The Salmonella effector SseJ disrupts microtubule dynamics when ectopically expressed in Normal Rat Kidney cells

Salmonella effector protein SseJ is secreted by Salmonella into the host cell cytoplasm where it can then modify host cell processes. Whilst host cell small GTPase RhoA has previously been shown to activate the acyl-transferase activity of SseJ we show here an un-described effect of SseJ protein production upon microtubule dynamism. SseJ prevents microtubule collapse and this is independent of SseJ's acyl-transferase activity. We speculate that the effects of SseJ on microtubules would be mediated via its known interactions with the small GTPases of the Rho family

Epidural lipomatosis and congenital small spinal canal in spinal anaesthesia: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Complications after lumbar anaesthesia and epidural blood patch have been described in patients with congenital small spinal canal and increased epidural fat or epidural lipomatosis. These conditions, whether occurring separately or in combination, require magnetic resonance imaging for diagnosis and grading, but their clinical significance is still unclear.</p> <p>Case presentation</p> <p>A 35-year-old Caucasian woman who was undergoing a Caesarean section developed a longstanding L4-L5 unilateral neuropathy after the administration of spinal anaesthesia. There were several attempts to correctly position the needle, one of which resulted in paraesthesia. A magnetic resonance image revealed that the patient's bony spinal canal was congenitally small and had excess epidural fat. The cross-sectional area of the dural sac was then reduced, which left practically no free cerebrospinal fluid space.</p> <p>Conclusion</p> <p>The combination of epidural lipomatosis of varying degrees and congenital small spinal canal has not been previously discussed with spinal anaesthesia. Due to the low cerebrospinal fluid content of the small dural sac, the cauda equina becomes a firm system with a very limited possibility for the nerve roots to move away from the puncture needle when it is inserted into the dural sac. This constitutes risks of technical difficulties and neuropathies with spinal anaesthesia.</p

“Flag Excision and Flap” Procedure: a Novel Modification for Off-Midline Closure After Pilonidal Sinus Excision

Pilonidal sinus surgery has evolved with the novel flap techniques, and off-midline closure became a preferred surgical procedure due to shorter recovery time and low recurrence rates. To obtain a better off-midline closure without maceration and a possible wound problem, we modified a novel excision technique. We aimed to present this novel flag modification of rhomboid excision and flap reconstruction experience. From December 2007 to June 2009, 100 patients were treated with flag excision and flap reconstruction under regional anesthesia and followed with a mean of 42 (range 35–55) months. Competent closure results were obtained successfully in all patients without an overlap between incision line and midline. None of the patients had seroma. Two patients (2 %) had partial wound detachment superiorly. None of the patients had recurrence during follow-up. The flag excision and flap reconstruction procedure is an effective and comfortable technique both for the surgeon and the patient with a quick healing period and low complication rates without maceration
