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.

BACKGROUND: Excessive sweating, especially of the palms, soles and axillae, is a socially and an occupationally distressing, and sometimes disabling condition. A variety of treatment methods are used to reduce profuse sweating including topical agents, iontophoresis and symphatectomy. OBJECTIVE: We investigated whether a 20% aluminum chloride solution is efficient in the treatment of axillary and palmoplantar hyperhidrosis using a skin surface hydrometer. METHODS: We treated 31 patients (7; male, 24; female) by Drysol once a day at bedtime for four weeks. We had measured the conductances on the stratum corneum of the palms, soles and axillae using a skin surface hydrometer before and after treatment every week for four week RESULTS: There was a reduction of conductances after the treatment by Drysol (p<0.05). The reduction of conductances was continued for four weeks (p<0.05). CONCLUSION: Drysol is an efficient, safe, and simple method for initial treatment of the primary hyperhidrosis.

Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

Alzheimer's disease (AD) is an age-related disorder. Both the prevalence and the incidence of AD double approximately every 5 years after the age of 60. This is a particularly serious problem considering that the Korean elderly population is rapidly growing. We present three illustrative cases of AD in mild, moderate, and advanced stages, respectively. Their initial symptoms were memory impairment which was followed by language disturbance and visuospatial dysfunction. Abnormal behaviors such as delusion and aggression occurred in moderate and severe cases. The presence and severity of dementia in these cases were established by history taking, neurological examination, standardized mental status assessment, and neuropsychological test. Laboratory investigations showed no abnormalities that could account for the cognitive deficits. Brain CT or MRI findings of the patients wee not remarkable except for a diffuse atrophy demonstrated by increased ventricular volume, narrowed gyri, and widened sulci, As an addendum, risk factors, clinical symptoms, clinical diagnosis, and natural history of AD were reviewed.
