Cervicovaginal aerobic microflora of women with spontaneous abortion or preterm delivery in Araraquara-Brazil

Rotina bacteriológica do conteúdo vaginal e cervical de 22 mulheres com histórico de aborto recente ou ruptura precoce das membranas foi realizada. Chlamydia trachomatis, Streptococcus pyogenes, Streptococcus agalactiae, Candida sp e Gardnerella vaginalis foram isolados em 54,5% (12) das pacientes. Apesar de Ureaplasma urealyticum ter sido frequentemente encontrado (45,5%), somente em 5 das 22 mulheres foi o único microrganismo presente nos materiais analisados. Esses resultados chamam a atenção para a importância de investigação quantitativa bem como qualitativa da microbiota genital em gestantes, tendo em vista ter consequências na gestação.

Alterações orais em crianças prematuras e de baixo peso ao nascer: a importância da relação entre pediatras e odontopediatras

OBJETIVO: Apresentar uma revisão de literatura sobre as alterações orais em crianças prematuras e de baixo peso ao nascer. FONTES DE DADOS: Foram selecionados artigos em inglês e português, desde 1976 até 2009, pesquisados no PubMed, Lilacs e na Bibliografia Brasileira de Odontologia (BBO), além de livros e consensos nacionais e internacionais. As palavras-chave utilizadas foram: prematuro, recém-nascido de baixo peso, cárie dentária, hipoplasia do esmalte dentário, manifestações bucais e dentição primária. Selecionaram-se artigos avaliando incidência, prevalência e etiologia das alterações orais, além de revisões de literatura e relatos de casos clínicos. SÍNTESE DOS DADOS: As alterações orais mais comuns em crianças prematuras e de baixo peso ao nascer são os defeitos no esmalte dentário (hipoplasias e hipocalcificações), a predisposição ao desenvolvimento de lesões de cárie dentária, as alterações na cronologia de erupção dentária e as alterações no palato com consequente aparecimento de maloclusão. Outras alterações também são relatadas, como diferenças nas dimensões das coroas dentárias e na espessura e porosidade do esmalte dentário. A interação entre pediatras e odontopediatras é fundamental no manejo dessas crianças. CONCLUSÕES: O conhecimento das alterações orais em crianças pré-termo e de baixo peso ao nascer por parte dos pediatras e odontopediatras favorece a atuação multidisciplinar com o objetivo de educar, prevenir e atenuar as possíveis mudanças físicas e dentárias nessas crianças.

Métodos de alimentação alternativos para recém-nascidos prematuros

OBJETIVO: Apresentar revisão de literatura sobre o uso do copo/xícara como método alternativo de alimentação para recém-nascidos prematuros e verificar se há consenso sobre sua indicação para essa população. FONTES DE DADOS: Revisão de literatura narrativa, tendo sido selecionados artigos nas bases de dados Medline, Lilacs, SciELO e Cochrane, independentemente do ano, usando descritores específicos: alimentação artificial, recém-nascido prematuro, aleitamento materno, métodos de alimentação. SÍNTESE DOS DADOS: Apesar de alguns estudos afirmarem que o método do copo/xícara é eficaz e seguro para alimentar recém-nascidos pré-termo e a termo, tais estudos não avaliam de forma objetiva o efeito do método sobre a deglutição desses pacientes. CONCLUSÕES: Verificou-se não haver consenso na literatura quanto à complementação da alimentação de recém-nascidos prematuros por meio do copo/xícara. Estudos controlados devem ser realizados com a finalidade de rever riscos e benefícios do uso de métodos alternativos na alimentação do recém-nascido prematuro.

Enamel Defects in Maxillary Central Incisors of Infants With Unilateral Cleft Lip

Objective: To evaluate the presence of enamel alterations in deciduous maxillary central incisors of infants with unilateral cleft lip and alveolar ridge, with or without cleft palate, and to compare the occurrence and location of these alterations between the central incisor adjacent to the cleft and the contralateral incisor.Design: Intraoral clinical examination was performed after tooth cleaning and drying by a single examiner with the aid of a dental mirror, dental probe, and artificial light, with the child positioned on a dental chair. The defects were recorded in a standardized manner according to the criteria of the Modified Developmental Defects of Enamel Index.Setting: Hospital for Rehabilitation of Craniofacial Anomalies (HRAC) at Bauru, São Paulo, Brazil.Patients: One hundred one infants were evaluated. All were white, of both genders, aged 12 to 36 months and had at least two thirds of the crowns of maxillary incisors erupted.Results: Demarcated opacity was the most common defect at both cleft and noncleft sides, followed by diffuse opacity. The occurrence of hypoplasia at the cleft side was 11.8%. Most defects affected less than one third of the crown.Conclusion: The occurrence of enamel defects in deciduous maxillary central incisors of patients with unilateral cleft lip was 42.6%, mainly affecting the cleft side as to both number and severity.

Relação do peso de recém-nascidos e placentas. Estudo em recém-nascidos de termo, pré-termo e pós-termo, de pesos adequado, baixo e grande para a idade gestacional

Birth weight and placental weight of 566 newborns were determined. The newborns were classified by birth weight and gestational age in seven groups: term, preterm and postterm newborns with weight appropriate for gestational age; term and postterm newborns small for gestational age; term and preterm newborns large for gestational age. The differences in the mean placental weight in the preterm, term and postterm newborns with weight appropriate for gestational age were not significant. After 34 weeks of gestation there was little increase in placental weight. The mean placental weight of newborns large for gestational age was significantly different from that of term newborns appropriate for gestational age. In the term and postterm newborns small for gestational age the mean placental weight was significantly different from term and postterm newborns appropriate for gestational age. These findings suggest that newborns with an appropriate intrauterine growth have little increase in placental weight in the gestational period. Gestational age is not an important factor in determining placental weight in this period. Nutrition is important for placental growth-retarded infants have small placentas and large-for-date infants have large placental weight.

Nutritional management and weight changes during hospitalization of Brazilian infants with diarrhoea: Primary reliance on oral feeding or continuous nasogastric drip with locally made, modulated minced chicken formula

The nutritional management of infants admitted with diarrhoea to the University Hospital of Botucatu includes a change from bolus feeding of a modulated minced-chicken formula to a continuous nasogastric drip (NGD) feeding, whenever the required calorie intake is not achieved or the diarrhoea does not subside. To evaluate this approach, the clinical course and weight changes of 63 children, aged 1-20 months, were reviewed; most (81 per cent) were below the third percentile for weight at admission and 76 per cent had a total duration of diarrhoea ≥10 days. Associated infections, mainly systemic, were present at or after admission in 70 per cent of them. Twenty-five survivors needed nutritional support (NS), predominantly NGD, for a median duration of 30 per cent of their admission time, and were compared to 31 survivors managed without NS. Those who necessitated NS lost weight for a significantly longer median time (12x4 days, p<0.005), but their total weight loss was similar (5x4 per cent) as well as diarrhoea's duration (8x7 days). There was a tendency for a longer hospitalization (21x16 days 0.05infants (11 per cent) died, most of overwhelming infection, and presented a high total weight loss, albeit receiving NS for 71 per cent of their admission's time. It was concluded that feeding diarrhoeic infants with a NGD when necessary, possibly prevented a greater nutritional insult for the survivors. The NGD can be safely employed and should be valued, provided weight losses are carefully monitored in order to detect infants at highest risk.

Gut intraepithelial lymphocyte counts in neonates, infants and children

Intraepithelial lymphocyte (IEL) counts were histologically assessed in the jejunum, ileum and appendix of 39 neonates (0-28 days), 32 infants (1-9 months) and 13 children (1-9 years). Small intestinal mucosa samples were obtained from 73 autopsies, and from 8 surgical and 3 aspirative biopsies. IEL counts of specimens from the jejunum, ileum and appendix gave similar results in the same patient. The number of IEL counts was significantly lower in neonates for all three segments. The difference between infants and children was more marked in the jejunum than in the ileum, although this was not significant. In the appendix, there was no difference between the different age groups. Our results indicate that postnatal expansion of IEL occurs homogeneously along the gut after the neonatal period.

Visual information and body sway coupling in infants during sitting acquisition

The purpose of this study was to examine if there is any developmental change in the coupling between visual information and trunk sway in infants as they acquire the sitting position. Twenty-four infants distributed in four groups (6-, 7-, 8-, and 9-month-old) were sat inside a moving room that oscillated back and forward at frequencies of 0.2 and 0.5 Hz. The results revealed that trunk sway matched to the moving room at both frequencies but did not differ among the four age groups. Coherence and gain revealed that the coupling was weaker at 0.2 than at 0.5 Hz. Relative phase showed that at 0.2 Hz, infants were swaying with no lag but at 0.5 Hz they were lagging the room. These results showed that the coupling between visual information and trunk sway in infants varies with the visual stimulus but does not change as infants acquire the sitting position. © 2001 Elsevier B.V.

Influence of dental care for infants on caries prevalence: A comparative study

Purpose: The influence of early dental care on the prevalence of dental caries was determined in children ages 35 to 40 months divided into 2 groups of 160 children each, with 1 group participating in a dental care program from the first year of life to the time of the study, while the other group did not receive any dental care. Methods: The clinical conditions considered for the evaluation were: sound teeth, enamel caries without cavitation, enamel caries with cavitation, and dentinal caries. The proportion and chi-square tests were used for statistical analysis with the level of significance set at 5%. Results: A significant difference regarding the presence of dental caries, especially in the number of children presenting enamel caries with cavitation (P<.0001), was observed between the 2 groups. The number of children with enamel caries without cavitation and dentinal caries was similar for the 2 groups. Conclusions: Considering the aspect of dental caries prevention, the authors concluded that children in the age range of 3 to 4 years who received early dental care showed better oral conditions.

Systemic and local teething disturbances: Prevalence in a clinic for infants

The aim of this study was to present data as reported by parents on primary tooth eruption and the occurrence of local and systemic manifestations in children ages 0 to 3 years seen at the baby clinic of the Araçatuba Dental School, UNESP, São Paulo, Brazil. Data from 1,813 records were analyzed, yielding 1,165 records suitable for review. Some type of local and/or systemic manifestation during primary tooth eruption was reported for 95% (1,129) children studied. The predominant manifestation was gingival irritation (85%), while the least frequent symptom (26%) was a runny nose.
