La pubertad precoz, un enigma

La edad de la pubertad ha bajado en los países desarrollados.
Todo indica que en el mundo occidental los niños alcanzan la pubertad a edades cada vez más tempranas, algo que se ha transformado en un enigma para los científicos.
Se han detectado casos de niñas que tienen los primeros signos ya a los siete años.
Está aceptado que la edad en que una niña empieza a desarrollar signos de pubertad es a los 10 años. Entre los niños ocurre un poco más tarde, por lo general a los 11 y medio.
Sin embargo, estas cifras han caído en los países desarrollados.
En 1990 ya el promedio para las niñas era de ocho años. Algunos expertos aseguran que en la actualidad ha bajado a siete.
Las razones para este fenómeno son desconocidas, aunque existen varias teorías.

Un artículo presenta el caso de una paciente con sumatriptan y un IRSS. Interesante a recordar al momento de indicar IRSS. Entrez PubMed

[Serotonin syndrome as a result of concomitant use of paroxetine and sumatriptan]

Hendrix Y, van Zagten MS.
A 65-year-old woman was referred with confusion, strange behaviour, sinus tachycardia, hypertension and hyperthermia. She had been taking sumatriptan and paroxetine and recovered completely after discontinuation of these agents. The diagnosis was ‘serotonin syndrome’, a result of overstimulation of 5-HT(1A) receptors in the raphe nuclei of the brainstem. It is a complication of the use of serotonergic agents and is associated with the rapid onset of mental, autonomic and neurological symptoms. Treatment consists of discontinuation of the suspected medication and, in severe cases, providing symptomatic relief. Given the frequent prescription of (combinations of) serotonergic agents, one should be aware of this complication.

El comite por la seguridad farmacológica del Ministerio de Salud Inglés ha encomendado un trabajo sobre el uso de la olanzapina y la risperidona en pacientes con demencia. La conclusiones a las que llega se agregan en este linkAtypical antipsychotic drugs and stroke

Prescribing advice
CSM has advised that risperidone or olanzapine should not be used for the treatment of behavioural symptoms of dementia.
Use of risperidone for the management of acute psychotic conditions in elderly patients who also have dementia should be limited to short-term and should be under specialist advice (olanzapine is not licensed for management of acute psychoses).
Prescribers should consider carefully the risk of cerebrovascular events before treating any patient with a previous history of stroke or transient ischaemic attack. Consideration should also be given to other risk factors for cerebrovascular disease including hypertension, diabetes, current smoking and atrial fibrillation.
