SMARCA4 loss irrelevant for mutated ovarian clear cell carcinoma: A case report.

Clear cell carcinomas are rare and relatively chemo-insensitive ovarian cancers with a characteristic molecular pathogenesis. Alterations in , a component of the multiprotein chromatin remodeling complex SWI/SNF, are likely early events in the development of ovarian clear cancers arising from atypical endometriosis. Insight into additional driver events and particularly mutations in the same chromatin remodeling complex is limited.

Aberrant nuclear β-catenin distribution does not prognosticate recurrences of endometrioid endometrial cancers - A retrospective single-institutional study.

Objective: Aberrant β-catenin distribution has been theorized as a predictive biomarker for recurrence in early stage, low grade endometrioid endometrial cancer.

Methods: This retrospective single-institution cohort study reviewed 410 patients with endometrial cancer from May 2018 to May 2022. Only endometrioid histology was included.

Incisional infiltration versus transversus abdominis plane block of liposomal bupivacaine after midline vertical laparotomy for suspected gynecologic malignancy: a pilot study.

Background: To evaluate whether incisional infiltration of liposomal bupivacaine would decrease opioid requirement and pain scores after midline vertical laparotomy for suspected or known gynecologic malignancy compared with transversus abdominis plane (TAP) block with liposomal bupivacaine.

Methods: A prospective, single blind randomized controlled trial compared incisional infiltration of liposomal bupivacaine plus 0.5% bupivacaine versus TAP block with liposomal bupivacaine plus 0.

Reactivated disseminated tuberculosis in pregnancy: Case report and review of the literature.

This case report describes the evaluation and management of a 32-year-old woman who presented shortly after a fetal demise at 23 weeks of gestation with multiple symptoms, including bloody vaginal discharge. Although the initial diagnostic concern was for metastatic malignancy, the patient was ultimately determined to have disseminated tuberculosis. Genital tuberculosis is common worldwide, yet guidelines for evaluation are limited.

Technetium Tc 99m tilmanocept fails to detect sentinel lymph nodes in endometrial cancer.

Background: Technetium Tc 99m tilmanocept is a synthetic radiotracer specifically designed for sentinel lymph node (SLN) mapping that has been FDA-approved in breast cancer, melanoma, and head and neck cancer. No published studies exist for the use of this radiotracer in endometrial cancer.

Objective: The primary objective was to determine the detection rate of bilateral SLNs in endometrial cancer with the concurrent use of technetium Tc 99m tilmanocept and ICG.

Long-term efficacy of megestrol acetate and tamoxifen in a recurrent adult granulosa cell tumor of the ovary.

•Recurrent, non-resectable ovarian granulosa cell tumor has no standard treatment.•Estrogen/progesterone receptor signaling regulates granulosa cell tumor growth.•Granulosa cell tumor responds well to alternating megestrol and tamoxifen therapy.

Digital Mass Analysis in a Linear Ion Trap without Auxiliary Waveforms.

Mass analysis in a linear ion trap is traditionally performed using resonant ejection induced by auxiliary waveforms. For sinusoidally driven ion traps without resonant ejection, resolution and sensitivity are poor because mass-selected instability yields excitation along both the and axes simultaneously. Digital ion traps, on the other hand, have the advantage of duty cycle manipulation that can be used to change the ion excitation along the and axes.

Clinical Utility of Preoperative Assessment in Ovarian Cancer Cytoreduction.

Ovarian cancer is the deadliest gynecologic cancer, in part due to late presentation. Many women have vague early symptoms and present with disseminated disease. Cytoreductive surgery can be extensive, involving multiple organ systems.

Radical Trachelectomy for the Treatment of Early-Stage Cervical Cancer: A Systematic Review.

Objective: To assess surgical, oncologic, and pregnancy outcomes in patients undergoing radical vaginal, abdominal, or laparoscopic trachelectomy for the treatment of early-stage cervical cancer, using a methodic review of published literature.

Data Sources: PubMed, EMBASE, and Cochrane Library sources, including ClinicalTrials.gov, were searched from 1990-2019 with terms "cervical cancer" and "(vaginal, abdominal, open, minimally invasive, or laparoscopic) radical trachelectomy.

Removal of 132-pound ovarian mucinous cystadenoma: A case report.

Ovarian masses larger than 100 pounds are rarely encountered in developed countries given advancements in early diagnosis and treatment. Their successful resections pose unique surgical and anesthetic challenges. An otherwise healthy 38-year-old para 1 woman developed a 50 × 60 cm pelvic mass.

Robotic Surgery in Gynecology.

The robotic-assisted laparoscopic surgical approach has improved complex gynecologic surgeries. It has the advantages of excellent visualization through the high-resolution 3-dimensional view, a wrist-like motion of the robotic arms and improved ergonomics. Similar to conventional laparoscopic surgeries, it is associated with a decrease in long-term surgical morbidity, early recovery and return to work, and improved esthetics.

Fetal one-carbon nutrient concentrations may be affected by gestational diabetes.

Both insufficiency and excess of one-carbon nutrients (folate, choline, vitamins B6 and B12) during pregnancy have been associated with gestational diabetes mellitus (GDM). However, the precise nature of this association has not been clearly established. We hypothesized that GDM may affect one-carbon nutrients concentrations in the fetus, thus possibly participating in epigenetic programing of the offspring.

Digital Waveform Technology and the Next Generation of Mass Spectrometers.

Ion traps and guides are integral parts of current commercial mass spectrometers. They are currently operated with sinusoidal waveform technology that has been developed over many years. Recently, digital waveform technology has begun to emerge and promises to supplant its older cousin because it presents new capabilities that result from the ability to instantaneously switch the frequency and duty cycle of the waveforms.

Vulvar yolk sac tumor diagnosed during pregnancy, with recurrence during subsequent second pregnancy.

•Vulvar yolk sac tumor (YST) is an exceptionally rare and aggressive extra-gonadal germ cell tumor, previously only described in 15 cases in the literature.•We present a unique case of vulvar YST diagnosed during pregnancy, treated with systemic chemotherapy, who subsequently recurred during a second pregnancy.•Despite salvage chemotherapy and autologous stem cell transplantation at recurrence, our patient succumbed to her disease, 31 months post diagnosis.
