A case of Jarcho-Levin Syndrome is described which is characterized by severe costo-vertebrate anomalies. In our case signal severe cardiopathy.
We report a case of one boy with Niemann-Pick disease (type C). The manifestations are delayed but the clinical evolution is swift.
We reported a case of Prader-Willi Syndrome. The simple chromosomic mapping is negative. The obesity and polifagye is not present (2 years old). The ipotony is improving, this case belongs to a possible light case.
We described the case of a newborn, whose mother was affected by anti-phospholipids antibodies syndrome and had previously had several abortions. The newborn presented emispondilitis. (We suppose it is important to notice that cases like this have never been signalled in literature so far).
We described the case of a thirteen years old boy who came to our observation because of ematuria, orbital oedema, headache and hypertension (with renal symptoms). In few hours this syndrome evolved in a serious hypertensive encephalopathia with convulsions and emiparesis.
A physical-chemical characterisation of several marbles frequently used in ancient times for artistic or decorative purposes was performed in support the work of historians and restorers. The data were obtained using several different types of instrumental chemical methods (Thermogravimetry, Differential Thermal Analysis, X-ray Diffractometry and ICP Plasma Emission Spectroscopy) and have been summarised in short tables. The data have already proved useful in the identification of a small number of finds (statues or architectonic elements) from Ancient Rome (Imperial Age, 2nd-3nd cent. A.D.) for the purpose of which also a well-known pattern recognition analysis software package was used for data processing. In practice, the research showed that an organised set of chemical data obtained using several modern instrumental methods can provide a valid basis for the reasonably rapid and reliable identification of the type of marble used to make artistic artifacts that have not yet been subjected to typological study.
OLT in HIV infected patients still remains a challenging option requiring a careful monitoring of patients for HCV reinfection, drug interactions and antiretroviral toxicity. Severe adverse events due to HAART have been already reported for post exposure prophylaxis in HIV infected patients. Here we report a case of liver graft toxicity related to HAART in a HIV-HCV co-infected patient (46 yrs-male) with associated a small HCC transplanted with a marginal liver graft. The patient had pre-OLT plasma HIV 1-RNA levels undetectable and CD4+ T-cell count of > 200 cells/microL for 6 months. At day 2 a severe graft dysfunction was observed (AST 1570 U/L, ALT 2180 U/L, BIL tot 8.3 mg/dL, BIL Dir 6.6 mg/dL and PT 35%--INR 2.5). Doppler scan showed hepatic artery always patient. Later the postoperative in-hospital course was complicated by tense ascites and severe cholestasis. Serum bilirubin reached 42 mg/dL in day 12. Hypertransaminasemia ended at day 15 while cholestasis ended after 46 days. Tacrolimus was reintroduced at day 7. A liver biopsy 10 after OLT showed severe intrahepatic cholestasis, centrolobular necrosis and macrovesicular steatosis (30%). The patient was discharged 48 days after OLT with good liver function. After seven months HIV-RNA is still undetectable and HAART has not been restarted. We believe that the early complications we observed may be attributed to a sudden increase in plasma concentration of antiretroviral drugs secondary to drug redistribution from peripheral tissues and hepatic clearance deficiency after OLT. Although a pre-OLT withdrawal of HAART seems unjustified a delayed re-introduction of HAART or the use of less hepatotoxic drugs may be advisable.

Interactions between HPA (Hypothalamic-pituitary-axis) and immune system seem to involve the EPO (endogenous opioid peptides) system, as shown by some recent findings. Possible relationships between beta-endorphin (beta-End) synthesis and severity rate of immunodeficiency have been studied in 48 HIV Ab positive patients, at different stages of infection. A statistically significant decrease in the beta-End synthesis was observed in these patients, as compared to a control group of 19 healthy subjects, but this decrease was not related to the CD4+T lymphocytes number. Plasmatic levels modifications of HPA-related peptides were not observed in the IVC1 CDC group.
