BACKGROUND: Few studies have investigated the factors affecting aerosol delivery during non-invasive ventilation (NIV). Our aim was to investigate, using a bench-top model, the effect of different ventilator settings and positions of the exhalation port and nebulizer on the amount of albuterol delivered to a lung simulator. METHODS: A lung model simulating spontaneous breathing was connected to a single-limb NIV ventilator, set in bi-level positive airway pressure (BIPAP) with inspiratory/expiratory pressures of 10/5, 15/10, 15/5, and 20/10 cmH2O, or continuous positive airway pressure (CPAP) of 5 and 10 cmH2O...

Ze-Rui Zhao, Rainbow W H Lau, Peter S Y Yu, Randolph H L Wong, Calvin S H Ng
The advancement of imaging technology has recently facilitated single port minimally-invasive thoracic surgery techniques. Cone-beam computed tomography (CBCT) shows promising results in visualizing the target lesion and its surrounding critical anatomy, with an error of less than 2 mm. The integration of CBCT with the operating room (OR) to form the hybrid OR, provides unparalleled real-time imaging of the patient, which can be used with electromagnetic navigation bronchoscopy to confirm successful navigation and increase procedural accuracy particularly for small peripheral pulmonary targets...

BACKGROUND: The analysis of DNA copy number variants (CNV) has increasing impact in the field of genetic diagnostics and research. However, the interpretation of CNV data derived from high resolution array CGH or NGS platforms is complicated by the considerable variability of the human genome. Therefore, tools for multidimensional data analysis and comparison of patient cohorts are needed to assist in the discrimination of clinically relevant CNVs from others. RESULTS: We developed GenomeCAT, a standalone Java application for the analysis and integrative visualization of CNVs...

INTRODUCTION: Single-port laparoscopic surgery (SPLS) has gained popularity due to its cosmetic benefit, and therefore, has been applied to several kinds of benign operations, such as appendectomy and cholecystectomy. The safety and suitability of SPLS for colon cancer has not been widely proved. We aimed at validating the safety, efficacy, and short-term quality of life (QOL) of SPLS compared with conventional laparoscopic surgery (CLS) in patients with colon cancer. MATERIALS AND METHODS: Between June 2010 and April 2011, a total of 62 patients with pathology-proven colon cancer were randomly allocated to two groups: SPLS and CLS...

I Gockel, D Lorenz
Minimally invasive resections are increasingly employed in oncologic surgery for esophageal carcinoma. The new German S3 guideline states that esophagectomy, as well as reconstruction of the esophagus, can be performed minimally invasively or in combination with open techniques (hybrid). However, the current value of different techniques - ranging from complete minimally invasive esophagectomy over hybrid to robotic surgery - remains unregarded.This review provides a critical comparison of these techniques based on current evidence...

Transumbilical laparoscopic assisted appendectomy combines laparoscopic single port dissection with open appendectomy after exteriorization of the appendix through the port site. Compared to the conventional three-port approach, this technique provides an alternative with excellent cosmetic outcome. We developed a safe and effective technique to perform an intracorporeal single port appendectomy, using the same laparoscope employed in the extracorporeal procedure. Retrospective review of 71 consecutively performed intracorporeal single port appendectomies and 30 conventional three-port appendectomies in children 6 to 17 years of age...

A scheme of single-photon multi-port router is put forward by coupling two optomechanical cavities with waveguides. It is shown that the coupled two optomechanical cavities can exhibit photon blockade effect, which is generated from interference of three mode interaction. A single-photon travel along the system is calculated. The results show that the single photon can be controlled in the multi-port system because of the radiation pressure, which should be useful for constructing quantum network.
