Ghrelin Attenuates Sepsis-induced Acute Lung Injury and Mortality in Rats

American Journal of Respiratory and Critical Care Medicine Vol 176. pp. 805-813, (2007)

Our study has shown that plasma levels of ghrelin, a stomach-derived peptide, are significantly reduced in sepsis, and that ghrelin administration improves organ blood flow via a nuclear factor (NF)-kB-dependent pathway. However, it remains unknown whether ghrelin has any protective effects on severe sepsis-induced acute lung injury (ALI) and, if so, whether inhibition of NF-kB plays any role in it.

Corticosteroid-induced myopathy mimicking therapy-resistant asthma

Annals of Allergy, Asthma and Immunology, Volume 99, Number 4, October 2007 , pp. 371-374(4)

Therapy-resistant asthma is an important clinical problem. However, before considering asthma truly therapy resistant, it is essential to exclude diagnoses that may masquerade as therapy-resistant asthma, such as vocal cord dysfunction and recurrent aspiration, as well as factors related to loss of asthma control, including poor compliance, exposure to allergens, and sinusitis. Corticosteroid-induced myopathy may be an unrecognized but potentially important consideration in both settings.

How much of a primary care nurse’s time is spent on those with respiratory disease A pilot study

Primary Care Respiratory Journal Volume 16 Issue 5 October 2007 Pages 319-320

A pilot study was undertaken to assess the respiratory component of primary care nurses’ working time. 13 nurses were interviewed and 10 completed a diary during one working week. The nurses spent a mean 6.6% of their time caring for those with respiratory disease and were of the opinion that during this time they undertook 68% of the management of long term respiratory illness in the practices. More time was spent with those with asthma than with other respiratory conditions and the nurses felt that they were appropriately trained for the tasks undertaken. However, with more training they felt that they could undertake more basic care of those patients with COPD, and more advanced care of those patients with asthma.

Currently Available Cough Suppressants for Chronic Cough

Lung 0341-2040 10.1007/s00408-007-9030-1

Chronic cough is a common symptom but only a fraction of patients seek medical attention. Addressing the causes of chronic cough may lead to control of cough; however, this approach is not always successful since there is a certain degree of failure even when the cause(s) of cough are adequately treated; in idiopathic cough, there is no cause to treat. Persistent cough may be associated with deterioration of quality of life, and treatment with cough suppressants is indicated.

Determining the Clinical Probability of Deep Venous Thrombosis and Pulmonary Embolism

Southern Medical Journal. 100(10):1015-1021, October 2007

Deep venous thrombosis and pulmonary embolism are potentially life-threatening problems that present diagnostic challenges. To employ objective diagnostic tests in an efficient, safe, and cost-effective manner, the clinical probability of these disorders should be estimated before testing. A number of clinical prediction rules are available for suspected deep venous thrombosis, while there are three major prediction rules available for estimating the probability of pulmonary embolism. Recent modifications of the Wells score for deep venous thrombosis simplify its use. Although the Wells score for pulmonary embolism is commonly used, two other rules are useful for this disorder as well. This review summarizes the clinical prediction rules and gives recommendations about their application.

Clinical utility of vascular endothelial growth factor in diagnosing malignant pleural effusions

Acta Oncologica, Volume 46, Issue 7 2007 , pages 1004 - 1011

While the early diagnosis of cancer has been fully respected, it is still however often difficult for clinicians to confirm malignant pleural effusions (PE), which essentially indicate the end-stage cancer. It has now been demonstrated that vascular endothelial growth factor (VEGF) is a pivotal angiogenesis factor and associated with tumor growth and metastasis. The aim of this study was then to assess the diagnostic performance of VEGF in malignant PE.

Fine airborne urban particles PM2 5 sequester lung surfactant and amino acids from human lung lavage

Am J Physiol Lung Cell Mol Physiol 293: L1053-L1058, 2007

Components of surfactant act as opsonins and enhance phagocytosis of bacteria; whether this process occurs with atmospheric fine particles has not been shown. We have studied the interactions of fine particles (urban PM2.5) and surfactant removed from normal human lungs by lavage, using a surface analysis technique. The aim was to identify which of the chemical components of brochoalveolar lavage (BAL) deposit on the surfaces of urban PM2.5. Deposition of surfactant components on urban PM2.5 surfaces was reported in previous studies, but molecular identification and relative quantification was not possible using simple data analysis.

Vena caval filters for the prevention of pulmonary embolism

Cochrane Database of Systematic Reviews 2007 Issue 3

Pulmonary emboli can have potentially fatal consequences. Inferior vena caval filters are metal alloy devices that mechanically trap fragmented thromboemboli from the deep leg veins en route to the pulmonary circulation. Filters in current clinical use are designed to be introduced (and in the case of retrievable filters, removed) percutaneously. Although their deployment seems of theoretical benefit, their clinical efficacy and adverse event profile is unclear.

CpG oligonucleotide activates Toll-like receptor 9 and causes lung inflammation in vivo

Respiratory Research 2007, 8:72

Bacterial DNA containing motifs of unmethylated CpG dinucleotides (CpG-ODN) initiate an innate immune response mediated by the pattern recognition receptor Toll-like receptor 9 (TLR9). This leads in particular to the expression of proinflammatory mediators such as tumor necrosis factor (TNF-alpha) and interleukin-1beta (IL-1beta). TLR9 is expressed in human and murine pulmonary tissue and induction of proinflammatory mediators has been linked to the development of acute lung injury. Therefore, the hypothesis was tested whether CpG-ODN administration induces an inflammatory response in the lung via TLR9 in vivo.

Daily functioning of dyspnea self-esteem and physical self in patients with moderate COPD before during and after a first inpatient rehabilitation program

Disability & Rehabilitation, Volume 29, Issue 22 2007 , pages 1671 - 1678

Inpatient rehabilitation improves dyspnea and increases self-esteem between admission and discharge in patients with moderate chronic obstructive pulmonary disease (COPD). Some researchers nevertheless argue that the changes may be due to nursing effects and thus that scores will decrease quickly at home after discharge. This study assessed the change in dyspnea, self-esteem and physical self mean scores and stability in patients with moderate COPD during three consecutive four-week periods: at home, during an inpatient rehabilitation program, and again at home post-discharge.

Influence of Gender and Age on Upper Airway Length During Development

PEDIATRICS Vol. 120 No. 4 October 2007, pp. e1028-e1034

Obstructive sleep apnea has a strong male predominance in adults but not in children. The collapsible portion of the upper airway is longer in adult men than in women (a property that may increase vulnerability to collapse during sleep). We sought to test the hypothesis that in prepubertal children, pharyngeal airway length is equal between genders, but after puberty boys have a longer upper airway than girls, thus potentially contributing to this change in apnea propensity.

Lung Transplantation for Idiopathic Pulmonary Fibrosis

Ann Thorac Surg 2007;84:1121-1128

Outcomes of lung transplantation for idiopathic pulmonary fibrosis (IPF) are thought to be worse than those for other indications, although the reasons are unknown. In addition, the choice of single versus double lung transplantation is unclear. To guide decision-making, we (1) compared survival of patients receiving transplantation for IPF with survival of patients receiving transplantation for non-IPF diagnoses, (2) identified risk factors for mortality after transplantation for IPF, and (3) ascertained whether double lung transplantation for IPF confers a survival advantage.

Sildenafil for pulmonary hypertension in neonates

Cochrane Database of Systematic Reviews 2007 Issue 3

Persistent pulmonary hypertension in neonates (PPHN) is associated with high mortality. Currently, the therapeutic mainstay for PPHN is assisted ventilation and administration of inhaled nitric oxide (iNO). However, nitric oxide is costly and may not be appropriate in resource-poor settings. Approximately 30% of patients fail to respond to iNO. High concentrations of phosphodiesterases in the pulmonary vasculature has led to the use of phosphodiesterase inhibitors such as sildenafil or milrinone.

Ipsilateral reexpansion pulmonary edema after drainage of a spontaneous pneumothorax: a case report

Journal of Medical Case Reports 2007, 1:107 1752-1947

We report a case of ipsilateral reexpansion pulmonary edema occurring after the insertion of a chest tube in a patient with spontaneous pneumothorax. The patient received supplemental oxygen via a non-rebreather face mask to compensate for hypoxemia. 24 hours after the acute event, the patient recovered completely without residual hypoxemia. Reexpansion pulmonary edema after the insertion of a thoracic drainage for pneumothorax or pleural effusion is a rare complication with a high mortality rate up to 20%. It should be considered in case of hypoxemia following the insertion of a chest tube. The exact pathophysiology leading to this complication is not known. Risk factors for reexpansion pulmonary edema should be evaluated and considered prior to the insertion of chest tubes. Treatment is supportive.

Pneumonia Caused By Sewage Aspiration

The Internet Journal of Anesthesiology. 2007. Volume 14 Number 1

Aspiration is defined as entry of a foreign substance, solid or liquid, into the respiratory tract or inhalation of fumes and vapors. Aspiration pneumonia is caused by a direct chemical insult due to the aspirated material or by a primary or secondary bacterial infection. A three-year-old, 15 kg male patient fell into sewage accidentally and was brought to our hospital. His body was all covered with sewage. Sewage was aspirated and tracheal intubation was performed. 250 ml of fluid was aspirated at nasogastric and intubation tube. Respiratory and cardiopulmonary support and antibiotics were immediately started. After 15 days, he was sent to service with stable vital signs. This is a report on a pediatric patient ICU therapy for aspiration pneumonia.

Magnesium sulfate for persistent pulmonary hypertension of the newborn

Cochrane Database of Systematic Reviews 2007 Issue 3

Persistent pulmonary hypertension of the newborn (PPHN) occurs in approximately 1.9 per 1000 newborns and may be more frequent in developing countries. There is strong evidence for the use of inhaled nitric oxide (iNO) and extra corporeal membrane oxygenation (ECMO) in the treatment of PPHN. However, many developing countries do not have access or the technical expertise required for these expensive therapies. Magnesium sulfate is a potent vasodilator and hence has the potential to reduce the high pulmonary arterial pressures associated with PPHN. If magnesium sulfate were found to be effective in the treatment of PPHN, this could be a cost effective and potentially life-saving therapy.

Association between candidate genes and lung function growth in Chinese asthmatic children

Clinical & Experimental Allergy, Volume 37, Number 10, October 2007 , pp. 1480-1486(7)

Asthma is caused by a complex interaction between multiple candidate genes and environmental factors. The Childhood Asthma Management Program reported lung function decline in a significant proportion of Caucasian asthmatic children, but such a relation has not been studied in other populations. Our group recently reported that interleukin-13 (IL13), interleukin-4 receptor-α and thymus and the activation-regulated chemokine interacted to influence asthma and raised plasma total IgE.

Respirology Volume 12 Issue 5 Page 740-743, September 2007

Endothelin-1 (ET-1), a potent vasoconstrictor peptide produced by endothelial cells, has been implicated in the dysfunction of various organs. To determine the role of ET-1 in acute lung injury (ALI) and ARDS, ET-1 levels were measured in epithelial lining fluid (ELF) and plasma obtained from patients with ALI/ARDS.

Radiological Progression and Mortality among Silica Flour Packers A Longitudinal Study

Inhalation Toxicology, Volume 19, Issue 12 September 2007 , pages 1011 - 1017

There are few longitudinal studies that investigated the radiological progression of silicosis among different occupational groups. Inhalation exposure to very high levels of crystalline silica can lead to acute silicosis. This longitudinal study was designed to determine association between mortality and radiological progression among individuals with rapidly progressive silicosis. Twenty-three subjects with silicosis had previously worked in the same stone-grinding factories, where they had been exposed to high airborne concentrations of silica powder dust. The diagnosis of rapidly progressive form of silicosis was made according to the National Institute for Occupational Safety and Health definition.
