Wound healing under the effect of iodine cadexomer in rats

PURPOSE: To assess vthe action of iodine cadexomer in the healing process of surgical wounds in rats and if cytotoxicity occurs with the systemic absorption of iodine. METHODS: Thirty six Wistar rats were used and performed 53 wounds with surgical punch of 6 mm diameter on them. Two lesions were made diametrically opposed on groups with distilled water (GAD) and sodium chloride (GCS); on the right lesions were used bandage with distilled water and on the left ones dressing with sodium chloride. In cadexomer iodine (GCI) group, a punch injury was made only on the left side and the dressing was carried out with cadexomer iodine. The groups were divided in two sub-groups according to the day of death (7 and 14). Microscopically was used H&E staining, through which the inflammation could be observed and also the neovascularization. Staining with Masson trichrome studied fibrosis. TSH and free T4 were used for absorption recognition of iodine, and its toxic potential was performed before death with the animal anesthetized. RESULTS: Microscopic analysis showed more marked intensity of inflammation in group GAD, subgroup 14 days. Neovascularization showed be discrete in GCS sub-group 14 days. Fibrosis was more pronounced in the group GCI. Comparing the types of treatment, there was statistical significance between groups GCI and GCS (p<0.013). The TSH and T4, showed no difference between the control group and GCI in relation to the absorption of iodine. In evaluating the GCI and control groups, within each treatment, statistical significance was found between them (p<0.001) when compared the days of observation. CONCLUSION: Cadexomer iodine had beneficial effects in all phases of the healing process without cytotoxicity due iodine absorption.

PURPOSE: To investigate the results of the healing process on surgical wounds in the back of Wistar rats using nanocristaline and ionic silver dressing. METHODS: Sixty rats Wistar were submitted to surgical wounds with punch of 8mm in diameter. In 30 animals (groups PN - nanocristaline and AD - control) two surgical wounds were done diametrically opposite on the upper back side. On the right side was used nanocristaline (PN) silver dressing and on the left side, distilled water dressing (AD). On the other group of 30 rats, only one wound was made with the punch, on the right side, and was used ionic silver dressing. So, the groups were divided into three subgroups, according to the day of death (7th, 14th and 21st day). In each of these days the wounds diameter were measured to evaluate the wound contraction. Microscopic data were analyzed using the H&E staining to verify the inflammatory process and neovascularization. The Masson trichrome staining was used to verify the fibrosis. RESULTS: Macroscopically only the subgroup of 21st day showed statistical significance; between the groups AD and PI inflammatory process appeared in the 7th day subgroup in 90% of the cases. In neovascularization there was statistical significance between the groups PN and AD in the subgroup of 7th day. Fibrosis did not show statistical significance in the studied groups. CONCLUSIONS: In relation to wound contraction, PN and PI groups showed better results than the AD group. In regard to histological analysis, H&E staining showed that there was presence of inflammation in all groups, and at the end, the control group (AD) on 7th day, was superior to PN and PI groups. In relationship to fibrosis, no differences were obtained among groups.

Background and Aims: The importance of sessile serrated lesions (SSLs) in the pathogenesis of colorectal carcinoma has been recently established. These are supposed to cause the so-called “interval cancer”, having a rapidly progressive growth and being difficult to detect and to obtain an endoscopic complete resection. We aimed to establish the most important metabolic risk factors for sessile serrated lesions. Methods: We performed a retrospective case-control study, on a series of 2918 consecutive patients who underwent colonoscopy in Gastroenterology and Endoscopy Unit, County Clinical Emergency Hospital, Târgu-Mureș, Romania between 1 st of January 2015-31 th of December 2017. In order to evaluate the metabolic risk factors for polyps’ development, enrolled participants were stratified in two groups, a study group, 33 patients with SSLs lesions, and a control group, 138 patients with adenomatous polyps, selected by systematic sampling for age and anatomical site. Independent variables investigated were: gender, smoking, alcohol consumption, obesity, arterial hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, nonalcoholic liver disease. Results: For SSLs the most common encountered localization was the right colon in 30.55% of cases. By comparative bivariate analysis between SSLs group and control group, it was observed that hypertension (p=0.03, OR 2.33, 95 %CI 1.03-5.24), obesity (p=0.03, OR 2.61, 95 %CI 1.08-6.30), hyperuricemia (p=0.04, OR 2.72, 95 %CI 1.28-7.55), high cholesterol (p=0.002, OR 3.42; 95 %CI 1.48-7.87), and high triglycerides level (p=0.0006, OR 5.75; 95 %CI 1.92-17.2) were statistically associated with SSLs development. By multivariate analysis hypertension and hypertriglyceridemia retained statistical significance. Conclusions: Our study showed that the highest prevalence of SSLs was in the right colon and hypertension and increased triglycerides levels were associated with the risk of SSLs development. These risk factors are easy to detect in clinical practice and may help identifying groups with high risk for colorectal cancer, where screening is recommended.

Corticosteroid Injections

Background: Corticosteroid injections in or around tendons for the treatment of athletic injuries are a common practice among orthopaedic surgeons and are apparently efficacious in the short term, although controversies persist related to local complications. Purpose: This study evaluated short-term (48 hours) biomechanical, biochemical, and histological alterations after a single injection of betamethasone into the normal tendons of rabbits. Study Design: Controlled laboratory study. Methods: A total of 72 New Zealand White rabbits were randomly divided into 2 groups: the test group—in which 36 animals underwent 1 intratendinous injection of betamethasone (1.4 mg / 0.2 mL) in the right calcaneal tendon; the control group—in which the right calcaneal tendon of 36 animals was injected with saline (placebo control group) and the left calcaneal tendon was left untreated for normal standards (normal control). Forty-eight hours later, animals were euthanized and tendons were harvested. Metalloproteinase (MMP1 and MMP2) and interleukin (IL1 and IL6) expression levels, biomechanical resistance (load × elongation parameters), and histomorphometry (hematoxylin and eosin and picrosirius red stains for collagen fibers, tenocytes, and inflammatory cells) were analyzed in the tendons. Results: The test group had a significant reduction in MMP2 expression as compared with the control groups ( P = .027). Regarding the other parameters, there were no additional significant differences between the groups. Conclusion: A single injection of corticosteroid into normal calcaneal tendons did not trigger acute local morphological, structural, or biomechanical injuries at 48 hours, but it did promote a significant decrease in MMP2 levels. Additional studies are needed with increased duration of follow-up, various doses, and multiple injections and in tendinopathic models. Clinical Relevance: Some previous studies demonstrated early structural changes in tendons after a single corticosteroid injection, which was not corroborated by the present study. Metalloproteinase decrease is usually associated with a reduction in collagen degradation, which would be protective for the healing process. More studies are necessary to confirm the possible beneficial effect of these results in the long term and for tendinopathies.

Partial Thickness Burns

Abstract An ideal dressing should ensure that the wound remains moist with exudates but not macerated. Currently, there is no dressing available to suit all wounds, at all stages of the healing process. Although silver-containing dressings are the gold standard for burn wound care, few high-level trials have been completed comparing the clinical utilities of these dressings. In our study, five different types of wound dressings: carboxymethyl cellulose hydrofiber dressing with ionized silver (CMCH-Ag), polyethylene-polyethylene terephthalate aqua fiber dressing with elementary silver (PPAF-Ag), calcium alginate (CA), calcium + zinc alginate (CZA), and 0.2% nitrofurazone-embedded (NF) gauze dressings were compared in regard to histopathological parameters. Children aged between 0 and 18 years with small or middle-sized partial-thickness burns that affected less than 30% of the total body surface area were included in this study. The study groups (CMCH-Ag, PPAF-Ag, CA, and CZA) and the control group (NF) were randomly attained. Wound healing was evaluated by punch biopsies on the 21st day. The thickness of the stratum corneum and the epithelium, the number of papillae, and the papillary length were calculated and compared. The histological parameters of healing, except the stratum corneum thickness, did not show any statistical significance among the groups (P > .05). The dressings that included silver, calcium, or zinc showed useful and similar effects in noninfective burn wounds when compared with nitrofurazone-only dressings. Thus, it may be concluded that silver-containing wound dressings should not be considered as the gold standard in noninfective partial-thickness burn wounds in children.

PURPOSE: To check the effect of zoledronate in bone remodeling during bone healing. METHODS: Thirty rabbits were divided into two groups of fifteen animals each (control and experimental group respectively). Shaft osteotomy was performed on the cranial portion of the fibula of each animal. In the experimental group, a single dose of 0.04mg/kg of zoledronate was administered. In the control group, the same volume of bi-distilled water was administered. After one, two and four weeks, animals of both groups were killed and histological sections of the fibular metaphyseal area were examined histomorphometrically. The parameters analyzed were tissue volume (TV), fractional trabecular bone volume (BV/TV) and fractional medullary fibrous volume (FbV/TV). RESULTS: Tissue volume increased in the experimental group (237.2mm².10-2) compared to the control (166.62mm².10-2). Trabecular bone volume was significantly larger in the experimental (60.2%) than in the control group (34.8%).The amount of fibrosis volume decreased in the experimental group (22%) compared to the control (49.4%). CONCLUSION: The effect of zoledronate is characterized by accentuated stimulus of bone formation in the metaphyseal area, resulting in a larger amount of trabecular bone volume and little fibrosis volume.

Foram utilizados seis eqüinos adultos sem raça definida (SRD), com o objetivo de estudar os aspectos macroscópicos e histopatológicos da cicatrização de pele por segunda intenção, em feridas provocadas cirurgicamente e tratadas topicamente por fitoterápicos: barbatimão (Stryphnodendron barbatiman), calêndula (Calendula officinalis) e confrey (Symphytum officinale), tendo a solução salina como controle das demais. Foram feitas quatro lesões de cada lado da região lombar, do lado direito destinadas à macroscopia e do lado esquerdo à análise histopatológica. As lesões foram tratadas diariamente, observando-se a evolução de cada ferida quanto à retração centrípeta e aspecto macroscópico, até a cicatrização completa. Finalizado o experimento, a análise estatística não revelou variações significativas no estudo comparativo dos fitoterápicos. As observações macroscópicas, histopatológica e a retração centrípeta do halo da lesão nos 15 primeiros dias permitiram concluir que o barbatimão revelou efeito benéfico no processo de cicatrização, seguido pela calêndula, sendo os resultados do grupo controle superiores ao confrey. Comparison between phytotherapics on equine wound healing Abstract It has been carried out a study on the macroscopic and histopathologic aspects of equine skin healing by second intention in wounds cirurgically performed and topically treated with phytotherapics: barbatiman (Stryphnodendrom barbattiman), calendula (Calendula officinalis) and confrey (Symphytum officinale) and physiological solution as control. Four lesions were performed in each side of the lumbar area: the ones in the right side for macroscopic observations and the ones on the left side for histopathologic analysis. The lesions were daily treated with the above mentioned phytotherapics. Each wounds was observed in regard to its centripetal contraction and macroscopic aspects until the complete healing. In this model, the statistic analysis did not reveal significant variations in regard to the comparative effect of the phytoterapics. Macroscopic observations, histopathologic analysis and wound area centripetal retraction in the first fifteen days displayed a beneficial effect of barbatiman in the healing process, better than the other treatment groups, followed by calendula. The results displayed by the control group showed to be superior when compared with confrey.

PURPOSE: To evaluate the morphological aspects of the behavior of 4 types of latex biomembranes implanted in preperitoneal videolaparoscopic inguinoplasty. METHODS: Sixteen inguinoplasties were performed in 12 dogs: group 1 received an impermeable latex biomembrane in the right inguinal region and a prolene prosthesis, as control, in the contralateral inguinal region; groups 2, 3 and 4 received latex biomembranes respectively containing impermeable polyamide, 1-mm thick porous polyamide and 0.5-mm thick porous polyamide. Macro- and microscopic evaluations of the inguinal region and of the removed implants were made on the 7th, 14th, 21st and 28th days in group 1 and on the 28th postoperative day in the other groups. RESULTS: We observed absence of hematoma, seroma and infection; presence of tortuosities; induction of vascular neoformation, inflammatory reaction and collagen deposition, and full encystment of the latex biomembranes, except that with fine porous polyamide, which was partially incorporated, with the formation of microcysts. No latex biomembrane induced fibrosis as observed in the prolene control group. CONCLUSIONS: The biomembranes maintain induction of the healing process without fibrosis, are fully encysted and, except for the one with fine porous polyamide, are not incorporated into adjacent tissues. The latex biomembrane, with or without polyamide, is not recommended as a separate material for preperitoneal inguinoplasty.

Abstract: Coffee is known as food and drink as well as alternative medicine for various types of wounds. One of the most coffee plants in Indonesia is Robusta coffee (Coffea canephora). This study aimed to determine whether Robusta coffee powder could accelerate the wound healing process. This was an experimental study using four rabbits as subjects. Incisions were made on the rabbit backs, right and left, with a length of 5 cm. Wounds on the left backs, the untreated/control group, were only covered with sterile gauze. Wounds on the right backs, the treated group, were applied with robusta coffee powder and covered with sterile gauze. Robusta coffee powder and gauze were replaced two times a day. Wounds were macroscopically observed for 2 weeks. The results showed that at day 7, the wounds were still equally opened, dry, looked not too deep, and there was a crust on each wound surface. The lengths of the treated wounds were shorter than of the control wounds. At day 14, the edges of the treated wounds looked closer, the crusts were still attached to the wound surfaces and were smaller than of the control wounds. Conclusion: Robusta coffee powder (Coffea canephora) could accelerate the healing process of incised wounds on rabbit skin.Keywords: wound healing, wound incision, robusta coffee powder, coffea canephoraAbstrak: Kopi bukan hanya dikenal sebagai makanan dan minuman saja tetapi bisa juga sebagai obat alternatif dalam menangani berbagai jenis luka.
