BACKGROUND: We analyzed the clinical characteristics of trauma involving the liver and/or the spleen to evaluate the safety of nonoperative management. METHODS: A retrospective study was conducted on 78 cases who were treated with operative (37 cases) and nonoperative (41 cases) management at Wonkwang University Hospital from January 1995 to June 1998. Nonoperative management was done in hemodynamically stable patients. RESULTS: Three cases in the operative group (OG) and 5 cases in the nonoperative group (NOG) were children. Causes of injury were traffic accidents (66.6%), falls (15.4%), penetrating injuries (11.4%), and assaults (6.4%). Associated intraabdominal injuries were renal contusions (42%), pancreatic injuries (18%), mesenteric tearing (12%), diaphragm ruptures (9%). Associated extraabdominal injuries were chest injuries (56.5%), long bone fractures (15.2%), pelvic bone fractures (9.8%), and CNS injuries (8.7%). Mean total blood requirements were 7.0 units in the OG and 1.2 units in the NOG. Complications were 35 cases in the OG (pleural effusion, 6 cases; intraabdominal abscess, 4 cases; pneumonia, 4 cases; biloma, 3 cases) and 15 cases in the NOG (pleural effusion, 5 cases; pneumonia, 5 cases; intraabdominal abscess, 2 cases). Causes of 8 delayed operations were bowel perforations (small bowel 2 cases, and colon, 1 case), bile peritonitis (2 cases), and hemodynamically instability (3 cases). The hospitalization period was 16 days in the OG and 14 days in the NOG. Six patients in the OG died and the causes were multiple organ failures (4 cases), hypovolemic shock (1 case), and ARDS (1 case). No patient died in the delayed operation cases and the NOG, even in major injury cases aquired respiratory distress syndrom. CONCLUSIONS: Nonoperative management of traumatic liver and/or spleen injury is safe and can be tried initially under the conditions of stable hemodynamics, feasible abdominal CT, and feasible immediate operation.

Aortic saddle embolus accounts for approximately 10% of all peripheral arterial emboli. The most common sources of emboli are left atrial thrombi associated with atrial fibrillation and vegetation. A 22-year-old male patient was admitted due to acute onset of orthopnea, tachypea and cough. Transthoracic and transeophageal echocardiography showed huge vegetation (3X2cm) of the posterior mitral valve leaflet which was associated with severe mitral regurgitation. On 14th hospital day, he suffered from sudden onset of weakness, pain, and coldness on both lower extremities. Follow-up echocardiography showed marked size reduction of the original mitral valve vegetation. Angiography showed aortic saddle embolus. The embolectomy of aortic saddle embolus was performed through the transfemoral approach with a Forgarty catheter. At the same time, removal of the infected mitral valve and mitral valve replacement were performed.

PURPOSE: The objective of this study was to investigate whether proton magnetic resonance spectroscopy (1H-MRS) is useful in the prediction of the neurological outcome for comatose patients after successful cardiopumonary resuscitation (CPR). METHODS: We prospectively studied 22 patients with a comatose mentality existing for longer than 1 day after cardiac arrest. 1H-MRS examinations were scheduled to be performed within 5 days after restoration of spontaneous circulation (ROSC). All 1H-MRS readings were performed by a neuro-radiologist blindly. The best cerebral performance category (CPC) during 6 months after ROSC was used as the final outcome and classified as good (CPC 1-2) or poor (CPC 3-5). RESULTS: Elevated cerebral lactate resonances were found in 14 patients. All of the 14 lactate-positive patients experienced a poor outcome. Five of the 8 lactate-negative patients recovered without neurologic defects, but three of them suffered from severe neurologic defects. The elevated cerebral lactate resonance distinguished between good out-comes (n=5) and poor outcomes (n=17) with three false negatives (sensitivity 82%) and no false positives (specificit y 100%). Demonstration of brain lactate in 1H-MRS (p < 0.05) proved to be significant in terms of a poor prognosis. CONCLUSION: 1H-MRS is of great benefit in the prognostic evaluation of comatose patients with anoxic-ischemic encephalopathy after successful CPR.

Postoperative rhabdomyolysis with acute renal failure (ARF) is a rare complication of laparoscopic urologic surgery. It is associated with lateral decubitus surgical position, long operative time, and increased body mass. We report a case of a 49-year-old-man with right renal cell carcinoma who underwent a laparoscopic right radical nephrectomy for 7 hours in left decubitus position and was complicated by ARF due to postoperative rhabdomyolysis. Laparoscopic renal surgery is performed in many surgical renal diseases and heightened suspicion may help early recognition of postoperative rhabdomyolysis. Vigorous hydration and hemodialysis are also helpful in treating ARF secondary to rhabdomyolysis

OBJECTIVES: Our study examined the dose-response relationship between smoking amounts (pack-years) and the risk of developing pancreatic cancer in Korean men. METHODS: Of 125,743 participants who underwent medical health checkups in 2009, 121,408 were included in the final analysis and observed for the development of pancreatic cancer. We evaluated the associations between smoking amounts and incident pancreatic cancer in 4 groups classified by pack-year amounts. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of incident pancreatic cancer by comparing groups 2 (<20 pack-year smokers), 3 (20-≤40 pack-year smokers), and 4 (>40 pack-year smokers) with group 1 (never smokers). RESULTS: During 527,974.5 person-years of follow-up, 245 incident cases of pancreatic cancer developed between 2009 and 2013. The multivariate-adjusted HRs (95% CIs) for incident pancreatic cancer in groups 2, 3, and 4 were 1.05 (0.76 to 1.45), 1.28 (0.91 to 1.80), and 1.57 (1.00 to 2.46), respectively (p for trend=0.025). The HR (95% CI) of former smokers showed a dose-response relationship in the unadjusted model, but did not show a statistically significant association in the multivariate-adjusted model. The HR (95% CI) of current smokers showed a dose-response relationship in both the unadjusted (p for trend=0.020) and multivariate-adjusted models (p for trend=0.050). CONCLUSIONS The risk of developing pancreatic cancer was higher in current smokers status than in former smokers among Korean men, indicating that smoking cessation may have a protective effect.

Abiotrophia defectiva, a nutritionally variant streptococci can cause bacteremia, brain abscess, septic arthritis and in rare cases, infective endocarditis, which accounts for 5-6% of all cases. A. defectiva is characteristically difficult to diagnose and the mortality, morbidity and complication rates are high. Here, we discuss a case of infective endocarditis caused by A. defectiva. A 62-year-old female had previously undergone prosthetic valve replacement 6 years prior to admission. She developed infective endocarditis after tooth extraction. Her endocarditis was successfully treated with antimicrobial therapy and mitral valve replacement surgery. This is the first case of infective endocarditis caused by A. defectiva reported in Korea. This case shows that A. defectiva could be considered as a causative organism of infective endocarditis in Korea.

BACKGROUND: The differences in clinical features are important when differentiating between Alzheimer's disease (AD) and vascular dementia (VD). There have been many studies comparing the severity of progression in both diseases. They have assessed individual symptoms but have not explained the differences and global change of progression comprehensively. We have evaluated the cognitive and non-cognitive functions at the same time and evaluated the differences between AD and VD. METHODS: One hundred and thirty-eight dementia patients from Busan?Gyeongnam Dementia Association outpatient clinics were analyzed. All of the patients underwent the Korean version of the Mini-Mental State Examination (K-MMSE), the expanded version of the Korean Clinical Dementia Rating Scale (CDR), the Korean version of the Neuropsychiatric Inventory (K-NPI), the scales for activity of daily living, and the Short form of the Samsung Dementia Questionnaire (S-SDQ). RESULTS: There were 93 patients with AD and 45 with VD. VD patients revealed more severe Barthel Index of Activity of Daily Living (B-ADL) deficits. AD patients had more severe memory and orientation deficiency in CDR 1 and CDR 2. VD patients revealed much faster decline of K-MMSE score between CDR 2 and CDR 3. CONCLUSIONS: These results suggest that VD patients display more severe B-ADL difficulty, while AD patients display more severe memory difficulty and disorientation. B-ADL progresses in the earlier stages in VD and in the later stages in AD. Global cognitive dysfunction progression is the opposite: in the earlier stages in AD and in the later stages in VD.

BACKGROUND: Behavioral and psychological symptoms (BPSD) are common in dementia. These may be helpful for clinical differentiation between Alzheimer's disease (AD) and vascular dementia (VD). Most previous studies have reported the prevalence and severity of BPSD regardless of severity of progression. However, we evaluated the differences of BPSD by grading dementia progression and including severe cases only. METHODS: 141 dementia outpatients from clinics of Busan-Gyeongnam Dementia Association in Korea were analyzed. All patients were administered the Korean version of the Neuropsychiatric Inventory (K-NPI), the expanded version of Korean Clinical Dementia Rating Scale (CDR), and the Korean version of Mini-Mental State Examination (K-MMSE). RESULTS: There were 95 patients with AD and 46 patients with VD. AD patients revealed higher frequency of manifested BPSD symptoms and most of subscales showed higher composite scores also. But apathy was more severely and frequently manifested in VD. AD patients had more frequent night-time behavior and aberrant motor symptoms above 3 point in CDR 0.5 and VD patients had more frequent apathy symptom above 3 point in CDR 1. CONCLUSIONS: These results suggest that generally AD patients revealed more frequent and severe BPSDs than VD patients. Apathy was a more dominant symptom in VD. It seemed that some of the symptoms were valuable clues for the differential diagnosis even though a better designed study was required.

PURPOSE: The higher prevalence of respiratory allergic disease may be due to increased exposure to inhalation allergens. We conducted a survey of allergic diseases in autumn and winter with detection of major indoor allergens in major cities in Korea. METHODS: We enrolled 110 subjects from the fourth Korea National Health and Nutrition Examination Survey with stratified, cluster, and systematic sampling procedures. All participants answered a health questionnaire as well as underwent a skin prick test (SPT) and ImmunoCAP for 11 indoor major allergens. We also measured the levels of 5 major allergens (Der f 1, Der p 1, Can f 1, Bla g 1, and Asp f 1) in fine indoor dust from the houses of 60 subjects with a 2-site ELISA. RESULTS: The prevalence of allergic rhinitis and asthma were 25.5% and 7.3%, respectively. The most common sensitized allergens identified by SPT and ImmunoCAP were Dermatophagoides farinae (40.9%, 36.8%), followed by cockroach (23.6%, 19.5%), mugwort (13.6%, 22.9%), oak (9.1%, 22.9%), Japanese hop (9.1%, 8.6%), and dog dander (8.2%, 6.9%). There was a modest discrepancy between SPT and ImmunoCAP. Der f 1 and Der p 1 were detected in 91.7% and 45.0% of the enrolled houses, respectively. Der f 1 indicated high concentrations in all specific provinces in Korea; however, Der p 1 measured high only in the south. Dog dander allergens were present in 71.7% of houses; however, Bla g 1 was present in only 11.7% of houses and Asp f 1 was not detected in any houses. CONCLUSIONS: The most important inhalant allergens in Korea are house dust mites followed by cockroach, mugwort, oak, Japanese hop, and dog dander in indoor environment, in which The dominant species of house dust mites were different according to region.

The incidence of Clostridium difficile infection is increasing worldwide, and its severity and resulting mortality are also on the rise. Metronidazole and oral vancomycin remain the treatments of choice, but there are concerns about treatment failure and the appearance of resistant strains. Furthermore, antibiotic therapy results in recurrence rates of at least 20%. Fecal transplantation may be a feasible treatment option for recurrent C. difficile infection; moreover, it may be an early treatment option for severe C. difficile infection. We report a case of severe C. difficile infection treated with fecal transplantation using a nasoenteric tube during an initial episode. This is the first reported case of fecal transplantation using a nasoenteric tube during an initial episode of C. difficile infection in Korea.
