Can Craniosynostosis be Diagnosed on Physical Examination? A Retrospective Review.

Craniosynostosis is a developmental craniofacial defect in which one or more sutures of the skull fuse together prematurely. Uncorrected craniosynostosis may have serious complications including elevated intracranial pressure, developmental delay, and blindness. Proper diagnosis of craniosynostosis requires a physical examination of the head with assessment for symmetry and palpation of sutures for prominence. Often, if craniosynostosis is suspected, computed tomography (CT) imaging will be obtained. Recent literature has posited that this is unnecessary. This study aims to address whether physical examination alone is sufficient for the diagnosis and treatment planning of single suture craniosynostosis. Between 2015 and 2022, the Divisions of Pediatric Neurosurgery and Pediatric Plastic Surgery at UTHealth Houston evaluated 140 children under 36 months of age with suspected craniosynostosis by physical examination and subsequently ordered CT imaging for preoperative planning. Twenty-three patients received a clinical diagnosis of multi-sutural or syndromic craniosynostosis that was confirmed by CT. One hundred seventeen patients were diagnosed with single suture craniosynostosis on clinical examination and follow-up CT confirmed suture fusion in 109 (93.2%) patients and identified intracranial anomalies in 7 (6.0%) patients. These patients underwent surgical correction. Eight (6.8%) patients showed no evidence of craniosynostosis on CT imaging. Treatment for patients without fused sutures included molding helmets and observation alone. This evidence suggests that physical examination alone may be inadequate to accurately diagnose single suture synostosis, and surgery without preoperative CT evaluation could lead to unindicated procedures.

Thirty-two nails injected into the head: An operative report and review of the literature.

Background: Self-inflicted nail gun injuries are a rare phenomenon that can result in traumatic damage. The velocity of the nail is generally fast enough to penetrate the skull. However, the extent of damage depends on the exact angle and structures of the brain encountered by the nails. Case Description: A 55-year-old male presented with 32 nails in the head and was found down. Initially, the patient presented with localization but had to be intubated soon after due to declining condition. This report describes the operative technique for safe removal of all nails, separated into six categories based on location and structures of the brain encountered. A review of literature revealed potential complications such as hemorrhage and infections and how to protect against these undesired effects. Conclusion: Self-inflicted nail gun head injuries are an uncommon form of traumatic head injury. Some important tools that helped prevent our patient from developing major complications included stereotactic navigation, antibiotic prophylaxis, and angiography to carefully monitor for vascular injuries.

Venous Sinus Stenting for Low Pressure Gradient Stenoses in Idiopathic Intracranial Hypertension.

BACKGROUND: Medically refractory idiopathic intracranial hypertension (IIH) is frequently treated with venous sinus stenosis stenting with high success rates. Patient selection has been driven almost exclusively by identification of supraphysiological venous pressure gradients across stenotic regions based on theoretical assessment of likelihood of response. OBJECTIVE: To explore the possibility of benefit in low venous pressure gradient patients. METHODS: Using a single-center, prospectively maintained registry of patients with IIH undergoing venous stenting, we defined treatment groups by gradient pressures of ≤4, 5 to 8, and >8 mmHg based on the most frequently previously published thresholds for stenting. Baseline demographics, clinical, and neuro-ophthalmological outcomes (including optical coherence tomography and Humphrey visual fields) were compared. RESULTS: Among 53 patients, the mean age was 32 years and 70% female with a mean body mass index was 36 kg/m 2 . Baseline characteristics were similar between groups. The mean change in lumbar puncture opening pressure at 6 months poststenting was similar between the 3 groups (≤4, 5-8, and >8 mmHg; 13.4, 12.9, and 12.4 cmH 2 O, P = .47). Papilledema improvement was observed across groups at 6 months (100, 93, and 86, P = .7) as were all clinical symptoms. The mean changes in optical coherence tomography retinal nerve fiber layer (-30, -54, and -104, P = .5) and mean deviation in Humphrey visual fields (60, 64, and 67, P = .5) at 6 weeks were not significantly different. CONCLUSION: Patients with IH with low venous pressure gradient venous sinus stenosis seem to benefit equally from venous stenting compared with their higher gradient counterparts. Re-evaluation of our restrictive criteria for this potentially vision sparing intervention is warranted. Future prospective confirmatory studies are needed.

Choroid plexus cauterization to treat inadequate abdominal cerebrospinal fluid absorption: case report.

INTRODUCTION: Inadequate absorption of cerebrospinal fluid (CSF) in the setting of high CSF production is a relatively rare cause of shunt malfunction. CASE REPORT: We present the unique case of a 3-year-old boy who developed sterile ascites and abdominal distension in a delayed fashion after shunt placement. The shunt was externalized, and the patient was noted to have high CSF output. Bilateral choroid plexus cauterization resulted in a significant decrease in CSF production and enabled the shunt to be re-inserted into the abdomen.

Factors Associated With Pregnancy and Perinatal Outcomes in Female Neurosurgeons: A Cross-Sectional Study.

Neurosurgery is male dominated with women representing only 12% of residents and 5% of practicing neurosurgeons. The conflicting demands of training versus pregnancy and motherhood are significant deterrents to women entering the field. We examined pregnancy incidence and timing, perinatal complications, and the perceived career impact of motherhood on female neurosurgeons using an anonymous survey of 643 training, practicing, and retired female neurosurgeons from the United States. Among 260 respondents, 50.8% (132/260) reported pregnancies, with an average age at first pregnancy that was significantly higher than the national average (32.1 vs 26.3 yr). In all, 40.1% (53/132) of respondents reported perinatal complications in at least one of their pregnancies. Only 25% (33/132) of respondents noted designated program maternity allowances. The most significant challenges associated with being a mother and neurosurgeon reported were issues relating to work/life balance, "mommy guilt," and sleep deprivation. A majority of respondents, 70.1% (82/116), reported fear of backlash from co-residents, partners, and staff, as well as hindered career advancement related to childbearing. Female neurosurgeons face challenges surrounding family planning different from those faced by male practitioners. Higher perinatal and fetal complications, backlash from colleagues, and demanding workload are significant issues. Progress requires institutional support and mentorship for women to create a more diverse field of practitioners.

Atrioesophageal Fistula: Considerations for the neurological clinician.

Atrioesophageal fistula (AEF) is a rare complication of cardiac ablation for atrial fibrillation. It can present in many ways, but neurological signs and symptoms are common initial signs sometimes resulting in neurosurgeons and neurologists first evaluating patients with the condition. We present a case report of at 68-year-old female who presented with acute stroke symptoms and multifocal hemorrhages on MRI who was worked up through our neurosurgery department and diagnosed with AEF. This case highlights three clues to alert neurological clinicians to AEF as a possible diagnosis; clinical worsening of neurological symptoms in correlation to episodes of emesis, septic emboli on CT/MRI, and bacteremia caused by a gram positive oral or GI flora. If neurological clinicians encounter these red flags, an immediate CT of the chest and abdomen and consultation with cardiothoracic surgery may be life-saving.
