Agro-ecological benefits of faba bean for rainfed Mediterranean cropping systems
2017
This paper reviews the main results from a set of experiments carried out in a semiarid Mediterranean environment during the past 25 years on faba bean (<em>Vicia faba</em> L.), a crop traditionally grown in southern Italy and Sicily under rainfed conditions. These experiments focused on the residual effects of faba bean on subsequent crop(s) and assessment of the nitrogen (N) balance during the crop cycle, paying attention to both the environmental release of N (losses via volatilisation and denitrification) and estimates of N2 fixation as influenced by tillage system, intercropping, and presence/absence of mycorrhizal inoculum. Faba bean relied on N2 fixation more than other g…
Factors associated with epiphora following orbital‐sparing maxillectomy via modified Weber–Ferguson incision with lower blepharoplasty
2021
Purpose The aims of the study were to estimate the frequency of epiphora and to identify factors associated with epiphora after orbital-sparing maxillectomy via modified Weber-Ferguson incision with lower blepharoplasty (OSOSM-MWFILB). Methods We performed a retrospective cohort study enrolling a sample derived from the patient population undergoing OSM-MWFILB over a 7-year period. The predictor variables were grouped into demographic, related health status, anatomic, tumor-specific, and therapeutic categories. The primary outcome variable was the presence of postmaxillectomy epiphora (PME). Descriptive, univariate, and multivariate regression mixed-effect models were computed. Results The …
THE USE OF ARGENTUM-QUARTZ SOLUTION IN PRIMARY OR RECURRENT PERIANAL FISTULAS: FIRST EXPERIENCE ON THREE CASES
2019
Primary perianal fistulous pathology represents a painful condition often noticeable in patients affected by Crohn's disease or Ulcerative colitis. It causes difficult defecation and can evolve in perianal abscess that should be urgently ascertained and drained. The present work aims to propose Argentum-Quartz® as valid non-surgical therapeutic treatment in order to reach a more comfortable perianal fistula healing. In fact, our preliminary data allow us to consider Argentum Quartz® ideally employable for treatment of perianal fistulas associated or not with IBDs, representing a reliable sphincter-sparing solution.
Treatment of cT1a Renal Tumours in Germany: A Nationwide Survey.
2015
<b><i>Objective:</i></b> To identify clinical parameters influencing German urologists treating cT1a renal tumours, we performed a nationwide survey among members of the German urological associations (DGU and BDU). <b><i>Material and Methods:</i></b> In spring 2012, DGU and BDU members were invited to complete our survey. For 8 cases and 3 index patients, participants were asked about their preferred treatment. Multivariate analyses were used to identify significant parameters leading the responders to favour radical nephrectomy (RN) over nephron sparing surgery (NSS) as well as active surveillance (AS) over invasive treatment. <b><i…
Elective nephron sparing surgery for renal cell carcinoma larger than 4 cm.
2007
Elective nephron sparing surgery is established as an alternative to radical nephrectomy for renal cell carcinoma if tumors are small (4 cm or less, stage T1a). We compared outcomes in patients with renal cell carcinoma 4 cm or less (small) vs more than 4 cm (large) who were treated with nephron sparing surgery.Between 1979 and 2006, 618 patients underwent elective nephron sparing surgery at our institution. Of these patients 474 (76.7%) had renal cell carcinoma, which was 4 cm or less in 372 (78.5%) and more than 4 cm in 102 (21.5%). Followup was 4.7 (range 0.1 to 23.9) years for small and 4.7 (range 0.1 to 24.1) years for large tumors. Cancer specific survival and local recurrence free su…
Soft palate preservation after tumor resection with transoral laser microsurgery
2012
Background: Management and preservation of the soft palate is dependent on clinical stage and tumor histology. However, available literature is scarce regarding the palate preservation with the use of laser CO 2 . Objectives : We report the results obtained after management with laser surgery and soft palate preservation in three patients with salivary gland neoplasms. Method: Three patients with minor salivary gland tumors were treated by means of transoral laser microsurgery. All tumors were assessed using magnetic resonance imaging. All tumors were >3 cm. Soft palate function was preserved and reconstruction was performed with primary closure. Patients began oral feeding the same day and…
Sequential boost in neoadjuvant irradiation for T3N0-1 rectal cancer: long-term results from a single-center experience.
2016
Purpose To evaluate the influence of radiation dose on tumor regression grade (TRG) and sphincter preservation rate in a series of cT3N0-1 rectal cancer patients treated with neoadjuvant chemoradiotherapy (CT-RT) with or without a sequential radiation boost. Materials and methods Between May 2002 and September 2013, 116 cases were eligible for retrospective evaluation. Radiotherapy was delivered for a total dose of 45 Gy (no boost arm) or 50.4 Gy (boost arm). TRG was evaluated with the Dworak scale. Results Median follow-up was 62 months (range, 12-138 months). The 5-year overall survival and local control rates were 72% and 93%, respectively. Fifty-five patients (47%) were treated with a s…
Thoracic shaping technique to avoid residual space after extended pleurectomy/decortication
2013
Extended pleurectomy/decortication or radical pleurectomy is defined as a lung-sparing surgical procedure for malignant pleural mesothelioma. A significant size mismatch between the thoracic cavity and the reduced size of the remaining lung might occur as a result of multiple resections at different sites and lead to residual thoracic space. Residual thoracic space and significant air leakage might result in postoperative complications. A simple technique of diaphragm reconstruction to avoid the residual thoracic space and to reduce the incidence of postoperative complications is described.
Features Associated with Recurrence Beyond 5 Years After Nephrectomy and Nephron-Sparing Surgery for Renal Cell Carcinoma: Development and Internal V…
2014
Background: Approximately 10-20% of recurrences in patients treated with nephrectomy for renal cell carcinoma (RCC) develop beyond 5 yr after surgery (late recurrence). Objective: To determine features associated with late recurrence. Design, setting, and participants: A total of 5009 patients from a multicenter database comprising 13 107 RCC patients treated surgically had a minimum recurrence-free survival of 60 mo (median follow-up [FU]: 105 mo [range: 78-135]); at last FU, 4699 were disease free (median FU: 103 mo [range: 78-134]), and 310 patients (6.2%) experienced disease recurrence (median FU: 120 mo [range: 93-149]). Interventions: Patients underwent radical nephrectomy or nephron-…
Intraoperative Monitoring of Bladder and Internal Anal Sphincter Innervation: A Predictor of Erectile Function following Low Anterior Rectal Resectio…
2013
<b><i>Background:</i></b> The objective was to investigate whether two-dimensional intraoperative neuromonitoring (IONM) of pelvic autonomic nerves has the potential to predict erectile function (EF) following surgery for rectal cancer. <b><i>Methods:</i></b> A consecutive series of 17 sexually active male rectal cancer patients undergoing IONM-based nerve-sparing low anterior rectal resection were evaluated prospectively. IONM was performed by electric stimulation of the pelvic splanchnic nerves with concomitant electromyography of the internal anal sphincter and cystomanometry. Sexual function was assessed using a validated questionnaire. &l…
