RESUMEN
BACKGROUND: The aim of our study is to assess the prognostic impact of the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) on 28-day mortality in patients admitted to the intensive care unit with crush syndrome following the Kahramanmaras earthquake in Türkiye. METHODS: A total of 63 adult patients with crush syndrome admitted to the intensive care unit after the earthquake were enrolled in this study. The medical records of the patients were examined using follow-up forms and the hospital data system. RESULTS: The mean age of the patients was 38.9±17.3 years, and the median time under debris was 31.5 hours. The 28-day mortality rate was 27%. In univariate generalized estimating equations (GEE) and other analyses, variables that are significant (or candidate variables) between 28-day mortality groups included age as a biological factor. These variables were included in the multivariate GEE model. The effects of continuous renal replacement therapy (CRRT), serum sodium concentration, Sequential Organ Failure Assessment (SOFA) score, and PLR on mortality were statistically significant. CONCLUSION: Elevated SOFA scores, the necessity for CRRT, increased serum sodium levels, and decreased PLR values are associated with increased 28-day mortality in patients with crush syndrome after an earthquake.

BACKGROUND Crush injury can result in crush syndrome (CS) when the pressure is released from the limb, resulting in ischemia-reperfusion injury and rhabdomyolysis. This retrospective study aimed to evaluate the demographics, clinical findings, management, and outcomes of 377 patients admitted as an emergency with a diagnosis of crush syndrome between February 6 and 16, 2023, following the Türkiye-Syria earthquakes. MATERIAL AND METHODS This observational study retrospectively analyzed CS patients admitted to the emergency service from February 6 to 16, 2023. We collected data on demographics, vital signs, time under debris, blood parameters, hemodialysis needs, outcomes, hospital stay duration, 7-day mortality, diagnoses, and treatments. RESULTS During the study period, 1682 earthquake victims were admitted, with 377 diagnosed with CS included in the study. The mean age was 33.51±0.89 years, with 51.7% male. The mean time under debris was 24.92±1.62 h, and the mean hospital stay was 34.39±1.20 days. Hemodialysis was required for 91 patients (24.1%), and 20 patients (5.3%) died. AKI developed in 23.1% (n=87) of the patients, with 30.5% (n=115) under debris for more than 24 h. Mortality, hospital stay, and AKI rates were higher in those requiring hemodialysis (P<0.001, P=0.003, and P<0.001, respectively). CONCLUSIONS The study highlights a high incidence of AKI, increased hemodialysis needs, and higher mortality in earthquake-related crush syndrome cases. Longer debris entrapment (over 24 h) was common. Early and aggressive fluid resuscitation, beginning in the field and continuing through hospital care, is crucial. Prioritizing this in disaster planning for field personnel is recommended.

BACKGROUND: Crush syndrome (CS) is characterized by high morbidity and mortality due to severe electrolyte disorders, circulatory dysfunction, and multiple organ failure, secondary to severe rhabdomyolysis and reperfusion injuries. Acute kidney injury (AKI) related to crush syndrome is one of the life-threatening complications and is the most frequent cause of death following earthquakes, other than trauma. We conducted a retrospective study to identify predictive parameters from clinical and laboratory data that aid in recognizing CS, assessing its severity, and evaluating acute kidney injury and amputation indications in patients. METHODS: We retrospectively evaluated the clinical data and laboratory follow-up of 33 patients treated for crush syndrome within the first two weeks following the February 6, 2023 earthquake. Patients who underwent surgery for crush syndrome but could not be followed post-surgery were excluded. Laboratory parameters were analyzed upon admission and then daily over an average seven-day follow-up. A p-value of <0.05 was considered statistically significant. Data analysis was performed using IBM SPSS Statistics 26.0 and R Studio software. RESULTS: Of the 33 patients, 17 were male and 16 were female. The incidence of AKI was 35.7%, 66.7%, and 100% in patients with injuries to one, two, and three extremities, respectively. A significant correlation was observed between total entrapment time and the duration of required dialysis days; AKI risk significantly increased with more than six hours of total entrapment time. Regarding the initial blood values upon hospital admission, a myoglobin level exceeding 2330 mg/dL demonstrated the highest sensitivity for predicting AKI. An initial uric acid level (>6.36 mg/dL) on admission had the highest specificity for predicting AKI. The initial myoglobin level (>3450 mg/dL) showed the highest sensitivity in predicting the need for amputation. Meanwhile, the mean creatine kinase (CK) level (>34800 U/L) exhibited the highest specificity but the lowest sensitivity for amputation prediction. CONCLUSION: The study analyzed the effectiveness and predictability of clinical and laboratory findings concerning amputation and acute kidney injury in crush syndrome resulting from earthquakes. Effective amputation management is a crucial factor influencing prognosis and survival in patients with earthquake-induced crush syndrome.

BACKGROUND: Double crush syndrome refers to a nerve in the proximal region being compressed, affecting its proximal segment. Instances of this syndrome involving ulnar and cubital canals during ulnar neuropathy are rare. Diagnosis solely through clinical examination is challenging. Although electromyography (EMG) and nerve conduction studies (NCS) can confirm neuropathy, they do not incorporate inching tests at the wrist, hindering diagnosis confirmation. We recently encountered eight cases of suspected double compression of ulnar nerve, reporting these cases along with a literature review. METHODS: The study included 5 males and 2 females, averaging 45.6 years old. Among them, 4 had trauma history, and preoperative McGowan stages varied. Ulnar neuropathy was confirmed in 7 cases at both cubital and ulnar canal locations. Surgery was performed for 4 cases, while conservative treatment continued for 3 cases. RESULTS: In 4 cases with wrist involvement, 2 showed ulnar nerve compression by a fibrous band, and 1 had nodular hyperplasia. Another case displayed ulnar nerve swelling with muscle covering. Among the 4 surgery cases, 2 improved from preoperative McGowan stage IIB to postoperative stage 0, with significant improvement in subjective satisfaction. The remaining 2 cases improved from stage IIB to IIA, respectively, with moderate improvement in subjective satisfaction. In the 3 cases receiving conservative treatment, satisfaction was significant in 1 case and moderate in 2 cases. Overall, there was improvement in hand function across all 7 cases. CONCLUSION: Typical outpatient examinations make it difficult to clearly differentiate the two sites, and EMG tests may not confirm diagnosis. Therefore, if a surgeon lacks suspicion of this condition, diagnosis becomes even more challenging. In cases with less than expected postoperative improvement in clinical symptoms of cubital tunnel syndrome, consideration of double crush syndrome is warranted. Additional tests and detailed EMG tests, including inching tests at the wrist, may be necessary. We aim to raise awareness double crush syndrome with ulnar nerve, reporting a total of 7 cases to support this concept.

BACKGROUND: Two earthquakes on 6 February 2023 destroyed 10 cities in Türkiye. We report our experience with pediatric victims during these catastrophes, with a focus on crush syndrome related-acute kidney injury (Crush-AKI) and death. METHOD: Web-based software was prepared. Patient demographics, time under rubble (TUR), admission laboratory data, dialysis, and kidney and overall outcomes were recorded. RESULTS: A total of 903 injured children (median age 11.62 years) were evaluated. Mean TUR was 13 h (interquartile range 32.5, max 240 h). Thirty-one of 32 patients with a TUR of >120 h survived. The patient who was rescued after 10 days survived. Two-thirds of the patients were given 50 mEq/L sodium bicarbonate in 0.45% sodium chloride solution on admission day. Fifty-eight percent of patients were given intravenous fluid (IVF) at a volume of 2000-3000 mL/m2 body surface area (BSA), 40% at 3000-4000 mL/m2 BSA and only 2% at >4000 mL/m2 BSA. A total of 425 patients had surgeries, and 48 suffered from major bleeding. Amputations were recorded in 96 patients. Eighty-two and 66 patients required ventilator and inotropic support, respectively. Crush-AKI developed in 314 patients (36% of all patients). In all, 189 patients were dialyzed. Age >15 years, creatine phosphokinase (CK) ≥20 950 U/L, TUR ≥10 h and the first-day IVF volume <3000-4000 mL/m2 BSA were associated with Crush-AKI development. Twenty-two deaths were recorded, 20 of 22 occurring in patients with Crush-AKI and within the first 4 days of admission. All patients admitted after 7 days survived. CONCLUSIONS: These are the most extensive pediatric kidney disaster data obtained after an earthquake. Serum CK level was significantly associated with Crush-AKI at the levels of >20 950 U/L, but not with death. Adolescent age and initial IVF of less than 3000-4000 mL/m2 BSA were also associated with Crush-AKI. Given that mildly injured victims can survive longer periods in the disaster field, we suggest uninterrupted rescue activity for at least 10 days.

BACKGROUND: On February 6th, 2023, two consecutive earthquakes struck southeastern Türkiye with magnitudes of 7.7 and 7.6, respectively. This study aimed to analyze the clinical and laboratory findings, as well as management of pediatric victims with Crush Syndrome (CS) and Acute Kidney Injury (AKI). METHODS: The study included pediatric earthquake victims who were presented to Mersin University Hospital. Clinical and laboratory characteristics of the patients were collected retrospectively. RESULTS: Among 649 patients, Crush injury (CI), CS and AKI was observed in 157, 59, and 17 patients, respectively. White blood cell count (12,870 [IQR: 9910-18700] vs. 10,545 [IQR: 8355-14057] /µL, P < 0.001), C-reactive protein (51.27 [IQR: 14.80-88.78] vs. 4.59 [1.04-18.25] mg/L, P < 0.001) and myoglobin levels (443.00 [IQR: 198.5-1759.35] vs. 17 [11.8-30.43] ng/ml) were higher in patients with CS, while their sodium (IQR: 134 [131-137] vs. 136 [134-138] mEq/L, P < 0.001) levels were lower compared to non-CS patients. An increase in myoglobin levels was identified as an independent risk factor for developing CS (OR = 1.017 [1.006-1.027]). Intravenous fluid replacement was administered to the patients with CS at a dose of 4000 cc/m2/day. Hypokalemia was observed in 51.9% of the CS patients on the third day. All patients with AKI showed improvement and no deaths were reported. CONCLUSIONS: Hyponatremia and increase in inflammation markers associated with CS may be observed. An increase in myoglobin levels was identified as a risk factor for CS. Hypokalemia may be seen as a complication of vigorous fluid therapy during hospitalization.

BACKGROUND: The purpose of this retrospective, single-institutional study was to report the clinical features and outcomes of orthopaedic injuries after the Kahramanmaras earthquake. METHODS: An institutional database review was conducted to evaluate the results of patients who applied to our hospital's emergency department after the Kahramanmaras earthquake. Trauma patients referred to orthopaedics and traumatology were identified. Patient records were checked for injury type, fracture site, treatment type (conservative or surgical), surgical technique, and outcome. Diagnosis with crush syndrome and the need for haemodialysis were also noted. Bedside fasciotomy was undertaken based on the urgency of the patient's condition, number of patients and the availability of the operating theatre. A team consisting of a trauma surgeon, a plastic surgeon, a board-certified physician in infectious disease, a reanimation specialist, a general surgeon and a nephrologist followed up with the patients. RESULTS: Within the first 7 days following the earthquake, 265 patients were admitted to the emergency department, and 112 (42.2%) of them were referred to orthopaedics and traumatology. There were 32 (28.5%) patients diagnosed with acute compartment syndrome. Fasciotomy was performed on 43 extremities of 32 patients. Of these extremities, 5 (11.6%) were upper and 38 (88.4%) were lower extremities.The surgeries of 16 (50%) of the patients who underwent fasciotomy were performed in the emergency department. There was no significant difference in terms of complications and outcomes between performing the fasciotomy at the bedside or in the operating theatre (p = 0.456). CONCLUSIONS: Fasciotomy appears to be a crucial surgical procedure for the care of earthquake causalities. Fasciotomy can be safely performed as a bedside procedure based on the urgency of the patient's condition as well as the availability of the operating theatre.

In the southeastern part of Turkey, two earthquakes measuring 7.7 and 7.8 on the Richter scale occurred within 9 h on 6 February 2023, causing 120,000 injuries and over 50,000 deaths. Evacuees were transferred to various secondary and tertiary hospitals as the health system and hospitals in the affected region were affected by the earthquake. Injuries were mostly caused by blunt trauma and/or prolonged bruising under rubble. The severity and pattern of traumatic injuries in earthquake victims differed from other trauma patients who were not affected by an earthquake. In addition to traumatic injuries that affected multiple body regions and systems, patients who were trapped under debris for long periods of time were also frequently found to have crush syndrome. Pulmonary thromboembolism and hypoxic-ischaemic brain injury were observed in some patients. In this review, we present the imaging findings of traumatic injuries in earthquake victims, emphasising the earthquake-related distinct injury types.

INTRODUCTION: It was aimed primarily to analyze the development of acute kidney injury (AKI) and treatment management in critically ill patients who developed rhabdomyolysis due to earthquake-related crush syndrome. METHODS: We evaluated 18 patients with crush syndrome who were admitted to the intensive care unit (ICU) after the great earthquake in February 2023 in Turkey. RESULTS: AKI occurred in 83% (n:15) of these patients after ICU admission (AKI-1; 16.6% [n:3], AKI-2; 16.6% [n:3], and AKI-3; 50% [n:9]). While the majority of patients who developed crush syndrome were treated with high volume intravenous hydration, only 33% (n:6) of all patients required renal replacement therapy. All patients who developed AKI had complete recovery in renal functions at the end of 2 months. CONCLUSION: There is no need for routine renal replacement therapy in the treatment of AKI, which is frequently seen in patients with crush syndrome. Most can be treated with high volumes of intravenous fluid.

ABSTRACT: Crush syndrome (CS), alternatively termed traumatic rhabdomyolysis, is a paramount posttraumatic complication. Given the infeasibility of conducting direct simulation research in humans, the role of animal models is pivotal. Regrettably, the dearth of standardized animal models persists. The objective of this study was to construct a repeatable standardized rat CS models and, based on this, simulate specific clinical scenarios. Methods: Using a self-developed multichannel intelligent small-animal crush injury platform, we applied a force of 5 kg to the hind limbs of 8-week-old rats (280-300 g), subjecting them to a continuous 12 h compression to establish the CS model. Continuous monitoring was conducted for both the lower limbs and the overall body status. After decompression, biochemical samples were collected at 3, 6, 12, and 24 h. In addition, we created a CS model after resection of the left kidney (UNx-CS), which was conceptualized to simulate a more challenging clinical scenario to investigate the physiological and pathological responses rats with renal insufficiency combined with crush injury. The results were compared with those of the normal CS model group. Results : Our experiments confirm the stability of the crush injury platform. We defined the standardized conditions for modeling and successfully established rats CS model in bulk. After 12 h of compression, only 40% of the rats in the CS group survived for 24 h. Systemically, there was clear evidence of insufficient perfusion, reflecting the progression of CS from localized to generalized. The injured limbs displayed swelling, localized perfusion deficits, and severe pathological alterations. Significant changes were observed in blood biochemical markers: aspartate transaminase, lactate dehydrogenase, K+, creatine kinase, creatinine, and blood urea nitrogen levels rose rapidly after decompression and were significantly higher than the sham group. The kidney demonstrated characteristic pathological changes consistent with established CS diagnostic criteria. Although the UNx-CS rat model did not exhibit significant biochemical differences and pathological scores when compared with the standard CS model, it did yield intriguing results with regard to kidney morphology. The UNx-CS group manifested a higher incidence of cortical and medullary protein casts compared with the NC-CS group. Conclusion: We developed and iteratively refined a novel digital platform, addressing the multiple uncontrollable variables that plagued prior models. This study validated the stability of the platform, defined the standardized conditions for modeling and successfully established the CS model with good repeatability in bulk. In addition, our innovative approach to model a clinically challenging scenario, the UNx-CS rat model. This offers an opportunity to delve deeper into understanding the combined effects of preexisting renal compromise and traumatic injury. In summary, the development of a standardized, reproducible CS model in rats represents a significant milestone in the study of Crush syndrome. This study is of paramount significance as it advances the standardization of the CS model, laying a solid foundation for subsequent studies in related domains, especially in CS-AKI.

Traumatic rhabdomyolysis is a systemic manifestation of muscle injury and can occur from various traumatic etiologies, including crush syndrome (CrshS) and compartment syndrome (CS). Although historically described in natural disaster survivors trapped under collapsed structures, the frequency of CrshS has increased in the setting of 'found down' patients from opioid overdoses. Signs and symptoms of the injured limb in CrshS may range from pressure-induced skin changes to neurologic deficits and paralysis. Although its pathophysiology differs from CS, severe injuries may lead to an associated CS. Identifying CS in a patient with CrshS can be difficult but is important to distinguish because it affects treatment. The degree of muscle damage, viability of the remaining muscular compartment, and presence of elevated compartment pressures dictate the need for surgical intervention in the form of fasciotomy. Surgical outcomes from CrshS and delayed CS result in similar high morbidity and surgical complications. This review defines and classifies the types of traumatic rhabdomyolysis and summarizes the outcomes to facilitate timely diagnosis and appropriate management for this population to reduce morbidity associated with these conditions.

Crush syndrome due to traumatic rhabdomyolysis is one of the most significant problems to occur following earthquakes. On February 6, 2023, millions of people in Turkey were affected by two consecutive Kahramanmaras earthquakes. The present study reports the analysis of clinical and laboratory findings of crush syndrome in pediatric earthquake victims admitted to our hospital from our region where the earthquake had a devastating effect. Clinical and laboratory findings concerning earthquake victims with crush syndrome were analyzed within the first week to determine what factors are predictive of kidney replacement therapy (KRT). The data of patients were retrospectively collected from medical records. A total of 310 children were admitted as earthquake victims to the pediatric emergency department. Ninety-seven (31%) of these patients had crush syndrome. Fifty-three (55%) of those with crush syndrome were female. The mean age was 10.9 ± 4.7 years, and the mean time under the rubble was 30.6 ± 23.8 h. Twenty-two patients (23%) required KRT. Hemodialysis was applied to 16 (73%) of them, and hemodiafiltration was applied to the other six (27%) in the pediatric intensive care unit. Regarding creatine kinase (CK) levels, the area under the receiver operating characteristic (ROC) curve (AUC) for predicting KRT was 0.905 (95% confidence interval [CI] 0.848-0.963; p < 0.001). The optimal cut-off value was 40,000 U/L with a sensitivity of 86% and a specificity of 83%. In terms of the percentage of body area crushed, the AUC for predicting KRT was 0.907 (95% CI 0.838-0.976; p < 0.001). The optimal cut-off value was 30% with a sensitivity of 86% and a specificity of 88%. Multiple logistic regression analysis showed that each 10% increase in body area crushed (OR 4.16, 95% CI 1.58-10.93, p = 0.004) and 1 mg/dl increase in the serum phosphorus level (OR 4.19, 95% CI 1.71-10.28, p = 0.002) were significant risk factors for dialysis treatment. CONCLUSIONS: Crush syndrome and kidney problems are common following disasters like earthquakes. Clinical and laboratory findings at admission can predict dialysis requirement in earthquake victims. While CK elevation, body area crushed percentage, and increased phosphorus level were predictive of dialysis treatment, time under the rubble was not. Even if the patients were under the rubble for a short time, acute kidney injury (AKI) may develop as a result of severe hypovolemia due to crush injuries, and patients may need KRT. WHAT IS KNOWN: â¢Crush syndrome after earthquakes needs to be treated carefully in victims and can cause AKI and mortality when not treated timely and appropriately. WHAT IS NEW: â¢CK level elevation, body area crushed percentage, and increased phosphorus level are predictive of dialysis treatment. â¢The time under the rubble may not be predictive of dialysis requirement.

INTRODUCTION: Earthquakes are sudden-onset natural disasters that are associated with substantial material damage, resulting in the collapse of built environment with a high rate of mortality, injury, and disability. Crush syndrome, which can be seen after devastating earthquakes, can lead to acute kidney injury (AKI) and patients may require amputation, fasciotomy, and dialysis. Supportive treatment has an important role in the prognosis of these patients. STUDY OBJECTIVE: The aim of this study was to investigate the demographic and clinical characteristics of traumatic earthquake survivors admitted to the emergency department (ED) of a hospital, which was close to the earthquake zone but not affected by the earthquake, after the February 6, 2023 Kahramanmaras (Turkey) earthquakes. MATERIALS AND METHODS: This study was conducted by retrospectively analyzing the data of 1,110 traumatized earthquake survivors admitted to the ED of a tertiary care university hospital from February 6th through February 20th, 2023. Age; gender; time of presentation; presence of comorbid diseases; ED triage category; duration of stay under debris; presence of additional trauma; laboratory tests; presence of AKI; presence of crush injury and injury sites; supportive treatment (fluid replacement and intravenous [IV] sodium bicarbonate); need for amputation, dialysis, and fasciotomy; duration of hospitalization; and outcome of ED were evaluated. RESULTS: Of the 1,110 traumatic victims in this study, 55.5% were female patients. The mean age of the patients was 45.94 (SD = 16.7) years; the youngest was 18 years old and the oldest was 95 years old. Crush injury was detected in 18.8% and AKI in 3.0% of the patients. Dialysis, amputation, and fasciotomy were required in 1.6%, 2.8%, and 1.4% of the patients, respectively. In total, 29.2% of patients were hospitalized, including 2.9% admitted to the intensive care unit (ICU) and 26.3% to the relevant ward. In total, 0.3% of the patients included in the study died at ED. CONCLUSION: Post-earthquake patients may present with crush injury, AKI may develop, and fasciotomy, amputation, and dialysis may be needed, so hospitals and EDs should be prepared for natural disasters such as earthquakes.

OBJECTIVE: The double crush syndrome describes a condition characterized by multifocal entrapment of a nerve. In the upper limb, the high prevalence of carpal tunnel syndrome makes it a common diagnosis of assumption in the setting of median neuropathy. More proximal compressions may tend to be overlooked, under-diagnosed and under-treated in the population. This study aims to map the prevalence of peripheral upper limb nerve compressions among patients undergoing peripheral nerve decompression. METHODS: A prospective case series was conducted on 183 patients undergoing peripheral nerve decompression in a private hand surgery clinic. Level(s) of nerve compression in the median, ulnar and radial nerves were determined by history and physical examination. The prevalence of each nerve compression syndrome or combination of syndromes was analyzed. RESULTS: A total of 320 upper limbs in 183 patients were analyzed. A double crush of the median nerve at the levels of the lacertus fibrosus and carpal tunnel was identified in 78% of upper limbs with median neuropathy, whereas isolated lacertus syndrome and carpal tunnel syndrome were present in only 5% and 17% of affected limbs respectively. Cubital tunnel syndrome affected 12.5% of upper limbs, and 80% of these had concomitant lacertus and carpal tunnel syndromes, compared to only 7.5% with isolated cubital tunnel syndrome. CONCLUSION: A high prevalence should prompt clinicians towards more routine assessment for double crush syndrome to avoid misdiagnosis, inadequate treatment, recurrence, and revision surgeries.

PURPOSE: Injuries increase the risk of venous thromboembolism (VTE). However, the literature on the management of anticoagulant therapy in pediatric patients with crush injury is limited. In this study, we aimed to share our experience about anticoagulant thromboprophylaxis in pediatric patients with earthquake-related crush syndrome. METHODS: This study included patients who were evaluated for VTE risk after the Turkey-Syria earthquake in 2023. Since there is no specific pediatric guideline for the prevention of VTE in trauma patients, risk assessment for VTE and decision for thromboprophylaxis was made by adapting the guideline for the prevention of perioperative VTE in adolescent patients. RESULTS: Forty-nine patients [25 males and 24 females] with earthquake-related crush syndrome had participated in the study. The median age of the patients was 13.5 (8.8-15.5) years. Seven patients (14.6%) who had no risk factors for thrombosis were considered to be at low risk and did not receive thromboprophylaxis. Thirteen patients (27.1%) with one risk factor for thrombosis were considered to be at moderate risk and 28 patients (58.3%) with two or more risk factors for thrombosis were considered to be at high risk. Moderate-risk patients (n = 8) and high-risk patients aged < 13 years (n = 11) received prophylactic enoxaparin if they could not be mobilized early, while all high-risk patients aged ≥ 13 years (n = 13) received prophylactic enoxaparin. CONCLUSION: With the decision-making algorithm for thyromboprophylaxis we used, we observed a VTE rate of 2.1% in pediatric patients with earthquake-related crush syndrome.

BACKGROUND: Thyroid hormone synthesis is a complex process in the human body. Although the thyroid gland is essential for thyroid hormone synthesis, skeletal muscles also have crucial roles in thyroid hormone metabolism due to the deiodinase activities of the muscle cells. Hypothyroidism-related myopathy is a well-known entity. However, systemic effects of acute myopathies, such as rhabdomyolysis, on thyroid hormone metabolism have not to date been fully clarified. METHODS: Fifty-three earthquake victims were evaluated retrospectively. We investigated the thyroid function tests (TFTs) among patients with creatine kinase (CK) levels higher than 10.000 U/L at admission. Fifteen patients had CK levels higher than 10.000 U/L and 12 of them had data of TFTs, including thyroid stimulating hormone (TSH), free T4 (FT4), and free T3 (FT3) during hospitalization. These patients were evaluated. RESULTS: TSH levels were increased in all seven patients who required HD due to severe crush syndrome. Decreased FT4 levels were detected in 71.4% of them. None of the five non-HD patients had increased TSH levels or reduced FT4 levels. During follow-up, all patients survived. Renal and thyroid functions were normalized during follow-up without thyroxin replacement in patients with no prior history of hypothyroidism. Moreover, TFTs were normalized in two patients with history of hypothyroidism under thyroxine treatment without dose adjustments. CONCLUSIONS: In severe forms of crush syndrome, temporary hypothyroidism might be seen. The exact mechanism underlying this entity is not well-known. Further clinical and experimental trials should be conducted to illuminate the mechanism of disrupted thyroid hormonogenesis in crush syndrome victims.

INTRODUCTION: Disasters and accidents have occurred with increasing frequency in recent years. Primary disasters have the potential to result in mass casualty events involving crush syndrome (CS) and other serious injuries. Prehospital providers and emergency clinicians stand on the front lines of these patients' evaluation and treatment. However, the bulk of our current knowledge, derived from historical data, has remained unchanged for over ten years. In addition, no evidence-based treatment has been established to date. OBJECTIVE: This narrative review aims to provide a focused overview of, and update on, CS for both prehospital providers and emergency clinicians. DISCUSSION: CS is a severe systemic manifestation of trauma and ischemia involving soft tissue, principally skeletal muscle, due to prolonged crushing of tissues. Among earthquake survivors, the reported incidence of CS is 2-15%, and mortality is reported to be up to 48%. Patients with CS can develop cardiac failure, kidney dysfunction, shock, systemic inflammation, and sepsis. In addition, late presentations include life-threatening systemic effects such as hypovolemic shock, hyperkalemia, metabolic acidosis, and disseminated intravascular coagulation. Immediately beginning treatment is the single most important factor in reducing the mortality of disaster-situation CS. In order to reduce complications from CS, early, aggressive resuscitation is recommended in prehospital settings, ideally even before extrication. However, in large-scale natural disasters, it is difficult to diagnose CS, and to reach and start treatments such as continuous administration of massive amounts of fluid, diuresis, and hemodialysis, on time. This may lead to delayed diagnosis of, and high on-site mortality from, CS. To overcome these challenges, new diagnostic and therapeutic modalities in the CS animal model have recently been advanced. CONCLUSIONS: Patient outcomes can be optimized by ensuring that prehospital providers and emergency clinicians maintain a comprehensive understanding of CS. The field is poised to undergo significant advances in coming years, given recent developments in what is considered possible both technologically and surgically; this only serves to further emphasize the importance of the field, and the need for ongoing research.

Crush syndrome induced by skeletal muscle compression causes fatal rhabdomyolysis-induced acute kidney injury (RIAKI) that requires intensive care, including hemodialysis. However, access to crucial medical supplies is highly limited while treating earthquake victims trapped under fallen buildings, lowering their chances of survival. Developing a compact, portable, and simple treatment method for RIAKI remains an important challenge. Based on our previous finding that RIAKI depends on leukocyte extracellular traps (ETs), we aimed to develop a novel medium-molecular-weight peptide to provide clinical treatment of Crush syndrome. We conducted a structure-activity relationship study to develop a new therapeutic peptide. Using human peripheral polymorphonuclear neutrophils, we identified a 12-amino acid peptide sequence (FK-12) that strongly inhibited neutrophil extracellular trap (NET) release in vitro and further modified it by alanine scanning to construct multiple peptide analogs that were screened for their NET inhibition ability. The clinical applicability and renal-protective effects of these analogs were evaluated in vivo using the rhabdomyolysis-induced AKI mouse model. One candidate drug [M10Hse(Me)], wherein the sulfur of Met10 is substituted by oxygen, exhibited excellent renal-protective effects and completely inhibited fatality in the RIAKI mouse model. Furthermore, we observed that both therapeutic and prophylactic administration of M10Hse(Me) markedly protected the renal function during the acute and chronic phases of RIAKI. In conclusion, we developed a novel medium-molecular-weight peptide that could potentially treat patients with rhabdomyolysis and protect their renal function, thereby increasing the survival rate of victims affected by Crush syndrome.

On February 6, two major earthquakes with magnitudes of 7.8 and 7.7 on the Richter scale hit Turkey and Northern Syria causing more than 50,000 deaths. In the immediate aftermath of the earthquakes, our major tertiary medical referral center received dozens of cases of crush syndrome, presenting with a variety of imaging findings. Crush syndrome is characterized by hypovolemia, hyperkalemia, and myoglobinuria that can lead to rapid death of victims, despite their survival of staying under wreckage for days. The typical triad of crush syndrome consists of the acute tubular necrosis, paralytic ileus, and third-space edema. In this article, we focus primarily on characteristic imaging findings of earthquake-related crush syndrome and divided them into two distinct subsections: myonecrosis, rapid hypovolemia, excessive third-space edema, acute tubular necrosis, and paralytic ileus, which are directly related to crush syndrome, and typical accompanying findings of earthquake-related crush syndrome. Lower extremity compression in earthquake survivors results in the typical third-space edema. In addition to the lower extremities, other skeletal muscle regions are also affected, especially rotator muscles, trapezius, and pectoral muscles. Although it may be relatively easy to better detect myonecrosis with contrast-enhanced CT scans, changing the windowing of the images may be helpful.
