RESUMO
One hundred consecutive patients with perennial rhinitis were examined clinically and by means of a test battery of laboratory investigations in order to clarify the pathogenesis of the disease, and the clinical value of various tests in the assessment of the patients. In 54% of the cases allergy was proven. The most common allergen was Bermuda grass which is found widely distributed in the Eastern Province. In 46% of the cases, allergy could not be demonstrated. Twelve percent had eosinophilic rhinitis. In this study, investigations of blood eosinophils and IgE were found to be of value in the assessment of patients with perennial rhinitis. The possible connection between pollen allergy and perennial rhinitis in Saudi Arabia is discussed.

Investigations on indoor airborne allergens in Saudi Arabia were performed by mold cultures and dust analyses by counter-current immunoelectrophoresis. Twenty fungal genera were isolated, with Aspergillus as the most often encountered. Most of the dust-bound fungi found are ubiquitous and common. Antibodies against Dermatophagoides pteronyssinus, cat- cow- and rat dander, and Cynodon dactylon pollen were used in the dust analyses. Animal antigens were found in five of the ten dust samples. House dust mites were extraordinarily rare. Pollen of Cynodon dactylon (Bermuda grass) was present in nearly all the samples, and in a concurrent clinical study this antigen was found to be the most common cause of perennial rhinitis.

Progression of dysphagia after vagotomy to the stage of complete obstruction due to a peri-oesophageal fibrotic collar needing operation is a rare event. Review of the 4 such cases previously described, all needing further operation and all after truncal vagotomy, indicates that the oesophageal mucosa was normal on oesophagoscopy and that bouginage appeared to make the condition worse. This paper describes the first patient in whom (a) the vagotomy was selective and (b) no bouginage was carried out before the condition was relieved by a further surgical operation.
