OBJECTIVE S-2 alar iliac (S2AI) screws are commonly used as anchors for lumbosacral fixation. A serious potential complication of screw insertion is major vascular injury due to anterior or caudal screw deviation. To avoid screw deviation, the pelvic inlet view on intraoperative fluoroscopy images is recommended. However, there has been no detailed investigation of optimal fluoroscopic incline with the pelvic inlet view. The purpose of this study was to investigate the safety margins and to optimize fluoroscopic settings to avoid screw deviation with 2 reported insertion techniques using 3D analysis software and CT...

Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations...

RATIONALE: Hepaticarterioportal fistula (APF) is a rare cause of portal hypertension and gastrointestinal hemorrhage, and presents as abnormal communication between the hepatic artery and portal vein. Percutaneous liver biopsy is a main iatrogenic cause of AFP. However, non-iatrogenic, abdominal, trauma-related APF is rarely reported. PATIENT CONCERNS: A 29-year-old man presenting with severe, watery diarrhea was transferred to our hospital, and his condition was suspected to be acute gastroenteritis because he ate expired food and suffered a penetrating abdominal stab wound 5 years ago...

Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The Adrenal Incidentaloma (AI) is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1...

BACKGROUND: Hepatitis B virus (HBV) infection is assumed to be the major cause of chronic liver disease (CLD) in sub-Saharan Africa. The contribution of other aetiological causes of CLD is less well documented and hence opportunities to modulate other potential risk factors are being lost. The aims of this study were to explore the aetiological spectrum of CLD in eastern Ethiopia and to identify plausible underlying risk factors for its development. METHODS: A cross-sectional study was undertaken between April 2015 and April 2016 in two public hospitals in Harar, eastern Ethiopia...

Accurate and automatic organ segmentation from 3D radiological scans is an important yet challenging problem for medical image analysis. Specifically, as a small, soft, and flexible abdominal organ, the pancreas demonstrates very high inter-patient anatomical variability in both its shape and volume. This inhibits traditional automated segmentation methods from achieving high accuracies, especially compared to the performance obtained for other organs, such as the liver, heart or kidneys. To fill this gap, we present an automated system from 3D computed tomography (CT) volumes that is based on a two-stage cascaded approach-pancreas localization and pancreas segmentation...

Chilaiditi's sign is a radiological finding that occurs when the small or large intestine is positioned superior to the liver in the sub-diaphragmatic space. This is typically an asymptomatic radiological sign, but when symptoms occur, e.g., abdominal pain, nausea, emesis, it is termed Chilaiditi's syndrome. Currently, majority of the cases of Chilaiditi's syndrome, described in the literature, requiring operative intervention are due to large bowel obstruction or colonic volvulus. The following is a single case report of a patient presenting to Keesler Medical Center in Biloxi, Mississippi...

Segmental zoster paresis is an uncommon complication of herpes zoster, and abdominal wall pseudohernia is rare. Previous reports have emphasized the involvement of anterior rami of spinal nerves, while the involvement of posterior rami has been less frequently reported. We aimed to elucidate the involvement of posterior rami of spinal nerves in abdominal wall pseudohernia. Four patients with a diagnosis of abdominal wall pseudohernia underwent needle electromyography (nEMG) and magnetic resonance imaging (MRI)...

Biopsies of liver masses that prove to be hepatocellular carcinomas (HCCs) are associated with a risk of seeding the abdominal or chest wall with tumor cells. The reported frequency of seeding varies greatly in the literature. We performed a retrospective cohort study in a large integrated health care system to examine rates of seeding in patients with HCC who had targeted liver biopsies, ablations, or both performed by community radiologists. We reviewed pathology and radiology records to determine the occurrence of wall seeding, defined as a chest or abdominal wall lesion along a definite or probable needle tract...

Spontaneous splenic rupture is a quite rare entity that may develop secondary to some special situations (lymphoma, post-abdominal surgey etc). In the literature, the case of a patient has been reported following thoracic surgery. In a patient who had undergone right upper lobectomy for pulmonary carcinoma, signs of acute abdomen and low levels in the hemogram were detected on the fifth postoperative day; therefore, the patient underwent further investigations. A radiological evaluation revealed splenic rupture, and the patient was operated on...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a common condition that may initially look simple but may conceal other diseases capable of accelerating its natural history or even simulating it. We describe four cases presenting as COPD with emphysema that were reclassified on the basis of certain clinical characteristics and the radiological pattern. CASE REPORTS: A 52 year old never smoking woman presenting with emphysema was eventually diagnosed as having lymphangioleiomyomatosis on the basis of an abdominal CT scan showing kidney angiomyolipomas...

Point-of-care ultrasound (POCUS) has been gaining greater traction in recent years as a way to quickly (and cost-effectively) assess for conditions including systolic dysfunction, pleural effusion, abdominal aortic aneurysms (AAA), and deep vein thrombosis (DVT). It involves limited and specific ultrasound protocols performed at the bedside by the health care provider who is trying to answer a specific question and, thus, help guide treatment of the patient. In this article, we will review the evidence for the use of POCUS in 4 areas: the cardiovascular exam, the lung exam, the screening exam for AAAs, and the evaluation for DVT...
