[Morbidity due to intracerebral hemorrhage]. / Morbilidad de la hemorragia intracerebral.

INTRODUCTION: Intracerebral hemorrhage (HIC) represents 10-30% of all stroke. Epidemiological studies have shown factors associated with its high mortality, but those which might lead to lower morbidity are little known. OBJECTIVE: To find the factors which may influence the functional state of a series of patients with intracerebral hemorrhage. PATIENTS AND METHODS: We made a prospective study of 203 patients with intracerebral hemorrhage. We recorded vascular risk factors, arterial blood pressure, laboratory and neuroimaging parameters obtained on admission. The functional condition when discharged from hospital was evaluated on the Rankin Scale, in three categories: independent (Rankin 0-1), partially dependent (Rankin 2-3) and totally dependent patients (Rankin 4-5). RESULTS: There was a 23.2% death rate. Of the 156 patients who survived, at the time of hospital discharge 35.8% had a score of 0-1, 50.6% a score of 2-3 and 13.4% a score of 4-5 on the Rankin Scale. Age (p < 0.005), hyperglycaemia (p < 0.05) and size of hemorrhage (p < 0.05) were associated with increased morbidity. CONCLUSIONS: The functional condition on hospital discharge was better in younger patients with lower levels of glycemia on admission and smaller hematomas on CT.

[Progressive degenerative aphasia: clinical and neuroradiological observations in 18 cases]. / Afasia progresiva degenerativa: observaciones clínicas y neurorradiológicas en 18 casos.

INTRODUCTION: In some types of degenerative dementia aphasia is the main disorder. In primary progressive aphasia. (PPA) atrophy is limited to the dominant peri-sylvan region. We present 18 cases of progressive aphasia of degenerative origin, with or without dementia. MATERIAL AND METHODS: We describe the clinical and neuro-radiological findings in 3 patients with 'aphasic dementia and motor neuron disease (ADMND)', 7 with 'semantic dementia' (DS), and 4 with 'fronto-temporal dementia' with 'marked non-fluent aphasia' (AFTD). Criteria published in recent years were used. RESULTS: In patients with ADMND non-fluent aphasia progressed to global aphasia, with dementia occurring after 2-9 months, and death after an average of 17 months. In cases with SD, initial anomic aphasia progressed to transcortical sensory or global aphasia, and in patients with AFTD, Broca's aphasia or motor transcortical aphasia progressed to global aphasia. Seven of these patients had been initially diagnosed as having PPA and became demented after two years or more. In most of the cases the cognitive disorder had the characteristics of fronto-temporal dementia. All cases had cortical atrophy or asymmetrical cortical or cortico-subcortical atrophy. The 4 cases of non-fluent PPA were not demented after 21 months-6 years of illness, and showed perisylvan and left fronto-temporopolar atrophy. CONCLUSIONS: The PPA may correspond to the initial form of at least three varieties of dementia, usually the fronto-temporal type. Dementia occurs after two years or more, except in patients with motor neurone disease, when there is a latent period of less than one year.

[Familial strio-pallido++-dentate calcification]. / Calcificación estriopalidodentada familiar.

INTRODUCTION: Calcification of the dentate nucleus of the cerebellum may be seen on cerebral CT in 0.3-0.5% of patients with no symptoms or extra-pyramidal signs. Although there are many causes, some cases show a family incidence. Clinical cases. We present two cases, mother and son, in whom the predominant clinical findings were poor language and a bilateral extrapyramidal syndrome. Laboratory tests, hormone and immunological studies were normal. In both patients cerebral CT showed bilateral calcification of the basal nuclei and dentate nuclei of the cerebellum. DISCUSSION: Our patients fulfilled the clinical and neuro-imaging criteria described in familial strio-pallido-dentate calcification. There is no relationship between the duration and intensity of symptoms, and the extension of the calcification. However, all patients with calcification show clinical features. The predominant features are poor language and a bilateral extra-pyramidal syndrome. These observations indicate that in patients with calcification of the basal ganglia and dentate nuclei of the cerebellum it is necessary to study first degree relatives in order to identify the condition.

[Comparison of hypertensive and non-hypertensive lacunar infarcts]. / Comparación entre infartos lacunares hipertensivos y no hipertensivos.

INTRODUCTION: Arterial hypertension and hypohyalinosis of the arterias perforantes are said to be the commonest cause of lacunar infarcts, although other etiological factors and anatomo-pathological lesions are described more and more frequently. We designed a study to compare the clinical topographic and prognostic characteristics of patients with hypertensive and non-hypertensive lacunar infarcts. MATERIAL AND METHODS: We selected 51 patients with lacunar infarcts: in 23 (45%) arterial hypertension was the only etiological factor recognized. In 28 (55%) other risk factors (16 diabetes mellitus, 17 cardiopathy, 8 hyperlipemia, 13 cigarette smoking and 11 alcoholism) were seen. We evaluated the form of presentation, the type of infarct and whether this was associated with headache. The degree of defect was determined on admission using the Canadian scale. The size of the infarct was measured on CT or RM, using whichever measurement was greater. The evolution of the condition was determined on the Canadian scale and the index of Barthel after three months. RESULTS: Age and sex distribution was similar to both groups. Motor hemiparesia was the commonest lacunar syndrome and the distribution was similar. There was no difference in form of onset, association with headache or neurological defect between the hypertensive and non-hypertensive lacunar infarcts. The topographical distribution, the presentation of single or multiple lesions, the size of the infarcts and the prognosis were similar in both groups. CONCLUSIONS: Lacunar infarcts, whether hypertensive or not, show no differences regarding clinical, neuro-radiological or evolutionary characteristics.

[Preoperative diagnostic imaging in stump appendicitis]. / Diagnóstico preoperatorio por métodos de imagen de una apendicitis del muñón.

Stump appendicitis is a rare condition in which the diagnosis is often delayed and is eventually reached during exploratory surgery. Knowledge of stump appendicitis makes it possible to reach the diagnosis using imaging techniques and thereby reduce the morbidity of this condition. We present the case of a patient with appendicitis of the appendicular stump that was diagnosed prior to surgery using plain-film radiography and abdominal CT.
