We present the arterial complications arising from 100 orthotopic liver transplants (OLT) carried out in 87 consecutive patients. Mean patient age was 42.5 +/- 12.8 years (7-63). There was a predominance of male patients (67%). The most common indications were hepatic cirrhosis (53%) and severe acute hepatitis insufficiency (14%). The donor liver presented 29 arterial malformations, mainly a left hepatic artery arising from the left gastric artery, either as a single or associated anomaly. Only six arterial complications appeared in 4 of the 87 patients. Of these six, four corresponded to arterial thrombosis, and the remaining two to arterial stenosis and a ruptured mycotic aortic aneurysm. Two of the 4 patients had a double arterial complication (one had arterial thrombosis in 2 of the 3 grafts, and the other presented arterial thrombosis and aortic rupture). No arterial complications were related to arterial anomalies in the donor liver. Three of the 4 patients died from the complication. The 1-year actuarial survival rate in our series is 77.5%. In conclusion, arterial complications are infrequent in our series (6%) but do carry a high mortality rate (75%).

A retrospective analysis of 3042 autopsies was carried out to determine and compare the discrepancy rates between clinical and autopsy diagnoses as well as the sensitivity and specificity of clinical diagnostics in 10 diseases in 1977/78 and 1987/88. The autopsy rate decreased from 80% to 39%, which might explain the increased discrepancy rate from 22% to 27% regarding the diagnoses of major, principal diseases. The accuracy of clinical diagnostics seemed to improve during the period for some of the diseases (pulmonary embolism, peptic ulcer, infectious carditis, peritonitis), while it worsened for others (acute myocardial infarction, thrombosis of the mesenteric artery, ruptured aortic aneurysm, tuberculosis) or remained unchanged (cirrhosis of the liver, malignant tumours regarded as a whole group). The findings underline the importance of autopsies and their cumulative studies in assessing the accuracy and providing data for the determination of necessary fallibility of clinical diagnostics.

A retrospective analysis was made of 58 patients who unexpectedly developed multiple organ failure (MOF) following elective surgery, and the results were compared with those of 168 control patients who did not develop MOF. In 33 patients with liver cirrhosis, MOF was related to poor liver function, a low albumin level, excessive blood loss, many transfusions, and a high incidence of hypotension. MOF, rather than liver failure alone, was featured by postoperative bleeding and infection. In 15 patients with esophageal carcinoma, MOF was correlated with many transfusions, anastomotic leakage, and postoperative infection. In 10 patients who underwent surgery for an aortic aneurysm, poor renal function and extended anesthesia time were associated with MOF. These results indicate that to prevent MOF following elective surgery, it is important to: (1) Select patients for liver surgery according to their liver function, and minimize the risk of bleeding and infection, (2) avoid too many blood transfusions, and minimize the risk of leakage and infection in esophageal surgery, and (3) select patients for aortic surgery based on renal function and reduce the anesthesia time as much as possible.

Cigarette smoking has been clearly and unambiguously identified as a direct cause of cancers of the oral cavity, oesophagus, stomach, pancreas, larynx, lung, bladder, kidney and leukaemia, especially acute myeloid leukaemia. Additionally, cigarette smoking is a direct cause of ischaemic heart disease (the commonest cause of death in western countries), respiratory heart disease, aortic aneurysm, chronic obstructive lung disease, stroke, pneumonia and cirrhosis and cancer of the liver. Cigarette smoking can kill in 24 different ways and, although smoking protects against several fatal and non-fatal conditions, the adverse effect of smoking on health is largely negative. In developed countries as a whole, tobacco is responsible for 24% of all male deaths and 7% of all female deaths: these figures rise to over 40% in men in some countries of central and eastern Europe and to 17% in women in the United States. The average loss of life of smokers is 8 years. Among United Kingdom doctors followed for 40 years, overall death rates in middle age were about three times higher among doctors who smoked cigarettes as among doctors who had never smoked regularly. About half of all regular cigarette smokers will eventually be killed by their habit. The important information is that it is never too late to stop smoking: among United Kingdom doctors who stopped smoking, even in middle age, there was a substantial improvement in life expectancy. World-wide, smoking is killing three million people each year and this figure is increasing. In most countries the worst is yet to come, since by the time the young smokers of today reach middle or old age there will be about 10 million deaths/year from tobacco. Approximately 500 million individuals alive today can expect to be killed by tobacco, 250 million of these deaths will occur in middle age. Tobacco is already the biggest cause of adult death in developed countries. Over the next few decades tobacco could well become the biggest cause of adult death in the world. For men in developed countries, the full effects of smoking can already be seen. Tobacco now causes one-third of all male deaths in middle age (plus one fifth in old age). Tobacco is a cause of about half of all male cancer deaths in middle age (plus one-third in old age). Of those who start smoking in their teenage years and keep on smoking, about half will be killed by tobacco. Half of these deaths will be in middle age (35-69) and each will lose an average of 20-25 years of non-smoker life expectancy. In non-smokers in many countries, cancer mortality is decreasing slowly and total mortality rapidly. The war against cancer is being won slowly: the effects of cigarette smoking are holding back this victory. Lung cancer now kills more women in the United States each year than breast cancer. For women in developed countries, the peak of the tobacco epidemic has not yet arrived. Tobacco now causes almost one-third of all deaths in women in middle age in the United States. Although it has only 5% of the world's female population, the United States has 50% of the world's deaths from smoking in women. Tobacco smoking is a major cause of premature death. Throughout Europe, in 1990 tobacco smoking caused three quarters of a million deaths in middle age (between 35 and 69). In the Member States of the European Union in 1990 there were over one quarter of a million deaths in middle age directly caused by tobacco smoking: there were 219700 in men and 31900 in women. There were many more deaths caused by tobacco at older ages. In countries of central and eastern Europe, including the former USSR, there were 441200 deaths in middle age in men and 42100 deaths in women. There is a need for urgent action to help contain this important and unnecessary loss of life. In formulating Recommendations, the European Cancer Experts Consensus Committee recognised that Tobacco Control depends on various parts of society and not only on the individual.

Chylothorax and chylascites are rare complications of neoplasm or surgical, but also non-surgical trauma. Extremely rare causes are a subclavian i.v. line, a mesenterical hamartoma, retrosternal goiter, liver cirrhosis, portal vein thrombosis, filariasis, tuberculosis, ruptured aortic aneurysm and radiotherapy. We report on a 60-year-old male with bilateral chylothorax and chylascites resistant to therapy 18 years after irradiation of the iliacal, paraaortal and mediastinal (46 Gray) and the left-sided supraclavicular (40 Gray) lymph nodes for a seminoma (T3N1M0 i.e. IIa, Lugano classification). A fat-free parenteral nutrition was started in order to bring the lymphatic flow down to a minimum. Chyle flow ceased after 3 1/2 weeks of treatment. An oral diet with middle chain triglycerides (MCT-diet), which are transported to the liver via the portal vein instead of the lymphatic system, achieved good control of residual chylous effusions.

Several issues should be addressed when managing women with Turner's syndrome. Female sex hormone substitution should be offered to help prevent the increased morbidity seen in Turner's women, which consists of an increased risk of fractures and osteoporosis, and a clustering of diseases such as ischaemic heart disease, hypertension, stroke and type 2 diabetes, the latter entities being part of the insulin resistance syndrome. Furthermore, hypothyroidism is often seen, and the risk of type 1 diabetes may also be increased. Congenital malformations of the heart are frequently seen in Turner's syndrome, possibly increasing the risk of dissecting aorta aneurysm. Liver enzymes are often elevated and there may be an increased risk of liver cirrhosis. Mortality seems to be increased in Turner's syndrome, women with the "pure" 45,X karyotype being the most severely affected. In clinical practice, careful monitoring of glucose and bone metabolism, weight, thyroid function and blood pressure should be carried out. A cardiovascular risk profile should be determined and the patient informed of the risks and benefits of sex hormone replacement therapy. Sex hormone replacement therapy is highly recommended, although at present there are no longitudinal data documenting the long-term positive effect of sex steroid substitution. However, hypogonadism is expected to explain at least part of the decreased lifespan found in Turner's syndrome. Since general physicians only encounter these patients infrequently, it is recommended that the care and treatment of Turner's syndrome be centralized.

Most hypervascular nodules in a cirrhotic liver are hepatocellular carcinomas (HCCs); however, some are benign hypervascular hyperplastic nodules. We report a case of benign hypervascular hyperplastic nodules in a 41-year-old male patient without hepatitis B or C virus infection, with a history of alcohol abuse, and diagnosed with an aortic aneurysm. The dynamic computerized tomography of the liver demonstrated multiple nodular lesions on both liver lobes with arterial enhancement and delayed washout. The hepatic angiography showed multiple faint nodular staining of both lobes in the early arterial phase. Magnetic resonance imaging revealed numerous nodules showing high signals on T1 weighted images, with some nodules showing a low central signal portion. The clinical impression was HCC. The ultrasonography-guided liver biopsy, which was performed on the largest nodule (2.5 cm in size), revealed hepatocellular nodules with slightly increased cellularity, unpaired arteries, increased sinusoidal capillarization, and focal iron deposition. However, both cellular and cytological atypia were unremarkable. Although the clinical impression was HCC, the pathological diagnosis was hypervascular hyperplastic nodules in alcoholic cirrhosis. Differential diagnosis of hypervascular nodules in cirrhosis and HCC is difficult with imaging studies; thus, histological confirmation is mandatory.

Electrocardiogram (ECG)-triggered, low dose computed tomography (CT) is increasingly used for attenuation correction in myocardial perfusion imaging (MPI) with SPECT. The purpose of the study was to assess the prevalence of relevant noncardiac findings in the field-of-view of such attenuation correction CT scans. Five hundred and eighty-two consecutive patients (211 female, 371 male; mean age: 64 +/- 11 years; BMI: 27.7 +/- 5.3 kg/m(2)) underwent 64-slice, ECG-triggered CT scanning for attenuation correction of MPI with SPECT. Relevant findings were defined as abnormalities that required clinical or radiological follow-up. Noncardiac findings were detected in 400 patients (68.7%). In 196 patients (33.7%) 226 relevant findings were detected. Findings included noncalcified pulmonary nodules (n = 156), interstitial lung disease (n = 6), pleural effusion (n = 20), pneumonia (n = 1), aortic aneurysm (n = 5), aortic dissection (n = 4), enlarged mediastinal lymph nodes (n = 5), mediastinal tumor (n = 3), breast abnormalities (n = 3), liver cirrhosis (n = 5), liver mass (n = 5), ascites (n = 5), splenomegaly (n = 2), renal mass (n = 1), hydronephrosis (n = 1), adrenal mass (n = 3), and bone metastasis (n = 1). As low dose 64-slice CT scans used for attenuation correction in MPI with SPECT reveal a high prevalence of noncardiac pathologic findings with potential clinical relevance, a systematic review of the CT scans appears mandatory.

Matrix metalloproteinases (MMPs) have a great variability that provides a complex intervention in pathophysiological conditions. MMPs roles in pathology may be grouped into the following main types: (1) tissue destruction, as in cancer invasion and metastasis, rheumatoid arthritis, osteoarthritis, different types of ulcers, periodontal disease, brain injury and neuroinflammatory diseases; (2) fibrosis, as in liver cirrhosis, fibrotic lung disease, otosclerosis, atherosclerosis, and multiple sclerosis; (3) weakening of matrix, as in dilated cardiomyopathy, epidermolysis bullosa, aortic aneurysm and restenotic lesions. Recent data also adds new MMPs functions in angiogenesis and apoptosis. Interesting opposite intervention in escaping mechanisms vs. antitumor defensive mechanisms had been also reported. As MMP-7 is expressed by tumor cells of epithelial and mesenchymal origin, it may be used as a biological marker of an aggressive phenotype and as a target of therapeutic intervention. MMPs play a pivotal role in the pathogenesis of arthritis, atherosclerosis, pulmonary emphysema, and endometriosis. Although MMP involvement in pathology is more than simple excessive matrix degradation, or an imbalance between them and their specific tissular inhibitors (TIMPs), MMP inhibition may be of therapeutic benefit, so synthetic MMPs inhibitors had been developed and are currently under clinical testing.

We report a case of successful treatment of a mycotic aneurysm of the thoracic aorta. A 65-year-old man with a dissecting aneurysm presented with urinary tract infection. He had a history of severe liver cirrhosis. Two weeks after admission, he had a high-grade fever and enhanced computed tomography (CT) demonstrated acute expansion of the distal aortic arch aneurysm. Because of the acute aneurysm expansion and elevated inflammatory response, we suspected a mycotic aortic aneurysm with possible impending rupture. Since conventional open chest surgery was considered to carry a high operative risk, the patient was managed with a combination of emergency endovascular treatment and antibiotic chemotherapy. Extended-spectrum beta-lactamase-producing Escherichia coli were identified from blood culture before treatment. After strict antibiotic therapy, the postoperative course was uneventful and the patient remained well 12 months later.
