Résumé
SUMMARY: Hypersensitivity reactions has been reported with COVID-19 vaccines. Acute eosinophilic pneumonia has not been reported yet after Sinovac/CoronaVac vaccine. A 73-year-old woman presented with maculopapular rash, cough and dyspnea following Sinovac/CoronaVac injection. The complete blood count (CBC) indicated eosinophilia and further evaluation of the eosinophilia with CT and bronchoscopy confirmed a diagnosis of acute eosinophilic pneumonia. After methylprednisolone therapy, her rash resolved with marked improvement of the dyspnea. She is still on treatment and on the follow up period, we plan to continue steroid treatment at least 3 months.
Résumé
Objective: The coronavirus disease-2019 (COVID-19) pandemic has caused delays in the diagnosis and treatment of some oncological diseases. This study aimed to reveal the effect of the COVID-19 pandemic on the frequency of diagnosis of non-melanoma skin cancers (NMSC) and the demographic characteristics of patients. Material and Methods: Patients aged over 18 years, who were histopathologically diagnosed with basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) between March 12, 2019 and March 11, 2021 were included in the study. The demographic characteristics of these patients, the number of total skin biopsies, and the number of BCC and SCC biopsies were compared between the pre-pandemic and pandemic periods, based on the date of March 12, 2020, when the pandemic measures began to be implemented in Turkey. Results: With the pandemic, there was a 26.7% decrease in the total skin biopsies and a 21% decrease in the total NMSC biopsies. Despite a 34% decrease in the number of biopsies for the diagnosis of BCC, a 15.8% increase was observed in the number of biopsies for the diagnosis of SCC. The frequency of excisional biopsies was observed to increase among the patients with BCC and SCC during the pandemic period (p=0.004 and p=0.001, respectively). Conclusion: The number of total skin biopsies and total NMSC biopsies significantly decreased during the pandemic period. The health system should be reorganized to effectively handle pandemics and similar crisis periods, and new strategies should be determined regarding patient education, early diagnosis, and treatment approaches for NMSC.
Résumé
Biotechnology co-progresses along the continuous development within other technologies and science fields such as nanophysics, thermodynamics etc. Their developments had an equal contribution to PCR devices, one way or another new innovations end up being integrated within them such as different thermal cyclings or sensors used to identify fluorescent dyes. With the global 2020 pandemic, biotechnological advances quickly became a hot-topic globally and PCR marketing skyrocketed due to an increase of demands. With a rise in positive SARS-CoV-2 cases, laboratories sought more lightweight and portable devices that are less expensive but high-sensitive props and kits to work their tests with. Microchips’ involvement within the PCR markets achieved just that, and has proven to be revolutionary. What these chips and their accompanying hardware properties within PCR devices provide, their types and in what areas some specific chips such as photodiodes suit best are all explained in this review along with crediting the first origins of PCR devices.
