AIDS-related mycoses: the way forward

The contribution of fungal infections to the morbidity and mortality of HIV-infected individuals is largely unrecognized. A recent meeting highlighted several priorities that need to be urgently addressed, including improved epidemiological surveillance, increased availability of existing diagnostics and drugs, more training in the field of medical mycology, and better funding for research and provision of treatment, particularly in developing countries.

Mothers’ access to supportive hospital services after the loss of a baby through stillbirth or neonatal death

Every year, 3-5% of pregnant mothers in South Africa lose their babies to a stillbirth or neonatal death. These mothers need adequate services to prevent complications in their grieving process. Most of these babies are lost in hospital settings, so the treatment medical staff provide is vital. This study examined mothers’ experiences of accessing hospital, religious, formal and social services after a stillbirth or neonatal death. An exploratory research design was used to conduct applied research. A semi-structured interview schedule was used with a sample of 15 mothers who had lost a baby in the last 5 years. The findings were analysed quantitatively and qualitatively. The primary focus of this article is the quantitative findings relating to hospital services. The sample was small and these results cannot be generalised, but some conclusions are reached and recommendations are made to service providers in hospitals working with mothers who have lost babies. Mothers generally experienced the support services from hospitals as inadequate, compared to what hospitals could offer. Mothers that receive support after the loss of a baby generally cope better. This support thus assists them in the grieving process. Hospital staff can be trained to provide these services. Opsomming In Suid-Afrika verloor 3-5% swanger moeders hulle babas deur stilgeboorte of neonatale dood. Hierdie moeders benodig voldoende dienste om komplikasies in die rouproses te verhoed. Die behandeling deur mediese personeel is uiters belangrik omdat die meeste van dié babas in ‘n hospitaalopset sterf. Hierdie studie het moeders se ervarings van die toeganklikheid van hospitaal-, godsdienstige, formele en sosiale dienste na die dood van hulle babas deur stilgeboorte of neonatale dood ondersoek. Toegepaste navorsing is met behulp van ‘n verkennende navorsingsontwerp gedoen. ‘n Semi-gestruktureerde onderhoudskedule is gebruik met ‘n steekproef van 15 moeders wat hulle babas in die vorige 5 jaar verloor het. Die bevindinge is kwantitatief en kwalitatief ontleed. Hierdie artikel fokus primêr op die kwantitatiewe bevindinge wat op hospitaaldienste van toepassing is. Die steekproef was klein en bevindinge kan nie veralgemeen word nie, maar gevolgtrekkings en aanbevelings word gemaak vir diensverskaffers in hospitale wat met moeders werk wat hul babas verloor het. Respondente het die ondersteuningsdienste by hospitale oor die algemeen as onvoldoende ervaar in vergelyking met dít wat hospitale behoort aan te bied. Moeders wat wel ondersteuning na die verlies van ‘n baba ontvang, funksioneer oor die algemeen beter. Die ondersteuning help hulle in die rouproses. Hospitaalpersoneel kan opgelei word om hierdie dienste te verskaf.

A comparison of the effects of citalopram and moclobemide on resting brain perfusion in social anxiety disorder

INTRODUCTION

The serotonin specific reuptake inhibitor (SSRI) citalopram and the reversible mono-amine oxidase-A inhibitor (RIMA) moclobemide have both been used successfully for the treatment of social anxiety disorder (SAD). In this study we investigate the effects of these compounds on resting brain function using single photon emission computed tomography (SPECT).

METHODS

Subjects meeting DSM-IV criteria for SAD underwent regional cerebral blood flow (rCBF) SPECT using Tc-HMPAO at baseline and after 8 weeks of treatment with either citalopram or moclobemide. Using statistical parametric mapping brain SPECT studies were analysed to determine the effects of treatment on rCBF, to compare the effects of citalopram and moclobemide, and to detect correlations between changes in rCBF and clinical response.

RESULTS

Subjects received citalopram (n=17) or moclobemide (n=14) as therapy. Subjects in both treatment groups demonstrated a significant improvement of SAD symptoms as measured by the Liebowitz Social Anxiety Scale total score. All subjects demonstrated a decrease in rCBF in the insulae post therapy. Subjects receiving citalopram had decreased superior cingulate rCBF after therapy compared to those receiving moclobemide.

CONCLUSION

Both SSRI's and RIMA's decreased rCBF in the insulae during treatment of SAD; an effect that may be consistent with the role of these regions in processing internal somatic cues evoked by emotional stimuli. Citalopram had a greater effect on superior cingulate perfusion, an effect that is consistent with evidence of high levels of 5-HT transporters in this region.
