Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

Intraaortic balloon counterpulsation (IAB) has been shown to prolong survival in the critically ill cardiac patients. Originally developed for use in the patients with cardiogenic shock, the indications have been expanded. But despite technical advances, the complication rate associated with IAB remains high. The most commonly reported complications include damage to the femoral artery and distal embolization. Other reported major complications are balloon rupture, limb loss, bleeding, systemic infection and bowel infarction. We report a patient complicated by ischemic colitis causing stenosis and intestinal obstruction after IAB insertion.

PURPOSE: To describe the imaging findings of traumatic intracranial aneurysms (TICA) in children. MATERIALS AND METHODS: Five boys aged 3-15 (mean, 7) years with surgically confirmed TICA were included in this study. All had a history of nonpenetrating head trauma, and they underwent precontrast CT imaging immediately after the injury and follow-up CT or MRI. In all cases, angiography revealed the presence of aneurysms, which at surgery were shown to be pseudoaneurysms with severe adhesions. RESULTS: Angiography demonstrated that all aneurysms were located in the anterior cerebral artery (ACA) or its branches. The precise locations were the A2 segment of the ACA, the site of origin of the callosomarginal artery or its first branch, or of the anterior internal frontal artery, or between the first and second branch of the pericallosal artery. In all patients, precontrast CT performed immediately after trauma depicted subarachnoid hemorrhage (SAH) in the anterior interhemispheric fissure (AIHF). Follow-up precontrast CT showed nodular high density around the anterior falx in three, recurrent SAH in the AIHF in two, and intracerebral hemorrhage (ICH) with intraventricular hemorrhage in two. In two patients with a nodular high-density lesion, nodular enhancement was demonstrated at postcontrast CT, and in one, follow-up MRI revealed a nodular signal void around the anterior falx; nodular enhancement was seen at postcontrast imaging, and MR angiogram depicted a saccular aneurysm. In one patient, MRI demonstrated infarction in the caudate nucleus and ACA territory. CONCLUSION: If, after head injury, an area of nodular high density is revealed by CT, or a signal void by MRI, or if SAH or ICH is present around the anterior falx, the possibility of TICA should be considered.

PURPOSE: The separation of prescription and dispensation of drugs starting from July 2000 has led to a reduced exposure to drugs for the general population. Therefore, we hypothesize that the policy of separation the prescribing and the dispensing of drugs has decreased the actual incidence of drug intoxication from drug abuse. METHODS: Patients with acute intentional drug intoxication who were admitted to emergency centers in Seoul were retrospectively studied. The study period was subdivided into three: before, during, and after the launch of the policy of separation of prescription and dispensation, corresponding to the periods January to June, 2000; January to June 2001; and January to June 2002, respectively. RESULTS: Acute drug intoxication was associated with 0.2% of all prescriptions during the studied period. There was no significant difference in the types of intoxicating drugs whereas the most commonly abused drug was Doxylamine succinate. Prescribed medications accounted for 37.0%, 29.2%, and 32.3% of the acute drug intoxication cases in 2000, 2001, and 2002, respectively. There was no significant difference in the treatment outcomes between the three study groups although three patients died of paraquat intoxications in 2001. CONCLUSION: The launch of the policy of separation of prescription and dispension of drugs did not significantly reduce the rate of acute drug intoxication from drug abuse which questions the effectiveness of the policy in decreasing drug abuse. We suggest reassessment of sedatives, in particular, those prescribed medications, in order to decrease the incidence of acute intoxications.

Perinatal atrial flutter is a potentially lethal arrhythmia. Management of this disorder is difficult and controversial. Fetal atrial flutter is a serious and life threatening rhythm disorder particulary when it causes hydrops; it may be associated with fetal death or neurological damage. Although the initial episode of flutter may be difficult to control, recurrence of atrial flutter after successful resolution of the arrhythmia seems highly unlikely and long-term prognosis is excellent. We experienced a case of a atrial flutter diagnosed in utero at 38+6 weeks' gestation by fetal cardiac echocardiography. He was treated with maternal digoxin, but he continued to have atrial flutter until delivery. Restoration of sinus rhythm occured with propafenone therapy in this patient after failure of initial digoxin therapy and direct current cardioversion.

BACKGROUND AND OBJECT: We want to know reference values of mitral annulus velocity by Doppler tissue imaging which has been thought as a new parameter of left ventricular diastolic function. Including mitral inflow parameters, many parameters which have been used in the evaluation of left ventricular diastolic function are affected by several conditions, so sometimes they can not provide information about left ventricular diastolic function. The knowledge of mitral annulus velocity by Doppler tissue imaging will provide new guidelines for evaluation of diastolic function. However, reference values in normal and changes according to an age have not been fully evaluated. METHODS: We examined 246 patients with no symptoms related to the cardiac systolic and diastolic dysfunction and 80 healthy volunteers according to an age. Early ( E ) and late ( A ) transmitral flow velocity and the ratio of early to late peak velocity ( E/A ) were obtained by pulsed Doppler echocardiography. Early diastolic velocity of mitral annulus ( E' ) and peak atrial systolic velocity of mitral annulus ( A' ) were obtained from the medial ( or septal ) corner of the mitral annulus and subsequently from lateral corner by Doppler tissue imaging. We obtained E', A' and the ratio of E' to A' ( E'/A' ) and E/ E' according to an age. RESULTS: E' from medial corner was the highest in subjects in their twenties and declined gradually and A' from medial corner was the lowest in a same age group and increased gradually. E'/A' ratio from medial corner was the highest in subjects in their twenties and declined gradually and reversed in subjects in their forties. E', A' and E'/A' from lateral corner were showed like as medial corner similarly but E'/A' was reversed in the subjects in their fifties. E/ E' from medial and lateral corner was the lowest in subjects in their twenties and increased gradually with age. In comparison between transmitral flow velocity and mitral annulus velocity, there are good relationship in E/A and E'/A' ( p=0.01 ). CONCLUSION: We measured reference values of mitral annulus velocity by Doppler tissue imaging and E/ E' according to an age.

Injury to a peripheral nerve due to a drug injection is of particular concern, because of both its clinical and medicolegal implications. Among numerous agents, local anesthetic solutions are most frequently injected near the main nerve trunks. In spite of the low incidence of nerve fiber injury associated with these local anesthetic agents, there are several clinical reports of injury. The author experimentally induced injection injury into the rat sciatic nerve with 2% lidocaine HCL and 0.5% bupivacaine. The neurotoxicity of these agents to the peripheral nerve was observed by light and electron microscope. The results are as follows: 1) Some inflammatory round cells and vasodilation were observed in the surrounding loose areolar tissues immediately after injection. No fibroblast or fibrosis was observed on light and electron microscopic examinations. 2) Immediately after injection, the axons were seperated by the splitting of the collagen fibers between the axons. But within one week, the collagen fibers were reunited and compacted. 3) Most cytoplasmic organelles of the axon, including the microtubules and micro filaments, were quite normal and were not altered by injection injury. But the shape of the axon was changed and shrinked to create a large space from the myelin sheath. The above change returned to normal within one week. 4) The Schwann cells, maintained the normal structure of their cytoplasm and nucleus, but some Schwann cells were seperated from the axons, and floated in the collagen tissue. They were reunited with the axons within one week. 5) There were no significant histologic differences between lidocaine and bupivacaine. 6) The above changes were easily reversible and not severe enough to interfere with nerve function permanently. In conclusion, local injection of these agents is very safe to the peripheral nerve.

PURPOSE: The osmolar gap increases in proportion to the ethanol level. Some previous studies have shown that the correlation between the osmolar gap and the ethanol level is weak in trauma patient by using an indirect comparison with other patients. We conducted a direct comparison of the correlation of the osmolar gap to the ethanol level between trauma patients and non-trauma patients. We also analyzed the accuracy of the estimated ethanol level between the two groups. METHODS: The research candidates were adult patients who had visited the emergency department of our hospital from December 2003 to November 2008. By using a retrospective chart review, we classified them into three subgroups: non-trauma without shock, trauma without shock, and trauma with shock. In each group, we compared the correlation between the osmolar gap and the measured ethanol level, and we analyzed the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient. RESULTS: Four hundred forty-seven patients were enrolled in this study. For correlation of the osmolar gap and the measured ethanol level, Pearson's correlation coefficient was 0.916 in all patients, 0.939 in non-trauma without shock patients, 0.917 in trauma without shock patients, and 0.844 in trauma with shock patients. In the analysis of the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient, the accuracy in trauma with shock patients was lower than that in non-trauma without shock patients. CONCLUSION: We found that the correlation between the osmolar gap and the measured ethanol level in the patient group with trauma was lower than it was in the patient group without trauma. Moreover trauma patients with shock had a lower accuracy of the estimated ethanol level than non-trauma patients.

PURPOSE: Whereas sexual function has long been assumed to be an important component of adult men's lives, the impact of sexual dysfunction has not been estimated in parallel to other modern disease entities. We compared the seriousness of erectile dysfunction (ED) with that of other diseases by use of self-administered questionnaires. MATERIALS AND METHODS: Between January 2012 and July 2012, 434 healthy male volunteers (group 1) and 263 ED patients (group 2) were enrolled. The questionnaire consisted of the following: "If you must undergo only one disease in all your life, which disease could you select among these items or ED?" The comparative disease entities included hypertension, diabetes mellitus (oral hypoglycemic agent/insulin injection), hemodialysis, myocardial infarction, herpes zoster, chronic sinusitis, chronic otitis media, gastric cancer (early/late), lung cancer (early/late), liver cancer (early/late), and dementia. RESULTS: Group 1 recognized ED as being a more serious disease than hypertension, diabetes mellitus (oral hypoglycemic agent), herpes zoster, chronic sinusitis, and chronic otitis media. In comparison, group 2 recognized ED as being a more serious condition than diabetes mellitus (insulin injection) and dementia (p<0.001 and p<0.001, respectively). In particular, ED was deemed to be more serious than hemodialysis, gastric cancer (early), lung cancer (early), and liver cancer (early) by men in group 2 in their 30s to 40s, and these results were statistically significant compared with the same age subgroups in group 1 (p<0.001, p<0.007, p<0.02, and p<0.007, respectively). CONCLUSIONS: In contrast with their healthy counterparts, Korean men with ED recognized ED as being as serious as hemodialysis, dementia, and early stage cancer, which reflects the severe bother of ED in Korean patients.
