Background: Dengue infection is an extremely common infection in tropical countries. It is considered to be prevalent all-round the year. The aim of the study was to analyse the ultrasound features of serologically proven dengue cases. To correlate the platelet count with ultrasound features of dengue.Methods: Study included dengue patients admitted from January 2011 to December 2012. Dengue was diagnosed by IgM antibody test. All patients underwent ultrasound evaluation and platelet count testing.Results: most common finding was ascites in 43 cases (39.8%), splenomegaly in 41 cases (37.9%), right sided pleural effusion in 25 cases (23.4%), gall bladder wall thickening was present in 30 cases (27.7%) and hepatomegaly was present in 20 cases (18.5%). Presence of most of the features of ultrasound evaluation correlated with a platelet count of less than 40000 cells/mm3.Conclusions: The commonest sonographic findings were ascites and splenomegaly followed by pleural effusion and gall bladder wall thickening. Thus, presence of these ultrasound features in a febrile patient may be suggestive of dengue fever and presence of all the sonographic features may suggest a low platelet count.

Background: Dengue Fever is an acute mosquito transmitted viral infection caused by one of the 4 serotypes of the genus flavivirus which has become a major international public health problem. The diagnosis of DF is often delayed owing to time taken for availability of serology test results. Moreover, this test is expensive and not widely available. Ultrasonography (USG) is a cheap, rapid and widely available non-invasive imaging method. In recent years several studies concluded that Ultrasonography of the chest and abdomen can be an important adjunct to clinical profile in diagnosis of DF and diagnosis can be made early in the course of the disease compared with other modes of diagnosis. The aim of  the study is to demonstrate the ultrasound findings of dengue fever and also evaluate the specificity of gall bladder findings in dengue fever. Subjects and Methods: We conducted a prospective study in Govt Medical College& Hospital, Srikakulam and Konaseema Institute of Medical Sciences, Amalapuram, A.P. Study included 50 patients referred to the department of Radio-Diagnosis and Imaging for Ultrasonography with clinical suspicion of dengue fever, during a period of July 2018 to December 2019. USG of the abdomen, pelvis and chest was performed in  all cases and findings were noted. Dengue serology was performed later and all the ultrasound findings were correlated with dengue serology. Results:  In our study of 50 patients all the patients studied were diagnosed with dengue fever based on dengue serology. In our study, 100%  of our patients diagnosed with DF (by dengue serology) showed gall bladder wall thickening, 88% showed splenomegaly, 44% showed ascites. Pleural effusion was present in 30% of which 66.66% of pleural effusion was bilateral and the rest 33.33% was right sided. Isolated left sided pleural effusion was not found in our study. Hepatomegaly was present in 28% of our patients. In our study mortality and complications from dengue fever were not seen. Conclusion: Ultrasound findings in dengue fever are gall bladder wall thickening, splenomegaly, ascites, pleural effusion and hepatomegaly. In an area where DF is an epidemic, when Ultrasonography shows gall bladder wall thickening in a febrile patient with thrombocytopenia DF should be suggested On Ultrasonography, when there is gall bladder wall thickening, splenomegaly, ascites, and pleural effusion in a febrile patient with thrombocytopenia in a DF epidemic area a diagnosis of DF should be considered in a differential diagnosis until proved otherwise.

Abstract Background Dengue fever is a major public health problem with an increased incidence in recent years. Gall bladder wall thickening has been reported as one of the most common findings in dengue fever. There is a paucity of literature regarding the various patterns of gall bladder wall thickening in dengue fever and their significance in predicting the severity of disease. Methodology and Significant Findings Out of 93 seropositive patients included in the study, 54 patients with dengue fever had gall bladder wall thickening. 4 patterns of gall bladder wall thickening are demonstrated in this study. A uniform echogenic pattern in 20 patients, striated or tram track pattern in 11 patients, an asymmetric pattern in 2 patients and a honeycombing pattern in 21 patients. The range of patterns of wall thickening included normal wall thickening or uniform echogenic wall thickening in DF without warning signs, a striated or tram track pattern, and a honeycomb pattern in severe DF. Serial ultrasound done on consecutive alternate days revealed a change in the pattern of gall bladder wall thickening according to the severity of disease. Conclusion The present study revealed 4 distinct patterns of gall bladder wall thickening. The uniform echogenic pattern was found to be more prevalent in dengue fever without warning signs, while the honeycomb pattern was found to be more prevalent in severe dengue fever. A change in the pattern of gall bladder wall thickening on subsequent serial ultrasound can predict the severity of the disease.

AbstractIntroduction: Radiographic findings of dengue fever have not yet been clearly elucidated in relation to clinical and serological findings, despite the fact that two-fifths of the world population lives in areas where the virus is endemic. The current study is a retrospective analyzis of ultrasonographic (USG) features of patients presenting with probable dengue fever during the outbreak of DF of 2006 in North India.Methods: Case records of a 169 patients with probable dengue fiver were included. Ten individual sonographic parameters were reviewed vis-à-vis ascites, hepatomegaly, splenomegaly, gall bladder wall edema (GBWE), pleural effusion (right or left or both), pericardial effusion, pericholecystic collection, perinephric collection. Subjects who had GB wall thickness >3 mm as measured on ultrasound were identified as positive for GBWE. The cases were analyzed in view of their serological profile.Results: The mean age of the subjects was 27.9 +/− 13.4 years. The mean value of the platelet count was 57.4 +/− 22.3 x 103/cmm. The most common ultrasonographic feature was ascites (126, 74.6%) followed by gall bladder wall edema (122, 72%), hepatomegaly (78, 46.2%), splenomegaly (66, 39.1%) and pericholecystic collection (63, 37.3%); 48 (28.4%) subjects demonstrated evidence of pleural effusion on the right side, while 19 (11.2%) had bilateral effusion. None of the subjects had an isolated left pleural effusion. Twenty-seven (16%) subjects reported bleeding manifestations in the form of petechiae and five (3%) developed renal dysfunction. Presence of pleural and pericardial effusions was found to be specific while ascites and GBWE were identified as highly sensitive markers for seropositive Primary DF.Conclusions: Ultrasonographic evidence of ascites, pleuro-pericardial effusion, and gallbladder wall edema are rapidly aquired, non-invasive markers of dengue and can be helpful before serological investigations become available. These findings may indicate severity and may herald the onset of bleeding (petechiae) or predict the development of acute renal dysfunction.

Aim: To evaluate the frequency of gall bladder wall thickness in patients suffering from liver cirrhosis. Study design: Cross-sectional study Place and duration of study: Department of Internal Medicine, Bolan Medical Complex Hospital, Quetta from 01-01-2020 to 31-012-2020. Methodology: Sixty eight diagnosed patients of liver cirrhosis, age ranging between 20 to 60 years, were randomly selected from indoor patient department and they were further evaluated for gall bladder wall thickness.The diagnosis of liver cirrhosis and portal venous hypertension was made by ultrasonography of abdomen, especially hepatobiliary system. The gall bladder wall thickness is also evaluated by ultrasonography. Results: Mean age of the patients was 41.22±8.93 years. There were 35(51.5%) males while female patients were 33(48.5%). The mean duration of symptoms was 6.32±0.57 weeks. The duration of symptoms was ≤6 weeks in 45(66.2%) of patients, while 23(33.8%) of patients were having duration of symptoms >6 weeks. Twenty 20(29.4%) cases of liver cirrhosis patients were presented with gall bladder wall thickness, while rest 48(70.6%) were presented with normal gall bladder wall thickness on USG. Conclusion: The gall‐bladder wall thickness is very common finding associated with liver cirrhosis. It requires no surgical intervention or any other specific medical therapy. Keywords: Gall‐bladder wall thickness; liver cirrhosis; portal venous hypertension; hypoalbuminemia.

This study was designed to make a relation between gall bladder wall thickening (GBWT) measured by ultrasonography and esophageal varices (EV) measured byupper gastrointestinal endoscopy in chronic liver disease patients. Itwas cross- sectional descriptive study. 50 cases ofChronic Liver Disease were recruited. GBWT was measured by ultrasonography and upper gastrointestinal endoscopy was done for assessment of the presence and grade of EV in all cases. Among 50 cases, 34 (68%) were male and 16(32%) were female. Mean age (±SD) of the study population was 46.7 (±13.28) years of age. Esophageal varices were found in 42(84%) cases and 8(16%) cases had no varix. Among 42 cases of esophageal varices 9 cases had grade-I, 17 cases had grade-II and 16 cases had Grade-III esophageal varices. Gall bladder wall thickness up to 3mm was considered as normal. In this study GBWT value between (1-3) mm8 cases had no EV GBWT value between (3.1-5.9) mm ,10 cases had EV(9 cases had grade 1 and 1 case had grade 11 EV); GBWT value between (6-8.9) mm, 16 cases had grade 11 EV and GBWT value between (9-12) mm 16 cases had grade 111 EV. A significant statistical correlation was found between the level of GBWT and EV (P<0.001) and also between mean GBWT and EV (P<0.001). This study shows that the presence of EV is directly related to the level of GBWT and there is also association with the grade of EV and level of GBWT. This finding will permit the use of GBWT as a preliminary indirect parameter that will predict the presence EV. It can help clinicians in determining the urgency of care, especially where endoscopy facilities are not available.TAJ 2015; 28(2): 15-21
