A case of a 74-year-old male with unilateral nasal obstruction, recurrent epistaxis and a right intranasal mass is presented. It was initially diagnosed as hemangioma but final histopathology report revealed oncocytic carcinoma. Oncocytic carcinoma is a rare tumor of the salivary glands with very few reported cases, most of which involve the parotid gland. It has a tendency to recur with inadequate excision. Diagnosis is histopathologic. It is to be emphasized that adequate tissue samples should be taken in order to provide a definite diagnosis from biopsy, and subsequently institute proper definitive management.

Primary sinonasal ameloblastoma is an extremely rare odontogenic epithelial tumor histomorphologically identical to its gnathic counterparts but with distinct epidemiologic and clinicopathologic characteristics. We present a case of a 46-year-old female with a one year history of recurrent epistaxis, nasal obstruction and frontonasal headache. Clinical examination, CT scan and subsequent surgical excsion revealed an intranasal mass attached to the lateral nasal cavity with histomorphologic features of ameloblastoma and was signed out as extragnathic soft tissue ameloblastoma of the sinonasal area. Extraosseous extragnathic primary sinonasal ameloblastoma are rare but do occur and should be distinguished from infrasellar craniopharyngiomas.

Background:
Despite the rigorous and extremely competitive selection process of medical students at the University of the Philippines College of Medicine (UPCM), a few still performed poorly in academics that resulted in delayed graduation or failure to graduate at all.
Methodology:
Factors potentially associated with delayed graduation and failure to graduate among UPCM medical students were analyzed using univariate and multivariable logistic regression with their demographic and pre-admission academic profiles, namely, Pre-medical General Weighted Average Grade (PGWAG), National Medical Admission Test Scores (NMATs), interview scores, pre-med courses, the school graduated from, and admissions categories as predictors.
Objective:
The objective of this study was to identify the factors that predict the likelihood of not graduating and delayed graduation among the medical students of 24 classes of the UPCM.
Results:
The odds of delayed graduation and failure to graduate were increased by lower PMGWAG, NMAT score, interview score, admission through the special categories, being a non-UP graduate, and with BS Psychology as pre-med course.
Conclusion
The predictors of poor academic performance based on delayed graduation and failure to graduate were the PMGWAG, NMAT, interview scores, admissions category, pre-med course, and the school graduated from. It is recommended that the minimum admissions requirements for PMGWAG be increased particularly among the candidates in the special categories. The selection process in the special categories must put some bearing on the PMGWAGs and NMATs of their applicants.

Objectives: To evaluate abnormal Papanicolau smear results at the Philippine General Hospital (PGH) for the past four years by comparing abnormal smear cytology with histologic interpretations. Possible causes of discrepant results were also determined.
Methods: All Pap smears released as abnormal from January 2014 to December 2017 and the corresponding available biopsies were retrieved. Discrepancy between cytologic and histology diagnosis was assessed and pairs with major discordance were reviewed.
Results: There were a total of 30,237 conventional pap smears signed out of which 239 (0.79%) were abnormal and only 56 (23%) had a subsequent tissue biopsy. The overall concordance rate is 75% while strict or absolute concordance rate is 32%. The overall discordance rate is 25%. Positive predictive value is highest for pap smears signed out as atypical glandular cells favor neoplastic (AGC-NEO) (100%), followed by malignant (93%), high grade squamous intraepithelial lesion (HSIL) (83%), and then atypical squamous cells cannot exclude an HSIL (ASC-H) and atypical squamous cell of undetermined significance (ASCUS), both at 67%.
Conclusions: Considering that the Philippine General Hospital is a referral and academic center, we have a low percentage of abnormal pap smears compared to other developing countries and even a lower percentage of patients who had subsequent biopsies. Cytohistologic correlation detected interpretative as well as sampling errors, and the aim is to work on these deficiencies by improving quality assurance protocols and modifying current local practices of both pathologists and clinicians.

Background and Introduction. The RxBox is a telemedicine device that measures and transmits vital signs to remote experts. It has been deployed to primary care health centers (PCHC) in the Philippines serving disadvantaged populations, to decrease morbidity and mortality due to common diseases and poor access to care. Factors affecting its adoption by healthcare workers is unknown.
Materials and Methods. The study determined social and behavioral factors that affect adoption of a telemedicine device into the clinical workflow using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. This is a mixed methods research using review of records, survey and focused group discussions.
Results and Discussion. RxBox telemedicine devices were installed in 79 primary care health centers (PCHC) and were used a total of 15,705 times within the study period. An ordinary least squares regression analysis using the combined site and individual-level data showed that among the UTAUT parameters, only compatibility, facilitating conditions, and social factors have significant relationships with intent-to-use of the RxBox. The innovation assisted primary care health workers in their clinical responsibilities, improved the stature of their PCHC in the community, and helped in the care for patients. Training and technology support after deployment as well as encouragement by peer and champions (the PCHC physician, local government leaders) reinforced continuous use after training. Users described the experienced improvements in quality of services provided by the PCHC and the consequent benefits to their patients.
Conclusions. These factors should be accounted for in designing strategies to reinforce health workers' attitudes and enhance support towards acceptance and use of novel telemedicine devices into clinical routine in local health centers. Lessons are immediately useful for local leaders in low- and lower middle-income countries that suffer disproportionately from unnecessary maternal deaths and mortality due to non-communicable diseases. This contributes to the body of knowledge and should bolster national-level advocacy to institute an enabling policy on telehealth Information Communication Technology (ICT) and use of Filipino innovations towards health systems strengthening. Results can be used by implementers, evaluators, and regulators of health ICT, especially in resource-poor settings. Likewise, the study can encourage more research in the field to spur more dynamic local health ICT and biomedical device industries.

Background and Objective:
Convalescent plasma therapy (CPT) may reduce the risk of disease progression among patients with COVID-19. This study was undertaken to evaluate the efficacy and safety of CPT in preventing ICU admission among hospitalized COVID-19 patients.
Methods:
In this open-label randomized controlled trial, we randomly assigned hospitalized adult patients with
COVID-19 in a 1:1 ratio to receive convalescent plasma as an adjunct to standard of care or standard of care alone. The primary endpoint was ICU admission within first 28 days of enrolment. Primary safety endpoints include rapid deterioration of respiratory or clinical status within four hours of convalescent plasma transfusion and cumulative incidence of serious adverse events during the study period including transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), severe allergic reactions, and transfusion-related infections.
Results:
A total of 22 patients were assigned to receive convalescent plasma as an adjunct to standard of care and 22 to receive standard of care alone. The median time from onset of COVID-19 symptoms to study enrolment was eight days (IQR, 4 to 10). Two patients (9.1%) in the CPT group and one patient (4.5%) in the control group were admitted to the ICU. The primary outcome measure, ICU admission, was not different between the two groups (q-value >0.9). No patient who received convalescent plasma had rapid deterioration of respiratory/clinical status within four hours of transfusion and none developed TRALI, TACO, anaphylaxis, severe allergic reactions, or transfusion-related infections. There was also no significant difference in the secondary outcomes of 28-day mortality (two patients in the CPT group and none in the control group, q-value >0.90), dialysis-free days, vasopressor-free days, and ICU-free days.
Conclusions
Among hospitalized COVID-19 patients, no significant differences were observed in the need for
ICU admission between patients given CPT as adjunct to standard of care and those who received standard of
care alone. Interpretation is limited by early termination of the trial which may have been underpowered to
detect a clinically important difference.
