RESUMEN
Acute calcific longus colli tendinitis is a differential diagnosis of neck pain. Typical presentation consists in a triad of symptoms including acute onset neck pain, neck stiffness and odynophagia. Computed tomography (CT) is the gold standard for acute calcific longus colli tendinitis diagnosis and the main radiological findings include prevertebral soft tissue swelling and the presence of amorphous calcifications. The case involves a 39-year-old female who presented to the emergency department with acute unilateral cervical pain that resulted in acute calcific longus colli tendinitis.
RESUMEN
BACKGROUND: Otological complaints (OC) are highly prevalent in subjects with temporomandibular disorders (TMD) and so is the risk of neck dysfunctions. OBJECTIVE: To evaluate pain, deep neck flexor (DNF) performance, disability, and head and neck posture of individuals with TMD with and without OC. METHODS: In this cross-sectional study, 57 individuals were divided into a group with TMD and OC (n= 31) and a group with TMD without OC (n= 26). Self-reported pain intensity, masticatory and neck muscles pressure pain thresholds, DNF performance, neck disability, and head and neck posture were evaluated. Data were compared between groups using the independent t test and Mann-Whitney test with Bonferroni correction for multiple comparisons. Effect sizes were evaluated using Cohen's index. RESULTS: The TMD with OC group presented less muscle activation [26 (24-28) vs. 24 (24-26) mmHg; p< 0.05], less endurance [105 (46-140) vs. 44 (28-78) points; p< 0.05], and greater neck disability (8.15 ± 5.89 vs. 13.32 ± 6.36 points; p< 0.05). No significant difference was observed in self-reported pain, head and neck posture, or pressure pain thresholds. CONCLUSION: Individuals with TMD with OC presented decreased DNF performance and increased neck disability compared to individuals with TMD without OC.

SUMMARY OBJECTIVE: The aim of this study was to compare the pressure pain threshold and the thickness of the cervical muscles in patients with tension-type headache versus healthy participants. METHODS: An observational, retrospective, cross-sectional study was conducted at the Universidad Europea de Madrid between May and June 2022. Adults aged 18-65 years with tension-type headache diagnosed for more than 6 months were compared to healthy controls. B-mode ultrasound imaging was employed to measure the thickness of the neck stabilizing muscles, longus colli, and multifidus at the C5 and C6 levels, respectively. pressure pain threshold measurements were assessed bilaterally in the following regions: upper trapezius, masseter, temporalis, anterior tibialis, and median nerve. RESULTS: A total of 40 participants (90% females; 36.3±12.9 years, BMI 24.2±3.7 kg/m2) participated in the study. Compared with the control group (n=20), participants in the tension-type headache group (n=20) presented statistically significant lower values in all pressure pain threshold measures. Additionally, the tension-type headache group presented statistically significant lower values in the thickness of the following muscles: right multifidus at rest (1.0±0.2 cm versus 1.3±0.2 cm; p<0.001), left multifidus at rest (1.1±0.1 cm versus 1.3±0.1 cm; p<0.001) and during contraction (1.2±0.1 cm versus 1.5±0.2 cm; p<0.001), left longus colli at rest (1.0±0.2 cm versus 1.2±0.1 cm; p=0.01) and during contraction (1.2±0.2 cm versus 1.4±0.1 cm; p<0.001), and right longus colli during contraction (1.2±0.2 cm versus 1.4±0.2 cm; p=0.02). CONCLUSION: This study concluded that patients with tension-type headache showed lower thickness and lower pressure pain threshold of cervical muscles compared to healthy controls.
RESUMEN
OBJECTIVE: The purpose of this study was to assess the correlation, concurrent validity, and agreement between the isometric cervical force measurements obtained with fixed and portable dynamometers in asymptomatic individuals. METHODS: Fifty asymptomatic individuals performed 3 maximal isometric contractions for flexion, extension, and lateral flexion of the cervical spine using fixed and portable dynamometers. The correlation and concurrent validity for the measurements of the portable and fixed dynamometers were analyzed using Spearman's correlation coefficient and the intraclass correlation coefficient (ICC), respectively. The agreement between the force values of the portable and fixed dynamometers was measured using the Bland-Altman method. RESULTS: Isometric cervical force measurements obtained with the fixed dynamometer and portable dynamometer showed a moderately to highly significant correlation for flexion (rs = 0.74), extension (rs = 0.82), right lateral flexion (rs = 0.74), and left lateral flexion (rs = 0.68). The concurrent validity was moderate to good for all measurements (ICC2,3 = 0.67-0.80). The fixed and portable dynamometers did not agree, with a significant mean difference between the methods of 2.8 kgf (95% confidence interval [CI], 2.1-3.4 kgf) for cervical flexion, 5.3 kgf (95% CI, 4.2-6.4 kgf) for extension, and 9.1 kgf (95% CI, 0.4-2.1 kgf) for left lateral flexion. The limits of agreement were broad for all movements, with errors that varied between 61% and 77% of the mean force obtained with the fixed dynamometer. CONCLUSION: The neck strength measurements obtained with the fixed and portable dynamometers demonstrated high to moderate correlation and had moderate to good comparability for asymptomatic participants. However, they did not agree in that the 2 methods did not provide equivalent measurements, and, therefore, based on these findings, the same equipment should always be used when reassessing an individual.

INTRODUCTION: Infrared thermography has the potential to help assess human head and neck muscles, as thermal variation measurements due to muscle imbalance can contribute to the evaluation and therapeutic follow-up of various clinical conditions in the field of health. OBJECTIVE: This study investigated, with a scoping review, the use of infrared thermography in complementary assessments of human head and neck muscles to determine the extent of research on the topic, what methodologies are used in thermal assessment and thermographic analysis, what regions are assessed, and what results are expected in thermography. METHODS: LILACS, MEDLINE, SciELO, and Web of Science were the databases searched to identify articles published on the topic, with no restriction of language or time of publication. Descriptive, analytical, and experimental observational studies on the assessment of the human head and neck muscle surface temperature with infrared thermography were included. Case studies, case series, methodological accuracy, literature review, animal studies, studies that assessed patients with head and neck cancer, and studies that did not assess head and neck muscle temperature with thermography were excluded. The articles were analysed with a protocol developed by the authors, with data on author, year, country, type of study, sample characterisation, muscles assessed, outcomes investigated, thermal assessment methodology, thermographic analysis methodology and thermography measurements. RESULTS: This review identified and analysed 27 articles. The studies assessed thermal distribution in normal individuals and those with pathologies related to hyper- and hypofunctional head and neck muscle conditions for diagnosis or therapeutic follow-up. The masseter, temporal, digastric, anterior cervical region, orbicularis oris, frontalis, buccinator, suprahyoid, trapezius, sternocleidomastoid and levator scapulae muscles were assessed. Quantitative analyses with area selection tool predominated, considering absolute temperatures and temperature differences. The studies investigated temperature and its relationship with myogenic pain, quantitative assessment of muscle parameters and blood flow velocity. The mean temperature ranged from 32.97°C (±2.21) to 34.90°C, and hyper-radiant and/or asymmetric regions were observed in hyperfunctional conditions and normal subjects after muscle activation. CONCLUSION: Thermography is used in complementary assessments of head and neck muscles, identifying hyper-radiant regions and thermal asymmetry related to muscle tension and activation state. Papers are limited to specific clinical conditions and few muscle groups, besides having great methodological variability.

OBJECTIVE: To evaluate neck pain, disability, and deep neck flexor (DNF) performance of individuals with temporomandibular disorders (TMD). METHODS: Eighty individuals were divided into the following: arthrogenic TMD (n = 40), myogenic TMD (n = 12), and mixed TMD (n = 28). Neck pain intensity, neck disability, and DNF performance were evaluated. RESULTS: Individuals with arthrogenic TMD reported lower intensity of neck pain when compared to mixed TMD (p = 0.01). Individuals with arthrogenic TMD had less neck disability than individuals with myogenic TMD (p = 0.037) and mixed TMD (p < 0.001). A moderate positive correlation was found between neck pain and neck disability (p < 0.001). No differences were found for DNF performance. CONCLUSION: Neck pain and disability differs according to subtype of TMD, but performance of the deep neck flexors does not. Neck pain intensity and neck disability were correlated in patients with TMD.
RESUMEN
OBJECTIVE: To evaluate the sternocleidomastoid and the descending portion of the trapezius muscles in terms of electromyographic activity and pressure pain threshold in women with chronic cervical pain after acupuncture treatment. METHODS: Twenty-five women, aged 18-50 years [(31±3) years], with chronic neck and temporomandibular disorder participated in the study. The electromyographic activity of the sternocleidomastoid muscle and the descending portion of the trapezius muscle were recorded at rest, during shoulder elevation, (left and right) rotation of the neck and crucifix position. Maximum voluntary contraction was used to normalize the electromyographic activity data. The points used for acupuncture were Jiache (ST 6), Xiaguan (ST 7), Quanliao (SI 18), Tinggong (SI 19), Yifeng (TE-17), Fengchi (GB 20), Renzhong (GV 26), Yangbai (GB-14), and points of the lower and upper limbs: Tai chong (LV 3), Zusanli (ST 36), Sanyinjiao (SP 6), Kunlun (BL 60), He Gu (LI 4) and Yanglingquan (GB 34). The treatment course was 10 sessions, 30 min long per session, and twice a week. The final electromyographic activity and pressure pain threshold data collection were performed 15 d after treatment completion. RESULTS: The normalized electromyographic activity and pressure pain threshold data were tabulated and submitted to statistical analysis using t-test (P < 0.05). Significant difference was observed during shoulder elevation for the left trapezius muscle, during neck rotation from the right side to the left, and pressure pain threshold for the trapezius and sternocleidomastoid muscles, bilaterally, after the acupuncture treatment. CONCLUSION: The acupuncture treatment improved the neck muscles in terms of electromyographic activity and increased the tolerance to chronic pain in women.

BACKGROUND: Cervical spine disorders are frequently associated with temporomandibular disorders (TMDs). Although headache is common in TMD, few studies have considered headache regarding the functional performance of the cervical spine in TMD. OBJECTIVES: To evaluate TMD subjects with and without self-reported headache, assess the active and passive range of motion (ROM) of the upper cervical spine (C1-C2) and performance of the deep cervical flexors, and evaluate the correlation of these outcomes with neck disability and temporomandibular pain. METHODS: In this cross-sectional study, we assessed 57 women (40 with TMDs and 17 without TMDs [controls]). The TMD group was divided into 25 and 15 patients with and without self-reported headache, respectively. We assessed the active and passive upper cervical ROMs using the flexion-rotation test (FRT) and muscle performance using the craniocervical flexion test (CCFT). The neck disability index questionnaire and visual analog scale were used to assess self-reported neck disability and temporomandibular pain, respectively. RESULTS: Compared to controls, all TMD subjects showed reduced cervical mobility on flexion/extension movements, reduced FRT findings and worse performance in CCFT (P < .05 all). Additionally, the CCFT and FRT findings were correlated with temporomandibular pain (r = .4 and .5, respectively) and neck disability (r = .3 and .4, respectively). CONCLUSION: Women with TMDs, regardless of self-reported headaches, showed limited flexion/extension ROM, limited upper cervical spine (C1-C2) mobility and poor deep cervical flexor performance. Neck disability and temporomandibular pain showed a moderate correlation with the functional test findings, that is FRT and CCFT, in subjects with TMDs.

Existem muitos procedimentos para o rejuvenescimento da região cervical; os mais invasivos, porém, como a ritidectomia, podem gerar cicatrizes inestéticas relativamente grandes. Em contrapartida, procedimentos pouco invasivos, como os clássicos fios de sustentação absorvíveis, não têm efeito significativo no tratamento das bandas platismais mais evidentes. Visando solucionar o problema da pouca durabilidade relacionada aos fios de sustentação e eliminar a cicatriz submentoniana indesejável causada pela ritidoplastia, descreve-se uma técnica pouco invasiva para tratamento da flacidez cervical, que pode ser usada isoladamente em pacientes com pouca redundância de pele, ou associada ao minilifting nos pacientes com muita flacidez.
There are many procedures for the rejuvenation of the cervical region. Nevertheless, the most invasive ones such as the rhytidectomy can lead to relatively large unaesthetic scars. In contrast, noninvasive procedures such as the classic absorbable lifting threads have no significant effect on the treatment of the most evident platysmal bands. Aiming at solving the problem of short durability linked to the lifting threads and eliminating the undesirable submental scar caused by rhytidoplasty, a less invasive technique is described for the treatment of cervical laxity. This technique can be used isolatedly in patients with small amounts of skin redundancy, or associated to mini face lifts in patients with considerable sagginess.
RESUMEN
OBJECTIVES: The aim of this study was to investigate whether the presence of a natural mediotrusive contact influences electromyographic (EMG) pattern activity in patients with temporomandibular disorders (TMDs). METHOD: Bilateral surface EMG activity of the anterior temporalis (AT), masseter (MM), and sternocleidomastoid (SCM) muscles was recorded in 43 subjects during unilateral chewing and tooth grinding. Thirteen patients had TMD and a natural mediotrusive contact (Group 1), 15 had TMD without a natural mediotrusive contact (Group 2), and 15 were healthy subjects without mediotrusive contacts (Group 3). All subjects were examined according to the Research Diagnostic Criteria for TMD (RDC/TMD). All EMG values were standardized as the percentage of EMG activity recorded during maximum isometric contraction on cotton rolls. RESULTS: EMG activity from all muscles measured showed no significant differences between groups during chewing and grinding. Overall, in all groups, the EMG activity during chewing was higher in the working side than the non-working side in AT and MM muscles. During grinding, these differences were only found in masseter muscles (mainly in eccentric grinding). SCM EMG activity did not show significant differences during chewing and grinding tasks. Symmetry, muscular balance, and absence of lateral jaw displacement were common findings in all groups. DISCUSSION: EMG results suggest that the contribution of a natural mediotrusive occlusal contact to EMG patterns in TMD patients is minor. Therefore, the elimination of this occlusal feature for therapeutic purposes could be not indicated.

Objetivo: Determinar a confiabilidade intra e interexaminadores das medidas ultrassonográficas do músculo longo do pescoço em mulheres com e sem migrânea. Métodos: Trata-se de um estudo transversal, avaliando 20 mulheres com idade entre 20 e 24 anos (22 ± 2). Foram realizadas duas avaliações ultrassonográficas da área de secção transversa (cm2) do músculo longo do pescoço, em repouso e em contração com intervalo de uma semana entre elas, por dois examinadores cegos. Para análise estatística, foram utilizados o coeficiente de correlação intraclasse (ICC) e os limites de concordância. Resultados: A confiabilidade intraexaminador do grupo com migrânea, em repouso e contração, foi excelente à direita e moderada à esquerda; no grupo sem migrânea variou de excelente (0,93) no repouso, à pobre (0,35) na contração. A confiabilidade interexaminadores foi excelente (ICC > 0,75) à direita e à esquerda, no repouso, em ambos os grupos. Na contração, variou de moderada (ICC = 0,71), no lado esquerdo no grupo sem migrânea, à excelente (ICC > 0,75) nas demais mensurações. Foram observados baixos limites de concordância dos intervalos de confiança em todas as medidas. Conclusão: Foram observados baixos limites de concordância, de acordo com o intervalo de confiança, na confiabilidade das medidas ultrassonográficas do músculo longo do pescoço em mulheres com migrânea.

Objective: To determine intra and inter-rater reliability of ultrasonographic measures of the longus colli muscle in women with and without migraine. Methods: This is a cross-sectional study involving 20 women aged between 20 and 24 years (22 ± 2). Two ultrasonographic assessments, conducted one week apart by two blind examiners, were made of the crosssectional area (cm2) of the longus colli muscle, at rest and in contraction. Statistical analysis used the intraclass correlation coefficient (ICC) and limits of agreement. Results: Intra-rater reliability in the group with migraine, at rest and in contraction, was excellent on the right and moderate on the left; in the group without migraine it ranged from excellent (0.93) at rest to poor (0.35) in contraction. Inter-rater reliability was excellent (ICC > 0.75) at rest on the right and left, in both groups. In contraction, it ranged from moderate (ICC = 0.71) on the left in the group without migraine to excellent (ICC > 0.75) in the other measurements. Low limits of agreement were observed for the confidence intervals in all the measures. Conclusion: According to the confidence interval, low limits of agreement were observed, regarding the reliability of ultrasonographic measures of the longus colli muscle in women with migraine.(AU)

OBJECTIVES: There is scarce knowledge regarding the influence of a natural mediotrusive contact on mandibular and cervical muscular activity. The purpose of this study was to analyze the EMG activity of the anterior temporalis (AT) and sternocleidomastoid (SCM) muscles during awake grinding in healthy subjects with or without a natural mediotrusive occlusal contact. METHOD: Fifteen subjects with natural mediotrusive occlusal contact (Group 1) and 15 subjects without natural mediotrusive occlusal contact (Group 2) participated. Bilateral surface EMG activity of AT and SCM muscles was recorded during unilateral eccentric or concentric tooth grinding tasks. EMG activity was normalized against the activity recorded during maximal voluntary clenching in intercuspal position (IP) for AT muscles and during maximal intentional isometric head-neck rotation to each side, for SCM muscles. RESULTS: EMG activity of AT and SCM muscles showed no statistical difference between groups. EMG activity of AT muscle was higher in the working side (WS) than in the non-WS (NWS) in Group 1 during concentric grinding (0.492 vs 0.331, p = 0.047), whereas no difference was observed in Group 2. EMG activity of SCM was similar between working and NWSs in both groups and tasks. Asymmetry indexes (AIs) were not significantly different between groups. DISCUSSION: These findings in healthy subjects support the assumption that during awake tooth grinding, central nerve control predominates over peripheral inputs, and reinforce the idea of a functional link between the motor-neuron pools that control jaw and neck muscles.

Introduction: An approach based on multiple anatomical structures and the use of different surgical strategies seems to achieve more lasting results in cervical rejuvenation surgery. Thus, extended cervicoplasty is an option with favorable results and low complication rates. However, little has been published regarding the durability of the results. This study aimed to objectively evaluate the long-term results obtained with extended cervicoplasty in difficult cases. Methods: Twenty patients, classified as having a "difficult neck," underwent extended cervicoplasty and were followed for 5 years. The results at 1- and 5-year post-operative follow-up were evaluated by eight plastic surgeons, using six objective criteria based on a theoretically ideal neck. The comparison of the results obtained at these time points was performed using a paired Student's t-test, with a level of significance of 5%. Results: There was no significant difference in five of the six items evaluated (p-value ranging from 0.137 to 1.000), in the comparison between the first and fifth postoperative years. Subhyoid depression displayed a significantly better mean score in the fifth evaluation year than that observed in the first year after surgery (p = 0.039): from 5.80 ± 0.25 points (mean ± standard error of the mean) in the first year, to 6.45 ± 0.30 points in the fifth postoperative year. Conclusion: Extended cervicoplasty is an important alternative in the treatment of the neck region, and even provides lasting results in difficult cases.
Introdução: A abordagem de múltiplas estruturas anatômicas e a utilização de diferentes estratégias cirúrgicas parece contribuir para a obtenção de resultados mais duradouros na cirurgia do rejuvenescimento cervical. Para isso, a cervicoplastia ampliada é uma opção com resultados agradáveis e baixos índices de complicações. A durabilidade dos resultados obtidos é, no entanto, pouco discutida na literatura. O objetivo desse estudo é avaliar objetivamente a manutenção dos resultados a longo prazo obtidos com a cervicoplastia ampliada aplicada em casos difíceis. Métodos: Vinte pacientes, classificadas como "pescoço difícil", foram submetidas à cervicoplastia ampliada e acompanhadas por 5 anos. Os resultados do pós-operatório de 1 e de 5 anos foram avaliados por oito cirurgiões plásticos, por meio de seis critérios objetivos vinculados a um teórico pescoço ideal. A comparação entre os resultados obtidos nestes momentos foi realizada por meio do teste t-student pareado, considerando um nível de significância de 5%. Resultados: Não houve diferença significativa em cinco dos seis itens avaliados (valor de p variando entre 0,137 a 1,000), na comparação entre o primeiro e o quinto ano de pós-operatório. A depressão subhioideia apresentou pontuação média na avaliação do quinto ano significativamente melhor do que aquela observada no primeiro ano após a cirurgia (p = 0,039), passando de 5,80 ± 0,25 pontos (média ± erro padrão da média) no primeiro ano, para 6,45 ± 0,30 pontos no quinto ano de pós-operatório. Conclusão: A cervicoplastia ampliada se valida como alternativa importante no tratamento da região cervical mesmo em casos difíceis, proporcionando a obtenção de resultados duradouros.

Background: Central and peripheral mechanisms may be involved in migraine and tension-type headache pathogenesis, however the role of muscle disorders in their pathophysiological mechanisms remains unclear. Objectives: To assess the association between the presence of migraine or tension-type headache and changes in longus colli muscle dimensions and sternocleidomastoid muscle activity. Method: An observational study with 48 women comparing the following groups: migraine (n=21), tension-type headache (n=16), and control (n=11). The cross-sectional area, lateral and anteroposterior dimensions, and shape ratio of the longus colli muscle were measured using ultrasound. The activation of the sternocleidomastoid muscle was assessed by signal amplitude and the decline in median frequency using surface electromyographic analysis. Results: The dimensions of the longus colli muscle did not differ between groups (p>0.05). Post-test analysis showed lower sternocleidomastoid muscle activation on both sides, at the onset of contraction, in the group with tension-type headache when compared to the control group {right sternocleidomastoid [tension-type headache: 0.39 (0.30-0.49); control: 0.58 (0.42-0.76); p=0.026] and left sternocleidomastoid [tension-type headache: 0.39 (0.31-0.48); control: 0.60 (0.42-0.79); p=0.039], Tukey's post hoc test}. There was no difference between the three groups in sternocleidomastoid muscle activation, on both sides, at the end of contraction (p>0.05). Intergroup analysis showed no difference in the rate of decline in median frequency (p>0.05). Conclusion: The group with tension-type headache exhibited less activation at the onset of sternocleidomastoid muscle contraction. No association was observed between the presence of headache and alterations in longus colli muscle dimensions, median frequency, and sternocleidomastoid muscle activation at the end of contraction. .

OBJECTIVE: This study evaluated the effect of a natural mediotrusive contact on the electromyographic (EMG) activity of the anterior temporalis and sternocleidomastoid muscles during chewing in healthy subjects. MATERIALS AND METHODS: The study sample included two groups of 15 subjects each (Group 1: with natural mediotrusive contact; Group 2: without natural mediotrusive contact). Bilateral surface EMG activity was recorded on anterior temporalis and sternocleidomastoid muscles during unilateral chewing of a half cookie and unilateral chewing of a piece of apple. Anterior temporalis and sternocleidomastoid muscle activity was normalized against activity recorded during maximal voluntary clenching in intercuspal position and maximal intentional isometric head-neck rotation to each side, respectively. The partial and total asymmetry indexes were also calculated. Data were analyzed using Mann-Whitney, Wilcoxon and unpaired t-test. RESULTS: EMG activity of anterior temporalis and sternocleidomastoid muscles showed no significant difference between the groups. EMG activity of anterior temporalis was similar between working and non-working sides during chewing in both groups. EMG activity of sternocleidomastoid muscle was higher in the working side than in the non-working side in Group 2 subjects. Asymmetry indexes were not significantly different between groups. CONCLUSIONS: The similar EMG pattern and asymmetry indexes observed suggest the predominance of central nervous control over peripheral inputs on anterior temporalis and sternocleidomastoid motor neuron pools.

INTRODUÇÃO: A abordagem da região cervical permanece desafiadora ao longo dos tempos. A platismotomia fechada, proposta por Daher, é uma técnica minimamente invasiva, que oferece uma alternativa viável para abordagem da região cervical, com pequenas taxas de complicações e resultados duradouros ao longo dos anos. Avaliar as recorrências das bandas platismais ao longo dos anos, avaliado os resultados após 7 anos. MÉTODOS: Avaliação fotográfica por um Cirurgião Plástico isento, que não conhecia as pacientes, quanto ao número de recidivas em 7 anos de cirurgia, em pacientes operados em nosso serviço, todas do sexo feminino. A análise foi feita por meio de documentação fotográfica, sendo os resultados classificados em excelentes, satisfatórios e insatisfatórios. Não houve participação das pacientes na avaliação. RESULTADOS: Os índices de recidiva após 7 anos de cirurgia encontrados são semelhantes aos encontrados em técnicas já consagradas. 57% dos casos considerados excelentes, 29% satisfatórios e 14% insatisfatórios. CONCLUSÃO: A técnica da platismotomia fechada é uma alternativa válida, com resultados duradouros, e com a vantagem de ser um procedimento com menos comorbidades quando comparado com as técnicas existentes, mantendo-se os índices de recidiva ao longo dos anos semelhantes com outras técnicas mais invasivas.
INTRODUCTION: The approach of the cervical region has remained challenging over the years. The closed platysmotomy technique, proposed by Daher, is a minimally invasive technique that offers a viable alternative to the approach of the cervical region, with low complication rates and lasting results over the years. The objective is to evaluate recurrent cases of platysmal bands over the years, including 7-year results. METHODS: Photographic assessment was performed by a plastic surgeon blinded to the patient characteristics and the number of recurrences 7 years after surgery in all the female patients who underwent operation in our institution. The analysis was performed based on photographic documentation, and the results were classified as excellent, satisfactory, and unsatisfactory. The assessment did not involve patient participation. RESULTS: The recurrence rates 7 years after surgery were similar to those found in traditional techniques. Of the cases, 57% were classified as excellent; 29%, as satisfactory; and 14%, as unsatisfactory. CONCLUSION: The closed platysmotomy technique is a valid alternative, with lasting results and the advantage of being a procedure with comorbidities fewer than those associated with the existing techniques, displaying similar recurrence rates over the years with other more invasive techniques.

La piomiositis es la infección del músculo estriado. Siendo en conjunto infrecuente, lo es aún menos en los músculos del cuello. Se presenta el caso clínico de un hombre ecuatoriano de 19 años residente en Colombia, en quien se diagnosticó piomiositis del esternocleidomastoideo derecho en estadio dos, con escaso compromiso sistémico. Se documentó ecográfica y tomográficamente absceso asociado. Fue tratado conservadoramente con antibioticoterapia -clindamicina y gentamicina- sin necesidad de drenaje del absceso con adecuada evolución y resolución del cuadro. Se realiza una revisión general de la piomiositis y se revisan los casos publicados en Colombia y en el mundo, específicamente del cuello y del músculo esternocleidomastoideo; se encontró que dicho músculo es el más afectado en el cuello. El primer caso colombiano fue publicado en 1990 y se identificó el Staphylococcus aureus como el patógeno más frecuente, aunque también están implicados otros cocos grampositivos y enterobacterias.
Pyomyositis is an infection of the skeletal muscle, occurring infrequently and to a lesser extent in the neck muscles. This paper presents the case of a 19-year-old Ecuadorian male living in Colombia; he was diagnosed with pyomyositis stage 2 in the right sternocleidomastoid muscle, with little systemic involvement. An echography and computer tomography documented an abscess. He was treated conservatively with just antibiotics (clindamycin and gentamicin), without abscess drainage, leading to good progress and resolution of the illness. This paper presents a general review of pyomyositis, cases reported to date in Colombia and the world, specifically regarding the neck and sternocleidomastoid muscle. The sternocleidomastoid muscle is most frequently involved in the neck; the first report of a case in Colombia was published in 1990 and Staphylococcus aureus has been the most frequent pathogen, although other Gram-Positive Cocci and Enterobacteriaceae have also been involved.
RESUMEN
BACKGROUND: Prevertebral calcific tendinitis results from calcium hydroxyapatite crystal deposits in the longus colli muscles, which induce symptoms similar to some surgically-treated conditions, such as retropharyngeal abscesses. Imaging techniques are critical for accurate diagnosis. PURPOSE: To describe the computed tomography (CT) findings associated with prevertebral calcific tendinitis. MATERIAL AND METHODS: Retrospective analysis performed in an 18-month period, searching for patients with neck CT and reports with diagnosis of "calcific longus collis tendinitis" or "prevertebral calcific tendinitis". CT images and clinical data available in the medical records were analyzed. RESULTS: One hundred and thirty-four examinations were performed in the period studied. Nine patients who fulfilled inclusion criteria were identified and their CT imaging characteristics are presented. Six presented with calcific deposits in the right longus colli muscle. CT matched the clinical pain lateralization in all cases. Eight patients had no significant enhancement post injection of contrast media. CONCLUSION: Prevertebral calcific tendinitis is a cause of acute cervical pain that clinically mimics a retropharyngeal abscess, however on neck CT has a characteristic appearance. Correct identification of this pathologic condition will help avoiding unnecessary invasive procedures.

OBJETIVO: verificar a possibilidade de avaliação da deglutição por análise dos traçados eletromiográficos (EMG), em sujeitos com e sem alterações clínicas da deglutição; buscando características específicas voltadas para associação do exame clínico com a eletromiografia. MÉTODO: 39 sujeitos foram divididos em dois grupos: Grupo pesquisa (GP): 25 com alteração de deglutição; controle (GC): 14 sem alteração da deglutição. Equipamento Miotool 200/400 USB, quatro canais, eletrodos na região submental bilateralmente (supra-hióideos). Avaliado deglutição de saliva e cinco mililitros de água. Os registros EMG foram analisados por três juízes, após fornecidos os traçado EMG. Classificaram-se os registros em: normal (pico único) e alterados (mais de um pico, pico não definido, modificações no onset/offset). Utilizou-se o Teste de igualdade de duas proporções. RESULTADOS: obteve-se grande número de registros com deglutições não esperados em ambos os grupos e para os dois tipos de deglutição. Deglutição de saliva, com maior porcentagem em GP de registros com deglutição alterada, não houve diferença entre os grupos. Deglutição de saliva: GC apresentou registros variados, sem predomínio significativo; GP observou-se predomínio de mais de um pico e menor ocorrência de modificações no onset/offset. Deglutição de água: GC predomínio de pico único e menor ocorrência de mais de um pico; GP predomínio de pico único e menor ocorrência de pico não definido. CONCLUSÃO: análise dos traçados EMG não mostrou características específicas e diferenciadas para os grupos; não refletindo padrões que pudessem caracterizar os registros em sujeitos com e sem alterações clínicas da deglutição. Não foi possível definir correlação entre avaliação clínica e EMG da deglutição.
PURPOSE: to verify the possibility of swallowing evaluation in subjects with and without swallowing disorders by the analysis of electromyographic (EMG) traces, search for specific characteristics and association with clinical examination and electromyography. METHOD: 39 subjects were divided into two groups: research (GP) 25 subjects with swallowing disorders and (CG) 14 without these disorders. Equipment Miotool 200/400 USB, 4 channels, with electrodes bilaterally on the submental region. Swallowing of saliva and of 5ml of water was registered. The EMG records were reviewed by three judges, after provided the EMG traces. The records were classified into normal and abnormal (single peak, more than one peak, not defined peak, changes in the onset/offset). Test of equality of two proportions was used. RESULTS: for both groups it was obtained a large number of records with unexpected swallows. The results for GP showed the highest percentage of altered swallowing of saliva records, but no statistical differences between groups was found. GC presented various types of swallowing records of saliva without significant prevalence; GP presented predominance of "more than one peak". In swallowing of water, GC showed predominance of "single peak" and a lower incidence of "more than one peak" and GP showed predominance of "single peak" and lower incidence of "not defined peak". CONCLUSION: analysis of EMG traces didn´t show specific characteristics and differences for groups, not reflecting patterns that could characterize the records in subjects with and without clinical swallowing. No correlation between clinical and EMG of swallowing was possible.
RESUMEN
OBJECTIVE: To estimate the pressure pain threshold (PPT) of the craniocervical muscles in women with episodic migraine (EM) n=15 and chronic migraine (CM) n=14, and in healthy volunteers (C) n=15. METHOD: A blinded examiner obtained the PPT bilaterally, by pressure algometry, for the following muscles: frontalis, temporalis, masseter, trapezius and sternocleidomastoid. ANOVA (p<0.05) was used for statistical purposes. RESULTS: Contrasted to controls, individuals with EM had significantly decreased PPT values for frontal muscle (EM: 2.01±0.67 vs. C: 2.85±0.71), posterior temporalis bilaterally (right and left, respectively) (EM: 2.72±0.89 vs. C: 3.36±0.72 and EM: 2.60±1.00 vs. C: 3.35±0.85), upper trapezius bilaterally (EM: 2.69±1.00 vs. C: 3.49±0.83 and EM: 2.54±0.93 vs. C: 3.32±0.97) and women with CM: on frontal muscle bilaterally (CM: 2.16±0.52 vs. C: 2.79±0.71 and CM: 2.01±0.67 vs. C: 2.85±0.71) and upper trapezius (CM: 2.66±0.84 vs. C: 3.32±0.97), however, it was not verified differences between PPT values between EM and CM groups. CONCLUSION: PPT is decreased in women with migraine relative to controls. Future studies should explore this parameter as a biological marker of the disease and a predictor of treatment.
OBJETIVO: Estimar os valores de limiar de dor por pressão (LDP) dos músculos craniocervicais de mulheres com migrânea episódica (ME) n=15 e crônica (MC) n=14, e em voluntários controles saudáveis (C) n=15. MÉTODO: O LDP foi obtido bilateralmente por examinadores cegos através da algometria de pressão nos seguintes músculos: frontal, temporal, masseter, trapézio e esternocleidomastóideo. Para análise estatística foi utilizada a ANOVA (p<0.05). RESULTADOS: Em relação aos controles, pacientes com ME apresentaram redução significativa do LDP para os músculos: frontal (ME: 2,01±0,67 vs. C: 2,85±0,71), temporal posterior bilateralmente (direito e esquerdo, respectivamente) (ME: 2,72±0,89 vs. C: 3,36±0,72 e ME: 2,60±1,00 vs. C: 3,35±0,85), trapézio superior bilateralmente (ME: 2,69±1,00 vs. C: 3,49±0,83 e ME: 2,54±0,93 vs. C: 3,32±0,97) e mulheres com MC: no músculo frontal bilateralmente (MC: 2,16±0,52 vs. C: 2,79±0,71 e MC: 2,01±0,67 vs. C: 2,85±0,71) e trapézio superior (MC: 2,66±0,84 vs. C: 3,32±0,97). Entretanto não foram verificadas diferenças entre os valores de LDP entre os grupos ME e MC. CONCLUSÃO: O LDP mostrou-se reduzido em mulheres com migrânea episódica ou crônica em relação aos controles. Em estudos futuros, esse parâmetro pode ser estudado como marcador da migrânea e indicador de efeito de tratamento.
