    t. Selleck MK-8245 Furthermore, valgus force produced more Wahlquist type C fractures than varus force. The present findings will help orthopedists understand the injury mechanism of the Wahlquist classification system, and will facilitate the identification of the common features of medial tibial plateau fractures induced by specific injury patterns.

    Some studies have demonstrated that the intrinsic muscles of the larynx show no signs of damage to the muscle fiber and raise a possibility of preservation of the laryngeal muscles in muscular dystrophies. A cross-sectional study was implemented with a case series of patients with Duchenne muscular dystrophy.

    This study was carried out through a medical assessment through anamnesis and medical records, perceptual-auditory evaluation of the voice in 15 patients, and videolaryngoscopic evaluation in 11 patients.

    All patients had the maximum phonation time of the vowel /e/ decreased, 7 (46.7%) had reduced loudness while 10 (66.7%) had vocal asthenia. There were no changes in muscular tone and mobility in the videolaryngoscopy.

    Patients with Duchene muscular dystrophy do not present abnormalities suggestive of the involvement of the intrinsic muscles of the larynx but have vocal worsening due to pulmonary impairment.

We describe a medically complex 6-year-old male with hyper IgM syndrome who presented with unilateral facial droop and positive SARS-CoV-2 RT-PCR. This is the first reported pediatric case of Bell’s palsy in the setting of SARS-CoV-2 infection.

    The treatment of radial longitudinal deficiency (RLD) is highly variable without clear guidelines in the literature. The current study investigated variability among hand surgeons in treatment approaches for RLD patients with anomalies of the thumb and forearm.

    An online survey was distributed to 105 self-identified North American pediatric hand surgeons and 23 international pediatric hand surgeons. The survey was developed after consideration of the controversies in RLD treatment. Variations in diagnostic approach, timing of treatment, surgical indications, and surgical techniques were presented in a 21-question survey.

    Seventy-four (57.8%) surgeons completed the survey. For type 2 hypoplastic thumb reconstruction, 81% of surgeons prefer the flexor digitorum superficialis transfer with others using the abductor digiti minimi transfer. Ninety-four percent and 100% of surgeons favored pollicization for type 3B and type 4 hypoplastic thumb, respectively. When performing pollicization, 88% of surgeons strinsus was lacking for the amount of rotation in positioning of the pollicized digit, the role of pollicization with the stiff index finger, and also in the treatment of types 2, 3, or 4 radius.

    This study provides a framework to establish treatment guidelines for thumb hypoplasia and RLD and has identified areas lacking consensus and that require additional study.

    This study examined the effect of low-profile volar rim plates (VR), proximally placed standard variable-angle locking plates (pVA-LCP), and distally placed standard variable-angle locking plates (dVA-LCP) on the flexor pollicis longus (FPL) tendon in a cadaver model. We hypothesized that tendons from the VR and pVA-LCP groups would exhibit similar contact pressures, wear patterns, and post-fatigue testing mechanical properties, whereas dVA-LCP tendons would exhibit higher contact pressures, increased tendon wear patterns, and decreased mechanical properties.

    Nine matched pairs of cadaveric specimens were used in this study. Thin-film pressure sensors were used to measure the initial contact loads between plates and FPL tendons. Specimens were cyclically loaded for 10,000 cycles by actuating the FPL tendon. Cycled tendons were harvested, photographed with a stereomicroscope, and graded for wear on a Likert scale by 5 observers who were blinded to the study protocol. Uniaxial tensile testing measured mechanical properties of the tendon ultimate failure load, ultimate stress, percent stress relaxation, elastic modulus, and stiffness.

    With regard to the cadaveric FPL tendon, VR and dVA-LCP had increased contact pressure and tendon wear compared with pVA-LCP. There were no significant differences in contact pressure or tendon wear between dVA-LCP and VR. There was no major difference in the tested mechanical properties of the FPL tendon among any of the groups.

    Plates placed directly on or beyond the volar rim demonstrate increased contact pressures and increased tendon wear in a cadaveric model.

    Although low-profile plates allow for fixation of smaller volar fragments in the distal radius, they cause substantial contact with the FPL tendon, which may rupture if the plate is not removed.

    Preoperative treatment and adequate surgery increase local control in rectal cancer. However, modalities and indications for neoadjuvant treatment may be controversial. Aim of this study was to assess the trends of preoperative treatment and outcomes in patients with rectal cancer included in the Rectal Cancer Registry of the Spanish Associations of Surgeons.

    This is a STROBE-compliant retrospective analysis of a prospective database. All patients operated on with curative intention included in the Rectal Cancer Registry were included. Analyses were performed to compare the use of neoadjuvant/adjuvant treatment in three timeframes I)2006-2009; II)2010-2013; III)2014-2017. Survival analyses were run for 3-year survival in timeframes I-II.

    Out of 14,391 patients,8871 (61.6%) received neoadjuvant treatment. Long-course chemo/radiotherapy was the most used approach (79.9%), followed by short-course radiotherapy ± chemotherapy (7.6%). The use of neoadjuvant treatment for cancer of the upper third (15-11 cm) increased over time (31.
