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.

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.

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.

BOOP(Bronchiolitis Obliterans Organizing Pneumonia) is an inflammatory reaction that follows damage to the bronchiolar epithelium of the small conducting airways. BOOP is characterized by the pathologic finding of excessive proliferation of granulation tissue within the respiratory bronchioles, alveolar duct and spaces, accompanied by organizing pneumonia. BOOP may result from diverse causes such as toxic fumes, connective tissue disorders, infections, organ transplantation and drugs or appear idiopathically. Drug induced BOOP has been described in association with acebutolol, amiodarone, cephalosporin, bleomycine, tryptophan, gold salts, barbiturates, sulfasalazine, and carbamazepine. Carbamazepine is an iminostilbene derivative that is used as both and anticonvulasnt and pain reliever for pains associated with trigeminal neuralgia. It is structually related to the tricyclic antidepressants. To our knowledge, there have been no previously reported case that has described development of BOOP during carbamazepine treatment in Korea, and only two cases have been reported in the world. We report a case of carbamazepine-induce BOOP with a brief review of literature.

A persistent left superior vena cava(SVC) is found in about 0.3% of healthy individuals and 4.3% of patients with congenital heart disease. This anomaly is most frequently found in conjunction with a right-sided SVC, but may also be solitary. Recently, we experienced a case of persistent left SVC in patient with chronic renal failure. He required subclavian catheterization for hemodialysis due to leakage of peritoneal dialysate into external genitalia and pleural cavity. Because he had had a history of right subclavian catheterization for hemodialysis 3 months ago, the hemodialysis catheter was inserted in the left subclavian vein without any complication. Chest X-ray after insertion of the catheter showed that the distal tip of the catheter seemed to be within the aorta. Venography showed that the catheter was located within the left SVC and MRI showed isolated two SVC. He is receiving hemodialysis through the left subclavian catheter which is positioned within the left SVC without any problem.

Serum aspartate aminotransferase (AST) is a common enzyme for the evaluation of the hepatic, muscular and cardiac diseases and is produced also at kidney, brain, pancreas, lung, leukocytes, erythrocytes, etc. The elevation of its activity is usually caused by the necrosis of hepatocytes when there are not muscular injuries or myopathies. Recently, it is found that AST can exist as a macroenzyme by forming a complex with an immunoglobulin and this complex is erroneously considered to indicate the presence of liver disease as a result of elevation of AST activity on routine blood chemistry analysis. We experienced the patient with isolated AST elevation due to the formation of AST-mmunoglobulin complex confirmed by AST isoenzyme electrophoresis (EP).

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.

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.
