ABSTRACT

Objective@#This paper presents a review of the current state of child and adolescent mental health literacy and provides current evidence of the economic impact of a pediatric mental health literacy (MHL) training program. @*Methods@#Employing a case-series-comparison design, physician referrals to urgent and specialized mental health services were linked with patient-specific information comparing referrals from MHL participants and non-participating physicians. The economic impact analysis was based on changes in the admitted referral frequency and lengths of stay for the MHL group, compared to themselves pretraining, and over the same time period compared to non-participating physicians. @*Results@#Average scheduled ambulatory admission rates per physician remained constant for trained and untrained pre-post groups. Average scheduled ambulatory admission wait time and length of stay reduced significantly post-training for MHL-trained physicians compared to pre-training and untrained physicians. In addition to reductions in length of stay, the total bed costs saving for emergency/ inpatients admission deferrals was $2,932,112 or about $20,000 per MHL-trained physician. @*Conclusion@#The estimated economic impact of the MHL training shows a substantial return on investment and supports wider implementation. The MHL training program should be a key feature of mental health reform strategies, as well as continuing and undergraduate medical education.

ABSTRACT

Percutaneous interventional procedures under image guidance, such as biopsy, ethanol injection therapy, and radiofrequency ablation play important roles in the management of hepatocellular carcinomas. Although uncommon, the procedures may result in tumor implantation along the needle tract, which is a major delayed complication. Implanted tumors usually appear as one or a few, round or oval-shaped, enhancing nodules along the needle tract on CT, from the intraperitoneum through the intercostal or abdominal muscles to the subcutaneous or cutaneous tissues. Radiologists should understand the mechanisms and risk factors of needle tract implantation, minimize this complication, and also pay attention to the presence of implanted tumors along the needle tract during follow-up.

ABSTRACT

Needle tract implantation of hepatocellular carcinoma (HCC) is a rare complication of percutaneous biopsy, and it is largely associated with end-cutting needles or aspiration biopsy. The CT findings that have been reported include oval or round soft tissue nodules with persistent contrast enhancement along the needle tract, mostly in the subcutaneous tissue or the intercostal muscle layers. In this report, we describe a case of needle tract implantation of HCC after US-guided percutaneous biopsy with an 18G tru-cut needle.

ABSTRACT

PURPOSE: To evaluate the usefulness of screening liver ultrasonography (US) for hepatocellular carcinoma (HCC) detection in patients with chronic hepatitis or hepatic cirrhosis caused by hepatitis B virus (HBV). MATERIALS AND METHODS: A retrospective study was performed with 1,189 patients with clinical hepatopathy caused by HBV who underwent screening liver US for HCC detection at least twice. All patients were followed up with liver US examinations (mean, 8.3 times), CT, or MR for at least 3 months (range, 3-102 months; mean, 47 months) for the detection of HCC. The study population was divided into two groups: chronic hepatitis (n=492) and hepatic cirrhosis (n=697), which was further divided into two groups with (n=156) or without (n=541) evident shrinkage. The radiologic examinations that had detected HCC for the first time were analyzed and compared between the groups. RESULTS: Among 20 (4.1%) patients with chronic hepatitis and 132 (18.9%) patients with hepatic cirrhosis diagnosed as HCC, screening US was the modality of detection in 17 (85.0%) of 20 patients with chronic hepatitis and 76 (57.6%) of 132 patients with hepatic cirrhosis (p=0.038, Chi-square test). The detection rate of HCC on screening US between the chronic hepatitis and hepatic cirrhosis with evident shrinkage (51.4%, 19/37) showed a significant difference (p=0.027, Chi-square test). CONCLUSION: For chronic liver disease caused by HBV, screening US for HCC detection is more useful in patients with chronic hepatitis than with hepatic cirrhosis with evident shrinkage.

ABSTRACT

OBJECTIVE: To evaluate the usefulness of multidetector-row computed tomography (CT) in the evaluation of reperfused myocardial infarction. MATERIALS AND METHODS: Eleven rabbits were subjected to 90-min occlusion of the left anterior descending coronary artery followed by reperfusion. Multidetector-row CT was performed 31 hours+/-21 after the procedure and preand post-contrast multiphase helical CT images were obtained up to 10 min after contrast injection. The animals were sacrificed after 30 days and histochemical staining of the resected specimens was perfomed with 2'3'5-triphenyl tetrazolium chloride (TTC). RESULTS: In all 11 cases, the areas of myocardial infarction demonstrated with TTC-staining were identified on the CT images and the lesions showed hypoenhancement on the early phases up to 62 sec and hyperenhancement on the delayed phases of 5 min and 10 min compared with normal myocardial enhancement. The percentage area of the lesion with respect to the left ventricle wall on CT was significantly correlated with that of the TTC-staining results (p < 0.001 for both early and delayed phase CT) according to the generalized linear model analysis. The areas showing hypoenhancement on early CT were significantly smaller than those with hyperenhancement on delayed CT (p < 0.0001). CONCLUSION: Multidetector-row CT may be useful in the detection and sizing of reperfused myocardial infarction.
