Tracheo-esophageal fistulae (TEF) due to trauma are rare. We report a case of a delayed TEF caused by a shrapnel from a blast. A 25-year-old male was admitted to the hospital after sustaining a blast injury. A contrast CT scan of the chest and neck revealed the presence of metallic shrapnel in close proximity to the tracheo-esophageal groove at the level of the thoracic inlet. Bronchoscopy revealed 0.5 cm tear in the membranous trachea while esophagoscopy and contrast swallow were normal. Coughs after starting fluid intake triggered a repeat endoscopy that showed a large TEF at 22 cm from the incisors. He underwent surgical repair through a collar incision and limited sternotomy. The TEF extended for 2 cm. The esophagus was repaired in two layers, the membranous trachea was sutured primarily, and an interposition strap muscle flap was placed. A contrast swallow on postoperative day 7 revealed the presence of a small leak into the trachea that was treated conservatively. Traumatic TEF are rare and should be suspected in patients with injuries to proximal structures. Delay in diagnosis and appropriate management can conceivably lead to death.

Rhizobium etli is a nitrogen-fixing bacterium that encodes two l-asparaginases. The structure of the inducible R. etli asparaginase ReAV has been recently determined to reveal a protein with no similarity to known enzymes with l-asparaginase activity, but showing a curious resemblance to glutaminases and β-lactamases.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.

Background: Anticoagulants increase the risk of cardiac tamponade in patients with pericardial effusion (PE). Therefore, inappropriate administration of them in the presence of PE can lead to a catastrophic outcome. This study presents a patient with a provisional misdiagnosis of venous thromboembolism (VTE).

Introduction: The coexistence of gallbladder (LSG) and adenomyomatosis (ADM) is extremely uncommon presenting a novel clinical dilemma that has not been previously documented. LSG refers to a anomaly where the gallbladder is situated to the left of the round ligament deviating from its usual position. This anomaly is rare, with reported occurrences ranging between 0.

Surface relief grating formation in photo-responsive azo polymers under irradiation is a long-ago-found phenomenon, but all the factors governing its efficiency are still not fully recognized. Here, we report on the enormous impact of the polymer thickness on the possibility of fabrication of extremely high-amplitude surface deformations. We performed prolonged holographic recordings on the layers of the same azobenzene poly(ether imide), which had substantially different optical transmittances at the recording wavelength and revealed that the depths of the inscribed relief structures increased with the polymer thickness from a nondetectable value up to almost 2 µm, unaffected by the presence of a polymer-glass substrate interface in either sample.
