Urethral hemangiomas are rare and benign tumors, probably originating from a unipotent angioblastic stem cell. They can vary in size and the clinical appearance can range from asymptomatic lesions to urethral bleeding or gross hematuria. We present the case of an 18-year-old male, with a history of urethral bleeding. Cystourethoscopy revealed a solitary bulging mass into the lumen, about 6 cm far from the external meatus. Doppler study confirmed that the lesion was in communication with the vessels of the left spongious body. The patient underwent surgical removal of the lesion. The post-procedure Doppler study revealed an inflammation-based remodeling of the spongoius urethra and the absence of the previous vascular connection. At the time of publication the patient is still symptom-free. The surgical removal of urethral hemangiomas is by far the technique of choice for treating such lesions in young patients, thus avoiding side effects of LASER treatments. Source

It has been proven that both resting and activated mast cells (MCs) and basophils are able to induce a significant increase in proliferation and survival of naïve and activated B cells, and their differentiation into antibody-producing cells. The immunological context in which this regulation occurs is of particular interest and the idea that these innate cells induce antibody class switching and production is increasingly gaining ground. This direct role of MCs and basophils in acquired immunity requires cell to cell contact as well as soluble factors and exosomes. Here, we review our current understanding of the interaction between B cells and MCs or basophils as well as the evidence supporting B lymphocyte-MC/basophil crosstalk in pathological settings. Furthermore, we underline the obscure aspects of this interaction that could serve as important starting points for future research in the field of MC and basophil biology in the peculiar context of the connection between innate and adaptive immunity. © 2014 Elsevier Ltd.

BACKGROUND: Microvascular decompression is an accepted, safe, and useful surgical technique for the treatment of trigeminal neuralgia. Autologous muscle or implant materials such as shredded Teflon are used to separate the vessel from the nerve but may occasionally be inadequate, become displaced or create adhesions and recurrent pain. OBJECTIVE: The authors evaluated the use of arachnoid membrane of the cerebellopontine angle to maintain the transposition of vessels from the trigeminal nerve. METHODS: The authors conducted a retrospective review of microvascular decompression operations in which the offending vessel was transposed and then retained by the arachnoid membrane of the cerebellopontine cistern, specifically by the lateral pontomesenchepalic membrane. RESULTS: This technique was used in 30 patients of the most recently operated series. Postoperatively, complete pain relief was achieved in 90% of the patients without any observed surgical complications. CONCLUSION: To the authors' knowledge this is the first report in which the arachnoid membrane is used in the microvascular decompression of the trigeminal nerve. While this technique can be used only for selected cases, the majority of the vascular compressions on the trigeminal nerve are due to the SCA, so this sling transposition technique can be useful and effective.

The impact of age as a poor prognostic factor in chronic myeloid leukemia (CML) has been well described. In the interferon era, elderly patients diagnosed as having chronic phase chronic myeloid leukemia (CP-CML) had shorter survival compared to younger patients. With the advent of target therapy with imatinib, several reports described improved responses in elderly late CP-CML patients treated with imatinib after IFN failure, with similar overall survival compared to younger population. Imatinib in newly diagnosed older patients showed similar rate of cytogenetic and molecular responses compared to younger patients. Few data are available relating elderly CML patients subset treated with second-generation TKIs after resistance/intolerance to imatinib: both nilotinib and dasatinib have demonstrated efficacy and limited toxicity profile as in younger patients. The aim of this review is, through the revision of published data, to highlight the fact that elderly CML patients can benefit from target therapy with limited adverse events. © 2012 Elsevier Ireland Ltd.

Objective: The performances of implantable cardioverter defibrillators and leads are important issues for healthcare providers and patients. In 2007 Sprint Fidelis leads were found to be associated with an increased failure rate and so the purpose of the study was to evaluate long-term mortality and clinical outcomes in patients implanted with Sprint Fidelis leads compared with Sprint Quattro leads. Design, setting, patients 508 patients with Sprint Fidelis leads and 468 with Sprint Quattro leads were prospectively followed in 12 Italian cardiology centres. Main outcome measures Information on hospitalisations and other clinical events were collected during scheduled and unscheduled hospital visits. Deaths were identified from medical records or via phone contacts with patients' family members or through the National Office of Vital Statistics. Results: Over a mean follow-up of 27±18 months 141 deaths occurred in the overall population. No death was observed in patients with diagnosed failing lead. Kaplan-Meier patient survival differed between the two lead groups (80±2% in Fidelis leads vs 70±4% in the Sprint Quattro leads at 4 years, p=0.002). Multivariate analyses showed that mortality was neither associated with lead type nor with diagnosed failed lead. The annual rate of lead failure was 1.8% patient-year for Fidelis leads and 0.2% for the Sprint Quattro leads. Conclusions: In our multicentre research, the clinical outcomes of patients with Fidelis leads differed from those of patients with Sprint Quattro leads. Nevertheless, neither mortality nor the combined endpoint of mortality and heart failure hospitalisations was associated with the lead type. Source
