Vaginal hysterectomy for uterovaginal prolapse: what is the incidence of concurrent gynecological malignancy?

Introduction And Hypothesis: Vaginal hysterectomy (VH) is a commonly performed procedure for the operative treatment of uterovaginal prolapse (UVP). The reported incidence of unexpected gynecological cancer in cases of VH for UVP ranges between 0.3 and 0.

Simple lifestyle recommendations and the outcomes of gestational diabetes. A 2 × 2 factorial randomized trial.

The benefits of exercise and behavioural recommendations in gestational diabetes mellitus (GDM) are controversial. In a randomized trial with a 2 × 2 factorial design, we examined the effect of exercise and behavioural recommendations on metabolic variables, and maternal/neonatal outcomes in 200 GDM patients. All women were given the same diet: group D received dietary recommendations only; group E was advised to briskly walk 20-min/day; group B received behavioural dietary recommendations; group BE was prescribed the same as B + E.

[Serious pulmonary embolism and thromboaspiration].

Pulmonary embolism is a common disease with a mortality rate of approximately 3%. Polytraumatised patients are particularly susceptible to thromboembolism because of prolonged immobilisation and inflammatory syndrome, thrombembolic risk also increases significantly during the peripartum period. Rapid diagnosis and intervention are essential for survival.

New syntheses and potential antimalarial activities of new 'retinoid-like chalcones'.

A series of 'retinoid-like chalcones' and diverse derivatives relative to licochalcone A were synthesized from a new enaminone synthon. These syntheses occurred via a new aromatic annelation. These new derivatives have been tested in vitro as potential antimalarial agents.

Syntheses, in vitro antibacterial and antifungal activities of a series of N-alkyl, 1,4-dithiines.

A series of dithiines were synthesized by cyclization of 4-(alkylamino)-4-oxobutanoic acids under the action of SOCl2. Their in vitro antibacterial and antifungal activities have been evaluated against reference strains and versus reference compounds. The so-called 'isoimides' 2a, 2b were totally inactive whereas some imides had low MICs for few bacteria and for few fungal microorganisms.

Syntheses, in vitro antibacterial and cytotoxic activities of a series of 3-substituted succinimides.

We have synthesized a series of 3-substituted succinimides and their in vitro antibacterial activities have been tested towards Gram-positive and Gram-negative bacteria from the ATCC collection. Some of them possess significant antibacterial activity against Gram-positive organisms (Staphylococcus aureus ATCC 25923 and Enterococcus faecalis ATCC 29212) but all are poorly active or inactive against Gram-negative organisms (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853). The compounds with the lowest minimal inhibitory concentrations (esters of 3-hydroxy succinimides) are also the most cytotoxic against green monkey Vero cell line (ATCC CCL-81) and could explain that perhaps apoptosis should be implicated in eukaryotic cell cytotoxicity of succinimides.

Structure-activity relationships of methylene or terminal side chain modified retinoids on the differentiation and cell death signaling in NB4 promyelocytic leukemia cells.

New structure-activity relationships of a series of methylene or side chain modified retinoids on NB4 acute promyelocytic leukemia cells are investigated. The differentiation- and apoptosis-inducing potential of these compounds is analyzed on the basis of their selective retinoic acid receptor binding profile.

Antifouling activities of N-substituted imides: antimicrobial activities and inhibition of Mytilus edulis phenoloxidase.

In the search for novel biodegradable antifouling agents, a series of imides (N-substituted maleimides and succinimides) have been synthesized. A large majority of N-substituted maleimides and succinimides showed an antimicrobial activity toward gram-positive and gram-negative bacteria and fungi of marine origin with minimal inhibition concentrations in the range of 6 to 24 microg/ml. The imides with an alkyl substituent showed higher activities than aromatic analogues, but structure-activity relationships were not clearly established.

Synthesis and antimicrobial activities of N-substituted imides.

In the field of our research programs concerning novel antimicrobial agents, a series of N-substituted imides was synthesized. These compounds were obtained by cyclization of amido-acids in acetic anhydride/sodium acetate or hexamethyldisilazane/zinc bromide for the hydroxy-aromatic derivatives. The hydroxy-alkyl maleimides were directly prepared by condensation of the corresponding amino-alcohol with maleic anhydride in boiling toluene.

Anorexia nervosa: slow regain of bone mass.

In a retrospective study of women aged 18-30 years, aimed at assessing factors associated with peak bone mass (PBM), 13 of 239 study cases reported having had anorexia nervosa. The mean total femoral and lumbar bone mineral density (BMD) values were not significantly lower in women who had had anorexia than in the pooled group (mean Z-scores of -0.60 and -0.

N-conjugates of 2,5-disubstituted pyrrole and glutathione. Evaluation of their potency as antioxidants against photosensitization of NCTC 2544 keratinocytes by excess endogenous protoporphyrin IX.

A novel glutathione compound in which the amino group has been derivatized by a 2,5-dimethyl pyrrole is shown to be very effective against cell photosensitization in vitro. Protoporphyrin IX either added to the medium or produced endogenously by incubation of NCTC 2544 keratinocytes with 5-aminolevulinic acid has been chosen as the photosensitizer. The antioxidant effectiveness of glutathione-pyrrole derivatives against protoporphyrin photosensitization depends critically on the type of 2,5 substitution on the pyrrole ring.

[Mass screening for colorectal cancer in France. Experience in 165,000 people in the department of Calvados].

Objectives: Screening for colorectal cancer is a major public health problem in France as in most developed countries. Several controlled trials are on-going in Europe. The aim of the study was to determine requirements for success of mass-screening for colorectal cancer in France.

Haemoccult test properties according to type and number of positive slides in mass screening for colorectal cancer.

Despite encouraging results from recent studies, there is still no consensus to undertake mass screening using the Haemoccult test in the general population. The success of mass screening for colorectal cancer depends among other things on Haemoccult test properties. In on-going screening programmes, the Haemoccult test consists of six slides and a test is considered positive if at least one slide is coloured.

Participants' characteristics in a French colorectal cancer mass screening campaign.

Background: Participation by the target population is clearly a key element in the success of mass screening programs for colorectal cancer. In France, involvement of general practitioners in test distribution is essential to reach a satisfactory participation rate, but other forms of recruitment also have to be organized. The aim of this study was to determine the influence of demographic characteristics such as sex, age, and place of residence on the participation rate in a French mass screening according to different recruitment methods.

[Objectives and means of screening of colorectal cancer].

Despite numerous publications on the subject, the debate over the merits of the various methods available for screening for colorectal cancer is continuing. Choice of the method depends on the patient being treated. In the present state of our knowledge, mass screening by Hemoccult, which is of low cost but of poor sensitivity and only fairly well accepted, cannot be used routinely but must be further evaluated and developed.

Glutathione peroxidase and glutathione reductase activities towards glutathione-derived antioxidants.

A new class of glutathione derivatives with antioxidant properties has been prepared by transformation of the NH2 group into a pyrrole ring with various substitutions at the 2 and 5 positions. Due to steric hindrance and/or hydrophobicity of the 2-5-disubstituted pyrrole ring, the reduced glutathione derivatives are poor substrates of the glutathione peroxidase and do not effectively compete with GSH. The oxidized glutathione derivatives are, in turn, relatively good substrates (Km = 1.

A pulse radiolysis study of one-electron oxidation and .OH radical reaction of a new class of antioxidants: 2,5 dimethylpyrrole--amino acid N-conjugates.

A new class of 2,5 dimethylpyrrole functionalized amino acid and peptide antioxidants has been synthesized. Pulse radiolysis studies have been carried out on these compounds to determine their reactivity in one-electron oxidation reactions with Br2- and (SCN)2-, as well as their reactivity toward the water radicals .OH and eaq-.

Biodistribution and excretion of a mixed fluorocarbon-hydrocarbon "dowel" emulsion as determined by 19F NMR.

To investigate the biodistribution, possible metabolism and excretion of mixed fluorocarbon-hydrocarbon "dowel" molecules used as stabilizers of fluorocarbon emulsions, we have prepared a 25% w/v emulsion of such a molecule, and quantitatively evaluated, by means of 19F NMR, its behavior in the blood and reticuloendothelial system (RES) of rats. C6F13CH = CHC10H21 (F6H10E) was emulsified using egg yolk phospholipids (EYP). The emulsion (F6H10E/EYP: 25/6% w/v) was injected intravenously into 33 Sprague Dawley female rats at a 3.

RP-HPLC peptide mapping methods for the analysis of recombinant human pro-urokinase.

Among the techniques available for the detection of protein structure variants such as single point mutations, RP-HPLC peptide mapping plays a key role owing to the high reproducibility of peptide retention times, determined as identity indexes. Because of the possible co-elution of some proteolytic fragments, an improvement of the array of information given by the technique can be achieved by setting up a series of experiments under hydrolytic conditions with different enzymes, followed by appropriate RP-HPLC gradient elutions. Such an experimental approach appears to be particularly useful in the examination of proteins with a high molecular weight, where the resulting RP-HPLC maps are complex.

[Leukocyte depletion of blood products and anti-HLA immunization].

HLA alloimmunization and subsequent refractoriness to platelet transfusions are frequent complications of transfusion therapy in patients with hematologic malignancies. Contaminating leukocytes in red cell and platelet concentrates are responsible for primary HLA alloimmunization. In many clinical trials, it has been demonstrated that the use of leukocyte-poor blood products prepared by filtration could reduce HLA-alloimmunization from 40% to 15%.

Involvement of general practitioners in mass screening. Experience of a colorectal cancer mass screening programme in the Calvados region (France).

Good compliance with screening programmes is essential and experience from ongoing studies points to the importance of involving general practitioners (GPs). The aim of this study was to evaluate factors influencing the participation of GPs in a screening programme, as well as acceptance of the test by the population. Fifty GPs were randomly chosen among the 117 practices of three districts in Calvados (France) where haemoccult test-based mass screening for colorectal cancer was underway.

[Descriptive modeling of the chemical structure-biological activity relations of a group of malonic polyethylenic acids as shown by different pharmacotoxicologic tests].

48 new polyethylenic-malonic acids have been submitted to an antimicrobial and antifungal screening. After a suitable recording, the experimental results were analyzed according to two mathematical multivariate analysis using a computer process i.e.

Assessment of portal contribution to liver perfusion by quantitative sequential scintigraphy and Doppler ultrasound in alcoholic cirrhosis. Diagnostic value in the detection of portal hypertension.

To assess the portal contribution to liver perfusion, we carried out quantitative sequential scintigraphy in 110 patients with alcoholic cirrhosis (22 Child-Pugh class A, 39 class B, 49 class C) and 15 normal subjects. Duplex Doppler ultrasound found a type of intrahepatic circulation that made the standard scintigraphic procedure inaccurate in four cases of cirrhosis, which were reevaluated. Portal contribution to liver perfusion was lower in cirrhotics than in normal subjects (48.
