OBJECTIVES: To describe a new, simple surgical technique for the treatment of female stress urinary incontinence (SUI) and to evaluate its feasibility. METHODS: We have developed a novel surgical treatment of SUI, the transobturator inside-out tension-free urethral suspension, which uses specifically designed surgical tools, and in which a synthetic tape is passed from underneath the urethra, through the obturator foramens, towards the thigh folds, without entering the pelvic region at any time during the procedure. The tape is positioned without tension under the junction between mid and distal urethra. RESULTS: The procedure was carried out in 107 consecutive patients (mean age: 62 years) using the same operative protocol in all case subjects, independently of the patient's size and weight. Mean operative time was 14 min (range: 7-20) in case of isolated SUI treatment. No bladder or urethral injuries and no vascular (hematoma or bleeding) or neurological complications were encountered. CONCLUSIONS: The results of this study indicate that our novel transobturator inside-out surgical technique for treating SUI is feasible, accurate, and quick. This technique avoids damage to the urethra and bladder and, therefore, makes cystoscopy not necessary. Further prospective studies are currently ongoing to determine the efficacy of our new surgical approach for treating SUI. [less ▲]

Background: Diabetic nephropathy (DN) affects about 30% of patients with type 1 diabetes (T1D) and contributes to serious morbidity and mortality. So far only the 3q21–q25 region has repeatedly been indicated as a susceptibility region for DN. The aim of this study was to search for new DN susceptibility loci in Finnish, Danish and French T1D families. Methods and Results: We performed a genome-wide linkage study using 384 microsatellite markers. A total of 175 T1D families were studied, of which 94 originated from Finland, 46 from Denmark and 35 from France. The whole sample set consisted of 556 individuals including 42 sib-pairs concordant and 84 sib-pairs discordant for DN. Two-point and multi-point non-parametric linkage analyses were performed using the Analyze package and the MERLIN software. A novel DN locus on 22q11 was identified in the joint analysis of the Finnish, Danish and French families by genome-wide multipoint nonparametric linkage analysis using the Kong and Cox linear model (NPLpairs LOD score 3.58). Nominal or suggestive evidence of linkage to this locus was also detected when the three populations were analyzed separately. Suggestive evidence of linkage was found to six additional loci in the Finnish and French sample sets. Conclusions: This study identified a novel DN locus at chromosome 22q11 with significant evidence of linkage to DN. Our results suggest that this locus may be of importance in European populations. In addition, this study supports previously indicated DN loci on 3q21–q25 and 19q13. [less ▲]

A new three-enzyme reaction cycle consisting of sucrose synthase, UDP glucose 4‘-epimerase, and human β-1,4-galactosyltransferase was established for the synthesis of N-acetyllactosamine (LacNAc) with in situ regeneration of UDP galactose. We found that UDP glucose 4‘-epimerase is reductively inactivated in the presence of UMP and acceptor substrates of β-1,4-galactosyltransferase. Reactivation of UDP glucose 4‘-epimerase by the transition state analogues dUDP or dTDP 6-deoxy-d-xylo-4-hexulose in combination with the repetitive batch technique enabled us to use the native enzymes for 11 days in this cycle. With 10 U of sucrose synthase, 5 U of UDP glucose 4‘-epimerase, and 1.25 U of β-1,4-galactosyltransferase, 594 mg of LacNAc could be synthesized. N-Acetyllactosamine was also subsequently converted to Neu5Acα2,6Galβl,4GlcNAc with α-2,6-sialyltransferase and CMP-Neu5Ac. [less ▲]

Drug-induced toxic epidermal necrolysis (TEN) is a life-threatening disease characterized by extensive destruction of the epidermis. It apparently results from the formation of specific toxic drug metabolites by the keratinocytes. The mortality rate which averages 25-30% is mainly due to secondary septicemia, and to ionic and metabolic disturbances following loss of epidermal integrity. Apoptosis is the likely mechanism leading to massive keratinocyte death in TEN. Dysregulations in the tumor necrosis factor-alpha (TNF-alpha) pathway, CD95 system (Fas ligand, CD95L; Fas receptor, CD95R) and calcium homeostasis in the epidermis are involved in this apoptotic process. An active role has also been ascribed to T lymphocytes, macrophages and factor XIIIa-positive dermal dendrocytes. Despite progress, treatment of TEN remains controversial. In the past, systemic glucocorticoids were used in order to target the inflammatory reaction in TEN. However, there was no evidence for improvement of the healing process, while corticosteroids worsened the prognosis by increasing the risk of septicemia. Only a few cases have been treated with other drugs including cyclophosphamide, pentoxyfilline, thalidomide, anti-TNF-alpha antibodies and cyclosporin A. In the recent past, some TEN patients were treated with intravenous human immunoglobulins (IVIG). The rationale for such a treatment was to block the CD95 system on keratinocytes. The early promising clinical results of IVIG treatment in TEN were subsequently challenged. This review compares the effectiveness and drawbacks of the major drugs presently used in TEN treatment. Some future prospects in TEN management are also discussed. [less ▲]

Ehlers-Danlos syndrome (EDS) type VIIC, or dermatosparactic type, is a recessively inherited connective tissue disorder characterized, among other symptoms, by an extreme skin fragility resulting from mutations inactivating ADAMTS-2, an enzyme excising the aminopropeptide of procollagens type I, II, and III. All previously described mutations create premature stop codons leading to a marked reduction in the level of mRNA. In this study, we analyzed the ADAMTS2 cDNA sequences from five patients displaying clinical and/or biochemical features consistent with a diagnosis of either typical or potentially mild form of EDS type VIIC. Three different alterations were detected in the two patients with typical EDS type VIIC. The first patient was homozygous for a genomic deletion causing an in-frame skipping of exons 3-5 in the transcript. In the second patient, the allele inherited from the mother lacks exon 3, generating a premature stop codon, whereas the paternal allele has a genomic deletion resulting in an in-frame skipping of exons 14-16 at the mRNA level. Although the exons 3-5 or 14-16 encode protein domains that have not been previously recognized as crucial for ADAMTS-2 activity, the aminoprocollagen processing was strongly impaired in vitro and in vivo, providing evidence for the requirement of these domains for proper enzyme function. The three other patients with a phenotype with some resemblance to EDS type VIIC only had silent and functionally neutral variations also frequently found in a normal population. [less ▲]

Ring-opening polymerization (ROP) and ring-opening metathesis polymerization (ROMP) of an unsaturated epsilon-caprolactone, 6,7-dihydro-2(3H)-oxepinone (DHO2), are alternative routes to produce unsaturated aliphatic polyesters with the same molecular structure. Polymerization of DHO2 initiated by Al isopropoxide in toluene at room temperature or at 0°C proceeds by a coordination-insertion mechanism, although intramolecular transesterification takes place beyond complete monomer conversion. The molecular weight distribution is narrow as long as monomer conversion does not exceed 90%. Ring-opening metathesis polymerization of DHO2 initiated by Schrock's Mo-based catalyst, 1, at 60°C allows higher molecular weight unsaturated polyester to be prepared, even though an intramolecular side reaction also operates. The structure of poly(DHO2) synthesized by ROP and ROMP is the same, as confirmed by 1H, 13C NMR, and FT-IR spectra. Copolymers of DHO2 with norbornene, cis-cyclooctene, and 1,5-cyclooctadiene have been successfully prepared. [less ▲]

Vaccinia virus (VV) produces two antigenically and structurally distinct infectious virions, intracellular mature virus (IMV) and extracellular enveloped virus (EEV), which bind to unidentified and possibly different cellular receptors. Studies of VV binding have been hampered by having two infectious virions and by the rupture of the EEV outer membrane in the majority of EEV virions during purification. To overcome these problems, we have developed a novel approach to study VV binding that is based on confocal microscopy and does not require EEV purification. In this assay, individual virus particles adsorbed to the cell are simultaneously distinguished and quantified by double immunofluorescence labelling with antibody markers for EEV and IMV. By this method, we show unequivocally that IMV and EEV bind to different cellular receptors. Three independent observations allow this conclusion. First, the efficiencies with which IMV and EEV bind to different cell lines are unrelated; second, cell surface digestion with some enzymes affects IMV and EEV binding differently; and third, the binding of a monoclonal antibody to cells prevents IMV binding but not EEV binding. This technique may be widely applicable for studying the binding of different viruses. [less ▲]

BACKGROUND: Miconazole nitrate is a time-honored antifungal of the imidazole class. OBJECTIVE: To revisit the various aspects of action of the drug in a dermatologic setting. METHOD: Review of the current peer-reviewed publications. RESULTS/CONCLUSION: Miconazole essentially inhibits 14alpha-demethylase, an enzyme required for the biosynthesis of ergosterol, which is the main sterol constituent of fungal cell membranes. Hence, toxic methylated sterols accumulate. Synthesis of triglycerides and phospholipids is also affected. In addition, miconazole also exhibits other ancillary mechanisms of action that probably participate in the therapeutic efficacy of the drug. The oxidative and peroxidative enzyme activities are altered leading to an intracellular build up of a toxic concentration of hydrogen peroxide. This may contribute to the deterioration of subcellular organelles and to cell necrosis. Farnesol synthesis is stimulated in Candida spp. leading to the prevention of yeast-to-mycelium formation. Overall, miconazole is fungistatic through its effect on ergosterol biosynthesis, but it may also have a fungicidal effect against a number of fungal species due to its effect on hydrogen peroxide accumulation. In addition, miconazole is active against a series of Gram-positive bacteria and has been shown to help the repair of the skin barrier function and to help mitigate some inflammatory cell reactions (such as in acne). To conclude, miconazole exerts multi-pronged effects both against pathogenic fungi and on skin physiology. [less ▲]
