  • estimation of effective dose from dose area product measurements for Barium Meals and Barium enemas
    British Journal of Radiology, 1994
    Co-Authors: F Wall
    Abstract:

    Abstract The International Commission on Radiological Protection has recommended the use of a new dose quantity “effective dose”. The doses to 22 organs of the human body are required for a formal calculation of this quantity. This paper shows that a quick estimate of the effective dose received by a patient from a Barium Meal or a Barium enema can be made by multiplying the measured dose–area product for the complete examination by an appropriate conversion coefficient. Despite the varied techniques used for Barium examinations, such an estimate is unlikely to be in error by more than 25%.

  • monte carlo estimation of radiation doses during paediatric Barium Meal and cystourethrography examinations
    Physics in Medicine and Biology, 2011
    Co-Authors: A Dimitriadis, G Gialousis, Triantafillia Makri, M Karlatira, P Karaiskos, E Georgiou, S Papaodysseas, E Yakoumakis
    Abstract:

    Organ doses are important quantities in assessing the radiation risk. In the case of children, estimation of this risk is of particular concern due to their significant radiosensitivity and the greater health detriment. The purpose of this study is to estimate the organ doses to paediatric patients undergoing Barium Meal and micturating cystourethrography examinations by clinical measurements and Monte Carlo simulation. In clinical measurements, dose–area products (DAPs) were assessed during examination of 50 patients undergoing Barium Meal and 90 patients undergoing cystourethrography examinations, separated equally within three age categories: namely newborn, 1 year and 5 years old. Monte Carlo simulation of photon transport in male and female mathematical phantoms was applied using the MCNP5 code in order to estimate the equivalent organ doses. Regarding the micturating cystourethrography examinations, the organs receiving considerable amounts of radiation doses were the urinary bladder (1.87, 2.43 and 4.7 mSv, the first, second and third value in the parentheses corresponds to neonatal, 1 year old and 5 year old patients, respectively), the large intestines (1.54, 1.8, 3.1 mSv), the small intestines (1.34, 1.56, 2.78 mSv), the stomach (1.46, 1.02, 2.01 mSv) and the gall bladder (1.46, 1.66, 2.18 mSv), depending upon the age of the child. Organs receiving considerable amounts of radiation during Barium Meal examinations were the stomach (9.81, 9.92, 11.5 mSv), the gall bladder (3.05, 5.74, 7.15 mSv), the rib bones (9.82, 10.1, 11.1 mSv) and the pancreas (5.8, 5.93, 6.65 mSv), depending upon the age of the child. DAPs to organ/effective doses conversion factors were derived for each age and examination in order to be compared with other studies.

  • Endoscopic fibrin sealing of congenital pyriform sinus fistula.
    Surgical endoscopy, 2004
    Co-Authors: B. Cigliano, L. Cipolletta, N. Baltogiannis, Ciro Esposito, Alessandro Settimi
    Abstract:

    Pyriform sinus fistula is a very rare branchial apparatus malformation, often appearing in the form of a cervical inflammatory process (abscess or suppurative thyroiditis), especially in infants. Failure to diagnose this lesion may result in unexpected recurrence. A case of recurrent suppurative thyroiditis caused by pyriform sinus fistula in a 9-year-old girl is reported. In the latency period of infection, the fistula tract was identified by a Barium Meal contrast study. Direct endoscopy showed the fistula internal orifice at the apex of the left pyriform fossa. The fistula was completely obliterated by injection of fibrin glue. Suppurative thyroiditis is reported mainly in the pediatric literature, and the reported case is the first to be managed endoscopically by injection of fibrin adhesive.

  • oral peppermint oil is a useful antispasmodic for double contrast Barium Meal examination
    Journal of Gastroenterology and Hepatology, 2006
    Co-Authors: Shigeaki Mizuno, Kimitoshi Kato, Yoshiki Ono, Kiyoshi Yano, Hanzo Kurosaka, Atsuhiko Takahashi, Hiromi Abeta, Toshio Kushiro, Syunpachi Miyamoto, Ryuichi Kurihara
    Abstract:

    BACKGROUND AND AIM: Intraluminally administered peppermint oil (PO) is reportedly a safe and useful antispasmodic for gastroscopy, colonoscopy and double-contrast Barium enema. The aim of this study was to examine the efficacy of oral PO for double-contrast Barium Meal examination (DCBM) without other antispasmodics. METHODS: Two hundred and five randomly chosen subjects (PO group) and 215 sex- and age-matched controls were enrolled. All participants underwent DCBM. The PO group was orally administered PO and a Barium suspension mixture at the start of DCBM. Radiographs were blindly evaluated for spasm and overlapping with Barium-filled duodenal loops (scored 0-3, indicating none to severe). The quality of Barium coating of the mucosa and overall diagnostic quality (scored 0-3, indicating not acceptable to excellent) were also evaluated. RESULTS: There was no significant difference in subject acceptance between PO group and controls, and no adverse effects in either group. Scores for spasm at the esophagus, lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.001). Scores for overlapping at the lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.05, P < 0.01, respectively). Scores for overall diagnostic quality at the esophagus, lower stomach and duodenal bulb were significantly higher in the PO than in the control group (P < 0.001). Oral PO reduces spasm of the esophagus, lower stomach and duodenal bulb, inhibits Barium flow to the distal duodenum, and improves diagnostic quality without other antispasmodics. CONCLUSIONS: Oral PO is a safe, easy to use and effective antispasmodic for DCBM.
