Abstract
During an oomycete survey in December 2015, 10 previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described Halophytophthora species, the 10 new Halophytophthora taxa and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny of the genus Halophytophthora s.str. showing for the first time a structure of 10 clades designated as Clades 1-10. Nine of the 10 new Halophytophthora taxa resided in Clade 6 together with H. polymorphica and H. vesicula. Based on differences in morphology and temperature-growth relations and a multigene (LSU, ITS, Btub, hsp90, rpl10, tigA, cox1, nadh1, rps10) phylo-geny, eight new Halophytophthora taxa from Portugal are described here as H. brevisporangia, H. cele-ris, H. frigida, H. lateralis, H. lusitanica, H. macrosporangia, H. sinuata and H. thermoambigua. Three species, H. frigida, H. macrosporangia and H. sinuata, have a homothallic breeding system while the remaining five species are sterile. Pathogenicity and litter decomposition tests are underway to clarify their pathological and ecological role in the marine and brackish-water ecosystems. More oomycete surveys in yet undersurveyed regions of the world and population genetic or phylogenomic analyses of global populations are needed to clarify the origin of the new Halophytophthora species.

Abstract
SCODIAC was a pilot study which revealed an increasing use of SGLT2i in 123 outpatients affected with Heart Failure (HF) and Type 2 Diabetes Mellitus. SCODIAC-II study, the second phase of the program, has been carried out to determine diagnostic and therapeutic pathways in a larger group of patients and to verify whether the use of innovative antidiabetic therapies could modify echocardiographic parameters and cardiovascular therapies. 406 HF-diabetic patients, referred to Cardiologists and Diabetologists of pertaining healthcare districts in Campania, were enrolled in this retrospective study and divided in Group A, composed of 136 patients with preserved Ejection Fraction (HF-pEF)(> 45%) and Group B, formed of 270 patients with reduced EF (HF-rEF)(≤ 45%). All patients had performed periodic clinical and echocardiographic evaluations. The antidiabetic therapies resulted modified after 1 year with a greater use of GLP1-AR, gliptins and SGLT2i. Cardiovascular therapies resulted also modified with a greater use of sacubitril/valsartan and a reduction of ACEi and ARBs in HF-rEF patients. Echocardiography E velocity, A velocity and E/e' ratio resulted markedly reduced in 25 HF-pEF and in 60 HF-rEF patients treated with SGLT2i, in respect to both the whole sample of subjects at beginning and the other diabetic patients. LAVi resulted reduced only in HF-pEF patients and EF increased only in HF-rEF patients. The approach to the patients with HF and diabetes must necessarily take place in the healthcare districts, be multidisciplinary and integrated. SGLT2i could improve left ventricular function in HF-rEF patients and modify cardiovascular therapies, almost in this setting of patients.Trial registration The protocol was approved by the University of Naples Federico II Ethics Committee and registered at ClinicalTrial.gov (CT04375943). The principles outlined in the Declaration of Helsinki were followed.

Abstract
The killer cell immunoglobulin-like receptor (KIR)-human leukocyte antigen (HLA) interaction represents an example of genetic epistasis, where the concomitant presence of specific genes or alleles encoding receptor-ligand units is necessary for the activity of natural killer (NK) cells. Although KIR and HLA genes segregate independently, they co-evolved under environmental pressures to maintain particular KIR-HLA functional blocks for species survival. We investigated, in 270 Italian healthy individuals, the distribution of KIR and HLA polymorphisms in three climatic areas (from cold north to warm south), to verify their possible geographical stratification. We analyzed the presence of 13 KIR genes and genotyped KIR ligands belonging to HLA class I: HLA-C, HLA-B and HLA-A. We did not observe any genetic stratification for KIR genes and HLA-C ligands in Italy. By contrast, in a north-to-south direction, we found a decreasing trend for the HLA-A3 and HLA-A11 ligands (P = 0.012) and an increasing trend for the HLA-B ligands carrying the Bw4 epitope (P = 0.0003) and the Bw4 Ile80 epitope (P = 0.0005). The HLA-A and HLA-B KIR ligands were in negative linkage disequilibrium (correlation coefficient -0.1211), possibly as a consequence of their similar function in inhibiting NK cells. The distribution of the KIR-HLA functional blocks was different along Italy, as we observed a north-to-south ascending trend for KIR3DL1, when coupled with HLA-B Bw4 ligands (P = 0.0067) and with HLA-B Bw4 Ile80 (P = 0.0027), and a descending trend for KIR3DL2 when coupled with HLA-A3 and HLA-A11 ligands (P = 0.0044). Overall, people from South Italy preferentially use the KIR3DL1-HLA-B Bw4 functional unit, while those from the North Italy equally use both the KIR3DL2-HLA-A3/A11 and the KIR3DL1-HLA-B Bw4 functional units to fight infections. Thus, only KIR3DL receptors, which exert the unique role of microbial sensors through the specific D0 domain, and their cognate HLA-A and HLA-B ligands are selectively pressured in Italy according to geographical north-to-south distribution.

Abstract
AIM To identify a possible role of home echocardiography for monitoring chronic heart failure (CHF) patients. METHODS We prospectively investigated 118 patients hospitalized during the last year for CHF who could not easily reach the pertaining District Healthcare Center. The patients were followed up with 2 home management programs: one including clinical and electrocardiographic evaluations and also periodic home echocardiographic examinations (group A), the other including clinical and electrocardiographic evaluations only (group B). RESULTS At the end of the 18-mo follow-up no signi-ficant differences were observed between the 2 groups as regards the primary endpoint: rehospitalization occurred in 4 patients of the group A and in 6 patients of the group B; major cardiovascular events occurred in 2 and in 3 patients, respectively. No significant differences were observed with respect to the secondary endpoints: one vascular event appeared in both the groups, 3 cardiovascular deaths occurred in group A and 2 in group B. No significant differences were observed between the 2 groups as regards the composite endpoint of death plus hospitalization. CONCLUSION Home echocardiography for monitoring of CHF patients does not improve the cardiovascular endpoints. In our CHF patients, a low incidence of vascular events was observed.

Abstract
A new variant of HLA-DQB1*04:03 allele officially designated as HLA-DQB1*04:03:02 was detected in two unrelated Caucasoid individuals by polymerase chain reaction-sequence-specific primers and SBT. The new allele nucleotide sequence differs from HLA-DQB1*04:03:01 for a single silent point mutation in exon 2 at position 159, codon 21.

Abstract
Uncertainty still exists on the role of polymorphisms outside the HLA-DRB1 binding site or inside the HLA-DRB3 binding groove in unrelated hematopoietic SCT (HSCT). The ideal model to solve the conundrum consists of the transplants mismatched for HLA-DRB1*14:01/*14:54 and/or for HLA-DRB3*02:01/*02:02. A task force was set up in Italy to recruit transplanted pairs defined as HLA-DRB1*14:01 before 2006, the year crucial for the proper definition of the HLA-DRB1*14:54 allele in molecular biology. Out of 2723 unrelated pairs, 189 transplanted in Italy from 1995 to 2006 were HLA-DRB1*14:01 positive; 103/189 pairs with good historical DNA were retyped for HLA-DRB1*14 and HLA-DRB3 at-high resolution level; 31/103 pairs had HLA-DRB1*14 and/or HLA-DRB3 mismatched; 99/103, having complete clinical data, underwent statistical analysis for OS, TRM, disease-free survival and acute and chronic GvHD. No significant involvement of HLA-DRB1*14:01/*14:54 or HLA-DRB3*02:01/*02:02 mismatches was found, either alone or combined. Our findings suggest that disparities at exon 3 of the HLA-DRB1 gene seem unlikely to influence the outcome after HSCT. The same may be envisaged for HLA-DRB3(*)02:01 and (*)02:02 alleles which, although differing in the Ag binding site, seem unable to modulate an appreciable immune response in an HSCT setting.

Abstract
BACKGROUND Expected benefits of gluten-free diet (GFD) in coeliac patients include healing of small intestinal mucosa, but it remains unclear to what extent this benefit is achieved in adults. AIM To assess factors affecting histological outcome of GFD in a large cohort of adult coeliac patients. METHODS We extracted information on 465 consecutive coeliac patients studied before and during GFD. RESULTS Duodenal biopsies at diagnosis were classified as Marsh I in 11, II in 25 and III in 429 cases. After a median 16 months GFD, 38 (8%) patients had histological 'normalization', 300 (65%) had 'remission' with persistent intraepithelial lymphocytosis, 121(26%) had 'no change' and 6 (1%) had 'deterioration'. Coeliac disease related serology was negative in 83% of patients with Marsh III lesion during GFD. Male gender and adherence to GFD were independently associated with histological 'normalization' and 'remission'. Persistence of intraepithelial lymphocytosis was not associated with human lymphocyte antigen gene dose or with Helicobacter pylori infection. CONCLUSIONS Complete normalization of duodenal lesions is exceptionally rare in adult coeliac patients despite adherence to GFD, symptoms disappearance and negative CD related serology. Control biopsies are mandatory to identify lack of response to gluten-free diet.

Abstract
UNLABELLED The objective of this systematic review of the literature is to evaluate whether a laparoscopic operation can be performed on patients with occlusive or abdominal aortic aneurysm as a minimally invasive and durable alternative. For this purpose, the literature was reviewed and laparoscopic surgery results were compared with those of conventional and endovascular surgery. All series were included, even when containing also one case. Operative and clamping times, mortality and morbidity and hospital stay were evaluated. Thirty-five studies were identified about conventional (4), minilaparotomy (4), endovascular (4), total (12) and video-assisted (11) laparoscopic surgery. Operative and clamping times were shorter for video-assisted procedures than total-laparoscopic procedures. The mortality rate ranged from 3% to 4.5% for conventional surgery, from 0% to 3% for endovascular surgery, from 0% to 6% for total-laparoscopic surgery and from 0% to 4.2% for video-assisted laparoscopic surgery. A variable morbidity was described for all techniques, with a higher incidence in total-laparoscopic surgery. Mean hospital stay was similar for laparoscopic surgery procedures. The learning curve of a surgical team performing laparoscopic surgery improves the RESULTS Laparoscopic abdominal aortic surgery is feasible and may offer good postoperative recovery with excellent mid-term patency. Shorter hospital stay and simple mid-term follow-up allow more comfort for the patient and probably monetary savings for the community. A steep learning curve is needed. For these reasons laparoscopic video-assisted technique can be considered a third means of treating severe occlusive and aortic aneurysm, but only new instruments for performing aortoprosthetic anastomoses can diffuse the total laparoscopic technique as a routine approach.

Abstract
AIM Trauma of the thoracic aorta for blunt trauma shows a very high incidence of mortality. Hospital mortality rate after aortic open surgery is between 15% and 30%. Endovascular management represents an alternative treatment Associated lesions are usually seen in those critical patients. Hemothorax may be present. The authors propose a combined treatment of endovascular repair for the aortic lesion and video-assisted thoracoscopy surgery (VATS) for the treatment of chest bleeding complications. METHODS The authors report a series of three patients with post-traumatic aortic lesion and hemothorax. In two patients endovascular procedure was first performed, followed by VATS, few days later, for retained hemothorax. In the third patient the two procedures were performed at the same time because of the patient's critical conditions. RESULTS There was technical success of stent-graft placement in all the treated cases. No postoperative mortality. No postoperative paraplegia. No VATS converted to thoracotomy. The postoperative follow-up time range between 10 and 19 months. CONCLUSION Considering the relatively short procedural time and minimally invasive approach of both techniques, the concomitant use of them may represent an alternative to standard open surgery in cases of thoracic aorta lesions associated with hemothorax. Those procedures may be performed sequentially or together in emergency cases with intra-thoracic more active bleeding to exclude or to treat intra thoracic bleeding.

Abstract
By using polyethylene glycol precipitation at low concentration (PEG test) and the radiolabeled C1q binding test, immune complexes were detected sera from acute (23/28) and chronic (28/32) hepatitis patients, hemodialyzed patients with chronic hepatitis B surface (HBs) antigenemia (7/19), and asymptomatic HBs antigen carriers (2/11). After treatment of PEG precipitates with acidic pH, heating, or proteolytic enzyme (protease), electroimmunodiffusion or radioimmunoassay revealed the presence of HBs antigen or antibody in dissociated immune complexes in sera from several acute and chronic hepatitis patients. Electron microscopy showed immune complexes of HB virus in 9 of 12 PEG precipitates obtained from PEG-test-positive sera; these 9 precipitates were from patients with acute or chronic hepatitis and the other three from chronic HBs Ag carriers. Free HB virus particles were observed after protease digestion of PEG precipitates. Neither immune complexes nor virus particles were seen in precipitates from PEG-test-negative but HBs-Ag-positive sera from chronic carriers.

Abstract
OBJECTIVE To compare the effectiveness of a high-specification foam mattress (control) with a high-tech (Duo2, Hill Rom) alternating/continuous low-pressure mattress (treatment) in the prevention of pressure ulceration. The study also evaluated if there is a difference in performance between the two working modalities (alternating and continuous low pressure) of the high-tech mattress in a comparable sample of patients. METHOD Thirty-three patients were observed for two weeks in the control group. In the treatment group, 86 patients were randomised to receive alternating low pressure and 84 continuous low pressure. Incidence of pressure ulcers in both arms was recorded. Student's t-test was used to compare all Braden scores, and the chi-square test and Fisher's exact test to evaluate differences between groups. RESULTS There was a high difference in the number of new pressure ulcers in the control group when compared with the treatment group. There was no difference in performance between the alternating and continuous low-pressure modes. However, the sample size is too small to prove or disprove a statistically significant difference between the two modalities. CONCLUSION The high-tech mattress was markedly more effective than the high-specification foam mattress in preventing the onset of pressure ulcers. Initial data suggest that the use of alternating or continuous low pressure made little or no difference to the results.

Abstract
Apoptosis represents a mode of cellular death genetically programmed to maintain homeostasis of tissues. In specific pathologic circumstances, the death program may be activated by various environmental factors such as exposure to toxic substances or bacteria or deprivation of nutrients. From this point of view, apoptosis is considered the final event in several pathologies. In ophthalmology, experimental evidence has confirmed that apoptosis is a type of cellular death involved in various pathologic processes including glaucoma, retinitis pigmentosa, ischemic retinopathy, corneal reparative processes, cataract, and retinoblastoma. The aim of this article is to review the most recent results published in this field and to describe some of the molecular mechanisms responsible for the activation of the apoptotic program in some important ocular disorders. The understanding of such mechanisms could outline new therapeutic strategies for the prevention of cellular death in ophthalmology.

Abstract
Modifications in tumour antigen-derived epitopes that stabilize the major histocompatibility complex (MHC)-peptide complex result in enhanced stimulatory capacity and improved immunogenicity of the altered peptide. These epitope analogues are attractive candidates for the development of peptide-based vaccine trials. Any modification, however, in tumour antigens may induce T-cell responses that could either fail to react against the naturally occurring peptides or represent only a subset of the total antigen-specific repertoire. In the present study, we performed a critical analysis of the ability of cytotoxic T-lymphocyte (CTL) clones, derived from two melanoma patients through stimulation with the A27L peptide analogue, to cross-react with the naturally processed Melan-A/MART-1 (Melan-A) peptides in terms of T-cell receptor (TCR) affinity, functional avidity and fine antigen specificity. We found that all the A27L-specific clones analysed possessed a very low avidity for the natural Melan-A peptides, and that their binding affinity for human leukocyte antigen (HLA) tetramers complexed with both the modified and the natural Melan-A peptides did not strictly correlate with their functional avidity. We also observed that these clones were able to cross-recognize both natural Melan-A peptides in one patient, but only one peptide in the second patient. We discuss the capability of the A27L peptide analogue to stimulate all the available Melan-A-specific repertoire.

Abstract
In this paper the Authors consider the concept of stunning/hibernating myocardium, analizing the most recent articles and reviews in literature, until April 2002 (database PubMed). Dysfunctional segments with normal perfusion and normal glucose utilization are considered to be "stunned", and dysfunctional segments with reduced perfusion and preserved glucose utilization are considered to be "hibernated". Together with the two major hypothesis (generation of oxygen-derived free radicals and transient calcium overload) in developing of dysfunctional myocardium after ischaemia, recent studies have demonstrated an important role in down-regulation of beta-adrenergic receptors both in the stunned and in the hibernated segments. Moreover, the increase of negatively inotropic cytokines TNF-alpha and NOS2 has been observed in dysfunctional segments. The number of copies of mRNA has been quantified by reverse transcription-polymerase chain reaction (reverse-PCR).

Abstract
Psittacosis marked by liver and spleen involvement and minimal pericarditis was observed in an 18-year-old patient hospitalized for fever of 1 month duration. Liver tests revealed cholestasis. Ultrasonography revealed multiple nodular formations in the liver and spleen, images confirmed on computed tomography. Liver biopsy showed granulomatous with hyperplasia of the Kupffer cells surrounded by healthy tissue. The diagnosis was confirmed by complement fixation. Treatment with tetracycline led to rapid remission of the fever and normalization of the liver tests and hepatic images.

Abstract
While tumor-associated antigen (TAA)-specific CD8(+) T lymphocytes have been detected in metastatic melanoma patients, immune response in early disease phases has not yet been carefully evaluated. We looked for circulating cytotoxic T lymphocytes (CTL) directed against Melan-A / MART1, tyrosinase, gp100 and MAGE-3 antigens in patients with a diagnosis of primary cutaneous melanoma by using fluorescent HLA-A2 tetramers. In five out of six cases high numbers of CD8(+)/tetramer(+) cells could be detected by flow cytometry, and in four patients lymphocyte populations specific for two different melanoma antigens (Melan-A/MART1 and tyrosinase) were contemporaneously present. The TAA-specific cells could represent as much as 1/220 T lymphocytes in the circulating CD8(+) population. When tetramers were used to monitor the in vitro expansion of TAA-specific CTL precursors upon antigen-specific stimulation, a diverse expansion potential was evidenced in CTL from the different donors and, more strikingly, in CTL specific for the different TAA. Melan-A/MART1-specific CTL clones derived from two patients exhibited a broad range of avidity. Only the highest avidity clones, representing about 50 % of the cases analyzed, were tumor specific. By correlating tetramer staining with clone avidity, we found that tetramer fluorescence intensity could represent a good indicator of TCR affinity, but not of overall clone avidity.

Abstract
To seek some specific biochemical markers of age-related macular degeneration (AMD), coenzyme Q10 (CoQ10) levels were determined in plasma and platelets from 19 exudative AMD patients and 19 age-matched controls. Lipid peroxidation was followed in plasma in vitro after the addition of a free radical initiator. Most patients had lower plasma CoQ10 content than most controls. Plasma from controls showed greater capacity to oppose the oxidative damage. These results support the concept that free radicals play a pathogenic role in AMD and that CoQ10 may have a protective effect.

This action would be lied to increased synthesis of GMPc. The antiaggregant property pf nitrates may be leave open the problem to include the nitrates between the drugs able to influence the prognosis of myocardial infarction both in acute and chronic phase, such as betablockers, ASA and thrombolytics.

Abstract
PURPOSE To assess in vitro the potential of the free radical scavenger ubiquinone Q10 in preventing keratocyte apoptosis after argon fluoride (ArF) excimer laser irradiation. METHODS Cultured rabbit keratocytes were irradiated at very low single-pulse laser fluences. The cumulative effects generated by three total fluence doses between 12 and 45 mJ/cm2, representative of single-pulse subablative doses during photorefractive keratectomy (PRK) in humans, were evaluated. We employed the following parameters to compare pretreated (10 microM ubiquinone Q10) and untreated samples: 1) number and morphology of living cells by Trypan blue test and ultramicroscopy, respectively; 2) level of free-radical formation assessed by malonaldehyde quantitation; 3) cellular energy level evaluated by ATP assay. RESULTS Excimer laser irradiation kills cultured keratocytes by inducing apoptosis. The effect increases with the cumulative fluence dose. In the samples pretreated with ubiquinone Q10 there were significantly fewer cumulative apoptotic events than in the untreated ones. Quantitative analysis of malonaldehyde cellular levels suggested this protective action of ubiquinone Q10 was connected with its ability to scavenge laser-generated free radicals. ATP assay also confirmed that it raised cellular energy levels. CONCLUSIONS The treatment of corneal keratocytes with relatively low concentrations of ubiquinone Q10 can prevent apoptosis after ArF excimer laser irradiation. If these findings are confirmed on human keratocytes this treatment could be usefully exploited in the PRK surgical procedure. That might lead to a reduction in the occurrence of haze and curvature regression triggered by programmed cell death.

Abstract
We have studied the regeneration of T cell subsets and function after BMT in 21 children affected by combined immunodeficiency after BMT. In the first months, the striking predominance of CD4+ cells displayed the primed CD45R0+ phenotype and a high number of activated (HLA-DR+) T cells were observed. Regeneration of naive CD4+CD45RA+ cells correlated with the recovery of proliferative responses to mitogens (r = 0.64, P<0.001). Peripheral blood lymphocytes circulating after BMT undergo an increased process of in vitro cell death, resulting from two mechanisms: spontaneous apoptosis (SA), a consequence of defective production of IL-2 and down-regulation of Bcl-2 (P = 0.02 vs. healthy controls), and high susceptibility to activation-induced cell death (AICD) after restimulation with mitogens. In accordance with the role of CD95/Fas in this latter process, we have observed a high level of CD95 expression (P<0.001 vs. healthy controls), correlated with AICD (P<0.001) but not with SA, and decreasing with time after BMT (P<0.001). Both SA and AICD levels correlated with the presence of activated T cells and decreased with the progressive recovery of T cell proliferative response. Therefore, the lymphocyte hyperactivated status might explain their susceptibility to apoptosis and contribute to the genesis of immunodeficiency that follows BMT.

Abstract
We report the case of a boy with low expression of HLA class I molecules on peripheral blood mononuclear cells, which is associated with immunodeficiency. The patient, who had a Marfan-like phenotype, had chronic deep skin ulcers and sinobronchiectasis. Immunohistologic examination of the ulcerated skin showed a dense perivascular infiltrate composed of normal mature lymphocytes and macrophages. All cells in the infiltrate showed an apparently normal expression of HLA class I molecules, but intraepidermal dendritic Langerhans' cells were negative for CD1a, an antigen that is a highly specific marker for these cells and is abundantly expressed in some self-healing forms of cutaneous lesions. It is therefore speculated that a defective expression of CD1a molecules can contribute to the chronic persistence of deep skin ulcers, which have already been reported in association with defective expression of HLA class I molecules.

Abstract
The authors make a review about the indications and benefits of the use of nitrates in the treatment of acute and chronic cardiac failure, considering their use for a short and a long period. The advantages are reported, showing the reduction of pulmonary capillary wedge pressure and the increase of systolic output and consequently of the cardiac eject. This effect may be traceable both to the benefic effect on the mitral valve (perhaps incontinent), that in the pericadic "contraist". The reduction of the filling pressures increases the tolerance to the effort, delays the choice of the time for cardiac transplant and prolongs the survival with amelioration.

Abstract
The aortic dissection is a relatively infrequent, but very serious event, that needs to be always considered when a thoracic pain with symptoms of ischemia belongs to the origin of the dissection without signs of myocardial infarction. The most simple and commonly accepted classification, includes two variants, according to the Stanford University (A and B). This aspect is very important in order to the treatment which must be preceded by a suitable pharmacological approach followed in any case by the surgery. We outline the importance of the fast diagnostic knowledge and of the therapeutic choice in order to reduce the mortality that is still very high.

In this paper we outline the importance or the histamine in the genesis of cardiac arrhythmias. Such an event can verify not only in patients with allergic diseases especially versus specific substances (antibiotics and anesthetics), but also after endoscopy of surgery which make free a large amount of histamine. For this reason, we outline the possible evenience anaphilaxis after coronarography or cardiac surgery with extracorporeal circulation. Therefore it is always very important to modulate the histamine tone to avoid arrhythmias which can be serious.

Abstract
Psittacosis marked by liver and spleen involvement and minimal pericarditis was observed in an 18-year-old patient hospitalized for fever of 1 month duration. At admission, there was no other clinical manifestation and the chest X-ray showed no sign of pulmonary involvement. Liver tests revealed cholestasis. Ultrasonography of the abdomen revealed multiple nodular formations in the liver and spleen, images confirmed on computed tomography. Liver biopsy showed granulomatous with hyperplasia of the Kupffer cells surrounded by healthy tissue. Complement fixation to psittacosis antigen was positive and increased significantly over a 15-day interval. Treatment with tetracycline led to rapid remission of the fever and normalization of the liver tests and hepatic images. Liver involvement in psittacosis is not uncommon, but this is apparently the first case reporting echographic anomalies. The absence of pulmonary involvement has been reported earlier in a few cases. The diagnosis is usually suggested on the basis of epidemiologic criteria and confirmed by complement fixation.

Abstract
Systemic Sclerosis (SSc; scleroderma) is associated with several immunological abnormalities, including altered proportion between lymphocyte subsets. Peripheral blood lymphocyte subsets from 25 patients with SSc were studied by two-colour flow cytometry using monoclonal antibodies against CD45RA and CD29 markers, which allow a dissection of CD4+ and CD8+ populations into 'naive' and 'memory' subsets. A decrease of the percentage of CD8+ (p < 0.05) and of CD8+CD29+ (p < 0.001) cells was observed compared to that in 20 age and sex-matched controls. These abnormalities were not significantly associated with the extension of cutaneous disease or other clinical features of SSc nor with treatment, pattern of autoantibodies or HLA phenotype.

Abstract
The frequent combination of chronic antral gastritis with the presence of Helicobacter pylori has been known for ten years. On the basis of studies carried out so far, Helicobacter gastritis is very infrequent in patients suffering from AIDS with digestive pathology. Our study of 317 patients with AIDS confirms the low incidence of this disorder which leads to the conclusion that the treatments intended to combat HIV are apt to modify the physico-chemical conditions of the stomach thus impeding Helicobacter colonization.

In this paper, we have considered the indications for coloscopy for the screening of colon polyposis. On the basis of its sensitivity in detection and follow-up of colo-rectal cancer, we tried to determine the exact procedure to be followed subsequent to the discovery and ablation of a polyp. We have outlined the following parameters to be observed during the period of follow-up: dimension, number, histologic features of the polyp, age, general conditions and familiarity of the patient for colorectal cancer.

Abstract
In this paper the authors review the main prokinetic drugs analyzing their pharmacological properties, therapeutic indications and adverse effects. In addition, some more recently introduced substances are taken into consideration which, although they were not initially used for digestive tract dyskinesias, can nevertheless be used in certain conditions. From this point of view, calcium blocking agents employed in spastic conditions of the esophagus and the new antiserotoninergic drugs for treatment of anticancer chemotherapy-induced vomiting are of particular interest.

Abstract
The above study is an analysis of different dyspeptic syndromes outlining their pathophysiology and clinical features. On this basis, the authors suggest a diagnostic strategy, stressing the importance of certain elements such as age at onset, duration and variability of symptoms. This allows to evaluate the indications for endoscopy or biopsy, or to decide that it is sufficient to continue observation while reassuring the patient that the dyspeptic condition is benign.

Abstract
UNLABELLED A retrospective study on germ cell tumors on children is reported. The purpose of this study was to evaluate some prognostic factors (age, sex, site, histology, treatment) as well as to compare the casistic of Puglia Region with the results of the National literature. 45 patients (30 females, 15 males) aging 2 days-12 years observed in three Pediatric Centres of Bari into 23 years. Primary site of the tumor was: ovary 9, testis 9, sacrococcygeal 16, and others site 11 (head 4, mediastinum 2, pelvis 2, abdomen 2, gluteus 1). HISTOLOGY teratoma 31, choriocarcinoma 1, embryonal carcinoma 7, endodermal sinus tumor 5, germinoma 1. TREATMENT surgery 35 patients, surgery+chemotherapy 6, surgery+chemotherapy+radiotherapy 4. Results of treatment: 37 of 41 valuable patients achieved a response (34 complete, 3 partial response); 4 patients had no response. Of the 37 patients that have had a complete or partial remission, 8 subsequently relapsed; of these 8 patients, 5 obtained a second remission after second line therapy, 3 are dead for progressive disease. Better prognosis was observed in children with gonadal tumors treated with surgery alone.

Abstract
Surgical treatment is warranted only once medical management has proved unsuccessful and should preferably be preceded by psychological evaluation of the patient. So far, surgery has yielded few convincing results in view of the high percentage of failures. After surgery, many patients complain of abdominal pain and diarrhea. The contribution of surgery is highly important in patients suffering from "outlet obstruction", "inertia coli" or Hirschsprung's disease in whom myectomy or Duhamel's operation yield good results.

Abstract
With reference to recent data reported in the literature, the authors stress the importance of new techniques for the diagnosis and management of gastrointestinal villous adenoma. This is a comparatively infrequent tumor which usually occurs in adults above the age of 50 and has no familial incidence. The tumor is apt to evolve towards malignancy. Radiology, and more recently endoscopy permit to ascertain the diagnosis. Endoscopic resection is the treatment of choice while surgical ablation is indicated in sessile or extensive forms.

Abstract
The assessment of chronic pharmacological treatment of stable angina requires serial exercise stress testings. It is well known that exercise tolerance can be improved by the training effect of performing repeated testings. Our study investigated the values of heart rate, systolic blood pressure, rate-pressure product, and duration of exercise at 0.1 mV ST depression during exercise and the same parameters plus the maximal ST-segment depression at peak exercise, collected from three different tests. The first and second were performed at one-week intervals before, and the third (75 days after the first), was performed after a double-blind study with a drug versus placebo. We found a significant increase of exercise duration at 0.1 mV ST depression and at peak exercise, while 6 of 12 patients increased exercise duration from the second to the third test. Individual variability of exercise duration showed increasing values, ranging from 0 to 71% (first vs. third test). In contrast, the ratio of heart rate and systolic blood pressure did not differ between the tests. Our data criticized the use of mean values of exercise time for pharmacological studies; moreover, individual variability could affect results independently of drug or placebo administration. These findings should be taken into account in order to exclude misleading results.

Abstract
Both early onset and late onset type II diabetes were present in one family of nine siblings. The three early onset type II diabetic siblings showed severe microvascular complications: proliferative retinopathy, diabetic nephropathy, and peripheral neuropathy. Early onset type II diabetes was not associated with any particular HLA haplotype. Early onset type II diabetes could be considered a clinical and genetic disease entity different from MODY type diabetes.

Abstract
Eighty systemic lupus erythematosus (SLE) patients attending 3 clinical centers were evaluated immunologically and immunogenetically. No HLA class II antigens were found to be significantly associated with SLE in these patients. A highly significant (P = 6.17 x 10(-7) association was observed between anticardiolipin antibodies and DR7. A lesser association (P less than 0.025) was also observed between DR2 and/or DR3 and anti-Ro (SS-A) antibodies. No relationship was found between any DR antigen and anti-Sm/RNP, anti-double-stranded DNA, or anti-La (SS-B) antibodies.

Abstract
The authors performed a long-term, double-blind, crossover, randomized study on the effects of two drugs (atenolol, 100 mg/day, or nifedipine, 10 mg t.i.d.) when administered alone or in combination on the exercise tolerance in 10 patients with stable angina on effort (mean age 52 +/- 4 years, 8 males and 2 females) and documented significant (greater than or equal to 70%) obstructive coronary lesions at angiography. None of the drug treatments improved exercise duration or maximal sustained work load. Atenolol decreased significantly ST segment depression to -1 +/- 0.8 from -1.91 +/- 0.7, baseline and -2.05 +/- 0.5, placebo. Nifedipine was not better than placebo. The atenolol plus nifedipine treatment was better than placebo (p less than 0.001) or nifedipine alone (p less than 0.05) but was not more significantly efficacious than atenolol alone. Long-term management of exertional angina can be usefully performed using atenolol. The use of nifedipine at the present dose of 10 mg, although well tolerated, did not improve the ST signs of ischemia.

Abstract
We performed HLA typing in 96 couples affected by recurrent abortion "sine causa". We matched these patients with 124 fertile couples and 204 individuals random paired. No significant difference in HLA sharing was demonstrated in the three study groups. The statistical analysis denoted significant differences in regard to HLA A3, A24, B12, and DR- comparing patients and normal members of fertile couples. The frequencies of HLA Cw5, Cw6 and DR2 were different in patients when compared with their partners.
