Osteogenic citric acid linked chitosan coating of 3D-printed PLA scaffolds for preventing implant-associated infections.

>25 % of the patients who receive orthopedic implants have been reported with implant-associated osteomyelitis, which can result in inflammation, osteolysis, and aseptic loosening of implants. Current treatment methods doesn't ensure defect healing and prevention from reinfection. Thermoplastic-based 3D-printed scaffolds offer a bioresorbable, biocompatible, and mechanical strong implant system.

Accidental Organophosphate Poisoning in a Toddler: A Case Report.

While accidental poisoning is fairly common in children, the data are sparse when organophosphate (OP) is considered the culprit toxin. Only case reports of such patients from the Southeast Asian Region have been documented, despite it contributing largely to the global burden of organophosphorus poisoning in the adult population. This can be attributed to difficulty in diagnosing children because of varied presentations in the pediatric population and unreliable or unavailable exposure history.

Thrust enhancement and degradation mechanisms due to self-induced vibrations in bio-inspired flying robots.

Bio-inspired flying robots (BIFRs) which fly by flapping their wings experience continuously oscillating aerodynamic forces. These oscillations in the driving force cause vibrations in the motion of the body around the mean trajectory. In other words, a hovering BIFR does not remain fixed in space; instead, it undergoes oscillatory motion in almost all directions around the stationary point.

Anti-snake Venom-Induced Kounis Syndrome: A Unique Case in the Emergency Department.

Kounis syndrome is the concurrence of acute coronary syndromes associated with allergic or hypersensitivity and anaphylactic or anaphylactoid triggers. Although it is not a rare diagnosis, the different presentations and afflictions of all ages, sex, and racial groups make it a diagnostic challenge. Various triggers include food types, environmental exposure, and drugs.

Point of care ultrasound as initial diagnostic tool in acute dyspnea patients in the emergency department of a tertiary care center: diagnostic accuracy study.

Background: Dyspnea is one of the common symptoms patients present to the emergency department (ED). The broad spectrum of differentials often requires laboratory and radiological testing in addition to clinical evaluation, causing unnecessary delay. Point of care ultrasound (PoCUS) has shown promising results in accurately diagnosing patients with dyspnea, thus, becoming a popular tool in ED while saving time and maintaining safety standards.

Marijuana-induced acute myocardial infarction in a young adult male.

A 27-year-old man presented to the emergency department of a tertiary care centre with complaints of acute onset breathing difficulty and retrosternal chest discomfort of 6 hours' duration. On primary survey, he was dyspnoeic with a room air saturation of 85% and a blood pressure of 80/50 mm Hg. A bedside ultrasound revealed an ejection fraction of around 40%, with hypokinesia of interventricular septum, left ventricular apex and anterior wall with bilateral multiple B lines in all lung zones.
