Otological findings and other symptoms related to temporomandibular disorders in young people.

In a prospective, observational study between April and November 2017 we evaluated the correlation between temporomandibular disorder (TMD), and otological signs and other symptoms in a sample of 251 patients. First, a simplified anamnestic questionnaire was applied for the diagnosis of TMD and the following symptoms were recorded: otalgia, tinnitus, vertigo, pruritus of the ear, feeling of hearing loss, fullness in the ear, headache, pain in the eye, neck pain, back pain, and dizziness. Some degree of TMD was detected in 177 of the participants (70.5%). Among the otological symptoms studied, significant associations were found with tinnitus (<0.001), ear pain (<0.001), feeling of hearing loss (<0.001), and vertigo (<0.001). There were also significant associations with non-otological symptoms, the most common being back pain (<0.001), headache (<0.001), neck pain (<0.001), pain in the eye (<0.001), and dizziness (0.001). Our findings show that the higher incidence of both otological and non-otological symptoms was associated with a progressive increase in the severity of TMD.

Imunogenicidade da proteína M recombinante de Streptococcus equi subsp. equi coadministrada com um adjuvante molecular / Immunogenicity of recombinant M protein of Streptococcus equi subsp. equi co administered with a molecular adjuvant

The strangles is an infectious disease that affects horses from all ages and causes important economic losses in the equine-related business. The aim of this work was to evaluate the immunogenicity of the recombinant M protein from Streptococcus equi (rSeM) co-administered with the recombinant heat-labile enterotoxin B subunit from Escherichia coli (rLTB) in mice and horses. A total of 72 female Balb-c mice were divided into eight groups and 18 horses were divided into six groups. The animals were inoculated by intramuscular (IM) or intranasal (IN) routes with different treatments of rSeM, rLTB and/or Al(OH)3. The results obtained in both species, independent of administration routes, demonstrated that rSeM + rLTB had higher levels of specific serum immunoglobulins, however, in mucosal immunity the increase was not identified. Thus, the use of rSeM as vaccine antigen and rLTB as adjuvant can be a potential tool in the control of equine strangles.(AU)

Mutagenic potential of water from Pelotas Creek in Rio Grande do Sul, Brazil.

Water resource degradation is one of mankind's greatest worries, as it causes direct and indirect damage to the associated biota. We initiated a water monitoring study in Pelotas Creek in 2003 in order to assess the mutagenic effect of the creek's waters. Allium cepa cells exposed to water samples and a chronically exposed macrophyte were analyzed, through evaluation of the mitotic index, mitotic anomalies, interphase anomalies, and total anomalies. Five points were chosen along the lower course of Pelotas Creek, from which water samples and floating pennywort (Hydrocotyle ranunculoides, Apiaceae) were collected in 2006 and 2007. The enteric bacterium Escherichia coli was found at all sampling points; in the physical-chemical analysis, a few variables exceeded permitted limits, pH (from 6 to 9), chloride (250 mg/L), hardness (from 10 to 200 mg CaCO(3)/L), and conductivity (100 microOmega/cm). There was an increased number of cytogenetic anomalies in exposed A. cepa cells and in the pennywort in 2006 relative to 2007, which may be explained by the increased rainfall, which was three times greater in 2007 at some stations than in 2006.Omega/cm).
