[Pharmacological prophylaxis of gastroesophageal reflux. Incidence of pharyngocutaneous fistula after total laryngectomy].

Pharyngocutaneous fistula is a serious complication of total laryngectomy. This problem increases morbidity, prolongs hospitalization, and occasionally causes death. Numerous contributing factors have been implicated in fistula formation (1). We propose that gastroesophageal reflux, which often is subclinical, is an important trigger and should be prevented. We evaluated the effect of associating an antireflux agent like metoclopramide hydrochloride to our usual ranitidine of our protocol after total laryngectomy on reducing the incidence (p<0.05) of pharyngocutaneous fistula.

[Deep infections of the neck].

Infections of aponeurotic sheets of the neck are more frequent in men than in women. Its etiology although varied is basically related to infectious pharyngo-tonsillar and dental pathology. In a great deal of cases there are factors which predispose clinical manifestations or becoming complications. Early diagnosis and precocious specific treatment re-establish the normality in the majority of cases but a percentage of them resort to surgery for the condition's control.

[Percutaneous gastrostomy under fluoroscopic guidance. A one year experience].

The nasogastric tube has traditionally been used as nutritional support for patients with head and neck cancers. We propose the percutaneous gastrostomy under fluoroscopic guidance as a part of therapy in selected patients with head and neck cancers, or in those who have chronic aspiration and dysphagia secondary to neurologic impairment. Our one-year experience with our series of nasogastric tube is reviewed.

[Leishmaniasis and ENT].

Three cases of the infrequent mucocutaneous Leishmaniasis, with nasal involvement in two of them and affection of the hypophrarynx and larynx in the other one are presented. We remark, in the case with laryngeal disease, that it was the onset of an AIDS in a patient unknown to be HIV+. Leishmaniasis of the larynx has not been described before as the onset of an AIDS. Symptomatology, evolution and treatment of this disease are revised, pointing out the increasing association, in our country, between leishmaniasis and AIDS, and considering the possibility of including the leishmania infection as an AIDS criteria in HIV+ patients, and to rule out an IVH infection in a patient with an atypical leishmaniasis either for the site involved or the evolutive course of the disease.

[Effectiveness of external nasal dilators in nasal ventilatory obstruction. Objective improvement or placebo effect?].

External nasal dilators have become popular among athletes and the general public. When applied to the nares, the device theoretically increases the nasal valve area and decreases total airway resistance. There are doubts regarding the true benefits of this device as opposed to a possible placebo effect. In order to resolve this question, the subjective sensation was compared with an objective measurement in two different groups: a group of 20 persons who complained of nasal insufficiency and a group of 20 control subjects. Computer rhinometry was used for objective measurements and psychological parameters were evaluated with a questionnaire.
