RESUMO

Key Clinical Message: Arteriovenous malformations (AVM) are extremely rare on the face and especially on the lip. Lip can be more easily exposed to traumas due to their anatomical location. Especially superficial AV malformations are very susceptible to trauma and can bleed very seriously after being exposed to such effects. AVMs management generally based on their hemodynamic characteristics and growth modalities. The surgical treatment requires elaborate planning and multidisciplinary approach. When evaluating a mass with a clinical manifestation of lip swelling, ruling out a vascular anomaly before any intervention is also crucial. Abstract: Arteriovenous malformations (AVM) are abnormal fistulas between an artery and a vein, without an intervening capillary bed. AVM may occur everywhere in the body, with the brain being of particular concern, as AVM can be complicated by bleeding. Herein, we present the case of a patient with a very atypical AVM location consisting of a lip mass. Given the possibility of hemorrhage and airway obstruction, early detection and timely intervention are mandatory.

RESUMO

BACKGROUND: Mechanical bowel obstruction (MBO) is one of the principal pathologies requiring emergency surgery and a significant worldwide cause of morbidity. The identification of patients in whom bowel obstruction resolves spontaneously is important in terms of preventing unnecessary surgical interventions and future potential adhesions. The decision-making process is difficult in patients presenting without classic examination findings. METHODS: 36 female Sprague-Dawley rats randomly divided into six experimental groups. In Group 1, 3 and 5, laparotomy was performed, with blood and tissue specimens being collected after 1, 2 and 6 h, respectively. In Group 2, 4 and 6, the ileum segment was ligated following laparotomy, and blood and tissue specimens were collected after 1, 2 and 6 h, respectively. The ileum specimens were examined macroscopically, after which 1-cm sections were taken and examined in terms of histopathological changes. IMA and SCUBE-1 levels were determined for each group, and macro- and microscopic tissue examination findings were compared between the groups. RESULTS: Comparison within the groups exposed to waiting times of 1 h (groups 1 and 2), 2 h (groups 3 and 4) and 6 h (groups 5 and 6) revealed higher mean IMA and SCUBE-1 levels in rats undergoing ligation together with incision (groups 2, 4, and 6) compared to those undergoing laparotomy only (groups 1, 3, and 5). Correlation analysis was applied to determine the relationship between total scores obtained from histopathological examination and IMA and SCUBE-1 values. The analysis revealed strong, significant and positive correlation between histopathological examination scores and IMA (r=0.643, p=0.000) and SCUBE-1 (r=0.509, p=0.002) values. CONCLUSION: The study findings showed that both IMA and SCUBE-1 values increased in a strangulated MBO model in rats. We think that IMA and SCUBE-1 values can be used as a markers of damage in the early period in strangulated MBO, and that the patient's surgery requirement can thus be determined in the early period.

RESUMO

BACKGROUND AND STUDY AIMS: Esophageal burns due to ingestion of corrosive substances are frequently seen in both children and adults. However, there is no standard method of treatment to prevent associated mortality and morbidity. Therefore, this study aimed to evaluate the effects of known antioxidants, namely N-acetyl cysteine and ethyl pyruvate, on esophageal damage due to sodium hydroxide-induced corrosive burns. MATERIALS AND METHODS: Thirty-five female rats were randomly assigned to five equal groups. Group 1 was the sham group, while Group 2 was the control group. Group 3 received N-acetyl cysteine, Group 4 received ethyl pyruvate, and Group 5 received both N-acetyl cysteine and ethyl pyruvate. Rats in the "burn" groups were gavage-fed with 0.2mL of 25% NaOH. All esophagi were extracted on day 4 for histopathological evaluation. RESULTS: Total histopathological damage scores were evaluated at the end of the study. Groups 3 and 5 were significantly different from the control group in terms of total histopathological scores (p = 0.001), while no significant difference was seen with Group 4. Stenosis index results in groups 3 and 5 were similar to those seen with total histopathological scores (p = 0.004). CONCLUSION: N-acetyl cysteine, alone or in combination with ethyl pyruvate, may be useful in the treatment of esophageal damage associated with corrosive substances and in achieving histopathological improvement in an experimental setting.

RESUMO

INTRODUCTION: Cricothyroidotomy is an advanced and life-saving technique, but it is also a rare and a difficult procedure. The purpose of the present study was to produce a low-cost simulation model with realistic anatomic features to investigate its effectiveness in developing cricothyroidotomy skills. METHODS: This study was performed at a university simulation center with 57 second-year student paramedics and a cricothyroidotomy simulation model. Total scores were assessed using a checklist. This consisted of 13 steps and was scored as misapplication/omission=0, correct performance and timing with hesitation=1, and correct performance and timing without hesitation=2. One of these steps, local anesthesia of the area if time is available, was not performed owing to time limitations. The highest possible score was 24. Data are presented as mean±SD with range, as appropriate. Normal distribution was evaluated using the Kolmogorov-Smirnov test, Student t test, and Mann-Whitney U test, and correlation analysis was used for statistical analysis. RESULTS: Students completed the cricothyroidotomy procedure steps in 116±46 (55-238) s. At performance assessment, the score achieved was 12±5 (2-24). The highest total score of 24 was achieved by 3 students (5%). Total scores exhibited negative and significant correlation with procedure time (r=-0.403, P=0.002). CONCLUSIONS: The model developed in this study is an inexpensive and effective method that can be used in cricothyroidotomy training for student paramedics. We think that repeating the cricothyroidotomy procedure on the model will increase success levels.

RESUMO

OBJECTIVES: The aim of this study is to compare the diagnostic values of plasma levels of vascular adhesion protein-1 (VAP-1) and intestinal fatty acid-binding protein (I-FABP) for diagnosing acute mesenteric ischemia (AMI). METHODS: The study used a randomized, controlled experimental design. Forty-two female Sprague-Dawley rats were divided into three control groups and three ischemia groups. Plasma VAP-1 and I-FABP levels were measured, and the extent of ischemic damage was determined using a histopathological damage score in terminal ileum tissue samples. RESULTS: In the early phase of AMI (i.e. at the 30-min time point), VAP-1 levels did not differ between the control and ischemia groups (p > 0.05), but I-FABP levels were significantly higher in the ischaemia groups (p = 0.017). Although both VAP-1 and I-FABP levels increased in the ischaemia groups, only VAP-1 levels showed a significant increase compared to the control group at the 2-h time point (p = 0.011). Ischemic damages associated with AMI became the most prominent at the 6-h time point. During this phase, both VAP-1 and I-FABP levels were significantly higher in the ischemia groups than in the control groups (p = 0.007 and p = 0.002, respectively). Both VAP-1 and I-FABP levels showed a significant correlation with ischemic changes, but a higher correlation was observed for VAP-1 levels (r = 0.771). CONCLUSIONS: Both I-FABP and VAP-1 levels were useful for diagnosing AMI, but VAP-1 levels correlated better with the extent of ischaemic damage.

RESUMO

PURPOSE: To measure serum PTX3 levels in patients admitted with right lower quadrant pain to emergency department and to investigate whether this parameter will be helpful for the diagnosis of acute appendicitis. MATERIALS AND METHODS: This study was conducted with a group of 89 patients over 17 years of age who were admitted with the complaint of right lower quadrant pain to ED and had a preliminary diagnosis of acute appendicitis clinically and the control group of 31 healthy volunteers in a tertiary university hospital for 3 months. RESULTS: Median PTX3 levels were 3.28 (1.08-30.24) ng/mL in the acute appendicitis groups and 0.97 (0.34-2.62) ng/mL in the control group. A significant difference was observed between acute appendicitis groups and the control group (p < 0.05). CONCLUSION: PTX3 was found to be significantly higher in patient with acute appendicitis compared to the control group and the patients with non-specific abdominal pain. PTX3 can be used as an aid in the diagnosis of acute appendicitis.

RESUMO

OBJECTIVE: This study explores the potential use of drones in searching for and locating victims and of motorized transportation of search and rescue providers in a mountain environment using a simulation model. METHODS: This prospective randomized simulation study was performed in order to compare two different search and rescue techniques in searching for an unconscious victim on snow-covered ground. In the control arm, the Classical Line Search Technique (CLT) was used, in which the search is performed on foot and the victim is reached on foot. In the intervention arm, the Drone-snowmobile Technique (DST) was used, the search being performed by drone and the victim reached by snowmobile. The primary outcome of the study was the comparison of the two search and rescue techniques in terms of first human contact time. RESULTS: Twenty search and rescue operations were conducted in this study. Median time to arrival at the mannequin was 57.3min for CLT, compared to 8.9min for DST. The median value of the total searched area was 88,322.0m2 for CLT and 228,613.0m2 for DST. The median area searched per minute was 1489.6m2 for CLT and 32,979.9m2 for DST (p<0.01 for all comparisons). CONCLUSIONS: In conclusion, a wider area can be searched faster by drone using DST compared to the classical technique, and the victim can be located faster and reached earlier with rescuers transported by snowmobile.

RESUMO

OBJECTIVES: To develop a low-cost biomaterial-covered chest tube simulation model and assess its possible usefulness for developing the chest tube insertion skills among medical interns. Methods: This mannequin-based interventional study was performed in a University hospital setting. We included 63 physicians performing emergency medicine internship at the Faculty of Medicine, Karadeniz Technical University, Trabzon, Turkey, between January 2015 and March 2015. A dummy was prepared for training simulation using a display mannequin. Medical interns received instruction concerning pneumothorax and the chest tube procedure. A total of 63 medical interns participating in this interventional study were asked to insert a chest tube in a biomaterial-covered mannequin. A senior trainee scored their performance using a check list and the mean of the total scores was calculated (21 items; total score, 42). Results: The mean procedural score was 40.9 ± 1.3 of a possible 42. The maximum score of 42 was achieved by 39.7% of the medical interns, while another 33.3% achieved a score of 41. Of the participants, 85% succeeded in inserting the tube via an appropriate technique, achieving a score of 40 or more. Conclusion: Our results indicated that this model could be useful for effective training of medical interns for chest tube insertion, which is an important skill in emergency medicine. This biomaterial-covered model is inexpensive and its use can potentially be widened to improve training methods without significant financial demand.

RESUMO

Intracranial subdural hematoma developing following spinal anesthesia is a rare but serious complication. We describe a case of subdural hematoma developing following spinal anesthesia and diagnosed late. A female patient receiving spinal anesthesia for cesarean delivery 45 days prior to arrival at the emergency department presented to our hospital with non-severe headache persisting for 45 days after discharge. Computerized tomography (CT) of the brain performed due to long-term persisting headache resistant to medical treatment and a history of spinal intervention revealed a hypodense chronic subdural hematoma in the left frontoparietal area and a shift from left to right in midline structures. The patient was operated and discharged without sequelae on the 7th day postoperatively. Care must be taken over subdural hematoma in the presence of headache after spinal anesthesia persisting despite fluid intake and medical treatment and exceeding 48 h in duration, and diagnosis must not be delayed.

RESUMO

OBJECTIVE: Migraine and subarachnoid hemorrhage (SAH) patients present to emergency departments with the similar symptoms as headache, nausea, and vomiting. This study investigated whether the neutrophil-lymphocyte ratio (NLR) could distinguish patients with SAH from those with migraine. METHODS: This retrospective study was performed after research ethics committee approval. Data were gathered from the ED and neurology clinics of a university hospital between January 2015 and January 2016, from patients with symptoms of headache (primarily), nausea and vomiting. One hundred and twenty one with SAH, 123 patients with migraine and 987 with other primary headache syndromes were considered. Neutrophil-lymphocyte ratios (NLR-1) were compared between groups on admission. In SAH patients NLR taken on the 24th-30th hour of admission (NLR-2) was compared to admission NLR. RESULTS: NLR values, showed that the median NLR values of SAH patients were significantly higher than migraine and other headaches group values (p<0.001; p<0.001). There was no statistically significant difference between the NLR values of the migraine and control groups (p>0.05). An NLR cut-off value of 4.02 produced 85.95% sensitivity, 97.46% specificity, a 33.79 positive likelihood ratio (LR+), and a 0.14 negative likelihood ratio (LR-). A statistically significant increase was observed in median NLR-2 values compared to median NLR-1 values in SAH patients (p<0.001). CONCLUSION: In this retrospective analysis, NLR distinguished patients with SAH from those with migraine. Presence of SAH should be evaluated from discharged and readmitted patients (with headache symptoms) when an increase in NLR between initial and readmission levels is observed.

RESUMO

STUDY OBJECTIVE: To assess the effectiveness of nebulized fentanyl used for analgesia in renal colic. MATERIALS/METHODS: This research was planned as a randomized, blinded study in which prospectively collected data were analyzed retrospectively to compare nebulized and intravenous (iv) fentanyl therapies. Patients with renal colic with 'moderate' or worse pain on a four-point verbal pain score (VPS) or with pain of 20mm or above on a 100-mm visual analogue score (VAS) at time of presentation were randomized into iv fentanyl (n=62) or nebulized fentanyl (n=53) study groups. Decreases in VAS and VPS scores at 15 and 30min compared to baseline, rescue analgesia requirements and side-effects between the groups were compared. RESULTS: Both iv fentanyl and nebulized fentanyl provided effective analgesia in renal colic patients at the end of 30min. However, iv fentanyl provided more rapid and more effective analgesia than nebulized fentanyl. Patients receiving iv fentanyl had lower rescue analgesia requirements than those receiving nebulized fentanyl (37.1% vs 54.7%), although the difference was not statistically significant (p=0.058). In addition, side-effects were more common in the iv fentanyl group compared to the nebulized fentanyl group (22.1% vs 9.4%), although the difference was also not significant (p=0.058). CONCLUSION: Nebulized fentanyl provides effective analgesia in patients with renal colic. However, iv fentanyl exhibits more rapid and more powerful analgesic effects than nebulized fentanyl. Nonetheless, due to its ease of use and few potential risks and side-effects the nebulized form can be used as an alternative in renal colic.

RESUMO

PURPOSE: To investigate the difference in pentraxin 3 (PTX 3) levels between patients with pulmonary contusion and healthy volunteers. MATERIALS AND METHODS: This study was conducted with a group of 20 trauma patients diagnosed with pulmonary contusion and 30 healthy individuals enrolled as a control group in a tertiary university hospital. RESULTS: Median PTX 3 levels were 7.05 (3.29-13.1), ng/ml in the contusion group and 1.03 (0.7-1.58) ng/ml in the control group. PTX 3 titers were significantly higher in patients with pulmonary contusion compared to those of the control group (p<0.001). An area under the curve (AUC) value of 0.968 investigated using ROC analysis to determine the diagnostic value of the PTX-3 in pulmonary contusion patients was measured. A PTX-3 cut-off value of 2.06 produced 95.5% sensitivity and 86.7% specificity. CONCLUSION: PTX 3 levels in pulmonary contusion increased significantly compared to the healthy control group. If supported by wider series, PTX 3 may be expected to be capable of use as a marker in pulmonary contusion.

RESUMO

OBJECTIVE: Neuroleptic malignant syndrome (NMS) is a neurological emergency rarely encountered in clinical practice but with a high mortality rate. Cases associated with atypical antipsychotic use or termination of dopamine agonists have been seen in recent years. The purpose of this study was to assess the presence of risk factors for mortality by investigating all clinical and laboratory characteristics of cases with NMS. MATERIAL AND METHODS: This descriptive, cross-sectional study retrospectively investigated all clinical and laboratory characteristics by scanning the ICD-10 codes of patients presenting to the XXXX Faculty of Medicine Emergency Department and diagnosed with NMS between 2006 and 2016. Patients were divided into surviving and non-surviving groups, and the data elicited were subjected to statistical comparisons. RESULTS: The mean age of the 18 patients diagnosed with NMS was 46.9 ± 4.8 years, and 50% were women. In addition to antipsychotics among the drugs leading to NMS, the syndrome also developed as a result of levodopa withdrawal in three patients and metoclopramide use in one patient. Statistically significant differences were determined between the surviving and non-surviving patients in terms of blood pressure, blood urea nitrogen (BUN), creatine kinase (CK) and mean platelet volume (MPV) values (p ≤ 0.05). CONCLUSION: In this study the most common agent that cause NMS was atypical antipsychotics. Also advanced age, increased blood pressure and serum CK, BUN and MPV values were identified as potential risk factors for mortality in NMS.

RESUMO

OBJECTIVE: The objective was to compare the protective effects of N-acetylcysteine (NAC) plus normal saline (NS), sodium bicarbonate (NaHCO3 ) plus NS, and NS alone in the prevention of contrast-induced nephropathy (CIN) after computed tomography pulmonary angiography (CTPA) in emergency patients. METHODS: This study was planned as a randomized, controlled clinical research. Patients undergoing contrast-enhanced CTPA on suspicion of pulmonary embolism (PE) in the emergency department and with at least one risk factor for development of CIN were included in one of three different prophylaxis groups. The groups received 3 mL/kg intravenous (IV) NAC+NS or NaHCO3 +NS solution or NS alone 1 hour before CTPA and 1 mL/kg IV per hour for a minimum of 6 hours after CTPA. CIN was evaluated as the primary outcome and moderate or severe renal insufficiency and in-hospital mortality as secondary outcomes. RESULTS: A total of 257 patients were enrolled in the study. The total level of CIN development was 23.7% (61/257), the level of moderate and severe renal failure was 12.5% (32/257), and the in-hospital mortality rate was 12.8% (33/257). Rates of CIN development in the drug groups were 23.5% in the NAC group (20/85), 21.2% (18/85) in the NaHCO3 group, and 26.4% in the NS group (23/87). Rates of development of moderate or severe renal insufficiency were 9.4% in the NAC group (8/85), 10.6% in the NaHCO3 group (9/85), and 17.2% in the NS group (15/87). In-hospital mortality rates were 12.9% in the NAC group (11/85), 11.8% in the NaHCO3 group (10/85), and 13.8% in the NS group (12/87). No difference was determined between the drug groups in terms of CIN, moderate or severe renal injury, or hospital mortality. CONCLUSIONS: Our results indicate that there is a high risk of CIN in patients with suspected PE despite three different types of prophylaxis being administered, and no statistically significant differences were observed among prophylactic NAC, NaHCO3 , and NS in prevention of CIN following contrast-enhanced CTPA.

RESUMO

INTRODUCTION: The aim of this study was to evaluate patients presenting to the emergency department (ED) with wrist trauma using physical examination findings and functional tests and to identify findings with high sensitivity and specificity among the parameters assessed in patients with fracture in the wrist. The ultimate objective was thus to establish a reliable and widely usable clinical decision rule for determining the necessity of radiography in wrist trauma. METHODS: This prospective, multicenter study was performed in 8 hospitals. The relation between radiologically determined fracture and clinical findings consisting of physical examination findings and functional tests was assessed in terms of whether or not these were markers of radiography requirement, with the aim of identifying predictive values for fracture. RESULTS: A total of 603 eligible trauma patients presented to the participating EDs during the study period. Fracture was identified in 24.5% of patients (n = 148). The 4-way combination with the highest sensitivity was identified as axial compression and the positive distal radioulnar drawer test, and pain with radial deviation and dorsal flexion. Sensitivity at distal ulna palpation was added as a fifth parameter, and sensitivity and negative predictive value thus increased to 100%. CONCLUSION: With their 100% sensitivity and 100% negative predictive values, the Karadeniz wrist rules may represent a clinical decision rule that can be used in practice in EDs. If all 5 findings are negative, there is no indication for wrist radiography.

RESUMO

OBJECTIVE: To investigate the potential diagnostic value of plasma signal peptide, CUB (complement proteins C1r/C1s, Uegf, Bmp1) domain, epidermal growth factor (EGF)-like 1 (SCUBE1) protein in experimentally induced testicular torsion (TT). MATERIALS AND METHODS: In this randomized, controlled, experimental study, 24 mature male Wistar rats were divided into four groups: 2- and 4-hour control (groups I and III, respectively), and 2- and 4-hour torsion (groups II and IV, respectively) groups. Torsion was performed by rotating the left testis 720° clockwise and maintained by fixing the testis. Plasma SCUBE1 levels and histopathological damage scores were compared. RESULTS: There was significantly greater histopathological damage in the 4-hour torsion group compared with the other groups. SCUBE1 levels in this group were also higher than those in the other groups, and the difference was significant. There were significant correlations between histopathological scores and SCUBE1 levels. CONCLUSION: SCUBE1, a novel marker of platelet activation, is elevated in TT. According to our results, platelet activation may play an important pathological role in tissue injury associated with testicular ischemia. Plasma SCUBE1 measurement may have diagnostic, therapeutic, or prognostic value in TT.

RESUMO

OBJECTIVES: The purpose of this study was to evaluate predetermined physical examination and function tests recommended to identify severe injury among patients presenting with wrist injury to the emergency department and to establish a reliable clinical decision rule capable of determining the need for radiography in wrist injuries. MATERIALS AND METHODS: This was a multicenter prospective derivation study of wrist injuries. All patients were assessed in terms of mechanism of trauma, inspection findings, heart rate, sensitivity at palpation, presence of pain with active movement, grasp strength, and functional tests using an examination form under main headings. Sensitivity, specificity, and positive and negative predictive values were expressed for each sign and each examination finding. RESULTS: One hundred nineteen adult patients were enrolled during the 6-month study period. Fracture was identified in 24.3% (n = 29). Presence of pain on the radial deviation, dorsal flexion, distal radioulnar drawer, and axial compression tests exhibited high sensitivity (82.8%, 89.7%, 82.8%, and 86.2%, respectively) and high negative predictive values (88.6%, 81.3%, 87.5%, and 93.6%, respectively) for wrist fracture. Sensitivity of 96.6% was observed when these 4 tests were evaluated together. CONCLUSIONS: The presence of one of these examination findings increases the likelihood of fracture and is adequate to recommend wrist radiography. In addition, there is a strong possibility of radiography being unnecessary if all 4 test results are negative in patients presenting with wrist injury, potentially preventing many nonessential radiographs being performed.

RESUMO

OBJECTIVES: Carbon monoxide is a potentially fatal form of poisoning. The exact incidence is unclear, due to cases being undiagnosed or reported as fewer than the real number. Hyperbaric oxygen therapy (HBOT) is of proven efficacy in the treatment of CO intoxication. The purpose of this study was to describe the general characteristics of carbon monoxide (CO) intoxications presenting to the emergency department and to investigate troponin I values and the effectiveness of hyperbaric oxygen therapy (HBOT) in these patients. MATERIAL AND METHODS: Patients presenting to the emergency department with CO intoxication over one year and patients with such intoxications receiving HBOT were examined retrospectively. RESULTS: One hundred seventy-one patients were included; 140 (81.9%) were poisoned by stoves, 18 (10.5%) by hot water boilers and 10 in (5.8%) by fires. COHb levels were normal in 49 of the 163 patients whose values were investigated, and were elevated in 114 patients. Mean COHb value was 16.6. Troponin I values were investigated in 112 patients. These were normal in 86 patients and elevated in 26. Mean troponin I value was 0.38 ng/ml. One hundred twenty-three of the 171 patients in the study were discharged in a healthy condition after receiving normobaric oxygen therapy, while 48 patients received HBOT. Forty-two (87.5%) of the patients receiving HBOT were discharged in a healthy condition while sequelae persisted in five (10.4%). One patient died after 15 session of HBOT. CONCLUSION: Although elevated carboxyhemoglobin confirms diagnosis of CO intoxication, normal levels do not exclude it. Troponin I levels may rise in CO intoxication. No significant relation was observed between carboxyhemoglobin and receipt of HBOT. A significant correlation was seen, however, between troponin I levels and receipt of HBOT.

RESUMO

Acute cerebellitis is a rare inflammatory disease involving the cerebellum and is characterized by acute compromise of cerebellar functions. It most frequently originates from infectious causes, although cases of cerebellitis associated with other causes have also been reported. This report discusses a case of cerebellitis developing in a 4-year-old girl who had to be intubated after accidental ingestion of tricyclic antidepressant. There are no previous reports of cerebellitis after tricyclic antidepressant. This case shows that cerebellitis can develop in patients with poisoning of this kind.

RESUMO

OBJECTIVE: To establish the value of ischemia-modified albumin levels in the determination of the long-term results of testicular torsion/detorsion-associated ischemia-reperfusion injury. METHODS: Eighteen mature male Wistar rats were divided randomly into 3 groups (n = 6 for each group): control, acute torsion/detorsion (T/D) group, and long-term T/D. In the control group, scrotal incision only was performed; in the acute T/D group, after 4 hours of torsion, detorsion was performed and maintained for 2 hours. Blood samples and testicular tissue samples were taken after 2 hours of detorsion. The same T/D procedures were performed in the long-term T/D group. The long-term T/D groups were kept alive for 2 months, and samples were taken at 2 months post procedure. Serum ischemia-modified albumin, serum and tissue malondialdehyde levels, and histopathological damage scores were measured. RESULTS: Serum ischemia-modified albumin levels were significantly higher compared with the control group, in the acute-term T/D (P = .004). This elevation remained pronounced in the long term compared with the control group and acute period (P = .008 and P = .017, respectively). There was a significant negative correlation between serum ischemia-modified albumin levels and histopathological injury score in both the torsioned and contralateral testes (r = -.929, P < .0001 and r = -.560, P = .02, respectively). CONCLUSION: Ischemia-modified albumin is a valuable parameter in terms of reflecting testis injury in testicular torsion in both the acute period and the long term. It therefore has the potential to be used as data with predictive value regarding patients' fertility capacities.
