The Power of Impulsivity The acquisition of goods and services on short-term credit installments is on the rise buy lasix 40mg amex. The “take it today and pay interest free in 12 months” has become the customary Christmas slogan and shopping centers have turned into pilgrimage destinations lasix 100 mg discount. Skillfully applying the principles of operant conditioning lasix 40 mg with amex, short- term positive consequences of buying behavior are promoted on the grounds of delaying costs discount lasix 100mg online. Advertising messages are loaded with words that invite immediacy of action (now, already, do not think about it, last day, take it without obligation) and encourage saying yes without allowing time for doubt. Deliberating before a decision, thinking about whether you really need it, assessing whether I really want it or if my desire is transitional or 13 Analysis of Drug Use Prevention on a Community-wide Scale estimating the costs of the acquisition would mean desisting from a large number of purchase attempts. In the realm of the personal, scientific evidence on risk factors has determined the relationship between impulsivity as a personality trait and drug use (Zuckerman, 1983). Likewise, these arguments bear a special parallel with the techniques used in treatments to break drug use habits, in which reducing the compulsive behavior by exercising reflection and anticipation of consequences is a central component of therapy. Accessibility to the Substance Substance accessibility is considered one of the major risk factors and its relationship with consumption has been repeatedly demonstrated through surveys in the general and student populations. The first refers to the actual availability of the drug supply on the market, which can be broken down into two dimensions: price and the frequency and proximity of points of sale. In addition, the measures taken to reduce the availability of alcohol, tobacco and other drugs will be reviewed. Accessibility, in turn, has a personal or subjective version consisting of individual perception of the ease of getting a particular drug. It further depends on the individual´s assessment of his or her ability to find and purchase the drug. As shown in the results of epidemiological studies, accessibility has a directly proportional relationship to substance use. Prevalence of cocaine use (last 12 months), perception of risk (consumption once per month or less) and perceived availability (easy/very easy). The chart depicts the evolution of six surveys carried out in Spain in the school population aged 14-18. Over the course of ten years, the perceived availability nearly doubled, while consumption shot up 400%. Social Perception of Risk Like accessibility, risk perception is considered one of the factors that best predict substance consumption. The lower the perceived risk of using substances, the greater the prevalence of use will be (Johnston et al. The perception of risk is a factor that rests firstly with the individual, who is ultimately the one who evaluates the consequences of his or her behavior. Nevertheless, the valence and intensity with which an individual assesses the risk posed by taking a dose of drugs is strongly linked to the perception held by the society or culture to which he or she belongs. We understand social perception to mean how or what members of a particular culture or society interpret, imagine or think about something. Sociological research findings show that speech trivializing the harmful effects of drugs permeate society and reduce the perception of risk. For 15 Analysis of Drug Use Prevention on a Community-wide Scale example, in recent years a strong social movement for the use of cannabis has developed in Spain. The organizational capacity of this movement has been demonstrated by the large number of groups, associations, meetings, exhibitions, websites and print publications that have emerged for the legalization of cannabis. Prevalence of cannabis use (last 12 months), perception of risk (consumption once per month or less) and perceived availability (easy/very easy). The results of the student population survey, which is conducted every two years in Spain, show an unequivocal relationship between cannabis use in the last 12 months (black line) and the perceived risk (blue line). Both variables maintain an inversely proportional relationship and their paths mark out a converging trajectory. The chart shows the importance of beliefs about the harmful consequences of cannabis use, as it modulates the prevalence of consumption. Ten years 16 Daniel Lloret Irles and José Pedro Espada Sánchez later the perception of risk fell 24 proportional points.

The vast majority of pediatric cases are bacteria buy 40 mg lasix with mastercard, while in adult’s bacterial and viral causes are equally common generic lasix 100 mg online. Bacterial conjunctivitis • Commonly caused by staphylococcus aureus cheap 40 mg lasix otc, streptococcus pneumonia buy lasix 40mg with amex, Hemophilic influenza, and moraxella catarrhalis • S. Symptoms:- • Patients typically complain of redness and discharge in one eye; although it can also be bilateral. Sign: - • On examination, patients will typically have purulent discharge at the lid margins and in the corners of the eye. More purulent discharge appears within minutes of wiping the lids • Red eye – due to dilatation of superficial blood vessels as apart of inflammation 36 • Edema of the conjunctiva (chemosis) and eyelids swelling • Cornea is mostly clear; but if it is involved, there will be different degree of corneal opacity it is common special in untreated and delayed patients (see color plate14) Diagnosis - Mostly clinical - Gram stains Course - It lasts for 1 - 2 weeks and then it usually resolves spontaneously. Symptoms _ Red eye _ Severe and persistent itching of both eyes _ Mucoid eye discharge _ No visual reduction Signs _V/A is normal _ papillary reaction to hypertrophy on tarsal conjunctiva Treatment _ Cold compress _Vasoconstrictor-antihistamine like cromolyn sodium _ Topical steroid -Terracortril eye suspension Neonatal Conjunctivitis (Ophthalmia Neonatorum) Defn: is conjunctivitis in a newborn (in the first 28 days of life) Etiology Gonococcus and Chlamydia are the commonest cause of which gonococcal is most serious Symptoms - profuse thin to thick purulent eye discharge Sign - purulent eye discharge, eye lids are swollen - If cornea is involved, ulcer, scarring, lately cornea will shrink. Treatment - It is sight threatening condition that needs systemic antibiotic and close follow up in better ophthalmic center - Start with tetracycline eye ointment 3-4 times a day - Urgent referral to ophthalmic center for further evaluation and management 38 Prevention - The eye lids should be cleaned with saline swabs as soon as the head was born and before the infant‘s eyes opened. The diagnosis of such diseases need experienced ophthalmic worker, appropriate instruments and especial diagnostic tests and procedures. Their visual out come highly depends on the time interval between onset of the disease and initiation of treatment and subsequent close follow up. Symptoms - Painful red eye - Sudden reduction of vision - Rapid progressive visual impairment. Symptoms - Painful disorder-typically a constant severe boring pain that worsens at night or in the early morning hours and radiates to the face and 42 periorbital region. To give a general over view on the burden of blindness on global and country levels 2. To give a clear idea on the disease that have been launched by vision 2020 to control disease 4. The hope is that by the year 2020 most of the avoidable blindness in the world should be eliminated, so that everyone in the world except those with untreatable and unavoidable disease should have a visual acuity of 20/20 by the year 2020. The three main components (priorities) of Vision 2020 are 1-human resources development 2- Infrastructure and appropriate technology 3- Disease control (cataract, trachoma, onchocercaisis, childhood blindness, refractive error glaucoma and low vision). The result of these two factors means that the population aged over 60 years will double during the next 20 yrs from approximately 400 million now, to around 800 million in 2020. This increase in the elderly population will result in a greater number of the people with visual loss and blindness from cataract that will need eye services. A figure of 1000 new blind people from cataract per million populations per year is used for planning purpose in developing countries. Progress of the disease Some patient develops mature cataract only in a few months after a sign of opacity in the lens, others with early opacity may persist in the lens for many years without obvious progress at all. Signs - Reduced V/A - Whitish opacity seen through the pupil(see color plate3) Complication of unoperated cataract ™ Dislocation or sublaxation of lens ™ Glaucoma ™ Uveitis Operable cataract eyes The term is used to define a cataract where the patient and the surgeon agree to proceed with cataract surgery. It is a Greek word meaning ‘rough’ which describes the surface appearance of the conjunctiva. Trachoma tends to be found in dry rural areas, where lack of water and bad living conditions may facilitate the spread of the disease. Trachmatos inflammation becomes increasingly intense in children up to the age of six to eight years. Scars on the inside of the eye lids, caused by trachoma, can be found in children from the age of four years. Scarring is increasingly common in older children, but the serious complication of inturned eye lashes and corneal scarring do not usually appear before adult age. Trachoma in the community The severity of trachoma can vary from one community to another because of differences in the eases of spread of infection. Children are the main reservoir of Trachomatous infection, as they are commonly and heavily infected.

Coronary Veins Coronary veins drain the heart and generally parallel the large surface arteries (see Figure 19 generic lasix 100 mg amex. The great cardiac vein can be seen initially on the surface of the heart following the interventricular sulcus purchase lasix 40 mg overnight delivery, but it eventually flows along the coronary sulcus into the coronary sinus on the posterior surface trusted lasix 40 mg. The great cardiac vein initially parallels the anterior interventricular artery and drains the areas supplied by this vessel purchase lasix 100 mg online. It receives several major branches, including the posterior cardiac vein, the middle cardiac vein, and the small cardiac vein. The posterior cardiac vein parallels and drains the areas supplied by the marginal artery branch of the circumflex artery. The middle cardiac vein parallels and drains the areas supplied by the posterior interventricular artery. The small cardiac vein parallels the right coronary artery and drains the blood from the posterior surfaces of the right atrium and ventricle. The coronary sinus is a large, thin-walled vein on the posterior surface of the heart lying within the atrioventricular sulcus and emptying directly into the right atrium. The anterior cardiac veins parallel the small cardiac arteries and drain the anterior surface of the right ventricle. Unlike these other cardiac veins, it bypasses the coronary sinus and drains directly into the right atrium. It occurs when the buildup of plaque—a fatty material including cholesterol, connective tissue, white blood cells, and some smooth muscle cells—within the walls of the arteries obstructs the flow of blood and decreases the flexibility or compliance of the vessels. This condition is called atherosclerosis, a hardening of the arteries that involves the accumulation of plaque. As the coronary blood vessels become occluded, the flow of blood to the tissues will be restricted, a condition called ischemia that causes the cells to receive insufficient amounts of oxygen, called hypoxia. Some individuals with coronary artery disease report pain radiating from the chest called angina pectoris, but others remain asymptomatic. Such blockages can lead to decreased blood flow (ischemia) and insufficient oxygen (hypoxia) delivered to the cardiac tissues. The disease progresses slowly and often begins in children and can be seen as fatty “streaks” in the vessels. Well-documented risk factors include smoking, family history, hypertension, obesity, diabetes, high alcohol consumption, lack of exercise, stress, and hyperlipidemia or high circulating levels of lipids in the blood. Treatments may include medication, changes to diet and exercise, angioplasty with a balloon catheter, insertion of a stent, or coronary bypass procedure. A specialized catheter with an expandable tip is inserted into a superficial vessel, normally in the leg, and then directed to the site of the occlusion. At this point, the balloon is inflated to compress the plaque material and to open the vessel to increase blood flow. A stent consisting of a specialized mesh is typically inserted at the site of 846 Chapter 19 | The Cardiovascular System: The Heart occlusion to reinforce the weakened and damaged walls. This surgical procedure grafts a replacement vessel obtained from another, less vital portion of the body to bypass the occluded area. Nor does it seem advisable in patients with stable although diminished cardiac capacity since frequently loss of mental acuity occurs following the procedure. Long-term changes to behavior, emphasizing diet and exercise plus a medicine regime tailored to lower blood pressure, lower cholesterol and lipids, and reduce clotting are equally as effective. Not the least of these exceptional properties is its ability to initiate an electrical potential at a fixed rate that spreads rapidly from cell to cell to trigger the contractile mechanism. Even though cardiac muscle has autorhythmicity, heart rate is modulated by the endocrine and nervous systems. There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells. The myocardial contractile cells constitute the bulk (99 percent) of the cells in the atria and ventricles.
