BACKGROUND Belching has been proposed as a major mechanism underlying acid gastro-oesophageal reflux in normal subjects. However, the presence of oesophageal gas has not been measured directly but only inferred from manometry. AIMS To investigate, using intraluminal electrical impedance, the patterns of gas and liquid reflux during transient lower oesophageal sphincter (LOS) relaxations, the ...

OBJECTIVE To systematically review published literature describing the association between reflux and upper airway symptoms in children. DESIGN Structured MEDLINE search of English-language articles published since 1966. SUBJECTS We selected articles examining reflux in conjunction with stridor, apnea, sudden infant death syndrome, life-threatening events, and laryngomalacia. Studies that f...

We analyzed the frequency of vesicoureteral reflux and the factors that favor its appearance after kidney transplantation in pediatric patients. This retrospective analysis examined the prevalence of post-transplant vesicoureteral reflux in a total of 181 kidney transplants performed in children at our center between 1978 and 2004. In patients who required corrective surgery for this problem, w...

Valvular tumors and tumor-like lesions may have similar morphological and clinical characteristics, and may place the patients at a high risk of stroke in different ways. From January 2004 to June 2008, 11 patients underwent surgery for a suspected valvular tumor. Valvular tumor and tumor-like lesions accounted for 0.32% of adult cardiac operations. Five (45.5%) valvular lesions were papillary ...

Abstract Background Benign prostatic hyperplasia (BPH) is inescapable with aging and can cause lower urinary tract symptoms, worsening the quality of life. New pathophysiologic mechanisms BPH development are currently under study to modulate its management. The valvular destruction spermatic veins (varicoceles development) incurs a testicular-prostatic hydrostatic pressure gradient, which conve...

BACKGROUND/AIMS Gastroesophageal reflux disease (GERD) may occur with acid, bile or in a mixed form. Endoscopic injury and mucosal metaplasia are a known sequelae to pathological GERD. The aim of the study was to determine the contribution of acid and duodenogastroesophageal reflux to endoscopic severity in patients with GERD and Barrett's esophagus (BE). MATERIALS AND METHODS Ninety-one pati...

BACKGROUND In middle income countries, the burden of rheumatic heart disease (RHD) remains high, but the prevalence of other heart valve diseases may rise as the population life expectancy increases. Here, we compared population-based data on surgical procedures to assess the relative importance of causes of heart valve disease in Salvador, Brazil. METHODOLOGY/PRINCIPAL FINDINGS Medical chart...

BACKGROUND Patients with end-stage renal disease (ESRD) are at increased risk for tissue calcifications as a result of deranged mineral metabolism. We tested the hypothesis that valvular calcification is a marker of atherosclerosis in patients with ESRD. METHODS Echocardiography was performed in 92 patients undergoing peritoneal dialysis with no background atherosclerotic vascular complicatio...

OBJECTIVE To describe the natural history of intraocular pressure (IOP) within the first 30 minutes after intravitreal injection of triamcinolone acetonide (TA). DESIGN Prospective, interventional, consecutive case series. PARTICIPANTS Thirty-eight consecutive patients who met inclusion and exclusion criteria and underwent intravitreal injection of 0.1 ml (4 mg) of TA were studied. METHOD...

Preoperative venous duplex scanning has revealed unexpected deep venous incompetence in patients with apparently only varicose veins. Acting on the hypothesis that the deep vein reflux was secondary to deep vein dilation caused by reflux volume, the following was done. Between July 1990 and April 1993, 29 limbs in 21 patients (16 females) were examined by color-flow duplex imaging to determine ...
