Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disease frequently associated with ovarian teratomas. In cases where an ovarian teratoma is identified, treatment involves prompt removal of the ovarian teratoma, resulting in significant clinical improvement and decreased incidence of relapse. We present the case of a 14-year-old female patient admitted for progressively worsening psychiatric and neurological status, diagnosed with anti-NMDAR encephalitis, and negative initial imaging for ovarian pathology. She was in the hospital for 8 months requiring admission to the intensive care unit and multiple courses of immunotherapy before clinical improvement. Three months after discharge, she was readmitted with clinical relapse and repeat imaging showed an ovarian teratoma. Removal of the teratoma resulted in sustained clinical improvement with return to baseline and no further relapse. Our case report highlights the importance of maintaining a high suspicion for an underlying ovarian teratoma in a female patient with anti-NMDAR encephalitis, even when initial imaging is negative. Currently, there are limited data on recommendations for repeat imaging. Therefore, we recommend repeat imaging in patients resistant to multiple lines of treatment or presenting with clinical relapse.

Leiomyomas are usually easily identifiable on routine imaging. However, there is increasing difficulty with diagnosing leiomyomas following degeneration. Subserosal leiomyomas that undergo cystic degeneration can imitate ovarian pathology. We present the case of a 39-year-old nulligravid woman who underwent surgery for a large pelvic mass originally suspected to be of ovarian origin. Intraoperatively, the mass was found to originate from the uterus and determined to be a large pedunculated, fluid-filled cyst arising from a fibroid which had undergone cystic degeneration. The mass was successfully removed laparoscopically through a single, two-centimeter port. Gynecologists and radiologists should take into account this presentation when encountering suspected enlarged ovarian cysts without clearly identifying an origin. Laparoscopic intervention should be considered as the first line of management.

Background: Mortality from ovarian cancer remains high due to the lack of methods for early detection. The difficulty lies in the low prevalence of the disease necessitating a significantly high specificity and positive-predictive value (PPV) to avoid unneeded and invasive intervention. Currently, cancer antigen- 125 (CA-125) is the most commonly used biomarker for the early detection of ovarian cancer. In this study we determine the value of combining macrophage migration inhibitory factor (MIF), osteopontin (OPN), and prolactin (PROL) with CA-125 in the detection of ovarian cancer serum samples from healthy controls. Materials and Methods: A total of 432 serum samples were included in this study. 153 samples were from ovarian cancer patients and 279 samples were from age-matched healthy controls. The four proteins were quantified using a fully automated, multi-analyte immunoassay. The serum samples were divided into training and testing datasets and analyzed using four classification models to calculate accuracy, sensitivity, specificity, PPV, negative predictive value (NPV), and area under the receiver operating characteristic curve (AUC). Results: The four-protein biomarker panel yielded an average accuracy of 91% compared to 85% using CA-125 alone across four classification models (p = 3.224 × 10⁻⁹). Further, in our cohort, the four-protein biomarker panel demonstrated a higher sensitivity (median of 76%), specificity (median of 98%), PPV (median of 91.5%), and NPV (median of 92%), compared to CA-125 alone. The performance of the four-protein biomarker remained better than CA-125 alone even in experiments comparing early stage (Stage I and Stage II) ovarian cancer to healthy controls. Conclusions: Combining MIF, OPN, PROL, and CA-125 can better differentiate ovarian cancer from healthy controls compared to CA-125 alone.

Adhesions frequently occur postoperatively, causing morbidity. In this noninterventional observational cohort study, we enrolled patients who presented for repeat abdominal surgery, after a history of previous abdominal myomectomy, from March 1998 to June 20210 at St. Vincent’s Catholic Medical Centers. The primary outcome of this pilot study was to compare adhesion rates, extent, and severity in patients who were treated with intraperitoneal triamcinolone acetonide during the initial abdominal myomectomy (n = 31) with those who did not receive any antiadhesion interventions (n = 21), as documented on retrospective chart review. Adhesions were blindly scored using a standard scoring system. About 32% of patients were found to have adhesions in the triamcinolone group compared to 71% in the untreated group (p < 0.01). Compared to controls, adhesions were significantly less in number (0.71 vs. 2.09, p < 0.005), severity (0.54 vs. 1.38, p < 0.004), and extent (0.45 vs. 1.28, p < 0.003). To understand the molecular mechanisms, human fibroblasts were incubated in hypoxic conditions and treated with triamcinolone or vehicle. In vitro studies showed that triamcinolone directly prevents the surge of reactive oxygen species triggered by 2% hypoxia and prevents the increase in TGF-β1 that leads to the irreversible conversion of fibroblasts to an adhesion phenotype. Triamcinolone prevents the increase in reactive oxygen species through alterations in mitochondrial function that are HIF-1α-independent. Controlling mitochondrial function may thus allow for adhesion-free surgery and reduced postoperative complications.

Objectives: HBB-related significant hemoglobinopathies have been anecdotally associated with low fetal fraction on noninvasive prenatal screening (NIPS). We sought to compare the difference in fetal fraction using NIPS in women with HBB-related significant hemoglobinopathies (HSH) and women with normal hemoglobin. Study design: This is a retrospective case-control study. Cases were women with a diagnosis of HSH using NIPS from a commercial laboratory. The comparison group was women with hemoglobin AA from a tertiary care center database. We tested for differences in median fetal fraction using quantile regression analysis, adjusting for maternal body weight and gestational age. Results: This study includes 35 women with clinically significant HSH and a comparison group of 636 women with hemoglobin AA. Adjusting for gestational age and body weight, the median fetal fraction was 4.1 point lower in the HSH than in the comparison group (β − 4.1; 95% −5.7 to −2.5, p < .05). The rate of no-calls due to low fetal fraction was significantly higher in the clinically significant HSH group than in the comparison group [HSH: n = 9/35, 25.7% versus comparison: n = 32/636, 5.0% (p < .001)]. Conclusion: Women with HSH were more likely to have a lower fetal fraction and ultimately a five-fold higher no-call rate. What’s already known about this topic?
