Objective: To carry out the distribution survey of hard ticks of livestock in Boeen Zahra and Takistan counties of Qazvin province from April 2010 to September 2010. Methods:Nearly about 2 638 sheep, 461 goats and 318 cattle of 38 herds in different geographical areas were searched for tick infestation. Results:The species compositions collected from the livestock of Boeen Zahra and Takistan were Haemaphysalis concinna (0.63%), Haemaphysalis sulcata (12.66%), Hyalomma anatolicum (3.80%), Hyalomma asiaticum (3.16%), Hyalomma detritum (5.70%), Hyalomma dromedarii (28.48%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%), Rhipicephalus bursa (3.16%) and Rhipicephalus sanguineus (3.16%), and for Takistan’s livestock were Hyalomma dromedarii (9.86%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%) and Rhipicephalus sanguineus (3.16%), respectively. Hard ticks compositions in different topographic areas were different. Hyalomma species had the most prevalence in the areas. Conclusions:The veterinary and public health investigation of the above species should be taken.

PURPOSE: Anatomical variations of the external nasal wall are highly important, since they play a role in obstruction or drainage of the ostiomeatal complex and ventilation and can consequently elevate the risk of pathological sinus conditions. This study aimed to assess anatomical variations of the nasal cavity and ethmoidal sinuses and their correlations on cone-beam computed tomography (CBCT) scans. MATERIALS AND METHODS: This cross-sectional study evaluated CBCT scans of 250 patients, including 107 males and 143 females, to determine the prevalence of anatomical variations of the nasal cavity and ethmoidal sinuses. All images were taken using a New Tom 3G scanner. Data were analyzed using the chi-square test, Kruskal-Wallis test, and the Mann-Whitney test. RESULTS: The most common anatomical variations were found to be nasal septal deviation (90.4%), agger nasi air cell (53.6%), superior orbital cell (47.6%), pneumatized nasal septum (40%), and Onodi air cell (37.2%). Correlations were found between nasal septal deviation and the presence of a pneumatized nasal septum, nasal spur, and Haller cell. No significant associations were noted between the age or sex of patients and the presence of anatomical variations (P>0.05). CONCLUSION: Radiologists and surgeons must pay close attention to the anatomical variations of the sinonasal region in the preoperative assessment to prevent perioperative complications.

PURPOSE: This study was performed to evaluate the position of impacted mandibular third molars in different skeletal facial types among a group of Iranian patients. MATERIALS AND METHODS: A total of 400 mandibular third molars in 200 subjects with different types of facial growth were radiographically investigated for their positions according to their types of facial growth on the basis of the beta angle. The subjects were divided into three groups (class I, II, and III) according to ANB angle, representing the anteroposterior relationship of the maxilla to the mandible. Meanwhile, the subjects were also divided into three groups (long, normal, and short face) according to the angle between the stella-nasion and mandibular plane (SNGoGn angle). ANOVA was used for statistical analysis. RESULTS: The mean beta angle showed no significant difference among class I, II, and III malocclusions (df=2, F=0.669, p=0.513). The same results were also found in short, normal, and long faces (df=1.842, F=2, p=0.160). The mesioangular position was the most frequent one in almost all of the facial growth patterns. Distoangular and horizontal positions of impaction were not found in the subjects with class III and normal faces. In the long facial growth pattern, the frequency of vertical and distoangular positions were not different. CONCLUSION: In almost all of the skeletal facial types, the mesioangular impaction of the mandibular third molar was the most prevalent position, followed by the horizontal position. In addition, beta angle showed no significant difference in different types of facial growth.

BACKGROUND: Bloating is a common gastrointestinal complaint which is difficult to treat. OBJECTIVE: This study investigated the efficacy and compliance of a formulation called KAASER comprised of Trachyspermum ammi (L.) Sprague seed, Zingiber officinale Roscoe. rhizome and Piper nigrum L. berry in the treatment of functional bloating. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: A total of 106 patients with functional bloating, between 20 and 50 years of age, participated in this double-blind randomized controlled trial. Patients were divided into 3 parallel groups that received 500 mg of placebo, dimethicone or KAASER, three times a day for 2 weeks. MAIN OUTCOME MEASURES: The frequency and severity of bloating were primary outcomes, while the frequencies of eructation, defecation, borborygmus and early satiation were secondary outcomes. All parameters were evaluated at the beginning (week 0), and also weeks 2, 4 and 10 of the study, through self-report checklists with a scoring system. RESULTS: Among the 84 patients who completed the study, the frequency and severity of bloating (P < 0.001), the frequencies of eructation, defecation and borborygmus (P = 0.03) were significantly improved in the group receiving KAASER (36 patients) compared with the dimethicone (35 patients) and placebo (35 patients) groups, during the 3 phases of follow-up. These significant differences persisted through the 2 and 8 weeks of follow-ups after cessation of medication (week 4 and 10). In early satiation, no significant differences were observed among the 3 groups. CONCLUSION: The results showed that KAASER can be effectively used to treat patients suffering from bloating. Bloating, eructation, defecation and borborygmus in the KAASER group remained significantly improved after 2 and 8 weeks of cessation of medication, making this mechanism an interesting area for further investigation.
