Abstract We tried melatonin treatment in two patients with non-24 h sleep-wake syndrome, who did not respond to treatments by vitamin B12 , bright light therapy, or hypnotics. In one patient, melatonin 5–10 mg improved difficulty in falling asleep and in waking, although it failed to improve the sleep-wake rhythm. In another patient, melatonin 3 mg successfully changed the sleep-wake rhythm from free-running pattern to delayed sleep phase pattern. However, melatonin re-administration after a 4-month drug-free interval failed to improve his free-running sleep-wake rhythm. These results suggest that melatonin acted as a sleep inducer in one patient and as a phase setter in the other, although the effect on the latter patient was transient. 相似文献

A phase II study of mitoxantrone was performed in 24 patientswith non-small cell lung cancer (NSCLC). Mitoxantrone was administeredby intravenous drip infusion of 12 mg/m2 every three weeks.There were no responders among the 21 evaluable patients includingfive patients without prior therapy. The major hematologicaltoxic effect was leukocytopenia. Thrombocytopenia and decreasein hemoglobin were slight. A change in the electrocardiogramwas observed in one patient and one patient experienced cardiogenicshock. Mitoxantrone is not acceptable for the treatment of NSCLC becauseof its low antitumor activity, and careful observation is neededfor administration of this agent to patients with pre-existingrisk factors, such as prior anthracycline exposure, mediastinalradiation or underlying cardiovascular disease. 相似文献

We experienced a congenital complete atrioventricular block infant who was born from a Ro/SS-A antibody positive mother. Ro/SS-A antibody was also found in this baby which was presumed to be mediated by the maternal placenta. Temporary cardiac pacing was required at birth and pacemaker implantation was performed at 9 months. At 11 months of age, the baby fell into shock and experienced multiple organ failure because of diabetes mellitus-induced coma. The association between congenital complete heart block and the Ro/SS-A antibody is well known. However, the accompaniment of insulin-dependent diabetes mellitus has not been reported previously. As the Ro/SS-A antigen appears in the cytoplasm of many tissues, the possibility of an association between Ro/SS-A antibody and diabetes mellitus is difficult to deny. We report this rare case to draw attention to the possibility that babies who are born from an Ro/SS-A antibody positive mother may develop diabetes mellitus as well as congenital complete heart block. 相似文献

BACKGROUND: In Asian countries, glycerol solution that contains fructose (5%) is often used for management of brain edema. However, glycerol and fructose may cause severe hypoglycemia and metabolic acidosis in patients with fructose-1,6-bisphosphatase (FBPase) deficiency, even under stable conditions. The aim of the present study was to determine whether glycerol solution was used for brain edema during acute metabolic decompensation of hypoglycemia and metabolic acidosis in patients with unrecognized FBPase deficiency in Japan and to examine a long-term prognosis of the patients who had this kind of severe metabolic decompensation with or without glycerol therapy. METHODS: A retrospective study of 20 children with FBPase deficiency was conducted, based on their medical records. RESULTS: Six of the 20 children were given glycerol solution for the presence or possibility of brain edema during acute metabolic decompensation of hypoglycemia and metabolic acidosis; two of the six patients administered with glycerol were given dialysis. In four patients treated with glycerol alone without dialysis, two had no brain edema before glycerol administration but it developed later after the administration. These four patients treated with glycerol alone died or developed severe neurological complications. Fourteen patients who were not treated with glycerol solution had no brain edema and showed good prognosis. CONCLUSIONS: Glycerol solution, which contains fructose in Asian countries including Japan, should not be used as an osmotic agent for treatment of brain edema in patients who have hypoglycemia and retention-type metabolic acidosis, until FBPase deficiency is ruled out by measuring blood concentration of lactate. 相似文献

Abstract: Pulmonary surfactant (PS) is a mixture of several lipids (mainly phosphatidylcholine; PC) and four apoproteins (A, B, C and D). The classical hypothesis of PS transport suggests that PS is synthesized in the endoplasmic reticulum and transported to the lamellar body (LB) via the Golgi apparatus. However, recent studies have raised questions regarding this single route. This study examined, independently, the intracellular trafficking route of three different components of PS, that is, PC, SP-A and SP-B. Alveolar type II cells were isolated from Sprague–Dawley rats or Japanese white rabbits. The cells were cultured with either [3 H]choline or [35 S]methionine/cysteine with or without brefeldin A, which disassembles the Golgi apparatus. LB was purified from disintegrated cells with sucrose density gradient centrifugation. [3 H]PC was extracted from radiolabeled media, cells, and the LB fraction with Bligh–Dyer's method. [35 S]SP-A or [35 S]SP-B was immunoprecipitated from each sample with a specific antibody. [3 H]PC was transported and stored to the LB via a Golgi-independent pathway. [35 S]SP-A was transported to the Golgi apparatus, underwent glycosylation, and was then constitutively secreted. The secreted [35 S]SP-A was re-uptaken into the LB. [35 S]SP-B was transported and stored to the LB via the Golgi-dependent pathway. These results indicate that, rather than a single route, surfactant components take different pathways to reside in the LB. These different pathways may reflect the different nature and role of each surfactant component such as surface tension-lowering activity and innate host defense. 相似文献

AIM: We evaluated a prostate biopsy strategy for cancer detection using a computer simulation system with virtual needle biopsy for three-dimensional (3D) prostate models. METHODS: Two 3D prostate models with a volume of 25 cc or 50 cc were constructed from computed tomographic images of radical prostatectomy specimens. The peripheral zone (PZ) and transition zone (TZ) were arranged in the prostate models according to the anatomical information. Four thousand patterns of cancer lesions were automatically inserted into each prostate model with a proportion of 75% in PZ and 25% in TZ. Average hit rates (AHR) in prostate models were evaluated both with an increased number of biopsy cores and various angles of virtual needle biopsy. The influence of adding secondary tumors for hit rates was also evaluated. RESULTS: For both sizes, the laterally angled biopsy in 4-8 core biopsy schemes showed higher AHR than the vertical plane biopsy, while the vertical plane biopsy in 10-18 core biopsy schemes showed higher AHR than the laterally angled biopsy. A higher number of biopsy cores increased the AHR of secondary tumors. CONCLUSIONS: Our results suggest that it is important in prostate cancer detection to change the needle placement according to the number of biopsy cores and the size of the prostate. 相似文献

Abstract We examined polysomnography (PSG) and body temperature in a patient with delayed sleep phase syndrome who responded to phototherapy. The patient was a 31-year-old woman whose condition had slightly improved by a vitamin B12 administration. Phototherapy was administered to her in combination with the vitamin B12 medication, and this combined treatment successfully advanced her delayed sleep phase. On PSG, the regimen showed shortened sleep latency, decreased total sleep time and stages 1 and 2 sleep, and increased slow wave sleep. Phototherapy also improved temporal distribution of delta half-waves (0.5-2.0 Hz, 31 µV) as well as phase relationship between sleep and body temperature. 相似文献

Two cases of pseudomyxoma peritonei with high serum carcinoembryonicantigen (CEA) are reported. CEA levels in serum increased incorrelation with the accumulation of ascites. Systemic chemotherapywith anticancer agents such as 5-fluorouraciI (5-FU), cyclophosphamide,mitomycin C (MMC) and chromomycin Aa showed no effect on reducingeither the production of mucinous materials or the CEA level,but repeated intraperi-toneal instillation of large amountsof MMC reduced them in one case. In the other case, the CEAlevel returned to normal after removal of the tumor. These resultssuggest that CEA may be a useful indicator of the effect oftreatment and of the prognosis of pseudomyxoma peritonei. 相似文献

High-dose ifosfamide (one or two courses of 6 g/m2) with orwithout mesna was administered to 13 patients with advancednon-small cell lung cancer. The protective effect of 2-mercapto-ethanesulfonate (mesna) against the urotoxic side effects inducedby ifosfamide was examined by a randomized crossover trial.A significant reduction in the incidence of hematuria was observedin the patients receiving mesna. Macroscopic hematuria was observedin only one patient who received treatment with mesna versusseven patients treated with ifosfamide alone. Other symptoms,such as frequency and dysuria, tended to be diminished in thepatients receiving mesna, although the difference was not statisticallysignificant. Our results suggest that mesna is effective inpreventing or diminishing ifosfamide-induced hemorrhagic cystitis.Concomitant use of mesna should allow the administration ofa high dose of ifosfamide although more extensive studies areneeded to define the optimal dose and schedule of administrationof mesna to prevent or attenuate the hemorrhagic cystitis. 相似文献

Abstract The reliability and validity of the Japanese version of the Yale-Brown Obsessive-Compulsive Scale (JY-BOCS) were determined by 20 raters for 12 Japanese patients with obsessive compulsive disorder at four institutions. Interrater reliability for the total JY-BOCS score was excellent, and the intraclass correlation coefficient was high (ICC = 0.960). Internal consistency was also excellent (Cronbach's α= 0.889). Concurrent and discriminant validity of the JY-BOCS was examined by comparing the scores on the JY-BOCS with those on the Maudsley Obsessional Compulsive Inventory (MOCI) and scales for depression and anxiety. A slight correlation was found between scores on the JY-BOCS and MOCI, but no significant correlations were found between scores on the JY-BOCS and those on scales for depression or anxiety. 相似文献
