Background: Measuring thyroid hormone levels is essential and helpful in the diagnosis of thyroid diseases. Case presentation: We had a patient with undetectable serum TSH level by the Siemens immunoassay, whereas by ELISA and Roche-Abott immunoassay, serum level of TSH was in the normal range. Conclusion: If the result of TSH level revealed very low or undetectable through one specific method, it should not be considered necessarily as a symptom of hyperthyroidism. It is to be requested to measure by the other methods with other devices too.

Background: Helicobacter pylori is a slow-growing micro-aerophilic gram-negative organism found in stomach and duodenum. It is also associated with a number of stomach-duodenal diseases. Material and Methods: There are invasive and non-invasive methods for detecting Helicobacter pylori infections. In a 13- months period, 101 patients with clinical signs of infection confirmed by biopsy and Rapid Urease test as well as culture were included to this study. Results: There were significant correlations between breath urease test, anti-Helicobacter pylori serum IgG and IgA as well as fecal Helicobacter pylori Ag with gold standard method,(P=0.001) Moreover, there was significant correlation between monocytosis (P= 0.05) and gold standard method. Conclusion: Based on studies conducted on patients with Helicobacter pylori infection, noninvasive diagnostics methods can be useful in the diagnosis of Helicobacter infections rather than evaluating anti-Helicobacter pylori serum IgM and also increased blood monocytes could be a reliable confirmation for detection. Furthermore, showed monocytosis must be considered as a Helicobacter pylori infection at first step in area with high infected percentage.

Background: The first human case of COVID-19 was reported on 19 February 2020 in Iran, since then the number of infected cases has dramatically increased to about 1.800 million and about 62 000 deaths, also elderly people have accounted for the largest frequency of mortality. Objective: This study aims to evaluate the prevalence of Covid-19 RT-PCR positive among Iranian patients and to evaluate the most important clinical symptoms of identified patients based on age, gender, and their background diseases to be used as an aid for early diagnosis. Methods: During 9 months, swab samples of 11 034 patients’ nasopharynx and oropharynx secretions were obtained and were referred to the laboratory for Covid-19 RT-PCR test. In addition, the history of signs and symptoms from patients was recorded. Results: In total, 11 034 Covid-19 RT-PCR tests that performed, 3358 samples had positive results (30.4%). Headache was the most commonly reported, which was found in 42.5% of our cases. Fever was the second most common symptom among the patients studied, with a prevalence rate of 36.2%. Conclusion: In this study, almost 30% of symptomatic patients had positive Covid-19 RT-PCR test results. Headache was the most common symptom; also diarrhea and nausea were the least common symptoms among patients under this study.
