[Doubts about the management of acute otogenic meningitis in infants and children].

The authors present the cases of children suffering from acute otitic meningitis in respect of the applied therapy. On the basis of the courses and the dates of the literature the authors recommend the operation only after the unsuccessful antibiotic therapy. They draw attention to the importance of avoiding the growth of the brain pressure appearing during the operation performed in narcosis and to the importance of cooperating among specialists.

Rostral projections from the hypothalamic arcuate nucleus.

The response of neurones in the medial basal hypothalamus to electrical stimulation in the suprachiasmatic/preoptic region has been studied in rats anaesthetised with urethane. Neurones in the hypothalamic arcuate, periventricular, ventromedial and dorsal premammillary nuclei were antidromically activated by the stimulation showing that such cells send processes in rostral direction outside the median eminence. Tuberoinfundibular and rostrally projecting units were found interspersed in the "hypophysiotrophic" area.
