The Hidden Culprit: A Computed Tomography Diagnosis of H-Type Tracheoesophageal Fistula in an Adult Revealed After Two Decades of Pulmonary Infections.
Cureus
October 2024
Radiology, Souss Massa University Hospital, Agadir, MAR.
Article Synopsis
- A 41-year-old male with a history of cardiopathy and respiratory issues presented with severe symptoms related to heart failure, including significant dyspnea and edema after years of recurrent infections.
- Diagnostic tests revealed multiple complications including dilation of cardiac chambers and a rare congenital condition known as H-type tracheoesophageal fistula (TEF), which contributed to his respiratory problems.
- The patient was admitted to the ICU for intensive management, including treatment for pulmonary artery hypertension and preparation for surgical intervention to repair the fistula.
Expression of c-jun/c-fos mRNA Indicates Persistent Myocardial Stretch During Asphyxia-Induced Cardiac Arrest.

Right ventricular dysfunction is a key clinical issue for the viability of donation-after-circulatory-death (DCD) heart transplantation. DCD hearts with volume overload have the potential to exhibit aggravated right ventricular dysfunction following heart transplantation. The c-jun/c-fos mRNAs are genes that immediately respond to myocardial cell stretch.

J Equine Vet Sci
December 2024
Faculty of Veterinary Science, University of Pretoria, M35, Onderstepoort, Pretoria 0110, South Africa.
Article Synopsis
- A mare was admitted with significant neck swelling, lethargy, and loss of appetite, leading to the discovery of serious injuries via radiography and endoscopy, including emphysema and lacerations.
- Treatment involved antimicrobials, fluids, and surgeries like temporary tracheostomy and esophagostomy, addressing issues such as deep cervical infection and esophageal impaction.
- After a recovery period with ongoing management, the mare successfully returned to competition after being discharged 51 days later.
Venom-induced myocarditis: An unusual case attributable to Vipera aspis bite.
Toxicon
November 2024
Division of Cardiology, SS Trinita' Borgomanero Hospital, ASL NO, Novara, Italy.
Article Synopsis
- Venomous snake bites, like those from the Vipera aspis, can lead to serious medical emergencies, including rare cardiovascular issues, and require immediate treatment.
- A case study of a 33-year-old reptile zoo keeper shows severe complications after a viper bite, including angioedema, severe thrombocytopenia, anemia, and compartment syndrome, necessitating surgical intervention and supportive transfusions.
- The patient also experienced cardiac issues such as low blood pressure and myocarditis, confirmed by echocardiography and MRI, highlighting the need for early identification and treatment of uncommon complications from snake bites with antivenom.
Functioning of unidirectional ventilation in flying hawkmoths evaluated by pressure and oxygen measurements and X-ray video and tomography.
J Exp Biol
September 2024
European Synchrotron Radiation Facility, 71 Avenue des Martyrs, F-38043 Grenoble, France.
Article Synopsis
- Flying sphingids utilize a unique ventilation system where air enters through the front thoracic spiracles and exits through the back thoracic spiracles, which has been previously studied using CO2 emissions and tracheal pressure changes.
- In this study, researchers measured tracheal pressure and oxygen levels, as well as monitored wing movements, to understand how these insects' abdominal muscles and flight muscles work together to create airflow.
- The metathoracic air sacs are crucial for ventilation, showing a rise and fall in oxygen levels during flight, indicating that as flight muscles contract, they effectively create suction to expand these air sacs, contributing to efficient unidirectional airflow.
