The Macklin Effect Following Trauma: A Case Report of Concurrent Pneumothorax, Pneumoperitoneum, Pneumomediastinum, and Pneumoretroperitoneum in an Intubated Young Adult.
Cureus
December 2024
Department of Trauma Surgery, King Saud Medical City, Riyadh, SAU.
Article Synopsis
- Pneumomediastinum, often occurring silently post-trauma, complicates diagnoses especially when paired with other conditions like pneumothorax and pneumoperitoneum, largely due to the Macklin effect where air escapes from ruptured alveoli.
- An 18-year-old male involved in a car crash was found with severe pneumothorax and subcutaneous emphysema but showed no signs of significant esophageal or bronchial injury upon further evaluation.
- Despite alarming initial imaging, the patient's treatment was conservative, allowing for a gradual healing process and eventual discharge without complications, illustrating the need for careful assessment in trauma management.
Incidence and outcomes following pulmonary barotrauma in COVID-19 ventilated and non-ventilated patients with acute respiratory failure: A retrospective study.
Lung India
January 2023
Department of Radiology, Kokilaben Dhirubhai Ambani Hospital and Medical Research Institute, Mumbai, India.
Background And Objectives: : Alveolar rupture following increased transalveolar pressure on positive pressure ventilation is associated with pulmonary barotrauma (PB). The spectrum varies from pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, retro-pneumoperitoneum and subcutaneous emphysema. We studied the incidence of PB and their clinical characteristics in patients with coronavirus disease 19 (COVID-19)-associated acute respiratory failure.

Background: Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) for ureteropelvic junction obstruction (UPJO) has gained growing acceptance among pediatric urologists, and is increasingly performed as day-case surgery, involving smaller children and infants. However, retroperitoneal CO insufflation may cause hemodynamic derangements, respiratory changes, and hypercapnia, whose consequences are poorly investigated. We, therefore, decided to prospectively study its effect on regional tissue perfusion and oxygenation in a cohort of pediatric patients undergoing R-RALP, using a dedicated anesthetic protocol and cerebral and renal Near InfraRed Spectroscopy (NIRS).

BMC Urol
December 2021
Department of Urology, Nippon Medical School Hospital, 1-1-5, Sendagi, Bunkyo-ku, Tokyo, 113-8603, Japan.
Background: One of the major concerns of patients with upper tract urothelial carcinoma (UTUC) treated with nephroureterectomy is intravesical recurrence (IVR). The purpose of the present study was to investigate the predictive risk factors for IVR after retroperitoneoscopic nephroureterectomy (RNU) for UTUC.
Methods: Clinicopathological and surgical information were collected from the medical records of 73 patients treated with RNU for non-metastatic UTUC, without a history of or concomitant bladder cancer.
Thoracic radiographic features of fatal paraquat intoxication in eleven dogs.
Vet Q
December 2021
Department of Veterinary Medicine, College of Veterinary Medicine, National Chung Hsing University, Taichung, Taiwan.
Background: Paraquat (1,1-dimethyl-4,4-bipyridinium dichloride) is a toxic herbicide. Accidental ingestion of paraquat in animals and humans causes respiratory failure and death.
Aim: To describe the radiographic features of confirmed paraquat intoxication in a group of dogs and determines whether any identified features can facilitate this diagnosis.
