Valproic acid effect on neural tube defects is not prevented by concomitant folic acid supplementation: Early chick embryo model pilot study.

Background: Neural tube defect is one of the most prevalent congenital malformations and it involves a variety of malformations ranging from anencephaly to spina bifida. Folic acid supplementation during pregnancy is known to reduce risk of neural tube defects. Antiepileptic drugs have been associated with neural tube defects, one of which is valproic acid.

Cranially migrated lumbar intervertebral disc herniations: A multicenter analysis with long-term outcome.

Objective: Risk factors of cranial migration were investigated in patients with lumbar disc herniation (LDH) that migrated in the cranial direction and the long-term outcomes are discussed in this study.

Materials And Methods: Patients who underwent surgery for LDH at four different centers between 2012 and 2017 were studied. Extraligamentous discs were located in the lateral part of the posterior longitudinal ligament (PLL) within the spinal canal of the axial plane, and subligamentous discs were located under the PLL.

A Data Adaptive Biological Sequence Representation for Supervised Learning.

Proper expression of the genes plays a vital role in the function of an organism. Recent advancements in DNA microarray technology allow for monitoring the expression level of thousands of genes. One of the important tasks in this context is to understand the underlying mechanisms of gene regulation.

Laparoscopy in the management of lumboperitoneal shunt catheter in obese patients with pseudotumor cerebri.

Lumboperitoneal shunts are widely used for the treatment of patients diagnosed with pseudotumor cerebri (PTC). Obesity is a risk factor for PTC. In particular, catheter migration out of the abdominal cavity is more commonly observed in morbidly obese patients.

Evaluation of Cortical Brain Parenchyma by Diffusion and Perfusion MRI Before and After Chronic Subdural Hematoma Surgery.

Aim: To evaluate microcirculatory changes in neighboring parenchyma as a result of pressure due to chronic subdural hematoma (CSDH) in early and late periods after hematoma drainage.

Material And Methods: The subject group consisted of 25 patients who underwent CSDH drainage. Brain diffusion and perfusion magnetic resonance images (MRIs) were obtained preoperatively, and at 48 hours (early period) and 2 months (late period) postoperatively.

Smartphones and Programmable Shunts: Are These Indispensable Phones Safe and Smart?

The effect of hypericum perforatum on kidney ischemia/reperfusion damage.

It has been revealed in recent studies that Hypericum Perforatum (HP) is influential on cancer, inflammatory diseases, bacterial and viral diseases, and has neuroprotective and antioxidant properties. In this study, we investigated the effect of HP, which is known to have antioxidant and anti-inflammatory effects, on kidney I/R damage. Male Sprague-Dawley rats were divided into three groups, and each of the groups had eight rats: The Control Group; the Ischemia/Reperfusion (I/R) Group; and the IR + HP Group which was treated with 50 mg/kg of HP.

Migration of fragments into the spinal canal after intervertebral polyethylene glycol implantation: an extremely rare adverse effect: Case report.

Percutaneous intervertebral hydrogel (polyethylene glycol) implantation is a current treatment procedure that aims to restore hydration of a degenerated disc. There have been a few studies that claim that polyethylene glycol is successful for pain relief as the intervertebral space restores its hydration and elasticity. This procedure is reported to be indicated for discogenic low-back pain and mild radicular pain as it contributes to disc restoration.

Spontaneous Rupture of Intracranial Dermoid Cyst Mimicking a Primary Psychiatric Disorder.

We discussed the case of a 14-year-old patient with acute onset of psychiatric symptoms for two months who had been examined and different antipsychotic drugs had been prescribed by several psychiatrists without any neuroradiological imaging. Because of unresponsiveness to the antipsychotic drugs, computed tomography and magnetic resonance imaging were performed which revealed a ruptured intracranial dermoid cyst. The patient underwent surgery and antipsychotic medications were withdrawn in short time.

Free floating ventricular shunt catheter between lateral ventricles: a case report of an unusual ventriculoperitoneal shunt complication.

Ventriculoperitoneal (VP) shunt proximal tip disconnection is rarely seen as a shunt complication. Shunt dysfunction and hydrocephaly can develop due to this disconnection. Presented here is a case of a disconnection of the ventricular catheter from the shunt valve, which passed between both lateral ventricles by free floating in the brain CT.

How innocent is corpus callosum dysgenesis?

Background/aims: We aimed to investigate the relationship between corpus callosum dysgenesis (CCD) and associated asymptomatic closed spinal dysraphisms (CSDs).

Methods: 2,840 pediatric patients who were referred to our outpatient clinic between the years 2005 and 2013 with the diagnosis of microcephaly, macrocephaly, congenital hydrocephaly, epilepsy, mental-motor retardation and suspicion of intracranial mass were evaluated. Eighty-five patients were identified with a CCD by cranial magnetic resonance imaging (MRI).

Is the elapsed time following the placement of a ventriculoperitoneal shunt catheter an individual risk factor for shunt fractures?

In this study, we examined whether the resistance of peritoneal catheters against the retraction force changed over time following shunt placement, and the role of this resistance in shunt fracture is discussed. We investigated peritoneal catheters removed from patients treated with a ventriculoperitoneal shunt because of hydrocephalus; previously, patients underwent shunt revision. The maximum tension, maximum elongation and elongation percentages of the peritoneal catheters were measured.

Sacrococcygeal sinus angle: as a new anatomic landmark for the posterior approach of presacral lesions.

Purpose: We have discussed the importance of sacrococcygeal sinus angle (SSA), which is a new anatomical landmark in the surgery of presacral lesions. Because of its anatomical structure, the sacrum limits the surgical exposure like a compact barrier for the posterior surgical approach. The main aim of this paper is to explain the anatomical description and clinical importance of SSA in the surgery of presacral lesions.
