Effect of the Intralesional Forms of Methylprednisolone Acetate and Methotrexate on Psoriatic Nails.

Individuals with psoriatic nails often have a lower quality of life relative to their counterparts with healthy nails. Methotrexate (MTX), an anti-neoplastic agent, is a longstanding treatment option for nail psoriasis. In the current study, we compared the effects of MTX to that of a corticosteroid, namely, methylprednisolone acetate (i.e., Depo-Medrol®) across individuals with nail psoriasis. We used a cohort study design, and both agents were administered intralesionally. Outcome variables were based on the Nail Psoriasis Severity Index (NAPSI). We quantified the effect in terms of change in NAPSI, complete cure at week 16, and cure between 32 and 36 weeks. Our regressions demonstrated that reduced NAPSI scores with Depo-Medrol were, on average, greater than that with MTX by 2.27 (n = 48, P = 0.000255) at week 16. Similarly, the odds of complete cure at week 16 was greater with Depo-Medrol® than with MTX (odds ratio = 18.6, P < 0.0001). In terms of both complete cure and change in NAPSI, Depo-Medrol® was significantly more effective than MTX at a follow-up period of 32-36 weeks. Our study established that intralesional Depo-Medrol® is more effective than intralesional methotrexate for treating nail psoriasis.

Biological treatment for bullous pemphigoid.

Background: Bullous pemphigoid (BP) is the most common autoimmune subepidermal bullous disease. Topical or systemic corticosteroids are often used as the first-line treatment. However, long-term corticosteroid use may lead to significant side effects. Therefore, various adjuvant immunosuppressant therapies are used as steroid-sparing agents, with accumulating reports of biological treatments for severely recalcitrant BP. Objective: To describe the clinical and immunological features of a series of patients with recalcitrant BP treated with immunobiological therapies. To assess the efficacy and safety of their therapies. Methods: Patients receiving biological treatment for BP from two centers were assessed. Here, we described the clinical, immunopathological, and immunofluorescence findings of adult patients with BP and analyzed the clinical response and adverse events associated with various biological therapies. Results: We identified nine eligible patients treated with rituximab (seven), omalizumab (three), or dupilumab (one). The mean age at diagnosis was 60.4 years, the average BP duration before biologic initiation was 1.9 years, and the average previous treatment failure was 2.11 therapies. The mean follow-up period from the first biological treatment to the last visit was 29.3 months. Satisfactory response, defined as clinical improvement, was achieved in 78% (7) of the patients, and total BP clearance was achieved in 55% (5) of the patients at the last follow-up visit. Additional rituximab courses improved the disease outcomes. No adverse events were reported. Conclusions: Efficient and safe novel therapies can be considered in recalcitrant steroid-dependent BP non-responsive to conventional immunosuppressant therapies.

Diagnostic approach to tinea capitis with kerion: A retrospective study.

BACKGROUND: Kerion is an inflammatory type of tinea capitis manifesting as boggy crusted nodules. Diagnosis of kerion is often challenging due to high rates of false-negative mycological samples. METHODS: A retrospective study among children with kerion, prior to antifungal treatment, was conducted to assess rates of false-negative mycological samples. Specimens for direct microscopy and fungal culture were collected at baseline and after administration of an oral antibiotic course, with or without an oral steroid course. Kerion was categorized as highly inflammatory when a painful, moist scalp nodule with spontaneous purulent discharge or exuberant crust was present, or mildly inflammatory when an erythematous, dry scalp nodule was seen. RESULTS: Twenty-three children (mean age 7.9 ± 3.0 years) were included in the study. Trichophyton tonsurans was the most common species isolated (69.6%). Highly inflammatory kerions were significantly more likely to be culture negative before treatment than mildly inflammatory kerions (80% vs. 16.7%, p < .01). Non-inflammatory tinea capitis lesions (n = 13) were culture positive in all cases. Following a combined oral antibiotic and steroid course given to most highly inflammatory kerions (n = 11/13), higher rates of positive fungal cultures were found compared to baseline (90.9% vs. 18.2%, p < .01). CONCLUSION: High rates of negative fungal cultures were found only in highly inflammatory kerion. Sampling a highly inflammatory kerion after a combined oral antibiotic and steroid course improved rates of positive fungal cultures. In addition, sampling of non-inflammatory tinea capitis lesions (when present in addition to the kerion) had the highest culture sensitivity.

Efficacy of Fluocinonide\Bifonazole Cream for the Treatment of Trachyonychia: A Retrospective Case Series.

Background: Trachyonychia is a benign nail condition, most commonly seen in children. Trachyonychia manifests as excessive longitudinal ridging, nail roughness, and nail brittleness. Treatment is sought mainly for esthetic reasons as well as functional reasons. A number of therapeutic approaches exist, mainly based on case reports or small non-comparative case series. Aims: To report treatment outcome among patients with trachyonychia. Methods: A retrospective case-series study was conducted among patients who were treated trachyonychia between years 2017 and 2020. Patients were prescribed fluocinonide 0.05% with bifonazole 1% cream, applied with or without occlusion, and methylprednisolone 1-2 mg/nail, injected into the involved nail matrix, or oral cyclosporine 3 mg/kg. Complete response (over 90% improvement) and partial response (over 50% improvement) were assessed. Results: A total of 43 patients with trachyonychia were included [mean age 10.0 years (±5.7), 69.8% males, mean disease duration 4.7 years (±3.0)]. In 90.7% of the cases, topical fluocinonide\bifonazole cream was prescribed. Under-occlusion topical application was found to be highly effective, achieving complete response in 35.3% and partial response in an additional 52.9% of the patients. Occluded application was also found to be significantly more effective than non-occluded application. Treatment efficacy was not affected by the severity of nail roughness, trachyonychia morphology, or whether trachyonychia was idiopathic or coexisted with other dermatological conditions. Conclusion: Occluded application of fluocinonide plus bifonazole cream is efficient for the treatment of trachyonychia and should be considered a first line of treatment.

Liquid nitrogen: temperature control in the treatment of actinic keratosis.

BACKGROUND: Actinic keratoses (AKs) are in situ epidermal tumors that may progress to invasive squamous cell carcinomas. Liquid nitrogen is used during cryotherapy to freeze the epidermis and upper dermis and is the standard treatment for individual AKs. OBJECTIVE: To evaluate the efficacy of a cryosurgery device incorporating an infrared sensor to measure the temperature at the skin surface while spraying liquid nitrogen on the surface of the skin during the treatment of AKs. METHODS & MATERIALS: Thirty-six patients with 180 thin AKs were treated with liquid nitrogen spray to a temperature of -5°C using the sensor to control the temperature at the skin surface. Patients were evaluated for cure rate, side effects, and healing time. RESULTS: At the 1-week follow-up, 66.7% of the lesions were cleared. By the 6-week follow-up, there was a 100% cure rate. Side effects were limited to redness, blistering, crusting, oozing, and ulceration at the 1-week follow-up and were resolved by the 6-week follow-up. No recurrence of AK, scarring, or hypopigmentation was noted. CONCLUSION: Cryotherapy with an integrated sensor for temperature control is an effective, safe, and precise treatment, allowing for a 100% short-term cure rate of AKs.

Treatment of moderate to severe facial seborrheic dermatitis with itraconazole: an open non-comparative study.

BACKGROUND: Seborrheic dermatitis is a common chronic disease. Malassezia yeasts have been implicated in the pathogenesis of this disease. Antifungal agents are known to be effective in the treatment of Malassezia yeast infections. OBJECTIVES: To evaluate the efficacy of itraconazole in the treatment of mild to severe facial seborrheic dermatitis. METHODS: Sixty patients with moderate to severe seborrheic dermatitis were evaluated in an open non-comparative study. Patients were treated with oral itraconazole, initially 200 mg/day for a week, followed by a maintenance therapy of a single dose of 200 mg every 2 weeks. Four clinical parameters (erythema, scaling, burning, itching) were assessed using a 0-3 score. Mycological evaluation determined the presence of Malassezia spores in the scales using a direct smear. RESULTS: At the end of the initial treatment significant improvement was reported in three clinical parameters: erythema, scaling, itching. Maintenance therapy led to only slight further improvement. Burning sensation was only mildly improved during the treatment. The quantity of Malassezia spores present in the direct smear decreased throughout the treatment period. No blood test abnormalities were found during the treatment. CONCLUSIONS: In this study initial treatment with itraconazole was beneficial in patients with moderate to severe seborrheic dermatitis.

Measuring alterations in intra-abdominal pressure during abdominoplasty as a predictive value for possible postoperative complications.

The purpose of this study was to measure the changes in Intra-Abdominal Pressure (IAP) during abdominoplasty and the relevance of these changes to the immediate postoperative recovery period. Eighteen patients (17 females and one male) who underwent abdominoplasty for aesthetic reasons participated in the study. The data collected included measurements of height, weight, and measurements of the intra-urinary bladder pressure prior to surgery, immediately post operative, and 18-24 hours postoperative. Changes in tidal volume and ventilation pressures were also measured prior to surgery and immediately postoperative. The weight of the excised tissue ranged between 1150 g-6500 g with an average of 2700 g. Three patients had significant diasthesis recti repair during surgery. In these patients the measured intra-vesicular pressure was above 24 cm of H(2)O by the end of the operation and above 20 cm of H(2)O the day following surgery. Two out of the three patients were treated with anticoagulants and the symptoms subsided within a week. The third patient recovered spontaneously by the third day. In conclusion, patients with an intra-urinary bladder pressure above 20 cm of H(2)O following abdominoplasty were felt to be at significant risk for development of respiratory distress in the immediate postoperative period.
