[Comparison of doxorubicin-eluting bead transarterial chemoembolization (DEB-TACE) with conventional transarterial chemoembolization (TACE) for the treatment of hepatocellular carcinoma].

Objective: To compare conventional transarterial chemoembolization (TACE) with doxorubicin-eluting bead transarterial chemoembolization (DEB-TACE) for the treatment of hepatocellular carcinoma, evaluating the tumor response, complications after treatment, and survival.

Material And Methods: We present 72 patients diagnosed with hepatocellular carcinoma treated consecutively between January 2000 and December 2009. We studied 25 patients treated with TACE (Group A) and 47 patients treated with DEB-TACE (Group B); adriamycin (doxorubicin) was the chemotherapy agent used in both groups.

[The rabbit as an experimental model: technique for the induction of vascular lesions and incidents].

Objective: To describe the process for inducing atherogenic lesions in rabbits, to show the damage to vessels caused by two different caliber balloon catheters, and to show the usefulness of ultrasonography in the quantification of vascular damage.

Material And Methods: We used 36 rabbits. We studied the levels of triglycerides and cholesterol and examined the aorta and iliac arteries by ultrasonography.

[Coronary artery calcium quantification with non-ECG-gated low-radiation dose CT of the chest].

Objective: To evaluate the feasibility of quantifying coronary artery calcification in low-radiation dose chest CT (LDCT) studies performed in an early lung cancer detection program by comparing the results of this technique with those of dedicated retrospectively ECG-gated cardiac CT.

Material And Methods: After obtaining informed consent, we evaluated the CT studies of 48 consecutive asymptomatic smokers (44 male, 4 female; mean age 59.7 years) included in an early lung cancer detection trial who underwent multislice LDCT (Volume Zoom, Siemens) of the chest and a retrospectively ECG-gated cardiac CT specifically dedicated to quantifying coronary artery calcification.

[Treatment of lacrimal duct obstruction with a Tear-Leader stent].

Purpose: To compare the effectiveness and patency of the TearLeader stent (PBN) for treatment of lacrimal system obstruction.

Methods: A prospective study of 68 patients referred from the ophthalmology department with suspicion of lacrimal system obstruction. We placed 74 TearLeader PBN stents.

[Intestinal pneumatosis and portomesenteric gas: a case review].

Intestinal pneumatosis (presence of gas in the intestinal wall and in the portomeseteric veins) is an infrequent clinical situation that has been associated with extended bowel necrosis and fatal outcome. However, there are other reasons that can justify these findings without such an outcome. Recent advances in diagnostic imaging techniques, especially multislice computerized tomography (MSCT), have allowed precise and quick diagnosis of these entities.
