Scabies: Epidemiology, Diagnosis, and Treatment
Dtsch Arztebl Int 2021 Oct 15;118(41):695-704.PMID:34615594DOI:10.3238/arztebl.m2021.0296.
Background: Scabies is a skin infestation whose incidence is apparently rising. Methods: This review is based on pertinent articles retrieved by a selective search of PubMed on diagnosis and treatment strategies. Results: Thread-like papules (burrows), new, intense pruritus, and dermatitis guide the suspected diagnosis which is confirmed by the microscopic or dermatoscopic demonstration of scabies mites. The first line therapy is topical application of permethrin, in accordance with the current recommendations for its use. Other treatment options include systemic ivermectin and topical crotamiton or Benzyl benzoate. A combination of permethrin and ivermectin is used to treat otherwise intractable cases and is generally indicated for the treatment of crusted scabies. Known causes of treatment failure include improper application of the external agents, failure of repeated treatment with ivermectin, incomplete decontamination of furnishings and clothes, failure to simultaneously treat contact persons, absence of written documents explaining treatment modalities, and the patient's belonging to a risk group. Even though there has not yet been any direct proof of resistance of scabies mites to permethrin, there is a rising number of welldocumented cases of poor response to this agent. Moxidectin is a new substance now undergoing clinical testing. Conclusion: Treatment of scabies according to the guidelines and the additional recommendations reported here should result in effective curing, even in cases that are thought to be intractable.
Safety Assessment of Benzyl Alcohol, Benzoic Acid and its Salts, and Benzyl benzoate
Int J Toxicol 2017 Nov/Dec;36(3_suppl):5S-30S.PMID:29243541DOI:10.1177/1091581817728996.
Benzyl alcohol, benzoic acid and its salts, and Benzyl benzoate function mostly as fragrance ingredients/preservatives in cosmetic products. The Cosmetic Ingredient Review Expert Panel previously established concentration limits for benzyl alcohol, benzoic acid, and sodium benzoate in cosmetics and determined that the available data were insufficient to support the safety of these ingredients during inhalation exposure. After reviewing newly available data, it was concluded that benzyl alcohol, benzoic acid and its salts, and Benzyl benzoate are safe in the present practices of use and concentration described in this safety assessment.
European guideline for the management of scabies
J Eur Acad Dermatol Venereol 2017 Aug;31(8):1248-1253.PMID:28639722DOI:10.1111/jdv.14351.
Scabies is caused by Sarcoptes scabiei var. hominis. The disease can be sexually transmitted. Patients' main complaint is nocturnal itch. Disseminated, excoriated, erythematous papules are usually seen on the anterior trunk and limbs. Crusted scabies occurs in immunocompromised hosts and may be associated with reduced or absent pruritus. Recommended treatments are permethrin 5% cream, oral ivermectin and Benzyl benzoate 25% lotion. Alternative treatments are malathion 0.5% aqueous lotion, ivermectin 1% lotion and sulphur 6-33% cream, ointment or lotion. Crusted scabies therapy requires a topical scabicide and oral ivermectin. Mass treatment of large populations with endemic disease can be performed with a single dose of ivermectin (200 micrograms/kg of bodyweight). Partner management needs a look-back period of 2 months. Screening for other STI is recommended. Patients and close contacts should avoid sexual contact until completion of treatment and should strictly observe personal hygiene rules when living in crowded spaces. Written information should be provided to suspected cases.
Toxicity of Benzyl benzoate as a food additive and pharmaceutical agent
Toxicol Ind Health 2022 Apr;38(4):221-233.PMID:35332820DOI:10.1177/07482337221086133.
Benzyl benzoate (BB), one of the benzyl derivates, is a component of brown aromatic resin in cinnamon oil and cough syrups and it is widely used in various fields in the perfume, pharmaceutical, and food industries. It is absorbed and hydrolyzed to benzoic acid and benzyl alcohol. Two different doses of BB (25 mg kg-1 body weight and 100 mg kg-1 body weight) were orally administered to 5-week old male rats for 90 days. Histopathological, morphological, hematological, and biochemical assays were performed in toxicological evaluations. Initial/final body weights, relative organ weights, and food and water consumptions of rats did not change significantly. There were statistically significant differences in terms of monocyte, neutrophil, lymphocyte %, and serum AST levels in control and BB treatment groups. Several histopathological findings were observed in liver, kidney, thymus, prostate, and epididymis tissues of the rats in the treatment groups. Immunohistochemical examinations were also performed in the tissues for fibronectin (FN), type IV collagen, transforming growth factor β (TGF-β), matrix metalloproteinase-2 (MMP-2), and tissue inhibitor of metalloproteinase-2 (TIMP-2). Alterations in immunolocalization of these markers were observed between the control and the treatment groups. No changes were detected in the sperm count, daily sperm production, and sperm morphology.
The Treatment of Scabies
Dtsch Arztebl Int 2016 Nov 14;113(45):757-762.PMID:27974144DOI:10.3238/arztebl.2016.0757.
Background: Scabies is a contagious infestation transmitted by skin-to-skin contact and sometimes by contact with contaminated material. The scabies mite burrows into the skin, producing a papular rash and severe itch at typical sites of predilection. Methods: We systematically reviewed the literature to compare the efficacy of various anti-scabies agents, including a calculation of relative risks and confidence intervals. Results: A literature search yielded 596 initial hits; after screening in accor-dance with the defined inclusion and exclusion criteria, 16 studies were selected for this review. Among topical treatments for scabies, permethrin was equally effective or more effective than crotamiton or Benzyl benzoate. In a comparison of topical versus systemic treatment, topical permethrin and systemic ivermectin did not differ substantially in efficacy (7 comparative studies revealed no difference; one revealed a difference in favor of permethrin). Comparative trials of topical Benzyl benzoate versus systemic ivermectin yielded inconsistent findings. Single and double administrations of ivermectin were similarly effective. In trials involving entire populations with a high prevalence of scabies, systemic ivermectin was found to be superior to topical permethrin. Conclusion: There are hardly any differences in efficacy between the available treatments for scabies. Single administrations of permethrin 5%, crotamiton 10%, and systemic ivermectin are all comparably effective. There are differences in the frequeny and ease of application as well as when eradicating scabies in populations with a high prevalence.
