Applicability of sonoelastography in leiomyoma and adenomyosis

Background. Uterine leiomyoma and endometriosis are common gynecological diseases of women in childbearing potential. This fact necessitates developing an optimal protocol for examination of patients in order to implement an individual approach to treatment. Diagnosis of mixed forms of pathological myometrium conditions causes some difficulties. Elastography technique makes it possible to assess the density of the myometrium, which may be essential for differentiating the diagnosis of leiomyoma and adenomyosis in mixed forms. Рurpose – to ascertain the potential of transvaginal ultrasound along with compression sonoelastography to determine the deformation coefficient in differential diagnosis of various pathological myometrium conditions. Materials and methods. The paper presents the analysis of elastographic findings of the uterus in 155 women obtained via compression sonoelastography performed by means of HITACHI AVIUS device. Patients were divided into 4 groups: control, women with uterine leiomyoma, uterine adenomyosis, with combined leiomyoma and adenomyosis. The transabdominal/ transvaginal ultrasound findings were confirmed by histopathological examination. The standard point scale was used to determine the deformation coefficient. Results. Elastographic characteristics were assessed in accordance with sonoelastography findings, i. e. deformation coefficients common in leiomyoma and adenomyosis. The maximum values of the deformation coefficient were obtained in leiomyoma (in an amount of 2 to 6.0 units). In case of diffuse or focal adenomyosis, the deformation coefficient was in an amount of 0.5 to 1.5 units indicating high myometrial elasticity vs the unchanged myometrium. For its part, in Group I (control), the deformation coefficient ranged from 1 to 1.7 units. High myometrial elasticity in adenomyosis vs the unchanged myometrium as well low elasticity or high density of the myometrium in leiomyoma were observed. Conclusions. The deformation coefficients in patients with leiomyoma and adenomyosis and unchanged myometrium were obtained via ultrasound with compression sonoelastography and they made it possible to determine the degree of elasticity of the myometrium and its changes in the relevant pathology. Elastography is capable of identifying clear distinctive features of leiomyoma and adenomyosis. The coincidence of the diagnosis of adenomyosis based on elastography and histology is significant, but not optimal. The unchanged myometrium has a certain elasticity, which can be equated to a numerical value, i. e. the deformation coefficient, and this param changes in case of leiomyoma or adenomyosis, which makes it possible to differentiate these pathological conditions of the myometrium.

The aim of the study: was improvement of results of surgical treatment of patients of reproductive age eligibility with hyperplastic processes of endometrium (HPE) through the introduction of individualized treatment algorithm with the use of monopolar radio wave and hysteroscopic endometrial ablation. Materials and methods. The study included 62 women with non-atypical form of hyperplasia of the endometrium who were treated at the Center of General gynecology of the clinical hospital «Feofania», gynecological Department at the city maternity hospital № 3 of Kyiv. Depending on the age group, nature of the pathological process and method of treatment is randomized, the distribution of women according to groups: group 1 – 41 women's reproductive eligibility age netipichnaya forms of endometrial hyperplasia (PHEBA and KGEB), who were subjected to hysteroscopic monopolar endometrial ablation; group 2 – 21 female reproductive eligibility age netipichnaya forms of endometrial hyperplasia (PHEBA and KGEB), which was held radiowave ablation of the endometrium (RHAE). In the 1st group the age of patients ranged from 42 to 54 years, mean age was 49.9±4.7 years. In the 2nd group the age of patients ranged from 41 to 53 years, mean age of 51.6±4.3 years. Results. A comparative analysis of the techniques for hysteroscopic monopolar ablation and RHEE showed the fact that for RHEE used local anesthesia, while carrying out hysteroscopic monopolar ablation was necessary intravenous anesthesia. The duration of the hysteroscopic monopolar endometrial ablation was 28.6±5.5 min, RAE – according to the standard method – 44.3±0.3 min. When performing hysteroscopic monopolar endometrial ablation in 2 patients (3.7%) patients observed the signs of intravasation of fluid, increased blood pressure and tachycardia. This syndrome was successfully docked, but in the future, women have conducted a thorough examination. When you run RHAE intraoperative complications have been identified. Conclusion. 1. Women with netipichnaya forms of endometrial hyperplasia eligibility and late reproductive age who do not have reproductive plans as an alternative to hysterectomy, in the presence of contraindications or ineffectiveness of hormone treatment may be recommended or radiowave monopolar hysteroscopic ablation of the endometrium. 2. Monopolar hysteroscopic endometrial ablation is indicated for women with netipichnaya forms of endometrial hyperplasia, can be used in the presence of submucous form of uterine fibroids, postoperative scars on the uterus, but in the absence of adenomyosis II–III degree. The effectiveness of monopolar hysteroscopic endometrial ablation in women with non-atypical form of hyperplasia of the endometrium is 87.8%. 3. Women after endometrial ablation should be under observation for two years. The method of choice for dynamic monitoring of the condition of the uterus in women who underwent endometrial ablation is transvaginal ultrasound which should be performed after 1, 3, 6, 12 and 24 months of follow up. 4. In case of recurrence of hyperplastic process of the endometrium (bleeding, thickening of the M-mode echo according to the ultrasound) shows a hysteroscopy with a mandatory histopathological examination and verification of the diagnosis. Key words: endometrial hyperplasia, women eligibility age, women of reproductive age, ablation of the endometrium.

Ameliorative Effect

The ameliorative effect of L-arginine (LA) and L-carnitine (LC) against fipronil (FPN)-induced neurotoxicity was explored. In this case, 36 adult male rats were randomly divided into six groups: group I received distilled water, group II received 500 mg/kg LA, group III received 100 mg/kg LC, group IV received 4.85 mg/kg FPN, group V received 4.85 mg/kg FPN and 500 mg/kg LA and group VI received 4.85 mg/kg FPN and 100 mg/kg LC for 6 weeks. Cognitive performance was assessed using Barnes maze (BM). Serum corticosterone, brain total antioxidant capacity (TAC), malondialdehyde (MDA) and dopamine were measured. Histopathology and immunohistochemistry of ionized calcium-binding adaptor (Iba-1), doublecortin (DCX) and serotonin (S-2A) receptors were performed. Fipronil induced noticeable deterioration in spatial learning and memory performance. In addition, FPN significantly (p < 0.05) diminished brain antioxidant defense system and dopamine coincide with elevated serum corticosterone level. Histopathological examination revealed degenerative and necrotic changes. Furthermore, Iba-1 and DCX were significantly expressed in cortex and hippocampus whereas S-2A receptors were significantly lowered in FPN group. However, administration of LA or LC alleviated FPN-induced deteriorations. In conclusion, LA and LC could be prospective candidates for mitigation of FPN-induced neurotoxicity via their antioxidant, anti-inflammatory and neuropotentiating effects.

Summary Objective: There have been many studies on adenomyosis, which can impair the quality of life of a woman. There are various kinds of opinions on the pathogenesis, diagnostics and treatment of adenomyosis. The goal of this article is to present the current knowledge of adenomyosis and its impact on the endometrial function and receptivity. Methods: PubMed/Medline, Web of Sciences and Scopus were searched for the articles in English indexed until February 2021 with terms of: adenomyosis, endometrial receptivity, and infertility. Results: Recent studies on angiogenesis and epithelial-mesenchymal transition in the endometrium bring new information on the ethiology and pathogenesis of adenomyosis. In clinical practice, the main diagnostic methods of adenomyosis include transvaginal ultrasound, magnetic resonance imaging or hysteroscopy, although the definitive confirmation is set by histopathological examination. The rules of #Enzian classification of endometriosis should be applied for the classification of adenomyosis. The treatment of adenomyosis should consider individual clinical presentation and reproductive plans of a patient and should be performed in centers for the treatment of endometriosis. Conclusion: Adenomyosis affects endometrial vascularisation and epithelial-mesenchymal transition/mesenchymal-epithelial transition; thus, it can be the cause of irregular uterine bleeding or embryo implantation failure. The research and analysis of endometrial proteome could lead to the new ways of adenomyosis treatment.

Extensive Resection

Endometriosis is the presence of the uterine endometrium beyond the uterus. The disease usually affects women of childbearing age. Foci of endometriosis are mostly (in 95% of cases) located in the peritoneal cavity (cervix uteri, vaginal vault, vulva, urinary bladder, inguinofemoral region) and only rarely found beyond it. Occasionally, endometriosis is found in the perineal tissues, usually in the episiotomy scar, and, exceptionally rarely, in the anorectal region. Endometriosis usually develops in the period of hormonal activity. The disease may be asymptomatic or manifest with dyspareunia, pelvic pain syndrome, fertility problems, menstrual disorders and heavy menstruation. The diagnosis of anorectal endometriosis is established through a thorough interview and additional tests, including transrectal and transvaginal ultrasound or optionally magnetic resonance imaging. The final diagnosis is determined in a histopathological examination, usually of samples collected intraoperatively. Also, an endoscopic examination should be performed (at least rectoscopy) to rule out other pathological lesions. Treatment includes pharmacotherapy and surgery. In young patients, in the period of hormonal activity, extensive resection with primary sphincter reconstruction seems to be the most optimal option. In older patients, nearing menopause, conservative treatment is a better solution as endometriosis regresses and disease symptoms subside after menopause. In these cases, conservative treatment helps avoid iatrogenic sphincter injury and faecal incontinence.

Scanty Information

Asparagus africanus Lam. is a plant used traditionally to treat different ailments. Currently, scanty information is available on its safety. The aim of this study is to determine the acute toxicity of the methanolic extract on vital organs and its associated biochemical parameters. Fifteen female Sprague-Dawley rats were divided into five groups. Group I served as normal control, groups II, III, IV, and V were orally administered single dose of crude extract dissolved in distilled water at 5 mg/kg BW, 50 mg/kg BW, 300 mg/kg BW and 2,000 mg/kg BW. Rats were observed for 14 days and body weights were recorded. On day 15, the rats were sacrificed and blood samples were collected for biochemical and haematological analyses, while the liver and kidneys were sampled for histopathological examination. Body weight and haematology parameters results showed significance difference (p < 0.05) among means of HGB, RDW, RBC, and MCHC; likewise, (p < 0.001) for WBC and platelet among treated groups. Histopathology result showed that kidneys appeared normal while livers were congested with mildly swollen hepatocytes and occasional binucleation. Focal lobular hepatitis was observed in all treated animals. However, hepatic enzymes were not significantly affected and no histopathological harmful effects were observed in kidney. In conclusion, methanolic extracts of A. africanus are safe up to 2,000 mg/kg BW. The obtained results could be used as a justification for the traditional application of the plant for treatment of various ailments.

Population Based Survey

Abstract Background Recent guidelines recommend a cranial ultrasound (CU) in neonates born at < 30 weeks gestation, admitted to the neonatal intensive care unit (NICU), or with a CU indication. Here, we addressed the need to extend these recommendations. Methods We retrospectively reviewed 5107 CUs acquired in the population-based Survey of Neonates in Pomerania, conducted in 2002 to 2008. Neonates with conspicuous CUs that were ≥ 30 weeks gestation without recent indications for CU were identified and assigned to the following groups: with (I) or without (II) admission to neonatal care. We designated CU conspicuities as mild (MC) or significant (SC), and we investigated related neurodevelopment during follow-up. Results Of 5107 neonates, 5064 were born at ≥30 weeks gestation and of those, 4306 received CUs without any indication for this examination. We found conspicuities in 7.7% (n = 47/610) of group I (n = 30 MC, n = 17 SC), and 3.2% (n = 117/3696) of group II (n = 100 MC, n = 17 SC). In group II, SC comprised, e.g., bilateral cysts, partial agenesis of the corpus callosum, and periventricular leukomalacia. Follow-up was available in 75% of infants in group II with MCs and SCs; of these, 12.8% had an abnormal neurological follow-up. Conclusions We detected a high number of conspicuities in neonates without a CU indication. However, we could not demonstrate that ultrasound findings were associated with the neurological follow-up or any advantage to an earlier diagnosis. Our data did not support extending current guidelines or a general CU screening policy for all neonates.

Newcastle disease (ND) remains one of the most harmful poultry diseases that threaten the poultry industry producers all over the world, thus the present work was planned to investigate the hematological, biochemical, and pathological changes in vaccinated and non-vaccinated broiler chickens naturally infected with ND. The study was conducted on 45 broiler chickens, 35-days-old, from a private farm in Damietta governorate and used in this work, 15 chickens were clinically healthy (Group I), 30 chickens with ND symptoms divided into 15 non-vaccinated (Group II) and the other 15 chickens (Group III) were vaccinated with La Sota strain of NDV with a titre of 106.5 EID50. The disease was diagnosed by hem agglutination test as ND. Blood and tissue samples were collected for clinical-pathological and histopathological examination. The infected broiler chickens showed cyanosis, nasal discharge, edema of eyelid and white pasty diarrhea with nervous manifestations. Furthermore, microcytic hypochromic anemia with leukocytosis was observed. Biochemical studies revealed a significant decrease in serum total proteins, albumin and A/G ratio, with significant increases in serum activities of aspartate aminotransferase, creatinine, and uric acid and glucose concentration in addition to several histological alterations were significantly seen in brain, intestine, liver and kidney of the infected birds. All these disturbances were less severe in the vaccinated group than the non-vaccinated one. In conclusion, La Sota vaccine can increase the bird resistant against Newcastle disease virus induced blood disorders and hepatic-renal insufficiency in broiler chickens.

Background: Hysterectomy is the most common gynecological surgery done in the females worldwide as it provides definitive cure to a wide range of gynecological diseases, both benign and malignant. The indications to perform this major surgery should always be justified and the pathology should be proved histopathologically. Histopathological analysis and review is mandatory to evaluate the appropriateness of the hysterectomy.Methods: A retrospective, longitudinal study was conducted in the Department of Obstetrics and Gynecology, UMAID Hospital, Dr. S.N. M.C. Jodhpur (Raj.) during October 2014 to March 2015.Total 105 cases were studied during this period. The study included all women undergoing planned abdominal hysterectomy. Data was recorded on proformas, including demographic characteristics and clinical features. Hysterectomy specimens were saved in 10% formalin and sent to the Department of Pathology. Histopathology reports were analyzed and compared with the indications of surgery to draw various informative conclusions.Results: Of 105 cases, 55(52.38%) were in the age group of 41 – 50, which comprised the commonest age group undergoing the surgery. Maximum women (95%) those underwent hysterectomy were multiparous. Most common preoperatively clinical diagnosis was leiomyoma uterus which was diagnosed clinically and sonographically in 51(48.57%) cases. On Histopathological examination, the commonest pathology, similar to clinical impression, was found to be Leiomyoma at 50.48% (n = 53). Adenomyosis (21.90%) was detected as Second most common pathology. Histopathological confirmation of pre-operative diagnosis was 89% for malignancy, 96% for fibroids, 100% for adenomyosis, 100% for pelvic inflammatory disease.Conclusions: There was a high correlation when the clinical diagnosis was a fibroid, adenomyosis and ovarian mass. Every hysterectomy specimen should be subjected to histopathological examination because it is mandatory for conforming diagnosis and ensuring optimal management, in particular of malignant disease.
