A 67-year-old man with a history of hypertension and chronic lymphocytic leukemia (CLL), the latter diagnosed 10 years earlier, in remission until recently, presented with complaints of weight loss, not eating much, lethargy, and shortness of breath.

Which of the following statements regarding the chest radiograph is most accurate? 1. The chest radiograph shows basal predominant linear opacities suggesting fibrosis 2. The chest radiograph shows large lung volumes with cystic change 3. The chest radiograph shows multifocal ground-glass opacity and cavitary consolidation 4. The chest radiograph shows multifocal ground-glass opacity and consolidation associated with linear and reticular abnormalities 5. The chest radiograph shows multiple nodule

Pneumomediastinum from nasal insufflation of cocaine

Chest pain is a common presenting symptom of cocaine users to the emergency department that requires a thorough work up. Pneumomediastinum is an uncommon complication of cocaine abuse that occurs more commonly when cocaine is smoked, but can also occur when cocaine is nasally insufflated. Our case report presents a patient with pneumomediastinum secondary to cocaine insufflation and reviews the necessary diagnostic tests that must be performed to rule out secondary pneumomediastinum, a severe life-threatening condition. Our case is unique, as it is one of a few reported cases of pneumomediastinum occurring after the use of intranasal cocaine

First case of childhood Takayasu arteritis with renal artery aneurysms

Takayasu arteritis is a large vessel systemic granulomatous vasculitis characterized by stenosis or obliteration of large and medium sized arteries. It commonly involves elastic arteries such as the aorta and its main branches. Renal artery involvement is rare and has not been reported in a child. We report a 12-year-old boy with Takayasu arteritis who developed severe hypertension, proteinuria, microscopic hematuria and renal dysfunction. Conventional angiography demonstrated aneurysms of both renal arteries and multiple microaneurysms of the superior mesenteric artery. This case report illustrates that the children with Takayasu arteritis can develop renal involvement resulting in hematuria, proteinuria and even renal failure

Pulmonary cystic disease in HIV positive individuals in the Democratic Republic of Congo: three case reports

Pulmonary emphysema and bronchiectasis in HIV seropositive patients has been described in the presence of injection drug use, malnutrition, repeated opportunistic infections, such as Pneumocytis jirovici pneumonia and Mycobacterium tuberculosis infection, and has been linked to the presence of HIV virus in lung tissue. Given the high burden of pulmonary infections and malnutrition among people living with HIV in resource poor settings, these individuals may be at increased risk of developing pulmonary emphysema, potentially reducing the long term benefit of antiretroviral therapy (ART) if initiated late in the course of HIV infection
