A Vinyl Chloride-exposed Worker with an Adrenal Gland Angiosarcoma: A Case Report

Adrenal epithelioidangiosarcoma (AEA) is a rare neoplasm that accounts for less than 1% of sarcomas. Due to its rarity, it can easily be misdiagnosed, both by the clinician and the pathologist. Data on the patient’s occupational history was collected and analyzed. The bibliographic data was found on the PUBMED bibliographic search site after entering the word “extrahepaticangiosarcoma”. We report a case of adrenal epithelioidangiosarcoma (AEA) in a 68 yr-old Caucasian male factory worker exposed to Vinyl Chloride (VC) for 15 yr. He underwent surgery, chemotherapy and radiotherapy. Hepatic angiosarcoma is a known consequence of VC exposure, but occupational causality of extra-hepatic angiosarcoma is controversial. Extra-hepatic angiosarcomas have been reported in VC workers, but never AEA. Cancerogenic effects of VC involve all endothelial areas of the body and extra-hepatic endothelial tumors may also be caused by this substance. This is the first published report of AEA diagnosed in a worker exposed to VC.     

The Potential Role of Intragastric Balloon in the Treatment of Obese-Related Infertility: Personal Experience

The prevalence of people who are overweight or obese has increased dramatically in high-income countries over the past 20 years. There is a strong association between obesity and infertility, and weight loss can result in increased fecundity in obese women. The aim of this study is to demonstrate the potential role of intragastric balloon in the treatment of obese-related infertility. This is a retrospective study. A chart review of 27 obese women seen between September 2003 and July 2008 was performed. They all presented with the diagnosis of infertility and had undergone endoscopic intragastric balloon positioning. Among these women who tried unsuccessfully to become pregnant before weight loss, 15 became pregnant afterward. The pregnancies proceeded without complications and ended with live births. An improvement in the fertility status after weight loss has been described, although data on fertility after weight loss following bariatric surgery are still limited. The results obtained in our experience are not different from data reported in literature for bariatric surgery. Therefore, balloon treatment might be effective in young infertile obese women who wish to become pregnant.     

Bcl-6 gene mutations in primary cutaneous B-cell lymphomas

We analyzed mutations in the 5' non-coding region of the BCL-6 gene in 46 cases of primary cutaneous B-cell lymphomas (PCBCL), using a polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) method. The results indicate that PCBCL display a low frequency of mutations and support a marginal zone B-cell origin for most of these neoplasms.

Effectiveness of recommendations to prevent reactivation of latent tuberculosis infection in patients treated with tumor necrosis factor antagonists

OBJECTIVE: To investigate the impact of official recommendations regarding the management of latent tuberculosis (TB) infection on the rate of active TB in patients receiving treatment with tumor necrosis factor (TNF) antagonists. METHODS: Data on active TB rates and on screening and treatment of latent TB infection were extracted from the BIOBADASER (Spanish Society of Rheumatology Database on Biologic Products), a registry of patients with rheumatic conditions treated with TNF antagonists. The rates of active TB among the BIOBADASER patients were compared with those in the background Spanish population, and BIOBADASER patients with rheumatoid arthritis (RA) were compared with a cohort of RA patients from the EMECAR (Morbidity and Clinical Expression of Rheumatoid Arthritis) study who were not treated with TNF antagonists and were followed up for 5 years. RESULTS: Active TB developed in 34 patients, of whom 32 started taking TNF antagonists prior to the official recommendations on latent TB infection (pre-OR) and 2 began treatment after the recommendations were issued (post-OR). All cases of TB occurred during treatment with infliximab, and 28 of these patients had RA. Pre-OR, the active TB rate in BIOBADASER patients was 20.9-fold higher than in the background Spanish population, while RA patients in the BIOBADASER had rates 22.6- and 6.2-fold higher than the background and EMECAR populations, respectively. Post-OR, 324 patients with a tuberculin skin test result > or =5 mm and/or chest radiograph findings suggestive of past TB were treated for 9 months with isoniazid (INH). Post-OR, active TB rates among the BIOBADASER patients decreased by 78% (incidence risk ratio [IRR] 0.22, 95% confidence interval [95% CI] 0.03-0.88; P = 0.008), while among RA patients in the BIOBADASER, the rate dropped by 83% and reached the EMECAR rate (IRR 1.0, 95% CI 0.02-8.2). There were no INH treatment-related hospitalizations or deaths. CONCLUSION: Strategies to treat latent TB infection that are tailored to the at-risk population can effectively and safely lessen the likelihood of active TB in patients treated with TNF antagonists.
