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.

Postpubertal mumps may result in ochitis and permanent testicular atrophy may develop following infection. This present study was initiated to evaluate the preventive effect of interferon-alpha2B on infertilty after mumps orchitis. There were 21 patients with mumps orchitis between May 1990 and June 1997. Patients were randomly distributed into 2 groups: group 1 patients (n=13) maintained therapy with interferon-alpha2B (3x10(6) IU per day) and group 2 were managed by conservatively. All of the patients were evaluated with testis size measurement, mumps virus titer, hormone level, and if possible semen analysis. For group 1 patients symptoms disappeared within 2 to 3 days and the volume of testis returned to normal within 11 days and testis atrophy was not observed in all patients in follow up. But asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). For group 2 patients symptoms disappeared within 5 to 6 days and the volume of testis returned to normal within 10 days and testis atrophy was observed in 3 patients (unilateral 2, bilateral 1) in floow up. Asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). Sperm count and morphology were recovered all the recover in group 1, 4 patients had persistent reduced sperm count and morphology in group 2, respectively. These observations suggest that systemic interferon-alpha2B treatment is highly effective in preventing infertility as well as testicular atrophy after mumps orchitis.

Nasopharyngeal teratomas are rare congenital tumors which mainly cause neonatal respiratory difficulty or feeding problems. We report an extremely rare case of nasopharyngeal teratoma in which a 34-year-old woman experienced a foreign body sensation. Simple radiographs and CT scans revealed the presence of an exophytically growing mass with a region of fatty attenuation and a well-formed tooth in the nasopharyngeal wall. The mass was surgically removed, and found at histopathology to be a mature teratoma.

Pericardial effusions can be developed by any form of pericarditis; infective pericarditis such as viral or bacterial infection and non-infective, inflammatory pericarditis related with generalized disease such as end-stage renal disease or connective tissue disease and irradiation, postpericardiectomy syndrome, drugs and non-inflammatory pericarditis by malignancy, hypothyroidism, trauma on chest. In children, pericardial effusions are usually related with viral infection, generalized disease or cardiac surgery. We experienced three unusual cases of pericadial effusion by Mycoplasma pneumonia infection, Rickettsia tsutsugamushi infection and post-thoracotomy effusive constrictive pericarditis.

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.

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.

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.
