The skydiving/parachuting sport which has recently gained popularity is also known for its accidents and injuries. However, there are a few studies related to its occupational ergonomic risks and occupational musculoskeletal diseases. It has been reported that the sudden hyperextension of the neck during the parachute opening, so called opening shock results in neck pain. It has been found that the jumpers are subjected to an average deceleration of 3-5 times the earth's gravitational acceleration (3-5 G) during parachute opening shock...

Ankylosing spinal disorders (ASD) tend to result in fractures and/or dislocations after minor trauma because of the altered biomechanical properties. The relative risk of traumatic vertebral fractures in patients with ankylosing spondylitis has been estimated as three times higher than in the general population. These spine traumas, which are located at cervical level in 81% of patients with ankylosing spondylitis, are complicated by neurological lesions in 65% of patients, due to the high inherent instability of these fractures...

Spinal cord ischemia and reperfusion (SCIR) injury can lead to neurologic dysfunction and paraplegia, which are serious complications after shock or thoracoabdominal aortic surgery. Autophagy is a fundamental cellular process in eukaryotes, and homeostasis of autophagic activities in the cytoplasm is critical for the maintenance of neuronal function. To date, no studies have addressed the involvement of autophagy in the regulation of motor neurons in the ventral horn of the spinal cord area following SCIR-induced spastic paralysis or the underlying mechanisms of this process...

In the CNS, microglia are activated in response to injury or infection and in neurodegenerative diseases. The endocytic and cell-signaling receptor, LDL receptor-related protein-1 (LRP1), is reported to suppress innate immunity in macrophages and oppose microglial activation. The goal of this study was to identify novel mechanisms by which LRP1 may regulate microglial activation. Using primary cultures of microglia isolated from mouse brains, we demonstrated that LRP1 gene-silencing increases expression of pro-inflammatory mediators; however, the observed response was modest...

Necrotizing Fasciitis (NF) is a rare, rapidly progressive severe bacterial soft tissue infection with a high mortality rate. NF classically involves the trunk, groin/perineum, lower limbs, and postoperative wound sites. NF secondary to spinal anaesthesia in a young postpartum female is extremely rare. Here we are describing a young postpartum female who underwent cesarean section for the delivery of child but developed NF of the back starting from the site of spinal needle insertion. She was referred to our center after 21 days of surgery with extensive NF...

Protein inclusions are a predominant molecular pathology found in numerous neurodegenerative diseases, including amyotrophic lateral sclerosis and Huntington's disease. Protein inclusions form in discrete areas of the brain characteristic to the type of neurodegenerative disease, and coincide with the death of neurons in that region (e.g. spinal cord motor neurons in amyotrophic lateral sclerosis). This suggests that the process of protein misfolding leading to inclusion formation is neurotoxic, and that cell-autonomous and non-cell autonomous mechanisms that maintain protein homeostasis (proteostasis) can, at times, be insufficient to prevent protein inclusion formation in the central nervous system...

BACKGROUND: During scuba diving, nitrogen dissolves into the body tissues due to elevated pressure under water. During a sudden drop in pressure due to a rapid return to the water surface, arterial gas embolism can arise from pulmonary barotrauma. In a later phase, nitrogen bubbles can also arise in the venous circulation (decompression sickness). Arterial bubbles can incur vascular damage, obstruction, hypoxia and infarction. CASE DESCRIPTION: A 53-year-old healthy sport diver presented at the emergency department in a hypovolemic shock with progressive paresis of all the extremities...

We have recently reported that a short course of morphine, starting 10days after sciatic chronic constriction injury (CCI), prolonged the duration of mechanical allodynia for months after morphine ceased. Maintenance of this morphine-induced persistent sensitization was dependent on spinal NOD-like receptor protein 3 (NLRP3) inflammasomes-protein complexes that proteolytically activate interleukin-1β (IL-1β) via caspase-1. However, it is still unclear how NLRP3 inflammasome signaling is maintained long after morphine is cleared...

This article reviews fluid therapy and medications in pediatric trauma. For resuscitation in the setting of hemorrhagic shock, isotonic crystalloid solution is the first-line agent of choice. Colloid solutions offer no additional benefit, introduce possible increased risks and cost more than crystalloids. Blood products, starting with pRBCs, should be introduced after 20-40 ml/kg of crystalloid has been administered if there is ongoing need for volume replacement. The use of a massive transfusion protocol of 1:1:1 (if >30 kg) or 30:20:20 (if <30 kg) of pRBCs:FFP:platelets is suggested after an initial 30 ml/kg of pRBcs have been administered...

OBJECTIVE: Scorpion (Hemiscorpius lepturus) stings are a public health concern in Iran, particularly in south and southwestern regions of Iran. The gold standard for the treatment of a scorpion sting is anti-venom therapy. However, immunotherapy can have serious side effects, such as anaphylactic shock (which can sometimes even lead to death). The aim of the current study was to demonstrate the protective effect of ozone against toxicity induced by Hemiscorpius lepturus (H. lepturus) venom in mice...

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...

More than 70 years ago, the phenomenon of "postural shock" in the supine position was described in healthy women in late pregnancy. Since then, avoidance of the supine position has become a key component of clinical practice. Indeed, performing pelvic tilt in mothers at term to avoid aortocaval compression is a universally adopted measure, particularly during cesarean delivery. The studies on which this practice is based are largely nonrandomized, utilized a mix of anesthetic techniques, and were conducted decades ago in the setting of avoidance of vasopressors...

BACKGROUND: Prophylactic anticoagulation may decrease the risk of venous thromboembolism (VTE) in patients with spine fractures following blunt trauma, but comes with the threat of postoperative bleeding in patients requiring stabilization of these fractures. The purpose of this study was to evaluate the impact of preoperative anticoagulation on VTE and bleeding complications in patients with blunt spine fractures requiring operative stabilization. METHODS: All patients with blunt spine fractures requiring operative stabilization over a 6-year period were identified...

Amyotrophic lateral sclerosis (ALS) and spinal and bulbar muscular atrophy (SBMA) are two motoneuron diseases (MNDs) characterized by aberrant protein behavior in affected cells. In familial ALS (fALS) and in SBMA specific gene mutations lead to the production of neurotoxic proteins or peptides prone to misfold, which then accumulate in form of aggregates. Notably, some of these proteins accumulate into aggregates also in sporadic ALS (sALS) even if not mutated. To prevent proteotoxic stresses detrimental to cells, misfolded and/or aggregated proteins must be rapidly removed by the protein quality control (PQC) system...
