Asthma

Q:What constitutes the optimal management of asthma ina pregnant patient?

For 2 months, a 35-year-old woman has been troubled by a bilateral pruritic eruption on her neck. The condition did not respond to a 3-week course of oral terbinafine. The patient has a history of childhood asthma; her only current medication is an oral contraceptive. She has had a cat for the past 2 years. She has not used any new shampoos or conditioners.

A 52-year-old woman was admitted tothe hospital with progressive shortnessof breath of 2 days’ duration. Bronchialasthma had been diagnosed 6 monthsearlier; inhaled corticosteroids, bronchodilators,and leukotriene antagonistswere prescribed. Despite aggressivetreatment, the patient’s dyspneaand wheezing worsened.

Although inhaled corticosteroids play a major role in the management of asthma, their effects on bone mineral density (BMD) are a concern for some patients. Fuhlbrigge and associates evaluated the cost-effectiveness of such therapy in light of the potential adverse effects on BMD. They found that inhaled corticosteroid therapy compares favorably with other standard medical interventions. However, the use of high doses over an extended period can affect overall costs and health.

A 28-year-old man presented with chest pain, hemoptysis, and wheezing. He had a history of intermittent shortness of breath that occurred at least 3 times a year in the past 3 years; fever; and loss of appetite associated with headache, vomiting, and weakness. His medical history also included asthma, chronic gastritis, and more than 5 episodes of pneumonia since 1996. A test for hepatitis C virus (HCV) had yielded positive results.

The association between asthma and pneumococcal disease has been suspected by many clinicians; however, formal investigations confirming an increased risk of pneumococcal disease in patients with asthma are rare. Often, studies examining risk factors for pneumococcal disease have grouped all chronic pulmonary diseases together with no delineation of the specific type of underlying disease.

A 35-year-old woman has been losing weight and has hadworsening abdominal pain and fullness for the past 2 months.She denies nausea, vomiting, and fever. Medical history issignificant only for asthma.

Q:What is the best and most efficient method ofevaluating pulmonary function in primary careoffice practice?

Abstract: In the assessment of central airway obstruction and disease, no imaging technique is an adequate substitute for bronchoscopy. The indications for rigid bronchoscopy include multiple malignant and benign disorders, with most interventions performed for treatment of complications of lung cancer. The rigid bronchoscope is a useful tool for managing most types of airway stenoses, and it facilitates other endobronchial therapies, including stent placement, argon plasma coagulation, balloon dilatation, electrocautery probes, and laser therapy. Certain patients with benign lesions or postintubation or post-tracheostomy stenosis may benefit from rigid bronchoscopic techniques instead of surgery. Although use of the rigid bronchoscope requires general anesthesia, it provides a stable airway and often results in fast removal of foreign bodies. (J Respir Dis. 2006;27(3):100-113)

Abstract: Smoking cessation is still the most important intervention in patients with chronic obstructive pulmonary disease (COPD), regardless of sex. There is some evidence that nicotine replacement therapy may be less effective in women than in men. However, women may derive greater benefits from a sustained quit attempt. For example, one study found that compared with men, women who were sustained quitters had a greater initial rise and a slower age-related decline in forced expiratory volume in 1 second. Men and women do not appear to differ in their response to bupropion or to the various types of bronchodilators. A number of factors contribute to the increased risk of osteoporosis in women with COPD. Both smoking and the degree of airflow obstruction have been identified as important risk factors for osteoporosis. Women may be particularly susceptible to the effects of smoking on bone metabolism. Immobility and decreased physical activity have also been shown to accelerate bone loss. (J Respir Dis. 2006;27(3):115-122)

Abstract: Inhalation of Aspergillus is responsible for a variety of lung infections and diseases; Aspergillus fumigatus is the most common causative agent. Allergic bronchopulmonary aspergillosis (ABPA), caused by sensitivity to A fumigatus, is diagnosed primarily in persons with asthma or cystic fibrosis. Differentiating ABPA from other Aspergillus-related lung infections and diseases is often challenging. A patient's symptoms, underlying risk factors, and any prior pulmonary disease contribute to the diagnosis. Findings include pulmonary infiltrates, total serum IgE levels greater than 1000 IU/mL, IgE and IgA anti-A fumigatus antibodies, peripheral blood and pulmonary eosinophilia, and central bronchiectasis. Untreated ABPA often results in chronic bronchiectasis, pulmonary fibrosis, and dependence on corticosteroids; an accurate diagnosis of ABPA is critical to avoiding irreparable disease.

New recommendations for the treatment of coughs caused by colds and for the vaccination of adults against pertussis are among the changes in the revised guidelines on the mangement of coughs.

A 56-year-old man presents with diffuse erythema. He has not changed his routine or eaten anything unusual. The rash initially appeared the previous night as asymptomatic erythema on the face and body. On awakening in the morning, the patient noticed that the erythema had spread over most of his body and had become pruritic. Over-the-counter diphenhydramine did not relieve the symptoms.

Some epidemiologic studies haveindicated that increased consumptionof margarine is a risk factor foratopy in children. Now, Nagel andLinseisen report that a high intakeof margarine is associated with anincreased risk of the developmentof adult-onset asthma.

A number of studies have found an increased prevalence of anxiety and depression in patients with asthma and chronic obstructive pulmonary disease (COPD). Although the relationship is not completely understood, it is clear that psychological disorders can adversely affect the course of both diseases.

A 36-year-old man who had collapsedand sustained a bruised right shoulderwas brought to the emergency departmentwith acute emesis, cephalgia,blurred vision, aphasia, and righthemiparesis. He was confused but ableto follow simple commands.

LPR is the movement of gastric contents beyond the esophagus up to the laryngeal and pharyngeal area. In addition to pepsin and acid, gastric contents may contain bile acids and pancreatic enzymes; reflux can injure tissues not adapted to the presence of these noxious materials.

The patient is an 8-year-old girl with a history of asthma and developmental delay. She complained of hip pain, and her pediatrician referred her to a pediatric orthopedist for consultation. Hip x-ray films were ordered; they revealed 3 round beads in the child's appendix.

A number of inflammatory diseases have been associated with an increased risk of atherosclerosis. Knoflach and colleagues report findings that support a link between allergic diseases, such as allergic rhinitis and asthma, and atherosclerosis. Their findings came from 2 studies: the Bruneck study, which included 826 men and women aged 40 to 70 years, and the Atherosclerosis Risk Factors in Male Youngsters (ARMY) study, which included 141 male participants aged 17 or 18 years.

The influenza vaccine has been used for many years to control outbreaks of influenza, and its role in reducing morbidity and mortality is widely appreciated among health care professionals and patients alike. The panic that occurred in 2004 after announcements of a vaccine shortage bears testimony to the importance placed on this approach to influenza prevention and control.

Abstract: Shortness of breath is a common complaint associated with a number of conditions. Although the results of the history and physical examination, chest radiography, and spirometry frequently identify the diagnosis, dyspnea that remains unexplained after the initial evaluation can be problematic. A stepwise approach that focuses further testing on the most likely diagnoses is most effective in younger patients. Early bronchoprovocation challenge testing is warranted in younger patients because of the high prevalence of asthma in this population. Older patients require more complete evaluation because of their increased risk of multiple cardiopulmonary abnormalities. For patients who have multiple contributing factors or no clear diagnosis, cardiopulmonary exercise testing can help prioritize treatment and focus further evaluation.

A 45-year-old man was referred to our pulmonary clinic for progressive dyspnea and worsening asthma. His shortness of breath had been worsening over the past 2 years. He denied fever, weight loss, and other systemic complaints.

Abstract: The manifestations of indoor mold-related disease (IMRD) include irritant effects, such as conjunctivitis and rhinitis; nonspecific respiratory complaints, such as cough and wheeze; hypersensitivity pneumonitis; allergic fungal sinusitis; and mycotoxicosis. The diagnosis of IMRD depends on eliciting an accurate history and excluding preexisting pathology that would account for the patient's symptoms. Laboratory tests, imaging studies, and spirometry can play an important role in ruling out other diagnoses, such as allergic or nonallergic rhinitis, asthma, and pneumonia. The diagnosis of IMRD also involves integrating the results of immunologic, physiologic, and imaging studies with the results of indoor air-quality studies. (J Respir Dis. 2005;26(12):520-525)

An asymptomatic acneiform eruption; persistent, mildly pruritic papules; a pustular rash that resists antibiotics--can you identify the disorders pictured here?

The diagnosis of cystic fibrosis (CF) is typically made in childhood. However, there is increasing evidence that a mild and atypical form of this disease can present in adulthood. The author describes a patient who received the diagnosis of CF when she was 74 years old.
