Background/Objectives: In developing countries, spirometry has not been considered a part of routine medical check-up. The purpose of the study was to establish the usefulness of spirometry as a primary screening tool in detecting air flow obstruction (AFO) during routine medical check-up (RMC). Methods: This was a hospital based, retrospective, non-randomized case series study of 3696 participants, who presented to hospital for routine medical check-up. All subjects were assisted at the Pulmonary Medicine Department, from January 2003 till December 2008 who, having met other inclusion criteria, underwent spirometry. Data were analyzed using proportion, group means, standard deviations and …

Single Lung Ventilation In A Young Child For Repair Of Coarctation Of Aorta, Mohammad Hamid, Mansoor Ahmed Khan, Muneer Amanullah

Department of Anaesthesia

Single lung ventilation in small children is extremely challenging. In this case, a paediatric bronchial blocker was successfully inserted in a 19-month-old child to provide single lung ventilation using a modified insertion technique. It provided excellent working conditions during thoracotomy and our method of insertion may help in reducing the cost.

Osteopontin And Cadherin 11 Are Novel Mediators And Drug Targets For Chronic Lung Diseases, Daniel J. Schneider

Dissertations & Theses (Open Access)

Chronic lung diseases (CLDs) are a considerable source of morbidity and mortality and are thought to arise from dysregulation of normal wound healing processes. An aggressive, feature of many CLDs is pulmonary fibrosis (PF) and is characterized by excess deposition of extracellular matrix (ECM) proteins from myofibroblasts in airways. However, factors regulating myofibroblast biology are incompletely understood. Proteins in the cadherin family contribute epithelial to mesenchymal transition (EMT), a suggested source of myofibroblasts. Cadherin 11 (CDH11) contributes to developmental and pathologic processes that parallel those seen in PF and EMT. Utilizing Cdh11 knockout (Cdh11 -/-) mice, the goal of this …

The Role Of The Ras Superfamily Small G-Proteins In The Proinflammatory Environment Of Rhinovirus-Exposed Monocytic-Lineage Cells, Michael Schreiber

Lawrence University Honors Projects

Rhinoviral infections are a major cause of asthma exacerbations, and though productive rhinovirus infection occurs predominantly in the bronchial epithelial cells of the upper airway, monocytic-lineage cells are implicated in establishing the inflammatory microenvironment observed during rhinoviral asthma exacerbation. It has remained unclear whether small G-protein activation plays a role in establishing this inflammatory microenvironment. The small molecular- weight G-proteins are known to be activated in a variety of cell types upon exposure to a range of viruses. However, it is unclear if small G-protein activation during viral exposure is a byproduct of receptor attachment, is important for viral replication, …

Changing Po2licy: The Elements For Improving Childhood Asthma Outcomes, Anne Rossier Markus, Meagan Lyon, Sara J. Rosenbaum

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

Childhood asthma is a serious and chronic health issue that affects one in seven U.S. children and their families, compromising their health and quality of life and placing a heavy financial burden on families as well as an enormous strain on the health care system. Treating, managing, and ultimately preventing and reducing the burden of asthma represents a critical test of the ability of the U.S. health system – health insurers, clinical care providers, and public health agencies – to work together. Our investigation found that, as a country, we already know enough to act and improve life for the …

Program Evaluation For Tdap Immunization Standing Orders In A Birthing Hospital, Helen Crean Taugher

Doctor of Nursing Practice (DNP) Projects

Newborn infants are vulnerable to pertussis infections. Although the Advisory Committee on Immunization Practices (ACIP) recommends that babies begin their diphtheria, tetanus and acellular pertussis (DTaP) immunization series at two months of age, the minimum age for administration of the vaccine is six weeks of age (Centers for Disease Control [CDC], 2008). Young infants are at risk for whooping cough infection transmitted from parents, siblings and care-givers during the pre-vaccination period in the first two months of life, particularly pertussis transmitted from their mothers. Since the licensure of adult/adolescent formulations of tetanus, diphtheria and acellular pertussis (Tdap) vaccine in 2005, …
