood of success. Significant prognostic factors are sex, age, time of diagnosis, the duration between the appearance of symptoms and diagnosis, tumor volume, tumor site and the extent of surgery. We report a case of choroid plexus papilloma, in a child with anorexia and failure to thrive.

BACKGROUND: The aim of this study was to investigate the development of neuropathic pain by radiofrequency thermocoagulation on a rat infraorbital nerve (IoN). METHODS: Male Sprague-Dawley rats (n = 35) were divided into three groups, consisting of the S, T and sham operation. In the experimental groups, rats were thermocoagulated by subjecting them to 70oC for 60 sec (S group, n = 12) or 20 sec (T group, n = 11) on IoN. In the control group (sham operation, n = 12), IoN was not thermocoagulated. The ipsilateral grooming count and escape threshold by von Frey filament (mechanical allodynia) was measured at 1, 3, 5, 7, 9, 11, 13 postoperative days. After two weeks, a 5% formalin solution was injected into the rat upper lips and grooming time was measured for 45 minutes. RESULTS: Grooming count and mechanical allodynia significantly increased in the thermocoalgulation groups (S and T groups) compared to control group (sham operation) for the postoperative days. Nerve injury by radiofrequency thermocoagulation enhanced the grooming time after formalin injection in the rat upper lips. CONCLUSIONS: These results lend support to the hypothesis that thermal injury using radiofrequency thermocoagulation can induce neuropathic pain in rat IoN and this type of nerve injury increases the responsiveness of chemical nocieptive stimuli.

We have experienced a case of aortic dissecting aneurysm in pregnant woman. She felt initially severe chest pain which was radiated to the neck on the 3days before delivery. Thereafter dyspnea and generalized edema were developed for 1 month after delivery. She was diagnosed as aortic dissectLn, Debakey type-II. During cardiopulmonary bypass, the selective cerebral perfusion was done through the right and left commom carotid arteries. Aortic replacement with Hemashield vascular graft and reimplantation of innominate artery, resuspension of aortic valve, repair of intimal tear were performed. The postoperative course was uneventful.

The radial artery as a graft for myocardial revascularization was introduced by Carpentier et al. in the early 1970s. Mid-term results were unfortunately discouraging, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Sejong General Hospital. Left internal mammary artery was concomitantly used as a pedicled graft in 34 patients. Fifteen patients(42%) had a complete arterial graft revascularization. A total of 123 distal anastomoses were performed(average 3.4 per patient), including 36 left internal mammary artery grafts(two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were performed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex(n=38), diagonal( n=18), right coronary(n=6), and left anterior descending coronary artery(n=2). The percentage of radial artery graft anastomoses(64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures : coronary endarterectomy(14), coronary artery patch angioplasty(4), mitral valve repair(1), and repair of ventricular septal rupture(1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand after removal of the radial artery. Only 1 patient required reexploration of the arm, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiographic controls were obtained in 11 patients(31%) postoperative 79 to 210 days(mean 126 days). The patency rate were as follows : left internal mammary artery(100%), saphenous vein(100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to dertermine whether wider application is warranted.

Pulmonary arteriovenous fistula is a congenital vascular malformation in lung resulting from abnormal capillary development and the exact etiology is not well known but it may occur with or without hereditary hemorrhagic telangiectasia. Hereditary hemorrhagic telangiectasia (L-IHT) or Rendu-Osler-Weber disease is an autosomal dominant vascular disorder which associates epistaxis, mucocutaneous and visceral telangicetases, and recurrent hemorrhage with chronic anemia and visceral shuntings. Recently we experienced a case of the pulmonary arteriovenous fistula in a 23 year old woman with a family history of this disease, which was confirmed by pulmonary angiography.

Hemolytic uremic syndrome (HUS) is characterized clinically by classic triad of microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. The illness is uncommon and various agents have been associated with HUS, such as infectious, genetic, environmental and phamacological factor. We experienced a case of hemolytic uremic syndrome in a eighty-year old man with a evidence for recent Epstein-barr virus infection. He developed hemolytic anemia, thrombocytopenia, hypertension and azotemia. His renal dysfunction was recovered by hemodialysis, plasmapheresis, warfarin and dypiridamole. We present this case with a review of the literature.
