Tissue Staplers in Transcervical Diverticulectomy - A Novel Approach to Closing Zenker's Diverticulum.

Zenker's diverticulum is a type of false pulsion diverticulum arising from the gap between the inferior constrictor muscle and the cricopharyngeus, secondary to heightened pressure within the lumen and a malfunctioning cricopharyngeal muscle. Surgery is the mainstay of treatment having exceptional success rates with the post-surgical risk of recurrence lying between 4.2 and 18.

A Nose Bleed Reveals Rhabdomyosarcoma's Seed.

Embryonal rhabdomyosarcoma is the malignant mesenchymal proliferation of undifferentiated skeletal muscle. It is the most common soft tissue tumour found in children. Head and neck location accounts for 40% of the cases with the most common variants being of embryonal Nasopharyngeal RMS is a type of parameningeal RMS (arising from tissues adjacent to the meninges) having propensity for CNS and known for having a poorer prognosis, early recurrence, rapid growth and invasion to adjacent structures.

Angiomyxolipoma of the Cheek: A Rare Oral Tumour.

Angiomyxomas, also known as vascular myxolipomas, are a rare type of soft tissue tumor characterized by the proliferation of adipose tissue within a myxoid stroma accompanied by multiple vascular channels. They represent a distinct variant of lipomas and require differentiation from other benign and malignant lipoma subtypes. Despite their rarity, only a few cases of angiomyxolipoma have been documented in medical literature.

An underdog under the mandible: Pantoea agglomerans abscess of the submandibular region- a case report.

Background: Pantoea agglomerans is a gram negative, aerobic/facultative anaerobic, rod shaped bacilli commonly isolated from plants, soil, food and faeces.(1) It is a rare cause of opportunistic infections in humans acquired mainly via two major routes being, wound infection or hospital acquired.

Case Report: Here, we encountered a landmark, first of its kind, head and neck manifestation of a cervical soft tissue abscess with Pantoea agglomerans being the miscreant.

Dirofilariasis of the Nasal Dorsum: A Case Report.

Dirofilariasis is an infection caused by the filarial nematode Dirofilaria. primarily causes pulmonary dirofilariasis, while subcutaneous dirofilariasis is usually caused by and but can rarely be caused by as well. Here we report a rare case where in a 26-year-old with a history of international travel presented with swelling over the nasal dorsum.

Cricopharyngeal Myotomy; a Rescue Surgery for Dysphagia in Lateral Medullary Syndrome.

Lateral medullary syndrome/Wallenberg syndrome, is a neurological disorder occurring due to ischemia in the lateral part of medullary oblongata resulting in wide range of symptoms. Dysphagia is usually exhibited in severe and persistent form in LMS. Hence timely intervention is mandatory before the patient further worsens.

Effect of Preeclampsia and Gestational diabetes mellitus on Neonatal Distortion Product Otoacoustic Emissions: A Tertiary Care Center Study.

Purpose: To determine whether preeclampsia and gestational diabetes mellitus is a risk factor for cochlear damage and sensorineural hearing impairment in infants.

Materials And Methods: Longitudinal study was conducted in 2 tertiary referral centers. 1068 neonates were included, who were born to preeclampsia, gestational diabetes mellitus, and healthy mothers.

Digitally-enhanced lubricant evaluation scheme for hot stamping applications.

Digitally-enhanced technologies are set to transform every aspect of manufacturing. Networks of sensors that compute at the edge (streamlining information flow from devices and providing real-time local data analysis), and emerging Cloud Finite Element Analysis technologies yield data at unprecedented scales, both in terms of volume and precision, providing information on complex processes and systems that had previously been impractical. Cloud Finite Element Analysis technologies enable proactive data collection in a supply chain of, for example the metal forming industry, throughout the life cycle of a product or process, which presents revolutionary opportunities for the development and evaluation of digitally-enhanced lubricants, which requires a coherent research agenda involving the merging of tribological knowledge, manufacturing and data science.

Development of a Formability Prediction Model for Aluminium Sandwich Panels with Polymer Core.

In the present work, the compatibility relationship on the failure criteria between aluminium and polymer was established, and a mechanics-based model for a three-layered sandwich panel was developed based on the M-K model to predict its Forming Limit Diagram (FLD). A case study for a sandwich panel consisting of face layers from AA5754 aluminium alloy and a core layer from polyvinylidene difluoride (PVDF) was subsequently conducted, suggesting that the loading path of aluminium was linear and independent of the punch radius, while the risk for failure of PVDF increased with a decreasing radius and an increasing strain ratio. Therefore, the developed formability model would be conducive to the safety evaluation on the plastic forming and critical failure of composite sandwich panels.
