SUBDURAL EFFUSION IN CHRONIC CRYPTOCOCCAL MENINGITIS IN A CIRRHOTIC PATIENT

A case of subdural effusion developing in chronic cryptococcal meningitis in a cirrhotic patient is described - an association not previously reported.     

HLA-B27 associated arthropathies

The association between histo-compatibility antigens and disease is reviewed, in particular that between HLA-B27 and spondylitic disorders, i.e., ankylosing spondylitis, Reiter's arthritis, psoriatic arthritis, and ankylosing hyperostosis. We determined whether the presence of HLA-B27 predicted specific radiographic findings and, conversely, whether specific radiographic changes predicted antigenic status. The prevalences of the HLA-B27 antigen in our patients were: ankylosing spondylitis, 100%; Reiter's arthritis, 93%; psoriatic arthritis, 55%; and ankylosing hyperostosis, 12%. The only specific radiographic finding associated with B27 positivity was severe spondylitis in psoriasis.     

Argyrophilic nucleolar organizer regions (AgNOR) in tumours of pharynx and larynx

Benign and Malignant squamous cell tumours from pharynx and larynx have been studied by silver colloidal staining technique for quantitative analysis of argyrophilic nucleolar organizer regions (AgNOR) per nucleus and to assess its significance in differentiating the benign from malignant tumours. A total of 23 neoplasms including 8 squamous papillomas from larynx, 5 squamous cell cracinomas from larynx and 10 squamous carcinomas from pharynx have been studied. AgNOR count from benign papillomas showed a mean count of 2.56 whereas that in squamous cell carcinoma of Pharynx and larynx was 12.61 and 11.43 respectively. This simple staining method can be used to differentiate benign from malignant tumours in pharynx and larynx.
