Trichobezoar Found Accidently while Diagnosing Resistance to Thyroid Hormone.

Introduction: Bezoars are masses of indigestible foreign material in the gastrointestinal tract, usually in the stomach. These materials could be indigestible fruits, hair, milk products, or tablets. In children, the most common type of bezoar is trichobezoar (formed from hair). Case Presentation: We describe a female patient who has been complaining about deterioration of mood, collapse without losing consciousness, scotomas, and cardiac arrhythmia for 2 years. Based on the results of thyroid hormone, resistance to thyroid hormone (RTH) was suspected. Physical examination during hospitalization revealed a palpable upper abdominal mass. Several diagnostic examinations were performed. The abdominal ultrasound showed acoustic shadowing caused by a pathological structure in the upper abdomen. Therefore, the contrast X-ray of the digestive tract revealed a deficit of contrast with an irregular shape in the stomach body and the pylorus region. Due to these results, a gastroscopy was performed, which revealed a large trichobezoar of the stomach. The trichobezoar was surgically removed without complications. Conclusion: The case presented shows that these nonspecific symptoms and laboratory test suggesting RTH require multi-path diagnostics and the cooperation of many specialists, ultimately giving a surprising diagnosis. It is crucial to interpret diagnostic examinations with regard to the patient's physical condition. Diagnosis of trichobezoar requires a detailed search of causes to avoid another incident.

Verification of the Perception of the Local Community concerning Air Quality Using ADMS-Roads Modeling.

Road transport is one among the sources of air pollution in a city, which results in lowering the comfort of life and increases the occurrence of respiratory diseases. The level of pollutants emitted in the city is variable, and it depends on the type and nature of the source and the manner of land development. For this reason, the purpose of the article is an attempt at a spatial (inner) diversification of a city in terms of air quality, using a study of perception and semantic differentials (SD). The research, which covered the period from June to November 2021, was performed in Kielce-the Polish Smart City-among local experts, people well acquainted with the city and knowledgeable about air quality and the impact of pollution on human health. The results allowed the demarcation of areas with the best and the worst parameters in terms of air quality within the city. Verification of the survey was carried out using the ADMS-Roads (Atmospheric Dispersion Modeling System) software for modeling pollution levels and GIS software, using data on road traffic. The verification allowed checking whether the respondents participating in the research accurately evaluated the city space. The modeling proved that within the two selected areas, the pollution level is similar, and it does not exceed the permitted values. This might indicate that in society there is still low awareness of air quality, particularly in terms of knowing the sources of pollutants and their impact on human health, and perception of areas with the best and the worst air quality was the result of an analysis of the manner of land development and its morphology.
