Objective: To assess the prevalence of radiographically detectable destruction of the temporomandibular joints in children with juvenile idiopathic arthritis and to study the possible relationships between condylar destruction and type and duration of the disease, as well as the type of occlusion. Material And Method: The study group consisted of 66 children with juvenile idiopathic arthritis (27 boys, 39 girls; mean age, 11.9 years). The possible presence of condylar destruction was examined in panoramic radiographs. The medical history and the type of malocclusion were registered also. The statistical evaluation was performed by means of descriptive statistics, Student's t test, Pearson's chi-square, and an analysis of variance test. The whole procedure was repeated after a 4-week interval to estimate the error of the method. Results: Of the children with juvenile idiopathic arthritis, 50% showed some form of condylar destruction. Significant correlation was found between the type of the disease and the condyles affected. In the polyarticular type of juvenile idiopathic arthritis, 75% of the children presented affected condyles and 55.6% of them showed lesions bilaterally. The condylar affection was found to be independent of sex, although girls showed a tendency to bilateral lesions. In children with unilateral destruction, the right condyle was affected four times more frequently than the left. The duration of juvenile idiopathic arthritis seems to be significantly correlated to condylar destruction and especially to bilateral destruction. Conclusion: Children with juvenile idiopathic arthritis presented a remarkable prevalence of condylar destruction, which was correlated to the type and duration of the disease.

Background: The survival of people living with HIV (PLWHIVs) is increased and Health systems will have to deal with the early-aging-associated medical conditions. Objective: The objective of this study is to compare the clinical and biological profiles of PLWHIVs aged 50 and over and those aged less than 50 years. Material and methods: This study conducted at Kinshasa University Teaching Hospital (KUTH) covers 6 years. The clinical and biological characteristics of PLWHIVs aged 50 and over were compared with those under 50. Statistical analysis used the means ± SD, the calculation of frequencies, Student’s t-test and Chi-square. Results: PLWHIVs aged 50 or over represented 35.1%. Their average age was 58.0 ± 4.8 years. Women predominate among those under 50 and men among those 50 and over. Married people were more numerous (54% among those under 50). There were more unemployed (50% of PLHIV under 50). Patients 50 years and older were significantly classified as WHO stage 4 with a high frequency of history of tuberculosis, genital herpes, high blood pressure, smoking, vomiting, hepatomegaly, moderate elevation of diastolic blood pressure (DBP) and sytolic blood pressure (SBP), tuberculosis and anemia. Those under 50 had a significantly increased frequency of shingles, hepatitis B-hepatitis C, headaches and more survivals. The mean of Hb, HDL-C, and CD4s+ were significantly lower in patients 50 years and older, and urea, LDL-C, and ALAT levels were significantly higher. Conclusion: The average age was higher from 50 years old. These PLWHIVs were more frequently in WHO stage 4 with more common TB and anemia. Their Hb, HDL-C, and CD4s+ levels were lower while their urea, LDL-C and ALAT levels were significantly elevated.

Background: Spinal anesthesia is the preferred technique of anesthesia employed for caesarean sections. However, it is very often complicated by hypotension. Different drugs and techniques have been used to prevent the hypotension induced by spinal anesthesia. In this study, the effect of ondansetron on the prevention of hypotension after spinal anesthesia was evaluated. Objectives: To determine the effect of prophylactic ondansetron on prevention of spinal induced hypotension in elective caesarean section. Methodology: Eighty-six parturients planned for elective caesarean deliveries were randomized into two groups of 43 each. Group O received Ondansetron 4 mg (4 ml) and Group S received Normal Saline (4 ml) intravenously 10 minutes prior to spinal anesthesia. Blood pressure, heart rate, phenylephrine requirements, occurrence of nausea and vomiting and APGAR scores of neonates were compared between the groups. Hemodynamic data was analyzed using Student’s t-test for intergroup comparison and ANOVA was used for intragroup comparison. Categorical data was analyzed using Pearson Chi-Square test. For all determinants, p-value <0.05 was considered significant. Results: Occurrence of hypotension in Group O (20.9 %) was significantly lower than in Group S (72.1%) (p < 0.05). The mean arterial pressure was significantly higher in Group O at 2, 6, 8, 12 and 14 minutes (p < 0.05). The use of phenylephrine (37.21 mcg vs. 146.51 mcg, p < 0.05) and occurrence of nausea (11.6%, vs. 41.9% p < 0.002) was significantly lower in ondansetron group. Conclusion: Ondansetron is effective in preventing spinal induced hypotension in elective caesarean sections.

The fishery of mapará (Hypophthalmus marginatus) is of great economic importance in the Amazon region. Despite this, it is observed that the current norms of management disagree with the ethnoknowledge of fishermen of the Tocantins river. Therefore, there are many seizures and fines in the Tocantins Low region. This work appeared as a demand of the fishermen of the region and had as purpose to test the pertinence of the fishing legislation on the capture of the species and to provide subsidies for the adaptation of the norms to the local reality. For this, a mapará fishery was taken on the Pindobal Grande river, in the municipality of Igarapé-Miri, in the state of Pará. A sample of the captured individuals was collected, and identification, sexing and biometry were done. Fishing was described, and the sex ratio tested with the Chi-Square test and the mean length differences between the sexes with the Student's t-test. The results were compared with current legislation and literature data. The captured mapará individuals were mostly above 30 cm, as determined by legislation. It is concluded that, despite using a network that is prohibited, the capture of the species in the region acts selectively, due to the ethno-cognition and the fisherman's action ("taleiro"). Therefore, it is necessary that the legislation be revised, seeking the reconciliation between the conservation of ecosystems, the traditional knowledge and the socioeconomic development of the region.

Abstract The aims of this study were: 1) to evaluate the sports potential of young basketball players; 2) to identify variables that discriminate sports potential assessed by coaches; 3) to verifythe relationship between classification of the multidimensional profile of athletes and classification of the sports potential by coaches. Sixty-two young basketball players aged 15.6±1.1 years from U-15 (n = 24) and U-17 (n = 38) categories participated in the study. A test battery was applied to evaluate sports potential indicators: 1) anthropometric; 2) physicomotor; 3) psychological;4) skills;5) socio-environmental;6) maturational and 7) sports potential.Clusteranalysis was performed in three groups: high, medium and low potential. Student’s t-test was used for the comparison between athletes evaluated by the coach as excellent and the others and the Chi-Square test to verify the relationship between sports potential classifications. It was observed that in the high-potential group, athletes were chronologically older, with higher % predicted adult height (PMS), competitive and determined sports orientation, higher body size, lower skinfold summation, and greater physicomotor performance. In comparison with other athletes, high-potential basketball players presented higher stature, wider wingspan,longer limb length, greater predicted adult stature and higher Z score of the % PMS. It could be concluded that the multidimensional approach was useful for the evaluation of the sports potential of young basketball players, requiring the use of multidimensional variables, in addition to coaches’ opinion regarding the potential of their athletes.

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 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.

Background Few studies exist about risk factors for complications in subsequent biopsies. Purpose To explore risk factors for complications in initial versus subsequent biopsies in native and transplant kidneys, which may predict biopsy complications. Material and Methods In a multicenter study, 2830 native kidney biopsies (4.3% subsequent) were analyzed for major complications (1251 of these were also analyzed for minor) and 667 transplant kidney biopsies (29% subsequent) were analyzed for major and minor complications. No death or nephrectomy were described. Fisher’s exact test, Student’s t-test, chi-square analyses, and univariate and multiple binary logistic regression analyses were employed; P < 0.05 was considered significant. Results In initial native kidney biopsies, the frequency of major complications was higher in women compared to men (odds ratio 1.6, 95% confidence interval 1.1–2.2), in younger patients (50 vs. 54 years, P = 0.007), and in patients with lower weight (78 vs. 82 kg, P = 0.005). In subsequent native kidney biopsies, patients with major complications had a higher systolic blood pressure (145 vs. 132 mmHg, P = 0.03). In initial transplant kidney biopsies, biopsies with major complications had less glomeruli in the biopsy (17 vs. 24, P = 0.046). In subsequent transplant kidney biopsies, patients with major complications had a higher mean arterial pressure (112 vs. 98 mmHg, P = 0.002). In subsequent native kidney biopsies, there was a higher number of SLE-nephritis (12% vs. 4.6%, P = 0.001) compared to initial biopsies. Conclusion The different types of risk factors for complications in initial versus subsequent renal biopsies could be important for the clinicians to improve patients’ safety.

AbstractObjectives:To evaluate the effectiveness of interactive videodisc (IVD) instruction of paramedics through the use of computer analysis of trip sheets.Design/Setting:Prospective, controlled, in an urban 9-1-1, paramedic, emergency medical services (EMS) system with total call volume of 62,000/year; 15,000 advanced life support (ALS).Interventions:All 150 paramedics in the system received eight hours of IVD instruction covering five subject areas: 1) airway; 2) head/cervical trauma; 3) chest; 4) shock; and 5) cardiac arrest. Trip sheets from 9,943 runs in the pre-IVD period were subjected to computer analysis, and a compliance score was generated using previously developed algorithms that assigned a weight to each omission and commission. After a nine-month IVD training period, 4,303 cases were collected and analyzed in the post-IVD period. Statistical analyses were made using “Student's“ t-test and Chi-square with alpha set at 0.05.Exclusions:Only those records of adult patients who fit one of the five protocols were eligible for computer analysis. Of the 9,943 cases in the pre-IVD group, 480 (4.8%) were excluded, all due to inadequate data recording by the paramedics. A statistically similar portion, 233 (5.4%) of the 4,303 post-IVD instruction cases were excluded (p = .15).Results:Overall the mean compliance score of the pre-IVD group was 0.65 ±0.19 (±SD). The post-IVD group score was 0.65 ±0.19 (p = 0.99). Analysis of scores for each algorithm also showed no significant differences. This study had an observed power of .94 to detect a difference in compliance as small as 0.030.Conclusion:Eight hours of IVD instruction did not result in improved paramedic performance as judged by computer analysis of trip sheets.

Background The migraine brain is believed to have altered cortical excitability compared to controls and between migraine cycle phases. Our aim was to evaluate post-activation excitability through post-movement beta event related synchronization (PMBS) in sensorimotor cortices with and without sensory discrimination. Subjects and methods We recorded EEG of 41 migraine patients and 31 healthy controls on three different days with classification of days in relation to migraine phases. During each recording, subjects performed one motor and one sensorimotor task with the right wrist. Controls and migraine patients in the interictal phase were compared with repeated measures (R-) ANOVA and two sample Student’s t-test. Migraine phases were compared to the interictal phase with R-ANOVA and paired Student’s t-test. Results The difference between PMBS at the contralateral and ipsilateral sensorimotor cortex was altered throughout the migraine cycle. Compared to the interictal phase, we found decreased PMBS at the ipsilateral sensorimotor cortex in the ictal phase and increased PMBS in the preictal phase. Lower ictal PMBS was found in bilateral sensorimotor cortices in patients with right side headache predominance. Conclusion The cyclic changes of PMBS in migraine patients may indicate that a dysfunction in deactivation and interhemispheric inhibition of the sensorimotor cortex is involved in the migraine attack cascade.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.
