[Clinical case: approach to the difficult airway in neonatology. Treacher-Collins syndrome].

If newborns have an airway obstruction, they require urgent and expert management to avoid mortality and morbidity. The definition of difficult airway includes problems in endotracheal intubation or positive pressure ventilation with bag and mask or T-piece resuscitator. Management should be based on an understanding of the pathophysiological mechanism responsible for difficult airway.

Corrosion Behavior of Steel-Reinforced Green Concrete Containing Recycled Coarse Aggregate Additions in Sulfate Media.

Novel green concrete (GC) admixtures containing 50% and 100% recycled coarse aggregate (RCA) were manufactured according to the ACI 211.1 standard. The GC samples were reinforced with AISI 1080 carbon steel and AISI 304 stainless steel.

pH-Triggered Release of NaNO Corrosion Inhibitors from Novel Colophony Microcapsules in Simulated Concrete Pore Solution.

Herein, pH-sensitive microcapsules containing NaNO corrosion inhibitors for protection of steel reinforced concrete were synthesized via water-in-oil-in-water (W/O/W) double emulsion using colophony as the wall material. The average microcapsule size was 79.07 μm in diameter and exhibited a high encapsulation efficiency of 83.

Corrosion Behavior of AISI 304 Stainless Steel Reinforcements in SCBA-SF Ternary Ecological Concrete Exposed to MgSO.

In this study, ternary ecological concrete (TEC) mixtures were produced with partial substitution of the ordinary Portland cement (OPC) by 10%, 20%, and 30% of sugar cane bagasse ash (SCBA) and silica fume (SF); a control mixture (100% OPC) was prepared according to ACI 211.1 standard. The studied TEC specimens were reinforced with AISI 304 stainless steel and AISI 1018 carbon steel rebars.

Seroprevalence of Bordetella pertussis among vaccinated and unvaccinated pregnant women and newborn infants in a university hospital of Buenos Aires.

Introduction: Pertussis is a highly contagious disease caused by Bordetella pertussis. It poses a high morbidity and mortality rate, especially among infants younger than 6 months old. In Argentina, pertussis incidence and mortality have increased over the past three decades.

Impact of an educational intervention to improve adherence to the recommendations on safe infant sleep.

Introduction: In developed countries, public campaigns promoting recommendations on safe infant sleep increased adherence to the supine sleeping position to more than 70% and, at the same time, reduced the incidence of sudden infant death syndrome by 53%.

Objetive: To determine the impact, at 60 days of life, of an educational intervention conducted in maternity centers aimed at improving adherence to the recommendations on safe infant sleep.

Material And Methods: Intervention study with historical control conducted between February 1st and September 30th of 2014 at the Maternity Center of Hospital Meisner and Hospital Universitario Austral.

[Pleuropulmonary blastoma, case report].

Pleuropulmonary blastoma is a rare lung tumor of childhood that can occur with cystic or solid lesions, as a radiological finding with or without respiratory symptoms. We report the case of a 2 year old toddler in his first pulmonary obstructive episode with suspected toracic malformation of the left upper lobe in his chest x-ray and tomography. Surgery was performed showing cystic malformation of the left upper lobe.

In Vitro Comparative Assessment of Mechanical Blood Damage Induced by Different Hemodialysis Treatments.

Gradual deterioration of red blood cells (RBCs) due to mechanical stress (chronic hemolysis) is unavoidable during treatments that involve extracorporeal blood circulation, such as hemodialysis (HD). This effect is generally undetectable and does not generate any acute symptoms, but it leads to an increase in plasma free hemoglobin (fHb). There are no absolute safety levels for fHb increase, indicating the need for an empirical evaluation using comparative testing.

Knowing what we do and doing what we should: quality assurance in hemodialysis.

An international group of around 50 nephrologists and scientists, including representatives from large dialysis provider organisations, formulated recommendations on how to develop and implement quality assurance measures to improve individual hemodialysis patient care, population health and cost effectiveness. Discussed were methods thought to be of highest priority, those clinical indicators which might be most related to meaningful patient outcomes, tools to control treatment delivery and the role of facilitating computerized expert systems. Emphasis was given to the use of new technologies such as measurement of online dialysance and ways of assessing fluid status.

Effectiveness of magnesium sulfate as initial treatment of acute severe asthma in children, conducted in a tertiary-level university hospital: a randomized, controlled trial.

Introduction: Magnesium sulfate is a calcium antagonist that inhibits bronchial smooth muscle contraction promoting bronchodilation. It is used for the management of acute severe asthma in children; however most of the studies have been performed in adults.

Objective: To evaluate the effectiveness of intravenous magnesium sulfate for the treatment of pediatric patients with acute severe asthma exacerbations.

Multidisciplinary evaluation for severity of hazards applied to hemodialysis devices: an original risk analysis method.

Background And Objectives: Risk analysis for medical devices is a crucial process to grant adequate levels of safety. Identification of device exposure-related hazards is one of the main objectives.

Design, Setting, Participants, & Measurements: Hazard analysis for hemodialysis devices has been performed by a multidisciplinary team involving engineers and clinical experts.

Monitor turnaround time and time efficiency in hemodialysis delivery--a global comparison.

Background/aims: Increasing cost pressure has forced shortening of dialysis treatments. The aim of this study was to benchmark the hemodialysis (HD) delivery monitor turnaround time and time efficiency in a global comparison.

Methods: 683 HD deliveries in 26 Gambro Healthcare clinics in Europe, Taiwan and the USA were assessed using the Treatment Mapping methodology.

Treatment mapping--a systematic methodology to assess quality, efficiency and variability in the hemodialysis delivery process.

Background/aims: Radical thinking about the design of industrial processes has greatly improved the quality and efficiency of manufacturing and services. Applying similar methods in healthcare to deliver quality care at lower costs would be valuable.

Methods: We have developed and validated a methodology--Treatment Mapping--to analyze the hemodialysis (HD) delivery as an operational process.

Clinical use of high-efficiency hemodialysis treatments: long-term assessment.

Significant technological changes in blood flow rate, dialyzer membrane permeability, bicarbonate dialysate, and ultrafiltration-controlled delivery systems permitted the implementation of 3 modifications to conventional hemodialysis as follows: high-efficiency hemodialysis (HEHD), high-flux hemodialysis (HFHD), and double-high-flux hemodiafiltration (HDF). The impact of these techniques on the quantity of the treatment administered and treatment time were assessed. One hundred and eighty-three patients were enrolled over 6 years.

Discrepancies between adequacy goals in peritoneal dialysis: role of gender.

Background: The National Kidney Foundation-Dialysis Outcome Quality Initiative (NKF-DOQI) recommends a weekly creatinine clearance (CrCl) of 60 L/wk/1.73 m2 or greater and a Kt/V of 2.0 or greater as peritoneal dialysis (PD) adequacy standards.
