TL;DR: It was found that a significant proportion of subjects who were judged to be two-dimensional perceivers on Hudson's test built three-dimensional models; the validity of Littlejohn's and Du Toit's explanation is questioned.
Abstract: Hudson's Pictorial Perception test and a construction test, in which subjects were asked to construct geometrical models shown on pictures, were administered to Central African schoolboys and domestic servants. It was found that a significant proportion of subjects who were judged to be two-dimensional perceivers on Hudson's test built three-dimensional models; the validity of Littlejohn's and Du Toit's explanation is therefore questioned. The models thus obtained were, however, often both distorted and oddly oriented. Domestic servants were found to be more often two-dimensional perceivers than schoolboys; it appears therefore that passive exposure to pictorial material can play only a minor role in determining pictorial depth perception. It is suggested, on the basis of the results obtained, that the two-dimensional responses on Hudson's test may be due, at least in part, to the subjects' inability to organize the material presented in the test pictures.

Abstract: Background: In line with the Global trend to improve malaria control efforts a major campaign of insecticide treated net distribution was initiated in 1999 and indoor residual spraying with DDT or pyrethroids was reintroduced in 2000 in Zambia In 2006, these efforts were strengthened by the President’s Malaria Initiative This manuscript reports on the monitoring and evaluation of these activities and the potential impact of emerging insecticide resistance on disease transmission Methods: Mosquitoes were captured daily through a series of 108 window exit traps located at 18 sentinel sites Specimens were identified to species and analyzed for sporozoites Adult Anopheles mosquitoes were collected resting indoors and larva collected in breeding sites were reared to F1 and F0 generations in the lab and tested for insecticide resistance following the standard WHO susceptibility assay protocol Annual cross sectional household parasite surveys were carried out to monitor the impact of the control programme on prevalence of Plasmodium falciparum in children aged 1 to 14 years Results: A total of 619 Anopheles gambiae sl and 228 Anopheles funestus sl were captured from window exit traps throughout the period, of which 203 were An gambiae malaria vectors and 14 An funestus ss In 2010 resistance to DDT and the pyrethroids deltamethrin, lambda-cyhalothrin and permethrin was detected in both An gambiae ss and An funestus ss No sporozoites were detected in either species Prevalence of P falciparum in the sentinel sites remained below 10% throughout the study period Conclusion: Both An gambiae ss and An funestus ss were controlled effectively with the ITN and IRS programme in Zambia, maintaining a reduced disease transmission and burden However, the discovery of DDT and pyrethroid resistance in the country threatens the sustainability of the vector control programme

TL;DR: Interim findings show that country coordinating mechanisms (CCMs) are country-level partnerships, which were formed quickly to develop and submit grant proposals to the Global Fund, were often ineffective at representing their constituencies and encountered obstacles in participating in CCM processes.

TL;DR: G gaps in care are described that result in patients with PNES not having adequate access to healthcare provisions in less developed countries.
Abstract: An international consensus clinical practice statement issued in 2011 ranked psychogenic nonepileptic seizures (PNES) among the top three neuropsychiatric problems. An ILAE PNES Task Force was founded and initially charged with summarizing the current state of the art in terms of diagnosis and treatment, resulting in two publications. The first described different levels of diagnostic certainty. The second summarized current knowledge of management approaches. The present paper summarizes an international workshop of the ILAE PNES Task Force that focused on the current understanding and management of PNES around the world. We initially provide a knowledge update about the etiology, epidemiology, and prognosis of PNES-in adults and in special patient groups, such as children, older adults, and those with intellectual disability. We then explore clinical management pathways and obstacles to optimal care for this disorder around the world by focusing on a number of countries with different cultural backgrounds and at very different stages of social and economic development (United Kingdom, U.S.A., Zambia, Georgia, China, and Japan). Although evidence-based methods for the diagnosis and treatment of PNES have now been described, and much is known about the biopsychosocial underpinnings of this disorder, this paper describes gaps in care (not only in less developed countries) that result in patients with PNES not having adequate access to healthcare provisions. A range of challenges requiring solutions tailored to different healthcare systems emerges. Continued attention to PNES by the ILAE and other national and international neurologic, psychiatric, and health organizations, along with ongoing international collaboration, should ensure that patients with PNES do not lose out as healthcare services evolve around the world.
