ABSTRACT: Objectives: To evaluate the frequency of cytohistologic discrepancy of high-grade squamous intraepithelial lesions (HSILs) in Pap smears and associated factors. Methods: Medical records of 223 women with HSIL Pap smears who were treated at Thammasat University Hospital were reviewed. Data on age, parity, menopausal status, contraceptive use and colposcopic directed biopsy and loop electrosurgical excision procedure (LEEP) pathology results were recorded. Results: Mean (SD) age of patients was 38.0 (9.4) years. The majority were premenopausal (86.5%) and multiparous (83.9%). Cytohistologic discrepancy between the Pap test and colposcopic-directed biopsy histology was 45.7% and that between the Pap test and LEEP histology was 29.5%. Fifty-four (24.2%) women had no high-grade CIN on both colposcopic directed biopsy and LEEP. Nulliparity, postmenopausal status and having no oral contraceptive pills use were factors associated with cytohistologic discrepancy. Conclusion: The exact cytohistologic discrepancy rate was relatively high (24.2%). Factors associated with cytohistologic discrepancy were nulliparity and postmenopausal status and having no oral contraceptive pill use.

ABSTRACT: To determine the major-complication rate of gynecological laparoscopy in Police General Hospital.
A retrospective and descriptive analysis of medical records from 423 women who underwent gynecological laparoscopy in Police General Hospital was conducted.
Four hundred twenty three women were recruited between January 2007 and December 2010. One-third of subjects had history of previous gynecological surgery. Major complication rate was 2.84% (12/423). Urinary bladder, ureter, bowel, and vesico-vaginal fistula injury were 0.95% (4), 0.71% (3), 0.95% (4), and 0.23% (1), respectively. The conversion rate to exploratory laparotomy was 4.7% (20). There was no death in subject who had serious complication in this study. The operative time trended to decline in minor operation but not changed in major and advanced operation. Two-third of major complication was intraoperative diagnosed and repaired.
The major complication rate was 2.84%. The urologic and bowel injury are the common complications.

ABSTRACT: The aim of the present study was to evaluate the prevalence of abnormal Pap smears as detected by liquid-based (LBP) and conventional (CPP) techniques in women who were patients in the gynecologic clinic, Thammasat University Hospital.
Retrospective analysis of cervical cancer screening, histopathological findings and operative procedures was done between January 2009 and December 2009. Of the 6,332 participants who underwent gynecological examination and cervical screening and had a Pap smear result as atypical squamous cells of undetermined significance or worse would be performed a further colposcopic examination.
A total of 6,332 women were screened for cervical cancer in the one year period. A total of 169 abnormal Pap smears were found. Of 497 (8%) and 5,835 (92%) women were screened by LBP and CPP, respectively. The mean age of patients was 39.45 years old (14-90) and 1,550 (24.5%) women were post menopausal. The Prevalence of abnormal Pap smears was 4.0 and 2.6% in the LBP and CPP groups, respectively. Among LBP group, patients with atypical smear and LSIL (low grade squamous intraepithelial lesion) were 11 (2.29%) and 9 (1.8%), respectively. While CPP group, patient with atypical smear, LSIL, HSIL (high grade squamous intraepithelial lesion) and cancer were 73 (1.25%), 49 (0.84%), 25 (0.43%) and 2 (0.03%), respectively.
The prevalence of abnormal Pap smear in women who attended gynecologic clinic of Thammasat University Hospital was 4.0% and 2.6 % per LBP and CPP group, respectively. There was no significant difference in the incidence of atypical smear and false positive result between LBP and CPP.

ABSTRACT: Several adjuvant analgesic agents proposed to treat the postoperative pain while reducing the doses of opioid and its derivatives. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in several operative procedures. The present study aimed to demonstrate the morphine-sparing effects of single-dose intramuscular diclofenac sodium in explore laparotomy gynecologic surgery.
Forty-six patients were randomly assigned to receive 75-mg of diclofenac sodium or normal saline with intramuscular morphine during immediate postoperative period. Additional morphine for pain control was given by patient-controlled analgesia. 24-hour morphine consumption, pain score, adverse effects and satisfaction of the patients were recorded.
Median morphine consumption among groups was significant difference between placebo and diclofenac group (32 and 19 mg) (p = 0.041). Greater difference was shown in patients who underwent total abdominal hysterectomy (p = 0.009). Catagorical pain score at 6-hour postoperatively was significant lower in diclofenac group (p = 0.006). No significant difference was found between groups in visual analogue pain score, patients' satisfaction, presence of bleeding or nausea and vomiting.
The present study demonstrated that single dose of diclofenac sodium has morphine-sparing effects and can be safely used in explore laparotomy gynecologic surgery without significant adverse effects.

ABSTRACT: A case of well differentiated endometriod adenocarcinoma of the endometrium with a synchronous endometriod and clear cell adenocarcinoma of both ovaries was reported. Recently, a 28-year-old woman presented with vaginal bleeding was diagnosed to have only FIGO stage IaG1 (FIGO 2000) cancer of the endometrium. After 3 months of high dose progestin treatment, 15 cm bilateral ovarian tumors later diagnosed as FIGO stage IIIa ovarian cancer (mixed endometriod and clear cell adenocarcinoma) were detected, and later surgically removed. The patient then was started on Placitaxel/Carboplatin combination chemotherapy for 6 cycles after surgery. The synchronous cancers of endometrium and ovary are usually presented in woman with median age of 50 with obesity, diabetes, and hypertension. These low grade tumors and better prognosis are the norm in contrast to the authors' case with clear cell component and higher stage of ovarian cancer in young lean Thai woman.

ABSTRACT: To determine the prevalence of abnormal cervical cytology by liquid based cytology (LBC) in pregnant women who attended the antenatal care clinic at Thammasat University Hospital.
LBC was performed on specimens from the collecting vial containing preserved cell solution (Cytyc, Boxborough, MA) in pregnant women who attended antenatal care at the antenatal care clinic, Thammasat University Hospital between March and July 2010. One hundred forty three pregnant women were recruited in the present study. All cytological reports were reviewed by senior cytopathologists for accurate diagnosis using the Bethesda System 2001 criteria. Patients with abnormal results as "abnormal squamous/glandular cells of undetermined significant" or more over were referred for colposcopic examination.
One hundred forty three pregnant women participated in the present study. The average age was 27.09 years. There were 10 abnormal Pap smear results with four, five, and one cases of ASC-US, LSIL and HSIL respectively The prevalence of abnormal cervical cytology in this investigation was 7% with 0.7% high-grade cervical intraepithelial neoplacia. Only 6% of participants had the correct understanding of the necessity of Pap smear testing. Thirty-one percent of multiparous pregnant women in the present study had no previous Pap smear screening. The majority of participants had coitarche before the age of 20.
The prevalence of abnormal cervical cytology in pregnant patients attending the antenatal care clinic at Thammasat University Hospital was 7%. The cervical cytology and related education were highly recommended in antenatal care clinic to increase cervical cancer screening coverage among reproductive age women.

ABSTRACT: To determine risk factors of high-grade cervical intraepithelial neoplasia (CIN 2-3) among women with atypical squamous cells of undetermined significance (ASC-US) Papanicolaou (Pap) smears.
Two-hundred and sixty-six women with ASC-US Pap tests who underwent a colposcopy with histologic study were enrolled between August 2008 and June 2010. Patient data including age, education, income, parity, current pills used, number of vaginal deliveries, number of sexual partners, age at first sexual intercourse, history of sexually transmitted diseases, history of pelvic inflammatory disease and smoking habits were obtained. Logistic regression analysis was used to evaluate factors associated with CIN 2-3.
CIN was diagnosed in 134 of 266 women (50.4%). Ninty-seven of these (72.4%) had CIN 1 and 37 (27.6%) had CIN 2-3. Frequency of the latter was lower in women who had at least bachelor's degree graduation as compared to those having less than primary school graduation (odds ratio (OR) 0.085, 95% confidence interval (CI) 0.013-0.557). In addition, those with a higher income (5,000-20,000 baht per month) had less frequent CIN 2-3 (OR 0.378, 95% CI 0.147-0.970), whereas women who had 3 or more sexual partners were more likely to develop CIN 2-3 (OR 3.181, 95% CI 1.316-7.687).
Women with ASC-US Pap smears who had 3 or more sexual partners, low education and low income were at an increased risk of CIN 2-3. Therefore, this group of patients deserve a high priority for immediate colposcopy in order for early detection of high-grade CIN.

ABSTRACT: Most Thai people believe that health care providers have a lower risk of any disease than their patients. This belief may lull Thai health care providers into accepting the false belief that they are at a lower risk of having the precancerous conditions that lead to cervical cancer.
This study compares the prevalence of abnormal Pap smears from health care providers (HC) and non health care providers (NHC) by using the standard liquid-based Pap smear processing at Thammasat University Hospital's pathology department, Thailand.
Both health care providers (HC) and non health care providers (NHC) were patients at the outpatient clinic, Thammasat University Hospital. They were screened for cervical cancer by using liquid-based Pap smear (LBP). Cytological diagnoses and specimen adequacy were classified using the Bethesda system 2001. All subjects who had abnormal cytology more than atypical squamous cells or atypical glandular cells were counseled to have performed a colposcopic directed biopsy for confirmation of pathology.
A total of 250 liquid-base Pap smears were processed and evaluated at the Gynecology clinic, Thammasat University Hospital from April 2008 to May 2008.
The groups of HC and NHC consisted of 122 and 128 women, respectively. In general, both the HC and NHC groups were similar in their age, religion, income and education level distributions. The range of ages was between 16 and 75 years, with the mean age equal to 40.2 +/- 10.5 years. Prevalence of abnormal Pap smears was 9.8% in HC and 9.4% in NHC (p-value = 0.90). HC showed atypical change (ASC, AGC), low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) at 0.8%, 1.6% and 7.4%, respectively. NHC had an incidence of atypical change, LSIL and HSIL at 0.8%, 0.8% and 7.8%. HC had an equal incidence of abnormal Pap smears prevalence to NHC. Further, the percentage of HC and NHC groups with histological confirmed cervical intraepithelial neoplasia (CIN) 1 were not significantly different (4.92% vs. 6.25%, p-value = 0.70), likewise CIN 2/3 (1.64% vs. 1.56%, p-value = 1.00). According to our study the rate of abnormal Pap smears observed in both health care providers and clients was essentially the same.
The prevalence of abnormal Pap smears in health care providers was statistically equivalent to that in their clients.

ABSTRACT: To determine the value of transvaginal color Doppler study of uterine artery and investigate the differences in blood flow of uterine artery among women with chronic pelvic pain (CPP).
A total of 50 female patients were recruited. The study group consisted of 25 women with CPP of possible gynecological origin. Twenty-five women without CPP made a control group. All women were examined using transvaginal color Doppler ultrasonogram after negative finding of pelvic examination. The mean pulsality index (PI) and resistant index (RI) of the uterine arteries were recorded and compared.
The mean ages were 36.6 ± 10.6 and 32.0 ± 6.7 years in the study group and control group, respectively. The duration of pain ranges from 6-48 months (mean, 14.8). The mean PI and RI values of the uterine arteries in patients with CPP were significantly lower than in the control group; PI = 2.12 ± 0.78, 2.76 ± 0.84 and RI = 0.79 ± 0.19, 0.89 ± 0.05, respectively (P < 0.05).
Doppler flow indices demonstrated significant increase of uterine arteries vascularization in CPP women related to pelvic causes. Transvaginal ultrasound with noninvasive Doppler study could be a useful primary investigation for CPP women, especially when financial resource is an issue.

ABSTRACT: To study the accuracy of self vaginal douching and collection for HPV types 16, 18, 31 and 33 in women visiting Thammasat Hospital for the explicit purpose of cervical screening.
A pelvic examination and Pap smear were performed for all women who came for cervical screening. Specimens were also collected by self vaginal douching before cervical screening and sent to the cell and molecular biology laboratory for analysis of human papillomavirus (HPV) types 16, 18, 31 and 33 using the polymerase chain reaction (PCR).
HPV prevalence was 3.6% overall from 250 women in this study. Twenty-four (9.6%) women had an abnormal cytology screening result. No cancer was found. Four women had a high grade squamous intraepithelial lesion (HSIL) and 14 had a low grade squamous intraepithelial lesion (LSIL) from colposcopic biopsy. Self vaginal douching for HPV 16, 18, 31 and 33 was used to predict abnormal Pap smear. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 12.5%, 97.5%, 33.3% and 91.3%, respectively.
From our analysis of self-vaginal douching for HPV detection using cases from Thammasat university hospital, it cannot replace the Pap smear.

ABSTRACT: To study the prevalence of high-risk human papillomavirus (HPV) types 16, 18, 31 and 33 in healthy Thai women using polymerase chain reaction (PCR) technique.
Two hundred and sixty three healthy urban women in Pathumthani, Thailand were recruited. Cervical cancer screening was performed and residual specimen from Pap smears was subjected to PCR to identify the presence of HPV types 16, 18, 31 and 33. Individuals' demographic, health-specific and sexual behavior data were also collected.
Colposcopic biopsy revealed cases with high-grade squamous intraepithelial lesions (HSIL) and low-grade squamous intraepithelial lesions (LSIL). HPV 16 and 18 positive results were associated with abnormal Pap smears. Genotyping gave a 6.1%, 11.8%, 12.1%, and 14.1%, prevalence for HPV types 16, 18, 31 and 33, while 25% were infected with multiple HPV types.
High-risk HPV screening, used with abnormal pathology of HSIL gives 100% sensitivity and negative predictive value. Data from patient showed not significant correlation with neither different religion level of education, marital status, age of first sexual experience nor the number of sexual partners. Thus high-risk HPV screening is a recommended procedure with excellent sensitivity for detecting HSIL.

ABSTRACT: The colposcopic vision guided loop electrosurgical excisional procedure (LEEP) was studied for the effective diagnosis of cervical cancer and cervical intraepithelial neoplasia (CIN).
A total of 199 patients participated in this study. Individual cases were from gynecologic outpatients at Thammasat University Hospital, Thailand. These had diagnoses for CIN and were selected for treatment with colposcopic guided LEEP. The average age of patients in this study was 45. Menopausal women represented 31%, (61/199) of the patients. The most frequently found Pap smear result among these women (44%, 88/199), was that of high-grade squamous intraepithelial lesion. The next most frequent Pap smear result (32%, 64/199) was low-grade squamous intraepithelial lesion. Patients' medical records and outcomes were evaluated for consistency of pathological examination between colposcopic directed biopsy and LEEP. Discrepancies between initial diagnosis and the final diagnosis were also analyzed.
The colposcopic guided LEEP accurately determined 100% of the cervical cancer cases and 84.8 % of the high-grade squamous intraepithelial lesion cases. Involvement of the ectocervical or endocervical margin regions was found to be 5% and 10% respectively, in this study. Excessive bleeding complication, either during the excision and/or postoperative recovery was found in 3% and 6% of cases, respectively.
LEEP under colposcopic vision is a recommended technique for ambulatory management of precancerous lesion and early diagnosis of cervical cancer. This technique significantly reduces rate of positive ectocervical cone margin involvement.

ABSTRACT: To present the indications associated with the increase in cesarean section rate at Thammasat University Hospital during the past three years.
This was a cross-sectional study. Pregnant women who underwent cesarean section between January 2003 and December 2005 at Thammasat University Hospital were recruited for the present study. Cases of fetal anomaly or intrauterine fetal death were excluded. Demographic and obstetric data including indications of cesarean section and pregnancy outcomes were collected and analyzed
Among the 1328, 1402, and 1522 cases of cesarean section (27.31, 27.94, and 29.26%) in 2003, 2004 and 2005 respectively, the major indication was previous cesarean section (29%). Cephalopelvic disproportion (CPD), and elective cesarean section were second, and third most common indication (24.64%, 11.23%) respectively.
The increasing cesarean section rate was due to rising of elective cesarean section or patient's request. Cesarean section without obstetric indication should be reconsidered to lower the cesarean section rate.

ABSTRACT: To investigate the prevalence of abnormal Papanicolaou smear in pregnant patients who attend the Antenatal Care Clinic at Thammasat University Hospital.
Pregnant patients who attended the antenatal care clinic at Thammasat University Hospital from August 2003 to December 2003 were recruited for Papanicolaou test. Patients who had abnormal results of equally or over "abnormal squamous/glandular cells of undetermined significance" were assigned for colposcopy and colposcopic biopsy to confirm the result.
From 500 Papanicolaou smear performed, there were only four patients who had abnormal Pap tests, which were: 2 ASC-US and 2 LSIL. The prevalence of abnormal Pap smear in pregnant patients who attended the antenatal clinic at Thammasat University Hospital was 0.8 percent.
The prevalence of abnormal Papanicolaou smear in pregnant patients attending antenatal care clinic at Thammasat University Hospital was quite low in compares with other literature.

ABSTRACT: To determine the frequency of cervical cytologic abnormalities in patients who were diagnosed as having CIN 1 and had undergone either cryotherapy or expectant management.
A retrospective medical record review of 87 patients with colposcopic cervical biopsy-proven CIN 1, was undertaken including age, parity, menstruation status, cervical cytology reports, colposcopic findings, and cervical cytologic follow-up reports. There were 38 patients (43.7%) treated with cryotherapy and the remainder underwent expectant management.
Mean (SD) age of patients treated with cryotherapy was less than that of the patients who had expectant management (36.2 (9.4) vs 41.1 (9.4) years, respectively, p= 0.02). There were no differences in the frequencies of cervical cytologic abnormalities between the groups at 6- and 12-month-follow-up visits (cryotherapy group vs expectant group: 18.4% vs 18.4% at 6-months and 19.2% vs 16.1% at 12 months).
Cryotherapy and expectant management with cytologic surveillance had comparable frequencies of cytologic abnormalities during a 12-month follow-up period. Expectant management requires adherence to follow up and high quality cytology and colposcopy testing. Therefore, it should be reserved for these settings. Cryotherapy may be more reasonable in women who are likely to be lost to follow up and high quality cytology cannot be guaranteed.
