A Case of Polymicrobial Fungal and Bacterial Spondylodiscitis / 대한내과학회지

A 66-year-old female who had undergone surgery for a herniated disc at the L5-S1 level at another hospital 3 months earlier was admitted with persistent back and leg pain. She was diagnosed with spondylodiscitis at the L5-S1 level by magnetic resonance imaging. A biopsy was performed, and Candida parapsilosis and Enterococcus faecium were isolated from the excised material. We report herein a case of successful treatment of polymicrobial spondylodiscitis in accordance with accurate microbiological diagnosis. Based on this case, we hope to encourage physicians to perform biopsies more aggressively or repeatedly to improve the diagnostic yield.

Comparison of Surgery Plus Chemotherapy and Palliative Chemotherapy Alone for Advanced Gastric Cancer with Krukenberg Tumor / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: This study was conducted to validate the survival benefit of metastasectomy plus chemotherapy over chemotherapy alone for treatment of Krukenberg tumors from gastric cancer and to identify prognostic factors for survival. MATERIALS AND METHODS: Clinical data from 216 patients with Krukenberg tumors from gastric cancer were collected. Patients were divided into two arms according to treatment modality: arm A, metastasectomy plus chemotherapy and arm B, chemotherapy alone. RESULTS: Overall survival (OS) was significantly increased in arm A relative to arm B for patients initially diagnosed with stage IV gastric cancer (18.0 months vs. 8.0 months; p < 0.001) and those with recurrent Krukenberg tumors (19.0 months vs. 9.0 months; p=0.002), respectively. Metastasectomy (hazard ratio [HR], 0.458; 95% confidence interval [CI], 0.287 to 0.732; p=0.001), signet-ring cell pathology (HR, 1.583; 95% CI, 1.057 to 2.371; p=0.026), and peritoneal carcinomatosis (HR, 3.081; 95% CI, 1.610 to 5.895; p=0.001) were significant prognostic factors for survival. CONCLUSION: Metastasectomy plus chemotherapy offers superior OS when compared to palliative chemotherapy alone in gastric cancer with Krukenberg tumor. Prolonged survival applies to all patients, regardless of gastric cancer stage. Metastasectomy, signet-ring cell pathology, and peritoneal carcinomatosis were prognostic factors for survival. Future prospective randomized trials are needed to confirm the optimal treatment strategy for Krukenberg tumors from gastric cancer.

Treatment of a Patient with Kaposi's Sarcoma Arising during Hemodialysis with the Multikinase Inhibitor Pazopanib / 대한내과학회지

Kaposi's sarcoma (KS) is an unusual multifocal neoplastic angioproliferative disorder. We herein report a case of classic KS that occurred in a patient receiving hemodialysis for 7 years. The patient had a history of chronic renal failure due to glomerulonephritis for 20 years. Multiple reddened violaceous patches, plaques, and nodules were found on the right knee. Biopsy revealed positivity for human herpesvirus 8 (KS-associated herpesvirus) consistent with KS. Pazopanib, a multitarget tyrosine kinase inhibitor, is an effective agent for treatment of advanced soft tissue sarcoma. The patient received pazopanib for 6 months investigate its effects on KS. The skin lesions and painful symptoms showed improvement. Further studies are required to determine the mechanism underlying the anticancer action of pazopanib and the pathogenesis of KS.

Esophageal Cancer in Esophageal Diverticula Associated with Achalasia

The simultaneous occurrence of achalasia and esophageal diverticula is rare. Here, we report the case of a 68-year-old man with multiple esophageal diverticula associated with achalasia who was later diagnosed with early esophageal cancer. He initially presented with dysphagia and dyspepsia, and injection of botulinum toxin to the lower esophageal sphincter relieved his symptoms. Five years later, however, the patient presented with worsening of symptoms, and esophagogastroduodenoscopy (EGD) was performed. The endoscopic findings showed multifocal lugol-voiding lesions identified as moderate dysplasia. We decided to use photodynamic therapy to treat the multifocal dysplastic lesions. At follow-up EGD 2 months after photodynamic therapy, more lugol-voiding lesions representing a squamous cell carcinoma in situ were found. The patient ultimately underwent surgery for the treatment of recurrent esophageal multifocal neoplasia. After a follow-up period of 3 years, the patient showed a good outcome without symptoms. To manage premalignant lesions such as achalasia with esophageal diverticula, clinicians should be cautious, but have an aggressive approach regarding endoscopic surveillance.

A Case of Continuous Ambulatory Peritonitis Dialysis Peritonitis Due to Stenotrophomonas maltophilia Using Antibiotic Combination / 영남의대학술지

Continuous ambulatory peritoneal dialysis (CAPD) peritonitis is a major complication of peritoneal dialysis (PD) and leads to the discontinuation of PD. Despite its limited pathogenicity, CAPD peritonitis caused by Stenotrophomonas maltophilia (S. maltophilia), an important nosocomial pathogen that is present in nature and is usually associated with plastic indwelling devices. Infection of S. maltophilia is associated with a poor prognosis, including inability to maintain the CAPD catheter, because of its resistance to multiple antibiotics. We report a case of CAPD peritonitis due to S. maltophilia that was treated successfully using oral Trimethoprim-sulfame-thoxazole and intraperitoneal Ticarcillin/clavulanate without removing the dialysis catheter.
