Aktuelle Epidemiologie der Tuberkulose weltweit,in Europa und in Deutschland

Background

Tuberculosis remains one of the most important infectious diseases worldwide. For 2011 the World Health Organization estimated that there were 8.7 million new cases of tuberculosis and 1.4 million deaths from tuberculosis.

Objectives

This article gives an overview on the current tuberculosis (TB) situation worldwide, in Europe as well as in Germany. Special attention is given to drug resistance and the HIV and tuberculosis coepidemic as they strongly impact on the epidemiology of tuberculosis.

Methods

International and national epidemiological reports on tuberculosis as well as selected epidemiological studies were considered. Challenges for tuberculosis control in Germany are discussed.

Results

Globally, a slight decline in tuberculosis incidence is currently being observed. This is partly attributed to improvements in diagnostic and therapeutic care and also for HIV infected patients. However, drug resistance rates are causing concern, especially in several newly independent states of the former Soviet Union. Although tuberculosis case numbers and incidences in the European Union and the European Economic Area (EU/EEA) are comparably low, tuberculosis still represents a considerable burden of disease. In Germany, as in several other western European countries with a low incidence of tuberculosis, case numbers are stagnating and childhood tuberculosis is slightly increasing. Therefore, efforts to ensure an effective tuberculosis control cannot be allowed to wane.     

Minimally Invasive Endogastric Removal of Migrated Gastric Band After Endoscopic Failure: How I Do It

Intragastric band migration is a rare and late complication of laparoscopic -adjustable gastric banding and should be recognized by all digestive surgeons. Endoscopic removal is most commonly performed, but surgery is an alternative in cases of endoscopic failure. Many different procedures have been reported. We show here (see Video) a fully laparoscopic endogastric procedure through two 5-mm antral gastrotomies. This technique can also be used to remove benign endogastric tumors. The procedure is safe and provides a large endogastric operative area, with no particular morbidity. Endogastric removal through a fully laparoscopic approach should be considered as the first alternative to endoscopic approach.     

Validity of a single-item measure to assess leg or back pain as the predominant symptom in patients with degenerative disorders of the lumbar spine

Purpose

Recent studies suggest that the location of predominant pain (back or leg) can be a significant predictor of the outcome of surgery for degenerative spinal disorders. However, others challenge the notion that the predominant symptom can be reliably identified. This study examined the validity of a single item used to determine the most troublesome symptom.

Methods

A total of 2,778 patients with degenerative disorders of the lumbar spine scheduled for surgery with the goal of pain relief completed a questionnaire enquiring as to their most troublesome symptom [“main symptom”; back pain (BACK) or leg/buttock pain (LEG)]. They also completed separate 0–10 graphic rating scales for back pain (LBP) and leg/buttock pain (LP) intensity. Receiver operating characteristics (ROC) analysis was used to determine the accuracy with which the “LP minus LBP” score was able to classify patients into their declared “main symptom” group. Sub-studies evaluated the test–retest reliability of the patients’ self-rated pain scores (N = 45) and the agreement between the main symptom declared by the patient in the questionnaire and that documented by the surgeon after the clinical consultation (N = 118).

Results

Test–retest reliability of the back and leg pain scores was good (ICC_2,1 of 0.8 for each), as was patient–surgeon agreement regarding the main symptom (BACK or LEG) (κ value 0.79). In the BACK group, the mean values for pain intensity were 7.3 ± 2.0 (LBP) and 5.2 ± 2.9 (LP); in the LEG group, they were 4.3 ± 2.9 (LBP) and 7.5 ± 1.9 (LP). The area under the curve for the ROC was 0.95 (95 % CI 0.94–0.95), indicating excellent discrimination between the BACK and LEG groups based on the “LP minus LBP” scores. A cutoff score >0.0 for “LP minus LBP” score gave optimal sensitivity and specificity for indicating membership of the LEG group (sensitivity 79.1 %, specificity 95.7 %).

Conclusions

The responses on the single item for the “main symptom” were in good agreement with the differential ratings on the 0–10 pain scales for LBP and LP intensity. The cutoff >0 for “LP minus LBP” for classifying patients as LEG pain predominant seemed appropriate and suggests good concurrent validity for the single-item measure. The single item may be of use in sub-grouping patients with the same disorder (e.g. spondylolisthesis) or as an indication in surgical decision-making.     

Regulation of bone mass by Wnt signaling

Wnt proteins are a family of secreted proteins that regulate many aspects of cell growth, differentiation, function, and death. Considerable progress has been made in our understanding of the molecular links between Wnt signaling and bone development and remodeling since initial reports that mutations in the Wnt coreceptor low-density lipoprotein receptor-related protein 5 (LRP5) are causally linked to alterations in human bone mass. Of the pathways activated by Wnts, it is signaling through the canonical (i.e., Wnt/beta-catenin) pathway that increases bone mass through a number of mechanisms including renewal of stem cells, stimulation of preosteoblast replication, induction of osteoblastogenesis, and inhibition of osteoblast and osteocyte apoptosis. This pathway is an enticing target for developing drugs to battle skeletal diseases as Wnt/beta-catenin signaling is composed of a series of molecular interactions that offer potential places for pharmacological intervention. In considering opportunities for anabolic drug discovery in this area, one must consider multiple factors, including (a) the roles of Wnt signaling for development, remodeling, and pathology of bone; (b) how pharmacological interventions that target this pathway may specifically treat osteoporosis and other aspects of skeletal health; and (c) whether the targets within this pathway are amenable to drug intervention. In this Review we discuss the current understanding of this pathway in terms of bone biology and assess whether targeting this pathway might yield novel therapeutics to treat typical bone disorders.     

Trigeminal neuralgia: evaluation of percutaneous neurodestructive procedures

The treatment of trigeminal neuralgia (TN), which is resistant to medical therapy, has benefited from many surgical techniques. It is not possible, in light of the present level of knowledge, to establish exactly which method is the most suitable. It does, however, seem significant that certain side effects appear, in varying percentages, in all kinds of operations. In 13 years, 2,094 patients suffering from TN have been treated by the authors with percutaneous Gasserian neurolysis, 128 patients with radiofrequency trigeminal neurolysis, and 1,966 with selective ethanolic trigeminal neurolysis (SETN). Our experience treating TN with controlled increments of ethanol by means of a needle introduced through the oval foramen in the Gasserian ganglion is related here. The tip of the needle is accurately placed among the roots desired under fluoroscopic control. The clinical effects on the conscious patient of a prognostic block with local anesthetics are evaluated before producing the neurolysis. Follow-up has been long enough to show that SETN is a highly selective procedure, which shouldn't be underrated in the centers that use it routinely.     

Poster 12: Stay well and healthy! An in-home preventive health care program for persons aging with developmental disability

Objective: To pilot an intervention to prevent functional decline and health problems among persons with intellectual and developmental disability aging in the community. Design: Pilot for a large randomized trial. Setting: Private residences and group homes. Participants: 201 adults with intellectual and developmental disability, aged 32 years and older, were randomly assigned to an advance practice nurse (APN) intervention (n=101) or health-risk appraisal and feedback only (HRA) intervention (n=100). Interventions: The APN group received in-home multidimensional assessment, targeted recommendations, and quarterly follow-up visits for up to 1 year. The HRA group received an in-home interview with written feedback. Main Outcome Measures: Health, functional status, and risks; use of acute medical services; and feasibility assessment. Results: Assessment tools and interventions were demonstrated to be feasible in a population with mild to moderate intellectual and developmental disability. Recruitment and randomization were successful (avg age, 41y; 52% men). High levels of health risks were identified (mean, 7.6; range, 1-20y); 23.4% reported “fair” or “poor” general health; 16.4% reported probable depression; 34.5% reported recent falls; 36.8% reported fair or poor oral health; and 32.7% reported pain moderate or worse. Conclusion: Interventions are feasible for trials in this population and have broad applicability to other populations aging with disability.
