RESUMO

Borophene nanosheets appear in various sizes and shapes, ranging from simple planar structures to complicated polyhedral formations. Due to their unique chemical, optical, and electrical properties, Borophene nanosheets are theoretically and practically attractive and because of their high thermal conductivity, boron nanosheets are suitable for efficient heat transmission applications. In this paper, temperature indices of borophene nanosheets are computed and these indices are employed in QSPR analysis of attributes like Young's modulus, Shear modulus, and Poisson's ratio of borophene nanosheets and borophene ß12 sheets. The regression model for the F-Temperature index is discovered to be the best fit for shear modulus, the reciprocal product connectivity temperature index is discovered to be fit for Poisson's ratio and the second hyper temperature index is discovered to be fit for Young's modulus based on the correlation coefficient.

RESUMO

In the present study, we aimed to synthesize (Ag)1-x(GNPs)x nanocomposites in variable ratios (25% GNPs-Ag, 50% GNPs-Ag, and 75% GNPs-Ag) via an ex situ approach to investigate the incremental effects of GNPs (graphene nanoparticles) on AgNPs (silver nanoparticles). The prepared nanocomposites were successfully characterized using different microscopic and spectroscopic techniques, including X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, ultraviolet spectroscopy, and Raman spectroscopic analysis. For the evaluation of morphological aspects, shape, and percentage elemental composition, SEM and EDX analyses were employed. The bioactivities of the synthesized nanocomposites were briefly investigated. The antifungal activity of (Ag)1-x(GNPs)x nanocomposites was reported to be 25% for AgNPs and 66.25% using 50% GNPs-Ag against Alternaria alternata. The synthesized nanocomposites were further evaluated for cytotoxic potential against U87 cancer cell lines with improved results (for pure AgNPs IC50: ~150 µg/mL, for 50% GNPs-Ag IC50: ~12.5 µg/mL). The photocatalytic properties of the nanocomposites were determined against the toxic dye Congo red, and the percentage degradation was recorded as 38.35% for AgNPs and 98.7% for 50% GNPs-Ag. Hence, from the results, it is concluded that silver nanoparticles with carbon derivatives (graphene) have strong anticancer and antifungal properties. Dye degradation strongly confirmed the photocatalytic potential of Ag-graphene nanocomposites in the removal of toxicity present in organic water pollutants.

RESUMO

BACKGROUND: Prone positioning improves ventilation-perfusion mismatch, distribution of gravitational gradient in pleural pressure, and oxygen saturation significantly in patients with Covid pneumonia. We aimed to find out the efficacy of eight hours per day of intermittent selfprone positioning for seven days in patients affected with COVID-19 pneumonia/ ARDS. METHODS: This Randomized Clinical Trial was conducted in the Covid isolation wards of Ayub Teaching Hospital, Abbottabad. Patients suffering from COVID-19 pneumonia/ ARDS were enrolled with permuted block randomization into a control and an experimental group each consisting of 36 patients. Parameters of Pneumonia Severity Index (PSI) score along with other sociodemographic data was noted on a preformed structured questionnaire. Death was confirmed by requesting the death certificate of patients on the 90th day of enrolment. Data Analysis was done with SPSS Version 25. Tests of significance were applied to calculate the difference in the patients of the two groups with respect to respiratory physiology and survival. RESULTS: The mean age of the patients was 63.79±15.26 years. A total of 25 (32.9%) male and 47 (61.8%) female patients were enrolled. Statistically significant improvement was found in the respiratory physiology of the patients at 7th and 14th DOA between the groups. Pearson Chi-Square test of significance showed a difference in mortality between the two groups at 14th DOA (pvalue=0.011) but not at 90th DOA (p-value=0.478). Log Rank (Mantel-Cox) test of significance, applied on the Kaplan Meier curve and showed no statistically significant difference among the groups based on the survival of the patients. (p-value=0.349). CONCLUSIONS: Early transient improvement in respiratory physiology and mortality does occur with 8 hours of self-prone positioning for seven days but there is no effect on the 90-day survival of the patients. Thus, the impact of the manoeuvre on improving survival needs to be explored with studies having an application of the manoeuvre for a longer duration and period.

RESUMO

BACKGROUND: The coronavirus 2019 (COVID-19) pandemic had a major impact on the educational institutes globally and resulted in the transition from traditional educational systems to online electronic learning methods. OBJECTIVE: This study endeavored to address and compare the dental student's understanding regarding the Oral Biology course by assessing their knowledge and skills between the students enrolled during 2020 (online teaching) and 2021 (face-to-face teaching). This study also aimed to assess the perception of dental students regarding the virtual mode of teaching. METHODS: This quasi-experimental study evaluated students from two years, in which a retrospective group of dental students enrolled during the academic year 2020 were compared with a prospective experimental group enrolled during the academic year 2021. Knowledge and skills for both years were compared. This comprised of theoretical and practical component. Students also completed a questionnaire that assessed student's perception regarding online teaching. RESULTS: A total of 98 students of Bahria University Dental College participated. A comparison between grade scores of online and traditional learning groups reported statistically significant differences (p = 0.05*) with regards to short answer question types, viva or verbal questions (p = 0.016*). Strong correlations were observed via the multivariable analysis. All correlations were statistically significant at p < 0.01 level. Learning satisfaction was not satisfactorily observed by the online learning group. CONCLUSION: It can be concluded that despite the disruption that the educational sector had to face due to the COVID-19 pandemic, based on the differences in the subjective domain scores, students appeared to like on-campus teaching more than the online teaching, as most students found online learning to be stressful and were quite unsatisfied. However, the difference in mode of teaching did not affect the knowledge and skills of the dental students.

RESUMO

The most common cause of infertility and metabolic problems among women of reproductive age is polycystic ovary syndrome (PCOS), a multifaceted disorder. It is an endocrine disorder that occurs in approximately one in seven women. Among these PCOS patients, two thirds will not ovulate on a regular basis and seek treatment for ovulation induction. The symptoms vary in their severity, namely ovulation disorders, excessive androgen levels, or polycystic ovarian morphology. All these symptoms require a therapeutic approach. Many drugs are used to eradicate PCOS symptoms, like metformin, clomiphene citrate, spironolactone, and pioglitazone. Long-term treatment is required to achieve the desired outcome, which is often accompanied by significant adverse reactions. Some herbs and phytochemicals are equally effective for treating PCOS and produce minimal side effects. Recently, herbal products are gaining popularity due to their wide biological activities, safety, availability, and efficacy. The present review covers aetiology, current treatment, pathophysiology, and detailed pre-clinical and clinical studies on plants and phytochemicals that are proven to be useful for the treatment of symptoms associated with PCOS.

RESUMO

Microbial pathogens and bulk amounts of industrial toxic wastes in water are an alarming situation to humans and a continuous threat to aquatic life. In this study, multifunctional silver and graphene nanocomposites (Ag)1-x(GNPs)x [25% (x = 0.25), 50% (x = 0.50) and 75% (x = 0.75) of GNPs] were synthesized via ex situ approach. Further, the synthesized nanocomposites were explored for their physicochemical characteristics, such as vibrational modes (Raman spectroscopic analysis), optical properties (UV visible spectroscopic analysis), antibacterial and photocatalytic applications. We investigated the antimicrobial activity of silver and graphene nanocomposites (Ag-GNPs), and the results showed that Ag-GNPs nanocomposites exhibit remarkably improved antimicrobial activity (28.78% (E. coli), 31.34% (S. aureus) and 30.31% (P. aeruginosa) growth inhibition, which might be due to increase in surface area of silver nanoparticles (AgNPs)). Furthermore, we investigated the photocatalytic activity of silver (AgNPs) and graphene (GNPs) nanocomposites in varying ratios. Interestingly, the Ag-GNPs nanocomposites show improved photocatalytic activity (78.55% degradation) as compared to AgNPs (54.35%), which can be an effective candidate for removing the toxicity of dyes. Hence, it is emphatically concluded that Ag-GNPs hold very active behavior towards the decolorization of dyes and could be a potential candidate for the treatment of wastewater and possible pathogenic control over microbes. In the future, we also recommend different other in vitro biological and environmental applications of silver and graphene nanocomposites.

RESUMO

An accurate therapeutic diet can help people improve their medical condition. Any discrepancy in this regard could jeopardize a patient's clinical condition. This study was aimed to determine prevalence of dietary errors among in-patients at an international private hospital's food department, and to explore causes of error to suggest strategies to reduce such errors in the future. Thus, a sequential explanatory mixed-methods study was carried out. For the quantitative part, secondary data were collected on a daily basis over one-month. For qualitative data, errors arising during the meal flow process were traced to the source on the same day of error followed by qualitative interviews with person responsible. Quantitative data were analyzed in SPSS v.25 as percentages. Qualitative data were analyzed by deductive-inductive thematic analysis. Out of a total of 7041 diets, we found that only 17 had errors. Of these, almost two-thirds were critical. Majority of these errors took place during diet card preparation (52.94%), by dietitians (70.59%), during weekdays (82.35%), breakfasts (47.06%), and in the cardiac care ward (47.06%). The causes identified through interviews were lack of backup or accessory food staff, and employee's personal and domestic issues. It was concluded that even though the prevalence of dietary errors was low in this study, critical errors formed majority of these errors. Adopting organizational behavior strategies in the hospital may not only reduce dietary errors, but improve patients' well-being, and employee satisfaction in a long run.

RESUMO

The recent monsoon rains in Pakistan were unprecedented and caused flooding all over Pakistan, especially in Sindh and Balochistan. Following this national disaster, various water-borne and contagious diseases started erupting all over the country. In such a calamity-struck city of Jacobabad, we started receiving cases with a peculiar set of ocular complaints mimicking viral keratoconjunctivitis. Failure to respond to traditional treatment and the unique appearance of these corneal opacities led to a rare diagnosis of Microsporidial Keratoconjunctivitis, which was later confirmed by microscopy and staining of corneal scrapings of the most affected case. In line with published literature, all cases were treated with topical fluoroquinolone and topical anti-fungal therapy, following which the disease was cleared within a week. The disease has seen an upward trend the world over, especially among Asia. To the best of our knowledge, no such cases have been reported in Pakistan as yet. In this case series, we highlight the strong correlation of emergence of microsporidial keratitis in patients following exposure to pooled water bodies after the monsoon rainy season and floods. Moreover, this report will help create awareness in eye professionals regarding the prevention, timely diagnosis and treatment of these rare and emerging cases. Key Words: Keratitis, Spores, Water-borne diseases, Microsporidia.

RESUMO

BACKGROUND: The Social Health Protection Initiative (SHPI) was introduced initially in Pakistan in Khyber Pakhtunkhwa Province. The initiative aimed to provide the lowest socioeconomic group of the population with in-patient healthcare services, which otherwise would be financially hard to obtain. It is one of the flagship projects of the Provincial Government to contribute towards the United Nations Sustainable Development Goals and universal health coverage. AIMS: To assess consumer choice of health facility and its determinants for public versus private sector health facilities by people enrolled in SHPI. METHODS: We used secondary data of availed health services from February 2016 to September 2017 under SHPI. A proxy outcome variable, visit to health facility, was used to determine consumer choice between public and private sector health facilities. The treatment group (health services received by beneficiaries) was used as an independent variable controlled for age groups, cost groups, and geographic location of health facilities. All statistical analyses were performed by SPSS version 20. RESULTS: Most beneficiaries chose private over public health facilities (90.25%). The adjusted odds of visiting a public sector health facility for surgical and obstetrics/gynaecological services were 0.12 [95% confidence interval (CI): 0.10-0.16] and 0.11 (95% CI: 0.09-0.14) respectively, when compared to medical services. CONCLUSION: SHPI beneficiaries have lesser odds of visiting a public hospital over a private one. The choice may be affected by factors such as age of the beneficiary, cost of health services, and geographic location of health facilities.

RESUMO

BACKGROUND: Many factors have been identified which can predict severe outcomes and mortality in hospitalized patients of COVID-19. This study was conducted with the objective of finding out the association of various clinical and laboratory parameters as used by International Severe Acute Respiratory and emerging Infections Consortium (ISARIC) World Health Organization (WHO)- ISARIC/WHO 4C Mortality score in predicting high risk patients of COVID-19. Ascertaining the parameters would help in triage of patients of severe disease at the outset, and shall prove beneficial in improving the standard of care. METHODS: This cross-sectional study was carried out in COVID-19 Department of Ayub Teaching Hospital, Abbottabad. All COVID-19 patients admitted from 15th April to 15th July 2020 were included. RESULTS: A total of 347 patients were included in the study. The mean age was 56.46±15.44 years. Male patients were 225 (65%) and female 122 (35%). Diabetes (36%) was the most common co-morbidity, followed by hypertension (30.8%). Two hundred & six (63.8%) patients recovered and 117 (36.2%) patients died. Shortness of breath (80%), fever (79%) and cough (65%) were the most common presenting symptoms. Patients admitted with a 4C Mortality score of 0-3 (Low Risk Category), the patients who recovered were 36 (90%) and those who died were 4 (10.0%). In patients admitted with a 4C Mortality score of more than 14 (Very High-Risk Category), the number of patients who recovered was 1 (20%), and those who died were 4 (80%). The difference in mortality among the categories was statistically significant (p<0.001). Hypertension was a risk factor for death in patients of COVID-19 (Odds ratio=1.24, 95% CI [0.76-2.01]). Lymphopenia was not associated with statistically significant increased risk for mortality. CONCLUSIONS: The ISARIC 4C mortality score can be used for stratifying and predicting mortality in COVID-19 patients on arrival in hospital. We propose that it should be used in every patient of COVID-19 presenting to the hospital. Those falling in Low and Intermediate Risk Category should be managed in ward level. Those falling in High and Very High Category should be admitted in HDU/ICU with aggressive treatment from the start.

RESUMO

Objective To determine the efficacy of 5-Fluorouracil (FU) in the treatment of pterygium. Methodology After meeting the inclusion criteria 101 patients were enrolled in this study. Informed consent and demographic information was taken from all the patients. Patients underwent ophthalmic clinical examination that included slit lamp examination to grade pterygium. Before starting 5-FU injections, all topical medication was stopped. After four weeks the effects of 5-FU and its efficacy was noted. The patients were reviewed again after six months to note any recurrence. All the collected data was entered and analyzed on Statistical Package for Social Sciences (SPSS) version 20 (IBM Corp., Armonk, NY). Results In our study the mean age of the patients was 37.74 ± 10.15 years, male to female ratio of the patients was 1.06:1. The primary type of pterygium was noted in 54 (53.5%) and recurrent was noted in 47 (46.5%) patients. The efficacy achieved in 88 (87.13%) patients, four had recurrence of pterygium and of 101 patients 26 underwent surgical excision. Conclusion The use of 5-FU is safe and effective for the treatment of pterygium and it can be implemented as a primary treatment especially in the hot temperate zone where it is very common and aggressive with high recurrence rate. 5-FU not only halts its progression but also reduces the size and vascularity thus decreasing the need for surgery and steroid use and preventing recurrence.

RESUMO

OBJECTIVE: To determine the role of hypertension, hyperlipidemia, smoking and positive family history of diabetes and hypertension in the development of diabetic retinopathy. METHODS: This prospective cohort study was conducted at the Department of Chemical Pathology, Armed Forces Institute of Pathology, Rawalpindi over 2 years period from June 2014 to June 2016. One hundred consecutive diabetic patients with no signs of diabetic retinopathy and good glycemic control (HbA1c<6.5%) were registered by non-probability convenient sampling after taking written informed consent. They were evaluated for hypertension, hyperlipidemia and smoking status. These patients were then followed 6 monthly for 2 years to look for the development of diabetic retinopathy. RESULTS: The mean age of the patients was 50.72±9.29 years and there were 57 (57%) male and 43 (43%) female patients. Majority (82%) of the patients had NIDDM. The mean duration of diabetes was 8.31±6.83 years. 11% of the patients were smoker, 37% were hypertensive, 6% had hyperlipidaemia, 62% had family history of diabetes and 30% had family history of hypertension. At the end of follow-up, 9 (9.0%) patients had diabetic retinopathy. The frequency of diabetic retinopathy increased with increasing age of the patient; however, the difference was statistically insignificant. A comparatively higher frequency of diabetic retinopathy was also seen in patients with IDDM and those with positive family history of diabetes and hypertension yet again, the difference was statistically insignificant. Also, no significant difference was noted among male and female genders and smokers vs. non-smoker. However, the frequency of diabetic retinopathy increased significantly with increasing duration of diabetes. It was also higher among those with hypertension and hyperlipidemia. CONCLUSION: Higher patient age (≥50 years), increasing duration of diabetes (≥20 years), insulin dependent diabetes mellitus, hypertension, hyperlipidemia, and positive family history of diabetes and hypertension were found to be associated with increased frequency of diabetic retinopathy.

RESUMO

The importance of childhood immunization in prevention of highly fatal diseases and disability cannot be overemphasized. Pakistan has a national Expanded Program on Immunization but the compliance is far below the international benchmark for achieving a herd immunity. Monitoring the compliance to timely receipt of vaccinations is crucial to establishing and preventing disease and disability associated risk in children. There is little or no evidence that reports the timeliness of the vaccinations according to the EPI schedule in Peshawar. The primary objective of the study was to evaluate rate of Fully Immunized Children and to report compliance to the timeliness of vaccine specific schedule during the study period in the EPI center in the capital city of Peshawar, Khyber Pakhtunkhwa province of Pakistan. We collected consecutive retrospective data of the infants enrolled from June 2014 to December 2015 in one EPI center for our study. Out of the total 157 (n) children, fully immunized children (FIC) were 62 (39.5%) and only 19 (12.1%) were FIC with timely visits. Dropouts increased with successive vaccinations with highest for Measles 1 (42%). On-time vaccinations decreased over time, while the proportion of children receiving vaccination outside the ideal window period reaches as high as 46%. The study reports a low compliance to EPI schedule, and also highlights that immunization coverage is not a good indicator of age appropriate vaccinations.

RESUMO

BACKGROUND: Cancer is considered one of the most predominant causes of morbidity and mortality all over the world and colorectal cancer is the most common fatal cancers, triggering the second cancer related death. Despite progress in understanding carcinogenesis and development in chemotherapeutics, there is an essential need to search for improved treatment. More than the half a century, cytotoxic and cytostatic agents have been examined as a potential treatment of cancer, among these agents; remarkable progresses have been reported by the use of the snake venom. Snake venoms are secreting materials of lethal snakes are store in venomous glands. Venoms are composite combinations of various protein, peptides, enzymes, toxins and non proteinaceous secretions. CONCLUSION: Snake venom possesses immense valuable mixtures of proteins and enzymes. Venoms have potential to combat with the cancerous cells and produce positive effect. Besides the toxicological effects of venoms, several proteins of snake venom e.g. disintegrins, phospholipases A2, metalloproteinases, and L-amino acid oxidases and peptides e.g. bradykinin potentiators, natriuretic, and analgesic peptides have shown potential as pharmaceutical agents, including areas of diagnosis and cancer treatment. In this review we have discussed recent remarkable research that has involved the dynamic snake venoms compounds, having anticancer bustle especially in case of colorectal cancer.

RESUMO

OBJECTIVE: To determine the visual outcome and its prognostic factors in patients presenting with ocular war injuries. METHODS: This descriptive, observational study was conducted at the Combined Military Hospital, Peshawar, Pakistan, from June 2012 to March 2016, and comprised soldiers with ocular war injuries. Informed consent was obtained from all participants. A predesigned proforma was used to record patient's demographic details along with the cause, side, type and severity of injury. Injuries were classified as open globe or closed globe injuries. Ocular trauma score grade was used to describe the severity of injury. RESULTS: There were 210 participants with an overall mean age of 29.34±5.35 years (range: 20-43 years). All of them were male. Left side was more frequently involved, i.e. in 126(60%) cases. The most frequent underlying cause was improvised explosive device blast injury 114(54.3%), followed by blunt trauma 42(20%) and road traffic accidents 24(11.4%). Closed globe injuries were more frequent and were recorded in 120(57.1%) patients. The visual outcome was good in 62(29.5%) patients, followed by fair in 51(24.3%) patients while 51(24.3%) patients had worst visual outcome. When stratified, there was no significant difference of worst visual outcome with patient's age (p=0.279). However, improvised explosive device blast (p=0.002), open globe injury (p=0.000), ocular trauma score grade 1; open globe (p=0.049), closed globe (p=0.003) were associated with significantly higher frequency of worst visual outcome. Zone-III injury was also prognostic of worst visual outcome, but the difference was significant only in case of open globe injury (p=0.003). CONCLUSIONS: Improvised explosive device blast, open globe injury and ocular trauma score grade 1 were poor prognostic features and resulted in significantly higher frequency of poor visual outcome.

RESUMO

OBJECTIVE: To determine the Efficacy of Corneal Crosslinkage (CXL), using Corneal Topography, in eyes with progressive Keratoconus. METHODS: This randomized control trial was conducted at Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from October 2013 to April 2014. A total of 60 eyes of 30 patients were included who presented with bilateral progressive Keratoconus. Each eye of the patient was randomized either to a treatment group (Group-A) or control untreated group (Group-B) of 30 eyes each. A written informed consent was obtained from each patient, following which corneal crosslinkage (CXL) with topical riboflavin eye drops was performed. Follow up visit was done at three months post operatively, Corneal topography was repeated and recorded. RESULTS: The mean age of the patients was 23.13±7.62 years (range 13 to 39 years). There were 26 males and 34 females patients. The mean simK value at the start of study was 50.94±4.84 diopters in Group-A and 49.73±5.24 diopters in Group-B. At three months follow-up, the mean simK value was significantly lower in Group-A (48.28±4.47) as compared to Group-B (51.11±4.85). Keratoconus improved/ remained stable in 34 (56.7%) eyes while progressive disease was noted in 26 (43.3%) eyes. When compared between the groups, the frequency of efficacy was significantly higher in Group-A (86.7% vs. 26.7%; p=.000) as compared to Group-B. CONCLUSION: Corneal Crosslinking was found effective in causing regression or halting the progression of disease in patients with progressive Keratoconus at three months follow-up, however, the efficacy of corneal crosslinking was unaffected by patient's age and gender.

RESUMO

Retinal artery occlusion is an uncommon condition but can lead to grave consequences if not managed in time. Elderly population with other comorbid conditions like hypertension, ischemic heart disease, hyperlipidemia and stroke are commonly affected. However, this condition may affect younger population with entirely different systemic associations. Thromboembolism, which usually takes place secondary to cardiac emboli or hypercoagulable states cause retinal artery occlusion in young population. A24-year lady presented with a short history of unilateral altitudinal visual loss. On examination, she was found to have hemiretinal artery occlusion. Ocular massage, anterior chamber paracentesis was performed initially, followed by Nd YAG laser embolysis, which led to successful restoration of retinal circulation and significant improvement in visual field loss. Detailed evaluation and systemic investigations were carried out to identify the underlying cause, but no systemic association could be found.

RESUMO

OBJECTIVE: To compare the mean change in corneal astigmatism and clinical appearance after intralesional injection of 5-Fluorouracil in primary and recurrent pterygia. METHODS: The quasi-experimental study was conducted at the Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan, from June 2014 to April 2015. The patients were categorised into two groups. Group1 named GP comprised primary pterygia patients, while those of recurrent pterygia were in Group 2 named GR. All the patients were treated with 0.1ml intralesional 5-Fluorouracil 5mg weekly injections for 04 weeks. Ophthalmic clinical evaluation included uncorrected distant visual acuity, keratometery and slit lamp examination was performed before and 04 weeks after the treatment. RESULTS: There were 86 eyes of 64 patients in the study. Mean uncorrected distant visual acuity of patients was 0.12±0.13 in GP and 0.26±0.17 in GR. Mean astigmatism before treatment was 1.75±1.08 in GP and 2.92±2.28 in GR. Same parameters 04 weeks after last injection were 1.66±1.17 and 2.64±1.78 in GP and GR respectively. All eyes had a statistically significant change in clinical appearance. CONCLUSIONS: Intralesional 5-Fluorouracil injection improved cosmesis of primary as well as recurrent pterygia, but did not have statistically significant effect on corneal astigmatism.

RESUMO

OBJECTIVE: To determine mean change in visual acuity, corneal astigmatism and clinical appearance of pterygium after intralesional injection of 5-Fluorouracil. METHODS: This was a Quasi experimental study conducted at Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from June 2014 to May 2015. Total 68 eyes of 54 patients were included in the study. Patients were treated by injecting 0.1 ml of 5-FU (5mg) weekly injections for 04 weeks. All the patients underwent ophthalmic clinical examination that included Uncorrected distant visual acuity (UCVA), corrected distant visual acuity (CDVA), keratometery with Auto Ref-keratometer (RK-F1, Canon) and slit lamp examination before and 04 weeks after the last injection. RESULTS: Total 68 eyes of 54 patients (18 females and 36 males) were treated with intralesional injection of 5 FU. Out of total, 30 were right eyes while 38 were left eyes. Age of patients ranged from 23 to 53 years with mean age of 39.2 ± 4.90 years. Mean UCVA and corneal astigmatism before treatment were 0.162 ± 0.167 and 2.12 ± 1.53 respectively while the same parameters 04 weeks after last injection of 5 FU were 0.166 ± 0.168 and 1.92±1.45 respectively. The magnitude of induced change in astigmatism was (0.235 ± 1.35). Ninety seven percent of the patients showed improvement in clinical appearance. CONCLUSION: Intralesional 5-FU injection results in significant clinical and cosmetic improvement of primary pterygium.

RESUMO

OBJECTIVE: To determine the etiology and severity of various forms of ocular war injuries in patients presenting at an Army Hospital in Pakistan. METHODS: This cross sectional study was conducted at the Department of Ophthalmology, Combined Military Hospital, Peshawar over four years period from June 2012 through March 2016, Two hundred ten consecutive soldiers who presented with ocular war injuries were included for analysis after taking written informed consent. A predesigned proforma was used to record patient's demographic details along with the cause, side, type and severity of injury, ocular trauma score was also recorded at presentation. RESULTS: The mean age of the patients was 29.34±5.35 years. All of them were males. Left side was more frequently involved (n=126, 60.0%) and the most frequent underlying cause was IED blast injury (n=114, 54.3%). Closed globe injuries were more frequent and were recorded in 120 (57.1%) patients. Upon assigning Ocular Trauma Score, Grade-V (28.6%) injuries were the most frequent followed by Grade-I (25.7%), Grade III (25.7%), Grade II (11.4%) and Grade IV (8.6%). When stratified for the type of injury, OTS Grade I injuries were highest (60.0%) among patients with open globe injuries, hence poorer prognosis, while OTS Grade V injuries were highest (50.0%) among patients with closed globe injuries (p=0.000). CONCLUSION: IED blast injuries are most frequently encountered ocular war injuries often involving soldiers in the age group 20-30 years. These open globe injuries had worst clinical presentation to begin with and poorer prognosis than closed globe injuries.
