On the contrary, negative appendectomy subjects one to unnecessary surgery and its physiological and psychological consequences. Among the various available modalities of diagnosis of appendicitis, Ultrasonography(USG) is easily accessible, non invasive, less time consuming, low cost investigation no radiation hazards. So, USG is appropriate diagnostic modality in our country.Methods: This prospective observational study was carried out from January 2011 to June 2011, in the radiology department of Bir hospital. Total of 80 cases with clinical impression of acute appendicitis were enrolled. These patients underwent surgery for suspected acute appendicitis. Details of signs and symptoms, lab findings including Total Leukocyte count (TLC), Differential Leukocyte Count (DLC) and USG findings were recorded. Intra-operative and histopathology findings were also recorded. The findings were analyzed to assess accuracy of ultrasonography in acute appendicitis. Histopathological report was considered the goal standard.Results: A total of 93 cases clinically diagnosed as acute appendicitis were subjected for USG. Out of 93 cases, 80 cases underwent surgery. Among 80 cases, sonography showed acute appendicitis in 56 cases out of which 54 was proved by histopathology as well. However, ultrasonography was not able to detect appendicitis in 9 cases. The sensitivity and specificity of USG for acute appendicitis were 87.7% and 88.2% respectively. The positive and negative predictive values were 96.4% and 62.5% respectively. Overall negative appendectomy rate of 21.2% had been used a basis for decision making, the rate of error being 13.7%.Conclusion: Ultrasonography is a fairly accurate and safe modality in acute appendicitis. It can be useful in reducing negative appendectomy rate.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126865197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It accounts for 0.4-1 % of all deliveries. With the advent of ultrasonography, though abruptio placentae has been diagnosed however the sensitivity is less. Those patients clinically suspicious of abruption placenta with negative ultrasound findings can have positive intrapartum findings suggestive of abruptio. Fetal outcome is associated with the gestational age. Preterm deliveries with abruption have higher incidence of perinatal morbidity and mortality as compared to term pregnancies.Methods: It is a prospective study conducted in Manipal Teaching Hospital, Pokhara from July 2017 to July 2018. All the cases of more than twenty eight weeks gestation, singleton pregnancies without preexisting maternal medical diseases suspicious of abruption placentae were included in the study. Ultrasonological and intrapartum findings were recorded. Data was analyzed using SPSS (VERSION16).Results: Out of forty patients presented with per vaginal bleeding, sixteen were diagnosed as placental abruption either clinically or ultrasonographically. Only ten patients had positive ultrasound findings of retroplacental clot or subchorionic hemorrhage. Out of six patients with negative ultrasound findings, only four had positive Intrapartum findings suggestive of abruption placenta. The specificity (100%) of ultrasound in diagnosing abruption was more than the sensitivity (71.43%) and the accuracy was 75%.Conclusion: Ultrasound is less sensitive in diagnosing abruption placenta and the lesser the gestational age, the more in the increase in perinatal morbidity and mortality.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133699623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

B -mode Ultrasonography was used to measure the thickness of thyroid isthmus in transverse plane. Mean thickness of isthmus for male and female was obtained and Pearson correlation test was used to see the relationship with various factors.Results: Among 485 individuals between 1 to 83 years of age, 221 were males and 264 were females. Maximum individuals (72.99%) were from hilly region and minimum (3.30%) were from Himalayan region. Mean thickness of isthmus was 3.097 ± 1.009 mm (range 1.0 to 6.8 mm). It was 3.114 ± 0.9513 mm for male and 3.083 ± 1.056 mm for female. Isthmus thickness best correlated with total thyroid volume (r=0.373, p=0.0001). Isthmus thickness also positively correlated with body mass index (r=0.355, p =0.0001), body surface area (r= 0.296, p=0.0001), weight (r =0.334, p=0.0001) and height (r =0.130, p =0.004) of the individuals.Conclusion: This study estimated the normal reference value of thyroid isthmus thickness. As isthmus thickness correlated well with total thyroid volume, it can roughly guide the thyroid volume and help assessment of thyroid size in diffuse thyroid disease.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115922255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
