RESUMO

The authors describe a rare case of primary ovarian fibrosarcoma and the latest trends in diagnosis and therapy. The rarity of this dis-ease and the scarce number of reported cases pose serious problems in differentiating it from other fibrous forms. A 58-year-old woman presented intermittent pelvic pain and a demarcated, mobile, and solid lump in the right adnexa. Diagnostic imaging revealed a solid- cystic inhomogeneous mass occupying the right adnexa and the CA125 level was elevated. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy and infracolic omentectomy. Histological findings with immunomarkers led to the final diagnosis of low-grade malignant mesenchymal neoplasm derived from the ovarian stroma compatible with fibrosarcoma. Twenty-four months follow-up showed no recurrence of disease. Ovarian fibrosarcoma is very uncommon neoplasm with a poor prognosis. Despite the efforts of several authors in reporting morphological, histological, and immunohistochemical features of this neoplasm, nowadays, the diagnosis, treatment, and prognosis are unresolved issues. The present case highlights the important role of immunohistochemistry to define histological type and differential diagnosis. As demonstrated by the authors' experience, they believe that surgery is curative in the early stages with low immunohistochemical positivity for ki67 and that chemotherapy should be reserved in advanced stages with regimens in use for the treatment of sarcomas.

RESUMO

OBJECTIVE: To evaluate the effects of infection in multiple types of high-risk human papilloma virus (HPV) in cervical preneoplastic lesions in patients undergoing colposcopy following a diagnosis of atypical squamous cells of unknown significance (ASCUS) and low-grade squamous intraepithelial (LSIL) cytology. MATERIALS AND METHODS: Between 2009 and 2010, 2,500 patients were recruited with a mean age of 35 +/- 5 years. Screening for cervical cancer was performed and in case of ASCUS and LSIL the patients underwent colposcopy. The tests for the detection and typing of viral DNA (HPV - DNA test) were performed on cervical swab with real-time PCR amplification. RESULTS: The prevalence of infection was 70% (1579/2256) in the patients recruited. In relation to the degree of preneoplastic lesions some high-risk HPV viral genotypes were identified: HPV 16 (319/1466), HPV 18 (164/1466), HPV 45 (76/1466), HPV 31 (215/1466), HPV 52 (145/1466), HPV 58 (55/1466) HPV 56 (79/1466), HPV 51 (110/1466), HPV 6(138/1466), HPV 11 (88/1466), HPV 42 (34/1466), HPV 53 (43/1466). In case of high-grade lesions of CIN (CIN2 and CIN3) a greater HPV co-infection was detected and in particular the association from 16 to 18 (70%), 16-33 (18%) and 16 to 52 (12%). CONCLUSIONS: Infection caused by the simultaneous presence of multiple HPV genotypes appears to be associated with a significantly increased risk of high-grade lesions of CIN or invasive cancer than the presence of single viral infections. The infection with multiple HPV types is a significant risk factor for high-grade lesions of CIN in women undergoing colposcopy for ASCUS cytology/LSIL. The use of real-time PCR has shown the ability not only to identify the different types of HPV, but also to monitor quantitatively the same over time, and during the study phase, to evaluate the sensitivity and specificity of the method in comparison with other techniques.

RESUMO

OBJECTIVES: to investigate whether body mass index (BMI), hypertension (HTN), diabetes, age, and physical activity can be considered risk factors for endometrial simple hyperplasia in premenopausal women. Furthermore this study was undertaken to determine whether serum concentration of leptin in patients with BMI>or= 30 kg / m2 with endometrial hyperplasia deviate from values in patients with normal endometrium. MATERIALS AND METHODS: The authors enrolled 167 hyperplasia cases and 282 controls. Demographic characteristics and data on age, diabetes, hypertension, BMI, physical activity, and anthropometric parameters were collected. Leptin concentration in serum was measured with immunoenzymatic test kit from IBL. Univariable and multivariable analysis were performed to verify the association among age, HTN, BMI, physical activity, diabetes, and the presence of uterine hyperplasia. Furthermore the authors evaluated the correlation between BMI and leptin level (with Pearson's linear correlation) in women with simple hyperplasia and in controls. RESULTS: The prevalence of hyperplasia found was 34.4%. The following factors were independently associated with increased risk of endometrial hyperplasia: HTN (odds ratio 3.19, 95% confidence interval 1.20-8.48, p<0.020) and BMI>or=30 Kg/m2 (odds ratio 6.43, 95% confidence interval 3.92-10.53, p<0.000). Mean leptin concentration in serum was higher in patients who had endometrial hyperplasia than in controls (p<0.005) and the leptin levels depended on BMI. CONCLUSIONS: The following are risk factors for endometrial hyperplasia in premenopausal women: BMI>or=30 kg/m2 and HTN (blood pressure>or=130/85 or in therapy). Leptin appears to participate in proliferative processes of the endometrium, depending on BMI. Current guidelines may need to be reconsidered.

RESUMO

AIM: To evaluate feasibility, tolerability and cosmetic outcome of intra-operative radiation therapy (IORT) as an exclusive post-surgery treatment of early stage breast cancer. PATIENTS AND METHODS: From October 2008 to October 2009 30 patients underwent wide breast cancer excision or quadrantectomy followed by IORT on tumor bed with accelerated electrons at the dose of 21Gy. The characteristics of the patients were: ductal breast cancer or invasive lobular cT1, cT2 ≤ 2,5 cm, cN0, G1-2, age over 35 years, M0. RESULTS: The average age was 51.7 (range 38 - 75) with an average follow up of 11.7 months (range 6 - 18). The pathologic stage of the lesions resulted pT1 in 29 cases (96,6%), in particular: one case pT1a (3,3%), 21 cases pT1b (70,0%) and 7 cases pT1c (23,3%). One case (3,3%) was pT2 with a diameter of 2.5 cm. The grading was G2 in 20 cases (66,6%) and G1 in 10 cases (33,3%). The toxicity, evaluated according to the EORTC-RTOG criteria, was G0 (33.3%) in 10 cases, G1 (63,3%) in 19 cases, G2 in one case (3,4%); there was no G3 toxicity. The time needed for a complete healing of the wound was less than 10 days in 96,7% of the cases, with one case of limphocele (3,3%). There were no infections of the surgical wound nor any mastitis, neither in the treated quadrant nor in the other ones. We observed a light fibrosis in 5 cases (16,6%), moderate in 2 cases (6,6%) but never severe. Cosmetics, evaluated in four levels, according to Danoff et al., was excellent in 3 cases (43,3%), good in 15 cases (50%), sufficient in 2 cases (6,7%), never insufficient. As regards local control, there was no local relapse. The global survival was 100%. CONCLUSIONS: The IORT in early breast cancer, at the doses used in this study, proved itself as a secure technique, repeatable, with limited complications. The advantages of its use are the possibility of a direct control, by the surgeon and the radiotherapist, of the structures to treat and those to protect; the absence of time needed for cellular repopulation between surgery and radiotherapy; a good cosmetic outcome; and logistic advantages. It is necessary to have a long term follow up to evaluate the efficacy in terms of long term cosmetic and local control.

RESUMO

This work aims to study seeds of the endemic species Astragalus aquilanus from four different populations of central Italy. We investigated seed morpho-colorimetric features (shape and size) and chemical differences (through infrared spectroscopy) among populations and between dark and light seeds. Seed morpho-colorimetric quantitative variables, describing shape, size and colour traits, were measured using image analysis techniques. Fourier transform infrared (FT-IR) spectroscopy was used to attempt seed chemical characterisation. The measured data were analysed by step-wise linear discriminant analysis (LDA). Moreover, we analysed the correlation between the four most important traits and six climatic variables extracted from WorldClim 2.0. The LDA on seeds traits shows clear differentiation of the four populations, which can be attributed to different chemical composition, as confirmed by Wilk's lambda test (P < 0.001). A strong correlation between morphometric traits and temperature (annual mean temperature, mean temperature of the warmest and coolest quarter), colorimetric traits and precipitation (annual precipitation, precipitation of wettest and driest quarter) was observed. The characterisation of A. aquilanus seeds shows large intraspecific plasticity both in morpho-colorimetric and chemical composition. These results confirm the strong relationship between the type of seed produced and the climatic variables.

RESUMO

Although genetic polymorphisms in NOD2 (nucleotide-binding oligomerization domain-containing 2) have been associated with the pathogenesis of Crohn's disease (CD), little is known regarding the role of wild-type (WT) NOD2 in the gut. To date, most murine studies addressing the role of WT Nod2 have been conducted using healthy (ileitis/colitis-free) mouse strains. Here, we evaluated the effects of Nod2 deletion in a murine model of spontaneous ileitis, i.e., the SAMP1Yit/Fc (SAMP) strain, which closely resembles CD. Remarkably, Nod2 deletion improved both chronic cobblestone ileitis (by 50% assessed, as the % of abnormal mucosa at 24 wks of age), as well as acute dextran sodium sulfate (DSS) colitis. Mechanistically, Th2 cytokine production and Th2-transcription factor activation (i.e., STAT6 phosphorylation) were reduced. Microbiologically, the effects of Nod2 deletion appeared independent of fecal microbiota composition and function, assessed by 16S rRNA and metatranscriptomics. Our findings indicate that pharmacological blockade of NOD2 signaling in humans could improve health in Th2-driven chronic intestinal inflammation.

RESUMO

Inflammatory bowel disease (IBD) is associated with dysregulated macrophage responses, such that quiescent macrophages acquire a pro-inflammatory activation state and contribute to chronic intestinal inflammation. The transcriptional events governing macrophage activation and gene expression in the context of chronic inflammation such as IBD remain incompletely understood. Here, we identify Kruppel-like transcription factor-6 (KLF6) as a critical regulator of pathogenic myeloid cell activation in human and experimental IBD. We found that KLF6 was significantly upregulated in myeloid cells and intestinal tissue from IBD patients and experimental models of IBD, particularly in actively inflamed regions of the colon. Using complementary gain- and loss-of-function studies, we observed that KLF6 promotes pro-inflammatory gene expression through enhancement of nuclear factor κB (NFκB) signaling, while simultaneously suppressing anti-inflammatory gene expression through repression of signal transducer and activator of transcription 3 (STAT3) signaling. To study the in vivo role of myeloid KLF6, we treated myeloid-specific KLF6-knockout mice (Mac-KLF6-KO) with dextran sulfate sodium (DSS) and found that Mac-KLF6-KO mice were protected against chemically-induced colitis; this highlights the central role of myeloid KLF6 in promoting intestinal inflammation. Collectively, our results point to a novel gene regulatory program underlying pathogenic, pro-inflammatory macrophage activation in the setting of chronic intestinal inflammation.

RESUMO

UNLABELLED: The Uruguayan Registry of Glomerulopathies began its activity in 1974 and since 1985 is a national registry. The aim of this report is to analyze the incidence and the variations in frequencies of the histological diagnosis and clinical presentation during the 1980-2003 period. PATIENTS AND METHODS: From the 2,058 patients with renal biopsy in the whole period, we analyzed the histological diagnosis and the following data has been collected when the patients were registered: age, gender, clinical syndrome, proteinuria, hematuria, serum creatinine, blood pressure and time from the first symptom. Four periods of registry entry were considered: 1980-1989, 1990-1994, 1995-1999 and 2000-2003. Chi-square and Student test for independent samples were used to evaluate the differences among the variables frequencies in the four periods. RESULTS: The incidence of registered glomerulopathies per million population (pmp) increased from 13 (1980-1989) to 43 (2000-2003). In the 2000-2003 period, the incidences pmp were: primary glomerulopathy (PG), 25.3 and secondary glomerulopathy, 14.2. The highest incidences pmp were: focal and segmental glomeruloesclerosis (FSGS) 6.4; vasculitis 5.4; lupus nephritis 4.6; minimal change disease (MCD) 4.6; IgA nephropathy (IgAN) 4.5; and membranous nephropathy (MN) 4.0. The most frequent PG were the FSGS (29.3%) and the MCID (19.6%). The FSGS frequency decreased from 36.3% in 1995-1999 to 19.1% in 2000-2003. The IgAN frequency increased from 5.2% in 1980-1989 to 17.5% in 2000-2003. Nephrotic syndrome was the most frequent clinical presentation; its frequency was over 30% in the four periods. Asymptomatic urinary abnormality frequency increased from 14.0% in 1980-1989 to 22.7% in 2000-2003. The frequency of serum creatinine under 1.5 mg/dl, increased from 42.2% in 1980-1989 to 67.2% in 2000-2003 (p = 0.001). The frequency of serum creatinine over 6.0 mg/dl, decreased from 19.3% in 1990-1994 to 7.2% in 2000-2003. The percentage of patients referred since the first month of the apparent onset of the disease increased from 24.0% in 1980-1989 to 40.1% in 2000-2003 (p < 0.001). CONCLUSIONS: In Uruguay, the incidence of glomerulopathies with histological diagnosis has increased and the frequency of the different types has changed. Several indicators seem to show that the reference of patients to the nephrologist tended to be earlier in the last years.

RESUMO

Little information is available on asymptomatic carriage of Cryptosporidium in immunocompetent and immunodeficient children. We prospectively studied a group of asymptomatic children, 78 immunocompetent and 50 immunodeficient, to document the incidence of asymptomatic carriage of cryptosporidiosis in such a population. We also investigated whether the treatment of children who carried asymptomatic cryptosporidiosis could help in reducing their risk of gastrointestinal symptoms as well as the shedding of infectious oocysts. The occurrence of multiple infections with common intestinal pathogens including Giardia lamblia was also investigated. Asymptomatic cryptosporidiosis was documented in 6.4% of immunocompetent and 22% of immunodeficient children. In a control symptomatic population Cryptosporidium was found in 4.4% of immunocompetent and 4.8% of immunodeficient children. Asymptomatic carriage of Cryptosporidium was documented in 2 human immunodeficiency virus-infected children, one of whom also carried Giardia asymptomatically. Treatment with spiramycin (100 mg/kg daily for 14 days) reduced significantly the duration of the shedding of potentially infectious oocysts. Finally no gastrointestinal symptoms developed in children treated for asymptomatic infection with Cryptosporidium, whereas children who were not treated developed gastrointestinal symptoms.

RESUMO

In a large number of patients suffering from breast carcinoma the surgeon is still forced, for strictly technical reasons and/or by the patient's choice, to perform a radical operation that psychologically and practically compromises the quality of life of the patient, in varying degrees from patient to patient. The authors have analyzed the main characteristics of BR from the esthetic-functional, psychological, and oncological points of view, in the light of a careful examination of the literature and of the data relating to a sample group of 500 BR treated according to a protocol in which BR has been included, with times and modalities depending on the histological type of tumor and the level of local evolution of the disease. The variety of BR techniques available is such as to permit this option in a great variety of cases. Whenever possible, immediate BR, with placement of a breast prosthesis at the same time or after positioning a tissue expander, is to be preferred. If additional skin or muscle is needed, BR is to be performed at a later time by means of more complex techniques (latissimus dorsi myocutaneous flap plus prosthesis, TRAM flap, free flap). When performed after adequate evaluation and in a technically valid way, BR gives good esthetic and psychological results, has a low incidence of complications or sequelae, and does not affect the natural history of the disease; in particular, BR does not change the percentage of local recurrence or its early diagnosis and allows adequate multidisciplinary treatment.

RESUMO

The rapidity and efficacy of a short course of liposomal amphotericin B was evaluated in 29 children affected by visceral leishmaniasis (Leishmania infantum). Their overall health status was assessed using the prognostic inflammatory and nutritional index (PINI), and their haematological status by the reticulocyte count and haemoglobin blood levels. All these quantities were measured on day 0, and 3 and 10 d after starting therapy. A significant decrease of inflammatory signs, associated with an improved reticulocyte count, was recorded after 3 d of therapy. A significant increase of haemoglobin levels was also observed 10 d after the start of treatment. The early reduction of inflammatory signs and the improvement of bone marrow function in most patients confirmed the validity of amphotericin B therapy. The PINI score is helpful in assessing the severity of visceral leishmaniasis and the follow-up of its treatment.

RESUMO

Twenty-one operable breast cancer patients were treated with interferon-beta (IFN-beta) at the dosage of 3 x 10(6) IU every other day for a median time of 16 days. Estrogen receptors (ER), progesterone receptors (PgR), labelling index (LI) and DNA ploidy were evaluated on tumour tissue obtained during diagnostic biopsy and surgery, before and after treatment respectively. The study showed a statistically significant rise of ER (18 out of 21 evaluable cases) (p = 0.04) and no influence on ploidy status (8/21) in all evaluable samples. We also noticed a rise of PgR (18/21) and a decrease of LI (10/21 cases), but they were not statistically significant. Moreover, in the patients in whom both determination of ER and LI was possible (10 cases), a significant inverse correlation between the differences pre- and post-treatment was observed (p = 0.016). These preliminary results induce us to study a greater number of patients with the aim to confirm the biological effects of IFN-beta on ER, to clarify the trend of the rise of PgR and the decrease of LI and to analyse the relationship between these parameters.

RESUMO

We investigated the serum fatty acid profiles of cholesterol esters, phospholipids and triglycerides in 24 patients with Friedreich's disease and 16 patients with other forms of spinocerebellar degeneration. In 8 patients with Friedreich's disease we also analyzed the fatty acid profile of the lipoprotein fractions. We found no major differences in fatty acid profiles between ataxic patients and sex and age-matched controls; in particular there was no decrease of linoleic acid in Friedreich's disease. The level of linoleic acid in serum cholesterol esters decreased with increasing disability of patients.

RESUMO

The ability of human breast carcinomas to convert pregnenolone to progesterone and dehydroepiandrosterone to delta 4-androstene-3,17-dione (delta 4) was investigated as a potential aid for prognosis, and the following observations were recorded. 1. Neither the amounts of progesterone or delta 4 synthesized nor delta 4/progesterone ratios correlated with tumour size or lymph node involvement. 2. delta 4 synthesis was lower in carcinomas from patients who had recurrences within 2 years of mastectomy than in carcinomas from those who remained free of metastases. 3. Life table analysis of the results indicated that these parameters appeared unlikely to be useful aids for prognosis.

RESUMO

The effects of administration of opiates and naloxone on the activities of PFK, 6PGDH and alpha-GPDH and alpha-GPDH/6PGDH ratios in human breast carcinomas were investigated in patients awaiting mastectomy. Injection of naloxone or fentanyl into an antecubital vein resulted in a statistically significant reduction in the activity of alpha-GPDH. Fentanyl was also effective in reducing the activity of 6PGDH. Injection of morphine into a branch of the internal mammary artery during mastectomy failed to induce changes in the activities of any of the enzymes but injection of naloxone resulted in a significant rise in the activity of 6PGDH. It is postulated that these alterations in the activities might not be associated with the binding of these drugs to opiate receptor proteins in the carcinoma. Furthermore opiate agonists or antagonists might not produce the required changes in the activities of any of the enzymes.

The effects of neuroadenolysis on plasma titres of beta-endorphin, beta-lipotropin, ACTH, TSH and prolactin have been investigated in five patients with metastatic cancer who responded to the treatment and have been in remission for more than four years and in five others who were undergoing the treatment for the first time for pain due to cancer metastases. beta-Endorphin, beta-lipotropin and ACTH titres were within the normal ranges of values in both categories of patients but post-neuroadenolysis titres of these peptides were higher than those before the treatment. The ability to secrete TSH and prolactin and to respond to thyroid stimulating hormone releasing hormone (TRH) remains intact following the treatment. However, whereas basal TSH titres and response to TRH was lower in the majority of patients, no such effect was observed on prolactin secretion. Plasma titres of prolactin and TSH were below the sensitivity of the method in the five patients who are in remission for more than four years. These preliminary findings suggest that neuroadenolysis probably affects some mechanism(s) associated with the control of beta-endorphin, beta-lipotropin and ACTH synthesis.

RESUMO

The match between ticks and pediatricians in Italy is usually a seasonal event related to the spring and summer trips and to the increasing of outdoor activity that sun and warm weather allow, both for children and ticks. So cared parents reach emergencies asking for tick removal but more often after the tick has yet been removed by empirical manoeuvres and after the killing and the destruction of the "enemy". We have scheduled, in the years 2002-2003, the 167 children that reached our unit for a tick bite; they where 92 males (mean age four years) and 75 females (mean age five years). Two of them had only a questionable tick bite but one had erythema on the lateral side of the left ankle, fever of obscure origin and weakness with generalised malaise. She was six years old and she lived with a dog on which, in more instances, ticks where found, but she never noticed ticks on her body. The dog had positive levels of anti rickettsial and anti borrelia antibodies but no evidence of conclamate illness. In this girl we found high titers of anti borrelia antibodies that WB testing confirmed to be anti B. burgdoferi. We diagnosed Lyme disease and treated the girl with amoxicillin (50 mg/kg/day) for three weeks achieving the complete relief of symptomatology till today. Three children with conclamate tick bite had positive levels of anti Rickettsia conorii antibodies with increasing levels at a twenty days control; two (aged four and five years) of them had a full symptomatology (tache noire, satellite lymphadenopathy, fever, and maculopapular erythema) for Meditarranean spotted fever; the latter (three years old) had an atypical form with the complete absence of maculopapular erythema. The therapy was clarithromycin (15 mg/kg/day) for three weeks. In Campania, in the years 2002/2003 on 167 children with tick bite that reached our unit, we found only four pathological correlable events; so are our ticks not infected? But we don't know how many children where tick bited and if there were other children with Lyme disease or Rickettsial disease because of the lack of a pediatric reference centre for "tick bite diseases" and the incomplete and late diffusion of knowledge on these diseases. Other Italian regions and such as Trentino Alto Adige, Veneto, and Friuli Venezia Giulia had a remarkable officially notified number of cases of Lyme disease and in Sicilia, Sardegna and Lazio there were numerous officially notified Rickettsial diseases. So we hope that Campania may be an happy island but we also think that a more effective cooperation between pediatricians and veterinarians and the creation of regional reference centres for tick bite diseases may arise a surveillance net to prevent the diffusion of these world wide emerging diseases and so that parents can achieve an univoque and useful information, the only way to defeat the fear of ignorance.

RESUMO

In the first half of the 20th century, visceral leishmaniasis (VL) was a common infantile syndrome in coastal territories of the Campania region of Italy. After World War II, the incidence dropped to a few cases/year for three decades; in late 1980s the disease reemerged among both children and adults. To face the VL recrudescence, a Paediatric Reference Centre was established at the Santobono-Pausilipon hospital in Naples, for the clinical diagnosis, care and drug treatment of all infantile VL cases occurred in the Campania region. Rapid laboratory diagnosis was secured by a Diagnostic Reference Centre established at the Istituto Superiore di Sanità. Here, we report on the epidemiological and parasitological features of all cases referred to the Centre in the past 15 years. From 1990 to March 2004, a total of 255 cases were diagnosed and treated at the Centre. The Figure shows the yearly trend of patients (min. 3 cases in 1990 and 1991, max. 30 cases in 2000). There were 135 males (52.9%); the age ranged 4 months-14 years, but 189 patients (74.1%) were < or = 3 years old. The majority of the patients (189, 74.1%) were from the Naples province, with a cluster of 102 cases (40% of total patients) from the towns and districts surrounding Vesuvius. Twenty-seven cases (10.6%) were from the town of Maddaloni, Caserta province, whereas 15 cases (5.9%) were from coastal villages of the Salerno province. Only 1 and 2 cases were from Benevento and Avellino provinces, respectively. All patients but seven, who have been treated with antimonial drugs in the 1990-1993 period, were successfully treated with a liposomal amphotericin B regimen. From bone-marrow aspirate samples, 138 Leishmania cultures were obtained in EMTM and Sloppy Evans' media, of which 134 have been typed by the electrophoretic analysis of 13 isoenzymes. Two zymodemes (Z) of L. infantum were routinely identified over the study period, ZMON-1 (the commonest zymodeme in the Mediterranean area) and ZMON-72, variant from MON-1 in PGM mobility and detected only in our region. The latter, identified in 61 patients (45.5%), was found exclusively distributed in towns of the Vesuvius area and in Maddaloni until 1996, but in recent years it appears to have spread to other areas of the Naples (including the island of Ischia) and Caserta provinces, but not to Salerno province. In conclusion, the VL macrofocus of the Naples-Caserta area is probably responsible for the highest number of infantile cases among any VL macrofoci described in southern Europe. Considering the limited efforts paid to control the canine reservoir, rapid diagnosis and appropriate treatment of patients still remain the first-line control measures aimed at reducing the health impact of the disease.
