RESUMEN

The aim of our study is to identify - in a cohort of obese women - cardiovascular and clinical risk factors in women with previous complicated pregnancies and protective factors in women with previous physiological pregnancies. A total of 135 nonpregnant obese women referring to Policlinico Gemelli in Rome were prospectively collected in 2009-2010. Thirty-two women matched inclusion criteria: 16 reported a previous physiological pregnancy and 16 reported previous obstetric complications. A clinical, instrumental and laboratory evaluation has been performed for each patient. Statistical analysis was performed using StatView Software. Values are expressed as mean ± standard error (SEM). All tests were two-tailed with a confidence level of 95% (p < .05). Statistically significant reduced flow-mediated dilatation (p = .0338), increased serum values of vascular cell adhesion molecule (p = .0154) and higher systolic blood pressure values (p = .0427) have been detected in obese women with previous complicated pregnancies due to gestational diabetes and/or hypertension. In conclusion, obese patients with previous complicated pregnancies develop signs of endothelial dysfunction in the postpartum period. Future research should focus on the early identification of possible molecular mechanisms implicated in the development of glyco-metabolic and cardiovascular diseases in obese patients, since they are at higher risk of metabolic syndrome.

RESUMEN

Postnatal growth restriction and failure to thrive still remain a major problem in Extremely Low Birth Weight (ELBW) infants . The goal for the nutritional care of these infants is to achieve rate of growth similar to those of the fetus in utero at the equivalent gestational age. Human milk fortified remains the best food for all these preterms. Two groups of preterm of weight 580-1250 g and gestational age 23-32 wk, were fed with different protein intake in the human/maternal milk fortified ( 3,5 g Kg-1 per day and 4,8 g Kg-1 per day in the control and intervention group respectively).The feeding tolerance, intrahospital growth, neurological outcome and anthropometric data until 12 months of corrected age, were evaluated. The protein supplemented group (PSG) showed an intrahospital highter growth rate ( mostly in head circumference, p 0,02, and length growth, p 0,04) only in the preterms with 580-980 g and 23-30 wk. In the same preterms, Griffith Development Mental Score at 3 and 12 months corrected age showed higher score than in the control group in the Performance (p 0,04) and Hearing/Language (p 0,03) items. The auxological evaluation in the postdischarge period showed in the PSG group mean z-score values for length higher than those in the control group at 9 (p 0,04) months of corrected age.

RESUMEN

The adverse effects of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) are not limited to the related infectious disease. In children and adolescents, serious risks due to the coronavirus disease 2019 (COVID-19) pandemic are also related to its indirect effects. These include an unbalanced diet with an increased risk of weight excess or nutritional deficiencies, increased sedentary lifestyle, lack of schooling, social isolation, and impaired mental health.Pediatricians should be aware of the side effects of the COVID-19 pandemic on children's diet, physical mental health and advise the families according to their nutritional needs and financial resources. Moreover, the lack of a targeted therapy able to offer protection against the deleterious effects of SARS-CoV-2 infection should require a greater effort by scientific societies to find a more effective prevention strategy. In this context, much interest should be given to nutritional support, able to contrast malnutrition and to stimulate the immune system.

RESUMEN

OBJECTIVE: The aim of the present study is to investigate the correlation between pregnancies complicated by morphological or chromosomal fetal anomalies and an obstetric history of two or more pregnancy losses, analyzing the association with any maternal risk factor. STUDY DESIGN: Retrospective analysis of women who had access to the Day Hospital Clinic of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome from 2012 to 2018 for a pregnancy complicated by fetal malformation and/or abnormal karyotype, and who had an obstetric history of at least one pregnancy loss. Patients were divided into four groups depending on the number of miscarriages and the presence of a genetic anomaly: Group 0 included women with <2 miscarriages and fetal malformations, Group 1 included women with ≥2 miscarriages and fetal malformations, Group 2 included women with <2 abortion, fetal malformations and the presence of genetic anomalies; Group 3 included women with 2 ≥ abortions, fetal malformations and genetic anomalies. Statistical analysis was performed using the SAS v. 9.4 (SAS Institute Inc., Cary, NC, USA). RESULTS: A total of 466 patients were included in the present analysis. Out of these, 379 patients belonged to Group 0; 40 patients entered in Group 1; Group 2 included 42 patients, and 5 patients were part of Group 3. Pregnancies complicated by fetal congenital malformations in patients with two or more pregnancy losses were significantly associated with maternal trombophilic disease and previous birth defects. Recurrent miscarriage and fetal structural anomalies were also significantly correlated with advanced maternal age. CONCLUSIONS: An adequate periconceptional counseling regarding the risk of fetal congenital anomalies may be indicated in patients affected by thrombophilic disease, as well as in those of advanced maternal age and with a pregnancy history of fetal malformations. The screening for thrombophilia may be advisable in patients with an obstetric history of congenital birth defects.

RESUMEN

AIM: Urinary incontinence is a classical sign of childbirth-related perineal trauma, the prevalence of which is estimated, depending on age, at between 10% and 50%. Pelviperineal rehabilitation offers an excellent opportunity to prevent pelviperineal disorders. The aim of the present study was to evaluate the prevalence of urinary incontinence and pelviperineal disorders in the local context, and also that of pelviperineal rehabilitation. METHODS: Of the 1793 women who gave birth in Udine in 2006, 900 primipara and secondipara Caucasians with single term pregnancies dated ultrasonically to be within 20 weeks of gestation, were selected. A total of 602 of them were contacted by telephone and two questionnaires were administered. RESULTS: The prevalence of pelviperineal rehabilitation in our population was 4.49%, while that of pelviperineal disorders was much higher, at around 40.20%. The prevalence of urinary incontinence was due in 27.57% of cases to stress and in 14.45% to urgency, with an overlap in 9.8% of cases and a story of prior incontinence in 9.97%. The prevalence of urinary urgency in women subjected to rehabilitation is significantly lower than in those not treated (P=0.004). Dyspareunia represents 16.11% of cases, coital incontinence 0.33%. One case of gas incontinence emerged but there was no case of faecal incontinence. CONCLUSIONS: Pelviperineal rehabilitation in the observed population has a very low prevalence, especially if compared with the high prevalence of disturbances related to dysfunctions of the pelvic floor during postpartum.

RESUMEN

The term undifferentiated connective tissue diseases (UCTD) is used to identify systemic autoimmune diseases not fulfilling classificative criteria for defined connective tissue diseases (CTD). Aim of the present study was to evaluate the evolution to defined CTD of an historical cohort of 91 UCTD patients followed at our Unit and to describe clinical and serological characteristics of stable UCTD patients with a disease duration of more than 5 years. Patients, previously described, were selected for having an undifferentiated profile after 1 year of follow up. These patients have been regularly followed at our Unit and their diagnosis has been reassessed annually based on the existing classificative criteria. Seven UCTD patients with a follow up of less than 5 years have been excluded from the study, therefore 84 patients (F: 81, M: 3) have been analysed. During the follow up 28 patients (33%) developed a defined CTD. In particular 22 patients developed systemic lupus erythematosus (SLE), while the remaining 6 patients developed other CTDs (2 primary Sjögren's syndrome, 2 overlap syndromes, 1 Systemic Sclerosis, 1 rheumatoid arthritis). The evolution to a defined CTD occurred after a mean disease duration of 80.6+/- 66.8 months (min 14, max 336, median 72); the evolution to SLE occurred after a mean disease duration of 66.8+/-43.3 months (min 17, max 216, median 57). Anti-cardiolipin antibodies were the only variable correlated with the evolution to SLE (p<0.05). Stable UCTD were characterized by a simplified clinical picture with no major organ involvement and by a simplified autoantibody profile (anti-Ro/SSA antibodies and anti-RNP antibodies were the single antibody specificities observed in 22% and 13% of patients respectively). These results confirm previous data showing that about 30% of UCTD patients will develop a defined CTD, the predictive role of anti-cardiolipin antibodies for the evolution to SLE, and the existence of stable UCTD, distinct clinical entities with a simplified clinico-serological profile. The early identification of stable UCTD is very important both from a clinical and a research point of view. Future research is needed to define a new set of classification criteria.

RESUMEN

The term undifferentiated connective tissue diseases is used to define conditions characterized by the presence of signs and symptoms suggestive of a systemic autoimmune disease that do not satisfy the classificative criteria for defined connective tissue diseases (CTD) such as systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), rheumatoid arthritis (RA) and others. A small percentage of patients presenting with an undifferentiated profile will develop during the first year follow up of a full blown CTD, however an average of 75% will maintain an undifferentiated clinical course. These patients may be defined as having a stable undifferentiated connective tissue diseases (UCTD). The most characteristic symptoms of UCTD are represented by arthritis and arthralgias, Raynaud's phenomenon, leukopenia, while neurological and kidney involvement are virtually absent. Eighty percent of these patients have a single autoantibody specificity, more frequently anti-Ro and anti-RNP antibodies. Stable UCTD are considered as distinct clinical entities and therefore it has been proposed to define those conditions as UCTD. Classificative criteria have also been proposed and a work to better define them is still under way.

RESUMEN

The direct antitumoral effects of gonadotropin-releasing hormone (GnRH) analogues on breast tumors have been surmised from clinical observations and in vitro studies. The present study aimed to determine the effects of the GnRH agonist [D-Trp6]GnRH (Decapeptyl) on steps of experimental mammary carcinogenesis, and the mechanisms, other than the chemical castration, involved. We chose a recent model, i.e., mammary tumors induced by wild-type A2 polyoma (Py) virus in BALB/c female nu/nu mice, which displays the following characteristics. Tumors are mammary adenocarcinomas similar to well differentiated breast carcinomas. Tumor promotion period ends 20 days after Py virus inoculation and is estradiol dependent. The first palpable tumors occur 60 days after Py virus inoculation, and tumor growth is ovarian hormone independent. The effects of Decapeptyl treatment on tumor induction and tumor growth were studied in normal or ovariectomized 6-week-old nude mice inoculated with 10(7) plaque-forming units Py virus (day 0 of experiments). Normal mice and ovariectomized mice percutaneously supplemented with 0.6 micrograms 17 beta-estradiol every other day until day 30 (OvE2 mice) were treated with monthly s.c. injections of the sustained release form of Decapeptyl (5 mg/kg) until the end of 180-day experiments. Overall values for latency periods were included within a day 60 to day 130 time interval. Hormone-independent outgrowth was not affected. We focused on tumor progression before the outgrowth. Incidences on tumor appearance kinetics account for effects at this stage. 17 beta-Estradiol repletion strongly antagonized (P less than 0.001) the slowing effect of ovariectomy on the tumor appearance kinetics, indicating that tumor progression is estradiol sensitive in its early stages. [D-Trp6]GnRH treatment antagonized tumor appearance profiles, inducing similar kinetics in both normal and OvE2 mice. In normal mice, the antagonism (P less than 0.01) was concomitant with significant decreases (P less than 0.05) in serum levels of estradiol and prolactin, which are critical hormones for mammary tumor development in mice, suggesting a pituitary-mediated effect. In OvE2 mice, the antagonism (P less than 0.01) occurs independently of estradiol and prolactin, suggesting a direct effect at the mammary cell level. Because of alterations in kinetics, this effect is exerted at the early stages of tumor progression on Py virus-transformed, ovarian hormone-sensitive cells in the mammary tissue. This new animal model of breast cancer is shown to be useful in characterizing direct antitumoral effects of GnRH analogues and studying the basic mechanisms of mammary carcinogenesis.

RESUMEN

RESUMEN El higroma quístico es la malformación del sistema linfático que más frecuentemente se observa en el período prenatal y que se ubica principalmente en el cuello y/o la nuca. Su tasa de detección ha aumentado desde la implementación de la translucencia nucal fetal (TN) en el primer trimestre de embarazo, y su presencia se ha relacionado con anomalías congénitas, aneuploidías, pérdida del embarazo y trastornos en el desarrollo. El objetivo de la presentación de este caso es resaltar la importancia del diagnóstico antenatal del higroma quístico, con el fin de realizar una intervención precoz y evitar la muerte fetal. Se recibe para estudio anatomopatológico, feto de sexo indeterminado producto del primer embarazo de una madre de 19 años de edad sin previos controles prenatales, con presencia de una gran masa quística que se extiende desde el rostro hasta la nuca. Mediante el estudio histológico se confirma el diagnóstico de higroma quístico. Al carecer de análisis de cariotipo no fue posible establecer la preexistencia de alguna anomalía genética. El también conocido como linfangioma quístico, es un tumor vascular benigno cuyo diagnóstico antenatal mediante la ultrasonografía resulta fundamental en la evolución y pronóstico de la enfermedad. Desafortunadamente en nuestro caso, la falta de controles prenatales y la ausencia de estudios ultrasonográficos que permitieran conocer las características de este linfangioma, pudo impactar significativamente en el desenlace fatal.


ABSTRACT The cystic hygroma is the malformation of the lymphatic system that is most frequently observed in the prenatal period and is located mainly in the neck and/or the nape of the neck. Its detection rate has increased since the implementation of fetal nuchal translucency (NT) in the first trimester of pregnancy and its presence has been associated with congenital abnormalities, aneuploidies, pregnancy loss, and developmental disorders. The aim of this case is to highlight the importance of antenatal diagnosis of cystic hygroma in order to perform early intervention and avoid fetal death. It is received, for anatomopathological study, a fetus of undetermined sex product of the first pregnancy of a 19 year-old mother without previous prenatal controls, with the presence of a large cystic mass that extends from the face to the neck. The histological study confirms the diagnosis of cystic hygroma. As there was no karyotype analysis, it was not possible to establish the preexistence of any genetic abnormality. Also known as cystic lymphangioma, is a benign vascular tumor whose antenatal diagnosis by ultrasonography is essential in the evolution and prognosis of the disease. Unfortunately in our case, the lack of prenatal controls and the absence of ultrasonographic studies that would allow knowing the characteristics of this lymphangioma, could significantly impact in the fatal outcome.

RESUMEN

In vitro and in vivo immunologic parameters were determined in 26 patients treated continuously with cyclosporine to prevent graft-versus-host-disease (GVHD) after allogeneic bone marrow transplantation (BMT) for acute and chronic leukemia and for aplastic anemia. A group of 18 patients was tested 6 months after BMT and another group of 10 patients was tested after one year. At 6 months after BMT, 94% of the patients had normal serum IgG and IgM levels, whereas at one year 29% of them had low IgA levels. The proportion of patients with normal lymphocyte responses in vitro at 6 months after BMT was 69% and 76% for the responses to concanavalin A and to soluble antigens; 75% and 53% for the responses to allogeneic cells and pokeweed mitogen, respectively; and 89% for the response to phytohemagglutinin. All but one were able to generate suppressor cells upon con A stimulation. At one year after the graft, only one patient had demonstrable multiple abnormalities in in vitro tests. Skin test reactivity at one year was comparable to pre-graft reactivity. After BMT a lymphopenia persisted for 6 months. The rate of infectious complications was high during the first 3 months after BMT, and it diminished progressively as immune functions returned to normal. Infection was the cause of death in two cases (one disseminated cytomegalovirus infection and one septicemia). GHVD occurred in 12 patients; in nine of them the disease was transient and mild, only 1 patient developed severe chronic GVHD. Acute GVHD did not influence the tempo of immunologic reconstitution. In comparison to other studies, it seems that cyclosporine does not delay immune restoration, or increase morbidity from infection, while preventing GVHD and its complications efficiently.

RESUMEN

A stillborn female with a "de novo" deletion of band 12p13 is described. Her main clinical manifestations are intrauterine growth retardation, unilateral cleft lip, protruding tongue, and small, low set, and posteriorly angulated ears. Comparison of this case with 4 previous reported patients with an isolated distal del(12p) fails to show significant common phenotypic characteristics.

RESUMEN

Anticipation has been described in bipolar affective disorder (BPAD). However, there are conflicting results from association studies screening for a link between BPAD and CAG/CTG repeat expansions, the molecular basis of anticipation in several hereditary neurodegenerative disorders. Here, the repeat expansion detection (RED) method was used to screen for CAG repeat expansion in 119 French BPAD patients. Western blotting was also used to search for polyglutamine stretches, encoded by CAG expansion, among proteins, extracted from lymphoblastoid cell lines, from six selected familial cases. Maximum CAG/CTG repeat length did not differ significantly (P = 0.38) between the 119 BPAD patients and the 88 controls included in the study. Several categories of subgroups were used, none of which showed significant association with a long repeat. Nor was a specific protein with an unusually long polyglutamine stretch (lower detection limit, approximately 33 polyglutamines) detected in cell lysates from the familial cases studied. In conclusion, an association between a long CAG/CTG repeat and BPAD in the French population sample studied was not found. Nonetheless, a short repeat (<40 repeats) might still be implicated, and this possibility warrants further study.

RESUMEN

A decrease in age of onset of schizophrenia through consecutive family generations (anticipation) has been found in several studies. Anticipation is known to result from expansion of CAG repeats in genes that determine several neurodegenerative disorders. In a previous study we analysed 26 unilineal two-generation French pedigrees and found clinical evidence of anticipation. A 10-year mean reduction in age of onset of schizophrenia was found in the second generation compared with the parental generation. The repeat expansion detection method was used to screen for CAG expansion in 21 of the 26 families with evidence of anticipation for the disease and in 59 sporadic schizophrenics and 59 controls. Comparison of the frequency distributions of CAG/CTG repeat size observed in schizophrenics and controls showed no significant difference, even when we considered familial (P = 0.23) and sporadic (P = 0.25) affected individuals separately. These results do not support the association between long CAG repeats and schizophrenia. However, the possibility that expansions with fewer than 40 repeats are involved in schizophrenia cannot be excluded.

RESUMEN

In a prospective naturalistic study many of the 120 patients treated for a current major depressive episode continued to meet the criteria for a major depressive episode as defined by DSM-III during the whole follow-up period (from 1 to 4 years). The problem of compatibility between the chronicity of a full depressive syndrome and the definition of the major depression as episodic with possible relapses or recurrences is discussed. A relationship between chronicity and lack of adequate treatment at onset was found.

RESUMEN

The aims of the present study were to evaluate the extent to which primary care physicians' (PCPs) identification of psychiatric distress is related to a number of nonpsychopathological factors, such as patient sociodemographic and health-related characteristics, and to assess the impact of depression on PCP identification of psychiatric distress, controlling for patient sociodemographic and health-related characteristics. Two patient samples were chosen to explore these issues: 1) patients not fulfilling any ICD-10-defined or subthreshold psychiatric diagnosis and, 2) patients with an ICD-10 diagnosis of current depression. Patients attending 46 primary care clinics during an index period were screened by the General Health Questionnaire (GHQ)-12 and selected for a second stage interview according to GHQ score. Among the 559 interviewed patients, 123 had no mental disorder and 66 had an ICD-10 current depressive disorder. Identification of psychiatric distress by the PCP was associated with retirement among subjects without mental disorders but not among depressed patients. Patient's negative overall health self-perception and severity of physical illness were significantly related to identification of psychiatric distress in the two groups, whereas neither disability nor reason for medical consultation had a significant effect. Patients with current depression, compared with those without, were 4.3 times more likely to be identified by PCPs as having psychiatric distress when adjusting for all the above nonpsychopathological variables. Patients with depression and comorbid anxiety disorders were more likely to be recognized by the PCP as compared with those with pure depression. Finally, among depressive symptoms, diurnal variation and symptoms related to suicidal tendencies were predictive of identification of psychiatric distress, whereas increase of appetite was negatively associated with PCP recognition.

RESUMEN

Gonadotropin-releasing hormone (GnRH) analogs and antiestrogens display direct antiestrogenic effects on the proliferation of hormone-sensitive breast cancer cells. This study aimed to determine whether growth inhibition of 17 beta-estradiol-stimulated MCF-7 breast cancer cells by the agonist D-Trp6 GnRH, the GnRH antagonist BIM 21009C and 4-hydroxy-tamoxifen (OHT) respectively occurred through alterations of the estrogen receptor (ER)-mediated intracellular pathway. The pS2 mRNA expression is primarily dependent on activated ER in MCF-7 cells, and pS2 protein could act as a growth factor. Drug effect on pS2 mRNAs were qualitatively compared to those on the cell cycle. Unlike OHT, GnRH analogs did not suppress the 17 beta-estradiol-induced pS2 mRNA expression whilst the cell cycle was blocked. The pS2 mRNA expression was induced by D-Trp6 GnRH alone without effect on the cell cycle. The outcome of our study is double. Firstly, GnRH analogs are distinct from OHT as regards their effects on the ER-mediated intracellular pathway. Secondly, pS2 mRNA expression is not strictly related to MCF-7 cell proliferation, suggesting that pS2 protein has a function other than that of critical growth regulator.

RESUMEN

In a large double-blind study of antiemetic therapy conducted in Italy, 289 patients underwent 3 consecutive cycles of cisplatin chemotherapy. Antiemetic treatment with ondansetron plus dexamethasone was more efficacious and better tolerated, but also more expensive, than treatment with metoclopramide plus both dexamethasone and diphenhydramine. To evaluate the different costs of the 2 antiemetic regimens, we conducted a retrospective cost-effectiveness analysis from a hospital perspective. Direct costs of antiemetic therapy (acquisition cost of drugs, materials and time spent by nurses to prepare and administer therapies), cleanup after emesis, rescue medication and adverse events were evaluated. Antiemetic drug acquisition costs per patient were 5.23-fold higher for the ondansetron regimen than for the metoclopramide regimen. However, when the costs of materials and nursing time required to prepare and administer the antiemetic regimens were included, this ratio was 3.77. Furthermore, including the cost of emesis, rescue antiemetic treatments and medication used to treat adverse events, hospital costs per patient were 3.21-fold higher with the ondansetron regimen during the first cycle, 3.08-fold higher during second cycle and 2.89-fold higher during third cycle of chemotherapy. Complete protection from vomiting and from both vomiting and nausea with ondansetron occurred, respectively, in 78.7 and 69.1% of patients in the first cycle, 73.8 and 57.3% in the second cycle, and 74.2 and 58.1% in third cycle of chemotherapy. Corresponding figures for the metoclopramide regimen were 59.5 and 50.4%, 53.6 and 37.1%, and 46.8 and 27.3%, respectively. Thus, the cost per successfully treated (completely protected) patient was 2.43- and 2.34-fold higher, respectively, for ondansetron at the first cycle, 2.23- and 1.99-fold higher, respectively, at second cycle, and 1.82- and 1.36-fold higher, respectively, at third cycle. In conclusion, the study demonstrates that, while ondansetron has a greater acquisition cost than metoclopramide, the ondansetron regimen costs per successfully-treated patient substantially decrease when all direct hospital costs are taken into account.

RESUMEN

Naltrexone significantly attenuated self-injurious behavior in a 20-year-old mildly retarded autistic male patient. The patient was videotaped daily and behavior was evaluated with a time-sampling procedure. Behavioral ratings of SIB frequency, SIB severity, and activity were collected automatically with a computerized system. Learning and memory were tested on a weekly basis with a modification of a paired associate learning test (PALT). Treatment with naltrexone resulted in (a) attenuation of SIB in the unstructured setting and (b) improvements in learning and memory without influencing activity levels.

RESUMEN

According to the laws presently in force in Italy and the guidelines of the Driving Licence Enforcement Commission of Verona, applicants for the driving licence with a history of drug abuse undergo a medical examination, during which complete anamnestic and clinical data are recorded. On this occasion, a hair sample (50-200 mg) is collected and a urinalysis program is started consisting of EMIT controls for opiates, methadone, cocaine, barbiturates, amphetamines, cannabinoids, benzodiazepines and alcohol carried out on eight seriate samples, collected at random over about 40 days under direct supervision. The positive results from urine immunoassays are confirmed by standardized GC/MS methods. The hair samples are screened for morphine and cocaine, the most abused illicit substances in our region, using commercial RIAs adopting cut-off levels of 0.1 ng/mg. All positive samples and about 10% of negative are confirmed by HPLC. In case of confirmed positive results, the applicant is informed: if the subject denies use of opiates or cocaine in the recent months, he or she has the chance of submitting for analysis a new hair sample, which is analyzed in parallel with the hair remaining from the previous assay. In case of persisting denial, claiming analytical interferences by other drugs or endogenous substances, further confirmation of results can be carried out by CE and/or by qualitative MS/MS. In addition, hair sampling from multiple sites (scalp, axillary, pubic hair) with different susceptibility to contamination from the external sources can be carried out to rule out the possibility of passive contamination. At present, we investigate more than 700 subjects per year. The results of this integrated diagnostic strategy are presented and discussed.
