Computed Tomography-Guided Placement of Sacral Electrodes.

Background: The current approach to performing sacral neuromodulation consists of a two-stage procedure, the first of which includes insertion of the sacral electrode under fluoroscopic visualization of the S3 foramen. Alternatively, in certain situations computed tomography (CT)-guided insertion can be used.

Objectives: To evaluate the use of CT in cases of reinsertion of the electrode due to infection, dislocation, or rupture.

Histiocytic Sarcoma.

Histiocytic sarcoma (HS) is a rare hematopoietic malignancy originating from the monocyte/macrophage bone marrow lineage. HS can occur in isolation or in association with other hematological neoplasms such as non-Hodgkin lymphoma (NHL), myelodysplasia, or acute leukemia. Clinically, HS can affect lymph nodes, gastrointestinal tract, skin, bone marrow, and spleen as well as the central nervous system.

Visceral adiposity but not subcutaneous fat associated with improved outcome of patients with acute cholecystitis.

Background: The aim of this study to study the effect of visceral and subcutaneous fat tissue mass on short- and long-term prognosis of patients with acute calculus cholecystitis (ACC).

Methods: Retrospective analysis of medical records. Included were all patients admitted because of ACC.

The value of testicular ultrasound in the prediction of the type and size of testicular tumors.

Objectives: Ultrasound (US) is often used for the work-up of testicular pathology. The findings may implicate on its management. However, there is only scant data on the correlation between US findings and testicular tumor type and size.

Correct depth of insertion of right internal jugular central venous catheters based on external landmarks: avoiding the right atrium.

Objective: Radiographically, a central venous catheter (CVC) tip should lie at the level of the right tracheobronchial angle. Precalculation of length of CVC insertion may avoid unnecessary catheter malposition. The purpose of this study was to assess the accuracy of a method of CVC positioning, based on external topographic landmarks.

Leiomyosarcoma of the superior vena cava: Resection with vascular reconstruction - case report and review of the literature.

The present report describes a case of pedunculated intraluminal leiomyosarcoma of the superior vena cava, extending to the right atrium, that was successfully resected surgically. Superior vena cava reconstruction was performed using bovine pericardial graft, saving the sinus node. The pathological variants of this neoplasm according to the anatomical site of the tumour are described.
