Dose Radiation

A case of chronic, fluctuating plasma cell gingivostomatitis that progressed despite chemotherapy and surgery is reported. This is the first case reported of treatment with radiation therapy, and one of the few cases reported where the infiltrate has reached the larynx. After receiving low dose radiation therapy, via a conformal technique encompassing the respiratory mucosal lining from the base of tongue to carina, there has been symptomatic improvement.

Clustering Problems

In this paper, we present efficient geometric algorithms for the discrete constrained 1-D K-means clustering problem and extend our solutions to the continuous version of the problem. One key clustering constraint we consider is that the maximum difference in each cluster cannot be larger than a given threshold. These constrained 1-D K-means clustering problems appear in various applications, especially in intensity-modulated radiation therapy (IMRT). Our algorithms improve the efficiency and accuracy of the heuristic approaches used in clinical IMRT treatment planning.

Radiolabeled Antibodies

The use of low-dose radiation therapy (LDRT) in patients with pneumonia from 1905 to 1943 provided positive results in 83.08 % of cases. Interest in LDRT is supported by researchers of radiation hormesis in the 21st century. Attention is drawn to the dynamics of coronavirus infection in the regions of Ukraine and the Kirovograd region with a minimum incidence. It is known that 95 % of uranium ore deposits in Ukraine are concentrated in the Kirovograd region. The positive experience of LDRT in Iran, India, USA, Spain for the treatment of patients with COVID-19 is described. LDRT (<100 cGy) is known to be anti-inflammatory, and therefore pulmonary LDRT has the potential to reduce the severity of pneumonia and reduce mortality. LDRT deserves a clinical study. A new direction in radiation therapy – Auger therapy based on radiolabeled antibodies – is planned to be used as a molecular targeting radiotherapy agent directly to the SARS-CoV-2.
