“…A meticulous analysis was conducted of 22 relevant publications evaluating conservative treatment for patients with traumatic PTX. We selected 12 articles [12][13][14][15][16][17][18][19][20][21][22][23] where needle aspiration was also discussed as a conservative treatment option. We summarized all data extracted from these 12 studies in Table 1, which includes the first author, the year of publication, the study reference, patient groups, study type, outcomes, and study weaknesses.…”

Traumatic pneumothorax (PTX) occurs in up to 50% of patients with severe polytrauma and chest injuries. Patients with traumatic PTX with clinical signs of tension physiology and hemodynamic instability are typically treated with an urgent decompressive thoracostomy, tube thoracostomy, or needle decompression. There is recent evidence that non-breathless patients with hemodynamically stable traumatic PTX can be managed conservatively through observation or a percutaneous pigtail catheter. We present here a 52-year-old woman who presented to the emergency department with 55 mm traumatic PTX. Following aspiration of 1500 ml of air, clinical improvement was immediately observed, allowing the patient to be discharged shortly thereafter. In hemodynamically stable patients with posttraumatic PTX, without specific risk factors or oxygen desaturation, observation or simple needle aspiration can be a reasonable approach. We aimed in this article to review the available literature on needle aspiration and conservative treatment of traumatic pneumothorax. A total of 12 studies were selected out of 190 articles on traumatic PTX, where conservative treatment versus chest tube decompression was compared. Our case report demonstrated that even a large PTX in a hemodynamically stable patient without other risk conditions, can be successfully treated conservatively with simple needle aspiration to avoid tube thoracostomy complications.

The objective of this article is to assess polymeric insulators subjected to polluted environments. The case studies were conducted on polymeric insulators installed on 500 kV lines. All analyses were carried out with computer simulations, employing finite element methods to calculate the voltage distribution on the surface of the insulators, and the Rizk model in order to assess the discharge voltage of these components, with deposits of pollution layers. The article also presents a number of problems that occur with polymeric insulators, and which have led to the failure of these units, causing great concern to the electricity sector regarding the system. Important conclusions have been obtained, which contribute to the assessment of these events.
