Purpose: The purpose of this study is to demonstrate the usefulness of the high resolutional ultrasonographic features in patients with foreign body. Methods: From September 2007 to August 2009, we retrospectively reviewed high resolutional ultrasonogram using 5~12 MHz linear transducer of 13 patients presenting with inflammation after foreign body injection. They were referred for complications after foreign body injection. Injected foreign bodies were 4 silicone, 4 paraffin, 2 artecoll, and 3 unknown. We treated them with foreign body removal (7), foreign body removal and corrective plastic surgery (4), and conservative treatment with antibiotics and steroid injection (2). Results: High resolutional ultrasonography well demonstrated the existence of foreign body and it's overall size, location within the tissue layer, and vascularity. Comparison between preoperative and postoperative ultrasonographic findings was useful not only to evaluate the prognosis but also to plan the treatment. These ultrasonographic findings aided in precise assessment of the contour and location of the foreign body and led to an accurate surgery. We were able to acquire various information in order to set a detailed plan for the operation which in turn, led to a precise, successful surgery. After the treatment, complication did not occur in 12 patients, except 1 patient. But this patient was also treated after reoperation. Postoperative high resolutional ultrasonography shows almost foreign body removed and inflammation disappeared. Conclusion: Considering the usefulness of highresolution ultrasonography in foreign body injection, highresolution ultrasonography would be necessary for both the patient and the doctor. Preoperative and postoperative high resolutional ultrasonography is highly accurate, safe, inexpensive and easy. It can be a useful modality in foreign body after plastic surgery.

In this study, the rate of bone formation and the pattern of bone to implant contact surface around HA coated implant and pure Ti implant inserted into the irradiated tibia of rabbit were compared. Sixteen mongrel mature male rabbits were used as experimental animal. Each rabbit received 15 Gy of irradiation. Four weeks after irradiation, two holes were prepared on the tibia of each rabbit for placement of HA coated type and pure Ti type implants. Prior to implant placement, one group received steroid irrigation and the control group was similarly irrigated with normal saline. This was immediately followed by placement of the two different types of implants. Postoperatively, tetracycline was injected intramuscularly for 3 days. For fluorescent labelling, 3 days of intramuscular alizarine red injection was given. 2 weeks before sacrifice, followed by intramuscular calcein green on the last 3 days before specimen collection. Each rabbit was sacrificed on the second, fourth, sixth and eighth week after the implantation. The specimens were observed by the light microscope and the fluorescent microscope. The results were as follows; 1. All implants inserted into the irradiated tibia of rabbit were free from clinical mobility and no signs of bony resorption were noted around the site of implant placement. 2. Under the light microscope, new bone formation proceeded faster around implants that received steroid irrigation compared to the control group irrigated with saline. Bone to implant contact surface was greater in the steroid irrigated group than the saline irrigated group. Therefore, better initial stabilization was observed in the group pretreated with steroid irrigation. 3. Under the light microscope. HA coated implants showed broader bone to implant contact surface than pure Ti implants, and HA coated implants had better bone healing pattern than pure Ti implants. 4. In the steroid pretreated group, acceleration of bone formation was demonstrated by fluorescent microscopy around the 2, 4 weeks group and the 6 weeks HA coated implant group. The difference in the rate of bone formation proved to be statistically significant(P<0.05). Faster bone formation was noted in the saline irrigated group in the 6 weeks pure Ti implants and 8 weeks group. The difference was not statistically significant(P<0.05). 5. For the rabbits that were sacrificed on the second and fourth week after the implant placements, the rates of bone formation around HA coated implants proceeded faster than those around pure Ti implants under the fluorescent microscopy. For the rabbits that were sacrificed on the sixth week after the implant placements, the rates of bone formation around pure Ti implants proceeded faster than those around HA coated implants under the fluorescent microscopy. But this result did not show statistical significance (P<0.05) For the rabbits that were sacrificed on the eighth week after the implant placements, the rates of bone formation around HA coated implants proceeded faster than those around pure Ti implants under the fluorescent microscopy. This result was statistically significant (P<0.05).

Purpose: Intramuscular stimulation (IMS) shows good results in the treatment of chronic pain patients who did not respond to other treatments such as oral analgesics, trigger point injection, nerve block and epidural steroid injection. But, IMS procedure especially, patients with diabetes mellitus (DM) has sometimes serious problem. So, we present a very rare case of intramuscular abscess in the sternocleiomastoid muscle after IMS with literature review. Methods: A 66 year old male visited our department 7 days after IMS in the neck. His premorbid conditions and risk factors of deep neck infection was DM and old age. Computed tomographic scans of the head and neck region were performed in this patient: signs of deep neck infection, were seen enhanced abscess in the sternocleidomastoid muscle, cellulitis overlying tissue of the neck, and air bubbles involved muscle. Necrotic wound was excised serially and we treated this with the Vacuum-assisted closure (VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, drainage of the abscess with the VAC system, and then primary closure. The postoperative course was uneventful. Results: We suggest that many of the infectious complications may be preventable by strict adherence to aseptic techniques and that some of the other complications may be minimized by refining the techniques with a clear understanding of the medical disorders of patients. And, the refined technique using the VAC system can provide a means of simple and effective management for the cervical intramuscular abscess, with better cosmetic and functional results.
Nonyphenol (NP) used actively as non-ionic surfactant is classified as one of most potent endocrine disrupting chemicals. Effects of NP on mixed function oxygenase (MFO) system in rockfish (Sebastes schlegeli) were investigated for seven days after intraperitoneal injection (10 and 25 mg $kg^{-1}$). Hepatosomatic index (BSI) of fishes exposed to NP of 25 mg $kg^{-1}$ was significantly reduced compared to those in control group. NP exposure enhanced cytochrome P450 levels in the fish liver, while 7 ethoxyresorufin-O-deethylase (EROD) activity was inhibited. NP exposure levels in this study were much higher than those found in the coastal environment of Korea. Effects on HSI and liver MFO system, which is involved in steroid hormone metabolism, imply that W may influence on reproduction of fish by not only hormone receptor mediated response but also through effects on the MFO system.

Background: Interventional pain management (IPM) is a branch of medical science that deals with management of painful medical conditions using specially equipped X-ray machines and anatomical landmarks. Interventional physiatry is a branch of physical medicine and rehabilitation that treats painful conditions through intervention in peripheral joints, the spine, and soft tissues. Methods: A cross-sectional study was conducted using three years of hospital records (2006 to 2008) from the Physical Medicine and Rehabilitation Department at Chittagong Medical College Hospital in Bangladesh, with a view toward highlighting current interventional pain practice in a tertiary medical college hospital. Result: The maximum amount of intervention was done in degenerative peripheral joint disorders (600, 46.0%), followed by inflammatory joint diseases (300, 23.0%), soft tissue rheumatism (300, 23.0%), and radicular or referred lower back conditions (100, 8.0%). Of the peripheral joints, the knee was the most common site of intervention. Motor stimulation-guided intralesional injection of methylprednisolone into the piriformis muscle was given in 10 cases of piriformis syndrome refractory to both oral medications and therapeutic exercises. Soft tissue rheumatism of unknown etiology was most common in the form of adhesive capsulitis (90, 64.3%), and is discussed separately. Epidural steroid injection was practiced for various causes of lumbar radiculopathy, with the exception of infective discitis. Conclusion: All procedures were performed using anatomical landmarks, as there were no facilities for the C-arm/diagnostic ultrasound required for accurate and safe intervention. A dedicated IPM setup should be a requirement in all PMR departments, to provide better pain management and to reduce the burden on other specialties.

Anatomy: Facet joint syndrome most often affects the lower back and neck and refers to pain that occurs in the facet joints, which are the connections between the vertebrae in the spine that enable the spine to bend and twist. Many physicians have believed that the usual lesion of facet syndrome was an anatomical impairments of facet joint itself.. Facet joint injection using local anesthetics is a reliable method for the diagnosis and treatment for facet syndrome. Etiology: One of many possible causes is imbalances that can occur in stress levels, hormone levels, and nutritional levels. These imbalances can adversely affect posture, which can lead to neck and back pain. The common disorder called facet syndrome exhibits lower back pain, with or without, radiating pain to buttock and thigh due to facet joint arthropathy. Pain in the facet joint is supposedly the secondary effect of narrowing of joint space by sustained muscle contracture around joints. Syndrome: Facet joint syndrome tends to produce pain or tenderness in the lower back that increases with twisting or arching the body, as well as pain that moves to the buttocks or the back of the thighs. Other symptoms include stiffness or difficulty standing up straight or getting out of a chair. Pain can be felt in other areas such as the shoulders or mid-back area. Treatment: Non-drug treatments include hot packs, ultrasound, electrical stimulation, and therapeutic exercises. Stimulating blood flow using massage or a hot tub may also help. Alternative treatments include yoga and relaxation therapy. If your pain persists after trying these treatments, a surgical procedure called radiofrequency rhizotomy, which destroys the sensory nerves of the joint, may bring relief. Facet joint injection has been helpful in diagnosis and therapy for this facet syndrome. Radiofrequency thermocoagulation of medial branches is known to be an effective method of relieving pain caused by facet joint problems. We conclude that spasmolytic treatment of muscles connecting the two vertebral articular space would be better for treatment and diagnosis of facet syndrome rather than facet block with local anesthetic and steroid only.

Background: Ultrasound-guided first sacral transforaminal epidural steroid injection (S1 TFESI) is a useful and easily applicable alternative to fluoroscopy or computed tomography (CT) in lumbosacral radiculopathy. When a needle approach is used, poor visualization of the needle tip reduces the accuracy of the procedure, increasing its difficulty. This study aimed to improve ultrasound-guided S1 TFESI by evaluating radiological S1 posterior foramen data obtained using three-dimensional CT (3D-CT). Methods: Axial 3D-CT images of the pelvis were retrospectively analyzed. The radiological measurements obtained from the images included 1st posterior sacral foramen depth (S1D, mm), 1st posterior sacral foramen width (S1W, mm), the angle of the 1st posterior sacral foramen (S1A, °), and 1st posterior sacral foramen distance (S1ds, mm). The relationship between the demographic factors and measured values were then analyzed. Results: A total of 632 patients (287 male and 345 female) were examined. The mean S1D values for males and females were 11.9 ± 1.9 mm and 10.6 ± 1.8 mm, respectively (P < 0.001); the mean S1A 28.2 ± 4.8° and 30.1 ± 4.9°, respectively (P < 0.001); and the mean S1ds, 24.1 ± 2.9 mm and 22.9 ± 2.6 mm, respectively (P < 0.001); however, the mean S1W values were not significantly different. Height was the only significant predictor of S1D (β = 0.318, P = 0.004). Conclusions: Ultrasound-guided S1 TFESI performance and safety may be improved with adjustment of needle insertion depth congruent with the patient's height.
Background: This study aimed to compare the effectiveness of the pericapsular nerve group (PENG) block and intra-articular injection (IAI) of steroid-bupivacaine in the treatment of hip osteoarthritis (OA). Methods: After randomization, patients received either a PENG block or IAI under ultrasound-guidance. Clinical evaluations were recorded at baseline, day 1, and weeks 1, 4, and 8 post-intervention. The numerical rating scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Harris Hip Scale (HHS) scores, pain medication use determined by a quantitative analgesic questionnaire, and patient satisfaction were evaluated. Results: Sixty patients were included in this study. NRS scores improved significantly for both groups during the follow-up compared to pretreatment (P < 0.001), with better pain scores for the PENG group (P < 0.001) at day 1 with larger effect size (Cohen's d = 4.62), and IAI group at 4 (Cohen's d = 5.15) and 8 (Cohen's d = 4.33) weeks (P < 0.001). There was no significant difference in pain medication consumption (P = 0.499) and patient satisfaction (P = 0.138) between groups. Patients in the IAI group experienced significant improvement in HHS (Cohen's d = 2.16, P = 0.007) and WOMAC (Cohen's d = 1.02, P = 0.036) scores at 8 weeks compared to the PENG group. Conclusions: The ultrasound-guided PENG block provides effective pain relief which improves functionality and quality of life in hip OA patients up to 2 months. The PENG block can be considered an easy, safe, and useful alternative treatment modality for hip OA.

Background and Objective : Laryngeal microscopic surgery (LMS) is popular method to treat for vocal polyp. There is not always the improvement of the voice after operation. Many methods have been developed for better outcome of the surgery. The purpose of this study is to investigate the effect of the triamcinolone injection at vocal cord during LMS. Materials and Methods : The medical records of 28 patients, received LMS under diagnosis of vocal polyp, were retrospectively reviewed. The patients were divided into two groups depending on whether triamcinolone injected or not (case group : Triamcinolone-injected group, control group : Triamcinolone-not injected group). The quality of voice was evaluated by GRBAS scale, fundamental frequency (Fo), jitter, shimmer and NHR (Noise to harmonic ratio) at previous operation, 4 weeks after operation, 8 weeks after operation. Each voice analysis factor was compared between case group and control group by Independent t-test. Results : The mean differences of each voice analysis factor. The mean difference of Jitter, Shimmer, NHR in case group were lower than in control group, and mean difference of GRBAS scale in case group were higher than in control group. These differences were not significant (p>0.05). Conclusion : Though there was a tendency of better voice outcome in patients of triamcinolone-injection, it may not be concluded that the triamcinolone injection is helpful for better voice outcome in surgery of vocal polyp due to statistical insignificance.
A trigger point injection (TPI) has been reported to have an immediate analgesic effect, and to be one of the most widely employed treatment methods of myofascial pain. There are normal saline, local anesthetics, and steroids as the solutions frequently used in TPI. They can be used separately or in combination. Local anaesthetics have myotoxicity in proportion to its concentration. The purpose of this study was to evaluate microstructural changes in point of the myotoxic effects of the combined solution of lidocaine and dexamethasone (a local anesthetic and a steroid) after being injected into the muscle of BALB/c mice. And this study tested solutions with various concentration separately and in combination, to find out proper concentration of solution without muscular tissue damage. This study shows that lidocaine and dexamethasone combination is not histologically myotoxic in case of the concentration of lidocaine less than 1.5%. Also it is suggested from this study that this combined solution will have an analgesic and anti-inflammatory effect. Hereafter continuous study should be performed to reveal that these results can be applied to human when lidocaine and dexamethasone combination is used as an injection modality of TrP treatment.
