Abstract

Background: Heating process with autoclave is one of limb salvage modalities that are widely used. but the results are not satisfying, due to mechanical bone fragility. However, considering this treatment modality is widely accepted in terms of financial, religion and sociocultural aspects, we conducted a on study rats treated with resection and reconstruction with autoclave heating method to assess bone healing by sequential radiology, histopathologic osteoblasts count, and bone morphogenetic protein (BMP). Methods: Thirty six Sprague-Dawley rats were divided into two groups with one group being the autoclave group and others served as control group. In both groups, the tibial diaphysis was extracted en bloc for 7 mm. All groups were kept for 8 weeks and treated under the same condition except the autoclave group, where the extracted bones were put into autoclave at 134°C for 15 minutes and refixed again with k-wire. We performed radiological examination at 5th and 8th week using Lane and Sandhu radiological score. After extraction, the tibial bones were inspected for histological pattern using Salked modified score, osteoblast quantity counting and BMP-2 values. Results: There were statistically significant diffences between control and autoclave group on radiological score at 5 th (5.12 ± 1.6 g vs 3.21 ± 2.42, p = 0.023) and 8 th week (6.06 ± 1.71 vs 4.29 ± 2.53, p = 0.040), histological score between groups (6.06 ± 1.14 vs 4.14 ± 1.99, p = 0.005), osteoblast count (p < 0.001), and BMP-2 expression, respectively. Conclusion: Autoclave recycling autograft lowered the speed of graft incorporation and BMP-2 expression. Therefore, autoclave recycling autograft as a method of limb salvage surgery must be reevaluated and not considered to be applied for treatment in bone malignancy.

Abstract

Background: Hydration status in the working environment of hot and conveniently cool may influence the health status of workers, including their hydration status. This study aimed to determine the health, nutrition and hydration status of workers in two different working environment, i.e. hot and conveniently cool environment. Methods: A cross-sectional comparative study was done on apparently healthy male subjects, age 25-45 years. Two groups of factory workers consisted of 39 subjects working in environment exposed directly to heat and the other doing administrative work in cool environment. Data on their health status (physical examination), weight, height, waist circumference, fat body composition, laboratory result, were collected. The data was presented as average value and proportion; statistical analysis with unpaired-t (Mann-Whitney test) and chi-square test was used. Results: Subjects working in a hot environment were more prone to dehydration in comparison to their counterparts, as was shown by significantly higher values of several hydration status biomarkers: hemoglobin (15.6 vs 14.8 g/dL, p = 0.017), hematocrit (46 vs 44.5%, p = 0.040), blood viscosity (23 vs 12 mEq/L, p < 0.001), and blood sodium concentration (140 vs 138 mEq/L, p < 0.001). In contrast, subjects working in a conveniently cool environment who did more administrative tasks were physically less active, had significantly lower HDL-cholesterol level (43 vs 52.1 mg/dL, p = 0.005), higher body and visceral fat compositions (21.6 vs 17.6%, p = 0.008, and 10 vs 8%, p = 0.015, respectively) compared to their counterparts. Conclusion: Workers in hot and cool working environment are prone to nutrition- and health problems as well as dehydration, suggesting special attention to the provision of timely drinking water, and physical activity during working time.

Abstract

Background: Basal-like breast cancer is difficult to treat with standard regimen therapy, because it doesn’t express hormone receptors or epidermal growth factor receptors. Identification of oncogenesis pathway is expected to find molecules which can be used as target for therapy. One candidate molecule is topoisomerase-IIα whose expression is regulated by p53. This study aimed to compare the expression of mutant p53 proteins and topoisomerase IIα in basal-like and non basal-like breast cancer, and to determine the association between mutant p53 proteins and topoisomerase IIα in basal-like group. Methods: The samples were 40 formalin fixed paraffin embedded tissues from verified triple negative breast cancer tissue. The samples were divided into 2 groups, basal-like and non basal-like breast cancer, based on cytokeratin - 5 (CK-5) expression. Mutant p53 proteins and topoisomerase IIα were stained using immunohistochemistry method, scored and compared. Statistical test used SPSS software version 16 for descriptive statistics, kappa test, normality test, comparison of two mean, and categorical comparison. Results: Median (min-max) of mutant p53 protein expression in basal-like group was 21 (0-100), the non basal-like group was 2 (0-80), p = 0.061. Min-max of topoisomerase IIα in basal-like group was 263 (15-492), non basal-like group was 262 (0-481), p = 0.409. There was an association between mutant p53 positivity with breast cancer subtype (p = 0.027) and between mutant p53-topoisomerase IIα coexpression with breast cancer subtype (p = 0.018). Conclusion: Co-expression of mutant p53 with topoisomerase IIα has the role in one of the pathway of basal-like breast cancer pathogenesis.

Abstract

Background: Most of male infertility are caused by defect in sperm motility (asthenozoospermia). The molecular mechanism of low sperm motility in asthenozoospermic patients has not been fully understood. Sperm motility is strongly related to the axoneme structure which is composed of microtubules and supported by outer dense fiber (ODF) and fibrous sheath (FS) protein. The objective of this study was to characterize the ODF (ODF1 and ODF2) expression in asthenozoospermic infertile male and control normozoospermic fertile male.Methods: Asthenozoospermic samples (n=18) were collected from infertile patients at Andrology Lab, Cipto Mangunkusumo Hospital Jakarta and control were taken from normozoospermic fertile donor (n=18). After motility analyses by computer-assisted sperm analysis (CASA), semen were divided into two parts, for Western blot and for immunocytochemistry analysis. Antibody against ODF1 and ODF2 protein were used in both analyses.Results: Analysis of ODF1 protein expression showed bands with molecular weight of ~30 kDa and ODF2 ~85 kDa. The mean band intensity of ODF1 and ODF2 protein were lower in the asthenozoospermic group (AG) compared to normozoospermic group (NG). Moreover, both ODF proteins were less intense and less localized in the AG than NG. Sperm motility was lower in AG, compared to control NG, i.e. average path velocity (VAP) = 32.07 ± 7.03 vs 37.58 ± 8.73 µm/s, p = 0.455; straight line velocity (VSL) = 24.17 ± 6.90 vs 27.61 ± 4.50 µm/s, p = 0.317 and curvilinear velocity (VCL) = 45.68 ± 7.91 vs 55.55 ± 16.40 µm/s, p = 0.099.Conclusion: There is down-regulation of ODF1 and ODF2 protein expression and less-compact localization in AG sperm compared to the NG. These changes might have caused disturbances in the sperm motility as observed in this study.

Abstract

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.

Abstract

Background: The pathway of tumor necrosis factor alpha (TNFα), nuclear factor kappa beta (NF-κB), and cyclooxygenase-2 (COX-2) activation in releasing prostaglandins is suggested to be crucial for initiating labor in the pathogenesis of preterm labor. The aim of the study was to know whether there were mean differences of NF-κB, TNFα, and COX-2 expressions between preterm and term labor and also to know the correlation among them in preterm labor. Methods: A case-control study was performed from May 2013 to February 2014 in Arifin Achmad Hospital, Pekanbaru. There were 30 subjects with preterm labor as cases and 30 with normal labor as controls. All subjects had singleton gestation with maximum parity was three, age limit of 35 year-old, and spontaneous labor in both groups. Placental tissue was collected from all subjects and evaluated with hematoxylin eosin staining. The expressions of TNFα, NF-κB, and COX-2 in the tissue were assessed with immunohistochemical staining by counting the percentage of smeared cells by two experts. The expressions of TNFα, NF-κB, and COX-2 between case and control were compared using t-test and the correlation was analyzed with Pearson correlation coefficient. Results: Mean (SD) of expressions of TNFα (93.05% [12.68] vs 49.11% [27.33]), NF-κB (42.46% [27.29] vs 13.66% [17.77]), and COX-2 (88.75% [10.86] vs 46% [30.36]) were significantly higher in the preterm labor compared to term labor (p = 0.001). There was significant correlation between TNFα and NF-κB expression (r = 0.385; p = 0.036) and no correlation was found between NF-κB and COX-2 (p = 0.982) in preterm labor. Conclusion: High expressions of TNFα, NF-κB, and COX-2 in preterm labor showed to contribute in the onset of preterm labor. High TNFα may suggest that infection was a leading cause of preterm labor. This is supported with an increase in NF-κB activation will increase COX-2 and subsequently prostaglandins that result in premature labor.

Abstract

The most common site for malignant melanoma is skin, then eye and third is anorectal region. Primary anorectal malignant melanoma is still very uncommon. It is usually very aggressive and presents with altered bowel habit and rectal bleeding. Proctoscopy shows non-pigmented or lightly pigmented polypoid lesion. Histopathology is confirmatory. Early radical excision is mandatory. A 56 year-old female was presented with malignant melanoma of the lower third of rectum. We report this case for its rarity.

Abstract

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.
