Yasser Aladdin, MD James Scozzafava, MD, FRCPC Taim Muayqil, MD Maher Saqqur, MD CLINICAL PEARLS 1. The palatal myoclonus in symptomatic cases is usually silent as the involved muscle is the levator veli palatini. This is in contrast to the audible clicking sound (generated by the synchronous collapse of the eustachian tube) in patients with essential palatal myoclonus in which the involved mus...

Two cases of spontaneous intracerebral haemorrhage in adolescent girls suspected of having multiple sclerosis are reported. Surgical evacuation of haematomas in the left thalamus and left side of the pons, respectively, was performed with excellent recovery in both cases. Some clinical and pathological aspects of small arteriovenous malformations are discussed and the pertinent literature revie...

Intracisternal injection of blood in the rat produces an angiographically demonstrable biphasic vasospasm. Lesioning at the level of the mesencephalon of the ascending catecholamine pathways from locus coeruleus in the pons and the A1 and A2 nuclei in the medulla oblongata prior to cisternal blood injection prevents the development of both acute and late spasm. Selective lesioning in the medull...

THE RAPID EYE MOVEMENT (REM) STAGE OF SLEEP IS CHARACTERIZED BY CORTICAL AND HIPPOCAMPAL ACTIVATION, RAPID EYE MOVEMENTS, SILENCING OF brainstem aminergic neurons, and postural atonia.1 Cholinergic activation plays an important role in the generation of REM sleep, since pontine microinjections of cholinergic agonists into the pontine reticular formation trigger or enhance a rapid eye movements ...

A most unusual case of right-sided ataxic hemiparesis with left trigeminal involvement is reported. Computerized tomographic scan revealed a small hemorrhage in the basis pontis.

Herein, we report a case of abrupt suprachoroidal hemorrhage (SCH) that developed during peritoneal dialysis in a patient with proliferative diabetic retinopathy. A 53-year-old female patient visited our clinic with blurred vision due to vitreous hemorrhage and proliferative diabetic retinopathy. Her medical history included diabetes, hypertension, chronic renal failure, and she had received sc...

Case Report A 71-year-old female suffered a sudden onset of diplopia, dysarthria and paresthesias of the left hemiface and the upper left extremities. She had hypertension and dyslipidemia. Upon admission, the patient showed a right IV cranial nerve palsy, skew deviation, right internuclear ophthalmoplegia, dysarthria, left central facial palsy, left hemihipoestesia, right appendicular ataxia a...

BACKGROUND AND PURPOSE The overall mortality rate of primary pontine hemorrhage (PPH) in recent studies is 40-50%. The aim of the present study was to analyze the predictive value of clinical and neuroradiologic parameters concerning the outcome of patients with PPH. METHODS We reviewed the clinical data of 29 consecutive patients (mean age, 59 +/- 13.5 years; 12 women, 17 men) with PPH. Nati...
