Abstract Although respiration in trained canines is well investigated, the process of preparing dogs has not been described in any great detail. Moreover, their daytime patterns of sleep and wakefulness during 1 or 2 h of electroencephalogram (EEG) and electrocardiogram (ECG) recordings are not clear. Therefore, we describe the process of selecting and training dogs, in which we recorded EEG and ECG in the laboratory. First, 14 of 1242 dogs dealt with over a 1 year period were chosen. They were trained for 2 h to lie quietly and to sleep in the laboratory; this training procedure was repeated 152 times. Three dogs were then selected and a permanent tracheostomy was performed in one. Finally, EEG and ECG were recorded with the bipolar fine needle electrodes; respiration was recorded simultaneously through a tube inserted to a tracheostomy in one dog. Wakefulness, slow wave sleep (SWS) and rapid eye movement (REM) sleep (REMS) were identified according to the EEG pattern and on the basis of the behavioral criteria. Recordings were performed 12 or 13 times in each dog. Complete sleep cycles, including wakefulness, SWS and REMS in this sequence, were observed 3.9–4.1 times. The mean duration of SWS was 2.2–4.4 min and that of REMS was 3.5–4.6 min. The REMS latency was 33.9–41.8 min. Fluctuation of heart rate with respiration, termed respiratory sinus arrhythmia, was noted in the ECG. Heart beat increased with inspiration and decreased with expiration. The present study demonstrates how to select and train sleeping dogs and shows their undisturbed daytime sleep and wakefulness patterns. 相似文献

We report a case of creeping disease treated successfully with ivermectin. A 46-year-old man presented with a 1-month history of pruriginous linear erythema on his right thigh after a visit to Indonesia. Although he had no history of eating raw fish or meat, he walked along the river and in the jungle without wearing shoes. Creeping disease caused by animal hookworm was strongly suspected. The presence of parasite larvae was not confirmed in biopsied skin specimens. In enzyme-linked immunosorbent assay, serum samples were negative for binding to hookworm antigens, including Ancylostoma canium , Necator americanus and Gnathostoma doloresi . He was treated with a single 12 mg oral dose (200 µg/kg) of ivermectin. The eruption and pruritus resolved within a few days after the administration and did not relapse. 相似文献

Clonal and non-clonal karyotypically abnormal cells in haemophagocytic lymphohistiocytosis 总被引:1,自引:0,他引:1
YASUHIKO KANEKO NOBUO MASEKI MASAHARU SAKURAI MASARU IDO YUKIKO TSDNEMATSU SHUKI MIZUTANI TATSUYA HATTORI HIROYUKI SHIMIZU HARUHIKO EGUCHI TOSHIAKI OKA MUNENORI MIYAKE YASUO HORIKOSHI TAIZAN SUCHI 《British journal of haematology》1995,90(1):48-55
We studied chromosomes in bone marrow (BM) or peripheral blood cells of nine patients with haemophagocytic lymphohistiocytosis (HLH); three of them had a family history of HLH and four others underwent concurrent Epstein-Barr virus (EBV) infection. In addition to a large population of normal mitotic cells, karyotypically abnormal clonal cells were found in two patients, abnormal clonal cells and a nonclonal (single) abnormal cell in one, and nonclonal abnormal cells in three. All the six patients with chromosome abnormalities died of progressive disease; one of them also had EBV infection and EBV-associated clonal proliferation. Two of three patients with EBV infection and only normal mitotic cells in BM completely recovered from the disease.
Although HLH did not show histological and/or haema-tological evidence of a neoplastic disease, clonal chromosome abnormalities and the fatal clinical outcome found in some of the patients suggest that the disease may be heterogenous and include malignancy. HLH patients with karyotypically abnormal clonal cells in BM should warrant more intensive chemotherapy than that presently being applied to them and should be considered as candidates for BM transplantation. 相似文献

A 39-year old woman, with a pancreatic arteriovenous malformation (AVM) which ruptured into the pancreatic duct, was treated successfully with distal pancreatectomy and splenectomy. Histological examinations revealed an AVM with extravasation into the pancreatic ducts. A review of the cases reported to date emphasizes the importance of physical signs, individual histories and angiographic studies for early diagnosis and surgery. 相似文献

TAKEUCHI, T., et al. : A Case of a Short-Coupled Variant of Torsades De Pointes with Electrical Storm. This case report describes a short-coupled variant of Torsades de Pointes with a characteristic ECG pattern consisting of a prominent J wave in leads V3 –V6 , in which an electrical storm was evoked with autonomic receptor stimulation and a blockade test. The patient's frequent VF attacks were triggered by short-coupled premature ventricular contractions with a right bundle branch block morphology and left-axis deviation, and were suppressed by deep sedation followed by a combination therapy using verapamil and mexiletine. Interestingly, with the use of those drugs, the prominent J wave diminished. The mechanism underlying this syndrome is discussed. (PACE 2003; 26[Pt. I]:632–636) 相似文献

PURPOSE: We evaluated retrospectively health-related quality of life (HRQOL) after radical prostatectomy (RP) in Japanese men with localized prostate cancer. METHODS: The study was based on self-reported HRQOL of 280 patients. Patients were divided into seven groups: time 0 (T0), baseline before operation; T1, 1-3 months after RP; T2, 4-6 months after RP; T3, 7-12 months after RP; T4, 13-24 months after RP; T5, 25-36 months after RP; and T6, more than 36 months after RP. We measured the general and disease-specific HRQOL using the RAND 36-item Health Survey 1.0 (SF-36) and the University of California, Los Angeles Prostate Cancer Index (UCLA PCI). RESULTS: The general HRQOL of the postoperative groups was assessed by SF-36. The postoperative groups showed almost the same or higher scores than those of the baseline group. Urinary function scores decreased substantially after surgery. In contrast, there was no difference in urinary bother between the baseline and postoperative groups. Sexual function deteriorated substantially in all postoperative groups. Similarly, the sexual bother score significantly deteriorated after RP. The sexual bother score of men aged 65-years or younger was significantly worse than that of their counterparts in the T1-2 groups. CONCLUSION: Despite reports of problems with sexual activity and urinary continence, general HRQOL was mostly unaffected by RP. Although there was a substantial decrease in urinary function, recovery from urinary bother was rapid. Since the deterioration of sexual function was marked through the postoperative period, careful attention should be paid to this issue during preoperative counseling, especially for younger patients. 相似文献

Prognosis of the middle-aged and aged patients with obstructive sleep apnea syndrome 总被引:4,自引:0,他引:4
AKIKO NODA PhD TAMOTSU OKADA MD PhD FUMIHIKO YASUMA MD PhD TOSHIKAZU SOBUE MD PhD NOBUO NAKASHIMA MD PhD MITSUHIRO YOKOTA MD PhD FACC 《Psychiatry and clinical neurosciences》1998,52(1):79-85
Abstract The long-term natural course of obstructive sleep apnea syndrome (OSAS) is studied in order to determine whether severity of nocturnal oxygen desaturation associated with apnea/hypopnea, body mass index (BMI), and hypertension influence survival in young (<40 years), middle-aged (40–64 years), and aged (65 years) using a questionnaire survey. One hundred and forty-eight patients with OSAS aged 17–78 years (136 men, 12 women, mean 52.0±12.3 yean), who were diagnosed by standard polysomnography (PSG) between 1983 and 1993, participated in the study. The survey revealed 15 deaths and 101 survivors; 32 subjects could not be located. The survival rate was 71.4% (95% confidence interval:55.6–87.2%). The survival rate in patients with OSAS was significantly lower than that in the age and sex-adjusted control Japanese population (87.6%). In the young group, only one death (a 19–year-old woman) occurred unexpectedly during sleep. The patient showed an apnea/hypopnea index (AHI) of 33 per h and the length of time that the nocturnal oxygen saturation (SaO2) fell below 90% (time of SaO2 < 90%) of 205 min. The survival rate in middle-aged patients with OSAS was significantly lower than that in the age and sex-adjusted control Japanese population (79.2 vs 91.0%), but this pattern was not seen among the aged. Time of SaO2 <90% was significantly longer in the middle-aged patients than in the aged patients, but AHI did not differ between the two groups. Moreover, it was significantly correlated with AHI in middle-aged patients, but not in the aged patients. The survival rate was significantly lower in patients with hypertension than in the patients without such complications in the middle-aged group (57.9 vs 90.4%). Cox proportional-hazard regression model including age, hypertension, BMI, AHI, lowest SaO2, and time of SaO2 <90% showed that hypertension was only significantly associated with lower survival rate in total group and middle-aged patients, but not in the young or aged patients. The prognosis in patients with OSAS may differ among the generations. The prognosis in the middle-aged population may depend on the role of OSAS on the complications of hypertension or severity of oxygen desaturation, but not on AHI only. 相似文献
