Heavy metal accumulation analysis using bivalve, sponge, sea urchin, and gastropod species as bioindicators.

A comparative assessment of heavy metal accumulation potential in four distinct marine benthic bioindicators: the bivalve Perna perna, the sponge Callyspongia fibrosa, the sea urchin Tripneustes gratilla, and the gastropod Purpura bufo were conducted. These organisms were collected from the same location, and the concentration of ten heavy metals was analyzed in water, sediment and various body parts of the organisms. The bioaccumulation potential was evaluated using the bio-water accumulation factor and bio-sediment accumulation factor.

Comparative analysis of temporal variation of heavy metal accumulation by two sea urchin species from a harbour region, including pre and post COVID 19 lock down period.

Sea urchins are marine invertebrates belonging to phylum Echinodermata, recognized as relevant biological tool for assessing environmental pollution. In the present study, we assessed the bioaccumulation potential of different heavy metals by two sea urchin species, Stomopneustes variolaris Lamarck, 1816 and Echinothrix diadema Linnaeus, 1758, collected from a harbour region, along the south west coast of India, during four different sampling periods for 2 years, from the same sea urchin bed. Heavy metals like Pb, Cr, As, Cd, Co, Se, Cu, Zn, Mn and Ni were analysed from water, sediment and different body parts of sea urchins, such as shell, spine, tooth, gut and gonad.

A rare complication of Yellow Phosphorous poisoning.

Yellow phosphorous is one of the most common toxins reported to cause fulminant hepatic failure. Yellow phosphorous is a component of rodenticides and fireworks, and is freely available over the counter. The mortality rate as high as 27% from fulminant hepatic failure has been reported following ingestion of yellow phosphorous.

Dissemination of multidrug resistant bacteria to the polar environment - Role of the longest migratory bird Arctic tern (Sterna paradisaea).

The ever-increasing prevalence of antibiotic-resistant bacteria(ARB), primarily due to the frequent use and misuse of antibiotics, is an issue of serious global concern. Migratory birds have a significant role in dissemination of ARB, as they acquire resistant bacteria from reservoirs and transport them to other environments which are relatively less influenced by anthropogenically. We have investigated the prevalence of ARB in a long-distance migratory bird, the Arctic tern (Sterna paradisaea) captured from the Svalbard Archipelago.

A Rare Cause of Ortner's Syndrome and a Case-Based Review of Literature.

Ortner's syndrome refers to the compression of the recurrent laryngeal nerve by cardiovascular disorders of various etiologies. We describe a rare case of Ortner's syndrome caused by thoracic aorta aneurysm and a brief review of literature on this unusual cause of Ortner's syndrome. Hoarseness of voice due to the compression of recurrent laryngeal nerve by thoracic aorta aneurysm could be a harbinger of aneurysmal rupture.

Thoracic psammomatous spinal meningioma with osseous metaplasia: A very rare case report.

Thoracic spinal psammomatous meningioma is a rare subtype of meningioma. Among diverse types of mesenchymal differentiation, osseous metaplasia is found to be still rarer. We are presenting a new case of thoracic psammomatous spinal meningioma with osseous metaplasia in a middle aged female which that gives a sense of cancellous bone in the spinal canal.

Retrospective analysis of duodenal injuries: a comprehensive overview.

Background/aim: Duodenal injury is an uncommon finding, accounting for about about 3-5% of abdominal trauma, mainly resulting from both penetrating and blunt trauma, and is associated with significant mortality (6-25%) and morbidity (30-60%).

Patients And Methods: Retrospective analysis was performed in terms of presentation, management, morbidity and mortality on 14 patients of duodenal injuries out of a total of 172 patients of abdominal trauma attending Subharti Medical College.

Results: Epigastric pain (100%) along with vomiting (100%) is the usual presentation of duodenal injuries in blunt abdominal trauma, especially to the upper abdomen.

True vestigeal tail with lumbosacral meningomyelocoel: a rare case report.

A human tail is a rare congenital anomaly with a prominent lesion from the lumbosacro-coccygeal region. It is usually classified either as a true tail or as a pseudo-tail. All the lumbosacro-coccygeal protrusions without the evidence of mesenchymal tissue are classified as pseudo-tail.
