PURPOSE: To evaluate swine vocal fold healing in a period of 30 days after topical mitomycin-C application. METHODS: Twelve swine underwent exeresis of mucosal flaps from the free edge of the anterior third of both vocal folds with a cold instrument (laryngeal scissors). The animals were divided into two groups: EG (Experimental Group), consisting of 6 animals undergoing topical MMC application (4 mg/dL) on the operated area for 4 minutes; CG (Control Group), 6 animals undergoing topical saline solution application on the operated area for 4 minutes. After 30 days, the animals were sacrificed and the larynges were collected and examined for the presence of synechiae as well as a histological immunohistochemical assessment of immature and mature collagen deposition, number of blood vessels and myofibroblasts. RESULTS: Mature collagen deposition in the EG was 452.12 μm² and 1332.31μm² in the CG; immature collagen deposition was 1511.73μm² in the EG and 1020.61μm² in the CG. The number of myofibroblasts was 1.556 in the EG and 3.583 in the CG. The number of blood vessels was 2.565 in EG and 6.917 in the CG. There were no synechiae in the two studied groups. CONCLUSIONS: There was an increase in immature collagen deposition in the experimental group when compared with the control group. There was a decrease in mature collagen deposition in the experimental group when compared with the control group. There was a decrease in the number of myofibroblasts in the experimental group when compared with the control group. A decrease in blood vessels was observed in the experimental group when compared with the control group. There was no synechia formation in either studied group.

The study pertains to the parenting stress, which is believed to be the resultant of child disability and further assesses the needs of the families across selected pockets of Himachal Himalaya. Perceived Stress Questionnaire (PSQ) and Need Assessment Scale were used for the purpose. For assessing the stress level among the parents, PQS was administered among two hundred parents having disabled children, herein called experimental group and two hundred parents with normal children, herein called control group. A three point Need assessment scale was used to measure the needs of 200 families on five different parameters. The result of t-test shows the significant difference between experimental and control groups indicating that the parents of disabled children experience more stress than their control counterpart. The study indicates that people need proper guidance and information regarding a child’s disability, nutritional requirements of a child, vocational training and child management. There is a need for proper counselling for parents suffering from stress and creating consciousness among parents of children with disabilities and in the society.

Background: Obesity is a prevailing metabolic disorder that affects the functioning of the male reproductive system. Excessive adipose tissue enhances reactive oxygen species generation and is linked with male infertility. Spinach has demonstrated antioxidant effects. The present study was conducted to determine the antioxidant effects of spinach on sperm parameters in obese Sprague Dawley rats. Subjects and methods: This randomized control study was conducted at the animal house of the National Institute of Health Islamabad, Islamic International Medical College, Cosmesurge International Hospital, Rawalpindi, and Apollo lab, Islamabad, Pakistan from April 2016 to March 2017. Forty male Sprague Dawley rats having an age of 8 weeks and weight 160-200g were tagged from number 1 to 40. Every third rat was randomly allocated to control Group A (n=13) and remaining into the Experimental group (n=27). Rats of control Group A was given a standard diet while a high-fat diet was given to Experimental group rats to induce obesity for the duration of six weeks. Weight (g) was measured weekly and obesity was confirmed when rats attain more than 20% weight when compared with that of rats of control Group A. Then, after obesity induction, the experimental group was alienated into the obesity control group (Group B) and spinach treated group (Group C). For sample, rats of Group A and Group B were sacrificed, and the cauda epididymis of each rat was placed in a Petri dish containing normal saline and cut into pieces to allow the release of sperm and then sperm parameters (sperms concentration, motility, and morphology) were recorded under the microscope. Then, spinach (5% hot water extract) along with the persistence of fat diet was administered to Group C for 4 weeks and finally, sperm parameters were measured in this group. Results: Sperm concentration/ml, motility (%), and normal morphology (%) of Group B rats were significantly decreased as compared to Group A rats. However, sperm concentration/ml, motility (%), and normal morphology (%) of Group C (spinach treated group) rats was significantly increased (p<0.001) as compared to Group B (obesity control group) rats after administering spinach. Conclusion: The addition of Spinach in a normal diet regimen restores normal sperm morphology, improves sperm motility and concentration.

This study investigated the effectiveness of a peer tutoring program that was implemented for Basic Solid Mechanics course, as an intervention program to improve students’ performance in the course. Ten tutors were chosen to provide tutoring services to an experimental group of 36 tutees. Tutees were required to answer an entry test before the intervention program, and another exit test after the program. A control group which shared the same instructor in their lecture classes was included in the study. Comparison between the performances for entry and exit tests of both experimental and control groups were made. Analyses showed an increase in the percentage of students that passed the exit test from the experimental group. The average marks for the experimental group in the exit test also increased, compared to their marks in the entry test. A Mann- Whitney U test conducted indicated a significant difference between the gain scores of the experimental group and control group. A further metaanalysis revealed a large effect size, signaling the practical significance of the results. The findings demonstrated the effectiveness of the peer tutoring intervention program on students’ performance of the course.

Objective. Vocal fold polyps are the most common benign laryngeal lesions. Matrix metalloproteinases (MMP) play an important role in the physiological and pathological remodeling of tissues. The most important subgroup of MMP family consists of gelatinases A and B (MMP-2 and MMP-9). The objective of this study was investigation of the expression of MMP-2 and MMP-9 in vocal fold polyps and normal tissue of vocal folds. Material and methods. The immunohistochemical expression of MMP-2 and MMP-9 was investigated in specimens taken by endolaryngeal microsurgery from vocal fold polyps (n=30) and normal tissue of vocal fold (n=13, control group). Expression of MMP-2 and MMP-9, both in epithelium and stroma cells, was graded on a semiquantitative scale, ranging from 0 (no expression) to 6 points (high expression). Results. A statistically significant increase was observed in the expression of MMP-2 in stroma cells (P=0.0176) of vocal fold polyps compared to control vocal fold group, whereas no significant difference in the expression of MMP-2 was found in epithelium cells (P=0.1487). Comparison of expression of MMP-2 and MMP-9 in epithelium cells revealed a statistically significant increase in MMP-9 expression (P<0.01) in both groups. However, there was no statistically significant difference in the expression of MMP-9 between groups of vocal fold polyps and control vocal folds. Conclusion. Expression of MMP-2 in stroma was significantly higher in polyps than in normal tissue of vocal folds. Our data draw attention to the role of MMP-2 in the development of vocal fold polyps and necessity of further investigations to define its function in morphogenesis of laryngeal benign, premalignant, and malignant lesions.

Capsular contracture is the most common complication after insertion of silicone implants during breast implant surgery. The discovery that myofibroblasts play an important role in the formation of hypertrophic scars led to the development of pharmacological drugs such as zafirlukast, which prevents capsular contracture by resisting the above mechanism. As a result, the author sought to investigate the effect of the anti-leukotriene montelukast on capsular contracture. Ten white female New Zealand rabbits, each weighing approximately 3 kg, were used as subjects. Through bilateral incision of the midback area, the prostheses were inserted on the subpanniculus carnosus plane. Once the silicone prostheses had been inserted, the right implant was injected with 10 mL of montelukast (10 µg/mL), and the left implant was injected with 10 mL of normal saline. Eight weeks after the procedure, the capsular pressure was measured via tonometry using a circular glass piece weighing 42.7 g. The tissue samples were then extracted, and their thicknesses were measured using hematoxylin-eosin stain and Masson trichrome stain. The average pressure was 4.23±0.99 mmHg in the control group and 3.71±0.51 mmHg in the experimental group, a statistically significant difference (p = 0.02). The average capsular thickness was 947.938±300 µm in the control group and 709.672±274 µm in the experimental group, a statistically significant difference (p = 0.028). The author confirmed that montelukast injections during silicone prosthesis insertion decreased the formation of capsular contracture.
