Background: The human immunodeficiency virus (HIV) continues to be a major cause of maternal and infant mortality and morbidity in sub-Saharan Africa. Prevention of mother-to-child transmission of HIV (PMTCT) strategies have proven effective in decreasing the number of children infected in utero, intrapartum and during the breastfeeding period. This qualitative study explores knowledge and perceptions of HIV amongst pregnant women, healthcare workers' experiences of the national PMTCT services, and barriers to PMTCT, during a period of programme scale-up in urban Guinea-Bissau (2010-11). Methods: In-depth interviews were undertaken amongst 27 women and 19 key informants at local antenatal clinics and the national maternity ward in Bissau, Guinea-Bissau. Results: Amongst women who had been tested for HIV, awareness and knowledge of HIV and PMTCT remained low. Testing without informed consent was reported in some cases, in particular when the test was performed around the time of delivery. Possible drivers of inadequate counselling included lack of confidentiality, suboptimal healthcare worker training, lack of time, and perceived occupational risk. Demand-side barriers to PMTCT included lack of HIV and PMTCT knowledge, customary and cultural beliefs associated with HIV and ill-health, HIV stigma and discrimination, and fear of partnership dissolution. Conclusions: Socio-cultural and operational challenges, including HIV testing without informed consent, present significant barriers to the scale-up of PMTCT services in Bissau. Strengthening local capacity for effective counselling and testing in the antenatal setting is paramount. Further research into local customary beliefs relating to HIV is warranted.

Objectives To assess uptake of community-based capillary thyroid stimulating hormone (TSH) screening in Scotland and determine the optimal frequency of screening, the justification for preschool screening and strategies for treatment. Methods Subjects with Down's syndrome aged 1–19 years underwent capillary TSH measurement. Clinical and biochemical data were collected using proformas. Results 5742 capillary TSH tests were performed on 1329 children in 1997–2009, increasing from 183 children from two health boards tested in 1997 to 630 from 13 health boards tested in 2009. Of 132 children referred by the screening laboratory with elevated capillary TSH, 98 (M:F ratio 1:1.2, median (range) age 8.9 (0.9–17.9) years) had adequate documentation and 76 had thyroid dysfunction (defined as venous TSH >6 mU/l), giving a prevalence of not less than 5.7%. Fifty-six (57%) had tested negative during the previous year, 8 (8%) tested positive on their first screening test and 23/67 (34%) were thyroid peroxidase autoantibody negative on initial venous blood. Two of the 13 (13%) preschool children were severely hypothyroid (venous TSH 71 and 283 mU/l). Of patients with venous TSH 6–10.9 (n=27), 11.0– 20.9 (n=25) and ≥21.0 mU/l (n=24) following referral, initial/subsequent treatment with thyroxine was given in 3/8, 15/5 and 21/1, respectively. Conclusion Capillary TSH screening in Down's syndrome is eminently feasible and should be performed annually from 1 year of age. Nearly all subjects with initial venous TSH ≥11.0 mU/l will require thyroxine treatment but most with TSH 6–10 mU/l only require surveillance initially. [ABSTRACT FROM AUTHOR]
