Saliva contamination by opportunistic microorganisms in drug addiction females

In recent decades there has been a significant increase in the consumption of legal and illegal drugs, and most of such compounds are able to induce dependence and this increase was observed mainly in females. This drug addiction increases susceptibility to several infectious agents, especially opportunistic microorganisms. The objective of this study was to evaluate the occurrence of opportunistic bacteria and yeasts in the mouth of drug addiction patients and non-addicted patients with different periodontal conditions. The study included 50 addiction patients and 200 non-addiction subjects. Intra and extraoral clinical examinations were performed and saliva samples were transferred to saline solution and the presence of members of the family Enterobacteriaceae, genera Enterococcus and Pseudomonas, as well fungi of the genus Candida was evaluated by culture. Samples were cultivated onto selective and non-selective media under aerobic conditions, at 37oC, for 24 -48 h. Identification of selected microorganisms were carried out through biochemical tests. Chi-square test was used to evaluate the data when three or more categories were involved. Higher detection frequencies of Candida species, family Enterobacteriaceae, E. faecalis, Pseudomonas sp. and P. aeruginosa in addiction patients were verified. It was found that patients addicted to both genders showed a higher occurrence of members of the Enterobacteriaceae, which were also associated with bone loss only in patients with drug addiction.

Ocorrência de microrganismos periodontopatogênicos em pacientes com dependência química

Drug addiction won dramatic aspects in terms of its dimensions and the effects that it imposes. These chemical agents are able to reduce the immune reactivity and tissue repair, and enhance microbial aggression, aggravating the destruction of the periodontium and other side effects. This study aimed to evaluate the presence of key periodontal pathogens in the mouth of drug addiction patients, comparing it with individuals who do not exhibit this dependence, as well as assess the influence of oral conditions on the occurrence of such microorganisms. For this purpose, data on systemic health conditions, socioeconomic, patterns of licit or illicit drug consumption of 100 patients with chemical dependency kept in rehabilitation clinics and an equal number of non-dependent patients, who formed the control group were obtained. Intra and extraoral clinical examinations were performed and samples of supragingival and subgingival biofilm, saliva and mucous membranes were collected. The presence of the targeted microorganism was assessed by polymerase chain reaction (PCR). It was found that Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola showed close correlation with bone loss and gingival bleeding in drug addiction dependents and control group, but the oral mucous membranes and saliva of addicts showed higher occurrence of these pathogens.

Análise retrospectiva de 61 casos de paracoccidioidomicose diagnosticados na Faculdade de Odontologia de Araçatuba/ UNESP

Paracoccidioidomycosis is a systemic mycosis which requires prolonged treatment. It is highest prevalence in Latin America, with different endemic areas in Brazil. In this study the aim was to characterize clients suffering from mucocutaneous paracoccidioidomycosis by analysis of histopathological examinations of 61 adult patients diagnosed with mucocutaneous paracoccidioidomycosis treated at the Dental School of Araçatuba, from January 1989 to December 2004. It was observed that the disease occurred in 91.81% (56) men and 8.19% (5) women, more prevalent (78.68%) in whites, aged 40 to 59 years (62.9%) and the profession linked to agriculture in 17 patients (27.86%). All patients had oral manifestations, in multiple sites, but it was most prevalent in the oral mucosa (31.42%) and alveolar ridge (17.14%). The dentist as an integral member of the health services, must know the clinical manifestations of paracoccidioidomycosis to achieve early diagnosis and thereby to improve the quality of life of patients.

Use of power doppler for the assessment of vascularization in equine tendinitis treated with mesenchymal stem cells

Tendinous lesions are very common in athlete horses. The process of tendon healing is slow and the quality of the new tissue is often inferior to the original, leading in many cases to recurrence of the lesion. One of the main reasons for the limited healing capacity of tendons is its poor vascularization. At present, cell therapy is used in equine practice for the treatment of several disorders including tendinitis, desmitis and joint disease. However, there is little information regarding the mechanisms of action of these cells during tissue repair. It is known that Mesenchymal Stem Cells (MSCs) release several growth factors at the site of implantation, some of which promote angiogenesis. Comparison of blood flow using power Doppler ultrasonography was performed after the induction superficial digital flexor tendon tendinitis and implantation of adipose tissue-derived MSCs in order to analyze the effect of cell therapy on tendon neovascularization. For quantification of blood vessel histopathological examinations were conducted. Increased blood flow and number of vessels was observed in treated tendons up to 30 days after cell implantation, suggesting promotion of angiogenesis by the cell therapy.

Isolamento e identificação das micobactérias em águas tratadas provenientes do sistema de abastecimento de Araraquara-SP

Water quality is very important for the health and the population welfare, and the public supply system must provide water quality and suffi cient quantity for the entire population. Water treatment stations, are the main way to obtain water quality. When this doesn’t occur, several problems can affect the population, in this case, using water with poor quality is a constant risk of emergence causing various diseases. The elimination of microorganisms in treated water reduces competition, encouraging the multiplication of chlorine resistant bacteria as Mycobacterium genus frequently isolated from treated and chlorinated water. Considering the lack of indication from examinations of mycobacteria routine laboratory for quality control of drinking water and other human uses, the objective was to verify the presence isolate and identify the environmental mycobacteria in the system water source surface of Araraquara - SP. We analyzed 40 water samples, distributed as follows: ten water gross collected at Station Water Treatment Plant (WTP), harvested after ten fi ltration; ten collected in the reservoir after chlorination and ten in the network distribution. Were recovered 43 isolates of mycobacteria. All isolates were subjected to PCR-PRA. The mycobacteria were identifi ed as M. lentifl avum, M. parafortuitum, M. genavense, M. gordonae, M. fortuitum, M. confl uent, M. duvalii, M. avium subspecies paratuberculosis and M. szulgai. With these results, was concluded that water is an important source of environmental mycobacteria probably related to several human diseases, suggesting the carrying out continuous monitoring of the microorganisms in the system drinking water.

Oral focal mucinosis: clinical case presentation with a focus on aesthetic and functional surgical resolution

Introduction: When planning excisional surgery, alterations in the oral mucosa, particularly in esthetically important areas, represent a challenge. For cases involving an exophytic lesion with a vegetative tumoral aspect, a clinician may prioritize obtaining a definitive diagnosis by histopathologic and histochemical examinations over the preservation of esthetics or maintenance of the involved tooth. Case Presentation: A painless, hard lesion with normal coloration was present in the maxillary left central incisor of a patient for at least 6 years. A biopsy was performed to preserve oral mucosa and a treatment plan was established that included endodontic retreatment and prosthetic restoration. The histopathologic diagnosis was oral focal mucinosis, an uncommon and poorly characterized type of lesion. Conclusion: A conservative biopsy of the lesion facilitated an accurate diagnosis, promoted the patient’s comfort, and achieved satisfactory esthetic results.

Predicting vasospasm after aneurismal subarachnoid hemorrhage with C reactive protein levels

Aim: The interest of inflammatory marker increased in the last years, even in preventing clinical outcome after subarachnoid hemorrhage (SAH). Our objective was to study the relationships between C-reactive protein levels and clinical outcome and the development of cerebral vasospasm after aneurismal SAH. Methods: One hundred adult patients with aneurismal SAH were prospectively evaluated. Glasgow Coma Scale (GCS) score, Hunt and Hess grade, Fisher grade, CT scans, digital subtraction angiography studies, transcranial doppler (TCD) and daily neurological examinations were recorded. Serial serum CRP measurements were obtained on daily between admission and 10th days. Glasgow Outcome Scale (GOS) and the modified Rankin Scale (mRS) were used to predict outcome. Results: A progressive increase in the CRP levels from the admission to the 3rd postictal day was observed, followed by a slow decrease until the 9th day. Hemodynamic changes in TCD were associated with higher serum CRP levels. Patients with lower GCS scores presented with increased CRP levels. Patients with higher Hunt and Hess grades on admission developed significantly higher CRP serum levels. Patients with higher admission Fisher grades showed increased levels of CRP. A statistically significant inverse correlation was established in our series between CRP serum levels and GOS and mRS scores on discharge and CRP levels. Conclusion: Increased CRP levels were strongly associated with poor clinical outcome. CRP levels can predict cerebral vasospasm and delayed ischemic deficits with higher statistic significance. There are relationships between hemodynamic chances in TCD and higher CRP levels.

PS-042c is low-dose combined oral contraceptives use associated to lower bone mineral content variation in adolescents over a one-year period?

Background Low dose combined oral contraceptives (COC) can interfere in bone mass acquisition during adolescence. To evaluate bone mineral density (BMD) and bone mineral content (BMC) in female adolescents taking a standard low-dose (EE 20 µg/Desogestrel 150 µg) combination oral contraceptive (COC) over a one-year period and compare with healthy adolescents from the same age group not taking COCs.Methods A non-randomised parallel control study with one-year follow-up. Sixty-seven adolescents from 12 to 20 years of age, divided into COC users (n = 41) taking 20 µg EE/150 µg Desogestrel and non-user controls (n = 26), were evaluated through bone densitometry examinations at baseline and 12 months later. Comparisons between groups at study start was done through the Mann-Whitney test with significance level fixed at 5% or corresponding p value; comparisons between groups at study start and 12 months later used variations in median percentages for bone mass variables.Results COC users presented low bone mass acquisition in the lumbar spine and BMD and BMC median variations between baseline and at 12 months of 2.07% and +1.57% respectively whereas the control group presented variations of +12.16% and +16.84% for BMD and BMC, respectively, over the same period. The total body BMD and BMC presented similar evolution during the study in both groups. Statistical significance (pConclusion The use of a low COC dose (EE 20 µg/Desogestrel 150 µg) was associated to lower bone mass acquisition in adolescents during the study period.Trial registration: (Register Number):RBR-5 h9b3c

Splenic congestion associated with acepromazine administration in dogs

The effects splenic dilatation induced by acepromazine in a prospective, randomized study. Thirtythree adult mongrel dogs were divided into two groups designated as AG (acepromazine 0.05 mg/kg, i.v., n = 23) and CG (0.9% sodium chloride administered at a similar volume, n = 10). In both groups underwent sonographic examinations before (T0) and fifteen minutes (T15) after drug injection. The thickness spleen and splenic vein width were measured. Higher thickness was found in the AG group at T15 (2.47 cm) when compared to that at T0 (2.06 cm, p = 0.016), while the T0 (2.33 cm) and T15 (2.39 cm) measures did not differ within the CG group. Moreover, the splenic vein width was higher (p = 0.013) at T15 than at T0 in the AG group. Based on results of this study, we concluded that acepromazine, in doses of 0.05 mg/kg, promotes splenomegaly in dogs after fifteen minutes of the injection.
