Purpose:
This study aimed to evaluate the role of postoperative radiotherapy (PORT) in intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC).
Materials and Methods:
A total of 133 patients with histologically confirmed HPC were included from eight institutions. Gross total resection (GTR) and subtotal resection (STR) were performed in 86 and 47 patients, respectively. PORT was performed in 85 patients (64%). The prognostic effects of sex, age, performance, World Health Organization (WHO) grade, location, size, Ki-67, surgical extent, and PORT on local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) were estimated by univariate and multivariate analyses.
Results:
The 10-year PFS, and OS rates were 45%, and 71%, respectively. The multivariate analysis suggested that PORT significantly improved LC (p < 0.001) and PFS (p < 0.001). The PFS benefit of PORT was maintained in the subgroup of GTR (p=0.001), WHO grade II (p=0.001), or STR (p < 0.001). In the favorable subgroup of GTR and WHO grade II, PORT was also significantly related to better PFS (p=0.028). WHO grade III was significantly associated with poor DMFS (p=0.029). In the PORT subgroup, the 0-0.5 cm margin of the target volume showed an inferior LC to a large margin with 1.0-2.0 cm (p=0.021). Time-dependent Cox proportion analysis showed that distant failures were significantly associated with poor OS (p=0.003).
Conclusion
This multicenter study supports the role of PORT in disease control of intracranial SFT/HPC, irrespective of the surgical extent and grade. For LC, PORT should enclose the tumor bed with sufficient margin.

Severe acute pancreatitis (SAP) is associated with systemic complications and high mortality rate in dogs. Mesenchymal stem cells (MSCs) have been investigated for their therapeutic potential in several inflammation models. In the present study, the effects of canine adipose tissue-derived (cAT)-MSCs in a rat model of SAP induced by retrograde injection of 3% sodium taurocholate solution into the pancreatic duct were investigated. cAT-MSCs labeled with dioctadecyl-3,3,3′-tetramethylindo-carbocyanine perchlorate (1 × 10⁷ cells/kg) were systemically administered to rats and pancreatic tissue was collected three days later for histopathological, quantitative real-time polymerase chain reaction, and immunocytochemical analyses. Greater numbers of infused cAT-MSCs were detected in the pancreas of SAP relative to sham-operated rats. cAT-MSC infusion reduced pancreatic edema, inflammatory cell infiltration, and acinar cell necrosis, and decreased pancreatic expression of the pro-inflammatory cytokines tumor necrosis factor-α, interleukin (IL)-1β, -6, -12, -17, and -23 and interferon-γ, while stimulating expression of the anti-inflammatory cytokines IL-4 and IL-10 in SAP rats. Moreover, cAT-MSCs decreased the number of clusters of differentiation 3-positive T cells and increased that of forkhead box P3-positive T cells in the injured pancreas. These results indicate that cAT-MSCs can be effective as a cell-based therapeutic strategy for treatment of SAP in dogs.

Telomerase play a key role in the maintenance of telomere length and chromosome integrity. We have evaluated the association between telomerase activity and the risk of lung cancer in peripheral blood. Telomerase activity in peripheral blood mononuclear cells was measured by a PCR-designed telomeric repeat amplification protocol in 63 lung cancer patients and 190 healthy controls that were matched for age, gender, and smoking status. Telomerase activity was significantly lower in the lung cancer patients than in controls (mean +/- standard deviation; 1.32 +/- 1.65 vs 2.60 +/- 3.09, P < 1 x 10(-4)). When telomerase activity was categorized into quartiles based on telomerase activity in the controls, the risk of lung cancer increased as telomerase activity reduced (Ptrend = 1 x 10(-4)). Moreover, when the subjects were categorized based on the median value of telomerase activity, subjects with low telomerase activity were at a significantly increased risk of lung cancer compared to subjects with high telomerase activity (adjusted odds ratio = 3.05, 95% confidence interval = 1.60-5.82, P = 7 x 10-4). These findings suggest that telomerase activity may affect telomere maintenance, thereby contributing to susceptibility to lung cancer.

Apoptosis plays an essential role in the elimination of mutated or transformed cells from the body. Therefore, polymorphisms of apoptosis-related genes may lead to an alteration in apoptotic capacity, thereby affecting the occurrence of TP53 mutations in lung cancer. We investigated the relationship between potentially functional polymorphisms of apoptosis-related genes and TP53 mutations in non-small cell lung cancer (NSCLC). Twenty-seven single nucleotide polymorphisms in 20 apoptosis-related genes were genotyped by a sequenome mass spectrometry-based genotyping assay in 173 NSCLCs and the associations with TP53 mutations in the entire coding exons (exons 2-11), including splicing sites of the gene, were analyzed. None of the 27 polymorphisms was significantly associated with the occurrence of TP53 mutations. This suggests that apoptosis-related genes may not play an important role in the occurrence of TP53 mutations in lung cancer.

Diffuse infiltrative lymphocytosis syndrome is an autoimmune syndrome that is characterized by the oligoclonal expansion of CD8+ T-lymphocytes in response to human immunodeficiency virus (HIV) antigens. The clinical manifestations include bilateral enlargement of the parotid glands, lymphocytic interstitial pneumonitis, lymphocytic hepatitis, neurological involvement and systemic lymphadenopathies. In addition to a positive HIV test, the diagnostic histopathological findings are CD8+ T-lymphocytic infiltrations in the lymphnodes, liver, lung, muscle and the salivary or lacrimal glands without granulomatous or neoplastic involvement. We report a case of pulmonary involvement of diffuse infiltrative lymphocytosis syndrome that was associated with a human immunodeficiency virus infection.

The authors report a rare case of actinomycosis, involving the thyroid gland in a 9-year-old female, presented with a hard, non-tender, non-inflammatory left neck mass of 4 weeks duration. On physical examination a firm, non-tender mass within the left thyroid gland was found; and the laboratory and imaging studies strongly suggested a thyroid neoplasm. After a left subtotal thyroidectomy, a gross sulfur granule was founded in the excised lesion. Histological examination confirmed actinomycotic thyroiditis. Actinomyces species are a very rare cause of infective thyroiditis, with difficulties in their diagnosis and treatment. The authors reviewed its pathogenesis and treatment.

We present a case of xanthogranulomatous cholecystitis which involved the liver and clinically mimicked gallbladder carcinoma, and review the associated literature. A 72- year-old woman was admitted to our hospital because of intermittent, right upper quadrant, abdominal pain. Computed tomography showed a large-mass in the gallbladder with findings that seemed to indicate invasion of the liver. During laparotomy, the gallbladder showed signs of chronic cholecystitis, and a cholecystectomy was performed. Histopathological diagnosis was xanthogranulomatous cholecystitis.

A bronchial artery aneurysm(BAA) is rare, and has an unclear etiology. However, it may be caused by conenital abnormalities and acquired diseases like as bronchiectasis, tuberculosis, and other infections. The pathogenesi s of a bronchial artery dilatation and the formation of an aneurysm results in an increase in the systemic blood flow to the chronic inflammatory pathologic lungs such as bronchiectasis or tuberculosis. It can be divided into the mediastinal and intrapulmonary BAA according to their location. The most common symptom is hemoptysis. Chest computed tomography and bronchial artery angiography may be used for a diagnosis. Treatment is mainly by a surgical resection of the aneurysmal artery. However, when patient is unstable due to massive hemoptysis or recurrent hemoptysis, bronchial artery embolization is useful. Here, we experienced a case of a bronchial artery aneurysm presenting as a massive hemoptysis.

Lymphocytic interstitial pneumonitis (LIP) is characterized by diffuse bilateral pulmonary infiltrations in both lower lobes. Pleomorphic lymphohistiocytes including mature lymphocytes, variable admixture of plasma cells and other mononuclear cells infiltrate within the pulmonary interstitium, ranging from widened septa to confluent masses. We report a case of LIP associated with Epstein-Barr virus in a patient with SLE and Sj gren's syndrome. A 50-year-old woman was admitted with insidious onset of progressive dyspnea for 20 days. She suffered from arthritis 10 years earlier without specific diagnosis. A radiography of chest has showed bilateral consolidative infiltrations with pleural effusion in both lower lung fields. Open lung biopsy documented lymphocytic interstitial pneumonitis which expressed Epstein-Barr virus genome in situ hybridization study. Following corticosteroid and cyclophosphamide therapy, clinical symptoms and radiologic infiltrations gradually remitted.

Although excessive arteriovenous fistula blood flow may be a factor in the development of high-output cardiac failure, this diagnosis is easily over-looked. Surgical reduction of fistula blood flow can improve the condition. We here report a case of high-output cardiac failure due to excessive arterio-venous fistula blood flow in a hemodialysis patient. A 51-year-old man who had been treated with hemodialysis since 5 years ago was admitted for increasing cardiac failure. Echocardiographic evaluation of cardiac output and duplex measurement of the fistula confirmed the diagnosis of high-output cardiac failure due to excessive arteriovenous fistula blood flow. After surgical closure of the fistula, the signs and symptoms of cardiac failure subsequently subsided and both systolic and diastolic dimension of left ventricle much decreased.
