Abstract: Although excessive daytime sleepiness is most often simply the result of inadequate sleep, other causes must be considered as well. Common causes of daytime sleepiness include obstructive sleep apnea/hypopnea syndrome (OSAHS) and medication side effects. The differential diagnosis also includes narcolepsy and restless legs syndrome (RLS). In many cases, the answers to a few simple questions can provide the necessary clues to the diagnosis. Loud snoring is associated with OSAHS, while sudden muscle weakness triggered by intense emotion is consistent with narcolepsy. Referral for sleep evaluation is indicated to evaluate for OSAHS, narcolepsy, RLS, and idiopathic hypersomnia. Methods of measuring daytime sleepiness include the Multiple Sleep Latency Test and the Epworth Sleepiness Scale. (J Respir Dis. 2005;26(6):253-259)
Abstract: Elderly persons with active tuberculosis may present with the classic features, such as cough, hemoptysis, and fever, but some patients present with less typical signs, such as hepatosplenomegaly, liver function abnormalities, and anemia. A high index of suspicion is required when a patient presents with cough or pneumonia unresponsive to conventional therapy. Acid-fast smear and mycobacterial culture of a sputum specimen are recommended for diagnosis. For an elderly patient who tests positive with purified protein derivative, 9 months of isoniazid prophylaxis is recommended. For patients who are intolerant of isoniazid or have been exposed to or infected by an isoniazid-resistant strain, rifampin single-agent preventive therapy may be an effective alternative.

abstract: There is increasing evidence that close monitoring and early intervention lead to better outcomes in patients with cystic fibrosis. At each office visit, spirometry should be performed and sputum culture specimens should be obtained; if the patient cannot produce sputum, a throat culture can be done instead. New respiratory symptoms or other evidence of worsening lung disease should prompt antibiotic therapy, increased airway clearance, and adjunctive anti-inflammatory medication as appropriate. Close attention should be paid to the patient's diet, appetite, stooling pattern, and growth measurements. Adolescents should be given additional information about their medications and adjunctive therapies to encourage them to take on a larger role in their own care. (J Respir Dis.2006;27(7):298-305)
