Prevalence of plasmodium slide positivity among the children treated for malaria, Jhangara, Sindh

Objective: The aim of the study was to estimate the prevalence of malaria amongst the children with fever or history of fever.SETTING: Rural Health Centre (RHC), Jhangara, a town near the Manchhar Lake in Taluka Sehwan, District Dadu, Sindh.SUBJECTS: Four hundred and thirty eight children of 6 months to 10 years of age, who attended above described RHC during August through October 1997.Methods: A Sindhi-translated standard questionnaire was used to record symptoms and duration of child\u27s illness. Each child was physically examined, had their axillary temperature measured; and blood samples were collected from which Giemsa stained thick and thin blood films were examined for presence of Plasmodium parasites.Results: The median age of the studied children was 24 months and 57% (250/438) were boys. Fifty three percent (231) of the study subjects were from Jhangara Town, 40% (177) and 7% (30) came from other villages and villages near to the Manchhar Lake respectively. The prevalence of Plasmodium slide positivity was 5.9% (26/438). Among Plasmodium slide positive children, 65% (17/26) were positive for P. falciparum and 35% (9/26) for P. vivax. Among the P. falciparum positive children, 88% (15/26) had scanty (MP, 1-10/100 fields) and 12% (2/26) had moderate density (MP, 10-100/100 fields) of infection. Seventeen percent (6/30) of the children from villages close to Manchhar Lake were Plasmodium slide positive compared to 7% (17/53) and 3% (5/177) from Jhangara town and other villages respectively. Cough, diarrhea, abdominal distention and vomiting were the commonly reported symptoms among the children of all ages at the time of interview. Guardians reported fever as part of the illness in all children, although during physical examination only 128 (29%) had axillary temperature \u3e or = 37.5 degrees C. Pallor as an indicator for anemia, rash and prickly heat were the major recorded observations.CONCLUSION: The Prevalence of Plasmodium positivity was higher in children who attended from villages close to Manchhar lake, therefore especial measure needs to be considered for this area. In addition, the health care workers in rural Sindh need to adopt appropriate guidelines to differentiate the clinical malarial patients from patients with other potential infectious diseases, which may need other treatment

Confirmed malaria cases among children under five with fever and history of fever in rural western Tanzania

The World Health Organization recommends that malaria treatment should begin with parasitological diagnosis. This will help to control misuse of anti-malarial drugs in areas with low transmission. The present study was conducted to assess the prevalence of parasitologically confirmed malaria among children under five years of age presenting with fever or history of fever in rural western Tanzania. A finger prick blood sample was obtained from each child, and thin and thick blood smears were prepared, stained with 10% Giemsa and examined under the light microscope. A structured questionnaire was used to collect each patient's demographic information, reasons for coming to the health center; and a physical examination was carried out on all patients. Fever was defined as axillary temperature ≥ 37.5°C. A total of 300 children with fever or a history of fever (1 or 2 weeks) were recruited, in which 54.3% (163/300, 95%CI, 48.7-59.9) were boys. A total of 76 (76/300, 25.3%, 95%CI, 22.8 - 27.8) of the children had fever. Based on a parasitological diagnosis of malaria, only 12% (36/300, 95%CI, 8.3-15.7) of the children had P. falciparum infection. Of the children with P. falciparum infection, 52.7% (19/36, 95%CI, 47.1-58.3) had fever and the remaining had no fever. The geometrical mean of the parasites was 708.62 (95%CI, 477.96-1050.62) parasites/μl and 25% (9/36, 95%CI, 10.9 -- 39.1) of the children with positive P. falciparum had ≥ 1001 parasites/μl. On Univariate (OR = 2.13, 95%CI, 1.02-4.43, P = 0.044) and multivariate (OR = 2.15, 95%CI, 1.03-4.49) analysis, only children above one year of age were associated with malaria infections. Only a small proportion of the children under the age of five with fever had malaria, and with a proportion of children having non-malaria fever. Improvement of malaria diagnostic and other causes of febrile illness may provide effective measure in management of febrile illness in malaria endemic areas

Decreasing NF-κB Expression Enhances Odontoblastic Differentiation and Collagen Expression in Dental Pulp Stem Cells Exposed to Inflammatory Cytokines

Inflammatory response in the dental pulp can alter the collagen matrix formation by dental pulp stem cells and lead to a delay or poor healing of the pulp. This inflammatory response is mediated by cytokines, including interleukin-1β and tumor necrosis factor-α. In this study, it is hypothesized that suppressing the actions of these inflammatory cytokines by knocking down the activity of transcription factor Nuclear Factor–κB will lead to dental pulp stem cell differentiation into odontoblasts and the production of collagen. Here, the role of Nuclear Factor–κB signaling and its reduction was examined during odontogenic behavior in the presence of these cytokines. The results showed a significant increase in Nuclear Factor–κB gene expression and p65 protein expression by interleukin-1β and tumor necrosis factor-α. Nuclear Factor–κB activation in the presence of these cytokines decreased significantly in a dose-dependent manner by a Nuclear Factor–κB inhibitor (MG132) and p65 siRNA. Down-regulation of Nuclear Factor–κB activity also enhanced the gene expression of the odontoblastic markers (dentin sialophosphoprotein, Nestin, and alkaline phosphatase) and displayed an odontoblastic cell morphology indicating the promotion of odontogenic differentiation of dental pulp stem cells. Finally, dental pulp stem cells exposed to reduced Nuclear Factor–κB activity resulted in a significant increase in collagen (I)-α1 expression in the presence of these cytokines. In conclusion, a decrease in Nuclear Factor-κB in dental pulp stem cells in the presence of inflammatory cytokines enhanced odontoblastic differentiation and collagen matrix formation.The open access fee for this work was funded through the Texas A&M University Open Access to Knowledge (OAK) Fund

Evaluation of a water, sanitation, and hygiene education intervention on diarrhoea in northern Pakistan.

OBJECTIVE: Inadequate water and sanitation services adversely affect the health and socioeconomic development of communities. The Water and Sanitation Extension Programme (WASEP) project, undertaken in selected villages in northern Pakistan between 1997 and 2001, was designed to deliver an integrated package of activities to improve potable water supply at village and household levels, sanitation facilities and their use, and awareness and practices about hygiene behaviour. METHODS: A case-control study was conducted during July-September 2001 to evaluate whether, after selected confounders were controlled for, children aged <6 years with diarrhoea were more or less likely to reside in villages that participated in the project than in villages that did not participate. Descriptive and logistic regression analyses were performed. FINDINGS: Children not living in WASEP villages had a 33% higher adjusted odds ratio for having diarrhoea than children living in WASEP villages (adjusted odds ratio, 1.331; P<0.049). Boys had 25% lower odds of having diarrhoea than girls (adjusted odds ratio, 0.748; P<0.049). A 2.6% decrease was found in the odds of diarrhoea for every yearly increase in the mother's age (adjusted odds ratio, 0.974; P<0.044) and a 1.4% decrease for every monthly increase in the child's age (adjusted odds ratio, 0.986; P<0.001). CONCLUSIONS: The findings in this study may help refine the approach to future water, sanitation, and hygiene initiatives in northern Pakistan. The integrated approach taken by WASEP, which incorporates engineering solutions with appropriate education to maximize facility usage and improve hygiene practices, is a useful example of how desired health benefits can be obtained from projects of this type

![Figure][1] Diverse types of cortical interneurons (INs) mediate various kinds of inhibitory control mechanisms to balance and shape network activity. Distinct IN subtypes develop uniquely organized axonal arbors that innervate different subcellular compartments of excitatory principal neurons (PNs), which critically contribute to determining their output properties. However, it remains poorly understood how they establish this peculiar axonal organization and synaptic connectivity during development. Here, taking advantage of genetic labeling of IN progenitors, we examined developmental processes of axonal arbors and synaptic connections formed by murine chandelier cells (ChCs), which innervate axon initial segments (AISs) of PNs and thus powerfully regulate their spike generation. Our quantitative analysis by light microscopy revealed that ChCs overgrow and subsequently refine axonal branches as well as varicosities. Interestingly, we found that although a significant number of axonal varicosities are formed off AISs in addition to on AISs, presynaptic markers are predominantly colocalized with those on AISs throughout development. Immunoelectron microscopic (IEM) analysis also demonstrated that only varicosities apposed to AISs contain presynaptic profiles. These results suggest that subcellular synapse specificity of ChCs is genetically predetermined while axonal geometry is shaped through remodeling. Molecular cues localized at AISs may regulate target recognition and synapse formation by ChCs. [1]: pending:ye
