BACKGROUND: This study was performed to compare anesthetic agents and adjuvants for general anesthesia or regional anesthesia between university hospitals, resident-training general hospitals and hospitals without training program of residents. METHODS: We surveyed university hospitals, resident-training hospitals and hospitals without training program of residents and divided randomly each hospital groups to become twenty hospitals. We compared the use frequency of inhalation anesthetics, muscle relaxants, induction agents, reversing agents, local anesthetics, premedicants, cardiovascular drugs and plasma expanders. RESULTS: Enflurane was most commonly used inhalation anesthetic in all hospital groups. Isoflurane was less commonly used inhalation anesthetic in hospitals without training program of residents. Pancuronium was most commonly used muscle relaxant in university hospitals. Midazolam, ketamine, fentanyl, propofol were commonly used induction agents during induction in university hospitals and resident-training general hospitals. Differences of use frequency of local anesthetics among hospital groups were not significant, but epinephrine mixing with local anesthetics was more frequent in university hospitals and resident-training general hospitals. Midazolam as a premedicant and norepinephrine, phenylephrine, amrinone, esmolol, pentastarch were less used in hospitals without training program of residents. CONCLUSIONS: These results suggest that university hospitals and resident-training general hospitals didn't show difference in anesthestics or adjuvants but hospitals without training program of residents used less commonly isoflurane, atracurium, midazolam, ketamine, propofol, fentanyl, cardiovascular drugs and pentastarch.

This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

PURPOSE: To measure the size of normal corpus callosum in each portion using objective and reproducible method with MRI and evaluation of morphological change of corpus callosum by grade of hydrocephalus. MATERIALS AND METHODS: Midsagittal Tl-weighted MR imaging of the corpus callosum was investigated in 41 volunteers of normal Korean adults and 19 patients with hydrocephalus. Corpus callosum was measured for the anteroposterior length(A), height(B), and the thickness of genu(C), body (D), splenium(E), and the narrowest portion of body(F). And the analysis of morphology and signal intensity of the corpus callosum were also evaluated. Hydrocephalus was graded as mild, moderate, and severe, and comparision of thickness with normal corpus callosum in each portion was done. RESULTS: The mean length and height were 72.3mm, 28.6mm in male, and 70.7ram, 28.9mm in female. And the mean dimention for C, D, E, and F were 13.1 ram, 8ram, 13.2mm, 5.2ram in male, and 12.8mm, 7.5ram, 12.3 ram, 5mm in female. The morphology of normal corpus callosum was "hook" shaped on midline sagittal Tl-weighted image. Narrowing at posterior third portion of body were present on 30 cases(73.2%) and even in thickness of the body in 11 cases(26.8%). The signal intensity of the corpus callosum on midsagittal Tl-weighted spin echo image of normal cases was homogeneous hyperintense as compared with cerebral gray matter. In hydrocephalus, A and B were increased and other portions were decreased in thickhess. Genu and the narrowest portion of body showed significant difference of thickness according to the grade of hydrocephalus. CONCLUSION: The mean dimention of all portion of corpus callosum were larger in male than female except for callosal height but not significant statistically with the exception of splenium. Hydrocephalus lead to morphological change of the corpus callosum. Among the portion of corpus callosum, genu and the narrowest portion of the body were thought to be the most sensitive indicators of degree in hydrocephalus.

A clinical analysis was done on forty-five patients with fracture of the femoral neck, who have been admitted and treated at our orthopedic department during the period of 6 years, from January 1975 to December 1980. The following results were obtained: Age over 60 comprised 60% of the patients. Male to female ratio revealed no significant difference, being 21 to 24. However, with advancing age, female was affected more frequently than male. The major cause of injuries were “fall or slip down” occuring in 33 patients (73.3%) and “hit by car” in 12 patients (26.7%). Of the 39 patients in whom Garden's calssification of fracture could be applied. Stage II was the most common type occuring in 29 patients (75%), followed by Stage N in 6(15.4%), and Stage 5 in 4 (10%). Of the total 45 cases, forty patients were reduced and fixed with multiple Knowles pins and two patients with Jewett nail. Three patients with neglected treatment of the fracture for over 1 to 4 months were treated with primary replacement arthroplasty of the femur in two and total hip replacement in one. Fractures were united within 3 months in 10 patients (23%), 4 to 6 months in 19 patients (45.2%), and non-union in 2 patients. Relationship between accuracy of reduction using Gardens alignment index and develepment of avascular necrosis was evaluated. Of the 27 patients with reduction in the range of 155 180 in both frontal and lateral views, 3 patients were developed avascular necrosis, and of the 9 patients with reduction of less than 155 in frontal view or greater than 180 in lateral view, 4 patients were developed avascular necrosis.

This study was performed to evaluate the effects on hearing of video tape manufacturing workers exposed to organic solvents. The experimental groups included solvents exposed group 51 and unexposed group 57 workers. All workers was examined air and bone conduction sensitivity by pure tone audiometer. The mean age of solvents exposed group was 34.1 and nonexposed group was 35.8. The mean duration of solvents exposed group was 7.3years. High frequency hearing loss prevalence of both groups was 23.5% in the group exposed to organic solvents and 17.5% in nonexposed group. There is no statistical significants in the prevalence of high frequency hearing loss. According to comparison of mean auditory threshold value by frequencies, on the air conduction test, right was statistically significant in the 250, 500, 1000, 2000, 4000Hz, except 8000Hz. Left 250, 500, 1000Hz was statistically significant. On the bone conduction test, left250, both 500, 1000, 2000, 4000Hz, except right 250Hz, was statistically significant difference. Generally, auditory sensitivity threshold of the exposed group was higher than the nonexposed group.

PURPOSE: To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. MATERIALS AND METHOD: A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. RESULTS: Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. CONCLUSION: MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

Primary writing tremor is considered to be a task-specific tremor occurring when handwriting. We describe the clinical and electrophysiological features of 5 patients. Two of the patients had a family history of the tremor. Alcohol was effective in reducing the tremor in 3 of the patients. Two patients showed a co-contraction and three alternate contractions between agonist and antagonist muscles. The frequency of the tremors was 5 to 6 Hz. Primidone and propranolol were effective in reducing tremor. Considering the clinical and electrophysiological features, it is suggested that primary writing tremor might be a variant of essential tremor. (J Korean Neurol Assoc 19(1):52~55, 2001

BACKGROUND: Various types of dystonia may be associated with Parkinson's disease (PD). This dystonic phenomenon is sometimes observed in untreated parkinsonian patients. However, it more commonly emerges as a side effect to long term levodopa (LD) therapy. We studied several factors which influence the risk of the occurrence of LD-induced dystonia (LID) in patients with PD. The types and involved sites in LID were also studied. METHODS: Ninety-six patients diagnosed as PD were evaluated. We analyzed the contribution of several factors such as sex, age at onset of parkinsonian symptoms, disease durations, H & Y stages, average LD doses, LD durations, and types of initial symptoms (tremor vs non-tremor) to the occurrence of LID. The types of LID were divided into: wearing-off, morning-off, peak-dose, and diphasic groups. RESULTS: LID was observed in 29 patients (30.2%). Among the 29 patients with LID, 11 were categorized as wearing-off dystonia, 10 as morning-off, 6 as peak-dose, and 2 as diphasic. LID occurred in the feet or toes of 23 patients, upper extremities of 3, and in the heads or necks of 3. Sixteen patients had dystonias on the same side of their initial symptoms, 4 on the opposite side, and 6 on both sides. Among the several factors, the types of initial symptoms, average LD doses, LD durations, age at onset of parkinsonian symptoms, and H & Y stages were found to significantly contribute to the occurrence of LID. CONCLUSIONS: Dystonia often appeared as a side effect to anti-parkinsonian medications. Wearing-off dystonia was the most common type of LID. LID was commonly seen on the same side of initial symptoms. Initial parkinsonian symptoms were thought to be the most important contributing factor of LID.

Tonsillectomy is one of the most common procedures performed by an otorhinolaryngologist. Postoperative hemorrhage and dehydration are two of the most common complications, but glossopharyngeal neuralgia is an unusual complication encountered in tonsillectomy. Glossopharyngeal neuralgia is characterized by paroxysms of ipsilateral and severe lancinating pain occurring in the distribution of the nerve. The pain may be spontaneous or precipitated by a variety of actions that stimulate the region supplied by the glossopharyngeal nerve namely yawning, coughing, swallowing and talking. The proximity between the glossopharyngeal nerve and the tonsillar fossa suggests that dissection in the correct surgical plane during tonsillectomy is important for avoiding injury to the glossopharyngeal nerve. Glossopharyngeal neuralgia after tonsillectomy is induced by intraoperative cauterization, nerve compression or iatrogenic trauma. Management of glossopharyngeal neuralgia induced by tonsillectomy should be given a trial of anti-convulsant medication like carbamazepine or glossopharyngeal nerve resection. A case of glossopharyngeal neuralgia caused by tonsillectomy was experienced by a 29-year-old man, and this case was reported and its aetiology was discussed.
