In 2009, WHO’s Second International Conference on Buruli Ulcer Control and Research resolved to strengthen the capacity of national laboratories to confirm cases of the disease, but advised that “efforts are still needed to develop simple diagnostic tools usable in the field as well as disabilit...y prevention methods”.
In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer

For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified

Au cours de la dernière décennie, les données de séquençage génétique des agents pathogènes ont gagné en importance et contribuent désormais de façon déterminante à la détection et à la maîtrise des flambées de maladies infectieuses, en facilitant la mise au point de ...produits de diagnostic, de médicaments et de vaccins et en guidant lesactivités de riposte aux flambées(1-11). L’émergence du nouveau coronavirus, par la suite désigné « coronavirus 2 du syndrome respiratoire aigu sévère » (SARS-CoV-2), a encore accentué l’importance des données de séquençage génétique.

n the countries of the Region of the Americas, there are different forms of organization of health services at the first level of care. Some countries include certain laboratory, dental and diagnostic imaging practices in the first level of care, while other countries centralize these practices in t...he second and third levels of care. Consequently, so that the List of Priority Medical Devices (LPMD) could be adapted to these different forms of organization of health systems in the region of the Americas, modular lists were developed that complement the main list. In this way, to use the LPMD, only those modules that are planned to be offered in a first-level care center are selected, and it is those lists that are analyzed.

Le présent document vise à fournir des orientations provisoires sur la mesure du périmètre crânien, les normes de croissance, l’évaluation clinique et les examens requis pour établir un diagnostic de microcéphalie et déterminer si elle s’accompagne d’anomalies neurologiques.
Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Research indicates that family reaction to the birth of a disabled child changes according to the type of disability and the child's diagnostic category. The differences are probably an indirect consequence of anticipated or actual reactions by those ...surrounding the disabled child and the family, in addition to parental reactions. Many researchers have recently mentioned the positive coping and functioning of many families with developmentally disabled children. In the past there was a tendency to emphasize issues of illness and pressures, spousal strain and maladjustment within the family, while presently they are replaced with questions concerning positive adjustment, satisfaction, acceptance, and spousal harmony. Rather than perceiving the family as a helpless victim, it is perceived as a unit that adapts by a process of structuring. Professionals must acknowledge the importance of the family, this change towards a positive attitude towards disability and that the controls decisions concerning the disabled child and the family.
