[Cervical lymphatic tuberculosis in the 90's: a case report].

The Authors report a clinical case of lymph nodal cervical TBC which led to a retropharyngeal abscess with ossifluent evolution towards the mediastinal region and with fistulation in the dorsal region. A thorough study was carried out on the diffusion of the liquid along the fascial plains of the prevertebral region of the neck and of the mediastinum. With the aid of radiologic tools (CAT scans in particular), and on the basis of topographical anatomy data Authors formulate an hypothesis concerning the mechanics that brought about such a downward development of the abscess. In our opinion this case may well be of interest for otolaryngologists from an epidemic point of view (there is a recrudescence often in atypical manifestations), and because of its surgical peculiarities.

[Laryngeal malignant schwannoma in a 9-year-old boy: report of a clinical case].

A case of malignant schwannoma of the larynx in a 9 year old boy is reported. The lesion recurred 29 months later with the same histological pattern. The malignant peripheral nerve sheath tumours of the larynx are rare and are almost exceptional in paediatric age. The Authors discuss the main differential diagnosis of spindle cell paediatric tumors of the laryngeal region.

[Localized amyloidosis of the larynx].

Localized laryngeal amyloidosis is a rare laryngeal disease which accounts for less than 1% of all benign laryngeal tumors. The symptoms depend on where the amyloid deposit is located in the larynx. When the vocal cords are involved there may be some hoarseness; pain or increasing difficulty in inspiration may arise when, respectively, the aryepiglottic fold or subglottic space are involved. The present paper reports a case of laryngeal amyloidosis without any sign of systemic disease. It also deals with the principle diagnostic procedures to follow. After a review of the literature, emphasis is placed on how important it is to recognize laryngeal amyloidosis in order to achieve an appropriate diagnosis and plan therapy properly. Surgery is the main treatment using either endoscopy or an external neck approach. Recently CO2 laser surgery has been used successfully. Prognosis depends on both the size of the amyloid deposit and whether there is some simultaneous overall involvement.

[Nasal and bronchial respiratory pathology in a group of workers exposed to phthalic anhydride].

Each subject answered a questionnaire, and was submitted to respiratory function tests, bronchial challenge with methacholine and ultrasonic "fog", specific challenge with fumes and powder of PA, measuring nasal and bronchial resistances at the same time by means of a plethysmograph. Serum specific IgE against PA were assessed by the method E.L.I.S.A. Inhalation of "fog" induced a positive nasal response (i.e. nasal resistance increase greater than 70% from baseline) in 73.7% of the subjects, whereas only 3 subjects had a positive bronchial response; specific challenge with PA induced a positive nasal response in 75% out of the subjects, whereas a positive bronchial response was observed in only one subject. 22.7% of the subjects had bronchial hyperreactivity to methacholine. In none of the subjects specific IgE against PA were detectable. We conclude that PA acts as an aspecific irritative agent of airways, particularly of nasal airways.

Airway Resistance

Non-specific nasal reactivity: a proposed method of study.

To test a method for assessing non-specific nasal hyperreactivity, we submitted 23 allergic rhinitis sufferers, 12 normal subjects, 2 patients with asthma and 3 patients with asthma and rhinitis to bronchial challenge with ultrasonic fog (UNDW), recording nasal resistance (NR) and specific bronchial conductance (sGaw) simultaneously by means of a plethysmograph. A significant post-challenge NR increase was observed in 19 of the 23 rhinitis patients, in every patient with asthma and rhinitis, but in only 2 of the 12 normals and in none of the patients with asthma. There was no disturbing increase of nasal secretion. A significant post-challenge sGaw decrease was observed in all the asthmatics and in the patients with asthma and rhinitis, but only in 1 of the 12 normals and in 3 of the 23 rhinitis patients. We conclude that bronchial UNDW could be a suitable method for assessing both nasal and bronchial hyperreactivity.
