RESUMO

Several decision rules combining clinical and biological parameters have been proposed to distinguish bacterial from aseptic meningitis, but have not been evaluated in Africa. In children hospitalized with suspected central nervous system infections in Uganda, we found that the Bacterial Meningitis Score and Meningitest showed lower performance than in European children, and that a decision rule designed specifically using parameters associated with bacterial meningitis also showed inadequate diagnostic performance for clinical use.

RESUMO

Infections of the central nervous system (CNS) are severe conditions, leading to neurological sequelae or death. Knowledge of the causative agents is essential to develop guidelines for case management in resource-limited settings. Between August 2009 and October 2012, we conducted a prospective descriptive study of the aetiology of suspected CNS infections in children two months to 12 years old, with fever and at least one sign of CNS involvement in Mbarara Hospital, Uganda. Children were clinically evaluated on admission and discharge, and followed-up for 6 months for neurological sequelae. Pathogens were identified from cerebrospinal fluid (CSF) and blood using microbiological and molecular methods. We enrolled 459 children. Plasmodium falciparum (36.2%) and bacteria in CSF (13.3%) or blood (3.3%) were the most detected pathogens. Viruses were found in 27 (5.9%) children. No pathogen was isolated in 207 (45.1%) children. Patterns varied by age and HIV status. Eighty-three (18.1%) children died during hospitalisation, and 23 (5.0%) during follow-up. Forty-one (13.5%) children had neurological sequelae at the last visit. While malaria remains the main aetiology in children with suspected CNS infections, no pathogen was isolated in many children. The high mortality and high rate of neurological sequelae highlight the need for efficient diagnosis.

RESUMO

In November 1999, a Médecins Sans Frontières team based in the southeastern part of Sierra Leone reported an increased number of cases of bloody diarrhoea. Shigella dysenteriae serotype 1 (Sd1) was isolated in the early cases. A total of 4218 cases of dysentery were reported in Kenema district from December, 1999, to March, 2000. The overall attack rate was 7.5%. The attack rate was higher among children younger than 5 years than in the rest of the population (11.2% vs 6.8%; relative risk=1.6; 95% CI 1.5-1.8). The case fatality was 3.1%, also higher for children younger than 5 years (6.1% vs 2.1%; relative risk=2.9; 95% CI 2.1-4.1]). Among 583 patients regarded at increased risk of death who were treated with ciprofloxacin in isolation centres, case fatality was 0.9%. A 5-day ciprofloxacin regimen, targeted to the most severe cases of bloody diarrhoea, was highly effective. This is the first time a large outbreak caused by Sd1 has been reported in west Africa.

RESUMO

Our aim was to assess the long-term results, complications, and factors associated with failure of mandibular reconstructions among wounded Iraqi civilians with mandibular defects. Success was measured by the quality of bony union, and assessed radiographically and by physical examination. Failures were defined as loss of most or all of the bone graft, or inability to control infection. During the 6-year period (2006-2011), 35 Iraqi patients (30 men and 5 women, mean age 33 years, range 15-57) had residual mandibular defects reconstructed by iliac crest bone grafts. The causes were bullets (n=29), blasts (n=3), and shrapnel (n=3). The size of the defect was more than 5cm in 19 cases. Along the mandible the defect was lateral (n=14), central/lateral (n=5), lateral/central/lateral in continuity (n=6), and central in continuity (n=10). The mean time from injury to operation was 548 days (range 45-3814). All but 2 patients had infected lesions on admission. Bony fixation was ensured by locking reconstruction plates (n=27), non-locking reconstruction plates (n=6), and miniplates (n=2). Complications were associated with the reconstruction plate in 2 cases, and donor-site morbidity in 5. After a mean follow-up of 17 months (range 6-54), bony union was achieved in 28 (80%). The quality of the bone was adequate for dental implants in 23 cases (66%). Our results suggest that war-related mandibular defects can be reconstructed with non-vascularised bone grafts by multistage procedures with good results, provided that the soft tissues are in good condition, infection is controlled, and the method of fixation is appropriate. Further studies are needed to assess the role of vascularised free flaps in similar conditions.

RESUMO

IMPORTANCE: Little is known about the scope of practice and outcomes in pediatric surgery performed by humanitarian organizations in resource-poor settings and conflict zones. This study provides the largest report to date detailing such data for a major nongovernmental organization providing humanitarian surgical relief support in these settings. OBJECTIVE: To characterize pediatric surgical care provision by a major nongovernmental organization in specialized humanitarian settings and conflict zones. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted from August 15, 2014, to March 9, 2015, of 59,928 surgical interventions carried out from January 1, 2012, to December 31, 2013, by the Médecins Sans Frontières Operational Centre Paris (MSF-OCP) program in 20 locations, including South Sudan, Yemen, Syria, Gaza, Pakistan, Nigeria, Central African Republic, Democratic Republic of Congo, and the Philippines. Surgical interventions were primarily for general surgical, traumatic, and obstetric emergencies and were categorized by mechanism, type of intervention, American Society of Anesthesia risk classification, and urgency of intervention. MAIN OUTCOMES AND MEASURES: Operative indications, type of intervention, and operative case mortality. RESULTS: Among all age groups, 59,928 surgical interventions were performed in dedicated trauma, obstetric, and reconstructive centers for 2 years. Nearly one-third of interventions (18,040 [30.1%]) involved preteen patients (aged <13 years) and 4571 (7.6%) involved teenaged patients (aged 13-17 years). The proportion of violence-related injuries in the preteen group was significantly lower than in the teenage group (4.8% vs 17.5%; P < .001). Burns (50.1%), other accidental injuries (16.4%), and infections (23.4%) composed the bulk of indications in the preteen group. Interventions in the teenage group were principally caused by trauma-related injuries (burns, 22.9%; traffic accidents, 10.1%; gunshot wounds, 8.0%). Crude perioperative case mortality rates were 0.07% in the preteen group, 0.15% in the teenage group, and 0.22% in the adult group (>17 years) (P = .001). One-third of the cases (33.4%) were deemed urgent, while most of the remaining cases (57.7%) were deemed semielective (surgical intervention to be performed within 48 hours). CONCLUSIONS AND RELEVANCE: When examining surgical interventions in a population of pediatric patients cared for in the specialized setting of humanitarian aid and conflict zones, burns, other accidental injuries, and infection composed the bulk of indications in the preteen group; interventions in the teenage group were principally caused by trauma-related injuries. Crude perioperative case mortality rates in the preteen group were significantly lower than in the adult group. Further work is needed to examine long-term outcomes of pediatric operations in these settings and to guide context-specific surgical program development.

RESUMO

The social rejection of the polio eradication campaign in endemic countries challenges an assumption underlying the goal itself: the full compliance of an entire population to a public health programme. The polio campaign, which has been an extraordinary public health enterprise, is at risk of becoming irremediably unpopular if the eradication goal is pursued at all costs. The Global Polio Eradication Initiative (GPEI) should not be driven by the fear of failure, because the greatest benefit of the polio campaign is that it has demonstrated how simple, community-wide actions can contribute to a dramatic decrease in the incidence of a disease.

RESUMO

BACKGROUND/OBJECTIVES: The MSF programme in Jordan provides specialized reconstructive surgical care to war-wounded civilians in the region. The short musculoskeletal functional assessment score (SMFA) provides a method for quantitatively assessing functional status following orthopaedic trauma. In June 2010 the Amman team established SMFA as the standard for measuring patients' functional status. The objective of this retrospective study is to evaluate whether the SMFA scores can be useful for patients with chronic war injuries. METHODS: All patients with lower limb injuries requiring reconstruction were enrolled in the study. Each patient's SMFA was assessed at admission, at discharge from Amman and during follow-up in home country. In the analysis we compared patients with infected versus non-infected injuries as well as with both high and low admissions dysfunctional index (ADI). RESULTS: Among infected patients, higher ADI correlated with more surgeries and longer hospital stay. Infected patients with ADI >50 required an average of 2.7 surgeries while those with ADI <50, averaged 1.7 operations (p = 0.0809). Non-infected patients with ADI >50 required an average of 1.6 operations compared to 1.5 for those with ADI <50 (p = 0.4168). CONCLUSIONS: The ADI score in our sample appeared to be useful in two areas: (1) hospital course in patients with infection, where a high ADI score correlated with longer hospital stays and more surgeries, and (2) prognosis, which was better for non-infected patients who had high ADI scores. A scoring system that predicts functional outcome following surgical reconstruction of lower limb injuries would be enormously useful.

RESUMO

BACKGROUND: Early recognition of bacterial infections is crucial for their proper management, but is particularly difficult in children with severe acute malnutrition (SAM). The objectives of this study were to evaluate the accuracy of C-reactive protein (CRP) and procalcitonin (PCT) for diagnosing bacterial infections and assessing the prognosis of hospitalized children with SAM, and to determine the reliability of CRP and PCT rapid tests suitable for remote settings. METHODS: From November 2007 to July 2008, we prospectively recruited 311 children aged 6 to 59 months hospitalized with SAM plus a medical complication in Maradi, Niger. Blood, urine, and stool cultures and chest radiography were performed systematically on admission. CRP and PCT were measured by rapid tests and by reference quantitative methods using frozen serum sent to a reference laboratory. RESULTS: Median CRP and PCT levels were higher in children with bacteremia or pneumonia than in those with no proven bacterial infection (P < .002). However, both markers performed poorly in identifying invasive bacterial infection, with areas under the curve of 0.64 and 0.67 before and after excluding children with malaria, respectively. At a threshold of 40 mg/L, CRP was the best predictor of death (81% sensitivity, 58% specificity). Rapid test results were consistent with those from reference methods. CONCLUSIONS: CRP and PCT are not sufficiently accurate for diagnosing invasive bacterial infections in this population of hospitalized children with complicated SAM. However, a rapid CRP test could be useful in these settings to identify children most at risk for dying.

RESUMO

BACKGROUND: Although malnutrition affects thousands of children throughout the Sahel each year and predisposes them to infections, there is little data on the etiology of infections in these populations. We present a clinical and biological characterization of infections in hospitalized children with complicated severe acute malnutrition (SAM) in Maradi, Niger. METHODS: Children with complicated SAM hospitalized in the intensive care unit of a therapeutic feeding center, with no antibiotics in the previous 7 days, were included. A clinical examination, blood, urine and stool cultures, and chest radiography were performed systematically on admission. RESULTS: Among the 311 children included in the study, gastroenteritis was the most frequent clinical diagnosis on admission, followed by respiratory tract infections and malaria. Blood or urine culture was positive in 17% and 16% of cases, respectively, and 36% had abnormal chest radiography. Enterobacteria were sensitive to most antibiotics, except amoxicillin and cotrimoxazole. Twenty-nine (9%) children died, most frequently from sepsis. Clinical signs were poor indicators of infection and initial diagnoses correlated poorly with biologically or radiography-confirmed diagnoses. CONCLUSIONS: These data confirm the high level of infections and poor correlation with clinical signs in children with complicated SAM, and provide antibiotic resistance profiles from an area with limited microbiological data. These results contribute unique data to the ongoing debate on the use and choice of broad-spectrum antibiotics as first-line treatment in children with complicated SAM and reinforce the call for an update of international guidelines on management of complicated SAM based on more recent data.

RESUMO

OBJECTIVE: To describe medical care and surgical outcome after functional reconstructive surgery in late-presenting patients who already had at least one prior operation. DESIGN: Retrospective review of medical care and surgical outcome from August 2006 to December 2008 using patient records for initial data with active follow-up for the latest outcome information. SETTING: Médecins sans Frontières surgical programme in Jordan Red Crescent Hospital, Amman, Jordan. PATIENTS: Sixty-two civilians with nonunion tibial fractures caused by war-related trauma in Iraq; 53 completed follow-up. INTERVENTION: Amputation and/or reconstruction. MAIN OUTCOME MEASUREMENTS: Late surgical complications (after the patient's return to Iraq) were analyzed for infection recurrence, bone union, and functional condition (defined using the Short Musculoskeletal Functional Assessment score). RESULTS: Almost three fourths of patients arrived with infected injuries, 9 of whom had amputation as the initial surgery; the rest, and all uninfected patients, had reconstruction. Excluding loss to follow-up, only 4 of 53 (8%) patients who arrived with an infected injury had infection recurrence. Excluding loss to follow-up and amputation, 2 of 14 (14%) patients in the uninfected and 5 of 30 (17%) in the infected injury group did not achieve successful tibial union. Mean Dysfunctional and Bothersome Indices overall were 27.1 and 29.8, respectively, with similar results for all 3 groups (amputations, uninfected, and infected injuries). CONCLUSIONS: Our study shows that patients with infected and uninfected injuries surgically treated in Amman achieved similar outcomes. Despite late presentation, our patients had a comparable outcome to other studies dealing with early reconstruction. Reconstruction for the infected group required longer treatment time. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
