Free vascularized tissue transfer to preserve upper extremity amputation level is uncommon but very useful procedure. To cover the below-elbow amputee stump and restore the function of the elbow, we have used a free flap as a spare part concept from the contralateral hand which was so severely damaged that amputation was inevitable.

Seven patients having midline granuloma received local irradiation from March 1983 to June 1986. Clinically, all of the 7 patients had pansinusitis with necrotic destruction of the involved sites and one case revealed colonic lesion. Each of the patients received a tumor dose of 4,000 ~ 5,000 cGy/5~6wks to the upper aerodingestive tract using a 6-MV linear accelerator. Complete and partial remission occurred in 3 patients each, and in one case, the disease progressed despite of the irradiation.

BACKGROUND: Methotrexate (MTX) is an antifolate antagonist that is widely used for treating various malignancies and non-malignant diseases. MTX levels should be monitored when used in high concentration to determine when to start leucovorin rescue. In this study, we evaluated the analytical performance of the EMIT Methotrexate Assay on a 200FR NEO Chemistry Analyzer (Toshiba Medical System Co., Japan) and compared it with Viva-E Drug Testing System (Siemens Healthcare, Germany). METHODS: According to the Clinical Laboratory and Standards Institute (CLSI) Evaluation Protocol (EP) 5-A2, three concentrations of the Liquichek Therapeutic Drug Monitoring Control (Bio-Rad Laboratories, USA) were analyzed twice a day for 20 days to monitor assay precision. The 200FR NEO and Viva-E instruments were compared using 40 patients' sera, according to CLSI EP9-A2. The linearity and carry-over rate were also evaluated. RESULTS: Between-run CVs for low-, medium-, and high-level controls were 4.9%, 0.9%, and 2.0%, respectively, whereas between-day CVs for low-, medium-, and high-level controls were 8.1%, 1.3%, and 3.5%, respectively. In the linearity test, the coefficient of determination (R2) was 0.98 (0.06-1.92 micromol/L). In the comparison study, R2 was 0.955, showing good correlation between the 200FR NEO and Viva-E instruments. The carry-over rate was 0.9%. CONCLUSIONS: The EMIT assay showed good precision, linearity, and carry-over rate on the Toshiba 200FR. An excellent correlation was observed when comparing results obtained using the Toshiba and Viva-E instruments. In conclusion, the Syva EMIT MTX assay can be readily used for MTX monitoring on the Toshiba 200FR NEO.

Spondylolysis, also known as stress injury of pars interarticularis, is a common cause of back pain in athletes, particularly children and young adults. Repeated minor traumas during flexion and extension of the spine are thought to result in bony failure due to excessive bone resorption. These lesions are common in the low back, with the majority found at the L5 vertebra. In the majority of cases of spondylolysis, non-operative treatments are recommended, such as NSAIDs, physiotherapy and bracing. Only if symptoms do not respond to conservative treatments should surgical intervention be considered. Recently, pars interarticularis injections for diagnostic and therapeutic purposes have been found to allow significant pain relief from spondylolysis for long periods. Here, the case of a 57-year-old man with spondylolysis, who suffered from back pain, which was not relieved by an epidural steroid injection, but in whom pars interarticularis injections of local anesthetic and steroid induced complete transient pain relief, following by moderate long-term relief, is presented.

This report describes the perioperative management of an adrenergic crisis and intraoperative pulmonary edema occurring during planned surgery for pheochromocytoma. We experienced the anesthetic management of a 45-year-old male patient with pheochromocytoma on the extra-adrenal retroperitoneum. The patient had been treated with prazosin for only 1 week before surgery. After inducing anesthesia with intravenous remifentanil, thiopental sodium, and rocuronium, anesthesia was maintained with nitrous oxide, oxygen, and isoflurane administration. The blood pressure was poorly controlled with sodium nitroprusside, esmolol, and remifentanil after manipulating the tumor. Pulmonary edema occurred intraoperatively but subsided with positive end expiratory pressure and the use of diuretics and morphine. After removing the tumor, the blood pressure was well controlled using a colloid solution, Hartman's solution, and dopamine administration. This complication occurred because of inadequate preoperative preparation. We reported this case of surgery for the removal of a pheochromocytoma with a review of the relevant literature.

Recurrent ectopic pregnancy of cesarean scar is very rare and its therapeutic management is still not established. We reported the first case of recurrent cesarean scar pregnancy that was successfully treated with concomitant intra-gestational sac methotrexate-potassium chloride injection and systemic methotrexate injection. This case study provides physicians with a safe and effective minimally invasive treatment option for recurrent cesarean scar pregnancy.

PURPOSE: Chronic administration of anticonvulsants for children with epilepsy may cause multiple abnormalities in bone metabolism. The aim of this study was to evaluate the effects of anticonvulsants on bone mineral density(BMD) in children with epilepsy. METHODS: Seventy patients with epilepsy were enrolled in this study. All subjects had taken anticonvulsants for at least 1 year or more. Subjects were classified into three groups according to age(5-7 yrs, 8-11 yrs, >12 yrs). BMD was measured by Dual-energy X-ray Absorptiometry(DXA) on the lumbar spine and whole body. Statistical analysis for BMD of anticonvulsants-treated subjects were compared to results with the published data. RESULTS: BMD was significantly decreased in the anticonvulsants-treated group as compared with the control group of all age groups(P<0.05). But BMD among groups according to anticonvulsants was not significantly different(P>0.05). CONCLUSION: Because chronic administration of anticonvulsants for growing children leads to a decrease in BMD, early detection and management of abnormal BMD is important in monitoring of children with epilepsy.

OBJECTIVE: Gamma knife radiosurgery (GKRS) is the least invasive surgical option for patients with trigeminal neuralgia (TN). However, the indications and long term outcomes of GKRS are still controversial. Additionally, a series with uniform long-term follow-up data for all patients has been lacking. In the present study, the authors analyzed long-term outcomes in a series of patients with TN who underwent a single GKRS treatment followed by a minimum follow-up of 60 months. METHODS: From 1994 to 2009, 40 consecutive patients with typical, intractable TN received GKRS. Among these, 22 patients were followed for >60 months. The mean maximum radiation dose was 77.1 Gy (65.2-83.6 Gy), and the 4 mm collimator was used to target the radiation to the root entry zone. RESULTS: The mean age was 61.5 years (25-84 years). The mean follow-up period was 92.2 months (60-144 months). According to the pain intensity scale in the last follow-up, 6 cases were grades I-II (pain-free with or without medication; 27.3%) and 7 cases were grade IV-V (<50% pain relief with medication or no pain relief; 31.8%). There was 1 case (facial dysesthesia) with post-operative complications (4.54%). CONCLUSION: The long-term results of GKRS for TN are not as satisfactory as those of microvascular decompression and other conventional modalities, but GKRS is a safe, effective and minimally invasive technique which might be considered a first-line therapy for a limited group of patients for whom a more invasive kind of treatment is unsuitable.
