Purpose: To understand the real efficacy of transtympanic steroid therapy for sudden sensorineural hearing loss (SSHL) in patients in whom traditional therapies have failed. Procedures: A prospective study was designed in order to evaluate hearing improvement in SSHL patients treated with transtympanic therapy. A solution of methyl-prednisolone (MP) and sodium bicarbonate was administered via a transtympanic injection to 8 patients. Hearing level was evaluated before therapy and at days 1, 7 and 30. Results: Hearing improvement was obtained in 75% of the patients. The patients in this category are usually considered untreatable. Conclusion: Transtympanic steroid therapy is an efficacious solution for patients affected by SSHL in whom traditional therapies have failed. Further studies will be required to identify the most favourable dosage, route of administration and type of steroid. Transtympanic steroid application is safe, inexpensive, easy to perform and efficacious in cases of SSHL not responsive to traditional therapy.

Objectives: Paradoxical vocal fold dysfunction (PVFD) is a disorder in the larynx featuring involuntary adduction of the vocal folds during the inspiratory phase of breathing. The symptoms include acute episodes of dyspnea and bouts of coughing. To date, there is no universally acknowledged treatment for PVFD, though respiratory retraining therapy is the treatment of choice. Aims: The purpose of this work was to evaluate the results of long-term respiratory retraining therapy in cases of PVFD. Patients and Methods: We treated 20 patients with PVFD for 2 years: 10 subjects were submitted to a cycle of respiratory retraining therapy every 12 months (receiving a total of 3 cycles) while 10 were given a cycle every 3 months (for a total of 9 cycles) no matter what their clinical conditions were. Results: The results show that long-term respiratory retraining is particularly efficacious if the cycles of treatment are repeated, no matter what clinical conditions are present. In fact, when only one cycle of retraining treatment is given a year, there is initial improvement followed by progressive worsening. Conclusions: Long-term respiratory rehabilitation is effective, especially if the treatment is given at least once every 3 months.

We describe an Italian family in which two sisters have macrocephaly due to hydrocephalus, and sensorineural hearing loss in addition to other brain abnormalities demonstrated by Magnetic resonance imaging (MRI). The girls, born to healthy non-consanguineous parents, have borderline psychomotor development delay (probably due to hearing defect) and minor dysmorphisms. The clinical picture fits the Chudley-McCullough syndrome, an autosomal recessive condition, to date described in only five families. Our data, in particular the neuroradiological findings, include all brain anomalies variably reported in previous works (hydrocephalus, corpus callosum partial agenesis, interhemispheric cyst, cerebral and cerebellar cortex dysplasia), thus illustrating the full phenotype of the syndrome.

Objective: The larynx is considered a secondary sexual organ. To demonstrate that sex hormones can directly influence laryngeal function, specific receptors in the vocal cord must be identified. Materials and Methods: We searched for estrogen, progesterone and androgen receptors, using an immunohistochemical method, in normal human vocal cords (from 3 cadavers) and in samples of healthy vocal cords and of laryngeal carcinomas from 15 live subjects. Breast and prostate carcinoma were used as controls. Results: In all the normal samples tested, the results were negative; there was only a nonspecific cytoplasmatic response in the subepithelial glands (false positives). In the neoplastic tissue, 2 samples had a weak nuclear focal positivity for estrogen and progesterone receptors; all 15 subjects studied were negative for androgen receptors. Conclusions: Since our data show that sex hormone receptors are absent in the vocal cords, other theories must be considered to explain the fact that hormones influence the quality of the voice. This study discusses the possibility that the changes of voice according to gender and throughout life might be linked with a different expression of some growth factors in the laryngeal tissue and that this expression might in turn be influenced by hormonal variations.
