RESUMO
AIMS AND BACKGROUND: Primary squamous cell carcinoma of the thyroid gland (PSCCT) is an uncommon malignancy characterized by a poor prognosis. A radical surgical approach combined with radiotherapy or chemotherapy is the generally accepted treatment for this tumor. The epidermal growth factor receptor (EGFR) is a transmembrane tyrosine kinase receptor modulating the cell proliferation and biological progression of many human epithelial tumors. The EGFR overexpression in PSCCT suggests an additional therapeutic option for the treatment of this tumor. METHODS AND STUDY DESIGN: The clinicopathological features and immunohistochemical profiles of two cases of primary squamous cell carcinoma of the thyroid in a 66-year-old and an 83-year-old woman are presented. EGFR status was valued in both cases. RESULTS: Overexpression of EGFR protein was detected in 50% and 75% of the tumor cell membranes. EGRF gene polysomy was detected in both tumors. CONCLUSIONS: Pharmaceuticals targeting EGFR may help to provide the rationale for an additional, novel therapeutic option for this rare tumor, especially when other therapeutic options have been exhausted.

Management of intraparotid facial nerve schwannomas (IFNS) is very challenging because the diagnosis is often made intra-operatively and in most cases, resection could lead to severe facial nerve (FN) paralysis, with important aesthetic consequences. Articles in the English language focused on the management of FN schwannoma have been selected and critically reviewed. A decision-making algorithm is proposed. In the case of type A or B neoplasms, or in case of a pre-operative FN House-Brackmann (HB) grade IV or worse, the authors would favor a resection of the IFNS and (where necessary) a reconstruction of the nerve. In the case of pre-operative HB grade III or better and type C or D neoplasms, patients would undergo an intra-operative biopsy to rule out malignancy, and a possible conservative management could be adopted. Localization and adherences of IFNS, as well as pre-operative FN function are important factors that must be considered in the decision-making process for IFNS to optimize the functional outcomes.

OBJECTIVE: We evaluated the efficacy of voice therapy according to Borragan's method associated to S. Magnani's vocal counselling in functional dysphonia in children. PATIENTS AND METHODS: We prospectively treated 16 patients with vocal fold nodules (10 males, 6 females). Age ranged from 6 to 11 years with a mean age of 9 years. We performed a full screening phoniatric evaluation. In addition psychological tests were carried out to investigate psychological background. RESULTS: We lost three patients at follow-up; one patient received surgery, eight patients healed (43.75%), four improved (25%). There was no statistical difference in the analysis of electroacoustical parameters while MPT significatively raised after therapy. CONCLUSION: If patients have motivation voice therapy could improve functional dysphonia in children. It is also important psychological background. Further studies on bigger populations with long-term follow-up are needed.

Obesity is recognized as playing an important role in causing snoring and in turning simple snoring into obstructive sleep apnea syndrome (OSAS). From our series of patients with sleep disturbances, we studied a group of 43 normal-weight snorers in whom we detected a significant number of OSAS episodes. An articulated diagnostic protocol was adopted, and Müller's maneuver was extensively applied. The resulting data were compared to data from a group of 43 obese patients from the same series. The major risk factor for developing OSAS in normal-weight snorers appears to be anatomic abnormalities, in particular, septal deviation and base of tongue hypertrophy. Soft palate hypertrophy alone is not enough, although in obese snorers it can produce a sleep disorder. The normal-weight snorer needs to be thoroughly investigated because of the significant risk of developing OSAS and for the detection of multiple concomitant sites of obstruction.

Giant-cell tumor of the tendon sheath (GCTTS) and pigmented villonodular synovitis belong to the same type of benign proliferative lesions originating in the synovia that usually affect the joints, bursae, and tendon sheaths. They frequently involve the hands, knees, ankles, and feet. We report a case of GCTTS in the external auditory canal in a 53-year-old woman who presented with hearing loss, fullness, and a sessile lesion protruding from the anterior wall of her external ear canal. The 1.5-cm diameter mass was spherical, well encapsulated, firm, and covered with normal skin. The lesion was completely excised, and the patient's symptoms resolved. No recurrence was detected at 2 years of follow-up.
