Burn and traumatic limb injuries with exposed bone or tendon generally require surgical flaps or amputations for healing. The purpose of this study was to determine if dehydrated human amnion/ chorion membrane allografts (dHACM) with decellularized human collagen matrix (dHCM) could be used to salvage injured human extremities. <strong>Methods and Materials:</strong> dHACM/dHCM was topically applied to the wounds after debridement. Negative Pressure Wound Therapy (NPWT) was concurrently initiated, primarily to bolster the tissue with moisture and contamination control. Approximately every seven days, wounds were re-evaluated for granulation tissue growth response. As needed, patients received dHACM/ dHCM and NPWT in the outpatient or home care settings after discharge. <strong>Results:</strong> Fifteen males and two females (26 extremities) were treated for fourteen burn and three Necrotizing Soft Tissue Infections (NSTI) injuries. Closure was observed in patients after two to five dHACM/dHCM applications. The dHACM/dHCM treatment was initiated: (median) 17-days after injury;NPWT for 17-days;autograft or primary closure after 21-days;discharge 25-days after the first application. <strong>Conclusion:</strong> Treatment with human placental-derived allografts provided a protective covering that enabled the healing cascade to generate granulation tissue formation in extremity wounds with exposed tendon and/or bone. In select limb salvage cases, dHACM/dHCM treatment may be a promising alternative to amputations, tissue rearrangements, free tissue flaps or other techniques for resolution of extremity wounds with bone and tendon exposure.展开更多

Combined debridement is a new technique to deal with the complex chronic wounds. This review introduces several topical methods of combined debridement according to the various color classifications. Methods include combined sharp and hydrogel debridement, combined ultrasonic and enzymatic debridement, ultrasonic debridement combined with surgical debridement and vacuum aspiration on debridement, and other types of debridement. This article also explores why each combined debridement mentioned above can achieve a good effect.展开更多

The m...Fournier’s Gangrene is a formidable rare disease characterized by high mortality rates despite optimal medical and surgical management. It is an acute surgical emergency and requires a high degree of suspicion. The mainstay of treatment is swift open drainage and early aggressive surgical debridement of all necrotic tissue, followed by targeted antibiotic therapy. The authors report on two patients who were admitted to the surgical ward. Both presented with initial perianal sepsis complicated by painful swollen scrotum with rapid progression of gangrene of the scrotal skin and subcutaneous tissue, extensive cellulitis of the perineum, and in one patient crepitation of the anterior abdominal wall. A diagnosis of Fournier’s Gangrene was made and they were both managed by prompt resuscitation, broad-spectrum antibiotics, extensive debridement of all necrotic tissue in theatre, daily wound dressing, and repeated neurectomy on the ward. One of the patients had a colostomy done and the other a cystostomy to divert feces and relieve chronic urinary retention respectively. These patients were successfully treated despite the severity of their conditions which was complicated by severe sepsis in the face of limited diagnostic capabilities and resources, using a multidisciplinary approach and basic clinical monitoring as a guide.展开更多

The objective was to determine and summarize the frequency and characteristics of breast NF and NSTI in the literature. <strong>Methods:</strong> Cases were obtained through PubMed, Google Scholar, Google, and from published article reference sections. One hundred twenty-three cases were gleaned from 96 articles that reported NF and NSTI of the breast (1924 through 2021). <strong>Results:</strong> NF was reported in 70 and NSTI in 53 cases (111 women and 12 men). Patients presented with swollen, painful breasts, erythema, bullae, crepitus, necrosis, gangrene, fever, tachycardia, and neutrophilia. Fifty-nine of 123 (48.4%) patients were septic on admission. The most frequent microorganisms were <em>β</em> hemolytic Group A <em>Streptococcus</em>, and <em>Staphylococcus</em><em> aureus</em>. Treatment consisted of antibiotics, mastectomy and debridement with flaps, skin grafts or primary and secondary closure. Forty-four (63.0%) of the NF cases had chest wall involvement;of these, 18 (14.6%) involved the breast secondarily, <em>P</em> < 0.0001. There were twelve mortalities (9.8%): eleven (9.0%) with NF and one (0.8%) with NSTI,<em> P </em>= 0.007. <strong>Conclusions:</strong> Men and women with breast NF and NSTI presented with similar signs and symptoms and required the same emergent treatment as provided for NF and NSTI of the more common sites. As a time-sensitive disease, patients treated within 12 hours of admission had a better survival. Patients with NF were more likely to have sepsis on admission, a higher mortality, and fascial chest wall/muscle involvement than patients with NSTI.展开更多

Vaccine is live attenuated virus administered to our tissue, to elicit antibody response to the future viral invasion;inhaled virus elicits autoimmunity of varied gradations, [including fatal HLH] in the victim host, secondary to prior abortions/contraception [varied destruction of tissue, germ cells in the victim host];similar significant autoimmunity can be invoked in vaccine administered to tissue.
