1.A Case of Intrapericardial Cystic Teratoma.
Korean Circulation Journal 2000;30(9):1175-1178
Teratoma of the heart is very rare and occurs mainly in children. A 44-year-old male patient was admitted due to foreign body sensation on throat and chest discomfort for a month. Chest CT, MRI and trans- thoracic and transesophageal echocardiographies showed 12x10 cm sized cystic mass with septataion and solid nodules, combined with pericardial and pleural effusion. Excision of the tumor was done and the pathologic diagnosis was mature cystic teratoma arising from pericardium.

Succinylcholine (Sch) has long been used to facilitate laryngoscopy and endotracheal intubation for general anesthesia, because of a rapid onset of intense but brief paralysis. However, exaggerated potassium (K+) release following Sch, sufficient to cause ventricular dysrhythmias and cardiac arrest, has sporadically been reported in susceptible conditions, including spinal cord injury, severe burn, massive trauma and neuromuscular disorder. And diazepam has been shown to attenuate the increase in serum K+ following Sch administration. The purpose of this study was to assess the effect of Sch on serum K+ in patients with spinal cord lesions, and to assess the effect of pretreatment with diazepam (0.05 mg/kg IV) on potassium flux. The results were as follows: 1) Baseline K+ values were not significantly different among the groups. 2) The time to peak increases in K+ was 3 minutes following Sch in all groups. 3) The magnitude of maximum increases in K' following Sch were 0.32 Eq/l, 0.63 mEq/l, 0.06 mEq/I and 1,10 mEq/I in group 1, group 2A, group 2B, and group 3, respectively. 4) Diazepam pretreatment attenuated the increases in K+ following Sch. From the above results, it can be concluded that Sch may safely be used to facilitate intubation in paraplegic patients, provided that they are normokalemic and pretreated with diazepam.

Making impression is the first step of making hearing aid. Because it needs silicon injection on external auditory canal and lateral side of tympanic membrane, careful evaluation is required regarding the presence of any tympanic perforation or problems of external auditory canal prior to making ear impression. Recently, we experienced encountering one case of foreign body in ear while making impression of hearing aid by a local hearing aid seller. Silicone mold material, impacted into the middle ear, had perforated the tympanic membrane; a metallic foreign body was also found in the eustachian tube. Reporting this case, we suggest that special attention be paid to tympanic membrane and external auditory canal conditions when making an ear impression for hearing aids. Therefore, physical examination by otolaryngologist should precede any application of hearing aid.

Multiple sclerosis (MS) is a chronic disease characterized by multiple areas of demyelination, inflammation, and glial scarring in the central nervous system. MS is the most common chronic and usually progressive neurologic disease whose clinical course varies from a benign and symptom-free disease to a rapidly progressive and disabling disorder. MS can be presented with various symptoms, but isolated vertigo, represented in only 5%, is very rare. Nevertheless, in such a case, differential diagnosis of peripheral vestibular disease is very important for neuro-otologist. We recently experienced a 39 year-old female patient of multiple sclerosis with isolated vertigo mimicking vestibular neuritis. We report our case with a review of literature.

Non-Hodgkin's lymphoma (NHL) is a group of neoplasm affecting the lymphoid system. Follicular lymphoma is typically a slow-growing, indolent form of NHL that accounts for 1/3 of all NHL. It is one of the B-cell lymphomas, generally characterized by multiple relapses after responses to a variety of therapies. When lymphoma relapses, it may occur in the same or a different part of the body from where it occurred originally. Recurrence in the primary site is most common but recurrence in other parts is rarely observed. We experienced a rare case of 70-year-old woman who complained of swelling in the left mouth floor and was diagonosed with a recurrent NHL. It recurred in the sublingual gland after a complete remission of the follicular lymphoma.

BACKGROUND AND OBJECTIVES: An anatomic variant of left anterior descending coronary artery (LAD), termed "dual LAD", consists of early bifurcation of the proximal LAD into one early terminating branch (short LAD) which remains in the anterior interventricular sulcus (AIVS) and doesn't reach the apex, and the second (long LAD), which has a variable course outside the AIVS but returns to the distal sulcus and continues to the apex. Its incidence, angiographic features and clinical significance are investigated. MATERIALS AND METHOD: Consecutive 696 coronary angiograms during October 1997 through August 1998 were analyzed. RESULTS: A dual LAD variant was noted in 45 patients (6%) of the 696 patients. Type I, in which the long LAD descends on the left ventricular side of the AIVS before reentering the AIVS, was noted in 24 patients (53%) and type II, in which the long LAD descends on the right ventricular side of the AIVS before reentering the AIVS, in 21(47%). First septal branch was commonly originated from LAD proper in both type (54% vs 52%), but first diagonal branch from LAD proper (63%) in type I, from short LAD (71%) in type II. Presence of dual LAD was recognized before percutaneous coronary intervention (10) or bypass surgery (2) in 12 (63%) of 19 patients. Regional wall motion abnormalities (RWMA) were localized in distal septum or anterolateral wall in 2 patients with short or long LAD obstruction, respectively. CONCLUSION: Recognition of dual LAD is essential to prevent errors of interpretation of the coronary angiogram, to plan optimal strategy for percutaneous coronary intervention or bypass surgery, especially in case of total occlusion, and to understand localized septal or anterolateral RWMA.

Although central catheter-related complications are frequently reported and are inevitable in the neonatal care unit, the incidence of pericardiac tamponade is low but may be fatal. Index of suspicion, prompt diagnosis, and urgent pericardiocentesis are crucial for lifesaving. We encountered two premature cases of central venous catheter-related pericardial tamponade. The first case was a 4-day-old male premature infant (gestational age [GA], 33(+5) weeks; birth weight [BW], 1,864 g), and the second case was a 4-day-old female premature infant (GA, 28(+6) week; BW, 1,050 g). Each infant had an indwelling central venous catheter since birth and at the third day of hospitalization. The conditions of the babies suddenly deteriorated, but both babies were successfully resuscitated with urgent echocardiography and prompt pericardiocentesis.

BACKGROUND: The cis-AB is a very rare phenotype in the ABO blood group system. It corresponds to a special ABO allele that encodes glycosyltransferase that is capable of synthesizing both A and B antigens. Until now, the exon 6 and 7 gene sequences of cis-AB alleles are well known. In this study, we report on the intron 6 sequence structure of the cis-AB allele. METHODS: Standard serologic tests for the ABO blood group phenotypes were performed in four cis-AB samples. Allele-separation by cloning and subsequent sequencing was carried out. RESULTS: The results showed that intron 6 of cis-AB is almost identical to the A101 allele except for three single nucleotide polymorphisms at nucleotide positions 163, 179 and 662, where the nucleotides of the A101 replace those of B101. CONCLUSION: The intron 6 sequences of cis-AB in Koreans have both A101 and B101 blood group sequences.

The prevalence of group B streptococcus (GBS) among pregnant women and disease burdens in neonates and adults are increasing in Korea. Colonizing isolates, collected by screening pregnant women (n=196), and clinical isolates collected from clinical patients throughout Korea (n=234), were serotyped and screened for antibiotic resistance. Serotype III (29.8%) and V (27.7%) predominated, followed by Ia (17.0%). Antibiotic resistance was higher among clinical than colonizing isolates for erythromycin (35.1% and 26.9%; P=0.10) and for clindamycin (49.4% and 42.1%; P=0.17). erm(B) occurred in 91.9% of erythromycin resistant isolates, and 84.0% of isolates resistant to clindamycin. Only five isolates (4.2%) resistant to erythromycin were susceptible to clindamycin; by contrast, and unique to Korea, 34% of isolates resistant to clindamycin were erythromycin susceptible. Among these 60 erythromycin-susceptible & clindamycin-resistant isolates, 88% was serotype III, and lnu(B) was found in 89% of strains. Four fifths of the serotype V isolates were resistant to both erythromycin and clindamycin. Further characterization of the genetic assembly of these resistance conferring genes, erm(B) and lnu(B), will be useful to establish the clonal lineages of multiple resistance genes carrying strains.
