How to cite: Gharpure V. Esophageal atresia with/without tracheoesophageal fistula. QUESTIONS 1. What clinical and sonographic features should make one suspect esophageal atresia in a pregnancy? 2. What is the quickest method of diagnosing esophageal atresia, with or without tracheo-esophageal fistula (TEF)? 3. What management principles should be followed in a newborn with esophageal atresia ±...

Acquired tracheo-oesophageal fistula (TEF) after tracheostomy is a life threatening complication and can occur in about 1% of cases of tracheostomy. Percutaneous tracheostomy was performed in intensive care unit on a 40 years male patient for long-term mechanical ventilation. Subsequently patient developed TEF as the complication of tracheostomy. He was initially managed with endoscopically ins...

The redox chemistry of the homoleptic iron prismane cluster [{Cp*Fe}3(?3,?4:4:4-As6)] (A, Cp*=C5Me5) is investigated both electrochemically and synthetically. While its first oxidation leads to diamagnetic species [{Cp*Fe}3(?3,?4:4:4-As6)][X] ([1][TEF], [1][FAl], [TEF]?=[Al{OC(CF3)3}4]?, [FAl]?=[FAl{O(1-C6F5)C6F10}3]?), second yields paramagnetic [{Cp*Fe}3(?3,?4:4:4-As6)][TEF]2 ([2][TEF]2). red...

The thermic effect of food (TEF) is an important physiological determinant of total daily energy expenditure (EE) and energy balance. TEF is believed to be mediated in part by sympathetic nervous system activation and consequent beta-adrenergic receptor (beta-AR) stimulation of metabolism. TEF is greater in habitually exercising than in sedentary adults, despite similar postprandial sympathetic...

Determining seafood geographic origin is critical for controlling its quality and safeguarding the interest of consumers. Here, we use trace element fingerprinting (TEF) of bivalve shells to discriminate the geographic origin of specimens. Barium (Ba), manganese (Mn), magnesium (Mg), strontium (Sr) and lead (Pb) were quantified in cockle shells (Cerastoderma edule) captured with two fishing met...

RATIONALE Congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) ininfants have been treated well with surgery. Approximately 10% of children displayed recurrent fistula. In the present case, we reported recurrent TEF in an adolescent as a complication of EA/TEF in infancy. PATIENT CONCERNS An infant was diagnosed with gross type C congenital EA and TEF and subsequentlyunderwe...

BACKGROUND/AIMS Patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) often suffer chronic respiratory tract disease. We previously reported that primary lung maldevelopment caused by deficient branching of embryonal airways in experimental EA-TEF was induced by Adriamycin. In this study, we investigated the Vascular endothelial growth factor (VEGF) pathway in the developing...

PURPOSE Thoracoscopic esophageal atresia (EA)/tracheoesophageal fistula (TEF) repair is technically challenging. We have previously reported our experiences with a high-fidelity hybrid model for simulation-based educational instruction in thoracoscopic EA/TEF, including the high cost of the tissue for these models. The purposes of this study were (1) to create a low-cost synthetic tissue EA/TEF...

Phosphatidylcholine biosynthesis via the CDP-choline pathway is primarily regulated by CTP:phosphocholine cytidylyltransferase (CT). Transcriptional enhancer factor-4 (TEF-4) enhances the transcription of CTalpha in COS-7 cells by interactions with the basal transcription machinery (Sugimoto, H., Bakovic, M., Yamashita, S., and Vance, D.E. (2001) J. Biol. Chem. 276,12338-12344). To identify the...

OEHHA is proposing to replace the Toxicity Equivalency Factors (TEF), which were developed by the World Health Organization (WHO) in 1997, with the more recent TEF values developed by the WHO in 2005. We agree with and support this revision. As noted correctly by OEHHA, the TEF methodology has evolved and improved over the years as additional toxicological data became available. The adoption of...
