[Base tongue actinomycosis].

Actinomycosis is a bacterial, suppurative chronic infectious disease caused by Actinomyces israelii. Actinomycosis of the tongue is an uncommon form, and only 3% affect the base of the tongue. We report a case with dysphagia from an epiglottis, vallecula and tongue base mass. Diagnosis was made on histologic examination of a tissue biopsy. The disease completely resolved after chirurgical incision and drainage of the abscess and one month of oral amoxicillin therapy. The recurrence of the disease, five years later, made necessary a second surgical procedure and one year of penicillin therapy. We comment the possible causes of this recurrence.

[Unusual presentation forms of Wegener's disease].

Wegener's granulomatosis may appear with the classic granulomatous necrotizing vasculitis affecting both high and low airway and renal glomerule, and rarely small vessels in any other location. In this way we may find generalized and localized forms of the disease. Three atypical cases of the disease are reported. The first one as a limited form with only airway affection. The second one as an unusual case of otitis with progressive affection of I, II, V, VI, VII and VIII cranial nerves. The third one was a generalized case with sinusitis and orbital pseudotumor. Both first and second cases have been controlled for a very long period of time of 22 and 14 years respectively, and none of them has presented any other location of the disease.

[Distant metastases in patients with advance laryngeal carcinoma].

Patients with advanced stage cancer larynx have a higher risk of development of distant metastases which means a bad prognosis. In our study we try to identify risk factors with the idea of involve to all of these patients in more aggressive systemic therapy protocols. Data of 57 patients surgically treated, with squamous pharyngolaryngeal carcinoma, stage III and IV, are evaluated. Advanced T stage or more extensive neck disease more often caused distant metastases (p < 0.05), and also the histological evidence of tumor invasion in three or more cervical nodes (p = 0.02), and poorly differentiated tumors (p < 0.05). Tumor site, surface area in cm, presence of ulceration, and loco-regional uncontrol were not associated with distant metastases.

[Pharyngoesophageal foreign bodies].

A review was made of 77 rigid esophagoscopies to remove a foreign body from the upper digestive tract. Mean age of patients was 59 years. Meat bones were the most frequent impacted foreign body and the cervical esophagus was the most frequent site of impactation. No foreign body was found in 22% of esophagoscopies, a high rate that could have been due to our lack of confidence in radiographic studies, which yield false positive and false negative information. Esophagoscopy is performed whenever patient-referred symptoms are clear. The only complications were three cases of major esophageal erosions without perforation and one pneumothorax. A case of intramural esophageal pseudodiverticulosis was found.

[Wegener's disease: localized and generalized forms].

Two new cases of Wegener's granulomatosis are reported. One of them with the classic sinusal, pulmonary and renal involvement, and the other one as a limited form of the disease, only with respiratory affection, sparing the characteristic renal entailment, although its prolonged survival. The AA, comment literature controversial about if the forms limited to the ENT-area represents a unique and separate entity or an early and modified state of the disease.

[The influence of hypercholesterolemia and noise on human auditory function].

A cross-sectional study on occupational noise exposure and hypercholesterolemia was conducted in a group of 1.209 workers exposed to industrial noise. Clinical examinations and audiograms were compared in exposed and not exposed subjects to noise. There was a strong relationship between severe noise induced hearing loss and hypercholesterolemia in all de workers. But the relationship was not convincing when the workers were considered stratified in groups of age, because the number of hard of hearing labourers with high levels of cholesterol, increases as they get older. The AA, support the point of view that the age is an important confounding factor, and in their study there is no relation between noise induced hearing loss and hypercholesterolemia.

[Neurofibroma of the tongue].

Neural sheath tumors are rarely encountered in the oral cavity. The most common location is the tongue and thereafter, the sites in order of frequency are the buccal mucosa, the floor of the mouth, palate, lips and gingiva. The need to differentiate between Neurofibroma and Schwannoma is imperative in as much as the first one shows a much greater propensity for malignant transformation when associated with von Recklinghausen's neurofibromatosis. We present a case of Neurofibroma localized in the tongue which appeared as a sessile nodule of 0.3 X 0.4 cm. After extensive surgical ablation there was no further recurrence in 5 years follow-up.

[Jugular paraganglioma: presentation in the form of an aural polyp].

Paraganglioma though rare in ENT-pathology are considered the most common middle ear tumors. A few of them show some particularities in its growing mood, for instance under the appearance of a banal polyp lodging in the external ear canal, perhaps the polyp represents only the outer portion of a deeper larger process encroaching the underlying bone, which threat heavy complications, specially at attempts of removal without the prior due complementary explorations. The case reported by the authors was a quickly evolutive syndrome with the polyp associated to otorrhea and facial paresia. The verification of the bone destruction make credible the actual diagnosis, malignant tumor of the temporal bone. Afterwards profuse otorragia suggested the glomic tumor. The paper emphasizes the clinic malignancy of theses growths in spite of their histologic benignity, owing both to its speed evolution and destructive power.

[Rare benign tumors in otorhinolaryngology: plasma cell granuloma and histiocytoma].

Two benign tumors in the face are reported. Plasma cell granuloma is a rare benign tumor that affects people at all ages and most frequently involves the lung. It is dominated by mature plasma cell proliferation. The AA. report a case appearing as a painless nontender mass in the right cheek, with purplish discoloration of the overlying skin. Differential diagnosis with Plasmocytoma was considered. Histiocytoma are most common seen on the lower extremities of young adults. Reporting a case localized on the skin of the root of the nose. Differential diagnosis with osteoma is made.

[Open wound of the larynx caused by the horn of a bull].

Open laryngeal traumas are seldom seen in E.N.T., specially those ones secondary to horn bull goring. We do a synthetized study with regard to report this original case treated in our Service. We justify the paper because of the intensity, the seriousness and the originality of the picture.

[Peristomal recurrence after total laryngectomy].

The AA. evaluate the incidence of peristomal recurrences among 349 total laryngectomies operated between 1975 and 1985, at ENT Service, Hospital Dr. Peset, Valencia. As possible etiologies they emphasize: first of all the infraglottic spreading of the tumor, the emergency tracheostomy done prior to the surgery of the larynx, and the lacking of irradiation of the tracheostoma.

[Mucoceles of the maxillary sinus. Report of a case].

Mucoceles are retention cysts of the paranasal sinuses, specially developed on the anterior ethmoid and frontal sinuses and seldom seen on the maxillary cavity, as was the reported case. The authors underline the bone deformities sometimes seen and the difficulties when interpreting the meaning of x-ray records, both circumstances leading, from time to time, to the suspicion of a malignant tumor.

[Jugular phlebectasia].

The seldom seen ectasia of the veins of the neck are known as venous congenital cyst, venous aneurysm, jugular phlebectasia, venous ectasia of the neck or essential venous dilatation. The latter nomination meaning the augmentation of the vessel without either typical histopathologic feature or etiopathogenic explaining its development. All veins of the neck can be affected, especially in this sequence: interna, externa jugular, anterior jugular and the superficial communicans.

[Warthin's tumor and epidermoid carcinoma of the larynx. Apropos of a case].

The general belief is that primitive multiple growths either in the aero-digestive pathways or elsewhere are increasing events. In the paper is presented a clinical case of Carcinoma of the larynx with an homolateral submaxillary lump which was firstly taken as a metastatic adenopathy. At examination both macro- and microscopically show to be a lymphomatous papillary. Cystadenoma (Warthin's tumor). Comments about the sitting of those multiple tumors as well as the features of the Warthin's tumor.

[Melanoma of the hard palate].

Oral melanomas are extremely rare and occur most often on the palate and gingiva. Its prognosis is poor. Surgical management remains the preferred treatment, sometimes in combination with chemotherapy. We report the case of a 72 years old woman with a malignant melanoma of the hard palate who developed three years later a gingival nevi and 5 years later metastatic cervical lymph nodes. Our treatment has been only radical surgery all times.

[Mortality in advanced stage laryngeal cancer].

Patients with advanced laryngeal carcinoma present a high mortality rate due to locoregional recurrence, distant metastases and second cancer. We present a report about the most important prognostic factors in mortality in patients included in III and IV stages. The most important are the presence of metastatic lymph nodes (p = 0.001), extracapsular spread (p = 0.002) and N stage (p = 0.005).

[Interaction between hypertriglyceridemia and noise in human hearing].

We carry out a cross-sectional study on 1205 workers exposed to industrial noise. After the clinical, analytical and audiological examination, we can't demonstrate any influence of hypertriglyceridemia on noise induced hearing loss. We get a statistically significant relationship between noise and hearing loss only in the group of workers with normotriglyceridemia.
