Aqueductal developmental venous anomaly as an unusual cause of congenital hydrocephalus: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Aqueductal stenosis may be caused by a number of etiologies including congenital stenosis, tumor, inflammation, and, very rarely, vascular malformation. However, aqueductal stenosis caused by a developmental venous anomaly presenting as congenital hydrocephalus is even more rare, and, to the best of our knowledge, has not yet been reported in the literature. In this study, we review the literature and report the first case of congenital hydrocephalus associated with aqueductal stenosis from a developmental venous anomaly.</p> <p>Case presentation</p> <p>The patient is a three-day-old, African-American baby girl with a prenatal diagnosis of hydrocephalus. She presented with a full fontanelle, splayed sutures, and macrocephaly. Postnatal magnetic resonance imaging showed triventricular hydrocephalus, suggesting aqueductal stenosis. Examination of the T1-weighted sagittal magnetic resonance imaging enhanced with gadolinium revealed a developmental venous anomaly passing through the orifice of the aqueduct. We treated the patient with a ventriculoperitoneal shunt.</p> <p>Conclusions</p> <p>Ten cases of aqueductal stenosis due to venous lesions have been reported and, although these venous angiomas and developmental venous anomalies are usually considered congenital lesions, all 10 cases became symptomatic as older children and adults. Our case is the first in which aqueductal stenosis caused by a developmental venous anomaly presents as congenital hydrocephalus. We hope adding to the literature will improve understanding of this very uncommon cause of hydrocephalus and, therefore, will aid in treatment.</p

Feelings of burden among family caregivers of people with spinal cord injury in Turkey

Study design: The study was designed as a cross-sectional survey. Objectives: The purpose of the study was to examine the level of feelings of burden in family caregivers of people with spinal cord injury (SCI) in Turkey, and to explore its predictors. Setting: Turkey. Methods: One hundred family caregivers of people with SCI completed measures of burden of caregiving, depression, social support and physical health. The SCI participants completed a measure of functional independence. Multivariate statistics and structural equation modeling (SEM) were conducted to identify significant predictors of caregiver burden. Results: Caregiver burden was significantly related to caregivers’ feelings of depression. SEM analysis showed that social support from family and from friends predicted caregiver burden via depression. Caregivers’ age, sex, educational level, physical health and household income did not significantly predict their feelings of depression or burden. Conclusions: Our findings revealed that support received from both families and friends is an important source for alleviating the depressive feelings of caregivers and, in return, their burden in the caregiving. In Turkey, high support from family members is expected and is important for psychological well-being, yet the current study showed that the support received from friends also has unique contribution to the well-being of the caregivers of persons with SCI. Overall, our findings highlight the importance of supportive relationships between family as well as friends for the caregivers who may have to provide lifetime care for their family member with special needs.WOS:000407265700012Scopus - Affiliation ID: 60105072PMID: 28169295Science Citation Index Expanded - Social Sciences Citation IndexQ2 - Q3ArticleUluslararası işbirliği ile yapılan - EVETAğustos2017YÖK - 2016-1

Proton Mr Spectroscopy: Higher Right Anterior Cingulate N-Acetylaspartate/Choline Ratio in Asperger Syndrome Compared with Healthy Controls

BACKGROUND AND PURPOSE: One former study reported higher prefrontal N-acetylaspartate (NAA) levels in patients with Asperger syndrome (AS). The objective of the current study was to test the hypothesis that patients with AS would have higher dorsolateral prefrontal and anterior cingulate cortex NAA/creatine (Cr) and that NAA/Cr would be correlated with symptom severity. MATERIALS AND METHODS: NAA/choline (Cho), NAA/Cr, and Cho/Cr values revealed by H-1-MR spectroscopy in 14 right-handed male patients with AS (6 medicated with risperidone), 17-38 years of age, diagnosed by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria were compared with those of 21 right-handed male controls frequency-matched by age and intelligence quotient scores. RESULTS: Patients with AS had significantly higher anterior cingulate NAA/Cho levels (z = -2.18, P .028); there was a statistical trend for higher anterior cingulate NAA/Cr (z = - 1.81, P =.069) that was significant when only the unmedicated patients with AS were taken into account (z = -1.95, P.050). There were no significant differences in dorsoleteral prefrontal MR spectroscopy values. CONCLUSIONS: Our findings show that individuals with AS had higher NAA/Cho levels in the right anterior cingulate compared with healthy controls and that higher anterior cingulate NAA/Cho levels were correlated with higher Yale-Brown Obsessive Compulsive Scale total scores.WoSScopu

Focused ultrasound in neuroscience. State of the art and future perspectives

Transcranial MR-guided Focused ultrasound (tcMRgFUS) is a surgical procedure that adopts focused ultrasounds beam towards a specific therapeutic target through the intact skull. The convergence of focused ultrasound beams onto the target produces tissue effects through released energy. Regarding neurosurgical applications, tcMRgFUS has been successfully adopted as a noninvasive procedure for ablative purposes such as thalamotomy, pallidotomy, and subthalamotomy for movement disorders. Several studies confirmed the effectiveness of tcMRgFUS in the treatment of several neurological conditions, ranging from motor disorders to psychiatric disorders. Moreover, using low-frequencies tcMRgFUS systems temporarily disrupts the blood–brain barrier, making this procedure suitable in neuro-oncology and neurodegenerative disease for controlled drug delivery. Nowadays, tcMRgFUS represents one of the most promising and fascinating technologies in neuroscience. Since it is an emerging technology, tcMRgFUS is still the subject of countless disparate studies, even if its effectiveness has been already proven in many experimental and therapeutic fields. Therefore, although many studies have been carried out, many others are still needed to increase the degree of knowledge of the innumerable potentials of tcMRgFUS and thus expand the future fields of application of this technology
