1/85. parathyroid hormone-related protein (PTH-rP)-associated hypercalcemia in a patient with an atypical chronic lymphocytic leukemia.We describe a patient with an atypical chronic lymphocytic leukemia (CLL) of the mixed cell type with a hypercalcemia due to parathyroid hormone-related protein production by the malignant B cells. On regard of the elevated serum calcium level without overt lytic bone lesions we found elevated serum levels of PTH-rP and demonstrated the presence of PTH-rP on the malignant lymphocytes. PTH-rP-related hypercalcemia in CLL is very rare. The role in PTH-rP in humoral hypercalcemia of malignancy is discussed.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
2/85. Marked histiocytosis in the portal tract in a patient with reactive hemophagocytic syndrome: An autopsy case.We report an autopsy case of reactive hemophagocytic syndrome with peculiar liver histology. A 71-year-old female was diagnosed as having acute myelogenous leukemia and treated with chemotherapy. During her course, methicillin-resistant staphylococcus aureus (MRSA) was noted in blood culture and she was diagnosed as having MRSA sepsis. She died of respiratory failure 5 months after the onset of leukemia and 10 days after the MRSA sepsis. Ante-mortem liver function tests were within normal ranges. At autopsy, myeloblastic leukemia cells positive for CD13 were present in the bone marrow and, to a much lesser extent, in the spleen and liver. Numerous histiocytes of a bland appearance with erythrophagocytosis were noted in the bone marrow and spleen. The histiocytes were positive for CD68, but negative for S-100 and lysozymes. In the liver, many histiocytes of bland appearance with erythrophagocytosis and CD68 positivity were present in the portal tracts with no Kupffer cell hyperplasia. There were no hepatocellular degeneration, fatty changes or sinusoidal dilations. We consider that this histiocytosis was associated with MRSA infection and diagnosed this as infection-associated hemophagocytic syndrome. In previously reported cases, hemophagocytosis in hyperplastic kupffer cells was the main liver change of reactive hemophagocytic syndrome. The present case suggests that marked histiocytosis in portal tracts only may be a main feature of liver changes in reactive hemophagocytic syndrome and that such cases may not show abnormal liver function tests.- - - - - - - - - - ranking = 0.60257543261138keywords = leukemia, myelogenous (Clic here for more details about this article) |
3/85. Substituting dexamethasone for prednisone complicates remission induction in children with acute lymphoblastic leukemia.BACKGROUND: The authors report the occurrence of fatal or near-fatal sepsis in 16 of 38 children with newly diagnosed acute lymphoblastic leukemia (ALL) treated with a new induction regimen that differed from its predecessor by the substitution of dexamethasone for prednisone. methods: The frequency of septic deaths among 38 children who received multiagent remission induction therapy, including dexamethasone (6 mg/m(2)) daily for 28 days (pilot protocol 91-01P), was compared with the frequency of septic deaths among children previously treated (protocol 87-01) and subsequently treated (protocol 91-01) in consecutive Dana-Farber Cancer Institute (DFCI) ALL trials with induction therapy that included 21 and 28 days of prednisone (40 mg/m(2)), respectively. Except for dexamethasone in protocol 91-01P, the remission induction agents used were identical in substance to those used in protocol 87-01. Protocol 91-01, the successor 91-01P, was also similar, with the exception of the deletion of a single dose of L-asparaginase. RESULTS: Sixteen of the 38 children (42%) treated on the DFCI 91-01P had documented gram positive or gram negative sepsis (17 episodes) during remission induction, including 4 toxic deaths (11%). In contrast, there were 4 induction deaths among 369 children (1%) treated on protocol 87-01 (P = 0.0035) and 1 induction death among 377 children (<1%) treated on protocol 91-01 (P = 0.0003). CONCLUSIONS: Substitution of dexamethasone for prednisone or methylprednisolone in an otherwise intensive conventional induction regimen for previously untreated children with ALL resulted in an alarmingly high incidence of septic episodes and toxic deaths. awareness of this complication, considering that the substitution has no apparent benefit in the efficacy of remission induction, argues against its routine use in intensive induction regimens for children with ALL.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |
4/85. Monocytic leukemia cutis diagnosed simultaneously with refractory anemia with monocytosis: a case report.A case of leukemia cutis (LC) of monocytic lineage in a patient with myelodysplastic syndrome (MDS) is presented. Cutaneous infiltrates were recognized concurrent with diagnosis of refractory anemia (RA) with monocytosis. skin infiltrates subsequently spontaneously regressed although MDS progressed with increasing monocytosis, anemia, and thrombocytopenia. death occurred 6 months after diagnosis with evolution of acute monoblastic leukemia complicated by sepsis. This case supports previous observations of poor prognosis associated with leukemia cutis. LC associated with MDS is reviewed including the role of monocytes.- - - - - - - - - - ranking = 1.4keywords = leukemia (Clic here for more details about this article) |
5/85. Involvement of the NUP98 gene in a chromosomal translocation t(11;20)(p15;q11.2) in a patient with acute monocytic leukemia (FAB-M5b).We report here a case of acute monocytic leukemia (M5b subtype according to the French-American-British [FAB] classification) with chromosomal translocation t(11;20)(p15;q11.2). fluorescence in situ hybridization analysis with a probe for the NUP98 gene, which is located at chromosome band 11p15, showed that the probe hybridized to both derivative chromosomes 11 and 20 as well as to the remaining normal chromosome 11, indicating that the NUP98 gene was split and involved in this translocation. This is the first report of t(11;20)(p15;q11.2) involving the NUP98 gene in overt leukemia.- - - - - - - - - - ranking = 1.2keywords = leukemia (Clic here for more details about this article) |
6/85. Recovery from bacillus cereus sepsis.A patient with acute leukemia developed two separate episodes of bacillus cereus septicemia during one hospitalization. leukopenia as a consequence of cytotoxic chemotherapy preceded both illnesses. The course of the infections was favorably influenced by the return of adequate numbers of circulating granulocytes and aminoglycoside therapy. Only one other compromised host is known to have recovered from this otherwise fatal disease.- - - - - - - - - - ranking = 0.2keywords = leukemia (Clic here for more details about this article) |
7/85. Acute promyelocytic leukemia in childhood. Report of a case with a review of the literature.A rare case of acute promyelcytic leukemia (APL) is reported in a 7-year-old boy. The patient displayed the typical features of APL including impaction of the marrow with promyelocytes, marked elevation of the serum vitamin B12 and transcobalamin I levels and a hemorrhagic diathesis. The bleeding diathesis in the case was due to thrombocytopenia, and there was no evidence for disseminated intravascular coagulation.- - - - - - - - - - ranking = 1keywords = leukemia (Clic here for more details about this article) |

9/85. Fournier's gangrene after unrelated cord blood stem cell transplantation.A 16-year-old boy with refractory acute myelogenous leukemia developed Fournier's gangrene as an early complication after two-antigen HLA-mismatched unrelated cord blood stem cell transplantation. On day 25 after the transplantation, he noted abrupt onset of penile swelling with miction pain. The penile inflammation rapidly extended posteriorly to involve the scrotum and perianal tissues, inferiorly to involve the thighs, and superiorly up the lower abdominal region within the next 36 h, and he died from sepsis on day 27. Fournier's gangrene presenting as a genitoperineal necrotizing fasciitis should be considered as a potential complication in umbilical-cord blood recipients in the cytopenic post-transplant phase.- - - - - - - - - - ranking = 0.20257543261138keywords = leukemia, myelogenous (Clic here for more details about this article) |
10/85. Acute myeloid leukemia complicated with staghorn calculus.An 11-year-old girl who presented with hyperleukocytosis accompanied by significant increases in serum uric acid and lactate dehydrogenase levels was discovered to be suffering from acute myeloid leukemia (AML). Subsequently a staghorn calculus was identified 22 months after the start of chemotherapy. The diagnosis of staghorn calculi was suggested by plain abdominal X-ray and ultrasonography. This paper describes the course of an adolescent patient with AML and focuses specifically upon her urological complications. To the best of our knowledge, this is the first reported pediatric case of AML complicated with staghorn calculi, which developed following repeated episodes of septicemia.- - - - - - - - - - ranking = 1.0500607442045keywords = leukemia, myeloid leukemia (Clic here for more details about this article) |
