Evidence has begun to accumulate that suggests there may be gender differences in the presenting symptoms of acute coronary syndromes (ACS). Identification of gender differences has implications for both health care providers and the general public. Women should be instructed as to the symptoms expected with ACS on the basis of evidence obtained from studies that include both sexes. Twelve studies that identified symptoms of ACS for both women and men were identified through a review of the literature. In several of the studies, which included all types of ACS, women had significantly more back and jaw pain, nausea and/or vomiting, dyspnea, indigestion, and palpitations. In a number of the studies, which solely sampled patients with acute myocardial infarction, women demonstrated more back, jaw, and neck pain; nausea and/or vomiting; dyspnea; palpitations; indigestion; dizziness; fatigue; loss of appetite; and syncope. Men reported more chest pain and diaphoresis in the myocardial infarction sample. Results of these studies showed that women and men experienced the same symptoms with ACS. However, in some studies there were gender differences in the proportion of symptoms. Given the current state of the science, definitive conclusions regarding gender differences in the symptoms of ACS cannot be drawn. Further study is urgently needed to clarify and expand on these findings.

The modified Stroop task was presented to 48 patients with a Whiplash Associated Disorder (WAD) and 48 healthy matched controls to investigate possible attentional impairments in relation to state related factors (headache, neck pain, fatigue, tension and state-anxiety). It was expected that performance on the Stroop task is negatively influenced by these state related variables. Confirming the expectations, the results showed that response latencies increase for Subtasks 1 through 4, for both groups. In addition, WAD patients performed significantly worse on all subtasks. There was a significant interaction between the two groups and the four subtasks. The results revealed signs for interference susceptibility or reduced capacity to shift attention on the modified Stroop task. The results concerning the influence of state variables indicated that the intensity of headache was significantly related (demonstrating a worsening) to Stroop task performance in the WAD-group. It was concluded that WAD patients exhibit a general slowing of information processing, especially on tasks that require controlled attention. There are signs for subtle deficits in focused attention. The intensity of headache seems to play an important influence on attentional functioning. Clinical implications are discussed.

'Maqianzi' (the dried ripe seed of Strychnos nux-vomica L.) contains 1.0-1.4% each of strychnine and brucine. After processing to reduce its toxicity, 'maqianzi' was used as a herbal remedy for rheumatism, musculoskeletal injuries and limb paralysis. A 42-year old woman with neck pain was prescribed 15 g of 'maqianzi' to be taken in two doses at 7 hours apart, although the recommended dose was 0.3-0.6 g. She was apparently well after drinking the first of two bowls of 'maqianzi' decoction. One hour after she drank the second bowl of herbal decoction, she suddenly developed tonic contractions of all her limb muscles and carpopedal spasm lasting 5 min, difficulty in breathing, chest discomfort and perioral numbness. The second bowl of decoction probably became more concentrated because of evaporation of water during continued boiling and contained a larger amount of 'maqianzi'. On arrival in the hospital 1 hour later, she complained of muscle pain and tiredness. She was found to have hyperventilation and weakness of four limbs, with muscle power of grade 5(-)/5. All her symptoms gradually subsided over the next few hours. This case illustrated that 'maqianzi' can cause strychnine poisoning even after processing, especially when the recommended dose is greatly exceeded. In any patient with 'unexplained' muscle spasms or convulsions, strychnine poisoning should be included in the differential diagnosis and they should be asked about the use of herbal medicines.

Despite the evidence of greater fatigability of the cervical flexor muscles in neck pain patients, the effect of unilaterality of neck pain on muscle fatigue has not been investigated. This study compared myoelectric manifestations of sternocleidomastoid (SCM) and anterior scalene (AS) muscle fatigue between the painful and non-painful sides in patients with chronic unilateral neck pain. Myoelectric signals were recorded from the sternal head of SCM and the AS muscles bilaterally during sub-maximal isometric cervical flexion contractions at 25% and 50% of the maximum voluntary contraction (MVC). The time course of the mean power frequency, average rectified value and conduction velocity of the electromyographic signals were calculated to quantify myoelectric manifestations of muscle fatigue. Results revealed greater estimates of the initial value and slope of the mean frequency for both the SCM and AS muscles on the side of the patient's neck pain at 25% and 50% of MVC. These results indicate greater myoelectric manifestations of muscle fatigue of the superficial cervical flexor muscles ipsilateral to the side of pain. This suggests a specificity of the effect of pain on muscle function and hence the need for specificity of therapeutic exercise in the management of neck pain patients.

A seventy-one-year-old woman was hospitalized with a suspicion of deep neck infection and poor general health. She had been receiving treatment for hepatitis, diabetes mellitus, and cardiac failure and had a history of tooth ache and severe neck pain lasting for the past 10 days. She had been admitted to another center where she had received antibiotic treatment for five days for widespread swelling in the neck and lower extremities, fatigue, and difficulty in breathing and swallowing. Upon admission, computed tomography showed gas formation in the neck and facial regions. Prompt abscess drainage was performed and intense treatment with antibiotics was continued. Despite all efforts, the patient died on the second day of hospitalization from cardiopulmonary arrest. This case emphasizes how urgent drainage is when gas formation is detected in deep neck infections, with inevitable poor prognosis with antibiotic treatment alone.

There have been recent advances in the rehabilitation of the muscles that control the head and neck. These advances are based on evidence of specific neck muscle dysfunction in individuals with persistent head and neck pain. Traditional rehabilitation strategies have focused predominantly on muscle strength and endurance under high loads. New evidence suggests that in people with neck pain there are underlying neuromuscular problems that may require more immediate attention and may not be adequately addressed by simple strength and high-load endurance retraining. Evidence of altered coordination between the deep and superficial neck muscles, greater neck muscle fatigue under sustained low loads, and deficits in kinaesthetic sense have been identified in symptomatic individuals. There is evidence to indicate that addressing these muscle control problems, with specific gentle exercise strategies, results in a reduction in neck pain and associated symptoms.

Fatigue is a symptom that is frequently found in chronic pain patients with low back pain and/or neck pain. At the present time, no specific psychopharmacological treatment for this problem has been identified. Modafinil is a wakefulness-promoting agent that the FDA has approved for the treatment of excessive daytime sleepiness associated with narcolepsy. There have been reports on the use of modafinil for the treatment of fatigue in various neurological syndromes. This literature is reviewed. As such, modafinil treatment was initiated for a patient with severe fatigue associated with chronic low back pain and neck pain. There was dramatic improvement in fatigue and associated function. This case is described. It is the first such case report in the literature. The significance of this finding to the treatment of pain-associated fatigue is discussed.

Recognizing similarities and differences in symptom experiences of acute myocardial infarction (AMI) between men and women has implications for both health care providers and the general public. Rapid accurate diagnosis is necessary to implement timely lifesaving treatment. The purpose of this article is to critically review and evaluate studies that have compared symptoms of AMI between men and women. Research to date has demonstrated that during AMI, women are more likely than men to report shortness of breath, nausea, vomiting, back pain, jaw pain, neck pain, cough, and fatigue, but less likely than men to report chest pain and sweating. However, the findings were inconsistent across studies. These inconsistent findings could be attributable to methodological issues such as collecting data from medical records, small sample sizes, and controversial eligibility criteria for studies. More studies are needed to confirm gender differences in symptom experiences of AMI.

The mechanisms of pain causation in fibromyalgia (FMS) and chronic shoulder/neck pain (SNP) are still debated. We wanted to compare muscle activity and pain development during and after low-grade mental stress in FMS and SNP patients. Twenty-three women with FMS, 29 women with chronic SNP and 35 healthy women performed a stressful task lasting 60 min followed by a 30 min recovery period. We recorded surface electromyography over the trapezius, neck, temporalis and frontalis muscles. Subjects reported their pain at the corresponding locations together with the development of fatigue and perceived tension. Significant differences between FMS and SNP groups were not observed either for muscular or subjective responses. SNP patients and controls responded with more pain in the trapezius and neck regions than in the forehead, in contrast to FMS patients who had a more generalized pain response. Development of pain, tension and fatigue was not related to muscle activity for any group. We conclude that FMS and SNP patients have similar pain and electromyographic responses. The results suggest that similar pathophysiological mechanisms are involved although the responses are more generalised in FMS than in SNP patients. Muscular activity did not explain the pain which developed during the stressful task for either group. Pain lasted longer during recovery in both FMS and SNP patients compared to healthy controls, possibly a result of disease-related sensitisation in pain pathways.

Poor posture has been suggested as one of the main factors contributing to the high prevalence of neck pain in video display unit (VDU) users, but no clear association between pain and any particular resting neck posture has been found. Postural awareness of the neck, as indicated by the repositioning accuracy, may therefore be an appropriate measure and potentially useful assessment tool. The objective of this study is to examine whether posture and fatigue affect the head repositioning ability in typical VDU usage. A group of 20 healthy participants reproduced a normal comfortable posture for forward, upright and backward chair back inclinations in random order both before and after fatigue of the upper trapezius muscles. Ten repetitions of the posture were recorded for 2 s each, and the angular and translational deviations from the original head position were measured with regard to the external environment (head in space repositioning) and with regard to the trunk (head on trunk repositioning). Analysis by repeated measures ANOVA showed significant effects and interactions of fatigue and chair back inclination on the repositioning errors in the sagittal plane, which typically showed systematic trends towards certain postures rather than random errors around a mean position. While further work is required to examine the ergonomic impact of impaired repositioning ability, head repositioning is sensitive to ergonomic factors such as seating configuration and fatigue, and may therefore be a useful tool for evaluation of static working postures.
