Persistence of a Gastrocutaneous Fistula after gastrostomy removal in children: Incidence and predictive factors

Background/Purpose: The aims of this study were to determine the incidence of persistent gastrocutaneous fistulas (GCF) after gastrostomy removal and to identify associated risk factors. Methods: This retrospective study included 75 children from the Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland who had a gastrostomy performed between 1988 and 2010. The records of the children were reviewed for sex, age at the time of gastrostomy removal, underlying disease, type of gastrostomy placement and length of use, and then analyzed in order to find a correlation between the GCF and these parameters. Results: The gastrostomy orifice did not close spontaneously within the first month in 33 of the patients (44%), and 15 subsequently underwent surgical closure. The mean duration of gastrostomy use was significantly longer in children who developed a persistent GCF (30 vs. 19 months, P = 0.03). The other parameters studied did not show any significant association with the persistence of a GCF. Conclusions: The only predictive factor determining the persistence of a GCF was found to be the timespan between the placement and removal of the gastrostomy appliance. Elective surgical closure of the gastrostomy orifice should be considered after 1 month of persistent GCF

Construction and classification of some Galois modules

In our previous paper we describe the Galois module structures of $p$th-power class groups $K^\times/{K^{\times p}}$, where $K/F$ is a cyclic extension of degree $p$ over a field $F$ containing a primitive $p$th root of unity. Our description relies upon arithmetic invariants associated with $K/F$. Here we construct field extensions $K/F$ with prescribed arithmetic invariants, thus completing our classification of Galois modules $K^{\times}/K^{\times p}$

Contribution of Dual Fluorescein and Indocyanine Green Angiography to the Appraisal of Presumed Tuberculous Chorioretinitis in a Non-endemic Area.

To assess the respective involvement of retina versus choroid in presumed ocular tuberculosis (POT) in a non-endemic area using dual fluorescein (FA) and indocyanine green angiography (ICGA). We retrospectively analyzed cases diagnosed with POT at the Centre for Ophthalmic Specialized Care, Lausanne, Switzerland. Angiography signs were quantified using an established dual FA and ICGA scoring system for uveitis. Out of 1739 uveitis patients visited from 1995 to 2014, 53 (3%) were diagnosed with POT; of whom 28 patients (54 eyes) had sufficient data available to be included in this study. Of 54 affected eyes, 39 showed predominant choroidal involvement, 14 showed predominant retinal involvement and one had equal retinal and choroidal scores. Mean angiographic score was 6.97 ± 5.08 for the retina versus 13.48 ± 7.06 for the choroid (P < 0.0001). For patients with sufficient angiographic follow-up after combined anti-tuberculous and inflammation suppressive therapy, mean FA and ICGA scores decreased from 6.97 ± 5.08 to 3.63 ± 3.14 (P = 0.004), and 13.48 ± 7.06 to 7.47 ± 5.58 (P < 0.0001), respectively. These results represent the first report of the respective contributions of retinal and choroidal involvement in POT. Choroidal involvement was more common, for which ICGA is the preferred examination. In cases of compatible uveitis with positive results of an interferon-gamma release assay, particularly in a region that is non-endemic for TB, dual FA and ICGA should be performed to help establish the diagnosis of ocular tuberculosis and improve follow-up

Some remarks on Hilbertian fields (An appendix to the paper “Galois averages” by R. Massy)

AbstractThe paper gives proofs of some results just claimed in [R. Massy, Galois averages, J. Number Theory 113 (2005) 244–275]. For instance, it is proved that for a finite non-trivial separable extension M/F, M≠F, of Hilbertian fields finitely generated over their prime field, the quotient group M×/F×, for the corresponding multiplicative groups of non-zero elements, cannot be a torsion group of finite exponent

Testing Reinecke’s chronology of the Early Bronze Age with radiocarbon dating: new evidence from Southern Bavaria

In this article we present a critical view of the current chronological framework for Early Bronze Age burials from Southern Bavaria, by using radiocarbon dating to re examine Paul Reinecke’s relative chronological classification system. We also examine chronological divisions established by other scholars based on his system. The results of our study show a complex pattern of local groups appropriating new types or styles of objects from others, which then influences the timeline for the appearance of such type objects. Our findings show that every region had its own socio cultural history with a slightly different chronologyIntroduction Results of radiocarbon dating - Regionality as a problem for wide range relative chronology - Grave goods and burial customs as a problem/change for relative chronology in the later eba Conclusio

Parallélogrammes Galoisiens

RésuméWe generalize the notion of a Galois extension by that of a Galois parallelogram; a Galois extension is just a flat Galois parallelogram. The existence of Galois parallelograms is proved in the number field case. We state numerous general properties of Galois parallelograms which give, in particular, the usual properties of classical Galois theory. Then, we introduce a “two-dimensional Galois theory” by generalizing to Galois parallelograms the classical Galois bijection for finite Galois extensions
