RESUMEN
The impact of infection on the prognosis of trauma patients according to severity remains unclear. We assessed the impact of infection complications on in-hospital mortality among patients with trauma according to severity. This retrospective cohort study used a nationwide registry of trauma patients. Patients aged ≥ 18 years with blunt or penetrating trauma who were admitted to intensive care units or general wards between 2004 and 2017 were included. We compared the baseline characteristics and outcomes between patients with and without infection and conducted a multivariable logistic regression analysis to investigate the impact of infection on in-hospital mortality according to trauma severity, which was classified as mild [Injury Severity Score (ISS) < 15], moderate (ISS 15-29), or severe (ISS ≥ 30). Among the 150,948 patients in this study, 10,338 (6.8%) developed infections. Patients with infection had greater in-hospital mortality than patients without infection [1085 (10.5%) vs. 2898 (2.1%), p < 0.01]. After adjusting for clinical characteristics, in-hospital mortality differed between trauma patients with and without infection according to trauma severity [17.1% (95% CI 15.2-18.9%) vs. 2.9% (95% CI 2.7-3.1%), p < 0.01, in patients with mild trauma; 14.8% (95% CI 13.3-16.3%) vs. 8.4% (95% CI 7.9-8.8%), p < 0.01, in patients with moderate trauma; and 13.5% (95% CI 11.2-15.7%) vs. 13.7% (95% CI 12.4-14.9%), p = 0.86, in patients with severe trauma]. In conclusion, the effect of infection complications in patients with trauma on in-hospital mortality differs by trauma severity.

RATIONALE: Necrotizing fasciitis (NF) is a rapidly progressing bacterial soft tissue infection with a high mortality rate. It is characterized by significant soft tissue destruction with associated sepsis. The mainstay of treatment is coverage with appropriate broad-spectrum antibiotic therapy and emergent surgical debridement. PATIENT CONCERNS: A previously healthy 66-year-old female presented with a deep laceration to her right, posterior calf with subsequent contamination with lake water. After the wound was irrigated and closed, the patient developed NF. DIAGNOSIS: Laceration of the right lower extremity complicated by NF secondary to Aeromonas sobria. INTERVENTIONS: The patient underwent emergent surgical debridements with intravenous broad-spectrum antibiotics and negative pressure wound therapy. The lower extremity was reconstructed with split-thickness skin grafts. OUTCOMES: The patient's initial penetrating trauma was closed in the emergency room, and the patient was discharged home with antibiotics. She returned the next day with unstable vitals and was admitted to the intensive care unit. Her condition continued to deteriorate, and she underwent serial surgical debridements. Her condition improved and was discharged home after 13âdays in the hospital. LESSONS LEARNED: Close monitoring for NF is important for tissue infections sustained in aquatic environments. Timely identification and surgical management of NF increases overall survival.

Tissue damage triggers a rapid and robust inflammatory response in order to clear and repair a wound. Remarkably, many of the cell biology features that underlie the ability of leukocytes to home in to sites of injury and to fight infection-most of which are topics of intensive current research-were originally observed in various weird and wonderful translucent organisms over a century ago by Elie Metchnikoff, the "father of innate immunity," who is credited with discovering phagocytes in 1882. In this review, we use Metchnikoff's seminal lectures as a starting point to discuss the tremendous variety of cell biology features that underpin the function of these multitasking immune cells. Some of these are shared by other cell types (including aspects of motility, membrane trafficking, cell division, and death), but others are more unique features of innate immune cells, enabling them to fulfill their specialized functions, such as encapsulation of invading pathogens, cell-cell fusion in response to foreign bodies, and their self-sacrifice as occurs during NETosis.

BACKGROUND: Traumatic injury can lead to a compromised intestinal epithelial barrier, decreased gut perfusion, and inflammation. While recent studies indicate that the gut microbiome (GM) is altered early following traumatic injury, the impact of GM changes on clinical outcomes remains unknown. Our objective of this follow-up study was to determine if the GM is associated with clinical outcomes in critically injured patients. METHODS: We conducted a prospective, observational study in adult patients (N = 67) sustaining severe injury admitted to a level I trauma center. Fecal specimens were collected on admission to the emergency department, and microbial DNA from all samples was analyzed using the Quantitative Insights Into Microbial Ecology pipeline and compared against the Greengenes database. α-Diversity and ß-diversity were estimated using the observed species metrics and analyzed with t tests and permutational analysis of variance for overall significance, with post hoc pairwise analyses. RESULTS: Our patient population consisted of 63% males with a mean age of 44 years. Seventy-eight percent of the patients suffered blunt trauma with 22% undergoing penetrating injuries. The mean body mass index was 26.9 kg/m. Significant differences in admission ß-diversity were noted by hospital length of stay, intensive care unit hospital length of stay, number of days on the ventilator, infections, and acute respiratory distress syndrome (p < 0.05). ß-Diversity on admission differed in patients who died compared with patients who lived (mean time to death, 8 days). There were also significantly less operational taxonomic units in samples from patients who died versus those who survived. A number of species were enriched in the GM of injured patients who died, which included some traditionally probiotic species such as Akkermansia muciniphilia, Oxalobacter formigenes, and Eubacterium biforme (p < 0.05). CONCLUSION: Gut microbiome diversity on admission in severely injured patients is predictive of a variety of clinically important outcomes. While our study does not address causality, the GM of trauma patients may provide valuable diagnostic and therapeutic targets for the care of injured patients. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Mycetoma is transmitted by thorns infected. The commonest site for mycetoma is the foot. The primary pulmonary are rare and usually secondary to other primary site. We report a case of pulmonary fungal mycetoma secondary to primary site in the knee. We do a review of the literature and we discuss the way of dissemination.
Le mycétome se transmet principalement par piqures d'épines d'arbustes infectés. Les localisations primitives au niveau du pied sont les plus fréquentes. Les localisations pulmonaires sont exceptionnelles et secondaires à des localisations périphériques primitives. Nous rapportons un cas de localisation pulmonaire d'un mycétome fongique secondaire à une localisation au niveau du genou, puis nous faisons une revue de la littérature et nous discutons de la voie de dissémination.

RATIONALE: Toothpick puncture (TPP) is a penetrating injury that can result in bringing pathogens to the deep space. Such penetrating wounds are typically of pinpoint size with initial symptoms appearing subtle. Consequently, the injury itself is often neglected by patients, or is not detected during physical examinations by medical doctors. Reported complications from such injuries include osteomyelitis and septic arthritis, mostly due to delayed treatment. PATIENT CONCERNS: A diabetic patient aged 83-year-old presented a 2-day history of skin redness, swelling, and tenderness over his forearm following a TPP a week earlier. Laboratory investigations showed leukocytosis with neutrophilic predominance and a high level of C-reactive protein. Before his operation, cultures of aspirated fluid from the injured site revealed the presence of Streptococcus anginosus, Streptococci viridans, Prevotella intermedia, and Pavimonas (Peptostreptococcus) micra. DIAGNOSIS: Intramuscular abscess associated with toothpick injury. INTERVENTIONS: Surgical irrigation with debridement and adjunctive antibiotics of ceftriaxone and clindamycin were given with a satisfactory response. Cultures of debrided tissue showed the presence of P intermedia and P (Peptostreptococcus) micra. OUTCOMES: A split-thickness skin graft was done. Patient was discharged on the 30th postoperative day. LESSONS: Toothpick injury, initial symptoms of which are subtle, can in some cases, lead to serious complications especially when managements are delayed. In such situations (including the present case), surgical irrigation and debridement are administrated for the eradication of infections, removal of potentially retained toothpick, and tissue cultures analyzed. Adjunctive antibiotics is recommended to combat both the aerobic and anaerobic microorganisms of the gastrointestinal tract, skin surface, and oral cavity.

This case report outlines the presentation and management of a young soldier who sustained a lower limb acacia thorn injury while on exercise in Kenya. The injury failed to heal with a subsequent ultrasound scan revealing a large retained thorn requiring surgical removal and wash out. From this case, lessons can be learnt regarding the management of thorn injuries, which are common in exercising troops in Kenya and indeed around the world. The key take-home messages are always consider a retained thorn if wounds fail to settle, use ultrasound as the imaging modality of choice, always remove identified retained thorns and if antibiotics are required use broad-spectrum antibiotics pending culture results.

INTRODUCTION: Mycobacterium smegmatis is a common microbe found in soil, dust, and water that rarely causes infections in humans. CASE REPORT: A 45-year-old man with a past medical history of hypertension presented with a nonhealing surgical wound in his anterior chest wall, measuring 0.5 cm x 0.5 cm x 0.3 cm with minimal serosanguinous drainage, that had been present for more than 1 year. Wound swab showed M smegmatis. He required a 3-month course of antibiotic treatment and advanced wound care that included packing the sinus wounds with silver-alginate dressings for the first 2 weeks followed by iodoform packing; once the infection and drainage had improved after 2 months of treatment, packing was changed to a collagen dressing. He responded well to treatment, and the ulcers completely closed at the end of his 3-month course. CONCLUSIONS: This case illustrates the importance of considering atypical microbial infections in the workup for chronic nonhealing wounds.

Osteomyelitis due to Ochrobactrum anthropi, a new genus Ochrobacterum widely distributed in the environment and occasionally associated with human infection, has been described in only a few case reports. We present a report of an unusual case of osteomyelitis caused by O. anthropi that was identified 9 years after a nail puncture to the lateral cuneiform bone. The patient was an 18-year-old male with a painful foot lesion that had originally been misdiagnosed as an osteolytic tumor. He underwent surgery and 2 firm pieces of rubber measuring 7 and 10 mm were removed from the lower portion of the lateral cuneiform bone, which appeared to be affected by an infection. After surgical debridement, O. anthropi was isolated from the bone cultures. The patient was successfully treated with a 6-week course of oral ciprofloxacin and clindamycin. At 1 year after the corrected diagnosis and appropriate treatment, he was symptom free and had resumed regular activities and an athletic lifestyle.

OBJECTIVE To determine the effects of 3 topically applied treatments (1% silver sulfadiazine cream [SSC], triple antimicrobial ointment [TAO], and hyperosmolar nanoemulsion [HNE]) on microbial counts, exuberant granulation tissue (EGT) development, and reepithelialization of contaminated wounds at the distal aspect of the limbs of horses. ANIMALS 8 healthy adult horses. PROCEDURES A 2.5 × 2.5-cm, full-thickness, cutaneous wound was created at the dorsal aspect of each metacarpus and metatarsus (1 wound/limb/horse), covered with nonadhesive dressing, and bandaged. Wounds were inoculated with bacteria and fungi the next day. Each wound on a given horse was randomly assigned to 1 of 4 treatment groups (SSC, TAO, HNE, or no topical treatment [control]). Bandage changes, culture of wound samples, treatments, photography for wound measurements, and biopsy were performed at predetermined time points. Time (days) until wound closure, number of EGT excisions, microbial counts, and scores for selected histologic characteristics were compared among groups. RESULTS Median time to wound closure for all groups was 42 days. Time to wound closure and histologic characteristics of wound healing did not differ among groups. Least squares mean microbial counts were significantly higher for HNE-treated wounds on days 9 and 21, compared with SSC-treated and TAO-treated wounds, but not controls. Proportions of SSC-treated (7/8) or HNE-treated (5/8) wounds needing EGT excision were significantly greater than that of TAO-treated (1/8) wounds. The proportion of SSC-treated wounds with EGT excision was greater than that of controls (3/8). CONCLUSIONS AND CLINICAL RELEVANCE None of the treatments resulted in more rapid wound closure, compared with that for untreated control wounds under the study conditions. When treatment is warranted, TAO may help to limit EGT formation.

PURPOSE: The tooth-knuckle injury (TKI) is a serious and potentially costly injury seen in orthopaedic practice. The aim was to conduct a systematic literature review on the factors associated with serious complications and high treatment costs in tooth-knuckle injuries. METHODS: MEDLINE, Scopus and CINAHL were used as the literature sources. INCLUSION CRITERIA: Original research papers that reported on factors predicting serious complications and high treatment costs in TKIs were included. There were no restrictions placed on study size, language, study design or date of publication. EXCLUSION CRITERIA: Case studies, case series and review articles were not included. RESULTS: After duplicates were removed, 403 unique studies remained; after titles and abstracts were screened, 48 titles remained and were retrieved in full text. Of these, 14 titles met the inclusion criteria and were included in the data synthesis. Tenosynovitis, septic arthritis, osteomyelitis and residual stiffness were common serious complications occurring in up to 36.3, 70.0, 47.6 and 65.3 % of cases, respectively. Amputation was also common in up to 18.0 % of injuries. Treatment costs were measured by length of hospital stay and the number of debridements required. On average, patients required 3.8-8 days of admission and 1.3-2.7 debridements each. CONCLUSION: Increased time delay from injury to treatment, deeply penetrating injuries, proximal interphalangeal joint (PIPJ) injuries and, possibly, E. corrodens infections were associated with serious complications in TKIs. Delayed treatment, inadequate treatment, PIPJ injuries and deeply penetrating injuries predicted higher treatment costs.

INTRODUCTION: Povidone Iodine (PVI) has been used to prevent wound infection for a long time, yet the merits and effectiveness of this agent in reducing the rates of infection in simple traumatic wounds have been debated. The aim of this study is determine the effect of PVI as skin disinfectant in preventing simple traumatic wound infection after repair in emergency departments. METHODS: This study is a single-blind, randomized, controlled trial, conducted at the emergency departments of two university hospitals. In this trial, those collecting and analyzing data were unaware of the assigned treatment. Participants included ED patients with simple traumatic wounds, randomly assigned to either experiment or control groups. Wounds were similarly irrigated with normal saline in both groups. But the skin around the wounds of patients in the experiment group was cleansed by PVI solution. The patients were followed till their next ED visit for stitch removal. The presence or absence of wound infection was considered as the primary outcome and assessed by an ED physician. RESULTS: In total, 444 patients were screened and included in the study. The patients were statistically similar according to their baseline characteristics. Men constituted 85% of the study participants. The highest numbers of reported wound sites belonged to head (30%), lower limbs (24%) and upper limbs (19%) accordingly. The rates of infections in the experiment and control groups were similar (p=0.231) but a significant association was observed between the rate of infections and wound location. Lower limbs (OR=9.23, p<0.0001) and upper limbs (OR=5.47, p=0.011) indicated the highest risks of wound infections among other locations. CONCLUSION: Our study showed that using PVI in the management of traumatic wounds did not reduced rate of infections.

INTRODUCTION: Mucormycosis is a rare but serious sequelae of penetrating trauma [1-5]. In spite of aggressive management, mortality remains high due to dissemination of infection. We completed a review of literature to determine the most optimal treatment of cutaneous mucormycosis which occurs secondary to penetrating trauma. METHODS: We completed a review regarding the management of mucormycosis in trauma patients. We selected a total of 36 reports, of which 18 were case-based, for review. RESULTS: Surgical debridement is a primary predictor of improved outcomes in the treatment of mucormycosis [3,6,7]. Anti-fungal therapy, especially lipid soluble formulation of Amphotericin B, is helpful as an adjunct or when surgical debridement has been maximally achieved. Further research is needed to fully evaluate the impact of topical dressings; negative pressure wound therapy is helpful. CONCLUSION: An aggressive and early surgical approach, even at the expense of disfigurement, is necessary to reduce mortality in the setting of cutaneous mucormycosis that results from penetrating trauma [4,8,9]. Anti-fungal therapy and negative pressure wound therapy are formidable adjuncts.

BACKGROUND: Survivors of combat trauma can have long and challenging recoveries, which may be complicated by infection. Invasive fungal infections are a rare but serious complication with limited treatment options. Currently, aggressive surgical debridement is the standard of care, with antifungal agents used adjunctively with uncertain efficacy. Anecdotal evidence suggests that antifungal agents may be ineffective in the absence of surgical debridement, and studies have yet to correlate antifungal concentrations in plasma and wounds. CASE PRESENTATION: Here we report the systemic pharmacokinetics and wound effluent antifungal concentrations of five wounds from two male patients, aged 28 and 30 years old who sustained combat-related blast injuries in southern Afghanistan, with proven or possible invasive fungal infection. Our data demonstrate that while voriconazole sufficiently penetrated the wound resulting in detectable effluent levels, free amphotericin B (unbound to plasma) was not present in wound effluent despite sufficient concentrations in circulating plasma. In addition, considerable between-patient and within-patient variability was observed in antifungal pharmacokinetic parameters. CONCLUSION: These data highlight the need for further studies evaluating wound penetration of commonly used antifungals and the role for therapeutic drug monitoring in providing optimal care for critically ill and injured war fighters.
