Abstract: Cell phone or usually called as mobile phone is one of the communication device that nowadays being developed. Global debate and controversy about the health effects of mobile phone keep continuing. There are some concerns about radio frequency energy (radio waves) emitted from the phone that may cause health problems, especially for auditory function. The observational analytic research with cross-sectional design has been carried out in November-December 2012. A number of 40 people have been chosen based on some inclusion criterias. The characteristics of the subjects were obtained by using a questionnaire and electromagnetic radiation examination of cell phones using electromagnetic field tester. Some auditory function tests were done using an audiometric. The data has been analyzed using Statistical Program Product and Service Solution (SPSS) with bivariate test (Pearson correlation). Audiometric tests showed there were eight students (20%) with a mild hearing loss in the left ear and the rest 32 students (80%) did not have a hearing loss. Meanwhile, three students (7.5%) have a mild hearing loss in the right ear and the rest 37 students (92.5%) did not have a hearing loss. Based on these results, it could be concluded that there was no significant relationship between electromagnetic wave radiation of cell phones and hearing function.Keywords: cell phone radiation of electromagnetic waves, the function of hearingAbstrak: Telepon selular atau biasa juga disebut handphone adalah salah satu alat komunikasi yang sedang berkembang saat ini.

The Impact

Background: The main purpose of study was to assess the impact of using mobile phones among young Ukrainians (age 17-25) on auditory system. We conducted a study using anonymous questionnaires and with using a method of objective audiometry (otoacoustic emission). Finally, we compared our results with results of studies which were conducted in Sweden and Finland. Those studies were first among all the others with assessment of association between amount of mobile phone use and frequency of headache, tinnitus or hearing loss at 4-year follow-up. Methods: The participants were chosen among volunteers (n=251). All of them received anonymous questionnaires. We made stratified sample by age, sex, type of phone used, duration of phone calls, using of headphones during calls, symptoms appearing after using cell phone (headache, tinnitus, hearing loss). Results: The age of respondents was 17-25 years (32,3% - 22 years, 13,1% - 19 years, 12,4% - 20 years, 10,8% - 23 years., 8,4% - 21 years., 8% - 18 years, 7,6% - 17 years, 2,8% - 24р., 2,8% - 25 years). Due to this data the median age of participants was 22 years. Sex: female – 74.3%, male – 25.7%. Most of participants were using mobile phones (99.2%). 51.8% of respondents were always using headphones during phone calls, 8.8% - never used headphones during phone calls, 39,4% - were rarely using headphones during phone calls.  We assess the association between mobile phone use and appearing symptoms after phone calls. 3.6% of respondents reported a headache after phone calls, 96.4% were free of this symptom after phone calls. 58.2% reported headache at least once a week, 41.8% - were free of this symptom. 42.2% of respondents reported tinnitus: 1.6% reported tinnitus every day, 4.8% once in 2-3 days, 35.9% reported this symptom rarely (less than once a week). 57.8% of respondents were free of tinnitus. 21.5% of respondents reported hearing loss, 78.5% were free of hearing loss. Most of respondents associate headache with fatigue, sleep deprivation, stress, weather change, sleep disorders, arterial hypertension, hunger, frequent phone calls. Respondents who complained of hearing loss were offered to pass objective audiometry (optoacoustic emission).6 respondents took part in this examination. In 85 ears of respondents (71%) who complained of hearing loss it occurs on 8000 Hz. In 95 ears of respondents (79%) who complained of hearing loss it occurs on 5714 Hz. Pearson correlation coefficient between our results and results of Northern Europe studies was 0.935, suggesting a strong linear association.

BACKGROUND: Today, mobile phones are recognised as an inseparable part of our daily lives, facilitating communication between users. Based on the studies, addiction to cell phones can lead to several complications including depression, anxiety, anger, and aggression. AIM: This study aimed to investigate nomophobia (no mobile phone phobia) among medical students of Islamic Azad University, Tehran Branch. METHODS: This descriptive cross-sectional study was conducted on 100 students studying in different majors of medical sciences in Islamic Azad University, Tehran Branch, from 2016 to 2017. Demographic data of all participants were recorded in a data sheet. In the next stage, a questionnaire was designed by the researcher to evaluate the effect of age, gender, education, and the duration of using cell phone variables on discomfort, anxiety, and insecurity due to lack of access to cell phone or other related issues. Raw data were analysed using SPSS statistical software version 21. The significance level was considered P < 0.05. RESULTS: The results of the study showed that participants with lower mean age felt more discomfort, anger, anxiety, and insecurity due to lack of access to mobile phones and other related issues compared to other people. However, no variable was statistically significant (P-value > 0.05). Except anxiety, results showed that longer duration of mobile phone use might lead to a significant decrease in discomfort, anger, and insensibility variables among users (P-value > 0.05). The incidence of nomophobia (with its different aspects) was significantly lower in females (P-value > 0.05). Also, in participants with higher educational status, the nomophobia was recorded to be more frequent (P-Value > 0.05). CONCLUSION: Understanding the pattern of nomophobia occurrence among cell phone users can facilitate our path to prevent its harms including discomfort, anger, anxiety, and feeling of insecurity among users of technology.

Mild Hearing Loss

Abstract Introduction Hearing is important for the proper development of every child, especially for those younger than 5 years of age, because it helps in the development of language and speech. Emotional and social problems, as well as issues with academic performance, can result from hearing loss even of mild degree. Early diagnosis and management can overcome those negative impacts. Objective To determine the prevalence of mild hearing loss in primary-school children and its association with their school performance. Methods A comparative cross-sectional study was conducted at a regular school. The study included the random selection of 120 apparently normal students (aged 6-9 years) who were considered as having normal hearing by their parents. A total of 20 students were excluded from the study due to the presence of wax in their ears. Finally, the study was conducted with 100 students. All participants were subjected to a basic audiological evaluation, and the Screening Instrument for Targeting Educational Risk (SIFTER) questionnaire was given to their teachers to evaluate their school performance. Results From a total of 100 students, we confirmed that 23 (23%) had mild hearing loss, 17 (17%) had bilateral conductive hearing loss, and 6 (6%) had bilateral sensorineural hearing loss. The students who had low attention and communication performance were significantly associated with mild hearing loss. Conclusion The prevalence of mild hearing loss was of 23% (23 cases). This problem had an effect on the communication and attention in school; and it might affect academic performance later in life. A hearing assessment is highly recommended for every child, especially those who have a low rate of academic performance.

Mobile Phone Accidents - Experience Of India Every year nearly 1.4 million people have been killed because of they are wireless customers and their over-bearing cell phones. While in India, an estimated 1.35 lakhs person died due to road accident in 2010, which is approximately 10% of road accident fatalities worldwide and these figures are the highest in the world. But still no research has been carried out to find the number of drivers using cell phone involved in road accident and very limited efforts has been carried out to prevent accident due to cell phone usage. To our knowledge this is the first survey carried out in India to determine the number of drivers involved in an accident due to mobile phone use. With the aim of preventing such accidents, it is proposed to develop a highly efficient automatic system for early detection of incoming and outgoing call, by placing an antenna along with mobile detection unit above the driver seat. This unit is capable of distinguishing whether the cell phone used either by the driver or by the passenger, if the driver uses of cell phone is detected, a safety application named Cellphone Accident Preventer (C.A.P.) which is developed using J2ME will be automatically load on the driver's cell phone which helps in eliminating the risk of accidents from occurring, at the same time ensuring that the user does not miss any emergency call. The research has been extended to show how far the system will help in preventing accidents and to what extent this system will help in reducing the Indian economic loss incurred unnecessarily due to road accident fatalities.

Aims: Mobile/cell phone use has become an important socio-medical means of communication. The reason people use a particular ear to answer phone calls more frequently may be associated with hemispheric dominance/ handedness. We aim to determine association between hemispheric and or auditory dominance in laterality in mobile phone use.    Study Design:  This was a three month prospective cross-sectional study involving all consenting medical and paramedical respondents. Place and Duration of Study: Hospital community in the University of Benin Teaching Hospital (UBTH), Benin City , between 15th March to 15th June 2018. Method: A modification of the Edinburgh handedness inventory (EHI) was the survey tool. Information retrieved included social demographics, hand most commonly used for activities like writing and picking of phone calls and ear used for phone conversation and the reasons. Data was analyzed using SPSS 19.0 Results: Of the 300 questionnaires distributed, 234 (78%) were completed by the respondents. There were 120(51.3%) males and114 (48.7%) females.  Age ranged from 18 - 80years. A total of 201(85.9%) were right handed, 16(6.8%) left handed and 14(6.0%) ambidextrous. One hundred and fifty four (66%) routinely use their right hand to pick phone calls, 50(21.4%) left and 27 (11.5%) use both hands. A total of 141(60%) receive calls with the right ear, 60 (25.6%) with left, and 31(13.2%) had no preference.  Reasons advanced for the use of any particular ear included convenience 173 (73.9%), and better acuity 35(15%). Forty two (17.9%) agreed that the use of cell phone made them aware of their poor hearing in a particular ear. Using Pearson’s two tailed test of significance the probability of a right hander using the right hand to pick a phone call and placing it on the right ear is 0.99 or 99%, Vis a Vis left hander. Conclusion: There appears to be an association between hemispheric dominance and laterality when using the mobile phone.

Objective: To assess the hearing loss among the subjects using excessive mobile phone. Methodology: 50 subjects were entered for this study with age ranging from 20 to 40 years using mobile phone for more than 5 years. 25 subjects who used mobile phone for less than (<) 60 min /day formed one group, while 25 subjects who used cell phone for more than (>) 60 min /day formed the second group. The hearing levels of all the subjects were tested using Pure Tone Audiometry (PTA). Duration of mobile phone usage was assessed by questionnaires. Results: There was a significant increase (p-value .00006) in the hearing thresholds at all frequencies in air conduction and bone conduction in right ear in test group compared with the control group. Similar result was found in the left ear except for bone conduction at frequency 4 and 6 (kilo hertz) kHz. Excessive use of mobile phone caused Sensory neural hearing loss and the prevalence was 84% in group who used mobile phone for > 60 min / day and 20% in group who used for < 60 min / day. Conclusion: Excessive use of mobile phone may cause increase in pure tone threshold associated with the duration of usage. The use for more than 5 years with more than 60 minutes daily can produce harmful effects on human hearing.

Objective.To assess the use of cell phones and email as means of communication between pregnant women and their gynecologists and family physicians.Study Design.A cross-sectional study of pregnant women at routine followup. One hundred and twenty women participated in the study.Results.The mean age was 27.4 ± 3.4 years. One hundred nineteen women owned a cell phone and 114 (95%) had an email address. Seventy-two women (60%) had their gynecologist's cell phone number and 50 women (42%) had their family physician’s cell phone number. More women contacted their gynecologist via cell phone or email during pregnancy compared to their family physician (P=0.005and 0.009, resp.). Most preferred to communicate with their physician via cell phone at predetermined times, but by email at any time during the day (P<0.0001). They would use cell phones for emergencies or unusual problems but preferred email for other matters (P<0.0001).Conclusions.Pregnant women in the Negev region do not have a preference between the use of cell phones or email for medical consultation with their gynecologist or family physician. The provision of the physician’s cell phone numbers or email address together with the provision of guidelines and resources could improve healthcare services.
