The authors described a case of male schizophrenia who developed myoclonic jerk repeatedly and one episode of convulsive seizure during the treatment of clozapine. According to literatures and reported cases, myoclonic jerks induced in a small amount of clozapine may precede and predict the development of a convulsive seizure. Therefore clinicians have to pay attention to the development of a myoclonic jerk during the administration of clozapine. They may decrease the dosage of clozapine step by step at first in the convulsive state, and observe EEG changes of patients frequently.

OBJECTIVES: Acrylamide is a neurotoxin inducing central-peripheral distal axonopathy. The authors evaluated several neurologic tests to screen the early effect of occupational acrylamide exposure. METHODS: Fifty-two males working either in the production of acrylamide monomer or in the handling of acrylamide in Ulsan, Korea, were selected and subcategorized into the high-exposure group (n=10, mean age of 30. 4 years) and the low-exposure group (n=42, mean age of 28.9 years). Twenty-three males (mean age 29.4 years) from medical professionals and students were chosen as a non-exposed reference group. Symptom questionnaire, neurologic examination, electrodiagnostic test, vibrotactile threshold test, and Lanthony desaturated 15 panel test (LD-15D) were done. RESULTS: The high-exposure group showed more number of specific symptoms on questionnaire and more abnormal two point discrimination test. High-exposure group showed a significant difference in the median motor conduction velocity, peroneal nerve motor latency, sensory amplitude of median nerve action potential, and sensory latency of sural nerve. The vibrotactile threshold of the high-exposure group was significantly higher in both hands and feet than that of the low-exposure group and the reference group. Average color confusion index on the LD-15D was significantly higher in the high-exposure group (median 22.7, range 0-135.7) than in the reference group (median 2.4, range 0-33.2). CONCLUSIONS: The symptom questionnaire, vibrotactile threshold test, and color discrimination test are sensitive in detection of the early acrylamide-induced neuropathy, and the combination of these tests would further facilitate the effectiveness of the screening.

OBJECTIVE: The purpose of this study was to investigate possible menopause related changes in circulating insulin-like growth factor binding protein 3 (IGFBP-3) levels and their relationship with insulin-like growth factor 1 (IGF-1) plasma levels, osteocalcin(Ost) and urinary deoxypyridinoline(Dpd) in either surgical menopause or natural menopause, METHOD: Seventy-two postmenopausal women (surgical menopause 48, natural menopause 24) were invited to participate in this study. In all subjects plasma IGF-1 and IGFBP-3 levels were measSURED by radioimmunoassay and Ost and Dpd were measured by enzyme linked immunosorbent assay(ELISA). RESULTS: No difference was found between mean IGFBP-3 plasma levels in the two groups studied(3,522 +/- 926 vs 3,854 +/- 569 ng/ml), while mean IGF-1 levels were significantly lower in natural menopause as compared with surgical menopause (natural 126 +/- 44 vs surgical 163 +/- 66 ng/ml, p=0.007). No difference was found between mean Ost levels in the two groups studied (natural menopause 8.0 +/- 2.9 vs surgical menopause 8,9 +/- 2.1 ng/ml, p=0.113) and mean Dpd levels in the two studied (natural menopause 6.8 +/- 2.3 vs surgical menopause 7.8 +/- 3.4 mM, p=0.213). CONCLUSION: IGF-1 was significantly lower in natural menopause as compared with surgical menopause, but no significant difference was found in IGFBP-3, Ost, and Dpd levels

Double-orifice mitral valve is a rare congenital anomaly. Most cases of double-orifice mitral valve are hemodynamically normal and remain symptomless, so that it is usually discovered incidentally in autopsy or during surgical correction of a cardiovascular abnormality. Recently, however, it is increasingly recognized as such, since the echocardiography has gained wide acceptance as a non-invasive diagnostic tool by the M-mode, two-dimensional and color Doppler echocardiogram. Two separate mitral valve apparatuses can be used on the M-mode echocardiogram. In the two-dimensional echocardiography, the parasternal and subcostal short-axis views can show two separate glass-like orifices in the left ventricle, and the parasternal long-axis view as well as the apical four-chamber view can show the anomaly. And the color Doppler echocardiogram can visualize two mosaic-pattern flows between the left atrium and ventricle. We present herewith two cases of double-orifice mitral valve, as diagnosed by means of echocardiography. The first case was an isolated one with mitral stenosis, showing two parachute mitral valves. The second was associated with perimembranous ventricular septal defect, and showed the accessory mitral valve directly attached to the ventricular septum, with the chordae crossing the ventricular outflow tract.
