Pattern of recurrence and survival after D2 right colectomy for cancer: is there place for a routine more extended lymphadenectomy?

Background: Conventional Right Colectomy with D2 lymphadenectomy (RC-D2) currently represent the most common surgical treatment of right-sided colon cancer (RCC). However, whether it should be still considered a standard of care, or replaced by a routine more extended D3 lymphadenectomy remains unclear. In the present study, we aim to critically review the patterns of relapse and the survival outcomes obtained from our 11-year experience of RC-D2.

A study on biorelevant calciprotein particles: Effect of stabilizing agents on the formation and crystallization mechanisms.

Hypothesis: Calciprotein particles (CPPs) are endogenous nanoparticles consisting of hybrid mineral-organic colloidal complexes made of calcium phosphates and Fetuin-A (Fet-A), a protein that in physiological conditions binds to amorphous calcium phosphate forming primary CPP (CPP1). CPP1 can crystallize resulting in hydroxyapatite-based secondary CPP (CPP2) that can eventually precipitate leading to vascular calcifications. The treatment of patients with molecules and ions that delay the amorphous-to-crystalline transition has shown promising results from a clinical perspective, but the study of their mechanism of action has not been thoroughly examined so far.

Ensemble deep learning for the prediction of proficiency at a virtual simulator for robot-assisted surgery.

Background: Artificial intelligence (AI) has the potential to enhance patient safety in surgery, and all its aspects, including education and training, will derive considerable benefit from AI. In the present study, deep-learning models were used to predict the rates of proficiency acquisition in robot-assisted surgery (RAS), thereby providing surgical programs directors information on the levels of the innate ability of trainees to facilitate the implementation of flexible personalized training.

Methods: 176 medical students, without prior experience with surgical simulators, were trained to reach proficiency in five tasks on a virtual simulator for RAS.

Synchronous squamous cell carcinoma and papillary thyroid carcinoma arising from the thyroglossal duct remnant: Case report and a review of the literature.

Squamous cell carcinoma and papillary thyroid carcinoma simultaneously spreading from the thyroglossal duct remnant (TGDR) is a very rare event. The recognition of this condition allows a correct management and treatment, offering the best chances of cure to the patient. We describe the case of a 42-year-old woman who noticed a right-sided lump in her neck.

Discussions about palliative sedation in hospice: Frequency, timing and factors associated with patient involvement.

Objective: To investigate whether and when palliative sedation was discussed with hospice patients with cancer and/or with their families and factors associated with patient involvement in such discussions.

Methods: Medical records of all patients with cancer who died in an Italian hospice in 2014-2015 (N = 326) were retrospectively reviewed. Multiple logistic regression was used to assess the association between patients' characteristics and palliative sedation discussion with the patient versus palliative sedation discussion only with the family.

The Relationship between Intraoperative Rupture and Recurrence of Pediatric Ovarian Neoplasms: Preliminary Observations.

Study Objective: We investigated whether rupture increased the recurrence rate of pediatric ovarian neoplasms.

Design: 20-year single-institution retrospective study.

Setting: Tertiary, free-standing, university children's hospital.

Spigelian hernia in a 14-year-old girl: a case report and review of the literature.

Spigelian hernia (SH) is a surgical rarity in children, which occurs through slit-like defects in the anterior abdominal wall adjacent to the semilunar line, the convexity lateral line which joins the nine ribs to the pubic tubercle and signs the limit between the muscular and aponeurotic portion of transversus abdominis muscle. As there are no specific symptoms and signs, the diagnosis is difficult, especially in children. We report a case of SH that comes to our observation: a 14-year-old girl presented recurrent abdominal pain associated to intermittent palpable mass in the paraumbilical region.

Effects on normalized testicular atrophy index (TAIn) in cryptorchid infants treated with GnRHa pre and post-operative vs surgery alone: a prospective randomized trial and long-term follow-up on 62 cases.

Purpose: The aim of this study was to investigate the effects of gonadotropin releasing hormone analog (GnRHa) therapy on normalized testicular atrophy index (TAIn) using gonadorelin before and after orchiopexy.

Methods: 62 infants with 87 undescended testes (UDT) were prospectively assigned to two homogeneous groups according to age, position of UDT and TAIn. The patients were randomized to receive either orchiopexy alone or orchiopexy combined with GnRHa as nasal spray at 1.

Treatment of ovarian lesions in children and adolescents: a retrospective study of 130 cases.

In this study, we analyze the management of ovarian masses in a total of 130 children surgically treated for 137 ovarian lesions (7 bilateral). The most frequent symptoms were chronic (52.3%) and acute (25.

Primary hyperparathyroidism: fifth parathyroid intrathymic adenoma in a young patient.

The clinical case described in this paper deals with a young female patient affected by primary hyperparathyroidism caused by an ectopic parathyroid adenoma of a supernumerary intrathymic parathyroid. The patient had hypercalcemia, in association with increased levels of parathormone, but was otherwise asymptomatic. Genetics tests for mutation of the MEN1, HRPT2, and CaSR genes were negative.

Adnexal torsion in children and adolescents: new trends to conservative surgical approach -- our experience and review of literature.

The purpose of this study is to discuss the surgical treatment for ovarian torsion in children and adolescents with a focus on the procedures of adnexal conservation surgery and its frequency in the literature of the last 10 years. We retrospectively reviewed the medical charts of 127 operative ovarian lesions including 30 ovarian torsions (23.6%) treated in two pediatric centers over a 10-year period.

The role of tumor markers in the surgical approach of ovarian masses in pediatric age: a 10-year study and a literature review.

Purpose: The purpose of this study was to detect the role of serum tumor markers in the differential diagnosis and in the choice of the surgical treatment of ovarian lesions in pediatric age.

Methods: We retrospectively reviewed medical charts of all pediatric girls operated in two pediatric centers during a 10-year period. The following features were analyzed: age at the moment of presentation, symptoms, diagnostic studies, surgical approach, pathological findings, and, in particular, serum tumor markers.
