Total hip replacement produces significant postoperative pain. Psoas compartment block is the most effective block of the lumbar plexus in terms of pain relief and reduced blood loss. It is a proven regional technique for analgesia and anaesthesia during and after total hip replacement conferring a number of benefits to the patient.

Treatment options for osteosarcoma may include surgery, chemotherapy, and radiotherapy. Unfortunately, many patients eventually relapse, resulting in an unsatisfactory outcome.

Lymphatic malformations that involve the nervous system are uncommon. The authors review their experience with involvement of the brachial plexus and its branches by cystic hygromas. A retrospective review of the authors' experience with pathology of the pediatric brachial plexus revealed 4 cases involving patients with compression of this structure and its branches due to cystic hygroma.

Eight Holstein calves with an ultrasonic flow probe around the superior mesenteric artery and catheters in the carotid artery and mesenteric vein were paired by age and randomly assigned to treatment of a control (0.5% of BSA in saline; n=4) or GLP-2 (50 μg/kg of body weight of bovine GLP-2 in BSA; n=4) given subcutaneously every 12h for 10 d.

Background: To date, there is no information on anaesthetists' practice of chronic pain management in the Republic of Ireland.
Aims: To describe the pattern of chronic pain practice (CPP) among consultant anaesthetists in Ireland.
Methods: A detailed questionnaire was sent to all consultant anaesthetists in the Republic of Ireland (n = 254).
Chronic emesis may result from a variety of causes. To the authors' knowledge, compression of the area postrema by regional vessels resulting in chronic emesis has not been reported. The authors report on a child who presented with chronic medically intractable emesis and significant weight loss requiring jejunostomy feeding.

Purpose: Numerous preclinical studies have demonstrated that angiogenesis inhibitors can increase the efficacy of radiotherapy (RT). We sought to examine the safety and efficacy of bevacizumab (BV) and RT in soft tissue sarcomas and explore biomarkers to help determine the treatment response.
Methods And Materials: Patients with ≥5 cm, intermediate- or high-grade soft tissue sarcomas at significant risk of local recurrence received neoadjuvant BV alone followed by BV plus RT before surgical resection.
Glucagon-like peptide-2 (GLP-2) is a potent trophic gut hormone, yet its function in ruminants is relatively unknown. Experiment 1 was conducted as a pilot study to establish the presence of GLP-2 in ruminants and to ascertain whether it was responsive to increased nutrition, as in non-ruminants. Concentrations of intact GLP-2 in the blood and gut epithelial mRNA expression of proglucagon (GCG) and the GLP-2 receptor (GLP2R) were measured in 4 ruminally, duodenally, and ileally cannulated steers.

We present a case of epithelioid sarcoma in which complete remission of pulmonary metastases was observed after treatment with a single agent, navelbine, a vinca alkaloid, and a potential therapeutic agent. The patient has been persistently free of metastases for 4 years since treatment with navelbine.

This is a report of long-term (≥5 years) follow-up in patients with high-grade, high-risk soft tissue sarcomas treated with neoadjuvant chemotherapy, preoperative radiotherapy (RT), and adjuvant chemotherapy.
Methods: Patients with high-grade soft tissue sarcoma≥8 cm in diameter of the extremities and body wall received 3 cycles of neoadjuvant chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine) and preoperative RT (44 grays administered in split courses), and 3 cycles of postoperative chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine).
Primary renal extraskeletal Ewing sarcoma (EES) is rare but well known to be aggressive, less responsive to the treatment, and has early predilection for metastases. Metastases at the time of diagnosis to the lungs or bones are associated with poor outcome. We present a case of primary renal EES in 57-year-old woman with multiple metastases to the lungs at the time of diagnosis with complete remission of the disease for the last 8 years following multimodality treatment Multidisciplinary approach for the management of EES has definitely improved the quality of life and the survival of the patients.

Type three secretion systems (TTSSs) are virulence factors found in many pathogenic Gram-negative species, including the family of pathogenic Yersinia spp. Yersinia pseudotuberculosis requires the translocation of a group of effector molecules, called Yops, to subvert the innate immune response and establish infection. Polarized transfer of Yops from bacteria to immune cells depends on several factors, including the presence of a functional TTSS, the successful attachment of Yersinia to the target cell, and translocon insertion into the target cell membrane.

Design: Prospective, observational clinical study.
Setting: Orthopedic and Radiology departments of a regional hospital.
Background: We sought to reduce local recurrence for retroperitoneal sarcomas by using a coordinated strategy of advanced radiation techniques and aggressive en-bloc surgical resection.
Methods: Proton-beam radiation therapy (PBRT) and/or intensity-modulated radiation therapy (IMRT) were delivered to improve tumor target coverage and spare selected adjacent organs. Surgical resection of tumor and adjacent organs was performed to obtain a disease-free anterior margin.
Ruminal cannulation techniques are frequently used to study fermentation in the ruminant forestomach. Unsatisfactory results with the traditionally applied procedure for cannulation of young calves stimulated the development of a simpler and more robust procedure; this procedure was tested for effects on performance traits and gross anatomy of the gastrointestinal tract compared with a control group not undergoing surgery. Five calves were ruminally cannulated at approximately 10 d of age and 5 matching calves were used as controls.

Methods: An initial cadaver study was used to develop a technique that was used in the clinical setting on patients undergoing breast cancer surgery.
Results: Paravertebral catheters were correctly placed in the cadaveric trial in 8 of 10 attempts.
Objective: To determine the sensory innervation of the penis, as regional anaesthesia is often used either for postoperative analgesia or as the sole anaesthetic technique for circumcision. Since first described in 1978 the dorsal penile nerve block has become the standard technique, but some blocks are ineffective; a better understanding of the sensory innervation of the penis might improve the efficacy of the dorsal penile block technique.
Patients And Methods: In 13 men undergoing circumcision with local anaesthetic, cutaneous sensation was tested before and after infiltration of the dorsal aspect of the penis, and then again after infiltration of the ventral aspect.
Two experiments were conducted to determine the effect of ruminal protein degradability and supplementation frequency on intake, apparent digestibility, N retention, and nutrient flux across visceral tissues of lambs fed a low-quality forage diet. In both experiments, wethers were fed a basal diet of mature crested wheatgrass hay (4.2% CP) for ad libitum consumption plus 1 of 4 supplements: 1) a high RDP supplement provided daily (RDP-D), 2) the high RDP supplement provided on alternate days (RDP-A), 3) a high RUP provided on alternate days (RUP-A), or 4) a 50:50 mixture of the RDP and RUP supplements provided on alternate days.
View Article and Find Full Text PDFIn mammals, the absorption of monosaccharides from small intestinal lumen involves at least 3 sugar transporters (SugT): sodium-dependent glucose transporter 1 (SGLT1; gene SLC5A1) transports glucose and galactose, whereas glucose transporter (GLUT) 5 (GLUT5; gene SLC2A5) transports fructose, across the apical membrane of enterocytes. In contrast, GLUT2 (gene SLC2A2) transports all of these sugars across basolateral and apical membranes. To compare the distribution patterns and sensitivity with nutritional regulation of these 3 SugT mRNA in beef cattle small intestinal tissue, 18 ruminally and abomasally catheterized Angus steers (BW approximately 260 kg) were assigned to water (control), ruminal cornstarch (partially hydrolyzed by alpha-amylase; SH), or abomasal SH infusion treatments (n = 6) and fed an alfalfa-cube-based diet at 1.
