The sensitivity and specificity of ST segment change on ECG for detection of coronary artery disease(CAD) by pacing stress test were assessed. Among 28 cases with chest pain(mean age 52, M/F : 21/7), 10 patients had normal coronary angiographic finding(Group I), and 18 had coronary artery disease(Group II). Pacing stress test showed high specificity(100%), but low sensitivity(61%) for the diagnosis of CAD. Especially in patients with 1 vessel disease, the sensitivity was only 50%, and positive results were not attained unless there was at least 90% or more stenosis in any of the major branches(LAD, RCA or LCX). But in patients with multivessel disease, the sensitivity was much higher(83%). Lateral(V4-6) or inferior leads(2, 3, aVF) showed ischemic ST segment depression most commonly. Therefore one of the inferior lead and V5 may be a minimum requirement for monitoring pacing-induced ST segment changes. Time constant during isovolumic relaxation showed statistically significant prolongation after pacing only in CAD patient group, suggesting pacing-induced impairment of early left ventricular relaxation.

Sinonasal lymphomas are relatively uncommon and represent less than 1% of all head and neck malignancies. It is absolutely rare in the United States but its incidence has been reported to be higher in Asian and South American. A primary malignant lymphoma in the paranasal sinuses usually occurs in the maxillary or ethmoid sinus, and it is very rare in the sphenoid sinus. We present a case of a 48-year-old male patient, who complained both of reduced visual acuity and diplopia for a week. An opthalmologic examination revealed no light perception of the right eye. A nasal endoscopy revealed yellowish crusts and a mucosal swelling in both nasal cavity, but no definite mass like lesion was found in the nasal cavity. CT scans of sinuses demonstrated mass lesions in the posterior ethmoid and sphenoid sinus and on the suprasellar area. A mass showed up in the T1 and T2 intensified MR image. He was required to get biopsy for definite diagnosis at the operating room by endoscopic technique, which then allowed it to be pathogenically characterized as angiocentric immunoproliferative lesion (AIL). The lesion was finally defined as T-cell lymphoma by immunochemical study, which showed it to be positive to CD45Ro. After the patient underwent mass biopsy, he received steroid therapy for 5 days. And then both visual acuity was improved abruptly. The patient was treated with both chemotherapy (CHOP) and radiation therapy (4400 cGy). He has been in complete remission state for 1 year after a combination therapy.

BACKGROUND: Acute interstitial pneumonia is a relatively rare form of interstitial pneumonia, since the vast majority of interstitial pneumonia have a more chronic course. It corresponds to the lesion described by Hamman and Rich, as Hamman-Rich disease in 1944. Another name in the clinical literature is accelerated interstitial pneumonia, idiopathic acute respiratory distress syndrome (idiopathic ARDS), and the organizing stage of diffuse alveolar damage. Acute interstitial pneumonia differs from chronic interstitial pneumonia by clinical and pathologic features. Clinically, this disease is characterized by a sudden onset and a rapid course, and reversible disease. METHOD AND PURPOSE: Five cases of pathologically proven acute interstitial pneumonia were retrospectively studied to define the clinical, radiologic, and pathologic features. RESULTS: 1) The five cases ranged in age from 31 to 77 years old. The onset of illness was acute in all patients, it began with viral-like prodrome 6~40 days prior to shortness of breath, and respiratory failure eventually developed in all patients. In 2 cases, generalized skin rash was accompanied with flu-like symptoms. Etiologic agent could not be identified in any case. 2) All patients had leukocytosis and severe hypoxemia. Pulmonary function test of 3 available cases shows restrictive ventilatory defect, and one survived patient(case 5) has a complete improvement of pulmonary function after dismissal. 3) Diffuse bilateral chest infiltrates were present radiologically. Theses were the ground-glass, consolidation, and reticular densities without honeycomb fibrosis in all patients. The pathologic abnormalities were the presence of increased numbers of macrophages and the formation of hyaline membranes within alveolar spaces. There was also interstitial thickening with edema, proliferation of immature fibroblast, and hyperplasia of type II pneumocyte. In the survived patient(case5), pathologic findings were relatively early stage of acute interstitial pneumonia, such as hyaline membrane with mild interstitial fibrosis. 4) Of the 5 patients, four patients died of respiratory failure 14~90 days after onset of first symptom, and one survived and recovered in symptoms, chest X ray, and pulmonary function test CONCLUSION: These results emphasize that acute interstitial pneumonia is clinically, radiologically, and pathologically distinct form of interstitial pneumonia and should be separated from the group of chronic interstitial pneumonia. Further studies will be needed to evaluate the pathogenesis and the treatment of acute interstitial pneumonia.

BACKGROUND: Dipeptidyl peptidase 4 (DPP-4, also known as CD26) binds with adenosine deaminase (ADA) to activate T lymphocytes. Here, we investigated whether ADA activity is specifically affected by treatment with DPP-4 inhibitor (DPP4I) compared with other anti-diabetic agents. METHODS: Fasting ADA activity, in addition to various metabolic and biochemical parameters, were measured in 262 type 2 diabetes mellitus (T2DM) patients taking various anti-diabetic agents and in 46 non-diabetic control subjects. RESULTS: ADA activity was increased in T2DM patients compared with that in non-diabetic control subjects (mean+/-standard error, 23.1+/-0.6 U/L vs. 18.6+/-0.8 U/L; P<0.05). ADA activity was correlated with fasting plasma glucose (r=0.258, P<0.05), HbA1c (r=0.208, P<0.05), aspartate aminotransferase (r=0.325, P<0.05), and alanine aminotransferase (r=0.248, P<0.05). Compared with the well-controlled T2DM patients (HbA1c<7%), the poorly controlled group (HbA1c>9%) showed significantly increased ADA activity (21.1+/-0.8 U/L vs. 25.4+/-1.6 U/L; P<0.05). The effect of DPP4I on ADA activity in T2DM patients did not differ from those of other oral anti-diabetic agents or insulin. T2DM patients on metformin monotherapy showed a lower ADA activity (20.9+/-1.0 U/L vs. 28.1+/-2.8 U/L; P<0.05) compared with that of those on sulfonylurea monotherapy. CONCLUSION: Our results show that ADA activity is increased in T2DM patients compared to that in non-diabetic patients, is positively correlated with blood glucose level, and that DPP4I has no additional specific effect on ADA activity, except for a glycemic control- or HbA1c-dependent effect.

Lesch-Nyhan syndrome is an X-linked recessive disorder characterized by hyperuricemia, choreoathetosis, spasticity, mental retardation, and compulsive, self-injurious behavior. This disorder results from a complete deficiency of the purine salvage enzyme, hypoxanthine-guanine phosphoribosyl transferase(HPRT). We report here on a case of Lesch-Nyhan syndrome in a 1-year, 7-month-old male who presented with frequent vomiting, failure to thrive, and developmental delay. The diagnostic work-up revealed hyperuricemia, hyperuricosuria, and medullary nephrolithiasis. The HPRT activity in the erythrocytes was undetectable with a biochemical assay. We also identified de novo mutation which was a deletion of the 649th base, adenosine, in HPRT gene(649delA) by analysis of cDNA using RT-PCR technique coupled with direct sequencing.

A 47-year-old patient with diabetes mellitus was admitted with the complaints of sore throat and dysphagia. We performed an esophagogastroduodenoscopy and found esophageal ulcers. Histological examination of the esophageal biopsy revealed sulphur granules, and immunological findings ruled out viral infection. Thus, we diagnosed an isolated actinomycotic infection of the esophagus and treated the infection with oral amoxicillin. This case illustrates that actinomycotic infection of the esophagus can occur in immunocompetent patients. Therefore, when evaluating dysphagia, the probability of actinomycotic infection must be considered not only in immunocompromised patients, but in immunocompetent individualswith diabetes mellitus.

Cardiac calcification usually occurs in patients with end-stage renal disease. However, rapid progression of cardiac calcification is rarely associated with secondary hyperparathyroidism of end-stage renal disease. We report a patient with end-stage renal disease who showed moderate left ventricular hypertrophy at the first echocardiography, and showed severe myocardial calcification and severe mitral valve stenosis 4 years later. We suspected a rapid progression 'porcelain heart' cardiomyopathy secondary to hyperparathyroidism of end-stage renal disease. The patient underwent parathyroidectomy, and considered mitral valve replacement.
