BACKGROUND: Laparoscopic liver resection (LLR) appears to be safe and effective as open liver resection (OLR) for hepatocellular carcinoma (HCC). However, studies comparing LLR with ORL in elderly patients are limited. The purpose of this study is to compare the clinical outcomes of LLR versus OLR for HCC in elderly patients. METHODS: A retrospective analysis was made comparing laparoscopic (n = 11) and open (n = 18) liver resections in elderly patients performed at the University of Naples "Federico II" between January 2010 and December 2014...

Optical Fabry-Perot interferometer sensors based on inner air-cavity is featured with compact size, good robustness and high strain sensitivity, especially when an ultra-thin air-cavity is adopted. The typical shape of Fabry-Perot inner air-cavity with reflection mode of operation is elliptic, with minor axis along with and major axis perpendicular to the fiber length. The first reflection surface is diverging whereas the second one is converging. To increase the visibility of the output interference pattern, the length of major axis should be large for a given cavity length...

BACKGROUND: Technological advances, including navigation, have been made to improve safety and accuracy of pedicle screw fixation. We evaluated the accuracy of the virtual screw placement (Stealth projection) compared to actual screw placement (intra-operative O-Arm) and examined for differences based on the distance from the reference frame. METHODS: A retrospective evaluation of prospectively collected data was conducted from January 2013 to September 2013. We evaluated thoracic and lumbosacral pedicle screws placed using intraoperative O-arm and Stealth navigation by obtaining virtual screw projections and intraoperative O-arm images after screw placement...

Aseptic techniques are those practices designed to reduce the risk of surgical site infection (SSI), defined as such, all those that occur within the first 30 days of the procedure. While the patient’s risk of developing an SSI in dermatologic surgery is low since many of the procedures are considered sterile, there are different factors associated with an increased or decreased risk of developing SSI. The characteristics of the surgical wound (such as involving infected or inflamed tissue or when breaks in the aseptic technique occur), patient characteristics (such as age, comorbidities, medication use and smoking) and procedure factors (such as setting, surgical technique, type of procedure, duration and body region involved)...

BACKGROUND: Although the specialty of cardiothoracic surgery has been practiced in Nigeria for many years, open heart surgery (OHS) has only in the last decade become relatively more frequent, mainly through visiting foreign cardiac surgical teams. At this early phase of development it is faced with multiple challenges, especially financing and local skilled manpower for which solutions have to be identified in order to ensure sustainability and future growth. This study is aimed at highlighting these obstacles to growth of cardiothoracic surgery based on our own institutional experience at Lagos State University Teaching Hospital (LASUTH) and the current status of OHS activity in other cardiothoracic centers in Nigeria...

BACKGROUND: The list of complications reported after decompressive craniectomy (DC) and cranioplasty is progressively increasing. Nonetheless, the exact incidence of these events is still ill-defined. Problems affecting skin flaps after DC and cranioplasty have never been accurately analyzed in papers and their impact on patients' prognosis is largely underestimated. METHODS: In a 10-year time, we treated by DC 450 patients, 344 of whom underwent cranioplasty, either with autologous bone or artificial implants (hydroxyapatite, polyetheretherketone, titanium, polymethylmethacrylate)...

#17
Raphael Kühnreich, Ulrike Holzgrabe
The use of ortho-phthalaldehyde (OPA) for the derivatization of amino acids (AA) is well known. It enables the separation of the derivatives on common reversed phase columns and improves the sensitivity with fluorescence detection. With the use of a chiral thiol an indirect enantioseparation of chiral amines and AAs is feasible. The major drawback of the OPA-derivatization is the poor stability of the products. Here, a method with an in-needle derivatization procedure is optimized to facilitate a quantitative conversion of the AA with OPA and the chiral thiols N-acetyl-L-cysteine or N-isobutyryl-L-cysteine, followed by a subsequent analysis, eluding the stability issue...

Socioeconomic status (SES) is a fundamental contributor to health, and a key factor underlying racial disparities in disease. However, SES data are rarely included in genetic studies due in part to the difficultly of collecting these data when studies were not originally designed for that purpose. The emergence of large clinic-based biobanks linked to electronic health records (EHRs) provides research access to large patient populations with longitudinal phenotype data captured in structured fields as billing codes, procedure codes, and prescriptions...
