Pediatric trauma during the COVID-19 lockdown: caregiver abuse and self-harm in a vulnerable population.

Purpose: This retrospective cohort study explores the impact of the COVID-19 pandemic on pediatric trauma cases in Singapore's National University Hospital from January 2015 to July 2021. The pandemic prompted unprecedented measures, altering societal dynamics. The study hypothesizes a reduction in major trauma incidents during the pandemic period.

Biomechanical implications of unilateral facetectomy, unilateral facetectomy plus partial contralateral facetectomy, and complete bilateral facetectomy in minimally invasive transforaminal interbody fusion.

Objective: Minimally invasive transforaminal interbody fusion techniques vary among surgeons. One decision point is whether to perform a unilateral facetectomy (UF), a unilateral facetectomy plus partial contralateral facetectomy (UF/PF), or a complete bilateral facetectomy (CBF). The authors therefore compared the biomechanical benefits of all 3 types of facetectomies to determine which approach produces improved biomechanical outcomes.

Tailoring selection of transforaminal interbody spacers based on biomechanical characteristics and surgical goals: evaluation of an expandable spacer.

Objective: Transforaminal lumbar interbody fusion (TLIF) is commonly used for lumbar fusion, such as for foraminal decompression, stabilization, and improving segmental lordosis. Although many options exist, surgical success is contingent on matching design strengths with surgical goals. The goal in the present study was to investigate the effects of an expandable interbody spacer and 2 traditional static spacer designs in terms of stability, compressive stiffness, foraminal height, and segmental lordosis.

Adrenal cancer in neurofibromatosis type 1: case report and DNA analysis.

Unlabelled: Adrenal cortical carcinoma (ACC) has previously only been reported in eight patients with type 1 neurofibromatosis (NF1). There has not been any clear evidence of a causal association between NF1 gene mutations and adrenocortical malignancy development. We report the case of a 49-year-old female, with no family history of endocrinopathy, who was diagnosed with ACC on the background of NF1, due to a novel germline frame shift mutation (c.

A boy with arachnoid cyst, a fall, and temporary and reversible visual impairment.

Background: Temporal arachnoid cysts have been shown to interfere with the function of nervous structures, both cerebral cortex and cranial nerves.

Methods And Results: In this case report we describe a boy with a left temporal arachnoid cyst with a sudden onset of visual impairment 4 days after a mild trauma to the head. A perimetry test revealed a complete nasal hemianopia of the left eye, which normalized rapidly after an emergency craniotomy with cyst fenestration 3 hours after the patient experienced the reduced vision.

Primary intracranial myxoma of the parietal region. Illustrated case report.

An extremely rare case of primary intracranial myxoma mimicking an intraaxial parenchymal tumour is reported. A 25 year old male presented with complaints of headache and right sided hemiparesis. A gross total resection of the tumour was achieved.

Hemangioblastoma of the filum terminale.

A 52-year-old man presented with low backache, paraesthesiae and spasticity of both lower limbs. He had urinary retention and constipation. Investigations revealed a vascular intradural cauda equina-conus tumor.

Spontaneous cerebrospinal fluid rhinorrhea following excision of a massive torcular meningioma.

A massive supratentorial torcular meningioma was completely resected in a 50-year-old woman. On the tenth postoperative day she presented with spontaneous cerebrospinal fluid (CSF) rhinorrhea. The site of the CSF leak was through the region of the cribriform plate, remote from the site of surgery.

Cerebellar oligodendroglioma in a young adult.

A rare case of an oligodendroglioma of the cerebellum in an 18-year-old male is presented. Radical surgical excision and craniospinal radiotherapy appear to be the treatment options for these potentially malignant lesions.

Segmental costovertebral malformation associated with lipomyelomeningocoele.

We describe 2 patients with segmental costovertebral malformation, a form of spondylocostal dysostosis, associated with tethering of the conus to a lipomyelomeningocoele. Such an association is rare. In both these patients the defects occurred sporadically.

Ossified ligamentum flavum of the atlantoaxial region.

A 30-year-old male presented complaining of a six-month history of progressive weakness and paraesthesia in all four limbs. Symptoms occurred following moderately severe neck trauma. Investigations revealed ossification of the ligamentum flavum (OLF) between the atlas and axis, with marked cord compression.
