Item Accidents during Transportation to School of Students in Bangkok Metropolitan Area(Vajira Medical Journal, 2009-12-30) Busaba Suppawattanabodee; Anan Manomaipiboon; Monawat Ngerncham; Premwadee KaruhadejAbstract Accidents during Transportation to School of Students in Bangkok Metropolitan Area Busaba Suppawattanabodee MSc (Biostatistic)* Anan Manomaipiboon MD, MSc (Clinical epidemiology)** Monawat Ngerncham MD, MPH (epidemiology)*** Premwadee Karuhadej Ed D**** * Clinical Epidemiology Unit, BMA Medical College and Vajira Hospital ** Department of Surgery, BMA Medical College and Vajira Hospital *** Department of Surgery, Siriraj Hospital **** Kuakarun Nursing College Objectives: To evaluate the incidence and types of accidents occurring to students in Bangkok Metropolitan area during their daily transportation back and forth to school. Study design: Descriptive study. Subjects: 17,499 students in kindergarten to Mattayom levels from 134 schools in Bangkok Metropolitan area were selected by multi-stage stratified random sampling. Methods: Data concerning the students' transportation including the accidents, occurring during the school year 2002 were collected by self-administered questionnaires which were answered by the students themselves or their parents. Main outcome measures: The number and percentage of accidents and the types of accidents during daily transportation of the students back and forth to schools. Results: 647 students (3.7%) experienced some accidents during their transportation while 388 students (2.2%) got injuries from the accidents. Most of the accidents occurred with the transportation by bus (23.3 %), public motorcycle (22.6%), and personal car (17.3 %). Types of accidents depended mainly on the types of transportation. The most common type of accident among all types of transportations was the collision between the vehicles. The second common type of accident was: falling off the cars among the students who traveled by public transportation of buses, cars or tricycles; falling over of the motorcycles among the students using motorcycles; and falling down or striking with the hard objects among the pedestrians. Conclusion: Though the number of accidents and injuries in the students' transportation were small, this problem created tremendous effects to the students, parents, school authorities, other people, and society. The majority of these accidents were from the drivers' behavior, lack of service mind of the personnel and partly from the suboptimal condition of the public transportation vehicles.

Study design: Prospective, randomized controlled trial. Subjects: A total of 56 female patients with breast cancer managed by modified radical mastectomy in BMA Medical College and Vajira Hospital during December 2004 to October 2005 were enrolled. They were divided into two groups. First, conventional dressing was applied in 29 patients as control group. Second, compressible brassiere without axillary compression was applied in 27 patients as study group. Methods: All subjects were randomly assigned into two groups after surgical wound closing. Surgeons and the patients never knew the dressing techniques until finishing the operation. Patients' characteristics, clinical data, intra-operative data and outcomes were collected and analysed. Main outcome measures: Occurrence of seroma, amount of drainage serum, length of hospital stay after operation and other post-operative wound complications. Results: Patients' characteristics, clinical data and intra-operative data were not different significantly between two groups. Amount of drainage serum, length of hospital stay and occurrence of seroma in control group and study group were 725.0 ± 511.6 ml vs 774.3 ± 535.6, 9.3 ± 5.4 days vs 11.1 ± 4.9 days and 4/29 vs 6/27 patients (p-value \> 0.05). These final outcomes were not different significantly too. Conclusion: Pressure dressing with compressible brassiere without axillary compression after modified radical mastectomy in breast cancer could not reduce seroma, drainage serum and length of hospital stay.

Methods: Two kinds of self-administered questionnaires, the first for general surgeons and the second for populations, were mailed to each group of the sample populations Main outcome measures: All types and numbers of gastrointestinal complications from ingested Santol seeds and behavior of Santol consumption. Results: 29.9% of general surgeons had experienced with gastrointestinal complications from ingested Santol seeds. From the year 2000-2002, there were 123 cases of these complications through out the country. The range of age was 20-84 year and the mean was 60.7 year. Perforation of distal part large intestine was the most common complication. For knowledge and behavior study, 94.6% of the sample populations ate Santol. 54.6% of the populations didn't know about these complications. In the populations who ate Santol, 41.2% ingested its seeds with the equal proportion between intentional and unintentional. Conclusion: Ingested Santol seeds can cause many kinds of gastrointestinal complications. The most common and severe complication was rectum and sigmoid colon perforation. Santol seeds are probably the most common foreign body that causes gastrointestinal complications especially rectum and sigmoid colon perforation in Thailand. Nowadays, a lot of peoples never knows about these severe complications and still ingests its seeds. Any public relations relations should be distributed for preventing these unexpected conditions. Key words: Gastrointestinal complications, Santol seeds Vajira Med J 2004 ; 48 : 1 - 10Item The Project of School Bus Safety in Bangkok Metropolis: Mode of Student Transportation(Vajira Medical Journal, 2010-01-13) Busaba Suppawattanabodee; Anan Manomaipiboon; Moanawt Ngerncham; Premwadee KaruhadejAbstract The Project of School Bus Safety in Bangkok Metropolis: Mode of Student Transportation Busaba Suppawattanabodee MSc (Biostatistic)* Anan Manomaipiboon MD, MSc (Clinical epidemiology)** Moanawt Ngerncham MD, MPH (Epidemiology)** Premwadee Karuhadej EdD*** * Clinical epidemiology unit, BMA Medical College and Vajira hospital ** Department of Surgery, BMA Medical College and Vajira Hospital *** Kuakarun Nursing College Objective: To identify the modes of student transportation in Bangkok Metropolis.

Subjects: Two hundred and nineteen patients in two tertiary care hospitals - BMA Medical College and Vajira Hospital and Phrapinklao Hospital were enrolled in this study during June 2002 to March 2003, 73 patients as cases and 146 patients as controls. Cases were defined as newly diagnosed inguinal hernia in adult male with the duration of symptoms less than one year. The corrected diagnoses were confirmed from operative report. Previously surgical repairs of inguinal hernia were excluded. Controls were male in-patients during the same periods as cases. Controls were approximately age-matched within five years interval to cases. In-patients with urological, colo-rectal and cardio-thoracic diseases were not recruited as controls. Methods: Both cases and controls were asked to answer the same questions on their demographic background, past history of heavy object lifting, smoking, urinary outflow tract obstruction, constipation, chronic cough. Their height and estimated body weights before occurrence of the diseases and previous appendectomy via right lower abdominal incision were recorded. Results: In univariate and multivariate analysis, no association between all exposure variables and inguinal hernia were found. The adjusted odds ratio for inguinal hernia in relation to past history of heavy object lifting was 1.1 (95% CI, 0.6-2.2). The adjusted odds ratio in relation to smoking, increased intra-abdominal pressure, previous appendectomy and obesity were 1.0 (95% CI, 0.6-1.9), 1.1 (95% CI, 0.6-1.9), 1.3 (95% CI, 0.4-3.7) and 0.7 (95% CI, 0.3-1.3) respectivel Conclusion: This study did not suggest an inverse effect between past history of heavy object lifting, smoking, urinary outflow tract obstruction, constipation, chronic cough, previous appendectomy and inguinal hernia.
