The first case of canine ehrlichiosis in Connecticut is reported. A female Brittany spaniel from Milford presented with lethargy, anorexia, fever, petechiae, splenomegaly, thrombocytopenia, anemia, elevated serum alkaline phosphatase, lymphopenia, and hypoalbuminemia. Serologic analysis revealed antibodies to Ehrlichia canis (titer, 1:2,560). This documents a more northern geographic distribution in the United States for this infectious agent than had previously been suspected.

A case of chronic myelogenous leukemia (CML) with marked thrombocytosis and its megakaryokinetics were reported. Patient was 57-year old woman who had a marked thrombocytosis (1,413 x 10(3)/microliters) and a bone marrow megakaryocytosis. Bone marrow karyotype demonstrated Ph1 chromosome in all cells examined. However, on physical examination, there was no splenomegaly. CBC showed no immature myeloid cells, and neutrophil alkaline phosphatase was elevated. These manifestations were consistent with so called essential thrombocythemia (ET) with Ph1 chromosome reported by Nissenblatt. To know the megakaryokinetics of this case, we examined the number of colony forming unit-megakaryocyte (CFU-M), platelet glycoprotein (PGP) IIb/IIIa positive cells, cytoplasmic area, and DNA content, comparing with those of normal subjects, CML, and ET. We found a marked increase of CFU-M and PGP IIb/IIIa positive cells, but in contrast, decreased DNA content and cytoplasmic area. This pattern of megakaryokinetics was consistent with that of CML. We conclude that ET with Ph1 chromosome may be a variant of CML rather than ET itself.

A 22-year old male was admitted to Ashikaga Red Cross Hospital because of the progressing abdominal distension in May 1988. The physical examinations disclosed marked hepato-splenomegaly, lymphadenopathy and cachexic state. In the laboratory examinations, anemia, leukocytosis with left shift of nuclei and severe inflammatory reactions were found. Bone marrow aspirations were dry taps, and the biopsy showed myelofibrotic changes. Abdominal computed tomography and ultrasonography revealed a marked hepatomegaly and a giant splenomegaly with subcapsular hematoma. Philadelphia chromosome was negative and neutrophilic alkaline phosphatase score was slightly high. A little amount of peritoneal effusions was obtained and yielded S. aureus. A diagnosis of myelofibrosis with subcapsular hematoma due to spontaneous rupture of spleen and peritonitis of unknown cause was made. Operative indication was considered, but his family did not agree with it. Then conservative therapies for general conditions, those are, administrations of antibiotics and diuretics, and blood transfusions were taken. On the enlarged spleen, total irradiation was done. After the therapies, his spleen got smaller and hematoma was going to be absorbed. A rare case of myelofibrosis with splenic hematoma is reported and the conservative therapies were effective to this case.

Congenital agranulocytosis is a disorder characterized by severe neutropenia and a profound deficiency of identifiable neutrophil progenitors in bone marrow. In an attempt to stimulate neutrophil production and thereby reduce the morbidity and mortality associated with this disease, we administered recombinant human granulocyte colony-stimulating factor (rhG-CSF) in doses of 3 to 60 micrograms per kilogram of body weight per day to five patients with congenital agranulocytosis. In all five patients, an increase in the number of neutrophils was noted eight to nine days after the initiation of the effective dosage (the dose at which the neutrophil count reached 1000 cells per microliter or more and the bone marrow showed granulocyte maturation beyond the myelocyte stage). The absolute neutrophil counts rose from less than 100 to between 1300 and 9500 cells per microliter. Marrow aspirates obtained after 14 days at the effective dosage showed maturation to the mature neutrophil stage. The side effects that were observed were medullary pain, splenomegaly, and an elevation of levels of leukocyte alkaline phosphatase. All five patients have had sustained neutrophil counts of 1000 cells per microliter or more for 9 to 13 months while receiving subcutaneous maintenance therapy. Preexisting chronic infections have resolved clinically, and the number of new infectious episodes and the requirement for intravenous antibiotics have decreased. We conclude that treatment with rhG-CSF can lead to a large increase in the numbers of functional neutrophils in patients with congenital agranulocytosis.

A case of blastic transformation of essential thrombocythemia (ET) is reported. A 69-year-old male was first admitted to hospital because of fever in February, 1982. He was diagnosed as having ET because of marked thrombocytosis (205.5 x 10(10)/1), absence of erythrocytosis, absence of splenomegaly, normal karyotype and no increment of blasts in the bone marrow, and normal levels of neutrophil alkaline phosphatase, vitamin B12 and folate. He was treated with busulfan, and subsequently his platelet count was well controlled for about five years. At the second admission, blasts were present in the peripheral blood, and later accounted for 49% of the total leukocyte count. Histological examination of a bone biopsy specimen showed homogeneous proliferation of blastic cells and slight reticulin fibrosis. At autopsy, the degree of bone marrow fibrosis had increased. This was considered to be a very rare case of ET with blastic transformation in the terminal phase.

Bone marrow involvement was seen in 11 percent of patients with Hodgkin's Disease which was determined from pre-treatment biopsy specimens using established histopathologic criteria. Analysis of 32 evaluable patients with marrow involvement showed male preponderance with a peak in fourth decade of life. Twenty four cases (75%) had B-symptoms and 15 (46%) presented within six months of onset of symptoms. On categorizing for clinical staging, 21 (65%) belonged to stage III and IV. Hepatomegaly (greater than or equal to 2 cms) was present in seven cases (21%) and splenomegaly in 13 cases (40%). Mixed cellularity and lymphocytic depletion histopathologic subtypes showed the highest frequency of involvement (21 cases; 65%). Out of 28 cases ESR was raised in 27 cases (96%). Eighteen cases (56%) showed elevated serum alkaline phosphatase levels. Serum copper levels were determined in 14 cases, out of which 12 (85%) showed elevated levels. These parameters along with anemia (hemoglobin of 12 g/dl or less) in 26 cases (81%), correlated well with the disease activity. Only four cases had leukopenia at presentation pointing to no hindrance for aggressive chemotherapy. All cases received minimum of six courses of standard combination chemotherapy with or without local radiotherapy. Sixteen cases (50%) relapsed subsequently and were managed accordingly. A five year follow-up revealed a minimal 31 percent overall survival, and 18 percent of patients were disease free and well since the time of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Subacute thyroiditis is generally thought to be a self-limited inflammatory disease of the thyroid gland. This paper describes serial observations on the clinical course of a typical patient with subacute thyroiditis. This patient showed specific features of destructive thyrotoxicosis with increases in the serum levels of acute phase reactants and in the erythrocyte sedimentation rate. She also showed signs of liver dysfunction [slightly increased alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (gamma-GTP), and leucine aminopeptidase (LAP)], slight anemia, glucose intolerance, increased pancreatic enzymes, splenomegaly, and an increase in peripheral Leu 7 positive (NK/K) cells. These abnormalities all improved with recovery from disease. These findings indicate that in this patient with subacute thyroiditis inflammation is not limited to the thyroid gland but also involves the liver, pancreas and spleen. Thus the subacute thyroiditis in this patient may be a systemic multi-organ disease.

Phenytoin hepatotoxicity is a serious idiosyncratic reaction that occurs in less than one percent of patients. The onset of symptoms occurs early in therapy, usually within the first six weeks. Presenting symptoms often include fever, rash, lymphadenopathy, hepatomegaly, anorexia, and myalgias or arthralgias. Other significant findings that may develop throughout hospitalization are jaundice, periorbital or facial edema, and splenomegaly. The following alterations in liver function tests are associated with phenytoin hepatotoxicity: elevations in serum aminotransferases, lactic dehydrogenase, alkaline phosphatase, bilirubin, and prothrombin time. Rechallenges, lymphocyte stimulation test, and liver biopsy have been used to aid in the diagnosis. Rechallenge is the most definitive diagnostic approach; however, its use is limited by the potential of a fatal reaction. Although the exact mechanism of phenytoin hepatotoxicity is unknown, the majority of literature supports a hypersensitivity mechanism. The severity of this adverse effect ranges from self-limiting to fatal. Since 1965 six fatal cases have been reported. To date, sufficient evidence is not available to establish treatment guidelines. Discontinuation of phenytoin therapy is warranted.

The occurrence of polycythemia vera in a father, mother, and two sons is reported. Thirteen kindreds with familial polycythemia vera in 31 members are reviewed. Comprehensive records were available for all four patients as well as other family members, since all were diagnosed and treated at the author's institution over a period of nearly 50 years. The mean age at diagnosis, sex predominance, symptoms, and incidence of chromosomal abnormalities, leukocytosis, thrombocytosis, and elevated leukocyte alkaline phosphatase levels were similar to those of nonfamilial cases. The mean RBC volume at diagnosis and the incidence of splenomegaly appear to be higher in familial than nonfamilial cases. The mode of inheritance is unclear, but genetic factors may be involved in the pathogenesis of this myeloproliferative disorder.

A 33-year-old female was admitted to St. Marianna University hospital in April 1983 for the purpose of examination for leukocytosis. Physical examination revealed a marked splenomegaly. The white cell count was 174 x 10(9)/l. The hemoglobin was 9.0 g/dl and the platelet was 790 x 10(9)/l. Microscopical examination of aspirated specimen of bone marrow revealed hypercellularity with granulocytic hyperplasia. The chromosomal analysis of bone marrow cells showed Philadelphia chromosomes in all metaphases analyzed. The neutrophil alkaline phosphatase activity was reduced. A diagnosis of CML was made. She was treated with busulfan in a dose of 2 mg/day until the white cell count was 14.5 x 10(9)/l. She has been followed without any therapy and clinical remission state has been continued. In April 1985, the chromosomal analysis of bone marrow cells revealed the recovery of normal karyotype hemopoiesis in 57% of metaphases analyzed. These findings of this case suggest that some of Ph1-positive cells may reduce their growth advantage over normal cells without any bone marrow hypoplasia.
