Lung pathology

The series of autopsies reported since the beginning of the pandemic have highlighted several patterns of lung damage, both isolated and combined. The factors influencing the occurrence of these different tissue responses to viral aggression by SARS-CoV-2 have not yet been determined. In asymptomatic patients or patients with respiratory symptoms who were not ventilated, lymphocyte pneumonia associated with type II pneumocyte atypical hyperplasia and a few hyaline membranes or focal lesions of acute fibrinous pneumonia have been observed. In critically ill patients, the most frequent pattern is diffuse alveolar damage with interstitial lymphoid infiltration, type II pneumocyte atypia and, very often, capillary or arteriolar microthromboses and/or endothelitis. The precise description of these lesions, which is becoming more and more consensual, makes it possible to understand the favourable effects of corticosteroid therapy in seriously ill patients and the evolution under ventilation towards fibrosis.Copyright © ERS 2021.

Parietex Mini Male Sling for Stress Urinary Incontinence at the Time of Three Piece Penile Prosthesis: Technique and Outcomes

INTRODUCTION AND OBJECTIVE: Male stress urinary incontinence (SUI) and climacturia are often comorbid with erectile dysfunction (ED) post prostatectomy. While the inflatable penile prosthesis (IPP) is the gold standard surgical option for ED, there are many surgical options for male SUI as well as climacturia including bulking agents, Virtue male sling, AdVance>= male sling, mini Jupette with IPP, and artificial urinary sphincter (AUS). We present our technique and outcomes for mini male sling (MMS) with IPP insertion for mild SUI and climacturia using a hydrophilic monofilament polyester mesh. METHOD(S): After obtaining IRB approval, a retrospective review of all IPPs performed by a single high volume surgeon was performed. Those men who underwent IPP insertion with concomitant MMS were analyzed. The technique of MMS placement involves measurement of an approximately 5x3cm Parietex>= mesh (Covidien, MN) and overlying this ventrally over the bulbar urethra. The Parietex>= mesh includes a hydrophilic absorbable collagen film to minimize tissue reaction and risk of erosion. The lateral edges of the mesh are sutured to the 3- and 9 o'clock positions on the left and right corporal bodies, respectively, using a nonabsorbable, braided suture in an interrupted fashion. Mesh is sutured just proximal to the corporotomy sites. Tightness of mesh was measured using the proximal end of a Debakey forceps, with ease of passage when IPP deflated and inability to pass forceps when IPP inflated indicative of proper sizing. RESULT(S): A total of 63 men underwent IPP with MMS between January 2018 and October 2022. All patients had ED after radical prostatectomy. Average patient age was 67 years old, and average IPP size was 21cm with 1cm rear tip extender (RTE). A total of 59 men had SUI, with average pad per day (PPD) of 1.5. Twenty-five men with SUI had comorbid climacturia, and 4 men had preoperative climacturia without SUI. Average PPD post IPP with MMS was 0.1. Of the 29 men with preoperative climacturia, only one did not have resolution of his symptoms post MMS. There was only one reported complication of acute urinary retention requiring temporary foley catheter placement. Two patients required subsequent AUS insertion for persistent SUI. There were no reported cases of infection or mesh erosion. CONCLUSION(S): The hydrophilic Parietex>= mesh is a safe, easy to use, nonreactive, and effective material for mini male sling insertion at the time of IPP placement for men with ED and mild/moderate SUI or climacturia.
