RESUMEN

The Vaccination Calendar for Life is an alliance of scientific and professional societies of public health physicians, paediatricians and general practitioners in Italy which provides a periodical update on the ideal, scientifically driven vaccination calendar throughout lifetime. Since 2012, the Lifetime Immunization Schedule has represented a benchmark for Regional and National Authorities to set up the updated list of vaccines provided actively and free of charge to infants, children, adolescents, adults and the elderly by inclusion in the Triennial National Vaccination Plan (TNVP), and in the Essential Levels of Care (LEA). The impact of the different editions of the Lifetime Immunization Schedule on the TNVP was deep, representing the inspiring source for the present vaccination policy. The 2019 edition called for more attention to pregnant women immunization; risk groups vaccination; uniform high coverage with the MMRV vaccine; extension of Meningococcal B vaccination also at adolescent age; use of quadrivalent conjugate meningococcal vaccine also at 1 year of life; progressive decrease of the age of free-of-charge offer of influenza to ≥ 60 and then to ≥ 50 year-old population; implementation of flu immunization ages 6 months-6 years; HPV vaccination also offered to 25-year old women at the time of the first screening (gender neutral immunization already offered); sequential PCV13-PPV23 pneumococcal vaccination in 65 year-old subjects; increased coverage with rotavirus vaccine in infants and zoster vaccine in the elderly.

RESUMEN

INTRODUCTION: Multilevel cervical myelopathy without surgical treatment is generally poor in the neurological deficit without surgical decompression. The two main surgical strategies used for the treatment of multilevel cervical myelopathy are anterior decompression via anterior corpectomy or posterior decompression via laminctomy/laminoplasty. PRESENTATION OF CASE: We present the case of a 62 year-old lady, harboring rheumatoid artritis (RA) with gait disturbances, pain, and weakness in both arms. A C5 and C6 somatectomy, C4-C7 discectomy and, instrumentation and fusion with telescopic distractor "piston like", anterior plate and expandable screws were performed. Two days later the patient complained dysfagia, and a cervical X-ray showed hardware dislocation. So a C4 somatectomy, telescopic extension of the construct up to C3 with expandible screws was performed. After one week the patient complained again soft dysfagia. New cervical X-ray showed the pull out of the cranial screws (C3). So the third surgery "one stage combined" an anterior decompression with fusion along with posterior instrumentation, and fusion was performed. DISCUSSION: There is a considerable controversy over which surgical approach will receive the best clinical outcome for the minimum cost in the compressive cervical myelopathy. However, the most important factors in patient selection for a particular procedure are the clinical symptoms and the radiographic alignment of the spine. the goals of surgery for cervical multilevel stenosis include the restoration of height, alignment, and stability. CONCLUSION: We stress the importance of a careful patients selection, and invocated still the importance for 360° cervical fixation.

RESUMEN

The cause of the association between breast cancer (BC) and thyroid autoimmunity is still unknown. Na+/I- symporter (NIS) is highly expressed in BC cells, and previous studies demonstrated that iodine content in BC is lower than in remote normal breast tissue, suggesting a disorder of iodide uptake in BC. In this study, we evaluated the presence of putative serum autoantibodies able to block the function of NIS in BC patients with thyroid autoimmunity. IgGs were obtained from: a) 11 patients with BC and high antithyroglobulin (TgAb) and antithyroperoxidase (TPOAb) autoantibodies serum concentration; b) 34 patients with Hashimoto's thyroiditis (HT) (1 was euthyroid, 4 had subclinical hypothyroidism and 29 were overtly hypothyroid); c) 15 control subjects. The biological activity of NIS was studied using a chinese hamster ovary (CHO) cell line stably expressing NIS (NIS-CHO). The course of iodide accumulation in NIS-CHO was studied after addition of Na125 I in culture medium. The accumulation of iodide linearly increased between 2 and 10 min, reaching a plateau at 45 min. The preincubation of NIS-CHO with IgGs purified from sera of BC with the highest levels of TPOAb and TgAb caused an inhibition of iodine uptake of no more than 5%. Similar results were obtained using IgGs purified from patients with HT and control subjects. Our data showed no interference of autoantibodies on iodine uptake in patients with BC and thyroid autoimmunity and the very low percentage of inhibition of iodine uptake cannot explain the lower content of iodine in BC tissue.

RESUMEN

The apoptotic response and the level of expression of p53 and of three genes transcriptionally activated by p53 (Mdm2, p21 and bax) were investigated in UV-sensitive cells from patients with xeroderma pigmentosum (XP) or Cockayne syndrome (CS). These disorders are due to different genetic defects affecting transcription-coupled repair (TCR) and/or global genome repair (GGR), the nucleotide excision repair subpathways which remove UV-induced lesions from the transcribed strand of active genes or from the rest of the genome, respectively. After 20 J/m2 UV light, normal and GGR-defective XP-C fibroblasts showed rapid increase in p53, late induction of Mdm2 and no evidence of apoptosis even 96 h after irradiation. In contrast, in XP-A (defective in GGR and TCR), CS-A and CS-B (defective only in TCR) fibroblasts, the p53 increase was not followed by Mdm2 induction and the persistence of high levels of p53, due to the lack of its degradation by Mdm2, was associated with the appearance of apoptosis. Besides indicating that the persistence of DNA damage in the transcribed strand of active genes leads to apoptosis, these findings provide the first evidence that the lack of activation of Mdm2 plays a key role in the cascade of events leading to apoptosis.

RESUMEN

Wegener's granulomatosis (WG) is a granulomatous necrotizing vasculitis associated with the presence of ANCA, predominantly directed against proteinase 3 (PR3). The titres of ANCA correlate with disease activity and titre increases may precede disease exacerbations. Previously, we have shown that it is possible to induce autoimmune disease (systemic lupus erythematosus (SLE) and anti-phospholipid syndrome) in naive mice following active immunization with human autoantibodies, namely anti-DNA and anti-cardiolipin, respectively. The mice developed first anti-autoantibodies and, after about 4 months anti-anti-autoantibodies (Ab3), simulating auto-antibodies (Ab1) in their binding activities, and their presence was associated with the development of disease manifestations, characteristic of the human disease. So far, there is no good animal model for WG. In the current study we have immunized mice with human ANCA with the aim of inducing experimental WG. In two separate studies 30 mice were immunized in their footpads with autoantigen-purified IgG fraction (ANCA) from the sera of two patients with untreated WG, emulsified in Freund's complete adjuvant, followed 3 weeks later by ANCA injection in PBS. In the first experiment mice immunized with ANCA developed sterile microabscesses in the lungs after 8 months, and died after 8-15 months. In the second experiment, mice immunized with ANCA developed after 4 months mouse ANCA, with specificity both to PR3 and to myeloperoxidase, as well as anti-endothelial autoantibodies (AECA), as shown by radioimmunoprecipitation. Pathologically, the immunized mice developed proteinuria but not haematuria, and histological sections of the lungs demonstrated mononuclear perivascular infiltration, while diffuse granular deposition of immunoglobulins was noted in the kidneys. Our results point to a pathogenic role of ANCA in WG, and confirm the importance of the idiotypic network in the etiopathogenesis of autoimmune conditions.

RESUMEN

We selected two clones, isolated from the human colocarcinoma cell line LoVo, showing a sensitivity to doxorubicin similar to (LoVo clone 5) or three times lower than (LoVo clone 7) the parental cell line. Since vimentin was atypically expressed in a human breast carcinoma cell line made resistant to doxorubicin, we looked at vimentin expression in these two clones with spontaneously different sensitivity to the drug. For comparison we used the parental cell line LoVo WT and LoVo/DX made resistant pharmacologically. mRNA for vimentin was undetectable by Northern blot analysis in LoVo WT and in LoVo clone 5, while expression of this gene was high in LoVo clone 7 and in LoVo/DX. This increase in mRNA levels was not related to an amplification of DNA, as suggested by Southern blot analysis. Immunofluorescence and immunocytochemistry findings confirmed, at protein level, the mRNA data. In LoVo clones 5 and 7, there were respectively 8.6% and 71% vimentin-positive cells, although the two clones showed similar expression of multidrug resistance gene 1 (mdr-1) and accumulated intracellular doxorubicin at similar levels. Similarly, drug efflux was the same for both clones. Our results show for the first time that cells resistant to doxorubicin express vimentin independently of the mdr glycoprotein. However when cells from clone 5 were transfected with human vimentin cDNA, they did not become resistant, indicating that vimentin can be considered as a marker of resistance in these cells but does not give rise to a resistant phenotype by itself.

RESUMEN

The antigenic structures recognized by anti-endothelial cell antibodies (AECA) in sera from 10 Wegener's granulomatosis (WG) and 12 systemic lupus erythematosus (SLE) patients with signs of vasculitis were characterized by immunoprecipitation of selectively radiolabeled surface membrane proteins from human umbilical vein endothelial cells. Electrophoretic analysis of the immunoprecipitated proteins revealed reactivities against endothelial antigens ranging in size from 200 to 25 kDa. AECA antigens were not cell specific, since the same sera also reacted, at least in part, with radiolabeled human fibroblast surface proteins. The majority of WG patients displayed a constant precipitation pattern of five proteins (180, 155, 125, 68, and 25 kDa). On the contrary, AECA from SLE sera reacted with a more heterogeneous series of endothelial proteins. A group of four proteins, however, was also found in the majority of SLE sera: 200, 180, 155, and 25 kDa. In addition, some endothelial antigens were immunoprecipitated only by WG (125 kDa) or by SLE sera (200 kDa), suggesting a different endothelial reactivity in different vasculitic processes. The reaction did not involve intracellular proteins as demonstrated by the lack of reactivity of SLE sera negative for AECA but positive for anti-cytoplasmic or anti-nuclear antibodies. These data confirming that AECA recognize surface endothelial determinants further support a potential pathogenetic role for these antibodies in autoimmune vasculitis.

RESUMEN

Vascular endothelium forms a dynamic interface between blood and underlying tissues. Endothelial monolayer integrity is required for controlled vascular permeability and to preclude exposure of subendothelial cell matrix to circulating cells. Recent studies have established that cultured human umbilical vein endothelial cells (ECs) express receptors for plasminogen (plg) and urokinase-like plasminogen activator (uPA). In the present study, we provide evidence that in EC, uPA receptor is present in focal contacts and at cell-cell contact sites. In these cells, addition of plg and uPA to confluent EC generates a retraction of the monolayer that is evidenced by loss of cell-cell contacts and increase in monolayer permeability. The phenomenon is reversible even after 6 hours of plg-uPA treatment. Inhibition of plg-uPA effect is obtained with plasmin inhibitors, as well as reagents that block binding of uPA or plg to the cell surface. The retractive effect of plg-uPA is concomitant to surface activation of plasminogen and to the loss of cell-cell activation of plg can induce EC retraction, possibly by causing proteolysis at specific cell-cell contacts and cell-matrix sites. This process may be important in mediating the passage of metastatic tumor cells through an intact EC monolayer as well as in regulating contacts between circulating cells and endothelium.

RESUMEN

In this study we characterized alpha v beta 5 integrin on HT-1080 fibrosarcoma cells. First, alpha v beta 5 integrin was immunoprecipitated by 125I-surface labeled HT-1080 cells using a polyclonal antibody specific for beta 5 subunit (cytoplasmic domain). A heterodimer consisting of a beta 5-chain running at 100 kD (reduced) and 90 kD (non-reduced) associated with an alpha-chain 145 kD (non-reduced) and 125 kD (reduced) was obtained by SDS-PAGE and autoradiography. By double-immunofluorescence labeling, we then investigated alpha v beta 5 distribution on HT-1080 cells. Upon staining with anti-beta 5 subunit antibody, alpha v beta 5 was detected in focal contacts on cells attached to vitronectin (vn), co-localizing with vinculin at the end of actin filaments. Comparative analysis of alpha v beta 5 and alpha v beta 3 showed that both receptors can occupy the same focal contact, although on the same cell mostly they are clustered in independent focal contacts. Focal distribution of alpha v beta 5 was also found on normal human fibroblasts attached to vn, suggesting that this is not a specific feature of HT-1080 cells. Finally, we investigated the role of alpha v beta 5 and alpha v beta 3 integrins in mediating HT-1080 cell adhesion to vn. Inhibition studies using antibodies with function-blocking activity to alpha v beta 5 and alpha v beta 3 suggest a primary role of alpha v beta 5 to support cell adhesion, with a weak contribute of alpha v beta 3. Their activity can be modulated by divalent cations. Our results provide the first evidence of focal distribution of alpha v beta 5 integrin on cells attached to vn.

RESUMEN

The value of rectal endosonography was investigated in the follow-up of the patients submitted to anterior resection for rectal cancer. Rectal endosonography was performed on 42 patients who had been operated on two months to five years before; all patients were monitored according to a carefully planned follow-up schedule including clinical and instrumental examinations and laboratory tests. Sixteen patients had altered clinical and laboratory data; 26 were completely asymptomatic. In the latter group, no signs of local recurrences were found, while in 4 cases the rectal wall appeared homogeneously thickened and hypoechoic: this pattern was due to postoperative or post-irradiation hyperemic-edematous phenomena. In 14 of 16 symptomatic patients, a mass was detected--in 9 of them inhomogeneous and hypoechoic and developing mainly in the perirectal perianastomotic tissue and in 5 limited to the rectal wall, in the anastomotic area. In the last 2 cases, no lesions were found. Both the manual and the stapler anastomoses were always demonstrated, which exhibited different US patterns. US findings were compared with histologic results or were clinically checked in the subsequent follow-up. To conclude, rectal endosonography proved to be useful in the postoperative follow-up of this kind of patients even though it did not allow the differential diagnosis between fibrosis and local recurrence.

RESUMEN

The production and characterization of two new monoclonal antibodies (MAbs), designated MAR4 and MAR5, raised against the partially purified alpha 5 beta 1 integrin, are described. The reactivity of these 2 MAbs on tumor cell lines indicated that they reacted on all the cells expressing the beta 1 subunit independently of the alpha 5 expression. Both MAbs were found to immunoprecipitate on 3 cell lines, a protein of 120 KD corresponding to the molecular weight be the beta 1 chain, in addition to proteins of other MW corresponding to the alpha subunits differentially expressed by these cells. The cross-competition experiments showed that MAR4 and MAR5 recognize the same epitope. These 2 MAbs seem to be useful reagents for the characterization of the VLA expression in tumor cells.

RESUMEN

The fibrinolytic activity of cancer cells has been repeatedly implicated in mechanisms of local spread and tumour invasiveness. Mononuclear phagocytes associated with solid tumours might also contribute to fibrin dissolution at the tumour/host interface through the expression of plasminogen activator (PA) activity. We have investigated the PA activity of tumour-associated macrophages (TAM) from 4 transplanted murine tumours in syngeneic hosts; peritoneal macrophages (native and thioglycolate-elicited) from both tumour-bearing and control animals were studied as reference cells. TAM from 3 tumours (MSV, mFS6, MN/MCAI) had basal levels of PA activity (20% plasminogen-independent) comparable to or higher than those of thioglycolate-elicited peritoneal macrophages from the same tumour-bearing animals. TAM isolated from 1 tumour (MS2) had a PA which was very low (60% plasminogen-independent), but higher than the activity of unstimulated peritoneal macrophages. Molecular analysis of PA by SDS-PAGE electrophoresis and fibrin autography revealed in all macrophages a single species having an apparent MW of 48 kDA. It thus appears that, in some experimental neoplasms, tumour cell vicinity may represent an in vivo stimulus for macrophage PA expression.

RESUMEN

The relationship between 31 variables and survival after acute myocardial infarction was evaluated in 432 patients discharged from our Coronary Care Unit from 1975 to 1984. The patients were followed for 1 to 105 months and either univariate and multivariate analysis were performed. For end-point death the significant variables (p less than 0.05) selected by the univariate analysis were: age, diabetes, smoke, heart rate at recovery, supraventricular arrhythmias, cardiac failure and complex ventricular arrhythmias either during recovery, either after discharge and finally spontaneous angina after hospital discharge. Meanwhile, for the end-point cardiac death age, smoke and supraventricular arrhythmias were not yet significant while arterial pressure at recovery and effort angina after hospital discharge were. Multivariate analysis identified cardiac failure during recovery, diabetes, complex ventricular arrhythmias before and spontaneous angina after discharge as independent variables contributing to total mortality: effort angina was a further significant one relatively to cardiac death. Thus, our study points out the importance of multivariate survival analysis when evaluating the relationship between survival after discharge for the effect of other prognostic factors. Moreover, providing identification of high risk cohorts permits appropriate interventions designed to lessen risk.

RESUMEN

We have investigated here the coordinate expression of both procoagulant (PCA) and fibrinolytic (FA) activity of cells from 16 human ovarian carcinoma cases. To avoid interference of contaminating host cells, we used cells isolated in primary culture from ascitic fluid or from solid tumor. The FA was determined in cellular extracts by an amidolytic assay in the presence of fibrin monomers. FA, which was plasminogen dependent in almost all of the cases, showed a wide range of activity (from less than 0.001 to 2.30 UK units/mg protein). The molecular analysis of plasminogen activator (by SDS-PAGE and fibrin autography) showed a single molecular form of 52,000 daltons, inhibited by an antibody against human urokinase. PCA, studied with a one stage clotting assay in disrupted cells, was of tissue thromboplastin type in all instance and varied from 12.0 to 1300 thromboplastin units/10(4) cells. No simple correlation was found between FA and PCA in the cellular samples studied; moreover, for neither parameter was it possible to find any changes with the staging of the disease.
