Treatment of multidrug resistant tuberculosis (MDR-TB) is lengthy, toxic, expensive, and has generally poor outcomes. We undertook an individual patient data meta-analysis to assess the impact on outcomes of the type, number, and duration of drugs used to treat MDR-TB.

BACKGROUND
Compared to high-income settings, survival in burn units in low-income settings is lower with invasive infections one leading cause of death. Médecins Sans Frontières is involved in the treatment of large burns in adults and children in Haiti.
METHODS
In 2014, we performed a review of 228 patients admitted consecutively with burn injury during a 6-month period to determine patient outcomes and infectious complications. Microbiology was available through a linkage with a Haitian organization. Regression analysis was performed to determine covariates associated with bloodstream infection and mortality.
RESULTS
102 (45 %) patients were male, the median age was 8 years (IQR, 2-28), and the majority of patients (60 %) were admitted to the unit within 6 h of injury. There were 20 patients (9 %) with culture-proven bacteremia. Among organisms in blood, common isolates were Staphylococcus aureus (42 %), Pseudomonas aeruginosa (23 %), and Acinetobacter baumannii (15 %). Among patients with burns involving <40 % total body area, 4 (2 %) of 192 died and 20 (65 %) of 31 with ≥40 % body surface area involvement died. Factors associated with mortality included involvement of ≥40 % of body surface, depth, and flame as the mechanism. Multidrug-resistant infections were common; 18 % of S. aureus isolates were methicillin resistant, and 83 % of P. aeruginosa isolates were imipenem resistant.
CONCLUSIONS
A low mortality rate was observed in a humanitarian burn surgery project in patients with burns involving <40 % of total body surface. Invasive infection was common and alarming rates of antibiotic resistance were observed, including infections not treatable with antibiotics available locally.

The epidemiology of surgical site infections (SSIs) in surgical programmes in sub-Saharan Africa is inadequately described. We reviewed deep and organ-space SSIs occurring within a trauma project that had a high-quality microbiology partnership and active follow-up. Included patients underwent orthopaedic surgery in Teme Hospital (Port Harcourt, Nigeria) for trauma and subsequently developed a SSI requiring debridement and microbiological sampling. Data were collected from structured chart reviews and programmatic databases for 103 patients with suspected SSI [79% male, median age 30 years, interquartile range (IQR) 24-37]. SSIs were commonly detected post-discharge with 58% presenting >28 days after surgery. The most common pathogens were: Staphylococcus aureus (34%), Pseudomonas aeruginosa (16%) and Enterobacter cloacae (11%). Thirty-three (32%) of infections were caused by a multidrug-resistant (MDR) pathogen, including 15 patients with methicillin-resistant S. aureus. Antibiotics were initiated empirically for 43% of patients and after culture and sensitivity report in 32%. The median number of additional surgeries performed in patients with SSI was 5 (IQR 2-6), one patient died (1%), and amputation was performed or recommended in three patients. Our findings suggest the need for active long-term monitoring of SSIs, particularly those associated with MDR organisms, resulting in increased costs for readmission surgery and treatment with late-generation antibiotics.
