Does Family History of Cancer Influence Undergoing Screening and Gastrointestinal Investigations?
2020
Background and Aims: Although a family history of cancer (FHC) can modify the lifestyle and attitudes towards participation in cancer screening programs, studies on this relationship show mixed results and vary across populations. The objectives of the study were to compare sociodemographic characteristics, history of gastrointestinal (GI) investigations and Helicobacter pylori eradication, and modifiable cancer risk factors between those with FHC and those with no FHC (NFHC), and to investigate the association between FHC and a history of GI investigations.
 Methods: A total of 3,455 questionnaires from the pilot study of the “Helicobacter pylori eradication and pepsinogen testing for…
Immunochemical faecal occult blood tests for colorectal cancer screening: No time to lose
2013
Letter by Wachter et al regarding article, "occult atrial fibrillation in cryptogenic stroke: detection by 7-day electrocardiogram versus implantable…
2013
To the Editor: We read with great interest the article of Ritter et al,1 which nicely demonstrates that the prolongation of ECG monitoring time increases the detection rate of paroxysmal atrial fibrillation in stroke patients, a result that is in concordance with existing literature. One aspect especially drawn to our attention was the lower yield of the Holter monitoring during simultaneous ECG recording as compared with the implantable loop recorder (ILR). ILRs only store automatically triggered episodes and can detect only atrial fibrillation (AF) episodes of ≥2 minutes, whereas Holter ECGs store (usually semiautomatically analyzed) continuous recordings and …
Diagnostic accuracy of computed tomographic colonography for the detection of advanced neoplasia in individuals at increased risk of colorectal cance…
2009
CONTEXT: Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE: To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter, cross-sectional study. Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positiv…

Occult non-metallic intraocular foreign body causing recurrent anterior uveitis
2015
Purpose To describe the case of textile worker with recurrent anterior uveitis following the traumatic penetration of nylon thread into the anterior segment of the eye. Methods Examination by slit-lamp of the affected eye B-scan ultrasonography during the inflammatory episode and after the resolution of the uveitis. Visual Acuity Measurement during the inflammatory episode and after the resolution of the uveitis. Results The use of topical therapy together with antibiotic systemic therapy led to the regression of the inflammatory symptoms (intense epibulbar and tarsal hyperemia with perikeratic reaction, corneal sub-oedema with some folds in the Descemet's membrane, Tyndall 2+ and a layer o…
Science to Practice: Should Biopsy Be Performed in Potential Liver Donors When Unenhanced CT Shows an Unacceptable Degree of Steatosis for Transplant…
2006
Park et al (1) have demonstrated that unenhanced CT can accurately depict moderate to severe (ie, ≥30%) macrovesicular steatosis, thereby allowing avoidance of biopsy in potential living liver donors who have an unacceptable degree of steatosis for transplantation. Biopsy will still be needed in donors with macrovesicular steatosis of less than 30% at unenhanced CT to rule out occult chronic liver disease and more severe steatosis that is undetected at CT. © RSNA, 2006.
Improving uptake of screening for colorectal cancer: a study on invitation strategies and different test kit use
2015
Objective The aim of this study was to compare the uptake of mail-delivered tests for colorectal cancer screening. We assessed the effect of an advance notification letter and a reminder letter, and analysed the proportion of inappropriately handled tests. Materials and methods Fifteen thousand randomly selected residents of Latvia aged 50–74 years were allocated to receive one of three different test systems: either a guaiac faecal occult blood test (gFOBT) or one of two laboratory-based immunochemical tests (FIT) – FOB Gold or OC-Sensor. Half of the target population received an advance notification letter; all nonresponders were sent a reminder letter. Results The uptake of screening was…
Programmed colorectal cancer screening decreases incidence and mortality
2019
Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer- related deaths in the world (1). Detecting and removing precancerous lesions or detecting tumors in early stages through endoscopy decreases CRC mortality (2). Randomized controlled trials (RCTs) have shown that CRC screening based on guaiac fecal occult blood testing (gFOBT) and flexible sigmoidoscopy is effective in reducing incidence and mortality rates of CRC (3).
GASTRIC METASTASES ORIGINATING FROM OCCULT BREAST LOBULAR CARCINOMA: DIAGNOSTIC AND THERAPEUTIC PROBLEMS
2008
Abstract Background Breast cancer is the most frequent malignant tumour to metastasize into the gastrointestinal tract in female and is second only to malignant melanoma. Nevertheless gastrointestinal metastases arising from breast cancer are quite rare. The upper gastrointestinal tract is more frequently involved and lobular infiltrating carcinoma has a greater predilection compared to the ductal type. Case presentation The authors describe the case of a 70 years old woman with a preoperative diagnosis of gastric undifferentiated medullary – type carcinoma, which was the first manifestation of an occult breast carcinoma. The primary site of carcinoma was identified with the use of a panel …
