ABSTRACT
Objective : To study the usage of transrectal ultrasonographyDesign: Prospective, descriptive studySetting : Ultrasonography room and Surgical OPD, Srinagarind hosptial, of Medicine, Khon Kaen UniversitySubjects : Patients who had problem of prostate gland between November 1997 and September 1998Data collection : Protocol Measurement : Descriptive statistics, including number, means, and percentagesResults : There were 34 patients. Their age ranged from 29 to 85 years (means 59.48 years). Ultrasonography Diagnoses were the same as the clinical diagnoses in every case. Most ultrasonography diagnoses were similar to final diagnoses, except 4 cases. Instead of BPH, one case was prostatic abscess, two cases were prostatitis, and the last was prostatic cancer.Conclusions: Transrectal ultrasonography had high efficiency to examine the pelvic organs, esp. prostate gland. Instead of blind biopsy, trransrectal ultrasonography provided visual biopsy of prostate gland.Keywords: (1) Transrectal (2) Ultrasonography
ABSTRACT
Background : The incidence of osteoporotic hip fracture increases annually, the key to successful treatment of osteoporosis is early diagnosis and treatment before fracture. The Singh index was a popular tool for diagnosis of osteoporosis in the past, but its reliability is debated.Objective : To evaluate the intra- and inter-personal reliability of Singh grading among elderly Thai women between two radiologists at Srinagarind hospital, Khon Kaen University, Thailand.Design : Cross-sectional descriptive studySetting : Thai elderly women in Khon Kane province, Thailand.Outcome Measurements: Singh grading, intra- and inter-observer reliability by kappa (k) and weighted-kResults :We registered 130 elderly Thai women in the study. The age of participants averaged 71.6 years (range 61-86 years). The first and second intra-observer (and their weighted) reliability k was 0.15 (95%CI: 0.04-0.26) (and 0.27), and 0.29 (95%CI: 0.15-0.42) (and 0.35), respectively. The inter-observer (and weighted) reliability kwas 0.10 (95%CI: 0.00-0.20) and 0.26. Conclusion : The intra- and inter-person reliability of the Singh index is poor; therefore, the index needs to be simplified to establish its reliability as a screening tool for osteoporosis. Key word : Singh index, Kappa (k), Reliability, Osteoporosis
ABSTRACT
Background: Computed tomography (CT scan) is a common radiological practice; however, among pre-school-age children, it can be a fearful experience, so much so that non-cooperation of children may result in failure to get any useable results. Psychological preparation can be used to reduce the level of fear in children.Objective: To compare the level of apprehension among preschoolers undergoing CT scan, given psychological preparation vs. the normal clinical explanation.Design: Quasi-experimental researchSetting: Srinagarind Hospital, Khon Kaen University, ThailandPopulation and Samples: Data were collected on the responses of 60 children between four to six years of age undergoing CT for the first time. Two groups (normal and experimental) were formed by a simple random, age matching method.Intervention: Psychological preparation included being read a story called ‘C.T. the Magic Camera and the Kid’ created by our research team.Measurements: Data were collected on the fear responses of the children undergoing CT and analyzed by t test.Results: Subjects in the psychologically-prepared group exhibited significantly (p \< 0.05) less apprehension than those in the control group.Conclusions: The findings suggest some psychological preparation is needed before children undergo CT scan or any other invasive procedure (such as spinal puncture or intravenous fluid administration).
ABSTRACT
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.
ABSTRACT
Background: The use of non – ionic contrast media is favored by many imaging modalities because, supposedly, it has putatively fewer complication.Objective: To study risk factors that are associated with allergic reaction to non – ionic contrast media in patients undergoing chest or abdominal computed tomography.Design: Descriptive study.Setting: Diagnostic Radiology Unit, Srinagarind Hospital, Faculty of Medicine,Khon Kaen University.Intervention: Prospective study between December 2001 and May 2002 of 1,064 patients undergoing chest or abdominal computed tomography (CT) and receiving intravenous, non- ionic contrast media Iopamidol 300 or Iopromide 300 .Measurement: Adverse effect during administration of any non- ionic intravenous contrast media.Result: No statistically significant difference was found between the kind of media, amount or method of injection of either non –ionic contrast media ( p =0.298, 0.082 and 0.911). No statistically significant adverse affect was found related to any underlying disease i.e. heart disease (37/1,064), allergy (58/1,064), asthma (31/1,064), hypertension (95/1,064), and diabetes mellitus (89/1,064) (p= 0.423, 0.846, 0.299, 0.955, 0.620, respectively) except a history of seafood allergy ( p \< 0.05).Conclusion: A history of seafood allergy is the only risk factor associated with allergic reaction to the non- ionic contrast media.
