Idiopathic neuralgic amyotrophy (INA) is known as Parsonage-Turner syndrome or idiopathic brachial plexitis and is characterized by sudden onset of severe limb pain, followed by weakness and atrophy of limb. There is no specific tests for the diagnosis of INA. The diagnosis of INA is mainly dependent on the clinical history and electrodiagnostic study. It is often confused with more common disorders such as acute cervical radiculopathy, rotator cuff tear, or acute calcific tendinitis. A few recent reports have revealed that magnetic resonance image (MRI) of brachial plexus and shoulder can be helpful in the diagnosis of INA. We report two cases of classic INA in which MRI enhanced specificity and confidence in the diagnosis. MRI of the brachial plexus and corresponding limb as well as cervical spine should be included in patients clinically suspected of INA.

PURPOSE: The purpose of our study was to identify the CT findings that help detect pleural dissemination from lung cancer and to evaluate the usefulness of selected diagnostic criteria. MATERIALS AND METHODS: After a computerized database search of 606 patients who had undergone thoracotomy for primary lung cancer, 23 patients were identified as h aving surgically documented pleural dissemination. From the same database, 50 patients without pleural dissemination during thoracotomy were randomly selected as controls. Preoperative CT scans and medical records were rev i ewed retrospectively, and findings were compared between the two groups. RESULT: One or more of three types of pleural thickening (plaque-like, nodular, and fissural) were identified on CT as the most discriminating finding (sensitivity, 74 % ; specificity, 60 %; p = 0.007). The following findings were also significantly discriminating (p<0.05): contiguity of primary tumor with the pleural surface as seen on CT; adenocarcinoma in cell type; and a peripheral tumor defined as one in which bronchoscopy revealed no endobronchial lesion. The use of combinations of these findings in addition to pleural thickening rendered diagnostic criteria more specific at the cost of the sensitivity. CONCLUSION: During preoperative CT evaluation of lung cancer, the recognition of subtle pleural thickening helps detect pleural dissemination. The likelihood that subtle pleural thickening represents pleural dissemination is increased when a primary tumor is contiguous with the pleural surface, is an adenocarcinoma, or is peripherally located.

PURPOSE: To evaluate factors influencing the CT assessment of mediastinal lymph node metastasis in patientswith non-small cell lung cancer. MATERIALS AND METHODS: CT scans of 198 patients who had undergone thoracotomyand mediastinal lymph node dissection for non-small cell lung cancer were retrospectively evaluated using a sizecriterion of > or = 10mm in the short axis. To evaluate the accuracy of CT in diagnosing lymph node metastasis on anodal station-by-station basis, CT and pathological results were correlated. Analysis included a comparison of thesensitivity and specificity of CT according to 1) cell type of tumor, squamous cell carcinoma versusadenocarcinoma (excluding bronchioloalveolar cell carcinoma) ; 2) histologic differentiation;3) tumor size;4)central and peripheral of the tumor;5) the presence or absence of obstructive pneumonitis and/or atelectasis;6)the presence or absence of prior granulomatous disease. RESULTS: The overall sensitivity, Specificity, positive predictive value, and negative predictive value of CT in diagnosing mediastinal lymph node metastasis were 65%,84%, 43%, and 93%, respectively. Sensitivity for squamous cell carcinoma (72%) was significantly higher than thatfor adenocarcinoma(44%)(p<0.01). Higher specificities were noted in patients without obstructive pneumonitisand/or atelectasis(91% versus 75%)(P<0.01), and with a peripherally located tumor (90% versus 82%)(P<0.01).sensitivity and specificity were not appreciably altered by other variables. CONCLUSION: In the CT assessment ofmediastinal lymph node metastasis the cell type of adenocarcinoma adversely affected sensitivity, with a highfrequency of normal-sized metastatic nodes. Obstructive pneumonitis caused by central tumor adversely affectedspecificity with the frequent occurrence of hyperplastc nodes.

Endoscopic variceal ligation(EVL) is newly developed method to manage esophageal variceal bleeding. This study asse initial control rate of active variceal bleeding, incidence of rebleeding and complications in EVL. From June in l992 to December in 1994, this study was performed on 70 patients who had visited to our medical center for melena or hematemesis by acute esophageal variceal bleeding. In all of 70 cases, eradication of esophageal varix was performed and variceal bleeding was controlled well. And first session was performed successfully with EVL. But rebleeding was occured in 12 cases(11 cases caused by esoyhageal varix and 1 case caused by esophageal ulcer) during follow-up period, so EVL therapy was performed repeatedly and 8 cases were eradicated and 4 cases were uncontrolled and died, and then 94% hemostatic effect was achieved during follow-up period. Complications of EVL therapy were mild(substernal discomfort in 12 cases, substernal pain in 4 cases, fever in 3 cases, mild dysphagia in 2 cases) and well controlled. Superficial esaphageal ulcer was shown in 18 cases by follow-up endoscopy after 1 week. These results show that EVL is a good therapeutic method to control active variceal bleeding and eradication of varix with repeat treatment. In conclusion, EVL is an effective and safe method of treatment and prevention for esophageal variceal bleeding.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

Anti-leucine-rich glioma inactivated-1 (LGI1) antibody has been known as the most common antibody in autoimmune limbic encephalitis. We report a case of a 63-year-old woman who presented with repetitive memory impairment. She was diagnosed with anti-LGI1 limbic encephalitis by clinical symptoms, magnetic resonance imaging, electroencephalography, and antibody test. Hepatocellular carcinoma (HCC) was discovered incidentally. Clinical seizures were completely controlled after hepatic segmentectomy without immunotherapy. This is the first case report showing the relationship between HCC and anti-LGI1 limbic encephalitis.
