Systemic infections due to Fusobacterium may originate in the tonsillar/internal jugular veins or from the abdomen. We encountered a patient who presented with bacteremia, fulminant septic shock, and extensive soft tissue pyogenic infection due to Fusobacterium necrophorum. In addition, there was widespread metastatic colon cancer with the unique finding of pre-mortem co-localization of F. necrophorum and cancer cells at a site distant from the colon. We reviewed the literature of the association of F. necrophorum and colon cancer, and discuss the evidence of how each of these 2 distinct entities may mutually augment the development or progression of the other.

Symptoms of caliceal diverticular stones are commonly associated with pain, recurrent urinary tract infection and hematuria. The aim of this study is to select the proper patient for the application of more successful extracorporeal shock wave lithotripsy(ESWL) as a treatment of caliceal diverticular stone. 16 patients with caliceal diverticular stones were treated with ESWL, and all patients had single caliceal diverticulum. The diagnosis of caliceal diverticulum with stones was made by intraveneous pyelography to all patients. On these intravenous pyelogram, we also classified diverticular type, whether the diverticular neck is connected with urinary tract patently, diverticular site and stone number and size. All patients were followed after ESWL by plain film of the kidneys, ureters and bladder and interviewed. Of all patients 44% was shown stone-free completely, also 83% was rendered symptom-free. All patients whose diverticular neck connected with urinary tract patently on the intraveneous pyelogram became stone- free. Of solitary stone 60% and multiple stones(more than 2) 17% became stone free. All patients rendered stone-free became symptom-free, and of patients with residual stones 44% became symptom-free. The patients with infection before ESWL 75% had residual stones, of these patients 33% had slightly flank pain, and 25% of patients with stones recurred become stone-free. We propose that more successful ESWL for patients with caliceal diverticular stones select satisfactory patients including that the diverticular neck is connected with urinary tract patently, solitary stone and no infection simultaneously.

Background: Heart-lung transplantation (HLT) has provided hope to patients with end-stage lung disease and irreversible heart dysfunction. We reviewed the clinical outcomes of 10 patients who underwent heart-lung transplantation at Asan Medical Center. Methods: Between July 2010 and August 2014, a total of 11 patients underwent HLT at Asan Medical Center. After excluding one patient who underwent concomitant liver transplantation, 10 patients were enrolled in our study. We reviewed the demographics of the donors and the recipients' baseline information, survival rate, cause of death, and postoperative complications. All patients underwent follow-up, with a mean duration of $26.1{\pm}16.7months$. Results: Early death occurred in two patients (20%) due to septic shock. Late death occurred in three patients (38%) due to bronchiolitis obliterans (n=2) and septic shock (n=1), although these patients survived for 22, 28, and 42 months, respectively. The actuarial survival rates at one year, two years, and three years after HLT were 80%, 67%, and 53%, respectively. Conclusion: HLT is a procedure that is rarely performed in Korea, even in medical centers with large heart and lung transplant programs. In order to achieve acceptable clinical outcomes, it is critical to carefully choose the donor and the recipient and to be certain that all aspects of the transplant procedure are planned in advance with the greatest care.

Purpose: study of the mutual influence of the individual anatomical regions damage in patients associated with falls from heights. Methods: 561 medical reports of patients associated with falls from heights admitted to Republican Research Center of Emergency Medicine (RRCEM), in period of 2010-2013 yy, were analyzed retrospectively. Patient's age range was from 15 to 89. Treatment of these patients held in three stages: period of acute disorders of vital functions; relative stabilization period; stabilization of vital functions. The scope and content of medical diagnostic procedures performed on pre-hospital and intensive care stages. The severity of each injury was scored according to the AIS scale, the total severity of lesions was scored by points due to ISS. Digital material is treated by methods of mathematical statistics. Results: Falls from heights leads to associated injuries for 4 times more than isolated trauma, and increases according to height of fall and falling surface. Patients with TBI+chest trauma, are most serious contingent that has highest mortality and complications (36.8%). TBI+musculoskeletal system trauma are characterized by high blood loss, traumatic shock and fat embolism, forming a vicious circle. Conclusion: in patients associated with falls from heights clinical manifestations of injuries mutual aggravation syndrome will be seen. TBI leads to complication of chest trauma, delayed diagnostics of abdominal and chest trauma, aggravation of coma condition. Developing of high blood loss and fat embolism in musculoskeletal system trauma leads to shock and pulmonary embolism, which increases probability of death in the presence of abdominal or chest trauma, but abdominal trauma or chest trauma has no significant effect on the severity of the musculoskeletal system trauma.

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.

A 61-year-old man presented with chest pain and ST elevation, and he underwent coronary angiography under the impression of acute myocardial infarction. Coronary intervention under intra-aortic balloon pumping was necessary due to his hemodynamic instability from the acute total occlusion of a large obtuse marginal branch. In spite of successful intervention, the cardiogenic shock persisted, and so extracoporeal membranous oxygenation was performed to treat this. Afterwards, the cardiogenic shock still persisted, and the auscultatory and echocardiographic findings revealed severe acute mitral valve regurgitation. Emergency mitral valve replacement was then performed. The ECMO and IABP were removed on the $2^{nd}$ postoperative day. The patient was discharged on the $48^{th}$ postoperative day.

Purpose: The present study was performed to clarify the relationship between periodontal disease severity and selected immunological parameters consisting of serum IgG titer against periodontopathogenic bacteria, the expression of the helper T-cell cytokine by gingival mononuclear cells, and patients' immunoreactivity to cross-reactive heat shock protein (HSP) epitope peptide from P. gingivalis HSP60. Methods: Twenty-five patients with moderate periodontitis had their gingival connective tissue harvested of gingival mononuclear cells during an open flap debridement procedure and peripheral blood was drawn by venipuncture to collect serum. The mean level of interproximal alveolar bone was calculated to be used as an index for periodontal disease severity for a given patient. Each of selected immunologic parameters was subject to statistical management to seek their correlations with the severity of periodontal disease. Results: A significant correlation could not be identified between serum IgG titers against specific bacteria (Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Actinobacillus actinomycetemcomitans, and Streptococcus mutans) and the severity of periodontal disease. Expression of interleukin (IL)-10 by gingival mononuclear cells was statistically significant in the group of patients who had higher levels of alveolar bone height. However, a similar correlation could not be demonstrated in cases for IL-4 or interferon-$\gamma$. Patients' serum reactivity to cross-reactive epitope peptide showed a significant correlation with the amount of alveolar bone. Conclusions: It was concluded that expression of IL-10 by gingival mononuclear cells and patients' sero-reactivity to the cross-reactive HSP peptide of P. gingivalis HSP60 were significantly correlated with alveolar bone height.

Hantavirus pulmonary syndrome(HPS) is a systemic disease that is caused by a newly discorved and characterized virus of the Hantavirus genus, which is most frequently referred to as the sin nombre virus. The clinical syndrome resembles other hantavirus syndromes worldwide, except that it is characterized by a brief prodromal illness followed by rapidly progressive, noncardiogenic edema, and that it is more deadly than any previously recognized hantavirus infection. The clinical manifestations of HPS are characterized by four clinical phases : prodrome, pulmonary edema and shock, diuresis, and convalescence. Mortality is greatest in the first 24 hours of the pulmonary edema and shock phase of the illness. These phases are strikingly similar to the clinical phases of Hemorrhagic fever with renal syndrome(HFRS) induced by Hantaan virus, except that HPS has not been associated with renal failure and Disseminated intravascular coagulation(DIC). We here report a case of hantavirus pulmonary syndrome developed in a 58 year-old man. He had a flu-like illness followed by the rapid onset of respiratory failure due to noncardiogenic pulmonary edema. HPS was diagnosed by clinical manifestations, identification of high titer antibody to Hantaan virus antigen and histologic finding of transbronchial lung biopsy (TBLB) specimen. The patient was treated with mechanical ventilation and initial corticosteroid pulse therapy resulting in successful outcome.

Background: Extracorporeal membrane oxygenation (ECMO) can be used in patients with refractory cardiogenic shock or respiratory failure. In South Korea, the need for transporting ECMO patients is increasing. Nonetheless, information on urgent transportation and its outcomes is scant. Methods: In this retrospective review of 5 years of experience in ECMO transportation at a single center, the clinical outcomes of transported patients were compared with those of in-hospital patients. The effects of transportation and the relationship between insertion-departure time and survival were also analyzed. Results: There were 323 cases of in-hospital ECMO (in-hospital group) and 29 cases transferred to Hallym University Sacred Heart Hospital without adverse events (mobile group). The median transportation time was 95 minutes (interquartile range [IQR], 36.5-119.5 minutes), whereas the median transportation distance was 115 km (IQR, 15-115 km). Transportation itself was not an independent risk factor for 28-day mortality (odds ratio [OR], 0.818; IQR, 0.381-1.755; p=0.605), long-term mortality (OR, 1.099; IQR, 0.680-1.777; p=0.700), and failure of ECMO weaning (OR, 1.003; IQR, 0.467-2.152; p=0.995) or survival to discharge (OR, 0.732; IQR, 0.337-1.586; p=0.429). After adjustment for covariates, no significant difference in the ECMO insertion-departure time was found between the survival and mortality groups (p=0.435). Conclusion: The outcomes of urgent transportation, with active involvement of the ECMO center before ECMO insertion and adherence to the transport protocol, were comparable to those of in-hospital ECMO patients.
