The presence of a blind child in the family puts a lot of pressure on the caregivers, especially the mother. Therefore, the mother’s mental and emotional condition is affected and disturbs her ability to balance time. By knowing the pattern of time use in mothers of blind children, it is possible to help improve the health and quality of life of these mothers. This study aims to evaluate the time use in mothers of children with blindness compared to the mothers of healthy children.

This is a descriptive and cross-sectional study. Ninety mothers of blind and healthy children aged 6-14 years participated in this study. Mothers were selected from among those whose children were in exceptional schools of Shahid Mohebi, Narjes, and Khazaeili and normal schools in West of Tehran, Iran using a convenience sampling method. Mothers’ time use for different activities was evaluated by the Persian version of the Mothers’ time Use questionnaire. The collected data were analyzed in SPSS software versio 21 using independent t-test and Mann-Whitney U test.

Mothers of children with blindness spent more time on household chores and childcare and less time on sleeping/resting compared to the mothers of healthy children (50.0≥P).

The presence of a blind child in the family affects the ability of mothers in balancing the time and the quality of the time spent by them on daily activities. Therefore, there is a need to pay attention to balance of time as a variable of health and quality of life.

A proper hand function is essential for performing activities of daily living. Hand injuries can significantly affect participation in these activities. Therefore, any factors that interferes with the treatment of hand injuries and postoperative recovery such as smoking should be controlled. Smoking cigarettes use is a public health problem worldwide. The present study aims to investigate the relationship between smoking cigarettes and hand function after tendon repair in men.

This cross-sectional study was conducted on 40 men (20 smokers and 20 non-smokers) who had undergone at least 10 sessions of physiotherapy and 10 sessions of occupational therapy one and a half months after tendon surgery. In order to collect the information, a demographical form and the shortened disabilities of the arm, shoulder and hand questionnaire (QuickDASH) were used. The collected data were analyzed in SPSS software, version 22.

There was a significant difference in hand function after tendon repair between smokers and non-smokers (P=0.006). There was no significant relationship between the number of cigarette consumed per day and hand function (P=0.3)

It seems that there is a significant relationship between smoking and hand function after tendon repair, but there is no significant relationship between the number of cigarettes smoked per day and hand function. Individual counseling to smokers with hand injuries and expressing the possible negative effects of smoking on their hand function can increase the effectiveness of rehabilitation in them.

Background and Aims :

Urinary incontinence (UI) has been known as one of the clinical manifestations of pelvic floor muscle (PFM) instability; however, limited research has been published on PFM function in patients with different types of UI. This study aimed to compare the PFM function of the continent women and women with Stress urinary incontinence (SUI) and overactive bladder (OAB).

Methods :

This cross-sectional comparative study was performed on 30 women, 10 continents, 10 SUI, and 10 OAB, with a mean age of 42.67±4.77 years. PFM function was assessed using manual muscle testing, a perimeter, and surface electromyography. Data analysis was performed using SPSS software and the level of significance was considered as P≥0. 05.

Results :

There was no significant difference in the PFM function, strength, and electromyographic activity between SUI and OAB patients.  However, it decreased in both groups compared to the healthy group (P=0.001). Also, a strong correlation was found between clinical examination, a perimeter, and electromyography (r=0.82, P=0.0001).

Conclusion:

 This study revealed that the PFM function was impaired in both groups of women with SUI and OAB. Also, both manual examination and the perimeter can be used as clinical methods in evaluating PFM function.

 Family-centered services are collections for children with special needs and their families. These services consider families as expert about childrenchr('39')s needs. The essence of this approach is involvement of family in decision making, cooperation, and mutual communication (family and therapist), mutual respect, acceptance of family choice, family support, flexibility of service, and effort to empower families. These services have become a basic foundation of many early intervention programs and are especially useful in rehabilitation services. MPOC-20 is one of the questionnaires used to evaluate these services. This questionnaire consists 20 questions divided into 5 areas, the areas include the following: 1) enabling and partnership, 2) providing general information, 3) providing specific information about the child, 4) coordinated and comprehensive care for child and family, and 5) respectful and supportive care. This tool has been translated and validated in several countries and specifically in several diseases. In this study, the validity and reliability of this tool have been investigated.

 This study was a descriptive-analytical and in order to measure the validity and reliability of MPOC-20, content validity, correlation coefficient and reliability of the test-retest were done. To determine the content validity, 14 occupational therapists were asked and the result was calculated by measuring the content validity index and content validity Ratio. Then, an MPOC-20 questionnaire along with a form of demographic information and a consent form were given to 340 parents of children (children under 18 years and with different diagnosis) in clinics of Tehran. The articipants consisted of 142 girls patients (42%) and 198 boys (58%) randomly selected from public and private rehabilitation centers in different regions of Tehran. A large percentage of respondents were mothers (314 people were 92.4%). After 2 weeks, the questionnaire was again distributed among 30 of them, and the ICC coefficients were calculated. In order to determine the internal consistency, Cronbachchr('39')s alpha was calculated.

 The content validity index and content validity Ratio for all items were acceptable and no items were deleted. Cronbachchr('39')s alpha was 0.81 which indicates a high correlation between items in the questionnaire. The highest Cronbachchr('39')s alpha coefficient is related to the field of providing general information about the child (α=0.77). Also, in this section, the p-value was significant for all fields at the level of 0.001. In the reliability of the test-retest, the scores of the Intra-class correlation coefficient of all domains were higher than 0/6 which indicates a medium to good reliability of the questionnaire. Reliability in the field of supportive care had a high coefficient and good reliability. In other areas, the reliability was moderate.

 Considering the importance of evaluation in improvement of family-centered services provision, a strong tool is needed and MPOC-20 is well known in this regard. The results of this study showed that the Persian version of "MPOC-20" questionnaire has a good validity and reliability in children under the age of 18, and it can be used to assess family-centered services in both research studies and as clinical tool.

Sensory problems can affect the functioning of individuals in a variety of daily activities in different aspects. One of these aspects of daily activity is the quality and quantity of sleep. Sensory processing is perhaps the most basic psychological element that determines how individuals perceive and respond to environmental stimuli. Given this, the present study aimed to investigate the effect of sensory processing disorder on students' sleep quality.

The current descriptive cross-sectional study was conducted on 184 students of the School of Rehabilitation at Shahid Beheshti and Iran Universities of Medical Sciences. Two Pittsburgh Sleep Quality Questionnaires and Adolescent-Adult Sensory profile were used for data collection. Data were analyzed using SPSS 18.

The results of data analysis showed that 49.1% of the students had undesirable sleep quality and most of the students had sensory processing disorder of sensory seeking type. The results showed a significant relationship between sleep quality and the three variables of low registering, sensory sensitivity, and sensory avoidance (P-values: 0/017, 0/003, 0/02, respectively).

The findings of the present study emphasized that students with poor sleep quality had sensory processing disorder and their sleep quality reduced. Also, there was a significant relationship between low registering, sensory sensitivity, and sensory avoidance with sleep quality. Therefore, it seems necessary to support students in considering proper sensory diet and taking measures to resolve their sensory problems and thus improve their sleep patterns.

Routine verbal communication almost never occurs in quiet. Speech perception disorder in noise is one of the most common complaints of people of all ages. In our living environment, there are different types of background noise that have different masking effects. In general, verbal noises have more signal target masking. Babble noise as an interfering factor can lead to speech perception disorders. Speech phonemes are alienated into consonants and vowels across languages. These phonemes are different in terms of production and perceptual mechanism. Persian has 6 vowels /i/, /e/, /a/, /â/, /o/, and /u/. Vowels are the nucleus of the syllables and words, vowel errors can lead to disorders in speech perception process. Now the question arises as to whether the ability of vowel recognition in the presence of babble noise is influenced by age, signal to noise ratio, gender, and educational level? Also, if the above factors affect the recognition of the Persian vowel, which vowels are more vulnerable to these effects?Therefore, due to the absence of similar studies on the effect of the aforementioned factors on the recognition of Persian vowels, the present study examined the effect of age, signal to noise ratio, sex, and educational level on the recognition of Persian vowel in the fourth and fifth decades of life. This observational and cross sectional study was performed on 60 adults with normal hearing in the age range of 30-49 years with mean and standard deviation (SD) of 38.88±6.23 years old (thirty people aged 30 to 39 years old with average age and standard deviation (SD) of 33.40±2.35 years and thirty aged 40 to 49 years with average age and standard deviation (SD) of 44.73±2.33 years) from available samples. After the auditory and speech evaluation, the recognition of Persian vowels were examined in consonant-vowel-consonant syllable in the presence of babble noise in signal-to-noise ratios of 0, -5 and -10, along with  the randomized presentation of stimuli to the right ear. The purpose of the random presentation of syllables in the present study was to avoid memorizing words.Comparison the recognition score of six Persian vowels showed significant differences in three signal-to-noise ratios (p = 0.001). Also, comparison the vowels recognition scores were significant in two age ranges of 30-39 and 40-49 years old in three signal-to-noise ratios (p = 0.001). However, not found significant differences between the sexes (P= 0.991) and different educational levels (P= 0.282). Also, in three signal to noise ratios of 0, -5 and -10, the recognition scores of the front vowels were better than the back vowels. In signal-to-noise ratios of 0 and -5, the highest mean of recognition score was associated with / a / vowel and in the signal-to-noise ratio of -10 with / i / was present. Also, there was the lowest mean of recognition score in signal-to-noise ratios 0, -5 and -10 with / u / vowel. The present study showed that the average recognition of Persian vowels is affected by age, signal-to-noise ratio, and type of vowel. As the age increases and the signal-to-noise ratio decreases, the average recognition score of the vowels decreases significantly in the presence of babble noise

Eyes are very sensitive to Sulfur Mustard gas (SM) because they have wet surfaces. Considering the late complications of eye due to mustard gas exposure in warfare patients, the present study was conducted to evaluate the late complications of the eye.

In the current descriptive study, we evaluated 300 male patients aged between 40-75 years old whose mustard gas injury period was about 27-32 years before. A complete eye examination by an ophthalmologist was done. The complications were divided in 4 grades: normal, mild, moderate, and severe. The results were reported as x2 and relative frequencies.

Out of 300 warfare patients, 37.5% were aged 46-50 years old, 79% were injured with mustard gas once, 13.4% twice, 6.6% three times, and 1% more than 3 times, 42% had hospitalization, and 77.6% used drugs. The most common symptoms were itching (42.3%), burning (38.3%), and dryness (37%) and the most prevalent complication of the lid was MGD (39.4%). Also, the most prevalent complication of Conjunctiva was vascular anomalies (46.6%), the most common complication of limbus was ischemia (12%), and the most common complication of cornea was epithelial defect (13.4%). Among the prevalent ocular surgeries were punctual occlusion (19.4%), penetrating keratoplasty (PK) (0.33%), tarsoraphy (0.66%), conj.flap (1%), amniotic membrane transplantation (0%), stem cell graft (2.66%), and lamellar keratoplasty (LK) (0.66%), in the order of frequency. The degrees of complications were 53.34% for normal, 33.33% for mild, 9.33% for moderate, and 4% for severe cases.

Conjunctival vascular abnormalities and epithelial defect were the most significant signs among the sulfur mustard chemical war victims. Having reached the mentioned conclusions, it can be stated that mild complications were more than moderate and severe ones.

Ocular biometry parameters are important factors which have valuable roles in diagnostic and therapeutic procedures in ophthalmology. The aim of the present study was to determine the relationships between height, weight, and Body Mass Index (BMI) and Ocular biometric parameters.

A total of 123 participants underwent ocular examination in Noordidegan eye clinic. Inclusion criteria were spherical refractive error ranging between plano to ±2.00 diopter, astigmatism between plano to -2.00 diopter, and best corrected visual acuity of 20/20. Also, exclusion criteria were diabetes, blood hypertension, thyroid problems, keratoconus, corneal scars, pterygium, cataracts, glaucoma, and any ocular surgery history. Ocular biometric parameters were analyzed using Lenstar, and height and weight were measured according to the standard protocol.

Ocular biometric data were collected from participants with an average age of 36.10±8.41 including 61 women (49.6%) and 62 men (50.4%). The average value of height, weight, and BMI were 170.40±9.81 cm, 79.84±18.91 kg, and 27.54±6.18 kg/m2, respectively. Also, the averages of eye axial length, central corneal thickness, anterior chamber depth, crystalline lens thickness, and corneal power were 23.59±0.82 mm, 538.60±36.84 µm, 3.57±0.32 mm, 3.79±0.35 mm, and 43.67±1.42 D, respectively. It was observed that height correlated positively with axial length and anterior chamber depth (p

Our results indicated that eye axial length and anterior chamber depth increase with increase in height and weight and corneal power decrease with increase in height. Also, a direct association was observed between BMI and crystalline lens thickness.

Assessment of auditory processing in children is performed via special tests with confirmed sensitivity. For any adapted or developed test, there should be evidences to demonstrate acceptable test-retest reliability. Recently, two dichotic listening and two recognition of speech-in-noise tests of auditory processing have been developed in Persian language. The present study aimed to assess test-retest reliability of these tests in normal children.

The present observational and analytic study was performed on 40 children, aged 6-12 years old, selected from two elementary schools in Tehran. Inclusion criteria were right-handedness, normal peripheral hearing sensitivity (

The mean score of FARDIN and PARWIN did not show a significant difference between tests and retest sessions. Dichotic listening tests scores showed a significant improvement in retest session. Intra-class correlations for tests of recognition of speech-in-noise and dichotic listening tests were 0.6-0.65 and 0.6-0.9, respectively. FARDIN and PPCW showed higher absolute reliability compared with PARWIN and PPCS tests, respectively.

Although children' performance for dichotic tests in retest session was slightly better, it seems that auditory processing tests used in the current study have adequate test-retest reliability in normal children.

Retinitis Pigmentosa (RP) is a group of hereditary retinal degenerative diseases, causing blindness among individuals younger than 60 years, and patients have to continue with visual impairment for their entire lives, which can cause changes on their quality of life. The purpose of the present study was to determine the vision-related quality of life using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) in patients with RP, and to examine the relationship between quality of life and visual acuity.

The present cross-sectional study included 35 patients with RP (18 male, 17 female) with the mean age of 37.57±11.42 and 35 normal participants for control (18 male, 17 female) with the mean age of 36.11±9.32. Best Corrected Visual Acuity (BCVA) sores were measured in distance and near. Participants answered the Persian version of the NEI VFQ-25. The difference between RP and normal group and the correlation between quality of life and visual acuity were determined.

The mean NEI VFQ-25 scores were 47.59±18.72 in RP patients and 92.29±5.48 in normal controls. This difference was highly significant (P

Retinitis pigmentosa and decreased visual acuity have a great impact on the quality of life.
