Hemangioendothelioma of frontal bone.

Radiographic studies disclosed that a 5-year-old girl with proptosis and inferior displacement of her left globe had a lytic lesion in the superior orbital rim. Tissue removed at the time of the initial biopsy was not sufficiently distinctive for a definitive diagnosis, but microscopic examination of residual tumor clearly established the diagnosis of hemangioendothelioma of the frontal bone. Electron microscopic studies demonstrated that the vascular structures, which resembled endothelium, contained many thin microfilaments and mitochondria and scattered dense bodies. Each vessel was surrounded by a prominent mantle of pericytes.

Preschool visual acuity screening tests.

The purpose of the study was to evaluate the relative merits of two screening tests used for visual acuity assessment of preschool children. The tests that were compared were the Good-Lite Company versions of the E-Test and of the STYCAR (Screening Test for Young Children and Retardates). The former is the most popular method for evaluating central acuity in young children in this nation; the STYCAR is a relatively new letter-matching-test developed in England, where it is widely employed. The E-Test poses left-right orientation problems which are eliminated by the symmetrical letters H, T, O and V utilized in the Letter-Matching-Test. Both visual acuity tests were administered on two separate occasions by personnel from the Prevention of Blindness Society of Metropolitan Washington to 633 preschool children in Washington, D.C. By random selection, 150 of the children received the E-Test at both sessions, 162 children received the Letter-Matching-Test at both sessions, 160 chilt athe the second session, and 161 children received the Letter-Matching-Test at the first session and the E-Test at the second session. The author medically examined the eyes of 408 of the 633 children without knowledge of which test had been initially administered. Statistical analysis of the data obtained from the study indicated that the Letter-Matching-Test was significantly better in terms of testability rates, group and individual instruction time, and performance time. The E-Test was more reliable in terms of test-retest acuity scores and was also more valid in terms of agreement between pass-fail results obtained at the first screening session and two levels of pass-fail refraction criteria.

Orbital involvement in 'sinus' histiocytosis. A report of four cases.

Sinus histiocytosis is a newly recognized benign disease affecting mainly children and young adults and usually having a protracted clinical course that is relatively unaffected by therapy. This paper describes four additional patients who had orbital involvement initially and reviews the salient clinical and histopathologic features of this entity. The outstanding clinical feature is cervical lymphadenopathy. Associated findings include low-grade fever, anemia, leukocytosis, and elevated IgG levels. A small percentage of patients develop proptosis with palpable orbital tumors. Such patients may not have appreciable lymphadenopathy. Progressive proptosis may lead to exposure keratitis, corneal ulceration, endophthalmitis, and loss of the eye. Histopathologically, the lymph nodes and orbital mass show a proliferation of large histiocytes intermixed with a variable proportion of lymphocytes and plasma cells. Lymphocytes and occasionally other cells derived from the hematopoietic system are commonly seen within the cytoplasm of the histiocytes.

Cerebro-hepato-renal syndrome of Zellweger. Ocular histopathologic findings.

An infant who was the product of a full-term pregnancy was born with multiple congenital defects, including diffuse bilateral corneal opacification. He failed to thrive and died at the age of 4 days. Autopsy findings were consistent with those seen in the cerebro-hepato-renal syndrome. Histopathologic examination of both eyes, obtained at autopsy, demonstrated similar changes. The main pathologic findings in the anterior segment were bilateral, diffuse corneal edema associated with paracentral iridocorneal adhesions and focal attenuation of Descemet membrane. Both retinas disclosed a selective degeneration of the outer nuclear layers and photoreceptors, confined mainly to the macular region. Atrophy of the optic disc and nerve, with reactive gliosis and demyelination, were consistent with findings in the central nervous system described in this syndrome.

Antiemetic effectiveness of intraoperatively administered droperidol in pediatric strabismus outpatient surgery--preliminary report of a controlled study.

Low doses (0.05 mg/kg) of intravenously administered droperidol were given intraoperatively to randomly assigned pediatric strabismus patients in a controlled double-masked paradigm. No difference between control and treatment groups in the severity of vomiting was noted in the postanesthesia recovery room, but such a difference was probably present in the hospital rooms during the interval between room arrival and the meeting of hospital discharge criteria. Administration of the drug did not appear to produce somnolence sufficient to delay postoperative recovery.

Phlyctenular keratoconjunctivitis.

There is growing evidence that a variety of corneal disorders may be expressions of altered immune mechanisms. Phlyctenular keratoconjunctivitis is probably such a condition. Typically described as arising from hypersensitivity to tuberculin protein, other antigens clearly may participate, particularly staphylococcus products. When corneal involvement occurs, it need not be confined to the peripheral cornea. The symptoms of the process may be disproportionate to obvious findings and so exaggerated as to suggest a psychiatric disorder. Resultant visual deficits, if the disease is corneal, progressive, unrecognized, and untreated may be profound. Representative examples of this disease are cited. Immune mechanisms are reviewed. The importance of recognizing the characteristic sign and symptom complex is stressed. Appropriate diagnostic studies and treatment regimens are presented.

Wegener's granulomatosis presenting as orbital pseudotumor in children.

The case of a nine-year-old white female who presented initially with idiopathic inflammatory pseudotumor and was ultimately diagnosed (22 months later) as having Wegener's granulomatosis is presented. A review of the literature reveals that, to date, there are 21 well-documented cases of Wegener's granulomatosis occurring in children under the age of 16. Of these 21 cases, eight patients (39%) manifested ocular or orbital signs during the course of the disease. Four of these cases (50%) presented initially with idiopathic inflammatory pseudotumor. The diagnosis of Wegener's granulomatosis should be considered in children with orbital pseudotumor. Long-term follow-up may be necessary to exclude this possibility.
