A 73-year-old female patient with myelomatous pleural effusions is described. She was admitted to our hospital with lumbago and emaciation. Laboratory findings revealed cytopenia and hypogammaglobulinemia. Immunoelectrophoresis demonstrated Bence-Jones monoclonal protein in the serum, but not in the urine. Bence-Jones myeloma was diagnosed by the bone marrow aspiration. Chest X-ray film, however, showed bilateral pleural effusions. Fluid cytology revealed numerous immature plasma cells, indicating pleural involvement. Intrapleural administration of alpha-interferon combined with systemic chemotherapy (oral melphalan-prednisolone with alpha-interferon im.) was successful in maintaining the resolution of pleural effusions. Intrapleural alpha-interferon administration seems to be effective in the management of myelomatous pleural effusions.

A diagnosis of plasma cell myeloma was made in a 6-year-old Holstein cow that showed continuous nosebleed, progressing emaciation, and hyperglobulinemia. Necropsy revealed enlargement of the caudal mesenteric lymph nodes. Lymph nodes and spleen were infiltrated by neoplastic plasma cells. Renal lymph nodes, bone marrow, and kidneys also were affected. Amyloid-like material that was negative for Congo red was present in most of the affected lymph nodes. Congo red-positive amyloid material was noted in spleen, kidneys, liver, and adrenal glands. Neoplastic plasma cells exhibited immunohistochemical reactions for lambda-light chain and 3 classes of heavy chain but not for kappa-light chain. Nonamyloid deposits were labeled with antisera against lambda-light chain and heavy chains. Plasmacytoid cells, which stained positively for IgG, IgM, or IgA, were intermingled in all lesions. Production of 3 types of immunoglobulins may be caused by heavy-chain class switching, constantly occurring in certain proportions.

An elderly woman diagnosed with multiple myeloma (MM) in 2007 had improved with chemotherapy. She had severe kyphosis and a diaphragmatic hernia (DH), but no respiratory symptoms. In 2011, because of thoracic deformity and emaciation, we advised her to continue the previously prescribed domiciliary noninvasive positive pressure ventilation (NPPV) therapy for chronic type II respiratory failure. However, she refused to continue NPPV. She was later admitted for deterioration in respiratory status and carbon dioxide (CO2) narcosis. We believed her low adherence to domiciliary NPPV caused CO2 narcosis; hence, we advised her to continue domiciliary NPPV and she complied. In May 2012, the now 79-year-old patient was admitted for acute exacerbation of chronic respiratory failure and CO2 narcosis. Chest imaging suggested that DH had caused a deterioration of her status. She underwent laparoscopic diaphragmatic hernia repair. Operative findings revealed a retrosternal hernia sac, and she was diagnosed as having a Morgagni hernia (MH). Her respiratory status subsequently improved. We hypothesize that NPPV increased intra-abdominal pressure, thereby worsening the MH and exacerbating respiratory failure. We believe that clinicians should be cautious when prescribing NPPV for MH patients.
