RESUMO

RATIONALE: Fibromyalgia (FM) is characterized by idiopathic persistent chronic pain in the ligaments or musculoskeletal system, and more than half of the patients with FM might have migraine headaches. Direct musculoskeletal intervention could be a non-pharmacological management to relieve symptoms. However, patients with severe FM often have intense pain from only a soft touch, thereby rendering musculoskeletal intervention challenging. PATIENT CONCERNS: A 47-year-old man had progressing intense pain, and this affected his everyday life. There were no abnormal physical findings on laboratory examination such as levels of complement, antinuclear antibodies, and C-reactive protein, which were within normal limits. Magnetic resonance imaging did not indicate abnormalities. DIAGNOSES, INTERVENTIONS, AND OUTCOMES: The patient satisfied the American College of Rheumatology criteria. Finally, we made a final diagnosis of fibromyalgia. The therapeutic intervention of Kanshoho, the unique muscle relaxation technique with low force, relieved his pain. LESSONS: If Kanshoho is carefully applied in a state of hospitalization under surveillance by an experienced physician, it could be a promising muscle relaxation method. Relaxing the trapezius muscle and reducing its intramuscular pressure might be key in treating patients with severe FM. However, it needs elucidation of its mechanism.

RESUMO

The knee is a joint that is often injured in sport, with a large and increasing number of ligament tears and repairs; postoperative complications can lead to poor outcome, such as stiffness. Beyond the well-known and well-described intra- and extra-articular causes of postoperative stiffness, the present study introduces the concept of a central reflex motor inhibition mechanism called arthrogenic muscle inhibition (AMI). AMI occurs after trauma and can be defined as active knee extension deficit due to central impairment of Vastus Medialis Obliquus (VMO) contraction, often associated with spinal reflex hamstring contracture. This explains the post-traumatic flexion contracture that is so common after knee sprain. The clinical presentation of AMI is easy to detect in consultation, in 4 grades from simple VMO inhibition to fixed flexion contracture by posterior capsule retraction in chronic cases. After recent anterior cruciate ligament (ACL) tear, more than 55% of patients show AMI, reducible in 80% of cases by simple targeted exercises initiated in consultation. Practically, in patients who have sustained knee sprain, it is essential to screen for this reflex mechanism and assess reducibility, as AMI greatly aggravates the risk of postoperative stiffness. In case of hemarthrosis, we recommend joint aspiration, which provides immediate benefit in terms of pain and motor inhibition. In case of persistent AMI, classical electrostimulation and "cushion crush", as used by all physiotherapists, are ineffective. To reduce the risk of postoperative stiffness, no surgery should be considered until AMI has resolved. LEVEL OF EVIDENCE: expert opinion.

RESUMO

Medical imaging can be used as a medical aid for diagnosis and treatment, and color Doppler ultrasound can also be used in life science research as a scientific research method. Wushu is a traditional sport in China, which has a long history of development. Martial arts are a very good fitness project, but different from ordinary people, professional martial arts athletes are often accompanied by a variety of sports injuries, and tendon ligament injury is one of the most common injuries. At present, there are many treatment plans for tendon and ligament injury, but there are few researches on the repair effect of tendon and ligament injury. This paper will take this as the main research purpose for in-depth study. In view of the problem that ligament injury is not easy to observe, this paper will use GE Lightspeed 64 row spiral CT as the main observation tool and use the method of hospital image observation to compare and analyze the repair effect of tendon and ligament injury of Wushu athletes. In this experiment, 88 professional Wushu athletes were gathered as experimental samples. After preliminary screening, 110 cases of ligament injury were counted. After analyzing the abnormal changes of tissue or structure, Lysholm, and IKDC treatment effect score data, this paper believes that, for type I patients, only conservative treatment can achieve good results. However, in the more serious and complex type II patients, local fixation is used after the onset of the disease, and very serious patients can achieve good results through surgical treatment. Postoperative care is also important, which helps reduce complications. This experiment has achieved ideal results and has played a blank role in the research of the repair effect of tendon and ligament injury of Wushu athletes at home and abroad.

RESUMO

OBJECTIVES: To compare postoperative pain between patients undergoing sacrospinous ligament colpopexy (SSLF) and hysteropexy (SSLH). METHODS: This was a retrospective cohort study of all patients undergoing native tissue SSLF and SSLH between January 2013 and March 2020. The electronic medical record was queried for demographic and perioperative data until the postoperative visit. The primary outcome was a composite incidence of any of the following: telephone calls, urgent office visits, additional analgesic prescriptions and need for intervention for pain in the buttocks, posterior thigh or perirectal area. Secondary outcomes were the incidence of persistent pain at the postoperative visit and perioperative risk factors associated with reported pain. RESULTS: A total of 406 patients met inclusion criteria (308 SSLF, 98 SSLH). The composite pain outcome was seen in 99 patients (24.4%; 95% CI 20.5%-28.8%), and there was no statistical difference between cohorts. Persistent pain was seen in 15.6% and 13.3% of SSLF and SSLH patients at 6 weeks (p = 0.58). Twelve patients (3.0%) underwent interventions for pain, including physical therapy (2), trigger point injections (5) and suture release (5). Compared to SSLF patients, SSLH patients were more likely to need interventions (7 [7.1%] vs. 5 [1.6%], p = 0.005) and office visits (14 [14.3%] vs. 13 [4.2%], p = 0.0005) for pain. CONCLUSIONS: There was no difference in the overall incidence of postoperative pain between patients who underwent SSLF or SSLH. However, patients who underwent hysteropexy were more likely to need intervention and office evaluation for postoperative pain.

RESUMO

OBJECTIVE: To observe the effects of matrix acupuncture on the neck disability index (NDI) score, clinical efficacy, and the calcification size of the nuchal ligament in patients of cervical spondylotic radiculopathy with nuchal ligament calcification. METHODS: A total of 120 cases were randomly divided into a matrix acupuncture group and a routine acupuncture group, with 60 cases in each group. In the matrix acupuncture group, Ashi-point, bilateral Tianzhu (BL10), bilateral Fengchi (GB20), bilateral Dazhu (BL11), bilateral Jianzhongshu (SI15), and Jianjing (GB21), Tianzong (SI11), Quchi (LI11), Shousanli (LI10), Waiguan (TE5), and Hegu (LI4) at the affected side were selected. In the routine acupuncture group, C3-C7 Jiaji points at the neck and Jianjing (GB21), Tianzong (SI11), Quchi (LI11), Shousanli (LI10), Waiguan (TE5), Hegu (LI4), and Ashi-point at the affected side were selected. The patients in the two groups were treated 30 min once, six days a week, for a total of four weeks. The NDI scores, clinical efficacies, and calcification sizes of nuchal ligament were compared between the two groups every wee-kend. RESULTS: After four weeks of treatment, the NDI scores and calcification volumes of nuchal ligament decreased in both groups (P<0.05). Compared with the routine acupuncture group, the matrix acupuncture group showed decreased NDI scores and reduced calcification volumes of nuchal ligament at the 1st, 2nd, 3rd, and 4th weeks of treatment (P<0.05). The cure and marked effective rate in the matrix acupuncture group at the 2nd, 3rd, and 4th weeks of treatment were superior to those of the routine acupuncture group (P<0.05). CONCLUSION: The matrix acupuncture group and the routine acupuncture group are effective in reducing the NDI score and calcification size of nuchal ligament in patients of cervical spondylotic radiculopathy with nuchal ligament calcification. However, matrix acupuncture has obvious advantages over routine acupuncture.

RESUMO

As the resolution of 3D printing techniques improves, the possibility of individualized, 3-ossicle constructions adds a new dimension to middle ear prostheses. In order to optimize these designs, it is essential to understand how the ossicles and ligaments work together to transmit sound, and thus how ligaments should be replicated in a middle ear reconstruction. The middle ear ligaments are thought to play a significant role in maintaining the position of the ossicles and constraining axis of rotation. Paradoxically, investigations of the role of ligaments to date have shown very little impact on middle ear sound transmission. We explored the role of the two attachments in the gerbil middle ear analogous to human ligaments, the posterior incudal ligament and the anterior mallear process, severing both attachments and measuring change in hearing sensitivity. The impact of severing the attachments on the position of the ossicular chain was visualized using synchrotron microtomography imaging of the middle ear. In contrast to previous studies, a threshold change on the order of 20 dB across a wide range of frequencies was found when both ligaments were severed. Concomitantly, a shift in position of the ossicles was observed from the x-ray imaging and 3D renderings of the ossicular chain. These findings contrast with previous studies, demonstrating that these ligaments play a significant role in the transmission of sound through the middle ear. It appears that both mallear and incudal ligaments must be severed in order to impair sound transmission. The results of this study have significance for middle ear reconstructive surgery and the design of 3D-printed three-ossicle biocompatible prostheses.

RESUMO

BACKGROUND: Low levels of vitamin D have well-known impacts on bone health, but vitamin D also has a more global role throughout many tissues, including skeletal muscle. The high prevalence of hypovitaminosis D and the vast physiological features of vitamin D have led researchers to examine the influence of vitamin D on physical performance and injury. Because of the critical role of vitamin D in maintaining musculoskeletal health and function, a high rate of hypovitaminosis D among female patients with a variety of musculoskeletal issues could be of high clinical relevance. HYPOTHESIS: There is a high prevalence of low vitamin D in female patients with both acute and overuse sports-related issues of both soft tissue and bone. STUDY DESIGN: Prospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: Female patients, aged 16 to 40 years, presenting with lower extremity injury diagnosed within the past 4 weeks, no use of multivitamin or vitamin D supplement, and no history of malabsorption syndrome met the inclusion criteria. Vitamin D levels were assessed and categorized as normal (≥32 ng/mL) and low, which includes insufficient (20.01-31.9 ng/mL) and deficient (≤20 ng/mL). RESULTS: Of the 105 patients enrolled, 65.7% had low vitamin D. Within the low vitamin D cohort, 40.6% were deficient and 59.4% were insufficient. Injuries were grouped into overuse or acute with 74 overuse injuries and 31 acute injuries, exhibiting low vitamin D prevalence of 60.8% and 77.4%, respectively. Patients with ligamentous/cartilaginous injuries exhibited the highest percentage of low vitamin D (76.5%), followed by those with patellofemoral-related complaints (71.0%), muscle/tendon injuries (54.6%), and bone stress injuries (45.5%). In univariable analysis, older age, non-White race, less physical activity, less high-intensity interval training days, less endurance training days, and more rest days showed an association with low vitamin D, but none showed an independent association in multivariable analysis. CONCLUSION: The prevalence of low vitamin D in female patients with various musculoskeletal complaints was high. Clinicians should evaluate for low vitamin D in both acute and overuse injuries. CLINICAL RELEVANCE: In addition to screening, this study suggests that clinicians should evaluate for low vitamin D levels beyond bone stress injuries in the setting of acute and overuse injuries.

RESUMO

OBJECTIVES: Prolotherapy or proliferative therapy is a treatment option for damaged connective tissues involving the injection of a solution (proliferant) which theoretically causes an initial cell injury and a subsequent "proliferant" process of wound healing via modulation of the inflammatory process. Nonetheless, the benefits of dextrose prolotherapy have not been adequately evaluated. Therefore, the present study assesses the effectiveness and superiority of prolotherapy separately in treating dense fibrous connective tissue injuries. METHODS: PubMed, Scopus, and Embase were searched from the earliest record to February 18, 2019. This study included randomized controlled trials whichBoth analysis at individual studies level and pooled meta-analysis were performed. RESULTS: Ten trials involving 358 participants were included for review. At study level, the majority of comparisons did not reveal significant differences between dextrose prolotherapy and no treatment (or placebo) regarding pain control. The meta-analysis showed dextrose prolotherapy was effective in improving activity only at immediate follow-up (i.e., 0-1 month) (standardized mean difference [SMD]: 0.98; 95% confidence interval [CI]: 0.40-1.50; I = 0%); and superior to corticosteroid injections only in pain reduction at short-term follow-up (i.e., 1-3 month) (SMD: 0.70; 95% CI: 0.14-1.27; I = 51%). No other significant SMDs were found in this analysis. CONCLUSIONS: There is insufficient evidence to support the clinical benefits of dextrose prolotherapy in managing dense fibrous tissue injuries. More high-quality randomized controlled trials are warranted to establish the benefits of dextrose prolotherapy. REVIEW REGISTRATION: PROSPERO (CRD42019129044).

RESUMO

INTRODUCTION AND HYPOTHESIS: This study compared anatomical and clinical outcomes of traditional McCall culdoplasty versus a modified McCall technique with double ligament suspension (DLS). METHODS: This retrospective study presents outcomes of 68 patients who underwent vaginal hysterectomy and vaginal suspension for apical prolapse ≥ stage II according to the POP-Q score system, at, between January 2016 and February 2018. In 34 women vaginal cuff suspension was obtained with traditional McCall culdoplasty (McCall group), while in 34 women we performed a modified McCall, which consists of a double ligament suspension (DLS group), suspending the vaginal cuff to uterosacral ligaments and also to adnexal peduncles. Primary outcome was prolapse recurrence ≥ stage II according to the POP-Q system. Fisher's, Mann-Whitney U and Student's t tests were used for statistical analysis. RESULTS: There were no statistical differences among patients' preoperative characteristics, operative time, blood loss or postoperative complications. Follow-up mean duration was 23.2 ± 6.7 and 22.4 ± 8.7 months in the McCall and DLS group, respectively. Prolapse recurrence occurred in 11 (32.3%) women in the McCall group versus 2 (5.9%) women in the DLS group (p < 0.05): among them, 2 patients (5.9%) in the McCall group and 1 (2.9%) in the DLS group required further treatment. Total vaginal length was 6.1 ± 0.9 cm in the McCall group versus 6.9 ± 0.7 cm in the DLS group (p < 0.001). No statistical difference in quality of life assessment was observed. CONCLUSIONS: DLS group patients had better anatomical outcomes and lower recurrence rates than McCall group patients, without increasing operative time or complications. A prospective study with more cases is needed to confirm our data.

RESUMO

BACKGROUND: The Pringle maneuver is often used in liver surgery to minimize bleeding during liver transection. Many authors have demonstrated that intermittent use of the Pringle maneuver is safe and effective when performed appropriately. However, some studies have reported that the Pringle maneuver is a significant risk factor for portal vein thrombosis. In this study, we evaluated the effectiveness of portal vein flow after the Pringle maneuver and the impact that massaging the hepatoduodenal ligament after the Pringle maneuver has on portal vein flow. MATERIALS AND METHODS: Patients treated with the Pringle maneuver for hepatectomies performed to treat hepatic disease at our hospital between August 2014 and March 2019 were included in the study (N = 101). We divided these patients into two groups, a massage group and nonmassage group. We measured portal vein blood flow with ultrasonography before and after clamping of the hepatoduodenal ligament. We also evaluated laboratory data after the hepatectomy. RESULTS: Portal vein flow was significantly lower after the Pringle maneuver than before clamping of the hepatoduodenal ligament. The portal vein flow after the Pringle maneuver was improved following massage of the hepatoduodenal ligament. After hepatectomy, serum prothrombin time was significantly higher and serum C-reactive protein was significantly lower in the massage group than in the nonmassage group. CONCLUSION: Massaging the hepatoduodenal ligament after the Pringle maneuver is recommended in order to quickly recover portal vein flow during hepatectomy and to improve coagulability.

RESUMO

An 88-year-old woman with a history of recent complicated pacemaker insertion presented with acute-onset malignant glaucoma recalcitrant to conservative medical therapy. Surgical intervention was discussed; however, given her complex cardiac history and recent postoperative state, the risk of anesthesia-related systemic adverse events was deemed unacceptably high. As such, a slit-lamp procedure was recommended to break the attack of malignant glaucoma. Here within, we report a novel technique of breaking an attack of malignant glaucoma by needling the anterior hyaloid face at the slit lamp. With this technique, a 25-G needle was entered through the pars plana and was advanced through the anterior hyaloid face, zonules, and peripheral iridotomy to create a unicameral eye and successfully break the malignant closure attack.

RESUMO

Hyperbaric oxygen therapy (HBOT) is a well-established treatment for a variety of conditions. Hyperbaric oxygen therapy is the administration of 100% oxygen breathing in a pressure vessel at higher than atmospheric pressure (1 atmosphere absolute = 101 kPa). Typically, treatment is given daily for between 1 and 2 h at pressures of 2.0 to 2.8 ATA, depending on the indication. Sporting injuries are often treated over 3 to 10 sessions. Hyperbaric oxygen therapy has been documented to be effective and is approved in 14 medical indications by the Undersea and Hyperbaric Medical Society, including, but not limited to, carbon monoxide poisoning, compromised skin grafts and flaps, crush injuries, necrotizing soft tissue infections, and nonhealing ulcers with arterial insufficiencies. Recently, HBOT for sports musculoskeletal injuries is receiving increased attention. Hyperbaric oxygen therapy may allow injured athletes to recover faster than normal rehabilitation methods. Any reduction in collegiate and professional athletes' rehabilitation period can be financially significant for top-level sports teams; however, further research is required to confirm HBOT's benefits on sports musculoskeletal injuries. The purpose of this review to discuss the current understanding of HBOT as a treatment modality for common musculoskeletal injuries in sport medicine. Moreover, we will highlight the advantages and disadvantages of this modality, as well as relevant clinical and research applications.

RESUMO

Rich in bioactive substances such as amino acids and peptides, Laennec (human placenta hydrolysate) has been widely used to control various types of musculoskeletal pain. However, the effects of Laennec on tendon and ligament injuries are not clearly understood. In the present study, Laennec was tested to identify its in vivo effects on ligament injury in an animal model and its in vitro effects on tendon-derived fibrocytes. A total of 99 Sprague Dawley rats were divided into the negative control (normal) group (n = 11) and the ligament injury group (n = 88). The ligament injury group was subdivided into normal saline-treated group, Laennec-treated group, polydeoxyribonucleotide-treated group, and 20% dextrose-treated group. Ligaments were collected at 1 week and 4 weeks after treatment. Histologic and biomechanical properties were analyzed. In vitro effects of Laennec and polydeoxyribonucleotide on fibrocytes were also analyzed. Although all other treatment groups showed increased inflammatory cells, the Laennec-treated group maintained cell counts and activated macrophage levels that were similar to the normal group. Unlike the saline-treated group and dextrose-treated group, the Laennec-treated group had low levels of degenerative changes at 4 weeks after treatment. Supportively, in vitro results showed that the Laennec-treated group had increased collagen type I, scleraxis (Scx) and tenomodulin (Tnmd) expression (p < 0.05). Our study demonstrates that Laennec treatment enhances wound healing of damaged ligament by suppressing immune responses and reducing degenerative changes of damaged ligament. In addition, we found that Laennec induces the gene expression of type I collagen, Scx and Tnmd in fibrocytes, suggesting that Laennec may facilitate regeneration of damaged ligaments. Therefore, we expect that Laennec can be a useful drug to treat injured ligament.

RESUMO

BACKGROUND Periodontitis is a chronic inflammatory disease that causes gingival detachment and disintegration of alveolar bone. Salvianolic acid C (SAC) is a polyphenol compound with anti-inflammatory and antioxidant activities that is isolated from Danshen, a traditional Chinese medicine made from the roots of Salvia miltiorrhiza Bunge. The aim of this study was to investigate the mechanisms of underlying its protective effects and its inhibition effect on inflammation and apoptosis in human periodontal ligament stem cells (hPDLSCs). MATERIAL AND METHODS LPS-induced hPDLSCs, as a model mimicking an inflammatory process of periodontitis in vivo, were established to investigate the therapeutic effect of SAC in periodontitis. The inflammatory cytokines secretion and oxidative stress status were measured by use of specific commercial test kits. The hPDLSCs viability was analyzed by Cell Counting Kit-8 assay. The cell apoptosis and cell cycle were assayed with flow cytometry. Expressions levels of proteins involved in apoptosis, osteogenic differentiation, and TLR4/NF-kappaB pathway were evaluated by Western blotting. Alkaline phosphatase (ALP) activity was detected by ALP assay kit and ALP staining. The mineralized nodules formation of hPDLSCs was checked by Alizarin Red S staining. RESULTS Our results showed that LPS induced increased levels of inflammatory cytokines and oxidative stress and mediated the phosphorylation and nuclear translocation of NF­kappaB p65 in hPDLSCs. SAC reversed the abnormal secretion of inflammatory cytokines and inhibited the TLR4/NF­kappaB activation induced by LPS. SAC also upregulated cell viability, ALP activity, and the ability of osteogenic differentiation. The anti-inflammation and TLR4/NF­kappaB inhibition effects of SAC were reversed by TLR4 overexpression. CONCLUSIONS Taken together, our results revealed that SAC effectively attenuates LPS-induced inflammation and apoptosis via the TLR4/NF-kappaB pathway and that SAC is effective in treating periodontitis.

RESUMO

OBJECTIVE: To evaluate the effectiveness and success of uterus preserving sacrospinous hysteropexy as an alternative to vaginal hysterectomy with uterosacral ligament suspension in the surgical treatment of uterine prolapse five years after surgery. DESIGN: Observational follow-up of SAVE U (sacrospinous fixation versus vaginal hysterectomy in treatment of uterine prolapse ≥2) randomised controlled trial. SETTING: Four non-university teaching hospitals, the Netherlands. PARTICIPANTS: 204 of 208 healthy women in the initial trial (2009-12) with uterine prolapse stage 2 or higher requiring surgery and no history of pelvic floor surgery who had been randomised to sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension. The women were followed annually for five years after surgery. This extended trial reports the results at five years. MAIN OUTCOME MEASURES: Prespecified primary outcome evaluated at five year follow-up was recurrent prolapse of the uterus or vaginal vault (apical compartment) stage 2 or higher evaluated by pelvic organ prolapse quantification system in combination with bothersome bulge symptoms or repeat surgery for recurrent apical prolapse. Secondary outcomes were overall anatomical failure (recurrent prolapse stage 2 or higher in apical, anterior, or posterior compartment), composite outcome of success (defined as no prolapse beyond the hymen, no bothersome bulge symptoms, and no repeat surgery or pessary use for recurrent prolapse), functional outcome, quality of life, repeat surgery, and sexual functioning. RESULTS: At five years, surgical failure of the apical compartment with bothersome bulge symptoms or repeat surgery occurred in one woman (1%) after sacrospinous hysteropexy compared with eight women (7.8%) after vaginal hysterectomy with uterosacral ligament suspension (difference-6.7%, 95% confidence interval -12.8% to-0.7%). A statistically significant difference was found in composite outcome of success between sacrospinous hysteropexy and vaginal hysterectomy (89/102 (87%) v 77/102 (76%). The other secondary outcomes did not differ. Time-to-event analysis at five years showed no differences between the interventions. CONCLUSIONS: At five year follow-up significantly less anatomical recurrences of the apical compartment with bothersome bulge symptoms or repeat surgery were found after sacrospinous hysteropexy compared with vaginal hysterectomy with uterosacral ligament suspension. After hysteropexy a higher proportion of women had a composite outcome of success. Time-to-event analysis showed no differences in outcomes between the procedures.

RESUMO

OBJECTIVES: Defects in female pelvic organ support are highly prevalent. Uterosacral ligament suspension at the time of primary prolapse repair (McCall culdoplasty) is a well-established surgical option to prevent prolapse recurrences. Recently Shull's high uterosacral ligament suspension technique has gained increasing popularity among Uro-Gynaecologists. A study carried out in 2017 by Spelzini et al. compared these two techniques, showing proper safety and efficacy in the treatment of prolapse, with no statistically significant differences as to operative time, complication rate, anatomical, functional and subjective outcomes [1]. Our study aims at comparing the effectiveness, complication rate, recurrence rate, quality of life and functional result of the two techniques. STUDY DESIGN: This is a retrospective study carried out on 224 patients who underwent vaginal cuff suspension for pelvic organ prolapse. Cases were extracted from hospital medical records of all women managed with surgical prolapse repair at our Gynaecology and Obstetrics department between January 2013 and February 2017. Shull suspension (group A) or McCall culdoplasty (group B) were performed according to surgeon's familiarity with the two suspension techniques. RESULTS: A total of 224 patients (69 in group A and 155 in group B) underwent surgical cuff suspension. Median operating time was 88 min for both techniques and ureteral injuries were very rare in both group A and B (1 and 0 respectively). In the evaluation of postoperative questionnaires, no statistically significant differences were found, except for "Urinary Impact Questionnaire" (UIQ), which showed significantly less urinary subjective symptoms in group A. Median follow up was 13 months in group A and 15 months in group B. Post-operative Pop-Q items analysis revealed only a higher Aa point in group A at 12 months follow up visit. Objective vaginal cuff recurrence was observed in 1 patient (1,4%) in group A and 4 patients in group B (2,6%) with no statistically significant difference between the two groups. CONCLUSIONS: Both uterosacral ligament suspension procedures are safe and highly effective. There were no statistically significant differences concerning surgical data, complication rates, and the majority of anatomical, functional and subjective outcomes between Shull suspension and McCall culdoplasty.

RESUMO

Torticollis is an abnormal, asymmetric head or neck position which usually caused by imbalance of paracervical muscles. The traumatic torticollis can be caused by following events; atlantoaxial rotatory subluxation, atlantoaxial dislocation, cervical vertebral fractures, and injury to the cervical musculature. Especially, acute traumatic atlantoaxial rotatory subluxation usually presents limitation of cervical range of motion without pain or neurologic deficit. We report a case of a 58 year-old man who developed the acute atlantoaxial rotatory subluxation right after the chiropractic therapy, which induced the limitation of cervical range of motion to 52.5% of normal range. The magnetic resonance image revealed the facture of the odontoid process and the partial injury in transverse ligaments of the atlas. He underwent intramuscular botulinum toxin injection and 10 days of continuous cervical traction 15 hours a day using a 5 kg weight. The range of the cervical motion restored up to 90.2% of normal range.

RESUMO

INTRODUCTION: Exogenous Nel-like molecule type 1 (NELL1) represents a potentially attractive clinical treatment option in the orthodontic and other settings because of its osteoinductive and vasculogenic properties. AIMS: To explore effects of NELL1on corticotomy-assisted tooth movement and osteogenesis in a rat model. METHODS: Thirty Sprague-Dawley rats were divided into 6 groups: Control, Sham, Tooth movement only, Vehicle, NELL1-LD (low-dose NELL), NELL1-HD (high-dose NELL). Human recombinant NELL1 protein was applied locally (Groups NELL1-LD and NELL1-HD) into buccal mucosa region of left first upper molar. Then the distance and velocity of tooth movement was measured, animals at 6 weeks after surgery were sacrificed, and was followed by computed tomography and histochemical staining. RESULTS: Both NELL1 groups had higher bone mineral density, greater tooth movement distance and velocity in comparison to the Vehicle group. Proximally and distally, periodontal ligament width was significantly increased in the NELL1-LD and NELL1-HD groups. Decortication enhances remodeling, however, rapid bone formation by high-dose NELL1 may affect bone absorption. CONCLUSION: Appropriate dose of NELL1 can be administrated to reduce the total time for tooth movement, and may shorten the treatment time in select populations.
