ABSTRACT
Objective The purpose of the present study is to demonstrate the usefulness of intraoperative ultrasound guidance as a technique for the assessment, in real time, of tumor resection and as a navigation aid during intra-axial brain lesion removal on patients admitted in the Neurosurgical Department at the Hospital Universitario de Caracas, Caracas, Venezuela, in 2018. Methods A total of 10 patients were enrolled, each with intra-axial brain lesions with no previous neurosurgical procedures and a mean age of 49 years old, ranging from 29 to 59 years old. Results A male predominance was observed with 7 cases (70%) over 3 female cases (30%). Six patients had lesions in the dominant hemisphere. The frontal lobe was the most commonly affected,with 5 cases, followed by the parietal lobe,with 4 cases. After craniotomy, ultrasound evaluation was performed previously to dural opening, during tumor resection and after tumor removal. The mean tumor size in axial, coronal and sagittal views was 3.72 cm, 3.08 cm and 3.00 cm, respectively, previously to dural opening with intraoperative ultrasound. The average tumor depth was 1.73 cm from the cerebral cortex. The location and removal duration from the beginning of the approach (ultrasound usage time) was 83.60 minutes, and the average surgery duration was 201 minutes. Navigation with intraoperative ultrasound served to resect intra-axial tumors more precisely and safely. There was no postoperative complication associated with the surgery in this series of cases. Conclusions Intraoperative ultrasound guidance for intra-axial subcortical tumor resection is a technique that serves as a surgical and anatomical orientation tool.

RESUMEN La espondilitis tuberculosa (enfermedad de Pott) representa del 1-5% de los casos de tuberculosis. Se presenta un caso clínico de una paciente femenina de 14 años de edad con esta patología complicada con fractura de cuerpos vertebrales T4, T7, T8 y T9; a quien se le realizó un abordaje por vía posterior, consistente en laminectomía completa bilateral de T3, T4, T7, T8, T9 preservando las articulaciones facetarias, mas artrodesis instrumentada con ganchos sublaminares en T1-T2, colocación de alambres sublaminares T5 y T6, tornillos transpediculares en T11 y dos barras de titanio. Con excelentes resultados postoperatorios. Además, se discuten las diferentes vías de abordaje quirúrgico de esta patología.
ABSTRACT Tuberculous spondylitis (Pott's disease) represent 1-5% of tuberculosis cases. We present a clinical case of a female patient of 14 years of age with tuberculous spondylitis (Pott's disease) complicated with vertebral body fracture T4, T7, T8 and T9, who underwent a posterior approach, bilateral complete laminectomy of T3, T4, T7, T8, T9 preserving the facet joints, more arthrodesis instrumented with sublaminar hooks in T1-T2 placement of sublaminar wires T5 and T6 placement of transpedicular screws in T11, and two titanium bars. With excellent postoperative results. In addition, the different surgical approaches to this pathology are discussed.

Objetivo: Determinar el riesgo de Diabetes Mellitus tipo 2, en la comunidad rural de Apostadero, Municipio Sotillo. Estado Monagas. Venezuela. Materiales y métodos: Se realizó un estudio observacional, descriptivo y de corte transversal en Enero de 2013. Universo conformado por 163 personas mayores de 18 años. Se tomaron medidas antropométricas (peso, talla, índice de masa corporal [IMC], y circunferencia abdominal), glicemia capilar, tensión arterial y se aplicó la encuesta FINDRISC para estimar riesgo de diabetes en 10 años. Resultados: De una muestra de 41 voluntarios, 25 (61%) eran de género femenino y 16 (39%) de masculino. El promedio de IMC fue 28,08±5,69, la prevalencia de sobrepeso fue de 24,4% y de obesidad de 36,6%. El género femenino fue más afectado con IMC promedio de 29,52±6,04 vs masculino 25,84±4,37 (p<0,05). La prevalencia de pre-hipertensión fue de 31,7% y la de hipertensión arterial fue de 53,7%. La glicemia capilar media fue de 93,63±12,18 mg/dL y en cuanto al género no hubo diferencias significativas (p=0,17), la prevalencia de alteración de glicemia en ayunas fue de 24,4% y de Diabetes mellitus tipo 2 de 4,9%. El 21,95% de los encuestados estaban en alto riesgo de desarrollar diabetes mellitus tipo 2, siendo las mujeres las más afectadas significativamente (p=0,047). Conclusión: La población tiene un elevado riesgo de desarrollar diabetes tipo 2 en 10 años, siendo las féminas las más vulnerables.
Objective: To determine the risk of type 2 diabetes in the rural community of Apostadero, Sotillo Municipality. Monagas State. Venezuela. Methods: An observational, descriptive, cross-sectional study in January 2013 was performed. The universe was composed of 163 people over 18 years. Anthropometric measurements (weight, height, body mass index [BMI] and waist circumference), capillary glucose and blood pressure were taken. The FINDRISC survey was used to estimate the risk of diabetes in 10 years. Results: From a sample of 41 volunteers, 25 (61%) were female and 16 (39%) male. The mean BMI was 28.08 ± 5.69, the prevalence of overweight was 24.4% and obesity was 36.6%. Female gender was more affected with an average BMI of 29.52 ± 6.04 vs 25.84 ± 4.37 in men (p <0.05). The prevalence of prehypertension was 31.7% and that of hypertension was 53.7%. The mean capillary blood glucose level was 93.63 ± 12.18 mg/dL without gender differences; the prevalence of impaired fasting glucose was 24.4% and type 2 diabetes mellitus of 4.9%. High risk of developing type 2 diabetes mellitus was observed in 21.95% of the participants, women being the most affected (p=0.047). Conclusion: The population has a high risk of developing type 2 diabetes within 10 years, being women the most vulnerable.
