Abstract
Patients with multimorbidity increasingly impact healthcare systems, both in primary care and in hospitals. This is particularly true in Internal Medicine. This population associates with higher mortality rates, polypharmacy, hospital readmissions, post-discharge syndrome, anxiety, depression, accelerated age-related functional decline, and development of geriatric syndromes, amongst others. Internists and Hospitalists, in one of their roles as Generalists, are increasingly asked to attend to these patients, both in their own Departments as well as in surgical areas. The management of polypathology and multimorbidity, however, is often complex, and requires specific clinical skills and corresponding experience. In addition, patients' needs, health-care environment, and routines have changed, so emerging and re-emerging specific competences and approaches are required to offer the best coordinated, continuous, and comprehensive integrated care to these populations, to achieve optimal health outcomes and satisfaction of patients, their relatives, and staff. This position paper proposes a set of emerging and re-emerging competences for internal medicine specialists, which are needed to optimally address multimorbidity now and in the future.

Abstract
BACKGROUND Multimorbidity increases healthcare resource utilization. Little is known on specific comorbidity combinations. AIMS To identify comorbidities associated with increased resource utilization among inpatients admitted for gastrointestinal bleeding (GIB). METHODS This retrospective cross-sectional study, 1/2010-5/2018 at the University Hospital Zurich, Switzerland, analyzed electronic health records of patients with upper (UGIB) and lower (LGIB) GIB, focusing on length of stay (LOS) and 30-day readmissions for resource use and clinical outcomes, investigated by multivariable regression adjusted for antithrombotics. RESULTS Of 1101 patients, 791 had UGIB and 310 LGIB, most often melena and bleeding diverticula, respectively. In UGIB, thromboembolic events showed a trend toward 27% increased LOS (1.27; 95% confidence interval [CI] 1.00-1.61), antithrombotics independently associated with 46% increased LOS (1.46; 95% CI 1.32-1.62). Cancer (odds ratio [OR] 2.86; 95% CI 1.68-4.88) independently associated with 30-day readmissions, anemia showed a trend (OR 1.68; 95% CI 1.00-2.84). In LGIB, none of the investigated comorbidities associated with increased LOS, but antithrombotics independently associated with 25% increased LOS (1.25; 95% CI 1.07-1.46). Atrial fibrillation/flutter (OR 2.69; 95% CI 1.06-6.82) and cancer (OR 4.76; 95% CI 1.40-16.20) associated strongly with 30-day readmissions. CONCLUSIONS In both groups, cancer associated with 30-day readmissions, antithrombotics with increased LOS. Thromboembolic events and anemia showed clinically important trends in UGIB. Atrial fibrillation/flutter associated with 30-day readmissions in LGIB. Prospective studies are needed to investigate these complex multimorbid populations and establish appropriate guidelines.

Abstract
The neural response in the human visual system is composed of magno-, parvo- and koniocellular input from the retina. Signal differences from functional imaging between health and individuals with a cognitive weakness are attributed to a dysfunction of a specific retinal input. Yet, anatomical interconnections within the human visual system obscure individual contribution to the neural response in V1. Deflections in the visual evoked potential (VEP) arise from an interaction between electric dipoles, their strength determined by the size of the neural population active during temporal - and spatial luminance contrast processing. To investigate interaction between these neural responses, we recorded the VEP over visual cortex of 14 healthy adults viewing four series of windmill patterns. Within a series, the relative area white in a pattern varied systematically. Between series, the number of sectors across which this area was distributed doubled. These patterns were viewed as pattern alternating and on-/off stimuli. P100/P1 amplitude increased linearly with the relative area white in the pattern, while N135/N1 and P240/P2 amplitude increased with the number of sectors of which the area white was distributed. The decreases P100 amplitude with increasing number of sectors is attributed to an interaction between electric dipoles located in granular and supragranular layers of V1. Differences between the VEP components obtained during a pattern reversing display and following pattern onset are accounted for by the transient and sustained nature of neural responses processing temporal - and spatial luminance contrast and ability of these responses to manifest in the VEP.

Abstract
BACKGROUND Little is known about the impact of depression across a broad range of multimorbid patients hospitalized for reasons other than depression. The objective of the study was to investigate in a large sample of multimorbid inpatients whether ancillary depression is associated with increased length of stay (LOS) and readmissions, two important clinical outcomes with implications for healthcare utilization and costs. METHODS We retrospectively analyzed a cohort of 253,009 multimorbid inpatients aged ≥18 at an academic medical center, 8/2009-8/2017. PRIMARY OUTCOME LOS. SECONDARY OUTCOMES LOS related to different main diagnoses, readmissions within 1, 3, 6, 12, and 24-months after discharge. RESULTS Multivariable linear regression showed 24% longer LOS in patients with ancillary depression (1.24; 95% confidence interval [CI]: 1.22, 1.25). Females stayed 22% longer (1.22; 95% CI: 1.20, 1.25), males 24% (1.24; 95% CI: 1.22, 1.27). We identified 16 main diagnosis clusters in which ancillary depression was associated with significant LOS increases, with associations being strongest for "Failure and rejection of transplanted organs and tissues", "Other noninfective gastroenteritis and colitis", and "Other soft tissue disorders, not elsewhere classified". Multivariable logistic and Poisson regression showed independent associations of ancillary depression with increased readmission odds and frequencies at 1, 3, 6, 12, and 24 months. CONCLUSIONS Ancillary depression was independently associated with increased LOS and more readmissions across a broad range of multimorbid inpatients.

Abstract
About 20-25% of all persons and about 90% of all patients who are acutely hospitalized in internal medicine departments have multiple acute or chronic diseases. They are multimorbid. The encounter with multimorbid patients has become the most common situation in the health care system. Theoretically, multimorbidity results in an innumerable potential disease constellations. In addition, the likelihood of interactions between diseases (disease-disease interactions, DDI) and the complexity increases overproportionately with each additional disease. However, multimorbidity often occurs in typical diadic, triadic, or higher characteristic combinations, in "disease clusters", e. g., vascular risk factors, heart and lung diseases, Frailty and dementia, psychiatric and somatic disorders. Such combinations lead to a worsening of the overall prognosis. In addition, DDIs are often difficult to treat or are life-threatening. Examples of DDIs include the following: anticoagulation and simultaneous severe bleeding, pain treatment and hypertension or renal insufficiency, depression and reduced medication adherence, chronic obstructive pulmonary disease and depression, Frailty and neurodepressant drugs and frequent falls, and combined psychiatric and somatic disorders. Such DDIs are common. Nevertheless, there are few studies and clinical guidelines that address these issues. The care of multimorbid patients is, therefore, heavily reliant upon guidelines developed mostly for single diseases. However, multimorbidity and serious DDIs are usually not addressed in these. Clinical guidelines can thus inadvertently jeopardize the safety of persons suffering from multiple diseases. In addition, stressful dilemmas arise for physicians encountering DDIs because of difficult treatment decisions.

Abstract
INTRODUCTION Whether clinical prediction rules for pulmonary embolism are accepted and used among general internal medicine residents remains uncertain. We therefore evaluated the frequency of use and acceptability of the Revised Geneva Score (RGS) and the Pulmonary Embolism Severity Index (PESI), and explored which factors were associated with rule use. MATERIALS/METHODS In an online survey among general internal medicine residents from 10 Swiss hospitals, we assessed rule acceptability using the Ottawa Acceptability of Decision Rules Instrument (OADRI) and explored the association between physician and training-related factors and rule use using mixed logistic regression models. RESULTS The response rate was 50.4% (433/859). Overall, 61% and 36% of the residents reported that they always or regularly use the RGS and the PESI, respectively. The mean overall OADRI score was 4.3 (scale 0-6) for the RGS and 4.1 for the PESI, indicating a good acceptability. Rule acceptability (odds ratio [OR] 6.19 per point, 95% confidence interval [CI] 3.64-10.51), prior training in emergency medicine (OR 5.14, CI 2.20-12.01), and availability of internal guidelines recommending RGS use (OR 4.25, CI 2.15-8.43) were associated with RGS use. Rule acceptability (OR 6.43 per point, CI 4.17-9.92) and rule taught at medical school (OR 2.06, CI 1.24-3.43) were associated with PESI use. CONCLUSIONS The RGS was more frequently used than the PESI. Both rules were considered acceptable. Rule acceptability, prior training in emergency medicine, availability of internal guidelines, and rule taught at medical school were associated with rule use and represent potential targets for quality improvement interventions.

Abstract
The Metabolic Syndrome is characterised by the following components: atherogenic dyslipidemia, elevated blood pressure, elevated glucose and abdominal obesity. 22% of 415 patients of an outpatient clinic in internal medicine fulfilled the criteria of a Metabolic Syndrome. The most common components were abdominal obesity, elevated blood pressure and elevated triglyceride. Only one in five treating physicians diagnosed a Metabolic Syndrome. Our data show that the concept of the Metabolic Syndrome has limited utility in clinical practice.

Abstract
Better understanding of epidemiology and pathophysiology of arterial hypertension has resulted in new definitions of blood pressure levels and treatment targets. The main reason for worldwide modest outcomes in the treatment of hypertension is suboptimal drug treatment including incomplete dose titration and an inadequate antihypertensive drug combinations. New techniques such as teletransmission of home blood pressure measurement together with ambulant 24-hour-blood-pressure-monitoring could serve as a solution to provide the physician the opportunity for an adequate antihypertensive therapy, in order to improve drug compliance and to shorten the time until reaching optimal blood pressure.

Abstract
A forty year old patient was referred by the federal insurance for medical assessment. His presenting complaint was chronic fatigue. The patient had been an intravenous drug user for years and had been infected with hepatitis C. He was treated with interferon. The patient history showed that he also suffered from anaemia and depression. He participated in a methadone substitution program. Our diagnostic procedures showed that he also has Hashimoto's thyroiditis.

Abstract
We report on a 41-year-old patient admitted for refractory arterial hypertension that had developed after a curative chemotherapy regimen due to seminoma stadium IIb four years ago. After exclusion of secondary forms of arterial hypertension (actually unsuccessfully treated with 5 different antihypertensive drugs) we performed a controlled medication intake-trial in our outpatient clinic. 90 minutes after taking the pills the patient complained of dizziness and perspiration while hypotension and bradycardia were measured simultaneously. Due to the difficult psychosocial situation (conflicts with the insurance and in the family, financial problems) and the suspected narcisstic personality disorder the issue of the proven malcompliance was not openly discussed in order to preserve the patient-doctor alliance. The antihypertensive regimen was then reduced to a double regimen. In the second part of the article the most common reasons for refractory arterial hypertension, especially the problem of treatment malcompliance, are summarized.

Abstract
A growing body of evidence supports or rejects preventive interventions in asymptomatic adults. Thus, counseling for smoking cessation and some immunizations have been shown to be cost-effective. Evidence supports screening for body weight (obesity), hypertension, hyperlipidemia, cervical cancer, colorectal cancer and breast cancer. Screening for lung, pancreatic and ovarian cancer has no effect on outcome and should not be performed. Controversial preventive interventions include general screening for diabetes mellitus in the young adult, thyroid disorders and prostate cancer. Physicians should be aware of a possible hidden agenda in patients presenting for a check-up.

Abstract
Migration, particularly among refugees and asylum seekers, poses many challenges to the health system of host countries. This study examined the impact of migration history on illness experience, its meaning and help-seeking strategies of migrant patients from Bosnia and Turkey with a range of common health problems in general practice in Basel, Switzerland. The Explanatory Model Interview Catalogue, a data collection instrument for cross-cultural research which combines epidemiological and ethnographic research approaches, was used in semi-structured one-to-one patient interviews. Bosnian patients (n=36) who had more traumatic migration experiences than Turkish/Kurdish (n=62) or Swiss internal migrants (n=48) reported a larger number of health problems than the other groups. Psychological distress was reported most frequently by all three groups in response to focussed queries, but spontaneously reported symptoms indicated the prominence of somatic, rather than psychological or psychosocial, problems. Among Bosnians, 78% identified traumatic migration experiences as a cause of their illness, in addition to a range of psychological and biomedical causes. Help-seeking strategies for the current illness included a wide range of treatments, such as basic medical care at private surgeries, outpatients department in hospitals as well as alternative medical treatments among all groups. Findings provide a useful guide to clinicians who work with migrants and should inform policy in medical care, information and health promotion for migrants in Switzerland as well as further education of health professionals on issues concerning migrants health.

Abstract
The introduction of Angiotensin II receptor blockers (ARB) in 1995 was another milestone in the pharmacological management of hypertension. Due to the manifold effects on several target organs Angiotensin II is one of the most important mediator in the pathogenesis of hypertension. The blockade of the Angiotensin II receptor type 1 is a crucial cornerstone in interrupting the pathophysiological pathways in hypertension. Furthermore ARB have an excellent tolerability comparable with placebo. In the last decade large placebo-controlled trials could prove the efficiency of ARB in terms of morbidity and mortality. Patients after acute myocardial infarction and patients with chronic heart failure benefit from treatment with ARB equally compared to treatment with ACE inhibitors. Combining ARB and ACE inhibitors in patient after myocardial infarction increases the rate of adverse events without improving survival. Increase of microalbuminuria and worsening of diabetic nephropathy is reduced by ARB in patients with diabetes type 2, but an advantage over ACE inhibitors could not be documented. Hypertensive patients with electrocardiographically left ventricular hypertrophy treated with ARB seem to have an additional benefit in terms of morbidity and mortality compared to treatment with beta-blockers. In the early treatment of stroke patients treated with ARB have a lower 12-mounth mortality than patients receiving placebo. In conclusion, Angiotensin II receptor blockers are due to their well proved efficiency, the cardio- and renoprotective qualities and the excellent tolerability profile a useful therapeutic option in the management of patients with hypertension.

Abstract
Die europäischen und amerikanischen Guidelines empfehlen bei hypertensiven Diabetikern einen Blutdruckzielwert <130/80mmHg in der Praxisblutdruckmessung. Dies gilt insbesondere für Patienten mit Endorganschäden oder sonstigen Hinweisen für hohes Risiko. Alle antihypertensiven Substanzklassen senken bei Hypertonikern mit Diabetes mellitus Typ 2 die Inzidenz von kardiovaskulären Ereignissen. ACE-Hemmer oder Angiotensin II-Rezeptorantagonisten sind bei Hinweisen auf Endorganschäden, insbesondere bei Mikroalbuminurie/Proteinurie oder linksventrikulärer Hypertrophie, zu bevorzugen.

Abstract
This study assesses the diagnostic accuracy of transferrinuria and an albumin-specific dipstick assay for detection of renal target organ damage (microalbuminuria) in hypertensive patients in a general practice setting. A spot urine sample of 130 nondiabetic patients with elevated office blood pressure readings (>140 and/or 90 mmHg) was investigated by measuring albumin to creatinine ratio (ACR) and transferrin to creatinine ratio (TCR) and by using an albumin-specific dipstick test (Micral). ACR was considered as comparative gold standard. TCR was elevated (>0.19 mg/mmol) in 26 urine samples (20.0% of the test samples). ACR was raised in 29 samples (22.3% of the test samples). Elevated TCR had a sensitivity of 97% and specificity of 91% for detection of microalbuminuria. Positive predicting value for microalbuminuria was 65%; negative predicting value was 99%. Correlation between ACR and TCR was strong (r=0.96). Dipstick testing for albumin was positive in 23 urine samples (17.7% of the test samples), 27 (20.8%) tests were false positive and six (4.6%) false negative. When dipstick was positive, the sensitivity of detecting microalbuminuria was 79%, and specificity 73%. In conclusion, detection of urinary transferrin in nondiabetic patients with hypertension is strongly associated with urinary albumin excretion. However, assessment of TCR does not identify additional patients with microalbuminuria compared to measurement of ACR alone. The semiquantitative Micral test offers a simple and valuable method to screen hypertensive patients for microalbuminuria in a primary care setting.

Abstract
In patients without target organ damage, a pharmacological antihypertensive therapy can be initiated with a monotherapy or a low dose combination therapy. A monotherapy often suffices to control blood pressure in patients with mild hypertension (140-159 mmHg systolic or 90-99 mmHg diastolic). In order to select the blood pressure-lowering drug that is best suited for an individual, monotherapies should be sequentially rotated, because it cannot be predicted to which drug a patient will best respond. Early initiation of a combination therapy is a good alternative. Theoretically, almost any of the six commonly used groups of antihypertensive drugs (ACE-Inihibitors, Angiotensin II-Receptor Antagonists, Beta-blockers, Calcium antagonists, Diuretics and Alpha blockers) can be combined with each other. However, combinations of Thiazid diuretics with inhibitors of the Renin-Angiotensin-Aldosteron-System (Beta blockers, ACE-Inhibitors, Angiotensin II-Receptor blockers) have proven most useful.

Abstract
Patients with essential arterial hypertension either have or do not have compelling reasons for specific drug classes. Patients lacking a compelling reason for a specific drug class are those without target organ damage (e.g. left ventricular hypertrophy, microalbuminuria, proteinuria, atherosclerosis) and without comorbidities. In these patients antihypertensive treatment can be initiated with Diuretics and perhaps Betablockers. Calciumantagonists, ACE-Inhibitors and Angiotensin II-Receptorenblockers (Sartans) are unlikely to be superior. However, adverse effects, patient preferences and antihypertensive efficacy of a drug in the particular individual ultimately determine the "choice" of the medication. In patients with a compelling reason for an individual drug class, i.e., in patients with target organ damage (e.g. left ventricular hypertrophy, microalbuminuria, proteinuria) or very high cardiovascular risk (e.g. Diabetes) Angiotensin II-Receptorblockers or ACE-Inhibitors should be used initially. In many hypertensives blood pressure will normalize in response to a combination therapy only. Usually, addition of a low dose thiazide to another drug class is the most beneficial combination. In most patients resistant to therapy, a 24-h-ambulatory blood pressure measurement to exclude white coat hypertension or a white coat component, evaluation of medication compliance, non-pharmacological measures and the tailored use of diuretics and other optimizations of therapy will lead to success.

Abstract
Hypertensive emergencies are acute, life-threatening events, characterised by high blood pressure and concomitant acute hypertensive target organ damage. These patients need immediate lowering of blood pressure mostly with parenteral drugs in the range of the autoregulative capacity of organ circulation and in-hospital monitoring of the vital functions. Hypertensive urgencies are not necessarily life-threatening, but persistence of high blood pressure may lead to acute target organ damage. Blood pressure should be lowered within 24 to 48 hours. Oral therapy is normally sufficient and hospitalisation is rarely necessary, but maintenance of antihypertensive therapy outside the hospital has to be ascertained.

Abstract
BACKGROUND Epidemiological studies have shown that increased arterial stiffness and wave reflections, major determinants of systolic and pulse pressure, are associated with morbidity and mortality. Therapeutic trials based on cardiovascular mortality have recently shown that reduction of systolic blood pressure (SBP) requires normalization of both large-artery stiffness and wave reflections. AIMS To compare the antihypertensive effects of the very-low-dose combination of perindopril (2 mg) and indapamide (0.625 mg) (one or two tablets per day) with the beta-blocking agent atenolol (50 mg; one or two tablets per day) in order to determine whether the combination decreased SBP and pulse pressure more than did atenolol, and whether this decrease occurred in relation to a reduction in arterial stiffness [aortic pulse wave velocity (PWV)] or a decrease in the intensity of, or delay in, wave reflections (augmentation index, measured by applanation tonometry) or a combination of both. MATERIAL AND METHODS This was a double-blind randomized study in 471 individuals with essential hypertension followed for 12 months. Arterial pressure was measured in the brachial artery (mercury sphygmomanometer) and in the carotid artery (applanation tonometry). RESULTS For the same reduction in diastolic blood pressure (DBP), the combination of perindopril and indapamide decreased brachial SBP and pulse pressure significantly more than did atenolol (adjusted differences between groups -6.2 +/- 1.5 and -5.5 +/- 1.0 mmHg, respectively; P < 0.001). This difference was even more pronounced for the carotid than for the brachial artery. Whereas both antihypertensive agents similarly decreased PWV, only the combination significantly attenuated wave reflections. CONCLUSION Normalization of SBP, pulse pressure and arterial function--a haemodynamic profile known to improve survival significantly in hypertensive populations at high cardiovascular risk--was achieved to a greater extent with a very-low-dose combination of perindopril and indapamide than with atenolol.

Abstract
OBJECTIVES To prospectively compare compliance with treatment in patients with hypertension responsive to treatment versus patients with treatment resistant hypertension. DESIGN Prospective case-control study. SETTING Outpatient department in a large city hospital in Switzerland, providing primary, secondary, and tertiary care. PARTICIPANTS 110 consecutive medical outpatients with hypertension and taking stable treatment with at least two antihypertensive drugs for at least four weeks. MAIN OUTCOME MEASURES Treatment compliance assessed with MEMS devices; blood pressure determined by 12 hour daytime ambulatory monitoring (pressure <135/85 mm Hg in patients aged =60 years and <155/90 mm Hg in patients aged >60 indicated hypertension responsive to treatment). RESULTS Complete data were available for 103 patients, of whom 86 took >/=80% of their prescribed doses ("compliant") and 17 took <80% ("non-compliant"). Of the 49 patients with treatment resistant hypertension, 40 (82%) were compliant, while 46 (85%) of the 54 patients responsive to treatment were compliant. CONCLUSION Non-compliance with treatment was not more prevalent in patients with treatment resistant hypertension than in treatment responsive patients.

Abstract
BACKGROUND Case-management programs for secondary prevention of coronary artery disease that utilize extensive resources can reduce cardiovascular risk factors, but less intensive approaches have failed to show benefits. This randomized trial evaluated whether a medium intensity case-management program improves risk factor control in patients with coronary artery disease. METHODS We assigned 201 consecutive patients hospitalized for acute coronary events in the intensive care unit of University Hospital, Basel, Switzerland, to either a risk factor case-management program (n = 99) or care as usual (n = 102) using the patients' primary care physicians as the unit of randomization (cluster randomization). The case-management program consisted of an hour of counseling by a clinician during hospitalization and two short reminders by phone and mail 3 and 6 months later. Treatment decisions were left to patients and their primary care physicians. RESULTS After 9 and 18 months of follow-up, there were no significant differences in lipid values, blood pressure control, fasting blood glucose, body-mass index, or number of smokers between the two groups. However, significantly more patients in the intervention group than in the care as usual group achieved target cholesterol values after 18 months (48% versus 27%, P = 0.002 and remained significant after Bonferroni-Holms correction) but not after 9 months of follow-up (31% versus 27%, P >0.2). CONCLUSION This hospital-based case-management and outreach program, limited to counseling by a clinician, did not substantially improve cardiovascular risk factor control among patients hospitalized for coronary events.

Abstract
BACKGROUND Angiogenesis plays a pivotal role in many processes. Here, we studied whether angiogenesis to basic fibroblast growth factor (bFGF) in normal and portal hypertensive rats requires nitric oxide (NO). METHODS To measure angiogenesis in vivo, two Teflon rings filled with collagen I (Vitrogen 100) were fixed in the mesenteric cavity at day 0, with one supplemented with bFGF (100 ng). Portal hypertension was induced by partial portal vein ligation (PVL). Sham-operated rats served as controls (CON). The role of NO was tested by adding the NO formation antagonist N(omega)-nitro-L-arginine (NNA; 3.3 mg/kg per day) to the drinking water. After 16 days, rings were explanted and embedded, and vessels were morphometrically counted. RESULTS bFGF significantly stimulated vessel formation per implant in CON rats (from 624 +/- 97 without stimulation to 1123 +/- 171, n = 11, P < 0.01), but not in PVL rats (from 1106 +/- 174 without stimulation to 1046 +/- 202, n = 9). Without stimulation, numbers of ingrown vessels were significantly (P < 0.05) higher in PVL compared to CON rats. NNA substantially inhibited angiogenesis in both groups (P < 0.01). Vessel numbers were 202 +/- 124 for PVL (n = 5) and 197 +/- 14 for CON (n = 5) animals. bFGF did not reverse angiogenesis prevented by NNA (373 +/- 98 for PVL, 265 +/- 26 for CON, n = 5 per group, NS). CONCLUSIONS NO formation inhibition diminishes both unstimulated and bFGF-stimulated angiogenesis in CON rats. Moreover, bFGF cannot rescue NNA-inhibited angiogenesis in PVL rats.

Abstract
AIMS To evaluate accuracy of patient-reported home blood pressure measurements (HBPM) when compared to real HBPM and their agreement with 12-h daytime ambulatory blood pressure monitoring (ABPM). MAJOR FINDINGS Self-reported HBPM were compared to stored values of a fully automated, oscillometric blood pressure monitor with integrated memory device and 12-h daytime ambulatory monitoring in 54 patients. In most patients (n = 46, 85%) mean reported systolic or diastolic versus real HBPM differed by no more than 4 mmHg. In eight mostly uneducated patients (15%, 95% confidence interval, CI, 7-27%) means of reported and real HBPM differed by more than 4 mmHg (range 5-28 mmHg for systolic and 0-11 mmHg for diastolic blood pressure). Systolic agreement between self-reported HBPM and 12-h daytime ABPM was better for patients reporting > or = 80% than for patients reporting < 80% of measurements correctly (mean systolic difference 0 +/- 19 versus 5 +/- 14 mmHg, respectively), whereas the opposite was true concerning agreement of diastolic blood pressure values (mean diastolic difference -6 +/- 10 and -1 +/- 9 mmHg, respectively). CONCLUSION Inadequate conclusions due to poor reporting accuracy of HBPM are possible, especially in less educated patients. Thus, ABPM or automatically stored HBPM may be preferable to self-reported HBPM in these patients.

Abstract
To study the effects of the angiotensin II receptor antagonist Losartan and Amlodipine on left ventricular mass (LVM), we performed blood pressure measurements and transthoracic echocardiographies at baseline. After a 4-week placebo run-in period, 25 patients with mild-to-moderate essential hypertension were randomly allocated to active treatment with Losartan 50 mg titrated to Losartan 50 mg/hydrochlorothiazide (HCT) 12.5 mg (n = 11) or Amlodipine 5 mg titrated to 10 mg (n = 14) for 16 weeks. After treatment, blood pressure decreased significantly in both groups. LVM and LVM index (mean +/- SD/median) in the Losartan group at baseline were 311 +/- 101/288 g and 163 +/- 55/150 g/m(2) and decreased significantly to 252 +/- 25/255 g and 133 +/- 22/128 g/m(2) (p = 0.003 for LVM; p = 0. 01 for LVM index) after 16 weeks of active treatment. In the Amlodipine group LVM and LVM index decreased from 259 +/- 47/243 g and 136 +/- 25/ 131 g/m(2) to 240 +/- 42/234 g and 126 +/- 24/123 g/m(2) (n.s.). In conclusion, LVM decreased significantly as early as 16 weeks after initiation of antihypertensive treatment with the Angiotensin II antagonist Losartan.

Abstract
BACKGROUND Telemedicine is use of the new computer-based communication technologies for medical purposes. It augments the exchange of scientific information, while its applications in the fields of patient care and medical education cover remote diagnosis and therapy as well as remote education and training. METHOD This article reviews the development of telemedicine and its application to specialties such as anaesthesiology, dermatology, medicine, surgery and pathology at the University Hospital of Basle, Switzerland. RESULTS Since 1980 the Department of Medicine has held multidisciplinary teleconferences for expert consultation and medical education. Since 1992 the Institute of Pathology has been linked to remote hospitals for real-time biopsy, and, since 1997, remote dermato-histopathological diagnosis has been performed in conjunction with a number of centres and practitioners. International academic teleconferences have been held in the field of surgery since 1986 and there is an interactive education programme via telemedicine in the field of anaesthesiology. The technology in use must be adapted to needs: since few practitioners are currently connected to the Internet, teleconferencing will still be the rule in the Department of Medicine. Remote diagnosis in dermatology and pathology requires high-resolution images transmitted by self-developed software via 64 Kb/s ISDN connection, while surgery works with ISDN teleconferencing at 384 Kb/s to ensure live transmission of surgical procedures with high-quality images. CONCLUSION Our practice, based on several hundred cases, suggests that telemedicine is useful in simplifying and expanding access to remote interdisciplinary expertise, as well as improving medical education in a number of specialties. Telemedicine's multidisciplinary approach is to be recommended.

Abstract
BACKGROUND Although they have been marketed widely, few data about the diagnostic accuracy of blood pressure monitors are available. METHODS Repeated measurements of blood pressures in 85 patients were performed in random sequence with two oscillometric blood pressure monitors around the upper arm (Visomat OZ2) and the wrist (Omron R3( and with a standard sphygmomanometer. The oscillometric blood pressure monitors were validated according to protocols of the British Hypertension Society (BHS) and the American Association for the Advancement of Medical Instrumentation (AAMI). Subsequently, sensitivity and specificity of these monitors for the diagnosis of hypertension or exclusion of the possibility of its presence in a general medical outpatient population were calculated. RESULTS Sphygmomanometric readings exceeded oscillometric blood pressure measurements by 3.7+/-7.5/4.8+/-5.6 mmHg (systolic/diastolic) for the upper arm and 5.7+/-6.2/6.8+/-6.8 mmHg for the wrist. Deviations occurred in both directions and were higher for blood pressures in the hypertensive range. Oscillometric blood pressure measurements at the upper arm, but not at the wrist, satisfied validation criteria of BHS and AAMI protocols. Optimal sensitivity and specificity for the diagnosis of hypertension, defined as blood pressure > 140/90 mmHg with a standard sphygmomanometer, was achieved with blood pressure limits of 133/82 mmHg for the Visomat OZ and 131/80 mmHg for the Omron R3. CONCLUSIONS Average sphygmomanometer values exceed oscillometrically measured blood pressure values but individual disagreements cannot be predicted. Measurements at the upper arm are more accurate than are those at the wrist according to the validation protocols of the BHS and AAMI. Additional appraisal of sensitivities and specificities and of a 'range of uncertainty' for the diagnosis of hypertension may allow better judgement of accuracy of individual oscillometric blood pressure measurements.

Abstract
Systemic and especially splanchnic arterial vasodilation accompany chronic portal hypertension. Different soluble mediators causing this vasodilation have been proposed, the strongest evidence being for nitric oxide (NO). No data exist if structural vascular changes may partly account for this vasodilatory state. Here, we developed a new in vivo quantitative angiogenesis assay in the abdominal cavity and determined if: 1) portal hypertensive rats show increased angiogenesis; and 2) angiogenesis is altered by inhibiting NO formation. Portal hypertension was induced by partial portal vein ligation (PVL). Sham-operated rats served as controls (CON). During the index operation (day 0), a teflon ring filled with collagen I (Vitrogen 100) was sutured in the mesenteric cavity. After 16 days, rings were explanted, embedded in paraffin, and ingrown vessels counted using a morphometry system. The role of NO was tested by adding an antagonist of NO formation (Nomega-nitro-L-arginine [NNA], 3.3 mg/kg/d) into the drinking water. The mean number of ingrown vessels per implant was significantly higher in PVL rats compared with CON rats, i.e., 1,453 +/- 187 versus 888 +/- 116, respectively (P <.05; N = 5 per group). NNA significantly (P <.01) inhibited angiogenesis in PVL (202 +/- 124; N = 5) and in CON (174 +/- 25; N = 6) rats, respectively. In contrast, the beta-adrenergic blocker, propranolol, did not prevent angiogenesis either in PVL or CON rats in a separate set of experiments (data not shown). The conclusions drawn from this study are that: 1) rats with portal hypertension show increased angiogenesis; and 2) inhibition of NO formation significantly prevents angiogenesis in both PVL and CON rats. Therefore, splanchnic vasodilation in chronic portal hypertension may also be a result of structural changes.

Abstract
Outpatients with essential hypertension were randomized to receive antihypertensive treatment with either mibefradil or enalapril. Ambulatory blood pressure measurement (ABPM) and video capillary microscopy of the finger nailfold were performed at baseline and after 12 weeks of treatment. In the enalapril group (n = 21) baseline ABP was 156 +/- 12/100 +/- 9 mm Hg and decreased to 140 +/- 17/89 +/- 10 mm Hg after 12 weeks. In the mibefradil group (n = 22) mean 24-h ABP decreased from 159 +/- 14/102 +/- 7 to 140 +/- 10/89 +/- 7 mm Hg. Capillary blood cell velocity (CBV) without treatment was 0.90 +/- 0.58 mm/s (mean +/- SD) and 0.83 +/- 0.46 mm/s at rest and 0.30 +/- 0.22 and 0.21 +/- 0.20 mm/s immediately after local finger cooling in the mibefradil and the enalapril group, respectively. In the Enalapril group CBV at week 12 was 0.99 +/- 0. 60 mm/s (n.s.) at rest and 0.40 +/- 0.28 mm/s immediately after local cooling (P = 0.005 compared to 0.21 +/- 0.20 mm/s without treatment). Twelve weeks after initiation of treatment CBV was 0.76 +/- 0.48 mm/s (n.s.) at rest and 0.31 +/- 0.28 mm/s (n.s.) immediately after local cooling in the mibefradil group. Finger nailfold CBV immediately after local finger cooling was increased by enalapril compared to baseline. The T-channel-inhibiting calcium antagonist mibefradil did not change CBV in finger nailfold capillaries.

Abstract
Quality aspects get more important in internal medicine due to novel technical developments and economic constraints. In spite of an extensive research activity in clinical medicine some research aspects of quality control are new. Among these are investigations about symptoms and complaints as well as risk factors. Too much evidence might also blur the view when the necessary data might already be available from existing studies but conclusions have not been drawn to improve quality of patient care. An instrument to this end is metaanalysis compounding the results of single studies to a more meaningful result. Thus further unnecessary trials can be avoided. Finally quality control is characterized by readiness to self-criticism. Its aim is to avoid mistakes and intends to optimize medical actions whenever possible.

Abstract
Lipid-lowering therapy reduces cardiovascular morbidity and mortality. Although atherosclerotic plaques regress under lipid-lowering therapy, only minor changes in arteriosclerotic plaques are angiographically detectable. These changes cannot fully explain all the benefits of lipid-lowering therapy. Additional factors independent of macroscopically detectable alterations in plaque size may contribute to the clinical effects of lipid-lowering therapy. Qualitative changes in the composition of atherosclerotic plaques may reduce the risk of subsequent plaque rupture. Furthermore, hypercholesterolemia is associated with endothelial dysfunction, i.e., impaired endothelium-mediated vasodilation, induction of adhesion molecules, and altered expression of growth factors. Lipid lowering seems to reverse endothelial dysfunction. Also, lipid-lowering therapy may reduce peripheral arterial resistance and hyperinsulinemia, and may improve erythrocyte deformability. These effects of lipid-lowering therapy may contribute to the clinical benefits. In particular, the concept of endothelial dysfunction as a first, reversible manifestation of target organ damage deserves further attention in the diagnosis and therapy of cardiovascular disease.

Abstract
OBJECTIVE To evaluate the accuracy of a preliminary diagnosis based solely on patient history and physical examination in medical outpatients with abdominal or chest pain. DESIGN Prospective observational study. SETTING General medical outpatient clinic in a university teaching hospital. PARTICIPANTS One hundred ninety new, consecutive patients with a mean age of 44 years (SD = 14 years, range 30-58 years) with a main complaint of abdominal or chest pain. MEASUREMENTS AND MAIN RESULTS The preliminary diagnosis, established on the basis of patient history and physical examination, was compared with a final diagnosis, obtained after workup at completion of the chart. A nonorganic cause was established in 66 (59%) of 112 patients with abdominal pain and in 65 (83%) of 78 with chest pain. The preliminary diagnosis of "nonorganic" versus "organic" causes was correct in 79% of patients with abdominal pain and in 88% of patients with chest pain. An "undoubted" preliminary diagnosis predicted a correct assessment in all patients with abdominal pain and in all but one patient with chest pain. Overall, only 4 patients (3%) were initially incorrectly diagnosed as having a nonorganic cause of pain rather than an organic cause. In addition, final nonorganic diagnosis (n = 131) was compared with long-term follow-up by obtaining information from patients and, if necessary, from treating physicians. Follow-up information, obtained for 71% of these patients after a mean of 29 months (range 18-56 months) identified three other patients that had been misdiagnosed as having abdominal pain of nonorganic causes. Compared with follow-up, the diagnostic accuracy for nonorganic abdominal and chest pain at chart completion was 93% and 98%, respectively. CONCLUSIONS A preliminary diagnosis of nonorganic versus organic abdominal or chest pain based on patient history and physical examination proved remarkably reliable. Accuracy was almost complete in patients with an "undoubted" preliminary diagnosis, suggesting that watchful waiting can be recommended in such cases.

Abstract
Treatment of hypertension and hyperlipidaemia improves cardiovascular and overall mortality in patients with coronary heart disease. Adequate awareness of atherogenic risk factors is a key first step that enables patients to address their risk factors. In a recently completed study in coronary heart disease patients at coronary angiography and 18 months later, we found that skewed views about atherogenic risk factors in general were expressed. In addition, awareness of the patients' own hypercholesterolaemia or diabetes mellitus was often inadequate or lacking, in contrast to their awareness of blood pressure or bad smoking habits. Awareness of risk factors had only marginally improved 18 months after the initial investigation. Smoking habits, total cholesterol, and HDL values had improved over 18 months but lipid values were far from reaching target values of accepted guidelines. A majority of our patients remained with at least one treatable and insufficiently controlled atherogenic risk factor, usually hypercholesterolaemia. Interestingly, higher awareness of risk factors correlated with better risk factor control. These observations suggest that systematic interventions are necessary to further ameliorate secondary prevention in coronary heart disease. Successful standardized programmes of high or perhaps medium intensity, that include systematic screening of risk factors, reasoned educational interventions, and methodical management of treatable atherogenic risk factors according to accepted, guidelines, therefore require further attention in daily medical practice.

Abstract
Intraindividual variability of serum lipid concentrations in normal volunteers and in patients with hyperlipidemia is substantial. The aim of this study was to investigate prospectively the reproducibility of fasting serum triglyceride and total cholesterol concentrations in primary health care patients with combined hyperlipidemia, i.e. under conditions of daily medical practice. Secondary forms of hyperlipidemia were excluded. 19 general medical outpatients with primary combined hyperlipidemia were studied. Serum total cholesterol and triglyceride concentrations were measured after an overnight fast at 08.00 h 4 times at weekly intervals. To study the influence of alcohol intake on serum lipid concentrations, total cholesterol and triglycerides were measured without alcohol influence and 12 hours after consumption of a mean of 100 g alcohol in the evening. In 19 patients (10 males, 9 females, mean age 55 years, body mass index 27.9 +/- 4.4 kg/m2), mean +/- SD of serum triglycerides was 3.97 +/- 1.8 mmol/l and of total cholesterol 7.9 +/- 1.8 mmol/l. The combined intraindividual and interassay coefficient of variation was 18.7 +/- 8.2% for triglycerides and 5.1 +/- 2.5% for total cholesterol. Fasting serum triglycerides (3.5 +/- 1.1 vs. 3.7 +/- 1.4 mmol/l) and total cholesterol (7.6 +/- 1.4 vs. 7.8 +/- 1.0 mmol/l) did not significantly change 12 hours after acute alcohol consumption. Patients with primary combined hyperlipidemia in a primary health care setting show small intraindividual variations of overnight fasted serum triglyceride and total cholesterol concentrations. Moderate alcohol consumption 12 hours before blood sampling does not significantly affect triglyceride and cholesterol values.
