Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of repositioning maneuvers for benign paroxysmal positional vertigo of posterior semicircular canal: advantages of hybrid maneuver.
The prevalence of benign paroxysmal positional vertigo (BPPV) is becoming more frequent in elderly population. The presence of comorbid factors has to be considered before assessment as well as before commencing any repositioning treatment. Our aims were evaluation of the maneuvers efficacy and evaluation of the applicability of hybrid maneuver (HM) in patients with physical limitation. ⋯ All maneuvers evaluated demonstrated similar efficacy. The HM, as our data showed, allows us to obtain a good percentage of success similar to most maneuvers used. It is also more comfortable for the patients with hip or neck functional limitation allowing an effective treatment of the posterior canal BPPV.

Traumatic tympanic membrane perforations: a study of etiology and factors affecting outcome.
The purposes of this study were to determine the factors involved in the spontaneous healing and to profile the various etiologies of traumatic tympanic membrane (TM) perforation. ⋯ In our experience, domestic violence and street fight were the most common causes of the traumatic TM perforation. Traumatic TM perforations have excellent prognosis. However, preexisting tympanosclerosis and the perforation that involved malleus or umbo damage could lengthen the healing time of perforation, Wet perforations with bloody or watery discharge accelerate the healing, but the curled edges did not affect the outcome of spontaneous healing.

Comparative Study
Delayed lymph node metastases after elective neck dissection in patients with oral and oropharyngeal cancer and pN0 neck.
Patients with surgically treated head and neck cancer and clinical N0 neck with high risk of occult lymph node metastasis undergo elective neck dissection (ND). Late lymph node metastasis may appear in those patients with pN0 neck. The aim of the present study was to analyze the incidence and clinical relevance of late lymph node metastasis in patients with head and neck cancer. ⋯ Even in the case of pN0 neck after an elective ND, the appearance of late lymph node metastases must be expected. The low proportion of patients with late lymph node metastases after a selective ND in clinical and histologic N0 does not justify an extended form of neck surgery.
