Abstract
OBJECTIVE AND IMPORTANCE To our knowledge, this is the first reported case of the use of stereotactic radiotherapy for an eosinophilic granuloma (EG) of the clivus. We report follow-up information on two previously reported cases and suggest a management plan for this rare lesion. CLINICAL PRESENTATION We report the case of a 4.5-year-old boy who presented with a complete abducens palsy on the right with an associated head turn. A computed tomographic scan of his head revealed a lytic lesion on that side, and magnetic resonance imaging showed the mass to be of low intensity on T1-weighted images and of high intensity on T2-weighted images with heterogeneous enhancement. INTERVENTION A transnasal stereotactic biopsy was performed, revealing an EG. The patient was treated with stereotactic radiotherapy, and he became symptom-free with radiographic resolution of his lesion. Reviewing the literature, we found 13 series with 87 cases of EG in the petrous portion of the temporal bone. EG in the cranial base occurring outside of the temporal bone or in the temporal bone and extending intracranially is, however, quite rare, with only nine other cases reported, two of them clival. CONCLUSION These findings suggest a classification schema in which cranial base EG lesions be grouped with either the more common extracranial petrous temporal bone lesions or the very rare intracranial lesions. Although there are few cases in the literature, treatment results indicate that clival EG, and perhaps all intracranial cranial base EGs, be treated by a biopsy alone, followed by surgery or stereotactic radiotherapy if there is an incomplete resolution of the symptoms or if there is a recurrence.

Abstract
Evidence has emerged that oxygen free radicals contribute to middle-ear mucosa damage in acute otitis media (AOM). Streptococcus pneumoniae is the most common pathogen in AOM and produces hydrogen peroxide, a free radical intermediate, as it grows. To better characterize the mechanism of free radical damage in AOM, an experiment was conducted to examine the production of hydrogen peroxide. Thirty-two guinea pigs were injected transtympanically with bacteria in the left (infected) middle ear and sterile saline into the right (control) middle ear. Middle-ear fluid was removed and analyzed for quantity of hydrogen peroxide. Results indicated significantly greater hydrogen peroxide levels in infected versus control middle-ear fluid at 6, 12, and 24 h. Likely sources of hydrogen peroxide include both the neutrophil response to infection and pneumococcal growth and death.

Abstract
Increasing evidence implicates free radicals in the pathogenesis of inflammatory disease, including otitis media. The anti-oxidant enzymes catalase, glutathione peroxidase and superoxide dismutase protect tissues from the destructive effects of free radicals. Our previous work has shown depressed levels of superoxide dismutase in the infected middle ears of a guinea pig model of otitis media in comparison with normal control ears. We studied the distribution and relative abundance of catalase in the middle ear of this animal model in an effort to elucidate the role free radicals play in the pathogenesis of otitis media. Catalase distribution was mapped immunohistochemically in the middle ears of guinea pigs with induced streptococcus otitis media, and compared with normal control ears. In the control ears, catalase was localized to the epithelium of the middle ear mucosa, with scant distribution in the submucosa. The infected ears demonstrated inflammatory cell invasion with hyperemia and submucosal edema. Catalase was localized to the epithelium and had scant distribution in the submucosa. This distribution was similar to that found previously with superoxide dismutase. Enzyme-linked immunosorbent assay of catalase demonstrated a mean value of 1.00 +/- 0.06 microgram/mg protein in the control ears, and 1.06 +/- 0.12 microgram/mg in the infected ears, but these two values were not statistically different.

Abstract
PURPOSE To analyse the experience with the use of Sideris' device for percutaneous transvenous occlusion of atrial septal defect (ASD). METHODS Thirty six procedures of ASD occlusion were performed in 32 patients; 27 (84.4%) female and five (15.6%) male, mean age of 16 years (4-61). All patients had secundum atrial septal defects with clinical and hemodynamic compromise. The ASD diameter measured < 31 mm and occupied less than 50% of the septal length in all cases. The basic device was used in 28 (87.5%) patients and the self centered model in four (12.5%). The direct implant technique was employed in 15 (41.7%) procedures while in the other 21 (58.3%) an over a wire technique was used. The size of the device was selected according with the Sideris' normogram. RESULTS Occlusion of the defect was achieved in 29 patients (90.63%). In two (6.25%) the position of the device was not adequate and in one (3.12%) the device embolized to the pulmonary artery. In these three cases the device was removed surgically during the defect closure. There was neither morbidity nor mortality in this series. Trivial or small residual shunt was detected with color flow mapping in three (9.4%) patients immediately after the procedure. In 22 patients with 12 months follow-up, trivial residual shunt was present in only one (4.5%). Structural modification of the device was detected in one patient, however with complete ASD occlusion and neither clinical nor hemodynamic disturbance. CONCLUSION The Sideris' device is safe and efficient for ASD occlusion in selected patients. Although there is a relatively high incidence of residual shunt immediately after the procedure, the shunt itself tends to become smaller or disappear during the follow-up and it does not preclude clinical and hemodynamic improvement.

Abstract
OBJECTIVE To examine and compare health status and disease activity changes in patients with rheumatoid arthritis (RA) in a clinical trial of the biologic agent DAB486IL-2. METHODS Data on 45 patients with RA who were enrolled in a multicourse, double-blind trial, consisting of a first, placebo-controlled, course followed by open-label treatment with the active agent to a total of 3 active courses, were examined for evidence of improvement in health status (measured using the 5 components of the Arthritis Impact Measurement Scales 2 [AIMS2]) and disease activity (measured using standard clinical measures and erythrocyte sedimentation rate). RESULTS Over a single course of treatment, DAB486IL-2-treated patients showed significant improvement relative to placebo-treated patients on the symptom and social components of AIMS2 and in patient's assessment of disease activity. With subsequent open-label courses of treatment with DAB486IL-2, all 5 AIMS2 health status components and the disease activity measures of tender and swollen joint counts, grip strength, and the observer and patient assessments showed steady and generally parallel improvement. CONCLUSION Short-term health status effects of this biologic agent were detected using the AIMS2.

Abstract
The objectives of the study were to assess the ability of a fetal pulse oximeter to measure the fetal oxygen saturation (SPO2) continuously during labor and to assess the correlation between readings of fetal pulse oximetry and cord blood gases at birth. The Nellcor N-400 Fetal Oximeter was used in 62 women prospectively. The mean SPO2 was unchanged at the different stages of normal labor. 53.3 +/- 9.1 to 50.1 +/- 11.8% (n = 50). The SPO2 recorded during the pushing phase of stage II (n = 40) was correlated significantly with umbilical cord arterial pH (r = 0.55; p = 0.0002), venous pH (r = 0.63; p = 0.0001), venous PCO2 (r = 0.47; p = 0.002) and venous PO2 (r = 0.39; p = 0.01). SPO2 was also correlated with scalp pH (r = 0.52; p < 0.05; n = 21). No side effects were noted. Fetal pulse oximetry could be useful to assess fetal oxygenation during labor and at birth.

Abstract
Heat shock proteins (hsps) are essential for the survival of cells under an environmental insult. To elucidate the relationship between these intracellular proteins and acute otitis media (AOM), the authors studied hsp production in guinea pigs with AOM induced by inoculation of Streptococcus pneumoniae into the middle ear. Animals were sacrificed 1, 3, or 5 days after inoculation. Immunocytochemical study showed localization of hsp70 within the epithelium of infected ears, while the normal control epithelium showed very light staining. Western blot tests of the mucosal extraction confirmed the presence of hsp70 in otitis media. Enzyme-linked immunosorbent assay (ELISA) showed that hsp levels were higher in the infected mucosa than in the normal control mucosa. In contrast, hsp60 was not stimulated in infected ears. This study showed that hsp70, and not hsp60, was produced in the AOM model.

Abstract
A retrospective chart review was undertaken at Columbia Presbyterian Medical Center to assess the incidence, etiology and management of head and neck infections in pediatric cardiac transplant patients on immunosuppression. From June 1984 to February 1992, 59 cardiac transplants were performed on 57 pediatric patients. Standard immunosuppressive therapy was used. Thirteen of these patients died within three months of transplant and were not included. Of the 44 patient charts reviewed, 82 head and neck infections were documented in 27 patients (61%). There were 26 episodes of sinusitis, 27 episodes of otitis media and 20 episodes of tonsillitis/pharyngitis. Unusual middle-ear pathogens seen included Morganella morgagni and Pseudomonas aeruginosa. These preliminary data suggest that children on immunosuppression for cardiac transplant may be at risk for head and neck infections from unusual or unsuspected organisms, and tympanocentesis plays an important role in diagnosis and treatment. A prospective study is planned to gain further data.

Abstract
Cu, Zn superoxide dismutase (SOD) is a metalloprotein that catalyzes the dismutation of the superoxide anion into O2- and H2O2, and therefore functions to maintain a low intracellular concentration of an otherwise toxic metabolite of oxygen. SOD protects living tissue from the destructive effects of free radicals. Increasing evidence implicates free radicals, including the superoxide radical (O2-), in the pathogenesis of disease, including otitis media. In an effort to elucidate the role free radicals play in the pathogenesis of otitis media, SOD was localized immunocytochemically to determine its cellular distribution in specimens of guinea pig middle ear. In normal ears, SOD was found concentrated in the epithelium of the middle ear mucosa. Low quantities were characteristic of connective tissue, bone, and cartilage. In streptococcus-infected ears, SOD localized similarly, concentrating in the epithelium. The infected ears had extensive submucosal edema which stained poorly and appeared to have less SOD than did normal ears. This was confirmed by an assay using laser densitometry of Western blots to quantify the amount of SOD in the mucosa of normal versus infected middle ears. This demonstrated a value of SOD in normal mucosa of 1.77 +/- 0.48 micrograms/mg of protein compared with 1.02 +/- 0.28 micrograms/mg in the infected mucosa. The two groups were significantly different at P < 0.05. These findings are discussed, and suggestions for future experimentation addressed.

Abstract
Free radicals have been implicated in the pathogenesis of an increasing number of diseases and inflammatory states. They may cause tissue damage by their chemical modification of proteins, carbohydrates, nucleotides, and lipids. Lipid peroxidation occurs as a consequence of free radicals acting on the polyunsaturated fatty acids of cellular membranes. To determine if free radicals play a role in the pathogenesis of otitis media, lipid peroxides and their by-products were assayed in the mucosa of a guinea pig model of otitis media. Both lipid hydroperoxide (LPO) and malondialdehyde (MDA) were measured in the tissues of the middle ear mucosa. Comparisons were made between an infected and a control group. Both LPO and MDA were found to be significantly elevated (P < .01 and P < .05, respectively) in the infected mucosa. Correlation of the biochemical data was made with histologic studies. The significance of these findings as well as suggestions for future experimentation are addressed.

Abstract
Penetration of cefprozil into the middle ear fluid was investigated in patients with chronic otitis media. A total of 89 patients ranging from 7 months to 11 years old participated in the study. The middle ear fluid was removed by ventilation tubes inserted through the tympanic membrane at times ranging from 0.38 to 5.97 h after oral administration of a single dose of 15 or 20 mg/kg of body weight. A blood sample was also collected as soon as the middle ear fluid was removed. Plasma samples were analyzed for the concentration of cefprozil by a high-performance liquid chromatographic assay. Middle ear fluid samples were analyzed for the concentration of cefprozil by a microbiological assay. The concentrations of cefprozil in plasma ranged from 0.38 to 15.97 micrograms/ml at the 15-mg/kg dose level and from 1.28 to 21.47 micrograms/ml at the 20-mg/kg dose level. The corresponding middle ear fluid concentrations of cefprozil ranged from 0.06 to 4.44 micrograms/ml and from 0.17 to 8.67 micrograms/ml, respectively. Cefprozil penetrates well into middle ear fluid in patients with chronic otitis media.

Abstract
Nasal continuous positive airway pressure (CPAP) is being used more frequently in neonatal intensive care units to avoid endotracheal intubation and its attendant complications. Nasal deformities secondary to the nares-occluding prongs employed to deliver the CPAP in former preterm infants have been recognized, and prevention and surgical treatment of these deformities are discussed. An awareness of the potential for these deformities is important to all pediatric otolaryngologists as nasal CPAP is gaining increasing favor as a primary treatment for respiratory disease of the newborn.

Abstract
This study was designed to examine beta-nerve growth factor (NGF) levels in human cord blood by a two-site enzyme immunoassay using MAb 27/21 to mouse NGF and to determine whether beta-NGF levels show developmental changes. Blood was collected at delivery from 61 newborns, 55 neonates appropriate for gestational age (46 term infants and 9 premature infants), 5 neonates small for gestational age, and 1 neonate with congenital hydrocephalus. In addition, samples were collected from 2 microcephalic children (microcephaly vera) aged 15 and 18 mo, 2 control children, and 4 healthy adults. Mean levels of NGF in preterm infants (n = 9; 13.7 +/- 8 pg/mL) were significantly lower than levels in term infants (n = 47; 21.2 +/- 8.8 pg/mL; p = 0.034 by Mann-Whitney U test). There was no correlation between birth weight, length, head circumference, and beta-NGF levels. In microcephalic children, NGF levels were low (8 pg/mL) compared with control infants' values (22 pg/mL). In adults, beta-NGF levels were higher and ranged between 238 and 292 pg/mL. Our study demonstrates that beta-NGF levels can be assessed in human newborn sera using a two-site enzyme immunoassay with MAb 27/21 to mouse beta-NGF, that beta-NGF levels are extremely low in newborns compared with adults, that beta-NGF levels seems to show developmental changes, and that beta-NGF levels may be used to assess NGF utilization under normal and pathologic conditions such as cerebral malformations.
