BACKGROUND: Deep sedation is increasingly used for endoscopy. The impact of sedation level on hemodynamic status, oxygenation, and aspiration risk is incompletely described. AIMS: To describe the incidence of intraprocedural cough, hemodynamic changes, oxygen desaturation, and their relationship to clinical factors and sedation level. METHODS: Detailed prospective recordings of hemodynamic ...

Many ad hoc fasting guidelines for pre-anesthetic patients prohibit gum chewing. We find no evidence that gum chewing during pre-anesthetic fasting increases the volume or acidity of gastric juice in a manner that increases risk, nor that the occasional associated unreported swallowing of gum risks subsequent aspiration. On the contrary, ...

The purpose of this study was to identify the incidence and potential risk factors for cardiac arrest upon induction of anesthesia in children with cardiomyopathy ...

CONTEXT: Cases of ischaemic brain damage have been reported in relatively healthy patients undergoing shoulder surgery in the beach chair position. Unrecognised cerebral hypoperfusion may have contributed to these catastrophic events, indicating that routine anaesthesia monitoring may not suffice.

In cystic fibrosis (CF), changes in fatty acid (FA) composition of serum phospholipids (PL) and cell membranes can account, in part, for the inflammatory state of the disease. The severity of the genotype is known to correlate with the degree of FA changes. Liver diseases, such as cholestasis and cirrhosis ...

Antibiotic therapy is thought to improve lung function in patients with cystic fibrosis (CF) by decreasing neutrophil-derived inflammation.

Our aim was to determine whether more histologically ...

Small intestine bacterial overgrowth (SIBO) has been reported in cystic fibrosis (CF) patients. However, the potential link to intestinal inflammation has not been studied so far. Therefore, we aimed to assess whether SIBO correlates with intestinal inflammation in CF patients. As a preliminary study, we assessed whether calprotectin is detectable ...

The aim of this study was to investigate whether the non-invasive serum marker FibroTest-ActiTest (FT-AT) reliably predicts the histological stage of fibrosis and/or activity, and decreases the need for a liver biopsy. Twenty-five children with naïve chronic hepatitis B were analyzed for haptoglobin, alpha2-macroglobulin, apolipoprotein A1, bilirubin, gamma-glutamyl transferase, and ...

Allergic bronchopulmonary aspergillosis (ABPA) is a frequent complication in cystic fibrosis patients.

The aim of this study was to analyze the added value of two recombinant antigens, rAspf4 and rAspf6, associated with the detection of ...

In cystic fibrosis (CF), airway inflammation causes an increased production of reactive oxygen species, responsible for degradation of cell membranes. During this process, volatile organic compounds (VOCs) are formed. Measurement of VOCs in exhaled breath of CF patients may be useful for the assessment of airway inflammation. This study investigates ...

Non-invasive markers of fibrosis have been used to diagnose liver fibrosis in a variety of diseases. Hyaluronic acid (HA) and collagen IV (C-IV) levels were measured in the sera of patients from an endemic area for schistosomiasis in Brazil to diagnose and to rank the intensity of liver fibrosis. Seventy-nine ...

Six of the CFs, but none of the IBRs ...

BACKGROUND AND AIM: Nephrogenic systemic fibrosis (NSF) is a highly debilitating disorder primarily affecting the skin, but also other organ compartments. So far, it has only occurred in patients suffering from acute or chronic renal failure, with almost all of them having been exposed to gadolinium-based contrast agents (GBCA). The ...

Pulmonary exacerbations are a major cause of morbidity in cystic fibrosis (CF) and likely contribute to lung function decline. Exacerbations are often associated with characteristic airway bacteria [CF related bacteria (CFRB)]. However, some patients do not have CFRB detected by culture during exacerbations. We sought to determine the proportion of ...

BACKGROUND: There is significant debate on the influence of inflammatory mucosal disease on paranasal sinus pneumatization (PSP) and temporal bone pneumatization (TBP) in cystic fibrosis patients (CF).
