Mortality differences between men and women following first myocardial infarction. RESCATE Investigators. Recursos Empleados en el Síndrome Coronario Agudo y Tiempo de Espera

CONTEXT: Mortality after acute myocardial infarction is worse in women than in men, even after adjustment for comorbidity and age dissimilarities between sexes. OBJECTIVE: To assess the influence of sex on survival after acute myocardial infarction. DESIGN: Inception cohort obtained in a prospective registry of patients with acute myocardial infarction from 1992 through 1994. SETTING: Four teaching hospitals in northeastern Spain. PATIENTS: All consecutive patients aged 80 years or younger with first acute myocardial infarction. A total of 331 women and 1129 men were included. MAIN OUTCOME MEASURE: Survival at 28 days and mortality or readmission at 6 months. RESULTS: Women were older (mean, 68.6 vs 60.1 years), presented more often with diabetes (52.9% vs 23.3%), hypertension (63.9% vs 42.3%), or previous angina (44.6% vs 37.4%), and developed more severe myocardial infarctions than men (acute pulmonary edema or cardiogenic shock occurred in 24.8% of women and 10.5% of men) (all P<.02). Men were more likely than women to receive thrombolytic therapy (41.3% vs 23.9%; P<.001), but rates of percutaneous transluminal angioplasty and coronary artery bypass graft surgery at 28 days were similar among men and women. The 28-day mortality rate was significantly higher among women (18.5% for women, 8.3% for men; P<.001). Revascularization procedures at 6 months were performed in a similar proportion of women and men. However, women had higher 6-month mortality rates (25.8% in women, 10.8% in men; P<.001) and readmission rates (23.3% for women, 12.2% for men; P<.001). After adjustment, women had greater risk of death than men at 28 days (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.12-2.65) and at 6 months (OR, 1.73; 95% CI, 1.18-2.52). CONCLUSIONS: In this study population, women experienced more lethal and severe first acute myocardial infarction than men, regardless of comorbidity, age, or previous angina.     

Hospital readmission after trauma: an analysis of outpatient complications

BACKGROUND: Outpatient complications leading to hospital readmission after hospitalization for trauma have not been examined. METHODS: A retrospective chart review of all trauma victims admitted to a Level 1 trauma center from January of 1990 to January of 1995 was performed to characterize patients who required readmission after hospitalization for trauma. Risk factors for readmission were determined by stepwise regression analysis. RESULTS: Of 15,463 trauma admissions, 209 patients (1.4%) required readmission, 84% within 30 days, 71% within 14 days. Reasons for readmission included wound (29%), abdominal (29%), pulmonary (18%), and thromboembolic (19%) complications. Fifty of the patients (24%) readmitted with a complication required an operation. Risk factors for readmission included: operation during first hospitalization (p < 0.0001), penetrating injury (p = 0.0001), and advanced age (p = 0.0001). Injury Severity Score, length of hospitalization, and gender were not independent predictors of readmission. CONCLUSIONS: Outpatient complications leading to readmission after hospitalization for trauma are not common; however, many are serious and require operative intervention. Because most complications were identified by the second week after discharge, outpatient follow-up visits should be scheduled within 7 to 14 days. Based on our findings, we recommend protocols be established to ensure follow-up for trauma patients, especially those who have had an operation, were victims of penetrating injury, or those > 65 years of age.     

Patients readmitted to the intensive care unit during the same hospitalization: clinical features and outcomes

OBJECTIVE: To determine the clinical features and outcomes of patients readmitted to the intensive care unit (ICU) during the same hospital stay and the causes for these readmissions. DESIGN: Multicenter, cohort study. SETTING: Three ICUs from two teaching hospitals and four ICUs from four community hospitals. PATIENTS: All ICU admissions were collected prospectively for a registry database in the seven ICUs. We retrospectively analyzed ICU admissions between January 1, 1995 and February 29, 1996. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the study period, 236 (4.6%) of the patients discharged alive from the ICU were readmitted to the unit. Patients with gastrointestinal (GI) and neurologic diagnoses had the highest readmission rate. Of the readmissions, 45% had recurrence of the initial disease, 39% experienced new complications, and 14% required further planned operation. Among patients readmitted for the same illness, cardiovascular and respiratory problems were the most frequent diagnoses. Of patients readmitted with a new diagnosis, 30% initially had GI diseases, while respiratory diseases accounted for 58% of the new complications. Readmissions within 24 hrs occurred in 27% of all readmissions. Patients requiring readmission had a higher hospital mortality rate (31.4%) compared with those not requiring readmission (4.3%, p < .001), even after adjustment for disease severity score (odds ratio = 5.93, p < .001). CONCLUSIONS: Patients with GI and neurologic diseases are at greatest risk of requiring ICU readmission. Respiratory diseases are the major reason for readmission due to new complications. Readmitted patients have a high risk of hospital death that may be underestimated by the usual physiologic indicators on either initial admission or readmission. Further studies are required to determine if patients at risk for readmission can be identified early to improve the outcome.     

Admission to hospitals with on-site cardiac catheterization facilities :impact on long-term costs and outcomes

BACKGROUND: Admission to a hospital with a capability for cardiac procedures is associated with a higher likelihood of referral for a cardiac procedure but not with a better short-term clinical outcome. Whether there are differences in long-term mortality and resource consumption is not clear. We sought to determine whether elderly Medicare patients with acute myocardial infarction admitted to hospitals with on-site cardiac catheterization facilities have lower long-term hospital costs and better outcomes than patients admitted to hospitals without such facilities. METHODS AND RESULTS: As part of the Cooperative Cardiovascular Project pilot in Connecticut, we conducted a retrospective cohort study using data from medical charts and administrative files. The study sample included 2521 patients with acute myocardial infarction covered by Medicare from 1992 to 1993. The cardiac catheterization rate was higher in the hospitals with facilities (38.6% versus 26.9%; P<0.001), but the revascularization rate was similar (20.5% versus 19.5%) during the initial episode of care and at 3 years (29.7% versus 29.7%). Mortality rates were similar for patients admitted to the 2 types of hospitals at 30 days (OR, 1.08; 95% CI, 0.83 to 1.42) and at 3 years (OR, 1.02; 95% CI, 0.83 to 1.26). The adjusted readmission rates were significantly lower among patients admitted to hospitals with cardiac catheterization facilities (OR, 0.76; 95% CI, 0.61 to 0.94). However, the overall mean days in the hospital for the 3 years after admission was 25.9 for patients admitted to hospitals with facilities and 24.6 for the other patients (P=0.234). Adjusting for baseline patient characteristics, there was no significant difference in the 3-year costs between patients admitted to the 2 types of hospitals. CONCLUSIONS: With higher rates of cardiac catheterization and lower readmission rates, patients admitted to hospitals with on-site cardiac catheterization facilities did not have significantly different hospital costs compared with patients admitted to hospitals without these facilities. There was also no significant difference in short- or long-term mortality rates.     

Radiotherapeutic management of cervical carcinoma that complicates pregnancy

BACKGROUND: Data regarding radiation therapy for pregnant patients with cervical carcinoma are limited. The goal of this study was to assess the effects of pregnancy on tumor control, survival, and morbidity associated with radiation therapy administered to pregnant patients. METHODS: The authors performed a retrospective case-control analysis of 26 women with cervical carcinoma who were diagnosed during pregnancy and treated primarily with radiation therapy. These cases were matched with 26 controls based on age, histology, stage, treatment, and year of treatment. RESULTS: Patients were treated with external beam radiation (mean dose, 46.7 gray [Gy]) and intracavitary radiation (mean dose, 56.5 Gy to Point A). Two patients with Stage IA2 squamous cell carcinoma treated in the third trimester had a planned delay in treatment of 3 weeks, and both infants had an uncomplicated neonatal course. Seven pregnant patients (2 Stage IB1, 5 Stage IB2) underwent radiation after radical hysterectomy was aborted due to positive regional lymph nodes. Three patients diagnosed during the first trimester were treated with radiation with the fetus in situ, and all had spontaneous abortions 20-24 days after the start of radiation (mean dose, 34 Gy). In all these cases, radiation was interrupted for only 3 days or less. There were no statistically significant differences in recurrence rates or survival between the pregnant group and the controls. Short term toxicity was comparable in pregnant and nonpregnant patients and easily controlled. Long term complications were more common in controls (12% in pregnant patients, 27% in controls), but this difference was not statistically significant. Most complications were likely related to radiation techniques (particularly the predominance of cobalt-60). CONCLUSIONS: Planned delay in treatment should be offered to pregnant patients with early stage squamous cell carcinoma in the late second and early third trimester. Patients diagnosed in the first or second trimester who are not good candidates for planned delay in treatment should be given radiation therapy immediately. It may be necessary to reconsider planned radical hysterectomy for pregnant women with Stage IB2 disease due to the high rate of lymph node positivity found on exploration. For patients with advanced disease, radiation therapy appears to be a safe and effective modality.     

Outpatient hysterectomy: determinants of discharge and rehospitalization in 133 patients

OBJECTIVE: This study examines our continuing experience in performing vaginal hysterectomies and laparoscopy-assisted vaginal hysterectomies with an outpatient protocol. The purpose was to review factors associated with discharge and hospitalization. STUDY DESIGN: Surgical records from all women entering our previously reported outpatient hysterectomy protocol were reviewed. Demographics, surgical indications, intraoperative data, and postoperative data were studied, and their associations with patient discharge and hospitalization were determined. Specific attention was directed to complications. RESULTS: The study group consisted of 133 women. Twelve women (9.0%) were not discharged from the hospital and 5 (3.8%) required readmission. Surgical indications, the type of hysterectomy, and the requirement for pain medication revealed no association with hospitalization. The occurrence of an intraoperative complication (p < 0.000), the need for transfusion (p = 0.043), and postoperative antiemetics (p = 0.013) were statistically associated with hospitalization. In addition, low hematocrit values and elevated temperatures on the first and second postoperative days were associated with hospitalization. CONCLUSION: Long-term experience with outpatient hysterectomy reveals a hospitalization rate of 12.8%. Complications, blood loss, elevated temperatures, and postoperative nausea are the major determinants of patient discharge and hospitalization. Readmission rates continue to remain low.     

Hysteroscopic endometrium ablation to avoid hysterectomy in "high risk" patients

Hysteroscopic endometrial ablation under maximal anaesthesiological surveillance was performed in 34 high-risk patients to avoid hysterectomy. It was a collective of patients with heavy thrombo-embolic or thrombotic disease, either under permanent anticoagulation due to residual disease or multiple endoprosthetic treatment, or with endogenous coagulopathy. In all these women, hysterectomy was either a relative or an absolute contraindication. In 22 patients, treatment resulted in complete amenorrhoea or at least hypomenorrhoea (without menometrorrhagia) respectively cyclic spotting. In 6 further patients, amenorrhoea was achieved after a repeat procedure. Endometrial ablation was thus successful in 28 of 34 cases. In these patients, hysterectomy with the risk of major or even lethal complications, could thus be avoided. Hysterectomy, however, had to be performed in 2 women with extensive adenomyosis uteri interna. Within two respectively three years after endometrial ablation, two other patients died from causes unrelated to the surgical intervention (cardiac infarction, cerebral haemorrhage). Follow-up ranged from 1 to 5 years. Hysteroscopic endometrial ablation proved an effective therapeutic option in this selected group of patients. Other indications require further study.     

Elective cervical discectomy in California: postoperative in-hospital complications and their risk factors

STUDY DESIGN: A retrospective cohort study of short-term outcomes after elective cervical discectomy in California hospitals. OBJECTIVES: To compare the frequency of elective cervical discectomy across population strata, to determine the frequency of adverse outcomes in the early postoperative period, and to identify risk factors for such outcomes. SUMMARY OF BACKGROUND DATA: Previous cervical discectomy series have been too small to analyze risk factors for early complications, and have originated from centers that may not adequately represent the population. METHODS: Computerized hospital discharge abstracts were obtained from the California Office of Statewide Health Planning and Development. Inclusion and exclusion criteria were applied to identify 10,416 routine discectomies at 257 hospitals in 1990-1991. Several categories of postoperative complications were identified, along with inpatient deaths, early reoperations, and nursing home transfers. Logistic regression was used to estimate the independent effects of patient characteristics on short-term outcomes. RESULTS: After adjustment for age and gender, blacks were 51% and Hispanics were 24% as likely as whites to undergo elective cervical discectomy. Overall, 6.7% of patients had one or more reported postoperative complications: 1.8% had noninfectious surgical complications, 1.8% had infectious complications, 4.0% had other medical complications, and 0.35% had unplanned reoperations before discharge. Fourteen inpatient deaths were reported (0.13%). Congestive heart failure, alcohol/drug abuse, chronic lung disease, previous spine surgery, psychological disorders, and chronic musculoskeletal disorders were independently associated with postoperative complications. Even after adjustment, risk was higher with advancing age, higher among women than among men, and higher after posterior fusion than after discectomy without fusion. CONCLUSIONS: The ethnic disparity in cervical discectomy rates suggests overuse among whites or underuse among minority populations. The complication rates reported here are similar to those synthesized from previous literature, except that the lower incidence of neurologic complications reflects our inability to distinguish preoperative from postoperative deficits. Important comorbidities should be identified and treated, if appropriate, before cervical spine surgery.     

Chlorhexidine as a root canal medicament for treating inflammatory lesions in the periodontal space

OBJECTIVE: Abnormal uterine bleeding is a common and troublesome problem in human immunodeficiency virus (HIV)-infected women. We sought to evaluate endometrial pathology among HIV-infected women requiring hysterectomy to explore if endometritis may be common among these patients. METHODS: We performed a retrospective analysis of uterine pathology specimens obtained from HIV-infected and control patients requiring hysterectomy in two urban hospitals between 1988 and 1997 matched for age, surgical indication, and history of gonadotropin-releasing hormone (GnRH) use. Cases were evaluated for the presence of plasma cells and assigned a grade between 0 and 3. RESULTS: Indications included cervical dysplasia (4), carcinoma in situ (2), abnormal uterine bleeding (3), and adnexal mass (3). Some degree of abnormal uterine bleeding occurred in all cases. Plasma cell endometritis was twice as common in HIV-infected women compared to HIV-negative specimens (11/11 versus 11/22) (P < 0.05). Plasma cell endometritis was also of a higher grade in specimens from HIV-infected women than in controls (P = 0.001). CONCLUSION: Chronic endometritis was common and of a higher grade among HIV-infected women requiring hysterectomy in our series. Diagnosis and treatment of endometritis should be considered in HIV-infected women with uterine bleeding and/or tenderness. We speculate that antiretroviral and/or antimicrobial treatment for endometritis may effectively treat endometritis and eliminate the need for surgery in some HIV-infected women. We suggest that consideration and treatment of endometritis in HIV-1 infected women being evaluated for possible hysterectomy has the potential to reduce costs and morbidity for patients and providers who may be exposed during surgical procedures.     

Implantable venous access devices in children with hemophilia: a report of low infection rates

OBJECTIVE: The objective of this study was to define the efficacy and complications of implantable venous access devices (IVADs) in children with hemophilia. STUDY DESIGN: Records were reviewed on all patients with congenital blood coagulation disorders monitored at two children's hospitals in whom one or more central venous catheters had been placed. RESULTS: Since 1989 external and implantable central venous catheters have been inserted to enhance venous access for regular factor concentrate infusion in 45 patients with hemophilia ranging in age from 8 months to 19.5 years (median 7.4 years); 37 patients had factor VIII deficiency and 8 factor IX deficiency. Hemorrhagic complications of catheter placement were infrequent and minor. In the 41 patients having one or more IVADs in place for a median of 31 months, only six episodes of bacteremia occurred in 5 patients during 44,070 days of follow-up. The overall rate of bacteremia complicating IVADs in these patients was 0.14 episodes per 1000 catheter days. Other catheter-related complications were uncommon. Catheters are still in place in 33 patients for a median of 32 months. CONCLUSION: The low risk of infection and other complications associated with the use of IVADs makes the use of these devices attractive in the treatment of patients with hemophilia who require frequent venous access for factor concentrate infusions.     

Quality assurance in roentgen diagnosis. Comparison of constancy test methods according to DIN and IEC and practical consequences in Germany

A total of 437 patients who had undergone hysterectomy in the department of Obstetrics and Gynaecology, Heinrich Braun Clinic, Zwickau, between 1982 and 1992 were asked about vegetative and psychological problems after the operation. All were under 42 years old and had at least one ovary left intact. In all, 245 women returned the questionnaires. After hysterectomy 26.1% reported ovarian failure and 36.7% did not observe typical menopausal symptoms. Symptoms were significantly more frequent in patients where ovary had been removed. It made no difference whether a vaginal or an abdominal incision had been made. Psychic problems were reported by 17.6% of the patients. Patients with ovarian failure had more negative symptoms. Postoperatively, 34 women received hormonal therapy, and 10 of them finished the therapy successfully. The rate of ovarian failure and psychic symptoms can be reduced by adequate information before and after hysterectomy. A decision to perform a hysterectomy should be made only if the operations is strictly indicated. Prophylactic oophorectomy should not be performed in patients under 50 years. Effective hormonal substitution is recommended for patients with menopausal symptoms.     

Influence of age and hospital volume on the results of carotid endarterectomy: a statewide analysis of 9918 cases

PURPOSE: This study evaluated the impact of patient age and hospital volume on the results of carotid endarterectomy (CEA) in contemporary practice. METHODS: The Maryland Health Services Cost Review Commission (MHSCRC) database was reviewed to identify all patients who underwent elective CEA as the primary procedure in all acute care hospitals in the state over the past 6 years. RESULTS: From January 1990 through December 1995, 9918 elective CEAs were performed in 48 hospitals at a total charge of $68.9 million. Postoperative death and neurologic complications occurred in 90 (0.9%) and 166 (1.7%) cases, including 0.8% and 1.7%, 0.9% and 1.6%, 0.9% and 1.8%, and 1.4% and 1.3% of patients < 65 years, 65 to 69 years, 70 to 79 years, and > or = 80 years old, respectively. The mean length of stay and hospital charges increased linearly with increasing age: 4.2 days/$6550, 4.4 days/$6834, 4.8 days/$7059, and 5.6 days (p < 0.0001 vs others)/$7756 (p < 0.005 vs 70 to 79 years and p < 0.0003 vs < 70 years old), respectively, for patients < 65, 65 to 69, 70 to 79, and > or = 80 years old. The mortality rate was 1.9% in low-volume hospitals, 1.1% in moderate-volume hospitals, and 0.8% in high-volume hospitals. The neurologic complication rate was significantly higher (6.1%; p < 0.0001) in low-volume when compared with moderate-volume (1.3%) and high-volume (1.8%) hospitals. CONCLUSIONS: CEA is a safe procedure in the majority of hospitals in contemporary practice, even among the very elderly, who may experience a longer length of stay and higher charges correlating with their documented greater medical complexity.     

Antibiotic prophylaxis of infectious complications in gynecologic surgery]

Infections are still the most frequent postoperative complications and one of the limiting factors of successful gynaecological surgery. In recent years information on successful anti-microbial chemoprophylaxis is increasing and is associated with reduced postoperative inflammations, febrile morbidity and early complications. Views differ above all as regards indications for the use of antibiotic prophylaxis and the selection of a suitable antibiotic. Data in the literature differ also as regards achieved results. The submitted work had the objective to test on a representative group the success and rationality of medicamentous prophylaxis in gynaecological surgery and to contribute to a clearer view on controversial points. 203 women admitted to the Second Gynaecological and Obstetric Department of the First Medical Faculty Charles University and General Faculty Hospital Prague for elective abdominal or vaginal hysterectomy on account of a benign indication were divided into three groups which did not differ from the demographic or medical aspect. In group A (53 women) for prophylaxis two doses of Augmentin were used (combination of amoxycillin with clavulanic acid) i.v., patients in group M (50 women) had three doses of Mandol (Cefamandol) i.m., and in control group K (100 patients) no antibiotics were administered prophylactically. The authors investigated the postoperative course and evaluated some parameters in relation to possible postoperative infectious complications. The results proved unequivocally that prophylaxis with Augmentin reduces significantly the postoperative infectious morbidity (11.5%), febrile morbidity (5.6%) and the incidence of early infectious complications (3.8%) after abdominal or vaginal hysterectomy, as compared with the control group (35%, 31% and 11% resp.). Prophylaxis with Cefamandol reduced only in few parameters postoperative complications, but in general did not lead to a significant improvement of the postoperative course nor to a reduction of postoperative inflammatory complications. Similar results were obtained when only complications after abdominal hysterectomy were evaluated. The results of bacteriological examination confirmed the expected differences in the spectrum of efficacy of the two antibiotics on the most common microbial flora in the given area, i.e. a high sensitivity of Augmention to enterococci and bacterioids and resistance of these bacteria to Mandol. These results can be considered one of the reasons of different results of the two antibiotics. Prophylaxis with amoxycillin/clavulanic acid was found to be safe, very effective and financially feasible prevention of postoperative infectious complications after abdominal and vaginal hysterectomy. It led to a significant increase in the number of cases without any complications, when compared with the control group.     

The perioperative morbidity of scheduled cesarean hysterectomy

OBJECTIVE: To compare the outcomes of patients undergoing scheduled cesarean hysterectomy with those of women treated with cesarean delivery and subsequent hysterectomy. METHODS: Through a retrospective review of 43 patients, we investigated the morbidity associated with scheduled cesarean hysterectomy and compared these findings with the combined morbidity of scheduled cesarean delivery and subsequent abdominal hysterectomy in a control population. Controls were included only if the subsequent hysterectomy was performed within 3 years of the index cesarean delivery. Each study subject was assigned two controls matched for age, parity, number of previous cesarean deliveries, and indications for procedures. The incidence of the following major morbidity events was compared between the groups: transfusion, urinary tract injury, fistula formation, cellulitis or endometritis, postoperative abscess or hematoma formation, ileus, pneumonia, and wound complications requiring prolonged therapy (seroma, hematoma, infection). RESULTS: The number of women receiving transfusions after scheduled cesarean hysterectomy was greater than among controls (39.5 versus 15.1%; P < .05). The proportion of patients with major morbidity, exclusive of transfusion, was significantly greater in the control population (44%) than in women with scheduled cesarean hysterectomy (16%) (P < .05). The cumulative number of women with a major complication, such as transfusion or a morbid event, was 22 of 43 in the study group versus 44 of 86 in the control population, a nonsignificant difference. CONCLUSION: We found no significant difference in the cumulative perioperative complication rates in women undergoing scheduled cesarean hysterectomy compared with a population of similar patients treated with cesarean delivery and subsequent abdominal hysterectomy.     

Unrelated donor bone marrow transplantation without T cell depletion using a chemotherapy only condition regimen. Low incidence of failed engraftment and severe acute GVHD

STUDY OBJECTIVE: To assess the efficacy and safety of operative resectoscopy, partial endomyometrial resection, and endometrial ablation in the evaluation and treatment of abnormal uterine bleeding. DESIGN: Retrospective analysis of 305 consecutive cases of endometrial ablation and partial endomyometrial resection. SETTING: Midwestern urban obstetric and gynecology group practice and teaching hospitals. PATIENTS: Three hundred five women (age 30-72 yrs) with abnormal uterine bleeding. Interventions. Partial endomyometrial resection and endometrial ablation. MEASUREMENTS AND MAIN RESULTS: Of the 301 patients who completed surgery and follow-up, 283 (97%) reported improvements in amenorrhea (55%), hypomenorrhea (41%), and eumenorrhea (1%). Ten (3%) failed to report improvement. In 24 (7.9%) women, hysterectomy was performed for various reasons after endometrial ablation, including recurrent bleeding in 4. Four uterine perforations occurred, infection was suspected in one patient, and loss of Laminaria occurred in another; all patients, however, were observed appropriately and discharged the same day of surgery. CONCLUSIONS: Partial endomyometrial resection and endometrial ablation is a safe and effective treatment of abnormal uterine bleeding, and may be an alternative to hysterectomy in selected patients.     

Percutaneous intentional extraluminal (subintimal) recanalization: how to do it yourself

INTRODUCTION AND OBJECTIVES: The high demand for health care has obliged Coronary Units to hasten the discharge of patients in less serious condition and this might be an influence on their prognosis. Our objective have been: a) to analyse the characteristics and the evolution (death or readmission) during the first month of patients with myocardial infarction and very early discharge from the Coronary Unit (stay of 2 days or less), and b) to assess the profile of very low risk group patients for complications who could be discharged early from the Coronary Unit. PATIENTS AND METHODS: A study of 978 consecutive patients who had been admitted for acute myocardial, in faration were divided into two groups according to their length of stay in the Coronary Unit (A < or = 2 and B > 2 days). Their baseline characteristics, course of stay and vital status at month, were compared. A subgroup of patients at low risk was studied and complications that might have arisen from their early discharge from the Coronary Unit were assessed. RESULTS: Seventy-three patients (7.5%) died within the first two days. Of the remaining 905, the stay was 2 days or less for 336 patients (group A); and longer than 2 days for 569 (group B). Group A had a higher frequency of dyslipemia, Killip class I on admission, uncomplicated myocardial infarction in the Coronary Unit and the use of beta-blockers and had less frequency of diabetes, Q wave myocardial infarction, anterior infarction or the use of fibrinolytics. In the first month after discharge from the Coronary Unit, 10 patients from group A and 18 patients from group B died, the rate of death or readmission into the Coronary Unit within 30 days was similar between both groups (group A = 13% and group B = 13%). A multiple regression showed that Killip class on admission (p < 0.001) and an uncomplicated course (p < 0.001) were independently related with the length of stay in the coronary unit. A subset of 378 low risk patients (Killip I on admission, uncomplicated course in the ICU and age < 71 years) had no mortality at 30 days and their readmission rate in the first month was 4%. In this subgroup, those patients whose stay was equal to or less than two days were more frequently readmitted in the first week. (group A = 9/197 [5%] and group B = 1/181 ([0.5%]; p = 0.034). CONCLUSION: Selected patients with myocardial infarction can be discharged very early from the Coronary Unit with a low risk of death. A readmission rate following discharge of some 5% must be allowed for these patients.     

Long-term prognosis of reactive salmonella arthritis

OBJECTIVES: Reactive joint complications triggered by salmonella gastroenteritis are increasingly reported, but the outcome and long term prognosis of the patients is incompletely known. This study looked at the prognosis of salmonella arthritis in patients hospitalised in 1970-1986. METHODS: Hospital records from two hospitals in southern Finland were screened for patients with the discharge diagnosis of salmonellosis or reactive, postinfectious arthritis or Reiter's disease. For the patients with confirmed diagnosis of reactive salmonella arthritis, data about the acute disease were collected from the hospital records. A follow up study was performed. RESULTS: There were 63 patients (28 women, 35 men, mean age 36.5 years) with salmonella arthritis. Urethritis occurred in 27%, eye inflammation in 13%, and low back pain in 44% of the patients. HLA-B27 was present in 88%. More men than women were HLA-B27 positive. HLA-B27 positive patients had higher erythrocyte sedimentation rate (mean 80.9 v 46.5 mm 1st h, p = 0.0180). Also, extra-articular features and radiological sacroiliitis were seen only in HLA-B27 positive patients. A follow up study was performed on 50 patients mean 11.0 (range 5-22 years) later. Twenty patients had recovered completely. Ten patients had mild joint symptoms, 11 patients had had a new acute transient arthritis, and five acute iritis. Eight patients had developed chronic spondyloarthropathy. Radiological sacroiliitis was seen in six of 44 patients, more frequently in male than in female patients (32% v 0%; p = 0.0289). Recurrent or chronic arthritis, iritis or radiological sacroiliitis developed only in HLA-B27 positive patients. CONCLUSION: Joint symptoms are common after reactive salmonella arthritis. HLA-B27 contributes to the severity of acute disease and to the late prognosis.     

Pregnancy in patients with pulmonary autograft valve replacement

AIM: The purpose of this study is to determine the outcome and complications of pregnancy in women with pulmonary autograft valve replacement for aortic valve disease. METHODS AND RESULTS: The records of all women who had undergone pulmonary autograft valve replacement at the National Heart Hospital (now Royal Brompton Hospital) since 1968 were reviewed. From 1968 to 1993, 27 hospital survivors were female and among eight of them there were 14 pregnancies. All women were in Ability Index 1 at time of pregnancy with normal ventricular function, mild aortic regurgitation (six), mild pulmonary regurgitation (three) and mild pulmonary stenosis (two). None took anticoagulants. There was no maternal death, thromboembolic or haemorrhagic event or evidence of deterioration in valve function during pregnancy. Except for one woman (Ability Index 3) who developed dilated cardiomyopathy without aortic or pulmonary valve disease 6 months after delivery, the women remained in Ability Index 1 after pregnancy. There was no significant progression of aortic regurgitation (mild after seven pregnancies), pulmonary regurgitation (mild after six) or right-sided obstruction (mild after four). Reoperation for right-sided obstruction was carried out in two patients 4 and 7 years after a second pregnancy (9 and 15 years after the pulmonary autograft). CONCLUSION: No valve-related complications occurred during pregnancy and pregnancy appeared to have no effect on the function of the pulmonary valve autograft or the right-sided homograft. The pulmonary autograft is thus an ideal procedure for a young female needing aortic valve replacement.     

Survival in disseminated sclerosis in Denmark. A nation-wide study of the period 1948-1986

We estimated survival probability and excess death rates for patients with multiple sclerosis (MS) on the basis of data from the Danish Multiple Sclerosis Registry, which includes virtually all patients diagnosed with MS in Denmark since 1948. We reviewed and reclassified all case records according to standardized diagnostic criteria. By linkage to the Danish Central Population Registry and the National Registry of Causes of Death complete follow-up of all MS patients was achieved, with the exception of 25 patients who had emigrated. A total of 2300 of the 6727 MS patients included in the study had died before the onset of the disease was 28 years in men (compared with 40 years in the matched general male population) and 33 years in women (versus 46 years). The excess death rate between onset and follow-up (observed deaths per 1000 person-year minus the expected number of deaths in a matched general population) was 14.3 in men, which was significantly higher than in women (12.0). Excess mortality increased with age at onset of MS in people of each sex. The 10-year excess death rate has decreased significantly in recent decades. Excess mortality was highest in cases with cerebellar symptoms at onset.     

Uterine leiomyomata--a feature of acromegaly

In order to assess the prevalence of leiomyomata in patients diagnosed with acromegaly, files of all women so diagnosed were obtained (n = 25). Eight of these patients had undergone hysterectomy. In eight of the remaining patients, assessment of the uterus was performed by gynaecological examination and transvaginal ultrasound. The prevalence of leiomyomata was 81% (13/16) in patients who had undergone hysterectomy (8/8) or who underwent gynaecological examination (5/8). In conclusion, the very high prevalence of leiomyomata in patients diagnosed with acromegaly warrants the inclusion of growth hormone excess as a cause of leiomyomata. Leiomyomata are a feature of the organomegalic syndrome associated with acromegaly.
