Doppler Tissue Image for Diagnosis of Myocardial Dyssynchronicity in Congestive Heart Failure: Comparison with EKG

BACKGROUND AND OBJECTIVES: Electrical dyssynchronicity (Dsyn) appears to be prognostic of survival in congestive heart failure (CHF). Recent study has shown some discrepancy between the electrical Dsyn and the Doppler tissue image (DTI) assessed mechanical Dsyn. The aim of our study was to evaluate the relationship between the QRS duration and DTI assessed Dsyn. SUBJCETS AND METHODS: One hundred and forty patients, with CHF and left ventricular ejection fractions 130 msec, standard deviation (SD) of the RS time >40 msec, or a difference in the maximal and minimal RS times (RS time-diff) >100 msec were indicators of'Dsyn'. RESULTS: The prevalence of myocardial Dsyn, by QRS duration, SD of the RS time and the RS time-diff were 19, 43 and 47%, respectively. The SD of the RS time (49.8+/-23.6 vs. 36.6+/-20.7, p130 msec) compared with the narrow QRS group. There was also a weak positive correlation between the QRS duration and the SD of the RS time (R=0.34, p<0.001) and the RS time-diff (R=0.38, p<0.001). However, from a cross-tabulation analysis, more than one third of patients had a discrepancy between QRS duration and DTI assessed mechanical Dsyn. From a multivariate analysis, a major determinant of the SD of the RS time was the QRS duration. CONCLUSION: Although a major determinant of the DTI assessed Dsyn was the QRS duration, more than one-third of patients had a discrepancy between electrical and mechanical Dsyn. Therefore, not only the QRS duration, but the DTI assessed Dsyn, should be measured when considering cardiac resynchronization therapy.

A Case of Spindle Cell Carcinoma of the Esophagus / 대한소화기내시경학회지

Spindle cell carcinoma of the esophagus containing both carcinomatous and sarcomatous elements is rare, accounting for approximately 1- 2% of all esophageal neoplasms. Terms used to describe this lesion include carcinosarcoma, pseudosarcoma, polypoid carcinoma, pseudosarcomatous squamous cell carcinoma and spindle cell variant of squamous cell carcinoma. Spindle cell carcinomas were originally classified as carcinosarcomas or pseu- dosarcomas, depending on the morphology and bilologic behavior of the particular lesian. However, pseudosarcoma and carcinosarcoma appear to be the same pathologic entity with varying degrees of anaplastic spindle cell metaplasia of the carcinomatous portion of the tumor. Thus, these lesions have been clsssified together as spindle cell carcinomas. A 59 year-old man who experienced weight loss for 4 months was hospitalized as a result of suffering from dysphagia for 2 months. A diffuse bulky protruding mass with superficial ulceration and easy friability on 25 to 35 cm from the incisors, which invaded the right intermediate bronchus and involved the right paratracheal and subcarnial lymph nodes, were obsetved in esophagogram, endoscopy and chest CT. Pathologic finding, including immunoreactivity to cytokeratin and vimentin, was consistent with spindle cell carcinoma. We report a case of spindle cell carcinoma of the esophagus.

A Case of Gastric Anisakiasis Causing Mallory - Weiss Syndrome / 대한소화기내시경학회지

Anisakiasis is an infection in humans caused by larval nematodes of the family Anisakidae and is encountered in people who eat inadequately prepared raw, salt-water fish or "sashimi". This clinical syndrome is characterized by severe cramping abdominal pain, nausea, and vomiting. Because Koreans like to eat raw fish, anisakiasis of the stomach has been reported occasionally, but the incidences of upper gastrointestinal bleeding caused by anisakiasis has been very rare. The present case is a 30 year-old male Admitted with an episode of hematemesis. A gastrofibroscopy revealed a mucosal laceration and the larva of Anisakis on the esophagogastric junction. We report one case of Mallory-Weiss Syndrome due to gastric Anisakis larva, confirmed by an endoscopy.
