In the Philippines, the rate of sexually transmitted infections (STIs) remains high, and statistics show that the highest prevalence is among individuals between the ages of 15 and 24 years old. Unlike Human Immunodeficiency Virus (HIV), other common STIs, such as gonorrhea, syphilis, HPV and herpes are not well discussed.
A descriptive cross-sectional study was conducted to determine the knowledge, awareness and misconceptions of STIs and their practices among men and women aged 15-24 in Sampaloc, Manila. Convenience sampling was conducted among 15- to 24-year-old residents from Barangay 466, excluding healthcare professionals. Sets of questions were adapted from other knowledge, attitudes and practices (KAP) research studies and underwent cross-cultural validation. Questions were also translated and validated into the Filipino language. Data gathering was conducted using self-administered surveys disseminated through online posting and in-community, as well as face-to-face recruitment.
Among the 104 respondents, HIV remained the most recognized STI (99%), while less than half were aware that chlamydia and hepatitis B are STIs. The most common misconception about STI transmission includes the sharing of food and drinks. In terms of prevention, more than half of the participants believed that oral contraceptive pills can prevent STIs. With regards to attitude, 43.3% of the participants disagreed that watching/reading pornographic materials can contribute to risky sexual practices. Among sexually active participants, 19% do not use condoms, and 65% of them do not get tested annually.
In conclusion, the findings from this study reveal a concerning gap in KAP related to STIs among participants aged 15-24 Filipinos. It is recommended that efforts should be directed towards targeted education campaigns and interventions to empower young individuals with accurate information and foster a responsible approach to sexual health.

A unicornuate uterus with a non-communicating rudimentary horn is a rare Müllerian duct anomaly that is frequently underdiagnosed because of its variable clinical presentation and the limitations of conventional imaging modalities. Although not considered a direct cause of infertility, it may coexist with other reproductive pathologies and contribute to adverse reproductive outcomes. Presented here is a case series of three infertile women aged 30–36 years who were diagnosed with a unicornuate uterus and non-communicating rudimentary horn during fertility evaluation. Patient A presented with primary infertility, cyclic pelvic pain, endometriosis, and bilateral tubal disease; Patient B had a seven-year history of primary infertility and was initially suspected to have unilateral tubal obstruction; and Patient C was referred with a presumed diagnosis of uterine didelphys and was subsequently found to have a unicornuate uterus with a non-communicating rudimentary horn and ipsilateral renal agenesis. In all three cases, preoperative imaging failed to establish the definitive diagnosis, which was confirmed intraoperatively through laparoscopy, chromotubation, and hysteroscopy. Patients A and B underwent laparoscopic excision of the rudimentary horn with ipsilateral salpingectomy, while Patient C underwent only ipsilateral salpingectomy. Hysteroscopic transillumination was utilized in one case to facilitate safe laparoscopic dissection and delineation of the hemiuterine anatomy. All patients had uneventful postoperative recovery and were subsequently counseled regarding fertility options. This case series highlights the diagnostic challenges posed by unicornuate uterus with a non-communicating rudimentary horn, emphasizes the importance of a high index of suspicion during infertility work-up, and demonstrates the value of minimally invasive surgical management and hysteroscopic transillumination in selected cases. Early recognition and individualized treatment may help reduce reproductive complications and improve fertility counseling and management.

3.Extra-Ovarian Brenner Tumor of the Cervix in a 43-Year-Old Woman: A Rare Entity with Uncommon Location, Case Report
Christian Soga-ang ; Louella Tan
Philippine Journal of Pathology 2026;(75th PSP Research Competition Abstracts):1-
Introduction:
Brenner tumors are uncommon epithelial-stromal neoplasms that
usually arise in the ovary and comprise a small proportion of ovarian tumors. Extraovarian Brenner tumors are exceedingly rare, and cervical involvement is exceptional.
Because of their unusual location and histologic resemblance to other cervical epithelial
lesions, accurate diagnosis can be challenging on limited biopsy material.
Case Description:
A 43-year-old woman presented with prolonged menstrual
bleeding and a clinically suspicious cervical mass. An initial cervical punch biopsy
demonstrated benign inflammatory and metaplastic changes. Due to persistent
symptoms, a repeat biopsy was performed. Histopathologic examination revealed
well-defined nests and cords of urothelial-like epithelial cells with focal cystic change
embedded in a dense fibrous stroma. The tumor cells showed elongated nuclei
with dense chromatin, inconspicuous nucleoli, and clear cytoplasm with distinct cell
borders. Occasional mitotic figures were present without significant cytologic atypia.
Immunohistochemical studies demonstrated tumor cell positivity for GATA-3, CK7,
p63, and p16, with estrogen receptor positivity in the surrounding stroma, supporting
the diagnosis of a borderline extra-ovarian Brenner tumor of the cervix.
Discussion:
Cervical Brenner tumors are extremely rare and may closely mimic
squamous cell carcinoma, transitional cell carcinoma, or benign squamous metaplasia,
particularly in small biopsy specimens. Recognition of the characteristic nested
urothelial-like architecture, together with a focused immunohistochemical panel,
is essential for accurate classification and to prevent misdiagnosis and unnecessary
aggressive management.
Conclusion
This case highlights a rare borderline extra-ovarian Brenner tumor
arising in the cervix and emphasizes the importance of correlating histomorphologic
features with immunohistochemistry in establishing the correct diagnosis of unusual
cervical neoplasms.

Philippine Journal of Pathology 2026;(75th PSP Research Competition Abstracts):1-
Introduction:
Ovarian lymphoma is rare and often misdiagnosed, as its clinical
presentation can be similar to other more frequent tumors. It accounts for <1% of all
non-Hodgkin lymphomas, with high-grade B-cell lymphoma being the most frequently
implicated subtype.
Case Description:
A 48-year-old woman presented with bilateral ovarian masses,
elevated CA-125, and extensive abdominal and thoracic lymphadenopathy. She was
managed as advanced ovarian cancer and underwent TAHBSO. Grossly, both ovaries
were enlarged and nodular. Histology showed a round cell neoplasm composed
predominantly of medium-sized, cleaved lymphocytes, admixed with scattered larger
atypical cells. Initial immunohistochemistry panel demonstrated diffuse CD45 positivity
and negativity for AE1/AE3, Inhibin, SALL4, Desmin, and Calretinin. Subsequently,
CD20 and PAX5 showed diffuse reactivity. CD10, BCL2, and BCL6 highlighted
neoplastic follicles. CD3 was negative. High-grade B-cell lymphoma was considered;
however, the Ki-67 proliferative index was 38%, and c-MYC expression was low (5%). A
final diagnosis of follicular lymphoma involving both ovaries was rendered.
Discussion:
The clinical presentation strongly suggested advanced ovarian carcinoma.
However, histologic and immunophenotypic evaluation established lymphoma. Although
aggressive subtypes are more common in advanced cases, indolent entities such as
follicular lymphoma should also be considered, particularly in resource-limited settings
where delays in diagnosis occur. Distinguishing lymphoma from carcinoma is critical, as
management differs significantly and misclassification may lead to overtreatment.
Conclusion
Recognition of ovarian lymphoma is critical, as accurate diagnosis alters
management and prevents unnecessary radical surgery.

Persistent infection with high-risk human papillomavirus(HR-HPV) is the primary etiological factor in cervical lesions and cervical cancer. Toll-like receptors(TLRs), as important pattern recognition receptors of the innate immune system, play a key role in the persistence of cervical HR-HPV infection. The "latent pathogen theory" in traditional Chinese medicine(TCM) holds that latent pathogens have both "latent" and "triggered" characteristics, which closely resemble the persistent infection and latent pathogenic potential of cervical HR-HPV. Guided by the "latent pathogen theory" and using contemporary immunological techniques, this paper explores the bidirectional immunomodulatory effects of TLRs in the persistence of cervical HR-HPV infection and their relationship with latent pathogens. The results indicate that TLRs play a crucial role in immune recognition and modulation. Dysregulation and overactivation of TLRs can induce chronic inflammation, allowing cervical HR-HPV to persist and evade immune detection. TLR dysfunction, coupled with a deficiency in healthy Qi that prevents the expulsion of pathogens, is a critical factor in the pathogenicity of latent pathogens. Restoring healthy Qi to modulate the immune functions of TLRs emerges as an important strategy for clearing cervical HR-HPV infection. By harmonizing the spleen and kidney and regulating immune balance, it is possible to reverse cervical HR-HPV infection, providing a scientific basis for clinical research.

This study primarily investigates the effect of Liuwei Dihuang Pills on the activation and proliferation of female germline stem cells(FGSCs) in the ovaries and cortex of mice with premature ovarian failure(POF), and how it improves ovarian function. ICR mice were randomly divided into the control group, model group, Liuwei Dihuang Pills group, Liuwei Dihuang Pills double-dose group, and estradiol valerate group. A mouse model of POF was established by intraperitoneal injection of cyclophosphamide. After successful modeling, the mice were treated with Liuwei Dihuang Pills or estradiol valerate for 28 days. Vaginal smears were prepared to observe the estrous cycle and body weight. After the last administration, mice were sacrificed and sampled. Serum levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-Müllerian hormone(AMH) were measured by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe ovarian morphology and to count follicles at all stages to evaluate ovarian function. Immunohistochemistry was used to detect the expression of mouse vasa homolog(MVH), a marker of ovarian FGSCs. Immunofluorescence staining, using co-labeling of MVH and proliferating cell nuclear antigen(PCNA), was used to detect the expression and localization of specific markers of FGSCs. Western blot was employed to assess the protein expression of MVH, octamer-binding transcription factor 4(Oct4), and PCNA in the ovaries. The results showed that compared with the control group, the model group exhibited disordered estrous cycles, decreased ovarian index, increased atretic follicles, and a reduced number of follicles at all stages. FSH and LH levels were significantly elevated, while AMH and E_2 levels were significantly reduced, indicating the success of the model. After treatment with Liuwei Dihuang Pills or estradiol valerate, hormone levels improved, the number of atretic follicles decreased, and the number of follicles at all stages increased. MVH marker protein and PCNA proliferative protein expression in ovarian tissue also increased. These results suggest that Liuwei Dihuang Pills regulate estrous cycles and hormone disorders in POF mice, promote the proliferation of FGSCs, improve follicular development in POF mice, and enhance ovarian function.

7.The influence of knowledge, attitude, and motivational factors on the willingness of mothers for their female children to undergo human papillomavirus vaccination
Philippine Journal of Obstetrics and Gynecology 2025;49(1):18-42
BACKGROUND
Cervical cancer remains to be the second leading cancer and cause of cancer-related deaths among Filipino women despite the use of the Papanicolaou screening. Latest research has shown that the human papillomavirus (HPV) is a necessary cause of cervical cancer. With major morbidity and high mortality rates associated with HPV infection and cervical cancer, several modes of primary and secondary forms of prevention have to be implemented. Among the primary modes of prevention is the administration of the preventive vaccine, which has consistently shown to decrease substantially HPV disease and cervical cancer rates in developed countries. In our country, before a successful vaccination, program is implemented, several sociocultural issues have to be addressed. Knowledge, attitude, and motivational factors are vital in determining acceptance of the vaccine. One relevant setting is exploring the willingness of mothers to get their female children vaccinated even before they become sexually active.
OBJECTIVESThe aim of the study was to determine the association of the knowledge, attitude, and motivational factors of mothers on their willingness for their female children aged 9–13 years to undergo HPV vaccination at a tertiary government hospital.
STUDY DESIGNThis was a cross-sectional study that was carried out at a government institution.
POPULATIONThe population consisted of 352 mothers with female children aged 9–13 years consulting the outpatient clinics at the department of obstetrics and gynecology at a tertiary government hospital.
MATERIALS AND METHODSA pretested and validated survey was given to 352 respondents. They were asked to answer a self-administered questionnaire that included sociodemographic, reproductive, sexual history variables, knowledge, and attitude, and motivational factors toward the disease and the associated vaccine.
RESULTSUsing the survey proportion estimation methods, the prevalence of women who were willing to enroll their daughters for HPV vaccination was 97.18% (n = 42, 95% confidence interval [CI]: 94.91 to 98.46%). It can be noted that only a third of the sample had high knowledge on the vaccine and its use 34.93% (n = 124, 95% CI: 30.25 to 39.92%). More women who reached college level (χ2: 5.67) and also those whose youngest child was between 11 and 13 years old (χ2: 8.82)-had higher knowledge scores than otherwise. Those who have an annual income of greater than or equal to P 60,000 (χ2: 16.55) and are non-Catholic (χ2: 18.77) – also appeared to have higher knowledge ratings on the questionnaire. Women who never to a few times a year attend church-related activities had higher knowledge scores compared to women who were more frequent goers (χ2: 16.33). For the attitude toward the vaccine, more mothers believed that getting the vaccine would not have an effect on a girl’s sexual activity and most agreed that they would not be viewed as bad parents. Most women also did not believe that religion would affect their willingness to vaccinate their children. There was an association in the degree of agreement between negative and positive attitudes from the Chi-square test performed (χ2: 7.44, P: 0.01). There were more agreeing responses from factors determining positive attitude and more disagreeing responses in the factors determining negative attitude. With regard to motivational factors, more women agreed that the cost was prohibitive and that they were more willing if only two doses would be required for their daughters. They were also not concerned about what other parents may think about getting the vaccine. Most answered that they were willing to follow their doctors’ recommendations and they have trust in vaccine manufacturers. Most women were also concerned that their daughters may get cervical cancer in the future. There was no difference in the proportion of agreeing responses between positive and negative motivating factors among the study participants (Z: 0.30, P: 0.79). This suggested that these factors could be important predictors of willingness to use vaccination on their children. Based on the crude odds ratios from the logistic regression, the likelihood of being willing to administer HPV vaccine to their children was almost twice as the knowledge score and scores on the positive attitude items increased, and was found to be statistically significant. At the same time, the odds of willingness increased by more than twice as the score on the negative attitude items decreased, and was also significant. There was no noted association for the other predictors of the association.
CONCLUSIONThe role of knowledge and attitudes on the negative perceptions on the vaccine were important predictors of the willingness of mothers to have their female children vaccinated against HPV infection.

8.Umbilical endometriosis: A case series on the different approaches in management
Janelle Marie Guinto Doloiras ; Regina Paz A. Tan-Espiritu
Philippine Journal of Obstetrics and Gynecology 2025;49(1):68-73
Endometriosis is defined as the presence and growth of the glands and stroma of the lining of the uterus in an aberrant or heterotopic location. The cause of endometriosis is uncertain and involves many mechanisms including retrograde menstruation, vascular dissemination, metaplasia, immunologic, and hormonal influences to name a few. Primary umbilical endometriosis is a rare disorder defined as the presence of ectopic endometrial tissue within the umbilicus. It commonly presents with catamenial pain and bleeding from an umbilical nodule. It is a rare condition and treatment has not been standardized yet due to the limited number of cases. Surgical management is the treatment of choice to avoid local recurrence while hormone therapy may be used preoperatively for symptomatic relief. This paper reports a series of recently observed cases of primary umbilical endometriosis with main aim of discussing the different approaches in the management of this rare condition.

Philippine Journal of Reproductive Endocrinology and Infertility 2025;22(1):7-15
In Mayer-Rokitansky-K0ster-Hauser (MRKH) syndrome, the development of the uterus and some parts of the vagina is either completely absent or reduced. It is a rare congenital anomaly, and affects one in 4,000-5,000 female births and commonly presents as primary amenorrhea. Approximately 6% - 10% of these patients with MRKH syndrome report persistent pelvic pain, which may be attributed to the presence of myomas, endometriosis, adenomyosis or hematometra caused by a functioning endometrial tissue in a uterine remnant. This paper presents the case of a 37 year old nulligravid who experienced severe cyclic hypogastric pain, and was subsequently diagnosed with MRKH syndrome with adenomyosis. Clinical evaluation and definitive management of the index case are discussed.
