ABSTRACT
Premenstrual syndrome [PMS] is a set of physical, mental and behavioral symptoms with different severity that cause disorders in individual and social relationships. This syndrome occurs during luteal phase of menstrual cycle with complicated reasons. It is one of the most common disorders of childbearing ages. Because of unclear and complicated causes of this syndrome, different treatment methods have been presented. Reflexology is a non-drug method of prevention and treatment of premenstrual syndrome. It is an old, mild and non-invasive method, but there is not enough researches about its effect on symptoms of premenstrual syndrome. This research was carried out in order to determine the effect of foot reflexology on symptoms of premenstrual syndrome in students of dormitories of Jahrom University in 2011-12. This study was a single-blind controlled clinical trial of 90 students with premenstrual syndrome who were resident in dormitory of Jahrom University. The students were randomly divided into two groups of foot reflexology and control. Intensity of premenstrual syndrome was recorded by subjects in two cycles: pre - intervention cycle and intervention cycle. The tools of data gathering consisted of data gathering forms of temporary diagnosis of PMS, and Beck depression test. Descriptive and inferential statistics were used in order to analyze data. There was no statistically significant difference between research variables such as age and menarche age, and the severity of the symptoms before intervention. The average reduction of general severity of PMS symptoms was 23.39% in foot reflexology group while it was -9.68% in the control group [p<0.0001]. There was signification difference between the average of physical and mental symptoms in reflexology group compared to the control group [p<0.0001]. It seems that, foot reflexology is effective in improvement of physical and metal symptoms of PMS. Therefore, it is possible to achieve a main midwifery aim which is to decrease the intensity of PMS symptoms by teaching this simple technique which doesn't need specialists in order to be done.

Thermal changes in laser assisted root canal therapy with the use of diode laser can predispose tooth structure to the fracture. This study evaluated the changes in flexural strength of dentin blocks after diode laser irradiations [810 nm]. A total of 60 dentinal blocks were prepared from freshly extracted teeth in three different thicknesses [300, 500 and 1000 micro m] and 20 sections in each of these thicknesses were divided randomly to the test and control groups. Samples in the test groups were irradiated at 2W power setting by scanning movement of 2mm/s of diode laser, and the controls were stored in normal saline. The flexural strength of samples was evaluated by UTM [Universal Testing Machine]. Data analysis was done with the SPSS Software 11.5. Samples of 300 micro had the lowest flexural strength [mean: 71/65 mpa] followed by 500 [116.64 mpa] and 1000 micro [217.56 mpa]. Statistical analyses showed that after laser irradiation, the flextural strength in the samples of 300 micro was significantly lower than that in the other groups [500 micro, 1000 micro] [P= 0.017]. Within the limits of this study, diode laser irradiation in laser assisted root canal therapy has no significant effect on flexural strength of root dentinal walls with the thickness of more than 500 micro. Although in areas with critical dentinal width [

Electric pulp testing is used for diagnosis of the pulp status. This test is technique sensitive and hence may elicit positive or negative false response in case of inaccurate use. The optimal site for placement of the probe tip has not been determined. The aim of this study was to evaluate the effect of pulp tester probe placement site on the response of maxillary teeth. A total of 378 teeth [126 central incisors, 126 lateral incisors and 126 canines] in 67 voluntary 20-35 year-old patients were selected. Three sites on each tooth [incisal edge, labial and lingual surfaces] were tested with an electrical pulp tester and responses were recorded. Data were analyzed by Repeated Measure ANOVA test. The central incisor teeth showed significantly lower sensation threshold than lateral incisor and canine teeth [P<0.001]. The incisal edge of tooth were significantly more sensitive compared to labial and lingual surfaces [P=0.008]. This study showed that the optimum site for placement of pulp tester probe was incisal edge.
ABSTRACT
Postoperative nausea is a common problem after general anesthesia, especially in ambulatory surgery. In ocular surgeries including strabismus surgery, intraocular pressure increase may lead to eye damage. Drug therapy has various side effects. The purpose of this study was to evaluate acupressure on nausea in patients undergoing strabismus surgery. In this double-blinded clinical trial, 60 patients undergoing strabismus surgery were allocated into intervention and control groups. In the intervention group, a sea-band was placed on the P6 point of patients' wrists 30 minutes before induction of anesthesia. In the control group, the sea-band was placed in the opposite position of the patients' wrists. Data were collected during six hours after surgery in the recovery room. Data were analyzed using Chi square, t-test, and Mann-Whitney tests. There were no differences in demographic and surgical characteristics between the two groups at baseline. The intensity of nausea in the recovery room [P=0.002] and six hours after surgery [P<0.001] were significantly less in the intervention group than the control group. Based on the findings of this study, acupressure decreases post operative nausea. Acupressure is a simple, noninvasive and cost-effective intervention which can be applied by nurses to prevent post operative nausea
ABSTRACT
Dysmenorrhea is one of the most common disorders of women in reproductive age. In addition to physical and psychological disturbances, it may cause socioeconomic problems. The acupressure is a suggested treatments for dysmenorrhea. This study was conducted to identify and compare the effects of acupressure in Saninjo and DiJi points on pain severity of primary dysmenorrhea and systematic symptoms associated with it. This study was a cross-over clinical trial. 50 girls aged between 18 and 30 years old referred to an urban health center in Sar-e-Pol-e-Zahab city were selected. Subjects randomly allocated into two equal groups [A and B] and were assessed over three consecutive menstrual cycles. A questionnaire was used for data collection. Validity and reliability determined by content validity and test retest methods respectively. Pain severity was assessed using McGill pain ruler. At the end, data from 42 women were used for analysis with SPSS package. The severity of primary dysmenorrhea was 6.65 +/- 1.05 in SP6 and 6.84 +/- 1.9 in SP8 before acupressure and significantly decreased to 2.89 +/- 1.36 and 2.03 +/- 0.94 respectively after acupressure [P<0.001]. We can conclude that dysmenorrhea pain decreased after acupressure and SP6 and SP8 points can be used as an urgent remedy to alleviate primary dysmenorrhea
