We examined potential clinical and pathologic correlates of seizures among the 3,291 children in the Childhood Brain Tumor Consortium database. Fourteen percent had seizures prior to their hospitalization for a brain tumor. Among children who had a supratentorial tumor, seizures occurred in 22% of those less than 14 years of age. The prevalence of seizures increased to 68% of older teenagers. Among children with an infratentorial tumor, the prevalence of seizures was relatively constant at 6% over all age groups. The onset of seizures began more than one year prior to surgical tumor removal in over half of the children aged five or more with supratentorial tumors, significantly longer than for those of the same age with infratentorial tumors. Almost all children (98.9%) with an infratentorial tumor and seizures had at least one other symptom and more than three-fourths of them had at least three. Eighty-nine percent of children with a supratentorial tumor and seizures had at least one other symptom and more than one-half had at least three symptoms. Regardless of whether the tumor was above or below the tentorium, confusion or stupor and coma were more common in children with seizures than in children without seizures. Among children with supratentorial tumors, symptoms of a declining academic performance or an abnormality of personality, speech, walking, or sensation were significantly more frequent in children with seizures, while visual symptoms (other than visual loss or diplopia) and nausea or vomiting were less frequent. Among children with supratentorial tumors, those who had seizures were more likely to have paralysis of an arm, hand, or face, confusion or stupor, or coma and less likely to exhibit irritability, papilledema, optic atrophy, decreased visual acuity, pupillary abnormalities, or abducens paresis. Among children with infratentorial tumors, those with seizures were significantly less likely to have truncal ataxia, but more likely to experience confusion, stupor, or coma. In the supratentorial compartment, astrocytoma (nos), protoplasmic astrocytoma, anaplastic astrocytoma, and ependymoma were more frequently associated with seizures than was craniopharyngioma. No infratentorial tumor type was more or less likely to be associated with seizures. All common tumor types that were represented in both the supratentorial and the infratentorial compartment except astrocytoma (nos) were associated with significantly greater rates of seizures when located in the supratentorial compartment. The tumor location with the highest incidence of seizures was, as expected, the superficial cerebrum. More than 40% of the children with such tumors had seizures.(ABSTRACT TRUNCATED AT 400 WORDS)

In this report we present aspects of the epidemiology of headache (i.e., pain in the head, face, ear, or neck) among children with brain tumors. The data are derived from the 3,291 subjects in the Childhood Brain Tumor Consortium databank. Overall, 62% of the children with brain tumors experienced chronic or frequent headaches prior to their first hospitalization: 58% of children with supratentorial tumors and 70% of children with infratentorial tumors. The relative frequency of headache increased through age 7 and then leveled off regardless of tumor location. For children under age 5, headache rarely had a duration of more than 1 year prior to hospitalization. Among children over age 4, headache duration of at least one year was significantly greater for supratentorial than for infratentorial tumors. Children with a brain tumor and headache had a different distribution of symptoms and neurologic signs than those without headache. Tumor location and headache status were interactively associated with the presence of other symptoms and neurologic signs. Children with headache had a greater number of other symptoms and neurologic signs. Regardless of tumor location among children with headache, nausea or vomiting, papilledema, and hypoactive tendon reflexes were more frequent, while upper extremity weakness, optic atrophy, and irritability were less frequent. Diplopia, coma, stiff neck, anesthesia or hypesthesia, pupillary abnormalities, and abnormalities of personality, academic performance, or speech were associated with headache in children with supratentorial tumors. No specific symptoms or neurologic signs were associated with headache in children with infratentorial tumors. Supratentorial craniopharyngioma, ependymoma, and protoplasmic astrocytoma were associated with significantly high rates of headache as was infratentorial pilocytic astrocytoma.

A 19-year old woman who developed rapid nausea, vomiting, tachypnea, and alkalosis within 90 min of taking 3.25 g quinine S04 to induce abortion, was found to have an elevated anion gap and other electrolyte abnormalities. She was normovolemic, and had benign findings on drug screen except for quinine. Her abnormal laboratory values were high serum anion gap of 20 (normal 8-14), high urine anion gap of 171, low HC03- of 29 mEq/L, high Pa)@ of 130 mm Hg, alkalotic pH of 7.5, and hypokalemia of 2.6 mEq/L. Her hypokalemia was judged due to diuresis and vomiting. She was successfully treated with intravenous fluids and supportive care and was discharged on the third day. Quinine intoxication can also cause cinchonism, which is marked by tinnitus, vertigo, blurred vision and scotomata, and possible optic atrophy or death. The toxic dose is 2 g, and the lethal dose 8 g.

Eighty patients with benign intracranial hypertension (BIH) (76 females, 4 males, age range 15-54 years) were studied. Endocrine changes (pregnancy-17, obesity-16, dysmenorrhea-15, hyperthyroidism-7, etc.) were the most common cause of BIH (72.5%-58 from 80). Besides general sings of intracranial hypertension (papilledema-80, headache-76, nausea-47, dizziness-43, obnubilations-39), 36 (45%) patients had visual problems. After treatment complete recovery took place in 48 patients, non-significant residual changes persisted in 16 patients, main symptoms of BIH persisted in 16 patients. Papilledema regressed completely in 52 patients, post-papilledematous discoloration of optic disks or optic atrophy were discovered in 12 patients.

A young woman of 26 years attended eye OPD with the complaints of complete and rapid loss of vision of her righ eye and progressive dimness of vision of left eye, frontal headache and nausea for last two months. On eye examination, she was found to have no perception of light to her right eye. Ophthalmoscopy examination revealed primary optic atrophy in right eye and marked papilloedema to her left eye. CT scan of brain showed space occupying lesion in right parasellar region with sellar and suprasellar extension with involvement of right anterior clinoid process suggesting medial sphenoid wing meningioma. The patient underwent surgery and the histopathology proved the diagnosis as meningioma. The case of medial sphenoid wing meningioma in a young female producing rapid Foster Kennedy syndrome is reported for its unusual presentation.
