Explore ways in which patients have some power in the situation to control or modify risk. Abstinence from intercourse is likely to be most useful with adolescents, who may be encouraged to delay intercourse, and in situations where families or partners are separated by work or travel. If only one partner is faithful, the activities of the unfaithful partner may put the faithful one at risk. Although adequate information is a necessary condition to prevent transmission, it is often not a sufficient condition. In other words, there needs to be basic information, but by itself information will not always overcome barriers to actually doing preventive activities. These barriers may be situational (low power in a situation; the influence of alcohol or other drugs; potential violence; no condoms; or a need for food, shelter, or money). They may also be emotional (when people are highly attracted to their partner, when they want children, when they are sexually aroused); often, despite what people know, their emotions override their intentions. It is useful to have people describe the situations in which emotions may override their knowledge and judgment and to identify the point of no return beyond which unsafe sex is likely to occur. Here you can ask patients to describe how they would feel after putting themselves or others at risk and how significant others in their family or community might feel about their actions. The health care worker also has a special obligation to help the sick live and die with respect and dignity. Regardless of whether the health care worker personally has a spiritual or religious belief, the patient has an absolute right to be cared for and respected. One can do so by recognizing that the spiritual and religious needs of patients may be as important for their mental health and comfort as more widely recognized psychological and social supports. Cultures will differ on these myths and beliefs, but health workers must be able to list the most prevalent myths. Cognitive and emotional symptoms may include emotional numbness or hypersensitivity, overidentification with patients, grief and sadness, pessimism and hopelessness, cynicism, indecision and inattention, and depression. Providers suffer stigma similar to that of their patients and are often unable to talk with family and friends about their work with patients suffering from an often unmentionable disease. Half of the counselors said that they did not want to be tested because they did not want to deal with the hopelessness of a positive result or they thought it pointless because there is no cure and only limited treatment. These factors would seem to have a detrimental effect on the ability to counsel effectively or encourage others to seek testing. Often, there are insufficient resources, such as medication and supplies, to meet the needs of such patients. A high caseload combined with inadequate staffing makes it difficult to provide sufficient counseling to the patient. Like their patients, they display many of the symptoms of the stages of grief (denial, anger, guilt, bargaining, depression, and acceptance). Loss of multiple patients can lead to complicated and ongoing grief and can prevent the health care worker from processing the thoughts, feelings, and responses to patients in healthful and helpful ways. Over time, the unacknowledged sadness, anger, and guilt can become compressed and result in cynicism and decreased ability to invest emotionally in patients. It is painful to acknowledge the feelings associated with seeing patients suffer and die, so the professional becomes more hardened and expresses less sensitivity and sympathy for the needs of the next patient. Health care providers can help one another by creating a supportive environment in which they feel free to express their feelings. Formal support groups for health care providers can not only reduce feelings of isolation but also lead to new ways to cope with the stress of work. In these settings, it is often more important to discuss how the person feels about and responds to difficult situations, and to develop new ways to think about and respond to them, than to discuss in detail the situation itself. Informal discussions are also helpful because they can occur directly after a stressful experience. The goal should be for the person to express feelings, to see things in a new light, and to develop new skills and strategies for coping. The health care provider will need to evaluate the effects of stress on his or her life on an ongoing basis. Adequate rest, exercise, and nutrition are important for the promotion of health for the caregiver as well as the patient. Relaxation techniques such as progressive relaxation and breathing exercises can help the stressed professional to detach from stressful situations to address them more effectively. It is apparent that health workers, as members of local communities, may have some of the same community negative attitudes and beliefs until appropriate education and role modeling by senior colleagues and peers occurs.

If the signs of dehydration remain unchanged or worsen, and especially if the patient continues to pass watery stools, the rate of fluid administration and the total amount of fluid given for rehydration should be increased. Infants younger than 6 months who are not breast-fed should be given 100-200 mL of plain water during the first 6 h if they can drink. Older children and adults should be given water to drink as soon as they desire it, provided that vomiting has subsided. If signs of severe dehydration are still present, rehydration therapy must be continued per Treatment Plan C. Otherwise, further treatment should follow Plan B if some signs of dehydration remain or Plan A if there are no signs of dehydration. If possible, patients presenting with severe dehydration should be hospitalized until the diarrhea subsides. Infection with Shigella is the most common cause of dysentery, but other potential causes include infections with Salmonella, enterohemorrhagic and enteroinvasive E. The diagnosis of dysentery can be made by history of blood in the stool or by visual inspection of stool for blood. A stool sample should be sent to a lab, if available, for microscopy for fecal leukocytes and ova and parasites, and for culture and sensitivities, though in many settings doing so may not possible. Populations at risk for severe disease and poor outcomes related to dysentery include the following: infants younger than 1 year, especially those not breastfeeding; malnourished children; children recovering from measles infection in the last 6 weeks; and those who develop severe dehydration, altered consciousness, or have an associated convulsion. Malnourished children with dysentery should be admitted to a hospital for inpatient care, and strong consideration should be given to admitting these other high-risk populations. In the absence of these risk factors, most children can be treated as outpatients. Antibiotic treatment is recommended for children with dysentery, though resistance to routinely given antibiotics is a growing problem. The following antibiotics are ineffective against Shigella, and none of these should be given for the treatment of dysentery: metronidazole, tetracyclines, chloramphenicol, amoxicillin, aminoglycosides (gentamicin, kanamycin), nitrofurans (nitrofurantoin, furazolidone), and first- or second-generation cephalosporins. Cotrimoxazole and ampicillin were effective for Shigella, but there is now widespread resistance and these antibiotics should not be used empirically. Nalidixic acid is an antibiotic that was commonly used to treat dysentery but is currently not recommended for this indication. Treatment of dysentery should be guided by the local sensitivity pattern of Shigella isolates. The use of fluoroquinolones such as ciprofloxacin in children has been restricted because of the concern for joint damage that was seen as a side effect of these medications in animals. Sometimes, though, the benefits outweigh the small risks, and a short course of ciprofloxacin is both safe and effective for use in the treatment of dysentery in children. Other antibiotic options include extended215 Dysentery Dysentery is diarrhea with visible blood in the stool. Supportive care, including management of dehydration, appropriate feeding, provision of zinc, and control of fever and pain, should be given to all children just as in acute diarrhea according to the protocols referred to in the previous section. Malnourished children with dysentery should be admitted to a hospital for inpatient care. An antibiotic to which Shigella is sensitive should be given and its effect reassessed in 2 days. If the child is improved, as manifested by resolution of fever, fewer stools, less blood in the stools, and improved appetite and activity, the child should complete a 3- to 5-day course of the antibiotic. If the child is not improved after 2 days, the child should be given a second antibiotic to which Shigella is sensitive and reassessed 2 days later. If the child is improved at this point, a 5-day course of this antibiotic should be completed. If the child is still not improved, both admission to a hospital and a course of treatment for amoebiasis should be considered.

Children involved in the pandemic face a set of psychological and social issues that must be addressed, not overlooked. Death and bereavement are important aspects of chronic illness that must be addressed with children and their families. Adolescents are a unique population with a pivotal role in the future of the pandemic. This transition requires psychological adjustments, especially in the pediatric and adolescent populations. A chronic illness is a disorder with a protracted course that can be progressive and fatal or associated with a relatively normal life span despite impaired mental and/or physical functioning. To prevent resistance, the child must take the medications with a greater than 95% rate of adherence. This task can be difficult for an adult patient and increasingly difficult when the patient is a child or adolescent. As the patient gets older, he wants to have a sense of autonomy from his caregivers. Health care providers must guide the caregiver to ask the patient how to best be helpful regarding medication adherence. By giving the patient the power to direct the help from their caregivers, the patient feels a sense of control over the helping while the family can remain involved in the care. The stressors of a chronic illness can be more challenging when the patient is a child. This situation increases the necessity for caregivers and other family members to assist with medical care and activities of daily living. These challenges fall into three general areas: emotional, cognitive, and behavioral. Doing so includes grieving the loss of the idea of their once-healthy child, as well as guilt, sadness, and anger. They must understand the available treatment options and the importance of adherence to the prescribed medication regimen. The family should also be educated regarding the symptoms of disease progression and possible side effects of medications. This way the family will know what to look for when the child falls ill or develops new symptoms. The pediatric patient must have a developmentally appropriate understanding of why they see the doctor and why they take medications. Often, education with children is more successful with visual tools such as drawing and videos. Despite living with a chronic condition, children still need rules, discipline, and routines. Routines are especially important for children dealing with stressful or new situations because they help provide a sense of security. Living with a chronic illness can lead to psychological stress that can build over a long time. Also, living with a long-term chronic condition also lends a patient to experience burnout. He or she is frustrated with the medication regimen and the constant requirement to maintain greater than 95% adherence. Often families will shame or guilt their children into taking their medications consistently, which will wear down the patient mentally over time. Health care providers can help reduce patient burnout in chronic illness by using "the 4 Rs": 1. It is important to understand the long-term effects that these challenges can have on the children and their caregivers. Stigma can adversely affect children and their caregivers in ways that have long-term negative psychological and social effects. Previous work has defined stigma as "a negative, moral, or judgmental definition of a person or social situation, often connected to discredit, disgrace, blame, and ascription of responsibility for the conditions. It has been an evolving aspect of the disease since the first cases emerged in the early 1980s, and it has become prevalent in all geographic locations-even those with limited mass media influence.

Despite this, he suffered considerable corneal scarring with loss of visual acuity in the left eye. Following a major epileptic fit 8 days previously, she had been put on carbamazepine. On admission, she was pyrexial with extensive haemorrhagic ulceration of the mouth, which became too sore even to take fluids. A clinical diagnosis of Stevens­Johnson syndrome was made and she was treated immediately with systemic corticosteroids (45 mg daily). She improved symptomatically, but when an ophthalmologist was asked to see her 3 weeks later she was found to have severe conjunctival ulceration and punctate keratitis. Unfortunately, she then developed cicatricial entropion (inward-turning eyelids), with resulting corneal trauma. The lid deformity was surgically corrected and further corneal ulceration prevented by an extended-wear contact lens. These episodes occurred only when he was involved in small-animal work, particularly when handling rabbits. Each episode lasted for several hours and several recent episodes had been associated with sneezing and running of the nose, but no wheeze. He had also noticed that large, itchy weals developed on his skin if he was scratched by a rabbit. Skin-prick testing showed a marked positive response to rabbit proteins and moderate levels of rabbit-specific IgE were found in his blood. A diagnosis of allergic conjunctivitis and rhinitis due to rabbit hypersensitivity was made. He was able to limit the problem by taking a non-sedative antihistamine on the days when he was likely to be exposed to rabbits. The trigger, in genetically susceptible individuals, is usually a drug, often one given to treat infection (Table 12. Treatment of the ocular complications may be disappointing, although intensive, short-term, topical steroids help to reduce inflammation and prevent conjunctival ulceration, and alternative topical antibiotics are used to prevent super infection. This eye condition is characterized by erythematous, indurated lesions on the eyelids. Ophthalmic contact sensitizers include almost all topical drugs (such as antibiotic drops or atropine-like compounds), cosmetics and especially contact lens solutions. Seventy-five per cent of patients with arthritis urethritica (see Chapter 10) develop conjunctivitis. Uveitis (30%) is commoner than conjunctivitis (5%) in patients with sarcoidosis (see Chapter 13). Epithelial cells may be damaged during the primary infection, so that T lymphocytes become sensitized to persistent viral antigens or virally altered corneal antigens. Marginal ulcers are sometimes seen in response to staphylococcal infection, particularly in younger patients, and are thought to be due to deposited antigen­antibody complexes. An important complication is the peripheral corneal melting syndrome, which can lead to corneal perforation with prolapse of the uveal tissue ­ an ocular emergency. Keratoconjunctivitis sicca is inflammation resulting from insufficient lacrimal gland secretions. Treatment of dry eyes is difficult, as dryness is experienced only when the lacrimal glands are severely damaged. Although it is antigenic, the cornea is a poor inducer of allogeneic immune responses (see section 12. He also gave a 3-month history of relapsing and remitting ulceration of his mouth and scrotum. Ophthalmological examination showed a florid anterior uveitis of such severity that neutrophils in the anterior chamber settled out to form a fluid level visible to the naked eye: a hypopon. He was treated with oral and topical (ocular and mucosal) corticosteroids and a low dose of colchicine. However, 3 months later he developed painless deterioration of vision in the left eye and was found to have a severe retinal vasculitis.

An excisional biopsy is done and shows the following: · · · Inflammation in the panniculus and nonspecific inflammation in the dermis Hyalinized and sclerotic changes in several septae of the fat Areas of "pseudocyst" formation in the panniculus the changes above are characteristic for liposclerotic panniculitis and would fit the clinical picture. Most often seen involving the lower extremitiy in persons with a history of venous insufficiency and often obesity, this condition can be esasily mistaken for cellulitis and is sometimes referred to as "pseudocellulitis". The changes microscopically are not entirely specific but the changes seen in this slide are qite characteristic for this disorder. Clinical correlation is required as this pattern can also be seen in morphea profunda or connective tissue diseases as well. Histology typically shows 3 zones of inflammation: necrotic tissue, fibrin, neutrophils on the surface, granulation tissue in the middle, lymphocytes and plasma cells deep B. Typical histologic features include epidermal thinning or ulceration centrally, spongiosis and lichenoid interface dermatitis with exocytosis of lymphocytes, plasma cells and neutrophils. Typically presents with unimpressive 2-3mm papules on genitalia which are usually not biopsied; severe inguinal lymphadenopathy. Histology shows normal or ulcerated epidermis with diffuse dermal mixed infiltrate composed of lymphocytes, histiocytes, and plasma cells and non-specific granulation tissue. Ulcer with dense dermal infiltrate of histiocytes and plasma cells; as well as small neutrophil microabscesses. Parasitized macrophages may be large and have a typical vacuolated appearance (Donovan bodies). Question 48 Which of the following stains will most likely confirm the above diagnosis? Giemsa stain can be used to detect haemophilus ducreyi (chancroid) or calymmatobacterium granulomatis (granuloma inguinale) from a tissue smear, but not treponema pallidum. In primary syphilis, organisms can successfully be dectected in tissue sections from the chancre with IgG spirochete antibody immunohistochemistry. Fite stain is used to detect mycobacteria leprae (leprosy) but not spirochetes in syphilitic chancres. Calymmatobacterium granulomatis (granuloma inguinale) can be recognized, though often with some difficulty, on H&E sections, but spirochetes are not typically visualized on H&E sections. Clinical Features Syphilis is a sexually transmitted disease caused by the spirochete, Treponema pallidum. The primary stage of syphilis is marked by the appearance of a syphilitic chancre, which typically presents as a firm, round, painless papule, nodule, or plaque on the genitalia that progresses to a punched out ulceration. The time period between infection and onset of a chancre is approximately 3 weeks, but can range from 10 to 90 days. Once it appears, a chancre lasts approximately 3-6 weeks and heals regardless of whether a person is treated or not. With a tissue biopsy of a chancre, syphilis can be diagnosed with an immunohistochemical stain for treponema, which confirms their presence in the tissue. Treatment of primary syphilis with a single intramuscular injection of long acting Benzathine penicillin G (2. Histopathologic Features · Epidermal acanthosis peripherally with epidermal thinning or ulceration centrally · Spongiosis and exocytosis of lymphocytes, plasma cells and neutrophils · Lichenoid interface dermatitis occasionally · Papillary dermal edema and a dense perivascular and interstitial lymphohistiocytic and plasma-cellular infiltrate with endothelial cell swelling · Immunohistochemical staining shows abundant spirochetes References 1. The specimen was obtained from a painful 1cm shin red macule that arose 1 month after attempted transplantation. Sections of these organisms show narrow septate hyphae with acute angle branching, indistinguishable from Aspergillus spp. The fungi that reside in the soil and grow on degraded plant material are referred to as the dematiaceous fungi. The non-pigmented hyalohyphomycoses and pigmented phaeohyphomycoses can be distinguished on H&E stained sections. Disseminated dematiaceous fungal infection is rare, however most all reported cases occur in immunocompromised hosts. In one study, the most common isolate was Scedosporium prolificans, accounting for over a third of cases. The differential diagnosis of intravascular or vasculotropic fungi includes the Zygomycetes which are not self-pigmented. Therefore if zygomycetous infection is suspected alert the microbiology laboratory and request specific minced tissue processing which shows improved recovery and culture identification (Walsh 2012).
