Translation, adaptation and validation of the Roland-Morris questionnaire--Brazil Roland-Morris.

The purpose of the present study was to translate the Roland-Morris (RM) questionnaire into Brazilian-Portuguese and adapt and validate it. First 3 English teachers independently translated the original questionnaire into Brazilian-Portuguese and a consensus version was generated. Later, 3 other translators, blind to the original questionnaire, performed a back translation. This version was then compared with the original English questionnaire. Discrepancies were discussed and solved by a panel of 3 rheumatologists and the final Brazilian version was established (Brazil-RM). This version was then pretested on 30 chronic low back pain patients consecutively selected from the spine disorders outpatient clinic. In addition to the traditional clinical outcome measures, the Brazil-RM, a 6-point pain scale (from no pain to unbearable pain), and its numerical pain rating scale (PS) (0 to 5) and a visual analog scale (VAS) (0 to 10) were administered twice by one interviewer (1 week apart) and once by one independent interviewer. Spearman's correlation coefficient (SCC) and intraclass correlation coefficient (ICC) were computed to assess test-retest and interobserver reliability. Cross-sectional construct validity was evaluated using the SCC. In the pretesting session, all questions were well understood by the patients. The mean time of questionnaire administration was 4 min and 53 s. The SCC and ICC were 0.88 (P<0.01) and 0.94, respectively, for the test-retest reliability and 0.86 (P<0.01) and 0.95, respectively, for interobserver reliability. The correlation coefficient was 0.80 (P<0.01) between the PS and Brazil-RM score and 0.79 (P<0.01) between the VAS and Brazil-RM score. We conclude that the Brazil-RM was successfully translated and adapted for application to Brazilian patients, with satisfactory reliability and cross-sectional construct validity.

Bone mineral density of the lumbar spine of Brazilian children and adolescents aged 6 to 14 years.

The authors performed a study of bone mass in eutrophic Brazilian children and adolescents using dual-energy X-ray absorptiometry (DXA) in order to obtain curves for bone mineral content (BMC) and bone mineral density (BMD) by chronological age and correlate these values with weight and height. Healthy Caucasian children and adolescents, 120 boys and 135 girls, 6 to 14 years of age, residents of São Paulo, Brazil, were selected from the Pediatric Department outpatient clinic of Hospital São Paulo (Universidade Federal de São Paulo). BMC, BMD and the area of the vertebral body of the L2-L4 segment were obtained by DXA. BMC and BMD for the lumbar spine (L2-L4) presented a progressive increase between 6 and 14 years of age in both sexes, with a distribution that fitted an exponential curve. We identified an increase of mineral content in female patients older than 11 years which was maintained until 13 years of age, when a new decrease in the velocity of bone mineralization occurred. Male patients presented a period of accelerated bone mass gain after 11 years of age that was maintained until 14 years of age. At 14 years of age the mean BMD values for boys and girls were 0.984 and 1.017 g/cm2, respectively. A stepwise multiple regression analysis of paired variables showed that the "vertebral area-age" pair was the most significant in the determination of BMD values and the introduction of a third variable (weight or height) did not significantly increase the correlation coefficient.

Resource utilization and cost of rheumatic fever.

OBJECTIVE: The socioeconomic effects of rheumatic fever (RF) in Brazil, including direct and indirect costs to patients and their families and to society, are largely unknown. We evaluated the utilization of resources and costs related to RF in a tertiary center caring for low income patients in the city of São Paulo, Brazil. METHODS: One hundred patients with RF, younger than 18 yrs, with followup of at least one year, were sequentially selected to provide complete information on a questionnaire. Additional data were collected from patients' charts. The utilization of resources was evaluated for each patient throughout the entire disease course. Costs were determined for patients and their families as well as for the society, using variables from 3 different systems: the national public health system, used by most lower income groups; the Brazilian Medical Association, which regulates charges and fees utilized by health plans and insurance companies; and costs charged by private practitioners, paid directly by patients. RESULTS: The RF population studied belonged to a low socioeconomic level. The mean monthly family income was $625.20 US. The mean disease duration was 3.9 yrs (range 1-10). Patients had a total of 1657 medical consultations, 22 hospital admissions, and 4 admissions to intensive care unit. Work absenteeism among parents was calculated as 22.9%, equivalent to 901 days of missed work; about 5% of the parents lost their jobs. Patients showed a high rate of school failure (22%). Considering the public system as a reference, direct, indirect, and total costs to society per 100 patients throughout the entire disease duration were $105,860 US ($271/patient/yr), $18,803 US ($48/patient/yr), and $124,663 US (US $319/patient/yr), respectively. When health care plan and private systems were taken as reference, the total costs were $423,550 US and $684,351 US, respectively. CONCLUSION: RF and rheumatic heart disease have an important socioeconomic impact in Brazil; costs of RF made up roughly 1.3% of annual family income. The estimated annual cost of RF for society in Brazil is $51,144,347.00 US.

Nail fold capillaroscopy: normal findings in children and adolescents.

OBJECTIVES: Capillaroscopy is a simple diagnostic method that permits noninvasive in vivo study of the capillary network. Studies designed to standardize capillary normality in children are limited. This article presents the capillaroscopic findings in healthy children and adolescents, thus making the application of this methodology viable for patients in this age range. MATERIAL AND METHODS: Healthy children were recruited from a private elementary school and junior high school. Nail fold capillaroscopy was performed using a stereomicroscope at 16 times magnification, addressing the following parameters: capillary morphology, capillary enlargement, devascularization, microhemorrhage, and subpapillary venous plexus visibility (PVS). These parameters were related to age, sex, ethnicity, and local periungal conditions. RESULTS: The sample comprised 329 individuals with mean age of 8.2 years. We observed atypical capillary morphology in 118 of the studied cases (36%), mainly bizarre capillaries in 90 (27%), meandering capillaries in 32 (10%), and bushy capillaries in 20 (6%). The enlarged capillary phenomenon was uncommon, being observed in 30 cases (9%). The number of capillaries per millimeter varied from five to nine. Deletion areas were detected in only seven individuals (2%). The subpapillary venous plexus was not visualized in 13 (4%) cases. Younger children presented higher PVS scores and fewer capillaries/mm as compared with older children. PVS scores were lower in males and in nonwhite children. Other variables were not associated with sex or ethnicity. CONCLUSIONS: The normal nail fold capillary network in children resembles that observed in adults with some differences, such as a lower number of loops per millimeter, a higher PVS score, and a higher frequency of atypical loops. This information is important for the diagnostic evaluation of children in the context of autoimmune rheumatic diseases.

Pediatric Escola Paulista de Medicina Range of Motion Scale: a reduced joint count scale for general use in juvenile rheumatoid arthritis.

OBJECTIVE: Different instruments are available to measure functional status in juvenile rheumatoid arthritis (JRA); however, none is based on the evaluation of joint range of motion (ROM). We designed and evaluated a ROM scale to be used as a complementary instrument in daily practice with JRA as well as in trials. METHODS: The 10 joint movements of the Pediatric Escola Paulista de Medicina Range of Motion scale (Pediatric EPM-ROM) were derived from 25 initial movements. The selection was based on 2 criteria: (1) consensus among 3 pediatric rheumatologists, one physical therapist, and one occupational therapist; and (2) choice of movements that presented the highest scores in a pilot study involving patients with JRA. The score for each joint ranges from 0 (full movement) to 3 (severe limitation) and the cutoff degrees of motion are, in general, based on the lack of ability to perform some activities of daily living. The test-retest reliability was assessed by administering the scale twice by the same observer, 4 to 10 days apart, always in the morning. The interobserver reliability was evaluated on the same day by 2 independent observers. Cross sectional construct validity was also assessed by correlating the values of some clinical variables with the scores of the Pediatric EPM-ROM scale. RESULTS: The instrument was applied to 34 patients with JRA, 11 systemic, 11 polyarticular, and 12 pauciarticular. The mean EPM-ROM score was 0.57 (SD 0.54, min 0, max 2.05). The test-retest and interobserver correlation coefficients were 0.96 and 0.98, respectively. The Pearson correlation coefficients comparing scores of the Pediatric EPM-ROM scale and other variables were satisfactory: Childhood Health Assessment Questionnaire, r=0.55 (p<0.001); American College of Rheumatology global functional class, r=0.56 (p<0.001); and number of limited joints, r=0.65 (p<0.001). CONCLUSION: Our results provide evidence that the Pediatric EPM-ROM scale is a valid instrument to measure joint ROM in JRA.

Juvenile fibromyalgia: clinical and polysomnographic aspects.

OBJECTIVE: To identify the child-mother diagnostic correlation in fibromyalgia (FM), to study sleep disturbance in juvenile FM, and to compare clinical aspects and sleep disorders between these groups. METHODS: We studied 34 children with confirmed FM aged 11 +/- 1 years, 10 children with diffuse pain, and 17 age and sex matched asymptomatic controls. The respective 61 mothers were included: 34 asymptomatic and 27 with FM. All participants were subjected to clinical evaluation, a sleep questionnaire, and nocturnal polysomnography, preceded by a night of adaptation. Sleep scoring was done visually and a computerized analysis was performed for alpha, theta, and delta waves in slow wave sleep (SWS). RESULTS: A significant predominance of mothers with FM was observed in the group of children with FM (71%) compared to children with diffuse pain (30%) and asymptomatic children (0%). According to the sleep questionnaire, the complaints of superficial sleep and nonrestorative sleep were more prominent in mothers with FM than in children with FM, whereas motor agitation during sleep was more frequent in the children with FM. Polysomnographic anomalies were also more prominent in mothers with FM than in children with FM in terms of decrease in sleep efficiency, increase of number of arousals during sleep, and alpha intrusion in SWS. Both FM groups presented an increased alpha + theta time/delta time index during SWS compared to respective controls, and mothers with FM also showed an increase in alpha time/delta time index during SWS, compared to asymptomatic mothers. A correlation was found between alpha + theta time/delta time index during SWS and intensity of clinical manifestations of pain and sleep anomalies in children and their mothers. CONCLUSION: Significant concordance was observed regarding FM diagnosis in children and their mothers. Sleep complaints and polysomnography findings were less prominent in affected children compared to mothers with FM. In addition, we observed a significant correlation between polysomnographic indexes, sleep anomalies, and pain manifestations in children and their mothers.

Ultrasonography in the early diagnosis of hip joint involvement in juvenile rheumatoid arthritis.

OBJECTIVE: To determine the value of ultrasonography in detection of early alterations and subsequent evolution of hip joint disease in patients with juvenile rheumatoid arthritis (JRA). METHODS: Hip joints of 53 patients were evaluated clinically, by conventional radiography and ultrasound. Ten children free of signs/symptoms related to rheumatic diseases were chosen as a control group. Nine patients were followed up 28 months after baseline examinations. The clinical, radiological, and ultrasound evaluations were repeated. RESULTS: Conventional radiography showed alterations in 10 patients (18.9%) who had shown clinical manifestations of advanced disease of the hip joint while ultrasound detected abnormalities in asymptomatic patients who had had normal radiographs. Ultrasound revealed the occurrence of 47.2% involvement in the hips of patients with JRA. Thus, ultrasound was apparently more sensitive than conventional radiographs in diagnosing changes in the hip joints of patients with JRA. Further, such involvement was found with greater frequency in the systemic and polyarticular types of JRA, in children less than 5 years of age, in those with longer duration of disease, and in those who belonged to a poorer functional class. In 3 of 9 patients who initially had normal radiographs and altered ultrasound, we found severe hip alterations upon reevaluation by radiography, after a period ranging from 21 to 39 months. CONCLUSION: Ultrasonography is a method of diagnosis that must be considered in hip joint evaluation of patients with JRA.

[Severe pulmonary thromboembolism caused by contraceptives in adolescents].

A 16 year-old female patient on oral contraceptive (gynera-ethynilestradiol+gestadone) for 4 months, presented with acute and severe pulmonary thromboembolism (PT), and was successfully treated with IV streptokinase. The contraceptive use was an importante risk factor for PT and the thrombolytic therapy provided early clinical improvement. Blood pressure, heart rate, and hypoxemia, along with echocardiography and pulmonary arteriography abnormalities, improved after this treatment.

Temporomandibular joint and mandibular growth alterations in patients with juvenile rheumatoid arthritis.

OBJECTIVE: To determine the frequency and type of lesions of the temporomandibular joints (TMJ) as well as orthodontic alterations present in patients with juvenile rheumatoid arthritis (JRA). METHODS: Twenty-six patients had their TMJ evaluated clinically and by high resolution computer tomography. The patients were also submitted to orthodontic evaluation. Children with isolated malocclusion were used as a control group. RESULTS: Computer tomography detected TMJ alterations in 13 (50%) patients with JRA. Bilateral mild lesions were the most frequent. TMJ alterations were especially observed in young patients with JRA with the systemic and polyarticular type of onset. Worse functional class and corticosteroid therapy were also related to TMJ involvement. We observed orthodontic alterations in 18 patients with JRA (69%): midline deviation, convex facial profile. Class II molar relation, crowded lower anterior teeth, anterior open bite, and reduction in the maximum opening of the mouth. Severe TMJ lesions were correlated to cephalometric alterations, suggesting decreased mandibular growth.

Crosscultural reliability of the Childhood Health Assessment Questionnaire.

OBJECTIVE: To translate into Portuguese the Childhood Health Assessment Questionnaire and to evaluate the reliability of the Portuguese version. METHODS: The original questionnaire was translated into Portuguese, without modifications, and it was administered to 53 children with juvenile rheumatoid arthritis and their parents. The reproducibility and construct validity were studied. RESULTS: We observed satisfactory Spearman's correlation coefficients among the instrument's score, a pain score (visual analog scale) and conventional clinical variables commonly used by the pediatric rheumatologists: disease activity index, number of involved joints, American College of Rheumatology functional class, and erythrocyte sedimentation rate. The test-retest reliability was established. CONCLUSION: Our results provide evidence of the reliability of the Portuguese version of the Childhood Health Assessment Questionnaire.

Symptomatic cardiac involvement in juvenile rheumatoid arthritis.

In a retrospective study of 172 patients with juvenile rheumatoid arthritis, symptomatic cardiac involvement occurred in 13 (7.6%) patients (11 systemic and 2 polyarticular). There was predominance of the male sex and in most patients the involvement occurred in the initial years of the disease. Pericarditis occurred in seven patients; perimyocarditis in four and myocarditis in two patients. In the follow-up, one of the patients with pericarditis died of an arrhythmia during pericardiocentesis for cardiac tamponade. Among the patients with myocarditis, three died of septicemia during active disease. One of these three patients had myocarditis associated with cardiac tamponade. Among the 172 patients with juvenile rheumatoid arthritis, five children died; four belonged to the symptomatic cardiac involvement group (P less than 0.001). Cardiac involvement, in particular myocarditis and cardiac tamponade, can be regarded as a factor of worse prognosis.
