A total of 342 patients with acute myocardial infarction who were admitted to a coronary care unit are reviewed to assess the results of early mobilization and discharge. The mean duration of admission was 8·4 days and 89% of the survivors were discharged from hospital by the tenth day. The inpatient mortality was 15·5%. An additional 6·7% died during the six weeks'' follow-up period, giving a total mortality of 22·2%. Altogether, 7·6% of patients were readmitted. Venous thromboembolic phenomena occurred in 3·5% during the inpatient period. Of patients who were eligible 62% were back at work five months after their myocardial infarction. We think the results justify a short hospital admission period for acute myocardial infarction.  相似文献

A prospective study of hepatitis in 20 dialysis units in the United Kingdom showed that the number of units with outbreaks increased from one in 1968 to three in 1969 and the overall attack rate rose from 1·7 to 5·3% in patients and from 0·5 to 1·3% in staff.In July 1969 a pilot study of patients'' sera showed that all of the outbreaks were associated with Australia (Au) antigen. Au antigen was not detected in the unaffected units or in one unit in which there were several patients with abnormal liver function.In January 1970 systematic prospective testing for Au antigen was begun. Au antigen was detected in single patients in five more of the 20 units. The transfer of the affected patients to isolation for dialysis seemed to prevent the spread of infection in the units. The incidence of hepatitis in 1970 was 5·6% in patients and 0·4% in staff.  相似文献

In this controlled multicentre trial treatment with either streptokinase or heparin was allocated at random to patients suffering from myocardial infarction of less than 24 hours'' duration. Treatment with either drug was standardized and lasted for 24 hours. A total of 764 patients entered the trial; 34 patient charts were rejected (including all 28 charts from one centre) because of data failure. On retrospective analysis of the 730 remaining patients the two groups were found to have been comparable at the start.The total hospital mortality was 18·5% of 373 patients allotted to streptokinase treatment and 26·3% of 357 given herapin. The mortality after infusion (24 hours) was 10·6% of 340 patients treated with streptokinase and 17·8% of 320 given herapin (P=0·011). Reinfarction in hospital after the 24-hour period of infusion occurred significantly less often in patients treated with streptokinase (P=0·036). Bleeding from puncture sites and pyrexia occurred more frequently during streptokinase treatment.After exclusion of those patients whose diagnosis was unconfirmed on retrospective assessment, the total hospital mortality rate was 19·0% of 357 patients treated with streptokinase and 27·4% of 339 treated with heparin (P=0·011). These results indicate that in recent myocardial infarction streptokinase was superior to heparin in reducing mortality and reinfarction rate during an average period of six weeks in hospital.  相似文献

The emergency surgical work load created by patients aged 80 and over in a district hospital was assessed and the results of treatment examined. Over one year 248 patients aged 80 or over were admitted as emergencies, and the overall mortality rate was 21·8%. When terminal disease was excluded mortality rate was 12·5%. These elderly patients had an average length of stay in the acute surgical ward of 14·7 days compared with a mean of 8·4 days for all patients, and all but seven patients were discharged to their original place of referral.Elderly patients do exacerbate the bed shortage in acute surgical wards because they tend to stay longer than younger patients, but these elderly surgical patients imposed only a small load on the inpatient geriatric services, as 78% were discharged straight to their own homes and a further 17% went home after a period on the surgical convalescent wards.  相似文献

A five-bedded coronary care unit has been set up within a general medical ward without the provision of extra medical or nursing staff. During 30 months 1,000 patients were admitted. Sixty-three developed cardiac arrest; 28 were resuscitated successfully initially; and 18 were eventually discharged. The corresponding figures for the 28 patients with ventricular fibrillation treated by direct current defibrillation were 20 and 12 respectively. The mortality rate during the first three days (the usual length of stay in the unit) was 8·9% compared with 9·7% after transfer to the general ward. It is suggested that these results are comparable with those from more highly staffed purpose-built units.  相似文献

A “no refusal” coronary care service (for one year) was offered to a selected sample of 10 general practices (total list 74,657). The patients were admitted to a three-bedded unit in Doncaster Royal Infirmary and data were collected to enable estimation of the size of unit necessary to serve the whole population in the area (census estimate 268,560; total G.P. list 315,811). This estimation was based on:1. The frequency of admission to hospital of suspected acute myocardial infarction in one year, estimated at 978 from the total population.2. The average duration of stay in the unit, which was 2·45 days.3. The distribution of observed occupancy was approximately Poissonian.From these the average expected bed occupancy was calculated as 6·56 and reference to probability tables gave the frequency of overload for different numbers of beds provided. The incidence of acute myocardial infarction in the area is estimated at 275 per 100,000 per annum, on calculations based on the practice list size, and at 323 per 100,000 per annum, on calculations based on census figures.  相似文献

The management and outcome of 258 severe attacks of ulcerative colitis from 1952 to 1969 has been reviewed. If remission did not occur during an initial course of intensive medical treatment, including administration of corticosteroids, operation (generally ileostomy with proctocolectomy or subtotal colectomy) was performed. This took place some 12 to 17 days after admission as a rule during the years 1952-63, but usually within five to seven days from 1964 to 1969.Roughly half the attacks underwent spontaneous remission during the two periods, but the medical mortality was 4·8% in the former and 0·7% in the latter, the operative mortality 20·0 and 7·0%, and the overall mortality 11·3 and 4.5% respectively. The lowering of the mortality was particularly striking in severe first attacks and in severe attacks in patients over 60 years of age.Perforation of the colon was found in 21 cases, or nearly 20% of 112 patients coming to operation during attacks, being commoner in the first period (32·5%) than in the second (11·1%). The immediate mortality of all such operations was 11·6%; in cases with perforation it was 28·6%.Acute colonic dilatation was observed in 28 cases. All but one were treated by emergency colectomy, at which the colon was noted to be perforated in 11. The mortality of these operations was 18·5%.Follow-up of the 140 patients who survived without coming to operation during their attacks shows that 52 (37·1%) subsequently underwent surgical treatment either during further attacks or electively.Though all 258 attacks were thought at the time to be due to ordinary ulcerative colitis, subsequent pathological examination of operative specimens derived from 98 patients who came to urgent or subsequent operation during the 1964-9 period revealed that the lesion in the large bowel was Crohn''s disease in 17 instances.  相似文献

The role of peripheral vascular tone in the development of hypotension induced by dialysis was investigated in eight patients undergoing haemodialysis with acetate or bicarbonate buffered fluid. Each patient had two sessions of dialysis with acetate fluid and two with bicarbonate fluid in the order acetate, bicarbonate, bicarbonate, acetate or bicarbonate, acetate, acetate, bicarbonate. Mean arterial blood pressure fell at a mean rate of 3·9 mm Hg/hour during dialysis with acetate fluid and 1·4 mm Hg/hour during dialysis with bicarbonate fluid. The rate of fall was significantly greater during dialysis with acetate fluid compared with bicarbonate fluid. Heart rate increased by a mean rate of 2·6 beats/min/hour during dialysis with both acetate and bicarbonate fluid. Vascular resistance in the forearm increased at a rate of 3·6 units/hour during dialysis with acetate fluid and 4·5 units/hour during dialysis with bicarbonate fluid, but the venous bed of the forearm dilated. The index of venous tone rose at a mean rate of 0·23 ml/100 dl over 40 mm Hg/hour during dialysis with acetate fluid and 0·20 ml/dl over 40 mm Hg/hour during dialysis with bicarbonate fluid.Inappropriate peripheral venodilatation may be important in the development of hypotension induced by dialysis.  相似文献

Sixty four patients were referred for cardiac transplantation from a single cardiac team at this hospital between October 1984 and December 1986. Of these patients, 33 were referred for urgent transplantation, all of whom required intensive treatment in hospital with intravenous infusions of cardiac drugs, intra-aortic balloon counterpulsation, peritoneal dialysis, ventilation, or any combination of these to sustain life. Of these 33 patients, six died while awaiting transplantation, one was removed from the waiting list for a transplant, and 26 received cardiac transplants. There were five deaths within 24 hours of operation and one death 10 days after the operation. Twenty of those who had surgery had a successful outcome of transplantation, but there was one late death 10 weeks postoperatively and a further death 31 months after surgery. Eighteen patients were alive and well 10 to 33 months (mean 19·4 months) after transplantation, with an overall survival rate after surgery of 69%.Provided that surgery can be performed before renal failure has progressed such that renal transplantation is necessary, the results are excellent (surgical survival 85·5%) and, we believe, justify the expenditure and staffing requirements necessary to treat these terminally ill patients.  相似文献

Fat embolism was assessed at necropsy and correlated with clinical findings in the patients who died among 854 with fractured hips admitted to hospital between 1967 and August 1971. Sixteen cases of clinical importance were found, eight of which were judged to have been fatal or to have seriously contributed to death. Frequencies were as follows: 2·4 to 3·3% among 424 patients with subcapital fractures; 0·7 to 0·8% in the 405 with trochanteric fractures; 4·1 to 7% among subjects treated without operation, representing 30% of those who died within seven days; and 0·9 to 1·1% among patients treated by pinning, nailing, or nail-plating. The higher frequency in the conservatively treated group is probably related to selection of poor-risk subjects. Fat embolism was found in 6·8 to 8·0% of those with subcapital fractures treated by primary Thompson''s arthroplasty which utilizes acrylic cement, and in none of those given Moore''s prostheses for which cement is not used. Study of a larger group after Moore''s prosthesis is required to establish its lack of special risk. Fat embolism accounted for all the deaths within seven days of Thompson''s arthroplasty and for most within 14 days; it was clearly related to surgery in some cases.A possible explanation of the hazard of Thompson''s arthroplasty is that fat globule entry is enhanced by a rise of intramedullary pressure due to proximal occlusion of the reamed marrow cavity. A controlled trial of the effect of venting the marrow cavity on the frequency of fat embolism is warranted. It is possible that the acrylic monomer may also contribute to venous entry of medullary fat. The higher-age group of those with subcapital fractures and associated chronic cardiac and pulmonary disease might make them more susceptible to fat embolization than those in whom arthroplasty is also carried out for chronic hip disease.  相似文献

During the active phase of viral hepatitis urinary folate loss was found to be 8·0 to 48·3 (mean 31·1) μg./day, compared with a normal urinary folate excretion of 0·1 to 18·0 (mean 9·5) μg./day. In cirrhosis and cardiac failure with congestive hepatomegaly the corresponding values were 25·8 to 55·0 (mean 35·7) μg./day and 2·5 to 61·6 (mean 26·9) μg./day, respectively. Urinary folate loss may be a significant factor in the aetiology of folate deficiency of chronic liver disease, particularly when dietary intake is poor.After prolonged dialysis in Visking casing urinary folate was almost totally dialysable, but an appreciable fraction of serum folate was not, even after 72 hours. The dialysable (free) folate fraction of serum and urine disappeared maximally during the first six hours'' dialysis, and was virtually cleared after 24 hours'' dialysis; clearance curves in normal individuals and in liver disease were comparable. The non-dialysable serum folate fraction was of similar magnitude in all subjects studied, in spite of marked variation in total folate, and probably represented protein-bound folate.  相似文献

A new balloon catheter for women with a flexible urethral portion that conforms to the shape of the closed urethra was tested. In sheep control catheters caused epithelial destruction, which was absent with the conformable catheter. A 12 week crossover trial compared control catheters in 52 long stay geriatric patients. Eighty two out of 91 conformable catheters were rated as comfortable compared with 68 of 87 control (p=0·006). The average length of time in situ was 15·9 days for the conformable catheter compared with 12·9 days for the control (p=0·001). The average number of bypasses a week with the conformable catheter was 1·1 compared with 1·3 for the control; this difference was not significant. Examination of 249 used catheters showed significantly fewer with intraluminal obstruction with struvite among the conformable than control catheters (1 (0·8%) versus 15 (11·5%); p<0·001).This new catheter for women is a substantial improvement over the Foley catheter and (except in urethral stricture) is suitable for all forms of drainage.  相似文献

To investigate which factors might protect against the development of retinopathy 40 insulin-dependent diabetics who had remained free from retinopathy despite diabetes of long duration (mean±1 SD 30±10 years) were compared with 40 patients who had background and 47 who had proliferative retinopathy (mean durations of disease 16±5 and 19±5 years respectively). The three groups had had similar mean ages at onset of diabetes. The mean of all postprandial blood glucose measurements at hospital clinics from diagnosis of diabetes to detection of retinopathy, or to the most recent negative eye examination, was 9·9±2·1 mmol/l (178±38 mg/100 ml) in the group with no retinopathy, 11·8±2·1 mmol/l (213±38 mg/100 ml) in those with background retinopathy, and 12·4±2·1 mmol/l (223±38 mg/100 ml) in those with proliferative retinopathy (p <0·0001). This difference was not reflected in present concentrations of haemoglobin A1C, probably because glycaemic control had been improved after the development of retinopathy. In the groups with background and proliferative retinopathy there were significant negative correlations between mean blood glucose concentrations and the number of years that had elapsed from diagnosis of diabetes to detection of retinopathy, suggesting that the development of both grades of retinopathy depends on the degree and duration of glycaemic exposure.The patients with no retinopathy had attended clinic more frequently (p <0·025), more of them had required emergency hospital treatment for hypoglycaemia (p <0·0025), and they tended to have had a lower prevalence of hyperglycaemic coma than the other groups. Although mean percentage ideal body weight and diastolic blood pressure were lower in the patients with no retinopathy at the time of study, mean body weight, blood pressure, and the prevalence of smoking in the years before the development of retinopathy had been similar in all groups, suggesting that these did not influence the development of retinopathy.  相似文献

A prospective study was made of 817 consecutive episodes of major gastrointestinal haemorrhage in patients admitted to hospital during 1967-8 from the defined population of North-East Scotland. The yearly admission rate was 116 per 100,000 population. Comparison of the data for city and country residents showed no appreciable differences. In the duodenal ulcer group there was an undue incidence of bleeding among foremen and skilled workers and among those who were unmarried or widowed.Both the clinical history and the results of any previous barium meal examinations were unreliable guides to the source of the current haemorrhage. Prognosis was worse for patients who did not have a dyspeptic history and was better for those who had bled on a previous occasion. The simultaneous ingestion of alcohol and aspirin had an adverse effect on the occurrence of bleeding. Forty-seven per cent. of the patients had another major coincidental disease.Mortality was 13·7% in the whole series and 8·6% in those with peptic ulcer (duodenal ulcer 7·1%, gastric ulcer 16·9%). In 28% of the patients further haemorrhage occurred after admission to hospital and caused a 28·8% mortality. Seventy-four patients were already in hospital when they first bled and 44% of them died.  相似文献

While the bone morphogenetic protein‐7 (BMP‐7) is a well‐known therapeutic growth factor reverting many fibrotic diseases, including peritoneal fibrosis by peritoneal dialysis (PD), soluble growth factors are largely limited in clinical applications owing to their short half‐life in clinical settings. Recently, we developed a novel drug delivery model using protein transduction domains (PTD) overcoming limitation of soluble recombinant proteins, including bone morphogenetic protein‐7 (BMP‐7). This study aims at evaluating the therapeutic effects of PTD‐BMP‐7 consisted of PTD and full‐length BMP‐7 on epithelial‐mesenchymal transition (EMT)‐related fibrosis. Human peritoneal mesothelial cells (HPMCs) were then treated with TGF‐β1 or TGF‐β1 + PTD‐BMP‐7. Peritoneal dialysis (PD) catheters were inserted into Sprague‐Dawley rats, and these rats were infused intra‐peritoneally with saline, peritoneal dialysis fluid (PDF) or PDF + PTD‐BMP‐7. In vitro, TGF‐β1 treatment significantly increased fibronectin, type I collagen, α‐SMA and Snail expression, while reducing E‐cadherin expression in HPMCs (P < .001). PTD‐BMP‐7 treatment ameliorated TGF‐β1‐induced fibronectin, type I collagen, α‐SMA and Snail expression, and restored E‐cadherin expression in HPMCs (P < .001). In vivo, the expressions of EMT‐related molecules and the thickness of the sub‐mesothelial layer were significantly increased in the peritoneum of rats treated with PDF, and these changes were significantly abrogated by the intra‐peritoneal administration of PTD‐BMP‐7. PTD‐BMP‐7 treatment significantly inhibited the progression of established PD fibrosis. These findings suggest that PTD‐BMP‐7, as a prodrug of BMP‐7, can be an effective therapeutic agent for peritoneal fibrosis in PD patients.  相似文献

The sand flea Tunga penetrans is one of the zoonotic agents of tungiasis, a parasitic skin disease of humans and animals. The dog is one of its main reservoirs. This negatively controlled, randomized, double-masked clinical trial evaluated the therapeutic and residual efficacy of fluralaner for treatment of dogs naturally infested with T. penetrans. Sixty-two dogs from an endemically affected community in Brazil were randomly assigned to either receive oral fluralaner (Bravecto chewable tablets) at a dose of 25 to 56 mg fluralaner/kg body weight, or no treatment (31 dogs per group). Dogs were clinically examined using a severity score for acute canine tungiasis (SCADT), parasitological examinations as defined by the Fortaleza classification, and pictures of lesions on days 0 (inclusion and treatment), 7 ± 2, 14 ± 2, 21 ± 2, 28 ± 2, 60 ± 7, 90 ± 7, 120 ± 7 and 150 ± 7. The percentage of parasite-free dogs after treatment was >90% between days 14 and 90 post-treatment with 100% efficacy on study days 21, 28 and 60. Sand flea counts on fluralaner treated dogs were significantly lower (p<0.025) than control dogs on all counts from day 7 to 120. The number of live sand fleas on treated dogs was reduced by > 90% on day 7, > 95% on days 14 and 90, and 100% from day 21 to 60, and with a significant difference between groups from day 7 to 120. From day 7 to day 120, mean SCADT scores were significantly reduced in treated dogs with a mean of 0.10 compared to 1.54 on day 120 in untreated dogs. Therefore, a single oral fluralaner administration is effective for treating and achieving long lasting (> 12 weeks) prevention for tungiasis in dogs.  相似文献

Background

The present study introduced a modified delta-shaped gastroduodenostomy (DSG) technique and assessed the safety, feasibility and clinical results of this procedure in patients undergoing totally laparoscopic distal gastrectomy (TLDG) for gastric cancer (GC).

Materials and Methods

A total of 102 patients with distal GC undergoing TLDG with modified DSG between January 2013 and December 2013 were enrolled. A retrospective study was performed using a prospectively maintained comprehensive database to evaluate the results of the procedure. Univariate and multivariate analyses were performed to estimate the predictive factors for postoperative morbidity.

Results

The mean operation time was 150.6±30.2 min, the mean anastomosis time was 12.2±4.2 min, the mean blood loss was 48.2±33.2 ml, and the mean times to first flatus, fluid diet, soft diet and postoperative hospital stay were 3.8±1.3 days, 5.0±1.0 days, 7.4±2.1 days and 12.0±6.5 days, respectively. Two patients with minor anastomotic leakage after surgery were managed conservatively; no patient experienced any complications around the anastomosis, such as anastomotic stricture or anastomotic hemorrhage. Univariate analysis showed that age, gastric cancer with hemorrhage and cardiovascular disease combined were significant factors that affected postoperative morbidity (P<0.05). Multivariate analysis found that gastric cancer with hemorrhage was the independent risk factor for the postoperative morbidity (P = 0.042). At a median follow-up of 7 months, no patients had died or experienced recurrent or metastatic disease.

Conclusions

The modified DSG was technically safe and feasible, with acceptable surgical outcomes, in patients undergoing TLDG for GC, and this procedure may be promising in these patients.  相似文献

A sequential Bayesian model has been developed for a computer and used to diagnose jaundiced patients admitted to hospital. Up to 102 items of information from the history, physical examination, and special investigations available within 48 hours of admission were collected on 309 patients. The results from these patients were used to calculate the probabilities of 11 possible diseases in 65 new patients and also to place patients into groups for medical or surgical treatment.The overall accuracy of the model in diagnosing patients as having one of 11 diseases was 69%, and where the final probability reached > 0·96, it was 89%. The overall accuracy in making a medical or surgical decision was 89%, and where the final probability reached > 0·96 it was 94%.Improvement in accuracy should result as the number of cases seen with rare conditions increases, and probably a similar model could be developed and used to make most use of those indicants with the highest cost-effectiveness.  相似文献

In February 1972 58% of patients euthyroid after iodine-131 therapy given for thyrotoxicosis between 1954 and 1966 had a high plasma TSH (>7·4 μU/ml) and 42% a normal plasma TSH level. A group of 69 of the euthyroid patients with high plasma TSH levels (25·0±2·0 μU/ml) in 1972 were re-examined 15 and 24 months later. The mean plasma TSH in the 66 patients remaining euthyroid at 15 months was 22·6±1·8 μU/ml, while three patients had become hypothyroid. At 24 months 64 of the patients were still available for study, of whom 61 remained euthyroid with a mean plasma TSH of 21·6±2·0 μU/ml, and a further three had become hypothyroid.All of a group of 61 of the euthyroid patients with normal plasma TSH levels (4·0±0·2 μU/ml) in 1972 remained euthyroid at 24 months with a mean plasma TSH of 4·1±0·3 μU/ml, though the plasma TSH level had become slightly raised in three.The mean serum T-4 level in the euthyroid patients with a high plasma TSH was significantly lower, though still in the normal range, than that in the euthyroid patients with a normal plasma TSH both in 1972 and in 1974.Since no patient with a normal plasma TSH level after iodine-131 treatment six to 18 years earlier for thyrotoxicosis developed hypothyroidism over a two-year period, the follow-up of such patients need not be so rigorous as that of similarly treated euthyroid patients with raised plasma TSH levels in whom hypothyroidism developed at the rate of 5% per year.  相似文献

BackgroundRecent circumstantial evidence suggests increasing number of Iranian patients with cutaneous leishmaniasis (CL) who are unresponsive to meglumine antimoniate (MA), the first line of treatment in Iran. Oral meltifosine was previously reported to be effective in visceral leishmaniasis as well CL. The current study is designed to determine efficacy and safety of oral miltefosine for the treatment of anthroponotic cutaneous leishmaniasis (ACL) cases who were refractory to MA in Iran.Methodology/Principal findingsMiltefosine was orally administered for 27 patients with MA resistant ACL with approved L.tropica infection, at a dosage of ∼2.5 mg/kg daily for 28 days. Patients were evaluated on day 14 and 28, as well as 3, 6 and 12 month post treatment follow up sessions. Laboratory data were performed and repeated at each visit. Data were analyzed using SPSS version 17. Twenty-seven patients including 16 men (59.25%) and 11 women (40.74%) with mean age of 28.56 ± 4.8 (range 3–54 years old) were enrolled. Total number of lesions were 42 (1–4 in each patient). Most of lesions were on face (76.19%). Mean lesions’ induration size was 2.38 ± 0.73 cm at the base-line which significantly decreased to1.31 ± 0.58 cm and 0.61 ±0.49 cm after 14 and 28 days of therapy, respectively (p value <0.05). At 12-months follow-up post treatment, 22 patients had definite/partial cure (81.48%) including 17 definitely cured patients, corresponding to a cure rate of 68% on per protocol analysis, and 62.96% according to intention to treat analysis. Recurrence of lesion was only occurred in one patient (3.70%). Nausea was the most subjective complication during the therapy (33.33%).ConclusionOral miltefosine could be an effective alternative for the treatment of MA-resistant ACL.  相似文献
