Cardiac rupture following blunt thoracic trauma is rarely encountered, since it commonly causes death at the scene. With advances in critical care, blunt cardiac rupture has been successfully treated with well-organized team approach including an emergency physician, anesthesiologist, and cardiac surgeon. We encountered a patient with blunt cardiac rupture of the junction of the superior vena cava and right atrium that extended 7 cm to the right ventricular junction. The patient was successfully resuscitated after a closed thoracostomy and pericardiocentesis with fluid loading. Cardiac injury was repaired via mid-sternotomy without cardiopulmonary bypass. The patient recovered without complications and was discharged on the 7th day after surgery.

BACKGROUND: Totally implantable access port (TIAP) provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. METHODS: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92) and subclavian approach (Group 2, n = 79) between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. RESULTS: Median follow-up for TIAP was 278 days (range, 1-1868). Twenty four complications were occurred (14.0%), including pneumothorax (n = 1, 0.6%), migration/malposition (n = 4, 2.3%), pinch-off syndrome (n = 4, 2.3%), malfunction (n = 2, 1.1%), infection (n = 8, 4.7%), and venous thrombosis (n = 5, 2.9%). The overall incidence was 8.7% and 20.3% in each group (p = 0.030). Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033). The mechanical complication free probability is significantly higher in group 1 (p = 0.040). CONCLUSIONS: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterist of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionnaire. They are belong to 5 departments of the factory-the Engine-Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration; Of all measured points(52), 9 points(17.2%) exceeded 5mg/m3-the time-weighed PEL- and one department had a upper confidence limit(95%) higher than 5mg/m3. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time-itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne(2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation(1, 0.6%), and non-specific hand eczema(47, 29.3%). 4) The prevalence of any skin diseases was 34.0 per 100 in cutting oil users, and 13.3 per 100 in non-users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 4.3 per 100 in non-users. 5) We tried patch test(standard series, oil series, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independent=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).

We report the first case of ocular benign lymphoid hyperplasia (BLH) treated with subconjunctival injection of bevacizumab (Avastin). A 27-year-old man presented to our clinic with conjunctival masses and limbal neovascularization. An incisional biopsy yielded the diagnosis of BLH. The patient was subsequently given a subconjunctival injection of bevacizumab (1.25 mg / 0.1 mL). The patient did not experience recurrence or malignant metaplasia during the one-year follow-up period. In patients with conjunctival BLH, subconjunctival injection of bevacizumab can be a useful treatment option in patients unable to undergo a surgical procedure due to limbal neovascularization.

Although there are still controversies about whether hypertriglyceridemia is an independent risk factor for coronary artery disease, recent analysis reported hypertriglyceridemia and central obesity are independent risk factors for coronary artery disease. However, the prognostic impact of hypertriglyceridemia and central obesity in acute myocardial infarction (AMI) patients underwent percutaneous coronary intervention (PCI) are still remained unclear. In this issue, Han et al. investigated the prognostic impact of hypertriglyceridemia and/or central obesity on baseline in AMI patients treated with PCI. In this editorial, we have reviewed the role of hypertriglyceridemia and central obesity on the prognosis after PCI in AMI patients. Although hypertriglyceridemia and central obesity on baseline in this study had no role on the prognosis following PCI in AMI patients, to confirm for these results, further studies on this topic will be warranted in the future.

BACKGROUND: As preoperative diagnosis of acute appendicitis is sometimes difficult, various diagnostic modalities are used for accurate diagnosis. The aims of this study were to define the diagnostic parameters of ultrasonographic (USG) examination and to evaluate the diagnostic efficacy of clinical scoring system in the patients with suspected acute appendicitis. METHODS: A consecutive 130 patients, admitted under impression of acute appendicitis, were underwent routine ultrasonographic examination (from December 1994 to July 1995), and analyzed the accuracy rate of ultrasonographic examination. Already applied diagnostic score (age> or =50 yrs; 1.5, steady pain in right low quadrant; 2, pain relocation to RLQ; 2, tenderness in RLQ; 2.5, rebound tenderness; 2.5, rigidity; 1, Rovsing sign; 2, Rosenstein sign; 2, and leukocyte> or =10,000/mm3; 1.5) in these same patients also analyzed for correlation with final diagnosis and ultrasonographic examination retrospectively. In the second prospective study (from August 1995 to December 1995), 102 patients were enrolled, and diagnostic scoring system was evaluated for the applicability in diagnosis of appendicitis. RESULTS: Of ninety-nine operated patients (clinical and sonography suggested appendicitis), 93 patients (94%) were confirmed as a acute appendicitis, and remaining 6 patients (6%) revealed mesenteric lymphadenitis and 31 patients were discharged without operation. Accuracy of the ultrasonographic examination was 91% of sensitivity, 86% of specificity, and 90% of accuracy rate, respectively. Diagnostic score (>10 point) of these patients revealed also a sensitive parameter in diagnosis of acute appendicitis with 94% of sensitivity, 71% of specificity, and 86% of accuracy rate. In the second prospective study, 85 patients (97% of 88 cases) with diagnostic score over 10 points had been confirmed as a acute appendicitis and only two cases (14% of 14 cases) having below 10 points in diagnostic score needed appendectomy. Over 10 ponits of diagnostic score in diagnosis of appendicitis revealed 98% of sensitivity, 80% of specificity, 96.5% of positive predict value, 85.7% of negative predict value, and 95% of accuracy rate, and relative risk 4.89 (p=0.000). Using multivariate analysis, age (> or =50 years),diagnostic score (> or =10), diameter of appendix (> or =6 mm) in USG, and Rovosing sign were significant independent factors in the diagnosis of acute appendicitis. CONCLUSION: Our results suggest that ultrasonographic examination is necessary in patients with low diagnostic score (<10) to avoid negative laparatomy, but patients with high diagnostic score (>10) can be operated without ultrasonographic examination.
