Background: Eclampsia is a leading cause of maternal death, with classical neurological symptoms that include headache, nausea, vomiting, cortical blindness, coma and convulsions. Computed tomography (CT) scan helps in diagnosing and management of eclampsia in pregnant women. The present study was done with the objective to analyse the findings of CT scan of brain in eclampsia, to identify the prevalence of neurovascular complications in these cases and to determine if these findings can be of value in determining the prognosis of this disorder.Methods: This was a prospective study done on 100 patients with eclampsia. All of the 100 patients were screened with CT scan brain at Institute of Obstetrics and Gynaecology, Egmore, Chennai during the period from August 2008 to August 2009. All the data were analyzed and compared between the groups of positive CT scan and negative CT scan observations.Results: Out of 100 patients, positive CT scan findings were noticed in 15 patients. Of them, 7 patients expired, and 8 patients survived after treatment. Of the expired patients (7), 5 of them expired due to brain haemorrhage, and 1 patient died with cerebral oedema and 1 with brain infarction. Cerebral odema (46%) was the most common positive CT finding.  Parietal region of brain was the most common (40%) affected area.Conclusions: CT scan of brain provides valuable information in determining the prognosis and the prevalence of neurovascular complications in Eclampsia.

BACKGROUND Acute pancreatitis (AP) is described as acute inflammation of the pancreas with or without peripancreatic abnormalities. The present study describes the role of computed tomography in the evaluation and grading of acute pancreatitis. Acute pancreatitis is a dynamic disease having biphasic mortality peaks due to two overlapping phases, which include early and late due to increased obesity, ageing of population, alcohol abuse, increased gall stone incidence, the worldwide AP incidence is increasing. Most important causes of AP in developing countries such as India include increased alcohol consumption. Contrast enhanced computed tomography plays an important role in diagnosis of the disease and helps in determining the prognosis of the disease. Modified CT severity index scoring system is the most commonly used scoring system for assessment of the severity of the disease. METHODS The present study is a prospective study of patients presenting with signs and symptoms of acute pancreatitis referred to the Department of Radio Diagnosis at Katuri medical college. This study comprised of 50 patients with clinical suspicion / diagnosis of acute pancreatitis, raised pancreatic biochemical parameters like serum amylase and serum lipase. Contrast enhanced computed tomography was performed in these patients, findings reported, and the disease was classified using modified CT scoring index system (MCTSI). RESULTS The mean age of the patients in the present study was 42.3 ± 12.28 years. Most of the patients presented with abdominal epigastric pain, abdominal distension. Acute pancreatitis was divided into acute oedematous pancreatitis and necrotising pancreatitis, the former being common. Complications included, ascites, pleural effusions, splenic vein thrombosis, portal venous thrombosis, and haemorrhages. CONCLUSIONS Contrast enhanced CT is useful to differentiate between oedematous and necrotising types of pancreatitis. The MCTSI helps in better evaluation of pancreatic necrosis grading. The modified computed tomography score index correlation with the development of local and systemic complications in acute pancreatitis is well established. Ideally, conducting contrast enhanced computed tomography (CECT) after 48 - 72 hours of acute attack, increases the probability of identifying necrotising pancreatitis. CT in particular has an overall accuracy of about 87 % and sensitivity and specificity of 100 % in the recognition of pancreatic necrosis.

A Prospective Study

We performed a prospective study to evaluate the values of dynamic four-dimensional computed tomography in assessing suspected chronic scapholunate instability. Forty patients were evaluated with radiographs, arthrography, and four-dimensional computed tomography. On plain radiographs and computed tomography, we found 16 patients with definite scapholunate instability, five with questionable scapholunate instability, and 19 with absence of scapholunate instability. We used four-dimensional computed tomography to evaluate the size of the scapholunate gap during radioulnar deviation. The mean and maximal values of the gap size were lowest in the patients with absence of scapholunate instability and highest in those with definite scapholunate instability. When comparing the scapholunate gap sizes of the patients with absent and questionable scapholunate instability, the range of the gap sizes was significantly higher in the patients with questionable scapholunate instability. We conclude that four-dimensional computed tomography aids assessment of chronic scapholunate instability, which allows the differentiation between patients without and those with definite or questionable scapholunate instability.

A Prospective Study

Many patients presenting with haematuria undergo intravenous urography, renal tract ultrasound and cystoscopy. Renal tract ultrasound includes imaging of the bladder, which can significantly increase scan times by necessitating bladder filling, which can impact negatively on appointment scheduling. Little published literature exists on whether ultrasound of the bladder in the presence of haematuria is of any clinical benefit. This study aims to redress this by comparing bladder ultrasound to the gold standard of cystoscopy and also by assessing temporal implications in this patient group. A prospective study was undertaken where 96 consecutive urology-referred patients had their bladder ultrasound findings compared with the findings of cystoscopy under the headings of mass, trabeculation, diverticulum, stone and fistula. Ultrasound had poor sensitivity (47.8%), but good specificity (94.5%) in detecting the predefined bladder pathologies with a poor Kappa score of 0.33 when compared with cystoscopy. In addition, there was a significant time burden placed on the list by including bladder scanning as part of the renal tract sonographic assessment. In conclusion, bladder ultrasound is not shown to be a clinically useful adjunct to cystoscopy for the detection of bladder pathology. We would recommend that, in the setting of haematuria, ultrasound be used only for upper tract assessment.
