RESUMEN

OBJECTIVES: to evaluate the heterogeneity of biomedical waste (BW) using Nightingale charts. METHOD: cross-sectional study consisting of data collection on wastes (direct observation of receptacles, physical characterisation, and gravimetric composition), development of a Management Information System, and creation of statistical charts. RESULTS: the wastes with the greatest degree of heterogeneity are, in order, recyclable, infectious, and organic wastes; chemical waste had the most efficient segregation; Nightingale charts are useful for quick visualisation and systematisation of information on heterogeneity. CONCLUSION: the development of a management information system and the use of Nightingale charts allows for the identification and correction of errors in waste segregation, which increase health risks and contamination by infectious and chemical wastes and reduce the sale and profit from recyclables. .

OBJETIVO: avaliar a heterogeneidade dos Resíduos de Serviço de Saúde por meio da aplicação de gráficos nightingaleanos. MÉTODO: estudo transversal, que consiste na coleta de dados sobre resíduos (observação direta dos locais de armazenamento, caracterização física e composição gravimétrica), desenvolvimento de um Sistema de Informação Gerencial e construção de gráficos estatísticos. RESULTADOS: os resíduos que apresentam maior grau de heterogeneidade são os recicláveis, infectantes e orgânicos, respectivamente; o resíduo químico atingiu maior eficiência na segregação; os gráficos nightingaleanos são úteis na visualização rápida e na sistematização das informações sobre a heterogeneidade. CONCLUSÃO: o desenvolvimento de um sistema de informação gerencial e a utilização dos gráficos nigthingaleanos permite identificar e corrigir erros na segregação dos resíduos que impactam tanto no aumento de riscos à saúde e de contaminação por resíduos infectantes e químicos como na redução da comercialização e receita com os recicláveis. .

RESUMEN

A 35-year-old female was referred to our hospital with bilateral loss of vision of two days duration. She gave history of consumption of about 150 ml of neem oil five days back.Examination revealed no perception of light in both eyes. Both pupils were dilated and sluggishly reacting to light. Her fundus examination showed bilateral hyperemic, edematous discs and also edema extending along the superior and inferior temporal vascular arcade. Magnetic resonance imaging (MRI) scan showed bilateral putaminal regions with altered signal, hypointensities in T1-weighted images, hyperintensities on T2-weighted, images and hyperintense on Fluid Attenuation Inversion Recovery (FLAIR) images suggestive of cytotoxic edema due to tissue hypoxia. Her vision improved to 20/200 in both eyes with treatment after two months. This is the first case report of such nature in the literature to the best of our knowledge.

RESUMEN

Neem oil is often used externally as a traditional medicine in India. Its ingestion, even in small doses produces toxic effects like severe metabolic acidosis, seizures, renal failure and encephalopathy. Management is supportive and prognosis is generally good but fatalities may occur. Herein we report an unusual case of neem oil toxicity in a previously normal adult.

RESUMEN

We report an unusual case of neem oil poisoning in a previously normal 5 year old child. The child presented with refractory seizures and was having metabolic acidosis. Late neurological sequelae in the form of auditory and visual disturbances, and ataxia were present.

RESUMEN

Selected oil cakes, neem, castor and mahua, were tried independently and in combination with a chemical nematicide (carbofuran 3G) for the management of Pratylenchus delattrei in crossandra under glass house conditions. The neem oil cake was effective compared to other oil cakes used and there was a synergistic effect when the neemcake was coupled with carbofuran 3G in the management of Pratylenchus delattrei. The treatment resulted in better establishment of seedlings, and with increased plant bio-mass and flower yield.

RESUMEN

Margosa Oil is an extract of the seed of the Neem tree and is widely used as a traditional medicine by Indians in India, Sri Lanka, Burma, Thailand, Malaysia and Indonesia. Used mainly for external applications, it is often administered orally to neonates and infants regularly in small amounts. Margosa Oil causes toxic encephalopathy particularly in infants and young children. The usual features are vomiting, drowsiness, tachypnea and recurrent generalised seizures. Leucocytosis and metabolic acidosis are significant laboratory findings. Management is aimed primarily towards the control of convulsions although supportive management is equally important. Prognosis is usually good but fatalities and neurological deficits have been reported. We report here two infants with Margosa Oil poisoning presenting with encephalopathy.

RESUMEN

Monooctanoin, a hydrophobic solvent, is used clinically to dissolve gallstones via intrabiliary infusion. We report a therapeutic misadventure in which an intravenous injection of the drug resulted in respiratory and cardiac arrest and death. Autopsy findings included pulmonary lipid embolization, detection of monooctanoin in the lung parenchyma, and histopathological evidence of multifocal pulmonary hemorrhagic infarcts. Respiratory compromise has been observed in the standard treatment of patients. In addition, deaths in laboratory animals have been attributed to hemorrhagic pneumonitis. This case illustrates the potential adverse effects of the inappropriate administration of monooctanoin.
