- Periocular basal cell carcinoma: cost of topical immunotherapy versus estimated cost of surgical treatment(2012) MACEDO, Erick Marcet Santiago de; CARNEIRO, Rachel Camargo; CARRICONDO, Pedro Carlos; MATAYOSHI, SuzanaPurpose: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. Methods: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of Sao Paulo (HC-FMUSP, Brazil). The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. Results: Immunotherapy lasted from 8 to 12 weeks. All patients reported each cold-stored sachet with 5% imiquimod cream lasted 3 days. According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.40-1,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. Conclusions: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns. The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions. Further studies should evaluate the possibility of institutions equating the cost of immunotherapy and surgical treatment by acquiring similar but less expensive medications.
- Efficacy of mitomycin C in modified transcanalicular diode laser dacryocystorhinostomy(2022) FEIJÓ, Eduardo Damous; DIAS, Mirna de Melo; SOUZA, Bruna Angelina Alves de; CAIXETA, Juliana Alves; LIMONGI, Roberto Murillo; MATAYOSHI, SuzanaABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.
- Reconstrução total de pálpebra superior no tratamento do carcinoma de glândula sebácea(2020) VERAS, Deborah de Oliveira; GUMIERO, Mariana Pereira Leite Dias; BAPTISTA, Mariana Nóbrega Meireles; MATAYOSHI, SuzanaAbstract Sebaceous gland carcinoma (SGC) is the third most frequent malignant neoplasm in the eyelids. It usually affects elderly women and can simulate blepharitis or chalazion. Upper eyelid reconstruction is always challenging. The purpose of this is to report an unusual case of SGC in the upper eyelid of a young and male patient. Total resection of the right upper eyelid was performed and histological examination revealed free margins. The reconstruction was done with two surgical procedures at different times. Due to the fact that SGC presents a high potential for metastasis, the patient continues to be followed for functional and aesthetic reevaluation.
- O uso de enxerto e retalho de periósteo em Oftalmologia(2019) BACCEGA, Felipe; MATAYOSHI, Suzana; NASCIMENTO, Maria Antonieta da Anunciação GinguerraAbstract Purpose: The authors reviewed the periosteum use in ophthalmic surgery and its results. Methods: A comprehensive review of the literature using Google Scholar, PubMed and SciElo databases with all articles about the periosteum use in Ophthalmology published from 1977 to 2018. Results: A total of 21 studies followed the review's purpose: 9 case reports, 9 case series, 1 retrospective cohort and 2 prospective cohorts. 206 patients were submitted to the procedures with the periosteum use in the two main forms: graft and flap. The principal reasons for periosteal use were: orbital implant covering and eyelid reconstruction. Surgical outcomes were very satisfactory with low complication rates of 10.67% and minimal necessity of new surgical intervention of 2.42%. Conclusion: The periosteum use in Ophtalmology is a promising technique with good results so far and should always be a therapeutic option for the ophthalmologist. However, based on available data in the literature, more studies with statistical power for knowledge sedimentation in this subject are recommended.
article 0 Citação(ões) na Scopus Analysis of corneal keratometry in patients with hemifacial spasm(2011) PEREIRA, Ivana Cardoso; SARAIVA, Patricia Grativol Costa; SARAIVA, Fabio Petersen; MEDEIROS, Fabricio Witzel de; MIKI, Gustavo; MATAYOSHI, SuzanaPurpose: To determine the corneal keratometric variation in patients' eyes with unilateral hemifacial spasm which underwent treatment with botulinum toxin and set against control group. Methods: Eighteen patients with hemifacial spasm were submitted to complete ophthalmologic exam, corneal topography and Orbscan previously botulinum toxin application and one month afterwards. They were evaluated for keratometry, BFS (anterior and posterior) and Roush value. Results: There were no statistical differences between eyes with hemi facial spasm and normal eyes related to keratometric values by topography and in the parameters evaluated by Orbscan as Roush and best fit sphere (anterior or posterior) prior to or after treatment with botulinum toxin. Conclusion: This study has not shown statistical difference between the corneal curvatures when compared eyes with hemi facial spasm with the opposite normal eyes.- Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis(2018) FEIJÓ, Eduardo Damous; ALMEIDA, Adriana Ribeiro de; MATAYOSHI, SuzanaAbstract We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin's Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.
- Acurácia do exame clínico no diagnóstico de lesões palpebrais(2014) ROSSATO, Luiz Angelo; CARNEIRO, Rachel Camargo; MIYAZAKI, Ahlys; MATAYOSHI, SuzanaObjective: To analyze the accuracy of the clinical examination in the diagnosis of eyelid lesions. Methods: From the observation of thirtyfive photos of benign and malignant eyelid tumors were presented to ophthalmologists, for each picture, it was asked 3 questions: 1) the lesion is malignant or not; 2) if considered malignant, the probably histological type; and 3) the tumor is aggressive or not. The phisicians were divided into 9 groups, according to academic degree (time since graduation and Oculoplastics specialty or not). Answers were compared with the results of the histopathologic study of the surgically resected tumor. Results: In total, one hundred and six ophthalmologists were interviewed. The professional experience influenced the diagnosis of malignancy of the tumor, as the Group 1 (first year residents) had the lowest accuracy (64.5%), with lower estimated agreement (kappa = 0.13), and Group 5 (graduated 5 years ago and with expertise in Oculoplastics) the highest accuracy (77.3%), with better agreement (Kappa = 0.45), and presented the best parameters for other analyzed items. For the histological type diagnosis, accuracy was lower: group 1 had the worst performance, with 51.1% accuracy, while the best was for group 6 (graduated over 5 years and with expertise in Oculoplastics, 77.2% ). As for the criterion of tumor aggressiveness, the results were closer among the different categories. Ophthalmologists trained longer and without expertise in Oculoplastics also showed a low diagnostic accuracy for malignancy and to determine the histological type of tumor. Conclusions: The low accuracy of clinical diagnosis of eyelid tumors in the groups above reinforces the need to improve ophthalmic oncology knowledge in these groups.
- Terapia fotodinâmica em carcinoma basocelular periocular: Relato de caso(2012) CARNEIRO, Rachel Camargo; MACEDO, Erick Marcet Santiago de; LIMA, Patricia Picciarelli de; MATAYOSHI, SuzanaThe authors report the use of photodynamic therapy with methyl aminolevulinate (Metvix (R)) in a patient with nodular and infiltrative basal cell carcinoma in the right lower eyelid. Side effects on the eye were evaluated weekly. After 12 weeks of treatment, to confirm cure the patient was submitted to a 2-mm punch biopsy, the anatomopathological findings of which were negative for neoplasia. Photodynamic therapy with methyl aminolevulinate was shown to be an attractive alternative to surgical excision(-)the current gold standard treatment worldwide.
- Tratamento cirúrgico da blefaroptose congênita(2014) MATAYOSHI, Suzana; PEREIRA, Ivana Cardoso; ROSSATO, Luiz AngeloA blefaroptose é o posicionamento inadequado da pálpebra superior, estando abaixo de sua posição normal na posição primária do olhar, a qual seria 0,5 – 2mm abaixo do limbo superior. Pode causar bloqueio parcial ou completo do campo visual superior, além do comprometimento estético. As causas são categorizadas em congênitas ou adquiridas. É considerada congênita se presente ao nascimento ou diagnosticada no primeiro ano de vida. As principais técnicas utilizadas para o tratamento da ptose congênita são a ressecção da aponeurose do músculo levantador da pálpebra superior (MLPS) e a suspensão frontal. A medida da função do MLPS é o parâmetro mais importante na escolha da técnica cirúrgica. Quando a função é fraca, a suspensão frontal é mais indicada; a ressecção supramáxima do MLPS também pode ser empregada. Acima de 4 ou 5mm de função do MLPS, prefere-se a ressecção da aponeurose. Para a cirurgia de suspensão frontal, vários são os materiais utilizados, portanto apresentamos uma comparação entre os estudos mais relevantes. Discutiremos também particularidades em casos mais complicados, como as Síndromes da Blefarofimose e de Marcus-Gunn, além de técnicas cirúrgicas menos utilizadas e as complicações relatadas.
- Tratamento de cistos conjuntivais em cavidade anoftálmica com injeção intralesional de ácido tricloroacético (ATA) a 25%(2013) FONSECA, Fabricio Lopes da; RAMOS, Renata de Iracema Pulcheri; MATAYOSHI, SuzanaConjunctival cysts in anophthalmic socket may have functional and aesthetic implications for the patients. Among the available treatment options, the use of trichloroacetic acid is relatively recent. Our reported cases showed a good outcome after 30 days of treatment, that was well tolerated by patients, with greater conjunctival tissue preservation.
