Tolonium Chloride

Background: Oral cancer burden in developing countries is huge. In Bangladesh and India incidence were 10.6% and 10.4% respectively on 2018. At the same time worldwide incident was only 2%. Majority patients present at advanced stage and their survival rate is poor. Diagnostic delay from patient side and health delivery system side is significantly longer and it is more in developing countries. Like other malignancy early diagnosis can save a lot of these patient. Methods: This prospective study was carried out in Khulna Medical College Hospital from July 2017 to July 2019. Patients who will meet the criteria for this prospective study and capable and willing to give informed consent were enrolled. 20 second rinse/gargle with 10ml of 1% Tolonium chloride solution was done. Biopsy were taken from stained lesion, biopsy report were compared with TC stained lesions. Results: Out of 1650 patients in our outdoor department for various problem and only 30 cases were selected for this study according to selection criteria. Of 30 patients, 18 (60%) were male and 12 (40%) were female. The male-to-female ratio was 3:2. It was found that the sensitivity of 1% Tolonium Chloride rinse for oral precancer and cancer detection was 83.33%, whereas the specificity was 84.21%. Conclusion: Tolonium chloride rinse is a good screening test for oral cancer diagnosis with sensitivity 83.33% and specificity 84.21%. Bangladesh J Otorhinolaryngol; April 2020; 26(1): 11-17

Myocardial contractility of the left ventricle (LV) plays an essential role in maintaining normal pump function. A recent ex vivo experimental study showed that cardiomyocyte force generation varies across the three myocardial layers of the LV wall. However, the in vivo distribution of myocardial contractile force is still unclear. The current study was designed to investigate the in vivo transmural distribution of myocardial contractility using a noninvasive computational approach. For this purpose, four cases with different transmural distributions of maximum isometric tension (Tmax) and/or reference sarcomere length (lR) were tested with animal-specific finite element (FE) models, in combination with magnetic resonance imaging (MRI), pressure catheterization, and numerical optimization. Results of the current study showed that the best fit with in vivo MRI-derived deformation was obtained when Tmax assumed different values in the subendocardium, midmyocardium, and subepicardium with transmurally varying lR. These results are consistent with recent ex vivo experimental studies, which showed that the midmyocardium produces more contractile force than the other transmural layers. The systolic strain calculated from the best-fit FE model was in good agreement with MRI data. Therefore, the proposed noninvasive approach has the capability to predict the transmural distribution of myocardial contractility. Moreover, FE models with a nonuniform distribution of myocardial contractility could provide a better representation of LV function and be used to investigate the effects of transmural changes due to heart disease.

1. Average supine circulating total catecholamine concentrations were found to be higher than the normal range in about 50% of patients with labile hypertension and in about 30% of patients with sustained essential hypertension. 2. These higher resting concentrations were mainly due to an increase in adrenaline in labile hypertension and to an increase in noradrenaline in sustained hypertension. 3. Patients with elevated catecholamine concentrations were also characterized by a higher heart rate, by an increased myocardial contractility and by greater hypotensive response after treatment with β-adrenoreceptor blocking agents. 4. These studies suggest the existence of subgroups of hypertensive patients with increased sympathetic tone.
