Laparoscopic Partial Nephrectomy for Duplex Kidneys in Infants and Children: How We Do It.

Duplication anomalies of the kidney represent common congenital malformations of the urinary tract. A duplex kidney has often one pole that is poorly or nonfunctioning. In this last case, surgery may be indicated to remove the nonfunctioning pole. The most common indications for partial nephrectomy in pediatrics include symptomatic vesicoureteral reflux to the nonfunctioning pole and/or ectopic ureter or ureterocele causing urinary incontinence. In this article, we describe the technique of laparoscopic partial nephrectomy in infants and children with duplex kidney. A surgical procedure properly executed following critical technical steps is the key factor for the success of surgery.

Technical standardization of ICG near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy for duplex kidney in pediatric patients.

PURPOSE: This study aimed to standardize the operative technique of indocyanine green (ICG) near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy (LPN) and compare it with the standard technique. METHODS: In the last 4 years, we performed 22 LPN (14 right-sided, 8 left-sided) in children with non-functioning moiety of duplex kidney. Patients included 12 girls and 10 boys with a median age of 3.9 years (range 1-10). Patients were grouped according to the use of ICG-NIRF: G1 included 12 patients operated using ICG-NIRF and G2 included 10 patients receiving the standard technique. We standardized the technique of injection of ICG in three different steps. RESULTS: The median operative time was significantly lower in G1 [87 min (range 68-110)] compared with G2 [140 min (range 70-220)] (p = 0.001). One intra-operative complication occurred in G2. At post-operative ultrasound (US), the residual moiety was normal in all patients. An asymptomatic renal cyst related to the site of surgery was visualized at US in 8/22 (36%), with a significantly higher incidence in G2 (6/10, 60%) compared with G1 (2/12, 16.6%) (p = 0.001). Renogram demonstrated no loss of function of residual moiety. No allergic reactions to ICG occurred. CONCLUSION: ICG-NIRF LPN is technically easier, quicker, and safer compared with the standard technique. The main advantages of using ICG-NIRF during LPN are the clear identification of normal ureter, vasculature of non-functioning pole, and demarcation line between the avascular and the perfused pole. The main limitation of ICG technology remains the need for specific laparoscopic equipment that is not always available.

Joint consensus on abdominal robotic surgery and anesthesia from a task force of the SIAARTI and SIC.

Minimally invasive surgical procedures have revolutionized the world of surgery in the past decades. While laparoscopy, the first minimally invasive surgical technique to be developed, is widely used and has been addressed by several guidelines and recommendations, the implementation of robotic-assisted surgery is still hindered by the lack of consensus documents that support healthcare professionals in the management of this novel surgical procedure. Here we summarize the available evidence and provide expert opinion aimed at improving the implementation and resolution of issues derived from robotic abdominal surgery procedures. A joint task force of Italian surgeons, anesthesiologists and clinical epidemiologists reviewed the available evidence on robotic abdominal surgery. Recommendations were graded according to the strength of evidence. Statements and recommendations are provided for general issues regarding robotic abdominal surgery, operating theatre organization, preoperative patient assessment and preparation, intraoperative management, and postoperative procedures and discharge. The consensus document provides evidence-based recommendations and expert statements aimed at improving the implementation and management of robotic abdominal surgery.

Aerodynamic findings and Voice Handicap Index in Parkinson's disease.

OBJECTIVE: To verify possible relations between vocal disability and aerodynamic measures in selected Parkinson's disease (PD) patients with low/moderate-grade dysphonia. METHODS: Fifteen idiopathic dysphonic PD male patients were examined and compared with 15 euphonic subjects. Testing included the following measures: Voice Handicap Index (VHI), maximum phonation time (MPT), mean estimated subglottal pressure (MESGP), mean sound pressure level (MSPL), mean phonatory power (MPP), mean phonatory efficiency (MPE) and mean phonatory resistance (MPR). RESULTS: Statistical analysis showed: a significant reduction in MPR and MSPL in PD subjects compared to the healthy ones; a significant positive correlation between VHI score and MSPL, MPR, MPP, MESGP and a significant negative correlation between VHI and MTP within PD subjects. Test for multiple linear regression showed a significant correlation between VHI score, MPT, MPR and MSPL. CONCLUSIONS: A relationship between VHI and aerodynamic measures was shown in the present study. Compensatory mechanisms may aggravate vocal disability in PD subjects.

Delay in diagnosis affects the clinical outcome in a cohort of cvid patients with marked reduction of iga serum levels.

Common variable immunodeficiency disorders (CVID) represent a collection of diseases leading to an absent or strongly impaired antibody production. CVID presents a wide range of immunological abnormalities and clinical manifestations, including infections, inflammatory and autoimmune diseases, and malignancies. The aim of this observational study was to analyze the epidemiological and clinical features of a cohort of 75 Italian CVID patients, and evaluate the correlation with comorbidity and mortality. Clinical data were retrospectively collected: the cohort was followed-up for a maximum of 30years (mean time of 10.24years, median of 9years). An higher age at the diagnosis of CVID and an higher age at onset of symptoms were significantly associated with a reduction of patients survival if stratified per median of IgA (less than or >8.00mg/dl). Thus IgA levels at diagnosis are correlated with patients survival contributing to identify a subset with a worse prognostic outcome.

Complications after orthognathic surgery: our experience on 423 cases.

INTRODUCTION: Orthognathic surgery is widely used to correct dentofacial discrepancies. However, this procedure presents numerous possible complications. The aim of our study is to review intraoperative and postoperative complications related to orthognathic surgery based upon a 10-year period in the Maxillofacial Surgery Department of Federico II University of Naples. MATERIALS AND METHODS: Medical records of 423 patients who undergone orthognathic surgery in a 10-year period were retrospectively analyzed and complications was noted. Statistical analysis was conduced in order to understand if the type of surgical procedure influenced complications rate. RESULTS: One hundred eighty-five complications in 143 (33.8%) of the 423 treated patients were reported. Complications detected were nerve injury (49 cases, 11.9%), infections (10 cases, 2.4%), complications related to fixation plates or screws (30 cases, 7.1%), bad split osteotomy (8 cases, 1.9%), secondary temporo-mandibular joint disorders (36 cases, 8.5%), dental injuries (21 cases, 5%), condilar resorption (2 cases, 0.5%), and necessity of a second-time surgery (24 cases, 5.7%). CONCLUSIONS: Serious complications seem to be quite rare in orthognathic surgery. Some of the surgical complications found are related to the surgeon experience and not strictly to the risks of the operation itself. Understanding potential complications allows the surgeon to guarantee safe care through early intervention and correctly inform the patient in the preoperative colloquy.

Professional dental and oral surgery liability in Italy: a comparative analysis of the insurance products offered to health workers.

INTRODUCTION: In Italy there has been an increase in claims for damages for alleged medical malpractice. A study was therefore conducted that aimed at assessing the content of the coverage of insurance policy contracts offered to oral health professionals by the insurance market. MATERIAL AND METHODS: The sample analysed composed of 11 insurance policy contracts for professional dental liability offered from 2010 to 2015 by leading insurance companies operating in the Italian market. RESULTS: The insurance products analysed are structured on the "claims made" clause. No policy contract examined covers the damage due to the failure to acquire consent for dental treatment and, in most cases, damage due to unsatisfactory outcomes of treatment of an aesthetic nature and the failure to respect regulatory obligations on privacy. DISCUSSION: On entering into a professional liability insurance policy contract, the dentist should pay particular attention to the period covered by the guarantee, the risks both covered and excluded, as well as the extent of the limit of liability and any possible fixed/percentage excess. CONCLUSIONS: When choosing a professional liability contract, a dentist should examine the risks in relation to the professional activity carried out before signing.

Iatrogenic splenic injury: review of the literature and medico-legal issues.

INTRODUCTION: Iatrogenic splenic injury is a recognized complication in abdominal surgery. The aim of this paper is to understand the medico-legal issues of iatrogenic splenic injuries. We performed a literature review on PubMed and Scopus using iatrogenic splenic or spleen injury and iatrogenic splenic rupture as keywords. Iatrogenic splenic injury cases were identified. Most cases were related to colonoscopy, but we also identified cases related to upper gastrointestinal procedures, colonic surgery, ERCP, left nephrectomy and/or adrenalectomy, percutaneous nephrolithotomy, vascular operations involving the abdominal aorta, gynecological operation, left lung biopsy, chest drain, very rarely spinal surgery and even cardiopulmonary resuscitation. There are several surgical procedures that can lead to a splenic injury. However, from a medico-legal point of view, it is important to assess whether the cause can be attributed to a technical error of the operator rather than being an unpredictable and unpreventable complication. It is important for the medico-legal expert to have great knowledge on iatrogenic splenic injuries because it is important to evaluate every step of the first procedure performed, how a splenic injury is produced, and whether the correct treatment for the splenic injury was administered in a judgment.

Early medical skull surgery for treatment of post-traumatic osteomyelitis 5,000 years ago.

Here we describe the findings of a unique example of the early techniques adopted in neurosurgery around 5000 years ago, consisting in a double well healed skull trephination associated with a post-cranial traumatic event occurring intra vitam to a young male from the Early Chalcolithic cemetery of Pontecagnano (South Italy, ca. 4,900 - 4,500 cal BP). Morphological, X-ray and 3D-CT scan skull-cap evaluation revealed that the main orifice was produced by scraping, obtained by clockwise rotary motion of a right-handed surgeon facing the patient, while the partial trephination was carried out by using a stone point as a drilling tool. In both cases, bone regrowth is indicative of the individual's prolonged postoperative survival and his near-complete recovery. The right femur shows a poorly healed mid-shaft fracture presumably induced by a high energy injury, and a resulting chronic osteomyelitis, affecting both femurs by hematogenous spread of the infection. Our observations on the visual and radiological features of skull and femur lesions, along with evidence on the timing of experimental bone regrowth vs. healing of lower limb fractures associated to long-term bone infections now suggest that this young man underwent a double skull trephination in order to alleviate his extremely painful condition induced by chronic osteomyelitis, which is thought to have been the cause of death.

Confocal laser endomicroscopy in breast surgery: a pilot study.

BACKGROUND: Breast neoplasms include different histopathological entities, varying from benign tumors to highly aggressive cancers. Despite the key role of imaging, traditional histology is still required for a definitive diagnosis. Confocal Laser Endomicroscopy (CLE) is a new technique, which enables to obtain histopathological images in vivo, currently used in the diagnosis of gastrointestinal diseases. This is a single-center pilot feasibility study; the main aim is to describe the basic morphological patterns of Confocal Laser Endomicroscopy in normal breast tissue besides benign and malignant lesions. METHODS: Thirteen female patients (mean age 52.7, range from 22 to 86) who underwent surgical resection for a palpable breast nodule were enrolled. CLE was performed soon after resection with the Cellvizio® Endomicroscopy System (Mauna Kea Technologies, Paris, France), by using a Coloflex UHD-type probe; intravenous fluorescein was used as contrast-enhancing agent. The surgical specimen was cut along the main axis; dynamic images were obtained and recorded using a hand-held probe directly applied both to the internal part of the lesion and to several areas of surrounding normal tissue. Each specimen was then sent for definitive histologic examination. RESULTS: Histopathology revealed a benign lesion in six patients (46%), while a breast cancer was diagnosed in seven women (54%). Confocal laser endomicroscopy showed some peculiar morphological patterns. Normal breast tissue was characterized by a honeycomb appearance with regular, dark, round or hexagonal glandular lobules on a bright stroma background; tubular structures, representing ducts or blood vessels, were also visible in some frames. Benign lesions were characterized by a well-demarcated "slit-like" structure or by lobular structures in abundant bright stroma. Finally, breast cancer was characterized by a complete architectural subversion: ductal carcinoma was characterized by ill-defined structures, with dark borders and irregular ductal shape, formingribbons, tubules or nests; mucinous carcinoma showed smaller cells organized in clusters, floating in an amorphous extracellular matrix. CONCLUSIONS: This is the first pilot study to investigate the potential role of confocal laser imaging as a diagnostic tool in breast diseases. Further studies are required to validate these results and establish the clinical impact of this technique.

Fetal laceration during caesarean section and its medico-legal sequelae.

Fetal laceration is a recognized complication of caesarean delivery. The aim of this study was to investigate the incidence, type, location, risk factors and long-term consequences of accidental fetal incised wounds during caesarean delivery. During a five-year period, we observed 25 cases of fetal lacerations caused by the scalpel during hysterotomy. In 20 of these cases, we observed these lesions as consultants for the Neonatologic Care Unit; the other five cases came under our care after an insurance claim for damages against the gynaecologist. All the infants had a lesion located to the head. In only 5 of the 25 cases the lesion was reported in the operative summary, and only 16 of the 25 mothers had signed an informed consent before surgery. With regard to the 20 cases diagnosed at the Neonatologic Care Unit, the lesion was closed using single stitches in nine cases, and with biological glue in 11 cases. Concerning the five cases that underwent legal proceedings against the gynaecologist, a clinical examination was performed by an expert in Public Health and Social Security in collaboration with a paediatric surgeon to evaluate the degree of biological damage. In all five cases, the result of the legal challenge was monetary compensation for the physical and moral damage caused by the gynaecologists to the patients and their parents. Accidental fetal lesions may occur during caesarean delivery; the incidence is significantly higher during emergency caesarean delivery compared to elective procedures. Patients should sign an informed consent in which they should be informed about the risk of the occurrence of fetal lacerations during caesarean delivery in order to avoid legal complications.
