To describe the incidence, prenatal diagnosis, and perinatal outcome in fetuses with congenital dacryocystocele. All cases of congenital dacryocystocele diagnosed by prenatal ultrasound were identified using an established perinatal database. Prenatal ultrasound images were reviewed and perinatal outcome was abstracted from the medical records. The correlation between the cyst size, ...

A long-held dogma in neurosurgery is that parenchymal arteriovenous malformations (AVMs) are congenital. However, there is no strong evidence supporting this theory. An increasing number of documented cases of de novo formation of parenchymal AVMs cast doubt on their congenital nature and suggest that indeed the majority of these lesions ...

Amoebas and other freely moving protists differentiate into walled cysts when exposed to stress. As cysts, amoeba pathogens are resistant to biocides, preventing treatment and eradication. Lack of gene modification procedures has left the mechanisms of encystation largely unexplored. Genetically tractable Dictyostelium discoideum amoebas require cellulose synthase for formation of ...

Acanthamoeba cysts are resistant to unfavorable physiological conditions and various disinfectants. Acanthamoeba cysts have 2 walls containing various sugar moieties, and in particular, one third of the inner wall is composed of cellulose. In this study, it has been shown that down-regulation of cellulose synthase by small interfering RNA (siRNA) ...

Coarctation of the descending aorta is associated with significant cardiac lesions in up to 50% of the patients. Under such circumstances, surgical management requires consideration of the nature of the associated lesion which usually requires a median sternotomy for surgical correction. Coarctation of the aorta (COA) is, therefore, rarely associated ...

BACKGROUND: Hyaluronan is an extracellular matrix glycosaminoglycan involved in invasion, proliferation and metastasis of various types of carcinomas. In many cancers, aberrant hyaluronan expression implicates disease progression and metastatic potential. Melanoma is an aggressive skin cancer. The role of hyaluronan in melanoma progression including benign nevi and lymph node metastases ...

: Sulfur mustard (SM) exposure results in dose-dependent morbidities caused by cytotoxicity and vesication. Although lesions resulting from ocular exposure often resolve clinically, an idiopathic delayed mustard gas keratopathy (MGK) can develop after a moderate or severe exposure. Sequelae include persistent keratitis, recurring epithelial lesions, corneal neovascularization, and corneal degeneration, ...

Central nervous system (CNS) relapse is an uncommon devastating complication of diffuse large B-cell lymphoma (DLBCL) that usually occurs within 2years from initial diagnosis. Its pathophysiology is poorly understood and there is no consensus on the definition of high-risk patients for CNS relapse. Consequently, an empirical and highly variable practice ...

According to a longstanding view, inferior as opposed to superior parietal cortex critically contributes to the spatial attentional deficits encountered following unilateral parietal ischemic lesions. We review the evidence on which this view is based and contrast it with more recent structural lesion evidence concerning the critical role of the ...

It is difficult to completely remineralize carious lesions because diffusion into the interior of the lesion is inhibited as new mineral is deposited in the outermost layers. In previous remineralization studies employing polarization sensitive optical coherence tomography (PS-OCT), two models of remineralization were employed and in both models there was ...

PURPOSE OF REVIEW: To clearly define single-organ vasculitis (SOV) and distinguish diffuse from focal SOV. To delineate clinical, laboratory, and histopathological features useful in differentiating focal SOV from systemic vasculitis affecting the same territory. RECENT FINDINGS: SOV may affect organs in a diffuse or multifocal fashion (e.g. central nervous system ...

Dystroglycan is a laminin receptor, which with dystrophins and other components forms the dystrophin-dystroglycan complex. It has an important role in the formation of gliovascular connections, cerebral vascularisation and blood-brain barrier. Dystroglycan consists of two sub-units, α and β. Previous studies demonstrated that the β-dystroglycan immunoreactivity of cerebral vessels temporarily ...

Toxoplasma gondii is an intra-cellular parasite that infects humans through vertical and horizontal transmission. The cysts remain dormant in the brain of infected humans and can reactivate in immunocompromised hosts resulting in acute toxoplasmic encephalitis which may be fatal. We determined the onset and progression of brain cysts generation in ...

Hemifacial microsomia (OMIM164210) is a condition featuring unilateral ear anomalies and ocular epibulbar dermoids associated with unilateral underdevelopment of the craniofacial bony structures. Other associated anomalies have also been described, especially spinal malformations, and the term oculoauriculovertebral dysplasia spectrum (OVAS) was suggested to include the three predominant systems involved. Both ...

Pancreatic ductal adenocarcinoma (PDAC) and its precursor lesions, pancreatic intraepithelial neoplasia, (PanIN), display a ductal phenotype. However, there is evidence in genetically defined mouse models for PDAC harbouring a mutated kras under the control of a pancreas-specific promoter that ductal cancer might arise in the centroacinar-acinar region, possibly through a ...

This case report describes a technique used to treat smooth surface white spot lesions microinvasively. It is based on the infiltration of an initial enamel caries lesion with low-viscosity light-curing resins called infiltrants. The surface layer is eroded and desiccated, followed by resin infiltrant application. The resin penetrates into the ...
