Abstract
Background: Cephalometry is one of the important branches of anthropometry that has wide uses in identification, forensic medicine, plastic surgery, orthodontics, archeology and determining the origins of races. This research was investigated to determine the head and face phenotypes among one-day newborn boys in two aborigines of Sistani and Baluchi who were resident in Zahedan.
Materials and Methods: The investigation is based on cross-sectional analytical descriptions of 420 newborn aborigine boys (216 Sistani & 204 Baluchi), who were clinically healthy, in Quds hospital in summer 1381, in Zahedan. In this study cephalic and prosopic indices were determined by classical cephalometric.
Results: The mean and the standard deviations of cephalic index were 83.67±4.80 and 83.64±4.77 and prosopic index 86.79±5.87 and 86.53±6.76 for Sistani and Baluchi subjects respectively. Based on the cephalic index, the dominant head types in sistani group were hyperbrachycephalic (37%) and brachycephalic (37%). In Blachui group, the hyperbrachycephalic (37.3%) and brachycephalic (35.3%) type were the dominant one. Furthermore, according to the prosopic index. The dominant face type among sistanis was euryprosopic type (42.6%). In Baluchi group, the dominant face type was also euryprosopic (39.2%).
Conclusion: This research showed no statistically significant differences in terms of head and face type indices between two aborigines of Zahedan. Based on this cross-sectional study, it seems that there is similarities between the aforementioned groups

Abstract
Background: Psychological debriefing has been widely advocated for routine use following major traumatic events. Cognitive Behavioral Interventions, art supportive therapies, and sport and recreational support activities are other interventions for reducing posttraumatic stress disorder. We assessed the effects of theses methods individually and in combination on reduction posttraumatic stress disorder symptoms in adolescents who had experienced Bam earthquake.
Methods: In a field trial, we evaluated the efficacy of psychological debriefing, group cognitive-behavioral therapy, art and sport supportive interventions in 200 adolescents with PTSD symptoms who survived of Bam earthquake and compare it with a control group. Patients were randomly assigned to one of intervention programs including: group cognitive-behavioral therapy group CBT plus art and sport interventions art and sport interventions without group CBT and control group.
Results: Thirty one individuals were excluded because of migration. A statistically significant reduction in overall PTSD symptoms as well as in avoidance symptoms was observed after group cognitive-behavioral therapy. There was no significant difference in reduction of overall PTSD and avoidance symptoms between the other groups.
Conclusion: Psychological interventions in form of group cognitive behavioral therapy can reduce the symptoms of PTSD symptoms but we couldn't find the art and sport supportive therapy alone or in combination with group CBT to be useful in this regard.

Abstract
Background: Many studies have shown the efficacy of cognitive – behavioral
therapy and psychological debriefing in treatment of post traumatic stress
disorder (PTSD) and a few evidences are available for using these techniques
in large scale disasters. This study aimed to asses the effect of some
psychological interventions in reducing PTSD symptoms after Bam earthquake
in different age groups.
Methods: In a before-after quasi experimental clinical trial, we compared the
efficacy of one session of psychological debriefing and three sessions of group
cognitive-behavioral therapy in bam earthquake PTSD symptoms in different
age groups. We evaluated PTSD symptoms before and immediately and three
months after interventions by CASP scaling system and analyzed data.
Results: one hundred and thirty persons entered in the study and 51 persons
excluded during interventions because of migration. Interventions were
showed to be effective only in short term period. The means of PTSD
symptoms frequency and severity of avoidance symptoms were reduced during
three months period of study which were statistically significant P<0.05.
Interventions showed no efficacy for recall symptoms in long term and hyper
arousal symptoms in short term and long term periods. There was no
statistically significant difference among age groups.
Conclusion: Psychosocial supportive interventions may be effective on some
of the PTSD symptoms but there is no difference in different age groups.

Abstract
Background: Infant formula, depending on the source, contains various fatty acids, which may possess important nutritional and biological value for infants. The presence of some of these fatty acids in infant formula, however, can be harmful and toxic for the infant. In this regard, more attention has been paid to erucic acid since its accumulation in myocardial tissues may cause damage to the heart. Therefore, a limit has been set by the Codex Alimentarius for the presence of erucic acid in infant formula (less than 1% of total fatty acids). The purpose of the present study is to investigate amount of erucic acid present in three infant formulas used predominantly in Iran.
Methods: Gas chromatography (GC) is a valuable method applied for the separation of fatty acids, including erucic acid, from oils and oily food. Three brands of infant formulas, namely Humana, Biomil and Multi, were analyzed by GC using a wall coated open tubular (WCOT) fused silica column and flame ionization detector (FID). Heneicosanoic acid was employed as an internal standard.
Results: The findings showed that Humana and Biomil infant formula samples contained 0.06% and 0.002% erucic acid (from total fatty acids), respectively, while no erucic acid was detected in the Multi infant formula samples.
Conclusion: The amount of erucic acid in the studied infant formulas was far below the Codex limit of 1% total fatty acids.

Abstract
Background: Hearing is one of the most significant senses There fore, any defect can be frightening. The incidence of sever hearing loss following coronary artery bypass surgery has been estimated as one per thousand. This Prospective study carried out to determine hearing effects of coronary artery bypass surgery.
Methods: age, audiometric changes before and after surgery (hearing levels at multiple frequencies, speech reception threshold and speech discrimination score), minimum blood pressure during the operation, and the time on bypass, measured on One hundred consecutive patients who candidate for coronary artery bypass surgery and the results analysed.
Results: One hundred patients completed the tests. Based on hearing changes found on pre- and post-operative tests, the patients were divided into 3 groups: Those with no change (47 patients) according to their audiometric results those with slight changes ≤10 db (43 patients) and those having average deficits of more than 10 db (10 patients). All the patients were male. None of the patients had complete or severe sensorineural hearing loss. The third group had more prolonged pumping duration when compared with the others groups (p=0.002). Furthermore, 90 percent of patients with a sensorineural hearing loss more than 10 db had diabetes mellitus and hyperlipidemia as risk factors.
Conclusion: Sudden sensorineural hearing loss is a sequela in patients who undergoing coronary artery bypass surgery however, it was usually mild and asymptomatic. Pumping time during the operation is a significant factor in occurring of this complication. With proper treatment of underlying diseases and eliminating the risk factors with improvement of our cardiopulmonary pumps we probably can get better hearing results.

Abstract
Background: Rationalize of drug use in societies is one of the main responsibilities of
health policy makers. In our country irrational use of dugs has increased in the recent
years, for example one study in 1998 has shown that average number of medicines per
prescription was 3.6, percentage of prescriptions containing antibiotics was 43% and
percentage of prescriptions containing Injections was 39%. One of the best tools for
evaluation of drug use is the WHO guideline for calculating prescribing indicators. In this
study, we had an assessment about prescribing patterns in South of Tehran, Islamshahr
and Rey Health Centers.
Methods: In order to evaluating prescribing indicators in Tehran University of Medical
Sciences region 35 facilities which had pharmacy were selected according to WHO
gridline and 4190 prescription from these facilities were studied. Indicators were
calculated according to formulas has explained in article.
Results: The average number of drug per prescription was 2.58, percentage of drug
prescribed by generic name: 99.8%, percentage of encounters prescribed Antibiotics:
62.39% percentage of encounters prescribed Injection: 28.96% & the percentage of drugs
prescribed from PHC formulary 99.46%. These findings were almost similar in the three
Health Centers.
Conclusions: Health facilities are one of the most important bases to improve rational
use of Drugs and general practitioners are the major chain in RUD cycle. Results show
that we need to design intervention especially educational interventions to improve two
WHO prescribing indicators, percentage of encounters prescribed Antibiotics &
Injections in this region. For reaching this goals we need to design educational programs
for physicians, pharmacists and people too. These educations can be as workshops,
seminars, conferences or printed materials such as books, leaflets and etc

Abstract
Background: Cirrhosis and portal hypertension influence the hepatic circulation. The purpose of this study was to evaluate the diagnostic accuracy of liver Doppler ultrasonography parameters in cirrhosis.
Methods: This case-control study involved 118 subjects. All case subjects had biopsy-proven hepatic cirrhosis. The controls were healthy people, case-matched for age and gender. All cases and controls underwent Doppler ultrasonographic evaluation. We compared the area under the ROC curve of each parameter for cases vs. controls using Fisher's exact test, with p <0.5 indicating significance.
Results: The means of the following parameters for case vs. control subjects were: frequency of portal venous flow inversion, portal vein diameter 12.67±2.72 vs. 10.59±1.69, and hepatic arterial resistance index 0.81±0.07 vs. 0.74±0.09. The mean hepatic artery pulsatility index (1.87±0.48 vs. 1.34±0.23), was significantly higher among the case subjects (P=0.001). The maximum flow rate of the portal vein was also significantly lower in the case subjects (16.50±5.59 vs. 36.74±8.74 cm/s, P=0.001). We did not observe significant differences in the means of the hepatic artery maximum flow rate and end-diastolic flow rate. For diagnosing cirrhosis, the application of 24.1 cm/s as the cutoff point for the portal vein maximum flow rate, we obtain an accuracy of 95.45% (91.23%-97.70%, CI=95%), whereas a cutoff point of 1.54 or more for the hepatic artery pulsatility index yields an accuracy of 85.71% (79.48%-90.29%, CI=95%). Utilizing a hepatic arterial resistance index of 0.765 or greater is associated with an accuracy of 71.05% (62.81%-78.11%, CI=95%) in diagnosing cirrhosis.
Conclusions: Doppler ultrasonography and assessment of hepatic artery and portal vein parameters are accurate methods in the diagnosis of cirrhosis.
