“…Prior studies have acknowledged this limitation as well. 2,8 In the present study, the hydatid cysts (n=8) appeared as sharply marginated round or oval hypodense masses with a thin rim. Wall calcifications were seen in 87.5% cases.…”

BACKGROUND:Of the various pathologies that afflict the liver, liver masses form an important group. Computed tomography (CT) is the imaging modality most often used to evaluate focal liver lesions. OBJECTIVE: To characterize focal hepatic lesions using multi detector computed tomogram (MDCT) and determines its sensitivity and specificity in diagnosing various lesions. MATERIALS AND METHODS:The study was conducted on hundred patients in the Department of Radiodiagnosis and Imaging, Government Medical College, Amritsar from August 2012 to October 2014. Patients with clinical symptoms, laboratory finding referable to the hepato-biliary system, palpable right upper quadrant mass or incidentally detected liver masses with ultrasound or CT were included in the study. The MDCT findings were correlated with serology, histopathology, surgical findings or with therapeutic response in 75 out of 100 patients. Sensitivity and specificity of CT scan in diagnosing and characterizing focal hepatic lesions was then calculated. RESULTS: Out of 100 patients, 64(64%) patients had benign and 36(36%) had malignant lesions. On later histopathological or serological correlation, definite diagnosis was made in 75 cases. The sensitivity and specificity of multidetector CT scan for the detection and characterization of amebic abscess, pyogenic abscesses, hydatid cyst, primary hepatic malignancies and metastasis was 94.7% and 96.4%, 80% and 98.3%, 100% and 100%, 87.5% and 98.5%, 100% and 98% respectively. Thus, in the present study, sensitivity of MDCT in diagnosing focal hepatic lesions was found to be between 80-100% and specificity to be between 96.4-100%. CONCLUSIONS: MDCT is a highly sensitive noninvasive tool for detection and characterization of focal hepatic lesions.

Postoperative recurrence of cystic hydatidosis

et al. 2012

View full text Add to dashboard Cite

Background: Surgical management is the basic treatment for hydatid disease. Overall, the recurrence rate appears to be high (4.6%-22.0%). The purpose of this study was to report our results in the management of recurrent hydatid disease, evaluating the methods for identifying recurrence, prognostic factors and therapeutic options. Methods:We retrospectively reviewed the medical records of patients who underwent surgery for cystic hydatidosis between 1970 and 2003.

“…Moisture variability is considered in this model, and the recycling ratio is estimated on a daily scale. The recycling ratio of the Yangtze River and the Yellow River basin was estimated (Kang et al 2005) using the model developed by El-tahir et al (1992). The recycling ratio had strong periodicity in the Yangtze River basin.…”

Changes in precipitation recycling over arid regions in the Northern Hemisphere

Changes of precipitation recycling (PR) in Northern Hemisphere from 1981 to 2010 are investigated using a water recycling model. The temporal and spatial characteristics of recycling in arid regions are analyzed. The results show that the regional precipitation recycling ratio (PRR) in arid regions is larger than in wet regions. PRR in arid regions has obvious seasonal variation, ranging from more than 25 % to less than 1 %. Furthermore, in arid regions, PRR is significantly negatively correlated with precipitation (correlation coefficient r = −0.5, exceeding the 99 % significance level). Moreover, the trend of PRR is related to changes in precipitation in two ways. PRR decreases with increasing precipitation in North Africa, which implies that less locally evaporated vapor converts into actual precipitation. However, in Asian arid regions, the PRR increases as precipitation reduces, which implies that more locally evaporated vapor converts into rainfall. Further, as PRR mainly depends on evapotranspiration, the PRR trend in Asian arid regions develops as temperature increases and more evaporated vapor enters the atmosphere to offset the reduced rainfall.
