Aerobic and anaerobic subgingival bacteria were cultured and identified from 49 dogs and 40 cats with spontaneous gingivitis. The most common organisms were gram-negative anaerobes (37% of canine isolates and 39% of feline isolates) and gram-positive aerobes (36% of canine isolates and 29% of feline isolates). No major differences were found between the subgingival floras of dogs and cats with gingivitis.
This paper describes two family members who have a combined hereditary deficiency of factors VII and VIII. The propositus, a 16-year-old male, presented with recurrent gastrointestinal bleeding. He and his mother had moderate defects of factors VII and VIII. The propositus received factor VIII cover, during and after a laparatomy. The possible hereditary transmission pattern of the combined defect is discussed.
The increased risk of thrombosis seen in patients with malignancy also was recently confirmed in breast cancer patients undergoing hormonal or chemotherapeutic treatment. Besides changes within the coagulation system, alterations of hemorheologic variables have been implicated in the genesis of thrombosis. We evaluated plasma viscosity, erythrocyte aggregation, fibrinogen level, sedimentation rate, hematocrit concentration, and protein concentration in patients with breast cancer at the time of primary diagnosis and during follow-up with or without treatment. We then compared the results to a control group without malignant or infectious disease. Plasma viscosity and erythrocyte aggregation were significantly higher in patients with malignant disease, with a further increase at the time of dissemination. Plasma fibrinogen level was significantly higher only at the time of dissemination. The influence of therapy on hemorheologic variables was minor. Tumor volume was the most important factor. As individual values vary considerably and form a continuous spectrum, no cutoff line between normal and pathologic values can be defined. However, high values should induce further measures to diagnose metastatic disease. Second, these factors could explain the relative inefficiency of thrombosis prophylaxis in this patient group and suggest the addition of rheologically active drugs to the treatment regimen.
130 patients with Crohn’s disease were colonoscopied in a multicenter trial. The obtained data were analyzed with respect to gathering information on the inflammation pattern, as well as on the importance and prognostic value of special lesions in Crohn’s colitis. In 52 patients a second endoscopy was performed at the end of the 2-year study period. Ulcerations and aphthous lesions were the most common lesions, followed by pseudopolyps, cobblestone lesions and stenosis. In general, there was an increasing, distal gradient in the frequency of severe lesions. Patients with Crohn’s colitis alone had more signs of inflammation than patients with additional involvement of the small intestine. A segmental pattern was the most common form of inflammation. The group of patients (14%) with a continuous pattern did not deviate from the whole collective in clinical activity. In patients with previous resections, inflammation near the anastomosis was accompanied more often than not by stenosis. Patients with ulcerations had a rather short time since confirmation of the diagnosis. Cobblestone lesions and pseudopolyps correlated with short symptomatology. During the follow-up of the study, patients taking steroids or a combination with prednisolone and sulfasalazine seem to have better results than those under placebo or sulfasalazine alone, as regards the more severe symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
