Approximately 10% to 20% of patients who undergo selective transsphenoidal removal of secreting microadenomas fail to achieve a cure. One of the possible causes of these failures is multiple adenomas. A case history is presented of two microadenomas within the same gland, and the multiplicity of pituitary adenomas is discussed.
The authors present a case of delayed myelopathy arising 8 years after a stab wound to the thoracic spine, with intradural retention of the knife tip. Following removal of the knife tip, the patient had a good recovery. A review of the literature documents eight additional cases of delayed myelopathy secondary to retained fragments from spinal stab wounds.
AbstrAct Adverse drug events impose a large cost on the society in terms of lives and health care costs. In this article, we propose an information technology architecture for enabling the monitoring of adverse drug events in an outpatient setting as a part of the post marketing surveillance program. The proposed system architecture enables the development… (More)
The authors describe the use of metrizamide spinal computed tomography scan to delineate the surgical extent of spinal subdural empyema in a 65-year-old diabetic female.
To properly diagnose and treat the Chiari I malformation, it is necessary to know: 1) the position of the cerebellar tonsils; 2) the degree of compression of the upper cervical cord and medulla; 3) the status of the spinal cord, particularly whether a syringohydromyelic condition exists; 4) whether basal arachnoiditis is present; 5) the nature of the… (More)
Due to its capability of producing a well localized intense heat field of predictable dimensions, the electromagnetic field focusing probe was evaluated experimentally as a surgical tool in aneurysm thrombosis. Aneurysm models were created by anastomosing a segment of vein to the abdominal aorta. Seventy-five such aneurysms were created in seventy-five… (More)
A technique for scalp marking using computed tomography (CT) images is described. A reference marker is placed on the scalp and a plain lateral skull film is obtained. Using the CT scan image and the CT scout film, the target is marked on the plain skull film. The distance and angle of the target from the reference point on the plain film are measured and… (More)
The latissimus dorsi-gluteal myofasciocutaneous flap has been successfully employed in closure of 6 large thoracolumbar myelomeningoceles in newborn infants. Good wound healing was attained in all cases. The technique of flap mobilization and closure is outlined and possible pitfalls are explained.
Fifty-six in vitro microcytotoxicity assays were conducted on 30 patients with intracranial tumors at various times during the postoperative course. Significant specific cellular cytotoxic responses were found in nine of 56 assays, humoral cytotoxic responses in nine of 54 assays, and host effector cell-dependent, antibody-dependent cytotoxic responses in… (More)
