An 11-month-old female Vietnamese pot-bellied pig was examined for severe dehydration and neurologic signs including disorientation, ataxia, blindness, and involuntary twitching of the muscles of the neck and head. Biochemical analyses of serum revealed hypernatremia, hyperchloremia, hyperkalemia, azotemia, hyperphosphatemia, hyperalbuminemia, and high activities of aspartate transaminase and creatine kinase. A diagnosis of salt toxicosis/water deprivation was made. Medical management consisted of intravenous administration of a high-sodium crystalloid solution, anti-inflammatory drugs, and other supportive care. Sodium concentration of fluids administered intravenously was adjusted to be slightly less than the pig's serum sodium concentration so that the serum sodium concentration was reduced gradually over 48 hours. Resolution of clinical signs was rapid and the pig was discharged after 8 days of hospitalization. Fourteen days after the initial examination, the pig appeared healthy except for visual deficits. Historically, prognosis with conventional treatment of salt toxicosis/water deprivation is poor; however, this alternative approach to treating this condition appears promising.

We have developed a group of 4-substituted-1-nitroacridines with potent anti-tumor activity against prostate cancer and less toxic than parent 1-nitroacridines. The most active 9-(2'-hydroxyethylamino)-4-methyl-1-nitroacridine (C-1748) was selected for pre-clinical studies. The current study was undertaken to evaluate clinical and/or morphological adverse effects of C-1748 as a single intravenous dose at concentrations ranging from 0.16 to 4.6 mg/kg administered to male Beagle dogs. The maximum tolerated dose was 1.5 mg/kg. Emesis was observed in all groups lasting an average of 30 min to 12 h post-dosing. At high dose, extreme aggression was observed in one dog followed by disorientation and depression lasting for 48 h a frequent observation with chemotherapy. Reductions in platelets and white blood cells were observed which was similar to that seen with other chemotherapeutic agents. A compensatory hyperplasia of lymph nodes and a transient and limited extravasation in the intestinal mucosa were also observed. Increases in aspartate aminotransferase, alkaline phosphatase and creatine phosphokinase were transient with normal levels restored by day 9. These enzyme increases were accompanied by epithelial hypertrophy of larger bile ductules in the periportal triads of the liver. The low toxicity profile and high tumor target activity make this novel class of drug a promising chemotherapeutic agent.

A 74-year-old man with depressive symptoms was admitted to a psychiatric hospital due to insomnia, loss of appetite, exhaustion, and agitation. Medical treatment was initiated at a daily dose of 20 mg paroxetine and 1.2 mg alprazolam. On the 10th day of paroxetine and alprazolam treatment, the patient exhibited marked psychomotor retardation, disorientation, and severe muscle rigidity with tremors. The patient had a fever (38.2 degrees C), fluctuating blood pressure (between 165/90 and 130/70 mg mm Hg), and severe extrapyramidal symptoms. Laboratory tests showed an elevation of creatine phosphokinase (2218 IU/L), aspartate aminotransferase (134 IU/L), alanine aminotransferase (78 IU/L), and BUN (27.9 mg/ml) levels. The patient received bromocriptine and diazepam to treat his symptoms. 7 days later, the fever disappeared and the patient's serum CPK levels were normalized (175 IU/L). This patient presented with symptoms of neuroleptic malignant syndrome (NMS), thus demonstrating that NMS-like symptoms can occur after combined paroxetine and alprazolam treatment. The adverse drug reaction score obtained by the Naranjo algorithm was 6 in our case, indicating a probable relationship between the patient's NMS-like adverse symptoms and the combined treatment used in this case. The involvement of physiologic and environmental aspects specific to this patient was suspected. Several risk factors for NMS should be noted in elderly depressive patients whose symptoms often include dehydration, agitation, malnutrition, and exhaustion. Careful therapeutic intervention is necessary in cases involving elderly patients who suffer from depression.
