Alcohol dementia and alcohol delirium in aged alcoholics 总被引:1,自引:0,他引:1
HIROO KASAHARA MD AKIHIDE KARASAWA MD TAKAYOSHI ARIYASU MD TATSUYA THUKAHARA MD JOUJI SATOU MD SADANOBU USHIJIMA MD 《Psychiatry and clinical neurosciences》1996,50(3):115-124
Abstract In the present study, 126 alcoholics aged 60 years or older were compared with 104 alcoholics aged 35–45 years. No dementia was found in the younger group, whereas 62.7% of the aged patients had dementia; the dementia being irreversible in 32.9% of such patients. Cases of so-called alcohol dementia excluding organic brain diseases accounted for 42.1%. The percentage of aged alcoholics having dementia increased with age, being far beyond the frequency of senile dementia in the general aged. Among various physical complications, hepatic injury and myocardiopathy were more frequent in the aged alcoholics than in general aged people, suggesting that hypertension, myocardiopathy and hepatic injury underlie the manifestation of dementia. There was no case of dementia attributable to the direct effect of alcohol distinctly exceeding the effects of various physical factors. Problem behaviors characteristic of the aged group included 'being soaked in drink' and being inebriated, showing no correlation with the presence or absence of dementia. There was no significant difference in frequency of delirium between the aged group and the younger group. However, in aged alcoholics delirium tended to continue for a longer period during abstinence and was more likely to occur even during non-abstinence. A similar trend was found in aged alcoholics with dementia compared with those without dementia. 相似文献

Aim: It is a common belief that terminally ill cancer patients have a reduced tissue tolerance that makes them more susceptible than other patients to developing pressure ulcers. However, the actual changes at the tissue level caused by pressure loading in terminally ill cancer patients are unknown, so we examined the relationship between the macroscopic and microscopic features of the tissues of such patients with and without pressure ulcers. Methods: The pressure ulcers of four patients were macroscopically evaluated until the time of death, after which informed consent of the family was obtained to examine the underlying skin tissue histologically. Samples were taken from several sites on the abdomen, which does not experience pressure loading, and from the sacral area. Two of the subjects had no observable pressure ulcers and the other two had a stage I and stage II (National Pressure Ulcer Advisory Panel classification) pressure ulcer, respectively. The samples were processed, stained and examined by using light and transmission electron microscopy. Results: The non‐pressure ulcer samples showed degenerated keratinocytes, leakage of erythrocytes from the capillaries in the dermal papillae, vascular inflammation, and edema. The samples from the stage I and II ulcers had the additional changes of dilated capillaries and vascular inflammation in and around the wound area. Conclusion: Terminally ill cancer patients have damaged skin tissue and inflammation that are not evident by macroscopic examination. 相似文献

BACKGROUND: Cryoablation is a treatment option for some patients with small exophytic lesions of the kidney. The purpose of this study is to determine the feasibility, safety, and intermediate-term treatment outcome of percutaneous cryoablation of renal cell carcinoma guided by horizontal open magnetic resonance imaging (MRI). METHODS: We prospectively used cryoablation to treat 13 patients with radiographically confirmed enhancing small, solid renal tumors (< or =4.8 cm). An argon gas-based cryoablation system was used. One to four cryoprobes with 2 or 3-mm diameters were placed percutaneously into the tumor under local anaesthesia and MRI guidance. Ice ball dimensions were monitored by 2-D MR images. Double freeze-thaw cycles were conducted throughout the procedure. After successful cryoablation, patients were followed on a regular basis to evaluate the treatment's clinical outcome. RESULTS: Median follow up from time of procedure is 35 months (range, 28-42). In all cases the entire procedure was accomplished without significant morbidity or complications. A mild retroperitoneal hematoma, which subsided spontaneously, was noted in one patient. Follow-up dynamic computed tomography (CT) at 3 months after operation confirmed the absence of enhancement in resolved tumor masses for 11 of 13 cases. None of these 11 patients had clinical evidence of recurrent disease at last follow up. The remaining two patients had lesions with some enhanced areas. Subsequent partial nephrectomy histologically confirmed the presence of vital tumor in, respectively, the center and the periphery of the residual masses. One of these patients developed multiple lung and ipsilateral adrenal metastases 13 months after surgical resection. CONCLUSIONS: Percutaneous cryoablation of small renal cell carcinomas under horizontal open MRI guidance appears to be safe and feasible. An intermediate-term follow up continues to demonstrate efficacy in most patients; however, a few patients experience incomplete ablation with risk of treatment failure. The ideal candidates for this procedure still need to be determined in longer follow up with diligent observation. 相似文献

The loss of haemolytic activity in sera during storage at low temperature (the cold activation of complement) was observed in 136 of 184 (74%) patients with chronic liver disease associated with hepatitis C virus (HCV) infection. This was more frequent than observed in the three of 40 (8%) patients with chronic hepatitis B (P < 0.001) or none in 43 normal controls (P < 0.001). Of 103 patients with chronic hepatitis C who had completed a full course of recombinant interferon-α2a therapy (total dose: 516×106U), 40 responded completely and 21 responded partially, as judged by the normalization or decrease of alanine aminotransferase levels 6 months after the completion of therapy; 42 patients did not respond at all. The cold activation of complement persisted in five (13%) complete responders, less often than in 33 (79%) non-responders (P < 0.001). At the completion of interferon therapy, the cold activation of complement persisted in 12 of 54 patients despite the normalization of alanine aminotransferase. Spontaneous exacerbation of hepatitis occurred in seven of 12 (58%) patients with cold activation, which was more frequent than in the four of 42 patients (10%) without it (P < 0.01). The cold activation of complement disappeared along with the loss of HCV-RNA in five of six responders during the 6 month period after the completion of interferon therapy, while both cold activation and HCV-RNA persisted in all eight non-responders. These results indicate that the cold activation of complement may be useful as a marker of HCV viraemia for monitoring the response to interferon in patients with HCV infection. 相似文献

The efficacy and safety of postoperative analgesia with continuous epidural infusion of either morphine or fentanyl in combination with bupivacaine were evaluated in 85 patients, ASA physical status I or II, undergoing thoracic and/or upper abdominal surgery. Patients were treated with one of the combinations for 48 h after surgery. The morphine/bupivacaine group (MB; n = 45) received morphine at the rate of 0.2 mg h-1 , and bupivacaine at the rate of 10 mg h-1 for the first 24 h or 5 mg h-1 for the second 24 h; the fentanyl/bupivacaine group (FB; n = 40) received fentanyl at the rate of 20 μg–h-1 , and bupivacaine at the rate of 10 mg h-1 for the first 24 h or 5 mg h-1 for the second 24 h. The degree of pain relief assessed by the visual pain scale and the modified Prince Henry pain scale was satisfactory in most patients in both groups. In group MB 74% and in group FB 76% of patients did not need any supplementary analgesics. No significant differences were observed between the groups in assessment of pain. The incidence of hypotension ( P < 0.05) and pruritus ( P < 0.05) was higher in group MB than in group FB. None of the patients developed respiratory depression in either group. 相似文献

BACKGROUND: A pressure-flow study, although a slightly invasive procedure, can evaluate bladder outlet obstruction and detrusor contractility. This study was conducted in men with a non-enlarged prostate to determine the cause of urinary disturbance by less invasive examinations that might eventually replace pressure-flow study. METHODS: Thirty-six men with lower urinary tract symptoms were enrolled. Their prostate volume, estimated by transrectal ultrasonography, was less than 20 mL. All patients were examined using pressure-flow study, free-flowmetry, transrectal ultrasonography, prostate specific antigen and an interview using the International Prostate Symptom Score and Quality of Life Index. With determination of the cause for urinary disturbance, parameters that correlated with outflow obstruction or impaired detrusor contractility were sought. RESULTS: Twenty-one (60%) of the 36 men were judged as having outflow obstruction, and 16 of these 21 men had normal detrusor function. Impaired detrusor contractility was observed in 17 men. Only three of these 17 men had no outflow obstruction. Four patients had an unstable bladder. All these four had normal detrusor contractility, but had outflow obstruction. Among the parameters examined, only the maximum flow rate in a flow metrogram (Qmax) correlated significantly with the degree of outflow obstruction (P = 0.04). The positive predictive value of Qmax for outflow obstruction was 65% at a flow rate of less than 10 mL/s, and 100% at that of less than 5 mL/s. No parameter correlated with detrusor contractility. CONCLUSION: The only parameter that was a clear indicator of outflow obstruction was Qmax. Other indicators of detrusor contractility should be sought. 相似文献
