Published: April 2020

Background: Presbycusis is a hearing loss due to the degeneration process in elderly people of 65 years old and beyond, characterized by a decrease in hearing sensitivity in both ears. Reactive oxygen species (ROS) are assumed to have an important role in the pathogenesis of presbycusis. Purpose: To find out the correlation between ROS levels in plasma and hearing threshold levels in presbycusis patients. Method: The design was cross sectional and conducted at the Outpatient Clinic of Neurotology Division, Geriatric Clinic, Clinical Pathology Installation, and Central Installation of Biomaterials Network Bank of Dr. Soetomo Hospital. Samples were taken by consecutive sampling for audiometric examination and measurement of ROS levels in plasma. Results: Fifty samples were collected, ROS levels in plasma were found with mean (SD) of 2.46 ng/ml (0.84). The mean hearing threshold level was 47.70 dB (12.42). The Pearson statistical test revealed a significant correlation between ROS levels in plasma and hearing threshold levels, with p=0.003 (p<0.05), and the correlation coefficient (r) 0.41. Conclusion: There was a correlation between ROS in plasma and hearing threshold levels in presbycusis patients, with a significant moderate-positive correlation pattern. It indicated that the higher the ROS levels in plasma, the higher the hearing threshold levels in presbycusis patients. Latar belakang: Presbikusis adalah gangguan pendengaran akibat proses degenerasi yang dijumpai pada usia 65 tahun atau lebih, ditandai oleh penurunan kepekaan pendengaran pada kedua telinga. Reactive oxygen species (ROS) diduga mempunyai peran penting pada patogenesis presbikusis. Tujuan: Untuk mengetahui hubungan antara kadar ROS dalam plasma dengan nilai ambang dengar pada penderita presbikusis.

Published: April 2020

Objective: Oxidative stress has been considered to be one of the main causes for the development of pulmonary hypertension (PH) via leading alteration of pulmonary vasomotor tone induced by hypoxia. The aim of this study is to determine the serum paraoxonase-1 enzyme (PON-1) activity, arylesterase activity, the antioxidant-oxidant status in patients with PH and to compare with healthy controls.
Material and Methods: Thirty five healthy ındividuals (mean age 45.7±5.9 years) as a control group and thirty eight patients (mean age 46.5±12.6 years) with a diagnosis of PH wereincluded in thestudy. Serum PON-1 and arylesterase activity, the total antioxidative capacity of plasma (TAC) and total oxidantstatus (TOS) were measured by using colorimetric methods. The Oxidative Stress Index (OSI) wascalculated as TOS/ TACX100.
Results: Serum PON1 activity is significantly lower in PH patients when compared with healthy controls (p=0.001). The serum arylesterase activity and TAC, TOS and OSI status were similarin bothgroups. There is inverse correlation between serum PON1 activityand NYHA functionalcapacity (r:-0.649 p=0.001). Furthermore, PON1 activity of study patients are similarin the PH subgroups. Serum activity of PON1 wasfoundto bethe only independent parameter for the presence of PH in binary logistic regression analysis (OR 0.984, 95 % CI 0.977-0.992, p=0.001). Eight patients died follow up period (27.6±14.5 months) and none of theparametersincluding PON1 were associated with mortality.
Conclusion: Serum PON1 activity of PH patients is lowerthanhealthypopulation, but does not predictmortality.

Authors: Hossen Md Shafiul , Kar Auditi , Haque Hasan Moinul 
Published: April 2020

Objectives: Ringworm is a common cutaneous fungal disease with worldwide distribution.It may lead to the abnormal c-reactive protein levels and metabolism of lipid. Thus this study has been designed for determining serum CRP and also evaluating the Lipid profile in patients associated with ringworm.
Materials and methods: This study recruited 25 patients with ringworm (cases) and 25 healthy individuals (controls). A questionnaire of personal characteristics was completed for each patient and control. Inflammatory marker (CRP) and Serum lipid profile (total, lowdensity lipoprotein (LDL), high-density lipoprotein (HDL) cholesterol and triglyceride) was recorded for each case and control. The test of significance was applied for statistical analysis.
Results and discussion: The mean serum CRP were 1.608±0.14 and 0.648±0.03 mg/dl and total cholesterol level were 175.09±3.26 and 182.09±3.01 mg/dl in ringworm patients and control subject respectively. It was also observed that the serum TG; HDL; LDL levels were 131.76±3.07 and 139.84±3.47 mg/dl; 80.79±1.79 and 73.35±4.14 mg/dl; 67.95±4.64 and 86.55±3.70 mg/dl in patients and control group respectively. The value of CRP was significantly increased in patients compared to control group (p <0.05). There was no significant difference of lipid profile study between patients and control
Conclusion: Findings of this study indicate increased concentrations of CRP in patients affected to ringworm and its role in this infection. Patients should thus be routinely screened for such abnormalities Probably observation of lipid profile in healthy individuals in compare with patients group indicates that it has no relationship in case of ringworm.

Published: April 2020

Social changes, technological re-equipment, intensive formation of urban infrastructure have led to a constant increase in stress factors and an excessive growth of the nervous and psychological population burden. As a result of these processes in economically developed countries, acute diseases are becoming less and less significant, unlike the group of chronic disorders, such as arterial hypertension. Data from the review of the literature and the data we have received indicate that there is an increase in the level of cortisol in the blood in the phase of anxiety, which reduces in the resistance phase. A significant role is played by another hormone - insulin, which plays a key role in the development of the general adaptive syndrome. Through it the body implements numerous counter-defects in relation to the regulatory influence of catecholamines and cortisol. In conditions of prolonged stress, the level of insulin in the blood decreases and diabetes develops. The effect of cortisol and catecholamines in the resistance phase persists. The level of oxidative modification of blood plasma proteins indices depends on the behavior of the individual and changes in his psycho-emotional state, while a prolonged increase in the levels of catecholamines and cortisol in peripheral blood causes the development of psychosomatic pathology. It is proved that under the influence of complex action of risk factors there are significant changes in the psycho-emotional state that cause hypertension. This is confirmed by the presence of the highest level of reactive anxiety in patients with hypertension of the 1st stage on the background of the lowest personal anxiety which is the basis for the occurrence of the disease. With the progression of hypertension there are more profound changes in the personality of the patient, which is accompanied by the accumulation of personal anxiety, which can lead to a depressive state of neurotic genesis, which we observed with its complication. On the basis of a comprehensive study, the effect of stress on the occurrence of a syndrome of psychoemotional stress is shown, which leads to a steady increase in blood pressure - hypertension, and with its subsequent action complicates its course.
