The ATHENA study expanded on the safety and efficacy data derived from first-line trials of bevacizumab combined with standard chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC). In ATHENA, 2,264 patients received first-line bevacizumabcontaining therapy in routine oncology practice. Overall survival (OS) data are now mature; additional analyses from this large data set can provide insights into treatment duration and the effect of prolonged bevacizumab exposure, where data are currently limited. Patients with HER2- negative LR/mBC received first-line bevacizumab with standard chemotherapy until disease progression, unacceptable toxicity, or physician/patient decision. We performed subgroup analyses on data from patients treated for ≥12 months and those who continued single-agent bevacizumab after stopping chemotherapy. After median follow-up of 20.1 months, median OS was 25.2 months (95% confidence interval [CI] 24.0-26.3 months) in the entire population. Median OS was 30.0 months (95% CI 28.5-32.7 months) in 1,205 patients who continued bevacizumab after discontinuation of chemotherapy and 18.4 months (95% CI 17.2-19.7 months) in 1,058 patients who discontinued bevacizumab before or at the same time as stopping chemotherapy. Bevacizumab treatment was continued for ≥12 months in 473 patients (21%). In most, bevacizumab was administered as monotherapy for extended periods after stopping chemotherapy. In the subgroup of patients treated for ≥12 months, the median time to onset of grade 3-5 adverse events was 5.0 months. There was no evidence that first onset of adverse events of special interest, except for proteinuria, was more common in later than earlier cycles. No relationship was detected between development of hypertension and OS. Findings from these analyses suggest that patients with LR/mBC can receive bevacizumab for prolonged periods without major toxicity or progression of disease. In the absence of progression, continuation of single-agent bevacizumab appears to be a reasonable approach, with minimal toxicity and the possibility of long-term disease control. © Springer Science+Business Media, LLC. 2011.

Background The circadian pattern of blood pressure (BP) has yet to be defined among individuals with orthostatic hypotension (OH). The objective of this study was to evaluate whether OH is associated with nocturnal change in systolic BP. Methods In a prospective study, we evaluated patients who were referred for 24-h ambulatory blood pressure monitoring (ABPM). All subjects underwent orthostatic BP testing before recording their respective 24-h ABPM. Results The study includes 185 subjects, 114 males, mean age 58 ± 18 years (range 19-89). Participants were classified, based on pattern of systolic BP changes at night, as dippers (greater than 10% decrease; n = 74), nondippers (0-10% decrease; n = 77), and reverse-dippers (increase; n = 34). Nineteen patients (10.3%) had OH. Almost all participants with OH (95%) had an abnormal diurnal BP pattern, and most of them (58%) were reverse-dippers, whereas only 56% of the participants without OH had an abnormal diurnal BP variation, and only 14% were reverse-dippers (P< 0.001). Systolic BP decreased with upright posture by 12 and 2mmHg in the reverse-dippers and the nondippers, respectively, and increased by 2mmHg in the dippers (P< 0.001). Postural changes in systolic BP were inversely related to the changes between day and night BP readings(r =-0.43; P< 0.01). In a multivariate linear regression analysis, orthostatic BP change, use of ≥2 antihypertensive drugs and female sex were related to nocturnal BP changes. Conclusions The decrease in BP during upright posture may be a marker of nondipping or reverse-dipping pattern of diurnal BP. © 2012 American Journal of Hypertension, Ltd.

Fractures of proximal femur are common among elderly people. They are associated with considerable morbidity and mortality. Identification of etiopathogenetic factors associated with fractures might facilitate prevention. Osteoporosis is commonly present in the heads of femurs. The prevalence of osteoarthritic changes in hip joints is controversial. Some authorities report low prevalence and even speculate on the protective effect of osteoarthritis against fractures. The goal of the study was to examine the association between osteoarthritic changes (radiologic and histologic) and fractures of the neck of the femur. The patient population included 41 patients undergoing replacement of femoral head for subcapital fracture; their ages ranged from 61 - 93 years of age. Radiologic criteria for osteoarthritis included: (a)narrowing of joint space (b) subchondral sclerosis (c) deformation of head of femur (d) subchondra cysts and (e] osteophytes. Osteoarthritic changes, usually mild, were present in 22 (54%) patients, regardless of age and gender The frequency of radioLogical changes was similar to the general population. HistoLogic findings included subchondral fibrosis and subchondral cysts. Mild subchondral fibrosis was present in 78% of cases. The findings support lack of association between osteoarthritic changes in hip joint and fracture of proximal femur, without a protective effect.

Fetal autopsies are effective in identifying the cause and/or mechanisms leading to death in cases of intrauterine fetal death. Autopsies for fetal anomalies are different. To summarize our experience with 569 autopsies of fetal anomalies which were performed during an 18-year period. Methods: A retrospective analysis of 569 autopsies of fetal anomalies was conducted, out of a total of 1067 fetal autopsies. The pregnancy weeks were 14 - 41. Among 569 cases, 88% were termination of pregnancies, 10% intrauterine death and 2% perinatal deaths. The diagnosis of a syndrome or disease process was made when a constellation of gross and/or histologic findings was met. Specific diagnoses were offered in cases of cystic diseases of kidneys, types of dwarfism, tumors and fetal hydrops. Teratogenic (acquired) processes, such as congenital infections, thrombosis and cerebral hemorrhages, were differentiated from malformations. In cases of multiple congenital anomalies, documentation of the entire spectrum of malformations facilitated the genetic counseling. First and foremost, the autopsy is performed in the interest of the parents, with their written consent and in accordance with limitations and requests which they pose. Autopsy results provide feedback to the prenatal imaging. They assist in focusing the genetic counseling. Autopsy reports provide tools of control for the health authorities. Autopsies for fetal anomalies are time consuming. They require skill and experience. They are helpfuL when the prenatal diagnosis raises differential diagnosis. They are Less helpful when the diagnosis is clear, i.e. chromosomal trisomy.

Purpose: This multicenter case series evaluates retrospectively the clinical outcomes of malpositioned implants surgically relocated in a more convenient position by segmental osteotomies. Materials and Methods: Authors who published, on indexed journals or books, works about malpositioned implant correction by segmental osteotomies were contacted. Five centers, out of 11 selected, accepted to participate in this study. The dental records of patients who underwent implant relocation procedures were reviewed. Implant survival rates were analyzed and a blinded assessor examined clinical photos and periapical radiographs to evaluate esthetic outcome (pink esthetic score [PES]) and changes of marginal bone level over time. Patients were requested to fill a verbal rating scale form about discomfort, compliance, and satisfaction related to the procedure. Results: Fifteen malpositioned implants relocated by segmental osteotomies were followed for a period ranging from 1 to 15 years (mean 6.0±3.9 years). The overall implant survival rate from baseline to the last follow-up visit was 100%. The mean marginal bone loss was 0.36mm at the 12-month follow-up visit and no relevant further changes were observed at the following examinations. Significant esthetic improvement was recorded at 1-year examination with PES evaluation (p<.0001). Patients' feedback described this procedure as not excessively invasive and uncomfortable, reporting a high final satisfaction rate. Conclusions: The present study suggests that implant relocation with segmental osteotomies could be an effective alternative method to correct the position of unrestorable malpositioned implants in a single-stage surgery. © 2012 Wiley Periodicals, Inc.
