Prevention of mother to child transmission of HIV infection in Pacific countries

Introduction: A generalized epidemic of HIV infection has been evolving in Papua New Guinea over the last decade, whereas in other Pacific Island countries and territories (PICT) HIV transmission has generally been less widespread. Programmes to detect HIV infection in pregnant women and to prevent mother to child transmission (MTCT) during either delivery or breast‐feeding can decrease the incidence of infection in infants. The limited health infrastructure present in some PICT may delay the implementation of effective programmes to decrease MTCT of HIV. Methods: We used a standardized questionnaire to survey health‐care providers in 22 PICT for information on the epidemiology of HIV infection and strategies used during 2004 to prevent MTCT of HIV infection in their country. We supplemented these survey responses with data obtained from regional organizations supporting national responses to HIV. Results: We obtained responses from 21 PICT. The reported prevalence of known HIV infection was >150 per 100 000 persons in Papua New Guinea, approximately 100 per 100 000 persons in French Polynesia, Guam, New Caledonia and Tuvalu and <50 per 100 000 persons in the remaining 14 PICT. Other than in Papua New Guinea, where an estimated 500 pregnant women had HIV infection diagnosed in 2004, reported HIV infection among pregnant women was rare. Ten PICT reported that an HIV antibody test was offered as a routine component of antenatal care and 11 reported that antiretroviral medications were available for the prevention of MTCT of HIV infection. Conclusion: The prevalence of HIV infection differs greatly between PICT with a varying risk of MTCT of HIV infection. Successful prevention of MTCT of HIV infection throughout the PICT will require improved uptake of antenatal HIV antibody testing and better access to antiretroviral medications.     

Meconium peritonitis presenting as abdominal calcification: three cases with different pathology

Intra-abdominal calcification is uncommon in newborns and has several causes of which meconium peritonitis is the most frequent. Three neonates with intra-abdominal calcification as a complication of meconium peritonitis are presented. The types of meconium peritonitis were cystic, meconium pseudocyst and meconium ascites. Two required surgical intervention. Meconium peritonitis should be considered in newborns with intra-abdominal calcification.     

Spatiotemporal mapping the neural correlates of acupuncture with MEG

Acupuncture is an ancient Eastern healing modality with putative therapeutic applications. Unfortunately, little is known about the central mechanisms by which acupuncture may exert its effects. In this study, 16 [corrected] healthy subjects were evaluated with magnetoencephalography (MEG) to map the location and timing of brain activity during low-frequency electroacupuncture (EA) and mechanical, noninsertive, sham acupuncture (SA) given at acupoint PC-6. Both EA and SA evoked brain responses that localized to contralateral primary somatosensory (SI) cortex. However, initial responses for EA peaked slightly earlier than those for SA and were located inferiorly within SI. Average equivalent current dipole strength was stronger (particularly at latencies >60 ms) for SA. These spatiotemporal differences between activations elicited by EA and SA are likely attributable to stimulus modality (electrical versus mechanical) and differences in the underlying somatosensory fibers transmitting these signals. The present data confirm that acupuncture modulates activity within somatosensory cortex, providing support for previous studies that suggest that the therapeutic effects of acupuncture are linked to SI modulation. Thus, MEG provides excellent spatiotemporal characterization of the somatosensory component of acupuncture, and future studies can contrast derived brain response parameters in healthy controls with those found in a diseased state.
