Pregnant Woman Presenting with a Gross Retroperitoneal Mass: Surgical Treatment with Caval Replacement

A 40-year-old woman in the twenty-fifth week of pregnancy presented with a gross retroperitoneal mass. At the end of the pregnancy, the patient was submitted to surgery, and the gross infiltration of the inferior vena cava wall required the resection of the vena cava with its prosthetic substitution. The histopathological examination demonstrated the presence of a leiomyosarcoma of the inferior vena cava.

Potential experimental evidence of an Efimov state in

We describe the search of the Efimov state in 12C performed by analysing a large set of 3-α particles coincidence data measured at the LNS laboratories with the CHIMERA detector. The data are compatible with the presence of an Efimov state at the excitation energy of 7.485 MeV, with an excitation probability smaller than 0.3% of the population probability of the Hoyle state. The Efimov state gamma decay probability should be around 30%, much larger than the one of the Hoyle state. The population of this level is compatible with the Suda limit for the 3-α reaction rate in stars because its population should be possible only through direct 3-α reaction. More investigations improving the detector angular resolution are needed to confirm these preliminary observations

Entry techniques in laparoscopic radical and partial nephrectomy: A multicenter international survey of contemporary practices

BACKGROUND: There is no clear consensus as to the optimal method of entry in laparoscopic renal surgery and no reports have compared them in Urology. To analyze contemporary practice patterns in entry technique and port placement for laparoscopic kidney surgery. METHODS: We identified 60 high volume urological laparoscopic centers. A purpose-built questionnaire was sent to surgeons. The survey included 22 questions regarding access techniques and port configuration during laparoscopic kidney surgery. Data on were collected and retrospectively analyzed. Concordance among port configurations was assessed using Cohen's Kappa statistics. RESULTS: The survey was sent to 60 surgeons and completed by 32 of them. Surgical procedures included were laparoscopic radical nephrectomy (1177 LRN/year) and laparoscopic partial nephrectomy (1047 LPN/year). The transperitoneal route was preferred (85%). Hasson technique was used for the access in 55% of the cases. Patient lateral recumbent position is the most frequently used during the port placement (41%). Although there is a high variability in the port positioning among the surgeons, in more than 90% of cases it was found a specific concordance in triangulation of optics and operating trocars. There were no significant differences between port configuration in LRN and LPN. Limitations include retrospective design and limited sample. CONCLUSIONS: A standard port configuration has not been previously reported in urological literature. Our study suggests that the transperitoneal approach, the Hasson technique and a specific triangulation of optics and operating trocars have a significant concordance in some high volume laparoscopic urologic centers

The ASY-EOS Experiment at GSI

The elliptic-flow ratio of neutrons with respect to protons or light complex particles in reactions of heavy ions at pre-relativistic energies has been proposed as an observable sensitive to the strength of the symmetry term of the nuclear equation of state at supra-saturation densities. In the ASY-EOS experiment at the GSI laboratory, flows of neutrons and light charged particles were measured for 197Au+197Au collisions at 400 MeV/nucleon. Flow results obtained for the Au+Au system, in comparison with predictions of the UrQMD transport model, confirm the moderately soft to linear density dependence of the symmetry energy deduced from the earlier FOPI-LAND data
