Clinical and radiological outcomes of ultrasound-guided barbotage using a spinal needle and subacromial steroid injection for calcific tendinitis of the shoulder

Methods@#Thirty-six patients with calcific tendinitis of the shoulder treated by US-guided barbotage with a spinal needle and subacromial steroid injection were included in the study. We evaluated clinical outcomes based on American Shoulder and Elbow Surgeons (ASES) score, Constant score, and visual analog scale (VAS) for pain score. Radiological outcomes were assessed by X-ray imaging at each visit. @*Results@#Our results showed that US-guided barbotage and subacromial steroid injection produced good clinical and radiological outcomes in patients with calcific tendinitis of the shoulder. Of the 36 patients, only one required surgical treatment, while the others showed improvement without any complications. Compared to values before the procedure, calcific deposit size and VAS, ASES, and Constant scores showed significant improvement 6 weeks after the procedure. No significant correlation was found between the initial calcific deposit size and clinical outcomes at each time point. @*Conclusions@#In patients with calcific tendinitis of the shoulder, US-guided barbotage using a spinal needle and subacromial steroid injection can yield satisfactory clinical and radiological results.

Comparison of In Vivo Three-Dimensional Glenohumeral Positions and Scapular Kinematics between Young and Older Male Groups

Background@#Many researchers have questioned whether shoulder kinematics such as the glenohumeral position and scapular kinematics would be different in different age groups. However, studies comparing shoulder kinematics between different age groups have been rare. The aim of this study was to analyze and compare the three-dimensional (3D) glenohumeral position, scapular kinematics, and scapulohumeral rhythm (SHR) during scapular plane arm abduction between a normal young male group and a normal older male group. @*Methods@#Twenty normal men (10 young and 10 older) were enrolled in this controlled laboratory study. Fluoroscopic images were obtained using a single plane X-ray system. Bilateral computed tomography scans were taken to create a 3D model. A 3D-2D registration technique was used to determine the 3D position and orientation of the bones of the shoulder. @*Results@#During scapular plane arm abduction, there were significant differences in scapular kinematics between the groups. The older male group showed more upward rotation, posterior tilt, and external rotation than the young male group. On the other hand, the glenohumeral position such as superior inferior translation, anterior posterior translation, and external rotation of the humeral head did not show significant difference between the groups. The mean value of SHR for the overall arm elevation range from start to maximum elevation angle for the older group and young group was 2.298 ± 0.964 and 2.622 ± 0.931, respectively, showing a significant difference between the two groups (p = 0.035). @*Conclusions@#Scapular kinematics and SHR were significantly different between the older male group and the young male group. Our study could provide reference values of shoulder kinematics for older men aged 55–65 years.

Use of Three-dimensional Transesophageal Echocardiography for the Chiari Network / 고신대학교의과대학학술지

The Chiari network is an embryonic remnant of the sinus venosus valve, which is characterized by a fenestrated, netlike structure in the right atrium and has the potential to be misdiagnosed as another right atrial pathology. Additionally, the Chiari network has been frequently reported to entrap intracardiac devices during surgical procedures. In this case report, we present two patients with a Chiari network confirmed by three-dimensional transesophageal echocardiography, which assisted in preventing device entrapment during intracardiac procedures.

The Change of Lung Volume after Uvulopalatopharyngoplasty in Obstructive Sleep Apnea Patients / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The objective of this research was to study the change of lung volume after uvulopalatopharyngoplasty (UPPP) in obstructive sleep apnea (OSA) patients. MATERIALS AND METHOD: Eight OSA patients were participated in this study. These patients were treated with UPPP at Seoul adventist hospital. Vital capacity (VC), inspiratory capacity (IC), expiratory residual volume (ERV) and FEV1, FEV1/FVC, FEV25-75% were determined by standard spirometry at the preoperative, at 3 postoperative days and 1 postoperative month. RESULTS: Vital capacity (VC) was significantly larger at 3 post-operative days (3.58+/-0.87 L, mean+/-SD) than those at pre-operative (3.12+/-0.69 L, mean+/-SD) in the patient with OSA (p=0.047). FEV 1 (L) was larger at 3 post-operative days (2.91+/-0.76 L, mean+/-vSD) than those at pre-operative (2.68+/-0.85 L, mean+/-vSD), but was not significantly correlated statically (p=0.249). CONCLUSION: We found significant correlation between preopeative and postoperative VC, IC.

A Case of Aneurysmal Bone Cyst in the Skull Base / 대한이비인후과학회지

Aneurysmal bone cyst is relatively rare, benign tumor in the adolescent. An aneurymal bone cyst in the skull base is much more rare. This lesion is frequently accompanied with other conditions such as fibrous dysplasia, osteosarcoma, and chondroblastoma. The differential diagnosis is important;however it is difficult to make a correct diagnosis. The diagnosis is usually made from CT and pathological findings such as multi-lobulated, thin-walled cyst filled with blood. The treatment of choice is complete excision, if possible. We experienced a case of aneurysmal bone cyst arising from petrous bone, which was treated with transtemporal approach with partial excision. The patient remains free of symptom for 24 months with some tumor remaining in the clival area.

The Effect of Dexamethasone in Tonsillectomy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Tonsillectomy is a very common surgical procedure in otolaryngology. Steroid is often given to decrease postoperative morbidity from the procedure. This study was designed to determine the intraoperative and postoperative efficacy of the intravenous administration of dexamethasone sodium phosphate, the long-acting steroid, before or after tonsillectomy. MATERIALS AND METHODS: Sixty children aged between 3 to 15 years were divided into three groups. Twenty children received intravenous dexamethasone sodium phosphate (1 mg/kg up to 15 mg) before undergoing sharp dissection tonsillectomy (group I). Another twenty children received it after operation (group II). The third group was control and did not receive the intravenous dexamethasone sodium phosphate (group III). Intraoperatively blood loss, surgical and anesthesia time were checked. After the operation, each child was evaluated for pain, oral intake, vomiting, body temperature, and bleeding. RESULTS: There were no statistically significant differences noted in blood loss, surgical time, anesthesia time, pain score, oral intake, vomiting, and postoperative bleeding among the three groups of patients. CONCLUSION: The results showed that a single dose of the intravenous dexamethasone sodium phosphate did not affect the postoperative morbidity in children undergoing sharp dissection tonsillectomy.
