Thermographic Microstructure Monitoring in Electron Beam Additive Manufacturing.

To reduce the uncertainty of build performance in metal additive manufacturing, robust process monitoring systems that can detect imperfections and improve repeatability are desired. One of the most promising methods for in situ monitoring is thermographic imaging. However, there is a challenge in using this technology due to the difference in surface emittance between the metal powder and solidified part being observed that affects the accuracy of the temperature data collected.

Mating disruption of Spilonota ocellana and other apple orchard tortricids using a multispecies reservoir dispenser.

Background: A new mating disruption formulation for population control of a wide range of tortricid pests, including Spilonota ocellana, was tested in Swedish apple orchards during 2012-2013. Owing to the characteristics of the local agricultural landscape, mating disruption was evaluated in isolated orchards rather than through an area-wide approach. Parameters such as trap shutdown, communication disruption in field cages, damage level and dispenser emission were measured as efficacy indicators.

Effect of palate re-repairs and hynes pharyngoplasties on pediatric airways: an analysis of preoperative and postoperative cardiorespiratory sleep studies.

OBJECTIVES : To determine whether Sommerlad palate re-repairs and Hynes pharyngoplasties cause obstructive sleep apnea/hypopnea or increased upper airway resistance. DESIGN : Prospective before-and-after study. SETTING : Tertiary cleft unit.

Chest physiotherapy during anesthesia for children with cystic fibrosis: effects on respiratory function.

Background: Physiotherapists sometimes use elective surgical procedures for children with cystic fibrosis as an opportunity to perform physiotherapy treatments during anesthesia. These treatments theoretically facilitate direct endotracheal airway clearance and compensate for any post-operative respiratory deterioration related to the anaesthetic and surgery. MATERIALS, PATIENTS, AND METHODS: Children were randomized either to receive physiotherapy or not following anesthesia and intubation.

Monitoring metal-fill in a lost foam casting process.

The lost foam casting (LFC) process is emerging as a reliable casting method. The metal-fill profile in LFC plays an important role among several factors that affect casting quality. The metal-fill profile is in turn affected by several factors.

The Chrispin-Norman score in cystic fibrosis: doing away with the lateral view.

The Chrispin-Norman chest radiograph scoring (CNS) system is widely used to assess respiratory disease progression in cystic fibrosis (CF). Frontal and lateral chest radiographs were performed. The present authors developed a modified CNS, which obviates the need for the lateral film.

The lung in multi-system disease.

Lung involvement in multi-system disease is rare in children. When it does occur it is associated with significant morbidity and mortality. Auto-immune diseases such as systemic lupus erythematosis, scleroderma and acute rheumatic disease can cause major lung pathology.

Growth and lung function in Asian patients with cystic fibrosis.

Background: The incidence of cystic fibrosis (CF) in Asians is rare. How these patients fare in terms of morbidity and mortality in the UK compared to their non-Asian peers is not well documented.

Aims: To retrospectively study annual reviews of 31 Asian CF patients from three London paediatric CF centres.

Systemic diseases and the lung.

Systemic diseases affecting the lung are fortunately relatively rare in paediatric practice. A number of conditions do, however, cause significant respiratory complications, which can result in serious morbidity and mortality in this age group. These include connective tissue disorders such as systemic lupus erythematosus, dermatomyositis and scleroderma, inherited connective tissue disorders such as Ehlers-Danlos and Marfan's syndrome, lysosomal storage disorders such as mucopolysaccharidoses, familial dysautonomia, Langerhans cell histocytosis, pulmonary lymphangiomatosis, sarcoidosis and sickle cell disease.

Anti-inflammatory therapy in cystic fibrosis.

Inflammation plays a major role in the pathophysiology of lung disease in CF. This response is probably triggered primarily as a reaction to the inability of the affected lung to resist the invasion of the most common bacterial pathogens seen in this disease, namely, Staphylococcus aureus, Haemophilus influenzae and Pseudomonas aeruginosa. Debate continues as to whether there may or may not be a pre-inflammation of the lungs as part of the basic functional defect of CFTR.

Cystic fibrosis and Russell-Silver syndrome in a child with maternal isodisomy of chromosome 7.

A 6-year-old Asian girl was diagnosed with cystic fibrosis at 3 months of age, following investigations for failure to thrive. She had intrauterine growth retardation and continued to have restricted postnatal growth, despite adequate caloric intake and enzyme replacement therapy. Further investigations were initiated when she was 5 years old, as her growth was not responding to the usual treatment measures.

Congenital upper airway obstruction.

Most causes of upper airway obstruction are rare in the neonatal period and during infancy. They may, however, cause major respiratory problems either initially or during the first few weeks of life. It is important to recognise these problems at an early stage so that appropriate measures to overcome airway obstruction can be initiated, thus avoiding significant hypoxia-related complications.

Treatment of interstitial lung disease in children.

The treatment of interstitial lung disease in children depends on the nature of the underlying pathology. In approximately 50% of cases a specific aetiology can be found such as: chronic viral infection, an auto-immune process, sarcoidosis or alveolar proteinosis. In the remainder, the process is idiopathic and the pathological findings are based on the descriptive morphological features seen in the diagnostic lung biopsy.

The evolution of airway function in early childhood following clinical diagnosis of cystic fibrosis.

This study aimed to investigate the evolution of airway function in infants newly diagnosed with cystic fibrosis (CF). FEV(0.5) was measured soon after diagnosis (median age of 28 weeks) and 6 months later in subjects with CF and on two occasions 6 months apart (median ages of 7.

An alternative to lung transplantation.

Lung volume reduction surgery (LVRS) has been used increasingly in adults for treatment of breathlessness caused by severe emphysema.1 It is of particular benefit to patients with a heterogenous anatomic distribution of emphysema, with obvious target areas for resection,2 as it allows an improved chance of reclaiming function from surrounding compressed lung.3 We report on an 8-year-old male with obliterative bronchiolitis in whom LVRS has been used as a measure to significantly improve quality of life and avoid the immediate need for lung transplantation.

Primary pulmonary lymphangiectasis in a premature infant: resolution following intensive care.

Primary pulmonary lymphangiectasis is a rare disease, often described as fatal within the neonatal period. We report on an infant who developed severe bilateral chylous pleural effusions with computed tomography (CT) features of pulmonary lymphangiectasis. She recovered spontaneously with supportive treatment only.

Primary thoracoscopic treatment of empyema in children.

Objective: The optimal treatment of pediatric empyema remains controversial. The objective of this study is to compare the use of conventional management versus primary thoracoscopic drainage and decortication in children with empyema.

Methods: Conventional management has consisted of chest drain insertion under general anesthesia plus intravenous antibiotics.
