Epidemiology and management of orbital fractures
A. Cruz,G. C. D. Eichenberger +1 more
TL;DR: Oculoplastic surgeons in collaboration with other medical specialists are in a prime position to assess and manage these cases, taking into consideration that most complications of these fractures are related to the globe.

Neuroanatomical and psychopharmacological evidence for interaction between opioid and GABAergic neural pathways in the modulation of fear and defense elicited by electrical and chemical stimulation of the deep layers of the superior colliculus and dorsal periaqueductal gray matter.
G. C. D. Eichenberger,Sandro José Ribeiro,M.Y Osaki,R.Y Maruoka,G.C.C Resende,Lissandra Castellan-Baldan,Sônia A. L. Corrêa,L. da Silva,Norberto Cysne Coimbra +8 more
TL;DR: Findings suggest an opioid modulation of the GABAergic inhibitory inputs controlling the aversive behavior elicited by midbrain tectum stimulation, and immunohistochemical evidence suggests that the dorsal mesencephalon is rich in beta-endorphin-containing neurons and fibers with varicosities.

Effects of opioid receptor blockade on defensive behavior elicited by electrical stimulation of the aversive substrates of the inferior colliculus in Rattus norvegicus (Rodentia, Muridae).
Norberto Cysne Coimbra,M.Y Osaki,G. C. D. Eichenberger,J.G. Ciscato,C.E.B. Jucá,C.R. Biojone +5 more
TL;DR: Results suggest that endogenous opioids are involved in the modulation of the aversive behavior elicited by midbrain tectum stimulation, and it is possible that µ1-opioid receptor located in this nucleus may be critically implicated in this neural circuitry.

Chemical neuroanatomical and psychopharmacological evidence that κ receptor-mediated endogenous opioid peptide neurotransmission in the dorsal and ventral mesencephalon modulates panic-like behaviour.
Juliana Almeida da Silva,Renato de Freitas,G. C. D. Eichenberger,Cláudia Maria Padovan,Cláudia Maria Padovan,Norberto Cysne Coimbra +5 more
TL;DR: The present data offer a neuroanatomical basis for both intratectal axo-axonic/pre-synaptic and tecto-nigral axo -somatic opioid inhibition of GABAergic nigro-tectal neurons that modulate the dorsal midbrain neurons related to the organisation of fear-related emotional responses.

Ossifying fibroma: a rare cause of orbital inflammation.
Antonio Augusto Velasco e Cruz,Victor Marques de Alencar,Victor Marques de Alencar,Ana Rosa Pimentel de Figueiredo,Sheila de Paula,G. C. D. Eichenberger,Fernando Chahud,Moisés Salgado Pedrosa +7 more
TL;DR: Regardless of the histologic pattern (trabecular or psammomatoid), ossifying fibromas can induce a substantial degree of orbital inflammation in children and must be included in the differential diagnosis of acute orbital inflammation during childhood.
