Aneurysmal bone cyst(ABC) is a benign lesion and generally occurs in the long bones and vertebral column. ABC of the rib is an uncommon entity. We reported a case of ABC originating in the left first rib. The patient was a 19-year-old woman and presented with palpable mass on the shoulder. Chest X ray and MRI showed a large expansile mass, with multiple cystic areas, arising from the left first rib and bulging out into retroclavicular and paravertebral soft tissue, so the lesion was initially misdiagnosed as a soft tissue malignant tumor destructing adjacent rib. On histological examination, the mass, which was surrounded by a peripheral band of mature trabecular bone, consisted of multiple anastomosing cavernous blood channels separated by fibrous septa that containing osteoid, myxochondroid material and osteoclast-type giant cells.

Sodium iodide symporter (NIS) plays a key role in thyroid hormone production by efficiently accumulating iodide from the circulating blood into the thyocytes, and this is done against an electrochemical gradient. Thyroid transcription factor-l (TTF-l) is a homeodomain-containing protein expressed in embryonic diencephalons, thyroid, and lung and has been found to bind to thyroid specific promoters and to activate their transcriptional activity. TTF-l may be one of the factors capable of activating NIS gene expression in the thyroid gland, thus it accounts for the lower levels of NIS gene expression that are seen in the extrathyroidal tissues. However, a high frequency of TTF-l expression has been observed, especially in primary lung adenocarcinoma. The present study was undertaken in order to elucidate the relationship between the expression of NIS and TTF-l in primary lung adenocarcinoma. Immunohistochemical studies for NIS and TTF-l were performed in 64 primary lung adenocarcinomas. Immunoreactivities for NIS and TTF-l were found in 49 (76.6%) and 45 (70.3%) out of 64 cases, respectively. Forty-one (83.7%) of the 49 cases with positive NIS immunoreactivity showed positive TTF-l expression, whereas 11 (73.3%) of the 15 cases with negative NIS immunoreactivity showed negative TTF-l expression (P<0.05). So the NIS expression was significantly associated with the TTF-l expression. These findings suggest that TTF-l may be one of the factors capable of activating NIS gene expression in primary lung adenocarcinoma. Further studies are needed to define the relation between NIS and TTF-l for examining the mechanisms of tissue-specific NIS expression.
Purpose: Non small cell lung cancer (NSCLC) is the leading worldwide source of cancer-related deaths. Although some drugs targeting EGFR mutations have been developed, most advanced cases are still incurable. New targets for anticancer drugs are demanded. The kringle 1 domain of hepatocellular growth factor alpha chain (HGFK1) is a potent anti-angiogenesis factor. It has also emerged as a potential anticancer factor in hepatocellular carcinoma (HCC). The expression of HGFK1 protein in patients with NSCLC has not been reported to date. Method: Here, we assessed HGFK1 expression by Western blotting in 103 cases with advanced NSCLC to investigate the impact of HGFK1 on survival. Results: Results revealed 33 (30.1%) patients were classified as high expressors, this being significantly associated with less remote metastasis (P = 0.002) but not with lymph node metastasis (P = 0.062). There was also a significant association between HGFK1 expression and tumor size (P = 0.025) as well as clinical stage (P = 0.012). Kaplan-Meier survival analysis showed that both overall survival (OS) and progression free survival (PFS) of patients with HGFK1 expression were longer than those of patients without HGFK1 expression (P = 0.004 and P = 0.001 respectively). HGFK1 reversed gefitinib inhibition in the resistent NSCLC cell line A431/GR but did not inhibit the proliferation of NSCLC cells A431 and A431/GR directly. Reversion of gefitinib inhibition in A431/GR cells by HGFK1 was related to decreased phosphorylation of ERK and STAT5. Conclusions: HGFK1 may be a useful prognostic factor of advanced NSCLC patients and a potential drug for gefitinib resistant patients.
Purpose : To evaluate the treatment outcome for patients with locally advanced, unresectable esophageal cancer treated with relatively high dose radiation therapy(RT). Materials and Methods : From January 2000 to December 2008, 32 patients with locally advanced unresectable or medically inoperable esophageal cancer were treated with radiation therapy(RT) with or without concurrent chemotherapy. Ten patients were excluded from analysis because of distant metastasis and drop off. Patient distributions according to AJCC stages II, III IVa were 7(31.8%), 12(54.6%), 3(13.6%) respectively. The locations of tumor were cervical/upper thorax 3 (13.6%), mid thorax 13(59.1%), and lower thorax/abdominal 6(27.3%), respectively. Eleven patients received RT only, and 11 patients received cisplatin based concurrent chemoradiotherapy(CCRT). Median radiation dose was 65 Gy(range 57.6~72 Gy). Results : The median follow-up was 9.1 months(range 1.9~43.8 months). The response rates for complete response, Partial response, stable disease and Persistent disease were 6(27.3%), 11(50.0%), 4(18.2%) and 1(4.5%), respectively. Two patients(9.1%) suffered from esophageal stenosis and stents were inserted. Two patients(9.1%) had Grade 3 radiation pneumonitis and one of them expired due to acute respiratory distress syndrome(ARDS) at 36 days after completion of radiation therapy. The recurrence rate was 11(50.0%). The patterns of recurrence were persistent disease and local progression in 5(22.7%), local recurrence 3(13.7%) and concomitant local and distant recurrence in 3(13.7%). The overall survival(OS) rate was 32.1% at 2 years and 21.4% at 3 years(median 12.0 months). Disease free survival(DFS) rate was 17.3% at 2 and 3 years. All patients who had no dysphagia at diagnosis showed complete response after treatment and 100% OS at 3 years(p=0.0041). The OS for above 64.8 Gy group and 64.8 Gy or below group at 3 years were 60.6% and 9.1%(p=0.1341). The response to treatment was the only significant factor affecting OS(p=0.004). Conclusion : Relatively high dose radiation therapy in unresectable esophageal cancer tended to have a better outcome without increased complication rate. Further study with more patients is warranted to justify improved result.
For patients receiving chemotherapy and radiation therapy treatment progresses as vomiting, nausea, weight of the patient because of a loss of appetite it is reduced. The patient's weight and the distance from the skin and the treatment site is expected to be closer, thereby reducing the change in the skin because of this dose. This study tests using a loose see the difference between the volume change appears as the weight of the patient using the same phantom and the phantom body of the patient. To using the same as the position EBT film is attached to the skin of the treatment site and was adjusted to the thickness of the Bolus. And using a computerized treatment planning only tomotherapy equipment was passed under the conditions according to the thickness of the radiation dose. To baseline for accurate reproduction position using the MVCT was applied to treated with verification. By passing a total of three dose reduced the error, it was a measure of the film by using a dedicated scanner, EBT VIDAR scanner. Got an increase in the skin dose is displayed each time the thickness of the bolus reduced, in a bolus was completely removed with the highest value. If the changes appeared dose was greater weight loss patients to chemotherapy and therefore bolus thickness variation considering the weight loss of the patient when applying the tomotherapy of nasopharynx cancer was found that the increase in skin dose be increased. This large patient before treatment due to weight loss over the image verification is considered to be established should consider how to re-create your mask and treatment plan for fixing it.

Background: There are a million ragpickers in India who gather and trade recyclable municipal solid wastes materials for a living. The objective of this study was to examine whether their occupation adversely affects their immunity. Methods: Seventy-four women ragpickers (median age, 30 years) and 65 age-matched control housemaids were enrolled. Flow cytometry was used to measure leukocyte subsets, and leukocyte expressions of $Fc{\gamma}$ receptor I (CD64), $Fc{\gamma}RIII$ (CD16), complement receptor 1 (CD35) and CR3 (CD11b/CD18), and CD14. Serum total immunoglobulin-E was estimated with enzyme-linked immunosorbent assay. Results: Compared with the controls, ragpickers had significantly (p < 0.0001) higher levels of CD8-T-cytotoxic, CD16+CD56+natural killer, and CD4+CD45RO+memory T-cells, but depleted levels of CD19+B-cells. The percentage of CD4+T-helper-cells was lower than the control group (p < 0.0001), but their absolute number was relatively unchanged (p = 0.42) due to 11% higher lymphocyte counts in ragpickers. In ragpickers, the percentages of CD14+CD16+intermediate and CD14dim CD16+nonclassical monocyte subsets were elevated with a decline in CD14+CD16-classical monocytes. The expressions of CD64, CD16, CD35, and CD11b/CD18 on both monocytes and neutrophils, and CD14 on monocytes were significantly higher in ragpickers. In addition, ragpickers had 2.7-times more serum immunoglobulin-E than the controls (p < 0.0001). After controlling potential confounders, the profession of ragpicking was positively associated with the changes. Conclusion: Ragpicking is associated with alterations in both innate (neutrophils, monocytes, and natural killer cell numbers and expression of complement and $Fc{\gamma}$ receptors) and adaptive immunity (numbers of circulating B cells, helper, cytotoxic, and memory T cells).
From Nov. 1983 through Jan. 1986, 43 patients with nonsmall cell lung cancer were treated by radiation therapy at Inje Medical College Paik Hospital. 38 patients were available for the analysis of this study. 33 patients received definite irradiation with curative intent, while 5 patients received postoperative irradiation. Chemotherapy was added in 12 patients before, during and after radio-therapy. 28 patients were squamous cell carcinoma and 10 patients were adenocarcinoma. There were 29 men and 9 women (median age, 50 years; range 34 to 74 years). Stage 1 was 1 patient, Stage 11,7 patient, and Stage 111,30 patients. Among 33 patients who received radiotherapy with curative intent, follow up radiological study revealed complete response in 12 patients $(36\%)$, partial response, in 9 patients $(27\%)$, and minimal response, in 5 patients $(15\%)$, while 7 patients $(21\%)$ were nonresponders. Median survival for all patients was 6.9 months; squamous cell carcinoma, 7.3 months, adenocarcinoma, 5.9 months. Responders survived median 7 months, while nonresponders survived median 1.9 months. Improved complete response rate and survival were shown in high radiation dose group. As prognostic factors, age, initial performance status, sex, histology and tumor location were evaluated.
Lymphocytic interstitial pneumonitis (LIP) is one of parenchymal pulmonary infiltrative diseases first described at 1966 by Carrington and Liebow. In LIP, there is a predominance of mature small lymphocytes in the interstitium of the lung which form germinal centers. The disease process surrounds, but dose not invade lung parenchyme, tracheobronchial tree and vascular structures. The etiology remains still unknown and the clinical features of this disorder have not been clearly defined. Therefore, the therapeutic modality is obscure. Development of LIP association with AIDS is often reported currently and possibility of progress to malignant lymphoma is emphasized. We experienced a case of primary LIP with pnemomediastinum. She was adimitted due to chest and anterior nuchal pain with chronic coughing, and diagnosed as pneumomediastinum with LIP. Medication with steroid was begun and some improvement of symptoms was observed, but an X-ray film of the chest remained same without improvement. We report above case with review of the literatures.
Churg-Strauss syndrome is a rare form of systemic necrotizing vasculitis that occurs exclusively in patients with asthma, and is associated with blood and tissue eosinophilia. The classic pathology findings in the lung include a combination of eosinophilic pneumonia, granulomatous inflammation and necrotizing vasculitis. However, there are few reports of tracheobronchial mucosal lesions in Churg-Strauss syndrome. We report a case of Churg-Strauss syndrome with multiple tracheobronchial mucosal lesions in a 33-year-old man with a history of bronchial asthma and allergic rhinitis. He had been diagnosed with community acquired pneumonia at another hospital and was treated with antibiotics. However, the chest radiographic findings were aggravated and showed multifocal consolidations in the whole lung fields. He was transferred to the Asan Medical Center. Fiberoptic bronchoscopy revealed multiple nodular mucosal lesions of the trachea and bronchi. The histopathology of the mucosal lesions revealed necrotizing bronchial inflammation with eosinophilic infiltration. Video Assisted Thoracic Surgery was performed. The wedge resected lung tissue revealed chronic eosinophilic pneumonia that was consistent with Churg-Strauss syndrome. Methylprednisolone (1 mg/kg q 8 hr) was prescribed and his symptoms resolved gradually. The chest radiographic findings improved significantly, and a follow-up fiberoptic bronchoscopy performed eight days later showed that the tracheobronchial mucosal lesions had resolved. The patient was prescribed oral prednisolone for 20 months after discharge. Currently, the patient is not taking steroids and is being followed up.
The purpose of the study was to explore the effect of 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hour on the frequency of "red man syndrome", phlebitis and length of peripheral catheter placement of infected patients, in order to provide safe infusion method for reducing vancomycinin-duced RMS and phlebitis. The subjects of the study consisted of 16 hospitalized patients; 3 oncology and gastro-intestinal patients, 1 neurological patient, 6 thoracic surgical patients and 6 orthopedic patients, who had received vancomycin from July to October in 1999 at S-hospital. The dependent variables were the incidence of RMS, phlebitis and the length of peripheral catheter placement. The incidence of RMS was checked by an inspector at the first night whenever the infusion method of vancomycin was changed. RMS was observed every 15 minutes during an hour for symptoms of RMS such as itching, erythema, chest pain and systolic blood pressure. Incidence of phlebitis was assessed by inspector twice a day from the insertion of peripheral catheter to the removal of the catheter. The data were analyzed by percentage, mean, $X^2$-test, t-test, repeated ANOVA, and logistic regression analysis using the SPSSWIN program. The results are summarized as follows; 1. No significant difference was identified in frequency of RMS between the experimental group and control group. 2. There was no significant difference in the change of systolic blood pressure as the time goes on between the experimental group and control group. 3. The incidence of phlebitis was significantly lower in the experimental group than in the control group. 4. The length of peripheral catheter placement was significantly longer in the experimental group than in the control group. 5. Other drugs administrated with vancomycin didn't influence the occurrence of phlebitis. However, the infusion method of vancomycin influenced the occurrence of phlebitis. The results suggest that 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hours may decrease the incidence of phlebitis and increase the length of peripheral catheter placement compared to 1 hour infusion of vancomycin(1g) in 100ml of isotonic saline every 12 hours. However, it does not reduce the incidence of RMS.
