A precarious pregnancy involving a patient with a large placental chorioangioma: a case report

Chorioangiomas are common placental neoplasms that are primarily asymptomatic, but the larger subtypes have a variable presentation and can result in severe pregnancy complications. We report a case of a pregnant patient who presented with a 10 x 12 x 10 cm placental chorioangioma at 32 weeks, despite an unremarkable ultrasound at 28 weeks. Since these more substantial chorioangiomas can induce fetal mortality, close surveillance with perinatology and neonatology consultation is necessary to enhance the probability of a favorable patient prognosis.     

Cancer coverage in a mainstream and Korean American online newspaper: lessons for community intervention

OBJECTIVE: Korean Americans have higher incidence of stomach, liver, and cervical cancer than most groups in CA, USA, and generally lower rates of cancer screening. To better target community interventions, we evaluated the cancer content in a leading Korean American newspaper, the Korea Daily, compared to a mainstream newspaper from the same metropolitan area, the Los Angeles (LA) Times. METHODS: Using the online versions of each newspaper for the year 2006, we counted articles mentioning cancer and evaluated the content in a random sample of 300 articles from each newspaper. Articles were categorized by relevance of cancer content and topic(s) covered. RESULTS: Although the LA Times had a higher proportion of articles mentioning cancer, the Korea Daily had more articles that primarily focused on cancer and addressed specific types of cancer. Articles in the Korea Daily were more likely to discuss prevention, while those in the LA Times more often focused on people, politics, or research. CONCLUSIONS: Smaller, ethnic newspapers may be more amenable to messages about prevention and appropriate places to target community-focused interventions. PRACTICE IMPLICATIONS: Health practitioners should consider submitting articles to ethnic newspapers and forming partnerships with journalists to cultivate this potential.     

Unusual stress fracture in an adolescent baseball pitcher affecting the trochlear groove of the olecranon

Stress fractures of the proximal ulna are known to occur in throwing athletes. Most cases extend to involve the olecranon, and cases limited to the trochlear groove are rare. In this report we present a 17-year-old elite baseball pitcher with a stress fracture of the trochlear groove of the proximal ulna. Diagnosis was made by demonstration of characteristic signal changes on MRI of the elbow. The fracture occurred at the cortical notch, also known as the pseudodefect of the trochlear groove. This case suggests that the cortical notch serves as an area of weakness predisposing pitchers to development of a stress fracture.     

Provision of HIV Counseling and Testing Services at Five Community-Based Organizations Among Young Men of Color Who Have Sex with Men

In the context of monitoring and improving CDC-funded HIV prevention programs, we describe HIV tests and infections, provision of results, previous HIV tests, and risk behaviors for young (aged 13–29) men of color who have sex with men who received HIV tests at five community-based organizations. Of 1,723 tests provided, 2.1% were positive and 75.7% of positives were previously unaware of their infection. The highest positivity rate was among men aged 25–29 (4.7%). Thirty-four percent of tests were provided to men who were tested for the first time. Over half the tests (53.2%) were provided to men who reported sex with a person of unknown HIV status, and 34% to men who reported sex with an anonymous partner. Continued and more focused prevention efforts are needed to reach and test young men of color who have sex with men and to identify previously undiagnosed HIV infections among this target population.     

Phantom experiments to improve parathyroid lesion detection

This investigation tested the hypothesis that visual analysis of iteratively reconstructed tomograms by ordered subset expectation maximization (OSEM) provides the highest accuracy for localizing parathyroid lesions using 99mTc-sestamibi SPECT data. From an Institutional Review Board approved retrospective review of 531 patients evaluated for parathyroid localization, image characteristics were determined for 85 99mTc-sestamibi SPECT studies originally read as equivocal (EQ). Seventy-two plexiglas phantoms using cylindrical simulated lesions were acquired for a clinically realistic range of counts (mean simulated lesion counts of 75 +/- 50 counts/pixel) and target-to-background (T:B) ratios (range = 2.0 to 8.0) to determine an optimal filter for OSEM. Two experienced nuclear physicians graded simulated lesions, blinded to whether chambers contained radioactivity or plain water, and two observers used the same scale to read all phantom and clinical SPECT studies, blinded to pathology findings and clinical information. For phantom data and all clinical data, T : B analyses were not statistically different for OSEM versus FB, but visual readings were significantly more accurate than T : B (88 +/- 6% versus 68 +/- 6%, p = 0.001) for OSEM processing, and OSEM was significantly more accurate than FB for visual readings (88 +/- 6% versus 58 +/- 6%, p < 0.0001). These data suggest that visual analysis of iteratively reconstructed MIBI tomograms should be incorporated into imaging protocols performed to localize parathyroid lesions.
