Estimation of the Prevalence of Inadequate and Excessive Iodine Intakes in School-Age Children from the Adjusted Distribution of Urinary Iodine Concentrations from Population Surveys.

Background: The urinary iodine concentration (UIC), a biomarker of iodine intake, is used to assess population iodine status by deriving the median UIC, but this does not quantify the percentage of individuals with habitually deficient or excess iodine intakes. Individuals with a UIC <100 μg/L or ≥300 μg/L are often incorrectly classified as having deficient or excess intakes, but this likely overestimates the true prevalence.

Objective: Our aim was to estimate the prevalence of inadequate and excess iodine intake in children (aged 4-14 y) with the distribution of spot UIC from iodine surveys.

Neoadjuvant chemotherapy plus conventional radiotherapy or accelerated hyperfractionation in stage III and IV nasopharyngeal carcinoma--a phase II study.

A prospective phase II trial was initiated in previously untreated patients with locally advanced nasopharyngeal carcinoma (NPC). The goal was to achieve improvement in locoregional control, disease-free interval and overall survival using induction chemotherapy and to compare conventional fractionation (CF) with an accelerated hyperfractionation (AHF) regimen. Fifty patients were treated (5 AJCC Stage III, 45 Stage IV) with induction chemotherapy consisting of two cycles of cisplatin and 5-fluorouracil.

Reduced expression of mismatch repair genes in colorectal cancer patients in Egypt.

An Egyptian hospital-based pilot case-control study was conducted to investigate the relationship between the expression level of mismatch repair (MMR) genes and the risk of colorectal cancer. The relative expression of five known MMR genes, i.e.
