Two Cases of Early Onset Acute Buried Bumper Syndrome after Percutaneous Endoscopic Gastrostomy

Buried bumper syndrome (BBS) is an unusual complication of percutaneous endoscopic gastrostomy (PEG) tube placement, typically occurring 3-6 months thereafter. Few documented cases exist of BBS occurring within 14 days of PEG tube insertion (termed early onset BBS). Information regarding the clinical features and appropriate management of early onset BBS is limited. Herein we report our experience of two cases of early onset BBS successfully treated endoscopically, together with the literature review.

Clinically Useful Diagnostic Tool of Contrast Enhanced Ultrasonography for Focal Liver Masses: Comparison to Computed Tomography and Magnetic Resonance Imaging

BACKGROUND/AIMS: To evaluate the diagnostic value of contrast (SonoVue(R)) enhancement ultrasonography (CEUS) and to compare this method with computed tomography (CT) and magnetic resonance imaging (MRI) in evaluating liver masses. METHODS: CEUS (n=50), CT (n=47), and MRI (n=43) were performed on 50 liver masses in 48 patients for baseline mass characterization. The most likely impression for each modality and the final diagnosis, based on the combined biopsy results (n=14), angiography findings (n=36), and clinical course, were determined. The diagnostic value of CEUS was compared to those of CT and MRI. RESULTS: The final diagnosis of the masses was hepatocellular carcinoma (n=43), hemangioma (n=3), benign adenoma (n=2), eosinophilic abscess (n=1), and liver metastasis (n=1). The overall diagnostic agreement with the final diagnosis was substantial for CEUS, CT, and MRI, with kappa values of 0.621, 0.763, and 0.784, respectively. The sensitivity, specificity, and accuracy were 83.3%, 87.5%, and 84.0%, respectively, for CEUS; 95.0%, 87.5%, and 93.8%, respectively, for CT; and 94.6%, 83.3%, and 93.0%, respectively for MRI. After excluding the lesions with poor acoustic sonographic windows, the sensitivity, specificity, and accuracy for CEUS were 94.6%, 87.5%, and 93.3%, respectively, with a kappa value of 0.765. CONCLUSIONS: If an appropriate acoustic window is available, CEUS is comparable to CT and MRI for the diagnosis of liver masses.

A Case of Rectus Sheath Hematoma and Pelvic Cavity Hematoma Induced by Dalteparin Injection / 대한내과학회지

Rectus sheath hematoma (RSH) is an uncommon condition caused by hemorrhage into the rectus sheath. RSH is characterized by abdominal pain and an abdominal mass. This condition is associated with old age, childbirth, abdominal surgery, severe coughing, severe sneezing, anticoagulation therapy, and/or coagulation disorders. We report herein a case of RSH and pelvic cavity hematoma that was induced by dalteparin injection in a 77-year-old woman with pulmonary embolism and deep vein thrombosis, and who was successfully treated by conservative management.

Bortezomib Induced Tumor Lysis Syndrome in Multiple Myeloma

The tumor lysis syndrome (TLS) commonly occurs in the lymphoproliferative disorder, either spontaneously or in response to therapy. TLS is uncommon in multiple myeloma. However, with the use of bortezomib in the treatment of multiple myeloma, cases of TLS have been reported. We report here threepatients who presented with TLS after the administration of bortezomib. Two of them presented mild symptoms and recovered with hydration only. However, death of the other patient was associated with TLS. We should monitor patients who had high tumor burden, especially in early phase of bortezomib therapy and appropriate prophylaxis for high risk patient is also needed.
