ABSTRACT
We report successful treatment of a refractory myelodysplastic syndrome-associated pyoderma gangrenosum with the combination of thalidomide and interferon-alpha2a in a single patient. A non-healing wound developed on a 40-year-old woman's left thumb after minor trauma. Massive ulcerovegetative lesions developed after reconstruction surgery. Histopathological examination of the bone marrow and cytogenetic studies revealed an atypical myeloproliferative/myelodysplastic syndrome. The skin lesions resolved dramatically after two months of thalidomide and interferon-alpha2a combination therapy and the haematological status improved.

BACKGROUND AND AIM: Patients with acute leukaemia suffer from various haemorrhages, most frequently due to thrombocytopenia. We could not reach any information regarding the frequency of gastrointestinal bleeding in acute leukaemia and decided to search this complication in patients with acute and chronic leukaemias and myeloproliferative disorders, retrospectively. PATIENTS AND METHODS: During a 6-year period, 291 patients with acute leukaemia, 52 patients with chronic leukaemia and 108 patients with myeloproliferative disorders had been followed. Thirty-two cases of overt gastrointestinal haemorrhage episodes (25 upper, 7 lower) were observed during the mentioned period. RESULTS: The frequency of bleeding episodes was 7.1% (32/451) in haematologic malignancies as a whole, 5.8% (17/291) for acute leukaemia, 1.9% (1/52) for chronic leukaemia and 13% (14/108) for myeloproliferative disorders. If the patients with myeloproliferative disorders in blastic phase were analysed separately, the ratio was 30% (6/20). Oesophagogastroduodenoscopy, which could be performed in 8 of 25 upper gastrointestinal haemorrhage episodes, revealed erosive gastritis in five patients and duodenal ulcers in three patients. Neutropenic enterocolitis was the underlying cause in all of the seven patients with lower gastrointestinal haemorhage. Five out of the seven patients had acute leukaemia. In 7 bleeding attacks, out of 32, the ultimate result was death. Generally, the haemorrhage was only a contributing cause of mortality. All of the mortality cases were patients with acute leukaemia. CONCLUSION: Especially, the patients with myeloproliferative disorders are prone to develop gastrointestinal haemorrhage. The manifestation is generally as upper gastrointestinal bleeding due to gastric erosions and duodenal ulcers. Lower gastrointestinal bleeding is frequently a problem of the patients with acute leukaemia. It is commonly a sign of neutropenic enterocolitis.

The present study describes the characteristics and clinical management of two patients with ectodermal dysplasia with long term follow-up. Dental treatments depend on the severity of disorder, therefore, treatment varies according to the age, growth and development of the stomatognathic system of the patient. It is important that the patient and dentist understand continued monitoring for dental problems is necessary. This provides improved aesthetics, function and emotional development.
