AI Article Synopsis
- * Despite being initially treated with amoxicillin/clavulanic acid and ceftriaxone, the patient developed sepsis, indicating the treatments were ineffective.
- * Successful recovery was achieved using a combination of vancomycin and piperacillin/tazobactam, marking the first documented case of A. haemolyticum bacteremia in Argentina.
Article Abstract
We report the case of a twenty-year-old immunocompetent male patient presenting to the emergency room with pharyngitis and fever. Blood cultures were drawn and Arcanobacterium haemolyticum (rough biotype) was recovered. The presence of the arcanolysin gene was investigated at the molecular level and the upstream region was amplified and sequenced in order to correlate it with the smooth or rough biotype. Although the isolate was susceptible to penicillin, vancomycin and gentamicin, empirical treatments first with amoxicillin/clavulanic acid (1g/12h) and then with ceftriaxone (1g/12h) failed and the infection evolved to sepsis. Finally, treatment with vancomycin (1g/12h) plus piperacillin/tazobactam (4.5g/8h) was effective. Lemierre's syndrome was ruled out. To the best of our knowledge, this is the first case of bacteremia by A. haemolyticum reported in Argentina.

Background And Objectives: Leprosy foot ulcers (LFU) tend to become chronic due to secondary bacterial infections, leading to subsequent disfigurement and disability. Treatment modality for infected plantar ulcers thus so far is majorly based on conventional approach of empirical antibacterial therapy. However, this approach tends to overlook unconventional pathogens which are likely to be present in the LFU.

Article Synopsis
- * By analyzing 38 samples using advanced sequencing methods, researchers discovered a wide variety of bacteria present, with no single species being found in every sample.
- * The findings suggest that the causes of these ulcers are complex and multifactorial, highlighting the need for deeper research into the bacteria involved to improve diagnosis and treatment options in affected regions.

Article Synopsis
- The case discusses a rare instance of complications from sinusitis in a healthy 19-year-old male, leading to severe neurological issues like cerebral vasospasm and ischemia.
- Treatment involved aggressive management strategies including surgical intervention and daily catheter-directed infusions to address the complications of bacterial meningoencephalitis.
- The use of CT brain perfusion scans was crucial in diagnosing delayed cerebral ischemia, highlighting the complexity of distinguishing between cerebral vasospasm and the progression of meningoencephalitis.
