The Clinical Significance of Pollen and Fungi Concentrations for Allergic Rhinitis: A Three-Year Study.

INTRODUCTION: The relationship between disease severity and exposure to allergens in allergic rhinitis (AR) patients is not fully clarified presently. We aimed to detect the correlation between airborne pollen and fungi concentrations in a Mediterranean region with symptom scores. METHODS: A total of 98 patients suffering from AR rated their symptoms at the time of exacerbation using the Total 5 Symptoms Score (T5SS) and the Visual Analogue Scale (VAS). Patients' quality of life (QoL) was estimated by using either disease-specific (Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and mini-RQLQ) or generic (Short-Form 36 (SF-36) and Beck Depression Inventory (BDI)) questionnaires. All patients' responses were correlated with aerobiological data. Skin prick tests (SPTs) were used to detect sensitivities to the most common registered pollen and fungi species. RESULTS: A significant positive correlation between total pollen and fungi counts and disease-specific questionnaires was found only for the RQLQ. Accordingly, a significant positive correlation was found between total pollen and fungi counts and T5SS (r = 0.655, p = 0.021), with breathing (r = 0.620, p = 0.032) and sneezing (r = 0.660, p = 0.020) being strongly affected. Moreover, a tendency toward a higher VAS score was found as total pollen and fungi counts increased (r = 0.523, p = 0.081). CONCLUSION: We found a significant correlation between patients' symptoms and pollen and fungal air concentrations. Our results emphasize the clinical significance of pollen and fungi maps in everyday clinical practice.

Viral-induced inflammation can lead to adverse pregnancy outcomes.

INTRODUCTION: Parvoviruses are DNA viruses of small size. There have been a number of reports indicating the possible effects of B19 infections during pregnancy. These effects include spontaneous abortions, stillbirth, fetal damage, and quite often, fetal anemia with hydrops fetalis.

CYLD expression in endometrial carcinoma and correlation with clinicohistopathological parameters.

OBJECTIVE: Endometrial cancer is a threat to women health worldwide. Cylindromatosis (CYLD) enzyme is a tumour suppressor, considered an effective prognostic marker in various malignancies, but its role in endometrial carcinoma is not fully elucidated. Here, we sought to estimate the prognostic value of CYLD expression in endometrial carcinoma. MATERIALS AND METHODS: CYLD levels were immunohistochemically evaluated in 65 patients with endometrial carcinoma and inferential statistics were applied. RESULTS: Low or negative CYLD expression significantly correlates with older ages, non-endometrioid and invasive carcinomas, tumours with moderate or poor differentiation and advanced stages. Moreover, non-endometrioid and invasive carcinomas are independent risk factors for weaker CYLD expression. Kaplan-Meier analysis illustrated that negative or low CYLD expression is statistically significantly associated with increased death risk, compared to moderate or high expression. CONCLUSION: This study demonstrates for the first time a clear correlation between CYLD expression and clinicohistopathological parameters of endometrial carcinoma patients, suggesting its use as a potential prognostic/predictive marker for Endometrial Carcinoma.

Three-year pollen and fungi calendar in a Mediterranean region of the Northeast Greece.

INTRODUCTION AND OBJECTIVES: Pollen calendars have been proved clinically important in allergic disease management, as differences in airborne allergens exist not only between different countries but also between regions of the same country as well. This study aims to provide new data regarding the atmospheric pollen and fungi content of a Mediterranean region (Western Thrace/North-East Greece) and discuss seasonal trends, differences in pollen grains and fungi spores' circulation over the years, and correlations with climate parameters. MATERIAL AND METHODS: A 7-day continuously running volumetric trap was used to collect circulating pollen grains and fungi spores. Pollen taxa and fungi were characterized by standard protocols and counted as grains /m3 and average total grains and spores. The primary allergenic pollen season was discovered, and their 10-day averages were measured over time. Correlations with temperature, rain, and humidity were assessed by single linear regression analysis. RESULTS: Pollen grains from nine pollen families were identified, including five arboreal, two nonarboreal taxa, and spores from two fungi species. The three most prevalent taxa were Oleaceae, Poaceae, Pinaceae, and Cladosporium in the fungi. Peak pollen concentrations were detected during April and May, with daily averages exceeding 170 grains/m3. Poaceae presented the longest pollen season of 342 days and Oleaceae the shortest, extending to only 110 days, during the 3years. Cladosporium was the fungus with the highest spore concentration (180,129.9 spores) compared with Alternaria (28,026.1 spores). Correlations with meteorological parameters showed variable associations among different taxa, with rainfall and relative humidity being the most significant determinants. CONCLUSION: In this study, the pollenic and fungal spectrum of a Mediterranean region and information that can be proved clinically significant for the appropriate diagnostic and therapeutic approach of allergic patients was presented.

Differential apoptotic activity in trophoblast of spontaneous abortions and normal pregnancies.

INTRODUCTION: Apoptosis is a key process during normal trophoblastic development and, consequently, the whole gestation. However, in trophoblastic differentiation in spontaneous abortions apoptosis has been hardly investigated. Therefore, the aim of the study was to investigate the correlation between apoptotic frequency in trophoblast and spontaneous abortion incidences. MATERIAL AND METHODS: A total of 72 trophoblastic tissue samples were immunohistochemically examined. 42 of 72 derived from first-trimester spontaneous abortions and the remaining 30 from elective terminations during the same trimester of pregnancy. TUNEL assay and M30 marker were used for apoptosis evaluation by immunohistochemistry. RESULTS: Comparative study of tissues from spontaneous abortions and elective pregnancy terminations demonstrated increased expression of both apoptotic markers in tissues derived from spontaneous abortions compared to normal pregnancies. In addition, statistical analysis correlated maternal age and gravidity with increased spontaneous abortion incidences. Moreover, both M30 and TUNEL staining were significantly correlated with maternal age and primigravidity in spontaneous abortion cases. CONCLUSIONS: Our data proved that elevated apoptotic activity during the first pregnancy trimester is clearly involved in spontaneous abortions. Moreover, two well-established apoptotic markers revealed high statistical significance in the evaluation of post-abortive tissues.
