Palmoplantar psoriasis is a rare subtype of psoriasis. It is a chronic, relapsing, inflammatory, immunologically-mediated disease affecting the palms and soles.

This is a case of a 58-year-old female with multiple, well-defined, yellowish plaques on slightly erythematous base with some fissures on bilateral palmoplantar areas affecting 4% of body surface area. On Dermatology Life Quality Index, she scored 14. She was advised biopsy but deferred. The lesions were also tested with potassium hydroxide for fungal elements, yielding positive results. She was initially managed as tinea pedis et manuum with three pulse doses of oral antifungal medication for three months. With minimal improvement, patient finally consented for biopsy, confirming diagnosis of psoriasis. She was subsequently treated with potent topical corticosteroids and narrowband-ultraviolet B localized phototherapy, leading to a complete clearance of lesions after 16 weeks of steroid treatment and 52 sessions of phototherapy. There was no more erythema, plaques and fissures, with affected BSA down to 0% and DLQI score to 1. Three months post-treatment, there is still no recurrence of lesions.

Palmoplantar psoriasis is an uncommon variant of psoriasis featuring hyperkeratotic plaques and fissures limited to the palms and soles with associated significant functional impairment. It can be difficult to diagnose, often mistaken for other diseases, and is typically resistant to treatment with poor long-term remission. Biopsy plays a crucial part in the effective management especially among patients with refractory disease. There are numerous treatment modalities but psychosocial needs are equally important to be addressed.

Congenital syphilis is a worldwide public health concern. This occurs when an infected mother transmits the infection to the fetus during pregnancy or at birth.

We present a case of a 6-day-old male, term, born to a mother with secondary syphilis, via normal spontaneous delivery. Upon birth, patient was well and not in cardiorespiratory distress. However, cutaneous examination revealed multiple, well-defined vesicles and pustules on an erythematous background, some topped with erosions and crusts on the scalp, face, extremities, and trunk. Laboratory work-up and imaging were done which revealed congenital syphilis. He was managed with intravenous Penicillin (100,000iu) 160,000 IV for ten days, and wound healing was hastened by use of a coconut-based cellulose wound dressing on the erosions. He was then referred to a multispecialty team to assess and co-manage possible complications. Regular interval follow-up and repeat laboratory tests were advised for observation and for monitoring.

Congenital syphilis is caused by the bacterium Treponema pallidum. Sequelae include preterm birth, low birth weight, skin lesions, bone deformities, hepatosplenomegaly, anemia, and neurological problems. Diagnosis can be made on clinical suspicion combined with Rapid Plasma Reagin (RPR) and Venereal Disease Research Laboratory (VDRL). Aside from Penicillin G, wound care, nutritional build up, and close monitoring of growth and development with regular follow-ups are essential aspects in the management of congenital syphilis. With timely and adequate treatment, infants have a higher likelihood of complete resolution of symptoms, prevention of long-term complications, and improved overall health outcomes.

Psoriasis may manifest as severe hyperkeratotic lesions resembling an oyster shell called ostraceous psoriasis. This type of psoriasis is extremely rare and is often associated with psoriatic arthritis. Psoriatic arthritis is a chronic inflammatory disease of the joints presenting with pain, stiffness, swelling, tenderness, and limited movements. This is a case of a 16-year-old Filipino female presenting with pruritic erythematous plaques topped with thick adherent ostraceous scales associated with bilateral knee and elbow pains. Laboratory tests and biopsy were done. Histopathology is consistent with psoriasiform dermatitis and psoriatic arthritis is established through Early Psoriatic Arthritis (EARP) Screening Questionnaire and Classification Criteria for Psoriatic Arthritis (CASPAR). Patient was started on potent topical corticosteroids and Narrow-band Ultraviolet B (NB-UVB) phototherapy with minimal improvement. Hence, Secukinumab was initiated which showed significant improvement on the skin lesions and joint pains 7 days after the first dose of Secukinumab. Ostraceous psoriasis is rarely found in pediatric population. It is commonly associated with psoriatic arthritis that should be screened during routine consult. Its characteristic firmly adherent thick scales are resistant to topical treatments. One of the therapeutic options is Secukinumab, an IL-17A selective inhibitor targeting the release of proinflammatory cytokines, chemokines and mediators of tissue damage. It demonstrates immediate effect, significant and sustained improvement in the skin lesions, minimal adverse reactions, as well as improved quality of life and physical function. It is therefore a preferred treatment for patients with moderate to severe psoriasis and psoriatic arthritis requiring rapid clearance.

BACKGROUND

Narrow-band ultraviolet B (NB-UVB) phototherapy is a mainstay in the treatment of psoriasis, with dosage related to the minimal erythema dose (MED), with initial dose at 50-70%, followed by dose increments.

OBJECTIVE

To determine the MED of Filipino adult patients with psoriasis using NB-UVB phototherapy at a tertiary government hospital.

METHODOLOGY

This is an analytical, observational, cross-sectional study with prospective data collection among Filipino adults with psoriasis, at Dr. Jose N. Rodriguez Memorial Hospital and Sanitarium, from March 2023 to June 2024. Participants underwent MED determination using NB-UVB phototherapy cabinet. MED was defined as the square with definite redness, very light pink, or faintly detectable erythema over the entire exposed site after 24 hours. Clinicodemographic information were gathered and analyzed for possible associations with obtained MED.

RESULTS

Forty-eight participants were enrolled with MED as follows: 600 mJ/cm² (47.92%), 800 mJ/cm² (25%), 1000 mJ/cm² (12.50%), 1200 mJ/cm² (10.42%), and 400 mJ/cm² (4.17%). Age appeared to be directly proportional to MED dose (p-value =0.047). A statistically significant association of having lower MED values (p=0.017) were observed in patients with concomitant diabetes mellitus. Sex, Fitzpatrick skin type, psoriasis severity, and the body site used for testing, had no association with obtained MED values.

CONCLUSION

The median MED was 600 mJ/cm². Based on this, the suggested initial dosage of NB-UVB at 50-70% is 300-420 mJ/cm². These findings demonstrate that the current starting dose being used at DJNRMHS can either be maintained at 300 mJ/cm² or can be safely increased up to 420 mJ/cm².
