Background: Central nervous system (CNS) lymphoma is a rare brain neoplasm. Its incidence has increased these years, so it should be considered in the differential diagnosis for mass lesions in the CNS. The aim of the study was to describe the radiological and clinical features of patients with CNS lymphoma. Methods: The study was a retrospective study. All patients histopathologically confirmed to have CNS lymphoma from November 2008 to December 2013 in Siloam Hospital Lippo Village were included in the study. Medical records and patients’ MRI results were retrieved to be analyzed. Results: 32 patients were histopathologically diagnosed to have CNS lymphoma. The patients, mean age was 54 ± 15.01 years with slight male predominance. No patient was immuno compromised (CD4 > 500 cells/µL and leukocyte 5,000-11,000 cells/µL). The median interval between the onset of the initial symptoms and diagnosis is 7 weeks. The most common presenting symptoms were headache, mental changes, and neurological deficits related to the location of lesion. MR images show that most lesions were enhanced with contrast, iso-hypointense in T1 weighted imaging (T1WI), iso- to hypointense with perifocal edema in T2 weighted imaging (T2WI), hyperintense in diffusion weighted imaging (DWI), with the most common location was white matter of cerebral hemisphere on one or more lobes and periventricular area, and the tumor could be single or multiple (24%) without clear edges. Conclusion: Short course of neurological worsening (within weeks) should lead a suspicion toward lymphoma. The characteristics of MR images are markedly enhanced by contrast, iso- to hypointense on T1WI and T2WI, and hyperintense in DWI, involving white matter of cerebral hemisphere and periventricular area.

Myocarditis is an inflammatory disease of myocard with varied onset and clinical presentation which lead to diagnosis difficulties. These difficulties often cause incoming patients with acute condition are not diagnosed as acute myocarditis that subsequently may lead to improper therapy. This circumstance will probably cause more severe myocardial injury and even sudden death. On another circumstance, patients may also come late in conditions of dilated cardiomyopathy (DCM) or aritmogenik cardiomyopathy (ARVD) due to complexities of myocarditis early detection. Therefore, myocarditis diagnosis is extremely important. This case shows how CMR is important and highly accurate in diagnosing myocarditis through a case whereby a boy had complaints of chest pain and his CMR examination showed normal cardiac morphology with normal function of right and left ventricular, but with myocardial edema and tissue fibrosis, which confirmed the diagnosis of myocarditis according to the Lake Louise Consensus criteria. CMR is an important and high accuracy non-invasive diagnostic tool in myocarditis diagnosis.

Background: Cervical cancer is the second most common cancer among Indonesian women. Information concerning survival probability is very important for the patient and institution. Our last data about cervical cancer survival was studied for more than 10 years ago. This study aimed to know the latest cervical cancer survival and its prognostic factors.Methods: This is a retrospective cohort study which enrolled cervical cancer patients treated at Cipto Mangunkusumo Hospital in 2005-2006. Subjects were followed-up for minimum of 5 years. Kaplan-Meier and Cox regression analysis was used to determine the survival probability and to assess prognostic factors. Results: A total of 447 patients who met the study criteria were selected. Stage III was the largest proportion on the study (41.6%). Most of the histopathology type was squamous cell carcinoma (71.6%). This study revealed that median survival was 63 months with the overall 5-years survival probability to be 52%. Tumor size did not influence overall survival rate. Stage III and IV had lower survival probability (HR 3.27 and 6.44). Poor differentiation and uncompleted therapy also had lower survival probability (HR 2.26 and 2.22). Histopathology of others (neuroendocrine) had lower survival probability (HR 2.85). However, it was not statistically significant on multivariate analysis. Conclusion: Median survival time for cervical cancer patients at Cipto Mangunkusumo Hospital was 63 months. There were improvement in the survival rate comparing from the study in 1997. In this study, the independent prognostic factors for survival were tumor staging, tumor differentiation, and completion of therapy.

Background: Mesenchymal stem cell (MSC) has been reported to have immunomodulator capacity against autoimmune diseases and to prevent allogenic tissue rejection. Many studies revealed that MSC’s inhibit T cell proliferation and induce immunosuppressive condition through the production of prostaglandins, and interleukin-10. In addition, MSC was reported to reduce circulating autoantibody in autoimmune patients following MSC transfusion. So far, there has been no report stating the presence of Fc receptors (receptors for immunoglobulin) on MSCs. The aim of this study was to reveal the expression of FcγRs in lipoaspirate-derived MSCs by measuring transcription of FcγR mRNA and whether the expression can be modulated. Methods: Lipoaspirate-derived MSCs were cultured in suitable medium and confirmed to be MSCs according to the criteria published by International Society for Cellular Therapy. Total mRNA of MSCs was isolated, and detection of human FcγRI, FcγRIIA and FcγRIIB mRNA was performed. Further, modulation of the expression was tested using heat aggregated gamma globulin (HAGG) and interferon (IFN)γ. Results: FcγRs mRNA was detected in the first passage of MSCs. However, the expression was no longer present after more than 4 passages. Further, increased level of FcγRI and FcγRIIA mRNA expression was detected with the addition of IFNγ in the culture. This preliminary finding opens a new insight for the understanding of interaction between MSCs and immunoglobulin G through FcγRs. Conclusion: Lipoaspirate-derived MSCs express FcγRs, and the expression is modulated by IFNγ.

Background: Tumor tissue usually became hypoxic due to disruption of oxygen supply. Adaptation response to hypoxia is mediated by transcription factor, hypoxia- inducible factor-1α (HIF-1α). HIF-1α signaling is known to increase the expression of pro-apoptotic protein cytochrome-c, and anti- apoptotic survivin. In this study we wanted to analyze the role of HIF-1α on breast cancer cells survival through pro-apoptosis cytohrome-c and anti-apoptosis survivin regulation. Methods: Breast cancer cell lines T47D were induced by CoCl 2 then harvested to analyze the expression of HIF-1α, protein cytochrome-c, mRNA survivin and cell viabilities Results: HIF-1α induction by CoCl2 causes the increase of protein and mRNA of HIF-1α, cytochrome-c protein, and survivin mRNA, but does not cause the changes in cell viability. Conclusion: HIF-1α induction have no effects on breast cancer cell line T47D viabilities due to the balance regulation between pro-apoptosis expression cytochrome-c and anti-apoptosis survivin.

Japan has long operated a government-based health insurance system covering the entire population, and has been focusing on strategies for balancing viable national health care services with the need to minimize national health care expenditure. Hemodialysis (HD) is a representative form of medical treatment that is expected to expand in Indonesia in the near future, and which will require sustained financial support from the national health insurance system. In this report, consecutive to our previous one, we describe how the Japanese government has attempted to minimize medical expenditure in the past, focusing especially on HD.

Background: Alloantibodies against human platelet alloantigens (HPAs) are responsible for the development of platelet transfusion refractoriness (PTR) in patients receiving random platelets and bleeding disorder in babies with fetal neonatal alloimmune thrombocytopenia (FNAIT). Recently, our results based on the analysis of the allelic distribution of HPAs indicated that immunization may occur among Malay. In this study, we sought to analyze the frequencies of platelet reactive alloantibodies responsible for FNAIT and PTR in Malaysia.Methods: Sera from suspected FNAIT (n = 295) and PTR (n = 74) were collected in five years period (2008-2013) and tested for the presence of platelet reactive antibodies by the use of antigen capture assay. Results: In 5/74 (5.41%) platelet specific antibodies against HPA-2b (n = 1), HPA-5a (n = 1), HPA-5b (n = 1), HPA-15b (n = 2) could be identified in our PTR cohort. In FNAIT cohort, platelet specific alloantibodies could be detected in 18 sera (6.10%) consisting anti-HPA-1a (n = 1), anti-HPA-3a (n = 3), anti-HPA-5a (n = 6), anti-HPA-5b (n = 6), anti-HPA-15a (n = 1), and anti-HPA-15b (n = 1). Conclusion: Our study indicates that anti-HPA-3, -HPA-5 and -HPA-15 antibodies seems to be the most platelet specific antibodies involved in FNAIT and PTR cases in Malaysian population. Since similar HPA allelic distribution among Malaysian and Indonesian populations have been observed, immunization against these three HPA systems are expected to be the most potential risk of alloimmune mediated platelet disorders in Indonesia.

Background: Liver is sensitive against hypoxia and hypoxia will stabilize HIF-1α. At the same time, hypoxia will produce reactive oxygen species (ROS) which can be scavenged by Cygb. The purpose of our study is to know, if normobaric hypoxia can induce Cygb expression and its association with HIF-1α stabilization. Methods: This is an experimental study using 28 male Sprague-Dawley rats, 150-200 g weight. Rats are divided into 7 groups: control group and treatment groups that are kept in hypoxic chamber (10% O2: 90% N2) for 6 hours, 1, 2, 3, 7 and 14 days. All rats are euthanized after treatment and liver tissue are isolated, homogenized and analyzed for oxidative stress parameter, expression of Cygb and HIF-1α. Results: Expression of Cygb mRNA and protein was increased on the day-1 after treatment and reach the maximum expression on the day-2 of hypoxia treatment. But, the expression was decreased after the day-3 and slightly increased at the day-14 of hypoxia. The correlation between expression of Cygb and oxidative stress parameter was strongly correlated. Cygb mRNA, as well as protein, showed the same kinetic as the HIF-1, all increased about day-1 and day-2. Conclusion: Systemic chronic hypoxia and/or oxidative stress up-regulated HIF-1α mRNA which is correlated with the Cygb mRNA and protein expression. Cygb mRNA as well as Cygb protein showed the same kinetic as the HIF-1, all increased about day-1 and day-2 suggesting that Cygb could be under the regulation of HIF-1, but could be controlled also by other factor than HIF-1.
