BACKGROUND: The act of swallowing after gastric pull-up esophagectomy has not been thoroughly investigated. The aim of this study was to evaluate deglutition in the esophageal remnant and in the gastric conduit in patients who have undergone this operation.METHODS: The residual radionuclide activity was measured 15 seconds after a swallow in the esophageal remnant and at intervals up to a maximum

OBJECTIVE: Pharyngeal reflux after a gastric pull-up esophagectomy may cause aspiration. This study evaluates acid exposure to the esophageal remnant and to the pharynx after gastric pull-up esophagectomy and evaluates the impact of additional dissection of the esophagus that is necessary for neck anastomoses versus no neck exploration and proximal chest anastomoses.METHODS: Forty-seven patients h

BACKGROUND: It has been suggested that endoscopic grading of the gastroesophageal flap valve is a good predictor of the reflux status.METHODS: To test this hypothesis, 268 symptomatic patients underwent endoscopic grading of the gastroesophageal valve using Hill's classification, with grades I through IV. Esophageal acid exposure, lower esophageal sphincter characteristics, and the degree of esoph

BACKGROUND: Screening patients with columnar metaplasia of the oesophagus for adenocarcinoma is controversial owing to the low cancer incidence and diverging opinions as to whether screening improves the prognosis of these patients. Our aim was to evaluate a screening program for adenocarcinoma in patients with columnar metaplasia in the oesophagus, with focus on cancer incidence and costs.METHODS

Esophagectomy is considered a high-risk procedure in patients aged 70 years or older. This study evaluates the impact of two age groups (younger than 70 and 70 years or older) on clinical outcome and long-term survival rates following this procedure. This prospective study included survival analysis and clinical evaluations at 3, 6, and 12 months after esophagectomy. All esophagectomy patients und

The prevalence of anastomotic strictures in esophageal anastomoses provides us with limited information about the anastomotic healing process. This prospective study evaluates the exact esophageal anastomotic diameters in 256 patients who underwent esophagectomy and esophagogastrostomy without pyloroplasty (n = 107) or total gastrectomy and Roux reconstruction (n = 149). No perioperative chemoradi

This article examines the legal scope and pressing issues of applying the privileges and immunities of the representations of states to international organizations. The content of the privileges and immunities of state’s representations is analyzed. The pressing issues of the application of privileges and immunities of representations of states to international organizations are deliberated, and a

Intra- and extracellular levels of magnesium and potassium were determined in 16 subjects with insulin-dependent type I diabetes mellitus (IDDM) and 30 healthy controls. Subjects with IDDM had lower levels of magnesium in muscle biopsies (p less than 0.001), plasma (p less than 0.001), and mononuclear cells (p less than 0.05), and higher urinary excretions of magnesium (p less than 0.01), and lowe

Magnesium and potassium concentrations were determined in plasma, erythrocytes and urine collected during 24 h, and in percutaneous muscle biopsies obtained in 30 healthy subjects. Magnesium was also analyzed in mononuclear cells. Men, compared to women, showed a higher urinary excretion of magnesium (p less than 0.05). The magnesium contents in mononuclear cells correlated significantly with the Magnesium and potassium concentrations were determined in plasma, erythrocytes and urine collected during 24 h, and in percutaneous muscle biopsies obtained in 30 healthy subjects.

Magnesium and potassium were analyzed in plasma, erythrocytes, and urine collected during 24 h and in muscle biopsies from 25 subjects with insulin-dependent, type I diabetes mellitus (IDDM). Magnesium was also measured in mononuclear cells. The results were compared with those of 28 healthy controls, and were also correlated with the degree of diabetic control as estimated by analysis of the leve

In this study analysis of magnesium in mononuclear cells was compared to that in muscle in patients and healthy controls. Mononuclear cell concentrations of magnesium expressed as nmol/mg cell protein correlated significantly with muscle biopsy concentrations of magnesium (r = 0,68; p less than 0,001). Hence, we suggest that analyzing of magnesium in mononuclear cells could be an easy and convenie

H-kininogen (high-molecular-mass kininogen, HK) is the precursor of the vasoactive peptide hormone bradykinin (BK). Previous work has demonstrated that HK binds to Streptococcus pyogenes through M-proteins, fibrous surface proteins and important virulence factors of these bacteria. Here we find that M-protein-expressing bacteria absorb HK from human plasma. The HK bound to the bacteria was found t
