Slow milk ejection with a long plateau time caused by a tight teat canal 221 Figure 14 antimicrobial jiu jitsu gi buy generic sumycin 500mg line. Figure 11 shows a normal milk flow curve antibiotic 300mg cheap sumycin 250mg overnight delivery, but from a farm where over-milking was applied often antibiotic resistance white house sumycin 500 mg free shipping. Visualisation of the long phase of over-milking must oblige the milkers to change the milking routine and to solve this problem virus on android 250mg sumycin sale, applying the automatic detachment can antibiotics for acne delay your period sumycin 250 mg with mastercard. Milking of the cisternal fraction is shown as the first curve in figure 12 and known as a bimodal curve antibiotics for dogs vs humans sumycin 500 mg discount, which is not frequent in buffaloes, because of the small proportion of the cisternal fraction. Figure 13 is a curve from a buffalo with very low flow rate probably due to a tight teat canal, which is seen frequently in Italian buffalo herds. Most buffaloes need at minimum 8 minutes of milking time, but exceptions can be seen for buffaloes with a high peak flow rate and a short plateau time (Figure 14). Figure 15 showed a milk flow curve with a double profile, due to the partially milk emission disturbed or due to the repositioning of milking cluster. Figure 16 is a milk flow curve of a buffalo not responding to stimulation during teat preparation until oxytocin was injected. The first is classified as failure (no attachment of cluster), the second as incomplete (partially attachment of cluster only two quarters) and the third as complete one, perfectly attachment of cluster (figure 19) (Boselli et al. In figures 20 and 21 milk flow curves at quarter level are shown (Borghese, 2012). Time until a milk flow of 500 g was 195 versus 329 sec in the morning and 224 versus 383 s. Electrical conductivity can be measured simultaneously with the milk flow using the Lactocorder. General udder health and particular teat pathologies may influence milk production in quantity, quality and milk ejection parameters. The general health of animals and good livestock conditions are very important in milk production. Moreover, the milking machine is a very critical factor for the milk flow rates because of the characteristics of milking vacuum, milking pulsation and pulsation frequency, and other technical characteristics connected to the milking equipment (Pazzona, 1989; Dogra et al. Caria et al (2011) compared the effects of milking at low vacuum (36 kPa) and medium vacuum (42 kPa) on milk emission characteristics and milking system performances. The results showed that the low vacuum level did not influence both milk yield and milk ejection time. Milk yield was not influenced by the working vacuum level and resulted satisfactory also at lower levels; the vacuum levels of 37 and 40 kPa showed the best milkability conditions, at which plateau phase was longer than decline phase and lag time was not affected by vacuum level. These results suggest to apply a premilking udder stimulation to reduce milk let-down time increasing the average milk flow and reducing total milking time.

Buffalo milk is characterised by an elevated fat and protein content, both higher than those of cow milk. The total dry matter content of buffalo milk is about 17-19% of which lactose accounts for about 4. Ganguli (1974) reviewed that in buffalo milk fat were found a higher content of butyric, palmitic and stearic acids and a lower content of caproic, caprylic, capric and lauric acids respect to the cow milk. Among the liposoluble compounds it is to underline that buffalo milk does not contain the ficarotene, in fact the buffalo milk fat is colourless, while the vitamin A content is higher than that of cow milk (El Rafey, 1962). The casein index (casein content/protein content %) is higher than that of cow and goat milk (Alais, 1984). Weight of four components in buffalo milk differs from those of bovine casein and respectively, fis1-casein: 30. Then the buffalo casein shows a higher content of fis2-casein and fi-casein than that of bovine casein and vice versa for fis1-casein and fi-casein. From some studies on protein structure of Italian buffalo milk resulted that this species is less polymorphic than the bovine one. This was attributed to either the lack of cross-breeding of Italian animals with foreign water buffaloes, or to the insufficient resolution power of elelectrophoretic methods used for studying the casein polymorphism (Chianese et al. A following study on buffalo milk from Venezuela detected two variants of fi-casein, called A and B, that were different for two amino-acid substitutions. Besides three altered patterns at the level of each fis1 and fis2casein was showed. Further investigations demonstrated that fis1-casein presented ten amino-acid substitutions. The two ficasein variants, A and B presented four and five amino-acid substitutions, respectively (Ferranti et al. Recent investigations on Italian buffalo milk detected a novel fi-lactalbumin variant, that 233 differentiated from one another by a single amino-acid substitution (Chianese et al. Regarding to urea content, the values recorded in buffalo milk are higher than that of dairy cow, as reported in recent studies (Campanile et al. Devendra (1980) reported a content of 0,86%, value that is higher than that of bovine milk, 0. When it is assigned to cheese making it is important to achieve milk which is able to produce high yields and good quality cheese. To evaluate the renneting ability, the lactodynamographic analysis is utilized (Fig. The examined parameters are: clotting time (r), curd firming time (k20), curd firmness at 30 minutes from rennet addition (a30) and A2r (curd firmness at 2r). It is to make allowance that milk with better renneting ability is characterized by a brief clotting and curd firming time and by an elevated curd firmness. The Indian studies reported that the buffalo milk coagulates faster than the cow milk (Puri and Parkash, 1962) hypothesizing as a partial explication the higher susceptibility of buffalo fi-casein to chymosin action. The elevated curd firmness of buffalo milk is probably due to the high casein content of this species milk. In fact addition of the casein to the milk caused a curd firmness increase: an addition of 10% of casein caused an increase of 15% of curd firmness (Amram et al. The casein effect on the curd strength appeared to be more important than the effect of calcium ion increase and pH decrease (Storry and Ford, 1982). It was observed that a part of the individual milk buffalo samples did not coagulate in 30 minutes from rennet addition. The not-coagulate samples were characterized by higher average days in milk, 178 vs 132 d, higher somatic cell count, 385,850 vs 203,260/ml, and higher pH, 6. In a study carried out on 14 623 bulk milk samples from 1996 to 2011, the mean value was 255 147 cells/ml (Giangolini G. Table 1 shows the distribution of mean values for the different buffalo milk component, which showed large variations in the range for the different components (Piccinini et al. Inflammation of the mammary epithelium has the following effects on milk production: reduced milk yield, reduced synthesis of milk components synthesized by tissue cells (fat, casein and lactose), increased passage of blood component to milk (albumin and immunoglobulin) (Anderson and Andrews, 1977; Kitchen, 1981; Verdi et al. From results of recent studies somatic cell count is confirmed to be a valid indicator of udder 3 inflammation in buffalo as in dairy cows. A value of 200 fi 10 cells/ml should be used as the threshold value for early identification of an animal affected by subclinical mastitis. Moreover if chloride content increases, a decrease of milk yield and a worsening of milk composition and coagulating properties resulted. A positive and significant correlation between chloride content and clotting time and negative and significant correlation with curd firmness was found by Giacinti et al. Mean values, standard deviation and ranges for the different milk components in water buffalo quarter milk samples (Piccinini et al. In a study conducted from 1996 to 2012 were analysed 20 036 samples by automatic equipment (Fig. In Italy the price of buffalo milk is not in agreement with fat and protein content and somatic cell and bacterial count, that is generally applied for cow milk, but a poor hygiene of milk could be one of the many factors affecting the shelf life of Mozzarella, which is fresh cheese. During the Mozzarella processing a thermic treatment of curd could be occurred to decrease the bacterial count, but it is not known if the shelf life of the finished product varies according to the number and the type of germs present in the raw milk. Studies in different experimental conditions showed carry over values between 1% and 3% for the cow (Masoero et al. A field study conducted in Latium region (Italy) on 677 samples of buffalo raw milk, showed that the 98. Fat percentage appeared to be influenced mainly by stage of lactation and reached the lowest values in the summer months and the highest in winter; protein percentage was influenced mainly by milk yield and month of the year and reached the lowest values in the summer months and the highest in winter (Pilla and Moioli, 1993). No effect of age at calving and season of calving could be observed on fat and protein concentration (Catillo et al. In fact on Murrah buffaloes milk urea content increased significantly when milk yield increases, decreases with the increasing parity and is negatively related to body weight. Moreover it was observed that milk yield, composition and acidity and lactation stage affected coagulating properties (Matassino et al. Also renneting ability was affected negatively and significantly by higher energetic and protein content of diets. In agreement with these results, Singh and Barsaul (1988) observed a decrease in milk fat when dietary energy increased and Shukla et al. On the contrary, in two investigations on some commercial herds where diets with different energetic levels were administered, respectively, 0. Milk from buffaloes fed with rations with a higher energetic content also had better renneting ability. The different effect of diets were probably due to the different energy/protein ratio and to the genetic potential of the buffaloes used in the trials (Bartocci et al. The short chain fatty acids are mainly present when the energy availability is larger, otherwise, the long chain fatty acids prevail when food energy is smaller. The last condition favours fat mobilization and a higher long chain fatty acids content in blood, then in milk. The addition of whole seeds, as sunflower and flaked soybeans, to standard rations, substantially modified the fatty acids profile. The concentrations of short and medium chain fatty acids decreased 241 while those of long chain fatty acids increased, especially C18:0 and C18:1. The comparison of diets with different protein concentration resulted in a higher milk non protein nitrogen or urea content if dietary protein was higher (Tripaldi et al. In a survey covering some buffalo herds the average milk urea content observed was 40. It was also observed that very low dietary protein can affect urea content and milk freezing point (Campanile et al. In fact the increase of dietary protein level caused an increase in urea content and the stabilization of the milk freezing point (-0.

Next antibiotics to treat cellulitis buy sumycin with a mastercard, they grew these viruses in epithelial cells obtained from kidneys of humans and monkeys (39) virus mutation rate buy sumycin. Subsequently infection board game best sumycin 500mg, the same viruses grown in human kidneys ear infection 8 month old order 250 mg sumycin visa, human amnionic fiuid antibiotic vs antiseptic vs disinfectant generic sumycin 500 mg visa, fertile hen eggs bacteria unicellular or multicellular trusted sumycin 250 mg, and chick embryo cell cultures became the progenitors for the vaccines used today. For recognizing and adapting the culture method of replicating viruses, mainly poliomyelitis virus, Enders, with his colleagues Frederick Robbins and Thomas Weller, received the Nobel Prize in 1954 (30). The safety of cultured and attenuated viruses in producing immunity but not disease was demonstrated first in monkeys. Viruses passed in cultured cells were selected for their diminished ability to harm recipients while still inducing an immune response upon inoculation. When these viruses were inoculated into monkeys intracerebrally (into the brain), no disease or tissue damage occurred. By contrast, monkeys not first immunized developed severe measles virus infections when exposed to the virus. After this success, the attenuated Measles Virus 153 virus was tested in humans, first by inoculating the vaccine into immune adults in whom it was safe. The next step was a bigger clinical trial using children in several American cities. In 1961 Enders and his colleagues reported that measles virus infection could be prevented through vaccination (6). Shortly thereafter, in September 1961, an editorial appeared in the New York Times enthusiastically complimenting Enders on his accomplishment in developing the vaccine for measles and his work leading to the development of the poliomyelitis vaccine (40). For the sake of accuracy, however, I would emphasize the fact that whatever may have been accomplished represents the joint product of many co-workers supported by several institutions. In the studies on measles virus and vaccine, essential contributions were made by Thomas C. To me it seems most desirable that the collaborative character of these investigations should be understood, not solely for personal reasons but because much of all modern medical research is conducted in this way. First, Edmonston and his wife, owing to their personal philosophy, resisted any vaccination of their 154 Viruses, Plagues, and History own children. Second, a favorite toy of children around the globe is called Thomas the Tank Engine. Awdry wrote the story in the 1940s, with publication in 1945, while caring for his son Christopher who was laid up with the measles. Nevertheless, despite the stance of Edmonston and others of like opinion, the widespread vaccination of children in the United States and around the world has dramatically decreased the incidence of measles virus and its sometimes severe complications. A single exposure to the measles virus vaccine results in the production of antimeasles virus antibodies in greater than 80 to 85 percent of susceptible individuals. However, an unsolved problem remaining has been those infants infected with measles virus before their ninth month of age (6). This early infection occurs in a number of countries where the virus continues to circulate widely, particularly in the sub-Saharan African nations. Whether this dilemma will be overcome by immunization of all susceptible children and adults, thereby reducing the circulating virus pool, or design of a new vaccine that can provide protection but avoid neutralization by maternal antibody, remains to be determined. This confiict is currently being hotly debated among experts on measles virus infection (in favor of developing new vaccines that are not neutralized by maternal antibody) and epidemiologists (mainly in favor of using the current vaccine only). The outcome will have an important impact on the goal of possibly eradicating the measles virus. In addition to the large numbers of infants under a year of age who are susceptible to infection, a considerable population of children and adults lack immunity to the measles virus. The virus circulates in a community until its chain of transmission is broken by a massive vaccination program. However, as documented in Gambia from 1967 through 1970, such control is possible. In that small country, a year before the onset of mass vaccinations, 1,248 cases were recorded, but in 1969 and 1970 that number dropped to zero following a series of universal vaccinations done each year. What is clear from such examples is that a commitment by all nations to enforce universal immunization with the current vaccine will clearly reduce or potentially eliminate the presence of circulating virus in virtually every area of the world. Another problem still remaining is the low but significant number of vaccine recipients who fail to respond to the initial inoculation. To counteract this difficulty, many countries have instituted a two-dose schedule, with a second dose given at varying times after the first one. With such a strategy, measles has been eliminated entirely in Finland, Sweden, and Cuba, and the annual number of reported cases in the United States decreased from more than two million per year to now less than a handful. However, this highly contagious virus still travels beyond the borders of countries where vaccination is universal to those where it is not widely practiced, and measles viruses continue to infect those who remain susceptible. In Japan, despite some difficulties experienced with the side effects of a Japanese-manufactured measles virus vaccine, 156 Viruses, Plagues, and History the vast majority of their people have been vaccinated and, until recently, outbreaks of the infection numbered less than a few thousand per year. In Third World countries, measles has been more difficult to eliminate than in developed countries because the contact rates as well as reproduction rates are higher and the infrastructure is less well organized to provide vaccinations. India currently has more measles-related deaths than any other country and yet, at the time of writing this book, has not made measles vaccination a national priority. Even in highly industrialized European countries or the United States, measles has not been eliminated. The causes are inadequate vaccination coverage in preschool-age children, the approximately 5 percent primary vaccine failure rate, apathy, and concern that individuals not government agencies should decide whether to vaccinate. Further, objections that children are receiving too many vaccines and that the measles vaccine is often harmful, even a major cause of autism, although untrue, nevertheless block some vaccinations. Over time, vaccinations to prevent measles sank to 85 percent of the population or below in the United Kingdom in the late 1990s and early 2000s (reviewed in 43,44). As one would predict, soon afterward, outbreaks of measles followed with some devastating aftereffects. Autism, first recognized as a distinct disease in the 1940s, results in children who cannot relate to themselves or to other people and situations. Although its cause was not known in the 1990s and still is not Measles Virus 157 completely understood, the initial reports clearly indicated that autistic children frequently had parents who were highly motivated and career oriented. Further, the incidence of autism increased at the same time that mandatory vaccinations were initiated for infants. According to the paper, of twelve children who had autism and chronic enterocolitis (bowel disease), eight had been given the vaccine and one had a measles virus infection before the onset of autism. No virologic evidence was provided for the measles virus infection, nor was there any stringent epidemiologic evidence to link the infection or other events to autism. First Horton, despite the doubts of his reviewers, published the measles-autism article presumably to increase reader interest in the Lancet. Later, the financial confiicts-of-interest of some authors of the Lancet paper along with questions over lack of informed consent for the children were uncovered and resulted in most, but not all, of the authors retracting the paper six years after its publication. Horton further advocated obtaining financial and confiict-of-interest statements from all authors, which one would consider an absolute condition for any scientific publication. Such synapses are junctions across which neurons communicate, and they are required for sensory perception, movement, coordination, learning, memory, and likely social interaction. Measles, once the scourge of all lands, is now controlled in most countries, although it still kills millions in developing countries. The strategy for elimination of this virus depends on the dedication of every government to do so. The will to save these 500,000-plus lives per year rests solely on the dedication, responsibility, and commitment of the more fortunate nations, of all citizens on this planet, and, in turn, on the politicians and legislatures positioned to set the necessary priorities. Whether measles-related deaths will continue for over 100 years after the development of the measles virus vaccine, as was true for the smallpox vaccine, will largely be determined by the kind of society present in the twenty-first century. At the time of the World Health Assembly declaration of intent in 1988, more than 1,000 people per day developed polio. One hundred and twenty-five countries worldwide reported cases of poliomyelitis, among the oldest and most ferocious of maladies. Eradication of this dread disease was deemed possible due to successful development of the effective vaccines against polio: the inactivated killed vaccine of Salk in 1955 and the oral attenuated live virus vaccine by Sabin in the early 1960s. The United States, and then most other Western countries, discontinued use of the Sabin vaccine in 2000 because no new cases of poliovirus appeared spontaneously (wild-type). However, vaccine-induced polio developed in some geographically scattered individuals whose attenuated poliovirus inocula reverted to a virulent form. The plan was, first, to interrupt wild-type polio transmission and, second, to stop using the oral vaccine three years after elimination of polio. Although the goal of eradication was not met by the year 2000, the approach appeared to be on target. Dramatically, by the year 2003, fewer than 800 cases of poliomyelitis were recorded per year worldwide compared to the over 1,000 cases a day in 1988 when the global initiative program began. In parallel, during 2003 only 6 countries, India, Pakistan, Afghanistan, Egypt, Niger, and Nigeria, reported cases of poliomyelitis in contrast to 125 countries documenting the disease in 1988. A mostly uneducated Muslim population in Nigeria, encouraged by religious and political leaders as well as distrust of the vaccine and the West, spoke against vaccination. Instances of polio increased in northern Nigeria, and the poliovirus likely infected pilgrims going to and returning from Hajj in 2004. By 2005, 264 persons newly infected with poliomyelitis received care, and the epidemic spread initially in countries bordering Nigeria then crossed the Red Sea and moved along the shipping routes to many other areas, predominantly the Muslim country, Indonesia. The use of genetic profiling techniques classified the viruses isolated from the Indonesian patients and several distant countries as identical to the poliovirus circulating in Nigeria. These widespread new cases of poliomyelitis along with an outbreak in Hispaniola in 2002 and another in the United States (Minnesota) in 2005 raised speculation that the elimination of poliomyelitis virus might be impossible. The issues of how polio was first discovered and then controlled, the problems of elimination, and argument for continued vaccination to ensure control constitute the body of this chapter. Employees of the National Foundation for Infantile Paralysis beamed, and thousands upon thousands of volunteers for the lay organization the March of Dimes celebrated a job well done. These volunteers had walked throughout their communities, apartment houses, cinema theaters, and even grocery stores soliciting contributions, and millions of adults and school children had made large and small donations. Not since the Second World War had the fabric of America been woven together more tightly in a single cause. The ringing of the bells was testimony to the announcement that the clinical trial of the polio vaccine showed it to be effective in preventing Poliomyelitis 161 disease. Epidemics in the late nineteenth and early twentieth centuries in Scandinavia, where outstanding clinical investigations and epidemiologic studies by Karl Oskar Medin, Ivor Wickman, Karl Kling, and others took place, led to a lasting commitment by Sweden toward the understanding and treatment of polio. A major epidemic in New York City and surrounding cities during 1916 riveted attention on this disease. Five years later, the man who was to be the thirty-second President of the United States, Franklin Delano Roosevelt, became paralyzed from the waist down after infection with the poliomyelitis virus in midlife. With missionary zeal throughout all parts of the United States, dimes and dollars were raised to alleviate the suffering and tragedy polio infiicted and to wipe out the infectious virus that was responsible. It was one of the rare times, outside of war, in which the citizenry of a nation was united. Unlike other viral diseases that began waning or remained constant in the twentieth century, poliomyelitis was on the increase. In the United States, it blighted lives with ever larger epidemics that peaked in 1952, during which time nearly 58,000 became sick, 21,000 were paralyzed, and over 3,000 died. In 1954, just one year before the pealing of the bells, more than 38,000 individuals were infected (1,2).

Definition: A group of syndromes characterized by increased pressure within a closed anatomical space resulting in local ischemia (limb compartment syndrome) or local and systemic complications (abdominal compartment syndrome). Injury (trauma, hemorrhage, ischemia-reperfusion, venous obstruction) leads to swelling and increased pressure within a compartment. The increased pressure collapses venules, and as hydrostatic pressure increases, eventually collapses arterioles causing limb ischemia. Most common cause is fracture of tibia or distal radius/ulna, in which compartment syndrome has been described in 2-30% of fractures c. Can occur with dilated loops of bowel in absence of trauma, rarely with ascites, peritonitis, pancreatitis. Pressure=Force (fluid volume, cardiac output)/ area (vasodilation) When one part fails, others try to compensate (hopefully). Definition: use of invasive device for continuous, detailed assessment of hemodynamics in order to guide treatment decisions. Trends over time may be helpful, but single values do not predict response to volume load. Exam: generally poor at predicting volume responsiveness and estimating cvp, except maybe the abdomino-jugular reflux Which is a fair estimate of cvp/pcwp. Dynamic measurements: Assess change in hemodynamic variables over time/after physiologic maneuver. Change in Pulse Pressure: Mechanically ventilated patients who are not initiating breaths and have variations in pulse pressure during their respiratory cycle have been shown to respond to volume challenges. Notably, recent evidence suggests that changes in 02 sat waveform may also be a useful to guide treatment (Natalini et al. Conclusion: Little evidence exists for utilizing static measurements to predict beneficial response to volume expansion. Consider empiric antibiotics +/cortisol replacement (hydrocortisone 50100mg every 8 hrs) 80 Major complications: 1. If no response continue resuscitation until core body temp exceeds 95C and then repeat cardioversion. There is some unconvincing evidence that bretyllium is the best anti-arrythmic in this setting. E Ingestions and Toxins Standard approach to all ingestions: 1) Assume there is more than one toxin; however, statistics show that greater than 90% of all accidental and intentional ingestions are only one substance. Give thiamine (100mg) to all patients and before glucose in patients with low blood glucose levels. Gastric lavage should only be performed in patients that present early after ingestion 6) It is still recommended that everyone receive charcoal (1 g/kg). Controversy exists because recommendation is not supported by randomized clinical trial and some opponents say charcoal increases patients risk of aspiration pneumonia. Charcoal may be repeated Q 4-6 hrs, especially for toxins with enterohepatic circulation. It is reasonable to withhold charcoal in patients who present late after ingestion 7) Do a more thorough physical exam to look for classic signs of toxic syndromes. Pupils Pupillary size (normal 3-4 mm in diameter) and reactivity is dependent on sympathetic parasympathetic innervation. Brain stem reflexes, such as the pupillary reaction to light offer clues to the location of the lesion responsible for the coma. If the dilated pupil does not react to light or reacts slowly, it usually indicates a rapidly expanding lesion on the ipsilateral side as in subdural or middle meningeal hemorrhage or brian tumor, that is compressing the midbrain or oculomotor nerve directly or by mass effect. Upper airway has great heat exchanging properties so when thermal injuries occur it is rare from them to damage anything but the upper respiratory tract. Typical problems result from persistent edema causing stridor and superinfection from airway ulceration. However, the low o2 concentration may potentiate the toxicities of carbon monoxide and hydrogen cyanide which compete with the oxygen for the heme molecule. Cyanide binds to iron chelating enzymes such as heme but more importantly cytochrome a-a3. Much later complications: bronchiectasis, tracheal stenosis, bronchiolitis obliterans and pulmonary fibrosis. Deficiency of insulin Induces increased hepatic production of glucose Decreased peripheral utilization of glucose Induces lipolysis whcih generates ketoacids (acetoacetate, Bhydroxybutyrate, and acetone) which causes acidemia 2. Increased counter regulatory hormones Glucagon and catecholamine levels increase inducing glycogen phosphorylase to break down hepatic glycogen stores Growth hormone levels increase which worsen hyperglycemia Cortisol level is increased which stimulates protein catabolism which provides amino acids for gluconeogenesis As a result of the insulin deficiency and increased counter regulatory hormones, there is hyperglycemia. Glucosuria develps because the blood glucose levels exceed the glomerular reabsorptive capacity. Glucosuria induces an osmotic diuresis in which the patient loses 5-7 liters of free water, and electrolytes. Lipolysis as a consequence of insulin deficiency causes the formation of the ketoacids which accumulate and create the anion gap metabolic acidosis. Titrate the insulin drip down a unit per hour as needed to prevent hypoglycemia, but continue it until ketosis is resolved. If the extracellular tonicity is corrected too quickly, there is not sufficient time for the idiogenic osmols to dissipate thus inducing brain swelling. Risk factors for mortality include increasing age and higher levels of serum osmolality. Glucagon and catecholamines induce glycogenolysis in the liver further worsening the hyperglycemia. Proposed mechanism is the development of an osmotic disequilibrium during correction of the hyperosmolar state. If correction of the extracellular hyperosmolality occurs faster than the dissipation of the idiogenic osmols, there is an osmotic gradient favoring brain cell swelling. Arrange formal family meeting for dying patients, in addition to informal updates (Latrette et al Crit care Med 2006) i. Provide information about diagnosis treatments, prognosis in straightforward manner. Summarize-diagnosis, prognosis, plan decided on at end of meeting, next meeting schedule. Stop all interventions will not result in increased comfort (labs, radiographs, frequent vitals, aggressive pulmonary toilet, frequent turning,fi Mechanically ventilated patients may be terminally extubated to humidified air or 02, or terminally weaned to T piece. The method is often attending preference-though terminal extubation is probably preferable allowing for greater interaction between the patient and family. Dying patients experience no increased discomfort after discontinuing artificial hydration or nutrition st d. Morphine is 1 line treatment of pain and dyspnea and should not be withheld for fear of hastening death. J Anaphylaxis Definition: Life-threatening syndrome of sudden onset with one or more of the following manifestations (generally #1+any other is considered anaphylaxis): 1. Constitutional: diaphoresis, pruritis, anxiety Etiology: Anaphylaxis: IgE-mediated immediate hypersensitivity reaction to antigen Anaphylactoid: non-IgE-mediated, but present and are treated the same. Leukocyte reduced products: Leukocytes are the cause of many adverse consequences of blood transfusions. No difference in mortality overall but inhospital mortality higher in liberal group. Subgroup analysis showed less severely ill and age <55 assigned to restrictive group were half as likely to die at 30 days. Authors believe this strategy should be used in all populations, cerebrovascular disease included. In normal host bleeding will only occur when clotting factors fall below 25% of normal. Most rec to correct clotting factors but probably correcting reason for bleed (artery under ulcer base) would suffice. Blood is anticoagulated with citric acid and sodium citrate (citrate binds to calcium). Typically this does not occur because transfused blood is acidotic to serum (pH 7. Hypokalemia is usually transient and is a consequence of transfusion related alkalosis. Defintion: acute onset of hepatic encephalopathy and worsening hepatic synthetic function (eg. Ammonia level >200 strongly associated with herniation, use Lactulose or consider rifamixin g. Fungal infections are underrecognized, 32% of patients in one study (Rolando et al J Hepatology 1991) c. Definition: Stress ulceration is a gastrointestinal mucosal injury related to critical illness. History: Association between critical illness and development of gastrointestinal bleed has been recognized for > 100 years. Pathophysiology of the upper gastrointestinal tract in the critically ill patient: rationale for the therapeutic benefits of acid suppression. Decreased proliferation of mucosal epithelial cells (baseline and in response to injury). Incidence varies depending on severity of illness and type of patient population studied.
