CLINICAL ASSESSMENT OF THE CERVICAL EXTENSOR MUSCLES DYSFUNCTIONS: A SCOPING REVIEW

Neck pain is a major cause of disability worldwide and frequently associated with changes in muscle function. These changes, which may persist after the symptoms have disappeared, could explain recurrent or chronic neck pain. Given the functional alterations of the cervical extensors muscles (CEM) observed in subjects with neck pain1 , a review of the clinical ways to highlight these deficits is relevant. To identify the various clinical tests assessing CEM dysfunctions in patients with chronic neck pain (CNP)

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Nonpharmacological treatment of reflex syncope

Reflex syncope is a common medical problem. Vasovagal reflex syncope is the most frequent form. Although the prognosis of the disorder is excellent, it may impose substantial changes in life style and cause profound psychological distress. Thus, management of this disorder is an important issue. This chapter, based on a review of the literature and the authors' clinical experience, encompasses the non-pharmacological measures used in the management of reflex syncope. The cornerstone of the nonpharmacological management of patients with reflex syncope is education and reassurance regarding the benign nature of the condition. Patients should be instructed to avoid potential triggers. A tilt table test can be employed to teach the patient to recognize early premonitory symptoms. There are several physical maneuvers (e. g., leg crossing, muscle tensing and squatting) that are effective in combating orthostatic intolerance. For the majority of patients this approach is adequate. Patients with frequent attacks of reflex syncope are advised to increase their dietary salt intake. Exercise training also increases orthostatic tolerance. In highly motivated patients with recurrent syncope, raising the head of the bed to permit gravitational exposure during sleep and prolonged periods of enforced maintenance of the upright posture (tilt-training) can be considered. Preliminary data suggest that water drinking may improve orthostatic tolerance. Abdominal belts may also be effective in highly symptomatic subjects with reflex syncop

Value of history-taking in syncope patients: in whom to suspect long QT syndrome?

Long QT syndrome (LQTS), a potentially fatal disorder, has to be distinguished from non-fatal conditions. Our aim was to investigate whether history-taking can be used in identifying patients likely to have LQTS. We compared the characteristics of a group of LQTS patients with syncope patients presenting at the emergency department (ED) and vasovagal patients younger than 40 years of age. Thirty-two LQTS patients were included. We included 113 patients at the ED and 69 vasovagal patients. Family history of syncope, sudden cardiac death, or cardiovascular disease was found more often in LQTS patients. Palpitations were the only symptom reported more often in this group. Syncope while supine, during emotional stress and associated with exercise was also more common among LQTS. Standing as a trigger was found more often in ED and vasovagal patients. We conclude that a family history for syncope and sudden cardiac death, palpitations as a symptom, supine syncope, syncope associated with exercise, and emotional stress place patients at higher risk for LQTS. These findings should alert physicians to the potentially life-threatening illness of LQTS, and act accordingly by obtaining an electrocardiogram and paying specific attention to the QT interva

Quality of life within one year following presentation after transient loss of consciousness

The purpose of this study was to examine (1) changes in quality of life (QoL) within 1 year after presentation with transient loss of consciousness (TLOC) and (2) which factors are predictive of these changes. This study was part of the Fainting Assessment Study (FAST), which assessed diagnostic strategies in patients with TLOC. Adult patients presenting to Academic Medical Center, Amsterdam, The Netherlands, with TLOC were included in the study. QoL was assessed with the generic Short Form 36 and the disease-specific Syncope Functional Status Questionnaire at presentation and 1 year of follow-up. Of 468 included patients, 82% completed questionnaires at presentation and 72% after 1-year follow-up. QoL improved on 7 of 8 subscales of the Short Form 36 and on all summary scales of the Syncope Functional Status Questionnaire. Older age, recurrence, higher level of co-morbidity, and a neurologic or psychogenic diagnosis were predictive of poorer QoL. In conclusion, QoL in patients with TLOC improves significantly over time. Physicians should particularly pay attention to patients who are older, have recurrent episodes, a neurologic or psychogenic diagnosis, and a higher level of co-morbidity because these patients are vulnerable to a relatively poorer QoL.

Clinical factors associated with quality of life in patients with transient loss of consciousness

INTRODUCTION: Transient loss of consciousness (TLOC) is common and can be lethal. Although the patients with the most prevalent causes of TLOC have a benign prognosis, morbidity is considerable. Aim of this article, therefore, was to compare the generic quality of life (QoL) of patients presenting with TLOC with that of the general population, to compare the disease-specific QoL with that of an American referral sample, and to examine which sociodemographic and clinical factors are associated with QoL in these patients. METHODS: This study was part of the fainting assessment study (FAST), which assessed diagnostic strategies for adult patients presenting with TLOC to the Academic Medical Center Amsterdam, between February 2000 and May 2002. The generic short form-36 (SF-36) health survey and the disease-specific syncope functional status questionnaire (SFSQ) were used to assess QoL. RESULTS: Of 468 included patients, 82% completed the questionnaires. Patients with TLOC scored poorer on all scales of the SF-36 than the Dutch population, with effect sizes ranging from 0.43 to 1.11 (>0.5 = moderate effect; >0.8 = large effect). The SFSQ indicated mean impairment in 33% of the listed activities (such as driving). Female gender, higher level of comorbidity, shorter duration of complaints, having had more than one syncopal episode, and the presence of presyncopal episodes were associated with poorer QoL. CONCLUSION: TLOC seriously affects QoL, especially in patients with a recent onset of clinical symptoms and those suffering from both syncopal and presyncopal episode
