Treatment of ovarian cancer with surgery, short-course chemotherapy and whole abdominal radiation

Background The primary aim was to induce a high number of pCR in early (FIGO IC, JIB + C)-and advanced (FIGO ffl—IV)—stage ovarian cancer with a surgery plus 4 cycles of cisplatin and meiphalan (PAMP) regimen. The second objective was to prevent relapse with WAR in patients in remission after chemotherapy. Patients and methods 218 eligible patients were treated after staging laparotomy with cisplatin 80 mg/sqm iv. on day 1 and melphalan 12 mg/sqm i.v. on day 2 q 4 weeks. Response was verified by second-look laparotomy. WAR was carried out with the open field technique on a linear accele rator (daily dose: 1.3 Gy, total dose: 29.9 Gy) in patients with pathological or clinicaJ CR or pathological PR with microscopical residual disease. Results 146/218 patients (67%, 95% CI: 61%-73%) responded to PAMIP: 56 (26%) achieved pCR, 24 (11%), cCR, 56 (26%) pPR and 10 (5%) cPR (c=clinical, p=pathological). Multivariate analyses revealed that in advanced stages (92 cases in remission), the achievement of pCR was the most important factor for longer time to failure (TIF) and survival. Only 5 1/118 (43%) patients in remission received WAR Early-stage patients <=55 years were more likely to have WAR than patients older than 55 years (77% vs. 23%; p= 0.02). Advanced-stage patients with cCR were less likely to be irradiated than patients with pCR or pPR (10% vs. 51%; p= 0.003). Toxicity of PAMP was acceptable with 10% of WHO grade 4 hematologic toxicity. Acute hematological toxicity of WAR caused interruption (3 3%) or incompleteness (3 3%) of irradiation in the majority of patients. Conclusions PAMP is an effective treatment for advanced ovarian cancer with a 67% response rate after 4 cycles. For the majority of patients in remission, WAR as a consolidation treatment was hardly feasible. For these patients new treatment modalities to consolidate remission are neede

Metastatic signet ring cell adenocarcinoma of bone marrow with bilateral ovarian masses: a case report

We present a case of metastatic signet ring cell adenocarcinoma of bone marrow with radiologically proven bilateral ovarian masses in a 50 year old Asian Indian female. Even after thorough search no extraovarian primary site could be found. Based on overall clinicopathologic correlation, a diagnosis of metastatic signet ring cell adenocarcinoma of bone marrow with uncertain primary was established

Migration drivers and migration choice: interrogating responses to migration and development interventions in West Africa

The notion of migration as being at least partly about ‘choice’ is deeply rooted in both academic thought and public policy. Recent contributions have considered migration choice as step-wise in nature, involving a separation between ‘aspiration’ and ‘ability’ to migrate, whilst stressing a range of non-economic factors that influence migration choices. But such nuances have not prevented the emergence of a significant area of public policy that seeks to influence choices to migrate from Africa through ‘irregular’ channels, or at all, through a range of development interventions. This paper explores evidence from West Africa on how young people formulate the boundaries of such choice. Drawing on approaches in anthropology and elsewhere that stress the value of a ‘future-orientated’ lens, we show how present uncertainty is a central framing that fundamentally limits the value of thinking about migration as a choice. This has important implications for policy on ‘migration and development’

European Association of Urology Guidelines Office Rapid Reaction Group: An Organisation-wide Collaborative Effort to Adapt the European Association of Urology Guidelines Recommendations to the Coronavirus Disease 2019 Era

The coronavirus disease 2019 (COVID-19) pandemic is unlike anything seen before by modern science-based medicine. As a scientific society, the European Association of Urology, via the guidelines, section offices, and the European Urology family of journals, we believe that it is important that we try to support urologists in this difficult situation. We aim to do this by providing tools that can facilitate decision making with the goal to minimise the impact and risks for both patients and health professionals delivering urological care, whenever possible, although it is clear that it is not always possible to mitigate them entirely. We hope that these revised recommendations will fill an important urological practice void and assist urologist surgeons across the globe as they do their very best to deal with the crisis of our generation

Certified reference materials for radionuclides in Bikini Atoll sediment (IAEA-410) and Pacific Ocean sediment (IAEA-412)

The preparation and characterization of certified reference materials (CRMs) for radionuclide content in sediments collected offshore of Bikini Atoll (IAEA-410) and in the open northwest Pacific Ocean (IAEA-412) are described and the results of the certification process are presented. The certified radionuclides include: 40K, 210Pb (210Po), 226Ra, 228Ra, 228Th, 232Th, 234U, 238U, 239Pu, 239+240Pu and 241Am for IAEA-410 and 40K, 137Cs, 210Pb (210Po), 226Ra, 228Ra, 228Th, 232Th, 235U, 238U, 239Pu, 240Pu and 239+240Pu for IAEA-412. The CRMs can be used for quality assurance and quality control purposes in the analysis of radionuclides in sediments, for development and validation of analytical methods and for staff training

Serum AMH concentration as a marker evaluating gonadal function in boys operated on for unilateral cryptorchidism between 1st and 4th year of life

The aim of this study was to measure the serum AMH (anti-Mullerian hormone) concentrations in a group of boys with or without cryptorchidism, evaluation of karyotypes, testicular position, morphology, and major length of the undescended testes. Fifty boys who were 1–4 years old (median = 2.4 years) with unilateral cryptorchidism were evaluated. All of them underwent orchidopexy in 2010. Prior to the procedure, all of the subjects had undergone karyotyping to exclude chromosomal abnormalities. Fifty healthy boys within the same age range (median = 2.1 years) admitted for planned inguinal hernia repair in 2010, served as controls. Blood samples were collected, while obtaining blood for standard laboratory tests routinely performed before the surgeries. Medians of AMH in boys with cryptorchidism were lower than in boys with inguinal hernia and differed significantly between two groups. Undescended testes were generally found in superficial inguinal pouch (n = 46), in two cases were noted to be in the external ring of the inguinal canal, and in another two instances, in the abdominal cavity. The major lengths of the undescended testes were smaller in comparison to the testes positioned normally (mean of 1 cm vs. a mean of 1.5 cm, respectively). In nine of the cases, the testes had turgor deficit, a drop shape, with epididymides that were small, dysplastic, and separated from the testis. The authors found that AMH was lower in boys with unilateral cryptorchidism (also found to have smaller testis) when compared with the control group

A compact and cost-effective hard X-ray free-electron laser driven by a high-brightness and low-energy electron beam

We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very stable, compact and cost-effective X-ray FEL facility driven by a low-energy and ultra-low-emittance electron beam travelling through short-period undulators. It delivers stable hard X-ray FEL radiation at 1-Å wavelength with pulse energies of more than 500 μJ, pulse durations of ~30 fs (root mean square) and spectral bandwidth below the per-mil level. Using special configurations, we have produced pulses shorter than 1 fs and, in a different set-up, broadband radiation with an unprecedented bandwidth of ~2%. The extremely small emittance demonstrated at SwissFEL paves the way for even more compact and affordable hard X-ray FELs, potentially boosting the number of facilities worldwide and thereby expanding the population of the scientific community that has access to X-ray FEL radiation
