Umbilical Reconstruction in Children: A Simplified Operative Technique
No full textThe umbilicus has a paramount aesthetical function for the abdomen and when removed due to a surgical procedure, an umbilicoplasty is mandatory: indeed, its absence could contribute to the development of psychological disorders, especially in childhood. Herein, we describe a straightforward technique to obtain a seemingly natural umbilical scar. This technique, easily taught in a general pediatric surgery environment, may be amenable for any kind of umbilical reconstruction
SISTEMA PER IL MONITORAGGIO DEL CARICO AGENTE SU UN IMPIANTO PROTESICO
No full textSystem for monitoring the load acting on a prosthetic implant.
The present invention relates to a system for monitoring the load acting on a prosthetic implant with sensors provided with at least a force sensor.
According to a specific aspect, the invention concerns a system for the monitoring of the load acting on an elongated bar comprised in an apparatus for the treatment of the pathology of pectus excavatum
Metal/polymer composite Nuss bar for minimally invasive bar removal after Pectus Excavatum treatment: FEM simulations
No full textThis study aims at assessing the mechanical behavior of a composite metal/polymer bar to be implanted in the retrosternal position, in order to correct chest wall deformities, such as Pectus Excavatum. A 300-mm-long, 12.7-mm-wide, and 3.5-mm-thick Nuss bar was considered, made of different metals and biodegradable polymers, fixed at its extremities, and with a constant force of 250 N applied on its center. Two different geometries for the metal elements to be embedded in the polymeric matrix were tested: in the former, thin metal sheets and in the latter, cylindrical metal reinforcing rods were considered. Finite element method simulation results are reported, in terms of maximum stress and strain of the bar. Furthermore, the maximum stress values obtained by varying metal sheet thickness or rod diameter (and therefore the volumetric percentage of metal within the matrix) for different material combinations are also shown; optimal configuration for the Pectus Excavatum treatment was finally identified for a composite Nuss bar
Adnexal torsion in children and adolescents: new trends to conservative surgical approach - Our experience and review of the literature,
No full textThe 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 ten years.
We retrospectively reviewed the medical charts of 127 operative ovarian lesions including 30 ovarian torsions (23,6%) treated in two pediatric centres over a 10-year period. Age at presentation, presenting symptoms, diagnostic studies, surgical procedure and pathological findings were analyzed. Mean age was 13.7 years. Conservative surgery has been performed in 46.7% of the cases and laparoscopic approach in 40%. Ovarian torsion occurred in 56.7% on ovaries with functional lesion, in 23.3% on normal adnexa and in 20% on ovaries with benign neoplasm. The article includes a literature review (2000-2010) and a statistical analysis which shows a slow increase in conservative surgery from 28% to 45%. Laparoscopic surgery accounts for 23.5%. Literature review shows 40.5% normal adnexa, 33.2% non-neoplastic lesions, 25.3% benign neoplasms and 1% malignant neoplasms. The surgical treatment of children and adolescents presenting adnexal torsion should be practised as an emergency and it should be more conservative as possible in order to maximize the future reproductive potential
Pain and anxiety management in minimally invasive repair of pectus excavatum
No full textThe Nuss procedure for the correction of Pectus Excavatum (PE) is associated with intense postoperative pain. Our strategy to control early postoperative pain is to combine epidural with intravenous analgesia. Our aim was to analyse our pain control strategy by reviewing all the PE cases treated at our institution. Sixty consecutive patients, aged between 12 and 26 years old, received the PE operation at our institution from January, 2007 to September, 2010. The median age was 16 (12-27) with a male/female ratio of about 7/1. An epidural catheter was employed in all the cases, with 38 patients (63%) requiring additional drugs to control pain, which remained in place for 74 hours (72-96). The pain score was higher in male patients, but lower in those younger than 16 years old. Moreover, patients that consumed benzodiazepines had a significant decrease in cumulative opioid intake (P = 0.0408). Both gender and age had an impact on pain control, while we noticed a synergistic effect between opiates and tranquillizers
APPARATO PER LA CORREZIONE DELLA PATOLOGIA DEL PECTUS EXCAVATUM
No full textApparatus for the correction of the pathology of pectus excavatum
The present invention relates to an elongated bar from the optimized structure of the type comprised in an apparatus for the repair of the pathology of pectus excavatum. The invention concerns also a method for the removal of the bar from the chest of a patient
The role of tumor markers in the surgical approach of ovarian masses in pediatric age: a 10-year study and a literature review.
No full textPURPOSE:
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. Also, a literature review and statistical analysis (χ(2) test) concerning the increase of different tumor markers in benign and malignant ovarian lesions were related to the study.
RESULTS:
A total of 120 children with 127 ovarian masses (7 with bilateral pathologies) were reviewed. Pathology showed 61 nonneoplastic lesions (48%), 54 benign tumors (42.5%), 5 malignant tumors (4%), and 7 torsed normal ovaries (5.5%). The evaluation of serum tumor markers was performed in 106 cases and was positive in 16 (15.1%): in all of the 5 cases (100%) of malignant neoplastic lesions and in 11 (20.4%) benign neoplastic ones. The literature review confirmed these data, and statistical analysis highlighted them as significant values.
CONCLUSIONS:
The role of tumor markers is still controversial. This is the reason why, before considering a radical treatment, we suggest caution to optimize future fertility.
