[Morbidity after cesarean section].

OBJECTIVE: To determine the frequency, spectrum of indications and complications and maternal morbidity rate connected with Caesarean sections as the most frequent mode of operative delivery. DESIGN: Retrospective, epidemiologic and comparative clinical study. SETTING: Department of Obstetrics and Gynecology, Jessenius Medical Faculty, Comenius University, Martin, Slovak Republic. METHODS: The authors retrospectively analyzed clinical data during a ten-years period. The number of deliveries, premature deliveries, frequency of Caesarean section, indications and maternal morbidity rate were determined. Further, a special attention was paid to premature deliveries and the related frequency of Caesarean sections and maternal morbidity rate in this group. In addition, the effectiveness of a complex pre-operative management was evaluated. RESULTS: The evidence shows that the natality rate is decreasing and the incidence of premature deliveries is increasing. The frequency of Caesarean sections is relatively stable with lower morbidity rate in the group of premature Caesarean deliveries. The positive effect of antibiotics, heparin and anti-aspiration medication within a complex pre-operative management was proved to decrease the frequency and severity of complications. CONCLUSIONS: The maternal morbidity rate following Caesarean delivery is relatively low, owing to the use of prophylaxis. However, it is vital to keep to the indications for Caesarean termination of the pregnancy, because there is still substantial mortality rate connected with it.

Effectiveness of vaginal douching on febrile and infectious morbidities after total abdominal hysterectomy: a multicenter randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of vaginal douching with 1 per cent povidone-iodine in reducing febrile and infectious morbidities after total abdominal hysterectomy (TAH). METHOD: The authors conducted a randomized controlled trial in 300 patients undergoing elective TAH in three hospitals in Northeast Thailand: a university, a regional and a general hospital. The patients were randomly allocated to the intervention or control groups. Patients in the intervention group received pre-operative vaginal douching with 1 per cent povidone-iodine while patients in the control group did not. External evaluators not apprised of the intervention assessed febrile and infectious morbidities. RESULTS: 300 patients were enrolled in the study. The incidences of febrile morbidity in patients with and without pre-operative vaginal douching were 25 and 35 per cent, respectively, though not statistically significant (risk difference -9.6%, 95% CI -19.9%, 0.8%, adjusted odds ratio 0.6, 95% CI 0.3%, 1.0%). A statistically significant difference in infectious morbidity was found between the groups (8 vs 19%, risk difference -10.0%, 95% CI -17.8%, -2.2%, adjusted odds ratio 0.4, 95% CI 0.2%, 0.9%). CONCLUSION: Pre-operative vaginal douching with 1 per cent povidone-iodine significantly reduces infectious morbidities after TAH.

Preoperative stratification of pancreas-related morbidity after the Whipple procedure.

Morbidity and mortality after pancreatoduodenectomy are greatly related to dehiscence of pancreatojejunostomy. We have analyzed risk factors of significance for and prediction of pancreas-related morbidity. We have retrospectively analyzed 122 patients. The relationship of fibrosis of pancreas, exocrine function, and diameter of pancreatic duct to pancreas-related morbidity was evaluated. Computer-aided morphometric analysis and the pancreatic elastase-1 stool test were used. Univariate analysis showed that the diameter of the main pancreatic duct and postoperative amylasemia were different in patients with and without pancreatic complications (P = 0.001 and P = 0.002, respectively). Pancreatic exocrine function was reduced and fibrosis was higher in patients without pancreatic complications (P = 0.003 and P = 0.026, respectively). Logistic regression analysis revealed exocrine pancreatic function as an independent risk factor. Pancreas-related morbidity is influenced by pancreatic fibrosis, diameter of pancreatic duct, and exocrine function. Preoperative evaluation of exocrine function allows detection of patients with minimal risk for pancreas-related morbidity.

[Risk factors of morbidity and mortality following surgical resection for hepatocellular carcinoma].

BACKGROUND/AIMS: Recently, mortality following surgical resection for hepatocellular carcinoma has been reduced significantly. Morbidity, however, is still significant. This study evaluated the risk factors leading to morbidity and mortality. METHODS: 510 patients who had a hepatic resection form Nov. 1994 to Dec. 2001 were included. The patient demographics showed a mean age of 51.6 years with a male to female ratio of 4:1. The HBsAg was positive in 76.0% and the anti-HCV was positive in 8.2%. The mean tumor size was 5.2 cm, 26.2% of patients had preoperative transcatheter arterial embolization (TAE), and 8.7% had preoperative percutaneous transhepatic portal embolization (PTPE). Limited resection was performed in 259 cases (50.7%), and major resection was conducted in 251 cases (49.1%). Risk factors included age, sex, laboratory findings (liver function test, prothrombin time, albumin, glucose, alpha-fetoprotein, ICG test), preoperative TAE, PTPE, operation type, operation time, intraoperative transfusion, tumor size, and cirrhosis. RESULTS: The morbidity was 10.5% (54 cases). Operative death occurred in 5 cases (1.0%). Hospital death, including operative death, occurred in 6 cases (1.2%). Five cases were associated with hepatic failure and 1 case was associated with aspiration pneumonia accompanying hepatic failure. Transfusion (P=0.002), glucose (P=0.002), and prothrombin time (P=0.038) were significantly related to morbidity. Age (P=0.028), glucose (P=0.011), and TAE (P=0.046) were significantly related to mortality. CONCLUSIONS: Intraoperative transfusion, which is mainly related to intraoperative bleeding, should be reduced if possible to decrease morbidity. Diabetes mellitus patients and the elderly need careful perioperative management.

Oesophageal atresia in premature infants: an analysis of morbidity and mortality over a period of 20 years.

AIM: To determine the morbidity and mortality of premature infants born with oesophageal atresia (OA) and to evaluate historical changes in morbidity and mortality over time. METHODS: Retrospective analysis of morbidity and mortality of all patients admitted for OA, with or without tracheo-oesophageal fistula, between 1982 and 2002. RESULTS: The study group consisted of 197 consecutive patients, of whom 55 (28%) were premature and 21 (11%) very premature. Type A atresia was found more often in very premature and premature infants than in those born at term (p = 0.02). Type E atresia was not found in the premature group (p = 0.004). At least one associated congenital anomaly was also present in 121 patients (61%). Postoperative complications developed more often in very premature and premature infants than in those born at term (p < 0.001). Gastro-oesophageal reflux was diagnosed in 32/76 premature infants and in 41/121 term infants (p = 0.001). Mortality among very premature and premature infants was higher than among those born at term (p = 0.003). Withdrawal of treatment was the most frequent cause of death. CONCLUSION: Premature infants with OA have a higher morbidity and mortality than term infants with OA. The complications of prematurity contribute significantly to morbidity and mortality in premature infants with OA. There is no reason to refrain from the standard treatment of OA in premature infants with no severe associated congenital anomalies.

[Medical and ecological assessment of climate effects on urolithiasis morbidity in population of Primorsky territory].

The article presents medicoecological estimation of quantitative relations between monsoon climate and urolithiasis primary morbidity in the Primorsky Territory. Quantitative estimation of the climate was performed by V. I. Rusanov (1973) who calculated daily meteorological data for 1 p.m. throughout 1991-1999. Primary urolithiasis morbidity for this period of time was provided by regional health department. The data were processed by methods of medical mapping and paired correlation analysis. In the Territory, mapping revealed the same location of the zones with high frequency of discomfortable weather of class V and VI causing chilblain in positive air temperatures and zones with elevated primary urolithiasis morbidity in children and adults. Correlation analysis confirmed mapping results and determined significant negative correlations between frequency of relatively comfortable moment weather classes II-IV and morbidity of children and adults, positive correlation between frequency of discomfortable class VI and adult morbidity. Thus, high frequency of days per year with discomfortable classes of moment weather in low positive air temperatures may be one of the factors of urolithiasis risk in population of the Primorsky Territory. Climatic factors should be taken into consideration in planning primary prophylaxis of this disease in the Primorsky Territory.

[Study of the prevalence of disturbance of activity and attention and co-morbid psychiatric disorders in the sample of Kaunas city primary school pupils].

Aim of the study was to evaluate the prevalence of disturbance of activity and attention and co-morbid psychiatric disorders among the primary school children in Kaunas city. Parents and teachers of all pupils of 12 randomly selected primary schools (N=2942) were asked to fill the scales on the presence of disturbance of activity and attention symptoms in their children. Disturbance of activity and attention was diagnosed if at least 6 symptoms of hyperactivity and/or 6 symptoms of inattention were present for at least 6 months according parents reports in DuPaul-IV scale and the result of teachers CAP scale exceeded the norms for age and gender. Both scales were obtained for 2298 pupils--1096 girls and 1202 boys 6-12 years of age. Disturbance of activity and attention was diagnosed for 5.2% of primary school pupils. It was 1.9 times more frequent among boys than among girls. Prevalence of co-morbid psychiatric disorders was estimated individually interviewing suspected children and their parents using M.I.N.I. Kid questionnaire. Out of all disturbance of activity and attention diagnosed children, 52.5% were also diagnosed co-morbid psychiatric disorders, most frequently oppositional defiant disorder (31.3%) and different types of anxiety disorders (18.0%). Prevalent type of disturbance of activity and attention and co-morbid disorders was related with the age of the pupils. Symptoms of hyperactivity and co-morbid psychiatric disorders had influenced motivation of parents to seek treatment for their children. Forty percent of the parents of children, who were diagnosed disturbance of activity and attention, have applied to the mental health care professionals; most of them evaluated the help they received as partly useful (57.9%) or not useful at all (26.3%).

[Predictive factors of morbidity and mortality after surgery in the elderly].

UNLABELLED: The aim of the study was to determine prognostic factors of post operative morbidity and mortality for patients aged 80 years and older. We compared two groups of patients aged 80 and over operated to determine predictive factors of morbidity and mortality: group of patients who presented post operative complication within 30 days after surgery and group of patients without any complication. Comparison of the two groups for global morbidity using univariate analysis showed only one prognostic factor: surgery of diabetic foot (p = 0.034). Predictive factors of mortality according to univariate analysis were: pre-operative shock (p = 0.001), abdominal wall pathology (p = 0.027), gastric or duodenal ulcer diseases (p = 0.011) and global morbidity (p = 0.006). After logistic regression, only pre-operative shock was an independent predictive factor of mortality (p = 0.0023). CONCLUSION: Risk for morbidity after surgery in the elderly 80 years and over is linked with type of surgery and not with soil. Likewise, risk for mortality is linked with advanced stage of disease that is presence of pre-operative shock and not with soil.

Stent-assisted angioplasty of intracranial vertebrobasilar atherosclerosis: midterm analysis of clinical and radiologic predictors of neurological morbidity and mortality.

BACKGROUND AND PURPOSE: Initial reports of stent-assisted angioplasty for intracranial vertebrobasilar atherosclerosis suggest this is a feasible treatment, but there have been little data regarding predictors of success or failure. We analyzed a series of patients for independent predictors of neurologic morbidity and mortality. METHODS: Patient charts and angiograms from 39 patients who underwent intracranial angioplasty and stent placement of vertebrobasilar stenoses were retrospectively reviewed to obtain clinical and detailed angiographic data on potential predictors of neurologic morbidity and mortality. Univariate analyses of these predictors were performed with either Fisher's exact test or simple logistic regression. Multivariate analysis was subsequently performed on the statistically significant predictors. RESULTS: Complete clinical data were obtained for 39 patients, and angiographic review was possible for 35 of them. Angiography revealed severe intracranial vertebral (n = 18), basilar (n = 15), or basilar and vertebral (n = 2) stenoses. Two patients (5.1%) died in the periprocedural period, nine patients (23.1%) had neurologic complications, and one patient (2.6%) had transient neurologic symptoms. Univariate analysis revealed female sex, diabetes, and failure of coumadin or heparin therapy were associated with neurologic morbidity, whereas female sex, Mori B lesion, and length-to-stenosis ratio were associated with mortality. The presence of diabetes was the only independent predictor of neurologic morbidity and mortality. CONCLUSION: Because of the limited number of patients available for analysis, the only independent predictor of neurologic morbidity and mortality was diabetes, but several other predictors showed trends that deserve further review in future series.

Differences in diabetic co-morbidity between Aboriginal and non-Aboriginal people living in Bella Coola, Canada.

INTRODUCTION OBJECTIVES: (1) To identify which medical disorders are significantly associated with being a diabetic in the setting of an isolated, rural community; and (2) to determine if there are differences between Aboriginal and non-Aboriginal diabetics. METHODS DESIGN: population based retrospective chart review. STUDY POPULATION: people living in the Bella Coola Valley, Canada, and having a chart at the Bella Coola Medical Clinic as at September 2001. MAIN OUTCOME MEASURES: known diabetes related co-morbidity (retinopathy, nephropathy, coronary artery disease, peripheral vascular disease, neuropathy). RESULTS: There were 126 adult (>18 years old) diabetics living in the Bella Coola Valley. Prevalence rates for history of alcohol issues, retinopathy, coronary artery disease, cerebrovascular disease, peripheral vascular disease, peripheral neuropathy, hypertension, hypercholesterolemia, and nephropathy were 44%, 14%, 19%, 8%, 7%, 10%, 54%, 47%, and 7% respectively. For the 1597 non-diabetics living in the Bella Coola Valley, respective prevalence rates for these same co-morbidities were 20%, 0.3%, 2%, 1.5%, 1%, 1%, 10%, 6%, and 0.6%. The study did not demonstrate that Aboriginal people living in the Bella Coola Valley have an increased prevalence of diabetes associated co-morbidities over and above that found in the non-Aboriginal diabetic population. This was despite the fact the smoking rate was higher in the Aboriginal population. CONCLUSIONS: The development of diabetes in both Aboriginal and non-Aboriginal people living in the Bella Coola Valley was clearly associated with the presence of multiple co-morbidities, including hypertension, hypercholesterolemia, coronary artery disease, cerebrovascular disease, and neuropathy. Rates of diabetes associated co-morbidities were similar for both Aboriginal and non-Aboriginal diabetic populations. The authors speculate that a diet rich in fish oils (omega-3 fatty acids) accounted for the lower than expected rates of cardiovascular disease among this Aboriginal population.

[Influence of labour conditions on the morbidity rate of workers of Georgian bread-making production].

The aim of the study was to evaluate influence of the working conditions on the morbidity of workers in Georgian bread-making production. The unfavourable labour conditions in Georgia with the dry subtropical climate, exerts influence on health status of workers of above mentioned production. By the data of the morbidity rate with temporal disability for the period 2000-2004 the average level of morbidity sick rate in the main group 5-7 times exceeds the analogous data of the control group. In the morbidity structure so called meteotropic diseases are leading, as well as diseases of cordial-vascular system are frequent (53,5% of all cases and 41,7% of all disability days). The morbidity structure in the study and the control groups was statistically different (X2=16,92/22,63). The conducted complex investigation has underlined elaboration of complex sanitary measurements.

Salient and co-morbid features in benign prostatic hyperplasia: a histopathological study of the prostate.

OBJECTIVES: To study the salient histological features of prostatic tissues in relation to age and to analyse the co-morbid histopathological changes in benign prostatic hyperplasia. (BPH). DESIGN: Prospective study. SETTING: Histopathology unit of a busy clinical pathological laboratory in Kathmandu Metropolitan City. SUBJECTS: 106 prostatic biopsy specimens from patients diagnosed as BPH received for histopathological examination during 2001-2. MAIN OUTCOME MEASURES: Prominent histological features observed in prostatic biopsy specimens obtained from patients of various age groups and frequency of co-morbid histopathological changes in benign prostatic hyperplasia. RESULTS: Prominent histological features. All (106) specimens included in the series had BPH showing glandulostromal proliferation of which 4 cases (3.77%) (all aged below 70 years) showed predominantly stromal pattern. Corpora amylacea present in 25% (in 5th decade) increased in frequency to 100% (8th decade onwards) in the later years. Cystically dilated glands also showed age correlated increase (through 5th to 8th decade) from 50% to 100%. Other prominent features observed with an overall decreasing frequency in all age groups (taken together) were glands showing papillary infoldings (44.33%), lymphocytic collection/infiltration (31.13%), proteinaceous material (7.54%), calcification (6.60%), homogenous eosinophilic material (2.83%), and glands showing necrotic cells (1.88%). Of all these, corpora amylacea, proteinaceous material, cystically dilated glands and glands showing papillary infoldings were present in all cases beyond 7th decade. Co-morbid histopathological changes of BPH. Twenty six specimens (24.52%) showed co-morbid features in association with BPH which included inflammatory (16.98%) and neoplastic (7.54%). Acute prostatitis was observed in 2 cases (1.88%), chronic prostatitis in 16 cases (15.09%) and none showed features of both. Neoplastic changes( 8 cases) ranged from intraepithelial neoplasm (PIN) (2 cases), atypical glands (2 cases, both in 7th decade) to adenocarcinomatous changes (2 cases, one each in 6th and 7th decade) were also observed co-existent with BPH. Both PIN cases (1.88%) were grade PIN-2 and occurred one each in the 6th and 7th decade. CONCLUSION: Histological profiles of prostatic biopsy specimens were observed to correlate well with the senile changes of advancing age. A predominantly stromal proliferation was found in a relatively lower age group, while corpora amylacea and cystically dilated glands along with glandular proliferation heralded changes of senescence. Co-morbid histopathological features were associated with BPH in a quarter (24.52%) of cases. Prostatitis was twice as common as neoplastic changes. Adenocarcinomatous changes were observed (2 cases) incidentally. PIN was recorded in 1.88% of specimens examined. Peak frequency of prostatitis was noted in the 6th decade while 7 of 8 neoplastic changes occurred in those of 60-80 years.

Preoperative vaginal preparations for abdominal hysterectomy for the prevention of febrile morbidity: savlon douching vs povidone-iodine painting.

OBJECTIVE: To compare the effectiveness between savlon solution was douching and povidone-iodine solution painting for reducing febrile morbidity after total abdominal hysterectomy. STUDY DESIGN: Clinical trial. MATERIAL AND METHOD: One hundred and fifty patients at Srinagarind Hospital were scheduled for total abdominal hysterectomy (TAH). All subjects were non-randomly allocated to receive either savlon (1:1000 solutions) douching or povidone-iodine (1% solution) painting as pre-operative vaginal preparations. They also received Cefazolin 1 gm. intravenously before the operation. The principal outcome of the study was febrile morbidity. RESULTS: The overall rate of febrile morbidity was 21 percent. The incidence of febrile morbidity in the savlon vs. povidone-iodine groups was 16 (12/75) and 25 (19/75) percent, respectively. No statistically significant difference was found between the two groups (p-value = 0.16). The odds ratio was 1.78 (95%CI 0.79 to 3.99) and adjusted odds ratio was 2.09(95%CI 0.86 to 5.10) CONCLUSION: The effectiveness between savlon solution douching and povidone-iodine solution painting in conjunction with a prophylactic antibiotic before TAH for reducing febrile morbidity was not significant different.

Audit of morbidity and mortality following neck of femur fracture using the POSSUM scoring system.

AIMS: The aims of this study were to compare the morbidity and mortality data for patients undergoing surgical fixation of a fractured neck of femur (during a 6-month period) to the predicted morbidity and mortality rates obtained from the POSSUM (Physiological and Operative Severity Score for the enUmeration of Morbidity and Mortality) scoring system, adapted for orthopaedic patients. The predictive accuracy of the orthopaedic POSSUM system is evaluated for this population. The 1-year mortality for the males and females of the study group (mean ages) is compared to the 1-year mortality of male and female New Zealanders of the same age. METHODS: Physiological and operative data was collected from patient notes; patient morbidity and mortality were obtained at 30 days and at 1 year postoperatively. The data were analysed with the orthopaedic POSSUM scoring system. RESULTS: 225 complete datasets were obtained. The mean age of the patients was 83 years; 75% were female. The observed 30-day morbidity and mortality rates were 58% and 12% respectively. The observed 1-year mortality was 38% for males (mean age 79 years) and 29% for females (mean age 84 years). New Zealand census data predicts 7% and 6.4% mortality respectively based on these mean ages. CONCLUSIONS: The POSSUM system allocates patients into groups of varying risk. The observed data shows higher numbers of complications, including death, in patients allocated into higher risk groups. The 1-year mortality is much higher than that predicted based on mean patient age from the New Zealand abridged life table.

Emergency gastric ulcer complications in elderly. Factors affecting the morbidity and mortality in relation to therapeutic approaches.

AIM: In elderly the incidence of the emergency gastric ulcer complications, perforation and bleeding are increasing, with a difficult management of these patients for their concomitant diseases. The aim of this work is to analyze the therapeutical approach of emergency gastric ulcer complications in elderly patients, in order to establish the factors affecting the morbidity and mortality. METHODS: Patients older than 70 years, presenting gastric ulcer, observed in a tertiary University Hospital from 1995 to 2003, have been considered for the present study. Two groups of diseases have been examined: ulcer perforation and bleeding ulcer. Age, sex, risk factors, comorbidity, methods of diagnosis, ulcer characteristics, treatment, morbidity, mortality, hospitalization time and follow-up have been considered in each group. RESULTS: Thirteen elderly patients with perforated gastric ulcer have been observed: 9 (69.2%) females and 4 (30.8%) males with a mean age of 80.5 years (range 70-90). Four patients were hospitalized in suburban hospital with an average time between the diagnosis and the surgery of 36 h, while the remnants were hospitalized directly in our Department with a medium waiting time of about 2 h. The surgical procedures were: simple closure with omentum patch in 11 cases (84.6%), and antrectomy in 2 cases (15.4%), in which the antrum was multiply perforated. Two patients presented an ulcer larger than 2 cm treated with simple suture and omental patch without morbidity and mortality. Three patients (23%) died postoperatively, due to septic shock, ventricular fibrillation and intraoperative massive haemorrhage, 2 of these patients came from other hospitals. Twenty-eight elderly patients with bleeding gastric ulcer have been observed during the same period: 13 (46.4%) females and 15 (53.6%) males with a mean age of 79.6 years (range 71-91). Except 2 patients submitted to endoscopic treatment both with adrenaline injection, all the remnant patients were managed with medical therapy (H2-receptor antagonist or proton pump inhibitors and in 7 patients [24.1%] antihaemorrhage drugs), and clinical observation, with a endoscopic control 3-4 days after from the first endoscopy. One of the 2 patients endoscopically treated developed a ulcer perforation after 11 days, and the other one rebled, without possibility of any kind of treatment due to his instable condition of health. Three patients (10.7%) died during their hospital stay not for causes strictly due to the gastric haemorrhage. CONCLUSIONS: Our results suggest that the early diagnoses and early treatment are 2 basic factor on the prognosis of elderly patients with perforated gastric ulcer. The choice between simple closure, with or without vagotomy, or gastrectomy depends from preoperative and operative health conditions of the patient. In patients with ulcer larger than 2 cm, Graham's technique can be performed safely if the preoperative and intraoperative conditions are favourable. Elderly patients with gastric ulcer bleeding show an high risk of morbidity and mortality, related to the risk factors like non steroid anti-inflammatory drugs (NSAIDs) intake or smoke. Repeated endoscopy and antiulcer drugs can manage the high stage patients of Forrest's classification with a low rate of morbidity and mortality. According to literature surgical treatment should be reserved after the second failure of endoscopic treatment.

[Colorectal cancer surgery. Analysis of risk factors in relation to incidence of morbidity and mortality].

The aim of the study was to investigate risk factors in relation to the incidence of morbidity and mortality in surgery for colorectal cancer. Between 1986-2005, 328 patients underwent colorectal cancer surgery, 308 of whom (93.9%) in elective and 20 (6.1%) in emergency surgery. Radical resection was performed in 276 (84.2%) and palliative surgery in 52 (15.8%) patients. Bivariate statistical analysis was used for morbidity and mortality factors and multivariate analysis was performed in order to find independent variables (age, gender, ASA grade, elective or emergency surgery, tumour excision, cancer stage according to Dukes) associated with dependent variable interactions. Differences were considered statistically significant for p values < 0.05. The incidences of mortality and morbidity were 0.91% and 20.1%, respectively. In our study we observed a leakage incidence of 2.74% (9/328). In emergency surgery we found morbidity and mortality rates of 20% and 10%, respectively. Age and advanced cancer stage influenced results but were not found to be statistically significant. 18.3% of patients (60/328) were ASA I, 32% (105/328) ASA II, 39.6% (130/328) ASA III and 10.1% (33/328) ASA IV. Among the independent variables observed in the multivariate analysis, ASA grade was found to be the only positive predictive factor correlated with morbidity. Logistic regression showed an exponential increase in operative risk: odds ratio (OR) 2.9 in ASA I vs ASA II, OR 4.2 in ASA I vs ASA Ill, OR 10.3 in ASA I vs ASA IV (95% confidence interval). As regards the mortality rate, none of the independent variables were found to be statistically significant risk factors (p < 0.05).

Predictors of in-hospital morbidity and mortality in patients with coronary artery disease treated with coronary artery bypass surgery.

AIM OF THE STUDY: The aim of our study was to identify markers that can predict early morbidity and mortality in patients with coronary artery disease who underwent coronary artery bypass surgery (CABG) for myocardial revascularization. MATERIAL AND METHODS: 749 patients (pts) were enrolled in the study at mean age 55 +/- 8 years, 639 male and 119 female. We analyzed pre-operative demographic, clinical, left ventricular morphologic and functional and angiographic variables, per-operative characteristics, and we registered occurrence of hospital complications including cardiac death during the first 30 days after the operation. RESULTS: Hospital complications were registered in 173 (23.1%) patients, including cardiac death registered in two (3%) patients during the first 30 days after the operation. The most common complications were: pericardial effusion (8.4%), supraventricular arrhythmias (6.3%) and pleural effusion (5.6%), followed by more serious complications like infections, acute renal failure and stroke. Advanced age (>or=65 years), coexisting morbidities and risk factors: cerebrovascular disease (CVD), peripheral vascular disease (PVD), chronic obstructive pulmonary disease (COPD), hypertension (HTA), previous myocardial infarction (MI), heart failure before the operation, extensive coronary artery disease (CAD) (angiographicly identified), low left ventricular ejection fraction (LVEF), and high WMSS index were identified as predictors of in-hospital morbidity. Advanced age, Mod Gensini score (as marker of angiographic severity of CAD) and WMSS index were found to be independent predictors of in-hospital morbidity, while advanced age, heart failure before CABG and in-hospital complications were found to be independent predictors of in-hospital mortality. CONCLUSION: In patients with coronary artery disease who underwent CABG surgery, preoperative variables and operative technique can predict occurrence of in-hospital morbidity, while early complications can strongly predict in-hospital mortality.

Morbidity patterns among employees at a petroleum refinery.

This study examined the morbidity experience of a prospective cohort of 2132 male employees who worked at a petroleum refinery from 1981 through 1988. The morbidity data included all illness-absence episodes in excess of 5 days during the study period. Standardized morbidity ratios (SMRs) of disease prevalence were calculated using data from all manufacturing employees of the Shell Oil Company as an internal comparison group. As such, there is no potential bias associated with the "healthy worker effect" in this type of study design. Morbidity for all causes combined was virtually the same as that for the comparison group with 2,311 observed and 2,318 expected disease prevalence events. However, there were statistically increased prevalence of musculoskeletal system disorders (SMR = 136) and injuries (SMR = 125) among staff employees and skin and subcutaneous tissue disorders (SMR = 138) among production employees. A review of the original morbidity reports for these skin conditions revealed that none were due to exposure to chemical products or solvents. The SMR for neoplasms of the lymphatic and hematopoietic tissue among production employees was slightly elevated but was based on only three cases (2.4 expected). Of the three cases, none was due to leukemia.
