Clinical Factors Affecting the Results of Regenerative Endodontic Procedure / 대한소아치과학회지

This study retrospectively analyzed the effect of clinical factors on the outcomes of REP(regenerative endodontic procedure). Patients who received the REP using triple antibiotic paste due to trauma or fracture of dens evaginatus from February, 2011 to January, 2020 were included in the study. Finally, 57 teeth in 54 patients were selected.Investigated clinical factors were as follows: intentional bleeding, etiology, and root development stage. Treatment outcomes evaluated were as follows: improvement of subjective symptoms, changes in the periapical lesion, and the amounts of root development after REP. To compensate for differences in angulation and position between repeated radiographic examinations, images were aligned by Turboreg plugin. To evaluate the amounts of root development, apical diameter, root area, and root length were measured by ImageJ software.Among the aforementioned factors, intentional bleeding had no significant effect on treatment results. Regarding the etiology, the increase in the root area and the root length was significantly less in trauma cases than in dens evaginatus fracture cases. Considering root development stage, more immature teeth presented more increase in the root area.

Anesthetic experience of a patient with relapsing polychondritis: A case report / 대한마취과학회지

Relapsing polychondritis is a rare disease characterized by progressive inflammation and destruction of cartilaginous structures such as ears, nose, and tracheolaryngeal structures. As a result, tracheolaryngeal involvement makes anesthetic management a challenge. Anesthetic management of a patient with relapsing polychondritis may encounter airway problems caused by severe tracheal stenosis. We present the case of a 60-year-old woman with relapsing polychondritis who underwent wedge resection of the stomach under epidural analgesia. Thoracic epidural blockade of the T4-10 dermatome was achieved by epidural injection of 7 ml of 0.75% ropivacaine and 50 microg of fentanyl. The patient was tolerable during the operation. We suggest that epidural analgesia may be an alternative to general anesthesia for patients with relapsing polychondritis undergoing upper abdominal surgery.

Pulsed Radiofrequency Treatment of Pain Relieving Point in a Soft Tissue

Pulsed radiofrequency (PRF) treatment of nervous tissue has been proposed as a less neurodestructive technique alternative to continuous RF heat lesioning. Recently, clinical reports using PRF have shown favorable effects in the treatment of a variety of focal pain areas, even in non-nervous tissues; however, the mechanism of effect underlying this treatment to non-nervous tissue remains unclear. We report the case of a 67-year-old male who presented with pain reliving point in the posterior neck. The patient had pain in the posterior neck for 3 years. The pain subsided with pressure applied to a point in the posterior neck. There were no specific abnormal findings on laboratory testing and radiologic examinations. After PRF treatment to the pain-relieving point, he had pain relief which lasted more than 5 months.

Respiratory Compensation Thresholds in Healthy Korean Adults / 대한내과학회지

OBJECTIVES: The respiratory compensation threshold(RCT) is thought to be one of parameters by some for the evaluation of physical performance despite its controversial status. The purpose of this investigation is to establish the reference values of the RCT in healthy Korean adults, and to examine the usefulness of this parameter in evaluating physical performance. METHODS: Symptom-limited maximal exercise test by Bruce protocol was carried out, and RCT and AT were determined by the aid of the computerized V-slope method, along with the VO2 max, in 441 healthy Korean adults consisting of 284 men and 157 women aged from 20`s to 60`s. In addition, correlation between RCT and AT was observed, and regression equations of the RCT were also derived. RESULTS: The RCT VO2 was tended to decrease with age in men, but not in women and the RCT VO2 of women was 26-30% less than that of men. The ratio of RCT VO2 to VO2 max (RCT VO2/VO2 max) was tended to increase with age and the RCT V was significantly correlated with AT VC4 and VO2 max in both sexes. CONCLUSION: Our study reveals that the RCT is another useful submaximal index along with the AT in evaluating physical performance. The regression equation of the RCT was RCT VO2(L/min)=1.4232-0.0102 A(age in year)+0.0204 W(weight in kg)-0.4889 S (sex, coded O for males and 1 for females).

A Case of Double Pylorus / 대한소화기내시경학회지

The double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb. Some investigators postulate that the doubling of the pyloric channel is a congenital phenornenon, but others believe that it is an acquired lesion. A 72 year-old-man was admitted to this hospital because of epigastric pain for 1 month. Upper G-I series revealed thickened rnucosal folds of pylorus and duodenal bulb and dilated, deformed duodenal bulb filled with barium materials. Endoscopic findings also showed two ovoid large openings of the pyloric channel divided by smooth thickened septum and multiple gastroduodenal ulcers. We thought that this case was an acquired lesion. The relevant literatures on the subject were reviewed.

Treatment of the tibia shaft fractures with ender nails / 영남의대학술지

Fractures of the tibial shaft are the most common among the long bone fractures, and have much difficulty in treatment due to their numerous complications. Thirty patients with fractures of the tibial shaft were treated with Ender nails under the image intensifier at the Department of Orthopedic Surgery, Yeungnam University Hospital from December 1986 to November 1991. The following results were observed. 1. The average age was 37.3 years and the number of male was three times of the female. The most common cause was traffic accident. 2. Twenty cases out of thirty one were closed fracture and the remaining 11 were open. The comminuted and segmental fractures were 18 (57.7%) in number and the most common fracture site was the middle one third (53%). 3. Average interval from injury to operation was 7.6 days and 19 cases showed associated injuries. 4. The mean duration of the bone union was 18.9 weeks and 2 cases showed the delayed union. 5. Twelve complications were noted such as shortening, varus deformity, delayed union, ankle motion limitation, nail irritation, and soft tissue infection.
