The primary health care physician and the cancer patient: tips and strategies for managing sexual health

There is a large and growing population of long-term cancer survivors. Primary care physicians (PCPs) are playing an increasingly greater role in the care of these patients across the continuum of cancer survivorship. In this role, PCPs are faced with the responsibility of managing a range of medical and psychosocial late effects of cancer treatment. In particular, the sexual side effects of treatment which are common and have significant impact on quality of life for the cancer survivor, often go unaddressed. This is an area of clinical care and research that has received increasing attention, highlighted by the presentation of this special issue on Cancer and Sexual Health. The aims of this review are 3-fold. First, we seek to overview common presentations of sexual dysfunction related to major cancer diagnoses in order to give the PCP a sense of the medical issues that the survivor may present with. Barriers to communication about sexual health issues between patient/PCPs in order are also described in order to emphasize the importance of PCPs initiating this important conversation. Next, we provide strategies and resources to help guide the PCP in the management of sexual dysfunction in cancer survivors. Finally, we discuss case examples of survivorship sexual health issues and highlight the role that a PCP can play in each of these case examples.     

原发性肝癌患者手术切除术后早期复发影响因素分析

目的:探究原发性肝癌患者手术切除术后早期复发影响因素分析。方法:对广州市番禺区中医院2017年2月-2019年2月收治的原发性肝癌患者98例进行回顾性分析,依据各项临床指标分析手术切除术后早期复发的影响因素。结果:原发性肝癌患者经由手术切除后出现复发的可能性较高,同时手术切缘有残留、包膜不完整、肿瘤结节、心理因素、甲胎蛋白、血管侵犯、肝硬化及肿瘤直径等均是影响原发性肝癌手术期后再复发的高危因素。结论:原发性肝癌通常具有术后复发的生物学特性,依据对手术切除术之后早期复发因素的分析,对手术风险与治疗方案进行充分评估,同时要求患者进行定期复查及随访等工作,可对患者手术成功以及并发症的防治等均具有积极意义。     

Expression of the β‐adhesin part of HRgpA in Sprague Dawley rats induces a specific antibody response

The β‐adhesin part of the Porphyromonas gingivalis W50 (ATCC 53978) protease HRgpA was cloned in an eukaryotic expression vector and expressed in COS‐7 cells. The monoclonal antibody MAb (61BG1.3), specific for the hemagglutinating domain of β‐adhesin, recognized the expressed β‐adhesin in the transfected cells both by immunoblot and immunofluorescence. Sprague Dawley rats were immunized intramuscularly with β‐adhesin encoding expression plasmid and expression plasmid without β‐adhesin insert. Skeletal muscle tissue at the site of immunization in the β‐adhesin immunized animals was shown to express this protein. The immunization induced a β‐adhesin‐specific antibody response. Sera from the immunized animals were tested for hemagglutination inhibiting activity. Due to high natural inhibiting activity in all rat sera tested, no increased hemagglutination inhibition was detected in sera from the β‐adhesin immunized animals.     

尼莫地平联合卡维地洛治疗原发性高血压78例临床分析

目的分析尼莫地平联合卡维地洛治疗原发性高血压的临床疗效。方法将150例原发性高血压随机分成两组,对照组给予尼莫地平治疗,治疗组在对照组治疗的基础上,加之卡维地洛。结果治疗组与对照组显效率分别为33.3%和26.4%,总有效率为88.5%和76.4%,两组相比具有显著性差异（P〈0.05）。结论尼莫地平联合卡维地洛治疗原发性高血压疗效更为显著。     

干燥综合征与病毒感染的关系研究进展

干燥综合征是一种以口眼干燥为特征,主要累及外分泌腺的弥漫性结缔组织病。其发病可能与病毒感染、遗传和性激素异常等多种因素有关,在这些因素的共同作用下,机体免疫异常,组织损伤。与该病关系较密切的病毒有EB病毒、丙型肝炎病毒、巨细胞病毒、反转录病毒等。病毒在干燥综合征的发病机制中可能起重要的作用。     

血清α—L-岩藻糖苷酶（AFU）对原发性肝癌（PHC）的诊断意义

目的研究血清α-L-岩藻糖苷酶（AFU）对原发性肝癌的诊断意义。方法分别测定20例正常对照者、45例慢性乙型肝炎、40例肝硬化、50例转移性肝癌及35例原发性肝癌患者的血清AFU。结果原发性肝癌组的血清AFU浓度和阳性率显著高手其他各组。结论血清AFU对原发性肝癌的诊断有重要价值。     

Occupational injury and illness in the semiconductor manufacturing industry

Two thousand nine hundred and ninety-four reports of OSHA-reportable occupational injury or illness cases in 1984 from member companies of a national trade association of semiconductor manufacturing firms were analyzed. The 37 participating manufacturing facilities represented 16 companies employing over 95,000 persons, or approximately one-third of the U.S. work force for this industry in 1984. The annual incidence rate for all reportable injuries and illnesses was 2.7 per 100 full-time employees (FTE) for men and 3.7 per 100 FTE for women. Strains, sprains, or dislocations were the most frequently reported incidents (N = 956 [31.9%]), followed by cuts, lacerations, punctures, scratches, and abrasions (N = 445 [14.9%]), and chemical burns (N = 401 [13.4%]). Increased work-loss days per case were associated with manufacturing sites that did not have an employee health clinic on the premises, with custodial occupations, and with female gender.     

Primary malignant melanoma: a rare cause of mediastinal mass

A case of primary malignant melanoma in the mediastinum presenting as recurrent laryngeal nerve palsy is reported. Tissue biopsy at mediastinotomy yielded a diagnosis of malignant melanoma. The mass was fixed to the left aspect of the trachea and to the upper border of the left main bronchus and could not be removed surgically. Further extensive clinical and radiological investigations revealed no evidence of tumor elsewhere in the body.
