The cellular mechanisms underlying the microvascular dysangiogenesis of bronchopulmonary dysplasia (chronic lung disease of the newborn) remain largely undetermined. We report unusual pulmonary vascular findings in a 27-week-gestation male newborn who died on the second day of life from intractable respiratory failure, following a pregnancy complicated by prolonged membrane rupture and persistent severe oligohydramnios. As expected, postmortem examination revealed pulmonary hypoplasia (lung/body weight ratio: 2...

A 65-year-old man with diabetes and a history of fever of unknown origin 2 weeks earlier complained of sudden decreased vision in the left eye. The patient was diagnosed with bilateral West Nile virus (WNV) chorioretinitis associated with occlusive retinal vasculitis in the left eye. Swept-source optical coherence tomography angiography (SS-OCTA) of the left eye showed extensive, well-delineated, hypointense non-perfusion areas and perifoveal capillary arcade disruption in the superficial capillary plexus, as well as larger non-perfusion areas, capillary rarefaction, and diffuse capillary network attenuation and disorganization in the deep capillary plexus...

The gut with its variety of microbiota may serve as an etiological origin of diseases. Gut microbes may also play a role in the pathogenesis of diseases beyond their simple nutritional maintenance and support. For example, gut protein aggregation, possibly aided by microbes as well as nasal influences, might be linked to disease that may move to the brain through the vagus nerve. To this end, Braak has offered a "dual-hit" hypothesis that proposes a novel etiology for Parkinson's disease (PD). The hypothesis places the initial origin of the disease in the nose and the gastrointestinal tract (GI) after infection by an unknown pathogen that could aggregate in the gut and then eventually spread to the brain via the autonomic plexuses...

Aggresomes are transient microtubule-dependent inclusion bodies that sequester misfolded proteins and are ultimately removed by autophagy. Here we report the generation of a choroid plexus carcinoma cell line; Children's Cancer Hospital Egypt (CCHE)-45, which is characterized by the constitutive formation of aggresomes. When examining the autophagy pathway as the main route for aggresomes clearance, CCHE-45 cells displayed increased autophagy flux mediated by MAP1LC3B. MAP1LC3A-Variant1 gene expression was silenced by promoter methylation...

We report the first trimester three-dimensional ultrasonographic findings in a 13-week-old fetus with complex phenotype and a de novo 4.7 Mb multigene deletion encompassing chromosome region 20q13.13-q13.2 detected by chromosomal microarray. Fetal sonography detected radial-ray anomalies in the form of bilateral absence of thumbs and the left club hand deformity. The presence of single atrioventricular canal instead of the atrial septal defect typical for Holt-Oram syndrome pointed us to rather suspect the SALL4 related diseases...

Background This paper investigates and discusses the effect of perioperative plexus catheter treatment in former CRPS patients. Patients and Methods A retrospective matched-pair analysis was conducted on 10 CRPS patients with comparable injuries, who underwent surgery in the disease-free interval. In 10 cases, the procedure was performed with perioperative plexus catheter treatment (intervention group), whereas 10 patients did not receive perioperative plexus catheter treatment (control group). Results In the intervention group, after a follow-up time of 105 (20-184) days after the last surgical procedure, pain intensity on the visual analogue scale (VAS; 0 to 10) was 6...

BACKGROUND AND OBJECTIVES: Psoas blocks are an alternative to femoral nerve blocks and have the potential advantage of blocking the entire lumbar plexus. However, the psoas muscle is located deeply, making psoas blocks more difficult than femoral blocks. In contrast, while femoral blocks are generally easy to perform, the inguinal region is prone to infection. We thus tested the hypothesis that psoas blocks are associated with more insertion-related complications than femoral blocks but have fewer catheter-related infections...

Herein we report the case of a 6-year-old girl with autism spectrum disorder (ASD) and weakness in the distal portion of the right upper limb. Although difficult to perform, nerve conduction studies indicated demyelinating neuropathy. Magnetic resonance imaging (MRI) showed swelling a nd high-intensity signals in the right brachial plexus and cervical spinal roots. The symptoms recovered after a single course of i.v. immunoglobulin. Electrophysiological indices and MRI findings also improved after treatment...

BACKGROUND: Ventriculoperitoneal shunt (VPS) placement has been implicated in extraneural metastasis of many primary central nervous system tumors. Reported cases include, but are not limited to, medulloblastoma, germ cell tumor, astrocytoma, oligodendroglioma, lymphoma, ependymoma, melanoma, and choroid plexus tumors. However, a literature review reveals no reported cases of extraneural metastasis of solitary fibrous tumor/hemangiopericytoma (SFT/HPC). CASE DESCRIPTION: Here we report the case of a 34-year-old man with recurrent intracranial malignant SFT/HPC who had undergone surgical tumor resection and subsequent placement of a VPS for obstructive hydrocephalus in 2004...

The proton-coupled folate transporter (PCFT-SLC46A1) is required for intestinal folate absorption and folate transport across the choroid plexus. This report addresses the structure/function of the 8th transmembrane helix. Based upon biotinylation of cysteine-substituted residues by MTSEA-biotin, 14 contiguous exofacial residues to Leu316 were accessible to the extracellular compartment of the 23 residues in this helix (Leu303-Leu325). Pemetrexed blocked biotinylation of six Cys-substituted residues deep within the helix implicating an important role for this region in folate binding...

Neural stem cells (NSCs) persist throughout life in the dentate gyrus and the ventricular-subventricular zone (V-SVZ), where they continuously provide new neurons and some glia. These cells are found in specialized niches that regulate quiescence, activation, differentiation, and cell fate choice. A key aspect of the regulatory niche is the vascular plexus, which modulates NSC behavior during tissue homeostasis and regeneration. During aging, NSCs become depleted and dysfunctional, resulting in reduced neurogenesis and poor brain repair...

PURPOSE: Hirschsprung's disease (HSCR) is a congenital disorder of the enteric nervous system characterized by the absence of ganglion cells in the Auerbach's and Meissner's plexuses. Although about 7% of cases are hereditary, the causal mutations have not been completely characterized. We encountered a novel family with inherited HSCR and screened them for causal mutations. METHODS: A Japanese family of five female patients and six unaffected individuals was subjected to a whole-exome analysis with a next-generation sequencer...

Choroid plexus cysts are rare lesions in the brain and are reported in humans and dogs. Herein, we report a choroid plexus cyst found in a 10-week-old female Sprague-Dawley rat. Histologically, a cyst measuring approximately 600 μm in diameter was found in the fourth ventricle of the brain. The cyst was lined with a single layer of flattened cells and was present in the connective tissue of the choroid plexus. Next to the cyst, a dilated tube was found with a similar morphology to the epithelium of the choroid plexus...

Delivering an adequate and homogenous dose to a large volume of recurrent cutaneous disease can be challenging even with modern techniques. Here, the authors describe a 3-isocenter hybrid electron and rapid arc photon radiation treatment plan to provide optimal tumor coverage to an extensive recurrence of inflammatory breast carcinoma. This approach allowed for homogeneous treatment of a large volume while effectively modulating dose to previously irradiated tissue and minimizing dose to the underlying heart, lungs and brachial plexus...
