"Is this a dagger I see before me?"--an audit of stabbings and gunshot wounds in Limerick.

BACKGROUND: According to a recent study in Cardiff, the incidence of stab wounds is 14 per 100,000 population per annum. No such figures are available for Ireland. AIM: To evaluate the incidence, type of injury, medical consequences and outcome of patients with stab or gunshot wounds presenting to the Mid-Western Regional Hospital, Limerick, over a 12 month period. METHOD: A retrospective case study of all stab and gunshot wounds presenting over a 12 month period. RESULTS: Out of 62,000 new presentations to the Accident and Emergency (A&E) department, 101 (0.16%) were stabbings, giving an incidence of 33 per 100,000 population. Twenty-six patients required surgical intervention. There were three deaths. There were 10 gunshot wounds, of which 40% required surgical intervention, with no mortalities. CONCLUSION: The incidence of stab wounds presenting to our institution is high. Although constituting a small percentage of presentations to the A&E department they result in considerable morbidity and surgical activity.

Congenital retinoblastoma: a case report.

Retinoblastoma is usually diagnosed during the first three years of life, with an average age of diagnosis of 18 months. It is almost never found at birth except when there is a positive family history which prompts an early fundus examination. We report a case of unilateral nonfamilial retinoblastoma which was so advanced at birth that it had already produced a perforated globe. Despite enucleation, radiation, and chemotherapy, massive orbital recurrence developed which necessitated a modified orbital exenteration. In spite of this aggressive therapy the child died of metastatic retinoblastoma at age eight months.

Stickler's syndrome in the Cleft Palate Clinic.

Stickler's syndrome is a much underdiagnosed entity in the ophthalmic population. It is a dominantly inherited disease of connective tissue whose ocular findings include moderate to severe myopia, vitreoretinal degeneration, retinal detachments, cataracts, and glaucoma. Non-ophthalmologic findings include cleft palate, midfacial hypoplasia, radiographic changes of spondyloepiphyseal dysplasia, narrow pelvis, and broad femoral neck. Twenty percent of patients with Stickler's syndrome will have a cleft palate. We undertook a study to determine the incidence of Stickler's syndrome in patients with an isolated cleft palate, and to see if this screening process would be useful in making an early diagnosis of the syndrome and in genetic counseling. It is important to distinguish this syndrome from that of isolated cleft palate in order to: 1) insure early detection of myopia and monitor for signs of retinal detachment, cataract, and glaucoma; and 2) provide definitive recurrence counseling for families (50% vs 2.3%).

Normative values for visual fields in 4- to 12-year-old children using kinetic perimetry.

We report normative data for 4- to 12-year-old children using a kinetic perimetry technique that employs a double arc perimeter with a 6-degree target designed for use with infants and children. The subject population consisted of 84 children in four age groups (4, 5, 7, and 10 yrs) and 21 adults as comparison subjects. Individuals had eye examinations to rule out causes of abnormal visual fields. Mean visual field size was determined separately for the right and left eyes in each age group. In the 4-year-old group, the mean extent of visual field along each of the four meridians for the right eye was 59, 48, 52, and 85 degrees of arc for radial meridians orientation set at 45, 135, 225, and 315 meridians, respectively. The visual field extent in each quadrant generally increased with age. The overall extent of field as measured along the four meridians for all subject groups increased significantly with the age, indicating a continued growth of visual field size in older children. These data suggest that adult visual field size is achieved at about 11.6 years of age.
