Improving multimodal physical function in adults with heterogeneous chronic pain; Protocol for a multisite feasibility RCT.

Background: Chronic pain is associated with substantial impairment in physical function, which has been identified as a top concern among persons with pain. GetActive-Fitbit, a mind-body activity program, is feasible, acceptable, and associated with improvement in physical function among primarily White, sedentary individuals with pain. In preparation for a multisite efficacy trial, we must examine feasibility across multiple sites with diverse patient populations.

[Immunophenotyping in adult acute myeloid leukemia: which prognostic value?].

Background: Immunophenotyping is an essential step in the diagnosis of acute myeloid leukemia. Its prognostic value remains controversial with contradictory results.

Aim: To assess prognostic impact of the immunophenotyping in AML.

Cytogenetic profile of a large cohort of Tunisian de novo acute myeloid leukemia.

Background: Cytogenetic data are essential not only for the diagnosis of acute myeloid leukemia but also for the evaluation of prognosis. Large systematic studies of cytogenetic aberrations in patients with acute myeloid leukaemia (AML) from Arab countries are not available.

Methods: We analysed 631 consecutive newly diagnosed AML patients by conventional cytogenetics and compared our results with reports from other regions of the world.

Treatment of Acute Promyelocytic Leukemia with AIDA Based Regimen. Update of a Tunisian Single Center Study.

In Tunisia, the ATRA era began in 1998 with the use, consecutively, of two regimens combining ATRA and an anthracycline with cytarabine (APL93), and without cytarabine (LPA99). From 2004, 51 patients with confirmed APL either by t(15;17) or PML/RARA were treated according to the PETHEMA LPA 99 trial. Forty three patients achieved CR (86%).

Risk factors of septic shock in patients with hematologic malignancies and Pseudomonas infections.

Pseudomonas is a clinically significant and opportunist pathogen, usually associated in causing high mortality nosocomial infections. The aim of this study was to determine the risk factors associated with septic shock in patients diagnosed with hematologic malignancies and Pseudomonas infections. A total of 80 Pseudomonas isolates (77 Pseudomonas aeruginosa) were collected from 66 patients aged 2-64 years: 52 with acute leukemia (79%), 7 with lymphoma (10.

ATRA and anthracycline-based chemotherapy in the treatment of childhood acute promyelocytic leukemia (APL): A 10-year experience in Tunisia.

Reports on childhood APL from developing countries are scarce. We treated 65 APL with two consecutive trials combining ATRA and chemotherapy. Twenty (30.

Treatment of acute promyelocytic leukemia with PETHEMA LPA 99 protocol: a Tunisian single center experience.

Acute promyelocytic leukemia (APL) has now become the most curable of all subtypes of acute myeloid leukemia. A cure rate of 75-80% can be anticipated with a combination of all-trans retinoic acid (ATRA) and anthracyclines. In Tunisia, the ATRA era began in 1998 with the use, consecutively, of two regimens of a combination of ATRA with anthracycline and cytarabine (APL93), and without cytarabine (LPA99).

Recurrent differentiation syndrome or septic shock? Unresolved dilemma in a patient with acute promyelocytic leukemia.

Differentiation syndrome (DS) is a life-threatening complication observed in patients with acute promyelocytic leukemia (APL) receiving induction therapy with all-trans-retinoic acid (ATRA). A bimodal incidence of DS has been observed, with a majority of cases occurring during the first week of ATRA treatment ("early" DS), but a substantial number of cases occurring during the third or even fourth week of ATRA treatment ("late" DS). However, to our knowledge occurrence of both early and late DS in the same patient has not been reported.

Factors associated with severe sepsis: prospective study of 94 neutropenic febrile episodes.

Severe sepsis defined as infection-induced organ dysfunction or hypoperfusion abnormalities predispose to septic shock and increased mortality in neutropenic setting. We aimed at determining predictors of severe sepsis in neutropenic patients. Between 1 October and 31 December 2007, 41 patients (21 with acute myeloid leukemia, 19 with acute lymphoid leukemia and one with autologous stem cell transplantation for a mantle cell lymphoma) with chemotherapy-induced neutropenia (<0.

High body mass index is an independent predictor of differentiation syndrome in patients with acute promyelocytic leukemia.

Increased BMI has been correlated to an increased incidence of APL, but not to the occurrence of differentiation syndrome (DS) in APL. We consecutively treated 39 APL patients with ATRA and idarubicin (according to PETHEMA regimen). Median age was 26 years.

Transfusion-related acute lung injury (TRALI) during remission induction course of acute myeloid leukemia: a possible role for all-transretinoic-acid (ATRA)?

Transfusion-related acute lung injury (TRALI) is a clinical syndrome characterized by sudden onset of respiratory distress due to pulmonary edema during or following transfusion. Two proposed pathophysiologic mechanisms for TRALI were proposed: the antibody hypothesis and the two-event hypothesis. The two-event hypothesis postulates that a pathway to neutrophil activation and aggregation can occur without leukocyte antibodies.

Predictive factors of all-trans-retinoic acid related complications during induction therapy for acute promyelocytic leukemia.

Background: The combination of all-trans-retinoic acid (ATRA) and chemotherapy has made acute promyelocytic leukemia (APL) a highly curable leukemia. However, several complications are reported with this treatment the most serious and life threatening being Retinoic Acid Syndrome (RAS). We aimed at identifying factors that could predict complications caused by ATRA during induction treatment of APL.

A first case of congenital TTP on the African continent due to a new homozygous mutation in the catalytic domain of ADAMTS13.

Hereditary thrombotic thrombocytopenic purpura (TTP) is a rare disorder characterized by occlusive microvascular thrombosis, consumptive thrombocytopenia, and microangiopathic hemolytic anemia. Homozygous or compound heterozygous mutations in the ADAMTS13 gene result in a congenital severe ADAMTS13 deficiency and subsequent accumulation of ultra-large von Willebrand factor multimers, which tend to form platelet thrombi in the microcirculation. We report a first case of congenital TTP on the African continent with a new, homozygous mutation in the metalloprotease domain of ADAMTS13.

Quantitative detection of bcr-abl transcripts in chronic myeloid leukemia.

The optimal management of malignant haematological disorders depend on the degree of tumor load reduction after therapy. Chronic myeloid leukemia constitutes a clinical model for molecular detection and therapy surveillance of malignant disease since this entity was the first leukemia shown to be associated with a specific bcr-abl fusion gene in the patient's leukemia cells. Molecular monitoring of bcr-abl transcript levels by real-time quantitative PCR is increasingly used to assess treatment response in patients with chronic myeloid leukemia (CML).

Secondary chronic myelomonocytic leukemia with monosomy 7 after successful treatment of acute promyelocytic leukemia.

Current APL chemotherapy protocols usually include high-dose anthracyclines, mitoxantrone, and epipodophillotoxins, which are topoisomerase II inhibitors of high leukemogenic potential. In the last years, several case reports of myelodysplastic syndrome (MDS) or AML (different from APL), occurring during the course of APL have been made. We report herein a first case of CMML with monosomy 7 occurring after treatment of APL.

Self-perception of health and fitness among French and Tunisian men and women.

This work examines the effects of sex and culture on physical self-perceptions. The aim was to compare the perception of physical fitness of French and Tunisian men and women. 400 individuals ages 20 to 35 years assessed their own fitness, endurance, strength, flexibility, body composition, and health according to specific category scales by completing a questionnaire.

Single autologous stem-cell transplantation followed by maintenance therapy with thalidomide is superior to double autologous transplantation in multiple myeloma: results of a multicenter randomized clinical trial.

From April 2003 to December 2006, 195 patients with de novo symptomatic myeloma and younger than 60 years of age were randomly assigned to receive either tandem transplantation up front (arm A, n = 97) or one autologous stem-cell transplantation followed by a maintenance therapy with thalidomide (day + 90, 100 mg per day during 6 months) (arm B, n = 98). Patients included in arm B received a second transplant at disease progression. In both arms, autologous stem-cell transplantation was preceded by first-line therapy with thalidomide-dexamethasone and subsequent collection of peripheral blood stem cells with high-dose cyclophosphamide (4 g/m(2)) and granulocyte colony stimulating factor.

[Hemoglobin C disease: report of 16 Tunisian cases].

Aim: was to provide the clinical and biological patterns hemoglobine disease in Tunisia.

Methods: This retrospective study collected to 16 cases of hemoglobin C disease : 6 homozygotic Hb C and 10 heterozygotic Hb C/beta-thalassemia.

Results: The clinical profile is characterized by mild hemolytic anemia (Hb = 11.

[Tumor lysis syndrome].

Tumor lysis syndrome is a potentially life threatening oncologic emergency that requires immediate medical intervention. The syndrome results from the destruction (or lysis) of a large number of rapidly dividing malignant cells spontaneously or during chemotherapy. The resulting metabolic abnormalities include hyperkaliemia, hyperuricemia, and hyperphosphatemia with secondary hypocalcemia, all of which put patients at risk for renal failure and alteration in cardiac function.

Isolated extramedullary relapse in the breast of a patient with acute myeloid leukemia following allogeneic stem cell transplantation: case report and review of the literature.

We report an unsual case of a woman with acute myeloid leukemia who showed an isolated extramedullary relapse (IEMR) in the breast following allogeneic stem cell transplantation and review the related literature. Eighty cases of IEMR following allogeneic stem cell transplantation, including our case, were identified. The review suggests that an M2 or M4 phenotype in the French-American-British classification and a favorable cytogenetic risk group are more frequently associated with the occurrence of IEMR.

[Therapeutic results with apl 93 protocol in acute promyelocytic leukemia (34 cases)].

Background: Acute promyelocytic leukaemia (APL) account for approximately 10% to 15% of all AML in most reports. Clinical features includes the presence in 80% to 90% of patients of a severe hemorrhagic syndrome, a specific balanced translocation between chromosomes 15 and 17 with a fusion of a large pert of the retinoic acid receptor a gene (RARa) on chromosome 17 to a part of the promyelocytic leukaemia (PML) gene on chromosome 15. More than 75% of patients (under 65 years of age) can be cured, with the application of a combination of anthracyclines and all-trans retinoic acid (ATRA), followed by maintenance therapy.

[Pseudotumor cerebri with all-trans retinoic acid. A case report].

The diagnosis of pseudotumor cerebri (PC) is based on the triad of: (1) papilledema, (2) elevated intracranial pressure with a normal cerebrospinal constituency and (3) normal central nervous system imaging studies. It is an uncommon complication of all-trans-retinoic acid (ATRA) therapy in children treated for acute promyelocytic leukaemia (APL). Its occurrence is rare among adult patients with APL and treated with ATRA .
