MATERIALS AND METHODS: A retrospective cohort study was performed on patients who underwent single-port surgery for colon cancer from 2010 to 2014 at a single institution. Patients were categorized into the following 3 groups according to age: ≤69 years (n=196), 70 to 79 years (n=143), and ≥80 years (n=86). Short-term and long-term outcomes were assessed among 3 groups...

BACKGROUND/AIMS: A new minimally invasive laparoscopic approach for ectopic pregnancy, the laparo-endoscopic single site surgery (LESS), has recently been introduced. The aim of this study is to compare the surgical outcome of this approach with conventional laparoscopy for ectopic pregnancy. METHOD: A review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement was performed. Electronic databases PubMed, MEDLINE, and Scopus were searched in December 2017 by searching the terms "single port laparoscopy" or "laparoendoscopic single site-surgery" or "single site laparoscopy" or "single-incision laparoscopic surgery" and "ectopic pregnancy...

BACKGROUND AND OBJECTIVES: Single-incision plus one port surgery (SILS + 1) provides the advantages of being minimally invasive and easier to perform than pure single-incision laparoscopic surgery. The aim of this study was to investigate the learning curve (LC) for SILS + 1 for sigmoid colon and upper rectal cancer. METHOD: From November 2012 to May 2014, a series of 85 consecutive patients underwent selective SLIS + 1 for sigmoid colon and upper rectal cancer performed by a single surgeon at Nanfang Hospital...

PURPOSE: Evaluate the efficacy of single-port sleeve gastrectomy (SPSG) and then compare it to a less-invasive sleeve approach (three-port) (3PSG) according to a propensity score (PS) matching analysis. MATERIALS AND METHODS: We analyzed all patients who underwent SG through a three-port or a single-port laparoscopic approach. RESULTS: After 2 years, the follow-up was completed in 84% patients treated with 3PSG and 95% patients of the SPSG group...

Implementing the World Health Organization (WHO) recommendations on home-based management of pneumonia with chest indrawing is challenging in many settings. In Papua New Guinea, 120 children presenting with the WHO definition of pneumonia were screened for danger signs, comorbidities and hypoxaemia using pulse oximetry; 117 were appropriate for home care. We taught mothers about danger signs and when to return, using structured teaching materials and a video. The children were given a single dose of intramuscular benzylpenicillin, then sent home on oral amoxicillin for 5 days, with follow-up at Days 2 and 6...

Light-duty gasoline vehicles have drawn public attention in China due to their significant primary emissions of particulate matter and volatile organic compounds (VOCs). However, little information on secondary aerosol formation from exhaust for Chinese vehicles and fuel conditions is available. In this study, chamber experiments were conducted to quantify the potential of secondary aerosol formation from the exhaust of a port fuel injection gasoline engine. The engine and fuel used are common in the Chinese market, and the fuel satisfies the China V gasoline fuel standard...

Background: Patients' satisfaction is the key parameter to measure the quality of healthcare services. Value added-services (VAS) were introduced to improve the quality of medication deliveries and to reduce the waiting time at outpatient pharmacy. Objective: This study aimed to compare the satisfaction levels of patients receiving VAS and traditional counter service (TCS) for prescription refills in Port Dickson Hospital. Methods: A single-center, cross-sectional study was conducted in the outpatient pharmacy department of Port Dickson Hospital from 1 March to 30 June 2017...

Background and Objectives: Single-port laparoscopic surgery (SPLS) is popular in the gynecological field, because it is less invasive and leaves a smaller scar. However, the postoperative shape of the umbilicus is often distorted due to the intensive procedures performed through the small opening. In this report, we describe a technique for forming a satisfactory umbilicus in SPLS. Methods: From March 2016 through April 2017, 32 patients were treated with SPLS by a single gynecologic surgeon...

This paper demonstrates a methodology to miniaturize THz spectroscopes into a single silicon chip by eliminating traditional solid-state architectural components such as complex tunable THz and optical sources, nonlinear mixing and amplifiers. The proposed method achieves this by extracting incident THz spectral signatures from the surface of an on-chip antenna itself. The information is sensed through the spectrally-sensitive 2D distribution of the impressed current surface under the THz incident field. By converting the antenna from a single-port to a massively multi-port architecture with integrated electronics and deep subwavelength sensing, THz spectral estimation is converted into a linear estimation problem...

Modelling of a triple asymmetrical optical multiple ring resonator (TAOMRR) with a 1×3 input-output waveguide has been carried out in the present paper, and its performance as an optical filter is analyzed. The mathematical modelling of the proposed configuration is carried out in the z domain using a delay line signal processing technique. Free spectral range (FSR), group delay, and dispersion characteristics of the proposed TAOMRR are evaluated from the frequency response plot obtained in MATLAB from all the possible input-output port configurations...

The purpose of this study was to model the metallic port in breast tissue expanders and to improve the accuracy of dose calculations in a commercial photon treatment planning system (TPS). The density of the model was determined by comparing TPS calculations and ion chamber (IC) measurements. The model was further validated and compared with two widely used clinical models by using a simplified anthropomorphic phantom and thermoluminescent dosimeters (TLD) measurements. Dose perturbations and target coverage for a single postmastectomy radiotherapy (PMRT) patient were also evaluated...

RATIONALE: Internal hernia due to postoperative adhesions sometimes causes small bowel obstruction (SBO) and requires emergency surgery. The difficulties in the management of SBO with internal hernia include accurate diagnosis and estimation of its ischemic degree and of the risk of SBO recurrences following the surgical procedure. Laparoscopic surgery is a noninvasive to reduce postoperative adhesions and therefore has been widely used recently. However, surgeons often tend to hesitate in applying laparoscopic surgery for SBO because of some situational disadvantages such as poor operating space or iatrogenic bowel injury...

BACKGROUND: The morbidity of lung cancer has long been the highest in cancer. Stage I, stage II and partly of stage III non-small cell lung cancer (NSCLC) are mainly treated by surgery. Lobectomy and segmentectomy both are common lung resection methods. Video-assisted thoracoscopic surgery (VATS) has been widely used in clinical, and the application of single-portvideo-assisted thoracoscopic surgery (SP VATS) has gradually been recognized and accepted by professors. With increasing degree of eldly in society, eldly patients already have become inceasingly difficulties in the diagnosis and treatment of NSCLC...

Two six-port injector valves and one selector valve commonly used in flow injection analysis are combined with a surface plasmon resonance instrument wherein solutions introduced from the two inlets counter-flow inside the flow cell. The system is rather versatile as the same or different solutions can be rapidly and repeatedly introduced to the two fluidic channels in series or in parallel. Unlike most commercial SPR instruments employing a single injector valve, solutions separately injected from the two injector valves can be readily exchanged (< 1 s) between the two channels...

OBJECTIVE: To compare the efficacy and safety of double-pass pulsed dye laser (DWL) and single-pass PDL (SWL) in treating virgin port wine stain (PWS). BACKGROUND: The increase in the extent of vascular damage attributed to the use of double-pass techniques for PWS remains inconclusive. A prospective, side-by-side comparison with a histological study for virgin PWS is still lacking. MATERIALS AND METHODS: Twenty-one patients (11 flat PWS, 10 hypertrophic PWS) with untreated PWS underwent 3 treatments at 2-month intervals...
