An allopatric population of big-eared climbing rats ( Ototylomys ) from the Northern Highlands of Chiapas, Mexico, is described as a new species. The new taxon is part of a unique montane rainforest community that includes several other endemic species in the limited geographic range between the Río Grijalva and the Central Depression of Chiapas. Several cranial, external, and molecular characters distinguish this new species of big-eared climbing rat from its more widely distributed congener, Ototylomys phyllotis ...

INTRODUCTION: Skull base metastases (SBM) are an infrequent and late type of cancer progression that are associated to poor prognosis. Its clinical manifestations may be grouped in five clinical syndromes and radiotherapy is its more frequent treatment. Because of the improvement in imaging tests and the close follow up of cancer patients, SBM can be diagnosed incidentally. In this group the best option of treatment has not been established. AIM: To analyze the clinical features and outcomes of patients with SBM diagnosed incidentally...

Most Chinese characters are composed of a semantic radical on the left and a phonetic radical on the right. The semantic radical provides the semantic information; the phonetic radical provides information concerning the pronunciation of the whole character. The pseudo-characters in the study consisted of different sub-lexical parts of real Chinese characters and consequently they also had the semantic radical and the phonetic radical. But they were not readable and had no actual meaning. In order to investigate the spatiotemporal cortical activation patterns underlying the orthographic, phonological and semantic processing of Chinese characters, we used event-related brain potentials (ERPs) to explore the processing of Chinese characters and pseudo-characters when 14 healthy Chinese college students viewed the characters passively...

CLINICAL CASE: Craneal sinuses stenosis can appear in patients with idiopathic intracranial hypertension. Neuroimaging techniques revealed a right transverse sinus stenosis. As the pressure gradient between both sides of the stenosis was small and response to conservative treatment good, angioplasty was not indicated. DISCUSSION: Lateral sinus stenosis in patients with idiopathic intracranial hypertension is prevalent. It is not clear whether these stenoses are the origin of, or secondary to, cerebrospinal fluid pressure increases...

Schwannomas are tumors rarely localized in the retroperitoneum, generally appear in craneal as well as periferic nerves. Seldom cases the diagnosis is preoperatively made just because imaging is very poor in this field. MRI is proven to be the diagnostic method. Radical surgical ressection is standarized treatment. We document a case of a benign retroperitoneal schwannoma where we explain the laparoscopic ressection of this kind of tumors for first time.

INTRODUCTION: Abuse of cocaine and other sympathomimetic drugs has been reported as a significant risk factor for stroke. The physiopathologic mechanisms implicated are multifactorial. Chronic cocaine use leads to extensive destruction of osteocartilaginous structures of nose, sinuses and palate. CASE REPORT: We report the case of a 56 years-old woman with hypertension and smoke abuse who was admitted with a pontine paramedian infarction. Cranial resonance findings of midline destructive lesions lead to the suspicion of chronic cocaine consumption...

The arterioveinous dural malformation (MAVD) is a rare entity between the vascular craneal anomalies with a not well nown ethiology and variability in treatments. We present eleven cases of MAVDs, between them five presented tinnitus as symptom of aparition. The importance of this pathology makes necessary to discard it before a patient consulting because of pulsaltil tinnitus with normal otoscopy.

The procedure of hygiene pre and post surgical of the patient of neurosurgery in the University Hospital of Bellvitge, initiated in 1995, guarantees the correct preparation of the surgical zone, the frequency and accomplishment of the therapeutic washing reduces the risk of infection of the wound and maintains the integrity of the hairy leather. It diminishes the presurgical anguish of the patient and improves the adaptation to the corporal changes by surgery.

We present the case of a 56 years old female controlled in our ENT Department because of right sudden hearing loss, tinnitus and vertigo. The endoscopic exam was normal. Audiogram showed a severe neurosensorial hypoacusia and PEATC confirmed the so called hypoacusia suggesting a retrocochlear origin of it. As imaging tests an otic-craneal CT and IRM were asked for, which informed of the presence of a cystic lesion versus polyp in sphenoidal sinus of 15 x 10 mm without other alterations or significant pathology...

The Horton's disease is a generalized vascular affectation, characterized by a giant cell arteritis. Medium and small caliber arteries are the most frequently affected, mainly of the craneal vascular territory, in particular the collateral branches of the external carotid, and artery in special the superficial temporal artery. We present a case of lingual necrosis as debut of the Horton's disease that has been diagnosed and treated in our ENT Department.

The pubic joint of male and female rats was studied at the light- and electron microscopical levels using methods that selectively disclose the extracellular matrix fibres and glycosaminoglycans. The interpubic tissue showed no difference between sexes (including pregnant and intrapartum females). The medial ends of the pubic bones were covered by articular caps of hyaline cartilage that blended in the midline. The whole articular cartilage was covered dorsally and ventrally (as well as craneally and caudally) by a typical perichondrium...

Neuronal migration disorders represent a group of congenital nervous system malformations that affect the process whereby millions of neuroectodermic cells move from germinal matrix to the loci, where they will reside for life. They produce important changes in cytoarchitecture, lamination and normal neuronal physiology, particularly in cerebral cortex. These disorders appear as sporadic cases, genetically determined or caused by external agents as infections, intoxications and radiations, etc. The better identified nosological entities include: schizencephaly, lissencephaly, pachygyria, polymicrogyria, neuronal heterotopias and agenesis of corpus callosum...

A major issue in developmental biology is to determine how time and position-restricted instructions are signaled and received during morphogenesis of different phenotypes, of which tooth, Meckel's cartilage and tongue formation are classical examples. It is now evident that a hierarchy of growth factors and their downstream transcription factors regulate the timing, sequence and position of cells and tissues in forming different phenotypes during embryogenesis. Here we report the development of an early mandibular organ culture model...
