Realizou-se dois estudos transversais em 2002 (N=379) e 2003 (N=397) onde estimou-se a prevalência de enteroparasitas em crianças de cinco creches municipais de Botucatu, SP. Coletou-se variáveis socioeconômicas, sanitárias e educacionais e realizou-se exames coproparasitológicos. Giardia duodenalis apresentou prevalência de 23,7% (2002) e 21,4% (2003) seguido por Cryptosporidium sp com 15,5% (2002) e 3,7% (2003).

Equine infectios anemia of traction equids in the Cuiaba Districty, MT, Brazil

The present study it had for objective to search the AIE in equids traction of the city of Cuiaba, of which if it extracted an inquiry epidemiologist and a sampling of blood serum of 113 animals (110 equines and 3 mules) that they transited for the public ways. The sampling of the animals was random how much to the age (of 8 months the 20 years) and sex of the animals where 67 (60.9%) were of females and 46 (41.8%), of males, with a average of 22 working hours per week. The samples of blood had been analyzed by means of the technique of AGID test. The results of the blood tests had indicated that of the 110 examined samples of blood serum of the equines, thirteen (11.8%) were positive, being seven of female (10.4% of the total of females) and 6 males (13.0% of the total of males), all no symptoms animals and the age of the positive animals was concentrated in the band of 6 10 years, representing 84.6% (11 animals). The results of the blood tests had also indicated that of three mules analyzed, 1 (33.3%) was positive.

Evolução neurológica e eletrencefalográfica em crianças após meningencefalites purulentas

Twenty children with diagnosed meningitis were available for prospective study; each was submitted to neurological and electroencephalographic examination, Distractability Quotient (Gesell) and Intelligence Quotient (Raven) tests. Patients were followed from 6 months to 3 years after the acute phase of the disease. There is a statistically significant difference between the D.Q of post-meningitic children and the D.Q. of non meningitic controls of the same social class and ages, when the onset of illness was before 30 months of age. No statistically significant correlation was found between the D.Q. and the patient's length of hospitalization or the first cerebrospinal fluid protein level. There is a possibility that significant correlation between the D.Q. and age at onset of illness may be observed by studying a larger number of patients. No statistically significant difference was found between the I.Q. of post-meningitic children and controls when the onset of illness was after age 4.

Prova de absorção de gordura em crianças.

To overcome the difficulties observed with fecal fat estimations, we studied fat absorption in 4 m to 12 years old children, assessing increments of serum triglycerides after administration of corn oil. Eighteen well-nourished children without gastrointestinal symptoms or parasites, 31 children with protein-calorie malnutrition (PCM), with or without protracted diarrhea and/or intestinal parasites and nine children with specific malabsorptive entities were studied. Serum triglycerides (TG) were measured before, 2 and 4 hours after the administration of 2 g/kg of corn oil per os. For control infants below 2 years no significant differences between the fasting level and those after 2 and 4 hours were observed. For children above this age significant absorption occurred by 2 hours but more intensively after 4 hours, an increment of TG above 35 mg% being considered normal. A good discrimination between TG increments of controls and malabsorptive children over 2 years was observed. In conclusion, the oral fat loading test, is applicable for children over 2 year of age. For infants below this age other schedules should be tested.

Contribuição para o estudo da proção cervical da veia facial de fetos, recém-nascidos e crianças.

In the study of cervical posterior of the facial vein of the foetus, newborns and children we injected in the veins of the head and neck of 15 corpses, rubber material (Xantopren and or Neoprene Latex). The results showed than the retromandibular and or the facial vein form a venous trunk in 83.3%, what finish always in the intern jugular vein or join the retromandibular vein and casually also with a posterior auricular vein originating the extern jugular vein (16.7%).

Estudio radiográfico do desenvolvimento da dentição permanente de crianças brasileiras com idade cronológica variando entre 84 e 131 meses.

With the help of orthopantomograms we analyse the tooth development beside body weight and height from Brazilian healthy boys and girls. So, their dental age were compared to their chronological age. The results of this investigation, according to the methodology employed, indicated that: 1. girls showed accelerated formation of permanent teeth and mean values of dental age higher than boys; 2. the mean values of dental age in girls were higher than their chronological age in all groups; 3. the teeth development stages were appropriate in assessment of the degree of physiological maturity of a growing child.

Interferentes eritrocitários e ambientais na anemia falciforme

Erythrocytes and environmental interferences on sickle cell anaemia Sickle cell anaemia runs na extremely variable clinical course At one end of spectrum, it is characterized by a crippling haemolitic anaemia, interspersed with severe exacerbations, or crises, yet it may be an extremely mild disorder, which is found only by chance on rotine haematological examination. The reasons are only partly understood for these remarkable differences in phenotypic expression of what appears to be the same genetic defect: they include the level of Hb Fetal, coinheritance of the alpha thalassaemia and of other genetic variantsthat has influence as genetic modulation in sickle cell anaemia. However, other genetics abnormalities of erythrocytes: G-6PD deficiency, spherocytosis and deficiencies of anti-oxidant enzymes(SOD, GPx and Catalase) probably interfereon the clinical course of sickle cell anaemia. The haplotypes of the chromosome (Bantu, Benin, Camaroon and Arab-Indian) bearing the sickle gene is associated with assorted haematological and clinical features that are likely, at least in part, to be mediated throgh effects on Hb Fetal concentration. Beyond these factors characterizes as erythrocytes interferents, there are the environmental interferents. Between environmental interferents become detached the socio-economic and cultural situation of each patient. These aspects have influence on the life of affected individuals including social interactions, family relations, peer interaction, intimate relationships, education, enployment, violence, spiritual attitudes and navigating complexities of the health care system, providers and their ancillary functions. As a result of this article it is proposed a protocol of laboratorial management of sickle cell syndrome with detach to sickle cell anaemia.

Manifestações otorrinolaringológicas em crianças com AIDS

Introduction: The study of otolaryngologic manifestations in children HIV + can lead to early diagnosis of AIDS, allowing specific treatment, responsible by reduced morbidity and mortality. Objectives: Detect the otolaryngologic manifestations in children with AIDS and alert to the importance of the early diagnosis. Study design: Clinical prospective. Material and method: We evaluated 22 children with AIDS assisted at Faculdade de Medicina de Botucatu (São Paulo, Brasil). The medical records were reviewed and the children were submitted to otolaryngologic and hearing acuity exams. Results: We evaluated 12 boys and 10 girls, whose ages ranged from 8 months to 12 years. In B and C clinical classification were included 18 children who were using anti-retroviral medicaments. Physical examination mainly indicated cervical lymphadenopathy (18 cases), paleness of the nasal mucous membrane with abundant mucous secretion over the nasal epithelium (15 cases) and retraction of tympanic membranes (seven cases). The main otolaryngologic diagnoses were: rhinosinusitis (16 cases), oral candidiasis (13 cases), inadequate eustachian tube function (seven cases) and recurrent tonsillar infections (six cases). Conductive hearing loss were detected in 4 children. No child presented sensorineural hearing loss. Conclusions: The main otolaryngologic manifestations presented by the children with HIV virus were rhinosinusitis, oral candidiasis, inadequate eustachian tube function and recurrent tonsillar infections. The allergic aspect of the nasal mucous membrane and the cervical lymphadenopathy were frequent signs and could alert the otolaryngologyst to AIDS during the exam.

Determinantes da evolução do peso e altura em crianças de 3 meses a 6 anos assistidas em creche: Análise por modelo linear não hierarquizado em ensaio quase-experimental

Objective. To assess factors determining growth in a group of children between 3 months and 6 years old enrolled in a public municipal (i.e., government-supported, not private) day-care center, in comparison to a group of children with similar characteristics but who were not enrolled in the center. Methods. A quasi-experimental study was designed to observe 444 children aged 3 to 72 months from a low-income neighborhood in the city of Sorocaba, in the state of São Paulo, Brazil. Two groups were studied: 164 children enrolled in a local municipal day-care center (intervention group) and 280 not receiving care at the center (nonintervention, comparison group) but instead being cared for at home. Both groups were seen four times over a period of 16 months. At each observation session, the children's weight and height were measured. Information was also collected on the mother's sociodemographic characteristics and the illnesses she had suffered as well as the child's weight and other health characteristics at birth, the child's illnesses in the 15 days before each observation, and any hospitalizations. Results. The children in both groups were from low-income families, with 65% of the families having an average monthly income below US$ 100; 80% of the mothers had received 8 years of schooling or less. Multivariate linear regression analysis showed that at the first observation (just before enrollment in the day-care center), birth weight was the only factor that explained the nutritional differences between the two groups. Subsequent analyses showed that being in day care was the factor that best explained the differences between the groups, especially in terms of the adequacy of weight for age, after controlling for birthweight, sex, age at the beginning of the study, and illnesses in the 15 days before an observation session. The nutritional impact of the intervention was significant as early as 3 months after being enrolled in day care. Conclusions. The nutritional benefits of the care provided at the center outweighed the negative effects sometimes seen in such centers, such as the greater morbidity that children in day-care centers often experience in comparison to children receiving care at home.

Afecções oculares em crianças de 2 a 8 anos da rede pública municipal de Piracicaba - SP

Study model: observacional, retrospective. Objective: to determine the frequence of the ametropic errors and other ocular problems in children with 2 to 8 year-old at Piracicaba - SP. Patients and Method: During the school year of 2000, 1001 children enrolled at the public schools of Piracicaba - SP, age ranged from 2 to 8 years old, were referred to complete ophthalmological exam. Visual acuity was previously determined using Snellen chart, applied by school teachers. Those children presenting visual acuity equal or less than 0.8, visual complaints or visual disorders were selected to appointment. Results: 51 children (5.09%) did not attended to examination. 950 children were submitted to complete ophthalmological exam. Ametropic errors were found 70.84% of the children. The most prevalent refractive errors were Hypermetropic Astigmatism (49.62%) and Hypermetropia (32,98%). Anisometropia was found in 1.78% children. Other ocular disabilities accounted for 10.21% of the examined children, such as strabismus (3.36%), eyelid changes, allergic conjunctivitis, congenital dacryostenosis, optic atrophy, corioretinitis and congenital glaucoma. Conclusion: The frequence of ocular problems observed let us to conclude the screening programs are valid surveys on decreasing rates of preventable blindness in our country.

A complexa fisiopatologia dos episódios vasooclusivos na anemia falciforme

Hemolytic anemia and vasoocclusion are the cardinal clinical features of sickle cell anemia. Vasoocclusion is a complex process involving not only the polymerization of deoxygenated sickle hemoglobin tetramers, but also interactions between sickle erythrocytes, vascular endothelium, platelets, leukocytes, and plasma proteins. The increased adherence of sickle erythrocytes to endothelium has been implicated as an early step in vasoocclusion. Other researchers have focused on leukocytes and platelets which might also contribute to disturbed blood flow. Microvascular occlusion results in acute painful crises, whereas macrovascular occlusion seems to be the cause of organ failure. The anemia results from the markedly shortened circulatory survival of sickle erythrocytes, together with a limited erythropoietic response. The erythropoiesis increases intensively, but it is not enough to balance the increased rate of erythrocytes destruction to maintain normal levels of total erythrocytes and hemoglobin concentrations; mainly by the low oxygen affinity of hemoglobin S and increased 2,3-Diphosphoglycerate. It is very difficult to separate processes leading to anemia or to vasoocclusion. Understanding the involvement of multiple blood componentes in vasoocclusion may elucidate the clinical manifestations and complications of sickle cell anemia, and may give new insights into the preventive and curative therapy.

Inquérito sobre a qualidade de vida relacionada à saúde em crianças e adolescentes portadores de artrites idiopáticas juvenis

Objective: to study the impact of chronic arthritis on health related quality of life by means of two self-reported tools: the parents' version of the Childhood Health Assessment Questionnaire (CHAQ) and the Childhood Health Questionnaire PF50® (CHQ). Methods: both tools were filled in after proper instructions by 36 parents, during 1-2 clinic visits. The Disability Index (CHAQ) and the Physical and Psychosocial scores (CHQ) were compared to the core set of outcome measures, namely 1) physician's global assessment, 2) parents' global assessment, both scored by 10 cm visual analogue scale, 3) number of joints with active arthritis, 4) number of joints with limited range of motion, 5) erythrocyte sedimentation rate. Results: there was significant difference for all measures of disease activity, being higher in the polyarticular as compared to oligoarticular except for erythrocyte sedimentation rate, parents' global assessment, and psychosocial score. This leads to different parents' perceptions of disease activity and outcome. The responsiveness of the outcome measures during two follow-up visits of patients receiving active treatment indicated better responsiveness of physicians' global assessment among the subjective measures, and intermediate responsiveness of the self-reported measures in comparison to the number of active and limited joints, and erythrocyte sedimentation rate. Conclusions: the responsiveness of two health related quality of life tools indicates their relative sensitivity for assessing clinical improvement during active treatment in Juvenile Idiopathic Arthritis patients.
