RESUMO
INTRODUCTION: Cardiovascular disease is the main cause of mortality worldwide. In women, its incidence increases at the sixth decade of life, coinciding with postmenopause. Whether this effect is due to menopause-related hormonal changes is not known. OBJECTIVE: To evaluate the differences in cardiovascular risk in pre- and postmenopausal women by means of the Globorisk risk scale, the triglyceride/high-density lipoproteinsHDL cholesterol (Tg/HDL-C) ratio and metabolic syndrome (MS) criteria. METHOD: Cross-sectional study that included 408 women from 40 to 60 years of age; anthropometric measurements and biochemical determinations were performed. The participants were classified as premenopausal and postmenopausal. Cardiovascular risk was assessed using the MS criteria, the Globorisk risk calculator and the Tg/HDL-C ratio. RESULTS: Postmenopausal women showed a significant increase in waist circumference, total cholesterol and triglycerides Tg in comparison with premenopausal women. Significant associations were found between hormonal state and Globorisk-measured cardiovascular risk (OR = 2.50; 95 % CI = 1.67-3.74) and the Tgtriglyceride/HDL-C ratio (OR = 1.66; 95 % CI = 1.09-2.52). CONCLUSION: Cardiovascular risk factors have a higher prevalence in postmenopause. The Globorisk scale and Tg/HDL-C ratio identify cardiovascular risk in postmenopausal women.
INTRODUCCIÓN: La laringectomía subtotal supracricoidea asociada con cricohioidoepiglotopexia es la técnica quirúrgica conservadora más eficiente para preservar las funciones laríngeas de los pacientes con carcinoma localmente avanzado de la laringe. La complicación más temida de esta intervención es la aspiración en el momento de la deglución y la neumonía secundaria; existen diversas formas de evaluar la aspiración y el grado de esta. Presentamos una novedosa forma de identificar incluso pequeñas cantidades de aspiración traqueobronquial. MÉTODO: Se incluyeron pacientes sometidos a laringectomía subtotal y cricohioidoepiglotopexia por cáncer laríngeo; todos evaluados con trago radiactivo posoperatorio. Con base en la sintomatología y resultado del gammagramma se decidió prolongar el tiempo de alimentación por sonda. RESULTADOS: Se incluyeron 37 pacientes, cuatro habían recibido radioterapia; la tasa de aspiración fue de 29.7 %; 50 % de los pacientes que habían recibido radioterapia presentó aspiración y 18 % de los pacientes con aspiración requirió prolongación del tiempo de alimentación por sonda nasogástrica; ninguno necesitó laringectomía total por aspiración que no permitiera la deglución. CONCLUSIONES: La evaluación posoperatoria de pacientes sometidos a laringectomía subtotal con trago radiactivo permite identificar líquido aspirado al árbol bronquial, incluso en cantidades mínimas, y planear el momento para iniciar la deglución.

INTRODUCTION: Osteoradionecrosis of the mandible is a relatively common complication in patients with head and neck cancer undergoing radiotherapy or concomitant chemoradiotherapy, characterized by exposure of the mandibular bone either in the mouth or in the facial skin, with no improvement with conservative treatment for six months. The risk factors are radiotherapy in head and neck region, lack of dental prophylaxis before treatment and dental extraction. MATERIAL AND METHODS: Retrospective observational study analyzing incidence and etiologic factors of osteoradionecrosis in 250 patients undergoing radiotherapy or combined treatment of cervicofacial area between 2002 and 2010. RESULTS: 25 patients were included; the horizontal branch was the most affected area, followed by the anterior arch. Associated factors were: stage (T4a and T4b), tumor location (oral cavity), dental extraction pre or post-radiotherapy, and radiotherapy time (pre-or postoperative); 72% had association with tooth extraction. Only five patients had control with conservative measures, and 20 required some type of mandibulectomy, only three of them were candidates for reconstruction with fibular free flap; none received treatment in a hyperbaric chamber. CONCLUSIONS: The data suggest that osteoradionecrosis has a multifactorial origin, and prevention is the best alternative and includes pretreatment dental prophylaxis to avoid tooth extractions and close monitoring and surveillance in order to identify early osteoradionecrosis. Most patients require mandible resection as definitive treatment.

BACKGROUND: The standard of care for advanced-stage laryngeal cancer is combined treatment (chemo-radiotherapy). However, the complications with this treatment are not few, mainly in swallowing. Conservative laryngeal surgery remains an effective alternative for cancer control without the complications of chemo-radiotherapy. MATERIAL AND METHODS: Retrospective study was conducted on patients with laryngeal cancer cT3, cN0 with paraglottic infiltration, fixation of the vocal cord, minimal invasion of the hyo-thyroepiglottic space, but with normal arytenoid mobility and no sub-glottic extension, were treated with subtotal supracricoid laryngectomy. Complications, sequels of treatment, and local recurrence were evaluated. Bronchial aspiration was studied with radioactive swallow. RESULTS: There were 25 patients, 22 with negative surgical margins, one had tumour contact with the surgical margins, and 2 were positive. Two patients received postoperative radiotherapy. The mean decannulation was 15 days and removal of nasogastric tube 25 days. During the mean follow-up of 26 months, none of the patients had tumour recurrence or required conversion to total laryngectomy. In all patients swallowing has been normal and none required permanent or temporary tracheotomy or definitive gastrostomy. The voice is considered intelligible in all patients. Radioactive swallow showed aspiration in 15/25 patients, with none being clinically relevant. There were postoperative complications in 5 patients, and 4 patients required re-intervention but no conversion to total laryngectomy. CONCLUSION: Conservative surgery is an effective surgical-alternative to chemo-radiotherapy in patients with locally advanced laryngeal cancer, providing oncological control, acceptable complications and minimal sequels. Although most patients have aspiration, this does not affect functional status.

BACKGROUND: Skin tumours that originate in the external ear are common in individuals with type 1 skin and phenotype 1 and 2. The skin cancer is associated with chronic or intermittent, but intense sunlight. The most common malignant tumour is basal cell carcinoma, followed by squamous cell carcinoma and melanoma. The diagnosis of squamous cell skin cancer in head and neck area is usually made in the advanced stages and has a poor prognosis. MATERIAL AND METHODS: A cross-sectional, retrospective analysis was performed on the database of patients with skin cancer of the external ear treated between 2011 and 2014. Histology type, stage, rate of clinical and occult metastases, and rate of loco-regional recurrence were evaluated. RESULTS: Of the 42 patients included there were, 25 squamous cell carcinomas, 11 basal cell carcinomas, and 6 invasive melanomas. The rate of lymph node metastases in patients with squamous cell carcinoma was 32%, mostly in the parotid and peri-parotid region, 7% of them with capsular rupture, 2/17 were staged as cN0, and 11.7% had occult metastases. All patients with nodal metastasis were classified as T2 with ulceration. None of the patients with basal cell carcinoma had lymph node metastases. All melanomas were superficial extension type with mean level of Breslow of 3 mm. All underwent lymphatic mapping and sentinel node biopsy, with only one having metastases in the sentinel node. CONCLUSION: The most frequent tumour in the external ear in this series was squamous cell carcinoma. The possibility of lymph node metastases is associated with tumour size (T). Node dissection should be systematic in patients with T2 or greater.

BACKGROUND: The mortality of cutaneous melanoma has not declined over the past 50 years. The only interventions that can reduce mortality are primary prevention and early diagnosis, and the dermoscopic evaluation is essential to achieve this. Dermoscopy identifies characteristics of melanoma that would go unnoticed to the naked eye. The aim of this paper is to report the most frequent dermoscopic findings in patients diagnosed with in situ and invasive melanoma. MATERIAL AND METHODS: An observational and retrospective study of contact dermoscopy was performed using LED DermliteTM and camera DermliteTM dermoscope. The findings evaluated were: asymmetry in two axes, association of colours, lack of pigment, irregular points, atypical network, pseudopods, blue veil, ulceration, and peri-lesional pink ring. These dermoscopic findings were compared with the histological diagnosis. RESULTS: The study included 65 patients with cutaneous melanoma; 10 in situ, and 55 invasive. The mean Breslow in invasive melanoma was 3 mm. Most patients (35) had localization in extremities. In all patients, the most frequent dermoscopic finding was asymmetry in two axes, followed by association of two or more colours; in melanoma in situ, asymmetry was the most frequent, followed by atypical-irregular points. In invasive melanoma asymmetry in two axes, the association of two or more colours, and pseudopods, were the most frequent findings. CONCLUSION: Asymmetry in two axes is the most common dermoscopic finding in in situ and invasive melanoma. The presence of two or more colours in a pigmented lesion should be suspected in an invasive melanoma.

Objetivo: Reportar la experiencia en el manejo quirúrgico de pacientes con trombosis mesentérica venosa. Sede: Hospital de Tercer Nivel. Diseño: Estudio observacional, descriptivo, transversal, retrospectivo, Análisis estadístico: Porcentajes como medida de resumen para variables cualitativas. Pacientes y métodos: Estudio retrospectivo en el que se incluyeron 8 pacientes intervenidos quirúrgicamente durante un periodo de 5 años. Cinco de los pacientes tenían antecedentes o factores asociados a trombosis. El síntoma más común en la mayoría fue dolor abdominal de más de tres días de evolución. En todos, la trombosis mesentérica venosa se clasificó como secundaria y fue necesario realizar resección intestinal del segmento afectado. Seis pacientes tuvieron buena evolución y permanecieron con manejo anticoagulante. Dos pacientes fallecieron por complicaciones embólicas pulmonares. Conclusiones: La trombosis mesentérica venosa es una entidad rara con sintomatología vaga. Antecedentes del paciente, sospecha diagnóstica y estudios de imagen son los factores más importantes para realizar el diagnóstico al que es infrecuente llegar antes de la operación. La cirugía con resección del segmento afectado conlleva a resultados aceptables.
Objective: To report our experience with patients with mesenteric vein thrombosis managed surgically. Setting: Third level health care hospital. Design: Observational, descriptive, retrospective study. Statistical analysis: Percentages as summary measure for qualitative variables. Patients and methods: During a 5-year period, eight patients with mesenteric vein thrombosis were managed surgically; five of them had known risk factors for the development of venous thrombosis or had previous events of thrombosis at other sites. Abdominal pain was the predominant symptom, in most cases of three or more days. All had secondary vein thrombosis and required resection of the affected bowel. Six of them survived and were kept on anticoagulation therapy. Two patients died due to pulmonary embolism. Conclusions: Mesenteric vein thrombosis is a rare entity with vague symptoms. Medical history of the patient, clinical suspicion, and radiological studies are the most important factors for diagnosis; this latter is rarely attained preoperatively. Surgical management with resection of affected bowel leads to acceptable outcomes.
