Abstract
BACKGROUND Frostbite is becoming increasingly common in urban environments, and severe cases can lead to tissue loss. The treatment goal is to preserve tissue and function; the sooner appropriate treatment is administered, the more tissue can be saved. However, not every patient with deep frostbite seeks medical care promptly. CASE SUMMARY We report the case of a 73-year-old male patient who was lost in the wilderness for 2 d due to trauma and confusion. He experienced deep frostbite on multiple fingers. Treatment should not be discontinued for patients with deep frostbite who present after the optimum treatment timing. Bullae that no longer form (bloody) blisters within 24 h of aspiration should be removed. Mucopolysaccharide polysulfate cream has clinical value in frostbite treatment. The patient was transferred to Chinese Academy of Medical Sciences and Peking Union Medical College Hospital 12 h after being rescued. The patient had contraindications for thrombolysis, the most effective treatment, due to intracranial hemorrhage and presenting past the optimum treatment timing. We devised a comprehensive treatment plan, which involved delayed use vasodilators and high-pressure oxygen therapy at day 49 post-injury. We experimented with mucopolysaccharide polysulfate cream to treat the frostbite. The aim of the treatment was to safeguard as much tissue as possible. In the end, the fingers that suffered from frostbite were able to be partially preserved. CONCLUSION The case indicated that patients with severe frostbite who missed the optimal treatment time and had contraindications for thrombolysis could still partially preserve the affected limbs through comprehensive treatment.

[PMID: 37965279 PMCID: PMC10642355 DOI: 10.2147/ijn.s431061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 10/24/2023] [Indexed: 11/16/2023] Open
Abstract
Carbon dots (CDs), a crucial component of nanomaterials, are zero-dimensional nanomaterials with carbon as the backbone structure and smaller than 10 nm. Due to their beneficial characteristics, they are widely used in biomedical fields such as biosensors, drug delivery, bio-imaging, and interactions with DNA. Interestingly, a novel type of carbon dot, generated by using herbal medicines as synthetic raw materials, has emerged as the most recent incomer in the family of CDs with the extensive growth in the number of materials selected for carbon dots synthesis. Herbal medicine-derived carbon dots (HM-CDs) have been employed in the biomedical industry, and are rapidly emerging as "modern nanomaterials" due to their unique structures and exceptional capabilities. Emerging trends suggest that their specific properties can be used in bleeding disorders, gastrointestinal disorders, inflammation-related diseases, and other common intractable diseases including cancer, menopausal syndrome, central nervous system disorders, and pain of various forms and causes. In addition, HM-CDs have been found to have organ-protective and antioxidant properties, as evidenced by extensive studies. This research provides a more comprehensive understanding of the biomedical applications of HM-CDs for the aforementioned disorders and investigates the intrinsic pharmacological activities and mechanisms of these HM-CDs to further advance their clinical applications.

Abstract
Microwave body tightening and contouring is a common and efficient cosmetic medical procedure. The current study presents preliminary data about microwave treatment for body contouring where an innovative and unexpected benefit on frostbites was shown. This is a case series on two patients with frostbite treated with microwave therapy. The participants received the treatment for five sessions at 20-day intervals, including the beginning of the study. In addition to being satisfied with the treatment of their skin imperfections, the patients noticed a remarkable and progressive improvement in frostbite on their limbs. Both patients experienced a significant improvement in skin sensation and appearance and no side effects were observed. Our findings confirmed the safety and efficacy of microwave therapy in treating cellulite and skin laxity but rather a positively effect and a significant improvement in the treatment of frostbite as a secondary intention.

Abstract
Drug treatment of limb frostbite injuries is complicated due to the poor delivery of medications to affected tissues. External rewarming of the frostbitten area is risky and does not always result in positive outcomes because the dilatation of superficial vessels with constricted deep vessels can lead to irreversible damage, necrosis, and amputation. One of the techniques to restore perfusion of deep vessels in an affected extremity is rewarming with low-power microwave radiation in a specially designed metal chamber. Below are findings following treatment of 14 volunteers with this technique in 2 Tomsk hospitals during winters of 2018-2021. It is demonstrated that timely, i.e. in the early reactive period, application of microwave radiation and appropriate supportive drug treatment results in positive amputation-free outcomes. The key requirement is prompt thermal insulation of the trauma and no prior exposure to external heat sources.

Abstract
Frostbite is an injury that occurs when the skin and tissues are exposed to temperatures below their freezing point. This type of injury can lead to various complications such as functional loss, chronic pain, and psychological trauma. As such, understanding frostbite management is crucial for optimal patient care. A scoping review was conducted in February 2022 using PubMed, EMBASE, referenced articles and snowballing to identify relevant published articled using the terms "frostbite" and "management" and "surgery. Articles related to pathophysiology, classifications, radiography, complications, and medical and surgical management were included to formulate recommendations for practical management. Two hundred fifty-one articles were identified and 54 met inclusion criteria. Rapid rewarming in warm water (40-42 °C) remains the standard of care. Thrombolytic therapy has been shown in numerous studies to improve tissue salvage. Radiographic imaging has become crucial in the evaluation and management in frostbite injury. Current literature recommends delayed surgery with soft tissue debridement and bone scan-guided amputations. Surgical intervention including debridement, selective blister drainage, fasciotomies, surgical salvage, skin grafts' and flaps are often necessary in these patients towards optimizing form and function. The true prevalence and incidence of frostbite injury is unknown. A centralized national database will improve our understanding of the diagnostic and management modalities used in frostbite care. Plastic surgeons have a critical role in the management of frostbite care and must work with an interdisciplinary team to identify the best treatment route for optimal patient care.

Abstract
OBJECTIVE Development of Frostbite healing hydrogel of Manuka honey and hyaluronic acid. SIGNIFICANCE Frostbite is a cold-induced ischemic vascular injury non-responsive to most of the wound healing products. Thrombus-induced ischemia is the main cause of frostbite-related necrosis. Hyaluronic acid is known to possess significant antithrombotic and wound healing activity. Moreover, Manuka Honey is also rich in flavonoids and polyphenols with potential antithrombotic activity. These two agents were together utilized to develop a frostbite healing formulation. METHODS In-silico antithrombotic efficacy of major phytoconstituents of Manuka honey was evaluated using in-silico-docking studies against Tissue plasminogen activator and Cyclooxygenase-1 protein. Further in-vivo frostbite healing evaluation was carried out in Wistar rats, by inducing frostbite with a supercooled rod. RESULTS The results indicate that major leptosin and other major phytoconstituent of Manuka honey has significant antithrombotic property. The hydrogel formulation of HA and MH possess significant antimicrobial efficacy. The wound contraction studies and histopathological evaluation reveals that the hydrogel also has a good frostbite healing activity showing complete wound healing within an 18-day period. The findings of the western blotting studies suggest that the hydrogel acts by VEGF- NRF-2 pathway. CONCLUSION This result implies that the prepared hydrogel can serve as an effective frostbite healing formulation.

Abstract
Since the number of raw material selections for the synthesis of carbon dots (CDs) has grown extensively, herbal medicine as a precursor receives an increasing amount of attention. Compared with other biomass precursors, CDs derived from herbal medicine (HM-CDs) have become the most recent incomer in the family of CDs. In recent ten years, a great many studies have revealed that HM-CDs tend to be good at theranostics without drug loading. However, the relevant development and research results are not systematically reviewed. Herein, the origin and history of HM-CDs are outlined, especially their functional performances in medical diagnosis and treatment. Besides, we sort out the herbal medicine precursors, and analyze the primary synthetic methods and the key characteristics. In terms of the applications of HM-CDs, medical therapeutics, ion and molecular detection, bioimaging, as well as pH sensing are summarized. Finally, we discuss the crucial challenges and future prospects. ![]()

Abstract
Frostbite is tissue damage caused by freezing temperatures and constitutes an important cause of morbidity in cold climate zones and high altitude. The direct effects of sub-zero temperatures lead to tissue freezing, electrolyte shifts and pH alterations, microvascular damage, and eventually to cell death. Upon rewarming, inflammatory reperfusion injury and thrombosis may lead to further tissue damage. Several studies and various case reports show that many patients suffer from long-term sequelae such as vasomotor disturbances (associated with susceptibility to refreezing), and neuropathic and nociceptive pain, as well as damage to skeletal structures. There are still many uncertainties regarding the pathophysiology of these sequelae. It has been shown that the transient receptor potential channel (TRP) family plays a role in cold allodynia. Botulinum Toxin type A (BTX-A) injections have been reported to be beneficial in vasomotor and neuropathic disturbances secondary to frostbite. Epidural sympathetic block has been used for short-term treatment of frostbite induced chronic pain. Furthermore, amitriptyline, gabapentinoids, and duloxetine may have some benefits. Frostbite arthritis clinically resembles regular osteoarthritis. In children there is a risk of epiphyseal cartilage damage leading to bone deformities. Despite some promising therapeutic concepts, the scarcity of data on frostbite long-term sequelae in the literature indicates the need of more in-depth studies of this pathology in all its aspects.

Abstract
In spite of the fact that extremity frostbites are a widespread type of injuries in many countries, specialized equipment for frostbite treatment is lacking. Treatment is carried out by conservative methods. The best results are obtained by using thermal isolation of injured tissues and activation of internal warming. It is proposed to initiate deep warming of frostbitten extremities on exposure to low-power microwave radiation. A microwave chamber has been developed to implement this technique. The efficiency of the approach was earlier demonstrated on animals. An example is given of successful treatment of a cold injury of patient hands and feet that allowed amputation to be avoided.
