Mixed-species malaria infections are often unrecognized or underestimated. We hereby report the first described case of mixed infection with Plasmodium falciparum and Plasmodium ovale malaria in a returned traveller in Korea. In August 2016, a 25-year-old returned traveller from Cameroon and Democratic Republic of Congo presented with fever. He was diagnosed as P. falciparum malaria and successfully treated with artesunate. And 5 weeks after the completion of treatment, he presented with fever and diagnosed as P. ovale infection. P. ovale infection is a rare cause of malaria and often shows delayed presentation due to its dormant liver stage as hypnozoites. At re-presentation, the immunochromatographic test and microscopic examinations of our patient did not reveal P. ovale, which was only detected via polymerase chain reaction (PCR) assay. This case highlights the importance of considering malaria infection even in persons who have previously received malaria treatment. It also shows the usefulness of PCR testing for diagnosing P. ovale infections, which often present with a low level of parasitaemia.

This nationwide, prospective cohort study evaluated pulmonary function and radiological sequelae according to infection severity in 73 survivors from the 2015 Middle East respiratory syndrome (MERS) outbreak in Korea. Patients with severe pneumonia in MERS-coronavirus infection had more impaired pulmonary function than those with no or mild pneumonia at the 1-year follow-up, which was compatible with the radiological sequelae. Severe pneumonia significantly impairs pulmonary function and makes long radiological sequelae in MERS.

The average life expectancy of human immunodeficiency virus (HIV)-infected patients has improved dramatically following the advent of highly active anti-retroviral therapy. However, this increased life expectancy has led to a greater incidence of non-acquired immune deficiency syndrome related diseases, including cardiovascular diseases and other malignancies. Increased bone fragility is also a significant concern, with the incidence of osteoporosis and osteoporotic fractures 3- and 2-times more likely, respectively, among HIV-infected patients. Bone mineral density screenings for osteoporosis will therefore become more important as the HIV-infected population ages. Here, we describe six cases of osteoporotic fractures in HIV-infected patients in Korea.

Vertebral hemangioma is the most common benign spinal tumor. It is usually asymptomatic and extraosseous extension causing spinal cord compression with neurologic symptoms is rare. Pre-operative angiography and embolization should be done for definite diagnosis and prevention of excessive blood loss during the operation. In author's case, pre-operative angiography was done for diagnosis, but unfortunately embolization procedure was not available. We performed intra-operative vertebroplasty with polymethylmethacrylate(PMMA) for the prevention of excessive blood loss during the operation and the maintenance of postoperative stability.

A total of 120 infants, children, and teenagers, who were admitted to the Department of Pediatrics, Severance Hospital from April 1989 to August 1989, were examined by cross-sectional echocardiography. Right and left atrial and ventricular dimensions and areas were measured in the parasternal, apical, and subcostal views. Dimensions of the inferior caval vein, the pulmonary and the aorta were obtained in the parasternal, suprasternal, and subcostal views. The results were as follows : 1) Statistical analysis showed no difference between boys and girls. 2) For all parameters, a positive linear correlation was found with age, height, weight, and body surface area. The best correlation was with body surface area. 3) The correlation was further improved if the logarithmic values of the measurements and body surface area were considered. 4) Measurements by cross-sectional echocardiography are clinically useful, especially in the study of the right-sided cardiac structures that are difficult to evaluate with M-mode echocardiography, but the problems of reproducibility have to be taken into account.
