RESUMEN

BACKGROUND/AIMS@#Procalcitonin (PCT) may prove to be a useful marker to exclude or predict bloodstream infection (BSI). However, the ability of PCT levels to differentiate BSI from non-BSI episodes has not been evaluated in nosocomial BSI.@*METHODS@#We retrospectively reviewed the medical records of patients ≥ 18 years of age with suspected BSI that developed more than 48 hours after admission.@*RESULTS@#Of the 785 included patients, 105 (13.4%) had BSI episodes and 680 (86.6%) had non-BSI episodes. The median serum PCT level was elevated in patients with BSI as compared with those without BSI (0.65 ng/mL vs. 0.22 ng/mL, p = 0.001). The optimal PCT cut-off value of BSI was 0.27 ng/mL, with a corresponding sensitivity of 74.6% (95% confidence interval [CI], 66.4% to 81.7%) and a specificity of 56.5% (95% CI, 52.7% to 60.2%). The area under curve of PCT (0.692) was significantly larger than that of C-reactive protein (CRP; 0.526) or white blood cell (WBC) count (0.518). However, at the optimal cut-off value, PCT failed to predict BSI in 28 of 105 cases (26.7%). The PCT level was significantly higher in patients with an eGFR < 60 mL/min/1.73 m² than in those with an eGFR ≥ 60 mL/min/1.73 m² (0.68 vs. 0.17, p = 0.01).@*CONCLUSIONS@#PCT was more useful for predicting nosocomial BSI than CRP or WBC count. However, the diagnostic accuracy of predicting BSI remains inadequate. Thus, PCT is not recommended as a single diagnostic tool to avoid taking blood cultures in the nosocomial setting.

RESUMEN

OBJECTIVES: To assess the current state of anemia evaluation in the elderly over 80 years of age. METHODS: Patients who were more than 80 years old and visited Dongguk University Ilsan Hospital from April 2005 to February 2014 were included. Statistical analysis were assessed using the logistic regression model. RESULTS: Total 548 patients, who had anemia according to WHO criteria, were identified. The median age was 85 years old (range, 82 to 99 years) and median hemoglobin level was 11.0 g/dL (range, 2.7 to 12.9 g/dL). Twenty-eight, 468, and 52 patients were classified as microcytic anemia, normocytic anemia, and macrocytic anemia, respectively. Among them, 397 patients (72.4%) did not undergo proper evaluation for the cause anemia i.e., 8 cases (28.5%) of microcytic anemia, 361 cases (77.1%) of normocytic anemia, and the 28 cases (53.84%) of 52 macrocytic anemia patients. The remaining 151 patients (27.6%) had completed the evaluation, and 24 patients (15.9%) were diagnosed as solid malignancies. In the assessment of iron deficiency anemia, hemoglobin levels, and age had no effect on whether or not to perform esophagogastroduodenoscopy. CONCLUSION: This finding showed that physicians often neglected anemia in individuals over 80 years of age. Though these patients have limited life expectancy, physicians should carefully discriminate the sub-population who will be benefit from adequate evaluation and treatment.

RESUMEN

Hyponatremia is the most common electrolyte abnormality in hospitalized patients and often presents no symptoms. The association between sinus node dysfunction and hyponatremia has rarely been reported. We describe a 77-year-old woman who developed reversible sinus node dysfunction accompanied by pulmonary edema that was associated with hyponatremia.

RESUMEN

Mucosa-associated lymphoid tissue (MALT) lymphoma is found in various organs as extranodal B cell lymphoma. The gastrointestinal tract is the most commonly involved extranodal site in MALT lymphoma. However, primary esophageal MALT lymphoma is very rare. In addition, few cases with metachronous gastric involvement have been reported. A 55-year-old man was diagnosed with MALT lymphoma by surveillance esophagogastroduodenoscopy. A 5 cm esophageal submucosal tumor-like lesion was incidentally revealed by screening esophagogastroduodenoscopy two years prior. Esophagogastroduodenoscopy showed a cylindrically elongated submucosal mass with normal overlying mucosa in the mid esophagus. He underwent surgery to confirm the diagnosis. The pathologic diagnosis was esophageal MALT lymphoma. He was treated with radiation, which achieved complete remission. Esophagogastroduodenoscopy and chest computed tomography were performed every three to six months, with no evidence of recurrence for 18 months. After 21 months, several elevated gastric erosions were found on the great curvature and posterior sides of the midbody and confirmed as MALT lymphoma pathologically. Here we report a case with MALT lymphoma metachronously involving the esophagus and stomach.
