Decreased collagen biosynthesis and increased collagenolysis may induce aneurysmal progress in arterial walls. Prolidase plays a role in collagen synthesis. In this study, we sought to evaluate whether there is a correlation between nonatherosclerotic coronary artery aneurysms (CAAs) and prolidase activity. A total of 174 CAAs were diagnosed in 144 (2.1%) patients among 6845 coronary angiographies performed between 2009 and 2012. In all, 23 (15.9%) patients had nonatherosclerotic aneurysms. Prolidase activity was compared to the results of 19 healthy volunteers with normal coronary arteries. Demographic parameters were similar between the groups. Mean prolidase activity was 241.6 ± 54.4 mU/mL in the coronary aneurysm group and 730.3 ± 243.1 mU/mL in the control group (P <.001). The incidence of CAAs ranges between 0.3% and 5.3% in the general population. Decreased prolidase activity may reduce collagen biosynthesis that may contribute to aneurysm formation.

Introduction: Lower limb ischemia may cause nonhealing ulcers, infection, amputation and even mortality in diabetic patients. In this study, we review our data of ischemic lower limb revascularization procedures in diabetic patients and present the early, mid- and long-term results. Material and methods: From March 2004 to September 2008, 83 patients with lower limb ischemia in Fontaine class III and IV underwent distal arterial bypass procedures. Saphenous vein grafts were used for below-knee arterial bypasses in all patients. In 16 (19%) patients femoropopliteal bypasses were performed with PTFE grafts. Short-term and long-term surgical results were evaluated. Results: Ulcer recovery was determined in 36% of patients. Graft patency was 95% and 1 death (1%) occurred in short-term follow-up. In long-term followup the total effectiveness rate was 74%. Graft patency was 79% and 6 deaths (7%) occurred during the follow-up. Conclusions: Lower limb ischemia is a serious event in patients with diabetes mellitus. The consequences may include increased mortality and morbidity in this particular patient population. However, distal arterial revascularizations are considerably effective procedures to avoid amputation, to eliminate symptoms, to promote ulcer recovery and to help the patient participate in social life with acceptable short, mid- and long-term follow-up results.

This pilot study analysed the outcome of open versus endoscopic curettage and bone grafting for the treatment of simple calcaneal bone cysts. A total of 26 patients were evaluated into two equal groups: group 1 was treated with traditional open curettage and bone grafting and group 2 was treated with endoscopic curettage and percutaneous bone grafting. Cyst size, operating time, length of stay, time to healing, complications, further surgery and radiological healing were recorded and differences were statistically compared. The mean age of the patients was 22.9 years (18 to 28) and the mean follow-up was 28.7 months (24 to 36). There were no statistically significant differences in regard to age of patients, cyst size and the follow-up periods in the two groups. The operating time and mean length of stay of group 2 patients was significantly shorter than group 1 patients (p < 0.001). The time to healing was similar in the two groups. The overall success rates for groups 1 and 2 were 92.3% (12 of 13) and 100% (13 of 13), respectively, and there were no statistically significant differences regarding radiological healing. This pilot study suggests that endoscopic curettage and percutaneous grafting is a simple and safe form of treatment, with similar results to those following open treatment. ©2011 British Editorial Society of Bone and Joint Surgery.

Neuroendocrine (NE) carcinoma of the breast is extremely rare and constitutes less than 0.1% of all breast tumors. Only a few studies are currently available in the litera-ture and a standard approach to treating this tumor has yet to be established. The aim of this study was to apply pathological treatment modalities in clinical practice and to select the most appropriate treatment accordingly. Six female patients were diagnosed with primary NE carcinoma of the breast. The patients underwent modified radical mastectomy with axillary dissection. Pathological specimens were stained with hematox-ylin and eosin and an immunohistochemical panel of antibodies [neuron-specific enolase (NSE), chromogranin, synoptophysin, estrogen and progesterone receptor, c-erbB2 and Ki-67]. The results showed that tumor size ranged from 2 to 4.5 cm in diam-eter. Lymph node metastasis was detected in 4 (67%) patients. Estrogen and progesterone receptor expression was found in 5 (83%) patients. None of the patients expressed c-erbB2. Chromogranin was found to be positive in 5 (83%) patients. Synoptophysin expression was detected in 5 (83%) patients. NSE was stained in 4 (67%) patients. An intraductal compo-nent was found in 5 (83%) patients. Lymphovascular invasion was found in 5 (83%) patients. Adjuvant chemotherapy was administered to patients with a Ki-67 index of ≥10%. Radiotherapy was administered to 4 (67%) patients, and 4 (67%) patients received hormonal therapy. The mean follow-up time was 31.1 months (range 12-52). All 6 patients survived, although following chemotherapy and tamoxifen, the disease progressed in 1 patient who received second-line hormonal therapy. In conclusion, NE carcinoma of the breast is a distinct entity. Management of this rare tumor may include surgery and radiotherapy depending on the size of the tumor and lymph node status. However, the exact role of chemotherapy and hormonal therapy has yet to be established.

Imatinib and second generation tyrosine kinase inhibitors has dramatically improved outcomes in patients with chronic myeloid leukemia but allogeneic hematopoietic stem cell transplantation remains an important treatment option in patients who failed imatinib and or second generation second generation tyrosine kinase inhibitors or progressed accelerated and blastic phase. This article provides recommendations regarding the selection of allogeneic hematopoietic stem cell transplantation for patients with chronic myeloid leukemia based on the evaluation of published articles and expert recommendations.
