Introduction Functional constipation is a common problem in children. It usually can be managed with laxatives but a small subset of patients develop intolerable cramps and need to be temporarily treated with enemas. The senior author has previously reported: 1) open sigmoid resection as a surgical option, but this did not sufficiently reduce the laxative need, then 2) a transanal approach (with resection of rectosigmoid), but this led to a high rate of soiling due to extensive stretching of the anal canal and loss of the rectal reservoir...

BACKGROUND: The limited cell dose in umbilical cord blood (UCB) necessitates ex vivo expansion of UCB. Further, the effective cryopreservation of these expanded cells is important in widening their use in the clinics. During cryopreservation, cells experience oxidative stress due to the generation of reactive oxygen species (ROS). Conditioned medium from mesenchymal stem cells (MSCs-CM) has been shown to alleviate the oxidative stress during wound healing, Alzheimer's disease and ischemic disease...

The discovery of fossilized brains and ventral nerve cords in lower and mid-Cambrian arthropods has led to crucial insights about the evolution of their central nervous system, the segmental identity of head appendages and the early evolution of eyes and their underlying visual systems. Fundamental ground patterns of lower Cambrian arthropod brains and nervous systems correspond to the ground patterns of brains and nervous systems belonging to three of four major extant panarthropod lineages. These findings demonstrate the evolutionary stability of early neural arrangements over an immense time span...

The axonal wiring molecule Slit and its Round-About (Robo) receptors are conserved regulators of nerve cord patterning. Robo receptors also contribute to wiring brain circuits. Whether molecular mechanisms regulating these signals are modified to fit more complex brain wiring processes is unclear. We investigated the role of Slit and Robo receptors in wiring Drosophila higher-order brain circuits and identified differences in the cellular and molecular mechanisms of Robo/Slit function. First, we find that signaling by Robo receptors in the brain is regulated by the Receptor Protein Tyrosine Phosphatase RPTP69d...

Urinary tract infection (UTI) is one of the most common bacterial infections, and the incidence in women is much higher than in men. The diagnosis of a UTI can be made based on a combination of symptoms and a positive urine analysis or culture. Most UTIs are uncomplicated UTIs, defined as cystitis in a woman who is not pregnant, is not immunocompromised, has no anatomical and functional abnormalities of the urogenital tract, and does not exhibit signs of tissue invasion and systemic infection. All UTIs that are not uncomplicated are considered to be complicated UTIs...

Minimally invasive video-assisted thyroidectomy (MIVAT) has gained acceptance as an alternative to conventional thyroidectomy. This technique results in less bleeding, postoperative pain, shorter recovery time, and better cosmetic results without increasing morbidity. We retrospectively assessed outcomes in 583 patients having MIVAT from May 2005 to September 2014. The study population was divided into groups according to periods: 2005 to 2009 and 2010 to 2014. Operative data, complications, and length of stay were collected and compared...

We report a patient with a previously undiagnosed spinal dural arteriovenous fistula (SDAVF) who became acutely paraplegic following a lumbar epidural steroid injection for lumbar spinal stenosis. Magnetic resonance imaging showed multiple flow voids and serpentine vessels on the cord surface with cord edema extending from T3 through the conus. Spinal angiography confirmed an SDAVF fed by the left lateral sacral artery, which was subsequently endovascularly embolized, and the patient had a partial return of function...

The management of patients with neurogenic bladder has changed substantially over the past decades. Obtaining balanced lower urinary tract function has become possible in most patients, although, urological complications remain among the most serious complications these patients are likely to have and, even today, these can have a negative effect on quality of life. To this extent, patients with spinal cord injury (SCI) are likely to develop neurogenic bladder, and data are available on most aspects of neurogenic bladder in these patients...
