Injury of the carotid and vertebrobasilar arteries can cause brain infarction due to occlusion of brain blood flow. Case Presentation: Emergency medical service (EMS) brought a 4-year-old girl involved in a car accident to the emergency room. She had had seizure controlled by diazepam. She was unconscious and her Glasgow coma scale (GCS) score was eight. Early vital signs were stable. Her first brain CT scan showed a subdural hematoma (SDH). One day after admission to ICU, her GCS decreased to five; hence, a control brain CT was performed. The brain CT scan showed a brain infarction. Six days after admission, her status worsened and her GCS dropped to three and her pupils became dilated bilaterally and unresponsive to light; she was pronounced dead. Discussion: We present an uncommon case of posttraumatic brain infarction and synchronous SDH.https://www.traumamon.com/article_99902_3dbc3767fe02eb1b2721dbcf7cb98797.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Survey of 2582 Cases of Acute Orthopedic Trauma9990310.5812/traumamon.16215ENMehranSoleymanhaMohammadrezaMobayenKamranAsadiAlborzAdeliZahraHaghparast-Ghadim-LimudahiJournal Article19700101Background: Orthopedic injuries are among the most common causes of mortality, morbidity, hospitalization, and economic burden in societies. Objectives: In this research, we study the prevalence of different types of trauma requiring orthopedic surgery. Patients and Methods: We conducted a cross-sectional study on 2582 patients with acute orthopedic injuries admitted to the orthopedic emergency ward at the Poursina Hospital (a referral center in Guilan province (northern Iran), during December 2010 through September 2011. Patients were examined and the data collection form was filled for each patient. Data were analyzed by SPSS software version 19 and were listed in tables. Results: Of 2582 included cases, 1940 were male and 642 were female, with a mean age of 34.5 years. Most injuries were seen in the 25 to 44 year age group from rural areas. The highest frequency of trauma related to falls. On the other hand, bicycling and shooting had the lowest frequencies. There were 18 cases with limb amputation. Overall, 66.5% of patients had fractures, 5% had soft tissue lacerations, and 10% had dislocations. Conclusions: Identification of risk factors and methods of prevention is one of the most important duties of healthcare systems. Devising plans to minimize these risk factors and familiarizing people with them is prudent.https://www.traumamon.com/article_99903_f8cec21d4434239c656121b578f781b8.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101The Pattern of Fracture of Endodontically Treated Teeth9990410.5812/traumamon.17054ENChristopherIkeokwu UdoyeMatthewAsizide SedeHamidJafarzadehJournal Article19700101https://www.traumamon.com/article_99904_8e35e4199b0c90595814faaf747d9554.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Midterm Results of Treating Femoral Head Osteonecrosis With Autogenous Corticocancellous Bone Grafting9990510.5812/traumamon.17092ENManouchehrVahid FarahmandiMohammadrezaAbbasianFarshadSafdariMohammadEmami Moghaddam TehraniJournal Article19700101Background: Appropriate treatment of osteonecrosis of femoral head (ONFH) remains challenging. Objectives: Here, we report the results of treating these patients with auto-corticocancellous bone graft from iliac crest to overcome the need for early total hip arthroplasty (THA). Patients and Methods: There were 132 hips (96 patients) with ONFH. Association Research Circulation Osseous (ARCO) type II and III underwent auto-corticocancellous bone grafting from the iliac crest in the current prospective study. Before the operation and in the final postoperative visit, the pain intensity using visual analogue scale (VAS), range of hip motions and Harris hip score (HHS) were determined and compared. Patients were followed for 48.5 ± 17.9 months. Results: The shape of head and the joint space were preserved in 120 hips (90.9%). There were 12 hips in which the disease progressed to grade IV and resulted in THA in 10 of them. The pain intensity significantly decreased (6.3 ± 4.1 vs. 1.4 ± 2) and HHS (35.8 ± 15.3 vs. 79.5 ± 16.2) and range of motion (ROM) significantly improved after the operation (P < 0.001). Conclusions: Necrotic bone removal and filling the femoral head cavity with auto-corticocancellous bone graft from iliac crest is an effective femoral head preserving method in treating patients with precollapse stages of ONFH and preventing the need for early THA, especially in young active populations.https://www.traumamon.com/article_99905_66da29be610a622294c3366c250763e2.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Imaging-Based Diagnosis of Wernicke Encephalopathy: A Case Report9990610.5812/traumamon.17403ENHoseinDelavar KasmaeiAlirezaBaratlooMaryamSoleymaniZahraNasiriJournal Article19700101Introduction: Wernicke encephalopathy (WE) is a medical emergency characterized by ataxia, confusion, nystagmus and ophthalmoplegia resulting from thiamin deficiency. Alcoholism is the common cause for this disease. Case Presentation: A 41-year-old man was brought to our emergency department (ED) complaining of confusion. One week earlier he had started to experience severe nausea and vomiting followed by diplopia, dysarthria and also dysphagia. One day later he had experienced gait disturbance and progressive ataxia accompanied with confusion, apathy and disorientation. He had no history of alcoholism, drug abuse or previous surgery but had history of untreated Crohn disease. Just before arrival to our emergency department, he had been hospitalized in another center for about a week but all investigations had failed to provide a conclusive diagnosis. Upon admission to our ED, he was dysarthric and replied with inappropriate answers. On physical examination, bilateral horizontal nystagmus in lateral gaze, left abducens nerve palsy and upward gaze palsy were seen. Gag reflex was absent and plantar reflexes were upwards bilaterally. After reviewing all the previously performed management measures, MRI was performed and was consistent with the diagnosis of WE. Treatment with thiamine led to partial resolution of his upward gaze palsy and nystagmus on the first day. At the end of the third day of treatment, except for gate ataxia, all other symptoms completely resolved and he was fully conscious. After the fifth day his gait became normal and after one week he was discharged in good general condition. Discussion: After reviewing the current literature, it seems that brain MRI can be helpful in the diagnosis of WE in patients with the classic clinical trial in the absence of clear risk factors.https://www.traumamon.com/article_99906_9d15b77597d2e597087dab48a3c713f6.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Ultrasonographic Diagnosis of Suspected Hemopneumothorax in Trauma Patients9990710.5812/traumamon.17498ENSeyyed HosseinOjaghi HaghighiIdaAdimiSamadShams VahdatiRezaSarkhoshi KhiaviJournal Article19700101Background: Bleeding and trapped air in the pleural space are called hemothorax and pneumothorax, respectively. In cases where there are delays in diagnosis and treatment, the mortality rates due to hemopneumothorax can be significant. Hemopneumothorax is characterized by decreased lung sounds or chest percussion and subcutaneous emphysema. Diagnosis of pneumothorax and hemothorax can be achieved by portable chest X-ray (CXR), computed tomography (CT) scan, or ultrasonography. Portable CXR and CT-scans have their individual drawbacks. CXR creates a high percentage of false negative results, and a CT-scan is time consuming and less cost-effective; in addition, both modalities expose patients to radiation. Therefore, the introduction of ultrasonography as an easily available and highly accurate diagnostic modality has particular importance. Objectives: The aim of this study was to evaluate the sensitivity and specificity of ultrasonography in the diagnosis of pneumothorax and hemothorax in comparison with the other two methods, namely portable CXR and CT-scan. Patients and Methods: Patients (163) with multiple trauma who were suspected of having chest injuries, and who had indications for a chest CT-scan according to ATLS algorithms, were included in the study. All patients underwent portable CXR, CT-scan, and ultrasonography. Results: In total, 163 patients were included in this study; 29 patients had a pneumothorax, 24 patients had a hemothorax, and 23 patients had a hemopneumothorax confirmed. The study revealed that ultrasonography had a sensitivity of 96.15%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 98%, in the diagnosis of pneumothorax. The sensitivity for ultrasonography in the diagnosis of a hemothorax was 82.97%, with a specificity of 98.05%, a positive predictive value of 90%, and a negative predictive value of 92.66%. Portable CXR for pneumothorax detection had a sensitivity of 34.61%, a specificity of 97.95%, a positive predictive value of 90%, and a negative predictive value of 73.84%. In the detection of hemothorax, CXR had a sensitivity of 25.53%, a specificity of 95.14%, a positive predictive value of 70.58%, and a negative predictive value of 73.68%. Conclusions: Ultrasonography sensitivity and specificity for diagnosis of hemopneumothorax was high. The sensitivity of portable CXR was low despite its high specificity for the detection of hemothorax and pneumothorax.https://www.traumamon.com/article_99907_868a4b62023a2d9d38276152d8c5b8f9.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Prevalence of Low Back Pain Among Nurses: Predisposing Factors and Role of Work Place Violence9990810.5812/traumamon.17926ENMaryamRezaeeMohammadGhasemiJournal Article19700101Background: Ergonomic factors predispose nurses to low back pain (LBP). Few studies have clarified the role of workplace violence in LBP occurrence. Objectives: The present study was designed to investigate acute and chronic LBP in Iranian nurses and its association with exposure to physical violence as well as its personal and ergonomic risk factors. Materials and Methods: In this analytical cross sectional study, the rate of acute and chronic LBP and contributing factors were investigated among 1246 nurses using a validated questionnaire. Statistical analysis was performed by chi square, student t-test, and logistic regression, to determine the association between independent variables and LBP. Results: In total, 1246 nurses, consisting of 576 (46.23%) males and 670 (53.77%) females, were included. The mean age and the mean years of employment were 31.23 ± 5.33 and 16.18 ± 7.05, respectively. Both acute low back pain and chronic low back pain were associated with physical violence experience. Moreover, acute and chronic LBP were predicted by positive past history of LBP as well as two ergonomic factors, frequent bending and frequent carrying of patients. Conclusions: Besides a history of low back pain and ergonomic factors, physical violence may be considered a contributing factor for acute low back injuries. Special attention to all personal, occupational, and psychological risk factors is recommended.https://www.traumamon.com/article_99908_915464a6b655320681a2a2557623a88c.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Endoscopic Carpal Tunnel Release: A 5-Year Experience9990910.5812/traumamon.18058ENShahramNazeraniMohamad HosseinKalantar MotamediTinaNazeraniAmirSaraiiMohamad RezaKeramatiJournal Article19700101Background: Endoscopic carpal tunnel release (ECTR) has gained recognition as an alternative to the current gold standard, the open carpal tunnel release (OCTR). Detailed technical points for the ECTR have not been explained in the literature, especially for surgeons who are considering trying this technique. Objectives: In this paper, we present our 5-year experience with the ECTR and special emphasis will be placed on less frequently discussed technical points, such as the optimal site to make the skin incision and the signs to look for in a completely divided retinaculum. Patients and Methods: In this prospective nonrandomized clinical trial, 176 patients with carpal tunnel syndrome who underwent surgical operation using the Agee uni-portal endoscopic carpal tunnel release technique, over a period of 5 years, were included. The "Hand Questionnaire", a standard questionnaire for hand surgery, was used to evaluate the patients at one, three, six and twelve month post-operative time points. Pain and scar tenderness were measured using the visual analog scale system. We propose the ‘most proximally present wrist crease’ for the skin incision and the ‘proximal to distal sequential division of the retinaculum’ as our methods of choice. Two signs, named ‘railroad’ and ‘drop in’, are proposed and these will be discussed in detail as hallmarks of complete retinaculum release. Results: Of the 176 patients who underwent the ECTR operation, 164 cases (93.2%) had no or very little pain at the one year postoperative visit, and nearly all of the patients reported no relapse of symptoms at the previously mentioned postoperative time points. Patient satisfaction and functional recovery was comparable to other published ECTR studies, and showed better shortterm results of this technique over the OCTR. One deep seated infection, three cases of transient index finger paresthesia due to scope pressure on the median nerve, and one case of median nerve branch transection, were observed. Scar complications, including; tenderness, redness and pain, were significantly lower in the proximally placed incision in comparison with the distally placed incision (P < 0.005). Conclusions: The ‘most proximally present wrist crease’ and the ‘distal to proximal division of the retinaculum’ using the two signs of ‘railroad’ and ‘drop in’ to confirm a complete division of retinaculum are proposed techniques that should be considered in order to produce good outcomes in ECTR. The ‘railroad’ sign is the parallel standing of the retinaculum edges, and the ‘drop in’ sign is the dropping of the retinaculum edge into the scope denote a completely divided retinaculum.https://www.traumamon.com/article_99909_9f6361f4c785f2c3b0484b06e749d4f9.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Electrical Burn Injury: A Five-Year Survey of 682 Patients9991010.5812/traumamon.18748ENYaserGhavamiMohammad RezaMobayenRezaVaghardoostJournal Article19700101Background: Electrical burn is less prevalent in comparison to other forms of burn injuries, however this type of injury is considered as one of the most devastating due to high morbidity and mortality. Understanding the epidemiologic pattern of electrical burns helps determine the contributing factors leading to this type of injury. Objectives: Epidemiologic studies on electrical burn are scarce in Iran. This study was conducted to evaluate electrical burn injury at our center. Materials and Methods: Demographic data, etiology, burn percentage and other measures related to electrical burn injury of 682 electrical burn patients treated from 2007 to 2011 were collected and analyzed. Results: We assessed 682 electrical burn patients (~10.8% of all burn patients); the mean age was 29.4 years and 97.8% were males. The mean hospital stay was 18.5 days and the mean burn extent was 14.43%. Severe morbidities caused 17 (2.5%) deaths. Amputation was performed in 162 cases. The most common amputation site was the fingers (35%). Most victims were workers and employees and 68.5% of electrical burns occurred at their workplace; 72% of electrical burns were due to high voltage electrical current (more than 1000 V). There was a correlation between voltage and amputation (P = 0.001) and also between voltage and fasciotomy (P = 0.033), but there was no correlation between voltage and mortality (P = 0.131) Conclusions: Electrical burn injuries are still amongst the highest accident-related morbidities and mortalities. Educating the population about the dangers and hazards associated with improper use of electrical devices and instruments is imperative.https://www.traumamon.com/article_99910_c480b8093493c94a5d1d1d5b781836fe.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101National Getaways for the Weary Trauma Surgeon; Part 1: Kish Island9991110.5812/traumamon.21593ENMohammad HoseinKalantar MotamediJournal Article19700101https://www.traumamon.com/article_99911_5264a7e33397c1c43eb1e1dd67dc8c18.pdfOfficial Publication of the National Center for Trauma ResearchTrauma Monthly2251-746419420141101Corrigendum to: Changes in the Serum Level of Vitamin D During Healing of Tibial and Femoral Shaft Fractures [Published in Trauma Mon. 2014 February; 19(1): e10946]9991210.5812/traumamon.22699ENHosseinEttehadMehranSoleimanhaAhmadrezaMirbolookFereshtehMohammadiMohammadsadeghMousaviArdeshirShirangiHannanEbrahimiJournal Article19700101https://www.traumamon.com/article_99912_25a693f60c715610df2af0982a41e661.pdf
