He reports that the finger “came out of place” at the middle knuckle (proximal interphalangeal[PIP] joint); he quickly put the finger back into place himself, quit playing, andiced it. About 2 hours later, he was unable tomove the finger without significant pain, andthe following day, inability to move it interferedwith his performance of tasks that requiredfine manual dexterity.

COPD: New TreatmentsChronic obstructive pulmonary disease(COPD) is the fourth leadingcause of chronic morbidity and mortalityin the United States.1 Its prevalenceand impact are increasing,and the World Bank/World HealthOrganization has projected that it willrank fifth in 2020 as a global burdenof disease.2,3 The economic and publichealth impact of COPD is staggering,because this chronic conditionrequires long-term care, frequentoffice visits, and use ofemergency department and hospitalservices. Thus, there is a pressingneed to discover new therapies thatcontrol symptoms and prevent diseaseprogression.

Calcified Splenic CystA 38-year-old man found lying on the floor in his home was hospitalized because of alcohol intoxication. A chest radiograph showed a large calcified lesion in the left upper abdomen. A CT scan with intravenous contrast revealed a large, well-defined, cystic mass with mural calcification in the spleen. The CT findings were not consistent with a vascular malformation or echinococcal cyst-specifically, the mass was sharply demarcated, unilocular without septations, and round with a thin wall and attenuation similar to water. Urine Histoplasma antigen test results were negative.

Acute Suppurative Thyroiditis in a Patient With Aplastic AnemiaAcute suppurative thyroiditis (AST) is a rare inflammatorycomplication in patients with hematological malignancy.Infection spreads to the thyroid from a distant site throughthe bloodstream or the lymphatics. Defects such as persistentthyroglossal duct and pyriform sinus fistula are associatedwith the development of AST. Ultrasonography, bariumswallow testing, CT, and fine-needle aspiration are usedfor diagnosis. Treatment includes the administration ofparenteral antibiotics, drainage, and excision. We describea patient with aplastic anemia and bacteremic AST.[Infect Med. 2008;25:339-342]

Inferior Myocardial Infarction With Right Ventricular InvolvementRight Ventricular involvement in acute inferior MI is an independent predictor of major complications and in-hospital death, as this case demonstrates. While in-hospital prognosis after left ventricular infarction is directly related to the postinfarct LV ejection fraction, involvement of the right ventricle drastically alters that linear relationship.

How to differentiate from restrictive cardiomyopathy Recognizing constrictive pericarditis as a cause of shortness of breath key words: Constrictive pericarditis, Pericardial calcificationabstract: In the past, constrictive pericarditis was most often caused by tuberculosis. Today, however, it is more likely to be preceded by injury or trauma, infection, or previous cardiac surgery. Most patients with constrictive pericarditis present with dyspnea and have elevated jugular venous pressure. Other potential symptoms and signs include peripheral edema, abdominal fullness, hepatomegaly, ascites, and chest pain. Electrocardiography demonstrates nonspecific ST-segment and T-wave changes and generalized T-wave inversion or flattening. In many cases, chest radiography and CT reveal pericardial calcification, and echocardiography shows increased pericardial thickness and calcification. Treatment may include NSAIDs, corticosteroids, antibiotics, angiotensin-converting enzyme inhibitors, and diuretics. Surgery is the treatment of choice for chronic disease, and pericardiectomy is typically effective. (J Respir Dis. 2007;28(2):49-56)

Economic Evaluation of a Prior Authorization Program for Biologic Response ModifiersSpecialty medications constitute the fastest-growing segment of drug spending under the pharmacy benefit. This study evaluated the impact of a specialty pharmacy prior authorization (PA) program on prescription drug costs for biologic response modifiers (BRMs) used in the treatment of persons with rheumatoid arthritis, juvenile rheumatoid arthritis, Crohn disease, ankylosing spondylitis, psoriatic arthritis, psoriasis, and other spondyloarthropathies. A retrospective, case-control, one-to-one matching approach based on patient age, sex, and client characteristics was used. Case clients were enrolled in the specialty pharmacy PA program from January 1 through December 31, 2005. The control group consisted of clients who were not enrolled in the program during this time. The average costs per eligible member per month (PMPM), for the total, plan, and member were $1.32, $1.29, and $0.03, respectively, in the case group, and $1.44, $1.41, and $0.03, respectively, in the control group. Clients who implemented the specialty pharmacy PA program for BRMs saved an estimated total cost of $0.12 PMPM. Implementing a specialty pharmacy PA program reduced BRM costs.

Case In Point: Acute eosinophilic pneumonia in a 19-year-old manThe authors describe a case of acute eosinophilic pneumonia (AEP) that occurred in a previously healthy young man. The presentation was similar to that of acute respiratory distress syndrome (ARDS), and the diagnosis was established by bronchoalveolar lavage (BAL). The authors note that it is important to recognize the subset of patients with AEP who present with an ARDS-like picture, especially since corticosteroids are very effective in this setting.

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. This case describes an unusual presentation of a rare disease (malignant peripheral nerve sheath tumor) mimicking a submassive PE.
