RESUMO

STUDY DESIGN: Retrospective radiographic review. OBJECTIVE: The objectives of the study were to determine the contributions to lumbar lordosis (LL) through both the vertebrae and the intervertebral disc (IVD), and to investigate the relationships between lumbar sagittal spine measurements and age and gender. SUMMARY OF BACKGROUND DATA: A small body of literature exists on the relative contributions of vertebral body and IVD morphology to LL, the effects of L4-S1 on overall LL, and the relationships/correlations between lumbar sagittal spine measurements. METHODS: Patients who met the inclusion criteria were retrospectively evaluated. Measurements included LL, pelvic incidence (PI), and % contributions of vertebral body wedging/IVD wedging/L4-S1 to LL. Patients were separated into groups by age and sex, demographic data were collected, and statistical analysis was completed. RESULTS: LL decreased with age, although PI remained similar. Females demonstrated increased LL and vertebral body wedging % than males. Males demonstrated increased L4-S1% than females. Despite a decrease in LL with age, patients maintained L4-S1% and IVD wedging %. There was a significant negative relationship between PI and IVD wedging, PI and L4-S1%, and LL and L4-S1%. CONCLUSIONS: During aging, the lumbar spine loses LL linearly. This occurs in the IVD and vertebral bodies. Females have increased LL compared with males, because of an increase in vertebral body wedging and IVD/vertebral wedging cranial to L4. In patients with high PI or LL, increased LL occurs from cranial to L4 and from vertebral body wedging.

RESUMO

Perinatal mental health is recognized as a priority component of obstetrical care. Perinatal patients often turn to their obstetrician for help with mental health concerns as they view them as their primary health care provider. Unfortunately, obstetricians face challenges in providing adequate support due to time constraints and limited expertise. Integrated behavioral health care offers a collaborative and cost-effective solution to enhance patient care and clinician satisfaction. Integrated behavioral health clinicians possess fundamental skills to care for patients throughout the reproductive lifespan and assist obstetricians in identifying and managing common mood concerns.

RESUMO

Objectives: Adolescents who are pregnant and identify as Black are exposed to more societal harms that increase their and their offspring's risk for poor health outcomes. The Colorado Adolescent Maternity Program (CAMP) offers comprehensive, multidisciplinary (medical, behavioral health, nutrition, case management), trauma-informed obstetric care to pregnant adolescents to ensure the healthiest pregnancy and birth possible and pursue health equity. The present study aimed to examine ethnic and racial disparities in preterm birth and low birth weight before and after implementation of a trauma-informed model of care. Methods: Participants were 847 pregnant adolescents (ages 12-22 years; 41% self-identified as Hispanic, 32% as non-Hispanic Black, 21% as non-Hispanic white) who received prenatal treatment-as-usual (TAU) or trauma-informed treatment. Demographic information, mental health symptoms, and birth outcomes were abstracted from medical records. Results: Overall, findings provided support that implementation of a trauma-informed model of prenatal care led to equitable birth outcomes across racial and ethnic groups. Specifically, Black adolescents in the TAU group were more than twice as likely to deliver preterm or low birth weight infants compared with white and Hispanic adolescents. In the trauma-informed group, however, there were no statistical differences in birth outcomes across racial/ethnic groups, indicating an elimination of disparities in both preterm birth and low birth weight in this population. These more equitable birth outcomes occurred even in the context of adolescents of color having reported more severe depression symptoms postimplementation. Conclusions: These findings provide evidence that a health system-level intervention, herein trauma-informed obstetric care for adolescents, can play a meaningful role in the reduction of racial disparities in birth outcomes.

RESUMO

BACKGROUND: Adolescents with developmental disabilities and their caregivers often seek menstrual management. Caregivers frequently serve as medical decision-makers, and little is known about caregiver goals for menstrual management and satisfaction over time. OBJECTIVE: Assess caregiver reasons for initiating menstrual management in adolescents with disabilities and satisfaction over 12 months. METHODS: Prospective cohort study of caregivers of adolescents with developmental disabilities seeking menstrual management at a pediatric and adolescent gynecology clinic. Data derive from caregiver surveys and adolescents' electronic medical records. RESULTS: Ninety-two caregiver-adolescent pairs enrolled. The mean age of adolescents was 14.4 (±2.6). The most common method started was levonorgestrel intrauterine device (LNG-IUD; 52, 56.5%), followed by oral norethindrone acetate (21, 22.8%). Caregivers cited hygiene concerns (84.8%), behavioral problems (52.2%), and heavy/excessive bleeding (48.9%) as reasons for initiating menstrual suppression. Caregivers who identified hygiene or heavy/excessive bleeding as the most important reason for management were more likely to select LNG-IUD (p = 0.009). Caregivers who cited behavioral/mood or seizure concerns as the most important reason were more likely to choose other methods (p < 0.05). At 12 months, caregiver satisfaction with all methods was high (66.2-86.9 on a 100-point scale). For every additional day of bleeding, satisfaction decreased by 3.7 points (95% CI: 2.3-5.0). CONCLUSIONS: Caregiver satisfaction with all methods is high; however, it negatively correlates with days of bleeding. Caregiver reasons for menstrual suppression influence the method chosen. Management may reflect both patient and caregiver priorities; research is needed to better understand shared decision-making models that promote reproductive autonomy in adolescents with a developmental disability.

RESUMO

BACKGROUND: Nonsexually acquired genital ulcers have been described among girls who are prepubertal after various viral illnesses due to mucosal inflammation from an immunologic response. Until recently, nonsexually acquired genital ulcers have only been associated with viral infections. CASE: We present a case of an adolescent girl developing nonsexually acquired genital ulcers after both her first and second coronavirus disease 2019 (COVID-19) vaccine doses. Her course followed an expected timeline for severity and resolution of ulcers. CONCLUSIONS: Aphthous ulcers may arise from inflammatory effects of COVID-19 vaccination. Clinical monitoring after COVID-19 vaccination from all formulations should include assessment for nonsexually acquired genital ulcers if vaginal pain is reported.

RESUMO

Integrated perinatal behavioral healthcare provides opportunities to support women and their babies as part of their primary care medical home. The COVID-19 pandemic required significant changes to be made to medical practices to enhance safety and reduce risk, particularly for vulnerable populations, including pregnant women. Previously established modes of mental health service delivery in the HEART program, an integrated behavioral health program embedded in a primary care clinic for adolescent mothers and their babies, and the PROMISE Clinic, an integrated obstetric behavioral health program that serves pregnant women, quickly pivoted to telehealth services because of the pandemic. HEART serves a racially and ethnically diverse patient population, with over 85% of patients publicly insured. The PROMISE Clinic serves a socioeconomically, racially, and ethnically diverse patient population. Behavioral health clinicians implemented a variety of technology-based services including telephone interventions and support, virtual visits using iPads during medical visits, and video visits that patients accessed from their homes. In HEART, behavioral health visits continued at pre-COVID rates during telehealth adaptations. In the PROMISE clinic, the number of perinatal women seen doubled, the total number of patient contacts tripled, and the missed appointment rate significantly decreased during COVID. In the PROMISE clinic, significantly more White and Hispanic perinatal women were seen during COVID and telehealth adaptations, while significantly fewer Black perinatal women were seen during this period. Further research is indicated to examine patient attitudes towards telehealth services, barriers to treatment for Black women, and outcome data.


El cuidado integrado de salud perinatal y del comportamiento ofrece oportunidades para apoyar a las mujeres y sus bebés como parte central del cuidado médico primario. La pandemia del COVID-19 requirió cambios significativos en las prácticas médicas para mejorar la seguridad y reducir el riesgo, particularmente para grupos de población vulnerables, incluyendo las mujeres embarazadas. Las maneras de ofrecer el servicio de salud mental previamente establecidas en la Clínica para Madres Jóvenes (YMC), una clínica de cuidado primario para madres adolescentes y sus bebés, y la Clínica PROMESA, un equipo integrado de salud obstétrica y del comportamiento, rápidamente cambiaron a los servicios de tele-salud a causa de la pandemia. El personal clínico de salud del comportamiento implementó una variedad de servicios con base en la tecnología, incluyendo intervenciones por teléfono, visitas virtuales llevadas a cabo durante visitas médicas, así como visitas grabadas en video a las que las pacientes tenían acceso desde sus casas. En YMC, las visitas de salud del comportamiento continuaron a los niveles de pre-COVID durante las adaptaciones a la tele-salud. En la Clínica PROMESA, significativamente más mujeres blancas e hispanas perinatales fueron vistas durante las adaptaciones de tele-salud, mientras que significativamente menos mujeres negras perinatales fueron vistas durante este período. Se indica una mayor investigación para examinar las actitudes de las pacientes hacia los servicios de tele-salud, las barreras al tratamiento de mujeres negras y los datos de resultados.


Les soins de santé périnatale intégrés offrent des occasions de soutenir les femmes et leurs bébés dans le contexte de leurs services de soin médical à domicile. La pandémie COVID-19 a exigé des changements importants pour les pratiques médicales afin de renforcer la sécurité et de réduire les risques, particulièrement pour les populations vulnérables, y compris les femmes enceintes. Des modes déjà établis de service de santé mentale dans la Clinique des Jeunes Femmes (Young Mothers Clinic, soit YMC), une clinique de soins primaires pour les mères adolescentes et leurs bébés et la Clinique PROMISE, une équipe de santé obstétrique comportementale intégrée ont vite pivoté vers des services de télésanté à cause de la pandémie. Les cliniciens de santé du comportement ont mis en place une variété de services basés sur la technologie y compris des interventions par téléphone, des visites virtuelles faites durant des visites médicales et des visites par vidéo que les parents ont regardé depuis chez eux. Pour ce qui concerne la YMC les visites de santé comportementale ont continué à des taux pré-COVID durant les adaptations de télésanté. Pour ce qui concerne la clinique PROMISE le nombre de femmes périnatales vues a doublé, le nombre total de contacts aux patientes a triplé, et le taux de rendez-vous manqués a considérablement baissé durant le COVID. A la clinique PROMISE bien plus de femmes périnatales blanches et hispaniques ont été vues durant les adaptions de télésanté, alors que bien moins de femmes périnatales noirs ont été vues durant cette période. Nous indiquons des directions de recherches supplémentaires pour examiner les attitudes de la patiente envers les services de télésanté, les barrières au traitement des femmes noires et les données des résultats.

RESUMO

During pregnancy, physical activity relates to better maternal and child mental and physical health. Accelerometry is thought to be effective for assessing free-living physical activity, but the feasibility/acceptability of accelerometer use in pregnant adolescents has not been reported. In this short communication, we conducted secondary analysis of a small pilot study to describe the feasibility/acceptability of accelerometry in pregnant adolescents and the preliminary results of physical activity characteristics. Participants were recruited from a multidisciplinary adolescent perinatal clinic. Physical activity was assessed with wrist-worn accelerometers. Feasibility was described as median days of valid wear (≥10 h of wear/day) for the total sample and the number/percentage of participants with ≥4 days of valid wear. Sensitivity analyses of wear time were performed. Acceptability ratings were collected by structured interview. Thirty-six pregnant (14.6 ± 2.1 gestational weeks) adolescents (17.9 ± 1.0 years) participated. Median days of valid wear were 4 days. Seventeen participants (51.5%) had ≥4 days of valid wear. There were no differences in characteristics of adolescents with vs. without ≥4 days of valid wear. Twenty participants (60.6%) had ≥3 days of valid wear, 24 (72.7%) ≥2 valid days, and 27 (81.8%) ≥1 valid wear day. Acceptability ratings were neutral. Assessing physical activity with accelerometry in pregnant adolescents was neither feasible nor acceptable with the current conditions. Future research should investigate additional incentives and the potential utility of a lower wear-time criterion in pregnant adolescents.

RESUMO

INTRODUCTION: The importance of developing military strategies to decrease preventable death by mitigating hemorrhage and reducing time between the point of injury and surgical intervention on the battlefield is highlighted in previous studies. Successful implementation of Tactical Combat Casualty Care (TCCC) throughout elements of the USA and allied militaries begins to address this need. However, TCCC implementation is neither even nor complete in the larger, conventional force. Army Aviators are at risk for preventable death as they do not receive prehospital care training and are challenged to render prehospital care in the austere environment of helicopter operations. Army aviators are at risk for preventable death due to the challenges to render prehospital care in the austere environment of helicopter operations. Helicopters often fly at low altitudes, engage in direct action in support of ground troops, operate at a great distance from medical facilities, typically do not have medical personnel onboard, and can have long wait times for medical evacuation services due to the far forward nature of helicopter operations. MATERIALS AND METHODS: This is a quality improvement pre-post-intervention design study evaluating the implementation of a combat casualty care training program for Army aviators using well-established evidence-based guidelines for providing care to casualties on the battlefield. The evaluation consisted of participants' self-perceived confidence in providing care to a casualty and change in knowledge level in combat casualty care in a pre/post-intervention design. Clinical skills of tourniquet application, nasopharyngeal airway placement, and needle chest decompression were assessed on a pass/fail grading standard. RESULTS: A total of 18 participants completed the pre- and post-education surveys. A paired t-test showed a statistically significant increase in total composite scores from pre (M = 24.67, SD = 5.06) to post-education self-efficacy (M = 37.94, SD = 2.10), t (17) = -11.29, p < 0.001. A paired t-test revealed a significant increase in exam scores from pre (M = 70.22, SD = 9.43) to post (M = 87.78, SD = 7.19), t (17) = -7.31, p < 0.001. There was no pre-intervention skills assessment, however, all participants (n = 18, 100%) passed the tourniquet application, needle chest compression, and insertion of nasopharyngeal airway. CONCLUSION: TCCC for Army Aviators is easily implemented, demonstrates an increase in knowledge and confidence in providing prehospital care, and provides effective scenario-based training of necessary psychomotor skills needed to reduce preventable death on the battlefield. TCCC for Army Aviators effectively takes the TCCC for All Combatants curriculum and modifies it to address the unique considerations in treating wounded aviators and passengers, both in flight and after crashes. This project demonstrates on a small scale how TCCC can be tailored to specific military jobs in order to successfully meet the intent of the upcoming All Service Member TCCC course mandated in DoD 1322.24. Beyond Army aviation, this program is easily modifiable for aviators throughout the military and civilian sector.

RESUMO

BACKGROUND: Excess gestational weight gain (GWG) in pregnant adolescents is a major public health concern. Excess GWG increases risk of pregnancy complications as well as postpartum and offspring obesity and cardiometabolic disease. Prevention interventions for pregnant adults that target lifestyle modification (i.e., healthy eating/physical activity) show insufficient effectiveness. Pregnant adolescents have distinct social-emotional needs, which may contribute to excess GWG. From an interpersonal theoretical framework, conflict and low social support increase negative emotions, which in turn promote excess GWG through mechanisms such as overeating and physical inactivity. METHODS: The current manuscript describes the design of a pilot randomized controlled feasibility trial of adolescent interpersonal psychotherapy (IPT) to address social-emotional needs and prevent excess GWG. Up to 50 pregnant, healthy adolescents 13-19y, 12-18 weeks gestation are recruited from an interdisciplinary adolescent maternity hospital clinic and randomized to IPT + usual care or usual care alone. IPT involves 6 individual 60-minute sessions delivered by a trained behavioral health clinician during 12-30 weeks gestation. Sessions include relationship psychoeducation, emotion identification and expression, and teaching/role-playing communication skills. Between sessions, adolescents are instructed to complete a daily journal and to have conversations to work on relationship goals. Outcomes are assessed at baseline, mid-program, post-program, and 3-months postpartum. Primary outcomes are feasibility and acceptability based upon rate of recruitment, session attendance, program acceptability ratings, and follow-up retention. Secondary outcomes are perinatal social functioning, stress, depression, and eating behaviors assessed with validated surveys and interviews; perinatal physical activity and sleep measured via accelerometer; GWG from measured weights; and at 3-months postpartum only, maternal adiposity by dual energy x-ray absorptiometry, maternal insulin sensitivity derived from 2-hour oral glucose tolerance testing, and infant adiposity by air displacement plethysmography. DISCUSSION: This pilot trial will address a key gap in extant understanding of excess GWG prevention for a high-risk population of adolescents. If feasible and acceptable, brief psychotherapy to address social-emotional needs should be tested for its effectiveness to address excess GWG and postpartum maternal/infant health. If effective, such an approach has potential to interrupt an adverse, intergenerational cycle of social-emotional distress, obesity, and cardiometabolic disease among young mothers and their offspring. TRIAL REGISTRATION: ClinicalTrials.gov NCT03086161, retrospectively registered.

RESUMO

PROBLEM: Sociodemographic identities, including race, culture, ethnicity, gender, and sexual orientation (race and culture), are recognized as important determinants of health, with significant impacts on patients' health outcomes, but teaching medical students about this is challenging. The authors sought to identify areas for improvement in delivery of critical content about race, culture, structural inequalities, and health disparities within a set of virtual patient cases used by U.S. medical schools and develop revision guidelines. APPROACH: A workgroup (medical students and faculty) conducted a literature review in 2017 to identify challenges and best practices for teaching and learning about race and culture in medicine. Using an analytic framework informed by this review, they analyzed 63 Aquifer virtual patient teaching cases for effectiveness of the presentation of race and culture, resulting in six main themes describing common mistakes or pitfalls. They then developed an evidence-based guide for systematic case revision. OUTCOMES: The authors present a novel, practical guide for medical educators to use to revise existing teaching cases and improve the delivery of critical concepts surrounding race and culture. This guide includes fundamental definitions and six sections to guide structured case revision based on the main themes. It includes examples of language, suggested edits, and the rationale and evidence for recommendations. NEXT STEPS: Feedback from faculty and students regarding implementation of the guide and delivery of revised content in Aquifer cases will be critical in determining the guide's effectiveness. This structured guide may be adapted to a variety of teaching modalities in medicine.

RESUMO

Adolescent mothers experience higher rates of trauma and abuse, as well as increased risks for mental health disorders, compared to adolescent girls who are not mothers, making them a particularly vulnerable population and contributing to them feeling less supported by or allied with their medical provider. Women with a history of childhood abuse face increased rates of obstetric complications; their infants are at increased risk for low birthweight, developmental and intellectual delays, and behavioral problems. Trauma-informed care has become widespread in mental health settings; however, this model has not been as commonly applied to other settings, such as patient-centered medical homes (PCMHs). The Colorado Adolescent Maternity Program (CAMP) is an obstetric and pediatric medical home for pregnant and parenting adolescent girls through age 22 and their children located within Children's Hospital Colorado. With the integration of behavioral health into CAMP, and given the prevalence of trauma histories among adolescent mothers reported in the literature, programmatic and operational changes to clinical care were made using the Substance Abuse and Mental Health Services Administration's six key principles of a trauma-informed approach. Data showed that nearly 30% of participants reported a history of trauma. Following the inclusion of trauma-informed principles, patients had significantly higher rates of attendance at prenatal appointments (p < .001) and significantly lower rates of low birthweight babies (p = .02). Future programmatic changes and long-term assessment outcomes of this trauma-informed approach in a PCMH are also discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMO

BACKGROUND: The past decade has witnessed an upsurge in medical curriculum partnerships established across national boundaries to offer students at the foreign institution (host) a learning experience comparable to that of students at the exporting institution (home). However, since the learning environments and national healthcare contexts differ greatly between institutions, concerns have been raised in the literature about potential low quality of curriculum delivery, inadequate preparation of students to practice in the host country healthcare setting, and a culture shock for host students having to study a home curriculum.. The experiences and opinions of medical students related to these concerns have not been investigated. This study takes an explorative approach on key challenges faced by host institution students. METHOD: Three hundred sixty-one host students recruited from 3 partnerships completed a survey about their motives, transition from high school, language, preparedness for practice, future career planning, and general satisfaction. Descriptive statistics of closed-ended items and thematic analysis of open-ended items were performed. RESULTS: Findings revealed that students generally held positive views of the education they received. Switching to a new language of instruction (English) and learning environment was not perceived as a major obstacle. However, a significant portion of students who as non-nationals did not speak the language of the patient population felt this complicated effective workplace-based learning. CONCLUSION: Despite differences in learning experiences, host students felt the partnership afforded opportunities to acquire unique academic competencies and boost their career. Further adaptation of the home curriculum to the host country healthcare system may be beneficial, without losing sight of medical curriculum partnerships' potential to offer graduates an international outlook on global healthcare.

RESUMO

Background: Breast cancer patients who do not respond to neoadjuvant therapy have a poor prognosis. There is a pressing need for novel targets and models for preclinical testing. Here we report characterization of breast cancer patient-derived xenografts (PDX) largely generated from residual tumors following neoadjuvant chemotherapy.Experimental Design: PDXs were derived from surgical samples of primary or locally recurrent tumors. Normal and tumor DNA sequencing, RNASeq, and reverse phase protein arrays (RPPA) were performed. Phenotypic profiling was performed by determining efficacy of a panel of standard and investigational agents.Results: Twenty-six PDXs were developed from 25 patients. Twenty-two were generated from residual disease following neoadjuvant chemotherapy, and 24 were from triple-negative breast cancer (TNBC). These PDXs harbored a heterogeneous set of genomic alterations and represented all TNBC molecular subtypes. On RPPA, PDXs varied in extent of PI3K and MAPK activation. PDXs also varied in their sensitivity to chemotherapeutic agents. PI3K, mTOR, and MEK inhibitors repressed growth but did not cause tumor regression. The PARP inhibitor talazoparib caused dramatic regression in five of 12 PDXs. Notably, four of five talazoparib-sensitive models did not harbor germline BRCA1/2 mutations, but several had somatic alterations in homologous repair pathways, including ATM deletion and BRCA2 alterations.Conclusions: PDXs capture the molecular and phenotypic heterogeneity of TNBC. Here we show that PARP inhibition can have activity beyond germline BRCA1/2 altered tumors, causing regression in a variety of molecular subtypes. These models represent an opportunity for the discovery of rational combinations with targeted therapies and predictive biomarkers. Clin Cancer Res; 23(21); 6468-77. ©2017 AACR.

RESUMO

STUDY OBJECTIVE: A rare cause of adolescent abdominal pain includes isolated tubal torsion (ITT). Presentation is nonspecific and few studies have investigated ITT in adolescents. Our study objective was to describe the presentation and management of ITT in a large case series. DESIGN: Retrospective observational case series. SETTING: Tertiary care children's hospital. PARTICIPANTS: Participants were female and aged 3-21 years, presenting to Children's Hospital Colorado and diagnosed with ITT between January 2004 and August 2015. INTERVENTIONS AND MAIN OUTCOME MEASURES: Clinical presentation, physical exam, laboratory findings, surgical diagnosis, and treatment provided. RESULTS: A total of 19 cases were included. Average age was 13.3 (range, 11-18) years. In patients with unilateral abdominal pain (n = 16), there was 100% correlation with side of adnexal pathology. Ultrasound examination in 14 of 18 cases (78%) noted abnormal findings ipsilateral to the ITT. Most cases were managed with laparoscopy (84%; n = 16 of 19) and detorsion with or without cystectomy (74%; n = 14 of 19). Salpingectomy was more common with prolonged pain greater than 24 hours (relative risk 5.6, 95% confidence interval, 0.7-39.0). The most common intraoperative finding was a paratubal cyst (74%; n = 14 of 19). When Doppler flow was performed, it was present in 88% (n = 16 of 18) of the affected adnexa. ITT was more common on the left side (68%; n = 13 of 19). CONCLUSION: The high occurrence of paratubal cysts might suggest pathologic predisposition for ITT. Providers should maintain a high index of suspicion for ITT, particularly if associated with a paratubal cyst. Classic examination findings of surgical abdomen, leukocytosis, fever, and absence of Doppler flow are infrequently present. Laparoscopy and detorsion are appropriate treatments for managing ITT.

RESUMO

STUDY OBJECTIVE: The purpose of this study was to assess whether variability exists in the management of acute abnormal uterine bleeding (AUB) in adolescents between pediatric Emergency Department (ED) physicians, pediatric gynecologists, and adolescent medicine specialists. DESIGN: Retrospective chart review. SETTING: Tertiary care medical center ED. PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We included girls aged 9-22 years who presented from July 2008 to June 2014 with the complaint of acute AUB. Patients were identified using the International Classification of Diseases, ninth revision codes for heavy menstrual bleeding, AUB, and irregular menses. Exclusion criteria included pregnancy and current use of hormonal therapy. One hundred fifty patients were included. RESULTS: Among those evaluated, 61% (n = 92) were prescribed hormonal medication to stop their bleeding by providers from the ED, Adolescent Medicine, or Pediatric Gynecology. ED physicians prescribed mostly single-dose and multidose taper combined oral contraceptive pills (85%; n = 24), compared with Adolescent Medicine (54%, n = 7), and Gynecology (28%, n = 13). Pediatric gynecologists were more likely than ED physicians to treat patients with norethindrone acetate, either alone or in combination with a single dose combined oral contraceptive pill (61%, n = 33 vs 7%, n = 2; P < .001). CONCLUSION: Variations in treatment strategies for adolescents who present with acute AUB exist among pediatric specialties, which reflects a lack of standardized care for adolescents. Prospective evaluation of the shortest interval to cessation of bleeding, side effects, and patient satisfaction are valuable next steps.

RESUMO

BACKGROUND: Vaginal agenesis is rare and generally presents with primary amenorrhea and cyclic abdominal pain. We describe a case in which the diagnosis was delayed due to lack of initial pelvic examination and atypical findings on imaging. CASE: A 13-year-old girl with a known renal anomaly presented to the emergency department with primary amenorrhea and cyclic abdominal pain. She declined a pelvic examination and had normal laboratory testing and pelvic magnetic resonance imaging results. At 16 months later, she presented again and was diagnosed with vaginal agenesis and a large endometrioma. SUMMARY AND CONCLUSION: This case illustrates the importance of the physical examination in the evaluation of primary amenorrhea. Further, it demonstrates that hematometra may not be present on imaging. Here, an endometrioma was the only abnormality noted on magnetic resonance imaging after 18 months of retrograde menstruation.

RESUMO

BACKGROUND AND OBJECTIVES: Many schools rely upon community preceptors for office-based education of medical students. These preceptors struggle to balance clinical care with the learning needs of students. We aim to gain a deeper understanding of the teaching rewards and challenges of current community preceptors. METHODS: Five schools' family medicine clerkship directors conducted in-depth interviews of two exemplary preceptors at each of their programs. Following qualitative analysis of the interviews, three directors conducted one focus group at their school. The individual and group interviews were recorded, transcribed, and analyzed using grounded theory. RESULTS: Exemplary community preceptors described strategies to improve the learning environment and specific teaching approaches. Well-known teaching strategies such as role modeling, adjusting instruction to the learner's needs, and selecting patients appropriate for a specific student were used. They also described newer techniques such as co-learning and integrating technology, for example, accessing online, current practice guidelines together with the student. They detailed challenges to teaching, including time constraints and too much content to cover and provided advice about teaching tools. CONCLUSIONS: While challenged by clinical demands, preceptors enjoyed teaching and found it rewarding. They used time-proven teaching strategies as well as technology and online resources to facilitate ambulatory teaching. Community preceptors continue to struggle to integrate learners and the priorities of the medical school curriculum into the clinical environment. Further development of electronic tools and other resources to support the teaching needs of preceptors may contribute to learning and help minimize preceptor burden.

RESUMO

OBJECTIVE: Physicians often overlook important contextual clues that patients give during an encounter. The objective of our study was to increase medical students' knowledge and skills in identifying contextual issues. METHODS: Six consecutive learning experiences, including a standardized patient (SP) encounter and activities designed to trigger reflection, were implemented within a first-year Introduction to Clinical Medicine course. Evaluation of the intervention was measured through self-confidence, attitudes, SP history checklist, and student and small group facilitator evaluations. RESULTS: Standardized patient encounters, coupled with activities designed to trigger reflection, can help students identify patients' contextual clues. Students' confidence in eliciting patient clues significantly increased after the intervention. Our results suggest that some contextual clues were more difficult for students to elicit. CONCLUSION: Multi-faceted approaches that include activities to trigger reflection are effective in teaching students to recognize and respond to contextual clues, however, more research is needed. PRACTICE IMPLICATIONS: While students elicited most clues in this study, they struggled with identifying some clues. These results suggest the need for additional research and educational development in this area.

RESUMO

CONTEXT: Dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) decrease with aging and are important androgen and estrogen precursors in older adults. Declines in DHEAS with aging may contribute to physiological changes that are sex hormone dependent. OBJECTIVE: The aim was to determine whether DHEA replacement increases bone mineral density (BMD) and fat-free mass. DESIGN, SETTING, AND PARTICIPANTS: A randomized, double-blinded, controlled trial was conducted at an academic research institution. Participants were 70 women and 70 men, aged 60-88 yr, with low serum DHEAS levels. INTERVENTION: The intervention was oral DHEA 50 mg/d or placebo for 12 months. MEASUREMENTS: BMD, fat mass, and fat-free mass were measured before and after intervention. RESULTS: Intent-to-treat analyses revealed trends for DHEA to increase BMD more than placebo at the total hip (1.0%, P = 0.05), trochanter (1.2%, P = 0.06), and shaft (1.2%, P = 0.05). In women only, DHEA increased lumbar spine BMD (2.2%, P = 0.04; sex-by-treatment interaction, P = 0.05). In secondary compliance analyses, BMD increases in hip regions were significant (1.2-1.6%; all P < 0.02) in the DHEA group. There were no significant effects of DHEA on fat or fat-free mass in intent-to-treat or compliance analyses. CONCLUSIONS: DHEA replacement therapy for 1 yr improved hip BMD in older adults and spine BMD in older women. Because there have been few randomized, controlled trials of the effects of DHEA therapy, these findings support the need for further investigations of the benefits and risks of DHEA replacement and the mechanisms for its actions.
