Usefulness of an automated laser beam for decreasing outrageous fowl appointments with the disposable variety area of a hen village.
A 90-year old man with no significant past medical history presented to urology clinic complaining of gross hematuria, urinary frequency, and dysuria. Previous urine cytology was atypical but two white-light cystoscopies failed to show any lesions. The patient was taken for intraoperative blue light cystoscopy, which revealed multiple lesions that were then resected. Pathology revealed high grade urothelial carcinoma with lamina propria invasion and the patient was managed successfully with Bacille Calmette Guerin therapy. This case highlights an important role for blue light cystoscopy in diagnosing patients with high suspicion for malignancy but negative white light cystoscopy. Intrauterine devices(IUD) are used by women worldwide as the most conventional method of reversible contraception. Migration of an IUD to pelvic or abdominal organs is considered rare. We report a case of a 67 year old female who had neglected to remove her IUD for 20 years. She visited our clinic because of recurrent UTI's the previous year. After assessment and clinical investigation it was found that the coil had a late onset migration to the urinary bladder, with calculus formation, causing the patients' symptoms. In our case we cystoscopically removed the encrusted coil after performing endoscopic cystolitholapaxy. The patient had an uneventful recovery and her UTI's subsided. The objective of this article is to report the first case of intravesical IUD migration at our clinic and raise awareness of forgotten contraceptive devices and their potential complications. Anterior urethral valves are a rare cause of obstructed voiding in adolescent children and are often unheard by adult urologists. In this case report, we discuss the management of two adolescent patients who were referred to us with obstructive voiding symptoms with a diagnosis of neurogenic bladder and posterior urethral valves respectively but on evaluation were found to have anterior urethral valves. This article highlights the need for considering anterior urethral valve as an important differential diagnosis in children and adolescents presenting with obstructive voiding symptoms so as to avoid delay in diagnosis and management in young boys. Adenocarcinomas represent 2% of bladder cancers and originate from the bladder urothelium or the urachus.1 Urachal adenocarcinoma constitutes less than 0.5% of all bladder cancers.2 We report a urachal adenocarcinoma case managed surgically with two incisions and an emphasis on cosmesis while maintaining oncologic principles. BACKGROUND/OBJECTIVE Ureteral triplication is a rare congenital malformation with a wide spectrum of presentation that requires a high index of suspicion in order to diagnose. selleckchem To date, only about 100 cases have been published in medical literature. Smith et al.1 proposed a classification for ureteral triplication that describes it as three separate ureters and three separate ureteral orifices with no interconnection between ureters. In this video, we present a surgical approach for laparoscopic partial nephrectomy of both upper moieties in the context of ureteral triplication. MATERIALS AND METHODS The procedure is initiated with cystoscopy and retrograde pyelogram to better determine the pertinent anatomy. A ureteral catheter is inserted into the healthy ureter to facilitate its identification and reduce the risk of inadvertent injury. The patient is placed in the modified flank position. A 5 mm camera port is inserted using the Hasson technique and two additional ports are inserted under vision. The colon is deflected medially, and the kidney, ureters and blood supply are identified. Both upper pole ureters are transected. Variance of the blood supply can be encountered; therefore, highly selective dissection of the vessels is performed, and care is taken to preserve the main renal vessels. Upper pole partial nephrectomy is carried out using a harmonic scalpel at the demarcation line. RESULTS Operative time was 182 minutes. Discharge was on post-operative day 2 without intra or post-operative complications. Follow-up ultrasound 3 months post-operation demonstrated a normal lower pole moiety without hydronephrosis or hydroureter. CONCLUSIONS Laparoscopic partial nephrectomy with highly selective dissection of vessels in the context of a ureteral triplication anomaly is feasible and safe. Abnormal blood supply should be considered and addressed accordingly. The neurobiology of sex differences during language processing has been widely investigated in the past three decades. While substantial sex differences have been reported, empirical findings however appear largely equivocal. The present systematic review of the literature and meta-analysis aimed to determine the degree of agreement among studies reporting sex differences in cortical activity during language processing. Irrespective of the modality and the specificity of the language task, sex differences in the BOLD signal or cerebral blood flow was highly inconsistent across fMRI and PET studies. On the temporal side, earlier latency of auditory evoked responses for female compared to male participants were consistently observed in EEG studies during both listening and speaking. Overall, the present review and meta-analysis support the theoretical assumption that there are much more similarities than differences between men and women in the human brain during language processing. Subtle but consistent temporal differences are however observed in the auditory processing of phonetic cues during speech perception and production. To integrate auditory and visual signals into a unified percept, the paired stimuli must co-occur within a limited time window known as the Temporal Binding Window (TBW). The width of the TBW, a proxy of audiovisual temporal integration ability, has been found to be correlated with higher-order cognitive and social functions. A comprehensive review of studies investigating audiovisual TBW reveals several findings (1) a wide range of top-down processes and bottom-up features can modulate the width of the TBW, facilitating adaptation to the changing and multisensory external environment; (2) a large-scale brain network works in coordination to ensure successful detection of audiovisual (a)synchrony; (3) developmentally, audiovisual TBW follows a U-shaped pattern across the lifespan, with a protracted developmental course into late adolescence and rebounding in size again in late life; (4) an enlarged TBW is characteristic of a number of neurodevelopmental disorders; and (5) the TBW is highly flexible via perceptual and musical training.
