    Chromosome 12;15 rearrangements in patients with recurrent miscarriage.
    (2006-09) Nair, S B; Mukundan, G; Paul, B M; Ramachandran, L; Gopinathan, K K; Joseph, Sajayan
    Background: An abnormal karyotype in either partner, especially featuring a translocation and/or inversion is considered to be a cause of recurrent miscarriages. It is generally assumed that recurrent miscarriage might be due to recurrent chromosomal abnormalities in the fetus due to a balanced aberration in one of the parents being inherited by the offspring in an unbalanced form. Aim: Evaluation of chromosomal rearrangements in couples with recurrent miscarriages. Materials and Methods: Peripheral blood was collected and lymphocyte cultures were set up. Slides prepared from the cell suspension were stained and screened for metaphases followed by karyotyping. Result: Balanced translocation was observed in the male partner in one case and in the female partners in the three other cases. Conclusion: Couples with recurrent miscarriage should be investigated for chromosomal rearrangements, thus helping in genetic counseling and providing the options for future pregnancies.

    Glanzmann's thrombasthenia.
    (2001-06-14) Tullu, M S; Dixit, P S; Nair, S B; Kamat, J R; Vaswani, R K; Shetty, S D; Pawar, A R
    Glanzmann's thrombasthenia (GT) is an uncommon cause of bleeding in children. We diagnosed two siblings as having GT on the basis of flow cytometric studies. Both had cutaneous bleedings and epistaxis since early childhood. Hematological investigations revealed prolonged bleeding time and a normal platelet count. Both the patients had absence of aggregation of platelets with the agonist adenosine diphosphate. Absence of the GPIIb/IIIa receptor was confirmed by flow cytometry. A short review of the disorder is presented.
