In this prospective study of 239 patients, 88 (37%) suffered from post-lumbar puncture headache (PPH). The pain was located within the region innervated by the trigeminal nerve in 49% of the drawings, within the occipital and/or suboccipital region in 11%, and within the combined trigeminal/occipital region in 39%. The headache was unilateral at least once in 34% of the patients. Changes in pain location from one region to the other and/or between bilateral and unilateral headache were observed in 54% of the patients throughout the PPH period. Associated symptoms were experienced by 85%, nausea (73%) and dizziness (60%) being the most frequently reported. In the upright position, nausea, dizziness, and tinnitus tended to be present during a fairly large part of the PPH period (57-63% of the days), vomiting occurring only occasionally (28%). The intensity of associated symptoms was positively correlated to PPH severity. Pain in the combined trigeminal/occipital region was most severe and related to more associated symptoms than pain in other regions, and unilateral pain was milder than bilateral pain. Pain in the occipital and/or suboccipital region was mildest. The severity of nausea decreased significantly on the last 2 days of the PPH period, and the intensity of dizziness decreased when PPH was about to subside. Tinnitus is probably due to a cochlear dysfunction, and presents special characteristics. Its incidence was not clearly related to PPH severity and it increased with increasing duration of PPH; its intensity did not decline when PPH was about to wane.
Hyperventilation-induced dizziness is often thought to be psychogenic, but its effects in the presence of known vestibular disease have not been adequately examined. In this study hyperventilation was tested in two models of vestibular disease. These were, first, patients with profound unilateral vestibular deficit (prior translabyrinthine acoustic neuroma resection [postsurgery group]) and, second, patients with variable unilateral vestibular deficit (unoperated unilateral acoustic neuroma [presurgery group]). Patients were hyperventilated for 90 seconds. Using infrared videonystagmography, 100% of the 32 postsurgery patients and 82% of the 28 presurgery patients developed nystagmus with hyperventilation. Hyperventilation was more sensitive than head shake for eliciting nystagmus in these models. The false-positive rate for nystagmus in 29 normal volunteers was 3.5% for hyperventilation and 10% for head shake. Our results show that hyperventilation can unmask underlying vestibular disease.
BACKGROUND: Menopausal symptoms include hot flushes, insomnia, nocturnal sweating, dizziness, headaches and palpitations. These symptoms reflect adaptation of the body to estrogen deprivation which affects various central neurotransmitters. METHODS: In this study, the efficacy has been tested of a plant product based on extracts of the leaves of Salvia officinalis (sage) and Medicago sativa (alfalfa) in the treatment of hot flushes in 30 menopausal women with these symptoms. RESULTS: Hot flushes and night sweating completely disappeared in 20 women: four women showed good improvement and the other six showed a reduction in symptoms. GnRH and TRH tests were performed in 8 women to evaluate TSH and Prl responses before and after 3 months of therapy. The plants product induced a significant increase in Prl and TSH response to TRH. Basal levels of estradiol, LH, FSH, Prl and TSH were unchanged. CONCLUSIONS: The product seams to have a central slight antidopaminergic action without side effects and is an effective agent in the treatment of menopausal symptoms.
