PET-CT scanning has been proposed as part of the pre-treatment evaluation of GI cancers with equivocal radiologic findings. PET-CT has also been prosposed for the evaluation of patients with chronic inflammatory bowel disease (IBD). We report the case of a patient with IBD and a new diagnosis of rectal cancer; PET-CT overestimated the degree of tumor extension due to false-positive increased uptake in areas of chronic inflammation from IBD. This observation underlines the need for cautious interpretation of PET-CT results for cancer in patients with associated inflammatory illness.  相似文献

Background

The authors studied a cohort of 154 patients with unilateral vocal cord paresis following thyroidectomy, analyzing the pathogenesis, symptomatology, spontaneous evolution, and management of this complication.

Objective

This retrospective study distinguished between vocal cord paresis due to recurrent laryngeal nerve injury or due to injury of the cricoarytenoid articulation. We assessed the influence multiple variables on therapeutic management. The results and complications of currently-employed surgical techniques to remedy unilateral vocal cord paresis were defined.

Patients and methods

Injury to the recurrent laryngeal nerve was the cause of vocal cord paresis in 98% of cases; injury to the cricoarytenoid articulation accounted for only 2% of cases. When the recurrent laryngeal nerve had not been actually transected, spontaneous recovery of vocal cord function occurred in 36% of cases. No spontaneous recovery was noted when the nerve had been divided. The interval to recovery of cord function ranged from 2 to 15 months (median: 4 months). Spontaneous recovery of vocal cord function had occurred in 90% of these patients by the 9th postoperative month. Three factors significantly influenced the decision to perform a median transposition of the injured vocal cord: known transection of the recurrent laryngeal nerve, the interval to consultation with an ENT specialist, and the severity of dysphonia. Medial transposition of the injured vocal cord resulted in an immediate improvement in the quality of voice and speech with no major complications.

Conclusion

Unilateral vocal cord paresis occurring after thyroidectomy is not always symptomatic and is not uniformly due to injury of the recurrent laryngeal nerve. Management does not always require surgical reintervention. The practical and medico-legal consequences of these injuries are discussed.  相似文献

Hip femur is extremely common in the elderly and is one of the most common reasons for admission in trauma care. The main reported causes of death after hip fracture were cardiovascular (29%), neurological (20%) and pulmonary. Large epidemiological studies have shown a relatively small decrease in mortality for 20 years despite an active approach to medical and surgical management. Yet 57% of deaths occurring within 30 days post-surgery are preventable because they are not related to a pre-existing disease. Preoperative management to optimize these patients could help to reduce morbidity and mortality and is thus a crucial issue. The anesthesia consultation is used to evaluate the perioperative risk, treat pain, manage treatment and stabilize the patient. An operative delay of more than 48 hours after admission increases mortality. This period should not be prolonged by unnecessary investigations that will not change the perioperative management. The preoperative period is a key moment because it allows to choose the anesthetic technique. Even if this choice is controversial, continuous spinal anesthesia (titrated) do not modify the cardiovascular and neurological physiological balance of these precarious patients.  相似文献
