Pneumomediastinum is a relatively uncommon, infrequently reported entity, In the evaluation of these entity, it is important to exclude pathological causes, including Boerhaave's syndrome which carries a high mortality. Spontaneous pneumomediastinum is related to excessive intraalveolar pressure leading to rupture of perivascular alveoli in the setting of a Valsalva maneuver without communication to gut material. So, it has a benign self-limited course and rarely requires medical intervention. On the contrary, secondary pneumomediastinum caused by instrumental, traumatic, and spontaneous perforation of esophagus. Although the prognosis have been improved since the advent of broad-spectrum antibiotics and nutritional support, pneumomediastinum due to esophageal perforation still has a high morbidity and mortality. The most important prognostic factor is the time interval between perforation and initiation of therapy, and an awareness and a high clinical suspicion is critical in the early diagnosis and treatment. Recently, we have experienced 2 cases of pneumomediastinum, one case was spontaneous pneumomediastinum and the other may be caused by instrumental esophageal perforation. We report the clinical course of the patients with a current literature review.

Nowadays shoulder ultrasound is commonly used in the assessment of shoulder diseases and is as accurate as magnetic resonance imaging in the detection of several pathologies. Operator dependence is the main disadvantage of shoulder ultrasound. After adhering to a strict examination protocol, good knowledge of normal anatomy and pathologic processes and an awareness of common pitfalls, it can be used as a focused examination providing rapid, real-time diagnosis, and treatment by ultrasound-guided interventions in desired clinical situations. Also shoulder ultrasound can help the surgeon decide whether treatment will be surgical or nonsurgical. If arthroscopy is planned, sonographic findings help to counsel patients regarding surgical and functional outcomes. If a nonsurgical approach is indicated, ultrasound can be used to follow patients. This review article presents the examination techniques, the normal sonographic appearances and the main pathologic conditions found in shoulder ultrasound. And also addresses a simplified approach to scanning and ultrasound-guided intervention. Knowledge of optimal techniques, normal anatomy, dynamic maneuvers, and pathologic conditions is essential for optimal performance and interpretation of images.

PURPOSE: The diagnosis of Budd-Chiari syndrome on CT is difficult if CT do not demonstrate obstruction of the IVC or hepatic vein and other parameter is needed for the correct diagnosis. The purpose of our study was to determine the usefulness of measuring the diameter of azygos-hemiazygos vein on CT to differentiate Budd-Chiari syndrome from advanced liver cirrhosis. MATERIALS AND METHODS: Fourteen patients who were proven as Budd-Chiari syndrome on vena cavography were studied for analysis. All patients showed evidence of liver cirrhosis on CT. As a control group fifteen cases of advanced liver cirrhosis who underwent endoscopic sclerotheraphy due to esophageal variceal bleeding were also included for comparison. The largest short axis diameter of azygos-hemiazygos vein was measured in all patients at the level of diaphragm on axial CT and the results were compared in both groups. RESULTS: In patients with Budd-Chiari syndrome the largest short axial diameter of azygos-hemiazygos vein ranged from 0.5cm to 2.5cm(mean ;1.5cm). Only one patient who showed hepatic venous obstruction demonstrated a diameter of less than 1 cm(0. Scm). In contrast, the diameter in patients with advanced liver cirrhosis without obstruction of IVC or hepatic vein was less than 1 cm with a range from 0.2cm to 1 cm(mean ;0.6cm). CONCLUSION: The short axis diameter of azygos-hemiazygos vein was an indicator of IVC obstruction (Budd-Chiari syndrome).

BACKGROUND: Bupivacaine is a potent, and commonly used, long acting local anesthetic. If accidentally injected into the systemic circulation, bupivacaine can cause lethal dysrhythmias and circulatory collapse. Attempts to treat bupivacaine induced cardiac toxicity have been varied and controversial, and they have not been very successful. The aim of this study was to investigate the electrophysiologic effects of bupivacaine in Purkinje fibers. METHODS: Effects of bupivacaine on the membrane potential were studied in 12 isolated canine Purkinje fibers. Purkinje fibers from ventricle were dissected and mounted in a tissue chamber perfused with Tyrode's solution. Transmembrane potentials recorded through glass microelectrodes filled with 3M KCI in the beating or quiescent Purkinje fibers during infusions of bupivacaine at concentratons of 3*10/-7M,10/-6M, 3*10/-6M,10/-5M, and 3*10/-5M. RESULTS: Bupivacaine reduced action potential druation in a dose-dependent manner. Bupivacaine produced a decrease in intracelullar sodium ion activity in driven(1Hz) and quiescent canine Purkinje fibers. Bupivacaine-induced hyperpolarizaton of diastolic membrane potential in quiescent Purkinje fibers was dose dependent, and the hyperpolarization by bupivacaine was attenuated by depolarization induced by high potassium extracellular concentration in part. CONCLUSIONS: These results suggest that bupivacaine decreases the fast inward sodium current, and inhibits pacemaker current in canine Purkinje fibers.

Since the introduction of Holdsworth's new classification on fracture-dislocations of spine with particular emphasis on the role of posterior ligmaent complex, operative reduction and spinal fusion is considered to be an established procedure in treating unstable injuries of the thoracolumbar spine.By stabilizing unstable fractures,nursing, and rehabilitation become much easier. Among the various methods and devices, Harrington instrumentation and posterior spinal fusion have been used and found to be acceptable in our series. Twenty five consecutive patients with unstable fractures and fracture-dislocations' of thoracolumbar spine were treated by open reduction and spinal fusion with Harrington rod fixation at the Department of Orthopedic Surgery, Kang Nam General Hospital Public Corporation from the period of 1982 to 1985. The following results were obtained from analysis of the cases. l. Among 25 cases, 15 (60%) were due to flexion-rotation violence, 5 pure flexion,3 vertical compression, 1 shear fracture respectively. 2. Among 16 cases with neurologic deficit, 15 cases showed considerabel improvement after surgery. 3. Most of the cases showed satisfactory bony fusion, and average postoperative kyphotic angle was 14.4 after 3 months. 4. Although no particular external fixation was adopted, permitting mobility in bed, postoperative correction was relatively well maintained.

PURPOSE: To evaluate the objective difference of the shoulder position during ultrasound examination regarding diagnostic value for shoulder lesion, view range and visibility. MATERIALS AND METHODS: A prospective study was performed enrolling 312 patients who underwent diagnostic ultrasonography due to shoulder pain between January 2016 and June 2016. Examination was performed by a single orthopaedic surgeon with 5 years of musculoskeletal ultrasonography experience. Images of the longitudinal and transverse plane of the supraspinatus tendon and the nearby soft tissues (subscapularis and biceps long head tendon, subdeltoid bursa, etc.) were obtained in the three different positions, shoulder extension, modified Crass, and Crass position. The correlation between the demographic data (age, sex and body mass index) and the visual analogue scale (VAS) of the affected shoulder & the capable shoulder position was analyzed. Another orthopaedic independently measured the size of the tear and using classified the image visibility of the supraspinatus, subscapularis, and biceps long head tendon on the short-axis view from the rotator interval into I to III and X. RESULTS: Of the 312 patients, 126 were excluded and total of 186 cases were included in this study. None of the demographic data were related to the possible arm position. However, VAS for pain was the only factor related with the number of possible arm positions during sonography. Kappa agreements for the diagnosis were mostly high of over 0.90. Grades of the short-axis view from the rotator interval in each position were mostly grade II or grade III, which refers to that the anterior portion of supraspinatus tendon, which is the most fragile portion to the tear and it was well-defined regardless of the arm position. The average longitudinal tear sizes were 1.48, 1.52, and 1.61 cm in the shoulder extension, modified Crass (Middleton), and Crass position, respectively. CONCLUSION: Shoulder extension position during ultrasonography examination of shoulder shows similar diagnosis rate of supraspinatus tendon tear or calcific tendinitis compared to modified Crass (Middleton) or Crass position, the two well-known standard positions. It is also a useful position for patients who suffer with severe shoulder pain.
