Purpose: There remains a lot of unmet need to increase understanding of node-positive (ypN+) muscle invasive bladder cancer (MIBC) after neoadjuvant chemotherapy and radical cystectomy to decide the appropriate therapeutics. Materials and Methods: In a retrospective study using the center cancer chemotherapy registry, we found 113 MIBC patients who were treated with neoadjuvant chemotherapy involving gemcitabine and cisplatin (GP) followed by radical cystectomy between 2010 and 2014. Disease-free survival (DFS) and overall survival (OS) were compared according to the pathologic node positivity (ypN- vs. ypN+). Among a total of 165 patients with MIBC who received neoadjuvant chemotherapy involving GP, 118 underwent radical cystectomy. In 46 patients with ypN+ disease, DFS and OS were evaluated according to administration of adjuvant GP. Results: After neoadjuvant chemotherapy and radical cystectomy, 41% of patients had ypN+ disease, which showed significantly shorter DFS (median, 7.4 months; 95% confidence interval [CI], 5.3–9.6 months) and OS (median, 20.0 months; 95% CI, 13.4–26.6 months) compared to those with ypN- disease. The patients with ypN+ disease had a high risk of recurrence or death, regardless of the administration of adjuvant chemotherapy or adjuvant regimen. Conclusions: Within the limitations of this retrospective study, MIBC patients with ypN+ disease despite neoadjuvant chemotherapy and radical cystectomy had a poor prognosis. Further studies involving novel, effective adjuvant treatment including immunotherapy agents are needed to reduce the high risk of recurrence or death in these patients.

Lipohyperplasia of the ileocecal valve is a rarely diagnosed lesion of unknown etiology and uncertain significance, which is characterized by diffuse infiltration of mature adipose tissue in the submucosal layer of the ileocecal valve. For endoscopists and radiologists, it has often remained difficult to make a distinction from malignant neoplasia. We describe two cases of lipohyperplasia of the ileocecal valve, all histopathologically diagnosed after major surgery. Case 1 was a 44-year-old male with abdominal distention and epigastric discomfort for two years. Preoperatively villous adenoma with suspicious cancerous changes in the ascending colon was suspected and a right hemicolectomy was performed. Grossly, a tongue-like projection of the enlarged ileocecal valve up to 3*1.5cm was featured microscopically with heavy deposition of mature fat tissue in the subucosal layer. Case 2 was a 33-year-old female with an episode of melena. After radiologic and endoscopic study for Behcets enterocolitis, the right hemicolectomy was performed. Grossly, the ileocecal valve was enlarged up to 3cm and the histologic feature was similar to that of the first case. Through these two cases, we made the conclusion that an appropriate understanding of ileocecal valvular hyperplasia seems to be the first step to make a preoperative histologic diagnosis and prevent oversurgery.

TTP가 병발한 SLE에서 조기에 신선 냉동 혈장 투여와 혈장 교환술을 적극적으로 시행해야 한다. 이러한 적극적인 초기 치료에도 불구하고 병이 진행하거나, 루푸스 신염이 동반된 경우에 cyclophosphamide의 병합 요법이 치료에 도움이 됨을 저자들은 경험하여 보고하는 바이다. Thrombotic thrombocytopenic purpura is a rare but fatal complication of systemic lupus erythematosus. The diagnosis of thrombotic thrombocytopenic purpura as a syndrome distinct from systemic lupus erythematosus may be challenging particularly when thrombotic thrombocytopenic purpura is presented concomitantly with systemic lupus erythematosus. Early diagnosis and aggressive treatment including plasmapheresis would be required. However, recent reports have suggested that the use of cyclophosphamide may have a role. We describe a patient with systemic lupus erythematosus who was first presented with severe thrombotic thrombocytopenic purpura. Diagnosis was based on typical clinical features of thrombotic thrombocytopenic purpura and laboratory findings of active lupus nephritis. Renal biopsy also confirmed the coexistence of thrombotic thrombocytopenic purpura and diffuse proliferative lupus nephritis. Although prompt extensive plasmapheresis and high dose steroid therapy were performed, oliguric renal failure and thrombocytopenia persisted. After addition of cyclophosphamide to the treatment with plasmapheresis and steroid, clinical manifestations of thrombotic thrombocytopenic purpura and lupus nephritis were markedly improved.

We report a case of adult-onset tubulointerstitial nephritis and uveitis syndrome with Fanconi syndrome. A 31-year-woman presented with fever, anorexia, nausea, general weakness and weight loss for two months. Her initial laboratory findings showed anemia, high serum creatinine, hypouricemia, hypophosphatemia, hypokalemia, glucosuria, and proteinuria. She was diagnosed as having acute tubulointerstitial nephritis by renal biopsy. The etiology of tubulointerstitial nephritis was unclear. She was treated with systemic corticosteroid. Six months later and while the patient was still on systemic corticosteroid (Deflazacort 36 mg), bilateral uveitis developed. Renal function was recovered by systemic corticosteroid and mycophenolic acid. But ocular symptoms relapsed twice despite systemic corticosteroid treatment. The ocular symptoms improved after topical ophthalmic steroid drops and injection. Tubulointerstitial nephritis and uveitis syndrome should be considered in the differential diagnosis of the unexplained tubulointerstitial nephritis. And the need of the steroid treatment also should be considered in the case of adult-onset.
