Avaliação clínica e hematológica em bezerros Nelore infectados experimentalmente com isolados de Babesia bigemina das regiões Sudeste, Nordeste e Norte do Brasil

A comparative study was made regarding the clinical and hematological alterations caused by isolates of Babesia bigemina from southeastern, northeastern and northern Brazil in experimentally infected Nelore calves. Eighteen calves between 7 and 9 months of age, without antibodies against Babesia sp and raised free from ticks, were used. Three animals were previously inoculated with 2.0×109 parasitic erythrocytes (PE) for each stabilate. The other 15 calves were subdivided into three groups, with five animals each, that were subinoculated with 1.0×1010 PE of the respective isolates. The clinical and hematological alterations were evaluated by the determination of parasitaemia, haemogram, plasmatic fibrinogen, reticulocyte count, descriptive analysis of the bone marrow and erythrocytic osmotic fragility, for 30 days, totalizing seven moments of observation. The follow-up of the immunological response by the indirect fluorescent antibody test was carried out daily until the 10th day after inoculation (DAI) and after that, on the 15th, 20th, 25th and 30th DAI. A mild clinical manifestation of the disease was observed. The laboratory findings revealed low levels of parasitaemia; decrease of the erythrogram values; absence of reticulocytes, initial decrease in the total count of leukocytes, neutrophils and lymphocytes with a posterior elevation of the number of these cells; hypercellularity of the erythrocytic series and decrease of the myeloid: erythroid relation which was more accentuated between the 8th and 12th DAI, and an increase of the erythrocytic osmotic fragility in the groups inoculated with the Southeast and Northeast isolates. None of the three isolates of B. bigemina gave rise to the clinical characteristic form of the disease, although they induced an humoral immune response.

Frutose em humanos: Efeitos metabólicos, utilização clínica e erros inatos associados

This article reviews the metabolism of fructose and sorbitol, their main clinical indications and the consequences of inadequate use. Fructose, an important carbohydrate in the diet, is present mostly in fruits and vegetables; it can also be synthesized from glucose in the organism, through the sorbitol. Fructose is known for its metabolism's inherent errors, whose clinical manifestations are potentially serious, as well as for its use as a glucose substitute in the diabetic patients' diet, due to its metabolism not being dependent from insulin. In the last years, especially in developed countries, the consumption of fructose has increased considerably, due to its use as a sweetener in industrialized foods. However, adverse side-effects may occur with the excessive ingestion of fructose, such as the increase in blood's triglycerides and cholesterol. Therefore, to know which are the patients' normal blood levels is quite important for establishing the safe amount of fructose to be prescribed, as well as for allowing the screening of metabolism diseases associated with fructose.

Diltiazem não induziu crescimento gengival em ratos. Análise clínica, histológica e histométrica

The administration of calcium channel blockers has been associated with gingival overgrowth. However, there are few studies in humans or animals that evaluated the effect of diltiazem on gingival tissues. The present study assessed the influence of diltiazem, at different dosages and treatment duration, on gingival tissues of rats, using clinical, histological and histometric analyses. Eighty young male rats were separated into eight groups according to the dosage and duration of treatment. Rats were treated for 20 or 40 days with a daily subcutaneous injection of 5, 20 or 50 mg/kg of body weight of diltiazem. The results confirmed that diltiazem did not induce gingival overgrowth in rats. For all animals, the evaluation did not show gingival alterations regardless of the dosages and periods of treatment. The histometric analysis showed no significant change in the area of epithelium and connective tissues, although after 40 days of treatment a decrease in the area of connective tissue was observed, without statistically significant difference from control groups. Within the limits of this study, we suggest that diltiazem did not induce gingival overgrowth.

O espectro médio de longo termo na pesquisa e na clínica fonoaudiológica.

BACKGROUND: One of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis--although frequently used--, as it is influenced by socioeconomic and cultural aspects as well as individual preferences. Many are the adjectives and methods used in this assessment, especially because of the subjectivity involved in the process, leading to incompatibilities between listeners and difficulties in reaching a consensus on the use of this or that terminology. In such a context, the voice laboratory and more specifically the acoustic computerized analysis, has guided and complemented speech-language treatments. Among the several possibilities of spectrographic analysis, the (Long-Term Average Spectrum--LTAS) quantifies the quality of voices, pointing differences between gender, age, professional--spoken and sang--and dysphonic voices. The LTAS has been used a lot in researches that investigate voice. As it evidences the contribution of the glottic source and of resonance to the quality of voice, it provides objective parameters for the evaluation of this aspect which usually depends on our auditive perception. AIM: to demonstrate how LTAS can be applied in voice research and in the speech-language therapy practice, describing both the technical aspects required for the production and interpretation of results, and its limitations. CONCLUSION: The area of voice research has developed a lot in these last two decades especially because of the advent of the voice and speech laboratory. For this reason, the knowledge about the applicability of more tools for voice analysis, as the LTAS, as well as the existing need for more studies in this area, will most certainly contribute for the creation of new research areas not only in the field of professional voice but also in the field of therapy.

Uso antenatal de corticosteóide e evolução clínica de recém-nascidos pré-termo

Objectives: To describe the use of antenatal corticosteroid and clinical evolution of preterm babies. Methods: An observational prospective cohort study was carried out. All 463 pregnant women and their 514 newborn babies with gestational age ranging from 23 to 34 weeks, born at the Brazilian Neonatal Research Network units, were evaluated from August 1 to December 31, 2001. The data were obtained through maternal interview, analysis of medical records, and follow-up of the newborn infants. Data analysis was performed with the use of chi-square, t Student, Mann-Whitney, and ANOVA tests and multiple logistic regression, with level of significance set at 5%. Results: Treatment was directly associated with the number of prenatal visits, with maternal hypertension and with the antenatal use of tocolytic agents. Babies from treated pregnant women presented better Apgar scores at the 1st and 5th minute, reduced need for intervention in the delivery room and lower SNAPPE II. They were born with higher birth weight, longer gestational age and needed less surfactant use, ventilation, and oxygenation time. After multiple logistic regression, the use of antenatal corticosteroid independently improved birth conditions, decreased ventilation time, being related to increased occurrence of neonatal sepsis. Conclusions: The use of corticosteroid was associated with better prenatal care and birth conditions, better preterm evolution but higher risk of infection. © 2007 Sociedad Chilena de Pediatría.

Ocorrência de mastite clínica e subclínica causada por Trichosporon beigelii em um rebanho leiteiro

Trichosporon beigelii was isolated from four and three Holstein heifers with clinical and subclinical mastitis respectively, during the extension activities of Nucleus of Mastitis Research - NUPEMAS - FMVZ - UNESP - BOTUCATU - BRAZIL. This fungus is considered extremely important because it is responsible for superficial skin infections, known as white piedra. According with literature, there is no record of isolation of this agent from mastitis in Brazil. This fact confirms the importance of microbiological studies to lead the treatment correctly to prevent the increase of bacterial resistance and secondary fungal infections that uses the inefficient antimicrobial as substratum for its development.

Variabilidade clínica na determinação da dose tóxica oral em intoxicação experimental por fluoroacetato de sódio em gatos

The sodium monofluoroacetate (FAC) or compound 1080 is a potent rodenticide used for a rodents and vertebrate pest control. It was prohibited in many countries because of its high toxicity, but in Brazil exist evidences of ilegal use causing the intoxication in children and domestic animals. The fluoroacetate metabolite, fluorocitric acid, blocks body energy production by inhibit the Krebs cycle, resulting in neurological and cardiacs signs. In the present study, four group of oral toxic dosis of the FAC were compared in cats. The best oral toxic dose for clinical signs presentation, without cause acute lethality, was 0,45mg/kg. The clinical variability was dosis dependent and its intensity, in crescent order, was: light signs (dose 1: 0,3mg/kg), light to moderate (dose 2: 0,4mg/kg), moderate to severe (dose 3: 0,45mg/ kg) and severe (dose 4: 0,5mg/kg). There was individual clinical variability between animals that received the same oral toxic dose.

Anatomia do nervo isquiático em mocós (Kerodon rupestris WIED, 1820) aplicada a clínica de animais silvestres

To know the origin of the ischiatic nerve in mocos (Kerodon rupestris Wied,1820) near by intervertebral forames and the muscling belonging to its routes were used 10 adult animals, from CEMAS-ESAM. After natural obit, they were fixed in formol (10%) and dissected to exposition and to singt of the ischiatic nerve. The results were indicated in percentage. Variations in the quantity of the lumber and sacral vertebras nere observed, five animals (50,00%) reveled seven lumbar vertebras and three sacral ones; two animals recrealed seven lumbar vertebras and four sacral ones, and two animals reveled six lumbar vertebras and three sacral ones. An animal (10,00%) revealed six lumbar vertebras and four ones. Therefore, the origin of the nerve was differentiated five animals (50,00%) had the participation of L 7,S 1,S 2; two animals (20,00%) with L 7,S 1; and a little part of S 2. Two animals (20,00%) with L 6,S 1,S 2, and an animal (10,00%) with L 6,S 1, and a little part of S 2. The last root of the ischiatic nerve in all its origins, contribute to the constitution of the first root of pudental nerve. It was verified that in all its route, the ischiatic nerves (100,00%) ceded branches to the muscles: medial gluteus, deep gluteus, superficial gluteus, emiting muscular branches to the femoral biceps or to thigh, and to the semimembranous and semi-tendinous muscles, that is continuous with a high calibre trunk, originating the fibular nerve(sideways), the tibial nerve(medial) and the lateral plantar sural cutaneous nerve (caudal).

Anoftalmia congênita clínica - alterações oculares e sistêmicas associadas

Purpose: To describe alterations observed in patients with congenital clinical anophthalmia and the occurrence of association with other ocular and extra ocular abnormalities. Methods: An observational retrospective study was conducted evaluating 12 patients with congenital clinical anophthalmia at Faculdade de Medicina de Botucatu-UNESP, between 1992 and 2005. In those patients it was observed the ocular abnormalities, severity, laterality, follow-up and to systemic abnormalities associated. The congenital clinical anophthalmia have been associated to major severity abnormalities extra-oculars, mainly when the anophthalmia was bilateral, such agenesis of corpus callosum, others craniofacial anomalies and cardiac defects. In the cases unilateral, the alteration associated more frequently was the facial asymmetry, showing the direct correlation between anophthalmos and development of orbit and face. Conclusion: There was relation between congenital clinical anophthalmia and ocular abnormally and extra-ocular abnormally. Patients with bilateral anophthalmos disease have more severe alterations. anophthalmia congenital attends a course with abnormalities of development of the face.

Patologia clínica em aves de produção - Uma ferramenta para monitorar a sanidade avícola - Revisäo

Clinical pathology has been used in veterinary medicine for many years to evaluate metabolic changes that may indicate any sign of disease in animals. Even though the use of blood parameters is routine in companion animals, it is not commonly used for avian clinical evaluation either wild or production birds. Among others, the lack of information of avian blood reference values has limited the use of this tool in avian medicine. The blood parameters in avian medicine are helpful to evaluate aspects related to animal health for wild and also production birds. Thus, this review paper presents some ways to use clinical pathology parameters to evaluate and to monitor the avian health.

It was an observational study with 22 subjects, both genders, with diagnosis of stroke, ages ranged from 23 to 86 years old. The subjects were submitted to balance evaluation with Berg's Scale of Functional Balance (BSFB), Brazilian version, composed by fourteen tasks. Results. Stroke patients had an average punctuation of 37 points, showing a high risk of falls. There was no significant correlation between the patient's age and time of lesion with BSFB punctuation. Conclusion. This study showed that stroke patients present high risks of falls, independently of age and time of lesion.

Razões para substituição de restaurações em clínica integrada

Objective: To analyze the reasons for replacing amalgam and composite resin restorations of patients treated at the Integrated Clinic Discipline of the Dental School of Araçatuba (UNESP), SP, Brazil. Method: After examining the patients for data collection to obtain a diagnosis, the treatment plan was outlined using a clinical form containing the restorations to be replaced, the reasons for replacing, the restorative material of choice and the number of restored surfaces. Next, all restorations indicated for replacement were examined as to their real need of replacement by 5 calibrated examiners taking into account the theorical concepts on the proposed criteria for the need of replacing or not. The analyzed period comprised 5 years (2001 to 2005). The criteria adopted for replacement were attached to the data collecting form in order to standardize the analysis of the restorations. Results: 856 patients were treated within the studied period and 753 needed restoration replacement. The main reasons for replacing amalgam restorations were defective marginal adaptation (40.9%), recurent caries (24.1%) and deficient anatomical form (15.4%). The main reasons for replacing resin restorations were esthetics (31.4%), defective marginal adaptation (29.2%) and recurent caries (20.7%). Conclusion: In spite of the little clinical experience of the studied population (undergraduate students), the reasons for replacing restorations were in accordance with the literature, having estehtics as the main reason for the replacement of composite resin restorations and defective marginal adaptation for amalgam restorations.
