Congenital dyserythropoietic anemia type II is the most frequent type. All types of congenital dyserythropoietic anemias distinctly share a high incidence of iron loading. Iron accumulation occurs even in untransfused patients and can result in heart failure and liver cirrhosis. We have reported about a patient who presented with liver cirrhosis and intractable ascites caused by congenital dyserythropoietic anemia type II. Her clinical course was further complicated by the development of autoimmune hemolytic anemia. Splenectomy was eventually performed which achieved complete resolution of ascites, increase of hemoglobin concentration and abrogation of transfusion requirements.展开更多

Methods: The study group comprised 72 patients with type-2 diabetes. Patients were divided into groups according to glycemic control, gender and age. Serum creatinine, hematocrit, hemoglobin concentration, blood glucose and glycated hemoglobin (HbA1c) of subjects were measured. The presence of anemia was defined by a he- moglobin level 7.5%) compared to those with controlled diabetes (≤7.5%) and in patients of age ≥ 60 yrs compared to those of age < 60 yrs (p < 0.05). The odds of anemia was similar in males and females (p = 0.26). Conclusion: This study indicated that poor glycemic control and old age are associated with the incidence of anemia in type-2 diabetics with normal renal function. Our findings suggest that treatment criteria for diabetes should include routine hematological tests and take into consideration the inevitable consequences of ageing, and poor glycemic control.展开更多

In addition, the incidence and risk of anemia in these patients were assessed according to gender and glycemic control status. Methods: The study group comprised 200 patients with type-2 diabetes. Patients were divided into groups according to glycemic control and gender. Glycated hemoglobin (HbA1c), blood glucose level, hemoglobin concentration, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) of subjects were evaluated. The presence of anemia was defined by a hemoglobin level 6.5%, fasting blood glucose >126 mg/dl and random blood glucose >200 mg/dl. Result: 63% of diabetic patients had anemia. There was higher incidence and risk of anemia in females (36%) as compared to males (27%) (p 7.5% (49.5%) compared to those with controlled diabetes HbA1C < 7.5% (13.5%) (p < 0.05). Conclusion: This study indicated that poor glycemic control and gender difference are associated with the incidence of anemia in type II diabetes. Our findings suggest the need of screening for anemia in diabetes out-patient clinics. Routine hematological tests along with blood glucose level should be mandatory in order to make therapeutic decisions for the treatment of anemia in type II diabetes mellitus.展开更多

This report describes the possibility of endoscopic treatment as an appropriate option for gastric carcinoid fulfilling certain conditions. A 46 year old woman underwent endoscopic mucosal resection for two 3 mm gastric carcinoids. The patient had hypergastrinemia with pernicious anemia and type A chronic atrophic gastritis, suggesting that the tumors were type Ⅰ in Rindi's classification. Both tumors were located in the mucosal layer with no cellular polymorphism and were chromogranin A positive. Neither tumor recurrence in the stomach nor distant metastases have been documented during the 5 years of follow-up. Although many type Ⅰ gastric carcinoids may be clinically indolent, reports on successful endoscopic treatment for this carcinoid have been scanty in the literature in Japan, presumably because of the hitherto surgical treatment stance for the disease. This report discusses how the size, number, depth and histological grading of the type Ⅰ gastric carcinoid could allow the correct identification of a benign or malignant propensity of anindividual tumor and how endoscopic resection could be a treatment of choice when these factors render it feasible. This stance could also obviate unnecessary surgical resection for more benign tumors.展开更多
