BACKGROUND: Pregnancy has been associated with differences in thyroid function.1 Maternal thyroid dysfunction has been shown to be associated with fetal and obstetric complications and prompt management is of importance. It has thus been recommended by the British and American Thyroid Association11,12 that trimester-specific thyroid function test reference ranges be used in the assessment of thyroid dysfunction. Normative values across the trimesters of pregnancy have been conducted in several countries13,17,19 and in the Philippines. Reference ranges
in the first and second trimesters of pregnancy were conducted by Patal and Hamin et al. which showed values of TSH 0.14-3.84 uIU/mL, FT4 10.44-21.58 pmol/L, FT3 2.4-5.82 pmol/L in the first trimester and TSH 0.10-4.30 uIU/mL, FT4 9.10-19.40 pmol/L, FT3 2.70- 5.190 pmol/L in the second trimester, respectively.
OBJECTIVE: To establish third trimester reference intervals for free thyroid hormones (free triiodothyronine [FT3], free thyroxine [FT4]) and thyrotropin [TSH] from thyroid peroxidase antibody [TPOAb]-negative Filipino
pregnant women.
DESIGN: This is a prospective, cross-sectional study which included consecutive 200 healthy third-trimester pregnant Filipino women attending Philippine General Hospital (PGH) out-patient services. Serum TSH, FT4, FT3, and TPOAb were measured.
MAIN OUTCOME MEASURES: Reference intervals are based on 2.5th and 97.5th percentiles for TSH, FT4, and FT3 among TPOAb-negative third-trimester pregnant Filipino patients.
ANALYSIS: All numerical data were entered in MS Excel and analyzed using STATA 12. FT3, FT4 and TSH were expressed as mean ±SD, range at 2.5th to 97.5th percentiles.
RESULTS: The reference ranges for TSH, FT4 and FT3 in TPOAb-negative third-trimester pregnant population are as follows: TSH= 0.2-3.0 uIU/mL; FT4 = 9.16-18.64 pmol/L and FT3= 2.09-3.7 pmol/L.
CONCLUSION: Reference ranges for thyroid function tests for the third trimester of TPOAb-negative pregnant Filipino women were determined in this study and are as follows: TSH= 0.2-3.0uIU/mL; FT4 = 9.16-18.64pmol/L and FT3= 2.09-3.7pmol/L.

Majority of cervical cancer are squamous cell carcinoma and adenocarcinoma. The co-existence of two histologic types is rare. This article presents three cases of collision tumors of the cervix within a 10-year review. All underwent radical hysterectomy for an early stage disease. Likewise, it aims to review clinicopathologic features, management, response to treatment and prognosis of these types of tumor in the light of recent literature.

Our objectives were to determine the most significant prognostic factors affecting node metastasis in endometrial cancer and to devise and validate a scoring system for endometrial cancer. The study design consisted of retrospective chart review (operative record and histopathology report) of all endometrial cancer patients who underwent total hysterectomy/radical hysterectomy, bilateral salpingooophorectomy, bilateral pelvic lymph node dissection and peritoneal fluid cytology from September 21, 1989 to February 19, 1999. The analysis included 262 women, 21.4% of whom had pelvic lymph node metastasis.The mean ages for those with metastasis and without metastasis were similar positive lymph node (LN) =53.18 years old; negative LN=51.89 years old; range: positive LN=31-84 years old, negative LN=23-76 years old. Most patients were of low gravidity, with mean=G3, median=G4, mode = GO. The most significant factors affecting pelvic lymph node metastasis were peritoneal fluid cytology, myometrial invasion, cervix involvement and histologic grade as determined by logistic regression and Odds ratio. A prognostic scoring system was devised. All subjects were scored according to a proposed scoring system to determine the latter's clinical utility. A cut-off score of 5 was shown to be significant for pelvic lymph node metastasis. The proposed scoring system may be used to determine the likelihood of pelvic lymph node metastasis for patients who did not have lymphadenectomy and may have an important role in determining the need for adjuvant treatment.

Cervical cancer remains to be one of the leading malignancies among Filipino women. High-risk human papillomavirus (HPV) types, such as 16 and 18, are consistently identified in Filipino women with cervical cancer. Factors identified to increase the likelihood of HPV infection and subsequent development of cervical cancer include young age at first intercourse, low socioeconomic status, high parity, smoking, use of oral contraception and risky sexual behaviors. Cancer screening programs presently available in the Philippines include Pap smears, single visit approach utilizing visual inspection with acetic acid followed by cryotherapy, as well as colposcopy. However, the uptake of screening remains low and is further compounded by the lack of basic knowledge women have regarding screening as an opportunity for prevention of cervical cancer. Prophylactic HPV vaccination of both quadrivalent and bivalent vaccines has already been approved in the Philippines and is gaining popularity among the Filipinos. However, there has been no national or government vaccination policy implemented as of yet. The standard of treatment of cervical cancer is radiotherapy concurrent with chemotherapy. Current researches are directed towards improving availability of both preventive and curative measures of cervical cancer management.

Background: Robotic surgery is a form of minimally invasive surgery wherein the surgeon controls the camera and instruments in a console, remote from the operating room table. Currently, the system in place is the da Vinci Surgical System which was approved by the United States Food and Drug Administration in 2000 for laparoscopic surgery. Since its approval in 2005 for Gynecologic procedures, the da Vinci Surgical System has been used for hysterectomies, lymph node dissections, sacrocolpopexies, myomectomies, and cerclage. Objective: This paper presents the initial seven cases of benign gynecologic diseases operated on utilizing the da Vinci Surgical System in our institution – six hysterectomies and one myomectomy. Methodology: Seven gynecologic surgeries that utilized the da Vinci Surgical System in 2019 until the first quarter of the year 2020 were done. Medical records of the seven patients were reviewed. Results: The average docking time was 38 minutes (range: 25 – 65 minutes) and the average console time was 227 minutes (range: 175 – 345 minutes). The average blood loss was 576 cc (range: 80 – 1200 cc). No cases converted to an abdominal laparotomy and no morbidities were reported. While two cases underwent blood transfusion intraoperatively, all cases were stable post-operatively and were for discharge after two days. On follow-up, all patients were stable with an unremarkable clinical course. Conclusion Our initial experience demonstrates that robotic surgery appears as a viable alternative to traditional approaches. As more cases are to be done in the future, fine-tuning of the logistical set-up and surgical skills are expected, as well as venturing into other gynecologic diseases such as malignancies. Further research must be conducted on various aspects of robotic surgery, such as but not limited to outcome comparison with traditional and other laparoscopic approaches, long term outcomes, patient safety, and patient experience and preference, among others.

Objective: This study aimed to determine the accuracy, sensitivity and specificity of frozen section (FS) in the diagnosis of uterine neoplasm in a tertiary government training hospital. Methodology: This is a retrospective validation study from 2004-2015 involving cases of uterine lesions from gynecologic surgeries. All histopathologic results of frozen and paraffin sections were retrieved and reviewed. Chi square test with 2x2 Fischer Exact test adjustment was used to check for associations. Accuracy indices of FS tool were estimated such as sensitivity, specificity, likelihood ratios, negative and positive predictive values, and overall accuracy. A p-value of < 0.05 alpha is considered significant. Results: A total of 143 uterine specimens were submitted for frozen section analysis. The utilization rate of FS is 1% per year. The FS results were correlated with the final histopathologic diagnosis with 96% agreement rate. Utilizing a median number of 3 sections per specimen provides an overall accuracy rate of 97%. The accuracy rate of FS is equal between combined benign-premalignant and malignant cases at 96%. The accuracy rate is not statistically affected by the procedure by which the specimen was taken, as well as the source and gross morphology of the specimen. Moreover, a minimum of 11 sections per specimen is needed to obtain an accuracy rate of 99-100%. The accuracy rate particularly for endometrial lesions is between 94 and 100%. Conclusion Accuracy rates of frozen section on uterine lesions are high regardless of the sampling procedure and source of the specimen. Increasing the number of sections during FS parallels that of the final histopathologic diagnosis. FS for uterine lesions is a vital and cost-effective intraoperative decision tool to maximize care of patients.

Vulvar intraepithelial neoplasia (VIN) is a precancerous lesion involving the squamous epithelium of the vulva. This retrospective descriptive study aims to determine the prevalence of VIN in a tertiary government hospital in a developing country. Medical records of outpatient consultations with the diagnosis of VIN from January 2000 to June 2012 were reviewed. The prevalence of VIN was 1.6/100,000 women over the 12 years. The diagnosis was based on biopsy results of an incidental finding of vulvar lesions on physical examination. The profile of a patient with VIN was a woman aged 40 years old and above, married, multigravid, nonsmoker, high school graduate, and unemployed. Vulvar lesions noted were multiple hyperpigmented papules located at the posterior labia majora. VIN was associated with abnormal colposcopy findings, and 40% were associated with concomitant cervical disease. Treatment was wide local excision. Prompt diagnosis and appropriate treatment of VIN aim to prevent its progression to vulvar carcinoma. Although vulvar carcinoma is a rare condition, there has been a notable rise in prevalence in recent years. Hence, gynecologists should be vigilant and have a high index of suspicion to detect the disease early in its course.

Background: The interpretation of thyroid hormone function during pregnancy is difficult due to its physiologic changes. Differences in iodine status in previous studies led to different intervals; therefore the use of trimester-specific, method-specific and probably country-specific reference values is advocated. Objective: To establish trimester-specific reference interval for thyroid function tests in pregnant Filipino women. Methodology: Six hundred sixteen pregnant patients (5–40 weeks gestation) attending a tertiary center were recruited. Level of serum thyroid stimulating hormone (TSH) was measured using immunoradiometric assay while free thyroxine (FT4), free triiodothyronine (FT3) and thyroid peroxidase antibodies (TPOAb) were measured by radioimmunoassay method. Main outcome measures are trimester-specific reference interval based on 2.5th and 97.5th percentiles for TSH, FT4 and FT3 among TPOAb-negative pregnant patients. Results: The reference intervals for each trimester were as follows: TSH (0.05-4.24, 0.13-3.95, and 0.20-3.00 uIU/mL); FT4 (9.80-21.88, 9.10-18.95 and 9.16-18.64 pmol/L) and FT3 (2.40-6.20, 2.77-5.00 and 2.09-3.70 pmol/L). FT4 and FT3 are strongly and negatively correlated with age of gestation (p=<0.01and <0.01 respectively). No correlation is found with TSH and age of gestation (p=0.52). Conclusions Trimester-specific intervals among pregnant Filipino women are different from their non-pregnant counterparts and laboratory cutoffs. Thus, these reference values should be used in the country.
