Background: The genicular nerve block (GNB) is demonstrated from several reports to alleviate pain and improve knee functionality in patients with chronic knee osteoarthritis (OA). Ultrasound (US)-guided GNB has been the most used imaging method. This study aimed to compare the effectiveness of US-guided versus blind GNB in the treatment of knee OA. Methods: This prospective, randomized clinical trial included patients with knee OA based on American College of Rheumatology diagnostic criteria. The patients were evaluated for clinical and dynamometer parameters at the baseline, 4 weeks after treatment, and 12 weeks after treatment. The patients underwent blind injection or US-guided injection. Results: When compared with the baseline, both groups showed significant improvement in pain, physical function, and quality of life parameters. Significant differences were observed between the groups for clinical parameters (30-second chair stand test, 6-minute walk test) in favor of the US-guided group. On the other hand, blind injection was more significantly effective on some parameters of the Nottingham Health Profile. There wasn't any significant improvement in isokinetic muscle strength for either group. Conclusions: This study demonstrated that both US-guided and blind GNB, in the treatment of knee OA, were effective in reducing symptoms and improving physical function. GNB wasn't an effective treatment for isokinetic muscle function. US-guided injections may yield more effective clinical results than blind injections.

Background: We prospectively compared the response to blind and ultrasound-guided glenohumeral injection of corticosteroids for treatment of shoulder stiffness. Methods: A total of 77 patients with shoulder stiffness between April 2008 and March 2012 were recruited. Patients were randomized to receive either a blind (group 1, n=39) or ultrasound-guided (group 2, n=38) glenohumeral injection of 40 mg triamcinolone. The clinical outcomes and shoulder range of motion (ROM) before injection, at 3, 6, and 12 months after injection and at the last follow-up were assessed. The same rehabilitation program was applied in both groups during the follow-up period. Results: There was no significant difference in demographic data on age, sex, ROM, and symptom duration before injection between groups (p>0.05). There were no significant differences in ROM including forward flexion, external rotation at the side, external rotation at $90^{\circ}$ abduction, and internal rotation, visual analogue scale for pain and functional outcomes including American Shoulder and Elbow Surgeons score, Simple Shoulder test between the two groups at any time point (p>0.05). Conclusions: Based on the current data, the result of ultrasound-guided glenohumeral injection was not superior to that of blind injection in the treatment of shoulder stiffness. We suggest that ultrasound-guided glenohumeral injection could be performed according to the patient's compliance and the surgeon's preference. Once familiar with the non-imaging-guided glenohumeral injection, it is an efficient and reliable method for the experienced surgeon. Ultrasound could be performed according to the surgeon's preference.

Purpose: We wanted to compare the accuracy between the blind anterior approach and ultrasound guided posterior approach, which are preferred in the present clinical practice for the glenohumeral joint injection. Materials and Methods: The consecutive 95 cases were included in that the glenohumeral joint injection was done in the university hospital and the medical record and ultrasonography were available. There were 52 cases which were injected by blind anterior approach (group I) and 43 cases who were injected by ultrasound guided posterior approach (group II). The injection was decided as accurate if the fluid was visualized in the posterior joint under the ultrasound. We evaluated the range of motion before and after 2 weeks of injection. A subjective satisfaction of the patients was interviewed at the 2 weeks after injection. Results: The accuracy of the glenohumeral joint injections of the group I and group II was 80.8% and 90.7%, respectively. The range of motion was improved for the all cases regardless of the approaches. At the 2 weeks after injection, the subjective satisfaction (better than good) was achieved in 73.7%. Conclusion: The accuracy of the blind anterior approach for the glenohumeral joint injection was 80.8%. The accuracy of the ultrasound guided posterior approach was 90.7%. In this comparative study by the one physician, the ultrasound guided posterior approach showed the better accuracy.

Pharmacological ablation of the ciliary body by intravitreal injection of a cytotoxic dose of gentamicin was utilized for the treatment of absolute glaucoma in 13 dogs. Complications of this procedure were hyphema(2), corneal opacity(2), iris bombe(1), cataract(1) and chronic inflammation(1). Injection time was one time in 10 dogs, two times in 2 dogs and 3 times in a dog. Intravitreal injection of gentamicin was thought as a economic salvage procedure and has resulted in successful lowering of intraocular pressure.

This experiment has investigated the influence of Yamen (Du. 15) point injection on learning and memory dysfunction caused by cerebral ischemia and reprofusion in bilateral cervical general artery combined with bleeding on mouse tail to mimic vascular dementia in human beings. By dividing 40 mice into 4 groups (group1false operation group, group2model group, group3point injection with Cerebrolysin group4point injection with saline.) According to random dividing principles, we observed the influence of Yamen(Du. 15) point injection on the time of swimming the whole course used by model mice which had received treatment for different days in different groups, and the influence of those mice on wrong times they entered blind end. The result showed that point injection with Cerebrolysin and saline could improve learning and memory dysfunction of the mice caused by cerebral ischemia.

Purpose: We compared with USG-guided steroid injection group and blind steroid injection group for the treatment of calcific tendinitis to evaluate the effectiveness of the treatment modalities. Materials and Methods: We reviewed two groups of calcific tendinitis treated with steroid injection and follow up upto 6 month after injection. Group I was blind injection for 88 patient with average age of 53years old and female gender in 77%. Group II was USG- guided injection for 102 patients with average age of 54years old and female gender in 85%. We compared follow up results according to age, gender, size of tendon involvement, initial VAS score, and phase of the calcific tendinitis between two groups. Results: At 6 month's follow up period, USG-guided injected group was more prevalent compared to blind injection group with 92%(94/102) and 72%(64/88) (P<0.05). In Group I, 77%(49/64) patients have improved symptom. And in Group II, 92%(86/94) patients have improved symptom in formative or resorptive phase. Despite of symptom improvement, calcium deposit is remained 47%(30/64) in Group I, and 20%(19/94) in Group II. Conclusion: Conservative treatment of Shoulder calcific tendinitis patients through USG-guided injection is more effective than Blind injection in pain relief & calcium decrease. The patients USG-guided injected group was more prevalent in follow up at outpatient clinic, throughout more accurate injection with improved confidence.

Purpose: To evaluate the differences between blindly and ultrasonography (US)-guided during multiple needling and dextrose injection technique for calcific tendinitis of shoulder. Materials and Methods: We chose 36 symptomatic calcific tendinitis patients, whose age ranged from 27 to 69. Our procedures were multiple needling and injection of dextrose over the lesion of calcific deposits. The bind injection group were 19 patients whose age ranged from 27 to 64-year-old (mean 52.2), and the US-guided injection group were 17 patients ranged from 31 to 69-year-old (mean 49.0). We compare these groups by VAS (visual analogue scale) and range of motion before and after procedures. Results: There is no difference between two groups in VAS and ROM before procedure (p>0.05). Two groups revealed significant improvement without limitation of shoulder function, however, the group under US-guided revealed better results than under blind (VAS:p=0.001, Flexion:p=0.000, Abduction:p=0.000, External rotation: p=0.016). Conclusion: Ultrasonography-guided procedure showed better results than blind, so the use of ultrasonography is more promising procedure.

A dual capillary column system is described for the simultaneous analysis of a given sample and measurement of retention index (RI) and area ratio (AR) values of each peak on two capillary columns of different polarity, DB-5 & DB-1701 from a single injection. Both capillary columns were connected to either a splitless injector or an on-column injector via a deactivated fused-silica capillary tubing of 1 m length and a 'Y' splitter. Both injection modes allowed to measure RI and AR values with high reproducibility (<0.01% RSD) and high accuracy (<10% RE), respectively with the exception that the trace and high boiling solutes required the on-column mode for the accurate quantification and AR comparison. When the dual capillary column system in on-column injection mode was applied to the blind samples containing organic acids, each acid was positively indentified by the combined computer RI library search-AR comparison.

Caudal epidural injection is a common intervention in patients with low back pain and sciatica. Even though the complications of fluoroscopically directed epidural injections are less frequent than in blind epidural injections, complications due to contrast media can occur. We report a case of anaphylactic shock immediately after injection of an intravenous nonionic contrast medium (iohexol) during the caudal epidural injection for low back pain and sciatica in a patient without a previous allergic history to ionic contrast media (ioxitalamate). Five minutes after the dye was injected, the patient began to experience dizziness, and the systolic blood pressure dropped to 60 mmHg. Subsequently, the patient exhibited a mild drowsy mental state. About 30 minutes after the subcutaneous injection of 0.2 mg epinephrine, the systolic blood pressure increased to 90 mmHg. The patient recovered without any sequela. Life-threatening complications after injection of intravenous contrast medium require immediate treatment.

Treatment of osteoarthritis of the ankle joint is similar to that of any other large joint and includes conservative and surgical treatments. Surgical option in severe osteoarthritis is joint fusion or joint replacement, whereas conservative treatment is limited and includes mainly ankle supports, physical therapy, and oral medication. Hyaluronic acid was discovered in 1934 and now has been widely used in the knee and shoulder joints. We reviewed the articles about an intra-articular hyaluronic acid injection in the treatment of osteoarthritis of the ankle joint.
