Diagnostic problems and postnatal follow-up in congenital toxoplasmosis

2007

Aim. In order to assess the consequences of different clinica] approaches in the prenata] management of congenital toxoplasmosis, we retrospectively reviewed 58 pregnant women with Toxoplasma seroconversion and prospec­ tively enrolled their 59 infants, referred to us from 1999 to 2004. Metbods. Data on clinica!, laboratocy and de­ mographic characteristics of the pregnant women were collected. Their children were entered intoa 48-month follow-up progcamme in which clinica , instrumental, ophthalmo­ logic and serologic evaluations were carried out at birth, at 1, 3, 6, 9, 15, 18, 24, 36 and at 48 months of life. Paediatric treatment with Spiramycin alone or alternated with Pyrime­ thamine-S…

FOCAL ACTIVE COLITIS AS A PREDICTOR OF INFLAMMATORY BOWEL DISEASE: RESULTS FROM A SINGLE-CENTER EXPERIENCE.

2017

The term focal active colitis (FAC) is conventionally used to describe the presence of isolated cryptitis, characterized by an inflammatory infiltrate consisting of intraepithelial neutrophils and/or neutrophils invading the lumen of the criptae, with no other microscopic alteration of the colonic mucosa and, in particular, without the presence of signs of chronic inflammation. To date, only four studies, including one conducted in a pediatric population, have been performed to evaluate the clinical significance of this disease. The aim of this retrospective study on prospectively-collected data is to evaluate the clinical implications of the focal active colitis, since there still remains …

PERSONALITY TRAITS IN PATIENTS WITH NEUROEPITHELIAL TUMORS - A PROSPECTIVE STUDY

2018

Abstract Aim of this study was to analyze personality traits in patients with neuroepithelial brain tumors. Personality alteration is a common feature in brain tumor patients, but not much is known about associations between specific personality changes and brain tumors. We assessed potential factors influencing personality such as tumor location, tumor grade and tumor volume. Mini-mental state examination (MMSE), Beck’s Depression Inventory II (BDI-II), and the NEO Five-Factor Inventory (NEO-FFI) for the five factors of personality were acquired. Patients had lower scores regarding the factor openness and higher scores regarding the BDI-II compared to the norm population. No significant in…

Havep53 gene mutations and protein expression a different biological significance in colorectal cancer?

2002

p53 alterations are considered the most common genetic events in many types of neoplasms, including colorectal carcinoma (CRC). These alterations include mutations of the gene and/or overexpression of the protein. The aim of our study was to assess whether in 160 patients undergoing resective surgery for primary operable CRC there was an association between p53 mutations and protein over-expression and between these and other biological variables, such as cell DNA content (DNA-ploidy) and S-phase fraction (SPF), and the traditional clinicopathological variables. p53 mutations, identified by PCR-SSCP-sequencing analysis, were found in 68/160 patients (43%) and positive staining for p53 prote…

A metabolomic approach to dry eye disorders. The role of oral supplements with antioxidants and omega 3 fatty acids.

2014

Purpose We used nuclear magnetic resonance spectroscopy of hydrogen-1 nuclei (1H NMR S) to analyze the metabolic profile of reflex tears from patients with dry eye disorders. Methods We performed a prospective case-control study involving 90 participants: 55 patients diagnosed with dry eye syndrome (DESG) and 35 healthy subjects (control group, CG). From the DESG, two subgroups were formed: mild DES (n=22) and moderate DES (n=33). Participants were prescribed an oral nutraceutic supplementation containing antioxidants and essential polyunsaturated fatty acids to be taken as three capsules per day for 3 months. Reflex tears (20–30 µl) were collected from the tear meniscus of both eyes of eac…

SARS-CoV-2 antibody persistence after five and twelve months: A cohort study from South-Eastern Norway

2022

Objectives To assess total antibody levels against Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS CoV-2) spike protein up to 12 months after Coronavirus Disease (COVID-19) infection in non-vaccinated individuals and the possible predictors of antibody persistence. Methods This is the first part of a prospective multi-centre cohort study. Participants The study included SARS-CoV-2 real-time polymerase chain reaction (RT-PCR) positive and negative participants in South-Eastern Norway from February to December 2020. Possible predictors of SARS-CoV-2 total antibody persistence was assessed. The SARS-CoV-2 total antibody levels against spike protein were measured three to five months aft…

Does Preoperative Treatment with a Gonadotropin-Releasing Hormone Agonist Improve the Outcome of Endometrial Resection?

1998

Abstract Study Objective. To verify if more favorable long-term results of endometrial resection can be obtained with preoperative gonadotropin-releasing hormone (GnRH) agonist treatment. Design. Multicenter, randomized, controlled trial (Canadian Task Force classification I). Setting. Tertiary care academic department. Patients. Sixty-three premenopausal women with established menorrhagia. Intervention. Eight weeks of goserelin depot treatment before endometrial resection or immediate surgery in the early proliferative phase of the cycle. Measurements and Main Results. Variations in menstrual patterns and bleeding scores as well as overall degree of satisfaction with treatment were determi…

Does the level of serum antimüllerian hormone predict ovulatory function in women with polycystic ovary syndrome with aging?

2012

Abstract OBJECTIVE: To determine possible prediction of regular menses with aging in anovulatory women with polycystic ovary syndrome (PCOS). DESIGN: Cohort. SETTING: Academic practice. PATIENT(S): A total of 54 anovulatory women with PCOS and 28 age- and weight-matched control subjects. INTERVENTION(S): Blood and ovarian ultrasound at baseline and after 5 years. MAJOR OUTCOME MEASURE(S): Serum antimüllerian hormone (AMH), gonadotropins, androgens, insulin sensitivity, and ovarian ultrasound. RESULT(S): After 5 years, there was a significant decrease in AMH in women with PCOS and control subjects (10 of 54 anovulatory women became ovulatory after 5 years). There was a significant negative c…

2017

Since features of polycystic ovary syndrome (PCOS) have been found to be prevalent in women with functional hypothalamic amenorrhea (FHA), we wished to determine what happens to these features after recovery of menstrual function in FHA Design: Prospective cohort study. Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied.Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied. We measured serum estradiol, LH, FSH, testosterone, DHEAS, anti-Mullerian hormone (AMH), body mass index, and ovarian morphology on transvaginal ultrasound.At baseline, 12 of the 28 women (43%) had increased AMH (4.7 ng/mL), and higher testosterone and larger ovaries c…
