Abstract
INTRODUCTION Cellular analysis in cerebrospinal fluid (CSF) provides important diagnostic information in many pathological settings. The aim of this two-site study was to evaluate the Sysmex XN Body Fluid mode (XN-BF) for cell analysis of CSF compared to light microscopy (LM). METHODS Two hundred and seven consecutive CSF samples were analyzed in parallel with XN-BF and LM. The study also included the estimation of the limit of blank (LoB), limit of detection (LoD), limit of quantitation (LoQ), carry-over and linearity of XN-BF module. RESULTS LoQ of white blood cells (WBC) was 3×106 cells/L; linearity was good and carry-over negligible. XN-BF parameters were compared to LM for the following cell classes: total cells, WBC, polymorphonuclear (PMN), and mononuclear (MN) cells. The bias ranged from 1.3 to 15.2×106 cells/L. The receiver operating characteristics curve analysis for WBC showed an area under the curve of 0.98, and the global diagnostic agreement was 95% at a cutoff of 5×106 cells/L. CONCLUSIONS XN-BF provides rapid and accurate counts in clinically relevant ranges of CSF values, thus providing a valuable alternative to conventional LM analysis. However, microscopic review remains advisable in samples with abnormal cell counts or high fluorescent (HF-BF) cell parameter exceeding 5×106 cells/L.

Abstract
BACKGROUND Previous studies have demonstrated that serum anti-actin antibodies are a reliable marker of intestinal damage severity in coeliac disease. AIMS To validate in a multicentre study the clinical usefulness of serum IgA anti-actin antibody ELISA and its possible use in monitoring intestinal mucosa lesions during gluten-free diet. PATIENTS AND METHODS Four centres recruited 205 newly diagnosed coeliac disease patients with villous atrophy, 80 healthy controls and 81 "disease" controls. Twelve coeliac disease patients on gluten-free diet but with persistent symptoms underwent serum IgA anti-actin antibody assay and intestinal histology evaluation. IgA anti-actin antibody ELISA was performed with a commercial kit. All coeliac disease patients underwent intestinal histology study. RESULTS IgA anti-actin antibodies showed a sensitivity of 80% and a specificity of 85% in the diagnosis of coeliac disease patients with villous atrophy. The area under the receiving operator curve for anti-actin antibodies was 0.873 [95% C.I. 0.805-0.899]. Serum anti-actin antibodies values were significantly higher in coeliac disease patients than in healthy or "disease" controls (P<0.0001). Serum anti-actin antibodies were positive in 41 of the 60 coeliac disease patients with mild intestinal histology lesions (69%) and in 123 of the 145 with severe lesions (85.3%) (P<0.05). There was a significant inverse correlation between anti-actin antibody values and the villi/crypts ratio (r=-0.423; P<0.0001). In the 12 coeliac disease patients on gluten-free diet who underwent re-evaluation as they were persistently symptomatic, intestinal histology showed three cases with persistent villous atrophy: all of these were positive for serum anti-actin antibodies ELISA, whereas both serum anti-tTG and EmAs were negative. The other nine patients showed normal intestinal villi and were negative for serum anti-actin antibodies. CONCLUSIONS Anti-actin antibodies are a reliable marker of severe intestinal mucosa damage in coeliac disease patients and a simple ELISA technique offers an accurate method for their determination. These antibodies seem to be a very reliable marker of persistent intestinal damage in coeliac disease patients.

Abstract
997 strains isolated from clinical specimens arrived at the "Pio Albergo Trivulzio" microbiology laboratory were tested using disks of cefpodoxime, amoxicillin + clavulanic acid, cefaclor, cefuroxime, ofloxacin, cotrimoxazole, ceftriaxone and cefalexin. Gram-positive strains were tested also with erythromycin, while gram-negative bacteria were tested against aztreonam. Cefpodoxime overall activity was well above the effectiveness of the other oral cephalosporins and on the same order as ceftriaxone and ofloxacin. Cefpodoxime proved to be also more active than the combination amoxicillin-clavulanic acid.

Abstract
In a series of 438 subjects (184 normolipidemics and 254 hyperlipidemics) the relationship among serum concentration of triglycerides, lipoprotein lipids and apoproteins A-I and B has been evaluated. The results show that as serum triglyceride level increases, VLDL rise and become enriched in triglycerides. The increase of VLDL is associated with a reduction of serum levels of LDL and HDL which appear to be rich in triglycerides and poor in cholesterol. The decrease in serum HDL level is mainly due to a reduction in serum concentration of the HDL2 subfraction. The triglyceride content of HDL2 and HDL3 rises with increasing serum triglycerides. The increase in serum triglyceride concentration seems then to be associated with a complex metabolic derangement which involves all the lipoprotein fractions.

Abstract
We used monoclonal antibodies of the OK series to study T lymphocyte subpopulations in 55 patients with monoclonal gammapathy of undetermined significance (MGUS) and in 40 healthy control subjects, with the aim to investigate if alterations in T lymphocyte subpopulations occur also in MGUS. Mean OKT3+ and OKT8+ cell counts were higher (p less than 0.01 and p less than 0.001, respectively) and the mean OKT4/OKT8 ratio was lower (p less than 0.02) in MGUS patients than in the control subjects. MGUS with the IgM-type monoclonal immunoglobulin (IgM-MGUS) showed the most evident derangement of T lymphocyte subpopulations, i.e., a significant increase of OKT8+ cells and a significant reduction of the OKT4/OKT8 ratio. OKT4+ and OKT8+ cells were significantly increased in patients with high paraprotein concentration (above 16 g/l). Our data suggest that alterations of T lymphocytes are present in MGUS, and that they are similar to those observed in malignant lymphoproliferative disorders.

Abstract
In 72 obese women body mass index positively correlated with age and both showed multiple correlations with serum lipids and lipoprotein lipids. After adjustment for age (partial correlation procedure), body mass index resulted to be positively correlated with serum triglycerides, VLDL lipids, HDL-triglycerides and negatively correlated with HDL-cholesterol. The decrease in HDL-cholesterol concentration along with the increase in body weight was due to the reduction of cholesterol in HDL2 subfraction, while HDL3-cholesterol did not show any significant correlation with body mass index. The negative correlation between HDL2-cholesterol and body mass index was independent of other lipoprotein variables and in particular of VLDL lipid levels that were, as expected, inversely related to HDL2-cholesterol. HDL2-cholesterol is believed to be a strong protective factor against atherosclerosis, while doubts exist on the meaning of VLDL lipids as risk factors. Thus, the decrease in HDL2-cholesterol concentration, rather than the increase in VLDL lipids, might give a rational basis to the high incidence rate of vascular disease in obese subjects.

Abstract
The relationship of the degree of metabolic control to the serum lipoprotein pattern has been studied in 62 young insulin treated diabetic patients. Stable HbA1 and 24-h mean blood glucose, but not daily insulin dosage, were positively correlated to VLDL-TG (p less than 0.001) and negatively correlated to HDL2-C (p less than 0.05). HDL2-C was higher in patients with HbA1 less than 10% than in patients with HbA1 greater than 10%. In 13 patients, in whom an improvement of metabolic control was achieved, a significant increase of HDL2-C was recorded after three months. Our data are consistent with the view that in insulin-treated patients, good metabolic control is associated with low VLDL-TG and high HDL2-C levels.

Abstract
Sixteen type IIb and 26 type IIa hyperlipoproteinemic patients were treated with bezafibrate 200 mg t.i.d. After 1 month VLDL-TG decreased by 54% in type IIb and by 43% in type IIa; LDL-C decreased by 13% in type IIb and by 23% in type IIa patients. HDL3-C rose in both group of patients, while HDL2-C significantly increased (52%) only in patients with phenotype IIb. The change in LDL-C and in HDL2-C concentrations resulted to be related to the pretreatment VLDL lipid concentration and to its change during the treatment. Twenty patients were treated with bezafibrate for 4 months. On the average, the changes in lipoprotein lipid concentration attained at the end of the first month of therapy remained substantially constant in the following 3 months.

Abstract
Retrograde coronary sinus perfusion as a means of delivering cardioplegia was evaluated in 20 patients undergoing cardiac valve surgery. Other 10 patients, undergoing similar operation with antegrade coronary cardioplegic perfusion served as a control. Results showed no significant differences between the two groups of patients in terms of: myocardial cooling; pre-ischemic and post-perfusion myocardial lactate extraction; post-operative clinical findings (myocardial infarction occurrence, need for inotropic support, mortality). We conclude that retroperfusion through the coronary sinus is a safe and effective alternative of cardioplegic delivery. Since it simplifies the operative procedure (it allows the cardioplegia delivery at any desired time of the operation, without discontinuing the procedure), we recommended its use during valvular cardiac operations, especially on aortic valve replacement.

Abstract
Twenty five hypertriglyceridaemic patients (16 Type IV and 9 Type IIb) were treated with fenofibrate 300 mg/d. In Type IV patients serum triglycerides and VLDL cholesterol decreased, while LDL and HDL cholesterol rose significantly. In Type IIb patients, triglycerides and total, VLDL, IDL and LDL cholesterol were significantly reduced by the treatment. The correction of hypertriglyceridaemia by fenofibrate seems, therefore, to induce different changes in lipoproteins in Type IIb and in Type IV hyperlipoproteinaemic patients. The practical implications of these results are discussed.
