- A 7-year-old boy with recurrent pneumonia of the right lower lobe is described. At bronchoscopy a small tumour almost totally obliterating the right lower lobe was detected. Surgical treatment was undertaken. Histopathologic studies showed findings consistent with those of a muco-epidermoid tumour. The case emphasizes bronchoscopy as an important investigation in children with recurrent pneumonia. It also shows the importance of performing the bronchoscopy during a prolonged course of antibiotic prophylaxis in order to ensure a minimum of infected mucus within the bronchi. This report is completed with a short review of the literature on muco-epidermoid tumours of the bronchus in children. Their favourable prognosis and very low malignant potential is underlined.

- The influence of different kinds of industrial solvents on the vestibular function of rats has been studied by recording nystagmus, induced by accelerated rotation. The effect was related to the blood levels of the solvents. One group of solvents, including halogenated saturated hydrocarbons like dichloromethane, caused depression of the vestibulo-oculomotor reflex (VOR). Another group, including benzene compounds like xylene, toluene, styrene and cumene and halogenated unsaturated hydrocarbons like trichloroethylene caused an excitation of the VOR. The most striking chemical similarity between the different solvents in the last group is the occurence of double-bonds. If the animals were exposed simultaneously to solvents from both groups the excitatory effect prevailed and was even potentiated. It is suggested that solvents cause depression or excitation of the VOR by interaction with central pathways in the reticular formation and the cerebellum.
