Mycotic pseudoaneurysm of the hepatic artery as a complication of radiofrequency ablation of hepatic metastases.

Image-guided radiofrequency ablation is frequently used to treat small hepatocellular carcinoma and metastases. Complications associated with this thermal-based technology for liver cancers arise via direct mechanical injury by the electrodes or collateral thermal damage to surrounding structures. This case report describes an unusual presentation of hepatic arterial mycotic pseudoaneurysm as melaena after percutaneous image-guided radiofrequency ablation for liver metastases in a patient with a previous surgical history of hepaticojejunostomy for cholangiocarcinoma. The patient had a lifesaving procedure to treat the hepatic pseudoaneurysm with transarterial glue embolization.

Understanding Why Older Adults With Type 2 Diabetes Join Diabetes Online Communities: Semantic Network Analyses.

BACKGROUND: As individuals age, chronic health difficulties may disrupt physical and social well-being. Individuals can turn to online communities to interact with similar peers, which may help buffer negative effects resulting from health difficulties. OBJECTIVE: This study investigated the reasons that older adults join a diabetes online community to better understand the specific resources that are being sought. METHODS: We used semantic network analyses to categorize the reasons participants provided for joining a community during the sign-up process. RESULTS: The most frequent reasons for joining were to seek information about their health condition, to help with self-management of health difficulties, for feelings of informational and social support, and for having a community with whom to share. Women were more likely to go online for sharing and companionship as well as for information and social support reasons, whereas men were more likely to go online for general information and self-management reasons. CONCLUSIONS: This study shows the reasons older adults seek to join a diabetes online community: for increased information and support regarding chronic health difficulties. Practitioners may want to consider ways to promote access to online communities among their older patients as a source of health information and a resource to provide a sense of community.

Stigma of HIV Testing on Online HIV Forums: Self-Stigma and the Unspoken.

Most studies examining HIV-related content in web forums have revolved around the most frequently used terms in HIV-related messages and topics, as well as the supportive nature of those messages. The current study explored barriers that prevent individuals from seeking HIV testing (specifically stigma). The current study analyzed a total of 210 threads and 319 posts, yielding 13 threads that revealed how individuals self-stigmatize and expressed how the fear of being diagnosed prevented them from seeking HIV testing. Results suggest that forums or online communities may perpetuate subculture values that deviate from mainstream values. Another important finding is that there is a lack of HIV testing information in forums for adolescents, which may contribute to the trend of young individuals engaging in risky sexual behaviors not getting tested in a timely fashion.

Static sac size with a type II endoleak post-endovascular abdominal aortic aneurysm repair: surveillance or embolization?

A best evidence topic was written according to a structured protocol. The question addressed was whether embolization is superior to surveillance for a type II endoleak associated with a static sac size post-endovascular abdominal aortic aneurysm repair (EVAR). Four hundred and sixty-one papers were identified, of which 10 papers presented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, and relevant outcomes and results are tabulated. A review of the available literature suggests that most type II endoleaks are innocuous and will seal spontaneously during the long-term follow-up, even when they persist for more than 6 months. An analysis of the large European Collaborators on Stent-Graft Techniques for Aortic Aneurysm Repair (EUROSTAR) registry that includes prospective data on 2463 patients from 87 European hospitals showed that type II endoleaks were not associated with an increased risk of rupture; this correlates well with the large single-centre studies included in this review. Based on the available evidence, we conclude that the management of most isolated type II endoleaks should be conservative-with close radiological follow-up--even when persistent, with intervention restricted to theoese associated with sac enlargement >5 mm over a 6-month period or >10 mm when compared with pre-EVAR diameter.

Treatment of a common iliac aneurysm by endovascular exclusion using the amplatzer vascular plug and femorofemoral crossover graft.

We report our initial experience using the Amplatzer Vascular Plug II (AVP2) in the treatment of a left common iliac aneurysm. Following investigation by computerized tomographic angiography and catheter angiography, a 79-year-old man was found to have a markedly tortuous iliac system, with a left common iliac artery aneurysm that measured 48 mm in maximal diameter. Due to the patient's age and comorbidities the surgical opinion was that conventional open repair was not suitable. However, due to the tortuous nature of the aneurysm and iliac vessels, standard endovascular repair, using either a bifurcated or an aorto-uni-iliac stent graft, was also not possible. A combined approach was used by embolizing the ipsilateral internal iliac artery using coils and excluding the aneurysm using two AVP2 occlusion devices, followed by femorofemoral crossover grafting. Total aneurysm occlusion was achieved using this method and this allowed the patient to have a much less invasive surgical procedure than with conventional open repair of common iliac aneurysms, thus avoiding potential comorbidity and mortality.
