Electrocution is a leading cause of unnatural deaths, especially in industrial and developing regions like India. In a recent case, an individual was brought in for autopsy following an apparent accidental electrocution. Strikingly, the postmortem examination revealed no typical entry or exit wounds associated with electric shocks. The body exhibited rigor mortis and a unique sign: reddish froth draining from the nasal cavities. Internal examination unveiled distinctive findings. Multiple tiny hemorrhages were observed over the heart's left ventricle, while the heart's blood vessels and valves remained unobstructed...

PURPOSE: To compare the functional and esthetic outcomes of dorsal preservation rhinoplasty (DPR) and conventional dorsal hump reduction (DHR) in primary rhinoplasty using patient-reported outcome measures (PROMs) and cone beam computed tomography (CBCT). METHODS: In our randomized prospective double-blinded clinical trial, 50 patients had dorsal nasal hump surgery between October 2021 and November 2022 in our tertiary referral center. All surgeries were done by the same surgeon...

PURPOSE: To objectively evaluate the effect of maxillary advancement on speech and VPI using video-fluoroscopy (VFS), direct nasoendoscopy, and speech evaluation and subjectively assess patients and their peer's perception regarding their speech outcome. MATERIALS AND METHODS: 27 cleft patients who underwent Lefort 1 maxillary advancement were divided into 2 groups- Group A with 4-7 mm of advancement and Group B with 8-13 mm advancement. VFS in lateral view, nasoendoscopy, and speech recordings were performed pre and 6 months postoperatively...

The disconnected (disco)-interacting protein 2 (DIP2) gene was first identified in D. melanogaster and contains a DNA methyltransferase-associated protein 1 (DMAP1) binding domain, Acyl-CoA synthetase domain and AMP-binding sites. DIP2 regulates axonal bifurcation of the mushroom body neurons in D. melanogaster and is required for axonal regeneration in the neurons of C. elegans. The DIP2 homologues in vertebrates, Disco-interacting protein 2 homolog A (DIP2A), Disco-interacting protein 2 homolog B (DIP2B), and Disco-interacting protein 2 homolog C (DIP2C), are highly conserved and expressed widely in the central nervous system...
