Abstract: Our understanding of the pathobiology of pulmonary arterial hypertension (PAH) has evolved considerably over the past 2 decades, with increasing recognition of the important role that aberrant vasoproliferative responses play in conjunction with disordered vasoconstriction. Classification of the many forms of PAH into categories sharing a similar pathophysiology and clinical presentations help the practicing clinician approach a complex differential diagnosis. Noninvasive tests can be used to narrow this differential but must be applied with an appreciation for their limitations. Transthoracic echocardiography is the screening tool of choice; the workup should also include chest radiography and electrocardiography. However, right heart catheterization is ultimately required to establish the diagnosis. While PAH remains a progressive and generally fatal disease, existing therapies have a significant impact on survival and new therapeutic targets offer great hope for improving the prognosis.

A 23-year-old woman was referred to our interstitial lung disease (ILD) clinic with a diagnosis of LAM, a progressive cystic ILD that affects women of childbearing age. The patient had been a smoker since the age of 16, but she quit smoking about 2 months before the clinic visit, when she had a pneumothorax. At that time, she complained of sudden onset right-sided chest pain with shortness of breath for which she was admitted to her hometown hospital.
A 61-year-old woman presented with progressive dyspnea of 5 months' duration. She first noticed dyspnea while engaged in her usual daily activities, and it gradually progressed in severity. A primary care physician prescribed bronchodilators without relief. She was subsequently referred for a pulmonary evaluation.
A 20-year-old woman presented with a painless left facial mass that had slowly enlarged over the previous 2 years. There was no facial numbness or weakness. Her medical history was unremarkable, and there was no recent weight loss.
ABSTRACT: Only a small number of patients with celiac disease exhibit the textbook symptoms of malabsorptive diarrhea with steatorrhea, weight loss, and nutritional deficiencies. Others may present with a subclinical enteropathy, GI complaints without constitutional symptoms, persistent travelers' diarrhea, or extraintestinal manifestations alone. Be alert for suggestive signs, such as weight loss, skin lesions, oral aphthae, muscle atrophy, de-enamelization of the teeth, and vague GI symptoms, such as bloating. Helpful serologic tests include IgG and IgA antigliadin antibodies, enzyme tissue transglutaminase antibodies, antiendomysial antibodies, and total IgA. Typical endoscopic findings are mucosal atrophy, fissuring, and scalloping. In addition to a gluten-free diet, management encompasses repletion of vitamins and minerals, including iron, folate, calcium, and vitamin D; screening for thyroid disease and diabetes mellitus; bone densitometry and age-appropriate cancer screening; and pneumococcal vaccination.
In his recent editorial "Why We Need to Know the Limitations of Evidence-Based Medicine", Dr Gregory Rutecki questioned whether the findings of randomized controlled trials (RCTs) can be extrapolated to patients in primary care practices, who often have multiple comorbidities.
