BACKGROUND

Scabies, caused by Sarcoptes scabiei var. hominis, is a prevalent and burdensome skin disease in the Philippines, ranking second in disability. Recognized as a neglected tropical disease (NTD) by the WHO, scabies management is targeted for inclusion in universal healthcare programs worldwide by 2030. Current treatment involves topical neurotoxic drugs like permethrin, but issues such as expense and inconvenience hinder compliance. Oral ivermectin, recommended by the WHO only recently, is more cost-effective and easier to administer but is considered a second-line option in clinical practice guidelines. This research aimed to determine the comparative efficacy, safety, cost-effectiveness, and acceptability of oral ivermectin, alone or in combination with topical permethrin, versus topical permethrin alone, in the treatment of classic scabies among Filipino patients.

This 4-part study was conducted from July 2021 to September 2023 and aimed to compare the efficacy, safety, cost-effectiveness, and acceptability of oral ivermectin alone or in combination with topical permethrin versus topical permethrin alone for treating classic scabies among Filipino patients. Quantitative methods included a systematic review and network meta-analysis of 38 randomized controlled trials (RCTs) and a pharmacoeconomic evaluation using decision tree modeling. Qualitative methods involved a multiple case study of patient experiences and perceptions and in-depth interviews with physicians.

There seems to be comparable efficacy between oral ivermectin and permethrin, with limited evidence favoring the combination ivermectin/permethrin regimen. Adverse events were minor, and cost-effectiveness analyses favored ivermectin-based regimens over permethrin. Patient and physician perspectives supported the effectiveness of all treatments, with oral ivermectin recognized as safe but underutilized.

Evidence synthesis suggests that oral ivermectin, especially in combination with permethrin, could be a viable and cost-effective alternative for scabies treatment in the Philippines. The optimal dosing regimen, safety in specific populations, and factors influencing treatment choice need further exploration. Recommendations include advocating for oral ivermectin inclusion in regulatory guidelines and national formulary, considering it as a first- or second- line treatment, and conducting further research, including mixed-methods designs, to confirm efficacy, safety, and cost-effectiveness in different settings. Shared decision-making, considering ethical, logistical, socioeconomic, and psychological aspects, is crucial in implementing effective scabies control programs.

Objective: This study aims to describe the design, development, and implementation of the UP Med Webinars as a method for delivering continuing medical education online. Methods: Thematic analysis was done to organize information to describe the three phases of development: design, planning, and implementation of the UP Med Webinars for the period of 2015-2021. Results: The University of the Philippines Medical Alumni Society, in collaboration with seven units from the University of the Philippines Manila, contributed resources to the design of the UP Med Webinars. A committee on continuing medical education composed of alumni celebrating their silver jubilee led the planning each year. A total of 435 webinars were conducted from 2015 to 2021. Attendance steadily grew from less than 50 to more than 600 participants per session. These webinars covered a wide range of topics and were attended by medical professionals from different disciplines. Continuing professional development units were provided for free. Conclusion The UP Med Webinars was able to deliver post-graduate content online to healthcare professionals in the Philippine medical community. A well-organized set of partners collaborating to design and develop continuing medical education online was key to its continuous implementation and expansion.

Objective: We investigated the effect of personal protective equipment (PPE) on prevention of COVID-19 on health care workers (HCW) assigned in the wards, intensive care (ICU) and emergency room (ER). Methods: We searched MEDLINE, Cochrane CENTRAL as of 30 April 2021, as well as trial registers, preprint sites and COVID-19 living evidence sites. We included studies that compared use of PPE versus no use in the prevention of COVID-19. We screened studies, extracted data, assessed risk of bias and certainty of evidence using GRADE approach. Results: Five observational studies (three cohort and two case control) were found. There was moderate certainty of evidence that the use of Level 2 PPE (OR 0.03 [95% CI 0, 0.19]; 1 study, n = 5542) was protective for HCW. Level 2 PPE used N95 or higher standard respirators, goggles/protective mask, medical protective clothing and disposable hats, gloves and shoe covers. We also confirmed with moderate certainty evidence the protective use of N95 respirators (OR 0.035 [95% CI 0.002, 0.603]; 1 study, n = 493). There was very low certainty of evidence that demonstrated the protective effect of face shield (OR 0.338 [95% CI 0.272, 0.420]; 2 studies, n = 6717, I2 = 45% P < 0.00001). Very low certainty of evidence showed no significance difference with use of face/surgical mask (OR 1.40 [95% CI 0.30, 6.42]; 1 study, n = 186), gowns (OR 0.768 [95% 0.314, 1.876]; 1 study, n = 179) and disposable gloves (OR 0.62 [95% CI 0.13, 2.90]; 1 study, n = 179) when attending to patients with COVID-19. Conclusion There was lower odds of COVID-19 infection in HCW assigned to the wards, ICU and ER with possible direct contact with COVID-19 patients who wear Level 2 PPE including N95 respirators and face shields.

Background and Objective: Lockdowns due to COVID-19 pandemic led to a shift to online learning in the University of the Philippines-College of Medicine. The study of gross anatomy is difficult in itself but was compounded by the lack of cadaveric dissection. To bridge this learning gap, medical students had a limited face-to-face activity with cadaveric prosection. As a supplement, dissection videos on gastrointestinal anatomy were viewed prior to the activity. This study aimed to determine the perceptions and experiences of students on the use of dissection videos. Methods: We described the perceptions of students on the dissection videos based on their evaluation form responses after rotating in the OS 206 course module on gastrointestinal anatomy. A 5-item evaluation form was rated using a 4-point Likert scale. Categorical variables were described by frequency and percentages using Microsoft Excel. Results: A large majority (97% to 99%) strongly agreed that the videos were easy to access and had good audio-video quality. Around 68%-70% strongly agreed that the videos enhanced their understanding and made their learning experience pleasant and enjoyable. Around 70% would recommend the videos to fellow students. Only a few (<3%) had negative perceptions on the videos. Conclusion Dissection videos on gastrointestinal anatomy prior to cadaveric prosection laboratory sessions were perceived by medical students as accessible, good quality, and helpful aids in the study of gross anatomy.

Introduction: Rotator cuff tears are one of the common etiologies of shoulder pain. Rotator cuff repair is recommended for a patient who failed conservative treatment. Proper knowledge of the rotator cuff footprint is needed in restoring correct anatomy during the repair. The size of the footprint is important in determining the kind of repair. Objective: This study aimed to define the average measurements of the rotator cuff footprint on the humerus in Filipino cadavers. Methods: This is a descriptive, cross-sectional study of preserved human cadaver upper extremity specimens. We measured the length, width, and shape of the supraspinatus, infraspinatus, subscapularis, and teres minor. Results: We obtained 27 upper extremity specimens. The median age of the source cadavers was 50.5 years with the equal male-to-female distribution. The mean measurement of the supraspinatus is 22.92 mm in length and 10.17 mm in width. The shape of the supraspinatus was found to be trapezoidal. The infraspinatus length was found to be 17.20 mm and the width at 10.72 mm. Its shape was found to be trapezoidal. The teres minor length was measured at 15.15 mm and the width at 11.04 mm. The shape was mostly trapezoidal but some were triangular. Finally, the subscapularis length was 17.68 mm while the width was 11.26 mm. The shape was trapezoidal or comma-shaped. Conclusion The average measurement of the rotator cuff footprint was found to be smaller in our study than reported in terms of length and width. The footprint shape was similar to the studies reported.

Background: Pooled data from observational studies suggest that patients with serum vitamin D levels below 30 ng/mL had an increased risk of infection and mortality from COVID-19. This rapid review aimed to determine the efficacy and safety of vitamin D as an adjunct treatment for COVID-19. Methods: We searched MEDLINE (PubMed) and CENTRAL up to July 18, 2021. We also searched trial registries, gray literature, and reference lists of included and excluded studies in the search as well as COVID-19 guidelines. Two reviewers independently screened titles and abstracts, collected data, and assessed for risk of bias. Meta-analysis was conducted, and an evidence profile table using GRADEpro was generated. Outcomes included were mortality, need for mechanical ventilator or progression of oxygen support, duration of mechanical ventilation, ICU admission, hospital length of stay, SARS-CoV-2 positivity at day 21, and adverse events. Results: We found four RCTs (3 low risk of bias and 1 high risk of bias). The sources of bias among the RCTs were unclear allocation, lack of blinding of patients, caregivers, and outcome assessors, and high drop-out rate. This rapid review found that the effects of vitamin D are inconclusive for the following outcomes: mortality (pooled RR 0.62, 95% CI [0.16 to 2.41], I2=49%; n=443, 3 RCTs, very low certainty of evidence), need for mechanical ventilator or progression of oxygen support (RR 0.52, 95% CI [0.24 to 1.13], n=237, 1 RCT, low certainty of evidence), and ICU admission (pooled RR 0.37, 95% CI [0.09 to 1.61], I2=78%; n=443, 3 RCTs, very low certainty of evidence. No significant reduction in hospital length of stay was found among those treated with vitamin D (MD 0 days, 95% CI [-1.19 to 1.09], low certainty of evidence). The duration of mechanical ventilation was also was also not significantly shortened in the treatment group (15 days) compared with placebo (12.8 days), MD 2.2 days, 95% CI [-8.4 to 12.8], low certainty of evidence. Interestingly, a higher proportion of those supplemented with vitamin D showed virologic clearance for COVID-19 on day 21 (RR 3.0, 95% CI [1.26 to 7.14], n=40, 1 RCT). At dosages between 60,000 to 200,000 IU of cholecalciferol, only one episode of vomiting (0.8%) was reported. Conclusion Based on the evidence found, we are uncertain whether vitamin D is beneficial or harmful for patients with COVID-19. There is very low certainty of evidence to recommend the use of vitamin D supplements as an adjunct treatment for patients with COVID-19. Vitamin D supplementation for patients with COVID-19 should be limited to clinical trials or among those with proven vitamin D deficiency. More published studies are awaited to explore the benefit or harm of vitamin D for COVID-19.

Background: Pityriasis versicolor is a common fungal infection of the superficial skin layer caused by Malassezia furfur, a normal commensal in the skin. Keratolytic agents are popular, cheap, and readily available over-the-counter treatments for pityriasis versicolor. Conventional antifungal agents are more expensive, requiring prescription, and may induce resistant strains. However, evidence of their comparative safety and efficacy is still lacking. Objectives: To assess the efficacy and safety of synthetic antifungals compared to keratolytic agents in the topical treatment of pityriasis versicolor through a systematic review. Methods: We searched the following databases: MEDLINE (from 1966) through PubMed, CENTRAL (Issue 9 of 12, September 2021), EMBASE (from 1974), LILACS (from 1987); Herdin (from 1970), www.clinicaltrials.gov, www. isrctn.com, www.trialregister.nl. We contacted researchers in the field, hand searched relevant conference abstracts, and the Journal of the Philippine Dermatological Society 1992-2019. We included all randomized controlled trials involving patients with diagnosed active pityriasis versicolor where topical antifungal was compared with a topical keratolytic for treatment. Two review authors independently applied eligibility criteria, assessed risk of bias using the Cochrane collaboration tool, and extracted data from included studies. We used RevMan 5.3 to pool dichotomous outcomes using risk ratios (RR) and continuous outcomes using the mean difference (MD), using random-effects meta-analysis. We tested for statistical heterogeneity using both the Chi² test and the I² test. We presented results using forest plots with 95% confidence intervals. We planned to create a funnel plot to determine publication bias but were unable to due to few studies. A Summary of Findings table was created using GRADE profile software for the primary outcomes. Results: We included 8 RCTs with a total of 617 participants that compared azole preparations (ketoconazole, bifonazole and econazole) versus keratolytic agents (selenium sulfide, adapalene, salicylic-benzoic acid). Pooled data showed that azoles did not significantly differ from keratolytic agents for clinical cure (RR 0.99, 0.88, 1.12; 4 RCTs, N=274, I2=55%; very low-quality evidence), and adverse events (0.59 [0.17, 2.06]; very low-quality evidence) based on 6 RCTs (N=536). There were two patients given a keratolytic agent (selenium sulfide shampoo) who had acute dermatitis and discontinued treatment. Conclusion It is uncertain whether topical azoles are as effective as keratolytic agents in clinical clearance and occurrence of adverse events in patients with pityriasis versicolor. A wider search of grey literature and local studies are warranted. Larger RCTs with low risk of bias are recommended.

Background: Scabies is the second most common cause of disability among skin diseases in the Philippines as of 2019. There is no large nationwide study describing the epidemiologic profile of scabies in the country. Objective. This study aimed to describe the demographic, seasonal, and geographic profile of scabies in the Philippines. Methods: We compared secondary data of two local patient registries (Philippine Dermatological Society, PDS, 2010 to 2021; and Philippine Pediatric Society, PPS, 2009 to 2021) for reported cases of scabies in the Philippines. We reported the frequency and percentage distribution according to age, sex, month, year, and type of diagnosis, and region. Results: The median annual frequency of scabies cases (mostly outpatient) for PDS (from year 2010) was 4087 (range ([QR], 342-6422 [3271.5]), while it was 183 (range [IQR], 64-234 [96.5]) (all inpatient) for PPS (from year 2009). There was a reduction to one-third (PDS) and one-fourth (PPS) of pre-pandemic numbers during the pandemic years (2020- 2021). The peak months for scabies cases were the cooler months: January (median, 12.1% of annual cases; range [IQR], 2.6%-31.4% [3.6%]) to February (median, 10.0% of annual cases; range [IQR], 1.5%-27.8% [2.5%]) based on PDS data, and November (median, 10.0% of annual cases; range [IQR], 0.0%-24.3% [7.0%]) to January (median, 9.0% of annual cases; range [IQR], 0.0%-24.3% [6.6%]) for PPS data. Overall, for PDS, age 1-4 years is the most affected age group (median, PDS, 17.5% of annual cases; range [IQR], 11.9%-25.4% [8.1%]), while it was the less than 1-yearolds (median annual cases, 48.9%; range [IQR], 29.1%-67.3% [13.20%]) among PPS pediatric population aged 0 to 18 years. Males (median, 53.9% of annual cases; range [IQR], 45.0%-67.2% [8.8%]) were more affected than females in PPS. While for PDS during earlier years (prior to 2015), males (median, 51.6% of annual cases from 2010 to 2014; range [IQR], 47.4%-52.9% [0.2%]) were more affected than females. However, males became less affected than females with median, 44.7% of annual cases from 2015 onwards (range [IQR], 43.4%-46.5% [1.2%]). NCR was the region with the highest frequency of cases in PPS (median, 52.6% of annual cases; range [IQR], 22.7%-75.0% [20.4%]). The 2nd most affected regions were Central/Eastern Visayas (34.2%, 2009-2013; range [IQR], 17.9%-54.1% [5.3%]), Bicol region (12%; 2014 to 2018; range [IQR], 17.9%-54.1% [7.4%]), Central Luzon (18%; 2019), Central/Eastern Visayas (29%, 2020), and Northern/Central Mindanao (17%, 2021). Conclusion Scabies was commonly seen in the younger age group, slightly more in females in the PDS, while slightly more among males in the PPS, in the cooler months of the year, and in the urbanized NCR.

Background: Oral azole drugs are a second-line option for the treatment of pityriasis versicolor but evidence on their efficacy and safety is unclear. Objectives. To determine the efficacy and safety of oral azoles in the treatment of patients with pityriasis Versicolor.

Methods: We searched MEDLINE, CENTRAL, EMBASE, LILACS, and HERDIN, from inception to the period between January to February 2014. We did not restrict the search by language or publication status. We included randomized controlled trials (RCTs) that compared the efficacy of oral azoles with placebo or no treatment, with topical agents, other oral azoles or dosing regimens in the treatment of pityriasis Versicolor, and that measured any of the pre-specified outcomes (mycologic cure, clinical cure, recurrence, duration to cure, time-to-cure, and quality of life). For adverse effects, we also included non-randomized studies (NRS). We used Cochrane methods to select studies, extract data, assess the risk of bias, pool studies, and calculate for treatment effects.

Results: We included 38 RCTs (n=2894) and 56 NRS (n=3452). Overall, there were few pooled studies and evidence was low to moderate quality. Oral azoles were more effective than placebo (mycologic cure, RR 11.34, 95% CI 4.90, 26.28; 3 RCTs, n=131; I2=0%; low quality of evidence) and as effective as topical agents (mycologic cure, RR 1.02, 95% CI 0.86, 1.21; 4 RCTs, n=232; I2=60%; moderate quality of evidence).There were few adverse effects and were mostly minor and transient.

Conclusions: Oral azoles may be more effective than placebo, and are probably as effective as topical agents in the treatment of PV. Triazoles are probably as effective as ketoconazole. Adverse effects were few, mostly minor, and transient.

OBJECTIVE: This study assessed the reliability and validity of a Filipino version of the Cardiff Acne Disability Index.
METHODS: In Phase 1, the Cardiff Acne Disability Index (CADI) was translated into Filipino as the Cardiff Indeks ng Kapansanan ng may Tigyawat (CIKT) following international guidelines on translation and cultural adaptation, and passed a cognitive debriefing test (a form of face validity testing). In Phase 2, the CIKT was administered to 400 public high school students (11-18 years old). Cronbach's ? was used to measure reliability while construct validity was determined by comparing 1) the CIKT scores of adolescents with acne and those without acne and 2) the CIKT scores with the scores of the Taluntunan ng Kalidad ng Buhay na Hinggil sa Dermatolohiya (TKBD), which is a validated Filipino version of the Dermatology Life Quality Index.
RESULTS: Cronbach's ? showed an adequate internal consistency of 0.7. The linear regression coefficient for those with and without acne was 0.98 (CI 0.59, 1.37) (p = 0.00) while the Spearman correlation showed a positive correlation between the CIKT and the TKBD (0.58, p=0.00), both indicating validity.
CONCLUSION: The CIKT is a reliable and valid Filipino translation of the CADI.
