BACKGROUND: Moyamoya disease is a chronic cerebrovascular disorders in which stenosis of the major arteries of the circle of Willis at the base of the skull progresses to occlusion. We observed two kinds of collateral pathways from the extracranial to the intracranial arteries. Also we evaluated clinlcal and neuroimaging features of moyamoya disease to give on aid in diagnosis. METHODS: We analysed 17 patients with moyamoya disease through the medical record and neuroimaging (conventional angiography and/or MR angiography) review. Six out of 17 patients were children(< OR =15 years) and the other 11 patients were adults(15 years). There were 8 males and 9 females. RESULTS: In our result, moyamoya disease was more common in the adult. There was bimodal age distribution, so average age of onset in children was 8-year-old and in adult 37-year-old. Common clinical features are seizure (66%), TIA (17%), and psychotic behavior (17%) in childrens and hemorrhages (73%), infarction (18%), seizures (9%) in adults. According to angiographic staging classification of Suzuki et al. (1967), our cases showed distribution of stage I (13%), stage II (8.8%), stage III (65.3%), stage IV (4.3%), stage V (4.3%), stage VI (4.3%). In collateral vessels of moyamoya disease, there were 7 cases of ethmoidal moyamoya, 3 of vault moyamoya and 1 of mixed form. It is interesting that there were five cases of unilateral moyamoya disease and one case had pseudoaneurysm. CONCLUSION: According to our results, we may say that seizures are common in the children and hemorrhages are in the adult. Unilateral moyamoya were mainly occurred in the adult. Ethmoidal collaterals were common among collaterals and stage III had a more cases than others in our neuroimaging data. These clinical and neuroimaging data may help interpretation and diagnosis of moyamoya disease.

We report a case of rare cervical isthmic spondylolisthesis of C6-7 combined occult spinal bifida at C6, and review the radiologic finding, different diagnosis and treatment. A 23-year old female presented nuchal, back pain after traffic accident. Radiologic finding showed the 6th cervical isthmic defect, spondylolisthesis and dysplasia. The patient was conservatively treated about 8 weeks, and 10 months after injury, she was symptom free with full range of motion of cervical spine and she was followed up. Cervical spondylolysis is a very rare condition. This clinical importance is vulnerable to trauma. For whatever reasons, symptomatic patients need to be treated by conservative or surgical option.

Spinal epidural lipomatosis(SEL) is characteristic by abnormal accumulation of unencapsulated fat in the epidural space, which usually occurred as a complication of longterm steroid therapy or Cushing's syndrome and occasionally in obese patients with no other known etiology. This condition, which may result in devastating neurologic complications has also been reported without exogenous steroid intake. Magnetic resonance imaging is the meet helpful diagnostic means and should be used initially. We describe a case of nonsteroid induced symptomatic SEL associated with phenytoin-induced hypothyroidism and obesity. A 27-year-old woman was hospitalized with inability to walk for 2 months ago. She has back pain in her legs associated with radiating pain. She had a history of myoclonic seizure and treated with phenytoin 300 mg for 8 years. On admission, she shows mild hypothyroidism on thyroid function test. Serum phenytoin level was elevated as to 22.1 ug/ml. On cross sectional MRI, the thecal sac has a striking stellate appearance with three rays emanating from a central core. It produces a trifid shape resembling the letter "Y". Correction of underlying endocrine abnormality with weight reduction instead of decompressive laminectomy can reverse the process. In a obese patient with radicular pain or progressive paralysis, SEL may be the etiologic factor involved.

OBJECTIVE: To compare the low frequency (1 Hz) repetitive transcranial magnetic stimulation (rTMS) with high frequency (20 Hz) rTMS on motor functional improvement of the affected upper extremity in subacute stroke patients. METHODS: Forty patients with subacute ischemic stroke participated in this study. The first group received 10 sessions of 20 Hz rTMS at ipsilesional M1 area and the other group received 10 sessions of 1 Hz rTMS at contralesional M1 area. Motor training of the hemiparetic hand was conducted after each rTMS train. All the patients received conventional occupational therapy immediately after each rTMS session. Manual function test (MFT), Fugl-Meyer Assessment scale (FMS), Modified Barthel Index (MBI), Brunnstrom recovery stage, and grip strength were used to assess motor function before, at the end of, and one month after the last session of rTMS. RESULTS: No adverse side effects were reported during the course of the experiment using rTMS. No significant difference in motor function of the affected upper extremity was observed between the two groups before rTMS. Significant improvements in MFT, FMS, MBI, and Brunnstrom stage were observed in the both groups at the end of the last rTMS session and one month later (p<0.05). No significant difference was found between the two groups (p>0.05). CONCLUSION: There was no significant difference in motor function of the affected upper extremity between 1 Hz and 20 Hz rTMS during the subacute period of ischemic stroke. Thus, we cannot conclude which has a greater effect.

BACKGROUND: Although a magnetic resonance imaging (MRI) is highly sensitive for changes associated with ischemic stroke, the detection of an acute ischemic lesion is usually impossible within 6 hours of the stroke onset on a conventional MRI. The perfusion MRI is a new imaging technique for diagnosing acute ischemic stroke. We evaluate the clinical usefulness of the perfusion MRI in predicting the final infarct extent in 18 patients with acute middle cerebral artery (MCA) territory ischemic stroke. METHOD: The perfusion MRI was performed within 6 hours after the stroke onset in all patients with a single-section dynamic contrast-enhanced T2*-weighted imaging in conjunction with a conventional routine MRI and MR angiography. Time-concentration curves and cerebral blood volume (CBV) maps were calculated from the dynamic MR imaging data by using numerical integration techniques. We compared findings of CBV maps with infarction on a follow-up CT or MRI. RESULTS: In 14 of 18 patients, the CBV in the occluded MCA territory were decreased. In the remaining 4 patients with a reversible ischemic neurologic deficit (RIND) or transient ischemic attack (TIA), the CBV were increased in 3 and normal in 1. Out of 14 patients with a decreased CBV, two had focal regions of increased CBV within the affected territory, indicating reperfusion hyperemia. The regions of increased or decreased CBV were eventually converted to infarction on follow-up images in all 14 patients. Out of 4 patients with RIND or TIA, one showed focal infarction in centrum semiovale on a follow-up image. CONCLUSIONS: The perfusion MRI was useful for the assessment of hemodynamic change about cerebral perfusion and may predict the extent of final infarction in acute MCA territory ischemic stroke. These results suggest that the perfusion MRI may play an important role in the diagnosis and management of acute ischemic stroke.

The majority of flexible bronchoscopies are performed under topical anesthesia with lidocaine being the most commonly used agent. Anaphylaxis rarely occurs after local administration of lidocaine, but can be a fatal complication. We experienced a case of unexpected anaphylaxis. A 66-year-old woman was scheduled for flexible bronchoscopy to evaluate a tracheal mass and stenosis. The oral and nasal mucosa were pretreated with lidocaine. About 2~3 minutes later, the patient developed hypotension and we treated for anaphylaxis in the emergency room. Then, we decided to perform rigid bronchoscopy in this patient, under conditions of general anesthesia. A rigid bronchoscopy was performed in this patient, safely and successfully. The tracheal mass was determined to be squamous cell carcinoma.

BACKGROUND: Hyperprolactinemia has been linked with hyperandrogenism and hirsutism in some women. High plasma Dihydroandrosterone and DHA-S levels were reported in patients with hyperprolactinemia and a dissociation of adrenal androgen and cortisol secretion occurs in normal subjects. The mechanism has not been elucidated, but it has been suggested that pituitary factors other than ACTH modulate adrenal androgen synthesis, One candidate hormone is prolactin. Adrenal tissue has been found to possess prolactin receptors and prolactin has been shown to act synergistically with ACTH and lowers the activity of the enzyme 5a-reductase or 3B-hydroxysteroid dehydrogenase (3B-HSD). The aim of this study was to investigate the secretion of adrenal androgen metabolites in patients with idiopathic hyperprolactinemia and prolactinoma and to deterrnine the relationship with prolactin and androgens. METHODS: We measured 24 hour-urinary DHEA, androstenedione, androsterone, pregnenolone, tetrahydrocorticoid and cortisol in 16 normal controls and 5 patients with idiopathic hyperprolac-tinemia (HP) and 12 patients with prolactonoma in the early follicular phase. RESULTS: Urinary DHEA, AD (androsteredione), and androsterone, the metabolites of adrenal androgen, were significantly higher in both patients with idiopathic HP and prolactinoma compared with those in normal controls (p<0.05), whereas they were not different in both disease groups. Urinary pregnenolone levels, early metabolite of adrenal steroid synthesis, were lower in patients. In contrast, urinary tetrahydorcortisol and cortisol were higher in patients compared to controls. There was no difference in DHEA:androsterone ratio between patients and controls. And there were no correlation between prolactin levels and the levels of androgenic metabolites or clinical symptoms. CONCLUSION: Prolactin has a tropic effct on the secretion of androgens and steroids by the adrenal cortex. But prolactin levels were not correlated with androgen levels or clinical symptoms (amenorrhea), and it might have little effect on lowering the activity of 3B-HSD.

Pulmonary hypertension is a frequent complication of chronic obstructive pulmonary disease (COPD) and associated with a worse survival and increased risk of hospitalization for exacerbation of COPD. However, little information exists regarding the potential role of systemic inflammation in pulmonary hypertension of COPD. The purpose of the present study was to investigate the degree of C-reactive protein (CRP) and endothelin-1 (ET-1) levels in COPD patient with and without pulmonary hypertension. The levels of CRP and ET-1 were investigated in 58 COPD patient with pulmonary hypertension and 50 patients without pulmonary hypertension. Pulmonary hypertension was defined as a systolic pulmonary artery pressure (Ppa) > or =35 mmHg assessed by Doppler echocardiography. Plasma CRP and ET-1 levels were significantly higher in patients with pulmonary hypertension than in patients without hypertension. There were significant positive correlations between the plasma ET-1 level and CRP level in the whole study groups. For COPD patients, systolic Ppa correlated significantly with plasma CRP levels and plasma ET-1 levels. These findings support a possibility that CRP and ET-1 correlate to pulmonary hypertension in COPD patients.

OBJECTIVES: Many patients diagnosed with cancer suffer from various psychiatric symptoms such as depression, anxiety and insomnia as well as cancer itself. Patients with cancer are more vulnerable to possible adverse events of psychotropic medications. Although antidepressants are widely used among cancer patients, there is little information about tolerability of antidepressants. This study was conducted to compare tolerability of antidepressants in cancer patients referred for psychiatric consultation. METHODS: The participants were cancer patients who had been referred to psychiatrist for their psychiatric symptoms. We retrospectively analyzed the data of patients diagnosed with cancer from 9 general hospitals in Korea. The discontinuation rate for a 6 months period after treatment initiation for three antidepressants(Escitalopram, Mirtazapine, Paroxetine) were compared. RESULTS: Antidepressants were prescribed for 96.3% of subjects and Escitalopram 150(47.2%), Mirtazapine 92 (28.9%) and Paroxetine 76(23.9%) were prescribed frequently in order There were no significant differences in discontinuation rates among the three antidepressants during the 6 month period after initiation of pharmacotherapy. But there was a difference in discontinuation rates between inpatients versus outpatients(p<0.0001). CONCLUSIONS: In a naturalistic setting for the antidepressant treatment for cancer patients, it seems that there are no differences in discontinuation rates among these three antidepressants. It is therefore essential that such interactions are carefully considered when treating patients of antidepressants who already have cancer.

A 1. 8-year-old intact female Maltese dog was presented because of a history of chronic diarrhea, polyphagia, weight loss, and coprophagia. The patient was severely emaciated and evacuated very moist and four-smelling, yellow feces. Fecal stain with Sudan III revealed numerous lipid droplets. Result of fat absorption test showed aldigestion. A definite diagnosis was made based on trypsin-like immunoreactivity assay in serum which was low enough to be diagnosed as an exocrine pancreatic insufficiency. After pancreatic enzyme supplement with porcine pancreatin powder, the clinical signs were disappeared. This case report documents clinical manifestations, diagnostic tools, treatment and efficiency of oral pancreatic enzyme replacement therapy of exocrine pancreatic insufficiency in a Maltese dog.
