The effect of oral mexiletin was evaluated by a 10-day double-blind cross-over protocol on 10 subjects with chronic stable high-frequency ventricular premature beats referred to our cardiology clinic from February through July, 1982. Total daily doses were either 450mg or 600mg in three divided portions depending on body weight. The frequency of the premature ventricular beats was measured by 3 separate 24-hour ambulatory EKG recordings by dual-channel Holter monitor on each patient. Mexiletine was judged to be effective in suppressing the ventricular arrhythmias when the 24-hour PVC-counts during the study-drug period showed a decrease by 80% and the hourly average PVC-counts by 70% compared with those of the equivalent intervals of both the baseline and the placebo periods. Mexiletine was effective in 5 of the 10 subjects. Mild tremor and anorexia were noted in 2 patients, but they were able to comply with the study protocol in spite of these minor side effects. Blood level measurements were not done in this study for lack of such facility, the utilization of which would undoubtedly enhance the therapeutic effectiveness of the antiarrhythmic agent in the individualization of treatment.

This study was conducted to determine the level of inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with meningitis. All the CSF of the patients were examined by Gram and acid-fast stain, culture, and PCR for Mycobacterium tuberculosis and Mycoplasrma spp..The levels of sugar, protein and leukocytes count were also evaluated in the CSFs. Concentrations of Interleukin (IL)-1B, IL-6, IL-8, tumor necrosis factor (TNF)-a in the CSF were evaluated by the ELISA kit (Genzyme, USA). General bacteria, tubercle bacilli, and Mycoplasma spp. were not detected with stain and culture methods, but, Mycoplasma spp. was detected by PCR method from four (6.3%) patients with meningitis. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-cx in the control group were 0.6+/-0.2, 896.8+/-107.6, 50.1+/-5.1, and 4.8+/-1.4 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with aseptic meningitis were 3.8+/-0.6, 1261.6+/-144.3, 466.7+/-42.3, and 10.8+/-2.0 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with mycoplasmal meningitis were 10.2+/-8.1, 1979.5+/-133.8, 459.7+/-96.4, and 17.5+/-5.1 pg/ml, respectively. There were significantly differences in the levels of IL-1B, IL-6, IL-8, and TNF-a between control and patients with aseptic meningitis or Mycoplasmal meningitis (each p<0.001). These results suggest that increased levels of IL-1B, IL-8, and TNF-a could be higly suggestive of meningitis.

OBJECTIVES: Risperidone, an atypical antipsychitics which blocks both dopaminergic and serotonergic receptors, have a good response to the negative symptoms as well as positive symptoms, and improve cognitive dysfunction of schizophrenic patients. Furthermore, it has few extrapyramidal side effects and tardive dyskinesia. Although it had been reported that the atypical antipsychotics have less effect on prolactin(PRL) than the classical antipsychotics, we could experience PRL-associated symptoms such as amenorrhea, galactorrhea and hyperprolactinemia in practice. Therefore we tried to identify the sex differences of risperidone-induced hyperprolactinemia, to evaluate factors affecting PRL levels, and to know the association between cognitive disorders and PRL. METHODS: The baseline levels of PRL and TSH prior th risperidone administration were measured by enzyme immunoassay method for 50 patients (25 males and 25 females) admitted with schizophrenia, schizoaffective disorder or schizophreniform disorder according to the DSM-IV classification, and the measurements of PRL were repeated on the 2nd and the 4th wks of risperidone administration. Concomitantly, the severity of psychotic symptoms using CGI, BPRS and PANSS, and the cognitive dysfunction using PANSS-CF were assessed prior to, on the 2nd and the 4th wks of risperidone administration. The PRL and TSH levels of 54 healthy controls(29 males and 25 females) who had no medical, neurological and psychiatric illnesses were also evaluated. Furthermore, the correlation with the psychiatric diagnosis, education, age, sex, duration of illnesses, risperidone dosage, duration of risperdone administration, TSH concentration, cognitive function, severity of psychotic symptoms were also identified. RESULTS: 1) The baseline PRL levels of female schizophrenics(74.3+/-49.6ng/ml) were significantly(p<0.005) higher than those of males(36.3+/-24.6ng/ml), which wee significantly(p<0.0001 respectively) higher than those of controls(females 16.9+/-6.1ng/ml, males 13.3+/-4.9ng/ml). The PRL levels measured on the 2nd wks(females 133.7+/-47.8ng/ml, males 56.9+/-23.6ng/ml) and on the 4th wks(females 146.1+/-45.9ng/ml, males 70.0+/-31.5ng/ml) after risperidone administration were significantly(p<0.0001 respectively) higher in females. The mean dosages of risperidone on the 2nd wks were 3.8+/-1.7mg(2-6mg) for the females and 4.0+/-1.6mg(2-6mg) fore the males, and on the 4th wks were 4.5+/-2.1mg(2-8mg) fore the females and 5.4+/-2.2mg(2-8mg) for the males. 2) The rise of PRL levels were positively correlated with increased risperidone dosage in males(y=0.307 on the 2nd wks and y=0.280 on the 4th wks), while they were not correlated with dosages in females. For the females, the PRL levels were negatively correlated(y=-0.320) with decrease of TSH concentration. The baseline PRL levels were not correlated with age, education, duration of illnesses, psychopathology, cognitive disorders in both males and females, while it was negatively correlated with TSH levels only in females(y=-0.320). 3) The cognitive dysfunction was correlated with PRL levels in males, while PANSS-CF scores were negatively correlated with PRL levels(y=-0.220 on the 2nd wks and y=-0.366 on the 4th wks) in females. The psychopathology was positively correlated with cognitive dysfunction in both males and females. Therefore, the risperdone-induced cognitive improvement seemed to be correlated with improvement of psychopathology in both males and females, and with increase in PRL levels only in females. CONCLUSIONS: The fact that the serum PRL levels of schizophrenics were higher than those of controls, especially in females suggested that it could be related with risperidone dosage in males and with primary pathological process in females. The risperidone-associated cognitive improvement seemed to be related with general improvement of psychopathology as well as the rise of PRL levels especially in females. The facts that the effect of risperidone-induced hyperprolactinemia and the cognitive function were more in females suggested that somewhat different mechanisms could be exerted on them.

PURPOSE: Porous orbital implant Medpor(R) which is made of polyethylene is being widely used currently. Compared with previously used porous orbital implants, it is somewhat preferred due to cheaper and easier usage but reports on its postoperative complications are not sufficient. We report the first case of Medpor(R) infection developed domestically. METHODS: A 20 year-old male patient was admitted with Medpor(R) infection 14 months after Medpor(R) orbital implant insertion. He was treated with antibiotics. RESULTS: Infection was controlled with antibiotics without implant removal. Implant exposure occurred after infection control so dermis graft was done.

Purpose: Paclitaxel, on systemic administration, is widely known to be effective in the treatment of bladder cancer. However, the intravesical use of paclitaxel has not been attempted because of its liposolubility and direct toxicity to the bladder mucosa. The purpose of this study was to evaluate the efficacy and toxicity of paclitaxel-loaded glyceryl monooleate (GMO) in the intravesical treatment of superficial bladder cancer, by enhancing its bioadhesiveness and bioavailability. Materials and Methods: 12 mice were divided into two groups, and bladder carcinomas induced by the addition of 0.05% BBN to their drinking water for 12 weeks. Group 1 received an intravesical instillation of 0.1ml GMO-paclitaxel-free buffer and Group 2 an intravesical instillation of 0.1ml GMO-paclitaxel. On day 21, the tumor incidence, bladder weight and toxicity were evaluated. Results: The incidence of cancer in groups 1 and 2 were 83 and 17%, respectively. The incidence of cancer was significantly reduced in group 2 compared to group 1 (p<0.05). There was a tendency for the average bladder weight in group 1 to be heavier than that in group 2, but there was no significant difference (p=0.375). There were no liver, kidney or bone marrow toxicities in either group. Conclusions: Intravesical GMO-paclitaxel therapy may have an inhibitory effect on the growth of superficial bladder cancer in a BBN-induced bladder cancer model; therefore, it could potentially be used in those patients showing little to no response to intravesical Bacillus Calmette- Guerin (BCG) or other anticancer drug therapies.

The purpose of this study was to evaluate the anatomical outcomes of vitrectomy with internal limiting membrane removal in highly myopic eyes with retinal detachment caused by a macular hole. Nineteen, consecutive, highly myopic eyes with full thickness macular hole with retinal detachment were treated by vitrectomy with internal limiting membrane removal, endolaser photocoagulation on the center of the hole and fluid gas exchange. In five eyes with other peripheral breaks, scleral buckling (3 cases), encircling (1 case) and barrier laser (1 case) were combined. In 15 eyes (79.0%) the macular hole was closed after the initial surgery. In 4 eyes (21%) the macular hole was reopened, but these were successfully treated with fluid gas exchange (1 case) or macular buckling (3 cases). The visual acuity was improved in 15 eyes (79.0%). In conclusion, these results suggest that the removal of the perifoveal internal limiting membrane may be an important adjuvant in the treatment of the myopic macular hole with retinal detachment.

BACKGROUND: Total obstruction of the left main coronary artery is a common cause of sudden death but is rarely seen in patients who survive to undergo diagnostic evaluation or treatment. METHODS: During twenty six-year period, we encountered 5 patients with chronic total obstruction of the left main coronary artery out of about 4,000 patients who underwent coronary angiography. RESULTS: All patients have undergone coronary bypass surgery. These patients present with increasingly severe angina. A right dominat coronary anatomy is always found, usually with well-developed right-to-left collaterals. Left ventricular function was severely impaired in two patients out of five patients. CONCLUSIONS: The results of surgical revascularization in our patients and others described in the literature can support the safety and efficacy of this approach.
