PDT with the diode laser system seems to be effective in reducing malignant bile duct stenosis. This treatment is minimally invasive and has a low specific complication rate. Randomized, controlled studies comparing PDT with the insertion of endoprostheses and long term follow-up of results are needed to confirm the promising short term results.
We report 1 patient with a necrolytic migratory erythema, a high plasma glucagon concentration and a metastatic pancreatic endocrine tumor who has now been treated effectively for 33 months with the somatostatin analogue octreotide (SMS 201–995) (400 μg/day). The results of SMS 201–995 in the treatment of glucagonoma syndrome are reviewed.
Twenty-one rejected kidneys from 2426 slaughtered dairy cows (0.87 per cent) had gross signs of pyelonephritis that were confirmed by histopathology. In all the kidneys the findings were consistent with a chronic rather than an acute infection. One species of bacteria was cultured from 12 of the kidneys and two species of bacteria were cultured from six. The most commonly isolated bacteria were Escherichia coli, from eight kidneys, Arcanobacterium pyogenes, from seven kidneys and Corynebacterium renale, from five kidneys. The other bacteria cultured were Corynebacterium cystitidis, Corynebacterium species, Streptococcus species group G and Enterococcus faecalis. E. coli was cultured from all the kidneys from which two species were isolated; the accompanying bacteria were A. pyogenes in three kidneys, C. renale in two and C. cystitidis in one. No bacteria were cultured from two of the kidneys and no significant bacteria were cultured from another. The kidneys with pyelonephritis were slightly larger than a comparison group of 72 kidneys without nephritis.
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.
