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...
This study was designed to evaluate the clinical and radiographic outcomes of patients with nutcracker syndrome (NCS) who were treated with three-dimensional printing (3DP) extravascular titanium stents (EVTSs). The 3DP EVTS was expected to release the hypertension of the left renal vein (LRV) produced by its compression between the superior mesenteric artery (SMA) and the aorta without causing any complications. METHOD: The pre-operative kidney model of each patient was printed out to enable surgical planning. After that, the EVTS was designed based on the LRV's primitive physiologic structure using computer-aided de...
ConclusionCEUS can be used as a supplementary method to diagnose scar pregnancy and evaluate the treatment efficacy, especially in cases with ambiguous results by TVS.
Publication date: Available online 8 June 2019Source: SexologiesAuthor(s): M. OhayonSummaryImprovements in the prognosis for HIV infection and the impact of biomedical strategies for the prevention of transmission have created very specific situations for men who live with HIV within the homosexual minorities. Originally focused on their duty in preventing transmission, the issue at stake gradually moved towards one of power, with the HIV-infected person, the hero/martyr of the 1980s and 1990s, becoming the hero who has vanquished the fear of Aids. Undetectable viral load, the standard of current treatment, makes the indiv...
We describe a 63-year-old woman with signs and symptoms of intracranial hypertension. Brain MRI revealed hydrocephalus. Venous Doppler ultrasound showed external compression of the omohyoid muscles on the internal jugular veins. During jugular vein decompression, intracranial pressure dropped from 18 to 6 mmHg. Patient is asymptomatic at 2-year follow-up, with decreased brain ventricles. These findings could represent a novel form of high-pressure hydrocephalus that can be successfully treated without a CSF shunt. We called this syndrome JEDI (jugular entrapment dilated ventricles intracranial hype rtension).
This study aimed to evaluate the antimicrobial activities of EOs of cinnamon (CEO), rosemary (REO), and oregano (OEO) EOs encapsulated in oil-in-water nanoemulsions prepared using high-frequency ultrasound and applied onto fresh celery inoculated with Escherichia coli and Listeria monocytogenes. The characteristics of CEO, REO, and OEO nanoemulsions were: pH, 4.69–5.84; viscosity, 1.844–1993 mPa s; density, 1.004–1.018 g/cm3; color parameters, Lh > 80 (ah: negative and bh: positive); particle size (D50) 226–546 nm; phase separation, 80%. Compared with the nonencapsulated EOs, EOs nano...
Conclusion A recurrent perineal hernia can be prevented by a solid fixation of the mesh using the technique of a glued mesh repair. This technique shows to be easy, fast and without recurrence. PMID: 31204903 [PubMed - as supplied by publisher]
CONCLUSION: A rare case of neurofibromatosis associated GIST with multifocal localization was successfully treated by cephalic duodenopancreatectomy. KEY WORDS: Neurofibromatosis type 1 (NF1), Retroperitoneal Gastrointestinal Stromal Tumor (GIST). PMID: 31203268 [PubMed - in process]
CONCLUSIONS: As with all cases of severe asthma, the assessment of comorbidities must be systematic in the presence of an occupational asthma which persists after the cessation of the occupational exposure. The management of these comorbidities can lead to an improvement in asthma control and severity. PMID: 31204233 [PubMed - as supplied by publisher]
CONCLUSIONS: CPET may greatly facilitate the diagnosis of unexplained dyspnoea. More than 50% of the dyspnoea cases examined here were due to deconditioning or hyperventilation syndrome and would benefit from a simple pulmonary rehabilitation program.

CONCLUSION: Rarely, emphysematous bullae resolve following infections. Further studies of the mechanisms involved in these natural regressions may be of interest in the development of new therapeutics. PMID: 31202604 [PubMed - as supplied by publisher]
