Background: Nowadays, short bulbar strictures refractory to one endoscopic treatment attempt could be managed with non-transecting urethroplasty technique as a first option. Jordan et al and Bugeja et al described a dorsal approach, sparing vessels, and spongiosum in the hope of a decrease of surgical side effects.
Objective: To describe the step-by-step technique of the ventral approach for the non-transecting bulbar urethroplasty in distal and mid short bulbar strictures.
Materials And Methods: We performed a prospective observational study of a cohort of patients who underwent a ventral non-transecting bulbar urethroplasty for short mid or distal bulbar strictures from January 2016 to December 2018. We included 10 patients.
Surgical Technique: A ventral midline urethrotomy is made and extended to assure a good caliber lumen both distally and proximally (20 Fr). The mucosal scar tissue is marked and a mucosectomy is performed, preserving the spongiosum.We bring the distal and proximal edges of healthy mucosa together without tension with a 5/0 absorbable monofilament. Ventral stricturotomy is closed over a 20F catheter, in a Heinike-Mikulics fashion, with 5/0 absorbable monofilament for the mucosal anastomosis and a 4/0 absorbable monofilament for the spongioplasty.
Results: Mean age was 56,50 years (+/-17,27) and mean stricture length was 1,06cm (+/-1,82). The majority of strictures (90%) were located in the mid bulb. After a mean follow up of 27,25 months (+/-12,12), 9 patients remain recurrence-free (87,5%). A significant mean increase in Qmax was observed (12+/-4,53 ml/s, p=0,04). Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROMS), items (Questions 1-6) related to urinate symptoms also showed a significant improvement(p=0,03). We didn't find any significant decrease in erectile function with this technique.
Conclusion: The ventral approach for mid and distal short bulbar strictures is a feasible and reproducible technique with a significant increase in Qmax and improvement in USS-PROMS. Preliminary results show no decrease in erectile function.

Impact of muscle fatigue on anticipatory postural adjustments during gait initiation.

Introduction: Prolonged or strenuous exercise leads to a temporary decrease in muscle function and performance, which interferes with activity of both prime movers and postural muscles. This effect of fatigue has been reported both for single segment movements and for locomotion. However, little is known regarding the effects of fatigue on anticipatory postural adjustments (APAs) during gait initiation, a task in which the control of focal movement should be strictly coupled to a feedforward control of posture.

Purpose: To compare the erectile and urinary functions of ventral and dorsal onlay buccal mucosal graft (BMG) urethroplasty in the management of proximal bulbar urethral strictures (PBUS) in sexually active men.
Patients And Methods: We retrospectively included patients with primary non-traumatic PBUS who were treated with (BMG) urethroplasty at our department between March 2019 and March 2023 either ventral or dorsal approaches. Patients were assessed at 3- and 12-months postoperatively for urinary and erectile functions.
Unlabelled: Motivated behaviors are regulated by distributed forebrain networks. Traditional approaches have often focused on individual brain regions and connections that do not capture the topographic organization of forebrain connectivity. We performed co-injections of anterograde and retrograde tract tracers in rats to provide novel high-spatial resolution evidence of topographic connections that elaborate a previously identified closed-loop forebrain circuit implicated in affective and motivational processes.

Opioid use disorder (OUD) is considered a global health issue that affects various aspects of patients' lives and poses a considerable burden on society. Due to the high prevalence of remissions and relapses, novel therapeutic approaches are required to manage OUD. Deep brain stimulation (DBS) is one of the most promising clinical breakthroughs in translational neuroscience.

Background: Adenoid cystic carcinoma (ACC) is a rare malignant tumor that accounts for <1 % of head and neck malignancies, with an estimated involvement of the tongue at approximately 3 %.
Case Presentation: This report presents a case of a 42-year-old male with no significant history of tobacco or alcohol use, who developed a painless, progressively enlarging mass on the ventral surface of his tongue over the course of eight months. Initial surgical resection confirmed the diagnosis of ACC, which necessitated a right hemiglossectomy followed by radiotherapy to address potential residual disease.
