COMPARATIVE STUDY
Sébastien Roulier, Julie Arsenault, Philippe Reix, Dominique Dorion, Jean-Paul Praud
The primary aim of the study was to explore cardiorespiratory reflexes originating from laryngeal C fiber endings in the neonatal period. Seventeen lambs were instrumented for recording glottal adductor and diaphragm EMG, heart rate, systemic arterial pressure and respiratory movements. C fiber blockade was induced in eight lambs by 30 mg/kg capsaicin, the remaining nine lambs serving as controls. Cardiorespiratory reflexes were induced in non-sedated lambs by flowing air, menthol or 13% CO2, or by injecting water or 50 microg capsaicin in the laryngeal inlet through an endoscope...

Two patients sustained an ischemic brain stem infarction during medical examination and treatment. The first patient lost consciousness and the spontaneous respiration ceased during X-ray examination of the cervical spine when the neck was hyperextended. After some minutes he regained conciousness but was found to be tetraplegic, and the patient deceased 4 months later. The angiogram revealed thrombosis of the basilar artery. The other patient had profuse nosebleed and was treated with posterior tamponation during which she sat for about 10 min with the neck hyperextended...

J Dittrich, M Havlová, S Nevsímalová
The authors report three patients suffering since infancy from transient attacks of paresis. The flaccid pareses most frequently affect the extremities in a hemiplegic fashion, but occasionally there is monoparesis or quadriparesis. The laterality and degree of the paresis are variable. Conciousness is always preserved, and in two cases attacks were preceded by ocular motor disturbances (skew deviation, nystagmoid jerks and conjugate deviations). Exceptionally, the transient hemiparesis may be preceded by a grand mal epileptic fit, though they are more likely to appear sporadically and independently of the paretic changes...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
