Objectives: There are no standard infection control regulations in transvaginal ultrasound probe disinfection followed in the most prominent local public tertiary referral hospital. Likewise, no studies have evaluated the efficacy of the current method that uses an inexpensive multipurpose antiseptic spray solution. This study aims to evaluate the efficacy of the current practice of manual disinfection of TVS probes and compare it with the performance of an acceptable manual reprocessing method. Methods: A prospective, randomized, controlled study was carried out using a crossover, quasi-experimental design, collecting 119 total samples from the ultrasound transducers before (35 samples) and after disinfection with two manual reprocessing methods, either a locally manufactured multipurpose antiseptic spray (A-Septic® Multipurpose Antiseptic Spray) that is currently used for disinfection or Mikrozid Sensitive®, a ready to use impregnated wipes (42 samples each arm). Disinfection efficacy was evaluated based on microbial culture results. Results: Before disinfection, bacterial growth was observed in 77.1% (27/35) of the probes. After disinfection, 80.95% (34/42) remained contaminated with the antiseptic spray and 21.43% (9/42) with the wipes. The cultures revealed many environmental and pathogenic bacterial isolates, including Burkholderia, Staphylococcus, Acinetobacter, Diphtheroids, and Pseudomonas. Conclusions The currently used method for disinfecting transvaginal transducers in the division is not adequate for decontamination and decreasing the risk of cross contamination among patients. The results call for aggressive disinfection measures and highlight the need to update local standards and formulate and institutionalize these recommendations.

Objectives: Pseudomyxoma peritonei (PMP) in women arises from an appendiceal or ovarian pathology and presents either of two histological subtypes of differing prognosis, disseminated peritoneal adenomucinosis (DPAM), or peritoneal mucinous carcinomatosis (PMCA). This study aimed to evaluate the demographic, clinical, and sonographic features among affected women and the differences between the two histological subtypes. Methods: A retrospective study was conducted involving 36 women with histopathological diagnosis of PMP who had preoperative ultrasound and underwent surgery at the department of obstetrics and gynecology in a tertiary hospital. Demographic and clinical data, ultrasound images and reports, and final histopathology were reviewed. To compare the subtypes, one‑way analysis of variance for continuous data and Chi‑square/Fisher exact test for categorical data were used, with P < 0.05 indicating statistical significance. Results: Patients were mostly >50 years of age, multigravid, and presented with abdominal distention. Ultrasound examinations consistently showed amorphous, mixed echo or echogenic ascites, peritoneal thickening, and omental caking. Adnexal/ovarian masses were detected in 66.7% of cases. Omental caking was significantly more prevalent in PMCA (83.3%; P = 0.0002), whereas larger ovarian tumors (>20 cm) and papillarities were more common in DPAM (both 92.9%; P = 0.0005). Most patients underwent gynecologic surgery (n = 31; 86.1%), and 14 (38.9%) required readmission due to recurrence. The final histopathology revealed largest tumor involvement of the appendix (n = 13; 36.1%), the ovaries (n = 11; 30.5%), or undetermined (n = 12; 33.3%). Conclusions Preoperative diagnosis of PMP is possible based on its clinical and ultrasound features. Although the subtypes are similar in most of these features, certain ultrasound findings may aid in distinguishing them.

Objectives: The use of a scoring system that integrates various factors helps in decision-making and triage for Medically Necessary, Time Sensitive (MeNTS) surgical procedures during the COVID-19 pandemic. This study aimed to determine the clinical characteristics and outcomes of cases who were screened and underwent elective gynecologic surgery at a tertiary hospital using the MeNTS tool for prioritization. Methods: A cross sectional study was carried out using data collected through medical chart review of all gynecologic cases screened in a 6-month period, from June 18, 2020 to December 18, 2020. Results: A total of 155 gynecologic cases were screened, with 134 (86.4%) MeNTS cases and 21 (13.5%) non-MeNTS cases. The median length of stay (5 days), the median operating room time (3 hours and 30 minutes), and median estimated blood loss (400ml) were within the acceptable expected outcome as with the scoring system, albeit with some cases (53%) requiring blood transfusion attributed to low baseline hemoglobin levels. There were no cases with post-operative COVID-19 transmission, needing ICU care and intubation, nor mortalities reported. Conclusions The MeNTS scoring system allowed efficient handling of the backlog of elective gynecologic cases with minimal morbidity and absence of mortality. The study supports the utility of this scoring system in addressing the need of the healthcare system not just to optimally utilize and fairly allocate hospital resources but also to ensure the safety of the patient with the best health service delivery during the pandemic.

Background: Gestational trophoblastic neoplasia (GTN) presents as vascular mass of varying morphology on ultrasound and confirmed through quantitative serum β subunit human chorionic gonadotrophin (β‑hCG). In regions with limited access to β‑hCG, ultrasound plays a crucial role in the initial diagnosis for timely management. Objectives: This study aimed to investigate the associations between ultrasound vascular morphologic features, serum β‑hCG levels, and histopathology in GTN cases. Methodology: A cross‑sectional review was conducted on 113 cases with ultrasound impression of GTN over an 8‑year period. The patient data were extracted from case records, and ultrasound images were categorized based on the distinct features. Associations with β‑hCG levels and histopathology were analyzed using the Chi‑square test and Mann–Whitney U‑test. Statistical significance was set at P < 0.05. Results: A significant association was observed between ultrasound category and serum β‑hCG (P < 0.0001). The compact and diffuse types were more prevalent with β‑hCG levels between 104 to <105 mIU/mL, while the lacunar type was common among patients with ≥105 mIU/mL. However, there was no significant association between ultrasound categories and mean β‑hCG levels. Regarding histopathology, the lacunar type was more common in invasive moles, whereas the compact and diffuse types tended to be seen with choriocarcinoma, although these were not statistically significant (P = 0.182). Conclusions Morphologic types of GTN by gray scale and Doppler ultrasound vary across the different levels of serum β‑hCG and may suggest the histopathological diagnosis. This study provides valuable insights into the ultrasonographic characteristics of GTN, which can aid in its diagnosis and management.

Background and Objectives: Phantom and simulation models are valuable training tools for teaching and skill enhancement, yet high costs and limitations of commercial options drive the search for alternatives. This study evaluated the locally sourced phantom models developed for transvaginal and transabdominal gynecologic interventional ultrasound procedures, aiming to cater to the educational needs of OB-GYN ultrasound subspecialists. Methods: Four phantom models simulating biopsy and cyst aspiration/paracentesis through transvaginal and transabdominal approaches, were developed, and assessed by 37 ultrasound subspecialists in obstetrics and gynecology. The respondents, comprising 19 experienced and 18 with limited exposure to guided procedures, utilized an 11-item Likert-scored questionnaire to evaluate the models' acceptability and suitability for training. Responses were analyzed using descriptive statistics. Results: Both experienced and less-experienced groups consistently assigned high scores, particularly highlighting the realistic ultrasound image and positioning of structures. The models proved effective in enhancing confidence and proficiency during simulation-based training for probe manipulation, aspiration, and biopsy procedures. While respondents identified concerns like durability and needle track marks, no significant differences emerged between the two groups in evaluating the model. Conclusions The overall evaluation of the developed phantom model was positive, showcasing its acceptability among end-users and suitability for training ultrasound-guided procedures in obstetrics and gynecology. The identified issues provide valuable insights for potential improvements in future iterations of the model.

Objectives. The effect of COVID-19 infection in pregnant women and her neonate is not well-understood, with no clear evidence for vertical transmission. This study aims to determine the maternal and neonatal clinical characteristics and the dyad’s outcomes among those infected with COVID-19 infection. Methods. An ambispective cross-sectional study involving pregnant women with confirmed COVID-19 infection was conducted at the Philippine General Hospital from April to August 2020. Two hundred nine obstetric patients were included, 14 of whom consented to specimen collection to determine vertical transmission. Results. The majority of pregnant women with COVID-19 infection and their neonates had good outcomes. Labor, delivery, and the immediate postpartum course were generally uneventful. The all-cause maternal morbidity rate was high at 75.6 per 100 cases during the five-month study period. COVID-19 related morbidities included the development of Guillain-Barré Syndrome. The in-hospital all-cause maternal mortality rate was 1.91 per 100 cases. The causes of maternal death were acute respiratory failure, septic shock, and congenital heart disease (atrial septal defect with Eisenmengerization). The in-hospital, all-cause neonatal mortality rate was 1.04 per 100 neonates of cases. The lone mother and infant deaths were in a postmortem rt-PCR swab negative mother with an rt-PCR swab positive live neonate who eventually succumbed after nine days of life. All 14 dyads with collected specimens that included amniotic fluid, placental tissue, umbilical cord, and neonate nasopharyngeal swab tested negative for SARS-CoV-2 rt-PCR. Conclusion. The prognosis for COVID-19 infected pregnant patients was generally good, with most of the patients discharged improved. Almost all of the neonates born to COVID-19-infected mothers were stable-term infants. There was no evidence for vertical transmission, as shown by negative rt-PCR results for all the additional specimens obtained. In general, the prognosis for COVID-19 infected dyads was good. The majority of the mothers were discharged well with their term infants. All possible maternal sources of COVID-19 infection to the neonate tested negative. This study provided no evidence for vertical transmission.

Background: Major changes in the practice of medicine have been adopted due to the COVID-19 pandemic and have not spared the practice of ultrasound among obstetrician–gynecologists, considered to have higher risk due to unique attributes of an ultrasound examination. Objectives: This study evaluated the awareness, attitudes, perceptions, and practices of the obstetric–gynecologic sonologists in the country during the pandemic, including the use of telesonography. Methodology: A descriptive, cross-sectional survey was conducted through a self-administered, structured questionnaire using an online survey software. Results: There were 120 respondents with postresidency training in ultrasound (54.2%) or in maternal and fetal medicine (43.3%), practicing in different regions, and mostly with teaching affiliations (56.7%). Most are aware of the guidelines on the practice of ultrasound this pandemic and they perceived themselves to be especially vulnerable to the infection. They admitted having feelings of stress, sadness, and depression, and their concerns centered on being infected and potentially transmitting it to their family. These perceptions translated to specific practices that include use of level 3 personal protective equipment, patient screening, triaging, and use of physical barriers to minimize environmental and contamination. While most are consistent with guidelines, some practices are neither based on sound scientific evidence nor correctly adhered to, including noncompliance with appropriate ultrasound transducer cleaning and disinfection. Regarding telesonography, only half of the respondents had good knowledge, with most having informal sources of information on the technology. Although the respondents have a good attitude toward it, only a few (15.8%) admitted to using it, mainly to confer with an expert or colleague (38.3%), and for teaching purposes (11.7%). Conclusions Obstetric–gynecologic sonologists in the Philippines are aware of the risks and have the same attitudes and perspective on COVID-19 infection as other health-care providers. Specific practices have been modified; however, the use of telesonography is not among the changes adopted.
