Spectrum of bactericidal action of amylmetacresol/2,4-dichlorobenzyl alcohol lozenges against oropharyngeal organisms implicated in pharyngitis.

Int J Gen Med 2018 28;11:451-456. Epub 2018 Nov 28.

Reckitt Benckiser Healthcare International Ltd, Slough, Berkshire, UK,

Purpose: Pharyngitis is commonly caused by a self-limiting upper respiratory tract infection (URTI) and symptoms typically include sore throat. Antibiotics are often inappropriately used for the treatment of pharyngitis, which can contribute to antimicrobial resistance, therefore non-antibiotic treatments which have broad antiseptic effects may be more appropriate. Amylmetacresol (AMC) and 2,4-dichlorobenzyl alcohol (DCBA) are present in some antiseptic lozenges and have established benefits in providing symptomatic relief and some in vitro antiviral action.

Acute infections of the upper respiratory tract and upper gastrointestinal tract (mouth and throat) are still the most common reason for reporting to the general practitioner or ENT specialist. Despite the fact that the most common causative agent of these diseases is a virus, antibiotics are still flavored in about 60-80% of patients who report to the doctor. In consensuses such as EPOS, WHO reports and other local/ / national reports, there is a need to limit antibacterial treatment for and to replace it with symptomatic and anti-inflammatory drugs.

Acute rheumatic fever.

Lancet 2018 07 29;392(10142):161-174. Epub 2018 Jun 29.

Heart Institute (InCor), University of São Paulo, Institute for Investigation in Immunology, National Institute of Science and Technology, São Paulo, Brazil.

Acute rheumatic fever is caused by an autoimmune response to throat infection with Streptococcus pyogenes. Cardiac involvement during acute rheumatic fever can result in rheumatic heart disease, which can cause heart failure and premature mortality. Poverty and household overcrowding are associated with an increased prevalence of acute rheumatic fever and rheumatic heart disease, both of which remain a public health problem in many low-income countries.

Neutralization of Streptolysin S-Dependent and Independent Inflammatory Cytokine IL-1β Activity Reduces Pathology During Early Group A Skin Infection.

Front Cell Infect Microbiol 2018 3;8:211. Epub 2018 Jul 3.

Department of Biological Sciences, University of Notre Dame, Notre Dame, IN, United States.

The bacterial pathogen Group A (GAS) has been shown to induce a variety of human diseases ranging in severity from pharyngitis to toxic shock syndrome and necrotizing fasciitis. GAS produces a powerful peptide toxin known as Streptolysin S (SLS). Though long recognized as a potent cytolysin, recent evidence from our lab has shown that SLS-dependent cytotoxicity is mediated through activation of the pro-inflammatory mediators p38 MAPK and NFκB.

Frequency of Treatment Switching for Spironolactone Compared to Oral Tetracycline-Class Antibiotics for Women With Acne: A Retrospective Cohort Study 2010-2016.

J Drugs Dermatol 2018 Jun;17(6):632-638

Background: Long-term oral antibiotic use in acne may be associated with a variety of adverse effects including antibiotic resistance, pharyngitis, inflammatory bowel disease, and breast and colon cancer. Spironolactone may represent an effective and safe alternative to oral antibiotics for women with moderate to severe acne, however comparative studies are lacking.

Methods: Using the OptumInsight™ Clinformatics™ DataMart, we conducted a retrospective analysis of the frequency of switching to a different systemic agent within the first year of therapy among women with acne who were started on either spironolactone or an oral tetracycline-class antibiotic between 2010-2016, after controlling for age, topical retinoid, and oral contraceptive use.

Taking heed of the 'danger space': acute descending necrotising mediastinitis secondary to primary odontogenic infection.

BMJ Case Rep 2018 May 30;2018. Epub 2018 May 30.

Radiology, Fiona Stanley Hospital, Murdoch, Australia.

Descending necrotising mediastinitis (DNM) is an uncommon clinical entity which may arise secondary to primary odontogenic or neck infection in susceptible patients. Infection may spread contiguously via the alar or 'danger' space, a potential anatomical space posterior to the true retropharyngeal space. Spread of infection to the mediastinum almost always necessitates urgent cardiothoracic surgical intervention. Read More
