[Antibiotic resistance and antibiotic consumption in a region - using the example of community-acquired urinary tract infections].

Aktuelle Urol 2021 Jun 16. Epub 2021 Jun 16.

Universitätsklinikum Gießen und Marburg GmbH, Klinik für Urologie, Kinderurologie und Andrologie, Gießen.

Background:  In sight of increasing bacterial resistances, appropriate and cautious antibiotic therapy (antibiotic stewardship) is becoming more and more important, in private practices as well. A current S3 guideline is available for the treatment of uncomplicated urinary tract infections, which recommends that regular epidemiological examinations of pathogen sensitivity are to be carried out promptly and locally. With this said, the antibiotic prescriptions of the resident doctors in Hesse were examined and compared with the sensitivity of the most important pathogens causing urinary tract infections.

Microb Drug Resist 2021 May 13;27(5):678-684. Epub 2020 Oct 13.

Wockhardt Research Centre, D4 MIDC, Aurangabad, India.

In India, multidrug resistance in community and hospital associated Gram-negative pathogens has increased sharply over the past few years. In the absence of novel oral multidrug resistant-pathogen active therapies, the therapeutic situation with regard to community infections is even more challenging. Hence, the focus is now shifting toward potentially expanding the utility of older antibiotics such as fosfomycin and nitrofurantoin beyond their approved pathogen coverage. Read More

Bacteriophage therapy for inhibition of multi drug-resistant uropathogenic bacteria: a narrative review.

Ann Clin Microbiol Antimicrob 2021 Apr 26;20(1):30. Epub 2021 Apr 26.

Department of Microbiology, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.

Multi-Drug Resistant (MDR) uropathogenic bacteria have increased in number in recent years and the development of new treatment options for the corresponding infections has become a major challenge in the field of medicine. In this respect, recent studies have proposed bacteriophage (phage) therapy as a potential alternative against MDR Urinary Tract Infections (UTI) because the resistance mechanism of phages differs from that of antibiotics and few side effects have been reported for them. Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis are the most common uropathogenic bacteria against which phage therapy has been used. Read More

CT as a Diagnostic Tool for Emphysematous Pyelitis: A Case Report.

Cureus 2021 Feb 23;13(2):e13513. Epub 2021 Feb 23.

Radiology, Dr. Ajmera Diagnostic, New Delhi, IND.

Gas forming infections of the renal collecting system occurs because of organisms like Escherichia coli, Klebsiella, and Proteus. If the gas is restricted to the collecting system, without causing involvement of the cortex, it is called emphysematous pyelitis; whereas, invasion and penetration of the cortex imply a more gruesome diagnosis of emphysematous pyelonephritis. A 59-year-old male patient, previously diagnosed with a large right renal calculus and having multiple co-morbidities presented to the surgery department with right flank pain; Double J (DJ) stenting was done to relieve the pain from colic due to obstructive renal calculi; the patient subsequently discharged without any post-procedural complications.
