Reabilitação estética por meio de prótese ocular a base de PMMA: relato de caso

Eye loss results on facial asymmetry compromising its aesthetics. Ocular prostheses are important to re-establish aesthetics; protect the anophthalmic cavity; recover function such as the redirection of lachrymatory liquid; and reintegrate the patient to society. The aim of this study was to describe a case report, demonstrating clinical and laboratorial procedures for confection of ocular prostheses and highlighting their advantages. A female patient was afflicted by toxoplasmosis, which led to the loss of her eye. An eye visceration was performed. The patient reported no previous use of ocular prosthesis. A PMMA ocular prosthesis was manufactured restoring patient’s aesthetic and facial contour. The patient was satisfied with the treatment. Therefore the present study has shown that PMMA ocular prosthesis is able to restore facial aesthetics and can be a safe and satisfactory alternative for patients that have lost their eyes due to toxoplasmosis.

Susceptibility of microorganisms isolated from necrotic pulps to calcium hydroxide

Calcium hydroxide has been used as pulp-capping agent and canal dressing due to its antimicrobial and anti-inflammatory properties besides its ability to induce formation of mineralized tissues. The aim of this study was to evaluate the susceptibility to calcium hydroxide of 146 bacterial strains isolated from endodontic infections. MIC was determined by using an agar dilution method, while contact bactericide activity was performed through in broth. All the isolates were sensitive to calcium hydroxide in concentrations that varied from 0.5mg/ml to 128 mg/ml, and the genera Enterococcus, Pseudomonas, Staphylococcus and Actinomyces were the most resistant. Gramnegative anaerobes proved to be the most sensitive isolates. All the isolates were inhibited after 60 minutes of contact with the alkali in concentration of 100mg/ml

Chronic osteomyelitis of the maxilla and mandible: microbiological and clinical aspects

Osteomyelitis of the mandible and maxilla are common in developing countries and their treatment may be long-standing and difficult. Thus, the aim of this study was to discuss the main biological aspects of the chronic osteomyelitis of the jaws of especial interest for dental team. These infections are associated with a complex microbiota composed mainly by anaerobic bacteria, sometimes associated with microorganisms originated from the skin and digestive tract. These data suggest that chronic osteomyelitis of the mandible and maxilla should be treated as anaerobic infections in most cases. In addition, local surgical treatments are relevant in the therapy outcome, associated to the use of antimicrobial agents, and the failure to accomplish them is a major cause of treatment failure.

Biossegurança na clínica de radiologia odontológica

In the practice of dental radiology, although there was no production of aerosols, there is the contamination of equipment and surfaces by contact with blood and saliva. This is making necessary the adoption infection control procedures to protect patients and staff. The objective of this paper is to present the procedures of prevention during the radiographic examination and radiographic processing in the darkroom. The proposed recommendations for the area of Dental Radiology include efficient cleaning and protection of equipment and surfaces, personal protective measures and to avoid contamination of the darkroom. These recommendations are obtained by simple procedures as cover films and radiological equipment with plastic barriers.

Manifestación bucal de paracoccidiodomicosis asociada a aspergilosis: presentación de caso

Paracoccidioidomycosis and aspergillosis are, respectively, mycosis caused by Paracoccidioides brasiliensis and Aspergillus fumigatus fungi, which, most frequently, attack the lungs and later spread to other body regions. The association between both mycosis is rare in patients that do not present immunosuppression. A 49-year-old man presented with oral lesion, besides lesions on palatum, retromolar and oropharyngeal regions. Histopathological and microbiological exams confirmed the diagnosis of paracoccidioidomycosis associated to aspergillosis. Historically, fungi have been considered as the cause of relatively important infections, but, in the last years, a significant increase of diseases caused by fungi is evidenced. The recognition of the etiological agent in culture is important for the suitable treatment, once these fungi can cause irreversible damages or even death. The purpose of this study was to demonstrate, through the case of a patient who presented both mycosis associated, the need of complementary exams for the diagnosis of oral diseases, when routine laboratorial exams indicate the presence of another disease associated.

Família Enterobacteriaceae, Acinetobacter baumannii e Pseudomonados na microbiota bucal de pacientes mantidos em unidades de terapia intensiva

Enteric organisms, pseudomonads and other opportunistic microorganisms in the oral microbiota have been linked to serious infections in patients hospitalized in intensive care units (ICU). The present study evaluated the presence of family Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii in the mouth of patients in ICU, correlating it with oral and systemic conditions. Data on health, socioeconomic status, medication use, drug addiction, medical and family histories of patients held for more than 72 hours in the ICU with a diagnosis of severe infection or that developed this condition after entry in said unit were obtained. Fifty patients provided clinical samples of supragingival and subgingival biofilms, saliva and oral mucous membranes were collected, as well as respiratory secretions from patients with pneumonia, blood and urine for sepsis. The presence of target microorganisms was carried out by polymerase chain reaction (PCR) and by culture using selective media. The Chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients were poor. The family Enterobacteriaceae was the most prevalent, affecting 39.5% of the supragingival biofilm samples of patients attended in ICU and 18.6% of patients in the control group, besides the rods were the only group found in extraoral samples.

Enterococcus spp. em espécimes clínicos de pacientes atendidos em unidades de terapia intensiva

The relationship between the occurrence of enterococci in the oral microbiota and serious infections in patients hospitalized in intensive care units (ICU) has been established. This study evaluated the presence of Enterococcus faecalis and other species of this genus in the mouths of patients on ICU, correlating it with oral and systemic conditions. Data on health and socioeconomic, medication use, medical and family history of patients maintained for 72 hours in the ICU, diagnosed with severe infection or who have developed this condition after the entry to the unit were obtained. Fifty patients provided intraoral and extraoral clinical samples for analysis (above and subgingival biofilm, saliva and buccal mucosa, followed by obtaining samples of respiratory secretions for patients with pneumonia, and blood and urine for sepsis). The presence of target microorganisms was performed by polymerase chain reaction (PCR) and culture using selective media. The chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients showed poor. E. faecalis was significantly more frequent microorganism, followed by E. faecium. The use of broadspectrum antimicrobial action was associated with the presence of these opportunistic microorganisms. These bacteria were more frequent in patients with periodontitis or gingivitis. The results showed that enterococci associated with serious infectious processes may originate from resident microbiota of patients and its prevalence is not elevated in healthy individuals.

Opportunistic microorganisms in patients with head and neck trauma

The use of antimicrobial agents has facilitated the dissemination of multi-resistant microorganisms, compromising dental and medical treatment. The aim of this study was to evaluate the distribution of different opportunistic microbial species in patients who suffered head and neck trauma, under temporary maintenance in nosocomial environment, particularly intensive care units, on the occurrence of such microorganisms in the oral cavity of the patients. It was selected 38 patients subjected to head and neck traumas. After emergency surgical procedures, clinical samples of saliva, sub and supragingival biofilms and mucosal surfaces were collected at two different moments: just after stabilization of the patient and soon after patients’ release from medical units. The presence of opportunistic and superinfecting microorganisms was evaluated by culture on selective and non-selective media, and the presence of the family Enterobacteriaceae, as well as genera Enterococcus, Pseudomonas, and Staphylococcus was assessed by PCR. It was found that the use of antimicrobials, even for short periods of time was sufficient to facilitate colonization by microorganisms of the families Enterobacteriaceae and Pseudomonadaceae, as well as yeasts and enterococci. These results support the concept that medical and dental teams should make a periodically change of antimicrobials used in treatment protocols in hospital for head and neck trauma patients, in order to minimize dissemination of opportunistic or superinfecting microorganisms.

Meningite supurativa secundária a otite média e interna em um gato: relato de caso

Suppurative meningitis are rarely reported in dogs and cats. The present study aims to report the occurrence of suppurative meningitis secondary to otitis media and interna in a five-year-old female Persian cat examined at the Veterinary School of Unesp-Botucatu with acute progressive multifocal neurological alterations. Analysis of the cerebrospinal fluid (CSF) demonstrated predominance of neutrophils (90%) and the presence of bacteria. Therapy with antibiotics was initiated, but the animal came to die. beta-hemolytic Staphylococcus, beta-hemolytic Streptococcus and Proteus mirabilis were detected in fragments sent to culture. The present report demonstrates the importance of performing more specific exams such as complete CSF analysis in cases of otitis media and interna. This way, central nervous infections can be diagnosed and treated in a timely manner, as those are acute diseases with poor prognosis.

Fasceíte necrotizante: relato de dois casos

Necrotizing fasciitis is a rare dermatopathy that promotes subcutaneous tissue damage, associated to substantial morbidity and mortality if treatment is not initiated at the beginning of the condition. The objective of the present study is to report the occurrence of two cases of necrotizing fasciitis, one in a miniature female Pinscher and the other one in a female Poodle, both attended at the Veterinary Hospital of FMVZ/Unesp-Botucatu. The animals presented ulcerated, erythematous lesions with secretion and points of necrosis along fascial planes. Bacterial culture was positive for Streptococcus spp. The animals were treated with enrofloxacin, associated to topical cleaning of the lesions with saline solution and triclosan-based soap and rifampicin spray. Both animals presented total remission of lesions after approximately 15 days of treatment. The present report aims to alert veterinary clinicians to the severity of Streptococcus spp infections.

Contato com gatos: um fator de risco para a toxoplasmose congênita?

Toxoplasmosis is an important zoonosis and one of the most common parasitic infections throughout the world, which may cause among other problems several fetal pathologic alterations. Congenital toxoplasmosis is a result of transplacental transmission of Toxoplasma gondii due to a prime infection of the mother during pregnancy. Several studies have determined that the main risk factor for infection in pregnant women is the consumption of uncooked meat, which contributed from 30 to 63% of cases; other 6% to 17% of infections were related to contaminated soil. The relationship between pregnant women and their cats constitutes nothing more than a healthy experience when main transmission mechanisms and risk factors related to the disease are known.
