Pulmonary Open, Robotic, and Thoracoscopic Lobectomy (PORTaL) Study: Survival Analysis of 6646 Cases.

Objective: The aim of this study was to analyze overall survival (OS) of robotic-assisted lobectomy (RL), video-assisted thoracoscopic lobectomy (VATS), and open lobectomy (OL) performed by experienced thoracic surgeons across multiple institutions.

Summary Background Data: Surgeons have increasingly adopted RL for resection of early-stage lung cancer. Comparative survival data following these approaches is largely from single-institution case series or administrative data sets.

[Does the micropulse laser have an effect on chronic CSC?].

Introduction: Central serous chorioretinopathy (CSC) is the fourth most common cause of vision loss without an evidence-based treatment recommendation. A positive effect of micropulse laser (MPL) treatment has been described in the literature in recent years. This study aimed to reappraise these results in a patient population with chronic CSC.

Standardizing Robotic Lobectomy: Feasibility and Safety in 128 Consecutive Lobectomies Within a Single Healthcare System.

Objective: Single-surgeon cohorts assessing robotically assisted video-assisted thoracic (RA-VATS) lobectomy have reported good outcomes, but there are little data regarding multiple surgeons applying a standard technique in separate hospitals. The purpose of this study was to show how a standardized robotic technique is both safe and reproducible between surgeons and institutions.

Methods: From July 1, 2012, to October 1, 2013, patients undergoing RA-VATS lobectomy for both benign and malignant disease were identified from a prospectively collected database of two thoracic surgeons from different hospitals within the same healthcare system and retrospectively analyzed.

Robotically Assisted Bilateral Bronchoplasty for Tracheobronchomalacia.

We describe the technique for the first robotically assisted bilateral bronchoplasty for the treatment of tracheobronchomalacia. Since 1954, this disease process has been treated with a right thoracotomy and posterior splinting of the tracheal membrane with mesh to restore the C-shape of the trachea. Traditional video-assisted thoracoscopic surgery has been of limited benefit in these cases owing to technical challenges.

Is bark pH more important than tree species in determining the composition of nitrophytic or acidophytic lichen floras?

To study the pH preference of epiphytic lichens, the bark pH of Fraxinus, Tilia, Quercus and Ulmus trees in an urban environment was measured using a flat surface electrode. The total number of trees was 253. A survey was made of the lichens in a 40 × 40 cm quadrat surrounding the pH measurement point.
