What Are the Types of Tracheoesophageal Fistulas?
Discussion Respiratory problems in infants can caused by many things including any type of obstruction from the nose to lung. Neonates and infants are particularly susceptible to changes in the size of the airway because of the physics of airflow resistance. Important reminders about infant airways: Resistance = 1/radius4 (Poiseuille’s equation) therefore even a 1 mm decrease in the airway circumferences increases the airflow resistance x16. Increased airflow causes less pressure along the walls, which can lead to collapse of the walls (Bernoulli’s and Venturi effects). Neonates have smaller lungs relative to the rest of their body therefore they have less pulmonary reserve. Neonates have higher oxygen consumption rates (about 50% more) than older children and adults. Neonates are preferential nose breathers. Neonates have immature regulation of vital functions and when stressed may do the opposite of what is expected. For example, they may become apneic with respiratory distress instead of increasing their respiratory rate. Therefore anything that changes the airflow dynamics of the infant airway can cause dramatic effects for a neonate. Health care personnel need to be aware of subtle changes and may need to respond quickly to the infant’s respiratory status, even while trying to determine the cause of the problem. Learning Point Esophageal atresia (EA) with tracheoesophageal fistula are anomalies in the continuity of the esophagus with or without trac...
CONCLUSIONS For patients with type II and III CSP, hysteroscopy and laparoscopy surgery and reversible ligation of the uterine artery achieved better clinical outcomes than hysteroscopy or curettage with respect to postoperative recovery. This could be suitable for patients with CSP and desire for fertility. PMID: 32595205 [PubMed - in process]
CONCLUSIONS Coexpression analysis of EZH2 identified its role in the cell cycle, mitosis, and DNA repair. The molecular mechanisms involved in EZH2 gene expression in the cell response to DNA damage requires further study to determine whether EZH2 is a potential human cancer biomarker.

CONCLUSION: Esophageal dilatation is effective for the management of children with esophageal stricture; however, repeated dilatation is frequent, especially in patients with corrosive strictures. Complications are not common, and open surgery is not frequently required. PMID: 32601640 [PubMed - in process]
CONCLUSION: Despite existing evidence and a consensus on its superiority over the landmark technique, USG-CVC placement has not been adopted by a small proportion of EPs into clinical practice. Formal training, education, and institutional provision of permanent onsite US machines may address any barriers. PMID: 32601636 [PubMed - in process]

CONCLUSIONS: Pelvic venography is a not mandatory component of the examination of women with pelvic and vulvar varicose veins without varicose veins of the lower extremities, who do not have symptoms of the PCS and valvular incompetence of the gonadal veins according to the DUS.

The authors summarize the most important anatomic and physiologic substrates of Fontan circulation. Common anatomic substrates include hypoplastic left heart syndrome, tricuspid atresia, double inlet left ventricle, and unbalanced atrioventricular septal defects. After the Fontan operation exercise capacity is limited and the key hemodynamic drivers is limited preload due to a relatively fixed pulmonary vascular resistance. The authors provide contemporary data on survival, morbidity, and need for reintervention. Operative morality is now expected to be less than 1% and 30 year survival approximately 89%. The authors delin...
