Treatment of a heterotrophic ossification fracture at the proximal Achilles tendon: a case report
Pai Xu,Zhao Wang,Seung-Ho Lee,Jun-Sheng Zhang,Chan Kang 대한정형외과 스포츠의학회 2023 Arthroscopy and Orthopedic Sports Medicine Vol.10 No.2
A heterotrophic ossification fracture ~80 mm in size was found in the proximal Achilles tendon area on a plain radiograph in a 71-year-old female patient who visited the hospital due to right calf pain after jogging. On surgical findings, the entire Achilles tendon substance was changed into heterotrophic ossification in the calcaneus ossification center, and a total defect was induced after excision. Flexor hallucis longus transfer surgery, commonly used among various Achilles tendon reconstruction methods, was performed, and 14 months after the operation, satisfactory results were obtained without hindrance to daily life. Although there have been several reports of Achilles tendon ossification, no domestic report has yet been confirmed for a case in which acute fracture was prominently identified and treated when the entire proximal Achilles tendon substance was ossified.

Objective: The purposes of this study were to measure the orthodontic forces generated by thermoplastic aligners and investigate the possible influences of different activations for lingual bodily movements on orthodontic forces, and their attenuation. Methods: Thermoplastic material of 1.0-mm in thickness was used to manufacture aligners for 0.2, 0.3, 0.4, 0.5, and 0.6 mm activations for lingual bodily movements of the maxillary central incisor. The orthodontic force in the lingual direction delivered by the thermoplastic aligners was measured using a micro-stress sensor system for the invisible orthodontic technique, and was monitored for 2 weeks. Results: Orthodontic force increased with the amount of activation of the aligner in the initial measurements. The attenuation speed in the 0.6 mm group was faster than that of the other groups (p < 0.05). All aligners demonstrated rapid relaxation in the first 8 hours, which then decreased slowly and plateaued on day 4 or 5. Conclusions: The amount of activation had a substantial influence on the orthodontic force imparted by the aligners. The results suggest that the activation of lingual bodily movement of the maxillary central incisor should not exceed 0.5 mm. The initial 4 or 5 days is important with respect to orthodontic treatment incorporating an aligner.

Microbiome diversity in carriers of fluoroquinolone resistant Escherichia coli

Purpose: Fluoroquinolone-resistant (FQR) Escherichia coli causes transrectal prostate biopsy infections. In order to reduce colonization of these bacteria in carriers, we would like to understand the surrounding microbiome to determine targets for decolonization. Materials and Methods: We perform an observational study to investigate the microbiome differences in men with and without FQR organisms found on rectal culture. A rectal swab with two culturettes was performed on men before an upcoming prostate biopsy procedure as standard of care to perform “targeted prophylaxis.” Detection of FQR was performed by the standard microbiology lab inoculates the swab onto MacConkey agar containing ciprofloxacin. The extra swab was sent for 16S rRNA amplicon sequencing (MiSeq paired-end) using the V1V2 primer. Alpha and beta-diversity analysis were performed using QIIME. We used PERMANOVA to evaluate the statistical significance of beta-diversity distances within and between groups of interest. Results: We collected 116 rectal swab samples before biopsy for 16S rRNA amplicon sequencing. We identified 18 isolates (15.5%, 18/116) that were positive and had relative reduced diversity profiles (p<0.05). Enterobacteriaceae were significantly over-represented in the FQR subjects (adjusted p=0.03). Conclusions: Microbiome analysis determined that men colonized with FQR bacteria have less diverse bacterial communities (dysbiosis), higher levels of Enterobacteriaceae and reduced levels of Prevotella disiens. These results may have implications in pre/probiotic intervention studies.
