The purpose of this study was to present the clinical analysis of the results of lateral arm free flap for small sized and infected diabetic foot ulcer around toes. From May 2006 to December 2007, Seven patients were included in our study. Average age was 52.8 years, six were males and one was female. All had infected diabetic foot ulcer and had exposures of bone or tendon structures. Ulcers were located around great toe in four patients, 4th toe in one and 5th toe in two. Three patients had osteomyelitis of metatarsal or phalanx. After appropriate control of infection by serial wound debridement and intravenous antibiotics, lateral arm flap was applied to cover remained soft tissue defects. Posterior radial collateral artery of lateral arm flap was reanastomosed to dorsalis pedis artery of recipient foot by end to side technique in all cases in order to preserve already compromised artery of diabetic foot. All flaps were designed over lateral epicondyle to get longer pedicle and averaged pedicle length was 8 cm. Two cases were used as a sensate flap to achieve protective sensation of foot. All flaps survived and provided satisfactory coverage of soft tissue defects on diabetc foot ulcers. All patients could achieve full weight-bearing ambulation. No patients has had recurrence of infection, ulceration and further toe amputations. There were three complications, a delayed wound healing of flap with surrounding tissue, a partial peripheral loss of flap and a numbness of forearm below donor site. All patients were satisfied with their clinical results, especially preserving their toes and could return to the previous activity levels. Lateral arm free flap could be recommend for infected diabetic foot ulcers around toes, to preserve toes, coverage of soft tissue defect and control of infection with low donor site morbidity.

Peptic ulcer disease is a gastrointestinal disorder caused by Helicobacter pylori infection and the use of nonsteroid anti-inflammatory drugs. While many studies have been conducted to find the risk factors of peptic ulcers, there are no studies on the suggestion of peptic ulcer prediction models for Koreans. Therefore, the purpose of this study is to implement peptic ulcer prediction model using machine learning based on demographic information, obesity information, blood information, and nutritional information for middle-aged and elderly people. For model building, wrapper-based variable selection method and naive Bayes algorithm were used. The classification accuracy of the female prediction model was the area under the receiver operating characteristics curve (AUC) of 0.712, and males showed an AUC of 0.674, which is lower than that of females. These results can be used for prediction and prevention of peptic ulcers in the middle and elderly people.

Objectives: The purpose of this study was to obtain a natural antibiotic from Phenol-rich compounds; for the dressing and the treatment of chronic wounds. Methods: The Phenol-rich compound sweet gel was prepared by blending four natural herbal extracts, Acacia catechu (L.F.), Momia (Shilajit), Castanea sativa, and Ephedra sinica stapf, with combination of a sweet gel medium, including honey, maple saps, Phoenix dactylifera L. (date), pomegranate extract and Azadirachta indica gum as a stabilizer. The combinations were screened by using a well-diffusion assay with cloxacillin as a control. Pseudomonas spp. was tested with our novel antimicrobial compound. The zones of inhibition in agar culture were measured for each individual component and for the compound, and the results were compared with those of the control group which had been treated with cloxacillin. Data were expressed as means ${\pm}$ standard deviations. Quantitative analyses were performed using the paired t-test. Results: The antibiotic effect of the Phenol-rich compound sweet gel was statistically shown to be more significant than that of cloxacillin against Pseudomonas aeruginosa (P < 0.05). Conclusion: Our novel approach to fighting the antibiotic resistance of Pseudomonas proved to be successful. The Phenol-rich compound sweet gel was found to be suitable for use as an alternative medicine and bioactive dressing material, for the treatment of patients with various types of wounds, including burns, venous leg ulcers, ulcers of various etiologies, leg ulcers on the feet of diabetic, unhealed graft sampling sites, abscesses, boils, surgical wounds, necrotic process, post-operative and neonatal wound infection, and should be considered as an alternative to the usual methods of cure.

Purpose: Diabetic foot ulcer with osteomyelitis is notorious with its complexity and healing difficulties. Bone biopsy is considered to be the gold standard method of guidance for antibiotic therapy. However, it is often replaced by cultures of ulcer swabs or by superficial samples because of the technical difficulties and possible adverse events. In this study, we compared microbiologic results of bone biopsy with those of superficial tissue biopsy or swab culture to investigate concordance and diagnostic value in bone involved diabetic foot ulcers. Methods: This study involved 106 patients with diabetic foot ulcers who showed positive results in bone probing test. Tissue samples for microbiologic tests were collected from all the patients by using superficial cotton swab, superficial tissue biopsy, and bone biopsy. The microbiologic results of bone biopsy were compared with swab culture and superficial tissue biopsy statistically. Results: The positive predictive value of bone probing test for underlying osteomyelitis was 82.1%. Microbiology of the bone biopsy showed same results with those of the swab culture and superficial tissue in 64% and 63%, respectively. Statistical analysis demonstrated that the microbiology of the swab culture or superficial tissue did not coincide with that of the bone biopsy. Conclusion: These results suggest that the microbiologic results of superficial tissue or swab culture do not coincide with those of bony tissue. To select appropriate antibiotic regimen for diabetic ulcer with bone involvement, the specimen for the microbiologic test should be obtained from involved bone.

Purpose: The purpose of this study was to conduct a retrospective investigation on the general characteristics of pressure ulcer and influencing factors of pressure ulcer stage during hospitalization. Methods: A total of 614 patients were selected between January 1, and December 31, 2009 from one acute university hospital if they had pressure ulcers on admission or newly developed pressure ulcer during hospitalization. The data were analyzed using the SPSS WIN 12.0 with percentage, mean, standard deviation, t-test, Chi-square test, ANOVA, and multiple regression analysis. Results: Influencing factors of pressure ulcer stage at discharge were eating (${\beta}=-.068$, p=.047), elimination (${\beta}=-.145$, p<.001), active exercise and movement (${\beta}=-.505$, p<.001), albumin levels (${\beta}=.166$, p<.001), and inflammatory markers (CRP)(${\beta}=-.091$, p=.005). These variables accounted 55.8% of the variance in ulcer stage. Conclusion: Study results indicate that nurses' active role on pressure ulcer care and systematic approach are necessary to manage acutely ill inpatients' pressure ulcers.

Diabetes is a common disease today, and there are also many cases of developing into serious complications called Diabetic Foot Ulcers(DFU). Diagnosis and prevention of DFU in advance is an important task, and this paper proposes the method. Based on existing studies introduced in the paper, it can be seen that foot pressure and temperature information are deeply correlated with DFU. Introduce the process and architecture of SmarTinsole, an IoT device that measures these indicators. Also, the paper describes the preprocessing process for AI-based diagnosis of DFU. Through the comparison of the measured pressure graph and the actual human step distribution, it presents the results that multiple information collected in real-time from SmarTinsole are more efficient and reliable than the previous study.

Background: Aphthous stomatitis is a common disease of the oral mucosa and its pathogenesis is associated with several risk factors. Frequently, minor ulcers are idiopathic in nature and often resolve naturally. However, those ulcers are painful and sensibly compromise patients' eating. There are different treatment strategies for the clinical management of oral aphthae. Methods: The present study assessed the efficacy of a film-forming cream in accelerating the healing and diminishing the pain associated with minor aphthae in a randomized fashion design. The test product (AphtoFix^®) was compared with placebo cream in a cohort of patients with a diagnosis of minor recurrent stomatitis. Patients were randomly distributed into two groups and were followed for 10 days. The primary outcomes included the number of days until symptoms were relieved and the number of days to complete healing. Results: Thirty-six patients completed the follow-up, eighteen per group. All lesions eventually healed within day 10. However, patients in the test group experienced significantly less pain, already from day 1. Patients in the test group also showed a faster healing rate of the lesion with an average of 7 days against the 9 days required for patients in the control group. Conclusion: The present study supported the utility of a film-forming in cream in relieving the patient from symptoms associated with aphthous stomatitis already at day 1 of product use. Patients also displayed faster healing of the lesions when compared to the control group. Further studies with greater sample size and patient stratification according to age and risk factors are recommended to support the present findings.

Plantain has been used for antidiarrhea, antihemorrhage and the remedy of indigestion. Plantain was extracted with ethanol and fractionated systemically with n-hexane, chloroform, ethylacetate (EtOAC) and n-butanol. Antioxidant index (AI was expressed as induction period of oil containing various fractions/induction period of oil of 600 ppm) of EtOAC fraction was the highest among fractions in vitro. The protective effects of the EtOAC fraction of plantain (PE) administered 1 mL orally or intraduodenally on experimentally induced gastritis, gastric ulcer and gastric secretion were evaluated in rats. Sprague-Dawley rats weighing 250∼300 g were divided into 4 groups; negative control group (CON), PE 200 mg/kg treated group (PEL), PE 400 mg/kg treated group (PEH) and positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg treated group-OMT), respectively, PE significantly suppressed HCl-ethanol induced gastric lesions and indomethacin-induced gastric ulcers (administered subcutaneouly) in rats. Specially PE 400 mg/kg showed significantly inhibitory effect, which was more potent than that of 100 mg/kg of commercial drug, cimetidine, and elevated an inhibitory effect to be close to the level in inhibitory ratio of omeprazol administered group in Shay's ucler. On gastric secretion in pylorus ligated rat, PE 200 mg/kg and 400 mg/kg decreased the gastric volume and acid output, but did not show an apparent effect on pepsin activity. In addition, PE 400 mg/kg depressed gastric ulcers induced by water immersion stress and duodenal ulcers induced by cysteamine administered subcutaneouly. These results suggest that the ethylacetate fraction of plantain can be used in prevention and treatment of experimentally induced gastric mucosal damage and ulcers.

A variety of previous pharmacological studies have suggested Liriope platyphylla (L. platyphylla) may exert beneficial biological effects on inflammation, diabetes, neurodegenerative disorder, obesity, constipation, and atopic dermatitis. In addition, hydrocolloid membranes (HCMs) have attracted attention in dermatological care, including in the treatment of scleroderma skin ulcers, cutaneous ulcers, permanent tympanic membrane perforations, pressure sores, and decubitus ulcers in the elderly. To investigate the therapeutic effects of HCM containing an aqueous extract of L. platyphylla (HCM-LP) on second-degree burn wounds, their physico-chemical properties were analyzed and the therapeutic effects were observed in SD rats after treatment with HCM-LP for 14 days. Significant declines in tensile strength (38.4%) and absorptiveness (46.3%), as well as an increase in surface roughness (38.1%) were detected in HCM-LP compared with that of HCM. In SD rats with burned skin, the wound diameter was shorter in the HCM-LP treated group than in the GZ group on post-surgical day 14, while the significant improvements in scar tissue reduction, epithelium regeneration, angiogenesis, and extracellular matrix deposition were observed in the HCM-LP-treated group during all experimental periods. Overall, these results suggest HCM-LP may accelerate the process of healing the burn injury skin of SD rats through the regulation of angiogenesis and connective tissue formation.

The aim of this study was to investigate the effect of crude mucin and saponin from Dioscorea Rhizoma on acute gastric ulcers in rats. The gastric ulcer group (GU group) and mucin-applied group (DR-M group) exhibited serious bleeding of the mucous membrane of the stomach due to the ulcers, as well as blood congestion for three days. The saponin-applied group (DR-S group) exhibited less mucous membrane bleeding, and reddened and inflamed membranes recovered dramatically within 24 hours. After developing an acute pgastric ulcer, the tissues of the stomach, intestine, and liver in the control group and the DR-M group exhibited edema in the submucous membrane, as well as serious bleeding. However, the DR-S group recovered quickly from mucous membrane bleeding due to gastric ulcer. The DR-M group did not show any notable changes in serum formation or activity of antioxidant enzymes compared to the GU rats. Increased AST and ALT activities were detected from the first day with saponin application in the gastric ulcer rats. As the AST and ALT activities decreased, the gastric ulcers recovered with the increased activities of the antioxidant enzymes. Accordingly, this study suggest that mucin in Dioscorea Rhizomahas no effect on the recovery of damaged stomachs due to gastric ulcers, but saponin is mainly responsible for decreasing tissue damage by activating antioxidant enzymes.
