Investigating Up-to-Seven Criteria and APRI (AST Platelet Ratio) as Prognostic Factors in Intermediate-Stage Hepatocellular Carcinoma Patients Who Received Transarterial Chemoembolization.

BACKGROUND: Transarterial chemoembolization (TACE) is one of the locoregional treatments for intermediate-stage hepatocellular carcinoma (HCC). Multidetector computed tomography (MDCT) is a widely used diagnostic tool for HCC. It can also evaluate tumor size, tumor number, and tumor invasion. This study aimed to determine the median survival time in intermediate-stage HCC patients who underwent TACE and to find out  prognostic factors influencing patients' survival time after TACE. METHODS: A computerized search of medical record database in Maharaj Nakorn ChiangMai Hospital from January 2016 to December 2019 revealed 187 intermediate-stage HCC patients who received TACE as the first-line treatment. RESULTS: The median survival time of patients in this study was 9.9 months (95% CI: 8.3-11.6). The patients with aspartate aminotransferase-to-platelet ratio (APRI) less than 0.5 had a significantly better median survival time as compared with patients with APRI ratio more than 0.5; (13.2 months versus 9.9 months, p-value < 0.05). Univariate and multivariate Cox regression analysis demonstrated that tumor number > 7 and tumor size > 5 centimeters (cm) could be considered as independent parameters predicting poor overall survival time in the sufferers (HR 2.64 95%CI 1.68-4.15 and HR 2.38 95%CI 1.32-4.31, respectively). CONCLUSION: Based on our findings, patients with intermediate-stage HCC who received TACE had a lower median survival time compared to previous studies. However, we identified APRI less than 0.5, tumor size less than 5 cm, and tumor number less than 7 as prognostic factors improving survival time in intermediate-stage HCC patients.

Ultrasound Use in Diagnosis and Management of Venous Leg Ulcer.

Leg ulcers caused by venous diseases are effectively assessed by Doppler ultrasonography. The examination provides clear anatomical and physiological information for the diagnosis, treatment planning, and real-time guiding during the surgical treatment. Diagnostic Doppler ultrasonography assesses deep, superficial, and perforator veins, starting from patency assessment by direct visualization and simply compression test. The internal flow can be assessed by pulse wave analysis, which is used for rule out downstream flow obstruction and valvular incompetence. The venous valve function of deep, superficial, and perforator systems can be evaluated by measuring the time of the retrograde flow after flow augmentation performing in the upright position. At the end of the study, the venous map will be obtained and this map will guide clinicians to target treatment where the culprit is. The ultrasound technology has made a big shift in the treatment in the venous disease. In recent years, after the evolution and wide availability of ultrasound, newer treatment modalities have emerged for venous treatment. These include endovenous thermal ablation, endovenous adhesive closure, and ultrasound-guided foam sclerotherapy. Patients no longer require general anesthesia or hospitalization. Therefore utilization of duplex ultrasound has also surged and played an essential role in both diagnosis and therapy in venous ulcer. This article has dedicated to reviewing basic anatomy, the technique in diagnosis, and treatment.

Case Series of HIV Infection-Associated Arteriopathy: Diagnosis, Management, and Outcome Over a 5-Year period at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai University.

Patients infected with human immunodeficiency virus (HIV) can present with 4 pathology types: drug-induced vasospasm (ergotism), arterial limb ischemia, critical limb ischemia, and aneurysm. Although these problems are common vascular problems, they result in increased morbidity and mortality in HIV-infected patients, especially aneurysm. Patients with these problems tend to be diagnosed with difficulty because of atypical symptoms and signs. Because of lack of data in treatment outcome literature, our report explores and provides information on HIV infection-related arteriopathy. There were 17 patients in our 5-year review. There was no death in patients except the aneurysm type. The survival of aneurysm patients was significantly lower than from other pathologies (P = .003). Our case series showed good short-term outcome, and patients were not at risk for less beneficial surgical procedures.
