A Case of Membranous Glomerulonephritis with Superimposed Anti-Neutrophil Cytoplasmic Antibody-Associated Rapidly Progressive Crescentic Glomerulonephritis / 전남의대학술지

Idiopathic membranous glomerulonephritis (IMGN) is commonly diagnosed in adults with proteinuria. Rapid deterioration of renal function is a rare complication of IMGN, except when accompanied by renal vein thrombosis, malignant hypertension, or other underlying disease, including lupus nephritis. Here, we present a case of rapid deterioration of renal function in a patient with MGN superimposed with anti-neutrophil cytoplasmic antibody (ANCA)-associated rapidly progressive crescentic glomerulonephritis (RPGN). Overall, about 20 cases of MGN with ANCA-associated RPGN have been reported. This case of biopsy-proven MGN with ANCA-associated RPGN is the first to be reported in Korea.

Long-Term Survival after T-cell Lymphoblastic Lymphoma Treated with One Cycle of Hyper-CVAD Regimen / Journal of the Korean Cancer Association, 대한암학회지

T-lymphoblastic lymphoma (T-LBL) is a rare form of aggressive non-Hodgkin's lymphoma. The standard approach for management of T-LBL involves intensive multiagent chemotherapy regimens for induction and consolidation phases with central nervous system prophylaxis and a maintenance phase lasting 12-18 months. We report on a case of long-term survival after one cycle of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) and high-dose methotrexate. A 30-year-old woman diagnosed with T-LBL with a large mediastinal mass underwent one cycle of hyper-CVAD. Four days after the start of treatment, the mediastinal mass was markedly reduced. Treatment continued with one cycle of consolidation chemotherapy, comprising high-dose methotrexate and high-dose cytarabine. The patient then refused all further chemotherapeutic treatment. Seven years have passed without relapse.

A Case of Different Organ Responses to Immunosuppressive Therapy In a Microscopic Polyangiitis Patient with Interstitial Lung Disease / 대한내과학회지

Microscopic polyangiitis (MPA) is an idiopathic autoimmune disease characterized by systemic vasculitis associated with antineutrophil cytoplasmic autoantibodies. Interstitial lung disease is a less recognized manifestation of MPA and has a poor prognosis. A 61-year-old man presented with persistent cough, sputum and dyspnea. Laboratory examination revealed microscopic hematuria and renal insufficiency. Perinuclear anti-neutrophil cytoplasmic autoantibodies were positive according to serological testing. Computed tomography scans showed bibasilar reticulation and honeycombing in a peripheral distribution. Therefore, renal biopsy was performed, and MPA was diagnosed. After treating with corticosteroids and immunosuppressive agents, the patient had a complete renal response but progressive interstitial lung disease. We report a case of MPA presenting with interstitial lung disease in which the patient experienced different responses in each organ.

A Case on Streptococcal Pneumonia Associated with Leptomeningitis, Osteomyelitis and Epidural Abscess in a Patient with AIDS / 결핵및호흡기질환

Patients with acquired immunodeficiency syndrome (AIDS) are at higher risks of bacterial pneumonia than the general population, and the pathogen is the most commonly involved Streptococcus pneumoniae. We hereby report a case of pneumococcal pneumonia associated with leptomeningitis, osteomyelitis and epidural abscess in a patient with AIDS. He is being successfully treated with ampicillin/sulbactam and clindamycin. And because the pneumococcal infection is usually associated with morbidity and mortality rates in the setting of AIDS, we should consider for pneumococcal vaccinations among the AIDS populations.

Pathological differences between forceps biopsy specimens and endoscopic resection specimens in early gastric cancer patients / 고신대학교의과대학학술지

OBJECTIVE: Endoscopic resection(ER) is effective therapy on EGC and which is treated according to the histological diagnosis of forcep biopsy. But sometimes the histological diagnosis of forcep biopsy and post-ER does not match with each other and it might lead to wrong treatment. The aim of this study is to find the frequency of histologic differences between forcep biopsy and post-ER, and to confirm the characteristics of lesions which make errors. METHODS: We selected the confirmed cancer cases of 141 patients of 1359 gastric tumor lesions which were treated under the ER in Eulji university hospital from May 2005 to March 2013. They were sorted by the age and sex of patient, location of lesion, present of ulcer and depression to identify the discordance between forcep biopsy and ER. The discordant group was compared with non-cancer-diagnosed controlled group, retrospectively. RESULTS: 70 cases(5.5%) of 1283 cases of "cancer negative" in forceps biopsy were found to be diagnosed cancer on final diagnosis of cancer by post-ER result. In this discordant group showed characteristics of bigger size that are with more frequently in tumor size >==15mm(17.9% vs. 31.4%, p=0.03), have depressed lesion(14.3% vs. 41.4%, p==15mm, presented with depressed lesion and ulceration, we should consider combined cancer, even the result of forcep biopsy was negative. Therefore, more careful and accurate resection should be taken with characters listed above.

Mycotic Abdominal Aortic Aneurysm Caused by Bacteroides Thetaiotaomicron and Acinetobacter Lwoffii: The First Case in Korea / 감염과화학요법

Mycotic aneurysms are uncommon, but are fatal without appropriate management. Previous reports have shown that anaerobes and gram-negative organisms are less common but more dangerous than other causative agents of mycotic aneurysm. We report the case of a 60-year-old man with poorly controlled diabetes mellitus and atherosclerosis in the aorta, and a 10-day of history of lower abdominal pain and fever. This man was diagnosed with an uncommon abdominal aorta mycotic aneurysm caused by Bacteroides thetaiotaomicron and Acinetobacter lwoffii. The aneurysm was successfully treated with antibiotics therapy and aorto-bi-external iliac artery bypass with debridement of the infected aortic wall. We present this case together with a review of the relevant literature.

Percutaneous Closure of an Iatrogenic Ventricular Septal Defect Following Concomitant Septal Myectomy at the Time of Aortic Valve Replacement

A 77-year-old female patient underwent aortic valve replacement (AVR) with concomitant septal myectomy and tricuspid annuloplasty. Her symptoms did not improve after a successful operation. Echocardiogram demonstrated the presence of an iatrogenic ventricular septal defect (VSD). It was muscular in location and not the usual AVR with membraneous type of VSD, suggesting a complication from the myectomy. Percutaneous closure of the VSD remained the only feasible option due to her poor overall medical status. A 14-mm Amplazter VSD occluder was deployed successfully, by means of the trans-septal technique. She has improved very well postoperatively.

Primary Synovial Sarcoma of the Lung With Rapid Progression in an Old Age Female

Synovial sarcoma comprises approximately 10% of soft tissue sarcomas. Primary pulmonary synovial sarcoma is a rare tumor. It makes up only 0.5% of all primary lung malignancies. It typically presents in adolescents and young adults. The usual progress of the tumor is unknown. We report the rapid progress of a primary pulmonary sarcoma that developed in a 67-year-old woman. In this case, metastatic sarcoma was excluded by positron emission tomography-computed tomography. Synovial sarcoma was histologically confirmed by a biopsy from the lung tissue. The patient had two masses located at the upper lobe of the lung. The patient refused all medical treatment and left our hospital. Two months later, she was readmitted and diagnosed with multiple metastases in the other lung and pancreas. She expired due to syndrome of inappropriate antidiuretic hormone secretion and superior vena cava syndrome four days after admission.
