A survey of contraceptive method use among patients with delayed permanent contraception due to the COVID-19 pandemic.

OBJECTIVES: Evaluate contraception usage in patients awaiting permanent contraception during COVID-19 pandemic. STUDY DESIGN: Patients awaiting permanent contraception between March 2020 and July 2022 completed a survey assessing contraceptive usage. Descriptive statistics were analyzed. RESULTS: One hundred and twenty-three patients consented to the survey. Ninety seven percent identified as Black, Indigenous, and people of color. Eighty three percent used alternative forms of contraception, with 31% using long acting, reversible contraceptives. Eighty nine percent still desired surgery. CONCLUSIONS: Despite delays, most patients still desired surgery. Patients alternatively chose intrauterine devices and implants. IMPLICATIONS: Hospitals should prioritize permanent contraception to avoid delays in access to desired reproductive healthcare options.

Dose-Dense Chemotherapy Regimen for Breast Cancer Associated with Significant Decline in Ovarian Reserve.

Purpose: To determine the impact of dose-dense chemotherapy administration on ovarian reserve in women undergoing treatment for breast cancer. Patients and Methods: We conducted a retrospective cohort study of reproductive age women who underwent dose-dense chemotherapy regimens with doxorubicin hydrochloride and cyclophosphamide with or without paclitaxel for a new diagnosis of breast cancer. We compared pre- and post-treatment serum antimullerian hormone (AMH) levels and assessed changes in AMH over time. Results: Fifty-seven patients met inclusion criteria. Median pre-treatment AMH was 2.9 ng/mL, whereas post-treatment AMH was 0.1 ng/mL, demonstrating a dramatic reduction in AMH levels after treatment with a dose-dense regimen. This change was independent of age and was sustained over 12 months from treatment completion. Conclusions: Dose-dense chemotherapy regimens for breast cancer lead to marked and sustained decreases in AMH irrespective of patient age.

Umbilical cord gas analysis: clinical implications of a comprehensive, contemporary determination of normal ranges.

BACKGROUND: Umbilical cord gases are often used to assess the impact of labor and delivery on the fetus. However, no large series exists that reflects contemporary obstetrical practice or that analyzed blood gas ranges by route of delivery. Baseline, prelabor acid-base status in the human fetus is also poorly defined, rendering the assessment of blood gas changes during labor difficult. OBJECTIVE: This study aimed to define normal umbilical cord gas and lactate values, stratified by mode of delivery, in a large contemporary series in which universal umbilical cord gas evaluation was dictated by protocol. STUDY DESIGN: This was a retrospective cohort study. We analyzed the umbilical cord gas and lactate data of an unselected population of infants born between March 2012 and April 2022 at a large teaching hospital. These values were then analyzed by mode of delivery and, for cesarean deliveries, by indication for cesarean delivery and type of anesthesia. Umbilical cord gas values from infants delivered by elective cesarean delivey under general anesthesia without labor were considered representative of baseline, prelabor values. RESULTS: Data were available for 45,475 infants. The median arterial pH values and interquartile ranges for vaginal births, elective cesarean deliveries without labor, and cesarean deliveries performed for fetal heart rate concerns were 7.27 (0.09), 7.27 (0.06), and 7.25 (0.09), respectively. Arterial lactate values for these same 3 groups were 4.1 (2.5), 2.5 (1.2), and 4.0 (2.8) mmoles/L, respectively. Because of the very large sample size, most comparisons yielded differences that were statistically significant, but clinically irrelevant. Of all the infants, 14% had an arterial pH <7.20; a pH value of 7.1 represents 2 standard deviations from the mean. CONCLUSION: This large, population-based study of umbilical cord gas and lactate levels in an unselected population, stratified by delivery mode, represents a previously unavailable benchmark for the evaluation of umbilical cord gases. Arterial umbilical cord pH values for infants delivered by elective caesarean delivery without labor (median pH 7.28) reflect a lower prelabor fetal pH baseline than previously assumed. This finding, coupled with our determination that a 2 standard deviation below normal pH limit of 7.1, instead of the historic arbitrary pH of 7.2 threshold, helps to explain the poor positive predictive value of electronic fetal heart rate monitoring, a test designed to detect arterial pH levels that have fallen from an assumed baseline near pH 7.4 to an assumed potentially injurious pH level of <7.2. Uncomplicated labor, even when prolonged, does not generally lead to a clinically significant cumulative hypoxic stress to the human fetus. These findings, along with our determination that there is no difference in the acid-base status among infants delivered by cesarean delivery for fetal heart rate concerns, help to explain the failure of current approaches in labor and delivery management to reduce the rates of neonatal hypoxic-ischemic encephalopathy and cerebral palsy, conditions that almost always reflect developmental events rather than the effects of labor on the fetus.

Improved Identification of Adolescent Hip Dysplasia Using a Screening Method Based on Lateral Center Edge Angle Measurements.

BACKGROUND: In addition to the clinical exam, several quantitative measurement tools are performed on pelvic radiographs in the assessment of adolescent hip dysplasia at most dedicated pediatric hip preservation clinics, with the most commonly used measurement called the lateral center edge angle (LCEA). However, most pediatric radiologists do not use these quantitative measuring tools and instead make the diagnosis of adolescent hip dysplasia based on subjective review. OBJECTIVE: The purpose of this study is to determine the additive value of a measurement-based diagnosis of adolescent hip dysplasia using LCEA versus subjective radiographic interpretation by pediatric radiologists. METHODS: A review of pelvic radiographs for the binomial diagnosis of hip dysplasia was performed by four pediatric radiologists (two general, two musculoskeletal). The review included 97 pelvic AP radiographs (mean age 14.4 years [range 10-20 years], 81% female) for a total of 194 hips (58 cases of adolescent hip dysplasia and 136 normal) all of whom were evaluated in a tertiary care pediatric subspecialty hip preservation clinic. Subjective radiographic interpretation of each hip for a binomial diagnosis of hip dysplasia was performed. 2 weeks later and without knowledge of the subjective radiographic interpretation results, the same review was performed with LCEA measurement and a diagnosis of hip dysplasia made when LCEA angles were under 18 degrees. A comparison of sensitivity/specificity between methods per reader was conducted. A comparison of accuracy between methods for all readers combined was performed. RESULTS: For all four reviewers, the sensitivity of subjective versus LCEA measurement-based diagnosis of hip dysplasia was 54-67% (average 58%) versus 64-72% (average 67%), respectively, and specificity was 87-95% (average 90%) versus 89-94% (average 92%), respectively. All four readers demonstrated an intra-reader trend for improvement in the diagnosis of adolescent hip dysplasia after the addition of LCEA measurements but was only statistically significant in one of the four readers. The combined accuracy of all four readers for subjective and LCEA measurement-based interpretation was 81% and 85%, respectively with p = 0.006. CONCLUSION: Compared with subjective interpretation, LCEA measurements demonstrate increased diagnostic accuracy amongst pediatric radiologists for the correct diagnosis of adolescent hip dysplasia.

Fetal sex and the development of gestational diabetes mellitus in polycystic ovarian syndrome gravidae.

BACKGROUND: Polycystic ovarian syndrome is characterized by elevated androgens and is a well-known risk factor for the occurrence of gestational diabetes mellitus. Androgens (particularly dehydroepiandrosterone-sulfate) are crucial for the development and characteristics of the male reproductive tract during fetal life, and fetal dehydroepiandrosterone-sulfate enters the placenta where it is metabolized and functions as an estrogen substrate. Given this unique sex-specific relationship with androgens and the association of serum dehydroepiandrosterone-sulfate concentration with insulin resistance, we hypothesized that metabolic comorbidities in pregnancy might differ by fetal sex in gravidae with polycystic ovarian syndrome, notably in those with infertility. OBJECTIVE: This study aimed to evaluate the data in a large population-based database to explore if fetal sex was significantly associated with gestational diabetes mellitus in gravidae with infertility and polycystic ovarian syndrome after controlling for confounders. STUDY DESIGN: This study was designed to evaluate the risk for the occurrence and rates of gestational diabetes mellitus among gravidae with infertility and a history of polycystic ovarian syndrome. We used a 2-hospital, single academic institution database comprising more than 30,000 subjects enrolled from September 2011 to June 2021 to identify all gravidae with diagnoses of infertility and polycystic ovarian syndrome at the time of delivery and to compare them with gravidae who lacked these comorbidities. Data on covariates, including but not limited to maternal age, body mass index, fetal sex, race, ethnicity, presence or absence of hypertensive disease, and presence or absence of gestational diabetes were identified. Unadjusted and adjusted odds rations were calculated. RESULTS: We found a statistically significant association between fetal female sex and the development of gestational diabetes mellitus in gravidae with polycystic ovarian syndrome (odds ratio for female vs male, 2.13; 95% confidence interval, 1.06-4.32; P=.03). After adjusting for potential confounders identified in our univariate analyses, there continued to be a statistically significant association between female fetuses and the development of gestational diabetes mellitus (adjusted odds ratio for female vs male, 2.10; 95% confidence interval, 1.04-4.41; P=.04). In contrast, there was no significant association between fetal sex and the development of gestational diabetes mellitus in our similar analysis of gravidae without infertility and polycystic ovarian syndrome (P=.99). CONCLUSION: Although the origin of gestational diabetes mellitus is multifactorial, we found that female fetal sex is associated with gestational diabetes mellitus in gravidae with infertility and polycystic ovarian syndrome but not in their comparative controls. Further research on the molecular mechanisms driving the association between female fetuses and the development of gestational diabetes mellitus in the context of maternal polycystic ovarian syndrome is warranted.

Obstetric outcomes after fetal intervention - a single-center descriptive review.

BACKGROUND: Advancements in fetal interventions have enabled in utero management of several fetal congenital anomalies and conditions; these are accomplished via ultrasound-guided, fetoscopic or open techniques. Understanding the risk of preterm labor associated with each technique is critical for patient counseling and choice of intervention; however, data on obstetrical outcomes associated with each type of intervention remains limited. OBJECTIVE: To provide descriptive information on the risk of preterm birth following fetal intervention, based on underlying disease and procedure performed. STUDY DESIGN: This is a retrospective cohort study of patients who underwent fetal intervention at our institution between 1 October 2016 and 31 December 2019. Interventions were stratified into three groups- ultrasound-guided, fetoscopic and open procedures. Procedures included fetoscopic laser ablation (FLA) for twin-to-twin transfusion syndrome (TTTS), fetoscopic endotracheal occlusion (FETO) for congenital diaphragmatic hernia (CDH), vesicoamniotic shunt (VAS) for lower urinary tract obstruction (LUTO), fetal cystoscopy for LUTO, and open and fetoscopic myelomeningocele repair. The primary outcomes were gestational age at delivery and frequency of premature rupture of the membranes. RESULTS: Sixty-eight patients were included; 20 (29.4%) underwent ultrasound- guided procedures, 37 (54.4%) underwent fetoscopy, and 11 (16.2%) open in utero intervention. The diagnoses and type of intervention within each group were different. The mean gestational age (GA) ± standard deviation (SD) at intervention for ultrasound- guided, fetoscopic, open procedures were 24.1 ± 4.4 weeks, 22.8 ± 3.7 weeks, and 25.0 ± 0.9 weeks, respectively. The mean GA ± SD at delivery were 31.9 ± 4.9 weeks, 31.6 ± 4.6 weeks, and 32.6 ± 5.5 weeks, respectively. The mean interval from time of intervention to delivery were 54 ± 39, 62 ± 37 and 55 ± 36 days, respectively (p = 0.82); and the risk of PPROM was 26.3%, 21.6% and 27.3%, respectively. The mean GA at delivery and the frequency of PPROM were different for each specific disease that was treated. CONCLUSION: The risk of preterm birth and PPROM following fetal intervention with different procedures, categorized under ultrasound- guided, fetoscopic and open fetal interventions at our institution were similar amongst the three groups, but they were different depending on the diagnosis of the treated anomaly.

Postoperative opioid use for patients with chronic pelvic pain undergoing robotic surgery for resection of endometriosis.

We aimed to identify the amount of opioids used in the postoperative setting for patients with a history of chronic pelvic pain undergoing robotic surgical excision of endometriosis and compare this to patients undergoing benign robotic gynecologic surgery for other indications. We conducted a retrospective cohort study in an urban academic university hospital from January 2019 to March 2020. Data regarding opioid use was collected via a patient-reported survey that was given at the 3 weeks follow-up visit. Data regarding opioid use was compared to patients undergoing robotic surgery for other benign gynecologic indications. Our study included 158 patients, 119 undergoing surgery for endometriosis and 39 patients undergoing robotic surgery for other benign gynecologic indications. Patients undergoing surgery for endometriosis used on average 105.9 morphine milligram equivalents (MME), equivalent to 14 tabs of oxycodone 5 mg. There was no statistically significant difference in the amount of opioids used postoperatively based on stage of endometriosis or need for hysterectomy. Patients undergoing surgery for other benign indications used on average 49.4 MME, equivalent to 6 tabs of oxycodone 5 mg. The difference in amount of opioids used between patients with and without endometriosis was statistically significant. In conclusion, patients undergoing robotic surgery for endometriosis used over two times as many opioids postoperatively as patients without endometriosis and have a higher perceived postoperative pain. Providers should be aware of this difference in order to provide better pain control for this patient population.

Disparities between US Hispanic and non-Hispanic women in obesity-related perinatal outcomes: a prospective cohort study.

BACKGROUND: Mortality figures and national health surveillance data have demonstrated that Hispanics have a 24% lower risk of all-cause mortality compared to their non-Hispanic counterparts despite increased rates of obesity and related illnesses. OBJECTIVE: The aim of this study is to evaluate if this paradox exists for obesity-related perinatal outcomes in otherwise low-risk Hispanic women. MATERIALS AND METHODS: A prospective cohort study of low-risk women across all BMI classes with a singleton, non-anomalous term pregnancy admitted in active labor or undergoing induction of labor between May 2014 and April 2017. All demographic, obstetric, and neonatal outcomes were recorded, and the body mass index (BMI) closest to delivery was used for analysis. Data including composites of adverse maternal and neonatal outcomes were compared across BMI classes and between individuals of Hispanic and non-Hispanic ethnicity. Women with antenatal complications, prior cesarean delivery, and cesarean for non-reassuring fetal status were excluded. RESULTS: Of the 11,369 women who met inclusion criteria, 6303 (55%) were Hispanic. Eight percent of Hispanic women were normal weight (BMI: 18.5-24.9), 34% were overweight (BMI: 25-29.9), and 58% were obese (BMI > 30). Fourteen percent of non-Hispanic women were normal weight, 42% were overweight, and 44% were obese. The majority (65%) of women were multiparous. Rate of induction and birthweight increased across BMI for Hispanic and non-Hispanic groups, however the route of delivery was not significantly different (p = .22, 0.16, respectively). Although the association between BMI and composite perinatal complications did not differ by BMI class and ethnicity, the newborns of non-Hispanic women were more likely to be admitted to the neonatal intensive care unit with increasing maternal weight class (<0.001), even after adjusting for age, parity, marital status, prenatal visits, current tobacco use, type of labor, mode of delivery, and birthweight. CONCLUSION: There were no demonstrable differences in composite adverse maternal or neonatal outcomes between Hispanic and non-Hispanic obese women. However, newborns of non-Hispanic obese women were more likely to be transferred to the neonatal intensive care unit with increasing maternal BMI.

Acute appendicitis and SARS-CoV-2 in children: imaging findings at a tertiary children's hospital during the COVID-19 pandemic.

BACKGROUND: Evidence suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may be associated with appendicitis or clinical symptoms that mimic appendicitis, but it is not clear if the findings or utility of imaging in pediatric patients with suspected appendicitis have changed since the onset of the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: To evaluate for potential differences in SARS-CoV-2 positive and SARS-CoV-2 negative pediatric patients imaged for suspected appendicitis to determine the reliability of the existing medical imaging approach for appendicitis in a population that contains both SARS-CoV-2 positive and SARS-CoV-2 negative pediatric patients. MATERIALS AND METHODS: Patients imaged for suspected appendicitis Apr. 1, 2020, to Dec. 31, 2020, were identified via an electronic medical records search. Differences in ultrasound (US) diagnostic performance, use of computed tomography (CT) following US, rates of appendicitis, imaging findings of appendicitis and perforation were compared between SARS-CoV-2 positive and SARS-CoV-2 negative tested patients, using pathology and surgery as reference standards for appendicitis and perforation, respectively. Fisher exact test and Student's t-test were used for statistical analysis. RESULTS: One thousand, six hundred and ninety-three patients < 18 years old met inclusion criteria, with 46% (772/1,693) female, 11 imaged with only CT and 1,682 with US. Comparing SARS-CoV-2 positive and SARS-CoV-2 negative patients, no statistically significant differences in sensitivity or specificity of US (P = 1 and P = 1, respectively), or in the US (P-values ranging from 0.1 to 1.0) or CT imaging findings (P-values ranging from 0.2 to 1.0) in appendicitis were found. Perforation rates were similar between SARS-CoV-2 positive (20/57, 35.1% perforated) and SARS-CoV-2 negative (359/785, 45.7% perforated) patients with appendicitis (P = 0.13). Use of CT following first-line US was similar, with 7/125 (5.6%) of SARS-CoV-2 positive imaged with CT after US and 127/1,557 (8.2%) of SARS-CoV-2 negative imaged with CT after US (P = 0.39). CONCLUSION: In pediatric patients with suspected appendicitis, no significant difference was found in the diagnostic performance of US, CT usage or perforation rates between SARS-CoV-2 positive and SARS-CoV-2 negative patients.

Clinical characteristics and outcomes of combined thrombolysis and anticoagulation for pediatric and young adult lower extremity and inferior vena cava thrombosis.

Effective treatment for acute, extensive, symptomatic lower extremity (LE) thrombosis involves thrombolysis in addition to anticoagulation. There is limited available data on the outcomes and safety of thrombolysis to help guide its use in pediatrics and young adults. A retrospective study of children and young adults (<21 years of age) that received catheter directed thrombolysis (CDT) for LE and inferior vena cava (IVC) thrombosis was performed over a 5-year span at a pediatric tertiary care center. A total of 29 patients were identified for inclusion in the study, 76% (n = 22) received overnight CDT while 24% (n = 7) received tissue plasminogen activator as a bolus dose during a single interventional procedure. The median age of the cohort was 15.8 years (range 0-19.1). All patients were treated with a course of therapeutic anticoagulation. The thromboses represented were extensive, with 93% (n = 27) being occlusive and affecting multiple venous segments. Thrombus resolution occurred in 35% (n = 10) of patients. Rivaroxaban use (p < 0.01) during the course of anticoagulation and estrogen-containing hormonal therapy (p = 0.01) use prior to diagnosis were associated with thrombus resolution, while Hispanic ethnicity (p = 0.06) had a trend toward thrombus persistence. There were one major and 3 minor bleeding events that occurred as complications of thrombolysis and no treatment related deaths. This study provides baseline information that can be used to help guide clinicians treating similar patients and suggests the need to develop an improved, uniform treatment approach for superior resolution rates.

Usefulness of Exam Questions and Vital Signs for Predicting the Outcome of Objective Vestibular Tests.

OBJECTIVES/HYPOTHESIS: To determine the value of standard clinic screening questions and vital signs in predicting abnormal vestibular function, indicated by standard objective diagnostic tests. STUDY DESIGN: Retrospective records review. METHODS: We reviewed electronic medical records of 150 patients seen by the neurotologists or the physician assistant they supervised, in an out-patient tertiary care clinic, between June 2018 and March 2020, and subsequently referred for the complete objective vestibular test battery (VB). RESULTS: Of standard questions asked during the initial exam about vertigo, disequilibrium, lightheadedness and oscillopsia, only vertigo predicted an abnormal response on the VB. More males than females had abnormal VB responses, P < .05. Pulse was not related to VB score. Significantly more subjects with blood pressure in the range for stage 2 hypertension (blood pressure [BP] stage 2) had abnormal than normal results on the VB, P < .00001. Subjects with BP stage 2 had high rates of diabetes (34.2%) and hypertension (68.4%) as diagnosed by their primary care physicians or cardiologists. CONCLUSION: Complaints of subjective vertigo and BP in the range of hypertension stage 2 are most likely to predict abnormal findings on the VB. Therefore, during an examination of a patient who comes in complaining of dizziness, two measures may be the most useful for screening: BP in the range of hypertension type 2, when BP is taken by a nurse, and a question to determine whether or not the patient has true vertigo. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:1382-1385, 2021.

Incomplete Records as a Leading Cause of Missed Opportunity for Human Papillomavirus Vaccine Initiation in a Safety Net Health System.

OBJECTIVE: The goal of this study was to categorize reasons behind missed opportunities for human papillomavirus (HPV) vaccine initiation in an under-resourced population and to identify associated patient and clinic characteristics. METHODS: Manual chart review was performed for patients aged 11 to 18 years who visited a primary care clinic in a health system in Texas, USA between 06/01/18 and 08/31/18 and were due for an initial HPV vaccine dose but did not receive it. Reasons for HPV vaccine noninitiation were categorized as follows: incomplete immunization record, no documentation of discussion (no documentation that the HPV vaccine was offered or ordered), refusal, staff/provider error, and medical. Multinomial logistic regression was used to examine factors associated with each category. RESULTS: Of 4467 adolescents seen in the study period, 575 (12.9%) were due for the first dose of HPV vaccine but did not receive it. The most common reason for noninitiation was incomplete immunization record (37%), followed by no documentation of discussion (24%), refusal (20%), staff/provider error (15%), and medical (4%). The highest odds of incomplete immunization were among older adolescents. The highest odds of no documentation of discussion were during sick visits. The highest odds of staff/provider error were among patients with commercial insurance. The lowest odds of refusal were in patients with county/indigent insurance. CONCLUSIONS: The most common reason for missed opportunity visits for HPV vaccine initiation was lack of adequate immunization records. Our study highlights the importance of immunization record access and bidirectional reporting as important targets for future interventions.

Prediction of Functional Limitations in Balance after Tests of Tandem Walking and Standing Balance in Older Adults.

OBJECTIVE: Older adults who may not complain of balance problems may nevertheless be developing subtle balance problems that may affect future functioning. This study sought to determine whether subtle problems could be predicted by standard balance testing. METHODS: At the geriatric medicine clinic at an academic tertiary-care center, geriatricians referred 27 people who were ambulatory without gait aids and had no apparent neurologic or musculoskeletal impairments affecting their balance or gait performance. Initially, subjects were screened with some questions about vertigo, tests of standing balance on foam with eyes closed (Romberg tests) with head still, and head nodding (pitch) and shaking (yaw) at 0.3 Hz, and tandem walking with eyes closed (TW). Approximately 2 years later, 22 subjects were available to be rescreened. RESULTS: At the second test date subjects' scores declined slightly but significantly on all three variations of the Romberg tests: with head still, head pitch, and head yaw, P ≥ 0.02, but TW did not change significantly. TW was the best predictor of balance performance; the lowest-scoring subjects at the second test used a cane, had undergone hip surgery, or were scheduled for hip surgery: sensitivity 1.0, specificity 0.84. The second-best predictor was Romberg on foam with eyes closed and head still. CONCLUSIONS: The data suggest that some older adults may have subtle musculoskeletal impairments that may be indicated by simple balance tests. A finding on these tests may indicate the need for further workup for balance-related problems. These quick, inexpensive tests can be administered by ancillary staff and may add important information to the initial visit and annual follow-up visits.

Paratubal Cyst Recurrence in Children and Adolescents.

STUDY OBJECTIVE: To examine the association between patient characteristics and risk for recurrence risk of paratubal cysts (PTC) in children and adolescents. DESIGN: Retrospective chart review at a single institution. SETTING: Single academic children's hospital. PARTICIPANTS: Pediatric patients presenting to Texas Children's Hospital between July 2007 and March 2019. Patients were identified for the study by reviewing pathology reports and were included if they met inclusion criteria of a pathologic diagnosis of a paratubal or paraovarian cyst removed during any surgical procedure between July 2007 and March 2019. INTERVENTIONS: Subjects with pathologic diagnoses of a paratubal cyst during the study period underwent chart review for the following data points: age at presentation, ethnicity, pathologic recurrence of paratubal cysts, pubertal status, body mass index (BMI), diagnosis of polycystic ovary syndrome (PCOS), size of cyst, laterality of cysts, and number of cysts. MAIN OUTCOME MEASURE(S): Recurrence, Pathology types. RESULTS: Of the 627 patients that met inclusion criteria, the incidence of recurrence was 11.3%. Group 1 included those with recurrence of PTC (N = 70). Group 2 was identified as those without recurrence of PTC (N = 557). There were no differences related to age, BMI, ethnicity, history of PCOS, cyst size, laterality or number of cysts present. PTC NOS and serous PTC occurred most frequently. Of the unique cases involving recurrence, 70.1% recurred on the ipsilateral side. There were no cases of paratubal cyst malignancies in this cohort. The range of pathology diagnoses included pathologies that may occur in ovarian cysts. This is particularly interesting, given the known origins of ovarian cancer from fallopian tube transformations. Rare pathology diagnoses likely did not occur with frequency to determine definitive risks of recurrence in these cases. CONCLUSIONS: There appears to be a baseline recurrence risk for PTC, for which patients can be counseled. Recurrence does not appear to be associated with any particular pathology type, cyst size, number of cysts, BMI, PCOS, or puberty stage. Recurrence, should it occur, appears to occur more commonly on the ipsilateral side.

Predictors of Urinary Retention After Vesicovaginal Fistula Surgery: A Retrospective Case-Control Study.

OBJECTIVE: The objective of this study is to determine the predictors for urinary retention after vesicovaginal fistula surgery. METHODS: This was a retrospective case-control study of women who underwent vesicovaginal fistula repair between January 2014 and December 2017 at the Fistula Care Centre in Lilongwe, Malawi. Cases were defined as patients with documented urinary retention, defined as a postvoid residual that is 50% greater than the total void of at least 100 mL. The cases and controls were matched by the 3 components of the Goh classification system in a ratio of 1:5. Univariate analysis was used to detect differences between demographic, clinical characteristics, and operative techniques between cases and control. Logistic regression analysis was performed for estimation of odds ratios (ORs). RESULTS: There were no statistically significant differences between the 40 cases and 187 controls, when comparing age, gravidity, parity, body mass index, and length of postoperative catheterization. The median amount of postvoid residual noted at the time of diagnosis was 240 mL (range, 55-927 mL). Odds for urinary retention was 3 times higher among those with vertical closure than patients with horizontal closure of the bladder (OR, 2.91; 95% confidence interval, 1.35-6.20). Patients with prior fistula repairs were significantly less likely to develop urinary retention compared to those receiving surgery for the first time (OR, 0.27; 95% confidence interval, 0.10-0.67). CONCLUSIONS: Vertical closure of the bladder and patients without a history of prior fistula repairs are predictors for developing urinary retention after fistula repair surgery.

Adnexal Torsion in Children and Adolescents: A Retrospective Review of 245 Cases at a Single Institution.

STUDY OBJECTIVE: Adnexal torsion (AT) requires urgent surgical intervention to preserve ovarian function. Historically, treatment for AT was oophorectomy because of concerns related to leaving a nonviable ischemic ovary. No published studies support these theoretical concerns and current literature supports conservative management. The aim of this study was to review the institutional outcomes for AT cases, including salvage rates and complications. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was approved by the institutional review board at Baylor College of Medicine. A retrospective chart review on cases of AT from 2007 to 2016 at a single Children's hospital was performed on the basis of International Classification of Diseases, 10th revision and Current Procedural Terminology codes. A standardized chart review form was used in data extraction. Statistical analysis was performed using SAS version 9.4 (SAS Institute). RESULTS: Chart review identified 245 torsion cases in 237 patients. The mean age was 12.4 ± 3.29 years. Of the participants, 230 (94%) underwent minimally invasive laparoscopy with ovarian preservation in 233 (95%) of the cases. There were no complications due to detorsion of the affected adnexa. Intraoperatively, the right adnexa was affected in 134 (55%) cases and a lesion was noted in 193 (79%) cases, most commonly paratubal cysts and mature teratomas. The malignancy rate was low, noted only in 4/245 patients at (1.2%). Pediatric gynecology performed most of the cases (n = 214; 87%). CONCLUSION: The findings of our study continue to support the conservative management of patients with AT.

Vision Screening in Adults Across the Life Span.

OBJECTIVES: The goal of this study was to determine whether adults across the life span differ in responses to quick vision screening and how those responses relate to adults' use of specialized eye care. METHODS: Subjects were 363 community-dwelling ambulatory adults, 21 to 95 years old, who were tested while they wore their corrective lenses during routine visits to a tertiary care facility. No subjects had known neurological impairments, age-related macular degeneration, or other significant eye disease. A wall-mounted Early Treatment in Diabetic Retinopathy Study chart was used. RESULTS: Older adults 58 years old or older had significantly worse scores than younger adults. Scores did not differ between subjects who had been tested within or prior to the last 10 months. Older subjects had their vision tested significantly more recently than younger subjects. CONCLUSIONS: Vision screening is quick, inexpensive, and easily performed by ancillary staff, and it may provide the physician with useful additional information for treatment planning.

Low-fat Dietary Pattern and Pancreatic Cancer Risk in the Women's Health Initiative Dietary Modification Randomized Controlled Trial.

Background: Observational studies suggest that diet may influence pancreatic cancer risk. We investigated the effect of a low-fat dietary intervention on pancreatic cancer incidence. Methods: The Women's Health Initiative Dietary Modification (WHI-DM) trial is a randomized controlled trial conducted in 48 835 postmenopausal women age 50 to 79 years in the United States between 1993 and 1998. Women were randomly assigned to the intervention group (n = 19 541), with the goal of reducing total fat intake and increasing intake of vegetables, fruits, and grains, or to the usual diet comparison group (n = 29 294). The intervention concluded in March 2005. We evaluated the effect of the intervention on pancreatic cancer incidence with the follow-up through 2014 using the log-rank test and multivariable Cox proportional hazards regression model. All statistical tests were two-sided. Results: In intention-to-treat analyses including 46 200 women, 92 vs 165 pancreatic cancer cases were ascertained in the intervention vs the comparison group (P = .23). The multivariable hazard ratio (HR) of pancreatic cancer was 0.86 (95% confidence interval [CI] = 0.67 to 1.11). Risk was statistically significantly reduced among women with baseline body mass indexes (BMIs) of 25 kg/m2 or higher (HR = 0.71, 95% CI = 0.53 to 0.96), but not among women with BMIs of less than 25 kg/m2 (HR = 1.62, 95% CI = 0.97 to 2.71, Pinteraction = .01). Conclusions: A low-fat dietary intervention was associated with reduced pancreatic cancer incidence in women who were overweight or obese in the WHI-DM trial. Caution needs to be taken in interpreting the findings based on subgroup analyses.

Tandem walking as a quick screening test for vestibular disorders.

OBJECTIVES/HYPOTHESIS: Although many screening tests of balance are available, few of them have been well validated for clinical or research uses. The goal of this study was to test an updated version of an old test, Tandem Walking, to determine how useful it is for screening patients with vestibular disorders. STUDY DESIGN: Case-control study. METHODS: Subjects were 90 adult patients with vestibular disorders and 292 healthy adult controls. They were tested on the number of correct tandem steps they could perform with arms crossed and eyes closed in a series of 10 steps. Correct steps could be nonconsecutive. Subjects were given one practice trial with eyes open and three experimental trials with eyes closed. RESULTS: Receiver operating characteristic (ROC), and sensitivity and specificity were calculated. ROC values, sensitivity, and specificity were, at best, only moderate, no matter how the age range was cut. Even for subjects in the age group with the highest ROC value (i.e., age less than 50 years), ROC = 0.8, sensitivity = 0.77, and specificity = 0.72. CONCLUSIONS: These results indicate that 23% of patients will not be identified. Therefore, we recommend that if this test is used for screening patients in the clinic or healthy volunteers, the result should be interpreted with care. LEVEL OF EVIDENCE: 3b.
