Cluster headache: an update on clinical features, epidemiology, pathophysiology, diagnosis, and treatment.

Cluster headache (CH) is one of the worst primary headaches that remain underdiagnosed and inappropriately treated. There are recent advances in the understanding of this disease and available treatments. This paper aims to review CH's recent clinical and pathophysiological findings, diagnosis, and treatment.

Brain vascular lesions: a clinicopathologic, immunohistochemistry, and ultrastructural approach.

Brain vascular malformations are relatively common lesions that cause serious neurologic disability or death in a significant proportion of individuals bearing them. The purpose of this study was to analyze the clinicopathologic and immunohistochemistry these lesions, looking for common antibodies expressed such as CD31, CD34, CD15, factor VIII, nestin, vimentin, vascular endothelial grow factor (VEGF), vascular endothelial grow factor receptor-2 (VEGF-R2), glial fibrillar acidic protien (GFAP), and fibroblastic grow factor β (β-FGF) and ultrastructure in endothelial cells as well as in vessel walls. Fifty cases of vascular lesions were included in this study: 29 (58%) of them were arteriovenous malformations and 21 (52%) were brain cavernomas.

Coexistence between meningioma and tuberculosis: case report.

Intracranial tuberculoma generally presents as either solitary or multiple lesions in the brain parenchyma. These are characterized by a ring-enhancing area on either computerized tomography scans or magnetic resonance images. A 66 year-old female with a history of breast carcinoma at 41 years, treated with radical mastectomy and radio and chemotherapy, and rheumatoid arthritis, treated in the last 10 years, presented two months ago with occipital headache, nausea, cerebellar syndrome, alterations of speech, and memory loss.

Chordoid meningioma: a report of ten cases.

Chordoid meningioma is a rare variant of meningioma with histological features resembling those of chordoma. This tumor has a great risk of recurrence and aggressive growth (WHO grade II). This study was done to document the clinical and pathological features of ten patients with chordoid meningioma who submitted to surgery at the National Institute of Neurology and Neurosurgery in Mexico City.

[Type I spinal atrophy (Werdnig-Hoffman disease). Case report].

Background: We report a case of type I spinal muscular atrophy (SMA), also known as Werdnig-Hoffmann disease.

Methods: This was a descriptive case report. The patient was in the pediatric intensive care unit of a medical center.

[Characterization of children with cleft lip or palate].

We reviewed 237 cases of children with cleft lip and/or palate from the Department of Human Communication. Sociodemographic data, diagnoses, surgeries, family structure, family problems reported, psychological evaluation, conduct report, disabilities and emotional indicators were all considered. All these categories are reviewed from a systemic perspective in which each is directly inter-related and directly responsible (along with other factors that must be researched) for the outcome and well being of the patient.

[Perioperative lesions in lower extremity peripheral nerves].

Objective: To review the actual concepts concerning perioperative nerve injuries during surgical or anesthetic procedures.

Material And Methods: A summary of published medical literature from Medline search files and published reviews. CONFLICT IF INTEREST: We have not conflicts of interest.
