Liver Cyst Infection after Colon Endoscopic Mucosal Resection in a Patient with Autosomal Dominant Polycystic Kidney Disease on Maintenance Hemodialysis.

A 60-year-old Japanese man with autosomal dominant polycystic kidney disease (ADPKD) on maintenance hemodialysis underwent colonoscopy and endoscopic mucosal resection (EMR). He was hospitalized after 4 days of fever that began the day following colonoscopy. We detected Klebsiella pneumoniae in a blood culture and a ring-shaped integration in the liver cyst by gallium scintigraphy. He recovered with antibiotics and percutaneous drainage. The patient was believed to have contracted the liver cyst infection via an injured colonic mucosa and portal vein. Thus, if a patient exhibits fever after a colon EMR, for patients with ADPKD, then a liver cyst infection should also be considered in the differential diagnosis.

[A Case of Advanced Transverse Colon Cancer with Nephrotic Syndrome Treated with Curative Resection and Complete Adjuvant Chemotherapy].

A 74-year-old woman was diagnosed as having transverse colon cancer after diagnosis of nephrotic syndrome caused by membranous nephropathy. Although she had hypoproteinemia and hypoalbuminemia, we judged that she had no major nutritional problem. In previous, similar case reports, the use of human serum albumin and fresh-frozen plasma was suggested to be important to avoid complications in the perioperative period. Thus, we used the same in our patient in the perioperative period. In addition, we paid special attention to perioperative nutrition management and used total parenteral nutrition in perioperative period. We performed laparoscopic assisted right hemicolectomy. On the 15th day after the surgical resection, the patient was discharged without any problems. We considered that postoperative adjuvant chemotherapy with XELOX (CapeOX)should be performed because the TNM pathological stage was pStage III b. Regarding adjuvant chemotherapy for gastrointestinal cancer with nephrotic syndrome, no previous reports detailed the indications for postoperative adjuvant chemotherapy. Upon introduction of adjuvant chemotherapy, we determined adaptation in accordance with the general adaptation criteria. While observing the patient's progress with a nephrologist, we safely completed the scheduled 8 courses adjuvant chemotherapy.

Remitting seronegative symmetrical synovitis with pitting edema syndrome in a chronic hemodialysis patient.

A 75-year-old male who was undergoing chronic hemodialysis developed abrupt-onset pitting edema and pain in the dorsum of both hands and feet. Biochemical analysis disclosed increased C-reactive protein, and negative rheumatoid factor and antinuclear antibody. Radiological examination showed no bony erosion. Computed tomography and gallium scintigraphy revealed no active infection or neoplasms. The clinical diagnosis was remitting seronegative symmetrical synovitis with pitting edema (RS(3)PE) syndrome. The pitting edema and inflammatory response quickly subsided after low-dose prednisolone therapy. This case demonstrates that RS(3)PE syndrome could be a differential diagnosis in elderly patients undergoing dialysis who develop pitting edema and joint pain.
