The embryonic origin of the urogenital system came from the intermediate mesoderm. Kidney development involves three successive renal systems with a fast chronological overlap: the pronephro, the mesonephro, and the metanephro. Due to the lack of specific knowledge about this system in cats the present work aimed to describe their urinary organs development, focusing on the structures seen in pronephro, mesonephro, and metanephro during the embryonic and fetal stages of development. The techniques used in this study were: light microscopy, immunohistochemistry, scanning electron microscopy, and transmission electron microscopy...

The skin/implant interface of osseointegrated (OI) implants is susceptible to infection, causing excess pain, increased morbidity, and possibly implant removal. Novel distal femoral OI implants with binary nitride coatings have been developed with little physiological modeling to collect microbiological evidence of resistance to bacterial attachment. This in vitro study evaluated a Ti-6Al-4V alloy coated with TiNbN and treated with low plasticity burnishing (LPB) to assess attachment and biofilm formation of methicillin-resistant Staphylococcus aureus (MRSA) under physiologically-modeling conditions compared to standard Ti-6Al-4V alloy materials with a polished ("Color Buff") or non-polished finish ("Satin Finish")...

A 62-year-old man was referred to our institution for high-density, symptomatic PVCs with resultant decrease in LV function having failed prior ablation attempts. Successful, durable ablation of the patient's mid-myocardial PVC arising from the LV summit region was achieved through the proximal great cardiac vein with ablation depth augmented by use of half-normal saline irrigant. Though standard ablation of ventricular arrhythmias using normal saline irrigation from the coronary venous system has been well-reported, this may be of limited value in addressing mid-myocardial sites of origin...

INTRODUCTION: Distal radius fractures (DRF) are the most common fractures of the upper extremities. The incidence is expected to continue rising in the next years due to the increased life expectancy. Palmar locking plate stabilizing has since become the standard treatment for dorsally displaced DRF with a complication rate of 8-39% reported in the literature. Main aim of this study was to investigate the incidence of complications after DRF stabilization using palmar angular stable locking plate...

OBJECTIVES: Off-pump coronary artery bypass grafting (OPCAB) may have advantages in the elderly. Although proven safe, it remains unclear whether OPCAB provides a short-term survival benefit in octogenarians. We sought to compare outcomes using propensity matching between OPCAB and conventional surgery in a statewide database. METHODS: We identified all octogenarians (≥ 80 years) who underwent isolated coronary artery bypass grafting (CAB) at 10 different centers in the state of Maryland from July 2011 to June 2016...

Myotonic dystrophy is an autosomal dominant muscular dystrophy not only associated with muscle weakness, atrophy, and myotonia but also prominent multisystem involvement. There are 2 similar, but distinct, forms of myotonic dystrophy; type 1 is caused by a CTG repeat expansion in the DMPK gene, and type 2 is caused by a CCTG repeat expansion in the CNBP gene. Type 1 is associated with distal limb, neck flexor, and bulbar weakness and results in different phenotypic subtypes with variable onset from congenital to very late-onset as well as variable signs and symptoms...

The control and the execution of motor tasks are largely influenced by proprioceptive feedback, i.e. the information about the position and movement of the body. In 1972, it was discovered that a vibratory stimulation applied non-invasively to a muscle or a tendon induces a movement illusion consistent with the elongation of the vibrated muscle/tendon. Although this phenomenon was reported by several studies, it is still unclear how to reliably reproduce it because of the many different features of the stimulation altering the sensation (e...

BACKGROUND: The interaction of the gut microbiota with the human host is implicated in the pathogenesis of inflammatory and immunological diseases including ulcerative colitis (UC). Faecal microbiota transplantation (FMT) as a method of restoring gut microbial diversity is of increasing interest as a therapeutic approach in the management of UC. The current literature lacks consensus about the dose of FMT, route of administration and duration of response. METHODS AND ANALYSIS: This single-blinded randomised trial will explore the feasibility of FMT in 30 treatment-naïve patients with histologically confirmed distal UC limited to the recto-sigmoid region (up to 40 cm from the anal verge)...

The various surgical techniques to treat iliotibial band friction syndrome consist in releasing the iliotibial band by means of plasties that partially interrupt its continuity or by release of the deep aspect. We describe an original technique of digastric distal iliotibial band release from Gerdy's tubercle. Via a 2 cm approach above Gerdy's tubercle, the iliotibial band is incised longitudinally and partially released from the tubercle. Fourteen knees underwent the procedure. With a mean 27±20.6 months' follow-up (range, 12-69 months), return to sport at previous level was possible at a mean 4±2...

BACKGROUND: Vulvodynia, or vulvar pain, is a common condition in women; however, there are few evidence-based clinical trials evaluating nonpharmacological therapies for this condition. Acupuncture is one complementary and integrative medicine therapy used by some patients with vulvodynia. This study evaluates two different acupuncture strategies for the treatment of vulvodynia and aims to evaluate whether either of the acupuncture protocols reduces vulvar pain, pain duration or pain with intercourse...

BACKGROUND: Restoring the normal joint line (JL) is an important goal to achieve in total knee arthroplasty (TKA). We intended to study the veracity of several landmarks used to level the normal JL in Chinese people. METHODS: Two hundred fifteen standard CT scans of knee joint were included to measure the distances from landmarks to distal JL (DJL) and posterior JL (PJL), along with femoral width (FW) in order to calculate the ratios. Landmarks included adductor tubercle (AT), medial epicondyle (ME), lateral epicondyle (LE), tibial tubercle (TT), fibular head (FH) and the inferior pole of the patella (IPP)...

BACKGROUND: Surgery for adult spinal deformity requires optimal patient-specific spino-pelvic-lower extremity alignment. Distal fixation in thoracolumbar spinal deformity surgery is crucial when arthrodesis to the sacrum is indicated. Although we had performed sacro-pelvic fixation with bilateral S1 and bilateral single iliac screws previously, iliac screw loosening and/or S1 screw loosening occurred frequently. So, the authors attempted to fuse spino-pelvic lesions with the dual iliac screws and S1 pedicle screws...

BACKGROUND: Proximal brachial plexus blocks can lead to an extended period of motor paralysis and delay the return of motor function. This could influence patient satisfaction, and extend hospitalizations. The aim of the study is to compare a selective distal nerve block of the arm to a proximal axillary block, both ultrasound-guided, in terms of their motor block intensity of the elbow. Our hypothesis is that a selective nerve block of the arm would result in a different motor block of the elbow, compared to the axillary block...
