ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

Objective: To observe if dental alterations in premolars are associated with the rupture of the follicle bone crypt caused by a periapical lesion in the predecessor molars. Study design: This is a cross-sectional study. Data collection consisted of the analysis of medical records, a socioeconomic questionnaire, and dental clinical examination. Records from patients with a history of a radiographically visible periapical lesion in lower primary molars submitted to pulp therapy or extraction from a university dental clinic were selected. Successor premolars were clinically evaluated for the presence of enamel development defects, shape alterations, and eruption deviations. The descriptive analysis of data was performed, and Fisher’s exact tests, linear trend chi-square, and the Student’s t-test were applied. Results: Forty-eight permanent teeth were from 36 patients were evaluated in this study, and 20 (41.7%) of the 48 examined premolars showed a radiographic image suggestive of the rupture of the bone crypt. Rupture of the follicle bone crypt was not associated with the occurrence of enamel alterations in premolars (p = 0.418). An association between dental alterations and age over six years at the time of intervention was observed (p = 0.043). Conclusion: The presence of enamel alterations of premolars was not associated with the rupture of the follicle bone crypt caused by a periapical lesion in predecessor molars.

Aim: To investigate the percentage of correctness (PC) of the Nasal Index (NI) in human skeletons for determination of sex, ancestry and estimation of age in the Brazilian population. Methods: This was a cross-sectional study of 173 human skulls belonging to the Piracicaba Dental School. 93 skeletons were males and 80 females; 34 were aged up to 39 years, 56 between 40 and 59 years, and 83 60 years or older; 96 were from white individuals, 49 were from mixed-race and 28 from black individuals. High-precision digital caliper was used to measure nasal height (NH=ANS-nasion) and the maximum nasal width (NW) values, which were applied into the formula NI=NW/NHx100. The data were submitted to discriminant analysis and Student’s t test with equal variances, Mann-Whitney, F (ANOVA), Tukey and Kruskal Wallis, 5% significance level. Results: Dominant nasal type in the Brazilian population was the mesorine. Males showed nasal height and width values greater than those of females, with statistically significant differences in all measurements (p≤0.021) and PC of 76.6%. Similar nasal measurements were found regardless of age (p>0.05), with PC of 41.7%. Ancestral analysis revealed that black individuals have greater nasal width (26.35) and nasal index (53.67) than white ones (24.60 and 49.25), while mixed-race individuals showed intermediate values (25.36 and 52.13) (p<0.05). Nevertheless, these measurements presented an estimated PC of 54.3%. Conclusion: The Nasal Index can be better used for sex determination than for estimation of age and ancestry in the Brazilian population, as the latter showed intermediate and low percentage of correctness, respectively.

Objective The aim of this study was to identify lymphoscintigraphic changes associated with lower-extremity oedema after the harvesting of the saphenous vein using a series of short Q2 incisions for coronary bypass. Method Forty-four patients (32 males and 12 females) with a mean age of 62.7 ± 7.8 (47–75 years old) were evaluated in a retrospective, quantitative, cross-sectional study from June 2007 to January 2008, three to 188 months (mean: 46 months) after the surgical procedure. Assessment was by water displacement volumetry and lymphoscintigraphy of the lower limbs. Results expressed as means with standard deviations were compared employing the Student's t-test and the chi-square or Fisher's exact tests were used to compare data expressed as frequencies. An alpha error of 5% was considered acceptable ( P ≤ 0.05). Results The presence of dermal backflow, as identified by lymphoscintigraphy with an accumulation of radiotracer in the thoracic duct and popliteal lymph nodes was significantly greater on the operated side. Conclusion There was a significant association between dermal backflow and delayed oedema.

OBJECTIVE: A cross-sectional study of haptoglobin (Hp) in myasthenia gravis (MG) was designed, with the objective to identify its values and correlate them with different disease status. METHOD: 46 patients were enrolled in the study, all having disease severity established according to the quantitative myasthenia gravis strength scores (QMGSS). Based on the functional scale determined by Myasthenia Gravis Foundation of America (MGFA) recommendations, patients were classified as having: complete stable remission (CSR; n=10); minimal manifestations-0 (MM0; n=6), minimal manifestations-1 (MM1; n=4); pharmacological remission (PR; n=6). Two other groups participated: thymomatous patients (T; n=10) and patients without imunosuppression or thymectomy, until the assessment for Hp (WIT; n=10). Hp dosage was done by immunonephelometry, blindly to clinical data. Student's t-test, Anova test and linear regression were employed for statistical analyses. RESULTS: Statistically significant differences occurred between CSR+MM0xWIT groups (86.62x157.57, p<0.001) and PR+MM1xWIT groups (73.93x157.57, p<0.001). Linear regression showed correlation between Hp levels and QMGSS (r=0.759, p<0.001). CONCLUSION: Our results suggest that Hp may be useful in clinical practice as a disease severity marker in MG.

Introdução: A agilidade é fundamental para o judô, uma luta que demanda força e potência e utiliza mudanças bruscas de direção. Pouco se investigou, no Brasil, a respeito da qualidade física agilidade em crianças escolares pré-puberes.Objetivo: Comparar o nível de agilidade entre crianças praticantes e não-praticantes de judô de uma escola pública.Métodos: Pesquisa descritiva de corte transversal comparativa, da qual participaram 77 crianças de ambos os sexos: 47 praticantes de judô e 30 não praticantes. Teste t de Student para amostras independentes foi aplicado para a comparação entre os grupos.Resultados: Os praticantes regulares de judô exibiram maiores níveis de agilidade (10,98±0,79 segundos) do que os não praticantes de judô (13,48±0,74 segundos) e a diferença foi significativa (p=0,0001).Conclusão: Crianças que praticam judô apresentaram níveis maiores de agilidade do que as participantes de iniciação esportiva em outras modalidades, sugerindo que o treinamento de judô pode favorecer o desenvolvimento dessa capacidade física mais do que as demais modalidades. Outros estudos de intervenção devem ser conduzidos para esclarecer essa associação. Comparison of Agility Levels in Judo-Practicing and Non-Practicing School-Age Children: A Cross-Sectional StudyIntroduction: Introduction: Agility is fundamental to judo, a fight that demands strength and power and uses sudden changes of direction. Little has been investigated in Brazil regarding physical quality agility in prepubescent school children.Objective: To compare the level of agility between practicing and non-practicing children of judo in a public school.Methods: A descriptive comparative cross-sectional study was conducted in which 77 children of both sexes participated: 47 judo practitioners and 30 non-practitioners. Student's t-test for independent samples was applied for comparison between groups.Results: Regular judo practitioners exhibited higher levels of agility (10.98 ± 0.79 seconds) than non-judo practitioners (13.48 ± 0.74 seconds) and the difference was significant (p = 0.0001).Conclusion: Children who practice judo showed more agility than participants of sports initiation in other modalities suggesting that judo training may favor the development of this physical capacity more than the other modalities. Further intervention studies should be conducted to clarify this association.

Background A family history of hypertension is a risk factor forhypertension in children. Past studies have reported a significantrelationship between elevated blood pressure in children andhypertensive parents.Objective To assess for an association between blood pressure inchildren and that of their parents.Methods A cross-sectional study was conducted in 90 childrenaged 6-18 years in Baringin Village, Panyabungan, from May toJune 2010. Subjects were collected by consecutive sampling.Classification of hypertension was based on Fourth Task ForceGuidelines by measuring blood pressure, height, and weight. Weused Student's T-test to analyze numerical data. Simple linearregression was used to investigate the relationship between bloodpressures of children and their parents.Results Of the 90 participants recruited, 24 boys and 17 girlshad hypertensive parents. The mean systolic (SBP) , diastolic(DBP) and arterial blood pressure (MABP) were significantlyhigher in children with hyperten sive parents than in childrenwith normotensive parents [ (SBP 116. 7 (SD 7 .07) vs. 87 .1 (SD13.57) mmHg; P=0.0001), (DBP 77.8 (SD 8.33) vs. 51.8 (SD11.70) mmHg; P=0.0001), (MABP 90.7 (SD 7.41) vs . 63 .6(12.10) mmHg; P=0.000 1] . There was a significant relationshipbetween elevated SBP in boys and their fathers, as indicated bythe correlation coefficient (r =0.806; P=0.0001).Conclusion The blood pressure is significantly higher in childrenwith hypertensive parents than in those with normotensiveparents. There is a correlation between SBP in boys and that oftheir fathers.

Background: Assessment of language is very important to detect atypically developed children. In this sense, psycholinguistic abilities are predictors of developmental functioning. The aim of this study was to compare ages of psycholinguistic processes between atypically and typically developed children. Material/Methods: In this cross-sectional study, six-, seven- and eight-year-old children from Cordoba (Argentina) (n= 28) were evaluated with the Spanish version of Illinois Test of Psycholinguistic Abilities (S-ITPA). Statistical analysis included Student’s t-test in order to find differences between groups. Results: In the six-year-old sample, those with atypical language showed significantly lower psycholinguistic ages in: global psycholinguistic age, auditory association, and verbal expression, auditory reception, auditory sequential memory, grammatical closu re, and auditory closure, manual expression. In seven-year-old sample differences were found in grammatical closure and auditory closure. In eight-year-old group, atypical language sample showed lower psycholinguistic ages in auditory association, verbal expression and auditory sequential memory. Conclusions: This evidence establishes a limit stage corresponding to 6 years of age, which reflects the consolidation and integrity of language and the aptitudes involved. In later ages (e.g. seven and eight years), results may be biased by acquired formal learning abilities.
