The external ear and the tympanic membrane. A three-dimensional study.

The study of the anatomical variations of the external ear is important for the ear surgeon who assesses the middle ear in this way. Furthermore, the design of insert earmoulds for use with either hearing aids or portable radios requires a better knowledge of the shape of the external ear. We studied the external ear structures and the drumhead in 140 cadavers with no previous history of ear pathology. A silicone resin was used, employing a dental impression technique. These permanent impressions were analysed by means of an operating microscope. Different parameters were studied, to determine the average dimensions of the structures. The clinical significance of these results is discussed.

Monomorphic adenomas of the major salivary glands: clinicopathological study of 44 cases.

We report 44 cases of monomorphic adenoma (MA) of the major salivary glands observed during the years 1979-1989. All of these tumours were reviewed and classified on the basis of the World Health Organisation (WHO) criteria. Histological type, site, sex and age were considered. 34 cases of adenolymphoma were observed, all of them located in the parotid glands; 10 MA without lymphoid stroma were located in both parotid and submandibular glands. Distinctive histological and clinico-pathological features of the latter group of tumours are discussed, as well as the diagnostic criteria in distinguishing these tumours from pleomorphic adenoma and adenoid-cystic carcinoma.

A double-blind group comparative study of nedocromil sodium in the treatment of seasonal allergic rhinitis.

Thirty-eight patients with seasonal rhinitis due to grass pollen allergy took part in this double-blind study comparing 1% nedocromil sodium and placebo. Treatment was allocated by randomised coding sheet and consisted of 1% nedocromil sodium nasal spray or placebo given four times daily for four weeks during the peak pollen season. Highly significant (p less than 0.001) differences in favour of nedocromil sodium were seen for all signs and symptoms recorded at clinical assessments, and for diary card assessments of symptoms. In addition, time to effect and patient and clinician opinions of treatment significantly (p less than 0.001) favoured nedocromil sodium. Laboratory data on blood and urine samples taken before and after treatment showed no significant effects, and both treatments were well tolerated. Nedocromil sodium 1% nasal spray taken four times daily was shown to be an effective treatment for grass pollen rhinitis.

Serum immunoglobulins and secretory IgA deficiency in tonsillectomized children.

We studied serum immunoglobulin patterns in 65 children aged 2 to 10 years before and 1 to 4 months after tonsillectomy and adenoidectomy, and secretory IgA (sIgA) levels in 46 children aged 3 to 10 years before and 1 month after the same operation. Serum immunoglobulin and sIgA values were normal prior to surgery, and significantly lower afterwards. The data emphasize the importance of palatine tonsils not only in the synthesis of monomeric immunoglobulins but also in the synthesis of dimeric immunoglobulins in secretions. Although more long-term, follow-up studies supporting our results are needed, we suggest that a post-adenotonsillectomy drop in immunoglobulin and sIgA levels may predispose children to a constellation of disorders. We recommend, therefore, that serum immunoglobulins and sIgA levels be determined in all children before and after surgery.

Seven hereditary syndromes with pigmentary retinopathy. A review and differential diagnosis.

This article reviews several autosomal recessive syndromes characterized by pigmentary retinopathy and, in many, combined with deafness, hypogonadism, and/or mental retardation. These syndromes are manifested in infancy and childhood. Although no specific treatment is available, an early diagnosis can be the first step in initiating symptomative management and preventive measures for the patient and family.

Allergy: a leading role in otitis media with effusion.

We have studied 35 children with seasonal allergic rhinitis confirmed by positive skin tests and RAST to grass pollen. Intranasal antigen provocation was performed to evaluate the function of the eustachian tube (ET) and middle ear pressure (MEP). Tympanometry was used to evaluate the changes in MEP, while Valsava and Toynbee tympanometric tests were employed to study the ET function, and the changes in nasal airway resistance were measured by anterior rhinomanometry. ET dysfunction (ETD) and a decrease in MEP and nasal airway resistance were demonstrated in the children under study as compared with the controls. The results suggest a role for allergy in ETD and for the development of OME.
