Paget's Disease of BoneA serum alkaline phosphatase (ALP) level three times higher than normal, found on routine laboratory examination, prompted further evaluation of a 57-year-old man. At admission, his temperature was 36.8°C (98.2°F), blood pressure was 120/85 mm Hg, pulse rate was 90 beats per minute, and respiration rate was 19 breaths per minute. The physical examination was unrevealing, and the patient's personal and family medical histories were unremarkable.

Fibromyalgia Syndrome: Can It Be Treated?Treatment of fibromyalgia syndrome (FMS) is a challenge. However, most patients benefit from appropriate management. Essential to treatment are a physician's positive and empathetic attitude, continuous psychological support, patient education, patience, and a willingness to guide patients to do their part in management. Other important aspects involve addressing aggravating factors (eg, poor sleep, physical deconditioning, emotional distress) and employing various nonpharmacologic modalities (eg, regular physical exercise) and pharmacologic therapies. Drug treatment includes use of tricyclic medications alone or in combination with a selective serotonin reuptake inhibitor, and other centrally acting medications. Tender point injection is useful. It is important to individualize treatment. Management of FMS is both a science and an art.

Chylothorax: A review of current management strategiesABSTRACT: The most common causes of chylothorax are neoplasm-particularly lymphoma-and trauma. The usual presentingsymptom is dyspnea resulting from the accumulationof pleural fluid. The diagnosis of chylothorax is established bymeasuring triglyceride levels in the pleural fluid; a triglyceridelevel of greater than 110 mg/dL supports the diagnosis. The initialapproach to management involves chest tube drainage ofthe pleural space. The administration of medium-chain triglyceridesas a source of fat is often useful. If drainage remains unchanged,parenteral alimentation should be started. Surgicalintervention is indicated if conservative management is notsuccessful or if nutritional deterioration is imminent. If chylothoraxpersists after ligation of the thoracic duct, options mayinclude percutaneous embolization, pleuroperitoneal shunt,and pleurodesis. (J Respir Dis. 2008;29(8):325-333)

Acute Dyspnea:ABSTRACT: The rate at which acute dyspnea develops can point to its cause. A sudden onset strongly suggests pneumothorax (especially in a young, otherwise healthy patient) or pulmonary embolism (particularly in an immobilized patient). More gradual development of breathlessness indicates pulmonary infection, asthma, pulmonary edema, or neurologic or muscular disease. A chest film best identifies the cause of acute dyspnea; it can reveal pneumothorax, infiltrates, and edema. Pulmonary embolism is suggested by a sudden exacerbation of dyspnea, increased ventilation, and a drop in PaCO2. A normal chest radiograph reinforces the diagnosis of pulmonary embolism, which can frequently be confirmed by a spiral CT scan of the chest. Pneumonia can be difficult to distinguish from pulmonary edema. In this setting, bronchoalveolar lavage and identification of the infectious organism may be necessary to differentiate between the 2 disorders.

Case In Point: Peripheral nerve sheath tumor mimicking pulmonary embolismWe describe a case in which a patient received thrombolytic therapy after he presented with a clinical picture consistent with submassive pulmonary embolism (PE). Two months later, a malignant peripheral nerve sheath tumor was diagnosed, and the patient died with metastatic disease. The filling defect in the left main pulmonary artery originally interpreted as PE was in fact a tumor.
