We assessed the accuracy of clinical evaluation, arthrography and arthroscopy in the diagnosis of meniscal lesions in ninty knees in which arthrotomy was performed for disabling symptoms after evaluation by these three methods. At surgery, ninty-two menisci were removed, of which seventy-two were abnormal and twenty were normal. In these ninty-two menisci, correct diagnostic rate was made clinically 78%, arthrographically 70% and arthroscopically 86%. Arthrographic diagnosis was least accurate for lesions of the lateral meniscus and arthroscopic diagnosis was least accurate for lesions of the posterior horn of the medial meniscus and peripheral lesions. Based on this study, it was concluded that both the arthrography and arthroscopy are valuable technique for diagnosis of meniscal lesions.

BACKGROUND: Quinidine appeared to increase serum digoxin levels when given with quinidine. Therefore elevated serum digoxin concentrations and clinical toxicity have been reported in patient receiving quinidine. Currently, Bayesian method which estimates the most probable parameters of the drug for each patient from population parameters data is useful approach for adjusting digoxin dosage. To increase the accuracy of Bayesian method, it is desirable to use population parameters of Korean. Therefore we evaluated the effect of quinidine on digoxin clearance in Korea. METHOD: Patient's records from 19 adult cardiac disease without CHF having normal renal and liver function from Seoul National University of Hospital respectively wre evaluated. Digoxin pharmacokinetic parameters, CL and Vd, were obtained from serum concentration of digoxin of single and combined therapy at each steady-state by using bayesian method. RESULTS: This study show that quinidine reduced the total body clearance of digoxin from 2.39+/-0.17 to 1.51+/-0.08ml/min/kg(p<0.05) and reduced the digoxin volume of distribution from 8.57+/-0.29 to 4.98+/-0.19L/kg(p<0.05). This results show that digoxin dosage reduced to 40-50% in Korean, if quinidine therapy is initiated.

Therapeutic irradiation may produce a variety of adverse side effects on the central and the peripheral nervous systems. These adverse effects are divided into two main groups; transient and permanent. Four major clinical syndromes have been described in relation to permanent radiation injury of the nervous system: encephalopathy, cranial neuropathy, myelopathy, and peripheral neuropathy. Among them, delayed encephalopathy represents the major hazard in CNS irradiation. The characteristic MR imaging pattern of radiation induced delayed necrotizing leukoencephalopathy is symmetric, high-signal foci on T2WI in the periventricular white matter. We report a case of suspected post-irradiation leukoencephalopathy showed progressive mental change, quadriparesis, and urinary incontinence with characteristic MR findings who had taken therapeutic irradiation 12 months ago.

A case of intraneural ganglion, 5cm×2cm×1.5cm, which was located between the funiculi of the common peroneal nerve was excised completely under the operative microscope. There was no communication with adjacent bursa or joint.

BACKGROUND & OBJECTIVES: There are few reports of affecting factors of the longterm prognosis after acute ischemic stroke. The aim of this prospective study was to determine which variables, of those easily measurable during the first 24 hours after stroke onset, would be predictors of longterm outcome. METHOD: Ninety-eight patients with an acute ischemic stroke were evaluated within 24 hours after symptom onset. The following potential affecting factors of outcome were prospectively collected : demographic datas, socioeconomic factors, risk factors of cerebrovascular accidents, clinical f indings as measured by the National Institute of Health (NIH) scale, laboratory findings and premorbid varibles rated according to modified Rankin score (mRS). We evaluated the outcome, assessed with mRS as good (mRS 3 or less) and poor (mRS 4, 5 or death) and follow up was undertaken at 6, 12, 18 and 24 months after onset. The statistical analysis was performed by means of SPSS/PC+package to determine the longterm prognostic factors. RESULTS: The multiple stepwise regression analysis revealed that the outcome depend on NIH scale(p<0.001), age (p<0.01), previous stroke(p<0.01), loss of consciousness (LOC) at onset (p Follow-Up Studies ; Humans ; Paresis ; Prognosis ; Prospective Studies ; Risk Factors ; Socioeconomic Factors ; Stroke ; Unconsciousness

We report a 18 years old man of brainstem encephalitis with acute ataxia, areflexia and gaze evoked vertical and horizontal nystagmus which is mimicking Miller Fisher syndrome. He had evidences of both peripheral neuropathy in nerve conduction studies and a brainstem encephalitis in MR findings. The possible relationship of the Miller Fisher syndrome and brainstem encephalitis are discussed with brief review of literature.

High dose intravenous immunoglobulin (IVIg) therapy can improve the clinical course of several immune mediciated diseases. We evaluated clinical effects and side effects of IVIg in Guillain-Barre syndrome (GBS). 19 Patients with GBS were studied prospectively in a placebo-controlled trial. 11 Patients were received high dose IVIg (400mg/kg for 5 days) and controls received only conservative treatment. The disability scores using modified Rankin scores before and after treatment of each group were compared. Four weaks later, mean Rankin Score of IVIg group was 2.5 + 0.7 and control group was 3.3+ 0.5which showed significant difference(p<0.05). There were no serious advers effer of promote early improvement with safety in acute phase of Guillan-Barre syndrome.

The benign mesenchymoma, in which fibrous tissue is accompanied by two or more mesencymal components, occurs very rarely in the head and neck area. The majority appear in patients under 25 years of age, most commonly in the subcutaneous scalp, cheek, or tongue. There is a 20% recurrence rate. Wide surgical excision is the treatment of choice. We report a case of mesenchymoma in the nasopharynx which was removed by transpalatine approach with a brief review of literature.

Purpose: Preoperative tumor size is associated with clinical stage, treatment plan and even survival rate of patient. We investigated the accuracy of tumor size estimation between magnetic resonance imaging (MRI) and ultrasonography (US) findings, comparing these with pathologic tumor size in the diagnosis of early breast carcinoma. Methods: Between 2011 and 2016, 136 patients with early breast cancer were analyzed and their tumor size on US and MRI findings were compared with their pathologic tumor size retrospectively. The background parenchymal enhancement of MRI was categorized as minimal, mild, moderate, and extreme. The patients who underwent neoadjuvant chemotherapy, had positive resection margins, underwent excisional biopsy for cancer diagnosis, and had non-mass lesions on MRI scans, were excluded. Results: In all, 83.1% of the cases showed concordance between MRI findings and pathologic tumor size within 0.5cm. MRI overestimated the findings by 10.3% and underestimated them by 6.6%; 78.7% showed concordance between US findings and pathologic tumor size within 0.5cm. US overestimated the findings by 5.9% and underestimated them by 15.4%. The tumor size on MRI (r=0.87) showed a stronger correlation to the pathologic tumor size than that on US (r=0.64) in early breast cancer patients. US had a tendency to underestimate the tumor size. The degree of breast parenchyma did not affect the accuracy of the measurement of preoperative tumor size. Conclusion MRI is relatively more accurate than US for assessing preoperative tumor size in breast cancer patients. US tends to underestimate tumor size.
