The prevalence of gallstone disease (cholelithiasis and previous cholecystectomy for gallstones) in the population of the town of Sirmione, Italy, examined by ultrasonography, was 6.7% in men and 14.6% in women, ranging from 18 to 65 yr of age (overall prevalence = 11%). The prevalence of cholelithiasis in the same age span was 6.9% (4.5% in men and 8.9% in women). Prevalence of cholelithiasis increased with age in both sexes. Twenty-two percent of gallstone subjects suffered from biliary pain vs. 2% of subjects without gallstones. No difference was observed in the frequency of nonspecific symptoms between subjects with and without gallstones. Of the 132 gallstone subjects, 108 (82%) were not aware of having gallstones prior to the study. Prevalence of gallstone disease was found to be higher in obese and hypertriglyceridemic subjects and to increase with the number of pregnancies.
This study was designed to obtain a general overview of gallstone disease in Italy. A total of 18 cohorts in 10 Italian regions were enrolled in this survey. Four cohorts were excluded from analysis because of a participation rate of less than 50 percent. Field activities started in December 1984 and terminated in April 1987. A precoded questionnaire was administered to each subject by a trained member of the medical staff. Participants underwent an ultrasonographic examination of the upper abdomen and blood sampling. Each research group was provided with an identical ultrasonographic machine. Standardized criteria were established for both the examination and diagnosis. The inter- and intraobserver variation in the ultrasonographic procedure was assessed using a reliability study. The overall kappa score for interobserver agreement was good (0.649), while intraobserver agreement was good or excellent (kappa scores > 0.60) in 75 percent of the observers. A total of 29,739 of the 46,139 (64.4 percent) enrolled subjects were examined. Among those with a clear-cut definition of the gallbladder status, 6.5 percent of the males and 10.5 percent of the females had gallstones. Additional 3.0 and 8.4 percents, respectively, had already undergone cholecystectomy. Prevalence of gallstone disease (gallstones plus cholecystectomy) increased linearly with age in both sexes. Among subjects with gallstones, 76.7 percent of men and 72 percent of women were not aware of having gallstones; 87.0 percent of men and 84.9 percent of women were asymptomatic. This study confirms that gallstone disease is a highly prevalent condition. Gallstones rarely cause symptoms, and subjects are mostly unaware of their presence.
The aim of this study was to evaluate the incidence, radiographic appearance, time of onset, outcome and risk factors of non-infectious and infectious pulmonary complications following liver transplantation. Chest X-ray features of 300 consecutive patients who had undergone 333 liver transplants over an 11-year period were analysed: the type of pulmonary complication, the infecting pathogens and the mean time of their occurrence are described. The main risk factors for lung infections were quantified through univariate and multivariate statistical analysis. Non-infectious pulmonary abnormalities (atelectasis and/or pleural effusion: 86.7%) and pulmonary oedema (44.7%) appeared during the first postoperative week. Infectious pneumonia was observed in 13.7%, with a mortality of 36.6%. Bacterial and viral pneumonia made up the bulk of infections (63.4 and 29.3%, respectively) followed by fungal infiltrates (24.4 %). A fairly good correlation between radiological chest X-ray pattern, time of onset and the cultured microorganisms has been observed in all cases. In multivariate analysis, persistent non-infectious abnormalities and pulmonary oedema were identified as the major independent predictors of posttransplant pneumonia, followed by prolonged assisted mechanical ventilation and traditional caval anastomosis. A "pneumonia-risk score" was calculated: low-risk score ( < 2.25) predicts 2.7% of probability of the onset of infections compared with 28.7% of high-risk (> 3.30) population. The "pneumonia-risk score" identifies a specific group of patients in whom closer radiographic monitoring is recommended. In addition, a highly significant correlation (p < 0.001) was observed between pneumonia-risk score and the expected survival, thus confirming pulmonary infections as a major cause of death in OLT recipients.
Increasing age and BMI represent true risk factors for gallstone disease (GD); pain in the right hypocondrium and/or epigastrium is confirmed as the only symptom related to gallstones.
In this study, the striking decrease in the level of serum LDL cholesterol in patients with liver disease was related to the increasing severity of the disease. Accordingly, the assessment of the serum LDL cholesterol level is important for an effective treatment and prognostic evaluation of patients with chronic liver disease.
Abstract:Objective: Sleep disturbance and excessive daytime sleepiness have been reported in patients with hepatic cirrhosis. The objective of this study was to evaluate daytime somnolence and sleep complaints in a group of 178 patients with cirrhosis compared to a control group.Method: Sleep features and excessive daytime sleepiness were evaluated by the Basic Nordic Sleep Questionnaire (BNSQ) and the Epworth Sleepiness Scale (ESS). We collected clinical and laboratory data, neurological assessment and EEG recording in cirrhotic patients.
Results:Patients with cirrhosis complained of more daytime sleepiness (p<0.005), sleeping badly at least three times a week (p<0.005), difficulties falling asleep (p<0.01) and frequent nocturnal awakening (p<0.005) than controls. We found a poor correlation between sleep disorders and clinical or laboratory parameters. Conclusion: Our results confirm previous literature reports suggesting a high prevalence of sleep disturbance in patients with cirrhosis.Insomnia and daytime sleepiness are the main complaints. Sleep disorders are probably a multifactorial phenomenon.
SUMMARY
BackgroundMany investigators have proposed an association between gastro-oesophageal reflux disease and laryngo-pharyngeal symptoms, suggesting that medical or surgical therapy for reflux may be useful.
