G. Abstract: The measurement of serum of urinary hCG is commonly used to make or exclude the diagnosis of ectopic pregnancy in women presenting with symptoms suspicious of ectopic pregnancy. Detection of depressed hCG levels is indicative of early pregnancy failure. Depressed serum levels of proteins of hormone of trophoblastic, ovarian or endometrial origin make the diagnosis of ectopic gestation more likely, whilst high values are likely to exclude the possibility of this condition.

These tumours, rare in the nose, are believed to be similar to fibrous mesotheliomas of the pleural cavity. The main presenting symptom is that of unilateral nasal obstruction and diagnosis is made on histological examination of the lesion. These tumours have to be distinguished from other spindle-cell tumours of the nasal cavity and sinuses.

Abstract: In none of the spondyloarthropathies is the pathogenesis well understood. Much of the investigation into the aetio-pathogenesis of these diseases has focused on the association with HLA-B27 and the known triggering potential of certain infectious agents. In this article the author describes that the HLA linked genes which is subdivided into three groups, class I, class II and class III, which are structurally and functionally distinct from each other.

Abstract: The seronegative spondyloarthropathies comprise a group of non-rheumatoid disorders with similar clinical, laboratory and genetic features. Recognition of new clinical features has supported the notion that they all form part of a clinical spectrum. These features and the classification of the seronegative spondyloarthropathies are discussed in the review.
