Chronic neutrophilic leukemia is a rare, infrequently recognized, myeloproliferative disorder. It usually manifests as a leukemoid reaction, with mostly mature granulocytes in the peripheral blood, with rare to occasional immature forms, and sometimes with normoblasts. The clinical manifestations also include hepatosplenomegaly, elevated leukocytic alkaline phosphatase, elevated serum vitamin B12 and serum vitamin B12 binder ("R" fraction), and elevated serum uric acid. Distinction from a leukemegaly, the absence of sepsis, usually normal erythrocytic sedimentation, and the absence of fever. Leukemoid reactions may be associated with elevated serum vitamin B12 and uric acid, but the levels are usually lower than those found in chronic neutrophilic leukemia. Many patients have gouty symptoms, especially after treatment with Busulfan, and many have an unexplained hemorrhagic tendency, making major operations a risk. The authors add two cases to the 11 previously described.

We have analyzed the indications and results of shunt operation versus orthotopic liver transplantation (OLT) in 22 patients with Budd-Chiari syndrome (BCS). The underlying cause of the syndrome was similar between the two groups and was related to myeloproliferative disorders or the use of birth control pills in 18 of 22 patients. The results of biopsies of the liver showed centrilobular congestion and necrosis in all candidates who underwent shunting and the presence of fibrosis and cirrhosis in the OLT candidates. The indications for shunts included symptoms related to portal hypertension only and well-preserved synthetic hepatic function. Ten patients were treated with 12 shunt procedures, including mesoatrial (eight patients) and side to side portacaval shunt (four patients). Significant complications after shunt procedure included fulminant (one of ten patients) and progressive (one of ten patients) hepatic failure requiring urgent OLT; one death occurred because of pulmonary sepsis. Indications for OLT were signs of end stage liver expressed by severe portal hypertension and variceal bleeding (four of 14 patients), progressive encephalopathy (seven of 14 patients) and poor synthetic function (bilirubin greater than 3 milligrams per deciliter in eight of 14 patients and albumin less than 3.0 grams per liter, or both, in ten of 14 patients). Fourteen patients were treated with 16 OLT, three patients had retransplantation for primary nonfunction graft (two of 14 patients) or chronic rejection (one of 14 patients). There were two early deaths in the group. With a follow-up period between two months to five years, 12 of 14 patients undergoing OLT are alive, fully functional and have normal liver function tests. Seven of ten patients who had shunts are alive, six are able to maintain normal activity and one has progressive end stage hepatic disease and is not a candidate for OLT. However, the hepatic function continues progressively to be abnormal. Various options are available for the treatment of the syndrome. Portosystemic decompression is effective and should be considered at the early stage of the disease, prior to the development of significant hepatic failure. However, few of the patients will continue to have slow, but progressive hepatic failure and may require OLT. The only effective treatment for end stage hepatic disease secondary to the BCS is OLT.

Dental disorders have been recognized as major sources of infection in patients with hematologic malignancies (HM). Management of severe dental infections usually includes dental extractions (DE), but the safety of extractions in patients with HM who are at risk for bleeding, sepsis, and poor wound healing has not been well established. In conjunction with an aggressive program of dental care, 142 DE were performed in 26 patients with acute leukemia, myelodysplastic syndromes, and myeloproliferative disorders. Granulocytopenia (less than 1,000 granulocytes/microL) was present during or within ten days following surgery in 14 patients. In these 14 patients (101 DE), the mean granulocyte count was less than 450/microL, with a median duration of granulocytopenia following surgery of 32 days (range, four to 169 days). Thrombocytopenia (less than 100,000 platelets/microL) occurred during or within two days following surgery in 13 patients (80 DE), with a mean platelet count of 63,500/microL. Transfusions were given for platelet counts less than 50,000/microL. All DE were performed without significant complications. Bleeding was minor to moderate and easily controlled with local measures; no patient required transfusion due to hemorrhage. Average maximum temperature 24 hours after DE was 37.7 degrees C. No episodes of bacteremia were documented within ten days of DE. Minor delay in wound healing was observed in two patients. We conclude that DE can be safely performed in patients with HM in combination with aggressive supportive care.

A 16 year review of 391 splenectomies performed at New England Medical Center was done to evaluate the morbidity and mortality of patients with drained splenic weights greater than 1,000 grams. Thirty-six met the criteria for study. Twenty men and 16 women with an average age of 55.4 years were identified. Myeloproliferative disorders were the most predominant cause of massive splenomegaly. Pancytopenia and hemolytic complications of the disease processes were the most acute indications for operations. The average time between diagnosis and operative intervention was 42 months. An average of 10 units of blood products were required to correct preoperative coagulopathy. Eleven of 36 patients had postoperative complications. Eight of 21 with drains and an equal number of patients with preliminary splenic arterial ligation had complications. Eight-one per cent of all complications were infection related. Complication increased the length of stay 11 days. The 30 day mortality rate was 11.1 per cent. Sepsis was the major cause of mortality. Closed drainage system provided no demonstrable benefit nor appeared to be the cause of sepsis. No episodes of pulmonary embolic phenomenon or peripheral venous thrombosis were demonstrated. Elective splenectomy in patients with smaller spleens was performed without operative mortality and with 3 per cent morbidity rate. For patients with massive splenomegaly, the average survival time was 28.5 months. The majority of these patients died from complications of the disease. Preoperative coagulopathy, failure to demonstrate a hematologic response to splenectomy and reoperation were clear predictors for decreased long term survival periods.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty patients (age range, 4 to 48 years; median age, 36 years) with de novo or drug-induced myelodysplastic syndromes or myeloproliferative disorders were treated with myeloablative immunosuppressive therapy followed by bone marrow transplantation (BMT). Four preparative regimens were used; three regimens consisted of combined total body irradiation (TBI) and chemotherapy and one of combination chemotherapy only. One patient received marrow from his identical twin brother, whereas the other 19 patients were grafted with marrow from histocompatible siblings. In 19 patients the abnormal clone was at least temporarily ablated, while in one patient the congenital myelodysplasia persisted. Eight patients are alive and well for +108 to +3,359 days post-transplantation. Nine patients died of transplant-related complications (six of interstitial pneumonia, two of gastrointestinal bleeding, and one of fungal sepsis) and three patients died with persisting or recurring disease. One patient with a late recurrence has undergone a second successful bone marrow transplant procedure. Outcome of BMT was not related to French-American-British (FAB) type, marrow fibrosis, cytogenetic abnormalities, or preparation regimen. Marrow transplantation as a means of providing long-term disease-free survival and possible cure should be considered in patients if a suitable donor is available.

Classification of platelet disorders has been based on the platelet count. Addition of a second variable, mean platelet volume (MPV), to the routine blood count allows classification of patients into 9 categories: high, low, or normal MPV, and high, low or normal platelet count. We studied 1,244 adult inpatients. 1,134 had both platelet values normal. 11 patients had high MPV and low platelet count: all had hyperdestructive causes. 15 patients had high MPV and normal platelet count: 12 had heterozygous thalassemia, and three had iron deficiency. Seven patients had high MPV and high platelet count: causes included myeloproliferative disorders, inflammation, iron deficiency, and splenectomy, 25 patients had high platelet counts and normal MPV: the causes were inflammation, infection, sickle cell anemia, iron deficiency, or chronic myelogenous leukemia. 52 patients had an MPV that was inappropriately low for the platelet count (high, normal, or low). All had sepsis, splenomegaly, aplastic anemia, chronic renal failure, or a disease being treated with myelosuppressive drugs. High MPV thus appears correlated with myeloproliferative disease or thalassemia; and low MPV, with cytotoxic drugs or marrow hypoplasia. Addition of MPV to the platelet count allows subtler disorders to be detected (when the platelet count is normal), and allows distinction of the cause of thrombocytopenia.

A 66-year-old female patient complained of loss of body weight and fatigue. The clinical examination revealed a thrombocytosis with a maximum count of 3.200 . 10(9) platelets and a leukocytosis with maximally 25 . 10(9) white cells in the peripheral blood. The bone marrow showed a large increase of megakaryocytes. Under the diagnosis of megakaryocytic myelosis a chemotherapy with 186 mg busulfan was performed. In the course of this treatment the clinical picture of a sepsis occurred which could not be controlled by antibiotics. The patient died four months after her admission to the clinic. The essential findings in autopsy were a caseous tuberculosis of the lymph nodes with haematogenic generalization which appeared as a septic tuberculosa gravissima ("typhobacillosis" Landouzy). The bone marrow was atrophic. Spleen liver and lymph nodes were without evidence for a myeloproliferative disorder. Thus, the initial diagnosis had to be changed to a megakaryocytic pseudomyelosis with massive thrombocytosis as a reaction to the tuberculous infection. The differential diagnosis of megakaryocytic myelosis, other disorders of the myeloproliferative syndrome, and the reactive thrombocytosis are discussed.

Two cases of acute leukemia with a t (6;9) (p23;34) chromosome abnormality are reported. The first case was a 34-year-old female who was hospitalized in October 1989. A diagnosis of FAB-M1 was made. Chromosomal analysis of the bone marrow cells showed a 46, XX, t (6;9) (p23;q34). Complete remission was achieved after two courses of BHAC-DMP therapy. In September 1991, at the time of relapse, chromosomal analysis revealed two abnormal clones consisting of a 46, XX, t (6;9) (p23;q34), -12, -17, +der (12) t (12;17) (p11.2;q11.2) with a residual normal clone. She died in February 1992. The second case was a 42-year-old male who was hospitalized in January 1990. He was diagnosed as having RAEB. Chromosomal analysis of the bone marrow cells showed 46, XY, t (6;9) (p23;q34). Three months later, the disease progressed to acute leukemia accompanied by leg ulceration with leukemic cell infiltration. Small-dose ara-C therapy was given, but with no effect. After two subsequent courses of therapy with low-dose etoposide, complete remission was achieved. Four months later, relapse occurred, and the patient died of sepsis in February 1991. In the literature, 31 cases of myeloproliferative disorders with t (6;9) have been reported.

There has been an increase in the indications for splenectomy for hematologic diseases. It is a consequence of expanding the list of disorders and liberalizing the indications for splenectomy for many diseases. Hereditary spherocytosis is the most frequently encountered congenital anemia for which splenectomy is curative. Splenectomy is generally advised for warm antibody acquired hemolytic anemia if conventional medical therapy fails. Idiopathic thrombocytopenic purpura (ITP) remains the most common hematologic disorder for which splenectomy is therapeutic. A variety of thrombocytopenias are improved by splenectomy. The myeloproliferative disorders constitute a spectrum of disease potentially improved by splenectomy, but preoperative management should be modified in this group. Splenectomy in patients with chronic leukemias and lymphomas are often palliative and facilitate chemotherapy. There are no specific requirements preoperatively other than the administration of pneumococcal and Hemophilus influenzae vaccines. Platelets are not administered to patients with ITP. An integral part of the procedure is the search for accessory spleens. The postoperative complication of overwhelming postsplenectomy sepsis must be considered; it occurs more frequently in association with specific basic diseases and can be obviated by appropriate treatment.

Budd Chiari syndrome is a rare disorder resulting from occlusion of hepatic venous drainage by hepatic vein thrombosis or by a membranous web in the inferior vena cava. In western countries the commonest causes are myeloproliferative disorders and hypercoagulable states. Presentation may be acute with rapid accumulation of ascites and hepatic failure, or subacute with symptoms developing over a few months. A chronic progressive form has also been described. On presentation there is usually abdominal pain, ascites, and hepatosplenomegaly; hepatic encephalopathy is found in about a third. Noninvasive, ultrasound-Doppler is recommended in diagnosis, and has a high correlation with hepatic venography. Liver biopsy is required for therapeutic decisions. Those with advanced hepatic failure or severe fibrosis on liver biopsy are referred for hepatic transplantation. When biopsy shows only hepatic congestion and inflammatory infiltrates, portosystemic shunting is recommended. We present a 61-year-old woman with ascites and hepatosplenomegaly that had developed over the courses of a few months. Budd-Chiari syndrome with chronic myelofibrosis and congenital protein C deficiency were diagnosed. Portosystemic shunt was performed but death from sepsis followed shortly.
