Risk factors for treatment of asymptomatic bacteriuria in a rural health system.

Purpose: Asymptomatic bacteriuria is often inappropriately treated, leading to antimicrobial-related adverse events and contributing to antimicrobial resistance. This study examined the asymptomatic bacteriuria treatment rate at a rural Wisconsin health system and the patient-specific factors that may be influencing clinicians' decisions to treat.

Methods: This is a retrospective descriptive report of patients admitted from January to May 2022 at 7 rural Wisconsin hospitals.

Sternal osteomyelitis caused by in an immunocompetent patient following coronary artery bypass surgery.

Skin commensals, especially gram-positive cocci, are the usual microbial organisms that cause post-operative sternal wound infections. Rarely, environmental bacteria such as spp. have been implicated as etiological agents in post-cardiac procedure surgical site infections.

Perianal North American blastomycosis.

Cutaneous North American blastomycosis most often results from the hematogenous spread of Blastomyces dermatitidis following pulmonary infection. Cutaneous lesions, which may be either verrucous or ulcerative plaques, commonly occur on or around orifices contiguous to the respiratory tract. We report the case of a 57-year-old man with cutaneous North American blastomycosis who presented with a well-demarcated, firm, moist, verrucous perianal plaque 4 months following the onset of a prolonged upper respiratory tract infection.

Streptococcus pyogenes sternoclavicular septic arthritis in a healthy adult.

Sternoclavicular septic arthritis is a rare infection, accounting for approximately 1% of septic arthritis in the general population. Staphylococcus aureus is the predominant etiologic agent, and it usually occurs in relatively young adults with some type of predisposition to infection. We report, to the best of our knowledge, the first case of group A streptococcal, sternoclavicular arthritis in a previously healthy 62-year-old male patient.

Bilateral prosthetic knee infection by Campylobacter fetus.

We present the first documented case of a bilateral prosthetic knee joint infection with Campylobacter fetus. Our patient's risk factors included age, the presence of prosthetic joints, and potential exposure through his contact with farm animals. It is important to be aware of the possibility of C fetus joint infections in high-risk patients who present with pain after total joint arthroplasty.

Outbreak of Burkholderia cepacia bacteremia traced to contaminated hospital water used for dilution of an alcohol skin antiseptic.

Objective: To identify the source of an epidemic of Burkholderia cepacia bloodstream infections during 7 years (411 episodes in 361 patients).

Design: Outbreak investigation.

Setting: A 250-bed university hospital in Beirut, Lebanon.
