Abstract

Stigma towards leprosy is usually generated not only from the unpleasant appearance of the patients, but also people’s false perceptions and insufficient knowledge concerning leprosy. The purpose of this study was to analyze the relationship between knowledge and stigmarelated attitudes, affect and behavioral intentions towards leprosy patients among medical students. A cross-sectional study was performed by distributing questionnaires consecutively to 77 medical students in a Competency-Based Curriculum (CBC) 2005 of Faculty of Medicine University of Indonesia in April 2009. We assigned their gender, age, knowledge, along with sources and score of their knowledge. Then, we analyzed the relationship between knowledge and attitudes, affect and behavioral intentions towards leprosy patients. The questionnaire assessing knowledge was made by authors and experts after validity assessment (minimum alpha reliability = 0.514 and reliability coefficient = 0.845), while the questionnaire for stigmarelated attitudes, affect and behavioral intentions was adapted and translated to Bahasa from Attribution Questionnaire-Short Form (AQ-SF) after validity checking with Cronbach’s alpha; the minimum was 0.514 and the reliability coefficient 0.897. The subject consisted of 36 male and 41 female students whose age was varied from 18 to 23 years old with the most common source of knowledge concerning leprosy was school. Correlation analysis showed weak negative correlation (r = -0.267 and p = 0.019) between knowledge and AQ-SF score. The higher the knowledge, the lower the AQ-SF score, meant that stigma-related attitudes, affect, and behavioral intentions were better.Keywords: knowledge, leprosy, medical student, stigma

Abstract

Asymptomatic urinary tract infections (UTIs) in pregnant women who are not treated appear more likely to develop serious complications on occassional life threatening and risk to deliver more low birth weight neonates. Thus, it is necessary to test whether the infection is really present or not. Urine culture as the gold standard examination still has limitations. This report was made to examine nitrite as a component of urinalysis to be an alternative test for asymptomatic UTIs. A search was conducted on PubMed,® Proquest,® Cochcrane® and Embase.® After screening titles and abstracts by inclusion and exclusion criteria, 16 original articles were found, but only 4 articles were used by author. All four articles showed high negative predictive value (0.82-0.96) and three of them showed good post-test probability (<0.09) when the test result was negative for asymptomatic UTIs. On the other hand, the positive predictive value (0.5-0.69) was poor. Based on the results, nitrite is not strong enough as a sole test for diagnosing asymptomatic UTIs. But, we found that nitrite is good enough to confidently rule out the asymptomatic UTIs in pregnant woman.Keywords: asymptomatic UTI, nitrite, diagnosis, pregnant woman.

Abstract

Heat shock protein has been known to have important role in insulin resistance. Insulin resistance is one of the major cause of diabetes mellitus. According to WHO, Diabetes Mellitus has the 4th highest peak of mortality rate. Insulin resistance influenced by some factors, one of them is the presence of free fatty acid. Free fatty acid influenced the phosphorilation of insulin receptor mediated by IkK- beta and JNK. Heat Shock Protein is important in preventing the phosphorilation of insulin receptor. The phosphorilation cause  inactivation of the insulin receptor. Hsp also play an important role in the defense mechanism of islet cell against free radicals, and decreasing lipid oxidation, which correlated with the pathogenesis of insulin resistance. Insulin resistance can be ameliorated by using some modalities which resulted in increasing the expression of Hsp.Keywords: insulin resistance, heat shock protein, modalities

Abstract

Liver cirrhosis often causes varices in the gastric or esophagus. It would be dangerous if there is bleeding from ruptured varices. Variceal bleeding can be happened due to portal hypertension resulted by increased resistance to portal flow and increased portal blood inflow into the portal vein. Prevention of recurrent bleeding from ruptured varices becomes a challenge for every doctor since after the first bleeding, the possibility of recurrent bleeding raises very high. Therefore, it is important to perform a secondary prevention, such as pharmacological therapy, endoscopy and other therapies, to prevent recurrent bleeding. In this review, we described risk factors, pathophysiology, therapy and management of recurrent bleeding in patients with liver cirrhosis.

Abstract

Allergic diseases, especially allergic rhinitis were estimated to continue rising. Hereditary factors are importantfactors that could cause allergic rhinitis. Prebiotics is recently believed to play a role in the prevention of allergic rhinitis. This report was made to reveal whether probiotics can be used for prevention of allergic rhinitis. Searching articles were done on PubMed, Embase, and Cochrane. After searching, selecting and reading six articles obtained, only three articles that were suitable with our PICo. All three articles show that probiotics, especially Lactobacillus GG strain were not significantly having protective effect on allergic rhinitis, although all three studies have good validity. According to our appraisal, probiotics have not been proven enough and still could not be used to prevent allergic rhinitis in children.

Abstract

Background Anemia in children and adolescents affects growthand development. It is a preventable disease, but unfortunately isoften ignored until the symptoms occur. There have been limitedreports on the prevalence of anemia in children and adolescentsin Indonesia, especially from rural areas.Objective To describe the prevalence of anemia in children andadolescents in district ofMalinau, a rural area in East KalimantanProvince.Methods This cross-sectional study was done in June 20 10 usinglaboratory records between July 2009 to January 20 10. Laboratoryrecords of patients aged between 6 months and 18 years whichinvestigated were complete blood count (CBC) from ambulatory,inpatient, and emergency care ofMalinau Public Hospital in EastKalimantan. Mentzer and England & Fraser indices were used todifferentiate iron deficiency anemia (IDA) and thalassemia amongmicrocytic hypochromic anemic patients.Results This study involved 709 laboratory records. Prevalenceof anemia was 53 .9% (95% CI 50.2% to 57 .5%) . The prevalenceof IDA among age groups were as follows: 29.4% (95% CI 24.3to 34.5%) in 6- 59 months group, 16% (95% CI 11 to 21 %) in5- 11.9 years, and 15.2% (95% CI 10.2 to 20.2%) in 12- 18 years.Children aged 6- 59 months tended to have more anemia th anthose aged 5- 11.9 years (OR 2. 184, 95% CI 1.398 to 3.413) oraged 12- 18 years (OR 2.3 19, 95% CI 1.464 to 3.674).Conclusion T he prevalence of an emia in children andadolescents of the Malinau Regency is 53 .9% (95% CI 50.2 to57.5%), quite similar to that of other developing countries .
