Quality of life after total mesorectal excision for rectal cancer

BACKGROUND: After total mesorectal excision for rectal cancer, many surgeons try to avoid an abdominoperineal resection (APR) by performing a transanally double stapled low colo-rectal anastomosis (LRA), frequently without a pouch. This policy is mainly based on the assumption that the quality of life after such LRA is higher than after APR. It has been suggested that a better functional outcome and therefore a higher quality of life might be achieved by a colo-anal J-pouch anastomosis (CPA). The aim of this study was to assess quality of life among disease-free survivors after APR, LRA and CPA. METHODS: The charts of 301 consecutive patients who had undergone surgery for cancer in the middle or lower third of the rectum were analysed. Two hundred four patients were eligible for inclusion. The quality of life among these patients was assessed using one generic (EQ-5D) and two disease-specific questionnaires (EORTC QLQ-C30 and EORTC QLQ-CR38). RESULTS: The response rate was 82%. The median follow-up was 31 months. Overall, quality of life was good but CPA patients had better quality of life scores than APR and LRA patients. This difference was not only due to the better functional outcome but also to the lower incidence of disturbed micturition and sexual problems in the CPA group. CONCLUSION: The quality of life after colo-anal J-pouch anastomosis is better than after abdominoperineal resection (APR) and low colo-rectal anastomosis (LRA). The quality of life after APR is similar to that after LRA.     

Procainamide therapy, physical performance and energy expenditure in the Schwartz-Jampel syndrome

The effects of procainamide administration were assessed in a 5-yr-old boy with Schwartz-Jampel syndrome (chondrodystrophic myotonia). Without procainamide the resting metabolic rate was found to be significantly higher than in an age-matched control group. With a serum level of 3.8 mg l-1 procainamide a reduction of the resting metabolic rate of 22% was observed, and times needed to climb stairs and to re-open eyes after forceful contraction (blepharospasm) were significantly reduced.     

Increased bone turnover during the third trimester of pregnancy and decreased bone mineral density after parturition in adolescents as compared to age-matched control patients.

To evaluate the impact of pregnancy on bone, we studied bone turnover at the first (T1) and third (T3) trimester of gestation in 58 adolescents and 28 healthy adolescents who had never been pregnant. Total body (TB) and lumbar spine (LS) bone mineral density (BMD) and body composition were evaluated by dual-energy X-ray absorptiometry in all control patients (C) and after parturition in 28 pregnant patients (G). Paired and unpaired t tests, Mann-Whitney and Pearson correlation tests were used. Bone turnover markers were above the reference range for adult women in more than 80% of the adolescents, with no difference between C and G patients at T1. Increase in urinary N-telopeptide crosslinks of type I collagen and serum bone-specific alkaline phosphatase, markers of bone turnover, was seen during pregnancy ( p < 0.0001). Body composition did not differ between groups, but LS BMD, percentage of expected LS BMD, LS Z-score, percentage of expected TB BMD and TB Z-score were lower in G than C patients ( p < 0.05). TB BMD was positively correlated with LS BMD (r2 = 0.52). The inverse correlations between bone markers and LS BMD suggest that the increased bone turnover during pregnancy probably explains the low bone density after parturition. The impact on future peak bone mass must be studied.     

What is the correct management of stage i UPSC?

UPSC has been identified as a distinct variant of endometrial cancer and it has been reported to be associated with more aggressive behavior and a worse prognosis compared to endometrioid adenocarcinomas of the endometrium. Various studies have demonstrated survival rates of 15–51% for clinical stage I disease and 35–90% for surgical stage I/II disease. Aside from the very limited number of studies that incorporate comprehensive surgical staging, the majority of these reports used clinical parameters for staging or very limited surgical staging techniques and information.
A significant amount of controversy surrounds the optimal management of patients with stage I UPSC, and appropriate management of these patients has yet to be firmly established. The low incidence of this particular type of cancer, the variety of surgical interventions, and the wide variety of post-operative adjuvant therapies have made it extremely difficult to identify the optimal management of patients with UPSC. Prior to 2004, adjuvant treatment recommendations for surgical stage I UPSC were largely based on very small retrospective patient series (<20 patients), only a fraction of which included surgically staged patients. A recent publication reported the outcomes of surgical stage I UPSC patients from four institutions ⁽¹⁾ . Recurrence rates were lower than that published in previous studies, suggesting a potential benefit of comprehensive surgical staging in these patients. The risk of recurrence and mean overall survival were similar between surgical stage I UPSC patients who were managed conservatively versus those treated with adjuvant radiation therapy. Moreover, this study also suggests a potential benefit of adjuvant chemotherapy in these patients.     

Anticerebellar antibodies--anti-Hu and anti-Yo--in the diagnosis of paraneoplastic neurologic syndromes]

The detection of antineuronal antibodies against cytoplasm and nuclei of Purkinje cells is considered to be an essential factor in the diagnosis of neurologic paraneoplastic syndromes. Published data rely on different immunological methods and relatively small numbers of patients. The clinical relevance of this phenomenon is not clear from the literature. A positive correlation between antibody detection and the appearance of neurologic paraneoplastic syndromes has been reported, but this finding has been questioned in critical reviews.     

Isolated complete orbital infarction: a common carotid artery occlusion syndrome

When blood flow through the internal and external carotid arteries is completely interrupted by ipsilateral common carotid artery occlusion, the arterial orbital circulation may be more compromised than the brain supply. We studied a pure and extreme example of this situation in a patient who presented with acute orbital infarction, but no cerebral ischemia on clinical, CT and single-photon emission computerized tomography (SPECT) grounds. Ipsilateral blindness corresponded to retinal, choroidal and optic nerve infarction. The pattern of ophthalmoplegia, with relative sparing of adduction, was more compatible with a muscle than a nerve dysfunction, but a reactive dilated pupil, corneal anesthesia, and orbital pain suggested that the intraorbital branches of the ocular motor nerves and ophthalmic division of the trigeminal nerve were not spared. In addition, signs of widespread ocular ischemia were present. Sequential examinations documented the evolution pattern over 1 year. The absence of an orbital collateral supply from the contralateral external carotid and muscular cervical arteries systems, which contrasted with an adequate middle cerebral artery supply via the contralateral internal carotid artery, may explain this isolated and complete form of orbital ischemia due to common carotid artery occlusion.
