[Facial solitary infantile myofibromatosis]. / Miofibromatosis infantil solitaria de la cara.

Infantile myofibromatosis is an infrequent and benign pathology. It can turn up as a single or multiple tumour. The prognosis depends on visceral involvement. The differential diagnosis includes some pathologies with similar clinical appearance but worse prognosis. We report a 6 months old boy that arrived to our office refering a short progress and fast growth facial mass. The diagnosis after hystologic study and immunohistochemistry was infantile myofibromatosis. After more than a year of monitoring he is actually disease free.

La miofibromatosis infantile es una patología benigna poco frecuente. Puede presentarse en forma de tumor único o múltiple. El pronóstico varía según la afectación visceral. Se debe diferenciar de otras entidades clínicamente similares que presentan peor pronóstico. Presentamos el caso de un varón de 6 meses con una tumoración facial de corta evolución y rápido crecimiento. Fue diagnosticado de miofibromatosis infantil tras estudio histológico de la pieza, confirmado mediante inmunohistoquímica. Tras más de un año de seguimiento el paciente sigue libre de enfermedad

[Importance of laser in the surgical technique of otosclerosis and its results]. / Importancia del láser en la técnica quirúrgica de la otosclerosis y sus resultados.

The authors bring up the matter of the usefulness of laser in otosclerosis surgery. They set out some advantages of laser utilization. A bibliografic review is done and some important authors are found explaining the advantages of this instrument. Some new tendencies on stapes surgery are presented. Teaching on otosclerosis surgery problems are stated, with some different criteria. The idea that improvement of audiologic results in stapes surgery is not easy is strengthened, because the results obtained with the classic techniques are excellent, but some of these methods increase the surgical comfort and reduce the potential risks to the patient.

Importancia del láser en la técnica quirúrgica de la otosclerosis y sus resultados / Importance of laser in the surgical technique of otosclerosis and its results

Los autores plantean la utilización del láser en la cirugía. Se revisa la literatura, en la que se encuentran autores que nos hablan de las ventajas que supone la utilización de este instrumento. También se recogen nuevas tendencias en la cirugía del estribo. Se plantea la enseñanza de la cirugía de la otosclerosis, con diferentes criterios. Se refuerza la idea de que es dificil mejorar los rendimientos auditivos, ya que los que se obtienen con técnicas clásicas son excelentes, pero si que se mejora la comodidad y se disminuyen los riesgos

[Subepithelial glands in the hamster's larynx]. / Estudio de las glándulas subepiteliales en la laringe del hamster.

We have performed, with light microscope, a study about the distribution and morphology of the subepithelial glands of the hamster's larynx. The results are: at the base of the tongue the great deal of the glands are mucous, at the epiglottic base seromucous and at the subglottic space (at the level of cricoid cartilage) serous.

[Histological study of the rat's nasal sinus cavity. Its use in investigation]. / Estudio histológico de la cavidad nasosinusal de la rata. Su utilización en investigación.

An histologic study was performed by light microscopy of the rat nasal cavity. A neuroepithelial lining is found in the backside of the cavity and the medial portion of vomeronasal organ. A respiratory seudostratified epithel with a great deal of submucous glandulae cover the remainder of the cavity.

[Mast cells in the nasal mucosa of patients with nasal polyps. A histological study with lectins]. / Los mastocitos en la mucosa nasal de pacientes con poliposis nasal. Estudio histoquímico con lectinas.

Histochemical studies done with lectins are helpful for differentiate between several carbohydrates and glycoproteins of cell structures. Mast cells predominate in the nasal polyps mucosa of these patients. Cytoplasmic granules of mastocyts reacted to all lectins employed but LTA.

[Differences between excretory ducts of normal submucous glands and those of nasal polyps. A histochemical study with lectins]. / Diferencias entre los conductos excretores de las glándulas submucosas de la mucosa normal y la de los pólipos nasales. Estudio histoquímico con lectinas.

We have performed an histochemical study with lectins of normal nasal mucosa in 6 patients admitted at Hospital because an abdominal pathology, and other 6 with nasal polyps. Results showed a similar reactivity to lectins of excretory duct cells of seromucous glandulae of basement membrane of normal nasal mucosa and the analogous cells of the nasal polyps mucosa.

[Lectin-mediated histochemical study of submucous glands of the normal nasal mucosa]. / Estudio histoquímico mediante lectinas de las glándulas submucosas de la mucosa nasal normal.

We have performed an histochemical study with lectins of the normal nasal mucosa of 6 patients. These patients were admitted at the Hospital for abdominal surgery. A wide biopsy was taken of the inferior nasal turbinate mucosa. The results show a different reactivity between the serous and mucous cells of the submucosal glands and with the goblet cells. We have not found reactivity to DBA, SBA and LTA lectins.

[Histochemical differences between submucosal glands and globet cells of the subglottis. A study in the hamster]. / Diferencias histoquímicas entre las glándulas submucosas y las células caliciformes de la subglotis. Estudio en el hámster.

The differences between the submucosal glands and globet cells of the subglottic mucosa were studied by lectin immunohistochemistry in 4 larynxes of Syrian golden hamster (Mesocricetus auratus). Submucosal glands showed intense reactivity to HPA, N-WGA and N-PNA and reactivity to PNA, UES-I, and ConA, but globet cells showed no reactivity.

[Sudden laryngeal paralysis in a patient with multisystemic atrophy]. / Parálisis laríngea brusca en una paciente con atrofia multisistémica.

A case of acute bilateral vocal cord paralysis in adduction of an elderly woman with multisystem atrophy is reported. Emergency tracheotomy was performed.

[An increase of plasma cells in the regenerated mucous membrane of maxillary sinus. Experimental study]. / Aumento de células plasmáticas en la mucosa regenerada del seno maxilar. Estudio experimental.

In ten albino New Zealand rabbits we studied in the regenerated mucosa of the maxillary sinus what happens after three months of radical removal of sinus mucosa. The study was realized by light and electronic microscopy, with special attention to the plasma cells around the submucosal glands. There is an increased of plasma cells, in a proportion of 10:1.

[The hamster's larynx as an experimental model]. / La laringe del hamster como modelo experimental.

A macroscopic study and with light microscopy as well is performed in the larynx of 4 hamsters. Morphology of hamster's larynx is described. Transitional epithelium is found out on the epiglottis base and caudally to the vocal cords. Hamster's larynx may be a good model for experimental study of changes during carcinogenesis.

A rare case of vascular leiomyoma of the inferior nasal turbinate in a diabetic patient is presented. Local excision was performed under endoscopic control. There have not been signs of recurrence after 2 years follow-up.

Merkel cell carcinoma in the nasal cavity: a case report.

Merkel cell carcinoma is an aggressive dermal neoplasm of neuroendocrine origin with a predilection for the head-and-neck region in elderly patients. We present a case of Merkel cell carcinoma of the nasal fossa. Local wide excision was performed.

Radical or partial maxillary sinus surgery: a dilemma today? An experimental study.

To evaluate partial or radical surgical removal of the maxillary sinus mucosa, 20 New-Zealand albino rabbits were used. After three months, specimens were taken for examination. Bacteriological cultures, light- and electron microscopy were performed, and mucociliary transport was studied. These experimental findings add further support to the concept of performing a conservative sinus procedure rather than a radical removal as a first procedure.

[Basal and non-hair cells in the regenerated mucosa of the maxillary sinus]. / Células basales y no ciliadas en la mucosa regenerada del seno maxilar. Estudio experimental.

In 10 albino New Zealand rabbits, a study was made of the regeneration of the hair cells in the maxillary sinus mucosa three months after removing the sinus mucosa. Using optical microscopy and transmission and scanning electron microscopy, basal and non-hair cells were studied as the probable origin of hair cells. The regenerated sinus mucosa showed areas of epithelium consisting only of a basement membrane and a layer of basal cells. Ultrastructurally, two types of basal cell were visible in the regenerated mucosa. The proportion of non-hair cells was greater than in normal mucosa.
