Comparing the Tibial Tuberosity-Trochlear Groove Distance Between CT and MRI in Skeletally Immature Patients With and Without Patellar Instability.

Background: The tibial tubercle-trochlear groove (TT-TG) distance was originally described for computed tomography (CT), but it has been measured on magnetic resonance imaging (MRI) in patients with patellar instability (PI). Whether the TT-TG measured on CT versus MRI can be considered equivalent in skeletally immature children remains unclear.

Purpose: To investigate in skeletally immature patients (1) the effects of CT versus MRI imaging modality and cartilage versus bony landmarks on consistency of TT-TG measurement, (2) the difference between CT and MRI measurements of the TT-TG, and (3) the difference in TT-TG between patients with and without PI.

Temporary hemiepiphysiodesis using an eight-plate implant for coronal angular deformity around the knee in children aged less than 10 years: efficacy, complications, occurrence of rebound and risk factors.

Background: Temporary hemiepiphysiodesis (TH) using an eight-Plate implant is one of the most common surgeries used for the correction of coronal angular deformities around the knee in adolescents. However, few studies have focused on children aged less than 10 years treated with TH using an eight-Plate implant. The purpose of this study was to investigate the efficacy, correction velocity, and complications of TH with an eight-Plate implant as well as the occurrence of rebound and risk factors in this population.

Risk factors for implant-related fractures after proximal femoral osteotomy in children with developmental dysplasia of the hip: a case-control study.

Background and purpose - Proximal femoral osteotomy (PFO) is commonly performed to treat children with developmental dysplasia of the hip (DDH). Implant-related femoral fractures after osteotomy are sometimes reported, but the potential risk factors for these fractures remain unclear. We investigated the association of implant-related fractures with PFO and potential risk factors for these fractures.

Analysis of risk factors for complications after femoral neck fracture in pediatric patients.

Background: Pediatric femoral neck fracture is a rare injury but yields frequent complications. However, there is a paucity of data regarding the risk factors for these complications.

Purpose: The present article reports the rate of complications after femoral neck fracture in pediatric patients and investigates the possible risk factors.

Postnatal delayed growth impacts cognition but rescues programmed impaired pulmonary vascular development in an IUGR rat model.

Background And Aims: Intrauterine growth restriction (IUGR) is a state of slower fetal growth usually followed by a catch-up growth. Postnatal catch-up growth in IUGR models increases the incidence of pulmonary arterial hypertension in adulthood. Here, we hypothesize that the adverse pulmonary vascular consequences of IUGR may be improved by slowing down postnatal growth velocity.

Echocardiographic evaluation of cardiac dyssynchrony in patients with congestive heart failure.

The present study investigated the application of echocardiography to evaluation of cardiac dyssynchrony in patients with congestive heart failure (CHF). A total of 348 consecutive CHF patients who were admitted for cardiac resynchronization (CRT) and presented with low ejection fraction (EF) and wide QRS duration were enrolled in this study, along with 388 healthy individuals. Dyssynchrony was assessed based on filling time ratio (FT/RR), left ventricular pre-ejection delay (PED), interventricular mechanical delay (IVMD), longitudinal opposing wall delay (LOWD) and radial septal to posterior wall delay (RSPWD).

Leptin induces the apoptosis of chondrocytes in an in vitro model of osteoarthritis via the JAK2‑STAT3 signaling pathway.

Emerging data has suggested a high prevalence of osteoarthritis (OA) among obese people. As an important adipokine secreted by white adipose tissue, leptin may be a key mediator in the progression of OA. Leptin exerts a catabolic effect on OA cartilage by increasing the production of metalloproteinase (MMP) enzymes, and contributes to apoptosis in chondrocytes.

[Study on the relationship between structure and spectroscopy of two compounds containing 2,2'-bipy and [MoO3] cluster skeletons].

Two compounds of molybdate with 2, 2'-bipy and [MoO3]: [(2, 2'-bipy)2 (MoO3)3]n (I) and [(2, 2'-bipy) (MoO3)]n (II) were successfully synthesized by hydrothermal synthesis method with programmable temperature control. In order to clarify the relationship between the structure and spectroscopy of these two compounds, both of them were characterized by means of X-ray powder diffraction (XRD), Fourier transform infrared spectra(FTIR), thermal perturbation 2D-IR correlation spectrum (2D-IR COS), thermogravimetric analysis(TGA), scanning electron microscopy(SEM), High temperature infrared analysis, UV-Vis DRS adsorption spectra and solid fluorescence spectrum to investigate the relationship between structure and properties of the title compounds. The powder XRD patterns of the complexes are well matched with the simulation based on single-crystal analysis, which indicate that compound I and II are in a pure phase.

Posterior interosseous nerve entrapment after Monteggia fracture-dislocation in children.

Objective: Although most of nerve injuries associated with Monteggia fracture-dislocation in children are neurapraxias and will recover spontaneously after conservative treatment, surgical exploration of the involved nerve is always required in the cases with the entrapment of posterior interosseous nerve (PIN). However, the necessity and time frame for surgical intervention for specific patterns of nerve dysfunction remains controversial. The aim of the report is to observe and understand the pathology of PIN injury associated with Monteggia fracture-dislocation in children, and to propose the possible indication for the exploration of nerve.
