Rib fractures after chest physiotherapy for bronchiolitis or pneumonia in infants

Chest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old

BACKGROUND

Acute bronchiolitis is the leading cause of medical emergencies during winter months in infants younger than 24 months old. Chest physiotherapy is sometimes used to assist infants in the clearance of secretions in order to decrease ventilatory effort. This is an update of a Cochrane Review first published in 2005 and updated in 2006, 2012, and 2016.

OBJECTIVES

To determine the efficacy of chest physiotherapy in infants younger than 24 months old with acute bronchiolitis. A secondary objective was to determine the efficacy of different techniques of chest physiotherapy (vibration and percussion, passive exhalation, or instrumental).

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, LILACS, Web of Science, PEDro (October 2011 to 20 April 2022), and two trials registers (5 April 2022).

SELECTION CRITERIA

Randomised controlled trials (RCTs) in which chest physiotherapy was compared to control (conventional medical care with no physiotherapy intervention) or other respiratory physiotherapy techniques in infants younger than 24 months old with bronchiolitis.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

Our update of the searches dated 20 April 2022 identified five new RCTs with 430 participants. We included a total of 17 RCTs (1679 participants) comparing chest physiotherapy with no intervention or comparing different types of physiotherapy. Five trials (246 participants) assessed percussion and vibration techniques plus postural drainage (conventional chest physiotherapy), and 12 trials (1433 participants) assessed different passive flow-oriented expiratory techniques, of which three trials (628 participants) assessed forced expiratory techniques, and nine trials (805 participants) assessed slow expiratory techniques. In the slow expiratory subgroup, two trials (78 participants) compared the technique with instrumental physiotherapy techniques, and two recent trials (116 participants) combined slow expiratory techniques with rhinopharyngeal retrograde technique (RRT). One trial used RRT alone as the main component of the physiotherapy intervention. Clinical severity was mild in one trial, severe in four trials, moderate in six trials, and mild to moderate in five trials. One study did not report clinical severity. Two trials were performed on non-hospitalised participants. Overall risk of bias was high in six trials, unclear in five, and low in six trials. The analyses showed no effects of conventional techniques on change in bronchiolitis severity status, respiratory parameters, hours with oxygen supplementation, or length of hospital stay (5 trials, 246 participants).  Regarding instrumental techniques (2 trials, 80 participants), one trial observed similar results in bronchiolitis severity status when comparing slow expiration to instrumental techniques (mean difference 0.10, 95% confidence interval (C) -0.17 to 0.37).  Forced passive expiratory techniques failed to show an effect on bronchiolitis severity in time to recovery (2 trials, 509 participants; high-certainty evidence) and time to clinical stability (1 trial, 99 participants; high-certainty evidence) in infants with severe bronchiolitis. Important adverse effects were reported with the use of forced expiratory techniques.  Regarding slow expiratory techniques, a mild to moderate improvement was observed in bronchiolitis severity score (standardised mean difference -0.43, 95% CI -0.73 to -0.13; I2 = 55%; 7 trials, 434 participants; low-certainty evidence). Also, in one trial an improvement in time to recovery was observed with the use of slow expiratory techniques. No benefit was observed in length of hospital stay, except for one trial which showed a one-day reduction. No effects were shown or reported for other clinical outcomes such as duration on oxygen supplementation, use of bronchodilators, or parents' impression of physiotherapy benefit.

AUTHORS' CONCLUSIONS

We found low-certainty evidence that passive slow expiratory technique may result in a mild to moderate improvement in bronchiolitis severity when compared to control. This evidence comes mostly from infants with moderately acute bronchiolitis treated in hospital. The evidence was limited with regard to infants with severe bronchiolitis and those with moderately severe bronchiolitis treated in ambulatory settings. We found high-certainty evidence that conventional techniques and forced expiratory techniques result in no difference in bronchiolitis severity or any other outcome. We found high-certainty evidence that forced expiratory techniques in infants with severe bronchiolitis do not improve their health status and can lead to severe adverse effects. Currently, the evidence regarding new physiotherapy techniques such as RRT or instrumental physiotherapy is scarce, and further trials are needed to determine their effects and potential for use in infants with moderate bronchiolitis, as well as the potential additional effect of RRT when combined with slow passive expiratory techniques. Finally, the effectiveness of combining chest physiotherapy with hypertonic saline should also be investigated.

Chest physiotherapy for pneumonia in adults

BACKGROUND

Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia. This is an update of a review first published in 2010 and updated in 2013.

OBJECTIVES

To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults.

SEARCH METHODS

We updated our searches in the following databases to May 2022: the Cochrane Central Register of Controlled Trials (CENTRAL) via OvidSP, MEDLINE via OvidSP (from 1966), Embase via embase.com (from 1974), Physiotherapy Evidence Database (PEDro) (from 1929), CINAHL via EBSCO (from 2009), and the Chinese Biomedical Literature Database (CBM) (from 1978).

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs assessing the efficacy of chest physiotherapy for treating pneumonia in adults.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included two new trials in this update (540 participants), for a total of eight RCTs (974 participants). Four RCTs were conducted in the United States, two in Sweden, one in China, and one in the United Kingdom. The studies looked at five types of chest physiotherapy: conventional chest physiotherapy; osteopathic manipulative treatment (OMT, which includes paraspinal inhibition, rib raising, and myofascial release); active cycle of breathing techniques (which includes active breathing control, thoracic expansion exercises, and forced expiration techniques); positive expiratory pressure; and high-frequency chest wall oscillation. We assessed four trials as at unclear risk of bias and four trials as at high risk of bias. Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving mortality, but the certainty of evidence is very low (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.15 to 7.13; 2 trials, 225 participants; I² = 0%). OMT (versus placebo) may have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.43, 95% CI 0.12 to 1.50; 3 trials, 327 participants; I² = 0%). Similarly, high-frequency chest wall oscillation (versus no physiotherapy) may also have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.75, 95% CI 0.17 to 3.29; 1 trial, 286 participants). Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.93, 95% CI 0.56 to 1.55; 2 trials, 225 participants; I² = 85%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.60, 95% CI 0.29 to 1.23; 1 trial, 32 participants). OMT (versus placebo) may improve cure rate, but the certainty of evidence is very low (RR 1.59, 95% CI 1.01 to 2.51; 2 trials, 79 participants; I² = 0%). OMT (versus placebo) may have little to no effect on mean duration of hospital stay, but the certainty of evidence is very low (mean difference (MD) -1.08 days, 95% CI -2.39 to 0.23; 3 trials, 333 participants; I² = 50%). Conventional chest physiotherapy (versus no physiotherapy, MD 0.7 days, 95% CI -1.39 to 2.79; 1 trial, 54 participants) and active cycle of breathing techniques (versus no physiotherapy, MD 1.4 days, 95% CI -0.69 to 3.49; 1 trial, 32 participants) may also have little to no effect on duration of hospital stay, but the certainty of evidence is very low. Positive expiratory pressure (versus no physiotherapy) may reduce the mean duration of hospital stay by 1.4 days, but the certainty of evidence is very low (MD -1.4 days, 95% CI -2.77 to -0.03; 1 trial, 98 participants). Positive expiratory pressure (versus no physiotherapy) may reduce the duration of fever by 0.7 days, but the certainty of evidence is very low (MD -0.7 days, 95% CI -1.36 to -0.04; 1 trial, 98 participants). Conventional chest physiotherapy (versus no physiotherapy, MD 0.4 days, 95% CI -1.01 to 1.81; 1 trial, 54 participants) and OMT (versus placebo, MD 0.6 days, 95% CI -1.60 to 2.80; 1 trial, 21 participants) may have little to no effect on duration of fever, but the certainty of evidence is very low. OMT (versus placebo) may have little to no effect on the mean duration of total antibiotic therapy, but the certainty of evidence is very low (MD -1.07 days, 95% CI -2.37 to 0.23; 3 trials, 333 participants; I² = 61%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on duration of total antibiotic therapy, but the certainty of evidence is very low (MD 0.2 days, 95% CI -4.39 to 4.69; 1 trial, 32 participants). High-frequency chest wall oscillation plus fibrobronchoscope alveolar lavage (versus fibrobronchoscope alveolar lavage alone) may reduce the MD of intensive care unit (ICU) stay by 3.8 days (MD -3.8 days, 95% CI -5.00 to -2.60; 1 trial, 286 participants) and the MD of mechanical ventilation by three days (MD -3 days, 95% CI -3.68 to -2.32; 1 trial, 286 participants), but the certainty of evidence is very low. One trial reported transient muscle tenderness emerging after OMT in two participants. In another trial, three serious adverse events led to early withdrawal after OMT. One trial reported no adverse events after positive expiratory pressure treatment. Limitations of this review were the small sample size and unclear or high risk of bias of the included trials.

AUTHORS' CONCLUSIONS

The inclusion of two new trials in this update did not change the main conclusions of the original review. The current evidence is very uncertain about the effect of chest physiotherapy on improving mortality and cure rate in adults with pneumonia. Some physiotherapies may slightly shorten hospital stays, fever duration, and ICU stays, as well as mechanical ventilation. However, all of these findings are based on very low certainty evidence and need to be further validated.

Rib fractures in infancy, case-series and register case-control study from Sweden

OBJECTIVES

To assess cases with rib fractures in infants under observation for or with an abuse diagnosis, and to compare risk factors with that in infants with fractures but no abuse diagnosis.

METHODS

Design was case-series and register case-control of infants (aged <1 year) with rib fractures. Data was clinical records for the case-series (n = 26) and from national health registers for the case-controls (n = 28 and n = 31). Outcome measures were maternal and perinatal characteristics, reasons for appointment, examination, diagnoses, blood tests, and radiologic findings.

RESULTS

The case-series had a median age of 70 days. A majority were detected through a skeletal survey for abuse investigation. Sixteen were boys, three were preterm and six were small-for-gestational age. Three carers had noticed popping sound from the chest; no infants showed signs of pain at physical examination. Mean number of fractures was 4.2, and 24 had callus. Bone mineralisation was scarcely reported. Metabolic panel was not uniformly analysed. The register case-control had a median age of 76 days, sharing risk factors such as maternal overweight/obesity, male sex, prematurity, and being small-for-gestational age. Cases more often had subdural haemorrhage, retinal haemorrhage, or long-bone fractures, controls more often had neonatal morbidity, respiratory infection, or a fall accident. Detection of fracture at time of a major surgery (n = 6) and rickets/vitamin D deficiency (n = 5) appeared in both groups, but was delayed among the cases.

CONCLUSIONS

Rib fractures in young infants, diagnosed as abuse, are usually asymptomatic and healing. A substantial proportion had metabolic risk factors, suggesting false positive cases.

Fisioterapia respiratória não altera agudamente os parâmetros fisiológicos ou os níveis de dor em prematuros com síndrome do desconforto respiratório internados em unidade de terapia intensiva

RESUMO Objetivo: avaliar a ocorrência de alterações fisiológicas adversas agudas e a presença de dor em recém-nascidos prematuros com síndrome do desconforto respiratório internados em uma unidade de terapia intensiva neonatal após a fisioterapia respiratória. Métodos: estudo transversal que avaliou 30 neonatos prematuros em três momentos, sendo eles Momento um (M1), antes da fisioterapia, Momento dois (M2), imediatamente após a fisioterapia, e Momento três (M3), 15 minutos após. Consideraram-se alterações fisiológicas as variações da frequência cardíaca (FC), da frequência respiratória (FR), da saturação periférica de oxigênio (SpO2) e da temperatura corporal. A presença de dor foi avaliada pelas escalas neonatal infant pain scale e neonatal facial coding system. Resultados: houve aumento estatisticamente significativo na FC no M2 quando comparados os três momentos, porém com retorno aos valores basais 15 minutos após a fisioterapia. Outras variáveis fisiológicas (FR, SpO2 e temperatura) e a avaliação da dor não apresentaram alterações significativas. Conclusão: parâmetros fisiológicos e comportamentais permaneceram estáveis após a realização da fisioterapia respiratória, com discretas alterações imediatamente após o procedimento, mas com retorno aos valores basais, indicando que a fisioterapia respiratória não alterou agudamente os sinais vitais e os níveis de dor dos neonatos.

Findings of metabolic bone disease in infants with unexplained fractures in contested child abuse investigations: a case series of 75 infants

Background Infants who present with multiple unexplained fractures (MUF) are often diagnosed as victims of child abuse when parents deny wrongdoing and cannot provide a plausible alternative explanation. Herein we describe evidence of specific and commonly overlooked radiographic abnormalities and risk factors that suggest a medical explanation in such cases. Methods We evaluated such infants in which we reviewed the radiographs for signs of poor bone mineralization. We reviewed medical, pregnancy and family histories. Results Seventy-five of 78 cases showed poor bone mineralization with findings of healing rickets indicating susceptibility to fragility fractures that could result from a wide variety of causes other than child abuse. We found risk factors that could explain the poor bone mineralization: maternal and infant vitamin D deficiency (VDD), decreased fetal bone loading, prematurity and others. Most infants had more than one risk factor indicating that this bone disorder is a multifactorial disorder that we term metabolic bone disease of infancy (MBDI). Maternal and infant VDD were common. When tested, 1,25-dihydroxyvitamin D levels were often elevated, indicating metabolic bone disease. Conclusions Child abuse is sometimes incorrectly diagnosed in infants with MUF. Appreciation of the radiographic signs of MBDI (healing rickets), risk factors for MBDI and appropriate laboratory testing will improve diagnostic accuracy in these cases.

Airway clearance therapy in acute paediatric respiratory illness: A state-of-the-art review

Background

Despite unclear evidence of effectiveness or safety, airway clearance therapy (ACT) is frequently performed in infants and children with acute pulmonary disease.

Objectives

The aim of this review was to critically synthesise published evidence, expert opinion and pathophysiological principles to describe the indications, effects, precautions and application of commonly used ACT modalities for managing infants and children with acute pulmonary disease.

Method

A comprehensive narrative review of published literature was conducted. Articles describing paediatric populations were prioritised, but adult and animal studies were also considered where appropriate.

Results

There is a dearth of high-level evidence supporting the use of ACT in acutely ill infants and children. Conversely, studies have highlighted the lack of effect of different modalities for a variety of conditions, and in some cases serious associated complications have been reported.Airway clearance therapy may be considered when there is retention of pulmonary secretions, and the consequential airway obstruction impacts either acutely on respiratory mechanics and gaseous exchange and/or has the potential for long-term adverse sequelae [a condition that is the consequence of a previous disease or injury]. However, it should not be considered a routine intervention.

Conclusion

Airway clearance therapy should not be performed routinely in children admitted to hospital with acute respiratory conditions. Patients should be clinically assessed and treatment planned according to individual presentation, in those with signs and symptoms that are potentially amenable to ACT.

Clinical implications

This review can serve as a guide for physiotherapists in the respiratory management of children with acute respiratory illness, as well as identifying areas for clinical research.

[Respiratory physiotherapy in acute viral bronchiolitis in the newborn. Pro/con arguments]

This article reports an exchange of unbiased arguments between Mr Guy Postiaux speaking in favour of respiratory physiotherapy in acute viral bronchiolitis in the newborn and Prof. Jean-Christoph Dubus arguing against. A review of the literature suggests that traditional methods of physiotherapy should be abandoned because they are not validated and because they have harmful side effects. The latest Cochrane revue (2016) suggests the use of slow expiration techniques that have some validated elements and cause no harmful side effects. Large multicentre studies should be undertaken to confirm or refute the results of the five studies in the Cochrane review. Their analysis would allow extraction of objective evidence for the efficacy of slow expiration techniques on the relief of bronchopulmonary obstruction and the reduction of the degree of severity in the short and medium term. Studies of the effect of ambulatory respiratory physiotherapy for bronchiolitis of a moderate degree not requiring hospitalisation are not available. An evaluation is needed which is based on the pathophysiology of multifactorial bronchial obstruction and on the physical signs, of which auscultation is the cornerstone.

Keeping an Open Mind: Cognitive Bias in the Evaluation of an Infant with Posterior-Lateral Rib Fractures

A four-month-old former premature male is incidentally found to have posterior-lateral rib fractures during evaluation of a febrile illness. This finding led to the initiation of a workup for nonaccidental trauma. A thorough history and physical exam ultimately led to the diagnosis, which was not related to abuse. This case highlights a rare sequela of patent ductus arteriosus repair, cautions medical teams to remain aware of how cognitive bias can affect diagnostic decision-making, and emphasizes the importance of a thorough history, physical exam, and medical record review in cases of suspected nonaccidental trauma.

Autogenic Drainage in Children With Cystic Fibrosis

PURPOSE

Airway clearance is an essential part of the management of cystic fibrosis (CF) as it facilitates clearance of viscous pulmonary secretions. This review aimed to determine the effect of autogenic drainage (AD) and assisted autogenic drainage (AAD) compared with no, sham, or other types of airway clearance in children with CF.

SUMMARY OF KEY POINTS

Two pediatric randomized cross-over trials were identified on the use of AD in children with CF; no studies were available on the use of AAD. In one study AD had a positive influence on the Huang score, and is preferred over postural drainage in this population.

CONCLUSIONS AND RECOMMENDATIONS

We could not determine the efficacy of AD and AAD in children with CF. We recommend the implementation of pediatric-specific randomized controlled trials with adequate sample sizes, appropriate clinical outcome measures, and analysis of adverse effects.

Chest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old

BACKGROUND

This Cochrane review was first published in 2005 and updated in 2007, 2012 and now 2015. Acute bronchiolitis is the leading cause of medical emergencies during winter in children younger than two years of age. Chest physiotherapy is sometimes used to assist infants in the clearance of secretions in order to decrease ventilatory effort.

OBJECTIVES

To determine the efficacy of chest physiotherapy in infants aged less than 24 months old with acute bronchiolitis. A secondary objective was to determine the efficacy of different techniques of chest physiotherapy (for example, vibration and percussion and passive forced exhalation).

SEARCH METHODS

We searched CENTRAL (2015, Issue 9) (accessed 8 July 2015), MEDLINE (1966 to July 2015), MEDLINE in-process and other non-indexed citations (July 2015), EMBASE (1990 to July 2015), CINAHL (1982 to July 2015), LILACS (1985 to July 2015), Web of Science (1985 to July 2015) and Pedro (1929 to July 2015).

SELECTION CRITERIA

Randomised controlled trials (RCTs) in which chest physiotherapy was compared against no intervention or against another type of physiotherapy in bronchiolitis patients younger than 24 months of age.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data. Primary outcomes were change in the severity status of bronchiolitis and time to recovery. Secondary outcomes were respiratory parameters, duration of oxygen supplementation, length of hospital stay, use of bronchodilators and steroids, adverse events and parents' impression of physiotherapy benefit. No pooling of data was possible.

MAIN RESULTS

We included 12 RCTs (1249 participants), three more than the previous Cochrane review, comparing physiotherapy with no intervention. Five trials (246 participants) evaluated conventional techniques (vibration and percussion plus postural drainage), and seven trials (1003 participants) evaluated passive flow-oriented expiratory techniques: slow passive expiratory techniques in four trials, and forced passive expiratory techniques in three trials.Conventional techniques failed to show a benefit in the primary outcome of change in severity status of bronchiolitis measured by means of clinical scores (five trials, 241 participants analysed). Safety of conventional techniques has been studied only anecdotally, with one case of atelectasis, the collapse or closure of the lung resulting in reduced or absent gas exchange, reported in the control arm of one trial.Slow passive expiratory techniques failed to show a benefit in the primary outcomes of severity status of bronchiolitis and in time to recovery (low quality of evidence). Three trials analysing 286 participants measured severity of bronchiolitis through clinical scores, with no significant differences between groups in any of these trials, conducted in patients with moderate and severe disease. Only one trial observed a transient significant small improvement in the Wang clinical score immediately after the intervention in patients with moderate severity of disease. There is very low quality evidence that slow passive expiratory techniques seem to be safe, as two studies (256 participants) reported that no adverse effects were observed.Forced passive expiratory techniques failed to show an effect on severity of bronchiolitis in terms of time to recovery (two trials, 509 participants) and time to clinical stability (one trial, 99 participants analysed). This evidence is of high quality and corresponds to patients with severe bronchiolitis. Furthermore, there is also high quality evidence that these techniques are related to an increased risk of transient respiratory destabilisation (risk ratio (RR) 10.2, 95% confidence interval (CI) 1.3 to 78.8, one trial) and vomiting during the procedure (RR 5.4, 95% CI 1.6 to 18.4, one trial). Results are inconclusive for bradycardia with desaturation (RR 1.0, 95% CI 0.2 to 5.0, one trial) and bradycardia without desaturation (RR 3.6, 95% CI 0.7 to 16.9, one trial), due to the limited precision of estimators. However, in mild to moderate bronchiolitis patients, forced expiration combined with conventional techniques produced an immediate relief of disease severity (one trial, 13 participants).

AUTHORS' CONCLUSIONS

None of the chest physiotherapy techniques analysed in this review (conventional, slow passive expiratory techniques or forced expiratory techniques) have demonstrated a reduction in the severity of disease. For these reasons, these techniques cannot be used as standard clinical practice for hospitalised patients with severe bronchiolitis. There is high quality evidence that forced expiratory techniques in severe patients do not improve their health status and can lead to severe adverse events. Slow passive expiratory techniques provide an immediate and transient relief in moderate patients without impact on duration. Future studies should test the potential effect of slow passive expiratory techniques in mild to moderate non-hospitalised patients and patients who are respiratory syncytial virus (RSV) positive. Also, they could explore the combination of chest physiotherapy with salbutamol or hypertonic saline.

Chest physiotherapy in children with acute bacterial pneumonia

BACKGROUND

Pneumonia is the single leading cause of death in children younger than 5 years of age. Chest physiotherapy is often prescribed as an additional therapy in children with pneumonia. Different chest physiotherapy techniques are available that aim to improve airway clearance, gas exchange and reduce the work of breathing. However, it is unclear if these techniques are effective in this population.

OBJECTIVE

The present review aimed to determine the efficacy of different chest physiotherapy techniques compared with no physiotherapy or other chest physiotherapy treatments in hospitalised children with bacterial pneumonia.

METHOD

Six electronic databases (PubMed, Medline, Cochrane Library, PEDro, CINAHL and Africa-wide information), clinicaltrials.gov and pactr.org were searched for eligible studies.

RESULTS

Two randomised controlled trials and one ongoing study were identified. Neither completed trial reported differences between the control and intervention groups, although one study reported a longer duration of coughing (p = 0.04) and rhonchi (p = 0.03) in the intervention group.

CONCLUSION

Because of the limited number of included articles and different presentations of outcome measures, we could not reject or accept chest physiotherapy as either an effective or harmful treatment option in this population.

Chest Physiotherapy in the Pediatric Intensive Care Unit

Despite widespread practice, there is very little, high-level evidence supporting the indications for and effectiveness of cardiopulmonary/chest physiotherapy (CPT) in critically ill infants and children. Conversely, most studies highlight the detrimental effects or lack of effect of different manual modalities. Conventional CPT should not be a routine intervention in the pediatric intensive care unit, but can be considered when obstructive secretions are present which impact on lung mechanics and/or gaseous exchange and/or where there is the potential for long-term complications. Techniques such as positioning, early mobilization, and rehabilitation have been shown to be beneficial in adult intensive care patients; however, little attention has been paid to this important area of practice in pediatric intensive care units. This article presents a narrative review of chest physiotherapy in pediatric critical illness, including effects, indications, precautions, and specific treatment modalities and techniques.

[Acute bronchiolitis and chest physiotherapy: the end of a reign]

Every winter, numerous infants are hospitalized for acute bronchiolitis. The severity criteria and symptomatic treatment are well known, with chest physiotherapy codified in 2000 by the French Health Authority (HAS) consensus conference (with techniques varying from one country to another) and becoming nearly systematic for the treatment of bronchial obstruction in infants. However, is this treatment really effective and legitimate for acute bronchiolitis? The objective of this study was to review the main studies on this subject. Few studies are available and most have a low level of evidence. However, they all tend to agree that chest physiotherapy does not change the natural history of the disease and most particularly the duration of hospitalization. Therefore, it does not seem that the prescription of chest physiotherapy in infant acute bronchiolitis is recommended.

Chest physiotherapy is not clinically indicated for infants receiving outpatient care for acute wheezing episodes

AIM

To evaluate the effectiveness of chest physiotherapy (CPT), which provides slow and long expiratory flow and assisted cough techniques, in infants receiving outpatient care for acute wheezing episodes.

METHODS

Forty-eight infants with moderate acute wheezing episodes were randomised to receive either salbutamol MDI with CPT (n = 25) or without CPT (n = 23). The clinical score and SpO2 levels were recorded, before and after treatment, in a blinded design. The primary outcome was discharge after the first hour of treatment: clinical score ≤5/12 and SpO2 ≥ 93%. Secondary outcomes were the number of admissions to hospital after the second hour, use of oral corticosteroid bursts and admissions to hospital on day seven.

RESULTS

There were no differences between children with and without CPT in discharge rate (92% vs. 87%), clinical score (median [IQR]: 2.8 [2.2-3.3] vs. 3.4 [2.8-4.1]) and SpO2 = (96.4 [95.7-97.1] vs. 96.0 [94.9-96.5]) after the first hour of treatment or in the number of hospital admissions after the second hour. No differences were observed at days seven and 28 following treatment.

CONCLUSION

There was no evidence of clinical benefits from these specific CPT techniques for infants receiving outpatient care for acute wheezing episodes.

Chest physiotherapy for pneumonia in adults

BACKGROUND

Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia.

OBJECTIVES

To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults.

SEARCH METHODS

We searched CENTRAL 2012, Issue 11, MEDLINE (1966 to November week 2, 2012), EMBASE (1974 to November 2012), Physiotherapy Evidence Database (PEDro) (1929 to November 2012), CINAHL (2009 to November 2012) and CBM (1978 to November 2012).

SELECTION CRITERIA

Randomised controlled trials (RCTs) assessing the efficacy of chest physiotherapy for treating pneumonia in adults.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility, extracted data and appraised trial quality. Primary outcomes were mortality and cure rate. We used risk ratios (RR) and mean difference (MD) for individual trial results in the data analysis. We performed meta-analysis and measured all outcomes with 95% confidence intervals (CI).

MAIN RESULTS

Six RCTs (434 participants) appraised four types of chest physiotherapy (conventional chest physiotherapy; osteopathic manipulative treatment (which includes paraspinal inhibition, rib raising and myofascial release); active cycle of breathing techniques (which include active breathing control, thoracic expansion exercises and forced expiration techniques); and positive expiratory pressure).None of the physiotherapies (versus no physiotherapy or placebo) improved mortality rates of adults with pneumonia.Conventional chest physiotherapy (versus no physiotherapy), active cycle of breathing techniques (versus no physiotherapy) and osteopathic manipulative treatment (versus placebo) did not increase the cure rate or chest X-ray improvement rate.Osteopathic manipulative treatment (versus placebo) and positive expiratory pressure (versus no physiotherapy) reduced the mean duration of hospital stay by 2.0 days (mean difference (MD) -2.0 days, 95% CI -3.5 to -0.6) and 1.4 days (MD -1.4 days, 95% CI -2.8 to -0.0), respectively. Conventional chest physiotherapy and active cycle of breathing techniques did not.Positive expiratory pressure (versus no physiotherapy) reduced fever duration (MD -0.7 day, 95% CI -1.4 to -0.0). Osteopathic manipulative treatment did not.Osteopathic manipulative treatment (versus placebo) reduced the duration of intravenous (MD -2.1 days, 95% CI -3.4 to -0.9) and total antibiotic treatment (MD -1.9 days, 95% CI -3.1 to -0.7).Limitations of this review are that the studies addressing osteopathic manipulative treatment were small, and that six published studies which appear to meet the inclusion criteria are awaiting classification.

AUTHORS' CONCLUSIONS

Based on current limited evidence, chest physiotherapy might not be recommended as routine additional treatment for pneumonia in adults.

Chest physiotherapy using passive expiratory techniques does not reduce bronchiolitis severity: a randomised controlled trial

Chest physiotherapy (CP) using passive expiratory manoeuvres is widely used in Western Europe for the treatment of bronchiolitis, despite lacking evidence for its efficacy. We undertook an open randomised trial to evaluate the effectiveness of CP in infants hospitalised for bronchiolitis by comparing the time to clinical stability, the daily improvement of a severity score and the occurrence of complications between patients with and without CP. Children <1 year admitted for bronchiolitis in a tertiary hospital during two consecutive respiratory syncytial virus seasons were randomised to group 1 with CP (prolonged slow expiratory technique, slow accelerated expiratory flow, rarely induced cough) or group 2 without CP. All children received standard care (rhinopharyngeal suctioning, minimal handling, oxygen for saturation ≥92%, fractionated meals). Ninety-nine eligible children (mean age, 3.9 months), 50 in group 1 and 49 in group 2, with similar baseline variables and clinical severity at admission. Time to clinical stability, assessed as primary outcome, was similar for both groups (2.9 ± 2.1 vs. 3.2 ± 2.8 days, P = 0.45). The rate of improvement of a clinical and respiratory score, defined as secondary outcome, only showed a slightly faster improvement of the respiratory score in the intervention group when including stethoacoustic properties (P = 0.044). Complications were rare but occurred more frequently, although not significantly (P = 0.21), in the control arm. In conclusion, this study shows the absence of effectiveness of CP using passive expiratory techniques in infants hospitalised for bronchiolitis. It seems justified to recommend against the routine use of CP in these patients.

Chest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old

BACKGROUND

This is an update of the original Cochrane review published in 2005 and updated in 2007. Acute bronchiolitis is the leading cause of medical emergencies during winter in children younger than two years of age. Chest physiotherapy is thought to assist infants in the clearance of secretions and to decrease ventilatory effort.

OBJECTIVES

The main objective was to determine the efficacy of chest physiotherapy in infants aged less than 24 months old with acute bronchiolitis. A secondary objective was to determine the efficacy of different techniques of chest physiotherapy (for example, vibration and percussion and passive forced exhalation).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4) which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (1966 to November week 3, 2011), MEDLINE in-process and other non-indexed citations (8 December 2011), EMBASE.com (1990 to December 2011), CINAHL (1982 to December 2011), LILACS (1985 to December 2011) and Web of Science (1985 to December 2011).

SELECTION CRITERIA

Randomised controlled trials (RCTs) in which chest physiotherapy was compared against no intervention or against another type of physiotherapy in bronchiolitis patients younger than 24 months of age.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data. Primary outcomes were respiratory parameters and improvement in severity of disease. Secondary outcomes were length of hospital stay, duration of oxygen supplementation and the use of bronchodilators and steroids. No pooling of data was possible.

MAIN RESULTS

Nine clinical trials including 891 participants were included comparing physiotherapy with no intervention. Five trials (246 participants) evaluated vibration and percussion techniques and four trials (645 participants) evaluated passive expiratory techniques. We observed no significant differences in the severity of disease (eight trials, 867 participants). Results were negative for both types of physiotherapy. We observed no differences between groups in respiratory parameters (two trials, 118 participants), oxygen requirements (one trial, 50 participants), length of stay (five trials, 222 participants) or severe side effects (two trials, 595 participants). Differences in mild transient adverse effects (vomiting and respiratory instability) have been observed (one trial, 496 participants).

AUTHORS' CONCLUSIONS

Since the last publication of this review new good-quality evidence has appeared, strengthening the conclusions of the review. Chest physiotherapy does not improve the severity of the disease, respiratory parameters, or reduce length of hospital stay or oxygen requirements in hospitalised infants with acute bronchiolitis not on mechanical ventilation. Chest physiotherapy modalities (vibration and percussion or forced expiratory techniques) have shown equally negative results.

Análise dos sintomas, sinais clínicos e suporte de oxigênio em pacientes com bronquiolite antes e após fisioterapia respiratória durante a internação hospitalar

OBJETIVO: Avaliar os efeitos da fisioterapia em pacientes pediátricos, internados com bronquiolite. MÉTODOS: O estudo incluiu 29 pacientes menores de um ano, com diagnóstico médico de bronquiolite aguda, sem cardiopatia congênita não corrigida, neuropatia, doença pulmonar de base ou que necessitassem de suporte ventilatório, no período de março a julho de 2009. Foi avaliada, por meio de questionário, a opinião dos pais ou responsáveis acerca das condições clínicas do paciente antes e após a primeira sessão de fisioterapia. Foram realizadas manobras de desobstrução brônquica, como drenagem postural, tapotagem, vibração, aceleração de fluxo expiratório e aspiração nasotraqueal. A avaliação foi realizada diariamente por meio de exame físico antes do atendimento fisioterapêutico e 15 a 45 minutos após, seguindo uma ficha específica. Os desfechos analisados foram: modificações do suporte de oxigênio, sinais clínicos (ausculta pulmonar, presença de tiragens, oxigenação e classificação da gravidade pelo escore de Downes) e sintomas (inapetência, hipoatividade, dificuldade para dormir, obstrução nasal e tosse constante). RESULTADOS: Dos 29 pacientes avaliados, houve melhora significativa nos seguintes sinais e sintomas: ausculta pulmonar com ruídos adventícios (p<0,001), estertores subcrepitantes (p=0,017) e sibilos (p=0,010), tiragens de modo geral (p<0,001), tiragem intercostal (p<0,001) e classificação da gravidade pelo escore de Downes (p<0,001). Também foi observada melhora significativa em todos os aspectos avaliados no questionário (p<0,001). CONCLUSÕES: A fisioterapia respiratória promoveu uma melhora significante em curto prazo das condições clínicas dos pacientes com bronquiolite aguda.

Bronchiolite del lattante

La bronchiolite è un’infezione virale stagionale delle vie respiratorie basse del lattante. Il suo agente causale principale è il virus respiratorio sinciziale. La comparsa di un distress respiratorio è legata all’intensità della risposta infiammatoria delle vie aeree. Benché si tratti di una malattia frequente, le cause della suscettibilità dei lattanti a questa infezione non sono conosciute. La diagnosi è clinica. Il trattamento è sintomatico in assenza di misure specifiche. I rapporti a medio e a lungo termine di un primo episodio di bronchiolite con le recidive e con l’asma non sono spiegati. Essi potrebbero dipendere dalla natura del virus in causa al momento del primo episodio e da fattori genetici individuali.

Do resuscitation-related injuries kill infants and children?

Occasionally, individuals accused of inflicting fatal injuries on infants and young children will claim some variant of the "CPR defense," that is, they attribute the cause of injuries found at autopsy to their "untrained" resuscitative efforts. A 10-year (1994-2003) historical fixed cohort study of all pediatric forensic autopsies at the Miami-Dade County Medical Examiner Department was undertaken. To be eligible for inclusion in the study, children had to have died of atraumatic causes, with or without resuscitative efforts (N(atraumatic) = 546). Of these, 382 had a history of cardiopulmonary resuscitation (CPR; average age of 4.17 years); 248 had CPR provided by trained individuals only; 133 had CPR provided by both trained and untrained individuals; 1 had CPR provided by untrained individuals only. There was no overlap between these 3 distinct groups. Twenty-two findings potentially attributable to CPR were identified in 19:15 cases of orofacial injuries compatible with attempted endotracheal intubation; 4 cases with focal pulmonary parenchymal hemorrhage; 1 case with prominent anterior mediastinal emphysema; and 2 cases with anterior chest abrasions. There were no significant hollow or solid thoracoabdominal organ injuries. There were no rib fractures. The estimated relative risk of injury subsequent to resuscitation was not statistically different between the subset of decedents whose resuscitative attempts were made by trained individuals only, and the subset who received CPR from both trained and untrained individuals. In the single case of CPR application by an untrained individual only, no injuries resulted. The remaining 164 children dying from nontraumatic causes and who did not undergo resuscitative efforts served as a control group; no injuries were identified. This study indicates that in the pediatric population, injuries secondary to resuscitative efforts are infrequent or rare, pathophysiologically inconsequential, and predominantly orofacial in location. In our population, CPR did not result in any rib fractures or significant visceral injuries. Participation of nonmedical or untrained individuals in resuscitation did not increase the likelihood of injury.

Chest physiotherapy for pneumonia in adults

BACKGROUND

Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia.

OBJECTIVES

To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, issue 3); MEDLINE (1966 to August 2009); EMBASE (1974 to August 2009); CBM (1978 to August 2009); the National Research Register (August 2009) and Physiotherapy Evidence Database (PEDro) (1929 to August 2009).

SELECTION CRITERIA

Randomised controlled trials (RCTs) assessing the efficacy of chest physiotherapy for treating pneumonia in adults.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility, extracted data and appraised trial quality. Primary outcomes were mortality and cure rate. We used risk ratios (RR) and mean difference (MD) for individual trial results in the data analysis. We performed meta-analysis and measured all outcomes with 95% confidence intervals (CI).

MAIN RESULTS

Six RCTs (434 participants) appraised four types of chest physiotherapy (conventional chest physiotherapy; osteopathic manipulative treatment (which includes paraspinal inhibition, rib raising and myofascial release); active cycle of breathing techniques (which include active breathing control, thoracic expansion exercises and forced expiration techniques); and positive expiratory pressure).None of the physiotherapies (versus no physiotherapy or placebo) improved mortality rates of adults with pneumonia.Conventional chest physiotherapy (versus no physiotherapy), active cycle of breathing techniques (versus no physiotherapy) and osteopathic manipulative treatment (versus placebo) did not increase the cure rate or chest X-ray improvement rate.Osteopathic manipulative treatment (versus placebo) and positive expiratory pressure (versus no physiotherapy) reduced mean duration of hospital stay by 2.0 days (mean difference (MD) -2.0 days, 95% CI -3.5 to -0.6) and 1.4 days (MD -1.4 days, 95% CI -2.8 to -0.0), respectively. Conventional chest physiotherapy and active cycle of breathing techniques did not.Positive expiratory pressure (versus no physiotherapy) reduced fever duration (MD -0.7 day, 95% CI -1.4 to -0.0). Osteopathic manipulative treatment did not.Osteopathic manipulative treatment (versus placebo) reduced duration of intravenous (MD -2.1 days, 95% CI -3.4 to -0.9) and total antibiotic treatment (MD -1.9 days, 95% CI -3.1 to -0.7).Limitations of this review are that the studies addressing osteopathic manipulative treatment were small, and that the six published studies which appear to meet the inclusion criteria are awaiting classification.

AUTHORS' CONCLUSIONS

Based on current limited evidence, chest physiotherapy might not be recommended as routine adjunctive treatment for pneumonia in adults.

Rib fractures identified at post-mortem examination in sudden unexpected deaths in infancy (SUDI)

Rib fractures may be associated with non-accidental injury (NAI) in infancy, but the possible significance of fresh rib fractures in relation to resuscitation remains undetermined. Consequently, it is important to detect and confirm the presence of rib fractures when performing a post-mortem examination, particularly in the context of sudden unexpected death in infancy (SUDI). At our centre, it has been local policy to perform routine radiological skeletal surveys and detailed post-mortem examination of the ribs in all SUDI autopsies. The aim of this study is to establish the characteristics of all rib fractures identified at autopsy in the setting of SUDI from a large series of cases examined at a single specialist centre. As part of a larger review of paediatric post-mortem examinations performed at a single specialist institution over a 10-year period (1996-2005), all cases presenting as SUDI (aged 7-365 days) were identified and their anonymised records searched to identify all cases in which rib fractures were recorded. Over the 10-year period, 546 post-mortem examinations were performed for the indication of SUDI, including 94 forensic autopsies. Rib fractures were identified in 24 cases (4%). 15 infants (3% of SUDI) demonstrated healing rib fractures, of which 10 infants (67%) showed additional features suggestive of NAI. The other 9 infants (2% of SUDI) demonstrated fresh rib fractures only with no surrounding tissue reaction histologically; in 7 (78%) of these there were no other injuries and the fresh fractures were interpreted to have been caused by resuscitation-related trauma. All of the resuscitation-related fractures were situated in the anterolateral chest, in contrast to NAI-associated fractures, which were located in the anterolateral and/or posterior chest. Anterior costochondral junction fractures were also seen in a minority of NAI-associated cases, but such fractures were not seen in apparent resuscitation-related cases. Compared to healing rib fractures, which were detected on skeletal survey in 93%, fresh rib fractures were only detected in 22% of skeletal surveys. Rib fractures are uncommon in infancy and may indicate NAI, particularly when healed or healing, posterior or involving the costochondral junction. Fresh rib fractures may be missed on skeletal survey, but can be reliably detected at post-mortem examination following stripping of the pleura and detailed examination of each rib. Fresh anterolateral fractures, which may be multiple, contiguous and even bilateral, are highly likely to be related to resuscitation if there are no other associated injuries.

Birth-related mid-posterior rib fractures in neonates: a report of three cases (and a possible fourth case) and a review of the literature

BACKGROUND

Posterior rib fractures in young children have a high positive predictive value for non-accidental injury (NAI). Combined data of five studies on birth trauma (115,756 live births) showed no cases of rib fractures resulting from birth trauma. There have, however, been sporadic cases reported in the literature.

OBJECTIVE

We present three neonates with both posterior rib fractures and ipsilateral clavicular fractures resulting from birth trauma. A review of the literature is also presented. The common denominator and a possible mechanical aetiology are discussed.

MATERIALS AND METHODS

In total, 13 cases of definitive birth-related posterior rib fractures were identified.

RESULTS

Nearly all (9/10) posterior rib fractures were (as far as reported in the original publications) in the midline. In 12 of the 13 children, birth weight was high and in 7 children birth was complicated by shoulder dystocia. An interesting finding was that in cases where a clavicular fracture was present, this was on the ipsilateral side.

CONCLUSION

Radiologists, when presented with a neonate with posterior rib fractures, should be aware of this rare differential diagnosis.

Late onset of spontaneous pneumothorax complicating acute bronchiolitis in a 5-month-old infant: case report and literature review

The literature contains only a few reported cases of spontaneous pneumothorax complicating acute bronchiolitis in infants. We present a case of a 5-month-old infant with a presentation of spontaneous pneumothorax 7 days after hospitalization for acute bronchiolitis. The characteristics of this particular manifestation are discussed.

Physical abuse and neglect of children

Child maltreatment includes physical abuse and neglect, and happens in all countries and cultures. Child maltreatment usually results from interactions between several risk factors (such as parental depression, stress, and social isolation). Physicians can incorporate methods to screen for risk factors into their usual appointments with the family. Detection of physical abuse is dependent on the doctor's ability to recognise suspicious injuries, such as bruising, bite marks, burns, bone fractures, or trauma to the head or abdomen. Neglect is the most common form of child maltreatment in the USA. It can be caused by insufficient parental knowledge; intentional negligence is rare. Suspected cases of child abuse should be well documented and reported to the appropriate public agency which should assess the situation and help to protect the child.

Chest physical therapy, breathing techniques and exercise in children with CF

Chest physiotherapy in the form of airway clearance techniques and exercise has played an important role in the treatment of cystic fibrosis. Until the 1990s the primary airway clearance technique used was postural drainage combined with percussion and vibration (PD&P). It was introduced into the treatment of CF with little evidence to support its efficacy and once established, it has been difficult ethically to perform a study comparing PD&P to no treatment. A common question, yet unanswered is when should it be commenced, especially for the newly diagnosed asymptomatic CF patient? Recently, the technique of PD&P has been modified to include only non-dependant head-down positioning due to the detrimental effects of placing a person in a Trendelenburg position. In the 1990s other airway clearance techniques gained popularity, in that they could be performed independently, in a sitting position and avoided many of the detrimental effects of PD&P. These techniques include the Active cycle of breathing technique, formally called the Forced expiration technique and Autogenic drainage. Both these breathing techniques aim at using expiratory airflow to mobilize secretions up the airways and incorporate breathing strategies to assist in the homogeneity of ventilation. Studies suggest that both these techniques are as effective if not more effective than as PD&P and offer many advantages over PD&P. It has been suggested that exercise can be used as an airway clearance technique; however the literature does not support this. Rather, when exercise is used in addition to an airway clearance technique there is enhanced secretion removal and an overall benefit to the patient. Further research needs to be directed at assessing the effects of an airway clearance technique on the individual patient using appropriate outcome measures.

Imaging of the central nervous system in suspected or alleged nonaccidental injury, including the mimics

Because of the widely acknowledged controversy in nonaccidental injury, the radiologist involved in such cases must be thoroughly familiar with the imaging, clinical, surgical, pathological, biomechanical, and forensic literature from all perspectives and with the principles of evidence-based medicine. Children with suspected nonaccidental injury versus accidental injury must not only receive protective evaluation but also require a timely and complete clinical and imaging workup to evaluate pattern of injury and timing issues and to consider the mimics of abuse. All imaging findings must be correlated with clinical findings (including current and past medical record) and with laboratory and pathological findings (eg, surgical, autopsy). The medical and imaging evidence, particularly when there is only central nervous system injury, cannot reliably diagnose intentional injury. Only the child protection investigation may provide the basis for inflicted injury in the context of supportive medical, imaging, biomechanical, or pathological findings.

Chest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old

BACKGROUND

Acute bronchiolitis is the leading cause of medical emergencies during winter in children younger than two years of age. Chest physiotherapy is thought to assist infants in the clearance of secretions and to decrease ventilatory effort.

OBJECTIVES

To determine the efficacy and safety of chest physiotherapy in infants aged less than 24 months old with acute bronchiolitis.

SEARCH STRATEGY

In June 2006 we updated the searches of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2006); MEDLINE (2004 to May Week 4 2006); EMBASE (July 2004 to December 2005) and CINAHL (1982 to May Week 4 2006).

SELECTION CRITERIA

Randomised controlled trials (RCTs) in which chest physiotherapy was compared against no intervention or against another type of physiotherapy in paediatric patients younger than 24 months old.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted the data. The primary outcome was a severity clinical score. Secondary outcomes were length of hospital stay, duration of oxygen supplementation, and the use of bronchodilators and steroids.

MAIN RESULTS

Three clinical trials met the inclusion criteria. All evaluated vibration and percussion techniques with children in postural drainage positions compared to no intervention. The study populations were hospitalised infants with a clinical diagnosis of acute bronchiolitis, although one study included only infants who required nasogastric tube feeding or intravenous fluids. None of the other included trails observed any differences in the severity of the clinical score at day five, during each of the five days of the trial, or until discharge; length of hospital stay; or oxygen requirements between paediatric patients receiving chest physiotherapy and control.

AUTHORS' CONCLUSIONS

Based on the results of three RCTs, chest physiotherapy using vibration and percussion techniques does not reduce length of hospital stay, oxygen requirements, or improve the severity clinical score in infants with acute bronchiolitis. These were infants who were not on mechanical ventilation and who did not have any other co-morbidity. Chest physiotherapy using forced expiratory techniques needs to be further evaluated by clinical research.

Measurement system for gesture characterization during chest physiotherapy act on newborn babies suffering from bronchiolitis

Despite the lack of studies, chest physiotherapy (CPT) is widely used for newborn babies suffering from bronchiolitis. The limited data regarding this technique is mainly due to the difficulties making in situ measurements during the act. In the presented study, original instrumented gloves were designed and realized to perform measurements on babies during the CPT act. Custom-designed associated electronics and software were specially developed to monitor and record the forces applied by the physiotherapist's hands on the infant's chest and their trajectories. A prospective study, with babies in real situation, validates the principle measurement. Measurements with the system was led on babies in a referent physiotherapist consulting room between January and March 2007. The results are being analyzed and typical phases of the CPT act are highlighted.

[Rib fractures after chest physiotherapy: a report of 2 cases]

The 2000 French consensus conference for acute viral bronchiolitis management underlined the fundamental role of chest physiotherapy. According to Chalumeau and al., rib fractures were found out in 1/1000 children hospitalized for bronchiolitis or pneumonia. However, such complication of chest physiotherapy is exceptional. We report 2 cases with third to sixth lateral rib fractures after chest physiotherapy in infants with bronchiolitis. Despite the rarity of these complications, clinicians must keep in mind this etiology while facing rib fractures in infants.

Hypothesis: fetal movement influences fetal and infant bone strength

Infants who present with multiple unexplained fractures in which there is no prior trauma, no radiographic evidence of metabolic bone disease, and no biochemical evidence of metabolic bone disease are almost always diagnosed as victims of child abuse, even though parents and caregivers deny wrongdoing. Such a diagnosis has far reaching implications for the infant and family. This article describes the clinical features of 65 such infants with multiple unexplained fractures in which the parents and caregivers deny wrongdoing and in which child abuse was diagnosed. These infants have the phenotype of temporary brittle bone disease that was described by Paterson. A striking observation in these young infants is the pregnancy history of decreased fetal movement. A hypothesis is suggested as an alternative explanation for the mechanism of these fractures in these infants--namely temporary brittle bone disease from fetal immobilization. This hypothesis states that fetal bone loading through fetal movement is essential for the formation of bones of normal strength. This hypothesis is an application of Frost's mechanostat/bone-loading model of bone physiology to the prenatal period of bone formation. This hypothesis explains many of the other observations about temporary brittle bone disease including the early onset of the fractures in the first several months of life, the lack of bruising, the lack of other internal organ injury, and the low risk profile of many of the parents for committing child abuse.

SELECTION CRITERIA

Randomised controlled trails (RCTs) in paediatric patients younger than twenty four months old in which chest physiotherapy was compared against no intervention or against another type of physiotherapy.

DATA COLLECTION AND ANALYSIS

Two independent reviewers extracted the data. Primary outcome was a severity clinical score. Secondary outcomes were length of hospital stay, duration of oxygen supplementation, and the use of bronchodilators and steroids.

AUTHORS' CONCLUSIONS

Based on the results of three RCTs, chest physiotherapy using vibration and percussion techniques does not reduce length of hospital stay, oxygen requirements, or improve the severity clinical score in infants with acute bronchiolitis that are not under mechanical ventilation, and who do not have any other co-morbidity. Chest physiotherapy using forced expiratory technique needs to be evaluated by clinical research.

The lesson of temporary brittle bone disease: all bones are not created equal

Temporary brittle bone disease (TBBD) is a recently described phenotype of multiple, unexplained fractures in the first year of life and predominantly in the first 6 months of life. There is usually no other injury such as bruising, subdural hematomas, retinal hemorrhages, or other internal organ injury. The susceptibility to fracture is transient, and there are no other radiographic or biochemical abnormalities noted in the standard evaluation that might suggest an underlying cause. The child abuse and pediatric radiology communities have, for the most part, been unwilling to accept this as a real condition, for they believe it is a ruse for child abuse. This review describes the experience of the author in evaluating infants with multiple unexplained fractures and the hypothesis that has emerged for explaining TBBD. The hypothesis is a prenatal application of the mechanostat/bone loading theory of bone formation and states that TBBD is caused by fetal immobilization which leads to fetal bone unloading and transient, relative osteopenia. Such susceptible infants can fracture with routine handling and present with a pattern of fractures that is similar to that which has been thought to be highly specific for child abuse. The review presents: (a) the evidence that indicates that normal fetal movement is important for normal fetal bone strength, (b) a critique of the radiologic approach in the diagnosis of child abuse in infants with multiple unexplained fractures, (c) observations that would indicate that child abuse is unlikely in infants with TBBD, and (d) new approaches to the infant with multiple unexplained fractures that would assist in accurate diagnosis.
