Reconstruction of Nasal Alar Defects with Freestyle Facial Artery Perforator Flaps

2014

In 2009, we have described the use of freestyle facial artery perforator flaps for one-stage nose reconstruction. Since then, several articles have reported the use of facial artery perforator flaps for nose reconstruction. The purpose of this article is to provide an update of the published technique after 10 years of experience. Since 2004, 21 patients have been treated with a freestyle facial artery perforator flap for one-stage reconstruction of the nasal ala. The flaps were 16 propellers, 4 V-Y, and 1 island transposition. A single venous congestion leading to a minor flap tip necrosis and a wound dehiscence was observed. All other flaps healed uneventfully. The V-Y design and multiple…

Sentinel-node biopsy in early stage ovarian cancer: a prospective multicentre study (SELLY)

2019

BackgroundSystematic para-aortic and bilateral pelvic lymphadenectomy is included in the standard comprehensive surgical staging in presumed early epithelial ovarian cancer. No prospective randomized evidence suggests it has potential therapeutic value, and related morbidity is not negligible.Primary Objective(s)To assess sensitivity, safety, and feasibility of the sentinel lymph node technique in identifying the presence of lymph node metastases in patients with early stage epithelial ovarian cancer.Study HypothesisSentinel lymph node detection with indocyanine green can accurately predict nodal status in a cohort of women with early stage epithelial ovarian cancer.Trial DesignThe SELLY tr…

The evolution of breast cancer mortality and morbidity in Spain (1977?1988)

1996

A study of breast cancer mortality and cancer morbidity has been carried out in Spain recently for the period 1977-1988, covering the population of the 17 Autonomous Communities and 50 provinces of the country. Data was obtained from INE, Instituto Nacional de Estadística (National Institute of Statistics), with age standardization using the indirect method. The different Autonomous Communities and provinces were compared in order to establish possible significant differences. The crude mean mortality rate was 21 cases per 100,000 inhabitants/year; Las Palmas, Gerona, Barcelona, the Balearic Islands, Navarra and Zaragoza have the highest mortality rates, with a proportional increment of 54%…

Glutathione, GlutathioneS-Transferase α and π, and Aldehyde Dehydrogenase Content in Relationship to Drug Resistance in Ovarian Cancer

1997

Glutathione, glutathione S-transferases alpha and pi, and aldehyde dehydrogenase are associated with resistance to carboplatin and/or cyclophosphamide in cell lines. Therefore, we examined whether the expression of these factors in ovarian cancer tissue specimens is associated with resistance of the patients to combination chemotherapy with cyclophosphamide/carboplatin. Ovarian cancer tissue specimens were taken intraoperatively from 139 patients and frozen in liquid nitrogen, and the contents of glutathione S-transferases alpha and pi, total glutathione, and aldehyde dehydrogenase activity were determined. No association between the levels of glutathione S-transferases alpha and pi or alde…

Estradiol, progesterone, 17-hydroxyprogesterone, androstenedione and CA125 in patients with ovarian carcinoma.

1992

Estradiol, progesterone, 17-hydroxyprogesterone, androstenedione and CA125 were assayed in 25 women (12 oophorectomized before entering the study) with ovarian carcinoma. The data from patients were ordered according to the presence or absence of the gonads. The patients with ovaries (Group A) showed significantly higher levels of estradiol (p less than 0.01), progesterone (p less than 0.01) and 17-hydroxyprogesterone (p less than 0.01) than controls. This difference was not observed between oophorectomized patients (Group B) and controls. CA125 levels were significantly higher in patients that in controls (p less than 0.001) irrespective of the ovarian status of the patients. Eleven patien…

Specific mutations of the RET proto-oncogene are related to disease phenotype in MEN 2A and FMTC.

1994

We have analysed 118 families with inherited medullary thyroid carcinoma (MTC) for mutations of the RET proto-oncogene. These included cases of multiple endocrine neoplasia types 2A (MEN 2A) and 2B (MEN 2B) and familial MTC (FMTC). Mutations at one of 5 cysteines in the extracellular domain were found in 97% of patients with MEN 2A and 86% with FMTC but not in MEN 2B patients or normal controls. 84% of the MEN2A mutations affected codon 634. MEN 2A patients with a Cys634 to Arg substitution had a greater risk of developing parathyroid disease than those with other codon 634 mutations. Our data show a strong correlation between disease phenotype and the nature and position of the RET mutatio…

Characteristics and patterns of care of endometrial cancer before and during COVID-19 pandemic

2021

Objective Coronavirus disease 2019 (COVID-19) outbreak has correlated with the disruption of screening activities and diagnostic assessments. Endometrial cancer (EC) is one of the most common gynecological malignancies and it is often detected at an early stage, because it frequently produces symptoms. Here, we aim to investigate the impact of COVID-19 outbreak on patterns of presentation and treatment of EC patients. Methods This is a retrospective study involving 54 centers in Italy. We evaluated patterns of presentation and treatment of EC patients before (period 1: March 1, 2019 to February 29, 2020) and during (period 2: April 1, 2020 to March 31, 2021) the COVID-19 outbreak. Results M…
