Wernicke encephalopathy is usually accompanied with peripheral neuropathy, known as dry beriberi. In contrast, wet beriberi presenting as cardiovascular symptoms rarely occurs. The acute type of wet beriberi can be fatal, if untreated quickly. It is reported that the cerebellar vermis has a role of the coordination and control of cardiovascular and autonomic reflex activities. We report a 58-year-old man showing acute wet beriberi in Wernicke encephalopathy with cerebellar vermis lesion.

Recent development and advances in arthroscopic surgical techniques for Anterior Cruciate Ligament(ACL) reconstruction have led to the single-incision techniques. Several potential pitfalls in the classic single-incision techniques were found and it has become necessary to develop a new, simpler method to overcome these problems. Seventy-five cases of arthroscope-assisted ACL reconstruction were prospectively studied. The radiologic results were compared between the group in which femoral tunnel preparation was performed by the tibia tunnel(classic technique, 35 cases) and the group in which the anteromedial portal was employed(modified technique, 40 cases). Significantly better results were obtained at the angle formed by the bone graft and the interference screw, the angle between the femoral tunnel axis and the anatomic axis of the femur, and the angle between the femoral tunnel axis and tibial tunnel axis in the modified technique(P<0.05). This study presents a modified arthroscope-assisted ACL reconstruction technique that uses the anteromedial portal for femoral tunnel preparation and insertion of interference screw. In the modified ACL reconstruction technique, the femoral tunnel preparation and femoral graft fixation were accomplished in the same direction and the femoral tunnel preparation was performed regardless of the tibial tunnel preparation, this allows the surgeon to handle the arthroscope freely and advance more posteriorly to get a better view of the posterior cortex.

BACKGROUND: The video-assisted thoracic surgery (VATS) with 2 mm thoracoscopy in primary spontaneous pneumothorax (PSP) was known to be unreliable in its accuracy and recurrence rate. We compared 10 mm VATS with 2 mm VATS in the results of operation. MATERIAL AND METHOD: From Sept. 1998 to Dec. 2002, 176 cases (10 mm VATS; 73 cases, 2 mm VATS; 103 cases) of PSP were treated by VATS bleb resection at Korea University Ansan Hospital. 10 mm thoracoscope, 5 mm port, and 5 mm instruments were used in 10 mm VATS group, and 2 mm thoracoscope, 2 mm ports and 2 mm instruments used in 2 mm VATS group. In the two groups, staples were inserted through 11.5 mm port for chest tube. RESULT: The mean follow-up duration was 20.8+/-16.1 months in 10 mm VATS group, and 13.9+/-8.2 months in 2 mm VATS. The most common indication of operation was a recurrent pneumothorax (34%) in 10 mm VATS and patient's desire (40%) in 2 mm VATS, respectively. The operation time, number of staples used in operation, postoperative chest tube keeping days, postoperative total amount of drainage, and postoperative hospitalization days were statistically lower in 2 mm VATS. Other significant variables affecting the operation time in linear regression analysis were the number of staples that used in operation, the presence of pleural adhesion, and type of pleurodesis and thoracoscope used in operation. However, R2 values were lower than 0.1. The postoperative recurrence rate was 2.7% in 10 mm VATS and 2.9% in 2 mm VATS. It was not significant statistically. Recurrent cases developed within 1 year in both groups but the difference was statistically insignificant. CONCLUSION: Although there were differences in follow-up duration between two groups, the operation time, number of staples that used in operation, postoperative chest tube keeping days, postoperative total amount of drainage, and postoperative hospitalization days were statistically lower in 2 mm VATS. And in 2 mm VATS, there were no technical difficulties during operation and no differences in recurrence rate from 10 mm VATS. As a result, we suggest that 2 mm VATS can be used in the treatment of PSP.

Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is a slowing progressive ataxic disorder characterized by bilateral vestibulopathy, cerebellar ataxia and somatosensory impairment. Autonomic dysfunction is recently considered as a core feature in CANVAS in addition to these symptoms. In most cases, patients with CANVAS show cerebellar atrophy in brain imaging, but some cases show minimal or no atrophy of cerebellum. Brain (18F)-fluoro-2-deoxy-D-glucose positron emission tomography (¹⁸F-FDG PET) study can be a complimentary tool to diagnosis CANVAS in cases of no structural abnormality such as cerebellar atrophy. Hereby, we present a case of CANVAS with minimal atrophy of cerebellum but showing a prominent hypometabolism in cerebellum, thalamus and posterior cingulate cortex in ¹⁸F-FDG PET.

Focal subarachnoid hemorrhage occasionally presents as transient focal neurologic episodes mimicking transient ischemic attack (TIA). Unless properly diagnosed, it may aggravate cerebral hemorrhage by administering antithrombotic agents. Therefore, clinicians need to be aware that such focal subarachnoid hemorrhage sometimes cannot be detected on noncontrast computed tomography and blood-sensitive magnetic resonance imaging can detect even a small amount of hemorrhage. We describe an 85-year-old woman with focal subarachnoid hemorrhage and possible cerebral amyloid angiopathy who presented transient left arm weakness recurrently, which mimicked TIA.

PURPOSE: Epileptic patients have a increasing tendency to develop seizure attack in high temperature. This finding suggests that high temperature may have an effect on neuronal hyperexcitability and injury of epileptic brain. Therefore, the influence of high temperature on normal and epileptic brain was studied in organotypic explant cultures of rat. METHODS: Fourteen days-in-vitro cultures from 8 day-old rat pups were perfused with standard aCSF bubbled with 95%/5% O2/CO2 in a microchamber. Stimulus train(0.3 sec, 60 Hz) was applied to Schaffer collaterals in CA3 and extracellular field potential was recorded in the CA1 pyramidal layer. At 36degrees C initially, AD was evoked. In high temperature(HT) group, the cultures were subjected to 39degrees C for a period of 8 min before the second stimulus train was applied. They were then restored to 36degrees C for 10 min. In normal temperature group, temperature was maintained at 36degrees C for the second stimulus train. The cultures were returned to the incubator and observed serially for neuronal damage. Intensity of propidium iodide fluorescence indicative of neuronal injury was quantitated by digital image analysis. The cultures on the same insert that were not stimulated served as the unstimulated groups. RESULTS: There was not a statistically significant difference in neuronal damage between the unstimulated high-temperature(HT) and normal-temperature(NT) group. In CA1 sector, % damage(mean+/-SEM) was 0.42+/-0.20 vs 0.27+/-0.05 at 24 hrs(HT vs NT group, n=16 each, P>0.05, Student t-test); 1.81+/-0.79 vs 1.43+/-0.27 at 48 hrs(P>0.05); 3.50+/-1.32 vs 3.35+/-0.56 at 72 hrs(P>0.05). In CA3 sector, % damage was 0.34+/-0.10 vs 0.20+/-0.03 at 24 hrs(P>0.05); 0.99+/-0.20 vs 0.83+/-0.23 at 48 hrs(P>0.05); 2.00+/-0.38% vs 2.26+/-0.35% at 72 hrs(P>0.05). Neuronal damage on AD induced cultures during febrile setting(n=16) was significantly higher than in nonfebrile setting(n=16). In CA1 sector, % damage was 6.63+/-2.56 vs 0.92+/-0.45 at 24 hrs(febrile setting vs nonfebrile setting, P= 0.036); 26.37+/-7.44 vs 4.99+/-2.23 at 48 hrs(P=0.010); 38.59+/-9.63 vs 6.48+/-2.30 at 72 hrs (P=0.003). In CA3 sector, % damage was 1.23+/-0.48 vs 3.91+/-2.37 at 24 hrs(P=0.277); 13.09+/-5.75 vs 5.93+/-3.27 at 48 hrs(P=0.288); 27.86+/-8.68 vs 7.54+/-3.74 at 72 hrs(P=0.04). CONCLUSION: At high temperature, seizures in epileptic brain may be more injurious than seizures in normal temperature.

PURPOSE: To evaluate the changes and remission of disease activity with changes in inflamed synivial volumes of rheumatoid joints after therapy. MATERIALS AND METHODS: Seven rheumatoid arthritis patients who had been treated with antiinflammatory drugs were followed up. Using NIH imaging and a segmentation technique, pre- and post-enhanced images were measured in subtracted images. Intra- and interobserver variation were evaluated by two radiologists(A and B), using two independent measurements. For comparison, the cases were assigned to one of two groups : remission and non-remission. Changes in ESR and total joint counts(TJC) after therapy were compared with inflamed synovial volumes. RESULTS: Intraobserver variations were 3.2% and 2.7% in A and B, respectively, interobserver variation between A and B was 7.1%. Changes in inflamed synovial volumes correlated well with those in ESR (r=0.88, p<0.009) and TJC (r=0.78, p<0.037) after therapy. Changes between the remission and non-remission group were insignificant, however. CONCLUSION: Changes in inflamed synovial volumes reflect those in the activity of rheumatoid arthritis between pre- and post- treatment. This technique may be used as a tool for predicting therapeutic response in rheumatoid arthritis cases. Changes in inflamed synovial volumes are of limited value, however, in predicting the remission of rheumatoid arthritis after therapy.
