A clinical approach for cardiovascular monitoring of HIV-infected patients. Results from an observational cohort study.

BACKGROUND: HIV infection is one of the leading causes of acquired heart disease. Because of its high diffusion, systematic echocardiographic monitoring has been proposed to exclude cardiovascular involvement in these patients. The aim of this study was to evaluate an alternative clinical approach by which echocardiographic screening is limited to patients with a clinical suspicion of heart disease. METHODS: We studied 2030 consecutive HIV-infected patients admitted to a tertiary referral hospital (group A). History, physical examination, ECG, and chest X-ray were used to screen HIV-infected patients for cardiovascular involvement. Selected patients were extensively studied, first of all by echocardiography. Cardiovascular and non-cardiovascular deaths were recorded: RESULTS: Cardiovascular involvement was clinically suspected in 201 patients (9.9%; group B). Among them a higher extracardiac mortality was found in presence of pericardial disease (odds ratio [OR] 4.27, 95% confidence interval [CI] 2.01-9.09), while a higher cardiovascular mortality was recorded for patients with cardiomyopathy or myocarditis (OR 2.72, 95% CI 1.09-6.81), and right ventricular dysfunction and/or pulmonary hypertension (OR 4.67, 95% CI 1.44-15.2). Compared with group A, patients in group B had a significantly increased cardiac death rate (0.114 vs 0.018, p < 0.001). A positive echocardiogram slightly increased this rate (from 0.114 to 0.164, p = NS), whereas a negative echocardiogram significantly decreased the cardiac death rate (0.015 vs 0.164, p = 0.004). CONCLUSIONS: Clinical selection of HIV-infected patients with suspected cardiovascular involvement may help identify patients with higher frequency of cardiovascular involvement. Among these patients, echocardiography may be a useful screening tool in those at high risk for cardiovascular death.     

Flabby ridge correction using an auxiliary technique with connective tissue graft

A common finding in patients with edentulous maxilla and partially dentate mandible is mainly the presence of flabbiness in the anterior edentulous alveolar ridge that can compromise the retention and stability of a denture. Thus, this case report presents the correction of a flabby ridge, using an auxiliary technique combining surgical excision and autogenous connective tissue grafting. The technique improved the quality of the osteomucosal support of the alveolar ridge and increased the vestibule deepness, whose result increased the success rate of the new conventional total prosthesis.     

Use of the connective tissue graft for the coverage of composite resin-restored root surfaces in maxillary central incisors

The purpose of this article is to report the use of the subepithelial connective tissue graft technique combined with the coronally positioned flap on a composite resin-restored root surface to treat Miller Class I gingival recessions associated with deep cervical abrasions in maxillary central incisors. Clinical measurements, including gingival recession height, probing depth, and bleeding on probing (BoP), were recorded during the preoperative clinical examination and at 2, 6, 12, and 24 months postoperatively. During the follow-up periods, no periodontal pockets or BoP were observed. The periodontal tissue of the teeth presented normal color, texture, and contouring. In addition, it was observed that creeping attachment had occurred on the restoration. This case report shows that this form of treatment can be highly effective and predictable in resolving gingival recession associated with a deep cervical abrasion.
