RESUMEN

The role of cVEMPs and vHIT in the evaluation of otosclerosis and its eventual vestibular impairment: preliminary findings. OBJECTIVES: Otosclerosis is one of the most common causes of hearing loss in adults, with a prevalence of 0.3% to 0.4% in Caucasians. Vestibular symptoms may occur, with an incidence ranging between 5% and 57% of patients. The aim of our study is to evaluate the vestibular function and its eventual changes after stapes surgery in patients affected by otosclerosis. METHODS: Prospective case-control study. Twenty patients (17 females; age range 33-58; mean age 44) who underwent surgery for otosclerotic disease between April 2012 and February 2014 were prospectively studied. These patients underwent preoperative and postoperative audiological tests. Furthermore, vestibular function was evaluated using the cervical evoked myogenic potentials test (cVEMPs) and video head impulse test (vHIT), preoperatively and postoperatively. A case-control study was also performed. Quantitative and statistical analysis of patients' vestibular function was carried out both before and after stapes surgery. RESULTS: The means of the vHIT gains in the case group were 1.03 on the right side and 1.01 on the left side. A significant difference between case and control groups was seen, with a lower left gain registered in the control group. No cases with a gain of less than 0.8 were found in either group. Moreover, a significant postoperative reduction in P1/NI amplitude was seen in patients complaining of postoperative dizziness or vertigo. CONCLUSIONS: These findings indicate a probable traumatic saccular impairment in patients with vestibular symptoms. However, a longer follow-up may help in understanding the behaviour of cVEMPs in post-stapes surgery vertigo.

RESUMEN

Human immunodeficiency virus (HIV) infection has historically been related to the development of specific cancers, some of which are so closely linked to the infection, such as Kaposi's Sarcoma (KS), that they have earned the name Acquired Immuno-Deficiency Syndrome (AIDS)-defining cancers (ADCs). While the development of antiretroviral therapy (ART) has decreased the incidence of AIDS-defining cancers, the resulting aging of people living with HIV (PLWH) highlighted an increased occurrence of other forms of cancer. At the "Gaetano Martino" hospital in Messina, we developed a multidisciplinary approach by creating a bridge between the Oncology Unit and the Infectious Diseases Unit to carry out screening and a more rapid diagnostic and therapeutic journey for cancers in PLWH. The goal is to improve the diagnosis of various types of cancer by involving other professionals, such as gastroenterologists and gynecologists, to ensure faster access to treatment and, therefore, a greater chance of survival. In addition, our multidisciplinary approach has also included vaccine screening, offered by the "Gaetano Martino" hospital and useful for preventing the development of specific forms of cancer in the entire population and particularly in PLWH.

RESUMEN

BACKGROUND: P53, a crucial suppressor of tumor formation, generates multiple isoforms, whose role in disease is still being defined. METHODS: By immunohistochemistry, we studied the expression of P53 protein and relative isoforms in benign papillomas (PA, n=9), inverted papilloma (IPA, n=10) and squamous cell carcinomas (SCC, n=21). RESULTS: In all lesions, P53 isoforms were significantly more expressed than P53. Immunoexpression of P53 matched with P53 isoforms in IPA as well as in SCC. Simultaneous immunoexpression of P53 and related isoforms was double in SCC compared to IPA (10% vs 24%), while expression of P53 isoforms was strongly reduced (70% vs 43%). IPA showed the highest percentage of both reactive cases and immunostained cells expressing P53 isoforms. CONCLUSIONS: We found the higher expression of P53 isoforms in IPA and SCC compared to PA, suggesting their role in local aggressiveness and malignant proliferation in head-neck lesions.

RESUMEN

Background In 2002, we reported the initial results of a trial comparing radical prostatectomy with watchful waiting in the management of early prostate cancer. After three more years of follow-up, we report estimated 10-year results. Methods: From October 1989 through February 1999, 695 men with early prostate cancer (mean age, 64.7 years) were randomly assigned to radical prostatectomy (347 men) or watchful waiting (348 men). The follow-up was complete through 2003, with blinded evaluation of the causes of death. The primary end point was death due to prostate cancer; thesecondary end points were death from any cause, metastasis, and local progression. Results: During a median of 8.2 years of follow-up, 83 men in the surgery group and 106 men in the watchful-waiting group died (P=0.04). In 30 of the 347 men assigned to surgery (8.6 percent) and 50 of the 348 men assigned to watchful waiting (14.4 percent), death was due to prostate cancer. The difference in the cumulative incidence of death due to prostate cancer increased from 2.0 percentage points after 5 years to 5.3 percentage points after 10 years, for a relative risk of 0.56 (95 percent confidence interval, 0.36 to 0.88; P=0.01 by Gray's test). For distant metastasis, the corresponding increase was from 1.7 to 10.2 percentage points, for a relative risk in the surgery group of 0.60 (95 percent confidence interval, 0.42 to 0.86; P=0.004 by Gray's test), and for local progression, the increase was from 19.1 to 25.1 percentage points, for a relative risk of 0.33 (95 percent confidence interval, 0.25 to 0.44; P<0.001 by Gray's test). Conclusions: Radical prostatectomy reduces disease-specific mortality, overall mortality, and the risks of metastasis and local progression. The absolute reduction in the risk of death after 10 years is small, but the reductions in the risks of metastasis and local tumor progression are substantial.
