Treatment of valproate tremors.

Chronic valproate therapy induces symptomatic tremor in about 10% of patients. We studied the effects of propranolol, amantadine, diphenhydramine, benztropine, and cyproheptadine on these tremors in 19 patients by using serial accelerometric recordings. Propranolol was clearly the most therapeutic. Amantadine was moderately effective, but cyproheptadine, diphenhydramine, and benztropine gave little or no relief.

Valproate tremors.

We made accelerometric recordings of the tremor induced by valproic acid. The tremor was similar to essential tremor and appeared within a month of starting therapy. It was present at rest and exacerbated by action or antigravity positioning. There was no close correlation of tremor severity and plasma valproate level, but the tremor usually appeared at dosages greater than 750 mg per day. This tremor has appeared in 20 of 25 patients recently studied. In some patients the tremor is markedly active; however, others note only minimal tremor activity.

Myeloproliferative disorder in a t(13q14q) carrier.

A Robertsonian balanced translocation of two D chromosomes was found in the bone marrow cytogenetic studies of a 70-year-old myeloproliferative disorder (MPD) woman. G-banding studies showed the translocation involved a 13q14q. An identical balanced t(13q14q) chromosomal pattern was found in her peripheral blood 3 years before the diagnosis of MPD as part of an investigation involving her daughter's reproductive difficulties. Her daughter is also a t(13q14q) balanced translocation carrier. The finding of a t(13q14q) in MPD may be coincidental or it may be predisposing to the development of MPD. Additional studies may elucidate this controversy.

Clinical efficacy and long-term effects of valproic acid therapy on spike-and-wave discharges.

Twenty-two patients with absence seizures and other seizure types were treated with valproic acid and followed up for 1 year. Results were excellent with more than 75% improvement in 80% of patients with absence seizures, in 40% of those with tonic-clonic seizures, in all of those with myoclonic seizures, and in 43% of those with partial seizures. Fifty-seven percent of the patients had more than a 75% reduction in the total number of paroxysmal spike-wave discharges, and 62% had more than a 75% reduction in the number of spike-wave discharges lasting longer than 3 seconds. Photosensitivity and activation by hyperventilation decreased. More patients achieved good EEG control in 1 year than in 10 weeks.

Waldenström's macroglobulinemia and autoimmune disease in a family.

We diagnosed Waldenström's macroglobulinemia in a father and three offspring. Clinical and subclinical autoimmune disorders occurred excessively in the family. The HLA haplotype A2, B8, DRw3 was detected in all patients with Waldenström's macroglobulinemia and all but one family member with autoimmune manifestations. A lod score [log odds] of 4.86 favors linkage to the HLA complex of a gene predisposing to lymphoproliferative and autoimmune disorders. Associated with this HLA haplotype were the B-cell alloantigens Ia-172 and 350, previously reported in patients with the lymphoma-prone sicca syndrome.

Acquired hemoglobin H disease in idiopathic myelofibrosis.

A 68-year-old male, diagnosed 1 year previously as having myelofibrosis, developed hemolysis, red cell inclusions, and 37% Hb H. The alpha/beta globin synthetic ratio for circulating reticulocytes, determined by 3H-leucine incorporation and globin chain separation by carboxymethylcellulose chromatography in urea, was 0.049. When total RNA was purified from peripheral blood cells and translated in a wheat germ cell-free translation system, the alpha/beta ratio of the translation products was 0.26, indicating mRNA as a major cause of the globin synthetic imbalance. This study demonstrates that myelofibrosis is one setting in which acquired Hb H disease occurs; that the synthetic imbalance may be extreme; and that it can be associated with an imbalance in the activities of specific globin mRNAs.

Effect of valproic acid on spike and wave discharges in patients with absence seizures.

Twenty-five patients with absence seizures were treated with valproic acid in doses from 17 to 62.5 mg per kilogram per day. Nineteen patients experienced reduction of spike and wave discharges; in 11 it was greater than 75 percent. Twenty-one patients had a reduction of the total time of spike and wave discharge. Four patients had increase of spike and wave discharges. Nineteen patients had fewer absence seizures. There was no correlation between plasma concentration of valproic acid and EEG change, but clinical improvement occurred when plasma levels of valproic acid reached 50 to 60 microgram per milliliter.

Adult acute leukemia. The Rochester (NY) Experience.

A ten-year retrospective study of adult acute leukemia was performed in nonieukemia-specialized centers to determine prognostic factors, length and quality of survival, cause of death, and response to different modes of therapy. Of 200 patients, 9.5% achieved complete remission, 14.0% obtained partial remission, and no response was present in 76.5%. Patients who were 50 years old or more (64.5%) had a significantly lower response rate (P less than .005) and survival (P less than .05) than the younger age group. Aggressive chemotherapy significantly improved the response rate, as well as survival (P less than .001). Quality of life was similar for responders and nonresponders, both spending only one fourth of their survival time in the hospital. Infection as the leading cause of death. The overall ten-year response rate of 23.5% represents a realistic rate in nonleukemia-specialized centers in which the treatment of adult acute leukemia is variable.

Lymphocytic choriomeningitis in university hospital personnel. Clinical features.

Clinical manifestations of lymphocytic choriomeningitis (LCM) virus infection in 15 patients are described. These patients were University Hospital personnel who had had contact with hamsters, subsequently shown to harbor the virus. Fever with striking myalgias, headache and rigors were the most common symptoms. Only 2 of the 15 patients had clinically overt and documented aseptic meningitis. Leuikpenia was observed in 10 of 11 patients and thrombocytopenia in 8 of 8 patients tested. A biphasic illness was seen in eight patients. In a patient who has been exposed to laboratory animals, particularly to hamsters, a nonspecific influenza-like febrile illness accompanied by leukopenia and thrombocytopenia may represent LCM virus infection.

Perivascular hemosiderin deposition in muscle in Waldenström's macroglobulinemia.

A 63-year old woman with Waldenström's macroglobulinemina of 5 years' duration developed disabling pain in her extremities. The patient had required frequent plasmapheresis and transfusion for treatment of hypervisosity. Muscle biopsy from 2 separate sites showed striking deposition of hemosiderin in macrophages surrounding small vessels and features of slight denervation. Immunofluorescence demonstrated IgM deposition in vessel walls. Perivascular hemosiderin deposition in muscle has not previously been desicribed and may reflect traansfusion-hemosiderosis in a patient with a dysglobulinemia.
