Choriocarcinoma complicated with intra-abdominal and intrapleural hemorrhage in pregnancy - case report.

Background: Choriocarcinoma is a rare neoplasm, exceptionally uncommon during an ongoing pregnancy. The disease often has a metastatic character, causing severe symptoms from various anatomic sites like the lungs, central nervous system, vagina, pelvis, or liver. Due to the condition's rarity, evidence on how to treat the choriocarcinoma originating during pregnancy remains scarce. Case presentation: Here, we present a case of a patient who developed choriocarcinoma before the 29th week of gestation. The neoplasm had a metastatic character, resulting in hemorrhage complicated by a hypovolemic shock. The patient underwent an emergency cesarean section and several surgeries to stop the massive hemorrhage. The treatment of the choriocarcinoma included chemotherapy with methotrexate followed by an EMA-CO regimen. The patient had a complete response to the therapy. The neonate suffered from complications related to prematurity. Conclusion: Metastatic choriocarcinoma can be a diagnostic and therapeutic challenge during ongoing pregnancy. Treatment of the disease can be associated with severe complications, but a complete response to chemotherapy is possible with a favorable long-term prognosis.

Cancer Stem Cell Markers-Clinical Relevance and Prognostic Value in High-Grade Serous Ovarian Cancer (HGSOC) Based on The Cancer Genome Atlas Analysis.

Cancer stem cells (CSCs) may contribute to an increased risk of recurrence in ovarian cancer (OC). Further research is needed to identify associations between CSC markers and OC patients' clinical outcomes with greater certainty. If they prove to be correct, in the future, the CSC markers can be used to help predict survival and indicate new therapeutic targets. This study aimed to determine the CSC markers at mRNA and protein levels and their association with clinical presentation, outcome, and risk of recurrence in HGSOC (High-Grade Serous Ovarian Cancer). TCGA (The Cancer Genome Atlas) database with 558 ovarian cancer tumor samples was used for the evaluation of 13 CSC markers (ALDH1A1, CD44, EPCAM, KIT, LGR5, NES, NOTCH3, POU5F1, PROM1, PTTG1, ROR1, SOX9, and THY1). Data on mRNA and protein levels assessed by microarray and mass spectrometry were retrieved from TCGA. Models to predict chemotherapy response and survival were built using multiple variables, including epidemiological data, expression levels, and machine learning methodology. ALDH1A1 and LGR5 mRNA expressions indicated a higher platinum sensitivity (p = 3.50 × 10-3; p = 0.01, respectively). POU5F1 mRNA expression marked platinum-resistant tumors (p = 9.43 × 10-3). CD44 and EPCAM mRNA expression correlated with longer overall survival (OS) (p = 0.043; p = 0.039, respectively). THY1 mRNA and protein levels were associated with worse OS (p = 0.019; p = 0.015, respectively). Disease-free survival (DFS) was positively affected by EPCAM (p = 0.004), LGR5 (p = 0.018), and CD44 (p = 0.012). In the multivariate model based on CSC marker expression, the high-risk group had 9.1 months longer median overall survival than the low-risk group (p < 0.001). ALDH1A1, CD44, EPCAM, LGR5, POU5F1, and THY1 levels in OC may be used as prognostic factors for the primary outcome and help predict the treatment response.

Catamenial pneumothorax - are there benefits of cooperation between the surgeon and the gynaecologist?

Catamenial pneumothorax (CP) is an uncommon disease related to thoracic endometriosis or diaphragmatic perforation. It is defined as an occurrence of spontaneous pneumothorax around the time of menstruation in the population of women of reproductive age with no other lung diseases. Catamenial pneumothorax is often misdiagnosed and classified as a spontaneous pneumothorax, and no in-depth gynaecological diagnostic is performed. Here we present 3 cases of female patients admitted to the Department of Thoracic Surgery with the aim of surgical treatment of recurrent CP. In all 3 cases, a temporal association between pneumothorax and menstruation was identified. In 2 presented cases the patients were diagnosed with endometriosis and other gynaecological diseases. The previous incidents of CP were treated conservatively, with suction drainage of the pleural cavity or with thoracocentesis, but the treatment did not prevent relapses. In the Department of Thoracic Surgery, each patient was operated on with the use of video-assisted thoracoscopic surgery, which is considered to be a good therapeutic option. In the case of 2 patients the surgery eliminated the relapses, 1 patient required radical lung decortication. The literature on the subject indicates the potential benefits of hormonal treatment of CP. It is suggested that using such pharmacological treatment may reduce the risk of relapse after surgery.

Liver biopsies in children indications, techniques, results and complications. A single-centre study.

INTRODUCTION: Liver biopsy is a safe and helpful diagnostic tool for many liver disorders. It can be performed using various techniques. Regardless of the technique, the liver biopsy is considered to be a safe procedure. AIM OF THE STUDY: We aimed to analyze the indications, techniques, results, and complications of liver biopsies in the paediatric age group. MATERIAL AND METHODS: We retrospectively obtained the data from the medical history records of 63 paediatric patients who underwent the liver biopsy. The data were analyzed statistically. RESULTS: The most often performed type of biopsy was core needle biopsy (tru-cut), followed by core needle aspiration biopsy, fine-needle aspiration biopsy, open biopsy, and laparoscopic biopsy. Complications in the form of hematoma occurred only in 2 cases. The most common indications for the procedure were viral hepatitis monitoring/diagnosis, focal lesions, and autoimmune hepatitis. The histopathological results were predominantly hepatitis (viral and non-viral) and neoplasm. CONCLUSIONS: Liver biopsy is a safe procedure regardless of the technique used to obtain a tissue sample. Therefore, it should not be avoided when it is indicated.

Misinformation, Fears and Adherence to Preventive Measures during the Early Phase of COVID-19 Pandemic: A Cross-Sectional Study in Poland.

The response to the pandemic requires access to accurate information and public understanding and adherence to preventive measures. This online cross-sectional study of adult Poles (n = 1337) assessed the frequency of COVID-19 preventive behaviors, fears related to the COVID-19 pandemic, and beliefs in COVID-19-related conspiracy theories during the early phase of the COVID-19 pandemic when the nationwide lockdown was imposed (April 2020). As shown, 22% of surveyed admitted not to wash their hands frequently, while 12% did not use disinfectants. These two behaviors were also less frequent in individuals with medical education. The highest levels of pandemic-related fears were associated with health loss in relatives, pandemic-induced economic crisis, and government using a pandemic to control citizens by the state. A significant share of surveyed individuals believed that the pandemic was intentional action to weaken non-Chinese economies (32%) or was deliberately induced for profits from selling vaccines (27%). Men, individuals with no children, and subjects with lower education were significantly less likely to adhere to sanitary measures (handwashing, disinfection, avoiding face touching, changes in greeting etiquette, face-covering when coughing or sneezing), and were less concerned over self and relatives' health. At the same time, men were less prone than women to the conspiracy theories related to the COVID-19 pandemic. The results indicate that adherence to sanitary measures during the pandemic can be a challenge also in developed countries, while misinformation campaigns (also concerning vaccines) have already affected the general public during the early phase of the epidemiological outbreak. The study provides observations that may be useful in the management of the public response to future epidemics.
