The primary cause of hypothyroidism in the ​​sufficient iodine area is Hashimoto's thyroiditis. Hashimoto's thyroiditis, also known as chronic autoimmune thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune condition in which B cells and T cells slowly destroy the thyroid gland. To determine the diagnosis, we need the clinical, laboratory, cytological, and/or histopathology profiles. It aims to distinguish Hashimoto's thyroiditis from other diseases such as nontoxic goiter and Graves' disease. This retrospective descriptive study used data from the medical record of Dr. Soetomo General Hospital from 2015-2020. This study used total sampling and got 18 patients in total. The patients were mostly females (n=15), in the age group of 40-49 years old (n=8). The main complaint was an enlargement or nodule in the neck. The TSH (thyroid stimulating hormone) levels were majorly higher than the normal range (n=8) meanwhile the FT4 levels were mostly normal (n=6) and low (n=6). The positivity of TPOAb (antibody against thyroid peroxidase) is merely found in one patient. The majority of the result of the Doppler ultrasound examinations revealed Hashimoto’s thyroiditis (n=7). FNAB (fine needle aspiration biopsy) was performed on 11 patients. A histopathology examination was also conducted on 9 patients who underwent thyroidectomy. All of the cytology and histopathology examinations confirmed Hashimoto’s thyroiditis. Non-Hodgkin Lymphoma was found to coexist with 2 Hashimoto's thyroiditis cases. The findings were similar to the previous studies, except that among all the subjects, those who are 40-49 in age were primarily found in this study.

Background: Obesity has been one of the most concerning world-wide health problems due to its increase in number every year. In order to raise public awareness, direct face-to-face education is one of the methods that can be implemented. Ongoing COVID-19 pandemic and government's countermeasures, however, limit offline activities, driving people to use online educational platforms instead, which has not been explored as much. Therefore, this study aims to examine the impact towards knowledges, attitudes and practices of productive age-population after receiving virtual education regarding obesity. Methods:A quasi-experimental study was conducted to a group of productive-age-population in Surabaya, Indonesia.The population received an intervention through virtual education, and results were collected using a questionnaire, comparing the pre-test to the post-test results.Results: Results from 19 participants who met the eligibility criteria were analysed using paired t-test for knowledge and Wilcoxon signed-rank test for attitude and practice. Despite no significant differences in knowledge and attitude domains (p = 0.077; p = 0.640), the result shows a significant increase in the attitude domain (p = 0.038) after intervention. Conclusion:This study showed an improvement of attitude regarding obesity after receiving online education. However, the results were not the same in knowledge and practice domains. Therefore, further studies regarding the impact of online education method are necessary to confirm the current findings.
