Abstract
OBJECTIVE Hepatitis E Virus (HEV) is probably the most common cause of acute hepatitis worldwide. It has been regarded for a long time as a disease limited to developing countries. Recently, the refinement of diagnostic techniques, on the one hand, and migratory flows, on the other hand, have also led to the identification of an increased number of HEV infections in industrialized countries. Four HEV genotypes have been identified across the world, with different epidemiological burdens and a wide range of clinical presentations. Here, we report a case series of acute HEV hepatitis observed in the last three years in our hospital. PATIENTS AND METHODS We performed a search for HEV IgM and IgG in all subjects admitted for acute hepatitis without evidence of other possible infectious, toxic or metabolic causes of liver damage. In subjects with HEV IgM positivity, the search for HEV-RNA was performed. RESULTS We diagnosed eight acute HEV infections: 2 epidemic and 6 sporadic forms. HEV-RNA was detected in serum in 2 cases. CONCLUSIONS HEV infection appears to be a cause of acute hepatitis that we must keep in mind even in developed countries.

Abstract
BACKGROUND Alcohol abuse represents the most common cause of liver disease in the Western countries. Pre-clinical and clinical studies showed that alcohol consumption affects amount and composition of gut microbiota. Moreover, gut flora plays an important role in the pathogenesis of alcoholic liver injury. AIM To review the relationship between alcohol administration and changes on gut microbiota, its involvement in the pathogenesis of alcoholic liver disease, and how gut microbiota modulation could be a target for the treatment of alcoholic liver disease. METHODS Articles were identified using the PubMed database with the search terms 'Alcohol', 'Gut Microbiota', 'Alcoholic liver disease', 'Probiotic', 'Prebiotic', 'Symbiotic' and 'Antibiotic'. English-language articles were screened for relevance. Full review of publications for the relevant studies was conducted, including additional publications that were identified from individual article reference lists. RESULTS Alcohol abuse induces changes in the composition of gut microbiota, although the exact mechanism for this alteration is not well known. The translocation of bacterial products into the portal blood appears to play a key role in alcohol-induced liver damage. Several studies show that the modulation of gut microbiota seem to be a promising strategy to reduce alcohol-induced liver injury. CONCLUSIONS Further studies are needed to better understand the relationship between alcohol administration and changes in gut microbiota, and its involvement in alcoholic liver disease. Moreover larger studies are needed to confirm the preliminary results on the therapeutic effects of gut microbiota modulation.

Abstract
INTRODUCTION Traumatic brain injury (TBI) is the leading cause of death and acquired disability in childhood. Research has demonstrated that TBI can lead to long-term physical, cognitive, emotional and behavioural difficulties for children and parental stress. Less is known about how parents experience a childhood brain injury and their information and support needs. This study aimed to examine parents' experiences and support needs following a childhood TBI from the time of the accident to their child's discharge home. METHODS Qualitative semi-structured interviews were conducted with 29 parents/carers of children who had experienced a severe TBI. Participants were recruited from one children's tertiary centre in the UK. Data were analysed using the Framework approach. RESULTS Parents had unmet information and emotional support needs across the care trajectory from the time of the accident to their child's return home. Information needs related to the impact of the TBI on their child; current and future treatment/rehabilitation plans; helping their child and managing their behaviour; accessing services/support. They lacked information and support for care transitions. In different settings parents faced particular barriers to having their information needs met. Parents' felt they needed emotional support in coming to terms with witnessing the accident and the loss of their former child. Lack of community support related not only to service availability but to a general lack of understanding of the impact of TBI on children, particularly when this was invisible. Overall parents felt unsupported in coping with children's behavioural and psychological difficulties. DISCUSSION Taking a holistic approach to examining parents' experiences and support needs has enabled their changing needs to be highlighted across key care transitions within hospital and community settings and the service implications identified. Improvements in care co-ordination across care transitions are needed to ensure continuity of care and integration of support.

Abstract
OBJECTIVES C1q deficiency is a rare inherited defect in the early part of the complement cascade. In this report, we describe the varied clinical features of patients with this condition as well as the characteristic autoantibody profile. METHODS A large Pakistani family with a high degree of consanguinity is described in which the father and five sons have C1q deficiency, all with different clinical manifestations. RESULTS Clinical features of C1q deficiency can vary from almost no disease to fulminant bacterial infection and localized lupus-like skin, renal or CNS disease. Autoantibodies to ribonucleoproteins such as anti-Sm and Ro, but not dsDNA, were present. CONCLUSIONS Awareness of the spectrum of clinical disease, autoantibody profiles and tests required to confirm the diagnosis of C1q deficiency are important if this life-threatening immunodeficiency disease is to be managed correctly.

Abstract
BACKGROUND AND OBJECTIVES The lymphohistiocytic (LH) variant of anaplastic large cell lymphoma (ALCL) has, for a long time, been considered typical of children and adolescents. The aim of this study is a detailed characterization of a case of this peculiar ALCL subtype affecting an adult patient. DESIGN AND METHODS A 36-year old male presented with diffuse adenopathy and systemic symptoms (high fever, anorexia, asthenia); a diagnosis of CD30+/ALK+ ALCL, LH variant, was morphologically suspected and corroborated by immunohistochemistry that was crucial for the definitive diagnosis and subtyping. RESULTS The neoplastic population consisted of cells highly variable in size and shape but more often isolated and largely obscured by a predominant reactive cellular infiltrate of histiocytes and plasma cells. The lymphoma cells exhibited a null non-B non-T antigenic profile, but reacted strongly for the Ber-H2/CD30, EMA, ALKc anti-TIA-1 monoclonal antibodies. The patient underwent chemotherapy plus bone marrow transplantation and, one year after diagnosis, he is well and in complete remission. INTERPRETATION AND CONCLUSIONS Our findings provide additional evidence that: a) ALK+ lymphoma represents a single disease with a broad spectrum of morphology; b) clinicians and pathologists should be aware of the possible occurrence of LH variant of ALK+ ALCL also in adults in whom a favorable response to therapy may be expected despite systemic disease and an aggressive clinical presentation.

Abstract
BACKGROUND Thoracic computed tomography (CT) provides most of the staging information needed before operation for lung cancer and can reduce the number of exploratory thoracotomies. In recent years a new immunoscintigraphic technique with anti-carcinoembryonic antigen (CEA) monoclonal antibodies has been shown to be effective in lung cancer staging. This study compares the yields of CT scans and immunoscintigraphy in the preoperative evaluation of the medistinal lymph nodes of patients with non-small cell lung cancer. METHODS One hundred and thirty one patients believed on clinical grounds to have a operable non-small cell lung cancer were photoscanned with the indium-111 labelled F(ab')2 fragments of the antibody FO23C5. Both planar and single photoemission computed tomography (SPECT) thoracic views were recorded. CT scan of the thorax, abdomen, and brain were obtained in all patients. Seventy of the patients eventually underwent surgery, an additional seven underwent mediastinoscopy or mediastinotomy, and a further 10 had both cervical exploration and thoracotomy. Pathological evaluation of the mediastinal nodes was available in all 87 patients, but in only 80 of them was the diagnosis of lung cancer eventually confirmed. RESULTS The diagnostic accuracy of planar immunoscintigraphy, SPECT immunoscintigraphy, and CT scanning for N2 disease was 76%, 74%, and 71%, respectively. The corresponding sensitivity and specificity rates were 45%, 77%, 64% and 88%, 72%, and 74%. These were not significantly different. CONCLUSIONS This study shows that anti-CEA immunoscintigraphy has no advantage over conventional CT scanning in assessing mediastinal lymphoadenopathy in patients with lung cancer. CT scanning remains the gold standard test in these patients.

Abstract
Giant cell tumors of the temporal bone are very rare lesions. They should be differentiated from other giant cell lesions of bone, mainly reparative granulomas. A case with a very huge giant cell tumor of the temporal bone extending to the infratemporal fossa, temporomandibular joint, and greater wing of the sphenoid has been presented. Because of their tendency for recurrence, total removal is the treatment of choice for these tumors and was accomplished through the infratemporal fossa approach type B. A follow-up of 2 years and 9 months revealed no evidence of tumor recurrence.

Abstract
A case of full-thickness necrosis of the small bowel, and colon, which required partial resection of the jejunum and total resection of the ileum and colon is reported. The case gives the chance for a review of the Literature on intestinal necrosis not caused by vascular occlusion. Nonocclusive intestinal ischemia, acute neonatal necrotizing enterocolitis and adult necrotizing enterocolitis including the Pig-bel disease, common in Papua-New Guinea, are examined. Resemblances and differences in etiology, pathophysiology and clinical findings are discussed. The hypothesis that the process of "bacterial translocation" plays a central role in the pathogenesis of bowel infarction, representing therefore a possible link between infective and vascular mechanisms, is emphasized. Important suggestions on massive intestinal necrosis management are also reported.

Abstract
BACKGROUND Anticarcinoembryonic (CEA) monoclonal antibodies are able to react specifically with the antigen and have the potential for the detection of CEA-bearing tumors. METHODS The authors photoscanned with indium 111 (111In)-labeled F(ab')2 fragments of the murine CEA monoclonal antibody FO23C5 63 patients with a newly diagnosed and pathologically documented bronchogenic carcinoma. Planar dual views of the thorax, abdomen, and brain were acquired between the 24th and 144th hour after the radiotracer injection. Patients had a complete pretreatment workup, which included a routine multiorgan computed tomography (CT) scan, and the determination of the serum and tissue CEA concentration. All patients were followed up clinically and radiologically. Nineteen needle aspirations and biopsies, 23 surgical explorations, and 4 mediastinoscopic studies yielded 121 pathologically documented sites of reference. RESULTS Fifty-seven of 63 scans were positive for the primary tumor (sensitivity, 0.90). The uptake of the radiotracer correlated significantly with the intensity of tissue CEA expression (Spearman R [Rs], 0.25; P less than 0.05), but not with the serum CEA level or with the histotype. Overall, the sensitivity of the anti-CEA immunoscintigraphy (IS) for the N1, N2, N3, T3, T4, and M1 disease (1987 International Union Against Cancer [UICC] staging classification) was 0.67, 0.64, 0.62, 0.31, 0.29, and 0.86, respectively. Corresponding values of specificity were 0.67, 0.81, 0.90, 1, 1, and 0.93; accuracy values were 0.67, 0.71, 0.85, 0.71, 0.76, and 0.92. The authors limited the analysis to all of the pathologically documented sites and obtained slightly superior values but no meaningful differences. The stage derived from IS readings was correct in 33 patients. The same figure was obtained after an initial clinical workup, which included physical examination, laboratory routine tests, chest radiographs, bronchoscopy, and any diagnostic procedure indicated by those tests. CONCLUSIONS Anti-CEA FO23C5-F(ab')2 fragments are not yet "magic bullets" for perfect diagnoses; however, their staging potential seems to be remarkable. Technical improvements, single-photo emission CT, and the use of such fragments in combination with other imaging techniques might enable researchers to further improve the current results.

Abstract
Several clinical and epidemiological evidences support the increased risk of cardiovascular disease (CVD) in pathological conditions as obesity, hypertension, non-insulin-dependent diabetes mellitus, which have hyperinsulinemia as a common feature. In this study, we assessed basal plasma insulin (IRI) and C-peptide (CPR) concentrations in 297 volunteers who participated in a survey concerning risk factors of CVD. We found a stepwise increase in fasting insulin and C-peptide levels in normal subjects (IRI 9.10 +/- 0.41 microU/ml; CPR 1.79 +/- 0.08 ng/ml), in obese subjects (IRI 11.31 +/- 0.38 microU/ml; CPR 2.54 +/- 0.07 ng/ml) in obese hypertensive subjects (IRI 14.17 +/- 0.72 microU/ml; CPR 2.64 +/- 0.09 ng/ml), in obese hypertensive diabetic subjects (IRI 22.57 +/- 2.62 microU/ml; CPR 3.33 +/- 0.27 ng/ml). Thus, we found increasing levels of IRI and CPR as normal conditions changed towards progressively more severe pathological conditions. Although several other factors contribute to determine CVD, we conclude that increasing levels of insulin and C-peptide could play an important role in causing CVD.

Abstract
We report a case of metastatic thymic neoplasm occurring in a 62-year-old Caucasian man. The tumor was polymorphic, with intimately admixed carcinoid, sarcomatous and undifferentiated components. Sarcomatous cells were spindle-shaped and immunoreactive for vimentin, actin and desmin. Carcinoid cells reacted for cytokeratin as well as with a panel of general neuroendocrine markers, including chromogranins A and B, synaptophysin, protein gene product (PGP) 9.5, neuron specific enolase (NSE), Leu 7 and Grimelius' silver. The endocrine nature of the latter cells was confirmed by ultrastructural evidence of abundant electron-dense granules 100 to 300 nm in size. Among the various hormones investigated immunohistochemically only the alpha chain of human chorionic gonadotropin (alpha-hCG) was detected in tumor cells. The neoplasm recurred after surgical resection and caused a typical carcinoid syndrome with skin flushing and increased urinary 5-hydroxyindolacetic acid (5-HIAA). The diagnosis of multidirectional thymic carcinoma with two lines of differentiation, of carcinoid and sarcomatoid type, was made.

We examined biopsy and autopsy specimens of 32 patients treated with regular haemodialysis for 61 +/- 34 months. All patients received dextran-40 as a plasma expander because of hypotension during haemodialysis. The same study was carried out in a control group of 11 haemodialysed patients who were given other plasma expanders. In the 11 patients who received larger doses of dextran-40 (0.38 g/kg body weight per week) we found particles in the cytoplasm of macrophages in various organs, which proved PAS positive and diastase resistant on light microscopy, and birefringent on polarisation. Electron microscopy revealed a fibrillar structure, but ionic analysis by electronic sampler on scanning electron microscopy excluded the presence of silicon. No intracellular inclusions were observed in the control group, nor in the patients given dextran-40 in doses lower than 0.08 g/kg body weight per week. As we also found a linear relationship between the number of particles and the dextran-40 doses given, we hypothesise that the material demonstrated in the macrophages is a structurally modified dextran.

Abstract
An unusual case of multiple relapsing Spitz nevus (SN) in a patient with pseudohypoparathyroidism is described. It arose initially as a single lesion, and recurred twice as multiple agminated lesions that maintained the same histological pattern as the original SN. Nevertheless, the clinical behavior led to a diagnosis of metastasis from malignant melanoma at another medical institution. This case emphasizes the need for relying on accurate histopathological criteria to distinguish SN from malignant melanoma if inappropriate and detrimental therapeutic procedures are to be avoided.
