Nine cases (seven men and two women, mean age 64.5 years) of classical lacunar syndromes due to intracerebral hemorrhage are reported. Three patients presented with pure motor hemiparesis (two putaminal hematomas with proportional weakness and one cortical hemorrhage with brachio-crural hemiparesis). Four patients presented with sensorimotor stroke due to thalamo-capsular hemorrhage. The last two patients had thalamic hemorrhage causing ataxic hemiparesis or dysarthria-clumsy hand syndrome. Four subjects had arterial hypertension, one was diabetic, and two were treated with anti-vitamin K. Abrupt onset was noted in all instances. Only one patient experienced moderate inaugural headaches. Good recovery occurred in all cases. Lacunar syndromes are a very uncommon presentation of intracerebral bleeding. Hemorrhages are yet the second etiology of such syndromes. Distinguishing hemorrhage from infarction is not clinically possible and needs early unenhanced CT scan. 相似文献

Hypnic headache is a rare short-lasting headache occurring exclusively during sleep in the elderly population. First described
in 1988 by Raskin, this headache syndrome was adopted by the International Classification of Headache Disorders in 2004 within the “other primary headache” group (code 4.5). Since then, additional case reports and case series were published
and provided data to best understand hypnic headache. This review highlights new findings to discuss the relevance of actual
diagnostic criteria and the treatment approach of this nocturnal headache syndrome. We also consider hypnic headache pathophysiology
that remains speculative. 相似文献

In a cross sectional sample of 655 Glasgow babies the mean birthweight, after adjusting for other factors, of those with unemployed fathers was 150 g less (P less than 0.02) than for babies whose fathers were employed. A longitudinal study of 107 babies from 2 contrasting areas in Glasgow one of which was a socially deprived area was carried out concurrently. The deficit in length of 2.6% for infants from the deprived area at age 12 months was completely explained by adjusting for length at 1 month, father''s height, and father''s employment status (P less than 0.01). The effect of unemployment on the babies'' birthweight was not affected by adjustment for social class. Unemployment may be related to poor infant growth in inner city areas and a national study is needed to see if the recent rise in unemployment has affected this association. 相似文献

BACKGROUND: Since the initial report of Ford et al in 1998 no further study has evaluated radiosurgery of the trigeminal nerve in chronic cluster headache (CCH). METHODS: We carried out a prospective open trial of neurosurgery and enrolled 10 patients (nine men, one woman; mean age 49.8 years, range 32-77) presenting with severe and drug resistant CCH (mean duration 9 years, range 2-33). The cisternal segment of the nerve was targeted with a single 4 mm collimator (80-85 Gy max). RESULTS: The mean follow up was 13.2 months. No improvement was observed in two patients and three patients had no further attacks. Three patients showed dramatic improvement with a few attacks per month or very few attacks over the last six months. Two patients were pain free for only one and two weeks and their headaches recurred with the same severity as before. Three patients developed paraesthesia with no hypoaesthesia, one developed hypoaesthesia, and one developed deafferentation pain. CONCLUSIONS: The rate and severity of trigeminal nerve injury appeared to be significantly higher than in trigeminal neuralgia, and this study does not support the positive results of the study of Ford et al. We consider the morbidity to be significant for the low rate of pain cessation, making this procedure less attractive even for the more severely affected subgroup of patients. 相似文献

The authors report a case of osteitis fibrosa cystica of the cervical spine with spinal cord and root compression. Histological diagnosis was made in the post-surgical phase during which acute renal failure and hypercalcemia developed; a parathyroid nodule was found and subsequently excised. 相似文献
