Abstract
Geotrichum capitatum, now known as Blastoschizomyces capitatus, can be responsible for several opportunistic infections (systemic infection or localized at lungs, liver, kidney, encephalitis or meningitis) in an immunocompromised host, especially in those patients affected by leukaemia or under immunosuppressive therapies. A 66-year-old woman with polimyosite under steroid and immunosuppressant therapy was hospitalized in ICU for an acute respiratory distress with moderate hypoxaemia and normocapnia. Pulmonary X-ray revealed a bilateral pneumonia. Hypoxaemia became severe 48 hours later and the patient underwent mechanical ventilation and empirical antibiotic therapy. Blood cultures, urine cultures and serological tests were negative, while yeast was identified by Gram's stain of bronchoaspirate. Before identifying the yeasts Fluconazole was added to therapy. At day 5 the clinical conditions remained severe and Candida spp were excluded: so Fluconazole was switched to liposomal Amphotericin B. At day 8 B. capitatus was identified. At day 26 the patient died of refractory respiratory insufficiency. B. capitatus infection is infrequent and its prognosis is severe, with a high mortality rate (>50%). Microbiological diagnosis requires time to characterize the yeast. At present no standard therapy is available although some authors report a good susceptibility to Amphotericin B and Voriconazole (100%), according to NCCLS guidelines.

Abstract
Allergic reactions to antibiotics are commonly reported. They can be classified as immediate or non-immediate according to the time interval between the last drug administration and their onset. Immediate reactions occur within the first hour and are manifested clinically by urticaria and/or angioedema, rhinitis, bronchospasm, and anaphylactic shock; they may be mediated by specific IgE-antibodies. The main non-immediate reactions (occurring more than one hour after drug administration) are maculopapular exanthems; specific T lymphocytes may be involved in this type of manifestation. The diagnostic evaluation of hypersensitivity reactions to antibiotics is usually complex. The patient's history is fundamental; the allergologic examination includes in vivo and in vitro tests selected on the basis of the clinical features. Prick and intradermal tests are sensitive in evaluating betalactam hypersensitivity. Together with delayed-reading intradermal testing, patch testing is useful in diagnosing maculopapular reactions to systemically administered aminopenicillins. Determination of serum specific IgE is the most common in vitro method for diagnosing immediate reactions, while the lymphocyte transformation test can be performed for evaluating both immediate and non-immediate ones. In selected cases, provocation tests should be performed.

Abstract
OBJECTIVE Down's syndrome (DS) is the most frequent genetic cause of Alzheimer-type dementia. Its metabolic phenotype involves an increased trans-sulphuration of homocysteine. The aim of the present study was to investigate the influence of homocysteinaemia (t-Hcys), folate, vitamin B(12), and related polymorphisms on intelligence quotient (IQ) in DS. METHODS The IQ of 131 patients with trisomy 21 from a specialist centre in Sicily was determined and classified according to DMS-IV. The effects of age, folate, vitamin B(12), t-Hcys, and genetic polymorphisms on IQ were evaluated separately and in combination using regression analyses. RESULTS IQ was significantly lower in DS patients with t-Hcys >7.5 micromol/l (median) and in those who were carriers of methylenetetrahydrofolate reductase (MTHFR) 677 T allele and of methylenetetrahydrofolate reductase 677 T and transcobalamin 776 G combined alleles (p = 0.0013, p = 0.0165, and p = 0.0074, respectively). The IQ correlated significantly with t-Hcys and folate in single and multiple regression analyses, independently of age. In addition, t-Hcys >9.6 micromol/l (upper quartile) was found to be associated with low IQ (<40, median of study group) with an odds ratio of 2.61 (p = 0.0203). The odds ratio was increased by threefold in carriers of MTHFR 677T allele. The MTHFR 677T allele/transcobalamin 776 G allele combination was associated with the risk of DS patients to have an IQ less that the median with an odds ratio of 2.68 (95% CI 1.26 to 5.70, p = 0.0104). CONCLUSION This study found evidence of an association between t-Hcys and MTHFR 677 T and transcobalamin 776 G alleles with IQ in patients with DS. The association may be related to a defective remethylation of homocysteine, affecting IQ.

Abstract
Wolf-Hirschhorn syndrome (WHS) is caused by a variably-sized deletion of chromosome 4 involving band 4p16 whose typical craniofacial features are "Greek warrior helmet appearance" of the nose, microcephaly, and prominent glabella. Almost all patients show mental retardation and pre- and post-natal growth delay. Patient was born at term, after a pregnancy characterized by intra-uterine growth retardation (IUGR). Delivery was uneventful. Developmental delay was evident since the first months of life. At 2 years, he developed generalized tonic-clonic seizures. Because of short stature, low growth velocity and delayed bone age, at 4 years he underwent growth hormone (GH) evaluation. Peak GH after two provocative tests revealed a partial GH deficiency. Clinical observation at 7 years disclosed a distinctive facial appearance, with microcephaly, prominent eyes, and beaked nose. Brain MRI showed left temporal mesial sclerosis. GTG banded karyotype was normal. Because of mental retardation, subtelomeric fluorescence in situ hybridization (FISH) analysis was performed, disclosing a relatively large deletion involving 4p16.2 --> pter (about 4.5 Mb), in the proband, not present in the parents. The smallest deletion detected in a WHS patient thus far includes two candidate genes, WHSC1 and WHSC2. Interestingly, that patient did not show shortness of stature, and that could be due to the haploinsufficiency of other genes localized in the flanking regions. Contribution of GH alterations and possible GH therapy should be further considered in WHS patients.

Abstract
AIM Isolated small bowel transplantation is becoming the treatment of choice for adult patients with serious parenteral nutrition (PN) related complications: we report our three-year experience (December 2000-December 2003) from a single Italian center (Modena-Italy), with one of the larger European series. METHODS We transplanted 14 patients, with a previous mean PN course of 27 months and a mean 21-month post-transplantation follow-up (range 3-36 months), obtaining a one-year actuarial survival rate of 92.3% with no intraoperative deaths. RESULTS We lost 1 patient (7.2%), died for post-transplantation overwhelming sepsis following Cytomegalovirus (CMV) enteritis. Thirteen patients are alive, with one-year actuarial graft survival rate of 85.1%: 1 patient underwent graft removal (7.2%) for intractable severe acute rejection. Our immunosuppressive regimen was based on tacrolimus and 3 induction protocols: daclizumab (8 patients) with steroids, alemtuzumab (4 patients) and thymoglobulin (2 patients) without steroids. In 9 cases, we added sirolimus. Nine recipients experienced 22 episodes of acute cellular rejection (ACR), treated successfully in all cases but one. One patient (7.2%) was treated successfully for Post Transplant Lymphoproliferative Disease (PTLD) and is disease-free after 8 months. CONCLUSIONS Small bowel transplantation can achieve optimal results depending on appropriate immunosuppressive management and candidate selection, added to shorter ischemia time and careful donor and graft selection.

Abstract
A case-control study was performed in order to determine whether expression of the progesterone receptor (PR) and/or aberrations of the PR gene contribute to the development of recurrent endometrial carcinoma. Primary tumours from 44 patients with recurrence of stage I endometrial carcinoma (patients) within 3 years after initial treatment were compared with tumours from 44 matched patients who were free of recurrence for a minimum of 3 years (controls). Paraffin wax-embedded primary tumours (n = 88) and recurrent tumours (n = 32) were analysed immunohistochemically for PR expression. A staining index (SI = 0-9) based on the staining intensity and the number of stained cells was calculated. DNA extracted from paraffin wax-embedded tissues was subjected to PCR-restriction fragment length polymorphism analysis (PCR-RFLP) for determination of the PROGINS DNA sequence alterations and the +331G/A-promoter polymorphism. Low PR expression (SI < 1.0) was observed in 7% of primary tumours derived from controls, 25% of primary tumours from patients with recurrence, and 38% of recurrent tumours. The expression of PR was significantly lower in primary tumours from patients with recurrence (SI = 4.0 +/- 0.5) than in the tumours in the control group (SI = 5.6 +/- 0.5) (T-test for paired analysis, p < 0.05). The PROGINS and +331G/A-promoter polymorphism were not related to age at diagnosis, tumour grade or myometrial invasion. The +331G/A-promoter polymorphism was present in 14% of primary tumours from patients without recurrence, compared with 17% of patients with recurrence. The PROGINS polymorphism was observed in 16% of primary tumours from patients without, and in 34% of patients with, recurrence (OR 2.6; 95% CI: 0.9-7.6). Most interestingly, patients who carried the PROGINS variant and in whom a PR-expressing tumour was diagnosed were at significantly enhanced risk of relapse (OR 4.7; 95% CI: 1.3-17.1). In conclusion, low PR expression tended to be associated with recurrent disease, and PR expression in tumours from patients carrying the PROGINS allele was predictive of the risk of recurrence.

Abstract
AIM In order to study the impact of clinical and diagnostic parameters on the clinical outcome of children with central nervous system tuberculosis (CNS-TB), we retrospectively reviewed all cases of CNS-TB diagnosed over a 32-year period at the Children's Hospital of Palermo, Italy. METHODS Data were collected with regard to the clinical, laboratory and demographic characteristics of patients, as well as the results of radiological investigations and data on clinical outcome. In relation to the date of introduction of new diagnostic methods (indirect as well direct) and to the change of treatment periods, the authors compared the clinical outcome of patients admitted prior and after 1984. They also classified the patients into 3 different stages of illness according to the severity of the disease on admission. RESULTS We identified 80 patients with CNS-TB. The mean age of the children was 3 years with 54% of patients younger than 5 years. The contact source was documented in 40 patients (50%). The mean duration of symptoms prior to admission was 22 days (range 5 days - 3 months). Mantoux skin test was positive on admission in 50 patients (62%). CSF smear microscopy and culture were positive in 29% and 45% of patients respectively. PCR for Mycobacterium tuberculosis introduced in 1994 was positive in 11 out of 13 tested patients. Determination of CSF gdT lymphocytes composition applied in 7 patients shows a predominance of Vg9/Vd2 T lymphocytes. Fifteen subjects (19%) died; 11 (13%) suffered from permanent sequelae. The died children and those with permanent sequelae were younger than the others (p<0.05). Prior to 1984, none of the patients were identified during early stage of illness and 4 out of 37 patients with stage II illness died. After 1985, 44% of children were in stage I and 2 out of 4 patients with stage III died (p<0.05). CONCLUSIONS Stage of disease and young age are still the decisive factors in the clinical outcome of children with CNS-TB. The availability of new advanced methods has improved the identification of patients with CNS-TB in stage I and therefore the possibility of an early treatment of such patients.

Abstract
Nonimmediate manifestations (i.e. occurring more than 1 h after drug administration), particularly maculopapular and urticarial eruptions, are common during beta-lactam treatment. The mechanisms involved in most nonimmediate reactions seem to be heterogeneous and are not yet completely understood. However, clinical and immunohistological studies, as well as analysis of drug-specific T-cell clones obtained from the circulating blood and the skin, suggest that a type-IV (cell-mediated) pathogenic mechanism may be involved in some nonimmediate reactions such as maculopapular or bullous rashes and acute generalized exanthematous pustulosis. In the diagnostic work-up, the patient's history is fundamental; patch testing is useful, together with delayed-reading intradermal testing. The latter appears to be somewhat more sensitive than patch testing, but also less specific. In case of negative allergologic tests, consideration should be given to provocation tests, and the careful administration of the suspect agents. With regard to in vitro tests, the lymphocyte transformation test may contribute to the identification of the responsible drug. Under the aegis of the European Academy of Allergology and Clinical Immunology (EAACI) interest group on drug hypersensitivity and the European Network for Drug Allergy (ENDA), in this review we describe the general guidelines for evaluating subjects with nonimmediate reactions to beta-lactams.

Abstract
Brain involvement in myotonic dystrophy type 1 (DM1) is characterised by cortical atrophy and white matter lesions. We compared the magnetic resonance imaging derived grey matter maps of 22 DM1 patients with those of matched, healthy controls using voxel based morphometry to evaluate the extension of global and regional cortical atrophy in DM1, as well as its relationships with clinical and genetic features. Patients had significantly reduced brain tissue volumes. Grey matter volume was inversely correlated with age; this inverse correlation was significantly stronger in DM1 than in controls. Neither the clinical and genetic characteristics nor white matter lesions were correlated with cortical atrophy. Grey matter atrophy was located mainly in the bilateral frontal and parietal lobes, in the bilateral middle temporal gyrus, and in the left superior temporal and occipital gyrus.

Abstract
SUMMARY Two Landrace Large White swine underwent angiography by the femoral route. In both cases, the superior left renal artery was embolized by injection of 2 ml of Glubran 2((R)), diluted with Lipiodol 1:1 thereby excluding the superior left kidney poles from blood flow. During the follow-up period, neither pig presented any clinical symptom correlated to the embolization procedure. Case 1 was sacrificed after 30 days and case 2 after 60 days. Macroscopic and microscopic analysis was performed in both animals. Long-term follow-up of the two cases after endovascular injection of Glubran 2((R)) showed that the embolization procedure was well-tolerated by the swine in terms of clinical symptoms and histological findings. Arterial occlusion was stable and a reasonable quantity of scar tissue appeared between 30 and 60 days, surrounding the ischaemic tissue. This follow-up experimental study offers further evidence that Glubran 2((R)) is a safe embolizing material for human use as far as its chemical activity is concerned.

Abstract
BACKGROUND Genetic polymorphisms of APO-E, homocysteine, and the IL-1 gene cluster (IL-1A, IL-1B, receptor antagonist IL-1RN) are associated with sporadic Alzheimer's disease and may involve interdependent pathways of neuronal toxicity. OBJECTIVE To determine whether these polymorphisms and the genetic determinants of homocysteine (methylenetetrahydrofolate reductase, MTHFR; methionine synthase, MTR; transcobalamin, TC) are associated with an increased risk of severe dementia in Alzheimer's disease. METHODS 152 patients with Alzheimer's disease and 136 controls were studied. The association of occurrence and dementia severity (Reisberg score <6 and >or=6) of Alzheimer's disease with APO-E, IL-1A, IL-1B, IL-1RN, MTHFR677 C-->T and 1298A-->C, MTR 2756 A-->G, and TC 776 C-->G polymorphisms was evaluated by multivariate logistic regression analysis after adjustment for age, sex, and age of onset of Alzheimer's disease. RESULTS IL-1A TT and IL-1B CT/TT associated genotypes were at risk of Alzheimer's disease (odds ratio 4.80 (95% confidence interval, 1.32 to 17.40), p = 0.017); the MTR 2756 AA genotype was at risk of severe dementia (OR 2.97 (1.23 to 7.21), p = 0.016); IL-1 RN*2 was protective (OR 0.28, (0.11 to 0.69), p = 0.006). Allele epsilon4 of the APO-E and IL-1B CC genotypes increased the risk of severe Alzheimer's disease associated with the MTR 2756 AA genotype by 3.3-fold and 1.5-fold, respectively. CONCLUSIONS Distinct determinants of the IL-1 gene cluster are related to the generation and progression of Alzheimer's disease. MTR only influences progression of the disease, which may be enhanced by carriage of allele epsilon4 of APO-E.

Abstract
AIM Tourette Syndrome (TS) shows a significant comorbidity with obsessive-compulsive disorders, behavioral problems (i.e. attention-deficit/hyperactivity disorders) and sleep disturbances. Several studies showed that sleep problems are common in TS patients affecting 12% to 62% of patients. Aim of this study was to evaluate the relationships between tics, sleep disorders and behavioral disturbances. METHODS Fourty-nine consecutive children and adolescents with tics have been studied by the following procedure: a) the Yale Global Tic Severity Scale (YGTSS) was administered in order to establish the severity of tics; b) the Child Behavior Checklist (CBCL) was used to evaluate behavioural disturbances; c) the Sleep Disturbance Scale for Children (SDSC) was filled out in order to assess the presence of sleep disorders. An age-matched control group was used for comparison. RESULTS All patients (either TS or non-TS) showed a higher prevalence of sleep disturbances versus the control group. Sleep-wake transition disorders (SWTD) were the most frequent sleep disturbances found in our sample, followed by disorders of initiating and maintaining sleep (DIMS). These latter sleep disturbances were highly correlated with the severity of tics. Internalization problems, anxiety/depression and attention and thinking problems were very frequent in our sample. Correlation analysis showed a positive relationship between internalization problems and DIMS and also between aggressive behaviour and respiratory disturbances during sleep (RDS). CONCLUSION The results obtained seem to confirm the literature reports on the strict relationship between tics and sleep disturbances, mainly SWTD, and further support the hypothesis of a dysfunction of arousal mechanism in TS.

Abstract
BACKGROUND & OBJECTIVES A possible relationship has been suggested between tic disorders and streptococcal infections. To understand the complex relationship between streptococcal infections and neuropsychiatric disorders in children the present study was done on colour Doppler echocardiography of patients with possible post-streptococcal tic disorders. METHODS The patients were 23 children (22 males, 1 female) affected by tic disorders, who at the time of the observation presented (or had presented in the past) signs of streptococcal infections temporally related to the onset or recrudescence of tic disorders. Echocardiographic examination and laboratory tests were performed on these children. RESULTS In 4 cases a mild mitral insufficiency and in 8 cases a minimal mitral insufficiency was seen, all haemodynamically not significant. Follow up studies (up to 1 yr) showed the consistency and persistence of these findings. Of the 12 patients with echocardiographic abnormalities, 10 displayed very high anti streptolysin O (ASO) titres, 5 showed positive cultures for GAS and 9 had abnormal ESR, even if no significant differences were found in respect to patients with tics and normal echocardiography. INTERPRETATION & CONCLUSION With the caution due to the design of study and to low number of patients, our data seem to indicate that the pathophysiology of GAS-infection related tic disorders is similar to that SC, at least in some cases.

Abstract
BACKGROUND & OBJECTIVES An association between the onset or recrudescence of some neuropsychiatric disorders in children such as tic disorders and group A streptococcal (GAS) infections has been suggested. No information is available on the characterization of GAS strains associated with such disorders. The present study was undertaken to characterize the GAS strains isolated from children with tic disorders and to determine and correlate the antistreptolysin O (ASO) titre with the presence of GAS. METHODS During 1996-2001, 368 children with tic disorders were investigated for possible exposition to streptococcal antigens. All children, at the time of the first visit and during the follow up visits were apparently healthy and showed no clinical evidence of streptococcal infections or post streptococcal sequelae. Blood and throat swab samples were collected and serological and bacteriological tests done. The isolates obtained were investigated for T pattern, M protein and emm type, as well as for the production of protease. RESULTS Of the 800 throat swabs studied 100, corresponding to 67 patients, were positive for GAS; 49 children were found positive for GAS only once during the study, 18 had more than one sample positive for different serotypes, 8 were positive twice or more for the same type. ASO titres of these children were, in general, elevated. Five types, namely type M12, 3, 13, 11, 1, accounted for 39 per cent of the isolates, M12 being the most common, but a large number of different types were also found. A large number of isolates (62%) showed an elevated prodution of protease in the casein plate assay. INTERPRETATION & CONCLUSION Despite the high level of ASO titres found, the results were not in favour of a particular virulence or invasivity of the isolates. Only a few colonies per sample were found indicating that factors different from the microbial virulence play a role in this type of disease.

Abstract
We have studied the presence and activity of components of the nuclear factor-kappaB (NF-kappaB) transcription factor in the hamster circadian system analyzing wheel-running activity, protein expression and DNA binding activity by electrophoresis mobility shift assays (EMSA). Non-rhythmic specific immunoreactive bands corresponding to a NF-kappaB subunit (p65) were found in hamster suprachiasmatic nuclei (SCN) homogenates. The active form of NF-kappaB evidenced by EMSA was clear and specific in SCN nuclear extracts. The administration of the NF-kappaB inhibitor pyrrolidine-dithiocharbamate (PDTC) blocked the light-induced phase advance at circadian time 18 (vehicle+light pulse: 2.08+/-0.46 h, PDTC+light: 0.36+/-0.35 h). These results demonstrate the presence and activity of Rel/NF-kappaB family proteins in the hamster SCN and suggest that these proteins may be related to the entrainment and regulation of circadian rhythms.

Abstract
From July 1995 to December 2001, 42 patients with leukemia aged 1-42 years underwent cord blood transplant (CBT) from unrelated, < or = 2 antigen HLA mismatched donors. In all, 26 patients were in < or = 2nd complete remission and 16 in more advanced phase. Conditioning regimens, graft-versus-host disease (GVHD) prophylaxis and supportive policy were uniform for all patients. The cumulative incidence of engraftment was 90% (95% CI: 0.78-0.91). The cumulative incidence of III-IV grade acute- and chronic-GVHD was 9% (95% CI: 0.04-0.24) and 35% (95% CI: 0.21-0.60), respectively. The 4-year cumulative incidence of transplant-related mortality (TRM) and relapse was 28% (95% CI: 0.17-0.47) and 25% (95% CI: 0.14-0.45), respectively. The 4-year overall survival (OS), leukemia-free survival (LFS) and event-free survival (EFS) were 45% (95% CI: 0.27-0.63), 47% (95% CI: 0.30-0.64) and 46% (95% CI: 0.30-0.62), respectively. In multivariate analysis, the most important factor affecting outcomes was the CFU-GM dose, associated with CMV serology (P=0.003 and 0.04, respectively) in influencing OS and with patient sex (P=0.008 and 0.03, respectively) in influencing LFS. Finally, CFU-GM dose was the only factor that affected EFS significantly (P=0.02). In conclusion, the infused cell dose expressed as in vitro progenitor cell growth is highly predictive of outcomes after an unrelated CBT and should be considered the main parameter in selecting cord blood units for transplant.

Abstract
Even when considering the possibility of organ rejection and the complications of immunosuppression, the risks associated with total parenteral nutrition therapy are life-threatening. Therefore, for patients with end-stage bowel disease small bowel transplantation (SBTx) is the only therapeutic option. The preferred method to procure these organs is debated, especially when, graft retrieval is associated with concurrent abdominal organ procurement of the pancreas, which shares part of the vascular inflow and outflow with the small bowel. While many surgeons procure the graft using the en bloc method, dissecting tissue at the back table, our preference is to use an in vivo technique, which results in shorter cold ischemia times and less bleeding during reperfusion of the pancreas/small bowel as well as decreased ascites production during the postoperative period and less edema and capsular bleeding of the pancreatic grafts. This article presents an analysis of 19 multiorgan cadaveric procurements using the in vivo technique with a focus on the quality of pancreas/small bowel postreperfusion properties during the first 5 to 6 postoperative months.

Abstract
AIM To evaluate the clinical characteristics, diagnostic methods and outcome of paediatric pulmonary tuberculosis (PTB) in relation to children's ages when observed. METHODS Children under 15, who had been admitted to the Children's Hospital with PTB were prospectively evaluated. Our sample included patients with a positive tuberculin skin test and signs or symptoms of tuberculosis (TB), including abnormal chest X-rays which suggested PTB. We collected demographic, clinical, radiographic and microbiological data from the patients, in addition to carrying out contact investigations in order to find a source case. All the patients involved in this study were subjected to anti-tuberculosis treatment. RESULTS Sixty-two patients (44% under 5) were eligible for inclusion in our study. Children with presenting symptoms were younger than asymptomatic patients (p<0.05). A source case was found in 38 patients out of 62 children (62%) and children under 5 were more likely to have a source case than that found with older children (p<0.05). Ghon complex (infiltrate + adenopathy) tended to occur in young children (median age of 3.25, p<0.05). Fourteen children (23%) had clinical specimens which tested positive for Mycobacterium tuberculosis (MT), and 20 (32%) for MT DNA according to a polymerase chain reaction (PCR). Resistant strains to 1 or more anti-tuberculosis drugs were found in 5 children and in 4 adult sources. The patients with minimal or no radiographic change during therapy displayed symptoms for a longer period of time and were infected by a resistant strain (p<0.05). CONCLUSION Improvements in case detection, case management and contact investigations are necessary for controlling paediatric TB, especially in young children. Given that any diagnosis of TB in children is supported by epidemiological and clinical evidence rather than isolating MT, detection of the source case is important in selecting appropriate treatment.

Abstract
Leukocytes, and in particular polymorphonuclear cells (PMN), play a role in the organ injury that characterizes the progression of vascular atherosclerotic disease (VAD) and diabetes mellitus (DM). We enrolled subjects with VAD, subjects with type 2 DM (DM2) and subjects with VAD and DM2. We evaluated the initial relative flow rate (IRFR) of PMN, using the St. George Filtrometer, the PMN membrane fluidity, labelling intact PMN cells with the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenylhexatriene (TMA-DPH), the PMN cytosolic Ca2+ content marking the cells with the fluorescent probe Fura 2-AM and the PMN integrin profile using the flow cytofluorimetry. All these evaluations were effected at baseline and after activation with 4-phorbol-12-myristate-13-acetate (PMA). At baseline and after activation the IRFR did not distinguish normal subjects from any group of patients. The PMN membrane fluidity at baseline differentiated only normal from DM2 subjects, while after activation no significant variation of this parameter was observed in normal, VAD, DM2 and VAD-DM2 subjects. The PMN cytosolic Ca2+ content, at baseline, discriminated only normal from VAD subjects with DM2, while after activation a significant increase of this parameter was evident in DM2 subjects and in VAD subjects with DM2. Regarding the PMN integrin pattern we observed, at baseline and after activation, a complex and non-univocal behaviour. In conclusion, the PMN rheological and metabolic pattern found in these groups of patients showed only small functional alterations while the integrin pattern was significantly different from that of normal subjects and added specific elements which may have potential therapeutical implications.
