Introduction: Children with spina bifida (SB) experience a reduced quality of life due to neurogenic bladder dysfunction and the risk of renal failure later in life. Pelvic floor rehabilitation (PFR) and transcutaneous electrical nerve stimulation (TENS) have gained prominence in recent years due to their positive effects in treating different types of bladder issues in both adults and children. Our study aims to investigate the effects of using these two methods together in children with SB and to delineate their potential value for clinical practice.

Background: Decreased bladder compliance is an important risk factor for upper urinary tract in children with neurogenic bladder dysfunction (NBD). Urodynamics is the gold standard in determining bladder compliance.

Objective: To investigate the relationship between low bladder compliance and urinary fibrosis markers in NBD.

Introduction: Tibial somatosensory evoked potentials (SEP) are used to identify the neurological status and tethered cord (TC) in patients with spina bifida (SB). Its significance in contributing to the interpretation of urodynamics to determine bladder status is unknown. This study aimed to determine the correlation between SEP and urodynamics in children with SB.

Article Synopsis
  • The study aimed to compare blood levels of vitamin B12, folic acid, riboflavin, and homocysteine in young keratoconus (KC) patients and healthy individuals.
  • Conducted at Eskişehir Osmangazi University, the study included 100 KC patients and 200 healthy controls, using blood tests and ophthalmologic evaluations to gather data.
  • While most nutrients showed no significant differences, riboflavin levels were significantly lower in KC patients, suggesting it may be a risk factor in developing the condition.

Purpose: Spina bifida (SB) is a congenital disorder caused by the incomplete fusion of the embryonic neural tube during spinal cord development. In this study, we used Spectral Domain Optic Coherence Tomography (SD-OCT) for retinal nerve fibre layer (RNFL) and ganglion cell complex (GCC) analyses and compared the results of healthy children and SB patients in a similar age group.

Methods: Our study was planned prospectively and conducted between June 2017 and July 2019.

Aim: To determine the clinical value of anocutaneous reflex (AR) in children with neurogenic bladder due to spina bifida (SB).

Material And Methods: Patients who were diagnosed with SB were prospectively evaluated; moreover, AR and bulbocavernous reflex were examined. Patients were divided into those with and without AR.

Objective: Myelomeningocele is the most severe and the most frequent form of spina bifida. Most of the myelomeningocele patients undergo operations in new-born age. In terms of life quality and rehabilitation, follow-up's of these patients in the growth and development period after the operation is critical.

Introduction: Myelomeningocele (MMC) is the most common cause of neurogenic bladder dysfunction in children. Neurogenic bladder dysfunction is developed before birth due to autonomous nervous system affected prenatally in patients with MMC. The aim of this study was to share urodynamic study findings before MMC repair and to discuss the correlation with neurological evaluation.

Background: The aim of this study was to present clinical and radiological results of myelomeningocele (MMC) patients treated with the sliding growing rod (SGR) technique after kyphectomy.

Methods: Between 2016 and 2019, 30 patients (21 males and nine females) who underwent the SGR technique with kyphectomy and posterior instrumentation due to MMC were retrospectively reviewed. Patients' pre- and postoperative kyphosis, scoliosis, correction rates, bleeding during surgery, blood supply during and after surgery, operation time, instrumentation levels, number of vertebrae removed, MMC onset levels, hospital stay, annual lengthening amounts, and complications were evaluated.

Introduction: Monocytosis Workflow Optimization rule set has been developed by using mono-dysplasia-score to determine reactive monocytosis and prevent unnecessary blood smear of these patients and for detection of chronic myelomonocytic leukemia cases during complete blood count. In our study, we aimed to examine the contribution of Monocytosis Workflow Optimization rule set.

Methods: Adult patients with monocyte count ≥1.

Objectives: To assess phosphate and osmolarity levels of chronically administered eye drops commercially available in Turkey.

Materials And Methods: A total of 53 topical eye drops including 18 antiglaucoma drugs, 4 nonsteroidal anti-inflammatory drugs (NSAIDs), 10 corticosteroids, 7 antihistaminics, and 14 artificial tears identified using the Vademecum Modern Medications Guideline (2018) were included in the study. Phosphate levels were assessed using Roche Cobas C501 analyzer (Roche Diagnostics GmbH, Mannheim, Germany) and the respective kits.

Objective: The aim of this study was to compare the effects of conivaptan, an arginine vasopressin antagonist, and mannitol, a sugar alcohol, on cerebral ischemia-induced brain injury and edema in rats.

Materials And Methods: Fifty-eight 8-week-old male Sprague Dawley rats were randomly divided into five groups: control, ischemia-reperfusion (I/R)+saline, I/R+mannitol, I/R+10 mg/ml conivaptan, and I/R+20 mg/ml conivaptan. Cerebral ischemia was induced by common carotid artery occlusion for 30 minutes.

Context: Spina bifida, hydrocephalus, and similar congenital central nervous system (CNS) anomalies take origin from embryologic stages weeks before birth, but assessment and follow-up of these patients are important to figure and predict the effects of these anomalies on child's neurodevelopment.

Aims: To evaluate of multiple groups of congenital CNS anomalies in the neurodevelopment level.

Settings And Design: The study was conducted at a research and treatment center for spina bifida patients.

Background And Aim: Instrumentation is commonly used in spinal surgery to stabilize the fracture. In the present study, we aimed to compare the early and late changes seen in bone production and degradation products in patients with traumatic spinal fracture who had been treated surgically or conservatively.

Materials And Methods: Forty-three patients were admitted to the Neurosurgery Department with thoracolumbar or lumbar fracture in this prospective study.

Objective: Our aim of this study was to determine effective doses of progesterone which has a vasodilatory effect during the early stage of vasospasm. Cerebral vasospasm (CV) is a predominant cause of morbidity and mortality which develops following subarachnoidal hemorrhage (SAH). Etiopathogenesis of CV is multifactorial.

Introduction: Scoliosis, kyphosis, and sacral agenesis (SA) are common spine deformities in myelomeningocele (MMC) patients. Surgery of spine deformities in MMC patients is associated with various difficulties as infection, pathological skin breakage, instrumentation failure, and neurological deterioration. The purposes of this study are to share our clinical experience and discuss different surgical techniques which are defined in the literature.

Russell-Silver syndrome is a rare heterogeneous disorder mainly characterized by intrauterine and postnatal growth retardation, craniofacial disproportion, clinodactyly, variation in urogenital development, and skeletal asymmetry. It is rare to come across tethered cord-associated Russell-Silver syndrome. We report a rare case of Russell-Silver syndrome associated with low conus medullaris in a 2-year-old patient with demonstrative phenotype.
