  • Inflammation is a biological response caused by overactivation of the immune system and is controlled by immune cells via a variety of cytokines. The overproduction of pro-inflammatory cytokines enhances abnormal host immunity, resulting in diseases such as rheumatoid arthritis, cardiovascular disease, Alzheimer's disease, and cancer. Inhibiting the production of pro-inflammatory cytokines such as interleukin (IL)-12p40, IL-6, and tumor necrosis factor $(TNF)-{\alpha}$ might be one way to treat these conditions. Here, we investigated the anti-inflammatory activity of compounds isolated from Cimicifuga dahurica (Turcz.) Maxim., which is traditionally used as an antipyretic and analgesic in Korea. In primary cell culture assays, 12 compounds were found to inhibit the production of pro-inflammatory cytokines (IL-12p40, IL-6, and $TNF-{\alpha}$) in vitro in bone marrow-derived dendritic cells stimulated with LPS.

  • The surgical treatment of advanced carcinomas and some benign tumors having clinically malignant behaviors of the head and neck region often require extensive resection, necessitating large flaps for reconstruction. Since the original upper arm flap was described by Tagliacozzi in 1597, a variety of technique such as random pattern local flap, axial flap, distant flap, scalping flap, myocutaneous flap, free flap etc. have been proposed for reconstruction of head, face and neck defects. Reconstruction of the facial defects usually require the use of distant tissue. Traditionally, nasal reconstruction has been carried out with a variety of forehead flaps. In recent years, there has been more acceptance of immediate repairs following the removal of these tumors. As a result, patients are more willing to undergo these extensive resections to improve their chances of cure, with the reasonable expectation that an immediate reconstruction will provide an adequate cosmetic result. Authors experienced 13 cases of head and neck tumor during last three and half years that required wide excision and immediate reconstruction with various flaps, not with primary closure or simple skin graft. We present our experience with varied flaps for reconstruction after wide resection of head and neck tumors 3 cases of defect of dorsum of nose or medial canthus with island forehead flaps, lower eyelid defect with cheek flap, cheek defect with Limberg flap, orbital floor defect with Temporalis muscle flap, lateral neck defects with Pectoralis major myocutaneous flap or Latissimus dorsi myocutaneous free flap, subtotal nose defect with scalping flap, wide forehead defect with Dorsalis pedis free flap and 3 cases of mandibular defect or mandibular defect combined with lower lip defect were reconstructed with free vascularized iliac bone graft or free vascularized iliac bone graft concomitantly combined with free groin flap pedicled on deep circumflex iliac vessels We obtained satisfactory results coincided wi th goal of treatment of head and neck tumors, MAXIMAL CURE RATE with MINIMAL MORBIDITY, OPTIMAL FUNCTION, and an APPEARANCE as close to normal as possible.

  • Objective : To study the factors relating to operative treatment for spinal metastasis in Thailand during 2005-2014 and to determine the hospital costs, mortality rate, and incidence of perioperative complication. Methods : Inpatient reimbursement data from 2005 to 2014 was reviewed from three national healthcare organizations, including the National Health Security Office, the Social Security Office, and the Comptroller General's Department. The search criteria were secondary malignant neoplasm of bone and bone marrow patients (International Classification of Diseases 10th revision, Thai modification codes [ICD 10-TM], C79.5 and C79.8) who underwent spinal surgical treatment (ICD 9th revision, clinical modification procedure with extension codes [ICD 9-CM], 03.0, 03.4, 03.09, and 81.0) during 2005-2014. Epidemiology, comorbidity, and perioperative complication were analyzed. Results : During the study period, the number of spinal metastasis patients who underwent operative treatment was significantly increased from 0.30 to 0.59 per 100000 (p<0.001). More males (56.14%) underwent surgical treatment for spinal metastasis than females. The most common age group was 45-64 (55.1%). The most common primary tumor sites were the unknown origin, lung, breast, prostate, and hepatocellular/bile duct. Interestingly, the proportion of hepatocellular/bile duct, breast, and lung cancer was significantly increased (p<0.001). The number of patients who had comorbidity or in-hospital complication significantly increased over time (p<0.01); however, the in-hospital mortality rate decreased. Conclusion : During the last decade, operative treatment for spinal metastasis increased in Thailand. The overall in-hospital complication rate increased; however, the in-hospital mortality rate decreased.

  • Objectives: Advanced malignant melanoma (MM) has a poor prognosis, with an expected 2-year survival rate of 10 to 20%. It has long been recognized as an immunogenic tumor, and is worse for elderly patients. Many studies have suggested that herbal treatments improve immune functions, but few clinical studies have reported on this topic. Patients and History: We present two cases of female patients (72 and 77 years old, respectively) with advanced MM. The 72-year-old female patient was, at first, diagnosed with MM with multiple bone metastases. She received resection of the primary lesion, but refused further chemotherapy. The 77-year-old female patient was diagnosed with cutaneous MM of the left heel, with suspicion of sentinel node lymphadenopathy; however, she also refused any conventional treatment due to old age. Course of Therapy and Results: Both patients were exclusively treated with standardized allergen-removed Rhus verniciflua stokes (aRVS) extract combined with Bojungikki-tang (BT, Bu-Zhong-Yi-Qi-Tang in Chinese or Hochu-ekki-to in Japanese). Both patients are still alive and doing well (Feb. 2014), demonstrating that the 72-year-old patient has lived for 27 months and the 77-year-old patient has lived for 31 months without disease progression since the aRVS and BT administration. Conclusion: We suggest that the combination of aRVS extract and BT could be a candidate for overcoming the cancer's immunoediting process especially for elderly MM patients intolerant of conventional treatment.

  • Tuberculous spondylitis is a very rare disease, but it can result in bone destruction, kyphotic deformity, spinal instability, and neurologic complications unless early diagnosis and proper management are done. Because the most common symptom of tuberculous spondylitis is back pain, it can often be misdiagnosed. Atypical tuberculous spondylitis can be presented as a metastatic cancer or a primary vertebral tumor. We must make a differential diagnosis through adequate biopsy. A 30-year-old man visited our clinic due to back and chest pain after a recent traffic accident. About 1 year ago, he had successfully recovered from tuberculous pleurisy after taking anti-tuberculosis medication. We performed epidural and intercostal blocks but the pain was not relieved. For the further evaluation, several imaging and laboratory tests were done. Finally, we confirmed tuberculous spondylitis diagnosis with the biopsy results.

  • Primary xanthoma of the bone is a rare benign neoplasm, and it is extremely rare to find this in the ribs. It is most commonly reported in soft tissue and it associated with hyperlipoproteinemia. A 54-years-old male who complained of left chest pain had an X-ray taken. It revealed a left 3rd rib tumor. The blood examinations for lipid and protein were normal. A resection was done for tissue examination. The mass was histolopathologically diagnosed as a xanthoma.

  • Glioblastoma multiforme (GBM) is located most frequently in the cerebral hemispheres. Glioblastoma presenting as an extraaxial mass of cerebellopontine angle (CPA) is very rare in adults. We report a rare case of GBM arising in the CPA. The patient was a 71-year-old female, who complained of progressive gait disturbance and poor memory. Initial magnetic resonance imaging (MRI) revealed a $1.4{\times}1.3cm$ mass in the left CPA, with broad base to the petrous bone, showing homogenous enhancement. Follow-up MRI showed a rapid increase in size of mass ($2.7{\times}2.2cm$) with a necrotic portion. A stereotactic biopsy was done under the guidance of navigation system, and the histopathologic diagnosis was GBM, World Heath Organization grade IV. Further surgical resection was not performed considering her general condition, and the patient underwent concurrent chemotherapy with radiation therapy. Although rare, the possibility of glioblastoma should be included in the differential diagnosis of atypical CPA tumor.

  • Osteosarcoma is the most common primary malignancy of bone, and patients often develop pulmonary metastasis. The mechanisms underlying osteosarcoma metastasis remain to be elucidated. Recently, anti-inflammatory agents were shown to be useful in the treatment of tumor progression. We previously isolated a natural anti-inflammatory peptide from the seahorse Hippocampus kuda bleeler. Here, we examined the antitumor metastatic activity of this peptide and investigated its mechanism. The peptide significantly inhibited 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced invasive migration of human osteosarcoma MG-63 cells. Its inhibitory effect on invasive migration was associated with reduced expression of matrix metalloproteinases (MMP1 and MMP2). In addition, TPA stimulation increased intracellular reactive oxygen species (ROS) generation and small GTPase Rac1 expression, whereas the peptide decreased ROS generation and Rac1 activation. Taken together, these results suggest that the peptide inhibits invasive migration of MG-63 osteosarcoma cells by inhibiting MMP1 and MMP2 expression through downregulation of Rac1-ROS signaling.

  • Cemento-ossifying fibromas are benign tumors, and, although cases of an aggressive type have been reported, no cases of cemento-ossifying fibroma transforming into osteosarcoma have been documented previously. Low-grade osteosarcoma is a rare type of primary bone tumor, representing 1%-2% of all osteosarcomas. A 45-year-old female patient was diagnosed with cemento-ossifying fibroma, treated with mass excision several times over a period of two years and eight months, and followed up. After biopsy gathered because of signs of recurrence, she was diagnosed with low-grade osteosarcoma. The patient underwent wide excision, segmental mandibulectomy, and reconstruction with fibula free flap. The aim of this report is to raise awareness of the possibility that cemento-ossifying fibroma can transform into osteosarcoma and of the consequent necessity for careful diagnosis and treatment planning.

  • Although papillary carcinoma of the thyroid generally follows an indolent course characterized by slow growth and the absence of distant metastases, several available reports suggest that metastasis to bone and/or lung parenchyma may occur infrequently. But pleural metastases are known to be very rare, so there have been only two case reports about the pleural metastases of papillary thyroid carcinoma in the literatures. Even the case of occult papillary thyroid carcinoma presenting as a metastatic pleural effusion has been never been reported. Recently we experienced a case with the chief complaint of dyspnea due to massive pleural effusion, the cytologic examination of which revealed the papillary carcinoma with psamomma bodies. The examination of the thyroid revealed no definite primary tumor. The total thyroidectomy was done with the plan of post-operative radioactive iodine treatment and the pathologic result confirmed the occult papillary microcarcinoma as expected. With the present case report, the extension of the clinical spectrum. of metastatic papillary carcinoma of the thyroid is expected.
