Effects of Dynamic Neck Sensorimotor Biofeedback Training in Individuals With Mechanical Neck Pain: A Pilot Randomized Controlled Trial.

Mechanical neck pain (MNP) is commonly accompanied by pain-related functional limitations, sensorimotor disturbances, and fear of movement, which together may contribute to persistent disability. This preliminary randomized controlled trial study investigated the short-term effects of dynamic neck sensorimotor-based biofeedback training in individuals with MNP. 20 MNP patients from outpatient clinics were assigned to a biofeedback training group or a control group. The training group underwent dynamic biofeedback exercises twice weekly for 2&#xa0;weeks, whereas the control group performed repeated cervical movements without biofeedback. Outcomes included cervical kinematics as repositioning errors (RPE), movement units (MU), maximal range of motion (ROM), and subjective measures, including pain intensity, Neck Disability Index (NDI), and Fear-Avoidance Beliefs Questionnaire (FABQ). All participants completed post-intervention assessments; adherence in the training group was 100%, with no missing data and no adverse events reported. Within the biofeedback training group, participants receiving biofeedback training demonstrated greater improvements in cervical repositioning accuracy during flexion (51.95%, p&#xa0;=&#xa0;0.04) and extension (46.67%, p&#xa0;=&#xa0;0.02), along with reductions in fear-avoidance beliefs related to physical activity and work (p&#xa0;<&#xa0;0.05); these changes were less apparent in the active control group. Exploratory regression analyses suggested associations between improvements in repositioning accuracy and pain reduction, and between increased cervical range of motion and improvements in fear-avoidance beliefs related to physical activity. These pilot findings suggest that dynamic sensorimotor biofeedback training may improve proprioceptive acuity and fear-avoidance beliefs in individuals with MNP, supporting further evaluation in an adequately powered randomized trial.

[The neck after radical neck-dissection. A follow-up study (author's transl)].

In 200 patients with uni- or bilateral neck dissections the long range cosmetic results, subjective complaints, and the neurologic status were studied at postoperative time intervals between 3 months and 10 years. The main disorders were related to both the absence of resected, tumor-involved structures and to hyperesthesia of the lateral neck skin. The function of the muscle portions of the shoulder was less disturbed than expected, and recovered with some time and training. Cases with bilateral neck dissections showed postoperative edema of the head, being resorbed, with a little persisting submental edema. Postoperative irradiation gave rise to an increasing number of neuralgiform symptoms.

Enhanced effectiveness of adriamycin and bleomycin combined with local hyperthermia in neck node metastases from head and neck cancers.

The results of this study concern the comparison of the clinical effects of adriamycin (ADM) or bleomycin (BLM) alone and combined with local hyperthermia on 15 patients with multiple (29) neck node metastases from head and neck cancers. With repeated low fractional daily doses of drug a significant though transient tumor regression was obtained in 2/8 and in 3/6 of the lesions treated with ADM or BLM alone, respectively. When the drugs were combined with 42-43 degrees C hyperthermia, an overall response, either complete or partial, was seen in all the lesions. Complete regression was observed in 38% (3/8) and 43% (3/7) of the lesions treated with ADM or BLM, respectively, combined with heat. At a 4-month follow-up, 33% (2/6) and 40% (2/5) of the same groups of lesions remained still undetectable. These results suggest that the combined treatment of drugs and local hyperthermia can be advantageously employed in clinical practice for treating local tumors, especially recurrences in previously irradiated areas.

[Regional neck lymph nodes and primary tumors. 1. Neck lymph node metastases].

The metastasis are situated in the primary regional lymphnodes. Preoperative palpation of the neck gives unreliable results. The extent of the primary tumor has no correlation to the occurence of metastasis. When the tumor is localized in the supraglottic, transglottic or in the tongue base region the frequency of metastasis in lymph nodes is approximately equal; more than half of them have metastasis. When the tumor is localised in sinus piriformis or in the marginal region a still higher frequency of metastasis is found.

[Regional neck lymph nodes and primary tumors. 2. The reactive neck lymph node lesion].

Topographic classification of lymphatic nodes with reactive changes and with metastasis makes evident, that the regional lymph nodes have not only changes, caused by inflammation but also by growth of tumor. Thus, the lymph nodes are accomodation of defense and in the second place as an accommodation of discharge. The regional lymph nodes respond independent of the extent of the primary tumor. The regional metastasis are nearly always localized in the center of lymph nodes with reactiv changes. Lymph nodes with follicular lymphatic hyperplasia are situated in the immediate environment of the metastasis. Lymph nodes with sinus-reaction are extended before the metastasis, in direction of lymph discharge. By super imposed projection of the results of histological evaluation of cervical glands with metastasis in the neck, one obtains to some extent an impression of the defense activity by the lymph nodes at the time of the operation.

Responses of Purkinje cells of the cerebellar vermis to neck and macular vestibular inputs.

1. The dynamic analysis of the control exerted by neck and macular vestibular receptors on the cerebellar cortex has been investigated in precollicular decerebrate cats submitted to sinusoidal rotation along the longitudinal axis of the animal at the frequency of 0.026 Hz and at peak amplitudes up to 10 degrees for the neck input and 15 degrees for the macular input. 2. Purkinje (P) cells located in the vermal cortex of the cerebellar anterior lobe, particularly in the longitudinal parasagittal zone which projects to the ipsilateral lateral vestibular nucleus (LVN), showed a sinusoidal modulation of the firing rate in response to sinusoidal stimulation of the neck receptors or the vestibular receptors, the phase of the responses being in most units related to the extreme neck or head position. Mossy fiber (MF) and/or climbing fiber (CF) responses of the same or different P-cells to the two inputs were observed. 3. The sensitivity of the MF-response of the P-cells to the neck input, elicited by sinusoidal rotation of the neck and expressed in per cent of the average firing rate per degree of neck rotation, corresponded on the average to 2.71 +/- 1.67, S.D. This value was significantly higher than that of the MF-response of the P-cells to the macular input elicited by sinusoidal tilt along the longitudinal axis of the whole animal, which correspond to 1.71 +/- 1.01, S.D. 4. Most of the MF-responses of the P-cells to the neck input were characterized by an excitation during side-down rotation of the neck and by an inhibition during side-up rotation, whereas most of the MF-responses of the P-cells to the macular input showed just the opposite behavior, being inhibited by side-down tilt of the animal and excited by side-up tilt. 5. Units which received a convergent input from both neck and macular receptors and showed an antagonistic pattern of response to the two inputs were tested during rotation of the head alone, in order to excite simultaneously the two kinds of receptors. Due to the higher sensitivity of the neck over the macular response, the magnitude of the combined response tended to be similar to the difference between the individual ones. Moreover, the phase of the resulting response was always modified with respect to that of the response to the neck input alone, and became in some instances related to velocity of neck rotation rather than to neck position. 6. These findings indicate that opposite responses to neck and macular inputs occur at corticocerebellar level. However, a final integration of the two inputs, leading to suppression of the conflicting responses, may occur either at medullary (LVN) or at spinal cord level.

Adding Rib Mobilization to Diaphragm Release Techniques in Patients With Non-Specific Neck Pain: Randomized Controlled Trial.

BACKGROUND: Non-specific neck pain (NSNP) is a frequent issue that can negatively affect both mobility and function. Recently, there has been growing interest in newer therapeutic approaches, including rib mobilization and diaphragm release techniques, as potential ways to address NSNP and support better outcomes for those affected. PURPOSE: To find out the immediate effects of how (DRT) combined with (RMT) affects the level of pain and the extent to which patients' functional abilities are improved in cases of NSNP. METHODS: For this prospective RCT, 96 participants aged 20 to 45&#xa0;years were randomly assigned to one of three equal groups based on their pain score (VAS). Group B engaged in (DRT) for 40&#xa0;minutes, three times weekly for 8&#xa0;weeks, in contrast to Group A, which got both RMT combined with DRT. Group C (active control) received advice and some exercises. Measurements were collected before and after the intervention; the primary outcomes included pain severity, evaluated using a visual analog scale (VAS); active neck range of motion (ROM), measured with a cervical range of motion (CROM) device; and neck flexion endurance. Additionally, the secondary outcome of neck-related disability was assessed using the Neck Disability Index (NDI). RESULTS: No statistically significant difference was identified among the three groups at baseline; nevertheless, a treatment effect emerged after 8&#xa0;weeks (p&#xa0;=&#xa0;0.001 and f-value&#xa0;=&#xa0;4.15, &#x19e;2&#xa0;=&#xa0;0.306). A statistically significant time-treatment interaction was seen when comparing the pre- and post-treatment periods in groups A and B (p&#xa0;=&#xa0;0.001, f-value&#xa0;=&#xa0;3.16, &#x19e;2&#xa0;=&#xa0;0.251). CONCLUSION: The addition of rib mobilization to diaphragm release techniques in patients with non-specific neck pain resulted in statistically significant improvements in pain intensity, cervical flexion, right lateral rotation, left lateral rotation, right rotation, and neck flexor endurance, with moderate to large effect sizes for pain reduction and cervical motion. However, no statistically significant differences were observed between groups for cervical extension, left rotation, or the Neck Disability Index (NDI), and only a marginal clinical improvement in NDI was noted in Group A. The observed benefits in the combined intervention group may not be attributable solely to rib mobilization. The increased treatment complexity and greater therapist interaction inherent in the combined approach could also have influenced the outcomes.

The metastatic spread of "head and neck" tumors in men (an autopsy study of 371 cases).

The investigation was performed by using 371 autopsy records collected by the Department of Pathology at Roswell Park Memorial Institute from 1956 till 1967. Only the "head and neck" tumors were taken into consideration. Two hypotheses were tested, i.e. whether metastases diffuse directly from the primary tumor throughout the body or if the metastatic process takes place in steps, requiring, in other words, that one or more organs be seeded first, before any generalized metastasis occurs. It appeared that the lungs and the lymphnodes of the neck are the two organs responsible for generalized metastases in the cancers of the "head and neck" area. The importance of the neck and lungs metastases in disseminating the disease was discussed in the text. It appeared that when metastases are present in the lymphnodes of the neck, the cancer is already generalized with and without metastatic deposits in the lungs. However, the absence of metastases in the neck is no guarantee that the disease is still localized to the "head and neck" area.

The effect of combining visuo-vestibular exercises with manual therapy and exercise on sensorimotor function in chronic neck pain: A randomized controlled trial.

OBJECTIVE: To investigate whether adding visuo-vestibular exercises to standard manual therapy and exercise produces superior improvements in sensorimotor function, pain, balance, and functional disability in adults with chronic neck pain. METHODS: This prospective, randomized controlled trial enrolled 58 adults with chronic neck pain (&#x2265;3 months) allocated to a manual therapy and exercise group (MtE; n&#x202f;=&#x202f;29) or MtE plus visuo-vestibular exercises (MtE-VVE; n&#x202f;=&#x202f;29). Both groups completed 12 supervised sessions over six weeks with a daily home exercise programme. Outcomes were assessed at baseline, 6 weeks, and 12 weeks, and included pain intensity (Visual Analog Scale [VAS]), upper extremity reaction time, computerized posturography, the Neck Disability Index (NDI), and cervical muscle endurance. RESULTS: Fifty-four participants (27 per group) completed the study. Both groups improved significantly across all outcomes (p&#x202f;<&#x202f;0.001). At 12-week follow-up, the MtE-VVE group demonstrated superior outcomes: activity-related pain was reduced by an additional 2.00&#x202f;cm (95% CI: 0.75-3.25; p&#x202f;=&#x202f;0.005), bilateral reaction time improved by 1.70&#x202f;s (p&#x202f;=&#x202f;0.001), eyes-open mediolateral sway decreased by 0.50&#x202f;mm (p&#x202f;<&#x202f;0.001), NDI score was 6.30 points lower (95% CI: 3.42-9.18; p&#x202f;<&#x202f;0.001), and cervical flexion and extension endurance improved by 12.00&#x202f;s and 27.70&#x202f;s, respectively (p&#x202f;&#x2264;&#x202f;0.020). CONCLUSION: Adding visuo-vestibular exercises to standard manual therapy and exercise produces clinically meaningful and sustained improvements in activity-related pain, sensorimotor function, postural control, and functional disability in adults with chronic neck pain, and may be recommended as an effective adjunctive intervention.

Leveraging Interradiomic Feature Relationships for Enhanced Prediction of Distant Metastasis and Characterization of Heterogeneity in Head and Neck Cancer.

PURPOSE: Distant metastasis remains a major cause of treatment failure in head and neck (HN) cancer, highlighting the need for more accurate early risk stratification. This study developed and validated a deep radiomics framework to characterize tumor heterogeneity from pretreatment computed tomography (CT) images and improve prediction of distant metastasis-free survival (DMFS). METHODS AND MATERIALS: This multicenter study included 3421 patients with HN cancer from 4 cohorts across 12 institutions. Radiomics features were extracted from primary tumors and transformed into OmicsMaps, a structured representation that spatially organizes interfeature relationships to facilitate learning of complex prognostic patterns. A convolutional neural network was trained to derive prognostic signatures, which were integrated with key clinical variables to construct an OmicsMap-clinical fusion model for patient risk stratification. Model performance was assessed using the concordance index (C-index) and time-dependent area under the receiver operating characteristic curve (AUC) in the CT Images from Large Head and Neck Cohort (RADCURE), HEAD-NECK-RADIOMICS-HN1 (HN1), and Head-Neck-Positron Emission Tomography-Computed Tomography (HN-PET-CT) cohorts. Radiogenomic analyses using RNA-seq data were conducted in the Cancer Genome Atlas Head-Neck Squamous Cell Carcinoma (TCGA-HNSC) cohort to investigate biological characteristics associated with the imaging-defined risk groups. RESULTS: The OmicsMap achieved C-index values of 0.742, 0.768, and 0.671 in the RADCURE, HN1, and HN-PET-CT cohorts, outperforming the conventional radiomics approach by 5.40%-6.37%. Incorporating clinical variables further improved generalizability, yielding a C-index of 0.864 (HN1) and 0.730 (HN-PET-CT), with time-dependent AUC of 0.727-0.895. The fusion model consistently stratified patients into distinct high- and low-risk groups for both DMFS and overall survival across cohorts (P <.01). Radiogenomic analyses revealed enrichment of immune-related pathways in the low-risk group, whereas the high-risk group exhibited a more aggressive phenotype enriched for proliferation, hypoxia, and epithelial-mesenchymal transition pathways, along with a fibrosis-prone tumor microenvironment characterized by extracellular matrix remodeling. CONCLUSIONS: Modeling interradiomic feature relationships using the OmicsMap representation substantially improves CT-based prediction of DMFS and characterization of tumor heterogeneity in HN cancer, supporting precision risk stratification in clinical oncology.

Next-generation sequencing in head and neck sarcoma: a single-centre institutional experience and review of the literature.

Head and neck sarcomas (HNS) are rare, heterogeneous malignancies representing less than 1% of head and neck cancers. Their complex anatomy and overlapping morphologies pose significant challenges for traditional diagnosis. We aimed to evaluate the clinical utility of next-generation sequencing (NGS) within a tertiary referral centre and synthesise these findings with current global molecular standards. We conducted a retrospective review of an original, previously unpublished, cohort of 12 patients with histologically verified HNS treated at University College London Hospital (UCLH) between 2023 and 2024. Molecular profiling included targeted DNA (RMH200) and RNA-fusion panels. This was supplemented by a qualitative synthesis of 16 key studies (2010-2026) identified through a systematic search strategy. In the institutional cohort, NGS provided definitive diagnostic or therapeutic clarification in 66% of cases (8/12). Key findings included the identification of pathognomonic fusions (such as EWSR1::FLI1, PAX3::MAML3), a novel MAMLD1::VGLL3 fusion, and actionable variants such as BRAF V600E and MYOD1. Furthermore, the formal exclusion of Neurotrophic tropomyosin receptor kinase (NTRK) fusions in some cases allowed for therapeutic streamlining. Literature synthesis aligned these results and emphasised the need for NGS for more accurate diagnosis and adequate treatment. NGS is a clinical necessity in the management of ultra-rare HNS. By transitioning from traditional morphology to high-resolution molecular interrogation, clinicians can resolve diagnostic ambiguity and identify targeted therapeutic pathways. Integration with emerging 2026 standards, including epigenetic classification and liquid biopsy monitoring, represents the future of precision surgery in head and neck sarcoma.

Cobalt-57 bleomycin for imaging head and neck tumors.

Cobalt-57 bleomycin imaging was performed in 11 patients with a history of head and neck cancer. Clinical and scan findings concurred on the presence and extent of tumor in 9 patients (82%); tumor was present in 7 and absent in 2 of the 9. In 2 patients (18%) the scan demonstrated tumor in the neck but failed to show metastatic sites. Cobalt-57 bleomycin images were of good technical quality, with remarkably low background activity at 24 hours after administration. Cobalt-57 bleomycin imaging appears to be a promising technique for evaluating patients with head and neck tumors.

[Tumorscanning of the head and neck malignomas (author's transl)].

Tumorscanning of malignomas and their metastatic nodules in head and neck is an enrichment of diagnostic possibilities. For the examination such substances can be used, which are tumoraffine and well to mark with a radio-isotope. Therefore we have marked the cytostatic drug Bleomycine with 57Co. Scans were performed with the Anger-Camera 4 to 6 hrs after intravenous injection of 1 mCi 57Co-Bleomycine. 60 patients with different malignomas have been examined, 46 with tumor-localization in head and neck, the others in thoraxabdomen. 34 (85%) of the head and neck malignomas could be demonstrated; 21 (81%) were squamous cell carcinomas, 13 (69%) sarcomas. The possibilities of this method are shown; its clinical importance lies in the identification of primary tumors and their metastatic nodules, of relapses and tumorrests as well as the localization of distant metastasises.

Nutritional concepts in the management of the head and neck cancer patient. I. Basic concepts.

Proper nutritional management has assumed an increasingly important role in the care of cancer patients in recent years. Head and neck cancer creates disturbances in host nutritional balances. Profound nutritional depletion and cachexia are induced by local and distant effects of head and neck carcinoma. Radiation, chemotherapy and surgery tend to compromise the host further by compounding these nutritional deficits. This paper reviews the factors responsible for the malnutrition associated with head and neck malignancy, and discusses the current methods available for identifying and following the nutritionally depleted patient.

[Pain-sensation following classic neck-dissection (author's transl)].

Resulting neck-dissection surgery (including curative or conservative intervention) very complex pain-syndromes are next to losses of function at the top of complaints stated. The discussion of the case-reports of 242 patients with unilateral neck-dissection and the reexamination of 28 patients free of recurrence revealed several causes of head- and facial pain. The close relationship of functional disability and pain-sensation is discussed. The recommendation of elective neck-dissection - by critical indication - is supported. Resection of nervus accessorius may be necessary in some cases, immediate reconstruction by nerve sutures is recommended. By post-operative treatment the complaints often can be relieved.

[Cephalic prostheses in femoral neck fractures: Comparison of immediate complications and late functional results of Moore's prosthesis and sealed prosthesis].

In this study the authors compared the mortality of fractures of the neck of the femur treated by femoral prostheses with early walking compared with trochanteric fractures treated by a nail plate and non-weight bearing activity for 2 to 3 months. The mortality in the two series (about 20 per cent) was the same. The authors then compared two series of fractures of the femoral neck, one treated by Moore's prosthesis without cement and the other by an alternative type of femoral prosthesis with cement. They conclude that the mortality was the same in the two groups but that the cemented prosthesis had better functionnal results. Long-term tolerance of the acetabulum was the same in the two types of prosthesis. Total hip replacement is very rarely indicated in recent fractures of the femoral neck.
