Proprietary sleep aids and sedatives can cause delirium, coma and occasionally death in children and adults. The constituents in sleep aids that significantly effect central nervous system activity are bromides, methapyrilene, pyrilamine and scopolamine (hyoscine). Constituent proportions and mixtures vary greatly at different times since manufacturers make frequent adjustments. The effects of toxicity resulting from the misuse of ethylenediamines include nausea, vomiting, blurred vision, incoordination, tremors, dry mouth, constipation and an acute poisoning syndrome. Management of adverse reactions produced by either methapyrilene or pyrilamine consists of dosage reduction or discontinuation. The acute poisoning syndrome requires implementation of general symptomatic and supportive principles.

A 21-year-old man developed blurred vision and retinal pigment epithelium changes similar to those in acute posterior multifocal placoid pigment epitheliopathy following vaccination for swine flu. The patient's medical examination revealed no infectious agents. A hypersensitivity to the attenuated virus of the swine flu vaccine appears to have produced his initial flu-like symptoms and retinal pigment epithelium changes.

A middle-aged man had blurred vision, redness, and pain in the right eye. Ophthalmoscopic examination revealed slowly progressive necrotizing retinitis in the peripheral superonasal quadrant. The clinical impression was toxoplasmic retinochoroiditis, but lesions failed to respond to steroids, pyrimethamine, and sulfonamides. The eye was enucleated and, histopathologically, showed necrotizing granulomatous retinochoroiditis and optic neuritis, numerous cigarshaped, yeast-like organisms located within the necrotic retina and subretinally, and a subretinal asteroid body. Organisms were identified as Sporotrichum schenkii by immunofluorescence techniques. Electron microscopical studies of the fungus disclosed an unusually thickened capsule with a well-developed cell wall, the outer portion of which exhibited a radiating pattern of granular filamentous material. The ability of S schenkii to cause endophthalmitis in a patient without apparent primary infection should be remembered in the differential diagnosis of a cryptogenic, slowly progressive intraocular infection.

This is the first report of airbag-induced facial and corneal abrasions associated with several weeks of blurred vision in a patient without previous visual or ocular problems. Similar episodes of minor trauma from airbags are becoming commonplace, reflecting the increasing popularity of these lifesaving devices. Nonetheless, airbag-associated injuries, especially facial and ocular injuries, should be monitored and reported to both increase physician awareness and to determine if further airbag design improvements are necessary.

A 42-year-old woman presented with the acute onset of bilateral blurred vision that occurred immediately after bending over. She denied pain or any other associated symptoms. Markedly increased intraocular pressure readings were found. Treatment for acute narrow-angle glaucoma was initiated, and normal vision returned. This case represents an atypical presentation of acute narrow-angle glaucoma, a true ophthalmological emergency. The pathophysiology and treatment options of this disease process are summarized.

A 29-year old female, in her second pregnancy, complained of headache, nausea, vomiting and left blurred vision. In spite of improvement of these symptoms in the second postpartum, she complained of recurrent symptoms in her third pregnancy. CT and MRI showed a pituitary adenoma with hematoma. It was totally removed using the transsphenoidal approach during pregnancy at 8 months. The histological examination revealed that the tumor was an acidophilic adenoma with a hemorrhagic change. A healthy baby was born at the full term after the operation. Our transsphenoidal operation during pregnancy was only the second such attempt reported in our collected literature. The management of the pituitary tumor during pregnancy is discussed.

A 26-year-old woman, gravida 1, para 0, having episodes of confusion, slurred speech, and blurred vision in pregnancy was documented to have severe hypoglycemia with elevated serum insulin and C-peptide levels. Emergency treatment for hypoglycemia was necessary several times during pregnancy. A healthy female infant was delivered after oxytocin induction of labor. Post partum the patient had numerous episodes of severe hypoglycemia in spite of constant intravenous glucose. Computerized tomographic scan of the pancreas failed to show a lesion, whereas pancreatic arteriography revealed a 2 cm mass in the tail of the pancreas. Partial pancreatectomy was performed 6 days after delivery. Microscopic examination of the tissue confirmed the presence of an insulinoma. Hypercalcemia developed together with elevated parathyroid hormone levels. The presence of an insulinoma, hypercalcemia, and a history of hyperparathyroidism in two relatives indicates that this is a case of multiple endocrine adenomatosis type I first diagnosed during pregnancy.

A 68-year-old man developed the sudden onset of transient obscurations of vision in the right eye in November 1988. Two weeks later he noted floaters, photophobia, and blurred vision in the left eye. He presented with unilateral optic disc edema in the right eye. The left eye showed anterior uveitis but a normal optic disc. He was found to be violently seroreactive for Treponema pallidum infection and was also human immunodeficiency virus (HIV) seropositive. Ultrasonography confirmed the presence of a solid thickening of the anterior optic nerve sheath in the right eye. An interesting and dramatic response to penicillin therapy occurred. This is the first instance of a gumma or solid syphiloma of the optic nerve documented by ophthalmic ultrasonography.

We report herein the findings in two patients less than 15 years old with the diagnosis of idiopathic preretinal macular fibrosis, a disorder found primarily in the older population. Only a few reports have discussed idiopathic preretinal macular fibrosis in children and its pathogenesis is still unknown. One is a 10-year-old boy and the other is a 14-year-old girl who visited our hospital with a chief complaint of blurred vision in their right eyes. Epiretinal membranes were recognized on the macular region of their right eyes. Since there was no causative factors, a diagnosis of idiopathic preretinal macular fibrosis was made. They were conservatively followed up. The vision of the boy once worsened but improved spontaneously and remained stable for three years. Because the vision of the girl worsened rapidly, vitreous surgery was performed to remove the epiretinal membrane, resulting in poor vision. It was suggested that this disorder in children should be followed up conservatively and the indication of vitreous surgery should be carefully determined.

Hydroxyzine, a potent H1-receptor antagonist often used for relief of pruritus in patients with hepatic dysfunction, was studied in eight patients, mean age 53.4 +/- SD 11.2 years, with primary biliary cirrhosis. The patients ingested a single dose of hydroxyzine, 0.7 mg/kg (mean dose 43.9 +/- 6.6 mg). Before the dose, then hourly for 6 hours, every 2 hours from 6-12 hours, at 24 hours, and every 24 hours for 6 days, serum hydroxyzine and cetirizine were measured and an intradermal injection of 0.01 mL of a 0.1 mg/mL solution of histamine phosphate was performed. Wheals and flares were traced at 10 minutes and the areas were calculated. Mean peak hydroxyzine levels of 116.5 +/- 60.6 ng/mL occurred at 2.3 +/- 0.7 hours and mean peak cetirizine levels of 500.4 +/- 302.0 ng/mL occurred at 4.8 +/- 2.8 hours. The mean serum elimination half-life of hydroxyzine was 36.6 +/- 13.1 hours, and the mean serum elimination half-life of cetirizine was 25.0 +/- 8.2 hours. The mean hydroxyzine clearance rate was 8.65 +/- 7.46 mL/min/kg, and the mean volume of distribution was 22.7 +/- 13.3 L/kg. The mean wheal area was suppressed (P less than 0.01) from 1 to 120 hours, with maximal suppression from 2 to 48 hours. The mean flare area was suppressed from 1 to 144 hours, with maximal suppression from 3 to 24 hours (P less than 0.01). All patients became sleepy from 0.5 to 6 hours. Blurred vision, dizziness and dry mouth each occurred in two patients. Hydroxyzine elimination is impaired in patients with primary biliary cirrhosis.(ABSTRACT TRUNCATED AT 250 WORDS)
