RESUMO
BACKGROUND: Liquorice consumption can cause pseudohyperaldosteronism and potentially lead to life-threatening complications. Besides correcting hypokalemia and hypertension, finding the triggering factor for pseudohyperaldosteronism is essential to prevent recurrence. CASE DESCRIPTION: A 68-year-old Syrian man presented in the Emergency Department with complaints of fatigue, weakness and exercise-related shortness of breath. Blood tests revealed severe hypokalemia for which suppletion and cardiac rhythm surveillance was necessary. Talking to the patient's son, it occurred that our patient drank copious amounts of Erk Sous, a thirst-quenching drink made from liquorice. The diagnosis pseudohyperaldosteronismwas confirmed by a high level of glycyrrhetinic acid in the patient's urine. After correction of the hypokalemia, our patient recovered successfully. CONCLUSION: Erk Sous is a thirst-quenching drink that can cause pseudohyperaldosteronism. The drink is popular in the Middle East during summer and Ramadan. If a patient from the Middle East presents with hypokalemia and/or hypertension, ask for consumption of Erk Sous.

BACKGROUND: Pressure ulcers are a frequent complication of bed rest. We examined risk factors for hospital-acquired pressure ulcers, the use of preventive devices, and the impact of case-mix adjustments on between-ward comparisons. METHODS: We conducted 3 cross-sectional surveys in a teaching hospital of 2373 patients who had no pressure ulcer on admission. We assessed the presence of pressure ulcer, dates of admission and ulcer occurrence, hospital ward, patient age and sex, appetite and route of nutrition, surgery during stay, hospitalization for fracture, comorbidities, use of low-pressure devices (special mattresses, cushions, and pressure-reducing beds), and the Norton Pressure Ulcer Prediction score (physical condition, mental condition, activity, mobility, and incontinence). RESULTS: Two hundred forty-seven new pressure ulcers occurred (5.7 per 1000 person-days). In multivariate analysis, the risk for pressure ulcer increased with age (risk gradient across 5 categories was 1:4.5; P<.001) and Norton score (across 5 categories, risk gradient was 30-fold; P<.001); other risk factors (all relative risks, 1.5-1.8; P<.002) were hospitalization for fracture, surgical intervention, reduced appetite, and nasogastric tube or intravenous nutrition. Adjustment for case mix substantially modified differences between hospital wards. Use of preventive devices was associated with Norton score, but not all high-risk patients benefited. CONCLUSIONS: Pressure ulcers were seen in every 10th hospitalized adult. Patient age and Norton score were the strongest risk factors for pressure ulcers. Use of preventive devices was suboptimal. Adjustment for case mix is essential if pressure ulcer incidence is to be used as an indicator of quality of care.

PURPOSE: To compare the relative value of clinical variables with dobutamine-atropine stress echocardiography to predict cardiac events during long-term follow-up. Dobutamine stress echocardiography is increasingly used for the detection of coronary artery disease, but little is known of its prognostic value. PATIENTS AND METHODS: A total of 430 patients (310 men; mean age 61 years, range 22 to 90) were enrolled in the study. Patients were referred for chest pain complaints and were unable to perform an adequate exercise stress test. All patients underwent dobutamine-atropine stress test (incremental dobutamine infusion: 10 to 40 micrograms/kg/minute, continued with atropine 0.25 to 1 mg intravenously if necessary to achieve 85% of the age predicted maximal heart rate, without symptoms or signs of ischemia) and clinical cardiac evaluation. Follow-up was 17 +/- 5 months, with a minimum of 6 months; 3 patients were lost to follow-up. Cardiac events were defined as cardiac death, nonfatal myocardial infarction, and coronary revascularization. RESULTS: Seventy-nine cardiac events occurred in 76 patients: cardiac death (n = 11), nonfatal myocardial infarction (n = 18), and coronary revascularization (n = 50). By multivariate regression analysis, the prognostic value of the stress test in addition to common clinical variables was assessed. (1) Cardiac death was predicted by age greater than 70 years (odds ratio 5.6, 1.5 to 20) or new wall motion abnormalities in a study that is normal at rest (odds ratio 4.1, 1.1 to 15). (2) Death or myocardial infarction was predicted by a history of myocardial infarction (odds ratio 4.8, 1.8 to 13) or age greater than 70 years (odds ratio 2.3, 1.1 to 5.4), and the stress test outcome provided no additional information. (3) If all events were combined, only stress test results were prognostic: new wall motion abnormalities in a study that is normal at rest (odds ratio 3.1, 1.9 to 5.1), wall motion abnormalities at rest (wall motion score at rest > or = 1.12) (odds ratio 2.5, 1.4 to 4.0), or any new wall motion abnormalities during stress (odds ratio 2.0, 1.4 to 3.8). The positive predictive value of any new wall motion abnormality during stress for all late cardiac events was 25% (95% confidence interval [CI] 19 to 31) with a negative predictive value of 87% (95% CI 83 to 91). CONCLUSION: In a large cohort of unselected patients with chest pain syndromes, new wall motion abnormalities induced by dobutamine provide additional information for late cardiac events, independent of clinical variables.

We performed an observational cohort study to test the ability of a short-form screening procedure to detect unrecognized functional disability, as well as its capacity to predict clinical outcome. This screening procedure was administered to 198 consecutive patients within 48 hours of admission. Clinical outcomes upon discharge from the acute care hospital and at 3 months were analyzed according to the number of functional disabilities present on admission. This brief test identified a mean of 1.8 and a median of 1 previously unrecognized functional disabilities per patient. The presence of two or more functional disabilities on admission (48% of the study population) was significantly associated with a negative outcome upon discharge (relative risk = 1.73; CI, 1.33-2.25; p = 0.0001) and at 3 months after discharge (relative risk = 1.34; CI, 1.10-1.64; p = 0.003) confirming the reliability of the short-form screening procedure.

The objective of this study was to assess the respective frequency of planned and unplanned early readmissions after discharge from an internal medicine department, and to identify and compare risk factors for these two types of readmissions. Readmissions within 31 days of discharge were identified as planned or unplanned based on analysis of discharge summaries. Time-failure methods were used to describe the risk of readmissions over time and to assess relationships between patient and index stay characteristics and risk of readmission. Of 5828 patients discharged alive, 730 (12.5%) were readmitted within 31 days. There were slightly more planned than unplanned readmissions (393 vs. 337). The difference in time-to-event functions was significant (P=0.04). The risk of planned readmission was increased for men, younger patients, and for patients discharged with a diagnosis of coronary heart disease, cardiac arrhythmia, and neoplastic disease. Increased risk of unplanned readmission was associated with index length of stay longer than 3 days, an increased number of comorbidities, and with a diagnosis of neoplastic disease. Planned readmissions constitute more than half of early readmissions to our internal medicine department. Therefore, a crude readmission rate is unlikely to be a useful indicator of quality of care. Several patient characteristics influence the risk of unplanned readmission, suggesting that case-mix adjustments are necessary when readmission rates are compared between institutions or tracked over time.

OBJECTIVES: To assess the specific contribution to overall scale performance of each of the five items that constitute the Norton pressure ulcer prediction scale. DESIGN: A comparison of statistical models based on cross-sectional surveys of hospitalized patients. SETTING: An urban teaching hospital in Geneva, Switzerland. PARTICIPANTS: 2373 hospitalized patients who were free of pressure ulcers on admission. MEASUREMENTS: Norton scale items measuring activity, mobility, physical condition, mental condition, and incontinence on a 4-point scale were examined as predictors of stage 1 or greater pressure ulcers. RESULTS: A total of 245 new pressure ulcers occurred between admission and patient observation. After adjustment for other independent predictors in proportional hazards models, only the activity and mobility items remained associated significantly with the risk of pressure ulcer. A simplified 2-item scale was more strongly associated with pressure ulcer risk than was the classic 5-item Norton scale. CONCLUSIONS: Our study suggests that the activity and mobility items of the Norton scale are sufficient to express the risk of pressure ulcers in hospitalized patients. Confirmation of this finding in prospective studies is warranted.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an escalating problem in hospitals worldwide. The hospital reservoir for MRSA includes recognized and unrecognized colonized or infected patients, as well as previously colonized or infected patients readmitted to the hospital. Early and appropriate infection control measures (ICM) are key elements to reduce MRSA transmission and to control the hospital reservoir. OBJECTIVE: To describe the role of an expert system applied to the control of MRSA at a large medical center (1,600 beds) with high endemic rates. METHODS: The University Hospital of Geneva has an extended hospital information system (HIS), DIOGENE, structured with an open distributed architecture. It includes administrative, medical, nursing, and laboratory applications with their relational databases. Among available patient databases, clinical microbiology laboratory and admission-discharge-transfer (ADT) databases are used to generate computer alerts. A laboratory alert (lab alert) is printed daily in the Infection Control Program (ICP) offices, listing all patients with cultures positive for MRSA detected within the preceding 24 hours. Patients might be either newly detected patients colonized or infected with MRSA, or previously recognized MRSA patients having surveillance cultures. The ICP nurses subsequently go to the ward or call the ward personnel to implement ICM. A second alert, the "readmission alert," detects readmission to the hospital of any patient previously colonized or infected with MRSA by periodic queries (q 1 min) to the ADT database. The readmission alert is printed in the ICP offices, but also forwarded with added guidelines to the emergency room. RESULTS: During the first 12 months of application (July 1994 to June 1995), the lab alert detected an average of 4.6 isolates per day, corresponding to 314 hospital admissions (248 patients); the use of this alert saved time for the ICP nurses by improving work organization. There were 438 readmission alerts (1.2 alerts per day) over the study period; of 347 patients screened immediately upon readmission, 114 (33%) were positive for MRSA carriage. Delayed recognition of readmitted MRSA carriers decreased significantly after the implantation of this alert; the proportion of MRSA patients recognized at the time of admission to the hospital increased from 13% in 1993 to 40% in 1995 (P < .001). CONCLUSIONS: Hospital information system-based alerts can play an important role in the surveillance and early prevention of MRSA transmission, and it can help to recognize patterns of colonization and transmission.

BACKGROUND: The purpose of this prospective study was to evaluate the immediate and late outcome of acute left colonic diverticulitis and to correlate it with age (younger and older than 50 years of age), gender, and initial computed tomography (CT) findings. METHODS: Analysis was made of data collected prospectively from all patients admitted because of acute colonic diverticulitis between October 1986 and January 1992. Diagnosis relied on results of operation, CT, and Gastrografin enema. Two hundred twenty-six patients were urgently hospitalized for acute left colonic diverticulitis; 47 were younger than 50 years of age (21%). RESULTS: Sixty-six patients (29%) were operated on during their first hospitalization. The remaining 160 patients treated conservatively underwent CT and an enema within 72 hours of admission. Fifty-nine of 179 patients (33%) older than 50 years of age required operation during their first attack, compared with 7 in 47 patients (15%) younger than 50 years of age (p = 0.02), although on CT severe diverticulitis was found in 36 of 141 patients (26%) older than 50 years of age and in 16 of 43 patients (37%) younger than 50 years of age (p = 0.13). Of the 160 patients treated conservatively, 11 of 40 patients (28%) younger than 50 years of age experienced recurrences or complications after their first discharge, compared with 16 in 120 patients (13%) older than 50 years of age (p = 0.04). CONCLUSIONS: Patients younger than 50 years of age were significantly more prone to recurrences and complications after conservative treatment of their diverticulitis, whereas older patients required operation significantly more often during their first hospitalization.

During a 10-year period (1980 through 1989), 28,953 patients were admitted to our Clinic of Digestive Surgery, Geneva, Switzerland. Two thirds of them were operated on, and one third were treated conservatively. Symptomatic pulmonary embolism (PE) was recorded in 90 patients (0.31%; 95% confidence interval, 0.25% to 0.38%) during their hospital stay. Within 30 days of hospital discharge, 29 patients were readmitted because of PE (incidence of delayed PE, 0.10%; 95% confidence interval, 0.07% to 0.14%; total incidence of PE, 0.41%; 95% confidence interval, 0.34% to 0.49%). In the operated-on group, the delayed embolic events occurred a median of 6 days (range, 2 to 25 days) after discharge and 18 days (range, 6 to 35 days) after surgery. Delayed PEs were more frequent after so-called low-risk surgery. Thus, the rate of postoperative PE increased by 30% when PEs occurring within 30 days of hospital discharge were considered, and this provides a useful basis for prolonged prophylactic measures after hospital stay.

To examine the bioavailability of rifampicin formulations produced in Indonesia, we conducted a single-dose, double-blind, cross-over bioavailability study. Antituberculosis drugs from three Indonesian manufacturers and one international manufacturer were compared in 12 healthy Indonesian subjects. Out of three local manufacturers, two showed equal bioavailability compared to the reference standard, and one showed slightly lower bioavailability (ratio 0.86; 90% confidence interval 0.80-0.91) and substandard rifampicin content of drug preparations. Plasma rifampicin concentrations in this study were more than three-fold higher than concentrations recently found in tuberculosis patients in Indonesia, which suggests that unknown (disease-related) determinants may reduce the bioavailability of rifampicin formulations.

SETTING: Although rifampicin is a key drug in tuberculosis treatment, little is known about its quality and bioavailability in countries endemic for tuberculosis. High drug levels may lead to increased toxicity, while low drug levels may predispose to treatment failure and relapse. OBJECTIVE: To investigate possible variations in the bioavailability of plasma rifampicin in tuberculosis patients in Indonesia. DESIGN: Plasma concentrations of rifampicin and the rifampicin content of drug formulations in use were measured among 62 non-selected tuberculosis patients in Jakarta, Indonesia. RESULTS: Plasma concentrations of rifampin were generally low: 70% of patients had 2-hour plasma concentrations (Cmax) below 4 mg/L. No toxic plasma concentrations of rifampicin (>20 mg/L) were found. The strongest predictive factor for the magnitude of rifampicin concentrations was the drug manufacturer. The rifampicin content of the different drug preparations used was normal (90.5-103.6% of the reference standard). No association was found between low plasma rifampicin concentrations and delayed sputum conversion or treatment failure. CONCLUSION: The unexpectedly low plasma concentrations of rifampicin in this setting are most likely due to reduced bioavailability of local drug preparations, as the rifampicin content of the drug preparations was found to be normal. The clinical significance of these findings remains to be determined.

BACKGROUND: This prospective study was done to compare acute left-sided colonic diverticulitis in young patients (50 years of age or less) and older patients (more than 50 years of age) for severity of disease and immediate and late outcome. STUDY DESIGN: Of the 265 patients studied, 61 were 50 years of age or less; of these, 49 were men. In all instances, diagnosis was confirmed radiologically or histologically. RESULTS: Operations were performed less often upon younger patients than older patients (15 versus 33 percent, p = 0.001). Severe diverticulitis was found more often in younger men than older men (39 versus 23 percent). After successful conservative treatment during the first hospitalization period, younger men had a statistically greater risk of poor outcome than older men (29 versus 5 percent, p = 0.003). CONCLUSIONS: Although younger men have severe acute diverticulitis more often than older men, operative treatment during the first episode is less often needed. On the other hand, after conservative treatment, younger men have a statistically greater chance of poor secondary outcome than older men.

Patient histories, discharge summaries, and medical consultant reports are made up of written texts. Therefore, the gathering and archiving of these texts in machine-readable form has many characteristics of computer-based medical records. In Geneva, approximately 1,540 PCs are connected to the Hospital Information System DIOGENE 2, with the possibility of accessing all the functions offered by the system without losing any of their MS-DOS word processing capabilities. The UNIDOC system, presented in this paper, takes all these features into account, a real marriage of technologies between the MS-DOS environment and the distributed client-server architecture. The INGRES database management system supports the entire archiving process of the medical patient texts, structured by prelabelled paragraphs and automatically indexed. Both the quality and accessibility of the records are enhanced, while the archiving capacity is neither too limited nor too expensive.

Readmission rate is often used as an indicator for the quality of care. However, only unplanned readmissions may have a link with substandard quality of care. We compared two databases of the Geneva University Hospitals to determine which information is needed to distinguish planned from unplanned readmissions. All patients readmitted within 42 days after a first stay in the wards of the Department of Internal Medicine were identified. One of the databases contained encoded information needed to compute DRGs. The other database consisted of full-text discharge reports, addressed to the referring physician. Encoded reports allowed the classification of 64% of the readmissions, whereas full-text reports could classify 97% of the readmissions (p < 0.001). The concordance between encoded reports and full-text reports was fair (kappa = 0.40). We conclude that encoded reports alone are not sufficient to distinguish planned from unplanned readmissions and that the automation of detailed clinical databases seems promising.

ARCHIMED is a Network of Integrated Information Systems (NIIS). This novel concept of hospital information system has a major advantage over the currently used distributed systems. The normalized representation structure of its databases enable its Navigators to reach simultaneously not only the data coming from different hospital departments, laboratories, and other hospital facilities, but also the data from different hospitals associated in the network.

BACKGROUND/AIMS: Long-term outcome in surgery for chronic pancreatitis remains relatively unknown. METHODOLOGY: Between 1963 and 1993, we performed 123 pancreatic resections and 35 drainage procedures for severe chronic pancreatitis. We reviewed 131 patients with a mean follow-up of 48 months (4 months to 18 years). RESULTS: Actual 10-year survival was 82% for nonalcoholic patients and 51% for alcoholic pancreatitis. Pain was successfully treated in 71% with pancreatic resection and in 42% with drainage procedures (p<0.01). Although post-operative diabetes mellitus occurred in 56% of patients after pancreatic resection, long-term nutritional status was similar after pancreatic resection and drainage procedures. Weight gain could be observed in 75 patients (47%) and quality-of-life was good to excellent in 97 patients (74%). CONCLUSIONS: In conclusion, long-term survival was mainly conditioned by the etiology of the disease. Pancreatic resections were more successful in treating intractable pain than drainage and required fewer re-interventions. As presumed, resections were associated with a higher rate of diabetes mellitus, but this, however, had no impact on long-term nutritional status and quality-of-life.

Since its birth in 1978, DIOGENE, the hospital information system of Geneva University Hospital has been constantly evolving, with a major change in 1995, when migrating from a centralized to an open distributed architecture. For a few years, the hospital had to face health policy revolution with both economical constraints and opening of the healthcare network. The hospital information system DIOGENE plays a significant role by integrating four axes of knowledge: medico-economical context for better understanding and influencing resources consumption; the whole set of patient reports and documents (reports, encoded summaries, clinical findings, images, lab data, etc.), patient-dependent knowledge, in a vision integrating time and space; external knowledge bases such as Medline (patient-independent knowledge); integration of these patient-dependent and independent knowledge in a case-based reasoning format, providing on the physician desktop all relevant information for helping him to take the most appropriate adequate decision.

The DIOGENE hospital information system has been expanded with a centralized and integrated patient clinical database recording structured patient data. The objective is to provide a standardized framework for the building of future clinical databases and for the integration of existing heterogeneous ones. The combined 'across time view' and 'across departments view' generated from the integrated clinical data will enable an evolutionary view of the patient state, both across time and across medical specialties. For this purpose and to permit the communication and exchange of data, a new controlled vocabulary for representing clinical data has been created. The construction of this vocabulary is based on the international ICD classification, already being used in DIOGENE for encoding patient diagnosis and procedures. A new extension of the ICD is proposed for medical information that goes beyond diagnosis and procedures encoding. The building of a common clinical findings dictionary, recording the definition of clinical entities, is based on this newly developed clinical vocabulary. This process is incremental, manual and substantial.

Because of intrauterine foetal death at 35 weeks, parturition in a woman aged 35 years was induced by intravenous sulprostone. A few hours after its start she sustained a myocardial infarction for which she was treated. Coronary angiography 4 weeks later showed normal coronary arteries and good left ventricular function. Mild cardiovascular reactions such as bradycardia and mild hypotension are frequently observed adverse effects. In some instances, sulprostone can induce myocardial ischaemia. However, the possibility of a myocardial infarction is not mentioned in the product information of sulprostone. As there was an obvious temporal relationship and other causative factors were sufficiently excluded, the causal relation between the administration of sulprostone and the occurrence of myocardial infarction can be regarded as almost certain. Several experimental studies provide support for the hypothesis that coronary spasms play a major role in the pathophysiology of a myocardial infarction during the administration of sulprostone.
