Freezing is a well-known problem in Parkinson''s disease (PD) and is characterized by an abrupt difficulty in starting or continuing rhythmic and repetitive movements. We utilized a questionnaire in order to assess the occurrence of the freezing gait phenomenon (FG) in a population of 100 consecutive PD patients. Our PD population included 70 males and 30 females, with a mean age of 61.1 ± 9.1 years. Mean duration of PD was 6.5 ± 4.0 years. 92/100 patients were under L-Dopa treatment. The FG phenomenon occurred in 60% of patients. It appeared on average 4.8 years after the beginning of PD; in 16% of the cases it was evident before starting L-Dopa treatment. FG was more frequent among female patients. There was no significant correlation between the occurrence of FG and the age of the patients; on the other hand, a significant correlation was found with the duration of the disease (p < 0.001). FG occurred more frequently in the subgroup of patients with the akinetic form (odds ratio: 3.05); whilst an opposite tendency was evident in the subgroup with the tremor predominant form (odds ratio: 0.29).

ABSTRACT

We conducted a retrospective survey in pediatric centers belonging to the Italian Society for Pediatric Diabetology and Endocrinology. The following data were collected for all new-onset diabetes patients aged 0–18 years: DKA (pH < 7.30), severe DKA (pH < 7.1), DKA in preschool children, DKA treatment according to ISPAD protocol, type of rehydrating solution used, bicarbonates use, and amount of insulin infused. Records (n = 2453) of children with newly diagnosed diabetes were collected from 68/77 centers (87%), 39 of which are tertiary referral centers, the majority of whom (n = 1536, 89.4%) were diagnosed in the tertiary referral centers. DKA was observed in 38.5% and severe DKA in 10.3%. Considering preschool children, DKA was observed in 72%, and severe DKA in 16.7%. Cerebral edema following DKA treatment was observed in 5 (0.5%). DKA treatment according to ISPAD guidelines was adopted in 68% of the centers. In the first 2 hours, rehydration was started with normal saline in all centers, but with different amount. Bicarbonate was quite never been used. Insulin was infused starting from third hour at the rate of 0.05–0.1 U/kg/h in 72% of centers. Despite prevention campaign, DKA is still observed in Italian children at onset, with significant variability in DKA treatment, underlying the need to share guidelines among centers.

1. Explain the molecular mechanism of action of vascular disrupting agents. Evaluate the preclinical results of vascular disrupting agents.3. Assess the preliminary clinical results of vascular disrupting agents in the treatment of patients with NSCLC.This article is available for continuing medical education credit at CME.TheOncologist.com. The aim of this review is to discuss the hypothesized molecular mechanisms of action of VDAs and their early preclinical and clinical results, emphasizing ASA404, combretastatin A-4 disodium phosphate, ABT-751, and NPI-2358, reported in the treatment of non-small cell lung cancer, which is the leading cause of cancer death worldwide, and also to discuss future developments in this cancer population.

Lung cancer is the leading cause of cancer mortality worldwide. Non-small cell lung cancer (NSCLC), accounting for about 85% of all lung cancers, includes squamous carcinoma, adenocarcinoma and undifferentiated large cell carcinoma. The majority of patients have advanced disease at diagnosis, and medical treatment is the cornerstone of management. Several randomized trials comparing third-generation platinum-based doublets concluded that all such combinations are comparable in their clinical efficacy, failing to document a difference based on histology. However, recent evidences, arising from the availability of pemetrexed, have shown that histology represents an important variable in the decision making. The major progresses in the understanding cancer biology and mechanism of oncogenesis have allowed the development of several potential molecular targets for cancer treatment such as vascular growth factor and its receptors and epidermal growth factor receptor. Targeted drugs seem to be safer or more effective in a specific histology subtype. All of these data have led to choose the optimal first-line treatment of advanced NSCLC based on histologic diagnosis. However, this scenario raises a diagnostic issue: a specific diagnosis of NSCLC histologic subtype is mandatory. This review will discuss these new evidences in the first-line treatment of advanced NSCLC and their implication in the current clinical decision-making.

Breast cancer arises in about 48% of patients older than 65 years and more than 30% occurs in those over 70 years being the leading cause of cancer-related death in women older than 65. Elderly patients tolerate chemotherapy poorly compared to their younger counterpart because of progressive reduction of organ function and comorbidities related to age. For this reason, the elderly have been excluded from or underrepresented in most cancer studies and, in clinical practice, they often receive inadequate and untested treatments. For adjuvant chemotherapy, a low percentage of patients over 70 years of age were included in few trials and always in a proportion much lower than the prevalence of cancer in that age group. Adjuvant chemotherapy, preferably including an anthracycline especially in patients with HER-2/neu-positive tumours, seems to be beneficial in older women who have substantial risk of dying of breast cancer. To date even if there is no specifically randomised study, single-agent chemotherapy probably might be considered a reasonable treatment for advanced breast cancer in the elderly. One of the actual main field of clinical research in the treatment of breast cancer is the role of targeted therapies. Chronologic age is a risk factor for toxicities such as myelosuppression and mucositis, and older patients may require more supportive care. In order to plan medical treatment in breast cancer elderly patients is mandatory to practice a comprehensive geriatric assessment that includes evaluation of comorbidities, functional dependence, socio-economic, emotional and cognitive conditions, an estimate of life expectancy and recognition of frailty. The authors review the literature regarding age-specific chemotherapeutic issues in the management of breast cancer elderly patients.
