ABSTRACTObjective:To determine whether a visual classification of anterior malar support using vector relationships is supported by cephalometric analysis.Materials and Methods:Forty white subjects between the ages of 10 and 12 years, without craniofacial syndromes or previous orthodontic treatment, were equally divided into groups based on visual assessment of negative and positive vector relationships. Group A comprised 20 subjects (10 male, 10 female) exhibiting a positive vector relationship. Group B comprised 20 subjects (10 male, 10 female) displaying a negative vector relationship. Sella-nasion-orbitale (SNO) angulations were measured to evaluate the subjects' anteroposterior position of the malar eminence relative to the cranial base. Gender differences and significant differences in SNO measurements between groups A and B were assessed with Mann-Whitney U-tests.Results:There was no statistically significant difference between genders. SNO angulations in the negative vector group were smaller than the positive vector controls by an average of 6.0 degrees, and the difference was highly significant (P < .0001).Conclusion:Compared with subjects exhibiting a positive vector relationship, individuals displaying a negative vector relationship had significantly reduced malar support. Anterior malar projection can be effectively classified through visual assessment of vector relationships.

Effect Of Age

Objectives: The main goal of this research was to determine the differences between the values of intraocular pressure (IOP) in the supine and sitting positions, and to assess the effect of age and cardiovascular parameters. Methods: Seventy-two healthy adults were enrolled and classified into age groups: 20–30 years (group A), 31–40 years (group B), and 41–71 years (group C). Corneal biometry and cardiovascular parameters, such as heart rate (HR), were measured. IOP measurements were taken in the sitting position (IOPS) and in the supine position (IOPL) using the iCare® Pro tonometer. Results: A significant difference between the IOPS and IOPL in the entire cohort was found ( p < 0.001). Regarding the age subgroups, a significant difference ( p < 0.001) between the IOPS and IOPL was obtained in group A (2.6 ± 1.6 mmHg) and group C (1.5 ± 1.3 mmHg). There were no significant differences in the IOPS between groups. The highest IOP values were obtained for group A. The correlations between HR and IOPS are statistically significant for group A and group B, and for HR and IOPL-S for group B only. Multivariate analysis showed that HR has a significant influence on the difference in IOP in the two body positions. Conclusion: A statistically significant difference between the effect of age and the values of IOPS and IOPL was shown. Cardiovascular parameters showed some relevant statistical dependencies, but with a rather marginal significance in young people. The influence of body position for the measurement of IOP for healthy subjects does not seem to matter, despite the fact that there are some dependencies that are statistically significant.

Introduction: Pharyngeal packs are commonly used to prevent of postoperative nausea and vomiting (PONV) and Sore throat during nasal surgery following tracheal intubation. the aim of this study is evaluation of effectiveness of pharyngeal packing in the prevention of PONV. Materials and methods: This study with random sampling performed on 120 adult patients scheduled for routine nasal surgery referred Boo – Ali hospital in Tehran, Iran from March 2011 to March 2012. the study was approved in the ethical committee of Azad University and written informed consent to participate in the study. All subjects randomly allocated to Group A or Group B to have and not to have pharyngeal packing during surgery, Respectively.The incidence of PONV and sore throat in the recovery room,at 2 and 6 h were recorded by a 100 mm long visual analogue scale (VAS). Data were analysed using non-parametric tests in SPSS 18. Significant difference was set at p<0.05. Results: The average age of patients was 27.6 ± 7.1 years. The average of age in Group A was 29.2 ± 2.8 years and in Group B was 27.4 ± 3.2 years. The difference in throat pain scores in the two groups at each assessment time was statistically significant. The difference in PONV scores were not statistically significant. Conclusion: The usage of pharyngeal packing during nasal surgery leads to decreased incidence of sore throat in experiment group compared with the control group. Also has no effect on the incidence of PONV. [GMJ. 2012;1(1):24-28]

Abstract Background: Balanced complex chromosome rearrangements (BCCR) are balanced chromosomal structural aberrations that involve two or more chromosomes and at least three breakpoints. It is very rare in the population.The objective is to explore the difference of influence of three types of BCCR on early embryonic development and molecular karyotype.Results:Twelve couples were recruited including four couples of three-way rearrangements carriers (group A), three couples of double two-way translocations carriers (group B) and five couples of exceptional CCR carriers (group C). A total of 243 oocytes were retrievedin the seventeen preimplantation genetic testing (PGT) cycles, and 207 of these were available for fertilization.After intracytoplasmic sperm injection, 181oocytes normally fertilized. The rates of embryos forming on day3 in three groups were 87.88%, 97.78% and77.14%, which was significantly different (P=0.01). Compared with group B, the rate of embryo formation was statistically significantly lower in group C(P=0.01).Furthermore, the rates of high-quality blastocysts in three group were 14.71%, 48.15% and 62.96%, respectively, which was significantly different (P=0.00). Compared with group B andC, the rate of high-quality blastocysts in group A was statistically significantly lower (P=0.00;P=0.00). Comprehensive chromosome analysis was performed on 83 embryos, including 75 trophectodermcellsand 8 blastomeres. Except 7 embryos failed to amplify, 9.01%embryos were diagnosed as euploidy, and 90.91% were diagnosed as abnormal. As for group A, the euploid embryo rate was 10.71%and the abnormal embryo rate was 89.29%. In group B,the euploid embryo rate was 3.85%, the abnormal embryo rate was 96.15%. The euploid embryo rate was 13.04%, the abnormal embryo rate was 86.96% in group C.There were no significant differences among the three groups (P = 0.55).Conclusions:The lowest rate of high quality blastocysts has been for three-way rearrangements and the lowest rate of euploidy has been for double two-way translocations, although no significant difference. Different types of BCCR maybe have little effect on the embryonic molecular karyotype. The difference of influence of BCCR on early embryonic developmentandmolecular karyotypeshould be further studied.

The objective of this study was to observe the clinical effect of Chitosan nanoparticles therapy on Helicobacter pylori (HP) infection. Three treatment groups (A, B, and control group C) were randomly assigned with 60 cases of HP each, making 180 cases. Group C received standard triple therapy (omeprazole + amoxicillin + clarithromycin), group A got a routine dose of Chitosan nanoparticles plus triple therapy, and group B got a high dose of Chitosan nanoparticles plus triple therapy. The course of treatment in each group was 7 days. The eradication rate, clinical efficacy and adverse reactions were observed. Up to 172 patients finished the experiment, with 59 patients in Group A, 57 in Group B and 56 in Group C. In a total analysis set (FAS), the eradication rates of HP in Group A, Group B and Group C were 80.00%, 80.70%, and 71.67%, respectively. There was no significant difference between the two groups (P > 0.05). In accordance with the PPS, the HP eradication rates of group A, B, and C were 81.36%, 80.70% and 76.79%, respectively, and there was no significant difference between the two groups (P > 0.05). The clinical efficacy of group A, B, and C were 91.67%, 91.23%, and 70.00%, respectively. The differences among the three groups were statistically significant (P < 0.05). In accordance with the PPS, the clinical efficacy of group A, B and C was 93.22%, 91.23%, and 75.00%, respectively. With a P-value of less than 0.05, the results indicated that the difference between the two groups was statistically significant. There were 21 adverse reactions in the experiment, including 3 in group A, 6 in group B, and 12 in group C. The difference was statistically significant (P < 0.05) between group A and B compared with group C, the difference was statistically significant (P < 0.05); the difference between group A and group B was statistically significant (P < 0.05). In conclusion the therapeutic effect of Chitosan nanoparticles and oral liquid, combined with triple therapy on HP infection is satisfactory, with less adverse reactions are. However, the findings suggest that it is not desirable to use a high dose Chitosan nanoparticles and oral liquid.

Background: Supraglottic airway device results in less hemodynamic responses during laparoscopic surgery but supraglottic airway device to be used should have higher oropharyngeal seal pressure than peak pressure for effective ventilation as laparoscopic surgery also leads to higher airway pressure. In this study the efficiency of the I-gel with SLMA is compared in patients undergoing laparoscopic cholecystectomy surgeries.Methods: Sixty patients were randomized in to two groups, group A where I-gel was considered for airway management and group B where LMA Supreme was the device chosen for airway management.Results: Oropharyngeal seal pressure was significantly lower in group A than group B, 5 minutes after insertion of airway device it was 24.90±3.03 cm H2O and 27.30±3.41 cm H2O in group A and group B, respectively and 5 minutes after creation of pneumoperitoneum it was 25.53±3.17 cm H2O and 27.57±3.36 cm H2O in group A and group B, respectively. There was significant difference in the difference between inspiratory and expiratory tidal volume between the groups at all the time periods being higher in group A than group B. Hemodynamics were comparable between the two groups. Time taken to insert the airway device and Ryle’s tube insertion was significantly lesser in group B in comparison to group A. The percentage of complications was higher in group A than group B with no significant (p>0.05) association.Conclusions: Both the I-gel and SLMA devices can be used safely in laparoscopic cholecystectomy in non-obese patients. But in SLMA group oropharyngeal seal pressure was higher with lesser leak volume in comparison to I-gel group.

Background: Damage to porcelain restorations such as fractures requires a repair that can be performed either directly or indirectly. Direct repair involves directly performing restoration of fractured porcelain with a composite resin application. This technique has more advantages than indirect repair because it requires no laboratory work and can be completed during a single visit. Silane, on the other hand, has been widely used and is reported to increase porcelain and composite resin attachments during the direct repair process. Purpose: This study aimed to determine the differences in shear bond strength between porcelain and composite resin during the administering of 4% and 19.81% silane. Methods: 27 porcelain samples were divided into three groups, namely: Group A - 4% silane, Group B - 19.81% silane and Group C - no silane, prior to the application of composite resin. Each sample was tested for shear bond strength by means of Autograph and fracture analysis performed through stereomicroscope and scanning electron microscope tests. Data analysis was subsequently performed using an ANOVA test. Results: There was a significant difference between the three groups with p=0.000 (p<0.005). The lowest bond strength was found in the group without silane, while the highest was in the group with 4% silane (p<0.005). Conclusion: The use of 4% silane can produce the highest shear bond strength of porcelain and resin composite.

Cases of craniosynostosis usually fall into well-demarcated categories: those related to a syndrome or identified by a combination of suture involvement and morphological appearance. Between 1976 and 1995, 53 (3.6%) of 1474 cases in the craniofacial databank were assessed and designated as nonsyndromic but unclassifiable. The records and radiological studies obtained in these patients were retrospectively analyzed and comparisons were made with patients classified in the databank as having simple craniosynostoses. It proved possible to divide the formerly unclassifiable cases into two groups: those with “two-suture disease” (Group A) and a “complex” group (Group B) in which more than two sutures were affected. Group A consisted of 36 cases (68%) of patients presenting with clear evidence of simultaneous involvement of two sutures but with no progression over time to suggest a more diffuse pansynostosis. Suture involvement was as follows: 17 of 36 sagittal plus one coronal; seven of 36 sagittal plus metopic; six of 36 sagittal plus one lambdoid; and six of 36 metopic plus one coronal. The only significant difference between the Group A cases and the cases of simple craniosynostoses was in the percentage requiring a second operation (24% vs. 5%, p < 0.0001). Group B consisted of 17 cases in which the patients presented at a slightly earlier age (mean 1 year) with severe morphological changes and multiple suture involvement. At the time of surgery, six of 17 patients showed large areas of lacunae within the cranial vault, making craniectomy the only option. In Group B, 10 of 17 patients displayed bilateral lambdoid plus sagittal suture involvement resulting in marked occipital recession posteriorly, whereas anteriorly in six of these 10 patients there was a massive frontal bone associated with posteriorly located coronal sutures. In contrast, there were also four patients in Group B with bilateral coronal plus metopic involvement resulting in a small frontal bone. There was a trend toward a lower intelligence quotient and a worse morphological outcome in the patients in Group B, but again the only result attaining statistical significance when compared to the databank was the rate of second operation (37.5 vs. 5%, p < 0.0001). “Two-suture synostosis” is a relatively straightforward condition and is treatable with standard craniosynostosis techniques. However, possibly as a result of surgical compromise when two sutures are involved, the rate of reoperation is far higher than in simple suture cases. In contrast, patients in the “complex” group presenting with severe multisuture involvement require a more tailor-made approach to their management that often entails a second procedure.

Objective: To compare the Salbutamol alone and Ipratropium Bromide supplemented Salbutamol in children with exacerbation of asthma in terms of PEFR. Study Design: Randomized Controlled Trial. Setting: Pediatrics Emergency, KRL Hospital Islamabad. Period: 1st August 2016 to 31 January 2017. Material & Methods: Group A patients were given only Salbutamol (0.15mg/kg per dose with minimum 2.5 mg, maximum 5 mg/dose). Group B was given Ipratropium Bromide supplemented Salbutamol (250 mcg/dose for <20 kg while 500 mcg/dose for >20kg of Ipratropium Bromide with same dose of Salbutamol as prescribed for Group A). Baseline spirometry was performed on each patient and after measurement of baseline peak expiratory flow. The outcome was measured by Peak flow meter and reassessed at 60 minutes. Results: Comparison of salbutamol alone and ipratropium bromide supplemented salbutamol in children with exacerbation of asthma in terms of PEFR shows that 40.5 + 4.28 in Group-A and 59.5 +4.75 in Group-B, P-value was calculated as 0.0001, showing a significant difference between the two groups while the difference in increase was recorded as 19%. Conclusion: We concluded that salbutamol alone is significantly less effective when compared with Ipratropium Bromide supplemented Salbutamol in children with exacerbation of asthma in terms of PEFR.
