THE adrenergic sympathetic system has been shown to exert a considerable effect on the intra-ocular pressure (Greaves and Perkins, 1952). We know, however, that cholinergic drugs are often effective in lowering the intraocular pressure in glaucoma so that it is possible that the parasympathetic system may also play a part in the control of the tension of the eye. Since the third cranial nerve c...

despite many advances in the field of cancer treatment, intra-cranial tumor cases still have a poor prognosis. this research has been carried out in order to describe age and sex distributions and histopathological characteristics and site of intra-cranial tumors. we studied 425 patients with intra-cranial tumor whose samples were examined in pathology center of imam khomeini hospital from 1991...

Principles of Cerebral Autoregulation Testing Cerebral Autoregulation (CA) is the intrinsic ability of the brain to maintain stable cerebral blood flow (CBF) while mean arterial blood pressure (MAP) and cerebral perfusion pressure (CPP) are changing. It constitutes a regulatory mechanism to provide metabolic substrates under physiological and pathological conditions, for instance after neuro-tr...

Although tuberculosis of the central nervous system is well known, the incidence of intra-medullary tuberculomas is low and a combination of intra-medullary with intra-cranial tuberculomas is extremely rare. This communication reports a case of disseminated (intra-medullary, intra-cerebellar and intra-cerebral) tuberculomas in a sixyear-old girl initially presenting with a spinal tumour syndrom...

A patient with profound panhypogammaglobulinaemia due to common variable immunodeficiency developed two discrete intra-cranial space-occupying lesions, 10 years apart, requiring craniotomy. Histological examination revealed the intra-cranial masses to be granulomata of unknown aetiology on both occasions.

  Chronic suppurative otitis media (CSOM) is a common childhood infectious disease in developing countries. It may be associated with various life threatening intra-cranial or extra-cranial complications. We report a 10 year-male child with a rare combination of right sided unsafe CSOM, mastoiditis, Bezold abscess, sigmoid and transverse sinus thrombosis, and bilateral abducens nerve palsy and ...
