Thirty one free vascularized fibula bone grafts were performed for treatment of osteonecrosis of the femoral head in 26 patients, 24 men and 2 women aged from 16 to 48(mean:32 years). Twenty one patients had unilateral disease. Five patients had bilateral disease underwent staged bilateral free vascularized fibula grafts three months apart. Associated etiological factors included alcohol(9 patients), steroid(7 patients), and trauma(one patient). The condition was considered idiopathic in the remaining 9 patients. Radiologic staging by Ficat included stage 1 in one hip, stage II in 15 hips, stage III in 14 hips, and stage IV in one hip. A skin island flap was used for monitoring purpose for the grafted fibula. One monitoring, flap was necrotized due to vascular occlusion but the fibula bone graft was left in place to use as a nonvascularized bone graft. Average follow-up period was 21 months in 31 hips. Pain was relieved in 28 hips(93.3 percent) and aggravated in 2 hips(6.7 per cent). On radiographic evaluation, 26 hips(86.7 per cent) demonstrated excellent preservation of the femoral head contour. Progressive collapse of the femoral head (greater than 1-2 mm) occurred in 2 hips, i mm depression in one hip with stage III and 2 mm collapse in one hip with stage IV. In conclusion, the free vascularized fibula bone graft is an excellent treatment modality for preserving the femoral head and relieving symptoms in cases of the osteonecrosis of the femoral head.

PURPOSE: Diagnosis of a hemodynamically significant patent ductus arteriosus (PDA) that should be treated is difficult to determine by clinical and echocardiographic examination. The purpose of this study is to clarify the usefulness of diastolic flow velocity (DFV) of the left pulmonary artery (LPA) determined by echocardiography in the assessment of significant PDA in preterm infants. METHODS: Clinical and echocardiographic findings, including DFV in LPA, of PDA were evaluated at 24 hours, 48-72 hours of age and after indomethacin treatment in thirty-nine infants ranging from 25 to 34 gestational weeks of age. DFVs of the study group (N=13) with significant PDA were compared with those of healthy control group (N=26) without significant PDA. RESULTS: DFVs in healthy preterm infants were high in the first few days and were significantly decreased after spontaneous ductal closure. DFVs in preterm infants with significant PDA who underwent indomethacin treatment were significantly higher than that of healthy control infants. After indomethacin treatment, DFVs in this study group remained high with continuing significant PDA and markedly decreased with disappearance of significant PDA. Until ductus arteriosus closed, DFVs showed a significant correlation with the magnitudes of ductal shunt. A cutoff value for DFV of 30 cm/sec showed a sensitivity of 77% and a specificity of 92% as a predictor of significnat PDA in preterm infants. CONCLUSION: Measurement of DFV in LPA by echocardiography is a useful method for assessing the significnat PDA which may require treatment in preterm infants.

Cushing's syndrome associated with nodular adrenal glands will be divided into four main categories: adrenal adenoma, adrenal carcinoma, primary pigmented nodular adrenal dysplasia (PPNAD) and macronodular adrenal hyperplasia(MAH). The term macronodular adrenal hyperplasia is restricted to the presence of multiple nodules visible to the naked eye, ranging in size from 0.5 to 7.0 cm. We report a case of Cushings syndrome caused by bilateral macronodular adrenal hyperplasia (MAH). A 45-year-old man presented with Cushingoid features, hypertension and diabetes mellitus. Urine free cortisol was 449.9 mmol/day(27-276) and were not suppressed after administration of low-dose and high-dose dexamethasone. Plasma ACTH was very low(1.87 pmol/L(18)) and was not stimulated by administration of ovine CRH. In abdominal CT, both adrenal glands were markedly enlarged and nodular in appearance. Pituitary MRI showed no abnormal finding. Bilateral adrenalectomy was done. Histologic examination revealed multiple nodules and internodular hyperplasia. This case and other reports suggested that because of variable biochemical, radiologic and pathologic findings, macronodular adrenal hyperplasia represents a heterogeneous group of patients with varying degrees of adrenal autonomy.

Background: Whole body scan using 131-iodine is performed to detect local recurrence or metastasis after thyroidectorny in differenciated thyroid cancer patients. The sensitivity of this procedure is related to the dose of radiopharmaceutical administered. It was reported that 131I posttreatment whole body scan demonstrate foci of tracer uptake not previously observed in diagnostic scan in 10~30% of cases. Posttreatment scans were most likely to reveal new foci in young patients(<45) and patients who had previously received radioactive iodine therapy. Method: We observed the frequency of discordant posttreatment scans and analysed the clicnical significance in 33 differenciated thyroid cancer patients who were admitted for radioiodine ablation from June, 1995 to April, 1996. Results: In 7 cases(21.2%), post treatment scan demonstrated cme or more foci of uptake and revealed less sites of uptake than diagnostic scan in 3 cases(9.1%). In one case with elevated thyroglobulin level and negative diagnostic scan, post treatment scan revealed new uptake sites with thyroid bed and cervical 1ymph node. The sites of discordant uptake were cervical lymph nodes in 4 cases and rnediastinal lymph node in one case, lung in one case, thyroid bed and cervical lymph nodes in one case, 3 cases of 7 pts(43%), demonstrated ane or more foci of uptake in post treatment scan, had history of previous radioiodine treatent. Conclusion: Post treatment scan confirmed uptake into remnant and metaststic tissues identified on the corresponding low dose diagnostic scans. Scanning after high dose radioiodine treatment frequently demonstrated one or more foci of uptake, especially in patients with previous radioiodine treatment, which were not visualized on the diagnostic low dose scan. Treatment scan may be useful for detection of remnant tissue or metastatic lesion in patients with elevated thyroglobulin and negative diagnostic scan.

The cannabinoid (CB2) receptor type 2 has been proposed to prevent the degeneration of dopamine neurons in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated mice. However, the mechanisms underlying CB2 receptor-mediated neuroprotection in MPTP mice have not been elucidated. The mechanisms underlying CB2 receptor-mediated neuroprotection of dopamine neurons in the substantia nigra (SN) were evaluated in the MPTP mouse model of Parkinson's disease (PD) by immunohistochemical staining (tyrosine hydroxylase, macrophage Ag complex-1, glial fibrillary acidic protein, myeloperoxidase (MPO), and CD3 and CD68), real-time PCR and a fluorescein isothiocyanate-labeled albumin assay. Treatment with the selective CB2 receptor agonist JWH-133 (10 μg kg⁻¹, intraperitoneal (i.p.)) prevented MPTP-induced degeneration of dopamine neurons in the SN and of their fibers in the striatum. This JWH-133-mediated neuroprotection was associated with the suppression of blood-brain barrier (BBB) damage, astroglial MPO expression, infiltration of peripheral immune cells and production of inducible nitric oxide synthase, proinflammatory cytokines and chemokines by activated microglia. The effects of JWH-133 were mimicked by the non-selective cannabinoid receptor WIN55,212 (10 μg kg⁻¹, i.p.). The observed neuroprotection and inhibition of glial-mediated neurotoxic events were reversed upon treatment with the selective CB2 receptor antagonist AM630, confirming the involvement of the CB2 receptor. Our results suggest that targeting the cannabinoid system may be beneficial for the treatment of neurodegenerative diseases, such as PD, that are associated with glial activation, BBB disruption and peripheral immune cell infiltration.

BACKGROUND/AIMS: Common bile duct stones are the most common among bile duct diseases. In the past, common bile duct stones were considered a surgically operable disease, but is now considered a medical disease due to the advancement of endoscopy and endoscopic techniques. The aim of this study was to determine the results of endoscopic treatment of common bile duct stones. METHODS: Removal of primary or secondary common bile duct stones were attempted by peroral or percutaneous endoscopy. The common bile duct stones were diagnosed by ultrasonography or cholangiography. As a primary approach route, the peroral transpapillary endoscopic approach was tried. On the other hand, percutaneous common bile duct stone removal was attempted if the patient already had a percutaneous route, peroral transpapillary approaches failed, or if conditions for endoscopy were unfavorable. RESULTS: The study subjects consisted of 196 patients; 96 males and 100 females. The mean age was 61.8 years. A total of 272 endoscopic stone removal were attempted in 196 patients. Of the 272, peroral approaches were conducted 241 times for 183 patients, and percutaneous approaches were performed 31 times for 12 patients. The success rate of the first treatment modality to remove the common bile duct stones was 90.3% (176/195). The overall success rate of endoscopic common bile duct stones removal was 100%. CONCLUSIONS: In all patients, the common bile duct stones were removed successfully by endoscopy, and thus supporting the shift of recognizing common bile duct stones as a medical rather than surgical discase.
