Long-term use of deferiprone significantly enhances left-ventricular ejection function in thalassemia major patients

A multicenter randomized open-label long-term sequential deferiprone–deferoxamine (DFP-DFO) versus DFP alone trial (sequential DFP-DFO) performed in patients with thalassemia major (TM) was retrospectively reanalyzed to assess the variation in the left ventricular ejection fraction (LVEF) [1].     

Side of onset does not influence cognition in newly diagnosed untreated Parkinson's disease patients

BackgroundA relation between the side of motor onset and cognitive impairment in early PD has been reported, suggesting that the asymmetric degeneration affecting subcortical regions may play a pivotal role in lateralized cognitive function. However, evidences are controversial and all previous studies were performed on treated patients, though it is known that dopaminergic therapy can affect cognition in PD.MethodsSixty-nine early untreated PD patients underwent an extensive neuropsychological battery exploring memory, visuospatial and attention/executive functions. Patients were divided with respect of the side of onset (right vs. left) and further grouped according to motor phenotype (tremor vs. rigidity-bradykinesia). Multivariate analysis of variance has been carried out to compare clinical and neuropsychological data between subgroups.ResultsThere were no differences in any neuropsychological task between right-sided and left-sided onset subgroups, irrespective of tremor dominant or rigid-bradykinetic phenotype. Age at onset was significantly higher in patients with any cognitive impairment as compared with patients without (66.7 ± 3.2 vs. 56.3 ± 6.8 years, p = 0.001).ConclusionSide of motor onset is not a major determinant for developing lateralized cognitive deficits in newly diagnosed untreated PD patients.     

Male–female differences in left-handedness in Sardinia,Italy

Males were consistently found to be more likely than females to report left-hand preference in single-hand tasks, but the literature reports negative results too. Using data from a large sample in Sardinia, we aimed at testing the links of left-handedness with sex, age, residence, and seasonality of birth. A total of 4239 participants (males = 1589; females = 2650) were recruited in public places such as high schools, university classes, or gyms in one of the major islands of Italy. Hand preference was established with the question: Which hand do you normally use to write legibly? The monthly distribution of births was studied with the Rayleigh test. In the sample, 270 female participants reported left-hand preference in writing (10.2%) versus 161 male participants (10.1%). Left-hand preference in writing was negatively related to age, with increasing left-hand preference in the younger generations. Left-hand preference in writing was not more common in urban than in suburban or rural settings. The month of birth was found to have a seasonal effect on the left-handed (p=.031) but not on the right-handed (p=.80) participants, and this seasonal effect was more evident in males (p=.04) than in females (p =.26). In our sample males were not more likely to report left-hand preference in writing than females. On the other hand, left-hand preference does vary by age and, in all likelihood, this is an effect of the reduced cultural pressure to write with the right hand in the younger generations.     

Laparoscopic sacropexy and obstructed defecation syndrome: an anatomoclinical study

Introduction and hypothesis

Laparoscopic sacropexy (LSP) is associated with obstructed defecation syndrome (ODS) in 10–50 % of cases. An anatomoclinical study was carried out to investigate whether there is any correlation between iatrogenic denervation during LSP and ODS.

Methods

Five female cadavers were dissected to identify possible sites of nerve injury during LSP. Subsequently, the videos of 18 LSP were blindly reviewed to assess the location of sacral dissection and tacks, the position and depth of the peritoneal tunnel, and another 4 variables. An anatomical triangle was defined on the right lumbosacral spine so as to clearly describe the sites of the surgical variables, which were then statistically correlated with the patients’ postoperative outcome.

Results

The only variable associated with postsurgical ODS was dissection in the 90° angle of the anatomical triangle, where the superior hypogastric plexus was observed in all cadavers.

Conclusions

Medial and midline dissection over the sacral promontory might be associated with postoperative ODS.     

Long-term follow-up of ruptured intracranial aneurysms treated by microsurgical wrapping with autologous muscle

The purpose of this study is to describe our series of nine unclippable and uncoilable ruptured aneurysms in eight patients treated by microsurgical wrapping with autologous muscle. Records were retrospectively reviewed for rebleeding rate, morbidity and mortality, changes in size or the aneurysm’s configurations, and inflammatory reaction. We conducted a Medline search in the post-microsurgical era, excluding patients in whom wrapping was part of the aneurysm treatment in combination with clipping or coiling. The surgically related morbidity was 12.5 %. Global mortality rate was 25 % due to vasospasm (one case) and rebleeding (one case). Six patients are still alive. Rebleeding rate was 14.3 % within 6 months; then, it was zero. Glasgow outcome scale (GOS) score at discharge was 1 and 4 in one patient, respectively, and 5 in the remaining six. Mean clinical follow-up was 126 months. GOS at last follow-up was 4 and 5 in 50 % of patients, respectively. Mean mRS score was 0.8 at 2 months, and 2.4 at 12 months. Follow-up MR demonstrated persistence of the aneurysm’s sac, without changes in size and configuration. Patients did not describe or exhibit symptoms attributable to complications inherent to the use of muscle. Microsurgical muscle-wrapping of ruptured intracranial aneurysm is safe, is associated with a low rate of acute and delayed postoperative complications and rebleeding, and could be a valid alternative for unclippable and non-amenable to endovascular procedure ruptured aneurysms.     

Feasibility and safety study of day-case Transtar™ procedure

BackgroundShort hospitalization surgery is cost effective and convenient for both patients and healthcare system. Stapled transanal rectal resection (STARR) conducted with the new curved device, Contour Transtar, has proved an effective and safe procedure for treatment of obstructed defecation syndrome.The aim of this study was to determine the safety and feasibility of STARR, performed as a day-case procedure.Material and methodsRetrospective review was performed of all STARR performed as day-case surgery between September 2009 and February 2011. The entire study (intervention, data collection and data analysis) was conducted at the One-day Surgery Unit of the St. Andrea Hospital, Rome, Italy. All patients with surgical indication to STARR for the presence of an obstructed defecation syndrome were included in the study. We excluded from day-case protocol, patients over 65 years old, with an ASA score of III–IV or with a BMI over 35. The surgical technique reflects the original technique proposed by Antonio Longo with the exception of the longitudinal prolapse opening, which was created with the use of an electric scalpel between two Kocher clamps and not by an application of Transtar stapler. To evaluate the feasibility and safety of performing this procedure with short hospitalization, we investigated the presence and the time of presentation of post-operative complications.ResultsEighty-nine patients underwent STARR as a day-case regimen, and none presented major complications or required an extension of hospital stay or readmission.ConclusionsSTARR performed with Contour Transtar, in selected patients, is safe and feasible in day-case regimen if performed by expert surgeons and in a structure that allows the physician to keep the patient hospitalized or to re-admit and promptly treat those patients who present major surgical complication.
