Manejo del dolor óseo en pacientes cancerosos / Bony pain management in cancerous patients

Las metástasis óseas se desarrollan en aproximadamente 30 a 70% de todos los pacientes con cáncer. El dolor es una experiencia de la condición humana universal, y es común que las personas busquen atención médica a raíz de ello. El presente estudio tuvo como objetivo describir la eficacia y el papel de diferentes estrategias en el control del dolor óseo en pacientes cancerosos metastásicos. Se trata de un estudio observacional realizado entre el 1 de diciembre de 2018 y el 30 de diciembre de 2019. Se inscribieron exactamente 100 pacientes cancerosos. Los pacientes fueron evaluados antes de recibir las modalidades de control del dolor, al principio y al final del tratamiento. La puntuación del dolor óseo se utilizó de 0 (sin dolor) a 10 (el peor dolor). Nuestros hallazgos con respecto al sexo, hubo 51 (51%) hombres y 49 (49%) mujeres. La edad media fue de 57,3 ± 11,2 años y el grupo de edad más frecuente fue de 41-50 años, 37 (37%). Entre los tipos de cáncer, el cáncer de mama ocupa el primer lugar entre los casos estudiados en nuestra investigación 37 (37%), seguido del cáncer de próstata 24 (24%). Las vértebras de la columna fueron el sitio más representado en un 52%, seguido de los huesos pélvicos en un 36%. La mayoría de los pacientes no requirieron cirugía.

El dolor agudo se describió comúnmente en un 40%, seguido de naturaleza punzante en un 15%. El dolor frecuente fue más prevalente en el 60% de los pacientes, mientras que el dolor constante se presentó en el 40%. La noche fue el momento más común de sentir dolor en el 55%. Después de recibir el tratamiento, varias modalidades provocan un desplazamiento de la puntuación del dolor hacia abajo. Combinación de más de estrategias más eficientes que utilizar una opción para el manejo del dolor óseo con un mejor resultado y pronóstico.

Bone metastases develop in approximately 30­70% of all cancer patients. Pain is a universal human experience condition, and it is a common question for people to seek health care. The study aimed to describe the efficacy and roles of different strategies in the control of bony pain in metastatic cancerous patients. This is an observational study carried out, from the 1st of December 2018 to the 30th of December 2019. Exactly 100 cancerous patients were enrolled. Patients were assessed before received of pain control modalities, in the beginning, and at the end of treatment. Bone pain scoring was used from 0 (no pain) to 10 (the worst pain). Our findings regarding sex, there were 51(51%) male and 49(49%) female. The mean age was 57.3±11.2 years, and the most frequent age group was 41-50 years as 37(37%). Among cancer types, breast cancer comes in 1st rank cases studied in our research 37(37%), followed by prostate cancer 24(24%). Spine vertebrae were the most site figured 52%, followed by pelvic bones in 36%. Most patients did not require surgery. Whereas 15% of patients underwent cord decompression, 13% required internal fixation and only four patients performed for vertebroplasty. The sharp pain was commonly described by 40%, followed by stabbing nature in 15%. Frequent pain was more prevalent in 60% of patients, whereas constant pain presented in 40%. The night was the commonest timing of feeling pain in 55%. After receiving treatment, several modalities cause shifting of the pain scoring downward. Combination of more than strategies more efficient than of use one option for manage of bone pain with a better outcome, and prognosis.

Cervical Vertebral Metastasis from Tongue Carcinoma: A Rare Case Report and Review.

Head and neck cancers are emerging as major health problems in India. In 2010, head and neck cancer was ranked as the sixth leading cause of cancer death worldwide. Approximately 481,100 new cases developed, and 320,000 persons died of this disease, resulting in an average mortality rate of 7.3 and 3.2 per 100,000 males and females, respectively. Oral squamous cell carcinoma is the most common head and neck malignancy having a propensity for the locoregional spread. Vascular invasion is very rare when compared to lymphatic spread. Most frequent sites of distant metastasis are lung, bone, liver, adrenals, heart, and kidney. We report a rare case of 39-year-old male with cervical vertebral metastasis from tongue carcinoma which is 9th case reported according to literature.

MINIMALLY INVASIVE PASSAGE IN POSTERIOR LAMINOTOMY DECOMPRESSION AND INTERVERTEBRAL BONE GRAFTING COMBINED WITH PERCUTANEOUS PEDICLE SCREW FIXATION FOR TREATMENT OF Denis TYPE B THORACOLUMBAR BURST FRACTURES / 中国修复重建外科杂志

RESULTS: The operation was successfully completed in all patients; the average operation time was 150 minutes (range, 90-240 minutes); the average bleeding volume was 350 mL (range, 50-500 mL); the average postoperative drainage was 80 mL (range, 20-150 mL); and the average VAS score was 2.3 (range, 1.5-4.7) at 3 days after operation. The incisions healed primarily. All the patients were followed up 12-19 months (mean, 15 months). All fractures healed at 3-9 months (mean, 6 months). No complications of broken nails, broken rod, and screw loosening occurred. At last follow-up, the vertebral canal patency rate was significantly improved when compared with preoperative value (t=27.395, P=0.000). The Cobb angle, and the anterior and posterior heights of of traumatic vertebra were significantly improved at 1 week, 1 year, and last follow-up when compared with preoperative ones (P0.05). The neurological function was improved in different degrees; 1 case was rated as grade A, 4 cases as grade B, 7 cases as grade C, 15 cases as grade D, and 26 cases as grade E, showing significant difference when compared with preoperative one (Z=-5.477, P=0.000).

Effects of Microscopic Anterior Cervical Approach in Cervical Spondylotic Diseases / 天津医药

Objective To assess the curative effect of microscopic anterior cervical approach in cervical spondylotic diseases. Methods A total of 75 patients were selected, who underwent microscopic subtotal anterior cervical decompres-sion and titanium mesh to fusion fixation or microscopic decompression of resection of the cervical intervertebral disc and cage implant fixation in Tianjin People's Hospital since October 2011 to October 2012. The Cervical vertebra gap involved 1 level in 41 cases, 2 levels in 30 cases and 3 levels in 4 cases. Pateints followed up regularly after operation. The nerve func-tion was assessed using Japanese orthopaedic association scoring system (JOA) function was calculated to examine the im-provement rate and to assess the curative effect of microscopic anterior cervical approach. Results All patients were fol-lowed up. The nerve function recovery was excellent in 44 cases, was well in 25 cases, was general in 6 cases, and the ex-cellent and well recovery rate was 92%. There was no significant difference between excellent recovery rate and well recov-ery rate. There were significant differences in values of each cervical levels between before and after surgery in the last fol-low-up of patients (P<0.05). Conclusion Microscopic operative treatment for cervical spondylotic is safe and effective, with less trauma and bleeding. After surgical decompression, the recovery is rapid in patients with early ambulation.

Acondroplasia -estenosis del canal medular- una complicación neurológica / Achondroplasia -spinal canal stenosis-a neurological complication

Introducción. La acondroplasia es un trastorno genético del crecimiento óseo de herencia autosómica dominante. Su incidencia es de 1:26,000 nacimientos por año. Este trastorno es causado por una mutación en el gen que codifica al receptor tipo 3 del factor de crecimiento del fibroblasto (FGFR3) en el cromosoma 4, el cual se expresa en los condrocitos de la placa de crecimiento de los huesos; de esta manera afecta la osificación endocondral. Se manifiesta clínicamente por talla baja con desproporción anatómica, macrocefalia, acortamiento de extremidades y deformidades esqueléticas. Las complicaciones neurológicas de la acondroplasia son la causa más frecuente de morbilidad y mortalidad. Caso clínico. Se trata de un paciente femenino de 5 años de edad con acondroplasia que ingresó con diagnóstico de enfermedad tipo influenza. A la exploración física presentaba clonus, hiperreflexia, limitación funcional de extremidades y retraso del desarrollo psicomotor. Durante su estancia intrahospitalaria presentó paro respiratorio que ameritó fase III de ventilación; por la debilidad de los músculos torácicos no fue posible la extubación. Se realizó una tomografía de cráneo y una imagen de resonancia magnética cráneo-cervical, encontrando la compresión del canal cérvico-medular. Conclusiones. La identificación temprana de la compresión medular y su descompresión inmediata pueden ayudar a prevenir complicaciones serias, como la insuficiencia respiratoria y la muerte súbita.

Background. Achondroplasia (AC) is an autosomal dominant genetic disorder of bone growth with an annual incidence of 1:26,000 births. It is caused by a mutation in the gene encoding the receptor type 3 growth of fibroblast factor (FGFR3) on chromosome 4, which is present in chondrocytes of the growth plate of bones, thus affecting endochondral ossification. It is manifested clinically by short stature with anatomic disproportion, macrocephaly, shortened limbs and skeletal deformities. Neurological complications of AC are the most common cause of morbidity and mortality. Case report. We report the case of a 5-year-old female patient with achondroplasia who was admitted with a diagnosis of influenza-like illness. Physical examination revealed clonus, hyperreflexia, limb functional limitation, and delayed psychomotor development. During her hospital stay the patient experienced respiratory arrest, necessitating the use of phase III mechanical ventilation, making extubation impossible due to weakness of chest muscles. Cranial computed tomography (CT) and cervical magnetic resonance imaging (MRI) were performed, demonstrating compression of the cervicospinal canal. Conclusions. Early identification of spinal cord compression and its immediate decompression can help to prevent serious complications, including respiratory failure and sudden death.

Operative Treatment of Cervical Spondylotic Myelopathy by Bilateral Backward Displacement of Lamina and Expansion of Nerve Root Canal / 中华骨科杂志

Objective:To evaluate the results of 25 cases of cervical spondylotic myelopathy treated by the bilateral backward displacement of lamina and expansion of the nerve root canalsince 1994. Method: Thepostopera tire and preoperative CT and MR imaging were used to compare the efficacy of backward displacement and decompression of the spinal cord. Result: According to the criteria for assessment set up by Dr Yin Huafu, the result was excellent in 13 cases, good in 8 and acceptable in 3; one case failed to get any improvement. Conclusion: This operation is a safe and an effective procedure for the treatment of the majority cases of cervical spondylotic myelopathy. In some cases this procedure should be done in combination with anterolateral decompression.
