Granuloma faciale is a rare disease of unknown origin characterized by single or multiple cutaneous nodules usually occurring on the face. A narrow grenz zone of normal dermis is usually observed between the epidermis and the dense dermal polymorphous infiltrates. We report a case of granuloma faciale in a 40-year-old male patient with erythematous plaque on his nose. The skin biopsy specimen showed a dense dermal accumulation of inflammatory cells, including neutrophils, eosinophils, monocytes, and lymphocytes. The infiltrate was distributed diffusely throughout the involved dermis and it focally involved the thinned and flattened epidermis. There is deposition of fibrinoid material within and around the affected lood wessels. The lesion was treated with CO2 laser effectively.

It is known that neutropenia caused by combination pegylated interferon plus ribavirin therapy for hepatitis C virus (HCV) infection is well tolerated and carries a negligible risk of infection. Neutropenic enterocolitis is encountered most frequently in patients with hemato-oncologic diseases who are undergoing intensive chemotherapy. However, little information exists regarding this life-threatening event in the setting of HCV therapy. We present here an unusual case of fatal neutropenic enterocolitis in a cirrhotic patient receiving combination therapy for HCV infection. This is the first report of a death from neutropenic enterocolitis associated with treatment for chronic HCV infection. The present case suggests that caution should be exercised when continuing HCV therapy in neutropenic patients with advanced fibrosis, and the decision to maintain such therapy should be balanced against the potential for serious adverse events.

Epithelioid hemangioendothelioma is a neoplasm of vascular origin with a low-to-intermediate malignant potential and is one of the rare sarcomas arising from the liver. Its etiology is unknown and its clinical outcome is unpredictable. There is no generally accepted therapeutic strategy because of its rarity and the variable natural course between hemangioma and angiosarcoma. We report a case of a 64-year old woman who underwent hepatic resection due to epithelioid hemangioendothelioma in the right lobe that progressed to extrahepatic metastases of the bone, pleura, and peritoneum 22 months later. However, after resection there was no primary hepatic recurrence.

Although continuous low-dose (metronomic [MET]) therapy exerts anti-cancer efficacy in various cancer models, the effect of long-term MET therapy for hepatocellular carcinoma (HCC) remains unknown. This study assessed the long-term efficacy of MET on suppression of tumor growth and spontaneous metastasis in a rat model of HCC induced by administration of diethylnitrosamine for 16 wk. The rats were divided into 3 groups: MTD group received intraperitoneal (i.p.) injections of 40 mg/kg cyclophosphamide on days 1, 3, and 5 of a 21-day cycle; Control and MET groups received i.p. injections of saline and 20 mg/kg cyclophosphamide twice a week, respectively. Anti-tumor and anti-angiogenic effects and anti-metastatic mechanisms including matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) were evaluated. Twelve wk of MET therapy resulted in a significant reduction in intrahepatic tumors than control or MTD therapy. The MET group had fewer proliferating cell nuclear antigen-positive cells and decreased hypoxia-inducible factor-1alpha levels and microvessel density. Lung metastases were detected in 100%, 80%, and 42.9% in the control, MTD, and MET groups, respectively. MET therapy significantly decreased expression of TIMP-1, MMP-2 and -9. For mediators of pro-MMP-2 activation, MET therapy induced significant suppression in the TIMP-2 and MMP-14 level. The survival in the MET group was significantly prolonged compared to the control and MTD groups. Long-term MET scheduling suppresses tumor growth and metastasis via its potent anti-angiogenic properties and a decrease in MMPs and TIMPs activities. These results provide a rationale for long-term MET dosing in future clinical trials of HCC treatment.

Macrophage activation syndrome (MAS) is one of the serious complications of juvenile rheumatoid arthritis (JRA) and recently, cyclosporine A has been found to be effective in patients with corticosteroid-resistant MAS. A 29-yr-old male was admitted with high fever and jaundice for one month. He was diagnosed as juvenile arthritis 16 yr ago. Physical and laboratory results showed hepatosplenomegaly, high fever, pancytopenia and impaired liver and renal function tests, elevated triglyceride and serum ferritin levels. Bone marrow biopsy showed hyperplasia of histiocytes with active hemophagocytosis. He was diagnosed as MAS associated with juvenile rheumatoid arthritis and managed with high-dose corticosteroids initially, but clinical symptoms and laboratory findings did not improve immediately. Finally, he completely recovered after treatment with cyclosporine A (3 mg/kg/day).

Hypovolemia and relative polycythemia is not an uncommon presentation in a child with nephrotic syndrome, but it is seldom mentioned in an adult. We experienced a case of hypovolemic shock and erythrocytosis in a patient with minimal change disease. Hypovolemia and polycythemia was corrected only after infusing isotonic fluid with albumin for 3 days. Hypovolemic shock is attributable to some of the following factors; suddenly decreased capillary oncotic pressure due to massive proteinuria, interstitial edema with tubular collapse, redistribution of renal blood flow, decreased glomerular filtration rate, and use of diuretics without albumin. In summary, 1) Relative polycythemia may occur as a result of hypovolemia in a patient with nephrotic syndrome but can be easily corrected by isotonic fluid and albumin. 2) An early detection of hypovolemia can be made by the measurement of central venous pressure, echocardiography, and the assessement of FeNa, U[k]/(U[Na]+U[K]). 3) Diuretics without albumin may result in transient developement of shock in patients with profound volume depletion.

The wide use of lamivudine in chronic hepatitis B has produced a monotonic increase in patients with lamivudine resistance. Therefore, treating lamivudine resistance in chronic hepatitis B is a major concern in clinical practice for the treatment of hepatitis B virus (HBV). There is conflicting evidence on the outcome of pegylated interferon alpha (PEG-IFN alpha) therapy against lamivudine-resistant HBV, which is due to mutations in the YMDD motif. We experienced a patient with chronic hepatitis B who was successfully treated with PEG-IFN alpha-2a after the development of virologic and biochemical breakthrough during lamivudine therapy. Virologic breakthrough was associated with the emergence of YMDD mutants 48 months after starting lamivudine therapy. Treatment with PEG-IFN alpha-2a for 12 months resulted in an undetectable serum level of HBV DNA and the resolution of hepatitis, and the virologic response was maintained over 16 months after cessation of PEG-IFN alpha-2a.

Although arthralgia with or without hyperuricemia commonly occurs in a patient receiving antituberculous treatment including pyrazinamide, acute gouty arthritis is rarely reported. Here we report a case of acute gouty arthritis presented after antituberculous treatment in a patient with asymptomatic hyperuricemia and mild renal insufficiency. A 76-year-old woman complained sudden onset of painful swelling in both first metatarsophalangeal joints 9 weeks after antituberculous treatment. She had hypertensive nephropathy with mild renal insufficiency and asymptomatic hyperuricemia for 8 years. Needle aspiration of the joint fluid demonstrated needle-shaped strongly negative birefringent monosodium urate crystal. The painful swelling improved with steroid and colchicine.

Most pancreatic pseudocysts are located in or around the pancreas, but they can be found in all the potential spaces around viscera in and outside of the abdominal cavity. The complications of pancreatic pseudocysts are infection, rupture, fistula, obstruction and hemorrhage. However, an upper gastrointestinal bleeding caused by pancreatic pseudocyst is rare. Pseudocysts with complication like hemorrhage require percutaneous, endoscopic or surgical treatment. We report a case of the pancreatic pseudocyst involving duodenal wall with upper gastrointestinal hemorrhage, which was improved by conservative treatment.

BACKGROUND/AIMS: Obstructive sleep apnea is becoming more important in gastroesophageal reflux disease (GERD) patients. This study investigated the prevalence of high risk for obstructive sleep apnea in GERD patients in comparison with that in healthy controls using the Berlin Questionnaire. We also investigated the risk factors for obstructive sleep apnea in GERD patients. METHODS: We enrolled 1,007 subjects: 776 healthy controls, 115 individuals with erosive reflux disease, and 116 with non-erosive reflux disease. GERD was diagnosed and classified using endoscopy and a reflux questionnaire. The Berlin Questionnaire was used to evaluate obstructive sleep apnea. RESULTS: More patients in the GERD group (28.2%) had higher risk for obstructive sleep apnea than healthy controls (20.4%, P = 0.036). More patients with non-erosive disease (32.8%) had higher risk for obstructive sleep apnea (OSA) than patients with erosive disease (20.9%) and controls (20.4%, P = 0.010). On multivariate analysis, non-erosive disease was a high risk factor for obstructive sleep apnea (odds ratio [OR], 1.82; P = 0.011). Age > or = 55 years (OR, 1.83; P < 0.001) and a high body mass index (> or = 25 kg/m2) (OR, 2.76; P < 0.001) were also identified as risk factors. Nocturnal GERD was related to high risk for OSA in non-erosive disease patients (OR, 2.97; P = 0.019), but not in erosive disease patients. CONCLUSIONS: High risk for OSA is more prevalent in GERD patients than in controls. Non-erosive reflux disease, age > or = 55, and a high BMI are associated with high risk for OSA.
