The aim of this paper was to evaluate the effect of using artificial dermis matrix plus autologous split-thickness skin (ADM and ASTS) in the treatment of deep-burns in hands of severely burned patients?We recruited a total of 58 patients with large area burns greater than 80% that were eschar-excised. Twenty-eight of them were treated with ADM and ASTS (test group); 30 were treated with autologous medium-thickness skin (AMTS) (control group). The healing time of the hand wound was noted, clinical and photographic evaluations were performed, and a Jebsen-Taylor hand function test was compared and analyzed in the two groups. The wound healing time in the test group (24.22?3.34 days) were longer than that of the control group (13.42?3.36 days) and statistically significant. The healing time of skin graft donor sites was shorter than that of the control group (7.14?1.63 vs. 14.28?2.37 days) and statistically significant (P<0.05). The 3rd and 6th month follow-up with clinical and functional evaluations revealed no differences between the two groups. In addition, there was no obvious scar formation and less pigmentation in either group. The repair of deeply burned hands with artificial dermis matrix was beneficial to both wound healing and the donor site, and was beneficial to the whole body rehabilitation of severely burned patients.

Abstract: To date, there are lots of documentations about the adverse effects of smoking on the oral cavity. Albeit, smoking is still considered as a casual thing in our community. Chemicals contained in the cigarette smoke can irritate the gums and soft tissues of the mouth, thus inhibiting wound healing after tooth extraction. This study was aimed to determine the difference in post-extraction dental wound healing between smokers and non-smokers. This was a comparative analytical study with a cross sectional design. Samples were obtained by using total sampling method. Subjects consisted of 16 smokers and 16 non-smokers that fulfilled the study eligibility criteria. Their oral cavities were examined to check the signs of inflammation (calor, dolor, rubor, tumor, and functio laesa). The results showed that there was a difference in post-extraction wound healing in inflammatory phase between smokers and non-smokers. As many as 9.4% of smoker patients and 34.4% of non-smoker patients recovered at 7 days post extraction. The Mann Whitney U test showed a p-value of 0.005. In conclusion, there was a significant difference in post-extraction wound healing between smokers and non-smokers.Keywords: smokers, non-smokers tooth extraction, wound healing Abstrak: Kebiasaan merokok bukan merupakan hal asing di masyarakat walaupun banyak dokumentasi mengenai akibat buruk dari merokok terhadap rongga mulut.

Tooth extraction will always cause injuries. However, the wound healing process can be accelerated under certain conditions. One of the natural ingredients that can accelerate the wound healing process is betadine (Jatropha multifida L.) plant sap. The study was aimed to analyzed the effect of betadine plant sap on wound healing and signs of infection after tooth extraction. Methods: Experimental laboratory study design with post-test only control group design was conducted towards 30 Sprague-Dawley rats. The sampling technique was convenience sampling. The sample was divided into two groups, the treatment group and the control group. The treatment group was administered with betadine plant sap, and the control group was administered with tranexamic acid orally using a gastric probe, then waited 4 hours after. The anaesthesia was then performed using 50 mg/kg body weight of ketamine intramuscularly. The extraction was performed after. Observations was conducted at the clinical criteria on days 1, 3, and 7 and continue to be monitored until the wound heals. Then, the signs of infection were observed. Data analysis was carried out using the Shapiro Wilk normality test. The results showed that the data was not normally distributed. Thus, data analysis was continued using the Mann Whitney statistical test. Results: The results showed a significant difference in the healing of socket wounds after tooth extraction after being administered with betadine sap and tranexamic acid with a value of p=0.037 (p<0.005). Conclusions: Administration of betadine plant sap is proven to be more effective in accelerating the healing process of socket wounds after tooth extraction than tranexamic acid. Keywords: Sprague-Dawley rats; wound healing; pencabutan gigi; getah batang betadine

Tooth extraction is a process of removing teeth from the alveolar bone. In wound healing, fibroblast are very important cells. The main purpose of this study was to determine the effect of mobe leaf 1% and 3% extract gel (Artocarpus lakoocha) on fibroblast proliferation in post extraction tooth socket wound healing. This research used 16 samples of wistar rats, divided into 4 groups, a positive control group, a negative control group and a 1% and 3% mobe leaf extract gel group. The left mandibular incisors were extracted, then 1% and 3% gels of mobe leaf extract were applied on day 1 to day 7. Data analysis was calculated using the Kruskal-Wallis test on clinical data and one way ANOVA test for microscopic. The result of the socket wound healing activity test for a good concentration of mobe leaf extract gel was 3%. This research shows significant resultith p-value of 0.018 (< 0.05) on the closure of the socket wound clinically which means the closure of the wound accelerates because of the mobe leaf 3% extract gel treatment. The distance of fibroblast on microscopically shows significant resultith a p-value of 0.002 (< 0.05), which means that there was an enlargement of the distance fibroblast at the socket wound closure with application of mobe leaf 3% extract gel. From the results of the study it can be concluded that mobe leaf 3% extract gel has the best ability to show acceleration the closure of the socket wound either clinically or microscopically.

Pathological Reaction

Hemostasis and thrombosis in trauma patients consist of physiological hemostasis for wound healing and the pathological reaction of disseminated intravascular coagulation (DIC). Whole body trauma, isolated brain injury, and fat embolism syndrome, if extremely severe, can cause DIC and affect a patient's prognosis. Shock-induced hyperfibrinolysis causes DIC with the fibrinolytic phenotype, contributing to oozing-type severe bleeding. If uncontrolled, this phenotype progresses to thrombotic phenotype at the late stage of trauma, followed by microvascular thrombosis, leading to organ dysfunction. Another type of pathological hemostatic change is acute coagulopathy of trauma shock (ACOTS), which gives rise to activated protein C–mediated systemic hypocoagulation, resulting in bleeding. ACOTS occurs only in trauma associated with shock-induced hypoperfusion and there is nothing to suggest DIC in this phenomenon. This review will provide information about the recent advances in hemostasis and thrombosis in trauma and will clarify the pathogeneses of the pathological processes observed in trauma patients.

Ability To Regenerate

Abstract Background The ability to regenerate is a widely distributed but highly variable trait among metazoans. A variety of modes of regeneration has been described for different organisms; however, many questions regarding the origin and evolution of these strategies remain unanswered. Most species of ctenophore (or “comb jellies”), a clade of marine animals that branch off at the base of the animal tree of life, possess an outstanding capacity to regenerate. However, the cellular and molecular mechanisms underlying this ability are unknown. We have used the ctenophore Mnemiopsis leidyi as a system to study wound healing and adult regeneration and provide some first-time insights of the cellular mechanisms involved in the regeneration of one of the most ancient extant group of multicellular animals. Results We show that cell proliferation is activated at the wound site and is indispensable for whole-body regeneration. Wound healing occurs normally in the absence of cell proliferation forming a scar-less wound epithelium. No blastema-like structure is generated at the cut site, and pulse-chase experiments and surgical intervention show that cells originating in the main regions of cell proliferation (the tentacle bulbs) do not seem to contribute to the formation of new structures after surgical challenge, suggesting a local source of cells during regeneration. While exposure to cell-proliferation blocking treatment inhibits regeneration, the ability to regenerate is recovered when the treatment ends (days after the original cut), suggesting that ctenophore regenerative capabilities are constantly ready to be triggered and they are somehow separable of the wound healing process. Conclusions Ctenophore regeneration takes place through a process of cell proliferation-dependent non-blastemal-like regeneration and is temporally separable of the wound healing process. We propose that undifferentiated cells assume the correct location of missing structures and differentiate in place. The remarkable ability to replace missing tissue, the many favorable experimental features (e.g., optical clarity, high fecundity, rapid regenerative performance, stereotyped cell lineage, sequenced genome), and the early branching phylogenetic position in the animal tree, all point to the emergence of ctenophores as a new model system to study the evolution of animal regeneration.
