    Background
    Vestibular Schwannoma (VS) is one of the skull base tumors originating from vestibular portion of eighth cranial nerve. Recently, 2 micro-Thulium laser is used in the surgery of some intracranial tumors.
    Objectives
    Assessing the efficacy of 2 micro-Thulium flexible hand-held laser fiber (RevolixjrÒ) in microsurgical removal of VS.
    Materials And Methods
    This retrospective non-randomized study was carried out from July 2012 to November 2015. 39 patients with VS had been operated on with microsurgical technique via retro-sigmoid approach. 2 micro-Thulium-fiber hand-held flexible laser was used for tumor resection in 39 cases. Facial nerves function by House-Brackmann (HB) scale and hearing state were assessed preoperatively and 1 week and 6-month postoperatively.
    Results
    Overall time of surgery changed only in proportion with the size of tumor (185-575 minutes) and was not affected by the use of laser. In 5out of 39cases, preoperative facial nerve palsy HB2, and in one case HB4 (permanent) was observed. On considering 38 cases, at 6-month follow-up facial nerve preservation rate (HB1) was 92.1% (from May 2015 all patients had not postoperative facial palsy). Hearing preservation rate was possible in 12 out of 15 cases with previously acceptable preoperative hearing state (AAO-HNS A and B classes). The mean surgeon satisfaction rate of usefulness of this technic was 2.7 in a 0-3-scale
    Conclusions
    A good functional outcome including facial nerve preservation and hearing preservation was obtained by micro-Thulium-fiber hand-held flexible laser microsurgery.

    Background
    Hypoactive sexual desire disorder is the most common sexual disorder among women, which interferes with their various functions. Activity of brain-behavioral and psychological distress systems are considered among factors affecting sexual function.
    Objectives
    The present study aimed to compare women with hypoactive sexual desire and normal women in terms of brain-behavioral and psychological systems.
    Materials And Methods
    In the present causal-comparative study, 37 women with hypoactive sexual desire and 37 normal women were purposively selected with maximum matching in terms of demographic variables from among eligible women attending health centers across Alborz Province in Iran. Data were collected using the following scales: behavioral inhibitory/activation scales (BIS/BAS) and depression, anxiety, stress (DASS) and were analyzed using multivariate analysis (MANOVA) in SPSS software version22.
    Results
    The results obtained showed that mean score of women with hypoactive sexual desire was significantly lower compared with normal women in brain-behavioral activation system (drive, response to reward and pleasure seeking), but significantly higher in behavioral inhibitory system. Furthermore, women with hypoactive sexual desire obtained higher scores which indicate worse conditions than normal women in the components of psychological distress including anxiety, depression and stress.
    Conclusion
    Women with hypoactive sexual desire have weaker behavioral inhibitory/activation systems and higher levels of anxiety, depression, and stress compared to normal women. Given these results, it is recommended that greater attention be paid to factors such as brain-behavioral and psychological distress systems in prevention and treatment programs for hypoactive sexual desire.

    Background
    Menstrual Migraine (MM) is a subgroup of migraine headache that affect the quality of life of patients in menstrual age. Iron Deficiency Anemia (IDA) is the most common cause of anemia, especially in women of reproductive age.
    Objectives
    To determine the association of iron deficiency anemia with menstrual migraine.
    Materials And Methods
    This descriptive-analytic study was conducted on women with migraine visiting neurology clinics affiliated to Isfahan University of Medical Sciences in late 2015 and early 2016. The demographic data and characteristics of migraine headache were registered in a designed questionnaire. The patients underwent laboratory tests for iron deficiency and anemia. Data were analyzed in SPSS-20 using Chi-square test and independent t-test. Significance level was considered at p
    Results
    Of the 93 migraine patients, 47.3% had Pure MM (31.9% with premenstrual migraine and 15.4% with true menstrual migraine), 40.6% had Menstrual-Related Migraines, and 12.1% had non-menstrual migraines. The frequency of iron deficiency anemia was 51.1%, 40.5% and36.4% in PMM, MRM and non-menstrual migraines (p=0.18). Total frequency of iron deficiency anemia in PMM and MRM groups was 46.2%, which was not significantly different from non-menstrual migraine group (p=0.82). Iron deficiency anemia was significantly higher in migraine patients with aura compared to those without aura (53% vs. 43.2%) (p=0.04).
    Conclusion
    Although iron deficiency anemia was more prevalent among patients with menstrual migraine, but it is not associated menstrual migraine.

    Background
    Cognitive impairment profoundly influences on older adults’ activities and quality of life. Therefore, optimizing and remediating age-associated cognitive decline have great importance.
    Objectives
    To evaluate the effect of 8 weeks (3 day /week) computer based brain training on cognitive performance in old women with Mild Cognitive Impairment (MCI).
    Materials And Methods
    This randomized controlled study was performed in old women with MCI that was measured using the mini-mental state examination (MMSE). Twenty women diagnosed with MCI were divided into two groups of: exercised (trained with computerized brain program for 8 weeks (3 day /week, 30-60 min/day) and control group. Before and after training, reaction time, error number and data processing speed were measured using computer stroop task and digit symbol coding test, respectively. After checking the normal distribution of collected data by Kolmogorov-Smirnov test, the pre and post means difference and differences between groups were analyzed using paired T- test and independent t-test respectively.
    Results
    Brain training lead to a significant reduction in reaction time (p=0.001), error number (p=0.002) and increase in data processing speed (p=0.011) compared with pre-test values. Also, there were significant differences between experimental and control groups in reaction time (p=0.001), error number (p=0.007) and processing speed (p=0.013).
    Conclusion
    The findings indicate the efficacy of computer based brain training program on improving the reaction time, error number and processing speed in elderly women diagnosed with MCI and also reflects the plasticity of old brain for challenging to learn new tasks.

    Background
    Irritable bowel syndrome (IBS) is a functional disorder of the lower gastrointestinal (GI) tract caused by stress and is also is associated with anxiety and depression which may benefit from a treatment such as mindfulness.
    Objectives
    to determine the effectiveness of the mindfulness in decreasing the anxiety and depression in the patients suffering from IBS.
    Methods
    The research design was based on single-subject. Three IBS patients diagnosed by Rome-II criteria participated in this treatment project in Tabriz in 2015 voluntarily and with their personal consent. Eight sessions of Mindfulness-Based Stress Reduction (MBSR) were held for them individually. Beck Anxiety Inventory (BAI) and Beck Depression Inventory-II (BDI-II) were used before starting the treatment and at the end of the second, fourth, sixth and eighth sessions regarding to their intensity of anxiety and depression.
    Results
    The anxiety and the depression scores of each subject were decreased in post-test comparing with pre-test. The percentage of the three patient's remission regarding to the anxiety by BAI were 86.67, 56.52 and 70.59 percent and the remission percentage average was 65.25. The percentage of remission regarding to the depression by BDI-II were 35.29, 65.12, 95.24 respectively, and the average percentage of the remission was 57.14.
    Conclusion
    Based on the research findings, the treatment education and MBSR had the positive impact on decreasing the anxiety and e depression of the patients suffering from IBS.

    Background
    Multiple sclerosis (MS) is known to affect essentially the central nervous system; however, peripheral nerve involvement, as an additional cause of disability, has been recently noticed.
    Objectives
    This study was aimed to perform detailed electrodiagnostic assessments in MS patients to evaluate peripheral nervous system involvement.
    Materials And Methods
    A total of eighty MS patients were evaluated for probable peripheral nerves involvement in a cross sectional study from August 2012 to August 2013.Patients with evidence of radiculopathy, diabetes, uremia, and anemia or cobalamin deficiency had been excluded. Clinical disability was ascertained by applying Expanded Disability Status Scale (EDSS) score. All electrodiagnostic assessment was performed by a single expert operator. Demographic parameters and paraclinical findings including MRI plaques were recorded. The data were analyzed in SPSS version 19applying the paired t-test and Mann-Whitney U test.
    Results
    The sural nerves showed the most consistent finding of abnormal conduction velocity (30%). The most frequent amplitude disturbance was observed in the peroneal nerves (10%). We did not find a significant association between abnormal findings and EDSS or MRI plaques (p
    Conclusion
    Peripheral nerve involvement was seen in MS patients, without significant relationship with physical disability and MRI plaques. On the other hand, disease duration, age and male gender were associated with peripheral nerve abnormalities.

    Pneumorrhachis (PR), which involves the entrapment of air or gas within the spinal canal, is a rare clinical entity. The pathogenesis and etiology of this uncommon entity vary and may present a diagnostic challenge. Air in the spinal canal can be divided into primary and secondary PR, extra- or intradural PR and etiologically classified as iatrogenic, traumatic and non-traumatic. PR is typically asymptomatic but can be symptomatic–by itself or by its underlying pathology. The latter, although often severe, might be concealed and must be carefully examined to facilitate adequate patient treatment. Here we report a rare case of traumatic PR in a 28-year old man following a motor vehicle accident in northern Iran, who sustained paraplegia and sphincter dysfunction without any laceration and wound in the spinal area.
