MicroRNAs (miRNAs) play critical roles in regulating cancer cell proliferation, migration, survival and sensitivity to chemotherapy. The potential application of using miRNAs for cancer prognosis holds great promise but miRNAs with predictive value remain to be identified and underlying mechanisms of how they promote or suppress tumorigenesis are not completely understood. Here, we show a strong correlation between miR203 expression and brain cancer patient survival. Low miR203 expression is found in subsets of brain cancer patients, especially glioblastoma...

In 1976 an infant boy initially presented with a choroidal vein of Galen malformation (cVOGM). Craniotomy and clipping of the anterior cerebral artery and posterior choroidal arteries was performed, which was reported in the literature 40 years ago. The patient remained asymptomatic until age 42 when he re-presented with an isolated intraventricular hemorrhage. Angiography demonstrated cVOGM with venous sinus occlusive disease leading to venous hypertension and subsequent intraventricular hemorrhage. The angiogram also demonstrated a 'pseudo-nidus' composed of multiple arterial-to-arterial anastomoses that had developed as a result of the original surgical treatment...

INTRODUCTION: Pediatric low-grade tumors are found in roughly 1-3 % of patients with childhood epilepsy; seizures associated with these tumors are often medically refractory and often present a significant morbidity, greater than the presence of the tumor itself. DISCUSSION: The unique morbidity of the seizures often requires an epilepsy surgical approach over a standard oncologic resection to achieve a reduction in morbidity for the child. Multiple quality-of-life studies have shown that unless a patient is seizure-free, they remain disabled throughout their life; the best way to achieve this in our patient population is with a multidisciplinary team approach with treatment goals focusing primarily on the epilepsy...

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare lesion that typically manifests in the first year of life, most commonly involving the facial bones. We present 2 infants with MNTI involving the posterior skull with associated compression of the superior sagittal sinus (SSS). A review of the anatomical locations of MNTI is offered, and the implications of SSS involvement are described. This represents the first known description of MNTI with involvement of the posterior SSS.

Cryptogenic organizing pneumonia (COP), previously called bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathological disorder of unknown aetiology but increasingly reported. It usually presents with symptoms of dyspnea, cough, fever, weight loss accompanied by the presence of alveolar opacities on chest radiograph. Haemoptysis, described as blood streaking has only rarely been reported as primary presentation of COP. Herein, we report a case of COP in which submassive haemoptysis was the main clinical manifestation...

There is little mention in the literature about achalasia as an etiologic factor of Bronchiolitis obliterans organizing pneumonia (BOOP). In this study, a case of BOOP, which appeared to be secondary to achalasia is reported. A 35 years old man present with nonproductive cough, chills and fever from two month ago. Due to permanent consolidation in mid zone of right lung and unresponsive to antibiotics, transthoracic needle biopsy was done that showed BOOP. Due to esophageal dilatation in chest computerized tomography (CT) scan, endoscopy and esophagogram was done that showed achalasia...

The etiology of bronchiolitis obliterans organizing pneumonia (BOOP) remains controversial. While it has been reportedly associated with several connective tissue disorders, there are only rare reports of BOOP associated with systemic lupus erythematosus (SLE). Herein, we report a 56-year-old female patient who presented with dyspnea on exertion, cough, fever, and joint pain of her left wrist and fingers as initial symptoms. Laboratory tests revealed positivity for anti-nuclear antibody, anti-Ro, and anti-double strand DNA antibody...

For the first time this study reports on the presence of microplastics (1 nm to <5 mm) in the gastrointestinal tracts of small semipelagic fish (Boops boops) in the Balearic Islands (Mediterranean Sea) from March to May 2014. The results show microplastic ingestion in 68% of full stomach samples with an average of 3.75 items per fish. Only filament type microplastics were observed in B. boops full gastrointestinal tracts. The frequency of occurrence of microplastics was high, with values ranging from 42% to 80%, in comparison to the other ingested items...

PURPOSE: Imaging descriptions of posterior fossa ependymoma in children have focused on magnetic resonance imaging (MRI) signal and local anatomic relationships with imaging location only recently used to classify these neoplasms. We developed a quantitative method for analyzing the location of ependymoma in the posterior fossa, tested its effectiveness in distinguishing groups of tumors, and examined potential associations of distinct tumor groups with treatment and prognostic factors...

In the present study the role of the nocturnal migration of bogue Boops boops shoals to anthropogenically modified shallow littoral locations was examined, evaluating four alternative hypotheses: (1) feeding, (2) reproduction, (3) attraction of B. boops to artificial light and (4) concealment in the darkness related to predation avoidance. All hypotheses apart from predation avoidance were rejected, as B. boops tended to concentrate in shaded locations of wider illuminated areas, a finding not only important concerning fish behaviour, but also with significant management implications...

The childhood brain tumor, medulloblastoma, includes four subtypes with very different prognoses. Here, we show that paracrine signals driven by mutant β-catenin in WNT-medulloblastoma, an essentially curable form of the disease, induce an aberrant fenestrated vasculature that permits the accumulation of high levels of intra-tumoral chemotherapy and a robust therapeutic response. In contrast, SHH-medulloblastoma, a less curable disease subtype, contains an intact blood brain barrier, rendering this tumor impermeable and resistant to chemotherapy...

Low-grade neuroepithelial tumors (LGNTs) are diverse CNS tumors presenting in children and young adults, often with a history of epilepsy. While the genetic profiles of common LGNTs, such as the pilocytic astrocytoma and 'adult-type' diffuse gliomas, are largely established, those of uncommon LGNTs remain to be defined. In this study, we have used massively parallel sequencing and various targeted molecular genetic approaches to study alterations in 91 LGNTs, mostly from children but including young adult patients...

INTRODUCTION: Ipilimumab is a human monoclonal antibody that blocks cytotoxic-T-lymphocyte-associated antigen 4 (CTLA-4) and promotes antitumour immunity. It has recently been approved for the treatment of metastatic melanoma patients. Ipilimumab is now widely used and the spectrum of side effects because of autoimmunity is expanding. To our knowledge, this is the first report of an ipilimumab-induced pulmonary immune-related adverse event (irAE) that was successfully treated by macrolides without corticosteroids...

Organising pneumonia is a histopathological entity characterised by intra-alveolar buds of granulation tissue, intermixed myofibroblasts and connective tissue. Cryptogenic organising pneumonia (COP) is characterised by this particular histopathological pattern, along with typical clinical and imaging features, when no other underlying aetiology is found. COP (previously known as bronchiolitis obliterans organising pneumonia [BOOP]) is one of the rare variants of interstitial pneumonias. This condition is characterised by a rapid clinical and radiological improvement with steroid treatment...

OBJECTIVE Penetrating brain injury in civilians is much less common than blunt brain injury but is more severe overall. Gunshot wounds (GSWs) cause high morbidity and mortality related to penetrating brain injury; however, there are few reports on the management and outcome of intracranial GSWs in children. The goals of this study were to identify clinical and radiological factors predictive for death in children and to externally validate a recently proposed pediatric prognostic scale. METHODS The authors conducted a retrospective review of penetrating, isolated GSWs sustained in children whose ages ranged from birth to 18 years and who were treated at 2 major metropolitan Level 1 trauma centers from 1996 through 2013...
