Small intestinal intraluminal pressure activity and aboral traction forces were explored in 19 healthy volunteers using a combined manometry and traction force detecting assembly sited in the upper small intestine. Each aboral traction event was classified as being associated with either a propagating or a stationary contraction and its force measured. During phase I no contractions or traction...

Colorectal endoscopic submucosal dissection (ESD) still remains a technically difficult procedure. The maintenance of tissue tension and good submucosal exposure during dissection is one of the most important factors for an effective and safe dissection. Although various traction methods have been developed, traction by gravity is one of the most useful method for colorectal ESD. Traction using...

The breakage of an epidural catheter is an extremely rare complication. We describe a unique case where a retained epidural catheter fragment after epidural anesthesia was treated by surgery. The epidural catheter broke during its removal, requiring surgery to remove the retained catheter. Intraoperatively, the removal of the catheter was attempted by simple traction, but was impossible because...

INTRODUCTION Traction alopecia is hair loss caused by prolonged or repetitive tension on the hair. Diagnostic challenges are encountered when the clinical suspicion is not high and when a history of traction is remote or not obtained. We have made the observation that the presence of retained hairs along the frontal and/or temporal rim, which we termed the "fringe sign," is a finding seen in bo...

PURPOSE The purpose of the study was to assess the contribution of a lateral extraoral radiograph for diagnosing the relation between the root of intruded maxillary primary incisors and their permanent successors. METHODS Three pediatric dentists examined intruded primary teeth 0-7 days after injury. The relations between the primary and permanent teeth were assessed in three separate steps: ...

Background. Failure to achieve delayed primary fascial closure (DPFC) is one of the main complications of open abdomen (OA), certainly when abdominal sepsis is present. This retrospective cohort study aims to evaluate the effect of combined therapy of vacuum-assisted mesh-mediated fascial traction and topical instillation (VAWCM-instillation) on DPFC in the open septic abdomen. Methods. The pat...

To understand how adherent cells regulate traction forces on their surrounding extracellular matrix (ECM), quantitative techniques are needed to measure forces at the cell-ECM interface. Microcontact printing is used to create a substrate of 1 μm diameter circles of ECM ligand to experimentally study the reconstruction of traction stresses at constrained, point-like focal adhesions. Traction re...

OBJECTIVE To describe our experience with removal of pacing lead in children using different techniques. PATIENTS AND METHODS Between 1999 and 2006, removal of 39 leads was attempted in 30 patients: 21 males and 9 females aged 4-21 years (mean 12 +/- 5 years). Sixteen patients had previous corrective cardiac surgery. The leads had been implanted for 46 +/- 31 months (range 1-120 months). The ...

INTRODUCTION Unreduced elbow dislocation is every elbow dislocation older than one week. It may be treated non-operatively (with prereduction traction) or surgically. The treatment goals are: to reduce pain, to establish joint stability and movements. There are a lot of techniques described in literature, series are relatively small, mostly case reports. Multicentric studies have not been done....
