Chest radiograph in acute respiratory infections in children

The current status of community-acquired pneumonia management and prevention in children under 5 years of age in India: a review

India has the highest number of global deaths of children under 5 years of age. In the year 2015, it was reported that there were 5.9 million deaths of children under 5 years of age globally, of which 1.2 million (20%) occurred in India alone. Currently, India has an under 5 mortality rate of 48 per 1000 live births. Community-acquired pneumonia contributes to about one sixth of this mortality. Fast breathing is the key symptom of community-acquired pneumonia. The World Health Organization recently categorized community-acquired pneumonia in children under 5 years of age into two, pneumonia, and severe pneumonia. Fast breathing with or without chest in-drawing is categorized as pneumonia and fast breathing with any of danger signs as severe pneumonia. Because effective vaccines against two of the common organisms causing community-acquired pneumonia, namely Streptococcus pneumoniae and Haemophilus influenzae type b, are available, there should be urgent and phased introduction into the Indian Universal Immunization Programme. Several preventable risk factors of community-acquired pneumonia such as lack of exclusive breast feeding for first 6 months of life, inappropriate complimentary feeding, iron deficiency anemia, malnutrition, and indoor air pollution should be adequately addressed. The community should be aware about the signs and symptoms of community-acquired pneumonia and its danger signs so that delay in qualified care seeking can be avoided. To achieve the sustainable development goal of ⩽25 under five deaths per 1000 live births by 2030, a multipronged approach is the need of the hour.

Lower respiratory tract infections

Acute lower respiratory infections (ALRI) are the major cause of morbidity and mortality in young children worldwide. ALRIs are important indicators of the health disparities that persist between Indigenous and non-Indigenous children in developed countries. Bronchiolitis and pneumonia account for the majority of the ALRI burden. The epidemiology, diagnosis, and management of these diseases in Indigenous children are discussed. In comparison with non-Indigenous children in developing countries they have higher rates of disease, more complications, and their management is influenced by several unique factors including the epidemiology of disease and, in some remote regions, constraints on hospital referral and access to highly trained staff. The prevention of repeat infections and the early detection and management of chronic lung disease is critical to the long-term respiratory and overall health of these children.

WITHDRAWN: Chest radiograph in acute respiratory infections

BACKGROUND

Chest radiography is widely used during the management of acute lower respiratory infections, but the benefits are unknown.

OBJECTIVES

To assess the effects of chest radiography on clinical outcome in acute lower respiratory infections.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 1), MEDLINE (1950 to January 2007) and EMBASE (January 1976 to February 2007).

SELECTION CRITERIA

Randomised or quasi-randomised trials of chest radiography in acute respiratory infections.

DATA COLLECTION AND ANALYSIS

Both review authors independently applied the inclusion criteria, extracted data and assessed trial quality.

MAIN RESULTS

We identified two trials. One, of 522 outpatient children (and performed by the review authors), found that 46% of both radiography and control participants had recovered by seven days (relative risk (RR) 1.01, 95% confidence interval (CI) 0.79 to 1.31). Thirty-three per cent of radiography participants and 32% of control participants made a subsequent hospital visit within four weeks (RR 1.02, 95% CI 0.79 to 1.30) and 3% of both radiography and control participants were subsequently admitted to hospital within four weeks (RR 1.02, 95% CI 0.41 to 2.52). The other trial involving 1502 adults attending an emergency department found no significant difference in length of illness, the single outcome prespecified for this review (mean of 16.9 days in radiograph group versus 17.0 days in control group, P > 0.05).

AUTHORS' CONCLUSIONS

There is no evidence that chest radiography improves outcome in outpatients with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to outpatients only.

Management of community-acquired pneumonia in children

Community-acquired pneumonia (CAP) is a significant cause of childhood morbidity and mortality worldwide. Viral etiology is most common in young children and decreases with age. Streptococcus pneumoniae is the single most common bacterial cause across all age groups. Atypical organisms present similarly across all age groups and may be more common than previously recognized.A bacterial pneumonia should be considered in children presenting with fever >38.5 degrees C, tachypnea, and chest recession. Oxygen therapy is life saving and should be given when oxygen saturation is <92%. For non-severe pneumonia, oral amoxicillin is the antibacterial of choice with low failure rates reported. Severely ill children are traditionally treated with parenteral antibacterials. Penicillin non-susceptible S. pneumoniae prevalence rates are increasing and have been linked to community antibacterial prescribing. Most pneumococci remain sensitive to high-dose penicillin-based antibacterials but macrolide resistance is also a problem in some communities. However, primary combination treatment with macrolides is indicated in areas where there is a high prevalence of atypical organisms. The most common complications in CAP are parapneumonic effusions and empyema. The use of ultrasonography combined with intercostal drainage augmented with the use of fibrinolytic therapy has significantly reduced the morbidity associated with these complications. There is increasing evidence that a preventative strategy with the 7-valent pneumococcal conjugate vaccine (PCV-7) results in a significant fall in CAP in early childhood.

Management of chest pain: exploring the views and experiences of chiropractors and medical practitioners in a focus group interview

BACKGROUND

We report on a multidisciplinary focus group project related to the appropriate care of chiropractic patients who present with chest pain. The prevalence and clinical management, both diagnosis and treatment, of musculoskeletal chest pain in ambulatory medical settings, was explored as the second dimension of the focus group project reported here.

METHODS

This project collected observational data from a multidisciplinary focus group composed of both chiropractic and medical professionals. The goals of the focus group were to explore the attitudes and experiences of medical and chiropractic clinicians regarding their patients with chest pain who receive care from both medical and chiropractic providers, to identify important clinical or research questions that may inform the development of 'best practices' for coordinating or managing care of chest pain patients between medical and chiropractic providers, to identify important clinical or research questions regarding the diagnosis and treatment of chest pain of musculoskeletal origin, to explore various methods that might be used to answer those questions, and to discuss the feasibility of conducting or coordinating a multidisciplinary research effort along this line of inquiry. The convenience-sample of five focus group participants included two chiropractors, two medical cardiologists, and one dual-degreed chiropractor/medical physician. The focus group was audiotaped and transcripts were prepared of the focus group interaction. Content analysis of the focus group transcripts were performed to identify key themes and concepts, using categories of narratives.

RESULTS

Six key themes emerged from the analysis of the focus group interaction, including issues surrounding (1) Diagnosis; (2) Treatment and prognosis; (3) Chest pain as a chronic, multifactorial, or comorbid condition; (4) Inter-professional coordination of care; (5) Best practices and standardization of care; and (6) Training and education.

CONCLUSION

This study carries implications for chiropractic clinical training relative to enhancing diagnostic competencies in chest pain, as well as the need to ascertain and improve those skills, competencies, and standards for referrals and sharing of clinical information that may improve cross-disciplinary coordination of care for chest pain patients.
