Objective: Documenting adverse remodeling in absence of left ventricular outflow tract (LVOT) obstruction and mitral regurgitation in a classical hypertrophic cardiomyopathy (HCMP) phenotype is difficult. Changes in the left atrium (LA) are a consequence of progressive left ventricular (LV) fibrosis and have been shown to progress in a linear fashion. Therefore, studying LA changes for identifying adverse remodeling in HCMP patients is important. Materials and Methods: This was a prospective study which included HCMP patients and age- and gender-matched controls. Various echocardiographic parameters of adverse cardiac remodeling were investigated. Results: A total of 160 patients with HCMP and 75 age- and sex-matched controls were analyzed over a 5-year period. HCMP patients had an enlarged LA, greater segmental thickness, and mildly increased LV filling pressure. Patients with maximum LA volume >40 mL and global LA strain <21.5% showed greater maximum segmental thickness and increased ratio of pulse wave Doppler derived mitral E wave and tissue Doppler derived annular e wave with reduced LA strain and LV strain, LA emptying fraction, and strain-derived LV ejection fraction. In both groups, significant difference was not observed in age, sex, HCMP phenotype, presence or absence of LVOT obstruction, LV volume, and mitral Doppler ratio of pulse wave Doppler derived mitral E and A waves. Conclusion: Monitoring HCMP in asymptomatic patients is challenging. Assessment of adverse cardiac remodeling in classical HCMP phenotype is feasible using global LA strain and maximum LA volume. Global LA strain identifies early changes and maximum LA volume late changes of cardiac remodeling and therefore provide an early indication of disease progression in asymptomatic HCMP patients.

Background: Extrusion of debris is a major factor that results in postoperative pain during root canal treatment with various instruments and instrumentation techniques. Therefore, instrumentation techniques that extrude minimal debris into the periapical area while reducing pain are desirable. This study aimed to compare the incidence of postoperative pain and intake of analgesic medication (frequency and quantity) after endodontic treatment of mandibular posterior teeth using two single files and full-sequence continuous rotary systems with different kinematic motions. Methods: Thirty-five of 105 patients were assigned equally to three groups according to the instrumentation system used: ProTaper Next (PN) X2, 25/06 (Dentsply, Maillefer, Ballaigues, Switzerland), One Shape (OS), #0.25/06 (Micro Mega, Besancon, France), and Wave One Gold (WG), Red - #0.25, 0.07 (Dentsply, Maillefer, Ballaigues, Switzerland). Five specialists were included in this study design; each professional prepared 21 teeth, and randomly selected 7 per instrument system. The VAS sheet ranging from 0 to 10 was used to record the initial and postoperative pains at 24, 48, and 72 h, and 7th day after single visit endodontic treatment in mandibular premolars and molars with a diagnosis of asymptomatic irreversible pulpitis with or without apical periodontitis. Postoperatively, an analgesic, ibuprofen 400 mg was administered for intolerable pain at a dose of 1 tablet for 6 h. The patients were asked over the telephone regarding postoperative pain at intervals of 24, 48, and 72 h, and 7th day using a visual analogue scale. Result: There were no statistically significant differences among the PN, OS, and WG systems (P > 0.05) with regard to the incidence of postoperative pain at any of the four time points assessed. Conclusion: The intensity of postoperative pain, frequency, and analgesic intake were similar across all three types of instrument systems; however, the reciprocating single file (WG) was associated with less postoperative pain than the full sequence continuous rotary file.
