Effects of N-acetylcysteine treatment in acute respiratory distress syndrome: A meta-analysis.
Authors: Zhang Y, Ding S, Li C, Wang Y, Chen Z, Wang Z Abstract Acute respiratory distress syndrome (ARDS) is a serious complication of acute lung injury. Severe systemic inflammation is the main cause of multiple organ dysfunction and high mortality. Removal of reactive oxygen species by anti-oxidants has been applied in clinical practice. N-acetylcysteine (NAC) is the most commonly used anti-oxidant. However, the benefit of anti-oxidant therapy was not consistently demonstrated by previous studies. In the present study, a meta-analysis was performed to evaluate the effects of NAC for adult patients with ARDS. The...

Late-onset Pompe disease in a 54 year-old sportsman with an episode of syncope: a case report.
Authors: Walczak-Galezewska M, Skrypnik D, Szulinska M, Musialik K, Skrypnik K, Bogdanski P Abstract Pompe disease is an extra-rare metabolic storage disease with deficiency of acid-alpha-glucosidase (GAA) enzyme activity, which leads to the pathologic accumulation of glycogen in target tissues (skeletal muscles, heart, brain). Clinical features and severity vary by the age of onset, rate of extent of organ involvement. In the late-onset Pompe disease (LOPD) form, essential cardiomyopathy seems to be uncommon. Muscles weakness and respiratory failure are the main symptoms of adult patient with Pompe disease. In pre...

Induction of reactive oxygen species: an emerging approach for cancer therapy
AbstractReactive oxygen species (ROS), a group of ions and molecules, include hydroxyl radicals ( ·OH), alkoxyl radicals, superoxide anion (O2·−), singlet oxygen (1O2) and hydrogen peroxide (H2O2). Hydroxyl radicals and alkoxyl radicals are extremely and highly reactive species respectively. Endogenous ROS are mainly formed in mitochondrial respiratory chain. Low levels of ROS play important roles in regulating biological functions in mammalian cells. However, excess production of ROS can induce cell death by oxidative damaging effects to intracellular biomacromolecules. Cancer cell death types induced ...

Pulmonary Dysfunction and Heart Failure
In patients with heart failure (HF), particularly in elderly patients, pulmonary dysfunction is frequent. There might be bidirectional interaction in between pulmonary dysfunction and HF. One is from HF to pulmonary dysfunction, possibly through the enlarged heart and pulmonary congestion in association with HF. The other is from pulmonary dysfunction and/or respiratory-control disorders associated with comorbid pulmonary diseases to HF. Among such comorbid pulmonary diseases, chronic obstructive lung disease (COPD) and sleep-disordered breathing (SDB) are particularly important in elderly patients with HF, since in genera...

Targeting fatty acid amide hydrolase as a therapeutic strategy for antitussive therapy
Cough is the most common reason to visit a primary care physician, yet it remains an unmet medical need. Fatty acid amide hydrolase (FAAH) is an enzyme that breaks down endocannabinoids, and inhibition of FAAH produces analgesic and anti-inflammatory effects. Cannabinoids inhibit vagal sensory nerve activation and the cough reflex, so it was hypothesised that FAAH inhibition would produce antitussive activity via elevation of endocannabinoids. Primary vagal ganglia neurons, tissue bioassay, in vivo electrophysiology and a conscious guinea pig cough model were utilised to investigate a role for fatty acid amides in modulati...

Determinants of diaphragm thickening fraction during mechanical ventilation: an ancillary study of a randomised trial
Ultrasonography of the diaphragm is the subject of a growing interest in the intensive care unit (ICU) setting [1–6]. Observing the diaphragm in its zone of apposition allows measurement of its thickness and computation of its thickening fraction (TFdi), which depends on diaphragmatic activity  and reflects the diaphragm work of breathing . A recent study showed that the TFdi correlated well with the endotracheal pressure variation generated by phrenic stimulation . This index was also proposed for clinical evaluation of diaphragm weakness to detect ventilator-induced diaphragmatic dysfunction (VIDD) and pre...

The Effect of Pulmonary Surfactant on the In Vitro Activity of Iclaprim Against Common Respiratory Bacterial Pathogens
The in vitro antimicrobial activity of iclaprim, a novel diaminopyrimidine, against common respiratory bacteria remained unchanged in the presence of pulmonary surfactant (Survanta ®) at concentrations that greatly antagonized the antimicrobial activity of daptomycin. These results indicate that iclaprim could be a potential treatment for pneumonia caused by susceptible and multidrug resistant bacteria. (Source: Diagnostic Microbiology and Infectious Disease)

Gastroesophageal reflux disease (GERD) is a common condition in infants. Symptoms from pathologic GERD include regurgitation, irritability when feeding, failure to thrive, and respiratory problems. Treatment typically starts with dietary modifications and postural changes. Antireflux medications may then be added. Indications for operative management in neonates and infants include poor weight gain, failure to thrive, acute life-threatening events, and continued respiratory symptoms. Laparoscopic Nissen fundoplication has become the standard of care for surgical treatment of children with GERD. In this procedure, the fundu...

Avian thermoregulation in the heat: resting metabolism, evaporative cooling and heat tolerance in Sonoran Desert songbirds [RESEARCH ARTICLE]
We examined thermoregulatory performance in seven Sonoran Desert passerine bird species varying in body mass from 10 to 70 g – lesser goldfinch, house finch, pyrrhuloxia, cactus wren, northern cardinal, Abert's towhee and curve-billed thrasher. Using flow-through respirometry, we measured daytime resting metabolism, evaporative water loss and body temperature at air temperatures (Tair) between 30 and 52°C. We found marked increases in resting metabolism above the upper critical temperature (Tuc), which for six of the seven species fell within a relatively narrow range (36.2–39.7°C), but which was c...

Primary lung cancer in Assiut University Hospitals: Pattern of presentation within four years (January 2011: December 2014)
Conclusions Knowing that the incidence of lung cancer increased globally in both male and female, the relatively lower male to female ratio when compared with other studies, may reflect at least an increasing in the lung cancer rates among female. Smoking still remains the major risk factor in pathogenesis of primary lung cancer. COPD could be considered an important respiratory disorder that tied to bronchogenic carcinoma risk. Interestingly, the incidence of adenocarcinoma surpassed that of squamous cell carcinoma. Unfortunately, presentation of the patient at later stages of illness was common.

Epidemiology and burden of HPV-related disease
Publication date: Available online 2 September 2017 Source:Best Practice & Research Clinical Obstetrics & Gynaecology Author(s): Beatriz Serrano, María Brotons, Francesc Xavier Bosch, Laia Bruni Human papillomavirus (HPV) infection is recognized as one of the major causes of infection-related cancer in both men and women. High-risk HPV types are not only responsible for virtually all cervical cancer cases but also for a fraction of cancers of the vulva, vagina, penis, anus, and head and neck cancers. Furthermore, HPV is also the cause of anogenital warts and recurrent respiratory papillomatosis. Des...

Cerebral Fat Embolism: Recognition, Complications, and Prognosis
AbstractFat embolism syndrome (FES) is a rare syndrome caused by embolization of fat particles into multiple organs including the brain. It typically manifests with petechial rash, deteriorating mental status, and progressive respiratory insufficiency, usually occurring within 24 –48 h of trauma with long-bone fractures or an orthopedic surgery. The diagnosis of FES is based on clinical and imaging findings, but requires exclusion of alternative diagnoses. Although there is no specific treatment for FES, prompt recognition is important because it can avoid unnecessary int erventions and clarify prognosis. Patien...
