Ibuprofen versus acetaminophen for the relief of perineal pain after childbirth: a randomized controlled trial.

OBJECTIVES: To evaluate efficacy of ibuprofen compared with acetaminophen for relief of perineal pain after childbirth, side effects of ibuprofen compared with acetaminophen and patient satisfaction in treatment between the 2 groups. MATERIAL AND METHOD: A total of 210 women who gave birth by spontaneous vaginal delivery with mediolateral episiotomy between June 2006 and November 2006 were randomly assigned to receive either ibuprofen (400 mg) (n = 106) or acetaminophen (1000 mg) (n = 104), both given orally when suturing was completed. Pain ratings were recorded before the treatment and at 1, 2, 3 and 4 hours after the treatment on a 10-cm visual analogue scale. Side effects and patient satisfaction were assessed at 24 hours. RESULTS: Pain in the ibuprofen group was considerably more reduced than the acetaminophen group at 1 hour of treatment (mean pain rating 2.18 vs. 2.88, respectively; p < 0.003). Even though, at 2, 3 and 4 hours of treatment ibuprofen seemed to give more reliefof pain than acetaminophen, they did not reach statistically significant differences (mean pain rating; at 2 hour: 1.59 vs. 1.97, p = 0.093; at 3 hour: 1.08 vs. 1.31, p = 0.183; and at 4 hour: 0.69 vs. 0.85, p = 0.169; respectively). There were no side effects and no significant differences in overall patient satisfaction between the two groups. CONCLUSION: Ibuprofen was consistently better than acetaminophen at 1 hour after treatment for relief of perineal pain after childbirth without any side effects. After 2 hours, ibuprofen and acetaminophen had similar analgesic properties.

Research publication by the Royal Thai College of Obstetricians and Gynecologists residency training program, 1994-2003.

OBJECTIVE: To evaluate the impact of the manuscript requirement policy on research publications from the Royal Thai College of Obstetricians and Gynecologists (RTCOG) residency training program. MATERIAL AND METHOD: Names and research titles of RTCOG residents from 1994 to 2003 were used to search for publications in the Medline system and Thai Index Medicus. RESULTS: There were 759 residents with 188 (24.8%) articles published. The publications per year varied from 4.8% to 17.0%. Residents were the first authors of 75 articles (39.9%). One hundred and thirteen articles (60.11%) were published in local medical journals. The majority of articles published in international journals (65.3%) were published in the Journal of the Medical Association of Thailand. After initiation of the publication promotion policy in 1999, the number of publications in which residents were not the first authors increased from 39.8% to 60.2%. CONCLUSION: The manuscript requirement policy can maintain the research publication rate.

The location of needle insertion effect on maternal pain in amniocentesis.

OBJECTIVE: The purpose of this study was to determine whether maternal pain in amniocentesis was associated with the location of needle insertion and other identifiable clinical correlates. MATERIAL AND METHOD: This prospective study of mid-trimester amniocentesis was conducted between October 2005 and December 2005. Women were asked to complete a visual analog scale (VAS) after the amniocentesis. The distance from uterine fundus to symphysis pubis and from the location of needle insertion to symphysis pubis were measured and calculated to divide the insertion into two groups: upper third and middle third. The effect of previous amniocentesis, previous abdominal surgery, needle insertion through placenta and operators' experience was determined. The t-test was used for analysis; a probability value of < 0.05 was considered significant. RESULTS: Seventy-two women were participated in the study. The mean VAS was 2.7 +/- 2.1. The perception of pain was significantly less in patients with the upper-third insertion as compared with the middle third insertion (VAS 2.2 vs 3.9, p = 0.002). Previous amniocentesis, previous abdominal surgery, needle insertion through placenta and operators' experience had no impact on pain intensity. CONCLUSION: The pain from amniocentesis was significantly less in the patients with the needle insertion in the upper third of the uterus.

A comparative study of early postoperative feeding versus conventional feeding for patients undergoing cesarean section; a randomized controlled trial.

OBJECTIVE: To compare the efficacy and side effects of early postoperative feeding versus conventional feeding for patients undergoing cesarean section. MATERIAL AND METHOD: Women undertaking uncomplicated cesarean section under regional anesthesia were randomly assigned to early feeding or conventional feeding groups. Early-fed women were offered a liquid diet within 8 hours after surgery, advanced to a soft diet on the next meal and then a regular diet. Conventional-fed women were prohibited from mouth-fed for the first 24 hours after surgery, advanced to a liquid diet on the first postoperative day, and then a soft diet on the second postoperative day. RESULTS: Two hundred patients were enrolled in the study; 107 patients were assigned to the early feeding group and 93 patients to the conventional feeding group. There were no significant differences in the demographic data between the two groups. In all cases, consistent anesthetic method was applied with no intraoperative adhesion and no post operative complications were observed. The rate of mild ileus symptoms in the early feeding group was significantly less than the conventional group (19.6% versus 31.1%, p = 0.03). The early feeding group also had significantly shorter time interval to bowel movement (16.7 hours versus 25.3 hours, p < 0.001), duration of intravenous fluid administration (20.5 hours versus 24.8 hours, p < 0.001), and overall length of hospital stays (3.3 days versus 4.0 days, p < 0.001). CONCLUSION: The study results indicated that the early feeding after uncomplicated cesarean section had reduced the rate of ileus symptoms and offer potential benefits associated with shorter interval to bowel movement, intravenous fluid administration, and length of hospital stays. However, management of postoperative feeding requires proper counseling on details of both regimens and flexibilities should be provided to accommodate early feeding when requested by the patients.

Future cancer management with stem cell knowledge and technology.

Cancer has been proposed as a result of abnormal control of growth and development of stem cells for more than century. This is the "cancer stem cell hypothesis". Both cancer and stem cells share many common especial properties. They are immortal and have good differentiation potential. In addition, organogenesis and carcinogenesis are very similar processes. Recently, more evidence and convincing data from stem cell biology research are supporting this concept. Furthermore, the research provides new promising approaches for cancer diagnosis and treatment based on stem cell knowledge and technology. Upcoming data and evidence may revolutionize cancer management, making it more effective and safer.

Nasal bone hypoplasia in trisomy 21 at 15 to 24 weeks' gestation in A high risk Thai population.

OBJECTIVE: To assess the utility of nasal bone hypoplasia in the detection of fetuses with trisomy 21 in the second trimester in a high risk Thai population. MATERIAL AND METHOD: A prospective study involving pregnant women undergoing amniocentesis due to increased risk of aneuploidy from January 2005 to December 2005. Fetal biometry and nasal bone measurements were obtained at the time of amniocentesis. Linear regression model and diagnostic tests were analyzed using the SPSS computer program. RESULTS: A total of 407 fetuses were evaluated. In euploid fetuses, the Nasal Bone Length (NBL) increased linearly with advancing gestational age. Fetuses with Down syndrome had a significantly higher proportion of NBL below the 5th centile when compared with normal fetuses (p < 0.05). The optimal nasal bone threshold associated with trisomy 21 is a BiParietal Diameter/Nasal Bone Length (BPD/NBL) ratio of 10 or greater, yielded a sensitivity of 80%, specificity of 86% for detection of trisomy 21. CONCLUSION: Nasal bone hypoplasia is associated with an increased risk of Down syndrome in the presented population.

Conventional and novel methods for embryonic stem cell line derivation.

Cell therapy is the promising therapeutic tool for the next decade. "Regenerative Medicine" based on cell and tissue replacement therapy is proposed as a revolutionary approach to various chronic and incurable conditions. The first key step for successful cell therapy is the establishment of clinical grade human Embryonic Stem Cell (hESC) lines. This article provides a concise summary on conventional and novel methods for hESC line derivation. There is also discussion on progression, future direction and problems in hESC line development. In Thailand, more advance knowledge, skill, and technology are required to develop the first human embryonic stem cell line and step forward to make cell therapy a reality.

Cell therapy: hype or hope.

Cell therapy is a promising therapeutic tool for the next decade. It has a potential to cure a number of chronic diseases and conditions related to aging processes or degenerative changes. In addition, it could be used to replace cells and tissues in injured organs. Furthermore, it may provide a novel approach to congenital anomalies and genetic disorders where current therapeutic options are limited However, many crucial questions need answers to ensure a safe, effective and successful solution in the field of cell therapy. In Thailand, innovative knowledge and expertise in stem cell biology and technology are required as the key elements to make cell therapy a "real" hope.

International stem cell research; networking and collaboration.

Stem cell research has obtained more attention during the last decade because of its strong potential as a new tool to cure many chronic diseases. In addition, stem cell knowledge is an important basis for understanding pathophysiology at the cellular level and developing disease models for experimental research. There are different limitations on resources, budget, policy and regulation among countries. As a result, each country has particular advantages and disadvantages in stem cell research. This result in the establishment of international networks and collaborations to coordinate and promote stem cell research aimed at medical applications.

Introduction to stem cell medicine.

Embryonic stem cell is the promising novel therapeutic tool for various degenerative diseases and tissue injuries. With the concept of cell and tissue therapy, many chronic disorders will be curable. The present article provides basic knowledge of stem cell in areas of definition, classification and future clinical applications. In addition, stem cell application is not only focusing on regenerative purpose, but also concentrating on more understanding about the early human development and the pathophysiology of genetic diseases at the cellular level. However, there are some technical problems and ethical concern that should be resolved before applying stem cells into clinical practice.

Ethics and the comprehensive application of epistemology in medical practice.

Our simple definition of ethics is good thought, speak and action. Epistemology means the hypothesis of facts about thought, speech and action. Medical practice is all means of medicine. Medicine classifies people into normal and abnormal. The abnormal are the sick. They loose some organs or those normal looking organs are dysfunctional. They are social problems, some can be treated, and some do not get the appropriate care. The problems of society of normal people are overeating and obesity, abortion, drug abuse, promiscuity, torture, terrorism, disobeying rules and order, corruption, brain-washing and unethical advertisements, etc. On the other hand, the social problems of the abnormal are down, deafness, blindness, dumb, hypertension, hypercholesterolemia, diabetes mellitus and cancer, etc. An example of the social-doctor problem is the mal distribution of doctors in rural areas. It was reported by the ministry of public health that the ratio of doctor to population to be 1:800 in Bangkok and 1:5, 700 in some rural areas in the north eastern part of Thailand. The doctors, themselves, are at a high grade of worker and intelligent quotient. They know all the problem and, at the same time, create problems, both, faster than the general population can do. It affects good and bad in the society. In the past, present and the foreseeable future the medical students get their studies in the western style. Their medical schools are situated in big cities. These schools are old and famous. They learn their medical procedure in a big hospital of more than 400 beds in the inpatient department wards. Their instructors and professors are highly qualified, are middle class people and well accepted in the society. Their families are lovely and warm. Their children study in the first class schools in town. The medical students feel very happy and appreciate seeing their professors in television routinely at prime time. In conclusion, their professors are an example of role model for them to follow. Everyone looks for security in her/his profession. Facts need no proof and reference. People with justice in mind should believe and understand the above mentioned. This leads to the problem of mal distribution of doctors in rural areas, why do doctors live in big cities or wish to be in the private sector? In fact, not many a number of doctors serve in the rural area. About 4-5 of them, their name will be announced yearly as the best rural doctor award. After the big ceremony, lasted not longer than a month, it is hard to remember their name. They are proud to be praised, it pushes them into stress intentionally with all the best of their intelligence and the total of their body strength to work harder in rural. Unfortunately their earning, the security of their profession, the increased chance of being sued, to get caught in the medical litigation, the expenses of their family social status and the study of their children cannot be compared to of those doctors in big city and/or in the private sector. Mal distribution of doctors in remote rural areas has been a persisting unresolved problem in many parts of the world, why not apply the principles of ethics and epistemology? They have been left, untouched forever.

A comparison of vaginal misoprostol 800 microg versus 400 microg for anembryonic pregnancy: a randomized comparative trial.

OBJECTIVE: To compare the efficacy, side effects and patient satisfaction between 800 microg versus 400 microg intravaginal misoprostol for anembryonic pregnancy. MATERIAL AND METHOD: Women who had diagnosed as anembryonic pregnancy were treated as IPD case and randomly assigned to receive either 800 microg or 400 microg intravaginal misoprostol. The second dose was administered in the equal dose if there was no evidence of abortion in 24 hr. The treatment failure was determined by no complete abortion within 48 hr. If spontaneous abortion had not occurred, or had heavy vaginal bleeding or evidence of incomplete abortion either by clinical manifestation or sonographic finding then dilatation and curettage was performed. RESULTS: Fifty patients were enrolled into the study, 25 patients were randomized to receive 800 mg and 25 patients were received 400 mg intravaginal misoprostol. Complete abortion within 48 hr was not different between the 2 groups (72%). However complete abortion within 12 hr was significantly higher in the 800 mg group than in the 400 mg group (64% versus 20%, respectively, p = 0.016). The median time to abortion in the 800 mg group was significantly shorter than in the 400 mg group (9.0 hr versus 16.0 hr, respectively, p = 0.01). There was no significant difference in the side effects and patients' satisfaction between both groups. CONCLUSION: Vaginal misoprostol can be used for termination of pregnancy in case of anembryonic pregnancy with high successful rate of complete abortion and no serious adverse effects. We recommend the 800 microg vaginal misoprostol regimen because within 12 hr the complete abortion rate was higher and the median time to abortion was shorter than the 400 microg regimen with no difference in side effects. This may decrease the suffering time of both physical and psychological trauma to the patient before complete abortion has occurred.
