Methods: The control group consisted of 308 children who received an unilateral myringotomy due to a natural resolution in the contralateral ear. The experimental group consisted of 296 children who had a bilateral myringotomy, and a ventilation tube was not
inserted for DTs after laser myringotomy under topical anesthesia. The rate of DT and the recurrence rate of OME without tube insertion was the Acalabrutinib ic50 main outcome measure.
Results: In the control group, which showed a natural resolution, the rate of DT was 16.9% (52/308) of patients, and DT was more common in non-B tympanometry, which only had a recurrence rate of 17.3% (9/52). In the study group, 3.7% of patients showed unilateral DT (UDT) with contralateral positive effusion, and 5.4% of patients showed bilateral DTs (BDTs). BDT showed PXD101 Epigenetics inhibitor a non-B tympanometry pattern and a low rate of recurrence (25.0%), which was similar to the control group. UDT showed a B-type tympanometry in 81.8% of the patients, and the recurrence rate was significantly higher (68.2%; 15/22) than the BDT and control patients. BDT or DT with signs of natural resolution showed a low rate of OME recurrence regardless of tympanometry, and thus, patients do not need a VT.
Conclusions: DT was not rare even without
GA and the associated time delay, and DT was more common in the children that showed a natural resolution. However, microscopy and tympanometry was imperfect to predict dry tap, and thus, the surgeon needs to be prepared for individualized management of DT. UDT with B-type tympanometry and contralateral persistent effusion frequently recurred without tubes, and thus, VT for UDT appeared to be necessary. (C) 2011 Elsevier Ireland Ltd.

“Purpose:
To examine the efficacy of an alpha-1 blocker and its correlation to structural alteration of the prostatic urethra and the loss of energy in the urine flow using a virtual urethra processed from an endoscopic video image.
Materials and Methods: Video images of the prostatic urethra were recorded during cystourethroscopy in 11 patients with benign prostatic hyperplasia (BPH) before and after treatment with an alpha-1 blocker, naftopidil. The three-dimensional (3D) structure of the prostatic urethra was reproduced from video files. Fluid dynamic analysis and hydraulic energy calculations were performed using the “”virtual”" 3D urethral images.
Results: In 9 of 11 patients studied, an 11% improvement in the loss of energy (range, 1%-82%) was seen. Alpha-1 blocker treatment mediated the disappearance or decrease of the bulky vortex formation in seven patients, which led to an improved urinary stream. A positive correlation was found between improved energy loss and residual urine volume (P = 0.0312).
Conclusion: Alpha-1 blocker therapy led to a decreased energy loss in the urine flow in the prostatic urethra in relation to the improvement of clinical symptoms.
