Substances with insufficient human data were also considered as possible fragrance allergens erectile dysfunction pump implant purchase tadalis sx 20mg. Allergens of special concern are substances where between 100 and 1 erectile dysfunction recreational drugs purchase 20mg tadalis sx,000 cases (+++) and more than 1 impotence in a sentence tadalis sx 20mg sale,000 (++++) have been published cialis erectile dysfunction wiki tadalis sx 20mg overnight delivery. Nevertheless erectile dysfunction and diabetes treatment 20 mg tadalis sx mastercard, following a precautionary approach erectile dysfunction hypertension medications discount tadalis sx 20 mg overnight delivery, the four substances/substance mixtures should be treated as likely contact allergens. While available clinical evidence regarding this set of substances is listed in Annex I to this opinion, these substances have not further been evaluated. Of those, 12 chemicals and eight natural extracts are considered of special concern as they have given rise to at least 100 reported cases (listed in Table 13-5). These substances pose a particularly high risk of sensitisation to the consumer and are further considered in the answer of question 2. The number of cases is only those reported in scientific publications, and therefore the actual number of cases is severely under-estimated. Information on the presence of all the substances given in Table 13-1, Table 13-2 and Table 13-3 in cosmetic products is important in order to enable aimed testing of patients with contact dermatitis and to diagnose fragrance allergy without delay. Further, this information is important to the sensitised consumer as it will enable them to avoid cosmetic products, which they may not tolerate. Substances given in Table 13-4 are possible contact allergens and further data are required to judge if these are contact allergens in humans and give rise to contact allergy in consumers. A comprehensive list of established contact allergens in humans is given in Table 13-1. Additionally, limited human and/or animal evidence together with structure activity relationship analysis suggests that other fragrance ingredients may be a cause of concern with regard to their potential of causing contact allergy in humans. Ingredient listing is important in clinical practice for the management of patients who are allergic to one or more of the listed fragrance chemicals. It is also important for the patients in order to avoid future exposure to fragrance contact allergens which they may not tolerate. Important indicative, but not exhaustive, examples include isoeugenol and its esters, geraniol and its esters, eugenol and its esters, and linalool and its esters. Important indicative examples include limonene, linalool, linalyl acetate, geraniol, geranial, alpha-terpinene, eugenol, isoeugenol and cinnamyl alcohol. Dose-response relationships exist between exposure to contact allergens and the proportion of consumers who will become sensitised to an allergen. For a number of recognised contact allergens in man, dose-elicitation studies on sensitised individuals are available. These studies indicate that it is in principle possible to derive exposure levels that the majority of sensitised individuals will tolerate. Among the established chemical fragrance allergens, 12 were identified as posing a high risk of sensitisation to the consumer (Table 13-5), i. For these substances, limitation of exposure would help to protect sensitised consumers from developing allergic contact dermatitis. In addition, such a study has also been performed on chloroatranol, a potent allergen in Evernia prunastri and Evernia furfuracea. These studies, however, are not adequate to derive safe thresholds for the individual substances directly from the data. If no such data are available, for substances posing a high risk to the consumer (like the 12 listed in Table 13-5), the use of a general threshold may be considered. However, some strong and extreme sensitisers may require lower individual thresholds. As an example, chloroatranol, present in the natural product Evernia prunastri and in Evernia furfuracea, has been shown to have an elicitation 2 threshold of 0. On the other hand, for very weak sensitisers, this generic threshold may be too conservative. In cases where specific data of sufficient quality on threshold levels for a particular allergen are available, these data should be used to set an individual safe threshold. However, when such quality data are not available and a substance has been identified to pose a high risk of sensitisation to the consumer, the general threshold limit (100 ppm in cosmetic products) can be applied. In total, reports of more than 1500 cases have been published in the scientific literature (see chapter 7. Chloroatranol and atranol are the main allergenic components of Evernia prunastri and Evernia furfuracea. Conclusions Question 2 There are two components to the safety of fragrance ingredients in terms of contact allergy. First, the need to eliminate or reduce induction of contact allergy (primary prevention), which, when it occurs, is life long. Secondly, the need to eliminate or reduce elicitation reactions (secondary prevention) on the skin of those individuals who are already sensitised. Human dose elicitation experiments have hithereto been performed only for a very small number of substances. It is unlikely that more of these studies will be performed due to experimental and subject recruitment difficulties. For individual substances, no levels that could be considered safe for the majority of consumers could be established from the available data. The dose elicitation studies available indicate that a general level of exposure of up to 0. Such a thresholds based on elicitation levels in sensitised individuals will be sufficiently low to protect both sensitised individuals as well as most of the non-sensitised consumers from developing contact allergy. It was not possible to provide a safe threshold for natural extracts of concern, as no specific investigations exist and the model providing the general threshold (0. Hence, this threshold does not remove the necessity for providing information to the consumer concerning the presence of the fragrance substance in cosmetics. The persistently high frequency of contact allergy to Evernia prunastri and Evernia furfuracea noted in eczema patients does point to a persisting problem with exposure to allergenic constituents. Many fragrance substances can act as prehaptens or prohaptens, forming potent allergens by abiotic and/or metabolic activation, and thus increasing the risk of sensitisation. Experimental and clinical studies have shown that there are fragrance substances that act as prehaptens, i. Limonene, linalool, linalyl acetate, alpha-terpinene and geraniol have all been identified as prehaptens. These fragrance substances are common in scented cosmetics as well as in household products. The clinical studies show that the exposure to allergens formed due to autoxidation causes significant contact allergy in consumers. Patch testing with oxidised limonene and oxidised linalool shows that these substances rank among the most common contact allergens. It is also important to investigate the stability of the primary oxidation products (the hydroperoxides) formed from various structures of fragrance compounds. The stability of these compounds can have great impact on the sensitisation potency of the oxidised compound as they are strong sensitisers. However, the secondary oxidation products (aldehydes and epoxides) can also be important sensitisers depending on the overall structure of the compound as was demonstrated for oxidised geraniol. Air oxidation of prehaptens can be prevented to a certain extent by measures during handling and storage of the ingredients and final products to avoid air exposure, and/or by addition of suitable antioxidants. The autoxidation rate depends not only on the compound itself, but also on its purity. This is the case for alpha-terpinene which is described as the antioxidant in tea tree oil (Rudback J, Karlberg A-T et al, Chem Res Toxicol, manuscript submitted). As antioxidants are now frequently used at elevated concentrations in scented products due to a growing awareness of the problem of autoxidation, there is a risk that sensitisation caused by the antioxidants will rise. It should be noted that, to decrease the risk for sensitisation in the population, the possibility to reduce the sensitisation potency by preventing autoxidation is important also for a direct acting hapten or prohapten, if a further activation by air oxidation to more allergenic compounds has been shown. Based on the clinical data, oxidised limonene and oxidised linalool are allergens of high concern (Table 13-5) which pose a high risk of sensitisation to the consumer. For these substances the presence of the oxidised fraction represented by the peroxide content should not be higher than 10 ppm. Compounds that are bioactivated by metabolising enzymes to haptens are referred to as prohaptens. Established prohaptens of clinical importance are cinnamyl alcohol, geranial, geraniol, eugenol, isoeugenol and alpha-terpinene. Fragrance Activation by air Bioactivation Bioactivation substance oxidation (oxidation) (hydrolysis) Cinnamyl alcohol x Eugenol x Eugenyl acetate x x Geranial x x Geraniol x x Geranyl acetate x x x Isoeugenol x Isoeugenol acetate x x Limonene x Linalool x Linalyl acetate x alpha-terpinene. An increased complexity in the cross-reactivity pattern is obtained when a compound could act both as a prehapten and a prophapten. In case derivatives of a fragrance substance are used, it must be taken into account that the derivative could be transformed into the parent or a cross-reacting compound. In particular, hydrolysis of esters to the corresponding alcohols can cause cross-reactions. Acetate esters of eugenol, isoeugenol and geraniol are frequently used in cosmetics. To be able to predict the sensitisation potency of prohaptens, steps of bioactivation have to be included in the predictive tests. Activation of individual compounds to various haptens increases the risks of cross reactivity between chemicals and also causes difficulties in prediction of these risks. Prediction of risks requires sound application of theoretical principles in combination with well designed experimental studies. Conclusions Question 3 Many fragrance substances can act as prehaptens or prohaptens, forming potent allergens by abiotic and/or metabolic activation. Fragrances with published data showing the formation of sensitising compounds by autoxidation, bioactivation or both are the following (see also Table 13-6). Fragrance substances of clinical importance known to be prehaptens and to form sensitising compounds by air oxidation are limonene, linalool, and linalyl acetate. Fragrance substances of clinical importance known to be prohaptens and to form sensitising compounds by metabolic transformation are cinnamyl alcohol, eugenol, isoeugenol and isoeugenyl acetate. Fragrance substances of clinical importance with published data known to be both prehaptens and prohaptens and to form sensitising compounds by air oxidation (prehaptens) and by metabolic transformation are geraniol and alpha terpinene. A fragrance substance that sensitises without activation but forms more potent sensitising compounds by air oxidation and also by metabolic transformation is geranial (one isomer of citral). In the case of prehaptens, it is possible to prevent activation outside the body to a certain extent by different measures. The possibility to reduce the sensitisation potency by preventing air oxidation is important also for a direct acting hapten or prohapten, if a further activation by air oxidation to more allergenic compounds has been shown. In the case of prohaptens, the possibility to become activated is inherent to the molecule and activation cannot be avoided by extrinsic measures. Activation processes increase the risk for cross-reactivity between fragrance substances. Cross-reactivity has been shown for certain alcohols and their corresponding aldehydes, i. Esters of important contact allergens that can be activated by hydrolysis in the skin are isoeugenyl acetate, eugenyl acetate and geranyl acetate which all are known to be used as fragrance ingredients. The substances presented above are based on current knowledge and should be seen as indicative and illustrative of the general problem.

Hemophilic Arthropathy (I-14) Definition Bouts of acute, constant, nagging, burning, bursting, and incapacitating pain or chronic, aching, nagging, gnawing, and grating pain occurring in patients with congenital blood coagulation factor deficiencies and secondary to hemarthrosis. As the first joints become progressively affected, other remaining articular and muscle areas are involved with changes of disuse atrophy or progressive hemorrhagic episodes. Main Features Prevalence: hemophilic joint hemorrhages occur in severely and moderately affected male hemophiliacs. Acute hemarthrosis occurs most commonly in the juvenile in association with minor trauma. In the adult, spontaneous hemorrhages and pain occur in association also with minor or severe trauma. Characteristically the acute pain is associated with such hemarthrosis, which is relieved by replacement therapy and rest of the affected limb. A reactive synovitis results from repeated hemarthroses, which may be simply spontaneous small recurrent hemorrhages. The pain associated with them is extremely difficult to treat because of the underlying inflammatory reaction. Time Course: the acute pain is marked by fullness and stiffness and constant nagging, burning, or bursting qualities. It is incapacitating and will cause severe pain for at least a week depending upon the degree of intra-capsular swelling and pressure. Chronic pain is often a dull ache, worse with movement, but can be debilitating, gnawing, and grating. At the stage of destructive joint changes the chronic pain is unremitting and relieved mainly by rest and analgesics. These syndromes are exacerbated by accompanying joint and muscle degeneration due to lack of mobility rather than repeated hemorrhages. Associated Symptoms Depressive or passive/aggressive symptoms often accompany hemorrhages and are secondary to the extent of pain or to the realization of vulnerability to hemorrhage, which is beyond the control of the hemophiliac. Numerous psychosomatic complaints are associated with the chronic and acute pain of chronic synovitis, arthritis, and hemarthrosis. Marked limitation of joint movement often with signs of adjacent involvement of muscle groups due to disuse atrophy. Chronic Joint Degeneration: Severe bony remodeling with decrease in joint movement, adjacent muscular atrophy with subsequent fixation of the joint and loss of effective use. Laboratory Findings X-rays with the large hemarthrosis show little except for soft tissue swelling. In reactive synovitis there is often evidence of osteoporosis accompanied by overgrowth of the epiphyses but not evidence of joint destruction. In chronic arthropathy there is cartilage destruction and narrowing of the joint space. Cysts, rarefactions, subcondylar cysts, and an overgrowth of the epiphysis are noted. This progresses through to fibrous joint contracture, loss of joint space, extensive enlargement of the epiphysis, and substantial disorganization of the joint structures. The articular cartilage shows extensive degeneration with fibrillation and eburnated bone ends. Usual Course Until the availability of therapy with blood clotting factor concentrate, there was an inexorable deterioration of the affected joints following the initial repeated spontaneous hemarthroses in the severely affected individual. This joint deterioration was associated with pain as described in the section regarding time course. The introduction of concentrated clotting factor transfusions has avoided the consequence of repeated acute severe hemarthroses. However, it is by no means certain whether the pain pattern of chronic synovitis and arthritis can be avoided or merely delayed using such therapy. Therapy blood clotting factor concentrate is available on a regular basis only in North America and Europe at this time. Relief Acute Hemarthrosis: Adequate intravenous replacement with appropriate coagulation factors with subsequent graded exercise and physiotherapy will provide good relief. Aspiration of the joint will be necessary under coagulation factor cover if there is excessive intracapsular pressure. Reactive and Chronic Hemarthrosis: Prophylactic factor replacement is required in association with analgesics and carefully selected antiinflammatory agents. Pain control using analgesics and transcutaneous nerve stimulation is also useful, and physiotherapy is of considerable assistance in managing both symptoms and signs. Synovectomy may be of use for the control of pain secondary to the recurrent bleeding. Chronic Destructive Arthropathy: Replacement therapy is of little assistance in relieving pain and disability. Carefully selected antiinflammatory agents and rest are the major therapies of use. Complications Analgesic abuse is a common problem in hemophilia due to the acute and chronic pain syndromes associated with hemophilic arthropathy. This problem can be avoided in the younger age group by not using narcotic analgesics for chronic pain management and relying upon principles of comprehensive hemophilia care. These include regular physiotherapy, exercise, and making full use of available social and professional opportunities. Social and Physical Disability Severe crippling and physical disability, with prolonged school and work absences, have traditionally been associated with this form of arthropathy. Consequently, affected individuals have not been able to achieve satisfactory school and job schedules. It is considered that the higher suicide rate is related not only to the family and psychosocial aspects of the disease but also to the chronic pain syndromes that these individuals experience. Phase one involves an early synovial soft tissue reaction caused by intraarticular bleeding. Synovial hypertrophy with hemosiderin deposition and mild perivascular inflammation are present. Cartilage degeneration and joint degeneration similar to that seen in osteoarthritis and rheumatoid arthritis is seen in the second-phase joint. Associated with this type of phase two change is synovial thickening and hyperplasia which falls into numerous folds and clusters of villi. Summary of Essential Features and Diagnostic Criteria Acute and chronic pain as the result of acute hemarthrosis with chronic synovial cartilaginous and bony degeneration is exacerbated by spontaneous and trauma-related hemorrhage. Diagnostic Criteria Pain associated with hemophiliac arthropathy must satisfy both 1 and 2. Spontaneous intracapsular hemorrhages in an individual with an inherited hemostatic defect. Burns (I-15) Definition Acute and severe pain at first, following bums, later continuous with exacerbations, gradually declining. Any age can be affected, but the highest incidence (18%) is between 20 and 29 years. Children are the next largest group, with 30% of these being in the 1-2 year age group. It is frequently described as throbbing, smarting, and stinging, and marked exacerbations of stabbing pain occur with any movement or procedure. Thus, it is particularly intense where there are skin creases or flexures or where pressure is applied, such as palms, soles, genitalia, ears, or resting surfaces. Despite the destruction of all cutaneous nerve endings, full thickness bums are often painful with a quality described as deep, dull, or aching. Intensity and Duration: the pain tends to diminish in intensity as healing takes place. In addition, the quality of the pain changes, and at one to two weeks after the bum is usually described as sore, aching, tender, tiring, and tight. In addition, frequent surgery is often necessary, with an accompanying increase in pain. Relief may be promoted by the use of opioid premedication prior to procedures, time contingent analgesics, inhalational analgesia during procedures, ensuring that the burnt areas never dry out, protecting the bum with creams, and achieving skin cover by some means as soon as possible. Complications If healing occurs, it is unusual to have persistent pain unless deep structures (muscle, bones, major nerves) are involved. Cellulitis in burnt areas or donor sites may lead to a marked increase in the severity of pain. Social and Physical Disability this is most frequent where the bum is extensive, and such cases often require sustained treatment and prolonged hospitalization. Pathology Loss of skin integrity with consequent loss of fluid and thermoregulation and an increased likelihood of infection. A partial thickness burn involves epidermis and dermis at varying depths, and a full thickness burn involves epidermis, dermis, and at times deeper tissues. Electrical burns may cause considerable damage to deeper tissues by direct effect and by occlusion of blood vessels. The severity of damage is related to the temperature to which the area was exposed, the duration of exposure, and the thickness of the skin involved. Summary of Essential Features and Diagnostic Criteria Pain with the appropriate time course following burns. Differential Diagnosis Possibly hysterical conversion pain or pain of psychological origin may prolong or exacerbate the original effects of the injury. Start: gradual emergence intermittent at first, as mild diffuse ache or unpleasant feeling, increasing to a definite pain part of the time. Pain Quality: dull ache, usually does not throb; severe during exacerbations, often or almost always with throbbing. Occurrence and Duration: most days per week, usually every day for most of the day. Precipitants and Exacerbating Factors: emotional stress, anxiety and depression, physical exercise, alcohol. Associated Symptoms Many patients have anxiety, depression, irritability, or more than one of these combined. Signs Muscle tenderness occurs but may also be found in other conditions and in normal individuals. Relief Resolution or treatment of emotional problems, anxiety, or depression often diminishes symptoms. Anxiolytics may help but should be avoided since some patients become depressed and others develop dependence. Differential Diagnosis From delusional and conversion pains; from muscle spasm provoked by local disease; and from other causes of dysfunction in particular regions. Main Features Prevalence: rare; estimated to be present in less than 2% of patients with chronic pain without lesions. Age of Onset: not apparently reported in children; onset in late adolescence or at any time in adult life. Pain Quality: may be sensory or affective or both, not necessarily bizarre; essential characteristic is attribution of the pain by the patient to a specific delusional cause. Associated Symptoms and Modifying Factors May be exacerbated by psychological stress, relieved by treatment causing remission of illness. Complications In accordance with causal condition; usually lasts for a few weeks in manic-depressive or schizo-affective psychoses, may be sustained for months or years in established schizophrenia if resistant to treatment. Occasionally chronic pain without any formal delusions remits to be succeeded by a paranoid or schizophrenic psychosis. Social and Physical Disabilities In accordance with the mental state and its consequences. Essential Features Those required for diagnosis are pain, without a lesion or overt physical mechanism and founded upon a delusional or hallucinatory state. Differential Diagnosis From undisclosed or missed lesions in psychotic patients, or migraine, giving rise to delusional misinterpretations; from tension headaches; from hysterical, hypochondriacal, or conversion states. X9a Note: X = to be completed individually according to circumstances in each case. Site May be symmetrical; if lateralized, possibly more often on the left precordium, genitals; may be at any single point over the cranium or face, can involve tongue or oral cavity or any other body region. Frequency increases from general practice populations to specialized headache or pain clinics or psychiatric departments. Estimates of 11% and 43% have been found in psychiatric departments, depending on the sample. Sex Ratio: estimated female to male ratio 2:1 or greater-particularly if multiple complaints occur. Onset: may be at any time from childhood onward but most often in late adolescence. Pain Quality: described mostly in simple sensory terms, but complex or affective descriptions occur in some cases. Time Pattern: Pain is usually continuous throughout most of the waking hours but fluctuates somewhat in intensity, does not wake the patient from sleep. Associated Symptoms Loss of function without a physical basis (anesthesia, paralyses, etc. There may be frequent visits to physicians to obtain relief despite medical reassurance, or excessive use of analgesics as well as other psychotropic drugs for complaints of depression, neither type of remedy proving effective.

Hepatitis B is a serious and common infectious disease of the liver, affecting millions of people throughout 6, 10, 15, 23, 31 the world. Infection occurs very often in early childhood when it is asymptomatic and often leads to the chronic carrier state. Of 6, 15, 23, 38, 51 these, about 350 million remain infected chronically and become carriers of the virus. The virus interferes with the functions of the liver while replicating in hepatocytes. The immune system is then activated to produce a specific reaction to combat and possibly eradicate the infectious agent. One should not judge by appearance: most infected people look perfectly healthy and have no symptoms of disease, yet may be highly infectious. Some break in this barrier, which can be 31 minimal and insignificant, is required for transmission. Sexual intercourse with multiple partners or with persons who have multiple partners can be dangerous. Blood is infective many weeks before the onset of the first symptoms and throughout the acute phase of the disease. In countries such as China, Senegal, Thailand, infection rates are very high in infants, and continue through early childhood. In other countries such as Panama, Papua New Guinea, Solomon Islands, Greenland, and in populations such as 15 Alaskan Indians, infection rates in infants are relatively low and increase rapidly during early childhood. Low endemicity areas include North America, Western and Northern Europe, Australia, and parts of South 15, America. Of these children, 25% will die later from chronic liver 15 disease or liver cancer. Hepatitis B is a viral disease, and as such, antibiotics are of no value in the treatment of the infection. The use of adrenocorticosteroids in the management of acute, uncomplicated hepatitis B is not indicated because they have no effect on the resolution of the underlying disease process, and may increase the rate of relapse. Early treatment of acute hepatitis B with steroids may result in the development of persistent infection. Therapy for acute hepatitis B should be supportive and aimed at maintaining comfort and adequate 23 nutritional balance. Specific antiviral drugs such as lamivudine, a second generation nucleoside analogue, are available, and others are under development, but these drugs have not been evaluated for the treatment of acute hepatitis B. Hepadnaviruses show narrow host ranges, growing only in species close to the natural host, like gibbons, African green monkeys, rhesus monkeys, 15, 30, 31 and woolly monkeys. Hepatocytes infected in vivo by hepadnaviruses produce an excess of noninfectious viral lipoprotein 15 particles composed of envelope proteins. The surface antigen is generally produced in vast excess, and is found in the blood of infected individuals in the form of filamentous and spherical particles. Filamentous particles are identical to the virion "tails" they vary in length and have a mean diameter of about 22nm. A group of hepatitis B virions (right) and enlargements of the two exposed cores (indicated by arrows). A number of candidate receptors have been identified, including the transferrin receptor, the asialoglycoprotien receptor molecule, and human liver endonexin. These transcripts are polyadenylated and transported to the cytoplasm, where they are translated into the viral nucleocapsid and precore antigen (C, pre-C), polymerase (P), envelope L (large), M (medium), S 6, 10, 23, 31 (small)), and transcriptional transactivating proteins (X). The new, mature, viral nucleocapsids can then follow two different intracellular pathways, one of which leads to the formation and secretion of new virions, whereas the other leads to amplification of the viral 10, 23 genome inside the cell nucleus. Nuclear localisation signals on the polymerase mediate the transport of covalently 6, 10 linked viral genome through the nuclear pore. Tubular, filamentous forms of various lengths, but with a diameter comparable to that of the small particles, 15, 31 are also observed. Within the sphere is an electron-dense inner core or nucleocapsid with a diameter of 27 nm. The envelope can be removed with nonionic detergents, liberating the inner core, the nucleocapsid of 27 nm. The 22 nm spheres and filaments lack nucleic acid altogether and hence are noninfectious. A virion-associated polymerase can repair this gap and generate a fully duplex genome. Two other proteins share the C-terminal S domain, but differ by length and structure of their N-terminal (pre-S) extensions. The large L protein (39 kD) contains the pre-S1, the pre-S2 region and the S region, and the medium M protein (31 kD) contains the pre-S2 and the S region only. The L and M proteins are expressed at levels of about 5-15% and 1-2% compared with S 31 protein. In addition, the M protein contains an N-linked oligosaccharide on its pre-S2-specific domain, and the L protein carries a myristic acid group in amide linkage to its amino-terminal glycine residue. While the function of M protein is still 31 obscure, L proteins play a role in viral assembly and infectivity. Subviral 22 nm particles are composed predominantly of S proteins, with variable amounts of M proteins and few or no L proteins. L proteins carry the receptor recognition domain, which allows efficient binding to cell surface receptors. The polymerase protein is quite immunogenic during both 6 acute and chronic infection. Boxes denote viral coding regions, with arrows indicating direction of translation. This implies that the integration event(s) preceded the clonal expansion of the cells. There is no similarity in the pattern of integration between different tumours, and variation is seen both in 52 the integration site(s) and in the number of copies or partial copies of the viral genome.

Multiple com pression fractures of the vertebrae result in skeletal deformity (kyphosis) erectile dysfunction products discount 20mg tadalis sx with amex. Patients at risk include postmenopausal women and small framed erectile dysfunction venous leak cheap tadalis sx uk, nonobese Caucasian women. Risk factors include inadequate nutrition, inadequate vita min D and calcium, and lifestyle choices (eg, smoking, caf feine intake, and alcohol consumption); genetics; and lack of physical activity. Age-related bone loss begins soon after peak bone mass is achieved (in the fourth decade). Withdrawal of estrogens at menopause or oophorectomy causes decreased cal citonin and accelerated bone resorption, which continues dur ing menopausal years. Secondary osteoporosis is the result of medications or other conditions and diseases that affect bone metabolism. Speci c disease states (eg, celiac disease, hypog onadism) and medications (eg, corticosteroids, antiseizure medications) that place patients at risk need to be identi ed and therapies instituted to reverse the development of osteo porosis. Gerontologic Considerations Elderly people fall frequently as a result of environmental haz ards, neuromuscular disorders, diminished senses and cardio vascular responses, and responses to medications. The patient and family need to be included in planning for care and pre ventive management regimens. For example, the home envi ronment should be assessed for safety and elimination of Osteoporosis 475 potential hazards (eg, scatter rugs, cluttered rooms and stair wells, toys on the oor, pets underfoot). A safe environment can then be created (eg, well-lighted staircases with secure hand rails, grab bars in the bathroom, properly tting footwear). Patients who have not responded to rst-line approaches to the treatment of vertebral com pression fracture can be considered for percutaneous verte broplasty or kyphoplasty (injection of polymethylmethacry O late bone cement into the fractured vertebra, followed by in ation of a pressurized balloon to restore the shape of the affected vertebra). Otitis Media, Acute Acute otitis media is an acute infection of the middle ear, usu ally lasting less than 6 weeks. The pathogens that cause acute otitis media are usually Streptococcus pneumoniae, Haemophilus in uenzae, and Moraxella catarrhalis, which enter the middle ear after eustachian tube dysfunction caused by obstruction related to upper respiratory infections, in ammation of sur rounding structures (eg, rhinosinusitis, adenoid hypertrophy), or allergic reactions (eg, allergic rhinitis). Bacteria can enter the eustachian tube from contaminated secretions in the 478 Otitis Media, Acute nasopharynx and the middle ear from a tympanic membrane perforation. Myringotomy (Tympanotomy) If mild cases of otitis media are treated effectively, a myringo tomy may not be necessary. If it is, an incision is made into the tympanic membrane to relieve pressure and to drain serous or purulent uid from the middle ear. If episodes of acute otitis media recur and there is no contraindication, a ventilating, or pressure-equalizing, tube may be inserted. Otitis Media, Chronic 479 Otitis Media, Chronic Chronic otitis media results from repeated episodes of acute otitis media, causing irreversible tissue pathology and per sistent perforation of the tympanic membrane. Chronic infections of the middle ear cause damage to the tympanic membrane, can destroy the ossicles, and can involve the mastoid. If untreated, the cholesteatoma continues to grow and destroys structures of the temporal bone, possibly causing damage to the facial nerve and horizontal canal and destruction of other surrounding structures. O P Pancreatitis, Acute Pancreatitis (in ammation of the pancreas) is a serious disor der that can range in severity from a relatively mild, self limiting disorder to a rapidly fatal disease that does not respond to any treatment. Acute pancreatitis is commonly described as an autodiges tion of the pancreas by the exocrine enzymes it produces, prin cipally trypsin. Eighty percent of patients with acute pancre atitis have biliary tract disease or a history of long-term alcohol abuse. Other less common causes of pancreatitis include bacterial or viral infection, with pancreatitis occa sionally developing as a complication of mumps virus. Many disease processes and conditions have been associated with an increased incidence of pancreatitis, including surgery on or near the pancreas, medications, hypercalcemia, and hyperlipi demia. Up to 10% of cases are idiopathic, and there is a small incidence of hereditary pancreatitis. Mortality is high because of shock, anoxia, hypotension, or uid and electrolyte imbalances. Attacks of acute pancreatitis may result in complete recovery, may recur without perma nent damage, or may progress to chronic pancreatitis. Serum amylase and lipase levels are most indicative (ele vated within 24 hours; amylase returns to normal within 48 to 72 hours; lipase remains elevated for longer period). Gerontologic Considerations the mortality from acute pancreatitis increases with advanc ing age. Patterns of complications change with age (eg, the incidence of multiple organ failure increases with age). Close monitoring of major organ function (lungs and kidneys) is essential, and aggressive treatment is necessary to reduce mor tality in the elderly. Medical Management: Acute Phase During the acute phase, management is symptomatic and directed toward preventing or treating complications. Current recommenda tion for pain management is parenteral opioids, including morphine, hydromorphone, or fentanyl via patient controlled analgesia or bolus. Pancreatitis, Chronic Chronic pancreatitis is an in ammatory disorder character ized by progressive anatomic and functional destruction of the pancreas. The end result is obstruc tion of the pancreatic and common bile ducts and duode num. In addition, there is atrophy of the epithelium of the ducts, in ammation, and destruction of the secreting cells of the pancreas. Alcohol consumption in Western societies and malnutrition worldwide are the major causes. The incidence of pancreatitis among alcoholics is 50 times the rate in the nondrinking population. Pathophysiology Long-term alcohol consumption causes hypersecretion of pro P tein in pancreatic secretions, resulting in protein plugs and calculi within the pancreatic ducts. Damage is more severe in patients with diets low in protein and very high or very low in fat. Because heavy drinkers usually smoke, it is dif cult to separate the effects of the alcohol abuse and smoking. Medical Management Treatment is directed toward preventing and managing acute attacks, relieving pain and discomfort, and managing exocrine and endocrine insuf ciency of pancreatitis. Patient and family are taught the hazard of severe hypoglycemia related to alcohol use. The cause of the disease is mostly unknown but research suggests several causative factors (eg, genetics, ather osclerosis, viral infections, head trauma). The disease usually rst appears in the fth decade of life and is the fourth most common neurodegenerative disease. The loss of dopamine stores in this area of the brain results in more excitatory neurotransmitters than inhibitory neurotransmitters, leading to an imbalance that affects vol untary movement. Cellular degeneration causes impairment of the extrapyramidal tracts that control semiautomatic func tions and coordinated movements; motor cells of the motor cortex and the pyramidal tracts are not affected. Medical Management Goal of treatment is to control symptoms and maintain func tional independence; no approach prevents disease progression. Observe the patient for quality of speech, loss of facial expression, swallowing de cits (drooling, poor head control, coughing), tremors, slowness of movement, weakness, forward posture, rigidity, evidence of mental slowness, and confusion. Teach patient to walk erect, watch the horizon, use a wide-based gait, swing arms with walking, walk heel-toe, and practice marching to music. Also encourage breathing exercises while walking and frequent rest periods to prevent fatigue or frustration.
