Helmintofauna de Hypsiboas raniceps (Cope, 1862) (Anura, Hylidae) no Pantanal Sul, Mato Grosso do Sul, Brasil

The helminth fauna of twenty-five Hypsiboas raniceps (Anura, Hylidae) specimens collected in the pantanal wetland, municipality of Corumbá, Mato Grosso do Sul State, Brazil was studied. Twenty (80%) specimens were parasitized with at least one helminth species. The helminth fauda is composed by the nematodes Oswaldocruzia mazzai, Cosmocerca podicipinus and Physalopteroides venancioi beyond the no identified species of the genus Rhabdias, Physaloptera and Raillietnema and the family Cosmocercidae. Cysts and larvae of nematodes were also found. Catadiscus propinquus and diplostomid metacercariae were the recovered trematodes

Diferentes métodos de diagnóstico molecular na diferenciação das espécies de Sarcocystis spp

The Sarcocystis genus includes obligatory two-host life cycle protozoan parasites. It is the most numerous of the six genera of the Sarcocystidae family. The infection caused by parasites of this genus is a zoonotic and cosmopolitan disease known as sarcosistosis or sarcosporidiosis. The sarcositosis though frequently asymptomatic in its definitive hosts can be fatal in its intermediate hosts. The usual diagnoses of sarcosistosis takes place through a histological demonstration of schizonts in blood vessels and organs, and the presence of cysts in muscle tissue by necropsy or biopsy, this second method still more common and based on morphological features of the sarcocyst. However, these methods can be inadequate to a precise identification of the infector species once that, besides the genus being of numerous species, these often present similar morphological features. Another factor that makes the diagnostic more difficult is the non specificity of some Sacocystis species to their hosts. Consequently, molecular diagnostic methods have been used in order to identify the infector species and the parasite specific biological cycles, demonstrating also new species and coevolutive aspects between parasite and host. Among the most employed molecular techniques the Polimerase Chain Reaction (PCR), the nested-PCR and the Restriction Fragment Length Polymorphism (RFLP) stands out

Avaliação uterina e ovariana de éguas por meio da ultrassonografia Doppler

Doppler ultrasonography is a new technology that has been study by researchers to improve the physiologic and pathologic knowledge about reproduction. This technology is based on Doppler-shifts frequencies or ultrasonic, these frequencies can be increase or decrease according to the movements of the red cells in the vessel. Color Doppler and power Doppler are the two possibilities to use the Doppler ultrasonography. Color Doppler is based in more the one color that show the direction of the blood f low and power Doppler is based in one color that change according of the flow intensity. Doppler ultrasonography can be demonstrated with the spectral mode to verify blood flow in large vessels, because of this, it is not use in equine reproduction. Studies in equine reproduction have been doing to verify uterus blood flow in cyclic mares and to observe the vascular perfusion in mares with cists, uterine vascular perfusion post breeding and verify the affects of drugs to decrease the uterus fluid in mares with problems in uterus perfusion. The ovarian irrigation during the estrus cycle was analyze with the measurement of the principal hormones during the estrus cycle in mares, the integrity of the corpus luteus, the irrigation of the future dominant follicle and the consequences in the ovarian irrigation after luteolyse induction also were study. Nevertheless, more than the knowledge that existed about Doppler ultrasonography, new studies have been doing to improve the forms to use Doppler ultrasonography in equine reproduction

Helmintofauna de duas espécies de anfíbios, Haddadus binotatus (Anura: Craugastoridae) e Ischnocnema guentheri (Anura: Brachycephalidae), da Mata Atlântica, no município de São Luiz do Paraitinga, São Paulo, Brasil

The Brazilian Atlantic Forest harbors a rich biodiversity with more than four hundred of amphibian species and many of these are endemic in this environment. This high rate of restricted endemism associated with global decline of amphibian diversity and density make it an important priority for the conservation of this ecosystem and to warrant intensive monitoring amphibian populations. Considering the importance that the parasites have on the ecology of their hosts, parasitic infections become a considerable factor in conservation biology. To expand the knowledge of this area, 23 specimens of Haddadus binotatus (Anura: Craugastoridae) and 36 Ischnocnema guentheri (Anura: Brachycephalidae) were collected from Santa Virginia, São Luiz do Paraitinga, São Paulo, between January and February 2010, to study their helminth parasites. Twelve helminth taxa were diagnosed and six of them were common to both hosts. The higher prevalence (P = 96%), mean abundance (MA = 11.7 ± 1.6) and mean intensity of infection (MII = 12.3 ± 1.6) were presented by H. binotatus compared to I. guentheri (P = 67%, MA = 2.4 ± 0.5, MII = 3.6 ± 0.6). Nematode species were found in different stages (cysts, larvae and adults) and acanthocephalans were found in both anurans. However, cestode species was found only in I. guentheri. Differences in parasitism of two species of frogs have been attributed to different sizes and micro-habitats of animals that allow different diets and contact with different helminth species. All helminths found have not been reported H. binotatus and also three new species records were noticed for I. guentheri

Estudo em telerradiografia em norma de 45º no tratamento da classe II com aparelho de Herbst

The aim of this retrospective study was to evaluate mandibular and maxillary changes induced by the use of Herbst applianceand by natural growth through oblique cephalometric radiographs in children with Class II division 1 malocclusion with mandibular retrusion. A sample of 49 individuals with age ranging from 8 to 10 years old (before growth peak) with Class II division 1, were into two groups: Herbst treated group (n=24) and control group (n=25). Both groups were paired for gender and chronological age. Statistical analysis was performed through Student’s t test. The Herbst appliance promoted the Class II correction in a 7 months period by mesialization of lower permanent first molars and distalization of upper permanent first molars. The Herbst appliance had no influence over the mandibular structure or the mandibular length. It was concluded that early treatment with Herbst appliance corrected the Class II malocclusion by means of dentoalveolar changes.

Efeitos esqueléticos e dentários decorrentes da expansão rápida maxilar

This study evaluated the maxillary transversal changes caused by the rapid maxillary expansion (RME) accomplished by Hyrax appliance. Sixteen children from both genders were selected and treated, with ages between 7.7 to 10.8 years, who presented unilateral or bilateral posterior crossbite. Postero-anterior radiographs were taken at the beginning of the treatment, end and post-retention period. The treatment promoted an average opening of 8.8 mm of IMD (intermolar distance), 2.33 mm of IAD (interapex distance) and none of IID (interincisal distance). At the end of retention period, relapse was observed, with a decrease of 4.3 mm of IMD, 1.23 mm of IAD, a non-significant enlargement of IID (0,38 mm).These results confirm the significant influence of Hyrax appliance on transverse dimensions, represented by enlargement of IMD and IAD and its effectiveness to solve posterior crossbites.

Avaliação da via aérea superior em pacientes classe III submetidos à cirurgia ortognática: revisão de literatura

Introduction: The configuration and dimensions of the upper airway are determined by anatomical structures such as soft tissues, muscles and craniofacial skeleton, composing or surrounding the pharynx. Anatomical abnormalities of the soft tissues and / or craniofacial skeleton may become more narrow upper airway. The orthognathic surgery, which is used in the correction of dentoskeletal deformities, also causes changes in the upper airway. Objective: In view of the facts presented, this article aims to review the literature on the changes of the upper airway in patients’ class III undergoing orthognathic surgery. Methodology: International Literature on Health Sciences (Pubmed ) and Port Journals CAPES original and review published between 1990 and 2010, in two bibliographic databases articles were selected. Results: thirty-nine (39) articles were selected for writing this review. Conclusion: The upper airway deformity and dental- skeletal class III should be carefully evaluated prior to orthognathic surgery and whenever surgical planning permit should prefer the maxillary advances to mandibular setbacks

Tratamento cirúrgico de canino incluso em mento: relato de caso

The mandibular and maxillary canines when well positioned in the arch, are important functionally and aesthetically. Although these teeth are frequently malpositioned in the dental arch, their absence of eruption are not common, occuring more frequently with the maxillary canine than the mandibular canine. The canine transmigration is a well-known pre eruptive phenomenon in which the tooth goes thru the facial midline, occurring more frequently in the mandible than in maxila. Females are more susceptible than males and the right side more than the left one. Normally the patients do not show any symptoms, and this condition is observed during radiographic exams to diagnose the late exfoliation of the deciduous canine or for any other purpose. Due to the relationship between impacted canines and pathologic lesions, infection, trauma to the adjacent teeth, pain, ectopic eruption and interference with prosthesis, it´s indicated the surgical extraction of these teeth. The goal of this article is to describe and discuss the surgical treatment of an impacted canine (43) in the chin.

Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.
