结节病是一种罕见的和潜在的致残儿科疾病。此病临床治疗困难,需要长期监测。我们报告了1例9岁的白人女孩的情况,就诊最初表现为双侧慢性前葡萄膜炎、白内障和继发于结节病的青光眼。在过去的2a,患者接受左布诺洛尔滴剂,局部和全身类固醇治疗,随后要求折叠式人工晶状体植入。在白内障手术后的2mo,患者葡萄膜炎以局部类固醇和低剂量甲氨蝶呤一直控制良好。她全血计数和肾功能定期监测,没有甲氨蝶呤不良影响的报告。结节病是一多系统疾病,需要眼科学家,神经学家和儿科医师多学科的投入。内科和外科治疗本病富于挑战。本例强调了低剂量甲氨蝶呤在儿童慢性葡萄膜炎治疗中的安全性和对此病及时治疗以防止显著发病的需要。 相似文献

A qualitative investigation into why patients change their GPs 总被引:3,自引:2,他引:1
BACKGROUND: In the past patients have rarely changed doctor. The UK
Government has made such change easier and it appears to be becoming more
common. Changing doctor without changing address may be indicative of
dissatisfaction with the GP service. Previous research in this area has
been largely quantitative. OBJECTIVE: To identify why patients change their
GP although they have not moved house. METHOD: Qualitative investigation of
patients' experiences. In depth interviews of 24 patients were conducted to
determine why they had left their previous doctor. Letters describing the
process of change were received from a further 17 patients. Analysis was
performed using standard qualitative techniques. RESULTS: The decision to
change was in most cases multi- factorial. Interviews yielded more detailed
and richer accounts than letters. For interviewees, rudeness or the
attitude of the doctor was the commonest reason. Overall, 19 different
reasons, in four categories, were identified. The largest single category
was accessibility, closely followed by attitudinal problems. Clinical
issues and personal characteristics of the doctor were less common. The
majority of those responding by letter gave only one reason, usually
distance. CONCLUSION: Patients change doctor after careful consideration
and commonly for interpersonal reasons. There is usually one critical
factor in the decision to change. Factors may be modifiable or
non-modifiable. Critical event audit may enable GPs to analyse the reasons
why patients leave their lists.

文献中化学药物对变形杆菌代表性菌种,主要是部分吲哚阴性和吲哚阳性变形杆菌属的抗菌活性已有报道。在吲哚阴性变形杆菌中除奇异变形杆菌外,还有Proteus penner,在吲哚阳性变形杆菌中除普通变形杆菌外,还有摩氏变形杆菌和普罗威登斯菌。各种变形杆菌对化学药物的敏感性不同。然而,它们对化学药物敏感性取决于其来源的报道不多。因此,我们用分离自不同病理材料的变形杆菌培养物对β-内酰胺类和氨基糖苷类抗生素的敏感性进行了研究。对1985年分离自各种病理材料的130株变形杆菌菌株培养物进行了敏感性测定,其中分离自脓汁30株,分离自各种化脓炎症性疾病患者的尿和急性肠道感染患者的粪各50 相似文献

A model for a clinical competency examination has been presented. Extensive efforts were exerted in standardizing the procedures, the criteria, and the examiners. In addition, the examination was designed to permit isolation and documentation of errors in various phases of a class II amalgam restoration. 相似文献

OBJECTIVE: Oral ulceration occurs in an estimated 2–4% of patients with HIV infection. This retrospective observational study describes the aetiology and characteristics of 94 HIV-positive patients with either severe and/or recurrent oral ulceration presenting at a dedicated HIV dental unit over a 4-year period. METHODS: Case records were reviewed for diagnosis investigations, CD4 count, CDC stage and treatment modality. RESULTS: Of the 94 patients 50% had an AIDS diagnosis. In patients with asymptomatic HIV disease minor recurrent oral ulceration was the commonest diagnosis whilst large non-specific neutropenic ulcers were more frequently seen in patients with symptomatic disease with low CD4 counts. A variety of treatment modalities were used including thalidomide. An algorithm is presented for the management of patients with severe oral ulceration. 相似文献

Human bone marrow cells cultured for 21 days in the presence of recombinant human interleukin-3 (IL-3) produced up to 28 times more colony-forming cells (CFC) than could be obtained from cultures stimulated with granulocyte colony stimulating factor (G-CSF) or granulocyte-macrophage CSF (GM-CSF). IL-3-cultured cells retained a multipotent response to IL-3 in colony assays but were restricted to formation of granulocyte colonies in G-CSF and granulocyte or macrophage colonies in GM-CSF. Culture of bone marrow cells in IL-3 also led to accumulation of large numbers of eosinophils and basophils. These data contrast with the effects of G-CSF, GM-CSF, and IL-3 in seven-day cultures. Here both GM-CSF and IL-3 amplified total CFC that had similar multipotential colony-forming capability in either factor. G-CSF, on the other hand, depleted IL-3-responsive colony-forming cells dramatically, apparently by causing these cells to mature into granulocytes. The data suggest that a large proportion of IL-3- responsive cells in human bone marrow express receptors for G-CSF and can respond to this factor, the majority becoming neutrophils. Furthermore, the CFC maintained for 21 days in IL-3 may be a functionally distinct population from that produced after seven days culture of bone marrow cells in either IL-3 or GM-CSF. 相似文献

Pneumococcal disease is a major cause of morbidity and mortality in infants and young children worldwide. New pneumococcal conjugate vaccines include 7 to 11 serotypes, which are the most common cause of paediatric disease in most parts of the world. The efficacy of a 7-valent conjugate vaccine was 97.4% (95% CI, 82.7-99.9) against invasive pneumococcal disease, and 57% (95% CI, 44-67) against otitis media, caused by vaccine serotypes. Evidence shows that the vaccine has the potential to prevent pneumonia. Pneumococcal conjugate vaccination has also been shown to reduce nasopharyngeal carriage of vaccine serotypes (particularly serotypes associated with antibiotic resistance). Thus widespread use of pneumococcal conjugate vaccine could substantially reduce the burden of invasive disease and would have the potential to control the global spread of antibiotic resistance in pneumococci. Conclusion: It is important that these highly effective vaccines should be made available to children in the developing countries. 相似文献

Background: Third molar removal has been implicated as a precipitating event for temporomandibular joint disorders. The aim of this study was to determine what proportion of patients had pre‐existing pain and dysfunction that could be attributed to the temporomandibular joints. Methods: Sixty patients referred for third molar removal were clinically examined and a history of their presenting complaint recorded at the initial consultation visit. Patients were then diagnosed and categorized. Results: Of the total number of patients examined, 13.3 per cent showed signs and symptoms of temporomandibular joint pain and dysfunction while a further 23.3 per cent also had symptomatic third molar teeth. Conclusions: The results of this study suggest that the signs of temporomandibular joint disorders are common in patients referred for third molar extractions. 相似文献

Background: Accurate medical history information is essential for good patient care and should be notified in the letter of referral. The aim of this study was to investigate the subjective opinion that the medical information in a large number of referrals is either inaccurate or non‐existent. Methods: Medical histories from 54 patients with positive medical history findings upon taking the medical history at the initial consultation appointment were compared to the medical information supplied in the referral letter. Results: Overall, medical information was only 58.8% complete with dental referrals being 55.2% complete and medical referrals 62.4%. The majority of referral letters (70.4%) missed at least one relevant finding and only 29.6% of referrals were 100% complete. Conclusions: The results of this study suggest that the standard of referral letters needs to be improved as the received referrals were generally incomplete and contained inaccurate information. This highlights the need for each and every practitioner to take their own detailed medical history and not rely on the information supplied in the referral. 相似文献
