A personalized approach to modify axillary crutches using 3D printing technology.

3D printers can produce specific medical objects that are tailored to the individual patient's needs, and if they are combined with a personalized orthopedic rehabilitation, it can result in improved functional outcomes. We present a 26-year-old male war victim with multiple injuries in his lower and upper limbs. The use of standard crutches was impossible, so we developed a customized 3D-printed crutch with a relative low cost. The gait and balance scores-as a part of the Tinetti score-improved immediately, and the patient's QUEST 2.0 questionnaire was high after 4 weeks of the crutches use, indicating high patient's satisfaction.

AI-based mobile application to fight antibiotic resistance.

Antimicrobial resistance is a major global health threat and its development is promoted by antibiotic misuse. While disk diffusion antibiotic susceptibility testing (AST, also called antibiogram) is broadly used to test for antibiotic resistance in bacterial infections, it faces strong criticism because of inter-operator variability and the complexity of interpretative reading. Automatic reading systems address these issues, but are not always adapted or available to resource-limited settings. We present an artificial intelligence (AI)-based, offline smartphone application for antibiogram analysis. The application captures images with the phone's camera, and the user is guided throughout the analysis on the same device by a user-friendly graphical interface. An embedded expert system validates the coherence of the antibiogram data and provides interpreted results. The fully automatic measurement procedure of our application's reading system achieves an overall agreement of 90% on susceptibility categorization against a hospital-standard automatic system and 98% against manual measurement (gold standard), with reduced inter-operator variability. The application's performance showed that the automatic reading of antibiotic resistance testing is entirely feasible on a smartphone. Moreover our application is suited for resource-limited settings, and therefore has the potential to significantly increase patients' access to AST worldwide.

Decision-making algorithm for sequential treatment of diaphyseal bone gaps in war-wounded patients in the Middle East.

INTRODUCTION: Tibial bone gaps after war injuries are common and can be managed by different types of surgery, including compression, bone graft, tibialisation of fibula, bone transport, and free flaps. Here, we present an algorithm developed at a humanitarian surgical hospital to manage tibial bone gaps. We also identify some key factors affecting patient outcomes and describe some clinical considerations for choosing treatment strategy. METHOD: We performed retrospective data analysis on war-wounded adult patients with tibial injuries treated at our project according to the described algorithm. Patient outcomes were followed for at least four  years. Outcomes assessed were length of stay, complication rate, re-admission (late complications), and final discharge. RESULTS: Among the 200 included patients, 103 (51.5%) had bone gaps. Univariate analysis showed that the presence of a bone gap, but not its size, was associated with significantly increased risk of early complications, while type of surgery was significantly correlated with re-admission. Presence of a bone gap and type of surgery were each significantly associated with length of stay. Bone gap size showed no correlation with outcomes, an unexpected finding. DISCUSSION: Soft tissue damage with compromised vascularity may explain the lack of association between bone gap size and outcomes. Specialised centres using standardised approaches to complex surgical reconstruction can play an important role in expanding the evidence base needed to improve case management. CONCLUSIONS: Less invasive procedures may lead to better patient outcomes, although unfortunately may not always be possible given the nature of the injury and/or injury site.

Post-traumatic osteomyelitis in Middle East war-wounded civilians: resistance to first-line antibiotics in selected bacteria over the decade 2006-2016.

BACKGROUND: War-wounded civilians in Middle East countries are at risk of post-traumatic osteomyelitis (PTO). We aimed to describe and compare the bacterial etiology and proportion of first-line antibiotics resistant bacteria (FLAR) among PTO cases in civilians from Syria, Iraq and Yemen admitted to the reconstructive surgical program of Médecins Sans Frontières (MSF) in Amman, Jordan, and to identify risk factors for developing PTO with FLAR bacteria. METHODS: We retrospectively analyzed the laboratory database of the MSF program. Inclusion criteria were: patients from Iraq, Yemen or Syria, admitted to the Amman MSF program between October 2006 and December 2016, with at least one bone biopsy sample culture result. Only bone samples taken during first orthopedic surgery were included in the analysis. To assess factors associated with FLAR infection, logistic regression was used to estimate odds ratio (ORs) and 95% confidence intervals (CI). RESULTS: 558 (76.7%) among 727 patients included had ≥1 positive culture results. 318 were from Iraq, 140 from Syria and 100 from Yemen. Median time since injury was 19 months [IQR 8-40]. Among the 732 different bacterial isolates, we identified 228 Enterobacteriaceae (31.5%), 193 Staphylococcus aureus (26.3%), 99 Pseudomonas aeruginosa (13.5%), and 21 Acinetobacter baumanii (2.8%). Three hundred and sixty four isolates were FLAR: 86.2% of Enterobacteriaceae, 53.4% of Pseudomonas aeruginosa, 60.5% of S. aureus and 45% of Acinetobacter baumannii. There was no difference in bacterial etiology or proportion of FLAR according to the country of origin. In multivariate analysis, a FLAR infection was associated with an infection of the lower extremity, with a time since the injury ≤12 months compared with time > 30 months and with more than 3 previous surgeries. CONCLUSIONS: Enterobacteriaceae were frequently involved in PTO in war wounded civilians from Iraq, Yemen and Syria between 2006 and 2016. Proportion of FLAR was high, particularly among Enterobacteriaceae, regardless of country of origin.

Bone cultures from war-wounded civilians in the Middle East: a surgical prospective.

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.

Introducing an antibiotic stewardship program in a humanitarian surgical hospital.

Antibiotic stewardship program (ASP) implementation in humanitarian settings is a new endeavor. Doctors Without Borders/Médecins Sans Frontières introduced an ASP within a hospital in Amman, Jordan, where patients from Iraq, Syria, and Yemen with chronic, often multidrug-resistant, infections related to war are managed. Antibiotics were reviewed, and real-time recommendations were made to optimize choice, dose, duration, and route by a small team. Over the first year of implementation, acceptance of the ASP's recommendations improved. When compared with the year prior to implementation, antibiotic cost in 2014 declined considerably from approximately $252,077 (average, $21,006/month) to <$159,948 ($13,329/month), and a reduction in use of broad-spectrum agents was observed. An ASP in a humanitarian surgical hospital proved acceptable and effective, reducing antibiotic expenditures and use of broad-spectrum agents.

The short musculoskeletal functional assessment (SMFA) score amongst surgical patients with reconstructive lower limb injuries in war wounded civilians.

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.

Multidrug-resistant chronic osteomyelitis complicating war injury in Iraqi civilians.

BACKGROUND: War-related orthopedic injury is frequently complicated by environmental contamination and delays in management, placing victims at increased risk for long-term infectious complications. We describe, among Iraqi civilians with war-related chronic osteomyelitis, the bacteriology of infection at the time of admission. METHODS: In the Médecins Sans Frontières Reconstructive Surgery Project in Amman, Jordan, we retrospectively reviewed baseline demographics and results of initial intraoperative surgical cultures among Iraqi civilians with suspected osteomyelitis. RESULTS: One hundred thirty-seven patients (90% male; median age, 35 years [interquartile range {IQR}, 28-46]; median time since initial injury, 19 months [IQR, 10-35]) were admitted with suspected chronic osteomyelitis after war-related injury. One hundred seven patients had a positive intraoperative culture. Before arrival, patients had undergone a median of 4 (IQR, 2-6) surgical procedures in Iraq. Fifty-nine (55%) of 107 patients with confirmed osteomyelitis had a multidrug-resistant (MDR) organism isolated at admission: cefepime-resistant Enterobacteriaceae (n = 40), methicillin-resistant Staphylococcus aureus (n = 16), and MDR Acinetobacter baumannii (n = 3). An association of borderline significance existed between a history of more than two prior surgical procedures in Iraq and an MDR isolate at program entry (multivariate: odds ratio, 5.3; 95% confidence interval, 0.9-30.6; p = 0.064). CONCLUSION: Health care actors, including Iraqi health facilities and humanitarian medical organizations, must be aware of the link between chronic war injury and antimicrobial drug resistance in this region and should be prepared for the management challenges involved with the treatment of chronic drug-resistant osteomyelitis.
