Burn Wounds And Enzymatic Debridement (Ed) - Past, Present, And Future

Excision of necrotic and devitalized tissues of deep burns is key for optimal care of burn injuries. However, the modality of early tangential excision followed by skin grafting proposed by Zora Janzekovic five decades ago was not received initially with great enthusiasm. At present, it developed to become the standard of care (SOC) despite the special expertise it necessitates and the general anesthesia it requires in addition to several drawbacks including excessive blood loss, risk of hypothermia, and most important potential excision of normal non-burned tissues. Conservative non-surgical selective enzymatic debridement (ED) at present is becoming more popular as an adjunct or even an alternative approach. A systematic review of PubMed electronic database was conducted to identify all experimental and clinical studies about ED of burn wounds. Additional separate searches were also conducted to identify any reports missed by the initial systematic review. Full texts of 59 reports (42 clinical and 17 experimental studies) were retrieved for analysis. 46 studies (11 experimental and 35 clinical) were about the pineapple extract debriding agent. 23 clinical studies describing promising favorable results with pineapple bromelain-based debridement (BBD) concentrate were published in the last 3 years (2020-2023). Though available evidence is not entirely in favor of replacing the current surgical SOC with BBD, it certainly presents ED as a highly advantageous modality for management of burn wounds. Newly described keratinase and SN514 also are promising new products. They both still await further investigation before being clinically adopted.

Systematic review of the microbiology of osteomyelitis associated with war injuries in the Middle East and North Africa

Osteomyelitis is a serious complication associated with war-related limb injuries requiring complicated treatment regimens and management. Few reports have been published from the Middle-East and North-Africa regions about the microbial aetiology of osteomyelitis caused by war injuries. The aim of this review is to collect published data about the microbiology of osteomyelitis in war-related injuries in the region and to derive targeted treatment regimens to manage these serious and limb-threatening infections. A thorough literature search was done using six search engines for pertinent articles. Articles with a minimum of five cases of osteomyelitis from war wounds, citation of microbial aetiology and mention of the timing of cultures obtained in relation to injury were included. Nine studies that met the eligibility criteria were included, involving 1644 patients and a total of 2332 cultures. Gram-negative bacteria were isolated from 1184 cultures, and Gram-positive bacteria were identified from 1148 cultures. Antibiotic coverage should be tailored for Gram-negative organisms in the early stages and Gram-positives in the chronic phase, respectively, with broader coverage reserved for critically ill patients. There is a dire need for further and larger studies about osteomyelitis from war injuries for targeted treatment.

What is the role of incisional vacuum therapy in challenging spinal wounds? A single centre experience

OBJECTIVE

A surgical approach to the treatment of spinal defects and disorders has become more common because of the medical and technological advancements achieved in the last decade. This rising trend in spinal surgeries is associated with adverse events, most notably wound complications. From its introduction, negative pressure wound therapy (NPWT) has proved to be essential in the management of complex wounds and in speeding up wound recovery. The aim of this study is to investigate the use of incisional NPWT in patients undergoing spinal surgery and its role in the prevention of wound complications.

METHOD

This study is a retrospective medical chart review conducted on patients who underwent spinal surgery and received incisional vacuum therapy as part of their treatment. The apparatus was applied intraoperatively following the spinal surgery for all patients included in this study. All surgical procedures were conducted between September 2019 and May 2020. Data entry and analysis were performed between September and October 2020.

RESULTS

A total of five patients' records were reviewed. In our healthcare centre, three patients developed seroma, one developed haematoma, four required revision surgery and one patient required re-operation. There was no wound dehiscence and none of the wounds became infected. Mean length of hospital stay was 11.2 days (standard deviation (SD): 9.5 days) and mean operation time was 333 minutes (SD: 86.4 minutes).

CONCLUSION

There is a scarcity of data on the role of incisional vacuum therapy in the prevention of wound complications associated with spine surgeries. Our study showed promising results for the use of incisional NPWT in the management of spinal wounds. Further research is required in order to enhance wound care by exploiting this potentially beneficial approach.

Preferences of Lebanese adults for the gender of their surgeons: a cross-sectional study

Background

More females are specializing in surgery in Lebanon, but it is not known if a gender bias exists among Lebanese people in their preference of their surgeons.

Aims

This study investigated the preference of Lebanese men and women for the gender of surgeons and explored reasons for their preferences.

Methods

A convenience sample of 1000 Lebanese adults were asked about their preferences for the gender of surgeons of different specialties (paediatrics, cardiology, neurology, orthopaedics, ophthalmology, ear nose and throat, plastic surgery and obstetrics/gynaecology). The association between the participants' sociodemographic characteristics and gender preference for surgeons was examined in bivariate and multivariable regression analyses. Odds ratios (OR) and 95% confidence intervals (CI) were calculated.

Results

Half of the respondents had no gender preference for their surgeons whatever their speciality. Male surgeons were preferred over females for cardiac (44.2% versus 3.7% respectively), neurological (43.4% versus 4.1%) and orthopaedic procedures (41.9% versus 3.5%) whereas male and female obstetricians/gynaecologists were equally preferred (23.6% and 25.0% respectively). Being male (OR = 0.74, 95% CI: 0.57-0.97) or single (OR = 0.65, 95% CI: 0.44-0.96) decreased the likelihood of choosing a male heart surgeon whereas employment increased that likelihood (OR = 1.37, 95% CI: 1.03-1.83). Perceived competence, reputation and trustworthiness of male surgeons influenced participants' choices whereas the choice of an obstetrician/gynaecologist was related to privacy and comfort.

Conclusions

The preference for female surgeons in Lebanon varies by the type of surgical specialty. Qualitative studies exploring the social determinants of patients' preferences are needed.
