Infantile chlamydial pneumonia--a review based on 115 cases

European Journal of Pediatrics
U B Schaad, E Rossi


Clinical manifestations, diagnostic studies and management of chlamydial pneumonia were reviewed in 115 infants and compared to those from 21 infants with interstitial pertussoid eosinophilic pneumonia. The identity of these two forms of subacute afebrile pneumonia is suggested. Chlamydial pneumonia is natally acquired, essentially occurs during the second and third month of life, and its frequency in the United States is surprisingly high. Gradual onset of respiratory tract symptoms, lack of possible infection from symptomatic persons, afebrile course and staccato cough represent the typical anamnesis. Presence of conjunctivitis and serous otitis is common. Distinctive diagnostic studies include slight eosinophilia (greater than or equal to 300 eosinophils/mm3), elevated serum immunoglobulins M and G, depressed PO2 and normal PCO2 in arterial blood under room air, and both interstitial infiltrates and hyperexpansion of the lungs on chest roentgenogram. Chlamydial cultures of nasopharyngeal secretions or tracheal aspirates, and determination of antichlamydial antibody titers in serum are indicated in establishing the etiology. Adequate management consists of antichlamydial chemotherapy and general supportive care, including che...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pharmacology of Proteinopathies

This feed focuses on the pharmacology of proteinopathies - diseases in which proteins abnormally aggregate (i.e. Alzheimer’s, Parkinson’s, etc.). Discover the latest research in this field with this feed.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
