BACKGROUND This trial was carried out to assess the value of propranolol in the prevention of recurrent variceal bleeding when combined with longterm endoscopic sclerotherapy. PATIENTS AND METHODS Two hundred patients (161 male, 39 female, age range 20-68 years) with portal hypertension resulting mainly from schistosomal periportal fibrosis or posthepatitic cirrhosis presenting with their fir...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

Patients with cirrhosis of the liver can develop gastric or gastroesophageal varices, which can bleed and become life threatening Gastric varices pose unique management challenges, as endoscopic therapies are limited Balloon-occluded retrograde transvenous obliteration (BRTO) is a treatment option for gastric varice at high risk of bleeding The BRTO is recommended for patients with gastrorenal ...

Cerebral arteriovenous malformations (AVMs) are rare vascular lesions detected at an annual incidence of ≈1 in 100 000. The natural history of unruptured AVMs is more benign than ruptured ones, primarily because of their lower hemorrhage risk. The only currently available strategy for AVM management that provides durable relief from the risk of hemorrhage is complete obliteration of the nidus. ...

PURPOSE The purpose of this retrospective study was to compare the success rates of formocresol pulpotomy in primary molars restored with stainless steel crowns (SSC) to those restored with amalgam (AM). METHODS Radiographs of pulpotomized primary molars restored with SSC or AM in the principal author's pediatric dentist practice were evaluated and defined as a "failure" when one or more of t...

OBJECTIVE This study investigates the safety and efficacy of a multimodality approach combining staged endovascular embolizations with subsequent SRS for the management of larger AVMs. METHODS Ninety-five patients with larger AVMs were treated with staged endovascular embolization followed by SRS between 1996 and 2011. RESULTS The median volume of AVM in this series was 28 cm(3) and 47 pati...

OBJECTIVE To determine the efficacy of frontal sinus drillout surgery for the treatment of chronic frontal sinusitis. DESIGN Retrospective case-control study. Mean +/- SD follow-up was 4.1 +/- 1.53 years (range, 1.4-6.9 years). SETTING Academic medical center. PATIENTS One hundred consecutive patients with chronic sinusitis who underwent frontal sinus drillout surgery. Indications were fa...

INTRODUCTION Long-term outcome of patients after band ligation have been poorly defined. Therefore, we conducted a long-term follow-up study to delineate the outcome of ligation in patients with portal hypertension in the Hassan II university hospital, Fes, Morocco. METHODS Over 118 months patients treated by endoscopic variceal ligation were received regular follow- up and detailed clinical ...

Dual microcatheter retrograde transvenous obliteration (DMRTO) of gastric varices enables dual microcatheters to be advanced to the gastric varices themselves or to a site adjacent to the varices. The sclerosing agent is infused through the first microcatheter following coil embolization of the outflow vessels through the second microcatheter, which is placed several centimeters back from the v...

Stereotactic radiosurgery for intracranial arteriovenous malformations (AVMs) has been performed since the 1970s. When an AVM is treated with radiosurgery, radiation injury to the vascular endothelium induces the proliferation of smooth muscle cells and the elaboration of extracellular collagen, which leads to progressive stenosis and obliteration of the AVM nidus. Obliteration after AVM radios...
