原发性骨质疏松的诊断首先要除外继发性骨质疏松。后者包括的范围很广,内容也很多,需要广博的内科学基础和辨证的逻辑思维才能予以正确鉴别。骨密度检查只能作为一种参考,而不能作为诊断原发性骨质疏松的唯一依据。 相似文献

An important operational aspect of Syringe Exchange Programmes (SEPs) is the venue of service delivery. This report describes the programmatic features of the Sacramento Area Needle Exchange (SANE), an illegal SEP operating in California, USA. SANE utilises “satellite exchangers” to distribute the bulk of its syringes and HIV risk reduction supplies. Advantages of relying primarily on Designated Exchangers (DE) for delivery of SEP services are that it: (1) allows for coverage of a large geographical area; (2) keeps operational cost low; (3) provides syringes to clients who may not want to or cannot use fixed site programmes; (4) limits the possibility of detection of programme personnel and clients by law enforcement. Limitations are that: (1) it is not as conducive as fixed sites to providing a wide range of ancillary services; (2) it may not be optimal for drug users who do not want to be reliant on other people for access to syringes; (3) those who receive services from a satellite exchanger may not derive as much counselling and referral services as direct exchangers. The lack of legal status, political support and adequate funding threatens the programme’s existence. 相似文献

Two adult patients with the diagnosis of gastric lymphoma who developed adenocarcinoma of the stomach 8 years after the treatment are presented. Both patients were treated by subtotal gastrectomy followed by irradiation of 4,000–4,500 cGy to the epigastric region and six courses of chemotherapy (vincristine, cyclophosphamide, prednisolone). In our review of the literature, 16 cases of gastric adenocarcinoma following the treatment of gastric lymphoma were found and listed with details. The factors influencing the development of this secondary carcinoma, mainly those treatment related are discussed. The possible role of both radiotherapy and chemotherapy in shortening the latent period for the development of stump carcinoma is emphasized. © 1993 Wiley-Liss, Inc. 相似文献

Inanimate structures cannot detect and repair their fatigue damage or microdamage, so to minimize it they need more structural
material and strength. Living bone handles this matter differently. Bone modeling drifts adapt bone architecture and strength
to the loads on bones in ways that tend to keep strains from exceeding a “modeling threshold” range. Strains (or equivalent
features) above that threshold switch mechanically controlled modeling ON. Where strains stay below that threshold, this modeling
goes OFF. Repeatedly loading-deloading a bone causes microdamage in it, and basic multicellular unit (BMU)-based bone remodeling
normally repairs it. Where strains stay below an operational “microdamage threshold,” remodeling can repair whatever microdamage
happens for as long as it happens. Strains above that threshold can cause too much microdamage to repair completely and lead
to fatigue fractures of trabeculae or whole bones. The modeling threshold normally lies comforably below the microdamage threshold.
Since modeling normally adjusts bone architecture to keep strains from exceeding the modeling threshold, this keeps strains
below the microdamage threshold, too, and voluntary activities do not cause more microdamage than remodeling can repair. Therefore,
long-distance runners do not need more bone mass and strength than nonrunners of comparable age, sex, and body size. 相似文献

Summary A retrospective analysis of 183 consecutive patients operated on for ruptured cerebral aneurysms and surviving at least one year revealed appearance of postoperative epilepsy in 14 cases (8 per cent) on an average of 10 months (range 0–23 months) after the operation. Factors associated with the development of secondary epilepsy were localization of the aneurysm on the middle cerebral artery, temporary clipping intraoperatively, wrapping technique to treat the aneurysm, and vasospasm seen on the postoperative control angiogram. Intraoperative and/or postoperative ischaemia seems to be the crucial phenomenon favouring the development of epilepsy. Identification of the risk factors may help to focus the anti-epileptic prophylaxis in cases prone to develop seizures. 相似文献

BACKGROUND: Acquired cerebriform intradermal naevus (CIN) is a rare form of pseudo cutis verticis gyrata. CASE REPORT: A case of acquired CIN of the scalp in a 46-year-old male patient is presented. The clinical and histopathological presentations of CIN are described and the therapeutic possibilities are discussed. CONCLUSIONS: In each individual case the physician must decide whether to do surgery or follow a wait-and-see policy. There is little risk of malignant change of CIN, and surgical excision of such lesions often involves evident mutilation. 相似文献
