Are there signs of change in gendered language use in children's early reading material?

In this study we investigate the relative frequencies of female and male terms in early reading material for children using the Children’s Printed Word Database as a resource. As roles of females and males have changed over time it is of interest to see if there has been a corresponding change in representations of females and males in children’s books. We carried out analyses regarding different words related to gender. Except for nouns referring to relatives, we found in all word groups a preponderance of male terms. The imbalance of male and female pronouns is equivalent to that reported by Carroll, Davies, and Richman (1971) in a frequency count of printed words in children’s book in the USA conducted some 40 years ago. The results are discussed in terms of gender inequality in reading materials and the development of social mores and stereotypical ideas.

The influence of different fever definitions on the rate of fever in neutropenia diagnosed in children with cancer

BACKGROUND The temperature limit defining fever (TLDF) is based on scarce evidence. This study aimed to determine the rate of fever in neutropenia (FN) episodes additionally diagnosed by lower versus standard TLDF. METHODS In a single center using a high TLDF (39.0°C tympanic temperature, LimitStandard), pediatric patients treated with chemotherapy for cancer were observed prospectively. Results of all temperature measurements and CBCs were recorded. The application of lower TLDFs (LimitLow; range, 37.5°C to 38.9°C) versus LimitStandard was simulated in silicon, resulting in three types of FN: simultaneous FN, diagnosed at both limits within 1 hour; earlier FN, diagnosed >1hour earlier at LimitLow; and additional FN, not diagnosed at LimitStandard. RESULTS In 39 patients, 8896 temperature measurements and 1873 CBCs were recorded during 289 months of chemotherapy. Virtually applying LimitStandard resulted in 34 FN diagnoses. The predefined relevantly (≥15%) increased FN rate was reached at LimitLow 38.4°C, with total 44 FN, 23 simultaneous, 11 earlier, and 10 additional (Poisson rate ratioAdditional/Standard, 0.29; 95% lower confidence bound, 0.16). Virtually applying 37.5°C as LimitLow led to earlier FN diagnosis (median, 4.5 hours; 95% CI, 1.0 to 20.8), and to 53 additional FN diagnosed. In 51 (96%) of them, spontaneous defervescence without specific therapy was observed in reality. CONCLUSION Lower TLDFs led to many additional FN diagnoses, implying overtreatment because spontaneous defervescence was observed in the vast majority. Lower TLDFs led as well to relevantly earlier diagnosis in a minority of FN episodes. The question if the high TLDF is not only efficacious but as well safe remains open.

Characteristics of Consecutive Esophageal Motility Diagnoses After a Decade of Change

BACKGROUND AND AIMS Combined multichannel intraluminal impedance and esophageal manometry (MII-EM) measures concomitantly bolus transit and pressure changes allowing determination of the functional impact of esophageal motility abnormalities. Ten years ago our laboratory reported MII-EM results in 350 consecutive patients. Since then high-resolution impedance manometry (HRIM) became available and the definitions of ineffective esophageal motility (IEM) and nutcracker esophagus were revised. The aim of this study was to assess the impact of these developments on esophageal function testing. METHODS From August 2012 through May 2013, HRIM was performed in 350 patients referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. While taking advantage of the new technology and revised criteria, HRIM findings were classified according to the conventional criteria to allow more appropriate comparison with our earlier analysis. RESULTS Compared with the study performed 10 years ago, the prevalence of normal manometry (36% vs. 35%), achalasia (7% vs. 8%), scleroderma (1% vs. 1%), hypertensive lower esophageal sphincter (LES) (7% vs. 7%), and hypotensive LES (1% vs. 2%) remained the same, whereas the prevalence of distal esophageal spasm (9% vs. 3%), nutcracker esophagus (9% vs. 3%), and poorly relaxing LES (10% vs. 3%) decreased and the prevalence of IEM increased (20% vs. 31%) significantly. Compared with the early study, normal liquid bolus transit was significantly different in patients with hypertensive LES (96% vs. 57%) and poorly relaxing LES (55% vs. 100%). CONCLUSIONS This study brings to light the increase in prevalence of IEM. In addition, it suggests that the hypertensive LES and poorly relaxing LES may each affect bolus transit in about half of these patients.
