Comparison of liver resection for hepatocellular carcinoma in hepatitis B and hepatitis C-related cirrhotic patients.

BACKGROUND/AIMS: The differences of liver resection for hepatocellular carcinoma (HCC) between hepatitis B and C-related cirrhotic liver remain unknown. This study compares the surgical results of HCC in hepatitis B and hepatitis C-related cirrhotic patients in an area endemic of hepatitis B. METHODOLOGY: A retrospective comparison of the clinicopathological features and early and long-term results of 110 cirrhotic patients with seropositive hepatitis B surface antigen only (group B) and 55 patients with seropositive anti-hepatitis C antibody only (group C) was carried out. RESULTS: Group C patients were older, had a lower serum alpha-fetoprotein level, greater indocyanine retention rate, and higher incidence of multicentric tumors. Tumor size was larger and there was a higher incidence of combined satellite nodules in group B patients. There were no significant differences in operative morbidity and mortality between the two groups. Group B patients had a slightly shorter disease-free interval (p = 0.07) but a better actuarial survival rate (p = 0.05) than group C patients. CONCLUSIONS: The hepatitis status did not affect the operative risks in cirrhotic livers. However, after resection of HCC, poorer liver functional reserve in hepatitis C-related cirrhotic patients caused poorer actuarial survival rate when compared with hepatitis B-related cirrhotic patients.

Congenital complete heart block.

Congenital complete heart blocks (CCHB) are mostly related to the neonatal lupus syndrome. The purpose of this paper was to assess the clinical spectrum of CCHB in our hospital. Nine patients were retrospectively enrolled between 1994 and 1999. The birth history, electrocardiography, 24-hour Holter monitoring, pacemaker insertion and its complications, maternal disease, and maternal and infant autoantibody levels were studied. All nine cases were diagnosed prenatally. Hydrops fetalis was noted in five (55.6%). Six cases were live births and the other three were terminated. No anatomical heart defects were noted. Initial electrocardiography revealed the atrial rates ranged from 150 to 166 beats per minute. The minimal ventricular rates ranged from 46 to 80 beats per minute. VVI mode pacemakers were inserted through xyphoid approach in all live-birth infants. Complications were noted in three of them (50%). Antinuclear antibody and anti-SSA/Ro antibody were positive in all 8 mothers (100%). The anti-SSB/La antibody was positive in 6 of the eight mothers (75%). Five infants tested positive for anti-SSA/Ro antibody. None of the infants tested positive for anti-SSB/La antibody. In conclusion, all CCHBs in our series were associated with maternal autoantibodies. Because of high complication rate of permanent pacemaker insertion during the neonatal period, it should be restricted in certain conditions.

Limited cutaneous systemic sclerosis: report of one case.

We report a case of systemic sclerosis, limited type, in a 5 year old boy in Taiwan. He presented with erythema, tight skin over his face and digits, subcutaneous calcification, telangiectasis, as well as Raynaud's phenomenon. The laboratory data showed weakly positive antinuclear antibody (ANA), and Topoisomerase 1 antibody (anti-Scl-70) titers. However his esophagogram, CO diffusion capacity, as well as cardiac and renal function were all normal. He suffered from the skin change for 2 to 3 years before visiting our pediatric clinic when he was 7 years old. We gave him Dipyridamole, D-penicillamine, Colchicine, and Nifedipine. There was some remission of the scleroderma and Raynaud's phenomenon after our treatment.

Ferromagnetism and MR imaging: safety of carotid vascular clamps.

Metallic extracranial carotid vascular clamps of the Selverstone, Crutchfield, Poppen-Blaylock, Salibi, Kindt, and tantalum varieties have been placed for treatment of large, giant, or inoperable intracranial aneurysms. To ascertain what adverse effect, if any, MR imaging would have on these clamps, magnetic deflection at 1.5 T was measured for various carotid clamps. Marked magnetic deflection (and torque) was displayed by stainless steel Poppen-Blaylock clamps. Relatively mild magnetic deflection was displayed by the stainless steel Selverstone, Salibi, Crutchfield, and Kindt clamps. Three patients with previously placed carotid clamps (two Selverstone, one Salibi) and one patient with a nonferromagnetic tantalum carotid clip had cranial or cervical MR studies at field strengths ranging from 0.35 to 0.60 T. No patient experienced any discomfort or neurologic sequelae as a result of MR imaging. Although the ferromagnetic clamps created severe "black-hole" artifacts and image distortion within the cervical and facial regions, no significant image degradation was apparent during spin-echo imaging of the brain. The tantalum clip created a far smaller MR artifact than did ferromagnetic clamps and allowed effective spin-echo and gradient-echo imaging in the cervical region. Our findings indicate that most patients with carotid vascular clamps (and nonferromagnetic clips) can probably be imaged safely with MR.

[Hemolytic disease of the newborn caused by maternal irregular antibody anti-E: report of one case].

A 3390 gm male baby was born smoothly at 41 weeks' gestation to a 35-year-old, gravida 3, para 3, mother by spontaneous vaginal delivery at this hospital. The mother denied ever having received a blood transfusion. Her first two uneventful pregnancies had resulted in two healthy fullterm infants. Physical examination of the baby showed normal, until 15 hours of age, when apparent jaundice with serum total bilirubin concentration up to 21 mg/dl was noted. The blood types of both baby and mother were group A, Rh(D) positive. Compatibility testing for exchange blood transfusion with group A whole blood showed positive reaction due to the presence of an irregular antibody. Two exchange blood transfusions were performed in the same day with compatible blood. Thereafter, the patient's condition was much improved, he was discharged one week later. The irregular antibody--anti-E was identified in both baby and mother. The maternal RBC phenotyping was CCDee (R1R1), and the baby, CcDEe (R1R2).
