We report a case of delayed rupture of pseudoaneurysm after operation for meningionma. A 68-year-old female presented with mild headache and hemiparesis. Magnetic resonance imaging showed a cystic mass lesion with a solid component, which was attached to dura in the right frontal area. The mass was totally removed, and diagnosed to transitional type meningioma with histopathological examination. Postoperatively, almost of preoperative symptoms were impoved. About a month later, she developed sudden onset deterioration of mental state and hemiparesis. Computed tomography disclosed a large intracerebral hemorrhage at the site of the tumor bed. Emergency operation was performed. During the evacuation of hematoma, we found a ruptured pseudoaneurysm, and secured it with circumferential wrappig and clipping. The patient recovered well and became ambulatory. In case of delayed intracerebral hematoma at the postoperative site, a possibility of the rupture of pseudoaneurysm should be considered.

BACKGROUND: The emergence of multidrug-resistant strains of Mycobacterium tuberculosis presents a significant challange to the treatment and control of tuberculosis, and there is an urgent need to understand the mechanisms by which strains acquire multidrug resistance. Recent advances in molecular methods for the detection of M. tuberculosis genetic targets have approached the sensitivity of culture Furthermore the prospect of determining resistance in mycobacteria at the nucleic acid level particulary to first-line drugs like rifampin, isoniazid has provided a glimps of the next generation of sensitivity test for M. tuberculosis. Previous studies in RMP resistant M. tuberculosis have shown that mutation in beta subunit of RNA polymerase is main mechanism of resistance. METHOD: In this study, rpoB gene for the ~3 subunit of RNA polymerase from M. tuberculosis of 42 cultured samples (32 were RMP resistant and 10 were sensitive cases) were isolated and characterised the mutations. Direct sequencing data were compared with the results of INNO-LiPA Line Probe Assay (LiPA, Innogenetics, Belgium), commercial RMP resistance detecting kit using reverse hybridization method. RESULTS: All of the RMP resistant samples were revealed the presence of mutation by LiPA. In 22 samples (68.8%) out of 32 RMP resistant cases, the mutation types were confirmed by the positive signal at one of 4 mutation bands in the strip. The most frequent type was R5 (S53 IL) which were 17 cases (77.3%). Results of direct sequencing were identified the exact characteristics of 8 mutations which were not comfirmed by LiPA. S522W type point mutation and 9 base pair deletion at codon 513-515 were new identified mutations for the first time. CONCLUSION: Mutations in rpoB gene is the main mechanism of RMP resistance in M. tuberculosis and LiPA is a very useful diagnostic tool for the early diagnosis of RMP resistance in M. tuberculosis.

OBJECTIVE: In the present study, we evaluate visual outcomes after surgical removal of craniopharyngiomas and analyze the factors that are considered to affect visual outcomes. METHODS: This study includes 30 patients with craniopharyngioma, who underwent surgery in this clinic during the last 10 years. The changes of visual function (visual acuity and field) of the patients were assessed preoperatively and postoperatively, and paired data of this change were compared. Also, the factors that influence on this change were analysed. RESULTS: Among the 21 patients complaining of decreased vision before the operation, 8 patients were improved (38.0%), and 7 patients were worse (33.3%). However, Four out of 9 patients without any preoperative visual symptoms developed worse vision after the operation (44.4%). The average duration of symptom was 17.2 months in the improved group and 23.6 months in the aggravated group. The tumors recurred in only 5 patients after the gross total resection: Four of them showed the aggravation of visual function after surgical removal and 1 had improvement. CONCLUSION: After removal of craniopharyngiomas, the overall rate of vision improvement, no change and aggravation are 26.6%, 36.7% and 36.7%, respectively. Aggravation of postoperative visual function is higher in males, children and patients with a longer duration of symptom and the tumor recurres more frequently in patients who complained of worsened vision after surgical removal.

We report a case of metastatic hemangiopericytoma to the cervical spine. A 55-year-old female having a history of intracranial cavernous hemangiopericytoma, which was found 78 months ago was admitted to our hospital with posterior neck pain and left arm radiating pain. Magnetic resonance image revealed a tumor invading the C6 and C7 vertebral body and compressing the spinal cord. The histopathologic findings were characteristic of hemangiopericytoma. Extracranial metastases of hemangiopericytoma can occur long after the previous treatment in unexpected sites, especially in skeletal system. Bone scintigraphy is an useful tool to detect osseous metastasis, furthermore single negative scan is not sufficient to exclude bone metastasis.

Isaacs' syndrome consists of spontaneously occurring muscle activity of peripheral nerve origins. This syndrome arises in association with/without polyneuropathy and rarely with malignancy. A 63-year-old man was admitted to our hospital due to generalized painful muscle stiffness. He complained of difficulty with standing and with finger exten-sion after grasping. Chvostek's and Trousseau's signs were noticed. Electrolytes, calcium, CK, and LDH were in the normal range. Small cell lung cancer was diagnosed by a needle biopsy. Electrophysiological testing revealed normal nerve conduction studies with the exception of a grossly abnormal EMG. Continuous neuromyotonic discharges with firing rates of 120-200 Hz were seen at rest. The amplitude of the response typically waned with 0.5-1.5 seconds of duration. The discharges persisted throughout sleep, after diazepam injection, and with brachial plexus blockage.Muscle stiffness improved with the administration of oral phenytoin. Under chemotherapy and radiotherapy, tumor remission was partially achieved and neurological symptoms markedly improved.

OBJECTIVES: Essential hyperhidrosis is a common condition characterized by excessive body sweating. Excessive sweating beyond what is necessary to maintain normal body temperature need not be considered pathological unless it interferes with one's occupation and/or life-style. The existing non-operative therapeutic options seldom give sufficient relief or show a transient effect. In this regard, the thoracic sympathectomy may provide a definitive cure. In the past, surgical procedures were highly invasive and caused significant morbidity, but the minimally invasive thoracoscopic procedure provided detailed visualization of sympathetic ganglia and is associated with minimally postoperative morbidity. Nowadays, thoracoscopic transthoracic sympathectomy is accepted as the treatment of choice for essential hyperhidrosis. In palmar hyperhidrosis, however, the level of sympathetic chain to be blocked has been somewhat obscure. It is assumed that the incidence of compensatory hyperhidrosis may closely related to the extent of thoracic sympathectomy. MATERIALS AND METHODS: To compare the results of posterior midline approach with endoscopic sympathectomy, and the results of T2 with T2, 3 sympathectomy or sympathicotomy, we retrospectively studied 62 patients treated for palmar hyperhidrosis between September 1993 and May 2000. We reviewed medical records and recently interviewed the patients by telephone calls. RESULTS: The treatment effect of T2 sympathectomy is no different from T2, 3 sympathectomy. But, the incidence of compensatory hyperhidrosis is less in the T2 sympathectomy group than the T2, 3 sympathectomy group. CONCLUSION: Thoracoscopic sympathectomy is considered a simple, safe, and effective method for treating palmar hyperhidrosis, with a shorter operation time, fewer hospital days, and a better cosmetic result, as compared with the open approaches. However, sympathicotomy seems to provide the advantages of a limited extent of denervation and the resultant decrease of compensatory hyperhidrosis compared to sympathectomy.

OBJECTIVE: To find the characteristics of stroke in colorectal cancer patients. METHOD: We retrospectively analyzed 32 patients of stroke in colorectal cancer who were operated from January 2001 to December 2002 by reviewing their charts and brain CTs or MRIs. The type, risk factor, localization and origin of stroke and the stage of colorectal cancer were analyzed. RESULTS: The mean age was 69.2 years. TNM stage II (41%) was the most common. Twenty-three cases were ischemic stroke, four were hemorrhagic stroke and the others were unidentified. Diabetes (63%), hypertension (53%), cardiac disease (19%), and family history of stroke (9%) were observed in patients. The main cause of ischemic stroke was arterial thrombosis, and lacunar and middle cerebral infarction were more common in ischemic stroke. CONCLUSION: Several common risk factors between colorectal cancer and stroke were observed, and these risk factors are associated with the atherosclerosis of cerebral vascular system. To reduce the incidence of cerebrovascular disease and colorectal cancer, we may need to control those risk factors.

BACKGROUND/AIMS: Pain is one of the most troublesome symptoms of pancreatitis. Transdermal fentanyl patches (TFPs) are long-acting analgesics with a reduced risk of dependency. This prospective study evaluated the effect of TFPs on sphincter of Oddi (SO) motility for the management of pain in pancreatitis. METHODS: SO manometry (SOM) was performed using triple-lumen catheters anterogradely inserted through the percutaneous transhepatic route during cholangioscopy in 16 patients. The basal pressure, amplitude, and frequency of the SO were assessed before and after applying a TFP at 24 hour at doses of 25 and 12.5microgram/hr, respectively. RESULTS: Two of 16 patients receiving a 25microgram/hr. TFP were excluded because of adverse side effects (headache and/or nausea). The mean basal pressure, amplitude, and frequency of SOM did not change significantly in the 25microgram/hr TFP group (n=4 patients). Parameters of SO function also did not significantly change in the 12.5microgram/hr TFP group (n=11 patients). CONCLUSIONS: TFPs below a dose of 25microgram/hr may not affect the motility of the SO. Administration of TFPs at lower dosages seems to be a safe analgesic treatment for the pain control of patients with pancreatitis without affecting the function of the SO.

Background:
Patient-centered management is becoming increasingly important in gout, but there are limited studies exploring patients' perspectives and preferences. We aimed to investigate patients' perspectives and preferences regarding gout and gout management, and their impacts on adherence to urate lowering therapy (ULT).
Methods:
A paper-based survey was performed in patients with gout seen at the rheumatology outpatient clinics of 16 tertiary hospitals. The survey included questions regarding demographics, comorbidities, gout attacks, current treatment and adherence, and patients' perspectives and preferences regarding gout and gout management. Multivariate regression analysis was performed to determine the factors associated with ULT adherence.
Results:
Of 809 surveyed patients with gout, 755 (94.5%) were using ULT. Among those using ULT, 89.1% had ≥ 80% adherence to ULT. Majority of the patients knew management strategies to some extent (94.8%), perceived gout as a life-long disease (91.2%), and were making efforts toward practicing at least one lifestyle modification (89.2%). Most patients (71.9%) obtained information about gout management during their clinic visits.Approximately half of the patients (53.6%) preferred managing their disease with both ULT and lifestyle modification, 28.4% preferred ULT only, and 17.4% preferred lifestyle modification only. Adherence was better in patients with older age (odds ratio [OR], 1.03), those with better knowledge of gout management strategies (OR, 3.56), and those who had preference for ULT (OR, 2.07).
Conclusion
Patients' perspectives and management preferences had high impacts on adherence to ULT in gout. Consideration of patients' perspectives and preferences is important for achieving the desired clinical outcome in gout.
