“Bronchopulmonary dysplasia (BPD) refers to a heterogeneous group of lung disorders in infants that is commonly associated with prematurity and surfactant deficiency. BPD results from the complex interplay between impairments in the premature lung such as surfactant deficiency, perinatal insults such as infection, and damage resulting from supportive care of the infant due to barotrauma or volutrauma from mechanical
ventilation and oxygen toxicity from supplemental oxygen administration. These factors result in chronic Selleck MK-0518 inflammation in the infant lung with recurring cycles of lung damage and repair that may impair alveolarization and vascularization in the developing lungs. As our insight in how to treat BPD improves along with the ability to do so with developing technology and therapies, the underlying pathogenesis will also change. The term ‘new’ BPD is now commonly learn more used, to describe the changes seen in the post-surfactant era. This discussion reviews the pathogenesis of BPD according to the current medical literature. Copyright (C) 2009 S. Karger AG, Basel”
“Hereditary hemorrhagic telangiectasia (HHT) is a rare but life-threatening disease characterized by multi system telangiectasias and arteriovenous malformations (AVM). Complications in adults have been reported extensively, but neonatal (NN) complications have
only been published in incidental case reports. In this paper, we present a literature review on NN pulmonary AVM related to HHT, following our own experience with a NN death due to this disease. As prenatal diagnosis of pulmonary AVM is feasible, we recommend that a family history of HHT should be an indication for expertise ACY-738 research buy prenatal anomaly scanning, in order to organise optimal NN support at birth.”
“Introduction: Nephrolithiasis in the United States has been on the rise
during the past several decades. Temperature has been shown to directly correlate with increased stone disease. We examine the association between climactic factors and monthly urolithiasis presentation rates for 6 years at a single institution in New York City.
Methods: Emergency department (ED) data on patient visitations were collected along with patient demographics. Meteorological data were collected using the website “”Weather Underground”" (www.wunderground.com). Average monthly temperature, dew point, precipitation, and sea level pressure were obtained and relative humidity was calculated using the dew point. Monthly urolithiasis visitations and the correlation of atmospheric factors were analyzed using an autoregressive integrated moving average (ARIMA) model.
Results: The total number of renal colic visits to the hospital’s ED from January 2007 through December 2012 tallied 3647 visits. The lowest average monthly rate per 1000 ED visits occurred in the month of February (28.8) and the highest in the month of August (43.8).
