The treatment of brain arteriovenous malformations (AVMs) remains a significant challenge, especially hemorrhagic AVMs which are unsuitable for microsurgery or radiosurgery. We demonstrate an AVM located in the left basal ganglia area, supplied by slender arteries, and treated by the transvenous pressure cooker technique. Herein, we describe the procedure and outline the crucial points and indications for this technique.

INTRODUCTION: Postnatal growth restriction is considered a universal problem in extremely premature infants (EPI), and causes great concern due to the possible relationship between nutrition, sub-optimal postnatal growth, and neurodevelopment delay. OBJECTIVES: To describe the weight gain in EPI and to determine the changes in the length and head circumference (HC) at hospital discharge in survivors. PATIENTS AND METHODS: The study included 4,520 Caucasian EPI from single pregnancies and without severe malformations, born in the centres participating in the Spanish SEN1500 network (2002-2011)...

This study aimed to assess the effects of Basagran(®) on zebrafish (Danio rerio) embryos. The embryos were exposed to Basagran(®) at concentrations ranging from 120.0 to 480.6 mg/L, and the effects on embryo development (up to 96 h) and bacterial communities of 96 h-larvae were assessed. The embryo development response was time-dependent and concentration-dependent (106.35 < EC50 < 421.58 mg/L). The sensitivity of embryo-related endpoints decreased as follows: blood clotting in the head and/or around the yolk sac > delay or anomaly in yolk sac absorption > change in swimming equilibrium > development of pericardial and/or yolk sac oedema > scoliosis...

PURPOSE: The spectrum of male urethral duplication is heterogeneous and it includes the Y-duplication. The malformation is rare and there is only a few case series reported in the literature. The management of Y-forms remains challenging for the surgeon and the long-term follow-up is still scarcely investigated. We report our 40-year experience in the management of patients with Y-duplication. MATERIALS AND METHODS: We conducted a restrospective analysis collecting information of patients with urethral Y-duplication treated at our department from April 1975 to April 2015...

BACKGROUND: Renal vein anomalies are relatively infrequent and generally asymptomatic. Preoperative knowledge of such variants is, however, of paramount importance in several angiographic and surgical procedures including renal venography, renal vein sampling, spermatic embolization, and renal transplantation. Inadequate knowledge and failure to recognize such anatomic variations may lead to several operative hazards including hemorrhage, nephrectomy, and even death. CASE PRESENTATION: We report a case of bilateral anomalous drainage of the posterior divisions of renal veins into the azygos venous system in a 20-year-old woman of African descent from Tanzania who presented to us with a 12-year history of recurrent anemia...

BACKGROUND: There has been a recent increase in the number of newborns with brain malformations due to congenital infections, but the impact of these diseases remains largely under ascertained in middle-income and low-income countries. This case report presents a fetal anencephaly following maternal toxoplasma and rubella co-infection in a resource-limited setting and the challenges faced by the patient and the health care provider in the management of the condition. CASE PRESENTATION: A 25-year-old black Cameroonian woman of Bakossi origin, gravida3 para1010, presented with a positive rubella and toxoplasma immunoglobulin G serologic test at 21 weeks of pregnancy; she could not benefit from a fetal morphologic ultrasound partly because there was none at the site of her antenatal clinic and because there were accessibility constraints getting to the nearest referral hospital approximately 100 km away...

This review accompanies a 2016 SFN mini-symposium presenting examples of current studies that address a central question: How do neural stem cells (NSCs) divide in different ways to produce heterogeneous daughter types at the right time and in proper numbers to build a cerebral cortex with the appropriate size and structure? We will focus on four aspects of corticogenesis: cytokinesis events that follow apical mitoses of NSCs; coordinating abscission with delamination from the apical membrane; timing of neurogenesis and its indirect regulation through emergence of intermediate progenitors; and capacity of single NSCs to generate the correct number and laminar fate of cortical neurons...

Resting-state functional connectivity MRI (rs-fcMRI) is a technique that identifies connectivity between different brain regions based on correlations over time in the blood-oxygenation level dependent signal. rs-fcMRI has been applied extensively to identify abnormalities in brain connectivity in different neurologic and psychiatric diseases. However, the relationship among rs-fcMRI connectivity abnormalities, brain electrophysiology and disease state is unknown, in part because the causal significance of alterations in functional connectivity in disease pathophysiology has not been established...

OBJECTIVE Brain arteriovenous malformations (AVMs) are the most common cause of spontaneous intracranial hemorrhage in pediatric patients (age < 18 years). Since the cumulative lifetime risk of AVM hemorrhage is considerable in children, an improved understanding of the risk factors influencing hemorrhagic presentation may aid in the management of pediatric AVMs. The aims of this first of a 2-part multicenter, retrospective cohort study are to evaluate the incidence and determine the predictors of hemorrhagic presentation in pediatric AVM patients...

OBJECTIVE Pediatric patients are at risk for the recurrence of brain arteriovenous malformation (AVM) after resection. While there is general consensus on the importance of follow-up after surgical removal of an AVM, there is a lack of consistency in the duration of that follow-up. The object of this systematic review was to examine the role of follow-up imaging in detecting AVM recurrence early and preventing AVM rupture. METHODS This systematic review was performed using articles obtained through a search of the literature contained in the MeSH database, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Lateral meningocele syndrome (LMS) is a rare genetic connective tissue disorder. It is associated with morphological changes similar to those of other connective tissue disorders, with the unique distinction of multiple, often bilateral and large, lateral meningoceles herniating through the spinal foramina. In some cases, these lateral meningoceles can cause pain and discomfort due to their presence within retroperitoneal tissues or cause direct compression of the spinal nerve root exiting the foramen; in some cases compression may also involve motor weakness...

The authors report on an 81-year-old woman with a pathologic hangman's fracture secondary to a complex arteriovenous fistula (AVF). The patient presented with severe, unremitting neck pain and was found to have fractures bilaterally through the pars interarticularis of C-2 with significant anterior subluxation of C-2 over C-3 along with widening of the left transverse foramen. Due to an abnormally appearing left vertebral artery (VA) on CT angiography, the patient underwent conventional angiography, which revealed a complex AVF stemming from the left VA at the level of C-2 with dilated posterior cervical veins and a large venous varix...

BACKGROUND: Chloroplast plays a vital role in plant development and growth. The pentatricopeptide repeat (PPR) gene family is one of the largest gene families in plants. In addition, cold stress affects a broad spectrum of cellular components, e.g. chloroplast, and metabolism in plants. However, the regulatory mechanism for rice PPR genes on chloroplast development still remains elusive under cold stress. RESULT: In this paper, we characterized a new rice PPR gene mutant tcd10 (thermo-sensitive chlorophyll-deficient mutant 10) that exhibits the albino phenotype, malformed chloroplast and could not survive after the 5-leaf stage when grown at 20 °C, but does the normal phenotype at 32 °C...

Terminal chromosome 1q deletion is rarely reported but causes typical malformations that have been well described in childhood. Clinical features include facial dysmorphy, growth and/or psychomotor retardation, brain agenesis or hypoplasia of the corpus callosum, epilepsy and occasional urogenital or cardiac malformations. The diagnosis of this condition is usually made at birth. The rare cases of antenatal diagnosis were based on microcephaly and growth retardation. In the present case, the foetus presented with an hypoplasia of the corpus callosum, a dysmorphic profile and a single umbilical artery...

Complete atrioventricular (AV) block is a rare affection in children. It is the consequence of abnormal conduction tissue within a cardiac malformation or it is due to cardiac injury. Yet the etiology of late complete atrioventricular block in child remains mostly unknown. The treatment of children's Complete atrioventricular block is the implantation of a pacemaker with immediate results satisfactory in the absence of associated cardiomyopathy. In this observation we will treat three cases.

Maternal diabetes is one of major causes of congenital malformations in offspring, but the underlying mechanism is still unclear. MiRNAs play an important role in transcriptional and post-transcriptional regulation of gene expression. However, no miRNA expression profiling of hyperglycemic offspring are thus far available. Female mice were made diabetic with streptozotocin, treated with slow-release insulin tablets, and mated. MiRNA expression profiling with Next Generation Sequencing on the SOLiD5 platform was performed on 8 control and 5 hyperglycemic embryonic day (ED)8...

BACKGROUND: In non-walking children with severe spasticity, daily care can be difficult and many patients suffer from pain. Selective dorsal rhizotomy (SDR) reduces spasticity in the legs, and therefore has the potential to improve daily care and comfort. AIM: To examine effects of SDR on daily care and comfort in non-walking children with severe spasticity due to different underlying neurological conditions. METHODS: Medical history, changes in daily care and comfort and satisfaction with outcome were assessed retrospectively in non-walking children who underwent SDR in our center, with a mean follow-up of 1y 7m (range 11m-4y 3m)...
