The long noncoding RNA nHOTAIRM1 is necessary for differentiation and activity of iPSC-derived spinal motor neurons.

The mammalian nervous system is made up of an extraordinary array of diverse cells that form intricate functional connections. The programs underlying cell lineage specification, identity and function of the neuronal subtypes are managed by regulatory proteins and RNAs, which coordinate the succession of steps in a stereotyped temporal order. In the central nervous system (CNS), motor neurons (MNs) are responsible for controlling essential functions such as movement, breathing, and swallowing by integrating signal transmission from the cortex, brainstem, and spinal cord (SC) towards peripheral muscles.

Early and late urodynamic assessment of Padua ileal bladder.

Objectives: To report the data from a single series of 46 patients who underwent cystectomy and Padua ileal bladder (PIB) substitution during a 48-month period. Data are lacking concerning the changes in urodynamic characteristics of the orthotopic ileal neobladder.

Methods: From January 2002 to April 2003, 46 consecutive male patients underwent radical cystectomy and PIB substitution for muscle-invasive bladder cancer.

Patients with bladder outlet obstruction who refuse treatment show no clinical and urodynamic change after long-term follow-up.

Objective: To evaluate in patients with mild bladder outlet obstruction (BOO) who refused the proposed treatment and were on watchful waiting (WW), the symptomatic and urodynamic changes after 1-5 years of follow-up.

Methods: 102 patients with lower urinary tract symptoms (LUTS) and BOO (Schafer class: 2-6, median 3) were clinically and urodinamically re-evaluated after 1-5 years of follow-up. Of these, 82 were submitted to medical (alfuzosin or finasteride) or surgical treatment (prostatectomy or TUIP) and 20, who refused the proposed treatment, were on WW.

The evolution of detrusor overactivity after watchful waiting, medical therapy and surgery in patients with bladder outlet obstruction.

Purpose: We analyzed the evolution of detrusor overactivity in patients with bladder outlet obstruction treated with either medical or surgical therapy or watchful waiting.

Materials And Methods: Of 255 patients with symptomatic benign prostatic enlargement who completed the International Prostate Symptom Score and underwent full urodynamic investigation 161 presented with bladder outlet obstruction. Of the 161 men 101 were reevaluated with a second clinical evaluation and urodynamics 1 to 5 years (mean 2) after watchful waiting in 20, medical treatment (alfuzosin 20 and finasteride 16) in 36 and surgery (transurethral incision of the prostate 13 and prostatectomy 32) in 45.

Scrotoscopy: a promising future? Our preliminary experience.

Scrotoscopy is a new endourologic technique for the exploration of the scrotum. After distention of the tunica vaginalis space with saline, a standard arthroscope was employed in 20 cadavers and subsequently in 5 patients before full surgical exploration for hydrocele (1 case), testicular biopsy (3 cases), or orchidectomy (1 case). There was a clear view of the testis and epididymis.
