Venous thromboembolic disease is a major cause of morbidity and hospital mortality in the world. Although exact figures are unknown in our country, to achieve uniformity of criteria among the specialties involved in the prophylaxis and treatment will have a clearer picture of this entity and contribute to a more rational and interdisciplinary approach, managing to improve the quality of care for patients and raise the level of awareness of this entity. This is a sufficient justification for the effort led by collegiate work of experts and specialists in the field, was given the task of developing a management algorithm for prophylaxis in hospitalized patients at risk of venous thromboembolic disease. This group of experts at a plenary working session, achived uniformity criteria and reached agreement by consensus, so that the bibliography is updated and revised to try to adapt to our current hospital situation.

Neurological endovascular therapy is a discipline that has shown effectiveness and safety in the management of intracranial aneurysms, however recanalization persists as one of the most important obstacles to overcome. Precise knowledge of the anatomy and hemodynamics of the aneurysm and the parent artery as well as currently available endovascular devices, are decisive in the analysis and to design a specific treatment plan for each case. In this manner we ensure, as long as possible, success and durability of the treatment.

Background: An endoscopic endonasal transsphenoidal approach is reported as less invasive, allowing an earlier discharge. Published series have never focused on its use in acromegalic patients. Objective: To assess the effectiveness of an endoscopic endonasal transsphenoidal approach in the management of growth hormone-secreting adenomas. Patients and methods: Nineteen consecutively operated patients were assessed with a prospective follow-up of one year. Results: Sex ratio was 0.7/1 and gross total removal was obtained in 16 cases (84%), subtotal in three (16%). The only complication was a cerebrospinal fluid leak requiring spinal drainage. The median in-hospital stay was 2.5 days. Sixteen patients experienced clinical improvement (84%) and no changes were observed in three (16%). Residual tumor was seen in two cases (11%). Growth hormone levels < 2 ng/dl were seen in 17 cases (89%) and only two patients (11%) had a level > 2 ng/dl. Insulin-like growth factor-1 levels were normalized in 16 cases (84%) and remained elevated in three patients (16%). One patient presented an isolated elevated level of insulin-like growth factor-1. Patients with residual tumor and elevated growth hormone and insulin-like growth factor-1 levels underwent complementary radiosurgery. Conclusions: The endoscopic endonasal transsphenoidal approach seems to be useful in acromegaly, with a high rate of clinical and biochemical cure among other benefits.

Objectives: To identify and evaluate the cerebral aneurysm remnants after clipping and the endovascular treatment in our institution. Methods and materials: We made a clinical ambispective collection of all aneurysms microsurgically clipped during four years and we analyzed their endovascular treatment. Results: There were 290 cerebral aneurysms; in 270 a digital subtraction angiography was made. Ten aneurysm remnants were found (3.7%); of these, a second operation was performed on two, and coil placement was done in six patients. Conclusion: The cerebral aneurysm remnants after clipping in our institution are equivalent to international results. The endovascular treatment of this aneurysm is safe and effective.

In this work, the design and manufacture of a new jaw prosthesis for a young patient with articular Ankylosis is reported. The required models were obtained with a Computed Axial Tomography (CAT) in conjunction with computed aided design (CAD) and engineering codes. Several tomography slices were taken in digital format (DICOM). Each slice was processed with Scan IP, CATIA and Solidworks. The main objective of this study is to show the digital and a physical processing for manufacturing the desired model, taking into account the anthropometry of the young patient, who expects to receive this fixation as a maxillary implant. The STL and FEM model allowed creating biomechanical prototypes in order to adjust the disorders that this young patient has suffered by three incorrect medical procedures. It will allow manufacture the final mold by using of a quick prototyping printer system (dust). This prosthesis will be created as an only piece, and the main body will be created by a strong, low weight and polymeric material Poly(methyl methacrylate)—(PMMA), while a low friction metal will be considered for the condylar joint. The expectation for this final implant requires the approval of the Specialty Hospital “La Raza” (IMSS) in order to be installed on the patient. For this purpose, biomechanical engineering procedure and 3D manufacturing quick prototyping was used for the prototype. The clinical case discussed in this paper is related to a 17-year-old individual. He was treated in the area of maxillofacial and plastic surgery. The severity of the deformation was based on congenital disease. Calcium hydroxyapatite, Poly(methyl Methacrylate) polymers and stainless steel, which are highly biocompatible materials, were used for this purpose. It is very important to mention that this procedure avoided the employment of bone tissue taken from the ribs and cranial regions as in other research publications referred. As a result of this research, a unique 3D personalized jaw model could be presented in order to be fixed in the patient. © Springer International Publishing Switzerland 2015.

In this work, the design and manufacture of a new assembled prosthesis for a jaw for a young Mexican patient with Temporo Mandibular Disorder (TMD) and articular ankilosys is reported. The required models were obtained with a computed axial tomography (CAT) in conjunction with computed aided design (CAD) and engineering codes. Several tomographic slices were taken digital format (DICOM). Each slice was processed with Scan IP, Unigraphics and Solidworks. The main objective of this study is to show the digital and a physical processing for manufacturing the desired model, taking into account the anthropometry of the young patient, who expects to receive this fixation as a maxillary implant. The parametric FEM model allows creating biomechanical testings in order to evaluate its mechanical response before the final manufacturing by using of a quick prototyping printer system (dust). This prosthesis will be created as an assembly, and the condylar joint will be created by a low friction metal. The expectation for this final implant requires the approval of the Hospital ‘‘La Raza’’ (IMSS) in order to be installed on the patient. For this purpose, a biomechanical engineering procedure and 3D manufacturing quick prototyping was used for the prototype.
