Seroprevalence of Pediatric Malaria in Quetta,Balochistan, Pakistan

Background

Malaria is one of the most devastating protozoal diseases in under developing countries like Pakistan where health facilities are scarce. It is the second most frequently reported disease with 4.5 million suspected cases in Pakistan. The current study was designed to determine the incidence of pediatric malaria in Quetta, Balochistan.

Methods

The study was conducted at Children Hospital Quetta (CHQ) during July 2011march 2012. Blood samples were collected from 3418 clinically suspected and were evaluated using thin and thick blood films stained with Giemsa stain.

Results

Out of 3418 total of 230 (6.72%) children were found positive for any of the malarial parasitic infestation. Plasmodium vivax was observed to be more common 54.34% (n= 125/230) than P. falciparum 44.78% (n = 103/230). Male children were 65.21% (150/230) i.e. two times more commonly affected than female 34.78% (80/230) children. The prevalence among age groups was 7.41% (n = 89/1200) in preschool-aged children aged 1-5 years, 7.11% (n = 75/1054) in school-aged children aged 6—10 years while 6.78% (n = 46/678) in 11-15 years-old children, and 6.66% (n = 20/300) in >15 year-olds children. Peak prevalence was noted in summer and mild in winter. Mixed infection of (0.86%: 2/230) P. vivax and P. falciparum was also observed in two cases although no case of P. malariae or P. ovale infection was seen during entire study.

Conclusion

The results reflect the higher prevalence of malaria in Quetta, Pakistan that poses a significant health threat and requires urgent attention of high-ups to launch programme to control the disease in the area.     

Hospitalization due to varicella in the Netherlands

Background  

In the Netherlands, incidence of physician's consultations and hospitalizations for varicella is low compared to other countries. Better knowledge about the severity of varicella among Dutch hospitalized patients is needed. Therefore, a medical record research was conducted among hospitalized patients with diagnosis varicella.     

The effect of enteral supplementation of neutral and acidic oligosaccharides on the response to vaccinations in preterm infants

The Future Legal Environment

The application of visual material is becoming increasingly more prominent when presenting forensic evidence in contemporary courts. This paper examines how photographic evidence is used as a means of presenting facts relating to evidence and whether the concept of photographic truth actually exists and advances knowledge. This paper suggests that the obligatory telling of truth when presenting evidence should also extend into the showing of the truth when visual narratives become dominant within forensic evidence. It further challenges the notion that photographs, due to the mechanistic nature of the camera, produce naturally objective and independent evidence that reinforces the search for the truth. Faithful contextualisation of photographic evidence is essential when the reliability of this form of evidence is deliberated.     

The lipid profile in psoriasis: a controlled study

BACKGROUND: Psoriasis is an inflammatory dermatosis that is characterized with hyperproliferation of keratinocytes and inflammatory infiltration in the epidermis and dermis. The high prevalence of atherosclerosis has been reported in psoriatic patients. High serum lipid level has been suggested in the pathogenesis of this phenomenon. In this study, our purpose was to compare the lipid profile in psoriatic patients with non-affected persons. METHODS: This study was designed and conducted as a case-control assay with 50 cases in the patient and control groups, respectively. The lipid profile, including serum level of triglyceride, cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were assessed in both groups. RESULTS: The patient and control groups each consisted of 50 cases (39 male and 11 female). The serum triglyceride, cholesterol, and LDL was significantly higher in psoriatic patients (P < 0.05) but not for HDL (P = 0.29). CONCLUSION: This study, like previous assays, shows that high serum lipid level is significantly more common in psoriasis. This fact may be responsible for higher prevalence of cardiovascular accident in psoriatic patients. It may be useful to do early screening and treatment of hyperlipidaemia in psoriasis to prevent the atherosclerosis and its complications.     

Long term functioning in early onset psychosis: Two years prospective follow-up study

Background

Neuroimaging technology has afforded advances in our understanding of normal and pathological brain function and development in children and adolescents. However, noncompliance involving the inability to remain in the magnetic resonance imaging (MRI) scanner to complete tasks is one common and significant problem. Task noncompliance is an especially significant problem in pediatric functional magnetic resonance imaging (fMRI) research because increases in noncompliance produces a greater risk that a study sample will not be representative of the study population.

Method

In this preliminary investigation, we describe the development and application of an approach for increasing the number of fMRI tasks children complete during neuroimaging. Twenty-eight healthy children ages 9-13 years participated. Generalization of the approach was examined in additional fMRI and event-related potential investigations with children at risk for depression, children with anxiety and children with depression (N = 120). Essential features of the approach include a preference assessment for identifying multiple individualized rewards, increasing reinforcement rates during imaging by pairing tasks with chosen rewards and presenting a visual 'road map' listing tasks, rewards and current progress.

Results

Our results showing a higher percentage of fMRI task completion by healthy children provides proof of concept data for the recommended tactics. Additional support was provided by results showing our approach generalized to several additional fMRI and event-related potential investigations and clinical populations.

Discussion

We proposed that some forms of task noncompliance may emerge from less than optimal reward protocols. While our findings may not directly support the effectiveness of the multiple reward compliance protocol, increased attention to how rewards are selected and delivered may aid cooperation with completing fMRI tasks

Conclusion

The proposed approach contributes to the pediatric neuroimaging literature by providing a useful way to conceptualize and measure task noncompliance and by providing simple cost effective tactics for improving the effectiveness of common reward-based protocols.     

MRSA screening in the vascular day-case population

INTRODUCTION

The UK Government has prioritised methicillin-resistant Staphylococcus aureus (MRSA) screening and new operational guidance has instructed that all day-case surgical patients should be screened from April 2009. We sought to identify the number of MRSA-positive patients in the vascular day-case population over a 1-year period and to profile this cohort in terms of risk-factors for MRSA. We also sought to identify whether the new guidance from the Department of Health (DH) had resulted in increased screening rates.

PATIENTS AND METHODS

Electronic records and laboratory culture results were prospectively consulted to identify whether patients had been screened and if MRSA had been isolated. Consideration was given to whether any patients had a delayed discharge or subsequent admission with an MRSA-related complication.

RESULTS

Six patients (2.1%) screened MRSA-positive (DH estimate 7%); five were previously known to be MRSA-positive, therefore only 0.36% patients were newly-identified as MRSA-positive. The proportion of patients screened increased from 35% to 72.5% after April 2009, in accordance with DH guidance. Successful decolonisation was proved in two patients (33.3%).

CONCLUSIONS

There is dispute with several of the key assumptions behind the DH’s impact assessment justifying an expanded MRSA-screening policy. It is not cost-effective to screen all vascular day-case admissions. We recommend selective screening for patients previously identified as MRSA-positive, or considered high risk.
