Abstract Objectives Cervical component of thymus is noted more in children and young adults than in older age group. CT texture (lobules of soft tissue interspersed with fat), similarity with CT density of mediastinal thymus and continuity with mediastinal thymus on sagittal/coronal images, are given as the criteria for diagnosis of the cervical thymus. But CT densities of cervical and mediastinal components of the thymus may vary. The purpose of our study was to compare CT densities of cervical and mediastinal parts of the thymus, in cases where ultrasonography correlation was available. Methods We retrospectively identified 22 patients who had undergone CT between May 2015 and May 2017 and in whom ultrasonography (USG) correlation was available. CT densities of cervical and mediastinal components of thymus were measured. Results CT density of cervical thymus is lower than the CT density of mediastinal thymus by ~ 25 HU. There is a moderate positive correlation between CT densities of cervical and mediastinal parts of the thymus. CT densities of both cervical and mediastinal thymus were found to reduce with age, but the reduction was statistically significant only in the cervical thymus in this study. Conclusions CT densities of cervical and mediastinal components of the thymus may vary, with CT density of cervical thymus being lower. There is a positive correlation between CT densities of cervical and mediastinal parts of the thymus. CT density of cervical thymus reduces with age. Understanding these may help avoid confusion on CT and avoid the need for correlative USG, saving time and effort.

Abstract Background Coronavirus disease (COVID-19) is a respiratory syndrome with a variable degree of severity. Imaging is a vital component of disease monitoring and follow-up in coronavirus pulmonary syndromes. The study of temporal changes of CT findings of COVID-19 pneumonia can help in better understanding of disease pathogenesis and prediction of disease prognosis. In this study, we aim to determine the typical and atypical CT imaging features of COVID-19 and discuss the association of typical CT imaging features with the duration of the presenting complaint and patients’ age. Results The lesions showed unilateral distribution in 20% of cases and bilateral distribution in 80% of cases. The lesions involved the lower lung lobes in 30% of cases and showed diffuse involvement in 58.2% of cases. The lesions showed peripheral distribution in 74.5% of cases. The most common pattern was multifocal ground glass opacity found in 72.7% of cases. Atypical features like cavitation and pleural effusion can occur early in the disease course. There was significant association between increased number of the lesions, bilaterality, diffuse pattern of lung involvement and older age group (≥ 50 years old) and increased duration of presenting complaint (≥ 4 days). There was significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age. Conclusion The most common CT feature of COVID-19 was multifocal ground glass opacity. Atypical features like cavitation and pleural effusion can occur early in the course of the disease. Our cases showed more extensive lesions with bilateral and diffuse patterns of distribution in the older age group and with increased duration of presenting complaint. There was a significant association between crazy-paving pattern and increased duration of presenting complaint. No significant association could be detected between any CT pattern and increased patient age.

Introduction. All over the world and in Russia, the number of patients requiring dialysis therapy and kidney transplantation for chronic renal failure in the end-stage of the renal disease is increasing. In many countries of the world, the number of dialysis patients over 60 years of age accounts for 30 to 45% of all patients with chronic renal failure. Meantime, taking into account the improved methods for early diagnosis of chronic renal failure and the treatment methods for chronic kidney disease, including the renal replacement therapy, we can expect an increase in the number of elderly potential kidney transplant recipients. The likelihood of receiving a renal graft in elderly patients is significantly lower than in young recipients. Elderly patients are known to have a higher risk of death while waiting for a kidney transplant due to higher morbidity and lethality on dialysis. For this reason, the urgency of increasing the availability of kidney transplantation in elderly patients is growing over time. One of the solutions can be the use of kidneys from suboptimal donors with a far from ideal graft quality, but which could meet the needs for transplant care of the older age group of patients. The older age of a recipient entails a certain risk of developing a graft dysfunction due to the presence of concomitant diseases, and the potential risk increases even more with kidney transplants from expanded criteria donors. If a reduced functional reserve of kidneys removed from donors with extended criteria is identified, two-kidney transplantation is possible, which provides fairly good long-term results. To reduce the risk of a kidney graft loss, a careful selection of recipients is necessary, taking into account their co-morbidities, including the presence of urological diseases that impair the function of the upper and lower urinary tract. Their timely identification and correction makes it possible to raise the availability of kidney transplantation for elderly patients and improve its results. This review presents the results of the studies conducted in various world transplant centers, covers the mortality rates, kidney graft and recipient survival rates.The study purpose was to summarize the actual data and the results of the study on kidney transplantation in elderly patients with urological pathology.

Maintenance Requirements

The prosthetic episodes, i.e. actual processes of provision, identifying number of prostheses, their maintenance, repairs and replacements were analysed for 104 trans-tibial amputees aged 16 and over, over a 10 year period. The purpose of this investigation was to identify how frequently a new prosthesis is actually required for this group of amputees and what are their maintenance requirements. Variations of requirement between the amputee groups of aged 16–60 and over 60 years are also addressed. In the 10 years period of the study the amputees needed an average of 5.04 new prostheses, 6.25 refits, 2.28 major repairs and 17.04 day repairs. The younger amputees, i.e. below the age of 60 years, required significantly more new prostheses (p=0.003), more refit of sockets (p=0.0012) and more day repairs (p=0.01). Traumatic amputees below the age of 60 years needed significantly more day repairs compared to the non-traumatic amputees in the older age group (p=0.003).

BACKGROUND Severe oxidative stress has been reported in TB patients because of infection associated with malnutrition and poor immunity. Mycobacteria can induce reactive oxygen species (ROS) production by activating phagocytes, and enhanced ROS production may promote tissue injury and inflammation. We wanted to compare the effect of antioxidant administration in the outcome of ATT treatment between the test and the control group. METHODS This perspective study was conducted in the Departments of Biochemistry and Chest Medicine, CMC & Hospital. Hundred patients (fifty controls and fifty tests) who were diagnosed as pulmonary tuberculosis and started on DOT therapy under RNTCP during this period were included in the study. Each participant in the study was subjected to the following test at the first visit, 2nd month and 6th month follow up (biochemical markers Nitric oxide, SOD, Glutathione Peroxidase and Vitamin E levels). Statistical analysis was done using SPSS version. RESULTS The results were based on four categories (male / female, alcoholic / non-alcoholic, smoker / non-smoker, and younger / older age group). Females had responded better with greater fall in percentage of nitric oxide values (69 %) than males (64.1 %). The mean of SOD activity (277.5 + / - 31.5) was more in smokers than non-smokers (261.3 + / - 36.0) & percentage fall of nitric oxide in smokers (65 %) & non-smokers (67 %). In alcoholics the percentage fall of nitric oxide (68.3 %) was higher with more SOD activity (Mean 278.7 + / - 27.6) than non-alcoholics (Mean 256 + / - 38.0) indicating a positive correlation of smoking & alcoholism with tuberculosis. Younger age group responded better with more fall in the percentage of nitric oxide (67 %) & mean SOD activity (265.8 + / - 30.1) than older age group. CONCLUSIONS Antioxidant supplementation reduces oxidative stress, improves the effectiveness of ATT therapy, and thus helps in improving the outcome in pulmonary tuberculosis.

ObjectiveWe previously reported increasing free T3 (FT3) to free T4 (FT4) ratios as thyroid-stimulating hormone (TSH) increases within the normal range in children. It is not known if this phenomenon is age-related among humans, as previously reported in rats. This study examines the relationships between TSH and FT3/FT4 ratios in different ages.DesignRetrospective examination of thyroid tests from patients without thyroid disease from community clinics.MethodsFree T3, free T4, and TSH levels from 527 564 sera collected from patients aged 1 year or greater were studied. Exclusion criteria were the following: missing data, TSH greater than 7.5mIU/L, and medications that may interfere with thyroid hormone activity. A total of 27 940 samples remaining after exclusion were stratified by age. Samples with available anthropometric data were additionally stratified for body mass index (BMI). Correlations of TSH to FT4, FT3, and FT3/FT4 ratios by age group were examined.ResultsUp to age 40, for each increasing TSH quartile, FT3 and the FT3/FT4 ratio increased and FT4 decreased significantly (for both FT3, FT4 and FT3/FT4 ratio,P<0.05 for every TSH quartile when compared with the 1st quartile, except FT3 in the 30–40 age group). In older age groups, increasing TSH was not associated with increased FT3/FT4 ratio.ConclusionAs TSH levels increase, FT3/FT4 ratios increase until age 40, but this differential increase does not occur in older age groups. This may reflect a decrease in thyroxine (T4) to triiodothyronine (T3) conversion with age, which may be part of the aging process.
