Dominant Occipital Sinus: A Rare Anatomical Variant With Potentially Catastrophic Consequences if Unrecognized Preoperatively.

The occipital sinus is often thought of as a redundant vestigial structure in adults. However, in rare cases, it can form the dominant route of intracerebral venous drainage, with a risk of significant surgical morbidity if unrecognised. We present an illustrative case describing this anatomical variant and tailoring of a midline suboccipital craniotomy to allow resection of a fourth ventricular epidermoid tumour with preservation of a dominant occipital sinus, and a review of the published literature.

All-Cause and Cause-Specific Mortality in Children With Congenital Zika Syndrome in Brazil.

Importance: Congenital Zika syndrome (CZS) can lead to a range of developmental and neurological issues, which increases the risk of early death. However, the all-cause and cause-specific mortality in children with CZS in the first 5 years of life remain unknown.

Objective: To compare the hazard of all-cause and cause-specific mortality before age 5 years among children with and without CZS in Brazil.

Stress assessment instruments for hospitalized preterm newborns: scoping review.

Background: The highly technological environment existing in intensive care units, essential for the survival of the newborn, contributes with a potentially devastating and traumatic effect, especially in preterm newborns and in their future lives, due to the early and frequent exposure to multiple stressors. The preterm newborn must be observed in a systematic and structured way, before, during and after any intervention, aiming at the correct assessment and interpretation of his behaviour and signs of stress, and at the timely planning of interventions that minimize and prevent stress. The objective of this review is to identify and map the instruments for assessing stress in preterm newborns admitted to neonatal units in scientific evidence.

Evaluation of adrenal tumors and analysis of the metabolic profile of patients with incidentaloma.

Introduction: Advances in imaging methods have led to an increasingly frequent diagnosis of adrenal gland lesions as incidental findings. Despite progress in this field, there is still limited information regarding the epidemiology of the clinical and metabolic profile of patients with adrenal incidentaloma (AI). The objective is analyze the epidemiology of adrenal tumors at Gaffrée e Guinle University Hospital (HUGG) and compare it with data from the literature.

Evaluation of Healthcare Outcomes of Patients Treated with 3D-Printed-Titanium and PEEK Cages During Fusion Procedures in the Lumbar Spine.

Purpose: The objective of this observational, real-world study was to describe reoperation, revision, index healthcare utilization and hospital costs among patients treated with PEEK (polyetheretherketone) or 3D-printed-titanium cages during lumbar/lumbosacral posterior fusion procedures, either TLIF (transforaminal lumbar interbody fusion) or PLIF (posterior lumbar interbody fusion). Statistical comparisons were not conducted.

Methods: This was a descriptive, retrospective, observational study.
