A 55-year-old man was admitted to our hospital for the evaluation of neutropenia. On physical examination, he had apthae and splenomegaly. CBC showed 1,000/microliter WBC with 5% neutrophils, and microcytic anemia consistent with iron deficiency. Bone marrow examination revealed a marked decrease of mature neutrophils, but normal percentage of immature myeloid cells. There was no morphological abnormality in the hemopoietic cells. He had no drug or family history responsible for the neutropenia. Anti-neutrophil auto-antibody was negative. Hence, a diagnosis of chronic idiopathic neutropenia (CIN) was made. He developed frequent episodes of infection such as balanitis, peri-anal infection, gingivitis, and pharyngitis. He was treated with steroid pulse therapy, anabolic hormone, and high dose gamma-globulin infusion, but no significant improvement occurred. Then, recombinant granulocyte-colony stimulating factor (rG-CSF) was started. The neutrophil count was normalized by the 7th day of 5 micrograms/kg/day rG-CSF administration. The administration of G-CSF was discontinued after a 14-day course. Thereafter, the neutrophil count remained at near normal level (approximately 1,500/microliter) and there have been no episodes of infection in the last 5 months. However this cannot be explained simply by the direct effect of rG-CSF on the myeloid precursors; rather, it suggests some unknown effect of G-CSF on the bone marrow microenvironment regulating myeloid hemopoiesis. We consider this to be a rare case of CIN with frequent episodes of infection, which was successfully treated with G-CSF.

Thalassemia is a genetic disorder that involves abnormal haemoglobin formation. The two main categories of thalassemia are alpha and beta thalassemia that are then divided into further subcategories. While some mild forms of thalassemia might even go unnoticed and only cause mild anaemia and iron deficiency problems in patients, other more severe forms of thalassemia can even result in death. Individuals with thalassemia can get treatment according to the level of severity of their condition. The main oral manifestations of thalassemia are Class II malocclusion, maxillary protrusion, high caries index, severe gingivitis. Any dental surgical procedure for such patients should be done under antibiotic cover and immediately after transfusion. Caution should be exercised in thalassemia patients due to complications related to compromised immunity and cardiovascular issues. Multidisciplinary approach involving dental surgeon, haematologist and orthodontist is the best advised approach.
