BACKGROUND: Glomerulopathy is an increasingly identified complication in young patients with sickle cell disease (SCD). Hyperfiltration and albuminuria followed by declining glomerular filtration rates and eventual end-stage renal disease (ESRD) is assumed to be the typical progression of glomerular disease. There are only a few reported biomarkers to identify early-stage renal disease in SCD. PROCEDURES: We detail the renal profile of 101 children with SCD in Malawi and propose a novel urinary biomarker for the identification of early renal disease...

Intrinsic positive end-expiratory pressure (PEEP) and gas trapping are recognised hazards during ventilation of patients with airflow obstruction. Demonstration of these phenomena on conventional lung models using realistic ventilation settings is difficult. We describe an Intrinsic PEEP Model that is able to demonstrate dynamic gas trapping and intrinsic PEEP at realistic ventilation settings, and demonstrate its ability to develop intrinsic PEEP in a timeframe useful for teaching. The model uses a Heimlich valve to permit a lower resistance on inspiration than expiration...

Aim: <AbstractText>To study the most effective body position for Heimlich maneuver. Methods: A choking simulation manikin was connected to a laryngeal model of a child or an adult, and a differential pressure transducer recorded the airway pressure and waveform during the maneuver. A konjac jelly was placed on the larynx to mimic complete supralaryngeal obstruction. The maneuver (five successive compressions) was carried out six times each in standing, prone, and supine positions...

Blue whale sound production has been thought to occur by Helmholtz resonance via air flowing from the lungs into the upper respiratory spaces. This implies that the frequency of blue whale vocalizations might be directly proportional to the size of their sound-producing organs. Here we present a sound production mechanism where the fundamental and overtone frequencies of blue whale B calls can be well modeled using a series of short-duration (<1 s) wavelets. We propose that the likely source of these wavelets are pneumatic pulses caused by opening and closing of respiratory valves during air recirculation between the lungs and laryngeal sac...

OBJECTIVES: Drowning is one of the leading causes of death in children. Resuscitating a child following submersion is a high-pressure situation, and standard operating procedures can reduce error. Currently, the Resuscitation Council UK guidance does not include a standard operating procedure on pediatric drowning. The objective of this project was to design a standard operating procedure to improve outcomes of drowned children. METHODS: A literature review on the management of pediatric drowning was conducted...

BACKGROUND: Localizing small or deep pulmonary nodules or subsolid ground-glass opacities often is difficult during video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracoscopic surgery (RATS). This can result in larger resections or conversion to thoracotomy. The goal of this study is to evaluate the role of electromagnetic navigational bronchoscopic localization (ENBL) as a safe and accurate intraoperative method to localize small, deep, or subsolid nodules. METHODS: This is a single-institution, single-surgeon retrospective study of all patients (51) who underwent combined ENBL and resection of 54 nodules between May 2013 and August 2015...

A 14-year-old boy came to our outpatient department with pleuritic chest pain and dyspnea. He was found to have a loculated empyema on the right side. He was taken up for surgery and decortication was done. He developed air leak in the postoperative period. When the air leak did not settle until the 10(th) day, we decided to attach the atrium Pneumostat(™), a modified version of the Heimlich valve to his Intercostal drainage tube and sent him home. On further follow-up, his lung expanded, and ICD could be removed...

PURPOSE: Patients with thoracic malignancies often have more than one site of pulmonary, nodal or pleural disease within one hemithorax. In addition, large heterogeneous lesions may comprise distinct, mixed pathological entities. Histological analysis of these lesions can alter tumour staging and treatment options. We investigated the feasibility, safety and benefit of performing image-guided percutaneous lung biopsy (PLB) of two lesions in the same hemithorax at a single sitting. MATERIALS AND METHODS: Ten consecutive outpatients with two or more potential disease foci within the same hemithorax were analysed over a 15-month period...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS...

Burkitt lymphoma (BL) is the most common paediatric cancer in sub-Saharan Africa (SSA). Anthracyline-based treatment is standard in resource-rich settings, but has not been described in SSA. Children ≤18 years of age with newly diagnosed BL were prospectively enrolled from June 2013 to May 2015 in Malawi. Staging and supportive care were standardized, as was treatment with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) for six cycles. Among 73 children with BL, median age was 9·2 years (interquartile range 7·7-11·8), 48 (66%) were male and two were positive for human immunodeficiency virus...

The repopulation of abandoned areas in Angola after 27years of civil war led to a fast and extensive expansion of agricultural fields to meet the rising food demand. Yet, the increase in crop production at the expense of natural resources carries an inherent potential for conflicts since the demand for timber and wood extraction are also supposed to rise. We use the concept of ecosystem services to evaluate the trade-off between food and woody biomass. Our study area is located in central Angola, in the highlands of the upper Okavango catchment...

BACKGROUND: Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It may be treated with either needle aspiration or insertion of a chest tube. The former consists of aspiration of air with a syringe through a needle or an angiocatheter, usually through the second or third intercostal space in the midclavicular line. The chest tube is usually placed in the anterior pleural space passing through the sixth intercostal space into the pleural opening, turned anteriorly and directed to the location of the pneumothorax, and then connected to a Heimlich valve or an underwater seal with continuous suction...

Recent developments in capsule endoscopy have highlighted the need for accurate techniques to estimate the location of a capsule endoscope. A highly accurate location estimation of a capsule endoscope in the gastrointestinal (GI) tract in the range of several millimeters is a challenging task. This is mainly because the radio-frequency signals encounter high loss and a highly dynamic channel propagation environment. Therefore, an accurate path-loss model is required for the development of accurate localization algorithms...

A thorough understanding of the molecular details of the interactions between bacteria and host are critical to ultimately prevent disease. Recent technological advances allow simultaneous analysis of host and bacterial protein and metabolic profiles from a single small tissue sample to provide insight into pathogenesis. We used the chinchilla model of human otitis media to determine, for the first time, the most expansive delineation of global changes in protein and metabolite profiles during an experimentally induced disease...

BACKGROUND AND PURPOSE: Endothelin-1 (ET-1) is increased in patients with sickle cell disease and may contribute to the development of sickle cell nephropathy. The current study was designed to determine whether ET-1 acting via the ETA receptor contributes to renal injury in a mouse model of sickle cell disease. EXPERIMENTAL APPROACH: Adult, humanized HbSS (homozygous for sickle Hb) mice had increased ET-1 mRNA expression in both the cortex and the glomeruli compared with mice heterozygous for sickle and Hb A (HbAS controls)...
