Abstract Chronic headache can be a presenting manifestation of Takayasu arteritis, although patients usually have other characteristic features. A thorough clinical assessment remains key in the evaluation of chronic headache.

Abstract In a patient with Collet‐Sicard syndrome and multiple myeloma, both extramedullary plasmacytomas and internal jugular vein‐sigmoid sinus thrombosis should be considered as they can coexist.

BackgroundOccult hepatitis B virus (HBV) infection (OBI) is a phase of HBV infection characterised by the presence of HBV DNA in the absence of detectable hepatitis B surface antigen (HBsAg). OBI is of concern in the HIV-infected due to high prevalence and risk of HBV reactivation. The prevalence and clinico-demographic characteristics of OBI in anti-retroviral therapy (ART) naïve HIV infected adults in Kenya is unknown.MethodsA cross sectional study carried was out at three sites in Kenya. HIV infected ART naïve adults were enrolled and demographic data collected. Blood samples were assayed for HBsAg, HBV DNA, alanine aminotransferase, aspartate aminotransferase, antibodies to hepatitis B surface antigen (anti-HBs) and hepatitis B core antigen (anti-HBc). Data on CD4 count, HIV viral load and platelet count were obtained from medical records.ResultsOf 208 patients, 199 (95.7%) did not report HBV vaccination, 196 (94.2%) were HBsAg negative, 119 (57.2%) had no HBV markers, 58 (27.9%) had previous HBV infection (anti-HBc positive) and 11 (5.3%) had OBI. All 11 (100%) OBI patients were anti-HBc positive. OBI patients comprised 19.0% of HBsAg negative, anti-HBc positive patients. There was no difference in clinico-demographic characteristics between the overt HBV, OBI and HBV negative patients.ConclusionThis was the first study on OBI in ART naïve HIV infected adults in Kenya. The lower OBI prevalence compared to other sub-Saharan African countries could be attributed to lower HBV exposure. Most patients were HBV unexposed and unimmunized, outlining the need to implement guideline recommended immunization strategies.

Benign recurrent intrahepatic cholestasis (BRIC) is a rare disorder characterised by recurrent episodes of cholestatic jaundice. First described in 1959, BRIC has been reported in patients all over the world including of African descent. Here, we describe a case of a 21-year-old male with recurring episodes of cholestatic jaundice where we diagnosed BRIC and terminated an episode with rifampicin. To our knowledge, this is the first case report of BRIC diagnosed in Africa.
