Pet dogs and child physical activity: the role of child-dog attachment.

BACKGROUND: Dog ownership has been associated with increased physical activity in children which in turn may mitigate childhood obesity. OBJECTIVE: To measure the association between child-dog attachment and child physical activity and screen time. METHODS: Cross-sectional study including 370 children (ages 4-10) who had pet dogs in the home. Parents completed the DartScreen, a web-based screener, before a well-child visit. Screener domains included child body mass index (BMI), physical activity, screen time and dog-related questions. The Companion Animal Bonding Scale (CABS) was used to measure child attachment to the dog. Clinic nurses weighed and measured the children. Associations between CABS, BMI z-score, screen time and physical activity were estimated. RESULTS: CABS was strongly associated with time spent being active with the dog (F = 22.81, p < 0.0001), but not with BMI z-score or screen time. CONCLUSIONS: A higher level of child attachment to a pet dog is associated with increased child physical activity.

Bronchodilators for bronchiolitis.

BACKGROUND: Bronchiolitis is an acute, highly infectious lower respiratory tract infection. Bronchodilators are commonly used in the management of bronchiolitis in North America but not in the United Kingdom. OBJECTIVES: The objective of this review was to assess the effects of bronchodilators on clinical outcomes in infants with acute bronchiolitis. SEARCH STRATEGY: In this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library, Issue 1, 2006), MEDLINE (1966 to October 2005), EMBASE (2003 to September 2005) and the reference lists of articles. The files of one author (AG) were also reviewed. SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing bronchodilators (other than epinephrine) with placebo in the treatment of bronchiolitis. DATA COLLECTION AND ANALYSIS: For this updated review, one author assessed trial quality and extracted data. Unpublished data were requested from study authors when necessary. MAIN RESULTS: Twenty-two clinical trials with 1428 infants with bronchiolitis were included in this review. In eight trials, with 468 infants, there was no improvement in clinical score for 43% of those treated with bronchodilators compared to 57% of those treated with placebo (odds ratio (OR) for no improvement 0.45, 95% confidence interval (CI) 0.15 to 1.29). There was a statistically significant but clinically modest improvement in the overall average clinical score (standardized mean difference (SMD) -0.48, 95% CI -0.62 to -0.33). However there was no statistically significant improvement in oxygenation overall (weighted mean difference (WMD) -0.57, 95% CI -1.17 to 0.03). Subgroup analyses showed a slightly greater effect size in outpatient studies, where there were shorter follow up durations, than in inpatient studies for both oximetry (outpatients WMD -0.84, 95% CI -1.59 to -0.10 versus inpatients WMD -0.25, 95% CI -1.18 to 0.67) and average clinical score (outpatients SMD -0.68, 95% CI -0.87 to -0.49 versus inpatients SMD -0.23, 95% CI -0.44 to -0.01). Bronchodilator recipients showed no improvement in the rate of hospital admission after treatment as outpatients (18% versus 26%, OR 0.70, 95% CI 0.36 to 1.35) or duration of hospitalization for inpatients (WMD 0.02, 95% CI -0.32 to 0.36). The inclusion of studies that enrolled infants with recurrent wheezing may have biased the results in favor of bronchodilators. AUTHORS' CONCLUSIONS: Bronchodilators produce small short-term improvements in clinical scores. This small benefit must be weighed against the costs and adverse effects of these agents.

Changes in health care providers' knowledge, attitudes, beliefs, and behaviors regarding domestic violence, following a multifaceted intervention.

PURPOSE: To improve domestic violence (DV) identification, management, and referral in a not-for-profit rural health network, training for health care professionals was implemented using a train-the-trainer approach, two one-hour training sessions, and dissemination of a clinical protocol. The multifaceted approach also involved modifications of emergency department medical records, distribution of office enablers, and a local public health campaign. The authors measured the effectiveness of this campaign. METHODS: After implementation of a multifaceted training and public awareness campaign, a questionnaire designed by the Centers for Disease Control to measure knowledge, attitudes, beliefs, and intended behaviors (KABB) of health care providers relative to DV was administered to 380 health care professionals in the fall of 1997, with a follow-up survey completed after the intervention in the fall of 1999. RESULTS: The response rates for the pre- and post-intervention surveys were 67% (n = 380) and 56% (n = 273), respectively. Two scales were correlated in the base-line survey: self-efficacy (related to DV response) and familiarity with referral resources. Reporting of victim identification in the preceding year increased from 36% to 39%. Those with training were more likely to have identified a victim within the year (OR = 2.86; 95% CI, 1.73-4.74). Among the 232 respondents with complete data, multiple analysis of variance demonstrated statistically significant overall improvement across all scales. Nine of the 13 KABB scales revealed significant increases from pre- to posttest and included: screening, workplace resources, making referrals, provider self-efficacy, victim autonomy, victim understanding, legal requirements, staff preparation, and too busy/can't help. CONCLUSION: A comprehensive training program for health care providers can increase their self-efficacy in responding to DV victims.

Impact of a rural domestic violence prevention campaign.

Domestic violence is a prevalent health problem that in rural areas is further complicated by limited services, social isolation and the lack of privacy. Little is known about the impact of public health education on awareness, attitudes and behavior of the general public regarding domestic violence. This study sought to measure change in societal attitudes and behavioral intention in response to a seven-month public health education campaign targeting domestic violence in a rural county. From October 1998 to April 1999, the campaign used radio advertisements, posters, mailings to libraries and clergy, printed media articles, printed advertisements and health facility modifications. A random-digit-dialing telephone survey was used to evaluate attitudinal and behavioral changes in the intervention and comparison counties before and after the campaign. The response rates for the pre- (n =378) and postcampaign (n=633) surveys were 73 percent and 65 percent, respectively. Statistically significant increases in slogan and advertising recognition occurred in the intervention county (P=0.03), particularly among men recalling the campaign slogan (P=0.006). In a vignette regarding actions to be taken if the neighbor next door was abusing a partner, significant increases occurred in the intervention county in the percentage of respondents who thought that most people would talk to the victim (P=0.04), consult with friends (P=0.002) or talk to a doctor (P=0.004). Domestic violence agency hotline calls in the intervention county doubled following the campaign. Local public health education campaigns in a rural setting may be a valuable adjunct to national efforts, especially in reaching men.

Bronchodilators for bronchiolitis.

OBJECTIVES: Bronchiolitis is an acute, highly communicable lower respiratory tract infection. Bronchodilators are commonly used in the management of bronchiolitis in North America, but not in the United Kingdom. The objective of this review was to assess the effects of bronchodilators for bronchiolitis. SEARCH STRATEGY: We searched MEDLINE, EMBASE, Reference Update, reference lists of articles, and the files of two of the authors up to June 1998. SELECTION CRITERIA: Randomised trials comparing bronchodilators with placebo in the treatment of bronchiolitis. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Unpublished data were requested from authors when necessary. MAIN RESULTS: In eight trials with 394 children, 46% demonstrated an improved clinical score with bronchodilators compared to 75% with placebo (odds ratio for no improvement 0.29, 95% confidence interval 0.19 to 0.45). However, the inclusion of studies that enrolled people with recurrent wheezes may have biased these results in favour of bronchodilators. Bronchodilator recipients did not show improvement in measures of oxygenation, the rate of hospitalisation (18% versus 26%, odds ratio 0.70, 95% confidence interval 0.36 to 1.35) or duration of hospitalisation (weighted mean difference 0.12, 95% confidence interval -0.3 to 0.5). REVIEWER'S CONCLUSIONS: Bronchodilators produce modest short-term improvement in clinical scores. This small benefit must be weighed against the costs of these agents.

Population-based study of the adequacy of well-child care services: a rural county's report card.

OBJECTIVE: To determine the adequacy of well-child care services using a population-based study. DESIGN: The medical records of all county providers and the immunization records at the local health department were reviewed. A county birth cohort, identified using electronic birth certificates, was compared with those who migrated into the area (hereafter, in-migrants). SETTING: All primary care sites (private, network, etc) in a rural county. PATIENTS: Two-year-old children born between May 31, 1993, and May 30, 1994. MAIN OUTCOME MEASURES: Immunization rates and preventive screenings. RESULTS: A total of 674 medical records were reviewed. Of these, 377 (56%) belonged to a county birth cohort and 297 (44%) were in-migrants. Medical records of 64% of the birth cohort were reviewed. Among all 2-year-olds, 80% received 4 doses of diphtheria and tetanus toxoids and pertussis vaccine; 89%, 3 doses of Haemophilus influenzae type b (Hib); 75%, 4 doses of Hib; 77%, 3 doses of hepatitis B vaccine; 85%, measles-mumps-rubella vaccine; 85%, 3 doses of oral poliovirus vaccine; 17%, varicella live virus vaccine (Varivax). The 4:3:1 rate was 75% at age 2 years. Sixty-eight percent had had 1 hematocrit, 74% had 1 lead screening test, and 43% had 2 lead screening tests. A total of 64% had had 6 well-child visits and 30% had had 9. The mean number of weights and heights measured was 4.8 and 4.5, respectively, at age 1 year and 7.3 and 6.8, respectively, at age 2 years. The birth cohort had notably higher rates of documented immunization and preventive screening than in-migrants. CONCLUSIONS: This study demonstrated immunization coverage at or below the national average, and well-child care service provisions below American Academy of Pediatrics standards at a county level. This study enabled individual primary care sites to assess their well-child care provision and provided a useful baseline for targeting the improvement of well-child care services in the county.

Efficacy of bronchodilator therapy in bronchiolitis. A meta-analysis.

OBJECTIVE: To determine if bronchodilators are efficacious in treating bronchiolitis. DATA SOURCES: A search of bibliographic databases (MEDLINE, Excerpta Medica, and Reference Update) for bronchiolitis and albuterol or ipratropium bromide, or adrenergic agents or bronchodilator agents. Reference lists were also used. STUDY SELECTION: Randomized, placebo-controlled trials of bronchodilator treatment in bronchiolitis were selected by 2 investigators. Fifteen of 89 identified publications met the selection criteria. DATA EXTRACTION: Investigators independently abstracted data for 3 outcomes: clinical score, oxygen saturation, and hospitalization. Clinical score was measured as a dichotomous variable (score +/- improved) or continuous variable (average score). DATA SYNTHESIS: For primary analysis, data were pooled from 8 trials of children with first-time wheezing. The effect size for average score was -0.32 (95% confidence interval [CI], -0.54 to -0.11; P < .01), favoring treatment; the relative risk for score +/- improved was 0.76 (95% CI, 0.60 to 0.95; P = .02), favoring treatment. Bronchodilators had no effect on hospitalization (relative risk, 0.85; 95% CI, 0.47 to 1.53; P = .58), but co-interventions may have been administered prior to this outcome. The results for oxygen saturation were too varied to allow pooling of the results. Secondary analyses were performed on 4 outpatient trials of children with first-time wheezing, 7 trials in which only nebulized beta-agonists were used, and on all 15 trials identified. The results were similar, but the data varied more. CONCLUSION: Bronchodilators produce modest short-term improvement in clinical features of mild or moderately severe bronchiolitis.

Maternal reporting of acute respiratory infection in Egypt.

BACKGROUND: Acute respiratory infection (ARI) is a major cause of childhood morbidity and mortality in developing countries. Community surveys are used to determine the proportion of children with ARI for whom care is sought by questioning mothers about the signs and symptoms of illness episodes. The validity of this approach has been studied infrequently. METHODS: We evaluated maternal reporting of signs and symptoms 2 and 4 weeks after diagnosis among 271 Egyptian children < 5 years old. Children with ARI were evaluated by physical examination, chest radiography, and pulse oximetry, and were alternately assigned for a maternal interview about the episode 14 or 28 days later. RESULTS: For radiographically-defined acute lower respiratory infection (ALRI), the sensitivity of several symptoms for combined open- and close-ended questions was relatively high: nahagan (deep or rapid breathing) (80%), nafas sarie (fast breathing) (66%), and kharfasha (coarse breath sounds) (63%). The specificity of these terms was 50-68%. The specificity was inversely related to the follow-up time. No term provided both a sensitivity and specificity of > 50% at day 28 across the radiographically, clinically- and pulse oximetry-based definitions of ALRI. Spontaneously mentioned karshet nafas (difficult or rapid breathing) at 14 days had a specificity and sensitivity for radiographic ALRI of 87% and 41%, respectively, suggesting that this term is a good choice for community surveys. CONCLUSIONS: Maternal reporting of ARI symptoms is non-specific 2 and 4 weeks after diagnosis but may be useful for monitoring trends in the proportion of children with pneumonia who receive medical care. To maximize specificity, ARI programmes should generally use a recall period of 2 weeks.

PIP: Acute respiratory infection (ARI) is a major cause of childhood morbidity and mortality in developing countries. Community surveys are used to determine the proportion of children with ARI for whom care is sought by questioning mothers about the signs and symptoms of illness episodes. The validity of this approach has been studied infrequently. Maternal reporting of signs and symptoms was evaluated 2 and 4 weeks after diagnosis among 271 Egyptian children 5 years old selected from a prospective study of the signs and symptoms of pneumonia in Ismailia and Assiut. Children with ARI were evaluated by physical examination, chest radiography, and pulse oximetry, and were alternately assigned for a maternal interview about the episode 14 or 28 days later. Nahagan (deep or rapid breathing), yenet (grunting), and karshet nafas (difficult or rapid breathing) were the most frequently mentioned terms reported by 49%, 28%, and 31% of the mothers, respectively. For radiographically-defined acute lower respiratory infection (ALRI), the sensitivity of several symptoms for combined open- and close-ended questions was relatively high: nahagan (80%), nafas sarie (fast breathing) (66%), and kharfasha (coarse breath sounds) (63%). The specificity of these terms was 50-68%. In general, the sensitivity was greater for 14- or 28-day recall than day 0, but the specificity was inversely related to the follow-up time. No term provided both a sensitivity and specificity of 50% at day 28 across the radiographically, clinically- and pulse oximetry-based definitions of ALRI. Spontaneously mentioned karshet nafas (difficult or rapid breathing) at 14 days had a specificity and sensitivity for radiographic ALRI of 87% and 41%, respectively, suggesting that this term is a good choice for community surveys. Maternal reporting of ARI symptoms is non-specific 2 and 4 weeks after diagnosis but may be useful for monitoring trends in the proportion of children with pneumonia who receive medical care. To maximize specificity, ARI programs should generally use a recall period of 2 weeks.

Clinical trial of vitamin A as adjuvant treatment for lower respiratory tract infections.

OBJECTIVE: To test the efficacy of a high dose of vitamin A as adjuvant treatment for radiographically confirmed cases of acute lower respiratory tract infection (ALRI). DESIGN: Randomized, double-masked, placebo-controlled clinical trial. SETTING: Two large urban hospitals in Guatemala City. PATIENTS: Sequential sample of 263 children aged 3 to 48 months, identified in the emergency departments and admitted to the hospital. INTERVENTIONS: Vitamin A (100,000 IU for children less than 1 year of age, and 200,000 IU for older children) or placebo in addition to standard treatment for ALRI which included antibiotics, oxygen, bronchodilators, and intravenously administered solutions. MEASUREMENTS AND MAIN RESULTS: The children were assessed every 8 hours. There were neither statistically nor clinically significant differences by treatment group in the rate of normalization in respiratory rate, oxygen saturation, temperature, or clinical score. Duration of hospitalization was not different by treatment group. Adverse outcomes (mechanical ventilation, prolonged hospitalization, readmission or transfer, and death) were equally distributed between the two groups. CONCLUSIONS: Treatment with high doses of vitamin A over and above standard care for infants and children with non-measles-related ALRI is not efficacious for the current episode. Additional trials among populations in which vitamin A deficiency is more prevalent and severe should be considered.

PIP: During October 1991 to March 1993, in Guatemala, clinical researchers conducted a randomized, double-blind, placebo-controlled clinical trial of 263 pediatric patients aged 3-48 months at the Hospital Roosevelt and the Guatemalteco Social Security Institute Hospital, both in Guatemala City. They aimed to determine the efficacy of a high dose of vitamin A (100,000 IU for children under 1 year of age and 200,000 IU for older children) as adjuvant treatment for radiographically confirmed cases of non-measles-related acute lower respiratory tract infection (ALRI). All the children received standard treatment for ALRI (antibiotics, oxygen, bronchodilators, and intravenously administered solutions). 132 children also received vitamin A and 131 received a placebo. Clinicians evaluated the childrens' condition every 8 hours. The two groups were essentially the same in duration of hospitalization; the rate of normalization in the respiratory rate, oxygen saturation, temperature, and clinical score; and adverse outcomes (mechanical ventilation, prolonged hospitalization, readmission or transfer, and death). These findings indicate that high doses of vitamin A in addition to standard treatment for non-measles-related ALRI lack efficacy for the current ALRI episode.

Diverting managed care Medicaid patients from pediatric emergency department use.

OBJECTIVE: To evaluate the health outcomes of managed care Medicaid children with non-emergent conditions who were not authorized to be seen in the Pediatric Emergency Department (PED) by their primary care provider. DESIGN: Consecutive case surveillance from 6/29/92 to 2/2/93. SETTING: University based PED (17,500 visits/year) in inner city Baltimore. PARTICIPANTS: Cases were MAC children denied authorization to be seen for non-emergent conditions in the PED. Age and complaint matched MAC children were selected from the university based Pediatric Ambulatory Center (PAC) and from non-emergent PED visits (PED-seen) in order to compare utilization rates after denial. INTERVENTION: The Maryland Access to Care (MAC) Medicaid program (started in 12/91) emphasizes primary care and appropriate health care utilization by incorporating the following elements of managed care: assignment to primary care provider, gatekeeping, mandatory enrollment and fee for service. METHODS: Consecutive case surveillance from 6/29/92 to 2/2/93 was used to evaluate the health outcomes of MAC children denied authorization for non-emergent care in a university based PED. One week following denial, a pediatric nurse practitioner contacted the patient's caretaker and the MAC provider to ascertain health outcome. Medicaid claims data was used to compare the six month health care utilization of the denied group to age and complaint matched children seen in the PED (PED-seen) or in a primary care clinic (PAC). RESULTS: 216 MAC patients were not authorized for a PED visit by their MAC providers. 123 (57%) saw their MAC provider within one week of the denied PED visit. 40 (18%) were not seen because their presenting complaint had resolved completely. No adverse health outcomes occurred because of delay in health care delivery. The subsequent ER utilization rate of the denied group was the same as the PED-seen comparison group, and significantly higher than that of the PAC group (P = .002). The denied group was hospitalized at a significantly higher rate relative to these comparison groups (P = .003). CONCLUSIONS: Diverting Medicaid children classified as non-emergent in an ER to their MAC providers can be a safe practice short-term. However, denial of a PED visit has no impact on subsequent ER utilization by Medicaid participants and may be associated with higher hospitalization rate. Gatekeeping in this setting does not necessarily change the health care seeking behavior of these patients.

Correcting respiratory rate for the presence of fever.

This study defines what degree of respiratory rate (RR) elevation can be attributed to fever using a double blind randomized pre- and post-acetaminophen comparison of vital signs of febrile children presenting to an outpatient clinic. Inclusion criteria were aged between 6 weeks and 24 months, fever between 38.5 and 40.1 degrees C, no serious illness such as sepsis, and no recent receipt of antipyretics or antibiotics. RRs counted over 1 min and rectal temperatures were recorded by a trained observer before, and 1 and 1.5 hours (hr) after receipt of 10-15 mg/kg/dose of either acetaminophen (A) or placebo (P). Randomization produced groups A (n = 54), and P (n = 50) with similar mean age (12.3 vs 12.8 mo.), gender distribution (57 vs 54% female), baseline temperature (39.1 vs 39.1 degrees C), baseline RR (44 vs 45), and hours of fever prior to visit (42 vs 37 hr). The most common diagnoses were otitis media (49%), viral syndrome (18%), upper respiratory infection (16%) or gastroenteritis (7%). The mean temperature decrement of group A was 0.4 degrees C at 1 hr and 0.9 degrees C at 1.5 hr compared to slight increases in fever of 0.3 degrees C at 1 hr and 1.5 hr in group P. Significant decreases in RR occurred in group A compared to group P at 1 hr (7.0 vs 1.9, p = 0.009) and 1.5 hr (10.8 vs 4.0, p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Efficacy of albuterol in the management of bronchiolitis.

OBJECTIVE: To examine the efficacy of albuterol (0.15 mg/kg per dose) in the management of bronchiolitis. DESIGN: Randomized, double-blind, placebo-controlled outpatient clinical trial utilizing four study groups: neubulized albuterol, nebulized saline, oral albuterol, and oral placebo. SETTING: Pediatric emergency department and outpatient clinic at University of Maryland in Baltimore. PATIENTS: Eighty-eight infants (median age 5.5 months) being treated for their first episode of wheezing were randomly assigned to nebulized albuterol (n = 22), nebulized saline (n = 23), oral albuterol (n = 19), oral placebo (n = 24). INTERVENTIONS: The nebulized groups received two nebulizations 30 minutes apart, whereas the oral groups received one oral dose. MAIN OUTCOME MEASURES: Respiratory and heart rates, clinical score, oxygen saturation (Spo2), and the infant's state, ie, asleep, awake, or feeding, were recorded at baseline and at 30 and 60 minutes after treatment. RESULTS: Randomization produced equivalent groups in terms of demographics and baseline measures. There were no statistically significant differences in any outcomes among the four treatments, except for oral albuterol, which produced an increase in heart rate (15 beats per minute, P = .005). No differences in the need for additional treatment or hospitalization were observed. Change in the state of the infant during the trial had significant effects on respiratory rate and clinical score. CONCLUSIONS: Albuterol is as effective as oral placebo in the management of bronchiolitis. Past studies supporting the use of albuterol did not control for effects of change in state of the infant and did not use a truly inactive placebo group. This study underscores the importance of these design components in measuring the efficacy of albuterol in infants.

Oral versus nebulized albuterol in the management of bronchiolitis in Egypt.

The efficacy of albuterol in the management of infants with first-time wheezing is controversial. This double-blind, placebo-controlled trial involved 128 Egyptian infants with first-time wheezing (mean age 5.9 months) who were randomly separated into four equivalent therapy groups: nebulized albuterol, nebulized saline solution, orally administered albuterol, and orally administered placebo. The nebulized therapy groups received two treatments 30 minutes apart; the oral therapy groups received one treatment. In addition, 41 infants with recurrent wheezing comprised an open-label control group who received two albuterol nebulizations. Chest radiographs, leukocyte counts, blood culture specimens, and nasal aspirate for viral antigen detection were obtained to confirm the clinical diagnosis of viral bronchiolitis. Respiratory and heart rates, clinical score, and oxygen saturation were recorded at baseline and 30 and 60 minutes after treatment. There was no difference among the four randomized groups in any of the outcomes except for an increase in heart rate of 10 beats/min in the nebulized albuterol group compared with a decrease in heart rate of 8 beats/min in the oral placebo group. No differences in the need for additional treatment were observed. Nebulized albuterol significantly improved the clinical score and reduced the respiratory rate of those with recurrent wheezing relative to those in the randomized groups. We conclude that nebulized albuterol is effective in the treatment of infants with recurrent wheezing, but there was no demonstrable efficacy of orally administered or nebulized albuterol in relieving the respiratory distress of infants with bronchiolitis in Egypt.

Caretaker recognition of respiratory signs in children: correlation with physical examination findings, x-ray diagnosis and pulse oximetry.

Caretaker recognition of clinical utility of respiratory signs and symptoms in the prediction of pneumonia was examined in a prospective study of infants and children in four cities in Egypt. In all 688 children aged 2 months-5 years presenting with a history and/or physical examination findings of cough and difficult or fast breathing were recruited from out-patient health facilities. The validity of caretaker terms was determined using paediatrician observation of standard respiratory signs and symptoms, x-ray diagnosis and pulse oximetry as standards. The sensitivity of 'nahagan' (Egyptian Arabic for fast breathing) for identifying elevated respiratory rate was 78% +/- 4, and was slightly higher for < 12 month olds (85% +/- 5) versus children aged 1-5 years (74% +/- 5). 'Sedro tale nazel', which describes the chest as moving up and down, was a sensitive (86% +/- 3) and specific (60% +/- 4) indicator of chest indrawing. 'Tazyeek' (wheeze) had a sensitivity of 75% +/- 3 and specificity of 66% +/- 4 when compared to paediatrician assessment of wheezing during physical examination. Although not specific, the caretaker terms, 'nahagan' or 'nafas seria' (fast breathing) and 'sedro tale nazel' (chest indrawing), either spontaneously or after asking, were sensitive (> 71%) indicators of radiologic pneumonia and oxygen desaturation, and therefore can be used to prompt timely health seeking behaviour in these settings.

Cough and cold medicine use in young children: a survey of Maryland pediatricians.

Among 307 Maryland pediatricians responding to a mail survey, recommendation or prescription of cough and cold medicines for children under 36 months of age was found to be related to the patient's age, as well as to the physician's year of graduation and type of practice.

Potential interventions for preventing pneumonia among young children: lack of effect of antibiotic treatment for upper respiratory infections.

Upper respiratory infections (URI) are a source of significant morbidity in childhood and have been associated with the development of certain bacterial infections. However, the high incidence of URI contrasted with the low incidence of lower respiratory infection (LRI) suggests a low rate of development of viral or bacterial LRI after URI. Because the etiology of URI is primarily viral, antibiotics do not have any significant effect on the URI episode itself but have been used to treat URI in hopes of preventing bacterial complications after URI. Meta-analysis of studies in developed and developing settings suggests that antibiotic treatment of children with URI does not shorten the course of URI and does not prevent the development of pneumonia. Several studies reporting both positive and negative results could not be included in the meta-analysis because they were not randomized trials or did not detail LRI outcomes in children sufficiently. Because of limitations in study design and definition of LRI, research in this area cannot be considered definitive. However, the weight of theoretical and experimental evidence is against antibiotic treatment of URI as a means of preventing the development of pneumonia after URI.

Assessment of respiratory rate and chest indrawing in children with ARI by primary care physicians in Egypt.

In a baseline study for training purposes, two indicators of acute respiratory infections (the respiratory rate (RR) and chest indrawing) were assessed by Ministry of Health physicians in Egypt using a WHO test videotape. Chest indrawing, as defined by the WHO Acute Respiratory Infections (ARI) programme, was not widely recognized by current health personnel. Viewing a WHO training videotape led to significantly more correct assessments of chest indrawing compared with a group that had not viewed this videotape. The accuracy of using a timer versus a watch, and a 30-second versus 60-second counting interval was also evaluated. Rates counted over 60 seconds were more accurate than 30-second counts although the difference between them was not clinically significant. Counting of rates using timers with audible cues was comparable to using watches with second hands. Careful training of primary health workers in the assessment of RR and chest indrawing is essential if these clinical findings are to be used as reliable indicators in pneumonia treatment algorithms.

PIP: The timely treatment of acute lower respiratory tract infections (ALRI) in children depends upon the correct assessment of clinical findings. In the context of launching a national ALRI control program in Egypt, the authors surveyed the knowledge, attitudes, and practices of physicians in measuring respiratory rates (RR); examined the effect of a World Health Organization training videotape upon the recognition of chest indrawing; and examined the effect of different time intervals and providing audible timers on the accuracy of RR assessment. 320 Ministry of Health physicians participated in the study; 45% from maternal-child health care units, 30% from urban health centers, 18% in rural health units, and 7% in the district hospital or in school health. It was found that chest indrawing was not widely recognized by current health personnel and that the training compared with groups of physicians which were not exposed to the intervention. It was also found that counting RR for 60 seconds was more accurate than 30-second counts, but the difference between the 2 approaches was not clinically significant. Rate counting with audible cue timers was comparable to using watches with second hands. It is clear that primary health workers need to be carefully trained in assessing RR and chest indrawing if these clinical findings are to be used as reliable indicators in pneumonia treatment algorithms.
