Acute hepatitis B in a hepatitis B vaccine non-responder.

Developing acute hepatitis B in immunocompetent non-responders to hepatitis B vaccination has been rarely reported. We report such a case in a 79 year old heterosexual male. There is evidence that tenofovir disoproxil/emtricitabine as primary prophylaxis can prevent acquisition of hepatitis B.

Acute recurrent lymphocytic meningitis in an immunocompetent HIV-positive African woman: Is it a Mollaret's meningitis or not?

We report a case of acute recurrent meningitis in an HIV-positive immunocompetent woman. In this case, a 34-year-old African woman with a known HIV infection presented with symptoms of acute meningitis. She was on combination antiretroviral therapy with abacavir, lamivudine, and nevirapine.

Isolated bilateral inguinal lymphadenopathy in the absence of other symptoms, due to LGV in known HIV-positive MSM: is it more common than we think?

The current resurgence of lymphogranuloma venereum (LGV) has drawn most attention to its potential for causing proctitis; however, this case highlights the need for awareness of LGV as a cause of isolated painful bilateral inguinal lymphadenopathy in a high-risk population and the importance of routine screening for LGV. We describe a case of a 37-year-old HIV positive man, in the population of men who have sex with men (MSM) who presented with bilateral enlarged inguinal lymph nodes and no other symptoms or signs. Urine nucleic acid amplification test was positive for chlamydia LGV-specific DNA.
