This is different from the delusion of mind reading wherein the patient believes others can read their mind/thoughts 60 pills abana mastercard, i buy abana 60pills on line. Telepathy refers to the deliberate beaming of thoughts from one person to another buy generic abana 60 pills line. If the temporal lobe is stimulated during surgery, patients may experience similar ‘made’ thoughts and feelings as are found in both the temporal lobe epileptic aura and in the psychoses. Delusions of Passivity: one is forced by outsiders to experience bodily sensations. Delusional perception is present when a delusional interpretation of a real perception is made; the perception is mundane and logically unconnected, e. The term delusional mood (or atmosphere; Wahnstimmung) refers to the state of perplexity (usually unpleasant emotional state akin to bewilderment), foreboding, dread or anxiety occurring early during a psychotic breakdown, consisting of a variety of paranoid delusions which are transient and changing; the patient tries to make sense out of what seem to be 150 unusual changes going on about him; he may recover or develop a stable delusional system. During the early formative or recovery stages of a delusion we can speak of a partial delusion, when the belief is held with less intensity. Delusional memory (retrospective delusion) refers to a delusional interpretation of an 151 apparently real memory or a false memory arising in the context of psychosis, e. Somatization can be a primary personality trait, or secondary and transient when under stress or depressed. Alexithymia, or alternatively somatothymic,(Yates ea, 1998) refers to a constricted ability to recognise and express feelings or emotional states. Alexithymia may be mimicked by certain cultural expression styles and may be a state- dependent phenomenon, e. A dominant individual within a tight social grouping usually starts epidemic hysteria. Treatment involves quick recognition, isolation of affected individuals, psychological explanation and reassurance, use of local traditional healing methods (Skuse, 2007), and the delivery of mental health education programmes to the community. Insight: Poor insight in psychiatric patients is associated with non-compliance, social dysfunction, and delayed presentation. Insight into psychiatric disorder is not a uniform phenomenon; and it must be rated on a continuous rather than a dichotomous scale. Rather than saying that insight is present or absent, we should ask if the patient knows that he is acting abnormally, thinking abnormally, or experiencing abnormal 152 Also called Blocq’s syndrome after Paul-Oscar Blocq (1860-96). Sophisticated testing suggests that very few acute voluntarily admitted patients can understand the need for neuroleptic drugs. Reduced general neuropsychological functioning and grey matter deficits in the posterior cingulate gyrus and right precuneus/cuneus may be important in lack of insight in first-onset psychosis. The Insight Scale (Marková & Berrios, 1992b) is 32-item instrument, can be observer- or patient –rated and purports to measure insight and changes therein. There are many examples of cases where the patient is hallucinated but retains insight. Partial seizures can be associated with visual, auditory, olfactory, or gustatory hallucinations with retention of insight. The same applies to olfactory hallucinations due to migraine or, rarely, damage to the olfactory bulb/nerve. Similarly, auditory hallucinations due to pentoxyfylline, deafness (with musical hallucinations – see Miller & Crosby, 1979), and lesions of temporal lobe or pons, can be accompanied by retention of insight. Visual hallucinations can occur during bereavement (visions of a lost one), because of sleep loss, or when falling asleep. Visual hallucinations with insight may also be found with migraine, narcolepsy (hypnagogic), Charles Bonnet syndrome,(Q. For the patient in psychotherapy, self-observation is insufficient for true insight. What is needed if real 157 change is to occur is emotional , as distinct from intellectual, insight. Quality of life Quality of life is a difficult concept to define and attempts at measuring it have varied from generic (independent of specific disease) to disease-specific instruments. One can measure health intervention outcomes in terms of quality (score 1 for perfect health, 0 for no quality, minus scores for ‘better off dead’) and quantity (life expectancy) of life. Quality and quantity are 154 The majority of patients with schizophrenia in one study (Amador ea, 1994) were unaware of important aspects of their illness and almost one quarter were almost completely unaware of the efficacy of treatment. Those with affective disorders had less severe lack of awareness, although manics more closely resembled schizophrenics in this regard. Schizophrenic patients in remission were just as unaware as were those who remained psychotic. On the other hand, David ea (1992) found that compliance only weakly related to ability to label psychotic phenomena as abnormal. Murray (2003) points out that delusional beliefs developed during a period of psychosis may persist despite clinical improvement, e. David ea (1992) could find little relationship between insight and age, sex, diagnosis or number of hospital admissions.

However 60 pills abana free shipping, they may also be found in schizophrenia purchase 60pills abana free shipping, severe affective disorder abana 60pills otc, following torture (Rasmussen, 1990) and, in 12% of cases in one series, in ‘hysteria’, (Perley & Guze, 1962) which today would be called dissociative disorder. Anticholinergic drugs may be associated with visions of bugs crawling on the skin. Gustatory (taste) hallucinations should not be confused with the various tastes produced by drugs. Pseudohallucinations, an imprecise and controversial term that would be better discarded according to some authors,(Taylor, 1981) involve the reporting of hallucination-like experiences but without an identifiable percept: he may saw he sees things that are not there but is unable to describe an actual specific perception; they are less vivid and realistic than hallucinations, are often located inside the head (internal 104 space), and often coincide with true hallucinations. It should be remembered that visual hallucinations due to disease of the central pathways of the visual apparatus are 105 rare. Hypnagogic (going to sleep ) and hypnopompic hallucinations (on waking) occur when the level of consciousness is between waking and sleep, and they are often normal. Lilliputian or microptic hallucination Bright, funny, everything is much reduced in size Aetiology: Alcohol Anaesthetics Enteric fever Scarlatina Delirium tremens - small, obscene and abusive creatures (Sims, 2003, p. Epstein-Barr virus) and lesions of the non-dominant parietal area A reflex hallucination occurs when one sensory modality is excited and the cause is irritation in another, e. A functional hallucination is provoked by a stimulus and occurs in the same sensory modality as the stimulus; both the stimulus and hallucination are perceived at the same time and are also perceived as being distinct. A classical example would be when a person turns on a tap and only hears a hallucinatory voice whilst the water is running, but he also hears the water running. Auditory hallucinations, like those in other sensory spheres, need not be well formed. Auditory hallucinations are commonest in schizophrenia and in alcoholic hallucinosis. In alcoholic hallucinosis the voices respond poorly to neuroleptics but they clear if the patient remains abstinent. Normal people may hear noises or voices when dropping off to sleep, on waking, when tired, when exposed to extreme sensory or social isolation, or at the height of a bereavement - the voice may simply call the person by name, e. Extracampine hallucinations are visual hallucinations seen outside the field of vision, such as behind oneself, or auditory hallucinations reported to be heard from outside the range of unaided hearing (e. The may occur in normal people as a hypnagogic phenomenon , in schizophrenia, or in organic disorders including epilepsy. Metamorphosia means that objects appear irregular in shape when in fact they are not; retinal scars can cause this or macropsia whereas an oedematous retina can be associated with micropsia. Porropsia means that objects may seem to retreat into the distance (overlap with micropsia). A rare complication is the Doppelganger phenomenon where the person also believes that they have a double. Perhaps because of non-recognition of family, a person may believe that other people live in his/her house: phantom boarder syndrome. Prosopagnosia in its severest form may include failure to recognise ones reflection in the mirror. However, this is most commonly found in dementia with its more global manifestations. Rarely, a patient may look in the mirror and decide that the reflection represents an untrue version of the self (shades of Capgras, although the patient may simply be unsure of the facts). Shakespeare’s Caliban, an outcast in the Tempest, appears to have had this syndrome. The dominant hemisphere then views this activity as alien to the self because of a primary dissociation in the functioning of the two cerebral hemispheres in schizophrenia. Hallucinations may be seen as an expression of brain activity or as products of adaptive behaviour, as when seeking organisation in a chaotic array or motivated by dynamic imperatives. In particular, thought-disordered content could be superimposed on either primary or compensatory brain-based phenomena. During simultaneous occurrence of hallucinations and external stimuli, hallucinations were reported to lower N100 amplitudes and changed topography, suggesting competition between auditory stimuli and hallucinations for physiological resources in the primary auditory cortex; auditory hallucinations may therefore be a consequence of abnormal primary cortex activation. Interestingly, subvocalising during reading decreases reading speed but improves comprehension. Bick and Kinsbourne (1987) found that schizophrenic patients reported that the voices they heard went away when they kept their mouths open, so precluding subvocalisation, but not when they merely clenched their fists. Nevertheless, most patients with schizophrenia can make clear distinctions between auditory verbal hallucinations (‘voices’) 123 and their everyday thoughts. Definitions Lability of affect: variably defined as excessive emotional responsivity or unpredictable changes in affect, such as when the happy person suddenly becomes angry, only to sink into despair a short time later (e. Winston Churchill told his doctor on July 3, 1953 that ‘Since this (stroke) happened I have been very lachrymose. At parts of Phineas Finn I became very tearful, though it is not at all a moving story’. In schizophrenia, the emotional reaction may initially be congruous but then not change with altered circumstances, so-called stiffening of affect. The patient with abulia has no impulse to action, his mind is blank and empty, and volition is absent. However, it has also been described in association with damage to the 123 They do this by examining mainly thought content and sense of control, whereas loudness and clarity are of lesser use.

Certain antibiotics have time dependent killing buy 60pills abana with mastercard, and others have peak concentration dependent killing cheap 60 pills abana fast delivery. Antibiotics with time-dependent killing: Glycopeptides and beta lactams have time dependent effects 60 pills abana sale. This is achieved by x administering the antibiotic by continuous infusion or more frequent dosing x using a drug with a long half life x co-administration of another drug which blocks the elimination of the antibiotic Severe infection 53 Handbook of Critical Care Medicine Antibiotics with peak concentration dependent killing: Aminoglycosides and fluoroquinoloes have this property. The drug should be administered at high doses to achieve high peak concentrations, with longer intervals between doses to prevent toxicity. In general, it is defined as systolic blood pressure less than 90 mmHg or mean blood pressure below 60 mmHg. Also, patients who are hypertensive may have symptoms of hypotension when their pressure falls. Because of this, a drop in systolic blood pressure more than 40-50 mmHg from baseline is also considered hypotension. Ask the patient, relatives; check previous records, physician’s notes x Is the patient on antihypertensive medications? Sometimes, features of organ hypoperfusion may present, such as anginal chest pain, hypoxia, or altered level of consciousness. Always think of unusual but obvious causes of hypotension: consider the following case-vignette: A 60 year old man presented to an outpatient clinic with a history of feeling faintish for a few hours. He was resuscitated with fluids and blood, and was later found to have a hepatoma, with haematobilia. Hypotension 55 Handbook of Critical Care Medicine Differentiate between hypotension and shock Hypotension can occur without shock. Shock is a serious condition, with ongoing tissue hypoperfusion and tissue dysfunction and, most of the time, metabolic acidosis caused by anaerobic tissue metabolism with lactic acid production. Can also be caused by certain antihypertensives x Idiopathic low blood pressure can be seen in some healthy individuals. Patients with dengue infection can manifest with low blood pressures without tissue hypoperfusion, although such patients could develop shock and should be watched carefully. Organ dysfunction has not set in yet, and at this point fluid resuscitation alone will normalise the blood pressure and prevent the development of septic shock. Hypotension 56 Handbook of Critical Care Medicine Conversely, shock may be present with an apparently normal blood pressure. Anaphylaxis could present with sudden hypotension Examine for x Features of shock (see above) x Features to differentiate hypovolaemic, cardiogenic and vasodilatory shock x Possible correctable causes of shock- pneumothorax, pericardial effusion Causes of hypotension and shock All hypotension and shock falls in to one (or a combination) of the following x Shock due to reduced ventricular filling - Hypovolaemic shock x Shock due to reduced cardiac contractility - Cardiogenic shock x Shock due to a decrease in systemic vascular resistance - Vasodilatory shock The different conditions which result in each of these types of shock are shown in the table. Relative intravascular fluid depletion can occur when the vascular tone is decreased, resulting in increased capacitance and low peripheral vascular resistance (sepsis, anaphylaxis). Often, in a given patient with shock, more than one type of shock could be present. For example, a patient with vasodilatory septic shock and severe Hypotension 57 Handbook of Critical Care Medicine acidosis will have a cardiogenic component contributing to low blood pressure, and in addition will have relative intravascular hypovolaemia. Clinical differentiation of the types of shock The history may suggest the cause of hypotension. If obvious bleeding or other cause of hypovolaemic shock is present, the diagnosis will be obvious. A history of ischaemic or valvular heart disease, together with an anginal chest pain may suggest cardiogenic shock. The pulse volume will be low, with peripheral vasoconstriction and activation of the sympathetic system resulting in sweaty peripheries; hence, the classical cold, clammy extremities with a weak, thready pulse. Marked pallor may suggest bleeding to be the cause, although in both cardiogenic and hypovolaemic shock, peripheral vasoconstriction can result in pallor. In contrast, good volume, ‘bounding’ pulses are seen in vasodilatory shock (characteristically septic shock), with a wide pulse pressure, and warm extremities. The presence of a gallop rhythm, plus or minus murmurs may suggest cardiogenic shock. The brain is the organ which is most susceptible to ischaemia and hypoxia, and hypoxic brain damage is irreversible. The kidneys are also very vulnerable, and nearly all organs and tissues in the body will be affected with prolonged hypotension. Once ischaemic tissue damage becomes established, reversal of shock does not significantly improve outcome. In early studies, it was found that reverting the blood pressure to normal by using fluids, inotropic agents and blood transfusions did not improve survival in patients who had developed multiorgan failure following prolonged tissue hypoperfusion. However, early restoration of tissue perfusion, with aggressive fluid resuscitation, before tissue damage has taken place, prevents multi-organ failure and improves outcome.

However abana 60 pills on line, the existence of punish- ment after birth might act as a deterrent against harmful behaviours earlier in pregnancy 60pills abana amex, and thus it joins the array of threats available to society to inXuence behaviour cheap abana 60pills with mastercard. Bewley Moral ranking of different strategies The order of preference of strategies to inXuence behaviour is: (1) oVers (or incentives) over threats; (2) non-coercive means over coercive means; with (3) physical force and punishment being the least preferable. They need not be mutually exclusive (though some are, such as the promise of medical conWdentiality and the revealing of urine sample results to the police). It is permissible to use oVers and non-coercive threats when women can stop harmful behaviour (although threats need extra justiWcation over oVer), whereas coercion is only permissible, if at all, when women cannot stop freely. The will of a drug-taker Frankfurt’s account of freedom reXects well the complexity of autonomy, and presents a way to unravel the drug addict’s intent. He describes what distin- guishes us as human beings as our ‘ability to form second-order desires’ (Frankfurt, 1971) – only human beings can want to want something. Al- though a woman might have conXicting Wrst-order wants, it is the identiWca- tion with a second-order desire that determines the kind of person she is. Her Wrst-order desire to take drugs over- whelms another Wrst-order desire to do the best for her fetus, and possibly a second-order desire to be a drug-free woman. Real life may be more complicated, as the Wrst- and second-order desires of an addict might change throughout the day, as the cravings wax and wane, or through- out the pregnancy, as the fetus grows and interacts. M1 may stop taking drugs either because she is mindful of her duty and does not wish to harm her baby, or because she is reluctantly goaded into stopping. When a mother wishes to do the best for her baby, the result Restricting the freedom of pregnant women 141 of this oVer corresponds to one part of her will and her interests. The existence of a future punishment is in itself a present threat, but if it is in society’s armamentar- ium, it acts as a threat to all pregnant women. A drug addict who reacts to falling levels or shortage of supply with feelings of severe discomfort (withdrawal syndrome) has no choice but to respond with the reasonable and purposive action of buying or Wnding more drugs. The only way to stop her taking drugs is by force, for example, by incarceration to (hopefully) cut oV her supply of drugs, an external coercion corresponding to the inner compulsion to take drugs. Some soft cheeses contain the listeriosis bacterium, which can cause miscarriage, fatal intra-uterine infections and premature labour (with all its consequent com- plications). If eating soft blue cheese and taking heroin had the same adverse eVects on fetuses, but an addict’s discomfort on stopping heroin was marked- ly worse, then the mother who continues to eat gorgonzola would be more culpable than the woman who continues to take heroin. To avoid suVering severe discomfort, by withdrawal of the drug M2 craves and is compelled to take, the rational and reasonable action is to avoid giving a sample of urine, or miss the clinic. Antenatal care, even in the presence of drug-taking, is of beneWt for picking up other diseases of pregnancy, such as diabetes, pre-eclampsia and growth retardation, and it 142 S. Indeed, the policy of British antenatal care and drug maintenance programmes is to stabilize registered addicts on drugs prescribed by licensed doctors. If the woman attends the antenatal clinic at the same time, two potential improvements to her baby’s health are made even before drug reduction (De Swiet, 1989). The complexity of judging and influencing maternal behaviour With this complex model in mind, the drug-taking pregnancy can be viewed not merely as a grave danger to the fetus due to maternal failing, but as an opportunity to oVer intervention and improve fetal health. The pregnant drug addict may be harmed, or even die, as a consequence of her drug-taking, and thus the incentive to improve her own health may be added to fetal incentives. If her will is in conXict, as described earlier, she has the opportunity to identify more strongly with that part that wishes to do the best for her fetus, or wishes not to be a drug addict, and thus become more truly an autonomous person. If, without drug treatment programmes for pregnant women (Chavkin, 1990), she misses this opportunity, society fails both to aid her fetus and to help her realize her autonomy and potential. Strategies that threaten her, or that through fear or interaction with her compulsion diminish rational and reXective self-evaluation, reduce her autonomy (already reduced by addiction). Other incentives that might encourage M2 to minimize harm to her fetus, such as public education, free and conWdential health care, non-judgemental attitudes and access to social service help, will get drug-takers into clinics. Widening the scope Several more qualiWcations still have to be considered before limiting preg- nant women’s freedom: (1) there should be a real and serious risk to a particular fetus; (2) as a woman’s freedom is increasingly interfered with, so the justiWcation for the limitation should become stronger; (3) there has to be no less drastic method for achieving the same end; (4) the harm prevented should not be less than any harm caused; and (5) if freedom is limited, women are harmed by interference with their basic right of liberty (albeit justiWably, and thus not wronged) and there is a case for compensation. If the risk is very remote – for example, every millionth pregnant woman walking on icy pavements falls over and suVers a stillbirth – that would not seem to justify keeping pregnant women indoors all winter. If the risk is of trivial harm – let us say that listening to commercial radio made babies respond by smiling to advertising jingles – that would not justify banning pregnant women from listening to the radio. Increasing restrictions on liberty, increasing justification An example of justiWable limitation on freedom might be long-distance air travel close to delivery. It seems reasonable to balance the small risk of premature delivery and a great limitation on freedom if women could not travel at all against a higher chance at term and less limitation on freedom. Bewley (embryo-deforming) poison gas dioxin blowing towards a city, a justiWcation of forcibly rounding up the pregnant women to transport them away could be based on avoiding harm to their fetuses. If preventing fetal harm overrides women’s rights to freedom, or bodily integrity, it can also be used to override their wishes regarding the continuing of the pregnancy. The arguments can boomerang back to argue for enforced abortions (if abortion is justiWed as the killing of a being without full moral status), when an abortion is a lesser wrong than allowing the continuance of a pregnancy that will lead to a life of suVering. Only the most draconian measures (such as screening the entire female population for pregnancy) would be able to identify those women whose behaviour in early pregnancy is an avoidable source of harm.

Sphenoidal electrodes (less often used today than heretofore) record discharges from the temporal lobes purchase 60pills abana fast delivery. Nasopharyngeal leads are not thought to add much to scalp recordings and can be very uncomfortable discount 60 pills abana amex. Although electrodes F7 and F8 are known as anterior temporal leads they lie over frontal areas; nevertheless cheap 60pills abana visa, they reflect mostly anterior temporal lobe activity. More accurately, anterior temporal activity can be recorded by tracing a line between the external meatus and lateral canthus and putting the electrode one cm above a spot one third of the distance forward from the meatus. During surgery it becomes possible to record directly from the surface of the brain, so-called electrocorticography. They can be synchronous or asynchronous, depending on whether they appear in corresponding leads. Even the localisation of an abnormal electrical discharge is not a universal indicator of lesion site. Hill (1952) found that psychopaths (especially those with a history of impulsive homicide) had evidence of ‘delayed’ cerebral maturation (bilateral rhythmic theta activity in central and temporal regions, alpha variants, and episodic posterior temporal slow-wave foci). The finding of slow waves should not be too readily passed of as indicative of ‘electrical immaturity’. The testing condition 346 that has most consistently revealed hypofrontality (prefrontal cortical hypofunction) in schizophrenia is the Wisconsin Card Sorting Test. This, they suggested, might reflect dysfunction of the recurrent inhibitory drive on auditory neural networks. Numbers are an average of the time in milliseconds passed 349 between stimulation and appearance of a component, e. The P300 latency is prolonged in depression and reflects 350 a diminished ability to attend, which in turn may be dependent on serotonin. The P50 is thought to index early gating of incoming sensory data (abnormal in most, but not all, schizophrenic subjects; also abnormal in their clinically healthy relatives; linked to polymorphism in alpha-7 nicotinic receptor). Researchers have looked at P50 abnormalities as a potential endophenotype for schizophrenia. When 2 clicks separated by 200 msec are presented the patient the amplitude of the P50 wave following the second click should be smaller than that after the first click. In some cases of schizophrenia both waves are of equal amplitude, indicating a possible failure of sensory gating. To some degree this abnormality may be related to polymorphisms in or near the alpha-7 nicotinic receptor subunit gene (chromosome 15). Some panic attacks occur at night, especially during the transition between stages 2 and 3 when dreaming is absent and cognitions are minimal. Most people have a number of brief awakenings during sleep but may not recognise them as such unless they persist for more than a couple of minutes. Humans tend to take all the day’s sleep in one go (100% consolidation) whereas guinea pigs sllep in short bouts spread throughout the 24-hour period. The sleep cycle does not lengthen until adolescence, when the 90-minute cycle of the mature adult is achieved. K-complexes are said to resemble the letter K: high amplitude biphasic waves, the first component being negative. K-complexes can be invoked during light sleep by ambient noise and may represent efferent cortical signals that travel to thalamus and brain stem. The spindles are complexes of increasing and then decreasing amplitude (12-14 Hz). Ejaculation occurs in response to dreams of a sexual content but the erection as such is content neutral. Therefore they experience a phase shift advance, the normal circadian rhythm having been brought forward in time. After a few sleepless nights a person becomes confused, incoherent and irrational. Interestingly, combining fluoxetine with the hypnotic drug eszopiclone was associated with greater improvement in depression scores than when fluoxetine was given alone, and such improvement was not explained by better scores on sleep items within the depression scales. The nadir (lowest point) of body temperature occurs in the second half of sleep; maximum body temperture occurs in the afternoon. Cortisol is produced in bursts throughout the night, reaching a daily maximum at c. For example, Allen ea (1991) failed to find a significant difference in the lateralisation of tactile-evoked potentials when a stimulus was evoked to the index fingers of patients with schizophrenia and age- and sex- matched controls. P3 (P300) abnormalities (showing differences from controls) have been reported in schizophrenia, behavioural problems,(Iacono ea, 2002) memory disorders like Alzheimer’s disease, attentional disorders, and, as a trait marker, in the offspring of alcoholics,(Polich ea, 1994) and in affective disorders (Hall ea, 2009); abnormalities may involve amplitude, latency or the positioning of the peak over the head. The subject looks at a smoothly moving target, such as a pendulum or a moving spot. Excess jerkiness - a disrupted, jagged pattern - is found in most, but not all, schizophrenic subjects, in about 45% of their parents and siblings - who may not have overt illness, and in around 8% of the general population.
