Can We Improve Antifungal Susceptibility Testing?

Systemic antifungal agents are increasingly used for prevention or treatment of invasive fungal infections, whose prognosis remains poor. At the same time, emergence of resistant or even multi-resistant strains is of concern as the antifungal arsenal is limited. Antifungal susceptibility testing (AFST) is therefore of key importance for patient management and antifungal stewardship. Current AFST methods, including reference and commercial types, are based on growth inhibition in the presence of an antifungal, in liquid or solid media. They usually enable Minimal Inhibitory Concentrations (MIC) to be determined with direct clinical application. However, they are limited by a high turnaround time (TAT). Several innovative methods are currently under development to improve AFST. Techniques based on MALDI-TOF are promising with short TAT, but still need extensive clinical validation. Flow cytometry and computed imaging techniques detecting cellular responses to antifungal stress other than growth inhibition are also of interest. Finally, molecular detection of mutations associated with antifungal resistance is an intriguing alternative to standard AFST, already used in routine microbiology labs for detection of azole resistance in Aspergillus and even directly from samples. It is still restricted to known mutations. The development of Next Generation Sequencing (NGS) and whole-genome approaches may overcome this limitation in the near future. While promising approaches are under development, they are not perfect and the ideal AFST technique (user-friendly, reproducible, low-cost, fast and accurate) still needs to be set up routinely in clinical laboratories.

Improving the quality of written information available at weekends in a paediatric hospital: the TRANSMIT sheet.

The clinical outcomes at weekends are worse than during the week in a hospital setting. There are many potential factors which influence this. High quality communication between the weekday teams and the on call weekend staff could help improve clinical outcomes at weekends, but there are no validated forms of communication that have been established in a paediatric hospital setting. The casenotes of all medical patients (n=119) were prospectively evaluated across all medical wards in a large paediatric hospital over three weekends, to establish the quality of information available to on call teams. Following introduction of structured documentation, known as a TRANSMIT (including Tasks, Respiratory, Anticipated problems, Nutrition, Sepsis, Medication, Intravenous access, Transfer/discharge) sheet, the audit was repeated (n=111). A qualitative survey of junior doctors using TRANSMIT was carried out after introduction. Prior to the introduction of the structured documentation (TRANSMIT sheet) an accurate problem list was present in 56% (67/119), and an adequate written management plan in 63% (75/119). Following introduction, an improvement in the notes was seen, with accurate problem lists in 82% (91/111) and an adequate plan in 76% (84/111). Improvements in the quantity and quality of information available to weekend on call medical staff were noted. The use of a structured documentation (TRANSMIT sheet) can improve the quality of written information available to on-call teams in a paediatric hospital setting. A retrospective qualitative assessment of junior doctors using TRANSMIT sheets showed an improvement in both the quantity and quality of information available to on call staff at weekends.

Decreased pediatric hospital mortality after an intervention to improve emergency care in Lilongwe, Malawi.

BACKGROUND AND OBJECTIVE: Emergently ill infants and children are often inadequately recognized and stabilized by health care facilities in the developing world. This deficiency contributes to high inpatient mortality rates, particularly early during hospitalization. Our referral hospital in Lilongwe, Malawi, experiences high volume, acuity, and mortality rates. The entry point to our hospital for most children presenting with acute illness is the Under-5 Clinic. We hypothesized that early inpatient mortality and total inpatient mortality rates would decrease with an intervention to prioritize and improve pediatric emergency care at our hospital. METHODS: We implemented the following changes as part of our intervention: (1) reallocation of senior-level clinical support from other areas of the hospital to the Under-5 Clinic for supervision of emergency care, (2) institution of a formal triage process that improved patient flow, and (3) treatment and stabilization of patients before transfer to the inpatient ward. We compared early inpatient and total inpatient mortality rates before and after the intervention. RESULTS: After the intervention, early mortality decreased from 47.6 to 37.9 deaths per 1000 admissions (relative risk 0.80, 95% confidence interval 0.67-0.93). Total mortality also decreased from 80.5 to 70.5 deaths per 1000 admissions after the intervention (relative risk 0.88, 95% confidence interval 0.78-0.98). CONCLUSIONS: Simple, inexpensive interventions to improve pediatric emergency care at this underresourced hospital in sub-Saharan Africa were associated with decreased hospital mortality rates. The description of this process and the associated results may influence practice and resource allocation strategies in similar clinical environments.

Severe Clostridium difficile colitis and reactive arthritis in a ten-year-old child.

We present a case of Clostridium difficile associated colitis in a 10-year-old girl; following 2 consecutive courses of oral antibiotics she developed severe diarrhea and a hip effusion. This is the fourth published pediatric case of C. difficile associated reactive arthritis. C. difficile toxins A and B were isolated from stool culture. She made a full recovery following metronidazole therapy.
