Jaw Defects

Cancer of the lower jaw is one of the most common causes of the development of total defects. There are many indices and indicators to assess the quality of life of patients with this pathology, but they do not fully describe the features of their postoperative rehabilitation. The question of developing an evaluation criterion for the introduction of a special device in patients with subtotal defects of the lower jaw remains open.Material and methods. In the period from 2010 to 2021, 100 patients with subtotal defects of the lower jaw, aged 30 to 65 years old, who are being treated in the Department of Maxillofacial Surgery at the Department of Maxillofacial Surgery of the GBUZ SKKKB, were interviewed. All patients were divided into 2 groups of 50 people each. In the main rehabilitation was carried out using a special device to optimize the biomechanics of the lower jaw, in the control group, rehabilitation was carried out without one. The article presents the results of assessing the quality of life, which were carried out using a special questionnaire.Conclusions. This questionnaire makes it possible to assess the standard of living of patients using a special device at the stages of rehabilitation.

Abstract Surface deposits and sediment cores were collected from the Upper Bonny Estuary, located in Southwest Nigeria, and analyzed to determine spatio-temporal and vertical distributions of radio-nuclide activities expressed in Bq·kg−1 dry weight. The results of activities of naturally occurring radionuclides of 226Ra (15 ± 2–34 ± 3 Bq·kg−1), 228Ra (32 ± 5–48 ± 6 Bq·kg−1), 40K (264 ± 29–462 ± 36 Bq·kg−1) were found to be all within the range of typical values reported for coastal regions. Ratios of 226Ra to 228Ra suggested accretion for all samples with low sediment accumulation registered during rainy months. In addition, vertical distributions at the three sampling sites were also studied with the initial aim of establishing chronologies from the decay of excess 210Pb. In two cores, excess 210Pb, estimated by subtracting 226Ra from total 210Pb on a layer-by-layer basis, exhibit relatively constant activity with discrete minima and maxima. Therefore, these cores were excluded from radiometric dating. Only the third core could be dated by the constant rate of supply model, and 137Cs was utilized to validate the 210Pb chronology.

137Cs Contamination

By gamma spectroscopic measurement a content of natural radio-nuclides (40K, 238U, 226Ra, 232Th) and 137Cs was determined in samples of soil, alfalfa, maize and moss on six sites in the surroundings of Belgrade. Natural radionuclides in the soil were at the level characteristic for Serbia, whereas a relatively high level of activity of 137Cs (around 30 Bq kg-1) was determined. On the other hand, in plant samples mostly used as feed (such as alfalfa and maize) the concentration of natural radio-nuclide activity and 137Cs was relatively low, i.e. below the range of detection. The content of natural radio-nuclides in moss was within the standard range of values specific for Serbia. However, the activity level of 137Cs in moss gathered from the wider area around Belgrade, was high, the highest measured level being in the Avala-Zuce area (158-221 Bq kg-1). Our results show that this radio-nuclide is still present in the living environment of Belgrade even 20 years after the Chernobyl disaster, and that moss is a good indicator of living environment 137Cs contamination.
