The positive topline data from the phase 3 ACHIEVE-1 trial suggest the small molecule GLP-1 mimetic could compete with blockbuster weekly injectables for reducing weight, A1c.
Unusual Presentation of Pneumocystis carinii Pneumonia
September 14th 2005A previously healthy 51-year-old man presented with weight loss and poor appetite of 2 months' duration. He was heterosexual and had many sexual partners. Except for a temperature of 38.3°C (100.9°F) and left basal rhonchi, results of physical examination were normal. A chest radiograph and CT scan, as seen here, showed large cavitary lesions in the lower left lobe.
Pulmonary Embolism and Deep Venous Thrombosis
September 14th 2005For 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.
Cyclospora cayetanensis and AIDS
A 32-year-old Hispanic woman with AIDS presented with a 1-month history of diarrhea; abdominal bloating and cramps; loss of appetite; and pronounced fatigue, malaise, and weight loss. She had no fever or chills and was not vomiting. Her CD4+ cell count was 12/µL. Results of a routine microscopic examination of stool for ova and parasites were negative; an acid-fast stain of stool demonstrated oocytes of Cyclospora cayetanensis measuring 8.8 mm in diameter (pictured, magnification ×1,000). This is about twice the size of the Cryptosporidium parvum oocyte, which typically is 4 to 5 mm.
Pyoderma Gangrenosum: Three Cases
September 14th 2005The dark red plaques seen here developed rapidly under both arms of this markedly obese 43-year-old woman. The lesions spread concentrically, forming necrotic ulcerations with overhanging borders, and there was surrounding violaceous discoloration. No other areas of the patient's body were involved, and she was otherwise in good health.
Migrated Intracranial Aneurysm Clip
September 14th 2005A 53-year-old woman had complained of pain in the lower right quadrant of her abdomen for 1 year. She claimed that the pain intensified when she bent forward in a particular position but believed it was unrelated to food, bowel movements, or urination. There was no weight loss, vomiting, or melena. There was no family history of colon cancer or inflammatory bowel disease.
Adenocarcinoma of the Lung in a 67-Year-Old Man
September 14th 2005A 67-year-old man with a 5-month history of cough, shortness of breath, and pain in the left anterior chest wall sought medical evaluation. The patient denied fever, chills, and hemoptysis. He reported a recent weight loss of 25 lb. The patient had smoked cigarettes for 37 years.
Hepatic and Splenic Infarction in Systemic Lupus Erythematosus
September 14th 2005Systemic lupus erythematosus (SLE) was diagnosed in an 18-year-old man who presented with polyarthritis, fever, hypoxia, fatigue, anemia, neutropenia, and abnormal urinary sediment. A renal biopsy showed diffuse mesangial proliferative glomerulonephritis (World Health Organization class II). Serologic tests were positive for fluorescent antinuclear antibody (FANA), SS-A, SS-B, anti-Sm and anti-dsDNA antibodies, and rheumatoid factor; a direct Coombs' test result was positive as well.
The keys to diagnosing interstitial lung disease: Part 1
September 1st 2005Abstract: The idiopathic interstitial pneumonias (IIPs) are the most commonly diagnosed forms of interstitial lung disease. These diseases represent specific clinicopathologic entities characterized by varying degrees of lung parenchymal inflammation and fibrosis. While most patients present with chronic dyspnea and have evidence of restriction on pulmonary function testing, certain findings can help differentiate among the IIPs. For example, patients with idiopathic pulmonary fibrosis (IPF)--the most common IIP--commonly present in the sixth or seventh decade of life, while those with desquamative interstitial pneumonia or respiratory bronchiolitis with interstitial lung disease typically present in the third or fourth decade of life and have a history of smoking. IPF is characterized by usual interstitial pneumonia (UIP) on lung biopsy; a UIP pattern can also be identified by high-resolution CT. (J Respir Dis. 2005;26(9):372-378)
Case In Point: Exfoliative dermatitis: A presenting sign of lung cancer
September 1st 2005A 53-year-old man presented with a 3-day history of bilateral pain in the lower extremities. He also had a 3-month history of thickening and desquamation of skin, with associated itching, and a 5-lb (2.27-kg) weight loss. The skin changes initially appeared on the hands and subsequently became generalized.
