Atypical function of auditory sensory gating in children with developmental dyslexia: Investigating its relationship with cognitive abilities.

Impairments of auditory processing are among frequent findings in dyslexia. However, it is unclear how auditory signals are gated from brainstem to higher central processing stages in these individuals. The present study was done to investigate auditory sensory gating in children with developmental dyslexia (DD), and to determine whether sensory gating correlates with performance on behavioural tasks. Auditory sensory gating at P50, N1 and P2 waves was evaluated in two groups including 20 children with DD and 19 children with typical reading development (TRD). Behavioural tests were used to evaluate phonological working memory (PWM) and selective attention abilities. Sensory gating in children with DD was significantly less efficient than their peers at P50, N1 and P2 waves. Lower auditory evoked potential (AEP) amplitudes were found in the DD group. The children with TRD scored better in all the behavioural tests. Relationships were reported between sensory gating at P50, N1, P2 and behavioural performance in the two groups. Children with dyslexia had deficient sensory gating in comparison with controls. In addition, children with dyslexia experienced problems with PWM and selective attention tasks. The function of sensory gating was associated with attentional and PWM performances in this group.

Challenges of and corrective recommendations for healthcare-associated infection's case findings and reporting from local to national level in Iran: a qualitative study.

BACKGROUND: The accuracy of health care-associated infections (HAIs) statistics in many countries is questionable and the main reasons of this inaccuracy are not well-known. The study aim was to explore inhibitors of and corrective recommendations for HAIs case findings and reporting in some of Iran hospitals. METHODS: Sixteen face-to-face interviews and an expert panel were performed with expertise of infection prevention and control (IPC) programs in hospitals, and Deputies of Health and Treatment in medical university and Ministry of Health from Feb 2018 to May 2019. Using conventional content analysis, code, subcategories and categories were developed. RESULT: Three categories emerged including improper structure preparation, conflict of interest, and inadequate motivation. Allocating distinct budget and adequate staff to IPC programs, developing a user-friendly surveillance system and engaging physicians and nurses for HAIs reporting are the main corrective recommendations accepted by the expert panel. CONCLUSION: Despite the improvement in growing case-findings and reporting of HAIs in Iran, there are many challenges which inhibit accurate case finding and reporting of HAIs. So it is necessary to update the structure, system and rules to reach accurate HAIs data in Iran.

The effect of the virtual social network-based psycho-education on the hope of family caregivers of clients with severe mental disorders.

Psycho-education may have a positive effect on family caregivers of clients with mental disorders, and promote positive psychological states such as hope. The present study aims to investigate the effect of virtual social network-based psycho-education on the hope of family caregivers of clients with severe mental disorders. This study is a quasi-experimental research with a control and experimental groups. The participants of the study were 72 family caregivers of clients with severe mental disorders (36 in each group). Data were collected using demographic questionnaire and Adult Hope Scale before the study, immediately after the end of the training (first post-test), and 4 weeks afterwards (second post-test). The experimental group received psycho-education through Telegram App for four weeks. The results of the demographic questionnaire showed that both groups were homogeneous. The results of the Adult Hope Scale indicated that the mean score of both control and experimental groups were statistically significant and increased in the experimental group (P < 0.001). In addition, the changes of hope score in the experimental group were statistically significant in the first post-test than the pre-test, and in the second post-test than the first post-test and pre-test (P < 0.001). The findings of this study suggested that virtual social network-based psycho-education promotes the hopes of the family caregivers of clients with severe mental disorders. Due to the low cost and fast access of people to virtual networks, the content of this educational program can be widely used for family caregivers.

The severity of hypogonadism symptoms and its risk factors among male employees of Tehran University of Medical Sciences.

OBJECTIVES: The current study was conducted to examine the severity of hypogonadism symptoms and their risk factors among the male employees of Tehran University of Medical Sciences (TUMS). METHODS: This cross-sectional study was conducted on 80 male employees aged 40-60 years, with hypogonadism, at TUMS. The participants were selected through census sampling. The data collection tools included the demographic questionnaire and the Aging Male Symptoms (AMS) questionnaire. The participants first completed the demographic questionnaire and then the AMS questionnaire. SPSS statistical software version 22 (Chicago, IL) was used to analyze the data, and one-way ANOVA tests, Pearson's correlation coefficient, and stepwise multivariate logistic regression were applied. RESULTS: Based on our findings, the mean overall score of hypogonadism symptoms was 41.71 ± 9.20. Based on Pearson's correlation coefficient results, there was a statistically significant association between the severity of hypogonadism symptoms and age (p < .001). Furthermore, there were significant associations between the economic status, cigarette consumption and hours of sleep and the severity of hypogonadism symptoms (p < .001). CONCLUSIONS: The current study's results showed that certain factors can affect hypogonadism in males. Thus, it is important to reduce the severity of hypogonadism symptoms and to modify the factors related to this phenomenon.

Self-efficacy of the First-degree Relatives of Patients with Breast Cancer in the Prevention of Cancer: Using the Health Belief Model.

Breast cancer is the most common type of cancer in women. The best method to fight this disease is early diagnosis. The aim of this study was to investigate the effect of education based on the health belief model on self-efficacy of the first-degree relatives of patients with breast cancer. This randomized clinical trial was conducted in Tehran in 2016 on 80 first-degree relatives of patients with breast cancer. After purposive sampling, the subjects were assigned to interventions and control groups using the randomized block design. The data collection tool was a questionnaire including questions about demographic data, health belief model, and self-efficacy. The educational intervention was held during four 90-min sessions. The questionnaires were completed before and 8 weeks after the intervention in both groups. The data were analyzed using the SPSS16 software. The educational intervention led to a significant increase in susceptibility (d = 1.17, 95%CI 0.69, 1.66), seriousness (d = 1.11, 95%CI 0.62, 1.59), benefits (d = 1.58, 95%CI 1.06, 2.09), and significant decrease in perceived barriers (d = - 0.73, 95%CI 0.27, 1.19) scores in the intervention group. The self-efficacy score in the intervention group was increased from 7.58 to 9.20, which was statistically significant (d = 1.72, 95%CI 1.19, 2.25). However, in the control group, there was no significant difference in self-efficacy score before and after the intervention (p = 0.45). The present study confirmed the effectiveness of the health belief model in promoting self-efficacy of the first-degree relatives of patients with breast cancer. Therefore, it is recommended that this education program is implemented for women, especially the first-degree relatives of patients with breast cancer.

Correlation between self-efficacy and self-esteem in patients with an intestinal stoma.

BACKGROUND: Patients with an intestinal stoma experience psychological difficulties, including disturbances in self-efficacy and self-esteem. There is evidence that they are interdependent. AIM: This study aimed to determine the correlation between self-efficacy and self-esteem in patients with an intestinal stoma. METHODS: A descriptive-correlational study was conducted with 155 patients with an intestinal stoma. Participants were selected using convenience sampling. Data were collected using demographic questions, the stoma self-efficacy scale and the Rosenberg self-esteem scale, and analysed using descriptive and analytical statistics. FINDINGS: Seventy-nine men and 76 women took part; the 50-70 years age group had the highest proportion of participants. Regarding diagnosis, 52.26% had cancer and 45.81% had inflammatory bowel disease or related conditions. Pearson's correlation coefficient indicated a positive, significant correlation between total self-efficacy and its dimensions with self-esteem (P<0.001; r=0.54). CONCLUSION: Self-efficacy is positively correlated with self-esteem in patients with an intestinal stoma. It is recommended that educational interventions are planned and implemented to boost self-esteem and self-efficacy in these patients.

Comparison of Single and Combined Effects of Nature Sounds and Foot Sole Reflexology Massage on the Level of Consciousness in Traumatic Comatose Patients: A Randomized Controlled Clinical Trial.

Consciousness disturbances are the most common posttraumatic complications. The purpose of this study was to compare the single and combined effects of nature sounds and foot sole reflexology massage on level of consciousness in traumatic comatose patients. This randomized controlled clinical trial was conducted in 2 teaching hospitals in an urban area of Iran. Samples were 120 traumatic comatose patients who were randomly assigned into control, nature sounds, foot reflexology massage, and nature sounds plus foot sole reflexology massage groups. Patients in all groups received routine care. Interventions were performed twice a day for 2 weeks, each time for 30 minutes. The patients' level of consciousness was assessed using the Glasgow Coma Scale before, 1 week, and 2 weeks after the intervention. The groups had no significant differences in the mean scores of the consciousness level before, 1 week after, and the last day of the intervention. Also, there was a significant difference in the number of patients who regained full consciousness (P = .001) in the intervention groups compared with the control group. Significant differences in the number of days of consciousness were reported in at least one of the groups compared with other groups (P = .001). This difference was significant in the control group compared with the foot reflexology massage group (P = .032), as well as the nature sounds plus foot sole reflexology massage group (P = .001). Single or combined interventions can increase the level of consciousness in comatose patients and reduce the duration of coma.

Impact of an education program on the performance of nurses in providing oral care for mechanically ventilated children.

BACKGROUND: Mechanically ventilated children are prone to pneumonia due to immobilization and lack of laryngeal (cough) reflex and swallowing. Nurses are directly responsible for many clinical approaches used to prevent ventilator-associated pneumonia. OBJECTIVE: The research objective is to determine the effectiveness of the nurse education program on the performance of nurses in providing oral care for mechanically ventilated children. METHODS: This quasi-experimental pretest-posttest design was conducted on 100 nurses (50 in each of the control and intervention groups) in pediatric intensive care units (PICU) in Tehran, 2015. The research tools included a demographic form and three checklists for evaluation of performance according to the clinical practice guidelines for the oral health status of children in PICU. Before intervention, the performance of nurses in both groups was observed at three stages and three different shifts, using an observational checklist. After one month, their performance was observed again with the same checklist at three stages and three different shifts in the PICU. The training was done in four 40-50 minute sessions in a workshop with a 4-week follow-up. The Chi-square test, Fisher's exact test, paired t-test, independent t-test, and regression analysis comprised the tools used to analyze the data. FINDINGS: The mean performance scores of nurses before the education program in the intervention and control groups were 42.8 (±18.5) and 48.7 (±15.7), respectively. These scores improved to 68.6 (±31.4) and 48.6 (±15.4) four weeks after the intervention (p < 0.001). CONCLUSION: The performance of nurses in providing oral care for mechanically ventilated children improved after the intervention. It is recommended to implement this program for all nurses, regardless of their ward or specialty, based on the clinical practice guidelines. The periodic refreshing in-service training program should be provided to nurses in PICU in order to enhance their performance in providing oral care.

Examining the effect of the computer-based educational package on quality of life and severity of hypogonadism symptoms in males.

OBJECTIVE: The objective of this study was to determine the effect of the computer-based educational package on men's QoL and the severity of their hypogonadism symptoms. METHODS: A quasi-experimental study was conducted on 80 male employees. The data collection tool included the 'Aging Male Symptoms' (AMS) and 'Short Form-36' (SF36) questionnaires. Four sessions were held for the intervention group over a period of 4 weeks. Two months after training, QoL and the severity of hypogonadism symptoms were measured in both the intervention and control groups. The data were analyzed with SPSS 22 software and statistical tests, such as χ2, independent t-test, Fisher's exact test, and paired t-tests. RESULTS: Significant statistical changes were observed in the intervention group before and 2 months after the training in the QoL score in the overall dimensions of physical-psychological health and all its domains except for three domains of emotional role, social function, and pain. Furthermore, the paired t-tests showed significant differences between 2 months before and after the training in all the domains and the overall hypogonadism score in the intervention group. CONCLUSIONS: Based on our findings, the computer-based educational package has a positive effect on QoL and reduction of hypogonadism symptoms.

Comparison the effects of topical application of olive and calendula ointments on Children's diaper dermatitis: A triple-blind randomized clinical trial.

This study compares the effective of of topical application of olive and calendula ointments on childrens' diaper dermatitis (DD). This triple-blind clinical trial was conducted on 73 healthy children under the age of 2 years with non-severe and not infected DD, referred to a pediatric healthcare center in Tabriz, Iran. The children were assigned to 1.5% olive ointment (n = 37) and 1.5% calendula ointment (n = 39) using a random block method with the ratio of 2:2. The severity of DD in both groups was measured and compared on a six-point scale on days 0 (before the intervention) and 3, 5, and 7 after interventions. The findings releaved there was not significant stastistical difference between the olive oil and calendula groups in terms of severity of DD in the third, fifth and seventh days. No adverse effect was reported from either of the medications in this study. The external validity and consequently the ability to generalize the findings may be diminished as this study was conducted at a single site. Owing to olive ointment and calendula ointment providing the same results in the healing of DD, olive ointment can be used as an alternative case to DD.

The Effect of Increasing Blood Flow Rate on Severity of Uremic Pruritus in Hemodialysis Patients: A Single Clinical Trial.

BACKGROUND: Although the prevalence of uremic pruritus has decreased compared to the past, the problem still remains as a matter of health and a major challenge of research in medical field, and has no effective treatment at present. This study aimed to investigate the effect of increasing blood flow rate on severity of uremic pruritus in hemodialysis patients in Iran. METHODS: This clinical trial was performed on 60 hemodialysis patients that referred to hospitals affiliated to Tehran University of Medical Sciences and these patients were selected through the convenience method and were treated for four weeks. They were divided into two groups of experimental and control as random allocation block, and studied for 4 weeks. Information on pruritus severity was collected using a researcher-made questionnaire in three steps of before intervention and two and four weeks after start of intervention. The rate of blood flow was increased in the first two weeks and the second two weeks by 25 and 50 rounds per minute (rpm) compared to the mean rate of blood flow of hemodialysis device in the last two sessions before intervention. Data were analyzed using the tests Mann-Whitney, Fisher, and t-test. RESULTS: Analysis of data from 50 persons in both groups who completed the study revealed a significant difference between the groups in the severity of pruritus between the two sessions of hemodialysis (pruritus at home) at the end of the first two weeks of the intervention (<0.05) and the number of cases of pruritus (<0.05) at the end of the study. CONCLUSIONS: Increasing blood flow for hemodialysis machine can induce significant statistical and clinical reduction in the severity and the frequency of pruritus in hemodialysis patients and can be help to be improve the quality of life of these persons by increased the blood flow rate.

Evening primrose oil and labour, is it effective? A randomised clinical trial.

The purpose of the present study was to evaluate the effects of evening primrose oil (EvPO) on the duration of pregnancy and labour. The study was performed as a triple blind placebo controlled randomised clinical trial on nulliparous low-risk women with a certain gestational age of 40 weeks of pregnancy and a Bishop score of less than 4. In the case group (EvPO group), EvPO capsules were administered, 1000 mg, twice daily, for 7 days, and in the control group, placebo was administered similarly. The women of the two groups were followed up to delivery. In total, 80 women finished the study (40 in each group). The women of the two groups did not have significant differences according to age, BMI, Bishop Score at the beginning of the study, gestational age at entering the study, employment status and education level, the number of capsules used and duration of using medications. There was no significant difference between the two groups according to gestational age at delivery, need for induction or augmentation of labour, duration of different stages of labour, neonatal weight and Apgar scores, and the indications for hospital admission. Impact statement What is already known on this subject? Evening primrose oil has been used for the treatment of systemic disorders, which are accompanied with chronic inflammation such as atopic dermatitis, rheumatoid arthritis and psoriasis. Also, it has been proposed for some women's health conditions including breast pain (mastalgia), symptoms of premenstrual syndrome and menopausal symptoms, cervical ripening and induction or augmentation of labour. What do the results of this study add? Evening primrose oil does not have any impact on Bishop Score and the duration of different stages of labour. What are the implications of these findings for clinical practice and/or further research? According to the present study and the other performed studies, there is not enough evidence confirming effectiveness of Evening primrose oil for cervical ripening and duration of labour. It is suggested that pending further data its usage should be limited to experimental RCTs and its use in clinical practice should be prevented. Also, different routes of administration and different dosages should be investigated.

Comparison of the Effects of Benson Muscle Relaxation and Nature Sounds on the Fatigue in Patients With Heart Failure: A Randomized Controlled Clinical Trial.

This study was conducted with the aim of comparing the effects of Benson muscle relaxation and nature sounds on fatigue in patients with heart failure. Fatigue and exercise intolerance as prevalent symptoms experienced by patients with heart failure can cause the loss of independence in the activities of daily living. It can also damage self-care and increase dependence to others, which subsequently can reduce the quality of life. This randomized controlled clinical trial was conducted in an urban area of Iran in 2016. Samples were consisted of 105 hospitalized patients with heart failure chosen using a convenience sampling method. They were assigned to relaxation, nature sounds, and control groups using a randomized block design. In addition to routine care, the Benson muscle relaxation and nature sounds groups received interventions in mornings and evenings twice a day for 20 minutes within 3 consecutive days. A 9-item questionnaire was used to collect data regarding fatigue before and after the interventions. Relaxation and nature sounds reduced fatigue in patients with heart failure in comparison to the control group. However, no statistically significant difference was observed between the interventions. Benson muscle relaxation and nature sounds are alternative methods for the reduction of fatigue in patients with heart failure. They are inexpensive and easy to be administered and upon patients' preferences can be used by nurses along with routine nursing interventions.

From Visiting a Physician to Expecting Antibiotics: Korean Perspectives and Practices toward Respiratory Tract Infections.

Antibiotic resistance is steadily rising worldwide. Respiratory tract infections (RTIs) are common indications, mostly imprudent, for antibiotic prescriptions in outpatient setting. In Korea, antibiotic prescription rate for RTIs is still high. As physician visit and antibiotic prescribing are influenced by patient's perceptions and beliefs, we aimed to explore the general public's perspectives and practices toward RTIs and to develop the 'RTI clinical iceberg.' A cross-sectional survey was conducted in Wonju Severance Christian Hospital (WSCH) among 550 adults attending outpatient departments during January 2016. Differences in distributions between groups were examined using two-tailed Pearson χ² test. Using the Andersen's behavioral model as a conceptual framework, we constructed logistic regression models to assess factors associated with physician visit. Of 547 participants with complete questionnaires, 62.9% reported having experienced an RTI in the previous six months; 59.3% visited a physician for the illness, most commonly because the symptoms were severe or prolonged, and approximately 16% of them expected an antibiotic prescription from the visit. Perceptions of symptoms severity, the need factor, most strongly influenced physician visit. Predisposing and enabling factors such as inappropriate expectations for antibiotic for a sore throat or having national health insurance also influenced physician visit. Almost all participants who reported asking for an antibiotic were prescribed one, with a 37.1% non-adherence rate. Conclusively, public education on self-care for RTI symptoms that addresses their main concerns may reduce physician visits. Improving physician-patient relationship and informing patients about the lack of antibiotic benefit for most RTIs may also reduce antibiotic prescriptions.

Factor Structure and Construct Validity of Children Participation Assessment Scale in Activities Outside of School-Parent Version (CPAS-P).

The aim of this study was assess the factor structure, reliability and construct validity of the Children Participation Assessment Scale in Activities Outside of School-Parent Version (CPAS-P). The participants of this study were 700 parents of children aged 6-12 years. For data analysis, the confirmatory factor analysis, internal consistency, and test-retest reliability were conducted. Convergent validity was calculated by correlation with the Vineland Adaptive Behaviour Scale. The results indicated the CPAS-P has good internal reliability. Overall, Cronbach's alpha for the participation measures ranged between 0.87 and 0.91, indicating good homogeneity, and Spearman correlations for convergent validity was acceptable. The temporal stability of the CPAS-P was supported with Intra-Class Correlations ranging from 0.79 to 0.94. Therefore, the CPAS-P, which evaluates all eight areas of occupation (i.e., activities of daily living, instrumental activities of daily living, play, leisure, social participation, education, work, and sleep/rest) has demonstrated good psychometric properties; and can be used as a reliable and valid measure to assess children's participation at the age of 6-12 years.

Effect of Tribulus terrestris, ginger, saffron, and Cinnamomum on menopausal symptoms: a randomised, placebo-controlled clinical trial.

Menopausal symptoms experienced by women vary widely, and while many women transition through menopause with manageable symptoms, others experience severe symptoms, which may impair their quality of life. The purpose of this study was to determine the effect of Tribulus terrestris, ginger, saffron, and Cinnamomum on menopausal symptoms. A randomised, triple-blind, controlled trial design was used for this study. The participants were 80 postmenopausal women aged 50-60 years. A demographic data form and the Menopause Rating Scale were used to collect data. The women were randomly divided into two groups, each of which received either an Aphrodit capsule or a placebo twice a day for four weeks. The two bottles looked exactly the same, so that the investigator and the participants were not aware of the contents of the bottles. Each Aphrodit capsule contained 40 mg of Tribulus terrestris, 12.27 mg of Zingiber officinale, 3 mg of Crocus sativus extract, and 11 mg of Cinnamomum zeylanicum, while the placebo capsules contained 50 mg of starch. Descriptive and inferential statistics were used to analyse the data. A statistically significant change was reported in the menopausal symptoms of the intervention group compared with the placebo group. The results of the study demonstrate that the Aphrodit capsule was effective in reducing menopausal symptoms.

Oculomotor rehabilitation in children with dyslexia.

Background: Dyslexia is the most common learning disorder. Visual and oculomotor deficits in dyslexic children have been reported. The purpose of this study was to measure oculomotor parameters and analyze the effect of oculomotor rehabilitation strategies on dyslexia. Methods: Binocular eye movements were recorded by oculomotor subtype of videonystagmography (VNG) testing on 30 children with dyslexia and 20 typical reader children (aged 8-12) in both genders. Dyslexic children were diagnosed with DSM-V scale by experts in reading disorder centers. We studied those children with developmental dyslexia, who had deficits in eye movements recording. Dyslexic children were divided into 2 groups of case and control. Oculomotor rehabilitation (including fixation, saccade, and tracking training) was performed in case group for 1 hour, twice weekly for 8 weeks. Before the intervention, results of oculomotor tests were compared between 3 groups (healthy, case, and control). Then, to analyze the effect of the intervention, results of oculomotor tests were compared between case and control groups in pre- and post- intervention stage. Data were analyzed by independent and paired samples t tests, ANOVA, and repeated measures tests in SPSS v. 21. Results: There were significant differences in oculomotor characteristics of dyslexic children in comparison with those reported in typical children. Oculomotor rehabilitation intervention had a positive effect on improvement of oculomotor responses and eye movements in dyslexic children. Moreover, there was no statistically significant difference between dyslexic children and non-dyslexic children in oculomotor skills after the training. Conclusion: Our results showed the positive effects of oculomotor rehabilitation on eye movements. Primary oculomotor assessment in dyslexic children and early use of oculomotor rehabilitation combined with other treatments are highly recommended.

Assessment of nutritional status in patients with Parkinson's disease and its relationship with severity of the disease.

Background: Malnutrition, loss of body weight, muscle and fat mass wasting are common in patients with Parkinson's disease, and are associated with disability, longer length of hospital stay, impaired immune system and increased risk of mortality. The aim of this study was to assess the nutritional status in patients with Parkinson's disease and its relation to the severity of the disease. Methods: This cross- sectional study was conducted on 130 patients with Parkinson's disease, with a mean (SD) age of 59.1 (12.9) years in disease stages of 1 to 4. In this study, the Mini Nutritional Assessment (MNA) questionnaire was used along with anthropometric measurements (Body Mass Index (BMI), Mid-arm circumference (MAC), Calf Circumference (CC)) to evaluate the nutritional status, and they were applied by a trained nutritionist. Hoehn and Yahr Scale were used to determine the severity of the disease. One-way ANOVA test was used to assess the relationship between anthropometric indices, nutritional status and severity of disease. Assessment of the relationship between age, duration of disease and nutritional status was categorized according to MNA score, and was performed, using one-way ANOVA. Chi - Square test was utilized to assess the relationship between education level and nutritional status. SPSS Version 18 was used for data analysis. Results: In this study, 30% (n=39) of the participants were diagnosed with normal nutritional status, 58.5% (n=76) were at risk of malnutrition and 11.5% (n=15) were malnourished according to MNA. Reduction of weight, and muscle mass wasting was observed in different disease stages. Muscle mass wasting and worsening nutritional status, based on MNA score, showed a significant increase as the disease progressed, MAC (p=0.009), MNA score (p<0.001). After assessing the relationship between education level, age, duration of disease with nutritional status, the results revealed a significant relationship between age (p=0.008), education level (p<0.001) with nutritional status according to MNA score. Conclusion: Reduction of BMI, depletion of muscle mass, and worsening of nutritional status according to MNA, was observed in many patients along with an increase in the severity of the disease. Assessing nutritional status in those with Parkinson's disease to provide information to identify necessary nutritional intervention is highly recommended.

Hearing aid or tinnitus masker: which one is the best treatment for blast-induced tinnitus? The results of a long-term study on 974 patients.

The aim of this longitudinal study was to explore whether a hearing aid or noise generator would be an effective audiological treatment for blast-induced chronic tinnitus. The amount of satisfaction from different hearing devices (hearing aid, noise generator, or both) during different time periods (1, 6, 12 and 24 months after fitting) was assessed. The 974 subjects enrolled in this study were Iran-Iraq war veterans, suffering from tinnitus for at least 2 years. About 84% of the subjects preferred just a hearing aid. Only 2.7% chose the noise generator, and the others preferred to use both devices. There were no significant differences between the hearing thresholds of the 3 groups. The satisfaction score for the hearing aid and combined devices increased by time but decreased for the noise generator. There was no correlation between the satisfaction score and parameters such as hearing thresholds, audiogram configuration and tinnitus pitch. We concluded that, compared with a noise generator, the most long-lasting treatment for blast-induced tinnitus is a hearing aid. The possible cause for such a performance is probably the recovery of the auditory function and neuroplasticity through the hearing aid.

Does henna impact pulse oximetry results?

OBJECTIVE: To evaluate the effects of henna on the results of pulse oximetry in healthy women. METHODS: 100 young women (20-60 years of age) were recruited. The Iranian original red henna was used to colour the index finger of THE non-dominant hand; the middle finger of the same hand was the control. Blood oxygen saturation was simultaneously measured by two calibrated pulse oximeters. RESULT: Henna did not affect pulse oximetry measurement of oxygen saturation. There was no statistically significant difference between the control and the henna dyed fingers. CONCLUSIONS: Henna is not likely to change the accuracy of oxygen saturation measured by pulse oximeter. CLINICAL TRIAL REGISTRATION: 20120906159N20.
