The purpose of the present study was to compare the effect of sciatic nerve mobilisation on muscle flexibility among diabetic and non-diabetic sedentary individuals. The study was a pre-post experimental-group design. A sample of 40 sedentary subjects was assigned into two groups; Group A (diabetics: 10 males and 10 females) and Group B (non-diabetics: 10 males and 10 females). Both groups were tested for hamstring and calf flexibility following which sciatic nerve mobilisation was given to the most affected lower limb in terms of reduced hamstring and calf flexibility. Hamstring flexibility was checked by active knee extension test and calf flexibility was checked with the distance-to-wall technique using a tape measure. It was a two-week program in which subjects were given sciatic nerve mobilisation using sliders technique after which flexibility was checked. Three sessions per week were given for two weeks and muscle flexibility of hamstring and calf was measured after the intervention. The present study findings reveal that sciatic nerve mobilisation by sliders technique when given to diabetic and non-diabetic groups of sedentary individuals for two weeks, enhance patient outcomes in both the groups in terms of increase in hamstring and calf flexibility, but results were more significant in non-diabetic individuals as compared to diabetic individuals. In conclusion, sciatic nerve mobilisation resulted in an increase of muscle flexibility of hamstring and calf muscles in both groups.

Introduction: Previous equipments used to study cornea were mostly Placido based which could only analyse anterior surface of cornea, while Pentacam is based on elevation based imaging method that helps to study the curvature of cornea, its elevation and thickness profile more accurately. There are numerous studies published to study the thickness of cornea, this study outlines the importance of changes introduced in various corneal parameters with age which in itself is an important factor with possible positive correlation. Aim: To determine various corneal parameters and to interpret the variations in these with increasing age. Materials and Methods: This cross-sectional study included a cohort of 60 healthy patients attending Outpatient Department of Ophthalmology from July 2019 to February 2020. Two sets of values were determined, studied and compared between different age groups. First set of values included, keratometry values in the flat (K1) and steep (K2) and maximal keratometry values of the front surface (Kmax). Second set of values included, Anterior Elevations (AE), Posterior Elevations (PE), PE minus AE from Best Fit Sphere of 8 mm (BFS) and PE from the Best-fit Toric Ellipsoid (BFTE), apex thickness (CCT), pachymetry at the thinnest-point thickness (TCT),average corneal Pachymetry Progression Indices (PPI avg) and average Ambrosio’s Relational Thickness indices (ART avg). Based on age, three groups were created with 20 participants in each, Group A with age 18 to 25 years, Group B with age between 26 and 40 years and Group C with age more than 40 years. Scanning of all study subjects was done using Pentacam. Mann-Whitney U test and Spearman correlation test were used for the statistical analysis. Results: The average age was 21±2.42 years in group A, 30.9±4.3 years in group B and 42.45±1.65 years in group C. When AE, PE and PE-AE values were compared among three age groups, results were highly significant with p-value <0.00001. Thus, the elevation indices from BFS were found to be correlated with age. On comparison of PPI average between group A and B, group B and C values were statistically insignificant (p-values 0.51 and 0.19, respectively).Though in comparison between Group A and C, average corneal PPI avg was found to be of statistical significance (p-value=0.048). Average ART indices (ART avg) was found to produce highly statistically significant results among 3 groups (p-value <0.00001). Conclusion: The corneal parameters are significantly altered from their normative values with age. This study outlines that elevations indices and avg ART values are significantly altered with increasing age.

Osteoarthritis (OA) knee is a long-term chronic disease characterized by the destruction of articular cartilage and underlying bone. Pain, limitation of motion and functional impairment are common clinical features. Poor hamstring flexibility is a major problem for patients with OA knee. The stretching of the hamstring is a necessary intervention in the management of the OA knee. This study is therefore intended to compare the effectiveness of static stretching vs PNF stretching for pain, hamstring flexibility and functional mobility in OA Knee patients. 30 patients were randomly divided into two groups. Group A (N=15) received PNF stretching, wax therapy and isometric quadriceps exercises, and group B (N=15) received static stretching, wax therapy and isometric quadriceps exercises. The intensity of the pain was measured using the NPRS (Numerical Pain Rating Scale), hamstring flexibility by AKET (Active Knee Extension Test) and functional mobility by TUG (Timed up and Go) test. The results showed that significant differences in NPRS (Z=4.64, P=0.001), AKET (t=9.61, P=0.001) and TUG (t=8.19, P=0.001) were observed in group A patients when compared to group B. In conclusion, the PNF stretching treatment program is effective in reducing pain, improving hamstring flexibility and functional mobility in patients with OA knee compared to static stretching.

Background: Bronchiolitis is an acute, highly communicable lower respiratory tract infection. A variety of agents ranging from nebulised racemic epinephrine, salbutamol and routinely available levoepinephrine have been tried. The Present study was aimed at comparing the effectiveness of adrenaline and salbutamol in acute bronchiolitis in children aged 2 months to 2 years. Materials and Methods: The Present study was conducted at Nobel medical College Teaching Hospital over the period of one year from Feb 2018 to Jan 2019. Two different cohorts were identified in which clinically diagnosed cases and were grouped into Group A and Group B to receive the different drugs as per the study protocol. Respiratory Distress Assessment Instrument (RDAI) Scores was used for clinical assessment. Results: The age of the patients ranged from 2 months to 24 months with a median of 8 months. The males constituting about 57.42% of the study population of 155 patients. On comparing the prenebulisation variables with 10 and 30 minutes post nebulisation values, it was found that Both adrenaline and salbutamol caused overall significant improvement in RR (p-value <0.00001 in both groups) except in the age group of 19-24 months. Adrenaline was seen to be superior to salbutamol in decreasing the RR (p<0.0001) except for children in the age group of 19-24months. Adrenaline also caused greater rise in heart rate in comparison to salbutamol in all age groups. Conclusion: This study concludes that Adrenaline was seen to be superior to salbutamol in decreasing the RR and RDAI, although it showed variance with age.

Hamstring Flexibility

Hamstring tightness is commonest cause of altered biomechanics of ankle, knee, hip and spine. Long persistent tightness results in pain, decreased range of motion and others pathologies in knee joint. Stretching techniques are used to treat muscle tightness. In clinical settings, different stretch holding timesare used to treat hamstring tightness. The purpose of the study was to determine effects of different static stretch holding-times on hamstring muscles flexibility and their impacts on improving range of motion (ROM) of knee extension in adults. This experimental work was conducted on students of University of Lahorefrom December 2013 to March 2014. The study comprised of 60 subjects with asymptomatic tightness of hamstrings muscles and subjects were aged between 18-26 years (irrespective of their gender). Range of motion at knee joint was measured by universal goniometer before the commencement of stretching technique. Static stretching was applied to group A, B and C with 30, 60 and 90 seconds holds, respectively. Stretches were exerted at frequency of three sessions per week and three repetitions per session. Reevaluation of ROM was performed after 4 and 6 weeks. The mean values of ROM of knee extension showed gainin range after applying static stretching at 30s, 60s and 90s holding times. By applying repeated measure analysis of variance (ANOVA), the p-values were found to be statistically significant (p<0.001) for static stretching techniques with 30s, 60s, 90s holding times, respectively. Based on these finding, it is plausible toconclude that application of static stretching at holding times of 30, 60 and 90 seconds can significantly improve the ROM of knee extension. Stretching techniques with different holding times were equally effective in improving knee extension and gaining hamstring flexibility in adults.

SummaryBlood coagulation in a strain of rabbits designated as Watanabe heritable hyperlipidemic (WHHL) rabbits was examined. The activities of vitamin K-dependent clotting factors, contact factors and clotting factor VIII (F VIII) and the fibrinogen level were significantly higher in WHHL rabbits than in normolipidemic rabbits (all age groups). Values for vitamin Independent clotting factor were already higher at 2 months of age. Contact factors and fibrinogen levels increased age after 5 to 8 months. F VIII increased between 5 and 8 months and then decreased. At 2 months of age, WHHL rabbits were divided into two groups. Group A was fed standard rabbit chow and group B standard rabbit chow containing 1% probucol. Probucol prevented the progression of atherosclerosis in group B in the absence of a significant reduction in plasma cholesterol level. F VIII and fibrinogen levels were statistically decreased in all rabbits at all ages in group B (P<0.05). These differences in clotting factors between the two groups were most obvious at 8 months (P<0.02).We conclude that vitamin K-dependent clotting factors may increase with hyperlipemia and that increases in F VIII and fibrinogen may be closely related to the progression of throm- boatherosclerosis.

Background: Frozen shoulder is disorder of the connective tissue that limits the normal Range of motion of the shoulder in diabetes, frozen shoulder is thought to be caused by changes to the collagen in the shoulder joint as a result of long term Hypoglycemia. Mobilization is a therapeutic movement of the joint. The goal is to restore normal joint motion and rhythm. The use of mobilization with movement for peripheral joints was developed by mulligan. This technique combines a sustained application of manual technique “gliding” force to the joint with concurrent physiologic motion of joint, either actively or passively. This study aims to find out the effects of mobilization with movement and end range mobilization in frozen shoulder in Type I diabetics. Materials and Methods: 30 subjects both male and female, suffering with shoulder pain and clinically diagnosed with frozen shoulder was recruited for the study and divided into two groups with 15 patients each based on convenient sampling method. Group A patients received mobilization with movement and Group B patients received end range mobilization for three weeks. The outcome measurements were SPADI, Functional hand to back scale, abduction range of motion using goniometer and VAS. Results: The mean values of all parameters showed significant differences in group A as compared to group B in terms of decreased pain, increased abduction range and other outcome measures. Conclusion: Based on the results it has been concluded that treating the type 1 diabetic patient with frozen shoulder, mobilization with movement exercise shows better results than end range mobilization in reducing pain and increase functional activities and mobility in frozen shoulder.
