BackgroundWe report the first successful treatment of limbal lesions and corneal erosion experienced by a breast cancer patient undergoing trastuzumab treatment.Case presentationA 49-year-old Caucasian woman with early stage breast cancer was treated with adjuvant trastuzumab and subsequently showed persistent bilateral corneal marginal infiltrates resistant to topical steroid and antibiotic treatment. Autologous serum was applied in the conjunctival sac as an experimental treatment to antagonize the inhibitory effect of the HER2 receptor antibody on the corneal epithelial cells. Topical application of autologous serum led to rapid improvement of the ulcerative keratitis, with complete healing of the corneal defect after 7 days. Continued administration of the serum allowed the resumption of trastuzumab therapy without any further side effects.ConclusionsPersistent bilateral corneal marginal infiltrates may occasionally arise as a side effect of trastuzumab treatment. Topical medication with autologous serum may be an effective therapeutic option for the ocular side effects of trastuzumab therapy.
Purpose. To report the risk of methicillin-resistant Staphylococcus aureus (MRSA) ocular infection after UVA-riboflavin corneal collagen cross-linking in a patient with atopic dermatitis. Methods. A 22-year-old man, with bilateral evolutive keratoconus and atopic dermatitis, underwent UVA-riboflavin corneal cross-linking and presented with rapidly progressive corneal abscesses and cyclitis in the treated eye five days after surgery. The patient was admitted to the hospital and treated with broad-spectrum antimicrobic therapy. Results. The patient had positive cultures for MRSA, exhibiting a strong resistance to antibiotics. Antibiotic therapy was modified and targeted accordingly. The intravitreal reaction is extinguished, but severe damage of ocular structures was unavoidable. Conclusion. Riboflavin/UVA corneal cross-linking is considered a safe procedure and is extremely effective in halting keratoconus' progression. However, this procedure is not devoid of infectious complications, due to known risk factors and/or poor patients' hygiene compliance in the postoperative period. Atopic dermatitis is a common disease among patients with keratoconus and Staphylococcus aureus colonization is commonly found in patients with atopic dermatitis. Therefore, comorbidity with atopic dermatitis should be thoroughly assessed through clinical history before surgery. A clinical evaluation within three days after surgery and the imposition of strict personal hygiene rules are strongly recommended.
The relationship between genetic polymorphisms and migraine as a cause of an increased risk of thrombotic disorders development is still debated In this respect, factor V Leiden, factor V (H1299R), prothrombin G20210A, factor XIII (V34L), β-fibrinogen, MTHFR (C677T), MTHFR (A1298C), APO E, PAI-1, HPA-1 and ACE I/D seem to play a determinant role in vascular diseases related to migraine. The present review analyzes both the incidence of the above genetic vascular mutations in migraineurs and the most re-cent developments related to genetic polymorphisms and migraine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
