Ruminococcus gnavus bacteremia: Literature review and a case report associated with acute flare of ulcerative colitis in an immunocompromised patient.

We present a case of bacteremia caused by Ruminococcus gnavus in an immunocompromised patient. R. gnavus is a Gram-positive strict anaerobe bacterium that forms chains.

β-Endorphins are not responsible for delayed gastric emptying of digestible solids after exercise in professional cyclists. A preliminary study.

Objective: It has been reported that professional cyclists had an accelerated solid gastric emptying which decreased by increasing the exercise intensity. That could be explained by a predominance of stress-dependent motility inhibitors such gastrointestinal hormones, neurotransmitters and or the predominance of the gastric inhibitory vagal motor circuit. The aim of this preliminary study was to evaluate the role of β-endorphins, inhibitors of gastric motility, in these findings.

Deep Phenotypic Characterisation of CTCs by Combination of Microfluidic Isolation (IsoFlux) and Imaging Flow Cytometry (ImageStream).

The isolation of circulating tumour cells (CTCs) in colorectal cancer (CRC) mostly relies on the expression of epithelial markers such as EpCAM, and phenotypic characterisation is usually performed under fluorescence microscopy with only one or two additional markers. This limits the ability to detect different CTC subpopulations based on multiple markers. The aim of this work was to develop a novel protocol combining two platforms (IsoFlux and ImageStream) to improve CTC evaluation.

When the routine gets complicated: Gastric and splenic perforation by a nasogastric tube.

Every invasive procedure carries some kind of risk, however rutine it may be. We present a case of a male patient which suffers a gastric and splenic perforation by a nasogastric tube, solved by means of surgery.

Hematochezia secondary to hemosuccus pancreaticus due to a pseudoaneurysm associated with a pancreatic pseudocyst.

The patient had a history of recurrent acute necrotizing pancreatitis, chronic pancreatitis and a pancreatic pseudocyst with an associated pseudoaneurysm in the superior mesenteric artery. He presented mesogastric pain, nausea, 187 U/l amylase and 242 U/l lipase. A hemorrhagic appearance inside the pseudocyst and lumen of the common bile duct was seen on ultrasound.

Precision Prevention and Cancer Interception: The New Challenges of Liquid Biopsy.

Despite major therapeutic progress, most advanced solid tumors are still incurable. Cancer interception is the active way to combat cancer onset, and development of this approach within high-risk populations seems a logical first step. Until now, strategies for the identification of high-risk subjects have been based on low-sensitivity and low-specificity assays.

Digestive involvement in a patient with Lambert-Eaton syndrome.

We present the case of a 50-year-old male diagnosed with myasthenia gravis, secondary to thymoma or Lambert-Eaton syndrome during the study of repeated vomiting. Gastrointestinal symptoms persisted despite the treatment of the thymoma. He suffered from sigma volvulus that required sigmoidectomy 9 years after diagnosis.

Enteroscopy in the diagnosis of melanoma metastases.

We present abdominal computed tomography and enteroscopy images of a 48-year-old male patient with a previous melanoma who presented with epigastric pain. The pain was not controlled with medical management. Abdominal computed tomography and a histological study of biopsies form enteroscopy confirmed the diagnosis of metastatic melanoma.

Temporomandibular joint dislocation after an upper endoscopy: a complication to consider.

After observing a case of a temporomandibular joint dislocation after an upper endoscopy, we carried out a literature review to find out how frequent it is and suggest the sedation as a possible risk factor to such complication.
