OBJECTIVEWe describe the long-term outcomes of 510 diabetic patients with critical limb ischemia (CLI) and an active foot ulcer or gangrene, seen at the University Hospital of Rome Tor Vergata, a tertiary care clinic.RESEARCH DESIGN AND METHODSThese patients were seen between November 2002 and November 2007 (mean follow-up 20 ± 13 months [range 1–66 months]). The Texas Wound Classification was used to grade these wounds that were either class C (ischemia) and D (ischemia+infection) and grade 2–3 (deep–very deep). This comprehensive treatment protocol includes rapid and extensive initial debridement, aggressive use of peripheral percutaneous angioplasty, empirical intravenous antibiotic therapy, and strict follow-up.RESULTSThe protocol was totally applied (with percutaneous angioplasty [PA+]) in 456 (89.4%) patients and partially (without percutaneous angioplasty [PA−]) in 54 (10.6%) patients. Outcomes for the whole group and PA+ and PA− patients are, respectively: healing, n = 310 (60.8%), n = 284 (62.3%), and n = 26 (48.1%); major amputation, n = 80 (15.7%), n = 67 (14.7%), and n = 13 (24.1%); death, n = 83 (16.25%), n = 68 (14.9%), and n = 15 (27.8%); and nonhealing, n = 37 (7.25%), n = 37 (8.1%), and n = 0 (0%) (χ2 <0.0009). Predicting variables at multivariate analysis were the following: for healing, ulcer dimension, infection, and ischemic heart disease; and for major amputation, ulcer dimension, number of minor amputations, and age. Additional predicting variables for PA+ patients were the following: for healing, transcutaneous oxygen tension [ΔTcPo2]; and for major amputation, basal TcPo2, basal A1C, ΔTcPo2, and percutaneous angioplasty technical failure.CONCLUSIONSEarly diagnosis of CLI, aggressive treatment of infection, and extensive use of percutaneous angioplasty in ischemic affected ulcers offers improved outcome for many previously at-risk limbs. Ulcer size >5 cm2 indicates a reduced chance of healing and increased risk of major amputation. It was thought that all ulcers warrant aggressive treatment including percutaneous angioplasty and that treatment should be considered even for small ischemic ulcers.

Our results indicate that CCSVI has no role in either MS risk or MS severity.

Morton's neuroma (MN) is a frequent cause of metatarsalgia. The aim of our study was to evaluate the efficacy of neuroma alcoholsclerosing therapy (NAST) under US guide in MN after a 10-month follow-up. Forty intermetatarsal neuromas underwent alcohol-sclerosing therapy after sonographic evaluation of their dimensions and echotexture. After subcutaneous anesthesia, a sclerosing solution composed of anesthetic (carbocaine-adrenaline 70%) and ethylic alcohol (30%) was injected inside the mass under US guidance. The procedure was repeated at intervals of 15 days until the resolution of the symptoms. A total or partial symptomatic relief was obtained in 36 cases (90%). No procedure-related complications were observed. Transitory plantar pain, due to the flogistic reaction induced by the sclerosing solution, occurred in 6 cases (15%). The 10-month follow-up revealed a 20-30% mass volume reduction and an adiposus-like change in echotexture. In the 4 cases (10%) of therapeutic failure, the preliminary sonography demonstrated a hypoechoic echotexture with a strong US beam attenuation corresponding to a highly fibrous neuroma after surgical resection. The NAST is a feasible and cost-efficient procedure with high rates of therapeutic success.

To evaluate the efficacy of transcatheter foam sclerotherapy (TCFS) in pelvic varicocele using sodium-tetradecyl-sulfate foam (STSF), we conducted a retrospective study in 38 patients (mean age, 36.9 years; range, 22-44 years) with pelvic congestion syndrome (PCS) treated between January 2000 and June 2005 by TCFS. Pelvic pain was associated with dyspareunia in 23 (60.5%) patients, urinary urgency in 9 (23.7%) patients, and worsening of pain during menstruation and at the end of a day of work in 7 (18.4%) and 38 (100%) patients, respectively. Diagnosis was made by pelvic and transvaginal color Doppler ultrasound examination, demonstrating ovarian or pelvic varices with a diameter >5 mm presenting venous reflux. TCFS was performed in all patients, using 3% STSF. Follow-up was performed by physical examination, pelvic and transvaginal Doppler ultrasound examination and by a questionnaire-based assessment of pain at 1, 3, 6, and 12 months after the procedure. Technical success was achieved in all patients (100%). In three patients a pelvic colic-like pain occurred immediately after sclerotic agent injection, disappearing spontaneously after a few minutes. No recurrent varicoceles were observed during a 12-month follow-up. A statistically significant improvement in each category of specific symptoms was observed at 1, 3, 6, and 12 months after the procedure. We conclude that TCFS of female varicocele using a 3% STSF is safe and effective for the treatment of PCS. It is associated with a significant reduction of symptoms and can be regarded as a valid alternative to other endovascular and surgical techniques.

SummaryExtracorporeal photopheresis (ECP) has been considered an efficient dendritic cell (DC) therapy, used for treating both T cell malignancy, as well as T cell-mediated diseases. During the ECP procedure leucocytes are exposed to photoactivable agent 8-methoxypsolaren (8-MOP) and ultraviolet (UV) A radiation (PUVA) prior to reinfusion. Despite its clinical efficacy the mechanism of action remains elusive. As it has been reported that ECP might promote the differentiation of monocytes into immature DCs, we investigated the effects of UVA light (2 J/cm 2 ) and 8-MOP (100 ng/ml) on in vitro monocyte-to-DC differentiation from normal donors. DCs were generated from human purified CD14 + cells. Because monocytes are killed by PUVA and taking into account that only 5-10% of circulating mononuclear cells are exposed to PUVA during the ECP procedure, we developed an assay in which 10% of PUVA-treated monocytes were co-cultured with untreated monocytes. We first demonstrate that the presence of 10% apoptotic cells and monocyte activation were not enough to induce monocyte differentiation into DCs. Adding cytokines to our culture system, we obtained immature DCs characterized by significantly higher phagocytic activity and human leucocyte antigen D-related (HLA-DR) expression. These DCs preserved the capacity to be activated by lipopolysaccharide, but showed a reduced capacity to induce allogeneic T cell proliferation when first co-cultured with 10% of PUVAtreated cells. Our experimental design provides a novel insight into the real action of 8-MOP and UVA light on dendritic cell biology, suggesting an additional mechanism by which 8-MOP and UVA light exposure may influence immune responses.
