RESUMEN
Iron deficiency is a common cause of reactive thrombocytosis resulting in usually mild to moderately increased but sometimes even in extreme thrombocytosis (ie, >1000×109/L). We report a case of a 34-year-old woman who developed an increased platelet count of 1953×109/L. Upon admission, cytoreductive therapy was initiated until an underlying chronic myeloproliferative neoplasia was ruled out. The patient had undergone bariatric surgery 5 years previously, and surprisingly, a diagnosis of reactive thrombocytosis due to iron deficiency secondary to iron malabsorption was made. It is concluded that the degree of extreme thrombocytosis may be even fourfold to fivefold increased in patients with severe iron deficiency. Our finding emphasises the importance of regular control of possible need for iron supplementation following bariatric surgery.

OBJECTIVE: The aim of the study was to examine oral mucosal lesions, microbial changes, and taste disturbances induced by adjuvant chemotherapy (CT) in breast cancer patients during and 1 year after treatment. STUDY DESIGN: Forty-five consecutive breast cancer patients, eligible for adjuvant CT with cyclophosphamide, epirubicin or methotrexate, and 5-fluorouracil were followed before, during, 6 months and 1 year after CT and were compared to a control group of 31 breast cancer patients not receiving adjuvant CT. RESULTS: During CT, oral mucosal lesions developed including erythema (n = 10, 22%) and ulceration (n = 7, 16%). Five patients (11%) were diagnosed with oral candidosis. Scores of dental bacterial plaque and gingival inflammation increased during CT and the oral microbial composition changed towards a more acidophilic flora. Taste disturbances were experienced by 84% (n = 38) of the patients in the CT group. CONCLUSION: In breast cancer patients, moderate-intensive adjuvant CT caused oral mucosal lesions, oral candidosis, taste disturbances and a more acidophilic oral microflora. These adverse effects were temporary and the majority of the patients were mildly affected.
