1.Echocardiographic Diastolic Left Atrial Emptying Index in Hypertensive Patients.
Korean Circulation Journal 1984;14(1):95-102
M-mode echocardiography has been demonstrated to be a sensitive indicator of the sequential changes occurring in the heart in systemic arterial hypertension. The changes in function as well as anatomic features have been recorded. Previous analysis has focused on the anatomy and systolic function of the left ventricle, analysed in hypertensive heart disease. 13 normal subjects(Group I), 14 hypertensive patients without evidence of cardiac involvement(Group II) and 13 hypertensive patients with echocardiographic evidence of left ventricular hypertrophy(Group III) were compared using M-mode echocardiographic data and clinical. findings. The results are as follows : 1) Mean age are; Group I : 41 years(19-62), Group II : 49 years(25-67) and Group III : 53 years(30-83). There are no significant age difference between Group I and II. Sex ratio are 4:9, 8:6 and 7:6 respectively. 2) Mean arterial pressure are; Group I : 98+/-5mmHg, Group II : 126+/-7 mmHg and Group III : 131+/-101mmHg. 3) Left ventricular posterior wall thickness are; Group I : 0.87+/-0.12cm, Group II : 0.89+/-0.12cm and Group III : 1.32+/-0.18cm(p>0.05 in I vs II). 4) Left atrial dimension are; Group I : 2.77+/-0.68cm, Group II : 2.96+/-0.44cm and Group III: 3.12+/-0.60cm. 5) Left ventricular mass arel Group I : 194+/-51gm, Group II : 192+/-51gm and Group III : 318+/-77gm(p>0.05 in I vs II, p<0.001 in I vs II and II vs III). 6) Ejection fraction are; Group I : 0.57+/-0.09, Group II : 0.60+/-0.01 and Group III : 0.52+/-0.01)p>0.05). 7) Mitral valve EF solpe are; Group I : 113.70+/-23.26mm/sec, Group II : 81.14+/-17.22mm/sec and Group III : 69.92+/-22.70mm/sec(p<0.05 in I vs II, p<0.001 in I vs III and II vs III). 8) AEI are; Group I : 0.70+/-0.04, Group II : 0.56+/-0.07 and Group III: 0.48+/-0.07)p<0.001 in I vs II, I vs III and II vs III). From the above results, the atrial emptying index seems to be an early indicator of abnormalities of left ventricular diastolic compliance in hypertensive patients.

Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

When a soft tissue mass in the bony wall of the paranasal sinus is present, it is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific area on CT. This is a report of four proven cases of fungal sinusitis, asperogillosis in 3 cases and mucormycosis in 1 case, All 4 patients had CT and one patient had MRI, On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.

Remnant thyroglossal ducts are common developmental abnormalities of the thyroid gland. The malignant transformation of these structures is extremely rare. Even though a malignancy it is highly suspected in elderly patients with midline neck swelling, the diagnosis is seldom made preoperatively. In thyroglossal duct carcinomas, a papillary carcinoma is the most common pathologic finding. The etiology of such tumors is unclear, but a de novo origin and spread from primary thyroid-gland tumors has been suggested. There are different theories regarding the origin of and the therapy for these malignancies. This has important significance for therapeutic approaches. We report a case of a papillary cancer arising in a remnant thyroglossal duct which was managed by Sistrunk's operation and right thyroid lobectomy.

Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.
