Continuing, Withdrawing, and Withholding Medical Treatment at the End of Life and Associated Characteristics: a Mortality Follow-back Study. J Gen Intern Med 2020; 35:126-132. [PMID: 31654360 PMCID: PMC6957664 DOI: 10.1007/s11606-019-05344-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Revised: 04/18/2019] [Accepted: 08/22/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND Studies on forgoing treatment often ignore treatments that are continued until death. OBJECTIVE To investigate how often specific treatments are withdrawn or withheld before death and to describe the associated patient, physician, and care characteristics. DESIGN National mortality follow-back study in Switzerland in 2013/2014 using a standardized survey to collect information on the patient's end of life and demographics on the physician. PARTICIPANTS A random sample of adults who died non-suddenly without an external cause and who had met the physician completing the survey (N = 3051). MAIN MEASURES Any of nine specific treatments was continued until death, withdrawn, or withheld. KEY RESULTS In 2242 cases (84%), at least one treatment was either continued until death or withheld or withdrawn. The most common treatment was artificial hydration, which was continued in 23%, withdrawn in 4%, and withheld in 22% of all cases. The other eight treatments were withdrawn or withheld in 70-94% of applicable cases. The impact of physician characteristics was limited, but artificial hydration, antibiotics, artificial nutrition, and ventilator therapy were more likely to be withheld at home and in nursing homes than in the hospitals. CONCLUSIONS Large differences exist between care settings in whether treatments are continued, withdrawn, or withheld, indicating the different availability of treatment options or different philosophies of care. While certain patient groups are more likely to have treatment withheld rather than attempted, neither patient nor physician characteristics impact the decision to continue or withdraw treatment.

Cause of death coding in Switzerland: evaluation based on a nationwide individual linkage of mortality and hospital in-patient records. Popul Health Metr 2019; 17:2. [PMID: 30823920 PMCID: PMC6397486 DOI: 10.1186/s12963-019-0182-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Accepted: 01/28/2019] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Cause of death statistics are an important tool for quality control of the health care system. Their reliability, however, is controversial. Comparing death certificates with their corresponding medical records is implemented only occasionally but may point to quality problems. We aimed at exploring the agreement between information in the cause of death statistics and hospital discharge diagnoses at death. METHODS Selection of disease categories was based on ICD-10 Tabulation List for Morbidity and ICD-10 Mortality Tabulation List 2. Index cases were defined as deaths having occurred among Swiss residents 2010-2012 in a hospital and successfully linked to the Swiss National Cohort. Rare, external and ill-defined causes were excluded from comparison, leaving 53,605 deaths from vital statistics and 47,311 deaths from hospital discharge statistics. For 95% of individuals, respective information from the 2000 census could be retrieved and used for multiple logistic regression. RESULTS For 83% of individuals the underlying cause of death could be traced among hospital diagnoses and for 77% the principal hospital diagnosis among the cause of death information. Mirroring different evaluation of complex situations by individual physicians, rates of agreement varied widely depending on disease/cause of death, but were generally in line with similar studies. Multiple logistic regression revealed however significant variation in reporting that could not entirely be explained by age or cause of death of the deceased suggesting differential exploitation of available diagnosis information. CONCLUSION Substantial regional variation and lower agreement rates among socially disadvantaged groups like single, less educated, or culturally less integrated persons suggest potential for improving reporting of diagnoses and causes of death by physicians in Switzerland. Studies of this kind should be regularly conducted as a quality monitoring.

Medical end-of-life practices in Swiss cultural regions: a death certificate study. BMC Med 2018; 16:54. [PMID: 29673342 PMCID: PMC5909244 DOI: 10.1186/s12916-018-1043-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2017] [Accepted: 03/23/2018] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND End-of-life decisions remain controversial. Switzerland, with three main languages shared with surrounding countries and legal suicide assistance, allows exploration of the effects of cultural differences on end-of-life practices within the same legal framework. METHODS We conducted a death certificate study on a nationwide continuous random sample of Swiss residents. Using an internationally standardized tool, we sent 4998, 2965, and 1000 anonymous questionnaires to certifying physicians in the German-, French-, and Italian-speaking regions. RESULTS The response rates were 63.5%, 51.9%, and 61.7% in the German-, French-, and Italian-speaking regions, respectively. Non-sudden, expected deaths were preceded by medical end-of-life decisions (MELDs) more frequently in the German- than in the French- or Italian-speaking region (82.3% vs. 75.0% and 74.0%, respectively), mainly due to forgoing life-prolonging treatment (70.0%, 59.8%, 57.4%). Prevalence of assisted suicide was similar in the German- and French-speaking regions (1.6%, 1.2%), with no cases reported in the Italian-speaking region. Patient involvement was smaller in the Italian- than in the French- and German-speaking regions (16.0%, 31.2%, 35.6%). Continuous deep sedation was more frequent in the Italian- than in the French- and German-speaking regions (34.4%, 26.9%, 24.5%), and was combined with MELDs in most cases. CONCLUSION We found differences in MELD prevalence similar to those found between European countries. On an international level, MELDs are comparably frequent in all regions of Switzerland, in line with the greater role given to patient autonomy. Our findings show how cultural contexts and legislation can interact in shaping the prevalence of MELDs.

Medical end-of-life decisions in Switzerland 2001 and 2013: Who is involved and how does the decision-making capacity of the patient impact? Swiss Med Wkly 2016; 146:w14307.

Abstract
QUESTIONS UNDER STUDY In Switzerland, the prevalence of medical end-of-life practices had been assessed on a population level only once - in 2001 - until in 2013/14 an identical study was conducted. We aimed to compare the results of the 2001 and 2013 studies with a special focus on shared decision-making and patients' decision-making capacity. METHODS Our study encompassed a 21.3% sample of deaths among residents of the German-speaking part of Switzerland aged 1 year or older. From 4998 mailed questionnaires, 3173 (63.5%) were returned. All data were weighted to adjust for age- and sex-specific differences in response rates. RESULTS Cases with at least one reported end-of-life practice significantly increased from 74.5% (2001) to 82.3% (2013) of all deaths eligible for an end-of-life decision (p <0.001). In 51.2% there was a combination of at least two different end-of-life decisions in one case. In relation to discussion with patients or relatives and otherwise expressed preferences of the patient, 76.5% (74.5-78.4%) of all cases with reported medical end-of-life practice in 2013 (2001: 74.4%) relied on shared decision-making, varying from 79.8% (76.5-82.7%) among not at all capable patients to 87.8% (85.0-90.2%) among fully capable patients. In contrast to a generally increasing trend, the prevalence of end-of-life practices discussed with fully capable patients decreased from 79.0% (75.3-82.3%) in 2001 to 73.2% (69.6-76.0%) in 2013 (p = 0.037). CONCLUSIONS Despite a generally high incidence of end-of-life practices in Switzerland, there remains potential for further improvement in shared decision-making. Efforts to motivate physicians to involve patients and relatives may be a win-win situation.

Moving to and dying in a nursing home depends not only on health - an analysis of socio-demographic determinants of place of death in Switzerland. PLoS One 2014; 9:e113236. [PMID: 25409344 PMCID: PMC4237376 DOI: 10.1371/journal.pone.0113236] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2014] [Accepted: 10/22/2014] [Indexed: 11/18/2022] Open
Abstract
Background In developed countries generally about 7 out of 10 deaths occur in institutions such as acute care hospitals or nursing homes. However, less is known about the influence of non-medical determinants of place of death. This study examines the influence of socio-demographic and regional factors on place of death in Switzerland. Data and Methods We linked individual data from hospitals and nursing homes with census and mortality records of the Swiss general population. We differentiated between those who died in a hospital after a length of stay ≤2 days or ≥3 days, those who died in nursing homes, and those who died at home. In gender-specific multinomial logistic regression models we analysed N = 85,129 individuals, born before 1942 (i.e., ≥65 years old) and deceased in 2007 or 2008. Results Almost 70% of all men and 80% of all women died in a hospital or nursing home. Regional density of nursing home beds, being single, divorced or widowed, or living in a single-person household were predictive of death in an institution, especially among women. Conversely, homeownership, high educational level and having children were associated with dying at home. Conclusion Place of death substantially depends on socio-demographic determinants such as household characteristics and living conditions as well as on regional factors. Individuals with a lower socio-economic position, living alone or having no children are more prone to die in a nursing home. Health policy should empower these vulnerable groups to choose their place of death in accordance to needs and wishes.

Abstract
Background Prevalence estimates of chronic medical conditions and their multiples (multimorbidity) in the general population are scarce and often rather speculative in Switzerland. Using complementary data sources, we assessed estimates validity of population-based prevalence rates of four common chronic medical conditions with high impact on cardiovascular health (diabetes mellitus, hypertension, dyslipidemia, obesity). Methods We restricted our analyses to patients 15-94 years old living in the German speaking part of Switzerland. Data sources were: Swiss Health Survey (SHS, 2007, n = 13,580); Family Medicine ICPC Research using Electronic Medical Record Database (FIRE, 2010-12, n = 99,441); and hospital discharge statistics (MEDSTAT, 2009-10, n = 883,936). We defined chronic medical conditions based on use of drugs, diagnoses, and measurements. Results After a careful harmonization of the definitions, a high degree of concordance, especially regarding the age- and gender-specific distribution patterns, was found for diabetes mellitus (defined as drug use or diagnosis in SHS, drug use or diagnosis or blood glucose measurement in FIRE, and ICD-10 codes E10-14 as secondary diagnosis in MEDSTAT) and for hypertension (defined as drug use alone in SHS and FIRE, and ICD-10 codes I10-15 or I67.4 as secondary diagnosis in MEDSTAT). A lesser degree of concordance was found for dyslipidemia (defined as drug use alone in SHS and FIRE, and ICD-10 code E78 in MEDSTAT), and for obesity (defined as BMI ≥ 30 kg/m2 derived from self-reported height and weight in SHS, from measured height and weight or diagnosis of obesity in FIRE, and ICD-10 code E66 as secondary diagnosis in MEDSTAT). MEDSTAT performed well for clearly defined diagnoses (diabetes, hypertension), but underrepresented systematically more symptomatic conditions (dyslipidemia, obesity). Conclusion Complementary data sources can provide different prevalence estimates of chronic medical conditions in the general population. However, common age and sex patterns indicate that a careful harmonization of the definition of each chronic medical condition permits a high degree of concordance.

Abstract
Background The worldwide increase in obesity is becoming a major health concern. General practitioners (GPs) play a central role in managing obesity. We aimed to examine Swiss GPs self-reported practice in diagnosis and treatment of obesity with a special focus on the performance of waist measurement. Methods A structured self-reported questionnaire was mailed to 323 GPs recruited from four urban physician networks in Switzerland. Measures included professional experience, type of practice, obesity-related continuing medical education (CME) and practice in dealing with obesity such as waist measurement. We assessed the association between the performance of waist measurement and obesity-related CME by multivariate ordered logistic regression controlling for GP characteristics as potential confounders. Results A total of 187 GPs responded to the questionnaire. More than half of the GPs felt confident in managing obesity. The majority of the GPs (73%) spent less than 4 days in the last 5 years on obesity-related CME. More than half of GPs gave advice to reduce energy intakes (64%), intakes of high caloric and alcoholic drinks (56%) and to increase the physical activity (78%). Half of the GPs seldom performed waist measurement and documentation. The frequency of obesity-related CME was independently associated with the performance of waist measurement when controlled for GPs' characteristics by multivariate ordered logistic regression. Conclusions The majority of GPs followed guideline recommendations promoting physical activity and dietary counselling. We observed a gap between the increasing evidence for waist circumference assessment as an important measure in obesity management and actual clinical practice. Our data indicated that specific obesity-related CME might help to reduce this gap.

Abstract
OBJECTIVE Information on diabetes prevalence in the general population is scarce and often based on extrapolations. We evaluated whether prevalence could be estimated from routine data sources. RESEARCH DESIGN AND METHODS The sources were 1) hospital discharges (2008, n = 828,171), 2) death registry (2007/2008, n = 118,659), and 3) Swiss Health Survey (SHS; 2007, n = 18,665). Persons without diabetes as underlying cause of death (death registry) or principal diagnosis (hospital discharges) were regarded as surrogate for a general population random sample. RESULTS In those aged 20-84 years, 4.5% of men and 3% of women were expected to have diabetes. By source, estimations were 4.4 and 2.8% (hospital discharges), 3.8 and 3.1% (death registry), and 4.9 and 3.7% (SHS) for men and women, respectively. Among sources, age-sex patterns were similar. CONCLUSIONS In countries with adequate data quality, combination of routine data may provide valid and reliable estimations of diabetes prevalence. Our figures suggest that International Diabetes Federation extrapolations substantially overestimate diabetes prevalence in Switzerland.

Abstract
OBJECTIVE Very few studies specifically have examined the health status of 20-year-olds. The purpose of the present study is to examine the changes in health status and behaviour among young Swiss adults between 1993 and 2003. METHODS The present study used data from the Swiss Federal Surveys of Adolescents, conducted in 1993 and 2003 among 20-year-olds in Switzerland. The study sample included military recruits and a representative community cohort. More than 20,000 subjects participated in each survey. RESULTS Young adults in 2003 reported fewer traffic- and sports-related accidents, but more work-related and other accidents versus young adults in 1993. A greater percentage of men were overweight or obese in 2003. Also in 2003, a greater percentage of males and females regularly used alcohol, cigarettes and cannabis. In particular, the number that smoked cigarettes daily increased by almost 30% and daily cannabis users increased more than two-fold. Young adults reported higher rates of inter-personal violence and theft in 2003. Compared to 1993, in 2003 young adults were more likely to report a sense of coherence; they also had fewer thoughts of suicide, but a greater sense that life is meaningless. CONCLUSIONS Our study provides the first Swiss data comparing the health status of 20-year-olds a decade apart. The findings suggest a significant increase in substance use. Health prevention efforts among young adults ages 18-24 should focus on substance use. In addition, developing strategies to decrease interpersonal violence, delinquent behaviour, and obesity should be a major public health priority.

Abstract
BACKGROUND AND OBJECTIVE There have not been any comprehensive data from German-speaking countries on the medical practice of withholding or withdrawing treatment at the end of life. This study from the German-speaking part of Switzerland provides the first in-depth analysis in this field. This study is based on data from this region and is a contribution to a large empirical research project on medical end-of-life decisions in 6 European countries (EURELD). METHODS Continuous random samples (n = 4991) were taken from all deaths in the German-speaking part of Switzerland that had been reported to the Swiss Federal Office of Statistics between June and October 2001. Doctors who had been attending the deceased person were asked to complete mailed questionnaires, their replies being kept strictly anonymous. RESULTS The response rate was 67 %. Medications were withheld or withdrawn in 48 % of all treatments forgone: among these, antibiotics accounted for 17 %. Other potentially life-sustaining medical measures forgone included artificial hydration (12 %), surgery (7 %), artificial feeding (6 %), chemotherapy (6 %), diagnostic tests (4 %), hospital admissions (3 %), renal dialysis (2 %), blood product infusions (2 %), intubation (2 %), ventilation (2 %), resuscitation (2 %), and radiotherapy (1 %). 43 % of all treatments were forgone in patients who died in hospital, 42 % in nursing homes, and 15 % at home. In almost three-quarters (73 %) of the treatments forgone, a primary-care doctor had ordered the treatment to be withheld or withdrawn. On average, forgoing treatment led to a life-shortening effect of more than one month in 8 % of all cases. The proportion was higher for renal dialysis (25 %), blood products infusion (18 %), and diagnostic tests (16 %). CONCLUSIONS Forgoing life-sustaining medical treatment comprises a wide range of decisions taken in many different clinical settings. In most cases the likely lifespan is only slightly shortened.

Abstract
BACKGROUND Official information on the place of death has not been collected by the Swiss Federal Office of Statistics since 1987. Thus, no statements can be made for the developments in Switzerland. METHODS Physicians from the German speaking part of Switzerland who had filled in a death certificate between June 1 and October 30, 2001 were sent a questionnaire about circumstances of the specific death case. The frequencies of the place of death (at home, in hospital, in home for elderly, in nursing home, other place) were compared with the official data of the years 1969 until 1986. Using logistic regressions predictors for the place of death were estimated. RESULTS In 2001 in the German speaking part of Switzerland death occurred most frequently in hospital (37.2% of all death cases) followed by a home for elderly (33.5%) and dying at home (22.7%). Relevant predictors for the place of death were cause of death, sex, marital status and partly religion. Whereas between 1969 and 1986 a development towards dying in institutions was found, between 1986 and 2001 the place of death shifted within the institutions from hospitals to homes for elderly. CONCLUSION The relevance of the home for elderly as the place of death will further grow in the future. To allow people to fulfill the tasks of caring for their relatives at home the ambulant emergency services will have to be augmented and relatives have to be motivated and supported.

Abstract
The influence of four coping strategies ("rumination," "search for affiliation," "threat minimization," and "search for information"), four social network dimensions ("affectively positive," "affectively negative," "accepting confidants," and "liking confidants") and sociodemographics on the sexual risk behavior of HIV-infected persons were analyzed in sexual encounters with steady and casual partners. The analysis examines bi- and multivariately the predictors for sexual risk behavior. The study population consisted of 103 asymptomatic HIV-infected persons (80 men, 23 women, mean age 34 years, range 21-69 years) who participated in our prospective study and reported their sexual contacts during the previous 6 months. In sexual encounters with steady partners, the risk of unprotected behavior increased with the frequency of sexual contact. In these encounters, coping strategies and social network had no influence on sexual risk behavior. In sexual contacts with casual partners, the number of contacts with these partners was also of importance. The coping strategy "rumination" correlates significantly with enhanced risk behavior. In sexual contacts with casual partners, there was no correlation between sexual risk behavior and the three other coping strategies or social network. In multivariate analysis, the number of sexual contacts was the only significant predictor for sexual risk behavior with steady partners as well as casual ones. As sexual activity with HIV-infected persons is not absolutely safe, further prevention campaigns have to focus more on the motivation for safe sex, its situational aspects, and partners' responsibility.

Abstract
OBJECTIVES Preliminary assessment of the adequacy of AIDS surveillance efforts in Europe by comparing data from two official sources-AIDS surveillance and mortality statistics. METHODS The study used ENAADS (European Non-Aggregate AIDS Data Set) data compiled by the European Centre for the Epidemiological Monitoring of AIDS in St Maurice, France, and mortality statistics from WHO. As ENAADS provides information about AIDS incidence as well as AIDS mortality, both series were compared with WHO mortality data. Western European countries with more than 1000 adult AIDS cases as of July 1997 were included in the cross country comparative analyses. RESULTS AIDS surveillance and mortality statistics in Europe depict four different patterns: (1) high overall concordance (Austria, Italy, Switzerland); (2) concordance between incidence by ENAADS and mortality by WHO, but a delay in mortality reporting in ENAADS (France, Spain); (3) more cases in WHO mortality data than in ENAADS data (Germany, Portugal); (4) more cases in ENAADS data than in WHO mortality data (Sweden, United Kingdom, Greece, Belgium). CONCLUSIONS National AIDS surveillance systems in Europe exhibit important differences in terms of completeness and functionality. New challenges such as the introduction of effective but expensive and complex treatments will exert demands on surveillance efforts. Countries with discrepant AIDS and mortality data should try to improve and update their surveillance systems.

Abstract
A 85 year old female was hospitalized because of a bronchopulmonary infection. During the hospitalization she developed a progressive stupor. There was no sign of an intracerebral pathology, an electrolyte disorder, a new infection or a psychiatric diagnosis. Evaluation of the past history made a recently started digitalis medication responsible for the stupor. After discontinuation of digitalis the patient regained complete consciousness within two weeks. In the Holter-EKG we found once an asystole of four seconds duration without any symptoms.

Abstract
A 75-year old female underwent coronary angiography for chest pain. Significant proximal stenosis of the left coronary artery was found. During the waiting time for bypass surgery, intravenous heparin treatment was established for several days because of recurrent unstable angina pectoris. 10 days after coronary angiography an acute event with chest pain, hypotension, tachycardia and a new right bundle branch block suspect for myocardial infarction occurred, which was treated with rt-PA. Fever, persistent hypotension, acute progressive renal failure and thrombocytopenia suggested septic shock, and the patient was transferred to our hospital. A pulmonary artery catheter could not be advanced beyond the main stem of the pulmonary artery. The patient died suddenly 24 hours later from acute right ventricular failure. Autopsy demonstrated multiple white clots in both pulmonary arteries. The histological finding of clots rich in leukocytes and fibrin was compatible with the diagnosis of heparin-induced thrombosis-thrombocytopenia or white clot syndrome. Heparin-induced thrombocytopenia may occur after about 5 days of treatment. Two distinct types have been described. The first type occurs in up to 25% of patients receiving heparin and is a result of temporary platelet aggregation, margination and peripheral sequestration. The less common second type of thrombocytopenia is thought to be mediated by a heparin-dependent IgG antibody inducing platelet aggregation and may be associated with thromboembolic events leading to the white clot syndrome, which is rarely reported in the literature. In these cases heparin should be stopped immediately and replaced by oral anticoagulation. Other therapies such as low molecular weight heparin, synthetic heparinoids, hirudin, fibrinolytic agents, plasmapheresis and intravenous immunoglobulins are discussed. Monitoring of the platelet count every 5 days in patients receiving heparin for any extended period should become standard medical practice to avoid potential fatal complications.

Abstract
OBJECTIVES To analyse trends in age at diagnosis for adult AIDS cases reported in Europe and the United States. DESIGN We used AIDS surveillance data for the seven European countries with the highest cumulative number of AIDS cases reported through June 1994 and for the United States through June 1993. Mean age at AIDS diagnosis over time was calculated by sex, transmission category and country. Linear regression yielded annual increase in age and permitted statistical evaluation of the trends observed. Annual AIDS incidence was calculated for homo-/bisexual men and injecting drug users (IDU) by 5-year age groups over time. RESULTS We found an overall increase in age at AIDS diagnosis among the main transmission categories in Europe and the United States. The epidemiologic profiles of the two regions were highly similar, despite the lower average age among IDU in Europe compared with the United States (30.6 versus 36.7 years) and lower annual increases in age in the United States. In contrast to homo-/bisexual men, the increase in age at diagnosis is strikingly uniform and pronounced among IDU. Between 1986 and 1993, IDU in all countries exhibited at least a 6-month increase in age at diagnosis per annum. Although annual AIDS incidence remains consistent between various age groups of homo-/bisexual men, IDU aged 30-49 years show continuing increase, whereas their younger counterparts show signs of stabilization or decrease. CONCLUSIONS Despite different epidemic profiles and prevention policies, the age trends for the European countries examined and the United States were strikingly similar. The meaning of this general increase in age among the main transmission categories and the especially high increase among IDU may provide important insight into epidemic dynamics and intervention assessment.

The aesthetic guidelines of the mucogingival complex for fixed prosthodontics. PRACTICAL PERIODONTICS AND AESTHETIC DENTISTRY : PPAD 1996; 8:333-41; quiz 342.

Abstract
Until the 1980s, aesthetic dentistry focused its attention primarily on the replication and improvement of tooth structure by developing modifications of porcelain-fused-to-metal crown restorations, incorporated in porcelain systems in combination with adhesive technology. The introduction of new, improved, or modified periodontal surgical techniques addresses nearly all mucogingival challenges, except for the loss of papillae. Therefore, it is of critical importance to develop and define aesthetic guidelines for treatment of the mucogingival complex. In these guidelines, the aesthetic analysis of a treatment is divided into an evaluation of the mucogingiva and that of the tooth structure. Correction of mucogingival discrepancies is a prerequisite for aesthetic success in dental treatment. The learning objective of this article is to review the mucogingival discrepancies and examine a variety of potential solutions.

Abstract
We report the case of a 28-year-old-prostitute from Thailand with HIV infection stage B2 associated with retroperitoneal lymph node tuberculosis. 6 days after the beginning of anti-tuberculous therapy (isoniazid, rifampicin, pyrazinamid and ethambutol) the temperature rose to 40.5 degrees C, diarrhea, vomiting, and tachycardia developed and systolic blood pressure fell to 80 mm Hg. Liver function tests revealed acute hepatic failure (ALT 800 IU/l rising to 1500; serum bilirubin 89 mumol/l rising to 238.0; alkaline phosphatase 199 IU/l; glucose 1.8 mmol/l; prothrombin time 20%). Isoniazid, rifampicin, and pyrazinamid were replaced by streptomycin and PAS. A few days after withdrawal the liver profile returned to normal. Hours after the reintroduction of rifampicin total body erythema, pruritus, vomiting and severe hypotension developed, requiring saline methylprednisolone and epinephrine administration. The next reexposure to intravenous rifampicin produced a rash and was rapidly discontinued. Liver function tests remained normal. Later mild adverse reactions to streptomycin and pyrazinamid occurred, two drugs which had been well tolerated before. Subsequently the diagnosis of adrenal insufficiency was established. After initiation of steroid replacement (50 mg prednisolone) the antituberculous therapy with isoniazid, pyrazinamid and ethambutol was well tolerated. We conclude that the shock in this HIV-infected patient was either due to severe anaphylaxis to rifampicin or acute adrenal insufficiency ensuing on this drug. The reversible fulminant acute hepatic failure represents either an adverse effect of antituberculous drugs, especially hepatotoxic interactions of drug combinations, or an ischemic liver injury during hypotension caused by anaphylaxis. The case illustrates the complex nature of side effects of antituberculous drugs in HIV patients and their aggravation by adrenal insufficiency.

Abstract
HISTORY AND CLINICAL FINDINGS A 78-year-old woman had 4 years age received phenprocoumon as prophylaxis against thromboembolism after implantation of a left total knee prosthesis. Ten weeks later she developed hepatitis with negative hepatitis serology. 6 weeks before her latest hospitalisation a right total knee implantation had been performed and she again received phenprocoumon. She was admitted now because of cholestatic jaundice with rapid deterioration of her general state. There were no significant abnormal findings other than jaundiced skin and sclerae. INVESTIGATION Bilirubin concentration was clearly elevated to 11.5 mg/dl, and the transaminase activities were increased, together with raised gamma-GT and alkaline phosphatase levels. The Quick value was below 8%. Hepatitis serology was positive for hepatitis A antibodies, but negative for B and C antibodies. No antigens were demonstrated. The eosinophil count was elevated in the differential blood count. Sonography showed a normal-sized liver with slightly dense echo pattern, but no evidence of abscess or dilatation of the bile duct system. Liver biopsy revealed severe acute hepatitis of viral type and discrete eosinophilic infiltration. TREATMENT AND COURSE After all medication had been discontinued, transaminase activities decreased while bilirubin concentration rose. Thus, prednisone treatment was started (initially 50 mg/d), the dose then gradually reduced. The cholestasis parameters became normal and the patient's general state was much improved so that she could be discharged. CONCLUSION Cholestatic hepatitis is a rare side effect of phenprocoumon. The associated eosinophilia suggests the cause to be an allergic genesis in the sense of a hypersensitivity reaction.

Abstract
Stored serum samples of 20 patients with clinically and bioptically proven non-A, non-B hepatitis (NANBH) in the acute stage were tested for the presence of antibodies to hepatitis C virus (anti-HCV) by means of the Ortho ELISA system. After a mean period of 8 weeks from onset of the disease, 8 of 20 patients (40%) had anti-HCV. Our follow-up study included 14 patients. Of 9 primarily anti-HCV-negative patients, 2 became positive after 2 and 7 months respectively, whereas 7 patients remained anti-HCV-negative up to 52 months (range 1-128) after the onset of hepatitis. The prevalence of anti-HCV was 71% in 7 patients with parenteral hepatitis related to transfusions (n = 2) or drug abuse (n = 5), and 38% in 13 patients with sporadic NANBH. Of the 8 anti-HCV-negative patients with sporadic NANBH, 5 had stayed in one of the countries where enterically transmitted NANBH is endemic 3 to 6 weeks before the onset of their disease. Our results show that at present the anti-HCV-test supplies an etiologic basis for approximately half of all cases of NANBH in acute stage. Nevertheless, in most cases the acute NANBH remains a diagnosis of exclusion.

Abstract
We investigated intestinal permeability in healthy adult volunteers, and in patients with Crohn's disease, ulcerative colitis, idiopathic sprue and idiopathic hyperamylasemia by oral administration of 10 g low molecular weight polyethylene glycol (PEG-400) and quantitation of its renal excretion over the subsequent 6 hours by high performance liquid chromatography (gel permeation HPLC). The mean amount of PEG-400 excreted during the first 6 hours by the 12 patients with Crohn's disease (3.1 +/- 0.3 g, mean +/- SE) and the 8 patients with ulcerative colitis (2.6 +/- 0.3 g) was not significantly different from the amount excreted by the 24 healthy volunteers (2.9 +/- 0.1 g). The 3 patients with idiopathic sprue excreted significantly less (1.4 +/- 0.3 g, p less than 0.05) and the 3 patients with idiopathic hyperamylasemia significantly more (4.0 +/- 0.4 g, p less than 0.05) than the healthy controls. In conclusion, no alteration of intestinal permeability could be demonstrated in patients with Crohn's disease or ulcerative colitis. However, intestinal permeability was decreased in patients with idiopathic sprue and increased in those with idiopathic hyperamylasemia.

Abstract
Aluminium-containing phosphate binders were replaced by a calcium and magnesium carbonate-containing antacid in 20 patients on long-term haemodialysis, over a three-month period in all of them, for 12 months in ten. After two months the serum aluminium level fell (mean +/- SD) from 3.0 +/- 1.6 to 1.4 +/- 0.5 mumol/l (P less than 0.001). After three months the serum phosphate level had fallen from 1.8 +/- 0.4 to 1.5 +/- 0.4 mumol/l (P less than 0.05), while during the same period parathormone (PTH-NH2) fell from 1.4 +/- 1.4 to 0.8 +/- 0.7 ng/ml (P less than 0.05). Serum total calcium concentration rose after two months from 2.2 +/- 0.2 to 2.4 +/- 0.2 mmol/l (P less than 0.001). In a third of patients the uraemic acidosis was corrected, standard bicarbonate rising from 18 +/- 2 to 21 +/- 3 mmol/l (P less than 0.05). Serum pH, potassium, sodium, magnesium and alkaline phosphatase did not change significantly. Hypercalcaemia was an expected disadvantage: repeated symptom-free episodes of hypercalcaemia occurred in six of 20 patients during the first three months and in a further two up to 12 months. These episodes were successfully controlled by a reduction of CaCO3/MgCO3 dosage and readministration of Al(OH)3. Extraosseous calcifications were not observed.

Abstract
In order to find an alternative antimicrobial treatment for childhood bacterial meningitis 30 infants and children with meningitis, due to Haemophilus influenzae (n = 13), Neisseria meningitis (n = 9), Streptococcus pneumoniae (n = 5), or meningitis of unknown aetiology (n = 3), were treated with cefuroxime, 200 mg/kg a day, as the only antibiotic. Prompt clinical and bacteriological responses were noted and every patient was cured. Cefuroxime concentrations in cerebrospinal fluid ranged from 1.1 to 18.8 (mean 7.0) mg/l at the beginning and from 0.5 to 4.1 (mean 1.6) mg/l at the end of treatment. Three infants developed symptomatic sterile subdural effusions which were managed by repeated subdural aspirations while still on antibiotics. Cefuroxime concentrations in the subdural fluid ranged from 17.4 to 32.4 mg/l. At follow-up 2 patients had moderate unilateral hearing loss and one had mild ataxia. We conclude that cefuroxime is effective and safe for the treatment of childhood bacterial meningitis caused by any of these common organisms.

Abstract
A causal relation between the enzyme, adenosine deaminase (ADA), and immune dysfunction is well known: patients with congenital inactivity of ADA invariably suffer of severe combined immunodeficiency. In contrast, we found in patients treated with immunosuppressive drugs increased ADA enzyme activity. Previous findings on ADA activity in acute leukemias are until now controversial. We found normal to increased ADA activity in children with acute lymphatic leukemia (ALL) and acute myeloid leukemia (AML) in remission as long as they were treated with cytostatic drugs. In the group of cured leukemics (in continuous remission after suspension of the therapeutic regimen) the ADA activities were normal. These findings do not exclude a heterogeneity within the leukemia group. They do not explain the signs of cellular immunodeficiencies well known in patients with acute leukemias.

Abstract
By reporting a further case attention is drawn to the autosomal recessive inherited DIDMOAD-syndrome. While diabetes mellitus and optic atrophy are easy to recognize, one often has specifically to look for deafness, diabetes insipidus and the frequently associated dilatation of the urinary tract. Awareness of this condition is important for genetic counselling and vocational guidance, and allows to avoid invasive neuroradiological investigations.
