Cardiobacterium hominis, a fastidious gram-negative bacillus rarely causing endocarditis, was isolated from blood culture of a 41-year-old man with subacute bacterial endocarditis. The patient had undergone an operation of valve replacement 4 years before. Growth of the organism was only detected in 1 of 6 blood cultures after 7 days incubation. The isolate showed typical characteristics of C. hominis, i.e., tear-drop like cells and a weak positive indole reaction. The isolate was susceptible to many antimicrobial agents, but penicillin G and streptomycin therapy failed to cure the disease.

The Alstrom syndrome is inherited autosomal recessive disorder, characterized by obesity, diabetes mellitus, pigmentary retinal degeneration, normal intelligence, sensorineural hearing loss, baldness, acanthosis nigricans, male hypogonadism, hyperuricemia and hypertriglyceridemia. There is no reported case of Alstrom syndrome in Korea yet. We experienced a 29-year-old female patient with clinical characteristics similar to Alstrom syndrome who was admitted due to poorly controlled diabetes mellitus and diabetic retinopathy with hemorrhage. We report this case with the review of literatures.

Objective:
To investigate the prognostic value of preoperative cardiac magnetic resonance imaging (MRI) for long-term major adverse cardiac and cerebrovascular events (MACCEs) in patients undergoing tricuspid valve (TV) surgery for functional tricuspid regurgitation (TR).
Materials and Methods:
The preoperative cardiac MR images, New York Heart Association functional class, comorbidities, and clinical events of 78 patients (median [interquartile range], 59 [51–66.3] years, 28.2% male) who underwent TV surgery for functional TR were comprehensively reviewed. Cox proportional hazards analyses were performed to assess the associations of clinical and imaging parameters with MACCEs and all-cause mortality.
Results:
For the median follow-up duration of 5.4 years (interquartile range, 1.2–6.6), MACCEs and all-cause mortality were 51.3% and 23.1%, respectively. The right ventricular (RV) end-systolic volume index (ESVI) and the systolic RV mass index (RVMI) were higher in patients with MACCEs than those without them (77 vs. 68 mL/m2 , p = 0.048; 23.5 vs. 18.0%, p = 0.011, respectively). A high RV ESVI was associated with all-cause mortality (hazard ratio [HR] per value of 10 higher ESVI = 1.10, p = 0.03). A high RVMI was also associated with all-cause mortality (HR per increase of 5 mL/m2 RVMI = 1.75, p < 0.001).After adjusting for age and sex, only RVMI remained a significant predictor of MACCEs and all-cause mortality (p < 0.05 for both). After adjusting for multiple clinical variables, RVMI remained significantly associated with all-cause mortality (p = 0.005).
Conclusion
RVMI measured on preoperative cardiac MRI was an independent predictor of long-term outcomes in patients who underwent TV surgery for functional TR.

24 mm² (sensitivity, 76.5%; specificity 64.8%), and the area under the ROC curve (AUC) was 0.72. For ASR(area), the cut-off value was > 1.58 (sensitivity, 76.5%; specificity, 58.0%) and the AUC was 0.64. Multivariable Cox regression showed that ARO > 24 mm² (hazard ratio = 3.79, p = 0.020) was a potential independent parameter for recurrent 3 + AR. ROC for the linear regression model showed that the AUC for both ARO and ASR(area) was 0.73 (95% confidence interval, 0.64–0.81, p < 0.001).CONCLUSION: ARO and ASR(area) detected on preoperative cardiac CT would be potentially helpful for identifying AR patients who may benefit from the David operation.]]>
