The effect of cervical mobilization on joint position sense, balance and gait in patients with multiple sclerosis: a randomized crossover study

OBJECTIVE

To investigate the effect of cervical mobilization on joint position sense, balance and gait in multiple sclerosis (MS) patients.

METHODS

Sixteen MS patients received traditional rehabilitation and traditional rehabilitation+cervical mobilization treatments in different orders, 2 days a week for 4 weeks. For the cervical mobilization, joint traction and shifts with myofascial release techniques were applied. Joint position sense was evaluated from the bilateral knee and ankle joints with a digital goniometer, balanced with the Berg Balance Test (BBT), the Functional Reach Test, and gait with the Dynamic Gait Index (DGI) and the Timed 25-Foot Walk Test.

RESULTS

Improvements were determined in joint position sense, balance, gait with both treatment methods (p < 0.05). With the addition of cervical mobilization to traditional treatment, there was observed to be an increased effect carried over in knee joint position sense and BBT (p < 0.05). The BBT and DGI scores improved in the group applied with cervical mobilization following the washout period (p < 0.05).

CONCLUSIONS

Cervical mobilization could be effective in improving joint position sense, balance and gait, and accelerated improvements in a short time. The application of cervical mobilization could be a supportive treatment method to improve position sense, balance and gait in patients with MS.

Comparative anatomy and evolution of the atlantoaxial complex in the fossorial lineage Amphisbaenia (Squamata: Lacertoidea)

The atlas and axis are the first two vertebrae from the cervical series; these two vertebrae are responsible for neck flexion, extension, and rotation movements, while providing insertion points for muscles and tendons. Amphisbaenia is a group of fossorial squamates known for having four distinctive head shapes, which are related to different excavation methods. However, little is known about the relationship between these different digging patterns and the anatomy and evolution of the atlantoaxial complex. In this study, we used computed microtomography data to describe in detail of the atlantoaxial complex for 15 species, belonging to all six current families of Amphisbaenia. Furthermore, we evaluate evolutionary scenarios of selected characters related to the atlantoaxial complex in the most recent phylogeny for Amphisbaenia, using the criteria of parsimony and maximum likelihood. Our results indicate that the evolutionary pattern of the atlantoaxial complex presents a diversification in its morphology that is not always correlated with the shape of the head. This analysis reinforces the hypothesis of remarkable morphological convergences in the evolutionary history of Amphisbaenia. Additionally, some of the characters studied may represent independent evolution through convergence in some cases (e.g., horizontal axis of the neural column) and parallelism in others (e.g., present or absent from the transverse process).

Effectiveness of spinal mobilization and postural correction exercises in the management of cervicogenic headache: A randomized controlled trial

OBJECTIVE

The study aims to assess the effect of spinal mobilization and postural correction exercises in patients suffering from cervicogenic headache.

METHODS

A randomized controlled trial was conducted with 72 patients. Patients were randomly allocated into three groups: spinal mobilization (n = 24), postural correction exercises (n = 24), and control group (n = 24). The primary outcome measure was headache impact test-6, and secondary outcomes were headache intensity, neck pain intensity, and neck pain-related disability measured at baseline, postintervention, and follow-up period.

RESULT

Comparison of baseline data (at 0 weeks) among groups showed a statistically nonsignificant difference. There was statistically significant improvement at postintervention (immediately after fourth week) in postural correction exercises group [headache disability: 14.95 ± 7.91 (p < .001); headache intensity: 2.58 ± 1.24 (p < .001); neck disability: 27.66 ± 18.71 (p < .001); neck pain: 1.91 ± 1.44 (p < .001)] and spinal mobilization group [headache disability: 13.83 ± 6.21 (p < .001); headache intensity: 2.29 ± 1.23 (p < .001); neck disability: 23.39 ± 19.51 (p < .001); neck pain: 1.72 ± 0.84 (p < .001)] as compared to the control group. The result of within-group analysis suggests that there was a statistically significant improvement in postintervention (immediately after fourth week) and follow-up (immediately after eighth week) scores as compared to baseline (at 0 weeks) scores for all outcomes in postural correction exercises [headache disability (p < .001), headache intensity (p < .001), neck disability (p < .001), neck pain (p < 0 .001)] as well as in spinal mobilization group [headache disability (p < .001), headache intensity (p < .001), neck disability (p < .001), neck pain (p < .001 for pre versus post; p = .001 for pre versus follow-up)]. There was a statistically nonsignificant difference between postintervention and follow-up scores of all the outcomes in the postural correction exercise and spinal mobilization group, which indicates that improvement in these groups was maintained during the follow-up period.

CONCLUSION

Spinal mobilization and postural correction exercises are effective in the management of cervicogenic headache.

Cervical intranodal schwannoma - a rare diagnosis

Intranodal schwannoma is a rare benign tumor, which originates from the peripheral nerve sheath (Schwann cells), fewer cases being reported with lymphatic involvement. We present the case of a middle-aged female patient, with one-year growing mass in the lateral-cervical area, in intimate relation with the vascular package of the neck. Preoperative cervical computed tomography examination showed the tumor features. There was no intraoperative complication, with the piece being completely removed. The morphological examination revealed the structure of a lymph node, and after Hematoxylin-Eosin staining, there were eosinophilic cytoplasm, euchromatic nuclei, with round, elongated or slightly wavy form and reduced pleomorphism, rare degenerative nuclear atypia, and no mitotic activity nor necrosis. The expression of S100 protein on immunohistochemistry, along with negative results for smooth muscle actin and desmin sustained the diagnosis of intranodal schwannoma of the neck. With a low index of cellular proliferation (Ki67), this case is in line with the reported features of schwannoma having extremely rare malignant transformation.

A Case Report: An Acute Spinal Epidural Hematoma after Acupuncture Mimicking Stroke

BACKGROUND

Spinal epidural hematoma (SEH) after acupuncture is rare and may present with acute or subacute onset and varied symptoms, making it difficult to diagnose. This condition can mimic acute stroke, so it is vital to establish a clear diagnosis before considering thrombolytic therapy, which could be disastrous if applied inappropriately.

CASE REPORT

We describe a 52-year-old man who presented to our emergency department (ED) with acute onset of unilateral weakness of the limbs for 3.5 h immediately after receiving acupuncture at the bilateral neck and back. The acute stroke team was activated. In the ED, computer tomography angiography from the aortic arch to the head revealed spinal epidural hematoma. The patient was admitted to the ward for conservative treatment and was discharged with subtle residual symptoms of arm soreness 5 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute spinal epidural hematoma rarely presents with unilateral weakness of the limbs, mimicking a stroke. Because inappropriate thrombolysis can lead to devastating symptoms, spinal epidural hematoma should be excluded when evaluating an acute stroke patient with a history of acupuncture who is a possible candidate for thrombolytic therapy.

Mixed Thymoma in an American Robin ( Turdus migratorius)

A mixed thymoma was diagnosed in a 15-year-old female American robin ( Turdus migratorius) that exhibited poor body condition, dysphagia, hyporexia, and depression. A 1.5-cm subcutaneous nodule was present in the cranio-ventral cervical region, which had been noticed by the owner 15 days before presentation. On cytologic evaluation of a fine-needle aspirate, well-differentiated lymphocytes were observed. Surgical excision was elected; however, the mass was firmly attached to the esophagus and the jugular vein, and the attempt at excision resulted in fatal hemorrhage. On histologic examination of the mass, small, well-differentiated lymphocytes were observed mixed with neoplastic reticular cells and Hassall's corpuscles. On immunohistochemical analysis, the cytoplasm of 80% of the reticular cells showed abundant detectable brown antigen binding with pancytokeratin staining, and most lymphoid cells showed detectable antigen in the cytoplasm by using CD3 antibodies. The cytologic, histopathologic, and immunohistochemical features of the neoplasm in this robin were consistent with a mixed thymoma.

CERVICAL LIPOSARCOMA IN A 22 YEAR OLD MAN- AN UNCOMMON PRESENTATION

Liposarcomas are uncommon malignant growths, most of which occur in the retroperitoneum and lower extremities. Liposarcoma arising in the head and neck is an uncommon and a potentially life threatening malignancy. We present a 22 year-old male with a dedifferentiated cervical liposarcoma, who had local excision, with no recurrence at twenty months of follow-up. This patient has drawn our attention to the fact that although liposarcomas are rare in the neck and commonly occur in patients between 40 and 60 years, any neck swelling in the young with atypical features should raise suspicion as to the possibility of malignancy.

Metastatic Thymoma in a Scarlet Macaw ( Ara macao )

A 49-year-old female scarlet macaw ( Ara macao ) was presented with a mass in the cervical region. The bird showed no evidence of pain or discomfort, it swallowed food normally, and its breathing pattern was unremarkable. Results of contrast radiographic imaging revealed a well-demarcated mass in the right cervical region not related to the crop. After surgical resection and histopathologic evaluation, a malignant nodular stage of an epithelioid cortical-type thymoma was diagnosed. One year later, metastasis of the thymoma to the lung was diagnosed and confirmed at postmortem examination. The final diagnosis was corrected to malignant nodular stage of an epithelioid cortical-type thymoma with metastasis to the lung. This is the first report in an avian species of a malignant thymoma with metastasis to the lung after complete resection of the initial cervical thymoma and a survival time of 1 year.

[Plunging goitre in Tlemcen in western Algeria: clinical and therapeutic aspects of 1996-2014]

La définition du goitre plongeant, la plus couramment employée, est tout goitre ne siégeant pas dans la région cervicale en position opératoire. Le but d’évaluer sa prise en charge, en insistant plus particulièrement sur les examens préopératoires, les difficultés chirurgicales et les complications postopératoire. Etude rétrospective étalée sur 16 ans; portant sur 50 cas colligés au service de chirurgie viscérale du CHU Tlemcen. L'intervention a consisté en une thyroïdectomie totale par voie cervicale dans 94% des cas. Ont été notées essentiellement, les hématomes, des paralysies récurentiels et les hypoparathyroïdie. L’âge moyen est de 54,76 ±11,992 ans Le caractère plongeant du goitre à été retrouvé chez 52% (n = 26) par une échographie thyroïdienne. Le scanner cervico-thoracique était pratiqué chez 25 patients 50%. Il a permis de confirmer le caractère plongeant du goitre. Tous nos patients ont bénéficié eu un geste radicale (thyroïdectomie totale n = 45, 90%), alors que 5 patients (10%) ayant déjà ont eu un geste sur la thyroïde, ont subi une totalisation. L'examen histologique à confirmé la bénignité dans 48 cas 96%. Trois patients (6%) avaient une paralysie récurentielle transitoire et un cas (2%) de paralysie récurentielle persistante. L'hypoparathyroïdie transitoire était notée chez (14%). Les goitres plongeants représentent une éventualité assez fréquente. Souvent révélés à l'occasion d'un examen clinique. L'examen tomodensitométrique qui permet l'exploration des espaces peu accessibles à l'imagerie conventionnelle. L'imagerie par résonance magnétique nucléaire paraît constituer une technique d'avenir.
