A 19 Year Old Male With HIV Presents With Diffuse Lymphadenopathy

Background In 1872, Moritz Kaposi first described an idiopathic multiple pigmented sarcoma of the skin;\u27\u27 now identified as Kaposi\u27s sarcoma (KS).\u27 While multiple forms ofKSexist, over9S% of the cases diagnosed in the US since 1981 are of the AIDS associated variety.2 Kaposi originally described KS as skin lesions that can progress to visceral involvement. However, in a small number of cases, KS can appear in the viscera without skin involvement. These alternate presentations of KS are difficult to diagnose; therefore, it is critical to recognize them when considering differential diagnoses, particularly in patients with HIV. Case Presentation An 18-year-old African American male with a history ofHIV presented with progressive worsening of diffuse and painful lymphadenopathy fore five weeks prior to admission. The patient was diagnosed with HIV in 2010 and due to insurance issues, was never treated with highly active antiretroviral therapy (HAART). His last CD4 count (approximately two weeks prior to admission) was 411 and he had no history of opportunistic infections. He first noticed swelling in his neck, under his armpits and in his groin five weeks prior, which had become progressively more painful. The patient denied fevers, chills or weight loss, but did report significant night sweats and episodes ofhemoptysis with dots. He denied shortness ofbreath or chest pain. He also denied recent travel, history of incarceration, homelessness or exposure to active tuberculosis infection

Rare Gram-Negative Sepsis in a Non-Ventilated Neutropenic Patient with AML

Case Report A 57-year-old man with history of hypertension, hyperlipidemia,and gout presented for evaluation of both a perioral infection and an infection in his right great toe from an injury on the beach at his shore house. The toe trauma was complicated by a massive hematoma and phlebitis, which required antibiotics. His primary care physician ordered basic laboratory studies thatshowed an anemia and thrombocytopenia. He was sent to a Hematology and Oncology specialist and subsequently directly admitted to Thomas Jefferson University Hospital for blood transfusion and further work-up. Upon further questioning, thepatient admitted to chills starting 2 weeks prior to admission, elevated temperatures, rigors, dizziness, weakness, shortness of breath and a weight loss of about 16 pounds over 1 month. He denied prolonged bleeding or easy bruising, but did admit to recurrent upper respiratory infections

Search for heavy resonances in the W/Z-tagged dijet mass spectrum in pp collisions at 7 TeV

A search has been made for massive resonances decaying into a quark and a vector boson, qW or qZ, or a pair of vector bosons, WW, WZ, or ZZ, where each vector boson decays to hadronic final states. This search is based on a data sample corresponding to an integrated luminosity of 5.0 fb 121 of proton\u2013proton collisions collected in the CMS experiment at the LHC in 2011 at a center-of-mass energy of 7 TeV. For sufficiently heavy resonances the decay products of each vector boson are merged into a single jet, and the event effectively has a dijet topology. The background from QCD dijet events is reduced using recently developed techniques that resolve jet substructure. A 95% CL lower limit is set on the mass of excited quark resonances decaying into qW (qZ) at 2.38 TeV (2.15 TeV) and upper limits are set on the cross section for resonances decaying to qW, qZ, WW, WZ, or ZZ final states
