[Receptive status of the endometrium in patients with benign ovarian tumors before and after organ-preserving operations]. / Retseptivnyi status endometriya pri dobrokachestvennykh opukholyakh yaichnikov do i posle organosokhranyayushchikh operatsii.

Background. Benign ovarian tumors (BOT) occupy the 2nd place in the structure of diseases of the female genital organs. In 20% of women of reproductive age, BOT are associated with infertility. One of the causes of infertility caused by ovarian tumors is morphofunctional inferiority with impaired endometrial receptivity. OBJECTIVE: To reveal the morphological and functional features of the endometrium and the level of receptivity to sex hormones in patients with BOT before and after organ-preserving operations. MATERIAL AND METHODS: The study included 77 patients with epithelial ovarian tumors (EOT) - I group, 52 with mature teratomas (MT) - II group. Before and 6-12 months after laparoscopic cystectomy aspiration biopsy of endometrium was performed in the middle stage of secretory phase. The percentage and degree of maturity of pinopodes were determined, and the level of expression of estrogen (ER) and progesterone (PR) receptors in the glands and stroma of the endometrium was assessed. RESULTS: At the preoperative stage, a decrease in the number of mature pinopodes in patients with EOT was revealed. Normal levels of ER were determined in glands and stroma of endometrium, PR was reduced both in stroma and glands of uterine mucosa. In patients with MT all markers corresponded to those of healthy women. In the postoperative period an increase in the number of developed pinopodes on the apical surface of endometrium in patients of I group was found. The ER level did not differ from control values, PR remained reduced in stroma. In II group a persistent decrease in quantity of mature pinopodes, ER in stroma, PR in glands and stroma of uterine mucosa was recorded. CONCLUSION: The presence of BOT and unintentional intraoperative removal of healthy ovarian tissue lead to indirect disorders of the morphofunctional state and endometrial receptivity.

[The early diagnosis of congenital neuroinfections during ophthalmologic examination in children of the first months of life]. / Rannyaya diagnostika nekotorykh vrozhdennykh neiroinfektsii pri oftal'mologicheskom osmotre u detei pervykh mesyatsev zhizni.

OBJECTIVE: To characterize the possibilities of early diagnosis of congenital neuroinfections during an ophthalmological examination in children in the first months of life. MATERIAL AND METHODS: Five children with congenital neuroinfection, including 2 children with congenital toxoplasmosis and 3 children with congenital cytomegalovirus infection (CMVI), were studied. All babies were born prematurely (25 to 31 weeks of gestation (27.2±0.94)), with birth weight from 680 to 1610 g (1120±110.1). During the examination, binocular ophthalmoscopy and examination on a wide-field retinal pediatric camera were used. A blood testing for immunoglobulins and a polymerase chain reaction of blood were performed. To assess the state of the brain, neurosonography and magnetic resonance imaging were used. RESULTS AND CONCLUSION: Ophthalmic signs of intrauterine infection appeared at the age of 4-5 months (at 47-51 weeks of postmenstrual age). In all children (in 4 in one eye, in 1 in both eyes), apparent exudative-proliferative changes in the retina and vitreous body appeared on the periphery with the formation of epiretinal membranes that exert a traction effect on the retina. In two children with CMVI, multiple preretinal hemorrhages in different parts of the retina in both eyes were revealed. Central chorioretinal foci in the fundus were detected in children with toxoplasmosis. A positive dynamics, such as a decrease of exudative phenomena, a partial fit of the retina, complete resorption of hemorrhages, was noted in children during treatment. It has been concluded that signs of intrauterine neuroinfection can appear delayed, only by the development of chorioretinitis, 4-5 months after birth and manifest with severe exudative-proliferative changes in the retina and vitreous body.
