Sexual dimorphism of dynamics of concentration of endothelium alteration factors in blood in surgical treatment of chronic generalized periodontitis.

Summary:

Aim: to study the sexual dimorphism of the concentration in the blood of endothelial alteration factors in the dynamics of the surgical treatment of moderate chronic generalized periodontitis (CGP) in comparison with clinically healthy volunteers. Material and Methods. A total of 20 clinically healthy volunteers (average age is 30 (24; 37), 50% are men) and 31 patients with moderate chronic generalized periodontitis (average age is 31 (27; 38), 40% are men) were examined. Serum concentrations of homocysteine and C-reactive protein were determined. Patients with chronic generalized periodontitis were treated following the surgical scheme. Results. In patients with chronic generalized periodontitis, prior to treatment, an increased level of homocysteine and C-reactive protein (CRP) was detected in the serum. Conservative treatment in the preoperative period caused a decrease in the level of homocysteine in patients, while there was no significant change in the rate of C-reactive protein. 10 days after the surgery, an increase in the concentration of homocysteine and C-reactive protein in serum was observed in patients of both sexes, indicating a reactive change. At the same time, reactive changes were more pronounced in women. Long-term results of surgical treatment of chronic generalized periodontitis indicate a decrease in C-reactive protein and homocysteine levels in patients of both sexes. Sexual dimorphism was manifested by the fact that women had lower homocysteine content than men: 9.4 (8.9; 9.7) versus 13.3 (10.8; 14.1) umol/l (p=0,004). Conclusion. Patients of both sexes with moderate chronic generalized periodontitis have elevated C-reactive protein and homocysteine levels. Sexual dimorphism is manifested by higher levels of homocysteine, but not C- reactive protein in men. The acute period of surgical treatment of chronic generalized periodontitis is characterized by an increase in the concentration of factors affecting the endothelium in the blood, which are more pronounced in women. Long-term surgical treatment results of chronic generalized periodontitis demonstrate a decrease of homocysteine and C-reactive protein levels in blood with homocysteine levels being lower in women than in men.

Professor I.Ya. Livshits and his contribution to the development of national neurosurgery

Summary:

The article traces the professional path of Professor Lev Yakovlevich Livshits, assesses his scientific contribution to the development of national neurosurgery. The concept of minimally invasive surgical treatment of trigeminal nerve neuralgia, developed by L. Ya. Livshits, allowed developing an original method of puncture surgical treatment of pain syndrome by directed hydrothermal destruction of the sensitive trigeminal root. The concept of "growing radicalism" created by Professor L. Ya. Livshits allowed his students elaborating algorithms for treating severe chronic pain syndromes of any localization and etiology.
