    The 14 cases of malignant submandibular tumor whose treatment outcome we analyzed between 1989 and 2008 uncluded 5 of adenoid cystic carcinoma, 3 of squamous cell carcinoma, 2 each of mucoepidermoid carcinoma, and carcinoma ex pleomorphic adenoma, and 1 each of carcinosarcoma and large-cell carcinoma. One subject was diagnosed with T1, 7 with T2, 4 with T3, and 2 with T4. Lymph node involvement occurred in 5, -1 with N1 and 4 with N2. None had distant metastasis on the first visit.
    Seven were treated by surgery alone, 3 by surgery followed by radiotherapy, 2 by surgery followed by radio-and chemotherapy, and 1 by optimized supportive care. The surgical resection area was decided by tumor extension. Neck dissection was done in 9. Overall 5-year survival for all cases based on the Kaplan-Meier method was 57%. All with carcinoma ex pleomorphic adenoma, carcinosarcoma, or large-cell carcinoma remain alive. For those with adenoid cystic carcinoma 5-year survival is 80%, with mucoepidermoid carcinoma 50%, with squamous cell carcinoma 0%, and with carcinosarcoma 0%, respectively. The 5-year survival for stage I subjects was 100%, for stage II 83%, for stage III 50%, and for stage IV 0%.
    Surgical resection and postoperative radiotherapy were done in cases of minimal extraglandular extension or microscopically positive margins, with satisfactory results. Treatment efficacy for high-grade and advanced stage, however, requires more inprovement.

    We report a case of transient functional auditory agnosia and schizophrenia and discuss their relationship.
    A 30-year-old woman with schizophrenia reporting bilateral hearing loss was found in history taking to be able to hear but could neither understand speech nor discriminate among environmental sounds. Audiometry clarified normal but low speech discrimination. Otoacoustic emission and auditory brainstem response were normal. Magnetic resonance imaging (MRI) elsewhere evidenced no abnormal findings. We assumed that taking care of her grandparents who had been discharged from the hospital had unduly stressed her, and her condition improved shortly after she stopped caring for them, returned home and started taking a minor tranquilizer.
