Abstract

Background: Nasopharyngeal carcinoma (NPC) is a multifactorial genetic disease, characteristically endemic and shows considerable differences in its geographical distribution. Besides infection with EBV, genetic factors such as polymorphisms of TCR-β gene contribute to the incidence of NPC. This study investigates the association of TCR-β gene polymorphisms with individual susceptibility to develop NPC in Indonesian ethnic groups. Methods: The study was carried out by the PCR-RFLP method using Bgl II restriction enzyme to digest TCR-β gene. The PCR-RFLP analysis of TCR-β gene was used to determine allotypes of TCR-β gene in NPC patients and control among ethnic Chinese and indigenous groups in the population of Indonesia. Results: The results indicate that the distribution of TCR-β gene allotypes between NPC patients and controls are not signifi cantly different (p > 0.05); however, the frequency of A allele tends to increase in NPC patients. The distribution of TCR-β gene allotypes between Chinese ethnic group was not signifi cantly different from indigenous groups (p > 0.05). Conclusion: The distribution of TCR-β gene allele between NPC group and control groups showed no difference. The distribution of TCR-β gene between ethnic Chinese and indigenous groups showed no difference. Polymorphisms of TCR-βgene are not associated with NPC and ethnic groups in Indonesian population.

Abstract

Background: The quantitative assays are important tests in the management of patients with HIV-1/AIDS. The important step in developing the assay is the availability of the standard HIV-1 RNA. For this purpose, we optimized in vitro HIV-1 RNA transcription to produce the standard HIV-1 RNA. Methods: The HIV-1 DNA was amplified from pNL43 by PCR using a primer pair that was specific for conserved region of HIV-1 Gag gene. The PCR product was further cloned into pBluescript II KS. The recombinant plasmid was restricted with EcoRI enzyme. Then, the linearized plasmid was used as template for RNA transcription. RT-PCR and PCR were performed simultaneously for confirmation of synthesized RNA fragment. Results: A 115 bp DNA of HIV-1 Gag gene has been cloned into pBluescript II SK with the exact true orientation. The reaction of the RNA transcription was also successfully performed. The RNA transcripts have been confirmed and showed the accuracy of the transcripts. Conclusion: We successfuly constructed the recombinant plasmid containing a conserved region of HIV-1 Gag gene, and the HIV-1 RNA has been transcribed in vitro as well.

Abstract

Background: Over the last 10 years, we have investigated thalassemia patients in Jakarta to obtain a comprehensive picture of iron overload, oxidative stress, and cell damage. Methods: In blood samples from 15 transfusion-dependent patients (group T), 5 non-transfused patients (group N) and 10 controls (group C), plasma lipids and lipoproteins, lipid-soluble vitamin E, malondialdehyde (MDA) and thiol status were measured. Isolated eryhtrocyte membranes were investigated with electron paramagnetic resonance (EPR) spectroscopy using doxyl-stearic acid and maleimido-proxyl spin lables. Data were analyzed statistically with ANOVA. Results: Plasma triglycerides were higher and cholesterol levels were lower in thalassemic patients compared to controls. Vitamin E, group C: 21.8 vs T: 6.2 μmol/L) and reactive thiols (C: 144 vs. T: 61 μmol/L) were considerably lower in transfused patients, who exert clear signs of oxidative stress (MDA, C: 1.96 vs T: 9.2 μmol/L) and of tissue cell damage, i.e., high transaminases plasma levels. Non-transfused thalassemia patients have slight signs of oxidative stress, but no signifi cant indication of cell damage. Erythrocyte membrane parameters from EPR spectroscopy differ considerably between all groups. In transfusion-dependent patients the structure of the erythrocyte membrane and the gradients of polarity and fl uidity are destroyed in lipid domains; binding capacity of protein thiols in the membrane is lower and immobilized. Conclusion: In tranfusion-dependent thalassemic patients, plasma lipid pattern and oxidative stress are associated with structural damage of isolated erythrocyte membranes as measured by EPR spectroscopy with lipid and protein-thiol spin labels.

Abstract

Background: The present study was aimed to explore the effects of ritonavir and primaquine combination given as a singledose or repeated-dose compared to ritonavir alone on ritonavir plasma concentration in the rats. Methods: In single-dose study, 30 male Spraque Dawley rats were randomly allocated to receive ritonavir 20 mg/kg BW or ritonavir 20 mg/kg BW + primaquine 1.2 mg/kg BW or ritonavir 20 mg/kg BW + ketokonazole 10 mg/kg BW. Ketokonazole was used as positive control of ritonavir metabolism inhibitor. In the repeated-dose study, thirty Spraque Dawley male rats were randomly allocated to receive ritonavir 20 mg/kg BW/day or ritonavir 20 mg/kg BW/day + primaquine 1.2 mg/kg BW/day or ritonavir 20 mg/kg BW/day + rifampicin 100 mg/kg BW/day. Rifampicin was used as a positive control of ritonavir metabolism inducer. Results: In the single-dose study, ketokonazole increased the area under the plasma concentration (AUC) of ritonavir (↑114.8%, p< 0.05), while primaquine tended to decrease the AUC of ritonavir (↓32.6%, p> 0.05). Repeated-dose study showed that rifampicin decreases the AUC of ritonavir (↓42.8%, p< 0.001), and primaquine decreased the AUC of ritonavir plasma concentration (↓46.6%, p< 0.001). Conclusion: Concomitant administration of primaquine and ritonavir decreases the AUC of ritonavir. This effect may result in the insufficient concentration of ritonavir as anti-HIV, which may lead to treatment failure with ritonavir. (Med J Indones 2011; 20:190-4)

Abstract

In the midst of on-going non-illicit practice of silicone or paraffin injection to enlarge penis, the author reported 3 cases of surgical treatment to resurface the body of the penis after excision of the destructed penile skin using full thickness skin graft. The skin excision was performed technically through penile body degloving procedure. Full thickness skin graft was then applied as a single sheet donor tissue to cover the denuded penile body spirally. The full thickness graft, which is relatively easy to be performed, is no doubt much thinner than a skin flap, while it also bears a smaller degree of secondary contraction than split skin graft. The color of the skin is considerably matched as it comes from the groin, which is a nearby area of penis. The size and skin sensitization of the penis looks to be natural. The only disadvantage is the common possibility of either spiral or circular junctional scar in between graft edges and between the graft and the penile mucosa and skin to develop hypertrophic scar. However, this possible scar problem applies also to any other surgical scar with any donor tissue. Fortunately, the 3 cases posed no scar problem and normal appearance. All the patients have also regained their normal sexual function. (Med J Indones 2011; 20:222-5)

Abstract

IgD κ myeloma is a rare plasma cell neoplasm case and has never been reported before in Indonesia. In normal condition, IgD level in blood is very low, therefore increase of IgD level in myeloma could be missed by serum protein electrophoresis.A case of a 59 years old female with severe bone pain is reported. In radiology evaluation, there were thoracal compression fracture and thoracal foramen narrowing. For this patient, the myeloma diagnosis was based on WHO criteria, the stage IIIb was based on Durie and Salmon criteria, and bad prognosis with prognostic index stage III diagnosis was based on International Prognostic Index from International Myeloma Working Group, respectively. In serum protein electrophoresis we found a very small monoclonal spike and in immunofi xation there were monoclonal IgD κ and free light chain κ. (Med J Indones 2011; 20:217-21)

Abstract

Background: A parameter is needed in medical activities or services to determine functional capacity. This study is aimed to produce functional capacity parameter for Indonesian adult as maximum O2. Methods: This study used 123 Indonesian healthy adult subjects (58 males and 65 females) with a sedentary lifestyle, using a cross-sectional method. Results: Designed by using the followings: distance, body height, body weight, sex, age, maximum heart rate of six minute walking test and lung capacity (FEV and FVC), the study revealed a good correlation (except body weight) with maximum O2. Three new formulas were proposed, which consisted of eight, six, and five variable respectively. Test of the new formula gave result of maximum O2 that is relevant to the golden standard maximum O2 using Cosmed® C-Pex. Conclusion: The Nury formula is the appropriate predictor of maximum oxygen uptake for healthy Indonesians adult as it is designed using Indonesian subjects (Mongoloid) compared to the Cahalin's formula (Caucasian). TheÂNury formula which consists of five variables is more applicable because it does not require any measurement tools neither specific competency. (Med J Indones 2011;20:195-200)

Abstract

Background: Vaginal candidiasis (VC) is one of the most common fungal diseases. Candida albicans is the most common causative fungus and has been isolated from more than 80% of specimens obtained from women with VC. Ketoconazole is the first orally active antifungal, the dosage for VC is 200 mg twice daily for 5 days. Fluconazole is the newer oral antifungal, its dosage for VC is a single oral dose of 150 mg. Since fluconazole 150 mg is considerably expensive, a single dose of 100 mg ketoconazole and 40 mg fluconazole in combination has been tested for the treatment of VC. The results showed that from 11 women with confirmed VC, 1-2 weeks after drug administration, the mycological culture was negative in 8 women, positive in 1 woman, and 2 woman lost to follow-up. This promising result led to the present study with the objective to confirm the efficacy and safety of the above combination in a formal clinical trial. Methods: A total of 165 female patients, aged 18 years or older, with the diagnosis of VC from clinical symptoms (pruritus or burning or excessive discharge) and positive microscopic smear (pseudohyphae and/or yeast cells) were randomized to receive a single dose of either keto-fluco combination (n = 85) or fluconazole (n = 80), and returnedfor follow-up visit on day 8. Results: Among these patients, 39 patients had negative baseline culture, leaving 126 patients eligible for efficacy evaluation. The mycological eradication in the keto-fluco group was 74.5% (41 patients from a total of 55 patients with available mycological culture), while that in the fluconazole group was 70.2% (40 patients from 57 patients with available culture) and this difference was not significant. The clinical favorable response (clinical cure and clinical improvement) in the keto-fluco arm (n = 60) was 98.3%, while that in the fluconazole group (n = 66) was 100%. Adverse events were found in 5 patients, 3 patients in the keto-fluco group (3/85 = 3.5%) and 2 patients in the fluconazole group (2/80 = 2.5%). Conclusion: The present study showed that the efficacy and safety of ketoconazole 100 mg and fluconazole 40 mg combination was not inferior compared to fluconazole 150 mg in single doses for the treatment of vaginal candidiasis.

Abstract

Background: WHO classified the number of leprosy cases in Indonesia as number three in the world after India and Brazil. The number of new leprosy patients tends to increase since there is a possibility that seropositive leprosy is turning into manifest leprosy. The aim of this study was to analyze the influence of zinc supplementation on interleukin-2 (IL-2) level of seropositive contact of leprosy patients with marginal zinc deficiency. Methods: Twenty two subjects aged 20-40 years were recruited for this study. The zinc-supplemented group received 40 mg elemental Zn/d orally for 3 months. Seropositive leprosy was determined by examining IgM anti Phenolic Glycolipid-1 level and concentration of IL-2 in lymphocyte cell culture supernatant fluid were measured by Elisa method. Results: The IL-2 concentration in the subject in the zinc group was relatively not changed (p= 0.721), whereas that in placebo group tended to be significantly lower (p= 0.025) at the end of the study. Conclusion: There was a significant change of IL-2 level between both groups (p= 0.037). (Med J Indones 2011;20:201-4)

Abstract

Background: Low Back Pain (LBP) is the most frequently reported musculoskeletal disorder in workers. This study was aimed to develop risk prediction model of low back pain that can be used to prevent the recurring low back pain attack. Methods: The study was case-control design based on the industrial community by using ergonomical approach. Total samples were 91 workers for cases and 91 workers for controls. Workers suffering for low back pain in the last 6 months served as cases, and those from the same age group and receiving the same amount of exposure without any symptoms of low back pain served as controls. Risk factors include socio-demographic factors, socio-ocupational factors, physical working environmental factors, non-physical environmental factors, and biomechanics factors. Receiver Operating Characreistics (ROC) was used to describe relationship between true positive value (in vertical axis) and false positive value (in horizontal axis) in order to discover a risk predictive value of LBP. Results: The determinant risk factors for low back pain (LBP) were bending work postures, waist rotation movement, manual lifting, unnatural work postures, those who had worked for more than 18 years, and irregular sport activities. By using ROC with 91.20% senstivity and 87.90% spesifi city, the calculated prediction value was 0.35. This is the cut-off point to discriminate workers with and without LBP. The risk predictors value of work-induced LBP calculated by linear equation of logistic regression varied between 0-11.25. Conclusion: The prediction model of work-induced LBP can be used for early detection of LBP to reduce the risk and prevent the recurrence of LBP. (Med J Indones. 2011; 20:212-6)
