There is convincing evidence that acupuncture (AP) is effective for the treatment of postoperative and chemotherapy-induced nausea/vomiting, as well as postoperative dental pain. Less convincing data support AP's efficacy for chronic pain conditions, including headache, fibromyalgia and low back pain. There is no evidence that AP is effective in treating addiction, insomnia, obesity, asthma or stroke deficits. AP seems to be efficacious for alleviating experimental pain by increasing pain thresholds in human subjects and it appears to activate analgesic brain mechanisms through the release of neurohumoral factors, some of which can be inhibited by the opioid antagonist naloxone. In contrast to placebo analgesia, AP-related pain relief takes some time to develop and to resolve. Furthermore, repetitive use of AP analgesia can result in tolerance that demonstrates cross-tolerance with morphine. However, it appears that not all forms of AP are equally effective for providing analgesia. In particular, electro-AP seems to best deliver stimuli that activate powerful opioid and nonopioid analgesic mechanisms. Thus, future carefully controlled clinical trials using adequate electro-AP may be able to provide the necessary evidence for relevant analgesia in chronic pain conditions, such as headache, fibromyalgia, irritable bowel syndrome and low back pain.

Nasal congestion, one of the major disease features of rhinitis, is induced by the filling of venous sinusoids causing mucosal engorgement with resultant obstruction of nasal airflow. The only available drugs that directly target the underlying vascular features driving nasal obstruction are the sympathomimetic alpha-adrenoceptor agonists due to their vasoconstrictor action. However, standard decongestants are nonselective alpha-adrenoceptor agonists, which have the potential for side-effects liabilities such as hypertension, stroke, insomnia and nervousness. In the present study, the effects of nonsubtype selective alpha(2)-adrenoceptor agonists BHT-920 and PGE-6201204 were evaluated in several isolated nasal mucosa contractile bioassays including dog, pig and monkey, and in a real-time tissue contractility assay using isolated pig nasal explants for BHT-920. The decongestant activity of PGE-6201204 was evaluated in vivo in a cat model of experimental congestion. Our results showed that alpha(2)-adrenoceptor agonists (1) contract nasal mucosa of different species, (2) exert a preferential vasoconstrictor effect on the capacitance vessels (veins and sinusoids), and (3) elicit decongestion. In conclusion, a selective alpha(2)-adrenoceptor agonist causing constriction preferentially in the large venous sinusoids and veins of nasal mucosa and producing nasal decongestion is expected to show efficacy in the treatment of nasal congestion without the characteristic arterio-constrictor action of the standard nonselective sympathomimetic decongestants.

The 59 year-old, high-qualified male patient had been treated for psychiatric illness due to depressive symptoms, "pathological crying", amplified somatic style and severe insomnia. Earlier he had one depressive episode. There was no psychotrauma detected to cause these symptoms and no neurological symptoms, either. The clinical appearance was psychotic depression, so combined antidepressant, anxiolytic, hypnotic, and antipsychotic therapy was started. The MAWI examination showed mild intellectual deficit, so cerebral MRI was done, also. This examination helped to verify the correct diagnosis: post-stroke depression.

Cortical excitability changes induced by tDCS and revealed by TMS, are increasingly being used as an index of neuronal plasticity in the human cortex. The aim of this paper is to summarize the partially adverse effects of 567 tDCS sessions over motor and non-motor cortical areas (occipital, temporal, parietal) from the last 2 years, on work performed in our laboratories. One-hundred and two of our subjects who participated in our tDCS studies completed a questionnaire. The questionnaire contained rating scales regarding the presence and severity of headache, difficulties in concentrating, acute mood changes, visual perceptual changes and any discomforting sensation like pain, tingling, itching or burning under the electrodes, during and after tDCS. Participants were healthy subjects (75.5%), migraine patients (8.8%), post-stroke patients (5.9%) and tinnitus patients (9.8%). During tDCS a mild tingling sensation was the most common reported adverse effect (70.6%), moderate fatigue was felt by 35.3% of the subjects, whereas a light itching sensation under the stimulation electrodes occurred in 30.4% of cases. After tDCS headache (11.8%), nausea (2.9%) and insomnia (0.98%) were reported, but fairly infrequently. In addition, the incidence of the itching sensation (p=0.02) and the intensity of tingling sensation (p=0.02) were significantly higher during tDCS in the group of the healthy subjects, in comparison to patients; whereas the occurrence of headache was significantly higher in the patient group (p=0.03) after the stimulation. Our results suggest that tDCS applied to motor and non-motor areas according to the present tDCS safety guidelines, is associated with relatively minor adverse effects in healthy humans and patients with varying neurological disorders.

Insomnia is a common sleep disorder with devastating socioeconomic consequences. Even though there are pharmacological and behavioral treatments for insomnia, most of the patients are treated with medications. However, the long-term use of medications to treat insomnia is questioned and has potential side effects. More and more Americans are seeking complementary/alternative treatments for many conditions including insomnia and there are anecdotal reports/case series of use of acupuncture in treating insomnia. To examine critically the role of acupuncture in treatment of insomnia, we performed a systematic review of published literature. Among the selected studies for review many were clinical case series and few open or randomized clinical trails. Even though several of these studies did not clarify the nature of insomnia (primary vs. secondary), it seemed that many of the subjects enrolled in these studies had co-morbid other psychiatric (depression or anxiety disorders) and/or medical conditions (Hemodialysis, Stroke, Pregnancy). Except for few, several of these studies had methodological limitations. Despite the limitations of the reviewed studies, all of them consistently indicate significant improvement in insomnia with acupuncture. Further methodologically strong, randomized controlled studies with large sample size are needed to assess the usefulness of acupuncture in treatment of insomnia and explore the possible mechanisms underlying the effects of acupuncture on sleep and sleep disorders.

The vascular bed in nasal mucosa of different species, including human, is highly vascularized and an extensive sinusoidal network of large capacitance vessels is present deep within the submucosa. When this network of venous sinusoids is engorged with blood, the swollen mucosa reduces the size of the airway lumen and congestion ensues. Nasal vasculature tone is strongly influenced by the sympathetic nervous system and the only drugs approved specifically to relieve vascular nasal obstruction are alpha-adrenoceptor sympathomimetic agents. Due to their vasoconstrictor action, the sympathomimetic decongestants oppose vasodilation, reducing nasal airway resistance and thus facilitating nose breathing. However, standard decongestants that are non-selective alpha-adrenoceptor agonists are associated with the potential for side-effect liabilities including hypertension, stroke, insomnia and nervousness. We propose than a selective alpha 2-adrenoceptor agonist, by acting preferentially on nasal venous capacitance vessels, will elicit decongestion with a reduced side-effect liability. In the present study, we evaluated the effects of the selective alpha 2-adrenoceptor agonist BHT-920 in a real-time tissue contractility assay using isolated pig nasal explants and in an in vivo cat model of congestion. The vasoconstrictor and decongestant effects of BHT-920 were compared to the non-selective alpha-adrenoceptor agonist epinephrine and the standard decongestant oxymetazoline. Our results showed that the alpha 2-adrenoceptor agonist BHT-920 preferentially contracts venous sinusoids confirming previous observations [Corboz MR, Varty LM, Rivelli MA, Mutter JC, Mingo G, McLeod R, et al. Effects of an alpha 2-adrenoceptor agonist in nasal mucosa. Arch Physiol Biochem 2003;11: 335-6, Corboz MR, Rivelli MA, Varty LM, Mutter J, Cartwright M, Rizzo CA, et al. Pharmacological characterization of postjunctional alpha-adrenoceptor in human nasal mucosa. Am J Rhinol 2005;19: 495-502] and displays decongestion without affecting blood pressure. Therefore, an alpha 2-adrenoceptor agonist, by causing constriction in the capacitance vessels of nasal mucosa, can produce nasal decongestion without the effects on blood pressure observed with the standard selective alpha 1-adrenoceptor and non-selective alpha-adrenoceptor sympathomimetic decongestants.

A task force to develop guidelines for diagnostic evaluation and treatment of sleep disorders in degenerative neurologic disorders and stroke was initiated by the European Federation of Neurological Societies (EFNS). The aims were to provide evidence-based recommendations in the management of sleep disorders associated with degenerative neurologic disorders and stroke. Neurological patients often have significant sleep disorders like sleep-related breathing disorders (SBD), insomnia, sleep-related motor and rapid eye movement behavioral disorders affecting nocturnal sleep and daytime function. A polysomnography (PSG) is usually a diagnostic minimum for the diagnoses of the most commonly reported sleep disorders in patients with neurologic diseases. A full video-PSG/video-EEG-PSG should be considered in patients with nocturnal motor and/behavior manifestations. Respiratory polygraphy has a moderate sensitivity and specificity in the diagnosis of SBD without neurologic diseases, but its value in patients with neurologic diseases has not been evaluated. Oximetry has a poor sensitivity-specificity for the identification of SDB. Continuous and bi-level positive airway pressure devices are the most effective treatment of SDB in patients with neurologic diseases. There is a need for further studies focusing on the diagnostic procedures and treatment modalities in patients with sleep disorders and degenerative neurologic diseases and stroke.

Alcohol dependence and alcohol abuse or harmful use cause substantial morbidity and mortality. Alcohol-use disorders are associated with depressive episodes, severe anxiety, insomnia, suicide, and abuse of other drugs. Continued heavy alcohol use also shortens the onset of heart disease, stroke, cancers, and liver cirrhosis, by affecting the cardiovascular, gastrointestinal, and immune systems. Heavy drinking can also cause mild anterograde amnesias, temporary cognitive deficits, sleep problems, and peripheral neuropathy; cause gastrointestinal problems; decrease bone density and production of blood cells; and cause fetal alcohol syndrome. Alcohol-use disorders complicate assessment and treatment of other medical and psychiatric problems. Standard criteria for alcohol dependence-the more severe disorder-can be used to reliably identify people for whom drinking causes major physiological consequences and persistent impairment of quality of life and ability to function. Clinicians should routinely screen for alcohol disorders, using clinical interviews, questionnaires, blood tests, or a combination of these methods. Causes include environmental factors and specific genes that affect the risk of alcohol-use disorders, including genes for enzymes that metabolise alcohol, such as alcohol dehydrogenase and aldehyde dehydrogenase; those associated with disinhibition; and those that confer a low sensitivity to alcohol. Treatment can include motivational interviewing to help people to evaluate their situations, brief interventions to facilitate more healthy behaviours, detoxification to address withdrawal symptoms, cognitive-behavioural therapies to avoid relapses, and judicious use of drugs to diminish cravings or discourage relapses.

Evidence is reviewed documenting an intimate relationship among restless legs syndrome (RLS) / periodic limb movements in sleep (PLMS) and hypertension and cardiovascular and cerebrovascular disease. Sympathetic overactivity is associated with RLS/PLMS, as manifested by increased pulse rate and blood pressure coincident with PLMS. Causality is far from definitive. Mechanisms are explored as to how RLS/PLMS may lead to high blood pressure, heart disease, and stroke: (a) the sympathetic hyperactivity associated with RLS/PLMS may lead to daytime hypertension that in turn leads to heart disease and stroke; (b) in the absence of daytime hypertension, this sympathetic hyperactivity may predispose to heart disease and stroke either directly or indirectly via atherosclerotic plaque formation and rupture; and (c) comorbidities associated with RLS/PLMS, such as renal failure, diabetes, iron deficiency, and insomnia, may predispose to heart disease and stroke. One theoretical cause for sympathetic hyperactivity is insufficient All diencephalospinal dopaminergic neuron inhibition of sympathetic preganglionic neurons residing in the intermediolateral cell columns of the spinal cord. We cannot exclude the possibility that peripheral vascular, cardiovascular, and cerebrovascular disease may also contribute to RLS/PLMS, and mechanisms for these possibilities are also discussed.

This study is a double-blind randomized controlled trial on the effect of intradermal acupuncture on insomnia after stroke. Hospitalized stroke patients with insomnia were enrolled in the study and were randomly assigned to either a real intradermal acupuncture group (RA group) or a sham acupuncture group (SA group). The RA group received intradermal acupuncture on Shen-Men (He-7) and Nei-Kuan (EH-6) for three days, and the SA group received sham acupuncture on the same points. The effect of acupuncture on insomnia was measured using Insomnia Severity Index (ISI) and Athens Insomnia Scale (AIS) at baseline and three days after treatment. To assess the effect of acupuncture on the autonomic nervous function, the subjects' blood pressure and heart rate variability were monitored. Fifty-two subjects (27 in the RA group and 25 in the SA group) were included in the final analysis. The insomnia-related scales ISI and AIS showed greater improvement of insomnia in the RA group than in the SA group. Moreover, there is a greater reduction of the number of non-dippers and a greater decrease of the LF/HF ratio (heart rate variability) in the RA group than in the SA group. These results indicate that sympathetic hyperactivities were stabilized in the RA group. It can thus be concluded that intradermal acupuncture on Shen-Men and Nei-Kuan is a useful therapeutic method for post stroke-onset insomnia as it reduces sympathetic hyperactivities.
