Abstract

Diagnosis of Tuberculous (TB) lymph adenitis is still problematic due to paucibacillar. Since histopathological biopsy examination is relatively expensive and needs times, FNA is being more frequently chosen. The specimen from FNA can be processed for cytological and PCR tests, but there is no data available describe the characteristic of the result of both methods. Hence, study is needed in order to improve knowledge and health services. A cross sectional study had been conducted from January 1st   until December 31st   , 2011, at Anatomical Pathology Laboratory of Medical School of Udayana University/Sanglah Hospital and Biomolecular Laboratory of Medical School of Udayana University. The subjects were all patients with clinical diagnosis TB lymph adenitis who met the eligibility criteria. During 6 months, there were 46 patients included in the study. They were 65% female and 35% male. The age was ranging from 5 years old until 83 years old and 30-39 years old age group was the highest in number (39%). Positive cytology result was found in 22 cases (48%), while PCR test revealed no positive result. There was significant diference between positive and negative cytology test in pain sensation category, conversely in onset, number of enlarged lymph node/s, localization, conglomeration and fixation categories. If every single clinical character was marked with score 1, node/s with accumulative scores 4-6 showed no different cytology result with node/s with score 1-3. This study shows that in detecting TB lymph adenitis using FNA specimen, cytology test was be#er than PCR

Abstract

Karsinoma sel basal (KSB) merupakan keganasan kulit non-melanotik tersering dan mempunyai kaitan erat dengan paparan sinar ultra violet (UV). Keganasan ini berasal dari sel-sel pluripotensial stratum basalis epidermis maupun selubung akar folikel rambut. Gambaran klinis dan histopatologis terdiri dari KSB tipe klasik (noduler) dan KSB varian (tipe superfisial, fibroepithelial, KSB dengan diferensiasi adneksal, basoskuamous, infiltrating, morpheaform).Kanker pada tubuh manusia muncul karena adanya mutasi genetik pada gen-gen yang terlibat dalamkontrol pertumbuhan sel, seperti onkogen, tumor suppressor gene, gen apoptosis, dan DNA repair gene.Pada kebanyakan kasus KSB, gen yang tersering mengalami mutasi adalah tumor suppressor genep53. Mutasi ini timbul akibat paparan langsung sinar UV, bergantung pada dosis, durasi dan intensitas paparan.Gen p53 dikenal dengan sebutan guardian of the genome, karena fungsinya sebagai sensor terhadapterjadinya kerusakan DNA. Adanya kerusakan DNA menginduksi aktivasi p53 untuk menghentikan siklus sel saat memasuki fase G1, sehingga memberikan kesempatan kepada DNA repair proteinbekerja memperbaiki kerusakan DNA. Lebih dari itu, p53 juga mengaktivasi gen GADD45 (growth arrest and DNA damage) untuk membantu perbaikan DNA. Jika perbaikan gagal, p53 akanmengarahkan sel dengan DNA yang rusak ke mesin apoptosis.Pada sel-sel basal terpapar UV, gen p53 mengalami mutasi dan inaktivasi. Karena itu, sel-sel dengan DNA yang mengalami kerusakan non-lethal akan mengalami ekspansi klonal sehingga tumbuh menjadilesi pra kanker dan akhirnya kanker (KSB). [MEDICINA 2014;45:38-42]

Abstract

Cervical cancer is the second most common malignancy in women with increasing morbidity and mortality rate. VEGF is known as one of pro-angiogenic factors that induce angiogenesis in various malignancy. VEGF overexpression is associated with poor prognosis and plays an important role in cervical cancer progression. This study aimed to investigate the association between VEGF expression and pathological parameters of squamous cell carcinoma of uterine cervix in Sanglah General Hospital Denpasar. This is a cross-sectional study design. The sampel size was 36 paraffin blocks which were selected by consecutive sampling. Pathological parameter data were divided into 2 categories; tumor size (£4 cm, >4 cm), tumor extension (intra and extra-uterine), lymphatic vascular invasion (positive, negative), vascular density (low, high) and lymph node metastasis (positive, negative). VEGF expressions were examined by imunohistochemical technique and evaluated by Histo-Score method. All variables were analyzed by Chi-square analysis with significance value p <0.05. Chi-square analysis revealed an association between tumor size and VEGF expression (p=0.035). In addition, large tumor size (>4 cm) has 2.17 times probability of causing high VEGF expression. VEGF expression were not associated with tumor extension (p=0.502), lymphatic vascular invasion (p=0.346), vascular density (p=0.364) and lymph node metastasis (p=0.209). This study has proved that tumor size is associated with VEGF expression. Large tumor size has greater risk of causing high VEGF expression therefore anti-VEGF targeted therapy could be proposed in large tumor size. There were no association between VEGF expression and tumor extension, lymphatic vascular invasion, vascular density and lymph node metastasis. Keywords: VEGF expression, squamous cell carcinoma, uterine cervix.

Abstract

Karsinoma Tiroid Papiler (KTP) merupakan keganasan tiroid tersering di seluruh dunia. Sebagian besar KTP memiliki prognosis baik, sekitar 10% kasus menunjukkan gambaran klinikopatologis agresif, dan sebagian terkait mutasi promoter Telomerase Reverse Transcriptase (TERT). Tujuan penelitian ini adalah membuktikan hubungan antara ekspresi TERT dengan berbagai parameter klinikopatologis agresivitas KTP klasik di RSUP Sanglah Denpasar. Penelitian ini menggunakan rancangan analitik potong lintang. Sampel adalah semua penderita KTP klasik yang dilakukan pemeriksaan histopatologi di Laboratorium Patologi Anatomi RSUP Sanglah tahun 2017-2019 dengan besar sampel 43. Ekspresi TERT dinilai dengan pemeriksaan imunohistokimia, interpretasi menggunakan H-score. Hubungan ekspresi TERT dinilai pada parameter agresivitas, usia, ukuran tumor, perluasan ekstratiroid, LVI, metastasis KGB regional,. Dianalisis dengan uji Chi-square dengan nilai kemaknaan p<0,05. Hasil penelitian didapatkan hubungan yang signifikan antara ekspresi TERT dengan agresivitas KTP klasik (p=0,041). Terdapat hubungan yang signifikan pula antara ekspresi TERT dengan parameter perluasan ekstratiroid (p=0,010), dan metastasis KGB (p=0,036), namun tidak terdapat hubungan yang signifikan dengan parameter usia (p=0,202), ukuran tumor (p=0,780), dan LVI (p=0,137). KTP klasik dengan ekspresi TERT tinggi memiliki kemungkinan 1,84 kali lebih besar untuk perluasan ekstratiroid, 2,36 kali lebih besar untuk metastasis KGB, dan 2,53 kali lebih besar untuk menjadi agresif. Sebagai simpulan, terdapat hubungan antara ekspresi TERT dengan agresivitas KTP klasik parameter perluasan ekstratiroid dan metastasis KGB regional. Diharapkan pemeriksaan TERT dipertimbangkan untuk dikerjakan rutin pada KTP klasik disamping dari penilaian faktor-faktor agresivitas klinikopatologi, serta sebagai salah satu penanda prognosis buruk pada KTP klasik dalam memprediksi risiko kekambuhan.Kata kunci : TERT, Karsinoma Tiroid Papiler Klasik, Agresivitas, IHK, Klinikopatologis

Abstract

Background: Kakadu cream contained 0,1% Kakadu plum (Terminalia ferdinandiana) extract with a high content of phenolic compound, flavonol, tocopherol, luthein, chlorophyll, and ellagic acid has potential to prevent the Ultraviolet-B (UV-B) effect on skin aging acceleration. To date, there’s no in vivo experiment on the effect of kakadu plum extract on collagen nor matrix metalloproteinase-1 (MMP-1). This research aims to evaluate the effectiveness of Kakadu cream administration in inhibiting the increase of MMP-1 expressions and prevent the decrease of collagen amount in mice (Mus musculus) skin exposed to UV-B. Methods: An experimental study with a post-test only control group design was employed in 36-male-mice, 6-8 weeks old, weighing 20-25 grams. The samples were divided randomly into two groups, a control group given base cream and the study group, given Kakadu cream 0,1% on their shaved backs, 1 cm2 in size as the UV-B exposure's location. The UV-B irradiation was done three times a week for 4-weeks. The base and Kakadu cream were given twice a day. Comparative analysis was carried out to compare MMP-1 expression and collagen amount in both groups. Results: The results show that the mean of MMP-1 expression on the study group was significantly lower compared to control group (p<0.001). The mean collagen amount was significantly higher in the study group than in the control group (p< 0,001). Conclusion: From the results, can be concluded that Kakadu cream inhibited the increase MMP-1 expression and prevent the decrease of collagen amount in mice skin exposed to UV-B.

Abstract

Background: Centella asiatica has been popularly used in cosmetic products, especially due to its antioxidant benefits in soothing and healing wounds. However, the inhibition of melanogenesis in the content of Centella asiatica has not been widely studied. This study aimed to prove the effectiveness of 10% Centella asiatica cream on male Guinea pig (Cavia porcellus) skin exposed to UVB. Methods: The randomized posttest-only control group study was conducted on 36 Guinea pigs aged 3-months, body weight 300-350 grams with a healthy skin condition. They were randomly divided into two groups; each consists of 18 Guinea pigs. The first group was a control group given base cream 20-minutes before and 4-hours after UVB exposure, 3-times-a-week for two weeks. The second group was the treatment group given 10% Centella asiatica cream and expose to UVB with the same procedure. The histopathological preparations were made using a punch biopsy after intervention was completed. Immunohistochemical staining was performed to measure the expression of microphthalmia-associated-transcription-factor (MITF) and Masson-Fontana to measure the amount of melanin. Data analysis was conducted to compare the results in both groups. Results: The treatment group had a significantly lower mean MITF expression (13.61 ± 5.36 vs. 27.24 ± 6.50%) and melanin amount (5.95 ± 3.81 vs. 16.59 ± 5.77%) (p < 0.001) compared to the control group. Conclusion: The administration of cream consists of Centella asiatica extract 10% effectively inhibits the expression of MITF and prevented the increase of melanin amount in male guinea pigs (Cavia porcellus) exposed to UVB.

Abstract

Background: Eucalyptus globulus essential oil contained 1,8-cineol, which may accelerate wound healing. This study aimed to prove Eucalyptus globulus essential oil's effect on increasing neovascularization and Vascular Endothelial Growth Factor (VEGF) expression in Wistar rats skin exposed to ultraviolet B (UVB). Methods: A Post-test only controls group study design was applied on 36 male Wistar rats, aged 3-4 months old, weighing 150-200 grams. The animal subject was exposed to UVB (65 mJ/cm2, 65 seconds for seven days), injured on their back using a punch biopsy with a diameter of 10 mm, and divided into two groups. For seven days, on the wound, the control group was given 2 cc of 0.9% NaCl twice a day, while the treatment group was given Eucalyptus globulus essential oil (2 cc). Both groups were given oral Amoxicillin three times a day. The skin tissue was taken on day eight to assess neovascularization and VEGF expression. Results: The results show that neovascularization in the treatment group was higher than in the control group (p < 0.05). Meanwhile, the median VEGF expression in the treatment group was also higher than in the control group (p < 0.05). Conclusions: Topical administration of Eucalyptus globulus essential oil increased neovascularization and VEGF expression in the skin of male Wistar rats injured and exposed to UVB. Further research is needed to assess the effectiveness of the essential oil in enhancing neovascularization and VEGF expression in humans with multiple exposures at different doses to optimize the wound-healing effect.

Abstract

Background: c-MET is a tyrosine kinase receptor that binds specifically to its ligand, namely hepatocyte growth factor (HGF). c-MET signaling deviations play a role in the progressivity of a wide variety of malignancies including bladder cancer. This study aims to determine the relationship between c-MET expression with the histological differentiation and depth of invasion in infiltrating urothelial carcinoma of bladder.Methods: This study was a cross-sectional analytical study with 42 sample sizes. The samples were taken from a paraffin block of patients with infiltrating urothelial carcinoma of the bladder, that has performed resection and histopathological examination who were examined at the Anatomical Pathology Laboratory of Sanglah Hospital Denpasar from 2015-2020. The c-MET expression was examined by immunohistochemical staining of c-MET and evaluated using the H-score method. Data were analyzed using SPSS version 20 for Windows.Results: Fisher's Exact test showed a statistically significant association between c-MET expression and the histological differentiation grade (p = 0.000). There was also a significant association between c-MET expression and depth of invasion with the Chi-Square test (p = 0.016), the Prevalence Ratio (PR) was 2.0 (95% CI = 1.2-3.6).Conclusion: In conclusion, there is an association between c-MET expression with the histological differentiation grade and depth of invasion in the infiltrating urothelial carcinoma of bladder. High c-MET expression had twice the risk of developing advanced invasion. Latar Belakang: c-MET merupakan reseptor tirosin kinase yang berikatan secara spesifik dengan ligannya, yaitu faktor pertumbuhan hepatosit (HGF). Penyimpangan c-MET signaling diketahui berperan dalam agresivitas berbagai macam keganasan termasuk kanker kandung kemih. Penelitian ini bertujuan untuk mengetahui hubungan antara ekspresi c-MET dengan derajat diferensiasi histologi dan tingkat kedalaman invasi pada infiltrating urothelial carcinoma kandung kemih.Metode: Penelitian ini merupakan studi analitik potong lintang dengan besar sampel adalah 42, yang berasal dari blok parafin penderita infiltrating urothelial carcinoma kandung kemih yang diperiksa histopatologi di Laboratorium Patologi Anatomi RSUP Sanglah Denpasar dari 2015-2020. Ekspresi c-MET diperiksa dengan pengecatan imunohistokimia c-MET dan dievaluasi menggunakan metode H-score. Data dianalisis dengan SPSS versi 20 untuk Windows.Hasil: Uji Fisher’s Exact menunjukkan hubungan yang bermakna secara statistik antara ekspresi c-MET dengan derajat diferensiasi histologi (p=0,000). Didapatkan juga hubungan yang bermakna antara ekspresi c-MET dengan tingkat kedalaman invasi dengan uji Chi-Square (p=0,016), prevalence ratio 2,0 (IK 95%=1,2-3,6).Kesimpulan: Sebagai simpulan terdapat hubungan antara ekspresi c-MET dengan derajat diferensiasi histologi dan tingkat kedalaman invasi pada infiltrating urothelial carcinoma kandung kemih. Ekspresi c-MET tinggi memiliki risiko dua kali lebih besar mengalami invasi lanjut. c-MET diharapkan dapat menjadi faktor prognostik yang bermanfaat dalam penatalaksanaan infiltrating urothelial carcinoma kandung kemih.

Abstract

Background: Colorectal carcinoma is a malignant epithelial tumor of the large bowel that occurs due to extrinsic and intrinsic factors. BRAF V600E gene mutation was found in about 10-15% of colorectal carcinoma. This mutation was associated with aggressive biologic behaviors, metastasis and lesser responsiveness to EGFR inhibitors therapy. This study aims to determine the association between BRAF V600E expression with metastasis and the degree of differentiation of colorectal adenocarcinoma.Methods: This cross sectional study involved 43 samples of adenocarcinoma colorectal patients who had histopathological examinations in the period 2018-2019. Immunohistochemical were performed to assess the expression of BRAF V600E. This expression was concluded positively if 75% or more tumor cells showed intense cytoplasmic staining. Data were analyzed using SPSS version 20 for Windows.Results: Within 43 colorectal adenocarcinoma cases, it was found 7 cases (16.3%) had a positive expression of BRAF V600E. This expression was found in metastasis cases (7/25), not found in cases without metastasis (0/18). There was an association between BRAF V600E expression and metastasis (p=0.014). The positive expressions of BRAF V600E were only found in low-grade differentiation (7/35 cases), were not found in high-grade differentiation (0/8 cases), and no association between BRAF V600E mutation and the degree of differentiation (p=0.167).Conclusion: There was an association between BRAF V600E expression and metastasis of colorectal adenocarcinoma. There was no significant association between BRAF V600E expression and the degree of differentiation of colorectal adenocarcinoma. Latar Belakang: Karsinoma kolorektal merupakan suatu tumor ganas epitelial usus besar yang terjadi akibat pengaruh dari faktor ekstrinsik dan intrinsik. Mutasi gen BRAF V600E ditemukan pada sekitar 10-15% kasus karsinoma kolorektal. Mutasi ini berkaitan dengan perilaku biologik agresif, metastasis, serta kurangnya respon terhadap terapi dengan inhibitor EGFR. Penelitian ini bertujuan untuk mengetahui adanya hubungan antara ekspresi BRAF V600E dengan metastasis dan derajat diferensiasi adenokarsinoma kolorektal.Metode: Penelitian menggunakan rancangan analitik potong lintang dengan 43 sampel penderita adenokarsinoma kolorektal yang telah dilakukan pemeriksaan histopatologi pada periode tahun 2018-2019. Pulasan imunohistokimia dikerjakan untuk menilai ekspresi BRAF V600E. Ekspresi BRAF V600E dinyatakan positif jika 75% atau lebih sel tumor mununjukkan pulasan sitoplasma dengan intensitas kuat. Data dianalisis dengan SPSS versi 20 untuk Windows.Hasil: Dari 43 kasus, ditemukan 7 kasus (16,3%) dengan ekspresi BRAF V600E positif. Ekspresi ini hanya dijumpai pada kasus dengan metastasis (7 dari 25 kasus), tidak dijumpai pada kasus tanpa metastasis (0 dari 18 kasus). Didapatkan hubungan bermakna antara ekspresi BRAF V600E dengan metastasis (p=0,014). Ekspresi BRAF V600E positif hanya ditemukan pada kasus derajat diferensiasi rendah (7 dari 35 kasus), tidak ditemukan pada derajat tinggi (0 dari 8 kasus), dan hubungan tersebut tidak bermakna secara statistik (p=0,167).Kesimpulan: Terdapat hubungan antara ekspresi BRAF V600E dengan metastasis pada adenokarsinoma kolorektal. Tidak terdapat hubungan antara ekspresi BRAF V600E dengan derajat diferensiasi pada adenokarsinoma kolorektal.
