The incidence of genitourological diseases is greater that that of circulatory disorders, benign prostate hyperplasia (BPH) is the commonest urological disease in the elderly and senile males. According to the results of the authors' clinicomorphological study, BPH has been detectable in 69% of the males who died at the age of above 60 years. BPH frequently occurs in patients with arterial hypertension, diabetes mellitus, coronary heart disease, and metabolic syndrome, which necessitates a search for the commonness of causes or mechanisms of development of these diseases. The most important complication of BPH is acute urinary retention. Its major causes in therapeutic clinic are recurrent chronic prostatitis, decompensation of circulatory insufficiency, and emergencies generally resulting from alcohol abuse. As this takes place, the worst prognosis is observed in elderly patients with the complicated comorbid status, particularly in the presence of chronic alcohol intoxication. Patients with BPH are at high and surgical treatment-unassociated risks for pulmonary arterial thromboembolism (PATE). In these patients, the causes of PATE are pelvic deep vein thromboses whose incidence in clinical practice is underestimated.

Although chronic liver disease has many etiologies, including chronic viral hepatitis, alcohol abuse, metabolic syndrome, and autoimmune disorders, the cellular and pathological mechanisms leading to hepatic fibrosis and - as an end-stage - cirrhosis are relatively common and uniform. Liver fibrosis is characterized by an accumulation of extracellular matrix proteins, and activated hepatic stellate cells (HSC), portal fibroblasts and myofibroblasts have been identified as major collagen-producing cells in the injured liver. Experimental models of liver fibrosis highlight the importance of hepatic macrophages, so-called Kupffer cells, for perpetuating an inflammatory phase resulting in the massive release of proinflammatory cytokines and chemokines as well as activation of HSC. Recent studies demonstrate that these actions are only partially conducted by liver-resident macrophages, but largely depend on recruitment of monocytes into the liver, namely of the inflammatory Gr1+ (Ly6C+) monocyte subset as precursors of tissue macrophages. The chemokine receptor CCR2 and its ligand MCP-1/CCL2 participate in regulating monocyte subset infiltration. Macrophages, on the other hand, display a remarkable plasticity and can differentiate into functionally diverse subtypes, e.g. 'classically activated' M1 and 'alternatively activated' M2 macrophages. Experimental animal models indicate that monocytes/macrophages are not only critical for fibrosis progression, but also for fibrosis regression, because macrophages can also degrade extracellular matrix proteins and exert anti-inflammatory actions. The recently identified cellular and molecular pathways for monocyte subset recruitment, macrophage differentiation and interactions with other hepatic cell types in the injured liver may therefore represent interesting novel targets for future therapeutic approaches in liver fibrosis.

Several studies have demonstrated that the outcome of chronic hepatitis C (CHC) infection is profoundly influenced by a variety of comorbidities. Many of these comorbidities have a significant influence on the response to antiviral therapy. These comorbidities negatively affect the course and outcome of liver disease, often reducing the chance of achieving a sustained virological response with PEGylated interferon and ribavirin treatments. Comorbidities affecting response to antiviral therapy reduce compliance and adherence to inadequate doses of therapy. The most important comorbidities affecting the course of CHC include hepatitis B virus coinfection, metabolic syndrome, and intestinal bacterial overgrowth. Comorbidities affecting the course and response to therapy include schistosomiasis, iron overload, alcohol abuse, and excessive smoking. Comorbidities affecting response to antiviral therapy include depression, anemia, cardiovascular disease, and renal failure.

We report the evidence-based Italian Association for the Study of Liver guidelines for the appropriate diagnosis and management of patients with nonalcoholic fatty liver disease in clinical practice and its related research agenda. The prevalence of nonalcoholic fatty liver disease varies according to age, gender and ethnicity. In the general population, the prevalence of nonalcoholic fatty liver disease is about 25% and the incidence is of two new cases/100 people/year. 2-3% of individuals in the general population will suffer from nonalcoholic steatohepatitis. Uncomplicated steatosis will usually follow a benign course. Individuals with nonalcoholic steatohepatitis, however, have a reduced life expectancy, mainly owing to vascular diseases and liver-related causes. Moreover, steatosis has deleterious effects on the natural history of HCV infection. Nonalcoholic fatty liver disease is usually diagnosed in asymptomatic patients prompted by the occasional discovery of increased liver enzymes and/or of ultrasonographic steatosis. Medical history, complete physical examination, etiologic screening of liver injury, liver biochemistry tests, serum lipids and insulin sensitivity tests should be performed in every patient. Occult alcohol abuse should be ruled out. Ultrasonography is the first-line imaging technique. Liver biopsy, the gold standard in diagnosis and prognosis of nonalcoholic fatty liver disease, is an invasive procedure and its results will not influence treatment in most cases but will provide prognostic information. Assessment of fibrosis by composite scores, specific laboratory parameters and transient elastography might reduce the number of nonalcoholic fatty liver disease patients requiring liver biopsy. Dieting and physical training reinforced by behavioural therapy are associated with improved nonalcoholic fatty liver disease. Diabetes and the metabolic syndrome should be ruled out at timed intervals in nonalcoholic fatty liver disease. Nonalcoholic steatohepatitis patients should undergo periodic evaluation of cardiovascular risk and of advancement of their liver disease; those with nonalcoholic steatohepatitis-cirrhosis should be evaluated for early diagnosis of hepatocellular carcinoma.

Psoriasis is a chronic inflammatory disorder that affects approximately 2% of the general population. Numerous studies have evaluated the increased prevalence of comorbid diseases and risk factors in psoriatic patients, including obesity, metabolic syndrome, cardiovascular disease, psoriatic arthritis, autoimmune disease, psychiatric illness, liver disease, smoking, malignancy, chronic obstructive pulmonary disease, sleep apnea, and alcohol abuse. Insight into the overlapping pathogenesis of these comorbidities of psoriasis highlights the importance of immune-mediated mechanisms in these disease states. Psoriasis, with its comorbidities, must be approached in a multidisciplinary manner to effectively and comprehensively understand, manage, and treat those with this complex disorder.

Abstract Alcohol abuse is a major cause of abnormal liver function throughout the world. While measurements of liver enzyme activities (GGT, ALT, AST) are important screening tools for detecting liver disease, due to lack of ethanol-specificity and inconsistencies regarding the definitions of significant alcohol consumption, several other blood tests are usually needed to exclude competing and co-existing causes of abnormal liver function. Information on the specific role of ethanol consumption behind hepatotoxicity may be obtained through measurements of blood ethanol and its specific metabolites (ethyl glucuronide, phosphatidylethanol, protein-acetaldehyde condensates and associated autoimmune responses). Recent studies have indicated that being overweight is another increasingly common cause of abnormal liver enzyme levels and adiposity may also increase the impact of ethanol consumption on liver pathology. Interestingly, increased liver enzyme activities in circulation may reflect not only hepatic function but can also serve as indicators of general health and the status of oxidative stress in vivo. ALT and GGT activities predict insulin resistance, metabolic syndrome, mortality from coronary heart diseases and even mortality from all causes. If the upper reference limits for liver enzyme activities were defined based on the data obtained from normal weight abstainers, the clinical value of liver enzyme measurements as screening tools and in patient follow-up could be significantly improved.

Hepatic lipid droplets (LDs) are associated with metabolic syndrome, type 2 diabetes, hepatitis C, and both alcoholic and nonalcoholic fatty liver disease. MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the level of translation. Approximately 1000 different miRNA species are encoded within the human genome, and many are differentially expressed by healthy and diseased liver. However, few studies have investigated the role of miRNAs in regulating LD expression. Accordingly, a high-content assay (HCA) was performed in which human hepatocytes (Huh-7 cells) were transiently transfected with 327 unique human miRNAs; the cells were then fixed, labeled for nuclei and lipid droplets, and imaged with an automated digital microscopy workstation. LD expression was analyzed on a cell-by-cell basis, using automated image analysis. Eleven miRNAs were identified that altered LDs. MiR-181d was the most efficacious inhibitor, decreasing LDs by about 60%. miRNA-181d was also confirmed to reduce cellular triglycerides and cholesterol ester via biochemical assays. Furthermore, a series of proteins was identified via miRNA target analysis, and siRNAs directed against many of these proteins also modified LDs. Thus, HCA-based screening identified novel miRNA and protein regulators of LDs and cholesterol metabolism that may be relevant to hepatic diseases arising from obesity and alcohol abuse.

Postmenopausal women show the highest incidence of breast cancer in the female population and are often affected by metabolic syndrome. Metabolic syndrome (MS)--characterized by central adiposity, insulin resistance, low serum high-density lipoprotein cholesterol (HDL-C), high serum triglyceride and high blood pressure--seems to be strictly correlated to breast carcinogenesis. We enrolled 777 healthy women and women with breast cancer in our nested case-control study to evaluate the association between MS and breast cancer, analyzing anthropometric parameters (weight, height, BMI, waist and hip circumference), blood pressure, serum HDL-C, triglyceride, fasting plasma glucose, insulin, testosterone and uric acid levels and administering a questionnaire about physical activity, food intake, tobacco use, alcohol abuse, personal and familial history of disease. We found an higher prevalence of metabolic syndrome (30%) in postmenopausal breast cancer patients compared to healthy women (19%). None of the individual MS features was strong enough to be considered responsible for breast carcinogenesis alone. However, of the 63 postmenopausal breast cancer cases associated to MS, 30% presented three or more MS features, suggesting that the activation of multiple molecular pathways underlying MS might contribute to tumorigenesis. Our data support the hypothesis that MS may be an indicator of breast cancer risk in postmenopausal women. The unsettlement of the hormonal arrangement in postmenopausal, along with an increase in visceral adiposity, probably favour the hormone-dependent cell proliferation, which drives tumorigenesis. Adjustments in lifestyle with physical activity intensification and healthy diet could represent modifiable factors for the primary prevention of sporadic breast cancer.

In opposition to opinions of a sectorialization of psychiatric illness, phenomena of comorbidity due to susceptibility of psychiatric patients to contract other diseases--whose co-presence is difficult to translate and treat--are more and more evident. In this review we have marked main issues of internal medicine in psychiatric patients. This review will discuss particularly main cardiovascular diseases (CAD, VTE), lung diseases (COPD,asthma, restrictive lung disease) gastroenterologic disease (IBS, coeliac disease, ulcerous rectocolitis), diabetes and metabolic syndrome, more likely infections verified in these patients (HIV, viral hepatitis), cancers considerably underlined (breast cancer, colon-rectal cancer and lung cancer), internistic issues in alcohol abuse which is a frequent state in these subjects. A special chapter is dedicated to antipsychotics. These drugs are characterized by a complex action modality and by frequent interactions with a large number of other drugs.

Nonalcoholic fatty liver disease (NAFLD) is a disease in which excessive fat accumulates in the liver of a patient without a history of alcohol abuse. This disease includes simple steatosis and nonalcoholic steatohepatitis (NASH). NAFLD/NASH is recognized as a hepatic manifestation of metabolic syndrome. In recent years, pediatric NAFLD has increased in line with the increased prevalence of pediatric obesity. The estimated prevalence of pediatric NAFLD is 2.6%-9.6%, and it is associated with sex, age, and ethnicity. With regard to the pathogenesis of NAFLD, the "two-hit" hypothesis is widely accepted and oxidative stress is thought to play an important role in the second hit. Although clinical symptoms, laboratory data, and imaging findings are important, liver biopsy is regarded as the gold standard for the diagnosis of NAFLD/NASH. In addition, liver biopsy is essential for assessing the degree of necro-inflammatory change and fibrosis in NASH. Two different types of steatohepatitis (type 1 and type 2 NASH) have been reported, with type 2 NASH being present in as many as 51% of pediatric NAFLD patients. However, we and others have observed that type 1 and 2 patterns commonly overlap. Although pharmacotherapy has been studied in clinical trials, lifestyle modification by diet and exercise remains the mainstay of treatment for NAFLD/NASH.
