Liver Transplantation and Abuse of Drugs and Alcohol: A Correlation Between Scales of the MMPI-2.

BACKGROUND: Clinical practice requires an accurate psychological assessment of subjects with clinical history of alcohol abuse and/or substance abuse (abuse history [AH]) for therapeutic choice. This study aims to identify significant correlations between the Minnesota Multiphasic Personality Inventory (MMPI)-2 scales in patients awaiting liver transplantation. METHODS: We evaluated a personality questionnaire containing MMPI-2 scales in the sample of 308 patients (81.8% males and 18.2% females) awaiting liver transplantation. The AH group composed 44.49% of patients and in the abuse free (AF) group, 55.51%. Scales were compared using Shapiro-Wilk test and Mann-Whitney U test. Interrelationships were examined using Spearman's correlation. RESULTS: This analysis found 27 scales of the MMPI-2 that were statistically different between 2 groups (AF and AH). In the AH group, we found a significant correlation between the following pairs of scales: Schizophrenia Scale (Sc) with the Addictions Potential Scale, Social Introversion scale (Si) with the Psychopathic Deviate scale (Pd), and Social Discomfort scale with Pd; the ES scale was negatively correlated with the Sc and Si scales. This interim study showed that the understanding of these indicators is crucial both for the assessment accuracy and for a prediction of the degree of therapy compliance after the transplantation. CONCLUSIONS: The scales of the MMPI-2 indicated a marked tendency to emotional rigidity, a lack of self-esteem and susceptibility judgment. Social introversion and social discomfort trends lead to impulsive behavior and deviant actions that combine poorly with good compliance with treatment.

Radio-frequency thermal ablation (RFTA) of small hepatocellular carcinoma in patients with cirrhosis. Experience at a single tertiary referral center.

AIM: Radio-frequency thermal ablation (RFTA) may prolong the survival of patients with small hepatocellular carcinoma (HCC) associated with cirrhosis. The aim of this study was to evaluate efficacy and safety of RFTA. METHODS: We performed the Kaplan-Meier analysis to estimate the survival rate in 69 consecutive patients with HCC (mean age 66+/-6.5 years; 44/25 male/female; 56 Child-Pugh class A and 13 Child-Pugh class B) treated by RFTA. A single lesion was observed in 60/69 (87%), two lesions in 8/69 (11.6 %), and 3 lesions in 1/69 (1.4 %) of patients. The tumor size was = or <3 cm in 60/69 (87%). RESULTS: Twenty-two patients died during follow-up. Overall survival rates were 81%, 66%, and 46% at 1-, 2-, and 3-years, respectively. Cancer-free survival rates were 64% at 1 year, 30% at 2 years and 25% at 3 years. The 3-years rate of appearance of separate new lesions and local recurrence were 27.5% (19/69) and 26 % (18/69). CONCLUSIONS: Our study shows that patients with HCC and compensated cirrhosis may benefit from RFTA treatment, especially for tumors = or <3 cm. Nevertheless, the high rate of recurrence (both local and distant) points out the palliative role of this therapy.

Familial incidence of twinning.

The frequency of twinning among women who have already borne twins, the 'repeat frequency', is significantly higher than in the general population. Individual propensity is not necessarily genetic in origin, but pedigree studies (for reviews see refs 1, 2) confirm that twinning is a family trait. Studies based on archives restrict this conclusion to dizygotic (DZ) twinning and the maternal side, while studies based on interviews of relatives of twins find monozygotic (MZ) twinning and the paternal side also to be involved. However, interview studies can overestimate, while archive studies can underestimate, the real frequency of twinning. We have now analysed the incidence of twinning in the families of 950 zygosity-determined, unselected twin pairs under complete ascertainment. Our results indicate that a propensity to MZ twinning, as well as one to DZ twinning, can be inherited through the maternal line, and that the two mechanisms of twinning might be related. We have also found a paternal role in DZ, but not in MZ twinning.
