Transcatheter embolization of an aortobronchial fistula with N-butyl cyanoacrylate

Aortobronchial fistula is a fatal complication after thoracic aortic surgery. So far, treatment options for aortobronchial fistula have included surgical and endovascular stent-graft methods. Herein, a case of an aortobronchial fistula with life-threatening hemoptysis managed with transcatheter embolization of the fistula with N-butyl cyanoacrylate is reported. For the patient with an aortobronchial fistula who cannot be treated by surgical or endovascular stent-graft methods, transcatheter embolization of the fistula may be the only available life-saving method.     

Profiling health and health-related services for children with special health care needs with and without disabilities

ObjectiveThe aims of this study were to profile and compare the health and health services characteristics for children with special health care needs (CSHCN), with and without disabilities, and to determine factors associated with unmet need.MethodsSecondary data analysis of the 2005–2006 National Survey of Children with Special Health Care Needs was conducted. The sociodemographics, health, and health services of CSHCN with and without disabilities were compared. Multivariable logistic regression was employed to examine factors associated with unmet need for health services.ResultsChildren from minority racial and ethnic groups and children living in or near poverty were over-represented among CSHCN with disabilities, compared with other CSHCN. Statistically higher percentages of CSHCN with disabilities had behavioral problems (39.6% vs 25.2%), anxiety/depressed mood (46.1% vs 24.0%), and trouble making/keeping friends (38.1% vs 15.6%) compared with other CSHCN. Thirty-two percent of CSHCN with disabilities received care in a medical home compared with 51% of other CSHCN. CSHCN with disabilities had higher rates of need and unmet need than other CSHCN for specialty care, therapy services, mental health services, home health, assistive devices, medical supplies, and durable medical equipment. The adjusted odds of unmet need for CSHCN with disabilities were 71% higher than for other CSHCN.ConclusionCSHCN with disabilities had more severe health conditions and more health services need, but they less commonly received care within a medical home and had more unmet need. These health care inequities should be amenable to policy and health service delivery interventions to improve outcomes for CSHCN with disabilities.     

Usefulness of presepsin in the diagnosis of sepsis in a multicenter prospective study

The clinical usefulness of presepsin for discriminating between bacterial and nonbacterial infections (including systemic inflammatory response syndrome) was studied and compared with procalcitonin (PCT) and interleukin-6 (IL-6) in a multicenter prospective study. Suspected sepsis patients (n = 207) were enrolled into the study. Presepsin levels in patients with systemic bacterial infection and localized bacterial infection were significantly higher than in those with nonbacterial infections. In addition, presepsin, PCT, and IL-6 levels in patients with bacterial infectious disease were significantly higher than in those with nonbacterial infectious disease (P < 0.0001, P < 0.0001, and P < 0.0001, respectively). The area under the receiver operating characteristic curve was 0.908 for presepsin, 0.905 for PCT, and 0.825 for IL-6 in patients with bacterial infectious disease and those with nonbacterial infectious disease. The cutoff value of presepsin for discrimination of bacterial and nonbacterial infectious diseases was determined to be 600 pg/ml, of which the clinical sensitivity and specificity were 87.8 % and 81.4 %, respectively. Presepsin levels did not differ significantly between patients with gram-positive and gram-negative bacterial infections. The sensitivity of blood culture was 35.4 %; that for presepsin was 91.9 %. Also there were no significant differences in presepsin levels between the blood culture-positive and -negative groups. Consequently, presepsin is useful for the diagnosis of sepsis, and it is superior to conventional markers and blood culture.     

Quantification of tumor vascularity with contrast-enhanced ultrasound for early response of transcatheter arterial chemoembolization for hepatocellular carcinoma: a report of three cases

Many contrast-enhanced ultrasound (CE-US) studies have been conducted by qualitative analysis of blood flow, such as classification of enhancement pattern. We evaluated early response of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) by quantitative analysis of intratumoral vascularity with CE-US in three patients. Three patients (one man, two women) with HCCs were treated in July 2009. CE-US with perfluorocarbon microbubbles (Sonazoid) and CT were performed serially before and 5 days after TACE. Post-processing enhancement intensity on US was analyzed to determine mean transit time (s), time to peak (s), enhancement peak intensity (dB), and “A” (scaling factor) by ultrasound quantification software after the data were fitted to a gamma variate curve. Mean transit time was prolonged by TACE in all three patients. Mean transit time rates on CE-US were 64.3, 33.8, and 65.6%, respectively, whereas the avascular rates on CT were 59.07, 31.71, and 62.25%, respectively. Mean transit time rates on CE-US approximated avascular rates on CT. Mean transit time rate may quantitatively indicate the early response of HCC to TACE.     

Effects of endolymphatic sac drainage with steroids for intractable Meniere's disease: a long-term follow-up and randomized controlled study

OBJECTIVE: Meniere's disease is a common inner ear disease with an incidence of 15 to 50 per 100,000 population. Since Meniere's disease is thought to be triggered by an immune insult to the inner ear, we examined intraendolymphatic sac application of steroids as a new therapeutic strategy for intractable Meniere's disease. STUDY DESIGN: Prospective randomized controlled study. METHODS: Between 1996 and 2005, we enrolled and assigned 197 intractable Meniere's patients to three groups in a randomized controlled trial: Group I (G-I)- patients who underwent endolymphatic sac drainage and steroid-instillation; Group II (G-II)-those who underwent endolymphatic sac drainage without steroid-instillation; and Group III (G-III)-those who declined endolymphatic sac drainage. Definitive spells and hearing in all three groups were determined for 2 to 7 years after treatment. RESULTS: According to the 1995 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria, 2-year results demonstrated that vertigo was completely controlled in 88.0% of patients in G-I (n = 100), 85.1% of patients in G-II (n = 47), and 8.0% in G-III (n = 50). Statistically, G-I = G-II>G-III. Hearing was improved in 49.0% of patients in G-I, 31.9% in G-II, and 6.0% in G-III (G-I>G-II>G-III). Results after 7 years showed that vertigo was completely controlled in 78.8% of patients in G-I, 79.2% in G-II, and 25.0% in G-III (G-I = G-II>G-III). Hearing improved in 36.5% of patients in G-I, 8.3% in G-II, and 0.0% in G-III (G-I>G-II = G-III). CONCLUSIONS: From non-surgical observation in G-III for at least 7 years after treatment, steroids instilled into endolymphatic sac in G-I patients significantly improved hearing in intractable Meniere's patients, more so than endolymphatic sac drainage without steroids in G-II patients.
