Two community-based density case-control studies were performed to assess risk factors for cholera transmission during inter-peak periods of the ongoing epidemic in two Haitian urban settings, Gonaives and Carrefour. The strongest associations were: close contact with cholera patients (sharing latrines, visiting cholera patients, helping someone with diarrhoea), eating food from street vendors and washing dishes with untreated water. Protective factors were: drinking chlorinated water, receiving prevention messages via television, church or training sessions, and high household socioeconomic level. These findings suggest that, in addition to contaminated water, factors related to direct and indirect inter-human contact play an important role in cholera transmission during inter-peak periods. In order to reduce cholera transmission in Haiti intensive preventive measures such as hygiene promotion and awareness campaigns should be implemented during inter-peak lulls, when prevention activities are typically scaled back.

A diphtheria outbreak occurred from February to November 2011 in the village of Kimba and its surrounding settlements, in Borno State, northeastern Nigeria. We conducted a retrospective outbreak investigation in Kimba village and the surrounding settlements to better describe the extent and clinical characteristics of this outbreak. Ninety-eight cases met the criteria of the case definition of diphtheria, 63 (64·3%) of whom were children aged <10 years; 98% of cases had never been immunized against diphtheria. None of the 98 cases received diphtheria antitoxin, penicillin, or erythromycin during their illness. The overall case-fatality ratio was 21·4%, and was highest in children aged 0–4 years (42·9%). Low rates of immunization, delayed clinical recognition of diphtheria and absence of treatment with antitoxin and appropriate antibiotics contributed to this epidemic and its severity.

Objective: The present study was performed to describe the operational implications of using mid-upper arm circumference (MUAC) as a single admission criterion for treatment of severe acute malnutrition in South Sudan., Design: We performed a retrospective analysis of routine programme data of children with severe acute malnutrition aged 6-59 months admitted to a therapeutic feeding programme using weight-for-height Z-score (WHZ) and/or MUAC. To understand the implications of using MUAC as a single admission criterion, we compared patient characteristics and treatment outcomes for children admitted with MUAC<115 mm (irrespective of WHZ) v. children admitted with WHZ<-3 and MUAC≥115 mm., Results: Of 2205 children included for analysis, 719 (32·6 %) were admitted to the programme with MUAC<115 mm and 1486 (67·4 %) with WHZ<-3 and MUAC≥115 mm. Children who would have been admitted using a single MUAC<115 mm criterion were more severely malnourished and more likely to be female and younger. Compared with children admitted with WHZ<-3 and MUAC≥115 mm, children who would have been admitted using MUAC<115 mm were less likely to recover (54 % v. 69 %) and had higher risk of death (4 % v. 1 %), but responded to treatment with greater weight and MUAC gains. MUAC<115 mm would have failed to identify 33 % of deaths, while 98 % were identified by WHZ<-3 alone and 100 % by MUAC<130 mm., Conclusions: The study shows that MUAC<115 mm identified more severely malnourished children with a higher risk of mortality but failed to identify a third of the children who died. Admission criteria for therapeutic feeding should be adapted to the programmatic context with consideration for both operational and public health implications.

Introduction: During January 2010, a 7.0 magnitude earthquake struck Haiti, resulting in death and destruction for hundreds of thousands of people. This study describes the types of orthopedic procedures performed, the options for patient follow-up, and limitations in obtaining outcomes data in an emergency setting., Problem: There is not a large body of data that describes larger orthopedic cohorts, especially those focusing on internal fixation surgeries in resource-poor settings in postdisaster regions. This article describes 248 injuries and over 300 procedures carried out in the Médecins Sans Frontières-Orthopedic Centre Paris orthopedic program., Methods: Surgeries described in this report were limited to orthopedic procedures carried out under general anesthesia for all surgical patients. Exclusion factors included simple fracture reduction, debridement, dressing changes, and removal of hardware. This data was collected using both prospective and retrospective methods; prospective inpatient data were collected using a data collection form designed promptly after the earthquake and retrospective data collection was performed in October 2010., Results: Of the 264 fractures, 204 were fractures of the major long bones (humerus, radius, femur, tibia). Of these 204 fractures of the major long bones, 34 (16.7%) were upper limb fractures and 170 (83.3%) were lower limb fractures. This cohort demonstrated a large number of open fractures of the lower limb and closed fractures of the upper limb. Fractures were treated according to their location and type. Of the 194 long bone fractures, the most common intervention was external fixation (36.5%) followed by traction (16.7%), nailing (15.1%), amputation (14.6%), and plating (9.9%)., Conclusion: The number of fractures described in this report represents one of the larger orthopedic cohorts of patients treated in a single center in the aftermath of the 2010 earthquake in Haiti. The emergent surgical care described was carried out in difficult conditions, both in the hospital and the greater community. While outcome and complication data were limited, the proportion of patients attending follow-up most likely exceeded expectations and may reflect the importance of the rehabilitation center. This data demonstrates the ability of surgical teams to perform highly-specialized surgeries in a disaster zone, and also reiterates the need for access to essential and emergency surgical programs, which are an essential part of public health in low- and medium-resource settings.
