Acalvaria: a case report of a rare congenital malformation and a review of the literature.

Acalvaria is a rare congenital malformation characterized by the absence of bones and related muscles in a section of the skull. The number of reported cases in the literature is quite low, and it is generally considered a fatal malformation. We present a case of a newborn diagnosed with acalvaria malformation along with a review of the literature, emphasizing the importance of distinguishing this rare condition from malformations such as anencephaly, exencephaly and acrania. INTRODUCTION: The clinical landscape of acalvaria is scarcely populated, with the malformation often signifying a dire prognosis. Despite the embryological origin and pathogenesis remaining largely enigmatic, it has critical implications for the prenatal and postnatal therapeutic strategies. We investigate a case coupled with a comprehensive literary review to present a clearer clinical portrait and advance the alertness about this lethal anomaly among healthcare providers. DISCUSSION: The rarity of acalvaria constrains the establishment of a definitive incidence rate or a standardized treatment protocol. Varied associations with other neurological and systemic anomalies pose a significant ambiguity regarding its etiopathogenesis. Differential diagnosis remains intricate, relying on nuanced ultrasonographic examinations and an informed interpretation of embryological developments. CONCLUSION: Through our report of an acalvaria-affected newborn undetectable in prenatal ultrasound, we highlight the implications of rarity - the obstacle in uniform diagnosis and the resultant therapeutic challenge. The discussion fosters a need for heightened awareness and consolidating case reports to nurture clinical consensus. Furthermore, it underscores the necessity for multifaceted research efforts towards understanding etiology and optimizing treatment modalities.

Virtual reality hypnosis for needle-related procedural pain and fear management in children: a non-inferiority randomized trial.

Needle-related procedures can cause pain and fear in children and may lead to avoidance of future medical care. The aim of this study is to investigate whether virtual reality hypnosis (VRH) is non-inferior to medical hypnosis (MH) by a trained healthcare provider in reducing pain in children. This non-inferiority randomized trial was conducted at a teaching hospital in the Netherlands. Children aged 6 to 18 years were randomized to treatment with VRH or MH. The primary outcome was self-reported pain, using the Wong-Baker FACES Scale (WBFS) with the non-inferiority margin defined as a difference of 1.5 points. Secondary outcomes included observer-reported pain (Numeric Rating Scale), fear (scored by children and observers with the Children's Fear Scale), blood pressure, heart rate, treatment satisfaction, and adverse effects. We randomized 138 children to VRH or MH treatment and included 114 children in the analyses (VRH n = 60, MH n = 54). We found non-inferiority for VRH compared to MH on patient-reported pain (mean difference = - 0.17, 95%CI - 1.01;0.66). Secondary outcomes were comparable between VRH and MH groups. Both treatments scored high on patient satisfaction (VRH median = 9.0, MH median = 10.0, p = 0.512). CONCLUSION: VRH may be an effective and safe treatment option besides MH for reducing patient-reported pain in children during a needle-related procedure. VRH was non-inferior to MH in patient-reported fear and both treatments were comparable in terms of patient-reported fear, observer-reported pain and fear, physical distress, and patient satisfaction.

WHAT IS KNOWN: • Medical hypnosis is effective in reducing procedural distress in children during needle-related procedures. • Virtual reality (VR) is an audiovisual electronic device that guides users into an immersive three-dimensional environment. WHAT IS NEW: • This study shows that VR hypnosis is non-inferior to medical hypnosis in reducing pain and fear in children undergoing a needle-related procedure. • Both VR hypnosis and medical hypnosis were appreciated highly by children to distract them during needle-related procedures.
