We have observed the exceptional SMC star HD 5980 during several runs from 1989 to 1995 at ESO La Silla. CASPEC at the 3.6m telescope and EMMI in echelle and long slit modes at NTT were used for spectroscopy. Sub-arcsecond images were obtained using SUSI at NTT and also an adaptive optics system at the 3.6m telescope. In all our spectra taken before 1994 September HD 5980 shows a spectral type of WN6. The 1994 September spectra were taken shortly after the maximum of the visual light-curve of the LBV-like phenomenon (Bateson & Jones, 1993PVSS...19...50B) and about one month before the observations of Barba et al. (1995ApJ...446L..23B). Near maximum visual brightness, HD 5980 displays a WN11-like spectrum with the HeI lines and the Balmer lines Hdelta and Hgamma showing well-developed PCyg profiles. The sub-arcsecond images (0.17" FWHM), through the near infrared bands J, H, and K, obtained in 1993 and 1996, show no stellar components down to 6.7 mag fainter than HD 5980 in K at a separation of 1.0" and the 3sigma level. For a separation of 0.3" this upper bound is 4.1mag fainter than HD 5980. The observed behavior of this object raises serious problems for our comprehension of the LBV phenomenon in the conventional scenarios of massive star evolution. The present observations cover a crucial period in the evolution of HD 5980 and will therefore be helpful for better understanding this peculiar object especially during its outburst as well as the evolution of W-R stars in general.

Focal xanthogranulomatous pyelonephritis is an unusual form of chronic renal infection that is difficult to diagnose prior to surgery. We report on a 19-year-old woman who presented with a renal mass that mimicked malignancy. The diagnosis of focal xanthogranulomatous pyelonephritis was first suspected by radiological findings and further confirmed by histopathologic examination of percutaneous biopsy specimens of the lesion. Successful treatment of the patient was achieved with antibiotic therapy alone. Maximal efforts, including percutaneous renal biopsy, should be made to establish the diagnosis of focal xanthogranulomatous pyelonephritis before a therapeutic decision is reached. We recommend the use of antibiotics as a first-line treatment for patients with focal xanthogranulomatous pyelonephritis. [less ▲]

Infantile pyknocytosis (IP) is a rare hematological entity of newborns. It is a form of hemolytic anemia with unusual red cell morphology: the red blood cells are distorted, irregular, and small with many projections. Spontaneous resolution usually occurs by 4-6months of age. OBSERVATION: We describe the clinical features and biological parameters of 5 cases of IP. The first symptoms were always early jaundice, which required phototherapy. Anemia was severe in all babies and red blood cell transfusion was needed. CONCLUSION: IP is a rare cause of neonatal anemia whose diagnosis is based on a careful peripheral blood smear examination. In our study, anemia was severe and required red blood cell transfusion. Ethnic specificity and familial occurrence are reported in our experience. [less ▲]

Pylephlebitis, or septic thrombophlebitis of the portal vein, is an infrequent but life-threatening complication of abdominal septic events. The authors report the occurrence of pylephlebitis and multiple liver abscesses induced by a neglected intra-gastric migration of an adjustable silicone gastric band. The patient was successfully treated by broad-spectrum antibiotics and total gastrectomy with Roux-en-Y esophagojejunostomy. Postoperative recovery was marked by acute liver failure that was managed conservatively. The patient is alive and well at 1-year follow-up. This case emphasizes the interest in early removal of the band when intra-gastric migration is diagnosed. [less ▲]

Although intensive works have been devoted to spatiotemporal modeling during the last two decades, there are only a few models dedicated to relationships between two (or more) moving objects. This paper proposes a classification framework of spatiotemporal relationship models based on the ways spatiotemporal histories are analyzed. First, we discuss model conditions of application. Then we propose a classification of spatiotemporal relationship models based on a pyramidal representation of the quantity of extracted information, i.e. the nature and the complexity of provided information, from spatiotemporal histories. This classification aims helping users to choose adequate models for their purposes. The proposed spatiotemporal histories analysis method could lead to the development of new spatiotemporal relationship models. [less ▲]

A series of iron(II) chloride complexes of pentadentate ligands related to α,α,α’,α’-tetra(pyrazolyl)-2,6-lutidine, pz4lut, has been prepared to evaluate whether pyrazolyl substitution has any systematic impact on the electronic properties of the complexes. For this purpose, the new tetrakis(3,4,5-trimethylpyrazolyl)lutidine ligand, pz**4lut, was prepared via a CoCl2-catalyzed rearrangement reaction. The equimolar combination of ligand and FeCl2 in methanol gives the appropriate 1:1 complexes [FeCl(pzR4lut)]Cl that are each isolated in the solid state as a hygroscopic solvate. In solution, the iron(II) complexes have been fully characterized by several spectroscopic methods and cyclic voltammetry. In the solid state, the complexes have been characterized by X-ray diffraction, magnetic measurements and, in some cases, by Mössbauer spectroscopy. The Mössbauer studies show that the complexes remain high spin to 4 K and exclude spin-state changes as the cause of the surprising solid-state thermochromic properties of the complexes. Counterintuitive results of spectroscopic and structural studies showed that methyl substitution at the 3- and 5- positions of the pyrazolyl rings reduces the ligand field strength through steric effects whereas methyl substitution at the 4-position of the pyrazolyl rings increases the ligand field strength through inductive effects.
