Two patients presented with fever and acute abdominal pain. Acute cholecystitis was diagnosed when ultrasound examination showed a double-contour gallbladder wall. Radiography showed gas in the gallbladder wall in both cases, indicating emphysematous cholecystitis. This demonstrated that gas in the gallbladder wall may go undetected by ultrasound at the time when it could still be detected by conventional radiography of the abdomen. Awareness of the value of conventional radiography in these cases has an important diagnostic significance which may affect patient management.

Abstract Purpose To investigate the accuracy of ultrasound in the diagnosis of adnexal torsion. Materials and Methods Retrospective cohort analysis of 322 women, presenting to a tertiary medical center with acute abdominal pain, who underwent gynecological examination, sonographic evaluation and laparoscopic surgery, between 2010 and 2016. Findings for adnexal torsion were compared among three groups: positive sonographic findings consistent with surgically confirmed adnexal torsion (true positive, n = 228); negative sonographic findings inconsistent with surgically confirmed adnexal torsion (false negative, n = 42); and positive sonographic findings inconsistent with a surgical diagnosis other than adnexal torsion (false positive, n = 52). Outcome measures were sensitivity and positive predictive value of ultrasound, and its specific features, for the diagnosis of adnexal torsion. Results The sensitivity of ultrasound for adnexal torsion diagnosis was 84.4 %, and the positive predictive value was 81.4 %. Edematous ovary and/or tube, as well as positive whirlpool sign had the highest sensitivity and positive predictive value. The false-negative group had the highest frequency of ovarian cysts (p = 0.0086) and the lowest frequency of ovarian edema (p < 0.0001). The false-positive group had the lowest proportion of pregnant women (p = 0.0022). Significantly more women in the true-positive group had a prior event of adnexal torsion (p = 0.026). Conclusion Ultrasound examination is highly accurate in the diagnosis of adnexal torsion. Clinicians should be aware of the presence of demographic and clinical characteristics that may positively or negatively affect sonographic diagnostic accuracy.

Four studies were conducted to examine the data collection procedures and diagnostic accuracy of Navy Hospital Corpsmen for patients “with acute abdominal pain and to determine the compatibility of their skills with the requirements of a computer-aided diagnostic system for abdominal pain. Findings suggest that instruction in specific data collection procedures results in an increase in the amount of data collected. It does not appear to improve either the accuracy of the data collected or the diagnosis. The instructed corpsmen collected more of the required data for effective use of a computer-based diagnostic system for abdominal pain.

Past Data

The paper describes an application of Bayes’ Theorem to the problem of estimating from past data the probabilities that patients have certain diseases, given their symptoms. The data consist of hospital records of patients who suffered acute abdominal pain. For each patient the records showed a large number of symptoms and the final diagnosis, to one of nine diseases or diagnostic groups. Most current methods of computer diagnosis use the “Simple Bayes” model in which the symptoms are assumed to be independent, but the present paper does not make this assumption. Those symptoms (or lack of symptoms) which are most relevant to the diagnosis of each disease are identified by a sequence of chi-squared tests. The computer diagnoses obtained as a result of the implementation of this approach are compared with those given by the “Simple Bayes” method, by the method of classification trees (CART), and also with the preliminary and final diagnoses made by physicians.

<p class="p1"><span class="s1">Mycotic aneurysm of the superior mesenteric artery (SMA) is a rare complication of infective endocarditis. We report a case with infective endocarditis involving the aortic valve complicated by multiple septic embolisms. The patient was treated with antibiotics for 6 weeks. During preparation for surgical treatment, the patient developed acute abdominal pain and was diagnosed with a ruptured SMA aneurysm, which was successfully treated with an emergency operation of aneurysm ligation. The aortic valve was replaced 17 days later and the patient recovered uneventfully. In conclusion, we present a rare case with infective endocarditis (IE) complicated by SMA aneurysm. Antibiotic treatment did not prevent the rupture of SMA aneurysm. Abdominal pain in a patient with a recent history of IE should be excluded with ruptured aneurysm.</span></p>

Abstract Background Hydatid cysts are fluid-filled sacs containing immature forms of parastic tapeworms of the genus Echinococcus. The most prevalent and serious complication of hydatid disease is intrabiliary rupture, also known as cystobiliary fistulae. In this study, a sporadic case of biliary obstruction, cholangitis, and septicemia is described secondary to hydatid cyst rupture into the common bile duct and intraperitoneal cavity. Case presentation A 21-year-old Iranian man was admitted to the emergency ward with 5 days of serious sickness and a history of right upper quadrant abdominal pain, fatigue, fever, icterus, vomiting, and no appetite. In the physical examination, abdominal tenderness was detected in all four quadrants and in the scleral icterus. Abdominal ultrasound revealed intrahepatic and extrahepatic biliary duct dilation. Gallbladder wall thickening was normal but was very dilated, and large unilocular intact hepatic cysts were detected in segment IV and another one segment II which had detached laminated membranes and was a ruptured or complicated liver cyst. Conclusion Intrabiliary perforation of the liver hydatid cyst is an infrequent event but has severe consequences. Therefore, when patients complain of abdominal pain, fever, peritonitis, decreased appetite, and jaundice, a differential diagnosis of hydatid disease needs to be taken into consideration. Early diagnosis of complications and aggressive treatments, such as endoscopic retrograde cholangiopancreatography and surgery, are vital.
