Intramural ectopic pregnancy: An individual patient data systematic review.

Intramural pregnancies (IMP) are very rare and represent about 1% of ectopic pregnancies (EPs). Despite a few reported cases, there is limited awareness & knowledge among sonographers and physicians. Moreover, no established diagnostic or treatment protocol exists for such a condition.

Incarcerated gravid uterus: A rare but potentially devastating obstetric complication.

Incarceration of the gravid uterus is a rare obstetric complication characterized by entrapment of the gravid uterus between the sacral promontory and pubic symphysis. Clinical symptoms are highly variable and may include low back pain, urinary retention, and nausea. A presumptive diagnosis can often be established based on correlation of clinical history and physical examination.

Contrast-Enhanced Ultrasound Appearance of Hypervirulent Klebsiella pneumoniae Liver Abscesses.

There has been a paradigm shift with Klebsiella pneumoniae (KP) emerging as the most frequently isolated bacterium in pyogenic liver abscesses in immunocompetent patients. Colonization of this hypervirulent KP strain has led to community-acquired liver abscesses. Septic seeding to distant sites of the body has been recognized and is strongly associated with diabetes.

Clinical Importance and Natural History of Biliary Sludge in Outpatients.

Objectives: Gallbladder sludge is a common diagnosis on routine abdominal sonography, yet its clinical importance is uncertain, especially in outpatients. To determine its natural history and potential future complications in this setting, we reviewed the imaging and clinical histories of nonhospitalized patients with a diagnosis of sludge on sonography.

Methods: We conducted a retrospective search of our institutional radiology information system for all sonographic reports using the key words "biliary sludge without gallstones" over a 3-year period.

ACR Appropriateness Criteria® Acute Pelvic Pain in the Reproductive Age Group.

Acute pelvic pain in premenopausal women frequently poses a diagnostic dilemma. These patients may exhibit nonspecific signs and symptoms such as nausea, vomiting and leukocytosis. The cause of pelvic pain includes a myriad of diagnostic possibilities such as obstetric, gynecologic, urologic, gastrointestinal, and vascular etiologies.

The disruptive radiologist.

Radiologists interact with many individuals during daily practice, including patients, technologists, and other physicians. Some interactions may potentially negatively affect patient care and are termed "disruptive" behaviors. These actions are not uncommon and may begin during training, long before a radiologist enters clinical practice.

ACR appropriateness Criteria® infertility.

Appropriate imaging for women undergoing infertility workup depends upon the clinician's suspicion for potential causes of infertility. Transvaginal US is the preferred modality to assess the ovaries for features of polycystic ovary syndrome (PCOS), the leading cause of anovulatory infertility. For women who have a history or clinical suspicion of endometriosis, which affects at least one third of women with infertility, both MRI and pelvic US can provide valuable information.

Utility of compact ultrasound in a mass surgical selection program in Africa: experience of a sonologist at the MV Africa Mercy Hospital Ship's screening day.

Compact ultrasound (US) was introduced in an austere setting with no other available imaging for an annual mass surgical screening day. Compact US examinations were performed on 25 patients from more than 7000 potential patients, as deemed possibly useful by the screening surgeons. Of the 20 patients with recorded data, compact US was helpful in 14 of 20 as a decision-making tool, obviating computed tomography for preoperative planning.

ACR appropriateness Criteria® second and third trimester bleeding.

Vaginal bleeding occurring in the second or third trimesters of pregnancy can variably affect perinatal outcome, depending on whether it is minor (i.e. a single, mild episode) or major (heavy bleeding or multiple episodes.

ACR Appropriateness Criteria® growth disturbances - risk of intrauterine growth restriction.

Fetal growth disturbances include fetuses at risk for intrauterine growth restriction. These fetuses may have an estimated fetal weight at less than the 10% or demonstrate a plateau of fetal growth with an estimated fetal growth greater than the 10%. Uteroplacental insufficiency may play a major role in the etiology of intrauterine growth restriction.

ACR appropriateness Criteria® first trimester bleeding.

Vaginal bleeding is not uncommon in the first trimester of pregnancy. Ultrasound is the foremost modality for evaluating normal development of the gestational sac and embryo and for discriminating the causes of bleeding. While correlation with quantitative βHCG and clinical presentation is essential, sonographic criteria permit diagnosis of failed pregnancies, ectopic pregnancy, gestational trophoblastic disease and spontaneous abortion.

ACR Appropriateness Criteria® clinically suspected adnexal mass.

Adnexal masses are a common problem clinically and imaging-wise, and transvaginal US (TVUS) is the first-line imaging modality for assessing them in the vast majority of patients. The findings of US, however, should be correlated with the history and laboratory tests, as well as any patient symptoms. Simple cysts are uniformly benign, and most warrant no further interrogation or treatment.

Radiology on the Africa Mercy, the largest private floating hospital ship in the world.

Objective: The Africa Mercy, a rehabilitated Danish ferry, is the largest private hospital ship in the world, devoted to providing medical and surgical care to the residents of West Africa, one of the poorest regions on the globe.

Conclusion: There is a small radiology department on board, along with six operating rooms and a small ICU and inpatient wards, and the former is described in this report, as well as opportunities for humanitarian work by volunteer radiologists.

Image quality in real-time teleultrasound of infant hip exam over low-bandwidth internet links: a transatlantic feasibility study.

Evolution of communication systems, especially internet-based technologies, has probably affected Radiology more than any other medical specialty. Tremendous increase in internet bandwidth has enabled a true revolution in image transmission and easy remote viewing of the static images and real-time video stream. Previous reports of real-time telesonography, such as the ones developed for emergency situations and humanitarian work, rely on high compressions of images utilized by remote sonologist to guide and supervise the unexperienced examiner.

Compact ultrasound donations to medical facilities in low-resource countries: a survey-based assessment of the current status and trends.

Objectives: Many ultrasound (US) specialists, independently or as part of institutionally directed teams, have donated compact US equipment and training to rural and urban clinics in low-resource regions. The objective of our study was to assess the scope, impact, and characteristics of these donation and training activities.

Methods: We designed a 1-page, 10-question survey soliciting responses on donors, equipment, donation sites, training, and follow-up.

ACR Appropriateness Criteria® Multiple gestations.

Multiple gestations are high-risk compared with singleton pregnancies. Prematurity and intrauterine growth restrictions are the major sources of morbidity and mortality common to all twin gestations. Monochorionic twins are at a higher risk for twin-twin transfusion, fetal growth restriction, congenital anomalies, vasa previa, velamentous insertion of the umbilical cord and fetal death.

Donation and training of medical personnel in compact ultrasound in low-resource settings: how we do it.

The authors offer a concise summary of dos and don'ts for the radiologist/sonologist wishing to expand his horizons and join those physicians donating ultrasound equipment and training medical personnel in low-resource countries. Topics include choosing a site, obtaining ultrasound equipment, preparing to travel, and starting a training program. The most important points to keep in mind are: (1) be prepared for any circumstance; (2) do your homework ahead of time; (3) make sure there is a local group "on the ground" that can ensure the machine's sustainability; and (4) allow for much more time to get things accomplished than in the developed world.

Compact ultrasound for improving maternal and perinatal care in low-resource settings: review of the potential benefits, implementation challenges, and public health issues.

Objective: Ultrasound imaging, a front-line diagnostic tool for perinatal care, is rarely available in the developing world, where maternal and newborn mortality rates are starkly higher than elsewhere. The development of portable and inexpensive medical ultrasound machines (compact ultrasound) offers the possibility of broader use of ultrasound. Our objective was to assess the potential benefits and challenges of deploying compact ultrasound in developing countries for improving obstetric health.

Purpose: To evaluate the clinical and immunologic outcomes of DC (dendritic cell) vaccine with interleukin (IL)-2 and IFN-alpha 2a in metastatic renal cell carcinoma patients.

Experimental Design: Eighteen consented and eligible patients were treated. Peripheral blood monocytes were cultured ex vivo into mature DCs and loaded with autologous tumor lysate.

Transgender female youth and sex work: HIV risk and a comparison of life factors related to engagement in sex work.

This study examined the HIV risk behaviors and life experiences of 151 transgender female youth, ages 15-24, in Los Angeles and Chicago. Descriptive analyses and logistic regression modeling were used to identify life factors associated with ever having engaged in sex work. Sixty-seven percent of participants had ever engaged in sex work and 19% self-reported being HIV positive.

The chorionic bump in an ectopic pregnancy.

The chorionic bump, an irregular, convex bulge of the choriodecidual surface into the gestational sac (GS), is a recently described, uncommon abnormality of the 1st-trimester GS and is associated with a guarded prognosis for early pregnancy. The case of this 42-year-old female demonstrates a previously unreported relationship: a transvaginal sonographic finding of a chorionic bump associated with a spontaneous tubal ectopic pregnancy. This might support the hypothesis that the chorionic bump represents a small hematoma that bulges into the GS.

A tele-ultrasound system for real-time medical imaging in resource-limited settings.

Ultrasound has great potential as an imaging technology in resource-limited environments. We present a novel tele-ultrasound approach designed to realize that potential by connecting a remote technician to a radiologist. Our preliminary system, based on open-source software and commercial off-the-shelf hardware, uses custom software and a satellite Internet connection to create this link.
