Adenoma is a benign epithelial lesion with malignant potential and can be found at any site of the gastrointestinal tract. Adenoma of the common bile duct is a rare and unusual cause of bile duct obstruction. We report a case of tubulovillous adenoma of the common bile duct at the cystic duct opening. A 1.8X1.2X1 cm sized, round and lobulated mass was noted on abdominal sonogram, CT scan and endoscopic retrograde cholangiogram, and it was confirmed and treated by surgical resection.

PURPOSE: Globular adiponectin (gAd) is a type of adipocytokine, which is mainly produced by adipose tissue. It has been reported that gAd acts as a pro- as well as an anti-inflammatory factor. Interleukin (IL)-6 and IL-8 are pro-inflammatory cytokines. To investigate the role of gAd on periodontal tissues, the expression of adiponectin receptor 1 (AdipoR1) and the effect of gAd on the expression of IL-6 and IL-8 were investigated in periodontal ligament (PDL) and gingival fibroblasts. METHODS: PDL and gingival fibroblasts were cultured from human periodontal tissues. gAd derived from Escherichia coli and murine myeloma cells were used. The expression of AdipoR1 was estimated by reverse transcription-polymerase chain reaction and western blot. The expression of cytokines was measured by enzyme-linked immunosorbent assay. RESULTS: PDL and gingival fibroblasts expressed both mRNA and protein of AdipoR1. gAd derived from E. coli increased the production of IL-6 and IL-8, but polymyxin B, an inhibitor of lipopolysaccharide (LPS), inhibited IL-6 and IL-8 production induced by gAd in both types of cells. gAd derived from murine myeloma cells did not induce IL-6 and IL-8 production in those cells. gAd derived from E. coli contained higher levels of LPS than gAd derived from murine myeloma cells. LPS increased production of IL-6 and IL-8 in PDL and gingival fibroblasts, but pretreatment of cells with gAd derived from murine myeloma cells did not inhibit LPS-induced IL-6 and IL-8 expression. CONCLUSIONS: Our results suggest that PDL and gingival fibroblasts express AdipoR1 and that gAd does not act as a modulator of IL-6 and IL-8 expression in PDL and gingival fibroblasts.

Adalimumab, a recombinant human IgG monoclonal antibody, selectively blocks tumor necrosis factor-alpha (TNF-alpha) and has been successfully used in the treatment of immune-mediated diseases. In particular, its efficacy has been proven in the treatment of rheumatoid arthritis, spondylarthritis, lymphoproliferative diseases and inflammatory bowel disease. Its use has also been studied for the treatment of psoriasis and yet, paradoxically, cases of new onset or exacerbation of psoriasis continue to increase in patients undergoing treatment with anti TNF-alpha agents. A 51-year-old woman had arthritis for a year and was diagnosed with psoriatic arthritis. After she had received adalimumab for psoriatic arthritis five times during one year, erythematous eruptions were found on her entire body. She then stopped adalimumab therapy for two months, although her skin lesions did not resolve. The patient was diagnosed with psoriasis through biopsy and began using cyclosporine, a topical steroid used for treatment of psoriasis.

PURPOSE: The purpose of this study was to preliminarily evaluate the influence of diabetes mellitus (DM) on periodontal tissue without establishment of periodontitis. METHODS: Seven-week-old db/db mice were used for the diabetic experimental group and systematically healthy mice of the same age were used as controls. After 1 week of acclimatization, the animals were sacrificed for hard and soft tissue evaluation. The pattern of bone destruction was evaluated by stereomicroscope evaluation with alizarin red staining and radiographic evaluation by microscopic computerized tomography images. Histological evaluation was performed with hematoxylin and eosin stain for evaluation of soft tissue changes. RESULTS: In both stereomicroscope evaluation and radiograph image analysis, aggressive form of bone destruction was observed in diabetic animals when compared to the systematically healthy controls. In histological evaluation, apical migration of junctional epithelium with slight inflammatory cell infiltration was observed with disarrangement of connective tissue fibers. CONCLUSIONS: Within the limits of this study, diabetic animals presented distortion in periodontal attachment and an aggressive bone loss pattern when compared to the healthy controls, suggesting that DM has an independent effect on periodontal tissue destruction irrespective of the presence or absence of periodontal disease.

Background: Toe ganglion cysts are often symptomatic and recurrent. Communicating lesions between ganglion cysts and the interphalangeal joint (IPJ) or tendon sheath make it difficult to prevent a recurrence. Temporary restriction of the joint and tendon motion can facilitate surgical site healing. This study analyzed the clinical results of temporary pin fixation of the IPJ after toe ganglion cyst excision. Methods: Sixteen patients with symptomatic toe ganglion cysts underwent surgical treatment. Excision alone was initially performed on 10 patients. Six patients underwent temporary pin fixation of the IPJ after ganglion cyst excision. Repeat excision with pin fixation was performed for recurrence in two patients after excision only. Clinical evaluations and postoperative complications were analyzed. Results: Fourteen of 16 toe ganglion cysts were located near the IPJ. Two cysts not adjacent to the joint completely healed after excision alone. Seven of 14 cysts near the joint recurred after initial excision alone and required repeated reoperation. Eight cysts did not recur after excision with pin fixation, including 2 that recurred after excision alone. Conclusions Temporary IPJ pin fixation after excision for ganglion cysts can be effective for preventing the recurrence of ganglion cysts adjacent to toe IPJ.

Delphinidin is a major anthocyanidin compound found in various vegetablesand fruits. It has anti-oxidant, anti-inflammatory, and various other biologicalactivities. In this study we demonstrated the anti-cancer activity of delphinidin,which was related to autophagy, in radiation-exposed non-small cell lung cancer(NSCLC). Radiosensitising effects were assessed in vitro by treating cells with a subcytotoxicdose of delphinidin (5 M) before exposure to -ionising radiation (IR). Wefound that treatment with delphinidin or IR induced NSCLC cell death in vitro; howeverthe combination of delphinidin pre-treatment and IR was more effective thaneither agent alone, yielding a radiation enhancement ratio of 1.54 at the 50% lethaldose. Moreover, combined treatment with delphinidin and IR, enhanced apoptoticcell death, suppressed the mTOR pathway, and activated the JNK/MAPK pathway.Delphinidin inhibited the phosphorylation of PI3K, AKT, and mTOR, and increasedthe expression of autophagy-induced cell death associated-protein in radiation-exposedNSCLC cells. In addition, JNK phosphorylation was upregulated by delphinidinpre-treatment in radiation-exposed NSCLC cells. Collectively, these results show thatdelphinidin acts as a radiation-sensitizing agent through autophagy induction andJNK/MAPK pathway activation, thus enhancing apoptotic cell death in NSCLC cells.

Natural killer (NK) cells are innate immune cells that are crucial for anticancer activity and have been developed as an immune cell therapy for leukemia. However, their limited effectiveness against solid tumors has prompted research into methods to enhance NK cell activity through combination therapies. Health supplements capable of boosting immune surveillance against tumor cells are gaining attention owing to their potential benefits. Resveratrol, a stilbenoid produced by several plants including peanuts and grapes, reportedly exerts anticancer effects and can activate immune cells. The peanut sprout extract cultivated with fermented sawdust medium (PSEFS) is rich in resveratrol, leveraging its health benefits in terms of the dry weight of herbal products, thus maximizing the utilization of resveratrol’s beneficial properties. Our study compared the efficacy of resveratrol and PSEFS and revealed that PSEFS significantly enhanced NK cell activation compared with an equivalent dose of resveratrol. We investigated the ability of PSEFS to potentiate NK cell anticancer activity, focusing on NK cell survival, tumor cell lysis, and NK cell activation in PSEFS-administered mice. Our findings suggest that PSEFS could be a potential NK cell booster for cancer immunotherapy.
