[Medical care of patients with spasticity following stroke : Evaluation of the treatment situation in Germany with focus on the use of botulinum toxin]. / Versorgung von Patienten mit Spastik nach Schlaganfall : Evaluation der Versorgungssituation in Deutschland mit dem Fokus auf den Einsatz von Botulinumtoxin.

BACKGROUND: Upper limb spasticity is a common complication following stroke. Cohort studies found 19% of post-stroke patients had upper limb spasticity at 3 months and 38% of patients at 12 months. For focal spasticity, intramuscular injections of botulinum toxin are indicated. In Germany, it is assumed that patients with the described indication are undersupplied with botulinum toxin. OBJECTIVE: The aim of the present study is to evaluate the medical care of patients with upper limb spasticity post-stroke with the focus on the use of botulinum toxin as one treatment option. METHODS: A standardized questionnaire was developed and a postal survey of a representative national random sample of 800 neurologists to capture the actual medical care situation. RESULTS: The response rate amounted to 37% (n = 292). 59% of the neurologists surveyed had never used botulinum toxin. In total, 87% of neurologists noticed barriers regarding the use of botulinum toxin, where the amount of the doctor's remuneration in 40% and the lack of reimbursement of costs in off-label use in 60% were the most commonly used answers. The achievement of an advanced training in using botulinum toxin was also stated as a general obstacle for resident neurologists. DISCUSSION: Due to a response rate of 37% for the postal survey a selection bias cannot be excluded. Although botulinum toxin is recommended in the national treatment guidelines, many neurologists do not use botulinum toxin. The reasons can be seen from the barriers described.

[Secondary data analysis of the prevalence of alcohol dependence (F10.2) in Germany]. / Sekundärdatenanalyse der Prävalenz der Alkoholabhängigkeit (F10.2) in Deutschland.

BACKGROUND AND AIM: Compared to other European countries, alcohol consumption and abuse in Germany is on a high level. Even in smaller quantities, frequent alcohol consumption can generate organic damages and thus lead to secondary diseases that have a significant societal relevance regarding direct and indirect costs for the healthcare system. After several publications have already addressed the prevalence of acute alcohol intoxication and alcohol abuse in adolescents, the question arises how the prevalence of alcohol abuse develops on the basis of the accounting data of outpatient and inpatient care providers in the population of adults aged 18 and over and what tendency can be observed within a multi-year period. Within this study, the coding of alcohol abuse (F10.2 diagnosis) was analyzed separately for outpatient and inpatient sector in the insured population ≥ 18 years and presented over time. PATIENTS AND METHODS: The development of the prevalence of alcohol abuse was analyzed on the basis of secondary random sample data from one nation-wide working statutory health insurance with a total population of more than 3 million insurants in the 5-year period from 2006 to 2010. For the presentation of the prevalences, insurant numbers were used. For the identification of the relevant insurants, only confirmed outpatient F10.2 diagnoses or inpatient F10.2 diagnoses were used. The age and sex distributions of the dataset were adjusted to the distribution in the statutory health insurance to ensure representativeness. The analyses of each single year only allude to insured persons aged ≥ 18 years. With the help of the statistics of the insured of statutory health insurance, for each calendar year, projections of the detected prevalence rates were determined to estimate the number of cases on the statutory health insurance level and their development over time. RESULTS: The results show a tendency of slightly increasing prevalence of alcohol dependence from 2006 to 2010. For insured persons with at least one inpatient or outpatient F10.2 diagnosis, the prevalence continuously rises from 1,04% in 2006 to 1.14% in 2010; the prevalence of insured persons who received an alcohol dependence diagnosis only in the outpatient sector, increased from 0,67% to 0,79% in that time scale. In all analyzes, there was a ratio of 30% affected women to 70% affected men. From 2006 to 2010, the proportion of insured persons with hospitalization caused by alcohol dependence decreased steadily from 14,51% to 12,24%. CONCLUSION: For the analyzed group of persons aged ≥ 18 years, the present analysis results show a tendency of slightly increasing prevalences of alcohol abuse, however at the same time combined with a decreasing proportion of hospitalized patients. Similar nationwide studies from 2010 on the basis of secondary data of a health insurance company and inclusion of outpatient and inpatient diagnoses also indicate prevalences of alcohol dependence of about 1.18%, but they base on the age range of 15- to 64-year-old insurants.

The prevalence of inflammatory sacroiliitis assessed on magnetic resonance imaging of inflammatory bowel disease: a retrospective study performed on 186 patients.

BACKGROUND: Magnetic resonance imaging (MRI) colonography or enterography is increasingly used to assess disease activity and complications in inflammatory bowel disease (IBD). However, no study has evaluated the role of this imaging technique to assess sacroiliitis. AIM: The primary objective was to assess the prevalence of inflammatory sacroiliitis on MRI performed for IBD investigation. The secondary aim was to elucidate clinico-biological factors associated with the presence of sacroiliitis. METHODS: This study was performed on 186 patients suffering from IBD followed in a gastroenterology department between 2004 and 2011: 131 with Crohn's disease and 55 with ulcerative colitis. Clinico-biological and endoscopic data were collected and MR enterography or colonography was performed to assess IBD activity on axial and coronal fat suppressed injected T1-weighted sequences. On MRI, sacroiliitis was scored blindly by two independent readers according to ASAS (Assessment of SpondyloArthritis international Society) criteria. RESULTS: The prevalence of inflammatory sacroiliitis was 16.7% (n = 31). Sacroiliitis was bilateral in 14 cases and unilateral in 17 cases. The sacroiliac joints were considered normal in 144 cases and doubtful in 11 cases. Older age and female gender were significantly associated with the presence of sacroiliitis. Other factors such as type of IBD, disease duration and localisation of IBD, surgery history, biological inflammation, bowel disease activity and treatment were not associated with sacroiliitis. CONCLUSION: Inflammatory sacroiliitis was evidenced by MRI in 16.7% in patients suffering from IBD. Added to clinico-biological data, MRI analysis should contribute to an earlier diagnosis of axial spondylarthritis in patients with IBD.

[The health-care situation in outpatient psychiatry--results of a survey among members of the Germany Association of Psychotherapists (DPtV)]. / Zur Versorgungslage im Bereich der ambulanten Psychotherapie--Ergebnisse einer Erhebung unter den Mitgliedern der Deutschen Psychotherapeuten Vereinigung (DPtV).

BACKGROUND: Mental-health problems are of increasing importance in the German population. Nonetheless there is a lack of data concerning outpatient psychotherapeutic care, especially with a focus on psychotherapy sessions approved by social health insurances and performed by psychological psychotherapists and paediatric psychotherapists. METHODS: The study presents the results of a survey among all members of the German Association of Psychotherapists (DPtV) and is based on questionnaires filled in by 2,497 psychotherapists (return rate 33.3%). The assessment is based on the therapists' data without an external validation. Main topics of the survey were characteristics of the supply of psychotherapeutic care, therapeutic time contingents per patient and their utilisation and demographic and socio-economic features of patients. Evaluating the survey, the results were analysed overall and by groups of therapists varying in demographic features, professional qualifications and regional criteria, using bivariate as well as multivariate methods. RESULTS: The study provides evidence indicating an underprovision of outpatient psychotherapeutic care. Psychotherapists who use a waiting list reported average waiting times of more than 2.5 months. Additionally there are differences in psychotherapeutic care between various patient groups. In regions with lower population density we found less provision of psychotherapeutic care compared to regions with higher population density. Taking into account epidemiological data, the study indicates that the participation of men, persons of older age and patients with lower levels of education in psychotherapeutic care is below average. CONCLUSION: The results suggest a considerable degree of underprovision and inadequate provision of outpatient psychotherapeutic care. With regard to special population groups, further research is necessary to identify utilisation barriers towards psychotherapy.

[Cancer prevention with the endoscope. Search not only for polyps!]. / Krebsvorsorge mit dem Endoskop. Fahnden Sie nicht nur nach Polypen!

Through the rigorous application of polypectomy, the colon carcinoma rate can be clearly reduced (66%). The term "polyp" comprises epithelial (hyperplastic or neoplastic) and nonepithelial causes. The majority of carcinomas in the colon develop from adenomatous tissue (adenoma-carcinoma sequence). Pedunculated adenomas (90% of all polyps) are removed with the high-frequency diathermy snare. In some cases, flat (sessile) polyps can be elevated by injections placed below them, and then removed with the diathermy snare (strip biopsy). In the event of larger or large-area flat polyps that cannot be removed with the snare, piecemeal resection is applied. The excision alone of adenomas with a stage I carcinoma is carried out only in so-called low-risk situations. Flat neoplasms make particular demands of the endoscopist, since they often appear merely as a reddish area, but may already have invaded the submucosa when diagnosed. For classification and, where indicated, endoscopic resection, the recommendations of the Japanese Society of Gastroenterological Endoscopy are applied.

[Nutritional therapy in gastrointestinal diseases. Diets--necessary or superfluous?]. / Ernährungstherapie bei Magen-Darm-Erkrankungen. Diäten--nützlich oder überflüssig?

Diets form a part of the treatment concept in numerous gastrointestinal diseases. Their effectiveness, however, varies considerably from one disease to another. Thus, for example, diet is of decisive importance in celiac disease and lactose intolerance. In contrast, dietary measures are ineffective in the treatment of gallstones, and uncertain as a prophylactic measure against biliary colic. While dietetic measures are an important temporary measure in acute pancreatitis, in chronic pancreatitis such an approach is often not complied with, since it includes abstinence from alcohol. In chronic inflammatory bowel disease, diet can ameliorate a number of complications, although it leaves the pathological process itself unaffected. High-fiber diet is, for the most part, ineffective in patients with irritable bowel syndrome. The present article discusses the benefits of dietary measures in a number of gastroenterological disorders.

[Improving prognosis of chronic liver diseases with specific nutrition]. / Chronische Lebererkrankungen Prognose verbessern mit gezielter Ernährung.

A sensible diet is capable of reducing the complications of chronic liver disease and improving the patient's prognosis. In patients with compensated liver disease, adequate nutrition should be ensured, but specific therapeutic measures are not generally required. Patients with decompensated liver disease often have deficient nutrition or malnutrition. In these patients specific dietary measures make good sense.

Bile and acid reflux in long and short segment Barrett's esophagus, and in reflux disease.

Gastroesophageal acid reflux (GER) is the primary risk factor for gastroesophageal reflux disease (GERD). In long segment Barrett's esophagus (LSBE) duodenogastroesophageal reflux (DGER) parallels acid reflux. The role of GER and DGER in short segment Barrett's esophagus (SSBE) remains to be determined. The aim of the present prospective study was to investigate the esophageal bile and acid reflux in patients with LSBE, SSBE and patients with GERD. Three groups of patients were studied: Patients with LSBE (n = 12), SSBE (n = 20) and patients with GERD without intestinal metaplasia (n = 33). Subjects underwent esophageal manometry and simultaneous 24-h pH and bile monitoring (Bilitec 2000). The thresholds for GER and DGER were a deMeester score > 14.7 and an absorbance value > 0.2 for 10.9% of total period, respectively. GER did not differ between the groups (p > 0.05). However, DGER differed between patients with LSBE, SSBE and GERD (14.7 vs 2.1 vs 2.1, respectively; p < 0.05). H. pylori status did not influence GER and DGER significantly. In contrast to patients with LSBE the DGER does not seem to play an important role in patients with SSBE and patients with GERD. This result indicates a different etiopathology of both long and short segment Barrett's esophagus.

[Peptic ulcer in the elderly--endoscopy in suspected ulcer. Therapy always includes proton pump inhibitor]. / Peptisches Ulkus im Alter--bei Verdacht endoskopieren. Zur Therapie gehören in jedem Fall Protonenpumpenhemmer.

In the elderly patient, peptic ulcer disease is associated with increased morbidity and mortality. Abdominal pain is often absent, and the first sign is blood in the stools. The major risk factors are infection with Helicobacter pylori and the use of non-steroidal antiinflammatory drugs (NSAIDs). Endoscopic and medical treatment of peptic ulcer is independent of the age. The use of proton pump inhibitors is the treatment of choice. In the event of an infection with H. pylori, eradication treatment is usually carried out. Currently, however, H. pylori eradication is not recommended in patients with NSAID-associated ulcers; if possible, the NSAIDs should be discontinued. The development of a new generation of NSAIDs holds out the promise of a marked reduction in gastrointestinal side effects.

L-Glutamic acid and L-lysine as useful building blocks for the preparation of bifunctional DTPA-like ligands.

Bisalkylation of suitably protected L-glutamic acid and L-lysine derivatives with tert-butyl N-(2-bromoethyl)iminodiacetate 2, followed by deprotection of the omega functional group affords N, N-bis[2-[bis[2-(1, 1-dimethylethoxy)-2-oxoethyl]amino]ethyl]-L-glutamic acid 1-(1, 1-dimethylethyl) ester 4 and N2,N2-bis[2-[bis[2-(1, 1-dimethylethoxy)-2-oxoethyl]amino]ethyl]-L-lysine 1,1-dimethylethyl ester 7. Such compounds feature a carboxylic or an amino group, respectively, which are available for conjugation with a suitable partner via formation of an amide bond. The conjugates, which can be prepared in this way, contain a chelating subunit in which all five acetic residues of DTPA are available for the complexation of metal ions. Direct bisalkylation of glycine with 2 promptly gives N, N-bis[2-[bis[2-(1,1-dimethylethoxy)-2-oxoethyl]amino]ethyl]glycine 11. The latter allows to achieve conjugates in which the central acetic group of DTPA is selectively converted into an acetamide.

[Endosonography controlled transgastric drainage of pancreatic pseudocysts]. / Endosonographisch geführte transgastrale Drainage von Pankreaspseudozysten.

BACKGROUND AND OBJECTIVE: Endoscopic drainage of a pancreatic pseudocyst is an alternative to surgical intervention. But transmural drainage carries the risk of bleeding or perforation. Effectiveness and complication rate of endoscopic ultrasound-guided drainage, to avoid these risks, was investigated. PATIENTS AND METHODS: Eleven patients (eight men, three women; mean age 55 years) with a pancreatic pseudocyst (nine with alcoholic and two with biliary pancreatitis) were studied prospectively between 1996 and 1998. In all of them transpapillary drainage of the cyst had not been technically possible. After an endoscopic ultrasound (EUS) examination, the gastric wall was incised with a fistulotome under EUS guidance. A guide-wire was then advanced through the fistulotome into the pseudocyst. A double pigtail catheter was implanted for drainage. The size of the pseudocyst was monitored sonographically at two-week intervals. RESULTS: A cystogastrostomy was successfully established in ten of the twelve patients without serious complication. The pseudocyst was no longer demonstrated after a mean of 4.2 months (2 weeks to 6 months), while a small pseudocyst (1.6 cm [0.9-2.4 cm) remained in three patients. In two of the latter the size of the pseudocyst increased again after removal of the drainage catheter. Complete drainage by repeat cystogastrostomy succeeded in one of them, while a cystojejunostomy was established in the other. CONCLUSION: Endoscopic ultrasound-guided transgastric drainage of a pancreatic pseudocyst is an effective treatment with few complications.

[The value of electrogastrography for the diagnosis of gastroenterologic function]. / Stellenwert der Elektrogastrographie in der gastroenterologischen Funktionsdiagnostik.

BACKGROUND AND OBJECTIVE: Abnormalities of gastric myoelectric activity can be measured by electrogastrography (EGG). Such dysfunctions can be associated with disorders of gastric motility. It was the aim of this study to investigate the relationship between gastric electrical activity and motility in patients with dyspepsia due to gastrointestinal or extraintestinal disease. PATIENTS AND METHODS: 135 consecutive patients with dyspepsia (standardized score) were enrolled in this prospective study including patients with functional dyspepsia (FD) (n = 25), dyspepsia in diabetes mellitus type II (n = 27), hyperthyroidism (n = 23), progressive systemic scleroderma (PSS) (n = 20), chronic alcoholism (n = 20), and 20 patients with gastric lesions: gastric ulcer (n = 10) or gastric cancer (n = 10). The EGG measurements were performed over 60 min pre- and post-prandially state after ingestion of a solid-liquid test meal (370 kcal). The following parameters were measured: dominant electrical frequency (DF), percentage of DF in the normal frequency range (2-4 cpm), bradygastria (< 2 cpm), tachygastria (4-10 cpm), dominant frequency instability coefficient (DFIC), and power ratio. The data were compared with results in 40 healthy persons. The gastric emptying was determined by the gastric retention of 99mTc colloid after 60 min (gamma camera). RESULTS: Nearly 50% of FD patients had delayed gastric emptying (gastric retention after 60 min > 68%): they patients exhibited significantly more tachygastrias than those with normal gastric emptying (P < 0.05). Patients with diabetes mellitus type II, PSS and chronic alcoholism showed normal electrical activity, although gastric emptying was delayed in nearly 50%. The hyperthyroid patients had increased tachygastria without abnormal gastric motility. Gastric lesions did not produce pathological electrogastrograms. The dyspepsia score did not correlate with either EGG or radioscintigraphy in the various patient groups. CONCLUSIONS: Electrogastrography can detect tachygastrias, which are significantly increased in some patients with functional dyspepsia. Because of therapeutic consequences electrogastrography seems to be indicated in patients with functional dyspepsia.

[Diverticulosis and diverticulitis in the elderly]. / Divertikulose und Divertikulitis beim alten Menschen.

Diverticulosis of the colon is a disease that mainly affects the elderly, presenting in 10 to 20% of this age group. The most common complication--painful diverticular disease, is usually treated conservatively with a high-fiber diet, intermittent use of antispasmodics and possibly regulation of the stools. Diagnostic differentiation is best performed using ultrasonography of the bowel wall, supplemented where necessary by computer tomography and colonoscopy (sigmoidoscopy) or, where this latter is not possible, barium enema using Gastrografin. Conservative treatment of diverticulitis with antibiotics, bowel rest, possibly including parenteral alimentation, is usually applied for three to ten days. In the absence of a response to this treatment, frequent recurrence, immunosuppression or complications (perforation, peritonitis, enterovesicular fistula), surgery is indicated.

Dissolution of gallbladder stones with methyl tert-butyl ether and stone recurrence: a European survey.

Since there are now several ways to treat symptomatic gallstone disease, one is able to select treatment on the basis of the patient's comfort, the practicability, effectiveness, and side effects of the technique, and the relative costs. In order to assess the present status of contact dissolution with methyl tert-butyl ether with regard to these aspects, the present enquiry reports the data of 21 European hospitals. Eight hundred three patients were selected for contact litholysis of cholesterol gallbladder stones using methyl tert-butyl ether. Percutaneous transhepatic puncture of the gallbladder was performed under x-ray or ultrasound guidance. Dissolution rate, side effects, and treatment times of 268 patients from one single center were compared to those of 535 patients from the other 20 centers. Two hundred sixty-four patients were followed for five years to assess stone recurrence. Physicians were asked how they assessed the expenditure of the method, the discomfort to the patients, and the staffing situation. Patients were asked to indicate their acceptance on an analog scale. Puncture was successful in 761 (94.8%) patients. Prophylactic administration of antibiotics was not necessary. Stones were dissolved in 724 (95.1%) patients. In 315 (43.5%) sludge remained in the gallbladder. The most severe complication was bile leakage, which led 12 (1.6%) patients to have elective cholecystectomy. Toxic injuries due to the ether were not reported. Method-related lethality amounted to 0%, 30-day-lethality to 0.4%. Stone recurrence rate was about 40% in solitary stones and about 70% in multiple stones over five years. Patients with multiple stones developed recurrent stones almost twice as often as those with solitary stones. The probability of stone recurrence in patients with sludge in the gallbladder after catheter removal was not statistically significantly different from those without sludge. Seventy to 90% of the centers found the puncture to be simple and not distressing for patients and the relation between expenditure and therapeutic success to be acceptable. The acceptance of contact litholysis by the patients was excellent. Contact litholysis when applied by an experienced team provides real advantages in the treatment of gallstone disease. The method is technically simple, well accepted by the patients, and can be easily applied in community hospitals. Contact litholysis may be of particular value in patients who are not suitable for anesthesia or surgery.

Treatment of bleeding esophageal varices with cyanoacrylate and polidocanol, or polidocanol alone: results of a prospective study in an unselected group of patients with cirrhosis of the liver.

BACKGROUND AND STUDY AIMS: Data concerning the results with emergency and further elective therapy of esophageal varices using polidocanol and cyanoacrylate, or polidecanol alone, in an unselected group of patients with liver cirrhosis have not previously been available. The aim of the present prospective study was to evaluate acute and repeated cyanoacrylate and polidocanol therapy in the emergency and long-term elective management of esophageal varices. METHODS: In accordance with the protocol of the present prospective study, acutely bleeding esophageal varices of grades 1 to 3 were treated endoscopically with polidocanol injection, while grade 4 varices, large solitary varices (over 5 mm) and otherwise uncontrollable cases of variceal bleeding were treated by injection of cyanoacrylate and polidocanol. Over a period of 62 months, 112 patients (65 men, 47 women) with acute bleeding from esophageal varices due to cirrhosis of the liver (69% alcohol-related) underwent a total of 245 treatment sessions in hospital. The average age of the patients was 62.0 +/- 12.3 years (58.1% were 60 or older). Hepatic function corresponded to Child-Pugh class A in 38 patients (33.9%), Child-Pugh class B in 68 patients (60.7%), and Child-Pugh class C in six (4.5%). RESULTS: Sixty-eight patients (60.7%) were treated with polidocanol alone, and 44 (39.3%) with cyanoacrylate and polidocanol. Acute hemostasis was achieved in all cases. In 5.7% of the sclerotherapy procedures, bleeding ulcers were observed, and a pleural effusion was seen in one case. The hospital mortality rate was 24.1%, resulting from the bleeding in 2.7% and due to liver failure in the remaining cases. Recurrent bleeding occurred within 24 hours in four patients (3.6%), and during the later course of the hospital stay in a further 11 patients (9.8%). The mean survival time was 13.7 +/- 17.7 months. Over the entire observation period of 23 +/- 21 months, 67 patients died (59.8%); the cause of death was hemorrhage in 4.5%, the underlying hepatic disease in 65.7%, and non-hepatic causes in 29.8%. Recurrent bleeding occurred in 58 patients (51.7%). The cumulative survival rate in the patients treated with cyanoacrylate and polidocanol was 66 +/- 15% and 26 +/- 32% after one and five years, respectively, and 56 +/- 13% and 33 +/- 19% in those treated with polidocanol alone. CONCLUSIONS: Endoscopic treatment of esophageal varices with cyanoacrylate and polidocanol, or polidocanol alone, is effective in controlling bleeding, and the complication rate is tolerable. The short-term and long-term mortality rates are determined largely by the underlying liver disease.
