RESUMEN
OBJECTIVE: No conventional pharmacotherapy is available for the treatment of psychogenic dizziness in pediatric patients. Adults with psychogenic dizziness are treated with psychiatric medicines as the standard treatment. In children, this treatment is not widely accepted because of the potential for adverse reactions. Instead, Kampo, an alternative medicine, is probably the best choice of treatment. DESIGN: We report herein three of four cases of pediatric psychogenic dizziness successfully treated with Yoku-kan-san-ka-chimpi-hange (YKCH), a traditional Japanese Kampo medicine known to ameliorate psychiatric symptoms. SUBJECTS: YKCH was prescribed to four patients (two boys and two girls) with psychiatric dizziness whose ages ranged from 11 to 15 years. Four weeks after the initiation of treatment, clinical improvement was assessed by the Clinical Global impression-Improvement scale. RESULTS: In three of the four patients, the drug showed some significant effects. The remaining patient could not continue the medication. It is reasonable to assume that YKCH was effective because of its serotonergic mechanism and the improvement of sleep in our patients. CONCLUSIONS: This report is the first to describe the beneficial effects of YKCH in the treatment of pediatric psychogenic dizziness. We conclude that administration of YKCH may be a suitable complementary therapy for pediatric psychogenic dizziness.

Although the nicotinamide nucleotides NAD(H) and NADP(H) are essential for various metabolic reactions that play major roles in maintenance of cellular homeostasis, the significance of NAD biosynthesis is not well understood. Here, we investigated the dynamics of pollen nicotinamide nucleotides in response to imbibition, a representative germination cue. Metabolic analysis with capillary electrophoresis electrospray ionization mass spectrometry revealed that excess amount of NAD+ is accumulated in freshly harvested dry pollen, whereas it dramatically decreased immediately after contact with water. Importantly, excess of NAD+ impaired pollen tube growth. Moreover, NAD+ accumulation was retained after pollen was imbibed in the presence of NAD+-consuming reaction inhibitors and pollen germination was greatly retarded. Pollen deficient in the nicotinate/nicotinamide mononucleotide adenyltransferase (NMNAT) gene, encoding a key enzyme in NAD biosynthesis, and a lack of NAD+ accumulation in the gametophyte, showed precocious pollen tube germination inside the anther locule and vigorous tube growth under high-humidity conditions. Hence, the accumulation of excess NAD+ is not essential for pollen germination, but instead participates in regulating the timing of germination onset. These results indicate that NAD+ accumulation acts to negatively regulate germination and a decrease in NAD+ plays an important role in metabolic state transition.

OBJECTIVE: Vestibular rehabilitation strategies mostly require a long-lasting training in stance conditions, which is finally not always successful. The individualized training in everyday-life conditions with an intuitive tactile neurofeedback stimulus seems to be a more promising approach. Hence, the present study was aimed at investigating the efficacy of a new vibrotactile neurofeedback system for vestibular rehabilitation. STUDY DESIGN: Double-blinded trial. PATIENTS: One hundred five patients who experience one of the following balance disorders for more than 12 months were included in the study: canal paresis, otolith disorder, removal of an acoustic neuroma, microvascular compression syndrome, Parkinson's disease, and presbyvertigo. INTERVENTIONS: Vibrotactile neurofeedback training was performed daily (15 min) over 2 weeks with the Vertiguard system in those 6 tasks of the Standard Balance Deficit Test with the most prominent deviations from the normative values. MAIN OUTCOME MEASURES: Trunk and ankle sway, dizziness handicap inventory, and vestibular symptom score were measured in the verum and placebo group before the training, on the last training day and 3 months later. RESULTS: A significant reduction in trunk and ankle sway as well as in the subjective symptom scores were observed in the verum group. Such an effect could not be found in any of the outcome parameters of the placebo group. CONCLUSION: The vibrotactile neurofeedback training applied in the present study is a highly efficient method for the reduction of body sway in different balance disorders. Because the rehabilitation program is easy to perform, not exhausting, and time saving, elderly patients and those with serious, long-lasting balance problems also can participate successfully.

Data are limited on the role of psychotherapy in the treatment of Ménière disease. We sought to document the effect of a psychotherapeutic technique known as autogenic training on clinical outcome in Ménière disease. Six patients with Ménière disease were studied. Retrospective chart review was conducted. All patients were refractory to conventional therapy and completed a course of autogenic training, which was offered as a complementary treatment. Autogenic training with initial psychological counseling was conducted by a clinical psychologist during 45-min sessions. Outcome measures assessed were the frequency of vertigo and functional levels 2 years after initiation of autogenic training. Functional levels were evaluated according to the 1995 guidelines of the American Academy of Otolaryngology-Head Neck Surgery (AAO-HNS). As a personality measure, we used the Maudsley Personality Inventory (MPI), devised by Eysenck, which measures neuroticism (N), extraversion (E), and propensity to lie (L). Five of six patients showed improved functional level after three to eight sessions of psychotherapy; hearing level did not change. The score of the N scale of the MPI was closely related to the number of psychotherapy sessions. Prognosis was evaluated based on the AAO-HNS reporting guidelines, as follows: A = 3, B = 1, C = 1, F = 1. The value of N in MPI was closely related to the number of psychological counseling sessions (R = 0.97, P < 0.05). In conclusion, autogenic training may enhance the mental well-being of patients with Ménière disease and improve clinical outcome.

We report two cases of patients with schizoaffective disorder with treatment-refractory auditory verbal hallucinations (AVHs) who were successfully treated with sound therapy, which is effective to treat tinnitus. AVHs in both patients were alleviated within about one month, and no recurrence was reported for 31 and 17 months after the sound therapy together with medication. Further studies may confirm the therapeutic value of sound therapy in patients with intractable AVHs.

The term functional somatic syndrome (FSS) refers to several related syndromes characterized chiefly by symptoms, suffering, and disability and the absence of disease-specific, demonstrable structural or functional abnormalities. Dizziness is a common symptom of FSS. Generally, clinical examination in these cases is inconclusive. The complaints of these patients usually persist until a satisfactory treatment is administered. For the treatment of cases with FSS, first, signs of underlying psychological distress should be identified during history taking. It is essential to address the psychosocial aspect in these cases from a medical point of view. Drug therapy with serotonin reuptake inhibitors is therefore prescribed. Next, psychotherapy should be introduced. The final strategy usually is to collaborate with a clinical psychologist or psychiatrist.

INTRODUCTION: Patients suffering from ear discomfort are commonly encountered in the department of otolaryngology. If various clinical examinations do not reveal any objective findings, then the patients are referred to the department of internal medicine or psychiatry. Psychotherapy is recommended in some cases. This paper describes the successful administration of autogenic training in a patient suffering from ear discomfort due to major depression. CASE PRESENTATION: We present a case of intractable depression that was successfully treated with a combination of psychotherapy, administered by a clinical psychologist, and high-dose antidepressant. The patient was a 36-year-old female with hearing discomfort in her left ear. In 2003, she experienced insomnia and an appetite loss, and her condition was diagnosed as major depression along with an avoidant personality disorder. Her depression has not been improved with antidepressant treatment for 3 years in department of psychosomatic medicine. She was referred to our department because of ear discomfort in her left ear. There was no abnormality in her physical examinations. She wanted to be treated in department of otorhinolaryngology. We increased the dose of fluvoxamine maleate up to 200 mg/day, and introduced cognitive therapy and autogenic training by a clinical psychologist. Eventually, her depressive state as well as the hearing complaint was markedly alleviated. CONCLUSION: Autogenic training can be a viable and acceptable treatment option for patients who fail to respond to other therapies. This case emphasizes the importance of autogenic training as a method to control physical symptom of depression.
RESUMEN
BACKGROUND: Patients suffering from dizziness due to vertigo are commonly encountered in the department of otolaryngology. If various clinical examinations do not reveal any objective findings, then the patients are referred to the department of internal medicine or psychiatry. In many cases, the diagnosis is psychological dizziness. Phobic postural vertigo, which was first reported by Brandt T et al in 1994, is supposed to be a type of psychological dizziness. The diagnosis is based on 6 characteristics proposed by Brandt et al. Patients are usually treated with conventional medical therapy, but some cases may be refractory to such a therapy. Psychotherapy is recommended in some cases; however, psychotherapy including autogenic training, which can be used for general relaxation, is not widely accepted. This paper describes the successful administration of autogenic training in a patient suffering from phobic postural vertigo. CASE PRESENTATION: We present a case of a patient who suffered from phobic postural vertigo. A 37-year-old female complained of dizziness. She had started experiencing dizziness almost 3 years She was intractable to many sort of conventional therapy. In the end, her symptom disappeared after introduction of autogenic training. CONCLUSION: Autogenic training can be a viable and acceptable treatment option for phobic postural vertigo patients who fail to respond to other therapies. This case emphasizes the importance of autogenic training as a method to control symptom of phobic postural vertigo.
RESUMEN
BACKGROUND: Psychological stress plays an important role in the onset and course of Meniere's disease. Surgical therapy and intratympanic gentamicin treatment are options for cases that are intractable to conventional medical therapy. Psychotherapy, however, including autogenic training (AT), which can be used for general relaxation, is not widely accepted. This paper describes the successful administration of AT in a subject suffering from intractable Meniere's disease. CASE PRESENTATION: A 51-year-old male patient has suffered from fluctuating right sensorineural hearing loss with vertigo since 1994. In May 2002, he was first admitted to our hospital due to a severe vertigo attack accompanied by right sensorineural hearing loss. Spontaneous nystagmus toward the right side was observed. Since April 2004, he has experienced vertigo spells with right-sided tinnitus a few times per month that are intractable to conventional medical therapy. After four months, tympanic tube insertion was preformed in the right tympanic membrane. Intratympanic injection of dexamethasone was ineffective. He refused Meniett therapy and intratympanic gentamicin injection. In addition to his vertigo spells, he suffered from insomnia, tinnitus, and anxiety. Tranquilizers such as benzodiazepines and antidepressants such as serotonin selective re-uptake inhibitors (SSRIs) failed to stop the vertigo and only slightly improved his insomnia. In December 2006, the patient began psychological counseling with a psychotherapist. After brief psychological counseling along with cognitive behavior therapy (CBT), he began AT. He diligently and regularly continued his AT training in his home according to a written timetable. His insomnia, tinnitus, and vertigo spells disappeared within a few weeks after only four psychotherapy sessions. In order to master the six standard formulas of AT, he underwent two more sessions. Thereafter, he underwent follow-up for 9 months with no additional treatment. He is now free from drugs, including tranquilizers, and has continued AT. No additional treatment was performed. When we examined him six and nine months later for follow-up, he was free of vertigo and insomnia. CONCLUSION: AT together with CBT can be a viable and palatable treatment option for Meniere's disease patients who are not responsive to other therapies.
RESUMEN
Ferritin is a class of iron storage protein composed of 24 subunits. Although many studies on gene expression analyses of plant ferritin have been conducted, the functions and oligomeric assembly of plant ferritin subunits are still largely unknown. In order to characterize the ability to form multimeric protein shells and determine the iron incorporating activity, we produced ferritin homo- and heteropolymers by expressing four cDNAs of ferritin subunits from soybean, sfer1, sfer2, sfer3, and sfer4, using an in vitro protein expression system. Using SDS-PAGE analysis followed by Prussian blue stain, homopolymers of SFER1, SFER2, and SFER3, and heteropolymers of SFER1/SFER2 and SFER1/SFER3 were detected as assembled polymers with iron incorporating activity, whereas only a small amount of SFER4 related homo- and heteropolymer was detected, suggesting that the SFER4 was not competent for oligomeric assembly, unlike every other ferritin. We conclude that certain combinations of plant ferritin subunits can form heteropolymers and that their iron incorporating activities depend on the formation of multimeric protein.

Fibromyalgia, which is relatively rare, may include symptoms of dizziness, vertigo and tinnitus. Subject was 38 years old woman reporting vertigo and whole body pain. Cochleovestibular function was normal. Pain was gradually intensified during her outpatient clinic and she was admitted. Treatments including intramusclular injection of botulinus toxin and intravenous injection of steroid were applied. Psychological counseling and autogenic training were effective in relieving her pain and vertigo. During her admission, several spells of vertigo occurred but no nystagmus was found. The abnormality in proprioception and neural disintegration may be related to vertigo. Treatment should start as early as possible together with psychological therapy.
