A 55-year-old mildly hypertensive woman died after having developed a subcortical dementia during the past 9 years, with focal neurological signs. She presented at the age of 46 years with short episodes of dizziness and diplopia, suggesting that transient ischemic attacks involved the posterior fossa structures. Over the next 8 years, she developed difficulty in walking, urinary incontinence and seizures. On examination in 1989, she was severely demented. There was tetraparesis, bilateral arm and leg spasticity with hyperreflexia and bilateral Babinski signs. She showed epilepsia partialis continua involving the eyes, left hemiface and limbs. CT showed hypodensity of the white matter and lacunes in the basal ganglia and centrum semiovale, moderate hydrocephalus with cerebellar and cortical atrophy. Clinical and radiological features were similar to those of Binswanger's disease. Similar cases had occurred in the family affecting the patient's grandfather, father and two brothers, suggesting an autosomal dominant hereditary disease. Postmortem examination disclosed a Binswanger type of leukoencephalopathy caused by a peculiar microangiopathy characterized by a slightly basophilic small arterial granular degeneration of the medial sheath associated with the presence of ballooned smooth muscle cells with clear cytoplasm. Electron microscopic study revealed degenerative changes in the parietal vessels with notable increase of basal-membrane-type material and electron-dense granular deposits. These lesions could correspond to a specific familial pathology of the small arteries of the brain. They are identical to those reported in some patients with autosomal dominant inheritance. For other patients with similar clinical features and the same familial pattern, reported as "hereditary multi-infarct dementia'' and "chronic familial vascular encephalopathy'', there are no sufficient objective pathological facts to consider that they have the same disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Objective: Analyze adolescents' perceptions about support networks and their health needs. Method: Analytical and interpretive study using focus groups conducted in municipal state schools in Fortaleza, in the State of Ceará during the first semester of 2012. The sample comprised 36 male and female adolescents aged between 13 and 16 years attending the ninth grade of the second phase of elementary school. Results: Thematic analysis revealed that the health care support network and interaction between health professionals, education professionals and family members was insufficient, constituting a lack of an integrated network to enable and provide support for health promotion. Conclusion: Coordination between education, health and family services has the potential to act as a support network to help meet adolescents' healthcare needs and demands.
