Complicated malaria is mainly caused by Plasmodium falciparum, but, increasingly, Plasmodium vivax is also being reported as a cause. Since the reemergence of indigenous vivax malaria in 1993, cases of severe malaria have been steadily reported in Korea. Herein, we report a case of vivax malaria complicated by adult respiratory distress syndrome (ARDS) that was successfully managed with extracorporeal membrane oxygenation (ECMO). A 59-year-old man presented at our hospital with fever and abdominal pain, which had persisted for 10 days. On admission, the patient had impaired consciousness, shock, hypoxia and haziness in both lungs, jaundice, thrombocytopenia and disseminated intravascular coagulation, metabolic acidosis, and acute kidney injury. A peripheral blood smear and a rapid diagnostic test verified P. vivax mono-infection. Ten hours after admission, hypoxia became more severe, despite providing maximal ventilatory support. The administration of antimalarial agents, ECMO, and continuous venovenous hemofiltration resulted in an improvement of his vital signs and laboratory findings. He was discharged from the hospital 7 weeks later, without any sequelae.

PURPOSE: The frequency of diagnosis of each nodule category under the Bethesda classification was studied, and the differences in the results between cytopathologic and histopathologic analyses of same patients were assessed. Special attention was paid to the atypical cells of undetermined significance (ACUS), which is an intermediate category. The histopathology of ACUS specimens was confirmed to examine the clinical implication. METHODS: Patients (n=417) who underwent thyroid ultrasonography and fine needle aspiration of the thyroid since the application of Bethesda classification (November 2009 to August 2010) in this institution was enrolled in the study. RESULTS: According to the Bethesda criteria, of the 640 nodules there were 56 cases (8.8%) of ACUS, 14 cases (2.2%) of follicular neoplasm, 13 cases (2.0%) were suspicious for malignancy, and 37 cases (5.8%) were positive of malignancy. A total of 102 surgically-excised specimens were obtained, of which 40 specimens were previously categorized cytopathologically as ACUS. Of these 40 specimens, 16 cases (40%) were found to be malignant. CONCLUSION: A precise understanding of each diagnostic category seems to be necessary, which may help with treatment of patients with thyroid mass. This is especially true for ACUS, which was previously understood as an intermediate specimen, but which is actually a heterogeneous mix of benign specimen, benign specimen with various atypia, and malignancy. In case of ACUS, an extensive and accurate diagnostic approach utilizing various examination methods may be beneficial for the patient treatment.
