Weber’s syndrome is characterized by a third nerve palsy associated with contralateral hemiparesis because of a damage to the cerebral peduncle, due to multiple etiologies.
We report the case of a 40 years old man with no history of diabetes mellitus or hypertension who suddenly presented with diplopia and left hemiparesis. The MRI scan showed an angioma in the midbrain. Its relevance lies in the rare etiology of this syndrome and its spontaneous resolution.
Primary hemorrhagic cerebrovascular accident in brain parenchyma is known as spontaneous intracerebral hemorrhage. It uncommonly occurs during pregnancy and puerperium. We briefly describe this clinical entity, although it is rare, is important to know its existence in order to give a good treatment.
Cavernomas are uncommon vascular lesions, with presenting symptoms after third decade of life. They are asymptomatic in 20% of cases, rising to 40% in familiar cases. Clinical picture is variable but seizure is the most common presenting feature. We report, briefly, two clinical cases and comment some data from the literature.
Involuntary abnormal movements may occur as part of the symptomatology of acute stroke or may be delayed or progressive. We report two cases of post-stroke hemiballismus and contralateral tremor. Both patients presented acute hemiballismus. In one of the patients, the tremor started with acute symptomatology and the other was delayed. We discuss the possible pathogenic mechanisms for their movement disorders. To our knowledge, this is the first report of two cases with the unusual presentation of post-stroke hemiballismus and contralateral tremor.
We report two cases of patients who ingested methanol and suffered a cerebral affectation demonstrated in the cranial CT as hypodensities in the putaminal nucleus and cerebral white matter, compatible with necrosis.
We present a case of alobar holoprosencephaly and cebocephaly in a newborn girl associated to a short arm deletion chromosome 18, as a result of a maternal balanced traslocation 6p/18p.
Trypanosoma cruzi infection is far for being solved in Latin America. Recent research is strongly biased to basic investigations mostly at molecular levels putting aside important clinical involvement and epidemiological findings. Here, we present evidence that Trypansoma cruzi affect neural systems including the autonomous one. Oral and genital routes of transmission of this parasite as well as the cross-reactions and false-positives described with different serological tests including those used to test HIV must be checked out before putting the almost always fatal diagnoses of Chagas disease.
Briefly we described the posteroventral pallidotomy technique introducing a new target situated more anteriorly to the classic Laitinen´s pallidotomy, in this way we obtain relief in the whole motor signs of Parkinson´s disease. We believe it is the result of the interruption of efferents fibers from pallidum to motor thalamus, and coagulation of the majority of somatomotor cells of the posteroventral pallidum.
The association between hypothalamic hamartoma and gelastic epilepsy has been described several years ago. This type of tumor, usually asymptomatic, when it is related to epilepsy, can cause intractable seizures and a particular type of laughter crises. A brief analysis of the clinical features and treatment is performed.

Pick’s disease is a nosological entity with frontal dementia, early cortical dementia with severe frontal lobe disturbances, absence of apraxia, and absence of gait disturbance at onset. This disorder is underdiagnosed in clinical practice. When specific criteria for the clinic, imaging and neuropathologic diagnosis including the presence of Pick bodies, are used, the diagnosis of Pick’s disease is achieved. However, taking into account that the definitive diagnosis of PD is achieved only with pathological study, in vivo diagnosis requires of the combination of neuroimaging techniques.
More than 100 years ago, Arnold Pick described several patients who presented with progressive behavioral changes (apragmatism, outbursts of rage, and later stages, mutism) and who, at autopsy, had characteristic frontal or temporal lobar atrophy [1]. Alloys Alzheimer histologically characterized the disorder when he described “argentophylic globes” in the cytoplasm of neurons and the presence of ballooned neurons and spongy cortical wasting in the absence of neurofibrillary tangles or plaques [2]. Pick’s disease is considered a relatively rare neurodegenerative disorder, affecting subjects in their 60s with the progressive development of frontal lobe type features (e.g., difficulty planning, reasoning, abnormal social behavior), language disturbances (decreased fluency followed by echolalia, mutism), later followed by memory and gait abnormalities and occasional parkinsonism [3]. In autopsy studies of progressive dementia, only about 5% are due to PD. The underlying cause is not know, but there does appear to be a hereditary component, with clear autosomal dominant transmission in some families. The disease usually progresses inexorably over 2 to 5 years to death. At the present time there is no specific treatment available [4]. We report our findings in a patient with the purpose of to attract attention about this entity with the aim to avoid unnecessary, expensive and dangerous treatment when this kind of patients received a wrong diagnosis.
The number of hours of sleep, approximately 8, is an average that varies little from one culture to another. However, there are individual differences for this variable, which has permitted the establishment of certain sleep patterns. Many studies have focused on the relationship between psychological variables and sleep patterns, which have produced contradictory results. The purpose of the present investigation is to evaluate the extent of dimensions of extraverted and neurotic personalities and state-trait anxiety levels in women with different sleep patterns. In a sample of 300 young healthy adults, 34 women were selected, 17 women showed a long sleep pattern, 9 showed an intermediate sleep pattern and 8 showed a short sleep pattern (age X = 20.29 SD = 1.55). The results indicate that there are no significant statistical differences between psychological variables and sleep patterns, which concludes that there exists no relation between sleep duration and personality and anxiety factors.
