Ozone and Laser Effects on Dentin Hypersensitivity Treatment: A Randomized Clinical Study.

Introduction: The aim of this study was to evaluate and compare the clinical efficacy of diode laser and ozone gas in the treatment of dentin hypersensitivity (DHS).

Methods: One hundred thirty-two teeth from 44 patients with moderate DHS were randomized into 3 groups according to a split-mouth design. In the diode laser group, the operator irradiated the superficial dentin exposed with an 808-nm wavelength and incremental power from 0.

Clinical and Patient-reported Outcome Measures in Men Referred for Consideration of Surgery to Treat Lower Urinary Tract Symptoms: Baseline Results and Diagnostic Findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM).

Background: Clinical evaluation of male lower urinary tract symptoms (MLUTS) in secondary care uses a range of assessments. It is unknown how MLUTS evaluation influences outcome of therapy recommendations and choice, notably urodynamics (UDS; filling cystometry and pressure flow studies).

Objective: To report participants' sociodemographic and clinical characteristics, and initial diagnostic findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM).

Patient-specific risk of undetected malignant disease after investigation for haematuria, based on a 4-year follow-up.

Objectives: • To estimate the diagnostic accuracy of a guidelines-based haematuria clinic protocol by measuring the incidence of undetected malignancy during a follow-up period. • To estimate an individual's post-test risk of having undetected malignancy using the protocol likelihood ratio and the population prevalence of disease.

Methods: • Data were collected prospectively on a cohort of 4020 consecutive patients who were referred to a 'one-stop' haematuria clinic between 1998 and 2003.

A prospective analysis of the diagnostic yield resulting from the attendance of 4020 patients at a protocol-driven haematuria clinic.

Objective: To clarify the prevalence of disease as determined by age, sex and the degree of haematuria at presentation, and to ascertain the merits of using ultrasonography (US), i.v. urography (IVU) or both when imaging the upper urinary tract, in a prospective cohort of patients attending a protocol-based haematuria clinic.
