BACKGROUND: Lateral soft-tissue release can jeopardize the common peroneal nerve (CPN) in total knee arthroplasty for valgus knees. Previous studies reporting safe zones to protect the CPN were based on well-aligned knees. We conducted this study to compare the localization of the CPN in well-aligned knees and in valgus knees. METHODS: We conducted a consecutive 3-dimensional radiographic study on magnetic resonance images of 58 well-aligned knees and 39 valgus knees...

Karan Dua, James M Barsi
Heterotopic ossification (HO) is abnormal formation of mature lamellar bone in soft tissues. HO is most commonly diagnosed in the setting of localized trauma, which results in improper differentiation of progenitor cells, leading to aberrant tissue formation. In the pediatric population, nongenetic causes of HO have rarely been reported, especially HO involving the tendons of the ankle. We present a case of HO of the peroneus brevis tendon without systemic disease in a pediatric patient. The patient was a 7-year-old female with a normal birth and developmental history who first presented 6 weeks after a right ankle sprain with pain localized to the lateral calcaneus...

Chronic expanding hematoma is characterized by continuous growth of a blood collection. We analyzed the clinical features of 7 patients with chronic expanding hematomas in the extremities, with an average age of 65.6 years. All lesions occurred in the lower extremities, with 4 seen in the thigh and 3 in the knee region. Six patients had subcutaneous hematomas, while 1 was deep-seated in the thigh. The magnetic resonance features of the lesion were compatible with those of a standard hematoma. A low signal intensity on T1- and T2-weighted imaging at the pseudocapsule was also characteristic...

Cranberry (Vaccinium macrocarpon Aiton) is used to treat non-complicated urinary tract infections (UTIs). A-type procyanidins (PAC-A) are considered the active constituents being able to inhibit bacterial adhesion to the urinary epithelium. However, there are doubts about PAC-A role in UTIs, due to their poor bioavailability, extensive metabolism, limited knowledge about urinary excretion and contradictory clinical trials. The effects of 35 days cranberry (11 mg/kg PAC-A, 4 mg/kg PAC-B) supplementation were studied in healthy rats using a UPLC-MS-based metabolomics approach...

Alzheimer's disease represents an enormous global burden in terms of human suffering and economic cost. To tackle the current lack of effective drugs and the continuous clinical trial failures might require a shift from the prevailing paradigm targeting pathogenesis to the one targeting neural stem cells (NSCs) regeneration. In this context, small molecules have come to the forefront for their potential to manipulate NSCs, provide therapeutic tools and unveil NSCs biology. Classically, these molecules have been generated either by target-based or phenotypic approaches...

Hepatitis E virus (HEV) has been detected in rabbits, but whether rabbit HEV strains can be transmitted to humans is not known. Of 919 HEV-infected patients in France during 2015-2016, five were infected with a rabbit HEV strain. None of the patients had direct contact with rabbits, suggesting foodborne or waterborne infections.

Executive function (EF) plays a foundational role in development. A brain-based model of EF development is probed for the experiences that strengthen EF in the dimensional change card sort task in which children sort cards by one rule and then are asked to switch to another. Three-year-olds perseverate on the first rule, failing the task, whereas 4-year-olds pass. Three predictions of the model are tested to help 3-year-olds (N = 54) pass. Experiment 1 shows that experience with shapes and the label "shape" helps children...

Peroneal tendon pathology is an important cause of lateral ankle pain and instability. Typical peroneal tendon disorders include tendinitis, tenosynovitis, partial and full thickness tendon tears, peroneal retinacular injuries, and tendon subluxations and dislocations. Surgery is usually indicated when conservative treatment fails. Familiarity with the peroneal tendon surgeries and expected postoperative imaging findings is essential for accurate assessment and to avoid diagnostic pitfalls. Cross-sectional imaging, especially ultrasound and MRI provide accurate pre-operative and post-operative evaluation of the peroneal tendon pathology...

BACKGROUND: Recently, significant progress in both safety and efficacy has been achieved in the field of xenotransplantation, as exemplified by results from the first clinical trials of porcine islet transplantation. It would be of interest to learn whether the attitude of the clinical staff involved in such trials changes as the trials are carried out in their own hospital. METHODS: One hundred and four clinical staff members from the Eva Peron Hospital of San Martin (Buenos Aires, Argentina) where clinical trials of islet xenotransplantation have been performed and 92 similar staff members from the Diego Thompson Hospital (Buenos Aires, Argentina) where no such xenotransplantation has been carried out participated in the study...

INTRODUCTION: Excitability properties of motor nerves to different muscles are different, but the explanation is uncertain. We characterized motor axon excitability properties to the medial gastrocnemius (MG) in 27 adults, and made comparisons with the peroneal nerve to the tibialis anterior (TA) and median nerve to the abductor pollicis brevis (APB) in 10 subjects. METHODS: Recordings of multiple excitability properties were made using threshold tracking, stimulating the nerves at the wrist or knee...
