Coexistence of vertebral osteomyelitis and lesions of the aorta is rare but may be lethal if not diagnosed promptly and treated effectively. We describe a patient who was treated at the Cleveland Clinic Hospital, and we review 69 additional cases reported in the literature. The native aorta was involved in 66 cases; four patients developed infection of prosthetic aortic grafts. The most common aortic lesions associated with vertebral osteomyelitis were mycotic aneurysms, infected aneurysms, and pseudoaneurysms. The wide variety of pathogens involved included salmonellae and other gram-negative bacilli, mycobacteria, gram-positive cocci, and fungi. In some cases infection was polymicrobial. The condition was associated with protean clinical manifestations. Diagnosis was frequently delayed, and mortality was 71%. In some instances surgical procedures at sites of unsuspected aneurysms precipitated life-threatening hemorrhage. Therapy with antimicrobial drugs alone was insufficient. The best results were achieved when specific drug therapy was combined with resection of the infected aorta or aortic graft, thorough debridement, and extraanatomic bypass grafting.
We report the case of a 44-year-old woman with complex partial seizures (CPS) of right frontotemporal origin who developed generalized amnesia after undergoing intracranial electrode implantation complicated by left hippocampal hemorrhage. Serial memory testing disclosed recovery from the amnesic disorder, while repeated magnetic resonance imaging (MRI) showed resolution of her left hippocampal hemorrhage in a 2-month period. A second intracarotid amytal procedure confirmed the capability of her left temporal region to support memory. Consequently, a right orbitofrontotemporal lobectomy was performed without complication.
Outcome as a function of employment status or return to school was evaluated in severely head-injured patients. A priori we selected the most salient demographic, physiological, neuropsychological and psychosocial outcome predictors with the aim of identifying which of there variables captured at baseline or 6 months would best predict employability at 6 or 12 months. Based on the patients evaluated at 6 months, 18% of former workers had returned to gainful employment and 62% of former students had returned to school. For those not back to work or school at 6 months, 31% of the former workers and 66% of the former students had returned by 12 months. Age, length of coma, speed for both attending and motor movements, spatial integration, and intact vocabulary were all significantly related to returning to work or school. The three most potent predictors for returning to work or school were intactness of the patient's verbal intellectual power, speed of information processing and age.
Carney's complex is characterized by cardiac and cutaneous myxomas, mammary myxoid fibroadenomas, spotty mucocutaneous pigmentation, primary pigmented adrenocortical disease, large-cell calcifying Sertoli cell tumors of the testis, growth hormone-secreting pituitary adenomas, and psammomatous melanotic schwannomas. We present an illustrative case of Carney's complex in a 26-year-old woman who at age 20 underwent bilateral adrenalectomy for Cushing's syndrome. Six years later, she suffered multiple central nervous system embolic episodes secondary to three cardiac myxomas, which led to her death. Appropriate evaluation and management of patients with Carney's complex is outlined.
Squamous cell carcinoma of the bladder has been associated with exstrophy, defunctionalized bladders, chronic infection, cystolithiasis, and chronic indwelling catheters. We report a case of squamous cell carcinoma of the bladder in a woman performing intermittent self-catheterization for the previous 14 years.
