Successful intra-arterial thrombolytic therapy for a right middle cerebral artery stroke in a 2-year-old supported by a ventricular assist device

Embolic stroke is a common complication in patients on ventricular assist devices in both adults and children. The reported incidence of strokes in children supported by VAD's varies from 7 to 38%. The rapid increase in recent years in the availability of both adult and pediatric VADs will likely add to the overall prevalence of strokes in patients being bridged to heart transplant. Strokes in this population can be lethal as they frequently necessitate withdrawal of the extracorporeal device support and withdrawal from the organ transplant waiting list. We present a case of a fully anti-coagulated 29-month-old supported on a Berlin EXCOR LVAD (Berlin, Germany) with embolic stroke which was treated successfully with direct thrombolysis with recombinant tissue plasminogen activator. This is the first report which uses intra-arterial thrombolytics while on a ventricular assist device in a pediatric patient.     

Immunosuppression in renal transplantation: Long-term clinical trial of a double versus triple therapy regimen

Summary: Sixty-nine renal allograft recipients were randomized to two immunosuppressive regimens: 35 patients received cyclosporine A and prednisolone (PC) while 34 patients received low dose cyclosporine A, prednisolone and short term azathioprine (PCA). the data of 66 patients (34 in PC and 32 in PCA groups) were analysed. the median follow-up periods were 62 months for the PC group and 60 months for the PCA group. There was no difference in graft survival between the two groups but five patients died in the PC group compared to none in the PCA group (graft survival: 88 vs 90% at 1 year and 82 vs 82% at 5 years, P = not significant at any time point; patient survival: 90 vs 100% at 1 year and 88 vs 100% at 5 years, P = 0.05 at 5 years). There was a trend for patients in the PCA group to develop earlier and more frequent rejections (not significant; P = 0.106 and P = 0.062, respectively). There were also more episodes of acute cyclosporine A nephrotoxicity and cytomegalovirus (CMV) infection in the PC group. the mean serum creatinine at 5 years was significantly higher in the PCA group when compared to the PC group (179.8 ± 76.5 μmol/L vs 154.7 ± 41.0 μmol/L; P =0.05). We found that both therapeutic regimens were effective in preventing renal allograft rejections. However, double therapy was associated with higher patient mortality secondary to infection. Patients on triple therapy, on the other hand, were more prone to develop rejections in the early post-transplant period and were associated with less favourable renal function in the long run.     

Percutaneous cholecystostomy: an alternative to surgical cholecystostomy for acute cholecystitis?

Emergency percutaneous cholecystostomy was successfully performed in 39 of 40 attempted procedures in 37 hospitalized patients with possible acute cholecystitis. All cholecystostomies were performed with ultrasound guidance and preferentially with the transhepatic route, and all but four were performed at the patient's bedside. The patients had been hospitalized an average of 27 days before the procedure. Twenty-two of the 37 patients (59%) eventually died during hospitalization because of other medical or surgical problems. Only minor complications related to percutaneous cholecystostomy placement occurred in this series: catheter dislodgment without sequelae (n = 2) and significant abdominal pain (n = 2). Technical problems included guide-wire buckling during catheter insertion (n = 1) and failed attempted cholecystostomy (n = 1). Percutaneous cholecystostomy is a safe alternative to surgical cholecystostomy in the treatment of patients suspected of having acute cholecystitis.     

The influence of in-pregnancy smoking cessation programmes on partner quitting and women's social support mobilization: a randomized controlled trial [ISRCTN89131885]

Background  

Smoking cessation interventions in pregnancy could influence a woman's social behaviour and her partner's smoking behaviour, but this has not been examined in any published randomized trials.
