Thoracic trauma in children.

Isolated thoracic trauma is rare in children. Because of their small body size, the trauma often also affects other spaces, such as the abdomen and head, and these coexistences significantly increase the rate of mortality. However, in isolated thoracic traumas, the children can quickly recover if they can survive the initial period of trauma.

A novel approach for ventilation with Aintree catheter during rigid bronchoscopy: A non-ventilated case report.

Herein, we present a novel method to overcome difficult ventilation in a patient with a carinal tumor. After induction of anesthesia, we observed difficult ventilation due to obstruction of the right main bronchus as a result of herniation of the tumor mass arising from the left bronchial stump. Traditional lung ventilation techniques were not an option under these conditions.

Emergency department presentation of hemoptysis due to nail gun injury.

Nail guns are cheap and easy-to-access devices that are common in the industry and personal use and are widely used by untrained people. Life-threatening injuries may occur after a self-accident due to the use of these devices. We report the case of a 47-year-old man who had hemoptysis due to a lung parenchymal injury after nail gun use.

The role of thoracic trauma in inflammatory responses, apoptosis and bacterial translocation following multiple traumas.

Background: Blunt chest trauma and its complications are commonly encountered in emergency medicine. Herein, we used a rat model to investigate the role of thoracic trauma in inflammation, apoptosis and bacterial translocation following multiple traumas.

Methods: Ninety Wistar rats were divided equally into nine groups.

Elastofibroma dorsi: Review of eight cases.

Purpose: Elastofibroma dorsi (ED) is a rare, benign soft tissue tumor arising from connective tissue and usually found in the subscapular region. We conducted this retrospective study to contribute to a better understanding of this tumor, the pathogenesis of which is still unclear.

Methods: We reviewed the medical records of eight patients treated for ED at our institution between 2003 and 2008.

Efficiency of lornoxicam in lung and trachea injury caused by peroxynitrite.

Peroxynitrite is involved in the pathogenesis of pulmonary diseases such as asthma, occupational pulmonary diseases and acute respiratory distress syndrome (ARDS) due to excessive production of nitric oxide or superoxide or both. Lornoxicam, a new oxicam derivative, is a potent anti-inflammatory agent. In this study, we evaluated the role of lornoxicam in a peroxynitrite-induced pulmonary and tracheal injury model by measuring myeloperoxidase (MPO) activity, malondialdehyde (MDA) and 3-nitrotyrosine (3-NT) levels in lung tissue and bronco-alveolar lavage fluid.

Oleic acid-induced lung injury in rats and effects of caffeic acid phenethyl ester.

Caffeic acid phenethyl ester (CAPE) is a phenolic antioxidant and is an active anti-inflammatory component of honeybee propolis. The authors evaluated the effects of CAPE on oxidative stress and lung damage in an oleic acid (OA)-induced lung-injury model. Rats were divided into 5 groups as sham, OA, CAPE, pre-OA-CAPE, and post-OA-CAPE.

Effects of caffeic acid phenethyl ester on lipopolysaccharide-induced lung injury in rats.

Extracts of propolis, a natural beehive product, have been known for centuries to have a variety of beneficial medical properties, among which their anti-inflammatory effect is a major one. Caffeic acid phenethyl ester (CAPE), an active propolis component, has antimicrobial, anti-inflammatory, antioxidant, carcinostatic and immunomodulatory properties. In this study, we aimed to investigate the efficacy of CAPE in endotoxin-induced lung injury in rats.

The influence of iloprost on acute lung injury induced by hind limb ischemia-reperfusion in rats.

The local ischemia-reperfusion (I/R) process gains a systemic nature and affects distal organs. The remote effects of I/R are most frequently observed in the lungs and pulmonary damage may vary from acute lung injury with mild dysfunction to severe respiratory failure or the acute respiratory distress syndrome. In this hind limb I/R induced experimental lung injury model two groups of rats as IR and ILO were determined.

Inhibition of poly(ADP-ribose) polymerase attenuates lung tissue damage after hind limb ischemia-reperfusion in rats.

The objective of this study was to investigate the effects of 3-aminobenzamide (3-AB) on tissue damage in lung after hind limb ischemia-reperfusion (I/R), by assessing blood biochemical assay and histopathological analysis. Thirty-five adult Wistar rats were divided into five groups. After application of anaesthesia both hind limbs were occluded with tourniquets.

Rho-kinase (ROCK-1 and ROCK-2) upregulation in oleic acid-induced lung injury and its restoration by Y-27632.

The possible contribution of Rho/Rho-kinase signalling in oleic acid (100 mg kg-1, i.v., for 4 h)-induced lung injury was investigated in rats.

Effects of N-acetylcysteine on oxidant-antioxidant balance in oleic acid-induced lung injury.

The antioxidant and anti-inflammatory properties of N-acetylcysteine has been documented in many experimental lung injury models. Because intravenous injection of oleic acid induces histopathologic changes similar to those seen in human acute lung injury or acute respiratory distress syndrome, the authors evaluated the effects of N-acetylcysteine (NAC) on oxidative stress and lung damage in an oleic acid (OA)-induced lung injury model. Thirty-five rats were divided into 5 groups as sham, NAC, OA, pre-OA-NAC, and post-OA-NAC.

N-acetylcysteine inhibits peroxynitrite-mediated damage in oleic acid-induced lung injury.

Since oleic acid (OA) induces morphologic and cellular changes similar to those observed in human acute lung injury (ALI) and acute respiratory distress syndrome, it has become a widely used model to investigate the effects of several agents on pathogenesis of lung injury. The antioxidant and anti-inflammatory properties of N-acetylcysteine (NAC) has been documented in many lung injury models. In this study, we evaluated the role of NAC in an OA-induced lung injury model by measuring myeloperoxidase (MPO) activity, malondialdehyde (MDA) and 3-nitrotyrosine (3-NT) levels in lung tissue.

The protective effect of N-acetylcysteine on apoptotic lung injury in cecal ligation and puncture-induced sepsis model.

Apoptotic loss of parenchymal cells may lead to organ dysfunctions in critically ill patients with septic states. As an antioxidant, the protective effects of N-acetylcysteine (NAC) are documented in many experimental and clinical studies. In this experimental study, we investigated the role of chronically used NAC in septic lung injury on a cecal ligation and puncture (CLP) model.

A review of 24 patients with bronchial ruptures: is delay in diagnosis more common in children?

Objective: Bronchial ruptures due to blunt chest traumas are rarely encountered injuries. Because they occur seldom in pediatric age groups, even total ruptures of bronchi can be overlooked in the absence of accompanying lesions. This condition may result in a delay of diagnosis that consequently leads to irreversible septic changes in the lungs, which make resections unavoidable.

Poly(Adp-ribose) synthetase inhibition prevents lipopolysaccharide-induced peroxynitrite mediated damage in diaphragm.

Although the precise mechanism by which sepsis causes impairment of respiratory muscle contractility has not been fully elucidated, oxygen-derived free radicals are thought to play an important role. In our experimental study, the effects of poly(ADP-ribose) synthetase (PARS) inhibition on the diaphragmatic Ca(2+)-ATPase, malondialdehyde (MDA), and 3-nitrotyrosine (3-NT) levels and additionally histopathology of the diaphragm in lipopolysaccharide (LPS)-induced endotoxemia are investigated.Thirty-two male Wistar rats, weighing between 180-200 g were randomly divided into four groups.
