Opis:
While the extant penal code includes the concept of an object as dangerousas a firearm or a knife, it does not define such weapons. In practice, the indication of such items is left to the courts. The aim of the study is to assess the medical and legal consequences of using a shovel or spade when attacking a human being with regard to their similarity to a firearm or knife. The research material consists of judgements of the criminal divisions of common courts concerning situations where injuries were caused by the use of a shovel or a spade. The findings lead to the conclusion that the medical and legal consequences of using a shovel or spade against humans are wide ranging. Their use against a person poses a real risk of causing serious injury, and these items should be treated as being as potentially dangerous as a firearm or knife.

Opis:
The aim of this study was to assess whether modified bacterial cellulose can be used for an artificial auricle skeleton. Introduction: The auricle is a part of the external ear. It consists of skin, cartilage, muscles and adipose tissue. The cartilage gives shape to the structure. There are several indications for reconstruction, such as congenital anomalies, mechanical injuries, and burns, and a range of methods have been proposed for the complete reconstruction of the auricle. Material and methods: A bacterial cellulose membrane, at least 25 mm in thickness, was produced in vitro by Acetobacter xylinum culture. The entire artificial human auricle skeleton was made to scale to allow its implantation into an animal model - Wistar rats. Forty rats were divided into four groups of 10 animals. Each group was assigned a different resection time: 14 days, 30 days, 90 days or 720 days. After each resection, an examination of the artificial skeleton and the tissues surrounding it was conducted. The surgical procedure was based on the Nagata technique. Results: Resection after 14, 30, 90 and 720 days shows the progression of the healing process and integration of the artificial skeleton into the animal body. There are no signs of change in the shape or structure of the skeleton. Discussion: Several surgical techniques and biotechnological methods have been developed over the past few years to improve the results of facial reconstruction. Other approaches can be used to create auricle cartilage, based on scaffolds and chondrocytes. Conclusion: My findings indicate that modified bacterial cellulose can be used to form an effective artificial auricle which appears to maintain its shape and elasticity, with no signs of degradation.

Opis:
The aim of the research was to employ radiation to produce flexible carboxymethyl chitosan (CMCS) based hydrogels of uniform structure to characterise their swelling properties and cytocompatibility for potential applications as hydrogel wound dressings. CMCS in aqueous solution was irradiated with an electron beam in the presence of a poly(ethylene glycol) diacrylate (PEGDA) macromonomer as a crosslinker, at 12 different compositions, i.e. 3–20% CMCS, 3 and 5% PEGDA. The obtained hydrogels were subjected to sol–gel analysis. The amount of insoluble fraction (up to 100%) rose with an increase in the PEGDA/polysaccharide ratio. Moreover, the equilibrium degree of swelling, ca. 15 to 200 g of water per g of gel, which was higher for lower content of crosslinker, decreased with the delivered dose, which was associated with an increase in crosslinking density. The in vitro XTT cell viability assay (murine fibroblasts, L929 cell line) showed no significant cytotoxicity of CMCS gels.

Opis:
Accurate diagnosis of acute appendicitis (AA) is still a problem and is not always easy, even for experienced surgeons. Studies have shown that 20 to 30% of the appendices removedwere normal. Therefore, various scoring systems have been developed to aid in the diagnosis of doubtful cases and reduce the number of unnecessary appendectomies. The aim of this study was to assess the diagnostic value of different scoring systems in acute appendicitis. Material and methods. The study involved 94 patients who underwent laparotomy due to suspected acute appendicitis. Medical examination at hospital admission was performed by a resident and a general surgery specialist. The probability of AA was evaluated using six different scoring systems: Alvarado, Fenyo, Eskelinen, Ohman, Tzankis, and RIPASA. The resident calculated the results in individual systems. The decision to perform the operation was taken by a specialist surgeon who did not know the results. Results. Normal appendix was removed in 26% of cases. Eskelinen, RIPASA and Alvarado systems showed highest sensitivity (99%, 88% and 85%, respectively). Tzankis and Fenyo systems showed highest specificity (62% and 50%, respectively). Conclusions. Our study has shown limited value of scoring systems for the diagnosis of acute appendicitis. The systems may improve diagnostic accuracy as they require obtaining a more detailed medical history, and making a more thorough and organized data analysis. However, the scoring systems should be treated only as an aid to diagnosis

Opis:
Introduction: The perforation of gloves during surgical procedures is quite common. A cheap and quite effective method of reducing the risk of blood-borne infections is wearing two pairs of gloves. Unfortunately, some surgeons are reluctant to it, and they report decreased dexterity and sensation. The aim of the study was to evaluate surgeons’ double-gloving practices to determine the factors related to compliance. Material and methods: An anonymous, 21-question survey in Polish was sent by post to 41 surgical departments. The questions concerned: demographic data, type of surgical gloves used, allergy to latex, number of surgeries performed, frequency of using double gloves and negative impressions from using them and finally, the frequency of needlestick injuries during surgical procedures. Results: We received 179 questionnaires back. More than 62% of the surgeons believe that double gloves provide better protection than a single pair, 24% do not believe in this, and 14% have no opinion. Only 0.6% of respondents always use double gloves during surgery, 19% double glove in at least 25% of cases and 68% do it occasionally. 13% of the surgeons declared that they had never worn double gloves. During high-risk procedures, 86% of respondents wear double gloves. About half of respondents (50.3%) report discomfort while wearing double gloves; 45% – decreased dexterity; about 30% complain of numbness and tingling; and 64% – decreased sensation. Conclusion: Due to the high number of surgical glove perforations and relatively high prevalence of needlestick injuries, it is necessary to use methods that reduce the risk of transmission of pathogens. The habit of using a double pair of gloves should be implemented especially among young surgeons starting to train in their specialities. Consequently, the period of initial discomfort will be combined with the acquisition of surgical skills, which will allow for gradual acclimatization.

Opis:
Surgical site infection (SSI) makes patient care more expensive by prolonging antibiotic usage and hospital stay. Negative pressure wound therapy (NPWT) has been recently reported as a preventive strategy to avoid SSI. We present a simple and low-cost vacuum dressing that may improve surgical wound healing and prevent high-risk wounds from complications.
