To optimalize the diagnosis of meningeal involvement in ALL we adapted the alkaline-phosphatase-anti-alkaline-phosphatase procedure (APAAP) to be used for cerebrospinal fluid (CSF) examination. The ...study was performed on 19 patients (9 children with leukemia) with CSF hypercellularity. 490 determinations with a panel of 12 monoclonal antibodies were performed. This method was convenient, cell morphology was preserved so that combined morphological and immunological characterization of specific cells was possible in mixed cell populations. The combined study of immunological and morphological criteria produced more accurate results than those based on morphological criteria alone. The APAAP technique is useful for small numbers of cells. The preservation of antigenic reactivity in frozen CSF smears may be of use in reevaluation studies.
We present a clinical description of a 13-year-old girl with lateral cervical cyst. We particularly emphasize the need for ultrasonographic examination during routine diagnostics of so-called ...cervical tumors.
Acute renal insufficiency in children with malignant lymphoma may be the first symptom of illness. Intensive care with hemodialysis is the therapy of choice. It allows to eliminate the increased ...volume of liquid, toxins, continuing diagnostic and beginning chemotherapy. We present two children with NHL, who showed acute renal insufficiency. Intensive care with hemodialysis was required to treat renal failure before establishing diagnosis and during initial chemotherapy.
Fanconi anaemia (FA) is a rare autosomal recessive disorder. Manifestation of the disease is pleomorphic and may include many congenital malformations and marrow aplasia. Congenital disorders ...include: skeletal abnormalities, hypo- or hyperpigmentation of the skin, renal or heart anomalies and many others. FA is an invariably fatal disease owing to progressive marrow aplasia or the development of acute leukaemia or squamous cell carcinoma. We present two children with Fanconi anaemia who developed acute lymphoblastic leukaemia in the 4 and 12 year of life.
Tumor lysis syndrome is characterized by hyperuricemia, hyperkalemia and hyperphosphatemia followed by hypocalcemia. Sometimes they are accompanied by hyperglycemia. It can lead to acute renal ...insufficiency, neurological and cardiological disorders. In the Clinic of Paediatric Haematology and Chemotherapy in Zabrze, in the period from Jan.01, 1990 to Dec.31, 1997, 305 children were treated due to neoplastic diseases of haematopoietic system: 169 with ALL, 34--ANLL, 48--NHL and 54--HD. Tumor lysis syndrome was found in 11 children, what was 3.6% of all patients. They included 3 children with ALL/1 from group SRG and 2 with HRG/, 2 with ANLL, 6 with NHL/2 with NB-NHL and 4 with B-NHL/. Tumor lysis syndrome did not occur in any patient with HD. Two symptoms of tumor lysis syndrome were found in 13 children (4.26%) including 3 with ALL (1 SRG and 2 HRG), 2 with ANLL and 8 NHL/3-NB-NHL and 5-B-NHL/. Diabetes occurred in two children with ALL. Acute renal insufficiency occurred in 6 children with ALL, 2 with ANLL and 8 with NHL. Two patients with B-NHL required dialysis. One renal insufficiency treated with hemodialyses was the first symptom of lymphoma. To prevent the consequences of tumor lysis syndrome hydration with alkalization, constant monitoring of the above mentioned biochemical parameters are necessary. Acute renal insufficiency, not responding to conservative treatment, should be immediately treated with hemodialyses and chemotherapy should be introduced under its 'shield'.
The aim of study was cochlear function estimation by means otoacoustic emission in children treated by leukaemia cytostatic drugs in course of the bone marrow proliferative diseases. The children ...after treatment of acute lymphoblastic leukemia or nongranulomatic malignant lymphoma according to BFM programme were examined in this study. Audiologic examination of children included tonal audiometry, tympanometry and otoacoustic emission as well. The results were compared to the findings of control group consisted of healthy children have never suffered from ear diseases and have never used ototoxic drugs. No significant differences in tonal audiometry and TEOAE were observed. Aggressive treatment of leukaemia does not result in hearing loss.
