2061652 Hepatic Size in Patients With Chronic Liver Disease Among Nigerian Population: The Sokoto Experience

Abstracts 2060741 Through the Looking Glass: Ultrasound Imaging in the classroom to teach invivo Anatomy and Kinesiological Principles to first year Doctor of Physical Therapy students Ruth Maher, Sheri Hale Physical Therapy, Shenandoah University, Stephenson, VA, United States Objectives: To examine the effects of musculoskeletal ultrasound (MSK-US) demonstrations on students in-class experience and understanding of anatomy and kinesiological principles. Methods: A faculty member with MSK-US experience oriented students and identified structures. One demonstration covered the abdomino and lumbo-pelvic regions with students observing the superficial and deep abdominal muscles, mulitifidii, pelvic floor muscles, bladder and fascia at rest, during sit ups, core stability exercises, pelvic floor exercises, coughing, laughing and valsalva. A second demonstration observed the joint slide/glide associated with joint mobilizations which was quantified using on screen calipers. Students completed questionnaires anonymously via an online survey builder. A 5-point Likert scale graded responses which ranged from 5 (strongly agree) to 1 (strongly disagree). Results: 100% of respondents (79% response rate) agreed that MSK-US stimulated their interest, in addition to improving their knowledge and understanding. Furthermore, they gained a clinical perspective and synthesized what they were learning. Comments were extremely positive and included the following: MSK-US brought lecture to life.. added the missing piece of seeing and understanding’’, ‘‘ it’s one thing to be told what’s going on, another thing entirely to see it happen’’, ‘‘seeing.. inside the body’’, ‘‘it was beneficial to see the amount the shoulder moves during joint mobilizations and this is something I didn’t quite understand before the demonstration’’, ‘‘I liked that it was interactive’’ and ‘‘being able to visualize the difficulty in controlling pelvic floor and abdominal muscles’’. Conclusions: MSK-US is an invaluable and novel tool to use in the classroom. It provides real time static and dynamic views regarding how manual techniques and other factors such as posture, adipose and activities can affect muscle and joint function. It brings anatomy to life and underlines the clinical relevance of why the students are learning it. Students embrace it and are actively engaged in the classroom. Clearly ultrasound has applications beyond those of routine diagnoses.

2060747 Accuracy of Ultrasound in Fetal Birth Weight Estimation in Term Pregnancies Sadisu Maaji, Radiology, FMC BIRNIN KEBBI, Birnin Kebbi, Birnin Kebbi, Nigeria Objectives: The aim of this study is to determine the the accuracy of fetal birth weight estimation using ultrasonography Methods: This was a prospective study involving 109 singleton uncomplicated pregnancies. Inclusion criteria in the study were term pregnancy (36 to 42 weeks). Patients with malpresentation, gestational diabetes, pulmonary tuberculosis, multiple pregnancy were excluded. All examinations were performed using a Dynamic Imaging Concept D real time ultrasound machine with a 3.5 MHz curvilinear transducer. Measurements were made with calibrated caliper on the machine on frozen images. Data analysis was performed using SPSS 17.0 statistical soft ware after collation of data. Results: The mean maternal age was 2.246SD0.58 (range 20-40). The mean actual birth weight within the study cohort was 2.026SD0.49 (range of 2500-4000g).Twelve (10.7%) infants weighed less than 2500 g, and 83 (74.1%) weighed more than 2600 to 4000 g. Of the 109 14(12.5%) weighed more than 4500g.The mean estimated fetal weight was 2.026SD0.49 (range of 2500-4500g).The mean estimated

gestation age was 1.996SD0.166 (range 30-45). Table 3 show an overestimation of the fetal birth weight in 39.3%, while underestimation was seen in 53.6% of the fetuses. The accurate birth weight was seen in only 4.5% of the fetuses. Conclusions: There was significant error seen while estimating fetal weight by ultrasound and underestimation has the highest percentage. However for accurate detection of fetal weight scan delivery interval is the most important factor. Depending only on the fetal ultrasound for the estimation of fetal weight can lead to unnecessary obstetrical intervention.

2061652 Hepatic Size in Patients With Chronic Liver Disease Among Nigerian Population: The Sokoto Experience Sadisu Maaji,1 1 Radiology, UDUTH, Sokoto, Sokoto, Nigeria Objectives: The OBJECTIVES: of this study was to establish hepatic size in patients with clinical suspicion of chronic liver disease among Nigerian population. Methods: The study was carried out at the Gastroenterology unit of the department of Radiology Usmanu Danfodiyo University Teaching Hospital(UDUTH) Sokoto, Nigeria Approval for the study was obtained from the Ethics and Research committee of the UDUTH. A total of 61 patients with an initial diagnosis of CLD that were referred to the Radiology clinic were recruited. Results: A total of 61 abdominal ultrasounds were performed during this study period. All the cases met the inclusion criteria. The mean age was (46.0612.6) years (ranged 50 years).The mean liver size was (13.2561.48) cm (ranged 11 cm) and (14.00 60.77) cm (ranged 0.77 cm) for right and left lobe respectively. The Peak age of the patients was 50 years. Conclusions: The hepatic size among patients with chronic liver disease was documented Ultrasound is useful in the diagnosis of chronic liver disease in daily clinical practice. However, the sensitivity can be improved if a high frequency probe is used and done by experienced and dedicated operators.

2061655 Ultrasound Measurements of Renal Volume Among Nigerian Population Sadisu Maaji, Radiology, UDUTH, Sokoto, Sokoto, Nigeria Objectives: The aim of this study was to establish normal renal volume among our Nigerian population. Methods: All the patient’s blood pressure, serum creatinine and fasting blood sugar ware within normal range. There were 80 females and 24 males. Before proceeding to ultrasound scanning, the procedure was explained to the respondents and their consent obtained.All renal scans were done by using a single real-time Dynamic Ultrasound scanner using a 3.5-MHZ curvilinear probe. Hard copy images were taken for documentations and all the scans were done by a trained radiologist to avoid inter and intra observer variability. The renal volume of both kidneys was automatically generated by the machine using ellipsoid formula. Results: The mean age was 30.46SD19 years (18-70).The renal volume was 109.66SD29.3 and 119.76SD32.8 for right and left kidney
