Abstract

Community Service (PkM) is carried out by the Faculty of Medicine Universitas Methodist Indonesia by providing counselling how to prepare the Gold Generation. PkM was held on 8-11 June 2022 at Lumban Pea Timur, Balige,Toba District, North Sumatera. The method used is to provide counselling/lectures and provide motivation, then followed by question and answer to obtain results and solutions as a form of solving problems and obstacles faced. The results of PkM with counselling are very effective considering that there are still many people who do not get information about the meaning of Gold Generation. With this counselling, the public becomes aware of the Gold Generation. Thus, it is hoped that the people of Lumban Pea Timur will aware and know how to prepare the Gold Generation for their community

Abstract

The Kato-Katz technique is recommended for the diagnosis of helminth infections in epidemiological surveys, drug efficacy studies, and monitoring of control interventions. Leuenberger etc. were conducting a research to assess the comparability of the average amount of faeces generated by three Kato-Katz templates included in test kits from two different providers. Nine hundred Kato-Katz thick smear preparations were done; 300 per kit. Empty slides, slides plus Kato-Katz template filled with stool and slides plus stool after careful removal of the template were weighed to the nearest 0.1 mg. The average amount of stool that was generated on the slide was calculated for each template, stratified by standard categories of stool consistency (i.e. mushy, soft, sausage-shaped, hard, and clumpy). The average amount of stool generated on slides was 40.7 mg (95% confidence interval CI: 40.0 – 41.4 mg), 40.3 mg (95% CI: 39.7 – 40.9 mg) and 42.8 mg (95% CI: 42.2 – 43.3 mg) for the standard Vestergaard Frandsen template, and two different templates from the Chinese Center for Disease Control and Prevention (China CDC), respectively. Mushy stool resulted in considerably lower average weights when the Vestergaard Frandsen (37.0 mg; 95% CI: 34.9 – 39.0 mg) or new China CDC templates (37.4 mg; 95% CI: 35.9 – 38.9 mg) were used, compared to the old China CDC template (42.2 mg; 95% CI: 40.7 – 43.7 mg) and compared to other stool consistency categories. The average amount of stool generated by three specific Kato-Katz templates was similar (40.3 – 42.8 mg). Since the multiplication factor is somewhat arbitrary and small changes only have little effect on infection intensity categories, Leuenberger etc. suggested that the standard multiplication factor of 24 should be kept for the calculation of eggs per gram of faeces for all investigated templates.

Abstract

Numerous population-based studies have documented high prevalence of scabies in overcrowded settings, particularly among children and in tropical regions. Thus, a research has done by Karimkhani et al. providing an estimate of the global burden of scabies using data from the Global Burden of Disease (GBD) study 2015. The methods that had been used in the research including identification scabies epidemiological data sources with a Bayesian meta-regression modelling tool, DisMod-MR 2.1, to yield prevalence estimates. Combination of prevalence estimates with a disability weight, measuring disfigurement, itch, and pain caused by scabies, to produce years lived with disability (YLDs). With an assumed zero mortality from scabies, YLDs were equivalent to disability-adjusted life-years (DALYs). They estimated DALYs from 195 countries divided into 21 world regions, in both sexes and 20 age groups, between 1990 and 2015. The findings showed that scabies was responsible 0.21% of DALYs from all conditions studied by GBD worldwide. The world regions of East Asia (age-standardised DALYs 136.32), Southeast Asia (134.57), Oceania (120.34), tropical Latin America (99.94), and south Asia (69.41) had the greatest burden of DALYs from scabies. Mean percent change of DALY rate from 1990 to 2015 was less than 8% in all world regions, except North America, which had a 23.9% increase. The five individual countries with greatest scabies burden were Indonesia (age-standardised DALYs 153.86), China (138.25), Timor-Leste (136.67), Vanuatu (131.59), and Fiji (130.91). The largest standard deviations of age-standardised DALYs between the 20 age groups were observed in Southeast Asia (60.1), Oceania (58.3) and East Asia (56.5), with the greatest DALY burdens in children, adolescents, and the elderly. It was concluded that the greatest burden of scabies is greater in tropical regions, especially in children, adolescents, and elderly people. As a worldwide epidemiological assessment, GBD 2015 provides broad and frequently updated measures of scabies burden in terms of skin effects. These global data might help guide research protocols and prioritisation efforts and focus scabies treatment and control measures.

Abstract

Plasmodium falciparum cause febrile illness and severe disease with multiple organ failure and death when treatment is delayed. Antipyretic treatment is standard, and inducing hypothermia has been proposed to protect the brain in cerebral malaria. Here, Singhaboot, et al. investigated the temperature dependence of asexual-stage parasite development and parasite multiplication in vitro. Plasmodium falciparum strain TM267 was incubated for 2 hours (short exposure) or 48 hours (long exposure) at different temperatures (32OC, 34OC, 35OC, 38OC, 39OC, and 40OC). The starting parasite developmental stage (ring, trophozoite, or schizont) varied between experiments. The parasite multiplication rate (PMR) was reduced under hyper- and hypothermic conditions; after continuous exposure, the mean PMR ± SD was 9.1 ± 1.2 at 37OC compared with 2.4 ± 1.8 at 32OC, 2.3 ± 0.4 at 34OC, and 0.4 ± 0.1 at 40OC (P < 0.01). Changes in PMR were not significant after 2-hour exposure at temperatures ranging from 32OC to 40OC. Morphological changes in parasite cytoplasm and nucleus could be observed after long exposure to low or high temperature. After 48-hour incubation, rosette formation (≥ 2 uninfected red blood cells bound to infected red blood cells) was decreased at 34OC or 39OC compared with that at 37OC. In conclusion, both hyper- and hypothermia reduce PMR and delay erythrocytic stage development of P. falciparum, subsequently reducing rosette formation.

Abstract

Malaria masih menjadi masalah kesehatan di dunia. Pada tahun 2013, WHO memperkirakan terjadi 198.000.000 kasus malaria di seluruh dunia dan diperkirakan 584.000 di antaranya meninggal dunia. Selain dari keberadaan vektor, salah satu faktor pemberat dalam upaya mengatasi endemisitas penyakit menular ini adalah kemampuan dari Plasmodium dalam bertahan dari efek obat antimalaria, yang dikenal dengan kemampuan resistensi. Oleh karena itu, Dondorp, dkk. (2008) melakukan penelitian yang bertujuan mendeteksi dan mengidentifikasi adanya fenomena resistensi terhadap terapi tunggal artemisinin dan membuktikan keefektifan model ACT sebagai model terapi malaria yang terbaik. Penelitian tersebut dilakukan di Kamboja dengan alasan negara tersebut adalah bagian dari daerah perlintasan sungai Mekong, yang menjadi wilayah endemis malaria di Asia Tenggara.Metodologi yang digunakan oleh Dondorp, dkk adalah desain RCT, mengambil total 80 subyek penelitian yang didiagnosis menderita malaria falciparum yang tinggal di 2 wilayah, 40 subyek di Pailin dan 40 subjek di Wang Pha. Masing - masing kelompok dibagi menjadi 4 kelompok kecil. Model terapi yang diberikan adalah artesunate tunggal 2mg/kg berat badan/hari selama 7 hari dan artesunate 4 mg/kg berat badan/hari selama 3 hari dilanjutkan dengan mefloquine 15 mg/kg berat badan pada hari ke-3 serta 10 mg/kg berat badan/hari pada hari ke-4 - 7. Analisis data menggunakan uji student’s t, chi-square, dan Mann-Whitney. Fenomena resistensi dilihat dari waktu bersihan parasit yang didapatkan dengan estimasi Kaplan-Meier dan Wilcoxon-Breslow-Gehan.Kelompok subyek yang mendapat terapi tunggal artemisinin mempunyai waktu bersihan parasit yang lebih lama dibandingkan dengan kelompok subyek yang mendapat ACT (nilai median 84 jam; 48 jam; P < 0,001). Model ACT juga masih terbukti efektif dibandingkan dengan model terapi tunggal artemisinin dilihat dari laju rekrudesensi di kedua kelompok yang lebih rendah (5%; 30% dan 5%; 10%; P < 0,001). Fenomena resistensi artemisinin sudah mulai muncul di Asia Tenggara. Hal ini perlu diwaspadai oleh pemerintah Indonesia mengingat wilayah geografis dan keberadaan vektor penyakit. Model ACT masih merupakan model terapi terbaik dalam mengobati malaria.

Abstract

Cataracts are the leading cause of blindness worldwide and a major public health challenge, particularly among underserved populations in Indonesia. This community service activity aimed to restore vision and improve quality of life for underprivileged cataract patients through free cataract surgery provided by Lions Club Medan Angkasa and Lions Club Tebing Tinggi Royal in collaboration with Tebing Tinggi Police Department and Bhayangkara Hospital. The surgical camp was conducted on Sunday, April 27, 2025, at RS Bhayangkara Tebing Tinggi, in commemoration of the 79th Bhayangkara Anniversary. The activity included preoperative screening, phacoemulsification cataract surgery, pterygium excision, and postoperative care. A total of 79 patients participated: 73 cataract cases and 6 pterygium cases. Experienced ophthalmologists successfully performed all surgeries using modern surgical techniques. Post-operative evaluation showed significant visual improvement in 98% of patients. This initiative demonstrates the effectiveness of multi-sector collaboration in addressing preventable blindness and highlights the crucial role of community-based organizations in supporting healthcare access for marginalized populations.

Abstract

Urinalysis is a basic test for patients with urinary tract infections (UTIs). Ninety-five percent of UTIs are caused by E. coli. The incidence rate of UTIs in Indonesia among adolescents aged 10-18 years is 35%-42%, and among young adults aged 19-22 years, it is 27%-33%. UTI diagnosis is confirmed by urine culture, where a bacterial count of > 10⁵ colonies per milliliter (CFU/ml) is detected. The urinalysis shows leukocyturia and a positive nitrite test. Bacteria capable of converting nitrate to nitrite include Escherichia coli, Enterobacter, Citrobacter, Klebsiella, and Proteus species. This study used an observational analytical study with a cross-sectional design and retrospective approach. The study sample consisted of UTI patients who underwent leukocyte, nitrite, and urine culture tests recorded in the medical records of the Clinical Pathology Department at Dr. Pirngadi General Hospital in Medan. Out of 60 urine culture samples, 12 samples showed no bacterial growth. The results showed that the majority of UTI patients were female, totaling 36 individuals (60%), compared to 24 males (40%). The age group of 51-70 years (54%) had the highest number of UTI patients. Positive leukocytes experienced UTI (68.8%) compared to negative leukocytes (p-value 0.001). Compared to negative nitrites, 58.3% of positive nitrites had a UTI (p-value 0.001). In this study, the most common bacteria causing UTI were Klebsiella pneumoniae (43%), Enterococcus faecalis (17%), and Escherichia coli (8%). In 60 urine culture samples, the most common bacteria causing UTIs were Klebsiella pneumoniae (43%), Enterococcus faecalis (17%), and Escherichia coli (8%). Leukocytes were positive in 68.8% of cases of UTI compared to negative leukocytes, with a p-value of 0.001. Nitrites were positive in 58.3% of cases of UTI compared to negative nitrites, with a p-value of 0.001.

Abstract

Recent advances in tests for the sexually transmitted protozoan parasite Trichomonas vaginalis have increased opportunities for diagnosis and treatment of this important sexually transmitted infection. This review summarizes current available tests, highlighting their performance characteristics, advantages, and limitations. The recent development of molecular tests for the detection of T vaginalis, including rapid antigen detection and nucleic acid amplification tests, has significantly improved the quality of diagnostics for trichomoniasis, particularly in women. In light of the expanded menu of testing options now available, improved recognition and better control of trichomoniasis are in sight, which should enable the eventual reduction of adverse reproductive consequences associated with T vaginalis infection.

Abstract

Medullary Thyroid Carcinoma (MTC) is a type of thyroid cancer originating from C cells, while Poorly Differentiated Thyroid Carcinoma (PDTC) is a more aggressive form with poor differentiation. The transformation between these two types can affect prognosis and treatment strategies. This study analyzes an 18-year-old female patient presenting with neck swelling and difficulty swallowing. The initial diagnosis of MTC was established through fine-needle aspiration biopsy (FNAB), and after surgical resection, histopathological analysis was conducted to evaluate any transformation to PDTC. Histopathological findings revealed MTC areas with high calcitonin-producing C cells. However, there were also areas exhibiting characteristics of PDTC, including increased mitotic activity, necrosis, and loss of calcitonin expression. This transformation indicates a shift from a more indolent cancer form to a more aggressive one. The transformation from MTC to PDTC in a young patient underscores the importance of careful monitoring and thorough histopathological evaluation. Appropriate management and understanding of these changes are crucial for improving treatment outcomes. Further studies are needed to elucidate the molecular mechanisms underlying this transformation.
