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.

The measurement of gastric emptying time is useful in differentiation of the hypochondriacal neurosis from the functional gastrointestinal disturbance, and also useful in searching the hidden gastro-intestinal disease in patients who are believed as the functional gastrointestinal disturbance. We confirmed in this study that the more delayed gastric emptying time was measured in functional gastrointestinal disturbance compared to normal group, and more shortened gastric emptying time was found after treatment with dopamine antagonist (cleboril) in this group.

Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

Transient hyperkalemia has been reported to occur in eletric burn patients following intravenous administration of succinylcholine. We have studied the origin of the elevated serum K+ concentration after injection of succinylcholine from both the non-burned area and from the burned area in electirc burn patients. Blood samples for serum K+ measurement were drawn 1,2,3,4,5 and 10 minutes after administration of succinylcholine from both the burned are and the non-burned area in 6 electric burn patients. The following results were obtained: 1) Serum K+ levels increased in the burned group in 3 minutes after injection of succinylcholine. 2) The serum K+ concentration of venous samples from the electric burn area were more increased than from the non-burned area injection of succinylcholine.

Rigid posterior fixation of the atlas to the third and fourth cervical spine was achieved in a patient in whom axis pedicle fracture and dislocation of axis on the third cervical spine. Althouth there was no evidence of neurologic disorder, marked instability of axis on the third cervical spine should inevitably be fused in any procedures. An anatomically contoured loop was secured to the posterior arch of the atlas and the laminae of the third and the fourth cervical spine by sublaminar wirings. The technique has the advantage over bone graft, either alone or with cement, in that it affords rigid stabilization, allows early mobilization and some flexion movement of atlanto-occipital joint.

Of several possible configurations of pin fixation of a displaced supracondylar fracture of the humerus in children, the medial and lateral crossed pinning technique has been known to provide the greatest resistance to gross rotational displacement. A new technique with ipsilateral two lateral crossed pins was devised so as to avoid the ulnar nerve injury with good stability for fracture site. During the period from 1992 to 1994, 18 children with displaced supracondylar fracture of the humerus were treated by closed reduction and ipsilateral two lateral crossed pinning. Eighty nine percents of the final results were satisfactory. There were no ulnar nerve injuries and fixation loss in all cases from the treatment. This is a safe, simple and reliable technique for providing the good stability of fracture site as well as avoiding the ulnar nerve injury.

The fundamental alterations in the cardiovascular system that occur consequent to aging are of great pratical importnace to clinicians. Senescent cardic muscle has many features of prolonged tension development, impaired relaxation and diminished response to receptor-mediated inotropic interactions. We estimated left ventricular mass by 2-D echo area-length method using a high quality planimeter. Age-related increments in left ventricular mass demostrated, but left ventricular enddiastolic cavity volumes were unaffected by age. The increase in left ventricular mass observed with aging is typical of pressuer-overload hypertrophy and its stimulus may be increased afterload from senescent changes.
