Bartonella henselae is associated with a wide spectrum of clinical
manifestations, including cat scratch disease, endocarditis and meningoencephalitis,
in immunocompetent and immunocompromised patients. We report the first molecularly
confirmed case of B. henselae infection in an AIDS patient in state
of Rio de Janeiro, Brazil. Although DNA sequence of B. henselae has
been detected by polymerase chain reaction in a lymph node biopsy, acute and
convalescent sera were nonreactive. 相似文献

Objectives: The concept of platform switching has been introduced to implant therapy, however long‐term data are sparse. The aim of this study was to biochemically investigate the inflammatory response mediated by MMP‐8 to platform switching after 3 years of loading, in order to understand the long‐term effect of implant/abutment mismatching on peri‐implant health. Methods: A total of 70 implants had been inserted in the posterior maxilla in 26 patients and were randomly assigned to one of the four treatment regimens (implant diameter 3.8 [control group], 4.3 [Test group 1, T1], 4.8 [Test group 2, T2] and 5.5 mm [Test group 3, T3]). All implants were restored using a 3.8 mm abutment. In the test groups, this restoration resulted in a mismatching of 0.25–0.85 mm of implant–abutment diameters. Results: Thirty‐six months after prosthetic rehabilitation, peri‐implant sulcular fluid samples were taken from two aspects of all implants and from periodontally healthy adjacent teeth. Samples were processed in a conventional ELISA using monoclonal antibodies recognizing the active entity of MMP‐8. In the test groups, MMP‐8 mean values were 2.76 ng for T1 (SD: 2.91), 3.30 ng for T2 (SD: 1.94) and 3.18 ng for T3 (SD: 2.46). For the control group, MMP‐8 mean value was 3.6 ng (SD: 2.23), whereas 3.38 ng (SD: 2.2) was recorded at the adjacent teeth. There were no statistically significant differences in MMP‐8 values between the groups (P=0.113, Kruskal–Wallis). Conclusions: The presence of an implant/abutment mismatching specific for this prosthetic concept is compatible with long‐term peri‐implant health as demonstrated by analysis of a sensitive biomarker of the peri‐implant inflammatory response. 相似文献

This is the second part of a two‐part piece on self‐adhesive resin cements; Part I was presented in the previous issue of the Journal. Here in Part II, the specific topics concerning self‐adhesive cements are clinical performance, post‐cementation sensitivity, and cementation of endodontic posts. 相似文献

Nodding Syndrome is a poorly understood neurologic disorder of unknown aetiology that affects children and adolescents in Africa. Recent studies have suggested that the head nods are due to atonic seizures and Nodding Syndrome may be classified as probably symptomatic generalised epilepsy. As part of the Ugandan Ministry of Health clinical management response, a multidisciplinary team developed a manual to guide the training of health workers with knowledge and skills to manage the patients. In the absence of a known cause, it was decided to offer symptomatic care. The objective is to relieve symptoms, offer primary and secondary prevention for disability and rehabilitation to improve function. Initial management focuses on the most urgent needs of the patient and the immediate family until ‘stability’ is achieved. The most important needs were considered as seizure control, management of behavioural and psychiatric difficulties, nursing care, nutritional and subsequently, physical and cognitive rehabilitation. This paper summarises the processes by which the proposed guidelines were developed and provides an outline of the specific treatments currently being provided for the patients. 相似文献

Objective Diabetes is associated with pulmonary tuberculosis (TB), possibly due to impaired immunity, and diabetes may exacerbate the clinical manifestations of TB. Our aim was to assess the role of diabetes in the clinical manifestations of TB. Methods We studied 1250 patients with pulmonary TB in an urban population in a cross‐sectional study in Tanzania. All participants were tested for diabetes and HIV co‐infection, and TB culture intensity was assessed. Levels of white blood cells, haemoglobin, acute phase reactants, CD4 count and HIV viral load were measured, and a qualitative morbidity questionnaire was used to identify the prevalence of disease‐related symptoms. Results Tuberculosis patients with diabetes had a higher neutrophil count (B 0.5 × 109 cells/l, 95% CI 0.2; 0.9, P = 0.001) than non‐diabetic TB patients. Serum C‐reactive protein (B 18.8 mg/l, CI 95% 8.2; 29.4, P = 0.001) and alpha‐1‐acid glycoprotein (B 0.2 g/l, CI 95% 0.03; 0.3, P = 0.02) were similarly higher in patients with diabetes. Diabetes did not affect culture intensity or HIV status, but self‐reported fever was three times higher among participants with diabetes than in those without diabetes (OR 2.9, CI 95% 1.5; 5.7, P = 0.002). Conclusion Diabetes is associated with small changes in the manifestations of TB, but may have little clinical significance. 相似文献

OBJECTIVE: To assess subjective intensities of pain during supragingival calculus removal employing ultrasonic scaler tips of two different shapes. MATERIAL AND METHODS: Twenty patients were treated using a piezoelectric ultrasonic device (Sirosonic L) and two different scaler tips representing a conventional (Instrument No. 3) and a slim-line style (Perio Pro Line Instrument SI-11) in a split-mouth design. Pain was recorded during calculus removal at intervals of 0.5 s employing an inter-modal intensity comparison. Additionally, a visual analogue scale was used for evaluation directly after the treatment procedure. Treatment time was recorded to assess the efficiency of calculus removal. RESULTS: Pain assessment during treatment showed that the slim-line scaler tip (median pain score: 1.4 [U], maximum: 3.5 [U], minimum: 0 [U]) caused less pain than the conventional device (median pain score: 7.8 [U], maximum: 14.7 [U], minimum: 0 [U]) (p<0.05). These results could be confirmed by the visual analogue scale. Treatment with the slim-line tip took significantly longer than treatment with the conventional tip (p<0.05). CONCLUSIONS: Using slim-line-styled ultrasonic scaler tips for supragingival calculus removal, painful sensations can be reduced compared with conventional ultrasonic devices. Thus, it might be possible to increase the patient's compliance during dental treatment with oscillating instruments. 相似文献
