The clinical efficacy, safety and bacteriological eradication of Group A beta-haemolytic streptococci (GABHS) from the throat was studied after treatment of streptococcal tonsillopharyngitis with three commonly used oral antibiotics in a prospective, open labelled, comparative, randomised trial of 265 evaluable patients seen in one centre. All three antibiotics were administered in the recommended doses; penicillin V q8 hourly and clarithromycin q12 hourly were given for 10 days and cefprozil q12 hourly for 5 days. Clinical results and adverse events were similar for all three antibiotics used, with a prompt clinical outcome of >95%. Cefprozil had the best bacteriological eradication rate (failed to eradicate: 13.2, 15.1, 2.3; relapses: 13.2, 11.4, 5.7%, for penicillin, clarithromycin and cefprozil, respectively). Oral penicillin remains a clinically effective and safe antibiotic for the treatment of streptococcal pharyngitis. However, compliance and convenience for parents and children when they are asked to follow a 10 days course, especially when the patient has improved from the second or third day, together with the high incidence of bacteriological eradication failures, is an issue.

This study explored the relationship between serum vitamin C levels, antioxidant defense mechanisms, and the severity of pulmonary tuberculosis (TB) among Romanian patients. This study enrolled 53 patients with bacteriologically confirmed pulmonary tuberculosis at Victor Babes University Hospital in Craiova between January 2023 and August 2024. Participants were stratified into two groups based on their serum vitamin C levels: 26 patients with normal levels and 27 patients with low levels.

Article Synopsis
  • Melioidosis, caused by Burkholderia pseudomallei, can evade detection and often gets misdiagnosed as other infections, resulting in incorrect treatment.
  • A case study highlights a middle-aged diabetic man who was mistakenly diagnosed with tuberculosis instead of melioidosis after multiple symptoms including high fever and joint swelling.
  • Effective treatment required a specific antibiotic regimen (meropenem and cotrimoxazole) over several weeks, demonstrating the importance of accurate identification to ensure the right medication is administered.

Bacteriophage therapy as an innovative strategy for the treatment of Periprosthetic Joint Infection: a systematic review.

Int Orthop

November 2024

Department of Orthopedic Surgery and Sport Medicine, FIFA Medical Center of Excellence, Croix-Rousse Hospital, Lyon University Hospital, Lyon, France.

Background: Periprosthetic Joint Infection (PJI) following hip and knee arthroplasty is a catastrophic complication in orthopaedic surgery. It has long been a key focus for orthopaedic surgeons in terms of prevention and management. With the increasing incidence of antibiotic resistance in recent years, finding more targeted treatment methods has become an increasingly urgent issue.

The evidence base for the optimal antibiotic treatment duration of upper and lower respiratory tract infections: an umbrella review.

Lancet Infect Dis

January 2025

Department of Internal Medicine, Division of Infectious Diseases, Amsterdam University Medical Center, University of Amsterdam, Amsterdam, Netherlands. Electronic address:

Article Synopsis
  • An umbrella review was conducted to evaluate existing evidence on optimal antibiotic treatment durations for various respiratory tract infections, focusing on whether shorter courses are as effective as longer ones.
  • The review included systematic reviews of conditions like community-acquired pneumonia and acute sinusitis, assessing factors like clinical outcomes and the quality of the studies using established criteria.
  • Findings indicated that most systematic reviews were of low quality, but there was some support for a 5-day treatment duration for community-acquired pneumonia and acute exacerbation of chronic obstructive pulmonary disease; however, reliable evidence for other conditions and shorter durations is lacking.

To evaluate the efficacy of SWEEPS mode of the Er: YAG laser(SL) and passive ultrasonic irrigation(PUI) in the eradication of microorganisms and in the inflammation detection by IL-1β. Thirty patients with chronic apical periodontitis(AP) were allocated into two groups: Group SL-SWEEPS laser activated irrigation(n = 15) and Group PUI-passive ultrasonic irrigation(n = 15). Bacteriological samples were taken before(S1) and after chemomechanical preparation(S2), and then after final irrigation activation(S3).
