Review Comparative Study
[Pathophysiology and treatment of trigeminal autonomic cephalalgias].
Trigeminal autonomic cephalalgias (TACs) are a group of primary headache disorders, which are characterized by strictly unilateral pain, together with ipsilateral cranial autonomic symptoms. TACs include cluster headache (CH), paroxysmal hemicrania (PH) and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT syndrome). ⋯ TACs show differences not only in the length and frequency of attacks but also in the response to drug treatment. It is important to recognize and differentiate between these syndromes because they react very well, but very selectively to therapy.

Review Comparative Study
[Migraine and hormones: what can we be certain of?].
Women suffer from migraine far more frequently than men. This sex difference during the reproductive years is considered to result from additional trigger factors, such as the fluctuating hormones of the menstrual cycle and with the reproductive milestones of women. The role of the female hormones on migraine is illustrated by the phenomenon of menstrual migraine, and the changes in the clinical course of migraine with menarche, pregnancy, menopause and the external application of hormones. In summary, epidemiological, clinical and experimental studies document a substantial influence of female sex hormones on the pathophysiology of migraine headache.

Review Comparative Study
[A clinical challenge. Pragmatic treatment of migraine and concomitant depression].
The association of migraine and depression has been confirmed in numerous studies and it has been suggested that both diseases influence each other in a bidirectional way. As the conventional antidepressants mostly aggravate a pre-existing depression, treatment of both is a demanding task and should be planned in an interdisciplinary setting with neurologists and psychiatrists experienced in pain management. The pharmacological therapy is mainly based on a modulation of the serotonergic and noradrenergic systems and non-pharmacological treatment is also incorporated. ⋯ A combination of several antidepressants with acute acting antimigraine drugs can provoke potentially threatening side effects, however, these possible side effects should not lead to suboptimal treatment of patients with depression and concomitant migraine. The current data on the antimigraine effects of common antidepressants are reviewed and advice for the preventive treatment of migraine with concomitant depression is given. Additionally, hazardous interactions and preferable drug combinations are listed.

The platinum derivative oxaliplatin is widely used in colorectal cancer. Its side effects differ from those of the other platinum compounds cisplatin and carboplatin. ⋯ It is believed that HES is the result of peripheral nerve hyperexcitability as a consequence of voltage-gated sodium channel dysfunction, which may be caused by calcium level imbalance. Therapeutic options for HES are the administration of calcium and magnesium, the serotonin and noradrenaline reuptake inhibitor (SNRI) venlafaxine and the thiophosphate amifostine.

Over the last decades, functional imaging studies have fostered our knowledge of cerebral pain processing in humans. A lively interest has been focussing on possible opioidergic mechanisms of pain transmission and modulation. Today, reliable knowledge of the in vivo distribution of opioid receptors in healthy human subjects is available from positron emission tomography (PET) studies of opioidergic neurotransmission. ⋯ Thereby, the ACC apparently executes cortical top-down control on brainstem structures in (exogenous) pharmacological opioid analgesia. In addition, accumulating evidence suggests that non-pharmacological treatment approaches also utilize similar endogenous opioid dependent pathways to exert pain modulation. This article summarizes our current knowledge of PET studies of the opioidergic system and outlines future perspectives.
