Cisgender cellular tissue-based products improve wound healing.

Neither the CTP sex effect of female CTP derived from cryopreserved human placental membranes, nor male CTP bioengineered from living human keratinocytes and foreskin fibroblasts has been described. Healing in wounds was examined to establish the CTP sex' s role in both males and females. Cisgender CTP wounds had better closure. Overall, male PC, PC-End, and CC rates over time were better than female rates. Outcomes were affected by access, etiology, and follow-up.

An objective comparative study of non-surgical cleansing techniques and cleanser types in bacterial burden management.

Cleansing is a vital component of effective wound hygiene and biofilm management, often accomplished through vigorous mechanical action or through soaking with moistened gauze. In the present study, a quantitative comparison of the effectiveness of different cleansing techniques and solutions in removing bacteria was conducted on 71 chronic wounds using bacterial fluorescence imaging as a real-time diagnostic for moderate to high bacterial loads. Vigorous gauze cleansing for 30 s proved most effective by reducing bacterial fluorescence by 33.99%, surpassing 10-min soaking in bacterial reduction (13.24%). Among different cleansers, no statistically significant differences in effectiveness were observed, but povidone-iodine showed the strongest trend towards bacterial reduction. Sub-analysis highlighted the superiority of antiseptic cleansers over saline and gentle soap (-33.30% vs. -1.80% bacterial reduction respectively). Five percent acetic acid was also shown to be more effective in removing specific bacterial strains (Pseudomonas aeruginosa). Findings from studies like this contribute to refining wound hygiene guidelines and clinical algorithms for bacterial and biofilm management.

Human Amnion Chorion Membrane Allografts in the Treatment of Chronic Diabetic Foot Ulcers: A Literature Review.

OBJECTIVE: To discuss human amnion chorion (placental) membrane allograft (HACMA) use for the treatment of chronic diabetic foot ulcers (DFUs) and to evaluate the effectiveness, cost, and product waste of this therapy. DATA SOURCES: PubMed, Cochrane, and OVID databases. STUDY SELECTION: Twenty-four articles pertaining to HACMA and DFUs published from 2016 to 2020 were selected. DATA EXTRACTION: The data collected included type of wound care product, study design, study size, baseline size of DFU, cost, product wastage, number of applications, and wound healing outcomes. DATA SYNTHESIS: Human amnion chorion membrane allografts in the treatment of chronic DFUs have led to a reduction in healing time and increased the overall percentage of healing, making them more effective in treating DFUs compared with standard of care. These products are offered in multiple sizes with various shelf lives and methods of storage, making them accessible, easy to use, less wasteful, and lower in cost compared with other commercially available products. Promising evidence demonstrates that HACMAs are beneficial in treating complex, high-grade DFUs with exposed tendon or bone. CONCLUSIONS: Human amnion chorion membrane allografts are effective in treating chronic DFUs with a greater percentage of complete wound closure and a reduction in healing time versus standard of care.

Laparoscopic cholecystectomy: relationship of pathology and operative time.

OBJECTIVE: Controversy exists regarding the use and timing of laparoscopic cholecystectomy in the treatment of both acute and chronic cholecystitis. Acute advocates claim to avoid fibrosis and potential dissection injuries, whereas chronic proponents avoid poor visualization due to edema and possible conversion. This study of both acute and chronic cholecystitis cases examines the relationships between pathology, operative time, and outcome of laparoscopic cholecystectomy. METHODS: A retrospective review of medical records and pathology of acute (n = 9) and chronic (n = 62) laparoscopic cholecystectomy cases, performed by 2 surgeons from 1995 to 1999 was undertaken. Using multiple regression techniques, the relationship between operative time and age, sex, race, presenting symptoms, and degree of pathologic cholecystitis was evaluated. RESULTS: One case of acute gangrenous cholecystitis required conversion. None of the chronic cases required conversion. In single variable analysis, abnormal liver function tests, chronic inflammation, wall thickness, and number of stones were each predictive of longer operative time. However, in the multiple regression, abnormal liver function tests were the only clinical factor that remained a predictor of operative time (16 minutes longer, P = 0.05). Time from presentation to operation had no effect on operative time. Twelve patients had preoperative endoscopic retrograde cholangiopancreatography, and 4 had choledocholithiasis (acute n = 1, chronic n = 3). Two chronic patients required postoperative endoscopy for a cystic duct leak (n = 1) and choledocholithiasis (n = 1). The adjusted average operative time for acute and chronic cases was similar (93 versus 74 minutes, P > 0.05). CONCLUSION: Laparoscopic cholecystectomy can be done safely for both acute and chronic cholecystitis with similar operative times. Abnormal liver function tests are associated with longer operative time. Time lapse between presentation and operation has no effect on operative time or outcome.
