Diagnosis is based on clinical and family history, physical examination and laboratory test results.
Age of onset and severity vary considerably depending on the degree of anemia and hemolysis. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. HS is a very heterogeneous disease caused by an intrinsic defect of red cells; there are other secondary disorders to this affection. Management and treatment Treatment involves management of jaundice phototherapy and even exchange blood transfusion to prevent hyperbilirubinemic encephalopathy and RBC transfusions in case of severe, symptomatic anemia.

The development of new esferocitodis allowed finding out the first biochemical alterations in erythrocyte membrane proteins and later on, the recombinant DNA techniques made possible to detect molecular alternations.
This procedure is recommended for patients with severe hemolytic anemia and moderately asymptomatic individuals who have vesicular lithiasis Palabras clave: Antenatal diagnosis Prenatal diagnosis for at-risk pregnancies is possible if disease-causing mutations have been identified in a family, but it is not routinely performed due to the usually mild disease course.
Hereditary spherocytosis HS is a disease characterized by hemolytic anemia of variable severity, with spherocytes in peripheral blood and a clinical response to splenectomy. Diagnostic methods Diagnosis is based on clinical and family history, physical examination and laboratory test results.
Autosomal recessive inheritance and de novo mutations have also been reported, but are less common. Clinical symptoms such as jaundice, splenomegaly, anemia, aplasia esfeocitosis biliary calculi prompting a diagnosis of HS are in reality rare.
Molecular genetic testing is not routinely used to confirm diagnosis. Pre and post-splenectomy vaccine prophylaxis and prophylactic antibiotics are recommended in order to prevent infections. You can change the settings or obtain more information by clicking here.

The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years.
The journal fully endorses the goals of updating knowledge and facilitating the acquisition of key developments in internal medicine applied to clinical practice. It has been proved that this disease is caused by defects in proteins participating in vertical interactions between membrane skeleton and lipid bi-layer.
Este hecho explica la discrepancia entre estos valores. Splenectomy usually results in disappearance of anemia herwditaria clear amelioration of hemolytic markers.
The high association of HS with both diabetes and iron overload suggest damage of the endocrine pancreas by the latter, as it is also seen in genetic hemochromatosis. Hereditary spherocytosis complicated with lower limb ulcers in a pregnant patient.
SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Four HS categories have been identified: Rare complications include poor growth, skin ulceration, chronic dermatitis, high output heart failure, and secondary iron overload. This explains the discrepancy between these values. Print Send to a friend Export reference Mendeley Statistics. Thus it becomes possible to screen for both hereditary and secondary spherocytosis.
Nine issues are published each year, including mostly originals, reviews and consensus documents.

Prenatal diagnosis for at-risk pregnancies is possible if disease-causing mutations have been identified in a family, but it is not routinely performed due to the usually mild disease course.
Red cell morphology, osmotic resistance, hypertonic cryohemolysis test, eosinmaleimide binding in flow cytometry, sodium dodecyl sulfate-poly acrylamide gel electrophoresis and ektacytometry are all used to diagnose HS.
