Ever since the unrelenting efforts of Yasuda to Piezoelectricity, its been one of the hot areas in orthopaedic fields to file up experimental and clinical data concerning treatment of nonunion, delayed union and pseudarthrosis. Clinical use of this theory is the result of a systemic thirty-year investigation of bioelectrical phenomina in the skeletal system and of their role in regulating cellular elements. Since Friedenberys clinical application of Semi-invasive direct current stimulation to nonunion of medial malleolus of tibia, Brighton and Bassett made progress in this field with high success rate. In 1985, Non-invasive capacitive coupled electrical field was developed and used clinically by Brighton. We also developed a model of capacitive coupled electrical field system and made clinical application to nonunion of tibia with successful result.

OBJECTIVE: The operative indications on cerebellar hemorrhage have been controversial especially when the patient condition is grave. Therefore we investigated whether it can be justifiable if we perform the surgery in poor clinical grade. METHODS: Clinical records and computerized tomography(CT) films of the 89 patients, who were undergone hospital treatment due to spontaneous cerebellar hemorrhage between May 1997 and May 2004, were retrospectively researched. RESULTS: The study population consisted of 36 males and 53 female patients. The mean age was 65years (range 23~89). As a result of treatment, the patients, whose Glasgow coma scale(GCS) score were higher, showed better outcomes (p=0.001). 13 patients (14.6%) were below 5 in GCS score and 10 patients of these were operated. Among 10 patients, 4 patients (40%) showed good outcome and 5 patients (50%) had been dead. 3 patients (60%) of these dead patients had the findings of intraventricular hemorrhage, fourth ventricular obliteration and hydrocephalus in CT scan. CONCLUSION: This study suggests that operation may be justifiable in clinically poor grade patient with spontaneous intra cerebellar hemorrhage.

Actinomycosis is a chronic suppurative and granulomatous disease caused by Actinomyces species and characterized by sulfur granule formation. Depending on the site of primary infection, it is generally classified as cervicofacial, thoracic and abdominal type. Abdominal actinomycosis is often difficult to diagnose before operation because of low frequency and no characteristic clinical features of the disease. As it progresses chronically, it can be misdiagnosed such as cancer, inflammatory bowel disease or other abscess. The diagnosis is usually based on histologic demonstration of sulfur granules in pus or surgically resected specimen. In vast majority of cases, treatment has consisted of long-term antibiotic therapy coupled with surgical resection. We experienced a case of colonic actinomycosis initially diagnosed as Dieulafoy's ulcer and confirmed by colonoscopic biopsy. Treatment with intravenous penicillin for 4 weeks was successful independently, and we report this case with a brief review of literatures.

Human tails or caudal cutaneous appendages are rare congenital anomalies with lesions usually arising from the midline of the lumbosacrococcygeal area. There have been only around 70 cases reported in literature. A 4-month-old male infant born as the 1st child of a dizygotic twin was presented with a penis-shaped mass of 4-cm in the coccygeal area. The mass was entirely covered by skin without any skin defect and was connected to the midline skin of the posterior coccygeal area by a stalk. Magnetic resonance images showed fat density of the mass without any demonstrable communication with the spinal canal nor any underlying central nervous system anomalies. The patient underwent a simple surgical excision of the mass without residual effects and complications. Histopathologic examination of the mass revealed lobules of mature adipose tissue, fibromuscular soft tissue, small vessels and nerves with normal hair follicles on the skin.

Intracranial dermoid cyst is a rare congenital disease originating in the embryo. Intracranial dermoid cysts are usually detected before five years of age; however, asymptomatic cysts have been discovered after the third decade of life through various complications. Sometimes, there are neurologic symptoms caused by a cystic mass effect and if there is a dermoid sinus, purulent infections can occur. Early diagnosis is important and as such, CT or MR imaging for recognition of the location, size, and characteristics of the cysts are recommended before surgical resection. Extradural dermoid cysts with an intact occipital dermoid sinus are a rare event. We report a case of intracranial dermoid cyst associated with scalp abscess. In this case, a three-year-old boy was presented with scalp abscess and we performed MR imaging, which revealed a cystic region. The prognosis after resection operation was good without any complication.

To evaluate effect of coronary collateral circulation on left ventricular function in patients with acute myocardial infarction, global ejection fraction(EF), left ventricular end distolic pressure(LVEDP), peak creatine kinase(CK) level and regional wall motion were analysed and compared in 30 patients with acute myocardial infarction according to grade of coronary collateral circulation. Patients with total or near total(above 95% of diameter) occlsion of left anterior descending coronary artery without significant lesion in right coronary artery or left circumflex artery were selected and divided into 3 groups according to the degree of collateral circulation on coronary angiography, to be compared by the index of ejection fraction, peak creatine kinase level, left ventricular and diastolic pressure and regional wall motion. The result are as following : 1) There were no statistically significant differences in ejection fraction, peak creatine kinase level, left ventricualr and diastolic pressure among the groups. 2) Regional wall motion of infarct related area of G2+3 group(adequate collateral) were better than that of G0(no collateral) group(p<0.05). Therefore, adequate coronary collateral circulation in acute myocardial infarction is thought to have beneficial effect on left ventricular function especially in regional wall motion of infarct related area.

A 56 year old female was admitted because of the right upper quadrant mass for 4 days. She complained of intermittent colicky RUQ pain, fever and chills. So diagnostic procedures was performed: Blood chemistry testings. Ultrasonography. Barium enema, Liver scan, Hepatobiliary scan, ERCP and Abdomen CT, which diagnosed as gall bladder carcinoma. So explolaparotomy was performed and gross operative finding was gall bladder carcinoma with metastatic lymph node and cystic duct stone. So cholecystectomy, hemigastrectomy and anterior segmentectomy of right liver was done. But the biopsy result was cystic duct stone, cholecystitis and gall bladder empyema.
