Growth hormone status in morbidly obese subjects and correlation with body composition.

Morbidly obese subjects are characterized by multiple endocrine abnormalities and these are paralleled by unfavorable changes in body composition. In obese individuals, either 24-h spontaneous or stimulated GH secretion is impaired without an organic pituitary disease and the severity of the secretory defect is proportional to the degree of obesity. The GHRH+arginine (GHRH+ARG) test is likely to be the overall test of choice in clinical practice to differentiate GH deficiency (GHD) patients. Similarly to other provocative tests, GHRH+ARG is influenced by obesity per se. Therefore, a new cut-off limit of peak GH response of 4.2 microg/l in obese subjects has been recently assumed. The aim of the present study was to investigate the reciprocal influence between decreased GH secretion and body composition in a group of 110 morbidly obese subjects, using the new cut-off limit of peak GH response to GHRH+ARG test for these subjects. In our study, GHD was identified in 27.3% of the obese subjects, without gender difference. In GDH obese subjects body mass index (BMI), waist circumference, waist-to-hip ratio (WHR), fat mass (FM), and resistance (R) were higher while reactance (Xc), phase angle, body cell mass (BCM), IGF-I, or IGF-I z-scores were lower than in normal responders (p<0.001). In all obese subjects, GH peak levels showed a negative correlation with age, BMI, waist circumference and FM, and a positive correlation with IGF-I. In the stepwise multiple linear regression, waist circumference and FM were the major determinants of GH peak levels and IGF-I. In conclusion, using the new cut-off limit of peak GH response to GHRH+ARG test for obese subjects, about 1/3 morbidly obese subjects were GHD. GHD subjects showed a significantly different body composition compared with normal responders, and the secretory defect was correlated to different anthropometric variables with waist circumference and FM as the major determinants.

Stapled haemorrhoidopexy in fourth degree haemorrhoidal prolapse: is it worthwhile?

INTRODUCTION: Ten years after the introduction of stapled haemorrhoidopexy few studies have stratified patients by degree of haemorrhoidal disease when analysing results. Objective The aim of this study was prospectively to evaluate 116 patients who underwent stapled anopexy conducted by the same surgeon for III or IV degree haemorrhoidal prolapse. MATERIALS AND METHODS: One hundred and sixteen consecutive patients affected by symptomatic haemorrhoids of III or IV degree underwent stapled anopexy using the technique described by Longo in the period January 2001 to October 2003. Mean follow-up was 28.1 months. Fischer's exact test was used for statistical analysis. Results, in terms of morbidity and recurrence rates, were stratified according to degree of haemorrhoidal disease. RESULTS: There was no statistically significant difference between the results for third degree compared with fourth degree prolapse although there was a trend towards increased incidence of postoperative bleeding and recurrence. CONCLUSION: Third degree haemorrhoidal prolapse remains the best indication for stapled haemorrhoidopexy. This procedure may also be indicated in fourth degree haemorrhoidal prolapse. Patients with fourth degree haemorrhoids may be subjected to this procedure following adequate discussion of the outcome.

Role of dehydroepiandrosterone sulfate levels on body composition after laparoscopic adjustable gastric banding in pre-menopausal morbidly obese women.

UNLABELLED: In humans, dehydroepiandrosterone (DHEAS) has been postulated to have anabolic and lipolytic properties that could potentially counteract the catabolic effect of cortisol. DHEAS secretion is reduced in morbid obesity, likely due to hyperinsulinemia, and laparoscopic adjustable gastric banding (LASGB), by inducing considerable and rapid weight loss, reduces insulin levels. To investigate the role of decreased insulin levels after LASGB-induced weight loss on DHEAS levels and on body composition changes, we studied 30 pre-menopausal morbidly obese women (BMI ranging 37-62 kg/m2) before, 6, 12 and 24 months after LASGB. Total body water (TBW), fat-free mass (FFM) and fat mass (FM) were measured by bioelectrical impedance analysis; tissue hydration was also assessed by impedance vector analysis. At study ending, the subjects had a total weight loss of 28% of baseline body weight (15% after 6 months). After LASGB, weight loss was mainly due to decreased FM, and TBW, FFM, and body hydration were not significantly reduced. Weight loss was associated with an 82% rise in serum DHEAS already after 6 months while cortisol, cortisol/DHEAS molar ratio, and insulin levels fell by 5.5, 62 and 50%, respectively, after 6, 12 and 24 months (p<0.05). CONCLUSIONS: LASGB associated with a well balanced low-calorie diet permits a satisfactory 2-yr weight loss, sparing FFM and without body fluid alterations. As the result of a stable weight reduction program weight loss is associated to decrease in cortisol, cortisol/DHEAS molar ratio, and insulin plasma levels with marked rise in DHEAS. Higher cortisol/DHEAS molar ratio values at baseline are also associated to lower weight loss after LASGB, with lower decrease in FM and higher reduction in FFM and body cell mass, in spite of no differences in dietary regimes. Cortisol/DHEAS molar ratio is likely to represent a reliable marker of favourable modifications in body composition.

Adrenal adenoma and normal androgen levels in a young woman with polycystic ovaries: a case of idiopathic hirsutism?

A case of unusual combination of polycystic ovaries (PCO), adrenal non-functioning adenoma and severe hirsutism in a young woman from Southern Italy is reported here. A 18-yr-old woman was referred to our Department because of oligomenhorrea, acne and severe hirsutism. During evaluation of the cause of her symptoms, PCO and small left adrenal adenoma were revealed. Although adrenal androgen excess has been shown to dysregulate the hypothalamic-pituitary-gonadal axis, causing PCO-like syndrome, normal circulating androgen values were found. Androgens and cortisol levels were completely suppressed by low-dose dexamethasone test, excluding autonomous steroid secretion by the adrenal mass. Normal response of cortisol and adrenal androgens to corticotropin stimulation test permitted the exclusion of functional adrenal hyperandrogenism. Despite normal LH/FSH ratio, anovulatory cycles were revealed by persistently low progesterone values. Glucose and insulin response to oral glucose tolerance test did not differ from those of normal population. The patient showed an improvement of acne and hirsutism on therapy with estro-progestins (EP). In conclusion, despite normal pattern of serum androgens and LH/FSH ratio, this patient had anovulatory cycles and good response to the EP treatment. These findings suggest that ultrasonography evidence of PCO together with anovulatory cycles contributed to her clinical picture whereas adrenal adenoma seemed to have no relevant role. This case report underlines the need of cautious interpretation of imaging results and clinical signs of severe hirsutism, reminding one that the true cause of a medical problem may not be the most evident.

Screening a coastal population in Southern Italy: iodine deficiency and prevalence of goitre, nutritional aspects and cardiovascular risk factors.

BACKGROUND AND AIM: To evaluate the prevalence of goitre by means of urinary iodine excretion, palpatory and ultrasonographic thyroid examinations in a heterogeneous population living by the sea. METHODS AND RESULTS: We used a special self-administered questionnaire to evaluate thyroid size, iodine intake, eating habits and cardiovascular risk factors in 600 subjects with a mean age of 45 +/- 17 years: 253 men (42.3%) and 347 women (57.7%). Urinary iodine excretion was low (72.1 +/- 15.7 microg/L; median 71.2) and associated with ultrasonographic evidence of an enlarged thyroid (16%) or structural thyroid abnormalities (30%), thus allowing us to define the Salerno Gulf as a mild-moderate area of endemic goitre. All of the subjects ate a Mediterranean diet, with a mean of two portions of fish/week. The cardiovascular risk factors considered were obesity, cigarette smoking, hypertension, hypercholesterolemia, hypertriglyceridemia and diabetes, the prevalences of which were in line with those reported in other studies of similar age-matched populations. CONCLUSIONS: The moderate intake of fish and the consumption of a Mediterranean diet did not prevent goitre. Iodine deficiency and subsequent goitre endemia are also present at sea level, probably because of a diet based on local products grown on soil with a low iodine content or possible seawater, soil and air environmental pollution that may interfere with the availability of iodine. The assessment of iodine deficiency should therefore involve the entire population and not only subjects living far from the sea.

Laparoscopic treatment of post-hysterectomy colovaginal fistula in diverticular disease. Case report.

Colonic diverticular disease is a benign condition typical of the Western world, but it is not rare for even the 1st episode of diverticulitis to carry potentially fatal complications. The evolution of a peridiverticular process generally poses problems for medical treatment and exposes patients to repeated episodes of diverticulitis, making surgical treatment necessary in approximately 30% of symptomatic patients. One of the most worrying complications of diverticulosis is internal fistula. The most common types of fistula are colovesical and colovaginal, against which the uterus can act as an important protective factor. The symptoms and the clinical and instrumental management of patients with diverticular fistulas are much the same as for patients with episodes of acute diverticulitis. Staging of the disease (according to Hinchey) should be done promptly so that the necessary action can be taken prior to surgery, implementing total parenteral nutrition (TPN), nasogastric aspiration and broad-spectrum antibiotic treatment. The best surgical approach to adopt in patients with diverticulitis complicated by fistula is still not entirely clear, though the 3-step strategy is currently tending to be abandoned due to its high morbidity and mortality rates. There is a widespread conviction, however, that the 2-step strategy (Hartmann, or resection with protective stomy) and the 1-step alternative should be reserved, respectively, for patients in Hinchey stages 3, 4 and 1, 2 with a situation of attenuated local inflammation. The 1-step approach seems to be safe and effective. This report describes a case of colovaginal fistula in a patient with colonic diverticulosis who had recently undergone hysterectomy, but who, unlike such cases in the past, was treated in a single step using a laparoscopic technique.

GH release after GHRH plus arginine administration in obese and overweight women with polycystic ovary syndrome.

Few and unclear data are available in the literature about the relationship between impairment of GH/IGF-I axis and polycystic ovary syndrome (PCOS). This study was aimed to evaluate the basal GH and IGF- levels, and GH release after challenge test in obese and overweight women with PCOS. Thirty patients with PCOS and other 30 healthy women matched for age, body mass index (BMI) and waist-hip ratio (WHR) were studied. Serum follicle-stimulating hormone (FSH), LH, PRL, E2, P, 17OH-progesterone (17OH-P), total T, delta4, DHEA-S, SHBG, GH and IGF-I levels were evaluated in each subject. A GHRH plus arginine challenge test was performed in all subjects. After provocative test, in PCOS and control women the GH levels were significantly (p<0.05) higher in comparison to basal values from 30 min to 120 min. At the same times, a significant (p<0.05) difference was observed between women with PCOS in comparison to healthy women. The mean peak value of GH resulted significantly (p<0.05) lower in PCOS women in comparison to healthy women. The total GH response (area under curve, AUC) to GHRH plus arginine test resulted significantly (p<0.05) lower in PCOS than in healthy women. These findings were statistically significant (p<0.05) also considering the distinction in obese and overweight women. The AUC for GH secretion was significantly lower (p<0.05) in obese in comparison to overweight subjects in the control group, whereas no significant difference was detected between obese and overweight women in the PCOS group. In conclusion, in PCOS women there is a BMI-independent alteration of the GH levels. Further investigations will be necessary to establish the real cause of these data.

Early carotid atherosclerosis in normotensive severe obese premenopausal women with low DHEA(S).

The aim of this study was to investigate the direct involvement of hyperinsulinaemia, DHEA and DHEA-S [DHEA(S)] in severe obesity in early carotid atherosclerosis, measured as intima-media thickness (IMT). Seventeen normotensive premenopausal women with very high BMI (43.5 +/- 1.6 kg/m2) were recruited for the study. Six women were also evaluated 12 months after laparoscopic adjustable silicone gastric banding (LASGB). Dietary intake, fasting plasma lipid profile, glycemic and insulinemic response to the OGTT, adrenal secretion, at baseline and after ACTH stimulation test, were measured. IMT, common carotid diameter (CD) and left ventricular mass index (LVMi) were measured by B-mode echotomography. All obese subjects showed higher fasting and stimulated insulin levels, but lower DHEA(S) levels than controls, showing a negative correlation between both fasting and stimulated insulin and DHEA(S), either at baseline or after ACTH testing. IMT was higher (p < 0.05) than controls, with a positive correlation with stimulated insulin (p < 0.05) and a strong negative correlation with DHEA(S) (p < 0.001). In a multiple linear regression analysis, insulin response to OGTT maintained an association with DHEA(S) independent of fasting insulin, while DHEA maintained the association with IMT independent of stimulated insulin (p < 0.0001). In the six patients evaluated 12 months after LASGB, fasting insulin levels decreased, while DHEA(S) levels increased (p < 0.05). In conclusion, an early cardiovascular involvement was detected in this group of severe obese with hyperinsulinaemia and low DHEA(S), even in the absence of other well known CVD risk factors.

[Longitudinal study on osteoarthritis and bone metabolism].

OBJECTIVE: The relationship between Osteoarthritis (OA) and Osteoporosis (OP) is not well defined due to lacking in longitudinal data, mainly regarding correlations between biochemical factors and OA incidence. Aim of this paper was to investigate the predictive value for OA incidence of bone mass variations and of selected biochemical markers in healthy women participating in a population-based longitudinal study carried out in Naples (Italy). SUBJECTS AND METHODS: High completion rate (85.2%) and statistically adequate sample size were obtained: 139 women (45 to 79 years of age) were examined and follow up visit was performed after two years (24+/-2 months), following the same protocol. Patients underwent medical examination, questionnaire, anthropometric measurements, blood sampling and urine collection. Bone mineral density (BMD) measurement was performed by dual energy X-ray absorptiometry (DEXA) at the lumbar spine (L1-L4) and femoral neck. Radiographs of dorsal and lumbar spine in lateral view were performed at basal and at 24 months visits; a team of three experts scored radiographs using Kellgren and Lawrence grading. RESULTS: The score was calculated for two individual radiographic features (narrowing of the joint space, presence of osteophytes) and as a global score. Results show a relevant percentage, 23% up, of subjects presenting both OA and OP. In the cross-sectional study the presence of osteophytosis correlates with anthropometric variables and PTH levels. In the longitudinal study results show a correlation between serum vitamin D and delta score for osteophytosis (beta=0.02 p<0.05). CONCLUSIONS: Data obtained outline the importance of further studies on the pathogenetic link between OA and bone metabolism.

[Topical anesthesia for cataract surgery with phacoemulsification: lidocaine 2% vs ropivacaine 1%. Preliminary results].

BACKGROUND: The safety, tolerability and efficacy of ropivacaine 1% vs lidocaine 2% for phacoemulsification using topical anesthesia during cataract surgery, are compared. METHODS: A prospective, randomized, double-blind study comparing two agents for topical anesthesia is reported. ENVIRONMENT: Operative Unit of Ophthalmology, general Hospital. 1893 consecutively patients were studied (ASA 1-3, 738 males, 1155 females, age 71.8+/-9.7 years, range 35-90 years) undergoing routine phacoemulsification under topical 2% lidocaine (group I) and 1% ropivacaine (group II). The mains outcome measures of the study were: - the total dose of local anesthetic for obtaining a reduction of corneal sensation measured with the Cochet-Bonnet esthesiometer (value>3); - the pain recorded with visual analogic scale and verbal scale at: T1 = the first injection of local anesthetic; T2 = corneal incision; T3 = the end of surgery; T4 = 1h after surgery; T5 = the first postoperative day; - any requirement for additional intraoperative injection anesthesia and systemic sedation when needed; - surgeon assessments of operative conditions and patient cooperation; - patients' subjective level of comfort; - complications. RESULTS: Topical anesthesia using lidocaine 2% was significantly more painful than the ropivacaine 1%. The onset of anesthesia adequate for surgery was similar in all two groups. There were differences between the groups with respect to perioperative analgesia because the VAS was significantly higher in lidocaine group than in ropivacaine group. There were no statistically differences between the two groups at the follow-up. Inadequate anesthesia was seen in 8.05% (74/919 patients) cases of group I vs 0.9% (22/974 patients) of group II. Sedation was needed only in 10 patients and 6 patients of group I and II respectively. The surgeon assessment showed more patient cooperation in the ropivacaine group (83%). Satisfactory comfort (level 1) was reported by 60.4% in the lidocaine group and 86.8% in the ropivacaine group. In both groups there were cases of postoperative epithelial edema (29 patients in group I vs 36 patients in group II) although it decreased after the first postoperative day. No other significant side-effects were observed with the use of either formulations. CONCLUSIONS: Lidocaine 2% and ropivacaine 1% were safe and effective agents in patients having phacoemulsification with IOL implantation. However, ropivacaine provides more good operative conditions than lidocaine for the surgeon and comfortable surgical circumstances for the patient.

Treatment of Kasabach-Merritt syndrome by embolisation of a giant liver hemangioma.

We report the case of a 14-month-old child with Kasabach-Merritt Syndrome, due to a giant liver hemangioma. The therapeutic approach consisted of peripheral transcatheter embolisation of the right hepatic artery with Ivalon microspheres without the addition of thrombogenic material. This procedure brought to a sensible permanent reduction of the size of the liver hemangioma with normalisation of the previous altered coagulation parameters after 6 years of follow-up.

The influence of intense ballet training on trabecular bone mass, hormone status, and gonadotropin structure in young women.

A cross-sectional study on young dancers and exdancers was performed to evaluate the effects of intense weight-bearing exercise and dietary restriction, started during puberty, on bone mineral density (BMD), menarche age, menstrual function, and gonadotropin structure. Twenty current dancers (group 1) and 9 exdancers (group 2) were compared with a control group of 30 age-matched, regularly cycling women. Body weight, body mass index, total daily caloric intake, and nutritional markers were significantly lower (P < 0.05) in groups 1 and 2 than in controls. Using Quantitative Computed Tomography for the BMD evaluation, 12 dancers and 5 exdancers had Z-scores less than 2.5 SD below the mean of the controls; whereas, in 6 dancers and in 2 exdancers, BMD was between 1 and 2.5 SD. Groups 1 and 2 had a delay of menarche, which correlated positively with years of dance before menarche (r = 0.8; P < 0.001). Dancers had low levels and altered structure of circulating gonadotropins, which improved after GnRH stimulation. In conclusion, ballet training performed by dancers during puberty, dietary restriction, and low body mass index can all be associated with reduction in BMD and altered gonadotropin isoforms, with subsequent delay of menarche, menstrual dysfunctions, and insufficient peak bone mass. A longitudinal study must be conducted to confirm the persistence of low lumbar spine bone density in adult age.

Female pseudohermaphroditism and inefficient peak bone mass in an untreated subject affected by 21-hydroxylase congenital adrenal hyperplasia.

Here we describe a subject with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-CAH), in its classical virilizing form, who presented at birth ambiguous genitalia and subsequently was assigned by the parents as male. At the age of 8 years, he underwent a two-step surgical correction of hypospadia and at 22 years old, uterus and ovaries were removed and a bilateral testicular prothesis was surgically placed in scrotum. He refused any chronic glucocorticoid therapy, that was given only acutely to prevent adrenal crises during stress, trauma surgery or severe illness. The patient is now 38 years old, he is genotypically female but phenotypically male, with high endogenous levels of androgen, all of adrenal origin, and with an apparent male sexual life. He had severe osteopenia, probably due to the lack of estrogen/androgen-induced increase in bone mineral density, although periferal estrogen conversion was normal. His skeletal mass, in fact, normally acquired during adolescence and early adult life, could in this case be inefficient, for the precocious pseudopuberty, that caused an inefficient peak bone mass in adolescence period.

[A resources-activities analysis in cardiology: a report on Piemonte experience. The Cardiology Network of the Piemonte Section of the Associazione Nazionale Medici Cardiologi Ospedalieri].

We are living in an era characterized by cost-containment. Thus, expenditure for the health system represents one of the most important items of the national balance. Nowadays, the optimal management of health organization is essential. In addition, patients expect hospitals to provide more and more effective and efficient cures. With respect to this need, in order to achieve high standard of health cure, the identification of work and the time that the medical departments dedicate to a specific therapeutic and/or diagnostic procedure represent a fundamental tool for the optimal management of patients. However, to provide reliable results, these data should be collected in the largest number of structures possible. For this purpose, 17 departments of cardiology have organized a network with the goal of creating the most important data base on this matter available in Italy. The evaluation of the data obtained (more than 8000 medical procedures) allows us to identify the resources normally used for curing patients admitted to cardiological departments. These provide an extensive view of the work load in the Public Health Services fundamental to implementing a health service in accordance with the criteria of Total Quality Management. The present paper illustrates the scope of this study and the methods used to create the data base. In addition, it discusses some cultural aspects related to the introduction of managerial criteria in the medical arena. The detailed results, regarding the items analyzed, will be presented in a special paper.

Unusual association of thyroiditis, Addison's disease, ovarian failure and celiac disease in a young woman.

The coexistence of autoimmune endocrine diseases, particularly autoimmune thyroid disease and celiac disease (CD), has recently been reported. We here present a 23-year-old woman with a diagnosis of hypothyroidism due to Hashimoto's thyroiditis, autoimmune Addison's disease, and kariotypically normal spontaneous premature ovarian failure. Considering the close association between autoimmune diseases and CD, we decided to search for IgA anti-endomysium antibodies (EmA) in the serum. The positivity of EmA and the presence of total villous atrophy at jejunal biopsy allowed the diagnosis of CD. On a gluten-free diet the patient showed a marked clinical improvement accompanied, over a 3-month period, by a progressive decrease in the need for thyroid and adrenal replacement therapies. After 6 months, serum EmA became negative and after 12 months a new jejunal biopsy showed complete mucosal recovery. After 18 months on gluten-free diet, the anti-thyroid antibodies titre decreased significantly, and we could discontinue thyroid substitutive therapy. This case emphasizes the association between autoimmune polyglandular disease and CD; the precocious identification of these cases is clinically relevant not only for the high risk of complications (e.g. lymphoma) inherent to untreated CD, but also because CD is one of the causes for the failure of substitute hormonal therapy in patients with autoimmune thyroid disease.

AlphaANP, AVP, and pituitary-thyroid axis in patients with congestive heart failure and acute respiratory failure.

The pituitary-thyroid axis and neurohumoral activation indexes were simultaneously investigated in 16 in-patients hospitalized for cardiac heart failure (CHF), New York Heart Association (NYHA), class II-IV, and Killip clinical scale, class II-III, to evaluate their relationship with CHF morbidity and the relative prognostic value. At entry the patients were divided into two subgroups (A and B), according to the severity of CHF. Patients were further classified into two subgroups, according to the subsequent clinical course (C, poor outcome and D, improved clinical course). Blood samples were obtained every day for the radioimmunoassay measurement of plasma alpha-atrial natriuretic peptide (alphaANP), arginine vasopressin (AVP), and thyroid hormones, and the results were compared with those of 12 control subjects. At admission, alphaANP and 3,3',5'-triiodothyronine (rT3) values were higher, while 3,3',5-triiodothyronine (T3) to rT3 (T3/rT3) ratio was lower in subgroups A and B than in controls (p<0.001), respectively, and in C than in D (p<0.001), respectively, according to the prognosis. Conversely, no differences in other thyroid indexes, nor a significant correlation between alphaANP and either rT3 or T3/rT3 ratio were present in any of the subgroups. AVP plasma levels in subgroup A were not statistically different from those of controls, whereas they were significantly decreased in subgroups B and C (p<0.05) and D (p<0.001). In conclusion, these results indicate that in CHF the pituitary-thyroid axis is not altered, that alphaANP and T3/rT3 ratio are non-invasive and reliable predictors of severity and prognosis, while AVP might be affected by the different pathological processes leading to CHF or by the concomitant use of drugs.

Transcatheter arterial chemoembolization for hepatocellular carcinoma in patients with Child's grade A or B cirrhosis: a multivariate analysis of prognostic factors.

We evaluated factors affecting long-term survival after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) complicating cirrhosis. One hundred eighty-two patients with Child's class A or B cirrhosis and an HCC, not amenable to surgery or percutaneous ethanol injection, underwent 346 TACEs (mean 1.9) with epirubicin, iodized oil, and gelatin sponge. Many prognostic factors were subjected to univariate analysis and thereafter, when significant, to the Cox's hazard proportional model. Finally, the significant indices in the Cox's model were used to estimate the accuracy of the probability of death with computation of the area under the receiving operative characteristic (ROC) curve. The cumulative survival rates at 1, 2, 3, and 5 years were 0.83, 0.52, 0.40, and 0.16, respectively. According to Cox's model, the factors associated with significantly worse survival were the presence of ascites (p = 0.0027), elevated bilirubin levels (p = 0.0163), elevated alpha-fetoprotein (alphaFP) values (p = 0.0067), a tumor greater than 5 cm in diameter (p = 0.0001), and the absence of a tumor capsule-like rim (p = 0.0278). According to these parameters, the accuracy of the probability of death estimated with ROC analysis was 0.63. Minor and major complications occurred in 82 patients (45%) and caused death in 2 patients. Long-term prognosis after TACE for HCCs in patients with Child's class A or B cirrhosis depends on the presence of ascites, the bilirubin level, the alphaFP value, the diameter of the tumor, and the presence of a tumor capsule-like rim. However, when considered altogether, these variables are poor predictors to evaluate survival, and other factors should be investigated to identify subjects more responsive to TACE. Complications occur in a high percentage of patients, but they do not affect long-term prognosis.

Prevalence of coeliac disease in patients with thyroid autoimmunity.

The occurrence of autoimmune thyroid disorders among patients with coeliac disease (CD) is well documented, but the exact prevalence of CD among patients with autoimmune thyroid diseases (ATD) is as yet unclear. We screened 150 newly diagnosed patients with ATD by serum endomysial antibody detection (EmA). In 5 subjects (3.3%) EmA positivity was found; all underwent jejunal biopsy. On gluten-free diet an excellent clinical and histological response was recorded with an improvement of hypothyroidism and reduction of the thyroxine dosage. Our data suggest a significant high prevalence (3.3%) of CD in patients with ATD, in particular with Hashimoto's thyroiditis.
