Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It is known for its great disfiguring capacity and is considered an extremely serious disease to public health worldwide. The state of Ceará ranks 13th in number of cases of leprosy in Brazil, and fourth in Northeastern region, with an average of 2,149 new cases diagnosed every year. This study aimed to evaluate the knowledge of leprosy patients regarding treatment, and to assess the level of treatment adherence and its possible barriers. The study was conducted in the reference center for dermatology, from September 2010 to October 2010, in Fortaleza, Ceará. The study data were collected by means of a structured interview, along with the Morisky-Green test, in order to assess treatment adherence and barriers to adherence. A total of 70 patients were interviewed, out of whom 66 were new cases. The majority of patients were between 42 and 50 years old, and 37 (52.9%) were male. Most patients were clinically classified as presentingmultibacillary leprosy (80%), and 78.6% of them were from Fortaleza, Brazil. The Morisky-Green test indicated that 62.9% of patients presented a low level of adherence (p < 0.005), despite claiming to aware of the disease risks. However, it was observed that 57.1% of the patients had no difficulty adhering to treatment, while 38.6% reported little difficulty. This study shows that despite the patients claiming to be familiar with leprosy and its treatment, the Morisky-Green test clearly demonstrated that they actually were not aware of the principles of therapy, which is evidenced by the low degree of treatment adherence

The aim of this study was determine the prevalence and antimicrobial susceptibility of Staphylococcus spp. from patients with periodontal disease and periodontally healthy, correlate them with factors to host, local environment and traits of the diseases. To this, thirty adults from 19 to 55 years old were selected. They had not periodontal treatment and no antibiotic or antimicrobial was administered during three previous months. From these individuals, sites periodontally healthy, with chronic gingivitis and/or periodontitis were analyzed. Eighteen subgingival dental biofilm samples were collected through sterile paper points being six from each tooth randomly selected, representing conditions mentioned. They were transported to Oral Microbiology laboratory, plated onto Mannitol Salt Agar (MSA) and incubated at 370C in air for 48 h. Staphylococcus spp. were identified by colonial morphology, Gram stain, catalase reaction, susceptibility to bacitracin and coagulase activity. After identification, strains were submitted to the antibiotic susceptibility test with 12 antimicrobials, based on Kirby-Bauer technique. To establish the relation between coagulase-negative Staphylococcus (CSN) presence and their infection levels and host factors, local environment and traits of diseases were used Chi-square, Mann-Whitney and Kruskal-Wallis tests to a confidence level of 95%. 86,7% subjects harbored CSN in 11,7% periodontal sites. These prevalence were 12,1% in healthy sites, 11,7% in chronic gingivitis, 13,5% in slight chronic periodontitis, 6,75% in moderate chronic periodontitis and in sites with advance chronic periodontitis was not isolated CSN, without difference among them (p = 0,672). There was no significant difference to presence and infection levels of CSN as related to host factors, local environm ent and traits of the diseases. Amongst the 74 samples of CSN isolated, the biggest resistance was observed to penicillin (55,4%), erythromycin (32,4%), tetracycline (12,16%) and clindamycin (9,4%). 5,3% of the isolates were resistant to oxacilin and methicillin. No resistance was observed to ciprofloxacin, rifampicin and vancomycin. It was concluded that staphylococci are found in low numbers in healthy or sick periodontal sites in a similar ratio. However, a trend was observed to a reduction in staphylococci occurrence toward more advanced stages of the disease. This low prevalence was not related to any variables analyzed. Susceptibility profile to antibiotics demonstrates a raised resistance to penicillin and a low one to methicillin. To erythromycin, tetracycline and clindamycin was observed a significant resistance
