Forty-four cases of odontalgia are described which are considered to be a painful migraine-like disturbance of the blood vessels of the dental pulp and periodontal membrane. The condition appears to be a manifestation of depression and other personality disorders and responds well to antidepressant drug therapy (75 per cent of the patients). The recognition and proper management of this atypical ondontalgia is of crucial importance in preventing unnecessary surgery.

The present study investigates the relationships between clinical pain relief, physiological and psychological parameters. Out of 50 patients with long-lasting musculoskeletal neck- and shoulder-pain treated with transcutaneous electrical nerve stimulation (TENS), 21 were selected and classified as responders (n = 13) or non-responders (n = 8). Tooth pain thresholds (PT) were measured before and after an experimental TENS treatment and the relative change in PT following the stimulation was calculated. Three psychometric self-inventories were administered: Zung Depression Scale, Spielberger's Trait Anxiety Scale and the Multidimensional Health Locus of Control Scale. Responders (R) and non-responders (NR) differed significantly from each other in the PT measurements as well as on the psychometric scales. NR exhibited higher levels of anxiety and depression, a more pronounced powerful other orientation and no change or a decrease in PT following TENS compared to R. These findings indicate relationships and interactions between physiological and psychological factors in patients with long-lasting pain.

Couvade is a phenomenon, where the expectant father or another relative experiences somatic and/or psychiatric symptoms during a woman's pregnancy. Although epidemiological studies report a frequency of couvade symptoms between 11 and 36% during all pregnancies, psychotic couvade cases are very rare with few case reports. The authors report 2 cases of psychotic couvade and give a psychodynamic interpretation of the cases. They emphasize the important role of ego defect and double identification in the development of the cases. Couvade is a phenomenon, where the expectant father or another relative experiences somatic and/or psychiatric symptoms during a woman's pregnancy. The term couvade was first coined by Tylor in 1865. Somatic symptoms can include indigestion or colic, gastritic symptoms, food cravings, nausea and vomiting, increased or decreased appetite, diarrhea, toothache, headache, itch, muscle tremors, nosebleed or other pains. Abdominal bloating and pseudocyesis have also been reported. Although the psychiatric symptoms most often observed are depression, anxiety, insomnia, irritability, tension and hypochondria there are some reports on psychotic couvade too. In our article we present 2 cases of psychotic couvade.

The pharmacology, pharmacokinetics, efficacy, adverse effects, and dosage and administration of tramadol are reviewed. Tramadol is a synthetic analogue of codeine that binds to mu opiate receptors and inhibits norepinephrine and serotonin reuptake. It is rapidly and extensively absorbed after oral doses and is metabolized in the liver. Analgesia begins within one hour and starts to peak in two hours. In patients with moderate postoperative pain, i.v. or i.m. tramadol is roughly equal in efficacy to meperidine or morphine; for severe acute pain, tramadol is less effective than morphine. Oral tramadol can also be effective after certain types of surgery. Tramadol and meperidine are equally effective in postoperative patient-controlled analgesia. In epidural administration for pain after abdominal surgery, tramadol is more effective than bupivacaine but less effective than morphine. In patients with ureteral calculi, both dipyrone and butylscopolamine are more effective than tramadol. For labor pain, i.m. tramadol works as well as meperidine and is less likely to cause neonatal respiratory depression. Oral tramadol is as effective as codeine for acute dental pain. In several types of severe or refractory cancer pain, tramadol is effective, but less so than morphine; for other types of chronic pain, such as low-back pain, oral tramadol works as well as acetaminophen-codeine. Common adverse effects of tramadol include dizziness, nausea, dry mouth, and sedation. The abuse potential seems low. The recommended oral dosage is 50-100 mg every four to six hours. Tramadol is an effective, if expensive, alternative to other analgesics in some clinical situations.

This study focuses on the influence of trait anxiety and mood variables on changes in tooth pain threshold following two similar methods of somatic afferent stimulation, one familiar (manual acupuncture) and one unfamiliar (low-frequency transcutaneous electrical nerve stimulation [low-TENS]). Twenty-one acupuncture responders, treated for long-lasting orofacial muscular pain but naive to low-TENS, were selected for the study. In an experimental session, acupuncture and low-TENS were randomly given during two periods separated by a rest interval. Tooth pain thresholds (PT) were measured before and after stimulation with a computerized electrical pulp tester. Trait anxiety and depression were assessed with psychometric forms before the experimental session in all patients, whereas momentary mood was assessed in 10 randomly selected patients with visual analogue scales during and after the two types of stimulation. Following acupuncture, the group average PT increased significantly, whereas no significant change was observed following low-TENS. Higher scores on trait anxiety correlated significantly with a low PT increase following low-TENS, and higher ratings of stress correlated significantly with a low PT increase following acupuncture. This indicates that the magnitude of analgesia induced by these methods may be modified by psychologic factors like anxiety and stress.

Alexithymia is a term denoting a deficit in the ability to differentiate emotional from physical states and to identify and describe one's feelings, as well as a preference for external oriented thinking. Alexithymia has been linked with various somatic and psychosomatic diseases, especially with chronic pain. The aim of this study was to evaluate the association between alexithymia and symptoms of temporomandibular disorders (TMD) as well as oro-lingual and dental pain, in a large representative population sample of young adults. The study was a part of the 31-year follow-up study of the Northern Finland Birth Cohort originally consisting of 12058 live births in the year 1966. In 1997, 4893 subjects living in northern Finland or in the capital area, who participated in a field study of the project and later returned a postal questionnaire, made up the sample of this study. Information concerning symptoms of TMD and oro-lingual and dental pain was collected from the subjects. To assess alexithymia, the Toronto Alexithymia Scale-20 (TAS-20) was used. In addition, information about depression, marital status and self-rated health was collected. The proportion of alexithymics (TAS score over 60) was higher in subjects with the most orofacial symptoms than in asymptomatic subjects. In men, alexithymia associated significantly with facial pain, difficulties in mouth opening, oro-lingual pain and dental pain, and in women with pain on jaw movement and dental pain. After adjusting for depression, marital status, and self-rated health, a significant association remained between alexithymia and the symptoms mentioned, except for facial pain in men. It can be concluded that alexithymia is connected with orofacial symptoms. Clinicians treating these symptoms should be familiar with the concept of alexithymia.

The treatment of chronic pain uses drugs from different pharmacological classes. Analgesics are the common basis of these treatments. Peripheral analgesics (or minor analgesics such as paracetamol) and non-steroidal anti-inflammatory drugs are used for moderate pain (grade I of WHO). Major analgesics, opioids, are used for more severe pain (grades II and III). When pain can be related to a precise cause or location, more specific drugs may be used. This is done in migraine, facial pain, muscular spasms, dental pain, local inflammation. Chronic pain of grades II and III is treated with opioids. According to the severity, agents of different powers are used: partial agonists, full agonists of receptors OP3 (mu) and OP2 (kappa). According to other pathological signs linked to pain, coanalgesic drugs may be used in association: psychotropic drugs, either psycholeptic drugs which act synergistically with analgesics and bring their own effects, anxiolytic and/or neuroleptic, or anti-depressants which inhibit the depression state that may be associated with pain. Corticosteroids are also very useful for the numerous effects they induce: inhibition of the inflammation process, CNS stimulation, analgesics in medullary, or plexus compressions and in elevations of intracranial hypertension. Moreover their metabolic effects may be useful in cachectic states. The pharmacological treatment of chronic pain of grades II and III poses the problem of chronic administration of increasing doses of opioids and of their coprescription, of acquired tolerance, of dependence and of toxicity induced by drug accumulation.

The relationship between oral health and anxiety/depression were assessed in a cross-sectional study conducted in 388 Portuguese students from the Health Sciences (age: 21 +/- 3 years, 75% women). Oral health included prevalence of reported tooth pain/gum bleeding, dentist attendance, and dentifrice and dental floss use. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale. Subjects with anxiety or depression had a higher frequency of perceived gum bleeding and reported a higher dentist attendance than normal subjects. On multivariate analysis, anxiety was significantly and independently related to perceived toothache (OR = 2.90, 95% CI: 1.25-6.72) and dentist attendance (OR = 2.15, 95% CI: 1.18 - 3.91) whereas depression was associated with perceived gum bleeding (OR = 4.96, 95% CI: 1.68 - 14.59), and no differences were found regarding teeth brushing or dental flossing. The author concludes that anxiety and depression are related to perceived toothache and gum bleeding, but this association cannot be explained by decreased dental care.

Compared to the other glutamate receptors, progress in the understanding of the functions of kainate receptors (KARs) has lagged behind, due mainly to the relative lack of specific pharmacological tools. Over the last decade subunit selective agonists (e.g. ATPA and 5-iodowillardiine) and orthosteric (e.g. LY382884 and ACET) and allosteric antagonists for KARs that contain GluK1 (GluR5) subunits have been developed. However, no selective ligands for the other KAR subunits have been identified. The use of GluK1 antagonists has enabled several functions of KARs, that contain this subunit, to be identified. Thus, KARs have been shown to regulate excitatory and inhibitory synaptic transmission. In the case of the regulation of L-glutamate release, they can function as facilitatory autoreceptors or inhibitory autoreceptors during repetitive synaptic activation and can respond to ambient levels of L-glutamate to provide a tonic regulation of L-glutamate release. KARs also contribute a component of excitatory synaptic transmission at certain synapses. They can also act as triggers for both long-term potentiation (LTP) and long-term depression (LTD) and rapid alterations in their trafficking can result in altered synaptic transmission during both synaptic plasticity and neuronal development. KARs also contribute to synchronised rhythmic activity in the brain and are involved in forms of learning and memory. With respect to therapeutic indications, antagonists for GluK1 have shown positive activity in animal models of pain, migraine, epilepsy, stroke and anxiety. This potential has now been confirmed in dental pain and migraine in initial studies in man.

Orofacial pain in its broadest definition can affect up to 7% of the population. Its diagnosis and initial management falls between dentists and doctors and in the secondary care sector among pain physicians, headache neurologists and oral physicians. Chronic facial pain is a long term condition and like all other chronic pain is associated with numerous co-morbidities and treatment outcomes are often related to the presenting co-morbidities such as depression, anxiety, catastrophising and presence of other chronic pain which must be addressed as part of management . The majority of orofacial pain is continuous so a history of episodic pain narrows down the differentials. There are specific oral conditions that rarely present extra orally such as atypical odontalgia and burning mouth syndrome whereas others will present in both areas. Musculoskeletal pain related to the muscles of mastication is very common and may also be associated with disc problems. Trigeminal neuralgia and the rarer glossopharyngeal neuralgia are specific diagnosis with defined care pathways. Other trigeminal neuropathic pain which can be associated with neuropathy is caused most frequently by trauma but secondary causes such as malignancy, infection and auto-immune causes need to be considered. Management is along the lines of other neuropathic pain using accepted pharmacotherapy with psychological support. If no other diagnostic criteria are fulfilled than a diagnosis of chronic or persistent idiopathic facial pain is made and often a combination of antidepressants and cognitive behaviour therapy is effective. Facial pain patients should be managed by a multidisciplinary team.
