Comparison of the clinical, ultrasound, and CT findings in 13 dogs with gastric neoplasia.

Vet Radiol Ultrasound 2021 May 14. Epub 2021 May 14.

Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, Gainesville, Florida, USA.

Diagnosis of gastric tumors in dogs is difficult and is often obtained by biopsy following identification of a mass through ultrasound (US) or endoscopy. In human medicine, modalities such as CT and endoscopy are standard of care in the diagnosis and staging of gastric tumors. Although one veterinary study has described CT findings of gastric tumors in dogs using iatrogenic gas dilation, there are no veterinary studies that have directly compared the usefulness of US versus CT in the diagnosis and staging of these tumors.

Endoscopic submucosal dissection with SB Knife® for treatment of a subcardial gastric leiomyoma.

Rev Esp Enferm Dig 2021 May 5. Epub 2021 May 5.

Digestive Medicine, Hospital Clínico Universitario de Valencia.

Surgery has been considered the main treatment for submucosal tumors (SMTs); however, endoscopic resection is currently accepted for gastric SMTs smaller than 3cm. Endoscopic submucosal dissection (ESD) is considered the technique of choice and submucosal tunneling endoscopic resection shows successful results with low complication rate in the recent meta-analysis by Cao et al. The major limitation of these methods is the technical difficulty to be applied in certain anatomic locations. Read More

The Largest Uterine Leiomyoma Removed by Robotic-Assisted Laparoscopy in the Late Reproductive Age: A Case Report.

J Menopausal Med 2021 Apr;27(1):37-41

Department of Obstetrics and Gynecology, Seoul National University Bundang Hospital, Seongnam, Korea.

Uterine leiomyoma is a very common gynecological tumor in the reproductive years. Recent studies have shown that surgical treatment of uterine leiomyoma using robotic-assisted laparoscopic myomectomy (RALM) is associated with significantly fewer complications, lower estimated blood loss, fewer conversions, and less bleeding than conventional laparoscopic myomectomy. This study reports the case of a giant uterine leiomyoma treated using RALM. Read More

Benign Metastasizing Leiomyoma in the Heart of a 45-Year-Old Woman.

Tex Heart Inst J 2021 Jan;48(1)

Harrington Heart & Vascular Institute, Cardiovascular Medicine Department, University Hospitals Cleveland Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio.

We report a rare case of benign metastasizing leiomyoma in the heart of a 45-year-old woman 2 years after a uterine leiomyoma had been discovered during hysterectomy. Computed tomograms at presentation showed a large mixed cystic mass in the pelvis and bilateral lung nodules suggestive of metastatic disease. A large cardiac mass, attached to the chordae of the tricuspid valve and later shown to be histopathologically consistent with uterine leiomyoma, was successfully resected through a right atriotomy.

A Phase I Clinical Trial to Assess Safety and Tolerability of Injectable Collagenase in Women with Symptomatic Uterine Fibroids.

Reprod Sci 2021 Apr 29. Epub 2021 Apr 29.

Department of Gynecology and Obstetrics, Division of Reproductive Sciences & Women's Health Research, Johns Hopkins University School of Medicine, 720 Rutland Avenue, Ross Research Building, Room 624, Baltimore, MD, 21205, USA.

Uterine fibroids feature excessive deposition of types I and III collagen. Previous ex vivo studies showed an FDA-approved collagenase (EN3835)-digested types I and III collagen fibers in fibroid tissues; however, collagenase had not been evaluated in vivo for effects on uterine fibroids. The objective was to assess the safety and tolerability of collagenase injection directly into uterine fibroids. Read More

Fibroids and natural fertility: a systematic review and meta-analysis.

Reprod Biomed Online 2021 Mar 23. Epub 2021 Mar 23.

Department of Clinical Sciences and Community Health, Università degli Studi di Milano, Milan, Italy; Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Via M. Fanti, 6, Milan 20122, Italy.

Available evidence from IVF studies supports a detrimental effect of submucosal and intramural fibroids on embryo implantation. It is misleading, however, to infer evidence obtained in IVF settings to natural fertility. Therefore, a systematic review and meta-analysis was conducted on the effect of fibroids on natural fertility. Read More

The Multifaceted Role of Autophagy in Endometrium Homeostasis and Disease.

Reprod Sci 2021 Apr 20. Epub 2021 Apr 20.

Center for Reproductive Health Sciences, Department of Obstetrics and Gynecology, Washington University School of Medicine, BJC Institute of Health - 10th Floor, RM 10606, 425 S. Euclid Avenue, Campus Box 8064, St. Louis, MO, 63110, USA.

Autophagy is a conserved fundamental cellular process with a primary function of catabolizing harmful or surplus cellular contents such as protein aggregates, dysfunctional/long-lived organelles, intracellular pathogens, and storage nutrients. An increasing body of evidence reveals that basal autophagy is essential for maintaining endometrial homeostasis and mediating endometrial-specific functions, including menstrual cycle, embryo implantation, and decidualization. However, perturbed levels of autophagy can lead to severe endometrial pathologies, including endometriosis, endometrial hyperplasia, endometrial cancer, adenomyosis, and leiomyoma. Read More
