ABSTRACT
Background: As a new point, some very rare features can be revealed as initial diagnosis of acute lymphoblastic leukemia (ALL) without any evidence of lymphoma-like behavior which after initial recovery, presents with new evidence of lymphoma. Herein, a case of the immunophenotypes of blast cells in B-cell precursor acute lymphoblastic leukemia originated from MYC gene-related that was evidenced later by burkitt lymphoma feature. Case Presentation: Our case was initially diagnosed as a typical B-cell ALL cells with L1 morphology in peripheral blood smear and bone marrow aspiration that was not recovered and referred again that was finally featured as burkitt's lymphoma with L3 morphological feature. Conclusion: Thus, in the primary diagnosis of B-cell ALL and especially in cases with treatment failure, the final feature of burkitt's lymphoma should be potentially in mind.
ABSTRACT
Background: Thalassemia is the most common inherited anemia in worldwide. Heart failure is the most common cause of mortality and morbidity in patients with major and intermedia ß-thalassemia. This study aimed to evaluate the effect of oral administration of L-arginine on the improvement of systolic Pulmonary Artery Pressure (PAP) and cardiac function in patients with major and intermedia ß-thalassemia. Methods: This randomized clinical trial was done on 88 patients with ß-thalassemia admitted to Ali Asghar Hospital, Tehran, Iran between 2020 and 2021. Echocardiography was performed for all the patients before the intervention. Afterwards, the patients were randomly divided into two groups of placebo and L-arginine. The patients underwent echocardiography after eight weeks and were compared with respect to the results. Results: The mean blood transfusion interval was 20.21 d in the placebo group and 17.14 d in the L-arginine group (P=0.082). The results revealed no significant difference between the two groups regarding the mean levels of Hemoglobin (Hb) and ferritin, frequency of splenectomy. However, the mean PAP significantly decreased from 32.88 to 26.02 in the L-arginine group (P=0.009), but did not change in the placebo group. Nonetheless, no significant change was observed in the mean Ejection Fraction (EF) before and after L-arginine administration. Conclusion: L-arginine administration prevented the increase of PAP and was effective in preventing cardiovascular disorders including increased systolic PAP in patients with major and intermedia B-thalassemia. However, the results have to be confirmed in further studies with larger sample sizes.
ABSTRACT
Background: Glucocerebrosidase (GBA) mutation is the most common genetic risk factor in Parkinson's disease (PD). Transcranial sonography (TCS) shows increased substantia nigra (SN) echogenicity in both idiopathic and genetic forms of PD. The goal of this study was to compare maximal area of SN hyperechogenicity (aSNmax) and diameter of third ventricle (DTV) between GBA mutation carriers and healthy controls. Methods: Twenty-six carriers of GBA mutation and twenty-six healthy controls underwent TCS. The aSNmax and the DTV were measured. Mini-mental status examination (MMSE) and demographic data of the subjects were recorded, too. Results: Mean aSNmax in GBA mutation carriers was significantly higher (0.31 ± 0.06 cm2) than controls (0.16 ± 0.04 cm2). Moreover, DTV was significantly higher in GBA mutation carriers group (3.98 ± 0.90 vs 3.29 ± 0.56 cm). Conclusion: Increased SN echogenicity and increased third ventricle diameter in GBA mutation carriers may be caused by alterations in iron metabolism with reference to their genetic status.
ABSTRACT
BACKGROUND: Researches mainly focus on patients who suffer from cancer. Families and parents have been neglected in these researches although they experience levels of stress, depression and anxiety. This research aims at studying the effectiveness of Hope Therapy based on group therapy on hope and depression of mothers with children suffering from cancer in Aliasghar Children's Hospital, Tehran (2010). METHODS: In this applied and semi-experimental research, 20 mothers were selected based on Snyder Hope Scale and Beck Depression Inventory (pre-test). They were randomly assigned into two groups of experimental and control. Intervention based on Hope Therapy protocol was executed on the experimental group for eight weeks (eight sessions, each lasted for 2 hours). Afterwards, post-test was performed for both groups. After eight weeks, the experimental group completed questionnaires and the follow up phase. RESULTS: Results demonstrated that Hope Therapy increases hope (p<0.05), and decreases depression in mothers of children with cancer (p<0.001). CONCLUSION: Covariance analysis indicated that Hope Therapy significantly decreases depression and increases hope of mothers whose children suffer from cancer. Follow up results showed no significant changes in hope of this group of mothers in the two months after post-test, but depression was decreased significantly during this period. It was concluded that effectiveness of Hope Therapy may be continued during the follow up phase.
