Insights

Protracted bacterial bronchitis (PBB) is a common cause of chronic cough in young children. Early diagnosis and appropriate antibiotic treatment are crucial to prevent complications like bronchiectasis.

Area of Science:

  • Pediatrics
  • Pulmonology
  • Infectious Diseases

Background:

  • Chronic cough significantly impacts children's quality of life.
  • Protracted bacterial bronchitis (PBB) is a frequent cause of chronic wet cough in children under six.
  • PBB symptoms include cough worsening with postural changes and improvement with antibiotics.

Purpose of the Study:

  • To highlight the importance of considering PBB in the differential diagnosis of chronic cough in children.
  • To emphasize the standard treatment of PBB with high-dose antibiotics.
  • To underscore the risks of misdiagnosing PBB, such as progression to bronchiectasis.

Main Methods:

  • Literature review of PubMed up to December 2016.
  • Search terms included "child," "chronic cough," and "protracted bacterial bronchitis."

Main Results:

  • PBB is a common cause of chronic cough in children under six.
  • A 2-week course of high-dose antibiotics is the standard treatment for PBB.
  • Misdiagnosis can lead to delayed or incorrect treatment, potentially causing bronchiectasis.

Conclusions:

  • PBB should be a key consideration in the differential diagnosis of chronic cough in pediatric patients.
  • Timely and adequate antibiotic therapy is essential for PBB resolution and preventing long-term respiratory complications.
  • Clinicians should extend or adjust antibiotic regimens for PBB rather than frequently switching therapies.

Bacterial Transformation

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Bacterial Signaling01:30

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Bacterial RNA Polymerase00:43

Bacterial RNA Polymerase

Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Bacterial Transcription01:53

Bacterial Transcription

RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:
