Conservative and Surgical Treatment of Osteochondromas in Children, Particularly with or without Surgical Lengthening of the Ulna.

Prevention of rotatory impairment and radial head dislocation in the forearm is an important aspect when treating children with osteochondromas. Various studies tried to determine the best treatment, describing different surgical techniques. No consensus has been reached yet. This retrospective study compares the treatment outcome of patients with osteochondroma of the radius and ulna after surgical or conservative treatment. Seventeen forearms treated over a period of 20 years were analysed. Outcome parameters were the prospectively collected clinical data and the radiological findings: "relative shortening" of ulna/radius, the "radial articular angle" (RAA) and the "carpal slip" (CS). Our study shows an improvement of the range of motion and cosmetic appearance of the forearm after an operative procedure, with or without bone lengthening. We observed an increase in wrist and elbow mobility with a decrease in pain scores and a confirmed high cosmetic satisfaction in almost 70% of the patients after bone lengthening and up to 85% after simple excision. For patients suffering from functional impairment or pain, an operative approach is beneficial. Multiple and repetitive osteochondroma excisions are recommended during growth to prevent deformity and rotatory motion restriction. Lengthening procedures require a careful indication.

Performance of axillary and rectal temperature measurement in private pediatric practice.

To better understand the role and reliability of axillary temperature measurements in clinical real life, axillary and rectal measurements in infants presenting in a private pediatric practice because of fever were compared. Prospectively, 169 infants (81 girls), median 9 (interquartile range 6-13) months of age, were examined at room temperature (20-24 °C). Two left and two right axillary, as well as two rectal measurements were taken with a digital thermometer and subsequently averaged. The median and interquartile range for axillary and rectal measurements were 36.9 (36.3-37.6) °C and 38.2 (37.4-38.9) °C, respectively (p < 0.0001). The limits of agreement in the Bland-Altman plots were 0.32 to 1.98 °C, with a mean bias of 1.15 °C. Axillary thermometers showed a good sensitivity for detecting rectal temperature > 38 °C (95%) but limited specificity (75%), with an area-under-the-curve of 0.95.Conclusions: Axillary readings are always lower than rectal ones, the limits of agreement are quite wide. Axillary readings can be used for screening but critical measurements should be confirmed by more reliable methods. What is Known • In infants and toddlers, temperature has been traditionally taken rectally. • Axillary measurements are better accepted and are recommended in current guidelines. What is New • Axillary temperature was always lower than rectal temperature. • The limits of agreement of axillary thermometers are wide. • Axillary thermometers have a good sensitivity but limited specificity and are therefore adequate for fever screening.
