Generally speaking, slowly progressive, dull neck or evaluation of metastatic spine tumor prognosis that, in- back pain which occurs in a patient with a known cancer stead, allows a correlation of the tumor extent with the disease or which may become apparent in an elderly pa- 123 tient without a history of a tumor, should be considered as tebral body is weakened by the replacement of bone by tu- caused by a spinal metastases until proven otherwise. Usually the posterior period between initial pain and neurological deficit is for elements are also involved to some extent at this point and the cervical and thoracic spine weeks to months but in the render the segment definitely unstable. The patients may metastases are prone to pathological fractures with frag- have motor or sensory deficit or both, whereas there is the ment displacements only if there is a certain mix with os- option of pure radicular and/or a medullary compression. Osteoblastic metastases can reach a Since most tumors start in the vertebral body, an anterior considerable hardness which makes a fracture rather im- cord compression can be expected which is represented probable; however, they can initiate radicular or medullar by a deficit of the corticospinal pathways with the clinical compression due to the solidity of the tumor tissue.

However, as a search methodology reversible if they last more than 48 h or even shorter [12, and for appreciation of the spinal tumor involvement MRI 13, 18, 25]. Sphincter disturbances also present rather is the diagnostic tool of choice.

It cannot be difficulty with a prostate problem and women with the overlooked, however, that MRI may be overinterpreted by bladder/uterus relationship as well as a weak pelvic floor.

Overall survival in this patient cat- lowed by e anterior revision and restabilization after a previous embolization of the tumor and occlusion of one of the vertebral ar- egory is around 12 months [12, 15, 33, 48, 51, 54, 56].

When given to women in labor, opioids may decrease uterine Sulfonamides should not be used during the last trimester contractility and slow progress toward delivery. They cross the placenta and causes less neonatal respiratory depression than other opioids. If respiratory depression occurs, it can be studies indicate embryotoxicity. Trimethoprim, often given in combination with sulfamethoxa- zole (Bactrim), is contraindicated during the first trimester.

Scopolamine may cause respiratory depression in the Antianginal Agents (Nitrates) neonate and may contribute to neonatal hemorrhage by reducing The drugs lower blood pressure and may decrease blood supply to vitamin K–dependent clotting factors in the neonate. Anticoagulants Antianxiety and Sedative-Hypnotic Agents Heparin does not cross the placenta and has not been associated (Benzodiazepines) with congenital defects.

Most of these effects pregnant women causes physical abnormalities in their offspring.

Tricyclic antidepressants (eg, amitriptyline) have been associated Antitubercular Drugs with teratogenicity and embryotoxicity when given in large doses, These drugs are recommended for treatment of active tuberculosis; and there have been reports of congenital malformations and use for prophylaxis can usually be delayed until after delivery. Monoamine oxidase inhibitors niazid, ethambutol, and rifampin were embryocidal or teratogenic (eg, phenelzine), were associated with fewer viable offspring and in animal studies. The effects of drug combinations on the fetus are growth retardation in animal studies with large doses.
