RESUMO

With the current pandemic raging over the world, science and medicine is faced with hereto with unfought enemies or less fought opponent in the form of viruses and consequently, other biotic entities. While researchers are striving to identify and conquer the variants of COVID-19, other innocuous organisms are raising their ugly heads in the form of opportunistic fungal infections. Mucormycosis/Black Fungus is an invasive opportunistic fungal infection caused by mucorale species. It spreads through blood vessels causing thrombosis, ischemia, and necrosis. Population with pre-existing immunocompromised conditions such as Diabetes Mellitus, Malignancy, Long-term immunosuppressant therapy are more susceptible. Mucormycosis associated with Corona Virus Disease-2019 (COVID-19) proved to be catastrophic due to its high mortality rates. Rhino orbital Mucormycosis is the most common form. The primary care physician, being the first and often, (more so in developing countries) and being the only point of contact with a healthcare professional, plays a pivotal role in the diagnosis and management of this condition. The keystone to decreasing mortality is early detection and diagnosis followed by preventive measures to control progression to the brain. A multidisciplinary approach by various specialties is a prerequisite for effective diagnosis and management. Antifungal therapy, surgical debridement, and resection of the affected areas are protocols to be followed. Post-operative defects cause impairment of function, phonetics, and esthetics. Prosthetic rehabilitation of these defects has shown favorable results, especially in the aged and immunocompromised individuals.

RESUMO

Abstract Gout is a form of metabolic arthritis originated on grounds of increased accumulation of monosodium urate (MSU) crystals in joints. Current study focuses on anti-arthritic activities of β-carotene on MSU crystal-induced gouty arthritis rats in comparison with the non-steroidal anti-inflammatory drug, indomethacin. The evaluation was done by taking into account paw oedema, lysosomal enzymes, anti-oxidant enzymes, lipid peroxidation, serum biochemical parameters (uric acid, creatinine), serum cytokines (TNF-α, IL-1β) and histopathological studies. After the induction of MSU crystals, the lysosomal enzymes were increased, antioxidant enzymes were reduced, lipid peroxidation increased and paw volume increased. β-carotene treated at a dose of 10 mg/kg of body weight stabilizes lysosomal enzymes, increases anti-oxidant enzymes, regulates lipid peroxidation and decreased paw volume. The drug β-carotene potentially influences anti-inflammatory effects in arthritic group which is evident from the reduction in the elevated levels of inflammatory cytokines, TNF-α and IL-1β. Current study is an evidence of anti-inflammatory and anti-oxidant effects of β-carotene against MSU-crystal induced gouty arthritis rats.

RESUMO

A new species of argentinid fish, Glossanodon macrocephalus Bineesh Endo, from the Arabian Sea, off the southwestern coast of India, is described on the basis of four specimens (129-164 mm SL). The new species clearly differs from its congeners in the following combination of characters: dorsal-fin rays 10-11; pectoral-fin rays 21-23; anal-fin rays 12-13; pelvic-fin rays 11-12; branchiostegal rays 5; gill rakers on first arch 30-36; vertebrae 47-48; a patch of small conical teeth on middle of lower jaws; predorsal 49-51% SL; prepectoral 36-39% SL; prepelvic 57-58% SL; distance from pelvic to anal-fin origin 26-28% SL; head length 35-39% SL; eye diameter 22-26% HL; snout length 28-30% HL; location of anus immediately anterior to anal-fin origin; broad longitudinal black stripe above lateral line; dark spot on the base to half of pectoral fin; and no teeth on tongue. The new species is a benthopelagic dweller on muddy bottoms in depths of around 300-600 m.

RESUMO

Human metapneumovirus is an emerging pathogen that causes upper and lower respiratory illness. Nursing home outbreaks of infection with this virus can cause severe illness and lead to poor patient outcomes. We report an outbreak investigation in a nursing home during 2018 and infection control guidelines to assist in disease control.

RESUMO

OBJECTIVE: Cardiac surgical operations involving extracorporeal circulation may develop severe inflammatory response. This severe inflammatory response syndrome (SIRS) is usually associated with poor outcome with no predictive marker. Red cell distribution width (RDW) is a routine hematological marker with a role in inflammation. We aim to determine the relationship between RDW and SIRS through our study. METHODS: A total of 1250 patients who underwent cardiac surgery with extracorporeal circulation were retrospectively analyzed out of which 26 fell into the SIRS criteria and 26 consecutive control patients were taken. RDW, preoperative clinical data, operative time and postoperative data were compared between SIRS and control groups. RESULTS: The demographic profile of the patients was similar. RDW was significantly higher in the SIRS versus control group (15.5±2.0 vs. 13.03±1.90), respectively with P value <0.0001. There was significant mortality in the SIRS group, 20 (76.92%) as compared to 2 (7.6%) in control group with a P value of <0.005. Multiple logistic regression analysis revealed that there was significant association with high RDW and development of SIRS after extracorporeal circulation (OR for RDW levels exceeding 13.5%; 95% CI 1.0-1.2; P<0.05). CONCLUSION: Increased RDW was significantly associated with increased risk of SIRS after extracorporeal circulation. Thus, RDW can act as a useful tool to predict SIRS in patients undergoing cardiac surgery with extracorporeal circulation. Hence, more aggressive measures can be taken in patients with high RDW to prevent postoperative morbidity and mortality.

RESUMO

Cardiac hydatid cyst is an uncommon but potentially fatal disease. In cystic Echinococcus humans are an accidental host. Liver and lungs are the most frequently involved organs. Herein a unique case of intramyocardial hydatid cyst of left ventricle along with pulmonary hydatid cyst in a 38-year-old lady is reported. Surgical removal of the cardiac hydatid cyst was done with the aid of cardiopulmonary bypass followed by removal of pulmonary hydatid cyst.

RESUMO

PURPOSE: Urolithiasis is a common urological disorder responsible for serious human affliction and cost to the society with a high recurrence rate. The aim of the present study was to systematically evaluate the phlorotannin rich extract of Sargassum wightii using suitable in vitro and in vivo models to provide scientific evidence for its antilithiatic activity. MATERIALS AND METHODS: To explore the effect of Sargassum wightii on calcium oxalate crystallization, in vitro assays like crystal nucleation, aggregation and crystal growth were performed. Calcium oxalate urolithiasis was induced in male Sprague dawley rats using a combination of gentamicin and calculi producing diet (5% ammonium oxalate and rat pellet feed). The biochemical parameters like calcium, oxalate, magnesium, phosphate, sodium and potassium were evaluated in urine, serum and kidney homogenates. Histopathological studies were also done to confirm the biochemical findings. RESULTS: The yield of Sargassum wightii extract was found to be 74.5 gm/kg and confirmed by quantitative analysis. In vitro experiments with Sargassum wightii showed concentration dependent inhibition of calcium oxalate nucleation, aggregation and growth supported by SEM analysis. In the in vivo model, Sargassum wightii reduced both calcium and oxalate supersaturation in urine, serum and deposition in the kidney. The biochemical results were supported by histopathological studies. CONCLUSION: The findings of the present study suggest that Sargassum wightii has the ability to prevent nucleation, aggregation and growth of calcium oxalate crystals. Sargassum wightii has better preventive effect on calcium oxalate stone formation indicating its strong potential to develop as a therapeutic option to prevent recurrence of urolithiasis.
