Abstract

Purpose

Although a number of genetic studies have attempted to link organic cation transporter 1/2 (OCTN1/2) polymorphisms to susceptibility of Crohn's disease (CD), the results were often inconsistent. The present study aimed at investigating the associations.

Methods

The PubMed, EBSCO, and BIOSIS databases were searched to identify eligible studies which were published in English before April 2011. The association was assessed by odds ratio (OR) with 95% confidence intervals (CI).

Results

A total of 15 case–control studies, containing 4,489 cases/5,351 controls for OCTN1 and 4,474 cases/5,377 controls for OCTN2 were included. Overall, significant associations were found between OCTN1/2 polymorphisms and susceptibility of Crohn's disease for all genetic models. In the subgroup analyses, significant associations were found in the Caucasian population for OCTN1 (TT vs. CC: OR = 1.425, 95% CI 1.247–1.628; TT vs. CT: OR = 1.299, 95% CI 1.149–1.468; dominant model: OR = 1.344, 95% CI 1.197–1.508; and recessive model: OR = 1.179, 95% CI 1.066–1.305) and for OCTN2 (CC vs. GG: OR = 1.309, 95% CI 1.078–1.588; CC vs. CG: OR = 1.200, 95% CI 1.002–1.438; dominant model (OR = 1.231, 95% CI 1.036–1.462; recessive model: OR = 1.148, 95% CI 1.031–1.279). Significant associations were not found in the East Asian population.

Conclusions

This meta-analysis suggests that OCTN1/2 polymorphisms were associated with susceptibility of CD in the Caucasian population but not in the East Asian population.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

S2e-Leitlinie „Distale Radiusfraktur“

Radiusfraktur BDC Leitlinien Webinare
CME: 2 Punkte

Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
