Fatores de risco para trauma vascular durante a quimioterapia antineoplásica: contribuições do emprego do risco relativo

OBJETIVO: identificar a relação entre os fatores de risco para trauma vascular e o surgimento de eventos adversos de infiltração ou flebite por quimioterapia antineoplásica. MÉTODOS: Estudo de abordagem quantitativa observacional com 30 mulheres com câncer de mama. RESULTADOS: O tipo de material do cateter apresentou associação que sugere risco (RR=2,76; IC=1,199; 6,369); o fator velocidade de infusão apresentou RR=2,22; entretanto, IC= 0,7672; 6,436; os fatores trajetória, número de punção e mobilidade da veia apresentaram RR<1 mas não podem ser considerados como fatores de proteção. Local de inserção e a visibilidade da veia apresentaram risco próximo a 1. CONCLUSÃO: O uso de cateter com metal para punção venosa foi considerado neste estudo como fator para Risco de Trauma Vascular. A análise da associação pelo RR mostrou-se concordante com os dados da literatura pesquisada.

Periocular basal cell carcinoma: cost of topical immunotherapy versus estimated cost of surgical treatment

Purpose: 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.

Oral health as a predictive factor for oral mucositis

OBJECTIVES: Oral mucositis is a complication frequently associated with hematopoietic stem cell transplantation, decreasing a patient’s quality of life and increasing the occurrence of opportunistic infections. The purpose of this study was to determine the incidence and severity of oral mucositis and to assess the correlation of this disease with the oral health of an individual at the time of hematopoietic stem cell transplantation. METHODS: Before transplantation, patients’ oral health and inflammatory conditions were determined using the gingival index and the plaque index, which are based on gingival bleeding and the presence of dental plaque, respectively. Additionally, the dental health status was determined using the decayed, missing, and filled teeth index. The monitoring of oral mucositis was based on the World Health Organization grading system and was performed for five periods: from Day 0 to D+5, from D+6 to D+10, from D+11 to D+15, from D+16 to D+20, and from D+21 to D+30. RESULTS: A total of 97 patients (56% male and 44% female) who underwent hematopoietic stem cell transplantation at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo between January 2008 and July 2009 were prospectively examined. The incidence of ulcerative mucositis was highest from days +6 to +10 and from days +11 to +15 in the patients who underwent autologous and allogeneic hematopoietic stem cell transplantation, respectively. CONCLUSION: The data, including the dental plaque and periodontal status data, showed that these oral health factors were predictive of the incidence and severity of oral mucositis in a cohort of patients with similar conditioning regimens before hematopoietic stem cell transplantation

A avaliação da rede venosa pela enfermagem em mulheres com câncer ginecológico durante o tratamento quimioterápico

Estudo de abordagem exploratória e descritiva que teve como objetivos: avaliar a rede venosa das mulheres com câncer cérvico uterino, no início e ao final do tratamento quimioterápico; analisar a ocorrência de flebite provocada pelas drogas utilizadas nos protocolos de quimioterapia neoadjuvante e adjuvante e relacionar os tipos de veia com os dispositivos mais utilizados, tempo de permanência e intercorrências. Utilizou-se um instrumento de avaliação da rede venosa para os membros superiores. Foram incluídas 20 mulheres atendidas em um hospital de ensino do interior do Estado de São Paulo. A avaliação da rede venosa demonstrou poucas alterações, e a intercorrência mais frequente foi o hematoma (60%). Os resultados deste estudo apontam para aspectos da prática de enfermagem relacionados à administração de quimioterápicos e ressaltam a necessidade de elaborar e implantar protocolos para o cuidado.

Multiple trichoblastomas in a dog

Background – Hair follicle tumours generally present as benign, solitary masses and have a good prognosis following surgical resection. Hypothesis/Objectives – This report describes a case of multiple trichoblastomas in a dog. Animal – A 2-year-old crossbred dog presented with multiple soft cutaneous periocular, perilabial, submandibular and nasal nodules, between 2 and 9 cm in diameter, located on the right side of the face. New nodules were observed on the same side of the face at a second consultation 3 weeks later. Methods – Surgical resection of all nodules was performed in two procedures. Three nodules were initially resected and submitted for histolopathology and immunohistochemistry. The diagnosis was trichoblastoma for all three. At the time of the second consultation, new and remaining nodules were biopsied and the diagnosis of trichoblastoma confirmed. The dog was treated with doxorubicin and piroxicam for 30 days prior to the second surgical procedure in an attempt to reduce new tumour growth and the size of present tumours. All nodules were resected and the defects closed using rotation flaps. Results – No recurrence of the neoplasm was noted within 10 months after surgery. Conclusions and clinical importance – Trichoblastomas are generally benign but can present as multiple neoplasms that may require surgical resection and may respond to chemotherapy. To the authors’ knowledge, this is the first report of multiple trichoblastomas in a dog.
