BACKGROUND

With the utility of nail dermoscopy to supplement the diagnosis of onychomycosis, studies have been done in describing common findings. However, most of these were based in Europe and the Americas. Given the geographical variation of onychomycosis, a local study is needed.

The general objective of this cross-sectional study is to determine the different patterns among the clinical subtypes of laboratory diagnosed onychomycosis patients seen at the Philippine General Hospital (PGH).

Clinically suspected Filipino onychomycosis patients seen at the PGH - Department of Dermatology, and at the PGH inpatient wards were recruited. All patients underwent the following: direct KOH microscopy, fungal culture studies, and nail clipping with PAS staining.

A total of 75 samples were included; 93.33% of the samples were categorized as DLSO subtype, 5.33% as TDO, and 1.33% as PSO. The three most common onychoscopic patterns were subungual hyperkeratosis (93.33%), chromonychia (85.33%), and longitudinal striae in 81.33%. KOH was positive in 57.33% of the cases, cultures in 38.67% and PAS stain in 80%. Onychoscopic pattern was not associated with clinical type of onychomycosis and causative organism. Negative KOH result was associated with linear edges (p=0.02).

Among patients with clinical and laboratory diagnosed onychomycosis, linear edges and jagged proximal edges were associated with negative KOH microscopy and fungal CS, respectively. Hence, in situations where such examinations are negative despite a strong clinical suspicion of onychomycosis, the above onychoscopic findings can be used for empirical diagnosis.

Botryomycosis is a rare pyogenic disease that presents with chronic suppurative and granulomatous skin lesions, commonly caused by Staphylococcus aureus. We report a case of botryomycosis presenting similarly to mycetoma, secondary to the emerging cutaneous pathogen Staphylococcus simulans. A 46-year-old female who previously worked in a wet market presented with a 13-year history of suppurative papules on a gradually enlarging right foot, and pain on ambulation. She had no systemic symptoms or co-morbidities, and does not recall preceding trauma. Physical examination showed brawny edema of the right foot with multiple sinus tracts draining purulent discharge. The clinical diagnosis at presentation was mycetoma. Magnetic resonance imaging showed a soft tissue mass involving the right foot and ankle with osseous destruction. Biopsy revealed suppurative granulomatous dermatitis; staining with Grocott methenamine silver did not highlight fungal elements. Potassium hydroxide mount of the purulent discharge did not show grains or hyphal elements. Tissue cultures showed growth of co-trimoxazole-susceptible Staphylococcus simulans. The patient was managed as a case of botryomycosis and treated with co-trimoxazole for 12 months. There was a significant decrease in right foot circumference along with scarring and resolution of associated pain. Repeat biopsy showed no evidence of infection. This is the first reported case of botryomycosis in the Philippines as well as the first report citing Staphyloccocus simulans as a causative agent. Botryomycosis is an important differential in patients clinically presenting as mycetoma. Animal pathogens may need to be considered as etiologic agents in at-risk patients with chronic subcutaneous infections.

BACKGROUND

Seborrheic keratosis is a common benign skin tumor treated with invasive methods like electrodessication, cryotherapy, or surgery. Topical therapy with trichloroacetic acid (TCA) may be a cheaper, non-invasive alternative with less complications. While TCA has been studied for other skin conditions, more research is needed on its use for seborrheic keratosis.

To compare the safety and efficacy of one time application of 80% TCA peel to 65% TCA peel in the clearance of raised seborrheic keratosis in Filipino patients.

One hundred one patients were randomized to either 80% or 65% TCA groups. Each participant underwent one session of treatment and was followed up after a month. Pre- and post-test size and thickness of lesions were compared between groups.

Based on Physician’s Lesion Assessment (PLA), both concentrations of TCA achieved high treatment success (TCA80: 66.7%, TCA65: 68%, p-value 0.89). A similar trend was observed based on Subject’s Self-Assessment (TCA80: 74%, TCA65: 74.5%, p-value 0.95). Similar reductions in lesion size and thickness were observed in both concentrations. In terms of safety, pain, pruritus, and erythema were mostly observed during and immediately after treatment, with little to no adverse events observed after 1 month in both groups.

One time application of either 80% or 65% TCA is effective in decreasing the size and thickness of seborrheic keratosis with little to no complications 1 month post- treatment. Both concentrations were safe, causing minimal and non-persistent pain, pruritus, and erythema immediately after application.

INTRODUCTION: Pyoderma gangrenosum is a rare neutrophilic dermatoses in children of unknown etiology. Its occurrence may be associated with a systemic condition. In most cases, diagnosis is late and treatment is sometimes refractory to conventional therapies especially if the underlying disorder is undetected. CASE REPORT: A 3-year-old Filipino male presented with a one-year history of extensive ulcers over the nape, chest, back and lower extremities which started as a solitary painful pustule over the right gluteal area. Central healing was observed with cribriform scarring. Patient was previously treated as a case of skin infection without success. Significant laboratory findings showed severe anemia, neutrophilia, increased ferritin and increased ESR. Initial hemoglobin electrophoresis showed normal profile with mild microcytic anemia. Bacterial culture and ANA (anti-nuclear antigen) were negative. A course of oral prednisone (1-2mkd) and dapsone (2mkd) were given for a month with no improvement of the lesions. Folic acid alone was started at 5mg per day for anemia. After 2 weeks, lesions significantly improved. Three years later, upon repeat hemoglobin electrophoresis test, patient was diagnosed with alpha-thalassemia trait. Folic acid was given as mainstay therapy. Lesions healed with characteristic cribriform scarring. CONCLUSION: This is a rare case of a Filipino child who initially manifested with pyoderma gangrenosum and eventually diagnosed with alpha-thalassemia trait. Due to serious cosmetic sequelae of pyoderma gangrenosum, it is important to find and treat the underlying systemic disorder to stop progression of this debilitating and disfiguring dermatosis

BACKGROUND

Superficial mycoses are one of the most common skin conditions encountered in the outpatient clinics, causing significant morbidity amongst patients. Since these are highly prevalent diseases of the skin, the general practitioner should be able to manage uncomplicated cases, with no need for evaluation by a specialist.

The study aimed to determine the knowledge, attitudes, and practices of Filipino medical interns on the management of superficial cutaneous mycoses using a self-administered questionnaire. This may help identify possible gaps in knowledge, as well as obstacles these future clinicians may encounter when managing superficial mycoses. This in turn may assist in the development or improvement of dermatology training among medical students and continuing medical education programs amongst non-dermatologist physicians.

This is a descriptive cross-sectional study among medical interns of the Philippine General Hospital to investigate their knowledge, attitudes, and practices regarding the management of superficial mycoses. Eligible participants were asked to complete an online self-administered survey questionnaire which assessed their capacity to recognize and manage uncomplicated superficial mycoses, and determined their attitudes regarding dermatology training in medical school.

The study included 170 medical interns, with majority having only 1-4 weeks of cumulative duration of dermatology training in medical school. Many of the participants (67.1%) had inadequate overall knowledge scores, but this was not significantly associated with their cumulative duration of dermatology training, as well as with their frequency of encounters with superficial mycosis patients. Most deem dermatology training (92.4%) and learning about the management of superficial mycoses (91.2%) during medical school very important. Majority are interested in attending more courses or training in the subject. Recommendations to improve medical school training on superficial mycoses include more practical approach in dermatology modules, integration of dermatology electives in medical school, and longer duration of dermatology modules/rotations during medical school.

While knowledge scores of medical interns were not significantly associated with the duration of their dermatology training during medical school as well as their encounters with patients with superficial mycoses, it is shown that they have low confidence scores regarding management of superficial mycoses. They deem that learning more about this disease and dermatology in general is vital to their medical education and are desirous of more training in this subject. Recommendations to improve medical school training on superficial mycoses include dermatology modules, rotations or electives in medical school. Additionally, better training during medical school, and formulation of clinical practice guidelines specific to cutaneous mycoses were recommended to improve healthcare delivery for patients with such diseases.

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

Psychodermatology is a field that focuses on the interaction of the skin and the mind. Psychodermatology patients are often challenging to manage because they often lack insight and are not amenable to psychiatric treatment or referral. Therefore, it is important that dermatologists become aware of the psychosocial impact of cutaneous disease and be knowledgeable in the fundamentals of psychodermatologic diagnosis and therapy. However, studies done in several countries report a general lack of perceived knowledge, awareness, and confidence in the management of psychodermatology disorders among dermatologists.

This study aims to determine the knowledge, attitudes, and practices of Filipino dermatologists towards psychodermatology using a self-administered questionnaire.

This is a mixed methods study using qualitative and quantitative measures. A self-administered questionnaire was validated and disseminated among the dermatologists in the country. Descriptive analysis was done.

Of the 153 participating dermatologists, majority (70.59%) reported psychodermatologic patients comprised < 10% of their practice. While more than half (56.2%) have a clear understanding of psychodermatology and are comfortable (57.52%) in approaching patients with these conditions, only 58 (37.91%) participants are able to demonstrate adequate knowledge on psychodermatology. Patients with primary psychiatric disorders are less frequently encountered than dermatologic disorders with psychiatric component or secondary psychiatric disorders. Most commonly prescribed medications are anti-histamines. Other psychotropic medications are rarely or never prescribed by the participants. All participants agree that psychodermatology is important in the practice of dermatology; 127 (62.1%) have attended at least one Continuing Medical Education (CME) on psychodermatology and 114 (74.51%) expressed willingness to attend CME training in psychodermatology. One hundred nine (71.24%) participants think that the best practice approach is a multidisciplinary approach to psychodermatology. The top recommendations for better healthcare delivery in psychodermatology were better access to mental health specialists (86.27%), more training opportunities and better training during residency (75.16%), and increase collaboration with psychiatrists (71.9%). The knowledge score was found to be associated with the duration of dermatology practice and attendance in CME proceedings but was not associated with the perceived adequacy of knowledge gained during training. Longer duration of practice may be associated with the knowledge score owing to the greater exposure to cases and more access to training opportunities.

There are many challenges to providing psychodermatologic care in the Philippines but the positive attitude towards psychodermatology, coupled with increased access to education and training opportunities, and the multidisciplinary approach to these cases may improve the quality of dermatologic care that we provide.

Chromoblastomycosis is an endemic mycoses which has been misdiagnosed or underdiagnosed in the past. This may be due to the clinicopathologic characteristics that it shares with other neglected tropical diseases such as leprosy and cutaneous tuberculosis. Correlating clinical findings with histopathologic cues will lead clinicians to correct diagnosis and subsequent treatment success.

Background: Herbal medicine is a growing and innovative field in Philippine dermatology. There is a need to assess the quality of reporting of published herbal randomized controlled trials (RCTs) in dermatology since these will serve to guide rational development and use of medicinal plants in the Philippines. Objective: The study aimed to assess the quality of reporting of published herbal RCTs in dermatology from the Philippines based on the hCONSORT checklist. Methods: We searched MEDLINE, CENTRAL, HERDIN (from inception to 20 September 2018), and other secondary sources for published randomized controlled trials that used any herbal preparation as intervention for the treatment or prevention of a dermatologic disease or for maintenance of healthy skin, hair, or nails. We determined the percentage of reported items based from the hCONSORT checklist. Results: We included 41 trials, majority of which were on infections, infestations, and bites (66%). The three most common families of herbs used were Fabaceae/Leguminosae (22%) (Gliricidia sepium (Jacq.) Walp. [kakawati]; Senna alata (L.) Roxb. / Cassia alata (L.) [akapulko]); Arecaceae (12%) (Cocos nucifera L. [coconut]); and Myrtaceae (12%) (Eucalyptus sp [eucalyptus], Psidium guajava L.[guava], and Melaleuca alternifolia (Maiden & Betche) Cheel [tea tree]). Most of the trials (27/41, 66%) were conducted in accredited dermatology training programs of the Philippine Dermatological Society. Only 11 trials (27%) were published in PubMED-indexed journals. More than half of articles were published after the CONSORT publication in 2006 (59%). The mean percentage of reported hCONSORT checklist items in included studies was 39.6% (SD 9.9), with only seven studies reporting more than 50% of the hCONSORT checklist items. Conclusion Published herbal RCTs in dermatology from the Philippines are poorly reported based on the hCONSORT checklist. There is a need for dissemination of the hCONSORT to local researchers and journal editors to ensure thorough and quality reporting.
