BACKGROUND The predilection site of non-occlusive mesenteric ischemia is the right-sided colon. Surgical exploration followed by segmental bowel resection and primary anastomosis or ileostomy is recommended, if vascular interventions are not feasible and conservative treatment fails. We assessed the outcome of patients in this life-threatening condition. METHODS From a prospective database 58...

A 44-year-old woman underwent gastric bypass surgery in 2004. One year later, she began to complain of intermittent melena associated with nausea and right upper quadrant (RUQ) pain, which required 1 to 2 units of packed red blood cell transfusions per year. In July 2007, she presented to the emergency department with 2 episodes of bright red blood per rectum associated with syncope. Upper endo...

For most warfarin indications, the target maintenance international normalised ratio (INR) is 2-3. Risk factors for bleeding complications with warfarin use include age, history of past bleeding and specific comorbid conditions. To reverse the effects of warfarin, vitamin K(1) can be given. Immediate reversal is achieved with a prothrombin complex concentrate (PCC) and fresh frozen plasma (FFP)...

laseror microdrill-assisted technique may enable better outcomes in terms of intraand post-operative complications as well as of hearing gain as compared with classical stapedotomy technique. Materials and Methods: Eighty-two subjects undergoing primary stapes surgery for otosclerosis were enrolled for this study as having a least pure tone average (PTA) air-bone gap (ABG) of 35 dB. Patients we...

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...

Situs inversus totalis is a rare condition, which presents difficulties in diagnosis and treatment of gallstones due to the reversal location of abdominal organs. In this article we present 2 cases of women in age of 51 and 55 years with situs inversus totalis and gallstones. There are described the clinical and imaging features, also the laparoscopic surgery with the difficulties encountered b...

Atrial tachycardias are common after open heart surgery. Most commonly these are macro-reentrant including cavotricuspid isthmus dependent atrial flutter, incisional right atrial flutter and left atrial flutter. Focal atrial tachycardias occur less frequently. The specific type of atrial tachycardia highly depends on the type of surgical incision. Catheter ablation can be very effective, howeve...

REVERSING warfarin-induced anticoagulation quickly and effectively can be challenging in medically compromised patients presenting for emergency surgery. Anticoagulation reversal poses a delicate balance between increasing the risk of clotting and decreasing the risk of intraoperative blood loss. Furthermore, variable individual responses and warfarin’s adverse effect profile render particular ...

The postoperative retention and reversal of go, no-go avoidance reflex differentiation with symmetrical and asymmetrical reinforcement were studied in dogs with prefrontal lesions and unoperated controls. The general pattern of the influence of such experimental variables as type of differentiation task an,d quality and arrangement of conditioned stimuli' was similar to that oberved preoperativ...
