Pyoderma gangrenosum is uncommon neutrophilic dermatosis characterized by richness of the mature neutrophilic polynuclear dermal infiltrate. Pyoderma gangrenosum is associated with variable diseases, most commonly inflammatory bowel disease, hematological diseases, malignancies, but it is reported rarely in rheumatoid arthritis. We report a case of pyoderma gangrenosum in rheumoid arthritis patient. A 50-year-old woman admitted to our hospital due to painful pretibial ulcerative skin lesions. She had been treated as rheumatoid arthritis for 8 years. At admission, body temperature was $36.5^{\circ}C$ and other vital sign was unremarkable. Physical examination revealed right pretibial ulceration, multiple pustules on left pretibial area and both palms. Laboratory studies revealed WBC count 7,600/uL (neutrophils 60.3%, eosinophil 3.2%), hemoglobin 11.4 g/dL, platelet count 319,000/uL, ESR 65 mm/hour. Other lab findings were also unremarkable. Skin biopsy was done, which showed dense dermal infiltrate of neutrophils and wound culture were negative. By 8 weeks after systemic high dose corticosteroid (1 mg/kg/day), cyclosporine A (5 mg/kg/day), sulfasalazine 2 g therapy, symptoms and skin ulceration were being improved. Without skin relapse, she is followed up our hospital with low dose corticosteroid and sulfasalazine.

Astaxanthin (ASX) is a xanthophyll pigment isolated from crustaceans and salmonids. Owing to its powerful antioxidant activity, ASX has been reported to have the potential to protect against gastric ulcers and a variety of other illnesses. Histamine (His) is a dietary factor that causes gastric erosion and ulceration in young chicks. In this study, we examined whether ASX had protective effects on dietary histamine-induced lesions in the gizzard and proventriculus of broiler chickens. Four experimental treatment groups were planned: basal diet (BD), BD+His, BD+ASX, and BD+ASX+His, with four chicks (5 days old) in each group and three replications (i.e., a total of 12 chicks per group). The BD was supplemented with either 0.4% His or 100 ppm ASX. The birds were fed ad libitum for 3 weeks, and diets contained no antimicrobial compounds. Supplementing the diet with His significantly decreased body weight gain, but increased the weights of the gizzard and proventriculus of the chicks as compared with those of chicks in the BD group (p<0.05). ASX did not affect His-dependent changes in chick body weight or weights of the gizzard and proventriculus. The loss of gastric glands in the proventriculus, which was observed in His-treated chicks, was not prevented by ASX administration. The frequency of proventricular ulceration, however, was lowered by treatment with ASX, without significant differences between the two supplementation levels. In conclusion, our data showed that ASX might be helpful for alleviating structural damage to the digestive system in poultry under certain stressful conditions.

Background: Cancer stem cells (CSC) are populations of cells responsible for tumor initiation, progression and therapeutic resistance in many cancers. In the present study, we aimed to investigate the expression pattern and clinical significance of two CSC markers, CD133 and Nestin, in a series of skin tumors. Materials and Methods: One hundred and thirteen paraffin blocks from skin cancers including 16 (14%) cases of melanoma, 37 (33%) of squamous cell cancer (SCC) and 60 (53%) of basal cell cancer (BCC) were collected and assembled in a tissue microarray (TMA). The samples were immunohistochemically examined for the expression of CD133 and Nestin. Expression of these markers was also correlated with clinicopathological parameters. Results: A significant difference was observed in the expression of CD133 and Nestin in melanomas, SCC and BCC (p value=0.001). Furthermore, the level of expression was significantly higher in the melanomas compared to the SCC and BCC tumors. Expression of CD133 in the melanoma was significantly associated with increased tumor invasiveness (p value=0.05), a higher rate of metastasis (p value=0.04) and the presence of ulceration (p value=0.02). Increased expression of Nestin was observed in metastatic melanoma (p value=0.04), while no statistically significant correlation was found with other clinicopathological parameters including Breslow thickness, Clark level and ulceration. Conclusions: Elevated expression levels of CD133 and Nestin in the melanomas are associated with advanced disease, with more aggressive and metastatic skin tumors. Therefore, these markers could be potential therapeutic targets for malignant tumors of the skin.

Background: Gastric cancer (GC) is the third most common cancer regarding mortality in the world. The cag pathogenicity island (PAI) of Helicobacter pylori which contains genes associated with a more aggressive phenotype may involve in the pathogenesis of gastrointestinal disease. We here aimed to examine the associations of cagH, cagL, orf17, and cagG genotypes of H. pylori cag PAI with severe gastrointestinal disease. Materials and Methods: A total of 242 H. pylori strains were genotyped. Histopathological examination and classification of subjects were performed. Results: The frequencies of the cagH, cagL, cagG, and orf17 genotypes were 40/54 (74.1%), 53/54 (98.1%), 38/54 (70.4%), and 43/54 (79.6%), respectively, in patients with peptidic ulceration (PU),while in the control group, the frequencies were 87/147 (59.6%) for cagH, 121/146 (82.9%) for cagL, 109/146 (74.7%) for cagG, and 89/146 (61.0%) for orf17. The results of simple logistic regression analysis showed that the cagL and orf17 genotypes were significantly associated with an increased risk of PU not GC; the ORs (95% CI) were 10.950 (1.446-82.935), and 2.504 (1.193-5.253), respectively. No significant association was found between the cagH and cagG genotypes and the risk of both the PU and the GC in Iran (P>0.05). Finally, multiple logistic regression analysis showed that the cagL genotype was independently and significantly associated with the age-and sex-adjusted risk for PU; the OR (95% CI) was 9.557 (1.219-17.185). Conclusions: We conclude that the orf17 and especially cagL genotypes of H. pylori cag PAI could be factors for risk prediction of PU, but not GC in Iran.

Background: Phyllodes tumors of the breast are rare fibroepithelial lesions, so relatively little is known about this disease entity. The present study was designed to identify differences in clinical features between benign borderline and malignant phyllodes tumors. Materials and Methods: Data from 246 women with phyllodes tumors of the breast treated in Cancer Hospital Chinese Academy of Medical Sciences between 2002 and 2012 were collected and analyzed, including age at presentation, age at treatment, course, size of primary tumor, location, histological type, type of surgery and treatment, local recurrence, distant metastasis, fibroadenoma history, disease-free survival and number of mitosis per 10hpf. There are 125 (55%) benign, 55 (24%) borderline and 47 (21%) malignant tumors. Results: In univariate analysis, average age at presentation, average age at treatment, size of primary tumor, ulceration or not, type of primary surgery, distant metastasis and number of mitosis per 10 hpf turned out to be statistically different among the three PT types (p=0.014, 0.018, <0.000, 0.003, <0.000, 0.001 and <0.000, respectively), while recurrence and disease-free survival (DFS) demonstrated trends for statistical significance (P =0.055 and 0.060, respectively). Multivariate analysis revealed distant metastasis and excision were significantly different in benign, borderline and malignant phyllodes tumors of the breast (p=0.041 and 0.018, OR=0.061 and 0.051). At the same time, size of primary tumor with p=0.052 tended to be different between groups (OR=1.127). However, age at treatment, ulceration and DFS showed no statistically significant variation (p=0.400, 0.286 and 0.413, respectively). Conclusions: Benign borderline and malignant phyllode tumors have different distant metastasis risk, different primary tumor size and different surgical procedures, and malignant PTs are more likely to be bigger and to metastasize.

Purpose: Squamous cell carcinoma(SCC) of the lower lip is the most common malignant tumor comprising 90% of all lip SCC. The typical picture of SCC of the lower lip is of an ulcerated lesion with raised margins. Surgery is the treatment of choice for SCC of lower lip. Depending on the location and size of the tumor, different types of flaps are used. We used new method - 'both buccal mucosa transposition flap' for the reconstruction of the near total mucosal defect of the lower lip. Methods: This 67 - year - old men presented with the crusted $1cm{\times}1cm$ sized ulceration of the lower lip that was arised 30 years ago. There were no size and color change, except the bleeding and ulceration. At first, We diagnosed the SCC through the incisinal biopsy. Then We performed the wide excision of the tumor and reconstruction of the lower lip. After the excision of the whole tumor, the defect was measured at $8cm{\times}3.5cm$. We designed the buccal mucosa transposition flap taking care to avoid the parotid duct. The flap was made in a triangular shape for the reconstruction of defected lower lip. The donor site defect can be sutured primarily. Results: A patient in this study had no postoperative complications such as necrosis, dehiscence, infection of the flap or donor site. Reconstructed lower lip is relatively close to that of the natural lip; More satisfactory aesthetic and functional results can be obtained by using this technique rather than other techniques. Conclusion: 'Both buccal mucosa transposition flap' is reliable method for the reconstruction of the large lower lip mucosal defect. The operation is simple and performed in one stage, with no postoperative complications. This technique can offer consistently good functional and esthetic outcomes after reconstruction of lower lip mucosal defect.

Pyoderma gangrenosum associated with ulcerative colitis is an unknown etiology of destructive skin disorder, characterized by progressive painful ulceration. It begins as a erythematous areola or pustule and rapidly progress into a deep ulceration with a discrete and violaceous edge. Early diagnosis followed with non-compressive moist dressing, topical application and systemic immunosuppressants are cornerstone in treating this disease. We report a case of pyoderma gangrenosum exacerbated with incision and drainage in a 15 year old girl with ulcerative colitis. This case emphasizes the importance of early consideration of pyoderma gangrenosum in patient with a background of related systemic disease and minimal traumatized wound care.

The cause and pathogenesis of inflammatory bowel disease remain unknown and no definitetherapy exists until now. The present study was conducted to investigate the anti-inflammatory effectsof a herbal preparation (HemoHIM) in colitis induced by 30 mg of trinitrobenzene sulfonic acid (TNBS)in rats. Sprague-Dawley rats were divided into 5 groups. Each group was treated with 1 mg ofHemoHIM/ml of drinking water, 4 mg of HemoHIM/ml of drinking water, 50 mg of HemoHIM/kgof body weight (i.p. once every other day) or 10 mg/kg of HemoHIMof body weight (i.p. onceevery other day) from the next day. After 2 weeks, rats were sacrificed and morphologic featuresof colons were examined. Ulceration, adhesion, thickening and dilatation were noticed in the colonicmucosa after TNBS instillation. Intraperitoneal injection of HemoHIM (50 and 100 mg/kg of bodyweight) showed the anti-inflammatory effect on adhesion, thickening, dilatation, ulceration, and theinhibition effect on damage score by 72.7% and 90.9%, respectively. Histologically, the colon of TNBS-treated rat showed inflammatory cell infiltration by polymorphonuclear cells, multiple erosive lesionsignificant improvement in these symptoms. The results obtained suggest marked anti-inflamatoryactivity of the HemoHIM at the dose levels examined.
