ASRM müllerian anomalies classification 2021.

There are many proposed classification systems for müllerian anomalies. The American Fertility Society (AFS) Classification from 1988 has been the most recognized and utilized. The advantages of this iconic classification include its simplicity, recognizability, and correlation with clinical pregnancy outcomes. However, the AFS classification has been criticized for its focus primarily on uterine anomalies, with exclusion of those of the vagina and cervix, its lack of clear diagnostic criteria, and its inability to classify complex aberrations. Despite this classification and others, the wide range of müllerian anomalies is still largely unknown and confusing to many providers. Consequently, müllerian anomalies may go undiagnosed for extended periods, receive inappropriate or inadequate surgical interventions, and result in persistent issues such as pain or loss of reproductive function. The American Society for Reproductive Medicine Task Force on Müllerian Anomalies Classification was formed and charged with designing a new classification. The Task Force set goals for a new classification and chose to base it on the iconic AFS classification from 1988 because of its simplicity and recognizability, while expanding and updating it to include all categories of anomalies. In addition, this was recognized as an opportunity to raise awareness of this area of medicine, educate providers and learners, and promote patient advocacy. Presented here is the new American Society for Reproductive Medicine Müllerian Anomalies Classification 2021.

Thyrotoxicosis and bilateral internal carotid artery dissections.

Cervical artery dissection is a rare but important diagnosis to consider in young patients presenting with stroke. Multiple etiologies of cervical artery dissections have been previously reported, but the association with thyrotoxicosis is extremely rare. A previously healthy 43-year-old female presented to the emergency department with new symptoms related to thyrotoxicosis and bilateral internal carotid artery dissections. Her atrial fibrillation and hypertension resolved by treating the underlying hyperthyroidism with methimazole and propranolol. The bilateral internal carotid artery dissections were managed conservatively with acetylsalicylic acid. Despite an initially poor prognosis, the patient made a complete recovery with resolution of her neurological symptoms.

Alkaline Ethanol Oxidation Reaction on Carbon Supported Ternary PdNiBi Nanocatalyst using Modified Instant Reduction Synthesis Method.

Direct ethanol fuel cells (DEFC) still lack active and efficient electrocatalysts for the alkaline ethanol oxidation reaction (EOR). In this work, a new instant reduction synthesis method was developed to prepare carbon supported ternary PdNiBi nanocatalysts with improved EOR activity. Synthesized catalysts were characterized with a variety of structural and compositional analysis techniques in order to correlate their morphology and surface chemistry with electrochemical performance. The modified instant reduction synthesis results in well-dispersed, spherical Pd85Ni10Bi5 nanoparticles on Vulcan XC72R support (Pd85Ni10Bi5/C(II-III)), with sizes ranging from 3.7 ± 0.8 to 4.7 ± 0.7 nm. On the other hand, the common instant reduction synthesis method leads to significantly agglomerated nanoparticles (Pd85Ni10Bi5/C(I)). EOR activity and stability of these three different carbon supported PdNiBi anode catalysts with a nominal atomic ratio of 85:10:5 were probed via cyclic voltammetry and chronoamperometry using the rotating disk electrode method. Pd85Ni10Bi5/C(II) showed the highest electrocatalytic activity (150 mA⋅cm-2; 2678 mA⋅mg-1) with low onset potential (0.207 V) for EOR in alkaline medium, as compared to a commercial Pd/C and to the other synthesized ternary nanocatalysts Pd85Ni10Bi5/C(I) and Pd85Ni10Bi5/C(III). This new synthesis approach provides a new avenue to developing efficient, carbon supported ternary nanocatalysts for future energy conversion devices. Graphical AbstractThe modified instant reduction method for synthesis of ternary Pd85Ni10Bi5/C(II) nanocatalyst using Vulcan XC72R as carbon support initiates an agglomeration reduction, provides low average particle size, and enables enhanced activity for the alkaline ethanol oxidation reaction (EOR) compared to the common instant reduction method and to a commercial Pd/C catalyst.

Saline-Air Hysterosalpingo-Contrast Sonography Is Equivalent to the Modified Hysterosalpingogram Following Hysteroscopic Sterilization.

PURPOSE: To estimate the diagnostic efficacy of saline-air hysterosalpingo-contrast sonography (SA-HyCoSy) compared with the modified hysterosalpingogram (mHSG) for confirmation of both coil location and tubal occlusion following hysteroscopic sterilization. METHODS: This study included 19 women who underwent both SA-HyCoSy and mHSG where 1 test was followed by the other. Sensitivity, specificity, and positive and negative predictive values for tubal occlusion against the mHSG were calculated for each fallopian tube by 2 independent interpreters. Interrater reliability was assessed using Cohen κ statistic. Procedure time and pain level by 11-point numeric rating scale of SA-HyCoSy and mHSG were also compared. RESULTS: Thirty-eight fallopian tubes were evaluated. Tubal occlusion was noted in 97.3% of tubes for both interpreters with the mHSG compared with 92.1% and 94.7% with SA-HyCoSy. The positive and negative predictive values for tubal occlusion were 100%/100% and 50%/33%, respectively, with an overall agreement of 97.4% and 95.7%, κ = 0.48, P < 0.01. Saline-air HyCoSy changed interpretation of coil insert location in 50% and 44.7% for each interpreter, being downgraded from optimal to satisfactory in 42.9% (9/21) and 36% (9/25) and upgraded to optimal in 58.8% (10/17) and 61.5% (8/13), respectively. There were no statistically significant differences in procedural time (7.5 vs 9.4 minutes, P > 0.05) or maximum pain scores (2.3 vs 3.1, P > 0.05) for the mHSG compared with SA-HyCoSy. CONCLUSIONS: Our findings revealed a high degree of diagnostic accuracy with SA-HyCoSy for tubal occlusion, although coil location changed in nearly half of cases. Avoidance of radiation and patient convenience/compliance with SA-HyCoSy may outweigh the drawbacks.

The attitude towards disease management programs in Austrian heart failure patients: a pilot study comparing rural and urban patients.

BACKGROUND: Disease Management Programs (DMPs) for heart failure (HF) patients have been developed to better control patients' well-being as well as their daily drug intake. DMPs for HF are not always accepted by the patients, and the reasons for this phenomenon are largely unknown. We hypothesized that patients from rural areas accept a DMP more likely than patients living in a big city. Thus, a pilot study investigated differences in the attitude towards DMPs between HF-patients in one rural and one urban hospital in Austria. METHODS: Patients admitted because of HF to 2 hospitals, one with rural and one with urban populations, were included prospectively by using a questionnaire. RESULTS: Included were 60 patients, 43% females with a mean age of 76 years, in each hospital 30 patients. Rural patients were more interested in a nurse-based DMP than urban (N.=30) (P=0.029). After discharge, urban patients planned more often to attend a specialist than rural (P=0.005). No differences were found regarding gender, age, willingness to be included into a telenursing-based program and estimation of knowledge about HF. CONCLUSIONS: Structures of the health care system and patients' attitudes must be considered when planning DMPs. Development of DMPs which are accepted by urban patients will be relevant for the future.

Utility of diffusion-weighted MR imaging in the diagnosis of placenta accreta spectrum abnormality.

PURPOSE: The aim of this study was to evaluate the utility of added DWI sequences as an adjunct to traditional MR imaging in the evaluation of abnormal placentation in patients with suspicion for placenta accreta spectrum abnormality or morbidly adherent placenta (MAP). MATERIALS AND METHODS: The study was approved by local ethics committee. The subjects included pregnant women with prenatal MRI performed between July 2013 to July 2015. All imaging was performed on a Philips 1.5T MR scanner using pelvic phased-array coil. Only T2-weighted and diffusion-weighted imaging (DWI) series were compiled for review. Two randomized imaging sets were created: set 1 included T2-weighted series only (T2W); set 2 included T2W with DWI series together (T2W + DWI). Three radiologists, blinded to history and pathology, reviewed the imaging, with 2 weeks of time between the two image sets. Sensitivity, specificity, and overall accuracy for MAP were calculated and compared between T2W only and T2W + DWI reads. Associations between imaging findings and invasion on pathology were tested using the Chi-squared test. Confidence scores, inter-reader agreement, and systematic differences were documented. RESULTS: A total of 17 pregnant women were included in the study. 8 cases were pathologically diagnosed with MAP. There were no significant differences in the diagnostic accuracy between T2W and T2W + DWI in the diagnosis of MAP in terms of overall accuracy (62.7% for T2W vs. 68.6% for T2W + DWI, p = 0.68), sensitivity (70.8% for T2W vs. 95.8% for T2W + DWI, p = 0.12), and specificity (55.6% for T2W vs. 44.4% for T2W + DWI, p = 0.49). There was no significant difference in the diagnostic confidence between the review of T2W images alone and the T2W + DWI review (mean 7.3 ± 1.8 for T2W vs. 7.5 ± 1.8 for T2W + DWI, p = 0.37). CONCLUSION: With the current imaging technique, addition of DWI sequence to the traditional T2W images cannot be shown to significantly increase the accuracy or reader confidence for diagnosis of placenta accreta spectrum abnormality. However, DWI does improve identification of abnormalities in the placental-myometrial interface.

How to Integrate Cell-Free DNA Screening With Sonographic Markers for Aneuploidy: An Update.

OBJECTIVE: The sonologist detects a so-called "soft marker" during approximately 10% of routine second-trimester anatomy examinations and is often uncertain about what further management is appropriate. This article will specifically address the management of patients with sonographic markers for six common entities: choroid plexus cysts (CPCs), ventriculomegaly (VM), echogenic intracardiac focus (EIF), urinary tract dilation (UTD), fetal echogenic bowel (FEB), and femoral and humeral shortening. The use of cell-free DNA screening and its relationship to these sonographic findings will be reviewed. CONCLUSION: The era of ultrasound markers as a screen for fetal aneuploidy is coming to a close. The detection of these markers on an ultrasound examination should simply serve as a reminder to ensure that the patient was offered cell-free DNA screening or conventional analyte screening. Cell-free DNA testing is revolutionizing screening. With normal results on a cell-free DNA test, many isolated soft markers-including CPCs, EIF, mild rhizomelic limb shortening, and mild pyelectasis-are irrelevant from a genetic standpoint. However, further counseling and workup are indicated for VM, true FEB, femur or humerus length measurement that is less than 2.5-percentile value, and pyelectasis to evaluate for the nongenetic associations with these findings. Finally, cell-free DNA testing is currently a screening test; positive results require definitive diagnostic testing with amniocentesis or chorionic villus sampling.

Iopamidol as an oral contrast media for computed tomography: a taste comparison to iohexol, diatrizoate sodium, and barium sulfate.

OBJECTIVES: The objective of this study is to compare the palatability of iopamidol and iohexol. METHODS: This was a blinded and randomized trial in which fifty healthy subjects taste tested iopamidol (Isovue, Bracco Diagnostics), iohexol (Omnipaque, GE Healthcare), diatrizoate meglumine and diatrizoate sodium solution (Gastrografin, Bracco Diagnostics), and barium sulfate suspension 2.1% w/v, 2.0% w/w (READI-CAT2, E-Z-EM). Participants scored palatability on a continuous scale from 0 to 40 (0 = intolerable, 10 = unpleasant but tolerable, 20 = neutral, 30 = kind of like, 40 = strongly like). RESULTS: Mean scores (SD/SEM) for the contrast agents (n = 50) were iopamidol = 21.0 (8.4/1.2); iohexol = 21.8 (7.1/1.0); Gastrografin = 16.8 (9.6/1.4); and barium = 23.7 (9.1/1.3). One-way ANOVA equality of means test shows rejection of the hypothesis that the means are equal (F* = 6.550, p = .000). Post hoc testing demonstrates Gastrografin to be significantly less preferred to barium (p = .000) and iohexol (p = .012). No difference was found between iopamidol and iohexol (p = .959). One-way ANOVA equality of means test of just iopamidol, iohexol, and barium does not reject the hypothesis that means are equal (F* = 1.778 and p = .174). CONCLUSION: There is no significant difference in palatability between iopamidol and iohexol, supporting the use of iopamidol as a viable alternative to iohexol as an oral contrast agent.

Torsed Ovarian Dermoid.

Ovarian dermoids constitute the most common ovarian neoplasm and make up approximately 20% of all ovarian neoplasms. Dermoids are most common in the reproductive age group, but unlike other ovarian germ cell tumors, their age distribution is quite broad. Torsion may occur in approximately 15% of cases and is more common during pregnancy and in the 6 weeks immediately after delivery. We present a 17-year-old who came to the emergency department in her puerperium with severe right lower quadrant pain. The diagnosis of a 12-cm dermoid was missed at ultrasound. We discuss the reasons for the mistake on ultrasound and give strategies to prevent this from happening in the future. Three commonly overlooked teaching points regarding dermoids are discussed. Ultrasound and computed tomographic imaging, operative course, and correlative intraoperative and pathological images are presented.
