Identification of post-kala-azar dermal leishmaniasis (PKDL) is important due to the long and toxic treatment and the fact that PKDL patients may serve as a reservoir for visceral leishmaniasis (VL). We summarized the published literature about the accuracy of diagnostic tests for PKDL. We searched Medline for eligible studies investigating the diagnostic accuracy of any test for PKDL. Study quality was assessed using QUADAS-2. Data were extracted from 21 articles including 43 separate studies. Twenty-seven studies evaluated serological tests (rK39 dipstick, ELISA, DAT, and leishmanin tests), six studies molecular tests, eight microscopy, and two cultures. Only a few of these studies reported a valid estimate of diagnostic accuracy, as most were case-control designs or used a reference standard with low sensitivity. The included studies were very heterogeneous, for example, due to a large variety of reference standards used. Hence, no summary estimates of sensitivity or specificity could be made. We recommend well-designed diagnostic accuracy trials that evaluate, side-by-side, all currently available diagnostics, including clinical symptoms, serological, antigen, molecular, and parasitological tests and possible use of statistical modelling to evaluate diagnostics when there is no suitable gold standard.

Background: Timely diagnosis and intervention of acute appendicitis reduces morbidity and mortality associated with the disease condition. The study aimed to evaluate the etiology of acute appendicitis, to analyze the sensitivity of modified Alvarado scoring system and radiology in the diagnosis of acute appendicitis and to correlate the observations of laboratory tests, operative findings with the histopathological report of specimen of appendix.Methods: This was a prospective study done on 100 patients with clinical symptoms of acute right lower abdominal pain suggestive of appendicular origin during the period from February 2015 to January 2016 in the department of surgery thorough clinical assessment, laboratory investigations, ultrasound findings as were done for all patients. After confirming the diagnosis of AA the patients had operative intervention and specimens were sent for histopathological study.Results: Male preponderance was seen in the study. Majority of them belongs to 21 to 30 years age group (50%). Faecolith was the most common etiological factor observed (58%). Abdominal pain (100%) was the most common clinical symptom. Alvarado score had sensitivity of 95.74% and specificity of 66.67% in diagnosing AA. In correlation to histopathological findings, ultrasonography findings showed 100% positive visualization rate in all 71 cases. Elevated ESR (94%) had high diagnostic accuracy as confirmed by HPE finding (96.81%) which is statistically significant (p<0.000).Conclusions: Alvarado scoring system, elevated ESR levels and USG findings of the appendix can be considered as adjuncts to clinically diagnose the AA, to improve the diagnostic accuracy thereby consequently the rate of negative appendicectomy can be reduced and thus decreases the complication rates.

Background: About 30% of patients presenting to surgical outpatient department has lower gastrointestinal (LGI) symptoms. Colonoscopy is a low risk and at the same time investigation of choice in these patients which allows visualization of the entire colon and the terminal portion of ileum. This study was done to find out the diagnostic accuracy of colonoscopy in relation to the clinical symptoms of the disease.  Methods: This was a prospective, hospital based study from February 2014 to March 2019 carried out at Nepalgunj Medical College and Teaching Hospital. The colonoscopy diagnosis was compared with the clinical symptoms and further confirmed with histological examination.  Results: 341 patients underwent colonoscopy. There were 234 (68.62%) males and 107 (31.37%) females with the male to female ratio of 2.18: 1. The age ranged from 16 to 81 with the mean age of 59.63±10.37. The most common presenting symptom was per rectal bleeding (40.34%) the after were alteration in bowel habit (17.30%), constipation (12.90%), hematochezia (11.43%). The least common indication for colonoscopy was unexplained anemia. Haemorrhoids were the most common findings consisting 32.55%. In 19.94% it was normal. Majority had various inflammatory conditions, among them 10.85% had proctocolitis, 2.34% were suspected to have ulcerative colitis. There were 17(4.98%) patients with colonic and 13(3.18%)with rectal carcinoma. 10.55% had colorectal polyps. Out of 111 patients suspected to have hemorrhoids clinically 102 had same findings on colonoscopy. Similarly 34 patients presenting with chronic diarrhea with bleeding and 59 with alteration in bowel habit where inflammatory conditions were suspected had similar findings on colonoscopy in 29 and 34 patients respectively. Similarly the suspicion of malignancy on clinical basis was also correlated on colonoscopy. The inflammatory conditions diagnosed on colonoscopy were confirmed in 85.04 % by histology. Similarly malignancy and the presence of polyps diagnosed on colonoscopy were confirmed by histology in 97.05% and in 97.22% cases respectively. Conclusion: Colonoscopy is a safe and effective investigation to diagnose various colorectal conditions. There was a correlation between the clinical symptoms and the colonoscopicdiagnosis especially in conditions like inflammatory and neoplastic colorectal diseases. When combined with histology the diagnostic accuracy can be near 100% in conditions like inflammatory and benign or malignant diseases.

Background and Purpose: Evaluation of the lung apices using computed tomography angiography of the head and neck during acute ischemic stroke (AIS) can provide the first objective opportunity to screen for coronavirus disease 2019 (COVID-19). Methods: We performed an analysis assessing the utility of apical lung exam on computed tomography angiography for COVID-19–specific lung findings in 57 patients presenting with AIS. We measured the diagnostic accuracy of apical lung assessment alone and in combination with patient-reported symptoms and incorporate both to propose a COVID-19 era AIS algorithm. Results: Apical lung assessment when used in isolation, yielded a sensitivity of 0.67, specificity of 0.93, positive predictive value of 0.19, negative predictive value of 0.99, and accuracy of 0.92 for the diagnosis of COVID-19, in patients presenting to the hospital for AIS. When combined with self-reported clinical symptoms of cough or shortness of breath, sensitivity of apical lung assessment improved to 0.83. Conclusions: Apical lung assessment on computed tomography angiography is an accurate screening tool for COVID-19 and can serve as part of a combined screening approach in AIS.
