This study aims to determine the frequency and identify the factors associated with undernutrition among patients undergoing visceral surgery in 2014. We conducted a cross-sectional, descriptive and analytical study over the period September 11, 2014-December 11, 2014. The study population comprised patients who had undergone visceral surgery at the National University Hospital Centre Koutoucou Hubert MAGA, Cotonou. Undernutrition is defined as a body mass index less than 18.5 kg/m2 . A total of 90 patients were included in the study, 57,78% (52 patients) were male...

OBJECTIVES: Acute myeloid leukemia (AML) with hyperleukocytosis (HL) is intuitively thought as a unique group with dismal prognosis. However, comprehensive studies regarding the genetic landscape and clinical outcome in this group of patients are limited. METHODS: 693 newly diagnosed de novo non-M3 AML patients were consecutively enrolled. We compared relevant mutations in 20 genes between AML patients with or without HL and exposed their prognostic implications...

Data about malignant blood diseases are sparse in Cameroon. Their epidemiology was studied in patients at the General Hospital of Douala (GHD) and the Yaoundé Central Hospital (CHY) from 2004 through 2014. The variables we studied were social and demographic (age, sex, occupation, marital status), clinical (reasons for consultation, clinical signs, year of diagnosis), and biological (blood count, myelogram and blood smear, immunophenotyping, biopsy, and cytogenetics). In all, 4409 files were reviewed and 454 cases identified, documented and confirmed (248 in GHD and 206 in CHY)...

Hyperleukocytosis is defined as a white blood cell count greater than 100.000/μL in patients affected by acute or chronic leukemias. Hyperleukocytosis is more common in acute leukemias than in chronic leukemias. Risk factors include younger age, acute myeloid leukemia, the microgranular variant of acute promyelocytic leukemia, acute lymphoblastic leukemia and some cytogenetic abnormalities. Although it can affect any organ system, symptoms usually arise from involvement of the cerebral, pulmonary and renal microvasculature...

Hyperleukocytosis occurs in 15-20% of all newly diagnosed acute myeloid leukemia patients and requires emergent treatment with leukapheresis or hydroxyurea when accompanied by signs or symptoms of leukostasis. Currently, there is no standardized hydroxyurea dosing strategy, although usual dosing ranges from 50 to 150 mg/kg/day, and prescribing patterns vary significantly among oncologists and institutions. In addition to other hematologic and dermatologic toxicities, the use of hydroxyurea may be associated with significant mucositis and mucositis-related pain...

REVIEW
Anand Padmanabhan
Cellular collection is an important and increasingly used apheresis procedure. These collections are performed by leukocytapheresis, a procedure involving the removal of a patient's or donor's white blood cells, and are used to collect hematopoietic progenitor cells, specific cell populations (such as T-lymphocytes), and granulocytes. Hematopoietic progenitor cell apheresis and T-lymphocyte collection are performed by procedures that enrich for mononuclear cells. Hematopoietic progenitor cells are used for autologous and allogeneic hematopoietic stem cell transplantation, whereas T-cell collection is being used increasingly in novel cellular therapy approaches and for donor lymphocyte infusions to induce graft-versus-leukemia effect...

BACKGROUND: Hyperleukocytosis is a serious, life-threatening complication of pediatric acute leukemia that can cause neurologic injury, pulmonary leukostasis, metabolic derangements, and coagulopathy. Acute leukemia has the highest risk of mortality and morbidity at presentation when associated with hyperleukocytosis. Infant leukemia presents unique challenges and treatment considerations due to the disease itself and size and overall health of the patient. While medical management of hyperleukocytosis in older patients with acute leukemia has been described, including cytoreductive procedures with automated leukapheresis (AL) or manual whole blood (WB) exchange transfusion, very little data exist for standardized management of hyperleukocytosis in infant leukemia patients...

BACKGROUND AND OBJECTIVE: Pulmonary embolism is potentially life-threatening in patients with lung cancer, but the clinical studies on patients with lung cancer having asymptomatic pulmonary embolism were barely reported. METHODS: Clinical data of patients with lung cancer were obtained from the Department of Respiratory and Critical Care Medicine of Tianjin Chest Hospital during July 2012 and June 2015 and were reviewed retrospectively. A total of 28 patients with lung cancer having pulmonary embolism (LP group) were enrolled, and another 56 cases with lung cancer alone (LC group) were enrolled as controls...

We report the outcome of 27 children with de novo acute megakaryoblastic leukemia (AMKL) (excluding Down syndrome) enrolled in the French multicenter prospective study ELAM02 (2005-2011). There was no difference in gender, initial leukocyte count, CNS involvement, and complete remission rate (88.9%), as compared to other acute myeloid leukemia (AML) subtypes. AMKL patients had a significantly poorer outcome (5-year overall survival 54% [CI 95% 33%-71%] than children with other AML subtypes (5-year overall survival 73% [CI 95% 68%-77%] p = 0...

BACKGROUND/OBJECTIVES: Childhood acute myeloid leukemia (AML) is a rare and heterogeneous disease. Pediatric data on the epidemiology of acute kidney injury (AKI) in AML are limited. We report on the incidence of AKI in childhood AML and the risk factors associated with AKI episodes. METHODS: A retrospective cohort of 53 patients (≤18 years), with de novo AML, receiving chemotherapy over a 10-year period. All serum creatinine (SCr) levels during therapy-related hospitalizations were assessed to stage AKI episodes as per Kidney Disease: Improving Global Outcomes criteria...

BACKGROUND: Chronic myeloid leukemia (CML) is a common hematologic malignancy; however, its occurrence during pregnancy is unusual due to its low prevalence in females of childbearing age. There are conflicting reports of how to best manage CML in pregnancy, particularly in the setting of leukocytosis. HEMAPHERESIS: A 30-year-old female was diagnosed with CML at 18 weeks' estimated gestational age. On initial presentation she reported fatigue, night sweats, and early satiety, and was found to have a white blood cell (WBC) count of 69...

A 16-year-old boy was incidentally found to have hyperleukocytosis during a school physical examination. He was diagnosed with atypical chronic myeloid leukemia in chronic phase. Although treatment with hydoxyurea was started, his white blood cell count increased and he eventually developed lethal intracranial hemorrhage. Although very rare, intracranial hemorrhage should be considered as a possible complication in patients with atypical chronic myeloid leukemia, even in chronic phase, if they have hyperleukocytosis and thrombocytopenia...

Acute lymphoblastic leukemia is the most common (77%) childhood leukemia and also the most common neoplastic disease in children. Acute lymphoblastic leukemia initially present with hyperleukocytosis (WBC count more than 50,000/mm³) in twenty percent cases. These children are particularly at risk of development of tumor lysis syndrome (TLS). Tumor lysis syndrome is a metabolic disorder consists of hyperuricaemia, hyperkalemia, hyperphosphataemia, hypocalcaemia with or without renal insufficiency. It is the most common disease related emergency encountered by physicians caring for cancer of children and adult...

Esophageal stricture is a major secondary complication of ingesting caustic agents. We examined our experiences with caustic injuries with a view to finding clinical and biological risk factors of esophageal strictures secondary to caustic ingestion. Records were retrieved for 58 adults admitted consecutively to our intensive care unit for caustic ingestion. Fifty cases were managed conservatively and therefore retained for analyses. Patients were grouped according to whether they developed strictures or not during the follow-up period...

BACKGROUND: Hyperleukocytosis, defined as white blood cell (WBC) count above 100 × 109 /L, has high early morbidity and mortality from leukostasis-related complications, namely intracranial hemorrhage and pulmonary distress. Initiating chemotherapy without prior leukocytoreduction may lead to tumor lysis syndrome (TLS). Therapeutic leukocytapheresis (TL) is used as one leukocytoreductive intervention; however, its safety and efficacy in pediatric leukemia has not been established. The purpose of this study is to evaluate safety of TL in pediatric patients and assess the efficacy of TL in reducing WBC count in pediatric leukemia...

The application of apheresis equipment to perform leukapheresis (LK) in low weight paediatric patients is logistically complex and lacking of largest clinical performing experiences, meanwhile, the benefit from LK is controversial. In this study, 15 children with acute lymphoblastic leukemia(ALL)and acute myeloid leukemia (AML) and hyperleukocytosis were treated with the COBE Spectra apheresis system in the general paediatric ward by the staff from the department of Blood Transfusion. 26 LK procedures were performed...
