Objectives: To validate usefulness of the three phase bone scan for the diagnosis of osteomyelitis in the diabetic foot with soft tissue inflammation. Materials and Methods: Fourteen diabetic feet with soft tissue inflammation were included in this study. We took the bone biopsy from the site of hot uptake on the three phase bone scan but no abnormal findings on the plain radiographs. We observed whether the bone has evidence of osteomyelitis on the patholgic findings such as inflammatory cell infiltration within bone, dead bone, new bone formation and fibrosis. Results: Thirteen of fourteen cases (92.8%) were compatible with osteomyelitis on the pathologic criteria. Inflammatory cell infiltration within bone was observed in thirteen cases, dead bone in twelve cases. new bone formation in four cases. fibrosis in eight cases. All of the four findings were observed in three cases. Conclusion: In the diabetic foot with soft tissue inflammation, the osteomyelitis should be included in differential diagnosis if the lesion reveals increased uptake on three phase bone scan, even though the lesion does not show any abnormal findings on the plain radiographs.

We report a case of cerebral actinomycosis in a 69-year-old immunocompetent woman. The patient showed a progressive worsened mental status for one week. MRI examination showed an increased size of multiple enhancing nodular lesions associated with mild perilesional edema. We performed an open biopsy for the right frontal enhancing lesion. The intraoperative finding showed a yellowish friable lesion that was not demarcated with normal tissue. Pathologically, an actinomycotic lesion with sulfur granules and inflammatory cells was diagnosed. We report an unusual case of diffuse involvement of cerebral actinomycosis. The presence of the uncapsulated friable lesion that consisted mainly of foamy macrophages and lymphocytes could explain the unusual radiological features.

A case of inflammatory pseudotumor of the entire lung In a 61-ycar-old man is prcscntcd. The respiratory symptoms developed 2 months ago and progressed rapidly and the diagnosis of chronic pneumonia with ateletectasis of the entire lung, destroyed lung by tuberculosis and sepsis hAd to be ruled out The operative finding was different from our expectation. This case suggests that the Inflammatory pseudotumor can manifest as a whole lung-involving ass. Inflammatory pseudotumor is a nonneoplastic reactive pulmonary mass lesion that resembles tumor but shows little or no growth. Thc inflammatory pseudotufor usually present as a solitary round lung mass but in this casts progressed rapidly and destroyed the whole lung, which is rare. The patient was discharged with no problem and with outpatient followup.

Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO₂ LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.

Flavonoids are known as natural anti-inflammatory agents. In this investigation, an anti-inflammatory potential of new topical preparation (SK Ato $Formula^{\circledR}$) containing flavonoid mixtures from Scutellaria baicalensis Georgi roots and Ginkgo biloba L. leaves with an extract of Gentiana scabra Bunge roots was evaluated in an animal model of chronic skin inflammation. Multiple 12-O-tetradecanoylphorbol-13-acetate treatments for 7 consecutive days on ICR mouse ear provoked a chronic type of skin inflammation: dermal edema, epidermal hyperplasia and infiltration of inflammatory cells. When topically applied in this model, this row formulation $(5-20\;{\mu}L/ear/treatment)$ reduced these responses. Furthermore, it inhibited prostaglandin $E_2$ generation (17.1-33.3%) and suppressed the expression of proinflammatory genes, cyclooxygenase-2 and $interleulin-1{\beta}$ in the skin lesion. Although the potency of inhibition was lower than that of prednisolone, all these results suggest that Ato $Formula^{\circledR}$ may be beneficial for treating chronic skin inflammatory disorders such as atopic dermatitis.

Intraoral soft tissue can easily be injured by weak mechanical irritation. Each symptom by irritation is various, but most of patients show chronic inflammatory lesion. The fibroma is the most frequent disease found in intraoral area followed by pyogenic granuloma, epulis fissuratum, palatal papillomatosis, and epulis granulomatosum. The inflammatory hyperplasia by mechnical irritation is easily different from other disease, but this shows similar to several benign and malignant tumors required differential diagnosis. By microscopic feature, the lesions is divided by granulatory stage, mixed stage, and fibrotic tissue stage. The inflammatory hyperplasia is differently treated by each clinical features.: only removal of cause or, and excisional biopsy is/are required. This is the cases report of reactive hyperplasia of intraoral soft tissue by mechanical irritation that suggests various treatments of each cases.

The incidence of pediatric inflammatory bowel disease (IBD) is increasing worldwide, especially in the developing countries. It differs from adult disease in clinical manifestations, especially with regard to genetic predisposition in monogenic IBD. Pediatric disease also have a tendency to show more aggressive inflammation and greater extent of lesion. Newer drugs such as anti-tumor necrosis factor ${\alpha}$ have been known to make a difference in treating pediatric IBD. Recent studies suggested that the patients with high risk factors might have some benefits from earlier use of biologics. To achieve treatment goals such as relieving symptoms, optimizing growth, and improving quality of life while minimizing drug toxicity, more research is needed to develop tools for risk stratification in the use of biologics for pediatric IBD.

Pyogenic granuloma is a overzealous proliferation of a vascular type connective tissue as a result of some minor trauma and is a well circumscribed elevated, pedunculated or sessile benign inflammatory lesion of skin and mucous membrane. The clinical features of pyogenic granuloma are indicative but not specific and nearly all cases of pyogenic granulomas are superficial in nature, and there is little if any mention in the literature of these lesions producing alveolar bone even jaw bone loss. This case is somewhat unique in that the lesion was an obvious histologic pyogenic granuloma; however, it appeared to invade the mandibular bone which resulted in the loss of the adjacent teeth. A 12-year-old boy came to Seoul National University Dental Hospital with chief complaints of left facial swelling. The features obtained were as follows; Plain radiograms showed a large well-circumscribed radiolucent lesion on left mandibular ramus area, which made severe expansion of lingual cortex and displacement of lower left 3rd molar tooth germ. Computed tomograms showed large soft tissue mass involving left masticator space with destruction of left mandibular ramus. Histologically, sections revealed loose edematous stroma with intense infiltration of inflammatory cells and proliferation of vascular channels. Also, there were focal areas of extensive capillary proliferation, bone destruction and peripheral new bone formation.

Florid cemento-osseous dysplasia (FCOD) is a benign, non-neoplastic lesion characterized by multiple sclerosing masses only within jawbones. It is frequently confused with chronic diffuse sclerosing osteomyelitis (CDSO) in previous literatures. In our study, two cases of FCOD were examined to know the characteristics of their calcifying tissues. The first case was non-infected, while the second case was severely infected, displaying the typical features of CDSO in clinico-radiologic findings. The infected FCOD case showed a lot of bacterial colonies in the main lesion with relatively rare inflammatory reaction. The globular cementum-like materials of FCOD showed woven bone pattern and was positive for Alcian blue stain, and also positive for the antibodies of ameloblastin, bone morphogenetic protein (BMP) -2 and -4. On the other hands, in the immunostains of matrix metalloproteinase (MMP) -3, -9, -10, and $TNF-{\alpha}$, macrophage infiltrated in the FCOD lesion was rarely observed. These data suggest that the cementum-like materials of FCOD contain various matrix proteins, and that the cementum-like materials are relevant to the overgrowth of the bacterial colonies by inhibition of the regional inflammatory reactions.

Synurus deltoides was previously found to possess significant anti-inflammatory activity especially against chronic inflammation, and strong analgesic activity in vivo. In this study, new anti-inflammatory formulation containing S. deltoides extract as a major ingredient was prepared and in vivo activity was evaluated. The plausible action mechanism was also investigated. The new formulation (SAG) contains 1 part of S. deltoides extract, 0.9 part of Angelica gigas extract and 0.9 part of glucosamine sulfate (w/w). SAG inhibited dose-dependently edematic response of arachidonic acid (AA)- and 12-O-tetradecanoyl 13-acetate (TPA)-induced ear edema in mice, which is an animal model of acute inflammation. SAG showed 44.1 % inhibition of AA-induced ear edema at an oral dose of 50 mg/kg. In an animal model of chronic inflammation, SAG clearly reduced the edematic response of 7 -day model of multiple treatment of TPA (38.1 % inhibition at 200 mg/kg/day). Furthermore, SAG (50-800 mg/kg/day) as well as S. deltoides extract (285 mg/kg/day) significantly inhibited prostaglandin $E_2$ production from the skin lesion of the animals of 7-day model. These results were well correlated with in vitro finding that SAG as well as S. deltoides extract reduced cyclooxygenase (COX)-1- and COX-2-induced prostanoid production, measured in mouse bone marrow-derived mast cells. Therefore, these results suggest that SAG possesses anti-inflammatory activity in vivo against acute as well as chronic inflammatory animal models at least in part by inhibition of prostaglandin production through COX-1/COX-2 inhibition. And COX inhibition of SAG is possibly contributed by S. deltoides extract among the ingredients. Although the anti-inflammatory potencies of SAG were less than those of currently used anti-inflammatory drugs, this formulation may have beneficial effect on inflammatory disorders as a neutraceutical.
