Interstitial cystitis (IC) is characterised by recurrent inflammation and destruction of bladder tissue without obvious cause. To determine whether this self-perpetuating disease is the result of an autoimmune disorder, we studied 26 patients with IC of mean duration 5 years and compared the results with those of a control group of similar age and sex with other urological complaints. We performed a standard autoimmune profile and looked for specific antibodies to normal human bladder in the serum, using an indirect immunofluorescence technique. Deep bladder biopsies were examined by conventional histology and cryostat sections were studied with peroxidase-conjugated anti-human antibodies in a search for immunoglobulin deposition within the bladder. Seventeen of 26 patients with IC (65%) and 5 of 14 controls (36%) demonstrated non-organ-specific antibodies; 40% of those with IC had anti-nuclear antibodies; 18 IC patients (75%) and 4 of 10 controls (40%) had anti-bladder antibodies present in the serum, but 5 healthy volunteers showed no such antibody activity. There was no statistically significant difference between the two groups for either type of antibody (Fisher's exact test). Only 5 of 17 patients with IC (29%) showed immunoglobulin deposition in the bladder epithelium, a similar proportion to controls (38%); 4 of these 5 had circulating anti-bladder antibodies present in the serum. Although IC patients demonstrated a non-specific increase in antibody formation, this was not significantly different from a similar group of other urological patients. The lack of specificity makes this immunological response more likely to be a secondary phenomenon associated with inflammatory damage to the bladder rather than the primary cause of the disease.
A B S T R A C T BACKGROUNDAcute leukemia is characterized by the progressive excessive production of leukocytes in the bone marrow as well as the arrival of immature cells into the peripheral blood. The present study aimed to evaluate the oral hygiene status in patients with acute leukemia. METHODSThe present study included 50 ALL patients referred to the affiliated oncology centers of Kerman University of Medical Sciences from April to December 2015 and 52 healthy children. Data collected from the oral examination included the DMFT/dmft and plaque indexes and the presence of mucositis. Information about the diseases, blood test results, the patients' age, and the type of drug was obtained from medical records. Data was analysed through SPSS software, T-test and Mann-Whitney test at a significance level of 0.05. RESULTSGrade 1 and 2 mucositis was observed in 6 (0.12%) and 1 (0.2%) patients respectively. The plaque index was significantly higher in patients than the healthy group (p= 0.033). The average missing teeth was higher in the ALL group, but it was not statistically significant. There were no statistically significant differences between the individuals with mucositis and those without mucositis (p=0.503). There were no statistically significant differences between the patients and healthy group in terms of the mean DMFT/dmft index. CONCLUSIONSThere were no statistically significant differences between the patients and healthy group in DMFT/dmft index. Statistically significant differences were seen between patients and healthy groups in terms of OHI-S index.
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.
