BACKGROUND: We performed electrical cardioversion for the patients with chormic nonvalvular atrial fibrillation under the transesophageal echocardiographic guidance after anticoagulation to evaluate the safety of this procedure and the effects of electrical cardioversion on the atrial function. METHODS: After anticoagulation therapy with coumadine for three weeks, we tried chemical cardioversion with amiodarone first. Failed cases were included in this study. Pre-cardioversion transesophageal echocardiographic parameters were measured after exclusion of thrombi. After sedation with intravenous midazolam, direct-current cardioversion was done with the transesophageal echocardiographic probe in situ. Immediately after sinus conversion, we measured echocardiographic parameters again. Spontaneous echo contrast(SEC), left atrial appendage flow velocity, pulmonary vein flow velocity and time-velocity-integral(TVI), transmitral flow velocity, TVI and deceleration time were measured. All patients were anticoagulated for at least 4 weeks after cardiovesion. RESULTS: The total number of patients was forty one(24 males, 17 females) with the mean age of 58 years(range : 39-70). Mean duration of atrial fibrillation was 65 months(range : 1-360). Hypertension(12), dilated cardiomyopathy(10), cerebrovascular accidents(6), ischemic heart disease(2) and chronic lung disease(1) were associated. There were no complications. SEC increased or newly appeared in 18(43.9%) patients after sinus conversion. The left atrial appendage emptying velocity decreased(32.8+/-17.4 vs. 22.1+/-11.4cm/sec, p=0.020) and systolic TVI of both upper pulmonic vein increased significantly after sinus conversion. In two cases, early systolic forward flow(S1) of pulmonic vein appeared after sinus conversion. Transmitral E velocity decreased(86.9+/-28.8 vs. 76.3+/-30.6cm/sec, p=0.006) and the deceleration time increased(164+/-49 vs. 206+/-53msec, p=0.000) after sinus conversion. Transmitral A velocity was still low(34.9+/-19.5cm/sec) and E/A ratio was high(2.6+/-1.4) immediately after sinus conversion. CONCLUSION: After appropriate anticoagulation therapy and exclusion of left atrium and left atrial appindage thrombi with TEE we could perform electrical cardioversion safety without complications. The changes in transesophageal echocardiographic parameters after sinus conversion revealed the appearance of atrial mechanical activity in concordance with electrical activity. But these findings suggested atrial stunning or electromechanical dissociation which necessitates extended anticoagulation therapy until the full recovery of atrial mechanical function.

Tarsometatarsal injury has not been paid much attention due to it is unusual frequency. But the cases of tarsometatarsal injuries are on the increase in proportion to the increasing "high energy trauma injury" resulted from the traffic and industrial accidents. The purpose of this study is both assessing the relative effects among clinical results, final radiologic findings, treatment results and symtoms. In view of the results so far achieved from 20 cases of tarsometatarsal fracture dislocation which had been treated at Sung-Ae general hospital from January 1990 to December 1993, the results were as follows: 1. Thirteen cases were treated by open reduction and 3 cases were treated by closed reduction with smooth pins but no reduction loss were experienced. 2. Traumatic arthrosis could be observed in 14 cases but there were no influences on the functional end results. 3. Anatomical results correlated with pain. 4. Anatomical or neraly anatomical reduction was considered as most important factor of prognosis.

Objectives: Alzheimer’s disease, a pervasive neurodegenerative disorder with global implications, links oral health conditions, such as edentulism and periodontitis, to cognitive impairment. This study aimed to objectively assess the oral health of 1,456 patients with dementia using panoramic imaging and explore potential associations between general health and anthropometric measurements. Methods: Patients’ panoramic images documented at Seoul St. Mary’s Hospital and Eunpyeong St. Mary’s Hospital during 2011-2020 were retrospectively scrutinized for oral health parameters. Data on general health, anthropometrics, and body mass index (BMI) were collected. The patients were categorized according to their remaining teeth, dental caries, presence of periodontitis, and BMI. Results: The average age was 74.20 years, and the average teeth number was 20.67. Significant differences in dental caries and periodontitis rates were observed across BMI categories. Younger age and female sex correlated with improved oral health. The underweight BMI group exhibited higher caries rates, whereas the average BMI group showed favorable outcomes for both caries and periodontitis. Conclusions Comprehensive analysis including panoramic imaging revealed notable associations between oral health and BMI in patients with dementia, emphasizing the importance of regular dental checkups. This study underscores the potential links between oral health and systemic conditions in dementia, necessitating further research to elucidate causal relationships and mechanisms.

Objectives: There was no previous report about the electrical cardioversion for the patients with atrial fibrillation after successful percutaneous ballon mitral valvuloplasty (PBMV). We performed electrical cardioversion after PBMV to evaluate the effectiveness of this procedure in the view of conversion to and maintenance of the sinus rhythm. METHODS: 28 patients who had persistent atrial fibrillation after successful PBMV were included in this study. All patients were anticoagulated with warfarin. Amiodarone was loaded and maintained before cardioversion. The PBMV procedures were guided by transesophageal echocardiography in all patients. Transthoracic echocardiography was done before and after PBMV and cardioversion, and was followed. RESULTS: The number of patients were 28 (male 9 and female 19) within the mean age of 50.3+/-12.0 years (24-66). Initially 24 patients (86%) succeeded in electrical cardioversion. The energy required for successful conversion was 230+/-75J, on average. There were no complications except for the transient sinus bradycardia in 2 cases. The mean follow-up duration was 357+/-144 days and when followed-up, the sinus rhythm was maintained in 15 patients out of 24 with initial success (63%). No factor was significantly related to the success of cardioversion, but left atrial dimension after 1 month of PBMV was significantly related to the maintenance of the sinus rhythm. CONCLUSIONS: This study suggests that electrical cardioversion of atrial fibrillation after successful PBMV is favorable and recommendable treatment modality of chronic valvular atrial fibrillation with high conversion rate (88%) and good maintenance rate (63%).

With the methods of restriction fragment length polymorphisms(RFLPs) and Southern blot, we performed a molecular genetic study in 20 cases of intracranial meningiomas. There were four cases of invasive meningiomas, two cases of recurrent meningiomas and one case of central neurofibromatsis. Comparison of the alleles detected by DNA probes in normal versus tumor DNA revealed chromosomal alteration. The following probes were used : ESR(chromosome 6q), pYN22, pYNH37.3(chromosome 17p), cEFD52(chromosome 17q), D22S10, IGLC2(chromosome 22q). In seventeen of 20 cases(85%), constitutional heterozygosity was observed for IGLC2 probe on chromosome 22q and loss of heterozygosity was detected in nine of 17 informative cases(53%). There was no loss of heterozygosity for other probes. Three of 4 cases of invasive meningiomas and one case of central neruofibromatosis displayed loss of heterozygosity.

The occurrence of internal hernia through a defect in the broad ligament is a very rare condition, which may cause small bowel obstruction. This is a case of a 50-year-old woman who developed intestinal obstruction induced by internal hernia and who had undergone laparoscopic myomectomy 7 years prior to visiting our emergency room. Abdominopelvic computed tomography showed luminal narrowing of the ileum and dilatation of the pelvic loop of the small bowel at the left side of the uterus. We detected internal hernia through the defect in the broad ligament and managed it successfully by performing a laparoscopic procedure using a barbed suture, V-Loc (Covidien, Mansfield, MA).
