Osteonecrosis of the Jaw After Bisphosphonates Treatment in Patients with Multiple Myeloma.

Background: Bone lytic lesion in Multiple myeloma are the most commonly presented symptoms which require treatment with bisphosphonates (BPs). BPs are providing supportive care, reducing the rate of skeletal morbidity but evidently not abolishing it, the criteria for stopping their administration have to be different from those used for classic antineoplastic drugs, and they should not be stopped when metastatic bone disease is progressing. Osteonecrosis of the jaw (ONJ) has been associated recently with the use of BPs.

Tretatment approach of nontransplant patients with multiple myeloma.

Multiple myeloma is still an incurable disease with pattern of regression and remission followed by multiple relapses raising from the residual myeloma cells surviving even in the patients who achieve complete clinical response to treatment. In recent years there is a huge improvement in treatment of patients with multiple myeloma. The milestones of these improvement are: autologous transplantation and high-dose melphalan, imunomodulating drugs (thalidomide, lenalidomide), proteosom inhibitors (bortesomib, carfilzomib).

Influence of Prognostic Factors on OverallSurvival in Myelodysplastic Syndromes.

Background: Accurate prediction of a patient's prognosis is useful to define the risk posed by the disease. Age, gender, peripheral blood cytopenia, proportion of bone marrow (BM) blasts, performance status, comorbidities, transfusion dependence, specific karyotype abnormalities and molecular biomarkers can refine the prediction of prognosis in MDS.

Aim: to assess the influence of the some prognostic factors like age, gender, cytopenia, BM blast percentage, transfusion dependence, ferritin, hemoglobin (Hb), lactate dehydrogenase (LDH), albumin and specific karyotype abnormalities in myelodysplastic syndromes on overall survival (OS).

Adverse effects of thalidomide administration, in patients with myeloma multiplex?

Introduction: Myeloma multiplex is defined by the presence of monoclonal plasma cell population in the bone marrow>10%,M protein in the serum and/or urine ,and clinical evidence of end organ damage like hypercalcemia ,renal failure, anemia, or bone lesions. In the most hematologic malignancies the role of induction treatment is to achieve complete remission (CR). Thalidomide became a new therapeutic approach but use of Thalidomide as a single agent or combination with steroids or chemotherapy is associated with several side effects like deep vein thrombosis (DVT), peripheral neuropathy (PN), constipation, somnolence, pyrexia, pain, fatigue osteonecrosis of jaw, and teratogenicity that is the most worrying adverse event.

Diagnostic value of brush border enzymes of the proximal renal tubules in rheumatoid arthritis.

Background: Proximal tubules of the kidney have a dominant function in the excretion of different enzymes in the urine. These enzymes can be used as markers for secondary renal damage under the action of different diseases, medicines, and toxins. The aim of this study was to evaluate the values of alanine aminopeptidase (AAP), gamma-glutamyl transferase (gamma-GT), and beta2 microglobulin (beta2m) in urine of patients with untreated rheumatoid arthritis (RA) and to define the possible association between untreated rheumatoid arthritis and tubular function at the brush border region.

Hairy cell leukemia treatment: where we are now?

Hairy cell leukemia (HCL) is a very rare type of leukemia, in which abnormal B lymphocytes, present in the bone marrow, spleen, and peripheral blood stream, get worse slowly or do not get worse at all. HCL is the disease where patients have pancytopenia with splenomegalia over 90% percent, palpable lymphadenopathy occur in 35% of patients, some form of serious infection eventually developed in over 50% of patients and was the most common cause of death in patients. HCL is dominantly a male disease, with the male-female ratio, ranging from 4:1 to 7:1.
