Brazilian Society of Angiology and Vascular Surgery 2023 guidelines on the diabetic foot.

The diabetic foot interacts with anatomical, vascular, and neurological factors that challenge clinical practice. This study aimed to compile the primary scientific evidence based on a review of the main guidelines, in addition to articles published on the Embase, Lilacs, and PubMed platforms. The European Society of Cardiology system was used to develop recommendation classes and levels of evidence. The themes were divided into six chapters (Chapter 1 - Prevention of foot ulcers in people with diabetes; Chapter 2 - Pressure relief from foot ulcers in people with diabetes; Chapter 3 -Classifications of diabetic foot ulcers; Chapter 4 - Foot and peripheral artery disease; Chapter 5 - Infection and the diabetic foot; Chapter 6 - Charcot's neuroarthropathy). This version of the Diabetic Foot Guidelines presents essential recommendations for the prevention, diagnosis, treatment, and follow-up of patients with diabetic foot, offering an objective guide for medical practice.

Thrombosis of the right iliac, femoral, popliteal, and tibial arteries in a post-COVID-19 in adolescent.

BACKGROUND: Viral infection into lung, muscular, and endothelial cells results in inflammatory response, including edema, degeneration, and necrotic alterations. The involvement of the major arteries in adolescent with COVID-19 has been infrequently reported in the literature. The aim of the present study is to report thrombosis of the right iliac, femoral and tibial arteries and stenosis of left iliac artery in an adolescent with COVID-19 and to discuss the pathophysiological hypotheses. CASE PRESENTATION: We report the case of a 17-year-old female patient with COVID-19 infection. She was seen at the physician specialized general medicine in her hometown, was diagnosed with COVID-19 but did not require hospitalization. After 15 days, she had sudden pain in the left leg that has limited her ability to walk more than 10 met, associated with extremity cyanosis and coldness. Angiotomography revealed thrombosis of a portion of the iliac and popliteal arteries. Na emergency embolectomy was successfully performed, followed by full-dose heparinization with unfractionated heparin. CONCLUSION: Arterial thrombosis of large arteries may be associated with chronic inflammatory syndrome secondary to COVID-19 infection and the treatment with a late embolectomy was successful, even in a thrombotic event.

Evaluation of postoperative complications in elderly patients submitted to parotidectomy. / Avaliação das complicações pós-operatórias em pacientes idosos submetidos à parotidectomia.

OBJECTIVE: to evaluate the most incident histological subtypes and the main postoperative complications in elderly patients with parotid tumors submitted to parotidectomy. METHODS: we conducted a retrospective study with 57 elderly patients submitted to parotidectomy from 2003 to 2017, at the São José County Hospital of Joinville, Santa Catarina, Brazil. RESULTS: thirty-three (57.9%) patients had benign tumors, the most frequent being Warthin's tumor, and 17 (29.8%), malignant tumors, squamous cell carcinoma being the most frequent. Seven patients (12.3%) presented clinical complications, arterial pressure instability and respiratory complications being the most frequent, in four (7%) and three (5.3%) cases, respectively. Thirteen (22.1%) patients presented complications related to the surgical wound, hematoma and wound infection being the most frequent, with six (10.5%) cases each. Twenty-four (42.1%) patients had some degree of facial nerve dysfunction in the postoperative period, Brackman-House grade III being the most frequent, in 11 cases (19.3%). Surgical time and lymphadenectomy were associated with clinical complications. The main variables that showed an association with surgical complications were tumor size, longer surgical time, reoperation, and perioperative crystalloid infusion volume. CONCLUSION: parotid neoplasms present a differentiated profile in the elderly population, especially Warthin's tumor and squamous cell carcinoma. Hematoma and infection of the operative wound and facial nerve lesions were the most prevalent complications in the postoperative period.

OBJETIVO: avaliar subtipos histológicos mais incidentes e as principais complicações pós-operatórias em pacientes idosos portadores de tumor de parótida e submetidos à parotidectomia. MÉTODOS: estudo retrospectivo de 57 pacientes idosos submetidos à parotidectomia, no período de 2003 a 2017, no Hospital Municipal São José de Joinville, Santa Catarina, Brasil. RESULTADOS: trinta e três (57,9%) pacientes tinham tumores benignos, sendo o mais frequente o tumor de Warthin, e 17(29,8%) tumores malignos, sendo o carcinoma escamoso o mais frequente. Sete (12,3%) pacientes evoluíram com complicações clínicas, sendo a labilidade pressórica e as complicações respiratórias as mais incidentes em quatro (7%) e três (5,3%) casos, respectivamente. Treze (22,1%) pacientes apresentaram complicações cirúrgicas relacionadas à ferida operatória, sendo o hematoma e a infecção de ferida as mais incidentes, com seis (10,5%) casos cada. Vinte e quatro (42,1%) pacientes tiveram algum grau de disfunção do nervo facial no pós-operatório, sendo o grau III de Brackman-House, em 11 casos (19,3%), o mais frequente. O tempo cirúrgico e a linfadenectomia mostraram associação com complicações clínicas. As principais variáveis que apresentaram associação com complicações cirúrgicas foram: tamanho do tumor, tempo cirúrgico mais longo, reoperação e volume de infusão de cristaloides no transoperatório. CONCLUSÃO: as neoplasias parotídeas apresentam perfil diferenciado na população idosa, destacando-se o tumor de Warthin e o carcinoma escamoso. Hematoma e infecção da ferida operatória, e as lesões do nervo facial foram as complicações mais prevalentes no pós-operatório.
