BACKGROUND: The aim of this study was to clarify the clinical characteristics of facial nerve palsy and the frequency of varicella-zoster virus association in Japanese children, retrospectively. METHODS: The subjects were 30 facial nerve palsy patients less than 15 years old, treated in the Department of Pediatrics, Kawasaki Medical School Hospital, Okayama, Japan, during the last 10 years. RESULTS: The male/female and right/left ratios were 16/14 and 16/13, respectively. The patients included 21 cases (70%) of Bell's palsy, four cases (13%) due to otitis media, three cases (10%) of Ramsay Hunt syndrome and two cases (7%) due to birth trauma. There were six cases of zoster sine herpete among the Bell's palsy cases. CONCLUSION: Varicella-zoster virus-associated facial palsy was found in nine (36%) of the 25 patients examined. Zoster sine herpete was more frequently encountered in children than adults. Ramsay Hunt syndrome was found in school-age children and zoster sine herpete was often found in preschool children. The period of recovery was fast for facial nerve palsy due to acute otitis media, which occurred within 23 months of age, after myringotomy and administration of antibiotics. 相似文献

Eosinophils are characterized by several functional properties, such as chemotaxis, adhesion, superoxide anion production, and degranulation. In this article, we have studied the role of bacterial ingestion by eosinophils in comparison with that by neutrophils. Eosinophils and neutrophils were purified by using the Percoll gradient method followed by selection with CD16‐coated immunomagnetic beads and centrifugation through a Ficoll‐Hypaque gradient combined with dextran sedimentation, respectively. Both cells were preincubated with anti‐FcγRIIa mAb (CD32 mAb), anti‐FcγRIIIb mAb (CD16 mAb), anti‐CR3 (CD11b mAb), or anti‐CR1 (CD35 mAb) before being examined for phagocytosis of opsonized heat‐killed Staphylococcus aureus (S. aureus). Phagocytosis and production of hydrogen peroxide were simultaneously measured by flow cytometry using S. aureus labeled with propidium iodide and stained with 2′,7′‐dichlorofluorescein diacetate. Eosinophils showed significantly lower activity than neutrophils in both phagocytosis and hydrogen peroxide production. Phagocytosis by both cells was decreased by heat‐inactivated serum. Phagocytosis by neutrophils was significantly inhibited by CD16 mAb and CD32 mAb, whereas that by eosinophils was only inhibited by CD35 mAb. Whereas the mechanism of phagocytosis by neutrophils was mediated by CD16 and CD32, that of eosinophils was modulated by complement receptor 1 (CD35). 相似文献

A pacemaker lead fracture in the left subclavian vein was caused by compression of the clavicle and the first rib; subsequent coil elongation at the same site on the right side was observed in the replacement lead in a patient with thoracic outlet syndrome. Venography showed narrowing of the subclavian vein at the site where the lead abnormalities were observed. This case illustrates that a lead in the subclavian vein can be easily damaged when a patient has thoracic outlet syndrome. 相似文献

Effect of glycyrrhizin on lysis of hepatocyte membranes induced by anti-liver cell membrane antibody 总被引:6,自引:0,他引:6

Studies were made on why glycyrrhizin injection decreases the plasma aspartate aminotransferase (AST) and alanine aminotransferase activities in patients with chronic hepatitis.1 For this, rat hepatocytes were isolated, and incubated with antibody raised against rat liver cell membranes, and the effect of glycyrrhizin on their release of transaminase was investigated. Isolated rat hepatocytes released AST on incubation with anti-liver cell antibody in the presence of complement. At this time, their endogenous phospholipase A2 activity was increased. Cultured hepatocytes also released the transaminase in the presence of venom phospholipase A2. Glycyrrhizin suppressed the release of transaminase in the presence of either anti-liver cell membrane antibody or phospholipase A2. These results suggest that antibody treatment raised the phospholipase A2 activity in liver cell membranes, resulting in release of transaminases, and that glycyrrhizin suppressed this increase in phospholipase A2 activity and so inhibited the release of transaminase. 相似文献

Background: It has been reported that Alzheimer’s disease (AD) patients with Lewy pathology have a shorter time from a given baseline to institutionalization than those with AD alone. Taking the clinical distinction between dementia with Lewy bodies (DLB) and AD into consideration, the previous findings may indicate the possibility that the clinical characteristics of DLB patients have an influence on early institutionalization. This study was carried out to clarify whether there are any differences in the symptoms that required institutionalization between patients with DLB and those with AD. Methods: Hospital records and standardized data forms completed at admission to a residential care facility were reviewed to assess the profiles in all cases with autopsy‐confirmed diagnoses for correct differential diagnosis. We examined functional, cognitive and symptomatic conditions at admission to a residential care facility of 18 DLB and 35 AD patients whose diagnoses were confirmed by autopsy. The examinations were conducted using the Gottfries‐Bråne‐Steen (GBS) scale and cognitive tests, and the results were compared between the two groups of patients. Results: Hallucinations, impaired wakefulness, disturbance of ADL and emotional disturbance, common clinical features compatible with DLB, were more frequently observed in DLB patients than in AD patients (P < 0.05). Moreover, DLB patients had higher scores on cognitive tests than did AD patients at admission to a residential care facility (P < 0.05). Conclusion: The distinctive clinical features at admission to a residential care facility may indicate that the reasons for the necessity of institutionalization are different between DLB and AD, and that the interventions specific to DLB patients and their families would be necessary to prevent or postpone institutionalization. 相似文献

Changes in work performances in obstructive sleep apnea patients after dental appliance therapy 总被引:2,自引:0,他引:2
HIDEKI ARAI HISAKAZU FURUTA KAZUTO KOSAKA REIZO KANEDA YOSHIFUMI KOSHINO JO SANO SHIGEHIRO KUMAGAI ETSUHIDE YAMAMOTO 《Psychiatry and clinical neurosciences》1998,52(2):224-225
Abstract The effects of dental appliances on work performances of obstructive sleep apnea syndrome (OSAS) is not well examined. This study evaluated the polysomnographic and psychological findings before and after therapy. Nine patients were diagnosed OSAS by nocturnal polysomnography. The psychological battery was performed from 13:00 to 14:00, which consisted of Uchida-Kraepelin psychodiagnostic test (U-K's test) and Bourdon's cancellation test (Bourdon's test). Approximately 3 months after the treatment, the examinations were performed. Apnea and desaturation index decreased significantly after the therapy. In addition, sleep architecture improved after the therapy compared with that before the therapy. Dysfunction of task performances, such as mean level of work amounts in U-K's test, mean error, mean performance time and mean deviation in Bourdon's test improved after therapy. We conclude that dental appliances therapy is effective not only to apnea but also to work performance in OSAS. 相似文献

A morphological approach to cell dynamics is usually difficult, since routine preparative techniques for electron microscopy always induce artifacts due to cessation of the blood supply into organs. An in vivo cryotechnique followed by the freeze-substitution method probably reduces such problems. It was applied for examining the pulmonary alveoli of BALB/c mice in vivo. The following ultrastructural features were revealed. (1) A surfactant layer provided a continuous covering to the alveolar epithelium. (2) Pleural epithelial cells, alveolar cells and endothelial cells contained many small vesicles and pits. In the alveolar epithelium, they were often localised near microtubules. (3) Typical lamellar structures in large alveolar epithelial cells were rarely detected. (4) Circulating erythrocytes with various shapes were observed in branching blood capillaries. (5) A close association between erythrocytes and the endothelium was seen at the peripheral alveolar septum. Such ultrastructural arrangements may be appropriate for the physiological functions of the pulmonary alveoli, such as exchanges of gases or materials in vivo. 相似文献
