Although those raised on a high salt diet showed an elevated preference for sodium chloride solutions, males also showed a preference for glucose solutions. The weights of adrenal glands of the males in the highest salt group were significantly lower than controls. Borderline hypertensive rats fed a diet containing 8% sodium chloride from conception to weaning: offspring demonstrated higher blood pressure as adults (Hunt and Tucker, 1993). Cardiovascular health and blood pressure There is a large body of data on rodent models which indicate that depending on genetic strain there may be different degrees of sensitivity to dietary sodium. The immediate relevance of this work for long term human health is not clear (Swales, 1994). Perhaps the most informative intervention study of relevance to human physiology is that conducted by Denton et al (1995) on the effect of increased levels of sodium chloride on the blood pressure of chimpanzees. A colony of 26 chimpanzees, aged 5 to 18 years, was maintained on a vegetable and fruit 433. Sodium chloride in the range habitually consumed by human populations was added to the diet of one half of the animals over a period of 20 months. The stepwise addition of sodium chloride caused a highly significant, stepwise rise in systolic and diastolic blood pressure. The increase in blood pressure reversed completely following the cessation of the added sodium chloride to the diet. The effect was variable amongst different animals, with some having a larger and others a smaller or no rise in blood pressure. There may be direct or secondary systemic metabolic perturbations in fluid and acid base balance. There is neurological dysfunction leading to seizures and damage to the central nervous system, muscle dysfunction and renal damage. Carcinogenicity the evidence for an effect of NaCl on the incidence of cancer is less clear in humans than in experimental animals. Salt consumption has been associated with cancer of the naso pharynx and cancer of the stomach. An increased risk of cancer of the larynx, mouth and pharynx has been associated with consumption of salt-preserved meat and fish (Zheng et al, 1992; Anderson et al, 1978). Eight case control studies of people from China living in different parts of the world found statistically significant increases in risk for nasopharyngeal cancer, with odds ratio varying from 2. Experimental studies in rats and hamsters corroborate the findings, and consideration of aetiological factors indicates that volatile carcinogenic nitrosamines might be particularly important. In areas where mortality from nasopharyngeal carcinoma was particularly high, there were highly significant correlations with total volatile nitrosamines in salted fish samples. There is some evidence to suggest a possible interaction with Epstein-Barr virus, which appears to be activated by the chemicals found in salted fish (Ho et al, 1976; Shao et al, 1988). Throughout the world, a strong and consistent relationship has been found between the intake of salt and salted foods and the incidence of cancer and pre-cancerous lesions of the stomach. Biological pathways by which salt increases cancer of the stomach are best explained by salt in the diet acting to damage the protective mucosal layer of the stomach, thereby enhancing carcinogenesis.

Platelet-rich plasma must be separated from whole blood by centrifugation within 8 hours of phlebotomy. Additional centrifugation and removal of most of the supernatant plasma may then concentrate the platelets. This is essential to prevent platelet aggregation which results in loss of viability. The shelf life and transport conditions differ according to the type of plastic bag used to store the component. If no platelet agitator or rotator is available, it is not possible to store platelets. Since platelet concentrates are stored at room temperature, they pose a greater risk for bacterial proliferation. If they are kept at room temperature, attach a sheet of paper and a thermometer as close to the agitator as possible. Record the temperature at least four times a day, and check whether it is maintained within the acceptable range. They are used to treat patients with specic protein deciencies or requirements for passive immunity. In some countries, plasma derivatives fall under the responsibility of the pharmacy unit of the Ministry of Health. Manufacturers of laboratory reagents recommend methods for their safe storage and transportation. The recommenda tions in the package inserts must be followed to avoid deterioration of the reagents and subsequent poor performance in use. The method of collection, storage and transportation of blood samples will depend on the type of laboratory test to be carried out.

The tuning fork is activated and held near the meatus, conducting sound through air. Then the fork is applied frmly to the mastoid region, conducting sound through bone. The patient is asked to indicate if air conduction (tuning fork near meatus) or bone conduction (tuning fork applied to mastoid) is louder. A patient with a normal-hearing ear will indicate the signal from air conduction is greater than bone conduction (termed a positive Rinne). If a tuning fork is not available and the patient is cooperative, ask the patient to hum strongly for several seconds and identify in which ear the sound seems more intense. The audiogram should be repeated prior to ossiculoplasty or tympanoplasty surgery to determine residual hearing loss. The otic capsule is very dense, and fractures involving the otic capsule are 148 resident Manual of trauma to the Face, head, and Neck uncommon. Neurologic injuries include concussion and injuries to the brainstem and vestibular/cerebellar pathways, and may co-exist with inner ear injuries. The evaluation of a patient with dizziness should include a detailed neurologic evaluation and a bedside vestibular evaluation. Further testing with audiogram and vestibular function tests is useful, but are usually obtained when the patient can be tested in the ofce setting with appropriate equipment In trauma patients, a cervical spine injury should be ruled out before performing the vestibular evaluation. A fracture of the otic capsule generally results in a severe vestibular injury, but injuries can occur in the absence of a fracture. The narrowest portion of the canal is the meatal foramen, through which the labyrinthine portion passes, and is thought to be a frequent site of compression injury. The most impor tant point is the perigeniculate region, where the nerve is tethered by the genu and the greater superfcial petrosal branch. This complex anatomy and narrow bony pathway make the facial nerve highly susceptible to injury in temporal bone fractures.

Pressure changes and resistance Pressure Changes Affect Lung Volumes In a normal lung, air flows in and out when a pressure gradient is created. During inspiration, expansion of the thorax causes the intrapleural and alveolar pressures to decrease, gas flows into the lung. During exhalation passive recoil of the lung causes the intrapleural pressure and alveolar pressure to increase; gas flows out of the lung. Note that during inspiration and exhalation the pleural pressure is always less than the pressure in the alveoli. The transpulmonary pressure (Fig 1) also increases and decreases with lung volume. At the end of an unforced exhalation when no air is flowing, then the following conditions exist: alveolar pressure = 0 mmHg intrapleural pressure. When there is no airflow in or out of the lungs, the transpulmonary pressure and intrapleural pressure are equal in magnitude but opposite in sign (Fig 1). In ventilation, air flow is determined by the difference between atmospheric and alveolar pressures.

In 2009, Moers et al reported the results of a well-designed adequately powered European multicentre randomised controlled study in which one kidney from a donor was assigned to machine perfusion using the LifePort machine (n=359) with the contra-lateral organ assigned to cold storage (n=359) [276]. Trained perfusionists were used to transport and set up the machine perfusion device at the donor hospital. The size of the treatment effect was no different after standard-criteria donation versus expanded-criteria donation. Because it was considered that an insufficient number of non-heartbeating donors had been enrolled after initial recruitment for subgroup analysis (heartbeating versus non heartbeating donors), the investigators extended the study until a total of 82 non-heartbeating kidney pairs had been randomised. In neither the main data set nor the extended data set was a significant difference observed in delayed graft function between machine perfusion and cold storage in kidneys coming from heart beating versus non-heartbeating donors. However, the same group published a subgroup analysis of outcome in the 82 non-heartbeating kidney pairs from the extended data set of the Machine Preservation Trial [277]. In contrast, Watson et al published also in 2010 the results of a multicentre randomised controlled trial of machine perfusion versus cold storage in non-heartbeating donor kidneys only using a sequential study design which stops patient recruitment after there is sufficient evidence to reject the null hypothesis [278]. After 90 transplants from 45 donor pairs, there was no difference in the incidence of delayed graft function or in any secondary endpoints. Trained perfusionists were not available and when kidney retrieval occurred away from the base transplant centre, kidneys randomised to machine perfusion could first undergo a period of cold storage during transport to the base hospital. Given these conflicting results and in the absence of a pharmaco-economic evaluation of the cost of employing dedicated trained perfusionists as part of the retrieval team, no firm recommendation can be made regarding the optimum method of organ preservation until more evidence emerges from further studies. Suggestions for future research Further adequately powered randomized studies are required of machine perfusion vs. Ideally, these studies should be international and multicentre, to 92 allow generalizability, and include a pharmaco-economic evaluation. Also, accepting only a short cold ischemia time might lead to loss of otherwise acceptable grafts. However, for every 94 additional hour of ischaemia time over 21 hours, the risk of transplant failure increased by 4% [280]. Cold ischaemia time is associated with delayed graft function, defined as the need for dialysis in the first week after transplantation. Similarly, the detrimental effect of delayed graft function on graft survival was explained by an increased incidence of acute rejection [285]. Cold ischaemia time is an important modifiable risk factor that can influence outcome. Based on observational studies, we recommend that when transplanting kidneys after controlled circulatory death (Maastricht category 3) cold ischaemia time is kept below 12 hours. No other guideline body provides any indication on which maximal cold ischemia time is acceptable. Impact of cold ischemia time on renal allograft outcome using kidneys from young donors.
