Introduction. The endonasal mucosal or anatomic pathologies could lead to poor functional results and dissatisfaction after rhinoplasty. Although computed tomography (CT) scan has become an integral part of the diagnostic paradigm for patients with pathologies of the paranasal sinuses, the use of CT scan for preoperative evaluation of patients seeking rhinoplasty is up for debate. Our aim in this study was to compare the efficacy of CT scan in diagnosing nasal pathologies with other evaluating tools in patients undergoing rhinoplasty. Design. In this randomized controlled trial study, 74 consecutive patients seeking cosmetic rhinoplasty referred to otorhinolaryngology clinic were randomly assigned into three groups based on the perioperative evaluation method: the CT group, the nasal endoscopy group, and the control group (anterior rhinoscopy only). Surgical planning was made according to perioperative findings, and the identified endonasal pathologies were corrected during the surgery. The functional and aesthetic outcomes of the rhinoplasty were assessed by Nasal Obstruction Symptom Evaluation (NOSE), Rhinoplasty Outcome Evaluation (ROE), and the Visual Analogue Scale (VAS) tools before surgery and at 12-month follow-up. Results. All outcome measures improved significantly in either group toward one year after rhinoplasty (all with p value <0.05). Subjects in the CT group demonstrated greater improvement in the NOSE, VAS, and ROE compared to other two groups (NOSE: p value = 0.17; VAS: p value = 0.024; ROE: p value = 0.042). Conclusions. According to our study, perioperative CT is associated with greater patients’ satisfaction and quality of life after rhinoplasty compared to either nasal endoscopy or anterior rhinoscopy. A preoperative CT scan may improve the outcomes of rhinoplasty.

ObjectiveTo test whether autologous modified mesenchymal stem cells (MSCs) improve recovery in patients with chronic major stroke.MethodsIn this prospective, open-label, randomized controlled trial with blinded outcome evaluation, patients with severe middle cerebral artery territory infarct within 90 days of symptom onset were assigned, in a 2:1 ratio, to receive preconditioned autologous MSC injections (MSC group) or standard treatment alone (control group). The primary outcome was the score on the modified Rankin Scale (mRS) at 3 months. The secondary outcome was to further demonstrate motor recovery.ResultsA total of 39 and 15 patients were included in the MSC and control groups, respectively, for the final intention-to-treat analysis. Mean age of patients was 68 (range, 28–83) years, and mean interval between stroke onset to randomization was 20.2 (range, 5–89) days. Baseline characteristics were not different between groups. There was no significant difference between the groups in the mRS score shift at 3 months (p = 0.732). However, secondary analyses showed significant improvements in lower extremity motor function in the MSC group compared to the control group (change in the leg score of the Motricity Index, p = 0.023), which was notable among patients with low predicted recovery potential. There were no serious, treatment-related adverse events.ConclusionsIntravenous application of preconditioned, autologous MSCs with autologous serum was feasible and safe in patients with chronic major stroke. MSC treatment was not associated with improvements in the 3-month mRS score, but we did observe leg motor improvement in detailed functional analyses.Classification of evidenceThis study provides Class III evidence that autologous mesenchymal stem cells do not improve 90-day outcomes in patients with chronic stroke.Trial registrationclinicaltrials.gov Identifier: NCT01716481.

Basic medical laboratory courses (BMLCs) play an important role in medical educational courses helping the student acquire three important skills of surgical operating, collaborative learning, and problem solving. The outcome-based student assessment (OBSA) is a learning evaluation method that establishes specific evaluation points based on performance of students in three aspects: surgical operating, collaborative learning, and problem solving in the BMLC curriculum practices. The purpose of the present randomized controlled trial study is to explore the efficiency of OBSA program in BMLCs. The 233 students attending BMLCs were randomly divided into 2 groups, 118 in the OBSA group and 115 in the control group. We conducted multiple-choice examination questions (MCQs) test and two questionnaires with the method of two-sample t test for statistics. The results of MCQs in total eight BMLC blocks showed that the academic performance of the OBSA group was significantly better than that of the control group ( P < 0.05). In addition, the average scores of direct observation of procedural skills (DOPS) and mini-experimental evaluation exercise in OBSA group were significantly higher than those in control group ( P < 0.05). The majority of the medical students preferred the OBSA and considered OBSA could effectively improve their surgical operating skills (83.9%), collaborative learning skills (92.1%), and problem-solving skills (91.1%). From the above, OBSA is an effective evaluation method for the implementation of the BMLC curriculum.

Introduction. Determination of borders of the postcricoid tumors is of great significance during preoperative analysis, because it can be of considerable influence on operative treatment and its planning. Therefore, exact demarcation, delineation and opacification of tumor zone on CT analysis is crucial. Material and method. Late CT scan delay of 150 sec and slow vein flow of contrast agents of 1ml/sec is radiological method of choice in preoperative evaluation of carcinoma of the post-cricoid region. For our purposes we used modern MSCT Light Speed GE 64, with slice thick of 2,5mm (retro recon of 0,625) with software postprocesing. Results and discussion. In our study, we have detaily analyzed 25 patients with clinically proved carcinoma of hypopharynx, of which 8 had the hardest form of tumor. Control group were patients to whom CT scan was done by standard protocol and CT time scan of 50 sec. With all 8 of them, scanned by protocol of delay time of 150 sec, was proved a statistically important validity of interpretation and demarcation of tumors. Conclusion. Delay time on CT scanning is proved to be efficient protocol for visualization of neck soft tissues which includes the walls of hypopharynx.

Introduction: The evaluation of effective interventions is still needed to prevent family caregivers of persons with dementia from becoming physically or mentally ill. However, in most existing intervention studies, primary outcomes are not well matched to the treatment goals. Method: A randomized controlled trial (N = 229) was conducted to compare a treatment group (CBT), a treated control group, and an untreated control group. In theses analyses we focused on the primary outcome measurement (GAS) as a perceived treatment success as well as treatment compliance and participants’ evaluation. Results: Results showed that 30.1% achieved complete goal attainment, 39.8% partial goal attainment, and 24.1% declared no change (overachievement 2.4%; deterioration 3.6%). Discussion: The intervention can be considered to have been successful.

Abstract. Background: The public health sector has advocated for more innovative, technology-based, suicide prevention education for the community, to improve their ability to detect and respond to suicide risk. Emerging evidence suggests addressing the bystander effect through the Bystander Intervention Model (BIM) in education material may have potential for suicide prevention. Aims: The current study aimed to assess whether BIM-informed tools can lead to improved readiness, confidence and intent in the community to detect and respond to suicide risk in others. Method: A sample of 281 adults recruited from the community participated in a randomized controlled trial comprising a factsheet designed according to the BIM (intervention group) and a standard factsheet about suicide and mental health (control group). Participants' self-reported detecting and responding to suicide risk readiness, confidence, and intent when presented with a suicidal peer was tested pre- and postintervention and compared across time and between groups. Results: The intervention group had significantly higher levels of detecting and responding to suicide risk readiness, confidence, and intent than the control group at postintervention (all p < .001) with moderate-to-large effect sizes. Limitations: The study was limited by a homogenous sample, too low numbers at follow-up to report, and self-report data only. Conclusion: This study demonstrates BIM-informed suicide prevention training may enhance the community's intervention readiness, confidence, and intent better than current standard material. Further testing in this area is recommended. While results were statistically significant, clinical significance requires further exploration.

SummaryTreatment with streptokinase (‘Kabikinase’) was given to 26 patients with venographically confirmed deep vein thrombosis extending into the popliteal vein or above. Treatment was continued for 4 days and the patients were allocated randomly to oral anticoagulant therapy or a course of treatment with ancrod (‘Arvin’) for 6 days followed by oral anticoagulant therapy. The degree of thrombolysis as judged by further venographic examination at 10 days was not significantly different between the 2 groups. The majority of patients showed clinical improvement but there was no appreciable difference between the groups at 3 and 6 months. Haemorrhagic complications were a more serious problem during the period of treatment with ancrod than during the equivalent period in the control group.

Paranasal Sinus Disease

Aims and Objectives: The study is carried out with an objective to compare the diagnostic nasal endoscopic findings and radiological appearance in patients with paranasal sinus disease. Methods: 50 cases of chronic sinusitis not responding to routine medical line of treatment were selected and operated after being thoroughly investigated by means of nasal endoscopy and CT scan.  Results: Out of 50 cases, 35 underwent bilateral surgery and 15 underwent unilateral surgery, so a total of 85 procedures were carried out. Findings of both the CT scan as well as diagnostic nasal endoscopy were compared to each other and ultimately correlated with operative findings.  Conclusion: In our study, a high association is found between both the modalities of investigation i.e CT scan and diagnostic nasal endoscopy with one scoring over the other in different parameters. Diagnostic nasal endoscopy is found to be highly sensitive investigatory modality for parameters like frontal recess, spheno-ethmoid recess and hiatus semilunaris, where as CT scan is found to be highly sensitive for parameters like maxillary sinus, uncinate process and posterior ethmoids. So, a case of sinus disease should be diagnosed as early as possible using both these modalities as together they complement each other. Early diagnosis and effective management cures the pathology and prevents disastrous complications.

School children can act as change agent not only for families but for community. The study aimed to assess effectiveness of information package on knowledge and practices of parents/family members of school children studying in Govt. Sr. Sec. School on food hygiene in Dhanas and Daddu Majra Colony, UT, Chandigarh. A non-randomised controlled trial was conducted on 201 school children studying in VIIth standard and their parents/family members. Purposive sampling technique was utilised to enrol 101 in case and 100 participants in control group. Interview schedule for knowledge assessment and observation checklist for assessing the practices of parents/ family members was used. Pre assessment of both the groups was done by a home visit. Experimental group school children were educated on food hygiene as per the protocol. Pre and post-test knowledge of school children on food hygiene was assessed and were asked to disseminate the information to their parents/family members.  After 15 days, second time home visit was done to the parents/family members of both the groups for the post assessment of knowledge and practices. Significant improvement in knowledge and practices of parents/family members related to food hygiene was observed. Hence, school children can be an effective tool in health related knowledge dissemination which can further promote healthy practices.

The Impact

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

History Of

Mother-infant attachment is an intimate, lasting and satisfying relationship that leads to better cognitive, emotional and social growth of the infant. The aim of this study was to determine the effects of breastfeeding training by role-play on mother-infant attachment behaviours. This research was a randomised clinical trial (parallel design). Inclusion criteria were: no history of mental disorders; ability to read and write the Persian language to complete the questionnaire; no history of drug and tobacco intake in primigravida women. The sample comprised 100 pregnant women (in 2 groups), selected through simple random sampling at healthcare centres. The researcher reviewed prenatal care registries of selected healthcare centres and extracted the names of pregnant women in their early third trimester. The data were imported into randomisation software. The control group received routine breastfeeding training, while the intervention group received routine training together with training through role-play. The data collection tool was the Maternal Behaviour Inventory Questionnaire. Consequently 75 samples were analysed in SPSS16. Independent t-tests and chi-square tests were used to examine the difference between the two groups. Results showed that the mean score of mother-infant attachment one week after delivery was significantly higher in the intervention group in comparison to that in the control group (p<0.001). No significant difference was observed between the two groups in maternal age, age of marriage, neonatal gender, maternal employment and education, number of parity, and number of abortions (P>0.05). Since breastfeeding training through role-play could affect mother-infant attachment, it is suggested that this type of training should be provided for pregnant women to promote mother-infant attachment and exclusive breastfeeding.
