Lupus eritematoso neonatal. Reporte de caso de lactante concebida por inseminación artificial y madre con artritis reumatoidea / Lupus eritematoso neonatal Report of the infant case conceived by artificial insemination and mother with rheumatoid arthritis

El Lupus Eritematoso Neonatal es una enfermedad de origen autoinmune caracterizada por rash cutáneo transitorio, bloqueo cardíaco congénito permanente, función hepática anormal con o sin enfermedad biliar y compromiso hematológico asociado a la presencia de autoanticuerpos maternos contra la ribonucleoproteinas solubles (SSB/La, SSA/Ro y Anti-RNP). Se presenta el caso de una niña de cinco meses de edad con hallazgos clínicos e histopatológicos de Lupus eritematoso neonatal. Es una condición que no suele dejar secuelas, aunque se han reportado casos de atrofia cutánea e hiperpigmentación

Neonatal Lupus Erythematosus is an autoimmune disease characterized by transitory cutaneous rash, congenital heart block, abnormal liver function test with or without cholestasis and hematologic features associated to anti-Ro and anti-La autoantibodies. A 5-month-old female is brought to the hospital with clinical and histopathology findings of Neonatal lupus. This medical condition does not leave long term physical damage, however there have been cases reported with cutaneous atrophy and hyperpigmentation

Results of a Phase 2 Efficacy and Safety Study with SB204, an Investigational Topical Nitric Oxide-releasing Drug for the Treatment of Acne Vulgaris.

OBJECTIVE: To compare efficacy, tolerability, and safety of two concentrations of topical SB204 and vehicle twice daily for 12 weeks in the treatment of acne vulgaris. DESIGN: Randomized, double-blind, placebo-controlled, three-arm, Phase 2 study. SETTING: Dominican Republic, Panama, and Honduras. PARTICIPANTS: Subjects with acne, age 12 to 40, with 25 to 70 noninflammatory lesions, 20 to 40 inflammatory lesions, and a baseline Investigator's Global Assessment score of mild, moderate, or severe. MEASUREMENTS: The primary efficacy assessment was the absolute change in noninflammatory lesion counts. Other assessments included inflammatory lesion counts, success on dichotomized Investigator's Global Assessment, reported adverse events, physical examinations, laboratory testing, and tolerability. RESULTS: One hundred fifty-three subjects were randomized to vehicle (n=52), SB204 1% (n=51), or SB204 4% (n=50). When compared to vehicle, subjects treated with SB204 1% and SB204 4% had significantly greater mean percent reduction in noninflammatory lesions from baseline and subjects treated with SB204 4% had a significantly greater mean percent reduction in inflammatory lesion count from baseline at Week 12. There were no significant differences in the IGA success rates between groups. Both concentrations of SB204 were safe and well-tolerated. CONCLUSIONS: When compared to vehicle, both SB204 1% and SB204 4% significantly decreased the percentage of noninflammatory lesions and SB204 4% also significantly decreased the percentage of inflammatory lesions in subjects with acne vulgaris treated for 12 weeks. Treatment with SB204 1% and SB204 4% was safe and well-tolerated. Registry: clinicaltrials.gov (NCT01844752).

A prospective two-year assessment of miconazole resistance in Candida spp. With repeated treatment with 0.25% miconazole nitrate ointment in neonates and infants with moderate to severe diaper dermatitis complicated by cutaneous candidiasis.

A petrolatum and zinc oxide-based ointment containing 0.25% miconazole nitrate is reported to be effective and well tolerated in the treatment of diaper dermatitis complicated by cutaneous candidiasis (DDCC). This prospective, multicenter, open-label, long-term, phase IV study investigated the potential resistance of Candida spp. to repeated topical use of 0.25% miconazole nitrate in infants age 15 months and younger with moderate to severe DDCC. For initial and recurring episodes of DDCC over the 2-year study period, subjects were treated with a 7-day course of 0.25% miconazole nitrate ointment (active components: miconazole nitrate 0.25%, zinc oxide 15%, and white petrolatum 81.35%) with a 7-day follow-up. Clinical and mycologic evaluations were conducted before treatment (day 0) and 7 days after treatment (day 14). Potential resistance to miconazole was defined using an arbitrary breakpoint of minimum inhibitory concentration of 2 µg/mL. There was no evidence of resistance to miconazole in Candida spp. after single or repeated treatment courses of 0.25% miconazole nitrate ointment. For the initial episode of DDCC, 83 of 168 subjects (49.4%) achieved a clinical cure, 77 (45.8%) achieved a mycologic cure, and 49 (29.2%) achieved an overall cure (clinical and mycologic). The overall cure rate for recurrent episodes of DDCC was similar to or numerically greater than rates observed for the initial episode. Treatment of DDCC with 0.25% miconazole nitrate ointment was effective and generally well tolerated. No evidence of the development of resistance to miconazole in Candida spp. was observed.

NVC-422 topical gel for the treatment of impetigo.

Impetigo is a highly contagious bacterial skin infection affecting children worldwide that is caused by the Gram-positive bacteria Staphylococcus aureus, Streptococcus pyogenes, or both. Staphylococcus species can quickly develop drug resistance rendering mupirocin, fusidic acid, and erythromycin ineffective. Preclinical and clinical studies demonstrated that NVC-422 (N, N-dichloro-2, 2-dimethyltaurine) rapidly kills pathogens without the development of drug resistance. 129 patients with clinically diagnosed impetigo were randomized to three dose groups (0.1, 0.5, or 1.5% NVC-422 topical gel) in a study conducted at 2 centers; 125 patients (97%) had microbiologically confirmed infection. Treatment was administered three times a day (TID) for 7 days to all randomized subjects. Response was measured at the completion of treatment (Day 8) and 1 week post treatment (Day 15) by the Skin Infection Rating Scale (SIRS) and by microbiological response. A total of 120 subjects (96%) completed all 7 days of treatment and were assessed at end of treatment (EOT). Clinical response rate at EOT in the PPC population was excellent in each of the dose groups (84.6%, 87.2%, and 92.3% in the 0.1%, 0.5% and 1.5% dose groups respectively). The majority of the infections were caused by S. aureus, alone (106/125, 85%) of which approximately 10% were MRSA. There were no clinical recurrences in any treatment groups. Treatment-emergent adverse events were seen in 5.4% of the subjects (7/129) and were mild to moderate and resolved. NVC-422 topical gel administered TID was well tolerated, with high rates of clinical and microbiological responses for treating impetigo.
