Abstract
Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 10⁹/L, hemoglobin 8.7 g/dL and platelet count 197 × 10⁹/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

Abstract
The aim of this study was to evaluate the relationship between cerebrospinal fluid (CSF) osteopontin (OPN) levels and central nervous system (CNS) involvement in children with a diagnosis of acute leukemia. The study sample consisted of 62 patients who had been diagnosed with acute leukemia. The control group consisted of 16 patients that had presented and had no malignant disease, CNS infection or chronic disease. CSF OPN levels were studied with enzyme-linked immunosorbent assay (ELISA) method. The mean CSF OPN level was 32.76±49.22 ng/ml in the patients at the time of diagnosis and 14.93±6.84 ng/ml in the control group (p>0.05). The mean CSF OPN level was 27.68±32.73 ng/ml at the time of diagnosis in the group without CNS involvement and 53.48±89.21 ng/ml in the group with CNS involvement (p>0.05). However, the CSF OPN level at the time of CNS relapse in patients who developed CNS involvement during follow-up (127.4±52 ng/ml) was significantly higher than in the group without CNS involvement at diagnosis and follow-up (mean CSF OPN level: 27.68±32.73 ng/ml) (p<0.001). The analysis of CSF OPN levels at the time of diagnosis-before relapse and at the periods of relapse and remission in patients who had CNS involvement at diagnosis and/or follow-up revealed statistically significant differences between the time points (p<0.001). High CSF OPN levels in childhood acute leukemia patients may be used as evidence for CNS involvement, and any increases found in CSF OPN levels may be a preliminary predictor for CNS involvement.

Abstract
Candida krusei is an emerging fungal pathogen found primarily in immunocompromised patients. Intrinsic resistance to fluconazole and decreasing susceptibility to other anti-fungal agents are problematic. When colonization occurs, dissemination may follow rapidly. We present a case of a patient with acute lymphoblastic leukemia who, despite being treated prophylactically with fluconazole, developed disseminated C. krusei.

Abstract
A 23-year old woman with acute biphenotypic leukemia (ABL) complained of chest pain with cough, high fever and hemoptysis during induction chemotherapy, although she had been treated with anti-biotics and micafungin. We made a clinical diagnosis of invasive pulmonary aspergillosis (IPA) based on a consolidation in the right upper lung field on a chest radiograph as well as a high level of serum beta-D-glucan (with no evidence of tuberculosis and candidiasis). We changed her treatment from micafungin to voriconazole. Later, we discovered an air-crescent sign by CT scan that supported the diagnosis of IPA. Following voriconazole treatment, clinical symptoms ceased and abnormal chest shadows improved gradually and concurrently with a recovery of neutrophils. IPA must be considered in immunocompromised patients with pulmonary infiltrates who do not respond to broad-spectrum antibiotics. Serological tests and CT findings can aid in early diagnosis of IPA, which, along with treatment for IPA, will improve clinical outcomes.

Abstract
An isolated foot ulcer developed in a child with newly diagnosed acute mixed lineage leukemia during induction chemotherapy. Despite its clinical resemblance to pyoderma gangrenosum, herpes simplex virus infection was eventually diagnosed on histopathology. Treatment with oral acyclovir was ineffective, but the ulcer healed with intravenous acyclovir followed by oral valaciclovir. Viral infection remains an unusual but important cause of isolated extragenital cutaneous ulceration in the immunocompromised child.

Abstract
Continuous venovenous hemofiltration/hemodiafiltration (CVVH/D) is commonly used to provide renal replacement therapy for critically ill patients who are hemodynamically unstable. Occasionally, the addition of plasmapheresis therapy is necessary for some conditions, including immune-mediated acute renal failure, sepsis, fulminant hepatic failure, and thrombotic thrombocytopenic purpura/hemolytic uremic syndrome. Most tertiary care facilities provide centrifugation plasmapheresis instead of membrane plasmapheresis, because of the requirement for both therapeutic plasma exchange and pheresis of cellular blood products. We report a new technique where centrifugation plasmapheresis and CVVHD (P-CVVHD) are combined and used concurrently. Blood from the patient was concurrently filtered utilizing a Hospal BSM 22 machine with a Multiflow 60 hemofilter and a Cobe Spectra continuous cell separator in a parallel configuration. P-CVVHD is technically possible and can be used for long periods of time with limited risks. There may be advantages to P-CVVHD compared with discontinuous combined CVVH/D and plasmapheresis therapy.

Abstract
A 12-year-old boy had been treated with multiagent chemotherapy for acute mixed lineage leukemia and with intravenous hyperalimentation due to persistent diarrhea and vomiting for 2 months. He suddenly complained of horizontal nystagmus and gait disturbance followed by oculomotor palsy and disorientation within a few days. Blood tests revealed low serum vitamin B1 and high serum pyruvate. Magnetic resonance imaging in T2-weighted axial image revealed a high signal inside the bilateral thalami, mamillary bodies and periaquaductal gray matter. He was diagnosed as Wernicke's encephalopathy and successfully treated with vitamin B1. Careful observation and adequate treatment are emphasized in the management of this preventable and curable disease.

Abstract
PURPOSE Little is known about the characteristic macroscopic and microscopic changes that take place during the progression of oral invasive aspergillosis in immunocompromised patients. The aim of this study was to determine the relationship between the oral and histopathologic findings in these patients. Such a study would aid in understanding the early development of subsequent progression of the disease. PATIENTS AND METHODS Twelve patients with hematologic malignancies who developed invasive oral aspergillosis were studied. The condition was divided into three stages according to the oral findings at the time biopsy procedures were performed. Tissue sections from biopsy specimens were stained with hematoxylin and eosin for histopathologic study and the findings were evaluated in relation to the oral findings. Fungal cultures of biopsy specimens were also performed to confirm the causative organisms. RESULTS The diagnosis of oral aspergillosis was established in terms of both histologic and microbiologic evidence in all 12 patients. In the early stage (three patients), isolated areas of violaceous marginal gingiva consisted of degenerated epithelium and connective tissue infiltrated by fungal hyphae. In the advanced stage (four patients), the violaceous marginal gingiva had become transformed into gray necrotic lesions that extended to the attached gingiva. The necrotic lesions showed ulceration and were covered by a pseudomembrane containing fungal hyphae. At the base of the ulcers, connective tissue was occupied by proliferating fungal hyphae, with vascular invasion being observed. In the late stage (five patients), the ulcerated lesions had progressed, showing destruction of the alveolar bone and surrounding facial muscles, with infiltration of fungal hyphae unto the tissues. No inflammatory cellular reaction was observed until the hematologic status of the patients improved. CONCLUSION These findings indicate that invasive oral aspergillosis has three distinctive clinicopathological stages. Recognition of the different stages of invasive Aspergillus infections is helpful for correct diagnosis of the disease.

Abstract
We report here an uncommon case of neonatal acute leukaemia that presented concomitant with serological evidence of rubella infection. The clinical course was aggressive and the patient died 5 days after diagnosis from septicaemia. Leukaemic blasts had a mixed lineage immunophenotype co-expressing a constellation of B-lymphoid (CD19, cytCD22, TdT) and myeloid (CD13, CD33, CD14, anti-MPO) markers, as well as multiple adhesion molecules and markers associated with early lympho-myeloid progenitor cells (CD34, CD7, HLA-DR). A previously unrecorded discordant expression of different CD10 and CD34 epitopes was identified using different monoclonal antibodies. The karyotype was 46,XX t(4;11)(q21;q23) and molecular analysis confirmed rearrangement of the trithorax-related oncogene HRX at 11q23. There was a clonal biallelic rearrangement of the immunoglobulin heavy-chain gene. The features of this rare case have implications for possible aetiological events leading to leukaemia.

Abstract
Although the great majority of acute leukemias have been designated as being of lymphocytic or myelocytic origin, recent reports have described elements of both in some patients. We describe here the first case of hybrid acute leukemia in an HIV-antibody-positive patient as well as the first hybrid involving B-cell (Burkitt) acute lymphocytic leukemia and acute myelomonocytic leukemia proven by cytochemical, immunologic, and cytogenetic methods. This case illustrates the increasingly complex difficulties in the diagnosis and treatment of AIDS-related malignancies.
