Femoral anteversion related to side differences in hip rotation: Passive rotation in 1, 140 children aged 8-9 years

We assessed whether the range of passive hip motion is reliable for predicting abnormal femoral ante-version. We measured the passive medial and lateral rotation in extension in both hips of 1, 140 children between 8 and 9 years of age. The children were divided into 3 groups: group 1: difference between lateral and medial rotation less than 10° group 2: medial rotation more than 10° greater than the lateral; group 3: lateral rotation more than 10° greater than the medial. Group 1 comprised 90% of the children, whereas 8% belonged to group 2 and 2% to group 3.

The angle of femoral neck anteversion was measured in 57 children from the first group, in 67 from the second and in 24 children from the third group, using biplane radiography. The mean anteversion angles in the 3 groups were 24°, 36° and 14°, respectively. To predict an abnormally high anteversion angle (above mean +2SD), the difference between medial and lateral rotation must be 45° or more, whereas an abnormally low anteversion angle (lower than mean -2SD) could be predicted when the lateral rotation was at least 50° higher than the medial rotation.     

Myoid hamartomas of the breast: report of 3 cases and review of the literature

Hamartomas were first described by Albrecht in 1904, who defined them as tumor-like malformations in which there was abnormal blending of the normal components of an organ. The myoid hamartoma is a rare benign lesion of the breast and has an uncertain origin, possibly in the walls of the blood vessels, muscularis mammillae of the areolae, and mainly in myoepithelium. We report 3 cases of myoid hamartomas of the breast, with the clinical, radiologic, and histopathological findings, and review the literature. The 3 lesions showed normal breast ducts and lobules, entrapped by a muscular stroma and some foci of mature adipose tissue. The muscular origin of part of the stroma was confirmed by strong reactiveness with smooth-muscle actin.     

War wounds to the foot

Thirty-nine patients with foot injuries were admitted to the Clinic for Orthopedic Surgery in Lovran during the war against Croatia. All of them were soldiers wounded by antipersonnel mines. All of the patients were treated using the same protocol. Primary wound care included debridement, necrectomy, and three-dimensional external fixation with or without Kirschner wires. External fixation facilitated postoperative wound care, prevented vicious contracture position, and made fracture healing possible with early weight bearing.     

Enzyme linked lectin assay (ELLA) for direct analysis of transferrin sialylation in serum samples

OBJECTIVES: Glycosylation analysis provides many opportunities for diagnostics, but its complexity hampers its routine application. Aiming to alleviate this problem, we developed a simple assay that can measure sialylation of transferrin directly from serum. DESIGN AND METHODS: Transferrin samples with different levels of sialylation were prepared by desialylation. Enzyme-linked-lectin assay (ELLA) and high-performance anion-exchange chromatography (HPAEC) have been used to analyze transferrin sialylation. Periodate oxidation was used to oxidize carbohydrates on antibodies. RESULTS: ELLA was developed for the analysis of serum transferrin sialylation. Antibodies oxidized in situ with periodate have been used to capture transferrin from serum samples. Sialic acid on transferrin has been detected with Sambucus nigra agglutinin (SNA) lectin. Transferrin samples with different sialylation levels prepared by differential desialylation have been used as standards. Accuracy of the method has been confirmed by comparison to HPAEC analysis. CONCLUSIONS: A rapid and simple ELLA that can be routinely used for the analysis of serum transferrin sialylation has been developed.     

一种镇痛泵保护装置的制作与应用

目的 探讨一种电子镇痛泵保护装置的制作与应用效果。方法 选取2019年3月-2019年9月收治于复旦大学中山医院且术后携带电子镇痛泵的患者72例,随机分成对照组（n=36）和观察组（n=36）。观察组：使用自制的保护装置固定镇痛泵,对照组：使用裸机状态直接固定的传统方式固定镇痛泵。分别对两组在镇痛泵使用中固定的稳妥性、使用安全性及医患使用体验等方面进行比较。结果 两组在使用安全性方面比较：观察组优于对照组,表现为：在泵体意外坠床例数及不明原因的停泵例数中,观察组均较对照组明显下降,有统计学意义（P ＜0.05）。医护使用自制保护装置固定镇痛泵,两组满意度比较：观察组均优于对照组,有统计学意义（P ＜0.05）。结论 应用自制电子镇痛泵保护装置在固定泵体的稳固性、安全性及使用体验方面均较传统固定方法效果更佳。
