Pediatric Bronchitis Diagnosis: Diagnosis and Treatment of Acute Bronchitis
Nonviral agents cause only a small part of acute bronchitis diseases, with the most common organism being Mycoplasma pneumoniae. Study findings suggest that Chlamydia pneumoniae may be another nonviral cause of acute bronchitis. The obstructive symptoms of acute bronchitis, as established by spirometric studies, are very similar to those of moderate asthma. In one study. Forced expiratory volume in one second (FEV), mean forced expiratory flow during the midst of forced vital capacity (FEF) and peak flow values declined to less than 80 percent of the predicted values in almost 60 percent of patients during episodes of acute bronchitis.
Recent Epidemiologic Findings of Serologic Evidence of C
Pneumoniae infection in adults with new-onset asthma imply that untreated chlamydial infections may have a role in the transition from the acute inflammation of bronchitis to the chronic inflammatory changes of asthma. Patients with acute bronchitis usually have a viral respiratory infection with transient inflammatory changes that create sputum and symptoms of airway obstruction. Evidence of reversible airway obstruction when not infected Symptoms worse during the work but tend to improve during vacations, holidays and weekends Persistent cough with sputum production on a daily basis for at least three months Upper airway inflammation and no evidence of bronchial wheezing Evidence of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Generally related to a precipitating event, such as smoke inhalation Evidence of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during weekends, holidays and vacations Persistent cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no signs of bronchial wheezing Signs of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Usually related to a precipitating Occasion, like smoke inhalation Asthma and allergic bronchospastic disorders, including allergic aspergillosis or bronchospasm as a result of other environmental and occupational exposures, can mimic the productive cough of acute bronchitis.
Cough Illness/Bronchitis Principles of Judicious Use of
An investigation that included six of these studies concluded that there is absolutely no evidence to support the utilization of antibiotic treatment for acute bronchitis. Three trials that used erythromycin, doxycycline, or trimethoprim/sulfamethoxasole illustrated minimal improvement in duration of cough and time lost from work in the group treated with antibiotics. The remaining four trials, including the two that the writers concluded best executed criteria for methodologic soundness, revealed no difference in outcomes between individuals who received placebo and those treated with erythromycin, doxycycline, or tetracycline.
There are no randomized, placebo-controlled antibiotic trials of children with cough illness/bronchitis just defined by sputum production; yet, several pediatric studies have assessed the utilization of antibiotics for cough illnesses, which in common practice are called bronchitis and are treated with antibiotics. None of these studies showed any benefit of antibiotic use for the cough. An evaluation of these trials concluded that antibiotics did not prevent or decrease the severity of bacterial complications subsequent to viral respiratory tract infections.
Having less benefit from antimicrobial treatment is not inconsistent with community- and hospital-based studies in the United States and other areas of the world that implicate nonbacterial organisms as the etiologic agents of cough illness/ bronchitis. Neither the nature nor the culture consequences of surrogate specimens including sputum (defined by the existence of fewer than 10 epithelial cells per high power field) or nasopharyngeal (NP) secretions is sufficiently predictive of a bacterial disease of the bronchi to be of use in defining the requirement for antimicrobial therapy.

How Is Bronchiolitis in Children Treated? - Craig Nakamura, MD - Pediatric Pulmonologist
Doctors treat bronchiolitis in children with inhaled medications, says Craig Nakamura, MD, a pediatric pulmonologist at Sunrise Hospital. In this video, he ...
Studies have evaluated the use of NP cultures to forecast the causative organism of other upper and lower respiratory tract infections, such as otitis media, sinusitis, and pneumonia, for which there are accepted standard means of obtaining specimens directly from your site of infection. Coincident cultures of the nasopharynx and middle ear fluid. Maxillary sinus fluid. Or percutaneous lung aspiration specimens25 demonstrated that NP cultures were poor predictors of the true bacterial pathogens. Some professionals use the presence of temperature in conjunction with cough to diagnose bronchitis and prescribe antibiotic treatment.4However, fever is an estimated component of cough illness/bronchitis and does not signify that cough is related to a bacterial infection or that any benefit would be derived from antimicrobial therapy.
Symptoms and Causes
For the first few days, the signs and symptoms of bronchiolitis are like those of a cold: After this, there may be a week or more of difficulty breathing or a whistling sound when the child breathes out (wheezing). This is particularly important if your child is younger than 12 weeks old or has other risk factors for bronchiolitis including premature birth or a heart or lung illness. These signs and symptoms are reasons to seek prompt medical attention: Bronchiolitis occurs when a virus infects. Babies younger than 3 months of age are at greatest risk of getting bronchiolitis because their lungs and immune systems aren't yet completely grown. More acute sickness as a result of bronchiolitis, or other factors that are correlated with a heightened risk of bronchiolitis in infants, contain: If these occur, your child may require hospitalization. Your baby was born has a lung or heart illness if, or has a compromised immune system, watch closely for beginning signs of bronchiolitis.

Acute Bronchitis in Children
Acute bronchitis may follow the common cold or other viral infections. The following are the most common symptoms for acute bronchitis: In the earlier stages of the illness, children may have a dry, nonproductive cough which progresses afterwards to an abundant mucus-filled cough. Sometimes, other tests may be done to rule out other disorders, including asthma or pneumonia: In many cases, antibiotic treatment is unnecessary to treat acute bronchitis, since viruses cause most of the infections.
