Atrial Fibrillation

Abstract: The coexistence of asthma and obstructive sleep apnea (OSA) in a given patient presents a number of diagnostic and treatment challenges. Although the relationship between these 2 diseases is complex, it is clear that risk factors such as obesity, rhinosinusitis, and gastroesophageal reflux disease (GERD) can complicate both asthma and OSA. In the evaluation of a patient with poorly controlled asthma, it is important to consider the possibility of OSA. The most obvious clues are daytime sleepiness and snoring, but the definitive diagnosis is made by polysomnography. Management of OSA may include weight loss and continuous positive airway pressure (CPAP). Surgical intervention, such as uvulopalatopharyngoplasty, may be an option for patients who cannot tolerate CPAP. Management may include specific therapies directed at GERD or upper airway disease as well as modification of the patient's asthma regimen. (J Respir Dis. 2005;26(10):423-435)

A 62-year-old African American woman was brought to the emergency department (ED) after the sudden onset of slurred speech and weakness in her left arm and leg. Her medical history included hypertension, insulin-dependent diabetes, and congestive heart failure.

A 74-year-old man, who had been aware of a gradual increase in hat size over the past 3 years, complained of a mild headache and backache. His serum phosphatase level was 1,475 U/L (upper normal limit, 120 U/L). Skull films showed calvarial enlargement caused by thickening of the cortical tables, radiolucency in the frontal and occipital regions, and patchy osteosclerosis that produced a cotton-wool appearance.

Having suffered progressive shortness of breath for 2 years, a 35-year-old man was eventually hospitalized. The patient's dyspnea had worsened over the past year, but he had neither chest pain nor palpitations. His primary care physician first noticed finger clubbing 8 months ago.

A 69-year-old woman was admitted to the hospital with wheezing and dyspnea. She also complained of hoarseness and slight dysphagia that had caused a loss of 12 lb during the past 4 months. The patient had been treated for bronchial asthma as an outpatient, but the worsening episodes of wheezing were not being controlled by bronchodilator therapy.

A 63-year-old man was given oral celecoxib, 100 mg bid, for shoulder pain. Three days later, a pruritic rash appeared on his back, then spread to the chest, lower legs, and face. He stopped the celecoxib on his own and self-administered diphenhydramine for the pruritus. The rash and itch persisted, which prompted the patient to seek medical care. He had no respiratory symptoms.

A 45-year-old man with a history of congestive heart failure presented with cough and dyspnea. A chest roentgenogram showed loculated pleural effusion in the horizontal fissure of the right lung, and a CT scan revealed pleural-based density in that lung.

For the past 6 weeks, a 72-year-old woman with a history of ovarian cancer had had intensifying dyspnea. Initially, she thought her breathing problem was caused by progressive congestive heart failure.

A 65-year-old woman with a long history of hypertension treated with metoprolol and felodipine complained of dizziness, headache, nausea, and vomiting of acute onset. Her blood pressure was 220/110 mm Hg. She was drowsy and unable to stand or walk.

A 48-year-old woman was admitted to the hospital with deep venous thrombosis of the right leg. She had a history of non-Hodgkin lymphoma, which was in remission. The patient had been a heavy smoker for many years.

For 2 days, a 79-year-old man with a history of congestive heart failure experienced abdominal pain, diarrhea, and dark red rectal bleeding. The pain was localized to the left lower quadrant.

A 64-year-old woman with a history of diabetes, hypertension, and lymphoma was admitted to the hospital with a dull headache, conjunctival congestion, and slight dyspnea. Her pulse rate was 96 beats per minute; blood pressure, 146/68 mm Hg; and respiration rate, 22 breaths per minute. She also had increased jugular venous distention; cardiovascular and chest examination findings were normal. Edema of both arms and dilated blood vessels on the anterior chest wall were noted.

A 72-year-old woman had complained of shortness of breath for the past week. A CT scan showed a large filling defect in the left main pulmonary artery (Figure A, thin arrows) that extended into both the upper and lower branches. Another filling defect (not shown here) was seen along the posterior wall of the right main pulmonary artery, extending into the lower branch. These defects are compatible with pulmonary emboli.

A 72-year-old woman who had fallen and injured the left side of her chest came to the emergency department complaining of pain in that area. She was physically stable and not short of breath. A soft systolic murmur was heard over the left precordium; the lungs were clear. A posteroanterior chest film showed no rib fracture but it did show an enlarged heart and a large, calcified ventricular aneurysm.

A 65-year-old man presented with bluish toes and petechiae on his toes and feet 3 days after having undergone renal angiography. Bilateral pitting pedal edema was noted, and laboratory tests revealed proteinuria, eosinophilia, and an erythrocyte sedimentation rate (ESR) of 65 mm/h.

An 80-year-old man with a history of congestive heart failure, coronary artery disease, cardiomyopathy, and thoracic and abdominal aneurysms was taken to the emergency department because of mental status changes, back pain, and ecchymotic areas over his body. The ecchymoses started on his back 5 days before admission and spread to his abdomen.

Tan-pink acneiform lesions on the face of a 15-year-old girl had not responded to topical acne therapy. A 1 × 0.5-cm, elevated subcutaneous nodule was noted on the right lateral knee. The lesions on her face and knee had been present for 11 years. The family history was noncontributory.

A 97-year-old woman with a history of hypertension and a paraesophageal hiatal hernia presented with abdominal distention and shortness of breath. Three days earlier, she had fallen and sustained a hairline pelvic fracture; she was evaluated in the emergency department and given narcotics for the pain. Subsequently, the patient's abdomen became increasingly distended, and she had no bowel movement for 3 days.

An 82-year-old woman was admitted to the hospital with severe dilated cardiomyopathy. The condition was alcohol-induced and had been diagnosed about 12 years earlier. The patient was taking angiotensin-converting enzyme inhibitors and diuretics.

With a 1-year history of episodic wheezing, a 62-year-old woman (a smoker for the past 30 years) was being treated for bronchial asthma, but bronchodilator therapy did not control her symptoms. She was hospitalized with worsening dyspnea and a 4.5-kg (10-lb) weight loss over the past 3 months. There was no hemoptysis.

These orange-to-brown macules with red puncta, or cayenne pepper spots, are typical of Schamberg's disease (progressive pigmented purpuric dermatosis). The cause of this disorder is unknown, but it may be related to a cellular immune reaction or drug reaction.

An 82-year-old man with Alzheimer's disease and atrial fibrillation was referred for evaluation of a lesion present for an undetermined period. It was initially noted 1 week earlier, at his first office visit with a geriatrician.

Cirrhosis and ascites developed in a 52-year-old man with a history of chronic hepatitis C and ethanol abuse. He was hospitalized because of bleeding esophageal varices, which were successfully treated with elastic band ligation.

A 72-year-old man with a history of rheumatic heart disease presented with pulmonary congestion and syncope. Results of the cardiac examination suggested mitral stenosis and atrial fibrillation with a controlled ventricular response. Two-dimensional echocardi-ography revealed a large, free-floating ball thrombus (T) in the dilated left atrium and demonstrated rheumatic and severely stenotic mitral valve leaflets.

These collections of dilated vessels deep in the dermis and subcutaneous tissue are present at birth. They usually present as bluish or reddish lesions that are cystic, firm, and compressible. About 60% to 80% of cavernous hemangiomas undergo spontaneous involution, often with central clearing and fibrosis.

During a routine physical examination of a healthy 7-year-old African-American boy, this striking-and puzzling-hyperpigmentation was noted on his palms.

A 73-year-old man who had a history of long-standing essential hypertension, congestive heart failure, mild renal insufficiency, atrial fibrillation, and a mitral valve replacement presented with refractory hypertension. His medications included labetalol, irbesartan, and furosemide.

An 8-year-old boy was brought to his pediatrician for well-child care. On physical examination, an irregularly irregular heart rate was detected.

Dyspnea, orthopnea, and weight loss sent a 40-year-old woman for medical consultation. Fifteen years earlier, the patient had been nephrectomized because of left kidney lithiasis. There was no history of other symptoms or diseases.

For 2 months, a 31-year-old woman had had dyspnea and dull, continuous retrosternal pain. She was admitted to the hospital, and a helical CT scan of the thorax identified a saddle pulmonary embolism. An ultrasonogram revealed deep venous thrombosis (DVT) in the left leg. Intravenous heparin was given; the patient was discharged, and warfarin was prescribed.
