Hernia discal traumática. Implicaciones médico-legales.

Traumatic origin of disc herniation, remains as a relevant Medico-Legal problem. The present paper makes a disc protrusion/ herniation revision, mainly about mechanic and traumatic factors involved in their origin. A multifactorial (genetic, bio-antropometric, environnement, metabolic, etc.) causation is concluded to explain etiology of disc herniation. Pure disc herniation (occurring in a healthy non degenerated disc) is considered an exceptional phenomenon. Clinical and radiological spine degeneration sings are revised, along with others that can point to a traumatic origin. Dealing with a disc herniation after an accident, Medical Expert has always to consider the possibility of a precedent disc damage status, assessing the role of a worsening of such antecedent condition in each case. A classification of degree of causation accident-herniation, and antecedent disc damage decompensation are proposed.

Guía para el desarrollo de Programas de intercambio de Jeringuillas (PIJ) desde la consulta de triage de los Dispositivos de Cuidados Críticos y Urgencias (DCCU)

There are exceptional situations where emergency services are required Primary Care in the application of material used by drug-dependent patients, being the response to this demand is something that many of the cases, to individual discretion and the randomness and variability every situation leads to an answer. It calls for a response commensurate to public services and preventive health philosophy in most cases will be carried out by the nurse to perform assistance Devices Critical Care (DCCU), often this first contact these patients and slots at the supply of resources diminishes the possibilities of acquisition of such material to them. That is why, and in the absence in this area of patient safety and professional, a workflow model and according to the prevailing philosophy of working in primary care in terms of prevention policies and recruitment of patients concerned, this project raises guidance for the development of a needle exchange program from the triage consultations DCCU.

Surgical excision with left atrial reconstruction of a primary functioning retrocardiac paraganglioma.

About 2% of all paragangliomas are located in the chest, and a few have been described to be found in the heart. Primary cardiac paragangliomas are extremely uncommon tumors and surgical experience with this neoplasm is limited. Treatment strategies described in the literature have included simple excision, excision with reconstruction, autotransplantation after excision of the tumor and even orthotopic cardiac transplantation, depending on the extent of disease. A primary retrocardiac paraganglioma catecholamine-productive was identified in an asymptomatic 49-year old female associated to familial pheochromocytoma-paraganglioma syndrome caused by germline mutation of the gen which codifies for the subunit B of succinate dehydrogenase enzyme (SDHB). The neoplasm was surgically excised from the posterior surface of the left atrium via median sternotomy using cardiopulmonary bypass. Direct ligation of feeding vessels of the tumor along with left atrial reinforcement using a pericardial patch was performed. The post-operative course was uneventful, with normalization of catecholamine secretion and no recurrence at three-month follow-up. We review the current literature about this exceptional cardiac tumor, pathophysiological conditions and options for surgical management.

Thyroid metastasis as initial presentation of clear cell renal carcinoma.

INTRODUCTION Metastatic tumors account for 1.4-2.5% of thyroid malignancies. About 25-30% of patients with clear cell renal carcinoma (CCRC) have distant metastasis at the time of diagnosis, being the thyroid gland a rare localization [5%]. PRESENTATION OF THE CASE A 62-year woman who underwent a cervical ultrasonography and a PAAF biopsy reporting atypical follicular proliferation with a few intranuclear vacuoles "suggestive" of thyroid papillary cancer in the context of a multinodular goiter was reported. A total thyroidectomy was performed and the histology of a clear cell renal carcinoma (CCRC) was described in four nodules of the thyroid gland. A CT scan was performed and a renal giant right tumor was found. The patient underwent an eventful radical right nephrectomy and the diagnosis of CCRC was confirmed. DISCUSSION Thyroid metastasis (TM) from CCRC are usually apparent in a metachronic context during the follow-up of a treated primary (even many years after) but may sometimes be present at the same time than the primary renal tumor. Our case is exceptional because the TM was the first evidence of the CCRC, which was subsequently diagnosed and treated. CONCLUSION The possibility of finding of an incidental metastatic tumor in the thyroid gland from a previous unknown and non-diganosed primary (as CCRC in our case was) is rare and account only for less than 1% of malignancies. Nonetheless, the thyroid gland is a frequent site of metastasis and the presence of "de novo" thyroid nodules in oncologic patients must be always considered and studied.
