Rathke's cleft cysts are cystic sellar and suprasellar lesions, characteristically lined by a single layer of ciliated cuboidal or columnar epithelium. In contrast, craniopharyngiomass, which are also cystic sellar and suprasellar lesions, are characteristically lined by stratified squamous epithelium with keratinization on a layer of connective tissue.

OBJECTIVE Meta-iodo-benzyl-guanidine labelled with 131-iodine [(131)I-mIBG] has been used extensively for imaging tumours originating from the neural crest but experience with its therapeutic use is limited, particularly for non-catecholamine secreting tumours. In order to assess the therapeutic response and potential adverse effects of the therapeutic(More)
Menstrual irregularity is common in women with acromegaly, occurring in 40-84%. Although it has been attributed to gonadotropin deficiency and/or PRL excess, it has not been evaluated in detail, and its pathogenesis is not well understood. To explore the various possible pathogenic mechanisms, we have analyzed the clinical, endocrinological, and(More)
OBJECTIVE To investigate whether microalbuminuria is associated with markers of the acute-phase response in NIDDM and whether there are ethnic differences in this association among the three main racial groups in Malaysia.

A growing body of evidence suggests that survival after acute myocardial infarction (AMI) is considerably worse among blacks than whites. The severity of coronary artery disease (CAD), as measured by the number of diseased vessels and the degree of left ventricular dysfunction, is the major determinant of survival after AMI. To determine whether or not the(More)
Differences in cell cation metabolism have been previously demonstrated between blacks and whites in the US. To investigate a potential racial/genetic basis for these differences we studied red cell sodium content (Nai) and platelet cytosolic calcium (Cai) in a group of US whites (n = 26), US blacks (n = 20) and West African blacks (n = 26) residing in(More)
