Peritonsillar abscess is a localised infection in the peritonsillar space. Pus from the abscess can contain anaerobes. Many clinicians prescribe metronidazole in addition to penicillin, but evidence to support this is limited. This review assessed the evidence of benefit of metronidazole for the treatment of peritonsillar abscess.

A systematic review was conducted of the literature and databases including Ovid Medline, Ovid Embase, PubMed and Cochrane library. Search terms included all variations of peritonsillar abscess, penicillin and metronidazole.

Three randomised, control trials were included. All studies assessed the clinical outcomes after treatment for peritonsillar abscess, including recurrence rate, length of hospital stay and symptom improvement. There was no evidence to suggest additional benefit with metronidazole, with studies suggesting increased side effects.

Evidence does not support the addition of metronidazole in first-line management of peritonsillar abscess. Further trials to establish optimum dose and duration schedules of oral phenoxymethylpenicillin would benefit clinical practice.

Urinary tract infections (UTIs) are common in general practice, and antibiotic resistance is often seen. Urine cultures are advised by the Dutch national UTI guideline for patients at high risk of UTI complications. Prudent use of antibiotics and taking into account national guidelines and urine culture results are important to combat antibiotic resistance in general practice.

To identify subgroups of UTI patients in which the use of urine cultures and antibiotic prescriptions deviates from the national guidelines.

We investigated associations of several characteristics with urine culture orders in patients with UTI in 2015 from seven Dutch general practices (n=1295). These included subgroups at risk for UTI complications, comorbidities, age and history of UTI recurrence. In addition, we assessed the level of adherence to the guideline for antibiotic prescriptions in subgroups at risks for UTI complications.

Urine cultures were ordered in 17% (n=221) of patients, more frequently in high-risk patients (32%) than in low-risk patients (7%), for UTI complications (OR=6.4; 95% CI 4.6–9.0). In low-risk patients, 91% received antibiotics that were recommended in the guideline. For high-risk patients this percentage ranged widely, and was particularly low in the risk groups with signs of tissue invasion (29–50%). Diagnostic and therapeutic adequacy can still be improved by increasing the adherence to the guideline in UTI patients at high risk for complications. This may contribute to containing antibiotic resistance in UTI by ordering urine cultures and use the results to adjust prescriptions to antibiotic susceptibility of the uropathogen.

To perform a review and meta-analysis on the effect of antibiotics on treatment of skin and soft tissue abscesses (SSTAs) after incision and drainage.

We searched MEDLINE, EMBASE, Web of Knowledge, and Google Scholar databases to identify randomized controlled trials (RCTs) and observational studies. For RCTs, we included studies comparing any antibiotic (treatment) to placebo (control). For observational studies, treatment was the use of appropriate antibiotics effective against bacterial isolate, and control was the use of inappropriate (ineffective) or no antibiotics. Outcome was treatment success during follow-up. Two investigators reviewed records, assessed quality (according to Cochrane and Newcastle-Ottawa tools), and extracted treatment success rates. Primary analysis was the effect of treatment among RCTs. Secondary analyses included the effect of treatment in 1) observational studies of confirmed methicillin-resistant Staphylococcus aureus (MRSA) infection (MRSA-only) and 2) all studies after 1998 (MRSA-era). We used random effects modelling, except when no heterogeneity was present when we used fixed effects.

We screened 1,968 records. Twelve were included (five RCTs, seven observational studies), representing 1,969 subjects. Seven enrolled from emergency departments, two from surgical clinics, and three from ambulatory clinics. Three enrolled children only. Pooled relative risk (RR) of treatment success among RCTs was 1.03 (95% confidence interval [CI] 0.97−1.08). Pooled RR in the secondary analyses was 1.05 (95% CI 0.96−1.15) in MRSA-only and 0.99 (95% CI 0.98−1.01) in MRSA-era.

Despite limitations in pooling available data, there is no clear evidence to support antibiotic use in treating uncomplicated SSTAs.

To determine the long-term outcome for children treated for recurrent epistaxis, and to compare the efficacy of antiseptic cream treatment and nasal cautery.

Retrospective analytical cohort study of 88 children treated for recurrent epistaxis in 2001.

Five-year data on chlorhexidine–neomycin cream usage, nasal cautery, current epistaxis frequency and emergency room attendance was collected by telephone interview and case record review.

During their first clinic visit, 51 per cent of the children had been treated with cautery and cream and 35 per cent with cream alone; 14 per cent had received no treatment. Five years later, 65 per cent of these children were still having ongoing epistaxis. Those who had undergone cautery and received cream had the highest ongoing bleeding rate (77 per cent).

The majority of children treated at our clinic for recurrent epistaxis had ongoing bleeding five years later. Despite the proven short-term efficacy of chlorhexidine–neomycin cream, few patients receive further courses of cream or are referred back to the clinic.
