A weaker association was found between the concentrations of pentachlorophenol in urine and hexachloro benzene in serum acne 9gag cheap cleocin 150mg on-line, which was statistically significant only for men. These results suggested that formation of the cysteine conjugate is a quantitatively important meta bolic pathway in humans, especially in persons with high hexachlorobenzene body burdens. Moreover, pentachlorobenzenethiol is a urinary marker of the internal dose of hexachlorobenzene and of glutathione-mediated metabolism (To-Figueras et al. In rats fed hexachlorobenzene for 4 weeks, subsequent food deprivation appeared to enhance the toxic response (liver hypertrophy), implying decreased mobilization of hexachlorobenzene residues into fat and resulting in greater accumulation of hexachlorobenzene in plasma, liver, brain and adrenal glands (Villeneuve et al. In rhesus monkeys (Macaca mullata) given hexachlorobenzene at a dose of 8, 32, 64 or 128 mg/kg bw per day by gavage for 60 days, body fat and bone marrow had the highest concentrations, followed by adrenal glands, liver, kidney, brain, ovaries, muscle and serum. The serum concentrations did not appear to correspond to the dose (Knauf & Hobson, 1979). After administration of a single intravenous injection of hexachlorobenzene to male beagles, the chemical was initially found primarily in the lung (2 h) but after 8 h was found primarily in the fat. Excretion in these dogs occurred essentially through the bile and faeces, urinary excretion being of less importance (Sundlof et al. Absorption of hexachlorobenzene applied dermally to male Fischer 344 rats increased from 1% to 9. In adult female Sprague-Dawley rats dosed with 50 mg/kg bw hexachlorobenzene by gavage, the chemical was found to concentrate primarily in the fat and also in endocrine glands with large lipid components, such as the follicular fluid of the ovary and thyroid. The concentrations of residues of hexachlorobenzene in nine rats given 50 mg/kg bw per day were significantly (p < 0. The concentrations of residues of hexachlorobenzene in the ovary were greater than those in the thymus, liver or lung (Foster et al. Hexachlorobenzene was found in the milk of cows given the compound (Fries & Marrow, 1976) and in the organs of 18-day-old offspring of rat dams fed a diet containing hexachlorobenzene (Mendoza et al. Toxicokinetics demonstrated that hexachlorobenzene is transferred across the placenta and into breast milk in rodents (Courtney & Andrews, 1985; Courtney et al. A similar 6-day study of pregnant hamsters and guinea-pigs showed that the hamster fetuses had fivefold greater concentrations of hexachlorobenzene than the guinea-pig fetuses (Courtney et al. The distribution in infants showed concentration in fat, bone marrow and adrenal glands (Bailey et al. When pregnant Sprague Dawley rats were given a diet containing hexachlorobenzene during gestation and lactation (35 nmol/100 g diet [100 g/kg diet]), about 0. A large proportion of the hexachlorobenzene body burden was lost during lactation, and the concentration in the stomach contents of suckling pups was highest on day 2 after birth (Nakashima et al. The major urinary metabolites were pentachlorophenol, tetra chlorohydroquinone and pentachlorothiophenol. The other urinary metabolites were tetrachlorobenzene, pentachlorobenzene, 2, 4, 5 and 2, 4, 6-trichlorophenols and 2, 3, 4, 6 and 2, 3, 5-6-tetrachlorophenols; 2, 3, 4-trichlorophenol and other tetrachloro phenols were present in traces amounts. Examination of 1 g of liver tissue from adult female Wistar rats given 178 mol/kg bw [50. The authors hypothesized that the sulfur in the latter two compounds was derived from glutathione (Koss et al. Male and female Fischer 344 rats were dosed every other day for 103 days with 50 mol/kg bw [14. Urine was collected periodically and analysed for pentachlorophenol, 2, 3, 5, 6-tetrachlorobenzene-1, 4-diol and penta chlorothiophenol. The combined urinary excretion of these metabolites was greater in females than males, especially during the first 10 weeks. Pentachlorothiophenol was present at particularly high concentrations in the urine of females. The male:female ratios for pentachlorophenol and pentachlorothiophenol in bile were identical to those Figure 1. Excretion of metabolites by both males and females was stimulated by pretreatment with diethylstilbestrol. No sex differences in metabolism were observed in immature rats (Rizzardini & Smith, 1982). A study of the metabolism of hexachlorobenzene in isolated hepatocytes from male and female Fischer 344 adult rats showed that sex differences in metabolism did not explain the differences in porphyria development. The significant metabolites were pentachlorophenol, pentachlorothiophenol and tetrachloro-1, 4-benzenedithiol. Likewise, covalent binding of [14C]hexachlorobenzene to protein after incubation with hepatocytes could not account for the sex-dependent porphyrogenic activity (Stewart & Smith, 1987). Studies in vitro and analysis of tissues after administration of pentachloronitrobenzene in vivo showed that conjugation with glutathione and hydrolysis of the conjugates to yield free pentachlorothiophenol did not differ between males and females. These findings tend to reinforce the view that an active renal secretory mechanism, probably induced by estrogens during sexual maturation, is responsible for the highly efficient excretion of sulfur derivatives of hexachlorobenzene and pentachloronitrobenzene by female rats (To-Figueras et al. The metabolism of [14C]hexachlorobenzene was studied in microsomes derived from 12-week-old male Wistar rats. In addition, a considerable amount of covalent binding of radiolabel to protein was found: 11 pmol covalent binding per 4 mg microsomal protein in an incubation mixture containing 25 mol/L hexachlorobenzene. In order to establish the potential role of reductive dechlorination in the covalent binding, the anaerobic metabolism of hexachlorobenzene was investigated. Incubation at low oxygen concentrations indicated a relationship between covalent binding and micro somal oxidation of hexachlorobenzene. The finding of conversion-dependent covalent binding indicated that less than 10% of the covalent binding occurs during conversion of hexachlorobenzene to pentachlorophenol, and the remainder is produced during conversion of pentachlorophenol to tetrachlorohydroquinone, which is in redox equi librium with the corresponding semiquinone and quinone (chloranil). These results indicate the involvement of chloranil or the semiquinone radical in covalent binding during microsomal hexachlorobenzene metabolism (van Ommen et al. In rats given diets containing either hexachlorobenzene or its metabolite penta chlorobenzene for 13 weeks, both compounds were oxidized to pentachlorophenol and tetrachlorohydroquinone, which were the only two common metabolites excreted in urine. Male and female Sprague-Dawley rats were given five consecutive doses of 1 g/kg bw hexachlorobenzene by gavage over 2 days. The cumulative dose produced porphyria in female but not male rats after a delay of 6 weeks. The hepatic glutathione concentration showed a diurnal cycle in both male and female rats, which was more pronounced in males; the minimum concentration was observed 12 h after dosing. The glutathione concentration in hexachlorobenzene-treated male rats was significantly lower than that in controls at 6, 18 and 24 h, whereas no significant difference was observed in hexachlorobenzene treated female rats. Biliary excretion of a metabolite originating from glutathione conjugation of hexachlorobenzene was higher in male than in female rats. The exposure to hexachlorobenzene led to the development of bullae on sun-exposed areas, hyper pigmentation, hypertrichosis and porphyrinuria. Samples of breast milk from the mothers of these infants were shown to contain hexachlorobenzene (Peters et al. Follow up studies of 32 of the patients have shown that abnormal porphyrin metabolism and active symptomatology persisted 20 years after ingestion of hexachlorobenzene (Peters et al. After exposure beginning in childhood, small stature, small hands and painless arthritis were present. Of particular note, enlarged thyroids were present in 25% of men and 60% of women in comparison with 5% of unexposed persons from this region of Turkey. Two persons died of liver failure; one was a 27-year-old man and the other a 54-year-old woman during treatment for tuberculosis (Cripps et al.

Patient susceptibility to the specific toxin can vary skin care juarez order cheap cleocin line, and changes in mental status or cardiac and respiratory function. Gastrointestinal and clinical features may not correlate directly with the laboratory testing values. Compromise of renal, the clinical features can also be delayed up to 1 month after exposure to the liver, and cardiac function may also occur, depending on the severity and nature toxin. Differential Diagnosis: Sleep disorders related to the use of or withdrawal Course: the course is variable, depending on the chronicity and severity of from hypnotics or stimulants must be ruled out. In patients with symptoms of exposure to the toxin and whether consequent long-term abnormalities develop. Also, children are likely to ingest certain toxic substances and can be Diagnostic Criteria: Toxin-Induced Sleep Disorder (780.

The symptoms do not meet the diagnostic criteria for any other sleep disor Pathology: Many changes can occur, depending on the specific toxin. Fatty degeneration of the heart, liver, and kidneys and bone-marrow depression may also occur with exposure to many organic toxins. Circadian Rhythm Sleep Disorders the circadian rhythm sleep disorders comprise a third section of dyssomnias and are grouped because they share a common underlying chronophysiologic basis. When internal factors, such as neurologic disease, or external factors, such as environmental or social circumstances, produce a circadian rhythm sleep disorder, diagnostic subtypes can be specified with the diagnosis of intrinsic type or extrin sic type, respectively. Three circadian rhythm sleep disorders have intrinsic and extrinsic subtypes: delayed sleep-phase syndrome, advanced sleep-phase syn drome, and non-24-hour sleep-wake disorder. In most circadian rhythm sleep disorders, the underlying problem is that the patient cannot sleep when sleep is desired, needed, or expected. As a result of sleep episodes occurring at inappropriate times, the corresponding wake periods may occur at undesired times. However, intermittent sleep episodes may occur in some disorders, including the irregular sleep-wake pattern. In the 1979 Diagnostic Classification of Sleep and Arousal Disorders, the sleep-wake schedule disorders were divided into two groups: transient and per sistent disorders. This subdivision has not been retained in the International Classification of Sleep Disorders because the duration of a disorder can now be specified and coded separately on axis A. For additional information on the chronophysiologic basis of this group of dis orders, the reader is referred to current texts on circadian rhythms, chronobiolo gy, and chronophysiology. If the cause of the altered sleep timing is another sleep ing of takeoff and arrival, and individual susceptibility. The sleep-wake distur disorder, sole diagnosis should be of the specific sleep disorder; diagnosis of the bances generally abate after two to three days in the arrival location. For example, are often associated with, but are not entirely dependent upon, sleep deprivation. Because the primary sleep diag ing of physiologic functions other than sleep and waking may take eight or more nosis is narcolepsy, however, the patient should not receive a second diagnosis of a days. Similarly, patients with mood performance impairment similar to those experienced by shift workers. Only the primary psychiatric diagnosis should be stated, Associated Features: Social or occupational dysfunction may occur, related to however, unless the sleep pattern is unrelated to the mental disorder or the mental decrements in daytime alertness and performance in the new time zone. Jet lag disorder is in remission and the sleep disorder is the predominant diagnosis. Only if the timing of sleep is the predom inal distention, dependent edema, and intermittent dizziness that can occur solely inant cause of the sleep disturbance and is outside the societal norm would a diag or largely as a function of airplane cabin conditions and are not truly symptoms nosis of a circadian rhythm sleep disorder be stated. If the setting of limits is a function of a caretaker, the sleep inconvenience, which, although sometimes severe, is self-limiting, with very few disorder is more appropriately diagnosed within the extrinsic subsection of the apparent symptoms by the third day after the flight. An alternating pattern of good and poor sleep may also occur for up to a Arousal Disorders. The Predisposing Factors: Reports are mainly anecdotal, but some experimental simpler term shift work sleep disorder is preferred to the previous longer and more evidence suggests that individuals over age 50 are more likely to suffer from jet cumbersome term, work shift change in conventional sleep-wake schedule. Neurotic extroverts have been found to phase adjust faster than neurotic introverts and, thus, would be expected to experience less jet lag. Synonyms and Key Words: Jet lag, transmeridian flight desynchronosis, air travel, transmeridian dyschronism.

WhatsApp, Signal and responsible and trustworthy technologies others offer encrypted communication for children. Many parents also struggle with conficting messages that they should limit screen time, on the one hand, or get the latest device so their children can keep up, on the other. So the task is to fnd ways to provide children with the support and guidance they need to make the most of their online experiences. They also worried that books and the printing press would lead to what today As seen in previous chapters, whether we would call information overload. Their use by children is harder loneliness, stress, depression or problems to monitor. Conversely, children who beneft from digital devices gather information on them, too. For example, a report from the high-connectivity contexts fnd it diffcult to Swedish Media Council described how estimate how much time they spend with parents in Sweden were at once quite digital technology, because they are more positive about the benefts their children or less using it all of the time.

Veterans 65 years and older comprise 70% of those with diabetes skin carecom order cleocin 150 mg fast delivery, reflecting the older age distribution of this population. Standards of care are determined on the basis of all clinical data available for an individual patient and are subject to change as scientific knowledge and technology advance and patterns evolve. The Champions and the Work Group also provided direction on inclusion and exclusion criteria for the evidence review and assessed the level and quality of the evidence. The specialties and clinical areas of interest included endocrinology, internal medicine, nutrition, pharmacy, health education, nursing, medical management, ambulatory care, and family practice. A strong recommendation indicates that the Work Group is highly confident that desirable outcomes outweigh undesirable outcomes. If the Work Group is less confident of the balance between desirable and undesirable outcomes, they give a weak recommendation. Thus, differences in recommendations across guidelines may reflect differences in the grading system used as well as differences in the evidence reviewed and/or how the strength of the evidence is evaluated by the Work Group. Additional information regarding these categories and their definitions can be found in Appendix A. The categories for the recommendations included in the 2017 version of the guideline can be found in the section on Recommendations. In order to report the strength of all recommendations using a consistent format. The process for developing the initial draft is described in more detail in Drafting and Submitting the Final Clinical Practice Guideline. Once a near-final draft of the guideline was agreed upon by the Champions and Work Group members, the draft was sent out for peer review and comment. For transparency, all reviewer feedback was posted in tabular form on the wiki site, along with the name of the reviewer. All feedback from the peer reviewers was discussed and considered by the Work Group. Summary of Patient Focus Group Methods and Findings When forming guideline recommendations, consideration should be given to the values of those most affected by the recommendations. It is important to note the focus group was a convenience sample and the Working Group recognizes the limitations inherent in the small sample size. Less than 10 people were included in the focus group consistent with the requirements of the federal Paperwork Reduction Act, 1980. Thus, the Working Group made decisions regarding the priority of topics to discuss at the focus group. These limitations, as well as others, were considered throughout the use of the information collected from the discussion for guideline development. The following concepts are aspects of care that are important to patients that emerged from the discussion. Additional details regarding the patient focus group methods and findings can be found in Appendix D. Using shared decision-making, consider all treatment options and develop a treatment plan based on the balance of risks, benefits, and patient-specific goals, values, and preferences. A structured algorithm accompanies the guideline to provide an overview of the recommendations in the context of the flow of patient care and clinician decision making and to assist with training providers. The algorithm may be used to help facilitate translation of guideline recommendations into effective practice. Clinicians must be skilled at presenting their patients with understandable and actionable information regarding both individual treatments and levels and locations of care. Use of an empathetic and non-judgmental (versus a confrontational) approach facilitates discussions sensitive to gender, culture, and ethnic differences. The information that patients are given about treatment and care should be culturally appropriate and also available to people with limited literacy skills. It should also be accessible to people with additional needs such as physical, sensory, or learning disabilities. Family involvement should be considered if appropriate, especially in elderly patients. Lastly, they should involve the patient in prioritizing problems to be addressed and in setting specific goals regardless of the selected setting or level of care. The algorithm serves as a tool to prompt providers to consider key decision points in the course of an episode of care. The use of the algorithm format as a way to represent patient management was chosen based on the understanding that such a format may promote more efficient diagnostic and therapeutic decision making and has the potential to change patterns of resource use. Standardized symbols are used to display each step in the algorithm and arrows connect the numbered boxes indicating the order in which the steps should be followed. We recommend shared decision-making to enhance patient knowledge Strong for Reviewed, and satisfaction. We recommend that all patients with diabetes should be offered ongoing Strong for Reviewed, individualized diabetes self-management education via various modalities New-replaced tailored to their preferences, learning needs and abilities based on available resources. We suggest offering one or more types of bidirectional telehealth Weak for Reviewed, interventions (typically health communication via computer, telephone or New-replaced other electronic means) involving licensed independent practitioners to patients selected by their primary care provider as an adjunct to usual patient care.

We recommend a nutrition intervention strategy reducing percent of energy Strong for Reviewed, from carbohydrate to 14-45% per day and/or foods with lower glycemic New-added index in patients with type 2 diabetes who do not choose the Mediterranean diet. We recommend against targeting blood glucose levels <110 mg/dL for all Strong Reviewed, hospitalized patients with type 2 diabetes receiving insulin.

We recommend shared decision-making to enhance patient knowledge and satisfaction. Key principles include the patient/family readiness, provision of benefits and harms of all options in understandable tools, and incorporation of preferences. This should include, at a minimum, diagnosis, difficulties in management, and times of transition or development of complications.

Physiologically neuromyotonia is characterized by continuous motor unit and muscle bre activity which is due to peripheral nerve hyperexcitability; it is abolished by curare (cf skin care for eczema 150 mg cleocin overnight delivery. Neuromyotonia may be associated with autoantibodies directed against presynaptic voltage-gated K+ channels. Around 20% of patients have an 239 N Neuronopathy underlying small cell lung cancer or thymoma, suggesting a paraneoplastic aeti ology in these patients. Neuromyotonia has also been associated with mutations within the voltage-gated K+ ion channel gene. Neuromyotonia usually improves with symptomatic treatments such as car bamazepine, phenytoin, lamotrigine, and sodium valproate, in combination if necessary. Paraneoplastic neuromyotonia often improves and may remit after treatment of the underlying tumour. Cross References Fasciculation; Myokymia; Myotonia; Paramyotonia; Pseudomyotonia; Stiffness Neuronopathy Neuronopathies are disorders affecting neuronal cell bodies in the ventral (ante rior) horns of the spinal cord or dorsal root ganglia, hence motor and sensory neuronopathies, respectively. Cross Reference Neuropathy Neuropathy Neuropathies are disorders of peripheral nerves. These clinical patterns may need to be differentiated in practice from disor ders affecting the neuronal cell bodies in the ventral (anterior) horns of the spinal cord or dorsal root ganglia (motor and sensory neuronopathies, respectively); and disorders of the nerve roots (radiculopathy) and plexuses (plexopathy). Clinical signs resulting from neuropathies are of lower motor neurone type (wasting, weakness, reex diminution, or loss). Mononeuropathies often result from local compression (entrapment neuropathy), trauma, or diabetes. Polyneuropathies may have genetic, infective, inammatory, toxic, nutritional, and endocrine aetiologies. Many neuropathies, particularly polyneuropathies in the elderly, remain idiopathic or cryptogenic, despite intensive investigation. If these other signs are absent, then isolated nuchal rigidity may suggest a foraminal pressure cone. It may also occur in syndromes causing predominantly axial (as opposed to limb) rigidity. This nuchocephalic 241 N Nyctalopia reex is present in infants and children up to the age of about 4 years. Beyond this age the reex is inhibited, such that the head is actively turned in the direction of shoulder movement after a time lag of about half a second. Cross References Age-related signs; Primitive reexes Nyctalopia Nyctalopia, or night blindness, is an impairment of visual acuity specic to scotopic vision, implying a loss or impairment of rod photoreceptor function. Patients may spontaneously complain of a disparity between daytime and noc turnal vision, in which case acuity should be measured in different ambient illumination. The nature of the nystagmus may permit inferences about the pre cise location of pathology. Observations should be made in the nine cardinal positions of gaze for direction, amplitude, and beat frequency of nystagmus. However, since it is the slow phase which is pathological, it is more elo quent concerning anatomical substrate. The intensity of jerk nystagmus may be classied by a scale of three degrees: 1st degree: present when looking in the direction of the fast phase; 2nd degree: present in the neutral position; 3rd degree: present when looking in the direction of the slow phase. Pendular or undulatory nystagmus: In which the movements of the eyes are more or less equal in ampli tude and velocity (sinusoidal oscillations) about a central (null) point. This is often congenital, may be conjugate or disconjugate (sometimes monocular), but is not related to concurrent internuclear ophthalmo plegia or asymmetry of visual acuity. A slow phase with exponentially increasing veloc ity (high-gain instability, runaway movements) may be seen in congenital or acquired pendular nystagmus. The pathophysiology of acquired pendular nys tagmus is thought to be deafferentation of the inferior olive by lesions of the red nucleus, central tegmental tract, or medial vestibular nucleus. Central vestibular: unidirectional or multidirectional, 1st, 2nd or 3rd degree; typically sustained and persistent. Cerebellar/brainstem: commonly gaze-evoked due to a failure of gaze-holding mechanisms. Congenital: usually horizontal, pendular-type nystagmus; worse with xation, attention, and anxiety. Many pathologies may cause nystagmus, the most common being demyelina tion, vascular disease, tumour, neurodegenerative disorders of cerebellum and/or brainstem, metabolic causes. Pendular nystagmus may respond to anticholinesterases, consistent with its being a result of cholinergic dysfunction. Periodic alternating nystagmus responds to baclofen, hence the importance of making this diagnosis. These symp toms are thought to reect critical compromise of optic nerve head perfusion and are invariably associated with the nding of papilloedema. Obscurations mandate urgent investigation and treatment to prevent permanent visual loss. Cross Reference Papilloedema Obtundation Obtundation is a state of altered consciousness characterized by reduced alert ness and a lessened interest in the environment, sometimes described as psy chomotor retardation or torpor. An increased proportion of time is spent asleep and the patient is drowsy when awake. Cross References Coma; Psychomotor retardation; Stupor Ocular Apraxia Ocular apraxia (ocular motor apraxia) is a disorder of voluntary saccade initia tion; reexive saccades and spontaneous eye movements are preserved. Ocular apraxia may be overcome by using dynamic head thrusting, with or without blinking (to suppress vestibulo-ocular reexes): the desired xation point is achieved through reex contraversive tonic eye movements to the midposition following the overshoot of the eyes caused by the head thrust. Cross References Apraxia; Saccades Ocular Bobbing Ocular bobbing refers to intermittent abnormal vertical eye movements, usu ally conjugate, consisting of a fast downward movement followed by a slow return to the initial horizontal eye position. The sign has no precise localizing value, but is most commonly associated with intrinsic pontine lesions. Its patho physiology is uncertain but may involve mesencephalic and medullary burst neurone centres. Cross Reference Ocular dipping Ocular Dipping Ocular dipping, or inverse ocular bobbing, consists of a slow spontaneous down ward eye movement with a fast return to the midposition. This may be observed in anoxic coma or following prolonged status epilepticus and is thought to be a marker of diffuse, rather than focal, brain damage. Reverse ocular dipping (slow upward ocular bobbing) consists of a slow upward movement followed by a fast return to the midposition. Cross Reference Ocular bobbing Ocular Flutter Ocular utter is an eye movement disorder characterized by involuntary bursts of back-to-back horizontal saccades without an intersaccadic interval (cf. Ocular utter associated with a localized lesion in the paramedian pontine reticular formation. It has occasionally been reported with cerebellar lesions and may be under inhibitory cerebellar control.

Disorder of memory includes the hip pocampal defects of diminished storage and accelerated forgetting; deja vu and jamais vu also occur skin care facts purchase cleocin on line amex, as described above. There may be altered states of consciousness such as a fugue, with impaired registration. Panoramic recall, in which the patient may feel that he is rapidly re-enacting long periods of his life, is also described. Affective Disorder of Memory Memory is not only disturbed by organic damage to the brain itself; it is also affected by emotion. This is certainly true of normal, healthy people, in whom the affective state strongly infuences the processes of remembering and forgetting. It is also true of those with affective and schizo phrenic psychoses, and of neuroses and personality disorders. There is also substantial evidence of an association between depression and generic memory impairment. It is thought that mood disorder, such as depression, reduces the amount of cognitive processing resources available for a given task, and in the memory domain this is manifest as defcits in the elaboration, organization, encoding and retrieval of material into and out of memory (Dalgleish and Cox, 2002). This mood-congruent memory effect is similar but distinct from state-dependent memory, which refers to the memory bias for material that is learned in a particular mood and is more easily retrieved if the individual is in that same mood during retrieval. Rates of forgetting are infuenced by the personal meaningfulness of the information, the conceptual style of the individual, the degree of processing and elaboration of the information and age. It is likely that normal forgetting is determined by disuse or interference by more recently learned or more vivid material and underpinned by physiological or metabolic processes (Lezak et al. In proac tive interference, newly learned material interferes with the recall of previously learned material. In retroactive interference, previously learned material interferes with the recall of newly learned material (see Eysenck and Keane, 2010 for a fuller discussion). The process of repression or selective forgetting, however, suggests that forgetting is not simply down to errors in the fling and retrieval mechanism. Forgetting is subject to the infuence of affect: which sensations are registered, what is retained and for how long and what information is available for recall. Other forms of active forgetting exist, including motivated forgetting which subsumes repression as an example, and also the deliberate forgetting of where we put our glasses yesterday when we are looking for them today! Directed forgetting is the term for the process by which we actively use executive control proc esses within the prefrontal cortex to forget items that we do not wish to recall. It is obvious from the foregoing that forgetting is an important and normative process. Questions are answered with fuency, and the story appears to be believed implicitly by the pseudologic himself. This usually occurs with an associated personality disorder of histri onic or dissocial type, and often when the individual is experiencing a major life crisis such as facing criminal proceedings. The picture is of a very isolated person, without family or friends, drifting into the accident and emergency department of a large hospital in a strange city late at night, with stories of his own exploits and importance and the unfortunate vicissitudes he has experienced. With personality disorders and also with affective disorders, especially at times of heightened emotion, memory is falsifed and distorted, and events and circumstances are misrepresented. So the grandiose delusions and memory disturbance of general paresis may result in falsifcation and distortion of events remembered. Similarly, confabu lation as in the Korsakov state is associated with falsifcation. This was stated by a patient who had quite suddenly come to believe that all her actions were being observed and, subsequently, her behaviour controlled. This is a backdating of delusion to a time before the patient was ill, based on an admixture of remembered true events and delu sional elaboration of the meaning of those events. This has been described by some authorities as a form of confabulation (Nathaniel-James and Frith, 1996; McKenna et al. In the original study, when subjects were presented with narratives and asked to recall them, con fabulation was defned as recall of information not present in the original narrative. The degree of confabulation was related to problems in suppressing inappropriate responses and formal thought disorder. It is clear that it is very uncommon in a spontane ous form, and when it does occur it always seems to take the form of so-called fantastic confabu lation Simple, momentary, or provoked confabulations, on the other hand, appear to be commonplace. As well as occurring in the normal state and in personality disorders, it is a prominent feature of affective disturbances. Memory itself was accurate, but on remonstrating on any particular point of fact, further depressive explanations of events would be given. For instance, the marriage licence was described as a forgery, and com plicated legal explanations were given as to why the house did not belong to her and her husband. In mania, unacceptable events or opinions may be brushed aside as not having occurred and unrealistic goals pursued as though there were nothing to prevent their attainment. A person makes a witty remark, or writes a haunting melody, without realizing that he is quoting (plagiarizing) rather than producing something original. The process is seen when words or phrases come into popular usage for a few months or years by some process of mass spread, in which people using the expression believe they are introducing a new idea. This is a defect of recall that can be seen as a successful defence mechanism; it helps to maintain the integrity of the person. However, in the affect of hope lessness, reactivation of memories of previous failures is a frequent reason for perpetuating neurotic thinking and behaviour (Engel, 1968). Psychogenic amnesia may appear without any organic disease being present, but the presentation of organic brain disease is always modifed by psy chogenic factors (Pratt, 1977). Misnaming objects and momentary loss of memory for words in healthy subjects may result from faulty retrieval from short and long-term memory stores rather than from the psychoana lytic explanation of repression. Such errors may be categorized as acoustic or semantic; acoustic errors tending to occur in short-term stores of up to 30 seconds and semantic ones in long-term stores after more than fve minutes (Shallice and McGill, 1977). Dissociative (Hysterical) Fugue the symptoms pertaining to dissociative (conversion) disorders (hysteria) in the International Classifcation of Diseases (World Health Organization, 1992) are of two types: conversion and dissociation. In dissociation, there is a narrowing of the feld of consciousness, with subsequent amnesia for the episode. The person appears to be in good contact with his environment and usually behaves appropriately, maintaining basic self-care, although he sometimes displays disinhibition. The duration of the episode can be very variable, from a few hours to several weeks, and the subject may travel considerable distances. As he walked about the streets, he found he was near an airport terminal and, to his surprise, he discovered that he was in Montreal. Germane to his adventure was the history of a catastrophic row and the breakdown of his marriage just before he took off. Thus the features of dissociative fugue are dissociative amnesia, purposeful travel beyond the usual everyday range and maintenance of basic self-care (World Health Organization, 1992). The Ganser state is very rarely seen in English prisons but, when it does occur, it is more likely in those awaiting trial than those already sentenced (Enoch, 1990). There has been considerable argument as to whether this condition is primarily hysterical or an organic psychosis, with different authors supporting each contention (Latcham et al.
