BACKGROUND: Ectopic pregnancy (EP) is a serious complication of early pregnancy. In low-income countries diagnosis of EP is difficult and it is a major contributor to maternal mortality. We aimed to assess and improve the diagnostic process of women with EP. METHODS: We conducted a retrospective medical records study of all women with confirmed EP in Ndala Hospital from 2010 to 2012. We used data on demographics, symptoms, diagnostic procedures, surgical findings, treatment and post-operative status...

OBJECT: Primary steps in the cavernous angiomas (CAs) surgery are a precise lesion identification and an optimal trajectory definition. Doing so, navigation techniques allow better results compared to microsurgery alone. In this paper we define the benefits of Intra-Operative Ultra-Sound (IOUS) use in addition to standard localization systems. METHODS: We retrospectively analyzed 59 CAs comparing two groups: 34 cases of frame-based and frameless navigation-assisted microsurgery (no-IOUS group) versus 25 cases of IOUS-guided microsurgery associated with these techniques (IOUS group)...

Doppler ultrasonography is useful in monitoring intra-operative PV flow in LDLT. A retrospective cohort study included 550 pediatric recipients (<18 years) who underwent LDLT from October 2006 to August 2016 in our hospital. A total of 33 recipients (incidence 6%) were found to have insufficient intra-operative PV flow after PV reperfusion. The treatments included intra-operative stent placement (n=25), anticoagulation (n=3), thrombectomy and re-anastomosis (n=2), graft repositioning (n=1), collateral ligation (n=1), and replaced PV (n=1)...

BACKGROUND: In a previous study, we have shown that intermittent Pringle maneuver (IPM) might increase postoperative complications after hepatectomy for various indications. Complications which thought to be related to IPM were ascites, pleural effusion, wound infection and intra-abdominal collection. The aim of this study was to test the hypothesis that applying IPM during hepatectomy for hepatocellular carcinoma (HCC) could increase postoperative complications. METHODS: Between January 2013 and October 2016, eligible patients who received elective open hepatectomy for HCC were randomized to have IPM or no Pringle maneuver (NPM)...

Filariasis is a global health problem targeted for elimination. Curative drugs (macrofilaricides) are required to accelerate elimination. Candidate macrofilaricides require testing in preclinical models of filariasis. The incidence of infection failures and high intra-group variation means that large group sizes are required for drug testing. Further, a lack of accurate, quantitative adult biomarkers results in protracted timeframes or multiple groups for endpoint analyses. Here we evaluate intra-vital ultrasonography (USG) to identify B...

Kidney cancer is the third most common urologic malignancy and a 2% annual increase in the incidence has occurred over the past two decades, largely because of the increased utilization of imaging. The majority of these tumors are small, so the indications for nephron-sparing surgery and for minimally invasive surgery are continually expanding. Complex kidney lesions, such as those completely endophytic, are still a challenge even for experienced surgeons. Our objective is to demonstrate the operative technique for laparoscopic partial nephrectomy with the aid of intra-operative ultrasound in a man with a totally endophytic renal lesion...

Several molecularly imprinted polymers (MIPs) have been synthesized for the first time using various synthetic cannabinoids (JWH007, JWH015 and JWH098) as template molecules. Ethylene dimethacrylate (EDMA) was used as a functional monomer for all cases. Similarly, divinylbenzene (DVB) and 2,2'-azobisisobutyronitrile (AIBN) were used as cross-linker and initiator, respectively. The prepared MIPs have been fully characterized and evaluated as new selective adsorbents for micro-solid phase extraction (μ-SPE) of synthetic cannabinoids in urine...

Teresa M Kieser, David P Taggart
The "Achilles heel" of coronary artery bypass graft (CABG) surgery is graft patency. While long-term patency is determined by the type of conduit and the progression of graft and native vessel disease, short-term patency is affected by intra-operative technical issues. Transit-time flow measurements and epicardial ultrasound have been shown to accurately assess intra-operative graft patency. This review will examine the evidence to support the premise that intra-operative graft assessment is essential in determining graft patency and should be the standard of care when performing CABG surgery...

BACKGROUND: Gallbladder cancer is unusually seen but can result in highly mortality rate. It makes challenge to diagnose for clinicians due to present asymptomatic or non-specific clinical presentation including abdominal pain, anorexia. It usually also accompanies with cholelithiasis (incidence is 1-2%) and incidentally detected by radiologic examination such as ultrasound, computed tomography or intra-operative intervention accidentally. Gallbladder cancer results in highly fatal malignancy because it is difficult to early detect...

PURPOSE: The current standard of care for women diagnosed with early stage breast cancer is breast-conserving surgery (BCS) followed by external beam radiation therapy, commonly delivered over 3-6 weeks. As an alternative, select patients can undergo intra-operative radiation therapy (IORT) at the time of BCT. This technique delivers a single fraction of radiation at the time of surgery, enabling patients to undergo both surgery and radiation in a single session. Our current study analyzed the value of incorporating breast MRI into the routine work-up of patients deemed eligible for IORT, to quantify the impact on patient eligibility and requirement for additional work-up...

BACKGROUND: Intravascular ultrasound (IVUS) has been recommended as an adjunct to thoracic endovascular aortic repair (TEVAR) as computed tomography (CT) in injured patients may inaccurately determine the true aortic diameter. We hypothesize that CT and IVUS offer discordant measurements of aortic diameter in trauma patients and that each modality may result in different graft size estimates for TEVAR. METHODS: Patients treated by TEVAR for blunt aortic injury from June 2011 to 2016 were reviewed...
