Body weight in patients with Parkinson's disease.

There is some evidence suggesting that Parkinson's disease (PD) patients exhibit lower body weight when compared to age-matched healthy subjects. Low body mass index (BMI) is correlated with low bone mineral density, both of which are major risk factors for hip fractures. Possible determinants of weight loss in PD patients include hyposmia, impaired hand-mouth coordination, difficulty chewing, dysphagia, intestinal hypomotility, depression, decreased reward processing of dopaminergic mesolimbic regions, nausea, and anorexia as the side effects of medication, and increased energy requirements due to muscular rigidity and involuntary movements. It is unclear whether PD patients in general, or only a subgroup of those affected, definitely show lower BMI in the advanced stages of the disease. We therefore recommend that the body weight of PD patients be monitored monthly as the disease progresses, and that a patient's nutrition should be supplemented with sufficient amounts of vitamin D and calcium to reduce the risk of hip fractures and strengthen bone density. Because meal times may coincide with unpredictable off periods associated with akinesia and impaired hand-mouth coordination, PD patients also need flexible food schedules that accommodate the associated symptoms of this disease.     

The multiform and variable patterns of onset of orofacial granulomatosis

BACKGROUND: The recurrent chronic orofacial swelling caused by orofacial granulomatosis (OFG) can cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Although the enlargement of the lips is described to be the most common presenting complaint, the clinical onset of OFG may be characterized by minor associated mucosal and neurological manifestations, making early diagnosis very difficult or, sometimes, merely presumable. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations of 19 patients with OFG, who were examined at our institution between 1998 and 2002, in order to determine their initial manifestations and presenting symptoms. RESULTS: A total of 10 patients showed classical recurrent enlargement of the lips (six lower; four upper) as presenting symptom. In the other nine patients, OFG onset was characterized by transient unilateral facial nerve palsy (two cases), intraoral manifestations (two cases), recurrent swelling of the periorbital area (two cases), of the chin (one case), of the zygomatic area (one case), and of the cheeks (one case). CONCLUSION: Our data underlined that OFG onset could be frequently characterized by widely variable, multiform, and temporary clinical findings. Involvement of atypical sites of the orofacial region and presence of single minor manifestations may occur as presenting symptoms, often preceding the development of traditional clinical findings.     

Wild Edible Plants and Their Traditional Use in the Human Nutrition in Bosnia-Herzegovina

This article presents first systematical procedure results on traditional usage of wild, edible, vitaminous, and aromatic plants in the nutrition of human population in Bosnia and Herzegovina (W. Balkan peninsula; SE Europe). By method of an ethnobotanical interview, which comprised of over 250 persons, whose average age was 55, and by research on edible wild flora all around Bosnia and Herzegovina that extended over many years, detected were 308 plants belonging to 73 plant families that are being used in nutrition and diet of indigenous population. Edible wild plants are used as delicious vegetables, fruits, peer and spices, in either fresh, raw, or dried condition. Plants are being used for the making of cooked food (33%), fresh salads (19%), mush and bread (17%), or as fresh, wild fruits and drinks (13%) or as spices and ethno-pharmacological potions (10%). The majority of identified, wild edible plants may satisfy the daily human need for elementary nutrition material, particularly those of vitamins C and A, and for some minerals, according to the regulations of World Health Organization (WHO).     

早期干预对高危儿在婴儿早期发育的影响

目的：探讨早期干预对高危儿在婴儿早期发育的影响。方法：采用自行设计的一套早期干预方法通过指导家长对实验组实施，分别在3个月、6个月时进行格体生长和行为发育的评估，另设对照组进行比较。结果：实验组和对照组在体重、身长、头围方面均无统计学差异，但实验组的5个能区行为发育商均值都高于对照组，除3个月的语言能区外，其余均有统计学差异。结论：早期干预在婴儿早期就能促进高危儿的行为发育，但对促进高危儿的体格生长无明显效果。     

Patient readiness for return to home: Discord between expectations and reality

This study examined the interface between acute hospital care and return to home in relation to elderly patients' perceived ability and preparedness to cope at home. Seventy-six (n = 76) elderly patients aged 60 years and over were randomly recruited from a large Queensland hospital and interviewed prior to discharge about their perceived health, functional status and their ‘readiness’ to cope at home. They were followed up at home 7–10 days post-discharge. Comparisons were made between a number of measures at discharge and post-discharge. Although the majority of patients indicated that they would cope very well upon discharge, a large number of patients reported experiencing considerable difficulty with activities of daily living, particularly instrumental activities of daily living prior to and especially after discharge. The self-reported health status of patients similarly deteriorated between discharge and follow-up. Despite a large number of patients experiencing functional limitations, few were referred to hospital or community-based therapy services. Some policy implications are explored.

低剂量石英对大鼠肺泡灌洗液的早期影响

用支气管肺泡灌洗法研究低剂量石英对大鼠肺脏的影响。大鼠分别注尘2、10mg观察1、7、21天。结果表明低剂量石英可使灌洗液中细胞总数、有核细胞/红细胞比值、肺泡巨噬细胞显著增高,特别是泡沫型肺泡巨噬细胞随时间延长而明显增高。染尘动物灌洗液中蛋白、乳酸脱氢酶、碱性磷酸酶呈一过性升高,酸性磷酸酶在2mg石英组呈一过性升高,但在10mg石英组却持续上升。实验结果表明,肺泡巨噬细胞及其溶酶体膜的破坏在矽肺发生早期可能起一定的作用。     

贲门癌术中留置金属导芯硅胶鼻肠管的临床研究

目的探讨贲门癌术后早期肠内营养的可行性、安全性及临床效果.方法贲门癌患者术中留置金属导芯硅胶鼻饲管,术后第1天开始肠内营养支持,术前及术后第10天,分别测量体重,检测血红蛋白浓度及肝肾功能,观察肠内营养的副作用.结果全组鼻饲管留置时间平均15.2 d;术后早期肠内营养明显增加了营养物质的摄入量,术后无明显的体重丢失,未见需要终止治疗的并发症.结论早期肠内营养治疗具有符合生理、减少医药费用等优点,该置管方法安全、简便,达到了加强术后患者营养支持的目的,可列入术后常规应用.     

核酸及核苷酸用于营养及免疫调节治疗的早期卫生技术评估

目的 评价核酸或核苷酸用于临床营养支持和免疫调节治疗的安全性、有效性和经济学价值。方法 检索中国生物医学文献数据库、Cochrane图书馆、MEDLINE光盘数据库、EMBASE光盘数据库,并联机检索SCI数据库,鉴定有关随机对照试验(RCTs),采用RevMan4.l进行Meta-分析。结果 纳入46个随机对照试验,涉及核酸/核苷酸用于肠内营养支持、婴儿营养、免疫调节治疗。18个研究报告了含核苷酸组分的免疫增强型肠内营养对外科术后和危重症患者预后的影响,合并分析发现免疫营养对患者感染率、住院时间和费用有肯定意义。发现1个报告在母乳代用品中加入核苷酸对婴儿免疫功能影响的研究,但报告对临床结局无明显影响。27个对“免疫核酸”用于免疫调节治疗的随机对照试验均为低质量研究,合并分析无法肯定iRNA的临床价值。结论 在外科术后患者应用免疫肠内营养制剂可降低感染率、缩短住院时间并可能减少住院费用,但不能确定作为组分之一的核苷酸的作用。尚无证据支持在母乳代用品中添加核苷酸具有临床意义。不能肯定免疫核酸是否具有免疫调节作用,亦未发现核酸在延缓衰老、改善老年人健康状况方面的可用证据。建议对核酸、核苷酸用于营养支持治疗和免疫调节治疗进行进一步研究,严格规范“核酸营养品”的宣传和应用。
