Symptomatic ventricular coaptation, or the slit ventricle syndrome, is frequently described and recognized as a clinical entity in the pediatric population. It is characterized by symptoms of shunt failure (i.e., ataxia, obtundation, nausea, vomiting, lethargy, irritability, and complaints of headache) and the CT findings of ventricular coaptation (slit-like ventricles). This study of twenty-two children with this syndrome reflects the variety of possible clinical presentations, and the variety of available treatment modalities. Multiple therapeutic approaches were required in seven of the patients. This illustrates not only an evolving treatment regimen, but also that a single treatment modality is not universally effective. Six patients needed only occasional symptomatic support. Blockage and/or removal of the shunt system was the definitive therapy in six patients, pressure augmentation in nine patients, and subtemporal craniectomy in one. This article outlines the theoretical pathophysiology, and a scheme for the management of patients with this syndrome.

Renal amyloidosis was confirmed in 6 related male and female Beagles, ranging in age from 5 to 11 years. The most commonly reported signs of illness included lethargy, anorexia, vomiting, and weight loss. Common clinicopathologic abnormalities were normocytic, normochromic anemia; hypoalbuminemia; azotemia; hypercholesterolemia; proteinuria; and urine specific gravity values below the normal range. Histologic examination of renal tissue from the 6 Beagles revealed moderate to severe glomerular amyloidosis with inconsistently observed mild medullary interstitial amyloidosis. Congo red-stained kidney sections from 4 of 4 affected dogs were potassium permanganate-sensitive, suggestive of reactive amyloidosis. Hereditary predisposition for renal amyloidosis was suspected in these Beagles.

A five-year-old girl presented with profound growth failure, lethargy, vomiting and acidosis. A diagnosis of Munchausen syndrome by proxy was made after the demonstration of egg albumin, diphenhydramine and phenothiazine metabolites in her urine. Growth improved dramatically, but a subsequent child in the family died of sudden infant death syndrome.

An overdose of up to 850 levothyroxine sodium tablets (0.2 mg) in a healthy 6-year-old 16.8-kg dog induced an episode of vomiting and hippus within 9 hours of ingestion. The dog was treated with activated charcoal and saline (magnesium sulfate) cathartic. Initially the serum concentration of thyroxine (T4) 4,900.9 nmol/L. On the second day, serum concentration of triiodothyronine (T3) was 5.3 nmol/L. Serum T4 concentration decreased slowly and was not determined to be normal until day 36. Serum T3 concentration was found to be normal on day 6. Serum alanine transaminase activity peaked on day 6 at 345 U/L. Significant abnormalities were not found during the following 36 days. Clinical signs of thyroid hormone toxicosis in dogs and cats include hyperactivity, lethargy, tachycardia, tachypnea, dyspnea, abnormal pupillary light reflexes, vomiting, and diarrhea. High overdoses of levothyroxine sodium in dogs should be managed by initial decontamination and administration of activated charcoal with a cathartic followed by supportive care.

Extracranial metastasis of primary central nervous system neoplasms is uncommon and has not been described in the dog. We report the clincopathologic features of intracranial meningioma with pulmonary metastasis in three dogs (case No. 1: 13-year-old castrated male Boxer dog; case No. 2: 14-year-old spayed female Dachshund; case No. 3: 6-year-old spayed female German Shepherd Dog). Case No. 1 presented with ataxia, lethargy, vomiting, and leaning and falling to the right, and had a transient remission following radiation and corticosteroid therapy; case No. 2 had a history of seizures that were unresponsive to primidone, left-sided postural reaction deficits, ataxia, and circling to the right; case No. 3 had only intermittent episodes of vomiting Computed tomography of case Nos. 1 and 2 revealed peripherally located homogeneous contrast-enhancing intracranial masses. Postmortem examination revealed intracranial masses with single or multiple pulmonary nodules in all three cases. Histologically, the intracranial and pulmonary masses were meningotheliomatous meningiomas with atypical features including brain infiltration, necrosis, nuclear atypia, prominent nucleoli, and moderate cell density. All of the primary meningiomas had low mitotic rates. The current interest in early diagnosis and aggressive clinical/surgical management of canine patients with meningioma and other primary central nervous system neoplasms will likely result in an increased detection of extracranial metastases.

Acivicin (AT-125) is a glutamine antagonist with dose-limiting, schedule-dependent CNS toxicity and predictable CSF penetration after intravenous administration. Because of these properties, a trial in CNS malignancies was initiated. Thirty-two patients with recurrent or residual malignant astrocytomas were treated with AT-125. The majority of patients had glioblastoma multiforme (24) and had received prior nitrosoureas (21). The median age was 50 years, and Southwest Oncology Group (SWOG) performance status was 2. The major determinant of response was based upon radiologic criteria using computed tomographic (CT) scanning and/or magnetic resonance imaging (MRI) scans. The tumor mass was measured in two perpendicular planes, which yielded the largest cross-sectional area. Standard solid tumor criteria for response were used. All responding patients also had a stable or tapered dose of corticosteroids with stable or improved performance status and neurologic examination. There were four objective responses (12%): one complete remission (3 1/2+ years) and three partial remissions (57, 86, and 322 days). Two patients had improvement in disease that did not meet requirements for a partial remission. Toxicity was mild and primarily consisted of nausea, vomiting, and lethargy. Two patients were removed from study due to neurotoxicity (depression and hallucinations). The strict response criteria used in this trial were not those that have been used in testing other active agents such as carmustine (BCNU). We conclude that AT-125 has objective antitumor activity in malignant astrocytomas and warrants further study.

The authors report their experience using esmolol, an ultra-short acting beta-adrenergic antagonist, for the treatment of seven patients with cocaine-associated cardiovascular complications. No consistent hemodynamic benefit was found with the use of this drug. Although there was a decline in mean heart rate of 23% (range 0% to 35%), they were unable to show a consistent antihypertensive response. Adverse effects occurred in three patients. This included one patient with a marked exacerbation of hypertension and one who became hypotensive. Another patient developed emesis and lethargy during esmolol therapy and required endotracheal intubation. They do not recommend the routine use of esmolol for cocaine cardiotoxicity.

A prospective study at two regional poison centers was undertaken in 500 children under six years of age (mean age 2.3 y) to resolve the question of whether milk has an effect on ipecac-induced emesis. When home administration of ipecac was recommended, parents were asked to select either milk or clear fluids. The mean volume of fluid +/- standard deviation administered was 159 +/- 72 mL in the milk group and 161 +/- 77 mL in the clear fluid group (p = 0.79). There was no difference in the onset of vomiting (23.4 +/- 18.5 vs. 23.3 +/- 12.9 min, p = 0.92), number of vomiting episodes (3.5 +/- 1.9 vs. 3.4 +/- 1.8, p = 0.65), or duration of vomiting (45 +/- 73 vs. 39 +/- 54 min, p = 0.31) for the milk group compared with the clear fluid group. Side effects including lethargy and diarrhea occurred with similar frequency in both groups. The substance ingested had no effect on onset of vomiting, vomiting duration or number of vomiting episodes. These findings again demonstrate that milk does not interfere with ipecac-induced emesis.

Fusaric (5-butylpicolinic) acid is a phytotoxin produced especially by Fusarium moniliforme, a mold commonly found in Canadian-grown corn. Experiments were conducted to determine the effects of acute doses of fusaric acid on brain neurochemistry and behavior in swine. A total of 40 crossbred barrows (initial weight 10 kg) were orally dosed with 0 or 200 mg of fusaric acid/kg of BW and five animals from each treatment were killed 4.5, 9, 18, or 36 h after dosing. All brains were dissected, and concentrations of indoleamine and catecholamine neurotransmitters and metabolites were determined. Animals in the group killed 36 h after dosing were observed for behavioral changes. Vomiting was noted in 60% of the pigs dosed with fusaric acid. These pigs also seemed more lethargic than controls and appeared sedated. The major neurochemical changes due to exposure to fusaric acid were seen in the hypothalamus 18 h after dosing. Brain tryptophan, serotonin, and 5-hydroxyindoleacetic acid all tended to be elevated by the action of fusaric acid. Brain catecholamine concentrations were largely refractory to treatment. It was concluded that exposure to acute doses of fusaric acid can cause vomiting and neurochemical changes in swine. Fusaric acid may, therefore, be acting synergistically with trichothecene mycotoxins to cause vomiting and feed refusal in pigs consuming trichothecene-contaminated feedstuffs.

Hydrocephalus is marked by the excessive accumulation of cerebrospinal fluid within the ventricles. The disorder is characterized by an imbalance in the production and reabsorption of cerebrospinal fluid. Congenital hydrocephalus is usually the result of an intrauterine infection or maldevelopment of the aqueduct of Sylvius. Acquired hydrocephalus can be caused by infection, neoplasm or hemorrhage. In infants, hydrocephalus usually presents as progressive head enlargement. The presenting symptoms in children are irritability, headache, nausea, vomiting and lethargy. Diagnosis is made with ultrasonography, computed tomography or magnetic resonance imaging. The majority of patients are treated with cerebrospinal fluid shunt procedures, most commonly the placement of ventriculoperitoneal or lumboperitoneal shunts. The outcome of hydrocephalus is determined by the etiology, the presence or absence of associated anomalies, and the timeliness of diagnosis and treatment.
