Axial Axis Metastasis / Metástase do eixo axial

Abstract Axial axis metastasis remains a challenge for surgical as well as other treatment modalities, like chemotherapy, immunotherapy, and radiotherapy. It is unequivocal that surgery provides pain improvements and preservation of neurological status, but this condition remains when associated with radiotherapy and other treatment modalities. In this review, we emphasize the current forms of surgical treatment in the different regions of the spine and pelvis. The evident possibility of percutaneous treatments is related to early or late cases, and in cases in which there are greater risks and instability to conventional surgeries associated with radiotherapy and have been shown to be the appropriate option for local control of metastatic disease.

Resumo As metástases no eixo axial permanecem um desafio para o tratamento cirúrgico bem como para outras modalidades, como quimioterapia, imunoterapia e radioterapia. É inequívoco que a cirurgia proporciona melhorias na dor e na preservação do status neurológico; porém, há permanência desta condição quando associada à radioterapia e a outras modalidades de tratamento. Nesta revisão damos ênfase às formas de tratamento cirúrgico atuais nas diferentes regiões da coluna vertebral e pelve. A evidente possibilidade de tratamentos percutâneos está relacionada a casos iniciais ou tardios, bem como a casos em que há maiores riscos e instabilidade às cirurgias convencionais associadas à radioterapia, e tem se mostrado a opção adequada para o controle local da doença metastática.

Spontaneous fracture of an implanted posterior chamber polyimide intraocular lens haptic: A case report.

A 57-year-old male patient visited our clinic for decreased visual acuity in the right eye for 10 days. He denied any trauma history, but recalled that the symptom developed after straining. He had undergone uncomplicated phacoemulsification and posterior chamber intraocular lens (IOL) implantation in the bag of the right eye 11 years ago. The IOL was a three-piece silicone polyimide-haptics design. On slit-lamp examination, the IOL optic and proximal part of nasal fractured haptic were found in the anterior chamber. The distal part of fractured haptic was observed in the capsular bag. He underwent IOL exchange. The fracture site of the haptic was near the optic–haptic junction. This is the unique case report of a spontaneous fracture of an implanted posterior chamber polyimide IOL haptic, which implies the possibility of IOL haptic fracture in various haptic materials.

@#BACKGROUND: We commonly encounter fractures secondary to trauma on and off in our daily practice. While it is not uncommon to see fractures due to underlying pathology, we need to be on the alert when patients present atypically because the treatment for pathological fractures is far different from that for simple fractures. METHODS: We presented a case of left clavicle fracture secondary to minor trauma, in which the initial X-ray shows suspicious lesion around the fracture site and further investigation reveals multiple myeloma. The patient received treatment at the clinical oncology department upon diagnosis. Since he was relatively young and fit, he was started on the induction therapy of VTD, which was followed by high dose melphalan and autologous stem cell transplant. RESULTS: He is currently free from symptoms and on maintenance thalidomide. CONCLUSIONS: Though multiple myeloma is not commonly encountered in emergency practice, earlier identification of relatively subtle symptoms can allow early treatment. Missing this diagnosis will delay treatment and produce severe outcome to the patient. We should be on the alert for such important condition.

Spontaneous Fracture of a Lumboperitoneal Shunt Catheter: A Case Report

Spontaneous fracture of the Silastic shunt catheter is a rare complication of lumboperitoneal shunt. A review of the literature revealed only one case in which spontaneous fracture occurred after this procedure. The authors report a case in which fracture of a lumboperitoneal shunt catheter occurred within the interspinous ligament probably due to repeated tension caused by flexion and extension during lumbar motion. The fractured proximal catheter was located entirely within the intrathecal space exclusively from the level of L1 to S1, and caused incomplete cauda equina syndrome.
