STUDY DESIGN: Case report OBJECTIVES: To report a case of Brown-Séquard syndrome after blunt cervical trauma. SUMMARY OF LITERATURE REVIEW: Brown-Séquard syndrome is a rare disease characterized by hemisection of the spinal cord, and it shows the best prognosis of the various types of incomplete spinal cord injuries. MATERIALS AND METHODS: A patient with Brown-Séquard syndrome that occurred after a traffic accident was followed up for 2 years and 6 months. RESULTS: We observed normal recovery of motor strength, but sensory impairment and deep tendon hyperreflexia remained. CONCLUSIONS: Brown-Séquard syndrome is known to have a good prognosis, but in this case, the neurological abnormality did not fully recover; therefore, we report this rare case and present a review of the literature.

BACKGROUND: The improved technique for cardiopulmonary resuscitation(CPR) has resulted in the survival of many patient who experienced cardiac arrest. However, mortality in resuscitated patients is high, and the survival rate without brain damage is very low. Various neurological examination models, neuro-imaging techniques, electrophysiological procedures, and biochemical tests have been studied with respect to the detection of cerebral damage and outcome, but an early, reliable prediction of individual outcomes is still uncertain. METHODS: We studied twenty patient who had been in a coma for more than 24 hours after CPR, Somatosensory evoked potentials(SEP) were measured within the first three days after CPR. RESULTS: Of the twenty patients, seven patients(35%) had a good outcome, and thirteen patients(65%) had a bad outcome. Of the eleven patients with loss of the cortical evoked potential's N20 peak, all had a bad outcome. CONCLUSION: SEPs are of great benefit in prognostic evaluation after CPR.

Purpose:
This study examined the changes in the body mass index (BMI) and the effects of BMI on the knee function and risk factors for an increase in BMI after total knee arthroplasty (TKA) in Asians.
Materials and Methods:
A prospective observational study was conducted on 100 cases of TKA performed by one surgeon. Obesity was defined as BMI ≥25 kg/m 2 . The BMI and Knee Society Score, consisting of the Knee Score and Function Score, were measured on the day before surgery and one year after surgery.
Results:
The BMI decreased or was maintained in 34 cases (34%) and increased in 66 cases (66%) one year after surgery. An increase in BMI of 5% or more was considered a clinically significant increase in BMI and occurred in 28 cases (28%). The patients with an increased BMI by more than 5% showed a significantly lower knee function score. The age and preoperative function score were significantly associated with an increased BMI by more than 5%. As the age increased by one year, the odds ratio at which the BMI would increase by more than 5% one year after surgery was 0.905. Moreover, as the preoperative function score increased by one point, the odds ratio that the BMI would increase by 5% one year after surgery was 0.902. In other words, a younger preoperative age and a lower preoperative function score mean a higher risk of a more than 5% postoperative increase in BMI.
Conclusion
The BMI increased by more than 5% one year after surgery in 28% of the TKA patients examined. They had a lower functional score. The risk factors for a more than 5% increase in BMI after TKA were young age and a low preoperative function score. Therefore, surgeons should educate patients, particularly those who are young or have a low preoperative function score, so that the patient’s BMI would not increase after surgery.

To delineate the coronary anatomy and the left ventricular function during early myocardial infarction, coronary arteriography and left ventriculography were performed prospectively in 28(34%) of 83 patients who were admitted to the coronary care unit at Severance Hospital from November 1983 to August 1984 within 30 days(median : 14 days;range : 4 hours to 30 days) after the onset of symptoms. The frequency of total occlusion of the infarct related artery was evaluated in the time course of infarction. To prove spontaneous recanalization, 3 patients who had total coronary occlusion underwent serial study within 11-20 days after the first study. We categorized the patients into two comparable groups according to the infarction site, coronary angiographic findings, and age. Comparison of clinical and angiographic findings between each group was made. The following results were obained. 1) There were 23 patients with transmural myocardial infarction(82.1%) and 5 with nontransmural infarction(17.9%). Among 23 patients with transmural infarction, 14 had anterior infarction(60.9%) and 9(39.1%) inferior infarction. 2) The mean age was 51.3 years(range : 31-79 years). The ratio of male to female was 3.7:1. 3) Fifteen patients(53.6%) had one-vessel disease, 10(35.7%) two-vessel disease and 2(7.1%) three-vessel disease, One patient(3.6%) had insignificant disease(less than 50% reduction in luminal diameter). Nontransmural infarction had a tendency to be associated with higher prevalence of multivessel disease than transmural infarction(80% vs 34.8%). 4) In 23 patients with transmural infarction, 12(52.2%) had complete occlusion and 11(47.8%) incomplete occlusion of the infarct related artery. Three patients(13.0%) had subtotal occlusion(90-99%) and 4(17.4%) had lesions of 70-89% luminal diameter narrowing. Three patients(13.0%) had 50-69% lesions and the remaining 1(4.4%) had insignificant obstructive lesions. 5) Of the 23 patients with transmural infarction, 12 were studied within 14 days and 11 in 15-30 days after the onset of symptoms. The frequency of total coronary occlusion was significantly higher in the patients studied within 14 days of symptom onset vs those studied in the 15-30 days period(83.3% vs 18.2%;p<0.001). Serial studies of 3 patients with total coronary occlusion at the initial study demonstrated occurrance of spontaneous recanalization in 2 patients. 6) The left ventricular-ejection fraction was higher in the patients with nontransmural infarction, inferior infarction, and incomplete coronary occlusion(65+/-14%, 58+/-16% and 57+/-17%) than that of the patients with transmural infarction, anterior infarction, and complete coronary occlusion(51+/-15%, 47+/-14% and 46+/-13, p<0.05). But there was no significant difference in left ventricular ejection fraction between the young(<45 year) and the old(> or =45 year) age groups. And also 0-1 vessel disease and 2-3 vessel disease groups did not show significant difference in ejection fraction. The degree of congestive heart failure was more severe in the patients with anterior infarction than in those with inferior infaction. multi-vessel disease group was significantly older than 0-1 vessel disease group(55+/-8 yrs vs 46+/-12 yrs, p<0.05), and the young age group had a tendency to be associated with higher prevalence of single vessel disease. 7) As for the complications of angiocardiography in this study, there was ventricular finbrillation in 2 patients(7.1%) without mortality. It is concluded that coronary arteriography can be safely performed within one month after acute myocardial infarction;high prevalence of one-vessel disease in acute myocardial infarction in the Korean adult patients admitted to a general hospital;lower incidence of total coronary occlusion in the late time course of infarction due to spontaneous recanalization;better left ventricular function in the patient groups with nontransmural infarction, inferior infarction and incomplete coronary occlusion.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.

BACKGROUND: Acne is a relatively common disorder, especially in the adolescent. The condition is characterizecl by comedones, papules and pusi:ules. Acne patients frequently wash their face. Cleansing with an effective agent is therapeutic and preventive for patients suffering from acne vulgaris. OBJECTIVE: The study was designed to compare thc efficacy and safety of a facial clemser consisting of 1% triclosan and 0.5% Ku Shen and a in in the treatment of facial acne vulgaris. METHODS: The study was camed out on two groups of people: a treatment and a control group. Efficacy and safety were assessed at baseline and at weeks 1, 2, 3, 4, 6, 8, 10 and 12. Efficacy was determined by investigating counts of non-inflamatory open and closed comedones, and inflamatory papules and pustules. Global improvement was also assessed. RESULTS: At week 12, the mean counts in the differe,nt lesions were as follows; 11.2 versus 17.2 for total lesions (p<0.05); 9.4 versus 11.3 for non-inflammatory lesions (p<0.05); 1.8 versus 5.9 for inflammatory lesions (p<0.05) in the treatment and control group, respectively. A Statistically significant difference was observed in patients overall self-assessment (p<0.05). The Group applying the facial cleanser with 1% triclosan and 0.5% Ku Shen felt significantly better than the one applying the control facial cleanser. Some patients developed mild and transient local side effects. CONCLUSION: Cleansing three times a day with a facial cleanser consisting of l% triclosan and 0.5% Ku Shen was found to be effective ancl safe for patients suffering from acne vulgaris.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.
