What is the workup for pneumonia?
Workup for pneumonia is essential to determine the level of severity of the disease and the treatment plan to be adopted. There are various diagnostic tools employed in the workup for pneumonia. These tools include the PSI/PORT, CURB 65 and the APACHE systems. PSI/PORT is a joint acronym for pneumonia severity index/patient outcome research team score, CURB-65 is also an acronym for confusion, uremia, respiratory rate, blood pressure, and age >65. These indices are measured and used to categorize the patients into groups of varying disease severity and treatment plans. APACHE stands for Acute Physiology And Chronic Health Evaluation, which takes into consideration several laboratory indices for matching disease severity with the appropriate treatment plans.
What is the most common cause of death in the United States?
Acute lower respiratory tract infection s are the most frequent infective causes of death in the United States. This group of infections is also associated with a greater morbidity than any other disease worldwide. However, there are statistical variations in the prevalence of the disease and the causative pathogens between countries and geographic regions, thereby limiting data on worldwide epidemiological studies of the disease.
What is the best way to diagnose pneumonia?
Direct means of obtaining diagnostic material in patients with pneumonia include percutaneous lung aspiration, transbronchial lung biopsy, video-assisted thoracoscopy, and open lung biopsy. These procedures are usually reserved for cases of severe pneumonia in impaired hosts and in pediatric populations, in whom sputum is not routinely available.
Why is pneumonia important?
Acute pneumonia is an important cause of morbidity and mortality worldwide. While the majority of cases of acute community acquired pneumonia (CAP) are due to bacteria, especially Streptococcal pneumoniae and less commonly the atypical organisms, respiratory tract viruses also contribute to a substantial proportion.
Why is pneumonia so common in tropical countries?
The higher incidence of pneumonia in tropical countries is primarily due to immunocompromise due to HIV infection but is also due to increased carriage of pneumococci by children and adults, large family size, crowding in small houses, exposure to domestic and tobacco smoke and the impaired immunity due to poor diet and parasitic diseases. Individuals with increased susceptibility to pneumonia include those with reduced splenic function (sickle cell disease, post-splenectomy), pregnant women, patients with diabetes mellitus and those with excess alcohol intake. Bacterial pneumonia may be preceded by a viral infection such as influenza that damages mucosal defence mechanisms.
What is AFOP in respiratory failure?
AFOP is a histopathologic pattern first reported in patients with acute respiratory failure, with predominantly basal and bilateral areas of consolidation at imaging. It is characterized by abundant fibrin deposition within the alveolar air spaces, with hyperplasia of type II pneumocytes, associated organizing-type pneumonia, and absence of hyaline membranes (which constitute the hallmark of diffuse alveolar damage). AFOP currently is considered to be a histopathologic variant of OP that may be associated with more rapid progression of disease. As with OP, AFOP may be encountered in the context of various underlying conditions, including infection.
What are the sequelae of pneumonia?
Acute pneumonia can lead to parenchymal damage and long-term sequelae. The most common sequelae of acute pneumonia are bronchiectasis and Swyer-James syndrome. Bronchiectasis is enlargement of the diameter of the bronchi that is related to damage to the bronchial walls. It is best demonstrated by high-resolution CT, where the diagnostic finding is that the bronchus in question is larger in diameter than the adjacent pulmonary artery ( Fig. 3-30 ). Swyer-James syndrome is characterized by unilateral lung hyperlucency that is thought to be secondary to a virus-induced necrotizing bronchiolitis that leads to an obliterative bronchiolitis (see Fig. 3-30 ). Radiography shows a hyperlucent and enlarged lung with a static lung volume. The pulmonary vessels are less prominent than on the normal side.

What to do if pneumonia isn't clearing?
If your pneumonia isn't clearing as quickly as expected, your doctor may recommend a chest CT scan to obtain a more detailed image of your lungs. Pleural fluid culture. A fluid sample is taken by putting a needle between your ribs from the pleural area and analyzed to help determine the type of infection.
What is a sputum sample?
A sample of fluid from your lungs (sputum) is taken after a deep cough and analyzed to help pinpoint the cause of the infection. Your doctor might order additional tests if you're older than age 65, are in the hospital, or have serious symptoms or health conditions. These may include: CT scan.
How fast can you breathe in a minute?
Your breathing is rapid (30 breaths or more a minute) You need breathing assistance. Your temperature is below normal. Your heart rate is below 50 or above 100.

Diagnosis
- Direct means of obtaining diagnostic material in patients with pneumonia include percutaneous lung aspiration, transbronchial lung biopsy, video-assisted thoracoscopy, and open lung biopsy. These procedures are usually reserved for cases of severe pneumonia in impaired hosts and in pediatric populations, in whom sputum is not routinely available. Open lung biopsy remains the …
Contraindications
- Biopsy procedures are rarely indicated in the previously well patient with acute pneumonia. The indications and usefulness of these invasive procedures remain controversial. Blind lung aspiration has provided a diagnostic yield of 30% to 82% in adults and children with diffuse lung infiltrates, although false-negative rates of up to 18% have been reported.98,123,124 Computed …
Research
- Acute pneumonia has long been considered a risk factor for NIV failure.3 A trial evaluating NIV use in heterogeneous respiratory failure showed very poor outcome in the group of patients with pneumonia, with all such patients requiring intubation.48 Another study evaluated NIV use in patients with hypoxemic respiratory failure and identified community-acquired pneumonia as a s…
Signs and symptoms
- The symptoms and signs of lobar pneumonia may be confusing. In early pneumonia, the diagnosis may have to be made in a patient with symptoms, fever and shallow tachypnoea in the absence of any auscultatory signs. The patient will often point to the place where pain occurs when asked to cough. When pleurisy is diaphragmatic, the patient may present with suspected a…
Management
- The aetiological cause of pneumonia cannot usually be determined at the bedside but a clinical assessment of severity is more important as it can be used to guide management. In particular, young patients with uncomplicated lobar pneumonia can be managed at home with oral therapy. Patients with indicators of severity (age, co-existing disease, multi-lobar disease, shock, hypoxia…
Epidemiology
- Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila also cause pneumonia in adults but are rare in Africa. In South-east Asia and northern Australia, melioidosis should be considered as a possible cause of both acute and unresolving pneumonia, especially in the debilitated or immunocompromised. Appropriate media are needed to culture the organism …
Cause
- Corynebacterium diphtheriae produces a gray pseudomembrane in the pharynx and larynx, which may lead to respiratory obstruction and sudden death. Sudden death from acute epiglottitis occurs from respiratory obstruction caused by swelling of the epiglottic folds, uvula, and vocal cords. The most common cause of acute epiglottitis in developing countries is H. influenzae (Ty…
Medical uses
- Among atypical pneumonias, mycoplasma infections respond best to a tetracycline or erythromycin; legionella infections respond to macrolides, alone or combined with rifampicin.
Treatment
- Bronchopneumonia is most frequently associated with pneumococci or haemophilus, so that amoxicillin, tetracycline or trimethoprim should be effective. More rarely, bronchopneumonia is caused by Staph. aureus, and flucloxacillin, fusidic acid or clindamycin is urgently required for treatment. Acute exacerbations of chronic bronchitis are almost invariably associated with eithe…
Classification
- AFOP is a distinct histologic type of organizing pneumonia. Another is granulomatous organizing pneumonia. It is characterized by radiologic findings of pulmonary nodules or masses and on histology by the presence of nonnecrotizing granulomas and organizing pneumonia.
Other animals
- Fibrinous lobar pneumonia, purulent peritonitis, and mesenteric lymphadenopathy are the primary lesions reported in callitrichids infected with K. pneumoniae (Gozalo and Montoya, 1991, 1992). Enteritis and hepatomegaly were reported in a colony of common marmosets by Campos et al. (1981). Purulent meningitis, consolidative pneumonia, intestinal hemorrhages, peritonitis, and ai…
Toxicity
- Fatal multisystemic infection of African green monkeys resulted in abscess formation in the abdomen, liver, lungs, skin, and CNS. Often, abdominal masses were present entrapping and adhering to loops of bowel and were histologically characterized by chronic pyogranulomatous inflammation and fibrous adhesions (Twenhafel et al., 2008).
Prognosis
- In the initial AFOP study, patients fell into one of two clinical patterns of disease. Slightly over half of patients presented with a fulminant illness progressing rapidly to death, with the remaining patients experiencing an indolent course with eventual recovery. No clinical or histologic features correlated with the eventual outcome, and an optimal therapy was not elucidated. Because the o…
