Objective: To evaluate the growth of exclusively breastfed infants from birth to 6 months of life.Methods: This was a longitudinal study of 184 children who received primary care at a public institution (Exclusive Breastfeeding Stimulation Program, PROAME) in Belém, state of Pará, Brazil, between February 2000 and January 2001. A total of 102 children completed the study. All were born at full term with a birth weight greater than or equal to 2,500 g. No events were recorded during the neonatal period and the infants were exclusively breastfed, on demand, since their birth. The infants were followed up monthly, and the weight and length measured at birth and at the end of the first, fourth and sixth months of life were compared to the 50th percentile line of the NCHS growth charts and to other previous studies of Brazilian children who were exclusively breastfed.Results: Growth was adequate for all the children, who doubled their weight before the fourth month of life. Despite a slow-down in weight and height gain after the fourth month, the weight averages at 6 months were greater than the standards used for comparison. Conclusions:The average weight of these exclusively breastfed children was above the 50th percentile of the NCHS curve at 6 months, thus confirming the nutritional advantages of breast milk, especially when the mothers receive guidance regarding the appropriate techniques for breastfeeding.

OBJECTIVESTo assess the food intake pattern and the nutritional status of children with cerebral palsy. METHODSCross-sectional study with 90 children from two to 12.8 years with cerebral palsy in the following forms: hemiplegia, diplegia, and tetraplegia. Nutritional status was assessed by weight, height, and age data. Food intake was verified by the 24-hour recall and food frequency questionnaire. The ability to chew and/or swallowing, intestinal habits, and physical activity were also evaluated. RESULTSFor 2-3 year-old age group, the mean energy intake followed the recommended range; in 4-6 year-old age group with hemiplegia and tetraplegia, energy intake was below the recommended limits. All children presented low intake of carbohydrates, adequate intake of proteins and high intake of lipids. The tetraplegia group had a higher prevalence of chewing (41%) and swallowing (12.8%) difficulties compared to 14.5 and 6.6% of children with hemiplegia, respectively. Most children of all groups had a daily intestinal habit. All children presented mild physical activity, while moderate activity was not practiced by any child of the tetraplegia group, which had a significantly lower height/age Z score than those with hemiplegia (-2.14 versus -1.05; p=0.003). CONCLUSIONSThe children with cerebral palsy presented inadequate dietary pattern and impaired nutritional status, with special compromise of height. Tetraplegia imposes difficulties regarding chewing/swallowing and moderate physical activity practice.

Objective:To evaluate the quality of life in children and adolescents with sickle cell disease attending a blood reference center, and to assess the quality of life of their relatives.Methods: Cross-sectional study that included 100 patients with sickle cell disease, which were divided into three subgroups according to age: 5 to 7 (n=18), 8 to 12 (n=32), and 13 to 18 years-old (n=50), and their parents. The Control Group included 50 healthy children and adolescents from a public local school, also divided into the same three age subgroups and their caregivers. The Pediatric Quality of life Inventory (PedsQL), version 4.0, was applied in both groups. The generic questionnaire Medical Outcomes Study 36 -Item Short-Form Health Survey (SF-36) was applied to the relatives. The answers were linearly transformed into a score and compared by nonparametric tests.Results: The PedsQL scores of patients were significantly lower than those obtained in the Control Group (p<0.0001) in all studied areas (physical, emotional, social skills, and school activities). Similarly, SF-36 scores applied to the patients' parents were lower than those obtained in the Control Group in all studied aspects (p<0.0001).Conclusions: Sickle cell disease affects the quality of life of children, adolescents, and their families. Patients sense restrictions in the emotional, social, family and physical aspects, among others.Key-words: quality of life; anemia, sickle cell; children; adolescents.

Helicobacter pylori and immune thrombocytopenic purpura (ITP) association is not well established in chronic ITP (cITP) in children, although the cure of thrombocytopenia in approximately half of H. pylori eradicated adult patients has been described. The aim of this study was to investigate the effect of H. pylori eradication on platelet (PLT) recovery in cITP children and adolescents through a randomized, controlled trial. A total of 85 children (mean age 11.4 years) with cITP were prospectively enrolled. Diagnosis of H. pylori was established by two locally validated tests, (13)C-urea breath test and monoclonal stool antigen test. Twenty-two infected patients were identified, and randomly allocated into two groups: H. pylori treatment group (n = 11) and the non-intervention control group (n = 11). The control group was offered treatment if the thrombocytopenia persisted after the follow-up. At baseline, there were no differences regarding age, sex, duration of disease, and PLT count between groups. Sixty three of 85 patients were uninfected. PLT response was classified as complete response: PLT > 150 × 10(9 )l(-1); partial response: PLT 50-150 × 10(9 )l(-1), or an increase of 20-30 × 10(9 )l(-1); no response: PLT < 50 × 10(9 )l(-1) or an increase of <20 × 10(9 )l(-1) after at least 6 months of follow-up. Complete response was observed in 60.0% (6/10, one excluded) H. pylori eradicated patients vs. 18.2% (2/11) in non-eradicated patients (p = 0.08; OR = 6.75) after 6-9 months of follow-up. Among uninfected patients, only 13.8% (8/58) presented complete response. Two non-treated controls were treated after 6-12 months of follow-up, and PLT response was observed in 61.5% (8/13) of H. pylori eradicated patients, and in 19.0% (11/58) of uninfected patients (p = 0.004). Cytotoxin associated gene A and vacuolating cytotoxin gene A IgG antibodies were present in almost all infected patients. Therefore, the study suggests that H. pylori eradication plays a role in the management of H. pylori infected cITP children and adolescents.

Conflict of interest: noneObjective: The objective was to determine the prevalence of iron deficiency and iron deficiency anemia among exclusively breastfed infants from one to six months of life and to identify associated risk factors. Methods: This is a cohort study of the hemoglobin and serum ferritin levels of 102 healthy full-term infants, weighing more than 2500 grams (5.5 pounds) at birth, evaluated for growth development and supported to promote exclusive breastfeeding. Hemoglobin and ferritin levels were measured in the first, fourth, and sixth months of life. The hemoglobin and ferritin levels of the mothers were also measured in the first month postpartum. Results: At four months, 5.7% presented iron deficiency and 3.4% had iron deficiency anemia. At six months, the percentage of children with iron deficiency increased more than four times, reaching 26.1%, while iron deficiency anemia was present in 23.9% of the infants studied. Iron deficiency at six months of age was significantly correlated to growth velocity. Conclusion: According to the results of this study, exclusive breastfeeding protects infants from iron deficiency and iron deficiency anemia for the first four months of life. After this age, in accordance with the literature, the findings of this study demonstrated an increase in anemia and iron deficiency rates, adding to evidence that supports the monitoring of iron levels in exclusively breastfed children presenting higher weight gains beginning at four months of age.

CONTEXT AND OBJECTIVE: Transcranial Doppler (TCD) detects stroke risk among children with sickle cell anemia (SCA). Our aim was to evaluate TCD findings in patients with different sickle cell disease (SCD) genotypes and correlate the time-averaged maximum mean (TAMM) velocity with hematological characteristics. DESIGN AND SETTING: Cross-sectional analytical study in the Pediatric Hematology sector, Universidade Federal de São Paulo. METHODS: 85 SCD patients of both sexes, aged 2-18 years, were evaluated, divided into: group I (62 patients with SCA/Sß0 thalassemia); and group II (23 patients with SC hemoglobinopathy/Sß+ thalassemia). TCD was performed and reviewed by a single investigator using Doppler ultrasonography with a 2 MHz transducer, in accordance with the Stroke Prevention Trial in Sickle Cell Anemia (STOP) protocol. The hematological parameters evaluated were: hematocrit, hemoglobin, reticulocytes, leukocytes, platelets and fetal hemoglobin. Univariate analysis was performed and Pearson's coefficient was calculated for hematological parameters and TAMM velocities (P < 0.05). RESULTS: TAMM velocities were 137 ± 28 and 103 ± 19 cm/s in groups I and II, respectively, and correlated negatively with hematocrit and hemoglobin in group I. There was one abnormal result (1.6%) and five conditional results (8.1%) in group I. All results were normal in group II. Middle cerebral arteries were the only vessels affected. CONCLUSION: There was a low prevalence of abnormal Doppler results in patients with sickle-cell disease. Time-average maximum mean velocity was significantly different between the genotypes and correlated with hematological characteristics.

Objective: To describe the socioeconomic and nutritional characteristics of children and adolescents with sickle cell anemia.Data sources: The present study is a systematic literature review based on published scientific articles. The searches were carried out using the electronic database of the National Library of Medicine, National Institutes of Health- PubMed. Two searches of articles published in the last 20years and without limitation of language were carried out. Thefirst one started from the Medical Subject Headings term “Anemia, Sickle Cell” associated with “Socioeconomic Factors”; and the second started from the term “Anemia, Sickle Cell” associated with “Anthropometry”. Thesearches were directed to research conducted on humans in the age group from 0 to 18years.Data synthesis: The final selection was composed by 11 articles on socioeconomic characteristics and 21articles on nutritional characteristics. Allstudies included children and adolescents with sickle cells disease (age range 0-18years), both genders, and most of them of black ethnicity. Families of children and adolescents with sickle cell anemia were of predominantly low socioeconomic status. Parents had lower educational levels when compared to parents of healthy children and adolescents. Body measurements (weight and height) and anthropometric indicators of children with sickle cell anemia were often lower when compared to healthy groups or reference populations.Conclusions: Children and adolescents with sickle cell anemia have socioeconomic limitations and worse nutritional conditions, when compared to reference populations. These limitations may lead to worse growth and greater occurrence of possible complications that can impair their quality of life.
