In the past decades there has been a growth of interest in the use of stellate ganglion block (SGB) as part of the diagnosis and therapy for the disease of the head, neck and upper extremities. For the evaluation of changes in hemodynamics and temperature of the affected extremity after the SGB, unilateral SGB (either right or left) was performed by local injection of 10 ml of 1% lidocaine without epinephrine in 45 patients (right side SGB: 25, left side SGB: 20) with various diseases. Systolic and diastolic blood pressure, pulse rate and skin temperature of the ipsilateral hand were studied before and 1, 2, 3, 4, 5, 10, 15, 30 and 60 minutes after the block. The results were as follows: 1) Changes of blood pressure: Systolic and distolic blood pressure after either right or left side SGB showed no statistically significant change. 2) Changes of pulse rate: While the left side SGB showed a mild decrease without statistical significance, the right side SGB showed a statistically significant decrease at 30 and 60 minutes after the block (p<0.05). 3) Changes of skin temperature of the blocked hand: Either side SGB produced a gradual increase in temperature with time and showed statistical significance from 10 minutes in the left side block (p<0.01), and a from 10 minutes after the block in the right side (p<0.01). Both sides SGB showed a maximal increase at 30 minutes after the block and a small decrease at 60 minutes after the block compared to the 30 minutes value. 4) Despite the successful SGB. 4 of 45 patients failed to produce a significant increase in skin temperature on the affected upper extremity. In conclusion, unilateral SGB with 1% lidocaine at the 6th cervical vertebral level is a safe method for use on an outpatient basis, and an increase in skin temperature in the affected upper extremity is necessary to confirm the successful therapeutic effect on disease of the upper extremity.

This study was carried out to observe the direct effect of hydrocortisone on renal function by infusing it into a renal artery. Hydrocortisone (5mg/kg) or saline (0.5 ml/kg) was infused directly into the left renal artery of the rabbit, the right kidney was left intact to serve as a control for general action of acetazolamide (10 mg/kg) or aminophylline (10 mg/kg), which was administered intravenously 30 minutes after the direct infusion of pretreated drugs (hydrocortisone or saline). The changes of urine volume, pH, urinary excretion rates of $Na^+,\;K^+\;and\;Cl^-$, and the clearances of inulin and PAH were measured at an interval of 10 minutes for half an hour after the direct infusion of hydrocortisone or saline, and for one hour after intravenous administration of acetazolamide or aminophylline. The results of the experiment were as follows: 1. Significant changes in urine volume and urinary electrolytes (excreted rates of $Na^+,\;K^+\;and\;Cl^-$) were observed in the hydrocortisone-infused group 10 minutes after the administration of acetazolamide, compared with the saline-infused group. Especially, the effect was more potent on the infused (left) side than on the contralateral (right) side. 2. Significant changes in urine volume and urinary electrolytes were also observed in all the aminophylline-treated groups, but no remarkable difference was noticed between the hydrocortisone-infused group and the saline-infused group, nor between the left and right sides. 3. No signicant changes in the clearances of inulin and PAH were in the infused (left) side of all the experimental groups, as compared with the contralateral (right) side. From the above results, it is obvious that hydrocortisone infused into a renal artery exerts diuretic action when administered in combination with acetazolamide, and the mechanism of action rests not on its hemodynamic change for renal blood flow, but on the potentiation of carbonic anhydrase inhibiting action. However, the exact mode of action remains yet to be clarified.

This study was performed to investigate the factor that might affect mandibualr body rotation. For the study, 115 patients with temporomandibular disorders and 35 dental students without angy signs and symptoms of temporomandibular disorders were randomly selected as the patient group and the contreol group, respectively. Preferred chewing side, Angle' classification, lateral guidance pattern, and affected side were clinically recorded, and the amount of Mandibular body rotational torque movement was measured in wide opening and closure, in right and left excursion with vertical and lateral distance in frontal plane, right and left rotational angel in horizontal and in frontal plane. Masticatory muscle activity of anteriorocclusal contact pattern on maximal hard biting were also observed synchronously with BioEMG and T-Scan , respectively. The observed items were muscle activity of anterior temporalis and superficial masseter, and tooth contact status related to contact number, force, duration, and occlusal unbalance between right and left arch. The data collected were analyzed by SAS statistical program. The results of this study were as follows : 1. Mean value of vertical distance in frontal plane in wide opening and closure was more in control subjects than in patients, but there was no difference for rotational angle. In right excursion, rotational angles were greater in patient group than in control group. 2. Comparison among the subjects by preferred chewing side did not reveal any significant difference, but comparison among patients by affected side showed more rotational amount in bilaterally affected patients than in unilaterally affected patients. 3. Comparison among the subjects by Angle's classification or lateral guidance pattern revealed no difference. There was also no difference between preferred chewing side and contralateral side, and between affected side and contralateral side. 4. Positive correlation in madibular rotational torque movements were observed among vertical distance, total horizontal rotation angle, electromyographic activity of anterior temporalis, tooth contact number, and tooth contact force but total frontal rotation angle almost did not show any correlation with other variables except vertical distance.

Purpose: The authors measured the anteversion of the femoral neck and acetabulum and the sum of the two values in normal Korean people by computed tomography. The authors examined the normal range of the values to analyze the difference in sex and sides as well as the relationship between the femoral neck and acetabular anteversion. Materials and Methods: The authors measured the anteversion of the femoral neck and acetabulum in 118 normal Korean adult males and 114 females aged between 21 and 49 on both the right and left sides by computed tomography and calculated the sum of anteversion. The authors analyzed the mean and standard deviation, and investigated the sex differences and side differences, as well as the relationship between the acetabular anteversion and femoral neck anteversion statistically. Results: The anteversion of the acetabulum in males was 15.3°±6.1° on the right side and 15.3°±6.6° on the left side. The anteversion of the femoral neck in males was 5.3°±7.6° on the right side and 1.5°±9.2° on the left side according to the Hernandez et al. method. The anteversion of acetabulum in females was 16.8°±5.4° on the right side and 16.3°±5.8° on the left side. The anteversion of femoral neck in females was 10.3°±8.2° on the right side and 7.9°±8.2° on the left side according to Hernandez et al. method. No difference in acetabular anteversion, and a significant difference in the femoral neck anteversion on both the right and left sides were observed between males and females. No difference of acetabular anteversion was observed between the right and left sides, but a significant difference in femoral neck anteversion was noted between the right and left sides measured by either the Hernandez et al. method or Weiner et al. method. The Pearson coefficient revealed no correlation between the femoral neck anteversion and acetabular anteversion. Conclusion: No difference in the acetabular anteversion was observed, but there was a significant difference in femoral neck anteversion between males and females. A significant difference in femoral neck anteversion was observed between the right and left sides. No correlation was noted between the anteversion of the femoral neck and acetabulum.

Unilateral vocal cord palsy which is associated with laryngeal trauma is not uncommon event. In a 42-year-old male, a cricoid cartilage fracure had been developed after blunt trauma. The endoscopic findings showed contusion and diffuse swelling around the left arytenoid and false cord. During phonation, the mobility of left side true vocal cord was decreased. There were no level difference and displacement of the left side arytenoid. We used the laryngeal electromyography (LEMG) to make a differential diagnosis between the cricoarytenoid joint dislocation and the injury of recurrent laryngeal nerve. At the right thyroarytenoid muscle and cricothyroid muscle, the findings of LEMG were normal. But the amplitude and frequency during phonation were decreased (partial denervation) at the left thyroarytenoid muscle. LEMG is a very useful method to predict the diagnosis of vocal cord palsy.

The juxtaposition of atrial appendage may possibly be diagnosed by angiography recently, and it is widely regarded as an ominous sign of severe cyanotic congenital heart disease. However, it is apparently rare congenital cardiac anomaly in which the atrial appendages lie side by side, both to the left or right of the great arteries, known as left or right juxtaposition of the atrial appendages. Juxtaposition of the atrial appendages has no functional significance, since it does not, itself, cause any hemodynamic disturbance. But it`s presence always indicates the coexistence of other major cardiac anomalies. In review of literatures TGA and VSD are invariable present, and ASD is common. Other anomalies, such as, tricuspid atresia, pulmonary outflow that, obstruction bicuspid pulmonic valve, persistent SVC etc. are relatively high incidence. In this report, we present one case of 6 year old female child having left juxtaposition of atrial appendage combined with TGA [D-looping, D-transposition], TAPVD, large ASD, small VSD, and vertical vein.

Preoperative surgical simulation in orthognathic surgery has progressed in recent years; the movement of the mandible can be anticipated through three-dimensional (3D) simulation surgery before the actual procedure. In this case report, the mandible was moved to the intended postoperative occlusion through preoperative surgical 3D simulation. Right-side condylar movement change was very slight in the surgical simulation, suggesting the possibility of mandibular surgery that included only left-side ramal osteotomy. This case report describes a patient with a mild asymmetric facial profile in which the mandibular menton had been deviated to the right and the lips canted down to the left. Before surgery, three-dimensional surgical simulation was used to evaluate and confirm a position for the condyle as well as the symmetrical postoperative state of the face. Facial asymmetry was resolved with minimal surgical treatment through unilateral intraoral vertical ramus osteotomy on the left side of the mandible. It would be a valuable complement for the reduction of the surgical treatment if one could decide with good predictability when an isolated intraoral vertical ramus osteotomy can be done without a compensatory osteotomy on the contralateral side.

Purpose : This study investigated the effects of different types of plank exercise on abdominal muscle thickness in subjects with asymmetric pelvic anterior tilt. Methods : Participants with a diagnosis of pelvic anterior tilt were divided into an experimental group (n=12) and a control group (n=13). The thicknesses of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles were measured using an ultrasound diagnostic apparatus. The data were analyzed using an SPSS (Ver. 21) program. Results : In the experimental group, there was a significant difference in the thicknesses of the left and right muscles in the standing and elbow plank exercises (p<.05). All the muscle thicknesses increased significantly during the plank exercises(elbow plank, right-side plank, and left-side plank) as compared with those in the standing position (p<.05). In addition, the side-plank exercise resulted in significantly higher muscle thickness of the supported side (p<.01, p<.001). Conclusion : These findings suggest that asymmetric exercise should be applied to the change of the left and right muscles of the abdominal when applying plank exercise according to pelvic anterior tilt.

Purpose: After surgical interventions of mandible fractures, facial asymmetry can be occurred, and it leads to serious problems for patients. This can be solved by mandible angle ostectomy. Methods: A 19-year-old male underwent percutaneous surgical intervention for left mandibular angle and right parasymphyseal fractures 3.5 years ago. The left angle was protruded compared to the other side. Using a percutaneous approach, $4.5{\times}1cm$ sized piece of mandible angle was sawed off. For the right angle, intraoral approach was performed for angle ostectomy, and the angle was sawed off by a size of $4{\times}1cm$, using a pattern based on the piece from the left side. Results: After surgery, no complications such as subcondylar fractures, refractures, insufficient corrections, secondary angle formations, hematomas, and transient nerve palsies were seen, and symmetric correction of mandible angles were done. Conclusion: In facial asymmetries due to mandibular fractures, mandible ostectomy could be a solution. Using the bone section from the contralateral side, measurement of the amount of bone sawed off was possible, and via percutaneous approach on the previously operated site with simultaneous scar revision, and intraoral approach for the contralateral side, cosmetically satisfactory result was obtained.
