Allergic rhinitis (AR) is a globally increasing health problem affecting the quality of life. Specific immunotherapy is an available causal treatment changing the basic allergic mechanisms of the disease. Over one hundred years, subcutaneous immunotherapy (SCIT) was developed and proved its efficacy but many adverse effects were recorded including anaphylaxis. In 1986, sublingual immunotherapy (SLIT) was introduced as an alternative solution to solve this problem. Our study aims to discuss SLIT from the points of efficacy, safety, adherence and guidelines developed. A literature search was conducted in Medline/PubMed and the Cochrane Library in January 2013 using the keywords "allergic rhinitis, sublingual immunotherapy, efficacy, safety, compliance, adherence, guidelines." All types of publications were included. We augmented our study by searching the reference lists of identified reviews. SLIT has been established in many guidelines as an evidence-based effective treatment in AR with safer profile than SCIT. The meta-analyses confirmed its efficacy and showed a significant reduction in both symptoms and medication scores. The most common recorded adverse effects were minor local effects in the mouth, gastrointestinal reactions with few cases of anaphylaxis and no fatality. Adherence is more favorable for SLIT mainly because it is safe, noninvasive and easily taken at home. We support the call to conduct large multi-centric studies to gain more statistical power and overcome the problem of heterogeneity observed in the meta-analyses.

Background: Magnetic resonance imaging (MRI) is a noninvasive method for determining brain morphology and volumetry. Hippocampal volume changes are observed in conjunction with several diseases. This study aimed to determine the normalised volume of the hippocampus in normal Malay children and adolescents. Methods: This was a cross-sectional study performed from January 2009 to June 2010. Brain and temporal lobe MRI was performed for 81 healthy normal Malay individuals aged 7–18 years. Manual volumetry was performed. The hippocampal volumes were normalised with the total intracranial volume. Results: The original right, left, and total hippocampal volumes (mean and standard deviation) were 3.05 (0.48) cm3, 2.89 (0.44) cm3, and 5.94 (0.90) cm3, respectively. Normalised hippocampal volumes for the right, left, and total volume were 3.05 (0.41) cm3, 2.89 (0.41) cm3, and 5.94 (0.79) cm3, respectively. Pearson’s correlation coefficient for the right and left hippocampal volumes with intracranial volume were 0.514 and 0.413, respectively (P < 0.001). Both the original and normalised hippocampal volumes of the right hippocampus were significantly larger than those of the left (P < 0.001). Conclusion: This is a data set for the local Malay paediatric population. There was no significant difference between the actual and normalised values of hippocampal volume in our study.

Malnutrition can be associated as one of the factors which affect health status. The term is used to describe imbalance of nutrients either over- or under-nourished, resulting in measurable adverse effects on body composition, function and clinical outcome. The National Health And Morbidity Survey (NHMS) 2011 assessed 4304 individuals aged 10-17 years old through a household survey of Malaysian population. Thinness and obesity are the malnutrition indicators based on Centre for Disease Control (CDC) 2000 classification as recommended by WHO (2007). The findings of the survey showed that the national prevalence of thinness (BMI for age <-2SD), was 9.7% (95% Confidence Interval: 8.4-11.2). The state of Sabah/Labuan had the highest thinness of prevalence, 17.0% (11.1-25.2) and lowest in Penang at 5.3% (2.7-10.0). The prevalence of thinness was higher in urban areas than in rural areas at 10.3% (8.5-12.3). Meanwhile; national prevalence of obesity (BMI for age ≥+2SD) was only 5.7% (4.9-6.7). The state of Perak had the highest obesity prevalence 10.0% (6.2-15.8) and lowest in Sabah/Labuan at 2.4% (1.4-4.1). The obesity prevalence was higher among adolescents in urban areas at 6.3% (5.2-7.6) than in rural areas. Thinness as a form of malnutrition is more prevalent than obesity. Even though the prevalence of obesity is low, the impact affects not only the adolescents, but also the family, the society and the nation in the future. The increasing prevalence of obesity will have significant public health implication related to non-communicable diseases.

Background: Atrial tachycardia poses challenges in patient management due to the associated risks of stroke and systemic embolism. While anticoagulation is recommended in atrial fibrillation (AF), its role in atrial tachycardia remains less defined. This prospective study aimed to evaluate the efficacy and safety of apixaban, a direct oral anticoagulant, in individuals diagnosed with left-sided atrial tachycardias. Methods: Patients diagnosed with left-sided atrial tachycardia (n = 439) were observed over 3 years. Baseline characteristics, medication regimens, and clinical outcomes were assessed. Apixaban-treated individuals (n = 213) received standard or reduced dosages, while the control group (n = 226) received standard care. Primary outcomes included stroke, systemic embolism, bleeding, and mortality rates. Results: Baseline characteristics were comparable between groups. The apixaban cohort showed a lower incidence of stroke (7.0% vs. 9.3%, p = 0.027) and decreased all-cause mortality (11.7% vs. 12.8%, p = 0.012) compared to controls.No significant differences were found in major bleeding or systemic embolization between groups. Conclusion Apixaban demonstrated a potential benefit in reducing stroke and mortality rates in patients with leftsided atrial tachycardia. While requiring further validation, these findings suggest a potential role for apixaban in anticoagulation strategies for atrial tachycardia management.

INTRODUCTIONRetinopathy of prematurity (ROP) can lead to severe visual impairment. This study was conducted to determine the levels of biochemical mediators (i. e. vascular endothelial growth f actor [ VEGF] and insulin- like growth factor-1 [IGF-1]) in the blood of premature infants with proliferative ROP.

METHODSBlood samples from 71 preterm infants born at or before 32 weeks of gestation were obtained 6-8 weeks after birth. These infants were classified into two groups according to their eye examination results. The control group consisted of 41 infants who had no evidence of ROP, and the study group consisted of 30 infants with proliferative ROP at stage III or higher. Blood VEGF and IGF-1 levels were measured using enzyme-linked immunosorbent assay.

RESULTSThe mean gestational ages of the infants at birth were 28.4 ± 1.6 and 28.8 ± 1.6 weeks in the study and control groups, respectively (p = 0.259). The mean postmenstrual age of the infants at the time of blood sampling was 34.9 ± 1.2 weeks in the study group and 34.6 ± 1.3 weeks in the control group (p = 0.339). The mean blood IGF-1 (18.48 ± 11.79 µg/L and 16.75 ± 13.74 µg/L in the study and control groups, respectively; p = 0.580) and VEGF (267.35 ± 103.43 pg/mL and 237.52 ± 130.92 pg/mL in the study and control groups, respectively; p = 0.305) levels of the infants were not significantly different between the two groups.

CONCLUSIONAt 6-8 weeks after birth, blood IGF-1 and VEGF levels were not found to be significantly different between premature infants with proliferative ROP and those without.

Objective: To detect the presence of specific CTX-M class of extended spectyum β-lactamases (ESBLs) in a collection of cephalosporin-resistant Enterobacteriaceae isolates from Bahrain. Methods: A subset of 80 cephalosporin-resistant Enterobacteriaceae collected from Salmaniya Medical Complex, Bahrain, were characterized further for the presence of specific genogroups of CTX-M β-lactamases by multiplex- and monoplex- PCRs. The primers used for the multiplex and monoplex PCRs were of genogroups- 1, 2, 8, 9 and 25. Sequencing of the representative isolates was performed to find the circulating CTX-M-types. Results: A total of 93.8% (75/80) isolates showed the amplicons corresponding to any of the genogroups (1, 2, 8, 9, 25) and the remaining 6.2% isolates turned out negative in multiplex PCR. Some of the isolates demonstrated multiple bands corresponding to the sizes of different genogroups. Further confirmation with respective monoplex PCR on these 75 isolates demonstrated that 93.3% (70/75) harbored CTX-M genogroup-1 and 6.7% (5/75) harbored genogroup-9. We did not find the presence of genogroups 2, 8, and 25 in these isolates by monoplex PCR. Sequencing results of genogroup-1 isolates demonstrated the presence of CTX-M-15-like ESBL, however, discrepant results were noticed in genogroup-9 isolates, sequencing showed them as CTX-M-55-like ESBL. Conclusions: This is the first report from Bahrain characterizing the CTX-M genogroups of ESBLs and reporting the emergence of bla
