BACKGROUND: Although there have been case reports describing trocar site herniation after laparoscopic fundoplication, its overall prevalence and the risk factors for its development are unclear.METHODS: The records of 320 patients undergoing primary laparoscopic fundoplication as treatment for gastroesophageal reflex disease (GERD) or hiatal hernia between 1991 and 1999 were reviewed retrospectiv

Forty patients with a mean age of 45 (range 22-65) years were operated on between 1982 and 1985 for gastro-oesophageal reflux disease with a short floppy 360 degree fundoplication. The results of the operation were determined by endoscopy, oesophageal manometry, ambulatory 24-h pH recording and symptom evaluation 6 months and 5 years after operation. These results were compared with findings in he

OBJECTIVE: To evaluate differences in clinical appearance and survival rates in patients operated on for adenocarcinoma in the distal esophagus with and without Barrett epithelium.DESIGN: Prospective clinical study.SETTING: University hospital, Sweden.PATIENTS: Fifty-four patients with adenocarcinoma in the distal esophagus with (n = 17) or without (n = 37) Barrett epithelium.INTERVENTION: Esophag

BACKGROUND: The act of swallowing after gastric pull-up esophagectomy has not been thoroughly investigated. The aim of this study was to evaluate deglutition in the esophageal remnant and in the gastric conduit in patients who have undergone this operation.METHODS: The residual radionuclide activity was measured 15 seconds after a swallow in the esophageal remnant and at intervals up to a maximum

Purpose: According to guideline recommendations, chest compressions (CC) during cardiopulmonary resuscitation (CPR) should be performed at a rate of 100 - 120 per minute, with a CC fraction (CCF) of ≥80%. The aim of this work is to explore whether CC quality differs between advanced life support (ALS) and basic life support (BLS) performed by two rescuers. Method: Cardiopulmonary resuscitation was

BACKGROUND: Currently, only a limited number of molecular biomarkers for malignant melanoma exist. This is the case for both diagnosing the disease, staging, and efficiently measuring the response to therapy by tracing the progression of disease development and drug impact. There is a great need to identify novel landmarks of disease progression and alterations.METHODS: Matrix-assisted laser desor

This article aims at describing a logistic approach for prolonged resuscitation efforts in the cath-lab using mechanical chest compressions (MCC) during simultaneous percutaneous coronary intervention (PCI).

A precision luminosity measurement is of critical importance for the ATLAS physics program, both for searches for new physics as well as for precision measurements of Standard Model crosssections. The calibration of the luminosity is based on so-called van der Meer scans. The calibration determines the convolved beam sizes in the vertical and horizontal directions, and together with the precise kn

In this paper, we quantify the degree of ganglion cell layer thinning due to retrograde trans-synaptic degeneration (RTSD) from retro-geniculate damage in six cases who had homonymous visual field defects known since childhood. Three had prenatal injuries, occurring close to mid-gestation and in the first parts of the early and late third trimester, respectively, and representing injuries at diffe

Self-treatment techniques in patients with paroxysmal atrial fibrillation (PAF) have seldom been described. It has been suggested that PAF attacks might be initiated by changes in the tonus of the autonomic nervous system. Our aim was to study patients’ measures to terminate PAF attacks and to evaluate the possible influence of the autonomic nervous system on start and stop mechanisms.

In this article we will discuss the basic calculational concepts to simulate particle physics events at high energy colliders. We will mainly focus on the physics in hadron colliders and particularly on the simulation of the perturbative parts, where we will in turn focus on the next-to-leading order QCD corrections.
