The procurement of non-formulary medications or the procurement of formulary medications used outside of formulary restrictions is considered an unauthorized procurement. Revisions or changes from the previous year are highlighted in Yellow throughout the document. Periodically, medications are reassessed and extensively reviewed for inclusion, exclusion, or restrictions in the formulary as applicable per current evidence-based practices and security concerns. It is expected that nonformulary use criteria will be thoroughly addressed point by point and that all non-formulary justifications/criteria are met. Institution Chief Pharmacists are expected to review all medication orders for formulary compliance. This will include reviewing all non-formulary requests for completeness and appropriate justification, and, if applicable, commenting on information provided by the prescriber regarding non-formulary use criteria. The pharmacist is also expected to provide pertinent information regarding patient compliance for formulary agents, drug cost information, and other comments as they pertain to the request. All such orders/recommendations are still subject to the non-formulary approval process. It is expected that all institution inventories and ordering procedures will be conducive to acceptable inventory practices. This may be prompted by consistent failure of the institution staff to appropriately initiate or complete all elements of the non-formulary request, particularly the required supporting documentation. Continuity of Care Provision: There are times when inmates are processed into a facility after normal working hours, weekends, and holidays. This four day allowance is to only be utilized for urgent continuity of care purposes, and not for initiating routine/non-emergency non-formulary medications without appropriate approval. This provision is not a substitute for adequate follow up, monitoring, and initiation of non-formulary medications for patients maintained within the facility for chronic ongoing conditions. Medication orders that do not meet the above continuity of care elements should not be written, entered into the pharmacy software system, or dispensed prior to the appropriate non-formulary approval. Health services staff will document the encounter in the Medication Administration Record daily. The inmate should be counseled regarding the potential consequences and adverse actions that may occur if tampering is evident or the product is lost or manipulated. There are some medications that are designated as directly observed therapy only for certain indications (see page 10). Subsequent medication orders for this drug must also include the signature of a physician. This responsibility is deferred to the local level due to the varying missions of our institutions.

It is important to remember that antihistamines should be stopped for at least 3 days before these are undertaken medicine 257 eldepryl 5 mg for sale. The history should include details of the events surrounding the onset of the eruption medicine for sore throat purchase eldepryl 5 mg online. Careful attention should be paid to drugs symptoms pulmonary embolism purchase 5mg eldepryl with mastercard, remembering that self-prescribed ones can also cause urticaria medicine norco purchase eldepryl 5 mg with mastercard. Over-the-counter medications (such as aspirin and herbal remedies) and medications given by other routes (Table 8. If the urticaria continues for 23 months, the patient should probably be referred to a dermatologist for further evaluation. In general, the focus of such investigations will be on internal disorders associated with urticaria (Table 8. Even after extensive evaluation and environmental change, the cause cannot always be found. Many patients with chronic urticaria are sure that their problems could be solved by intensive allergy tests, and ask repeatedly for them, but this is seldom worthwhile. Cetirizine 10 mg/day and loratadine 10 mg/day, both with half-lives of around 12 h, are useful. Type Cold urticaria Treatment Avoid cold Protective clothing Antihistamines Avoid sun exposure Protective clothing Sunscreens and sun blocks Beta-carotene Antihistamines Avoid heat Minimize anxiety Avoid excessive exercise Anticholinergics Antihistamines Tranquillizers Avoid trauma Antihistamines Avoid trauma Attenuated androgenic steroids as prophylaxis Tracheotomy may be necessary Remove cause Antihistamines (H1 + H2) Sympathomimetics Systemic steroids (rarely justified) Avoid aspirin-containing drugs Solar urticaria Cholinergic urticaria Dermographism Hereditary angioedema with shorter acting antihistamines. Alternatively they can be combined with a longer acting antihistamine (such as chlorpheniramine maleate 12 mg sustainedrelease tablets every 12 h) so that peaks and troughs are blunted, and histamine activity is blocked throughout the night. If the eruption is not controlled, the dose of hydroxyzine can often be increased and still tolerated. Chlorpheniramine or diphenhydramine are often used during pregnancy because of their long record of safety, but cetirizine, loratidine and mizolastine should be avoided. Sympathomimetic agents can help urticaria, although the effects of adrenaline (epinephrine) are short lived. A tapering course of systemic corticosteroids may be used, but only when the cause is known and there are no contraindications, and certainly not as a panacea to control chronic urticaria or urticaria of unknown cause. Viral infections, especially: herpes simplex hepatitis A, B and C mycoplasma orf Bacterial infections Fungal infections coccidioidomycosis Parasitic infestations Drugs Pregnancy Malignancy, or its treatment with radiotherapy Idiopathic but other factors have occasionally been implicated (Table 8. Presentation the symptoms of an upper respiratory tract infection may precede the eruption. Typically, annular nonscaling plaques appear on the palms, soles, forearms and legs. A new lesion may begin at the same site as the original one, so that the two concentric plaques look like a target. The StevensJohnson syndrome is a severe variant of erythema multiforme associated with fever and mucous membrane lesions. The oral mucosa, lips and bulbar conjunctivae are most commonly affected, but the nares, penis, vagina, pharynx, larynx and tracheobronchial tree may also be involved. Course Crops of new lesions appear for 1 or 2 weeks, or until the responsible drug or other factor has been eliminated. Individual lesions last several days, and this differentiates them from the more fleeting lesions of an annular urticaria. The site of resolved lesions is marked transiently by hyperpigmentation, particularly in pigmented individuals. A recurrent variant of erythema multiforme exists, characterized by repeated attacks; this merges with a rare form in which lesions continue to develop over a prolonged period, even for years. However, severe lesions in the tracheo-bronchial tree of patients with StevensJohnson syndrome can lead to asphyxia, and ulcers of the bulbar conjunctiva to blindness. Genital ulcers can cause urinary retention, and phimosis or vaginal stricture after they heal. Differential diagnosis Erythema multiforme can mimic the annular variant of urticaria as described above. Its acral distribution, the way individual lesions last for more than 24 h, their purple colour and the involvement of mucous membranes all help to identify erythema multiforme. Its main features are epidermal necrosis and dermal changes, consisting of endothelial swelling, a mixed lymphohistiocytic perivascular infiltrate and papillary dermal oedema. The abnormalities may be predominantly epidermal or dermal, or a combination of both; they probably depend on the age of the lesion biopsied. A search for other infectious agents, neoplasia, endocrine causes or collagen disease is sometimes necessary, especially when the course is prolonged or recurrent. However, the dose should be tapered rapidly or stopped because prolonged treatment in the Stevens Johnson syndrome has been linked, controversially, with a high complication rate. The prevention of secondary infection, maintenance of a patent airway, good nutrition, and proper fluid and electrolyte balance are important. Herpes simplex infections should be suspected in recurrent or continuous erythema multiforme of otherwise unknown cause. Treatment with oral acyclovir 200 mg three to five times daily or valciclovir 500 mg twice daily (Formulary 2, p. Erythema nodosum Erythema nodosum is an inflammation of the subcutaneous fat (a panniculitis). It is an immunological reaction, elicited by various bacterial, viral and fungal infections, malignant disorders, drugs and by a variety of other causes (Table 8. Treatment the best treatment for erythema multiforme is to identify and remove its cause. In mild cases, only symptomatic treatment is needed and this includes the use of antihistamines. The StevensJohnson syndrome, on the other hand, may demand immediate consultation between dermatologists and specialists in other fields such as ophthalmology, urology and infectious diseases, depending on the particular case. The use of Presentation the characteristic lesion is a tender red nodule developing alone or in groups on the legs and forearms or, rarely, on other areas such as the thighs, face, breasts or other areas where there is fat. Differential diagnosis the differential diagnosis of a single tender red nodule is extensive and includes trauma, infection (early cellulitis or abscess) and phlebitis. When lesions are multiple or bilateral, infection becomes less likely unless the lesions are developing in a sporotrichoid manner (p. Other causes of a nodular panniculitis, which may appear like erythema nodosum, include panniculitis from pancreatitis, cold, trauma, injection of drugs or other foreign substances, withdrawal from systemic steroids, lupus erythematosus, superficial migratory thrombophlebitis, polyarteritis nodosa and a deficiency of 1-antitrypsin. Some people use the term nodular vasculitis to describe a condition like erythema nodosum that lasts for more than 6 months. If the results are normal, and there are no symptoms or physical findings to suggest other causes, extensive investigations can be deferred because the disease will usually resolve. Like other reactive erythemas, erythema nodosum may persist if its cause is not removed. The ideal treatment for erythema nodosum is to identify and eliminate its cause if possible. For reasons that are not clear, potassium iodide in a dosage of 400900 mg/day can help, but should not be used for longer than 6 months. Leucocytoclastic (small vessel) vasculitis (Syn: allergic or hypersensitivity vasculitis, anaphylactoid purpura) Cause Immune complexes may lodge in the walls of blood vessels, activate complement and attract polymorphonuclear leucocytes. Antigens in these immune complexes include drugs, auto-antigens, and infectious agents such as bacteria. Presentation the most common presentation of vasculitis is painful palpable purpura. Crops of lesions arise in dependent areas (the forearms and legs in ambulatory patients, or on the buttocks and flanks in bedridden ones;. HenochSchцnlein purpura is a small vessel vasculitis associated with palpable purpura, arthritis and abdominal pain, often preceded by an upper respiratory tract infection. Urticarial vasculitis is a small vessel vasculitis characterized by urticaria-like lesions which last for longer than 24 h, leaving bruising and then pigmentation (haemosiderin) at the site of previous lesions. Course the course of the vasculitis varies with its cause, its extent, the size of blood vessel affected, and the involvement of other organs. Complications Vasculitis may simply be cutaneous; alternatively, it may be systemic and then other organs will be damaged, including the kidney, central nervous system, gastrointestinal tract and lungs. Differential diagnosis Small vessel vasculitis has to be separated from other causes of purpura (p. Occasionally, the vasculitis may look like urticaria if its purpuric element is not marked. Investigations Investigations should be directed toward identifying the cause and detecting internal involvement. Questioning may indicate infections; myalgias, abdominal pain, claudication, mental confusion and mononeuritis may indicate systemic involvement. However, the most important test is urine analysis, checking for proteinuria and haematuria, because vasculitis can affect the kidney subtly and so lead to renal insufficiency. Tests for hepatitis virus, cryoglobulins, rheumatoid factor and antinuclear antibodies may also be needed. Direct immunofluorescence can be used to identify immune complexes in blood vessel walls, but is seldom performed because of false-positive and false-negative results, as inflammation may destroy the complexes in a true vasculitis and induce non-specific deposition in other diseases. HenochSchцnlein vasculitis is confirmed if IgA deposits are found in the blood vessels of a patient with the clinical triad of palpable purpura, arthritis and abdominal pain. Patients whose vasculitis is damaging the kidneys or other internal organs may require systemic corticosteroids or immunosuppressive agents such as cyclophosphamide. Polyarteritis nodosa Cause this necrotizing vasculitis of large arteries causes skin nodules, infarctive ulcers and peripheral gangrene. Immune complexes may initiate this vasculitis, and sometimes contain hepatitis B or C virus or antigen. The skin over them may ulcerate or develop stellate patches of purpura and necrosis. Splinter haemorrhages and a peculiar net-like vascular pattern (livedo reticularis) aid the clinical diagnosis. The disorder may be of the skin only (cutaneous polyarteritis nodosa), or also affect the kidneys, heart muscle, nerves and joints. Patients may be febrile, lose weight and feel pain in the muscles, joints or abdomen. Investigations for cryoglobulins, rheumatoid factor, antinuclear antibody, antineutrophil antibodies and hepatitis C and B surface antigen are worthwhile, as are checks for disease in the kidneys, heart, liver and gut. The use of biopsy to confirm the diagnosis of large vessel vasculitis is not always easy as the arterial involvement may be segmental, and surgery itself difficult. Affected vessels show aneurysmal dilatation or necrosis, fibrinoid changes in their walls, and an intense neutrophilic infiltrate around and even in the vessel wall. Low-dose systemic steroids alone are usually sufficient for the purely cutaneous form. Antineutrophil antibodies are present in most cases and are a useful but non-specific diagnostic marker. Cyclophosphamide is the treatment of choice, used alone or with systemic steroids. Joint Task Force on Practice Parameters (2000) the diagnosis and management of urticaria: a practice parameter. Only half of the patients have skin lesions, usually symmetrical ulcers or papules on the extremities. Other 9 Bullous diseases Blisters are accumulations of fluid within or under the epidermis. They have many causes, and a correct clinical diagnosis must be based on a close study of the physical signs. Intraepidermal blisters appear within the prickle cell layer of the epidermis, and so have thin roofs and rupture easily to leave an oozing denuded surface: this tendency is even more marked with subcorneal blisters, which form just beneath the stratum corneum at the outermost edge of the viable epidermis, and therefore have even thinner roofs. Sometimes the morphology or distribution of a bullous eruption gives the diagnosis away, as in herpes simplex or zoster. Sometimes the history helps too, as in cold or thermal injury, or in an acute contact dermatitis. When the cause is not obvious, a biopsy should be taken to show the level in the skin at which the blister has arisen. A list of differential diagnoses, based on the level at which blisters form, is given in. The bulk of this chapter is taken up by the three most important immunobullous disordersapemphigus, pemphigoid and dermatitis herpetiformis (Table 9. Our understanding of both groups has advanced in parallel, as several of the skin components targeted by autoantibodies in the immunobullous disorders are the same as those inherited in an abnormal form in epidermolysis bullosa. Location of bullae Diseases Bullous impetigo Miliaria crystallina Staphylococcal scalded skin syndrome Subcorneal bulla Acute eczema Viral vesicles Pemphigus Miliaria rubra Incontinentia pigmenti Intra-epidermal bulla Sub-epidermal bulla Bullous pemphigoid Cicatricial pemphigoid Pemphigoid gestationis Dermatitis herpetiformis Linear IgA disease Bullous erythema multiforme Bullous lichen planus Bullous lupus erythematosus Porphyria cutanea tarda Toxic epidermal necrolysis Cold or thermal injury Epidermolysis bullosa. Bullous disorders of immunological origin In pemphigus and pemphigoid, the damage is done by autoantibodies directed at molecules that norm- ally bind the skin (p. This type of mechanism has not yet been proven for dermatitis herpetiformis; but the characteristic deposition of immunoglobulin (Ig) A in the papillary dermis, and an association with a variety of autoimmune disorders, both suggest an immunological basis for the disease.

The most common is pemphigus vulgaris, which accounts for at least three-quarters of all cases, and for most of the deaths. The other important type of pemphigus, superficial pemphigus, also has two variants: the generalized foliaceus type and localized erythematosus type. A few drugs, led by penicillamine, can trigger a pemphigus-like reaction, but autoantibodies are then seldom found. Finally, a rare type of pemphigus (paraneoplastic pemphigus) has been described in association with a thymoma or an underlying carcinoma; it is characterized by unusually severe mucosal lesions.

Although the 2005 guidelines list it as an alternative agent treatment of hyperkalemia order eldepryl 5mg with amex, efavirenz may have a higher rate of significant adverse effects than other listed agents medications j tube purchase 5 mg eldepryl with amex. Additionally treatment of scabies cheap 5mg eldepryl amex, efavirenz should not be used with pregnant women 25 medications to know for nclex buy eldepryl 5mg cheap, because of possible teratogenicity. The assessed risk also helps to determine whether a "basic" twodrug regimen or an "expanded" regimen consisting of three or more drugs should be selected. Follow-Up Exposed workers should be evaluated at 1 week for review of all test results. In addition to health education counseling, many exposed workers need emotional support during their follow-up visits. Addendum: Workplace Obligations · the health care institution has certain obligations to an exposed employee. In such situations, clinical supervisors or school or university officials often are the first contact for notification. Section 3: Health Maintenance and Disease Prevention · Puro V, Francisci D, Sighinolfi L, et al. In cases of sexual assault, evidence collection and specific paperwork may be required as well. In injection drug users, examine for abscesses and signs or symptoms of infection. An algorithm for risk evaluation and treatment decisions is presented in Figure 1. Nonoccupational Postexposure Prophylaxis delavirdine, nevirapine, and the combination of didanosine + stavudine. Although the 2005 guidelines designate it as a preferred agent, efavirenz may have a higher rate of significant adverse effects than other listed agents. Follow-Up Patients should be evaluated at 1 week for review of all test results and further risk reduction counseling. Patients need health education and riskreduction counseling and emotional support during their follow-up visits. To this end, many programs have case managers, social workers and health educators as the key providers of follow-up and counseling after an exposure, with referral to clinicians as needed. If patients have questions about access to condoms or clean needles, they should contact their care provider for assistance. Each patient visit presents an opportunity to provide effective prevention interventions, even in busy clinical settings. However, health care providers can help patients understand the transmission risk of certain types of behavior and help patients establish personal prevention strategies (sometimes based on a harm-reduction approach) for themselves and their partners. In these cases, referrals to mental health clinicians or other professional resources such as prevention case management may be helpful. If the patient can read well, printed material can be given to reinforce education in key areas, but it cannot replace a direct conversation with the clinician. Preparation: the patient is ready to Techniques for Brief, Effective Interventions by Providers A number of strategies have been shown to be more effective than providing information alone. Effective and brief provider-initiated interventions include the following elements: · Establish rapport and provide services in an understanding, nonjudgmental manner. Patient educators, nurses, peer counselors, social workers, and mental health providers may be effective in discussing prevention strategies with patients. See the key areas of risk assessment and Section 3: Health Maintenance and Disease Prevention change soon; discuss a concrete action plan and connect the patient with appropriate resources as needed. Maintenance: the patient has made behavioral changes; continue to discuss and address challenges, offer encouragement and congratulations. Such interventions may be carried out for 5-10 minutes per visit over a series of visits. Precontemplation: the patient is not Examples of Prevention Intervention Programs with Demonstrated Efficacy in Treatment Settings the U. Training and educational materials for ready to change; reassess at subsequent visits. The following three approaches have demonstrated efficacy in treatment settings: · Options/Opciones Program: the program features brief, 5-10 minute patient-centered discussions between patients and providers at each clinic visit using motivational interviewing techniques. The provider and the patient develop an individually tailored plan, which the provider writes out on a prescription pad and gives to the patient. The approach fea- 133 tures loss-framed messages that emphasize the risks or negative consequences of risky behavior. The messages are delivered with motivational interviewing principles, using a patientcentered, empathetic and nonjudgmental approach. After the video session, the computer prints out an individualized educational sheet for the patient and an assessment sheet for the provider to use for follow-up. Section 3: Health Maintenance and Disease Prevention Summary of Prevention with Positives: Key Areas of Intervention More detailed discussions of topics follow this table. Key Areas of Risk Assessment and Intervention Topic General Risk Assessment Questions, Assessment, and Plan Subjective/objective questions to ask: 1. What has made it more difficult for you to use condoms during this sexual encounter or with this partner? Other information to collect: · Number of sex partners in the past 6 months · Gender of each partner · Type of relationship with each partner (main, casual, anonymous) · Type of sexual activity engaged with each partner · Safer and less-safe sexual practices with each partner · Substance use, including alcohol, associated with sex · Circumstances of risky sex behaviors. Sexual Practices Section 3: Health Maintenance and Disease Prevention Partner Notification Subjective/objective questions to ask: 1. Assessment and plan: ways to offer help for disclosure · Local health departments may have programs that help conduct partner tracing and contact in a confidential manner. For example, screen every 3-6 months for a patient with new sex partners or new druginjecting partners. Section 3: Health Maintenance and Disease Prevention Drug and Alcohol Risk Assessment Subjective/objective questions to ask: 1. What are your thoughts about quitting or cutting down on drug and alcohol use, and about separating it from sex? Mental illnesses such as bipolar disorder, depression, and posttraumatic stress disorder can increase the chances of risky sexual and drug-use behaviors. Ask about mental health illnesses directly and pay attention to any symptoms that may indicate a psychiatric illness. Tell me about any previous diagnoses or hospitalizations for mental health illnesses. Needle-Use Practices Section 3: Health Maintenance and Disease Prevention Mental Health Assessment Pregnancy Screening Subjective/objective questions to ask: For women of childbearing potential: 1. Are you currently pregnant or wanting to become pregnant at some point in the future? This also will help prevent the transmission of other bloodborne or sexually transmitted infections, including hepatitis C, from coinfected patients. It is important to recognize that not every patient seeks the complete elimination of risk. The clinician may help the patient select and practice behaviors that are likely to be less risky. Certainly, if the patient is dealing with a dual or triple diagnosis (including substance abuse or mental illness), a referral to address those needs is indicated. The provider should prompt patients to consider several questions about disclosure, including how they might approach the discussion, how their partners might react, what information they might offer their partners, whether partners are likely to keep their status confidential, and whether they have any concerns about personal safety. If patients fear violence or retaliation or are not ready to share their status but want their partners to know, the provider may offer assistance with partner notification, for example through the local health department, in a confidential manner. As an alternative, patients may want the provider to talk with their partners, and that option can be offered as well. Make sure that the condom is undamaged, intercourse and can and that its expiration date has not damage the rectal Helping Patients passed. N-9 never · Carefully handle the condom to avoid Reduce the should be used for damage. In the event of allergy to latex or other difficulty with latex condoms, polyurethane male or female condoms may be substituted. Oil-based lubricants (such as mineral oil, cooking oil, massage oil, body lotion, and petroleum jelly) can weaken latex or cause it to break, although they are fine with the use of polyurethane condoms. For patients who complain about lack of sensitivity with condom use, the following techniques may help: · Apply a drop of lubricant inside the condom (not more, because it increases the risk that the condom will come off). It is a thin polyurethane pouch with a flexible ring at the opening, and another unattached flexible ring that sits inside the pouch to keep it in position in the vagina (for use in the anus, the inner ring must be removed and discarded). The female condom may be an option for women whose male partners will not use male condoms or for couples who do not like standard condoms. Female condoms are more expensive than male condoms, but may be procured at a lower cost at some health departments or Planned Parenthood clinics. Be sure the patient knows how to use the insertive condom before she or he needs it; after teaching, encourage practice when alone at home and unhurried. Women who have used the diaphragm, cervical cap, or contraceptive sponge may find it easy to use the female condom. Instructions for Use of Insertive (Female) Condoms Vaginal Intercourse · Open the pouch by tearing at notched edge of packet, and take out the female condom. Be sure that the lubricant is evenly distributed on the inside by rubbing the outsides together. While holding the outside of the pouch, squeeze the inner ring with your thumb and middle finger. Still squeezing, spread the labia with your other hand and insert the closed end of the pouch into the vagina. If, during intercourse, the outer ring is pushed inside the vagina, stop, remove the female condom, and start over with a new one. Extra lubricant on the penis or the inside of the female condom may help keep this from happening. Put the female condom on the penis of the insertive partner and insert the condom with the penis, being careful not to push the outer ring into the rectum. If alcohol or other drugs are posing barriers to practicing safer behaviors, the provider should counsel the patient to reduce or avoid substance use before engaging in sex, or refer the patient to prevention case management for more specialized risk reduction. Thus, most public health and prevention specialists focus their attention on riskier sexual and drug-use behaviors. Patients (and their partners) should avoid oral-genital contact if they have these conditions. Similarly, patients and partners can further reduce risk by not brushing or flossing teeth before oral sex. In addition, they (or their partners) may benefit from techniques such as insulating the end of the crack pipe to reduce burns while smoking. Assess whether referral for treatment is appropriate, and be knowledgeable about referral resources and mechanisms. Refer to an addiction counselor for motivational interviewing or other interventions, if available. After completion of substance abuse treatment, relapse prevention programs and ongoing support will be needed. Local harm-reduction activists may be aware of specific programs for obtaining clean needles and syringes. Although intervention to reduce the risk of perinatal infection is most effective if begun early in pregnancy, or preferably before pregnancy, it may be beneficial at any point in the pregnancy, even as late as during labor. These straws easily can penetrate fragile nasal mucosa and become contaminated with blood from one user before being used by another individual, who may then experience mucous membrane exposure or even a cut or break in the mucous membrane from the bloody object. Studies of various types of biomedical prevention in various populations are ongoing. Acupuncturists generally use sterile needles, but clients should verify that before using their services. Department of Health and Human Services, Health Resources and Services Administration. Vaccine Recommendations Vaccine Type Pneumococcal (polysaccharide) Section 3: Health Maintenance and Disease Prevention Recommendation · Recommended for all; consider revaccination 5 years after initial vaccination; some experts recommend vaccination every 5 years. All patients traveling to other countries should be evaluated for both routine and destination-specific immunizations and prophylaxes. The following should be noted about specific vaccinations: · Inactivated (killed), enhanced-potency polio and typhoid vaccines should be given instead of the live, attenuated forms. In adults aged >18, vaccinate 8 weeks before travel to allow time for the initial two doses of polio vaccine. Instead, immune globulin should be given to measles-susceptible, severely immunocompromised persons traveling to measles-endemic countries. If travel to a zone with yellow fever is necessary and vaccination is not administered, patients should be advised about the risk of yellow fever, instructed about avoiding the bites of vector mosquitoes, and provided with a vaccination waiver letter (though travelers should be warned that not all countries accept waiver letters). Immunocompromised patients should be protected on the basis of influenza risk at the destination. Among the ubiquitous pathogens are Candida, Mycobacterium avium complex, Pneumocystis jiroveci pneumonia, and human herpesvirus 6 and 7. Exposure to other opportunistic pathogens may be minimized if patients are aware of the risks. If this is not possible, treatment with iodine or chlorine, especially if in conjunction with filtering, reduces risk of infection. Recommended avoidance measures Preventing Exposure to Opportunistic and Other Infections Food Associated Pathogens · Toxoplasma · Salmonella, Shigella, Campylobacter (enteric infections) · Listeria · Cryptosporidium · Other enteric pathogens 149 Transmission Recommended avoidance measures · Exposure may occur through eating or handling contaminated food. Hard cheeses, processed cheeses, cream cheese, cottage cheese, and yogurt generally are safe. Section 3: Health Maintenance and Disease Prevention Environmental Pathogens · Toxoplasma gondii · Cryptosporidium · Coccidioides · Histoplasma capsulatum · Cryptococcus neoformans · Aspergillus Transmission · Cryptosporidium and Toxoplasma may be present in soil and sands, and infection can occur through handling soil during gardening or playing in or cleaning sandboxes. Those with highrisk partners or sexual practices should be screened more frequently.
Syndromes
Acute intermittent porphyria this condition medications similar buspar order eldepryl 5mg amex, inherited as an autosomal dominant trait as a result of mutations of the porphobilinogen deaminase gene medicine 2016 generic 5mg eldepryl with mastercard, is most common in Scandinavia medicine 0552 purchase 5mg eldepryl. Attacks of abdominal pain treatment laryngitis 5mg eldepryl with amex, accompanied by neuropsychiatric symptoms and the passage of dark urine symptoms precede an illness purchase 5mg eldepryl visa, are sometimes triggered by drugs (especially barbiturates 10 medications that cause memory loss generic eldepryl 5 mg, griseofulvin, oestrogens and sulphonamides). Variegate porphyria this disorder, inherited as an autosomal dominant trait, and a result of mutations of the protoporphyrinogen oxidase gene, is particularly common in South Africa. It is seen in a few patients on haemodialysis, and can be induced by some drugsanotably frusemide (furosemide) and non steroidal anti-inflammatory drugs. A diffuse thickening and papulation of the skin may occur in connection with an immunoglobulin G (IgG) monoclonal paraproteinaemia. Xanthomas Deposits of fatty material in the skin and subcutaneous tissues (xanthomas) may provide the first clue to important disorders of lipid metabolism. They fall into six groups, classified on the basis of an analysis of fasting blood lipids and electrophoresis of plasma lipoproteins. All, save type I, carry an increased risk of atherosclerosisain this lies their importance and the need for treatment. Secondary hyperlipidaemia may be found in a variety of diseases including diabetes, primary biliary cirrhosis, the nephrotic syndrome and hypothyroidism. Some metabolic disorders Amyloidosis Amyloid is a protein that can be derived from several sources, including immunoglobulin light chains and probably keratins. It is deposited in the tissues under a variety of circumstances and is then usually in combination with a P component derived from the plasma. Systemic amyloidosis of the type that is secondary to chronic inflammatory disease, such as rheumatoid arthritis or tuberculosis, tends not to affect the skin. In contrast, skin changes are prominent in primary systemic amyloidosis, and also in the amyloid associated with multiple myeloma. The waxy deposits of amyloid, often most obvious around the eyes, may also be purpuric. These are uncommon and usually take the form of macular areas of rippled pigmentation, or of plaques made up of coalescing papules. It is inherited as an autosomal recessive trait, the abnormal gene lying on chromosome region 12q22-q24, and is caused by a deficiency of the liver enzyme phenylalanine hydroxylase, which catalyses the hydroxylation Mucinoses the dermis becomes infiltrated with mucin in certain disorders. Pink or flesh-coloured mucinous plaques are seen on the lower shins, together with marked exophthalmos, in some patients with hyperthyroidism. This leads to the accumulation of phenylalanine, phenylpyruvic acid and their metabolites. The accumulation of phenylalanine and its metabolites damages the brain during the phase of rapid development just before and just after birth. Mental retardation, epilepsy and extrapyramidal manifestations such as athetosis and mental retardation may then occur. The Guthrie test, which detects raised blood phenylalanine levels, is carried out routinely at birth in most developed countries. A low-phenylalanine diet should be started as soon as possible to prevent further neurological damage. Alkaptonuria In this rare recessively inherited disorder, based on a homogentisic acid oxidase deficiency, dark urine may be seen in childhood, and in adult life pigment may be deposited in various places including the ears and sclera. The skin lesions are grouped, almost black, small telangiectatic papules especially around the umbilicus and pelvis. Some female carriers have skin changes, although these are usually less obvious than those of affected males. Similar skin lesions may be seen in lysosomal storage disorders such as fucosidosis. The itching here is usually triggered by a hot bath; it has a curious pricking quality and lasts about an hour. Paroxysmal pruritus has been recorded in multiple sclerosis and in neurofibromatosis. Brain tumours infiltrating the floor of the fourth ventricle may cause a fierce persistent itching of the nostrils. The search for a cause has to be tailored to the individual patient, and must start with a thorough history and physical examination. Unless a treatable cause is found, therapy is symptomatic and consists of sedative antihistamines, and the avoidance of rough clothing, overheating and vasodilatation, including that brought on by alcohol. Local Generalized pruritus Pruritus is a symptom with many causes, but not a disease in its own right. Itchy patients fall into two groups: those whose pruritus is caused simply by surface causes. Cholestyramine often helps cholestatic pruritus, possibly by promoting the elimination of bile salts. Urea itself seems not to be responsible for this symptom, which plagues about one-third of patients undergoing renal dialysis. This lady could not reach her upper back but could scratch her skin everywhere else. Pyoderma gangrenosum An inflamed nodule or pustule breaks down centrally to form an expanding ulcer with a polycyclic or serpiginous outline, and a characteristic undermined bluish edge. The condition is not bacterial in origin but its pathogenesis, presumably immunological, is not fully understood. It may arise in the absence of any underlying disease, but tends to associate with the following conditions. Otherwise the condition responds to systemic steroids but not to antibiotics, and lesions heal leaving papery scars. The skin changes of pregnancy Physiological A darkening of the nipples, genitals, and of a line down the centre of the abdominal wall, is often accompanied by a generalized increase in skin pigmentation. Spider naevi and palmar erythema are both common in pregnancy, and are caused by high oestrogen levels. Dermatoses of pregnancy Itching is common in pregnancy, usually for obvious reasons such as scabies, but sometimes in association with mild cholestasis. The terminology of the more striking itchy dermatoses of pregnancy has always been confusing. The urticated lesions favour the abdomen, particularly in association with stretch marks. However, the autoantibodies are directed at the same antigens as those of ordinary pemphigoid (p. The condition may start at any time during pregnancy, or even just after childbirth, tending to start earlier in subsequent pregnancies. Systemic corticosteroids are usually required, and there may be a risk of premature delivery. Effect of pregnancy on other dermatoses Candidiasis is common in pregnancy and genital warts can become unusually luxuriant. The effects of pregnancy on common disorders, such as atopic eczema, acne and psoriasis, are unpredictable in any individual patient, but there is an overall trend towards improvement. The relationships between the mind and the skin are usually subtler and more complex than this. Nevertheless, patients with skin disorders do have a higher prevalence of psychiatric abnormalities than the general population, although specific personality profiles and disorders can seldom be tied to specific skin diseases. Similarly, it is still not clear how, or even how often, psychological factors trigger, worsen or perpetuate such everyday problems as atopic eczema or psoriasis. Each school of psychiatry has its own theories on the subject, but their explanations do not satisfy everyone. Until more is known, it may be wise to adopt a simpler and more pragmatic approach, in which interactions between the skin and psyche are divided into two broad groups: · emotional reactions to the presence of skin disease, real or imagined; and · the effects of emotions on skin disease. Mental condition Skin disease causing psychological reactions Psychological factors affecting skin disease Skin condition. Reactions to skin disease the presence of disfiguring skin lesions can distort the emotional development of a child: some become withdrawn, others become aggressive, but many adjust well. At one end lies indifference to grossly disfiguring lesions and, at the other, lies an obsession with skin that is quite normal. Between these extremes are reactions ranging from natural anxiety over ugly skin lesions to disproportionate worry over minor blemishes. A chronic skin disease such as psoriasis can undoubtedly spoil the lives of those who suffer from it. It can interfere with work, and with social activities of all sorts including sexual relationships, causing sufferers to feel like outcasts. The heavy drinking of so many men with severe psoriasis is one result of these pressures. An experienced dermatologist will be on the lookout for depression and the risk of suicide, as up to 10% of patients with psoriasis have had suicidal thoughts. However, these reactions do not necessarily correlate with the extent and severity of the eruption as judged by an outside observer. Who has the more disabling problem: someone with 50% of his body surface covered in psoriasis, but who largely ignores this and has a happy family life and a productive job, or one with 5% involvement whose social life is ruined by it? Dermatological delusional disease Dysmorphophobia this is the term applied to distortions of the body image. Minor and inconspicuous lesions are magnified in the mind to grotesque proportions. The clinician can find no skin abnormality, but the distress felt by the patient leads to anxiety, depression or even suicide. They expect dermatological solutions for complaints such as hair loss, or burning, itching and redness of the face or genitals. The dermatologist, who can see nothing wrong, cannot solve matters and no treatment seems to help. Such patients are reluctant to see a psychiatrist although some may suffer from a monosymptomatic hypochondriacal psychosis. Other delusions these patients sustain single hypochondriacal delusions for long periods, in the absence of other recognizable psychiatric disease. In dermatology, many of these patients have the delusion that their skin is infested with parasites. Patients with delusions of parasitosis are unshakably convinced that they are already infested. No rational argument can convince them that they are not; the pest control agencies that they have called in, and their medical advisers therefore must both be wrong. These must be examined microscopically but usually turn out to be fragments of skin, hair, clothing, haemorrhagic crusts or unclassifiable debris. The skin changes may include gouge marks and scratches, but it is convenient to consider these patients separately from those with dermatitis artefacta. These patients become angry if doubts are cast on their ideas, or if they are referred to a psychiatrist. Family members may share their delusions and much tact is needed to secure any cooperation with treatment. Direct confrontations are best avoided; sometimes it may be best simply to treat with psychotropic drugs, explaining that these may be able to help some of the symptoms. The delusions of a few of these patients are based on an underlying depression or schizophrenia, and of a further few on organic problems such as vitamin deficiency or cerebrovascular disease. However, most patients suffer from monosymptomatic hypochondriacal delusions, which can often be suppressed by treatment with drugs, accepting that these will be needed long-term. Pimozide was once the most popular treatment for this condition but high doses carry cardiac risks. Risperidone, olanzapine and sulpiride are reasonable, and perhaps safer, alternatives. Others hint that their parasites still persist although this no longer disables them. Patients with dermatitis artefacta deny selftrauma but, naturally, if treatment is left to them to carry out, their problems do not improve. The lesions favour accessible areas, and do not fit with known pathological processes. The diagnosis is often difficult to make, but an experienced clinician will suspect it because there are no primary lesions and because of the bizarre shape or grouping of the lesions, which may be rectilinear or oddly grouped. Apart from frank malingerers, the patients are often young women with some medical knowledge, perhaps a nurse. The psychological problems may be superficial and easily resolved, but sometimes psychiatric help is needed and the artefacts are part of a prolonged psychiatric illness. Direct confrontation and accusations are usually best avoided, and the condition may last for some years. Neurotic excoriations Patients with neurotic excoriations differ from those with other types of dermatitis artefacta in that they admit to picking and digging at their skin. This habit affects women more often than men and is most active at times of stress. The clinical picture is mixed, with crusted excoriations and pale scars, often with a hyperpigmented border, lying mainly on the face, neck, shoulders and arms. Acne excoriйe Here the self-inflicted damage is based to some extent on the lesions of acne vulgaris, which may in themselves be mild, but become disfiguring when dug and squeezed to excess. A psychiatric approach is often unhelpful and a daily ritual of attacking the lesions, helped by a magnifying mirror, may persist for years. Localized neurodermatitis (lichen simplex) this term refers to areas of itchy lichenification, perpetuated by bouts of scratching in response to stress. In men, lesions are often on the calves; in women, they favour the nape of the neck where the redness and scaling look rather like psoriasis.
