Giant encephalocele in newborns: prenatal diagnosis, management and outcome.
Childs Nerv Syst
January 2025
Department of Global Health, Faculty of Health Sciences, McMaster University, 1280 Main St W, Hamilton, ON, L8S 4L8, Canada.
Background: A giant encephalocele associated with Chiari malformation is a rare congenital anomaly from a cephalad neural tube defect. Early prenatal diagnosis and parental counseling are essential; as early surgical intervention can improve outcomes.
Methods: Between 2010 and 2023, twenty-seven newborns out of 43,815 delivered at our institution were diagnosed with encephaloceles, including seven cases of giant encephalocele associated with Chiari malformation type III.
Tunneled Pleural Catheters: An Effective Nonsurgical Alternative for Nonexpandable Lung in Chronic Pleural Infection.

Division of Thoracic Surgery and Interventional Pulmonology, Beth Israel Deaconess Medical Center, Harvard Medical School.
Background: Open window thoracostomy (OTW) is the standard of care for debilitated patients with chronic pleural infection and nonexpandable lungs (NEL) who are not candidates for major surgical intervention. Tunneled pleural catheters (TPC) offer tremendous treatment potential in this setting based on their efficacy in malignant pleural effusion and NEL. We aim to assess the efficacy, safety, and health care utilization of TPC in this setting.

A linear spot-type multipass cell-enhanced fiber-optic photoacoustic gas microprobe is proposed. To further reduce the volume of the gas chamber and enhance the photoacoustic signal, we designed the cross section of the photoacoustic tube as a slit with a height of 10 mm and a width of 1.5 mm.

The conformation of a series of zero-generation polyamidoamine dendrimers end-labeled with four 1-pyrene-butyroyl, -hexanoyl, -octanoyl, -decanoyl, and -dodecanoyl derivatives, referred to as the PyCX-PAMAM-G0 samples with = 4, 6, 8, 10, and 12, respectively, was characterized in ,-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), and aqueous solutions of 50 mM sodium dodecyl sulfate (SDS) or 50 mM dodecyltrimethylammonium bromide (DTAB). The conformation of the PyCX-PAMAM-G0 samples was determined from the global model-free analysis (MFA) of the fluorescence decays, which yielded the average rate constant (⟨⟩) for pyrene excimer formation (PEF) between an excited and a ground-state pyrenyl labels, with ⟨⟩ being proportional to the local concentration ([Py]) of the pyrenyl labels within the macromolecular volume; ⟨⟩-vs-[Py] plots yielded straight lines passing through the origin in DMF and DMSO, demonstrating that the internal segments of the dendrimers obeyed Gaussian statistics in these two solvents. In aqueous surfactant solutions, the hydrophobic pyrenyl labels induced the interactions of the PyCX-PAMAM-G0 dendrimers with the SDS and DTAB micelles.

Molecular dynamics (MD) simulations are essential for understanding molecular phenomena at the atomic level, with their accuracy largely dependent on both the employed force field and sampling. Polarizable force fields, which incorporate atomic polarization effects, represent a significant advancement in simulation technology. The polarizable Gaussian multipole (pGM) model has been noted for its accurate reproduction of ab initio electrostatic interactions.
