    Abstract Background: Traumatic brain injury (TBI) is strongly associated with coagulopathy that occurs in 25-35% of patients. This complication is linked to higher mortality and morbidity. Recent lines of evidance have supported administration of fibrinogen concentrate (FC) in patients with severe TBI, while its efficacy remains controversial. In this study we aim to evaluate the effectiveness of serum fibrinogen level correction from 1.5 and 2.0 g/l to more than 2.0 g/l in patients with severe TBI undergoing traumatic cranial surgery.
    Method: This randomized, single-blind, placebo-controlled clinical trial included trauma patients who had abbreviated injury scale (AIS) more than 3 in head and below 3 in other organs. FC was administered intravenously to patients with severe TBI undergoing TBI to correct the fibrinogen level above 2 g/l. Patients were randomly assigned to FC and control groups. The amount of intra-operative blood loss, packed cell (PC) transfusion, formation of new intracranial hemorrhage, and hemovac drainage were compared between the two study groups.
    Results: Forty-seven of 65 participants received the study intervention within 40-112 min of admission. Intra-operative PC transfusion was higher in FC group (80%) compared to control group (55.5%) while the differance was not statistically significant (p > 0.05). Intra-operative blood loss was significantly higher in control group than FC group (P = 0.036). Chance of re-operation and new intracranial hematoma were not significantly different between two study groups.
    Conclusion: Early delivery of FC, decreases intraoperative bleeding. Although based on our findings it has no other effect on other parameters, further multicenter studies are recommended to investigate the role of early FC administration in management of post traumatic coagulopathy.

    Abstract Intervertebral disc degeneration (IDD) is the main cause of low back pain, which is a healthcare concern associated with high social and economic burden. The current medical and surgical therapies are inadequate and ineffective. Several miRNAs have been identified that modulate (via up- or down-regulation) the pathogenesis of IDD through various signaling pathways. Understanding the nature of this regulation and their signaling pathways will enable researchers to manipulate miRNA regulation to develop miRNA-based therapies. The development of miRNA-based therapies opens a future window through which to decrease the IDD process or regenerate the intervertebral disc. In the near future, the obstacles associated with miRNA-based therapies will be overcome and these therapies will move from the bench to the bedside.

    Abstract During the past 30 years, rate of coronary artery disease (CAD), as the main cause of sudden death (SD), has decreased more than rate of SD. Likewise, cause of SD remains elusive in not a trivial portion of its victims. One possible reason is attention to only one organ, the heart, as the cause of SD. In fact, SD literature focuses more on the heart, less on the brain, and seldom on both. A change is required. In this paper, we first review the pathological findings seen in heart autopsies of SD victims after psychological stressors such as physical assault victims without internal injuries. Then, we summarize new studies investigating brain areas, like the insula, whose malfunctions and injuries are related to SD. Next, we review prototypes of neurological diseases and psychological stressors associated with SD and look at heart failure (HF)-related SD providing evidence for the brain-heart connection. Finally, we propose a new look at SD risk factors considering both brain and heart in their association with SD, and review strategies for prevention of SD from this perspective.

    Abstract Introduction and importance: Scheuermann's kyphosis is a structural deformity of the thoracolumbar spine that is classified in typical (thoracic) and atypical (lumbar and thoracolumbar) Scheuermann's disease. Surgical intervention is reserved for those with progressive kyphosis, intractable pain and neurological impairment. Although, previous literature focuses on the correction of the thoracic kyphosis (TK), recent lines of evidence recommend considering all the sagittal balance parameters when performing a surgery. We herein, report a posterior-only approach in a patient with Scheuermann's kyphosis, considering all the sagittal balance parameters.
    Case presentation: The patient was a 17-year-old boy with a kyphotic deformity in the lumbar region, with urinary retention and upper back intractable pain. The preoperative physical examination was normal except for a kyphotic gait. The patient was first treated with thoracic lumbosacral orthoses (TLSO) brace that was not effective; consequently, the patient underwent posterior only approach (pedicular screw fixation along with Smith-Peterson osteotomy) with correction of the sagittal balance and kyphosis. The patient's sign and symptoms improved significantly. The surgery was uneventful and no complication was recorded. The 1-year follow-up revealed normal neurological examination and normal sagittal balance parameters.
    Clinical discussion: Atypical Scheuermann's kyphosis with neurological impairment and progressive kyphosis should be treated with surgical intervention.
    Conclusion: Considering the sagittal parameters of the spine, the surgical intervention should be designed to correct the kyphosis and the other indices of the sagittal balance. Posterior-only approach is safe and effective method for correction of the TK and improving the signs and symptoms of the patients.

    Abstract Introduction and importance: Odontoid fracture (OF) is among the most common and challenging cervical spine fractures in regards to the treatment and surgical approach. Atlanto-axial dislocation (AAD) is considered a significant complication after failed non-surgical treatment of OF. Traditionally, it requires anterior odontoidectomy followed by posterior C1-C2 reduction and fusion. In latest studies, Atlanto-axial joint (AAJ) remodeling in a posterior-only approach has got attention.
    Case presentation: We herein present a 30-year-old man with missed type-II OF, presenting with irreducible anterior AAD and progressive neurological deficit. Old non-united OF with dorsal callous formation, compressing spinal cord, was detected. The patient underwent correction of the deformity and reduction of the fracture utilizing the posterior-only approach. AAJ remodeling, callous release and C1-C2 fusion was performed in standard prone position, under fluoroscopic guide and intraoperative electrophysiological monitoring. The patient had uneventful surgery and postoperative course and was neurologically intact with appropriate alignment in 6-month follow-up.
    Clinical discussion: The irreducible AAD following type-II OF could be successfully treated with posterior-only approach (C1-C2 fusion).
    Conclusion: Type-II OF is considered unstable requiring surgical management. Close follow-up and appropriate patient education is mandatory in non-surgical treatment. Irreducible AAD has been managed with anterior odontoid resection and posterior fusion. Several complications of anterior surgery, makes posterior-only approach a noticeable choice.

    Abstract Background: Protective loop ileostomy is performed following low anterior resection (LAR) in patients with rectal cancer to reduce the complications of primary anastomosis. The optimal timing for ileostomy closure remains controversial. The aim of the current study was to compare the effects of early (<2 weeks) versus late (≥2 months) closure of the stoma in patients with rectal cancer undergoing LAR on surgical outcome and complications rates.
    Methods: This prospective cohort study was conducted in two referral centers in Shiraz, Iran, during a 2-year period. We have consecutively and prospectively included adult patients with rectal adenocarcinoma who underwent LAR followed by protective loop ileostomy in our center during the study period. The baseline, tumor characteristics and complication as well as outcome was recorded in a 1-year follow-up and was compared between early and late ileostomy closure.
    Results: Overall, 69 patients (32 in early and 37 in late group) were included. The mean age of the patients was 59.40 ± 9.30 years and there were 46 (66.7%) men and 23 (33.3%) women. Patients undergoing early closure of the ileostomy had significantly shorter operation duration (p<0.001) and lower intraoperative bleeding (p<0.001) compared to late ileostomy closure. There was no significant difference between two study groups regarding the complications. Early closure was also not found to be a predictive factor of post-ileostomy closure complications.
    Conclusion: Early closure (<2 weeks) of ileostomy after LAR in patients with rectal adenocarcinoma is a safe and feasible technique which is associated with favorable outcome.
