Prevalence of Diabetes Mellitus and Prediabetes in Dalseong-gun, Daegu City, Korea

BACKGROUND: The aim of the present study was to determine the population-based prevalence of diabetes mellitus (DM) and prediabetes in a rural district of Daegu City, Korea. METHODS: Between August and November 2003, a community-based health survey of adults aged 20 years and older was performed in the rural district of Dalseong-gun in Daegu City. A total of 1,806 of all eligible individuals agreed to participate. Fasting plasma glucose was measured in all participants. Two hour oral glucose tolerance was measured in the 1,773 participants for whom there was neither an established diagnosis of DM nor evidence of DM according to fasting glucose levels. The prevalence of DM and prediabetes was determined according to the 2003 criteria of the American Diabetes Association. Subjects with prediabetes were classified into one of three categories of glucose intolerance: isolated impaired fasting glucose (IFG); isolated impaired glucose tolerance (IGT); or combined IFG and IGT. RESULTS: The prevalence of DM was 12.2%. The highest prevalence rates were observed in subjects in their seventies. A total of 34.7% of all subjects who were assigned a diagnosis of DM in the present study had not been diagnosed previously. The prevalence of prediabetes was 22.7%. The highest prevalence rates were observed in subjects in their fifties. CONCLUSION: The present study identified prevalence rates of 12.2% for DM (age-standardized prevalence rate [ASR], 6.8%), and 22.7% for prediabetes (ASR 18.5%). These results emphasize the need for community health promotion strategies to prevent or delay the onset of DM in individuals with prediabetes.

Idiopathic hypereosinophilic syndrome associated with skin lesions and multiple brain infarctions / 대한내과학회지

Idiopathic hypereosinophilic syndrome (IHES) is a rare systemic disorder that's characterized by peripheral eosinophilia and eosinophilic infiltration of multiple organs, including the heart, lungs, skin, liver, gastrointestinal tract and nervous system. IHES is associated with a broad range of clinical findings, depending on the involved organ and the severity of the infiltration. The diverse modes of clinical presentation occasionally lead to a false clinical diagnosis. There are no specific tests for diagnosing IHES, and the therapies remain controversial. In this report, we describe a 34-year-old man with IHES that was associated with multiple brain infarctions in both cerebral and cerebellar hemispheres. Five months earlier, the patient presented with erythematous scaly hyperkeratotic skin lesions on both legs. He was treated with anticoagulation therapy, aspirin and topical corticosteroid for about 1 month. All his symptoms and signs dramatically improved, except for the persistent peripheral eosinophilia. On follow-up after 8 months, the patient remained well without relapse or new lesions.

A Case of Hyperthyroidism with Complete Atrioventricular Block and Cardiac Arrest / 대한내분비학회지

The cardiovascular manifestations of hyperthyroidism are sinus tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, atrioventricular block, bundle branch block, angina pectoris, heart failure, and cardiomyopathy. Though complete atrioventricular block is rare, it is important to recognize it in clinical practice because of the possibility of cardiac arrest. We experienced a 47-year-old female patient who had hyperthyroidism with complete atrioventricular block and developed cardiac arrest despite the initiation of an antithyroid drug. We could resuscitate successfully and inserted a temporary pacemaker, but eventually a permanent pacemaker was needed to prevent the recurrence of cardiac arrest. We report a rare case of complete atrioventricular block and cardiac arrest associated with hyperthyroidism with the review of references.

Spontaneous Aortic Dissection in a Patient with Neurofibromatosis

Neurofibromatosis type 1 (NF-1), or von Recklinhausen's disease, is an autosomal dominant disorder that primarily affects the skin, the central and peripheral nervous systems, and the skeleton. Vasculopathy, such as, aneurysm or stenosis of large vessels is a less common manifestation of NF-1, but spontaneous aortic dissection in NF-1 is very rare. We report a case of acute aortic dissection with incidental aneurysm of the right femoral artery in NF-1.

A Case of Pulmonary Alveolar Proteinosis Associated with Pulmonary Tuberculosis / 결핵

Pulmonary alveolar proteinosis(PAP) is a disorder in which an insoluble, proteinaceous material, rich in phospholipids, is deposited in the alveoli and bronchioles. The deficiency in the clearance and degradation of the i ntra-alveolar phospholipoproteinaceous material in PAP most likely represents a dysfunction of the type II pneumocytes. Although the pathogenesis and causative treatment of PAP is unclear a whole lung bronchopulmonary lavage is a relatively safe and effective treatment. Here we experienced a case of pulmonary alveolar proteinosis in a 62 year old female patient who had pulmonary tuberculosis approximately 20 years ago. She complained of aggravated dyspnea and chronic cough, and presented fine inspiratory crackles at both lung fields. diffuse ground glass opacity with some area of consolidation and smooth interlobular septal thickenings in both upper, right middle lobes, and a portion of right lower lobe. Optical microscopy of the lung tissue obtained by an open lung biopsy many granulomas containing acid-fast smear positive bacilli and diffuse homogeneous PAS-positive fluid in the alveolar space. Immunohistochemical stain showed surfactant A in the alveolar space. Antituberculosis drugs with bronchoalveolar lavage were used to treat the disease. There after she showed improvement in her symptoms and a partial improvement in the chest X-ray and HRCT findings. We present a case of PAT associated with pulmonary tuberculosis.
