Among the functions that it performs are the following: the metabolism of lipids and carbohydrates, and the syn thesis of proteins, coagulation factors, and biliary salts. Eighty percent of the hepatic paren chyma is made up of hepatocytes, which are the cells mainly responsible for maintaining every function that the liver in its entirety requires to sustain the bodys normal physiologi cal functions in general. The hepato cytes are disposed in the liver in groups denominated lobules, which have a central orifice comprised of the bile duct and by means of which the biliary salts are excreted. The anatom ical loss of the structure of the hepatic lobule is considered a symptom of severe damage to the liver; it can be accompanied by partial or total loss of some physiological function, as in the case of alcohol-related hepatic cirrhosis. Hepatic regeneration Liver regeneration is a fundamental response of the liver on encountering tissue damage. The complex interaction of factors that determine this response involves a stimulus (experi 2013 Morales-Gonzlez et al. This proliferation depends on the hepatocytes, epithelial bile cells, Kupffer cells, and Ito cells. The mechanisms of hepatic growth have been studied in detail in experimental models. In the latter, regeneration is induced whether by tissue resection (partial hepatectomy) or by death of the hepatocytes (toxic damage). Evidence that there is a humoral growth factor of the hepatocyte has been observed in animal models and in patients with liver disease from the 1980s. Ethanol On being ingested, alcohol (also called ethanol) produces a series of biochemical reactions that lead to the affectation of numerous organs involving economy, having as the endpoint the development of hepatic diseases such as alcoholic hepatitis and cirrhosis. Despite that much is known about the physiopathological mechanisms that trigger ethanol within the or ganism, it has been observed that a sole mechanism of damage cannot fully explain all of the adverse effects that ethanol produces in the organism or in one organ in particular. A factor that is referred as playing a central role in the many adverse effects that ethanol exerts on the organism and that has been the focus of attention of many researchers is the excessive generation of molecules called free radicals, which can produce a condition known as oxidative stress, which triggers diverse alterations in the cells biochemical processes that can finally activate the mechanism of programmed cell death, also known as apoptosis. Of particular importance for the objective of this chapter is the focus on a particular class of free radicals that are oxygen derivatives, because these are the main chemical entities that are produced within the organism and that affect it in general. Ethanol metabolism Ethanol is absorbed rapidly in the gastrointestinal tract; the surface of greatest adsorption is the first portion of the small intestine with 70%; 20% is absorbed in the stomach, and the re mainder, in the colon. Under optimal conditions, 80-90% of the ingested dose is completely absorbed within 60 minutes. Gender difference is a factor that modifies the distributed etha nol volume; this is due to its hydrosolubility and to that it is not distributed in body fats, which explains why in females this parameter is found diminished compared with males. Ethanol is eliminated mainly (> 90%) by the liver through the enzymatic oxidation path way; 5-10% is excreted without changes by the kidneys, lungs, and in sweat [14, 30]. Liver regeneration and ethanol Ethanol is a well known hepatotoxic xenobiotic because hepatotoxicity has been well docu mented in humans as well as in animals. Although aspects concerning the pathogenesis of liver damage have been widely studied, it is known that liver regeneration restores the func tional hepatic mass after hepatic damage caused by toxins. Suppression of the regenerating capacity of the liver by ethanol is the major factor of liver damage. Although the effects of acute or chronic administration of ethanol on the proliferative capacity of the liver to re generate itself has been studied, the precise mechanism by which ethanol affects hepatocel lular function and the regenerative process are poorly explained.
Enlarged lymph nodes associated with anthracotic pigment 20 mcg ipratropium free shipping, thyroiditis and malignant thyroid disease can also confound parathyroid localization cheap ipratropium 20mcg with amex. However cheap 20 mcg ipratropium amex, as previously mentioned, even a study that fails to reveal a parathyroid adenoma may be useful by identifying thyroid disease in a patient that is being considered for surgery for hyperparathyroidism. Incidence of concurrent thyroid disease has been reported as high as 51% in patients being considered for parathyroid surgery, and the incidence of thyroid malignancy as 2-6%. Sensitivity for sestamibi scanning has been reported in the range of 68-95% for single adenomas, with one meta-analysis putting it at 88%. Sensitivity is far less for multi-gland disease and has been reported at 44% for hyperplasia and 30% for double parathyroid adenomas. Again, sensitivity drops for multi-gland disease and has been reported at 16% for parathyroid hyperplasia and 35% in double adenomas. The surgeon may use both the functional information from scintigraphy along with the anatomic information from ultrasound. Additionally, ectopic glands that are missed by ultrasonography may be detected with scintigraphy, while ultrasonography may detect thyroid abnormalities helping to interpret scintigraphy findings. Combining these techniques results in a sensitivity of 74- 95% for single gland disease. However, the sensitivity for double adenomas is 60%, and multi-gland disease is only accurately predicted 30% of the time by these techniques. When the two imaging studies are concordant (which occurs in 50-60% of cases) the sensitivity is in the range of 94-99%. Combined ultrasonography and sestamibi is the preferred imaging method of most parathyroid surgeons. When combined with ultrasonography, it results in only slightly increased sensitivity compared with ultrasonography alone. Benefits may be greater in the subset of patients with multi-gland disease or goiter, but such combination scans require further investigation. Typically, pre-operative and pre-incision blood samples are taken for baseline measurements. After excision of all of the suspected diseased tissue, samples are usually sent at 0, 5, and 10 minutes. If it does not occur, further cervical exploration is performed to identify additional parathyroid tissue that may be causing the patients hyperparathyroidism, and the suspicion for multi-gland disease increases. If the 50% criterion is met, surgical success rates (as measured by postoperative normocalcemia) are in the range of 97-98%. This technique may be used in both minimally invasive and bilateral neck exploration techniques. This adjunctive technology can help direct dissection as well as provide information regarding completeness of excision. This will be further discussed in the section regarding radio- guided parathyroid surgery. These factors allow for limited dissection in the area of the diseased gland, decreasing the invasiveness of bilateral neck dissection. Patients with such conditions or non-localizing preoperative imaging should undergo traditional or minimally invasive bilateral neck exploration instead. The incision is carried down to the strap muscles, which are dissected and lateralized. Directed dissection based on preoperative imaging allows identification of the offending gland, while care is taken not to injure the recurrent laryngeal nerve. Since the other parathyroid glands are not visualized in this technique, intraoperative parathyroid hormone monitoring is employed to determine completeness of the operation. If the 50% criterion is not met, explorative dissection to visualize the other glands is employed. Whether general or local anesthesia is used, the majority of Minimally-Invasive Parathyroid Surgery 141 cases can be performed on an outpatient basis. Postoperative calcium levels do not typically have to be checked because the remaining parathyroid glands remain undisturbed. For this same reason, patients do not typically require postoperative supplementation with calcium and vitamin D. Hungry bone syndrome may still occur, however, and inpatient hospitalization and calcium testing should be performed when the concern of postoperative hypocalcemia is high. Contraindications to Focused Exploration Techniques for Parathyroidectomy Benefits of this approach over bilateral neck exploration include shorter operative time, shorter hospitalization, and the avoidance of general anesthesia. Outcomes using this technique are generally comparable to the traditional approach, with relatively high cure (95-99%) and low complication (1-4%) rates. Many studies have confirmed that this is a viable alternative to the traditional bilateral neck exploration. This technique involves intravenous injection of the radiotracer 2 hours prior to surgery. In the operating room, the gamma probe can be used to determine on which side of the neck to place the incision.

Another Spanish poet, Angel Gonzlez, wrote They call you the time to come because you never come, and Tomorrow! If there were ever many lynx, they were hunted for their pelts and their meat; when there were many rabbits, traps and snares were placed to kill the lynx; when the woodland was cleaned it was too clean and used Conserving the Iberian lynx will always be complicated and will require hard work. But we must do it because although today is not as bad as ten years ago, the uncertain tomorrow is still ours.

On the other hand a direct ethanol injury to myocardium will result in cardiomyopathy cheap 20 mcg ipratropium visa, which is discussed in the chapter that deals with heart diseases purchase ipratropium 20 mcg on line. Miscellaneous changes: Chronic alcohol intake has a tendency to produce hypertension even though in low doses alcohol (ethanol) tends to reduce blood pressure buy ipratropium 20mcg with visa. Chronic alcoholics suffer higher incidence of acute & chronic pancreatitis and regressive changes in skeletal muscle referred as alcoholic myopathy. During pregnancy a condition known as fetal alcohol syndrome may 243 take place in infants whose mothers have been taking alcohol even as low as two to three drinks per day. The fetues can have microcephally, mental retardation, facial mal formation & cardiac defects at times. Physical injuries These are mainly classified in to four groups: injuries due to mechanical forces, changes in temperature, changes in atmospheric presence, and electromagnetic energy. A-Injuries due to mechanical forces Injuries due to mechanical forces are (1) soft tissue injuries, (2) bone injuries, (3) head injuries. Here we deal with soft tissue injuries, which are divided accordingly to their depth. Abrasion: this type of injury represents the most superficial type of skin injury, which involves the epidermal layer. It occurs when superficial epidermal cells are turnoff by friction or a glancing blow. There is no perforation of the skin & hence regeneration occurs with out scarring. Laceration versus incision Laceration is an injury over the skin which is an irregular tear produced by overstretching. The margins of a laceration are frequently hemorrhagic & traumatized and there will be bridging stands of tissues like blood vessels or fibrous tissues at the base. The margins are relatively clean and there are no bridging fibrous strands or tissues. An incision, in contrast to laceration, will be approximated by sutures to heal leaving no or little scar. Contusion This is an injury that is cause by a blunt force that injurs small blood vessels & causes intestinal bleeding usually with out a breach on the superficial tissue the bleeding will be evident if the contusion is on a superficial tissue but if it is in deeper structures like skeletal 244 muscles the bleeding will be evident after several hours or may remain obscured excepts the swelling & pain that is felt at the area over the contusion. Gunshot wounds Looking at the gunshot wounds give a very detailed story as to whether the shot is from a distance or, near by, or from a rifle or a handgun. It also tells the direction from which the bullets came & other important information for a forensic pathologist. With a shot from close range, the entry wound has a gray black discoloration produced by the heat, smoke and unburned powder. There are also peripheral stippling of discrete, larger particles formed by the unburned powder, When the shot distance increases a beat only the stippling are present and at greater distances no gray black discoloration or stippling are present rather a wound smaller in size from the bullet and with narrow enclosing rim of abrasion is present. Cutaneous exit wounds are generally more irregular than the entry wounds due to the wobbling or trajectory motion of the bullet. In high velocity riffle bullets the exit wounds are larger and there are no stippling or dark discolorations. Large caliber, light velocity bullets cause extensive injury around the traversing wound due to the mass, velocity and motion of the bullet. Small caliber low velocity bullets cause a limited amount of injury to surrounding tissue. In general, it suffices to say that gun shot wounds tell a story to the experienced individual. B-Injuries related to changes in temperature Human beings are homoeothermic and their internal temperature must be maintained 0 0 between 30 C and 43 C. Abnormally high and low temperatures are injurious to the body and their damage are different and have to be discussed separately. Injuries due to abnormally high temprature These can be brought by flame, boiled water or steam, electricity and etc. Terms like partial thickness and full- thickness burns are applied to describe the degree of burn injury. Epidermis can be fully or partially devitalized and it continues to provide a cover to the burned area. Such burns are characterized by blistering, protinacious fluid exudation from dilated and injured small blood vessels. Inflammatory reaction and regeneration of the epidermis from preserved appendages of dermis are also common features. The epidermal cells may exhibit deranged membrane permeability, with nuclear and cellular swelling or may show clean pyknosis and granular coagulation of cytoplasm. Full thickness burn implies total distraction of the entire epidermis extending into the dermis and even more deeply at times. Regeneration from dermal appendages is scarce and hence healing will result in scarring unless skin grafting is performed. With the epidermis burnt out the dermal collagen may take the appearance of a homogenous gel.
