Young Darwin attended the Shrewsbury School, and his early failure to achieve academic distinction continued at Edinburgh University, where he studied medicine, and at Cambridge University, where he studied theology. While at Cambridge, however, Darwin enthusiastically pursued natural history as an avo- cation, drawing the attention of botanist John Stevens Henslow (1796-1861) and geologist Adam Sedgwick (1785-1873). In 1831, through his connection with Henslow, Darwin joined the expedition team aboard the survey ship H.

Free drugs purchase 5 mg proscar with amex man health 1, water-soluble drugs purchase proscar 5 mg on line prostate diagrams anatomy, and unchanged drugs are filtered by the kidneys and eliminated through urine. Protein-bound drugs do not filter through the kidneys until the drug is released from the protein. The quantity of drugs that can be excreted by the kidneys is influenced by the pH of the urine, which normally is between 4. For example, urine can be made more alkaline by giving the patient sodium bicarbonate or made more acidic by giving the patient high doses of vitamin C or ammonium chloride. The results of the creatinine clearance test vary with age and whenever there is decreased muscle mass. In some situations, it is important to reduce the excretion of a drug to prolong the drug’s therapeutic effect, such as with penicillin. Giving the patient another drug, such as Probenecid, blocks excretion of penicillin. Drugs can be excreted artificially through the use of dialysis, which is a com- mon treatment in certain drug overdoses. Drugs that are metabolized by the liver are secreted into bile and then passed through the intestines and eliminated in feces. During this process, the blood- stream might reabsorb fat-soluble drugs and return them to the liver where they are metabolized and eliminated by the kidneys. The lungs eliminate drugs that are intact and not metabolites such as gases and anesthetic drugs. Some drugs, such as ethyl alcohol and paraldehyde, are excreted at multiple sites. A small amount is excreted by the lungs and the rest by the liver and the kidneys. Sweat and salivary glands are not a major route of drug elimination because elimination depends on the diffusion of lipid-soluble drugs through the epithe- lial cells of the glands. However, side effects of drugs, such as rashes and skin reactions, can be seen at these sites. Some intravenously administered drugs are excreted into saliva and cause the patient to taste the drug. Eventually, drugs that are excreted into saliva are swallowed, reabsorbed, and eliminated in urine. Diuretics and barbiturates, which are weak acids, are less concentrated in breast milk. However, even small amounts of drugs can accumulate causing an undesirable effect on an infant receiving breast milk. Some drugs bypass the first pass effect by sublingual administration (under the tongue) or buccal administra- tion (between the gums and the cheek) where they are absorbed directly into the bloodstream from the mouth. These drugs do not enter the stomach where the hydrochloric acid might destroy drug particles. Other drugs go directly to the liver through the portal vein and also bypass the stomach. The drug is then metabo- lized in the liver and much of the drug may be eliminated and not available for a therapeutic effect. Sometimes this effect is so great that none of the drug is available for use if given by mouth. The drug must then be given in very high doses or parenterally (intramuscularly or intravenously) to bypass the liver. Pharmacodynamics Pharmacodynamics is a drug’s effect on the physiology of the cell and the mech- anism that causes the pharmaceutical response. Its secondary effect is to depress the cen- tral nervous system causing drowsiness. The secondary effect is desirable if the patient needs bedrest, but undesirable if the patient is driving a car. A period of time passes after a drug is administered until the pharmaceutical response is realized.

After the interview generic proscar 5mg with visa prostate biopsy results, the individual may be released directly cheap 5mg proscar free shipping androgen hormone 17p, charged and then released, or he or she may be detained to appear before a court. It is at this point that custody moves from the police to other authorities, usually to the prison service. When considering the types of death that can occur during each of these phases, six main groups can be identified based on the reported causes of death. It is clear that different factors may lead directly to or play a major part in the death of an individual while in custody and that different factors will play their part at different phases in the period of custody (see Table 1). Acute alcohol intoxication or the deleterious effects of drugs are, in most cases, likely to have a decreasing effect because they are metabolized or excreted from the individual’s body. Therefore, they are most likely to cause death in the postarrest and early detention phases, and it is important to 332 Shepherd note that their effects will be least visible to those with the “duty of care” while the individual is out of sight, detained within a cell, particularly if he or she is alone within that cell. Similarly, the effects of trauma, whether accidentally or deliberately inflicted, are most likely to become apparent in the early phases of detention, and it would only be on rare occasions that the effects of such trauma would result in fatalities at a later stage, although this has occurred on several occasions, particularly with head injuries (7). Conversely, death resulting from self-inflicted injuries is unlikely to occur in the prearrest and arrest phases of detention but it can and does occur when the individual is placed in a cell and is not under immediate and constant supervision. On the other hand, deaths from natural causes can occur at almost any time during the arrest and detention period. It is possible that the stress (whether emotional, physical, or both) associated with the initial phases of arrest and with the subsequent, more emotionally stressful phases during detention are likely to precipitate the death of the susceptible individuals through the effects of sympathetic stimulation and adrenalin release. Deaths from natural causes should be reduced by the medical examination and supervision of detainees from the time of initial detention and throughout the period of deten- tion (see Chapter 8). However, it is quite clear that the deaths described in many reports are not “pure” (i. Individu- als with heart disease may also be under the influence of alcohol; individuals under the influence of alcohol or drugs may also have suffered trauma, either accidental or deliberate, before or during their detention. In determining the cause of death, it can therefore be extremely difficult to weigh each of the factors that could be identified during the period of detention. There is great need for early assessment and accurate diagnosis of natural disease (physical or psychiatric),alcohol or drug intoxication, and for the identification, docu- mentation, and treatment of all types of trauma. The removal of an individual’s freedom places on the police a duty of care to that individual, and it is only by the active assessment of each and every person entering police custody and the continuing care of that individual that the number of deaths in custody can be reduced. Natural Causes Apart from a few unusual cases, deaths resulting from natural causes while in police custody fall into the groups of disease processes that are com- monly associated with sudden natural death in the community. Cardiovascular Disease The most common cause of death in the community, and of sudden death particularly, is cardiac disease, and within this group, those deaths recorded as resulting from ischemic heart disease or coronary atheroma are the most com- mon. The exact definitions and criteria for the pathological diagnosis of sig- nificant ischemic heart disease (8) are not within the scope of this chapter. Although there is a clear increase in the incidence of this cause of death with age (9), it is important to remember that a small percentage of people in the younger age groups, most commonly those with hypercholesterolemia and hyperlipidemia, may also have significant coronary artery disease, and because the younger age groups are more likely to be arrested by the police, these few individuals may assume great significance. The significance of coronary atheroma is that individuals with this dis- ease are particularly prone to the development of dysrhythmias during periods of stress when their decreased ability to perfuse areas of the myocardium may result in the development of ectopic electrical foci. Deaths may be preceded by the development of classical cardiac chest pain, or it may present with sudden collapse and death without warning. Individuals suffering from significant myocardial hypertrophy resulting from chronic hypertension are also at greater risk during periods of stress. Once again, it is the older age groups that are most commonly affected by essential hypertension, which may also render these individuals susceptible to focal lack of myocardial perfusion during periods of tachycardia. In addition to these two disease processes, there are also rarer diseases or syndromes that may cause sudden death, which are possibly more significant in the context of “deaths in custody” because some of them tend to affect younger age groups in particular. Current research is now focusing on a genetic basis for many other sud- den cardiac deaths in the younger age groups. The examination for these specific gene markers in any sudden death in police custody must now be considered in the absence of other causes of death. Other cardiovascular causes of sudden death, for the most part, are also age related. The rupture of atheromatous aortic aneurysms is a disease almost entirely confined to late-middle and old age, whereas the rarer forms of aorti- tis and collagen diseases of the aorta (11), which may also result in rupture, are more commonly seen in the younger age groups. It is most unusual for deep venous thrombosis of the leg veins to be present in a young active male; however, the association between some types of the combined oral contraceptive pill and the development of thromboses has been known for some time (12) and may render a small sub- group of the female population at greater risk of pulmonary emboli than the general population.
