Abstract Objective: To determine diagnostic accuracy of BISAP in comparison to Ranson scores in predicting mortalities and severities in patients with acute pancreatitis coming to the emergency department. Methods: Cross-sectional study conducted in Department of Emergency Medicine, Aga Khan University Hospital, Stadium road Karachi, Pakistan. 136 patients were selected via non-probability consecutive sampling technique, those who fulfilled the criteria of inclusion. BISAP score was applied in the emergency department (ED) & the patients were followed in ward/intensive care unit where Ranson scores were calculated in the following 48 hours. Both the scores were calculated and compared for the prediction of severity and mortality for each patient. All the obtained data was recorded in Performa. Results: In this study 136 patients, who fulfill the inclusion criteria were selected. On the basis of BISAP and Ranson score; mild acute pancreatitis to moderate acute pancreatitis (MAP to ModAP) was diagnosed in 123 (90.4%) and 119 (87.5) patients and severe AP (SAP) in 13 (9.6%) and 17 (12.5%) patients respectively. Specificity (Sp) 94.62% vs 91.54%, Sensitivity (Sn) 100.0% vs 100.0%, negative predictive value (NPV) 100.0% vs 100.0%, positive predictive value (PPV) 46.15% vs 35.29% and diagnostic accuracy (DA) 94.85% vs 91.91% of BISAP vs Ranson scores respectively. Conclusion: It was concluded from the study that BISAP and Ranson score are very reliable tool for identification of acute pancreatitis patients at higher risk of severity and mortality. BISAP and Ranson score has same sensitivity but BISAP score has higher specificity than Ranson score. Continuous...

Objective: To compare the accuracy of Upper lip bite test with modified Mallampati classification for predicting the difficultlaryngoscopic intubation. Study Design: Cross sectional Study. Place and duration of study: The study was carried out at Department ofAnaesthesiology, Intensive Care and Pain management, Combined Military hospital, Rawalpindi from September 2008 to August 2009.Patients and Methods: Four hundred patients undergoing elective surgery meeting the inclusion/exclusion criteria were enrolled afterwritten informed consent. The airways of the patients were evaluated by using the modified Mallampati classification (MMP) and theUpper lip bite test (ULBT). MMP class 3 or 4 and ULBT class 3 were considered as indicators of difficult intubation. The laryngeal view wasgraded by Cormack and Lehane classification (Gold standard). Grade 1 or 2 was considered to represent easy intubation and grade 3 or 4to represent difficult intubation. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy werecalculated for both the tests separately by using the 2×2 table. Results: ULBT had a higher accuracy of 94%, specificity of 99.2% andpositive predictive value 70% compared to MMP accuracy of 82.7%, specificity of 84.4% and positive predictive value of 22.7%.Conclusions: The diagnostic accuracy of the Upper lip bite test was more than the modified Mallampati classification. We suggest that itbe compared with the other prevailing tests as well which are often used to assess difficult intubations.

Objective: To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) in detection of intra-axial gliomas in suspected cases keeping histopathology as gold standard. Methods: This cross-sectional study was conducted at Dow Institute of Radiology, DUHS from October 2017 - April 2018. Patients of either gender aged 30-70 years presenting with headache were included. Patients already diagnosed and referred for follow up were excluded. MRI was performed on 1.5T scanner by a trained MRI technician. T1, T2, FLAIR, diffusion weighted and T1 post contrast images were acquired and reviewed by two radiologists having more than five years post fellowship experience. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of MRI for intraaxial gliomas was calculated taking histopathology findings as gold standard. Results: Mean age of the patient`s was 51.71 ±10.85 years. Positive intraaxial gliomas on MRI were observed in 123 (79.90%) patients while on histopathology, positive intraaxial gliomas were observed in 131 (85.10%) patients. Diagnostic accuracy of MRI in detection of intra-axial gliomas taking histopathology findings as gold standard showed sensitivity, specificity, positive predicted value (PPV), negative predicted value (NPV) and overall diagnostic accuracy as 89.31%, 73.91%, 95.12%, 54.84% and 87.01%. Conclusions: MRI has high sensitivity, moderate specificity and high diagnostic accuracy in detection of intraaxial gliomas. doi: https://doi.org/10.12669/pjms.37.1.2489 How to cite this:Munir S, Khan SA, Hanif H, Khan M.

Background: CT and MRI modalities are considered a gold standard for the diagnosis of hydrocephalus. The more readily available and cheap options like sonography are being sought out for the diagnosis of this entity. Objectives: To determine the accuracy of cranial ultrasonography in the diagnosis of hydrocephalus keeping CT scan as a gold standard. Study design: Cross-sectional study Place and duration of study: Department of Pediatrics, Combined Military Hospital, Rawalpindi, from 01-01-2017 to 30-06-2017 Materials and Methods: A total of 121 children with a clinical diagnosis of hydrocephalus were selected and subjected to ultrasound of the head. Subsequently, a CT scan of the head was done and both modalities were compared. The diagnostic accuracy of the ultrasound was determined to keep CT findings as to the gold standard. Results: The mean age was 51.36 ± 34.01 days. The male gender was dominant as 81 (66.9%) patients were males. Ultrasonography of the head detected 93 (76.9%) patients with hydrocephalus while CT scan detected 90 (74.4%). Sensitivity, specificity, PPV, NPV and accuracy of USG to diagnosed hydrocephalus were 88.9%, 58.1%, 86.0%, 64.3% and 80.99% respectively Conclusion: Ultrasonography of head is a valuable screening tool for the diagnosis of hydrocephalus.

Objective: To determine the diagnostic accuracy of doppler ultrasound in the diagnosis of testicular carcinoma, by taking histopathology as gold standard. Methods: This cross-sectional study was carried out at Radiology department of Liaquat University of Medical and health Sciences (LUMHS), from November 2017 to October 2019. All the clinically diagnosed cases of testicular carcinoma, those who referred for doppler ultrasound and histopathology of testes, were included. After taking informed consent all the study participants underwent testicular histopathology after doppler ultrasound. All of the information was entered into a research proforma. SPSS version 20 was used to analyze the data. Results: Overall, 70 patients of suspected testicular carcinoma were studied. The mean age of the cases was 38.38+4.55 years. Most of the cases 47(67.1%) were poor. As per Doppler ultrasound (U/S) findings out of all 55.7% cases had diagnosed testicular carcinoma, while histopathologically it was observed in 45.7% of the cases. Diagnostic accuracy of Doppler U/S in testicular carcinoma diagnosis was observed to be 77%, followed by sensitivity (SE) 84%, specificity (SP) 71%, positive predictive value (PPV) 78% and negative predictive value (NPV) 84%. Conclusion: Doppler ultrasound observed to be a non-invasive, uncomplicated, lack of pain, effective and easily available diagnostic tool for early diagnosis of testicular carcinoma.

ABSTRACT OBJECTIVE: To determine the diagnostic accuracy of Electrocardiography (ECG) of Left Ventricular Hypertrophy, taking echocardiography as a gold standard. SUBJECTS & METHODS: It was a Cross-Sectional Study. The study was conducted in the Medicine Department, Services Hospital, Lahore from February 19, 2018, to August 19, 2018. A total of 300 cases were enrolled. Standardized a 12-lead ECG was used in subjects by Cardiofax electrocardiograph paper speed at 25mm/sec. Two dimensionally (2D) guided M Mode echocardiographic measurements were taken and the presence/absence of LVH was recorded. The collected data was entered and analyzed in computer software SPSS software v25.0. A 2x2 table was drawn to calculate the Sn, Sp, PPV, NPV and diagnostic accuracy of ECG for LVH taking Echocardiographic findings as a gold standard. RESULTS: Out of 300 cases, 172(57.33%) were male and 128(42.67%) as females. The mean age was 38.72±5.64 years. Accuracy of electrocardiography (ECG) for LVH diagnosis taking echocardiography as the gold standard was calculated as 85.21%, 84.18%, 82.88%, 86.36% and 84.67% as Sn, Sp, PPV, NPV, and diagnostic accuracy respectively. CONCLUSION: Diagnostic accuracy of Electrocardiography (ECG) for LVH diagnosis is higher and this diagnostic modality can be used in areas where echocardiography is not available.
