The anxiety disorders make up one of the most common groups of psychiatric disorders. Anxiety is an alerting signal ; it warns of impending danger and enables a person to take measures to deal with a threat. Three major schools of psychological theory-psychoanalytic, behavioral, and existential-have contributed theories about the causes of anxiety. Many drugs are effective in managing distressing signs and symptoms associated with anxiety disorders. As the symptoms are controlled by medication, patients are reassured and develop confidence that they will not be incapacitated by the disorder. Benzodiazepines are useful in panic disorder, phobias, and agitation. In general, benzodiazepines act as hypnotics at high doses and as anxiolytics or sedatives at low doses. The benzodiazepines have become the sedative-hypnotic drugs of first choice because they have a higher therapeutic index and significantly less abuse potential than do many of other sedative-hypnotics. The most common adverse effect of benzodiazepines is drowsiness. Some patients also experience dizziness and ataxia. The most serious adverse effects of benzodiazepines occur when other sedative substances are taken concurrently. When benzodiazepines are used for long periods, they usually cause significant tolerance, dependence, or withdrawal effects. Overdoses with benzodiazepines alone have a predictably favorable outcome. The benzodiazepines should be started at a low dosage, and the patient should be informed about the drug’s sedative properties and abuse potential. Serotonin-specific reuptake inhibitors (SSRIs) have a much more favorable profile of adverse effects and have significantly broadened the horizon for pharmacological treatment of anxiety disorder. Three fourths of patients experience no adverse effects at low starting doses, and doses may be increased relatively rapidly in these patients. In the remaining one fourth of patients, most of the SSRIs’ adverse effects appear within the first 1 to 2 weeks, and they generally subside or resolve spontaneously if the drugs are continued at the same dose.

Ten cases of unstable spine were treated with various surgical procedures under control of Halo apparatus and following results wen obtained. 1. Six cases of unstable cervical spine were treated with Halo apparatus and were able to obtain solid fusion for permanent stability. 2. Three cases of tuberculous kyphosis were corrected with halo-pelvic hoop on, and were able to obtain mean correction angle of 42 (65%) with little danger. 3. With halo on, staged operations such as anterior and posterior osteotomy, gradual distraction, anterior and posterior fusion of the spine for correcting deformity were carried out securely. 4. Average duration of halo application was eight weeks, no more twelve weeks, and there was no irreversible complication with halo apparatus per se.

The authors have reviewed 71 cases (70 patients) of the ankle fractures that were treated through the admission in Orthopedic Department, Paik Foundation Hospital, from June 1972 to April 1978. The average duration of the follow-up waa 15 months. The summary of the results were as follows; 1. Of the 71 cases, male was 54 cases and female 17 cases. The average age of the patients was 32. 2. The main cause of the injuries was traffic accident, and the other causes were sliding down and falling from a height, industrial accident, and sports injury in order. 3. By the classification of Lauge-Hansen, the pronation-external rotation and,supination-adduction types were commoner than the other types. 4. Open reduction was performed in 48 cases, and closed reduction in 23 cases. 5. The average duration of the cast immobilization after the closed reduction was 8 weeks, and that of the open reduction was 6 weeks. 6. The result of the treatment was better in those cases of the open reduction than that of, the closed reduction. 7. The good clinical results could be achieved by obtaining the anatomical position of the talus in the mortise and the reduction was achieved more satisfactorily when the key role of the lateral malleolus in complete reduction was well understood.

Bacterial meningitis results in significant neurologic dificits despite in spite of much effort in the treatment of the disease. This study was performed to determine the incidence of caustive organisms and to correlate between the organisms and computed tomographic (CT) findings with clinical outcome of bacterial meningitis in newborns and infants. We analyzed the brain CT and clinical records of 15 infants who had been diagnosed as bactrial meningitis by CSF culture. We found that the most common organisms were Group B streptococcus in neonates withou no neurologic complications in all but one and Hemophilus influenza in infants whose clinical outomes were poor in all except one. CT findings related with poor prognosis in this study were cerebral edema, basal cistermal obliteration & enhancement, and cerebral infarction on initial CT and ventriculomegaly on follow-up CT. We concluded that CT diagnosed intracranial complications of bacterial meningitis well and could contributed to better treatment of bacterial meningitis.

The composition of triglycerides of the axillary sebaceous glands in 10 patient, with osmidrosis and 10 patients with hyperhidrosis was analyzed by high pressure liquid chromatography. Sebaceous glands were isolated and dissected by Kellum's method, and lipids were extracted by Folchs method. Individual triglycerides were separated by high pressure liquid chromatography and fatty acid composition of triglycerides was analyzed by gas-liquid chromatography. A number of individual triglycerides were identified: Fraction 1 consisted of dimyristoarachidonin, dilinoleioarachidonin, and myristol inoleioarachidonin, fraction 2 was trilinolein, fraction 3 was dilinoleioolein, fraction 4 was dilinoleiopalmitin, fraction 5 consisted of dioleiolinolein, dipalmitolinoleiri, and palmitooleilinolein. In osmidrosis patients, cornpositions of fraction 1, 2, 3, 4, and 5 were 5, 4%. 18.5% 29.5% 32.0% 14.1% of total triglycerides, respectively. In hyperhidrosis patients, cornpositions of fraction 1, 2, '3, 4, and 5 were,5, 9%, 20. 6%, 30. 9% 32. 1%, 14. 5% of total triglycericles, resectively. There were no differences in composition of triglycerides of sekaceous glands between osmidrosis patients and hyperhidrosis patients and hyperhi.frosis patients.

Testicular involvement in male patients with leprosy is well documented and may be associated with impotence, sterility and gynecomastia. Testicular histology shows atrophy of the seminiferous tubules with hypertropy and clumping of Leydig cells and hyalinization of the small and medium sized vessels. The hormonal functions of the testes have been studied by a number of workers, usually in patients with testicular atrophy and gynecomastia. In these particular patients, androgens are generally diminished while gonadotropins are increased. The pathogenesis of testicular damage is uncertain, though Wall and Wright(1974) found that testicular germinal cell antibodies were present in 75% of lepromatous, and postulated that :autoirnmunity, Erythema Nodosum Leprosum imrnune complex damage and direct invasion by Mycobacterium leprae may all be contributory.

OBJECTIVES: Major depression is associated with an increased risk of cardiovascular mortality. One possible explanation for this association is that major depression influences autonomic neurocardiac regulation. However, previous studies on the relationship between heart rate variability (HRV) and major depression have revealed conflicting results. The purpose of this study is to clarify that major depressive patients compared to healthy controls show a reduction in HRV as an expression of reduced modulation of vagal activity to the heart. METHODS: According to DSM-IV, the time and frequency domain HRV indices (5-min resting study) of 30 patients with major de-pressive disorder were compared with those of 30 healthy controls. Standardized HRV tests enable quantitative estimation of auto-nomic nervous system function. RESULTS: After controlling for age and gender, subjects with major depression showed a higher heart rate and significantly lower modulation of cardiovagal activity compared to controls. The total power (TP) band, very low frequency (VLF: 0.003-0.04 Hz) band, low frequency (LF: 0.04-0.15 Hz) band, and high frequency (HF: 0.15-0.4 Hz) band were significantly reduced in subjects with major depression compared to control subjects. CONCLUSION: Patients with major depression may suffer from functional disturbances in the interaction between the sympathetic and parasympathetic autonomic systems.
