OBJECTIVES: The objectives of this study is to compare the differences of fetal heart rate (FHR) variables between preterm and term pregnancies after acoustic stimulation using computerized analysis of fetal heart rate. METHODS: Eighty-two normal pre-term and term pregnancies entered to this study after conventional 20-minutes nonstress test(NST) and 10-minutes acoustic stimulation test (AST). Acoustic stimulations were performed using Fetal Acoustic Stimulator (Model 146, Corometrics, US). We analyzed the FHR response after acoustic stimulation using our on-line computerized FHR analysis system, HYFM-I & II software. The changes of loss of signal, baseline FHR, variability, number of fetal movements, and number of FHR accelerations were analyzed numerically. RESULT: The mean baseline FHR was increased in term pregnancies from 141+/-7.0bpm to 152.7+/-9.7bpm, and in preterm pregnancies from 144.6+/-6.8bpm to 156.8+/-10.2bpm, respectively. The mean baseline FHR was significantly increased in both term and preterm pregnancies (p<0.01. paired t-test). The variability of FHR was increased in term pregnancies from 18.2+/-6.4bpm to 22.6+/-5.0bpm and in preterm pregnancies from 17.8+/-5.5bpm to 22.7+/-5.9bpm, respectively. The variability of FHR was also significantly increased in both term and preterm pregnancies. (p<0.01. paired t-test) CONCLUSION: The mean baseline FHR and the variability of FHR was significantly increased both preterm and term pregnancies. But the difference of each FHR variables between preterm pregnancies and term pregnancies was not statistically significant in this study.

Relapsing polychondritis (RP) is rare, chronic, relapsing, and multisystemic inflammatory disease targeting the cartilaginous structures. Respiratory track involvement occurs in approximately half of the cases. Subglottic stenosis is a rare manifestation of RP. Here, we report a case of RP with a subglottic stenosis, resulting in acute respiratory failure. A 63-year old man was admitted complaining of multiple joint pain, general weakness, weight loss, throat pain, hoarseness, exertional dyspnea, and hearing difficulties. A laryngoscopy and neck CT revealed a subglottic stenosis. Four days after admission, he complained severe dyspnea resulting in acute respiratory failure. Immediately, a tracheostomy was done for airway preservation. After high dose steroid therapy, the general symptoms were improved. However, the subglottic stenosis was sustained. Thus, a laryngotracheal augumentation and stent insertion was performed. The speech valve was then replaced. The subglottic stenosis was managed with low dose steroid and monthly cyclophosphamide pulse therapy, and the patients has been followed up regularly.

OBJECTIVES: The trial was performed to obtain an unbiased comparison of the relative merits of endocervical and vaginal prostaglandin E2(PGE2) in the case of parous and nulliparous woman with favorable and unfavorable cervical features. This study was performed to determine the clinical usefullness of endocervical PGE2 comparing with the vaginal PGE2 in cervical ripening and induction of labor. METHOD: The randomized trial with 65 Participants was performed with sealed envelopes for parity and Bishop score (from March to september, 1998). PGE2 tablet(3mg Dinoprostone) was administrated intravaginally to the 32 pregnant women and endocervically to the 33 pregnant women every eight hours with maximum three times until the regular labor develped. RESULT: Outcomes of labor and delivery were clearly related to cervical score at trial entry. endocerval PGE2 had a more marked effect on cervical ripeness than did vaginal PGE2. There were no significant differences on age distribution, gestatioanal period, primiparity, cervical status, initial B-score in each group. There were no significant differences in cesarian section rate, fetal distress, uterine hyperstimulation, side effect and poor infant outcome between the groups The mean induction time was statistically shorter in cervical group with multiparous women than other group(p=0.0195). In the induction-active labor time, cervical with primi group was statistically shorter than other group(p=0.0245). Statistically significant differences were noted between the nulliparous woman and multiparous women in mean induction time, induction-active labor time, time to B-score 8. In the factor that effects induction-active labor, route was significantly better than other factor.(p=0.0001) CONCLUSION: edocervical PGE2 is more effctive than vaginal PGE2 in cervical ripening and induction of active labor. the endocervical PGE2 resulted in a significantly shorter induction to active labor time compared with vaginal PGE2 and has almost no side effect. Because differences in effectiveness between endocervical and vaginal PGE2 are marginal, preference of woman and clinicians can the choice between them.

Aneurysms of the posterior inferior cerebellar artery (PICA) are rarely encountered. In particular, due to frequent anatomic complexity and the presence of nearby critical structures, PICA origin aneurysms are difficult to treat. However, recent reports of anecdotal cases using advanced endovascular instruments and skills have made the results of endovascular treatment rather outstanding. PICA preservation is the key to a successful endovascular treatment, based on the premise that a PICA origin aneurysm is well occluded. To secure PICA flow, stenting into the PICA would be the best method, however, it is nearly impossible technically via the ipsilateral vertebral artery (VA) if the PICA arose at an acute angle from the sac. In such a case, a bilateral approach for stent-assisted coiling can be a creative method for achievement of two goals of both aneurysm occlusion and PICA preservation: ipsilateral approach for coil delivery and contralateral cross-over approach for stent delivery via a retrograde smooth path into the PICA.

BACKGROUND: Acinetobacter baumannii is a glucose-nonfermenting gram-negative rod and is a well-recognized nosocomial pathogen. In recent years, A. baumannii strains showing resistance to carbapenems by producing metallo-beta-lactamases or OXA-type beta-lactamases have increased, and it is considered to be a serious clinical problem. But genotypes of carbapenemases produced by A. baumannii isolates in Korea have been rarely reported. The purpose of this study was to investigate the prevalence of imipenem-resistant A. baumannii and to determine the mechanism of resistance. METHODS: During the period of January through September, 2003, susceptibilities to imipenem of A. baumannii isolates from patients admitted in Kosin University Gospel Hospital in Busan, Korea were investigated. The modified Hodge and EDTA-disk synergy tests were performed for screening of carbapenemase and metallo-beta-lactamase-production. Minimal inhibitory concentrations (MICs) were determined by the agar dilution method. For detection of IMP, VIM and OXA-type beta-lactamases genes, polymerase chain reactions (PCR) were performed, and the DNA sequences of OXA-type beta-lactamases genes were determined by using the dideoxy-chain termination method. The isoelectric points of beta-lactamases were determined by isoelectric focusing. Pulsed-field gel electrophresis (PFGE) of the SmaI-digested genomic DNA was performed. RESULTS: A total of 193 strains of A. baumannii were collected from patients during the surveillance period. Twenty-seven percents (52/193) of A. baumannii isolates were resistant to imipenem. Among the 52 imipenem-resistant isolates, 41 isolates (78.8%) showed positive results in the modified Hodge test, but none of the isolates showed positive results in the EDTA-disk synergy test. Thirty-eight modified Hodge test-positive isolates harbored blaOXA-23 gene, but none of the isolates harbored IMP- or VIM-type metallo-beta-lactamases genes. Analytical isoelectric focusing revealed that all the 38 isolates had a nitrocefin-positive band at pI of 6.65. Thirty-five OXA-23-producing isolatesshowed a similar PFGE pattern when digested by SmaI endonuclease. CONCLUSION: Thirty-eight clinical isolates of A. baumannii acquired resistance to imipenem by producing OXA-23 beta-lactamase. Among them were 35 isolates thought to be originated from the same source, because they contained a similar chromosomal type. To the best of our knowledge, this is the first time that OXA-23 beta-lactamase has been detected in Korea.

PURPOSE: Colistin resistance in Acinetobacter baumannii (A. baumannii) is mediated by a complete loss of lipopolysaccharide production via mutations in lpxA, lpxC, and lpxD gene or lipid A modifications via mutations in the pmrA and pmrB genes. However, the exact mechanism of therapy-induced colistin resistance in A. baumannii is not well understood. MATERIALS AND METHODS: We investigated the genotypic and phenotypic changes that underlie pan-drug resistance mechanisms by determining differences between the alterations in extensively drug-resistant (XDR) A. baumannii (AB001 and AB002) isolates and a pan-drug resistant (PDR) counterpart (AB003) recovered from one patient before and after antibiotic treatment, respectively. RESULTS: All three clinical isolates shared an identical sequence type (ST138), belonging to the global epidemic clone, clonal complex 92, and all produced OXA-23 carbapenemase. The PDR AB003 showed two genetic differences, acquisition of armA gene and an amino acid substitution (Glu229Asp) in pmrB gene, relative to XDR isolates. No mutations were detected in the pmrA, pmrC, lpxA, lpxC, or lpxD genes in all three isolates. In matrix-assisted laser desorption ionization-time of flight analysis, the three isolates commonly showed two major peaks at 1728 m/z and 1912 m/z, but peaks at 2034 m/z, 2157 m/z, 2261 m/z, and 2384 m/z were detected only in the PDR A. baumannii AB003 isolate. CONCLUSION: Our results show that changes in lipid A structure via a mutation in the pmrB gene and acquisition of armA gene might confer resistance to colistin and aminoglycosides to XDR A. baumannii strains, resulting in appearance of a PDR A. baumannii strain of ST138.

PURPOSE: Isolated noncompaction of the ventricular myocardium(INVM) can present as heart failure or arrhythmias in a child. It is a rare disorder, characterized by prominent trabecular meshwork and deep intertrabecular recesses. We still know little about the diagnosis, symptoms, and clinical outcomes of INVM. METHODS: We included in our study 6 patients who showed ventricular noncompaction on echocardiography. Patients were diagnosed as INVM were excessively prominent trabeculations with deep intertrabecular recesses were found on echocardiography. Patients who had other complex heart lesions such as pulmonary atresia with intact ventricular septum in addition to ventricular noncompaction, were excluded. RESULTS: Age at presentation ranged from 1 day 7 years, with follow up being as long as 6 years. Symptoms at initial presentation were heart murmur, paroxysmal supraventricular tachycardia, cyanosis, feeding intolerance, ventricular tachycardia, and cardiomegaly at fetal screening. Prominent trabeculations and intertrabecular recesses were observed at left ventricular apex in all six patients. All patients were alive at last follow-up. One patient showed WPW syndrome on electrocardiography. Echocardiography revealed decreased systolic function in 4 patients, and decreased systolic and diastolic function in 1 patient. One patient is currently asymptomatic. CONCLUSION: Six patients were diagnosed with INVM with various symptoms at initial presentation. Echocardiography is the most important tool in the diagnosis of INVM due to its morphological characteristics. INVM can rarely be the cause of long term systolic dysfunction, and early detection by echocardiographic screening may be beneficial.

Acute giant coronary aneurysm after Kawasaki disease (KD) is a catastrophic complication that can be fatal and very difficult to manage. However, no fixed consensus has been reached for the management of super-giant coronary aneurysms in the acute setting. Here, we report the successful management of young children with super-giant coronary aneurysms after KD. Based on our experience, hemodynamic stabilization to prevent further coronary dilation or rupture and strict anticoagulation to avoid thrombus formation are mandatory in the management of this condition.

Whereas stroke that is associated with the use of various street drugs has been frequently noted, cerebral infarction related to marijuana has been rarely reported. We experienced a 36 year-old male who developed sudden onset of dizziness and gait disturbance after marijuana smoking. On admission, neurological examination revealed right cerebellar dysfunction with prominent falling tendency to right side during tandem gait. Brain MRI showed high signal intensity on T2-weighted image on right posterior inferior cerebellar arterial (PICA) territory suggesting acute infarction. He had no risk factors for stroke except tobacco smoking and denied the use of other street drugs. Serologic work-up for coagulopathy and cardiologic evaluation were unremarkable. On cerebral angiogram, narrowing of proximal part of left PICA and diffusely spastic arterial changes of whole posterior circulation were revealed. On the basis of the physiologic effect of marijuana, we could infer that the probable mechanism of the stroke was intracerebral vasoconstriction or hemodymic change.
