Tissue characterization using axicon probe-assisted common-path optical coherence tomography.

In this work, a common-path optical coherence tomography (OCT) system is demonstrated for characterizing the tissue in terms of some optical properties. A negative axicon structure chemically etched inside the fiber tip is employed as optical probe in the OCT. This probe generates a quality Bessel beam owning a large depth-of-field, ∼700 µm and small central spot size, ∼3 µm.

Perfusion Computed Tomography May Help in Discriminating Gastrointestinal Tuberculosis and Crohn's Disease.

Gastrointestinal tuberculosis (GITB) and Crohn's disease (CD) are close mimics. This prospective study aimed to evaluate the diagnostic performance of perfusion computed tomography (CT) in differentiating GITB from CD. Consecutive patients with ileocaecal thickening underwent perfusion CT of the ileocaecal region between January 2019 and July 2020.

Usefulness of a double immunofluorescence technique for detection of intestinal tTG-IgA deposits in diabetic and non-diabetic children with celiac disease.

Background: Celiac disease (CD) is frequently associated with type I diabetes mellitus (T1D), where its diagnosis may be a challenging task. This study aims to test the usefulness of the double staining immunofluorescence (dsIF) technique for the detection of intestinal anti-tissue transglutaminase specific IgA antibody (tTG-IgA) deposits in CD and T1D children with coexisting CD.

Methods: A total of 46 patients (30 cases of CD and 16 cases of T1D with CD) and 16 non-diabetic, non-celiac children were recruited.

Relationship of cytokines, oxidative stress and GI motility with bacterial overgrowth in ulcerative colitis patients.

Background: Ulcerative colitis (UC) is idiopathic, chronic and relapsing inflammatory bowel disease. Factors which initiate and perpetuate UC are not well understood. It is still unclear if any relationship exists between cytokines, oxidative stress, gastrointestinal (GI) motility, and small intestinal bacterial overgrowth (SIBO) in UC patients.

Cervical esophageal web and celiac disease.

Background And Aim: There is paucity of prospective data on association between cervical esophageal webs and celiac disease. It is not clear whether all patients with cervical esophageal web need screening for celiac disease. Hence, the present study was carried out to determine the association of cervical esophageal web with celiac disease.

Comparative role of antibiotic and proton pump inhibitor in experimental Clostridium difficile infection in mice.

Clostridium difficile inoculated BALB/c mice were investigated to assess the comparative role of antibiotic and proton pump inhibitor. They were examined for colonization and toxin production by C. difficile as well as myeloperoxidase activity and histopathological changes in the intestinal tract.

Oxyphilic cell adenoma of parathyroid resulting in primary hyperparathyroidism and osteitis fibrosa cystica--a case report.

Adenomas of the parathyroid gland, the majority of which are of the solitary chief cell type, are the most frequent cause of primary hyperparathyroidism (pHPT). Parathyroid adenomas composed predominantly or exclusively of oxyphil cells are rare and most oxyphil cell adenomas of this organ remain clinically silent. We present here a case of hyperfunctioning oxyphil cell adenoma of the parathyroid gland resulting in pHPT, osteitis fibrosa cystica and simultaneous bilateral fractures upper shafts of femora.
