For example discount tadapox 80mg on-line erectile dysfunction in early 30s, in learning cycling and driving a care purchase generic tadapox on line erectile dysfunction 19, the transfer takes place because of the common elements like stearing movements, knowledge of the rules of the road and looking ahead. Ex · Attention to loud sounds · Bright lights · Strong penetrating odours Factors increasing attention by external factors: 1) Nature of the stimulus: More attractive stimulus catches maximum attention (Picture) 2) Locationof the stimulus: Stimulus in front of the eye attracts our attraction 3) Intensity : Loud sound, bright colors 4) Change in the intensity of the stimulus: Ticking of a clock in our room may not attract our attention but when it stops our attention is attracted 5) Movement: A fast moving electric sign attracts our attention 6) Size: Bigger size attracts more attention 7) Contracts: A single man among the many woman, a spot on a clean white dress attracts our attention 8) Novelty: A new fashion dress attracts our attention 9) Repetition: Repeated cry, repeated ringing of a call bell attracts our attention 77 Factors increasing attention by internal factors: 1) Interest: When we are motivated to a goal 2) Motives: When a child is hungry he looks for a feeding bottle rather than a toy 3) Experience: We attend to object with which we are familiar 4) Mental set: While excepting a friend, we perceive any knocking sound as that of friend’s footstep 5) Emotional stage: Under stressful conditions we fail to perceive our surroundings fully Voluntary or habitual: There is no conscious effort of sensation. Ex: The attention that a teacher gives to her students Span of attention: The maximum amount of material that can be attend to in one period of attention is called span of attention Distraction of attention: Refers to shifting of attention from one stimulus to another. External distraction: Noise pollution Internal distraction: Pain headache Division of attention: Refers to the process of dividing our attention equally and simultaneously between two or more objects. Ex: While students reading a book may hear his favorite song Perception : Perception is the process by which we discriminate among stimuli and interpret their meanings and appreciate their significance. Ex When we hear a sound, we are able to identify it as being produced by an aero plane Perceptions are divided in to 1) Visual perception 2) Auditory perception Factors influencing perception: · Functioning of the sense organs · Functioning of the brain · Previous experience · Frequency of exposure · Psychological state of the individual · Interest · Motivation · Behavior of the organism Theories of laws of perceptual organization: 1) Figure – ground relationship: The most fundamental process in form perception is the recognition of a figures standing out from a background. This is because the polar bear is white in color 78 In the above figure you see the light portion as a figure, you will see a water glass or candle holder, if you see the dark portion as a figure, you will see two faces. Either one is a figure against background Grouping of stimuli in perceptual organization: Stimuli are grouped into the smallest possible pattern that has meaning. Important principles of grouping are proximity, similarity, symmetry, closure and continuation Proximity: When objects are close to each other, the tendency is to perceive than together rather than separately. We see three sets of two lines each and not six separately lines Proximity Similarity: Items that most closely resemble each other or perceived as units In above figure the circles and triangles are seen as two vertical rows of triangles and one row of circles and not three horizontal rows of triangles and circles Symmetry: Items that form symmetrical units are grouped together We see three sets of brackets. We do not see six unconnected lines Closure: Items are perceived as complete units even though they may be interrupted by gaps Continuation: Anything which extends itself into space in the same shape, size and color with out a break in perceived as a whole figure. We do not see a straight line with small semi circles above and below it Perceptual constancies: Perceptual constancies refers to our tendency to perceive objects as relatively stable and unchanging despite changing information. Perceptual constancies 1) Space constancy 2) Sex constancy 3) Brightness and color constancy 4) Perception of space binocular depth cues 5) Visual monocular clues Types of perceptual constancies: 1) Observer characteristics: Depends greatly on past experience and learning 2) Depth perception: Is the ability to perceive space and distance accurately 3) Binocular cues: Helps in the perception of depth by integrating and synchronizing the images of both the eyes. According to psychologist Ward, “it is the complete psychosis involving cognition, pleasure – pain and conation”. The difference between motives and emotions are as follows: Emotions are usually aroused by external stimuli and that emotional expression is directed toward the stimuli in the environment that arouses it. Motives on the other hand, are more often aroused by internal stimuli and naturally directed towards certain objects in the environment. Most of the motivated behaviour has some affective or emotional accompaniment although we may be too pre occupied in our striving towards goal. The bodily effects of pain, hunger, fear and rage have all the emotions of characteristically, negative polarity. The sympathetic system is responsible for the following changes: 1) Blood pressure and heart rate increases. Nerve impulses with sympathetic system, which reach adrenal glands located on the top of the kidneys, trigger the secretion of hormones. Theories of emotion: James theory or emotion proposes the following sequences of events in emotional state. The major objection to James Lang theory came from Cannon who pointed out 1) That changes do not seem to differ very much from one emotional state to another. James Langes Theory Perception of Activation of Feed back to brain emotion Visceral and from bodily producing skeletal responses produce stimulus responses experience of emotion Canon theory Messages to cortex produce experience Perception of Stimulus processed by of emotion emotion Thalamus, which producing simultaneously send stimulus messages to the cortex and other parts of the body Messages from thalamus activates visceral and skeletal responses Emotion when sufficiently intense can seriously impair the process that control organized behavior. Motion pictures and recording of children’s cries indicate that the infants’ response to stimuli designated to arouse emotion are very diffuse and lacking in organization. Emotional shocks and hurts suffered by individuals at an early age can handicap them as long as they live. Children sooner or later acquire the capacity for experiencing negative emotions such as anger, fear, and also sorrow or grief to an intense degree. This capacity develops, before the child is mature enough to use language, to formulate his experience in words. These improvements in the young child’s ability to respond in specific ways to situations that arouse him, parallel the development of his mental and motor abilities. As the child’s intellectual and motor capacity matures, he acquires large variety of means and forms of expression such as overt and direct to more graded covert and indirect. If a person may mask intense feeling of anger tat occurs when someone hunts his pride very sharply and then still harboring his anger may explode on another occasions because of a very trivial affront. The most important factors in a child’s emotional development and the affection that he receives from his parents, peer group and society. The more genuine the parents love for the child, the, more the child tends to feel free to love other people. All physiological healthy nurses are likely to feel some affection for patients in their charge or with whom they have a chance to associate even though the children are not their own. Their un loved person may suffer in connection with the development of positive attitudes and concepts concern ing his own worth. This personality is not fixed state but dynamic totality, which is continuously changing due to interaction with the environment. Definition of personality: In the words of Munn, it is characteristic integration of an individual’s structure. In the words of Gorden Allport, “personality is the dynamic organization within the individual of those psychophysical systems, that determine his unique adjustment to his environment” The personality is the organization of the internal and external activities. Personality is the total quality of behavior, attitudes, interests, capacities, aptitudes and behavior patterns, which are manifested in his relation with the environment. However as a person genetic inheritance interacts with and is shaped by environmental factors, the emerges a self structure that becomes an important influence in shapijgn further development and behavior. A trait is an enduring and consistent characteristic of a person that is observed in a wide variety of situations. In fact All port and Odbert have listed 17,593 words in English, which are adjectives standing for personality traits. Norman listed 5 terms extroversion, agreeableness, consciousness, and emotional stability and culture. In situations of worry, panicking, stress and over emotionality a high level activity could affect performance adversely in academic work of pupils, resulting in learning disabilities. The type personality: It is older than the trait approach, which depends upon modern statistical procedures. The athletic and asthenic type of body build, go with what is known as schizothyme personality and the pyknic body goes with cyclothymic personality. Psychological theory of personality: Personality theories are grouped under three major heads 1) Psychodynamic theories. Psychodynamic theories of personality: Psychoanalytic theories of personality are referred to as psychodynamic theory. This theory at tempts to understand personality in terms of mental functions may be rational, irrational, conscious or unconscious. Freud’s theory of psychoanalysis emphasizes man as dynamic system of energies and main store house of such energies in unconscious. From anxiety, defense mechanism or unconscious attempts to reduce anxiety by denying or destroying realty,. The technique of Eric Berne’s transactional refers to wholesome transaction from childhood to adulthood.

Persons who have syphilis might seek damage, although tissue reaction to the infection can result in treatment for signs or symptoms of primary infection (i.

In these circumstances, the need for additional therapy seroreactivity without other evidence of disease. Management of Sex Partners Patients’ conditions can be diagnosed as early latent syphilis if, during the year preceding the evaluation, they had 1) a See General Principles, Management of Sex Partners. In Data to support the use of alternatives to penicillin in addition, for persons whose only possible exposure occurred the treatment of early syphilis are limited. However, several during the previous 12 months, reactive nontreponemal and therapies might be efective in nonpregnant, penicillin-allergic treponemal tests are indicative of early latent syphilis. Doxycycline absence of these conditions, an asymptomatic person should be 100 mg orally twice daily for 14 days (209,210) and tetracy- considered to have late latent syphilis or syphilis of unknown cline (500 mg four times daily for 14 days) are regimens that duration. However, better with doxycycline than tetracycline, because tetracycline early latent syphilis cannot be reliably distinguished from late can cause gastrointestinal side efects. As such, the use of Because latent syphilis is not transmitted sexually, the azithromycin should be used with caution only when treatment objective of treating patients with this stage of disease is to with penicillin or doxycycline is not feasible. Close follow- the efectiveness of penicillin in achieving this goal, limited up of persons receiving any alternative therapies is essential. In addition, birth and maternal medical records examination and a repeated course of therapy, serologic titers should be reviewed to assess whether children have congenital might fail to decline.

One study discount tadapox 80 mg line impotence organic origin definition, for example cheap tadapox 80mg otc erectile dysfunction doctors in brooklyn, found severe cardiac involvement in 10% of those with arthritis, 33% of those with arthralgia, and 50% of those with no joint symptoms (19). Following a streptococcal infec- tion, some patients develop arthropathy that differs from acute rheu- matic arthritis. Gonococcal arthritis can present a problem because it occurs frequently in adolescents who do not have localized gonococcal disease, and whose blood and joint ﬂuid cultures are negative in microbiological tests. The diagnosis can be helped by an epidemiological history and characteristic gonococcal skin lesions (if present), in addition to gonococcal cultures of urethra, cervix, rectum and pharynx. A diagnosis of Lyme disease should take into account the season of the year, geographical locale, and history of tick bites. The diagnosis can be conﬁrmed by serological studies and the patient response to anti- microbial therapy. Viremias, some of which are associated with immune complex forma- tion, may also mimic rheumatic polyarthritis. Rheumatological manifestations of other immune complex diseases such as serum sickness may be confusing, particularly when they occur in a patient who has recently received antibiotics for an upper respiratory tract infection. In juvenile rheumatoid arthritis certain associated ﬁndings, such as rash, lymphadenopathy and splenomegaly, may suggest the diagnosis. At times, the only way to arrive at a deﬁnite diagnosis is to observe the clinical course. Arthritis heals completely, unlike carditis, and leaves no pathological or functional residua. This rare condition is not a true synovitis, but rather is a periarticular ﬁbrosis of the metacar- pophalangeal joints. Sydenham’s chorea Chorea occurs primarily in children and is rare after the age of 20 years. The reasons for the variation were not apparent, but might be related to differences in susceptibil- ity to chorea in the host population, or to differences in case-ﬁnding methods. It is unknown whether particular strains of group A strepto- cocci vary in their propensity to elicit chorea. Sydenham’s chorea is characterized by emotional lability, uncoordi- nated movements, and muscular weakness (28, 29). The onset may often be difﬁcult to determine, as initially the child may become fretful, irritable, inattentive to schoolwork, ﬁdgety, or even severely disturbed. Physical uncoordination soon becomes apparent, perhaps manifested as clumsiness and a tendency to drop objects, which progresses to spasmodic, uncoordinated movements. All muscle groups may be affected, but erratic movements of the hands, feet and face are most evident. When the tongue is protruded it resembles a “bag of worms,” and speech is jerky and staccato. Handwriting becomes illegible, and the patient may stumble when attempting to walk. When the hands are extended, the dorsum assumes a “spoon” or “dish” conﬁguration due to ﬂexion of the wrist and hyperextension of the metacarpopha- langeal joints. When raising the hands above the head, the patient may pronate one or both hands (“pronator sign”). Patients with cho- rea are unable to sustain a titanic contraction; therefore, when asked to grip the examiner’s hand, their irregular, repetitive squeezes have been termed “milkmaid grip”. Although the choreiform movements are usually bilateral, they may be unilateral (hemichorea) (30). The choreiform movements disappear during sleep, decrease with rest and sedation, and can be suppressed by volition for few movements. They may be accentuated by asking the patient to perform several volun- tary movements at once. The relationship of chorea to polyarthritis and carditis was clariﬁed by the recognition that chorea has a longer latency period after anteced- ent group A streptococcal infection, as long as 1–7 months. As a result, polyarthritis and Sydenham’s chorea do not occur together; and indeed the onset of chorea often calls attention to subclinical carditis. Another consequence of the long latency period is that strep- tococcal antibody titres and laboratory measures of inﬂammation may have resolved by the time choreiform movements appears. As discussed above, when patients experience recurrent attacks of pure chorea, a preceding streptococcal infection may be difﬁcult to establish. Fre- quently, patients with chorea gravidarum, or with oral contraceptive- induced chorea, have a past history of chorea (including Sydenham’s chorea), suggesting that certain individuals may have an innate chore- iform diathesis, or that a ﬁrst attack confers an enhanced susceptibil- ity to subsequent attacks. All patients were highly compliant2 with the prophylactic regimen and were followed prospectively, with monthly throat cultures and serum antistreptococcal antibody deter- minations every three months. In most cases, a recent streptococcal infection was conﬁrmed by serological evidence, although titre in- creases were often quite modest. In four recurrences it was possible to rule out an immunologically signiﬁcant streptococcal infection within the six months preceding the episode. It was concluded either that some recurrences of Sydenham’s chorea in patients on optimal pro- phylaxis were triggered by streptococcal infections too weak and transient to be detected, or that stimuli other than streptococcal infec- tions triggered the recurrences. In only approximately two-thirds of cases of pure chorea can a recent streptococcal infection be documented, which makes differential diagnosis more difﬁcult. Non-cardiac chorea can occur owing to other collagen vascular, endocrine, metabolic, neoplastic, genetic, and infectious disorders (Table 4. Drug intoxication Drug screen, especially for phenytoin, amitriptyline, metoclopramide, and ﬂuphenazine. Pregnancy (chorea gravidarum) Hyperthyroidism Abnormal thyroid function test results. Evidence of preceding streptococcal infection Wilson’s disease Decreased serum ceruloplasmin level. Increased urinary copper excretion Kayser-Fleischer rings Anemia, hepatitis Family history a Source: (73). It is more likely, however, that in most cases the disorder is related to hormonal alterations. The role of hormonal factors in the pathogenesis of chorea is further exempliﬁed by the association of choreic disorder associated with oral contraceptive use (33, 34). Cho- rea usually begins soon after the patient has started taking oral con- traceptives and stops within a few weeks after they are discontinued. Nearly half the patients have a history of previous chorea, which may have been associated with a rheumatic attack or with nonrheumatic conditions (e. Interestingly, patients with oral contraceptive-induced chorea who later became pregnant do not necessarily develop chorea gravidarum. In addition to the above-mentioned causes of choreiform movements, simple motor tics in children or the involuntary jerks of Tourette’s syndrome may be confused with chorea. The duration of chorea is quite variable, ranging from one week to more than two years; the median duration of an attack was 15 weeks in hospitalized patients.
