Background: Discrimination between tuberculous (TB) and malignant pleural effusions is a real practical challenge because both exist as exudative lymphocytic type. Transthoracic ultrasonography not only identifies and quantifies pleural effusion but also displays sonographic septations, which are frequently seen in TB pleural effusions and can help in differentiation between tuberculosis and malignancy successfully, without any invasive procedure. We designed this study to determine the diagnostic usefulness of these septations for tuberculous and malignant pleural effusions. Material and Methods: This prospective study was conducted in the OPD of Gulab Devi Chest Hospital Lahore, Pakistan, a 1500 bedded tertiary care hospital, from November 2016 to February 2018. Total of 339 consecutive cases, aged 14-83 years with radiological evidence of pleural effusion were included in the study. After detailed history, thorough physical examination, radiological, haematological and biochemical findings were recorded. Pleural fluid macroscopic, cytological, microbiologic and biochemical analysis results were also recorded. Ultrasonography was done, septated and non-septated pleural effusions identified and findings were noted. SPSS-16 was used for statistical evaluation. Fisher Exact test was utilized for comparison between TB and malignant cases with P-value < 0.05 taken as significant. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy and positive likelihood ratio were calculated. Results: Out of total 339 cases, 49 (14.45%) were malignant and 290 (85.55%) were non-malignant. In the malignant group, only 03 cases (6.12%) showed sonographic septations. In the non-malignant group, 259/290 (89.31%) cases showed tuberculous etiology and 187/259 (72.20%) of these cases displayed sonographic septations. By considering septations as predictor of TB, statistical analysis revealed a sensitivity of 79.23%, specificity of 92.85%, PPV of 98.42%, NPV of 44.31% and diagnostic accuracy of 81.29%, respectively. Conclusions: Sonographic septations can be a valuable predictor of tuberculosis, in a population with high prevalence of the disease. We found it to be a useful feature in differentiating between a malignant and tuberculous etiology, in exudative lymphocytic pleural effusions. It can be used with confidence in patients who are unfit for interventional procedures.

Background: The incidence of prostatic carcinoma is increasing worldwide. With its high resolution, ability to provide excellent tissue characterization and multiplanar imaging capabilities, multi-parametric magnetic resonance imaging (mpMRI) plays a crucial role in detection, local staging and follow-up of carcinoma prostate. It also helps guide targeted biopsies in initial biopsy negative patient. Objectives: Study diagnostic accuracy of mp-MRI and primarily that of the three MR sequences T2, DWI and DCE in detection of prostatic cancer by correlating them with histopathology and thus whether it is feasible for a short MRI of 3 sequences to be used on a large scale in Indian scenario. Materials and Methods: A prospective study was done at a tertiary care hospital between April 2017 to November 2018 in which 50 patients who presented with suspicion of prostate cancer were referred to radiology department for evaluation using MRI. MRIexamination was done using 3T Siemens Magnetom Verio. Followed by this MRI directed TRUS guided cognitive fusion biopsy was done from the prostate. Samples were sent for histopathology. Results: Out of 50 cases studied, 24 cases (48%) were found to be malignant and 26 cases (52 %) were benign on histopathology. In our study, combined T2 + DWI + DCE gave sensitivity of 95.83 %, specificity of 57.69%, positive predictive value of 68.21 % and negative predictive value of 93.75%. Conclusion: Multiparametric MRI using T2, DWI and DCE has a high diagnostic accuracy for evaluation of prostatic cancer.

OBJECTIVE: To assess the efficacy of using an iodized talc slurry as a sclerosing agent instilled into the pleural space via a 12-French pigtail catheter for controlling malignant pleural effusions. DESIGN: A prospective study in which patients were followed until their death. SETTING: A university-affiliated tertiary-care teaching hospital. PATIENTS: Medical oncology patients admitted with symptomatic malignant pleural effusions were considered for iodized talc pleurodesis. MAIN OUTCOME MEASURES: The control of pleural effusion. Treatment failure was defined as any reaccumulation of fluid in the pleural space. RESULTS: Fifteen patients were treated for a total of 17 instillations. The median follow-up on all patients until death was 6 months (range 1–20). The most frequent adverse effect in the study group was pleuritic chest pain (60%). The probability of control of effusion, as determined by the method of Kaplan–Meier, was 81% (SEM 9.7%). The cost of preparing 5 g of iodized talc was $4.32 (US). CONCLUSIONS: Iodized talc slurry instilled through a small-bore pigtail catheter is a safe, economical, and effective treatment for malignant pleural effusion.

India has been engaged in tuberculosis (TB) control activities for over 50 years and yet TB continues to remain India’s important public health problem. The present study was conducted to compare the performance of GeneXpert MTB/RIF (GXpert) assay with composite reference standard in diagnosing cases of tubercular pleural effusion (TPE) and to evaluate the reliability of rifampicin resistance. A cross-sectional study was performed in a Department of Medicine of a rural teaching tertiary care hospital in central India. In all consecutive patients with pleural effusion on chest radiograph presenting to Department of Medicine, GXpert assay and composite reference standard was performed to evaluate the diagnostic accuracy of GXpert assay for detecting TPE in comparison to composite reference standard. Standard formulae were used to calculate the sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), positive likelihood ratios (LR+) and negative likelihood ratios (LR-). Mc-Nemar’s test was applied to compare variables. All comparisons were two-tailed. We considered the difference to be statistically significant if the P value was less than 0.05. The sensitivity of the GXpert assay in diagnosing TPE was 16.6% among 158 study participants, the specificity was 100% and diagnostic accuracy was 52.5% which was statistically significant (p value < 0.05). It had a PPV of 100% (95%CI: 88.3% - 100%) and a NPV of 47.5% (95%CI: 39.3% - 55.7%). The LR+ and LR-were 23.5 (95%CI: 1.43–38.6) and 0.83 (95%CI: 0.76–0.91) respectively. GXpert assay has a very high specificity in diagnosing TPE but has a low sensitivity. In comparison to composite reference standard Thus its clinical utility is limited when used as a standalone test. A physician’s clinical acumen in combination with routine pleural fluid analysis should be the key factor in the diagnosis of TPE in clinically and radiologically suspected patients, especially in high TB burden countries.

Background: Early diagnosis of acute pancreatitis remains a challenge in emergency set up. The early management results in better outcomes but none of the available investigations were rapid and accurate to guide the management in these patients. Hence in suspected cases of acute pancreatitis, the urinary trypsinogen 2 dipstick assay can be used to diagnose them at the earliest in the Emergency setup. The purpose of this study is to determine the accuracy of urine trypsinogen 2 assay in diagnosing acute pancreatitis. Methods: The patients presenting with symptoms consistent with acute pancreatitis to the emergency department, at a tertiary care hospital in Southern India between November 2018 to November 2019 were included in a prospective observational study after obtaining Institutional ethical committee clearance. In addition to the routine investigations done in cases of acute abdomen, patients underwent urine trypsinogen 2 dipstick test. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) were calculated. Results were compared. Results: A total of 50 cases were included in the study. The urine trypsinogen 2 dipstick test was positive in 35 of 37 patients with acute pancreatitis (sensitivity, 94.59%) and in none of 13 patients with abdominal pain but without any evidence of acute pancreatitis (specificity, 100%). The diagnostic accuracy of the urine trypsinogen 2 dipstick test was 96% in this study higher than other conventional laboratory investigations. Conclusion: This study shows that the dipstick test has high diagnostic accuracy and can be considered for regular use for diagnosing pancreatitis along with the conventional methods.

Pseudouridine in urine and plasma has been proved to be a useful tumour marker in many malignant conditions. We studied its usefulness in pleural fluid for distinguishing malignant from non-malignant pleural effusions. Pleural fluid pseudouridine concentrations in different groups of patients with pleural effusion (31 malignant, 29 benign, 16 unknown, 1 double pathology) was measured and compared. Its usefulness in distinguishing malignant from non-malignant pleural effusions was analysed by receiver-operating characteristic (ROC) curve analysis. Pseudouridine concentrations in the malignant group were significantly higher than the non-malignant group ( P < 0.017, Bonferroni adjustment) with values overlapping extensively at the lower end. The area-under-the curve (AUC) value in the ROC curve analysis was 0.675 ( P < 0.05). We conclude that the pleural fluid pseudouridine is of limited clinical value in distinguishing malignant from non-malignant pleural effusion due to its extensive overlap. However, it is useful when the concentration is higher than 65 μmol/L, which indicates malignancy.

Background: Management of pleural effusions depends on their origin whether exudates or transudates, simple or complicated with septations and pneumonia. A complicated effusion requires longer treatment. This study was carried out to find out types of effusion and their etiology.Methods: A Prospective study of 34 patients was analyzed for clinical and laboratory profile, origin and type of fluid, etiology of pleural effusion in pediatric patients.Results: Majority of the patients were in 6-11 years age group. Fever and cough were most common clinical symptoms in all type of effusion. Parapneumonic effusion was most common type of effusion followed by tuberculosis and empyema. Almost all exudates satisfied Lights criteria.Conclusions: Pleural effusions are mostly exudative in origin in pediatric age and are associated with consolidation and septations especially in empyema. In tubercular Pleural effusion, Sputum for AFB was positive in more number of patients as compared to CBNAAT in this study.

Objective: To study the diagnostic accuracy of Adenosine deaminase enzyme (ADA) in the diagnosis of tuberculous pleural effusion (TPE).Material and Methods: It was a cross-sectional descriptive study conducted in the Pulmonology departments of Lady Reading and Khyber Teaching Hospital Peshawar and department of Pathology, Khyber Medical College, Peshawar from April 2015 to Jan 2016. A total of 210 tuberculous and non-tuberculous pleural effusion patients were selected through consecutive non-probability sampling techniques. After physical and systemic examination, 3cc of pleural fluid was taken. ADA was estimated by Non-Guisti and Galanti method through the simple colorimetric method. All the data was entered in a specially designed proforma and SPSS v16 was used for statistical analysis.Results: Out of 210 tuberculous and non-tuberculous pleural effusions, the commonest cause of pleural effusion was tuberculosis followed by malignancy. In our study, Pleural fluid ADA levels have sensitivity, specificity, positive predictive value( PPV), and negative predictive value (NPV) of 95.5%, 92.3%, 92.4%, and 96% respectively in differentiating tuberculous pleural effusions from non-tuberculous lymphocytes predominant pleural effusions. Conclusion: Tuberculosis is the commonest infectious disease worldwide. A pleural fluid ADA level of ≥ 35 U/L in lymphocyte-predominant effusions makes mycobacterium tuberculosis most likely etiology. This test is not only very sensitive and specific but also it is very cheap, quick, and easy to perform by routine colorimetric method.

Introduction Multinodular goitre (MNG) is defined as multiple palpable distinct nodules in the enlarged thyroid gland. MNG can harbour malignancy in 1-10% cases. We undertook the present study to correlate the clinical, radiological and cytological features of MNG with that of final histopathological diagnosis. Materials and Methods A prospective cohort study was done in a tertiary care hospital in northern part of West Bengal from January 2018 to December 2019. Patients aged between 12 years and 75 years, presenting with MNG on clinical examination, were included in the study. We compared the pre-operative ultrasonography (USG) of neck and fine needle aspiration cytology (FNAC) reports with post-operative histopathological examination (HPE) report. Results Among 100 patients 80 were female and 20 were male. Most patients were in 41-50 years age group. For detection of malignancy in MNG, USG had 40% sensitivity, 97.78% specificity, 66.67% positive predictive value (PPV), 93.62% negative predictive value (NPV), and 92% diagnostic accuracy. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of FNAC for detection of malignancy in MNG were 20%, 93.33%, 25%, 91.3% and 86% respectively. When USG features were combined with FNAC features non-diagnostic result decreased from 6% to 2% and diagnostic accuracy for detecting malignancy in MNG increased from 86% to 90%. Conclusion USG and FNAC are complementary to each other in the diagnostic workup of MNG. USG guided FNAC is still better for reaching final diagnosis and exclusion of malignancy.

Introduction:Tuberculosis is an infectious disease with a high prevalence of about 9 million cases occurring annually. Ziehl Neelsen microscopy is the most widely used technique to detect Acid Fast Bacilli, but it is less sensitive. However, fluorescent microscopy is more helpful with simple diagnostic criteria. Gene Xpert®MTB/RIF assay is a rapid molecular assay that enables diagnosis of Tuberculosis with simultaneous detection of rifampicin resistance. Owing to this fact, we aimed at evaluating the diagnostic accuracy of Ziehl Neelsen microscopy, fluorescent microscopy and Xpert MTB/RIF keeping MTB culture (Mycobacterial Growth Indicator Tube) as a gold standard for the diagnosis of tuberculosis.Methodology:This study was carried out at a tertiary care hospital of Rawalpindi in the year 2016. Patients aged 18 to 70 years irrespective of gender with suspected TB based on history, clinical and radiological examination were included in the study. Respiratory clinical specimens including sputum, Broncho-Alveolar Lavage (BAL), and endobronchial washings were collected. Specimens were processed by MGIT (MTB culture), ZN microscopy, fluorescent microscopy and Gene Xpert MTB/RIF assay.Results:A total of 352 respiratory specimens were tested among which 160 (45%) samples were positive by culture. Out of culture positive samples, 158 samples (98.7%) were GeneXpert TB positive while 2 were negative. While only 49 (30.6%) were positive on ZN microscopy and 89 (55%) were positive on fluorescent microscopy. Out of the culture negative samples, 2 were positive with ZN microscopy, one was positive with fluorescent microscopy and 3 were positive on Gene Xpert. Sensitivity, specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and diagnostic accuracy of ZN Smear microscopy was 39%, 99.5%, 96%, 63% and 14.5% respectively. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of fluorescent smear microscopy was 55% and 99.5%, 98%, 72% and 79% respectively. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of Gene XPERT was 98% and 99%, 98%, 99% and 98% respectively.Conclusion:In countries like Pakistan where Tuberculosis is endemic, the diagnostic accuracy with highest sensitivity and specificity was Gene Xpert Polymerase Chain Reaction (PCR) MTB/RIF assay which can help in well-timed diagnosis of the disease.
