BACKGROUND: Osteoporosis is a disease of bones that leads to an increased risk of fracture. Epimedii Folium is commonly used for treating bone fractures and joint diseases for thousands of years in China. METHODS: This study was aimed to screen active components, which might have the potency to stimulate osteoblasts proliferation and differentiation in Epimedii Folium. An HPLC method was established to analyze the main components in Epimedii Folium. The MTT and ALP methods were utilized for the assay of osteoblasts proliferation and differentiation activity...

This article reports the use of elastic suture as an adjuvant in surgical wound closure caused by decompressive fasciotomy after compartment syndrome associated with a compound fracture of the tibia. Widely used in other medico-surgical specialties, this technique is unusual in orthopedics surgery, but the simplicity of the procedure and the successful outcome observed in this case allows for its consideration as indicated for situations similar to that presented in this study.

We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI) was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by two Kirschner wires was performed, the trapezoid fracture was conservatively treated. Surgery was followed by immobilization, intense physiotherapy and close follow-up...

Although pesticides are primarily degraded in the topsoil, significant attenuation can be expected in groundwater systems where the transit time of pesticides usually are orders of magnitude longer than in the soil. Because degradation and transport processes in the subsurface take place at time scales of months to years or even decades, direct measurements of natural attenuation are hampered by practical and logistical limitations (for instance the limited duration of sampling or a correct estimation of the pesticide flux into groundwater)...

Hydraulic fracturing is an industrial process allowing for the extraction of gas or oil. To fracture the rocks, a proprietary mix of chemicals is injected under high pressure, which later returns to the surface as flowback and produced water (FPW). FPW is a complex chemical mixture consisting of trace metals, organic compounds, and often, high levels of salts. FPW toxicity to the model freshwater crustacean, Daphnia magna, was characterized utilizing acute (48 h median lethal concentrations; LC50) and chronic (21 d) exposures...

BACKGROUND: Severe compound tibial fractures are associated with extensive soft-tissue damage, resulting in disruption of lymphatic pathways that leave the patient at risk of developing chronic lymphedema. There are limited data on lymphatic response following lower limb trauma. Indocyanine green fluorescence lymphography is a novel, real-time imaging technique for superficial lymphatic mapping. The authors used this technique to image the superficial lymphatic vessels of the lower limbs in patients with severe compound tibial fracture...

BACKGROUND: Osteogenesis imperfecta (OI) is a heterogeneous bone disorder characterized by recurrent fractures. Although most cases of OI have heterozygous mutations in COL1A1 or COL1A2 and show autosomal dominant inheritance, during the last years there has been an explosion in the number of genes responsible for both recessive and dominant forms of this condition. Herein, we have analyzed a cohort of patients with OI, all offspring of unaffected parents, to determine the spectrum of variants accounting for these cases...

ABSTRACT: Atypical subtrochanteric and diaphyseal femoral fractures (AFF) have been suggested to be associated with the use of bisphosphonates (BPs), but the role of these drugs is still under debate. A 64-year old female, never treated with BPs was admitted to our Rehabilitation Institute because of a recent right AFF. The patient began suffering from low back pain radiating to the groin and to the anterior regions of the right thigh and leg, A nuclear magnetic resonance (NMR) of the lumbar spine showed disc protrusions at the L3-L4 and L5-S1 levels with impingement of the spinal nerve root...

Fibromuscular dysplasia (FMD) is a rare, segmental, nonatheromatous, and noninflammatory arterial disease of unknown etiology. It predominantly involves renal artery (60-75%) followed by extracranial part of the internal carotid artery and vertebral arteries (25-30%). The disease typically affects middle-aged women and involves intermediate-sized arteries throughout the body. There are rare case reports of extracranial FMD compounding a trauma case. A patient was brought to trauma center emergency with a history of fall from height...
