Case report: Spontaneous rupture of leiomyosarcoma uteri 8 months after primary laparoscopic surgery of STUMP.

Introduction: Leiomyosarcoma (LMS), together with smooth muscle tumors of uncertain malignant potential (STUMP) and benign leiomyomas, belongs to a heterogeneous group of uterine neoplasms. According to the World Health Organization, tumors originating from uterine smooth muscle fibers are the second most frequent tumors. It is challenging to distinguish between STUMP and LMS because of an overlap of symptoms, lack of a precise definition, and unequivocal information obtained using imaging diagnostic methods. Following myomectomy or hysterectomy with laparoscopic or laparotomy surgery and a definitive histological diagnosis of STUMP, the course of treatment is determined by the need to preserve fertility. In 2014, the U.S. Food and Drug Administration published an alert that unprotected laparoscopic morcellation is correlated with a 3-fold higher likelihood of dissemination of malignant cells and disease progression. Unprotected morcellation was independently associated with a higher risk of disease recurrence after demolition or conservative surgery, with a relative risk of 2.94. Conclusion: Hematoperitoneum resulting from the spontaneous rupture of a uterine tumor is a rare gynecological emergency, with very few cases reported in the last decade.

Green Extraction Strategy Using Bio-Based Aqueous Biphasic Systems for Polyphenol Valorization from Grape By-Product.

Polyphenols are natural compounds with enhanced antioxidant properties. They are present in relatively high concentrations in fruit/vegetable by-products. Therefore, there is a need for the development of efficient and cost-effective methods for the separation and purification of these valuable compounds. Traditional extraction with organic solvents needs to be switched to novel methods that are more efficient, with reduced extraction times and low consumption of organic solvents. Aiming at developing sustainable processes for the separation and purification of phenolic compounds, we used three model compounds, namely resveratrol, quercetin, and gallic acid, to investigate ionic liquid-based aqueous biphasic systems (IL-ABSs) formed by cholinium-based IL in combination with polypropylene glycol with a molecular mass of 400 g/mol (PPG400). The ABS composition in the two-phase region was selected according to a previously determined phase diagram. Extraction studies indicated the preferential partition of resveratrol and quercetin toward the hydrophobic PPG-rich phase that is mainly dominated by its hydrophobic nature and the strong salting-out effect of ILs. On the other hand, due to its considerably hydrophilic nature, gallic acid preferentially migrates toward the IL phase. The achieved results from grape stem extract demonstrated high extraction efficiencies of cholinium dihydrogen phosphate (~99% for resveratrol for the PPG phase and 78% for gallic acid for the IL phase), with considerable selectivity, demonstrating promising outcomes for potential applications.

Prognostic Value of Lactate Dehydrogenase in Patients with Melanoma Treated with Pembrolizumab.

INTRODUCTION: Elevated LDH levels have been extensively reported as a biomarker of poorer outcome in patients with melanoma during the chemotherapeutic era. The role of LDH level as a prognostic factor for treatment outcomes in patients with metastatic melanoma treated with immunooncological therapy has also been reported but requires further analysis. OBJECTIVES: In this study, we aimed to evaluate the prognostic value of lactate dehydrogenase (LDH) among patients with metastatic and unresectable melanoma treated with pembrolizumab in terms of progression-free survival (PFS). METHODS: The study included 59 patients with unresectable and metastatic melanoma treated with pembrolizumab. A comparison was performed between patients with normal and elevated levels of LDH in terms of PFS, with subgroup analysis. RESULTS: There was a significant reduction in PFS among patients with elevated levels of LDH compared with patients with normal levels of LDH (NR vs. 5 months; P=0.02). Patients with elevated LDH levels were older (P=0.01), with liver metastasis (P=0.004), and with less frequent CNS deposits (P=0.028). CONCLUSION: Although novel agents improved outcomes in patients with melanoma, high levels of LDH persist as an independent prognostic biomarker of poor prognosis.

Five-year disease-free survival in FIGO IA stage endometrial cancer patients: Tertiary institution experience in a developing country.

Purpose: Endometrial cancer is characterized as histopathological, molecular, genetic, biological, and very diverse group of malignancies. Due to the need to precisely define the indications for adjuvant treatment in recent years, there has been a division made according to risk groups based on prognostic factors, which identify patients at risk for disease relapse, who may benefit from adjuvant therapy. The aim of this research was to examine the clinical and morphological factors that influence disease-free survival (DFS) and overall survival (OS) in patients with FIGO IA stage endometrial cancer. Material and methods: A retrospective clinical study was conducted, primarily based on the identification of factors that influence five-year DFS and OS. The study integrated data of FIGO IA stage endometrial cancer patients, who presented to gynecological oncology board for the first time after operative treatment, from January 1, 2016 to January 1, 2022. Adjuvant radiotherapy was applied to patients with an initially higher risk of disease progression. Length of survival was analyzed using Kaplan-Meier method, while log-rank test was used to assess differences between groups. Results: The results show that 5-year OS for 93 patients was 89.2% and DFS was 88.2%. Application of adjuvant brachytherapy, number of deliveries, MRI staging, type of institution where the surgery was performed influenced DFS. Pathohistological characteristics of tumor indicated a statistically significant impact on DFS. Conclusions: Application of adjuvant brachytherapy in high-intermediate and high-risk patients contributes to DFS increase. Moreover, the existence of a pre-operative MRI assessment of the stage of disease as well as the type of healthcare provided by an institution where the surgery was performed, significantly affect DFS.

Psychological Distress in Women With Abnormal Pap Smear Results Attending Cervical Cancer Screening.

OBJECTIVE: Women often experience psychological distress upon receipt of an abnormal Pap test result. This study aimed to evaluate psychological distress and its correlates among women who received an abnormal Pap screening test result. MATERIAL AND METHODS: A cross-sectional study was performed in a cohort of 172 consecutive women who had attended screening for cervical cancer and who received abnormal Pap smear results and underwent additional diagnostic procedures (colposcopy/biopsy/endocervical curettage). The participants filled out a questionnaire on sociodemographic variables and the Cervical Dysplasia Distress Questionnaire. Multivariate linear regression was used for the analysis of the data. For multiple comparisons, the Bonferroni correction was applied to adjust the level of significance. RESULTS: In women who received an abnormal Pap smear result, the independent correlate of higher psychological distress (by Cervical Dysplasia Distress Questionnaire score) before diagnostic procedures was lower satisfaction with information/support received from other people ( p = .002). Correlates of psychological distress in women older than 40 years with abnormal Pap smear were anxiety ( p = .042) and worry about having cervical cancer, general health and having sex ( p = .044). CONCLUSIONS: The authors' findings could enable control of factors predictive of psychological distress in women who received a positive Pap smear screening test before undergoing diagnostic procedures, primarily via active provision of targeted information.

High Fat Diet Exaggerate Metabolic and Reproductive PCOS Features by Promoting Oxidative Stress: An Improved EV Model in Rats.

Background and Objectives: Polycystic ovary syndrome (PCOS) is a frequent multifactorial endocrinopathy affecting women in the reproductive period, often associated with infertility and metabolic disorders. The use of animal models helps to better understand etiopathogenesis, enabling the examination of the effects of certain drugs in order to discover the best possible therapeutic approach. We tried to investigate the additional effect of estradiol-valerate (EV) and high-fat diet (HFD) in female rats to explore PCOS-related alterations with special focus on oxidative stress. Materials and Methods: Animals were divided into three groups: control group (CTRL, n = 6), estradiol-valerate group (EV, n = 6), and estradiol-valerate group on HFD (EV + HFD, n = 6). PCOS was induced by single subcutaneous injection of long-acting EV in a dose of 4 mg/per rat. We tried to improve the metabolic characteristics of the PCOS animal model by adding HFD, so the CTRL and EV group had a regular diet, while the EV + HFD group had HFD during the induction period of 60 days. Results: We observed alterations of anthropometric parameters and hormonal disturbances, along with estrus cycle impairment reassembly to obese-type PCOS phenotype. Moreover, glucose metabolism was impaired after addition of HFD to EV protocol, contrary to EV administered alone. Histological analysis confirmed more numerous cystic follicles after the combination of EV and HFD protocol. The alterations of oxidative stress markers could be related to and serve as the mechanistic base for development of PCOS-related endocrine, reproductive, and metabolic properties. Conclusions: The additive effect of EV and HFD was obvious in the majority of the parameters observed. Our study strongly demonstrated metabolic as well as reproductive properties of PCOS in rats.

Predictors of Anxiety Before and After Diagnostic Procedures in Women with Abnormal Papanicolaou Smear in Cervical Cancer Screening Program.

Anxiety is one of the most common causes of withdrawal from follow-up among women with abnormal Papanicolaou screening results. The purpose of this study was to investigate predictors of anxiety in women with abnormal Papanicolaou smear in cervical cancer screening program. A population-based, cross-sectional study concerning the factors related to anxiety was carried out during 2017 in a cohort of women (N = 172) with positive Papanicolaou screening test before and after diagnostic procedures (colposcopy/biopsy/endocervical curettage) at one university Clinical Center in Serbia. Women completed a socio-demographic questionnaire and scale concerning anxiety (Hospital Anxiety and Depression Scale, subscale HADS-Anxiety) immediately before and 2-4 weeks after the diagnostic procedures. Multivariate logistic regression was applied in the data analysis. In our study, 35.2% (n = 52) of women had abnormal anxiety scores before the diagnostic procedures and 40.1% (n = 69) after the diagnostic procedures. Predictors of anxiety before diagnostic procedures were family history of noncervical gynecological cancers, higher level of worry and high burden of depressive symptoms. Significant independent predictors of anxiety after diagnostic procedures in women were rural residence, tension and discomfort during medical procedures, and less satisfaction with information/support. Although there was no significant difference in the prevalence of anxiety before and after diagnostic procedures in women with abnormal Papanicolaou screening results, results of this research will enable doctors to successfully make decisions concerning timely psychological support for women with positive screening test for cervical cancer that is necessary to decrease anxiety in our population.

Predictors of depressive symptoms before and after diagnostic procedures in women with abnormal Pap smear attending cervical cancer screening programme in Serbia.

OBJECTIVES: Receipt of a positive Papanicolaou screening result and subsequent referral for diagnostic tests can cause psychological stress. Still, not enough is known about depression before and after the diagnostic test in these women. The aim of this study was to determine the burden and predictors of depressive symptoms prior to and after diagnostic investigations in women who had received a positive Papanicolaou screening result. METHODS: This was a cross-sectional study. Study cohort comprised women who received an abnormal Papanicolaou screening result. Women completed the socio-demographic questionnaire and 'The Center for Epidemiologic Studies Depression, CES-D' questionnaire before and after diagnostic tests (colposcopy/biopsy/endocervical curettage) to assess factors related to depression. RESULTS: No significant difference was noted in the frequency of depressive symptoms (CES-D score ≥ 16) before and after diagnostic investigations, but the mean score on CES-D scale showed a significant difference before and after diagnostic investigations (13.98 ± 9.56 and 12.74 ± 9.15, respectively). A significant predictor of depression before diagnostic investigations was spontaneous abortion, whereas family history of other gynaecological cancers was a predictor of depression after diagnostic investigations. CONCLUSIONS: Our findings could contribute to improving the rates of cervical cancer screening, by identifying women at risk for depression before and after investigations.

Bevacizumab with Chemotherapy as a First-Line Treatment for Advanced Ovarian Cancer in a Serbian Cohort.

Background and Objectives: For stage IIIb-IV ovarian cancer, bevacizumab-containing treatment is considered the standard of care. The purpose of this study was to evaluate the efficacy of bevacizumab in combination with carboplatin and paclitaxel as a first-line treatment for advanced ovarian cancer. Materials and Methods: Eligible patients had stage IIIc-IV ovarian cancer according to the International Federation of Gynecology and Obstetrics with no clinical signs or symptoms of gastrointestinal obstruction or a history of abdominal fistulae, gastrointestinal perforation, or intra-abdominal abscess or evidence of rectosigmoid involvement by pelvic examination, bowel involvement on computed tomography, or clinical symptoms of bowel obstruction in the previous 6 months. After debulking surgery, the patients received 175 mg/m2 paclitaxel and carboplatin (AUC 6) for the first six cycles and 7.5 mg/kg bevacizumab every three weeks up to 17 cycles until disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was progression-free survival. The secondary endpoint was overall survival. Results: Between April 2017 and March 2020, 35 patients began study treatment. Bevacizumab was administered at 7.5 mg/kg in all the patients and for more than 7.5 months in 70% of them. The median progression-free survival was 20 months (95% CI: 16-23). The median overall survival was not reached. Conclusions: This was, to our knowledge, the first trial in Serbia to show progression-free survival and overall survival of combination regimens in advanced ovarian cancer. Based on the observed progression-free survival, bevacizumab combined with chemotherapy should be considered as a standard option in advanced ovarian cancer.

Potential role of d-chiro-inositol in reducing oxidative stress in the blood of nonobese women with polycystic ovary syndrome.

d-chiro-Inositol (DCI), an isomer of inositol, possesses antioxidative and endothelial protective properties. Possibly due to a deficiency of insulin mediators, polycystic ovary syndrome (PCOS) is often associated with insulin resistance (IR) and hyperinsulinemia, likely responsible for an elevated production of reactive oxygen species. We investigated oxidative-related alterations of inositol in the blood of women with PCOS before and after treatment with DCI. A total of 38 normal-weight PCOS women were investigated before and after DCI administration (500 mg/day for 12 weeks; n = 38) by evaluating serum testosterone, serum androstenedione, fasting serum insulin, fasting serum glucose, and parameters of IR. From the blood, we determined biomarkers of oxidative stress: superoxide anion radicals, hydrogen peroxide, nitric oxide, and the index of lipid peroxidation. The activity of catalase and superoxide dismutase and the reduced glutathione (GSH) content in the hemolysate were also assessed. Data showed that PCOS patients' plasma underwent oxidative stress, as indicated by the higher level of prooxidants and reduced cytosolic GSH content. DCI treatment significantly improved the metabolic parameters. Also, serum values of testosterone were reduced. In conclusion, PCOS patients suffer from a systemic oxidative stress that induces endothelial dysfunction. Treatment with DCI is effective in reducing hormonal, metabolic, and oxidative abnormalities in PCOS patients by improving IR.

Depression before and after diagnostic procedures among women with abnormal finding of Papanicolaou screening test.

BACKGROUND: Some studies did find significant differences in the level of depression of women while undergoing diagnostic evaluation of an abnormal Papanicolaou screening smear, but findings were not consistent. This study aimed to assess prevalence and correlates of depression in women with abnormal cervical screening results before and after diagnostic procedures. METHODS: A cross-sectional study was carried out during 2017 in a cohort of women with positive Papanicolaou screening test before and after diagnostic procedures (colposcopy/biopsy/endocervical curettage) at the university Clinical Centre Kragujevac, Serbia. Women completed a questionnaire about demographics, lifestyle, and other factors of interest. Also, questionnaire "Hospital Anxiety and Depression Scale" (HADS) was used immediately before and 2-4 weeks after the diagnostic procedures: a score of ≥8 on HADS-D and HADS-A subscales indicated depression and anxiety, respectively. Multivariate logistic regression was applied in the data analysis. RESULTS: The study comprised 172 women, giving a response rate of 72.3%. The mean age of the participants was 47.8 ± 11.1 years (range 23-65). The frequency of depressive symptoms was significantly higher after diagnostic procedures (48.3%) than before diagnostic procedures (37.2%) (p = 0.038). Before diagnostic procedures, older age (OR = 1.60; 95% CI = 1.09-2.34; p = 0.017), and level of anxiety according to the HADS-A subscale (OR = 1.61; 95% CI = 1.38-1.88; p < 0.001) were significant independent predictors of depression. After diagnostic procedures, significant independent predictors of depression were urban place of residence (OR = 0.12; 95% CI = 0.03-0.47; p = 0.002) and level of anxiety according to the HADS-A subscale (OR = 1.85; 95% CI = 1.54-2.21; p < 0.001). CONCLUSION: Our study showed that older age, rural residence, and anxiety play a role in shaping the risk of depression among women undergoing additional diagnostic procedures after receiving an abnormal Papanicolaou screening result.

Internal consistency and validity of the Hospital Anxiety and Depression Scale (HADS) in women with abnormal Pap smear in Serbia.

Receiving a report of an abnormal finding of Pap screening test in women often leads to anxiety and depression. The purpose of this study was to investigate the construct validity and internal consistency reliability of the Serbian version of the Hospital Anxiety and Depression Scale (HADS) in women with abnormal Pap smear results. In 2017, a cross-sectional study was done involving 142 consecutive women attending cervical cancer screening who had received abnormal Pap smear results at one University clinical center in Serbia. We used exploratory factor analysis to establish the structure of the HADS and Cronbach's alpha coefficient was used for assessing the internal consistency. In our study, the HADS demonstrated high internal consistency, for both subscales (Cronbach's alpha coefficient for subscale Anxiety was 0.862, and for subscale Depression was 0.851). The intra-class correlation coefficients for the two components were significant (0.860 and 0.843, p < .001). Principal component analysis with Oblimin rotation indicated a two-factor structure that explained 56.4% of variance. In conclusion, the Serbian version of the HADS showed satisfactory internal consistency reliability and construct validity and could be useful as a screening questionnaire for the assessment of anxiety and depression among women with abnormal Pap smear results.

Effects of selective serotonin reuptake inhibitors on motility of isolated fallopian tube.

Selective serotonin reuptake inhibitors (SSRIs) affect the smooth muscle cells acting on voltage-dependent channels for Na+ , K+ and Ca2+ , but their action is tissue and species specific. The aim of our study was to investigate effects of selective serotonin reuptake inhibitors on motility of the isolated fallopian tubes. Isolated preparations of isthmus and ampoule were taken from fallopian tubes of 20 women during hysterectomy due to uterine fibroids and then tested for reactivity on increasing concentrations of selective serotonin reuptake inhibitors. Escitalopram (from 0.9 × 10-9  M/L to 1.4 × 10-6  M/L) produced concentration-dependent increase of spontaneous contractions of the isolated ampulla (EC50 = 1.20 ± 1.06 × 10-8  M/L, r = 0.580, P < 0.05) (F = 2.980, df1  = 6, df2  = 28, P < 0.05). Paroxetine (from 1.2 × 10-9  M/L to 5.1 × 10-5  M/L) produced concentration-dependent increase of spontaneous contractions of the isolated isthmus (EC50 = 7.01 ± 3.50 × 10-8  M/L, r = 0.500, P < 0.05) (F = 2.350, df1  = 9, df2  = 40, P < 0.05). The SSRIs differ among themselves in regard to their potential to affect motility of the fallopian tubes. Escitalopram and paroxetine have clear stimulating effect which may interfere with functioning of the fallopian tubes, and potentially impair fertility if taken by women in reproductive period of life. The other SSRIs tested in the study did not produce significant effect throughout the concentration range used in the experiments.

Reliability and validity of the Center for Epidemiologic Studies Depression (CES-D) scale in Serbian women with abnormal Papanicolaou smear results.

OBJECTIVES: Cervical cancer ranks as the second most frequent cancer among women in Serbia. Organized screening for detection of cervical cancer was introduced in Serbia in 2013 and provided free of charge in all state health facilities. Studies have shown that depression frequently follows the notification of abnormal findings on the Papanicolaou (Pap) screening test. The aim of this study was to examine the reliability and validity of the Center for Epidemiologic Studies Depression (CES-D) scale among women in Serbia receiving a report of abnormal cytology. METHODS: This population-based study used cross-sectional, self-reported data involving 198 consecutive women attending cervical cancer screening who had received abnormal Pap smear results. All participants completed the socio-demographic questionnaire and CES-D scale. Reliability of the CES-D scale was assessed by internal consistency reliability (measured with standardized Cronbach's coefficient α). Exploratory factor analysis was done using Promax rotation. RESULTS: The overall Cronbach's α coefficient of the CES-D scale was 0.865, while the Cronbach's α coefficients for the subscales Depressed affect, Somatic complaints, Positive affect, and Interpersonal relationship were 0.885, 0.802, 0.851, and 0.593, respectively. Principal component analysis with Oblimin rotation indicated four main components that explained 62.0% of variance. Over one-quarter (28.8%) of the participants scored above the cut point (≥16) on the CES-D scale. The mean score for depressive symptoms was 13.0 for the study sample. CONCLUSIONS: The Serbian version of the CES-D scale proved to be a valid and reliable instrument for identifying patients with depressive symptoms among women with abnormal Pap smear results.

Psychological distress among women with abnormal pap smear results in Serbia: Validity and reliability of the Cervical Dysplasia Distress Questionnaire.

BACKGROUND: Receiving report of an abnormal finding from a Pap screening test in women often leads to psychological distress. OBJECTIVES: The purpose of this study was to assess the reliability and validity of the Cervical Dysplasia Distress Questionnaire (CDDQ) among women in Serbia. METHODS: In 2017, we conducted a cross-sectional study involving 154 consecutive women attending cervical cancer screening who had received abnormal Pap smear results. RESULTS: Reliability assessment showed good internal consistency for all CDDQ subscales (Tension and discomfort: Cronbach's α = 0.844; Embarrassment: α = 0.864; Sexual and reproductive consequences: α = 0.867; and Health consequences: α = 0.913). The test-retest reliability showed that the correlation coefficients (between 0.805 and 0.983) were significant at the 0.01 level for all of the Serbian CDDQ subscales. Principal Axis Factoring with Direct Oblimin rotation indicated four main components that explain 55.0% of variance. CONCLUSION: The Serbian version of the CDDQ scale is a valid and reliable instrument for the assessment of psychological distress among women with abnormal Pap smear results.

E4BP4/NFIL3 modulates the epigenetically repressed RAS effector RASSF8 function through histone methyltransferases.

RAS proteins are major human oncogenes, and most of the studies are focused on enzymatic RAS effectors. Recently, nonenzymatic RAS effectors (RASSF, RAS association domain family) have garnered special attention because of their tumor-suppressive properties in contrast to the oncogenic potential of the classical enzymatic RAS effectors. Whereas most members of RASSF family are deregulated by promoter hypermethylation, RASSF8 promoter remains unmethylated in many cancers but the mechanism(s) of its down-regulation remains unknown. Here, we unveil E4BP4 as a critical transcriptional modulator repressing RASSF8 expression through histone methyltransferases, G9a and SUV39H1. In line with these observations, we noticed a negative correlation of RASSF8 and E4BP4 expression in primary breast tumor samples. In addition, our data provide evidence that E4BP4 attenuates RASSF8-mediated anti-proliferation and apoptosis, shedding mechanistic insights into RASSF8 down-regulation in breast cancers. Collectively, our study provides a better understanding on the epigenetic regulation of RASSF8 function and implicates the development of better treatment strategies.

Synthesis of medium-chain length capsinoids from coconut oil catalyzed by Candida rugosa lipases.

A commercial preparation of Candida rugosa lipases (CRL) was tested for the production of capsinoids by esterification of vanillyl alcohol (VA) with free fatty acids (FA) and coconut oil (CO) as acyl donors. Screening of FA chain length indicated that C8-C12 FA (the most common FA found in CO triglycerides) are the best acyl-donors, yielding 80-85% of their specific capsinoids. Hence, when CO, which is rich in these FA, was used as the substrate, a mixture of capsinoids (vanillyl caprylate, vanillyl decanoate and vanillyl laurate) was obtained. The findings presented here suggest that our experimental method can be applied for the enrichment of CO with capsinoids, thus giving it additional health promoting properties.

Isoaspartyl formation in creatine kinase B is associated with loss of enzymatic activity; implications for the linkage of isoaspartate accumulation and neurological dysfunction in the PIMT knockout mouse.

Isoaspartate (isoAsp) formation is a common type of spontaneous protein damage that is normally kept in check by the repair enzyme protein-L-isoaspartyl methyltransferase (PIMT). PIMT-KO (knockout) mice exhibit a pronounced neuropathology highlighted by death from an epileptic seizure at 30 to 60 days after birth. The mechanisms by which isoaspartyl damage disrupts normal brain function are incompletely understood. Proteomic analysis of the PIMT-KO mouse brain has shown that a number of key neuronal proteins accumulate high levels of isoAsp, but the extent to which their cellular functions is altered has yet to be determined. One of the major neuronal targets of PIMT is creatine kinase B (CKB), a well-characterized enzyme whose activity is relatively easy to assay. We show here that (1) the specific activity of CKB is significantly reduced in the brains of PIMT-deficient mice, (2) that in vitro aging of recombinant CKB results in significant accumulation of isoAsp sites with concomitant loss of enzymatic activity, and (3) that incubation of in vitro aged CKB with PIMT and its methyl donor S-adenosyl-L-methionine substantially repairs the aged CKB with regard to both its isoAsp content and its enzymatic activity. These results, combined with similarity in phenotypes of PIMT-KO and CKB-KO mice, suggests that loss of normal CKB structure and function contributes to the mechanisms by which isoAsp accumulation leads to CNS dysfunction in the PIMT-KO mouse.

Ovarian endometroid adenocarcinoma in pregnancy.

BACKGROUND: Ovarian cancer is very rare in pregnancy. It is mainly of epithelial origin, low grade and low malignant potential. CASE REPORT: We presented a patient in which ultrasound confirmed the presence of clearly limited tumor in the left ovary when she was eight weeks pregnant. The results of 4D Color Doppler showed a central type of tumor vascularisation with resistance index (IR) less than 0.5. The Consultancy Board in Gynecology of the Institute for Oncology and Radiology of Serbia decided to remove the patient's left adnexa and intensively monitor the pregnancy period. The operation (Adnexectomia lateralis sinistra) was performed at 18th week of gestation. Histopathological analysis showed adenocarcinoma invasivum, endometroid well-differentiated type (histological grade I, nuclear grade 2). In 37th week of gestation, the patient gave birth to a male child by cesarean section. In the next 3 years the patient had no subjective interference, laboratory tests and ultrasonographic findings were normal. CONCLUSION: Ovarian cancer in pregnancy is usually asymptomatic and diagnosed during routine clinical and ultrasound examination. The color Doppler technique have particular importance in the diagnosis of pathological blood supply in tumors and in indication of malignant ovarian mass.

[Treatment of surgical wounds on the uterus after laparoscopic myomectomy].

INTRODUCTION: The advantages of laparoscopic removal of a myoma over classical surgical technique are shorter hospital stay, rapid recovery and less pain after surgery, as well as a lower frequency of ileus and thromboembolic complications. The surgical technique of laparoscopic removal of myoma involves four basic stages: incision on the wall of the uterus, separation of the myoma from the healthy uterine tissue, to stop bleeding and removal of the myoma from the abdomen. Apart from these four basic stages, it is also necessary to establish a new integrity of the uterine wall, especially in women planning pregnancy. OBJECTIVE: The aim of the paper is to present the procedures used in the treatment of uterine wall defect during the laparoscopic removal of the myoma. METHODS: We analysed 96 patients who were indicated for laparoscopic myomectomy. All patients were divided into four groups according to the type of the technique of haemostasis and treatment of the defect on the uterine wall: electrocoagulation, electrocoagulation with application of argon plasma, a single suture and extended suture. RESULTS: In order to stop bleeding, we most often used electrocoagulation by monopolar electricity, i.e. in 39.6% of the patients. To stop bleeding and treat the defect of the uterine wall, we used a single suture in 21.9% and in 11.4% patients we used the extended suture. The manner of uterine wall treatment did not have a statistically significant influence on the results of haematological parameters (p > 0.05), consumption of carbon dioxide (p > 0.05) and the duration of surgical procedure (p > 0.05). The increased use of antibiotics (p < 0.05) in the group of patients in whom we treated the defect by sutures on the uterus, the length of postsurgical hospitalisation and absence from work (p < 0.01) was statistically significant. CONCLUSION: To achieve a better reconstruction of the uterus, it is recommended to use sutures with laparoscopic removal of myoma.
