Frequency of Factor V Leiden in Juvenile Migraine With Aura

Patients with migraine are known to be at risk for stroke. It has been reported that in a group of patients with cerebral ischemia and the Leiden mutation of factor V, 67% had classical migraine. We have studied the frequency of this mutation in a group of Italian children and adolescents affected by migraine with aura.
The Leiden mutation was detected in 2 (3.5%) of 57 patients and in 8 (3.7%) of 219 controls. The 2 patients carrying the mutation had no peculiar characteristics as compared with the rest of the migrainous population. In our study, the frequency of the Leiden mutation in patients was not different from that of controls. These data contrast with those collected in the Finnish population and in a group of northwestern Italian adult patients, but agree with results previously reported from The Netherlands.     

Deletion 5p11 accompanied by multiple numerical changes in testicular lymphoma.

We describe a case of testicular B cell lymphoma with deletion of chromosome 5, del(5)(p11), as a sole structural abnormality. Histopathological diagnosis of the tumor was a high-grade lymphoma of the diffuse type containing cells positive for B cell specific antigen (CD20) and negative for the leukocyte common antigen (CD45). Deletion 5p may define the region of a tumor suppressor gene that could be associated with tumor progression and invasiveness and may serve as an indicator of poor prognosis in testicular lymphomas.     

Correlation of body mass index and leptin with tumor size and stage of disease in hormone-dependent postmenopausal breast cancer: preliminary results and therapeutic implications

Obesity is considered the most important risk and prognostic factor for estrogen-dependent breast cancer in postmenopausal women. Adipokines, in particular leptin, are at the center of the etiopathogenetic mechanisms by which obesity and related metabolic disorders influence breast cancer risk and its prognosis. The present prospective observational study aims to investigate the relationship between body mass index (BMI), serum levels of leptin and proinflammatory cytokines, and breast cancer prognostic factors. In the study, 98 postmenopausal and 82 premenopausal patients with ER-positive breast cancer participated. During the same study period, 221 control subjects were simultaneously recruited. Women underwent baseline measurements pre-operatively, before any surgical and systemic treatments. Pathologic characteristics of tumors were abstracted from pathology reports. Leptin and proinflammatory cytokines were assayed in stored fasting blood specimens. In postmenopausal breast cancer patients, BMI, leptin, and interleukin-6 significantly correlated with pathological tumor classification (pT) and TNM stage. Multivariate regression analysis showed that BMI and leptin, but not interleukin-6, were independent predictive variables of pT and TNM stage. Our results seem to suggest a twofold role of leptin in the etiopathogenesis of postmenopausal estrogen-positive breast cancer. Indeed, leptin reflects the total amount of fat mass, which correlates to aromatase activity and subsequent estrogens levels. Further studies are warranted to clarify the role of leptin and interleukin-6 in breast carcinogenesis and identify new therapeutic options, beyond the use of aromatase inhibitors, acting selectively on adipokine-driven pathways.     

The carboxyl terminal trimer of procollagen I induces pro-metastatic changes and vascularization in breast cancer cells xenografts

Background  

The COOH terminal peptide of Pro-collagen type I (PICP, also called C3) is chemotactic for endothelial melanoma and breast cancer cells. PICP induces the expression of Metalloproteinases-2 and -9, of Vascular endothelial growth factor and of the chemokine CXCL-12 receptor CXCR4 in MDA MB231 breast carcinoma cells in vitro.     

Three cases of laparoscopic myomectomy performed during pregnancy for pedunculated uterine myomas

Purpose

Laparoscopic myomectomy during pregnancy is indicated when symptoms related to uterine myomas persist despite pharmacologic therapy; however, currently there is very little information concerning its safety.

Methods

We report three cases of antepartum laparoscopic myomectomy performed to manage complicated myomas requiring surgical intervention.

Results

In particular, we report for the first time in literature the laparoscopic removal of two myomas in a patient during a single surgery performed in the 19th week of pregnancy followed by additional multiple myomectomy at the time of the cesarean section. All surgeries were without complication.

Conclusions

Our experience suggests that laparoscopic myomectomy may be performed safely during pregnancy; even more studies are needed to establish the exact rate of adverse events.     

Evaluation of the effectiveness of treatment with erythropoietin on anemia, cognitive functioning and functions studied by comprehensive geriatric assessment in elderly cancer patients with anemia related to cancer chemotherapy

The primary aim of the present study was to examine the relationship of changes in hemoglobin levels following recombinant human erythropoietin (rHuEPO) treatment to changes in cognitive functioning studied by Mini Mental State Examination (MMSE) in elderly cancer patients undergoing chemotherapy treatment. The secondary aim was that to assess the relationship of changes in hemoglobin levels following rHuEPO treatment to changes in functions studied by Comprehensive Geriatic Assessment (CGA), such as Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Geriatric Depression Scale (GDS) and the Mini Nutritional Assessment (MNA). To this end, hemoglobin levels and cognitive functioning were evaluated in a sample of cancer patients prior to the start of chemotherapy treatment and again after 4, 8 and 12 weeks of treatment with chemotherapy plus rHuEPO. Ten elderly patients (mean age 71.4 years) were enrolled. At baseline, enrolled patients had a mean Hb value of 10.3g/dl. After 4 weeks of rHuEPO treatment, Hb values increased significantly (p<0.0001), with a mean increase of 1.2g/dl (range: 0.2-2.1). Remarkably, 8 out of 10 (80%) showed an increase of Hb levels >or=1g/dl in comparison to baseline and therefore were considered responders. At baseline, four patients (40%) showed a moderate cognitive impairment, whilst six patients (60%) showed a normal cognitive function. After 4 weeks of rHuEPO treatment nine patients (90%) showed a significant improvement of cognitive functions in comparison to baseline (p<0.005): eight of them were responders also to rHuEPO in terms of correction of anemia. The Spearman's rank correlation test showed a statistical significant correlation between Hb increase and increase in cognitive functioning assessed by MMSE after 4 weeks (p=0.049), 8 weeks (p=0.044) and 12 weeks (p=0.031) of rHuEPO treatment. Therefore, the findings of this study provide support for the hypothesis that significant increases in hemoglobin over the course of chemotherapy supplemented with rHuEPO administration would be accompanied by significant improvement in cognitive performance over the same interval.
