Visual Outcome of Open Globe Injuries in Paediatric Patients

Background: To determine visual outcome of open globe injuries in children.Methods: In this descriptive study children, between 4-16 years (n=80), who had open globe injury and who presented within one week of injury, were included . All patients underwent surgical repair surgery. Corrected post-operative visual acuity at 4 weeks was recorded. Effect modifiers like age, gender, mechanism of injury and time delay in presentation was controlled by stratification. For post stratification chi square was applied. p-value of ≤ 0.05 accepted as statistically significant.Results: Visual improvement was observed in 70% (n=56) of patients as per operational definition, which was significantly higher in patients who presented before 24 hours (p<0.05). No other significant association was found. Conclusions: Open globe injuries require emergency surgery as a standard of care. Visual improvement was observed in 70% in this study which was significantly associated with earlier presentation (<24 hours

Identification of the Students’ Misconceptions about the Digestive System

The aim of this study is to determine the students’ misconceptions about the digestive system. In this quantitative research, the study group comprised totally 259 sixth-, seventh-, and eighth-grade students. The data were collected through a three-tier diagnostic test and analyzed in terms of scientific knowledge, the lucky guess, lack of knowledge, and misconception levels of students on digestive system. According to the findings, 20.1% of the students’ answers were in the scientific knowledge category and 9.1% were in the lucky guess category. On the other hand, 39.7% of the answers were in the lack of knowledge category and 26.0% were in the misconception category. The most prominent findings in the study were the students’ misconceptions in a few questions, especially about physical and chemical digestion. In addition, some students did not fully understand the distinction between the excretory and digestive organs and the functions of some accessory. They also gave incorrect answers about the organs where the digestion of proteins, carbohydrates and fats begins and ends. At the end of the study, suggestions were made to eliminate the misconceptions

Trans-radial approach for coronary angiography in an adult postoperative patient with tetralogy of Fallot with complex anatomy

2015 BMJ Publishing Group Ltd.A 42-year-old, postoperative patient with tetralogy of Fallot (TOF) with right-sided aortic arch, presented with heart failure secondary to left ventricular dysfunction, severe valvular regurgitation and residual ventricular septal defect (VSD). After initial stabilisation, he underwent successful coronary angiography through a trans-radial approach followed by aortic valve replacement, pulmonary valve and VSD repair, and was discharged home in stable condition. This case report highlights the trans-radial approach as a feasible option for coronary angiography in postoperative patients with TOF with right-sided aortic arch

Bringing About a Behavioural Change in Providers to Meet the Reproductive Health Needs of Clients

The international conference on population and development held in Cairo in 1994 has became a historical turning point in the way population policies and programmes are perceived and sexual and reproductive health services are conceptualised and delivered. Inherent in the ICPD plan of action is the concept of care that recommends providing a range of reproductive health services to both men and women, that are safe and effective, and that satisfy clients, needs and wants. Clients are far more likely to use services that are of high quality. Achieving quality care requires complying with high technical and ethical standards (such as freedom of choice, informed consent, and freedom from coercion and abuse) and providing services at costs that are affordable to both clients and health care system. The most common barriers to quality are negative provider attitudes or behaviours, poor interactions between clients and providers, a lack of essential drugs and supplies in facilities, and delays in referrals to other necessary services. Pakistan has among the worst reproductive health indicators in the developing world. It has lagged behind many of its neighbours in terms of its social indicators. Access to health and educational facilities, especially in the rural areas has remained outstandingly weak. Maternal and infant mortality rates are unacceptably high at above 500 per 100,000 and 80 per 1000 births, respectively. Malnutrition, anaemia and reproductive tract infections are widely prevalent in women.

Assessment of Coefficient of Variation of Emitters Flow Rate with Respect to Design, Manufacturer and Plugging in Installed Drip Irrigation Systems at Selected Sites of Peshawar Valley

The study was conducted to assess the performance of drip irrigation systems installed at Charsadda, Malakand Agency and Nowshera. The performance parameters of the drip irrigation system included the coefficient of variation of emitters flow rate with respect to design of manufacturer, hydraulics, grouping of the emitters, plugging, uniformity, efficiency, adequacy and estimated design discharge , measured Cv(H) values for all plots are less than 30%.  Hydraulic design seems to be only one of the minor factors in the evaluation of overall uniformity of a micro-irrigation system. Having the Cv(HM) variations are only about 0-7% except plot No.1 of Nowshera farm that is 24.16%, expressed by Cv. micro-irrigation system can be designed hydraulically to maintain emitter flow uniformity within 10% or 20% emitter flow variations. Grouping variation of emitters flow is 0-4% in Charsadda and Malakand Agency farm. In plot No.1 of Nowshera farm its 20.60% while in plot No.2 and 3 it is 0%. The group coefficient is affected by emitters flow rate that is uniform. In Charsadda and Malakand Agency farm the overall effect of hydraulic, manufacturer and grouping are 0-7.11% and 0-1.02% in plot No.3 and 2 of Nowshera farm, in plot No.1 it is 31.75%. Among all the factors affecting the uniformity, plugging is the most significant factor. The Cv(P) is 0% resulted from partial plugging. 5-10% plugging could produce Cv(P) of 23-33%. This system has no plugging, which implies that the system is performing excellent. Cv(HMP) was evidently affected most by hydraulic and manufacture variation. The overall Cv(HMP) is maximum in Charsadda plot No.2 is 16.1%  while in plot No.3 and 4 this range from 1.8 to 0.6%. In Malakand and Nowshera farm this overall variation give negative values due to more variation in the level of plugging and CV(HM). .

Performance Assessment of Existing Drips Irrigation Systems’ Parameters (Uniformity, Efficiency and Adequacy Degree Installed In Selected Sites of Peshawar Valley

The study was conducted to assess the performance of drip irrigation systems installed at Charsadda, Malakand Agency and Nowshera. The performance parameters of the drip irrigation system included the coefficient of variation of emitters flow rate with respect to uniformity, efficiency, adequacy and estimated design discharge by Dadex were compared with physical need based CROPWAT software estimation were evaluated. The emission uniformity in Charsadda farm range from 99.1 to 99.7%. In Malakand Agency farm it range between 96.1 to 97.9% while in Nowshera it range from 86.1 to 100%. Statistical uniformity calculated in Charsadda farm range from 99.3-99.8%. In Malakand Agency it is between 96 –97.3% and 82.8 to 100% in Nowshera farm. Application efficiency of drip system in Charsadda farm is between 88 to 100%. In Malakand it ranges from 67 to 83% while in Nowshera farm it is from 36 to 62%. The storage efficiency is maximum (80.3%) in Malakand Agency farm and minimum in Nowshera farm (24.9%). Charsadda farm has 62.5% average storage efficiency. Adequacy of irrigation having full irrigation of 2.4cm which is he desired depth of application. The adequacy of irrigation for the field in figure 21 is 52.5 percent, since 52.5 percent of the field receives the desired depth of application or more.
