ABSTRACT

Vasculitic midline destructive lesions can be a complication of cocaine use. We report a 44-year-old man who presented with a two months history of left facial pain associated with ipsilateral facial paralysis and a cheek phlegmon. Magnetic resonance imaging showed broad soft tissue destruction linked to important cranial nerve involvement. Antibiotic and antifungal therapy was started and multiple surgical debridement procedures were performed, with no clinical improvement. Microbiological analysis was negative. Finally, thanks to the histologic findings corresponding to vasculitis and granuloma formation and the history of cocaine abuse, a cocaine induced midline destructive lesion was diagnosed.

ABSTRACT

Um grande número de agentes presentes no ar inalado, ambiental ou ocupacionalmente, pode causar sintomas e doenças das vias aéreas superiores. Infelizmente o estabelecimento do nexo causal entre os mais diversos tipos de exposições que podem desencadear essas doenças não faz parte da rotina dos profissionais da saúde afeitos a essa questão. Uma extensa lista desses agentes e suas relações com as atividades e o desencadeamento dessas enfermidades estão disponíveis na literatura. Destacamos as rinossinusopatias, as disfonias, as ulcerações e perfurações do septo nasal e o elevado número de neoplasias da cavidade nasal e dos seios paranasais, que podem estar associados às atividades laborativas. Os procedimentos diagnósticos para investigação da etiologia ocupacional, apesar de disponíveis, ainda são pouco utilizados rotineiramente. Geralmente o reconhecimento precoce do agente causal e o afastamento da exposição podem resolver o problema evitando sua cronificação, pois, como nas demais doenças respiratórias ocupacionais, os programas de prevenção e o controle são elementos imprescindíveis para o equacionamento dessas enfermidades.


A great number of agents found in inhaled air, whether in the environment or in the workplace, can cause symptoms and diseases of the upper respiratory tract. Unfortunately, establishing the cause-and-effect relationship between exposure to one of the various types of agents that can provoke such diseases and the diseases themselves is not routine practice among the health professionals involved. A comprehensive list of these agents and their relationships with the effects and onset of such illnesses is available in the literature. Chief among these ills are rhinosinusitis, dysphonia and ulceration/perforation of the nasal septum, as well as tumors in the nasal cavity or paranasal sinuses, all of which can be work related. Although widely available, diagnostic procedures for the investigation of occupational etiology are not yet routinely employed. In general, early identification of, and discontinuation of the contact with, the causal agent can resolve the problem, thereby averting the development of the chronic form of the disease. As with other types of occupational respiratory diseases, prevention and control programs are indispensable in the fight against these illnesses.

ABSTRACT

El consumo materno de etanol durante la lactancia altera la composición de la leche, provoca la aparición de etanol y acetaldehído en la leche y agrava los efectos del etanol en las crías de ratas. De este modo, fueron estudiados los efectos del etanol, administrado a las ratas madres durante la lactancia, sobre el epitelio respiratorio y en las glándulas septales anterior y posterior de las crías lactantes con 21 días de vida postnatal. Las ratas recibieron etanol al 20% en el bebedero, ad libitum durante los 21 días que amamantaron. Los controles recibieron un volumen similar de agua sin alcohol. Las crías fueron sacrificadas en el 21 día. Las cabezas fueran cortadas frontalmente. Los cortes seriados de 6 µm de grosor fueron teñidos con hematoxilina y eosina. Fueron determinados los parámetros nucleares de los epitelios respiratorio y glandular, así como los volúmenes citoplasmático y celular, relación núcleo-citoplasma, densidades numérica y superficial y espesor del epitelio. El peso corporal medio de las crías control fue 34,9 g y en las tratadas 20,2 g. Histologicamente, el epitelio respiratorio se mostró adelgazado en el grupo tratado, constituido por células abundantes y menores, con núcleos menores. La glándula septal posterior presentó ácinos menores. En este trabajo, el etanol indujo un cuadro de hipotrofia epitelial (respiratorio y glandular), indicando una acción directa sobre las células de la mucosa nasal, además de retardar el desarrollo de las crías intoxicadas.


Maternal ingestion of ethanol during lactation alters the chemical composition of milk, results in the appearance of ethanol and acetaldehyde in milk, and exacerbates the effects of ethanol on the rat pups. So that, the effect on respiratory epithelium and anterior and posterior septal glands in 21-day-old suckling pups of ethanol treated mothers was studied. Female rats received dinking water ad libitum containing ethanol (20%) throughout the whole lactation. Control animals received a similar volume of water without ethanol. Lactent rats (21 day-old) were killed by lethal dose of anesthetic. The heads were serially sectioned (6µm thick) in a frontal plain, and stained with haematoxylin and eosin. Cell nuclear parameters were estimated, as well as cytoplasm and cell volume, nucleus-cytoplasm ratio, number and surface densities, and epithelial thickness. Mean body weight of the pups was 34.9 g for the controls and 20.2 g for the treated group. Histologically, the respiratory epithelium was thinner, with more numerous and smaller cells and small nuclei. The posterior septal glands showed smaller acini. In this paper, ethanol induced epithelial (respiratory and glandular) hypotrophy, indicating a direct action in nasal mucous cells, besides retarded development in pups.

ABSTRACT

Objetivo: Demostrar que la aplicación de ketanserina en ungüento al 2 por ciento acelera el cierre de las laceraciones de la mucosa septal producidas intencionalmente en consejos Nueva Zelanda al compararlas con un placebo con el mismo vehículo que la ketanserina (polietilenglicol). Se realizó un estudio longitudinal, prospectivo, experimental, comparativo y ciego, utilizando 10 conejos Nueva Zelanda divididos en dos grupos al azar, a los que se les realizó rinotomía lateral y bajo visión microscópica se laceró la mucosa septal incluyendo mucopericondrio. Posteriormente se aplicó ungüento con placebo (polietilenglico) o ketanserina al 2 por ciento durante cinco días, tomando fotografía antes y después de la aplicación y muestras histológicas al primero, tercero y quinto días las cuales se analizaron en el departamento de Anatomía Patológica con tinción de hematoxilina-eosina. Se concluye que la ketanserina en ungüento al 2 por ciento acelera el cierre clínica e histológicamente (mayor cantidad de colágena y fibroblastos) al compararlas contra placebo. El análisis estadístico se realizó con la prueba de Pickman Welch, obteniendo una p< 0.05
