Copper and nickel doped carbon dots for rapid and sensitive fluorescent turn-off detection of bilirubin.

Carbon dots doped with metals and non-metals have gained much popularity due to the enhancement in their optical and electronic properties. In this study, polyethyleneimine-functionalized transition metal (nickel or copper) doped carbon dots (CD, NiCD and CuCD) were synthesized through hydrothermal method. The carbon dots exhibited a blue fluorescence at 470 nm when excited at 350 nm.

Noma Masquerading as Squamous Cell Carcinoma - A Case Report in an AIDS Patient.

Rationale: Cancrum oris, also known as noma, is a rare and rapidly progressing gangrenous infection affecting the oral cavity, commonly seen in malnourished children. We discuss the clinical presentation, diagnostic dilemma and management in a 54-year-old male human immunodeficiency virus-positive patient with oral ulceration clinically resembling squamous cell carcinoma (SCC).

Patient Concerns: The patient had severe oral ulceration with pain and difficulty eating food.

Double Blow in the Tropics: A Case of Concurrent Leptospirosis and Scrub Typhus.

A 34-year-old male, with no history of known previous disease, employed at a ginger farm in South India, presented with a four-day history of high-grade fever and headache. Initially, he received symptomatic treatment but was referred due to hypotension and persistent fever. Investigations showed leucocytosis, thrombocytopenia, abnormal liver function tests, renal dysfunction, and elevated C-reactive protein.

A Novel Method to Fix Paediatric Mandibular Fracture using 2-0 Polyglactin Suture: A Technical Note.

Background: Reduction and stabilisation of fractures at the earliest is valuable in the paediatric age groups. This novel technique focuses on stabilisation of the fracture fragments using vicryl, which has an added advantage to conventional plating and wiring. This study aimed on a novel cost-effective technique of stabilising the paediatric mandibular fracture using 2-0 resorbable polyglactin 910 suture with minimal trauma to tooth buds and bone and adequate stability.

Synthesis and anti-Alzheimer potential of novel α-amino phosphonate derivatives and probing their molecular interaction mechanism with acetylcholinesterase.

Pleiotropic interference may be a prerequisite for the efficient limitation of the progression of multi-factorial diseases such as Alzheimer's disease (AD). Concept of designing the single chemical entity acting on two or more targets of interest has potential advantage in AD therapy. In line with this, rational design and synthesis of frame work of hybrids bearing 2,3-disubstituted quinazolinone, vanillin and α-amino phosphonate scaffolds (5a─v) were carried out.

An Analysis of Leptospirosis Control in a Flood-Affected Region of Kerala and the Role of Accredited Social Health Activists - A Questionnaire Study.

Background: Chengannur, a town in the south Indian state of Kerala, was 1 of the worst affected towns during the floods of 2018. Post-flood, Kerala state was under the threat of many infectious diseases including leptospirosis, but did not report any leptospirosis infections.

Objectives: This study was conducted with the following objectives: (1) Assess the knowledge, attitude and practices regarding the prevention of leptospirosis among the flood affected population and Accredited Social Health Activists (ASHAs) of Chengannur; and (2) Analyze the factors responsible for and contributing to leptospirosis control in the area post flood.

Comparison of Various Severity Assessment Scoring Systems in Patients with Sepsis in a Tertiary Care Teaching Hospital.

Background: Sepsis is a complex condition defined by the systemic response to infection. Severity assessment scoring systems are used to aid the physician in deciding whether aggressive treatment is needed or not. In this study, various severity assessment scoring systems, namely Acute Physiology and Chronic Health Evaluation II (APACHE II), Rapid Emergency Medicine Score (REMS), Sequential Organ Failure Assessment (SOFA), Multiple Organ Dysfunction Score (MODS), Predisposition, Infection, Response, and Organ Dysfunction (PIRO), and Mortality in Emergency Department Sepsis (MEDS), were compared to assess their sensitivity and specificity.

Amidase encapsulated O-carboxymethyl chitosan nanoparticles for vaccine delivery.

This work reports the development of amidase encapsulated O-carboxymethyl chitosan nanoparticles (Ami-O-CMC NPs) of 300±50 nm size by ionic cross-linking method. The prepared Ami-O-CMC NPs had an encapsulation efficiency of 55.39%.

Anthrax meningoencephalitis--declining trends in an uncommon but catastrophic CNS infection in rural Tamil Nadu, South India.

Introduction: Anthrax, a cattle-born zoonosis has been a serious infectious disease and its meningoencephalitic form remains a rapidly fatal illness even now.

Aim: The aim of this paper is to evaluate the incidence and clinical profile of anthrax meningoencephalitis admitted to a teaching hospital predominantly serving a rural population in South India.

Materials And Methods: We made a systematic study of the case records of patients with microbiologically confirmed diagnosis of anthrax meningoencephalitis admitted over a 20-year period.
