Primary antiphospholipid syndrome: a report of two pediatric cases

Two cases of primary antiphospholipid syndrome are described. A girl presented with myocardial infarction at the age of 6. afterward developed chorea, livedo reticularis, thrombocytopenia and circulating lupus anticoagulant (LAC). A boy, age 7, had an episode of intracranial hypertension and a deep venous thrombosis of a lower left limb, both recurrent in the following years. A high titer of IgG anticardiolipin antibodies (aCI) was detected. These observations suggest that both LAC and aCI tests should be performed in children with thromboembolic phenomena when the criteria for a definite autoimmune disease are lacking.     

A registry-based study of follow-up failures in the screening experience of cervical cancer patients

Amadori A, Gentilini P, Bucchi L, Innocenti MP, Falcini F, Martini F, Fabbri M, Liverani M, Danesi S, Piantini B, Milandri C, Saragoni L, Amadori D. A registry-based study of follow-up failures in the screening experience of cervical cancer patients. Int J Gynecol Cancer 1998; 8 : 251–256.
Although all components of cervical screening are at risk of error, most studies of the previous screening experience of cervical cancer patients addressed only the false negative cytology results. Other reports showed the importance of screening failures not attributable to the Pap smear. We studied the relative frequency of all types of error observed in the screening history of 115 cervical cancer cases (median age, 60; range, 23–89) registered with the population-based Romagna Cancer Registry in Forlì (northern Italy) between 1986 and 1993. For each case, a search was made for all cytology, colposcopy, biopsy, and treatment reports issued prior to diagnosis. Eighty-one (70.4%) patients had never had a Pap smear. Eight (7.0%) were diagnosed at their first test. Twenty-six patients (22.6%) had had at least one previous smear. Among these, 10 were screened during the five years prior to diagnosis: three patients had false negative cytology results, one patient did not comply with the recommendation for an early repeat smear, two patients with positive cytology results underwent colposcopy with considerable delay (7 and 9 months), one patient had a negative colposcopy (without biopsy), and three patients had biopsies histologically reported as negative. An overview of the registry-based studies of screening histories reported so far from Italy (total number of cases 262) demonstrated that patients with serious shortcomings in follow-up after smear test, colposcopy, biopsy, clinical assessment, and treatment accounted for a substantial proportion of screening failures.     

Risk of cancer other than Kaposi's sarcoma and non-Hodgkin's lymphoma in persons with AIDS in Italy. Cancer and AIDS Registry Linkage Study.

Record linkage was carried out between the national Registry of AIDS and 13 Cancer Registries (CRs) covering, in 1991, about 15% of the Italian population. Observed and expected numbers of cancers and standardized incidence ratios (SIRs) were assessed in 6067 persons with AIDS, for a total of 25,759 person-years. Significantly increased SIRs were found for Hodgkin''s disease [8.9, 95% confidence interval (CI) 4.4-16.0], in which seven of 11 cases were of mixed cellularity type; invasive carcinoma of the cervix uteri (15.5; 95% CI 4.0-40.1); and non-melanomatous skin cancer (3.0, 95% CI 1.3-5.9), in which five of eight cases were basal cell carcinoma. An excess was also seen for brain tumours, but this may be partly due to misdiagnosis of brain non-Hodgkin''s lymphoma or other brain diseases occurring near the time of the AIDS diagnosis. The risk for all cancer types, after exclusion of Kaposi''s sarcoma (KS) and non-Hodgkin''s lymphoma (NHL), was approximately twice the general population risk. An increased SIR for Hodgkin''s disease in persons with AIDS is thus confirmed, though it is many times smaller than that for NHL. An association with invasive carcinoma of the cervix is also shown at a population level. The excess of non-melanomatous skin cancer seems to be lower than in transplant recipients.     

Outcome of primary antiphospholipid syndrome in childhood

The objective of this paper is to investigate the long-term outcome of primary antiphospholipid syndrome (APS) in the paediatric age. The features of unselected patients with primary APS who had disease onset before the age of 16 years were retrospectively analysed in three Italian referralcentres. Clinical and laboratory manifestations were assessed to establish whether, at the end of follow-up, the final diagnosis was still primary APS or whether they had developed definite SLE or lupus-like syndrome. Fourteen patients, nine boys and five girls, who had the presenting clinical manifestation of APS between three and 13 years of age (median nine years) and were followed for two to 16 years (median six years). Six patients presented with deep vein thrombosis, five with cerebral stroke, two with peripheral artery occlusion and onewith myocardial infarction. During follow-up, four patients had one or more recurrences of vascular thrombosis. At last observation, 10 patients could still be classified as having primary APS, two had developed SLE, one lupus-like syndrome and one Hodgkin's lymphoma. In conclusion; our analysis suggests that some children who present with the features of primary APS may progress to develop SLE or lupus-like syndrome.     

Prevalence and clinical significance of anti-cyclic citrullinated peptide antibodies in juvenile idiopathic arthritis

BACKGROUND: Antibodies against cyclic citrullinated peptide (anti-CCP) are considered to be specific for rheumatoid arthritis (RA). OBJECTIVE: To assess the clinical significance of anti-CCP in a cohort of patients with juvenile idiopathic arthritis (JIA). METHODS: Anti-CCP were tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 109 patients with JIA (30 boys, 79 girls), with a mean age of 8.7 years (range 0.6-20.3) and mean disease duration of 3.6 years (range 3 months to 15.6 years). As control groups, anti-CCP were also tested in sera of 30 healthy children, 25 patients with juvenile onset systemic lupus erythematosus (SLE), and 50 adult patients (30 with RA, 20 with SLE). RESULTS: Positive anti-CCP values were found in sera of two patients with JIA (2%), one with polyarthritis, and one with oligoarthritis. Statistical analysis showed that anti-CCP were not associated with the presence of antinuclear antibodies, raised erythrocyte sedimentation rate, or erosions. In the control groups, none of the patients with juvenile onset SLE and only one of 20 adults with SLE were positive for anti-CCP, but 19/30 (63%) adults with RA showed anti-CCP positivity. CONCLUSIONS: Anti-CCP can be detected in children with JIA, but are less frequently present than in adults with RA.     

Influence of a metaphylactic treatment with Baycox® Bovis on the reproductive performances of Fresian heifers: a preliminary study

A blind, randomised, controlled, multicentric field trial was conducted to assess the influence of a metaphylactic treatment with an oral solution of toltrazuril on some reproductive parameters of Italian Fresian heifers during the first 18–20 months of life. For this goal 40 calves were selected from two dairy farms and randomly divided into two homogeneous groups: MTol, treated with toltrazuril and NegC, left untreated. The calves were clinically and coprologically examined over the entire study period. The body condition scores, the body weights and the age at the first service were recorded and compared between the two groups, in addition to some other reproductive parameters including number of pregnancies, average service per pregnancy, conception rate, conception rate at first service and post first service conception rate. The analysis of the results showed that the metaphylactic treatment with toltrazuril influenced positively the average age of the first service (MTol 461.4 days versus NegC 485.45 days), the overall conception rate (MTol 95 % versus NegC 85 %), the success at first (MTol 60 % versus NegC 45 %) and second (MTol 75 % versus NegC 45 %) services and, consequently, the mean number of services to be carried out for each animal (MTol 1.4?±?0.6 versus NegC 1.6?±?0.79). Furthermore, the results confirmed that toltrazuril treatment, applied in accordance with the epidemiological aspects of each farm, is highly efficacious in persistent reduction of oocyst excretions with particular reference to Eimeria zuernii, Eimeria bovis, considered to be mainly responsible for clinical coccidiosis.     

Lymph node pick up by separate stations: Option or necessity

AIM: To evaluate whether lymph node pick up by separate stations could be an indicator of patients submitted to appropriate surgical treatment. METHODS: One thousand two hundred and three consecutive gastric cancer patients submitted to radical resection in 7 general hospitals and for whom no information was available on the extension of lymphatic dissection were included in this retrospective study. RESULTS: Patients were divided into 2 groups: group A, where the stomach specimen was directly formalinfixed and sent to the pathologist, and group B, where lymph nodes were picked up after surgery and fixed for separate stations. Sixty-two point three percent of group A patients showed 16 retrieved lymph nodes compared to 19.4% of group B(P 0.0001). Group B(separate stations) patients had significantly higher survival rates than those in group A [46.1 mo(95%CI: 36.5-56.0) vs 27.7 mo(95%CI: 21.3-31.9); P = 0.0001], independently of T or N stage. In multivariate analysis, group A also showed a higher risk of death than group B(HR = 1.24; 95%CI: 1.05-1.46).CONCLUSION: Separate lymphatic station dissection increases the number of retrieved nodes, leads to better tumor staging, and permits verification of the surgical dissection. The number of dissected stations could potentially be used as an index to evaluate the quality of treatment received.     

Disentangling the Roles of Mammographic Screening and HRT in Recent Breast Cancer Incidence Trends in Italy by Analyses Based on Calendar Time and Time Since Screening Activation

Abstract: The aim of the study was to evaluate the roles of screening activation and hormone replacement therapy discontinuation on the recent declining breast cancer incidence trends in Italy. We analyzed 41,358 invasive female breast cancers incident during 1991–2004 in six Italian population‐based cancer registries. Overall and age‐specific incidence trends were evaluated using Joinpoint analysis. In addition to calendar years, data were analyzed on a years‐since‐screening‐activation basis. Annual percentage change of standardized rates was computed. There were statistically significant increasing trends for women 40–44 and 45–49 years that did not change after screening activation. On the contrary, for women 50–69 years old and for those 70+ years, the increasing trends flattened around 2 years after screening activation. The prevalence of hormone replacement therapy use in Italy is and was rather low. In conclusion, the recent tendency toward stabilization observed in Italy for female breast cancer incidence rates in women aged 50 years or more follows the introduction of mammographic screening.     

Emerging potentials for an antioxidant therapy as a new approach to the treatment of systemic sclerosis

Oxidative stress, favoring disease progression by a rapid degeneration of endothelial cell function is deeply involved in Systemic Sclerosis (SSc) pathogenesis. Raynaud's phenomenon (RP), present in 90% of patients with SSc, provoking frequent daily episodes of hypoxia-reperfusion injury, produces several episodes of free radicals-mediated endothelial derangement. These events results in a positive feedback effect of luminal narrowing and ischemia and therefore to the birth of a vicious cycle of oxygen free radicals (OFR) generation, leading to endothelial damage, intimal thickening and fibrosis. Thus ischemia and reperfusion are two criticals events that may induce oxidative stress and inactivation of antioxidant enzymes. In RP and SSc, a reduced concentration of ascorbic acid, alpha-tocopherol and beta-carotene as well as low values of Selenium have been reported. This antioxidative potential deficiency increases the propensity to oxidative stress. favoring the development of injury mediated by OFR. We reviewed several antioxidant compounds, aiming at their capacity of reverting endothelial dysfunction and damage, scavenging lipid peroxidation and reducing multiple episodes of hypoxia-reperfusion injury. In order to interrupt SSc vicious cycle, we propose a main strategy for SSc treatment by a supplementation of antioxidants and different kind of drugs with antioxidant property, such as Lazaroids, Resveratrol, Melatonin and Probucol.
