Extra translocation +der(1q9p) is a prognostic indicator in myeloproliferative disorders.

An identical extra derivative chromosome resulting from a translocation between the long arm of chromosome 1 and the short arm of chromosome 9, +der(1q9p), has been observed in three patients with a myeloproliferative disorder. Two patients had polycythemia vera in transformation (erythroleukemia in one patient and refractory anemia in the second), whereas the third patient had myelofibrosis which later evolved into acute myelomonocytic leukemia. The two patients who developed overt leukemia did not receive any previous cytotoxic treatment. Non-isotopic in situ hybridization was performed in two patients, allowing for the localization of the breakpoints in 1q12 and 9q12. A similar rearrangement has been previously described in patients with polycythemia vera, either at diagnosis or in advanced stages of the disease. These data suggest that this chromosome abnormality may be consistently associated with myeloproliferative disorders showing a high propensity to transformation, which is not treatment related, and the finding of the +der(1q9p) may represent a poor prognostic sign when observed in the chronic phase.

Distally based venous flap: a new technique for the correction of syndactyly without skin graft in adult patients

Skin grafts and local flaps are conventional methods for repairing simple syndactyly. Skin grafts usually leave unsightly appearance and contracture formation. In this study, unipedicled distally based venous flap were raised from third or fourth metacarpal area of the hand for syndactyly treatment. The distally based venous flap was to provide skin coverage to one side of the finger, in order to avoid complications arising from using skin graft. Nine patients’ syndactylies (5 simple incomplete and 4 simple complete syndactyly) were treated using this method. The mean follow-up period of the flaps was 14 months, ranging from 12 to 16 months. Mild edema and venous congestion occurred in all flaps. Superficial necrosis involving two flaps did not affect flap survival. All flaps survived completely. In this article, we have described a new surgical technique for the correction of syndactyly in a single surgical procedure that utilizes a distally based venous flap to provide skin coverage without skin graft.     

PET/CT findings in a multicentric form of Castleman's disease

We report a case of a multicentric form of Castleman's disease (CD). A thoracic computerized tomography (CT) scan showed multiple mediastinal and bilateral axillary lymph nodes. Fluoro-18 fluoro deoxyglucose ((18)F-FDG) positron emission tomography-PET/CT scan demonstrated increased (18)F-FDG accumulation in multiple lymphatic regions and in bilateral pleural areas. The histopathological sampling of an excised left axillary lymph node revealed a multicentric form of CD, of an intermediate (mixed) cell type. The disease, its differential diagnosis and the diagnostic contribution of nuclear medicine imaging, are described.

Left ventricular pseudoaneurysm developing as a late complication of coronary artery bypass grafting with apicoseptal plication

Left ventricular pseudoaneurysm is a false aneurysm, which results from a left ventricle rupture contained by adherent pericardium or scar tissue. The most common etiology of left ventricular pseudoaneurysm is acute myocardial infarction but one-third of pseudoaneurysms develop following surgery. We present a case report of a patient who developed a false aneurysm of the left ventricle 2 months following surgical repair of a left ventricular aneurysm with a concomitant coronary bypass.     

A rare cause of sudden vision loss in a young male: papillary fibroelastoma of the aortic valve

Cardiac papillary fibroelastoma (CPF) is a rare cardiac neoplasm predominantly affecting the cardiac valves. Although it is most commonly an incidental finding, it can result in life-threatening complications, such as coronary and cerebral embolism, acute valvular dysfunction, and sudden death. In this report, we describe a case of a patient with aortic valve papillary fibroelastoma, which presented with sudden vision loss due to branch retinal artery occlusion. To the best of our knowledge, this is the third case of CPF-related retinal artery embolism in English literature.
