Intra-abdominal Content Movement in Prone Versus Lateral Decubitus Position Lateral Lumbar Interbody Fusion (LLIF).

Study Design: A prospective, anatomical imaging study of healthy volunteer subjects in accurate surgical positions.

Objective: To establish if there is a change in the position of the abdominal contents in the lateral decubitus (LD) versus prone position.

Summary Of Background Data: Lateral transpsoas lumbar interbody fusion (LLIF) in the LD position has been validated anatomically and for procedural safety, specifically in relation to visceral risks.

Diffusion-weighted magnetic resonance (DW-MR) neurography of the lumbar plexus in the preoperative planning of lateral access lumbar surgery.

Purpose: Magnetic resonance (MR) neurography has been used to evaluate entire nerves and nerve bundles by providing better contrast between the nerves and the surrounding tissues. The purpose of the study was to validate diffusion-weighted MR (DW-MR) neurography in visualizing the lumbar plexus during preoperative planning of lateral transpsoas surgery.

Methods: Ninety-four (188 lumbar plexuses) spine patients underwent a DW-MR examination of the lumbar plexus in relation to the L3-4 and L4-5 disc spaces and superior third of the L5 vertebral body.

Ultrasound and magnetic resonance imaging findings in Schistosomiasis mansoni: expanded gallbladder fossa and fatty hilum signs.

Introduction: There is no study relating magnetic resonance imaging (MRI) to ultrasound (US) findings in patients with Schistosomiasis mansoni. Our aim was to describe MRI findings inpatients with schistosomal liver disease identified by US.

Methods: Fifty-four patients (mean age 41.

Study of arterial pattern of 200 renal pedicle through angiotomography.

Objective: To investigate the prevalence and distribution of renal arteries and their branches in vivo, correlating the particularities found in them with sex and laterality.

Methods: Two hundred renal pedicles were studied by CT angiography and its arteries analyzed according to number, position of origin, size, length and trajectory in relation to renal segments. Its frequency and laterality were surveyed regarding gender and age.

Schistosoma mansoni: magnetic resonance analysis of liver fibrosis according to WHO patterns for ultrasound assessment of schistosomiasis-related morbidity.

For the last two decades, ultrasound (US) has been considered a surrogate for the gold standard in the evaluation of liver fibrosis in schistosomiasis. The use of magnetic resonance imaging (MRI) is not yet standardised for diagnosing and grading liver schistosomal fibrosis. The aim of this paper was to analyse MRI using an adaptation of World Health Organization (WHO) patterns for US assessment of schistosomiasis-related morbidity.

Imaging techniques and histology in the evaluation of liver fibrosis in hepatosplenic schistosomiasis mansoni in Brazil: a comparative study.

Few publications have compared ultrasound (US) to histology in diagnosing schistosomiasis-induced liver fibrosis (LF); none has used magnetic resonance (MR). The aim of this study was to evaluate schistosomal LF using these three methods. Fourteen patients with hepatosplenic schistosomiasis admitted to hospital for surgical treatment of variceal bleeding were investigated.

[The problematic aspects of the family caregiver of people who suffered strokes].

The purpose of this study was to identify the problematic aspects of the families of people who were hospitalized because of strokes, and discuss the difficulties of the family caregiver toward household care. The sample consisted of 154 families of patients admitted in a public hospital in Fortaleza, Ceará state, Brazil. The results showed that most caregivers are women, 104 (67.

Imaging techniques in the evaluation of morbidity in schistosomiasis mansoni.

Over the last 20 years a great advance has been observed in many aspects of medicine, and the advent of novel imaging techniques is certainly amongst the most important. In schistosomiasis these new methods caused a revolution in the definition of the clinical forms of the disease and in the evaluation of its complications, such as, liver fibrosis, pulmonary hypertension and neuroschistosomiasis, as never before. Herein we present an overview of the image methods used to diagnose schistosomiasis mansoni nowadays.

Disagreement between ultrasound and magnetic resonance imaging in the identification of schistosomal periportal fibrosis.

Abdominal ultrasound (US) has been widely used in the evaluation of patients with schistosomiasis mansoni. It represents an important indirect method of diagnosis and classification of the disease, and it has also been used as a tool in the evaluation of therapeutic response and regression of fibrosis. We describe the case of a man in whom US showed solid evidence of schistosomal periportal fibrosis and magnetic resonance imaging revealed that periportal signal alteration corresponded to adipose tissue which entered the liver together with the portal vein.

Magnetic resonance imaging and ultrasound in hepatosplenic schistosomiasis mansoni.

We report the findings of abdominal ultrasound and magnetic resonance imaging observed in a patient with advanced schistosomiasis mansoni. A 25-year-old man with hepatosplenic schistosomiasis and variceal bleeding confirmed by upper endoscopy was submitted to abdominal ultrasound and magnetic resonance imaging. During surgery for portal hypertension, a liver biopsy was taken and the diagnosis of Symmers' fibrosis was confirmed.

[Schistosomal myeloradiculopathy].

Schistosomal myeloradiculopathy is the most severe and disabling ectopic form of schistosomiasis mansoni. Its prevalence in endemic areas has been underestimated. The diagnosis relies on the presence of low thoracic/upper lumbar neurological symptoms, demonstration of the Schistosoma mansoni infection by microscopic or serologic techniques, and exclusion of other causes of transverse myelitis.
