Stapled transanal rectal resection for symptomatic intussusception: morphological and functional outcome.

Introduction: Stapled transanal rectal resection (STARR) was developed to correct intussusception causing obstructed defecation. Some patients, however, do not profit from this operation as anticipated. We aimed to study the relationship between functional outcome and rectal morphology after STARR.

A salvage procedure for failed weaver-dunn reconstruction.

The Problem: The failure rate after surgical acromioclavicular (AC) joint stabilization is of up to 10%. For revision, several techniques including modifications of the Weaver-Dunn procedure have been suggested. However, patients with failure of such revision techniques represent a special challenge due to the altered anatomic relationships and the lack of stabilizing structures.

Whole-body MRI versus whole-body MDCT for staging of multiple myeloma.

Objective: The purpose of our study was to compare the detection rate of bone manifestations of multiple myeloma in whole-body MRI compared with MDCT and to assess accuracy in staging.

Subjects And Methods: Forty-one patients with histologically confirmed myeloma were prospectively examined with a whole-body MDCT protocol and whole-body MRI on a 1.5-T system.

Cine-MRI detection of intraabdominal adhesions: correlation with intraoperative findings in 89 consecutive cases.

Background: This study aimed to evaluate the accuracy of functional cine-MRI in detecting abdominal adhesions.

Methods: For this study, 89 consecutive patients with adhesion-related complaints after previous abdominal surgery underwent preoperative workup including cine-MRI in transverse and sagittal orientations for a dynamic examination of an induced visceral slide. An abdominal map consisting of nine segments was created to document the location and extent of the adhesion.

Atypical incarcerated abdominal wall hernia mimicking acute diverticulitis.

An 89-year-old female presented with typical symptoms of acute diverticulitis. Abdominal CT revealed an abdominal wall hernia with signs of acute incarceration in the lateral part of the transverse abdominis muscle and rupture of the transversalis fascia. The findings were confirmed intraoperatively.

Trauma surgeons' attitude towards family presence during trauma resuscitation: a nationwide survey.

Objective: Trauma is the foremost cause of death in young patients. Not only the patient but also the family experience the consequences of trauma. Interactions of medical staff with family members in the emergency situation may fail psychological and emotional needs.

Clinical evaluation of a computer-aided diagnosis (CAD) prototype for the detection of pulmonary embolism.

Rationale And Objectives: To evaluate the performance of a prototype computer-aided diagnosis (CAD) tool using artificial intelligence techniques for the detection of pulmonary embolism (PE) and the possible benefit for general radiologists.

Materials And Methods: Forty multidetector row computed tomography datasets (16/64- channel scanner) using 100 kVp, 100 mAs effective/slice, and 1-mm axial reformats in a low-frequency reconstruction kernel were evaluated. A total of 80 mL iodinated contrast material was injected at a flow rate of 5 mL/seconds.

Assessment of colonic transit time using MRI: a feasibility study.

The aim of this pilot study was to evaluate a new, non-invasive examination method using MRI for the quantification of the colonic transit time after oral administration of gadolinium-saline solution filled capsules. Healthy volunteers without previous or acute symptoms of gastrointestinal disorders were enrolled. After a 3-day diet for the standardization of gastrocolonic content the volunteers swallowed five Gd-DTPA/saline 0.

Significance of Elecsys S100 immunoassay for real-time assessment of traumatic brain damage in multiple trauma patients.

Background: The neuroprotein S100 released into the circulation has been suggested as a reliable marker for primary brain damage. However, safe identification of relevant traumatic brain injury (TBI) may possibly be hampered by S100 release from peripheral tissue. The objective of this study was to measure early S100 levels using the Elecsys S100 immunoassay for real-time assessment of severe TBI in multiple trauma.

A rare differential diagnosis to occupational neck pain: bilateral stylohyoid syndrome.

Chronic neck pain is widely prevalent and a common source of disability in the working-age population. Etiology of chronic neck pain includes neck sprain, mechanical or muscular neck pain, myofascial pain syndrome, postural neck pain as well as pain due to degenerative changes. We report the case of a 42 year old secretary, complaining about a longer history of neck pain and limited movement of the cervical spine.

Intrathecal and systemic concentration of NT-proBNP in patients with severe traumatic brain injury.

Outcome of patients suffering from traumatic brain injury (TBI) depends on the development of secondary brain damage. In this context, recent studies underlined the role of the natriuretic peptides- atrial natriuretic peptide and brain natriuretic peptide (BNP)-in aneurysmatic subarachnoidal hemorrhage (SAH). Especially BNP correlates with intracranial pressure and clinical outcome after SAH.

Dual-source CT cardiac imaging: initial experience.

The relation of heart rate and image quality in the depiction of coronary arteries, heart valves and myocardium was assessed on a dual-source computed tomography system (DSCT). Coronary CT angiography was performed on a DSCT (Somatom Definition, Siemens) with high concentration contrast media (Iopromide, Ultravist 370, Schering) in 24 patients with heart rates between 44 and 92 beats per minute. Images were reconstructed over the whole cardiac cycle in 10% steps.

Assessment of large bowel motility by cine magnetic resonance imaging using two different prokinetic agents: a feasibility study.

Objectives: We sought to assess large bowel motility, induced by 2 prokinetic agents, senna tea and erythromycin, using functional cine magnetic resonance imaging (MRI).

Materials And Methods: Twelve volunteers underwent functional cine MRI before and after the administration of senna tea or erythromycin. The protocol consisted of 2 sets of repeated measurements using coronal T2-weighted HASTE sequences, adjusted to the course of the colon.

Role of MRI for the diagnosis and prognosis of multiple myeloma.

For the correct staging of patients with multiple myeloma sensitive detection is mandatory in order to estimate prognosis and to decide for adequate therapy. Magnetic resonance imaging (MRI) is superior to radiography for both, focal and diffuse involvement. Five different infiltration patterns can be differentiated: (1) normal appearance of bone marrow despite minor microscopic plasma cell infiltration, (2) focal involvement, (3) homogeneous diffuse infiltration, (4) combined diffuse and focal infiltration, (5) "salt-and-pepper"-pattern with inhomogeneous bone marrow with interposition of fat islands.
