RESUMO

Peroneal neuropathy and polyneuropathy are displayed with a variable percentage in subjects affected by eating disorders and in particular by anorexia nervosa. Actually, little is known on features of these complications during the paediatric age. We describe the case of a female adolescent with right peroneal palsy and subclinical polyneuropathy associated with anorexia nervosa (AN). We review previous research about peroneal mononeuropathy and polyneuropathy associated with AN, and we develop a diagnostic and therapeutic protocol to help clinicians recognize and treat these disorders.

RESUMO

INTRODUCTION: We analyze the diagnostic utility of urgent EEG (electroencephalogram) performed in children under 16 years of age in our center. MATERIAL AND METHODS: Descriptive, retrospective, observational study of consecutive patients from 0 to 16 years of age, who underwent an urgent EEG for any reason, from January to December 2022. RESULTS: Of the 388 patients, 70 were children: 37 (52.85%) women, and 33 (47.14%) men. Average age: 6.27 ±â€¯4.809. Of the 70 patients, 6 (8.57%) had previous epilepsy. Reasons for consultation: 17 febrile seizures, 10 first focal seizures, 10 first TCG seizures, 6 paroxysmal episodes, 6 absences, 3 myoclonus of extremities, 3 syncope, 2 SE, 2 visual alterations, 2 low level of consciousness, 2 cyanosis, 2 suspected meningitis or encephalitis, 1 choking, 1 atypical headache, 1 chorea, 1 presyncope, 1 language delay. Of the 70 patients, 47 had a normal EEG (67.14%). Of the 47 patients with a normal EEG, 10 were diagnosed with epilepsy, and 3 of them began receiving antiepileptic treatment upon discharge. None of the patients with suspected syncope or paroxysmal disorder (17 patients, 24.28%) had EEG abnormalities. Of the 17 patients with atypical febrile seizures, 3 had EEG abnormalities. CONCLUSIONS: A third of the EEG records performed in the Emergency Department showed alterations, probably due to the time taken. Almost half of the patients with suspected epilepsy or EE showed EEG abnormalities, which confirmed the diagnosis in these cases and encouraged the clinician to start drug treatment. No case with a high suspicion of epilepsy was dismissed due to the normality of the EEG recording in our series. No patient diagnosed with syncope or paroxysmal disorder had EEG abnormalities. Nearly a quarter of patients with atypical febrile seizures showed EEG abnormalities. We barely register cases of status epilepticus, probably due to the degree of complexity of our center.

RESUMO

Abstract: Introduction: In case of zinc (Zn) deficiency, this mineral becomes a nutrient limiting muscle and bone synthesis. The study in humans on zinc and bone health are few and no reviews have been published on this topic. So, the aim of this narrative review was to consider the state of the art on the correlation between blood zinc, daily zinc intake, zinc supplementation and bone mineral density. Material and methods: A narrative review was performed. Results: This review included 16 eligible studies: eight studies concern Zn blood; three studies concern Zn intake and five studies concern Zn supplementation. Conclusion: Blood zinc levels seem to be lower in subjects with pathology related to bone metabolism. Regarding daily zinc intake, a high proportion of the population, more than 20%, seems to be at risk of having inadequate zinc intake. The literature suggests that an insufficient zinc intake (less than 3 mg/day) could be a risk factor for fractures and for development of osteopenia and osteoporosis. Zinc supplementation (40-50 g/day) could have beneficial effects on bone health in terms of maintaining bone mineral density and faster healing in the event of fractures, with even better results in situations of reduced intake zinc through food.


Resumen: Introducción: En caso de deficiencia de zinc, se limitará la síntesis muscular y ósea. Los estudios en humanos sobre zinc y salud ósea son pocos y no se han publicado comentarios sobre este tema. Por lo tanto, el objetivo de esta revisión narrativa es considerar el estado de la técnica sobre la correlación entre el zinc en la sangre, la ingesta diaria de zinc, la suplementación de zinc y la densidad mineral ósea. Material y métodos: Se realizó una revisión narrativa. Resultados: Esta revisión incluyó 16 estudios elegibles: ocho se refieren al zinc en sangre; tres estudios se refieren a la ingesta de Zn y cinco estudios se refieren a la suplementación de Zn. Conclusión: Los niveles de zinc en sangre parecen ser más bajos en sujetos con patología relacionada con el metabolismo óseo. En cuanto a la ingesta diaria de zinc, una alta proporción de la población, más de 20%, parece estar en riesgo de tener una ingesta inadecuada de zinc. La literatura sugiere que una ingesta insuficiente de zinc (menos de 3 mg/día) podría ser un factor de riesgo de fracturas y para el desarrollo de osteopenia y osteoporosis. La suplementación con zinc (40-50 g/día) podría tener efectos beneficiosos sobre la salud ósea para mantener la densidad mineral ósea y una curación más rápida en caso de fracturas, con resultados aún mejores en situaciones de reducción de la ingesta de zinc a través de los alimentos.

RESUMO

Se presentan los resultados obtenidos en la validación de un método analítico por cromatografía líquida de alta resolución, para la determinación de ivabradina en comprimidos, el cual se diseñó para identificar y cuantificar a dicho analito, con la utilización de una columna RP-18 (150 x 4,6 mm) 5 µm y un detector UV-Vis a una λ: 285 nm. Dicho método se empleará para el control de la calidad y estabilidad de ivabradina comprimidos. El método fue validado siguiendo una metodología de trabajo de acuerdo a los lineamientos de la Conferencia Internacional sobre Armonización de Requisitos Técnicos para el Registro de Medicamentos de uso humano, Validación de procedimientos analíticos (ICH Q2), obteniendo los siguientes resultados: linealidad (r2 = 0,999), precisión Desviación estándar relativa (DSR) = 0,67 % para comprimidos del lote piloto y DSR=0,31% para comprimidos del lote comercial) y exactitud recuperación media=100,2%, demostrando de esta manera que el método propuesto es aplicable a la dosificación de ivabradina en comprimidos, tanto en el análisis del producto terminado cómo en los estudios de estabilidad.
