Google Scholar. , pneumon- , pneumono-. the World Health Organization [WHO], National Institutes of Health [NIH], and Harrison’s), are the most prone to heterogeneity. 15th ed. The textbook also describes that the specific microbial aetiology remains unknown in more than a third of patients, although it is common in children for a blood culture to be the only test performed to provide a specific diagnosis, which may only be positive in 5–10 % of patients and up to 20 % in the most severely ill patients [12]. World Health Organization Pneumonia Vaccine Trial Investigators’ Group. Pneumonia. Surgical patients are predisposed to developing lower respiratory tract infections due to a combination of: 1.

In epidemiologic terms, investigation of heterogeneous groups will, to a lesser or greater extent, threaten the internal validity of studies. Pneumonia should be defined as an acute infection of the lung parenchyma by one or co-infecting pathogens, but excluding the well-defined condition of bronchiolitis, the primary cause of which is almost always a viral agent. Wells EF. However, taken to an extreme, the pursuit of representativeness can defeat the goal of identifying causal biological relations. Washington: Government Printing Office; 1931. Mayo Clinic, Rochester, Minn. May 1, 2016. Pneumonia can affect anyone. It is clear that all of the systems of classification have significant deficiencies, primarily relating to an inability to determine the aetiology of cases of pneumonia, and substantial heterogeneity of aetiology, phenotype and pathology. The diagnosis of pneumonia in the intensive care setting was noted as being particularly unreliable, although the evolving use of lung ultrasound offers more clarity. Aspiration is more likely if something disturbs your normal gag reflex, such as a brain injury or swallowing problem, or excessive use of alcohol or drugs. [ nu-mōn ′yə ] An acute or chronic disease marked by inflammation of the lungs, especially an infectious disease caused by viruses, bacteria, or other pathogens, such as mycoplasmas. 3rd ed. Pneumonia definition is - an acute disease that is marked by inflammation of lung tissue accompanied by infiltration of alveoli and often bronchioles with white blood cells (such as neutrophils) and fibrinous exudate, is characterized by fever, chills, cough, difficulty in breathing, fatigue, chest pain, and reduced lung expansion, and is typically caused by an infectious agent (such as a bacterium, virus, or fungus). The nose without the pharynx or the lungs without the bronchi would be nothing more than spare parts, like on an old junker in a garage. See your doctor if you have difficulty breathing, chest pain, persistent fever of 102 F (39 C) or higher, or persistent cough, especially if you're coughing up pus. This section contains prefixes that are used for the medical terminology of most systems. Even the recent modifications to the WHO classification of childhood pneumonia fail to address the problems of poor diagnostic specificity where it is not possible to reliably differentiate between bacterial and non-bacterial pneumonia, or to always differentiate pneumonia from malaria, dehydration or acute central nervous system disorders. However, there was less agreement on how pneumonia should be defined and classified and how this issue should be tackled. To go along with these issues, there are specific medical terms that you will need to know. Pneumonia medical definition, flashcards and ICD-10 codes. Accessed April 20, 2016.

Pneumonia is an infection that inflames the air sacs in one or both lungs. Perspectives from high-income settings included the poor correlation between radiologic appearance and systems for International Classification of Disease (ICD) for hospital admissions, and an appeal for a definition that recognises certain aspects particular to older adults. Goldman L, et al., eds. The Editorial Board members who participated in the discussion would most likely agree that pneumonia is an acute infection distinguishable from chronic infections, although this should not be confused with several other acute lower respiratory tract infections with well-recognised and distinguishable patterns, such as bronchiolitis and bronchitis. Community-acquired pneumonia in children: Clinical features and diagnosis. Community-acquired pneumonia (adult). Pneumonia is an infection of the lungs caused by bacteria, viruses, fungi, or parasites. People who are on breathing machines (ventilators), often used in intensive care units, are at higher risk of this type of pneumonia. This statement is qualified, however, in that the classification of pneumonia into specific phenotypes using current or potential methods should be carefully considered when designing research studies. 2014;5:8–17. London: Sydenham Society; 1849. This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies.Most of them are combining forms in New Latin and hence international scientific vocabulary.There are a few general rules about how they combine. 2007;369:1440–51.

Effect of age, polymicrobial disease, and maternal HIV status on treatment response and cause of severe pneumonia in South African children: a prospective descriptive study. The aim of this commentary is to stimulate debate towards consensus classifications for clinical terminology, separating bronchiolitis from pneumonia, examining the value of the community- and hospital-acquired classification, and purposeful refinement of classifications based on microbiology, aetiology, radiology, severity, complications, important age groups and subgroups. Accessed April 15, 2016. Germs called bacteria, viruses, and fungi may cause pneumonia. National Heart, Lung, and Blood Institute. Article  Laennec RT. It was argued that the popular use of the term, ‘community-acquired pneumonia’ does little to advance our understanding of the condition. AskMayoExpert. Mackenzie, G. The definition and classification of pneumonia. PMID:16061709, http://dx.doi.org/10.1136/thx.2004.030411. Heterogeneous groups may result in disparate and unfocused studies, which fail to target the most important types of pneumonia and the most important questions, and make limited contributions. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia. Pneumococcal pneumonia in adults. The medical literature includes the term ‘pneumonia’ or ‘pneumonitis’ in a collection of diagnostic terms for a number of conditions that are not related to infection or have an unknown cause, which illustrates the lack of consensus in the definition of pneumonia. The study of more homogenous phenotypes is likely to provide better evidence for clinical care and more clear inference in research. Pneumonia can range in seriousness from mild to life-threatening. See our safe care and visitor guidelines, plus trusted coronavirus information. pneumonia. This site complies with the HONcode standard for trustworthy health information: verify here. Nat Med. III. Like hospital-acquired pneumonia, health care-acquired pneumonia can be caused by bacteria that are more resistant to antibiotics. Pneumonias are categorized by site and cause. The commentary then calls for debate to generate consensus classifications in the field, proposing a working definition and way forward focusing on the following three points: (i) pneumonia should be defined as an acute infection of the lung parenchyma by various pathogens, excluding the condition of bronchiolitis; (ii) defining pneumonia as a group of specific (co)infections with different characteristics is an ideal that currently has limited use, because the identification of aetiologic organisms in individuals is often not possible (however, the benefits of classifying pneumonia into specific, more homogenous phenotypes should be carefully considered when designing research studies); and (iii) investigation of more homogenous pneumonia groupings is achievable and is likely to yield more rapid advances in the field. The inclusion of more homogenous phenotypes will minimise confounding and bias.

A working definition and approach to classification is proposed to guide future research and, to a lesser extent, clinical care. Check out the following resources to support your learning and understanding of medical terminology: Quick Introduction- provides an overview and introduction to medical terminology. It is most serious for infants and young children, people older than age 65, … The problem with our current approach to the classification of pneumonia is twofold: (i) it results in widespread empirical, and often unnecessary, use of antimicrobials that contributes to pathogen resistance; and (ii) it contributes to heterogeneity among the groups of subjects compared in research, causing misclassification bias and mixtures of effects that threaten internal validity. Most pneumonia occurs when a breakdown in your body's natural defenses allows germs to invade and multiply within your lungs. Atypical pneumonias diffusely affect lung tissues rather than anatomical lobes or lobules. Two examples of pneumonia research that have substantially advanced the field illustrate the scientific benefit of using restrictive criteria to study homogenous patient subgroups. It states that pneumonia is not a single disease but a group of specific infections, each with a different epidemiology, pathogenesis, presentation and clinical course [11]. It's especially important that people in these high-risk groups see a doctor: For some older adults and people with heart failure or chronic lung problems, pneumonia can quickly become a life-threatening condition. Barson WJ. Pneumonia and your lungs. So word parts provide the meaning of myocarditis: inflammation of the heart muscle. The magnitude of the problem is less evident in the field of pneumonia research. To attain a homogeneous group of participants, research studies must classify patients according to some given criteria. Classifications of pneumonia in clinical care and research will be limited by the means available but can be made more specific using the approaches described in Table 1, and combinations thereof (Table 1 is not a complete list of all available approaches). If a specific diagnosis could be made, specific therapy could be provided which would be of similar efficacy to empiric wide spectrum therapy [13] and avoid millions of prescriptions of broad-spectrum antibiotics and the associated risks of antibiotic resistance. Or they may vomit, have a fever and cough, appear restless or tired and without energy, or have difficulty breathing and eating. Accessed April 15, 2016. To a large extent, generalisation is a question of whether the factors that distinguish populations from the study group somehow modify the effect in question. New York: SS & Wm. 25th ed. In a qualitative sense, the problem may be distilled to a lack of homogeneity in clinical and pathological phenotypes under investigation. In: Translated from the 3rd French ed. Dr Mackenzie’s article is a timely “call to arms” for clinicians and scientists to formulate a commonly agreed definition of pneumonia that will allow research to be conducted on well-defined patient groups to help optimise diagnostic strategies, develop better tests to determine aetiology, rationalise treatment and improve overall patient and community health outcomes. 2014;5:30–7. 2012;344:e3325. PubMed  Marrie TJ, et al. The ICD-10 classification of diseases has removed some of the historical descriptive terms and ‘pneumonia’ is listed as the primary term in seven codes (J12–18) but it is also a descriptive term in seven other codes relevant to specific infectious and non-infectious aetiologies, times of life and complications of diseases and procedures [10]. When heterogeneous groups are studied, invalid estimates of effect occur due to misclassification bias [14]. Overview of pneumonia. Terms and Conditions, When the prefixes are detached from a term, it is followed by a hyphen (-). Myasthenia refers to a loss of muscle strength, as in myasthenia gravis. One suggestion towards a definition of pneumonia was to take a descriptive approach: explaining anatomy and the respiratory ecosystem; describing what is meant by ‘pneumonia’; listing the causative organisms within the relevant context, and then proceeding to clinical definition(s). After outlining the problem of classification, this commentary describes the strengths and weaknesses of a range of systems for the classification of pneumonia.

Similarly, misclassification of pneumonia limits high quality epidemiological and clinical research. In: Translated from the Greek with a preliminary discourse and annotations by Francis Adams. Part of Reduced chest ventilation – reduced mobility in bedridden patients results in an inability to fully ventilate their lungs, leading to accumulation of fluid secretions which subsequently become infected 2. It needs to be considered how these two domains—public health policy for the treatment and prevention of pneumonia, and research to answer specific questions of pathogenesis, diagnosis, treatment and prevention—can better interact.

As a result, these research questions and studies may not provide clear answers. The lack of clear classification results in difficulty with clinical decision making and a potential for poorly formulated research.
