The aim of this study was to determine the effect of ginger on intensity of nausea and vomiting after surgical procedures. This study was a randomized، double blinded، clinical trial. 160 eligible patients were randomly assigned into experimental or control groups. The experimental group received 4 capsules containing 250 mg ginger and control group received 4 placebo capsules 1 hour before surgery. The severity of nausea and vomiting was measured at 2، 4، 6 hours post operation using visual analogue scale (VAS) and a structured questionnaire. The data were analyzed by independent student t - test and Mann-Whitney U test using SPSS 16. Mean nausea score at 2 hours post operation was significantly lower in the experimental group (P= 0. 04). Mean nausea score at 4 and 6 hours post operation was lower in the experimental group; however، there was no significant difference between the groups at any time post operation. The frequencies of nausea in the experimental group at 2 and 6 hours post operation were lower than that in the placebo group، however، at 2 hours post operation، it was borderline significant (P=0. 05) There was no significant differences between two group in the intensity of nausea at any time. Use of ginger is an effective was effective at decreasing postoperative nausea. Ginger could be used as a safe antiemetic drug at post operation.

Although the overall incidence of childhood hematopoietic cancer is low, it is the most common cause of cancer in children. The aim of this paper was to ascertain the epidemiology of childhood hematopoietic and reticuloendothelial cancer according to cancer registry data system in Fars province. In this epidemiological study, the frequency distribution of blood cancer during the years 2001-2008 in children under19 years old was evaluated and occurrence rates were calculated per million per year. Data were analyzed by Excel and WinPepi 2.1. Over an 8-year period (2001-2008), 770 new cases of leukemia were recorded among 0-18 year old children including male (61.3%), 0-4 years old (26.4%) and cancer type ALL (39.4%). Moreover, most of the cases were diagnosed in 2008 (20.8%). Over this period, the ASR of leukemia in male (p<0.001), female (p<0.001) and both sexes (p<0.001) has been significantly increasing. Like other parts of the world, the trend of age-standardized incidence rate of leukemia in people under 19 in the Fars province is rising.
