RÉSUMÉ

Background@#Despite medical advancements in neonatal survival rates, many children have poor neurological outcomes. Because the law in Korea restricts the withdrawal of lifesustaining treatment to only cases of imminent death, treatment discontinuation may not be an option, even in patients with poor neurological prognosis. This study investigated the opinions of the general population and clinicians regarding life-sustaining treatment withdrawal in such cases using hypothetical scenarios. @*Methods@#We conducted a cross-sectional study on the general population and clinicians using a web-based questionnaire. The sample of the general population from an online panel comprised 500 individuals aged 20–69 years selected by quota sampling. The clinician sample comprised 200 clinicians from a tertiary university hospital. We created hypothetical vignettes and questionnaire items to assess attitudes regarding mechanical ventilation withdrawal for an infant at risk of poor neurological prognosis due to birth asphyxia at 2 months and 3 years after the incidence. @*Results@#Overall, 73% of the general population and 74% of clinicians had positive attitudes toward mechanical ventilator withdrawal at 2 months after birth asphyxia. The proportion of positive attitudes toward mechanical ventilator withdrawal was increased in the general population (84%, P < 0.001) and clinicians (80.5%, P = 0.02) at 3 years after birth asphyxia.Religion, spirituality, the presence of a person with a disability in the household, and household income were associated with the attitudes of the general population. In the multivariable logistic regression analysis of the general population, respondents living with a person with a disability or having a disability were more likely to find the withdrawal of the ventilator at 2 months and 3 years after birth asphyxia not permissible. Regarding religion, respondents who identified as Christians were more likely to find the ventilator withdrawal at 2 months after birth asphyxia unacceptable. @*Conclusion@#The general population and clinicians shared the perspective that the decision to withdraw life-sustaining treatment in infants with a poor neurological prognosis should be considered before the end of life. A societal discussion about making decisions centered around the best interest of pediatric patients is warranted.

RÉSUMÉ

Cardiac tamponade (CT) is a rare but potentially lethal complication associated with central venous catheters (CVCs). We present a 6-year-old boy who developed CT after CVC insertion in the right internal jugular vein, with its tip in the inferior vena cava. Initially, he was hospitalized to a tertiary hospital with presumptive diagnoses of pneumonia and left ankle cellulitis. Three days after CVC placement, he developed CT, manifesting as recurrent episodes of hypotension and bradycardia. Once a bedside echocardiography showed CT, pericardiocentesis was performed, resulting in successful resuscitation. Pericardiocentesis revealed a milk-appearing pericardial fluid, indicating chylopericardium. The boy also underwent debridement and joint irrigation of the left ankle, which turned out to be osteomyelitis. Although CVC tips in most reported CVC-related CTs have been commonly located in the right atrium, our case featured a tip located in the inferior vena cava. Additionally, chylopericardium was likely due to the extravasation of total parenteral nutrition fluid, rather than the usual causes, such as recent thoracic surgery. Understanding the mechanisms behind chylopericardium associated with CVCs and timely pericardiocentesis is crucial for improving the outcomes.

RÉSUMÉ

It is challenging to treat ventriculitis with parenteral treatment alone in some cases because of the difficulty involved in maintaining an appropriate level of antibiotics in cerebrospinal fluid (CSF). We report two cases of ventriculitis who did not respond to intravenous (IV) antibiotics but were successfully treated with intraventricular antibiotics using IV agents. The first case was a four-month-old male patient with X-linked hydrocephalus.He showed ventriculitis due to Klebsiella pneumoniae not producing extended-spectrum β-lactamase and susceptible to third-generation cephalosporins and gentamicin, following ventriculoperitoneal (VP) shunt. His condition did not improve during the 47 days of treatment with IV cefotaxime and meropenem. We achieved improvement in clinical presentation and CSF profile after three times of intraventricular gentamicin injection. The patient was discharged from the hospital with antiepileptic drugs. The second case was a six-month-old female patient with a history of neonatal meningitis complicated with hydrocephalus at one month of age, VP shunt at two months of age, followed by a methicillinresistant coagulase-negative staphylococci (CoNS) shunt infection with ventriculitis after the shunt operation. CoNS ventriculitis recurred four weeks later. We failed to treat intractable methicillin-resistant CoNS ventriculitis with IV vancomycin for ten days, and thus intraventricular antimicrobial treatment was considered. Five times of intraventricular vancomycin administration led to improvement in clinical parameters. There were only neurological sequelae of delayed language development but no other major complications. Patients in these two cases responded well to intraventricular antibiotics, with negative CSF culture results, and were successfully treated for ventriculitis without serious complications.

RÉSUMÉ

BACKGROUND: Endothelial dysfunction has been documented in patients with type 2 diabetes especially when combined with hypertension. We prospectively investigated the effects of pioglitazone in improving endothelial function in hypertensive type 2 diabetic patients during the 6-month follow-up. METHODS: Hypertensive type 2 diabetic patients were randomly assigned to pioglitazone (n = 25) or placebo (n = 25). Primary endpoint was to compare changes in brachial artery flow-mediated dilation (baFMD) between the 2 groups during the 6-month follow-up. Secondary endpoints were to compare changes in the circulating levels of microRNA-17, -21, 92a, -126, and -145 which have been known as indicators of endothelial cell migration and atherosclerosis progression during the 6-month follow-up. Inflammatory markers such as interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), high-sensitive C-reactive protein, adiponectin, soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were compared during the follow-up. RESULTS: The prevalences of risk factors such as hyperlipidemia, smoking, stroke, and family history of coronary artery disease did not show significant differences between the 2 groups. Increases in baFMD (0.33 +/- 0.34 mm vs. 0.02 +/- 0.25 mm, p < 0.05, respectively) and in the level of circulating microRNA-21 (0.23 +/- 0.05 vs. -0.06 +/- 0.04, p < 0.05, respectively) were significantly greater in the pioglitazone group when compared to the placebo group during the 6-month follow-up. No significant differences in the prevalences of new onset heart failure, fracture, and bladder cancer were noted during the follow-up between the 2 groups. Decreases in the levels of inflammatory marker such as IL-6 (-2.54 +/- 2.32 pg/mL vs. -1.34 +/- 2.12 pg/mL, p < 0.05, respectively), TNF-alpha (-1.54 +/- 1.51 pg/mL vs. 0.14 +/- 1.12 pg/mL, p < 0.05, respectively), sICAM-1 (-39 +/- 52 ng/mL vs. 6 +/- 72 ng/mL, p < 0.05, respectively), and sVCAM-1 (-154 +/- 198 ng/mL vs. -11 +/- 356 ng/mL, p < 0.05, respectively) were significantly greater in the pioglitazone group compared to the placebo group during the follow-up. CONCLUSIONS: In hypertensive type 2 diabetic patients, pioglitazone may increase baFMD and circulatory microRNA-21 and decrease inflammatory cytokines including IL-6, TNF-alpha, sICAM-1, and sVCAM-1.

RÉSUMÉ

BACKGROUND: Increased abdominal obesity is clearly associated with metabolic diseases and associated with increased risk for atherosclerosis and cardiovascular diseases. But the mechanisms underlying these associations are not completely understood. The aim of this study was to correlate the regional body composition with pulse wave velocity in the overweight and obese women. METHODS: We investigated 104 overweight and obese participants. Regional body composition was distinguished by anthropometry, dual-energy X-ray absorptiometry, and computed tomography (CT). For estimates of arterial stiffness, we measured brachial ankle pulse wave velocity (baPWV). Fasting blood glucose, lipid parameters, CRP, and free fatty acid were measured. Pearson's correlation analysis and multiple regression analysis were conducted to identify the relationship between baPWV and regional body composition. RESULTS: Average age, fasting blood sugar, HDL-cholesterol, triglyceride, HOMA-IR, abdominal visceral fat area measured by CT, visceral fat area/ subcutaneous fat area (VSR), and visceral fat area/midthigh muscle area (VMR) were all significantly higher in the visceral obesity group than the subcutaneous obesity group. BaPWV was positively correlated with age, blood pressure, triglyceride, waist circumference, waist hip ratio, abdominal visceral fat area measured by CT, and VSR and inversely correlated with thigh subcutaneous fat area. In multiple regression models, after adjustment for confounding factors, baPWV was independently correlated with abdominal visceral fat area measured by CT (R2=0.560, P=0.006). CONCLUSION: Abdominal visceral fat area measured by CT was the only measurement positively associated with baPWV which explains the relationship of regional body composition and arterial stiffness.
