Review Case Reports
Sellar solitary plasmacytoma progressing to multiple myeloma: a case report and literature review.
Sellar plasmacytoma is a rare cause of sellar lesions. Preoperative diagnosis remains a challenge. We present a 34-year-old Chinese woman with a 25-day history of headache and diplopia. ⋯ The operation was cancelled and further studies confirmed the diagnosis of sellar solitary plasmacytoma that progressed to multiple myeloma. After undergoing radiotherapy, high-dose chemotherapy, and autologous peripheral blood stem cell transplantation, complete remission was achieved on 4 years follow-up. We reviewed the pertinent literature and reached the following conclusions: sellar plasmacytomas with development of multiple myeloma on follow-up more likely happened in men than in women; and if the sellar plasmacytoma does not compress the cranial nerve, transsphenoidal resection should be cautious because the systemic treatment with radiotherapy, chemotherapy, and autologous peripheral blood stem cell transplantation may be more effective with little invasion.

Hyperammonemia has been reported to be associated with patients who receive valproic acid (VPA) therapy. This study aimed to determine the risk factors for hyperammonemia in patients with epilepsy treated with VPA. One hundred and fifty-eight adult patients with epilepsy aged older than 17 years who received VPA therapy were enrolled into this study. ⋯ In conclusion, the use of VPA in adult patients with epilepsy was associated with a dose-dependent increase in blood concentrations of ammonia. Combination treatment with liver enzyme-inducing AEDs and antipsychotic drugs increased the risk of VPA-induced hyperammonemia. Most of the patients with VPA-induced hyperammonemia were asymptomatic; however, if patients taking VPA present with symptoms such as nausea, fatigue, somnolence, ataxia, and consciousness disturbance, the blood ammonia level should be measured.

Acute renal failure (ARF) is a common complication in infants who undergo cardiac surgery in the intensive care unit. We report on a modified drainage catheter used in peritoneal dialysis (PD) for the treatment of ARF associated with cardiac surgery in infants. Thirty-nine infants with congenital heart disease undergoing cardiac surgery who developed ARF at our center between January 2009 and January 2012 were assessed. ⋯ These complications were readily treated by drugs or resolved spontaneously. Hemodynamics, cardiac function, and renal function improved significantly during PD. These data suggest that PD using a modified drainage catheter for ARF after cardiac surgery in infants is safe, feasible, inexpensive, and yields good results.

Case Reports
A challenging case of rapid progressive Kaposi sarcoma after renal transplantation: diagnostics by FDG PET/CT.
De-novo malignancy is a serious posttransplant complication. While the incidence of Kaposi sarcoma (KS) is low, the time for its diagnosis is early after renal transplantation. ⋯ This striking case illustrates the usefulness of [18F]2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography for demonstrating the cause of unexplained deterioration of patient's condition. Early identification of KS is critical because early (modification of) therapy can substantially improve patient's prognosis.

Peritoneal metastasis is the most frequent cause of death in patients with gastric cancer. Reverse transcriptase-polymerase chain reaction (RT-PCR) assay of peritoneal washes has been used to predict peritoneal metastasis of gastric carcinoma. We applied carcinoembryonic antigen (CEA) and melanoma-associated gene (MAGE) RT-PCR for the detection of peritoneal metastasis of gastric carcinoma after curative surgery and evaluated its clinical significance. ⋯ MAGE expression was determined to be the most important prognostic factor for recurrence (hazard ratio: 12.487, P < 0.01). It is feasible to identify free cancer cells in peritoneal lavage by using a MAGE A1-A6 and CEA RT-PCR. MAGE RT-PCR results disclosed significant associations with peritoneal recurrence and proved to be the most important factor for the recurrence rate in patients with gastric carcinoma who had undergone radical resection.
