Abstract Objective: To assess the diagnostic ability of abbreviated protocols of MRI (AP-MRI) compared with unenhanced MRI (UE-MRI) in mammographically occult cancers in patients with dense breast tissue.Materials and Methods: The retrospective analysis consisted of 102 patients without positive findings on mammography who received preoperative MRI full diagnostic protocols (FDP) between January 2015 and December 2018. Two breast radiologists read the UE, AP, and FDP. The interpretation times were recorded. The comparisons of the sensitivity, specificity and area under the curve of each MRI protocol, and the sensitivity of these protocols in each subgroup of different size tumors used the Chi-square test. The paired sample t-test was used for evaluating the difference of reading time of the three protocols.Results: Among 102 women, there were 68 cancers and two benign lesions in 64 patients and 38 patients had benign or negative findings. Both readers found the sensitivity and specificity of AP and UE-MRI were similar (p>0.05), whereas compared with FDP, UE had lower sensitivity (Reader 1/Reader 2: p=0.023, 0.004). For different lesion size groups, one of the readers found that AP and FDP had higher sensitivities than UE-MRI for detecting the lesions ≤10 mm in diameter (p=0.041, p=0.023). Compared with FDP, the average reading time of UE-MRI and AP was remarkably reduced (p < 0.001).Conclusion: AP-MRI had more advantages than UE-MRI to detect mammographically occult cancers, especially for breast tumors ≤10 mm in diameter.

Introduction: COVID-19 pandemic has overwhelmed the healthcare system of Pakistan. There has been observation regarding changes in pattern of patient presentation to emergency department (ED) for all diseases particularly cardiovascular. The aim of the study is to investigate these changes in cardiology consultations and compare pre-COVID-19 and COVID-19 era. Hypothesis: There is a significant difference in cardiology consultations during COVID era as compared to non-COVID era. Method: We collected data retrospectively of consecutive patients who visited emergency department (ED) during March-April 2019 (non-COVID era) and March-April 2020 (COVID era). Comparison has been made to quantify the differences in clinical characteristics, locality, admission, type, number, and reason of Cardiology consults generated. Results: We calculated the difference of 1351 patients between COVID and non-COVID era in terms of cardiology consults generated from Emergency department, using Chi-square test. Out of which 880 (59%) are male with mean age of 61(SD=15). Analysis shows pronounced augmentation in number of comorbidities [Hypertension(6%), Chronic kidney disease (6%), Diabetes (5%)] but there was 36% drop in total cardiology consultations and 43% reduction rate in patient’s ED visit from other cities during COVID era. There was 60% decrease in acute coronary syndrome presentation in COVID era, but fortuitously drastic increase (30%) in type II myocardial injury has been noted. Conclusion: There is a remarkable decline observed in patients presenting with cardiac manifestations during COVID era. Lack in timely care could have a pernicious impact on outcomes, global health care organizations should issue directions to adopt telemedicine services in underprivileged areas to provide timely care to cardiac patients.

Background: Umbilical cord stump is a budding point for bacterial colonization subsequently leading to sepsis that contributes to high neonatal morbidity and mortality, if not properly managed. Antiseptic care can significantly reduce omphalitis and ultimately improve newborn survival. Objective of this study was to see the efficacy of 4% chlorhexidine use to prevent umbilical cord infection in neonates.Subjects and methods: It was a comparative analytical study conducted in Neonatal unit, Sir Ganga Ram Hospital (SGRH) Lahore from July, 2016 till January, 2017. One hundred neonates were enrolled and randomized into two equal group by simple random method (50 each). In one group, nothing was applied to cord while in chlorhexidine group, 4% chlorhexidine gel was applied on umbilicus and around it, once daily for 7 days or till cord detached whichever came early. First application was done by a nurse followed by duly trained mother/caregiver. The signs of omphalitis (redness, pus or localized oedema) were observed and recorded for each neonate in both groups. Chi square test was used to see the difference in omphalitis in these groups with p˂ 0.05 considered as statistically significant result.Results: Out of 100 neonates, 29 (58%) and 23 (46%) males while 21 (42%) and 27 (54%) females neonates belonged to dry care and chlorhexidine group respectively. Nineteen (38%) neonates with dry cord had omphalitis compared to only 5 (10%) in chlorhexidine group (p 0.001). Neonates with chlorhexidine application showed prolonged mean cord separation time (7.9±1.5 days) compared to dry care (6.1±1.8 days). Conclusion: The use of 4% Chlorhexidine was effective to lower omphalitis compared to neonates with dry cord care.

Background：Esophagogastric junction tumor (EGJ) is a rare but fatal disease with a rapid rising incidence worldwide in the late 20 years, and it lacks a convenient and safe method for diagnosis. This study aimed to evaluate the potential of serum CYR61 as a biomarker for the diagnosis of EGJ tumor. Methods: Enzyme-linked immunosorbent assay (ELISA) was used to estimate CYR61 levels in sera of 152 EGJ tumor patients and 137 normal controls. Receiver operating characteristics (ROC) was carried out to evaluate the diagnostic accuracy. The Mann–Whitney’s U test was used to compare the difference of serum levels of CYR61 between groups. And chi-square tests were employed to estimate the correlation of the positive rate of serum CYR61 between/among subgroups. Results: Serum CYR61 levels were statistically lower in EGJ tumor and early-stage EGJ tumor patients than those in normal controls (P&lt;0.0001). The sensitivity, specificity, and the area under the curve (AUC) of this biomarker in EGJ tumor were 88.2%, 43.8% and 0.691, respectively, and those for early stage of EGJ tumor were 80.0%, 66.4% and 0.722, respectively. Analyses showed that there was no correlation between the clinical data and the levels of CYR61 (P&gt;0.05). Conclusion: This study showed that CYR61 might be a potential biomarker to assist the diagnosis of EGJ tumor.

Intraepithelial Lesions

Background: ThinPrep® (TP) cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW) protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS) with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW) group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS) 4.9% (135), low-grade squamous intraepithelial lesions (LSIL) 3.7% (102), and high-grade squamous intraepithelial lesions (HSIL) 1% (28). From the 2739 control cases, 96.3% were satisfactory with ASCUS 5.5% (151), LSIL 5.1% (139), and HSIL 0.7% (19). The prevalence of ASCUS interpretations was similar (P = 0.33). Although there were 32% more HSIL interpretations in the AAW group (28 in AAW vs. 19 in non-AAW), the difference was statistically insignificant (P = 0.18). AAW category; however, had significantly fewer LSIL interpretations (P = 0.02). The percentage of UNS cases remained higher in the AAW group with statistical significance (P < 0.01). Conclusions: While AAW had a significantly higher percent of UNS interpretations, the protocol was effective in rescuing 94.2% of specimens which otherwise may have been reported unsatisfactory. This improved patient care by avoiding a repeat test. The prevalence of ASCUS and HSIL interpretations between AAW and non-AAW groups were comparable. Though not statistically significant, HSIL interpretations were relatively higher in the AAW group. LSIL interpretations showed lower prevalence in AAW group.

Job satisfaction is a general attitude towards one’s job, the difference between the amount of reward workers receive and the amount they believe they should receive. Employee is a back bone of every organization, without employee no work can be done. So employee’s satisfaction is very important.Employees will be more satisfied if they get what they expected, job satisfaction relates to inner feelings of workers. As Udumalpet and Palani Taluk are famous for paper industries, the main aim of this study is to analyze the satisfaction level of paper mill employees. Chi-Square test and percentage analysis have been used in this study to analyze the job satisfaction of paper mill employees in Udumalpet and Palani Taluk. The study shows that only 44% of the employees are satisfied with the working conditions, 31% of them with the welfare facilities, 44% of them with the accident compensation, and 42% of them are satisfied with the rewards provided and 52% of them are satisfied with the grievance handling procedure. The organization may give importance to certain factors such as Canteen, rest room facilities, rewards, recognition and promotion policy so that satisfaction of the employees may be improved further.

Measurement of lumbar range of motion (LROM) is a routine method in the examination of patients with low back pain. There is no standard technique which may be used to accurately describe the range of motion in the different plane. So in present study, an attempt has been made to compare goniometric measurement with tape measurement for its sensitivity, specificity and accuracy for measuring spine mobility in normal adults. In this cross sectional study, 137 healthy adults between the ages of 18-26 years of age were included consecutively and assessed using Tape method and goniometry for trunk mobility in all planes (sagittal, frontal and transverse). The association of goniometry with tape method was assessed using chi square test. The study showed that the difference between goniometry and tape method was statistically significant (p value <0.05) for all movements except flexion (p value 0.215). Also the sensitivity, specificity and accuracy of goniometry is not as good as tape method except for flexion compared to tape method. So, from this study we can conclude that Goniometry was not as good as tape method for all movements except forward flexion where both can be equally used.

: An emergency can be encountered anytime and anywhere. Minimal knowledge about medical emergency and their etiology, primary protocol for management must be known to avoid potential consequences. Hence, the present study was undertaken to compare the knowledge, and ability to handle the medical emergencies among the dental students. A cross-sectional survey was conducted among 100 randomly selected dental students (post-graduate students and interns) comprising of two groups of students those who had underwent training and those who did not. The data obtained was analyzed using the SPSS for windows version 22.0 released 2013. Independent chi square test was used for comparison of responses and independent student t-test was used for the comparison of mean scores. The significance level was set at p&#60;0.001. : The average mean knowledge and ability score was 68% & 61.4% respectively among the participants. On further comparison of mean knowledge & ability scores between the participants with & without basic life support training, participants with BLS training showed better knowledge than those without training and the difference was statistically significant between the two groups (p&#60;0.001%). The study found deficiencies in the knowledge and ability of untrained graduates to deal with medical emergencies as compared to trained.

Geographic information system-based multi-criteria decision analysis (GIS-MCDA) is a process of decision making where geographical data and value judgments are integrated. Analytic hierarchy process (AHP) is a useful technique in MCDA for determining weights. This study focuses on the evaluation of GIS-MCDA using different uncertainty levels in AHP. Best suitable sites for tiger habitats are located and analyzed in Sariska Wildlife Reserve, India using crisp and fuzzy AHP in GIS-MCDA, and thereafter, an optimal habitat suitability model is proposed. The percentage deviation over the uncertainty levels ranges slightly over 5%. The relative difference between CAHP and FAHP is nearly 2.7%. Chi-square test reveals relationship between the degree of uncertainty and the difference between the maps. For real-world situations with increased variability, fuzzification is preferred and shows the best results. The worldwide declining status of the tigers is a serious threat to the overall biodiversity, and the methods adopted in this study thus target their conservation and management.
