Avulsion of the peripheral nerve of the trigeminal nerve

There are variety of surgical methods in treating trigeminal neuralgia. They can all be devided in two large groups: less invasive procedures and decopmressive procedures in the region of pontocerebelar angle. Peripheral neurectomy, exeresis or avulsion of peripheral branches of trigeminal nerv are methods for elderly patients with serious cardiopulmonal disturbances. We performed avulsion of peripheral branches at 58 patients, all older than 60 years. In 32 patients we did avulsion of only one of three branches of trigeminal nerv, while in 26 patients the combined avulsion of two branches was performed. There were no postoperative complications.     

Hypoglycemic effect of aqueous shallot and garlic extracts in rats with fructose-induced insulin resistance

The present study has been carried out to investigate the effect of aqueous extract of shallot (Allium ascalonicum) and garlic (Allium satium) on the fasting insulin resistance index (FIRI) and intraperitoneal glucose tolerance test (IPGTT) of fructose-induced insulin resistance rats. Male albino Wistar rats were fed either normal or high-fructose diet for a period of eight weeks. Fasting blood glucose level, fasting blood triglyceride level, FIRI, and the area under the glucose tolerance curve were significantly elevated in fructose-fed animals. Fructose-induced insulin resistance rats treated by aqueous shallot or garlic extract (500 mg/kg body weight/day, i.p.) for duration of eight weeks. Control animals only received normal saline (0.9%). The results showed that neither shallot nor garlic extracts significantly altered the FIRI and the IPGTT at the fourth week after treatment. The fasting blood glucose in fructose-induced insulin resistance animals has been significantly decreased in 8-week treated animals by both shallot and garlic extracts. Shallot extract administration, but not garlic extract, for a period of eight weeks can significantly improve the intraperitoneal glucose tolerance and diminish the FIRI. These results indicate that shallot and garlic extracts have a hypoglycemic influence on the fructose-induced insulin resistance animals and aqueous shallot extract is a stronger hypoglycemic agent than the garlic extract.     

Multidisciplinary Canadian consensus recommendations for the management and treatment of hepatocellular carcinoma

Globally, hepatocellular carcinoma (hcc) is the third most common cause of death from cancer, after lung and stomach cancer. The incidence of hcc in Canada is increasing and is expected to continue to increase over the next decade. Given the high mortality rate associated with hcc, steps are required to mitigate the impact of the disease. To address this challenging situation, a panel of 17 hcc experts, representing gastroenterologists, hepatologists, hepatobiliary surgeons, medical oncologists, pathologists, and radiologists from across Canada, convened to provide a framework that, using an evidence-based approach, will assist clinicians in optimizing the management and treatment of hcc. The recommendations, summarized here, were developed based on a rigorous methodology in a pre-specified process that was overseen by the steering committee. Specific topics were identified by the steering committee and delegated to a group of content experts within the expert panel, who then systematically reviewed the literature on that topic and drafted the related content and recommendations. The set of recommendations for each topic were reviewed and assigned a level of evidence and grade according to the levels of evidence set out by the Centre for Evidence-based Medicine, Oxford, United Kingdom. Agreement on the level of evidence for each recommendation was achieved by consensus. Consensus was defined as agreement by a two-thirds majority of the 17 members of the expert panel. Recommendations were subject to iterative review and modification by the expert panel until consensus could be achieved.     

Endoluminal dilation technique to remove "stuck" tunneled hemodialysis catheters

Most tunneled catheters can be easily removed after the retention cuff is dissected. Occasionally, these catheters can become resistant to removal even after application of potentially hazardous forceful traction. In addition, an infected catheter may cause life-threatening septicemia. Several methods have been described for their extraction, some of which may be available only in tertiary-care facilities. The present report describes the successful extraction of five such "stuck" catheters by using a recently described technique of endoluminal dilation. The technique appears safe and straightforward and can be performed in any interventional suite while allowing preservation of venous access.     

High Incidence of Migration with Poor Initial Fixation of the Accolade<Superscript>®</Superscript> Stem

Background  

Numerous cementless femoral stem design variations are in clinical use. Because initial implant instability and micromotion are associated with aseptic loosening of the femoral component, migration analysis provides an early assessment of implant survivorship.     

Spontaneous intrajugular migration of long-term central venous access catheters.

Two patients with long-term central venous access catheters introduced via the right subclavian vein demonstrated catheter migration into the right internal jugular vein several months after satisfactory catheter placement. One patient developed internal jugular vein thrombosis, which was treated with direct infusion of urokinase before catheter removal. In the other patient, the catheter was repositioned by using an intravascular snare loop, which was introduced via the femoral vein. In the first patient, an interim chest radiograph suggested the mechanism by which the catheter had migrated and provided a clue for early detection of catheter migration.     

Peptic ulcer-induced gastroaortic fistula: difficulty in making the diagnosis with selective angiography

We report a patient who had a gastroaortic fistula. This rare, potentially curable cause of torrential upper gastrointestinal hemorrhage is usually secondary to perforation of a gastric ulcer into the distal thoracic aorta. Hiatal hernia and previous gastroesophageal surgery (as in our patient) are important contributing factors in its genesis. It is essential to suspect this condition clinically so that the correct angiographic diagnosis can be made by biplane mid-stream thoracoabdominal aortography.     

Upper gastrointestinal bleeding secondary to an aberrant right subclavian artery-esophageal fistula: a case report and review of the literature.

An aberrant right subclavian artery (ARSA) is a common aortic arch abnormality. A case of a 57-year-old man presenting with melena and hypotension secondary to an ARSA-esophageal fistula is reported. The current report is unique because it is the first reported case of ARSA-esophageal fistula associated with prior esophagectomy and gastric pull-up. A MedLine search was performed for ARSA-esophageal fistula cases, which were then compared with the present case. Because this patient had no vascular conduits, nasogastric or endotracheal tubes, the fistula likely occurred secondary to the previous surgery. This case is unusual because the patient survived the original hemorrhage associated with the ARSA-esophageal fistula. An ARSA-esophageal fistula is a rare, but potentially fatal cause of upper gastrointestinal bleeding. A high index of suspicion is needed to make the diagnosis. This condition should be considered in patients with risk factors combined with hemodynamically significant gastrointestinal bleeding.
