Ambulatory BP monitoring was performed in a patients with pheochromocytoma before and after removal of the tumor. Before surgery, it did not show any significant diurnal variation. But, after surgery the diurnal variation was restored.

Purpose: The purpose of this study was to evaluate the mortality of patients over eighty years old with femoral neck fractures that have been treated with bipolar endoprostheses. Materials and Methods: We retrospectively studied 37 patients out of a total of 83, who suffered from hip fractures and were treated with surgery from 2000 through December 2004. We attempted to distinguish the differences between the 8 patients who died (Group A) and the 29 patients who lived (Group B). The variables that we analyzed, were: age, sex, operative time, the time period from admission to surgery, the time period from admission to discharge, the ASA score, and any medical comorbidities. Results: In Group A, 2 patients died within 1 month, 2 died between 1 and 6 months, 1 died between 6 and 12 months, and 3 died after 1 year. There were statistical differences between Group A and Group B with respect to two variables: the time period from admission to, and medical comorbidities. Conclusion: There were significant correlations with an increase in the mortality rate among patients with lung disease, female patients in general, and delays in surgery. Therefore, particular care should be paid to patients with these variables.

Journal of the Korean Neurological Association 1998;16(2):237-240
BACKGROUND AND SIGNIFICANCE: Parkinsoinsm is characterized by clinical symptoms of igidity, bradykinesia, tremor, and gait disturbance. There are many causes of secondary parkinsonism. Hypocalcemia associated with hypoparathyrodism is a rare metabolic cause of secondary parkinsonism. We experienced a case presenting reversible secondary parkinsonism caused by hypocalcemia associated with idiopathic hypoparathyroidism. CASE: A 35-year-old woman was admitted to our hospital because of generalized edema. She had been diagnosed as nephrotic syndrome for 1 year. During admission, slurred speech suddenly developed and hypocalcemia was founded. With replacement of calcium and dialysis, these symptom were improving. However, she complained of slowly progressive gait disturbance. On examination, she had parkinsonian features including masked face, slurred speech, rigidity of all extremities, bradykinesia, gait disturbance with short step, and stooped posture. Laboratory studies showed hypocalcemia, primary hypoparathyroidism, normal thyroid and parathyroid scan. Brain CT and MRI revealed normal. She was diagnosed as secondary parkinsonism following hypocalcemia associated with idiopathic hypoparathyroidism. She was started on levodopa and bromocriptine, and parkinsonian features slowly improved. One month later, she was fully recovered from parkinsonian features, and then levodopa and bromocriptine were discontinued. COMMENT: We report a case of reversible secondary parkinsonism caused by hypocalcemia with idiopathic hypoparathyroidism.

9.Roles of Ca2+ activated K+ conductances on spontaneous firing patterns of isolated rat medial vestibular nucleus neurons.

To investigate the contributions of intrinsic membrane properties to the spontaneous activity of medial vestibular nucleus (MVN) neurons, we assessed the effects of blocking large and small calcium-activated potassium channels by means of patch clamp recordings. Almost all the MVN neurons recorded in neonatal (P13~P17) rat were shown to have either a single deep after-hyperpolarization (AHP; type A cells), or an early fast and a delayed slow AHP (type B cells). Among the recorded MVN cells, immature action potential shapes were found. Immature type A cell showed single uniform AHP and immature B cell showed a lack of the early fast AHP, and the delayed AHP was separated from the repolarization phase of the spike by a period of isopotentiality. Application of apamin and charybdotoxin (CTX), which selectively block the small and large calcium-activated potassium channels, respectively, resulted in significant changes in spontaneous firings. In both type A and type B cells, CTX (20 nM) resulted in a significant increase in spike frequency but did not induce bursting activity. By contrast, apamin (300 nM) selectively abolished the delayed slow AHP and induced bursting activity in type B cells. Apamin had no effect on the spike frequency of type A cells. These data suggest that there are differential roles of apamin and CTX sensitive potassium conductances in spontaneous firing patterns of MVN neurons, and these conductances are important in regulating the intrinsic rhythmicity and excitability.

BACKGROUND: This study purposed to survey the fit rate of respirators by person and by product through conducting a qualitative fit test of high-efficiency respirators; moreover, this study also tests for differences in the fit rates determined by the qualitative fit tests with an increase in the number of the types of respirators tested. METHODS: The subjects of this study were 30 healthcare personnel who had passed a sensitivity test. The fit test of high-efficiency respirators was conducted using FT10 (3M Co., USA), an experimental tool used for performing the qualitative fit test of high-efficiency respirators, and three types of high-efficiency respirators - 1860, PFR95, and N7000 - were tested. RESULTS: The qualitative fit test was performed for the three types of high-efficiency respirators and the fit rate of the respirators that the subjects had been using previously was 43.3%; however, the probability that one or more of the three types of high-efficiency respirators would fit the subjects increased to 83.3%, and this increase was statistically significant (P<0.05). The difference in the fit rates of the three types of high-efficiency respirator types was not statistically significant; however, the differences in the satisfaction of and preference for the different respirator products were all statistically significant (P<0.05). CONCLUSION: Healthcare personnel are using ill-fitting respirators and a qualitative fit test should be performed to improve the fit of their respirator. In the qualitative fit test performed for the high-efficiency respirators, the fit rate increased with the increase in the variety of respirator types. Thus, a large variety of respirators should be made available to increase the fit rate of high-efficiency respirators for healthcare personnel.
