ABSTRACT
OBJECTIVES: Vertigo is a common reason for primary care consultations, and its diagnosis and treatment consume considerable medical resources. However, limited information on the specific cost of vertigo is currently available. The aim of this study is to analyse the health care costs of vertigo and examine which individual characteristics would affect these costs. STUDY DESIGN: We used cross-sectional data from the German KORA ("Cooperative Health Research in the Augsburg Region") FF4 study in 2013. METHODS: Impact of personal characteristics and other factors was modelled using a two-part model. Information on health care utilisation was collected by self-report. RESULTS: We included 2277 participants with a mean age of 60.8 (SD = 12.4), 48.4% male. Moderate or severe vertigo was reported by 570 (25.0%) participants. People with vertigo spent 818 Euro more than people without vertigo in the last 12 months (2720.9 Euro to 1902.9 Euro, SD = 4873.3 and 5944.1, respectively). Consultation costs at primary care physicians accounted for the largest increase in total health care costs with 177.2 Euro (p < 0.01). After adjusting for covariates, the presence of vertigo increased both the probability of having any health care costs (OR = 1.6, 95% CI =[1.2;2.4]) and the amount of costs (exp(ß) = 1.3, 95% CI = [1.1;1.5]). The analysis of determinants of vertigo showed that private insurance and a medium level of education decreased the probability of any costs, while higher income increased it. CONCLUSIONS: The presence of vertigo and dizziness required considerable health care resources and created significantly more related costs in different health care sectors for both primary and pertinent secondary care.

PURPOSE: Due to demographic aging, economic evaluation of health care technologies for the elderly becomes more important. A standardised questionnaire to measure the health-related resource utilisation has been designed. The monetary valuation of the resource use documented by the questionnaire is a central step towards the determination of the corresponding costs. The aim of this paper is to provide unit costs for the resources in the questionnaire from a societal perspective. METHODS: The unit costs are calculated pragmatically based on regularly published sources. Thus, an easy update is possible. RESULTS: This paper presents the calculated unit costs for outpatient medical care, inpatient care, informal and formal nursing care and pharmaceuticals from a societal perspective. CONCLUSION: The calculated unit costs can serve as a reference case in health economic evaluations and hence help to increase their comparability.

AIM: Due to demographic trends towards an ageing population resource use of health care will increase. By collecting health-related costs via questionnaires, the impact of socio-economic variables and other medical factors can be examined. In addition, only patient reported resource use accounts for out-of-pocket payments. Thus, it is necessary to develop an appropriate tool to collect the health-related resource use in an elderly population. METHODS: The development of the FIMA (questionnaire for the use of medical and non-medical services in old age) was carried out in 6 steps. These included the determination of necessary questionnaire contents based on a literature review and the wording and layout were defined. Finally the questionnaire was tested in a pilot study and was modified. RESULTS: All direct medical and non-medical resource use excluding transportation and time costs were recorded. Productivity losses were not included. The recall time frames differed according to resource categories (7 days, 3 months, 12 months). For the pilot study, 63 questionnaires were analysed. The response rate was 69%. The questionnaire took an average of 21 min to complete. Three quarters of respondents completed the questionnaire without help and 90% rated the difficulty as easy or even very simple. There was good agreement between self-reported health-related quality of life and the resource use of nursing and domestic help (phi coefficient values between 0.52 and 0.58). CONCLUSION: The FIMA is a generic questionnaire which collects the health-related resource use within the older population groups.

BACKGROUND: Diabetes is frequently diagnosed in patients with cirrhosis and represents an important risk factor for morbidity and mortality. Pharmacological therapy is limited due to hepatotoxicity and the risk of hypoglycemia. Investigations on medical practice in this patient population, frequency of diabetes-associated complications and the impact of quality of metabolic control are rare. AIMS AND METHODS: A retrospective analysis was performed to compare the effects of hypoglycemic treatment, the achieved glycemic control under therapy, the prevalence of typical cirrhosis-related or microangiopathic complications, and cardiovascular comorbidities between a group of diabetic patients with cirrhosis (n = 87) and a nondiabetic cirrhotic population (n = 198). RESULTS: The prevalence of diabetes in our cohort was 30.5%. Of all diabetic patients, 39.1% received therapy which might potentially result in serious side effects in patients with end-stage liver disease. The rate of ongoing alcohol abuse (28.7%) and noncompliance under medication (41.4%) was high. Only 28.7% of all diabetic subjects showed satisfactory (as defined by HbA1c ≤ 6.5%) glycemic control under therapy. Patients achieving satisfactory control experienced a lower rate of certain cirrhosis-related complications such as hepatic encephalopathy (HE) and hepatocellular carcinoma (HCC), arterial hypertension, and hypercholesterolemia. HE was significantly more frequent in diabetic than nondiabetic cirrhotic patients.

BACKGROUND: Although there is profound knowledge about cyclic fasting motility, the postprandial intestinal motor response is not well investigated. It is intriguing to speculate that nutrient composition alters small bowel motility significantly and, in a clinical setting, may account for adverse gastrointestinal symptoms in enteral nutrition (EN). We aimed to assess the impact of different caloric loads and osmolarities of EN on human jejunal motility. METHODS: Sixteen healthy subjects underwent a series of duodenal infusions of EN solutions, either with iso-osmolar solution with different caloric loads (1.32, 2.64, or 3.96 kcal min(-1)), or with solutions of different osmolarities with constant caloric loads (300, 600, or 1200 mosmol). Jejunal solid-state manometry was analyzed over 90 min both visually and using dedicated computer software. KEY RESULTS: All tested nutrient solutions were able to trigger conversion to a postprandial jejunal motility pattern after a mean lag phase of 9.4 + 2.3 min (P = NS between different nutrient solutions). Different caloric loads did not result in significant differences in small bowel motility. However, increasing osmolarities caused a significant inhibition of contractile and propagative activity. CONCLUSIONS & INFERENCES: Small bowel motility under duodenal infusion of nutrient solutions is not influenced by caloric load in a physiological range, whereas high osmolarities inhibit small bowel motility.

INTRODUCTION: Impaction of foreign bodies in the upper gastrointestinal tract represents a rare endoscopic emergency regarding the danger of organic lesions. Therefore, the therapeutic strategy, rational postinterventional monitoring and potential consequences for the course in the future are often not clear. METHODS: Out of all oesophagogastroduodenoscopies performed between 2008 and 2010 (n = 10,830), the endoscopies due to bolus impaction were analysed retrospectively concerning endoscopic findings, course of intervention and causative predisposing factors using descriptive statistics. RESULTS: In the study period, endoscopy was performed in 45 different patients 49 times when foreign body impaction was suspected. In 38 cases (77.6%) a foreign body could be detected by endoscopy, most frequently a meat bolus (65.8%), followed by dental prostheses and tablets. Endoscopic removal could be successfully performed in 97.4%. An operation was necessary in only one patient. A macroscopically unremarkable upper gastrointestinal tract without any predisposing conditions for foreign body impaction could be detected in 33.3%. In one case eosinophilic oesophagitis could be diagnosed histologically. The foreign body was pushed into the stomach by the "push technique" in 54.1%. The foreign body removal was performed as an ambulant intervention in 63.2%. DISCUSSION: In the majority of cases, impacted foreign bodies of the upper gastrointestinal tract could be removed safely by endoscopy, e.g., using the "push technique". However, the therapeutic strategy should be individually adjusted based on the consistancy of the foreign body. If no predisposing conditions can be found, histological diagnosis should be performed to detect potential eosinophilic oesophagitis early enough.

INTRODUCTION: Studies analysing the frequency of rhythm disorders in patients with cirrhosis are rare. Nevertheless, factors triggering rhythm disorders occur frequently in cirrhosis. Therefore, a retrospective case control study was performed investigating the frequency of cardiac arrhythmia in a population of patients with cirrhosis while evaluating several associated factors. METHODS: The files of patients with cirrhosis (n â=â 293) in the period 2004 - 2008 were analysed retrospectively regarding cardiac arrhythmia. The frequency of cardiac arrhythmia in the presence of relevant risk factors was analysed using χ ²tests and logistic regression models. RESULTS: 61.1â % of all patients were male (mean age 61.7 years) and 38.9 â% female (mean age 62.8 years). The severity of cirrhosis according to the Child-Pugh score (CP) was as follows: CP A 43.3 â%, CP B 32.8â % and CP C 23.9â %. Altogether, rhythm disorders were diagnosed in 16.4â % (48/293) of the study population, most frequently atrial fibrillation (68.8 â%) and atrial flutter (6.7 â%). An advanced age and comorbidities such as arteriosclerotic diseases, hypercholesterinemia (pâ <â 0.001, each) and diabetes mellitus (p â=â 0.013) correlated significantly with the frequency of rhythm disorders which occurred more often in males than in females (pâ = 0.066). Ongoing alcohol abuse, the severity of cirrhosis and arterial hypertension were not associated significantly with the onset of rhythm disorders. 84.4â % of all patients with cardiac arrhythmia were treated by diuretics. Decreased (< â3.5âmmol/L) and elevated (> â5âmmol/L) potassium values were observed in 60.6 â% of the study collective. Rhythm disorders were more often observed in patients with hyperkalemia (especially atrioventricular block, p â< 0.01). CONCLUSION: Compared to the average population, the prevalence of atrial fibrillation was increased in our cirrhotic cohort. The occurrence of rhythm disorders was significantly associated with arteriosclerotic diseases, hypercholesterinaemia and diabetes mellitus. Additionally, cardiac arrhythmia must be considered under diuretic therapy and in the presence of electrolyte disturbances.

BACKGROUND/AIM: Patients with fecal incontinence (FI) have lower anal resting (MRP) and squeeze (MSP) pressure and an impaired sensitivity compared to healthy people. However, whether anorectal manometry (ARM) can separate precisely between health and disease is discussed controversially. The aim was to evaluate the accuracy of ARM in a huge cohort of patients and controls. METHODS: ARM was obtained in 144 controls and in 559 FI patients. MRP, MSP, and balloon volume at first perception (BVP) and urge sensation (BVU) were determined. Receiver operating curve analysis was used to determine optimal cut-offs and sensitivity, specificity and accuracy calculated. RESULTS: FI patients showed lower MRP, MSP, BVU (p < 0.001) and a higher BVP (p = 0.007). Deterioration of the ARM parameter increased with FI severity. ARM demonstrated an excellent sensitivity (91.4%) and accuracy (85.8%), but only a moderate specificity (62.5%). The sensitivity of ARM rose with FI severity. The pressure data showed higher sensitivity and accuracy than the sensory data despite comparable specificity. CONCLUSIONS: Sensitivity and accuracy of single ARM parameters is only moderate for the pressure data and poor for the sensory data. In contrast, ARM demonstrated an excellent sensitivity, a moderate specificity, and a convincing accuracy justifying its use in clinical routine.

BACKGROUND: Knowledge about human cyclic fasting motility (MMC) and the postprandial response is mostly based on manometric findings in the upper small intestine. Hardly any data exist on human ileal motility, as the acquisition of data has been limited by methodological concerns. The aim was to study human jejunal and ileal motility in an optimized manometric setting. METHODS: Solid-state 24-h-manometry was performed in the jejunum and ileum of healthy individuals, applying a strict protocol for fasting, resting, and the consumption of a standardized meal. Both visual qualitative and validated computerized quantitative contraction and propagation analysis were performed. KEY RESULTS: MMC occurs in similar frequency in the jejunum and ileum, but it was significantly shorter in the jejunum at night. By many characteristics, ileal motility was less intense and propagative than jejunal: less migrating clustered contractions, and slower propagation velocity and shorter distance in phases II and III, and postprandially - possibly slowing and enhancing nutrient absorption. Prolonged propagated contractions in some individuals were identified as a unique ileal propulsive pattern. Postprandially, an abrupt conversion to a digestive motility pattern occurs simultaneously independent of the region. CONCLUSIONS & INFERENCES: We found similar basic phenomena of fasting and postprandial motility in the jejunum and ileum of healthy humans. However, different calibration of propagative and contractile activity and special motor events in the ileum may account for a different physiological role in digestion. Future studies of small-bowel motility in healthy and diseased subjects focusing on segmental differences of proximal and distal intestine may be rewarded.

BACKGROUND: Alcoholic beverages are known to increase acidic gastro-esophageal reflux (GER) and the risk of esophagitis. Moreover, duodenogastro-esophageal reflux (DGER), containing bile acids, was shown to harmfully alter the esophageal mucosa, alone and synergistically with HCl and pepsin. However, studies directly addressing potential effects of different low proof alcoholic beverages on DGER in health and disease are missing. METHODS: Bilitec readings for beer and white, rose, and red wine were obtained in vitro from pure and from mixtures with bile. One-hour DGER monitoring and pH-metry were performed in 12 healthy subjects and nine reflux patients with DGER after ingestion of a standardized liquid meal together with 300 mL of water, white wine, and in the volunteers, beer and rose wine. KEY RESULTS: Bilitec measurement was found to be feasible in the presence of beer, white wine, and using a threshold of 0.25, rose wine. However, the presence of red wine resulted in extinction values above this threshold. The consumption of all investigated alcoholic beverages, especially of white wine, triggered increased acidic GER, both in healthy participants and patients with reflux disease. In contrast, no relevant DGER was found after intake of alcoholic beverages. CONCLUSIONS & INFERENCES: Fiber-optic bilirubin monitoring can be used for DGER monitoring in combination with alcoholic beverages, except with red wine. Low-proof alcoholic beverages are a strong trigger of GER, but not of DGER, both in healthy subjects and patients with reflux disease.

BACKGROUND: The objective of the KORA-Age research consortium is to assess the determinants and consequences of multimorbidity in the elderly and to look into reasons for successful aging in the general public. PATIENTS AND METHODS: In the KORA-Age cohort study 9,197 persons were included who where born in the year 1943 or before and participants of previous KORA cohort studies conducted between 1984 and 2001 (KORA: Cooperative Health Research in the Region of Augsburg). The randomized intervention study KORINNA (Coronary infarct follow-up treatment in the elderly) tested a nurse-based case management program with 338 patients with myocardial infarct and included an evaluation in health economics. RESULTS: A total of 2,734 deaths were registered, 4,565 participants submitted a postal health status questionnaire and 4,127 participants were interviewed by telephone (response 76.2% and 68.9% respectively). A gender and age-stratified random sample of the cohort consisting of 1,079 persons took part in a physical examination (response 53.8%). CONCLUSION: The KORA-Age consortium was able to collect data in a large population-based sample and is contributing to the understanding of multimorbidity and successful aging.

Mesenteric, inflammatory veno-occlusive disease is an entity of unknown incidence and aetiology. Inflammation and necrosis of mesenteric veins leads to severe ischaemic damage of an intestinal segment. The clinical and endoscopic presentation can be ambiguous. However, modern multiphasic contrast-enhanced computed tomography allows early diagnosis, when characteristic features are considered. As local resection is the only known cure with minimal risk of recurrent disease, knowledge of this rare disease entity can spare our patients a risky delay of resection and erroneous therapeutic approaches.

INTRODUCTION: In the literature, data on the effects of gender and age on the pressure data of anorectal manometry differ. Possible reasons are investigation of only small numbers of healthy people and comparison of only 2 groups with large age differences. In addition, data about the influence of gender or age on anorectal sensation are sparse. Therefore, the aim of the present study was to determine the influence of gender and age on anorectal manometry in a large healthy female and male cohort spanning a great age range. METHODS: Anorectal manometry was performed in 72 women and 74 men with a median age of 64 years in both groups (ranges: women 22-90 years; men 23-88 years). We determined mean anal resting and squeeze pressure as well as minimal rectal balloon volume for perception and for urge/desire to defecate. The Mann-Whitney U test was used to analyze for gender differences, regression analysis to search for age influences. RESULTS: Squeeze pressure (p = 0.007) and perception threshold (p < 0.001) are significantly lower in females, while the mean resting pressure and urge threshold are similar in females and males. Mean resting pressure (women p < 0.0001; men p = 0.03) and mean squeeze pressure decrease (women p < 0.0001; men p = 0.004) with age. An age-related increase in sensory thresholds (= decreased rectal sensitivity) is only seen in females (perception threshold p = 0.01; urge threshold p = 0.04). CONCLUSION: Most of the parameters measured by anorectal manometry (anal canal pressure, sensory thresholds) are influenced by gender and age. Therefore, the results of anorectal manometry must be interpreted in relation to sex- and age-adapted normal values.

Uip to 20% of patients with liver cirrhosis develop hepatogenous diabetesdue to the hepatocellular functional loss and insulin resistance. Optimizing diabetic metabolic conditions is not only important to avoid typical late complications of diabetes, but also cirrhosis-associated complications e.g. gastrointestinal bleeding, hepatic encephalopathy or the occurence of hepatocellular carcinoma. So far there have beenno recommendations orguidelines for the diagnosis and treatmentof hepatogenous diabetes. The medical teatment of a diabetic condition is mainly influenced by its side effects. The risk of hypoglycemia must be considered carefully during drug treatment, especially in patients with chronic alcohol abuse. Suitable oral antidiabetics are glinides and short-acting sulfonylureas or possibly meal-related insulin administration with short-acting insulins or rapid-acting insulin analogues. Biguanide and PPAR-gamma agonists are contraindicated because of side effects in liver cirrhosis. Regarding basic treatment, an adequate daily energy and protein supply should be ensuredbecause the majority of patients with liver cirrhosis are malnourished.

Medical treatment of patients with liver cirrhosis consists mainly of symptomatic therapy of associated complications. Apart from the classical complications of cirrhosis, e. g. ascites, portal hypertension or hepatic encephalopathy, other frequent complications are neglected in everyday medicine. The incidence of metabolic disturbances seems to be similar to the prevalence of classical complications of liver cirrhosis, such as portal hypertension or ascites. Osteoporosis is an important manifestation of hepatic osteopathy, especially in chronic cholestatic diseases and in candidates for liver transplantation, which necessitates timely adequate diagnostic test (e. g. osteodensitometry) and treatment (pre-emptive and causal). Malnutrition, especially when related to protein- and energy supply, is very common in patients with liver cirrhosis and has prognostic significance regarding mortality and complication rates. A sufficient daily energy and protein supply should be ensured, one which is higher than that for the normal population. Additional substitution of vitamins and trace elements is indicated when symptoms of deficiency became apparent.

In functional constipation, three pathophysiological subgroups have been identified: slow-transit constipation (STC); normal-transit constipation (NTC) and outlet delay (OD). Extracolonic manifestations, especially disturbed small bowel motility, are well known to occur in STC, but have rarely been studied in NTC and OD. To perform 24-h-ambulatory jejunal manometry in a large prospective series of clinical patients with chronic constipation of all subtypes. A total of 61 consecutive patients, referred to our tertiary gastroenterologic centre for chronic constipation (48 female, 13 male; mean age 57 (range 20-87) years), underwent jejunal 24-h-ambulatory manometry (standardized meal) after a transit-time study (radio-opaque markers), anorectal manometry, defecography and colonoscopy. Computerized and visual analysis by two independent observers was compared with the normal range of manometric variables, defined by data previously obtained in 50 healthy subjects (Gut 1996;38:859). Five patients were excluded from the study because of coexistence of OD and STC. No patient with OD (n = 8), but all patients with STC (n = 32) and 94% of patients with NTC (n = 16) showed small bowel motor abnormalities; both in postprandial response and fasting motility. The abnormal findings ranged from severe disturbances with complete loss of MMC to subtle changes of contraction parameters that could only be assessed by computerized analysis. No significant differences between STC- and NTC-patients were found. Most findings pointed to an underlying enteric neuropathy. Intestinal prolonged-ambulatory manometry adds valuable information to the pathophysiologic understanding of functional chronic constipation of STC- and NTC-type, however there are no distinct manometric features to differentiate between both.

The term chronic intestinal pseudo-obstruction describes a syndrome of severly altered gastrointestinal motility that clinically resembles mechanical intestinal obstruction. The syndrome comprises numerous underlying primary or secondary neuropathies of the intrinsic or entrinsic nervous system as well myopathies. Almost a third of the patients requires long-term total parenteral nutrition (TPN). However, emergency surgery and even small bowel transplantation as an ultimate option after failure of TPN may become necessary to evade a vital threat. Although our understanding of pathogenesis and therapeutical options is still evolving, current knowledge allows a differentiated diagnostic approach, classification of the primary and secondary causes and differentiated therapy.
