Abstract
A national audit focused on laparoscopic appendectomy was promoted by the Italian Association of Hospital Surgeons (ACOI). Four-hundred and sixty surgical practices received an e-mail ...questionnaire. Data concerning epidemiology, timetable, surgeon's age, selection of patients, laparotomic conversion, behaviour in the case of a normal appendix, and technical aspects were investigated. The response rate was 51.7%. The median number of appendectomies performed is 50-100 each year in a surgery ward. Laparoscopic operations are very common (93%), but mostly performed in less than 50% of the observed cases. There is no significant difference between the number of operations during the day vs. at night, and they are performed by a limited (<30%) group of surgeons, equally composed of physicians aged above and below 40. The majority of surgeons adopt an "all comers" policy regarding laparoscopic appendectomy, including selected older patients (>70 years old). There are no standard indications for conversion, while the behaviour in the presence of a normal appendix is generally removal. Even if laparoscopic appendectomy is not yet considered a gold standard, it is widely diffused in Italy, and the audit's data show different behaviours between subgroups.
Radioguided-surgery has been recently proposed in patients with clinically occult breast lesions. This study aimed to evaluate the feasibility of correctly locating and eradicating, by a single ...intralesional injection of a radiotracer, any breast lesion and, in the case of malignancy, to perform simultaneous sentinel lymph node (SLN) biopsy procedure.
Sixty-three women with early breast lesions were enrolled: 42 were invasive carcinomas, 16 in situ ductal carcinomas (DCIS) and 5 fibroadenomas.
Scintigraphic images clearly identified the lesions in all patients while SLN/s were evident in 88% of them. At surgery all the breast lesions were easily radiolocalized and eradicated with minimum surgical trauma and, for those patients with invasive carcinomas, the SLN technique was performed in 86% of them. No skip metastases were found.
A single intralesional administration of radiotracer is an easy and reliable procedure to simultaneously locate and remove both the non-palpable breast lesion and the SLN when primary malignancy was intraoperatively confirmed.
An efficient protocol for stereo- and regiocontrolled synthesis of small polyfunctional molecules is presented. The stereospecific addition of PhSeCl to 2,5-dihydro-2,5-dimethoxy-furan
1 in solvents, ...such as methylene chloride and methanol, gives cyclic and linear acetals
2 and
3, depending on the solvent used. Emphasis is given to the regiocontrolled hydrolysis of acetal groups for the preparation of stereodefined and highly functionalized C
4 synthons, such as
8, 9 and
13.
