Vein thrombosis is a rare disorder diagnosed in childhood. The principal causes of this illness are inborn thrombophilias, essential thrombocytosis, neoplasms, autoimmunologic diseases and pathologic reaction to certain drugs. Budd-Chiari syndrome, a hepatic vein occlusion is an atypical manifestation of vein thrombosis. Due to the abundant symptomatology, interdisciplinary diagnostic procedures and serious prognosis the Budd-Chiari syndrome is a challenge for contemporary medicine. We present a 16 years old girl with essential thrombocytosis, the complicated by hepatic vein thrombosis.

INTRODUCTION: Bone marrow transplantation from HLA identical family donors is the treatment of choice for children with severe aplastic anaemia (SAA). When there is no donor available, combined immunosuppressive therapy is given. AIM: evaluation of results of immunosupressive therapy in children with severe aplastic anaemia. MATERIAL AND METHODS: SAA was diagnosed in 105 children (42 girls, 73 boys), aged 2-18 years, in the eleven haematological centres in Poland, between 1993-2007. All patients received the Severe Aplastic Anaemia Working Party of the EBMT protocol which included: antilymphocyte globulin or antithymocyte globulin, cyclosporin A, prednisolone. Granulocyto- or granulocytomacrophagic-cell stimulation factor was additionally administered during deep neutropenia. Haematological response was evaluated on day 84 or 112 and 180 of the therapy. RESULTS: complete remission occurred in 53 patients (51.5%), partial remission in 27 (24.7%), no response was obtained in 25 children (23.8%) on day 180, of the therapy. Period of observation was from 12 months to 12.5 years. During this time relapse occurred in 10 patients (9.5%). We observed 22 deaths: 8 early, during the first 3 months of IS and 14 after the first 3 months of immunosuppresive therapy (IS). At present 70 children (66.6%) are in first remission with lasts from 12 months to 12.5 years. The survival at 12.5-years is 78.6%. During the 12.5 years of follow-up we had two cases with a late clonal complication (PNH and MDS). Transformation to acute nonlymphoblastic leukaemia was observed in two of our patients. CONCLUSIONS: 1. Immunosuppresive therapy (IS) in children with SAA, without bone marrow family donors, is more effective after introduction of combined IS (12.5 years survival in this study was 80% for children with very severe aplastic anaemia (v SAA). 2. In our studies among the children followed up after IS therapy, there were: 1 case of periodic nocturnal haemoglobinuria (PNH), 1 case of myelodysplastic syndrome (MDS) and 2 cases of myeloid leukaemia (probability of incidence was 3.8%).

Chronic neutropenia is a decrease in circulating neutrophils in the peripheral blood lasting over 6 months. Values need to be refered with the age and race. In children aged 2 weeks to 12 months reffered values are above 1000/03BCL. There are congenital and aquired reasons of neutropenia in infancy. The most common type of chronic neutropenia in infants is chronic, benign neutropenia (AIN). Authors present ten infants between three and six months with chronic, benign neutropenia. The reason of ordering laboratory tests at outpatient clinic were benign upper respiratory tract infections (four cases), pallor (four cases) and on parental demand (one case). In one infant neutropenia was observed during treatment of pneumonia at a district hospital.

The thalassemias are inherited disorders resulting from deficient synthesis of one or more polypeptide chains of normal haemoglobin. There are two main groups of thalassemia: alpha and more common beta. The carriage of thalassemia genes are widely spread and the disease is considered the most common genetic disorder worldwide. Thalassemias are particularly prevalent in inhabitants of Italy, Greece, Spain, Mediterranean Islands, West Africa and some parts of Asia. The most common thalassemia beta cases are characterized from asymptomatic to severe microcytic anaemia with hepatosplenomegaly and physical development disturbances. The authors present eight unrelated children from the Pomerania Region of Poland complaining of chronic microcytic anaemia with normal iron level. Elevated level of haemoglobin A2 and in some of them haemoglobin F revealed thalassemia beta.

INTRODUCTION: Bone marrow transplantation from HLA identical family donors is the treatment of choice for children with severe aplastic anaemia (SAA). When no donor is available, combined immunosuppressive therapy is given. AIM: Evaluation of results of immunosuppressive therapy in children with severe aplastic anaemia. MATERIAL AND METHODS: SAA was diagnosed in 85 children (31 girls, 54 boys) aged 2-17.5 years in the eleven centres of the Polish Paediatric Leukaemia and Lymphoma Study Group (PPLLSG) in Poland between 1993-2003 years. All patients received protocol of the Severe Aplastic Anaemia Working Party of the Europe Bone Marrow Transplant (EBMT): antilymphocyte globulin or antithymocyte globulin, cyclosporin A, prednisolone and granulocyto- or granulocyto-macrophagic-cell stimulation factor was additionally administered during deep neutropenia. Haematological response was evaluated on day 84, 112 or 180 of the therapy. RESULTS: complete remission occurred in 43 patients (50.5%), partial remission in 22 (25.4%), no response was obtained in 20 children (23.7%) in 180 day of the therapy. Period of observation was from 12 months to 10.5 years. During this time relapse occurred in 6 patients (7%). We observed 16 deaths: 7 early during the first 3 months of immunosuppressive therapy (IS) and 9 after the first 3 months of IS. CONCLUSION: the actual survival at 10-years, after immunosuppressive therapy is 81.2% in our group. Transformation to leukaemia or myelodysplastic syndrome (MDS) was not observed in any of our patients. We observed one case with paroxysmal nocturnal haemoglobinuria (PNH).
