Purpose

We compared renal function outcomes among patients in the surveillance and intervention arms of the DISSRM registry.

The Role of Smoking in Breast Cancer Development: An Analysis of a Mayo Clinic Cohort

Abstract:  The purpose of this study was to assess the predictive value of smoking history on breast cancer diagnosis in a referral clinic population. We conducted a case–control study using clinical data collected on 8,097 female patients (1,225 breast cancer cases and 6,872 controls) seen in the Mayo Clinic Breast Clinic between August 1, 1993 and November 31, 2003. Breast cancer patients and noncancer patients significantly differed with respect to age at time of the index visit (p < 0.001), number of pregnancies (p = 0.006), number of live births (p = 0.002), vital status at last known follow-up (p < 0.001), current menstruation (p < 0.001), age at menopause (p < 0.001), history of hysterectomy (p < 0.001), use of oral contraception (p = 0.05), duration of oral contraception use (p = 0.001), use of other exogenous hormones (p < 0.001), duration of exogenous hormone use (p = 0.05), breast pain at time of index visit (p = 0.002), smoking status (p < 0.001), and use of five or more alcoholic beverages per week (p = 0.002). After adjustment for these baseline characteristics, having a personal history of smoking was found to be predictive of breast cancer diagnosis (odds ratios [OR] = 1.25, p = 0.004). Other positive predictors for breast cancer diagnosis were: age (OR = 1.02, p < 0.001), history of hysterectomy (OR = 0.66, p < 0.001), prior use of oral contraception for more than 11 years (OR = 2.10, p < 0.001), and prior use of other exogenous hormones/estrogen (OR = 1.81, p < 0.001). In this referral practice having a personal history of smoking is predictive of breast cancer diagnosis. Further studies are needed to further explore this relationship.     

Giant-cell tumour in the cervical spine: a case report

A forty-six-year-old man presented with a two-month history of increasing neck pain of insidious onset. He received treatment from his familty doctor and chiropractor consisting of analgesics and manipulation respectively, both of which did not offer relief. The patient presented to University Hospital where plain radiographs and CT showed a pathological fracture of the C4 vertebral body. A neoplasm was suspected and surgical excision revealed a giant-cell tumour of bone. This type of neoplasm is rare in the spine and difficult to manage in this site. This case highlights some of the problems encountered in the treatment of giant-cell tumour of the spine.     

以脉络膜转移为首发的胰尾粘液腺癌

目的:报告1例胰尾粘液腺癌表现为孤立性脉络膜转移瘤.方法:一位57岁女患者主诉右眼中心视物变形.检眼镜检查见1个位于右眼黄斑中心、长约6 PD的孤立性淡色隆起病灶.她没有特殊的既往眼科和全身病史.A/B超声检查证实在后极部黄斑内有一个实性病灶,荧光素血管造影发现中心病灶无渗漏区.结果:根据病史和临床发现,请求了FBC、血沉、LFT、胸部X线和腹部CT等检查.胸部X线发现在双肺野有多发性模糊的病灶,提示为转移性肺结节.CT发现肝内多发性结节和在胰尾的一个3.5 cm×2.6 cm病灶.进行了CT引导下的肝活检,证实为中度分化的转移性粘液腺癌.此后血液分析证实CA19-9升高.肿瘤原发部位证实为胰尾,并决定进行姑息治疗.结论:初发临床体征为孤立性脉络膜病灶经证实为胰尾癌的报告鲜见.这一病例提示,在发现未知来源实性脉络膜病灶的病例,进行详细的腹部影像学检查是重要的.     

分娩所致Valsalva视网膜病变治疗方法的探讨

目的:讨论孕妇Valsalva视网膜病变保守或手术治疗方法的选择.方法:一健康孕妇在自然阴道分娩时,右眼底发生黄斑前玻璃体后界膜下出血,本文报道其保守治疗的效果.结果:右眼发病3wk时积血收缩,视力为眼前手动,但病程6mo时,积血溶解,视力恢复至6/5.结论:大多数Valsalva视网膜病变能够自愈.对一些难治性病例,采用Nd:YAG激光行内界膜切开具有一定的效果.而早期玻璃体切除术的增殖膜切除,对预防眼底新生血管膜的发生也具有一定的效果.     

Nutritional status and serum zinc and selenium levels in Iranian HIV infected individuals

Background  

Human immunodeficiency virus infected individuals are prone to malnutrition due to increased energy requirements, enteropathy and increased catabolism. Trace elements such as zinc and selenium have major role in maintaining a healthy immune system. This study was designed to evaluate the nutritional status of Iranian subjects who were newly diagnosed with human immunodeficiency virus infection and to compare serum level of zinc and selenium in these patients with those of the sex and aged match healthy subjects.
