Platelet Count Does Not Predict Bleeding in Cirrhotic Patients: Results from the PRO-LIVER Study.

OBJECTIVES: Thrombocytopenia is a hallmark for patients with cirrhosis and it is perceived as a risk factor for bleeding events. However, the relationship between platelet count and bleeding is still unclear. METHODS: We investigated the relationship between platelet count and major or clinical relevant nonmajor bleedings during a follow-up of ∼4 years. RESULTS: A total of 280 cirrhotic patients with different degrees of liver disease (67% males; age 64±37 years; 47% Child-Pugh B and C) were followed up for a median of 1,129 (interquartile range: 800-1,498) days yielding 953.12 patient-year of observation. The annual rate of any significant bleeding was 5.45%/year (3.57%/year and 1.89%/year for major and minor bleeding, respectively). Fifty-two (18.6%) patients experienced a major (n=34) or minor (n=18) bleeding event, predominantly from gastrointestinal origin. Platelet counts progressively decreased with the worsening of liver disease and were similar in patients with or without major or minor bleeding: a platelet count ≤50 × 103/µl was detected in 3 (6%) patients with and in 20 (9%) patients without any bleeding event. Conversely, prothrombin time-international normalized ratio was slightly higher in patients with overall or major bleeding. On Cox proportional hazard analysis, only a previous gastrointestinal bleeding (hazard ratio (HR): 1.96; 95% confidence interval: 1.11-3.47; P=0.020) and encephalopathy (HR: 2.05; 95% confidence interval: 1.16-3.62; P=0.013) independently predicted overall bleeding events. CONCLUSIONS: Platelet count does not predict unprovoked major or minor bleeding in cirrhotic patients.

HBV reactivation in patients with HCV/HBV cirrhosis on treatment with direct-acting antivirals.

Anecdotal reports suggest that patients with chronic hepatitis C virus (HCV) hepatitis and overt or occult hepatitis B virus (HBV) coinfection may reactivate HBV when HCV is suppressed or cleared by direct-acting antivirals (DAAs). We assessed the prevalence of overt or previous HBV coinfection and the risk of HBV reactivation in patients with HCV cirrhosis treated with DAAs. This was a retrospective cohort of 104 consecutive patients with HCV cirrhosis treated with DAAs. Serum HCV-RNA and HBV-DNA were tested at weeks 4, 8 and 12 of DAAs therapy and at week 12 of follow-up. At the start of DAAs, eight patients (7.7%) were HBsAg positive/HBeAg negative with undetectable HBV-DNA and low levels of quantitative HBsAg (four on nucleos(t)ide analogues [NUCs] and four inactive carriers), 37 patients (35.6%) had markers of previous HBV infection (25 anti-HBc positive, 12 anti-HBc/anti-HBs positive) and 59 (56.7%) had no evidence of HBV infection. Sixty-seven patients (64.4%) were HCV-RNA negative at week 4 and 98 (94.2%) achieved sustained virological response. All four HBsAg-positive patients treated with NUCs remained HBV-DNA negative, but three of four untreated patients showed an increase in HBV-DNA of 2-3 log without a biochemical flare and achieved HBV-DNA suppression when given NUCs. During or after DAAs, by conventional assay, HBV-DNA remained not detectable in all 37 anti-HBc-positive patients but in three of them (8.1%) HBV-DNA became detectable with a highly sensitive PCR. HBV reactivation is likely to occur in untreated HBV/HCV-coinfected cirrhotic patients when they undergo HCV treatment with DAAs. Pre-emptive therapy with NUCs should be considered in this setting. Anti-HBc-positive patients rarely reactivate HBV without clinical or virological outcomes.

Clinical course and management of acute and chronic viral hepatitis during pregnancy.

Pregnancy is a para-physiologic condition, which usually evolves without any complications in the majority of women, even if in some circumstances moderate or severe clinical problems can also occur. Among complications occurring during the second and the third trimester very important are those considered as concurrent to pregnancy such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, HELLP syndrome and acute fatty liver of pregnancy. The liver diseases concurrent to pregnancy typically occur at specific times during the gestation and they may lead to significant maternal and foetal morbidity and mortality. Commonly, delivery of the foetus, even preterm, usually terminates the progression of these disorders. All chronic liver diseases, such as chronic viral hepatitis, autoimmune hepatitis, Wilson's disease, and cirrhosis of different aetiologies may cause liver damage, independently from pregnancy. In this review we will also comment the clinical implications of pregnancies occurring in women who received a orthotopic liver transplantation (OLT) Therefore, the management of immunosuppressive therapy before and after the delivery in women who received liver transplant is becoming a relevant clinical issue. Finally, we will focus on acute and chronic viral hepatitis occurring during pregnancy, on management of advanced liver disease and we will review the literature on the challenging issue regarding pregnancy and OLT.

Prognostic Value of a Laboratory Index of Frailty in Older Patients Hospitalized for COVID-19: The COMEPA Study.

BACKGROUND: Several indexes based on clinical and laboratory tests to identify frailty and to predict mortality have been produced. Only two studies, mixing clinical and laboratory parameters were made about a frailty index made of laboratory tests (FI-Lab) and mortality in older patients hospitalized for COVID-19. The aim of this study was to explore the accuracy and precision of an FI-Lab constructed with some common bio-humoral tests and mortality in a cohort of patients hospitalized for COVID-19. METHODS: The FI-Lab was constructed using 40 different bio-humoral tests during the first four days of hospitalization, with a score from 0 to 1. The association between FI-Lab and mortality was assessed using a multivariate Cox's regression analysis, reported as hazard ratios (HRs) and 95% confidence intervals (CIs). The accuracy of the FI-Lab was reported as area under the curve (AUC) and the precision with the C-Index. RESULTS: 376 patients (mean age: 65 years; 53.7% males) were initially included. During the follow-up period, 41 deceased. After adjusting for five different factors, an FI-Lab value >0.54, the median value of our cohort, was associated with a relative risk about five times greater than lower values. Modeling FI-LAB as a continous variable, each increase in 0.01 points was associated with an increased risk in mortality of 8.4% (HR=1.084; 95%CI: 1.039-2.044). The FI-Lab was highly accurate (AUC=0.91; 95%CI: 0.87-0.95) and precise (C-Index=0.81) in predicting death. CONCLUSIONS: A simple index based on common laboratory tests can be used to predict mortality among older people hospitalized for COVID-19.

Oxidative profile in patients with colon cancer: effects of Ruta chalepensis L.

AIM: To verify the involvement of free radicals in tumor progression and to investigate the effects of an ethanolic extract of Ruta Chalepensis L. and of rutin in blood of patients with colon cancer. MATERIALS AND METHODS: Leaves of Ruta Chalepensis L. were collected in the area around Catania (Italy). For the preparation of the ethanol extract of leaves, an exhaustive extraction of 100 g of the drug was carried out in Soxhlet with 800 ml of 95% ethanol. Fifty-six patients with colorectal cancer were randomly selected for this study; among these, 34 were affected by an early stage (T1 N0 M0 according to scale), while 22 were affected by an advanced stage (T4, N1-2, M0) of cancer. Data obtained from these patients were compared with those of a control group consisting of 20 healthy subjects. Plasma of each sample was used for determining non-proteic antioxidant capacity, thiol groups, lipid hydroperoxides and nitrite/nitrate levels, evaluated by spectrophotometric tests. In addition, percentage of haemolysis was evaluated incubating (for 2 hours at 37 degrees C) erythrocyte suspension with a free radical donor (50 mM 2,2'-azobis-amidino propane chloridrate), in the presence or absence of ethanolic extract of Ruta Chalepensis L. (250 microg/ml) or rutin (1 mM). RESULTS: Non-proteic antioxidant capacity was significantly lower in cancerous patients than in healthy subjects (p < 0.001). This decrease was stage-related. In fact, non-proteic antioxidant capacity resulted lower in advanced than in early colorectal cancer (p < 0.001). The same significant stage-related decrease was observed in plasma thiol groups (p < 0.001). Coherently with the decrease in non-proteic antioxidant capacity and thiol groups, higher levels of lipid hydroperoxides and nitrite/nitrate were observed in patients with colorectal cancer with respect to healthy subjects (p < 0.001) and the increase in these markers of oxidative stress was related to the cancer stadiation. Neoplastic patients also showed an increased percentage of oxidative hemolysis respect to controls and the haemolytic damage was correlated with the stage of colon cancer. Both the extract of Ruta Chalepensis L. and rutin were able to protect erythrocytes from oxidative stress induced by the free radical donor, but the extract of Ruta Chalepensis L. was more effective than rutin. This protective effect was significant only in erythrocytes from patients with early colorectal group, whereas no significant modification was induced by Ruta Chalepensis L. or rutin in red blood cells from advanced colorectal cancer patients exposed to the same experimental conditions. CONCLUSION: Oxidative stress correlates with colon cancer stadiation and both the extract of Ruta chalepensis and rutin are able to protect red blood cells from radical-induced damage. However, their effects are significant in early stages of cancer. So these natural antioxidants might be usefull to prevent carcinogenesis and/or tumor progression.

Hemoperitoneum as severe and unusual complication in the stapler recto-anopexy for hemorrhoidal prolapse. Case report.

We report unusual but severe complication after Longo recto-anopexy for hemorrhoidal prolapse, i.e. large intramural hematoma of the rectum and subsequent hemoperitoneum. We make some assessment about the technique.

Serum BLyS/BAFF predicts the outcome of acute hepatitis C virus infection.

B-lymphocyte stimulator/B activating factor (BLyS/BAFF) is a tumour necrosis factor-family cytokine that plays a key role in generating and maintaining the mature B-cell pool. BLyS/BAFF expression by macrophages is stimulated by interferon-gamma and interleukin-10, and its serum levels are increased in chronic hepatitis C (CHC). The aim of this study was to assess serum levels of BLyS/BAFF in patients with acute hepatitis C (AHC) and correlate them with disease outcome. We studied 28 patients with AHC (14 males, mean age 59.3 +/- 15 years), followed for at least 7 months since onset, comparing them with 86 CHC patients and 25 healthy blood donors (HBD). BLyS/BAFF levels were assessed at baseline (within 4 weeks of onset) and during follow-up. BLyS/BAFF median levels were significantly higher in AHC (1485 pg/mL) than in CHC (1058 pg/mL) and in HBD (980 pg/mL) (P < 0.001). BLyS/BAFF levels were higher in AHC patients evolving to chronicity (1980 pg/mL) than in those with a self-limited course (1200 pg/mL), (P = 0.02). By logistic regression analysis, higher BLyS/BAFF levels were independently associated with persistence of HCV infection (OR 29.7; 95% CI: 1.73-508.20). High serum levels of BLyS/BAFF at onset of AHC can predict its evolution to chronic infection.

A focus on epidemiology of drug-induced liver injury: analysis of a prospective cohort.

OBJECTIVE: Drug-induced liver injury (DILI) is more often a challenge even for expert clinicians. Presently, there are limited data about the epidemiology, because the real incidence and prevalence of the disorder are underestimated, and further, sometimes the pharmacovigilance chain is unsuccessful as cases are largely underreported. We review available literature data and discuss our clinical experience regarding a prospective cohort of 185 patients with a diagnosis of DILI. MATERIALS AND METHODS: Significant papers were identified by literature search, and selected based on content including the epidemiology of DILI. By analyzing our prospective cohort, consecutively collected since January 2000 to December 2016 at our tertiary referral center for liver disease, we report the frequency of different drug classes involved in DILI and their related clinical outcomes. RESULTS: In our cohort of 185 patients, 56% were females and 44% males; the mean age was 53 years, even if about 70% of patients were 40 years old; only 2% had a previous chronic liver disease. At clinical presentation, 57.8% showed a hepatocellular pattern, whereas 18.3% a cholestatic and 23.2% a mixed one. Antibiotics were involved for 23.4%, NSAIDs for 35.5%, immunosuppressants for 10.9%, statins for 4.3%, anti-platelets and anti-psychiatric drugs for 7.6%, and other drugs for 9%. Regarding the evolution, antibiotics, NSAIDs, and immunosuppressant were frequently responsible for chronicity, whereas statins, anti-psychiatric and anti-platelets drugs were not. CONCLUSIONS: In this review, we discuss our clinical experience in the field of DILI, in which many efforts are required to reinforce the attention of a physician to the possibility that a patient with the acute liver disease could be diagnosed as a patient with DILI.

Sarcopenia is associated with severe liver fibrosis in patients with non-alcoholic fatty liver disease.

BACKGROUND: Sarcopenia recognises insulin resistance and obesity as risk factors, and is frequently associated with cardiometabolic disorders, including non-alcoholic fatty liver disease (NAFLD). AIM: To test the prevalence of sarcopenia and its relation with the severity of fibrosis (main outcome) and the entire spectrum of liver histology in patients with NAFLD. METHODS: We considered 225 consecutive patients with histological diagnosis of NAFLD (Kleiner score). The skeletal muscle index (%) (total appendicular skeletal muscle mass (kg)/weight (kg) × 100), a validated measure of sarcopenia, was assessed by bioelectrical impedance analysis. Sarcopenia was defined as a skeletal muscle mass index ≤37 in males and ≤28 in females. RESULTS: The prevalence of sarcopenia showed a linear increase with the severity of fibrosis, and severe fibrosis (F3-F4) was more than doubled in sarcopenia (48.3% vs. 20.4% in fibrosis ≤F2, P < 0.001). After adjusting for confounders, the association of sarcopenia with severe fibrosis was maintained (OR 2.36, CI 1.16-4.77, P = 0.01), together with age > 50 (OR 6.53, CI 2.95-14.4, P < 0.001), IFG/Diabetes (OR 2.14, CI 1.05-4.35, P = 0.03) and NASH (OR 13.3, CI 1.64-108.1, P = 0.01). Similarly, a significant association was found between sarcopenia and NASH (P = 0.01), steatosis severity (P = 0.006), and ballooning (P = 0.01), but only the association with severe steatosis was maintained (OR 2.02, CI 1.06-3.83, P = 0.03) after adjusting for confounders. CONCLUSIONS: In Western patients with NAFLD, with high prevalence of metabolic disorders and advanced liver disease, sarcopenia was associated with the severity of fibrosis and steatosis, independently of hepatic and metabolic risk factors. Studies are needed to assess the impact of interventions to reduce sarcopenia on NAFLD progression.

Is early recurrence of hepatocellular carcinoma in HCV cirrhotic patients affected by treatment with direct-acting antivirals? A prospective multicentre study.

BACKGROUND: Data on HCV-related hepatocellular carcinoma (HCC) early recurrence in patients whose HCC was previously cured, and subsequently treated by direct-acting antivirals (DAAs), are equivocal. AIM: To assess the risk of HCC early recurrence after DAAs exposure in a large prospective cohort of HCV-cirrhotic patients with previous successfully treated HCC, also looking for risk factors for cancer early recurrence. METHODS: We enrolled 143 consecutive patients with complete response after curative treatment of HCC, subsequently treated with DAAs and monitored by the web-based RESIST-HCV database. Clinical, biological, and virological data were collected. The primary endpoint was the probability of HCC early recurrence from DAA starting by Kaplan-Meier method. RESULTS: Eighty-six per cent of patients were in Child-Pugh class A and 76% of patients were BCLC A. Almost all patients (96%) achieved sustained virological response. Twenty-four HCC recurrences were observed, with nodular or infiltrative pattern in 83% and 17% of patients, respectively. The 6-, 12- and 18-month HCC recurrence rates were 12%, 26.6% and 29.1%, respectively. Main tumour size and history of prior HCC recurrence were independent risk factors for HCC recurrence by Cox multivariate model. CONCLUSIONS: Probability of HCC early recurrence in patients who had HCC previously cured remains high, despite HCV eradication by DAAs. Risk was comparable but not higher to that reported in literature in DAA-untreated patients. Previous HCC recurrence and tumour size can be used to stratify the risk of HCC early recurrence. Further studies are needed to assess impact of DAAs on late recurrence and mortality.

Fracture risk reduction during treatment with teriparatide is independent of pretreatment bone turnover.

INTRODUCTION: Teriparatide is a bone formation agent that increases bone turnover and mass, resulting in an increase in bone strength and a decrease in fracture risk. METHODS: The primary purpose of this analysis was to evaluate the association between pretreatment bone turnover marker (BTM) concentrations and the absolute and relative fracture risks after adjusting for baseline femoral neck BMD, number of prevalent vertebral fractures, and age. Because femoral neck BMD is commonly attained in the assessment of patients at risk for osteoporosis, we examined the ability of a multivariate assessment including pretreatment BTM concentration and femoral neck BMD to predict future fracture risk after adjusting for the number of prevalent vertebral fractures. We examined data from the Fracture Prevention Trial, a study designed to determine the effect of teriparatide 20 mcg/day and teriparatide 40 mcg/day on vertebral and nonvertebral fracture risk in postmenopausal women with osteoporosis. BTM were analyzed in two subsets of women within the Fracture Prevention Trial, and included serum bone-specific alkaline phosphatase (BSAP), serum carboxy-terminal extension peptide of procollagen type I (PICP), serum amino-terminal extension peptide of procollagen type I (PINP), urinary free deoxypyridinoline (DPD), and urinary N-terminal telopeptide (NTX). RESULTS: Teriparatide significantly reduced the risk of fracture [four BTM subset (n = 520), placebo = 14.3%, teriparatide = 5.8%, P < 0.05; PINP subset (n = 771), placebo = 17.7%, teriparatide = 5.5%, P < 0.05]. Subjects with the highest pretreatment BTM concentrations had the greatest fracture risk. Teriparatide-mediated absolute risk reduction was greatest for women with high pretreatment bone turnover; however, the relative fracture risk reduction was independent of pretreatment bone turnover. After adjusting for pretreatment BTM and number of prevalent vertebral fractures, baseline femoral neck BMD was not a significant predictor of fracture risk. CONCLUSION: Teriparatide-mediated relative fracture risk reduction was independent of pretreatment bone turnover, demonstrating that this therapy offers clinical benefit to patients across a range of disease severity.

Jaw complications associated with bisphosphonate use in patients with plasma cell dyscrasias.

Osteonecrosis of the jaw has been linked with bisphosphonate use in breast cancer and multiple myeloma patients. We report 17 cases of patients with plasma cell dyscrasia being treated with bisphosphonate who developed osteonecrosis/osteomyelitis of the jaw. Seventeen patients evaluated at our institution between 1998 and 2005 are reported. All were being treated with bisphosphonates for a median of 5 mo prior to the onset of jaw symptoms. Sixteen of the 17 patients are 51 yr or older. None of the patients had been irradiated in the jaw nor had obvious osseous manifestation of multiple myeloma in the jaw. Thirteen patients were receiving zoledronic acid and four patients were receiving pamidronate at the onset of jaw symptoms. Six of the 17 did receive both agents at some time and all of these individuals were receiving zoledronic acid at diagnosis. Microorganisms were isolated in 7/17 patients with the most common organism being actinomycosis. We have initiated the following guidelines in an effort to ameliorate the incidence of this complication. Patients should have a full dental examination at the time of diagnosis of the plasma cell dyscrasia especially if bisphosphonates are to be considered as part of the therapy. In addition, bisphosphonates are held for a period of 3 mo prior to invasive dental procedures to allow for the osteoclastic recovery, therefore enhanced debris removal and lessening the chance of creating a fertile bacterial medium. Following the dental procedure we would re-introduce bisphosphonates only after the healing process is complete. Finally, multiple myeloma patients diagnosed with jaw osteonecrosis probably have a concurrent infection and should be aggressively treated with antibiotics.

Effects of prostaglandin E1 on the metabolism in rat parathyroid gland in vitro.

We investigated some effects of prostaglandin E1 on the metabolism of rat parathyroid glands using a culture system containing basal Eagle's medium supplemented with 5--10% heat-inactivated rat serum. Rat parathyroid glands incorporate [3H]fucose and 14C-labeled amino acids into cellular glycoproteins and secrete some of these into the culture medium. Gel filtration chromatography separates these glycoproteins into three classes, the smallest of which (peak 3) is secreted with immunoreactive parathyroid hormone. In cultures of 48 h, prostaglandin E1 (1 microgram/ml) specifically inhibits the secretion of peak 3 and of parathyroid hormone but has no effect on the incorporation of [3H]fucose, 14C-labeled amino acids, or [3H]uridine into parathyroid glands. Cytochalasin B inhibits the secretion of parathyroid hormone and the incorporation of isotopic fucose and amino acids. Cortisol stimulates incorporation of [3H]fucose and the secretion of parathyroid hormone even in the presence of inhibitory doses of prostaglandin E1. It is concluded that, in organ culture, prostaglandin E1 inhibits the secretion of parathyroid hormone and of a specific glycoprotein the function of which may be related to the secretion of the hormone.

Left ventricular filling abnormalities and obesity-associated hypertension: relationship with overproduction of circulating transforming growth factor beta1.

This study has been designed to evaluate the relationship among transforming growth factor beta1 (TGFbeta1) and some measurements of diastolic function in a population of hypertensive subjects with normal left ventricular ejection fraction. We studied 67 hypertensive outpatients who according to their BMI levels were subdivided into three groups: lean (L), overweight (OW) and obese (OB) hypertensives (HT). Circulating TGFbeta1 and M- and B-mode echocardiography was determined. All hypertensives were further subgrouped, according to European Society of Cardiology Guidelines, into two subsets of patients with normal diastolic function or with diastolic dysfunction. Prevalence of left ventricular hypertrophy (LVH) was determined in all the groups. TGFbeta1, left ventricular mass (LVM), LVM/h(2.7), E-wave deceleration time and isovolumic relaxation time (IVRT) were significantly (P < 0.005) higher and E/A velocity ratio was significantly (P < 0.05) lower in OW-HT and OB-HT than in L-HT. Prevalence of LVH was significantly higher (P < 0.03) in group OB-HT than in L-HT. TGFbeta1 (P < 0.004), LVM/h(2.7) (P < 0.001) and prevalence of LVH were (P < 0.01) significantly higher in hypertensives with diastolic dysfunction than hypertensives with normal diastolic function. TGFbeta1 levels were positively correlated with BMI (r = 0.60; P < 0.0001), LVM/h(2.7) (r = 0.28; P < 0.03), IVRT (r = 0.30; P < 0.02) and negatively with E/A ratio (r = -0.38; P < 0.002) in all HT. Multiple regression analysis indicated that TGFbeta1, BMI and IVRT were independently related to E/A ratio explaining 71% of its variability (r = 0.84; P < 0.0001). This relationship was independent of LVH, age and HR suggesting that TGFbeta1 overproduction may be considered a pathophysiological mechanism in the development of left ventricular filling abnormalities in obesity-associated hypertension.

Acute polymyositis during treatment of acute hepatitis C with pegylated interferon alpha-2b.

Hepatitis C virus is not cleared after primary infection in 50-85% of subjects exposed to hepatitis C virus. Anti-viral treatment during the early phase of infection significantly enhances the likelihood of a sustained clearance of hepatitis C virus. Although, a variety of autoimmune-related side effects have been observed during interferon therapy for chronic hepatitis, immuno-mediated adverse reactions have not been reported during treatment of acute hepatitis C. We describe the case of a patient who developed acute hepatitis C virus infection and, while receiving pegylated interferon alpha-2b monotherapy, developed a severe polymyositis. This case illustrates the potential risk of autoimmunity by interferon, also for acute hepatitis, and underlines the importance of a prompt diagnosis and a rapid discontinuation of interferon treatment for an improvement of clinical outcomes.

Symmetrical bone scan in a patient with acute hypercalcemia.

A previously healthy 49-year-old woman had symptoms of acute hypercalcemia that was not parathyroid-hormone mediated. Despite no clinical signs or symptoms of arthritis, a bone scan showed increased uptake in the juxtaarticular areas of the joints in the upper and lower extremities. The biopsy specimen of skeletal lesions noted on roentgenograms supported a diagnosis of multiple myeloma. Symmetrical lesions on bone scan in a patient with asymptomatic joints and acute hypercalcemia may be the first sign of an underlying hematologic malignant neoplasm.

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.

Anal GIST in older old patient: a case report.

UNLABELLED: GIST are a group of quite rare neoplastic pathologies. This type of pathology is currently the subject of discussion as for their origin and treatment. It is generally difficult to determine if they are to be considered as a benign or malignant neoplastic disease. We present the case of a patient with recurrence of anal GIST who was examined 8 years after the first treatment. CASE REPORT: C.M., female, 81 years old, came to our Clinic in March 2001 complaining of rectal haemorrhage and abdominal pain in the lower quadrants; she had also suffered from constipation for 1 month. During rectal exploration we found a mass spreading inside the lumen 3 cm from the anal verge. Colonoscopy showed that the tumour, which was 7 x 5 cm in size, was inside the wall with normal mucosa. EUS revealed that the origin was within the muscular layer; therefore we chose transanal excision as surgical treatment. The patient was discharged 5 days after surgery and is alive; she only showed a small local recurrence of disease 30 months after treatment. Histological examination confirmed that the tumour was a GIST This case provides the basis for a discussion about characteristics and the evolution of this group of pathologies.

[Alcohol sclerotherapy of biliary cysts. Our experience]. / Traitement par alcoolisation des kystes biliaires. Expérience personnelle sur 13 cases.

AIM OF THE STUDY: To evaluate if percutaneous ethanol injection treatment, introduced twelve years ago as palliative therapy for inoperable hepatocellular carcinoma, can be used with curative intent to treat biliary cysts with good results. MATERIALS AND METHODS: For the study were observed 13 symptomatic patients (M 4; F 9 - age 38-71, medium 54 years). All the patients were treated by percutaneous alcoholization under ultrasonographic control. RESULTS: Better technique and protocol standardisation give us the possibility to utilise percutaneous ethanol injection like a good treatment for symptomatic patients. CONCLUSIONS: Easy technique, low cost and very small number of complications gives to percutaneous ethanol injection the possibility to become the gold standard for the treatment of biliary cysts.

[Non recurrent laryngeal nerve. Personal experience]. / Il nervo ricorrente che non ricorre. Esperienza personale.

PURPOSE: Damage to the recurrent laryngeal nerve (RLN) during thyroid or parathyroid surgery is the most common iatrogenic cause of vocal cord paralysis. Identification of the RLNs and meticulous surgical technique can significantly decrease the incidence of this complication. Nonrecurrent RLNs (NRRLNs) are exceedingly rare. Surgeons need to be aware of their position to avoid injuries. PATIENT AND METHODS: A retrospective review of 263 right RLN exposures (and 251 left RNL) over a 5-year period was performed. RESULTS: Two NRRLNs were encountered, for an incidence of 0.39% (0.76% only for right dissection), without anatomic anomalies on the left side. The nerve anomaly was never preoperatively diagnosed. CONCLUSION: NRRLNs are rare and is associated with a right subclavian artery arising from distal aortic arch. Awareness of their existence and correct surgical technique will prevent the surgeon from accidentally lesion of NRRLN one if it is encountered during thyroid or parathyroid surgery.
