Management of Inflammatory Bowel Disease - Article
ABSTRACT: Patients with an inflammatory bowel disease, such as ulcerative colitis or Crohn's disease, have recurrent symptoms with considerable morbidity. Patient involvement and education are necessary components of effective management. Mild disease requires only symptomatic relief and dietary manipulation. Mild to moderate disease can be managed with 5-aminosalicylic acid compounds, including olsalazine and mesalamine. Mesalamine enemas and suppositories are useful in treating proctosigmoiditis. Antibiotics such as metronidazole may be required in patients with Crohn's disease. Corticosteroids are beneficial in patients with more severe symptoms, but side effects limit their use, particularly for chronic therapy. Immunosuppressant therapy may be considered in patients with refractory disease that is not amenable to surgery. Inflammatory bowel disease in pregnant women can be managed with 5-aminosalicylic acid compounds and corticosteroids. Since longstanding inflammatory bowel disease (especially ulcerative colitis) is associated with an increased risk of colon cancer, periodic colonoscopy is warranted.
American Thoracic Society Issues Consensus Statement on Sarcoidosis - Practice Guidelines
ABSTRACT: Acute respiratory distress syndrome manifests as rapidly progressive dyspnea, tachypnea, and hypoxemia. Diagnostic criteria include acute onset, profound hypoxemia, bilateral pulmonary infiltrates, and the absence of left atrial hypertension. Acute respiratory distress syndrome is believed to occur when a pulmonary or extrapulmonary insult causes the release of inflammatory mediators, promoting neutrophil accumulation in the microcirculation of the lung. Neutrophils damage the vascular endothelium and alveolar epithelium, leading to pulmonary edema, hyaline membrane formation, decreased lung compliance, and difficult air exchange. Most cases of acute respiratory distress syndrome are associated with pneumonia or sepsis. It is estimated that 7.1 percent of all patients admitted to an intensive care unit and 16.1 percent of all patients on mechanical ventilation develop acute lung injury or acute respiratory distress syndrome. In-hospital mortality related to these conditions is between 34 and 55 percent, and most deaths are due to multiorgan failure. Acute respiratory distress syndrome often has to be differentiated from congestive heart failure, which usually has signs of fluid overload, and from pneumonia. Treatment of acute respiratory distress syndrome is supportive and includes mechanical ventilation, prophylaxis for stress ulcers and venous thromboembolism, nutritional support, and treatment of the underlying injury. Low tidal volume, high positive end-expiratory pressure, and conservative fluid therapy may improve outcomes. A spontaneous breathing trial is indicated as the patient improves and the underlying illness resolves. Patients who survive acute respiratory distress syndrome are at risk of diminished functional capacity, mental illness, and decreased quality of life; ongoing care by a primary care physician is beneficial for these patients.
Atopic Dermatitis: An Overview - Article
ABSTRACT: Atopic dermatitis, also known as atopic eczema, is a chronic pruritic skin condition affecting approximately 17.8 million persons in the United States. It can lead to significant morbidity. A simplified version of the U.K. Working Party’s Diagnostic Criteria can help make the diagnosis. Asking about the presence and frequency of symptoms can allow physicians to grade the severity of the disease and response to treatment. Management consists of relieving symptoms and lengthening time between flare-ups. Regular, liberal use of emollients is recommended. The primary pharmacologic treatment is topical corticosteroids. Twice-daily or more frequent application has not been shown to be more effective than once-daily application. A maintenance regimen of topical corticosteroids may reduce relapse rates in patients who have recurrent moderate to severe atopic dermatitis. Pimecrolimus and tacrolimus are calcineurin inhibitors that are recommended as second-line treatment for persons with moderate to severe atopic dermatitis and who are at risk of atrophy from topical corticosteroids. Although the U.S. Food and Drug Administration has issued a boxed warning about a possible link between these medications and skin malignancies and lymphoma, studies have not demonstrated a clear link. Topical and oral antibiotics may be used to treat secondary bacterial infections, but are not effective in preventing atopic dermatitis flare-ups. The effectiveness of alternative therapies, such as Chinese herbal preparations, homeopathy, hypnotherapy/biofeedback, and massage therapy, has not been established.
Psoriasis - Article
ABSTRACT: Psoriasis is a chronic inflammatory skin condition that is often associated with systemic manifestations. It affects about 2 percent of U.S. adults, and can significantly impact quality of life. The etiology includes genetic and environmental factors. Diagnosis is based on the typical erythematous, scaly skin lesions, often with additional manifestations in the nails and joints. Plaque psoriasis is the most common form. Atypical forms include guttate, pustular, erythrodermic, and inverse psoriasis. Psoriasis is associated with several comorbidities, including cardiovascular disease, lymphoma, and depression. Topical therapies such as corticosteroids, vitamin D analogs, and tazarotene are useful for treating mild to moderate psoriasis. More severe psoriasis may be treated with phototherapy, or may require systemic therapy. Biologic therapies, including tumor necrosis factor inhibitors, can be effective for severe psoriasis and psoriatic arthritis, but have significant adverse effect profiles and require regular monitoring. Management of psoriasis must be individualized and may involve combinations of different medications and phototherapy.
ABSTRACT: The common cold, or upper respiratory tract infection, is one of the leading reasons for physician visits. Generally caused by viruses, the common cold is treated symptomatically. Antibiotics are not effective in children or adults. In children, there is a potential for harm and no benefits with over-the-counter cough and cold medications; therefore, they should not be used in children younger than four years. Other commonly used medications, such as inhaled corticosteroids, oral prednisolone, and Echinacea, also are ineffective in children. Products that improve symptoms in children include vapor rub, zinc sulfate, Pelargonium sidoides (geranium) extract, and buckwheat honey. Prophylactic probiotics, zinc sulfate, nasal saline irrigation, and the herbal preparation Chizukit reduce the incidence of colds in children. For adults, antihistamines, intranasal corticosteroids, codeine, nasal saline irrigation, Echinacea angustifolia preparations, and steam inhalation are ineffective at relieving cold symptoms. Pseudoephedrine, phenylephrine, inhaled ipratropium, and zinc (acetate or gluconate) modestly reduce the severity and duration of symptoms for adults. Nonsteroidal anti-inflammatory drugs and some herbal preparations, including Echinacea purpurea, improve symptoms in adults. Prophylactic use of garlic may decrease the frequency of colds in adults, but has no effect on duration of symptoms. Hand hygiene reduces the spread of viruses that cause cold illnesses. Prophylactic vitamin C modestly reduces cold symptom duration in adults and children.
