Ciprofloxacin (CPX), a second generation fluoroquinolone antibiotic, is used as a primary antibiotic for treatment against gastroenteritis, drug-resistant tuberculosis, and malignant otitis externa. CPX is a broad spectrum antibiotic that targets the DNA gyrase of both Gram-positive and Gram-negative bacteria. Irrational and improper usage of CPX results in emergence of CPX resistant organisms emphasizing the importance of using lethal doses of CPX. Read More

A Cross-Sectional Study of Veterinarians in Germany on the Impact of the TÄHAV Amendment 2018 on Antimicrobial Use and Development of Antimicrobial Resistance in Dogs and Cats.

Antibiotics (Basel) 2022 Apr 5;11(4). Epub 2022 Apr 5.

Institute of Pharmacology and Toxicology, Department of Veterinary Medicine, Freie Universität Berlin, Koserstraße 20, 14195 Berlin, Germany.

To minimize the use of third- and fourth-generation cephalosporins and fluoroquinolones, the 2018 amendment to the regulations of veterinary pharmacies (TÄHAV) introduced legal restrictions in Germany. In an online survey among German veterinarians, we investigated the influence of these requirements on the use of antibiotics in the treatment of dogs and cats and the development of resistance rates. It was found that, on average, between 21% and 30% of daily treated dogs and cats received antimicrobial therapy. Read More

Utility of Temporal Bone Computed Tomography in Pediatric Emergency Medicine.

West J Emerg Med 2022 Feb 9;23(2):238-245. Epub 2022 Feb 9.

The Pennsylvania State University, College of Medicine, Department of Otolaryngology - Head and Neck Surgery, Hershey, Pennsylvania.

Objective: Temporal bone computed tomography (CT) requires a relatively high radiation dose to produce high-resolution images required to define surgical anatomy. In the acute setting, the need for this detailed evaluation of temporal bone pathology may not be required for nonsurgical management and clinical decision-making. We performed a retrospective review of the clinical characteristics and subsequent management of children who underwent CT of the temporal bone with the goal of optimizing clinical decision-making and mitigating the risks of radiation exposure in children.

Brachycephaly in French bulldogs and pugs is associated with narrow ear canals.

Vet Dermatol 2022 Jun 16;33(3):214-e60. Epub 2022 Mar 16.

Small Animal Department, College of Veterinary Medicine, University of Leipzig, Leipzig, Germany.

Background: Brachycephalic dog breeds have multiple skull malformations which may lead to anatomical changes in the external auditory canal. It is our frequent observation that in the otoscopic examination of the external ear in these breeds we are unable to visualise the tympanic membrane as a consequence of extreme narrowing of the proximal ear canal. Additionally brachycephalic dogs reportedly are predisposed to otitis externa (OE) and otitis media. Read More

Instituto de Investigación en Discapacidades Neurológicas (IDINE) University of Castilla-La Mancha Albacete Spain.

Objective: The purpose of this study was to evaluate the in vitro antibacterial effects of a Cymene-based bis(pyrazolyl)methane derivative (SC-19) to advance in developing alternative therapeutic compounds to fight against bacterial isolates from patients with otitis externa (OE).

Methods: Eighteen swab specimens were collected from patients aged over 18 years diagnosed with OE within at least 7 days of symptom onset, contaminated by only one bacterium type: ( = 5); ( = 8); ( = 2); ( = 1); ( = 2). To appraise antibacterial activity, minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), minimum biofilm inhibitory concentration (MBIC), and minimum biofilm eradication concentration (MBEC) assays were run at different SC-19 concentrations.

Comparison of the clinical outcome of endoscopic push-through myringoplasty and microscopic overlay myringoplasty: matching co-variated designs.

BMC Surg 2022 Feb 11;22(1):44. Epub 2022 Feb 11.

Skull Base Surgery Unit, Department of Otorhinolaryngology, Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand, 40002.

Background: The conventional microscopic overlayer myringoplasty is preferred because it allows a both hands technique, not reducing middle ear space, increasing the blood supply in the repaired area, and providing graft support; however, this technique may be troublesome for the novice surgeon during tympanomeatal flap elevation. Recently, the endoscopic push-through myringoplasty technique has developed. It provides better visualization of the hidden areas and does not require raising tympanomeatal flap. Read More

Prevalence of Infectious Diseases Among 6078 Individuals With Down Syndrome in the United States.

J Patient Cent Res Rev 2022 17;9(1):64-69. Epub 2022 Jan 17.

Advocate Aurora Health, Downers Grove, IL.

A recent disease prevalence study of the largest documented Down syndrome (DS) cohort in the United States strongly suggested significant disparity in general infectious disease conditions among individuals with DS versus those without DS. In this follow-up retrospective analysis, we explored these differences in greater detail by calculating prevalence of 52 infectious diseases, across 28 years of data among 6078 individuals with DS and 30,326 age- and sex-matched controls, abstracted from electronic medical records within a large Midwestern health system. We found that the DS cohort had higher prevalence of pneumonias (including aspiration, viral, bacterial, pneumococcal, and unspecified/atypical); otitis externa; and the skin infections impetigo, abscess, and cellulitis.
