Thrombolysis for massive pulmonary embolism in pregnancy: a case report

Mortality from pulmonary embolism (PE) in pregnancy might be related to challenges in targeting the right population for prevention. Such targeting could help ensure that the correct diagnosis is suspected and adequately investigated, and allow the initiation of the timely and best possible treatment of this disease. In the literature to date only 18 case reports of thrombolysis in pregnant women with PE have been reported, and showed beneficial effects for both mother and fetus in terms of mortality and complications with acceptable bleeding risks. We present here the case of a pregnant patient with massive PE who underwent successful thrombolysis. A 26-year-old pregnant (at 24 weeks) woman was admitted 4 h after onset of sudden acute dyspnea and chest pain. An immediate electrocardiogram showed a typical S1-Q3-T3 pattern. The echocardiogram showed a distended right ventricle with free-wall hypokinesia and displacement of the interventricular septum toward the left ventricle. Thrombolysis with recombinant tissue plasminogen activator (alteplase 10 mg bolus, then 90 mg over 2 h) was administered. Pelvic examination and ultrasound showed regular fetal heart beat, and regular placental and liquid presence. No problems developed for the mother or fetus in the subsequent days or at discharge. In conclusion, in pregnant patients with life-threatening massive PE, thrombolytic therapy can be administered, and the use of echocardiographic, laboratory, and clinical data can be useful tools to achieve a rapid diagnosis and make a therapeutic decision, but additional studies need to be performed to further define its use

Новые возможности лучевой визуализации в диагностике местнораспространенного рака шейки матки

Cervical cancer is the second most common cancer after breast cancer and the third most common cause of cancer-related death followed by breast and lung cancers among women worldwide. advances in diagnostic imaging techniques provide better assessment of regional and distant cervical cancer metastasis. the use of contrast-enhanced ultrasound is a revolutionary imaging modality; it has several advantages over ct: no radiation exposure, nephrotoxicity, obtaining real-time information, relatively low cost and ease of use. currently, the contrast agent sonoVue is widely used in ultrasound imaging of liver, kidneys and pancreas lesions, as well as for closed abdominal injuries, multiple organ failure, breast and prostate cancers, etc. However, the role of contrast-enhanced ultrasound in gynecology is not clearly established. one of the most effective tools for the detection of locally advanced cervical cancer is mRi, which is used mainly to determine the local extent of the tumor. However, the use of functional mRitechniques has not yet been included in the standards. cervical cancer tissue has been found to show significantly lower diffusion-weighted imaging (dWi) values than normal cervical tissue, thus facilitating the detection of tumor and its spread. dWiis also used for differentiating changes after biopsy from residual tumor and for identifying small lymph nodes. the pEt/cttechnique combines the metabolic images of pEtwith anatomical images of ctand is more accurate than high resolution ctalone, especially in determining the involvement of regional lymph nodes and distant organs. 18-Fdg-pEt/cthas been successfully used for accurate staging of the disease (especially late stage), assessment of treatment response, radiotherapy planning, and detection of disease progression. in patients with advanced stages of cervical cancer (iiBiV stage), the 18-Fdg-pEt/ ctfindings can determine the treatment strategy in most cases, primarily due to high sensitivity (75–100 %) and specificity (87–100 %) in the detection of lymph node metastases.Рак шейки матки (РШМ) является второй по распространенности онкологической патологией у женщин после рака молочной железы, при этом показатели смертности занимают третье место после рака молочной железы и рака легкого. Прогресс развития лучевых методов диагностики способствует более адекватной оценке местной и отдаленной распространенности рака шейки матки. Использование контраста в эхографии признано революционным в лучевой диагностике, обладает рядом преимуществ перед КТ: отсутствие лучевой нагрузки, нефротоксичности, получение информации в режиме реального времени, относительно низкая стоимость и простота в применении. В настоящее время в мире используется контрастный препарат Соновью для ультразвукового исследования очаговых поражений печени, почек, поджелудочной железы, при закрытой травме живота, полиорганном поражении, при новообразованиях молочной железы, при раке предстательной железы и др. Однако роль ультразвукового метода с контрастным усилением в гинекологии не определена. Одним из наиболее прогрессивных методов диагностики местнораспространенного рака шейки матки является магнитно-резонансная томография, которая используется главным образом для определения местной распространенности процесса. В то же время применение функциональных методик МРТ до сих пор не включено в стандарты. Однако исследователями доказано, что РШМ показывает значительно более низкие значения диффузии (dWi), чем нормальная ткань шейки, облегчая обнаружение опухоли и определение степени ее распространенности. dWiтакже используется для дифференциальной диагностики между изменениями после биопсии и остаточной опухолью и способствует выявлению лимфатических узлов небольших размеров. Совмещенная методика позитронно-эмиссионная томография/компьютерная томография объединяет метаболические изображения ПЭТ с анатомическими изображениями КТ и более точна, чем только одна КТ с высоким разрешением, особенно в определении вовлечения регионарных лимфатических узлов и отдаленных органов. Современными исследованиями установлено, что применение 18-фтордезоксиглюкозы (18-ФДГ) с ПЭТ/КТ позволяет более надежно определить стадию заболевания (особенно позднюю) и, как следствие, его прогноз, оценить эффективность лечения, планировать лучевую терапию, а также выявить прогрессирование заболевания. У пациенток с запущенными стадиями РШМ (iiB–iV стадии) именно результаты 18-ФДГ-ПЭТ/КТ в большинстве случаев способны повлиять на тактику лечения, в первую очередь благодаря высокой чувствительности (75–100 %) и специфичности (87–100 %) в диагностике метастатического поражения лимфоузлов

Estrogen- and Progesterone (P4)-Mediated Epigenetic Modifications of Endometrial Stromal Cells (EnSCs) and/or Mesenchymal Stem/Stromal Cells (MSCs) in the Etiopathogenesis of Endometriosis

Endometriosis is a common chronic inflammatory condition in which endometrial tissue appears outside the uterine cavity. Because ectopic endometriosis cells express both estrogen and progesterone (P4) receptors, they grow and undergo cyclic proliferation and breakdown similar to the endometrium. This debilitating gynecological disease affects up to 15% of reproductive aged women. Despite many years of research, the etiopathogenesis of endometrial lesions remains unclear. Retrograde transport of the viable menstrual endometrial cells with retained ability for attachment within the pelvic cavity, proliferation, differentiation and subsequent invasion into the surrounding tissue constitutes the rationale for widely accepted implantation theory. Accordingly, the most abundant cells in the endometrium are endometrial stromal cells (EnSCs). These cells constitute a particular population with clonogenic activity that resembles properties of mesenchymal stem/stromal cells (MSCs). Thus, a significant role of stem cell-based dysfunction in formation of the initial endometrial lesions is suspected. There is increasing evidence that the role of epigenetic mechanisms and processes in endometriosis have been underestimated. The importance of excess estrogen exposure and P4 resistance in epigenetic homeostasis failure in the endometrial/endometriotic tissue are crucial. Epigenetic alterations regarding transcription factors of estrogen and P4 signaling pathways in MSCs are robust in endometriotic tissue. Thus, perspectives for the future may include MSCs and EnSCs as the targets of epigenetic therapies in the prevention and treatment of endometriosis. Here, we reviewed the current known changes in the epigenetic background of EnSCs and MSCs due to estrogen/P4 imbalances in the context of etiopathogenesis of endometriosis
