Measurement properties of the pressure biofeedback unit in the evaluation of transversus abdominis muscle activity: a systematic review  

British Library Electronic Table of Contents (United Kingdom)

Background: Measurements from pressure biofeedback units (PBUs) can be used to evaluate the activity of the transversus abdominis (TrA) muscle indirectly. These measurements can classify patients or monitor the progress of treatment programmes for people with low back pain. Objective: To systematically review studies on the measurement properties of PBUs for the assessment of TrA activity. Data sources: Eligible studies were identified through searches of PUBMED, CINAHL and BIREME (1990 to 2009). In addition, hand searches of journals and citation tracking were performed. Study selection: Full-text studies involving any type of clinimetric tests of PBU measurement for the assessment of TrA activity were selected. Data extraction: Two independent reviewers selected the studies, extracted th...

Simulation-based training improves applied clinical placement of ultrasound-guided PICCs  

British Library Electronic Table of Contents (United Kingdom)

Purpose Skilled placement of peripherally inserted central catheters (PICC) has a profound impact on patient well-being and costs of care. The use of ultrasound-guided methods and prescribed training for cannulation skills are evidence-based practice recommendations. The purpose of this study was to compare two methods of PICC instruction on the acquisition of applied skills. Methods Residents were randomly assigned to one of two groups (N?=?16/16) of this blind-rater study and were trained to perform ultrasound-guided PICC cannulation using either simulation or apprenticeship methods. All residents were assessed placing a PICC in applied clinical patient care. Results Residents who completed simulation training had significantly better transfer of skills to applied clinical practice than ...

Hepatosplenic T-cell lymphoma is a distinct rare entity: Diagnosis by fine-needle aspiration cytology  

British Library Electronic Table of Contents (United Kingdom)

Abstract In this brief report, we have described the fine-needle aspiration cytology (FNAC) of a hepatosplenic T-cell lymphoma (HSTCL) in a 60-year-old female patient. The patient complained of fever and heaviness of left upper abdomen. Ultrasound-guided FNAC of the spleen showed immature lymphoid cells, and a diagnosis of primary non-Hodgkin lymphoma of spleen was offered. Subsequently, the patient underwent splenectomy and wedge biopsy of liver that confirmed the cytological diagnosis. The lymphoma cells were positive for CD3 immunostain. Primary hepatosplenic T-cell lymphoma is a rare entity and may often pose diagnostic problems on FNAC. Diagn. Cytopathol. 2010. 2010 Wiley-Liss, Inc.

Magnetic resonance imaging of the urogenital diaphragma in comparison with conventional histomorphological findings (the controversy about the deep transverse muscle of perineum); Kernspintomographische Untersuchungen des Diaphragma urogenitale im Vergleich mit korrespondierenden histomorphologischen Befunden (der Streit um den Misculus transversus perinei profundus)  

Energy Technology Data Exchange (ETDEWEB)

The transversus perinei profundus muscle is a well known structure in found anatomical textbook. Fibres of this muscle are believed to form the so-called external urethral sphincter (musculus sphincter urethrae). Recently histomorphologic investigations have shown that there is no muscular connection between the musculus sphincter urethrae (external sphincter) and the muscle system of the pelvic floor. Furthermore, the external sphincter was found to be divided into parts: The transversely striated part (musculus sphincter urethrae transversostriatus) and the smooth part (musculus sphincter urethrae glaber). Similar to histomorphologic investigations, contrast-enhanced MR imaging has shown the musculus sphincter urethrae to be surrounded by fatty and connective tissue only. Neither in MRI nor in anatomical slices can any connection between the urethral sphincter and the muscle system of the pelvic floor be found. Thus, on the basis of the results presented in this ...

Muscarinic and nicotinic activities of the novel acetylcholine analog acetylselenonium choline.  

Science.gov (United States)

The present paper further characterizes the cholinergic properties of acetylselenonium choline (ASeCh, (CH3)2Se+CH2CH2OCOCH3). The data demonstrate that ASeCh possesses muscarinic receptor agonist properties as evidenced by vasodepressor and smooth muscle contractile activities which are enhanced by physostigmine and antagonized by atropine. ASeCh also possessed nicotinic agonist activity on frog rectus abdominis tissue which was potentiated by physostigmine, and blocked by d-tubocurarine. The relative potencies of ASeCh ranged from approximately 1% to approximately 6% of the potency of acetylcholine in the three types of preparations examined. PMID:1435078

Transluminal radio-frequency thermal ablation using a stent-type electrode: an experimental study  

Energy Technology Data Exchange (ETDEWEB)

To assess the feasibility of transluminal radiofrequency thermal ablation using a stent-type electrode and to determine, by means of in-vivo and in-vivo animal studies, the appropriate parameters. In-vivo: the radiofrequency electrode used was a self-expandable nitinol stent with 1cm insulated ends. A stent was placed in the portal vein of bovine liver, and ablations at target temperatures of 70, 80, 90, and 100 .deg. C were performed. Ablated sizes were measured longitudinally. In vivo: four mongrel dogs were anesthetized, and a stent was inserted in the common bile duct under fluoroscopic guidance through an ultrasound-guided gall bladder puncture site. The ablation temperature was set at 80 .deg. C, and each dog underwent proximal and distal esophageal ablations lasting 12 minutes. They were sacrificed immediately. In-vivo: ablated sizes showed significant correlation with target temperatures (r>0.04; p<0.05). Although most lesions were fusiform, ...

Endobronchial ultrasound with transbronchial needle aspiration for restaging the mediastinum in lung cancer  

DEFF Research Database (Denmark)

Purpose To investigate the sensitivity and accuracy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for restaging the mediastinum after induction chemotherapy in patients with non-small-cell lung cancer (NSCLC). Patients and Methods One hundred twenty-four consecutive patients with tissue-proven stage IIIA-N2 disease who were treated with induction chemotherapy and who had undergone mediastinal restaging by EBUS-TBNA were reviewed. On the basis of computed tomography, 58 patients were classified as having stable disease and 66 were judged to have had a partial response. All patients subsequently underwent thoracotomy with attempted curative resection and a lymph node dissection regardless of EBUS-TBNA findings. Results Persistent nodal metastases were detected by using EBUS-TBNA in 89 patients (72%). Of the 35 patients in whom no metastases were assessed by EBUS-TBNA, 28 were found to have residual stage IIIA-N2 disease at ...

Anatomic and radiologic correlations in spontaneous hematomas of the rectus abdomninis muscles; Correlazioni anatomo-radiologiche negli ematomi spontanei dei muscoli retti dell'addome  

Energy Technology Data Exchange (ETDEWEB)

Rectus sheath hematomas are a frequent but sometimes misdiagnosed disease in patients under anticoagulative drugs, hemodialysis, or simply in the elderly. The most frequent localization is in the lower part of the abdomen: the explanation lies in the anatomy of the abdominal wall, especially in the arcuate line of the rectus sheath. Aim of this work is to explain the reason of the almost constant location correlating the anatomy with the CT features. The rectus abdominis muscle lies between the aponeuroses of the transverse and oblique muscles which form the so called rectus sheath. This arrangement is found from the costal arch to a level approximately between the umbilicus and the pubic symphisis, where the rear layer of the rectus sheath ends with a curved edge, called the arcuate or semicircular line of Douglas. Beneath this line the aponeuroses of the three muscles pass in front of the rectus which is separated from the peritoneum only by the fascia ...
