Histology of nasal polyps of different etiology.

The aim of the present study is to elucidate the correlation between etiology and histology in nasal polyps with special regard to cystic fibrosis (CF). Nasal polyps from 15 children with CF and a control group of non-CF polyps from 15 adult patients were examined by light-microscopy. The histological evaluation was carried out on a blind basis in order to avoid bias. Among the parameters used, the tissue eosinophilia proved to be the most valuable factor in the differentiation between CF and non-CF polyps, as only few eosinophils were found in the CF-polyps. The polyp glands were few and generally pathological. Some characteristics abnormalities in the grandular morphology are apparently more common in CF polyps. It is concluded, that the histological examination of nasal polyps is of importance for the correct classification of the patient, but the diagnosis of CF cannot be made based on microscopy of polyps. Further studies including blinded histological examination of nasal polypous tissue might contribute to a more differentiated diagnose of nasal polyposis.

Bacteriology and antibiotics in acute suppurative otitis media.

One hundred and forty-seven patients with acute suppurative otitis media, were divided into three groups and treated with antibiotics (azidocillin, ampicillin, and cephalexin). The therapeutic effect was assessed bacterioloically by swabbing from the aural discharge and from the nasopharynx on the first, second, third, and seventh day after initiation of treatment. In addition, the concentration of antibiotic in the aural discharge and in the nasopharynx was determined. As compared with other published materials, there was a common occurrence of Haemophilus influenzae and S. Aureus. Hemolytic streptococci are less common than prior to the advent of antibiotics. Pneumococci disappeared in all cases from the aural discharge in the course of the first three days. The effect upon Haemophilus was slower. In the nasopharynx the effect was questionable, and no effect was obtained upon other bacteria. The clinical course could not be correlated to the bacterial findings except that resistant bacteria were found in all cases with persisting discharge.

Replica cytology in cancer of the larynx: an evaluation of a replica method in the diagnosis of laryngeal malignancy.

A series of 38 cytological samples from the larynx, obtained with a replica method, is presented. The method is described in detail. Conclusive material was obtained in 34 cases. Fourteen per cent false negative evaluations were found. However, when more strict criteria were used for accepting the cytological specimen as suitable for evaluation, no false negative was encountered. It is therefore concluded that this replica method for obtaining cytological samples from the larynx could become a valuable tool as a screening method during indirect laryngoscopy in search of laryngeal malignancy provided very strict criteria are used for accepting the cytological specimen as suitable for evaluation.

Association between the C3F gene and atherosclerotic vascular diseases.

The C3 phenotype distribution was studied in a group of patients suffering from atherosclerotic vascular diseases. A statistically significant association was found between the presence of the C3F gene and the occurrence of atherosclerosis. A relative risk incidence of the disease of 1.87 was found for the C3F-positive individuals as compared to the C3F-negative ones.

C3 polymorphism in relation to age.

The C3 phenotype distribution was investigated in different age-groups among 2,078 voluntary blood donors between the ages of 20 and 65 years, in a group of unrelated babies and in a group of old healthy persons. A continuous increase in the C3F gene frequency with age was found among the blood donors varying from 0.1780 in the youngest age group (babies: 0.1585) to 0.2516 at the age of 50-55 years followed by a continuous decrease to a level of 0.1700 among the eldest donors (01718 among the old persons). In the age group 45-49 years the C3 distribution differed significantly from that in the adjoining age-groups (C3F = 0.1619). It is believed that the variations are brought about by selection of the blood donor population and a balanced polymorphism for the C3 system, possibly due to differences in the biological efficiency of the C3 variants in the complement sequence.
