Outcomes of Overt and Non-overt Disseminated Intravascular Coagulation Using the ISTH DIC Scoring System in Children: A Single-Center Study.

Background: Several disseminated intravascular coagulation (DIC) scoring systems are used for prognosticating the clinical outcomes of patients with DIC. However, research on children is scarce. Therefore, this study compared the clinical outcomes of overt and non-overt DIC using the International Society on Thrombosis and Hemostasis (ISTH) DIC scoring system.

Treatment outcomes of high-dose chemotherapy plus stem cell rescue in high-risk neuroblastoma patients in Thailand.

Background: In 2013, the Thai Pediatric Oncology Group (ThaiPOG) introduced a national protocol in which high-dose chemotherapy plus stem cell rescue is performed without immunotherapy.

Methods: This study aimed to elucidate the outcomes of high-risk neuroblastoma (HR-NB) patients treated with the ThaiPOG protocol. This retrospective cohort review included 48 patients (30 males, 18 females) with a median age of 3 years (range, 8 months to 18 years) who were treated at 5 ThaiPOG treatment centers in Thailand in 2000-2018.

Long-Term Effectiveness, Safety, and Tolerability of Twice-Daily Dosing with Deferasirox in Children with Transfusion-Dependent Thalassemias Unresponsive to Standard Once-Daily Dosing.

Background: Patients with transfusion-dependent thalassemia TDT risk iron overload and require iron chelation therapy. Second-line therapy is warranted for patients demonstrating poor chelation responses.

Patients And Methods: We retrospectively studied the serum-ferritin (SF), and liver-iron-concentration (LIC) outcomes of patients with TDT treated with twice-daily dosing of deferasirox (TDD-DFX) > 24 months, after failing to respond to once-daily deferasirox (OD-DFX).

Antifungal Prophylaxis with Posaconazole versus Fluconazole in Children with Neutropenia Following Allogeneic Hematopoietic Stem Cell Transplantation: Single Center Experience.

Background: Invasive fungal diseases (IFDs) are common and contribute to mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). The relative efficacies of posaconazole (POS) and fluconazole (FLU) as primary antifungal prophylaxes are uncertain.

Methods: A retrospective study was performed on children treated with allogeneic HSCT who received POS or FLU during the early neutropenic period.

Invasive Fungal Diseases in Children with Acute Leukemia and Severe Aplastic Anemia.

Although the outcomes of childhood leukemia and severe aplastic anemia (SAA) have improved, infectious complications are still the major concern. Particularly worrisome are invasive fungal diseases (IFDs), one of the most common causes of infectious-related deaths in patients with prolonged neutropenia. A retrospective study was conducted of IFDs in pediatric patients with newly diagnosed or relapsed acute leukemia, or with SAA, at Siriraj Hospital, Mahidol University, Thailand.

Clinical outcomes and prognosis of Thai retinoblastoma patients.

Background: Retinoblastoma (RB) outcomes in Thailand are unfavorable compared to those of developed countries. This study aims to determine whether the clinical outcomes of patients with RB significantly improved after the implementation of new therapeutic approaches and which clinical factors affect survival and globe-saving outcomes.

Methods: The medical records of patients newly diagnosed with RB and treated at Siriraj Hospital between January 2005 and December 2018 were reviewed retrospectively.

Using of deferasirox and deferoxamine in refractory iron overload thalassemia.

Background: Iron overload is a major complication of transfusion-dependent thalassemia (TDT) and requires iron chelation (IC) therapy. However, a combination therapy may be required for patients responding poorly to monotherapy.

Methods: Nine TDT patients previously treated with IC were enrolled; five patients were previously treated with deferasirox (DFX) twice daily.

Impact of splenectomy on outcomes of hematopoietic stem cell transplantation in pediatric patients with transfusion-dependent thalassemia.

Background: The role of splenectomy prior to hematopoietic stem cell transplantation (HSCT) is controversial. Only few studies compared the outcomes of splenectomized and nonsplenectomized children with transfusion-dependent thalassemia (TDT) undergoing allogeneic HSCTs.

Methods: A retrospective analysis was undertaken on a transplantation cohort of TDT patients; August 1987-December 2014 to compare transplant outcomes between splenectomized and nonsplenectomized groups.

Effect of NUDT15 on incidence of neutropenia in children with acute lymphoblastic leukemia.

Background: 6-Mercaptopurine (6-MP) is considered the backbone of therapy in the maintenance phase of acute lymphoblastic leukemia (ALL). Gene polymorphisms involved in thiopurine degradation are predictors of toxicity in patients treated with 6-MP. We investigated the effects of nucleoside diphosphate linked moiety X (nudix) type motif 15 (NUDT15) polymorphism NUDT15c.

Outcomes of pediatric retinoblastoma treated with ICEV regimen: A single-center study.

Retinoblastoma is the most common intraocular malignancy in children. The aim of this study was to investigate the efficacy and toxicity of combination ifosfamide, carboplatin, etoposide, and vincristine (ICEV) in advanced-stage pediatric retinoblastoma [International Classification of Retinoblastoma (ICRB) group D or E], and in ICRB group C in the second eye in simultaneously treated bilateral retinoblastoma. The medical records of retinoblastoma patients treated with concurrent ICEV regimen and focal therapy were retrospectively reviewed.

Hematologic Malignancies Associated With Mediastinal Germ Cell Tumors: 10 Years' Experience at Thailand's National Pediatric Tertiary Referral Center.

Mediastinal germ cell tumor (MGCT), which accounts for 1% to 3% of extragonadal germ cell tumors, has unique manifestations; it is associated with several types of hematologic malignancy, particularly myeloid neoplasm. The aim of this study was to report the 10-year incidence, clinical characteristics, and outcomes of MGCT at Thailand's national pediatric tertiary referral center. This retrospective study included patients diagnosed with MGCT at the Department of Pediatrics, Siriraj Hospital during 2005 to 2014.

Bisphosphonate Therapy for Refractory Langerhans Cell Histiocytosis: A Case Report.

Although patients diagnosed as Langerhans cell histiocytosis (LCH) with bone lesion initially respond well to treatment, some may experience relapse or refractory disease. Pamidronate, a potent N-bisphosphonate, has been used in several primary bone diseases, benign bone tumors, and metastatic bone cancers. The mechanism includes an inhibitory effect on osteoclast activity by decreasing development and recruitment of osteoclast progenitors and promoting osteoclast apoptosis.

Late effects in survivors of childhood acute lymphoblastic leukemia: a study from Thai Pediatric Oncology Group.

Survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of long-term late effects. Therefore, systematic screenings of the late complications are essential. The objective of this study was to determine the prevalence of late effects of Thai children and adolescents after completion of ALL therapy.

Evaluation of guideline for treatment of febrile neutropenia in pediatric cancer at Siriraj Hospital.

Background: Febrile neutropenia (FN) is a common and important clinical problem in pediatric cancer. Our Institution has developed a clinical practice guideline (CPG) for treatment of FN to assist the clinicians taking care of these patients.

Objective: To evaluate characteristics of FN, sources and causative agents of infection, applicability and effectiveness of the CPG, and factors that associated with response to treatment.

Dengue hemorrhagic fever in patients with thalassemia.

Dengue hemorrhagic fever (DHF) causing by dengue viral infection is endemic in Thailand and Southeast Asian countries where thalassemias are prevalent. Thalassemic patients are also at risk to acquire dengue viral infections and to develop DHF. However, they can have different clinical manifestations and complications as well as more severity than general population requiring special awareness for proper diagnosis and management.
