Background: Nonlethal neural tube defects are developmental malformations with complex pathogenesis usually manifested at birth or in childhood.

Case Description: We report the case of a 61-year-old woman without significant previous clinical history presenting for neck pain and stiffness. An extensive workup detected multiple lytic lesions within the occipital bone and cervical vertebrae, suspicious for multiple myeloma or metastatic disease. Surgical resection of the occipital bone lesions revealed ectopic cerebellar tissue, some containing folia with mature cortical lamination, and no evidence of malignancy.

Conclusions: To our knowledge, this study describes the oldest individual presenting with ectopic cerebellar tissue and the only instance in which oncologic workup for malignancy was carried out prior to resection. It also proposes surgical resection as a diagnostic and curative approach for this complex basicranium and neural developmental defect, and discusses retinoic acid toxicity as a possible cause of its occurrence.

Objectives: To analyze the risk factors for developing dysphagia after occipitocervical fusion (OCF) and investigate possible mechanisms and prognosis.

Methods: The case data of 43 patients who underwent OCF were retrospectively reviewed. Patients were divided into group A (dysphagia group) and group B (non-dysphagia group) based on Bazaz scoring criteria.

[The value of studying the cervical spine in craniofacial asymmetries].

Orthod Fr

5 rue Georges Meynieu, 44300 Nantes, France

Introduction: The relationship between facial asymmetry and cervical anomaly is rarely mentioned in the diagnosis of dento-maxillo-facial orthopaedics. It is regrettable that the study of the cervical spine is often ignored in the etio-pathogenesis of these dysmorphoses, particularly in cases of facial asymmetry.

Objective: The aim is twofold: to encourage orthodontists and maxillofacial surgeons to make a systematic study of the cervical spine in craniofacial dysmorphoses and in particular craniofacial asymmetries, without claiming that they are becoming specialists in cervical spine pathology, and to introduce the necessary training in malformations of this anatomical region as part of the orthodontist specialisation curriculum.

Studies of modeling processes have provided important insights in human evolutionary discipline. Most of these studies are based on facial bones and in much lesser extent on other bones such as those from the cranial vault. Thus, this study fills a gap in research by examining occipital bone modeling in subadults, adding individuals under 2 years old and expanding the sample size available to date.

Craniosynostosis, a condition marked by the premature fusion of one or more cranial sutures, exhibits diverse phenotypes. This study aims to advance the understanding of these phenotypes beyond the conventional 2-dimensional analysis by focusing on identifying indicators of increased intracranial pressure (ICP) such as bony thinning or irregularities in skull morphology. A retrospective review was conducted for all pediatric patients with midline craniosynostosis who presented to our tertiary academic center for evaluation.

Intra-Individual Stable Isotope Variation Tracks Brazilian Contemporary Dietary and Nutritional Transition.

Introduction: Contemporary dietary and nutritional transitions are commonplace, but difficult to study directly. In Brazil, and Latin America, this generalized process, leading to current obesity and malnutrition problems, started more than four decades ago. Although body weight and food availability are used to measure changes, not much information on food consumption and nutrition exist.
