AbstractBackground/Aim. Early diagnosis and adequate surgical treatment are the key factors for the course of the laryngeal cancer of the head and neck and the outcome of the surgical treatment in these patients. The aim of the paper is to compare the characteristics of the surgically treated patients with the larynx carcinoma who developed recidivism to those who did not.Material and methods. The study was done as a retrospective observational case-control study on a total of 90 patients with the laryngeal cancer who had been successfully operated on and whose cases had been followed over a period of at least five years after the surgery. After that, they were shorted into two groups based on the development of recidivism, and clinical characteristics of the patients with and without recidive disease were compared.Results. 19 out of 90 patients developed recidivism. Maximum diameter of the tumour was significantly larger in patients without local recidivism. In patients without local recidivism, most common clinical stages were 3 and 4 (32.4%, 40.8%, respectively), whereas in patients with local recidivism stages 1 and 2 were the most common (47.7%, 26.3%, respectively). The average time to disease recurrence in the 19 patients who developed local recidive disease was 648.10 (384.67-911.54) days.Conclusion. Pathohisto-logical analysis showed that samller the size of the tumour and lower T grade at the moment of surgery are precautionary factors for further monitoring of patients with laryngeal cancer.

Squamous cell carcinoma of the larynx is a multifactorial disease. It is firmly linked to several environmental risk factors. In the meanwhile, a considerable amount of epidemiologic evidence has been built up to implicate chronic consumption of alcohol and tobacco, occupation, diet, and social status in the etiology of the laryngeal cancer. Herein is a report from the first case-control study on the role of these risk factors conducted in a German population of patients with laryngeal cancer.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease (COVID-19), a highly contagious infectious disease that has caused many deaths worldwide. Despite global efforts, it continues to cause great losses, and leaving multiple unknowns that we must resolve in order to face the pandemic more effectively. One of the questions that has arisen recently is what happens, after recovering from COVID-19. For this reason, the objective of this study is to identify the risk of presenting persistent symptoms in recovered from COVID-19. This case-control study was conducted in one state of Mexico. Initially the data were obtained from the participants, through a questionnaire about symptoms that they had at the moment of the interview. Initially were captured the collected data, to make a dataset. After the pre-processed using the R project tool to eliminate outliers or missing data. Obtained finally a total of 219 participants, 141 recovered and 78 controls. It was used confidence level of 90% and a margin of error of 7%. From results it was obtained that all symptoms have an associated risk in those recovered. The relative risk of the selected symptoms in the recovered patients goes from 3 to 22 times, being infinite for the case of dyspnea, due to the fact that there is no control that presents this symptom at the moment of the interview, followed by the nausea and the anosmia with a RR of 8.5. Therefore, public health strategies must be rethought, to treat or rehabilitate, avoiding chronic problems in patients recovered from COVID-19.
