Background: E6 and E7 are oncoproteins of HPV16. Natural amino acid variation in HPV16 E6 can alter its carcinogenic potential. The aim of this study was to analyze phylogenetically E6 and E7 genes and proteins of HPV16 from Indonesia and predict the effects of single amino acid substitution on protein function. This analysis could be used to reduce time, effort, and research cost as initial screening in selection of protein or isolates to be tested in vitro or in vivo.Methods: In this study, E6 and E7 gene sequences were obtained from 12 samples of Indonesian isolates, which were compared with HPV16R (prototype) and 6 standard isolates in the category of European (E), Asian (As), Asian-American (AA), African-1 (Af-1), African-2 (Af-2), and North American (NA) branch from Genbank. Bioedit v.7.0.0 was used to analyze the composition and substitution of single amino acids. Phylogenetic analysis of E6 and E7 genes and proteins was performed using Clustal X (1.81) and NJPLOT softwares. Effects of single amino acid substitutions on protein function of E6 and E7 were analysed by SNAP.Results: Java variants and isolate ui66* belonged to European branch, while the others belonged to Asian and African branches. Twelve changes of amino acids were found in E6 and one in E7 proteins. SNAP analysis showed two non neutral mutations, i.e. R10I and C63G in E6 proteins. R10I mutations were found in Af-2 genotype (AF472509) and Indonesian isolates (Af2*), while C63G mutation was found only in Af2*.Conclusion: E6 proteins of HPV16 variants were more variable than E7. SNAP analysis showed that only E6 protein of African-2 branch had functional differences compared to HPV16R.

BackgroundThymoma is the most common neoplasm found in thymus gland and is classified into 5 main histopathological types, A, AB, B1, B2,and B3. Thymomas are most commonly found in the anterior mediastinum and accompanied with myasthenia gravis. The aim of thisstudy was to find out clinical feature and histopathological characteristics of thymomas in Department of Anatomical Pathology, Facultyof Medicine, University of Indonesia/Dr. Cipto Mangunkusumo Hospital (FKUI/RSCM) in 2014-2018.MethodsThis is a descriptive study, using a cross-sectional design. Clinical and histopathological data obtain from the medical records andarchives of the Department of Anatomical Pathology of FKUI/RSCM. Clinical data consists of age, sex, tumor location, clinicalsymptom, concomitant disease, metastasis, and treatment. Histopathological assessment consists of histopathology type using WorldHealth Organization criteria and staging using Masaoka-Koga staging system.ResultsThere were 31 thymoma cases matched the inclusion criteria. Nineteen (61.3%) of 31 cases were women. The mean age of thesubjects was 46.7 years old. A total of 12 cases (37.5%) had muscle weakness due to myasthenia gravis as chief complaint and 21cases (67.7%) of tumor mass in the anterior mediastinum. There 9 cases of type AB and 2 cases of type B2.ConclusionThymoma is more common in women with an average age of 46.7 years. The most common paraneoplastic syndrome is myastheniagravis and mostly found in the anterior mediastinum. The most common histopathologic type is type AB, while type B2 is the least.

Background Sinonasal papilloma is a benign tumor arising from Schneiderian epithelia in sinonasal mucosa. It has the propensity towards malignant transformation. This preliminary study aims to report clinicopathological aspects of sinonasal papilloma and its malignant transformation rate. Methods A descriptive, cross-sectional study was conducted in Anatomical Pathology Department, FKUI/RSCM over a period of 2014-2019) A total of 127 histologic specimens with diagnosis of sinonasal papilloma obtained from 80 cases. Results The prevalence of sinonasal papilloma among all sinonasal neoplasms is 17.6%. Inverted papilloma was the most common histologic type 91.3%, exophytic papilloma 6.3% and oncocytic papilloma 2.5%, among male (70%), age rate 50 years old. Malignant transformation of squamous cell carcinoma 12.5%, and recurrence 21.3%, nasal congestion was the most complaint 50%. Cases were usually in T3 of Krouse stage 37.5% and managed with functional sinus endoscopic surgery 51.3%. Histological parameters were grade II 54.4%, surface keratinization 17.5%, bony trabeculae 41.3%, nasal polyps 20% and dense lymphocytic infiltrates 53.8%, foam cell infiltrates 2.5%. Mild to moderate dysplasia 8.8% and severe dysplasia 18.8%. Conclusion Sinonasal papilloma was rare sinonasal benign tumor. Inverted papilloma type was local aggressive, recurrence, dysplastic and malignant transformation, among male, age 50 years old, main complaint of nasal congestion, in Krouse stage T3, and managed by Functional Sinus Endoscopy Surgery (FSES

Background Studies suggest that the most common type of nasopharyngeal carcinoma (NPC) is WHO-3, which is strongly associated with Epstein-Barr virus (EBV). Objective To assess NPC patient characteristics in a national general referral hospital in Indonesia, with regards to EBV DNA load and treatment response. Methods Twenty-three pediatric patients diagnosed with NPC were included in the study. Data collected were history, physical examination, tissue biopsy, CT scan, staging and EBV DNA load from nasopharyngeal (NP) brushing as well as blood specimens. The NP brushing, blood specimens and CT scan evaluations were done two months post-treatment. Results Pediatric patients with symptoms such as blood tinged secretion, lymph node enlargement, and nasal congestion were more likely to have higher EBV DNA loads in their NP brushings (P<0.05) (including T3 and higher). Despite significant reduction of EBV DNA load in NP brushing post-treatment, it was not associated with treatment response, as evaluated by CT scan. Conclusion Higher DNA load from NP brushings is associated with a higher tumor stage. Larger sample size and follow-up data are needed to assess the usefulness of EBV DNA load assessment in pediatric patients.

Background: Cervical cancer is the fourth most common cancer among women across the world. Recent studies have shown that cervical cancer is not only caused by persistent infection of human papillomavirus (HPV), but sexually transmitted infections (STIs) also play a role in the pathogenesis of abnormal cervical cells. STIs frequently occur with no specific symptoms, such as the infections caused by Chlamydia trachomatis and Mycoplasma hominis. Asymptomatic STIs could lead to persistent infection. Persistent infections caused by STIs have been hypothesised to increase the access of HPV into the deeper cervical tissue and cause cervical cell abnormalities. Therefore, we conducted this study to assess the association between C. trachomatis and M. hominis infections and abnormal cervical cells. Methods: A cross-sectional study was performed on 58 outpatients at the Department of Obstetrics and Gynecology, Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia. Abnormal cervical cells were detected by a liquid-based cytology Pap smear, and bacterial identification was done by conducting conventional duplex polymerase chain reaction (PCR). Results: 58 patients, 14 (24.1%) showed abnormal cervical cells, whereas 44 (75.9%) patients showed normal cervical cells. The conventional duplex PCR demonstrated a positive result for C. trachomatis and M. hominis bacterial infections in only 1 (7.1%) and 2 (14.3%) patients with abnormal cervical cells, respectively. The statistical analysis revealed no significant association between the bacterial infections and the abnormal cervical cytology in the patients (p > 0.05). Conclusions: Infections caused by C. trachomatis and/or M. hominis were not associated with abnormal cervical cells.
