Chronic nausea and vomiting: a diagnostic approach
(Future Drugs Ltd., 2022) Niriella, M.A.; Jayasena, H.; Withanage, M.; Devanarayana, N.M.; de Silva, A.P.
INTRODUCTION: Chronic nausea and vomiting (CNV) are commonly encountered symptoms in medical practice. CNV is the presenting symptom in a variety of gastrointestinal and non-gastrointestinal disorders. However, in a significant percentage of patients without an obvious underlying cause, CNV poses a significant diagnostic challenge to the evaluating physician. AREAS COVERED: A comprehensive clinical history and physical examination form the foundation for further diagnostic work-up. In the present review, we discuss the diagnostic approach to CNV, highlighting the epidemiology, pathophysiology, causes, and modes of evaluation of this condition. Specific investigations, carefully guided by clinical assessment and tailored for each patient, would be more beneficial in diagnosing CNV than empirically performing a blanket of investigations. EXPERT OPINION: Whilst CNV remains a historically challenging diagnostic and therapeutic dilemma, research into this topic is limited. Hence, there is a growing call for more research into diagnostic modalities for CNV. With scientific advancement and further research, it is hoped that easy-to-use, cheap, noninvasive novel diagnostic modalities for CNV will be available soon.
Mistakes in the management of iron deficiency anaemia: A narrative review
(Taylor & Francis, 2024) Niriella, M.A.; Jayasena, H.; Withanachchi, A.; Premawardhena, A.
INTRODUCTION Anaemia occurs due to an imbalance between erythrocyte production and loss. This imbalance can be due to ineffective erythropoiesis, blood loss or haemolysis. Whilst there are many causes for anaemia, iron deficiency anaemia (IDA) remains the predominant cause worldwide.AREAS COVERED: There have been many updated guidelines on the management of IDA in the past few years. As the reasons for IDA are many, evaluation requires thorough analysis and focused investigations. As an asymptomatic disease in the early stages, IDA can lead to many mistakes in its management. This review highlights potential mistakes in assessing and managing IDA and recommendations to avoid them.CONCLUSION The effective management of IDA necessitates a comprehensive and multidisciplinary approach. By recognising and addressing the common mistakes highlighted in this narrative review, healthcare professionals can improve patient outcomes, minimise complications, and enhance the overall quality of care.
Splenic stiffness measurement combined with liver stiffness measurement compared with Baveno VII criteria in predicting the presence of Oesophageal and Gastric varices in patients with compensated advanced liver cell disease (cALCD)
(Cureus, 2024) De Silva, A.P.; Niriella, M.A.; Nishad, N.; Jayasundara, H.; Jayasena, H.; Samarawickrama, V.T.; Ranawaka, C.; Basnayake, K.; De Silva, S.T.; De Silva, H.J.
INTRODUCTION Liver stiffness measurement (LSM) using vibration-controlled transient elastography (VCTE) is being increasingly used as a screening tool to predict varices. Our aim was to test the utility of Baveno VII criteria and other combinations of LSM, platelet count (PC), and splenic stiffness measurement (SSM) to predict the presence of varices in a cohort of Sri Lankan patients with compensated advanced liver cell disease (cALCD).METHODS Consecutive patients with newly diagnosed Child-Pugh class A cALCD (non-viral, BMI<30) were recruited prospectively. They underwent gastroscopy. LSM and SSM were taken using vibration-controlled transient elastography (VCTE) (Echosens FibroScan 502 Touch; Echosens SA, Paris, France) by a single operator who was unaware of endoscopy findings. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of different Baveno VII criteria to predict the varices and different combinations of LSM, SSM, and PC were also explored.RESULTS One hundred and seventy-four individuals were recruited. The mean age was 61.4 ((95% CI: 59.7-62.8) years. A total of 110 individuals were males, and 106 had varices. Our results indicated that the three Baveno VII criteria had sensitivities of 61%, 63%, and 42%, and specificities of 79%, 77%, and 87% to predict varices. SSM>30kPa alone and in combination with LSM>15kPa had sensitivities of 81 and 75%, specificities of 72 and 83%, PPVs of 82 and 87%, NPVs of 71% and 67%, and accuracies of 78 and 78%, respectively, to predict varices.CONCLUSION Baveno VII criteria had a low sensitivity but high specificity in predicting the presence of varices. However, SSM>30kPa alone or in combination with LSM>15kPa had better sensitivity, specificity, PPV, NPV, and accuracy in predicting varices.
The use of personal protective equipment in endoscopy: what should the endoscopist wear during a pandemic?
(Taylor & Francis, 2021) Jayasena, H.; Abeynayake, D.; Niriella, M.; de Silva, H.J.; de Silva, A.
Endoscopists are at high risk of exposure and nosocomial transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus) when performing endoscopic procedures due to the highly aerosol generating nature of these procedures. At present, there is still no consensus among endoscopists with regards to the type of protective equipment to be worn by healthcare workers, when performing endoscopy during the coronavirus 2019 (COVID-19) pandemic. This review encompasses a summary of currently published guidelines related to the use of personal protective equipment (PPE) when performing endoscopic procedures during the COVID-19 pandemic. With increasing calls to rationalize the use of PPE due to shortages in global supply chains, the review offers a concise summary on the most appropriate and adequate use of PPE when performing endoscopy during the pandemic. It is expected that these adaptations in the use of PPE during the pandemic will help to improve standards of care and safety of healthcare workers.
