RESUMEN

BACKGROUND: Survivors from Ebola virus disease (EVD) may be at the origin of EVD resurgence. METHODS: Simultaneous reactivity to at least 2 Ebola virus or Zaire ebolavirus (EBOV) antigens was detected in 11 of 488 (2.3%; 95% confidence interval [CI], 1.1-4.0) suspected EVD patients who were discharged as negative after 2 consecutive negative tests during the 10th Ebola outbreak in the Democratic Republic of the Congo. RESULTS: After extrapolating the total number of individuals discharged as negative during the entire outbreak, we estimated a total of 1314 additional missed Ebola cases. CONCLUSIONS: These findings emphasize the usefulness of an EBOV serology analysis and the importance of extending epidemic surveillance to clinically suspected cases who were discharged as negative.

RESUMEN

PURPOSE: Acetabular fractures are frequently associated with other skeletal injuries, particularly knee injuries. This study aims to evaluate the relationship between posterior acetabular fractures and knee injury, analyzing its patterns and association with other injuries. METHODS: This is a retrospective monocentric study in a tertiary referral centre. We reviewed the data (age, sex, type of fracture, and concomitant injury) of patients hospitalized for a posterior acetabular fracture. We recorded concomitant knee injury diagnosed up to one year following acetabular fracture. RESULTS: Two-hundred-seventeen patients (177 males/40 females) were included. The mean age was 40.5 years. Eighty-five patients (39%) had a concomitant hip dislocation, nine (4.1%) had sciatic nerve palsy, 17 (7.8%) had upper extremity injury, and 18 (8.3%) had lower extremity injury (other than the knee). Eight (3.7%) patients had spine injury, 11 (5.1%) had severe thoracic injury, nine (4.1%) had an abdominal injury, and four (1.8%) had a head injury. There were 33 (15.21%, 95% CI 10.80-20.8%) patients (30 M/3 F) (group 1) with a concomitant knee injury and 184 patients without a concomitant knee injury(group 2). The mean age in group 1 was 34.3 compared to 45.4 in group 2(p = 0.021). The pattern analysis revealed five fractures, 14 ligamentous injuries (PCL injuries = 68%), and 14 soft tissue injuries. Sixteen (48.48%) injuries were identified during hospitalization and 17 (51.51%) during follow-up. There were an association between knee injury and upper extremity injury (OR = 3.49 95% CI 1.12-10.00,p = 0.022) and other lower extremity injury (OR = 3.18 95% CI 1.03-8.95,p = 0.032). DISCUSSION: Knee injury is the second most frequent lesion associated with posterior acetabular fractures. Being missed in half of cases, we recommend a systematic examination of ipsilateral knees under general anaesthesia, keeping a high index of suspicion and a low threshold for complementary knee imaging. Knee injury should be mainly looked for in patients younger than 60 years and in those with upper and/or lower extremities injuries.

RESUMEN

PURPOSE: Hidden infections in a reconstructive surgery program are frequently underestimated. METHODS: A retrospective study was undertaken of 1,891 civilian war-wounded patients from Iraq, Syria, Yemen and Gaza treated in Amman from August 2006 to January 2016. One thousand three hundred and fifty-three underwent surgical interventions for previous bone injury and had systematic bone cultures. RESULTS: Among patients (167) without any clinical, biological or radiological signs of infection, 46% demonstrated infection based on bone cultures. We conclude that bone culture should become a prerequisite for any reconstruction in such contexts.

RESUMEN

A huge change is needed in the conception and implementation of surgical care during sudden-onset disasters (SOD). The inadequate surgical response mounted by the majority of foreign medical teams (FMT) after Haiti's earthquake is a striking example of the need for a structured professional approach. Logistical capacity already exists to provide safe, timely, effective, efficient, equitable and ethical patient-centred care with minimum standards. However, knowledge, skills and training in the fields of general, orthopaedic and plastic surgery need further clarification. Surgical activity data and clinical examples from several Médecins Sans Frontières-France (MSF) projects are used here to describe the skill set and experience essential for surgeons working in SOD contexts.

RESUMEN

BACKGROUND: As part of its policy to shift monitoring of antiretroviral therapy (ART) to primary health care (PHC) workers, the Ministry of Health of the Democratic Republic of Congo (DRC) tested the feasibility of using dried blood spots (DBS) for viral load (VL) quantification and genotypic drug resistance testing in off-site high-throughput laboratories. METHODS: DBS samples from adults on ART were collected in 13 decentralized PHC facilities in the Nord-Kivu province and shipped during program quarterly supervision to a reference laboratory 2000 km away, where VL was quantified with a commercial assay (m2000rt, Abbott). A second DBS was sent to a World Health Organization (WHO)-accredited laboratory for repeat VL quantification on a subset of samples with a generic assay (Biocentric) and genotypic drug resistance testing when VL >1000 copies per milliliter. FINDINGS: Constraints arose because of an interruption in national laboratory funding rather than to technical or logistic problems. All samples were assessed by both VL assays to allow ART adjustment. Median DBS turnaround time was 37 days (interquartile range: 9-59). Assays performed unequally with DBS, impacting clinical decisions, quality assurance, and overall cost-effectiveness. Based on m2000rt or generic assay, 31.3% of patients were on virological failure (VF) and 14.8% presented resistance mutations versus 50.3% and 15.4%, respectively. CONCLUSION: This study confirms that current technologies involving DBS make virological monitoring of ART possible at PHC level, including in challenging environments, provided organizational issues are addressed. Adequate core funding of HIV laboratories and adapted choice of VL assays require urgent attention to control resistance to ART as coverage expands.

RESUMEN

PURPOSE: Carrying out osteosynthesis is challenging, and controlling for results and complications is necessary to define the limits of acceptable complications. Within the context of sudden-onset disasters, comparing internal with external osteosynthesis remains controversial. METHODS: The most recent and significant Médecins Sans Frontières (MSF) experience with osteosynthesis was following the earthquake in Haiti in 2010: 353 external fixators were used in the 12 months following the catastrophe, 62 of which were used in the first month. Carrying out internal osteosynthesis was possible two weeks following the earthquake. RESULTS: The most common indication for open tibial fracture was Gustillo grade 2 or 3. Conversion rate from external to internal osteosynthesis remains anecdotal for several practical reasons. Advantages and drawbacks of external fixators are discussed in the context of precarious situations frequently encountered by MSF. CONCLUSIONS: External osteosynthesis as a primary and definitive treatment for open fractures, especially of the leg, remains the most frequently used and best-adapted procedure in the context of sudden-onset disasters, even though not ideal.

RESUMEN

Establishing triage is necessary in mass casualty events. If the concept of triage itself is easy, its application in the field encounters many difficulties at times unforseen. MSF offers a list of the main obstacles encountered when establishing an efficient triage system.

RESUMEN

PURPOSE: The decision to amputate is always difficult but becomes even harder in emergency situations, which usually present extra complicating factors. MSF EXPERIENCE: These include human factors (related to both the surgeon and the patient); poor or nonexistent medical facilities, especially in war conditions or resource-poor countries; and cultural and religious considerations. Médecins Sans Frontières (MSF) has developed a quick medical and logistical response that relies on surgical protocols adapted to emergency situations, together with complete "kits" of medical equipment, supplies and inflatable facilities. CONCLUSION: Our response to Haiti's 2010 earthquake relied on these tools but also highlighted the need to develop more detailed protocols that will help our teams on the ground.

RESUMEN

BACKGROUND: We studied virological outcome and drug resistance in patients on antiretroviral therapy (ART) in health care centers in the Democratic Republic of Congo and looked for the presence of drug resistance in antiretroviral-naive patients attending the same clinics. METHODS: In 2008, we conducted a cross-sectional survey among patients on ART for ≥ 12 months in 4 major cities [Kinshasa (n = 289), Matadi (n = 198), Lubumbashi (n = 77), and Mbuji-Mayi (n = 103)]. Genotypic drug resistance tests were done with an in-house assay on samples with viral load >1000 copies/mL. ART-naive patients (n = 283) were also consecutively enrolled in the same clinics. RESULTS: Of the 667 patients on ART, >98% received Lamivudine + Stavudine/azidothymidine + Nevirapine/Efavirenz as first-line regimen and 74.4% were women. Median time on ART was 25 months [interquartile ratio (IQR), 19-32] in Kinshasa, 26 months (IQR, 19-32) in Matadi, 27 months (IQR, 19-44) in Lubumbashi, and 19 months (IQR, 16-24) in Mbuji-Mayi. A total of 97 patients (14.6%) had viral load >1000 copies/mL, and among the 93 successfully sequenced samples, 78 (83.9%) were resistant to at least 1 drug of their ART regimen: 68 harbored resistance mutations to nucleoside reverse transcriptase inhibitor (NRTI) and nonnucleoside reverse transcriptase inhibitor (NNRTI), 2 to NRTI only, 7 to NNRTI only, and 1 to NRTI + NNRTI + protease inhibitor. The majority of patients, 70/78 (89.7%), were resistant to at least 2 of the 3 drugs from their treatment. The use of next-generation NNRTI, etravirine was already compromised for 19.2% (15/78) of the patients and 7 patients had the K65R mutation compromising the use of tenofovir in second-line regimens. The proportion of antiretroviral-resistant patients increased over time from 8.4% to 18.6% for patients on ART for 12-23 months or >35 months (P = 0.013), respectively. Virological failure and rates of drug resistance were significantly higher among men than women, 19.9% versus 8.8%, respectively (P = 0.0001). Among the 253 recently diagnosed patients, 20 (7.9%) harbored resistance mutations. CONCLUSIONS: The accumulation of drug resistance mutations with time on ART needs further attention, and surveillance should be reinforced in ART programs in sub-Saharan Africa.

RESUMEN

OBJECTIVES: Dried blood spots (DBS) and dried plasma spots (DPS) are easy to collect and store, and have been successfully tested as an alternative to plasma for performing virological analyses. Adequate storage conditions still need to be established and cell-associated proviral DNA in DBS can contribute to the amplified products. We evaluated these two parameters. METHODS: Residual samples from 34 HIV-1-infected patients [mean viral load (VL) = 3.93 log(10) copies/mL] were used to prepare DPS and DBS, then stored at 20 degrees C and 37 degrees C. HIV-1 nucleic acids were extracted, with or without DNase treatments, to perform HIV-1 VL quantification and nested RT-PCR to amplify the reverse transcriptase gene (798 bp). RESULTS: For DBS stored for 3 months at 20 degrees C, VL could be measured for all samples and results were comparable to plasma VL. At 37 degrees C, a slight decrease was observed after 2 and 3 months (0.16 and 0.37 log(10) copies/mL mean difference, respectively). For DPS, a significant decrease in VL (0.70 and 1.07 log(10) copies/mL after 1 and 2 months, respectively) was seen at 37 degrees C, but not at 20 degrees C. PCR amplifications from DPS were only successful for 50% of samples with an initial VL >10 000 copies/mL after 1 month at 20 degrees C. From DBS, PCR amplifications are possible until 3 months for samples with plasma VL >5000 copies/mL. VL and PCR results for DBS treated with DNase are close to results obtained for DPS. CONCLUSIONS: Virological monitoring is still feasible for DBS after 3 months of storage at 37 degrees C when VL is >5000 copies/mL, but DNA contributes largely to the final results.

RESUMEN

OBJECTIVES: Health care delivery is particularly problematic in fragile states often connected with increased incidence of communicable diseases, among them tuberculosis. This article draws upon experiences in tuberculosis control in four fragile states from which four lessons learned were derived. METHODS: A structured inventory to extract common themes specific for TB control in fragile states was conducted among twelve providers of technical assistance who have worked in fragile states. The themes were applied to the TB control programs of Afghanistan, DR Congo, Haiti and Somalia during the years 2000-2006. RESULTS: Case notifications and treatment outcomes have increased in all four countries since 2003 (treatment success rates 81-90%). Access to care and case detection however have remained insufficient (case detection rates 39-62%); There are four lessons learned: 1. TB control programs can function in fragile states. 2. National program leadership and stewardship are essential for quality and sustained TB control. 3. Partnerships with non-governmental providers are vital for continuous service delivery; 4. TB control programs in fragile states require consistent donor support. CONCLUSION: Despite challenges in management, coordination, security, logistics and funding, TB control programs can function in fragile states, but face considerable problems in access to diagnosis and treatment and therefore case detection.

RESUMEN

This operational research conducted among TB patients co-infected with HIV in North Kivu had three objectives: (i) to clarify the local perception of a certain type of pain (michi in the local language) in patients on antiretroviral treatment (ART); (ii) to identify the attitudes of health care personnel regarding the management of ART side effects; and (iii) to explore ways to improve the quality of life of patients on ART and provide them with pain relief. Twenty in-depth interviews were conducted with patients on ART and their medical care providers in district health centers of North-Kivu and at patients' homes. A semantic analysis of the term michi revealed a nosologic folk entity based on a naturalistic view of the body; the term michi is used to name: (i) the "roots" of plants or trees; (ii) channels (veins, arteries, but also nerves and tendons) in the body through which fluids (blood, water) and energy are conveyed; (iii) different types of acute pain, possibly located along these channels. The description (location, duration, and intensity) of the functional signs and the context of their occurrence (while taking Stavudine) confirmed the medical diagnosis of acute sensory neuropathies. Although a classic ART side effect, neuropathies are underdiagnosed by health workers who find it difficult to recognize signs of treatment toxicity in apparently trivial symptoms. Different reasons account for this: (i) healthcare staff have little time to spend with TB/HIV patients and thus provide inadequate management of functional symptoms; (ii) insufficient attention is paid to patients' acute pain, which is often perceived as "normal"; (iii) insufficient knowledge of ART side effects due to staff turnover higher than the frequency of training that programmes. The study was conducted as part of the DR Congo national programmes for TB and AIDS and led to the formulation of recommendations about improving, especially through training, the assessment of functional symptoms as expressed in the main cultural areas of the country, including increased awareness of their vernacular expressions. This study also stressed the need for early diagnosis and management of iatrogenic neuropathy. The integration of leprosy and TB programmes in DR Congo in principle offers a suitable framework to develop synergies for the management of peripheral neuropathy. Finally, providing increased attention to patients (empathy, listening and counselling) requires time and calls for a careful analysis of the care providers' workload, to facilitate the smooth integration of HIV care into general health services.

RESUMEN

The development and validation of dried sample spots as a method of specimen collection are urgently needed in developing countries for monitoring of human immunodeficiency virus (HIV) infection. Our aim was to test some crucial steps in the use of dried spots, i.e., viral recovery and storage over time. Moreover, we investigated whether dried plasma and blood spots (DPS and DBS, respectively) give comparable viral load (VL) results. Four manual RNA extraction methods from commercial HIV type 1 (HIV-1) VL assays--a QIAamp minikit (Qiagen), the Abbott Molecular sample preparation system, the Nuclisens assay (bioMarieux), and High Pure viral nucleic acid kit (Roche Applied Science)--were compared for VL quantification and PCR amplification for genotypic drug resistance testing on dried spots from spiked plasma and residual samples from HIV-1 patients (n = 47; median VL, 4.13 log(10) copies/ml). RNA recovery from DPS was efficient using Nuclisens extraction (median difference, 0.03 log(10) copies/ml) and slightly underestimated using the Abbott Molecular sample preparation system (median difference, 0.35 log(10) copies/ml). PCR amplification results were in concordance. Measurements from DBS overestimated VL for plasma, with VL results showing <3.7 log(10) copies/ml. VL was stable for up to 3 months in spiked DPS stored at 20 degrees C but for only 1 month at 37 degrees C. A faster decline was observed in PCR efficiency: DPS could be stored for 1 week at 37 degrees C and for 1 month at 20 degrees C. In conclusion, the RNA extraction method is an important factor in obtaining reliable RNA quantification and PCR amplification of HIV-1 on DPS/DBS. DBS could be used as an alternative for DPS depending on HIV RNA cutoffs for virological failure. VL measurements remain stable over a longer period than do PCR amplification results.
