Necrotizing fasciitis (NF) is a severe soft tissue infection caused by bacterial fascia invasion and quick spreading to the muscle and subcutaneous tissues. Treatments of NF should be conducted by extensive debridement and antibiotic therapies. This report presented a 53-year-old woman with diabetes mellitus (DM) and hypothyroid who was referred to our medical center with lower limb pain and significant swelling after mild trauma. The patient was diagnosed with NF due to E. coli. She underwent surgical interventions for debridement and long-term antibiotic therapy. The patient recovered successfully without complications or range of motion (ROM) restriction in the hip and knee. It is recommended that immediate actions be taken in NF cases to preserve the remaining tissues and provide better outcomes.

Background: Clostridium species are known to be the primary causative organism of gas gangrene. Non-clostridial gas gangrene (NCGG) is another rare necrotizing entity often associated with an underlying disease, particularly diabetes mellitus, and has a high mortality rate.

Case report: A 16-year-old, immunocompetent male was referred to us after four days, following a roadside accident, with a degloving injury over the thigh and knee along with fractures around the knee. Although clinico-radiologically suspicious of gas gangrene, the initial smear report was negative for any Gram-positive bacilli. On the same day, he underwent aggressive debridement with an external fixator spanning the knee to salvage the limb. On post-operative day one, due to deteriorating general clinical condition and a strong clinical suspicion of gas gangrene, he underwent above-knee amputation (open stump) after discussion with microbiologists and physicians.

Results: Polymicrobial non-clostridial infection was seen in culture reports taken serially at different stages of management. The latest follow-up showed a healed amputation stump following split skin grafting.

Conclusion: Although rare, polymicrobial infections can present as non-clostridial gas gangrene even in an immunocompetent patient. A high index of clinical suspicion with a multi-disciplinary approach helps in early decision-making to avoid a devastating outcome.

Background: There are no comprehensive and accurate statistics on epidemiology and clinical features, especially during the COVID-19 period. The present study tries to describe the pediatric traumas in a referral treatment center in northern Iran during the COVID-19 period and to compare the available statistics with the years before pandemics to examine the differences in the epidemiology of this event in our country.

Methods: This cross-sectional study was performed on 543 children under 15 years admitted to this hospital due to different types of traumas in the first six months of 2019 (before the COVID-19 pandemic) and the first six months of 2020 (coinciding with the peak of the pandemic). The information was retrospectively collected by reviewing the hospital recorded files and the trauma-specific hospital information system.

Results: In total, 436 children were referred before the COVID-19 pandemic period and 107 within the pandemic outbreak. The peak age of patients admitted was 2 to 6 years (32.0%) and 70.5% were male. Most of the pointed children had normal weight. The most common mechanism of trauma before and during the COVID-19 pandemic was falling from a height (46.3% versus 42.1%), followed by road accidents (35.6% versus 36.4%). The overall prevalence of penetrating trauma was 6.9% and 9.3%. The most common body sites affected were the head and neck (32.1%) followed by extremities (before the COVID-19 period) and extremities (29.0%) followed by the head and neck (24.3%) (in the COVID-19 period). The overall rates of multiple trauma before and within the pandemic were also 35.6% versus 35.5%. In children aged 12 to 15 years, road accidents were more reported during the COVID-19 pandemic period (68.4% versus 50.9%) and contrarily falling from a height more before the pandemic (25.5% versus 0.0%). In children under two years of age, head and neck trauma was more reported before the COVID-19 period than in the COVID-19 period (55.6% versus 35.5%), while at this age, limb trauma was more common during the COVID-19 period than before (5.6% versus 20.8%) (P = 0.043). In lean children, abdominal and pelvic trauma were mainly seen in the COVID-19 period (28.6% versus 2.6%) (P = 0.035).

Conclusion: Referrals of children from traumatic injuries decreased during the COVID-19 period. However, the main differences in the mechanism of trauma and the type and severity of traumatic injuries to children in this period emphasize the provision of specific guidelines for trauma management in children.

Pantalar dislocation means the simultaneous dislocation of the talocalcaneal, talonavicular, and tibiotalar joint. It is a rare injury comprising only 3.4% of major talar injuries. Treatment of closed Pantalar dislocation is controversial. However, the aim should be to attain a stable anatomic reduction of the Talus in the ankle joint. To prevent further damage to the skin and neurovascular structures, closed reduction of these dislocations should be performed as soon as possible. We report a case of Pantalar dislocation where we tried to reduce the talus both by closed and open methods but it was not possible to reduce the dislocation until the talonavicular joint was reduced first. Intending to improve the clinical knowledge of Pantalar dislocation, we want to convey our clinical experience and results from this rare dislocation.

Background: Evidence suggests that referral cases of traumatic injuries have decreased during the COVID-19 pandemic both in childhood and in adulthood. Still we have very little evidence of referrals due to traumatic brain injury among children during the COVID-19 outbreak. The present study aimed to describe epidemiological and clinical features of pediatric traumatic brain injuries.

Methods: This cross-sectional study was performed on all patients under 15 years with any evidence of head trauma, referring to Poursina teaching hospital, a referral center for trauma and road accidents in northern Iran. The patients' data were retrospectively collected by reviewing the hospital recorded files and the trauma-specific hospital information system.

Results: Of all 543 pediatric traumatic injuries referred to our hospital during the two pointed periods, 166 had any evidence of head and neck injuries leading to an overall prevalence rate of 30.6%. In this regard, the prevalence rate of head/neck injuries was estimated to be 140 out of 436 within a pre-COVID-19 period (32.1%) and 26 out of 107 within the COVID-19 period (24.3%) indicating no significant difference between the two time periods (P = 0.243). However, assessing the rate of head/neck injuries pre-COVID-19 and COVID-19 periods according to patients' age showed a higher rate of such injuries in pre-COVID-19 as compared to COVID-19 periods in patients aged less than two years (55.6% versus 37.5%, P = 0.013) as well as aged 2 to six years (45.8% versus 30.0%, P = 0.036).

Conclusion: The rate of admission of children due to traumatic brain injury during the COVID-19 period does not show a significant change compared to before, and only in children under 6 years of age a decrease in referrals due to brain trauma during the COVID-19 period was observed.

Background: Pedicle screw insertion at the level of the fractured vertebra has been shown to improve clinical and radiological outcomes in unstable thoracolumbar and lumbar fractures, albeit this requires further evidence. The study aims to evaluate the effect of pedicle screw placement on the fractured vertebra in such cases.

Methods: A prospective study included adult patients with thoracolumbar and lumbar fractures treated with short-segment posterior instrumentation with a pedicle screw into the fractured vertebra. Anterior vertebral body height loss, kyphotic angle and degree of spinal canal compromise were measured preoperatively and postoperatively in radiographs and CT scans. The neurological status was followed up for one year of the postoperative period.

Results: The study included a total of 30 patients. Five patients (16.7%) had grade C, three patients (10%) had grade D, and 22 patients (73.3%) had grade E neurological status. The mean (SD) preoperative kyphotic angle, vertebral body height and canal compromise were 5.54 (5.35), 39.67% (8.04), and 31.59% (10.62), respectively. Postoperatively there was a significant canal decompression, with a mean postoperative spinal canal compromise of 5.53% (SD=7.70; p-value <0.001). At the end of one year of follow-up, the radiological evaluation showed a correction of the kyphotic angle to 6.62 (SD=2.57; p-value <0.001), and the mean anterior vertebral body height was 70.38% (SD=11.25; p-value <0.001). At the end of one year, there was a significant overall neurological recovery with a final neurological status of grade D in 5 (16.7%) and grade E in 25 patients (83.3%). There was no significant association between canal decompression and neurology at the end of the one-year follow-up.

Conclusion: Unstable thoracolumbar and lumbar fractures surgically treated with short-segment fixation with an additional intermediate screw can achieve significant restoration of vertebral body height and correction of kyphotic angle without any added complications.

Emphysematous osteomyelitis is a rare but potentially fatal condition, which classically features intraosseous air on imaging without a direct communication with the atmosphere. Prompt recognition and treatment of the disease cannot be overstated as there is a high mortality rate associated with this condition. Here we report a case of emphysematous osteomyelitis of the calcaneus in a sixty-one-year-old male with diabetes mellitus and end-stage renal disease. This case of osteomyelitis was associated with an overlying necrotizing soft tissue infection, mandating an urgent below-knee amputation for source control. This case report is the first of its kind in the literature involving the calcaneous as emphysematous osteomyelitis more commonly involves the vertebral column. The purpose of this case report is to discuss the presentation and treatment of emphysematous osteomyelitis involving the calcaneous as well as provide a review of the current literature on this diagnosis.

Background: Postoperative delirium is a common complication with a high morbidity rate. This study was designed to consider the effectiveness of melatonin in prevention and treatment of postoperative delirium.

Methods: Seventy-two patients aged >60 years old with Abbreviated Mental Test (AMT) >8 scheduled for orthopedic surgery under spinal anesthesia, were randomly distributed equally to melatonin or placebo groups. In the melatonin group, the patients were given 5 mg melatonin capsules orally the night before surgery, the night of the operation, and two nights after the surgical operation at 9 pm. Likewise, in the placebo group, the patients received placebo in the same times. For diagnosis of postoperative delirium, the AMT test was used before the operation and three days after that. The Generalized estimating equations model (GEE) with logit link to Multivariate analysis was used in the study and P<0.05 was considered statistically significant.

Results: In total, 72 patients completed the study. Thirty-three patients (45.8%) were male with a mean (SD) age 71.4 (3.6) years. On the first day after the surgery, the incidence of delirium was significantly lower in the melatonin group compared to the placebo group (22.2% vs. 44.4%, P=0.046). On the second and third days after the surgery, the level of delirium in the melatonin group was also significantly lower than that in the placebo one. The GEE model showed a significant interaction between time and treatment groups.

Conclusion: The findings of the study showed that melatonin prevented delirium after the orthopedic surgeries in the elderly patients and could be useful for the patients as such.

Because few studies have assessed blood alcohol concentration (BAC)-positive risk conditions in trauma activation patients, this retrospective investigation pursued such an analysis. The parent database included consecutive trauma center admissions from January 21 to July 21 for 2018-2020. The supplementary electronic medical record audit of trauma activation patients aged 18-60 years (TA18-60) assessed alcohol misuse, smoking history, and serum bicarbonate levels. An alcohol misuse risk score was created by assigning a value of 0 (no) or 1 (yes) for each risk condition: 1) smoking history, 2) BAC-positive status, 3) BAC ≥ 100 mg/dL with Glasgow Coma Scale score (GCS) ≥ 13, 4) age ≥ 40 years, and 5) bicarbonate level ≥ 20 mmol/L in BAC-positive patients and summing the total score (range, 0-5). Of 2,076 patients, BAC testing occurred in 60.9% (n = 1,265). BAC positivity was greater in TA18-60 (36.9%) than in other patients (20.8%; P < 0.0001; odds ratio [OR] = 2.2). In the TA18-60 audit (n = 742), categorizations were available for BAC status, 98.5%; smoking history, 99.3%; alcohol misuse history, 99.5%; and bicarbonate level, 99.5%. BAC positivity was greater in smokers (41.3%) than in non-smokers (31.5%; P = 0.0061; OR = 1.5). BAC positivity was greater with alcohol misuse (87.0%) than without (17.7%; P < 0.0001; OR = 31.2). BAC-positive was associated with a greater proportion of bicarbonate levels < 20 mmol/L (52.0%) than BAC-negative (31.8%; P < 0.0001; OR = 2.3). The alcohol misuse proportion was greater with an alcohol misuse risk score of 3-5 (74.4% [142/191]) than with a risk score of 0-2 (10.4% [57/546]; P < 0.0001; OR = 24.9; area under the receiver operating characteristic curve = 0.89). This retrospective study demonstrates that BAC positivity is associated with TA18-60, smoking and alcohol misuse histories, and metabolic acidosis. An alcohol misuse history is associated with multiple risk conditions. Trauma center leadership should provide procedures to identify patients who are BAC-positive or have a positive smoking or alcohol misuse history. Then, such patients should be referred to care providers who can offer assistance and guidance for enhancing overall patient wellbeing.

Background: Fractures of the thoracolumbar and lumbar regions are very important. There is still debate on the use of braces after surgical operations. The current study aims to evaluate and report the outcomes of postoperative bracing following pedicle screw fixation in patients with thoracolumbar and lumbar fractures in Iran.

Methods: This is a clinical trial performed from 2012 to 2022 on 144 patients diagnosed with lumbar and thoracolumbar fractures. Demographic data of patients including age and gender were obtained. Patients' fractures were classified as Frankel (A to E) in terms of clinical and neurological manifestations. Patient's quality of life (QOL) was measured using the 36-Item Short Form Survey (SF-36). All patients underwent surgical fixation of the fracture. Patients were then randomized into two groups using Random Allocation Software. The first group received post-operation bracing and the second group did not receive braces. Thus, radiographic and clinical evaluation data of 1, 3, and 12 months after surgery were used to determine bone fusion.

Results: The most common mechanisms of trauma included falling from a height in 99 patients (68.7%), vehicle accidents in 39 patients (27.1%), and the most common fracture sites were the L1 vertebrae in 73 patients (50.7%), 111 patients (77.1%) had burst fractures, and 105 patients (72.3%) had no neurological defects (Frankel E). At the beginning of the study, there were no significant differences between the two groups regarding the mentioned data, patients' QOL, and pain severity. All patients (100%) had early mobilization. Most patients (85.4%) did not report persistent back pain 12 months after surgeries. 90.2% returned to their daily activities and all patients (100%) had full fusion based on radiologic data. The QOL and pain severity of patients improved significantly compared to baseline (P < 0.001 for both).

Conclusion: The use or non-use of braces did not affect the treatment results. As a result, patients who have received pedicle screw fixation for unstable thoracolumbar fractures do not require braces in the postoperative period.
