Excited delirium deaths in custody: past and present.

First identified in institutionalized psychiatric populations, chronic excited delirium syndrome was not uncommon in the first half of the 20th century. After a temporal pause, excited delirium re-emerged in the 1980s, in an acute form. Generally occurring in victims without organic mental disease, acute excited delirium is associated with stimulant abuse.

Evaluation of aortic injury in driver fatalities occurring in motor vehicle accidents in the State of Maryland for 2003 and 2004.

Incorporating epidemiological and pathologic factors, a retrospective analysis of aortic injury and driving fatalities was conducted. To better understand the mechanism of injury, data were compiled for decedent demographics, autopsy and toxicology findings, and accident circumstances, with emphasis on directional impact. Review of the autopsy files of the Office of the Chief Medical Examiner in the State of Maryland in 2003 and 2004, identified 150 cases of aortic injury recorded in 537 autopsied drivers.

Death in custody: a historical analysis.

This research delineates the historical evolution of death in custody. A retrospective, exploratory analysis of 145,425 cases from Maryland's Office of the Chief Medical Examiner, occurring from 1939 to 2004, was conducted. Two hundred and two custodial deaths were identified and subsequently examined relative to time, agency, decedent characteristics, and cause and manner of death.

The Brain Tumor Cooperative Group NIH Trial 87-01: a randomized comparison of surgery, external radiotherapy, and carmustine versus surgery, interstitial radiotherapy boost, external radiation therapy, and carmustine.

Objective: The objective of the Brain Tumor Cooperative Group NIH Trial 87-01 trial was to investigate the effect of additional implanted radiation therapy in newly diagnosed patients with pathologically confirmed malignant gliomas.

Methods: The study involved a randomized comparison of surgery, external beam radiotherapy, and carmustine (BCNU) versus surgery, external beam therapy, interstitial radiotherapy boost, and BCNU in newly diagnosed malignant gliomas. (125)I was chosen as best suited for this effort because it allowed preimplantation planning and postimplantation quality assurance review.

Effects of map orientation during learning on airport identification.

Background: If an observer first learns to recognize an object in a specific orientation, a significant increase in processing time usually occurs when the object is subsequently seen in a different orientation; this phenomenon is called the "misorientation effect." The present study examines how quickly and how accurately human observers discriminate between airport maps that are viewed in orientations other than those in which they were initially learned.

Method: Participants were trained to discriminate between two navigation maps that were seen in only one orientation; they subsequently were tested with maps and aerial photographs of the same airports that were presented in various orientations.

Results of a randomized trial comparing intra-arterial cisplatin and intravenous PCNU for the treatment of primary brain tumors in adults: Brain Tumor Cooperative Group trial 8420A.

Purpose: To test the efficacy of intra-arterial (IA) cisplatin versus intravenous (IV) PCNU for treating primary brain tumors, in a randomized trial (Brain Tumor Cooperative Group [BTCG] Trial 8420A).

Methods: 311 adult patients (ages 19-79 years; median 45) with supratentorial tumors (confirmed histologically) were randomized by nine participating institutions. Patients were required to have completed radiotherapy (4500-6020 cGy to the tumor bed) before randomization.

A randomized comparison of intra-arterial versus intravenous BCNU, with or without intravenous 5-fluorouracil, for newly diagnosed patients with malignant glioma.

This Phase III trial tested the efficacy and safety of intra-arterial 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) for the treatment of newly resected malignant glioma, comparing intra-arterial BCNU and intravenous BCNU (200 mg/sq m every 8 weeks), each regimen without or with intravenous 5-fluorouracil (1 gm/sq m three times daily given 2 weeks after BCNU). All patients also received radiation therapy. A total of 505 patients were randomly assigned within the study.

Multimodal treatment of adult intracranial gliomas.

Recent advances, experimental treatments and future protocols of adult intracranial gliomas are discussed in this article. Adult intracranial gliomas are not benign, and most are incurable with poor prognosis, despite aggressive treatment. Breakthroughs will be found only through well-designed, experimental protocol evaluation on patients with intracranial gliomas.

Percutaneous lumbar discectomy: a new adjunct to open surgery.

Percutaneous automated lumbar discectomy is a new and alternative method to open operations for lumbar disc disease. The procedure and indications for the procedure are explained in this article. The results of the first 24 such procedures performed at the Indiana University Medical Center will be examined and discussed.

Radiation-induced intracranial malignant gliomas.

The authors present seven cases of malignant gliomas that occurred after radiation therapy administered for diseases different from the subsequent glial tumor. Included among these seven are three patients who were treated with interstitial brachytherapy. Previously reported cases of radiation-induced glioma are reviewed and analyzed for common characteristics.

Randomized trial of three chemotherapy regimens and two radiotherapy regimens and two radiotherapy regimens in postoperative treatment of malignant glioma. Brain Tumor Cooperative Group Trial 8001.

Within 3 weeks of definitive surgery, 571 adult patients with histologically confirmed, supratentorial malignant gliomas were randomly assigned to receive one of three chemotherapy regimens: BCNU (1,3-bis(2-chloroethyl)-1-nitrosourea) alone, alternating courses (every 8 weeks) of BCNU and procarbazine, or BCNU plus hydroxyurea alternating with procarbazine plus VM-26 (epipodophyllotoxin). Patients accrued in 1980 and 1981 were to receive 6020 rads of whole-brain radiotherapy concurrent with the first course of chemotherapy. Patients accrued in 1982 and 1983 were randomly assigned to receive either whole-brain irradiation as above, or 4300 rads of whole-brain radiotherapy plus 1720 rads coned down to to the tumor volume.

Results of a randomized trial comparing BCNU plus radiotherapy, streptozotocin plus radiotherapy, BCNU plus hyperfractionated radiotherapy, and BCNU following misonidazole plus radiotherapy in the postoperative treatment of malignant glioma.

In Brain Tumor Cooperative Group Study 77-02, eleven institutions randomized 603 adult patients with supratentorial malignant glioma to one of four treatment groups following surgery: conventional radiotherapy (6000 cGy in 30-35 fractions) + BCNU, conventional radiotherapy + streptozotocin, hyperfractionated (twice daily) radiotherapy (6600 cGy in 60 fractions) + BCNU, and conventional radiotherapy with misonidazole followed by BCNU. Data were analyzed for the total randomized population and for the 557 patients (86% with glioblastoma multiforme) who met protocol eligibility specifications (including confirmed histopathology on central review). Median survival was approximately 10 months following randomization.

Candida albicans shunt infection.

Seven cases of successfully treated Candida albicans cerebrospinal fluid shunt infections are reported. Treatment consisted of shunt removal and intravenous Amphotericin B in all cases and intraventricular Amphotericin B in 4 cases. Serious underlying medical illness, recent antibiotic therapy, indwelling intravascular and/or Foley catheters, coincident candidiasis and low birth weight prematurity are major risk factors for candida shunt infection.

Late anaplastic gliomas in children previously treated for acute lymphoblastic leukemia.

At least 33 cases of late anaplastic gliomas in children previously treated for acute lymphoblastic leukemia have been discussed in the literature including 20 well-documented cases. The frequency of this second malignancy is much greater than expected and may represent a 'new syndrome' with some genetic predisposition. Additionally, CNS prophylaxis which includes both radiation and intrathecal methotrexate appears to work synergistically in increasing the incidence of glial tumors especially multifocal tumors in these patients.

Origin of organisms infecting ventricular shunts.

Results of skin cultures obtained before 413 of 505 operations for cerebrospinal fluid-diverting ventricular shunt placement or revision in a pediatric population from April 1980 to May 1983 are analyzed and compared to results of cultures from 20 subsequent shunt infections. Sensitivities to 11 different antibiotics were determined for each isolate cultured. The total operative infection rate was 20 of 505 (4%).

Differential silver staining in lymphocytes and lymphoblastoid cell cultures.

An analysis of the patterns of silver-stained nucleolar organizer regions (AgNORs), an indication of rDNA transcriptional activity, was carried out in metaphases from peripheral lymphocytes and young lymphoblastoid cell cultures (LCL) transformed by Epstein-Barr virus. Four individuals previously shown to carry a double NOR (dNOR) were studied. The dNOR varied in staining frequency and showed intra-individual variation in appearance in both cell types.

Metrizamide-enhanced computed tomography as an adjunct to metrizamide myelography in the evaluation of lumbar disc herniation and spondylosis.

Eighty patients with operatively proven lumbar disc herniation or lumbar spondylosis were preoperatively evaluated with metrizamide myelography followed by metrizamide-enhanced computed tomography (CT). The x-ray films were reviewed without knowledge of the operative findings, and the patients were subdivided into those with disc extrusions, spondylosis, or recurrent abnormalities. For the group as a whole, CT was correct in 82% and myelography was correct in 77%.

Medulloblastoma. Period of risk reviewed.

Collins postulated that patients with Wilms' tumor surviving for a period equal to their age at diagnosis plus 9 months were no longer at risk for a recurrence. Although this no longer holds for Wilms' tumor, it has been applied to patients with medulloblastoma. Case histories of patients who survived a period of risk designated by Collins' rule and later developed a histologically confirmed recurrent medulloblastoma are discussed.

Multiple fusiform intracranial aneurysms following curative radiation therapy for suprasellar germinoma. Case report.

A 17-year-old girl died from the rupture of a large fusiform aneurysm of the terminal internal carotid artery. Autopsy revealed three other fusiform aneurysms originating from major cerebral arteries clearly within the ports of previously administered telecobalt radiation therapy. Five years prior to her death, a suprasellar germinoma was partially removed and the area was treated by radiation therapy via three ports.

Cerebrospinal fluid ascites complicating ventriculoperitoneal shunting. Report of four cases.

Four cases of cerebrospinal fluid (CSF) ascites secondary to ventriculoperitoneal shunting are described. It is possible to differentiate CSF ascites from a CSF-filled pseudocyst by the characteristic bowel gas pattern on films of the abdomen and by the presence of shifting dullness. Two of the patients had active shunt infections, and had ascitic fluid with a protein level greater than 3 gm% and a white blood cell (WBC) count greater than 1000/cu mm.

Comparisons of carmustine, procarbazine, and high-dose methylprednisolone as additions to surgery and radiotherapy for the treatment of malignant glioma.

Within 3 weeks of definitive surgery, 609 patients with histologically demonstrated, supratentorial malignant glioma were randomized to receive, in addition to 6000 rads of radiotherapy, one of four treatment regimens: carmustine (BCNU), high-dose methylprednisolone, procarbazine, or BCNU plus high-dose methylprednisolone. We analyzed the data for the total randomized population and for the 527 patients (87% with glioblastoma multiforme) in whom the initial protocol specifications were met (the valid study group). Significantly longer survival was experienced by patients receiving procarbazine or BCNU alone compared to those receiving only high-dose methylprednisolone.

Randomized comparisons of radiotherapy and nitrosoureas for the treatment of malignant glioma after surgery.

Within three weeks of definitive surgical intervention, 467 patients with histologically proved malignant glioma were randomized to receive one of four treatment regimens: semustine (MeCCNU), radiotherapy, carmustine (BCNU) plus radiotherapy, or semustine plus radiotherapy. We analyzed the data for the total randomized population and for the 358 patients in whom the initial protocol specifications were met (the valid study group). Observed toxicity included acceptable skin reactions secondary to radiotherapy and reversible leukopenia and thrombocytopenia due to chemotherapy.

Intraspinal tumors in children. A review of 81 cases.

The authors have presented 81 children with intraspinal tumors, all less than 16 years of age. The clinical features indicated that gait disturbance, pain, and sphincter disturbance are the most prominent complaints. Reflex changes, paralysis, and sensory impairment are the most frequent physical findings.
