Ultrasonographic ovarian mass scoring system for predicting malignancy in pregnant women with ovarian mass

During routine antenatal ultrasound examinations, an ovarian mass can be found incidentally. In clinical practice, the differential diagnosis between benign and malignant ovarian masses is essential for planning further management. Ultrasound imaging has become the most popular diagnostic tool during pregnancy, with the recent development of ultrasonography. In non-pregnant women, several methods have been used to predict malignant ovarian masses before surgery. The International Ovarian Tumor Analysis (IOTA) group reported several scoring systems, such as the IOTA simple rules, IOTA logistic regression models, and IOTA assessment of different NEoplasias in the adneXa. Other researchers have also evaluated the malignancy of ovarian masses before surgery using scoring systems such as the Sassone score, pelvic mass score, DePriest score, Lerner score, and Ovarian-Adnexal Reporting and Data System. These researchers suggested specific features of ovarian masses that can be used for differential diagnosis, including size, proportion of solid tissue, papillary projections, inner wall structure, locules, wall thickness, septa, echogenicity, acoustic shadows, and presence of ascites. Although these factors can also be measured in pregnant women using ultrasound, only a few studies have applied ovarian scoring systems in pregnant women. In this article, we reviewed various scoring systems for predicting malignant tumors of the ovary and determined whether they can be applied to pregnant women.

Effects of Preoperative Autologous Blood Donation in Patients Undergoing Minimally Invasive Cardiac Surgery / 대한흉부외과학회지

BACKGROUND: Preoperative autologous blood donation (PABD) is a conservation strategy for reducing allogenic blood transfusion (ABT) during minimally invasive cardiac surgery (MICS). We aimed to evaluate the effects of PABD on the frequency of ABT and clinical outcomes in patients undergoing MICS.METHODS: We enrolled 113 patients (47.8±13.1 years, 50 men) undergoing MICS without preoperative anemia (hemoglobin >11 g/dL) between 2014 and 2017. Of these patients, 69 (the PABD group) donated autologous blood preoperatively and were compared to the non-PABD group (n=44). We analyzed the frequency of perioperative ABT and clinical outcomes.RESULTS: Baseline characteristics did not significantly differ between groups, although preoperative hemoglobin levels were lower in the PABD group. All operations were performed using a minimally invasive approach. Patients’ surgical profiles were similar. There were no cases of mortality or significant differences in early postoperative outcomes. During the early postoperative period, hemoglobin levels were higher in the PABD group. No significant difference was found in the frequency of ABT.CONCLUSION: Although the PABD group had higher postoperative hemoglobin levels, there was no clear clinical benefit in the early postoperative period, despite a great deal of effort and additional cost. Additional PABD in the setting of strict policies for blood conservation was ineffective in reducing ABT for young and relatively healthy patients who underwent MICS.

Correlation between Vascular Compliance and Increase of Blood Pressure on Exercising in Normotensive Group

BACKGROUND AND OBJECTIVES: Vascular compliance is known to be decreased in hypertension, even at an early stage. The blood pressure response to exercise reflects the future risk of developing hypertension. A study was performed on the relationship between the vascular compliance and blood pressure response to exercise, to evaluate whether the vascular compliance is decreased in normotensive persons with a relatively higher future risk of developing hypertension. SUBJECTS AND METHODS: The subjects of the study were adults with normal blood pressure (SBP<120 mmHg, DBP<80 mmHg), who had undergone health screening and both echocardiography and treadmill test. Those patients with a history of diabetes mellitus or clinical cardiovascular diseases were excluded form the subjects. An index of overall vascular compliance (SVI/PP) was calculated using echocardiography. The relationship between the peak systolic blood pressure during exercise and vascular compliance was also investigated. RESULTS: The subjects were 77 patients, 54 male and 23 female, with a mean age of 47.6+/-7.7 years. The measured vascular compliance and average of peak systolic pressure on exercising were 1.08+/-0.24 L/m2/mmHg and 154+/-21 mmHg, respectively. The peak systolic pressure was correlated with the vascular compliance (r=-0.24, p<0.05). The peak systolic pressure at stage 3 was also correlated with the vascular compliance (r=-0.24, p<0.05). This relationship persisted after adjustment for age, gender, basal systolic blood pressure and maximal oxygen consumption (p<0.05). CONCLUSION: The vascular compliance was lower in subjects with a larger increase in blood pressure during exercise whose basal blood pressure was even below 120/80 mmHg. This finding may suggest that a decreased vascular compliance precedes the changes of hypertension. A longitudinal follow-up study is warranted.
