A 17-year-old boy with high fever, headache, and neck stiffness was admitted to our hospital. Spinal fluid showed a protein level of 215 mg/dL with myelin basic protein (579 pg/mL), 347/ microl cells (330 mononuclear cells), and a glucose level of 53 mg/dL. One week later, urinary retention, flaccid paraplegia, and sensory disturbance below the 10th thoracic level developed. MRI of the spinal cord revealed swelling and T2-high intensity area in the cord at the 11th and 12th thoracic level. Although high-dose of methylprednisolone was administered, consciousness disturbance and respiratory failure that required mechanical ventilation occurred. Bilateral abducens nerve palsy, nystagmus, and flaccid tetraparesis also occurred. Brain MRI revealed T2-high intensity area in the midbrain and pons. Nerve conduction study showed diminished amplitudes and prolonged latencies or absence of F waves. The patient was administered a combination of intravenous immunoglobulin and a high-dose of methylprednisolone. He showed improvement within one week after the treatment. Two weeks later, he recovered from respiratory failure and weakness of the upper limbs. He remained paraplegic, but gradually improved and was able to walk with support one and a half years later. We suggest the combination therapy of intravenous immunoglobulin and a high-dose of methylprednisolone is effective for patients with combined ADEM and peripheral neuropathy. 相似文献

Lmmunohistochemical analyses were made of the superoxide dismutases (Mn-SOD and CuiZn-SOD) in biopsied muscles from 7 patients with mitochondrial encephalomyopathies that included mitochondrial encephalomyopathy, lactic acidosis and strokelike episodes (MELAS), and chronic progressive external ophthalmoplegia (CPEO). Mn-SOD mainly was present in the subsarcolemmal region, but it also was found in a coarsely granular, reticular, or diffuse pattern of staining within the muscle fibers. These Mn-SOD-positive fibers corresponded almost completely to the ragged-red fibers. The immunoreaction for CuiZn-SOD was weakly positive in some of the muscle fibers positive for Mn-SOD. In CPEO, Mn-SOD-positive fibers predominantly showed decreased cytochrome c oxidase (COX) activity. In MELAS, Mn-SOD-positive fibers tended to be stained deeply for COX although a few were COX-negative. These findings suggest that Mn-SOD-positive fibers can be used to make a differential diagnosis between CPEO and MELAS and that in mitochondrial encephalomyopathies Mn-SOD in the raggedred fibers may protect against oxidative stress. © John Wiley & Sons, Inc. 相似文献

We have investigated the clinical significance of urinary tissue polypeptide antigen (TPA) as a tumor marker for urothelial cancers. Urinary TPA levels were determined by the immunoradiometric assay of Prolifigen TPA Kit "Daiichi"-II in 486 healthy controls and 1835 patients with various diseases including 526 with urothelial cancers and 140 with prostatic cancer. The mean value of urinary TPA was 199 +/- 213 (1SD)U/1 in 486 healthy controls. 95% of them having a level below 600 U/l. Therefore, 600 U/l was applied as a cut-off level. Positive rates of urothelial cancers and reactivated prostatic cancer were 57.6% (148 of 248 cases) and 45.5% (5 of 11 cases) respectively. On the other hand, the false positive rate of most urological benign diseases was only about 20% except for the acute stage of urinary tract infections and upper urinary tract stones with hydronephrosis. There was no significant difference in the positive rate between urinary TPA level and urinary cytology in urothelial cancers. The combination of both tests raised the positive rate to 73.1%. Therefore, urinary TPA may be useful in the monitoring of urothelial cancers, and the combination of urinary TPA and urinary cytology may increase the diagnostic accuracy. 相似文献

In 1980, extracorporeal shock wave lithotripsy (ESWL) was incorporated as a nonsurgical method of stone removal in the cases of nephrolithiasis and rapidly found worldwide acceptance. Several devices commonly designated "second generation" lithotripters vs "first generation" Dornier HM3 are now under experimental or clinical trial. We report our clinical experience of ESWL using a Siemens Lithostar and compared it with that obtained using a Dornier HM3. One hundred patients were treated during the period of April through October, 1986 using an HM3, and 100 other patients were treated using a Lithostar from April to August, 1988. More cases were treated with a Lithostar than with a HM3. Nearly 10% of all patients treated by ESWL required additional therapeutic approaches (excepted ureteral stent) either with HM3 or Lithostar. However, in the cases of ureteral stone, with the Lithostar more cases required adjuvant procedures (TUL) than HM3. Significantly more shock waves were needed with Lithostar than HM3 for complete fragmentation of the same size of renal and ureteral stones. The stone-free rate during a one month period after ESWL was nearly the same for HM3 and Lithostar (HM3: 84.3%, Lithostar: 83.5%). Lithostar is a multifunctional lithotriptor which has most of the advantages required by the lithotripter. 相似文献

The time-course of changes of basal and amphetamine (AMPH)-induced locomotor and stereotypic activities in adult male Wistar rats after a single ribavirin injection was studied. In the first set of experiments, 10, 20 or 30 mg ribavirin/kg body weight (b.w.) were injected i.p. to rats and their basal motor activities were recorded every 10 min for 2 h and compared with those of saline-treated controls. In the second set of experiments, the animals were pretreated with ribavirin and 20 min later i.p. injected with AMPH (1.5 mg/kg b.w.). The controls received AMPH 20 min after the saline injection. Motor activity was recorded after the first injection and until 120 min after AMPH administration. Ribavirin did not significantly affect the time-course of either basal locomotor or stereotypic activities. Pretreatment with any of the applied ribavirin doses decreased the AMPH-induced hyperlocomotor response. However, the most pronounced effect was observed with ribavirin doses of 20 mg/kg and 30 mg/kg when administered during the first 10 min and 30 min after the AMPH injection respectively. In contrast, the stereotypic activities of these animals were only slightly changed. These results indicate a different susceptibility of regions in the basal ganglia to ribavirin. 相似文献

We encountered a surgical case of middle aortic syndrome (MAS) in a 56-year-old man who had resistant hypertension. Computed tomography showed severe stenosis of the abdominal aorta from below the superior mesenteric artery to above the inferior mesenteric artery. Although bilateral renal artery stenosis was confirmed, renal function was within normal limits. A 10-mm vascular prosthetic graft was used to perform a descending aorta to left external iliac artery bypass. His hypertension was well controlled without medication. This extra-anatomic bypass may be a simple and useful approach for treating MAS if it is not necessary to reconstruct the renal artery or visceral artery. 相似文献

Aims/IntroductionThis study aimed to reveal lifestyle changes and their impact on glycemic control and weight control in patients with diabetes during the coronavirus disease 2019 (COVID‐19) pandemic in Japan.Materials and MethodsWe retrospectively analyzed 1,402 outpatients with diabetes at a clinic in Osaka, Japan, who responded to an interview sheet regarding lifestyle changes during the COVID‐19 pandemic between 28 March and 30 May 2020. The association of lifestyle changes with hemoglobin A1c (HbA1c) and weight changes from February to May 2020 was investigated using the linear regression model. We also investigated the association with clinically important change of HbA1c (by ≥0.3%) and bodyweight (by ≥3%), using the cumulative link model.ResultsLeisure time and other outside physical activities were decreased in one‐quarter of patients during the COVID‐19 pandemic, whereas the amount of meals and snacks was decreased and increased in approximately 10%, respectively. The change in leisure time physical activities was inversely associated with HbA1c and weight changes, whereas the quantitative change of meals with the decline in eating out and that of snacks were positively associated with HbA1c and weight changes (all P < 0.05). The quantitative change of meals without the decline in eating out was also positively associated with weight change (P = 0.012). The cumulative link model for clinically important HbA1c and weight change showed broadly similar associations, except for that between snacks and bodyweight (P = 0.15).ConclusionsA considerable number of outpatients with diabetes experienced lifestyle changes during the COVID‐19 pandemic. The lifestyle changes were associated with HbA1c and weight changes. 相似文献
