Anatomic Information

Acute ureteral obstruction produces renal damage and complications that are proportional to the severity and length of the obstruction. Anatomic diagnosis of the obstruction may be insufficient to manage the patient. Intravenous urogram (IVU) is the method usually advised by radiologists to obtain functional information, but requires iodinated contrast agents. IVU anatomic information is superior to anatomic information obtained with renal scintigraphy, but normally the physician already has the anatomic information (unenhanced CT or ultrasound). A renal scan offers better physiologic information than the IVU, has neither adverse effects nor complications, is accurate to confirm or discard significant ureteral obstruction, and depicts obstruction complications. This paper presents a patient with spontaneous urine extravasation secondary to acute renal obstruction who is diagnosed with renal scintigraphy. The authors describe the scintigraphic signs of extraperitoneal, diffuse perinephric, urine extravasation and emphasize the role of renal scintigraphy in diagnosis and follow-up of renal colic.

Idiopathic retroperitoneal fibrosis (RPF) is characterised by the development of a fibrotic mass in the prelumbar or presacral area which becomes clinically significant when it causes ureteral obstruction. New imaging techniques have improved accuracy of the morphological approach to the disease, but urography and sequential renal scintigraphy are still important for assessing ureteral involvement. The role of imaging techniques is discussed and current diagnostic and therapeutic tools are evaluated.

Objective: In this study, we aimed to emphasize the role of radiological imaging in determining the treatment of a patient, who tested positive for COVID-19 and diagnosed with acute appendicitis during the pandemic. Methods: A 31-year-old patient presented to the emergency department due to abdominal pain. Ultrasound examination, thoracic and pelvic CT scan were performed. Results: Non-complicated appendicitis can be treated conservatively with antibiotics. Treatment can be maintained by starting with IV antibiotics and bridging therapy with oral antibiotics. Conclusion: This study aims to summarize how radiological follow-up can be used to decide on the suitability of the patient for appropriate medical treatment as an alternative to surgery in a patient, whose gold standard treatment is emergency surgical intervention, which is frequently encountered in the emergency department during the COVID-19 pandemic.

Abstract Background and Aim: Appendicography had been used in the diagnosis of chronic appendicitis. To our knowledge, the role of endoscopic retrograde appendicography for the diagnosis of acute appendicitis remains unknown. The aim of this study was to evaluate the role of endoscopic retrograde appendicography for the diagnosis of acute appendicitis.Patients and Method: Patients with suspected acute appendicitis between December 2013 and November 2015 at Second Affiliated Hospital of Harbin Medical University underwent endoscopic retrograde appendicography. The findings and complication were analyzed retrospectively.Results: Thirty-three patients (20 men and 13 women, average age 44 ± 18 years) with suspected acute appendicitis were studied. Acute appendicitis was ruled out by normal endoscopic retrograde appendicography in 24% and confirmed in 69.6% (23). In 2 patients (8%) appendiceal orifice cannulation failed. Colonoscopic findings in acute appendicitis were mucosal hyperemia and edema of appendiceal orifice (83%), outpouring of pus from the appendiceal orifice (74%), and swollen cecal mucosa (61%). Appendicograpic findings were either normal or in acute disease showed diffuse lumenal dilation (diameter: 0.8 ± 0.4 mm), partial stenosis (43%), stiffness or inflexibility (87%) and filling defects (22%). There were no complications during or after follow-up for a median of 13 months (IQR: 9-24 months).Conclusions: Endoscopic retrograde appendicography appears to be a reliable and safe method to confirm or exclude the diagnosis of acute appendicitis and prevent unnecessary appendectomy.

Abstract. Background: Little is known about the role of resilience in the likelihood of suicidal ideation (SI) over time. Aims: We examined the association between resilience and SI in a young-adult cohort over 4 years. Our objectives were to determine whether resilience was associated with SI at follow-up or, conversely, whether SI was associated with lowered resilience at follow-up. Method: Participants were selected from the Personality and Total Health (PATH) Through Life Project from Canberra and Queanbeyan, Australia, aged 28–32 years at the first time point and 32–36 at the second. Multinomial, linear, and binary regression analyses explored the association between resilience and SI over two time points. Models were adjusted for suicidality risk factors. Results: While unadjusted analyses identified associations between resilience and SI, these effects were fully explained by the inclusion of other suicidality risk factors. Conclusion: Despite strong cross-sectional associations, resilience and SI appear to be unrelated in a longitudinal context, once risk/resilience factors are controlled for. As independent indicators of psychological well-being, suicidality and resilience are essential if current status is to be captured. However, the addition of other factors (e.g., support, mastery) makes this association tenuous. Consequently, resilience per se may not be protective of SI.

Summary Aim: Even with careful observation, the overall false-positive rate of laparotomy remains 10-15% when acute appendicitis was suspected. Therefore, the clinical efficacy of Tc-99m HMPAO labeled leukocyte (TC-WBC) scan for the diagnosis of acute appendicitis in patients presenting with atypical clinical findings is assessed. Patients and Methods: Eighty patients presenting with acute abdominal pain and possible acute appendicitis but atypical findings were included in this study. After intravenous injection of TC-WBC, serial anterior abdominal/pelvic images at 30, 60, 120 and 240 min with 800k counts were obtained with a gamma camera. Any abnormal localization of radioactivity in the right lower quadrant of the abdomen, equal to or greater than bone marrow activity, was considered as a positive scan. Results: 36 out of 49 patients showing positive TC-WBC scans received appendectomy. They all proved to have positive pathological findings. Five positive TC-WBC were not related to acute appendicitis, because of other pathological lesions. Eight patients were not operated and clinical follow-up after one month revealed no acute abdominal condition. Three of 31 patients with negative TC-WBC scans received appendectomy. They also presented positive pathological findings. The remaining 28 patients did not receive operations and revealed no evidence of appendicitis after at least one month of follow-up. The overall sensitivity, specificity, accuracy, positive and negative predictive values for TC-WBC scan to diagnose acute appendicitis were 92, 78, 86, 82, and 90%, respectively. Conclusion: TC-WBC scan provides a rapid and highly accurate method for the diagnosis of acute appendicitis in patients with equivocal clinical examination. It proved useful in reducing the false-positive rate of laparotomy and shortens the time necessary for clinical observation.

Background: the present study was under taken to determine the role of CA-125 in the diagnosis of acute appendicitis (AA), to prevent its complications and also in preventing negative appendicectomies in tertiary care hospital. Methods: The study was conducted at a tertiary care and research center between 01/03/2018 to 30/06/2019. Patients admitted to the surgery department with diagnosis of AA were considered for the study. After informed consent, a, standardized history was obtained as a case Performa. Serum samples from all the cases with clinical diagnosis of AA were obtained and stored. Only the cases with histopathologically approved AA were included in the study. Cases operated for clinical diagnosis of AA, but not histopathologically proven AA was not included in the study. CA125 levels in cases with definitive diagnosis of AA were measured. Results: In present study, ROC curve analysis revealed the sensitivity of 87.27 % and specificity of 90.91 % when the CA 125 cut-off value of > 16.8 was taken to diagnose acute appendicitis. AUC was 0.911 with a standard error of 0.0292. Conclusion: In this study we have observed that CA125 showed a positive correlation with acute appendicitis, that was statistically not significant (P>0.05). We didn’t evaluate the correlation with the disease severity. We consider that CA125 can be used as a marker in acute appendicitis cases although further research is still needed.
