Epidural blood patching in an anticoagulated patient with intracranial hypotension.

A middle-aged man had classical clinical and radiographical features of spontaneous intracranial hypotension, refractory to conservative management. His medical history included antiphospholipid syndrome, autoimmune thrombocytopenia and recurrent thrombotic events. To reduce his risk from epidural blood patching, we stopped his anticoagulation, but he developed thrombosis.

Early intervention and neurodevelopmental outcome of infants with posthemorrhagic hydrocephalus: A case series and literature review.

Objective: Intraventricular hemorrhage (IVH) is the most common central nervous system pathology in preterm infants. No consensus has been reached over the best indication for intervention in patients with posthemorrhagic hydrocephalus (PHH). The authors present the neurological outcome of infants with IVH and an early treatment approach, defined as an intervention when ventricular dilation is less than 4-mm over the 97th-percentile of Levene's index.

Spontaneous intracranial hypotension: key features for a frequently misdiagnosed disorder.

Spontaneous intracranial hypotension (SIH) is a rare neurological condition caused by low cerebrospinal fluid (CSF) volume, most commonly due to a CSF leak. The most common presenting symptom is an orthostatic headache, but some patients may present with atypical neurological manifestations such as cranial nerve palsies, an altered mental status, and movement disorders, which complicate the clinical diagnosis. Therefore, the diagnosis is based on the combination of clinical signs and symptoms, neuroimaging, and/or a low cerebrospinal fluid pressure.

Intraventricular hemorrhage and posthemorrhagic hydrocephalus in preterm infants: diagnosis, classification, and treatment options.

Purpose: Intraventricular hemorrhage is the most important adverse neurologic event for preterm and very low weight birth infants in the neonatal period. This pathology can lead to various delays in motor, language, and cognition development. The aim of this article is to give an overview of the knowledge in diagnosis, classification, and treatment options of this pathology.

Impact of skull base development on endonasal endoscopic surgical corridors.

Object: Scarce morphometric data exist on the developing skull base as a corridor for endonasal endoscopic approaches (EEAs). Furthermore, the impact of skull base lesions on its development has not been assessed. The authors describe a novel set of anatomical parameters characterizing the developmental process as well as the utility of these parameters in preoperative planning and a feasibility assessment of EEAs for neurosurgical treatment of skull base lesions in children.

Endoscopic balloon dilation as an adjunct to extended endoscopic approaches to the skull base.

Cholesterol granulomas (CGs) are benign, expanding cystic lesions surrounded by a thick fibrous capsule and filled with fluid, formed by the degradation of blood elements. The goal of surgery is to open the granuloma widely, creating a well-drained cavity. The endonasal endoscopic approach for this extradural lesion is a minimal access method for surgical removal or fenestration.

Gasket seal closure for extended endonasal endoscopic skull base surgery: efficacy in a large case series.

Objective: To assess long-term efficacy of the gasket seal, a method for watertight closure of the cranial base using autologous fascia lata held in place by a rigid buttress, in a large case series.

Methods: A prospectively acquired database of all endonasal endoscopic surgeries performed over a 5-year period at Weill Cornell Medical College starting in September 2005 was reviewed.

Results: The gasket seal was used in 46 consecutive patients.

Use of a side-cutting aspiration device for resection of tumors during endoscopic endonasal approaches.

Object: Accessing intra- and extradural tumors via an endonasal approach requires working safely in a relatively narrow area with unobstructed visibility. The authors describe their experience to highlight the utility of a side-cutting aspiration device for endoscopic endonasal resection of skull base tumors.

Methods: The authors used this device in 13 nonconsecutive endoscopic endonasal procedures for different skull base tumors (8 pituitary macroadenomas, 2 craniopharyngiomas, 1 chordoma, 1 recurrent ependymoma, and 1 lymphoma).

A look at Mayan artificial cranial deformation practices: morphological and cultural aspects.

Induced deformation of the cranial vault is one form of permanent alteration of the body that has been performed by human beings from the beginning of history as a way of differentiating from others. These procedures have been observed in different cultures, but were particularly widespread in Mesoamerica. The authors examined and reviewed the historical and anthropological literature of intentional deformation practices in Mayan culture.

Choreoacanthocytosis in a Mexican family.

Background: Choreoacanthocytosis (CHAC) (Online Mendelian Inheritance in Man accession No. 200150) is a hereditary neurodegenerative syndrome characterized by movement disorders, cognitive decline, myopathy, behavioral changes, and acanthocytosis and is caused by mutations in the VPS13A gene.

Objective: To describe the cases of 2 Mexican women with clinical and molecular characteristics compatible with CHAC.

[Linear scleroderma en coup de sabre: neurological symptoms, images and review].

Introduction: 'Sword stroke' linear scleroderma, which is better known as linear scleroderma en coup de sabre (LSCS), is a rare disease with an uncertain causation that is characterised by progressive craniofacial focal atrophy and is, at least in part, different from Parry-Romberg syndrome (PRS).

Case Reports: Here, we report on the cases of 3 patients with LSCS (2 females and 1 male, with a mean age of 40 years). The main neurological symptoms were headache and seizures.

[Intracerebral haemorrhage in a referral hospital in the central-western region of Mexico].

Introduction: Intracerebral haemorrhage (ICH) has received little attention in studies in Mexico. Isolated reports talk of high frequency, its importance as a disorder among young people, its being mainly located in the lobar regions and a high rate of recurrence.

Aims: The objective of this study was to characterise the clinical, radiological, therapeutic and prognostic spectrum of ICH in a general hospital in the central-western region of Mexico.
