OBJECTIVE To evaluate the significance of serum matrix metalloproteinase-3 (MMP-3) levels in relation to the development of radiological damage (X-ray damage) in early rheumatoid arthritis (RA). METHODS Serum MMP-3 levels were measured in 46 healthy controls (CTRL), 19 osteoarthritis (OA) and 78 RA patients with joint symptoms for <1 yr at presentation(More)
The authors conducted a detailed review of studies on the association between prostate cancer and total dietary fat along with specific fatty acids. Overall, the 29 studies reporting actual dietary fat levels in grams of fat were heterogeneous, suggesting that pooling of the relative risks may be inappropriate. Heterogeneity was also seen by study design.(More)
A serologic survey of anti-Brucella spp. antibodies was undertaken on 2,470 samples of 14 North American marine mammal species collected between 1984-97. Serum or blood from eight species of cetaceans and six species of pinnipeds was sampled from Pacific, Atlantic, and Arctic oceans. Two competitive enzyme-linked immunosorbent assays (C-ELISA's), using(More)
A longitudinal serologic survey was conducted for morbillivirus antibodies in Atlantic walruses (Odobenus rosmarus rosmarus), narwhal (Monodon monoceros), and beluga (Delphinapterus leucas) from the Northwest Territories, Nunavut and the St. Lawrence estuary (Canada). Sixty-five of 131 (50%) walruses sampled between 1984 and 1993 had detectable(More)
Genetic linkage studies are reported on two families with cleft lip +/- cleft palate. For the first family (LP01) the etiology of the clefting is unknown, and the linkage analyses were done assuming both autosomal dominant and autosomal recessive inheritance. Close linkage is rejected with the Duffy blood group under the dominant model and with four loci(More)
A family report of three generations of Van der Woude syndrome (cleft lip or palate and lip pits) is presented to show that the speech-language pathologist may play an important role in identifying patients with this defect. Understanding the genetic basis of this syndrome and documentation of family history through pedigree analysis can be instrumental in(More)
A detailed examination of a stillborn fetus with Apert's syndrome showed several unexpected findings, which prompted a reevaluation of the heretofore generally accepted hypotheses regarding the cause of the dysmorphic craniofacial features in this syndrome. (1) The characteristic clinical features of Apert's syndrome were present at 24 to 26 weeks of(More)
Hypertelorism and hypospadias are described in four unrelated boys; bilateral cleft lip and cleft palate were also present in two of the boys and mild mental retardation in another. These features are compatible with both the G and BBB syndromes. When present, laryngotracheoesophageal anomalies or respiratory and swallowing difficulties are characteristic(More)
Six cases have been presented with combined limb deficiencies and cranial nerve dysfunctions. The major features are congenital disarticulation and congenital amputation associated with various orofacial deficits. Anatomic variations in limb and facial anomalies in these cases, as well as in other cases previously reported; seem to indicate that they are(More)
