Ulcerative Colitis Diagnosed through Evaluation of Underlying Diseases in a Pyoderma Gangrenosum Adolescent without Gastrointestinal Symptoms.

Pyoderma gangrenosum (PG) is a rare, non-infectious, neutrophilic dermatosis characterized by painful ulcers with indistinct borders and peripheral erythema. The diagnosis of PG requires the exclusion of other causes of similar appearing skin manifestations, including vasculitis and infections. The pathogenesis of PG is not clear; however, dysregulation of the immune system has been suggested in previous studies. More than half of the PG patients have underlying diseases; the most common being inflammatory bowel disease (IBD). The progression of PG in IBD patients is seen after the onset of IBD, usually during its exacerbation. On the other hand, PG may follow a course independent of the intestinal disease. We present a case of an 18-year-old young male with PG that presented before being diagnosed with ulcerative colitis as an associated condition. He had a painful ulcerative lesion on his right shin with no previous gastrointestinal symptoms. This case suggests that investigating for underlying disorders is essential in PG patients despite the lack of symptoms other than the skin lesions.

Trouble-makers in cytologic interpretation of the uterine cervix.

The development and standardization of cytologic screening of the uterine cervix has dramatically decreased the prevalence of squamous cell carcinoma of the uterine cervix. Advances in the understanding of biology of human papillomavirus have contributed to upgrading the histologic diagnosis of the uterine cervix; however, cytologic screening that should triage those that need further management still poses several difficulties in interpretation. Cytologic features of high grade intraepithelial squamous lesion (HSIL) mimics including atrophy, immature metaplasia, and transitional metaplasia, and glandular lesion masquerades including tubal metaplasia and HSIL with glandular involvement are described with accentuation mainly on the differential points. When the cytologic features lie in a gray zone between the differentials, the most important key to the more accurate interpretation is sticking to the very basics of cytology; screening the background and cellular architecture, and then scrutinizing the nuclear and cytoplasmic details.

Sucrose-induced abiotic stress improves the phytochemical profiles and bioactivities of mung bean sprouts.

This study aimed to examine the impact of sucrose treatment on the growth conditions, dietary nutritional quality, and biological activities of mung bean sprouts. Mung bean seeds were sprouted with solutions containing different sucrose concentrations (10, 20, and 30 g/L). The application of exogenous sucrose significantly decreased the height and fresh weight of mung bean sprouts. However, the sucrose-treated sprouts contained more polyphenols, flavonoids, γ-aminobutyric acid, phytosterols, and vitamins. The antioxidant capacities were also significantly higher in the sucrose-treated sprouts than in the control sprouts. The sprouts treated with 2-3 % sucrose showed markedly improved FFA-induced insulin resistance and alcohol-induced oxidative injury in HepG2 cells. Taken together, the elicitor application of sucrose at 3 % during mung bean sprouting could be an effective strategy to improve the dietary phytochemical composition and provide potential health benefits.
