An appraisal of a 17-year primary thyroid stimulating hormone (TSH) screening programme for the detection of congenital hypothyroidism was carried out to establish the reference interval of cord blood TSH in unaffected infants; the mean cord blood TSH concentration of affected infants and the incidence of congenital hypothyroidism in the Najran province of Saudi Arabia. Our findings show a reference interval of cord blood TSH of 2.0–16.8 mU/l in unaffected infants; a mean cord blood TSH concentration of 399 mU/l in affected infants; a false positive rate for the diagnosis of at-risk infants of 1.02% and a congenital hypothyroidism incidence rate of 34/100 000 (1 : 2931) live births. These findings suggest that there is a need to reset the cord blood TSH concentration for the detection of at-risk infants. We suggest that the detection level of cord blood TSH for the recognition of at-risk infants can be set at 90 mU/l rather than the recommended level of 30 mU/l. This should reduce the false positive rate for detection of infants at risk of congenital hypothyroidism.

Validation of a Clinical Score for the Diagnosis of Late Onset Neonatal Septicemia in Babies Weighing 1000-2500 g
There is paucity of data about the predictive values and likelihood ratios of clinical signs of late onset nosocomial sepsis in neonates. A clinical score comprising of seven items had been derived from analysis of individual signs and had been published by this group in the Journal of Tropical Pediatrics in 2003. The current study was done to validate the score in a fresh validation cohort, to evaluate the score at 0 and 24 h after onset of clinical signs of sepsis and to evaluate the sepsis screen in combination with the clinical score. The seven clinical signs in the clinical score included grunting, abdominal distension, increased prefeed aspirates, tachycardia, hyperthermia, chest retractions and lethargy. A total of 220 episodes of sepsis among 208 babies were evaluated. The clinical score was calculated at 0 h and 24 h. A sepsis screen (micro erythrocyte sedimentation rate, C reactive protein, absolute neutrophil count and immature/total neutrophil ratio) and blood culture were performed in all subjects at enrollment. Sepsis screen was considered ‘positive’ if any two parameters were positive. The outcome of interest was ‘definite sepsis’, defined as blood culture positive. The 0-h clinical score had sensitivity, specificity, PPV, NPV, LR+ and LR– of 90, 22.5, 30.3, 85.7, 1.16 and 0.44%, respectively. The 24-h score had higher specificity (60.6%) but lower sensitivity than the 0-h score. Sepsis screen per se had a sensitivity and NPV of 48.3 and 78.3% but when combined with the 0-h clinical score, the sensitivity and NPV rose to 95 and 90.6%, respectively. The ‘clinical score’ in combination with sepsis screen result can be used by clinicians to rule out sepsis.

Pattern of Malaria-specific T-Cell Responses in a Cohort of Ugandan Children
Malaria is the leading cause of morbidity and mortality in children in Uganda. The mechanisms whereby malaria parasites are eliminated, or how they may avoid the immune response remain poorly understood. We examined malaria-specific T-cell responses in a well-characterized cohort of African children in an endemic area where malaria transmission occurs throughout the year. In studies of asymptomatic children, we found a low frequency of malaria-specific T-cell responses (15/117), and these appeared to be clustered in older children (≥4 years old). Both CD4– and CD8-mediated T-cell responses were detected against circumsporozoite surface protein (CSP) and merozoite surface protein-1 (MSP-1). The presence of these T cells did not correlate with the frequency of prior episodes of parasitemia and 5 out of the 15 responders had no documented parasitemia within 8–12 months prior to immunologic evaluation. Our data supports focusing on high-risk children in future preventive vaccination efforts to ensure the generation and maintenance of effective anti-malarial cellular immune responses.

Prevalence of Celiac Disease, Helicobacter pylori and Gastroesophageal Reflux in Patients with Refractory Iron Deficiency Anemia
Objective: The aim of this article is to determine the prevalence of celiac disease (CD), Helicobacter pylori (H. pylori) and gastroesophageal reflux (GER) in patients with resistant iron deficiency anemia (IDA). Patients: The study included 25 patients 2 years and it was statistically significant (p = 0.05*). Also patients with H. pylori had age of presentation ≤4 years in five patients (41.7%) and the remaining seven patients (81.8%) had age of presentation >4 years and it was statistically significant (p = 0.03*). Logistic regression analysis demonstrated that the risk factors for severity of anemia were age of patients and duration of anemia. On the other hand, other parameters have no significant influence on the severity of anemia. Also risk factors of short stature were age of presentation of anemia, degree of anemia and H. pylori infection. AGA had the highest sensitivity (100%) followed by antiendomysium antibody (81.8%) while the tTG antibody had the highest specificity (85.7%) for diagnosis of CD. UBT and histopathology had the highest sensitivity (100%) for diagnosis of H. pylori while rapid urease test, culture, H. pylori stool antigen and anti-H. pylori IgG antibody had the highest specificity (100%). In conclusion, refractory IDA may be due to clinically unapparent H. pylori gastritis and CD. CD is one of the most common causes of intestinal malabsorption during childhood which leads to impairment of iron absorption. Apart from offering them gluten-free diet rich in iron, early detection and treatment of IDA and prophylactic iron and folic acid supplementation will go a long way to optimize their mental and psychological functions. Eradication of H. pylori infection with concomitant iron therapy should correct the anemia.

Pain Reduction of Heel Stick in Neonates: Yakson Compared to Non-nutritive Sucking
The purpose of this study was to test the effect of Yakson (i.e. a traditional Korean touching method) and non-nutritive sucking (NNS) on reducing the pain that neonates experience when undergoing the heel stick procedure for blood testing. Ninety-nine healthy neonates were recruited and assigned into three groups: Yakson (n = 33), NNS (n = 33), and control group (n = 33). Each intervention was provided to the Yakson and NNS groups from 1 min before heel stick until the completion of the heel stick. For the Yakson group, a researcher caressed the belly of a neonate with one hand while supporting the back with the other hand. For the NNS group, a pacifier packed with sterile gauze was put in the neonate’s mouth. The oxygen saturation levels in the Yakson and NNS group neonates were maintained significantly better than in the control group neonates. There was no significant difference between the groups with regard to heart rate and neonatal infant pain, measured using the Neonatal Infant Pain Scale. Findings indicate that Yakson can be used during heel stick to help neonates maintain their oxygen saturation level following the procedure.
