A 56-year-old female initially visited an otorhinolaryngologist because of an impaired sense of taste in September, 2010 and was referred to our facility in October, 2010. She was diagnosed with Basedow's disease for which she underwent subtotal thyroidectomy in 1984 and arthritis involving multiple joints, primarily affecting her hands. In addition, the anticentromere antibody (ACA) level was markedly high. On physical examination, alopecia as well as hyperpigmentation of the dorsum of the hands and back was observed. Dystrophic changes of the fingernails and a bilateral thumb abduction deformity were observed. Antinuclear antibodies were elevated. Gastrointestinal endoscopy and colonoscopy revealed the mucosa carpeted with strawberry-like polypoid lesions. Histopathological examination of the biopsied specimen of the stomach revealed a corkscrew-like appearance. Thus, the patient was diagnosed with Cronkhite-Canada syndrome (CCS). She admitted to our hospital in November, 2010. Oral prednisolone was administered with success. In July, 2012, her antimitochondrial M2 antibody level was elevated. To the best of our knowledge, the present case is the first patient with CCS, a history of Basedow's disease, and elevated levels of ACA and antimitochondrial M2 antibody. We consider the present case suggests CCS could be caused by immunological abnormality.
Case 1. The laboratory findings of a hematological analysis of a 53-year-old woman with palpitations and dyspnea revealed the following: red blood cell (RBC) count: 9.4×10 5 /μL with 60.0‰ reticulocytes; Hb: 3.7 g/ dL; mean corpuscular volume (MCV): 124.5 fL; white blood cell (WBC) count: 2,800/μL with 10.0% myeloblasts. Case 2. Similarly, a 42-year-old man with dizziness had a RBC count of 1.63×10 6 /μL with 24.0% reticulocytes, an Hb level of 6.0 g/dL, an MCV of 120.2 fL and a WBC count of 3,100/μL with 4.0% myeloblasts. Bone marrow aspirates in both patients confirmed a diagnosis of acute erythroid leukemia (AEL), which can present as marked macrocytic anemia with an MCV in excess of 120 fL and hemolysis.
A 78-year old woman with complicating solitary kidney had nephrotic syndrome. Renal biopsy specimens showed focal segmental glomerulosclerosis (FSGS). First, the patient was treated with angiotensin receptor blocker (ARB) and angiotensin converting enzyme inhibitor (ACEI). Proteinuria decreased from 10 to 6 g/day, but overall the nephrotic syndrome did not improve. Additional treatment with prednisolone and cyclosporine reduced proteinuria to less than 1.0 g/day. We report that combination therapy with ARB, ACEI, prednisolone, and cyclosporine was successful for FSGS complicating solitary kidney.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
