Diagnosis of peritonsillar infections: a prospective study of ultrasound, computerized tomography and clinical diagnosis

AbstractPeritonsillar infections include cellulitis and abscess (quinsy). Clinical diagnosis is often supplemented by diagnostic drainage (aspiration or incision) in an effort to distinguish abscess from cellulitis. In a prospective study of 14 patients we have shown that clinical impression alone is unreliable (sensitivity 78 per cent, specificity 50 per cent). Computerized tomography (CT) (sensitivity 100 per cent, specificity 75 per cent) and intraoral ultrasound (sensitivity 89 per cent, specificity 100 per cent) are much more reliable. We propose that intraoral ultrasound could play a useful role in the clinical assessment of peritonsillar infections helping to improve accuracy in distinguishing abscesses from cellulitis.

A Prospective Study

A prospective study of over 100 cases comparing computerized tomography (CT) and correlating these studies with photographic motion picture studies of the larynx, conventional tomography and contrast laryngography has been performed. The authors give illustrative examples of cases in which the CT scan has been documented as providing equal and oftentimes greater information concerning not only tumors, but also cystic lesions and traumatic lesions. With the newer technology, the reduced radiation (which is less than one half that of conventional tomography), and the decreased expense (now comparable to that of laryngography alone), eliminates the need for conventional laryngography and tomography examinations. The incorporation of motion picture documentation of the lesions allowing future comparative studies between the original lesion and the CT are recommended for a more accurate retrospective classification and assessment of therapeutic results.

A Prospective Study

Aim. The aim of the study was a clinical assessment of the integrated determination of predictors of life-threatening ventricular arrhythmias (LVA) in patients with ventricular extrasystole (VE) without structural changes in the heart to predict the development of cardiovascular disease in a prospective study. Material and methods. From 1997 to 2014 199 patients with neurocirculatory dystonia (NCD), complicated with VE II-V class EE at the age of 18-35 years (mean 27.3-2.6 years) were observed in District Military Clinical Hospital of the Ministry of Defense of the Russian Federation, City Hospital named after St. Martyr Elizabeth. All patients, in addition to a general clinical examination, determined late potentials of the ventricles (LPV), QT interval variability (QTd), heart rate turbulence (HRT), and also indicators reflecting the possible mechanism of VE development. Results. The results of the study showed that in patients with NCD complicated by VE, the detection of indicators reflecting the presence of VE caused by the mechanisms of early post-depolarization and re-entry is a predictor of the development of coronary heart disease (CHD) and hypertension (HB). The positive prognostic significance of the indicators showing the presence of VE with these development mechanisms for the development of CHD and HB averaged 74% and 44% respectively, and with the appointment of сlass III drugs for elimination of VE and (or) development of unstable ventricular tachycardia, the risk of developing CHD increased to an average of 93%. Identification of NDC patients with indicators reflecting the presence of VE due to delayed post-depolarization is a predictor of the development of gastrointestinal tract (GT) diseases with positive prognostic significance, averaging 61%. Positive prognostic significance with respect to the development of CHD, HB, GT diseases for the detected LPV, QTd > 80 ms, pathological values of HRT VE did not exceed 30%. Indicators and predictors, which characterize the mechanism of development of VE and the risk of LVA occurrence in patients with NCD complicated by VE, were highly correlated (r > 0.50) with risk factors for cardiovascular and gastrointestinal system diseases.
