Factors associated with community acquired severe pneumonia among under five children in Dhaka, Bangladesh: A case control analysis.

Background: Pneumonia is the leading cause of death in children globally with the majority of these deaths observed in resource-limited settings. Globally, the annual incidence of clinical pneumonia in under-five children is approximately 152 million, mostly in the low- and middle-income countries. Of these, 8.

Parental satisfaction with being present in the operating room during the induction of anesthesia prior to pediatric neurosurgical intervention: a qualitative analysis.

OBJECTIVE Parental presence in the operating room during the induction of anesthesia (PPIA) has been shown to decrease parent and child anxiety and increase satisfaction with patient experience in outpatient otolaryngological procedures, such as tympanostomy tube placement. PPIA for other procedures, such as a major neurosurgical intervention, has been a practice at the authors' institutions for many years. This practice is not universally accepted across the United States, and the potential benefits for patients and families have not been formally evaluated.

Outpatient follow-up of nonoperative cerebral contusion and traumatic subarachnoid hemorrhage: does repeat head CT alter clinical decision-making?

Objectives: Many neurosurgeons obtain repeat head CT at the first clinic follow-up visit for nonoperative cerebral contusion and traumatic subarachnoid hemorrhage (tSAH). The authors undertook a single-center, retrospective study to determine whether outpatient CT altered clinical decision-making.

Methods: The authors evaluated 173 consecutive adult patients admitted to their institution from April 2006 to August 2012 with an admission diagnosis of cerebral contusion or tSAH and at least 1 clinic follow-up visit with CT.

Uptake of pyrene by NaCl, NaNO3, and MgCl2 aerosol particles.

Photoelectric charging experiments measure heterogeneous uptake coefficients for pyrene on model marine aerosol particles, including NaCl, NaNO(3), and MgCl(2). The analysis employs a multilayer kinetic model that contains adsorption and desorption rate constants for the bare aerosol surface and for pyrene-coated surfaces. First coating the aerosol particles with a pyrene layer and following the desorption using both t-DMA and photoelectric charging yields the desorption rate constants.
