Use of a provocation test for objective assessment of dumping syndrome in patients undergoing surgery for duodenal ulcer

It is difficult to assess the incidence of dumping after various operations for duodenal ulcer on clinical grounds alone. An objective assessment of dumping has been made with the help of a provocation test. The test, using 50% hypertonic glucose solution labeled with radioactive Indium 113m was performed on 39 preoperative patients and 107 times on 72 patients after operation for duodenal ulcer. The dumping status of all the patients prior to surgery was asymptomatic after ordinary food as well as on test. Among the postoperative studies the clinical status was asymptomatic in 69, uncertain in 32 and six had dumping symptoms. On the basis of the symptoms on-test, the status was asymptomatic in 61, uncertain in 14 and 32 had dumping symptoms. The objective indices further defined the status as 70 asymptomatics, none uncertain and 37 confirmed dumpers and thereby completely abolished the uncertain group. All the objective measurements of the dumping provocation test have clearly differentiated those patients with from those without dumping symptoms. Patients with dumping symptoms on-test had a significantly greater fall in plasma volume, more rapid rates of gastric emptying and steeper rise in blood sugar after ingestion of hype...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
