Evaluation of the mucosal HIV reservoirs (HIV-DNA quantification and distribution of the infected T lymphocytes in the gut mucosa associated lymphoid tissue compared to the blood in HIV-1 infected patients under antiretroviral treatment with an undetectable plasma viral load below the 50 copies/ml limit of detection for at least 5 years).

The aim of this study is to investigate how bacteria and fibre interact with the epithelial cells of the gastrointestinal mucosa to reduce inflammation and to diminish tissue damage caused...
Patients undergoing elective abdominal surgery will be included prospectively. Informed consent will be obtained. Preoperatively baseline health data is collected and a skin swab and recta...
Microbicides are drugs that destroy microbes such as viruses and bacteria. Rectal microbicides may be able to prevent transmission of HIV during anal intercourse. The purpose of this study...
The purpose of this study is to discover how often certain bacteria are found in the rectum at the time of a prostate needle biopsy to diagnose prostate cancer. Certain bacteria are of imp...
Rectal and genital sampling in HIV prevention trials permits assessments at the site of HIV entry. Yet the safety and acceptability of circumcision and sigmoidoscopy (and associated abstin...
Transrectal prostate biopsies carry the risk of infection. By using non-selective culture plates, instead of commonly used ciprofloxacin (CIP)-containing plates, we analyzed the association between Es...
Since the advent of prostate-specific antigen (PSA)-based testing, transrectal ultrasound (TRUS)-guided prostate biopsy has become a standard part of the diagnostic pathway for prostate cancer (PCa). ...
Incidental, small rectal neuroendocrine tumors during colonoscopy screening are sometimes removed using biopsy forceps. Few studies have examined the clinical course of rectal neuroendocrine tumors re...
Rectal culture screening for fluoroquinolone (FQ)-resistant Enterobacteriaceae before transrectal ultrasound guided prostate (TRUSPB) biopsy and targeted antibiotic prophylaxis (TAP) may decrease post...
In patients who have undergone a colonic resection with creation of an end colostomy, drainage of mucus secreted by the mucosa of the rectal stump may not be possible if there is an outlet obstruction...
Inflammation of the COLON that is predominantly confined to the MUCOSA. Its major symptoms include DIARRHEA, rectal BLEEDING, the passage of MUCUS, and ABDOMINAL PAIN.
Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.
A form of cutaneous tuberculosis. It is seen predominantly in women and typically involves the NASAL MUCOSA; BUCCAL MUCOSA; and conjunctival mucosa.
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show infiltration of LYMPHOCYTES in the superficial EPITHELIUM and the underlying connective tissue (lamina propria).
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
