Cutaneous larva migrans imported from a tropical trip - Case report and literature review.

INTRODUCTION: Cutaneous larva migrans (CLM) is a zoonotic disease caused by hookworms characteristic of tropical and subtropical regions. In Poland, new cases appear every year in patients who have travelled to tropical areas. Most of the cases are initially under-diagnosed, which results in a delay in starting proper treatment. CASE REPORT: A 49-year-old woman presented to the Outpatient Dermatology Clinic with a pruritic and fibrous cutaneous lesion on the plantar region of her left foot. She had returned from a tourist trip to Honduras one week before the skin lesion erupted. RESULTS: The diagnosis of CLM due to Ancylostoma sp. infestation was confirmed. Locally applied cryotherapy was ineffective. The oral treatment of albendazole resulted in complete resolution of the symptoms without recurrence after a 6-month follow up period. CONCLUSIONS: CLM should be considered in travellers to tropical countries. Oral anti-parasitic agents seem to be more effective than topical treatment for dermatosis.

Comparative Efficacy of Topical Pertmehrin, Crotamiton and Sulfur Ointment in Treatment of Scabies.

BACKGROUND: Scabies is an ectoparasitic infection, which occurs because of direct skin-to skin contact. The ideal treatment modality is still unclear and further research on this topic is warranted. The aim of the study was to compare the efficacy and safety of the topical scabicides: permethrin, crotamiton and sulfur ointment. METHODS: Fifty four patients with diagnosed scabies were randomly divided into three treatment groups. The first group received 5% permethrin cream twice with one week interval, the patients from the second group were given crotamiton lotion for two days twice with one week interval, while the third group received 10% sulfur ointment for two or three weeks. All patients were followed up at 1, 2 and 4 weeks intervals. RESULTS: At one-week follow up the cure rate was significantly higher at permethrin-treated group when compared to crotamiton group (P< 0.001) and sulfur group (P< 0.001). At the end of two-week interval, the cure rate at permethrin group was 100%, while at crotamiton group, 66.7% and in sulfur group 38.9% (P< 0.001). At 4-week follow up the applied treatment was effective in all studied individuals. CONCLUSION: The topical application of permethrin, crotamiton and sulfur was equally efficacious at 4-week follow up, however permethrin cream showed faster improvement at first and second follow up. Acquiring permethrin is considered as expensive option and crotamiton lotion seems to be cost-less alternative to this cream.

The prevalence of mutations in the gene encoding filaggrin in the population of Polish patients with atopic dermatitis.

INTRODUCTION: The genetic background of atopic dermatitis (AD) is complex, involves many genes and their participation varies in varied populations, and depends on the intensity and course of a disease. Changes in the nucleotide sequence of the FLG gene and a reduced number or a deficit of the functional product of processed profilaggrin can be one of risk factors for atopic dermatitis. AIM: To determine the prevalence of R501X and 2282del4 mutations of the FLG gene in patients with AD. MATERIAL AND METHODS: The studied group included 60 patients with clinically diagnosed AD, and the control group included 61 healthy volunteers. The study protocol included collection of biological material for tests, DNA isolation and evaluation of its quality and quantity, and PCR amplification of the isolated genetic material. RESULTS: In the studied group, both changes in the nucleotide sequence of the FLG gene were detected and in the control group no tested mutations were detected. In 18 (30%) patients with AD, 22 mutations (4 heterozygous and 1 homozygous ones of R501X and 10 heterozygous and 7 homozygous ones of 2282del4) were detected. CONCLUSIONS: A high rate of mutations of the FLG gene in patients with clinically diagnosed AD and pathologically dry skin was observed in the studied population. The 2282del4 mutation occurred more often than R501X.
