RESUMEN

INTRODUCTION: Oncoplastic breast surgery has evolved the surgical treatment of breast cancer over the past two decades. This practice still lacks validation and poses several dilemmas in terms of safety, local and systemic control, timing of adjuvant treatments and cost-effectiveness. Our case series investigates the effects of a reduced surgical complexity on cosmetic results and quality of life. METHODS: We treated 76 consecutive patients affected by early stage breast cancer from January 2016 to April 2017. We employed a decision support system to assist the final shared decision making. The communication process before surgery included new specific information on recent evidence about local control of disease and outcomes after multimodality treatment. In order to estimate the oncoplastic complexity, we created a new score based on scars, bilateral procedures and type and timing of reconstructions. We compared the outcomes of this series to that of a previous one from the same institution. RESULTS: The medium complexity score (CS) in the current series was significantly lower compared to that of the previous series (medium CS cohort 1 = 3.1 vs medium CS cohort 2 = 1.51; p = 0.001). Complications according to Clavien-Dindo classification did not vary significantly between the two series (p = 0.7). The increased use of primary systemic treatment did not translate into a significantly lower mastectomy rate (cohort 1 = 20% vs cohort 2 = 16%; p = n.s.). There was no significant difference in breast deformities after breast conserving surgery (p = 0.2). The BCCT.Core demonstrated a 67.1% occurrence of "good" results. Quality of life in patients who underwent breast-conserving surgery measured using the Breast-Q demonstrated similar results in the pre-post-op assessment. CONCLUSIONS: This study hypothesizes that a proper information may impact on patient's decisions and may reduce surgical complexity. This reduction likely has no effects on the main surgical outcomes estimated using standard tools. More investigations should be performed on a larger multi-institutional scale to confirm these conclusions.

RESUMEN

Automated karyotype analyses and sequence of rDNA spacers have been analysed for the species belonging to sections Atossa, Microcarinae, Wiggersia and Vicia. Karyomorphological parameters, based on Rec, Syi and TF% indices, have been determined and evidenced that, in term of symmetry, the karyotype of Vicia lathyroides was the most asymmetric one. A multivariate analysis using 34 karyological parameters, in addition to the symmetry indices, has been carried out and the corresponding dendrogram of linkage distances showed six different groups. Molecular investigations on the inclusive group in study by employing ITS DNA sequences indicated a different pattern of relationships. The cladistic analysis combining the molecular data set with karyological parameters evidenced that the species of sections Vicia and Atossa join closely to each other in a paraphyletic group, which includes the monophyletic section Wiggersia. Therefore, our karyological and molecular data provide information about the phylogenetic position of the analysed species inside the subgenus Vicia and are discussed in relation to previous results obtained by morphology, isozymes and ribosomal genes analyses.

RESUMEN

Vicia oroboides, a rare taxon belonging to section Atossa of subgenus Vicia, was recovered and analysed by means of cytological and karyological methods with the aim of both characterising this species and integrating our knowledge on phylogeny of subgenus Vicia. Automated karyotype analysis and nuclear DNA content have been determined after Feulgen's reaction; chromosome banding was performed by fluorochrome staining to evidence heterochromatic blocks along the chromosome complement. The chromosome number is in line with the values of the species of section Atossa; the GC- and AT-rich sites were identified by CMA and DAPI staining. Karyomorphological parameters, based on symmetry indices, provide information about the phylogenetic position of this species inside the subgenus Vicia. DNA content is reported for the first time.

RESUMEN

One standard and two reconstructed barley karyotypes were used to study the influence of chromosomal rearrangements on the distribution pattern of DNA methylation detectable at the chromosome level. Data obtained were also compared with Giemsa N-bands and high gene density regions that had been previously described. The effect of chromosomal reconstruction in barley seems to be decidedly prominent in the repositioning of genomic DNA methylation along metaphase chromosomes. In comparison to the standard karyotype, the DNA methylation pattern was found to vary not only in the reconstructed chromosomes but also in the other chromosomes of the complements not subjected to structural alterations. Moreover, differences may occur between corresponding regions of homologues. Some specific chromosomal bands, including the nucleolus-organizing regions, showed a relative constancy in the methylation pattern, but this was not the case when the two satellites were combined by translocation in chromosome 6H(5H) of line T-30. Our results suggest that epigenetic changes like DNA methylation may play an important role in the overall genome reorganization following chromosome reconstruction.

RESUMEN

Vicia esdraelonensis, a rare taxon belonging to section Hypechusa of subgenus Vicia, was recovered and analyzed by cytological, karyological, and molecular methods, with the aim of both characterizing this species and furthering our knowledge of the phylogeny of subgenus Vicia. Automated karyotype analysis, nuclear DNA content, and chromatin organization were determined by the Feulgen reaction, as well as chromosome banding after double staining with 4',6-diamidino-2-phenylindole (DAPI) and chromomycin A3. The chromosome number and the nuclear DNA content were in agreement with the values of the species of section Hypechusa. The GC- and AT-rich preferential sites were determined by chromomycin A3 and DAPI staining. Karyomorphological parameters indicated that V. esdraelonensis is in an intermediate position in the spatial representation of the species of section Hypechusa on the basis of symmetry indices, as well as in the dendrogram of linkage distance constructed on 37 chromosome parameters. Molecular data based on internal transcribed spacer sequences show that V. esdraelonensis can doubtlessly be included in section Hypechusa and document its closeness to V. noeana. A cladistic analysis combining the molecular data set with karyological characters is also reported. Karyological, cytological, and molecular data allow characterization of the V. esdraelonensis genome and provide information about the phylogenetic position of this species within the Hyrcanicae series of section Hypechusa.

RESUMEN

Nuclear DNA contents, automated karyotype analyses, and sequences of internal transcribed spacers from ribosomal genes have been determined in the species belonging to section Hypechusa of the subgenus Vicia. Karyomorphological results and phylogenetic data generated from the comparison of rDNA (genes coding for rRNA) sequences showed that sect. Hypechusa is not monophyletic; however, some monophyletic units are apparent (one including Vicia galeata, V. hyrcanica, V. noeana, and V. tigridis, another including V. assyriaca, V. hybrida, V. melanops, V. mollis, and V. sericocarpa), which partly correspond to morphology-based infrasectional groups. The relationships among these species and the species in sections Faba, Narbonensis, Bithynicae, and Peregrinae have been also investigated.

RESUMEN

Nuclear DNA contents, automated karyotype analyses, and sequences of rDNA spacers have been determined for the species of Vicia belonging to sect. Peregrinae, as well as for V. mollis. The phylogenetic data generated from the comparison of rDNA sequences and karyomorphological results would both indicate that Vicia mollis is a sister group to sect. Peregrinae. The relationships among the species belonging to the Peregrinae section and species enclosed in sections Faba, Narbonensis, and Bithynicae have been also investigated: a clade including V. mollis and sect. Peregrinae is a sister group to a clade including V. bithynica and sect. Narbonensis. With our choice of outgroup, Vicia faba (including subsp. paucijuga) is external to the above mentioned inclusive group.

RESUMEN

Current pesticide exposure levels can induce a state of sensitization in exposed workers and only in exceptional situations cause severe intoxication. Three cases are reported--one suffering from urticaria/angio-edema, one from asthma and the other from oculo-rhinitis. Only one subject was atopical. The substances to which sensitization was found were Cynoxamil, Mancozeb, Thiophanate, Seccatutto for the first case, Paraquat for the second and Dodine for the third subject. The results suggest the need to extend allergological tests also to pesticides when workers, or subjects in any case exposed, show clinical signs with suspected immunological pathogenesis. Furthermore, in order to reduce the number of new cases of pesticide allergy, a more severe control also of subjects exposed to low doses is proposed.
