Spontaneous regression of paediatric pituitary lesions-report of 2 cases and literature review.

Objective: Pituitary lesions are rare in the pediatric population. They consist of a heterogenous group of neoplasms including pituitary adenomas (PA) and Rathke cleft cysts (RCC). Their natural history, management strategies, and long-term outcomes are mostly extrapolated from adult experience.

Pleomorphic xanthoastrocytoma with NTRK fusion presenting as spontaneous intracranial hemorrhage-case report and literature review.

Background: Pleomorphic xanthoastrocytoma (PXA) is a rare brain tumor that accounts for <1% of all gliomas. An in-depth understanding of PXA's molecular makeup remains a work in progress due to its limited numbers globally. Separately, spontaneous intracranial hemorrhage (pICH) is an uncommon but potentially devastating emergency in young children, often caused by vascular malformations or underlying hematological conditions.

Complex lumbosacral spinal cord lipomas: A longitudinal study on outcomes from a Singapore children's hospital.

Background: Total/near-total resection (TR/NTR) of complex lumbosacral lipomas (CSL) is reported to be associated with better long-term functional outcomes and lower symptomatic re-tethering rates. We report our institutional experience for CSL resection in affected children.

Methods: This is a single-institution, retrospective study.

Selective dorsal rhizotomy using a 3D high definition exoscope.

Selective dorsal rhizotomy (SDR) is an established neurosurgical technique for children with spastic diplegia secondary to cerebral palsy. Meticulous intraoperative testing of individual nerve roots with electromyography in tandem with the on-site neurorehabilitation team is recommended for good clinical outcomes. The standard approach requires the neurosurgeons to spend extended time under the traditional operating microscope.

Spontaneous regression of migrated ventriculoperitoneal shunt catheter from scrotum to peritoneum: a case-based review.

Objective: The incidence of scrotal migration of a ventriculoperitoneal shunt (VPS) catheter is rare and may lead to life-threatening visceral complications. Management requires prompt removal of the migrated portion of the shunt and closure of the scrotal sac. We report an interesting case of a young child who presented with asymptomatic unilateral swelling of his scrotum secondary to a migrated VPS catheter.

Cerebrospinal fluid shunt malfunctions: A reflective review.

Purpose: Pediatric hydrocephalus is a common and challenging condition. To date, the ventriculoperitoneal shunt (VPS) is still the main lifesaving treatment option. Nonetheless, it remains imperfect and is associated with multiple short- and long-term complications.

Pediatric Primary Intracranial Malignant Melanoma: Case Report and Literature Review.

Introduction: Primary intracranial malignant melanoma (PIMM) is an extremely rare primary brain tumor with most cases diagnosed in adults. To date, there are only a few cases reported in the pediatric population. Owing to its infrequency, there are no established guidelines to treat this aggressive neoplasm.

Paediatric ventriculoperitoneal shunt failures: 12-year experience from a Singapore children's hospital.

Purpose: Cerebrospinal fluid (CSF) shunt failures in children are devastating. The primary aims of this study are to, firstly, review our institutional series of ventriculoperitoneal shunt (VPS) insertions and identify factors associated with shunt failure.

Methods: This is a single-institution, retrospective study conducted over a 12-year period.

Withdrawal notice to Spinal dysraphism-perspectives from a Southeast Asian paediatric neurosurgical unit: WNEU, 173 (2023) 20134.

Generation and multi-dimensional profiling of a childhood cancer cell line atlas defines new therapeutic opportunities.

Pediatric solid and central nervous system tumors are the leading cause of cancer-related death among children. Identifying new targeted therapies necessitates the use of pediatric cancer models that faithfully recapitulate the patient's disease. However, the generation and characterization of pediatric cancer models has significantly lagged behind adult cancers, underscoring the urgent need to develop pediatric-focused cell line resources.

Intraoperative Fluorescein Sodium in Pediatric Neurosurgery: A Preliminary Case Series from a Singapore Children's Hospital.

(1) Background: Fluorescein sodium (Na-Fl) has been described as a safe and useful neurosurgical adjunct in adult neurooncology. However, its use has yet to be fully established in children. We designed a study to investigate the use of intraoperative Na-Fl in pediatric brain tumor surgery.

Tethered cord secondary to focal nondisjunction of the primary neural tube: experience from a Singapore children's hospital.

Purpose: Tethered cord due to focal nondisjunction of primary neuralisation (FNPN) is a rare form of spinal dysraphism. We present our institutional experience in managing children diagnosed with FNPN.

Materials And Methods: This is a single institution, retrospective study approved by the hospital ethics board.

Fibrofatty filum terminale: long-term outcomes from a Singapore children's hospital.

Objective: The role of prophylactic detethering a fibrofatty filum terminale (FFT) remains equivocal. Furthermore, long-term studies focusing on urological outcomes are sparse. The aims of this study were to present an institutional experience on the perioperative and long-term outcomes of FFT surgery and to assess for factors that contribute to postoperative clean intermittent catheterization (CIC).

Decompressive surgery in abusive head injury: Experience from a Singapore children's hospital and a review of literature.

Purpose: Abusive head trauma (AHT) is a major cause of morbidity and mortality in children. Studies on pediatric head injury observe that AHT patients often have a higher incidence of malignant cerebral oedema and, overall, worse prognosis. There are limited studies with a focus on the outcome of decompressive surgery in children with AHT.

Outcomes of intracranial non-germinomatous germ cell tumors: a retrospective Asian multinational study on treatment strategies and prognostic factors.

Purpose: Non-germinomatous germ cell tumors (NGGCTs) are rare pediatric conditions. This multicenter study using Asian multinational patient data investigated treatment outcomes and prognostic factors for NGGCTs.

Methods: Medical records of 251 patients with NGGCTs treated from 1995 to 2015 were retrospectively analyzed from participating centers in Asian countries (Korea, Taiwan, Singapore, and Japan).

Abusive head injury in the very young: outcomes from a Singapore children's hospital.

Purpose: Abusive head trauma (AHT) is a serious problem in children. The aims of this study are to identify risk factors that correlate with outcomes for those requiring neurosurgical intervention for very young children with AHT, assessment of variables associated with outcomes, and corroboration of our results with literature.

Methods: This is an ethics-approved, retrospective study.

Paediatric brain tumours in Singapore: A 15-year epidemiological and outcome study.

Paediatric brain tumours (PBTs) are the most common solid tumours in children. Previous publications reflect variations in incidence rates and frequency of histological types in different global populations. However, there are limited studies on the epidemiology of PBTs in Singapore.

Monomodality versus Combined Therapy in Optic Pathway Gliomas-20-Year Experience from a Singapore Children's Hospital.

Introduction: The treatment of pediatric optic pathway gliomas (OPG) is challenging. At present, most centers provide individualized treatment to maximize progression free survival (PFS) and minimize morbidity. We aim to report our experience in the management of pediatric OPG, and investigate factors associated with an increased duration of remission after treatment.
