Renewed interest in CoT for skin and soft tissue infections, in particular impetigo and S. pyogenes infections, has occurred in the setting of potential overestimation of the rates of S. pyogenes resistance historically (Bowen et al., 2012). In a randomized controlled noninferiority trial of indigenous Australian children aged 3 months to 13 years with purulent or crustered impetigo, CoT (TMP, 4 mg/kg twice daily for 3 days, or TMP, 8 mg/kg daily for 5 days) was compared with i.m. benzathine benzylpenicillin, and CoT was found to be noninferior (Bowen et al., 2014). However, the addition of CoT to outpatient cephalexin therapy in a cohort of patients with cellulitis without abscesses was found to have no additional benefit (Pallin et al., 2013). CoT can be used as an alternative to i.m. penicillin for impetigo; however, combination therapy with other streptococcal-active agents (e.g. cephalexin) does not appear warranted.
Case 13: Loss of Vision and a Maculopapular Rash
Layne Kerry, Janice Rymer in 100 Diagnostic Dilemmas in Clinical Medicine, 2017
A lumbar puncture was planned but not performed. Over the next 24–48 hours, the patient developed a maculopapular rash covering his limbs, abdomen and torso. This was initially thought to represent a drug reaction, possibly related to the aciclovir, but, as the rash progressed, the ophthalmology consultant advised that the rash was consistent with secondary syphilis. Blood tests were sent for syphilis serology and Treponema pallidum antibodies were detected (RPR titre of 1:32, consistent with active syphilis infection). The patient commenced intramuscular benzathine benzylpenicillin treatment.

Our analysis showed fewer additional primary physician visits and complications associated with penicillin-V treatment compared to other antibiotics. A reduced number of complications was seen with amoxicillin use, even compared to penicillin-V. Penicillins in general were associated with better outcomes than macrolide or cephalosporin treatment. IM benzathine benzylpenicillin treatment was associated with increased additional primary physician visits and the greatest number of complications, followed by amoxicillin with clavulanate.
