Spinal cord injury can lead to important functional, psychological and social sequelae. Despite the progress in medicine and greater understanding of the pathophysiological events associated with a traumatic spinal cord injury, spinal cord injury is still associated with a high morbidity and mortality. The involvement of the autonomic nervous system has implications in acute and chronic stages of the injured spinal cord patients. The most frequent cardiovascular complications in the acute phase of the traumatic spinal lesions are bradyarrhythmia, hypotension, increased vasovagal reflexes, ventricular and supraventricular ectopic beats, venous stasis, and vasodilation. In the chronic phase, we find orthostatic hypotension, alteration of the arterial pressure and the regulation of the body temperature as well as alteration of the blood volume. The knowledge of the cardiovascular alterations is of vital importance for the management and rehabilitation of the patients with spinal cord injury. In this article, we present a critical review of medical literature.

水产养殖一直被认勾是贫穷国家农村地区居民获取食物/蛋白质的解决办法。它主要基于外来品种。一旦引进就会改变本地区系的动力学。水产养殖不仅改变淡水系统的生态,而且也导致社会关系的变化。到现在为止,水产养殖计划还没有充分地加以分析和探究。我们利用墨西哥中部一个城市的案例做分析,对农村地区在浅水池塘养殖鲤鱼对生态产生的影响和当地的社会效益作了评估。我们采用'环境权利'法,研定结果表明:①养殖鲤鱼增加了水的浑浊度,减少了本地鱼品种,减少穷人捕捞本地鱼的机会;②水产养殖主要对池塘主有利而非对穷苦的农民有利。主要原因是捕捞权利的变化引起的。我们的论是:假如想要降低对生态产生的负面影响以及改善农村地区人们的生活条件应重新审议水产养殖的政策目标和对收益的假设。

The pneumatization of regions such as the apex of the temporal crag, the mastoid cells and the perilaberytic region is considered physiological in adults. The process of craniocervical pneumatization in unhealthy adults derives from a dysfunction at the level of the eustachian tube, which provides a valve effect causing an increase in pressure at the level of the middle ear, forcing the entry of air into the dome of the skull through the opening of the occipitomastoidal suture. The process of standard pneumatization of the temporal bones, begins in the final weeks preceding birth, characterized by a decrease in the embryonic mesenchyme at the antrum level and progresses through childhood until adolescence, when the stone portion at the level of the rock is pneumatized;Normal variants have been reported, such as pneumatization that extends from the temporal scale to behind the sigmoid sinus. With regard to the process of hyperneumatization, several etiologies have been proposed that a congenital process versus an acquired process to develop this condition should be compared. The present illustrative case is a seventy-three years old male presented to the outpatient clinic with chronic recurrent occipital headache, already investigated by general practitioner for elevated blood pressure which was excluded. We had checked him to exclude the cervical spinal origin of the occipital headache which was then excluded too. This case scenario demonstrates the debate about how to deal with such cases and thus the review will bring the attention of those who take care of such radiological findings to keep in mind the possible causes and complications according to the reported cases till now. We concluded that the hyperpneumatization of the craniocervical junction is an uncommon radiological finding that is usually asymptomatic although it can entail serious complications in some instances, especially when it enlarges progressively, which may be due to an acquired process. Thus,

Hyponatremia is a common electrolyte disturbance usually observed in neurosurgical patients undergoing surgical management of traumatic, as well as, nontraumatic intracranial pathology. The spinal cord trauma is also associated with occasional development of such hyponatremia;it usually occurs within the first two-weeks of the injury. Hyponatremia can lead to alterations of consciousness, convulsions, coma, cardiac arrhythmias and on rare occasions, death. Authors present a practical oriented review of the literature.

Traumatic brain injuries are an important cause of morbidity and mortality around the world. These types of lesions are often associated with increased intracranial pressure and cerebral edema, proper management of this can reduce tissue damage of the brain and improve brain perfusion. The use of acetazolamide is not indicated in guidelines for the management of intracranial hypertension, which is used to a great extent for the management of idiopathic intracranial hypertension. However, it is not yet known in the management of traumatic intracranial hypertension.

BACKGROUND: Mild to moderate musculoskeletal trauma is a common cause for an emergency room visit, and frequent pain is one of the cardinal symptoms of consultation. The objective of this study is to assess the perception of a single subcutaneous dose of 50 mg tramadol for pain management in patients with mild to moderate musculoskeletal trauma, likewise to appraise the perception of pain by subcutaneous ***: A total of 77 patients, who met inclusion criteria, received a single subcutaneous dose of tramadol. Pain control was evaluated based on the verbal numerical pain scale(0–10) at baseline, 20 and 60 minutes; similarly, pain perception was evaluated secondary to subcutaneous injection of the ***: On admission, the average pain perceived by patients was 8; twenty minutes later, 89% of the patients reported fi ve or less, and after sixty minutes, 94% had three or less on the verbal numerical pain scale. Of the patients, 88% reported pain perception by verbal numeric scale of 3 or less by injection of the drug, and 6.5% required a second analgesic for pain control. Two events with drug administration(soft tissue infection and mild abdominal rectus injection) were ***: We conclude that a single subcutaneous dose of tramadol is a safe and effective option for the management of patients with mild to moderate pain and musculoskeletal disease in the emergency department.

On the north coast of present-day Peru, between the Andes and the Pacific Ocean, prospered approximately between 1000 BC and 1375 AD, several relevant cultures: Chavín (1000-200 BC), Vicús and Frías (200 BC - 300 AD), Moche (400 BC-700 AD), Sicán (700-1375 AD). These cultures are interconnected and characterized by a high metallurgical ability, demonstrated by the presence of beautiful artifacts on gold, silver and copper alloys. More than hundred metal artefacts from these cultures were analyzed with a portable equipment which uses the non-destructive and non-invasive technique of energy-dispersive X-ray fluorescence (EDXRF). Following objects were analyzed: (1) gold, silver and copper objects from the Chavín culture (Museo Municipal of Piura and and Museo Enrico Poli in Lima); (2) gold and silver objects from the Vicús and Frías cultures (Museo Municipal of Piura); (3) gold, silver and copper objects from the Moche culture ("Museo Tumbas Reales de Sipán", "Museo de Sitio de Huaca Rajada" in Lambayeque and Museo Enrico Poli in Lima); (4) gold, silver and copper objects from the Sicán culture (Museum of Sicán, Ferra?afe). Portable equipments were employed, mainly composed of a small size X-ray tube and a thermoelectrically cooled, small size, Si-PIN or Si-drift X-ray detectors. The main characteristics of the EDXRF-technique is of being non destructive and multi-elemental. Standard samples of gold and silver alloys were employed for calibration and quantitative analysis. The aims of this campaign of analysis were: (1) to analyze a large number of objects; (2) to differentiate gold, gilded copper and tumbaga (this last being a poor gold alloy enriched at the surface by depletion gilding); (3) to correlate, when possible, composition of analyzed alloys to the specific culture; (4) to determine a possible evolution of metallurgy; (5) to better determine characteristics and beginning time of tumbaga production. It was determined that the analyzed artefacts are composed
