A clinical audit: diagnostic and epidemiological evaluation of the adrenal incidentaloma.

BACKGROUND: Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The adrenal incidentaloma is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1450,000 patients and 58,000 about them show a surrenalic lesion identified with CT or MRI as Adrenal Incidentaloma. METHODS: Through a search in the radiological archives, were reviewed all abdominal CT performed in the year 2012 in 8 departments of Internal Medicine of 8 Italian public hospitals. They also examined all medical records of these patients to value clinical management of the adrenal masses and the real incidence of the adrenal incidentaloma. RESULTS: Distribution of pathological results show an important incidence about adrenal incidentaloma in Italian patients although this pathology is represented as a rare disease and its clinical and economic burden are significant. Many questions remain unanswered as the association between duration and severity of the disease, morbidity and how the dimensions affecting it. These results need to be supported by important studies with long follow-up to realize an easy diagnosis. CONCLUSIONS: The results of this audit confirm the real incidence of this pathology in the internistic patients and the final target is to implement changes about therapeutic diagnostic pathway of the hospital patients in the internal medicine departments.

Ultrasonographic study of gallbladder wall thickness and emptying in cirrhotic patients without gallstones.

BACKGROUND AND AIM: Gallbladder wall thickening and impaired contractility are currently reported in cirrhotic patients and often related to portal hypertension and hepatic failure. The purpose of this work was to evaluate, by ultrasonographic method, gallbladder wall thickness and gallbladder emptying after a standard meal in normal subjects and in patients with compensated liver cirrhosis without gallstones. METHODS: Twenty-three patients with Child-Pugh class A liver cirrhosis and twenty healthy controls were studied. Gallbladder wall thickness (GWT), gallbladder fasting volume (FV), residual volume (RV), and maximum percentage of emptying (%E) were calculated. Measurements of mean portal velocity, portal vein flow, and serum albumin were performed too. Statistical analysis was assessed by Student's "t test" for unpaired data. RESULTS: GWT was 0.60 +/- 0.22 cm in cirrhotic patients and 0.21 +/- 0.06 cm in controls (P < .0001). FV and RV were, respectively, 37.8 +/- 3.7 cm(3) and 21.8 +/- 3 cm(3) in cirrhotic patients, 21.9 +/- 4.2 cm(3) and 4.6 +/- 2.2 cm(3) in healthy volunteers (P < .0001). %E was smaller in cirrhotics (42.6 +/- 7.8) as compared to controls (80.3 +/- 7.2; P < .0001). CONCLUSIONS: In patients with compensated liver cirrhosis without gallstones gallbladder wall thickness is increased whereas its contractility is reduced. These early structural and functional alterations could play a role in gallstone formation in more advanced stages of the disease.

Donor livers with steatosis are safe to use in hepatitis C virus-positive recipients.

Whether donor graft steatosis affects liver function and influences survival after liver transplantation is still open to debate. The aim of this study was to assess the impact of donor graft steatosis on long-term liver histology after liver transplantation. One hundred sixteen consecutive liver transplants were performed in 56 hepatitis C virus-positive (HCV+) patients and 60 HCV- patients who had protocol liver biopsies at 6, 12, 24, and 36 months after liver transplantation. Liver biopsies were obtained from all grafts. No steatosis was seen in 50.9% of the biopsies taken at the back table before implantation, whereas steatosis was mild in 39.6% of the samples and moderate/severe in 9.5% of the samples. In the 56 HCV+ recipients, fibrosis stage 3 was seen in 22.2% and stage 4 was seen in 2.2% of 45 biopsies at 36 months after liver transplantation. There was no correlation between donor graft steatosis and fibrosis after liver transplantation, regardless of the etiology of liver disease. No difference in 36-month survival after liver transplantation was seen, regardless of whether the etiology of the patient's liver disease was HCV-related or non-HCV-related (80.3% versus 75%; P = 0.4) and whether the steatosis in the graft was reportedly absent, mild, or moderate/severe (79.7% versus 73.9% versus 81.1%; P = 0.7). In conclusion, nearly one-quarter of HCV+ recipients have precirrhosis/cirrhosis 3 years after liver transplantation. Steatotic grafts do not seem to exacerbate the progression of fibrosis in HCV+ recipients, nor do they seem to negatively affect 3-year patient survival.

Different neurological outcome of liver transplantation for Wilson's disease in two homozygotic twins.

Wilson's disease is a genetic disorder characterized by accumulation of copper in many organs and tissues. Phenotypic manifestations are wide-ranging from neuropsychiatric disorders, to severe liver disease requiring liver transplantation. Clinical presentation is not often related to the genetic defect and siblings may have different type of disease. Liver transplantation is indicated for all patients with Wilson's disease and decompensated liver cirrhosis unresponsive to medical therapy, but its efficacy in resolving the neurological symptoms is still controversial, because as far now, very different outcomes have been reported. We describe here on the exceptional case of two homozygotic twins, both with liver cirrhosis due to Wilson's disease, one of them with severe neuropsychiatric involvement, who both underwent liver transplantation and subsequently had very different outcome despite same genetic background. The presence of neurological clinical manifestations in Wilson's disease should recommend caution indicating liver transplantation, because irreversible brain damage may exist.

Radioisotopic assessment of gastric emptying of solids in elderly subjects.

BACKGROUND AND AIMS: Few studies in literature have investigated the gastric emptying of solids in elderly subjects. We assessed the differences between young and elderly subjects in the gastric emptying rate of solids by a radioisotopic method. METHODS: Two groups of 15 elderly male subjects (mean age 68.20 years and 77.26 years, respectively) and a group of young male subjects (mean age 30.23 years) underwent a radioisotopic study of gastric emptying after eating a radiolabeled solid meal. Half-time of gastric emptying (T1/2) and emptying index (EI), i.e. rate of gastric emptying at 120 min, were measured with two opposing detectors connected to a computerized rate-meter. Results are expressed as means +/- SD. RESULTS: Significantly different values were obtained in the two groups both at T1/2 (183+/-88 and 195+/-75, respectively) and EI (0.40+/-0.3 and 0.36+/-0.4), compared with young subjects (T1/2=53+/-23; EI=1.10+/-0.3) (p<0.0001). CONCLUSIONS: Gastric emptying of solids is significantly delayed in elderly men; this variable must be taken into account when studies on gastric emptying rates are performed.

Successful pregnancy in a liver transplant recipient treated with lamivudine for de novo hepatitis B in the graft.

Pregnancy is often successful after liver transplantation, despite the potentially toxic effects of immunosuppressive drug therapy. Liver transplant recipients with recurrent hepatitis C or hepatitis B nonetheless appear to be at risk of a worse graft function in the event of pregnancy, and antiviral drugs are generally contraindicated in pregnancy because of their teratogenic effects. A 33-year-old woman had undergone liver transplantation for Caroli's disease 6 years previously. Two years later the patient experienced de novo HBV hepatitis. Lamivudine treatment (100 mg/day) was started and clearance of HBsAg was documented 1 year later. Four years after starting antiviral treatment the patient became pregnant, despite of the risk of teratogenic effects; lamivudine, cyclosporine and azathioprine were not discontinued for risk of break-through hepatitis and acute or chronic rejection. The course of gestation was uneventful and caesarean section was performed after 36 weeks. The newborn infant was a healthy male weighing 3,080 g and measuring 50 cm.

Pattern of gastric emptying in functional dyspepsia. An ultrasonographic study.

We assessed the ultrasonographic pattern of gastric emptying in patients with functional dyspepsia, evaluating its relationship with symptoms. Twenty dyspeptic patients, with slight (group A) and severe (group B) symptoms, and 10 controls (group C) underwent ultrasonographic study of gastric emptying by measuring postprandial variations of the antral area at regular intervals. The time at which the antral area returned to the basal value was assumed to be the final emptying time. The final emptying time was significantly longer in both group A (294 +/- 42 min) and group B (340 +/- 36 min) compared to controls (244 +/- 21 min), but no significant difference was observed between them. A significantly (P < 0.05) greater dilation of the antral area was found at 50 min in group B compared to group A patients. A different pattern of antral motor function rather than a delay of gastric emptying correlates with the severity of symtoms in dyspeptic patients.

Combined liver-kidney transplantation in a 15-year-old boy with alpha1-antitrypsin deficiency.

Alpha1-antitrypsin (1-AT) deficiency is the most common genetic cause of liver disease in infants and children. The major clinical manifestations include liver disease (primarily in children) and emphysema in adults. For patients who progress to cirrhosis and liver failure, liver transplantation provides a metabolic cure for the deficiency and presumably prevents the associated complications. Several case reports in the pediatric literature describe glomerulonephritis in the setting of severe 1-AT deficiency, but this association is less well documented in adults. End-stage chronic kidney disease is a rare finding in the literature and kidney transplantation is the treatment of choice. We report on a 15-year-old boy with 1-AT deficiency and consequent end-stage liver disease and membranoproliferative glomerulonephritis rapidly progressing to renal failure, who successfully underwent combined liver-kidney transplantation.
