A 73-year-old male with a history of diabetes mellitus was admitted to our hospital for acute renal failure. An ultrasonogram revealed bilateral hydronephrosis, which worsened despite insertion of a bladder catheter. Nephrostomy catheters were positioned bilaterally, and Candida albicans was found in the urine culture. The patient was successfully treated with intermittent direct irrigation and i.v. antifungal agent therapy. Since 1977, approximately 50 cases of fungus balls or fungal bezoars in the urinary tract have been reported, but the majority of these cases have been characterized by unilateral ureteral or bladder involvement. Herein, we report a case of acute renal failure as a result of bilateral ureteral obstruction by Candida albicans fungus balls. 相似文献

Abstract This study was undertaken to elucidate the pathogenesis of the hydrocephalus and aqueductal stenosis induced by intracerebral mumps virus inoculation in suckling hamsters.
Mild ventricular dilatation became apparent after 5 days of inoculation. Focal denuding of the ependymal layer and subsequent aqueductal stenosis were observed by 14 days after inoculation. The virus antigen was detected not only in the ependymal cells and choroid plexus, but also in some neurons in the cerebral cortex, hippocampus, midbrain and cerebellum. In the cerebral aqueduct, the orderly arrangement of the cilialy clusters was destroyed on the 5th day after inoculation. After 10 days, proliferation of GFAP positive cells was noticed around the cerebral aqueduct and subsequently caused aqueductal stenosis. In the advanced state of hydrocephalus, the cerebellum was displaced downward and showed an elongated, atrophic and sleevelike structure similar to the Arnold-Chiari malformation. It was suggested that the extensive damage of the ependymal cilia may account for early ventricular dilatation, and subsequent aqueductal stenosis with glial proliferation is the main cause of the advanced hydrocephalus. It has not yet been determined whether the mumps virus can pass through the human placenta or not. If it can, however, our results strongly suggest that mumps virus infection in the human fetus will cause congenital hydrocephalus. 相似文献

The cerebellar Purkinje cells in the hemizygote of the macular mutant mouse contain numerous abnormal mitochondria which show a marked decrease in cytochrome c oxidase activity. Using histochemical methods we studied the activity of other mitochondrial enzymes, such as NADH diaphorase and succinic dehydrogenase, in the cerebellar cortex of this mutant mouse. Such activities were markedly increased in the Purkinje cells, especially in the soma and stem dendrite, from 10 days after birth in the hemizygote as compared with findings in normal littermates. These results were considered to be due to an increased number of abnormal mitochondria.Supported by the Research Grants nos. 2A-5-03 and 3B-1-04 for Nervous and Mental Disorders from the Ministry of Health and Welfare, and by Grant no. 04670492 of the Ministry of Education of Japanese Government 相似文献

Fourteen adult patients undergoing elective major abdominal surgery were divided into two groups. One group received epidural and general anesthesia (epidural group), and 20 ml of 0.125% bupivacaine and 2 mg of morphine were administered epidurally about 30 min before the end of the operation for post-anesthetic analgesia. The other group (control group) received general anesthesia alone with nitrous oxide, oxygen and enfiurane. Flow-directed pulmonary arterial and radial arterial catheters were inserted preoperatively, and hemodynamic, respiratory, neuroendocrine and metabolic variables were measured serially. The data were compared during anesthesia and the immediate post-anesthetic recovery period. In the control group, the plasma epinephrine level in the post-anesthetic recovery period increased about four times over the anesthetic period. Oxygen consumption was increased and mixed venous oxygen saturation was decreased significantly. There was a close linear correlation between oxygen consumption (Y) and plasma epinephrine (X) level: Y = 285.7X + 90.5 (P < 0.01, r = 0.72). On the other hand, plasma epinephrine, oxygen consumption and mixed venous oxygen saturation did not change significantly in the epidural group in the post-anesthetic recovery period. There was also a close linear correlation between oxygen consumption (Y) and oxygen delivery (X): Y = 0.22X -32.0 (P < 0.01, r = 0.89). We conclude that the surgical stress and anesthetic reversal may seriously influence neuroendocrine responses and subsequently increase plasma epinephrine. Tissue oxygenation and metabolic imbalance may occur due to the rapid increase of epinephrine in the postanesthetic recovery period. Epidural analgesia at this period may play a more important role and have a more favorable effect on the tissue metabolism. 相似文献

Objective : To investigate whether the haemodynamic effects of the standard 2-3 h blood transfusion increases the risk for intraventricular haemorrhage (IVH) and patent ductus arteriosus (PDA) in very low birthweight infants.
Methodology : In a randomized controlled study, haemodynamic changes using slow and rapid transfusion were compared. Twenty-seven very low birthweight infants were divided between 12 h ( n = 14) and 3 h ( n = 13) transfusion groups. Blood pressure, ejection fraction (EF), anterior cerebral artery pulsatility index (Pl), blood gases, serum electrolytes and haematocrit were measured pre- and post-transfusion. Infectious status was also monitored.
Results : Blood pressure (48.1/25.5 vs 55.7/30.2 mmHg) and EF (0.68 vs 0.73) increased significantly during rapid transfusion ( P >0.01) but remained stable with slow transfusion. Serum potassium, base excess and incidence of infection did not increase in either group.
Conclusions : Slow transfusion causes less haemodynamic disturbance than rapid transfusion, thereby preventing the potential risk for IVH and PDA. 相似文献

Rat‐bite fever identified by polymerase chain reaction detection of Streptobacillus moniliformis DNA
Daiki NAKAGOMI Nobuhiro DEGUCHI Akiko YAGASAKI Kazutoshi HARADA Naotaka SHIBAGAKI Masanobu KIMURA Koichi IMAOKA Shinji SHIMADA 《The Journal of dermatology》2008,35(10):667-670
A 74‐year‐old woman presented with erythema of the extremities, a high fever and arthralgia after being bitten by a rat. The patient was diagnosed as having rat‐bite fever based on the symptoms and clinical course, as well as the polymerase chain reaction detection of Streptobacillus moniliformis DNA in the crust of the bite site. This is the first case to be diagnosed using polymerase chain reaction on a crusted skin lesion specimen. Although clinical symptoms initially remitted with minocycline therapy, they relapsed. Subsequent administration of piperacillin sodium resulted in complete disappearance of the high fever and arthralgia. 相似文献

Abstract: We report a patient with an asymptomatic recurrent peptic ulcer occurring in the gastric tube after reconstruction for esophagectomy with a long follow-up. The patient is an 82-year-old male, who had undergone an esophagectomy for cancer, and a gastric tube was used for esophageal replacement at the age of 77 years. A follow-up study using endoscopic examination revealed an active peptic ulcer in the gastric tube one year after the operation, ulcer scar formation 9 weeks after H2 receptor antagonist medication, and recurrence of the ulcer about 3 years after quitting the medication. The recurrent active ulcer has disappeared after re-administration of H2 receptor antagonist. Helicobacter pylori has not been detected, although eradication has not been per formed. It is suggested that high acidity might play a part in the pathogenesis of ulcer formation despite the vagotomy. Since a peptic ulcer in the gastric tube can potentially cause serious complications including perforation and hemorrhage, we have to bear in mind not only recurrence of the cancer but also gastric tube ulceration in the follow-up survey after esophagectomy, to facilitate early detection of ulcer and effective treat ment.
