Bleeding from ectopic varices is rare and accounts for only 1% and 5% of all variceal bleeding. However, once the bleeding starts, it becomes difficult to control and is sometimes fatal. We faced a 65-year-old man with ruptured duodenal varices and injected N-butyl-2-cyanoacrylate into the spurting duodenal varices. As a result, oozing was successfully controlled. Subsequently, the patient rema...

A 65−year−old man, who had been diag− nosed 20 years previously with noncir− rhotic portal hypertension due to bilhar− ziasis, was admitted with gastric variceal bleeding. He had undergone esophageal variceal eradication in the past. The vari− ces were injected with cyanoacrylate di− luted with Lipiodol (1.5 ml/2.1ml). After several hours, the patient complained of chest pain and an inability t...

Open and distance learning at the higher education level is a central issue of today, and seems to be a strong contribution towards the democratisation of access to learning. The advanced information and communication technologies (ICT) together with several applications offer new perspectives, such as the e-learning, networked learning and other ICT enabled environments. However, these new app...

Electronic absorption and resonance Raman spectral studies of benzoylruthenocene (BRc) and 1,1'-dibenzoylruthenocene (DRc) indicate that the low-energy electronic excited states of these 4d(6) metallocenes possess metal-to-ligand charge transfer (MLCT) character. While this MLCT contribution should weaken the metal-ring bonding in the excited state, neither compound is photosensitive in nonhalo...

uterine arteriovenous malformations (avms) are relatively rare disorders that can cause life-threatening vaginal bleeding. we describe three childbearing-age females, who had abdominal pain and heavy vaginal bleeding, and were diagnosed as uterine avm by color doppler and angiography. the patients received successful superselective transarterial embolization (tae) with n-butyl cyanoacrylate (nb...

In the present study we assessed the forms and functions of prelinguistic communicative behaviors for 120 children and adults with Rett syndrome using the Inventory of Potential Communicative Acts (IPCA) (Sigafoos et al. Communication Disorders Quarterly 21:77-86, 2000a). Informants completed the IPCA and the results were analysed to provide a systematic inventory and objective description of t...

The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, performing a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identi...

PURPOSE To evaluate the clinical efficacy and histopathological tolerance of 2-octyl cyanoacrylate versus conventional suture materials for eyelid wound closure in rabbits. METHODS We performed an experimental study on 16 eyes of eight New Zealand albino rabbits. Eyelid incisions of 15 mm were done 4mm from the upper eyelid margin in both eyes. The eyes of the rabbits were divided into two gr...

Background: Varicose veins are a common vascular disorder that can cause discomfort and aesthetic concerns. Cyanoacrylate glue foam sclerotherapy treatment modalities used to prevent recurrence of varicose veins, but their comparative effectiveness is not well established. Objective: This research compared the cyanoacrylate in preventing vein recurrence. Methods: A randomized controlled trial w...
