FOLFOX4 in the treatment of metastatic colorectal cancer in elderly patients: A prospective study

Elderly patients constitute a subpopulation with special characteristics that differ from those of the general population and have been under-represented in clinical trials. We, prospectively, analyzed the toxicity and efficacy of the original FOLFOX4-regimen in the treatment of elderly patients affected by metastatic (m) colorectal cancer (CRC). Thirty-six consecutive patients aged 67-82 years (median age 72 years), 22 males and 14 females, with mCRC and measurable disease, were enrolled in the study. The primary site of metastases was the liver (36.1% of patients). The median ECOG Performance Status (PS) was 1. The main hematological and extra-hematological (grade 3 or 4) toxicities were neutropenia (38.9%) and neurological (13.9%), respectively. A total of 36 patients, aged 67-82 years were included. Twenty-two and 14 patients were male and female, respectively. The median age was 72 years (range 67-82). The primary site of metastases was the liver (36.1% of patients). The median ECOG Performance Status (PS) was 1. The overall response rate (ORR) was 44.4% and similar to original study. Median progression-free survival (PFS) was 7.5 months and median overall survival (OS) was 16 months. The main hematological and extra-hematological (grade 3 or 4) toxicities were neutropenia (38.9%) and neurological (13.9%), respectively. Tolerability, however, was manageable and no toxic death occurred. FOLFOX4-regimen maintains its efficacy, and safety ratio in elderly patients with mCRC and good performance status. It would be considered the treatment of choice in the treatment of this particular setting of patients.     

Ghrelin and reproductive disorders

Ghrelin is an important factor involved in most of the metabolic and hormonal signals which adapt the reproductive functions in conditions of altered energy balance. Moreover, the coordinated role of leptin and ghrelin appears in fact to have a specific role in the regulation of puberty. Systemic action of ghrelin on the reproductive axis involves the control of the hypothalamic-pituitary-gondal axis. In addition, it has been shown that ghrelin may directly act at a gonadal level in both females and males. Available data also demonstrate that sex steroid hormones and gonadotropins may in turn regulate the gonadal effect of ghrelin, as documented by studies performed in females with the polycystic ovary syndrome and in hypogonadal men. Notably, recent studies also confirm a potentially important role for ghrelin in fetal and neonatal energy balance, and specifically in allowing fetal adaptation to an adverse intrauterine environment.     

The European LeukemiaNet: achievements and perspectives

The only way to cure leukemia is by cooperative research. To optimize research, the European LeukemiaNet integrates 105 national leukemia trial groups and networks, 105 interdisciplinary partner groups and about 1,000 leukemia specialists from 175 institutions. They care for tens of thousands of leukemia patients in 33 countries across Europe. Their ultimate goal is to cure leukemia. Since its inception in 2002, the European LeukemiaNet has steadily expanded and has unified leukemia research across Europe. The European LeukemiaNet grew from two major roots: 1) the German Competence Network on Acute and Chronic Leukemias; and 2) the collaboration of European Investigators on Chronic Myeloid Leukemia. The European LeukemiaNet has improved leukemia research and management across Europe. Its concept has led to funding by the European Commission as a network of excellence. Other sources (European Science Foundation; European LeukemiaNet-Foundation) will take over when the support of the European Commission ends.     

Sleep breathing disorders in 40 Italian patients with Myotonic dystrophy type 1

The aim of this study was to estimate the prevalence and nature of sleep breathing disorders in Myotonic dystrophy type 1 (DM1). We wanted to determine whether there is a relationship between sleep breathing disorders and clinical parameters such as pulmonary function, degree of neuromuscular impairment, daytime sleepiness, and fatigue. This will help assess the prevalence of DM1 patients requiring nocturnal ventilatory treatments. We studied a random sample of 40 unrelated patients and found that 22/40 patients had obstructive sleep apnoea. Of these 22 patients, five showed also periodic breathing and four showed sleep hypoventilation. Nine patients were put on nocturnal ventilation following clinical and instrumental evaluations. Our study reveals that obstructive sleep apnoea is very common in these patients, but cannot be predicted on the basis of clinical-neurological features and diurnal functional respiratory tests. Our data emphasize that a periodical evaluation by polysomnography should be mandatory to ascertain, and treat if necessary, the presence of obstructive sleep apnoea, periodic breathing or nocturnal hypoventilation.     

Jaw-opening oromandibular dystonia secondary to Wilson's disease treated with botulinum toxin type A

We have reported a case series of five patients with jaw-opening oromandibular dystonia secondary to Wilson's disease (WD), in which the patients were treated with botulinum toxin type A (BTX-A). In all cases, dystonia score was partially reduced three weeks after injections. The most common side effect was transient mild dysphagia. This preliminary study showed that jaw-opening oromandibular dystonia in WD may be partially responsive to the use of BTX-A.     

Movement disorders emergencies: a review

Movement disorders (MD) encompass acute and chronic diseases characterized by involuntary movements and/or loss of control or efficiency in voluntary movements. In this review, we covered situations in which the main manifestations are MDs that pose significant risks for acute morbidity and mortality. The authors examine literature data on the most relevant MD emergencies, including those related to Parkinson's disease, acute drug reactions (acute dystonia, neuroleptic malignant syndrome, serotonergic syndrome and malignant hyperthermia), acute exacerbation of chronic MD (status dystonicus), hemiballism and stiff-person syndrome, highlighting clinical presentation, demographics, diagnosis and management.     

Comparison of high‐power short‐duration (HPSD) ablation of atrial fibrillation using a contact force‐sensing catheter and conventional technique: Initial results

Introduction: Atrial fibrillation (AFib) ablation is alternative treatment to drugs. Literature suggests that use of contact force (CF) catheter with higher power for short periods is effective and safe. Methods/Results: Retrospectively analyzed 76 patients undergoing the first ablation. Third five patients‐group A: 27 (77%) paroxysmal AFib (PAFib) and 8 (23%) persistent AFib (PersAFib) who underwent ablation at the power of 30 W‐17 mL/minute flow with a CF of 10‐30 g for 30 seconds. Fourty one patients‐group B: 28 (68.3%) PAFib and 13 (31.70%) PersAFib underwent ablation using 45 W on posterior wall with CF of 8/15 g, as well as 50‐W anterior wall with CF of 10/20 g‐35 mL/minute flow for 6 seconds. Pulmonary vein isolation in both groups and ablated. For patients not in the sinus, we performed cardioversion before ablation. No complications. Group A: Left atrial time 110 ± 29 minutes, total 148 ± 33.6 minutes, radiofrequency time (RF) 4558 ± 1998 seconds, X‐ray 8.5 ± 3.5 minutes, and elevation of esophageal temperature (ET) in 26 (74.3%). group B: Left atrial time 70.7 ± 18.5 minutes ( P < .00001), total 106 ± 23 minutes ( P < .00001), RF 1909 ± 675.8 seconds ( P < .00001), X‐ray 8.8 ± 6.6 minutes ( P = .221) and elevation of ET in 21 (51.20% ‐ P = .0578). In 6 and 12 months follow‐up, we had 9 (25.71%) and 11 (31.42%) recurrences in group A and 5 (12.19%) and 7 (17.07%) in group B ( P = .231 at 6 and P = .14 at 12 months), respectively. Conclusions: HPSD was safe, useful, and efficient compared with CT, and reduced procedural time and total RF time. HPSD may reduce esophageal injury because of lower heating rate and it may reduce the recurrence of atrial tachyarrythmias.     

The use of a portable gamma camera for preoperative lymphatic mapping: a comparison with a conventional gamma camera

Purpose  

Planar lymphoscintigraphy is routinely used for preoperative sentinel node visualization, but large gamma cameras are not always available. We evaluated the reproducibility of lymphatic mapping with a smaller and portable gamma camera.
