Abstract
Abstract Zinc oxide nanoparticles were synthesized from the leaf extract of Brassica oleracea L. Acephala group (collard green) followed by their characterization using Scanning Electron Microscope (SEM), and Energy Dispersive X-ray (EDX). The antibacterial properties of zinc nanoparticles were tested against Gram-negative bacteria, Pseudomonas aeruginosa (ATCC ® 9027™), Escherichia coli (ATCC ® 8739™), Klebsiella pneumoniae (ATCC® BAA-1705™) and Gram-positive bacteria, Staphylococcus aureus (ATCC ® 6538™) and Listeria monocytogenes (ATCC ® 13932™), at four different concentrations (50.00 µg/ml, 100.00 µg/ml, 500.00 µg/ml and 1 mg/ml) of zinc oxide nanoparticles suspension. Results revealed that the synthesized nanoparticles exhibit strong antibacterial effects against Pseudomonas aeruginosa, Listeria monocytogenes, Klebsiella pneumonia, Staphylococcus aureus and Escherichia coli at 500.00 µg/ml-1 mg/ml concentrations. An increase in efficacy of nanoparticles with the decrease of their size was also evident. This is a first ever report on Brassica oleracea, L. based nanoparticles which demonstrates that 500.00 µg-1 mg/ml conc. of zinc oxide nanoparticles have antibacterial activity against both Gram -ve and Gram +ve bacteria and have the potential to be considered as an antibacterial agent in future.

Abstract
Abstract Due to extensive application of antibiotics as growth promoters in animal feed, antimicrobial resistance has been increased. To overcome this challenge, rumen microbiologists search for new probiotics to improve the rate of livestock production. The present study was aimed to isolate and evaluate breed-specific lactic acid bacteria (LAB) as potential animal probiotics. The current study was conducted during 10 months from July 2020 to April 2021, in which a total of n=12 strains were isolated from different samples including milk, rumen, and feces of Nilli Ravi Buffaloes. These isolates were evaluated for their antimicrobial potential against common animal pathogens (Bacillus spp., E. coli, Staphylococcus aureus, Salmonella spp., Listeria spp.). All the isolates were identified using 16S rRNA gene sequencing and the phylogenetic analyses inferred that these strains showed close relations to the species of various genera; Enterococcus lactis, Pediococcus pentosaceus, Bacillus subtilis Weissella cibaria, Weissella soli, Bacillus tequilensis, Weissella bombi, Bacillus licheniformis, Lactococcus lactis, Bacillus megaterium, Lactobacillus ruminis, and Lactococcus lactis. NMCC-Ru2 has exhibited the enormous potential of antimicrobial activity, 28 mm, for Salmonella typhimurium;23 mm for Listeria monocytogenes 21 mm for E.coil. Highest resistance was seen in NMCC-Ru2 agasint test antbiotic, like 25.5 mm for Tetracycline. Overall results revesl that the probiotic profile of isolates was achieved using standard criteria, particularly with animal probiotic properties

Abstract
The present study was conducted to explore the ethnomedicinal uses, quantitative analysis and conservation status of medicinal flora of Sultan Khail valley, Dir Upper, Pakistan. The data was collected during 2017-2019 using a semi-structured questionnaire. Ethnomedicinal uses of plant species were determined and the plant species were classified based on habits, parts used, and method of preparation of remedies. Frequency of citation (FC), relative frequency of citation (RFC) and family importance values (FIV) were calculated. The plant species were assessed for their conservation status as per IUCN standard criteria. The inhabitants of the Sultan Khail valley use 88 plant species belonging to 57 families for the treatment of different human diseases. Lamiaceae was the dominant family represented with 8 medicinal species (9%) followed by Rosaceae (5 species, 6%). The most commonly used plant parts were leaves (33.1%) followed by fruits (16.1%), while the main method of remedy preparation was decoctions (33.3%). The highest RFC value was recorded for Geranium wallichianum (0.47), followed by Berberis lycium (0.44). Lamiaceae was the most cited family (FIV, 231), followed by Polygonaceae (73). Five plant species were found to be endangered, 39 species were vulnerable, 32 species were rare, and 12 species were found to be infrequent. The medicinal flora of the area is under severe biotic pressure and needs proper conservation; otherwise, they will be lost in the near future.

Abstract
BACKGROUND Spinal anaesthesia, the most common form of anaesthesia for caesarean section, leads to sympathetic blockade and profound maternal hypotension resulting in adverse maternal and neonatal outcomes. Hypotension, nausea and vomiting remain common but until the publication of the National Institute of Health and Care Excellence (NICE) 2021 guidance, no national guideline existed on how best to manage maternal hypotension following spinal anaesthesia for caesarean section. A 2017 international consensus statement recommended prophylactic vasopressor administration to maintain a systolic blood pressure of >90% of an accurate pre-spinal value, and to avoid a drop to <80% of this value. This survey aimed to assess regional adherence to these recommendations, the presence of local guidelines for management of hypotension during caesarean section under spinal anaesthesia, and the individual clinician's treatment thresholds for maternal hypotension and tachycardia. METHODS The West Midlands Trainee-led Research in Anaesthesia and Intensive Care Network co-ordinated surveys of obstetric anaesthetic departments and consultant obstetric anaesthetists across 11 National Health Service Trusts in the Midlands, England. RESULTS One-hundred-and-two consultant obstetric anaesthetists returned the survey and 73% of sites had a policy for vasopressor use; 91% used phenylephrine as the first-line drug but a wide range of recommended delivery methods was noted and target blood pressure was only listed in 50% of policies. Significant variation existed in both vasopressor delivery methods and target blood pressures. CONCLUSIONS Although NICE has since recommended prophylactic phenylephrine infusion and a target blood pressure, the previous international consensus statement was not adhered to routinely.

Abstract
Introduction
Poor muscle health is associated with a series of chronic and metabolic conditions that are prevalent in individuals who chronically experience poor-quality sleep. But there is no study deciphering the role of sleep deprivation on muscle ageing. Therefore, in the present study we have measured the ultrastructure, histopathology, and oxidative stressors in soleus muscle of wistar rat after sleep deprivation and recovery sleep.
Material and Methods
The experiments were conducted in 18 rats of three groups. Group I rats had normal sleep wake cycle, Group II rats were subjected to 24 h sleep deprivation (SD) by gentle handling method1 and Group III rats had recovery sleep after 24 h SD. At the end of the sleep, sleep deprivation and recovery period, soleus muscle tissue was collected for ultrastructural, histological and oxidative stress markers. Oxidative damage was assessed by lipid peroxidation, catalase activity, reduced glutathione and nuclear labelling of 8-OHdG. The study was conducted as per the guidelines of the Institutional Animal Ethics Committee (960/IAEC/16).
Results
The data demonstrated that SD leads to ultrastructural changes in soleus muscle which includes sarcolemmal and mitochondrial alterations. In case of histopathological and histomorphological changes there was signs of tissue degeneration, inflammatory infiltrate in type I fibres and muscle atrophy was observed in soleus muscles. There was significant increase in level of 8-OHdG (p=0.02) and malondialdehyde in 24h SD (p=0.02) than control and recovery sleep groups. Moreover, the catalase activity and reduced glutathione level was significantly decreased in 24h SD group (p≤0.02) than control and recovery sleep.
Conclusion
24hr sleep deprivation leads to an ageing like state in the skeletal muscle, which was recovered after sleep rebound.

Abstract
Pregnancy in women with systemic lupus erythematosus (SLE) is associated with an increased risk of adverse maternal and fetal outcomes. Risk is significantly increased when SLE pregnancy is complicated by anti-phospholipid syndrome (APS). Here, we present a case of a 21 year-old multi-gravid lady with SLE- associated APS who was diagnosed as such when she presented with multisystem flare at her 16 weeks of gestation. At presentation she had fever, multiple joint pain in both upper and lower limbs, loss of hair, history of recurrent oral ulcer, skin rash over hand and feet. Physical examination and laboratory evaluation were consistent with an active SLE flare. A diagnosis of antiphospholipid syndrome (APS) was made based on her clinical presentation and laboratory findings. The reported patient had APS secondary to SLE. She had all the risk factors that would confer a remarkably high risk of pregnancy morbidity: positive anti-SSA(RO) antibody and lupus anticoagulant, history of one neonatal death due to congenital heart block and two consecutive first trimester pregnancy loss. Multidisciplinary management approach with appropriate intervention and close monitoring can bring a successful outcome.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Results: Different morphological pattern includes papillary (8/18, 44%), nested (2/18, 11.1%), alveolar (3/18, 16.7%), nested and papillary (3/18, 16.7%), solid and nested (1/18, 5.6%), cystic and nested (1/18, 5.6%). Four cases show papillary architecture with a linear array of nuclei away from the basement membrane, a pattern seen in SFPQ-TFE3 renal cell carcinoma and NONO-TFE3 renal cell carcinoma. Strong nuclear TFE3 expression was seen in 9/18 (50%) cases. Cathepsin k expression was seen in 6/11 (54%) cases, Ck7 was focal weak positive in 4/12 (25%) cases, PAX8 was positive in 8/8 (100%) cases, and CA IX was focal weak positive in 1/5 (20%) case. According to follow-up data, disease progression was seen in only one case with the low-stage disease. No death was reported due to renal cell carcinoma to date of follow-up.
Conclusion: We have suggested that young patient age, unusual morphological features and an immunohistochemical panel may help reach the diagnosis in countries with limited resources.

Abstract
The presence of pathogenic bacteria in food is considered as a primary cause of food-borne illness and food quality deterioration worldwide. The present study aimed to determine the effectiveness of five essential oils (EOs) against multidrug-resistant foodborne pathogens. In the current study Gram-negative bacteria (Escherichia, Enterobacter, Citrobacter, Proteus, Pseudomonas, and Klebsiella) and the Gram-positive bacteria Staphylococcus were isolated from raw milk and biochemically characterized. The anti-bacterial effect of different antibiotics and EOs (thyme, oregano, lemongrass, mint, and rosemary) was determined using the standard disc diffusion method. The antibiogram study revealed that Gram-negative bacteria were highly resistant to penicillin while Staphylococcus was resistant to streptomycin, amoxicillin, and lincomycin. Moderate resistance was observed to doxycycline, amikacin, enrofloxacin, kanamycin and cefixime. Isolates were found less resistant to gentamycin, chloramphenicol, and ciprofloxacin. EOs showed a broad range of antimicrobial activity against all bacteria except P. aeruginosa. Of these, thyme was more effective against most of the multi-drug resistant bacterial strains and formed the largest zone of inhibition (26 mm) against Escherichia followed by oregano oil (18 mm) against Staphylococcus (p<0.05). Klebsiella spp and Citrobacter spp showed resistance to mint and lemongrass oil respectively. The EOs such as lemongrass, mint and rosemary were less active against all the bacteria. The findings of the recent study suggest the use of EOs as natural antibacterial agents for food preservation.

Abstract
OBJECTIVES The consensus conference of the International Society of Urological Pathology (ISUP), held in 2012, made recommendations regarding prognostic parameters of renal tumors. There was a strong consensus that tumor morphotype, pathologic tumor stage, and tumor grade are prognostic indicators of poor outcome. It was also agreed upon that prognostic significance of tumor necrosis is in evolution, and both microscopic and macroscopic tumor necrosis should be documented in percentages. The aim of our study was to explore the impact of tumor necrosis on metastasis-free survival in clear cell renal carcinomas (ccRCCs) in Pakistani patients. METHODS We retrieved 318 consecutive in-house cases of ccRCC resections from 2014 to 2020 through hospital archives. Histologic slide review was done for assessment of tumor necrosis, tumor stage, and World Health Organization/ISUP grade. The follow-up data to assess metastasis-free survival were available in hospital archives. RESULTS In multivariable analysis performed by logistic regression model, tumor necrosis was an independent poor prognostic indicator (P = .0001): group 1 (reference group), 0% necrosis; group 2, 1% to 10% necrosis (adjusted odds ratio [AOR], 8.71; 95% confidence interval [CI], 3.62-20.98); and group 3, more than 10% necrosis (AOR, 9.48; 95% CI, 3.99-22.725). CONCLUSIONS Tumor necrosis is an independent predictor of poor outcome in ccRCCs.

Abstract
Objective: To assess the patterns of myoinvasion of endometrial endometrioid adenocarcinoma, their frequencies in our hospital and to correlate these patterns with survival.
Study Design: Retrospective observational study.
Place and Duration of Study: Department of Pathology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore, from Aug 2019 to Apr 2020.
Methodology: All cases of endometrial endometrioid adenocarcinoma between 2015 and 2017 were retrieved from the archives, independently reviewed by two researchers, all key reporting parameters recorded in addition to the pattern of myoinvasion as per their operational definitions described by Cole and Quick. The follow-up of 3-5 years was obtained from archives and through telephonic contact for outside hospital patients. Disease free survival and relapse-associated mortality were represented through Kaplan-Meier curves.
Results: Eighty cases of myoinvasive endometrial endometrioid adenocarcinoma were reviewed. We found that infiltrating irregular gland pattern was the most frequent in all the age groups. Thirty-five (43.75%) cases showed this type of invasion, followed by broad front pattern 23 (28.75%), Microcystic Elongated and Fragmented (MELF) pattern 15 (18.75%) and adenomyotic pattern 6 (7.5%). One case showed a combination of the last two patterns, whereas adenoma malignum pattern was not seen. Follow-up of these patients showed 8 (10%) patients with relapse related mortality including 5 (62.5%) infiltrating irregular glands, 2 (25%) adenomyosis-like and 1 (12.5%) broad front pattern of myoinvasion. Seventy-two (90%) patients had recurrence free survival.
Conclusion: Frequency of infiltrating irregular pattern of myoinvasion in endometrial endometrioid adenocarcinoma is high and associated with recurrence related mortality. Recognition....................

Abstract
Ependymomas encompass a heterogeneous group of central nervous system (CNS) neoplasms that occur along the entire neuroaxis. In recent years, extensive (epi-)genomic profiling efforts have identified several molecular groups of ependymoma that are characterized by distinct molecular alterations and/or patterns. Based on unsupervised visualization of a large cohort of genome-wide DNA methylation data, we identified a highly distinct group of pediatric-type tumors (n = 40) forming a cluster separate from all established CNS tumor types, of which a high proportion were histopathologically diagnosed as ependymoma. RNA sequencing revealed recurrent fusions involving the pleomorphic adenoma gene-like 1 (PLAGL1) gene in 19 of 20 of the samples analyzed, with the most common fusion being EWSR1:PLAGL1 (n = 13). Five tumors showed a PLAGL1:FOXO1 fusion and one a PLAGL1:EP300 fusion. High transcript levels of PLAGL1 were noted in these tumors, with concurrent overexpression of the imprinted genes H19 and IGF2, which are regulated by PLAGL1. Histopathological review of cases with sufficient material (n = 16) demonstrated a broad morphological spectrum of tumors with predominant ependymoma-like features. Immunohistochemically, tumors were GFAP positive and OLIG2- and SOX10 negative. In 3/16 of the cases, a dot-like positivity for EMA was detected. All tumors in our series were located in the supratentorial compartment. Median age of the patients at the time of diagnosis was 6.2 years. Median progression-free survival was 35 months (for 11 patients with data available). In summary, our findings suggest the existence of a novel group of supratentorial neuroepithelial tumors that are characterized by recurrent PLAGL1 fusions and enriched for pediatric patients.

Abstract
Background Diffuse midline gliomas with the H3K27M mutation are now recognized as separate entities due to their unique molecular signature, clinical features, and adverse outcome. Objective To determine the morphological spectrum and survival rate of diffuse midline gliomas with H3K27M mutation. Material and methods This retrospective study was conducted between January 2015 and January 2021 at Shaukat Khanum Memorial Cancer Hospital and Research Centre. Medical records of 28 cases of H3K27M-mutated midline gliomas were retrieved. Case slides were reviewed and the pertinent histological spectrum was evaluated. Results The mean age of patients was 24.36 ± 14.06 years. There were 21 (75%) males and 7 (25%) females. Biopsy was performed in 22 (78.6%), total resection in 1 (3.6%) while subtotal resection was done in 5 (17.9%) cases. Histologically, a spectrum of morphologies was noted with pilocytic astrocytoma (WHO grade 1) at one end and glioblastoma (WHO grade IV) at the other end. Immunohistochemically, all 28 cases were positive for Histone 3 immunohistochemistry. ATRX was performed in 7 (25.0%) cases with loss of ATRX expression in 3 (10.7%) and retained expression in 4 (14.3%) cases. Ki67 was <5% in 6 (21.4%), 5-10% in 1 (3.6%), 11-15% in 1 (3.6%), 16-20% in 3 (10.7%), 21-25% in 4 (14.3%), and 26-30% in 2 (7.1%) cases. The mean survival was 8.00 ± 9.39 months. Out of 28 patients, 15 (62.5%) patients died of disease. Conclusion Diffuse midline gliomas with H3K27M mutation is an aggressive entity with a broad morphological spectrum.

Abstract
Asiatic black bear is present in variety of habitats like broad-leaves and coniferous forests, extending form sea level to 4300m elevation and change their habitat for food purpose seasonally. The present study was conducted at Kaghan and Siran Valleys, District Mansehra, Khyber Pakhtunkhwa, Pakistan to assess habitat of black bear. Line transect method was used for observation of bear signs. Twelve meter circular radius plots were selected for the concern vegetation's i.e. (trees, shrubs and herbs) and three to six plots were placed in each transect. At the result of sign survey, thirteen different categories of bear signs were recorded and encounter rate was calculated for each sign. A total of 1858 signs were observed during field surveys. Total (81%) coniferous species were recoded among trees, with the highest appearance of Pinus wallichiana (34.22%) and Spruce spp (27.76%), similarly broad leaves trees (18.56%) were also recoded from habitat plots. Most of the signs were encountered in bushy areas, whereas high number of Viburnum Spp (60.29%) was present. It is indicated that black bear prefers blend of Coniferous Trees, Viburnum and Ferns Species; probably because these plants provide enough food, protection, and meticulous shelter because more than 80% of habitat composed of these three species. Currently habitat destruction and increase in human population are the up-growing issues for wild animals (especially Asiatic black bear), which is highly sensitive to such problems. High levels of conservation efforts are recommended for the protection of black bear habitat and to avoid human interference in their territory.

Abstract
Supraglottic airway devices are commonly used to manage the airway during general anaesthesia. There are sporadic case reports of temporomandibular joint dysfunction and dislocation following supraglottic airway device use. We conducted a prospective observational study of adult patients undergoing elective surgery where a supraglottic airway device was used as the primary airway device. Pre-operatively, all participants were asked to complete a questionnaire involving 12 points adapted from the Temporomandibular Joint Scale and the Liverpool Oral Rehabilitation Questionnaire. Objective measurements included inter-incisor distance as well as forward and lateral jaw movements. The primary outcome was the inter-incisor distance, an accepted measure of temporomandibular joint mobility. Both the questionnaire and measurements were repeated in the postoperative period and we analysed data from 130 participants. Mean (SD) inter-incisor distance in the pre- and postoperative period was 46.5 (7.2) mm and 46.3 (7.5) mm, respectively (p = 0.521) with a difference (95%CI) of 0.2 (-0.5 to 0.9) mm. Mean (SD) forward jaw movement in the pre- and postoperative period was 3.6 (2.4) mm and 3.9 (2.4) mm, respectively (p = 0.018). Mean (SD) lateral jaw movement to the right in the pre- and postoperative period was 8.9 (4.1) mm and 9.1 (4.0) mm, respectively (p = 0.314). Mean (SD) lateral jaw movement to the left in the pre- and postoperative period was 8.8 (4.0) mm and 9.3 (3.6) mm, respectively (p = 0.008). The number of patients who reported jaw clicks or pops before opening their mouth as wide as possible was 28 (21.5%) vs. 12 (9.2%) in the pre- and postoperative period, respectively (p < 0.001) with a difference (95%CI) of 12.3% (6.7-17.9%). There was no significant difference in the responses to the other 11 questions or in the number of patients who reported pain in the temporomandibular joint area postoperatively. No clinically significant dysfunction of the temporomandibular joint following the use of supraglottic airway devices in the postoperative period was identified by either patient questionnaires or objective measurements.

Abstract
Intermittent hypoxia and transient arousals in obstructive sleep apnea (OSA) can lead to poor sleep quality and acute stress. Rising levels of obesity and increased incidence of OSA in young adults predisposes them to acute stress. We propose a mediation model to assess if risk of OSA is associated with acute stress and if the relationship between risk for OSA and acute stress is mediated by sleep quality. 493 healthy individuals (F = 237, M = 256) from 18 - 25 years of age (mean age 20.3 ± 1.53 years) were screened for OSA, sleep quality and acute stress using STOP-BANG questionnaire, Pittsburg Sleep Quality Index and American Psychiatry Association's National Stressful Events Survey Acute Stress Disorder Short Scale (NSESS-S), respectively. 73 participants (17.3%) were found at an intermediate and high risk of OSA by STOP BANG questionnaire. 79 (16%) participants reported level of stress as 'None'. Mild, moderate and severe stress was present in 248 (50.3%), 109 (22.1%), 51 (10.3%) and 16 (3.2%) participants, respectively. The odds of having severe and extreme stress among those at risk of sleep apnea is 2.18 times higher than that among those not at risk of sleep apnea (OR: 2.18, 95%, confidence interval: 1.37-3.51). Sobel test established that the relationship between OSA and acute stress is mediated by sleep quality. Sleep quality mediates the relationship between risk for sleep apnea and acute stress. This highlights the importance of screening for OSA in young adults, particularly young men with high BMI, presenting with high stress levels.

Abstract
This study evaluated the efficacy of epidermal growth factor (EGF) in piglets challenged with enterotoxigenic Escherichia coli K88 (ETEC). A total of 28 piglets were assigned to the following dietary treatments for 14 d: negative control (NC) (basal diet containing supernatant without EGF), PC (NC + 2.5 g antibiotic·kg−1 feed), EGF120 [basal diet + supernatant with 120 μg EGF·kg−1 body weight (BW)·d−1], and EGF180 (basal diet + supernatant with 180 μg EGF·kg−1 BW·d−1). After a 6 d acclimation period, each pig was gavaged with 6 mL (2.4 × 1013 cfu·mL−1) of ETEC on the morning of day 7. Overall, piglets fed the EGF and PC diets tended to have higher gain to feed ratio than those fed the NC diet (P = 0.063). Pigs fed EGF diets had lower rectal temperature than those fed the NC diet at 6 h after challenge (P < 0.05). Serum and ileal malondialdehyde concentrations were higher in piglets fed the NC diet compared with those fed EGF and PC diets on days 6 and 7 after challenge, respectively (P < 0.05). In conclusion, EGF has the potential to reduce oxidative stress and body temperature elevation in piglets exposed to ETEC while supporting better feed efficiency.

Abstract
Lhermitte-Duclos disease (LDD) is a relatively uncommon condition of the cerebellum. It is generally characterised as a hamartomatous lesion of posterior fossa and is common in the third and fourth decades of life. According to the World Health Organisation, it is classified as a grade I tumour with potential for recurrence. Otherwise, this disease is generally associated with good prognosis. Malignant transformation of LDD has not yet been reported. However, genetic counselling of the patient is recommended with active surveillance. Since LDD is believed to be a pathognomonic feature of Cowden syndrome, which is a multi-system autosomal dominant hereditary disorder characterised by multiple hamartomas and an elevated risk of benign and malignant neoplasms, we decided to report this important entity considering its rarity and high clinical significance.

Abstract
In the present work, bioaugmented zinc oxide nanoparticles (ZnO-NPs) were prepared from aqueous fruit extracts of Myristica fragrans. The ZnO-NPs were characterized by different techniques such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, ultraviolet (UV) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), and thermogravimetric analysis (TGA). The crystallites exhibited a mean size of 41.23 nm measured via XRD and were highly pure, while SEM and TEM analyses of synthesized NPs confirmed their spherical or elliptical shape. The functional groups responsible for stabilizing and capping of ZnO-NPs were confirmed using FTIR analysis. The ζ-size and ζ-potential of synthesized ZnO-NPs were reported as 66 nm and -22.1 mV, respectively, via the DLS technique can be considered as moderate stable colloidal solution. Synthesized NPs were used to evaluate for their possible antibacterial, antidiabetic, antioxidant, antiparasitic, and larvicidal properties. The NPs were found to be highly active against bacterial strains both coated with antibiotics and alone. Klebsiella pneumoniae was found to be the most sensitive strain against NPs (27 ± 1.73) and against NPs coated with imipinem (26 ± 1.5). ZnO-NPs displayed outstanding inhibitory potential against enzymes protein kinase (12.23 ± 0.42), α-amylase (73.23 ± 0.42), and α-glucosidase (65.21 ± 0.49). Overall, the synthesized NPs have shown significant larvicidal activity (77.3 ± 1.8) against Aedes aegypti, the mosquitoes involved in the transmission of dengue fever. Similarly, tremendous leishmanicidal activity was also observed against both the promastigote (71.50 ± 0.70) and amastigote (61.41 ± 0.71) forms of the parasite. The biosynthesized NPs were found to be excellent antioxidant and biocompatible nanomaterials. Biosynthesized ZnO-NPs were also used as photocatalytic agents, resulting in 88% degradation of methylene blue dye in 140 min. Owing to their eco-friendly synthesis, nontoxicity, and biocompatible nature, ZnO-NPs synthesized from M. fragrans can be exploited as potential candidates for biomedical and environmental applications.

Abstract
In a natural ecosystem, the pathogen-plant-insect relationship has diverse implications for each other. The pathogens as well as insect-pests consume plant tissues as their feed that mostly results in damage. In turn, plant species have evolved specialized defense system to not only protect themselves but reduce the damage also. Such tripartite interactions involve toxicity, metabolic modulations, resistance etc. among all participants of interaction. These attributes result in selection pressure among participants. Coevolution of such traits reveals need to focus and unravel multiple hidden aspects of insect-plant-pathogen interactions. The definite modulations during plant responses to biotic stress and the operating defense network against herbivores are vital to research areas. Different types of plant pathogens and herbivores are tackled with various changes in plants, e.g. changes in genes expression, glucosinolate metabolism detoxification, signal transduction, cell wall modifications, Ca2+dependent signaling. It is essential to clarify which chemical in plants can work as a defense signal or weapon in plant-pathogen-herbivore interactions. In spite of increased knowledge regarding signal transduction pathways regulating growth-defense balance, much more is needed to unveil the coordination of growth rate with metabolic modulations in bi-trophic interactions. Here, we addressed plant-pathogen-insect interaction for toxicity as well as dependnce along with plant defense dynamics against pathogens and insects with broad range effects at the physio-biochemical and molecular level. We have reviewed interfaces in plant-pathogen-insect research to show pulsating regulation of plant immunity for attuning survival and ecological equilibrium. An improved understanding of the systematic foundation of growth-defense stability has vital repercussions for enhancing crop yield, including insights into uncoupling of host-parasite tradeoffs for ecological and environmental sustainability.

Abstract
BACKGROUND The trial hypothesis was that, in a resource-constrained situation, short-course radiotherapy would improve treatment compliance compared with conventional chemoradiotherapy for locally advanced rectal cancer, without compromising oncological outcomes. METHODS In this open-label RCT, patients with cT3, cT4 or node-positive non-metastatic rectal cancer were allocated randomly to 5 × 5 Gy radiotherapy and two cycles of XELOX (arm A) or chemoradiotherapy with concurrent capecitabine (arm B), followed by total mesorectal excision in both arms. All patients received a further six cycles of adjuvant chemotherapy with the XELOX regimen. The primary endpoint was treatment compliance, defined as the ability to complete planned treatment, including neoadjuvant radiochemotherapy, surgery, and adjuvant chemotherapy to a dose of six cycles. RESULTS Of 162 allocated patients, 140 were eligible for analysis: 69 in arm A and 71 in arm B. Compliance with planned treatment (primary endpoint) was greater in arm A (63 versus 41 per cent; P = 0.005). The incidence of acute toxicities of neoadjuvant therapy was similar (haematological: 28 versus 32 per cent, P = 0.533; gastrointestinal: 14 versus 21 per cent, P = 0.305; grade III-IV: 2 versus 4 per cent, P = 1.000). Delays in radiotherapy were less common in arm A (9 versus 45 per cent; P < 0.001), and overall times for completion of neoadjuvant treatment were shorter (P < 0.001). The rates of R0 resection (87 versus 90 per cent; P = 0.554), sphincter preservation (32 versus 35 per cent; P = 0.708), pathological complete response (12 versus 10 per cent; P = 0.740), and overall tumour downstaging (75 versus 75 per cent; P = 0.920) were similar. Downstaging of the primary tumour (ypT) was more common in arm A (P = 0.044). There was no difference in postoperative complications between trial arms (P = 0.838). CONCLUSION Reduced treatment delays and a higher rate of compliance were observed with treatment for short-course radiotherapy with consolidation chemotherapy, with no difference in early oncological surgical outcomes. In time- and resource-constrained rectal cancer units in developing countries, short-course radiotherapy should be the standard of care.

Abstract
Klippel-Trenaunay Syndrome (KTS) is a rare congenital disease characterized by a triad of cutaneous hemangioma (port-wine stain), varicose veins and bone or soft tissue hypertrophy. Cases of pregnancy complicated by KTS are rare and are associated with an increased risk of thrombo-embolic phenomena and hemorrhage. In this case, 33 years old woman, Para 1 gravida 2 (P1G2) with history of previous cesarean section and diagnosed case of KTS was presented in labour emergency of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh at 36+ weeks of gestation with labour pain. She had also a prominent hypertrophy and multiple venous varicosities on both her lower limbs; more marked on left. Her MRI done just before pregnancy revealed few prominent veins in both adnexa particularly on the left with normal caliber ovarian veins and unremarkable other pelvic structures and excludes pelvic congestion syndrome. USG done at her 35 weeks of gestation had shown numerous dilated and tortuous vessels in the parametrium, indicating pelvic congestion. Emergency caesarean section was done under spinal anesthesia. There was no postpartum hemorrhage (PPH). She was discharged along with her baby without any complication on her 4th postoperative day. Successful management of patients with KTS requires multidisciplinary team approach.

Abstract
Objective: Chondroblastoma is rare benign cartilage forming tumor of bone predominantly in individuals less than 20 years of age. Recently immunohistochemical marker DOG 1 has been reported to help in the diagnosis in difficult cases where histological features overlap with other similar entities. Current study aims to assess the sensitivity and specificity of DOG 1 in the diagnosis of chondroblastomas.
Study design: descriptive cross-sectional study
Place and duration of study: The study was conducted from June 2015 to July 2017 in Department of Histopathology, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan.
Patients and methods: Total fifty-two patients were included in this study including 19 chondroblastomas, 21 giant cell tumors and 12 chondromyxoid fibromas. DOG 1 antibody was applied on all the cases
Results: DOG 1 was positive in 100 % of cases of chondroblastomas. However, intensity and proportion of staining pattern was variable among them. 78% (n=15) cases showed diffuse moderate to strong expression while 22% (n=4) cases showed focal weak expression. Only 10% (n=2) cases of giant cell tumors and 33% (n=4) of chondromyxoid fibromas expressed focal weak expression for DOG 1.
Conclusions: This study confirms 100 % expression of DOG 1 in cases of chondroblastomas but intensity and proportion of staining pattern was variable. Therefore DOG 1 may prove to be a useful immunohistochemical marker for diagnosis of chondroblastomas in the future in difficult cases in correlation with histological and radiological features.

Abstract
OBJECTIVE To observe the efficacy of platelet rich plasma on pain improvement in knee osteoarthritis patients and to explore the impact of various facotrs on pain reduction with such a treatment. METHODS The quasi-experimental study was conducted at the Armed Forces Institute of Rehabilitation Medicine, Rawalpindi, Pakistan, from October 2017 to April 2018 and comprised patients with primary knee osteoarthritis. The sample was sub-grouped into "normal", "overweight" and "obese" on the basis of body mass index. Two age-based sub-groups were also formed at ≤ 60 years and >60 years. Three injections of calcium gluconate activated 2.5ml platelet rich plasma were given in the knees at an interval of two weeks each. The pain score was calculated using the numerical rating scale at the 6th week. Data was analysed using SPSS 20. RESULTS Of the 50 patients, 26(52%) were females and 24(48%) were males. The overall mean age was 59.6±9.6 years (range: 42-75 years), with 22(44%) aged ≤ 60 years. There were 21(42%) patients who were overweight, 7(14%) had normal weight and 22(44%) were obese. There was significant pain reduction post-treatment compared to the baseline (p<0.001). The reduction in pain was not significantly related to gender, age, knee osteoarthritis grade, or body mass index (p>0.05). CONCLUSIONS Platelet rich plasma significantly improved pain in knee osteoarthritis patients regradless of all age, gender, grade and body mass index.

Abstract
BACKGROUND Secretory carcinoma of the salivary gland (SC) is a new entity that harbours a specific ETV6 gene rearrangement. The clinical behaviour of this tumour is not well-known as it is a relatively new entity but it is generally considered as a tumour of low malignant potential. The objective of the study was to find out the frequency of ETV6 translocation in cases diagnosed based on histology and immunohistochemistry, to study morphological features and immunohistochemical findings of our cases and to determine the survival and disease-free status of our patients. METHODS Twenty-five diagnosed cases of SC were retrieved from the archives of SKMCH and RC. Diagnosis was made primarily based on morphology and immunohistochemistry. Immunohistochemistry includes S100, p63, mammaglobin, DOG 1, GCDFP-15, TTF-1, GATA3, SMA, AMA, and AR. The diagnosis was further confirmed by molecular testing, i.e., Fluorescence in situ hybridization (FISH) studies to observe specific ETV6 gene break. Follow up of the patients was done by developing a questionnaire. Statistical analysis of the data was done using SPSS-23.0. RESULTS The mean age of diagnosis was 41±17.4 and the male to female ratio was 1.5:15. The mean size of the tumour was 45.48±27.35. The most common site of the tumour was parotid gland (60%). On morphology, SC showed a wide range of morphological patterns, most common being the tubular, microcystic, intraductal, and papillary. Immunohistochemical stains mammaglobin (22/22), GCDFP-15(15/15) and GATA3 (10/10) showed 100% positive result. However, all cases were negative for p63 (0/18) and DOG 1(0/11). ETV6 break was seen in 17/17 cases (100%). The mean disease-free survival was 75 months and the overall survival was 51.90±2.80 months. CONCLUSIONS This study highlights the presence of specific molecular alteration in all cases, which were diagnosed based on morphology and immunohistochemistry.

Abstract
Abstract The main objective of current study was to investigate the chemopreventive and chemotherapeutic activity of Artemisia vulgaris extract on diethylnitrosoamine induced hepatocarcinogenesis in Balb C mice. Diethylnitrosoamine (DEN: 0.9%) was prepared to induce hepatocarcinoma in Balb C mice. The extract Artemisia vulgaris (AV) was prepared by maceration technique. Mice were classified into four groups as follows: Group 1 a control group (N=7) received saline solution (3.5 μl/mg), group 2 (N=14) received diethylnitrosoamine (3.5 μl/mg) intraperitoneally once in a week for eight consecutive weeks, group 3 (N=7) received only plant extract (AV: 150 mg/kg (Body weight) once in a week, while group 4 (N=7) was given in combination of diethylnitrosoamine (3.5 μl/mg) and plant extract (AV: 150 mg/kg (body weight). After eight weeks of DEN administration, mice of group 2 were divided into two subgroups containing seven mice each; subgroup 1 was sacrificed while subgroup 2 was treated with plant extract only (150 mg/kg (body weight)) once in a week for eight consecutive weeks. The DEN injected mice significant decline in levels of albumin with concomitant significant elevations such as aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, alpha feto protein, gamma glutamyl transferase, 5 nucleotidase, glucose-6-phosphate dehydrogenase and bilirubin. The administration of A. vulgaris significantly decreased the DEN induced hepatotoxicity. Present study revealed the potential anti-cancerous nature of Artemisia vulgaris, both in case of chemopreventive and post-treatment of A. vulgaris. Further studies are needed to explore the mechanism of prevention and therapy.

Abstract
BACKGROUND The objective of the study is to analyze the expression of androgen, estrogen and progesterone receptor in different types of endometrial carcinomas and to correlate the androgen receptor expression with estrogen and progesterone receptor and the clinicopathological parameters like lymphovascular invasion, grade of the tumour, size of tumour and extent of myometrial invasion.. METHODS It is a cross-sectional analytical study design with a simple random sample of a total of 54 cases of different types of endometrial carcinomas from the year 2017. Immunohistochemical stains androgen receptor, estrogen receptor, and Progesterone receptor were applied in all the cases. The Pearson Chi-square test of independence was applied to measure association and P-value is calculated to check the significance of the results. RESULTS Androgen receptor expression was observed in 73% of low-grade endometrioid carcinomas, 62.5% of high-grade endometrioid carcinomas, 62% of serous, 20% of clear cell and 18% of carcinosarcomas, respectively. Androgen positive tumours were also positive for estrogen and progesterone in most of the cases, except 3 serous carcinomas and one low-grade endometrioid carcinoma. However, no significant relation was observed between androgen expression and prognostic parameters like the lymphovascular invasion, size of the tumour and myometrial invasion. CONCLUSIONS Maximum expression of androgen receptor was observed in endometrioid and serous carcinomas, while carcinosarcomas and clear cell carcinomas showed minimum expression with no significant correlation between androgen receptor expression and clinicopathological parameters.

Abstract
Purpose. Clear cell sarcoma of the kidney (CCSK) is an uncommon malignant renal tumor. It is the second most common renal pediatric renal malignancy after Wilms tumor. It exhibits a heterogeneous morphology, with overlapping features with its close differentials, which results in diagnostic challenges. There was no specific immunohistochemical marker in the past, to help in this regard. BCOR antibody has recently been suggested to be helpful in the differential diagnosis. We aim to study the utility of the BCOR antibody in the diagnosis of CCSK. Methods. We selected a total of 27 cases of CCSK (n = 12), Wilms tumor (n = 12), and congenital mesoblastic nephroma (n = 3). All cases were evaluated for the extent and intensity of nuclear labeling for BCOR antibody by immunohistochemistry (IHC). Results. We found that BCOR IHC was positive in 11 out of 12 cases with diffuse and strong staining in 8 of the cases. None of the cases of Wilms tumor and congenital mesoblastic nephroma were positive. Only 2 cases of Wilms tumor showed minimal and weak staining in <5% of cells. Conclusion. Diffuse and strong nuclear staining for the BCOR antibody is highly specific for CCSK among common pediatric renal malignancies. Our study confirms that BCOR IHC is a good IHC marker for the diagnosis of CCSK.

Abstract
Soil salinity is one of the primary problem for agricultural crops which causes a great loss in crop production in Pakistan and worldwide. Various approaches have been implemented to overcome salinity problem. Assembly of crops for the enhancement of salt tolerance is a good strategy to achieve cost-effective yields. Cucumber is considered as one of the leading vegetable crop around the world for the nourishment of human being as source of nutrients, minerals, and vitamins. Screening of 12 cucumber genotypes using some physiological indices, that is, seedling germination stress tolerance index, plant height stress tolerance index, root length stress tolerance index, shoot and root dry weight stress tolerance index, and shoot and root fresh weight stress tolerance index were performed for the identification of salt tolerance. Using the above characteristics genotypes, Valley and HC-999 were categorized as tolerant, Safaa and Debra as medium tolerant, while Thamin-II identified as medium sensitive and NSC-CM1 and Akbar are classified as sensitive genotypes of cucumber. According to the current study findings, the screened cucumber genotypes for salinity tolerance can also be suggested to farmers for the improved production and yield of crop at saline soil.

Abstract
OBJECTIVE The colonic inner mucus layer protects us from pathogens and commensal-induced inflammation, and has been shown to be defective in active UC. The aim of this study was to determine the underlying compositional alterations, their molecular background and potential contribution to UC pathogenesis. DESIGN In this single-centre case-control study, sigmoid colon biopsies were obtained from patients with UC with ongoing inflammation (n=36) or in remission (n=28), and from 47 patients without colonic disease. Mucus samples were collected from biopsies ex vivo, and their protein composition analysed by nanoliquid chromatography-tandem mass spectrometry. Mucus penetrability and goblet cell responses to microbial stimulus were assessed in a subset of patients. RESULTS The core mucus proteome was found to consist of a small set of 29 secreted/transmembrane proteins. In active UC, major structural mucus components including the mucin MUC2 (p<0.0001) were reduced, also in non-inflamed segments. Active UC was associated with decreased numbers of sentinel goblet cells and attenuation of the goblet cell secretory response to microbial challenge. Abnormal penetrability of the inner mucus layer was observed in a subset of patients with UC (12/40; 30%). Proteomic alterations in penetrable mucus samples included a reduction of the SLC26A3 apical membrane anion exchanger, which supplies bicarbonate required for colonic mucin barrier formation. CONCLUSION Core mucus structural components were reduced in active UC. These alterations were associated with attenuation of the goblet cell secretory response to microbial challenge, but occurred independent of local inflammation. Thus, mucus abnormalities are likely to contribute to UC pathogenesis.

Abstract
Hypertension is persistent elevation in blood pressure for 3-4 weeks. Estimated global prevalence of hypertension suggested that by the Year 2025 (29%) of adult worldwide are suffering from hypertension (1.56 billion). Hypertension complications are hemorrhage, atherosclerosis, renal artery stenosis, angina pectoris end organ damage, cardiomyopathy, myocardial infarction and retinopathy. Along with other drug class Calcium channel blocker are also used for the treatment of hypertension. In this study the possible action of the n-hexane leaves fraction of the Androsace foliosa on isolated rabbit aorta was examined. Antihypertensive activity was examined in the existence of standard agonist like phenylephrine and antagonist like Verapamil. Phenylephrine (PE 1μM) high K+ was used to steady the tissue materials. Additionally to observe the calcium channel blocking effect the tissues were treated with n-hexane segment of A. foliosa leaves. Aortic tissues were treated 4-5intervals with Ca+2- free preparation earlier to control calcium reaction curve (CRCs). Verapamil is utilized as standard calcium channel inhibitory mediator and is used as an antagonist. The Af. n-hexane leaves fraction completely inhibited the precontractions induced by Phenylephrine (1μM) and K+ (80 mM) precontractions, with EC50 standards of 1.0mM (0.3-1.0mg/mL) and 4.90mM (1-3mg/mL), respectively. Androsace foliosa n-hexane leaves fraction was tested for calcium channel inhibitory effect on isolated rabbit aorta. A. foliosa n- hexane leaves segment at the dosage of 1mg/mL block the calcium channel approximately (35±5%). Consequence indicates that A. foliosa n-hexane leaves segment block calcium channel in the similar manner as compared to the standard calcium channel blocker drug (verapamil).

Abstract
OBJECTIVE To determine the effects of autologous platelet-rich plasma on appearance of tenocytes at injured Achilles tendon entheses in rabbits. STUDY DESIGN Laboratory-based experimental study. PLACE AND DURATION OF STUDY Department of Anatomy and Pathology, Army Medical College, Rawalpindi, in collaboration with National Institute of Health, Islamabad, from March to May, 2018. METHODOLOGY Forty healthy male, 4-6 months old New Zealand white rabbits, weighing 2000-2500 gm, were randomly divided into four equal groups A, B, C and D. Group A served as control, while B, C and D were experimental groups. Injury was surgically induced at left Achilles tendon entheses of experimental groups, which were treated with injections of autologous platelet-rich plasma, at the time of induction of injury in group C and two weeks after injury in group D, while no treatment was given in group B. Animals were euthanised at the end of 12 weeks. Specimens were taken and processed for histological observations. Bonar's modified score was used to assess the appearance of tenocytes. SPSS version 21 was used for statistical analysis. Chi-square test was applied and p-value of <0.05 was taken as significant. RESULTS Experimental group B showed marked deterioration in Bonar's score as compared to the control group A. The scores were significantly improved in treatment groups C and D as compared to group B. CONCLUSION Injection of autologous platelet-rich plasma effectively improved the Bonar's modified score for appearance of tenocytes at injured entheses, 12 weeks after injury.

Abstract
BACKGROUND AND METHODS Intravenous thrombolysis for acute ischemic stroke in the Middle-East and North African (MENA) countries is still confined to the main urban and university hospitals. This was a prospective observational study to examine outcomes of intravenous thrombolysis-treated stroke patients in the MENA region compared to the non-MENA stroke cohort in the SITS International Registry. RESULTS Of 32,160 patients with ischemic stroke registered using the SITS intravenous thrombolysis protocol between June 2014 and May 2016, 500 (1.6%) were recruited in MENA. Compared to non-MENA (all p < 0.001), median age in MENA was 55 versus 73 years, NIH Stroke Scale score 12 versus 9, onset-to-treatment time 138 versus 155 min and door-to-needle time 54 min versus 64 min. Hypertension was the most reported risk factor, but lower in MENA (51.7 vs. 69.7%). Diabetes was more frequent in MENA (28.5 vs. 20.8%) as well as smoking (20.8 vs. 15.9%). Hyperlipidemia was less observed in MENA (17.6 vs. 29.3%). Functional independence (mRS 0-2) at seven days or discharge was similar (53% vs. 52% in non-MENA), with mortality slightly lower in MENA (2.3% vs. 4.8%). SICH rates by SITS-MOST definition were low (<1.4%) in both groups. CONCLUSIONS Intravenous thrombolysis patients in MENA were younger, had more severe strokes and more often diabetes. Although stroke severity was higher in MENA, short-term functional independency and mortality were not worse compared to non-MENA, which could partly be explained by younger age and shorter OTT in MENA. Decreasing the burden of stroke in this young population should be prioritized.

Abstract
We report on the ferromagnetism of Sn1−xZnxO2 (x ≤ 0.1) hierarchical nanostructures with various morphologies synthesized by a solvothermal route. A room temperature ferromagnetic and paramagnetic response was observed for all compositions, with a maximum in ferromagnetism for x = 0.04. The ferromagnetic behaviour was found to correlate with the presence of zinc on substitutional Sn sites and with a low oxygen vacancy concentration in the samples. The morphology of the nanostructures varied with zinc concentration. The strongest ferromagnetic response was observed in nanostructures with well-formed shapes, having nanoneedles on their surfaces. These nanoneedles consist of (110) and (101) planes, which are understood to be important in stabilizing the ferromagnetic defects. At higher zinc concentration the nanostructures become eroded and agglomerated, a phenomenon accompanied with a strong decrease in their ferromagnetic response. The observed trends are explained in the light of recent computational studies that discuss the relative stability of ferromagnetic defects on various surfaces and the role of oxygen vacancies in degrading ferromagnetism via an increase in free electron concentration. We report on the ferromagnetism of Sn1−xZnxO2 (x ≤ 0.1) hierarchical nanostructures with various morphologies synthesized by a solvothermal route.![]()

Abstract
Surfactant filled mesoporous silica is applied as a matrix for immobilizing the fluorescence lifetime pH-indicator acridine. We demonstrate that this type of encapsulation provides a stable and uniform chemical environment for the indicator and has good proton transport properties leading to rapid pH response times. Furthermore, the immobilising medium effectively prevents leaching of the indicator, facilitates high long-term stability and does not influence the pH sensing-range of the indicator. A material support is proposed which grants long-term stability for fluorescence lifetime pH measurements due to a homogeneous chemical microenvironment.![]()

Abstract
Acute granulomatous interstitial nephritis (GIN) is a rare cause of acute kidney injury (AKI) but treatable. It is present in 0.5 to 0.9% of native renal biopsies. Treatment with moderate dosage of steroids is associated with good prognosis. We herein review a case of a 48-year lady having AKI following drug-induced damage [non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics]. Her renal functions did not improve after one month of drug withdrawal, so renal biopsy was done that showed acute GIN. She was treated with intravenous then oral steroids that completely resolved AKI.
