Our aim was to determine the effect of the initial pattern of fracture and the displacement of fragments on the outcome of proximal humeral fractures treated conservatively. We followed 93 consecutive patients prospectively for one year. Final movement and strength were compared with those of the contralateral side. The final American Shoulder and Elbow Society score and the Disabilities of Arm, Shoulder and Hand and Short-Form 36 questionnaires were compared with those provided by the patient on the day of the injury. Radiographs and CT scans with three-dimensional reconstruction were obtained in all patients. The pattern of the fracture and the displacement of individual fragments were analysed and correlated with the final outcome. There were two cases of nonunion and six of avascular necrosis. The majority of the fractures (84 patients; 90%) followed one of the following four patterns: posteromedial (varus) impaction in 50 patients (54%), lateral (valgus) impaction in 13 (14%), isolated greater tuberosity in 15 (16%), and anteromedial impaction fracture in six (6%). Head orientation, impaction of the surgical neck and displacement of the tuberosity correlated strongly with the outcome. In fractures with posteromedial impaction, a poor outcome was noted as the articular surface displaced inferiorly increasing its distance from the acromion. A poorer outcome was noted as a fractured greater tuberosity displaced medially overlapping with the posterior articular surface. Lateral impaction fractures had a worse outcome than other patterns of fracture. ©2011 British Editorial Society of Bone and Joint Surgery.

Obesity Surgery | Year: 2011

Background: Intragastric balloon is a widely used technique to treat obesity that is considered to be more efficient than conservative treatment before bariatric surgery. To describe air-filled balloon (Heliosphere BAG®) effectiveness [absolute weight loss, body mass index (BMI) loss, percentage of body weight loss (BWL), percentage of excess weight loss (EWL)] and complications 6 months after its insertion. Methods: Eighty-four consecutive intragastric balloons were placed endoscopically. Individualized nutritional counseling was given. The follow-up was carried out in an endocrinology outpatient clinic. Due to the weight or height data missed in two cases, only 82 patients were included in this report, 63 women with a mean age 39 years (SD, 11.1); mean BMI, 39.1 kg/m 2 (SD, 5.8). The median follow-up was 182 days. Results: The mean weight loss and BMI loss were 14.5 kg (SD, 8.2); and 5.3 kg/m 2 (SD, 2.8), respectively (for difference, p<0.001). The mean percentage of BWL was 13.4% (SD, 7.0). Of the sample, 70.4% achieved a percentage of BWL >10%. The percentage of EWL reached 33.2% (SD, 19.2). After adjusting by sex and initial BMI, absolute weight loss (p=0.033), BMI loss (p=0.034), percentage of BWL (p=0.034), and percentage of EWL (p=0.034) were inversely related to age. Absolute weight loss and BMI loss were greater in higher initial BMI, but the percentage of EWL was lower. Two spontaneous deflations occurred (3%), but only one surgical early removal (1.2%) was required. Nausea and vomiting developed in 7.4% of the patients during the first week. Conclusions: Air-filled Heliosphere BAG® has been effective in achieving a relevant loss of body weight. © 2011 Springer Science + Business Media, LLC.

Expert Opinion on Biological Therapy | Year: 2012

Introduction: Since the presence of circulating cell-free fetal DNA (ccffDNA) in maternal peripheral blood was demonstrated in 1997, great efforts have been done in order to use this source of fetal material for noninvasive prenatal diagnosis. The advantage that it represents is avoiding the obstetric invasive procedures required for conventional prenatal diagnosis. Areas covered: Efforts are mainly focused on finding the most accurate way to diagnose the most common fetal aneuploidies, paying special attention to trisomy 21. Recent advances in technology offer new diagnostic tools with high degrees of sensitivity thus generating great expectations for this type of diagnosis. However, there are other reasons why pregnant women undergo conventional prenatal diagnosis. Being at risk of transmitting a monogenic disorder is one of them. And although the percentage of those pregnancies may represent a small percentage of the diagnosis performed in the first trimester, these numbers should not be underestimated. Expert opinion: Management of pregnancies at risk of an X-linked Mendelian disorder has changed thanks to the noninvasive fetal sex assessment. As for other Mendelian disorders, until recently, their study was limited to those cases paternally inherited. Nevertheless, the new emerging technologies are also opening the scope to maternally inherited disorders. © 2012 Informa UK, Ltd.

Prenatal diagnosis (PD) is available for pregnancies at risk of monogenic disorders. However, PD requires the use of invasive obstetric techniques for fetal-sample collection and therefore, involves a risk of fetal loss. Circulating fetal DNA in the maternal bloodstream is being used to perform non-invasive prenatal diagnosis (NIPD). NIPD is a challenging discipline because of the biological features of the maternal blood sample. Maternal blood is an unequal mixture of small (and fragmented) amounts of fetal DNA within a wide background of maternal DNA. For this reason, initial NIPD studies have been based on the analysis of specific paternally inherited fetal tracts not present in the maternal genome so as to ensure their fetal origin. Following this strategy, different NIPD studies have been carried out, such as fetal-sex assessment for pregnancies at risk of X-linked disorders, RhD determination, and analysis of single-gene disorders with a paternal origin. The study of the paternal mutation can be used for fetal diagnosis of dominant disorders or to more accurately assess the risk of an affected child in case of recessive diseases. Huntington's disease, cystic fibrosis, or achondroplasia are some examples of diseases studied using NIPD. New technologies are opening NIPD to the analysis of maternally inherited fetal tracts. NIPD of trisomy 21 is the latest study derived from the use of next-generation sequencing (NGS). © 2012 Elsevier B.V.

Wide-neck intracranial aneurysms remain a challenge to endovascular treatment. We describe our experience in repairing wide-neck aneurysms of the anterior circulation located at arterial branch points using coil embolization assisted by Y-stenting using two Solitaire® stents. Six wide-neck intracranial aneurysms located on the middle cerebral artery bifurcation 3, pericallosal artery 1, and anterior communicating artery 2 were repaired by Y-stent-assisted coil embolization using two Solitaire® stents. Four cases were incidental findings of aneurysm and two cases were previously treated ruptured aneurysms that had undergone recanalization. All the cases were successfully treated without complications. Follow-up by digital subtraction angiography and magnetic resonance angiography at six months showed the stents to be patent with no recanalization of the aneurysm sacs. Repairing wide-neck aneurysms of the anterior circulation by Y-stent-assisted coil emboli-zation using two Solitaire® stents is a simple and safe method of treating complex aneurysms. While the results are promising, larger series with longer term follow-ups are needed to corroborate that this treatment method is superior to other techniques.
