Abstract:
Background : The purpose of this study is to evaluate if ultrasonography may be used as an useful addition to clinical and radiology profiles in diagnosing dengue fever and predicting virus severity by comparing imaging findings. The difference in sonographic characteristics observed in patients of various ages was also investigated.
Objective : The goal of this study is to determine role of ultrasound for diagnosis of complications of dengue fever in Gujrat
Materials and Methods: This is a retrospective study. From October and December 2021, 79 patients who were serologically confirmed with dengue fever were referred for ultrasound scanning of the abdomen at Aziz bhatti shaheed hospital Gujrat, and the imaging data were evaluated. The statistical kit for social science (spss) is used for data analysis.
Results: out of 76 positive dengue patients there are 71(89.9%) male and 8(10%) are female .48 (60.8%) patients showed splenomegaly, 24(30%) patients showed ascites in which 8 (10%) have pelvic ascites and 16 (20.3%) abdominal ascites, 63 (79.7%) patients showed edematous GB wall thickening, 21(26.6%) showed pleural effusion while 18 (22.8 %) have bilateral pleural effusion and 3 (3.8%) have right sided.
Conclusion: In patients presenting with fever and concomitant symptoms, sonographic signs of thickening GB wall, pleural effusion (bilateral or right side), ascites, and splenomegaly should strongly help in early diagnosis of dengue fever, especially during an outbreak.

This study was performed to find out whether ultrasound is an important adjunct to clinical and laboratory profile in diagnosing dengue fever or dengue haemorrhagic fever and to further determine whether ultrasound is useful in predicting the severity of the disease. Ultrasound was performed on 128 patients (2-9 years) with clinical suspicion of dengue fever. Serological tests were performed to confirm the diagnosis. 40 patients were serologically negative for dengue fever and later excluded from the study. Of the remaining 88 serologically positive cases, 32 patients underwent ultrasound on second to third day, repeated on fifth to seventh day of fever and in 56 patients ultrasound was done only on fifth to seventh day of fever. Of the 32 patients who underwent the study on second to third day of fever, all showed gall bladder wall thickening and pericholecystic fluid, 21% had hepatomegaly, 6.25% had splenomegaly and right minimal pleural effusion. Follow-up ultrasound on fifth to seventh day revealed ascites in 53% left pleural effusion in 22% and pericardial effusion in 28%. Of the 56 patients who underwent the study on fifth to seventh day of fever for the first time all had gall bladder wall thickening, 21% had hepatomegaly, 7% had splenomegaly, 96% had ascites, 87.5% had right pleural effusion, 66% had left pleural effusion and 28.5% had pericardial fluid. To conclude, in an epidemic of dengue, ultrasound features of thickened gall bladder wall, pleural effusion and ascites should strongly favour the diagnosis of dengue fever.

Distinguishing juxtadiaphragmatic pleural and peritoneal fluid by computed tomography (CT) is sometimes difficult. We evaluated the distribution of fluid in 50 consecutive patients with pleural effusion or ascites or both. Juxtadiaphragmatic pleural fluid was nearly always found posteromedially, whereas peritoneal fluid typically distributed lateral to the liver or spleen or both in the posterior upper abdomen. This difference in distribution is easily explained by pertinent upper abdominal peritoneal and extraperitoneal anatomy. On the basis of distribution alone, pleural and peritoneal fluid could be differentiated in 47 of 50 patients. Difficulty was encountered with loculated pleural fluid and with ascites having a large left subphrenic component; in those situations, previously reported CT signs may be helpful.

To note ultrasonographic findings used for diagnosing plasma leakage in dengue haemorrhagic fever patients.The observational retrospective study was conducted at the Holy Family Hospital, Rawalpindi and comprised records of patients with confirmed dengue infection who were screened for dengue haemorrhagic fever according to Dengue Expert Advisory Group criteria from July 1 to December 31, 2013. Each patient underwent ultrasonography for the detection of ascites, gall bladder wall thickness, pleural and/or pericardial effusion along with their quantification and localisation.Of the 240 patients, 166(69.2%) were men. The overall mean age was 28.9±12.4 years. Of the total, 215(89.5%) had ultrasonographic abnormalities, suggestive of plasma leakage. Quantification and localisation wise, mild abdominal ascites 68(47.2%), right pleural effusion 82(74.5%) and mild pleural effusion 98(89%) were commonly noted. None had pericardial effusion.Mild ascites and mild right pleural effusion were the commonest pattern of ultrasonographic leak in dengue haemorrhagic fever patients.

A recurrent unilateral pleural effusion developed without obvious cause in two patients with cirrhosis of the liver. By the demonstration of the rapid passage of a radiolabelled colloid from abdomen to thorax, these effusions were proved to be secondary to clinically undetectable peritoneal effusions. A diaphragmatic tear, which had occurred during a previous splenectomy and which was apparent only at autopsy, was the cause of peritoneopleural communication in one patient. Previous surgery could also have been responsible for the pleural effusion in the other patient.

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.

A 55-year-old man with an 11-year history of intermittent right pleural effusions had continued fevers and a large right transudative pleural effusion. Minimal ascites was noted by ultrasound examination. A communication between the thorax and intraperitoneal cavity was established by radionuclide examination of the chest and abdomen. Tc-99m sulfur colloid was injected into the peritoneal cavity, and imaging at 1 and 4.5 hours confirmed passage from the peritoneal to the pleural cavity. Repeated attempts to sclerose the pleural cavity failed to decrease the transudative accumulations. The patient was subsequently treated with the placement of a LeVeen shunt.
