Abstract

Thin film bulk acoustic resonator (TFBAR) with c-axis tilted AlN finite element modeling was performed using COMSOL Multiphysics simulation software. Depending on the AlN c-axis tilt angle, dual mode TFBAR can be obtained that operate in longitudinal and shear mode: the former mode is a thickness-extensional mode, while the latter is a thickness-in plane-shear mode that is suitable for liquid sensing applications. The acoustic wave displacement, the resonator frequency and equivalent admittance of the TFBARs with different tilt angles and electrode thicknesses were simulated to obtain the optimum design (high electroacoustic coupling efficiency and large quality factor Q) for shear mode operation. Furthermore, AlN films having the c-axis tilted up to about 30̊ from the substrate normal were successfully grown on silicon (100) substrates by reactive rf magnetron sputtering technique at 200̊C.

Abstract

Summary Objectives Vocal fold paralysis can have an important impact on a patient's quality of life. The goal of this study was to compare, in terms of vocal improvement and motility recovery, the post-vocal treatment results of our patients with unilateral vocal fold paralysis (UVFP) when treatment was started early (within 4 weeks from injury) versus intermediate (from 4 to 8 weeks) or delayed (at least 8 weeks after injury) treatment. Study Design An 11-year retrospective study of patients with UVFP who underwent multidimensional diagnostic-therapeutic assessment. Methods In total, 171 patients with UVFP were included in our study, divided into three groups who underwent early (first group), intermediate (second group), or delayed (third group) voice treatment. All patients underwent voice therapy based on forcible exercises supplemented by manipulations and maneuvers. Results Of the 171 patients with UVFP, 106 (62%) recovered vocal fold motility. Of these 106 patients, 51/78 (65%) were in the first group, 30/49 (61%) in the second group, and 25/44 (56%) in the third group. A significant ( P < 0.0001) reduction in fundamental frequency (Fo) was present in the first group with a manifest improvement in the mean values of Jitter (Jitt%; P = 0.001), Shimmer (Shim%; P < 0.0001), and noise-to-harmonic ratio (NHR; P < 0.0001). A significant ( P < 0.0001) reduction in Fo was found in the second group with a manifest improvement in Jitt% ( P < 0.001), Shim% ( P < 0.0001), and NHR ( P < 0.0001). For the third group, no values were statistically significant apart from the improvement in NHR ( P < 0.001). Conclusions This study confirms the importance of early rehabilitation underlining the non-functional vocal recovery in patients who started treatment later than 8 weeks after injury.

11. Bronchial selective ventilation in a wide tracheocutaneous fistula.

Abstract

Abstract: We present the treatment and management of a wide tracheocutaneous fistula after tracheotomy correlated with excessive cuff pressure in a 36-year-old woman with cerebral palsy since infancy in which persistent type II respiratory failure required continuous ventilatory support. We discuss the surgical treatment adopted for the management of this particularly wide lesion. At the end of surgery, mechanical ventilation through a tracheal cannula was hindered by the reduced length of the residual trachea below the tracheotomy. The need to guarantee mechanical ventilation to the patient led to the implementation of a cuff securing system in the two main bronchi. We describe the approach that may be attempted under extreme conditions, when traditional ventilation methods cannot be applied for anatomical reasons. [Copyright &y& Elsevier]

29. A case of syryngocystadenoma papilliferum (SCAP) involving middle ear, presenting with otomastoiditis and cerebral abscess

Abstract

Abstract: Syryngocystadenoma papilliferum (SCAP) is an uncommon cutaneous adnexal neoplasm of apocrine gland origin. Until now, fewer than 200 cases have been reported in international literature, of which 12 cases involved the external ear. No cases of SCAP involving the middle ear have been reported. We describe a case of SCAP of external and middle ear, presenting with otomastoiditis and cerebral abscess; this aggressive behavior, never reported for a benign adenoma of the external or middle ear, could lead to a differential diagnosis with cholesteatoma or malignancies.
