Ultrasounoraphic Findings in Gastrointestinal Pathology

 Utrasonographic  features  of  32  patients  who  had  gastrointestinal  pathology  proved  by  endoscopy  and / or  exploratory  loporotomy  with  pathological  sections  were  analysed.  The  pathology  was  classified  into  neoplasm  group  (17 / 32) and  non – neoplasm  group  (15 / 32).  Among  17  cases  of  neoplasm  group,  echoic  masses  were  found  in  9  cases  (9 /17),  thicken  bowel  wall  in  7  cases  (7 /17)  which  all  are  adenocarcinoma  of  stomach  and  mixed  echoic  mass in  only  I  case  (1/17).  In  non – neoplasm  group,  we  found  gastric  outlet  obstruction  or  dissented  stomach  without  mass  5  cases  ( 5 /15),  mixed  echoic  mass  4  cases (4 /15),  echoic  mass  2  cases  ( 2 /15),  thicken  bowel  wall  2  cases  ( 2 /15),  pseudokidney  sign  1  case  and  matted  fluid – filled  bowel  loops  1  case.  We found  hat  most  cases  of  the  neoplasm  group  have  echoic  mass  and  thicken  bowel  wall  (16 /17).  The  variation  in  sonographic  findings  in  non – neoplasm  group  depended  on  pathological  process  of  the  diseases  as  discussed  in  detail  in  the  text.  

Intussusception in Srinagarind Hospital : A review of six-year period

At Srinagarind Hospital , from January 1982 to January 1988, 34 case of intussusception were studied retrospectively . Barium enema reduction were performed in 19 intussusceptions and were successful  in 6 cases or 31.58% There were 3 recurrences. Repeat hydrostatic reduction was successful in one and failed in two cases. The later two cases needed a surgical intervention and leading points were noted. Colonic perforation occurred in 6 cases. One case occurred during barium enema reduction on the third trial and leading point was noted at operation. Factor which influenced failure of the hydrostatic reduction included long duration of illness, presented of leading point and underlying colonic pathology in old age. Clinical evidence of intestinal perforation (peritonitis) or free intraperitoneal air on abdominal radiographs was the only absulute contraindication to the administration of barium enema to the patient suspected of intussusception.

Radiation Hazard from Portable X-ray Unit

 Using the survery meter calibrated by RPS, the measurement of X-ray dose contributed from the portable X-ray unit in Srinagarind Hospital Wards is performed. The data obtained is relatively advantageous for radiation safety measures, since it denotes the level of radiation dose recelived by staff workers and the maximum workload per day which should be kept to safety limit

Postero-anterior Pressure Technique for Lubar Intervertebral Disc Herniation

Background : Physical therapy treatment is one of the treatment used for the management of lumbar disc herniation and become more popular during resent years. Loss of function of lumbar spine is an essential problem for the back pain patient. Manual therapists sometimes select the technique of postero-anterior pressure (PA) to gain range in lumbar movements.Objectives : To measure the effect of postero-anterior pressure technique on lumbar spine movement in lumbar disc herniationDesign : An experimental studySetting : Srinagarind Hospital, Faculty of Medicine, Khon Kaen UniversitySubjects and Methods : Forty patients who were diagnosed with lumbar disc herniation by Orthopaedics and Radiologists. Magnetic resonance imaging (MRI) was used to a gold standard for diagnoses. Subjects were randomly assigned to a treatment or control group. The treatment group received both the lumbar traction and the postero-anterior pressures technique. The control group received only the lumbar traction.Measurements : The measurements consists of pain scale using the visual analogue, trunk movement and straight leg raising (SLR) using the inclinometer.Results : A Mann-Whitney U-test and Generalized Estimating Equation (GEE) revealed no significant difference between groups in the pain level. A repeated measure ANOVA no showed no significant difference between groups both trunk movements and SLR degrees. Even though, the results of the pain scale, the trunk movements and the SLR in the treatment group were not found to be significant difference from the control group but there were a tendency.Conclusion : This study is the first study providing support for the use of postero-anterior

Formative evaluation for the fifth year medical student in clinical radiology by pre-test and post test

Background: Evaluation is one of the essential parts of education.  Before the academic year 2003, only final examination was used to evaluate students’ knowledge in Department of Radiology, Faculty of Medicine, Khon Kaen University.Objective: To compare students’ knowledge in diagnostic radiology between pre- and post-learning periods.Subject and Method: All the fifth-year medical students in the academic year 2003 were divided into 12 groups (10-15 per group), total 156 students.  Each group rotated to attend in diagnostic radiology for 2 weeks.  Each student was evaluated by pre- and post-tests which were the same test.Result: One hundred and fifty-two students (97.43%) showed improvement in their knowledge.  The average score of the pre-test was 6.8, while that of the post-test was 10.91.  There was no relationship between the score and final grade, except 4 students who got same score from the tests.  They also got low score from the final examination, both theory and practice sections.Conclusion: Students had more knowledge in diagnostic radiology after learning.
