Hyperbaric oxygen therapy for pediatric "hypospadias cripple"-evaluating the advantages regarding graft take

Management of penile post-circumcision ischemia by pentoxifylline infusion and hyperbaric oxygen therapy

BACKGROUND

Post-circumcision penile ischemia is a devastating complication. We will present our experience in managing children with various forms of penile ischemia.

MATERIALS AND METHODS

This cohort prospective observational and interventional study was performed on all male children with post-circumcision penile ischemia between April 2017 and October 2021. A designed and approved protocol includes a combination of early pentoxifylline infusion, hyperbaric oxygen inhalation, early catheterization, and appropriate surgical debridement were applied for patients with deep ischemia 11/23, mainly the necrotic skin and subcutaneous tissues. Data of patient age, anesthesia method, monopolar diathermy usage, early presentation and positive wound culture were collected and analyzed statistically.

RESULTS

During the study period 3,382 children were circumcised for non-medical reasons; 23 children were diagnosed with penile ischemia (0.7%), among other complications (9%). Most of the penile ischemia is associated with the use of monopolar diathermy (74%). The use of compressive wound dressing to control post-circumcision bleeding and infections is also responsible for ischemia in 52.2% and 43.5% of the cases. Inexperienced physicians were commonly responsible for ischemia (73.9%). Patients managed at first 24 h had better outcomes than those who were presented later (p = 0.001).

CONCLUSION

In children with post-circumcision penile ischemia, a combination of hyperbaric oxygen therapy and pentoxifylline is especially effective for patients with skin and facial necrosis, this management reduces penile tissue loss.

Role of curcumin in ischemia and reperfusion injury

Ischemia-reperfusion injury (IRI) is an inevitable pathological process after organic transplantations. Although traditional treatments restore the blood supply of ischemic organs, the damage caused by IRI is always ignored. Therefore, the ideal and effective therapeutic strategy to mitigate IRI is warrented. Curcumin is a type of polyphenols, processing such properties as anti-oxidative stress, anti-inflammation and anti-apoptosis. However, although many researches have been confirmed that curcumin can exert great effects on the mitigation of IRI, there are still some controversies about its underlying mechanisms among these researches. Thus, this review is to summarize the protective role of curcumin against IRI as well as the controversies of current researches, so as to clarify its underlying mechanisms clearly and provide clinicians a novel idea of the therapy for IRI.

The utilization of hyperbaric oxygenation therapy in hypospadias repair: a systematic review and meta-analysis

INTRODUCTION

This study aimed to evaluate the efficacy and safety of Hyperbaric Oxygen Therapy (HBOT) use in hypospadias repair through systematic review and meta-analysis of comparative studies.

METHODS

A systematic literature search was performed in May 2021. Comparative studies assessing the surgical outcome of hypospadias repair between control versus HBOT utilization were identified and evaluated according to Cochrane collaboration recommendations. The assessed outcome includes hypospadias repair failures and graft failure for staged repair using a buccal graft. Relative risk with corresponding 95% confidence intervals (CI) were extrapolated. A random-effect model was used to generate pooled effect estimates. Heterogeneity and inter-study variability were assessed using Chi-square and I-square. Subgroup analysis was performed according to primary repair versus redo-hypospadias with buccal graft. PROSPERO registration (CRD42021251423).

RESULTS

Five comparative studies with 576 cases (301 HBOT versus 275 controls) were included. Overall pooled effect estimates showed that the HBOT group has significantly lesser hypospadias repair failure (RR 0.52, 95%CI 0.37, 0.72). Subgroup analysis on the use of HBOT for graft take showed lesser graft failure compared to the control group (RR 0.20, 95% CI 0.05, 0.75), while the use of HBOT for primary and redo single staged hypospadias repair showed lesser complication rate (RR 0.56, 95%CI 0.40, 0.78). Based on ROBINS-I assessment, all included comparative studies are determined to be of serious risk of bias mainly due to presence of confounding.

CONCLUSION

The currently available low-quality of evidence suggests that compared to control groups, HBOT as an adjunctive intervention to complicated hypospadias repair was able to reduce surgical outcome failure and graft failure rates.

Hyperbaric Oxygen Therapy for Reconstructive Urology Wounds: A Case Series

INTRODUCTION

Hyperbaric oxygen therapy (HBOT) has been applied to urological wound healing because it reduces inflammation, facilitates angiogenesis through endothelial proliferation, stimulates fibroblast, lymphocyte, and macrophage activity, and exerts bactericidal effects. Thus, we present a case series of reconstructive urology wounds treated adjunctively with HBOT.

CASE REPORT

Here, we present the cases of eight patients with urology wounds who underwent different forms of surgical reconstruction. Three patients received penile shaft silicone fluid injection with repeated infection, successful excision of a siliconoma mass, and defect closure with a full-thickness skin graft. One patient had hypospadias and multiple post-closure fistulae. Two patients had bilateral keystone flaps (post total penectomy, orchidectomy, perineotomy, and penile tumors) closed with a split-thickness skin graft (STSG). Two patients had Fournier's gangrene in their genital area, for which the wound was debrided and then closed with a STSG. All patients received HBOT after surgery with satisfying results.

CONCLUSION

HBOT promotes wound healing and improves graft integration in patients undergoing urological reconstructive surgery.

Hyperbaric oxygen therapy for paediatric patients: an unintended consequence of the COVID-19 pandemic

OBJECTIVE

Hyperbaric oxygen therapy (HBOT) is a useful adjunctive treatment for selected complicated wounds, including severe diabetic lower extremity ulcerations and compromised skin grafts or flaps. The Sars-CoV-2 (COVID-19) pandemic has disrupted healthcare delivery, with its effects extending to delivery of HBOT. During the pandemic, paediatric patients in our geographic region who were referred for HBOT faced challenges as centres temporarily closed or were unprepared to treat younger patients. Our monoplace HBOT centre modified existing practices to allow for treatment of these patients. This study aims to outline the steps necessary to adapting a pre-existing HBOT centre for the safe treatment of paediatric patients.

METHOD

A retrospective review was performed to identify patients 18 years of age or younger referred for HBOT during 2020. Patient characteristics, referral indications and HBOT complications were collected. Changes implemented to the HBOT centre to accommodate the treatment of paediatric patients were documented.

RESULTS

A total of seven paediatric patients were evaluated for HBOT and six were treated. The mean patient age was four years (range: 1-11 years). Referral diagnoses included sudden sensorineural hearing loss, skin flap or graft compromise, and radiation-induced soft tissue necrosis. All patients tolerated HBOT treatment in monoplace chambers without significant complications noted. Enhancements made to our clinical practice to facilitate the safe and effective treatment of paediatric patients included ensuring the availability of acceptable garments for paediatric patients, maintaining uninterrupted patient grounding (in relation to fire safety), and enhancing social support for anxiety reduction.

CONCLUSION

The results of our review show that paediatric patients can be safely treated within the monoplace hyperbaric environment.
