Abstract
Adult stromal mesenchymal stem cells (MSCs) have been postulated as responsible for cell renewal in highly and continuously regenerative tissues such as the endometrium. MSCs have been identified in the endometrium of many species including humans, rodents, pets and some farm animals, but not in horses. The objective of this work was to isolate such cells from the endometrium of mares and to compare their main biological attributes with horse adipose-derived MSCs. Here we successfully isolated and characterized endometrial MSCs (eMSCs) from mares. Said cells showed fibroblast-like morphology, grew on plastic, had doubling population times of 46.4 ± 3.38 h, underwent tri-lineage (osteo, chondro and adipogenic) differentiation after appropriate inductions, migrated toward the attraction of fetal calf serum and displayed a pattern of surface markers commonly accepted for horse MSCs. All these are properties of MSCs. Some of these attributes were shared with equine adipose-derived MSCs, but the migration pattern of eMSC at 12 and 24 h after stimulation was reduced in comparison with adipose MSCs. Also, expression of CD44, CD90 and MHCI surface markers were dramatically down-regulated in eMSCs. In conclusion, equine-derived endometrial MSC share biological attributes with adipose MSC of this species, but displayed a different surface marker phenotype and an impaired migration ability. Conceivably, this phenotype is distinctive for MSC of this origin.

Abstract
OBJECTIVES We present our case studies on paediatric urolithiasis, the techniques employed in its treatment and its results. MATERIAL AND METHODS A retrospective study of paediatric urolithiasis of the upper urinary tract (UUT) treated at our centre between 2003 and 2014. We recorded demographic, clinical, diagnostic and therapeutic data and the complications. The therapeutic plan was recorded as isolated (extracorporeal lithotripsy, ureterorenoscopy, nephrolithotomy or surgery) or combined therapy. RESULTS We examined 41 renal/urethral units in 32 patients. The median age was 5 years (range, 11 months-14 years). The mean size was 12.9cm (±7.3mm). The locations were as follows: 23 (56%) in the renal pelvis (staghorn in 15 cases), 10 (24) in lower calyx and 8 (20%) in the urethra. We performed 80 procedures, with no differences in the age groups, which resulted in 12 complications (15%) but no septic condition secondary to lithotripsy. Stone removal from the urethra had a 100% success rate with the ureterorenoscopy. The overall cure rate was 90%. CONCLUSION The paediatric urolithiasis approach offers multiple alternatives. It is therefore important to tailor the procedure according to the size, location and composition of the stone. In our centre, the use of paediatric extracorporeal shock wave lithotripsy is safer. Ureterorenoscopy, semirigid or flexible, provides excellent results in ureters. Percutaneous nephrolithotomy with minimal access can be performed on small children and nursing infants.

Abstract
CLINICAL PROBLEM We diagnosed 8 patients with late-stage posterior urethral valves (PUV) between 1 and 14 years of age. Five patients complained of symptoms related to voiding dysfunction. The other 3 patients required urethrocystoscopy for other reasons (hypospadias fistulae, difficulty with catheterisation and high-grade vesicoureteral reflux [VUR]). A second review of the first 2 patients' medical history showed voiding dysfunction symptoms. All patients underwent preoperative ultrasonography: 3 patients had normal results and 5 had renal or vesical disorders. The diagnosis was reached through voiding cystourethrogram (VCUG), and 4 patients underwent urodynamic studies. The diagnosis was confirmed by urethrocystoscopy, performing valve electrofulguration. We performed urethrocystoscopy during the check-ups at 3-6 weeks and observed no stenosis. The symptoms disappeared for all patients after 20 months of follow-up. The patient with VUR was cured. The ultrasounds showed no progression of the renal involvement and showed improvement in the vesical involvement. The velocimetries during check-ups presented curves within normal ranges. DISCUSSION Most children with PUV are diagnosed through ultrasound during the neonatal period. Some patients present PUV at later ages with diverse symptoms, which impedes its diagnosis. We should suspect PUV in male patients with symptoms of voiding dysfunction, either when they have normal or pathological results from ultrasounds or VCUG. We recommend performing urethrocystoscopy to rule out urethral obstruction.

Abstract
BACKGROUND/AIM Neither cervicotomy nor postero-lateral thoracotomy allow safe surgical access to the lower cervical spine and high posterior mediastinum with full control of the vascular and neural structures involved. We report our favorable experience with cervico-sternotomy for accessing this region. PATIENTS AND METHODS Six patients were operated upon between 1998 and 2011 for either removal of huge cervico-thoracic neural ganglioneuromas (n = 2) or anterior arthrodesis for congenital (n = 2), neuropathic (n = 1) or osteolytic scoliosis (n = 1). In all cases, cervicotomy was followed by sternotomy, thymectomy, division of the innominate vein and dissection of jugular veins, carotid arteries and vagus nerves. RESULTS The tumors measured 10.9 x 3.9 x 8.7 cm and 8 x 6 x 5 cm, and involved the paravertebral chain from the aortic arch to the base of the skull and from the left lung hilus to the thyroid region respectively. In the scoliosis patients, anterior vertebral fixation between C5 and T5 was readily feasible. Blood transfusion was avoided. Horner's syndrome and transient lymphedema were the only complications. Median operative time was 210 minutes (range 180-240 minutes) and median estimated blood loss was 2.7 cc/kg (0-13.8 cc/kg). Median hospital stay was 7 days (range 5-18 days). CONCLUSIONS Cervico-sternotomy is an optimal approach for this anatomical region in children. It offers better exposure of the anterior cervico-thoracic spine and the thoracic inlet than cervicotomy or thoracotomy. Control of the nervous and vascular structures was safely achieved in all cases and postoperative discomfort was surprisingly limited.

Abstract
BACKGROUND Pill burden, dosing frequency, and concerns about safety and tolerability are important obstacles to maintaining adequate medication adherence. Raltegravir (RAL) is indicated for twice-daily dosing and when taken with emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF), it becomes a twice-daily multiple-tablet regimen. Elvitegravir (EVG)/cobicistat (COBI)/FTC/TDF, STB, is the first approved once-a-day integrase strand transfer inhibitor (INSTI) containing single-tablet regimen that combines EVG, an INSTI, and COBI, a novel pharmacoenhancer, with the preferred nucleos(t)ide backbone of FTC/TDF. METHODS This was a 48-week prospective, single-arm open-label study of the switch to STB in virologically sup-pressed HIV-1-infected adult patients on FTC/TDF and twice-daily RAL for at least 6 months. Objectives were to evaluate the tolerability and safety of a regimen simplification to once-a-day STB, while maintaining viral suppression through 48 weeks. RESULTS Forty-eight individuals in the United States were enrolled. The median age was 44 years, 96% were male, and 83% were White. The median time on RAL + FTC/TDF treatment prior to enrollment was 34 months. Ninety-six percent of participants cited regimen simplification as the reason to enroll in the switch study. At base-line, the median CD4 count was 714 cell/µL and estimated glomerular filtration rate (eGFR) was 105 mL/min. At week 48, all assessed study participants remained viro-logically suppressed to the lower limit of quantification (HIV-1 RNA<50 copies/mL) and maintained high CD4 cell count (median, 751 cells/mL) and stable eGFR (median, 100.5 mL/min). STB was well tolerated with no discontinuations, no study drug-related serious adverse events, and no study drug-related grade 3/4 adverse events. CONCLUSIONS All participants switching to 1 tablet once-a-day STB from a twice-daily RAL + FTC/TDF regimen remained virologically suppressed. STB was well tolerated. Switching to STB may be a viable option for virologically suppressed patients wanting to simplify from a twice-daily RAL-containing regimen.
