Abstract
Background: Diabetes mellitus-related lower extremity amputation is a major complication severely affecting patient survival and quality of life.
Objectives: To analyze epidemiological and clinical trends in the incidence and survival of lower extremity amputations among diabetes patients.
Methods: We conducted a retrospective observational cohort study of 565 consecutive diabetes patients who underwent their first non-traumatic lower extremity amputation between January 2002 and December 2009.
Results: Major amputations were performed in 316 (55.9%) patients: 142 above the knee (25.1%) and 174 below (30.8%); 249 (44.1%) had a minor amputation. The incidence rates of amputations decreased from 2.9 to 2.1 per 1000 diabetes patients. Kaplan-Meier survival analysis showed that first year mortality rates were lower among patients with minor amputations (31.7% vs. 39.6%, P = 0.569). First year mortality rates following below-knee amputation were somewhat lower than above-knee amputation (33.1 vs.45.1%, respectively). Cox regression model of survival at 1 year after the procedure found that age (HR 1.06 per year, 95% CI 1.04–1.07, P < 0.001), above-knee amputation (HR 1.36, 95% CI 1.01–1.83, P = 0.045) and ischemic heart disease (HR 1.68, 95% CI 1.26–2.24, P < 0.001) significantly increased one year mortality risk.
Conclusions: In this population-based study the incidence rate of non-traumatic amputations in diabetes patients between January 2002 and December 2009 decreased slightly. However, one year mortality rates after the surgery did not decline and remained high, stressing the need for a multidisciplinary effort to prevent amputations in diabetes patients.

Abstract
Background: Scleroderma lung disease (ILD-SSc) is treated mainly with cyclophosphamide (CYC). The effectiveness of CYC was judged after 12–24 months in most reports.
Objectives: To analyze the effect of monthly intravenous CYC on pulmonary function tests including forced vital capacity (FVC) and diffusing lung capacity (DLCO), as well as Rodnan skin score (mRSS), during long-term follow-up.
Methods: We retrospectively collected the data on 26 ILD-SSc patients who began CYC treatments before 2007. Changes in FVC, DLCO and mRSS before treatment, and at 1, 4 and 7 years after completion of at least six monthly intravenous CYC treatments for ILD-SSc were analyzed.
Results: Mean cumulative CYC dose was 8.91 ± 3.25 G. More than 30% reduction in FVC (0%, 8%, and 31% of patients), DLCO (15%, 23%, 31%), and mRSS (31%, 54%, 62%) at years 1, 4 and 7 was registered. During the years 0–4 and 4–7, annual changes in FVC, DLCO and mRSS were 3.2 vs. 0.42% (P < 0.040), 4.6 vs. 0.89% (P < 0.001), and 1.8 vs. 0.2 (P = 0.002). The greatest annual FVC and DLCO reduction over the first 4 years correlated with mortality (P = 0.022). There were no differences in the main variables regarding doses of CYC (< 6 G and > 6 G).
Conclusions: In patients with ILD-SSc, CYC stabilized the reduction of FVC during treatment, but this effect was not persistent. The vascular characteristic of ILD-SSc (DLCO) was not affected by CYC treatment. CYC rapidly improved the mRSS. This effect could be achieved with at least 6 G of CYC. Higher rates of annual reduction in FVC and DLCO in the first 4 years indicate the narrow window of opportunity and raise the question regarding ongoing immunosuppression following CYC infusions.

Abstract
Background: Renal hemangiomas are rare benign tumors seldom distinguished from malignant tumors preoperatively.
Objectives: To describe the Memorial Sloan-Kettering Cancer Center (MSKCC) experience with diagnosing and treating renal hemangiomas, and to explore possible clinical and radiologic features that can aid in diagnosing renal hemangiomas preoperatively.
Methods: Patients with renal hemangiomas treated at MSKCC were identified in our prospectively collected renal tumor database. Descriptive statistics were used to describe the patient characteristics and the tumor characteristics. All available preoperative imaging studies were reviewed to assess common findings and explore possible characteristics distinguishing benign hemangiomas from malignant renal tumors preoperatively.
Results: Of 6341 patients in our database 15 were identified. Eleven (73%) were males, median age at diagnosis was 53.3 years, and the affected side was evenly distributed. All but two patients were treated surgically. The mean decrease in estimated glomerular filtration rate (eGFR) after surgery was 36.3%; one patient had an abnormal presurgical eGFR and only two patients had a normal eGFR after surgery. We could not identify radiographic features that would make preoperative diagnosis certain, but we did identify features characteristic of hepatic hemangiomas that were also present in some of the renal hemangiomas.
Conclusions: Most renal hemangiomas cannot be distinguished from other common renal cortical tumors preoperatively. In select cases a renal biopsy can identify this benign lesion and the deleterious effects of extirpative surgery can be avoided.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem involvement due to immune dysregulation. Neuropsychiatric systemic lupus erythematosus (NPSLE) includes neurological syndromes involving the central, peripheral and autonomic nervous system, as well as psychiatric syndromes observed in patients with SLE in which other causes have been excluded. The pathogenesis of NPSLE has been attributed to many different mechanisms. In particular, autoantibody-mediated vasculopathy seems to play a major role in the pathogenesis of the clinical features. Several autoantibody specificities have been reported in the serum and cerebrospinal fluid of NPSLE patients. Recently, we demonstrated an association between serum anti-endothelial antibodies (AECA) and psychosis or depression in SLE patients, strengthening the notion of a possible role of this class of autoantibodies in the pathogenesis of the disease. The study of these autoantibodies could be a useful diagnostic and prognostic tool in patients with NPSLE.
