Evaluation of physiological parameters before and after respiratory physiotherapy in newborns with acute viral bronchiolitis.

Background: Acute viral bronchiolitis is a respiratory disease with high morbidity that affects newborn in the first two years of life. Its treatment with physiotherapy has been highlighted as an important tool, however, there is no consensus regarding its effects on patients improvement. We aimed to evaluate the physiological parameters before and after the procedure respiratory therapy in newborn with acute viral bronchiolitis.

Peak expiratory flow values are higher in older and taller healthy male children: an observational study.

Purpose: Peak expiratory flow (PEF) was measured in healthy children aged five to ten years in order to provide baseline values and to determine correlations between PEF and factors such as gender, age and type of school.

Methods: After the Ethical Committee of Research in Human of the School of Medicine of ABC - FMABC approval, PEF and height were measured in 1942 children between five and ten years old from nine public schools and nine private schools throughout São Bernardo do Campo City. PEF was measured using the Mini-Wright Peak Flow Meter (Clement Clarke International Ltd.

[Validation of birth certificates based on data from a case-control study].

The information recorded on birth certificates was validated with data from a perinatal mortality case-control study, obtained from home interviews of mothers and hospital records for cases (early neonatal deaths) and controls. Sensitivity, specificity, and concordance were calculated for all variables and their estimated and real prevalence. The completeness of birth certificates was lowest for mother's parity and presence of congenital anomalies (records without information range from 23% to 31% for cases and controls).

[Risks associated with the weaning process in children born in a university hospital: a prospective cohort in the first year of life, São Paulo, 1998-1999].

This study describes breastfeeding practices with children born in a university hospital in the city of S o Paulo, Brazil, and identifies factors associated with duration of breastfeeding and exclusive breastfeeding. A cohort of 506 children was identified; of these, it was possible to analyze information on feeding practices for 450 infants at least until the second month of life. Daily information on infant feeding was recorded by mothers in a food frequency questionnaire.

[An analysis of the implementation of Committees on Maternal Mortality in Brazil: a case study of the São Paulo State Committee].

The precarious available information and difficulties in obtaining consistent data on maternal deaths in Brazil raise doubts as to the reliability of official statistics. The Committees on Maternal Mortality are considered an important strategy for overcoming these difficulties. This article discusses certain aspects of the Committees' performance, based on the case of the State of S o Paulo, demonstrating the Committee's role as a policy and advocacy instrument, thus going beyond merely an epidemiological surveillance strategy.

[Asthma mortality in the city of São Paulo, Brazil].

Objective: To quantify and compare asthma mortality rates as the main cause of death, taking into consideration the following variables: sex, age and seasonality.

Methods: Data was collected from all death certificates coded 493 of people aged 5 to 34 years in the periods of 1983-5 and 1993-5 in the city of São Paulo, SP, Brazil. Data analysis was performed by directly comparing death rates and identifying the odds ratio trend and directly comparing the numbers of asthma deaths.
