Complete Resolution of a Case of TAFRO Syndrome Accompanied by Mediastinal Panniculitis,Adrenal Lesion,and Liver Damage with Hyperbilirubinemia

TAFRO syndrome is a systemic inflammatory, lymphoproliferative disorder, but the pathophysiology of the disease is unknown. It is typically characterized by thrombocytopenia, anasarca, a fever, reticulin fibrosis, renal dysfunction, and organomegaly. However, other manifestations have been also reported. We encountered a 43-year-old man with TAFRO syndrome who showed mediastinal panniculitis, liver damage, and adrenal lesions in addition to the core signs. He achieved complete remission with combination therapy of corticosteroids, tocilizumab, and cyclosporin, and remission was maintained even after drug discontinuation at 15 months. Atypical manifestations and complete remission of TAFRO syndrome were remarkable features of our case.     

Acute Myeloid Leukemia Developing with Acute Pancreatitis Mimicking Autoimmune Pancreatitis

A 33-year-old man was admitted to our hospital for fever and abdominal pain. A blood analysis revealed pancytopenia and increased serum pancreatic enzymes with disseminated intravascular coagulation. A detailed examination revealed acute pancreatitis, with diffuse swelling of the pancreas and diffuse beaded dilatation of the main pancreatic duct, which mimicked autoimmune pancreatitis complicated by acute myeloid leukemia. Systemic cytotoxic chemotherapy led to the remission of leukemia and pancreatitis. We hypothesized that the etiology of acute pancreatitis was invasion of leukemia cells. Acute pancreatitis is rare as a symptom of leukemia; however, we should consider the possibility of leukemia during the differential diagnosis of acute pancreatitis.

Successful embolization for uterine hemorrhage in a patient with acute promyelocytic leukemia

A successful embolization for life-threatening uterine hemorrhage is described in a patient with acute promyelocytic leukemia and disseminated intravascular coagulation. On admission the patient was in the 6th week of gestation with incomplete abortion and uterine hemorrhage. In addition to combination chemotherapy and anticoagulant therapy, dilatation and curettage were also performed. After the operation the uterine hemorrhage was progressively increased in amount and was not responsive to usual measures. Embolization of bilateral uterine arteries using Gelfoam was performed with a dramatic improvement of the hemorrhage.     

A pitfall in analyses of relevant factors concerning phenomena in the process of initiating dialysis: alterations in the characteristics of subjects diminish the significance of age

In our previous studies, relevant factors concerning the main phenomena related to the process of initiating dialysis were examined in elderly patients with chronic renal failure. Examined phenomena were as follows: (1) the acceptance of dialysis; (2) the urgency of initiating dialysis; (3) short-term outcome; (4) returning home. Multivariate logistic regression analysis was used to determine relevant factors. Although we speculated that age should be a relevant factor for each phenomenon, the phenomenon on which age had some impact was only the first. We suspected the existence of a pitfall, through which the relation of age was lost in the second, the third, or the fourth phenomenon. The fact that every phenomenon had its own relevant factors was thought to be an important clue to the discovery of pitfalls. Relevant factors were derived from both the number of dropout-patients and their demographic and clinical status. From the viewpoint of nondropout-patients, the progression of the process of initiating dialysis might alter the characteristics of subjects for successive phenomena In this study, we set out to investigate whether alterations in the characteristics of subjects were pitfalls. Alterations were regarded as a fall of the mean age, an increment of the rate of the patients with ability to walk, and an increment of the rate of the patients with normal cognitive function. In addition, the old-old patients tended to have limited numbers of those who had the ability to walk and normal cognitive function. In other words, aging changes in ambulatory and cognitive function were not brought to subjects. These alterations may cause the loss of the relation of age to each phenomenon. Thus, we presumed these alterations to be pitfalls. We must clarify whether aging changes are brought to subjects beforehand in analyses that include the old-old patients as subjects.     

Pulmonary granulomatous lesion with severe chest pain and hemoptysis: a case report]

We encountered a rare case of pulmonary granulomatous lesion accompanied with severe chest pain and hemoptysis. A 42-year-old man visited our hospital complaining of hemosputum. A chest radiograph showed a nodular shadow in the left lower lung field. Further examinations including fiberoptic bronchoscopy, bronchoalveolar lavage and transbronchial lung biopsy did not suggest a diagnosis. During the course of his illness, he suffered an episode of severe chest pain which could be controlled only by intravenous morphine chloride (10 mg). The chest radiograph at the time showed a broad infiltration in the left lower lung field. However, the lung perfusion scintigram taken 2 days before demonstrated decreased blood flow in the same field. We waited for the infiltration in the chest radiograph to diminish and then performed partial resection of the left lower lobe, thus terminating both hemosputum and chest pain. Histological examination showed a cavitary lesion in the periphery of the lung, surrounded by large numbers of infiltrating plasma cells and lymphocytes, among which were many hemosiderinladen macrophages. A small amount of mycelium, considered to be Nocardia or fungus, was seen in the cavity wall. These findings may indicate that an infection had contributed to the formation of a hemorrhagic granulomatous lesion, and that this lesion caused chest pain mainly because of the pleuritis and the decrease in the local pulmonary circulation.
