RESUMO
A hand represents 3% of the total body surface area. The hands are involved in close to 80% of all burns. The potential morbidity associated with hand burns can be substantial. Imagine a patient carrying a pan of flaming cooking oil to the doorway or someone lighting a room-sized pile of leaves and branches doused with gasoline. It is clear how the hands are at risk in these common scenarios. Not all burn injuries will require surgical intervention. Recognizing the need for surgery is paramount to achieving good functional outcomes for the burned hand. The gray area between second- and third-degree burns tests the skill and experience of every burn/hand surgeon. Skin anatomy and the size of injury dictate the surgical technique used to close the burn wound. In addition to meticulous surgical technique, preoperative and postoperative hand therapy for the burned hand is essential for a good functional outcome. Recognizing the burn depth is paramount to developing the appropriate treatment plan for any burn injury. This skill requires experience and practice. In this article, we present an approach to second- and third-degree hand burns.

Lower extremity amputee stump ulceration, irritation, and pain have been a deterrent to consistent long-term or continuous use of lower extremity prosthetics. This study is the first in a series that hypothesizes that these complications can be minimized through the insetting of a vascularized plantar free flap (VPFF) on the amputee stump. Using three hip disarticulated cadaver specimens, a VPFF was designed, dissected, and implanted on one transfemoral and two transtibial stumps. Using accepted vascular anastomosis techniques, the posterior tibial artery was anastomosed to the distal femoral or popliteal artery with corresponding anastomoses for venous drainage. In addition, the possibility of a limited to partial sensate flap may be created with a neurorrhaphy of the associated nerves. This potentially sensate area would provide plantar skin that aids the existing local sensate flap used to close the defect. It is hypothesized that this procedure offers significant rehabilitative and long-term benefits to battlefield or other acute causes for lower extremity amputation. The procedure can be accomplished in battlefield surgical setting as an immediate or delayed inset for some but not all traumatic amputations. Salvaging a partial or complete VPFF from a traumatized foot will obviously be predicated on the degree of trauma to the donor tissue.

INTRODUCTION: Hip fractures are one of the most common traumatic injuries in the United States, secondary to an aging population. Multiple comorbidities are found in patients who present to trauma centers (TCs) with isolated hip fractures (IHFs) including significant cardiac disease. Aortic stenosis (AS) among these patients has been recently shown to increase mortality. However, factors leading to death from AS are unknown. We hypothesize that pulmonary hypertension (PH) is a significant mechanism of death among IHF patients with AS. METHODS: This is a multicenter retrospective cohort study examining IHF patients treated at Level I and II TCs within a large hospital system from 2015 to 2019. Patients who had IHFs and AS were compared to those who had IHFs, AS, and PH. Multivariable logistic regression was used to risk adjust by age, race, insurance status, and comorbidities. The primary outcome was inpatient mortality. The secondary outcomes were hospital-acquired complications. RESULTS: A total of 1388 IHF patients with AS were included in the study. Eleven percent of these patients also had PH. The crude mortality rate was higher if IHF patients had both AS and PH compared to IHF with AS alone (9% vs 3.7%, P-value .003). After risk adjustment, a higher risk of mortality was still significant (aOR 2.56 [95% CI 1.28, 5.11]). In addition, IHF patients with both AS and PH had higher complication rates; the exposure group had higher percentage of pulmonary embolism (1.4% vs .2%, adjusted P-value .03), new-onset congestive heart failure (4.1% vs 1%, adjusted P-value .01), and sepsis/septicemia (3.5% vs 1.4%, adjusted P-value .05). CONCLUSION: In patients with IHFs, PH and AS increase the likelihood of inpatient mortality by 2.5 times compared to AS alone. Pulmonary hypertension among IHF patients with AS is an important risk factor to identify in the preoperative period. Early identification may lead to better perioperative management and counseling of patients at higher risk of complications.

OBJECTIVES: Mucormycosis is a rare angioinvasive infection caused by filamentous fungi with a high lethality among the immunocompromised. In healthy people, the innate immune system is sufficient to prevent infection. The exception to this is deep tissue exposure seen during trauma. The purpose of this study is to evaluate the epidemiology of mucormycosis using a statewide population-based data set. METHODS: This is a retrospective cohort study of all hospital admissions for mucormycosis within the state of Florida from 1997 through the beginning of 2020. A distribution map was created to evaluate for geographic variation. Botanical growth zones, based on plant hardiness, used by state environmental agencies and landscapers were also used to detect possible patterns based on climate conditions throughout Florida. A multivariable regression analysis was performed to account for confounders and limit bias. RESULTS: A total of 1190 patients were identified for mucormycosis infection. Only 86 of these patients were admitted for trauma. Cutaneous infections were more prevalent among trauma patients while non-trauma patients had more pulmonary infections (P = .04). Trauma patients with infection tended to be younger and less likely to suffer from comorbidities such as immunosuppression (36% vs 46%, P = .07) and diabetes (22.1% vs 47.1%, P ≤ .0001) as compared to their non-trauma counterparts. Mortality was similar with 17.8% for non-trauma patients and 15.1% for traumatized patients (AOR .80 [.42, 1.52]). Length of stay was longer for trauma patients (37.3 vs 23.0, P < .0001). Infections were less prominent in plant hardiness Zone 9 and Zone 10 as compared to Zone 8 (AOR .71 [.61, .82]; AOR .54 [.46, .64], respectively). CONCLUSION: Trauma patients who develop infection from mucormycosis are at high risk of death despite being a younger and healthier population. Mucormycosis infections were primarily soft tissue based among trauma patients. These infections are more prevalent in colder regions within Florida.

Fat embolism syndrome (FES) is a clinical entity occurring due to the presence of fat particles in the microcirculation, typically manifesting 12-72 hours after long bone trauma with respiratory distress, altered mental status, and petechial rash. Our case is that of a 17-year-old girl who suffered multiple orthopedic injuries without intracranial trauma after being a pedestrian struck by a vehicle. Despite presenting with a normal Glasgow Coma Score (GCS), within 4 hours of presentation, she was noted to have an acute mental status change to a GCS 7 with a normal computed tomography brain. Magnetic resonance imaging of the brain was suggestive of FES which, in this patient, had a rapidly progressing course with the development of severe cerebral edema and intracranial hypertension refractory to maximal medical therapy. Our patient required bilateral craniectomies for intracranial decompression and progressed over a 2-month hospital course to have subsequent cranioplasty and functional neurologic improvement. FES requires a high index of clinical suspicion in the presence of long bone fracture with unexplained altered mental status. The clinical course can be rapidly progressing with the development of intracranial hypertension which may benefit from surgical decompression with optimistic prognosis.

BACKGROUND: Infections within intensive care unit (ICU) are a persistent problem among the critically ill. Viral pneumonias have already been established as having a season variations. We attempt to evaluate the seasonal variations of pneumonia among the traumatically injured and the critically ill. MATERIALS AND METHODS: A retrospective cohort study among traumatized patients admitted from 1997 to 2017 to an ICU within the state of Florida was performed who were diagnosed with pneumonia. A multivariate regression analysis was performed to adjust for confounders. Time periods were divided into seasons: summer, winter, spring, and fall. A subset analysis of geriatric patients (>65 years) was also performed. RESULTS: A total of 869 553 patients were identified. The most common viral infection was influenza with adenovirus the least. The most common bacterial pneumonia was Staphylococcus aureus with Bordetella pertussis the least. Pneumonias had a seasonal variation. Compared to summer, winter had a higher likelihood of pneumonia overall (Adjusted Odds Ratio (AOR)1.13). This was seen in the spring (AOR 1.04) but not in fall (AOR 1.00). Viral infections were more pronounced (AOR 3.79) in all other seasons, while bacterial showed increased likelihood during winter (AOR 1.05). In geriatrics, pneumonia was again more likely in the winter (AOR 1.22) with both viral and bacterial infections being more pronounced during winter (AOR 4.79, AOR 1.09). DISCUSSION: Pneumonias are seen more frequently within the ICU during the winter for the traumatized patient. This held true with the critically ill geriatric population as well. This effect was observed in both viral and bacterial pneumonias.

Florida is among the nation's leaders in all-terrain vehicle (ATV)-related injuries and fatalities. We hypothesized that patients sustaining injuries while in compliance with ATV laws would demonstrate less severe injury patterns and improved outcomes when compared with noncompliant patients. We reviewed patients treated for ATV-related injuries over a 36-month period. We grouped patients according to conformity with Florida statutes and compared demographics, admission status, injuries sustained, and outcome measures. Three hundred seventy-seven patients were treated for ATV-related injuries. In 294 cases, sufficient data existed to assess compliance with Florida's statutes regarding ATV rider safety: safety helmet use for persons younger than age 16 years and prohibition of ATV operation on roadways. Forty-three per cent (n = 126) had violated one or both statutes; 57 per cent (n = 168) had violated neither. The group in violation was younger (15 vs 24 years, P < 0.001) and wore helmets less often (6 vs 34%, P < 0.001). Groups required admission at similar rates (62% violators vs 60% nonviolators, P = 0.770), showed similar injury patterns, and had comparable mortality rates (2% violators vs 5% nonviolators, P = 0.451). Current Florida laws are inadequate to prevent ATV-related injuries and their sequelae. This issue should be addressed through an increased focus on safety education for ATV operators.

INTRODUCTION: Hand injuries are common and costly. The need for hand surgery specialists is undeniable. In the state of Florida, the availability of specialty services in hand surgery is limited. Florida ranks 4th in population and 32nd in hand surgeons per 100,000 state residents. Recent media reports highlight these limitations among hand surgeons and other specialists in the state. METHODS: To evaluate the need for hand surgery centers of excellence in the state, we performed a retrospective review of data collected from the Agency for Health Care Administration database of hospital inpatient admissions from 1997 to the second quarter of 2007. Demographic information, details of the injury, and outcome data were evaluated in patients with amputation injuries. Amputations of the thumb, fingers, and hand/wrist/forearm were counted and factors associated with these injuries were recorded. Place of occurrence and injuries caused by machinery were evaluated. A regression analysis was performed to evaluate trends in the number of amputations and replantation procedures. RESULTS: We identified 4,858 patients with amputations in this time period. There were approximately 462 amputations per year. The trend in finger amputations appeared to be increasing yearly, whereas the trend for replantation surgery was decreasing. Six percent of the hospitals recording admissions with the Agency for Health Care Administration performed 68% of the replantation surgeries in the state. We also noted an increasing proportion of patients being admitted and treated outside of their own county and region. CONCLUSION: With fewer replantation surgeries performed and patients traveling farther for treatment we conclude that there is a need for coordinated evaluation, triage and treatment of patients with hand injuries requiring specialized hand surgery services at centers of excellence in Florida.

Background: Merkel cell carcinoma (MCC) is a relatively rare and aggressive cutaneous neuroendocrine malignancy characterized by high incidence of local recurrence, distant metastases, regional nodal metastases, and high mortality. Clinically, MCC presents as a persistent asymptomatic red/pink shaped nodule, usually smaller than 2 cm with nontender intracutaneous swelling, with rapidly growing localized disease with lymph node metastases preceding distant metastases. Because of its rare nature and the lack of comprehensive understanding of the disease, management of MCC has been controversial. Methods: An 87-year-old retired Caucasian male with a history of tobacco use, chronic sun exposure, and multiple squamous and basal cell carcinomas presented with a 1.8 × 1.3 cm red, nontender nodule on the dorsum of the proximal phalanx of the left long finger first noticed 6 months prior to presentation. Biopsy was consistent with MCC after which he was treated with wide local excision, full-thickness skin grafting, and sentinel lymphadenectomy (1/4 nodes positive) followed by adjuvant radiation therapy. Results: He recovered appropriately and was clinically and radiographically disease free at 2.5-year follow-up. Conclusion: Although it remains rare, MCC has increased in incidence over the last several decades and has a predilection to occur over sun exposed areas. Highly aggressive, it has a high incidence of regional and distant metastasis as well as local recurrence. As a result, it is important that practitioners involved in the care of skin and hand lesions be aware of this condition and the need for a multidisciplinary treatment approach.

BACKGROUND: Thermally injured patients are at high risk for infections, including hospital acquired infections (HAIs). We modeled a twice-daily chlorhexidine gluconate (CHG) bath protocol aimed at decreasing HAIs. METHODS: Bathing with a 0.9% CHG solution in sterile water was provided twice daily as part of routine care. Institutional HAI prevention bundles were in place and did not change during the study. Baseline HAI rates were collected for 12 months before the quality study implementation. Centers for Disease Control and Prevention definitions for HAIs were used; our blinded Infection Control physician made each determination. This was an Institutional Review Board-exempt protocol. RESULTS: The study cohort included 203 patients before the quality trial and 277 patients after the quality trial. The median burn area was 25% of total body surface area. Baseline HAI rates were as follows: ventilator-associated pneumonia, 2.2 cases/1,000 ventilator-days; cathether-associated urinary tract infection, 2.7 cases/1,000 catheter-days; central line-associated bloodstream infection, 1.4 cases/1,000 device-days. With implementation of this protocol, the rates dropped to zero and have stayed at that level with the exception of 1 cathether-associated urinary tract infection. There were no untoward effects or observed delays in wound healing with this protocol. All of these changes were clinically significant, although not statistically significant; the study was not powered for statistical significance. CONCLUSIONS: Using this nurse-driven protocol, we decreased, in a sustainable manner, the HAI rate in our intensive care unit to zero. No integumentary difficulties or wound healing delays were related to this protocol.

BACKGROUND: Census predictions for Florida suggest a 3-fold increase in the 65 and older population within 20 years. We predict resource utilization for burn patients in this age group. METHODS: Using the Florida Agency for Healthcare Administration admission dataset, we evaluated the effect of age on length of stay, hospital charges, and discharge disposition while adjusting for clinical and demographic factors. Using US Census Bureau data and burn incidence rates from this dataset, we estimated future resource use. RESULTS: Elderly patients were discharged to home less often and were discharged to short-term general hospitals, intermediate-care facilities, and skilled nursing facilities more often than the other age groups (P < .05). They also required home health care and intravenous medications significantly more often (P < .05). Their length of stay was longer, and total hospital charges were greater (P < .05) after adjusting for sex, race, Charleson comorbidity index, payer, total body surface area burned, and burn center treatment. CONCLUSIONS: Our data show an age-dependent increase in the use of posthospitalization resources, the length of stay, and the total charges for elderly burn patients.

BACKGROUND: Bacillus cereus has been increasingly recognized as a virulent pathogen, particularly in immunocompromised patients. METHODS: Presented is a case report of a 24-year-old man with end-stage liver disease secondary to primary sclerosing cholangitis, who developed necrotizing fasciitis of the right lower leg due to B. cereus. The bacterium isolated from the patient was compared with environmental strains for quantity of secreted proteins as well as hemolytic and cytotoxic activities. RESULT: Despite above-the-knee amputation and aggressive antibiotic therapy, the patient expired on hospital day 13. The patient isolate demonstrated a protein secretion pattern and cytotoxicity similar to those of an environmental strain known to produce exotoxins. However, the isolate did produce a larger ratio of zone of hemolysis to colony size on blood agar plates compared with the environmental strain. CONCLUSION: To the best of our knowledge, this is the only report of B. cereus as the etiology of necrotizing fasciitis in a patient with end-stage liver disease. Because the infecting bacterium correlates with the environmental strain, the severity of the patient's disease is likely related to his immunocompromised state. Therefore, B. cereus should be considered a potential pathogen rather than a contaminant.

This presentation represents a unique anatomic predisposition to the development of hypothenar hammer syndrome (HHS). In this case, a communicating branch of the ulnar nerve to the median common digital nerve of the ring finger was identified crossing volar to the superficial palmar arch. This relationship caused thrombosis of the superficial palmar arch proximal to this crossing nerve branch. The aberrant course of this nerve created a structural anomaly contributing to HHS, which ultimately mandated surgical intervention.

A case is discussed in which a young male was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits when he was an infant. This initial surgical procedure was later followed by webspace deepening and ultimately by distraction lengthening of the digits. At 8 years of age, he has a very functional hand with mobile metacarpophalangeal joints in all reconstructed fingers. In fact, he uses this reconstructed right hand as his dominant extremity. The case is discussed in context of phalangeal growth potential, specific indications for this type of reconstruction, and final long-term outcome. This case also helps to recommend rational treatment protocols for similar congenital hand anomalies.
