BACKGROUND: The value of serum prostate-specific antigen (PSA) screening was examined to detect prostate cancer in men receiving hemodialysis. METHODS: Forty-one male patients age 60-95 (median age, 70 years) receiving hemodialysis were investigated for PSA levels. We set the cut-off point at 4 ng/mL (the usual reference range). Digital rectal examination (DRE) and transrectal ultrasonography (TRUS) of the prostate were performed in patients whose PSA was more than 4 ng/mL and/or who expected further examination of the prostate. When prostate cancer was suspected, biopsy of the prostate was performed. In patients with prostate cancer, magnetic resonance imaging, computed tomography and bone scintigraphy were performed to diagnose the clinical stage. RESULTS: The mean serum level of PSA was 2.10 +/- 0.49 ng/mL. In this screening study, four of 41 men required further examinations for prostate cancer. Two of four refused further examinations. The other two were diagnosed with prostate cancer. The incidence of prostate cancer was at least 5% in our hemodialysis patients. One man, whose clinical stage was T2aN0M0, was treated with radical retropubic prostatectomy. Another man, whose clinical stage was T2bN0M0, was treated with luteinizing hormone-releasing hormone analogue. CONCLUSION: In our preliminary study, prostate cancer screening with PSA was useful for the early detection of prostate cancer in hemodialysis patients. If possible, DRE and TRUS should be performed in conjunction with PSA tests. 相似文献

Posterior stabilization is a common surgical procedure, which aims for rigid stabilization by facet fusion. Facet non-union has a potential risk of the screw loosening and malalignment. Although some authors have reported the influencing factors about screw loosening in the lumbar spine, there are few reports about the risk factor contributing to the facet non-union in the cervical spine. In all, 22 patients (78 facets and 122 screws) with degenerative cervical kyphosis or spondylolisthesis who underwent decompression and lateral mass screw (LMS) fixation were analyzed. Age, gender, smoking, bone mineral density (BMD), the degree of facet decortication with bone packing, and screw loosening were investigated as risk factors contributing to the facet non-union at each segmental fused level. Facet fusion rate was 85.9% (67/78 facets) and the incidence of loosening was 4.9% (6/122 screws, 4 patients). Insufficient facet decortication with bone packing is a significant risk factor of facet non-union (p <0.05, odds ratio: 26.5). All six loosened screws were associated with bony non-union of the facet and were located in the uppermost or lowermost vertebrae. Comparing loosened screws and stable screws, the average maximal insertional screw torque (MIT) was 9.8 cNm and 39.5 cNm, respectively (p <0.05). Additionally, the length of the stable screws was significantly longer versus the loosened screws (p <0.05). Lower MIT and shorter screw length located near the ends of the lateral mass may predict loosening, which can lead to facet non-union. Sufficient facet decortication with bone packing is one of the important factors contributing to the facet fusion. 相似文献

Background and objective: Bronchiolitis obliterans (BO) has been reported to develop following ingestion of Sauropus androgynus (SA), a leafy shrub distributed in Southeast Asia. Little is known about direct effects of SA on airway resident cells or haematopoietic cells in vitro. Identification of the SA component responsible for the development of BO would be an important key to elucidate its mechanism. We sought to elucidate the direct effects of SA on airway resident cells or haematopoietic cells and identify the SA element responsible for the pathogenesis of BO. Methods: SA dry powder was partitioned into fractions by solvent extraction. Human and murine monocytic cells, epithelial cells and endothelial cells were cultured with SA solution or fractions eluted from SA. We also investigated the effect of SA in vivo using a murine BO syndrome (BOS) model. Results: The aqueous fraction of SA induced significant increases of inflammatory cytokine and chemokine production from monocytic lineage cells. This fraction also induced significant apoptosis of endothelial cells and enhanced intraluminal obstructive fibrosis in allogeneic trachea allograft in the murine BOS model. We found individual differences in tumour necrosis factor α (TNF‐α) production from monocytes of healthy controls stimulated by this aqueous fraction of SA, whereas it induced high‐level TNF‐α production from monocytes of patients with SA‐induced BO. Conclusions: These results suggest that an aqueous fraction of SA may be responsible for the pathogenesis of BO. 相似文献

Abstract Four all-night polysomnograms of a 39-year-old male patient with non-24 h sleep-wake syndrome were recorded. We analysed electroencephalograms (EEG) with the power spectrum method and the wave pattern recognition analysis of Fujimori. The EEC of the rest waking condition showed normal patterns. High-voltage diffuse alpha band waves were observed in sleep stages 2, 3 and 4. The integrated area of the alpha band waves in the analysis epochs showed a strong positive correlation to the delta hand components in the power spectrum of the same epoch during sleep (correlation coefficients r = 0.762–0.815). Alpha hand waves during sleep were clearly different from the alpha waves in the rest waking condition, with respect to slower peak frequency and the frontal dominant voltage distribution. 相似文献

The reasons for morphological changes of urinary red blood cells (RBC) in patients with glomerulonephritis are still controversial. In order to evaluate the importance of mechanical damage by the glomerular basement membrane (GBM), we examined urinary RBC taken from the patients with two different diseases which have characteristic GBM changes. Urinary RBC taken from 20 patients with Alport syndrome and nine with thin GBM disease were examined using a scanning electron microscope. Nineteen out of the 20 patients (95.0%) with Alport syndrome showed ‘glomerular type’, while five of the nine patients (55.6%) with thin GBM disease showed ‘glomerular type’. These results suggest that more complicated GBM abnormalities cause more severe RBC distortion. Therefore, we conclude that mechanical damage by the GBM may be the major factor in dysmorphism of urinary RBC. 相似文献

The purpose of this study was to evaluate the effect of interruptionof the descending supraspinal sympathetic outflow on heart ratecontrol during exposures to chemical stimuli. We investigatedthe heart rate responses to progressive isocapnic hypoxia andhyperoxic hypercapnia using the rebreathing technique and quantifiedthe relationship between heart rate (HR), oxygen saturation(SaO2), alveolar PCO2 (PACO2), and minute ventilation (VE) in16 chronic tetraplegic subjects with low cervical spinal cordtransection. The HR responses were determined from the linearslopes of HR on SaO2 and HR on PACO2. We found that mean restingheart rate was within normal range; 66 ±3 (SEM) beatsmin1. HR increased as oxygenation fell or CO2 tensionrose. The mean tetraplegic HR/SaO2 was 0.83 ± 0.14 beatsmin1 per 1% fall in SaO2 and that of HR/PACO2 was 0.30± 0.13 beats min1 per mmHG rise in PACO2. TheHR and VE responses to either hypoxia or hypercapnia were relatedin the tetraplegic subjects. We conclude that the stimulatoryHR reponses to chemical stimuli are not suppressed by cervicalspinal cord transection. Thus, the descending sympathetic activitydoes not underlie the HR acceleration by chemical stimuli. 相似文献

Abstract Two cases of sleep disordered-breathing in climacteric were reported. Polysomnography including esophageal pressure (Pes) measurement was performed. Case 1 was diagnosed as upper airway resistance syndrome. Case 2 was diagnosed as obstructive sleep apnea syndrome, while many episodes of upper airway resistance also existed. Hormone replacement therapy improved clinical symptoms, and in case 1, Pes nadir was improved but incidence of arousals which was induced by breathing disturbances was not significantly changed. Sleep disordered-breathing should be suspected as a cause of sleep disorder even in females, especially in climacteric age. Pes measurement and evaluation of arousals is required. Hormone replacement therapy may release the upper airway resistance. 相似文献

OBJECTIVE: To assess the clinical efficacy of endoscope-assisted minilaparotomic radical retropubic prostatectomy (EAM-RRP) compared with conventional radical retropubic prostatectomy (cRRP). METHODS: From September 2001 to December 2003, 30 patients with localized prostate cancer were treated by EAM-RRP. The surgical manipulation was performed through the wound with thoracoscopic assistance, using standard surgical instruments. In all cases, 800 mL of blood was collected from the patient for autotransfusion. For both EAM-RRP and cRRP, the internal iliac and obturator lymph nodes were dissected before the prostate removal. Clinical indicators such as operation time, blood loss, and duration of postoperative urine incontinence were analysed in the two groups. RESULTS: The postoperative period before ambulation and the duration of postoperative urine incontinence were significantly shorter after EAM-RRP than after cRRP, while no significant difference was found in operation time, blood loss, and duration of urethral catheterization. None of the cases required allotransfusion. CONCLUSION: EAM-RRP, which had a shorter postoperative period before ambulation and continence, is considered a safe and useful technique for radical prostatectomy. 相似文献

Aims:
To evaluate the immunohistochemistry using an anti-mitochondria antibody in the investigation of various oncocytic lesions of the salivary glands.
Methods and results:
Ten cases of adenolymphoma (Warthin's tumour) and one case each of benign oncocytoma and oncocytic carcinoma of the salivary glands were examined. Normal salivary glands were also tested. They were investigated immunohistochemically using mouse monoclonal antibody against human mitochondria. In normal salivary glands, epithelial cells of the striated ducts showed a thick linear immunoreactivity, which corresponded well to the intracytoplasmic distribution pattern of mitochondria. In addition, a small number of swollen epithelial cells showing an intense, finely granular immunoreactivity in the cytoplasm were scattered in the ductal system and acini ('oncocytic metaplasia'). Almost all neoplastic cells involved in adenolymphoma, benign oncocytoma, and oncocytic carcinoma showed an intense, finely granular immunoreactivity in the cytoplasm.
Conclusions:
Immunohistochemistry using the anti-mitochondria antibody proved to be a highly sensitive and specific method for light microscopic identification of mitochondria and superior to routine H & E or PTAH stain especially in the detection of isolated oncocytic cells. 相似文献

Background and objective: Patients with COPD often experience restriction in their activities of daily living (ADL) due to dyspnoea. This type of restriction is unique to patients with COPD and cannot be adequately evaluated by the generic ADL scales. This study developed an ADL scale (the Activity of Daily Living Dyspnoea scale (ADL-D scale)) for patients with COPD and investigated its validity and internal consistency.
Methods: Patients with stable COPD were recruited and completed a pilot 26-item questionnaire. Patients also performed the Incremental Shuttle Walk Test (ISWT), and completed the St. George's Respiratory Questionnaire (SGRQ) and Medical Research Council (MRC) dyspnoea grade.
Results: There were 83 male participants who completed the pilot questionnaire. Following the pilot, eight items that were not undertaken by the majority of subjects, and three items judged to be of low clinical importance by physical therapists were removed from the questionnaire. The final ADL-D scale contained 15 items. Scores obtained with the ADL-D scale were significantly correlated with the MRC dyspnoea grades, distance walked on the ISWT and SGRQ scores. The ADL-D scores were significantly different across the five grades of the MRC dyspnoea grade. The ADL-D scale showed high consistency (Chronbach's α coefficient of 0.96).
Conclusions: The ADL-D scale is a useful scale for assessing impairments in ADL in Japanese male patients with COPD. 相似文献
