Diagnosis Of Thyroid Cancer

Pulmonary metastases were found in 123 out of 840 patients with thyroid cancer between 1955-1977. 87 patients with pulmonary metastases of differentiated cancer were studied in detail, including an evaluation of prognostically important factors. In 66 of them, the induction of 131I uptake in metastases was attempted, in half of them successfully. Uptake was achieved more frequently in younger subjects, in papillary cancers and in patients with fine pulmonary metastases on chest films. Survival (not corrected for age) was evaluated 10 and 15 years following the diagnosis of thyroid cancer and was found to be 29,1 % and 12,2%, respectively. Significantly higher survival rates were seen in younger patients, in patients with the fine type of pulmonary metastases, in the absence of bone metastases and, particularly, in patients with induced 131I uptake in metastases. Papillary cancers were found to have higher survival rates in males and in young subjects only, in the whole group the survival rates were independent of either microscopic type or sex. It is believed that biologic behaviour of distant (pulmonary) metastases may be influenced by radioiodide therapy.

Age Range

SummaryAge-related trends in serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations were measured in 7248 euthyroid subjects (age-range 3 months to 106 years). 5700 were patients referred to hospitals for investigation of suspected thyroid dysfunction, but who were diagnosed euthyroid. 1548 were healthy blood donors (age-range 18-63 years) with no indication of thyroid dysfunction. FT4 concentrations were little affected by the age, the sex or the state of health of the subjects in either group. Serum FT3 concentrations were significantly affected by both age and health factors. The upper limit of the euthyroid reference range for young subjects up to 15 years was about 20% higher (10.4 pmol/1) than for adult subjects older than 25 years (8.8 pmol/1). The change in the upper limits typical of young subjects to that typical of adults occurred steadily over the decade 15–25 years. After this age, little further change occurred, especially in healthy subjects. Additionally, the lower limit of the euthyroid range for FT3 was extended by the inclusion in the reference group of patients referred to hospitals. Compared with the lower limit of the FT3 range for healthy subjects (5 pmol/1), the corresponding limit for referred subjects (young or adult) was 3.5–3.8 pmol/1. Broadening of the FT3 reference range was probably brought about by a significant number of patients in the hospital-referred group with the “1OW-T3 syndrome” of mild non-thyroidal illness. Accordingly, FT3 was inferior to FT4 in the discrimination of hypothyroidism, as FT4 was unaffected by this phenomenon. Effects of age and non-thyroidal illness on serum FT3 concentrations require great care when selecting subjects for a laboratory euthyroid reference range typical of the routine workload. Constraints on the choice of subjects for FT4 reference ranges are less stringent.

Drunk Driver

The present research aimed to assess some predictors for experiencing traveling in a car with a driver who has consumed alcohol, in a group of young people, aged between 18 and 20 years, residents of Timis County, Romania. The study group of 1606 young subjects, 18-20 years of age, 51.4% pupils and 48.6% students, with girls being significantly better represented, was applied a transversal population study. Percents of 29.8% of boys and 28.4% of girls got 1-3 times in a car with a drunk driver, and 10.1% of boys and 6.5% of girls traveled in such circumstances more than 4 times. Boys tend to accept the risks of traveling in a car with a drunk driver significantly more frequently than girls. We identified some predictors for traveling with a driver who has consumed alcohol, such as the binge drinking model and the model of mixed alcohol and drugs consumption, the practice of alcohol consumption associated with vehicle driving by the father, as well as by friends.

Joint Loads

BACKGROUND: Joint loads in different walking strategies during stair descent have been investigated in terms of the joint moment in association with the risk of osteoarthritis. However, the absorption mechanisms of the potential energy loss are not known. OBJECTIVE: This study aims to compare the mechanical energy absorptions in lower limb joints in different initial foot contact strategies. METHODS: Nineteen young subjects walked down on instrumented stairs with two different strategies, i.e., forefoot and rearfoot strike. Power and energy at lower limb joints during stance phase were compared between strategies. RESULTS: Lower limb joints absorbed 73 ± 11% of the potential energy released by descending stairs and there was no difference between strategies. Rearfoot strategy absorbed less energy than forefoot strategy at the ankle joint in the 1st phase, which was compensated mainly by more energy absorption at the knee in the 2nd phase and less energy generation at the hip joints in the 3rd phase. CONCLUSION: The results suggest that a leg absorbs most of the potential energy while descending stairs irrespective of the walking strategies and that any reduction of energy absorption at one joint is compensated by other joints. Greater energy absorption at the knee joint compared to the other joints suggests high burden of knee joint muscles and connective tissues during stair-descent, which is even more significant for the rearfoot strike strategy.
