The methods of caries removal have been the subject of many studies over the last years. At present, methods involving the least tissue invasion have been outstanding in the field of surgical-restorative treatment. In this context, the Carisolv™ system has appeared as a less traumatic and less invasive approach, particularly in pedodontics. Thus, the objective of the present study was to carry out a comparative analysis of the dentinal structure of primary molars before and after the removal of carious tissue by mechanical (low speed drills and conventional dentinal curettes) and chemomechanical (Carisolv™ kit) procedures based on quantitative culture for cariogenic bacteria to determine the number of bacteria present in the carious dentine after both treatments. Sixty primary molars from children ranging in age from 4 to 8 years, with active occlusal caries in dentine, were divided into two groups (A and B) of 30 teeth each, with group A having been treated by the chemomechanical technique and group B by the mechanical technique. Dentin samples were placed in glass vials containing 1 mL thioglycolate broth and submitted to culture to determine the number of S. mutans and Lactobacillus per mg of decayed dentine. The results did not reveal significant differences between the two methods of caries removal; however, the chemomechanical method was more efficient in completely eliminating S. mutans (p=0.02). In summary, the present results confirm previous studies showing that the two methods are comparable in reducing Lactobacillus, but Carisolv™ is more effective in the elimination of S. mutans.

The study was undertaken aiming at identifying bacteria from the county of Raposa in the state of Maranhão. The clinical sample was collected by using a swab and held in a Cary-Blair transport medium. Enrichment in alkaline peptone water, isolation in TCBS selective indicator medium and biochemical coding of species were used for laboratory processing. Fifty fisherman with age varying from 12-65 years took part on the study. Vibrio bacteria isolated in 21 subjects had been identified. There was a predominance of V. alginolyticus (66.6%) followed by V. parahaemolyticus (42.8%), and V. cholerae non-O1 (9.5%). Lesions predominated on lower limbs, presenting hyperhemia, swelling, secretion, and pain. Some species of gram-negative bacteria of the Serratia, Proteus, Escherichia, Citrobacter, Enterobacter associated to the vibrios were isolated, as well as other non-fermenting bacteria (30.9) and gram-positive bacteria of the genos Staphylococcus.

Background: Music can influence human behavior and may be used as a complementary therapy in health care. Objectives: To assess the effect of music interventions on symptoms, adverse events, and quality of life (QoL) of breast cancer patients undergoing chemotherapy (CT). Design: Nonblinded, randomized clinical trial. Women with breast cancer undergoing adjuvant CT were randomized into 2 groups—Group Music (GM) or Group Control (GC)—and followed during the first 3 cycles of treatment. Measurements: Sociodemographic data, WHOQOL-BREF, BDI-II, BAI, and Chemotherapy Toxicity Scale were assessed. Patients were evaluated after each session of the first 3 CT cycles. GM underwent a 30-minute musical intervention before CT. There was no intervention in the GC. Continuous data were analyzed by Student’s t test, and χ2 test was used to compare qualitative variables. Results: Higher QoL scores on functional scales were observed for the GM in comparison to the GC after the first and third sessions of CT. Depression ( P < .001) and anxiety scores ( P < .001) and vomiting ( P < .01) incidence were lower for the GM in the third session of CT. All the participants in the GM reported positive changes in life in the Subjective Impression of the Subject questionnaire, as well as improvement in fatigue and reduced stress levels. Conclusions: Improvements in QoL, anxiety, depression, and incidence of vomiting were associated with the music intervention, suggesting a positive effect of the music intervention on adverse events of cancer CT.

The bacterial flora from leishmanial ulcers was studied. The aerobic species Staphylococcus aureus and Pseudomonas aeruginosa were found most frequently. Evaluation of the sensitivity of these species to antibiotics showed that 100% of these isolates of Staphylococcus aureus were sensitive to vancomycin, amikacin and chloramphenicol, while 100% of the isolates of Pseudomonas aeruginosa were sensitive to amikacin, gentamicin and tobramycin. These species were generally resistant to penicillins and tetracycline.

Foi investigado, no período de outubro de 1997 a outubro de 1998, a possível associação de Vibrio cholerae com o zooplâncton dos estuários dos rios Anil e Bacanga, em São Luis - MA, Brasil, a presença da forma viável, mas não cultivável de Vibrio cholerae O1 e a correlação entre pH, salinidade e temperatura da água com a sobrevivência da bactéria. Amostras de zooplâncton foram coletadas em dois pontos fixos em cada estuário. O método clássico de isolamento e imunofluorescência direta foram empregados na detecção da bactéria. Nas 52 amostras obtidas de zooplâncton houve predomínio de Copepodes. O cultivo permitiu a obtenção de 55 isolados de Vibrio cholerae não O1. Os sorogrupos O1 e O139 foram demonstrados, respectivamente em 37 (71,1%) e 17 (32,7%) na imunofluorescência. Formas viáveis, mas não cultiváveis de Vibrio cholerae O1 foram detectadas em 70,8% das amostras estudadas. Correlação significativa foi constatada entre salinidade e pH da água e isolamento de Vibrio cholerae.

Background: Extended vertical gastrectomy is a variation of the vertical gastrectomy technique requiring studies to elucidate safety in relation to gastroesophageal reflux. Aim: To analyze comparatively vertical gastrectomy (VG) and extended vertical gastrectomy (EVG) in rats with obesity induced by cafeteria diet in relation to the presence of reflux esophagitis, weight loss and macroscopic changes related to the procedures. Methods: Thirty Wistar rats were randomized into three groups, and after the obesity induction period by means of a 28-day cafeteria diet, underwent a simulated surgery (CG), VG and VGA. The animals were followed up for 28 days in the post-operative period, and after euthanasia, the reflux esophagitis evaluation was histopathologically performed. Weight and macroscopy were the other variables; weight was measured weekly and the macroscopic evaluation was performed during euthanasia. Results: All animals presented some degree of inflammation and the presence of at least one inflammation criterion; however, there was no statistically significant difference in the analysis among the groups. In relation to weight loss, the animals in CG showed a gradual increase during the whole experiment, evolving to super-obesity at the end of the study, while the ones with VG and EVG had weight regain after the first post-operative period; however, a less marked regain compared to CG, both for VG and EVG. Conclusion: There is no difference in relation to reflux esophagitis VG and EVG, as well as macroscopic alterations, and both techniques have the ability to control the evolution of weight during postoperative period in relation to CG.

To compare the satisfaction levels about the surgery and anesthesia management, and to analyze the postoperative outcomes of patients undergoing Gastric Bypass and Sleeve Gastroplasty surgeries in a private hospital in Sao Luís-MA. Methods: The sample consisted of patients undergoing Bypass and Sleeve bariatric surgeries from August 2018 to August 2019, who were in the range of 18 and 70 years old and had not used drugs or presented cardiac arrhythmias, dilated cardiomyopathy, and conduction disorder heart. Data were collected from the evaluation forms and recorded in a form with closed questions. Results: Most patients were female (Bypass-56% and Sleeve-67.4%) and aged between 30 and 39 years old (Bypass-32% and Sleeve-55.8%). Information (Bypass-92% and Sleeve-86.1%) was the highest satisfaction index found. Sleepiness in the immediate postoperative period (Bypass-92% and Sleeve-93%) was the main side effect. There were no postoperative complications in patients between the two types of surgery. Conclusions: Patients submitted to Bypass and Sleeve were completely satisfied with the perioperative management. There was no statistically significant difference when comparing adverse effects between the techniques.
