Filter by:EVITA is a multicentric Latin-American prospective cohort on chronic hypersensitivity pneumonitis. EVITA's objective is to identify phenotypes and/or endotypes associated with different disease trajectories measured primarily by forced vital capacity (FVC) during a 24 month follow-up period. Other secondary measures of disease progression will also be investigated such as imaging, time to death or lung transplantation, and patient-reported outcomes
This study is being conducted to see effectiveness of auto-inoculation of a wart in multiple viral warts. Patients with recurrent, multiple warts of all types, are being recruited for the study. A wart is excised, minced and then inoculated in a subcutaneous pocket made on the volar aspect of forearm. Patients are to be reviewed after every 4 weeks to note any reduction in number warts.
This is a single arm phase 1b/2 evaluation of the combination of oregovomab, and bevacizumab, paclitaxel carboplatin in adult subjects with CA125-associated, advanced recurrent epithelial ovarian, fallopian tube or peritoneal carcinoma (FIGO Stage III/IV) with BRCA-wild type, previously treated with 1 prior lines of therapy, and with platinum free intervals of >6 months since last platinum-based treatment.
To assess the efficacy of skin tests with platinum salts in patients suspects with immediate hypersensitivity reactions. All patients adressed in consultation to the Allergy Department of university hospital of nancy for an immediate hypersensitivity reaction to platinum salts between 2015 and 2021 were retrospectively recruited.
To evaluate the safety and effectiveness of Sodium Stibogluconate in the treatment of myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) with p53 mutation from a defined list. The list includes 65 p53 mutations that were experimentally confirmed to be pharmacologically restored with tumor-suppressive function by antimonials.
Polycystic ovary syndrome (PCOS) is a common endocrinological disorder seen in 6%-10% of women (Human Reproduction, 2004). It is characterized by polycystic ovaries, anovulatory cycles, and hyperandrogenism. In nearly 20% of infertile women, PCOS is said to be the key reason behind infertility (Norman et al., 2007). PCOS is a syndrome that manifests variably from adolescence as oligomenorrhea or hirsutism or obesity and goes on to affect the reproductive performance of the female by causing anovulation. Some may even be severely affected by metabolic syndrome, diabetes mellitus, or endometrial carcinoma. It also increases the risk of ovarian and breast carcinoma (Atiomo et al., 2003). PCOS falls in WHO type II anovulation (norm-gonadotropic norm-estrogenic anovulation) and is seen in 85% of anovulatory females. Although lifestyle modification is known to improve reproductive outcomes in females with PCOS, the gold standard treatment for norm-gonadotropic oligo/amenorrheic infertility (WHO Group II) was clomiphene citrate (CC) (Radosh L., 2009) until 2018, when ESHRE and ASRM have declared letrozole as the first-line treatment for ovulation induction (OI)( ESHRE 2018 guidelines). To conclude, available data shows that letrozole is at least as effective as CC for ovulation and has comparable live birth rates. Importantly, it has definite advantages over CC. Many studies have shown letrozole to be as effective as gonadotropins, with added advantage of low cost and lower multiple pregnancy rates. However, the quality of medical evidence supporting aromatase inhibitors for OI, are inadequate, small in sample size, and inappropriate design. Moreover, there is very limited data on potential teratogenic effects, oocyte, embryo quality, and any effect on implantation. ( Misso et al., 2012) Those who fail to respond to CC are labeled as clomiphene resistant. It is common in approximately 15%-40% of women with PCOS (NICE, 2014). Major factors postulated for CC resistance include obesity, insulin resistance, (seen in nearly 50%-70% of females with PCOS) and hyperandrogenemia (Parsanezhad et al., 2001).Moreover, genetic predisposition is suggested to play a role in CC resistance (Overbeek et al., 2009).However, still, the current data available on the causes of CC resistance are not sufficient enough to direct our treatment. It is seen in various studies (Sohrevardi et al.,2016) that the females who initially failed to respond to CC develop better ovulation and pregnancy outcomes on treatment with insulin-sensitizing agents. This indicates that insulin resistance may be a cause of CC resistance in females with PCOS. In fact, insulin-sensitizing agents (Azziz et al., 2009) decrease the dose of ovulation-inducing agent and time for follicular maturation in females with PCOS. As of now, there have been no concrete studies to compare the metabolic profile of females who respond to CC and those who do not. It is still an enigma as to why some women respond to clomiphene, while others do not. By identifying the various factors which affect the response of CC in patients with infertility, a lot of time can be saved by giving alternate options of treatment to these patients. This study was done with the aim to analyze various clinical, metabolic, hormonal, and ultrasound parameters that might affect the response to clomiphene.
To evaluate the photo-protector effect of BC_3 (E212657) formulated in SPF compared to SPF alone on long-UVA induced pigmentation in healthy volunteers.
Up to 135 patients with hypersensitivity pneumonitis will be enrolled at 7 clinical centers across the United States. Patients will be followed for 24 months to determine if biomarkers in the blood can predict disease progression.
The purpose of this study is to strengthen our ability to accurately diagnose allergies and understand cellular, humoral, genetic components and physiological changes in allergic disease
Central sensitization (CS) is as increased response to normal or sub-threshold stimuli of central nervous system. Patient history and physical examination, quantitative sensory testing(QST), imaging methods, neuroinflammatory marker levels, electrodiagnostic studies and clinical scales can be used in the diagnosis of CS, but there is no standardized method yet. Among these methods, clinical scales are preferred because they are practical, inexpensive and do not require experience. The Sensory Hypersensitivity Scale was developed by Dixon et al. for investigate the personal hypersensitivity and CS. The aim of this study is to investigate the Turkish validity and reliability of the sensory hypersensitivity scale.
