We report a patient with ovarian malignant mixed mesodermal tumor (MMMT) that produced immunoreactive human chorionic gonadotropin beta-subunit (IR-hCG beta). Qualitative analysis indicated that IR-hCG beta in the patient's serum represented the free form of the beta-subunit of hCG. Immunohistochemical localization of hCG beta in MMMT was observed in the sarcomatous stroma, but not in the adenocarcinoma component. Reverse transcription-polymerase chain reaction (RT-PCR) for hCG subunits revealed that the mRNA transcripts of two of six hCG beta genes (beta-1 and -2) were predominantly expressed in the tumor tissue. The serum level of free hCG beta correlated with disease status and was helpful for monitoring the response to therapy for MMMT in this patient.

A Modified Method for DNA Extraction From Buccal Cells for Genetic Epidemiological Studies Among Children.
Cureus
December 2024
Department of Clinical Research, University of San Luis Potosí, San Luis Potosí, MEX.
Background: In large-scale molecular studies, a protocol that generates high yields and quality DNA for future polymerase chain reaction (PCR) assays is needed. The collection of buccal cells by cytobrush may represent an efficient, noninvasive, and inexpensive method for obtaining genetic material from school populations. The aim of this study was to develop a method to obtain genomic DNA from buccal cells of schoolchildren, and the DNA was extracted immediately after collecting the buccal cell samples and after storing the samples for 8 months at -20 °C to establish the feasibility of the method for epidemiological studies.

Department of Gynecology-Obstetrics, Mohammed V Military University Hospital, Faculty of Medicine and Pharmacy, Mohammed V University, Rabat, Morocco.
Introduction And Importance: Uterine arteriovenous malformations (UAVMs) are rare vascular anomalies caused by abnormal connections between uterine arteries and veins. They can lead to severe bleeding, requiring prompt and accurate diagnosis. Historically treated with hysterectomy, transcatheter vascular embolization has emerged as a fertility-sparing alternative.

Am J Transl Res
December 2024
Obstetrics Department, Huzhou Maternity and Child Health Care Hospital Huzhou 313000, Zhejiang, China.
Objective: To investigate the effects of allylestrenol on sex hormone levels and delivery outcomes in women with threatened abortion.
Methods: This retrospective analysis examined clinical data of patients with threatened abortion treated at Huzhou Maternity & Child Health Care Hospital from January 1, 2021, to December 31, 2022. A total of 149 eligible patients were screened and divided into two groups: a control group (n=75) treated with progesterone capsules from January to December 2021, and an observation group (n=74) treated with allylestrenol from January to December 2022.
Pulmonary artery choriocarcinoma mimicking pulmonary thromboembolism: a case report.
Transl Cancer Res
December 2024
Department of Geriatric Respiratory Disease, Institute of Guangdong Provincial Geriatrics, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, China.
Background: Primary choriocarcinoma of the pulmonary artery is an exceedingly rare malignant neoplasm, which is often misdiagnosed due to its nonspecific clinical presentation. While this condition is characterized by the presence of trophoblastic cells, typically associated with gestational trophoblastic diseases, we encountered a case occurring in an extragenital location. The rarity of such tumors makes it challenging for clinicians to consider them in differential diagnosis, especially when the initial symptoms mimic more common conditions such as pulmonary thromboembolism (PTE).

Department of Medical Oncology and Haematology, All India Institute of Medical Sciences, Bhubaneswar, Odisha, India.
Extragonadal choriocarcinoma in men is an extremely rare and highly aggressive malignancy. Inconclusive biopsies due to a high necrotic component often delay diagnosis. Here is such a case, in which suggestive imaging findings on [F]FDG PET/CT, a raised level of serum β-human chorionic gonadotropin, and gynecomastia clinched the diagnosis.
