Viral infection and acute peripheral facial palsy. A study with herpes simplex and varicella zoster viruses.
The role of herpes simplex virus (HSV) and varicella zoster virus (VZV) in acute peripheral facial palsy (APFP) was evaluated according to clinical symptomatology and serologic findings in a series of 70 patients seen over a one-year period. Peak morbidity of APFP occurred in the 21 to 30 years age group. Most patients were under 40 years of age and there were more female than male patients. Concomitant dysfunction of one or more other cranial nerves was present in most patients. The sera of patients were examined for IgG antibodies to HSV and VZV by the indirect immunoperoxidase technique. The geometric mean titer for VZV antibodies was significantly higher in the VZV-seropositive APFP patients than in the seropositive matched healthy control subjects. Nine APFP patients had increased or fourfold-rising VZV antibody titers on subsequent examinations, although six of them had presented without any evidence of zosterian eruption. The proportion of APFP patients with HSV antibodies at the time of admission was significantly higher than that of matched control subjects. No significant difference was found in the geometric mean titer for HSV antibodies between seropositive APFP patients and the seropositive control subjects. Only one patient in the series showed a fourfold rise in HSV antibodies, although the clinical symptomatology was compatible with this infection in 17 patients. The significance of serologic studies in determining the etiology of APFP is discussed.

Malignant fibrous histiocytoma of the maxillary sinus.
A rare localization of a malignant fibrous histiocytoma is presented. Review of the literature showed that the biological behavior of this group of tumors is obscure. The histomorphologic pattern does not always reflect the malignant character, the tendency for recurrence, and the metastasizing potential of the individual tumor. Radiotherapy is ineffective, so the surgeon must opt for radical excision. Additional clinical reports, long-term follow-up, and electron microscopic studies are needed to establish the biological behavior of this group of tumors.

Medullary carcinoma of the thyroid.
Three patients with medullary carcinoma of the thyroid gland, one sporadic and two familial, are described. One of the patients presented at a late stage of the disease with evidence of wide dissemination and severe diarrhea, which was controlled by indomethacin. The value of venous catheterization and plasma thyrocalcitonin measurements in evaluating the extent of the disease was demonstrated in this case.

Traumatic labyrinthine fistulas.
During the last 10 years, the rupture of the inner ear windows, as an entity, has been introduced in the differential diagnosis of the acute vestibulocochlear syndrome. Head trauma, Valsalva-like maneuvers and barotrauma due to diving accidents are now described as etiologic factors in the pathogenesis of labyrinthine fistula. Four cases were explored and repaired in the last four years in our department. Ataxia was the prominent symptom in three, while positional nystagmus and vertigo were consistent findings in all four cases. The definitive evidence of the fistula can be proved only by exploratory tympanotomy. In this report, the importance of the consideration of this entity in the differential diagnosis of vestibulocochlear syndrome in victims of traffic and diving accidents is emphasized.

Pure squamous cell carcinoma and mixed adenosquamous cell carcinoma of the thyroid gland.
Four cases of pure squamous cell carcinoma and two cases of mixed squamous cell and glandular carcinoma are reported. Obviously, there is a possibility that squamous cell carcinoma of the thyroid gland develops from the existing squamous cells or as a result of metaplasia of follicular cells. Metastases and direct extension of squamous cell carcinoma in the thyroid gland are much more frequent and must be excluded before the diagnosis can be established. Although the gross and microscopic pathology of these lesions presents no unusual features, follicles lined by metaplastic squamous cells offer strong presumptive evidence of a primary thyroid neoplasm. These tumors are comparatively radioresistant and biologically highly malignant. The treatment of choice is radical surgical resection, and these neoplasms must be treated more aggressively in the initial stage.

Bilateral chylothorax complicating radical neck dissection: report of a case with no concurrent external chylous leakage.
Bilateral chylothorax as a complication of radical neck dissection is extremely rare. Six cases are reported in the English literature. All of these patients' cases were associated with a concurrent external chylous fistula, as evidenced by the appearance of a milky fluid confirmed to be chyle by chemical determination. Chyle had also been noted to leak during the operation. This presentation illustrates an additional case of bilateral chylothorax occurring after radical neck dissection, and the first case, to our knowledge, with no concurrent external lymph leakage. Anatomic and physiologic considerations are presented and possible mechanisms of pathogenesis are discussed. Chylothorax has two major complications--respiratory and metabolic. A short summary of the modern concepts of treatment is presented.

Clear cell carcinoma of the thyroid gland.
Clear cell carcinoma is a rare variant of thyroid cancer, histologically related to the well-differentiated thyroid malignancies. The purpose of this paper is to discuss data collected from the English literature and to present three additional cases. In two of the three cases presented, thyroglobulin levels were extremely high after thyroid ablation. Both cases presented metastasis to lung and bone with significant I131 uptake. It seems that, when compared to the well-differentiated carcinomas of the thyroid gland, clear cell carcinoma has a more aggressive clinical course. Initial radical surgery is the treatment of choice for this kind of neoplasm and I131 should always be considered for the treatment of its metastasis.

Carcinoma of the prostate metastatic to the maxillary antrum.
Metastatic carcinoma of the maxillary antrum is an extreme rarity. Until 1980, less than 100 cases with distant primaries metastatic to the entire sinonasal tract had been reported. In a review of these cases, we found no mention of primary prostate cancer metastatic to the antrum. The purpose of this paper is to document the first case of this entity.

Laryngeal granular cell tumor in children.
Laryngeal granular cell tumor in childhood is rare. This article describes its occurrence in a 14-year-old girl. A review of the literature revealed five other cases. Clinical, endoscopic, histopathologic, and therapeutic considerations are discussed and compared with those in the adult form of granular cell tumor. Although this lesion is rare, awareness of it is necessary to avoid overtreatment.

Chondroma of the tongue. Report of two cases.
Lingual chondromas are very rare tumors. It can be assumed that chondromas of the tongue develop from heterotopic embryonal cartilage. Chondromas are usually seen on the lateral borders of the tongue. Because chondrosarcomas can appear in this location, wide excision of the lesions should be performed. The CO2 laser facilitates the excision, providing a dry surgical field. Two cases of lingual chondroma are presented and their probable cause discussed.

Respiratory distress due to diffuse cervical hyperostosis.
Cervical spondylosis and ankylosing hyperostosis of the cervical vertebrae are common findings. Although these hypertrophic changes can be completely asymptomatic, it is known that dysphagia may occur occasionally in the presence of massive cervical hyperostosis. Laryngotracheal symptoms due to cervical hyperostosis are less frequent and may be managed initially as tumors of the esophagus, trachea, or thyroid gland. The management of two severe cases of dyspnea due to cervical ankylosing hyperostosis are discussed.

Thyroid cancer in patients 70 years of age or older. Retrospective study of 50 patients.
This report presents our experience with 50 thyroid cancer patients 70 years of age or older, out of 606 patients of all ages. Comparing this series to those describing thyroid cancer patients of all ages, we found that thyroid carcinoma in the 70+ age group presents at a more advanced clinical stage, behaves more aggressively, and has a higher death rate. These findings are attributed mainly to the higher incidence of undifferentiated carcinoma and the more aggressive course of the differentiated types of carcinoma in the older age group. If suspected thyroid nodules are managed by initial radical treatment, carcinoma can be diagnosed earlier and patients will survive longer.

Production and manipulation of elevated temperatures in pig abdomen with a three-electrode capacitive heating device.
The ability of a three-electrode capacitive heating device operating at 13.56 MHz to produce and effect spatial redistribution of hyperthermic temperatures is demonstrated through abdominal heating studies conducted with 80 kg female and 65 kg male pigs. Temperature-time profiles over the respective heating periods were obtained in anterior and posterior superficial tissue and in selected abdominal organs. At selected times during heating, spatial redistribution of elevated temperatures was effected through adjustment of power settings for one or more of the three electrodes, i.e. through manipulation of the specific absorption rate (SAR) in-vivo.

Hashimoto's thyroiditis and carcinoma of the thyroid gland.
Seven cases of Hashimoto's disease (HT) occurring in association with carcinoma of the thyroid gland are presented. The diagnosis of HT was not reached before surgery in any of the cases; it was an incidental histopathological finding. There was no case of pure papillary cancer: two specimens showed mixed papillary and follicular cancers, four revealed follicular carcinomas (one of them with anaplastic areas) and one medullary neoplasm. Other authors, however, have reported that pure papillary carcinoma occurred with significantly greater frequency in thyroids also displaying Hashimoto's disease. Total thyroidectomy was performed in all seven patients and one patient with anaplastic follicular cancer also received external irradiation. TSH suppressive therapy was given postoperatively. All these patients are alive with no evidence of further disease after seven to 17 years of follow-up study, whereas the mortality in our total series of thyroid cancers, even in patients with low-grade malignancy, was about 9%. Thus the prognosis of patients with carcinoma of the thyroid gland with coexisting Hashimoto's disease is better than that of patients with carcinoma of the thyroid gland alone. Hashimoto's thyroiditis does not seem to be a premalignant lesion. There was no evidence suggesting that thyroid carcinoma originated in the proliferating epithelium of Hashimoto's thyroiditis. It would appear that thyroid carcinoma stimulates the development of HT in some patients and that the presence of the autoimmune inflammatory reaction and the circulating antibodies retard growth and dissemination of carcinoma of the thyroid gland.
