Sonographic imaging of hand and wrist injuries: applications in the ER setting.

Acute osseous and soft tissue injuries to the hand and wrist are a common cause for ER visitation. Though diagnostic assessment has historically remained the province of conventional radiography, CT and MRI, sonography is gaining increasing acceptance and utilization. Offering multiple inherent advantages as an imaging modality, ultrasonic assessment has proven its utility in the evaluation of ligamentous and tendinous carpal and digital injuries as well as infection and inflammation. In this review, we will initially discuss sonographic technique and relevant normal anatomical features. Illustrative examples of soft tissue and osseous injuries of the hand and wrist as well as complicated infections most likely to be encountered in the emergency setting will then be presented together with a discussion of their relevant clinical considerations and management.

Community Outbreak of HIV Infection Linked to Injection Drug Use of Oxymorphone--Indiana, 2015.

On January 23, 2015, the Indiana State Department of Health (ISDH) began an ongoing investigation of an outbreak of human immunodeficiency virus (HIV) infection, after Indiana disease intervention specialists reported 11 confirmed HIV cases traced to a rural county in southeastern Indiana. Historically, fewer than five cases of HIV infection have been reported annually in this county. The majority of cases were in residents of the same community and were linked to syringe-sharing partners injecting the prescription opioid oxymorphone (a powerful oral semi-synthetic opioid analgesic). As of April 21, ISDH had diagnosed HIV infection in 135 persons (129 with confirmed HIV infection and six with preliminarily positive results from rapid HIV testing that were pending confirmatory testing) in a community of 4,200 persons.

The influence of perceptions of HIV infection, care, and identity on care entry.

The benefits of accessing HIV care after diagnosis (e.g., improved clinical outcomes and reduced transmission) are well established. However, many persons who are aware that they are HIV infected have never received HIV medical care. During 2008-2010, we conducted 43 in-depth interviews in three health department jurisdictions among adults who had received an HIV diagnosis but who had never accessed HIV medical care. Respondents were selected from the HIV/AIDS Reporting System, a population-based surveillance system. We explored how respondents perceived HIV infection and HIV medical care. Most respondents associated HIV with death. Many respondents said that HIV medical care was not necessary until one is sick. Further, we explored how these perceptions may have conflicted with one's identity and thus served as barriers to timely care entry. Most respondents perceived themselves as healthy. All respondents acknowledged their HIV serostatus, but many did not self-identify as HIV-positive. Several respondents expressed that they were not ready to receive HIV care immediately but felt that they would eventually attempt to access care. Some stated that they needed time to accept their HIV diagnosis before entering care. To improve timely linkage to care, we suggest that during the posttest counseling session and subsequent linkage-to-care activities, counselors and service providers discuss patient perceptions of HIV, particularly to address beliefs that HIV infection is a "death sentence" or that HIV care is necessary only for those who exhibit symptoms.

Sonographic Diagnosis of Velamentous and Marginal Placental Cord Insertion.

Routine second trimester ultrasound (US) examinations include an assessment of the umbilical cord given its vital role as a vascular conduit between the maternal placenta and fetus during fetal development. Placental cord insertion abnormalities can be identified during prenatal US screening and are increasingly recognized as independent risk factors for various complications during pregnancy and delivery. The purpose of this pictorial review is to illustrate examples of velamentous and marginal placental cord insertion with an emphasis on how to differentiate their morphology using color Doppler US.

Medication-related barriers to entering HIV care.

Early entry to HIV care and receipt of antiretroviral therapy improve the health of the individual and decrease the risk of transmission in the community. To increase the limited information on prospective decisions to enter care and how these decisions relate to beliefs about HIV medications, we analyzed interview data from the Never in Care Project, a multisite project conducted in Indiana, New Jersey, New York City, Philadelphia, and Washington State. From March 2008 through August 2010, we completed structured interviews with 134 persons with no evidence of HIV care entry, 48 of whom also completed qualitative interviews. Many respondents believed that HIV care entails the passive receipt of medications that may be harmful or unnecessary, resulting in reluctance to enter care. Respondents voiced concerns about prescription practices and preserving future treatment options, mistrust of medications and medical care providers, and ambivalence about the life-preserving properties of medications in light of an assumed negative impact on quality of life. Our results support the provision of information on other benefits of care (beyond medications), elicitation of concerns about medications, and assessment of psychosocial barriers to entering care. These tasks should begin at the time a positive test result is delivered and continue throughout the linkage-to-care process; for persons unwilling to enter care immediately, support should be provided in nonmedical settings.

Using HIV surveillance data to monitor missed opportunities for linkage and engagement in HIV medical care.

Monitoring delayed entry to HIV medical care is needed because it signifies that opportunities to prevent HIV transmission and mitigate disease progression have been missed. A central question for population-level monitoring is whether to consider a person linked to care after receipt of one CD4 or VL test. Using HIV surveillance data, we explored two definitions for estimating the number of HIV-diagnosed persons not linked to HIV medical care. We used receipt of at least one CD4 or VL test (definition 1) and two or more CD4 or VL tests (definition 2) to define linkage to care within 12 months and within 42 months of HIV diagnosis. In five jurisdictions, persons diagnosed from 12/2006-12/2008 who had not died or moved away and who had zero, or less than two reported CD4 or VL tests by 7/31/2010 were considered not linked to care under definitions 1 and 2, respectively. Among 13,600 persons followed up for 19-42 months; 1,732 (13%) had no reported CD4 or VL tests; 2,332 persons (17%) had only one CD4 or VL test and 9,536 persons (70%) had two or more CD4 or VL tests. To summarize, after more than 19 months, 30% of persons diagnosed with HIV had less than two CD4 or VL tests; more than half of them were considered to have entered care if entering care is defined as having one CD4 or VL test. Defining linkage to care as a single CD4 or VL may overestimate entry into care, particularly for certain subgroups.

HIV counseling, testing and referral experiences of persons diagnosed with HIV who have never entered HIV medical care.

The HIV counseling, testing, and referral (CTR) encounter represents an important opportunity to actively facilitate entry into medical care for those who test positive for HIV, but its potential is not always realized. Ways to improve facilitation of linkage to care through the CTR encounter haven't been explored among HIV-infected persons who have not entered care. We conducted 42 structured and qualitative interviews among HIV-infected persons, diagnosed 5-19 months previously, in Indiana, Philadelphia and Washington State, who had not received HIV medical care. Respondents related individual and system-level barriers, as well as recommendations for improving the effectiveness of CTR as a facilitator of linkage to HIV medical care through more active referrals, and for strengthening the bridge between CTR and linkage to care services. Our findings suggest that standards for active case referral by CTR staff and integration of CTR and linkage to care services are needed.
