Fusarium species are well-known plant pathogens and food contaminants that have also appeared as one of the most important groups of medically significant fungi. The sequences of the translation elongation factor (TEF)-1α gene have been broadly employed for species detection. A total of 50 strains of Fusarium spp., including environmental, clinical and reference isolates were used for the current study. The primer sets, Fu3f and Fu3r, were used to amplify an ~420-bp DNA fragment of the TEF-1α gene. Double digestion with two restriction enzymes, XhoI and SduI was used for discrimination of the Fusarium species in the TEF-1α gene fragment...

REVIEW
George W Holcomb
This review centers on the thoracoscopic management of esophageal atresia (EA) and distal tracheoesophageal fistula (TEF). The first thoracoscopic repair of EA was performed by Rothenberg and Lobe in Berlin in 1999 just prior to an IPEG meeting. Since that time, the largest report describing the use of thoracoscopy for EA/TEF repair came in 2005 with a multi-national, multi-institutional retrospective review from six institutions around the world. The outcomes reported were quite good and very comparable to large series of open operations that had been previously reported...

There is a dearth of evidence on the safety of the use of antipsychotics during pregnancy. Olanzapine, a pregnancy category C drug, has no unequivocal evidence of harm to the fetus. Against this backdrop, we report the first case of a tracheo-esophageal fistula (TEF) in a newborn following maternal antenatal exposure to olanzapine. A 29-year-old woman with acute psychotic disorder had been treated with olanzapine for the last 7 years. Her first pregnancy, while taking olanzapine, resulted in a miscarriage at 4 months' gestation, following which she discontinued olanzapine...

Background The short- and long-term surgical results in patients with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have been described in depth from a physician's perspective. Contrarily, the perception and coping strategies of affected patients and their parents have rarely been reported. The aim of this study was to generate data on this matter. Patients and Methods A total of 154 patients who had operative reconstruction for EA between 1971 and 2012 were evaluated for demographic data, surgical technique, affection of daily life, and coping strategies...

Background Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) represents the most common developmental malformation of the upper digestive tract. It is classified into six subtypes according to the classification of Vogt, depending on anatomical variation of this malformation. Around 50% of the patients with EA/TEF present additional anomalies, which often influence, next to the EA/TEF subtype, the overall prognosis of EA/TEF newborns. Here, we investigated the association of the different EA/TEF subtypes with co-occurring congenital anomalies in EA/TEF patients and demonstrate their implications for postnatal diagnostic workup...

BACKGROUND: Malignancy is the most common etiology of acquired fistulae between the tracheobronchial tree and esophagus. The majority are due to either primary bronchial or esophageal carcinoma, and are typically observed in adult population. The occurrence of tracheoesophageal fistula (TEF) in patients with Hodgkin lymphoma is a rare phenomenon. OBSERVATION: We report a rare case of Hodgkin lymphoma with TEF in a 10-year-old girl at presentation. She also developed pulmonary tuberculosis later during the follow up...

INTRODUCTION: Esophagrams are routinely performed following repair of esophageal atresia (EA) with or without tracheoesophageal fistula (TEF); however, its utility has not been validated. METHODS: EA/TEF repair performed from 2003 to 2014 at a single pediatric hospital and from 2004 to 2014 in the Pediatric Health Information System (PHIS) database were retrospectively reviewed to determine utility of esophagrams. RESULTS: Esophagram was performed in 99% of patients at our institution (N = 105)...

The caterpillar fungus Ophiocordyceps sinensis (previously called Cordyceps sinensis) has been used for centuries in Asia as a tonic to improve health and longevity. Recent studies show that O. sinensis produces a wide range of biological effects on cells, laboratory animals and humans, including anti-fatigue, anti-infection, anti-inflammatory, antioxidant, and anti-tumor activities. In view of the rarity of O. sinensis fruiting bodies in nature, cultivation of its anamorph mycelium represents a useful alternative for large-scale production...

BACKGROUND: Motility disturbances of the esophagus and gastroesophageal reflux disease (GERD) are observed frequently in children after repair of congenital esophageal atresia with distal tracheoesophageal fistula (EA/TEF). Recently, in many pediatric surgical centers, thoracoscopic repair was introduced, which theoretically would change the postoperative course. OBJECTIVES: The goal of the study was to assess physical development, disease symptoms, and GERD symptom frequency in children who underwent thoracoscopic surgery of congenital EA/TEF...

Metabolism of non-glucose carbon sources is often highly regulated at the transcriptional and post-translational levels. This level of regulation is lacking in Saccharomyces cerevisiae strains engineered to metabolize xylose. To better control transcription in S. cerevisiae, the xylose-dependent, DNA-binding repressor (XylR) from Caulobacter crescentus was used to block transcription from synthetic promoters based on the constitutive Ashbya gossypii TEF promoter. The new hybrid promoters were repressed in the absence of xylose and showed up to a 25-fold increase in the presence of xylose...

BACKGROUND/PURPOSE: Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a rare congenital anomaly lacking contemporary data detailing patient demographics, medical/surgical management and outcomes. Substantial variation in the care of infants with EA/TEF may affect both short- and long-term outcomes. The purpose of this study was to characterize the demographics, management strategies and outcomes in a contemporary multi-institutional cohort of infants diagnosed with EA/TEF to identify potential areas for standardization of care...

PURPOSE OF REVIEW: To highlight the results of the ongoing research on the mechanisms of liver-induced tolerance focusing on results from the last year. RECENT FINDINGS: The liver is exposed to a massive antigenic burden of dietary and commensal products from the gastrointestinal tract via portal vein, most of which are necessary for survival. To prevent the immune system from destroying these foreign yet beneficial elements, the liver has developed unique mechanisms to suppress immune responses...

BACKGROUND: To date almost 200 genes were found to be associated with major depressive disorder (MDD) or suicide attempts (SA), but very few genes were reported for their molecular mechanisms. This study aimed to find out whether there were common or rare variants in three candidate genes altering the risk for MDD and SA in Chinese. METHODS: Three candidate genes (HOMER1, SLC6A4 and TEF) were chosen for resequencing analysis and association studies as they were reported to be involved in the etiology of MDD and SA...

BACKGROUND: Polyhydroxybutyrates (PHBs) are macromolecules synthesized by bacteria. They are inclusion bodies accumulated as reserve materials when the bacteria grow under different stress conditions. Because of their fast degradability under natural environmental conditions, PHBs are selected as alternatives for production of biodegradable plastics. The aim of this work was to isolate potential PHB producing bacteria, evaluate PHB production using agro-residues as carbon sources. RESULT: Among fifty bacterial strains isolated from different localities, ten PHB accumulating strains were selected and compared for their ability to accumulate PHB granules inside their cells...

Aortopulmonary window is a rare form of congenital heart disease that requires significant anesthetic considerations. Cardiac involvement is a well-known comorbidity identified in patients with tracheoesophageal fistula (TEF). Identification of coexisting lesions, specifically congenital heart disease, is crucial before undergoing repair of a TEF. Understanding the complex physiology and expected changes occurring during the anesthetic and surgical intervention for correction of TEF with a significant unrepaired shunting defect is crucial to prevent hemodynamic instability...

Recently, mycetoma was added to the World Health Organization's list of neglected tropical disease priorities. Fusarium as a genus has been reported to cause eumycetoma, but little is known about the species involved in this infection and their identification. In this study, molecular tools were applied to identify Fusarium agents from human eumycetoma cases. The partial translation elongation factor 1-alpha (TEF-1α) gene was used as diagnostic parameter. Two additional cases of eumycetoma, due to F. keratoplasticum and F...
