Optic radiation involvement in optic pathway gliomas in neurofibromatosis.

Purpose: Optic pathway gliomas (pilocytic astrocytomas) in neurofibromatosis type 1 (NF-1) typically involve some combination of the optic nerves, chiasm, or optic tracts. Involvement of the optic radiations is rare.

Design: This paper describes seven patients with NF-1 with gliomas involving the pregeniculate optic pathway in addition to the optic radiations.

Cutis aplasia of the scalp: three cases in eighteen months.

Three patients with cutis aplasia of the scalp presented to Arkansas Children's Hospital over a period of eighteen months. Two of the patients required operative intervention for closure of the defects and the third patient healed with dressing changes. Surgery required the combined efforts of both neurosurgery and plastic surgery.

Case of the month. Symptomatic chronic calcified subdural hematoma in a 5-year-old child.

Head trauma is a frequent cause of morbidity and mortality in the pediatric population. The pathophysiology and clinical outcomes of head trauma differ between children and adults. Traumatic mass lesions such as subdural and epidural hematomas occur less frequently in children and, when present, are associated with lower mortality.

Benign nonmeningeal tumors of the cavernous sinus.

Objective: Resection of benign cavernous sinus tumors with minimum morbidity and mortality is increasingly more common. Although meningiomas have dominated most discussions, numerous nonmeningeal tumors also deserve attention because they are generally more amenable to radical surgical resection.

Methods: We reviewed the records of 40 patients (19 female and 21 male patients) who were treated surgically during a 15-year period for benign, nonmeningeal tumors of the cavernous sinus.

Blood culture technique based on centrifugation: clinical evaluation.

A total of 1,000 blood samples from patients suspected of having a bacteremia were analyzed concurrently, where possible, by three methods: (i) Trypticase soy broth with sodium polyanethol sulfonate and a CO2 atmosphere: (ii) pour plates with either brain heart infusion agar or Sabouraud dextrose agar; and (iii) centrifugation of the suspected organism in a hypertonic solution. There were 176 positive cultures. The centrifugation technique recovered 73% of the positive cultures.

Blood culture technique based on centrifugation: developmental phase.

A quantitative and flexible blood culture system based on centrifugation of lysed blood over a density layer is described. The effect of relative centrifugal force, centrifugation time, and two different density solutions on the recovery of Staphylococcus aureus, Escherichia coli, pseudomonas aeruginosa, and Candida albicans was determined. To demonstrate the versatility of this technique, the reisolation of 23 representative microorganisms from inoculated normal human blood was determined at a fixed centrifugation speed and time.

New procedures for purification of L-asparaginase with high yield from Escherichia coli.

l-Asparaginase is now known to be a potent antineoplastic agent in animals and has given complete remission in some human leukemias. Extensive clinical trials of this enzyme, however, were not possible in the past because of inadequate production of this substance. We have developed practical procedures for producing l-asparaginase in yields of sufficient quantity and purity for more extensive clinical evaluation.
