Influenza occurs in seasonal epidemics and minor changes in the make-up of the influenza virus The pandemic in 1957 (“Asian flu”) caused by (known as antigenic drift) account for the changes in influenza A (H2N2) and 1968 (“Hong Kong flu”) the virus from one season to another purchase 1 mg tolterodine.

Influenza B viruses also cause epidemics and are largely restricted to A recent avian flu outbreak in chickens occurred Module 5 Page 137 in Hong Kong, Special Administrative Region of Methods of treatment China occurred in 1997-1998 and an experimental The antiviral drugs Amantadine and Rimantadine vaccine to avian flu is being developed.

Vaccine composition is tiredness and depression may persist for a few days changed annually to keep abreast of virus changes. Vaccination is recommended for elderly people, and people with chronic underlying conditions Complications such as diabetes and cardiopulmonary disease. Protection against the selected strain of as pneumonia, particularly in children, the elderly influenza lasts about one year. Pneumonia may be primary viral pneumonia or secondary bacterial For general infection control measures to prevent pneumonia.

Appendices 2, 3 and 4 Epidemiological summary Prevention of cross-infection as per Appendix 1 There are approximately 20–40 million cases of pertussis worldwide each year, 90% of them in Health education and health promotion developing countries; there are an estimated As for diphtheria 200 000–300 000 deaths each year. Manifestations Catarrhal stage • Fever and dry cough becoming worse at night • Vomiting with the cough • Infants often have a runny nose and sneezing • A particularly infectious stage of the illness Spasmodic stage (or paroxysmal stage) • Violent cough • The rapid expulsion of air followed by gasping Page 139 for breath through a narrowed glottis results in the characteristic high pitched “whoop” which gives the condition its name.

It occurs both as external or systemic infections that result in significant losses of hatchery-reared fish, particularly at warm summer temperatures (Pacha and Ordal 1970; Becker and Fujihara 1978). Epizootics of columnaris disease fre- quently occur in natural populations and high losses of fish may be observed. Wood (1974) describes strains of high and low virulence; highly virulent forms attack gill tissue and the latter strains are primarily responsible for cutaneous infections. Some disagreements still exist concerning proper taxonomic place- ment of this organism (Snieszko and Bullock 1976). These characteristic “saddleback” lesions may progress until skin erosion exposes underlying muscle tissue. These lesions may become yellow and cratered and are often prominent in the mouth and head regions (Wood 1979). Systemic infections due to less virulent strains may occur with no apparent external signs. Frequently, material scraped from such lesions and examined under phase contrast microscopy in a wet mount will reveal the presence of unique characteristic “haystack” colonies that are of diagnostic significance.

Treatment can be problematic because the recommended duration for hyp- notic drug use is 4 weeks. The time limitation advocated for hypnotic drug use has been set to prevent habituation and the withdrawal symptoms after long-term use. Persons with insomnia have difficulty getting to sleep and staying asleep, and they wake unrefreshed. Acute stress and environmen- tal disturbances are the most common causes of transient and short-term insomnia. Chronic insomnia is often associated with medical conditions, psychiatric problems such as depression, or persistent psychophysiologic disorders such as inadequate sleep hygiene. This involves creating external and internal environments that are conducive to sleep. Except for a physiologic mid-afternoon dip in alertness, the circadian rhythm of sleepiness and alertness promotes a daily cycle of nighttime sleep and daytime alertness. Normal sleep consists of four to six behaviorally and electroencephalo- graphically defined cycles. It initially reduces sleep latency and decreases arousals but then causes increased waking in the second half of the night. Caffeine may reduce sleep latency, but it fragments sleep, causing sleep disruption in the latter part of the night. Milk is a rich source of tryptophan and nicotinic acid, one of the B group of vitamins that influences the conversion of tryptophan to serotonin. The belief that drinking a warm glass of milk before going to bed will help one sleep is biochemically plausible. Single low doses of melatonin, provided that they mimic the nocturnal phys- iologic concentration of this hormone, exert immediate sleep-inducing effects. L-Tryptophan is the amino acid precursor to serotonin, the neurotrans- mitter thought to induce sleep. A dose of 1 to 2 g of L-tryptophan has been reported to halve sleep latency and decrease waking time. The sleep patterns of insomniacs taking tryptophan more closely Chapter 32 / Insomnia 341 resemble those of normal sleepers than those of untreated insomniacs or per- sons taking sleeping tablets. In fact, the only change noted in the architecture of tryptophan-assisted sleep is an increase in duration of the third and fourth stages of slow-wave sleep. The immediate precursor of sero- tonin, 5-hydroxytryptophan (10 mg), is currently being used as a sleep aid, a treatment for depression, and a weight loss aid. When tryptophan is taken with vitamin B6 (50 mg) and niacinamide (500 mg), the conversion of tryptophan to serotonin is favored. Controlled clinical trials suggest that deficiency of potassium or thiamine may contribute to insomnia. A lignan, hydroxypinoresinol, with the ability to bind to benzodiazepine receptors is also present. The considerable variation in the composition and content of valerian and the instability of some of its constituents pose serious problems for standardization, but the range of components that contribute to its over- all activity suggest that it may correct a variety of underlying conditions that benefit from a general sedative or tranquilizing effect. Results of clinical trials indicate that 400 to 900 mg of valerian extract taken at bedtime improves sleep quality, decreases sleep latency, and reduces the number of night awakenings. A randomized, double-blind, placebo-controlled, crossover study with multiple dosages of valerian demonstrated that slow-wave sleep latency was reduced after administration of valerian over several days. The researchers concluded that valerian could be recom- mended for the treatment of patients with mild psychophysiologic insomnia. Another randomized, controlled, double-blind trial indicated that neither single nor repeated evening administration of 600 mg of native valerian root extract had any relevant adverse effect on reaction time, alertness, and con- centration the morning after.
