Abstract Third- and fourth-degree frostbites usually result in loss of skin and tissue requiring amputation, and scarring. The 3- to 6-week waiting period is often necessary to determine the severity of the lesion. This period is also a critical time for the rescue of frostbitten tissue. This patient was a 30-year-old man who developed frostbite of his right index finger. He presented to our hospital 4 hours after injury with loss of sensation on the whole index finger and early signs of necrosis. The patient received a series of comprehensive treatments, including fasciotomy, injection of papaverine hydrochloride, baking lamp irradiation, and negative pressure treatment. At the time of discharge, he had re-epithelialization of the index finger by 21 days after injury. The conclusion of this paper is that the comprehensive treatments combined with negative pressure wound treatment has certain clinical application value for the rescue of deep frostbite tissues.

ABSTRACT The incidence of compartment syndrome of the lumbar paraspinal muscles is exceedingly rare. Approximately 24 hours following a high-intensity kettlebell swing workout, a 33-year-old Sailor presented to the medical department on board a forward deployed Wasp-class amphibious assault ship with increasing discomfort in his middle and lower back, and evidence of rhabdomyolysis. Discomfort quickly turned to unrelenting pain coupled with dorsal paresthesias and rigidity in the paraspinal muscles. He was taken emergently to the operating room, where his paraspinal muscles were released via fasciotomy. As a result of limited resources aboard the deployed ship, a negative pressure wound dressing was fashioned using the supplies available aboard the ship. Following 3 days of the negative pressure wound therapy, muscle bulging decreased substantially, and the skin was closed. After 4 weeks of physical therapy, he returned to full duty.

Abstract Purpose Traditionally, previous wound infection was considered a contraindication to secondary skin closure; however, several case reports describe successful secondary wound closure of wounds “preconditioned” with negative pressure wound therapy (NPWT). Although this has been increasingly applied in daily practice, a systematic analysis of its feasibility has not been published thus far. The aim of this study was to evaluate secondary skin closure in previously infected abdominal wounds following treatment with NPWT. Methods Single-center retrospective analysis of patients with infected abdominal wounds treated with NPWT followed by either secondary skin closure referenced to a group receiving open wound therapy. Endpoints were wound closure rate, wound complications (such as recurrent infection or hernia), and perioperative data (such as duration of NPWT or hospitalization parameters). Results One hundred ninety-eight patients during 2013–2016 received a secondary skin closure after NPWT and were analyzed and referenced to 67 patients in the same period with open wound treatment after NPWT. No significant difference in BMI, chronic immunosuppressive medication, or tobacco use was found between both groups. The mean duration of hospital stay was 30 days with a comparable duration in both patient groups (29 versus 33 days, p = 0.35). Interestingly, only 7.7% of patients after secondary skin closure developed recurrent surgical site infection and in over 80% of patients were discharged with closed wounds requiring only minimal outpatient wound care. Conclusion Surgical skin closure following NPWT of infected abdominal wounds is a good and safe alternative to open wound treatment. It prevents lengthy outpatient wound therapy and is expected to result in a higher quality of life for patients and reduce health care costs.

Objective: Hard-to-heal wounds are a surgical challenge, and diabetic foot ulcers (DFUs) are one of the most common and severe varieties. Previous studies have shown that autologous fat grafting (AFG) and negative pressure wound therapy (NPWT) have the potential to promote wound healing. This case study describes how these two methods together helped in the healing of a serious DFU. Case history: A 65-year-old female patient had a severe DFU on her right foot, with a 30-year history of disease and renal failure. By the time symptoms were evident, regular dressing changes and antibiotic treatment were inadequate. She received surgical debridement, AFG and NPWT. Finally, as the granulation tissue covered the full wound bed, the wound was closed by split-thickness skin grafting. One month later, the DFU was fully healed with no recurrences. Conclusion: The application of AFG or components of adipose tissue to treat hard-to-heal wounds has been researched at both the molecular level and in clinic. In this case, we have proved the curative effect of jointly using AFG and NPWT.

This paper is an extension of our previous work about a modular anthropomorphic robotic hand with soft enhancements focusing on simultaneous pinch grasp and suction-based object manipulations. The base structure is a tendon-driven robotic hand comprising five fingers and a palm. Each finger consists of two rigid links covered with soft enhancements. The soft enhancements are like the skin and tissues of the robotic hand. The tip of the finger is equipped with a suction module which can be actuated by regulating negative pressure to the soft layers. While our previous work dealt with the rationale behind and the structure of the modular design with kinematic analysis, this paper focuses on analyzing two specific capabilities of the gripper—pinch grasp and suction modality. Experiments validate that the proposed gripper together with the soft enhancement layers is capable of performing delicate single finger suction-based manipulation tasks and two-finger pinch grasp tasks.

<p>In pursuing significant infrastructural upgrades to solid waste management systems, how do decision-makers balance social safeguarding with wider system improvements? What are the implications for justice, if the people most affected by the development have been providing unrecognised labour within the waste management system? Adopting an intentionally political lens, this thesis presents an analysis of power and justice within the case study of Tibar’s dumpsite-to-landfill upgrade, in Timor-Leste.   This research was conducted at a critical time while the upgrade was developing. Through a political ecology framework, supported by environmental justice, it emerges that there is a disconnect between stakeholders’ and decision-makers’ intentions versus their ability to act on these intentions. Several systemic barriers exist in waste-pickers’ justice being met. In some instances, these barriers constitute such injustices. This thesis further evidences the claim that the impacts of the growing global waste problem are not evenly distributed throughout society.  Tibar dumpsite is established as a political space where the intersection of waste and labour is dynamic and changing, brought to light by the proposed dumpsite-to-landfill upgrade.</p>

Surgical site infections (SSIs) occur at an average rate of 21.1 per cent after Whipple procedures per NSQIP data. In the setting of adherence to standard National Surgery Quality Improvement Program (NSQIP) Hepatopancreatobiliary recommendations including wound protector use and glove change before closing, this study seeks to evaluate the efficacy of using negative pressure wound treatment (NPWT) over closed incision sites after a Whipple procedure to prevent SSI formation. We retrospectively examined consecutive patients from January 2014 to July 2016 who met criteria of completing Whipple procedures with full primary incision closure performed by a single surgeon at a single institution. Sixty-one patients were included in the study between two cohorts: traditional dressing (TD) (n = 36) and NPWT dressing (n = 25). There was a statistically significant difference (P = 0.01) in SSI formation between the TD cohort (n = 15, SSI rate = 0.41) and the NPWT cohort (n = 3, SSI rate = 0.12). The adjusted odds ratio (OR) of SSI formation was significant for NPWT use [OR = 0.15, P = 0.036] and for hospital length of stay [OR = 1.21, P = 0.024]. Operative length, operative blood loss, units of perioperative blood transfusion, intraoperative gastrojejunal tube placement, preoperative stent placement, and postoperative antibiotic duration did not significantly impact SSI formation (P > 0.05).

The paper describes an installation for the degradative depolymerization of polyolefin materials obtained from wastes, hereinafter also referred to as depolymerization for simplicity. The plant, on an industrial scale, is one of the few operating in Poland. However, it is one of the most modern plants in this industry. Design solutions, construction of particular technological lines, compliance with national and EU regulations and the high level of process safety were described in this paper as well as compared to other plants of this type in Poland. Different solutions were presented in drawings and photos of the plant and in fragmentary technological diagrams. The types of waste and the methods of their processing by the plant were also characterized in accordance with the applicable regulations. The waste throughput is from 2000 to 4000 kg/h, while the efficiency of the depolymerization installation itself is 1500 kg/h. The industrial-scale depolymerization process is carried out in one or two stages: by homogenization (extraction) at a temperature up to 200 °C and depolymerization at temperatures up to 400 °C. The obtained products (energy goods) are sold for further processing. The processes, devices and methods are characterized by novel, innovative solutions, covered by a number of patents, which are also described below. The advantage of the presented technology is the substantial simplification of the process and thereby a considerable reduction in investment costs. Among others, the processes of distillation and rectification (low- and negative-pressure) were abandoned.
