Infection manifestations

Topical corticosteroids are used in cases of exacerbation and should be applied sparingly to the affected area. Hydrocortisone 1% twice a day or dexamethasone 0.1% applied to the periorbital area helps to relieve symptoms during these periods. Secondary infection manifested as blepharitis or keratoconjimctivitis should be treated with topical ophthalmic antibiotic ointments such as bacitracin or erythromycin.Topical antihistamines, NSAIDs, or mast cell stabilizers can be used to control itching, and topical steroids are sometimes required to treat severe keratoconjunctivitis associated with the atopic response. Because of side effects, steroids are not indicated for longterm use. 

In addition to bacterial and fungal infections, HSCT recipients also are at risk for serious HSV infections manifesting as severe gingivostomatitis, esophagitis, genital lesions, and rarely, pneumonia during the first month after transplant. Chnical disease is more common in patients with serologic evidence (e.g., serum antibodies)... 

Pegfilgrastim is a colony-stimulating factor (CSF) that stimulates neutrophil production within bone marrow. It decreases incidence of infection, manifested by febrile neutropenia, in patients with nomnyeloid malignancies receiving myelosuppressive anticancer drugs associated with febrile neutropenia. 

Other problems of product discoloration, pH drift, loss of viscosity, loss of performance can also result from products contaminated with microorganisms. No matter how the infection manifests itself, the consumer does not want to purchase a product that has the above issues.

Balantidiasis in humans is manifest by chronic episodes of intermittent diarrhea and constipation, symptoms similar to those of amebiasis. The patient may also have abdominal pain, tenderness over the colon, anorexia, nausea, severe weight loss, and weakness. The disease may be fatal and, before the avakabihty of a treatment, was the cause of death in approximately 30% of infected individuals. 

Leishmaniasis affects some 12 million humans aimuaHy ia an area where 350 million are at risk. It is a complex of at least two protozoan diseases, consisting primarily of cutaneous and visceral forms. A mucocutaneous form is considered by some to be another distinct variety. Clinical manifestations of the disease range from an asymptomatic infection to an infection ia which there is considerable destmction of cutaneous tissue and mucous membranes. Leishmaniasis can often be fatal, especially ia the visceral form. The seriousness of the disease depends on the state of the immunological system of the... 

Plasmodium vivax, responsible for the most prevalent form of malaria (benign tertian), has an incubation period of 8—27 days (14 average). A variety seen in northern and northeastern Europe has an incubation period as long as 8—10 months. The disease can cause splenic mpture and anemia. Relapses (renewed manifestations of erythrocytic infection) can occur with this type of malaria. Overall, P. vivax is stiU susceptible to chloroquine however, resistant strains have been reported from Papua New Guinea and parts of Indonesia. Plasmodium malariae the cause of quartan malaria, has an incubation period of 15—30 days and its asexual cycle is 72 hours. This mildest form of malaria can cause nephritis in addition to the usual symptoms. It is a nonrelapsing type of malaria but the ted blood ceU infection can last for many years. No resistance to chloroquine by this plasmodium has been reported. Plasmodium ovale responsible for ovale tertian malaria, has an incubation period of 9—17 days (15 average). Relapses can occur in people infected with this plasmodium. No chloroquine resistance has been reported for this parasite. 

AIDS (acquired immunodeficiency syndrome) is the final stage of disease caused by infection with HIV. In this stage, the vims infection has severely affected the immune system, causing a depletion of CD4+ T-helper cells. AIDS is characterized by the manifestation of typical diseases caused by opportunistic infections (Pneumocystis carinii pneumonia, CMV retinitis, candidiasis of the esophagus, cerebral toxoplasmosis), neurological manifestations, cachexia, or certain tumors (Kaposi sarcoma of the skin, B-cell lymphoma). 

Cytomegalovirus (CMV) is a herpesvirus, which causes an inapparent infection in immunocompetent persons. Worldwide, approximately 40% of people are infected with CMV. In immunocompromised patients, transplant recipients and neonates, CMV can cause serious and potentially lethal disease manifestations like pneumonia, retinitis and blindness, hepatitis, infections of the digestive tract, deafness or mental retardation. 

Urinary tract infection (UTI) is an infection caused by pathogenic microorganisms of one or more structures of the urinary tract. The most common structure affected is the bladder, with the urethra, prostate, and kidney also affected (see Pig. 47-1). Display 47-1 identifies the disorder most frequently associated with each of these structures within the urinary system. Clinical manifestations of a UTI of the bladder (cystitis) include urgency, frequency, burning and pain on urination, and pain caused by spasm in the region of the bladder and the suprapubic area. 

MANAGING HONE MARROW SUPPRESSION. Bone marrow suppression is a potentially dangerous adverse reaction resulting in decreased production of blood cells. Bone marrow suppression is manifested by abnormal laboratory test results and clinical evidence of leukopenia, thrombocytopenia, or anemia For example, there is a decrease in the white blood cells or leukocytes (leukopenia), a decrease in the thrombocytes (thrombocytopenia), and a decrease in the red blood cells, resulting in anemia Fhtients with leukopenia have a decreased resistance to infection, and the nurse must monitor them closely for any signs of infection. 

In severe cases, or those refractory to treatment, truncal and limb weakness may be accompanied by involvement of masticatory, bulbar, and respiratory muscles. However the most life-threatening clinical manifestations are those affecting the gastrointestinal tract, since stomach ulceration can occur and death from perforation and peritonitis are not unknown. Medication with steroidal antiinflammatory agents is necessary but weakens the childrens resistance to infection, so that systemic spread of usually self-limiting disorders, such as candidiasis, may occasionally occur.
